<p>Introduction: Owing to its importance in the development and evaluation of health policies in favor of the general population, there is currently a greater interest in the study of well-being. Therefore, a valid and reliable measurement of well-being is necessary. In this context, this study evaluated the evidence of validity based on the internal structure, reliability, and factor invariance by sex of the General Well-Being Index (who-5 wbi). Materials and Methods: A total of 499 university students (female = 271; male = 228) from the city of Trujillo, Peru, participated in the study. A confirmatory factor analysis, reliability by internal consistency, and factor invariance by sex were performed using a multigroup analysis. Results: The confirmatory factor analysis indicated that the 5-dimensional model with 5 correlated errors of items 1 and 4 presented a good fit (χ² = 9.667 [gl = 4], p > 0.05; χ²/gl = 2.416; cfi = 0.994; rmsea = 0.053 [ic90% 0.006–0.097]; srmr = 0.018). In addition, acceptable reliability (ω = 0.758) and factor invariance by sex were reported. Conclusion: The who-5 wbi demonstrated empirical evidence in favor of validity based on internal structure, reliability of scores, and factor invariance that allow for a useful and rapid instrument for measuring subjective well-being in university students.</p>

<p>Background Latin America is undergoing a human resource crisis in health care in terms of labor shortage, misdistribution and poor orientation to primary care. Workforce data are needed to inform the planning of long-term strategies to address this problem. This study aimed to evaluate the academic and motivational profile, as well as the professional expectations, of Latin American medical students. Results We conducted an observational, cross-sectional, multi-country study evaluating medical students from 11 Spanish-speaking countries in 2011–2012. Motivations to study medicine, migration intentions, intent to enter postgraduate programs, and perceptions regarding primary care were evaluated via a self-administered questionnaire. Outcomes were measured with pilot-tested questions and previously validated scales. A total of 11,072 valid surveys from 63 medical schools were gathered and analyzed. Conclusions This study describes the profile and expectations of the future workforce being trained in Latin America. The obtained information will be useful for governments and universities in planning strategies to improve their current state of affairs regarding human resources for health care professions.</p>

<p>Furazolidone-resistant mutants were obtained from four clinical isolates of diarrhoeagenic Escherichia coli. The stability of the resistance and the frequency of mutation were established. The minimal inhibitory concentration of furazolidone, nitrofurantoin, nalidixic acid, ampicillin, chloramphenicol and tetracycline was established both in the presence and absence of the efflux pump inhibitor Phe-Arg-β-Naphtylamyde. The presence of mutations in the nitroreductase genes nfsA and nfsB was analysed by PCR; sequencing and their enzymatic activity was assessed by a spectrophotometric assay. Alterations in outer membrane proteins were studied by SDS-PAGE. The frequency of mutation ranged from <9.6 × 10-10 to 9.59 × 10-7 . Neither an effect on efflux pumps inhibited by Phe-Arg-β-Naphtylamyde nor cross-resistance with the antibiotics studied was observed. Nineteen mutants (52.94%) presented mutations in the nitroreductase-encoding genes: 17 in the nfsA gene (15 mutants with an internal stop codon, 2 with amino acid changes), 2 in the nfsB (all amino acid changes). Alterations in the outer membrane proteins OmpA and OmpW were also observed. Although more studies are necessary to find other resistance mechanisms, present data showed the low potential of selecting furazolidone-resistant mutants, together with the lack of cross-resistance with unrelated antimicrobial agents.</p>

<p>Objective: To evaluate the association between the use of a 3D virtual App and academic performance among Peruvian medical students. In addition, factors associated with academic performance were also assessed. Methods: We conducted an analytical cross-sectional study in students enrolled in the Musculoskeletal System course during the first semester of 2019. Students filled out a data collection form and the "Self-directed learning readiness scale" (SDLRS) questionnaire adapted by Fisher, King, and Tangle. Linear regression models were carried out to assess the association between the appropriate use of the application and academic performance. Additionally, the factors associated with academic performance were evaluated using nested models, and beta coefficients were calculated by manual forward selection. Results: A total of 187 medical students were included. The 61% were female and the median age was 21 [20-22] years. The average grade was 13.5 +/- 2 and 21% reported an adequate use of a 3D App. No association was found between the use of the 3D App and academic performance in the adjusted model (a beta = 0.17; 95% CI: -0.45 to 0.80). We found that age (a beta = -0.22; 95% CI: -0.39 to -0.06), performing extracurricular activities (a beta = 0.75, 95% CI: 0.25 to 1.24) and having failed an anatomy/physiology course before (a beta = -2.11 to 95% CI: -2.9 to -1.8) were factors associated with academic performance. Conclusion: The adequate use of a 3D application to study the anatomy of the musculoskeletal system was not significantly associated with better academic performance.</p>

<p>Introducción: La labor asistencial puede condicionar pobre dedicación a actividades de investigación científica en médicos que realizan la especialización de nefrología. Objetivo: Describir las prácticas de investigación científica entre los médicos residentes en nefrología y especialistas recién egresados en Perú. Material y métodos: Se realizó un estudio descriptivo de corte transversal sobre la totalidad de médicos residentes de nefrología de los dos últimos años y especialistas egresados de los dos últimos años a nivel nacional, mediante un cuestionario autoaplicado. Resultados: Se obtuvieron 40 respuestas, de las cuales el 50% correspondían a residentes. El 67.5% de los encuestados nunca realizó investigación durante la residencia. Ningún encuestado que haya realizado algún trabajo de investigación lo publicó. Casi todos consideraron a su sede hospitalaria como deficiente en investigación. Conclusión: La investigación científica entre residentes de nefrología en Perú es deficiente. Se requieren estrategias que la promuevan a este nivel.</p>

<p>Background: Antepartum depression is one of the leading causes of maternal morbidity and mortality in the prenatal period. There is accumulating evidence for the role of brain-derived neurotrophic factor (BDNF) in the pathophysiology of depression. The present study examines the extent to which maternal early pregnancy serum BDNF levels are associated with antepartum depression. Method: A total of 968 women were recruited and interviewed in early pregnancy. Antepartum depression prevalence and symptom severity were assessed using the Patient Health Questionnaire-9 (PHQ-9) scale. Maternal serum BDNF levels were measured using a competitive enzyme-linked immunosorbent assay (ELISA). Logistic regression procedures were performed to estimate odds ratios (OR) and 95% confidence intervals (95% CI) adjusted for confounders. Results: Maternal early pregnancy serum BDNF levels were significantly lower in women with antepartum depression compared to women without depression (mean ± standard deviation [SD]: 20.78 ± 5.97 vs. 21.85 ± 6.42 ng/ml, p = 0.024). Lower BDNF levels were associated with increased odds of maternal antepartum depression. After adjusting for confounding, women whose serum BDNF levels were in the lowest three quartiles (25.31 ng/ml). There was no evidence of an association of BDNF levels with depression symptom severity. Conclusions: Lower maternal serum BDNF levels in early pregnancy are associated with antepartum depression. These findings may point toward new therapeutic opportunities and BDNF should be assessed as a potential biomarker for risk prediction and monitoring response to treatment for antepartum depression.</p>

<p>Small and medium-sized enterprises (SMEs) in Peru present problems such as access to the national market due to limited capital or access to technology compared to large companies. However, they also lack an adequate definition and conceptualization of their processes, as well as a low level of business information transfer, which causes an absence in the measurement, control of processes and low operational performance. Given this situation, we propose the application and implementation of knowledge management tools in a company dedicated to the marketing and distribution of school supplies, which represents an SME in Peru. The tools used as the map of processes and flowcharts of the different processes were used to make the participants of the processes known. Through the realization of training, performance evaluations and internal audit, the learning of the operator is analyzed. As a result, there was a 57.63% decrease in errors in armed orders during picking, as well as a decrease of 7.98% and 8.59% of times in the execution of the processes under study for small orders and larger orders, respectively. Similarly, 96.56% of dispatches generated correctly were obtained.</p>

<p>Background: The main cause of death in HIV patients is tuberculosis (TB). However, few Latin American studies have evaluated the prognosis of patients with coinfection. Aim: To determine the factors associated with survival in patients with HIV-TB coinfection treated at a Peruvian referral hospital. Methods: A retrospective cohort study was performed based on clinical records of patients treated at the Department of Infectious Diseases in the Arzobispo Loayza National Hospital from 2004 to 2012. Survival was assessed using the Kaplan-Meier estimator and Cox Proportional Hazard Model. Results: From 315 patients, 82 died during the follow-up. The mean of follow for each patient was 730 days. The multivariate analysis showed that receiving HAART (HR: 0,31; IC: 0,20-0,50; p < 0,01) and having more weight (HR: 0,96; IC 0,94–0,98; p < 0,01) when the coinfection was diagnosed, were protective factors; while having a pathology different from TB (HR: 1,88; IC: 1,19-2,98; p < 0,01), age in years (HR: 1,76; IC: 1,12-2,74; p ≤ 0,01) and being hospitalized when diagnosed with TB (HR: 1,69; IC 1,02-2,80; p < 0,04) were associated with lower survival. Discussion: Receiving HAART and having more weight when the coinfection is diagnosed were associated with a higher chance of survival.</p>

<p>Introduction: Bartonella bacilliformis is the etiological agent of Carrion’s disease, which is a neglected disease linked to people in low-socioeconomic populations in Andean valleys. An outbreak of B. bacilliformis was reported in a rural area of the Peruvian Amazon region. The aim of this study was to characterize this outbreak using molecular techniques. Methodology: Fifty-three blood samples from patients diagnosed with Carrion’s disease were analyzed by molecular tools, using both a Bartonella-specific polymerase chain reaction (PCR) and an universal PCR, both based on 16S rRNA gene amplification. Additional water samples from the area were also analyzed. Results: Unexpectedly, the samples were positive only when the universal PCR was used. Although environmental contamination cannot be ruled out, the results showed that Sphingomonas faeni was the possible causative agent of this outbreak, and that water was the most feasible infection source. Conclusions: Diagnosis by clinical criteria or microscopy may lead to misdiagnosis. There is a need to include molecular tools in the routine diagnosis of febrile syndromes, including Carrion’s disease.</p>

