Need for and update on clinical trials for uncomplicated type B aortic dissection.

The mainstay of management for uncomplicated type B aortic dissection is currently optimal medical therapy, targeting blood pressure and heart rate, along with serial imaging. There is a paucity of data that informs whether early intervention with thoracic endografting in this group of patients will promote aortic remodeling and better long-term outcomes. Investigations to date, including the Investigation of Stent Grafts in Aortic Dissection (INSTEAD), INSTEAD-XL, and Acute Dissection: Stent Graft or Best Medical Therapy (ADSORB) studies, have compared thoracic endovascular aortic repair (TEVAR) with optimal medical therapy in patients with uncomplicated type B aortic dissection but have not shown a benefit for TEVAR conclusively.

Social Norms Regarding Alcohol Use, Perceptions of Alcohol Advertisement and Intent to Drink Alcohol among Youth in Uganda.

The objective of this paper is to address the scarcity of research on alcohol marketing exposure and underage drinking in sub-Saharan Africa. This study examines perceptions of alcohol advertisements and perceived peer, adult, and parental attitudes regarding alcohol use and intentions to drink among vulnerable youth. The Kampala Youth Survey is a cross-sectional study conducted in 2014 with service-seeking youth (ages 12-18 years) living in the slums of Kampala (n=1,134) who were participating in Uganda Youth Development Link drop-in centers.

Promoting braveness in children: A pilot study on the effects of a brief, intensive CBT-based anxiety prevention programme conducted in the South African context.

Background: Children within historically disadvantaged non-Western South African communities are considered as particularly vulnerable to the development of anxiety problems. Although the need for accessible mental health interventions is evident, this need has remained unmet in a country with extreme socio-economic disparities and a lack of mental health resources. Cognitive behavioural therapy-based (CBT-based) interventions that employ brief and intensive delivery methods may overcome existing barriers to access to mental health services faced by many South African children and may ameliorate the burden placed on under-resourced mental health care services.

LGBTQ+ youth policy and mental health: Indirect effects through school experiences.

The link between state policies and LGBTQ+ youth mental health is well-established, yet less well-understood are the mechanisms that drive these associations. We used a sample from the LGBTQ+ National Teen Survey (n = 8368) collected in 2022 to examine whether and to what degree LGBTQ+ inclusive school strategies, student perceptions of school safety, and experiences with bias-based bullying and peer victimization explain the association between state LGBTQ+ youth-focused policies and LGBTQ+ youth mental health symptomology. We observed significant indirect effects between policy and LGBTQ+ youth mental health through all four constructs, suggesting that each of these more proximal school experiences was independently implicated in this association.

Ghana's water safety journey: A review of efforts toward a risked-based water quality management.

In 2015, Ghana launched the National Drinking Water Quality Management Framework (NDWQMF) to promote a risk-based approach to water quality through water safety plans (WSPs). This study uses a narrative review to synthesize WSP implementation progress in Ghana, identify gaps in practice, and provide recommendations for enhanced effectiveness and scale-up. Findings show limited uptake: only three of 88 urban water supply systems have adopted WSPs, while in the rural sector, the Community Water and Sanitation Agency has implemented WSPs in 177 of 1,022 small-town systems, and the safe water network in 46 systems.

Discriminative stimulus properties of α-ethyltryptamine (α-ET) in rats: α-ET-like effects of MDMA, MDA and aryl-monomethoxy substituted derivatives of α-ET.

Rationale α-ET (α-ethyltryptamine), a homolog of the classical hallucinogen α-methyltryptamine, was once prescribed clinically as an antidepressant. Classical psychedelic drugs are currently of interest as potential pharmacotherapy for psychiatric disorders. Objectives Drug discrimination was used to (a) determine if α-ET-like stimulus effects could be engendered by the prototypical phenylalkylamines MDMA ("Ecstasy") or MDA ("Love Drug") and (b) evaluate the α-ET-like stimulus effects of four synthesized aryl-substituted monomethoxy analogs of α-ET (4-OMe-, 5-OMe-, 6-OMe- and 7-OMe-α-ET).

Risk perception and mpox vaccine acceptability among people living with HIV in northern Nigeria.

