Conditional cash transfer (CCT) programs have been implemented globally to alleviate poverty. Although tuberculosis (TB) is closely linked to poverty, the effects of CCT on TB outcomes among populations facing social and economic vulnerabilities remain uncertain. Here we estimated the associations between participation in the world's largest CCT program, the Brazilian Bolsa Família Program (BFP), and the reduction of TB incidence, mortality and case-fatality rates using the nationwide 100 Million Brazilian Cohort between 2004 and 2015.

Purpose: The aim of the present study was to establish a SYBR Green-based real-time PCR assay for detection of the Nc5 segment from the Neospora caninum genome.
Methods: The oligonucleotides sequences targeting the Nc5 gene previously reported and designed in-house were validated. Two Primer sets were evaluated and tested in four different combinations.
Purpose Of Review: This review aims to evaluate the impact of artificial intelligence (AI) on cancer health equity, specifically investigating whether AI is addressing or widening disparities in cancer outcomes.
Recent Findings: Recent studies demonstrate significant advancements in AI, such as deep learning for cancer diagnosis and predictive analytics for personalized treatment, showing potential for improved precision in care. However, concerns persist about the performance of AI tools across diverse populations due to biased training data.

Background: Optimised use of kidney function information might improve cardiac risk prediction in noncardiac surgery.
Methods: In 35,815 patients from the VISION cohort study and 9219 patients from the POISE-2 trial who were ≥45 yr old and underwent nonurgent inpatient noncardiac surgery, we examined (by age and sex) the association between continuous nonlinear preoperative estimated glomerular filtration rate (eGFR) and the composite of myocardial injury after noncardiac surgery, nonfatal cardiac arrest, or death owing to a cardiac cause within 30 days after surgery. We estimated contributions of predictive information, C-statistic, and net benefit from eGFR and other common patient and surgical characteristics to large multivariable models.

Molecular subtypes, such as defined by The Cancer Genome Atlas (TCGA), delineate a cancer's underlying biology, bringing hope to inform a patient's prognosis and treatment plan. However, most approaches used in the discovery of subtypes are not suitable for assigning subtype labels to new cancer specimens from other studies or clinical trials. Here, we address this barrier by applying five different machine learning approaches to multi-omic data from 8,791 TCGA tumor samples comprising 106 subtypes from 26 different cancer cohorts to build models based upon small numbers of features that can classify new samples into previously defined TCGA molecular subtypes-a step toward molecular subtype application in the clinic.

Introduction: People Living with Human Immunodeficiency Virus (PLHIV) appear to be at a higher risk of developing sarcopenia. Various factors seem to influence the risk of sarcopenia, and its prevalence may differ depending on the screening tool used. This study aimed to (i) Screen the risk of sarcopenia in PLHIV using the SARC-F and SARCCalf and identify associated factors; (ii) Analyze the agreement between the instruments in PLHIV.

Silicon (Si) and arbuscular mycorrhizal fungi (AMF) increase plant resistance to various environmental stresses, including heavy metal (and metalloid) toxicity. Although Si and AMF each independently enhance plant tolerance, the nature of their interactions and their combined impacts on nutrient uptake, especially in the context of toxic elements such as arsenic (As), remains to be elucidated. This study investigated AMF-mediated regulation of plant nutrient uptake under As stress using rice, a model Si-accumulating plant.

High-energy nuclear collisions create a quark-gluon plasma, whose initial condition and subsequent expansion vary from event to event, impacting the distribution of the eventwise average transverse momentum [P([p_{T}])]. Disentangling the contributions from fluctuations in the nuclear overlap size (geometrical component) and other sources at a fixed size (intrinsic component) remains a challenge. This problem is addressed by measuring the mean, variance, and skewness of P([p_{T}]) in ^{208}Pb+^{208}Pb and ^{129}Xe+^{129}Xe collisions at sqrt[s_{NN}]=5.

Background: The offspring of parents with bipolar disorder (BD) and with attention deficit hyperactivity disorder (ADHD) have a higher risk of having the same condition. Both disorders also share psychopathological symptoms; however, little is known about their genetic overlap. To examine whether the offspring of parents with BD have a greater chance of being affected by ADHD, we conducted a systematic review.

Atopic dermatitis (AD) is a disease that significantly impacts the quality of life of patients. Although there are multiple evidence-based guidelines, they are usually aimed at providing recommendations to AD specialists rather than primary care physicians (PCPs). The aim of this study was to construct a consensus document for PCPs, with the aim of presenting evidence-based recommendations that allow general practitioners, family physicians, pediatricians, internists and emergency physicians to provide appropriate care to AD patients, facilitating their diagnosis, management, and avoiding delays that can deteriorate patients' f quality of life.

To assess and compare two techniques of low-level laser application-transgingival (TLLLT) and intrasulcular (ILLLT)-used in photobiomodulation as an adjunct to basic periodontal therapy (BPT) in patients with periodontitis. A randomized, split-mouth, double-blind clinical trial was conducted, selecting three diseased periodontal sites from different quadrants in each patient. These sites were assigned to one of three treatment groups: SRP (control), SRP + TLLLT (test 1), and SRP + ILLLT (test 2).

This study aims to use superparamagnetic iron oxide nanoparticles (SPIONs), specifically magnetite (FeO), to deliver deflazacort (DFZ) and ibuprofen (IBU) to Duchenne muscular dystrophy-affected (DMD) mouse muscles using an external magnetic field. The SPIONs are synthesized by the co-precipitation method, and their surfaces are functionalized with L-cysteine to anchor the drugs, considering that the cysteine on the surface of the SPIONs in the solid state dimerizes to form the cystine molecule, creating the FeO-(Cys)-DFZ and FeO-(Cys)-IBU systems for tests. The FeO nanoparticles (NPs) were characterized by Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, powder X-ray diffraction (PXRD), transmission electron microscopy (TEM), dynamic light scattering (DLS), and magnetic measurements.

Background: Alzheimer's disease (AD) is the leading cause of dementia in elderly humans worldwide. More than 40 million people currently suffer from AD, and this prevalence tends to increase considerably in the coming decades due to increased longevity. The unfolded protein response (UPR) is an adaptive signaling mechanism that aims to maintain cell viability under misfolded protein accumulation and endoplasmic reticulum stress.

Background: Alzheimer's disease (AD) is a progressive neurodegenerative disease characterized by synapse and memory failure, and severe cognitive impairment. Physical exercise stimulates neuroprotective pathways, has pro-cognitive actions, and has been reported to alleviate memory impairment in AD. Irisin, an exercise-induced hormone, is secreted following proteolytic cleavage of fibronectin type-III-domain-containing 5 (FNDC5).
