ABSTRACT Introduction: This article summarizes the clinical practice guide (CPG) for the surgical management of obesity in adults in the Social Security of Peru (EsSalud). Objective: To provide clinical recommendations based on evidence for the surgical management of patients with obesity in EsSalud. Methods: A CPG for the surgical managmente of patients with obesity in EsSalud was developed. To this end, a guideline development group (local GDG) was established, including medical specialists and methodologists. The local GDG formulated 7 clinical questions to be answered by this CPG. Systematic searches of systematic reviews and -when it was considered pertinent- primary studies were conducted in Medline and CENTRAL during 2019. The evidence to answer each of the posed clinical questions was selected. The quality of the evidence was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology. In periodic work meetings, the local GDG used the GRADE methodology to review the evidence and formulate the recommendations, points of good clinical practice, and the flowchart identification of patients with indication for bariatric / metabolic surgery and selection of the type of surgical intervention. The flowchart was designed in the final phase or last meeting based on the recommendations made previously. Finally, the CPG was approved with Resolution No. 115 - IETSI - ESSALUD - 2020. Results: This CPG addressed 7 clinical questions, divided into topics of surgical management of patients with obesity. Based on these questions, 6 recommendations were formulated (3 strong and 3 conditional), 18 BPC, and 2 flow charts. Conclusion: This article summarizes the methodology, recommendations based on evidence, and the points of good clinical practice from the CPG for the surgical management of obesity in EsSalud.

ABSTRACT Objective: To describe the prevention and control practices for the infection to SARS-COV2 in the Peruvian population. Methods: Observational descriptive study. We evaluated a non-probabilistic sample of adult residents in some departments of Peru. Preventive practices were evaluated in people without a history of COVID-19 and control practices in people who had suffered it. Results: We evaluated 3630 Peruvians (mean age 25.4 ± 9.5), of that 3231 don’t have a history of COVID-19 and 399 who had suffered it. The prevention and control practices that were realized often or always, with more frequencies, was the use of a mask when they go out home (97.9% vs 87.7), cover their nose or mouth when they sneeze (95.4% vs 89.9%), save the distance to other people in the street (91.4% vs 74.7%), wash their hands when they came home (92.5% vs 88.7%), and disinfect the objects and personal places (82.6% vs 77.4%). The 22.1% and 83.7%, the 59.7% and 80.2, and the 8.0% and 16.8% consumed some type of medicine, medicinal plant, and chlorine dioxide to prevent and control the infection, respectively. Conclusion In general, less than 50% of the participants performed prevention and control practices against COVID-19 often or always.

RESUMEN Introducción: Los médicos residentes que laboran más horas diarias son propensos a sufrir problemas de salud mental como la depresión, tema que se ha estudiado poco. Por ello, el presente estudio tiene por objetivos determinar la prevalencia de los síntomas depresivos y evaluar la asociación entre el número de horas diarias laboradas y la presencia de síntomas depresivos en residentes del Perú. Métodos: Estudio transversal analítico que usó la base de datos de la Encuesta Nacional para Médicos Residentes-2016, una encuesta voluntaria realizada virtualmente por el Consejo Nacional de Residentado Médico de Perú a médicos que realizaban su residencia en este país. Se consideró presencia de síntomas depresivos una puntuación ≥ 3 con la escala Patient Health Questionnaire-2. Las horas laboradas diariamente se tomaron mediante una pregunta directa. Para evaluar la asociación de interés, se calcularon razones de prevalencia (RP) y sus intervalos de confianza del 95% (IC95%) usando regresiones de Poisson brutas y ajustadas con varianza robusta. Resultados: Se evaluaron las respuestas de 953 residentes (el 41,3% mujeres; media de edad, 32,5 arios), de los que el 14,6% tenía síntomas depresivos. En el análisis ajustado, se encontró que la prevalencia de síntomas depresivos aumentaba por cada hora laborada adicional (RP = 1,11; IC95%, 1,04-1,17). Conclusiones: Uno de cada 7 residentes presentó síntomas depresivos. Por cada hora laborada diariamente extra, la frecuencia de síntomas depresivos aumentó un 11%.

