Background: Immunization is a significant public health achievement for the whole world, although the population's adherence to vaccination efforts remains a concern. To address this, Brazil's Ministry of Health introduced the concept of operational microplanning (OM) for high-quality vaccination activities (HQVA) in 2023 to ensure excellence in routine service and campaigns. OM is defined by structured interventions using assertive techniques to enhance the likelihood of covering a broader population previously unprotected from vaccine-preventable diseases.

Understanding the impact of different Candida species on patient outcomes is crucial for effective management and treatment strategies. This study aims to comprehensively analyze the association between Candida species and mortality in documented candidemia. We queried TriNetX, a global research network database, to identify patients diagnosed with candidemia through polymerase chain reaction from 2020 to 2023.

This study explores the potential of polymethoxyflavones (PMFs) and polyacetylated flavones (PAFs) as novel analgesic and anti-inflammatory agents. Eight derivatives, isolated from Gardenia oudiepe bud exudate or semi-synthesized from commercial kaempferol, underwent evaluations in various in vivo, in vitro, and in silico models. Acetic acid-, formalin-induced pain, and hot-plate tests were conducted in mice (n = 6).

Article Synopsis
  • The study investigates the anti-ulcer effects of hydroalcoholic extract (HETp) and its active component parthenolide (PTL) against gastric ulcers induced by ethanol and piroxicam.
  • Results showed that both HETp and PTL significantly reduced ulcer formation, with additional histological support confirming their effectiveness.
  • The protective effects involve various mechanisms, including the influence of nitric oxide, adrenergic receptors, and prostaglandins, while also enhancing antioxidant levels and reducing harmful enzyme activity.

This study evaluated the glass fibre post (GFP) removal using three different protocols with ultrasonic tips. Thirty-six extracted single-rooted teeth were endodontically treated and cemented with a 10-mm GFP. Three protocols were used for GFP removal: 20 s activated with cooling, 20 s activated without cooling and 40 s activated without cooling.

The incidence of thyroid cancer is increasing globally, but mortality rates have remained steady. Many patients with thyroid cancer have low-risk, nonmetastatic intrathyroidal tumors smaller than 2 cm. Active surveillance has shown benefits in these patients, but the adoption of this approach remains below standard in Latin America.

Objective: To compare the long-term medical costs of active surveillance (AS), partial thyroidectomy (PT), and total thyroidectomy (TT) in patients with low-risk papillary thyroid microcarcinoma (PTMC) receiving care covered by the Brazilian Public Health System.

Materials And Methods: After reviewing AS cohorts and our own data, we created a model of AS, PT, and TT flow care for low-risk PTMC over 10, 20, and 30 years. The medical costs included those associated with diagnosis, surgery, and follow-up.

This study aimed to evaluate the microbiological quality of coconut water sold from street carts equipped with cooling coils or refrigerated at bakeries in the Grande Vitória Region, Brazil. Additionally, it assessed the phenotypic and genotypic antimicrobial resistance profiles of isolated enterobacteria. The results indicated that coconut water sold at street carts had lower microbiological quality compared to refrigerated samples, as evidenced by significantly higher counts of mesophilic microorganisms.

Article Synopsis
  • The study investigates the effectiveness of nonsurgical root canal retreatment (NS-RCRT) using 2% chlorhexidine gel and foraminal enlargement techniques in improving periapical healing and success rates compared to traditional methods.
  • A retrospective analysis of 120 teeth from 80 patients showed a high success rate of 92.5% over an average follow-up of 30 months, with radiographic repair as the main influencing factor.
  • The findings suggest that the new NS-RCRT approach may serve as a viable alternative to tooth extraction, warranting further prospective research to confirm its benefits.

Introduction: Active surveillance (AS) is increasingly recognized as an appropriate strategy for selected patients with papillary thyroid microcarcinomas (PTMC). However, some factors, including physician-related ones, hinder its widespread adoption.

Methods: To explore the prevailing barriers and the impact of information on attitudes towards AS implementation, we developed a questionnaire that was completed before and after reading a simple information leaflet by 317 doctors working in different work environments.

  • Lisdexamfetamine dimesylate (LDX), a drug for ADHD, hasn't been studied for its potential toxic effects on kidneys, which is the focus of this research.
  • The study involved male Wistar rats treated with LDX to assess kidney health through various parameters including cell death, inflammation, and oxidative stress.
  • Findings revealed increased cell death and inflammation in the kidneys of LDX-treated rats, but a normal functioning antioxidant system, indicating significant renal changes during the peripubertal period.

Introduction: Samples classified as indeterminate correspond to 10-20% of cytologies obtained by fine needle biopsy of thyroid nodules, preventing an adequate distinction between benign and malignant lesions and leading to diagnostic thyroidectomies that often prove unnecessary, as most cases are benign. Furthermore, although the vast majority of patients with differentiated thyroid cancer (DTC) have such a good prognosis that active surveillance is permitted as an initial therapeutic option, relapses are not rare, and a non-negligible number of patients experience poor outcomes. MicroRNAs (miR) emerge as potential biomarkers capable of helping to define more precise management of patients in all these situations.

Three new polyprenylated benzophenone derivatives named burlemarxiones G-I (1-3) were isolated from C. burle-marxii trunks (compound 1) and leaves (compounds 2 and 3), along with the known compound burlemarxione F. Burlemarxione G (1) was isolated after methylation with diazomethane and it is the keto-enol tautomeric pair of burlemarxione F.
