Background: Pulmonary tuberculosis (PTB) exacerbation can lead to respiratory failure, multi-organ failure, and symptoms related to central nervous system diseases. The purpose of this study is to screen biomarkers and metabolic pathways that can predict the progression of PTB, and to verify the role of the metabolic enzyme xanthine oxidase (XO) in the progression of PTB.
Methods: To explore the biomarkers and mechanisms underlying the progression of PTB, plasma metabolomics sequencing was conducted on patients with severe PTB, non-severe PTB, and healthy individuals.

Objectives: The objective of this investigation was to compile existing observational research and quantify the potential association between ultra-processed foods (UPFs) and the risk of insomnia using meta-analysis.
Setting: We conducted a systematic search of the PubMed/MEDLINE, Scopus, and ISI Web of Science databases with no restrictions until 29 June 2024. Odds ratios (OR) and 95% confidence intervals (CI) were aggregated using a random-effects model, while the Newcastle-Ottawa Scale and Egger's regression asymmetry test assessed study quality and publication bias, respectively.

Background/objectives: Food insecurity (FI) is defined as the lack of consistent access to enough food for an active and healthy life. FI affects over 30 million Americans and is associated with poor clinical outcomes and impaired quality of life and drives significant health inequities. Despite the rising prevalence of FI and the federal focus on improving access to healthy food, there is a paucity of research on FI in patients with inflammatory bowel disease (IBD).

: The influence of comorbidity on long-term hospitalization and mortality after COVID-19 in adults (40-59 years) and older adults (≥60 years) is yet to be explored. : This is a Danish population-based cohort study of patients with a first-time positive PCR test for COVID-19 from 1 March 2020, to 28 February 2022 (N = 1,034,103). Exposed cohorts were patients with 1) a Charlson Comorbidity Index (CCI) score of 1-2 and 2) a CCI score ≥3, who were compared to patients without comorbidity (CCI of zero) within the groups of adults (67.

Sports cardiology is an evolving field in cardiology, with several topics remaining controversial. Beyond the several well-known benefits of regular exercise practice, the occurrence of adverse clinical events during sports in apparently healthy individuals, especially sudden cardiac death, and the described long-term adverse cardiac adaptations associated to high volume of exercise, remain challenging. The early identification of athletes with increased risk is critical, but the most appropriate preparticipation screening protocols are also debatable and a more personalized evaluation, considering individual and sports-related characteristics, will potentially optimize this evaluation.

Background: Protein tyrosine phosphatase 1B (PTP1B) is a protein tyrosine phosphatase and modulates platelet-derived growth factor (PDGF)/platelet-derived growth factor receptor (PDGFR) signaling in vascular smooth muscle cells (VSMCs) via endocytosis. However, the related molecular pathways that participated in the interaction of endo-lysosome and the trafficking of PDGFR are largely unknown. This study aims to determine the subcellular regulating mechanism of PTP1B to the endo-lysosome degradation of PDGFR in atherosclerotic carotid plaques, thereby offering a potential therapeutic target for the stabilization of carotid plaques.

Acute respiratory distress syndrome (ARDS) can be associated with a wide multiplicity of causes, including diffuse alveolar haemorrhage (DAH). Vasculitis associated with anti-neutrophil cytoplasmic antibody (ANCA), particularly granulomatosis with polyangiitis (GPA), is one of the most common causes of DAH, primarily affecting small and medium-sized vessels in the lungs and kidneys. Diagnosing GPA can be challenging, and it should be considered a potential cause of DAH, even in the absence of other organ involvement.

Background and aims: nutritional screening tools assess factors like weight loss, BMI, food intake, and disease severity to determine a patient's nutritional risk and needed care. Plasma transthyretin is a practical measurement used to assess nutritional evolution due to its rapid response to food intake. This study examines the relationship between nutritional scores, transthyretin protein levels, and the possibility of death.

Aim: To estimate the prevalence of nocturia in middle-aged and elderly men and evaluate its associated factors and changes over time.
Methods: Data of middle-aged and older men aged ≥40 years from the 2007-2008 and 2017-2020 cycles of the National Health and Nutrition Examination Survey were retrospectively analyzed. The prevalence of nocturia was estimated using participant questionnaires on nocturia, lifestyle-related factors, and health factors, and its decadal changes were examined using multivariate logistic regression analysis to determine related factors associated with the prevalence of nocturia.

Ophthalmic neurodegenerative diseases related to diabetes, such as glaucoma and retinopathy, are among the major causes of blindness in the world. Citicoline (CIT) in the form of eye drops is currently used for the treatment/prevention of these diseases, which affect the posterior segment of the eye. To ensure the drug penetration into the back of the eye, frequent instillations of highly concentrated drug solutions are required with potential side effects.

Introduction: Over the past decade, there has been an improvement in access to gender-affirming surgical care for the transgender population. Even with improvements, this population continues with a high level of inequity among access to specialized surgical care. While multiple studies have previously focused on trends among top and bottom surgery, this study provides trends specifically among facial gender affirmation surgery (FGAS) within the United States.

Importance: Beginning in 2005, the US implemented routine immunization of adolescents with a quadrivalent conjugate vaccine (MenACWY) for the prevention of invasive meningococcal disease (IMD).
Objectives: To assess whether MenACWY immunization was associated with a reduced IMD burden among the US adolescent population and how the downward trajectory of IMD that began in the mid-1990s might have evolved in the absence of vaccination efforts.
Design, Setting, And Participants: In this decision analytical study, a bayesian hierarchical Poisson regression model was developed to investigate the potential trajectory of IMD among US adolescents and young adults without vaccination and evaluate the direct association of vaccination with IMD burden.

Background: Reversible short-term fluctuations in the frailty index (FI) are often thought of as representing only noise or error. Here, we assess (i) the size and source of short-term FI fluctuations, (ii) variation across sociodemographic characteristics, (iii) association with chronic diseases, (iv) correlation with age, frailty level, frailty change, and mortality, and (v) whether fluctuations reflect discrete health transitions.
Methods: Nationwide, biweekly longitudinal data from 426 community-dwelling older adults (70+) were collected in the FRequent health Assessment In Later life (FRAIL70+) study using a measurement burst design (5 122 repeated observations, median of 13 repeated observations per person).

Background And Objective: Modelling patient-specific aortic biomechanics with advanced computational techniques, such as Fluid-Structure Interaction (FSI), can be crucial to provide effective decision-making indices to enhance current clinical practices. To effectively simulate Ascending Thoracic Aortic Aneurysms (ATAA), the stress-free configuration must be defined. The Zero Pressure Geometry (ZPG) and the Prestress Tensor (PT) are two of the main approaches to tackle this issue.
