The effect of bariatric surgery on metabolic syndrome: A retrospective cohort study in Colombia.

Introduction and Objective: Metabolic syndrome (MetS) represents a group of metabolic abnormalities. It is currently a pandemic, and its prevalence is on the rise. MetS has a direct relationship with obesity, for this reason, bariatric and metabolic surgery has been proposed as a method to simultaneously control obesity and MetS. However, in Colombia the results of this intervention are unknown. This study aims to compare metabolic syndrome before and after bariatric surgery in a Colombian population. Methods: Retrospective cohort study conducted in a highly complex institution in Colombia, where comparing the prevalence of metabolic syndrome in patients who underwent bariatric surgery during a 1-year follow-up period, between January 2015 and December 2019. Of these patients, 48 underwent Roux-en-Y gastric bypass, and 32 underwent sleeve gastrectomy by laparoscopic technique. Results: A total of 80 patients were included, of which 67.5% were women and the mean age was 42.8 ± 12.9 years. The most frequent preprocedure comorbidities were arterial hypertension (36.2%), dyslipidemia (32.4%), and sleep apnea (20%). After bariatric surgery, the prevalence of metabolic syndrome decreased from 66.2% to 3.7% (p < 0.05). In addition, a reduction in the Homeostatic Model Assessment for Insulin Resistance score from 77.5% to 22.5% was observed during the follow-up period. HbA1c, creatinine, and thyroid-stimulating hormone, were the only parameters without significant changes. Conclusions: Metabolic and bariatric surgery is an effective treatment for weight reduction, with a high impact in reducing the prevalence of metabolic syndrome and insulin resistance in the short and medium term in the Colombian population.

Factors associated with long COVID syndrome in a Colombian cohort.

Introduction: After acute phase of SARS-CoV-2 infection, some patients persist with clinical symptoms, a phenomenon known as Long COVID syndrome. It is necessary to understand the factors associated with the persistence of these symptoms to develop individualized preventive approaches and effectively address this challenge. Objective: To determine the factors associated with the persistence of symptoms six months after COVID-19 infection. Materials and methods: A ambidirectional cohort, single-center study, that included individuals previously diagnosed with COVID-19 by real-time polymerase chain reaction (PCR) positive test, who were followed for a period of six months. Univariate, bivariate and a multivariate binomial regression model were performed to determine risk factors associated with the persistence of COVID-19 symptoms at the six months of follow-up. Results: The prevalence of long COVID syndrome was 47%. Age demonstrated no significant association with Long COVID (RR 0.999 [95% CI 0.996-1.002]); however, female sex (RR 1.148 [95% CI 1.038-1.268]), requirement of mechanical ventilation (RR 1.278 [95% CI 1.050-1.555]), presence of Chronic Obstructive Pulmonary Disease (COPD) (RR 1.340 [95% CI 1.104-1.626]), Rheumatic Disease (RR 1.259 [95% CI 1.055-1.504]) and the Hospitalization Type: General Hospitalization (RR 1.247 [95% CI 1.090-1.427]) and ICU Hospitalization (RR 1.490 [95% CI 1.221-1.818]) were significantly associated with the persistence of symptoms at the six month of follow-up. Conclusion: Female sex, presence of COPD, rheumatic disease, hospitalization type and requirement of mechanical ventilation during index infection were identified as significant risk factors for the diagnosis of Long COVID. These findings emphasize the importance of addressing Long COVID syndrome in terms of prevention and management, taking these risk factors into consideration.

Persistencia simultánea del conducto uraco y onfalomesentérico en un paciente adulto, reporte de caso / Simultaneous persistence of the urachus and vitelline ducts in an adult patient, case report / Persistência simultânea de úraco e do ducto onfalomesentérico em um paciente adulto: relato de caso

Introducción. La patología umbilical es un tema frecuente en el ámbito pediátrico, la presentación clínica de una fístula umbilical hace pensar en dos patologías mencionadas en la literatura de manera independiente; la primera es la persistencia del conducto onfalomesentérico y la segunda es la persistencia del remanente del uraco producto del fracaso en el cierre de las estructuras embrionarias. Su presencia en adultos es infrecuente y no existen datos estadísticos acerca de su presentación conjunta en población pediátrica o adulta, solo algunos pocos reportes de caso. El diagnóstico se basa principalmente en la sospecha clínica, depende en gran manera del examen físico al evidenciar secreción a través del ombligo al realizar esfuerzos o maniobras de Valsalva. Objetivo. Mostrar un caso infrecuente de la presentación simultánea del conducto de uraco y onfalomesentérico en un paciente adulto. Reporte de caso. Paciente femenina de 24 años de edad con antecedentes de infecciones urinarias y celulitis periumbilicales a repetición. Se sospecha un conducto persistente onfalomesentérico por lo que es sometida a un procedimiento quirúrgico en el que se encontró incidentalmente la persistencia simultánea del conducto onfalomesentérico y persistencia del uraco. Discusión. La persistencia del conducto onfalomesentérico o la persistencia del uraco de forma individual es poco frecuente en adultos, y es aún más raro la persistencia simultánea de ambos conductos; la presencia simultánea de ambos conductos es reportada principalmente en menores de dos años. Conclusiones. La persistencia de estos conductos es rara en adultos y representa un reto diagnóstico para el clínico.