<p>Technological advances have allowed to collect and store large volumes of data over the years. Besides, it is significant that today's applications have high performance and can analyze these large datasets effectively. Today, it remains a challenge for data mining to make its algorithms and applications equally efficient in the need of increasing data size and dimensionality [1]. To achieve this goal, many applications rely on parallelism, because it is an area that allows the reduction of cost depending on the execution time of the algorithms because it takes advantage of the characteristics of current computer architectures to run several processes concurrently [2]. This paper proposes a parallel version of the FuzzyPred algorithm based on the amount of data that can be processed within each of the processing threads, synchronously and independently.</p>

<p>Today, eavesdropping is becoming a common issue in the rapidly growing digital network and has foreseen the need for secret communication channels embedded in digital media. In this paper, a novel steganography technique designed for Standard Definition Digital Television (SDTV) H.264/AVC encoded video sequences is presented. The algorithm introduced here makes use of the compression properties of the Context Adaptive Variable Length Coding (CAVLC) entropy encoder to achieve a low complexity and real-time inserting method. The chosen scheme hides the private message directly in the H.264/AVC bit stream by modifying the AC frequency quantized residual luminance coefficients of intrapredicted I-frames. In order to avoid error propagation in adjacent blocks, an interlaced embedding strategy is applied. Likewise, the steganography technique proposed allows self-detection of the hidden message at the target destination. The code source was implemented by mixing MATLAB 2010 b and Java development environments. Finally, experimental results have been assessed through objective and subjective quality measures and reveal that less visible artifacts are produced with the technique proposed by reaching PSNR values above 40.0 dB and an embedding bit rate average per secret communication channel of 425 bits/sec. This exemplifies that steganography is affordable in digital television.</p>

<p>Introduction: Pneumonia and diarrhoea are leading causes of death in children. There is a need to develop effective interventions. Objective: We present the design and baseline findings of a community-randomised controlled trial in rural Peru to evaluate the health impact of an Integrated Home-based Intervention Package in children aged 6 to 35 months. Methods: We randomised 51 communities. The intervention was developed through a community-participatory approach prior to the trial. They comprised the construction of improved stoves and kitchen sinks, the promotion of hand washing, and solar drinking water disinfection (SODIS). To reduce the potential impact of non-blinding bias, a psychomotor stimulation intervention was implemented in the control arm. The baseline survey included anthropometric and socio-economic characteristics. In a sub-sample we determined the level of faecal contamination of drinking water, hands and kitchen utensils and the prevalence of diarrhoegenic Escherichia coli in stool specimen. Results: We enrolled 534 children. At baseline all households used open fires and 77% had access to piped water supplies. E. coli was found in drinking water in 68% and 64% of the intervention and control households. Diarrhoegenic E. coli strains were isolated from 45/139 stool samples. The proportion of stunted children was 54%. Conclusions: Randomization resulted in comparable study arms. Recently, several critical reviews raised major concerns on the reliability of open health intervention trials, because of uncertain sustainability and non-blinding bias. In this regard, the presented trial featuring objective outcome measures, a simultaneous intervention in the control communities and a 12- month follow up period will provide valuable evidence.</p>

<p>Objective: To evaluate the antibacterial and cytotoxic effect of Myrciaria dubia (Camu camu) (M. dubia) methanol extract, against Streptococcus mutans (ATCC 25175) (S. mutans) and Streptococcus sanguinis (ATCC 10556) (S. sanguinis). Methods: Two methanol extracts of M. dubia were prepared in vitro, from the seeds and pulp. Ten independent tests were prepared for each type of extract, using 0.12% chlorhexidine solution as positive control. Agar diffusion test was used by preparing wells with the experimental solutions cultivated in anaerobic conditions for 48 h at 37 °C. Meanwhile, the minimum inhibitory concentration and the cytotoxic effect over MDCK cell line was found. Results: A higher antibacterial effect was observed with the methanol seed extract with an inhibitory halo of (21.36 ± 6.35) mm and (19.21 ± 5.18) mm against S. mutans and S. sanguinis, respectively. The methanol extract of the pulp had an effect of (16.20 ± 2.08) mm and (19.34 ± 2.90) mm, respectively. The minimum inhibitory concentration of the pulp extract was 62.5 µg/mL for both strains, whereas for the seed antibacterial activity was observed even at low concentrations. The CC50 of the seeds extract was at a higher concentration than 800 µg/mL and 524.37 µg/mL for the pulp extract.</p>

<p>The aim of the study was to analyze the psychometric properties of the Spanish version of the Coronavirus Anxiety Scale (CAS), using Item Response Theory (IRT) and Confirmatory Factor Analysis (CFA). The participants were 790 Peruvians, selected through a convenience sampling, where the majority were women. The CFA models indicated that the one-dimensional structure better represents the data, is reliable and invariant between men and women. Likewise, IRT findings indicate that CAS is more informative for high levels of COVID-19 anxiety. The CAS in Spanish has adequate psychometric properties to be used as a short measure of COVID-19 anxiety.</p>

<p>The concept of entrustable professional activities emerged as an attempt to overcome some of the criticisms to the competency-based medical education approach; it has had a broad impact in practice and health professions education research. It has been disseminated internationally with its English acronym: EPA. This approach proposes to orient assessment and teaching to specific activities in the profession, which allows the integration of several competencies, and to determine which responsibilities can be entrusted to the trainee, in a gradual and explicit manner. The model assumes the definition of levels of supervision that allow progressive autonomy for each EPA, in students or residents, once they demonstrate the required competencies. Practice, supervision and feedback in real clinical scenarios are key to the development of autonomy in EPA performance. The dissemination of the EPA approach is still limited in Latin America, but it has the potential to create a significant contribution to curriculum design and evaluation, and to assessment practices of health professionals across their careers. It provides a deep review of the assumptions under which healthcare professional practice decisions are made, at under and postgraduate levels.</p>

<p>The construction of coastal ports requires the use of materials that meet the demands of the marine environment, to prevent underwater concrete structures from cracking and spalling easily; basalt fiber is used to delay the expansion of concrete and prevent the formation of cracks. This research studies the behavior of concrete for prefabricated piles with Portland Cement Type I and basalt fibers added in 0.1%, 0.3% and 0.6%; the results indicate that the fiber is suitable for concrete, the slump decreases, the compressive strength increases for specimens cured in tap water and sea water, the relationship between resistances does not vary, and the depth of carbonation decreases.</p>

<p>Objective: To review evidence on the efficacy of HPV vaccines in the prevention of non-cancer lesions (anogenital warts [AGW], recurrent laryngeal papillomatosis and oral papillomatosis). Materials and methods: We conducted a systematic review of randomized trials. We performed random effect models and effects were reported as relative risks (RR) and their confidence intervals (95%CI) following both intention to treat (ITT) and per protocol (PP) analyses. Results: We included six studies (n=27 078). One study was rated as high risk of bias. One study could not be included in the meta-analysis because it provided combined results. We found that quadrivalent vaccine reduced the risk of AGW by 62% (RR: 0.38, 95%CI:0.32-0.45, I2:0%) in the ITT analysis and by 95% (RR: 0.05, 95%CI:0.01-0.25, I2:66%) in the PP analysis. Subgroup analyses of studies in women or with low-risk of bias provided similar results. Conclusion: HPV quadrivalent vaccine is efficacious in preventing AGW in men and women.</p>

<p>El carcinoma medular de tiroides (CMT) es un tipo de neoplasia maligna infrecuente, con alto índice metastásico. Se presenta como un solo nódulo en más del 70% de los casos, y los principales órganos de metástasis a distancia son el hígado, el pulmón y el hueso. La metástasis en mama es rara, debido a que dentro de los tumores mamarios, solo entre el 0.2-1.3% son secundarios. El CMT se relaciona íntimamente con la neoplasia endocrina múltiple subtipo 2B (NEM2B), la cual es un desorden autosómico dominante caracterizado por la presencia de CMT y feocromocitoma en ausencia de hiperparatiroidismo. Rara vez, en el contexto de un NEM2B ocurre una metástasis de CMT en la mama, motivo por el cual se está presentando este caso</p>

<p>The damage assessment caused by floods, earthquakes, hurricanes among others phenomenons in the world are analyzed with methodologies such as "Vulnerability curves". In Peru, disasters caused by hyperconcentrated flows are alarming due to a climatic variability such as the "El Nio Costero"phenomenon. Therefore, this research has developed vulnerability curves for 1 and 2-story confined masonry buildings in Urb. San Idelfonso, Ica - Peru; linking the variables: flow depth, associated with the event produced by heavy rains at the top of the "Quebrada Cansas"caused by the "El Nio Costero"phenomenon in 2017, and the percentage of the damage based on the methodology of the United States Army Corps of Engineers (USACE), whose formula is the repair value and total building value. The monetary amounts and items of the buildings are obtained from the RM 415-2017-VIVIENDA of the Ministry of Housing, Construction and Sanitation of Peru. The process consisted of hydrological modeling in HEC-HMS, hydraulic modeling in FLO-2D, damage percentage estimate and vulnerability curves production. Finally, the vulnerability curves for hyperconcentrated flows were contrasted with similar studies regarding curves for flooding and debris flow. The results of the investigation showed that the "El Nio Costero"phenomenon in 2017 had an economic impact of at least 1.3 million soles in Urb. San Idelfonso. In addition, at least 24 buildings had a complete damage and 21 buildings an extensive damage.</p>

