RESUMO

Severe COVID-19 is associated with a systemic hyperinflammatory response leading to acute respiratory distress syndrome (ARDS), multi-organ failure, and death. Galectin-3 is a ß-galactoside binding lectin known to drive neutrophil infiltration and the release of pro-inflammatory cytokines contributing to airway inflammation. Thus, we aimed to investigate the potential of galectin-3 as a biomarker of severe COVID-19 outcomes. We prospectively included 156 patients with RT-PCR confirmed COVID-19. A severe outcome was defined as the requirement of invasive mechanical ventilation (IMV) and/or in-hospital death. A non-severe outcome was defined as discharge without IMV requirement. We used receiver operating characteristic (ROC) and multivariable logistic regression analysis to determine the prognostic ability of serum galectin-3 for a severe outcome. Galectin-3 levels discriminated well between severe and non-severe outcomes and correlated with markers of COVID-19 severity, (CRP, NLR, D-dimer, and neutrophil count). Using a forward-stepwise logistic regression analysis we identified galectin-3 [odds ratio (OR) 3.68 (95% CI 1.47-9.20), p < 0.01] to be an independent predictor of severe outcome. Furthermore, galectin-3 in combination with CRP, albumin and CT pulmonary affection > 50%, had significantly improved ability to predict severe outcomes [AUC 0.85 (95% CI 0.79-0.91, p < 0.0001)]. Based on the evidence presented here, we recommend clinicians measure galectin-3 levels upon admission to facilitate allocation of appropriate resources in a timely manner to COVID-19 patients at highest risk of severe outcome.

RESUMO

Steroid 21-hydroxylase deficiency accounts for 95% of congenital adrenal hyperplasia (CAH) cases. Newborn screening has allowed for early detection of the disease, and currently, molecular analysis can identify the genotypes of these patients. Phenotype-genotype correlation has been well described in previous studies. In Costa Rica, there is no data about the genetic background of these patients, nor their phenotypic correlation. DESIGN: Observational, retrospective, descriptive study based on the review of patient records who had a diagnosis of CAH and were performed molecular analysis using gene sequencing or MLPA during the period from 2006 to 2018 (N = 58). OBJECTIVE: To describe the clinical and genetic characteristics of CAH patients due to 21-hydroxylase deficiency at the National Children's Hospital "Dr. Carlos Sáenz Herrera", Caja Costarricense de Seguro Social (CCSS) in Costa Rica. RESULTS: 53% (31/58) of the patients were male and 80% (37/46) were born full term; 72% (42/58) had salt wasting phenotype, 9% (5/58) simple virilizing phenotype and 19% (11/58) non-classic phenotype. The most frequent variants were c.292+5G>A in 26% (15/58) of patients and Del/Del in 21% (12/58) of them. CONCLUSIONS: The most frequent mutation in our study population was the c.292+5G>A, which was found in 15/58 patients. This rare variant has only been reported in three other studies so far but as an infrequent mutation in CAH patients. The genetic characteristics of Costa Rican patients differ from what has been documented worldwide and could respond to a founder effect.

RESUMO

Liver injury can result from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection with more than one-third of COVID-19 patients exhibiting elevated liver enzymes. Microvesicular steatosis, inflammation, vascular congestion, and thrombosis in the liver have been described in autopsy samples from COVID-19 patients. Several factors, including direct cytopathic effect of the virus, immune-mediated collateral damage, or an exacerbation of preexisting liver disease may contribute to liver pathology in COVID-19. Due to its immunological functions, the liver is an organ likely to participate in the viral response against SARS-CoV-2 and this may predispose it to injury. A better understanding of the mechanism contributing to liver injury is needed to develop and implement early measures to prevent serious liver damage in patients suffering from COVID-19. This review summarizes current reports of SARS-CoV-2 with an emphasis on how direct infection and subsequent severe inflammatory response may contribute to liver injury in patients with and without preexisting liver disease.

