Predictors of racial differences in weight loss: the PROPEL trial.

Objective: Studies have consistently shown that African American individuals lose less weight in response to behavioral interventions, but the mechanisms leading to this result have been understudied.

Methods: Data were derived from the PROmoting Successful Weight Loss in Primary CarE in Louisiana (PROPEL) study, which was a cluster-randomized, two-arm trial conducted in primary care clinics. In the PROPEL trial, African American individuals lost less weight compared with patients who belonged to other racial groups after 24 months.

Initial weight loss and early intervention adherence predict long-term weight loss during the Promoting Successful Weight Loss in Primary Care in Louisiana lifestyle intervention.

Methods: Data from the intervention group (n = 452; 88% women; 74% Black; BMI 37.3 kg/m [SD: 4.

Dietary intake during a pragmatic cluster-randomized weight loss trial in an underserved population in primary care.

Background: Currently there are limited data as to whether dietary intake can be improved during pragmatic weight loss interventions in primary care in underserved individuals.

Methods: Patients with obesity were recruited into the PROPEL trial, which randomized 18 clinics to either an intensive lifestyle intervention (ILI) or usual care (UC). At baseline and months 6, 12, and 24, fruit and vegetable (F/V) intake and fat intake was determined.

Clinical trial participation among underserved communities: Insights from the Louisiana Community Engagement Alliance.

Background: Diverse, equitable and inclusive participation in clinical research is needed to ensure evidence-based clinical practice and lessen disparities in health outcomes. Yet, clinical trial participation remains critically low in minoritized communities, particularly among Blacks. The Louisiana Community Engagement Alliance against COVID-19 Disparities (LA-CEAL) was launched in response to the disproportionate impact of COVID-19 on Black Louisianans to understand community barriers and preferences and increase inclusive participation in research.

Impact of a Community-Based Weight Management Program in a North Carolina Health Care System.

Background And Objectives: Current strategies for obesity management in primary care leave many patients inadequately treated or unable to access treatment entirely. We aimed to evaluate a comprehensive, primary care clinic-based weight management program's clinical effectiveness in a community practice setting.  Methods:  This was an 18-month pre/postintervention study.

Using the social vulnerability index to assess COVID-19 vaccine uptake in Louisiana.

Using data from the Louisiana Department of Public Health, we explored the spatial relationships between the Social Vulnerability Index (SVI) and COVID-19-related vaccination and mortality rates. Publicly available COVID-19 vaccination and mortality data accrued from December 2020 to October 2021 was downloaded from the Louisiana Department of Health website and merged with the SVI data; geospatial analysis was then performed to identify the spatial association between the SVI and vaccine uptake and mortality rate. Bivariate Moran's I analysis revealed significant clustering of high SVI ranking with low COVID-19 vaccination rates (1.

Design: Participants were recruited from ongoing NIH studies to complete a phone interview and online survey to test candidate items.

Long-term Effects of Remote Patient Monitoring in Patients Living with Diabetes: A Retrospective Look at Participants of the Mississippi Diabetes Telehealth Network Study.

Introduction: Remote patient monitoring (RPM) has demonstrated value as a tool to aid patients in management of their chronic illness in the home. Although the Mississippi Diabetes Telehealth Network Study (MSDTNS) was successful in reducing HbgA1c levels for patients participating in RPM in the Mississippi Delta, the long-term effect of RPM on patients and how to support patients to maintain the treatment effect after discharge remain unclear.

Objective: This study evaluated the long-term effectiveness of an RPM program after the intervention was withdrawn.

COVID-19 Concerns, Vaccine Acceptance and Trusted Sources of Information among Patients Cared for in a Safety-Net Health System.

We examined COVID-19 concerns, vaccine acceptance, and trusted sources of information among patients in a safety-net health system in Louisiana. The participants were surveyed via structured telephone interviews over nine months in 2021. Of 204 adult participants, 65% were female, 52% were Black, 44.

Algorithm development for individualized precision feeding of supplemental top dresses to influence feed efficiency of dairy cattle.

Individualized, precision feeding of dairy cattle may contribute to profitable and sustainable dairy production. Feeding strategies targeted at optimizing efficiency of individual cows, rather than groups of animals with similar characteristics, is a logical goal of individualized precision feeding. However, algorithms designed to make feeding recommendations for specific animals are scarce.

Cell twisting during desiccation reveals axial asymmetry in wall organization.

Plant cell size and shape are tuned to their function and specified primarily by cellulose microfibril (CMF) patterning of the cell wall. Arabidopsis thaliana leaf trichomes are unicellular structures that act as a physical defense to deter insect feeding. This highly polarized cell type employs a strongly anisotropic cellulose wall to extend and taper, generating sharply pointed branches.