<p>Background The lack of an effective diagnostic tool for Carrion’s disease leads to misdiagnosis, wrong treatments and perpetuation of asymptomatic carriers living in endemic areas. Conventional PCR approaches have been reported as a diagnostic technique. However, the detection limit of these techniques is not clear as well as if its usefulness in low bacteriemia cases. The aim of this study was to evaluate the detection limit of 3 PCR approaches. Methodology/Principal Findings We determined the detection limit of 3 different PCR approaches: Bartonella-specific 16S rRNA, fla and its genes. We also evaluated the viability of dry blood spots to be used as a sample transport system. Our results show that 16S rRNA PCR is the approach with a lowest detection limit, 5 CFU/μL, and thus, the best diagnostic PCR tool studied. Dry blood spots diminish the sensitivity of the assay. Methodology/Principal Findings We determined the detection limit of 3 different PCR approaches: Bartonella-specific 16S rRNA, fla and its genes. We also evaluated the viability of dry blood spots to be used as a sample transport system. Our results show that 16S rRNA PCR is the approach with a lowest detection limit, 5 CFU/μL, and thus, the best diagnostic PCR tool studied. Dry blood spots diminish the sensitivity of the assay. Conclusions/Significance From the tested PCRs, the 16S rRNA PCR-approach is the best to be used in the direct blood detection of acute cases of Carrion’s disease. However its use in samples from dry blood spots results in easier management of transport samples in rural areas, a slight decrease in the sensitivity was observed. The usefulness to detect by PCR the presence of low-bacteriemic or asymptomatic carriers is doubtful, showing the need to search for new more sensible techniques.</p>

<p>BACKGROUND: Diarrheagenic Escherichia coli strains are being recognized as important pediatric enteropathogens worldwide. However, it is unclear whether there are differences in age-related susceptibility to specific strains, especially among infants. METHODS: We conducted a passive surveillance cohort study of diarrhea that involved 1034 children aged 2-12 months in Lima, Peru. Control stool samples were collected from randomly selected children without diarrhea. All samples were analyzed for common enteric pathogens and for diarrheagenic E. coli with use of multiplex real-time polymerase chain reaction. RESULTS: The most frequently isolated pathogens in 1065 diarrheal episodes were diarrheagenic E. coli strains (31%), including enteroaggregative (15.1%) and enteropathogenic E. coli (7.6%). Diarrheagenic E. coli, Campylobacter species, and rotavirus were more frequently isolated from infants aged >or=6 months. Among older infants, diffusely adherent E. coli and enterotoxigenic E. coli were more frequently isolated from diarrheal samples than from control samples (P <.05). Children aged >or=6 months who were infected with enterotoxigenic E. coli had a 4.56-fold increased risk of diarrhea (95% confidence interval, 1.20-17.28), compared with younger children. Persistent diarrhea was more common in infants aged <6 months (13.5% vs 3.6%; P <.001). Among children with diarrheagenic E. coli-positive samples, coinfections with other pathogens were more common in children with diarrhea than in control children (40.1% vs 15.6%; P <.001). CONCLUSIONS: Diarrheagenic E. coli strains were more frequently isolated in samples from older infants. In this setting with high frequency of pathogen exposure and high frequency of breastfeeding, we hypothesize that the major age-related differences result from decreased exposure to milk-related protective factors and from increased exposure to contaminated food and water.</p>

<p>Introduction—Chronic kidney disease (CKD) affects 50 million people globally. Several studies show the importance of implementing interventions that enhance patients' knowledge about their disease. In 2011, the Kidney Disease Knowledge Survey (KiKS) was developed, a questionnaire that assesses the specific knowledge about CKD in pre-dialysis patients. Objective—To translate to Spanish, culturally adapt and validate the questionnaire KiKS in a population of patients with pre-dialysis CKD. Methods—The translation and cultural adaptation of KiKS was performed. Subsequently, its validity and reliability were determined. The validity was evaluated by construct validity; and the reliability by its internal consistency and its intra-observer reliability (test-retest). Results—A good internal consistency was found (Kuder-Richardson = 0.85). Regarding intraobserver reliability, the intraclass correlation coefficient with a value of 0.78 (95% CI: 0.5–1.0) indicated a good reproducibility; the mean difference of −1.1 test-retest S.D. 6.0 (p = 0.369) confirm this.</p>

<p>During host colonization, bacteria use the alarmones (p)ppGpp to reshape their proteome by acting pleiotropically on DNA, RNA, and protein synthesis. Here, we elucidate how the initiating ribosome senses the cellular pool of guanosine nucleotides and regulates the progression towards protein synthesis. Our results show that the affinity of guanosine triphosphate (GTP) and the inhibitory concentration of ppGpp for the 30S-bound initiation factor IF2 vary depending on the programmed mRNA. The TufA mRNA enhanced GTP affinity for 30S complexes, resulting in improved ppGpp tolerance and allowing efficient protein synthesis. Conversely, the InfA mRNA allowed ppGpp to compete with GTP for IF2, thus stalling 30S complexes. Structural modeling and biochemical analysis of the TufA mRNA unveiled a structured enhancer of translation initiation (SETI) composed of two consecutive hairpins proximal to the translation initiation region (TIR) that largely account for ppGpp tolerance under physiological concentrations of guanosine nucleotides. Furthermore, our results show that the mechanism enhancing ppGpp tolerance is not restricted to the TufA mRNA, as similar ppGpp tolerance was found for the SETI-containing Rnr mRNA. Finally, we show that IF2 can use pppGpp to promote the formation of 30S initiation complexes (ICs), albeit requiring higher factor concentration and resulting in slower transitions to translation elongation. Altogether, our data unveil a novel regulatory mechanism at the onset of protein synthesis that tolerates physiological concentrations of ppGpp and that bacteria can exploit to modulate their proteome as a function of the nutritional shift happening during stringent response and infection.</p>

<p>Purpose: To assess whether the participation in food assistance programs (Community Kitchens and Glass of Milk) was associated with lipid profile patterns in the Peruvian population. We conducted a secondary data analysis using data from the National Survey of Nutritional, Biochemical, Socioeconomic, and Cultural Indicators related to Chronic Degenerative Diseases. The sample included individuals aged ≥20 years, selected from five geographic strata in Peru. From each stratum a random sample of clusters was chosen. Different Poisson regression models with robust variance were built to determine the association between food assistance programs and participant lipid profile (total cholesterol (TC), HDL-cholesterol (HDL-c), LDL-cholesterol and triglycerides (TG)). Data from 4028 participants was analyzed, 123 (3.1%) reported being beneficiaries of the Community Kitchens program and 827 (20.5%) were beneficiaries of the Glass of Milk program. An association between being a beneficiary of Community Kitchens and increased LDL-c (Prevalence ratio (PR)= 2.33; 95% CI: 1.18–4.59) was found. Being a beneficiary of the Glass of Milk program increased the probability of having low HDL-c levels (PR= 1.08; 95% CI: 1.02–1.14), but reduced the probability of hypertriglyceridemia (PR= 0.70; 95% CI: 0.56–0.88). Being a beneficiary of the Community Kitchen program was associated with increased LDL-c levels; while, being a beneficiary of the Glass of Milk increased the probability of low HDL-c, but reduced the probability of developing hypertriglyceridemia.</p>

<p>El término de “cambio climático” no es un concepto nuevo, pero su impacto en la salud pública está en continua revisión. Sabemos que el clima ya cambió y va seguir cambiando por los próximos siglos con el aumento de la temperatura global promedio, y el consecuente aumento del nivel del mar. Este hecho hace que los esfuerzos para la mitigación de la emisión de gases sean relevantes únicamente a muy largo plazo y para generaciones de humanos cuyos padres aun no nacen. Si hablamos de salud pública en el contexto de cambio climático, hablamos de adaptación. En el presente, los países más afectados por los efectos del cambio climático son justamente los países como el Perú, sin una huella ecológica significativa a nivel mundial, pero que son altamente sensibles a los efectos del clima. Sin proyecciones confiables del cambio en el clima, el impacto en la salud puede ser incierto y complicado. Sin embargo, a nivel local, cada distrito puede identificar sus propias vulnerabilidades y definir sus prioridades para asegurar la salud de su población. Existen y se pueden crear indicadores de salud ambiental para monitorizar qué tan bien nos estamos adaptando y qué tan preparados estamos para los cambios en el clima. La adaptación a los cambios del clima implica elevar las condiciones de vida, mejorar los sistemas de vigilancia epidemiológica y ampliar el acceso a servicios de salud. La lucha contra los efectos del cambio climático en salud pública es la lucha contra la pobreza y la desigualdad, y eso no es nada nuevo en el Perú.</p>

<p>Objetivos. Determinar los factores asociados al uso regular de fuentes de información en estudiantes de Medicina de cuatro ciudades de Perú. Materiales y métodos. Estudio transversal analítico, se encuestó a estudiantes de Medicina de cuatro ciudades del Perú, recopilando información del uso de 14 fuentes de información y otras variables educativas e informáticas. Se definió uso frecuente de la fuente de información si accedía a ella mínimo una vez a la semana. Se obtuvieron los valores p mediante modelos lineales generalizados ajustando por la sede de cada encuestado. Resultados. Se encuestaron 2300 estudiantes con una mediana de edad de 21 años, el 53% fueron mujeres. El recibir una capacitación para el uso de las fuentes incrementó el uso en doce de las bases consultadas, no en SciELO (p=0,053) ni en la biblioteca universitaria (p=0,509). Cuando se añadió el ajuste por poseer una laptop/netbook se mantuvieron dichas asociaciones. Al ajustar también por poseer un smartphone se perdió la asociación con la base BVS Perú (p=0,067), lo mismo ocurrió al hacer el último ajuste, si había realizado alguna actividad de investigación. Conclusiones. El uso frecuente de las fuentes de la información está asociado con haber recibido capacitación, realizar investigación y el uso de las tecnologías de la información y comunicación. Esto debe ser tomado en cuenta en programas de capacitación y mejora continua en el pre y posgrado.</p>

