- PublicaciónSólo datosAlcohol consumption and suicide risk in medical internship: A Peruvian multicentric study(Blackwell Publishing, 2019-02-20) Toro Huamanchumo, Carlos J.; Carrasco‐Farfan, Carlos A.; Alvarez‐Cutipa, Daniela; Vilchez‐Cornejo, Jennifer; Lizana‐Medrano, Magaly; Durand‐Anahua, Paula A.; Rengifo‐Sanchez, Jorge A.; Rebatta‐Acuña, Alexis; Cubas, Wildor S.; Arroyo‐Hernandez, HugoIntroduction and Aim: Suicide and harmful alcohol consumption are major health problems, especially in medical students. This study aimed to evaluate the association between risk for alcohol abuse and suicide risk in medical interns of Peruvian hospitals. Design and Methods: We conducted a multicentre cross-sectional study in medical interns from 18 Peruvian hospitals. We measured suicide risk, risk for alcohol abuse, depression and self-esteem using the Plutchik Suicide Risk Scale, CAGE, Zung Self-Rating Depression Scale and Rosenberg Self-Esteem Scale, respectively. We used χ2 and Student t-tests for descriptive analysis. To evaluate the association between risk for alcohol abuse and suicide risk we generated crude and adjusted Poisson regression models with robust variance and estimated prevalence ratios with 95% confidence intervals. Results: We surveyed 433 medical interns. The prevalence of suicide risk and risk for alcohol abuse was 19.6% and 27.5%, respectively. We found significant differences in suicide risk according to age (P < 0.001), region of origin (P = 0.002), with whom the participant lived (P < 0.001), university of origin (P = 0.040), type of hospital (P = 0.042), family history of attempted suicide (P = 0.043), self-esteem level (P < 0.001) and alcohol consumption (P < 0.001). In the adjusted model, age (PRa: 1.11, 95% confidence interval 1.05–1.17) and risk for alcohol abuse (PRa: 7.60, 95% confidence interval 4.46–12, 96) were associated with suicide risk. Discussion and Conclusions: Two out of 10 medical interns had a positive screening for suicide risk. Age and especially risk for alcohol abuse were the associated variables. © 2019 Australasian Professional Society on Alcohol and other Drugs
- PublicaciónSólo datosAssociation between waist circumference and waist-to-height ratio with insulin resistance biomarkers in normal-weight adults working in a private educational institution(Elsevier Ltd, 2019-05) Urrunaga Pastor, Diego; De La Fuente-Carmelino, Luciana; Toro Huamanchumo, Carlos J.; Pérez-Zavala, Miriam; Benites Zapata, Vicente A.Aim: To assess the association between elevated waist circumference (WC)and high waist-to-height ratio (WHtR)with insulin resistance biomarkers. Methods: We conducted an analytical cross-sectional study in normal-weight adults. Participants were divided in two groups according to WC or WHtR levels. We considered values of WC ≥ 90 in male participants and WC ≥ 80 in adult women as elevated, and values of WHtR≥0.50 as high, for both genders. Our outcomes were high triglycerides to HDL-cholesterol (TG/HDL-C)ratio and elevated triglycerides and glucose index (TGI). We considered values of TG/HDL-C ratio ≥ 3 as high and TGI values ≥ 8.37 as elevated. We elaborated crude and adjusted Poisson generalized linear models to evaluate the proposed associations and explored the gender interaction using stratified models. We reported the prevalence ratio (PR)with their respective 95% confidence intervals (95%CI). Results: We analyzed 355 participants. The prevalence of elevated WC and high WHtR was 17.2% (n = 61)and 33.2% (n = 118), respectively, while the prevalence of high TG/HDL-C ratio and elevated TGI was 24.8% (n = 88)and 12.7% (n = 45), respectively. In the adjusted regression model, elevated WC was associated with high TG/HDL-C ratio only in female participants (aPR = 3.61; 95%CI: 1.59–8.20). Similarly, high WHtR was associated with high TG/HDL-C ratio in women (aPR = 2.54; 95%CI:1.08–5.97). We found an association with statistically marginal significance between elevated WC and elevated TGI in women (aPR = 1.54; 95%CI: 0.95–2.50); as well as for the association between high WHtR and elevated TGI in male participants (aPR = 1.87; 95%CI: 1.00–3.50).
