Background/Objectives: Food insecurity (FI) is a well-defined factor in pediatric health outcomes and has been associated with lower diet quality. While poor diet quality has been linked to the rising prevalence of inflammatory bowel disease (IBD), little is known about the impact of FI on pediatric IBD. This pilot study explores the feasibility and potential impact of FI on dietary intake and clinical outcomes in children with newly diagnosed IBD. Methods: This pilot study included newly diagnosed IBD patients aged 5 to 18. FI screening was completed using the USDA 6-item and AAP 2-item screeners at diagnosis and 6 months. …

Extracellular matrix (ECM) components are key regulators in breast cancer progression, as ECM remodeling is essential for breast cancer cells to invade into surrounding tissue. This process is characterized by the alignment of fibrillar collagens, breakdown of basement membrane components, and increased interstitial collagen stiffness. In patients with obesity, pre-existing ECM changes, including excessive collagen deposition and heightened matrix stiffness, mimic alterations detected in breast cancer. Given that obesity is a predictor of poor prognosis and resistance to treatment in breast cancer, it is crucial to understand how ECM conditioned by obesity affects disease outcomes. In this review, we highlight …

Background: Older adults use nutritional complementary and alternative medicine (CAM) to reduce the risk of (or treat) non-communicable conditions and diet deficiencies. While prior research has explored the individual use of dietary supplements, vitamins, and minerals among older adults, few studies have examined factors influencing the combined use of these modalities, especially among Southern, older adults in the United States. Methods: Data were extracted from 419 participants from the University of Alabama at Birmingham Study of Aging II, a population-based longitudinal study of mobility among community-dwelling older adults. Self-reported data, including insurance and rural residence status, was collected. Comorbidity burden …

Fiber’s effect on our gut microbes has been studied extensively, while knowledge of the effect of protein is sparse. Colonic putrefaction of dietary protein is known to produce several potentially detrimental compounds. This randomized controlled trial (RCT) uses a pre- and post-study design to investigate the effect of consuming higher levels of dietary protein on the gut microbiota and the metabolites it produces. Here, we describe our virtual recruitment efforts and RCT protocol. Potential participants lived throughout the contiguous US. Several recruitment methods were employed, of which email reached the largest group of people (approximately 9,100) and generated a 0.3% …

In recent years, gut microbiota has emerged as a critical regulator of gastrointestinal health and disease, with its role in inflammatory bowel disease (IBD)—including Crohn’s disease and ulcerative colitis—being particularly significant. Among the many factors influencing the gut microbiota, dietary components such as fibers, fats, and polyphenols have received substantial attention. However, nitrogen-containing compounds, such as amino acids, nitrates, urea, and even nucleic acids, such as purines, remain underexplored despite their integral role in shaping microbial ecology, host metabolism, and immune responses. Some of these compounds are metabolized by gut bacteria into bioactive molecules such as short-chain fatty acids, ammonia, …

This paper reports the results of a mercury (Hg) and selenium (Se) metallomic study in the liver tissues of Psectrogaster amazonica and Raphiodon vulpinus from the Brazilian Amazon. Two-dimensional electrophoresis, graphite furnace atomic absorption spectrometry, and liquid chromatography-tandem mass spectrometry were performed. Hg and Se determinations allowed the calculation of Hg:Se and Se:Hg molar ratio and Se values for health benefits (Se HBVs). The Se:Hg values were >1 for both fish species, whereas the Se HBVs were >5 for P. amazonica and >10 for R. vulpinus, indicating that both possess Se reserves to control Hg toxicity. The metallomic data allowed …

INTRODUCTION: Oxygen toxicity has been defined as acute central nervous system (CNS), acute pulmonary, and chronic pulmonary oxygen toxicity. This study identifies acute and chronic CNS oxygen toxicity under 2.0 atmospheres absolute (ATA) pressure of oxygen. Methods: The authors' medical records from September 29, 1989 to January 20, 2023 and correspondence to the authors (9/1994 to 1/20.2023) from patients with signs and/or symptoms historically identified as acute CNS oxygen toxicity and those with neurological deterioration receiving hyperbaric oxygen for neurological conditions were reviewed. Acute cases were those occurring with ≤ 5 HBOTs and chronic cases > 5 HBOTs. Chronic cases were …

The gut microbiome plays a critical role in maintaining overall health and immune function. However, dysbiosis, an imbalance in microbiome composition, can have profound effects on various aspects of human health, including susceptibility to viral infections. Despite numerous studies investigating the influence of viral infections on gut microbiome, the impact of gut dysbiosis on viral infection and pathogenesis remains relatively understudied. The clinical variability observed in SARS-CoV-2 and seasonal influenza infections, and the presence of natural HIV suppressors, suggests that host-intrinsic factors, including the gut microbiome, may contribute to viral pathogenesis. The gut microbiome has been shown to influence the …

HIV-associated epidemic Kaposi sarcoma (EpKS) remains one of the most prevalent cancers in sub-Saharan Africa despite the widespread uptake of anti-retroviral therapy and HIV-1 suppression. In an effort to define potential therapeutic targets against KS tumors, we analyzed previously published KS bulk tumor transcriptomics to identify cell surface biomarkers. In addition to upregulated gene expression (>6-fold) in the EpKS tumor microenvironment, biomarkers were selected for correlation with KSHV latency-associated nuclear antigen (LANA) expression. The cell surface glycoprotein genes identified were KDR, FLT4, ADAM12, UNC5A, ZP2, and OX40, as well as the endothelial lineage determinants Prox-1 and CD34. Each protein …

Endogenously produced hydrogen sulfide (H2S) is critical for cardiovascular homeostasis. Therapeutic strategies aimed at increasing H2S levels have proven cardioprotective in models of acute myocardial infarction (MI) and heart failure (HF). The present study was undertaken to investigate the effects of a novel H2S prodrug, SG-1002, on stress induced hypertrophic signaling in murine HL-1 cardiac muscle cells. Treatment of HL-1 cells with SG-1002 under serum starvation without or with H2O2 increased the levels of H2S, H2S producing enzyme, and cystathionine β-synthase (CBS), as well as antioxidant protein levels, such as super oxide dismutase1 (SOD1) and catalase, and additionally decreased oxidative …

Background: Early childhood is the key life course period for development of social-emotional skills, providing the foundation for school readiness and resilience in later life. Age-appropriate yoga and mindfulness programs may contribute to the development of critical skills in children. Young children from minoritized communities that face structural racism and health disparities may benefit from programs that support social-emotional development and contribute to future academic success. Systematic reviews of yoga interventions for young children have indicated the potential for effectiveness in supporting social-emotional development, executive function, and physical activity. However, studies of yoga and mindfulness with non-White children are sparse …

Objective: To identify an age at which initiation of whole nut into the pediatric diet could be considered safe, by evaluating the age distribution of children undergoing bronchoscopy with removal of nut or seed material from the airway. Method: A retrospective chart review over a ten-year period identifying children age 0–18 that have undergone bronchoscopy with retrieval of airway foreign bodies. A statistical analysis of demographic data was carried out to identify age distribution of aspiration events. Results: Sixty-four cases of foreign body aspiration were identified, of which 43 (67%) were of organic origin, specifically nuts. A Fisher's exact test …