<p>BACKGROUND: For the last 15 years, infection from Helicobacter pylori (H. pylori) has been recognized in gastritis pathogenesis, and is known to trigger an important inflammatory response in these patients. AIM: To determine the association between follicular gastritis and the infection of H. pylori in children seen at a public hospital in Peru. METHODOLOGY: An analytic, cross-sectional study was conducted on all the children treated at the Hospital Nacional Docente Madre "Niño San Bartolomé" in Lima, Peru, within the time frame of 2011-2012. All the personal data from the patients' medical histories and endoscopic procedures were collected. The crude prevalence ratios (PR) were obtained and adjusted (aPR) with their 95% confidence intervals (95%CI), using generalized linear models with the binomial family and log link function. RESULTS: A total of 123 children met the study criteria. Forty-eight (39%) of the study sample were girls and the mean age of the children was 12 years. H. pylori was present in 44% of the sample and 9% presented with more than 100 bacteria per field (classified as +++). Thirty-five percent of the children had esophagitis due to concomitant reflux. The presence of H. pylori was associated with follicular gastritis (P<.01; PRa: 2.3; 95% CI:1.49-3.49), adjusted by the children's age. CONCLUSIONS: Based on the data analyzed, it was concluded that the children with follicular gastritis had a greater likelihood of having H. pylori than those that did not present with gastritis. These results can be extrapolated to other similar populations and should be evaluated in each setting so that this does not become a public health problem within the next few years.</p>

<p>Objective: To determine the association between body image dissatisfaction (BID) and depressive symptoms in adolescents from a school in Lima, Peru. Methods: A cross-sectional study was performed through a census of 875 high-school students, aged 13 to 17 years, from a school in Lima. Participants completed a survey containing the Body Shape Questionnaire (BSQ) and the Patient Health Questionnaire-9 (PHQ-9). Data regarding demographics, alcohol and tobacco use, self-esteem, and family history of depression were also obtained. To identify associated factors, Poisson regression with robust variance was used. Prevalence ratios with 95% confidence intervals were calculated. Results: Of the 875 adolescents, 55.8% were male. The mean age was 14.161.5 years. Depressive symptoms were observed in 19.9% of participants. An association between BID and depressive symptoms was found. Alcohol and tobacco use were also associated with the outcome of interest. Conclusions: Teens who had BID were 3.7 times more likely to report depressive symptoms. Additionally, those who used tobacco or alcohol were 1.5 and 1.4 times more likely to have depressive symptoms, respectively. Further studies targeting other populations and using longitudinal designs are recommended.</p>

<p>Interpersonal partner violence (IPV) is a worldwide public health problem. As a result of IPV, victims report high rates of physical and behavioral disabilities. Help-seeking behaviors are key to obtaining support on facing and managing IPV. Cultural practices such as machismo, marianismo, and familismo are related to keeping quiet and remaining in an abusive relationship in Latinas. Difficulties in sharing emotions, setting interpersonal boundaries, and communicating needs are also behavioral barriers to seeking help in this population. All these factors are associated with social disconnection which reduces victims’ chances of obtaining support in risky situations. Although several programs have been developed for helping victims of IPV, more evidence on adaptions to particular cultural and interpersonal struggles faced by Latinas’ victims is needed. Functional Analytic Psychotherapy (FAP) proposes that therapeutic relationships based on intimacy can help victims of IPV to identify characteristics of those relationships that provide help when they need it. In this theoretical article, several FAP-based strategies aid therapists working with Latinas’ victims of IPV in strengthening clients’ interpersonal functioning and defeating cultural barriers when seeking help.</p>

<p>Objective: To determine the association between the perception of practical advice and the educational messages of the food guides in students of a private university in Peru. Methodology: Cross-sectional study. The population corresponded to undergrads who are from the first to tenth semester of their degrees in a private university of Lima-Peru. The sample was 480 university students who voluntarily agreed to participate in the study. The data were collected in the period from october to november of the year 2019. A questionnaire was applied to collect the perception of university students about the messages of the dietary guidelines and the media where they would like to know information about educational messages. Results: 46.5% correspond to undergrads of the Faculty of Health Sciences. Messages 1, 3, 4, 6, 9 and 11 of the Peruvian GABAS showed an evident statistical association (p <0.05). The media with the highest proportion by which they would like to know educational messages about healthy eating were Television (28.5%), Instagram (27.7%) and Facebook (19.0%). Conclusion: Differentiated advertising should be designed and implemented on television, Instagram and Facebook on healthy eating to contribute to the improvement of the health and nutrition status of Peruvian university students.

<p>Introduction: Bordetella pertussis is an important human pathogen that causes whooping cough (pertussis), an endemic illness responsible of significant morbidity and mortality, especially in infants and children. Worldwide, there are an estimated of 16 million cases of pertussis, resulting in about 195,000 child deaths per year. In Peru, pertussis is a major health problem that has been on the increase despite immunization efforts. The objective of this study was to determine the prevalence of B. pertussis among children under five years of age suspected to have whopping cough in Cajamarca, Peru. Methodology: Children diagnosed with whooping cough admitted to the Hospital Regional de Cajamarca from August 2010 to July 2013 were included. Nasopharyngeal samples were obtained for B. pertussis culture and polymerase chain reaction (PCR) detection. Results: In 133 children, the pertussis toxin and IS481 gene were detected in 38.35% (51/133) of the cases by PCR, while only 9.02% (12/133) of the Bordetella cultures were positive. The most frequent symptoms in patients with positive B. pertussis were paroxysm of coughing 68.63% (35/51), cyanosis 56.86% (29/51), respiratory distress 43.14% (22/51), and fever 39.22% (20/51). Pneumonia and acute bronchial obstructive syndrome were present in 17.65% (9/51) and 13.72% (7/51) of the cases, respectively. Conclusions: B. pertussis is responsible for an important proportion of whooping cough in hospitalized children in Cajamarca. Epidemiologic surveillance programs for B. pertussis are essential in Peru, especially in children who could most benefit from the vaccine.</p>

<p>Objectives: Diagnosis of pleural tuberculosis (PT) is still a challenge, particularly in resource-constrained settings. Alternative diagnostic tools are needed. We aimed at evaluating the utility of Clinical Prediction Rules (CPRs) for diagnosis of pleural tuberculosis in Peru. Methods: We identified CPRs for diagnosis of PT through a structured literature search. CPRs using high-complexity tests, as defined by the FDA, were excluded. We applied the identified CPRs to patients with pleural exudates attending two third-level hospitals in Lima, Peru, a setting with high incidence of tuberculosis. Besides pleural fluid analysis, patients underwent closed pleural biopsy for reaching a final diagnosis through combining microbiological and histopathological criteria. We evaluated the performance of the CPRs against this composite reference standard using classic indicators of diagnostic test validity. Results: We found 15 eligible CPRs, of which 12 could be validated. Most included ADA, age, lymphocyte proportion and protein in pleural fluid as predictive findings. A total of 259 patients were included for their validation, of which 176 (67%) had PT and 50 (19%) malignant pleural effusion. The overall accuracy of the CPRs varied from 41% to 86%. Two had a positive likelihood ratio (LR) above 10, but none a negative LR below 0.1. ADA alone at a cut-off of ≥40 IU attained 87% diagnostic accuracy and had a positive LR of 6.6 and a negative LR of 0.2. Conclusion: Many CPRs for PT are available. In addition to ADA alone, none of them contributes significantly to diagnosis of PT.</p>

<p>We aimed to elucidate the role of vitamin D supplementation on adipokines through a systematic review and a meta-analysis of randomized placebo-controlled trials (RCTs). The search included PUBMED, Scopus, Web of Science and Google Scholar through July 1st, 2015. Finally we identified 9 RCTs and 484 participants. Meta-analysis of data from 7 studies did not find a significant change in plasma adiponectin concentrations following vitamin D supplementation (mean difference [MD]: 4.45%, 95%CI: -3.04, 11.93, p=0.244; Q=2.18, I(2)=0%). In meta-regression, changes in plasma adiponectin concentrations following vitamin D supplementation were found to be independent of treatment duration (slope: 0.25; 95%CI: -0.69, 1.19; p=0.603) and changes in serum 25-hydroxy vitamin D [25(OH)D] levels (slope: -0.02; 95%CI: -0.15, 0.12; p=0.780). Meta-analysis of data from 6 studies did not find a significant change in plasma leptin concentrations following vitamin D supplementation (MD: -4.51%, 95%CI: -25.13, 16.11, p=0.668; Q=6.41, I(2)=21.97%). Sensitivity analysis showed that this effect size is sensitive to one of the studies; removing it resulted in a significant reduction in plasma leptin levels (MD: -12.81%, 95%CI: -24.33, -1.30, p=0.029). In meta-regression, changes in plasma leptin concentrations following vitamin D supplementation were found to be independent of treatment duration (slope: -1.93; 95%CI: -4.08, 0.23; p=0.080). However, changes in serum 25(OH)D were found to be significantly associated with changes in plasma leptin levels following vitamin D supplementation (slope: 1.05; 95%CI: 0.08, 2.02; p=0.033). In conclusion, current data did not indicate a significant effect of vitamin D supplementation on adiponectin and leptin levels.</p>

<p>We have read with interest the short communication published by Segovia-Juarez et al., 2020 in Respiratory Physiology & Neurobiology establishing that high altitude reduces the infection rate of COVID-19 but not the case fatality rate in the Peruvian setting. We support this hypothesis, however there could be an important number of under registered deaths on account of a low rate of diagnostic tests performed per inhabitant and mostly in symptomatic patients (Pasquariello and Stranges, 2020).</p>