- PublicaciónSólo datosDepression and Abuse During Medical Internshipsin Peruvian Hospitals(Elsevier, 2018-10) Vilchez Cornejo, Jennifer; Viera-Morón, Ronald David; Larico-Callac, Gabriel; Alvarez-Cutipa, Daniela Carla; Sánchez-Vicente, Juan C.; Taminche-Canayoe, Ruth; Carrasco-Farfan, Carlos Andres; Palacios-Zegarra, Alexis Armando; Mendoza-Flores, Cynthia; Quispe-López, Pedro; Toro Huamanchumo, Carlos J.Objective: To estimate the prevalence of depression and abuse and identify the associatedfactors in medical interns in Peruvian hospitals.Methods: We conducted a multicentre, cross-sectional and analytical study during themonths of March to May 2016. We included medical interns from 18 Peruvian hospitals,in Lima and provinces. We used a survey that included sociodemographic data and a scaleto measure the perception of abuse (psychological, physical and sexual). In addition, weused the Spanish version of the PHQ-9 to evaluate depression. We used Poisson regressionwith robust variances to calculate prevalence ratios (PRs).Results: A total of 402 medical interns participated in the study, the median age was 25[IQR: 21–33], and 52.7% were male. Moreover, 25.4% of them suffered from depression. In theadjusted model, the variables associated with depression were age (PRa = 1.15), the numberof hours they sleep per day (PRa = 1.23), being a woman (PRa = 3.33), performing the intern-ship in a province (PRa = 0.25), studying at a public university (PRa = 0.64), living with parents(PRa = 0.65) or alone (PRa = 0.33), and having perceived some type of abuse (PRa = 1.07).Conclusions: A quarter of surveyed medical interns had depression. Early screening is neces-sary to identify perceived abuse and other triggering depression factors that may adverselyaffect work performance and overall mental health during medical internships.
- PublicaciónSólo datosHigh triglycerides to HDL-cholesterol ratio is associated with insulin resistance in normal-weight healthy adults(Elsevier B.V., 2019-02) Pantoja-Torres, Betzi; Toro Huamanchumo, Carlos J.; Urrunaga Pastor, Diego; Guarnizo Poma, Mirella; Lázaro Alcántara, Herbert; Paico Palacios, Socorro; Del Carmen Ranilla Seguin, Vitalia; Benites Zapata, Vicente A.Aim: To evaluate the association between high triglyceride/HDL-cholesterol (TG/HDL-C) ratio and insulin resistance (IR) or hyperinsulinemia after oral glucose tolerance test (OGTT) in normal-weight healthy adults. Methods: We carried out an analytical cross-sectional study in euthyroid non-diabetic adults, who attended the outpatient service of a private clinic in Lima-Peru from 2012 to 2016. Participants were divided in two groups according to the presence or absence of high TG/HDL-C ratio, IR or hyperinsulinemia after OGTT. TG/HDL-C ratio values ≥ 3 were considered as high. IR was defined as a Homeostasis Model Assessment (HOMA-IR) value ≥ 2.28 and hyperinsulinemia after OGTT as a serum insulin value ≥ 80μU/mL after 120 min of 75-g glucose intake. We elaborated crude and adjusted Poisson generalized linear models to evaluate the association between high TG/HDL-C ratio and IR or hyperinsulinemia after OGTT and reported the prevalence ratio (PR) with their respective 95% confidence intervals (95%CI). Results: We analyzed the data of 118 individuals. Prevalence of high TG/HDL-C ratio was 17.8% (n = 21) while the prevalence of IR and hyperinsulinemia after OGTT was 24.6% (n = 29) and 17.0% (n = 20), respectively. TG/HDL-C-ratio values were positively correlated with HOMA-IR (r = 0.498; p < 0.01) and serum insulin after OGTT (r = 0.326; p < 0.001). In the adjusted model, high TG/HDL-C ratio was associated with both IR (aPR = 3.16; 95%CI: 1.80–5.77) and hyperinsulinemia after OGTT (aPR = 2.36; 95%CI: 1.20–4.63). Conclusions: High TG/HDL-C ratio was associated with both IR markers used in our study, appearing to be a clinically useful tool to assess IR in euthyroid normal-weight adults without type 2 diabetes mellitus. © 2018 Diabetes India

However, in Peru, a country with scarce scientific production, these works are not usually published in indexed scientific journals, which drastically limits their visibility and impact. Objective: To characterize the scientific production of undergraduate students of the Human Medicine School of University of San Martin de Porres, during the period 2005-2016. Methods: Bibliometric study. A bibliographic search was carried out in the web portals of the databases SCOPUS, SciELO, LILACS and LIPECS, using terms that identify the FMH-USMP. We selected the articles that had a student of the Human Medicine School of University of San Martin de Porres as author. Subsequently, the characteristics of interest for each article were collected. The statistical analysis was carried out with the statistical software Stata v13. Results: A total of 160 scientific publications with student participation were found. On average, 1.63 % of the students of the Human Medi cine School of University of San Martin de Porres participated in some scientific publication yearly. Among the articles evaluated, 39 (24.4 %) were published in journals indexed to Scopus, 31.3 % and 55.6 % had as their first author and correspondent author a student of the Human Medicine School of University of San Martin de Porres, respectively, while 66.9 % had the participation of students from one of the scientific societies of medical students (SOCEM) of the Human Medicine School of the University of San Martin de Porres.