ABSTRACT Introduction: Resident physicians who work more hours a day are prone to suffer mental health problems such as depression, a subject that has been little studied. In this regard, the aim of this study was to determine the prevalence of depressive symptoms and to evaluate the association between the number of daily working hours and depressive symptoms in Peruvian residents. Methods: Analytical cross-sectional study that used the database of the National Survey for Resident Physicians-2016, a voluntary survey issued virtually by the National Council of Medical Residency of Peru to physicians who were undertaking their residency in Peru. The presence of depressive symptoms was considered as having obtained a score ≥3 with the Patient Health Questionnaire-2 scale. The number of hours worked each day was collected through a direct question. To assess the association of interest, prevalence ratios (PR) and their 95% confidence intervals (95% CI) were calculated using crude and adjusted Poisson regressions with robust variance. Results: The responses of 953 residents (41.3% women, mean age: 32.5 years) were evaluated, 14.6% of which presented depressive symptoms. In the adjusted analysis, it was found that the prevalence of depressive symptoms increased for each additional hour worked (PR = 1.11; 95% CI, 1.04-1.17). Conclusions: One in seven residents had depressive symptoms. For every extra daily working hour, the frequency of depressive symptoms increased by 11%.

ABSTRACT This paper summarizes the evidence-based clinical recommendations for the assessment and management of patients with acute lymphoblastic leukemia (ALL) in Peruvian Social Security (EsSalud). A guide writing team (GWT) was convened, which included specialized physicians and methodologists. The GWT asked 8 clinical questions to be responded by the Clinical Practice Guidelines (CPG). Detailed searches of systematic reviews and - when it was considered as pertinent - primary studied featured in PubMed and CENTRAL during 2019 were performed. Evidence for responding each of the proposed clinical questions was selected. Certainty of the evidence was determined using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology. In scheduled workshops, the GWT used the GRADE methodology for reviewing the evidence and propose recommendations, the points for good clinical practice, and the assessment and management flowcharts. This CPG worked on 8 clinical questions, which were divided in 4 topics: diagnosis, general measures, chemotherapy management for ALL, and transplantation. On the basis of these questions, 5 recommendations were formulated (3 strong recommendations and 2 conditional recommendations), 20 points for good clinical practice, and 3 flow charts.

RESUMO: Objetivo: Determinar a associação entre a discriminação percebida e o recebimento de tratamento adequado para doenças crônicas em migrantes venezuelanos. Métodos: Foi realizado um estudo transversal. Esta é uma análise secundária da pesquisa nacional Venezuelan Population Residing in the Country Survey do Peru. A associação entre discriminação percebida e receber tratamento adequado para doenças crônicas foi avaliada por meio de um modelo de regressão de Poisson, considerando o efeito ajustado da amostra em múltiplos estágios. Resultados: Foram avaliados 865 migrantes (idade: 36,6 ± 0,7 anos e 58,2% mulheres). Destes, 54,8% perceberam discriminação e 89,2% não receberam tratamento para a doença crônica. A discriminação percebida foi significativamente associada à menor prevalência de receber adequado tratamento para doenças crônicas (razão de prevalência ajustada — RPa = 0,49, intervalo de confiança de 95% — IC95% 0,25 – 0,97). Conclusão: Este estudo mostrou que a discriminação percebida diminui a prevalência de receber adequado tratamento para doenças crônicas em 50%, em comparação com aqueles que não percebem a discriminação.

ABSTRACT: Objective: To determine the association between perceived discrimination and receiving adequate treatment for chronic diseases in Venezuelan migrants. Methodology: A cross-sectional study was performed. This is a secondary analysis of the ENPOVE national survey from Peru. The association between the perceived discrimination and receiving adequate treatment for chronic diseases was evaluated using a Poisson regression model, considering the adjusted effect of the multistage sampling. Results: A total of 865 migrants were evaluated (age: 36.6 ± 0.7 years and 58.2% women). Of these, 54.8% perceived discrimination, and 89.2% did not receive adequate treatment for chronic diseases. Perceived discrimination was significantly associated with a lower prevalence of receiving adequate treatment for chronic diseases (PRa = 0.49; 95%CI 0.25 – 0.97). Conclusion: This study evidenced that perceived discrimination decreases the prevalence of receiving adequate treatment for chronic diseases by approximately 50% compared with those who did not perceive discrimination.

Abstract Lymphangioma is a rare and understudied pathology that is usually detected in the first decade of life, and its appearance in adults is rare. This report details a 51-year-old man with morbid obesity who presented, for the last eight months, multiple asymmetric tumor lesions with extension to the scrotal region. The diagnosis of circumscribed lymphangioma with associated infection was confirmed. This case report demonstrates an unusual presentation of the characteristics of the lymphangioma that are seldom described in the literature.