<p>BACKGROUND: Suicide is a leading cause of maternal death globally, and suicide prevalence rates have been shown to be increased in those with migraine. No previous study has examined the association between migraine and suicidal ideation during pregnancy. OBJECTIVE: To examine the association between migraine and suicidal ideation among a cohort of pregnant women. METHODS: A cross-sectional study was conducted among 3372 pregnant women attending prenatal care clinics in Lima, Peru. Suicidal ideation and depression were assessed using the Patient Health Questionnaire-9 (PHQ-9) scale during early pregnancy. Migraine classification (including migraine and probable migraine) was based on International Classification of Headache Disorders-III beta criteria. Multivariable logistic regression analyses were performed to estimate odds ratios (OR) and 95% confidence intervals (95%CI). RESULTS: Suicidal ideation was more common among those with migraine (25.6%) as compared to those with probable migraine (22.1%, P < .001) or non-migraineurs (12.3%, P < .001). After adjusting for confounders, including depression, those with migraine or probable migraine had a 78% increased odds of suicidal ideation (OR = 1.78; 95% CI: 1.46-2.17), as compared with non-migraineurs. Women with both migraine and depression had a 4.14-fold increased odds of suicidal ideation (OR = 4.14; 95% CI: 3.17-5.42) compared to those with neither condition. CONCLUSION: Migraine is associated with increased odds of suicidal ideation in pregnant women even when controlling for depression. These findings support the consideration of screening women with comorbid migraine and depression for suicidal behavior during pregnancy.</p>

<p>Traditional forecasting models have been widely used for decision-making in production, finance and energy. Such is the case of the ARIMA models, developed in the 1970s by George Box and Gwilym Jenkins [1], which incorporate characteristics of the past models of the same series, according to their autocorrelation. This work compares advanced statistical methods for determining the demand for electricity in Colombia, including the SARIMA, econometric and Bayesian methods.</p>

<p>Eating disorders are among the most common clinical manifestations in children, and they are frequently connected with maternal psychopathological risk, internalizing/externalizing problems in children, and poor quality of mother–child feeding exchanges. During the COVID-19 lockdown, in person assessment and intervention were impeded due to the indications of maintaining interpersonal distancing and by limits to travel. Therefore, web-based methods were adopted to meet patients’ needs. In this study N = 278 participants completed the SCL-90/R and the CBCL to examine the psychopathological symptoms of mothers and children (age of the children = 24 months); moreover, the dyads were video-recorded during feeding and followed an online video-feedback based intervention. Maternal emotional state, interactive conflict, food refusal in children, and dyadic affective state all improved considerably, as did offspring internalizing/externalizing problems and mothers’ depression, anxiety, and obsession–compulsion symptoms. This study showed that video-feedback web-based intervention might be employed successfully to yield considerable beneficial effects. © 2022 by the authors. Licensee MDPI, Basel, Switzerland.</p>

<p>Objetivo Estimar la asociación entre la maloclusión y el trastorno temporomandibular (TTM) con la cervicalgia en los pacientes que asistían al área odontológica de una clínica de Odontología. Materiales y métodos Se realizó un estudio de corte transversal en Lima, Perú. La población fue conformada por pacientes que asistían a una clínica odontológica, a quienes se evaluó el autorreporte de cervicalgia en los últimos 3 meses, el TTM con el índice de Fonseca, los tipos de maloclusión con la evaluación odontológica registrada en su historia clínica, así como hábitos orales y falta de piezas dentarias. Se evaluó la asociación calculando las razones de prevalencia ajustadas (RPa). Resultados Se incluyó a 215 personas, cuya edad media ± desviación estándar fue de 33,1±12,4 años y la mayoría fueron mujeres (69,3%). La prevalencia de cervicalgia fue del 64,2; el 79,1% tuvo algún grado de TTM y el 97,7% maloclusión. Tener TTM estuvo asociado a cervicalgia, tanto moderada como severa (RPa: 6,65; IC del 95%, 3,17-13,95), como leve (RPa: 4,88; IC del 95%, 2,29-10,41). No se halló asociación entre maloclusión y cervicalgia (RPa: 0,89; IC del 95%, 0,71-1,13). Otro factor asociado fue la ausencia de 3 o más dientes (RPa: 1,25; IC del 95%, 1,01-1,56). Conclusiones La cervicalgia está asociada al TTM pero no a la maloclusión, por lo que se recomienda un trabajo coordinado entre odontólogos y fisioterapeutas en el manejo de la TTM y cervicalgia para tratar integralmente a estos pacientes.</p>

<p>Aim: To evaluate the association between elevated serum transaminase levels and insulin resistance (IR) in a population of healthy individuals. Methods: We define IR with a cut-off point of homeostatic model assessment (HOMA-IR) ≥ 3.8. For aspartate aminotransferase (AST), we consider elevated values >30 U/L in women and values >36 U/L in men. For alanine aminotransferase (ALT), we consider elevated values >30 U/L in women and values >40 U/L in men. We performed a crude and adjusted generalized linear model from Poisson family with robust variance, in order to evaluate the association between elevated serum transaminase levels and IR. The associations were presented as prevalence ratio (PR) with their respective 95% confidence intervals (95% CI). Results: We included 261 participants in the study. The median age was 39 years (31–45) and 23.7% of the participants were men. The prevalence of elevated serum transaminase for AST and ALT were, 13.8% and 26.1%, respectively. The prevalence of IR was 34.1%. In the crude analysis we found statistical significance between elevated AST and ALT with IR (PR = 3.18; 95% CI: 2.33–4.34 and PR = 2.44; 95% CI: 1.88–3.30; respectively). However, in the multivariate analysis, the association only remained statistically significance with ALT, but lost its significance with AST, PR = 1.90; CI 95%: 1.31–2.77 and a PR = 1.23; CI 95%: 0.93–1.61; respectively. Conclusion: Elevated serum levels of ALT were associated with insulin resistance. ALT could be used in clinical practice as an additional tool to assess IR in apparently healthy people.</p>

<p>Fasciola hepática es un parásito de la clase Trematoda común en países en desarrollo. La infección en el ser humano se caracteriza por la triada de fiebre, dolor abdominal en el cuadrante superior derecho y eosinofilia. Se presenta el caso de una mujer de 67 años procedente de una zona rural al norte de Lima, con historia de dolor abdominal de seis meses de evolución, con una imagen hipodensa hepática en el TAC abdominal y eosinofilia. La biopsia hepática mostró un infiltrado inflamatorio con eosinofilia. En el diagnóstico diferencial en pacientes con un tumor hepático y eosinofilia, se deben incluir infecciones parasitarias como F. hepatica; sobre todo en pacientes que proceden de áreas endémicas.</p>

<p>The purpose of this paper is to present a maintenance study focused on total productive maintenance (TPM) and reliability-centered maintenance (RCM). Its approach is based on the first pillars of TPM, preventive and autonomous maintenance, as well as the FMEA analysis of RCM for maintenance analysis, which was conducted in this study. The implementation of TPM was successful in that various preventive maintenance (PM) policies assigned to the assets were implemented and it was demonstrated that TPM application in the construction industry could reduce the excessive accumulation of maintenance with the same effective optimization, and with support from RCM analysis and its heavy equipment systems analysis. Excessive corrective maintenance accounts for high investment and delay rates in work times of the assigned project. Traditional methods of availability guarantee, such as reactive or routine maintenance, are insufficient to satisfy a heavy equipment maintenance plan; therefore, what is called for is the systematic application of RCM and TMP because they allow the selection and application of effective PM tasks. An approach that develops and thoroughly analyzes the strategies of continuous corrective and PM is used with an atmosphere of uncertainty and with operational data limited by criticism. Results show a 90% improvement in availability.</p>

<p>This paper analyses three aspects of the share market operated by the Lima Stock Exchange: (i) the short-term relationship between the pricing, direction and volume of order flows; (ii) the components of the spread and the equilibrium point of the limit order book per share, and (iii) the pricing, order direction and trading volume dynamic resulting from shocks in the same variables when lagged. The econometric results for intraday data from 2012 show that the short-run dynamic of the most and least liquid shares in the General Index of the Lima Stock Exchange is explained by the direction of order flow, whose price impact is temporary in both cases.</p>

<p>Objective: To evaluate changes in physical performance in institutionalized older adults through a program of physiotherapy exercises. Materials and methods: We conducted a quasi-experimental study in adults over 60 years institutionalized in Lima, Peru. The exercise program was implemented in 45 minutes sessions included warming, muscle strengthening exercises, balance, gait training and cooling phase, three times a week for 12 weeks. Physical performance was measured with the Short Physical Performance Battery (SPPB) one week before and after the intervention. It included 45 participants, which 16 didn’t attend any of the sessions and was like control group. Results: The average age was 77.6±7.1 years, 62.2% were women. The mean baseline SPPB was 7.0±1.6 in the intervention group and 6.9±1.9 in the control group (p = 0.90). It shows a change in SPPB of 2.6±1.8 in the intervention group versus -1.4±2.0 in the control group (p<0.001). Conclusions: The development of a physiotherapy exercise program for institutionalized elderly increases physical performance, which could be implemented in care centers for elderly.</p>

<p>Objective: To compare condylar dimensions of young adults with Class II and Class III skeletal patterns using cone-beam computed tomography (CBCT). Materials and methods: 124 CBCTs from 18-30 year-old patients, divided into 2 groups according to skeletal patterns (Class II and Class III) were evaluated. Skeletal patterns were classified by measuring the ANB angle of each patient. The anteroposterior diameter (A and P) of the right and left mandibular condyle was assessed from a sagittal view by a line drawn from point A (anterior) to P (posterior). The coronal plane allowed the evaluation of the medio-lateral diameter by drawing a line from point M (medium) to L (lateral); all distances were measured in mm. Results: In Class II the A-P diameter was 9.06±1.33 and 8.86±1.56 for the right and left condyles respectively, in Class III these values were 8.71±1.2 and 8.84±1.42. In Class II the M-L diameter was 17.94±2.68 and 17.67±2.44 for the right and left condyles respectively, in Class III these values were 19.16±2.75 and 19.16±2.54. Conclusion: Class III M-L dimensions showed higher values than Class II, whereas these differences were minimal in A-P.</p>

