Blood-based diagnosis of pediatric tuberculosis: A prospective cohort study in South Africa and Dominican Republic.

Objectives: Pediatric tuberculosis (TB) diagnosis is complicated by challenges in obtaining invasive respiratory specimens that frequently contain few Mycobacterium tuberculosis (Mtb) bacilli. We report the diagnostic performance of an Mtb antigen-derived peptide (MAP-TB) assay and its ability to monitor TB treatment response.

Methods: Study cohorts enrolled children who presented with presumptive TB at two hospitals in South Africa from 2012 to 2017 (157 children aged <13 years) and at community-based clinics in the Dominican Republic from 2019 to 2023 (101 children aged <18 years).

Safety and Immunogenicity of an mRNA-1273 Booster in Children.

Background: A 2-dose mRNA-1273 primary series in children aged 6 months-5 years (25 µg) and 6-11 years (50 µg) had an acceptable safety profile and was immunogenic in the phase 2/3 KidCOVE study. We present data from KidCOVE participants who received an mRNA-1273 booster dose.

Methods: An mRNA-1273 booster dose (10 µg for children aged 6 months-5 years; 25 µg for children aged 6-11 years; age groups based on participant age at enrollment) was administered ≥6 months after primary series completion.

Validation of an interprofessional education search strategy in PubMed to optimize IPE literature searching.

Objective: With exponential growth in the publication of interprofessional education (IPE) research studies, it has become more difficult to find relevant literature and stay abreast of the latest research. To address this gap, we developed, evaluated, and validated search strategies for IPE studies in PubMed, to improve future access to and synthesis of IPE research. These search strategies, or search hedges, provide comprehensive, validated sets of search terms for IPE publications.

Pharmacokinetics and Safety of Remdesivir in Pregnant and Nonpregnant Women With COVID-19: Results From IMPAACT 2032.

Background: Pregnant people with coronavirus disease 2019 (COVID-19) experience higher risk for severe disease and adverse pregnancy outcomes, but no pharmacokinetic (PK) data exist to support dosing of COVID-19 therapeutics during pregnancy. We report PK and safety data for intravenous remdesivir in pregnancy.

Methods: IMPAACT 2032 was a phase 4 prospective, open-label, nonrandomized opportunistic study of hospitalized pregnant and nonpregnant women receiving intravenous remdesivir as part of clinical care.

Are Family Factors Differentially Associated with Externalizing Symptoms Among Youth with Perinatally Acquired HIV?

Youth with perinatally-acquired HIV (PHIV) face unique psychosocial stressors. They are at risk for externalizing problems, including symptoms of oppositional defiant disorder, conduct disorder (CD), and attention-deficit/hyperactivity disorder (ADHD), as well as risk-taking behaviors, such as substance use (SU). Although family factors have been differentially associated with externalizing and SU behaviors based on youth sex in prior research, there is a dearth of literature considering these processes among youth with PHIV.

Breastfeeding in the United States Among Women With HIV: Con Viewpoint.

To breast feed or not has long been a difficult question for women with human immunodeficiency virus (HIV) in high-income countries, as undetectable HIV in maternal plasma does not translate to zero risk of transmission while breastfeeding, and clean water and formula are readily available. Recent, and more permissive, changes in US and other high-income-country guidelines regarding breastfeeding underscore this issue and acknowledge the information gaps that are essential for informed maternal choice and provider management. These include lack of guidance as to routine monitoring of mothers during lactation, type and length of prophylaxis for infants, and lack of data on factors associated with increased breast-milk viral load and risk of transmission.

Prosocial Interventions and Health Outcomes: A Systematic Review and Meta-Analysis.

Importance: Prosocial interventions encourage voluntary actions that benefit others. Community solidarity in response to the COVID-19 pandemic, expanding mutual aid programs, and health workforce issues have accelerated prosocial health interventions.

Objective: To investigate the association of prosocial interventions with health outcomes in clinical trials and observational studies.

Long-acting antiretrovirals and HIV treatment adherence.

Intramuscular injection of long-acting cabotegravir and rilpivirine is a novel, long-acting antiretroviral therapy (ART) combination approved for use as a fully suppressive regimen for people living with HIV. Long-acting cabotegravir with rilpivirine ART has reduced required dosing frequency from once daily to once every month or every 2 months injections. This new era of long-acting ART, which includes other antiretrovirals and formulations in various stages of clinical development, holds tremendous promise to change the standard of HIV treatment.

Developing tuberculosis vaccines for people with HIV: consensus statements from an international expert panel.

New tuberculosis vaccine candidates that are in the development pipeline need to be studied in people with HIV, who are at high risk of acquiring Mycobacterium tuberculosis infection and tuberculosis disease and tend to develop less robust vaccine-induced immune responses. To address the gaps in developing tuberculosis vaccines for people with HIV, a series of symposia was held that posed six framing questions to a panel of international experts: What is the use case or rationale for developing tuberculosis vaccines? What is the landscape of tuberculosis vaccines? Which vaccine candidates should be prioritised? What are the tuberculosis vaccine trial design considerations? What is the role of immunological correlates of protection? What are the gaps in preclinical models for studying tuberculosis vaccines? The international expert panel formulated consensus statements to each of the framing questions, with the intention of informing tuberculosis vaccine development and the prioritisation of clinical trials for inclusion of people with HIV.

Clinical and population-based study design considerations to accelerate the investigation of new antiretrovirals during pregnancy.

