Establishment of a multisite umbrella cohort study protocol to describe the epidemiology and aetiologies of acute undifferentiated febrile illness in Latin America.

INTRODUCTION: Acute undifferentiated febrile illnesses (AUFIs) impose a large burden in the tropics. Understanding of AUFI's epidemiology is limited. Insufficient diagnostic capacity hinders the detection of outbreaks. The lack of interconnection in healthcare systems hinders timely response. We describe a protocol to study the epidemiology and aetiologies of AUFI and pathogen discovery in strategic areas of Latin America (LA). METHODS AND ANALYSIS: Global Infectious Diseases Network investigators comprising institutions in Colombia, Dominican Republic, México, Perú and the USA, developed a common cohort study protocol. The primary objective is to determine the aetiologies of AUFI at healthcare facilities in high-risk areas. Data collection and laboratory testing for viral, bacterial and parasitic agents are performed in rural and urban healthcare facilities and partner laboratories. Centralised laboratory and data management cores deploy diagnostic tests and data management tools. Subjects >6 years with fever for <8 days without localised infection are included in the cohort. They are evaluated during the acute and convalescent phases of illness. Study personnel collect clinical and epidemiological information. Blood, urine, nasal or pharyngeal swabs and saliva are collected in the acute phase and blood in convalescent phase. Specimens are banked at -80°C. Malaria, dengue and COVID-19 are tested onsite in the acute phase. The acute-phase serum is PCR tested for dengue, chikungunya, Venezuelan equine encephalitis, Mayaro, Oropouche, Zika, and yellow fever viruses. Paired convalescent and acute serum antibody titters are tested for arbovirus, Leptospira spp, and Rickettsia spp. Serum is used for viral cultures and next-generation sequencing for pathogen discovery. Analysis includes variable distributions, risk factors and regression models. Laboratory results are shared with health authorities and network members. ETHICS AND DISSEMINATION: The protocol was approved by local ethics committees and health authorities. The results will be published in peer-reviewed journals. All study results are shared with local and regional health authorities.

Decline in empathy levels and sex differences in medical students from the Caribbean / Declinación empática y diferencias según el sexo en estudiantes de medicina del Caribe

Abstract Introduction: Empathy is an important trait in the training of medical students, as it has been shown that it improves the doctor-patient relationship. Objective: To evaluate the decline of empathy levels and possible sex differences in undergraduate medical students from the Universidad Central del Este, Dominican Republic. Materials and methods: Exploratory cross-sectional study. A Spanish version of the Jefferson Scale of Empathy for Medical Students (S-version) Scale was administered in September 2018 to 1 144 1st-year to 5th-year medical students (887 women and 257 men). Data reliability was verified using the Cronbach's alpha and the intraclass correlation coefficient (ICC). A generalized linear equation model (Type III) was applied to analyze data and the Wald chi-squared test was used to determine differences in overall empathy levels and the mean scores obtained in each of its three components based on the year of medical training and sex. Results: Cronbach's alpha was satisfactory (0.839), and the ICC was 0.834 (F=5.68; p=0.005). The variability of the estimated curves in relation to empathic behavior by course (year of medical training) and sex was observed using linear and non-linear regression equations: Wald x2=115.6, p=0.0001 between courses; and Wald x2 =12.85, p=0.001 between men and women. Conclusions: Sex differences were observed regarding empathy levels in the study population. Moreover, a decline in empathy levels (overall empathy and Compassionate Care component in men and Walking in the Patient's Shoes component in men and women) was also observed as students progressed in their medical training. The behavior of these data raises questions regarding the need to determine the factors causing these differences and the decline in empathy levels.

Resumen Introducción. La empatia es un rasgo importante en los estudiantes de medicina, ya que se ha demostrado que mejora la relación médico-paciente. Objetivo. Evaluar la declinación empática y las posibles diferencias según el sexo en los niveles de empatia en estudiantes de pregrado de Medicina en la Universidad Central del Este, República Dominicana. Materiales y métodos. Estudio exploratorio transversal. La versión en español de la Escala de Empatia de Jefferson adaptada para estudiantes de medicina (versión S) fue aplicada a 1 144 estudiantes de medicina de 1° a 5° año (887 mujeres y 257 hombres). La confiabilidad de los datos se verificó mediante el alfa de Cronbach y el coeficiente de correlación intraclase (CCI). Los datos se analizaron utilizando un modelo de ecuación lineal generalizada (Tipo III) y se utilizó la prueba x2 de Wald para determinar las diferencias en los niveles globales de empatia y los puntajes promedio de sus tres componentes según el año de formación y el sexo. Resultados. El alfa de Cronbach fue satisfactorio (0.839) y el CCI fue de 0.834 (F=5.68; p=0.005). Mediante ecuaciones de regresión lineal y no lineal se observó variabilidad de las curvas estimadas en relación con el comportamiento empático según el curso (año de formación médica) y el sexo: entre cursos: x2 de Wald= 115.6; p=0.000i, y entre hombres y mujeres: x2 de Wald= 12.85; p=0.001). Conclusiones. Se observaron diferencias en los niveles de empatia según el sexo; también se evidenció una declinación en los niveles de empatia (empatia global y componente Cuidado con compasión en los hombres, y en el componente Ponerse en los zapatos del otro en hombres y mujeres) a medida que los estudiantes avanzaban en su formación. El comportamiento de estos datos genera interrogantes relacionados con la necesidad de determinar los factores que causan estas diferencias y dicha declinación empática.