<p>In the present study, an analysis of plain and reinforced concrete beams under monotonic loading was made based on the Fixed Smeared Crack approach. The objectives of this research were to analyze the nonlinear behavior of the selected cases of analysis and to propose an alternative and simple model for the analysis of beams under service loadings, by means of Committee 435 of the American Concrete Institute. A brittle model for concrete and a linear-elastic behavior for steel reinforcement bars were considered. Results are presented through force-displacement curves and the sequence of cracking propagation. Also, a comparison of calculated instantaneous deflections of simply supported beams was made between the proposed model and other researches. It was verified that the proposed algorithm can predict adequately the cracking process and the deflections of beams subjected to service loadings, taking into account experimental results from other authors.</p>

<p>Introduction: Health professionals performing their social health service (SHS) in rural communities could be at risk of developing depression. Moreover, those who migrate from farther places to perform their SHS could have an increased risk. The objective of this study was to evaluate the association between place of origin and the presence of depressive symptoms, in health professionals performing rural social health service (SHS) in Ancash, Peru. Methods: This was a cross-sectional study. During April 2015, a survey was applied to health professionals performing SHS in the Peruvian Ministry of Health (MINSA) facilities in Ancash. The main outcome was the presence of depressive symptoms, defined as a score =2 points in the Patient Health Questionnaire-2. The main exposure was the place of origin, defined as the place where the subjects completed their undergraduate professional studies (Ancash, Lima city or others). Poisson regressions with robust variance were performed to calculate crude and adjusted prevalence ratios (PR and aPR) and their 95% confidence interval (95%CI). Results: From 573 health professionals performing their SHS in MINSA in Ancash, 347 were included in the study. The mean age was 27.2±4.5 years, 78.7% were women, and 14.7% scored positive for depressive symptoms. Those who had completed their undergraduate professional studies in Lima city had a higher prevalence of presence of depressive symptoms compared to those who did in Ancash (aPR=2.59, 95%CI=1.23-5.45). Conclusions: Those who completed their undergraduate professional studies in Lima had a higher prevalence of depressive symptoms than those who did in Ancash. Possible explanations include the difficulty in visiting family and friends, acculturation, and lack of Quechua language proficiency.</p>

<p>In large urbanized cities, a major problem that affects the economy and health of all citizens is vehicular congestion. This is because the traffic light cycles are not adequate. In the present study, we seek to optimize traffic light cycles based on simulation, in order to improve vehicle flow. For this, the PTV Vissim 9.0 software was used as a simulator and the Synchro 10.0 software to determine the initial optimal traffic light cycle. Through several runs and having as variables the length of queues, delay times and the average speed, the optimal traffic light cycle could be found for the study area. The results obtained reflect a 14% reduction in delay times and 10% in queue lengths. On the other hand, the average vehicle speed increased by 10.56%. All this represents an improvement in the service level of the study intersections.</p>

<p>By the late 40's, the political scenario of the Second World War was mainly characterized by the high necessity to establish diplomatic relationships between the Axis and Allies powers. Within this framework, the Nuremberg trials were the scenario where simultaneous interpreting emerged. Since then, this industry has flourished differently around the world. In Peru, not many studies have been carried out on this professional activity. Therefore, the aim of this paper is to explore the employability process of interpreters in the Peruvian market. The researchers carried out eighteen interviews that explore the testimonies of interpreting graduates from two Peruvian universities: Universidad Ricardo Palma (URP) and Universidad Femenina del Sagrado Corazón (UNIFE). This paper was able to demonstrate that a successful job placement in the interpretation market depends on the appropriate management of soft skills, i.e. the effective use of contact networks, as well as technical and management skills.</p>

<p>This research includes the potential for resistance and the expansion that the soil presents, this evaluation was carried out through CBR tests. The soil cement technique was used to improve the physical and mechanical characteristics; this process consists in mixing the material with Portland cement type I. That combination forms soil cement 10%, 15% y 20%, which present an increase of the CBR (max: 138.7% and min: 91.9%) achieving a type of extraordinary subgrade to resist the structure of the pavement and a reduction of 7.18% in the expansion of the samples.</p>

<p>Con el objetivo de evaluar si existe asociación entre la mala calidad de sueño y la adherencia al tratamiento antirretroviral de gran actividad (TARGA) en personas con infección por VIH/ SIDA; llevamos a cabo un estudio analítico de corte transversal que incluyó 389 pacientes peruanos en TARGA. La mala calidad de sueño fue medida con la Escala de Calidad de Sueño de Pittsburgh y la adherencia con el CEAT-VIH. Realizamos un modelo lineal generalizado de familia Poisson, con errores estándar robustos para estimar razones de prevalencia y su IC95%. A nivel crudo la mala calidad de sueño leve, moderada y severa se asoció a la adherencia inadecuada. Al ajustar por las variables asociadas en el análisis bivariado o por las variables teóricamente asociadas a la adherencia, sólo la mala calidad de sueño moderada/severa se mantuvo asociada (RP = 1,34; IC95%: 1,17-1,54 y RP = 1,34; IC95%: 1,16-1,57; respectivamente). Se concluye que la mala calidad de sueño moderada/severa se asocia de manera independiente con la adherencia al TARGA. La evaluación de la calidad de sueño podría por ende ser útil en la valoración integral de los pacientes con VIH.</p>

<p>Objectives. To assess obesity risk among mothers participating in Community Kitchens and children participating in Glass of Milk (Peru food assistance programs). Methods. We analyzed prospective data from the Young Lives study. The exposure consisted in varying degrees of benefit from any of the programs (no participation in any of the programs, program participation for some months, or program participation nearly every month) at baseline (2006–2007). The outcome was overweight and obesity in mothers and children at follow-up (2009–2010). Results. Prevalence of childhood overweight and obesity was 15.5% and 5.1%, respectively; the corresponding figures for mothers were 40.5% and 14.6%. Children exposed nearly every month to the Glass of Milk program had a 65% lower risk of becoming obese compared with children not participating in the program (relative risk [RR] = 0.35; 95% confidence interval [CI] = 0.18, 0.66). Mothers participating frequently in the Community Kitchens program had almost twice the risk of becoming obese compared with those who did not participate (RR = 1.93; 95% CI = 1.18, 3.15). Conclusions. Participating in food assistance programs in Peru was associated with a lower risk of obesity in children and greater risk of obesity in mothers.</p>

<p>Introducción. La propagación de la COVID-19, una enfermedad infecciosa causada por el nuevo coronavirus SARS-CoV-2, se ha convertido en una pandemia que, a la par de su rápida diseminación a nivel mundial, ha traído consigo un aumento exponencial de la cantidad de estudios relacionados con el tema, fenómeno en el que los investigadores de Latinoamérica han participado activamente. Objetivo. Llevar a cabo un estudio bibliométrico descriptivo para identificar las tendencias de la investigación sobre COVID-19 producida en Latinoamérica. Materiales y métodos. Se recurrió a las bases de datos Web of Science, Scopus y Pubmed para recuperar la producción científica latinoamericana sobre COVID-19. Se analizaron los indicadores bibliométricos de producción, visibilidad, impacto y colaboración para evaluar la participación regional en la investigación sobre el tema. Resultados. El análisis de 142 documentos evidenció un crecimiento exponencial de la producción científica en el corto periodo analizado, una significativa colaboración internacional (51,4 %), y el liderazgo de las instituciones regionales (71 %) en la investigación con aportes en revistas de alta visibilidad, especialmente de Colombia, Brasil y México. Conclusiones. El estudio evidenció resultados relevantes sobre la participación regional en la investigación sobre COVID-19, no solo en cuanto a la cantidad y el crecimiento exponencial, sino también a su calidad y excelencia, con una elevada tasa de colaboración internacional y de publicación en revistas de reconocido prestigio, lo que, además de ser clave para la visibilidad de los países, es un considerable aporte a las investigaciones que se realizan en otros contextos geográficos.</p>

<p>La pancreatitis aguda por hipercalcemia secundaria a hiperparatiroidismo primario es una etiología infrecuente. Presentamos una paciente mujer de 77 años que presentó dolor abdominal en hemiabdomen superior y vómitos; colecistectomizada, no bebe alcohol ni presenta dislipidemia. Los estudios de laboratorio mostraron, amilasa de 394 U/L y lipasa de 906 U/L, calcio sérico 17,93 mg/dL y el PTHi 441 pg/ml. En la TEM de cuello, se observó bocio multinodular (nódulos de 9 y 7 mm) en el lóbulo izquierdo de tiroides y un nódulo en paratiroides. La paciente fue sometida a una paratiroidectomía superior derecha y una hemitiroidectomía del mismo lado. Después de la cirugía, los niveles de Ca sérico y PTHi disminuyeron. Asimismo, como hallazgo en la biopsia, se encontró carcinoma papilar variante folicular de tiroides. Este reporte explica las posibles teorías de asociación entre adenoma paratiroideo y pancreatitis por hipercalcemia y describe además la asociación con carcinoma papilar variante folicular de tiroides, no antes descrito.</p>

