Designing and implementing the IDEAL Study: A randomized clinical trial of genotype disclosure for late-onset Alzheimer's disease in an urban Latino population.

Introduction: The (IDEAL) Study is a randomized clinical trial investigating the psychosocial, behavioral, and cognitive impacts of apolipoprotein E () genotype disclosure for late-onset Alzheimer's disease (AD) among Latinos.

Methods: We used address-based sampling to recruit English- and Spanish-speaking Latinos aged 40-64 living in northern Manhattan for a community-based Baseline Survey about their knowledge and opinions about AD. Participants eligible for the clinical trial were invited to complete an Introductory Session, including AD and genetics education and informed consent, before undergoing genotyping for .

Implementation of an Outpatient Clinical Pharmacy Service at an Adult Cystic Fibrosis Center.

Background: High treatment burden can adversely impact health outcomes in people with cystic fibrosis (PwCF). There is a continued need for medication adherence education and further research to evaluate impact of CF pharmacist interventions in an ambulatory care setting.

Objective(s): To evaluate whether pharmacist integration into an outpatient adult CF clinic can positively impact patient satisfaction and medication adherence through various pharmacist-based interventions.

Gut colonization with multidrug resistant organisms in the intensive care unit: a systematic review and meta-analysis.

Background: Gut colonization with multidrug-resistant organisms (MDRO) frequently precedes infection among patients in the intensive care unit (ICU), although the dynamics of colonization are not completely understood. We performed a systematic review and meta-analysis of ICU studies which described the cumulative incidence and rates of MDRO gut acquisition.

Methods: We systematically searched PubMed, Embase, and Web of Science for studies published from 2010 to 2023 reporting on gut acquisition of MDRO in the ICU.

Change in parental knowledge and beliefs about early childhood dental caries following a pragmatic community-based trial.

Objectives: To evaluate parent knowledge and belief changes following the MySmileBuddy (MSB) early childhood caries (ECC) intervention.

Methods: Pre- and post-intervention surveys were completed by 669 parents of children with visually-evident ECC from among 977 participants in a 6-12-month pragmatic community-based caries management trial administered by community health workers (CHWs). Six domains of knowledge about caries and motivating and facilitating determinants were assessed via 26 survey items.

mTOR Inhibition Prolongs Survival and Has Beneficial Effects on Heart Function After Onset of Lamin A/C Gene Mutation Cardiomyopathy in Mice.

Background: Mutations in encoding nuclear envelope proteins lamin A/C cause dilated cardiomyopathy. Activation of the AKT/mTOR (RAC-α serine/threonine-protein kinase/mammalian target of rapamycin) pathway is implicated as a potential pathophysiologic mechanism. The aim of this study was to assess whether pharmacological inhibition of mTOR signaling has beneficial effects on heart function and prolongs survival in a mouse model of the disease, after onset of heart failure.

Randomized adaptive selection trial of cryotherapy, compression therapy, and placebo to prevent taxane-induced peripheral neuropathy in patients with breast cancer.

Background: Chemotherapy-induced peripheral neuropathy (CIPN) is a common and debilitating adverse effect of taxane therapy. Small non-randomized studies in patients with early-stage breast cancer (ESBC) suggest both cryotherapy and compression therapy may prevent CIPN. It is unknown which is more effective.

Olfaction, body mass index, and quality of life with cystic fibrosis combination therapy.

Background: Triple-combination therapy of elexacaftor-tezacaftor-ivacaftor (ETI) has been shown to reduce morbidity and mortality in people with cystic fibrosis (PwCF). Although patient body mass index (BMI) favorably increases with ETI treatment, factors contributing to this improvement are poorly characterized. Olfaction contributes to appetite stimulation and anticipation of eating, where higher rates of olfactory impairment (OI) in PwCF may contribute to malnutrition and BMI instability in this population.

Feasibility Study of a Powder-Based Supplement Intervention for a future Synbiotic Trial in Breastfed Children from South Africa.

Background: Children who are HIV-exposed uninfected (HEU), i.e., born to mothers living with HIV despite not acquiring HIV infection themselves, have increased morbidity and mortality.

Acceptability and Feasibility of Providing Adherence Feedback Based on Tenofovir Diphosphate in Dried Blood Spots: Results from a Pilot Study Among Patients and Providers in Cape Town, South Africa.

Tenofovir diphosphate (TFV-DP) concentrations in dried blood spots (DBS) predict viral breakthrough, but their use remains understudied in real-world clinic settings. This pilot study examined acceptability, feasibility, and initial adherence outcomes of providing adherence feedback using TFV-DP concentrations on patient- and provider-levels in Cape Town, South Africa. We enrolled 60 persons with HIV (PWH) receiving tenofovir-containing ART attending a primary health clinic.

