OBJECTIVES: Despite significant declines in cigarette smoking during the past decade, other tobacco products gained popularity among middle and high school students. This study examined temporal trends in exclusive and concurrent use of tobacco products among middle and high school students in the United States from 2011 through 2020. METHODS: We used multiple annual datasets from the National Youth Tobacco Survey from 2011 through 2020 (N = 193 350) to examine trends of current (past 30 days) exclusive, dual, and poly use of tobacco products (ie, cigarettes, electronic cigarettes [e-cigarettes], cigars, hookahs, and smokeless tobacco)...

Currently, the debate surrounding the regulation of e-cigarettes focuses mainly on the size of e-cigarettes' potentially beneficial effects (i.e., adult cessation) versus their unwarranted effects (i.e., initiation among tobacco-naïve adolescents). Therefore, we investigated the relative scale of e-cigarette use transitions in the United States. We reported cross-sectional weighted prevalence estimates of past-month e-cigarette use by ever cigarette use from Waves 1-4 of the Population Assessment of Tobacco and Health study (2013-2018) among youth (12-17 years) and adults (≥ 18 years)...

AIMS: To compare brief advice (BA), motivational interviewing (MI), rate reduction (RR), and combined MI and RR (MI + RR) to promote smoking cessation in smokers not ready to quit. DESIGN: Randomized controlled trial with four parallel groups of smoking cessation intervention. Participants were randomly assigned 1:2:2:2 to receive one of the following interventions: BA (n = 128), MI (n = 258), RR (n = 257), and MI + RR (n = 260). SETTING: The United States...

BACKGROUND: Maternal pre-pregnancy body mass index (BMI) is strongly associated with infant birthweight and the risk differs in pregnancies complicated by gestational diabetes (GDM). OBJECTIVES: To examine the risk of large for gestational age (LGA) (≥97th percentile) singleton births at early term, full term and late term in relation to maternal pre-pregnancy BMI status mediated through GDM. METHODS: We analysed data from the 2018 U.S. National Vital Statistics Natality File restricted to singleton term births (N = 3,229,783)...

OBJECTIVES: To assess the outcomes following transcatheter edge-to-edge mitral valve repair (TMVr) in patients with chronic kidney disease (CKD). BACKGROUND: Percutaneous TMVr is beneficial in high surgical risk patients with severe mitral regurgitation (MR). However, those with CKD are not well studied. METHODS: Utilizing the International Classification of Disease (ninth and tenth revision, clinical modification codes) and the Nationwide Inpatient Sample database, we identified 9,228 patients who underwent TMVr during 2010-2016, including those with no or mild CKD (group 1, n = 6,654 [72...

This study examined associations between physical activity frequency and self-efficacy for exercise (SEE) among Marshallese adults in the United States. Data were collected from overweight and obese Marshallese participants (N = 378) enrolled in a Diabetes Prevention Program trial. Logistic and ordinal logistic regressions were employed to examine associations between physical activity and SEE, adjusting for covariates. SEE was significantly associated with engaging in sufficient total physical activity [odds ratio (OR) = 1...

BACKGROUND: The Hispanic/Latinx population constitutes the fastest growing ethnic/racial minority group in the United States (U.S.). Compared to their non-Hispanic/Latinx White counterparts, Hispanic/Latinx youth experience more depression and anxiety, and have more unmet mental health needs (88% vs 76%). Emerging research supports the psychological and physical benefits of mind-body awareness training to enhance well-being and mental health, but almost no studies have recruited ethnic/racial minority samples...

Purpose: The purpose of this ecological study was to understand the impact of the density of African American (AA) communities on coronavirus disease 2019 (COVID-19) prevalence and death rate within the three most populous counties in each U.S. state and territory ( n =152). Methods: An ecological design was employed for the study. The top three most populous counties of each U.S. state and territory were included in analyses for a final sample size of n =152 counties. Confirmed COVID-19 cases and deaths that were accumulated between January 22, 2020 and April 12, 2020 in each of the three most populous counties in each U...

OBJECTIVE: Identifying the factors associated with nicotine dependence (ND) is essential to prevent initiation and continued use, and to promote cessation among youth. This study aims to document the predictors of the appearance of initial ND symptoms and full ND syndrome among adolescent waterpipe (WP) and cigarette smokers. METHODS: A 6-year longitudinal study was conducted among 8th and 9th graders from 38 schools in Lebanon. The analysis sample included exclusive-WP (n = 228) and exclusive-cigarette smokers (n = 139)...

OBJECTIVE: We examined barriers to accessing medical care for migrant US-residing Marshallese Islanders. METHODS: Cross-sectional analyses were conducted to identify potential inequities. Surveys from largely migrant diabetic Marshallese Islanders (n = 255) were compared with nationally representative data. Two major outcomes were assessed including 1-whether or not one reported having forgone medical care in the past year because of cost-and 2-whether or not one reported not having a usual source of care...