<p>This study aims to design and validate a nutritional recipe for a snack made of Green Banana (Musa paradisiaca) Peel Flour (GBPF) and to assess the nutritional composition and microbiological quality of the flour. Banana peel, a food industry by-product, is a nutritious, low-cost material available for all year. Banana peel flower could be used as a functional ingredient due to its high fiber content and good functional properties. In general, university students have a deficient dietary fiber intake due to altered dietary patterns; thus, this study was focused on this population. The GBPFs were obtained from the peels of pre-climacteric bananas by fluidized bed (FDB) dryer, after which, microbiological, proximate, and dietary fiber analyses were applied. It was designed the nutritional recipe for the snack taking into account the energy and dietary fiber nutritional requirements of the target population. It could be validated and adjusted the recipe following the methodology of Centro Nacional de Alimentaci n y Nutrici n, concluding with the determination of dietary fiber in the end-product. The dietary fiber, total carbohydrate, protein, total fat and energy contents of the GBPF were as following: 38.7 g, 76.3 g, 5.9 g, 3.6 g, and 361.2 kcal, per 100 g of flour. The snack contained 7.74 g of dietary fiber per serving size, having a good acceptance among the university students' panelists based on an organoleptic test. In conclusion, the GBPF showed great potential as a source of dietary fiber, and it was an excellent source of carbohydrates and other nutrients to a lesser degree. When included as a functional ingredient in the nutritional formulation of a snack, it had an overall positive effect on the product's organoleptic characteristics.</p>

<p>In this review, we discuss considerations and successful models for providing decentralized diagnosis, treatment, and prevention services for children and adolescents. Key approaches to building decentralized capacity for childhood TB diagnosis in primary care facilities include provider training and increased access to child-focused diagnostic tools and techniques. Treatment of TB disease should be managed close to where patients live; pediatric formulations of both first-and second-line drugs should be widely available; and any hospitalization should be for as brief a period as medically indicated. TB preventive treatment for child and adolescent contacts must be greatly expanded, which will require home visits to identify contacts, building capacity to rule out TB, and adoption of shorter preventive regimens. Decentralization of TB services should involve the private sector, with collaborations outside the TB program in order to reach children and adolescents where they first enter the health care system. The impact of decentralization will be maximized if programs are family-centered and designed around responding to the needs of children and adolescents affected by TB, as well as their families.</p>

<p><strong>RESÚMEN:</strong></p>
<p>La presente investigación teórica se ubica en el campo de la Psicología de la Religión y la Espiritualidad. Sus objetivos son analizar la formación que recibe el estudiante de psicología en este campo y las actitudes del docente encargado de su formación. Se reporta que de acuerdo a las investigaciones, la dimensión religiosa y espiritual es crucial en el desarrollo de la persona, por lo que se plantea la urgencia que los futuros psicólogos estén preparados para conocer cómo afectan variables como la fe en Dios, el bienestar espiritual, las creencias, convicciones y necesidades espirituales, estilos de afrontamiento, entre otros, al ser humano. Dado que la mayoría de las universidades latinoamericanas no brindan cursos de formación vinculados a este campo, se sugiere la revisión de las mallas curriculares para identificar los vacíos en la formación e incorporar cursos que permitan a los futuros psicólogos el cumplimiento cabal de sus funciones.</p>
<p> </p>
<p><strong>DESCRIPCIÓN :</strong></p>
<p>This theoretical research is positioned within the field of Psychology of Religion and Spirituality. Its goals are to analyze the training received by psychology students in this field, as well as the attitudes of the instructors in charge of such training. Based on research, it is reported that the religious and spiritual dimension is critical in an individual’s development; consequently, it is of outmost importance that future psychologists be prepared to understand the way such variables as faith in God, spiritual well-being, beliefs, convictions and needs, and coping styles, among others, affect the human being. Since most Latin American universities do not offer training courses related to this field, a revision of curricula is suggested, so as to identify gaps in such training and include courses that will enable future psychologists to fully perform their duties.</p>

<p>Mucinous adenocarcinoma of the appendix is a rare neoplasm with an incidence rate of 0.08% of all malignancies. The diagnosis is usually made by biopsy because its clinical presentation may mimic other diseases of structures located in the right lower quadrant. Currently, the treatment is still controversial, being surgery the best option. This report describes a patient with a history of appendectomy 27 years ago that is hospitalized for a painful mass in the lower abdomen associated with carcinoembryonic antigen of 138 ng/dl.</p>

<p>Introduction: The high transmissibility and lethality of the novel coronavirus SARS-CoV-2 (COVID-19) have been catastrophic. Acute kidney injury (AKI) is one of the frequent complications in patients with respiratory insufficiency caused by the virus. The pathogenic mechanism is based on the binding of its S-proteins to the angiotensin-converting enzyme (ACE) receptors, which will trigger a cellular damage. A podocyte and tubular compromise are found in the kidneys which can lead to tubular necrosis and the consequent AKI. Objectives: The objective of this report is to identify the main risk factor to develop AKI in patients infected with SARS-CoV-2 with critical acute respiratory distress. Patients and Methods: We performed this report study, collecting data from 48 ICU patients. Data from 13 of them who developed AKI and needed renal replacement therapy (RRT)were analyzed. Clinical characteristics and laboratory findings were reported using STATA 10.0. Results: AKI was present in 27.08% of patients, mostly male (92.3%) with a mean age of 63.8 years old. Hypertension, diabetes and obesity were the main comorbidities in those patients. Additionally, the meantime between admission and AKI diagnosis was 2.69 days. All patients showed fibrinogen, D-dimer, ALT and values above normal range. Mortality was seen in 61.5% of patients. Conclusion: This report tries to show AKI as an important clinical manifestation in critically ill patients infected with SARS-CoV-2, with high mortality. Further studies are needed to demonstrate if there are independent risk factors.</p>

<p>Currently, there is a large percentage of small and medium-sized enterprises (SMEs) in the Peruvian textile market that show economic loss because of the payment of penalties to customers, which are incurred owing to the delay in the delivery of order batches. This is due to poor production management and a lack of focus. The manufacturing sector is essential because of its high contribution to the country's gross domestic product. Currently, SMEs do not employ methodologies that help improve production and process management as they do not realize how important and necessary the methodologies are, in addition to how complex these may be. Therefore, this paper will propose a production management model designed for SMEs in this sector, based on Lean methodology where the objective is time reductions and production increases as well as exerting changes to the organizational culture. Thus, this model will help organizations to avoid incurring economic losses because of the payment of penalties for orders not delivered on time. To validate the present model, a time simulation was performed in the manufacturing area of a textile company. The result of this project was positive, since there was a 25% increase in productivity and a 20% reduction of takt time with respect to the initial data.</p>

<p>Objectives. We aimed to assess if Caesarean section is a risk factor for overnutrition in early- and late-childhood, and to assess the magnitude of the effect of child- versus family-related variables in these risk estimates. Methods. Longitudinal data from Peruvian children from the Young Lives Study was used. Outcomes assessed were overweight, obesity, overnutrition (overweight plus obesity), and central obesity (waist circumference) at the age 5 (first follow-up) and 7 (second follow-up) years. The exposure of interests was delivery by Caesarean section. Relative risks (RR) and 95% confidence intervals (95% CI) were calculated using multivariable models adjusted for child-related (e.g., birth weight) and familyrelated (e.g., maternal nutritional status) variables. Results. At baseline, mean age was 11.7 (± 3.5) months and 50.1% were boys. Children born by Caesarean section were 15.6%. The 10.5% of the children were overweight and 2.4% were obese. For the obesity outcome, data from 6,038 and 9,625 children-years was included from baseline to the first and second follow-up, respectively. Compared to those who did not experience Caesarean delivery, the risk of having obesity was higher in the group born by Caesarean: RRs were higher at early-childhood (first follow-up: 2.25; 95% CI [1.36–3.74]) than later in life (second follow-up: 1.57; 95% CI [1.02–2.41]). Family-related variables had a greater effect in attenuating the risk estimates for obesity at the first, than at the second follow-up. Conclusion. Our results suggest a higher probability of developing obesity, but not overweight, among children born by Caesarean section delivery. The magnitude of risk estimates decreased over time, and family-related variables had a stronger effect on the risk estimates at early-childhood.</p>

<p>Introduction: The COVID-19 pandemic has increased the magnitude of mental illnesses such as depression, not only in the general population, but also in healthcare personnel. However, in Peru the prevalence, and the associated factors for developing depression in healthcare personnel, are not known. The objective was to determine the prevalence and identify the factors associated with depression in healthcare personnel, in the context of the SARS-CoV-2 pandemic. Methods: An analytical cross-sectional study was carried out from May to September, 2020 in healthcare establishments. A sample of 136 health workers were included and a survey was applied to collect the data. Depression as a dependent variable was measured using the Zung self-report scale. To identify the associated factors, the bivariate and multivariate analysis was performed by logistic regression with STATA v 14. Results: The prevalence of depression was 8.8% (95%CI, 4.64-14.90). Having a family member or friend who had died from COVID-19 was associated with depression (OR = 6.78; 95%CI, 1.39-32.90; P = 0.017). Whereas the use of personal protective equipment was found to be a protective factor against developing depression (OR = 0.03; 95%CI, 0.004-0.32; P = 0.003). Conclusions: Approximately 1 in 10 healthcare professionals and technicians developed depression during the COVID-19 pandemic in this study. In addition, having relatives or friends who had died from COVID-19 was negatively associated with depression and use of personal protective equipment was identified as a protective factor.</p>

<p>Stem cell transplantation with rehabilitation therapy presents an effective stroke treatment. Here, we discuss current breakthroughs in stem cell research along with rehabilitation strategies that may have a synergistic outcome when combined together after stroke. Indeed, stem cell transplantation offers a promising new approach and may add to current rehabilitation therapies. By reviewing the pathophysiology of stroke and the mechanisms by which stem cells and rehabilitation attenuate this inflammatory process, we hypothesize that a combined therapy will provide better functional outcomes for patients. Using current preclinical data, we explore the prominent types of stem cells, the existing theories for stem cell repair, rehabilitation treatments inside the brain, rehabilitation modalities outside the brain, and evidence pertaining to the benefits of combined therapy. In this review article, we assess the advantages and disadvantages of using stem cell transplantation with rehabilitation to mitigate the devastating effects of stroke.</p>

