Metabolic disorders and post-acute hospitalization in black/mixed-race patients with long COVID in Brazil: A cross-sectional analysis.

BACKGROUND: Although low-middle income countries have been disproportionately affected by the COVID-19 pandemic, there is scarce information about the impact of long COVID on their population. This study aimed to evaluate long COVID symptomatology, complications (hospital readmission and metabolic disorders), and main clinical features that impact Quality of Life (QoL). METHODS: This cross-sectional study provides a detailed clinical and laboratory picture of individuals who presented residual symptoms after mild to severe acute COVID-19. Between Aug-2020 to Sep-2021, long COVID patients were evaluated in a reference center for long COVID in Bahia State, Brazil. The EQ-5D-5L questionnaire accessed QoL. RESULTS: A total of 1164 (52 ±13.4 years, 57% female, 88% black/mixed-race) were evaluated 2.3 [IQR = 1.6-3.7] months after mild (n = 351, 30.2%), moderate (338, 29.0%) or severe (475, 40.8%) acute illness. Dyspnea (790, 67.9%), fatigue (738, 63.5%), and chest pain (525, 42.9%) were the most frequent residual symptoms regardless of acute severity, affecting the QoL of 88.9% of patients (n/N-826/925), mainly the domains of anxiety/depression and pain/discomfort. High levels of HbA1c were detected for 175 out of 664 patients (26.6%), 40% of them without a previous diagnosis of diabetes mellitus. Of note, hospital admission one-to-three months after the acute phase of disease was required for 51 (4.4%) patients. CONCLUSION: In this majority-black/mixed-race population, long COVID was associated with post-acute hospitalization, newly diagnosed diabetes mellitus, and decreased QoL, particularly in women and regardless of disease severity of acute infection, suggesting important implications for health care system.

Multimorbidity associated with anxiety symptomatology in post-COVID patients.

The COVID-19 pandemic hit individuals with chronic conditions the hardest. It is known that anxiety symptoms are frequent in post-COVID conditions. We want to examine whether multimorbidity is associated with anxiety in post-COVID patients. We reported descriptive statistics from 389 post-COVID patients and perform a linear regression with anxiety symptoms measured using the Hospital Anxiety and Depression (HAD) scale. For each extra chronic condition, there was a mean increase of 0.11 in the HAD-anxiety score. However, there was a reduction for age and being male. These findings can potentially help policy-makers better organize post-COVID health services and improve patients care.

Valor da determinação da atividade da adenosina desaminase no diagnóstico diferencial dos derrames pleurais / Value of determining the activity of adenosine deaminase in the differential diagnosis of pleural effusions

Justificativa: Derrame pleural é um problema frequentemente encontrado na prática clínica. Enquanto o derrame pleural transudativo geralmente não apresenta dificuldade no iagnóstico,as efusões exsudativas necessitam de um diagnóstico diferencial cuidadoso que inclui necessariamente tuberculose e neoplasia metastática para a pleura.Métodos: Num estudo transversal, foram estudados 221 pacientes consecutivos, com derrame pleural persistente e/ou não esclarecido, em um hospital de referência para doenças respiratórias na rede pública estadual, com o objetivo de avaliar a acurácia da determinação da atividade da adenosina desaminase (ADA)...