OBJECTIVE: This study aimed to (1) examine respective associations of acculturation orientations (e.g., U.S. orientation and Hispanic orientation) and domains (e.g., social groundedness and role repertoire) of bicultural self-efficacy, the perceived confidence to function effectively within the receiving culture and the heritage culture, with alcohol use severity among Hispanic emerging adults. This study also aimed to (2) examine potential moderating factors of respective associations among acculturation orientations and bicultural self-efficacy with alcohol use severity...

INTRODUCTION: Although a number of contraception methods exist, long-acting reversible contraceptives have been recommended for female adolescents owing to their low failure rates. However, concern exists that the increasing use of long-acting reversible contraceptive among female adolescents may have unintended consequences of decreasing condom use for the prevention of sexually transmitted infections. Despite this concern, few studies have directly explored the relationship between the use of long-acting reversible contraceptive versus other forms of contraception and diagnosis of sexually transmitted infections in female adolescents...

BACKGROUND AND OBJECTIVES: Substance use in community college students has been explored in only a handful of studies. Differences in population characteristics and substance use between 2- and 4-year students suggest that different factors may promote and thwart this behavior. Cumulative risk is a parsimonious methodology that provides better model stability and more statistical power, yet it has only been recently used in substance use research. The aim of this study is to investigate multiple aspects of substance use risk in a population in need of substance use prevention and intervention services...

This study reveals that it is possible to secrete truncated versions of outer membrane cytochromes into the culture supernatant and that these proteins can provide a basis for the export of heterologously produced proteins. Different soluble and truncated versions of the outer membrane cytochrome MtrF were analyzed for their suitability to be secreted. A protein version with a very short truncation of the N-terminus to remove the recognition sequence for the addition of a lipid anchor is secreted efficiently to the culture supernatant, and moreover this protein could be further truncated by a deletion of 160 amino acid and still is detectable in the supernatant...

AIMS: A randomized control trial (RCT) of diabetes self-management education (DSME), undertaken by a community-based participatory research (CBPR) partnership between the University of Arkansas for Medical Sciences (UAMS) and the Marshallese community in Arkansas. The RCT examined the effect of hours of intervention exposure, with the hypothesis that increased exposure is one reason the Adapted-Family DSME was found to be more effective than the Standard DSME. METHODS: Some 221 Marshallese with type 2 diabetes were randomized to an Adapted-Family DSME group (in-home setting) (n = 110) or a Standard DMSE group (community setting) (n = 111)...

Research indicates that increased cumulative exposure (duration of administration and strength of dose) is associated with long-term opioid use. Because dentists represent some of the highest opioid prescribing medical professionals in the US, dental practices offer a critical site for intervention. The current study used a randomized clinical trial design to examine the efficacy of an opioid misuse prevention program (OMPP), presented as a brief intervention immediately prior to dental extraction surgery. The OMPP provided educational counseling about risks and appropriate use of opioid medication, as well as 28 tablets of ibuprofen (200 mg) and 28 tablets of acetaminophen (500 mg) for weaning off opioid medication...

BACKGROUND: Flavoured tobacco is one of the major factors behind the popularity of waterpipe (WP) smoking in the USA and internationally. The current study examined the impact of flavour manipulation on satisfaction, puff topography and toxicant exposure among high-frequency and low-frequency WP users. METHOD: This cross-over study was conducted among 144 current (past month) WP smokers reporting WP smoking less than once a week (low-frequency users; n=69) or at least once a week (high-frequency users; n=75) in the past 6 months...

Objective: Examine cross-sectional associations between body mass index (BMI) and related health behaviors, barriers and facilitators to health care, and perceived health status among a sample of U.S. Marshallese adults with Type 2 diabetes and evaluate associations of interest between participants and their family members. Design: Cross-sectional baseline data were analyzed from participants in a diabetes self-management education intervention trial. Setting: Data collection took place in home or community settings through a community-academic partnership in Arkansas...

OBJECTIVE: Marshallese adults experience high rates of type 2 diabetes. Previous diabetes self-management education (DSME) interventions among Marshallese were unsuccessful. This study compared the extent to which two DSME interventions improved glycemic control, measured on the basis of change in glycated hemoglobin (HbA1c ). RESEARCH DESIGN AND METHODS: A two-arm randomized controlled trial compared a standard-model DSME (standard DSME) with a culturally adapted family-model DSME (adapted DSME)...

PURPOSE: Tobacco use in cancer survivors remains a significant problem, however, the use of non-cigarette tobacco products (NCTPs) in this population is less understood. This study examined prevalence and correlates of tobacco use among cancer survivors who were never, current, and former cigarette users. Tobacco-related behaviors and quitting attitudes were compared between survivors dually using cigarettes and electronic cigarettes (ECs) and cigarette-only users. METHODS: In this cross-sectional study, patients at Mid-South cancer centers (n = 629; 50...