COVID-19 Knowledge, Beliefs, and Behavior Among Patients in a Safety-Net Health System.

Examine COVID-19 knowledge, concerns, behaviors, stress, and sources of information among patients in a safety-net health system in Louisiana. Research assistants surveyed participants via structured telephone interviews from April to October 2020. The data presented in this study were obtained in the pre-vaccine availability period.

Short-Term Adaptation of Dairy Cattle Production Parameters to Individualized Changes in Dietary Top Dress.

Immediate and short-term changes in diet composition can support individualized, real-time interventions in precision dairy production systems, and might increase feed efficiency (FE) of dairy cattle in the short-term. The objective of this study was to determine immediate and short-term effects of changes in diet composition on production parameters of dairy cattle fed varying amounts of top dressed commodities. A 4 × 4 replicated Latin square design was used to evaluate responses of twenty-four Holstein cows fed either no top dress (Control) or increasing amounts of: corn grain (CG), soybean meal (SBM), or chopped mixed grass hay (GH) top dressed on a total mixed ration (TMR) over four, 9-day periods.

Design of a randomized controlled trial to assess the comparative effectiveness of a multifaceted intervention to improve three-year adherence to colorectal cancer screening among patients cared for in rural community health centers.

Colorectal cancer (CRC) screening has been shown to decrease CRC mortality, yet significant disparities persist among those living in rural areas, from minority backgrounds, and those having low income. The purpose of this two-arm randomized controlled trial is to test the effectiveness and fidelity of a stepped care (increasing intensity as needed) approach to promoting 3-year adherence to CRC screening via fecal immunochemical testing (FIT) or colonoscopy in rural community clinics serving high rates of low-income and minority patients. We hypothesize that, compared to enhanced usual care (EUC), patients receiving the multifaceted CRC screening intervention will demonstrate higher rates of CRC screening completion over 3 years.

Patients completed a structured interview including a health literacy assessment, a Brief Medication Questionnaire, two single-item self-report adherence questions, and the Medications Adherence Reasons Scale. Of the 86 participants, 88.

Plenty of Room at the Top: A Multi-Scale Understanding of nm-Resolution Polymer Patterning on 2D Materials.

Lamellar phases of alkyldiacetylenes in which the alkyl chains lie parallel to the substrate represent a straightforward means for scalable 1-nm-resolution interfacial patterning. This capability has the potential for substantial impacts in nanoscale electronics, energy conversion, and biomaterials design. Polymerization is required to set the 1-nm functional patterns embedded in the monolayer, making it important to understand structure-function relationships for these on-surface reactions.

Oleylamine Impurities Regulate Temperature-Dependent Hierarchical Assembly of Ultranarrow Gold Nanowires on Biotemplated Interfaces.

Nanocrystals are often synthesized using technical grade reagents such as oleylamine (OLAm), which contains a blend of octadeceneamine with -unsaturated and saturated amines. Here, we show that gold nanowires (AuNWs) synthesized with OLAm ligands undergo thermal transitions in interfacial assembly (ribbon . nematic); transition temperatures vary widely with the batch of OLAm used for synthesis.

Examining nonprescription syringe sales in Massachusetts and Rhode Island community pharmacies.

Background: The role pharmacies play in addressing the opioid crisis and drug-related risks such as injection drug use is evolving. Estimating the prevalence of injection drug use at the community level is challenging because of the stigma of drug use. Many community pharmacies sell nonprescription sterile syringes; thus, pharmacy-level sales of injection equipment may be an indicator of drug-related harms and unmet needs of high-risk populations.

Susceptibility of widely diverse influenza a viruses to PB2 polymerase inhibitor pimodivir.

Pimodivir exerts an antiviral effect on the early stages of influenza A virus replication by inhibiting the cap-binding function of polymerase basic protein 2 (PB2). In this study, we used a combination of sequence analysis and phenotypic methods to evaluate pimodivir susceptibility of influenza A viruses collected from humans and other hosts. Screening PB2 sequences for substitutions previously associated with reduced pimodivir susceptibility revealed a very low frequency among seasonal viruses circulating in the U.

Effects of a 2-Year Primary Care Lifestyle Intervention on Cardiometabolic Risk Factors: A Cluster-Randomized Trial.

Background: Intensive lifestyle interventions (ILIs) are the first-line approach to effectively treat obesity and manage associated cardiometabolic risk factors. Because few people have access to ILIs in academic health centers, primary care must implement similar approaches for a meaningful effect on obesity and cardiometabolic disease prevalence. To date, however, effective lifestyle-based obesity treatment in primary care is limited.
