Long-term respiratory outcomes after COVID-19: a Brazilian cohort study.

Objective: To investigate the prevalence and risk factors for persistent symptoms up to 12 months after hospital discharge in COVID-19 survivors. Methods: This prospective cohort study included patients with COVID-19 discharged from a university hospital in Brazil. Follow-up was performed 2, 6, and 12 months after discharge. Lung function tests and chest computed tomography (CT) were performed 2 months after discharge and were repeated if abnormal. The primary outcomes were the symptoms present, work status, and limitations in daily activities. Results: Eighty-eight patients were included. Dyspnea (54.5%), fatigue (50.0%), myalgia, and muscle weakness (46.6%) were the most common symptoms, which decreased over time. Anxiety was frequent (46.6%) and remained unchanged. One year after discharge, 43.2% of the patients reported limitations in daily activities, and 17.6% had not returned to work. Corticosteroid use was significantly associated with dyspnea and limitations in daily activities. Females had an increased risk of fatigue at the 12-month assessment, with marginal significance after multivariable adjustment. Young age and bronchial wall thickening on admission CT were also risk factors for dyspnea at follow-up. The most common lung function abnormalities were reduced diffusion capacity and small airway disease, which partially improved over time. Conclusions: One year after hospital discharge, more than one-third of patients still had persistent COVID-19-related symptoms, remarkable dyspnea, fatigue, and limitations in daily activities, regardless of acute disease severity. Age, female sex, corticosteroid use during hospitalization, and bronchial thickening on admission CT were associated with an increased risk of sequelae.

Are Wealthier Times Healthier in Cities? Economic Fluctuations and Mortality in Urban Areas of Latin America.

Objective: To analyze the relationship between economic conditions and mortality in cities of Latin America. Methods: We analyzed data from 340 urban areas in ten countries: Argentina, Brazil, Chile, Colombia, Costa Rica, Guatemala, Mexico, Panama, Peru, and El Salvador. We used panel models adjusted for space-invariant and time-invariant factors to examine whether changes in area gross domestic product (GDP) per capita were associated with changes in mortality. Results: We find procyclical oscillations in mortality (i.e., higher mortality with higher GDP per capita) for total mortality, female population, populations of 0-9 and 45+ years, mortality due to cardiovascular diseases, malignant neoplasms, diabetes mellitus, respiratory infections and road traffic injuries. Homicides appear countercyclical, with higher levels at lower GDP per capita. Conclusions: Our results reveal large heterogeneity, but in our sample of cities, for specific population groups and causes of death, mortality oscillates procyclically, increasing when GDP per capita increases. In contrast we find few instances of countercyclical mortality.

Esthetics outcomes in patients submitted to pterional craniotomy and its variants: A scoping review.

BACKGROUND: Highly performed nowadays, the pterional craniotomy (PC) has several widespread variants. However, these procedures are associated with complications such as temporalis muscle atrophy, facial nerve frontal branch damage, and masticatory difficulties. The postoperative cranial aesthetic is, nonetheless, the main setback according to patients. This review aims to map different pterional approaches focusing on final aesthetics. METHODS: This review follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Studies were classified through the Oxford method. We searched PubMed/MEDLINE, EMBASE, and Cochrane Library from January 1969 to February 2021 for cohorts and randomized clinical trials that met our inclusion criteria. RESULTS: 1484 articles were initially retrieved from the databases. 1328 articles did not fit the inclusion criteria. 118 duplicates were found. 38 studies were found eligible for the established criteria. 27 (71.05%) were retrospective cohorts, with low evidence level. Only 5 (13.15%) clinical trials were found eligible to the criteria. The majority of the studies (36/38) had the 2B OXFORD evidence level. A limited number of studies addressed cosmetic outcomes and patient satisfaction. The temporal muscle atrophy or temporal hollowing seems to be the patient's main complaint. Only 17 (44.73%) studies addressed patient satisfaction regarding the aesthetics, and only 10 (26.31%) of the studies reported the cosmetic outcome as a primary outcome. Nevertheless, minimally invasive approaches appear to overcome most cosmetic complaints and should be performed whenever possible. CONCLUSION: There are several variants of the classic PC. The esthetic outcomes are poorly evaluated. The majority of the studies were low evidence articles.
