Spatial molecular profiling has provided biomedical researchers valuable opportunities to better understand the relationship between cellular localization and tissue function. Effectively modeling multimodal spatial omics data is crucial for understanding tissue complexity and underlying biology. Furthermore, improvements in spatial resolution have led to the advent of technologies that can generate spatial molecular data with subcellular resolution, requiring the development of computationally efficient methods that can handle the resulting large-scale datasets.

Background: Globally, over one-third of pulmonary tuberculosis (TB) disease diagnoses are made based on clinical criteria after a negative bacteriological test result. There is limited information on the factors that determine clinicians' decisions to initiate TB treatment when initial bacteriological test results are negative.

Methods And Findings: We performed a systematic review and individual patient data meta-analysis using studies conducted between January 2010 and December 2022 (PROSPERO: CRD42022287613).

Population-level estimates in timeframes for reaching cervical cancer (CC) elimination (ie, <4 cases per 100,000 women) in the United States may mask potential disparities in achieving elimination among sub-populations. We used three independent Cancer Intervention and Surveillance Modeling Network (CISNET) models to estimate differences in the time to CC elimination across seven strata of correlated screening and human papillomavirus vaccination uptake, based on national survey data. Compared to the average population, elimination was achieved ≥22 years earlier for the high-uptake strata and ≥27 years later for the most extreme low-uptake strata.

: The development of a five-in-one vaccine microneedle patch (five-in-one MN patch) aims to address challenges in administering vaccines against Diphtheria (DT), Tetanus (TT), Pertussis (wP), Hepatitis B (HBsAg), and type b (Hib). Combining multiple vaccines into a single patch offers a novel solution to improve vaccine accessibility, stability, and delivery efficiency, particularly in resource-limited settings. : The five-in-one MN patch consists of four distinct microneedle arrays: DT and TT vaccines are coated together on one array, while wP, HepB, and Hib vaccines are coated separately on individual arrays.

Exposure to saturated fatty acids (SFAs), such as palmitic acid, can lead to cellular metabolic dysfunction known as lipotoxicity. Although canonical adaptive metabolic processes like lipid storage or desaturation are known cellular responses to saturated fat exposure, the link between SFA metabolism and organellar biology remains an area of active inquiry. We performed a genome-wide CRISPR knockout screen in human epithelial cells to identify modulators of SFA toxicity.

Single cell ATAC-seq (scATAC-seq) experimental designs have become increasingly complex, with multiple factors that might affect chromatin accessibility, including genotype, cell type, tissue of origin, sample location, batch, etc., whose compound effects are difficult to test by existing methods. In addition, current scATAC-seq data present statistical difficulties due to their sparsity and variations in individual sequence capture.

Unlabelled: Many middle-aged to older adults do not engage in regular exercise at all, despite its importance for healthy aging. Extensive research grounded in behavioral and social science theories has identified numerous determinants of exercise. However, few studies used an exposure-wide approach, a data-driven exploratory method particularly useful for identifying novel determinants.

Background: Lipid species are emerging as biomarkers for cardiometabolic risk in both adults and children. The genetic regulation of lipid species and their impact on cardiometabolic risk during early life remain unexplored.

Methods: Using mass spectrometry-based lipidomics, we measured 227 plasma lipid species in 1149 children and adolescents (44.

New approach methods (NAMs) are required to predict human toxicity effectively, particularly due to limitations in conducting in vivo studies. While NAMs have been established for various industries, such as cosmetics, pesticides, and drugs, their applications in natural products (NPs) are lacking. NPs' complexity (multiple ingredients and structural differences from synthetic compounds) complicates NAM development.

The functional specialization of CD4 T lymphocytes into various subtypes, including T1 and T cells, is crucial for effective immune responses. T cells facilitate B cell differentiation within germinal centers, while T1 cells are vital for cell-mediated immunity against intracellular pathogens. Integrin α4, a cell surface adhesion molecule, plays significant roles in cell migration and co-stimulatory signaling.

This study investigates the link between life course social mobility and cognitive function among middle-aged and older adults in India, specifically emphasizing whether upward and downward mobility exerts symmetric associations and potential gender heterogeneity within these associations. Leveraging data from the Longitudinal Aging Study in India 2017-2018, encompassing 64,710 individuals aged 45 years or above, we classified social mobility as 'consistently high,' 'upward mobility,' 'downward mobility,' and 'consistently low,' based on socioeconomic position during childhood and late adulthood. Multivariable regression and gender-interaction analyses were employed to assess associations.

Despite increasing utilization of CAR T-cell therapy, data are lacking regarding long term follow up and risk of infectious complications after the early period following CAR T-cell infusion. In this study, we sought to compare epidemiology and risk factors for early (≤ 3 months) and late (3 months to 1 year) infections. Data were retrospectively collected at six time points: pre-CAR T, day of infusion, and at 3, 6, 9, and 12 months post CAR-T infusion for all consecutive adult patients treated at our institution.

Background: Pulmonary vein isolation (PVI) alone is less effective in patients with persistent atrial fibrillation (AF) compared with those with paroxysmal AF. We investigate whether additional linear ablation from the superior vena cava to the right atrial septum and cavotricuspid isthmus ablation improves the rhythm outcome of patients with persistent AF undergoing cryoballoon PVI (Cryo-PVI).

Methods: In this investigator-initiated, multicenter, randomized clinical trial, 289 patients with persistent AF refractory to antiarrhythmic drug therapy were randomized 1:1 to either Cryo-PVI with additional right atrium (RA) linear ablation or Cryo-PVI alone.

Developmental science has a long history of studying skills that children need to thrive. However, there has been a primary focus on academic skills, with little attention to the breadth and diversity of other skills that young children need to thrive. Furthermore, little is known about the extent to which community experts involved in early childhood care and education (ECCE) value different early developmental skills.

Classic regulatory T (T) cells expressing CD4 and the hallmark transcription factor FOXP3 are integral to the prevention of multi-system autoimmunity. However, immune-mediated arthritis is often associated with increased numbers of T cells in the inflamed joints. To understand these seemingly conflicting observations, which we collectively describe as 'the T paradox', we provide an overview of T cell biology with a focus on T cell heterogeneity, function and dysfunction in arthritis.

Though child anthropometric failure (CAF) is a persistent problem in India, previous studies have often neglected state-level variance and aggregated moderate and severe CAF categories. This study addresses this gap by examining moderate and severe malnutrition across India's states and union territories (UTs) from 1993 to 2021. Data of children under 2 years old from five waves of National Family Health Surveys, a representative cross-sectional survey of Indian households, were analysed.

Article Synopsis
  • Memory-phenotype (MP) CD4 T lymphocytes develop from naïve T cells and can differentiate into various T cell subsets to manage inflammation, especially in low-immune settings.
  • The study highlights that MP lymphocytes are not only made up of T helper 1 (T1) and T helper 17 (T17) cells but also contain a "undifferentiated" subpopulation that has the potential to develop into these functional subsets.
  • The undifferentiated MP lymphocytes possess the ability to proliferate rapidly and can differentiate into T1, T17, and regulatory T cells, which contributes to inflammation, although their response is regulated by existing T cells.
