Confirmed cases of COVID-19 after vaccination against COVID in health personnel in Bogotá, Colombia.

OBJECTIVE: The present study aims to estimate the frequency of COVID 19 infections in vaccinated health personnel at a Los CObos Medical Center in Bogotá, Colombia. The percentage of people positive to the PCR test and their clinical characteristics were analyzed. METHODS: We performed a cross-sectional study. The primary study variable was the COVID vaccination registry. We analyzed sex, age, signs, and symptoms. Multivariable logistic regression was applied to assess changes over time and to identify variables associated with vaccination in target groups. RESULTS: A cohort of 999 people working at Los Cobos Medical Center and followed from March to August 2021. The average age of this cohort was 37.0 years (devest = 10.5 years), 67.7 % were women. Two hundred eleven physicians, 287 nurses, 305 assistants, and 196 clerks follows. In addition, 8.4 % to be PCR positive after vaccination. The average age was 36.0 (devest = 23.4 years), 59 women and 25 men. Of these, 15 were administrative, 14 were doctors, 29 nurses, and 26 nursing assistants. The vaccination status found that 21.4 % do not vaccinates, 7.1 % were partially vaccinated, and 71.4 % with a complete schedule. When questioned about symptoms in these patients, 4.0 % were symptomatic, and 5.9 % were asymptomatic. CONCLUSIONS: A recent epidemiological study involving 12,364 health workers with a mean age of 38 years quantifies the protection in six months from the vaccine. The presence of antibodies was associated with 83 % protection against active SARS-CoV-2 infection (PCR positivity during the study period), which confirms the existence of protective Immunity at levels comparable to those obtained by the approved vaccines; our study found effectiveness of 92.6 %. Higher than that found in this study, possibly explained by the characteristics of the individuals included.

Cuando se justifica la colostomía en trauma de colón? / When is colostomy justified in colon trauma

Se trata de un estudio descriptivo prospectivo, en el cual se incluyen los pacientes que ingresaron a el Hospital Simón Bolivar con heridas del Colón intraperitoneal, quienes adicionalmente no presentaron shock intraoperatorio y no tuviesen más de 12 horas de evolución desde el trauma inicial; a estos pacientes se les realizó reparo primario de la lesión del colon sin procedimientos derivativos adicionales tipo colostomía. Durante un período comprendido desde Junio 1993; un total de 75 pacientes cumplían con los requisitos, encontramos una morbilidad cercana a el 20por ciento, sin que ésta se pueda atribuir a el reparo primario y si se encuentra en una estrecha relación con la severidad del trauma inicial. Se analizaron otras variables: sexo, puntaje P.A.T.I., clasificación de Flint, transfusiones sanguíneas, shock, severidad de peritonitis, localización de la herida. Todos los pacientes fueron seguidos hasta 30 días después de ser dados de alta del hospital.
