Integration of 168,000 samples reveals global patterns of the human gut microbiome.

The factors shaping human microbiome variation are a major focus of biomedical research. While other fields have used large sequencing compendia to extract insights requiring otherwise impractical sample sizes, the microbiome field has lacked a comparably sized resource for the 16S rRNA gene amplicon sequencing commonly used to quantify microbiome composition. To address this gap, we processed 168,464 publicly available human gut microbiome samples with a uniform pipeline.

Analysis of Online Crowdfunding Among Patients Pursuing Metabolic and Bariatric Surgery in the United States.

Background: The Seychelles COVID-19 vaccination campaign was initiated using two different vaccines during the first wave of the pandemic in 2021. This observational study estimated vaccine effectiveness against severe outcomes (hospitalisation and/or death) from individuals infected with COVID-19 in the Seychelles adult population during Beta and Delta variant transmission.

Methods: This nationwide retrospective cohort study included all Seychellois residents aged ≥ 18 years who tested positive by RT-PCR or rapid antigen test for COVID-19 between January 25, 2021, and June 30, 2021.

A hybrid digital parenting programme to prevent abuse of adolescents in Tanzania: study protocol for a pragmatic cluster-randomised controlled trial.

Background: Evidence-based parenting programmes have strong evidence in preventing and mitigating violence, but in-person programmes are challenging to deliver at scale. ParentApp is an open-source, offline-first app-based adaptation of the Parenting for Lifelong Health for Parents and Teens programme to promote playful and positive parenting, reduce risks for sexual violence victimisation, and prevent violence against adolescents. This study aims to evaluate the effectiveness and cost-effectiveness of ParentApp compared to an attention-control group.

Multi-omic approaches for host-microbiome data integration.

The gut microbiome interacts with the host through complex networks that affect physiology and health outcomes. It is becoming clear that these interactions can be measured across many different omics layers, including the genome, transcriptome, epigenome, metabolome, and proteome, among others. Multi-omic studies of the microbiome can provide insight into the mechanisms underlying host-microbe interactions.

A Review of Incretin Therapies Approved and in Late-Stage Development for Overweight and Obesity Management.

Objective: To review clinical trial data for incretin therapies that are approved or in late-stage development for overweight or obesity management, along with clinical implications of these therapies and future directions.

Methods: We searched for clinical trials involving incretin therapies studied specifically for overweight or obesity management in ClinicalTrials.gov and PubMed from registry inception through December 2023.

Induction of Siglec-FCD101 eosinophils in the lungs following murine hookworm infection.

Helminth-induced eosinophils accumulate around the parasite at the site of infection, or in parasite-damaged tissues well after the helminth has left the site. The role of helminth-elicited eosinophils in mediating parasite control is complex. While they may contribute to direct parasite-killing and tissue repair, their involvement in long-term immunopathogenesis is a concern.

Integrated vs non-integrated treatment outcomes in dual diagnosis disorders: A systematic review.

Background: The incidence of dual diagnosis (DD) (i.e. substance use disorders [SUD] and co-occurring mental disorders) is widespread; however, they vary widely in permutation and combination.

A Water-Soluble Polymer-Lumefantrine Conjugate for the Intravenous Treatment of Severe Malaria.

Uncomplicated malaria is effectively treated with oral artemisinin-based combination therapy (ACT). Yet, there is an unmet clinical need for the intravenous treatment of the more fatal severe malaria. There is no combination intravenous therapy for uncomplicated due to the nonavailability of a water-soluble partner drug for the artemisinin, artesunate.

Use of Continuous Glucose Monitoring in Older Adults: A Review of Benefits, Challenges and Future Directions.

Many new technologies have been developed over the past decade, and these have substantially changed the way diabetes is managed. Continuous glucose monitoring is now the standard of care for many people living with diabetes, and among its numerous benefits, it has been shown to improve glycaemic outcomes and enhance quality of life. Older adults carry a high burden of diabetes and have a high risk of hypo-glycaemia and hypo-glycaemic unawareness, and continuous glucose monitoring can help to improve glycaemic management in this vulnerable population.

