Sarcopenia prevalence did not increase in women undergoing gastric bypass despite weight loss

Graphic with number of patients with sarcopenia parameters in the bariatric and control groups (A) and in bariatric and control groups based on sarcopenia diagnosis (B)

Women (18-65 years old) who underwent bariatric surgery (BG) ≥ 2 years and reached stable weight ≥ 6 months, were investigated in an observational, cross-sectional study for sarcopenia’s presence. Patients subjected to Roux-en-Y gastric bypass did not show increased sarcopenia prevalence in comparison to non-operated women with obesity, despite the significant weight loss. Read More →

Sequencing of the first case of the monkeypox virus in Brazil

Genome sequencing of the B.1 lineage

Monkeypox virus, a zoonotic virus endemic to the African continent, has been reported in 33 non-endemic countries since May 2022. We report an almost complete genome of the first confirmed case of MPXV in Brazil. Shotgun metagenomic sequencing was completed in 18 hours, from DNA extraction to consensus sequence generation.

Impact of semioccluded vocal tract exercises and choral singing in congenital GH deficiency’s subjects

Isolated growth hormone deficiency (IGHD) individuals report normal general quality of life but rate their Voice-Related Quality of Life (V-RQOL) as low. Voice therapy with semioccluded vocal tract exercises and choral training can markedly improve V-RQOL scores, voice self-assessment and auditory-perceptual analysis in IGHD subjects, although GH replacement therapy is not widely accepted.

Brazilian Medical Societies propose a new obesity classification based on weight history

In the new obesity classification, individuals losing a specific proportion of weight are classified as having “reduced” or “controlled” obesity. This classification could help disseminate the concept of clinical benefits derived from modest weight loss, allowing subjects with obesity and their health care professionals to focus on strategies for weight maintenance instead of further weight reduction.

Canagliflozin seems to be more potent in reducing glycated hemoglobinand and body weight in patients with type 2 diabetes

Graph

Among the different doses of gliflozins commercially available in Brazil, Canagliflozin 300 mg had the greatest benefit in terms of body weight reduction, however, results were not different from empagliflozin 25 mg and dapagliflozin 10 mg. It’s not worthwhile to increase gliflozins doses with the intent to further decrease glycated hemoglobin or body weight. Read More →

COVID-19 Affects Perioperative Morbidity and Mortality in Patients Requiring Cardiovascular Surgery

Infographic. Title: COVID-19 Affects Perioperative Morbidity and Mortality in Patients Requiring Cardiovascular Surgery

A retrospective Brazilian multicenter cohort study with 104 patients investigated how COVID-19 affects the perioperative period of cardiovascular surgery. Patients with a positive RT-PCR test within ten days before or after surgery and those presenting with positive RT-PCR test > 10 days after surgery showed significantly higher postoperative complications and death.

The prognosis of differentiated thyroid cancer is not affected by pregnancy

Pregnancy had no impact on the natural course of differentiated thyroid cancer. Disease progression after pregnancy was limited and probably related to more aggressive disease and higher risk stratification at diagnosis. Still, mild disease progression may have occurred asymptomatically in some patients. Read More →

Multifocality and LN metastasis are independent risk factors for incomplete response in TMC patients

This was a retrospective study that aimed at identifying possible risk factors associated with an incomplete response to therapy in thyroid microcarcinoma (TMC) treated with total thyroidectomy, with or without radioactive iodine (RAI) therapy, reclassified according to the response to treatment into “favorable” (excellent/indeterminate) or “unfavorable” (biochemical/structural incomplete) responses.

Results from the ELSA-Brasil trial shows the incidence of thyroid diseases in the country

Results from ELSA-Brasil trial showed a high incidence of hypothyroidism, which is compatible with a country with a more-than-adequate iodine intake. The low women: men ratio of the incidence of thyroid dysfunction highlights the importance of the diagnosis of thyroid diseases among men in the country. Read More →