Comparing Predictive Ability of Two Objective Adherence Measures in a Community-Based Cohort on Antiretroviral Therapy in South Africa: Tenofovir Diphosphate Concentrations and Electronic Adherence Monitors.

Background: Electronic adherence (EA) and tenofovir diphosphate (TFV-DP) in dried blood spots (DBS) are objective measures of antiretroviral therapy (ART) adherence. We characterized the association between these measures in a prospective cohort of persons with HIV (PWH) on ART.

Setting: Four primary health clinics in Cape Town, South Africa.

Condomless Sex Among HIV-affected AYA in an Era of Undetectable = Untransmittable and Pre-exposure Prophylaxis.

Given poor adherence to treatment and prevention techniques, condomless sex jeopardizes adolescents and young adults (AYA) with perinatally-acquired HIV-infection (PHIV) or perinatal HIV-exposure who are uninfected (PHEU). We examined condomless sex and its association with PHIV-status, psychiatric disorder, and sociodemographics. Data come from a US-based study of primarily Black and Latinx AYAPHIV and AYAPHEU (N = 340).

Health Care Provider Decisions to Initiate Oral HIV Preexposure Prophylaxis in New York City Public Sexual Health Clinics.

Background: Oral HIV preexposure prophylaxis (PrEP) is safe and effective but underutilized. Health care providers' beliefs about PrEP and attitudes toward people who could benefit may affect PrEP access.

Methods: This mixed-methods study (2016-2018) was conducted in 8 New York City public sexual health clinics that implemented a PrEP program.

Mitigating Infectious morbidity and Growth deficits in HIV-exposed uninfected infanTs with human Milk Oligosaccharide (MIGH-T MO): a randomised trial protocol.

Introduction: Children who are HIV-exposed uninfected (HEU), that is, children who do not acquire HIV infection despite being born to mothers with HIV, have a higher risk of mortality, infectious morbidity and growth deficits than children who are HIV-unexposed uninfected (HUU). Prior research has focused on breast feeding and has pointed to changes in human milk oligosaccharides (HMOs) associated with maternal HIV that may influence the infant microbiome and thereby lead to these adverse outcomes. However, to our knowledge, no study has attempted to intervene along this pathway to reduce the occurrence of the adverse outcomes in children HEU.

Sex-Specific Pathways Lead to Statural Growth Impairment in Children with Crohn's Disease.

Objectives: To examine the underlying mechanisms that lead growth impairment to occur more commonly in males than females with Crohn's disease (CD).

Study Design: Children and adolescents with CD were enrolled in a prospective multicenter longitudinal cohort study. Height Z-score difference was computed as height Z-score based on chronological age (height chronological age-Z-score) minus height Z-score based on bone age (height bone age-Z-score) using longitudinal data.

RRM1 variants cause a mitochondrial DNA maintenance disorder via impaired de novo nucleotide synthesis.

Mitochondrial DNA (mtDNA) depletion/deletions syndromes (MDDS) encompass a clinically and etiologically heterogenous group of mitochondrial disorders caused by impaired mtDNA maintenance. Among the most frequent causes of MDDS are defects in nucleoside/nucleotide metabolism, which is critical for synthesis and homeostasis of the deoxynucleoside triphosphate (dNTP) substrates of mtDNA replication. A central enzyme for generating dNTPs is ribonucleotide reductase, a critical mediator of de novo nucleotide synthesis composed of catalytic RRM1 subunits in complex with RRM2 or p53R2.

Tumor Immune Microenvironment and Response to Neoadjuvant Chemotherapy in Hormone Receptor/HER2+ Early Stage Breast Cancer.

Background: Pathologic response at the time of surgery after neoadjuvant therapy for HER2 positive early breast cancer impacts both prognosis and subsequent adjuvant therapy. Comprehensive descriptions of the tumor microenvironment (TME) in patients with HER2 positive early breast cancer is not well described. We utilized standard stromal pathologist-assessed tumor infiltrating lymphocyte (TIL) quantification, quantitative multiplex immunofluorescence, and RNA-based gene pathway signatures to assess pretreatment TME characteristics associated pathologic complete response in patients with hormone receptor positive, HER2 positive early breast cancer treated in the neoadjuvant setting.

Assessing the effects of stress on feeding behaviors in laboratory mice.

Stress often affects eating behaviors, increasing caloric intake in some individuals and decreasing it in others. The determinants of feeding responses to stress are unknown, in part because this issue is rarely studied in rodents. We focused our efforts on the novelty-suppressed feeding (NSF) assay, which uses latency to eat as readout of anxiety-like behavior, but rarely assesses feeding per se.
