Article Synopsis
  • Parkinson's disease (PD) is a progressive disorder marked by the loss of dopamine-producing neurons, affecting movement and leading to symptoms like catalepsy and impaired gait.
  • This study examined the effects of aminophylline, an adenosine receptor antagonist, in a PD model induced by haloperidol in mice, showing that it can reduce catalepsy but not fully restore normal gait patterns.
  • The results suggest significant adenosine interactions within the basal ganglia and underscore the potential for new treatments targeting these pathways to improve motor function in PD patients.

Article Synopsis
  • The study assesses the effectiveness and challenges of Evidence Centers (NEvs) in Brazil's Evidence-Informed Policy Network (EVIPNet) through a mixed methods approach, including a comprehensive questionnaire for NEv coordinators.
  • Findings indicate a strong capacity for acquiring and assessing evidence among NEvs, but a significant gap in adapting and applying that evidence.
  • Key barriers to implementation were identified, including financial constraints, integration within networks, institutional demand, adaptive capacity, and the need for improved communication of research findings to local stakeholders.

Article Synopsis
  • The study aimed to identify factors contributing to the likelihood of tuberculosis treatment discontinuation among patients in an outpatient setting in Brazil.
  • Researchers followed 148 patients over seven years and found that smoking, drug use, and a high abandonment risk score significantly increased the chances of discontinuing treatment.
  • The results indicated that smoking and undergoing retreatment were key independent risk factors for treatment abandonment, highlighting the importance of targeting patients at higher risk to improve treatment adherence.

Background: Annexins are a group of conserved proteins which exert several regulatory functions on various cellular activities. Increased frequency and levels of antibodies against annexin V have already been observed in several autoimmune diseases including systemic sclerosis (SSc), but their role as a vascular biomarker is unknown. The aim of this study was to determine the serum levels and the dynamical behavior of anti-annexin V antibodies over a 24 months follow-up in patients with SSc.

Objective: This study investigated whether the presence of care workers who completed a specialization course on family health was associated with improved care and maternal and child health indicators in municipalities in the state of Mato Grosso do Sul, Brazil.

Methods: Negative binomial regression models with fixed effects were used for the 79 municipalities in the state of Mato Grosso do Sul, with repeated observations for the period 2009-2015. For our reference, the parameter "number of professionals who completed the course" calculated the proportion of professionals who completed the course, and was divided by the total number of primary health care professionals in the municipality to create a ratio.

The aim of this study was to evaluate the effects of two gamma-amino butyric acid (GABA)a receptor antagonists on motor behavioral tasks in a pharmacological model of Parkinson disease (PD) in rodents. Ninety-six Swiss mice received intraperitoneal injection of Haloperidol (1 mg/kg) to block dopaminergic receptors. GABAa receptors antagonists Bicuculline (1 and 5 mg/kg) and Flumazenil (3 and 6 mg/kg) were used for the assessment of the interaction among these neurotransmitters, in this PD model.

Hydrogen sulfide (HS), an endogenous gaseous mediator, modulates many physiological functions in mammals but evidence of its involvement in emotional and behavioral aspects is currently scarce. We hypothesized that this gas plays a modulatory role in behavioral parameters in rats submitted to tests (for 5min) in the open field (OF) and elevated plus-maze (EPM - test and retest). Male Wistar rats (200-250g) were intraperitoneally injected with saline or NaS (a HS donor; 4, 8 and 12mg/kg) either once or for 8days, and submitted to the OF test or to the EPM test and retest.
