Clinical outcomes of patients with heart failure and atrial fibrillation: Experience from an outpatient heart failure clinic in Colombia.

Background: Heart failure (HF) can coexist with atrial fibrillation in up to 60 % of cases, increasing rates of hospitalizations and death. This study analyzed the clinical characteristics, treatment, hospitalization, and mortality of patients with HF and atrial fibrillation based on left ventricular ejection fraction (LVEF).

Methods: A retrospective cohort study included patients from an outpatient HF clinic at Medellín (Colombia) between 2020-2022.

Balance in Transition: Unraveling the Link Between Menopause and Vertigo.

The onset of menopause, marked by hormonal fluctuations and a decline in estrogen levels, is suggested to be linked to increased susceptibility to vestibular disturbances. Estrogen, beyond its established association with reproductive physiology, plays modulatory roles in various physiological systems, including neurosensory function. The vestibular system, crucial for balance and spatial orientation, is influenced by hormonal changes during menopause, potentially contributing to the emergence of vertigo symptoms.

INJURY EPIDEMIOLOGY IN BEACH TENNIS: INCIDENCE AND RISK FACTORS.

Introduction: Due to the growing increase in beach tennis practice in Brazil and the lack of studies on the injuries that occur in this sport, it has become necessary to develop more research on the subject.

Objective: to identify risk and protection factors for injuries in beach tennis, in order to generate prevention strategies for musculoskeletal injuries.

Method: A cross-sectional epidemiological study, level 3 of evidence, was carried out through an electronic form with 698 Beach Tennis players, who answered questions about their relationship with the practice of the sport and occurrences of injuries.

Evaluation of genotoxicity after acute and chronic exposure to 2,4-dichlorophenoxyacetic acid herbicide (2,4-D) in rodents using machine learning algorithms.

2,4-Dichlorophenoxyacetic acid (2,4-D) is one of the most widely used herbicides in the world, but its mutagenic and carcinogenic potential is still controversial. We simulated environmental exposure to 2,4-D, with the objective of evaluating the genotoxic effect of acute and chronic exposure to 2,4-D in rodents. We also evaluated the performance of machine learning algorithms in detecting differences in exposure groups through recognition performed from genotoxic characteristics.

Cochlear dysfunction and microvascular complications in patients with type 1 diabetes mellitus.

Sensorineural hearing impairment has been associated with DM, and it is probably linked to the same pathophysiological mechanisms as well-established in microvascular diabetes complications. The study of otoacoustic emissions (OAEs) is useful to identify subclinical cochlear dysfunction. Therefore, the aim of this study was to evaluate the association between abnormal OAEs responses, diabetic kidney disease (DKD) and diabetic cardiac autonomic neuropathy (CAN).
