Use of Practices to Reduce of Sudden Unexpected Infant Death among Caregivers of Opioid Exposed Newborns.

Objectives: Sudden unexpected infant death (SUID) occurs disproportionately among opioid exposed newborns (OENs) compared to those unexposed. The extent that primary caregivers of OENs adhere to SUID-reducing infant care practices is unknown. We examined rates of SUID-reducing practices (smoking cessation, breastfeeding, and safe sleep [supine sleep, room-sharing not bed-sharing, nonuse of soft bedding or objects]) in a pilot sample of caregivers of OENs.

Refining breast cancer genetic risk and biology through multi-ancestry fine-mapping analyses of 192 risk regions.

Genome-wide association studies have identified approximately 200 genetic risk loci for breast cancer, but the causal variants and target genes are mostly unknown. We sought to fine-map all known breast cancer risk loci using genome-wide association study data from 172,737 female breast cancer cases and 242,009 controls of African, Asian and European ancestry. We identified 332 independent association signals for breast cancer risk, including 131 signals not reported previously, and for 50 of them, we narrowed the credible causal variants down to a single variant.

Prospective pooled analyses of ambient ultraviolet radiation levels and risk of non-Hodgkin lymphoma and multiple myeloma.

Case-control studies of sun exposure and ultraviolet radiation (UVR) have consistently reported inverse associations with non-Hodgkin lymphoma (NHL) risk, but prospective studies have yielded mixed results. Few studies have explored these exposures in relation to multiple myeloma (MM) risk. To further evaluate these associations with NHL and MM risk and identify etiologically relevant exposure timing, we pooled data on 566,693 individuals from 6 United States (U.

Exploring the Perspectives of Older Adults on a Digital Brain Health Platform Using Natural Language Processing: Cohort Study.

Background: Although digital technology represents a growing field aiming to revolutionize early Alzheimer disease risk prediction and monitoring, the perspectives of older adults on an integrated digital brain health platform have not been investigated.

Objective: This study aims to understand the perspectives of older adults on a digital brain health platform by conducting semistructured interviews and analyzing their transcriptions by natural language processing.

Methods: The study included 28 participants from the Boston University Alzheimer's Disease Research Center, all of whom engaged with a digital brain health platform over an initial assessment period of 14 days.

Pathogenic Variants in Cancer Susceptibility Genes Predispose to Ductal Carcinoma In Situ of the Breast.

Purpose: To determine the relationship between germline pathogenic variants (PV) in cancer predisposition genes and the risk of ductal carcinoma in situ (DCIS).

Experimental Design: Germline PV frequencies in breast cancer predisposition genes (ATM, BARD1, BRCA1, BRCA2, CDH1, CHEK2, PALB2, RAD51C, and RAD51D) were compared between DCIS cases and unaffected controls and between DCIS and invasive ductal breast cancer (IDC) cases from a clinical testing cohort (n = 9,887), a population-based cohort (n = 3,876), and the UK Biobank (n = 2,421). The risk of contralateral breast cancer (CBC) for DCIS cases with PV was estimated in the population-based cohort.

Total testosterone, sex hormone-binding globulin, and free testosterone concentrations and risk of primary liver cancer: A prospective analysis of 200,000 men and 180,000 postmenopausal women.

In most countries, males have ~2-3 times higher incidence of primary liver cancer than females. Sex hormones have been hypothesized to contribute to these differences, but the evidence remains unclear. Using data from the UK Biobank, which included ~200,000 males and ~180,000 postmenopausal females who provided blood samples at recruitment, we estimated hazard ratios (HR) and 95% confidence intervals (CI) for a doubling in hormone concentration from multivariable adjusted Cox regression for circulating total testosterone, sex-hormone binding globulin (SHBG), and free testosterone concentrations and risk of primary liver cancer.

Assessment of Wearable Device Adherence for Monitoring Physical Activity in Older Adults: Pilot Cohort Study.

Background: Physical activity has emerged as a modifiable behavioral factor to improve cognitive function. However, research on adherence to remote monitoring of physical activity in older adults is limited.

Objective: This study aimed to assess adherence to remote monitoring of physical activity in older adults within a pilot cohort from objective user data, providing insights for the scalability of such monitoring approaches in larger, more comprehensive future studies.

Clinical, Diagnostic, and Metabolic Characteristics Associated with Nephrolithiasis in the Black Women's Health Study.

Nephrolithiasis (kidney stones) is a frequently occurring urologic condition resulting in significant patient morbidity and healthcare costs. Despite the higher prevalence of metabolic risk factors for nephrolithiasis among Black women, there have been few epidemiologic studies of kidney stones focusing on this group. We describe demographic and health characteristics, diagnostics, and metabolic profiles of US Black women with self-reported kidney stones.

Identifying Proteomic Prognostic Markers for Alzheimer's Disease with Survival Machine Learning: the Framingham Heart Study.

Background: Protein abundance levels, sensitive to both physiological changes and external interventions, are useful for assessing the Alzheimer's disease (AD) risk and treatment efficacy. However, identifying proteomic prognostic markers for AD is challenging by their high dimensionality and inherent correlations.

Methods: Our study analyzed 1128 plasma proteins, measured by the SOMAscan platform, from 858 participants 55 years and older (mean age 63 years, 52.

Liver Cancer: Progress and Priorities.

Liver cancer, the sixth most frequently occurring cancer in the world and the third most common cause of cancer mortality, has wide geographical variation in both incidence and mortality rates. At the end of the 20th century, incidence rates began declining in some high-rate areas and increasing in some lower-rate areas. These trends were undoubtedly driven by the shifting contributions of both well-established and more novel risk factors.

Detection of Mild Cognitive Impairment From Non-Semantic, Acoustic Voice Features: The Framingham Heart Study.

Background: With the aging global population and the rising burden of Alzheimer disease and related dementias (ADRDs), there is a growing focus on identifying mild cognitive impairment (MCI) to enable timely interventions that could potentially slow down the onset of clinical dementia. The production of speech by an individual is a cognitively complex task that engages various cognitive domains. The ease of audio data collection highlights the potential cost-effectiveness and noninvasive nature of using human speech as a tool for cognitive assessment.

Communication Practices for Families With Languages Other Than English in US Neonatal Care Units.

Background And Objectives: The lack of provision of culturally and linguistically appropriate services (CLAS) to families with languages other than English (LOE) is a highly modifiable driver of health care inequities. In a nationally representative sample of level 2 to 4 US NICUs, we examined patterns and predictors of communication practices for families with LOE and ascertained clinical leaders' beliefs about barriers to CLAS provision.

Methods: We surveyed clinical leaders from 500 randomly selected US NICUs.

Lifecourse Growth and Development Determinants of Mammographic Density in Black Women.

Background: High mammographic density is one of the strongest breast cancer risk factors; however, determinants of high mammographic density are understudied in Black women. We assessed growth and development factors across the lifecourse in relation to mammographic density.

Methods: Within the Black Women's Health Study, we used Cumulus software to assess percent mammographic density from digital screening mammograms for 5,905 women ages 40 to 74 years.
