Background/objectives: Sleep problems are frequently experienced and play an important role in inflammation and disease risk. US Montmorency tart cherries (MTC) improve sleep outcomes in previous studies, but studies in individuals with overweight and obesity are lacking.

Methods: A total of 34 individuals with sleep issues and overweight or obesity (BMI: 32.

In multiple sclerosis (MS) the B cell depleting drug ocrelizumab has shown high efficacy in reducing inflammatory activity. Its mechanism of action is unclear due to B cell subset complexity and unknown roles in pathogenesis. Here, we comprehensively phenotyped and quantitated peripheral blood B cell subsets before and after ocrelizumab infusion to gain insight into the fate of B cell subsets with pathogenic potential.

Ethical issues arise in the context of implementation science that may differ from those encountered in other research settings. This report, developed out of a workshop convened by the Center for Translation Research and Implementation Science within the United States National Heart, Lung, and Blood Institute, identifies six key themes that are important to the assessment of ethical dimensions of implementation science. First, addressing ethical challenges in implementation science does not require new ethical principles, commitments, or regulations.

Tertiary lymphoid structures (TLSs) are formed in tissues targeted by chronic inflammation processes, such as infection and autoimmunity. In Sjögren's disease, the organization of immune cells into TLS is an important part of disease progression. Here, we investigated the dynamics of tissue resident macrophages in the induction and expansion of salivary gland TLS.

Article Synopsis
  • - This study analyzed how brentuximab vedotin (BV), an antibody-drug conjugate, behaves in the body (pharmacokinetics) and how it affects response rates in patients with blood cancers, including both adults and children.
  • - It involved data from multiple studies, showing that the drug's exposure levels were similar in adolescents (12-18 years) compared to adults, but lower in younger children (2-12 years), with a noted overall response rate of 60% in the younger group.
  • - The findings suggest that the dosing of BV should be based on body weight rather than age, as no significant differences in effectiveness or severe side effects were found between the age groups.

Purpose: The purpose of the study was to evaluate the relationships between brentuximab vedotin (BV) pharmacokinetics, age, and body weight (BW) with efficacy and safety in pediatric and young adult patients with previously untreated, high-risk classical Hodgkin lymphoma in the phase III AHOD1331 study.

Experimental Design: Overall, 296 patients (age 2-21 years) in the overall population were randomized to and received BV + chemotherapy; the pharmacokinetic subpopulation comprised 24 patients (age <13 years). Age- and/or BW-based (pharmacokinetic surrogates) subgroup analyses of efficacy and safety were conducted for the overall population.

Article Synopsis
  • The pathogenesis of systemic lupus erythematosus (SLE) is significantly influenced by toll-like receptors (TLRs), especially TLR7, TLR8, and TLR9, with TLR7 overexpression linked to more severe cases of SLE.
  • Genetic factors, including the location of these receptors on the X-chromosome, contribute to SLE's higher prevalence in females, while the absence of TLR8 and TLR9 can worsen TLR7's effects, leading to increased disease severity.
  • Research suggests that targeting TLRs, alongside identifying specific markers for age-associated B cells (ABCs) which produce autoantibodies, could lead to new therapeutic approaches, with existing treatments

Article Synopsis
  • Tricuspid valve annuloplasty (TA) during mitral valve repair (MVr) increases the risk of needing a permanent pacemaker (PPM) post-surgery, with a higher 90-day PPM implantation rate for MVr with TA (14.0%) compared to isolated MVr (7.7%).
  • This study analyzed data from New York and California between 2004 and 2019 to evaluate the long-term effects of PPM implantation on survival and complications like heart failure hospitalization and endocarditis.
  • Results indicated that PPM recipients had significantly reduced long-term survival and higher risks of heart failure hospitalizations and endocarditis, regardless of whether they underwent isolated MVr or MVr with TA.

In controlled organ donation after circulatory determination of death (cDCDD), accurate and timely death determination is critical, yet knowledge gaps persist. Further research to improve the science of defining and determining death by circulatory criteria is therefore warranted. In a workshop sponsored by the National Heart, Lung, and Blood Institute, experts identified research opportunities pertaining to scientific, conceptual, and ethical understandings of DCDD and associated technologies.

Xenotransplantation offers the potential to meet the critical need for heart and lung transplantation presently constrained by the current human donor organ supply. Much was learned over the past decades regarding gene editing to prevent the immune activation and inflammation that cause early organ injury, and strategies for maintenance of immunosuppression to promote longer-term xenograft survival. However, many scientific questions remain regarding further requirements for genetic modification of donor organs, appropriate contexts for xenotransplantation research (including nonhuman primates, recently deceased humans, and living human recipients), and risk of xenozoonotic disease transmission.

Obeldesivir (ODV, GS-5245) is an orally administered prodrug of the parent nucleoside of remdesivir (RDV) and is presently in phase 3 trials for COVID-19 treatment. In this work, we show that ODV and its circulating parent nucleoside metabolite, GS-441524, have similar in vitro antiviral activity against filoviruses, including Marburg virus, Ebola virus, and Sudan virus (SUDV). We also report that once-daily oral ODV treatment of cynomolgus monkeys for 10 days beginning 24 hours after SUDV exposure confers 100% protection against lethal infection.

Lassa fever (LF) is an acute viral illness that causes thousands of deaths annually in West Africa. There are currently no Lassa virus (LASV) vaccines or antivirals approved for human use. Recently, we showed that combinations of broadly neutralizing human monoclonal antibodies (BNhuMAbs) known as Arevirumab-2 or Arevirumab-3 protected up to 100% of cynomolgus macaques against challenge with diverse lineages of LASV when treatment was initiated at advanced stages of disease.

As part of the non-clinical safety package characterizing bamlanivimab (SARS-CoV-2 neutralizing monoclonal antibody), the risk profile for antibody-dependent enhancement of infection (ADE) was evaluated in vitro and in an African green monkey (AGM) model of COVID-19. In vitro ADE assays in primary human macrophage, Raji, or THP-1 cells were used to evaluate enhancement of viral infection. Bamlanivimab binding to C1q, FcR, and cell-based effector activity was also assessed.

Background: In the UK, the number of new HIV diagnoses among gay and bisexual men who have sex with men (GBMSM) has decreased substantially. We aimed to understand the contribution of different interventions in reducing HIV incidence so far; to estimate future HIV incidence with continuation of current policies and with further scaling up of current interventions; and to estimate the maximum additional annual cost that should be spent towards these interventions for them to offer value for money.

Methods: We calibrated a dynamic, individual-based, stochastic simulation model, the HIV Synthesis Model, to multiple sources of data on HIV among GBMSM aged 15 years or older in the UK.
