RESUMO

Introducción. La cirugía estética tiene un importante reconocimiento en la sociedad contemporánea. Colombia se ubica como uno de los países en el que anualmente se practica un alto número de procedimientos estéticos invasivos; sin embargo, también se ha establecido que esta especialidad presenta frecuentes complicaciones cuyos riesgos necesitan ser registrados y sistematizados. Objetivo: Proponer un modelo adicional de sistematización de riesgos en cirugía estética que fortalezca los comúnmente empleados en Colombia. Metodología: El método utilizado fue el de estrategias de prevención de riesgos aplicadas al ámbito médico, empleando para este trabajo las dos primeras etapas, es decir, la sistematización de fuentes de información a partir de datos obtenidos de la gaceta jurisprudencial publicada por el Tribunal Nacional de Ética Médica y la identificación de la taxonomía de los eventos y errores médicos en cirugía estética. Resultados: En total se analizaron 57 providencias de las gacetas del Tribunal Nacional de Ética Médica sobre cirugía plástica y estética (privilegiando los procedimientos estéticos invasivos), pertenecientes a 2012, 2015 y 2017; de estas 34 cumplieron los criterios de selección; posteriormente, se realizó la sistematización de los riesgos hallados. Conclusiones: El modelo de tecnovigilancia empleado en Colombia resulta insuficiente a la hora de registrar los eventos y errores que se producen en procedimientos estéticos invasivos, por lo que es necesario emplear métodos adicionales que permitan garantizar una mayor seguridad en el paciente, prevenir daños lesivos y disminuir los procesos judiciales en contra del personal sanitario.

Introduction: Plastic surgery has an important place in today's contemporary society. Colombia ranks as one of the countries with the highest annual number of performed invasive esthetic procedures. However, it has been established that this type of special procedures showcases frequent complications and the need to register and systematize risks. Objective: To propose an additional model of risk systematization in cosmetic surgery that strengthens those commonly used in Colombia. Methodology: The method used was that of risk prevention strategies applied to the medical field, using for this work the first two stages, that is, the systematization of sources of information from data obtained from the jurisprudential gazette published by the National Court of Medical Ethics, and the identification of the taxonomy of events and medical errors in esthetic surgery. Results: In total, 57 orders of the National Court of Medical Ethics on plastic and esthetic surgery (favoring invasive esthetic procedures), from 2012, 2015, and 2017, were analyzed, of which 34 met the selection criteria; later, the found risks were systematized. Conclusions: The techno-vigilance model used in Colombia is insufficient to record events and errors that occur in invasive esthetic procedures, so it is necessary to use additional methods to ensure greater patient safety, prevent harm, and reduce judicial proceedings against healthcare personnel.

RESUMO

BACKGROUND: It is important to identify patients at increased risk of worsening of left ventricular ejection fraction (LVEF) after a myocardial infarction (MI). We aimed to identify the association of various potential biomarkers with LVEF impairment after an MI in South American patients. METHODS: We studied adult patients admitted to a University Hospital and diagnosed with an acute MI. Plasma concentrations of high-sensitivity C-reactive protein (hsCRP), proprotein convertase subtilisin/kexin type 9 (PCSK9), N-terminal prohormone of brain natriuretic peptide (NT-proBNP) and heart-type fatty-acid-binding protein (FABP3) were determined in samples drawn shortly after the event. Participants had a follow-up visit at least 45 days after the event. The primary endpoint was defined as any decline in LVEF at follow-up relative to baseline. RESULTS: The study included 106 patients (77.4% men, 22.6% women), mean age was 64.1, mean baseline LVEF was 56.6, 19% had a prior MI. We obtained a follow-up evaluation in 100 (94.4%) of participants, mean follow-up time was 163 days. There was a significant correlation between baseline PCSK9 and hsCRP (r = 0.39, p < 0.001). Baseline hsCRP concentrations were higher in patients who developed the endpoint than in those who did not (32.1 versus 21.2 mg/L, p = 0.066). After multivariate adjustment, baseline PCSK9, male sex and age were significantly associated with impairment in LVEF. The absolute change in LVEF was inversely correlated with baseline hsCRP (standardized coefficient = - 0.246, p = 0.004). CONCLUSION: High plasma levels of PCSK9 and hsCRP were associated with early decreases in LVEF after an MI in Latin American patients.

RESUMO

Handgrip strength (HGS) is a well-established indicator of muscle strength and a reasonable clinical predictor of metabolic health and diseases. This study explores the association between relative muscular strength and abdominal obesity (AO) in healthy Chilean adults. A convenience sample was recruited (n = 976) between 2018 and 2020. The HGS was determined by dynamometry. The anthropometry (weight, height, waist, and mid-arm circumference) and physical activity were also measured. The relative HGS (RHGS) was calculated by dividing the maximum HGS of the dominant hand by the body mass index. The AO was defined as a waist circumference (WC) >88 cm for women, and >102 cm for men. From the sample, 52.6% were women, 56.4% had excessive weight, and 42.7% had AO. The absolute and RHGS were greater in men compared to women (p < 0.001) and were decreased with age in both sexes. We observed a moderate negative correlation between WC and RHGS (rho = -0.54, and rho = -0.53, for men and women, respectively). The RHGS was lower in individuals with AO, independent of age and sex (p < 0.05). For each cm increase in WC, the odds of low RHGS (<25th percentile) increased by 12 and 9% for men and women, respectively. The AO is related to higher odds for low RHGS (OR: 1.72; 95% CI: 1.23-2.41). In our sample of healthy adults, a higher AO was associated with a lower muscle strength measured by dynamometry.

