This study aimed at studying the clinical and anatomopathological characteristics, treatment and survival of patients with differentiated thyroid cancer. A retrospective cohort study was conducted with data from 150 patients from a Peruvian hospital between the years 2010 to 2020. Characteristics and survival (Kaplan-Meier method) were described. The mean age was 48.3 years, 130 participants (86.7%) were women and the most frequent histologic type was papillary 94.6%. Of the participants, 74.2% had TNM stage I, 70.7% had total thyroidectomy and 68.7% received radioactive iodine. Overall survival at 5 years was 89.3%, being lower in those with TNM stage IV and higher in those who used radioactive iodine. In conclusion, in a hospital in Cusco, differentiated thyroid cancer was more frequent in women and survival was lower compared to reports from other countries.

Antecedentes El embarazo ectópico cervical es la implantación del embrión en la zona de revestimiento del canal endocervical. Representa menos del 1% de todos los embarazos ectópicos. Reporte de Caso Reportamos dos pacientes que acuden a consulta de emergencia por sangrado transvaginal. El diagnóstico de embarazo ectópico cervical fue realizado por ecografía transvaginal (7 y 8 semanas de gestación). Se inició tratamiento con metotrexato (paciente de 28 años) y metotrexato-ácido folínico (paciente de 35 años). Debido al aumento de la hormona gonadotropina coriónica humana se decidió realizar una histerectomía abdominal (paciente de 28 años) y curetaje-cerclaje cervical tipo McDonald (paciente de 35 años). No hubo complicaciones posteriores a la cirugía en ambas pacientes. Conclusiones El tratamiento del embarazo ectópico cervical es controversial. Se debe elegir la terapia más apropiada para preservar la fertilidad y evitar complicaciones como la hemorragia.

Introducción La incidencia de cáncer de tiroides se ha incrementado en el mundo. En Perú existen limitados informes que describan la epidemiología nacional y regional de esta neoplasia. Objetivo Describir la tendencia de la prevalencia y mortalidad de cáncer de tiroides registrada en el Ministerio de Salud de Perú. Métodos Se realizó un estudio descriptivo de tendencias con datos secundarios, obtenidos de una fuente de información pública de Perú. Se evaluó el registro de codificación CIE 10: C73.0, por grupo de edad, año y región. Se calcularon las tasas estandarizadas de la prevalencia (periodo 2005 a 2016) y mortalidad (periodo 2005 a 2015) por regiones y año de estudio. Resultados Durante el periodo 2005-2016 se registraron 19 513 casos de cáncer de tiroides. El grupo etario con mayor frecuencia fue de 30 a 59 años (57,7%). La prevalencia incrementó de 4,7 a 15,2 casos por 100 000 habitantes en el periodo 2005-2016 y la región de la costa fue la que presentó mayor ascenso. Asimismo, se registraron 1596 muertes por cáncer de tiroides (periodo 2005 a 2015) con mayor frecuencia en mayores de 60 años (75,5%). La tasa estandarizada de mortalidad por 100 000 habitantes aumentó de 0,67 en 2005 a 0,72 en 2015, siendo la región de la sierra la de mayor incremento. Conclusiones La prevalencia por cáncer de tiroides aumentó y la mortalidad se mantuvo constante en el periodo estudiado. Estos resultados animan a explorar factores sociales y de la población que hayan podido influir en ello; además de mejorar los registros poblacionales de esta y otras neoplasias en Perú.

Abstract Introduction: Diabetic foot is one of the main complications of diabetes mellitus; however, in hospitals of provinces from Perú, the relationship of this condition with hospital stay has not been calculated. Objective: To determine the association between hospitalization time and diabetic foot in three hospitals from Cusco, Perú. Methods: A cross-sectional study of secondary data analysis was conducted. We analyzed the data of patients with type 2 diabetes mellitus admitted to the internal medicine service between January and December 2016, in three tertiary hospitals in Cusco, Peru. Correlation coefficients and p-values were calculated using generalized linear models, with Gaussian family and identity function, adjusted by intervening variables. Values of p < 0.05 were considered statistically significant. Results: Of the 153 patients, 14% (21) had a diabetic foot diagnosis, and their median age was 61 years (interquartile range 56 to 68). Those who had a diabetic foot had on average 20 hospitalization days. A strong association was found between a diabetic foot and the number of hospitalization days (17 days more, p = 0.003); adjusted by six variables. Those patients with a history of hypertension had more hospitalization days (10 days more, p = 0.011) and those admitted to a hospital of the Ministry of Health, had fewer hospitalization days (10 days less, p = 0.032). Conclusion: The group of patients with diabetic foot had a longer hospitalization time. The longer hospitalization time could be due to complications of the disease or difficulties in management.