Background: There is a dearth of information regarding mpox risk perception and vaccine acceptance among people living with human immunodeficiency virus (HIV), especially in countries with a dual burden of HIV and mpox, such as Nigeria.

Methods: We used an explanatory mixed methods design and structured questionnaires administered to a clinic-based sample of people living with HIV (n=430), followed by in-depth interviews with a purposive subsample (n=20). Data were analysed using binary logistic regression and the framework approach.

Macular patterns of neuronal and visual field loss in recovered optic neuritis identified by machine learning.

We used machine learning to investigate the residual visual field (VF) deficits and macula retinal ganglion cell (RGC) thickness loss patterns in recovered optic neuritis (ON). We applied archetypal analysis (AA) to 377 same-day pairings of 10-2 VF and optical coherence tomography (OCT) macula images from 93 ON eyes and 70 normal fellow eyes ≥ 90 days after acute ON. We correlated archetype (AT) weights (total weight = 100%) of VFs and total retinal thickness (TRT), inner retinal thickness (IRT), and macular ganglion cell-inner plexiform layer (GCIPL) thickness.

Impact of race and ethnicity on glaucoma progression detection by perimetry and optical coherence tomography.

This study assessed the impact of race and ethnicity on longitudinal test variability and time to detect glaucoma progression using standard automated perimetry (SAP) and optical coherence tomography (OCT). The sample consisted of 47,003 SAP tests from 5402 eyes and 25,480 OCT tests from 4125 eyes, with 20% of participants self-identifying as Black or African American and 80% as White; 29% as Hispanic or Latino and 71% as Not Hispanic or Latino. Variability was measured using standard deviations of residuals from linear regression models for SAP mean deviation (MD) and OCT retinal nerve fiber layer (RNFL) thickness over time.

Male and female behavioral variability and morphine response in C57BL/6J, DBA/2J, and their BXD progeny following chronic stress exposure.

Drug addiction is a multifactorial syndrome in which genetic predispositions and exposure to environmental stressors constitute major risk factors for the early onset, escalation, and relapse of addictive behaviors. While it is well known that stress plays a key role in drug addiction, the genetic factors that make certain individuals particularly sensitive to stress and, thereby, more vulnerable to becoming addicted are unknown. In an effort to test a complex set of gene x environment interactions-specifically gene x chronic stress-here we leveraged a systems genetics resource: BXD recombinant inbred mice (BXD5, BXD8, BXD14, BXD22, BXD29, and BXD32) and their parental mouse lines, C57BL/6J and DBA/2J.

Nutritional composition, nitrogen-corrected true metabolizable energy, and standardized amino acid digestibility of palm kernel meal from several countries.

Extensive nutritional analyses were conducted for palm kernel meal (PKM) sourced from 5 countries. Two precision-fed rooster trials were conducted to evaluate the nitrogen-corrected true metabolizable energy (TME) and standardized amino acid (AA) digestibility of 10 PKM samples (PKM 1 to 10). The TME was determined using conventional Single Comb White Leghorn roosters, and standardized AA digestibility was determined using cecectomized roosters.

Changes in Medication Complexity and Post-Hospitalization Outcomes in Older Adults Hospitalized for Heart Failure.

Introduction: Medication regimen complexity may be an important risk factor for adverse outcomes in older adults with heart failure. However, increasing complexity is often necessary when prescribing guideline-directed medical therapy at the time of a heart failure hospitalization. We sought to determine whether increased medication regimen complexity following a heart failure hospitalization was associated with worse post-hospitalization outcomes.

Impact of the clinically approved BTK inhibitors on the conformation of full-length BTK and analysis of the development of BTK resistance mutations in chronic lymphocytic leukemia.

Inhibition of Bruton's tyrosine kinase (BTK) has proven to be highly effective in the treatment of B-cell malignancies such as chronic lymphocytic leukemia (CLL), autoimmune disorders, and multiple sclerosis. Since the approval of the first BTK inhibitor (BTKi), Ibrutinib, several other inhibitors including Acalabrutinib, Zanubrutinib, Tirabrutinib, and Pirtobrutinib have been clinically approved. All are covalent active site inhibitors, with the exception of the reversible active site inhibitor Pirtobrutinib.