RESUMO

BACKGROUND: Bariatric surgery (BS) is the most effective procedure in the management of obesity, achieving a significant decrease in energy intake. AIM: To measure calorie and macronutrient intake in patients subjected to gastric bypass (GBP) or sleeve gastrectomy (SG). MATERIAL AND METHODS: We studied 53 patients subjected to SG and 27 subjected to GBP, who were in the first, second or sixth postoperative month. A food frequency consumption survey was applied by specialized nutritionists and their nutritional status was assessed. RESULTS: Mean calorie intake in months 1, 2 and 6 were 505, 600 and 829.8 kcal, respectively. A significantly higher intake was observed at month 1 in patients with those subjected to SG, compared with GBP patients. Protein consumption was <60 g/d, except at 6 months in patients with GBP. At months 1, 2 and 6, mean consumption of lipids were 17, 28 and 30 g/day, respectively. The figures for carbohydrates were 42, 31 and 77 g/day, respectively. At month 1, patients with GBP had a higher BMI, equalizing at 6 months with those of SG. At 6 months 37% of patients had a normal body mass index and 17% remained obese. A negative correlation was observed between weight loss and energy intake during the first month (rho: -0.40; p = 0.033). CONCLUSIONS: Patients subjected to BS had a low calorie and macronutrient intake in the first six postoperative months. Their calorie intake is negatively associated with weight loss, mainly during the first postoperative month.

RESUMO

BACKGROUND: Weight regain (WR) after bariatric surgery is common. Several factors involved in WR have been identified, but there has been little research on specific eating habits such as eating snacks rather than regular meals and being a "sweet-eater". AIM: To determine whether nutritional status, energy and macronutrient intake, eating behaviors and habits were associated with WR in the postoperative period. MATERIAL AND METHODS: We conducted a case-control study of patients who had undergone bariatric surgery. Cases were defined as those patients who gained ≥ 15% of weight in the first two years after surgery and controls as those who gained < 15% of weight. Participants completed a 24-hour dietary recall by phone; weight history was obtained from the medical chart. Logistic regression was used to identify nutritional and behavioral factors significantly related to WR. RESULTS: Fifty-four cases (77% female, 57% had undergone sleeve gastrectomy) and 50 controls (70% female, 58% had undergone Roux-en-Y gastric bypass surgery) participated. Their mean age was 43 and 40 years, respectively. We observed four eating and lifestyle habits independently associated with greater odds of post-surgery WR, namely being a "sweet-eater", a "grazer", sedentarism and consuming more daily calories. CONCLUSIONS: Eating more daily calories, being a "sweet-eater", a "grazer", and sedentarism were factors related with a greater risk of regaining weight after surgery.

ANTECEDENTES: La ganancia de peso después de la cirugía bariátrica es común. Se han identificado varios factores involucrados en la recuperación de peso, pero existe poca evidencia sobre hábitos alimentarios específicos tales como el patrón picoteador o ser un comedor de dulces. OBJETIVO: Determinar si el estado nutricional, ingesta calórica y de macronutrientes, patrones de ingesta alimentaria, y conducta alimentaria estuvieron asociados con la recuperación de peso en el período postoperatorio en pacientes de cirugía bariátrica. MATERIAL Y MÉTODO: Estudio de casos y controles de pacientes sometidos a cirugía bariatrica. Los casos fueron definidos como aquellos pacientes que aumentaron ≥ 15% de peso en los dos años siguientes a la cirugía, y los controles fueron aquellos que no tuvieron ganancia de peso. Los participantes respondieron telefónicamente un recordatorio de ingesta. El historial de peso se obtuvo de la ficha clínica. Se utilizó una regresión logística para identificar factores nutricionales y de comportamiento relacionados significativamente con la recuperación de peso. RESULTADOS: Participaron 54 casos (77% mujeres; 58% sometidos a manga gástrica) y 50 controles (70 % mujeres; 58% sometidos a baipás gástrico). La edad promedio de ellos fue 43 y 40 años, respectivamente. Se observó cuatro hábitos alimentarios y de estilo de vida asociados independientemente con mayores probabilidades de ganancia de peso postcirugía: comedor de dulces, picoteador, sedentarismo y mayor ingesta calórica diaria. Conclusiones: Una mayor ingesta energética diaria, el consumo de dulces, los picoteos y el sedentarismo se relacionan con una mayor probabilidad de ganancia de peso en el postoperatorio de cirugía bariátrica.

