Background: Parkinson's disease (PD) is a neurodegenerative disorder affecting both sexes, but differences exist between male and female in clinical manifestations, functional impact of symptoms and hormonal influences. Therefore, representativeness of females in PD trials indirectly determines the external validity of the clinical research in this field.

Objective: To estimate the representativeness of female in infusion therapy trials for advanced PD.

The growing expansion of eucalyptus plantations in Brazil and the impact of exotic pests, such as Gonipterus platensis, demand effective, and sustainable biological control strategies. The aim of this study was to assess the pathogenicity of 10 Bacillus thuringiensis (Bt) isolates to neonate Gonipterus platensis larvae, commonly known as the eucalyptus weevil (Coleoptera: Curculionidae) with the specific focus of evaluating their potential to manage this pest while preserving its egg parasitoid, Anaphes nitens. To achieve this, the genomic DNA of the 10 Bt isolates was extracted using the thermal lysis method for molecular characterization of their Cry and Vip proteins.

Background & Aim: Individuals with congenital heart disease (CHD) have reduced cardiorespiratory fitness which is associated with poor prognosis and quality of life. Evidence shows that exercise is effective in the management of adults with CHD. However, uncertainties remain about the safety and efficacy of high-intensity interval training (HIIT) in these patients.

Objective: To describe features and habits of diaper area care and compare the frequency of diaper dermatitis in infants using cloth diapers with those using disposable diapers.

Methods: Questionnaires were administered to families with infants who had not started potty training, to assess the frequency of diaper rash in two groups: babies who use exclusively cloth diapers (CD), and others with exclusively disposable diapers (DD). The hygiene methods of the perineal region and the skin lesions frequency were evaluated.

Background: Despite the well-known positive effects of exercise in patients with coronary artery disease, the best exercise training protocol is still under discussion.

Objective: We performed a systematic review and a meta-analysis to investigate the effects of high-intensity interval training (HIIT) versus moderate-intensity continuous training (MICT) on exercise capacity and health-related quality of life (HRQoL) in patients with coronary artery disease.

Methods: We searched MEDLINE/PubMed, the Cochrane Library EMBASE, and the PEDro database for randomized controlled trials that evaluated the effects of HIIT versus MICT.

This study aimed to assess the impact of nutritional conditions and irradiation parameters on the viability and proliferation of murine preosteoblasts. MC3T3-E1 cells were maintained under standard culture conditions (αMEM supplemented with 10% fetal bovine serum) or nutritional deficit conditions (αMEM without serum) and irradiated or not (control) with an InGaAlP diode laser at wavelengths of 660 nm (red) or 790 nm (infrared), with doses of 1, 4, or 6 J/cm², in a single dose in continuous mode. Cell viability and proliferation were assessed 24, 48, and 72 h after irradiation using the Alamar blue reduction assay.

Background: Erector Spinae Plane Block (ESPB) effectively reduces pain scores for sternotomy in adults. However, evidence is insufficient to assert that the same result occurs in children. The aim of this systematic review and meta-analysis was to evaluate the efficacy of ESPB in pediatric cardiac surgeries.

Article Synopsis
  • * A study analyzing 5 pediatric dermatology books from Brazil and Argentina found that out of 2,471 evaluated photographs, 56% were white, 42% light brown, and there were no representations of dark brown or black skin.
  • * This lack of representation in educational materials is problematic, especially since a significant portion of the Brazilian population identifies as Black, underscoring the need to improve diversity in medical resources to enhance healthcare for all skin types.

  • Clinical practice guidelines (CPGs) for diabetes management face challenges in older adults due to factors like frailty and multiple health issues.
  • * The systematic review analyzed 23 CPGs from the last decade, focusing on HbA1c targets and treatment recommendations for older and frail individuals.
  • * Results showed most CPGs recommend stricter HbA1c targets for healthier older adults, while suggesting more lenient targets for frail individuals, though there's variability in pharmacotherapy advice, especially for frail patients.

Introduction: Neurosonology is a vital paraclinical investigation in modern neurology. However, access to education and certification in neurosonology for neurology residents and young specialists in Europe is challenging, and comprehensive data regarding this topic are scarce. Information regarding difficulties in neurosonology training across Europe may help bring this topic under the spotlight and act as a call for the harmonization of curricula across the continent.

Background: Stereotactic radiosurgery (SRS) is a validated treatment option for cerebral arteriovenous malformations (AVMs), even if a greater knowledge of its potential delayed complications is still being acquired.

Case Description: A 49-year-old man suffered multiple episodes of cerebral hemorrhage in an approximate 10-year follow-up interval in the context of a left central core AVM with deep venous drainage into the internal cerebral veins (Spetzler Martin Grade 4) despite being treated with gamma knife radiosurgery at two separate timepoints, and with an almost complete obliteration confirmed. Approximately 10 years after the first radiosurgery treatment, he developed severe motor aphasia, Grade 3 right hemiparesis, progressive confusion, and memory deficits.

To examine multiple relations between organizational roles, work-family conflict, job satisfaction, mental health, and affective organizational commitment among basic education teachers, a cross-sectional study was conducted with a sample of 438 respondents, to whom the Scale for the Assessment of Psychosocial Stressors in the Workplace (EAEPCL, acronym in Portuguese), the General Job Satisfaction Scale, the General Health Questionnaire (GHQ-12) and the Reduced Affective Organizational Commitment Scale (ECOA, acronym in Portuguese) were applied. Data were analyzed by structural equation modeling and the estimated measurement model indicated convergent and discriminant validity, as well as reliability regarding the latent variables used. Direct effects of conflict and role ambiguity on job satisfaction, common mental disorders (CMD) and affective organizational commitment were observed, as well as indirect effects on the latter two mediated by job satisfaction.

Introduction: Breast cancer is a significant public health problem around the world, ranking first in deaths due to cancer in females. The therapy to fight breast cancer involves different methods, including conventional chemotherapy. However, the acquired resistance that tumors develop during the treatment is still a central cause of cancer-associated deaths.

Polyomaviruses (PyVs) are small double-stranded DNA viruses able to infect species across all vertebrate taxa. In cetaceans, PyVs have been reported only in short-beaked common dolphin (), common bottlenose dolphin () and killer whale (). Herein, we surveyed PyV in 119 cetaceans (29 mysticetes and 90 odontocetes) stranded along the Brazilian coast, from 2002 to 2022, comprising 18 species.

Prior investigation shows that diabetic patients present hypothalamus-pituitary-adrenal (HPA) axis hyperactivity related to impaired negative feedback. This study investigates the effect of Captopril on the overproduction of adrenocorticotropic hormone (ACTH) and its precursor proopiomelanocortin (POMC) in the pituitary gland of male diabetic mice. Diabetes was induced by intravenous injection of alloxan into fasted Swiss-webster mice, and the animals were treated with Captopril for 14 consecutive days, starting 7 days post-diabetes induction.

  • Scientists used a technique called Transcranial Magnetic Stimulation (TMS) to study how our brains control movement and the sounds we hear.
  • They found that TMS can help improve how people tell different sounds apart, showing that it can change how our brains work.
  • Their results suggest that TMS might be a good way to understand brain activity better, especially in how we process different types of sounds.
