Immunogenicity and safety following a homologous booster dose of a SARS-CoV-2 recombinant spike protein vaccine with Matrix-M adjuvant (NVX-CoV2373) versus a primary series in people living with and without HIV-1 infection in South Africa: A randomized crossover phase 2a/2b trial.

COVID-19 remains a global public health issue and an improved understanding of vaccine performance in immunocompromised individuals, including people living with HIV (PLWH), is needed. Initial data from the present study's pre-crossover/booster phase were previously reported. This phase 2a/b clinical trial in South Africa (2019nCoV-501/NCT04533399) revisits 1:1 randomly assigned HIV-negative adults (18-84 years) and medically stable PLWH (18-64 years) who previously received two NVX-CoV2373 doses (5 μg recombinant Spike protein with 50 μg Matrix-M™ adjuvant) or placebo.

Barriers to Serious Illness Conversations Among Patients with Advanced Cancer: A Qualitative Study.

Purpose: Serious illness conversations (SICs) are discussions between clinicians and cancer patients about illness understanding, information preferences, and goals of care. Interventions to prompt SICs increase SIC rates and improve care delivery near the end of life. This embedded substudy examined SIC barriers and facilitators among "refractory" patients without an SIC despite enrollment in an SIC clinical trial.

Tackling inequalities in preconception health and care: barriers, facilitators and recommendations for action from the 2023 UK preconception EMCR network conference.

Reducing inequalities in preconception health and care is critical to improving the health and life chances of current and future generations. A hybrid workshop was held at the 2023 UK Preconception Early and Mid-Career Researchers (EMCR) Network conference to co-develop recommendations on ways to address inequalities in preconception health and care. The workshop engaged multi-disciplinary professionals across diverse career stages and people with lived experience (total = 69).

Impact of Senescent Cell-Derived Extracellular Vesicles on Innate Immune Cell Function.

Extracellular vesicles (EVs) are components of the senescence-associated secretory phenotype (SASP) that influence cellular functions via their cargo. Here, the interaction between EVs derived from senescent (SEVs) and non-senescent (N-SEVs) fibroblasts and the immune system is investigated. Via endocytosis, SEVs are phagocytosed by monocytes, neutrophils, and B cells.

Key informant perspectives on overcoming HPV vaccination barriers in low-immunization NY counties.

Human papillomavirus (HPV) infection is an important public health concern, with nearly 2,900 cases of HPV-related cancers reported in New York State (NYS) each year. Despite concerted efforts to enhance vaccine uptake in NYS, HPV vaccination rates among 13-15-year-olds failed to meet the 2020 healthy People target, and continue to lag behind the 2030 goal, of 80%. In counties with low immunization levels, understanding factors influencing decision-making among unvaccinated adolescents is crucial.

Med13 is required for efficient P-body recruitment and autophagic degradation of Edc3 following nitrogen starvation.

The Cdk8 kinase module (CKM), a conserved, detachable unit of the Mediator complex, plays a vital role in regulating transcription and communicating stress signals from the nucleus to other organelles. Here, we describe a new transcription-independent role for Med13, a CKM scaffold protein, following nitrogen starvation. In , nitrogen starvation triggers Med13 to translocate to the cytoplasm.

NK cell line modified to express a potent, DR5 specific variant of TRAIL, show enhanced cytotoxicity in ovarian cancer models.

Objective: Ovarian cancer is a lethal gynaecological malignancy with unsatisfactory 5 year survival rates of 30-50 %. Cell immunotherapy is a promising new cancer treatment where immune cells, such as Natural Killer (NK) cells, are administered to enable the patient to fight cancer through direct cytotoxicity. NK cells orchestrate an adaptive immune response by enabling the release of tumour antigens.

A global perspective: Access to mental health care for perinatal populations.

Perinatal mental health care differs around the world. We provide a global perspective on the current status of service provision, barriers and facilitators to access, and strategies to improve access in high-income and low- and middle-income countries across five continents (Asia, Africa, Europe, North America and South America). Many of the countries considered do not have universal healthcare coverage.

Breeding Novel Chemistry in Willow: New Hetero Diels-Alder Cyclodimers from Arbusculoidin and Salicortin Suggest Parallel Biosynthetic Pathways.

An investigation of phenolic glycosides extracted from germplasm revealed that arbusculoidin (benzyl 1--β-d-glucopyranosyl-1-hydroxy-6-oxo-2-cyclohexenyl carboxylate) and its enolic 6-glycoside isomer, isoarbusculoidin, are widespread across the Salix family. An analysis of natural hybrid species and progeny from a willow breeding programme demonstrated that the putative biosynthetic pathway leading to the salicinoid family of phenolic glycosides runs in parallel to a "benzyl"-based pathway to arbusculoidin. The introduction of a known Diels-Alder reaction trait from , as well as an acylation trait, into progeny containing both salicyl- and benzyl- pathways caused the formation of all possible hetero-cyclodimers from mixtures of reactive dienone (acyl)glycosides that participated in cross-over reactions.

Lost in the System: Responsibilisation and Burden for Women With Multiple Long-Term Health Conditions During Pregnancy.

