Gender Differences in COVID-19 Among Liver Transplant Recipients: Results from a Multicenter Brazilian Cohort
Introduction: Existing literature presents varying perspectives on the impact of COVID-19 on liver transplant recipients.However, no research has specifically investigated the role of gender differences in the manifestation of COVID-19 among liver transplant recipients. This study aims to examine the effects of COVID-19 on liver transplant recipients, with a focus on gender differences in disease presentation and progression. Methods: Conducted as a multicenter historical cohort study, this research collected patient records through an online questionnaire. Assessing COVID-related mortality was the main objective. Additionally, demographic, clinical, and laboratory data pertaining to disease presentation and progression werecollected. Results: The study included a total of 283 patients, of whom 76 were female and 206 were male. The median follow-up period for males was 99 days (IQR 38-283), while for females, it was 126 days (IQR 44-291). A higher prevalence of cardiovascular disease was observed in males (p=0.002). Females frequently experienced a loss of smell (p=0.021), whereas males commonly exhibited fever (p=0.031). Levels of ALT and gamma-glutamyl transferase were significantly elevated in males (p=0.008 and 0.004, respectively). Although there was a trend towards increased mortality in males, it did not reach statistical significance. Conclusion: This study is the first attempt to investigate gender differences in COVID-19 among liver transplant recipients. Our findings highlight the need for a comprehensive and personalised approach to treating this patient population and underscore the importance of further elucidating the disease presentation in these individuals
Esplenectomia e ligadura da veia gástrica esquerda na esquistossomose mansônica: efeito sobre a pressão das varizes de esôfago aferida por tecnica não-invasiva
Em ambos os hospitais universitários de Pernambuco, o tratamento de escolha para portadores de esquistossomose hepatoesplênica (EHE) com antecedente de hemorragia digestiva alta (HDA) por rotura de varizes de esôfago (VE) é a esplenectomia associada à ligadura da veia gástrica esquerda (ELGE); porém, o impacto desta cirurgia sobre a pressão das VE, provavelmente, o parâmetro que melhor se correlaciona com o risco de recidiva hemorrágica, ainda não foi estudado. Com a introdução, em nosso meio, de técnica não-invasiva de medição da pressão das VE, isto tornou-se possível, com mínimos riscos, tomando-se o objetivo do presente estudo. A ELGE foi empregada em vinte portadores de EHE com antecedentes de HDA. A pressão das VE foi medida através do método endoscópico não-invasivo do balão pneumático, antes da cirurgia, e estes valores comparados com novas medições realizadas cinco a oito dias após. A pressão nas VE no pré-operatório variou entre 20,0 e 28,7mmHg (média de 24,35± 2,36 mmHg). Não houve correlação da pressão com o calibre das VE. No pós-operatório (PO), observou-se uma queda significante na pressão das VE, que variou entre 14,6 e 21,5 mmHg (média 17,29± 1,75 mmHg, p<0,001). Os resultados do presente trabalho confirmam as idéias que fundamentam a indicação da ELGE em portadores de EHE com antecedente de HDA. Esta cirurgia determina, pelo menos a curto prazo e na ampla maioria dos casos, uma redução na pressão das VE reduzindo o risco de recidiva de HDA
NEOTROPICAL CARNIVORES: a data set on carnivore distribution in the Neotropics
Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non-detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non-governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peer-reviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non-detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio-temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other large-scale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics.