Objective: To characterise and determine factors associated with the first authorship and author for correspondence of women who published in Peruvian journals indexed in SciELO between 2010 and 2015. Methodology: Cross-sectional bibliometric analysis of secondary data. All the scientific publications had at least one female author, were evaluated in the 9 Peruvian journals indexed to the SciELO database between 2010 and 2015. The characteristics of the article, authorship and filiation were evaluated. Descriptive and analytical statistics were obtained. Results: Of the 795 scientific publications that had at least one female author, 41% (324) and 35% (253) had a woman as the first author or corresponding author, respectively. The journal that had publications with the largest female participation was the National Institute of Health (153). As regards the year of publication, the percentages of women as the first (R2 = 0) or corresponding author (R2 < .01) did not vary. When performing the bivariate analysis, there was a lower frequency of first authors reporting cases (PR: 0.46, 95% CI: 0.27-0.78), and short originals (PR: 0.46, 95% CI: 0.24-0.90). First authors were more frequent (RP: 1.60, 95% CI: 1.11-2.30) in the hereditary medical journal, and the stomatology journal had a higher frequency of female first authors (RP: 2.09; 95% CI: 1.31-3.35) and corresponding authors (RP: 2.15; 95% CI: 1.30-3.56). Conclusion: The data and leadership of women in Peruvian scientific publications is still a minority and is stagnant in time. For this reason, collaboration and training networks must be created that are more inclusive with women, in order to support and help sustain its growth.

INTRODUCTION Diabetes mortality has increased in recent years. In Peru, there are few studies on in-hospital mortality due to type 2 diabetes in the provinces. OBJECTIVE To determine factors associated to hospital mortality in patients with diabetes mellitus type 2 in three hospitals from Cusco-Peru. METHODS An analytical cross-sectional study was performed. All patients with diabetes mellitus type 2 hospitalized in the city of Cusco during the 2016 were included. Socio-educational and clinical characteristics were evaluated, with "death" as the variable of interest. The crude (cPR) and adjusted (aPR) prevalence ratios were estimated using generalized linear models with Poisson family and log link function, with their respective 95% confidence intervals (95% CI). The values p <0.05 were considered significant. RESULTS A total of 153 patients were studied; 33.3% (51) died in the hospital. The mortality rate increased when the following factors were associated: age of the patients increased the mortality rate by one-year increments (aPR: 1.02; CI95%: 1.01-1.03; p<0.001); to have been admitted by the emergency service (aPR: 1.93; CI95%: 1.34-2.77; p<0.001); being a patient who is readmitted to the hospital (aPR: 2.01; CI95%: 1.36-2.98; p<0.001); and patients who have had a metabolic in-hospital complication (aPR: 1.61; CI95%: 1.07-2.43; p=0.024) or renal in-hospital complications (aPR: 1.47; CI95%: 1.30-1.67; p<0.001). Conversely, the mortality rate was reduced when admission was due to a urinary tract infection (aPR: 0.50; CI95%: 0.35-0.72; p<0.001); adjusted by seven variables. CONCLUSIONS A third of hospitalized diabetes mellitus type 2 patients died during the study period. Mortality was increased as age rises, patients admitted through emergency rooms, patients who were readmitted to the hospital, and patients who had metabolic or renal complications. Patients admitted for a urinary tract infection had a lower mortality rate.

Background: Empathy is considered the central axis in the doctor-patient relationship, an important aspect in medical practice that influences a better performance of the doctor and medical students. It has been reported that medical students experience a pronounced decline in empathy as they proceed in the profession. Objective: To evaluate empathy in medical students of a public university in the south sierra of Peru. Method: Observational, descriptive, cross-sectional study was conducted on 206 students by stratified random sampling. The Jefferson Scale of Medical Empathy in its version "S, was used as a measurement tool. Results: Of the total of 206 students that participated, 53.4% were males, with a mean age of 21.09 years. The overall empathy mean was 87.77, with only 31% of the students obtaining an adequate level of empathy. Slightly higher mean scores were obtained in the men, and the highest scores were obtained in the first and third year, with no significant differences being found. Conclusions: It was found that males, students of first and third year, and those who recently started permanent contact with the patient had a higher mean score.