Introduction: Over a fifth of pregnant women are living with multiple long-term health conditions, which is associated with increased risks of adverse outcomes for mothers and infants. While there are many examples of research exploring individuals' experiences and care pathways for pregnancy with a single health condition, evidence relating to multiple health conditions is limited. This study aimed to explore experiences and care of women with multiple long-term health conditions around the time of pregnancy.

Unexpected Seizure Activity in the Setting of Lamotrigine Toxicity.

Lamotrigine, a widely utilized broad-spectrum anticonvulsant, is commonly prescribed for epilepsy management and bipolar mood disorders. Despite its extensive clinical usage, instances of lamotrigine overdose are underreported. Here, we present a case involving acute encephalopathy and seizure onset following an intentional lamotrigine overdose.

Unintended pregnancy and contraception use among African women living with HIV: Baseline analysis of the multi-country US PEPFAR PROMOTE cohort.

Background: About 90% of unintended pregnancies are attributed to non-use of effective contraception-tubal ligation, or reversible effective contraception (REC) including injectables, oral pills, intra-uterine contraceptive device (IUCD), and implant. We assessed the prevalence of unintended pregnancy and factors associated with using RECs, and Long-Acting-Reversible-Contraceptives (LARCs)-implants and IUCDs, among women living with HIV (WLHIV) receiving antiretroviral therapy (ART).

Methods: We conducted cross-sectional analyses of the US-PEPFAR PROMOTE study WLHIV on ART at enrollment.

The Impact of Regular Screening and Lifestyle Modification on Cardiovascular Disease Risk Factors in South African Women Living With HIV.

Background: The Integration of cardiovascular disease SCreening and prevention in the HIV MAnagement plan for women of reproductive age study set out to determine the effectiveness of screening and lifestyle modification in modifying cardiovascular disease (CVD) risk factors in women living with HIV (WLHIV).

Methods: In this prospective, quasiexperimental, intervention study, WLHIV aged 18-<50 years were enrolled from 2 clinics (intervention [I-arm]) and (control arms [C-arm]) in Umlazi, South Africa, between November 2018 and May 2019. Women in the I-arm received lifestyle modification advice on diet, physical activity, alcohol use, and smoking cessation and underwent annual screening for CVD risk.

Senescent cell-derived extracellular vesicles as potential mediators of innate immunosenescence and inflammaging.

Ageing is accompanied by a decline in immune function (immunosenescence), increased inflammation (inflammaging), and more senescent cells which together contribute to age-related disease and infection susceptibility. The innate immune system is the front-line defence against infection and cancer and is also involved in the removal of senescent cells, so preventing innate immunosenescence and inflammaging is vital for health in older age. Extracellular vesicles (EVs) modulate many aspects of innate immune function, including chemotaxis, anti-microbial responses, and immune regulation.

Weight Changes and Adverse Pregnancy Outcomes With Dolutegravir- and Tenofovir Alafenamide Fumarate-Containing Antiretroviral Treatment Regimens During Pregnancy and Postpartum.

Background: We evaluated associations between antepartum weight change and adverse pregnancy outcomes and between antiretroviral therapy (ART) regimens and week 50 postpartum body mass index in IMPAACT 2010.

Methods: Women with human immunodeficiency virus (HIV)-1 in 9 countries were randomized 1:1:1 at 14-28 weeks' gestational age (GA) to start dolutegravir (DTG) + emtricitabine (FTC)/tenofovir alafenamide fumarate (TAF) versus DTG + FTC/tenofovir disoproxil fumarate (TDF) versus efavirenz (EFV)/FTC/TDF. Insufficient antepartum weight gain was defined using Institute of Medicine guidelines.

The Challenge of Weight Stigma for Women in the Preconception Period: Workshop Recommendations for Action from the 5th European Conference on Preconception Health and Care.

Weight stigma is a well-recognised public health issue affecting many members of society including women during the preconception period. The impacts of preconception weight stigma on women are significant and may result in decreased access to and uptake of healthcare, and mental health concerns. The consequences of this weight stigma may translate to negative maternal outcomes and even intergenerational effects on the child.

Intermittent actuation attenuates fibrotic behaviour of myofibroblasts.

The foreign body response (FBR) to implanted materials culminates in the deposition of a hypo-permeable, collagen rich fibrotic capsule by myofibroblast cells at the implant site. The fibrotic capsule can be deleterious to the function of some medical implants as it can isolate the implant from the host environment. Modulation of fibrotic capsule formation has been achieved using intermittent actuation of drug delivery implants, however the mechanisms underlying this response are not well understood.

Ksp1 is an autophagic receptor protein for the Snx4-assisted autophagy of Ssn2/Med13.

Ksp1 is a casein II-like kinase whose activity prevents aberrant macroautophagy/autophagy induction in nutrient-rich conditions in yeast. Here, we describe a kinase-independent role of Ksp1 as a novel autophagic receptor protein for Ssn2/Med13, a known cargo of Snx4-assisted autophagy of transcription factors. In this pathway, a subset of conserved transcriptional regulators, Ssn2/Med13, Rim15, and Msn2, are selectively targeted for vacuolar proteolysis following nitrogen starvation, assisted by the sorting nexin heterodimer Snx4-Atg20.

Breastfeeding Among Women Living With HIV in the Era of Lifelong ART: An Observational Multicountry Study in Eastern and Southern Africa.
