Article Synopsis
  • The study investigates the relationship between muscle sympathetic nervous activity (MSNA) and cerebral blood velocity (CBv) during different physiological conditions in healthy subjects.
  • Using methods like transcranial Doppler ultrasound and microneurography, researchers measured changes in MSNA, mean arterial pressure (MAP), and CBv during isometric handgrip exercise and cold pressor test.
  • Findings indicate that MSNA significantly influences CBv regulation, revealing that both MAP and MSNA dynamically affect cerebral blood flow at rest and during stress tests.

Purpose: Central and peripheral chemoreceptors are hypersensitized in patients with heart failure with reduced ejection fraction. Whether this autonomic alteration occurs in patients with heart failure with preserved ejection fraction (HFpEF) remains little known. We test the hypothesis that the central and peripheral chemoreflex control of muscle sympathetic nerve activity (MSNA) is altered in HFpEF.

Objective: The WHO Safe Childbirth Checklist (SCC) is a promising initiative for safety in childbirth care, but the evidence about its impact on clinical outcomes is limited. This study analysed the impact of SCC on essential birth practices (EBPs), obstetric complications and adverse events (AEs) in hospitals of different profiles.

Design: Quasi-experimental, time-series study and pre/post intervention.

Objectives: To investigate the chemical changes in root dentin submitted to ionizing radiation and how it affects the interaction with resin cements.

Materials And Methods: Forty human premolars were randomly divided into two groups (n = 20): non-irradiated and irradiated. They were randomly subdivided according to the type of resin cement (n = 10): conventional (RelyX ARC, 3 M ESPE) or self-adhesive (RelyX U200, 3 M ESPE).

Purpose: Obstetric adverse outcomes (AOs) are an important topic and the use of composite measures may favor the understanding of their impact on patient safety. The aim of the present study was to estimate AO frequency and obstetric care quality in low and high-risk maternity hospitals.

Design/methodology/approach: A one-year longitudinal follow-up study in two public Brazilian maternity hospitals.

Objective: To evaluate the chemical and mechanical properties of enamel submitted to different in vitro radiation protocols.

Design: Third molars were divided into seven groups (n = 8): non-irradiated (NI); a single dose of 30 Gy (SD30), 50 Gy (SD50), or 70 Gy (SD70) of radiation; or fractional radiation doses of up to 30 Gy (FD30), 50 Gy (FD50), or 70 Gy (FD70). Hemisections were analysed by Fourier transform infrared spectroscopy (FTIR), energy dispersive X-ray spectroscopy (EDS) and Knoop microhardness (KHN) test.

Background: Preeclampsia is a relatively frequent condition during pregnancy and childbirth. The administration of magnesium sulphate as a prophylactic and treatment measure is an evidence-based practice for eclampsia; however, it is not consistently used, compromising the health of pregnant women. This study aimed to assess compliance with recommendations of the International Society for the Study of Hypertension in Pregnancy (ISSHP) for the use of MgSO in pregnant women with preeclampsia, before and after the implementation of the World Health Organization Safe Childbirth Checklist (SCC).

Background: The purpose of this study was to test the hypothesis that a community-based intensive cardiac rehabilitation program could produce positive changes in risk factor profile and outcomes in an at-risk population.

Methods: Participants seeking either primary or secondary coronary artery disease prevention voluntarily enrolled in the 12-week intensive cardiac rehabilitation program. Data were obtained at baseline and 6-12 months after completion of the program.

Decreasing childbirth-related mortality is a current global health priority. The World Health Organization developed the Safe Childbirth Checklist to reduce adverse events in maternal and perinatal care, using simple and effective practices. The current study aims to evaluate adherence to the checklist by professionals in a maternity hospital in Natal, Rio Grande do Norte State, Brazil.

Efficacious patient safety monitoring should focus on the implementation of evidence-based practices that avoid unnecessary harm related to healthcare. The ISEP-Brazil project aimed to develop and validate indicators for best patient safety practices in Brazil. The basis was the translation and adaptation of the indicators validated in the ISEP-Spain project and the document Safe Practices for Better Healthcare (U.

The aim of this study was to investigate occurrence of Toxoplasma gondii in sheep slaughtered in the state of Alagoas, Brazil, by means of different diagnosis techniques. Serum samples and tissues from 100 slaughtered sheep were used. To detect antibodies, the indirect immunofluorescence antibody test (IFAT) was used, and tissues from seropositive animals (cut-off ≥1:64) were submitted to Polymerase Chain Reaction (PCR) and immunohistochemistry (IHC).

Background: Urine is increasingly becoming an attractive biological fluid in clinical practice due to being an easily obtained, non-invasive sampling method, containing proteins and peptides. The aim of this study was to investigate eosinophiluria, urinary eosinophil cationic protein (uECP) and urinary IL-5 (uIL-5) in patients with Lupus Nephritis.

Methods: Seventy-four patients with SLE-20 with clinical and laboratory evidence of lupus nephritis (LN group) and 54 without evidence of renal involvement (non-LN group)-were analyzed regarding eosinophiluria, uECP and uIL-5.

Introduction: Depression during or shortly after hospitalization elevated two to three times the risk of mortality or nonfatal cardiac events, significantly increasing the morbidity and mortality of these patients.

Objective: To assess the impact of revascularization on symptoms of depression in patients with coronary artery disease.

Methods: A prospective cohort study of 57 patients of both sexes undergoing coronary artery bypass grafting between June 2010 and June 2011.

Background: Cardiac rehabilitation improves physical, cognitive and psychosocial functioning, yet services are greatly underutilized with increasing patterns of attrition over time. Tai Chi has been suggested as a possible adjunct to cardiac rehabilitation exercise training.

Aim: To describe differences in physical, cognitive and psychosocial functioning among adults ≥ 45 years old attending phase III cardiac rehabilitation, who have or have not self-selected Tai Chi exercise as an adjunct physical activity.

Although the odontology professional recognizes the existence of norms most of them had not demonstrated to perceive the fair and precise need of clarification. The perception lack displays to some problems as: lack of information on the necessity of accomplishment of periodic medical examinations of the professionals, lack of knowledge in the correct use of the equipment of x-rays, unfamiliarity of the necessity of periodic calibration of the device of x-rays, the inefficiency in the fulfillment of the radiation protection norms, the inadequate use of the equipment of individual protection (EPI) and absence of a manual of norms of the professional activities. Based in these results it can be concluded that the surgeon-dentists do not withhold the necessary knowledge on the norms of radiation protection and the correct use of the equipment of individual protection.

Purpose: There are several ways to propagation of parasitary diseases and how there aren't many bibliographic work about this theme, it was realized a study near to the Natal-RN population, to verify the enteroparasites transmission through the paper money.

Methods: In the Laboratório Parasitologia Clínica was analysed 500 bills of several worths gotten in shops and, concomitantly it was examined samples of a water got from the washed hands of the people who held the money. The methods to realize the parasitologic exams were: Ritchie and Faust et al.
