First evidence of Tityus confluens Borelli, 1899 (Buthidae) venom altering purine metabolism in rat blood cells.

Purinergic signaling pathways play crucial roles in regulating hemostatic and inflammatory responses, both of which are impacted by scorpion envenomation. Scorpion venoms are complex mixtures of various toxins, such as peptides, enzymes, and nucleotides. Previous research showed that the action of scorpion toxins on the purinergic system stems from their effects on purinergic receptors.

Effects of high-intensity interval and moderate-intensity continuous training on ambulatory blood pressure and cardiovascular outcomes in older adults with hypertension (HEXA Study): study protocol for a randomised trial.

Introduction: Approximately two-thirds of Brazilian older adults have hypertension. Aerobic training is the first-line non-pharmacological therapy for hypertension. However, the effects of different aerobic training approaches on ambulatory blood pressure in older adults are uncertain.

Artificial intelligence applied to bed regulation in Rio Grande do Norte: Data analysis and application of machine learning on the "RegulaRN Leitos Gerais" platform.

Bed regulation within Brazil's National Health System (SUS) plays a crucial role in managing care for patients in need of hospitalization. In Rio Grande do Norte, Brazil, the RegulaRN Leitos Gerais platform was the information system developed to register requests for bed regulation for COVID-19 cases. However, the platform was expanded to cover a range of diseases that require hospitalization.

Increasing Premedication for Neonatal Intubation: A Quality Improvement Initiative.

Introduction: Endotracheal intubation is frequent in the neonatal intensive care unit (NICU) but may result in neonatal distress and instability. Premedication reduces adverse effects, such as hypoxia, bradycardia, and pain. The Specific, Measurable, Achievable, Relevant and Time-Bound aim for this project was to increase premedication use for nonemergent neonatal intubation in a specific NICU from 22% to 80% from March 2021 to May 2023.

Evaluating MicroRNAs as diagnostic tools for lymph node metastasis in breast cancer: Findings from a systematic review and meta-analysis.

Lymph node metastasis (LNM) significantly affects the prognosis and clinical management of breast cancer (BC) patients. This systematic review and meta-analysis aim to identify microRNAs (miRNAs) associated with LNM in BC and evaluate their potential diagnostic and prognostic value. Following PRISMA guidelines, a comprehensive literature search was conducted in PubMed, Web of Science, and SCOPUS databases, to assess the role of miRNAs in LNM BC.

The finger-ring test as an indicator of muscle mass estimated by dual-energy X-ray absorptiometry in an adult community-dwelling population.

Introduction: The finger-ring test (FRT) offers a simple method to screen older adults at increased risk of sarcopenia.

Objective: To investigate the association between the FRT and lean soft tissue mass estimated by dual-energy X-ray absorptiometry (DXA), and to further elucidate the FRT as an indicator of muscle mass, while accounting for potential confounders, in a community-dwelling population.

Materials And Methods: Within this cross-sectional study 430 community-dwelling individuals aged 18 to 79 (286 women (66.

Blockchain in Health Information Systems: A Systematic Review.

In parallel, blockchain technology has gradually proven to be an innovative solution to address this challenge, as its ability to provide an immutable and secure record of transactions offers significant promise for healthcare information management. This systematic review aims to explore the applications of blockchain in health information systems, highlighting its advantages and challenges.

Amplitude-Integrated Electroencephalography: A Readily Available Tool for Neonatologists.

Hypoxic-ischemic encephalopathy (HIE) is a common condition occurring at birth, impairing central nervous system function. Therapeutic hypothermia is beneficial for suspected HIE as it reduces mortality and disability in survivors but not for other types of encephalopathy (e.g.

Historical and practical aspects of macular buckle surgery in the treatment of myopic tractional maculopathy: case series and literature review.

Background: Uncorrected myopia is a leading cause of blindness globally, with a rising prevalence in recent decades. Pathological myopia, often seen in individuals with increased axial length (AXL), can result in severe structural changes in the posterior pole, including myopic tractional maculopathy (MTM). MTM arises from tractional forces at the vitreoretinal interface, leading to progressive macular retinoschisis, macular holes, and retinal detachment (RD).

Methods for causality assessment of idiosyncratic drug-induced liver injury.

The diagnosis of idiosyncratic drug-induced liver injury (DILI) is a challenging task due to the lack of specific features or definitive diagnostic tools. A minimum of clinical and pharmacological information is required, together with laboratory and imaging tests to exclude other causes of liver injury. Several standardized methods have been developed to support clinical judgement and establish causality assessment, the most widely used being the Roussel Uclaf Causality Assessment Method-RUCAM-and structured Expert Opinion.

Solar Tracking Control Algorithm Based on Artificial Intelligence Applied to Large-Scale Bifacial Photovoltaic Power Plants.

The transition to a low-carbon economy is one of the main challenges of our time. In this context, solar energy, along with many other technologies, has been developed to optimize performance. For example, solar trackers follow the sun's path to increase the generation capacity of photovoltaic plants.

Early de-escalation of antibiotic therapy in hospitalized cellular therapy adult patients with febrile neutropenia.

Febrile neutropenia (FN) is an oncologic emergency frequently encountered in hematopoietic cell transplant (HCT) and chimeric antigen receptor (CAR) T-cell therapy patients, which requires immediate initiation of broad-spectrum antibiotics. Data regarding antibiotic de-escalation (DE) in neutropenic patients are limited, and guideline recommendations vary. A clinical protocol for antibiotic DE of broad-spectrum agents was implemented if patients were afebrile after 72 hours and had no clinical evidence of infection.

Objective: We describe the clinical presentation and ocular viral dynamics in patients with Monkeypox virus-related ophthalmic disease (MPXROD).

Methods: In this case series, we investigated five consecutive patients with confirmed mpox, diagnosed through a positive Monkeypox virus (MPXV) Polymerase Chain Reaction (PCR) test and presenting with ocular symptoms. They were referred from the Reference Center for Sexually Transmitted Infections in São Paulo (CRT) to the Uveitis Sector at the Federal University of São Paulo, between August and December 2022.

Control compounds for preclinical drug-induced liver injury assessment: Consensus-driven systematic review by the ProEuroDILI network.

Background & Aims: Idiosyncratic drug-induced liver injury (DILI) is a complex and unpredictable event caused by drugs, and herbal or dietary supplements. Early identification of human hepatotoxicity at preclinical stages remains a major challenge, in which the selection of validated in vitro systems and test drugs has a significant impact. In this systematic review, we analyzed the compounds used in hepatotoxicity assays and established a list of DILI-positive and -negative control drugs for validation of in vitro models of DILI, supported by literature and clinical evidence and endorsed by an expert committee from the COST Action ProEuroDILI Network (CA17112).