Deep Proteome Coverage of Microglia Using a Streamlined Data-Independent Acquisition-Based Proteomic Workflow: Method Consideration for a Phenotypically Diverse Cell Type.

As the primary innate immune cells of the brain, microglia play a key role in various homeostatic and disease-related processes. To carry out their numerous functions, microglia adopt a wide range of phenotypic states. The proteomic landscape represents a more accurate molecular representation of these phenotypes; however, microglia present unique challenges for proteomic analysis.

New Sesterterpenes from the Antarctic Sponge sp.

Chemical investigation of the Antarctic sponge sp. has previously led to the identification of new suberitane derivatives, some of which show bioactivity toward respiratory syncytial virus (RSV). Our ongoing NMR-guided investigation of new specimens of the sponge resulted in the isolation of five new analogs (-), previously reported suberitenones A-D (-), and oxaspirosuberitenone ().

Epigenome-Wide and Methylation Risk Score Analysis of Body Mass Index Among People with HIV.

People with HIV (PWH) on antiretroviral therapy (ART) often gain weight, which increases their risk of type 2 diabetes and cardiovascular disease. The role of DNA methylation (DNAm) markers in obesity among PWH is understudied. This research explores the relationship between body mass index (BMI) and epigenetic patterns to better understand and manage obesity-related risks in PWH.

An Improved Sporozoite Seroneutralization Assay for the Identification of East Coast Fever Immune Correlates.

Background: Immune correlates of protection are ideal tools to predict treatment or vaccine efficacy. However, the accuracy of the immune correlate and the capability to robustly predict the outcome of a vaccine candidate are determined by the performance of the in vitro immunoassay used. Several sporozoite seroneutralization assays have previously been used to assess antibody functional activities; however, a common limitation has been the need for fresh material, target cells and sporozoites, and operator-to-operator bias.

Effectiveness of the BNT162b2 XBB.1.5-adapted vaccine against COVID-19 hospitalization related to the JN.1 variant in Europe: a test-negative case-control study using the id.DRIVE platform.

Background: Prior studies have reported lower effectiveness of XBB.1.5-adapted vaccines against hospitalization related to the Omicron JN.

Control of precision grip in children with heavy prenatal alcohol exposure.

Background: Fine motor skill deficits have been reported for children with histories of prenatal alcohol exposure, but little is known whether impaired motor skill extends to the regulation of precision grip control.

Methods: Children with (n = 15) and without (n = 17) histories of heavy prenatal alcohol exposure used their dominant hand to grasp, lift, and hold in space a small-instrumented object with a mass of 19 g. Object mass was also experimentally increased by separately adding two aluminum cubes with mass of 200 and 400 g.

Assessing initial/early aversion-resistant drinking across male and female alcohol-preferring and non-preferring rats.

Background: One trait of alcohol use disorder (AUD) is continuing to drink despite negative consequences. The current study investigated initial/early aversion-resistant drinking (ARD) across selectively bred alcohol-preferring lines to assess aversion resistance with minimal ethanol history and subsequent ethanol-seeking and drinking profiles. Additionally, ARD was assessed in alcohol-preferring and non-preferring rats using a sucrose reinforcer to determine if ARD may be a genetic risk factor for AUD.

Psychometric validation of the Diagnostic Assessment Research Tool: Alcohol use disorder module.

Aims: Structured clinical interviewing is considered the gold standard in psychiatric diagnosis. The Diagnostic Assessment Research Tool (DART) is a novel modularized, non-copywritten, semi-structured interview; however, no studies have examined the psychometric properties of its alcohol use disorder (AUD) module. The primary aims of this study were to: (i) validate the factor structure of the DART AUD module and (ii) examine measurement invariance across several key demographic and subgroup factors.

Prevalence and trends of pregnancy-related acute kidney injury in sub-Saharan Africa: a systematic review and meta-analysis.

Background: Pregnancy-Related Acute Kidney Injury (PRAKI) is an important contributor to maternal-fetal morbidity and mortality. The burden of PRAKI in sub-Saharan Africa is not well documented. We conducted a systematic literature review and meta-analysis to estimate the prevalence of PRAKI in sub-Saharan Africa.
