While alcohol use is culturally embedded in many Nepalese communities, evidence regarding the prevalence of problematic drinking and its associated factors remains scarce among youths. This study aims to assess the prevalence of alcohol consumption and problematic drinking and their associated factors among management undergraduate students of Bhaktapur, Nepal.

Anatomically-detailed segmented representative adult and pediatric nasal models for assessing regional drug delivery and bioequivalence with suspension nasal sprays.

In vitro nasal models can potentially facilitate development and approval of nasal drug products. This study aims to evaluate the potential for using regional deposition measurements from in vitro nasal models to evaluate nasal spray performance across several products. To accomplish this, the posterior regions of six anatomically realistic nasal airway models of adult and pediatric subjects, representing Low (L), Mean (M) and High (H) posterior drug deposition (PD) for each of the two age groups, were segmented with high anatomical precision into five regions of interest.

Radiological manifestations of nail-patella syndrome in a 56-year-old female: A case report.

Nail-patella syndrome (NPS) is a rare autosomal dominant pleiotropic disorder characterized by dysplasia of the nails, patellar aplasia or hypoplasia, iliac horns and dysplasia of the elbows. We present a case of a 56-year-old female presenting with bilateral knee pain, where initial radiographic findings of hypoplastic patellae prompted further investigation, revealing characteristic skeletal anomalies consistent with NPS. This case underscores the importance of recognizing radiological clues and conducting thorough clinical evaluation to diagnose rare genetic conditions such as NPS.

Our current understanding of the biological impact of endometrial cancer mtDNA genome mutations and their potential use as a biomarker.

Endometrial cancer (EC) is a devastating and common disease affecting women's health. The NCI Surveillance, Epidemiology, and End Results Program predicted that there would be >66,000 new cases in the United States and >13,000 deaths from EC in 2023, and EC is the sixth most common cancer among women worldwide. Regulation of mitochondrial metabolism plays a role in tumorigenesis.

HIV-1 subtype A1, D, and recombinant proviral genome landscapes during long-term suppressive therapy.

The primary obstacle to curing HIV-1 is a reservoir of CD4+ cells that contain stably integrated provirus. Previous studies characterizing the proviral landscape, which have been predominantly conducted in males in the United States and Europe living with HIV-1 subtype B, have revealed that most proviruses that persist during antiretroviral therapy (ART) are defective. In contrast, less is known about proviral landscapes in females with non-B subtypes, which represents the largest group of individuals living with HIV-1.

Effects of a dietary intervention on cardiometabolic risk and food consumption in a workplace.

We aimed to determine the effect of cafeteria intervention on cardio-metabolic risk factors diet in a worksite setting (Dhulikhel Hospital) in Nepal.

Methods: In this one-arm pre-post intervention study, we recruited 277 non-pregnant hospital employees aged 18-60 with prediabetes or pre-hypertension.

The quest to deliver high-dose rifampicin: can the inhaled approach help?

Introduction: Tuberculosis (TB) is a global health problem that poses a challenge to global treatment programs. Rifampicin is a potent and highly effective drug for TB treatment; however, higher oral doses than the standard dose (10 mg/kg/day) rifampicin may offer better efficacy in TB treatment.

Areas Covered: High oral dose rifampicin is not implemented in anti-TB regimens yet and requires about a 3-fold increase in dose for increased efficacy.

Despite misinformation, low trust, and conflict in Somalia, high demand for vaccines and a negative endorsement effect of non-state authorities.

Expanding vaccination coverage in conflict regions is crucial to the prevention of further mutations and outbreaks of COVID-19, as well as of future pandemics, worldwide. However, scholars' suppositions that low levels of trust and control over the flow of misinformation in these regions may necessitate tailored solutions-in particular, that health advice come from trusted non-state authorities-remain largely untested. To better understand the levels and drivers of COVID-19 vaccine receptivity in conflict regions, we partnered with the United Nations and the Somali Ministry of Justice to field a three-wave panel survey ([Formula: see text] = 1672; [Formula: see text] = 880; [Formula: see text] = 908) and vaccine endorsement experiment in South Central Somalia.

Elicitor-induced plant immunity relies on amino acids accumulation to delay the onset of bacterial virulence.

Plant immunity relies on the perception of microbe-associated molecular patterns (MAMPs) from invading microbes to induce defense responses that suppress attempted infections. It has been proposed that MAMP-triggered immunity (MTI) suppresses bacterial infections by suppressing the onset of bacterial virulence. However, the mechanisms by which plants exert this action are poorly understood.

Economic and Diagnostic Biomarker Tests of Neonatal Sepsis: A Prospective Study from a Tertiary Care Hospital in a Low-Income Country.

There are several sophisticated biomarkers; however, they are still insufficient in precision. In this perspective, our study aims to search for a pragmatic diagnostic biomarker in the age category.

In vitro Dissolution Testing of Rifampicin Powder Formulations For Prediction of Plasma Concentration-Time Profiles After Inhaled Delivery.

Purpose: The purpose of this study was to evaluate the in vitro lung dissolution of amorphous and crystalline powder formulations of rifampicin in polyethylene oxide (PEO) and 1,2-dipalmitoyl-sn-glycero-3-phosphatidylcholine (DPPC), and to predict the in vivo plasma concentration-time profiles using the in vitro data.

Methods: The in vitro dissolution and permeation profiles of respirable rifampicin particles were studied using a custom-made dissolution apparatus. Data from the in vitro dissolution test were used to estimate the parameters to be used as the input for the simulation of in vivo plasma concentration-time profiles using STELLA® software.

A review of formulations and preclinical studies of inhaled rifampicin for its clinical translation.

Inhaled drug delivery is a promising approach to achieving high lung drug concentrations to facilitate efficient treatment of tuberculosis (TB) and to reduce the overall duration of treatment. Rifampicin is a good candidate for delivery via the pulmonary route. There have been no clinical studies yet at relevant inhaled doses despite the numerous studies investigating its formulation and preclinical properties for pulmonary delivery.

SARS CoV-2 mRNA vaccination exposes latent HIV to Nef-specific CD8 T-cells.

Efforts to cure HIV have focused on reactivating latent proviruses to enable elimination by CD8 cytotoxic T-cells. Clinical studies of latency reversing agents (LRA) in antiretroviral therapy (ART)-treated individuals have shown increases in HIV transcription, but without reductions in virologic measures, or evidence that HIV-specific CD8 T-cells were productively engaged. Here, we show that the SARS-CoV-2 mRNA vaccine BNT162b2 activates the RIG-I/TLR - TNF - NFκb axis, resulting in transcription of HIV proviruses with minimal perturbations of T-cell activation and host transcription.

Single cell spatial analysis reveals the topology of immunomodulatory purinergic signaling in glioblastoma.

How the glioma immune microenvironment fosters tumorigenesis remains incompletely defined. Here, we use single-cell RNA-sequencing and multiplexed tissue-imaging to characterize the composition, spatial organization, and clinical significance of extracellular purinergic signaling in glioma. We show that microglia are the predominant source of CD39, while tumor cells principally express CD73.

Structural variants shape driver combinations and outcomes in pediatric high-grade glioma.

We analyzed the contributions of structural variants (SVs) to gliomagenesis across 179 pediatric high-grade gliomas (pHGGs). The most recurrent SVs targeted MYC isoforms and receptor tyrosine kinases (RTKs), including an SV amplifying a MYC enhancer in 12% of diffuse midline gliomas (DMG), indicating an underappreciated role for MYC in pHGG. SV signature analysis revealed that tumors with simple signatures were TP53 wild type (TP53) but showed alterations in TP53 pathway members PPM1D and MDM4.