RESUMO

Resumen La limitación del esfuerzo terapéutico (LET) es toda acción que implique suspender o no iniciar tratamientos o medidas terapéuticas en pacientes que no se beneficiarán clínicamente. En Latinoamérica, las investigaciones realizadas dejan en evidencia la falta de familiarización y discordancia que hay alrededor del tema y sus prácticas. El presente estudio buscó objetivizar el conocimiento en LET del personal de salud de una institución de Medellín, a partir de una encuesta autoaplicada que permitió el desarrollo de un estudio descriptivo de tipo transversal, con muestreo no probabilístico. Dentro de los resultados se encontró que el 56,5 % de los encuestados refirió conocer el concepto, y el 90 % manifestó aplicarlo. Sin embargo, había discordancias dentro de los conceptos clave de la definición y el ejercicio.

Abstract Limitation of therapeutic effort (LTE) is any action that involves suspending or not initiating medical treatment or therapeutic measures in patients who will not receive any clinical benefit. In Latin America, some research has proven a lack of familiarization and disagreement with the subject and its practices. The present study tried to objectify the knowledge of LTE of healthcare personnel at an institute in Medellín using a self-administered survey that allowed conducting a cross-sectional descriptive study with non-probabilistic sampling. Within the results, 56.5 % of respondents understood the concept of LTE, and 90 % applied it actively. However, there were discrepancies regarding the core concepts of the definition and practice.

RESUMO

BACKGROUND: Febuxostat is approved in the United States for the management of hyperuricemia in patients with gout. In November 2017 the FDA released a warning alert on a possible link between febuxostat and cardiovascular disease (CVD) reported in a single clinical trial. OBJECTIVE: To conduct a systematic review and meta-analysis and assess the risk of major adverse cardiovascular events (MACE) in patients receiving febuxostat compared to a control group. METHODS: We searched the MEDLINE and EMBASE database for studies published up until March 2018. We included randomized clinical trials (RCTs) that compared febuxostat to control groups including placebo and allopurinol. We calculated the pooled relative risk (RR) of MACE and cardiovascular disease (CVD) mortality with the corresponding 95% confidence intervals (CI). RESULTS: Our search yielded 374 potentially relevant studies. Among the 25 RCTs included in the systematic review, 10 qualified for the meta-analysis. Among the 14,402 subjects included, the median age was 54 years (IQR 52-67) and 90% were male (IQR 82-96); 8602 received febuxostat, 5118 allopurinol, and 643 placebo. The pooled RR of MACE for febuxostat was 0.9; 95% CI 0.6-1.5 (p= 0.96) compared to the control. The RR of CV-related death for febuxostat was 1.29; 95% CI 1.01-1.66 (p=0.03). CONCLUSIONS: Compared with other SU-lowering treatments, febuxostat does not increase or decrease the risk of cardiovascular disease but may increase the risk of CVD death. More RCTs measuring cardiovascular safety as a primary outcome are needed to adequately evaluate the risk of CVD with febuxostat.

RESUMO

RESUMEN La cirugía bariátrica (CB) ha demostrado ser una alternativa segura y eficaz para la resolución de la obesidad y sus comorbilidades. Parte del éxito de la CB, radica en el manejo nutricional del paciente, para lo que se requiere de un equipo médico-nutricional, entrenado en nutrición bariátrica, con el objetivo de evitar déficit nutricional y modificar hábitos a largo plazo. En la actualidad, no existe en Chile un consenso sobre el protocolo de manejo nutricional pre y post CB. El objetivo del 1er Consenso Chileno de Nutricionistas en Cirugía Bariátrica, es ser una guía para los nutricionistas que asisten a pacientes bariátricos. Este documento resume el trabajo realizado por los Nutricionistas de Sociedad Chilena de Cirugía Bariátrica y Metabólica (SCCBM), quienes durante 5 años trabajaron en reuniones presenciales y comisiones de estudio, revisando evidencias científicas, guías de tratamiento y recomendaciones de expertos, que fundamentarán las recomendaciones alimentario nutricional para cada tema. El resultado es un documento que homologa criterios para el manejo nutricional de pacientes bariátricos y genera los tópicos mínimos para asegurar la atención nutricional de calidad en los equipos bariátricos chilenos.

ABSTRACT Bariatric surgery (BS) has proven to be a safe and effective alternative for the resolution of obesity and its comorbidities. Part of the success of BS lies in the nutritional management of the patient, for which a medical-nutritional team, trained in bariatric nutrition, is required with the aim of modifying long-term habits and avoiding nutritional deficit. At present, there is no consensus in Chile on the pre-and post-BS nutritional management protocol. The objective of the 1st Consensus of Chilean Nutritionists on Bariatric Surgery is to be a guide for nutritionists who assist bariatric patients. This document summarizes the work done by Nutritionists of the Chilean Society of Bariatric and Metabolic Surgery (SCCBM), who, during 5 years, worked in face-to-face meetings and study commissions, reviewing scientific evidence, treatment guides and expert recommendations, which will support nutritional nutrition recommendations for each topic. The result is a document that standardizes criteria for the nutritional management of bariatric patients and generates the minimum topics to ensure quality nutritional care for Chilean bariatric teams.