RESUMO

Introducción: como método diagnóstico, la citología por aspiración con aguja fina es, en muchos centros, la primera línea de investigación para las opacidades pulmonares periféricas diagnosticadas por una radiografía simple de tórax.Objetivo: determinar el valor de los indicadores de efectividad de la citología por aspiración con aguja fina en el diagnóstico de cáncer de pulmón de localización periférica.Método: se realizó un estudio observacional analítico transversal en pacientes adultos atendidos en el Servicio de Neumología del Hospital Provincial General Docente Dr. Antonio Luaces Iraola de la provincia Ciego de Ávila, de enero de 2012 a febrero de 2013. El universo coincidió con la muestra: 29 pacientes adultos con sospecha de cáncer de pulmón de localización periférica, diagnosticados en el período antes referido, que cumplieron con los criterios de inclusión del estudio.Resultados: la enfermedad fue más frecuente en los hombres (68,9 por ciento) y las edades más afectadas correspondieron al grupo de 60 a 69 años (51,7 por ciento). La variedad citológica más diagnosticada fue el carcinoma de células no pequeñas (34,4 por ciento) y la forma radiológica de imagen tumoral (79,2 por ciento) prevaleció sobre el resto. Las lesiones más frecuentes fueron las mayores de 2 cm (72,4 por ciento). El neumotórax fue la complicación que se presentó en pacientes con lesiones menores de 2 cm (6,9 por ciento). La sensibilidad y especificidad de la prueba fueron de 90,91 por ciento y 100 por ciento respectivamente; su valor predictivo osciló entre 78 por ciento y 100 por ciento.Conclusiones: se demostró la efectividad diagnóstica del proceder(AU)


Introduction: as a diagnostic method, the cytology for fine-needle aspiration is the fact-finding front line for the pulmonary peripheral opacities diagnosed by a simple chest X-ray.Objective: to determine the value of the cytology effectiveness indicators for fine-needle aspiration in the diagnosis of lung cancer of peripheral location.Method: an observational analytical study was carried out in adult patients of Pneumology Service of the Provincial General Teaching Hospital Dr. Antonio Luaces Iraola in Ciego de Ávila from January 2012 to February 2013.

RESUMO

Introducción: la incidencia y prevalencia de la tuberculosis en la provincia Ciego de Ávila constituye una problemática de salud; por ello se intensificó la búsqueda activa, organizada y sistemática de los grupos de riesgo. Objetivo: determinar la infección por tuberculosis y su asociación con diferentes factores de riesgo, mediante la prueba de la tuberculina. Método: se realizó un estudio observacional analítico transversal en el período de un año en el Policlínico Docente “Antonio Maceo” Área Centro del municipio Ciego de Ávila. Se realizó un muestreo polietápico simple aleatorio en todos los consultorios. La muestra quedó constituida por cinco consultorios, con 600 pacientes adultos que cumplieron los criterios de inclusión. Se calculó la razón de prevalencia con intervalos de confianza para un índice de confiabilidad del 95%. Se aplicó la prueba de la tuberculina, con lectura a las 48 horas, a los pacientes que resultaron negativos se les repitió el proceder a las 8 semanas. Resultados: el hallazgo más relevante fue el predominio del factor de riesgo contactos de tuberculosis con baciloscopia positiva, con 179 pacientes, 23 casos positivos, con una razón de prevalencia de 0.7, estadísticamente significativo en la probabilidad de contraer la enfermedad, y una prevalencia del 2.2, la prueba de tuberculina tuvo conversión a los dos meses en los pacientes que fueron inicialmente negativos. Conclusiones: de los grupos de riesgo, los casos que presentaron infección por tuberculosis fueron: contactos directos, ex reclusos y hacinamiento, éstos a su vez los más propensos a enfermar en un período de 2 años(AU)


Introduction: with the increase in the incidence and prevalence of tuberculosis in Ciego de Avila province and being a health problem; it is necessary to strengthen the active, organized and systematic search for the risk group. Objective: to determine TB infection and its association with various risk factors, by testing the tuberculin. Method: a cross-sectional, observational study in a year period was carried out in “Antonio Maceo” Teaching Policlynic Center Area of Ciego de Ávila. Multistage sampling of all locations by simple random sampling was carried out. The sample was constituted by five offices, with 600 adult patients who met the inclusion criteria. The prevalence ratio with confidence intervals for a reliability index of 95% was calculated. Tuberculin test was applied with reading at 48 hours, and to the negative patients was repeated at 8 weeks. Results: the most significant finding was the prevalence of risk factor, contact smear-positive tuberculosis with 179 patients, 23 positive cases, with a prevalence ratio of 0.7, statistically significant in the probability of contracting the disease, and a prevalence of 2.2. Tuberculin test had a conversion two months later in patients who were initially negative. Conclusions: from the risk groups, the cases that presented tuberculosis infection were: direct contacts, ex-prisoners and overcrowding and these one were more likely to get sick in a period of 2 years(AU)
