Readmissions in Elderly Patients with Heart Failure. A Retrospective Study

Heart failure is a major cause of morbidity and mortality worldwide. The prevalence increases with age and usually progresses, leading to repeated hospital admissions and significant symptom burden for patients. The correct management of these patients may decrease readmissions and increase quality of life. Our aim is to compare elderly patients with and without 1-year readmissions in an internal medicine ward, particularly in terms of mortality. Retrospective study, consulting patient’s clinical records, with a diagnosis of heart failure. The patients were characterized and divided in groups: with (wR) and without readmission (woR) within 1 year. Mortality was the primary outcome. Eighty-nine patients were included; 60 woR and 29 wR. There was no gender dif ference between groups, the wR group had older patients. The most frequent comor bidities included atrial fibrillation, hyper tension and chronic renal failure stage 3 or higher. The most frequent cause of hospitalization was heart failure due to insufficient therapy or natural progression of the dis ease. The etiology of heart failure was mainly hypertensive and ischemic. The wR group had more patients classified as NYHA >III . In relation to the primary outcome; mortality at 12 months was higher in the group with repeated admissions . The characterization of this population allows us to highlight the causes of decompensation and to review medication in order to increase the quality of life.info:eu-repo/semantics/publishedVersio

Tuberculosis Infection in HIV Vs Non‐HIV Patients

Objectives: Tuberculosis (TB) is the most common opportunistic infection and cause of mortality among people living with HIV, and it is possible that it may also influence the evolution of the HIV infection. We assessed the differences between HIV-positive and -negative people infected with TB. Methods: The present study is a cross-sectional retrospective study by electronic record revision. We included patients admitted to a tertiary hospital with a diagnosis of TB between 2011 and 2016, comparing those with HIV coinfection with non-HIV patients, according to demographic and clinical characteristics. Results: This study included 591 patients, of whom 32% were HIV-coinfected. HIV-TB patients were younger, with a predominance of male gender. Considering TB risk factors, there was a higher prevalence of homelessness and intravenous drug use in the HIV group. In the non-HIV group, direct contact with other patients with TB and immunosuppression were more prevalent. Relative to TB characteristics, the HIV-coinfected group presents with a higher prevalence of disseminated disease and a higher occurrence of previous TB infection. Cancer was the most frequent cause of immunosuppression in the HIV group and the number testing positive for TB via microbiological culture was lower. Assessment of microbiological resistance and in-hospital mortality showed similar numbers in both groups. Conclusions: There are few papers comparing clinical course of TB between HIV-infected and non-infected patients. Our study differs from others in the literature as we focused on a country with middling incidence of TB and further characterized the differences between HIV-infected and non-infected patients which can contribute to the management of these patients.info:eu-repo/semantics/publishedVersio

Nonspecific Skin Reactivity in Epidemiological Studies

Os testes cutâneos por prick constituem o método diagnóstico de eleição no estudo da sensibilização alergénica, sendo no entanto influenciados por diversos factores. Não se encontram disponíveis dados sobre a quantificação da reacti-vidade cutânea inespecífica em estudos populacionais pediátricos, incluindo amostras de raças diversas. Objectivo: Avaliar e correlacionar a reactividade cutânea à histamina em crianças de diferentes raças,bem como a possível influência de factores como o sexo e a atopia. Material e Métodos: Englobado no Estudo Português de Doenças Alérgicas na Criança (PAC Study), foram estudadas 1710 crianças em idade escolar (6 a 12 anos), 244 de raça Negra na República de Cabo Verde, 756 Caucasianas na Ilha da Madeira e 710 de raça Chinesa em Macau. A todas as crianças foram efectuados testes cutâneos por prick com aeroalergenos, utilizando como referência positiva um extracto de histamina a 10mg/ml (Merck Allergopharma). Foi efectuada análise comparativa do diâmetro médio da pápula induzida pela histamina

Severity of cardiovascular disease outcomes among patients with HIV is related to markers of inflammation and coagulation

Background-In the general population, raised levels of inflammatory markers are stronger predictors of fatal than nonfatal cardiovascular disease (CVD) events. People with HIV have elevated levels of interleukin-6 (IL-6), high-sensitivity C-reactive protein (hsCRP), and D-dimer; HIV-induced activation of inflammatory and coagulation pathways may be responsible for their greater risk of CVD. Whether the enhanced inflammation and coagulation associated with HIV is associated with more fatal CVD events has not been investigated. Methods and Results-Biomarkers were measured at baseline for 9764 patients with HIV and no history of CVD. Of these patients, we focus on the 288 that experienced either a fatal (n=74) or nonfatal (n=214) CVD event over a median of 5 years. Odds ratios (ORs) (fatal versus nonfatal CVD) (95% confidence intervals [CIs]) associated with a doubling of IL-6, D-dimer, hsCRP, and a 1-unit increase in an IL-6 and D-dimer score, measured a median of 2.6 years before the event, were 1.39 (1.07 to 1.79), 1.40 (1.10 to 1.78), 1.09 (0.93 to 1.28), and 1.51 (1.15 to 1.97), respectively. Of the 214 patients with nonfatal CVD, 23 died during follow-up. Hazard ratios (95% CI) for all-cause mortality were 1.72 (1.28 to 2.31), 1.73 (1.27 to 2.36), 1.44 (1.15 to 1.80), and 1.88 (1.39 to 2.55), respectively, for IL-6, D-dimer, hsCRP, and the IL-6 and D-dimer score. Conclusions-Higher IL-6 and D-dimer levels reflecting enhanced inflammation and coagulation associated with HIV are associated with a greater risk of fatal CVD and a greater risk of death after a nonfatal CVD even

A well-kept treasure at depth: precious red coral rediscovered in Atlantic deep coral gardens (SW Portugal) after 300 years

The highly valuable red coral Corallium rubrum is listed in several Mediterranean Conventions for species protection and management since the 1980s. Yet, the lack of data about its Atlantic distribution has hindered its protection there. This culminated in the recent discovery of poaching activities harvesting tens of kg of coral per day from deep rocky reefs off SW Portugal. Red coral was irregularly exploited in Portugal between the 1200s and 1700s, until the fishery collapsed. Its occurrence has not been reported for the last 300 years.info:eu-repo/semantics/publishedVersio

Genomics and epidemiology for gastric adenocarcinomas (GE4GAC): a Brazilian initiative to study gastric cancer

Abstract Gastric cancer (GC) is the fifth most common type of cancer worldwide with high incidences in Asia, Central, and South American countries. This patchy distribution means that GC studies are neglected by large research centers from developed countries. The need for further understanding of this complex disease, including the local importance of epidemiological factors and the rich ancestral admixture found in Brazil, stimulated the implementation of the GE4GAC project. GE4GAC aims to embrace epidemiological, clinical, molecular and microbiological data from Brazilian controls and patients with malignant and pre-malignant gastric disease. In this letter, we summarize the main goals of the project, including subject and sample accrual and current findings