<p>Este documento contiene el diseño de una estrategia para enseñar mapas perceptuales en un curso de gerencia de marca, con la adición de una técnica de modelado para elaborarlos. Los mapas perceptuales son herramientas para el análisis del posicionamiento de marca, y se enseñan en cursos de pregrado y postgrado. Sin embargo, es muy usual utilizar un marco puramente descriptivo y teórico, sin explicar los mecanismos para construirlos. Se presentan métodos basados en regresión multilineal y en análisis factorial como herramientas de modelado, para explicar en clase y proporcionar una mejor comprensión de esta materia.</p>

<p>Objective: To evaluate the association between self-reported bruxism and academic performance in students at a university in Lima, Peru. Material and Methods: A total of 203 students were evaluated in this study, between the ages of 19 and 35 years. Self-reported bruxism was measured using the Bruxism Assessment Questionnaire. Academic performance was evaluated using the Approval Index Scale. In addition, other variables were included such as employment status, socioeconomic level, stress, anxiety, among others. The association of variables were factored in using the chi-square test and the logistic regression presented the unadjusted and adjusted analisis. Results: The frequency of self-reported awake bruxism and sleep bruxism was 53.20% and 36.45%, respectively. Evidence revealed there was a statistically significant association between awake bruxism with stress and anxiety, and sleep bruxism with anxiety. Students with high academic performance (OR=2.36; IC del 95%:1.06-5.23) and low academic performance (OR=5.72; IC del 95%:1.28-25.57) were found to be more likely to have awake bruxism than those with medium academic performance. Conclusion: This study revealed a statistically significant association between self-reported awake bruxism and academic performance. However, in the future it is suggested to carry out a study with focus only on students with bruxism and with a larger sample of participants with low academic performance to confirm the association found between these variables.</p>

<p>As an alternative to lap splicing, mechanical splices can be used for retrofit purposes. They are generally most economical than traditional lap splices when available spacing or length makes laps difficult to utilize. Mechanical splices are frequently used in new construction. However, their use is limited and not practical for use in retrofitted structures. However, if the bars to be joined do not need to be threaded in order to be connected with a special mechanical splice, such mechanical splices can be useful. It is presented a proposal of using two types of mechanical splices for retrofit purposes. Cycle Tension and cycle tension-compression tests are presented and discussed. It was found that mechanical splices are suitable and have acceptable response under seismic loads.</p>

<p>Introduction: Diarrhea remains one of the main causes of morbidity and mortality in children under five years of age especially in low-income countries. In Peru, epidemiological reports about enteropathogens related to acute diarrhea are scarce in rural areas. The aim of this study was to describe the etiology, epidemiology, and clinical characteristics of the principal causes of acute infectious diarrhea in in a northern rural region of Peru. Methodology: A prospective study was conducted from January 2011 to December 2012 to describe the main pathogens causing acute diarrhea using PCR assay. Results: A total of 117 children diagnosed with acute diarrhea were included in the study. A single etiological agent was identified in 41.03% of samples, being rotavirus followed by norovirus and Shigella. Co-infections containing virus and bacteria were found in 22.22% of samples. Vomiting was most commonly found symptoms in 58.97% cases followed by fever (54.70%). Malnutrition was detected in 14.53% of the children. Conclusions: High prevalence of rotavirus, as well as adenovirus and norovirus, was observed in the present study. Shigella was the most common bacteria found in acute diarrhea in the area. The implementation of a better surveillance system is mandatory in order to identify the principal etiologies of gastroenteritis in the rural areas of Peru and to develop of better prevention strategies and reduce diarrhea-associated mortalities.</p>

<p>Background: Toxoplasmosis, caused by Toxoplasma gondii, is transmitted to humans in several ways, such as transplacental spread. It is estimated that this parasite infects a third of the world population and it is associated with congenital infection and fetal loss. Only 10 to 20% of the cases are symptomatic. Case report: We present the case of a pre-term newborn that had been referred to a tertiary care center. During the in-hospital period, diagnosis of congenital toxoplasmosis with many systemic manifestations was performed. Conclusions: Most cases of congenital toxoplasmosis are asymptomatic. Diagnosis tests and a complete physical examination should be performed on all newborns with suspicion of infection to detect all possible manifestations as in the case reported. © 2014 Hospital Infantil de México Federico Gómez.

<p>Los tumores mucosos apendiculares tienen baja incidencia y comúnmente se diagnostican en el estudio anatomo-patólogico después de la apendicectomía. Se reporta el caso de una mujer de 41 años de edad, con un cuadro clínico de ocho meses de evolución, caracterizado por dolor abdominal de tipo opresivo, difuso y de gran intensidad en el hemiabdomen inferior, acompañado de náuseas. Después de cinco meses de iniciado este cuadro clínico, se evidenció una masa en la fosa iliaca derecha; el dolor se agudizó e intensificó, y las náuseas continuaron, por lo cual fue remitida al hospital. En los exámenes practicados se observó una masa quística compleja abdomino-pélvica de origen indeterminado, y la tomografía computadorizada de abdomen fue sugestiva de mucocele apendicular. Con estos hallazgos, se optó por el tratamiento quirúrgico por laparotomía, consistente en hemicolectomía derecha, con resección parcial de íleon, epiplectomía, histerectomía y salpigooforectomía bilateral.</p>

<p>This investigation proposes a lean model of production management for a small and micro enterprise (SME) dealing in packaging production in the auto parts sector, with the purpose of increasing efficiency in its production line. To this end, this model integrates study method tools and SMED, seeking to reduce waiting times and unnecessary operations, which have been identified as causing the problem on the basis of an initial diagnosis of the situation. Furthermore, to support and guarantee success in implementing these tools, John Kotter's Change Model is used. After two months of implementation, the results showed a 50% reduction in setup operation time and a 32% decrease in filing operation time, which are bottlenecks in the production process. Thus, with the new indicators, the line efficiency increased by 7% from the initial situation, thus showing improvement.</p>

<p>Latin American experiences are analyzed in order to identify adverse factors, describing the complexity of the implementation of a Fabrication Laboratory in the region. As a starting point we take the implementation done by groups of academics coming back to their origin countries, and others that after the implementation they were born or adapted to an academic supervision (Fab Lab MIT) or a technical and commercial one (Rhino FabLab). In the whole, the results allow to identify opportunities for the future.</p>

<p>Introduction: This work responds to the need of developing digital skills in teachers, who can take advantage of the different potentialities of technological resources in order to achieve better learning in their students. Objective: To determine the differences between the dimensions of the digital competence of teachers of the School of Health Sciences of a private university in Lima, Peru, according to sociodemographic variables. Methods: A comparative descriptive design was used. It should also be noted that a total population composed of 40 teachers was considered, of which 34 agreed to collaborate in the research. The instrument used to collect information was an adaptation of the Teaching Digital Competence Questionnaire, prepared by Javier Tourón, Deborah Martín, Enrique Navarro, Silvia Pradas and Victoria Íñigo in 2018. In addition, a sociodemographic record was addressed to teachers. Subsequently, statistical analysis was performed using the SPSS 25 software. Results: It was found that there were no significant differences between the dimensions of digital competence, according to the sociodemographic variables of sex, age, maximum level of study reached, and years of teaching experience. Even so, the differences evidenced in some of these variables could be subject of future studies. Conclusions: The dimension in which teachers have the greatest problems is security, while the one in which they have the least difficulties is problem solving.</p>

<p>Objectives: To explore salt content in bread and to evaluate the feasibility of reducing salt contained in ‘pan francés’ bread. Design: The study had two phases. Phase 1, an exploratory phase, involved the estimation of salt contained in bread as well as a triangle taste test to establish the amount of salt to be reduced in ‘pan francés’ bread without detection by consumers. In Phase 2, a quasi-experimental, pre–post intervention study assessed the effects of the introduction of low-salt bread on bakery sales. Setting: A municipal bakery in Miraflores, Lima, Peru. Subjects: Sixty-five clients of the bakery in Phase 1 of the study; sales to usual costumers in Phase 2. Results: On average, there was 1·25 g of salt per 100 g of bread. Sixty-five consumers were enrolled in the triangle taste test: fifty-four (83·1 %) females, mean age 58·9 (SD 13·7) years. Based on taste, bread samples prepared with salt reductions of 10 % (P = 0·82) and 20 % (P =0·37) were not discernible from regular bread. The introduction of bread with 20 % of salt reduction, which contained 1 g of salt per 100 g of bread, did not change sales of ‘pan francés’ (P=0·70) or other types of bread (P =0·36). Results were consistent when using different statistical techniques. Conclusions: The introduction of bread with a 20 % reduction in salt is feasible without affecting taste or bakery sales. Results suggest that these interventions are easily implementable, with the potential to contribute to larger sodium reduction strategies impacting the population’s cardiovascular health.</p>

<p>En el presente artículo damos cuenta de una experiencia de enseñanza-aprenizaje en el taller inicial de Traducción Directa 1 Inglés del program,a de pregrado en traducción de la Universidad Peruana de Ciencias Aplciadas. Nos basanmos en la manera en que el taller integró temáticas de género en su diseño instruccional mediante la revisón de las competencias que el taller pretende desarrollar, asi como la adapatación de los textos y las actividades de traducción regulares. Presentaremos las principales estrategías que se desarrollaron en el pkanteamiento y la ejecución del taller. El artículo expone inicialmente el contexto político del perú en 2016, cuando surgió la iniciativa de amoldar el taller mediante temas de género y del que se deriva el objetivo principal del estudio. Las secciones de análisis parten de la descripción del taller en cuestión para abordar (1) las competencias de traducción, los logos de aprendizaje y su vínculo potencial con la investigación formativa en la que se integra el tema de género, (2) la selección de texto fuente y los criterios para el diseño de actividades de aprendizaje. Finalmente presentamos un baolance sobre la efectividad de rediseño del taller mediante la inclusión de temas de género y las percepciones docentes y discentes que resultaron de la experiencia.</p>
