We compared the BMI-for-age (BMI/A) trajectory of Brazilian adolescents monitored in the primary health care (PHC) setting based on a simulated scenario. We used a real-life cohort of adolescents monitored by the Food and Nutrition Surveillance System (Sisvan) between 2008 and 2018. The LMS method was employed to estimate the simulated BMI/A evolution curve, assuming that the adolescents maintained the conditions observed during their first assessment (simulation curve).

In the manufacturing of some sectors, such as marble and brick, certain byproducts, such as sludge, powder, and pieces containing valuable chemical compounds, emerge. Some concrete plants utilize these byproducts as mineralogical additives in Turkey. The objective of the experimental study is to ascertain whether the incorporation of waste from the marble and brick industries, in powder form, into cement manufacturing as a mineralogical additive or substitute is a viable option.

The antiscale magnetic treatment (ASMT) claims to utilize magnetic field to combat scaling. However, its underlying mechanism, effectiveness, and reliability remain controversial. To address these contentious aspects, we analyze the influence of a magnetic field on the different stages of typical scale formation, using [Formula: see text] as a model scale.

Multiple Myeloma (MM) is a cytogenetically heterogeneous clonal plasma cell proliferative disease whose diagnosis is supported by analyses on histological slides of bone marrow aspirate. In summary, experts use a labor-intensive methodology to compute the ratio between plasma cells and non-plasma cells. Therefore, the key aspect of the methodology is identifying these cells, which relies on the experts' attention and experience.

Objective: To analyze acoustic measures of speech and vowel samples from individuals of different genders and to correlate these acoustic measures with vocal satisfaction. This study aims to provide additional data on acoustic measures, serving as references for clinicians while emphasizing the importance of moving beyond cisgender norms. Additionally, it addresses a gap in the Brazilian context by exploring correlations between acoustic measures and self-perceived vocal satisfaction across diverse gender groups.

Introduction: The escalating resistance of microorganisms to antimicrobials poses a significant public health threat. Strategies that use biomarkers to guide antimicrobial therapy-most notably Procalcitonin (PCT) and C-reactive protein (CRP)-show promise in safely reducing patient antibiotic exposure. While CRP is less studied, it offers advantages such as lower cost and broader availability compared with PCT.

Introduction: While cognitive behavioral therapy (CBT) remains a highly effective psychotherapy approach for managing Alcohol Use Disorder (AUD), its potential is hindered by workforce shortages and access barriers. In response to these challenges, Internet-Based Cognitive Behavioral Therapy (iCBT) has emerged as an innovative solution that integrates the core CBT structure with technology. In iCBT, educational materials, therapist communication and progress dashboards can be centralized in a digital format, and delivered in a self-guided, therapist-guided or blended approach.

Background: Preeclampsia is a major hypertensive disorder of pregnancy, which may lead to severe complications, particularly in the first two weeks of the postpartum period. During the postpartum period, blood pressure levels remain high, often increasing to levels higher than those experienced during pregnancy. Furosemide, a fast-acting diuretic, reduces the intravascular volume overload and may represent an alternative to accelerate the normalization of blood pressure levels.

Growing evidence of the benefits of home ventilatory support in patients with chronic respiratory failure along with technological advances in ventilators have enabled their use in overly complex situations, shaping a new scenario for physicians. This has further given rise to new challenges related to their incorporation into current medical practice. However, this evolution needs to be coupled with knowledge and skills of physicians who are willing to prescribe Home Mechanical Ventilation (HMV), in order to prevent them from making inappropriate choices or adjustments that may ultimately have ethical and legal implications.

The ovicidal effect of entomopathogenic fungi and the mechanisms involved are still debated. The hypothesis that the metabolic activity of germinating conidia can cause insect embryos to become unviable without physical penetration has been proposed. Here, we demonstrated that Metarhizium anisopliae and Metarhizium pingshaense, differently from Beauveria bassiana, reduced the percentage of nymphs hatching to less than 3%.

Tyramine, β-phenylethylamine, octopamine and other trace amines are endogenous substances recently recognized as important novel neurotransmitters in the brain. Trace amines act via multiple selective trace amine-associated receptors (TAARs) of the G protein-coupled receptor family. TAARs are expressed in various brain regions and modulate neurotransmission, neuronal excitability, adult neurogenesis, cognition, mood, locomotor activity and olfaction.

Dithranol is one of the most effective topical medications for treating plaque psoriasis. However, its clinical use is limited by irritative adverse reactions to the skin, such as oedema, erythema, and pruritus, caused by poorly understood mechanisms. Because TRPV1 activation mediates skin irritation caused by several drugs, we conducted blind and randomised experiments in male and female C57BL/6 mice to elucidate the role of TRPV1 in dithranol-induced irritation.

Background: Melanocytic neoplasms are rare in the oral cavity and represent a diagnostic challenge due to the overlap between benign and malignant lesions. However, their pathogenesis is not fully elucidated. The aim of this study was to evaluate the expression of the cell cycle-related proteins p16, CDK4, and PTEN in oral melanocytic nevi and melanomas.

Fear generalization, a lack of discrimination between safe and unsafe cues, is a hallmark of posttraumatic stress disorder. The phosphodiesterase 5 (PDE5) regulates the cyclic guanosine monophosphate (cGMP) pathway, which has been proposed to be involved in fear memory generalization. However, whether PDE5 activity underlies fear memory generalization remains unexplored.

The biotransformation of compounds is a critical point in understanding their toxic effects in both toxicology and ecotoxicology. The objective of this study was to evaluate whether there is a difference in the phytogenotoxic potential of the commercial fungicide Nativo® between non-biotransformed samples and samples biotransformed by swine liver enzymes. The fungicide Nativo is a mixture of Tebuconazole (TEB; 200 g L) and Trifloxystrobin (TRI; 100 g L).

In this work, we investigate the dynamics of a discrete-time prey-predator model considering a prey reproductive response as a function of the predation risk, with the prey population growth factor governed by two parameters. The system can evolve toward scenarios of mutual or only of predators extinction, or species coexistence. We analytically show all different types of equilibrium points depending on the ranges of growth parameters.
