Background: Uranium exposure remains an important environmental legacy and physiological health concern, with hundreds of abandoned uranium mines located in the Southwestern United States largely impacting underserved indigenous communities. The negative effects of heavy metals on barrier permeability and inhibition of intestinal epithelial healing have been described; however, transcriptomic changes within the intestinal epithelial cells and impacts on lineage differentiation are largely unknown.
Objectives: Herein, we sought to determine the molecular and cellular changes that occur in the colon in response to uranium bearing dust (UBD) exposure.
Prcis: This meta-analysis examines the comparative efficacy of phacoemulsification with and without Kahook Dual Blade Goniotomy in individuals with glaucoma and cataract, aiming to elucidate optimal surgical approaches for coexisting conditions.
Purpose: The purpose of this current study is to compare the effect of combining Kahook Dual Blade (KDB) goniotomy with phacoemulsification versus phacoemulsification alone on intraocular pressure (IOP) and medication reduction in patients with glaucoma and cataract.
Methods: We conducted a systematic review and meta-analysis utilizing computer databases, including Embase (OVID), MEDLINE (OVID and PubMed), CINHAL (EBSCO), and the Cochrane Library (Wiley).
Objective: Nasal Intermittent Positive Pressure Ventilation (NIPPV) is an effective therapy for infants in respiratory distress. We here report the safety of a novel, low-cost, non-electric bubble NIPPV device in comparison with bubble NCPAP.
Study Design: At Paramitha Children's Hospital (Hyderabad, India), preterm (n = 60) neonates with moderate respiratory distress were pragmatically allocated to bubble NCPAP (5-8 cm HO) or bubble NIPPV (P 8-12 cm HO/P 5-8 cm HO) based on staff and equipment availability.
Introduction: More frequent and severe lupus nephritis (LN) has been reported in men compared to women, but data are limited and inconsistent. We conducted a meta-analysis of the literature to compare the histopathologic findings and outcomes between men and women with biopsy-proven LN.
Methods: A systematic search of MEDLINE, Embase, Cochrane, and Web of Science databases was conducted through February 2021.
Background: Acute Bilirubin Encephalopathy (ABE) is common in Nigeria. Parents' inability to recognize jaundice and delays in seeking care are significant barriers to its prevention.
Methods: We compared associations of (1) interactive antenatal maternal jaundice instruction with postnatal reinforcement, (2) standard postnatal instruction, and (3) no maternal instruction with the incidence of ABE among 647 jaundice admissions stratified for risk factors identified in initial descriptive analysis.
We studied the co-occurrence of microplastics (MPs) and metals in field sites and further investigated their interfacial interaction in controlled laboratory conditions. First, we detected MPs in freshwater co-occurring with metals in rural and urban areas in New Mexico. Automated particle counting and fluorescence microscopy indicated that particles in field samples ranged from 7 to 149 particles/L.

Methods: We conducted a multicenter, randomized study that included patients undergoing spinal fusion for single thoracic curves between 45° and 65°, the most common form of operatively treated AIS. Of the 211 patients randomized, 108 were assigned to a high-density screw pattern and 103, to a low-density screw pattern.
Chronic exposure to environmental toxins and heavy metals has been associated with intestinal inflammation, increased susceptibility to pathogen-induced diseases, and higher incidences of colorectal cancer, all of which have been steadily increasing in prevalence for the past 40 years. The negative effects of heavy metals on barrier permeability and inhibition of intestinal epithelial healing have been described; however, transcriptomic changes within the intestinal epithelial cells and impacts on lineage differentiation are largely unknown. Uranium exposure remains an important environmental legacy and physiological health concern, with hundreds of abandoned uranium mines located in the Southwestern United States largely impacting underserved indigenous communities.

This pilot study describes the development, acceptability and feasibility of a novel toolkit approach focusing on a systematic 4-step process for ensuring medication appropriateness. A preliminary qualitative assessment of the toolkit's acceptability and feasibility was carried out using a convenience sample of 39 residents aged 62-97 years in two senior living facilities convened in focus groups.
View Article and Find Full Text PDFLower respiratory tract infections (LRTIs) are the leading cause of death in young children globally. Most of the global burden of mortality from LRTIs occurs in low-resource settings (LRSs), where obtaining and maintaining respiratory support devices such as commercial bubble continuous positive airway pressure (bCPAP) can be prohibitive. Low-cost bCPAP devices exist, such as the homemade WHO-style bCPAP design, but the safety of this design has been called into question.

Furthermore, environmental factors may modify the plastic chemistry, further altering the toxic potency. Ultraviolet (UV) light is one such unavoidable factor for airborne microplastic particulates and a known modifier of polystyrene surface chemistry.

Gadolinium is the active ingredient of these contrast agents, a non-physiologic lanthanide metal. The mechanisms of MRI contrast agent-induced diseases are unknown.

However, the optimal duration and frequency of KC to maximize health outcomes is unknown. Given parents' time stressors, identifying optimal KC time is critical.

We show that a potent SARM1 inhibitor undergoes base exchange with the nicotinamide moiety of nicotinamide adenine dinucleotide (NAD) to produce the bona fide inhibitor 1AD. We report structures of SARM1 in complex with 1AD, NAD mimetics and the allosteric activator nicotinamide mononucleotide (NMN).

Laboratory batch experiments show that the adsorption and precipitation of U(VI) in the presence of NOM occur at pH 2 and pH 4, while the aqueous complexation of U by dissolved organic matter is favored at pH 7, preventing its precipitation. Spectroscopic analyses indicate that U(VI) is mainly adsorbed to the particulate organic matter at pH 4.

The samples are characterized by average grain sizes of 90 nm, 93 nm and 179 nm (hereinafter referred to as samples Gr90, Gr93, and Gr179, respectively). The experimentally determined sound velocities and elastic properties of Gr179 sample are comparable with previous measurements, but slightly higher than those of Gr90 and Gr93 under ambient conditions.
