Calafate is a native barberry of Patagonia, used in culinary and medicinal practices since ancient times. The aim of this work was to analyze the ability of lactic acid bacteria (LAB) isolated from calafate fruits and flowers, to increase the phenolic compound concentration and antioxidant capacity as well as to inhibit metabolic-related enzymes in fermented calafate juices. The sensory attributes of the selected fermented juice were also analyzed.

Purpose: To describe the characteristics of the initial public health training for speech-language-hearing therapists in Northeastern Brazil.

Methods: The research was based on the curricular framework of public higher education institutions in the Northeast. The analysis approached each institution's general speech-language-hearing program data (state where it is located, total course load, and most recent curricular framework reformulation) and specific data on public health courses (their individual course load, the term when it is offered, syllabus content, whether it was theoretical, practical, both, or internship, and whether it was required or elective).

Although it has been suggested that increased arterial stiffness is linked to exaggerated blood pressure (BP) from brief moderate exercise, it is not clear whether this occurs in older adults with and without hypertension. This study investigates whether the immediate post-exercise systolic BP following brief moderate exercise is associated with arterial stiffness in older females with different BP status. This cross-sectional study included 191 older females aged 60-80 years without known cardiovascular disease (CVD).

Objective: Professionals working in intensive care units (ICUs) during the COVID-19 pandemic have been exposed to stressful situations and increased workload. The association between symptoms of traumatic stress disorders, substance abuse and personal/occupational characteristics of Brazilian COVID-19-ICU workers is still to be addressed. Our aim was to evaluate the prevalence of those conditions and to find if those associations exist.

Objective: Multiple factors have been identified as causes of intracranial compliance impairment (ICCI) among patients with obesity. On the other hand, obesity has been linked with worst outcomes in COVID-19. Thus, the hypothesis of severe acute respiratory syndrome (SARS) conducing to cerebral hemodynamic disorders (CHD) able to worsen ICCI and play an additional role on prognosis determination for COVID-19 among obese patients becomes suitable.

Herein, we explored the associations of pre-pandemic COVID-19 physical activity (PA), sedentary behavior (SB) and cardiorespiratory fitness (CRF) with mental health and quality of life in older adults with hypertension. Objectively measured PA and SB, perceived stress, depression symptoms, and quality of life were assessed before and during the pandemic in seventeen older adults with hypertension. CRF was assessed before the pandemic by cardiopulmonary exercise testing.

: One of the possible mechanisms by which the new coronavirus (SARS-Cov2) could induce brain damage is the impairment of cerebrovascular hemodynamics (CVH) and intracranial compliance (ICC) due to the elevation of intracranial pressure (ICP). The main objective of this study was to assess the presence of CVH and ICC alterations in patients with COVID-19 and evaluate their association with short-term clinical outcomes. : Fifty consecutive critically ill COVID-19 patients were studied with transcranial Doppler (TCD) and non-invasive monitoring of ICC.

Article Synopsis
  • The study aimed to identify the epidemiological profile and key factors influencing morbidity and mortality in high-risk noncardiac surgical patients in Brazil.
  • Conducted as a multicenter observational research, it tracked 904 noncardiac surgical patients in intensive care units over 7 days, noting complication and mortality rates.
  • Results showed a 29.9% complication rate and a 9.6% mortality rate within 28 days post-surgery, with higher risk factors including worse scores on the SAPS 3 and SOFA, longer surgical durations, and the nature of surgeries being emergencies.

In this study, the effect of the ionic cross-linking mode on the ability to control physical properties and in vitro release behavior of the dexamethasone (DEX) drug from chitosan (CS) and chitosan/hydroxyapatite (CS/HA) beads was investigated. CS solutions without and with HA and DEX were dripped into two coagulation solutions, prepared with a non-toxic ionic crosslinker (sodium tripolyphosphate, TPP) and distilled water, one at pH = 9.0 and other at pH = 6.

The Specialized Dental Clinics (SDCs) represent the first government initiative in Latin America aimed at providing specialized oral health services. This study sought to evaluate the organizational accessibility to specialized oral health care services in Brazil and to understand the factors that may be associated with accessibility from the user's perspective. This epidemiological, cross-sectional and quantitative study was conducted by means of interviews with individuals who sought specialized public oral health services in the city of João Pessoa, Paraíba, Brazil, and consisted of a sample of 590 individuals.

Objective: To identify a possible correlation between teachers vocal intensity and the noise in the classroom, as well as between vocal intensity and the symptoms of vocal tract discomfort before and after classes.

Methods: 27 Elementary School I teachers participated in the study. We used the questionnaires "Vocal Production Condition of the Teacher" and "Vocal Tract Discomfort Scale - VTD" which were applied before and after the class.

The open process used to ferment sugar cane juice or molasses to produce ethanol fuel is prone to contamination by bacterial cells of different species, in particular Lactobacilli. The situation can be exacerbated by the emergence of resistant cells to industrial antibiotics that are normally used to combat this contamination. In this work, two Lactobacillus vini isolates from ethanol distilleries were identified and found to be resistant to doxycycline, a tetracycline derivative, although sensitive to other antibiotics tested.

Objective: The aim of this study was to estimate the prevalence of signs and symptoms of temporomandibular disorders (TMD) in patients with primary headaches attended in a tertiary neurology ambulatory.

Method: Authorized by the Ethics Committee, the present cross-sectional study was conducted with a random sample of patients screened for orofacial pain and primary headaches at a tertiary hospital in Northeast of Brazil.

Results: The sample consisted in 42 patients with primary headache, 59.

Background: There is increasing interest in using prediction models to identify patients at risk of readmission or death after hospital discharge, but existing models have significant limitations. Electronic medical record (EMR) based models that can be used to predict risk on multiple disease conditions among a wide range of patient demographics early in the hospitalization are needed. The objective of this study was to evaluate the degree to which EMR-based risk models for 30-day readmission or mortality accurately identify high risk patients and to compare these models with published claims-based models.

Background: Multi-resistantmicroorganisms such as Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa, Candida tropicalis e Candida krusei are the main causes of microbial infections. Padina sanctae-crucis is a seaweed often used to check the contamination of ecosystems by materials such as heavy metals, but studies of the antimicrobial activity of the same seaweed were not found.

Methods: The tests for the minimum inhibitory concentration and modulation of microbial resistance, with the use of ethanolic and methanolic extracts of Padina Sanctae-cruces combined with drugs of the class of aminoglycosides and antifungal were used to evaluate the activity against the cited microorganisms.

Four strains of lactic acid bacteria isolated from cachaça and alcohol fermentation vats in Brazil were characterised in order to determine their taxonomic position. Phylogenetic analysis revealed that they belong to the genus Oenococcus and should be distinguished from their closest neighbours. The 16S rRNA gene sequence similarity against the type strains of the other two species of the genus was below 94.