Introduction: Pregnant women are routinely excluded from clinical trials, leading to the absence or delay in even the most basic pharmacokinetic (PK) information needed for dosing in pregnancy. When available, pregnancy PK studies use a small sample size, resulting in limited safety information. We discuss key study design elements that may enhance the timely availability of pregnancy data, including the role and timing of randomized controlled trials (RCTs) to evaluate pregnancy safety; efficacy and safety outcome measures; stand-alone protocols, platform trials, single arm studies, sample size and the effect that follow-up time during gestation has on analysis interpretations; and observational studies.

Effectiveness of a community-based intervention to prevent childhood TB in Lesotho.

Child contact management (CCM) is a recognized strategy to prevent TB; however, implementation is suboptimal. PREVENT was a cluster-randomized trial that evaluated the effectiveness and acceptability of a community-based intervention (CBI) to improve CCM in Lesotho. Ten health facilities (HFs) were randomized to CBI or standard-of-care (SOC).

Antibiotic use among admitted pediatric patients in the United States with status asthmaticus before and during the COVID-19 pandemic.

Hospital admission trends of children with status asthmaticus diminished during the Coronavirus-19 (COVID-19) pandemic of 2020, possibly secondary to several factors such as school closures and use of face masks. What effect this had on antibiotic prescribing practices has yet to be described. The objective of our study was to evaluate the use of antibiotics in hospitalized children with a diagnosis of status asthmaticus before and during the COVID pandemic.

Exploring the value of Mycobacterium tuberculosis modified lipoprotein as a potential biomarker for TB detection in children.

Background: Current TB diagnostic methods available have been developed for adults and development efforts have neglected the differences in disease and sampling that occur between adults and children. Diagnostic challenges are even greater in HIV co-infected children and infants.

Methods And Results: We established a sandwich ELISA assay to detect Mycobacterium tuberculosis modified lipoprotein (TLP) ex vivo in plasma.

Improving child tuberculosis contact identification and screening in Lesotho: Results from a mixed-methods cluster-randomized implementation science study.

Background: Child tuberculosis (TB) contact management is recommended for preventing TB in children but its implementation is suboptimal in high TB/HIV-burden settings. The PREVENT Study was a mixed-methods, clustered-randomized implementation study that evaluated the effectiveness and acceptability of a community-based intervention (CBI) to improve child TB contact management in Lesotho, a high TB burden country.

Methods: Ten health facilities were randomized to CBI or standard of care (SOC).

Evaluation of a serum-based antigen test for tuberculosis in HIV-exposed infants: a diagnostic accuracy study.

Background: Non-sputum methods are urgently needed to improve tuberculosis diagnosis and treatment monitoring in children. This study evaluated the ability of a serum assay quantifying a species-specific peptide of the Mycobacterium tuberculosis CFP-10 virulence factor via nanotechnology and matrix-assisted laser desorption ionization time-of-flight mass spectrometry to diagnose tuberculosis in HIV-infected and HIV-uninfected infants.

Methods: Serum CFP-10 peptide signal was blinded evaluated in cryopreserved sera of 519 BCG-immunized, HIV-exposed infants (284 HIV-infected, 235 HIV-uninfected) from a multi-center randomized placebo-controlled isoniazid prophylaxis trial conducted in southern Africa between 2004 and 2008, who were followed up to 192 weeks for Mtb infection and TB.

Neurocognitive Plasticity Is Associated with Cardiorespiratory Fitness Following Physical Exercise in Older Adults with Amnestic Mild Cognitive Impairment.

Background: Aerobic training has been shown to promote structural and functional neurocognitive plasticity in cognitively intact older adults. However, little is known about the neuroplastic potential of aerobic exercise in individuals at risk of Alzheimer's disease (AD) and dementia.

Objective: We aimed to explore the effect of aerobic exercise intervention and cardiorespiratory fitness improvement on brain and cognitive functions in older adults with amnestic mild cognitive impairment (aMCI).

Maximal aerobic capacity is associated with hippocampal cognitive reserve in older adults with amnestic mild cognitive impairment.

Maximal aerobic capacity (MAC) has been associated with preserved neural tissue or brain maintenance (BM) in healthy older adults, including the hippocampus. Amnestic mild cognitive impairment (aMCI) is considered a prodromal stage of Alzheimer's disease. While aMCI is characterized by hippocampal deterioration, the MAC-hippocampal relationship in these patients is not well understood.

Comparison of COVID-19 infections among healthcare workers and non-healthcare workers.

Objectives: Healthcare workers face distinct occupational challenges that affect their personal health, especially during a pandemic. In this study we compare the characteristics and outcomes of Covid-19 patients who are and who are not healthcare workers (HCW).

Methods: We retrospectively analyzed a cohort of 2,842 adult patients with known HCW status and a positive SARS-CoV-2 RT-PCR test presenting to a large academic medical center emergency department (ED) in New York State from March 21 2020 through June 2020.

Understanding Pediatric Drug Lag Time: Review of Selected Drug Package Inserts.

The wait for a pharmaceutical drug to become approved by the FDA for pediatrics lasts approximately 8 years longer than that for adults. One of the reasons given is the concern that simultaneous pediatric and adult trials may affect licensing in adults. We reviewed drug package inserts obtained from the FDA database for 5 selected agents for the years prior to and after being FDA approved for pediatric use.

Severe Acute Respiratory Syndrome Coronavirus 2 Clinical Syndromes and Predictors of Disease Severity in Hospitalized Children and Youth.

Objective: To characterize the demographic and clinical features of pediatric severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) syndromes and identify admission variables predictive of disease severity.

Study Design: We conducted a multicenter, retrospective, and prospective study of pediatric patients hospitalized with acute SARS-CoV-2 infections and multisystem inflammatory syndrome in children (MIS-C) at 8 sites in New York, New Jersey, and Connecticut.

Results: We identified 281 hospitalized patients with SARS-CoV-2 infections and divided them into 3 groups based on clinical features.