ABSTRACT Acute appendicitis is the most common pathology from acute abdomen during pregnancy, which has a difficult diagnosis because of the physiological changes during pregnancy which results in confusing clinical presentations. We reported the case of a multiparous woman of 27 years with 22 3/7 weeks diagnosed with acute appendicitis, undergoing surgery without complications and with a necrosed appendix that was evidenced through pathological examination. It is important to emphasis the role of the anamnesis with the physical examination guided by the physiological pregnancy changes related to the appendix. A timely diagnosis and treatment with an interdisciplinary approach would significantly reduce the maternal-fetal risks related to this pathology, the appendix removal and the continuation of the pregnancy.

RESUMEN La apendicitis aguda es una patología de abdomen agudo quirúrgico frecuente en el embarazo, siendo de difícil diagnóstico debido a los cambios fisiológicos del embarazo que ocasionan cuadros clínicos confusos. Reportamos el caso de una gran multigesta de 27 años de 22 semanas 3/7 en el cual se diagnosticó clínicamente apendicitis aguda, siendo intervenida quirúrgicamente sin complicaciones, encontrándose un apéndice necrosado corroborado posteriormente con anatomía patológica. Es importante enfatizar el rol de la anamnesis dirigida aunado al examen clínico orientado por los cambios fisiológicos del embarazo. Un diagnóstico oportuno junto al manejo interdisciplinario permitirá reducir significativamente los riesgos materno y fetales relacionados a esta patología, y tanto la extirpación del apéndice como la continuación del embarazo.

RESUMEN Introducción: El machismo está arraigado en ciertas poblaciones, pero no se ha medido esto entre los que se encargarán de la atención de la salud. Objetivo: Determinar los factores asociados con el machismo entre los estudiantes de Medicina de 12 universidades peruanas. Métodos: Estudio transversal analítico de tipo multicéntrico, con datos recogidos previamente, en el que se usaron tests validados para la medición del machismo y la religiosidad; además, se indagaron otras características sociales y educativas y se cruzaron los datos. Se obtuvieron estadísticos descriptivos y analíticos. Resultados: En el análisis multivariable, se encontró asociación entre ser machista y no creyente (RP = 1,88; IC95%, 1,47-2,40), así como ser mujer (RP = 0,35; IC95%, 0,27-0,46). De las 12 universidades evaluadas, la universidad menos machista fue una particular en Lima. Utilizando esta universidad como categoría de comparación, las universidades estadísticamente más machistas fueron una privada de Chiclayo (a=3,63; p < 0,001), seguida de una particular en Huancayo (a=3,20; p = 0,001), la nacional de Huancayo (a = 2,79; p < 0,001) y la pública de Ica (a = 2,32; p = 0,006); los cruces se ajustaron por la edad. Conclusiones: Se encontró que el machismo es mayor entre los no creyentes, los varones y en algunas universidades, con predominio de universidades de la sierra central del Perú o con migrantes de la serranía. Esto es importante, ya que brinda un panorama acerca de este rasgo de los que serán los futuros encargados de velar por la salud de los peruanos.

ABSTRACT Introduction: Male chauvinism is rooted in certain populations, but it has not been measured among those who will be responsible for healthcare. Objective: To determine the factors associated with male chauvinism among the medical students of 12 Peruvian universities. Methods: Cross-sectional multicentre analytical study, with previously collected data, which used validated tests to measure male chauvinism and strong religious beliefs. In addition, other social and educational factors were analysed and the data was crossed. Descriptive and analytical statistics were obtained. Results: In the multivariate analysis, we found an association between male chauvinism and religious non-believers (RP=1.88; 95% CI, 1.47-2.40), as well as being female (RP=0.35; 95% CI, 0.27-0.46). Of the 12 universities evaluated, the least chauvinistic university was in Lima. Using this university as a comparison category, the statistically more chauvinistic universities were a private university in Chiclayo (a=3.63; p<0.001), followed by a university in Huancayo (a=3.20; p=0.001), Huancayo national university (a=2.79; p<0.001) and the public university of Ica (a=2.32; p=0.006); the crossed data were adjusted for age. Conclusions: It was found that male chauvinism is greater among non-religious believers, men and in some universities, with a predominance of universities in the central highlands of Peru or that had migrants from the mountains. This is important, since it gives us an overview about this trait in those who will be responsible for the future healthcare of Peruvians.