- PublicaciónAcceso abiertoProducción científica y licenciamiento de escuelas de medicina en el Perú(Instituto Nacional de Salud, 2019-03) Mayta Tristán, Percy; Toro Huamanchumo, Carlos J.; Alhuay Quispe, Joel; Pacheco Mendoza, JosmelThe new university law 30220 of 2014 introduced the mandatory institutional licensing of all Peruvian universities by the National Superintendence of Higher University Education (SUNEDU, in Spanish). The first undergraduate program to go through this process will be medicine. The licensing of medical programs is necessary to ensure that the conditions in which the program is taught in Peru are adequate, with a high probability of closing some medical schools. Once a medical school has demonstrated that it meets the basic conditions of quality, a qualitative and quantitative evaluation is carried out that includes three criteria: scientific production in the Web of Science, impact measured through the H index, and results of the national medical exam, to determine the years of licensing. This article evaluates the quantitative indicators linked to research using Web of Science and Scopus, in addition to making technical and methodological revisions of them. Suggestions for the other indicators are also covered by this article.
- PublicaciónSólo datosTriglycerides and glucose index as an insulin resistance marker in a sample of healthy adults(Elsevier B.V., 2019-02) Toro Huamanchumo, Carlos J.; Urrunaga Pastor, Diego; Guarnizo Poma, Mirella; Lázaro Alcántara, Herbert; Paico Palacios, Socorro; Pantoja Torres, Betzi; Ranilla-Seguin, Vitalia Del Carmen; Benites Zapata, Vicente A.Aim: To assess the association between elevated triglycerides/glucose index (TGI) and insulin resistance (IR) or hyperinsulinemia after oral glucose tolerance test (OGTT) in a sample of healthy adults. Methods: We conducted an analytical cross-sectional study in euthyroid non-diabetic adults, who attended the outpatient service of a private clinic in Lima-Peru during the 2012–2016 period. Participants were categorized in two groups according to the presence or absence of elevated TGI, IR or hyperinsulinemia after OGTT. A TGI value ≥ 8.65 was considered as elevated. We defined IR as a Homeostasis Model Assessment (HOMA-IR) value ≥ 2.28 and hyperinsulinemia after OGTT as a serum insulin value ≥ 80μU/mL after 120 min of 75-g glucose intake. We elaborated crude and adjusted Poisson regression models to assess the association between elevated TGI and IR or hyperinsulinemia after OGTT. The reported association measure was the prevalence ratio (PR) with their respective 95% confidence intervals (95%CI). Results: We analyzed 118 individuals, the average age was 37.5 ± 11.3 years, 21 (17.8%) were males and the median BMI was 22.7 ± 1.6 kg/m2. The prevalence of elevated TGI was 25.4% (n=30) while the prevalence of IR and hyperinsulinemia after OGTT was 24.6% (n=29) and 17.0% (n=20) respectively. In the adjusted model, elevated TGI was associated with both IR (aPR=6.36; 95%CI: 3.41–11.86) and hyperinsulinemia after OGTT (aPR=4.19; 95%CI: 1.81–9.70). Conclusions: We found that elevated TGI was associated with both IR markers in a sample of euthyroid adults without T2DM and with a normal BMI. The simplicity of the TGI calculation makes it the first-choice alternative when the hyperinsulinemic-euglycemic clamp or HOMA-IR are not available. © 2018 Diabetes India
- PublicaciónSólo datosWorkplace violence by specialty among Peruvian medical residents(Public Library of Science, 2018-11-29) Nieto-Gutiérrez, Wendy; Toro Huamanchumo, Carlos J.; Taype Rondán, Álvaro; Timaná-Ruiz, Raúl; Alva Diaz, Carlos; Jumpa-Armas, David; Escobedo-Palza, SeimerObjective To determine the prevalence of workplace violence among Peruvian medical residents and to evaluate the association between medical specialty and workplace violence per type of aggressor. Methods This was a cross-sectional secondary analysis that used data from the Peruvian Medical Residents National Survey 2016 (ENMERE-2016). The outcome of interest was workplace violence, including physical and verbal violence, which were categorized according to the perpetrator of violence (patients/relatives and worker-to-worker). Primary exposure was the medical specialty, categorized as clinical, surgical, and other specialties. To evaluate the associations of interest, we estimated adjusted prevalence ratios (PR) with their respective 95% confidence intervals (95% CI) using Poisson regression models with robust variances. Results A total of 1054 Peruvian medical residents were evaluated. The mean age was 32.6 years and 42.3% were female. Overall 73.4% reported having suffered of workplace violence sometime during the residency, 34.4% reported violence from patients/relatives, and 61.1% reported worker-to-worker violence. Compared with clinical residents, surgical residents had a lower prevalence of violence from patients/relatives (PR: 0.71; 95% CI: 0.59–0.87), but a higher prevalence of worker-to-worker violence (PR: 1.11, 95% CI: 1.01–1.23).