Introduction. Umbilical pathology is a common topic in the pediatric sphere. The clinical presentation of an umbilical fistula leads to the consideration of two pathologies independently reported in literature. The first is a persistent vitelline duct and the second is a persistent urachal remnant as a result of the embryonic structures' failure to close. They are uncommon in adults and there are no statistical data about their presentation together in the pediatric or adult population, only very few case reports. The diagnosis is mainly based on clinical suspicion. It largely depends on a physical examination noting secretion through the navel when straining or performing Valsalva maneuvers. Objective. Show an uncommon case of the simultaneous presentation of the urachus and vitelline ducts in an adult patient. Case report. Female patient aged 24 years with a background of repeated urinary tract infections and periumbilical cellulitis. A persistent vitelline duct is suspected. Therefore, the patient is subject to a surgical procedure in which the simultaneous persistence of the vitelline duct and the urachus was found incidentally. Discussion. The persistence of the vitelline duct or the persistence of the urachus individually is uncommon in adults, and the simultaneous persistence of both ducts is even rarer. The simultaneous presence of both ducts is reported mainly in infants aged under two years. Conclusions. The persistence of these ducts is rare in adults and poses a diagnostic challenge for clinicians.

Introdução. A patologia umbilical é um tópico frequente no cenário pediátrico; a apresentação clínica de uma fístula umbilical faz pensar em duas patologias mencionadas na literatura de forma independente; a primeira é a persistência do ducto onfalomesentérico e a segunda é a persistência do úraco como resultado da falha no fechamento das estruturas embrionárias. É pouco frequente sua presença em adultos e não há dados estatísticos sobre sua apresentação conjunta em população pediátrica nem adulta, apenas alguns poucos relatos de caso. O diagnóstico baseia-se principalmente na suspeita clínica, dependendo em grande parte do exame físico ao evidenciar uma secreção pelo umbigo quando realizar esforço ou manobra de Valsalva. Objetivo. Mostrar um caso infrequente de apresentação simultânea do úraco e ducto onfalomesentérico em um paciente adulto. Relato de caso. Paciente do sexo feminino, 24 anos, com histórico de infecções urinárias e celulite periumbilical recorrentes. Suspeita-se de um ducto onfalomesentérico persistente, portanto ela é submetida a um procedimento cirúrgico no qual encontrou-se a persistência do ducto onfalomesentérico e a persistência de úraco simultaneamente. Discussão. A persistência do ducto onfalomesentérico e a persistência de úraco individualmente é rara em adultos, e a persistência simultânea de ambos os ductos é ainda mais rara; esta presença simultânea é relatada principalmente em crianças menores de dois anos de idade. Conclusão. A persistência desses ductos é rara em adultos e representa um desafio diagnóstico para o profissional de saúde clínico.

Urticaria pigmentosa en el adulto / Urticaria pigmentosa in adult

La urticaria pigmentosa es una de las formas más comunes de las mastocitosis, las cuales corresponden a una serie de procesos caracterizados por un aumento anormal de los mastocitos en diversos órganos y tejidos corporales. En la urticaria pigmentosa la manifestación es exclusiva de la piel, caracterizada por la presencia de lesiones maculopapulares de 2.5 a 5 mm de diámetro, de un color que puede oscilar entre rojo y café, distribuyéndose generalmente en tronco y extremidades respetando palmas y plantas. Cerca de la mitad de los lesiones presenta rubor localizado, prurito y ampollas. Su incidencia y prevalencia son desconocidas; sin embargo, su aparición es más común en niños que en adultos. El diagnóstico depende en gran manera de un adecuado examen físico complementado con estudios de laboratorio e histopatología. El tratamiento de elección constituye la administración de antihistamínicos orales. [Ávila JA, Cala JC, Gelvis JA, Torres V, Mosquera H. Urticaria pigmentosa en el adulto. MedUNAB 2012; 15:63-67].

Urticaria pigmentosa is one of the most common forms of mastocytosis, which correspond to a series of processes characterized by an abnormal increase of mast cells in different organs and tissues. Urticaria pigmentosa has an unique manifestation in the skin, characterized by maculopapular lesions 2.5 to 5 mm in diameter, of a color that can range from red and brown, usually distributed on the trunk and limbs respecting the palms and soles. Half of the lesions presented blush on a specific site, pruritus and blisters. The incidence and prevalence are unknown but their appearance is more common in children than in adults. Diagnosis depends on an properly physical examination with laboratory test and histopathological analysis. The treatment of choice is the administration of oral antihistamines.