RESUMEN Introducción: Las consecuencias de la homofobia pueden afectar a la integridad y la salud mental y física de los individuos homosexuales en la sociedad. En Perú hay escasos estudios que hayan evaluado la homofobia en la población médico-estudiantil. Objetivo: Determinar los factores sociales, educativos y culturales asociados con la homofobia entre estudiantes de Medicina peruanos. Métodos: Se realizó un estudio de tipo transversal analítico en 12 sedes de Medicina humana peruanas. Se definió homofobia según un test validado, que se asoció con otras variables. Se obtuvieron estadísticos de asociación. Resultados: Las 4 universidades de Lima obtuvieron menores porcentajes de alumnos homofóbicos (15-20%) que las universidades del interior del país (22-62%). Al realizar el análisis multivariable, disminuyeron la frecuencia de homofobia: ser mujer (RPa = 0,74; IC95%, 0,610,92; p = 0,005), estudiar en una universidad de Lima (RPa = 0,57; IC95%, 0,43-0,75; p < 0,001), profesar la religión católica (RPa = 0,53; IC95%, 0,37-0,76; p < 0,001), conocer a un homosexual (RPa = 0,73; IC95%, 0,60-0,90; p = 0,003) y haber atendido a un paciente homosexual (RPa = 0,76; IC95%, 0,59-0,98; p = 0,036); en cambio, ser machista aumentó la frecuencia de homofobia (RPa = 1,37; IC95%, 1,09-1,72; p = 0,007), ajustado por 4 variables. Conclusiones: La homofobia fue menos frecuente entre las mujeres, los que estudiaban en la capital, los que profesan el catolicismo y los que conocen/han atendido a un homosexual; por el contrario, los machistas fueron más homofóbicos.

ABSTRACT Background: The consequences of homophobia can affect the integrity, mental and physical health of homosexual individuals in society. There are few studies in Peru that have evaluated homophobia in the medical student population. Objective: To establish the social, educational and cultural factors associated with homophobia among Peruvian medical students. Methods: A cross-sectional analytical study was conducted in 12 medicine schools in Peru. Homophobia was defined according to a validated test, which was associated with other variables. Statistical associations were identified. Results: The lowest percentages of homophobic students (15-20%) were found in the four universities in Lima, while universities in the interior of the country had the highest percentages (22-62%). Performing a multivariate analysis, we found that the frequency of homophobia was lower for the following variables: the female gender (PRa=0.74; 95% CI, 0.61-0.92; p=0.005), studying at a university in Lima (PRa=0.57; 95% CI, 0.43-0.75; p<0.001), professing the Catholic religion (PRa=0.53; 95% CI, 0.37-0.76;p<0.001), knowing a homosexual (PRa=0.73; 95% CI, 0.60-0.90; p=0.003) and having treated a homosexual patient (PRa=0.76; 95% CI, 0.59-0.98; p=0.036). In contrast, the frequency of homophobia increased in male chauvinists (PRa=1.37; 95% CI, 1.09-1.72; p=0.007), adjusted by four variables. Conclusions: Homophobia was less common in women, in those who study in the capital, those who profess Catholicism and those who know/have treated a homosexual. In contrast, male chauvinists were more homophobic.

Introduction. This article summarizes the clinical practice guide (CPG) for the surgical treatment of patients with urolithiasis in the Social Security of Peru (EsSalud). Objective. To provide clinical recommendations based on evidence for the surgical treatment of patients with urolithiasis in EsSalud. Method. A guideline group (GEG) constituted by urologists and methodologists was formed, who formulated the clinical questions that were answered within the present CPG. For each of these questions systematic searches of systematic reviews and primary studies (when considered pertinent) were carried out in PubMed during 2018. The evidence was selected to answer each one of the clinical questions posed, later the certainty was evaluated of the evidence using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology. Regular work meetings were scheduled, in which the GEG reviewed the evidence and made recommendations, points of good clinical practice, and flow charts; using the GRADE methodology. The CPG was approved with Resolution No. 66-IETSI-ESSALUD-2018. Results. Six clinical questions on the subject of surgical treatment in urolithiasis were addressed. Based on these questions, 5 recommendations were formulated (2 strong recommendations and 3 conditional recommendations), 21 points of good clinical practice, and 3 management flow charts. Conclusion. This article summarizes the methodology and conclusions based on evidence from the CPG for the surgical treatment of patients with urolithiasis in EsSalud.