Indoor Versus Outdoor: Does Occupational Sunlight Exposure Increase Melanoma Risk? A Systematic Review.

Introduction: Melanoma is the fifth most common cancer diagnosed in the United States, representing 5.6% of all new cancer cases. There are conflicting reports correlating a relationship between primarily outdoor occupations, associated with increased exposure to direct sunlight, and the incidence of cutaneous melanoma.

Rho family GTPase signaling through type II p21-activated kinases.

Signaling from the Rho family small GTPases controls a wide range of signaling outcomes. Key among the downstream effectors for many of the Rho GTPases are the p21-activated kinases, or PAK group. The PAK family comprises two types, the type I PAKs (PAK1, 2 and 3) and the type II PAKs (PAK4, 5 and 6), which have distinct structures and mechanisms of regulation.

'It provides practical tips, practical solutions!': acceptability, usability, and satisfaction of a digital parenting intervention across African countries.

The parenting evidence base is well established, and the question is how best to transfer the evidence to an app. App-based interventions could expand access to evidence-based parenting support; however, current provision lacks rigorous evidence, shows low user engagement, and is primarily for commercial gain. This study aimed at testing the feasibility and acceptability of ParentApp for Teens, an open-source, mobile parenting intervention application based on the Parenting for Lifelong Health Teens programme targeting parents of teens.

'Tipping the balance' - an evaluation of COVID-19 parenting resources developed and adapted for child protection during global emergency responses.

Parenting was severely affected by lockdown, school closure, illness, movement restrictions and the many sudden changes wrought by the global emergence of COVID-19. Responding to the need for a rapid emergency response to support parents and caregivers, a consortium of providers developed a suite of COVID-19 parenting resources based on evidence-based parenting interventions. Launched in March 2020, these were adapted for online use, with versions in over 100 languages, and the possibility for downloading, radio, and oral provision.

Targeting Airway Smooth Muscle Hypertrophy in Asthma: An Approach Whose Time Has Come.

Airway smooth muscle (ASM) cell dysfunction is an important component of several obstructive pulmonary diseases, particularly asthma. External stimuli such as allergens, dust, air pollutants, and change in environmental temperatures provoke ASM cell hypertrophy, proliferation, and migration without adequate mechanistic controls. ASM cells can switch between quiescent, migratory, and proliferative phenotypes in response to extracellular matrix proteins, growth factors, and other soluble mediators.

Machine learning prediction of methionine and tryptophan photooxidation susceptibility.

Photooxidation of methionine (Met) and tryptophan (Trp) residues is common and includes major degradation pathways that often pose a serious threat to the success of therapeutic proteins. Oxidation impacts all steps of protein production, manufacturing, and shelf life. Prediction of oxidation liability as early as possible in development is important because many more candidate drugs are discovered than can be tested experimentally.

Il4ra-independent vaginal eosinophil accumulation following helminth infection exacerbates epithelial ulcerative pathology of HSV-2 infection.

How helminths influence the pathogenesis of sexually transmitted viral infections is not comprehensively understood. Here, we show that an acute helminth infection (Nippostrongylus brasiliensis [Nb]) induced a type 2 immune profile in the female genital tract (FGT). This leads to heightened epithelial ulceration and pathology in subsequent herpes simplex virus (HSV)-2 infection.

Clinic and care: associations with adolescent antiretroviral therapy adherence in a prospective cohort in South Africa.

Objective: Adolescent antiretroviral treatment (ART) adherence remains critically low. We lack research testing protective factors across both clinic and care environments.

Design: A prospective cohort of adolescents living with HIV (sample n = 969, 55% girls, baseline mean age 13.

Impact of Helminth Infections on Female Reproductive Health and Associated Diseases.

A growing body of knowledge exists on the influence of helminth infections on allergies and unrelated infections in the lung and gastrointestinal (GI) mucosa. However, the bystander effects of helminth infections on the female genital mucosa and reproductive health is understudied but important considering the high prevalence of helminth exposure and sexually transmitted infections in low- and middle-income countries (LMICs). In this review, we explore current knowledge about the direct and systemic effects of helminth infections on unrelated diseases.
