Design: Cross-sectional study.

Building a Community Partnership for the Development of Health Ministries Within the African American Community: The Triad Pastors Network.

African Americans continue to have worse health outcomes despite attempts to reduce health disparities. This is due, in part, to inadequate access to healthcare, but also to the health care and medical mistrust experienced by communities of color. Churches and worship centers have historically served as cultural centers of trusted resources for educational, financial, and health information within African American communities and a growing number of collaborations have developed between academic institutions and community/faith entities.

Involuntary sedation of patients in the emergency department for mental health: A retrospective cohort study.

Background: Involuntary sedation of agitated mental health patients in the Emergency Department (ED) is standard practice to obtain accurate medical assessments and maintain safety. However, the rate of this practice and what factors are associated with the use of involuntary sedation is unknown. The purpose of this study was to obtain baseline data on involuntary sedation in our EDs.

Interlaboratory evaluation of quality control methods for circulating cell-free DNA extraction.

Analysis of circulating cell-free DNA (ccfDNA) isolated from liquid biopsies is rapidly being implemented into clinical practice. However, diagnostic accuracy is significantly impacted by sample quality and standardised approaches for assessing the quality of ccfDNA are not yet established. In this study we evaluated the application of nucleic acid "spike-in" control materials to aid quality control (QC) and standardisation of cfDNA isolation for use in in vitro diagnostic assays.

Gender, Age and COVID-19 Vaccination Status in African American Adult Faith-Based Congregants in the Southeastern United States.

Objectives: The COVID-19 pandemic has revealed significant differences in COVID-19 vaccination rates, with African Americans reporting lower rates compared to other racial and ethnic groups. The purpose of these analyses was to assess whether COVID-19 vaccination status differed according to age in a sample of 1,240 African American adult congregants of faith-based organizations ages 18 years or older, and to examine whether this association was moderated by gender.

Design: We developed and administered a 75-item cross-sectional survey, the Triad Pastor's Network COVID-19 and COVID-19 Vaccination survey, to assess experiences and perceptions regarding the COVID-19 virus and vaccines.

Isolation of new Paraburkholderia strains for polyhydroxybutyrate production.

Polyhydroxyalkanoates (PHAs) are bioplastics that can serve as substitutes for petroleum-based plastics with the advantages of being biodegradable, biocompatible, and biobased. The microbial production of polyhydroxyalkanoates is generally conducted in the presence of sugar mixes rich in monosaccharides. In this study, molecular and cultural approaches based on forest soils enriched with hydrocarbon complexes led to the identification and isolation of microbial strains affiliated with Paraburkholderia sp.

Assessing the Role of Trust in Public Health Agencies and COVID-19 Vaccination Status Among a Community Sample of African Americans in North Carolina.

Background: Mistrust of the government and medical establishments are prominent reasons for vaccine hesitancy among African Americans (AAs). As COVID-19 research evolves in real time with some uncertainties remaining, AA communities may be less trusting of public health agencies. The purpose of these analyses was to assess the association between trust in public health agencies that recommend the COVID-19 vaccination and COVID-19 vaccination status among AAs in North Carolina.

Inducing Ulnar Nerve Function while Eliminating Claw Hand and Reducing Chronic Neuropathic Pain.

Ulnar nerve injury induces chronic neuropathic pain and is frequently devastating due to loss of cupping the hand around objects (finger clawing) and diminished grip strength. There is little chance of restoring good function, eliminating finger clawing, or reducing the pain. A novel technique was tested for its efficacy in promoting ulnar nerve function and reducing finger clawing and chronic neuropathic pain.

Use of coaching and technology to improve blood pressure control in Black women with hypertension: Pilot randomized controlled trial study.

Hypertension is the main cause of cardiovascular disease, especially in women. Black women (58%) are affected by higher rates of hypertension than other racial/ethnic groups contributing to increased cardio-metabolic disorders. To decrease blood pressure (BP) in this population, a pilot randomized controlled trial was conducted to examine the effects of Interactive Technology Enhanced Coaching (ITEC) versus Interactive Technology (IT) alone in achieving BP control, adherence to antihypertensive medication, and adherence to lifestyle modifications among Black women diagnosed with and receiving medication for their hypertension.

A standardised methodology for the extraction and quantification of cell-free DNA in cerebrospinal fluid and application to evaluation of Alzheimer's disease and brain cancers.

Cerebrospinal fluid (CSF) is a source of diagnostic biomarkers for a range of neurological conditions. Cell-free DNA (cfDNA) is detected in CSF and differences in the concentration of cell-free mitochondrial DNA have been reported in studies of neurodegenerative disorders including Alzheimer's disease (AD). However, the influence of pre-analytical steps has not been investigated for cfDNA in CSF and there is no standardised approach for quantification of total cfDNA (copies of nuclear genome or mitochondria-derived gene targets).

Evaluating the effectiveness of abbreviated breast MRI (abMRI) interpretation training for mammogram readers: a multi-centre study assessing diagnostic performance, using an enriched dataset.

Background: Abbreviated breast MRI (abMRI) is being introduced in breast screening trials and clinical practice, particularly for women with dense breasts. Upscaling abMRI provision requires the workforce of mammogram readers to learn to effectively interpret abMRI. The purpose of this study was to examine the diagnostic accuracy of mammogram readers to interpret abMRI after a single day of standardised small-group training and to compare diagnostic performance of mammogram readers experienced in full-protocol breast MRI (fpMRI) interpretation (Group 1) with that of those without fpMRI interpretation experience (Group 2).

Prospects for Improving the Extent of Recovery following Peripheral Nerve Trauma: A Review.

Restoring function to damaged peripheral nerves with a gap remains challenging, with <50% of patients who undergo nerve repair surgery recovering function. Further, despite enormous efforts to improve existing techniques and develop new ones, the percentage of patients who recover function and their extent of recovery has not increased in almost 70 years. Thus, although sensory nerve grafts remain the clinical "gold standard" technique for attempting to restore function to nerves with a gap, they have significant limitations.

NoiseCapture smartphone application as pedagogical support for education and public awareness.

Teaching science subjects such as acoustics to youth or the general public can be facilitated by illustrating physical phenomena or scientific issues using fun experiences. A few years ago, our team developed a smartphone application named NoiseCapture with the aim of offering to anyone the opportunity to measure their sound environment and to share their geolocated measurements with the community in order to build a collective noise map. Since then, NoiseCapture team members have experimented with numerous interventions in schools or scientific events for the general public based on the app to explain not only societal and environmental issues related to noise but also to teach acoustic notions and to address technical and scientific topics associated with sound measurement.

Applicability of Control Materials To Support Gene Promoter Characterization and Expression in Engineered Cells Using Digital PCR.

The use of standardized components and processes in engineering underpins the design-build-test model, and the engineering of biological systems is no different. Substantial efforts to standardize both the components and the methods to validate the engineered biological systems is ongoing. This study has developed a panel of control materials encoding the commonly used reporter genes GFP and RFP as DNA or RNA molecules.

Consensus guidelines for the validation of qRT-PCR assays in clinical research by the CardioRNA consortium.

Despite promising findings, quantitative PCR (qPCR)-based tests for RNA quantification have experienced serious limitations in their clinical application. The noticeable lack of technical standardization remains a huge obstacle in the translation of qPCR-based tests. The incorporation of qPCR-based tests into the clinic will benefit from guidelines for clinical research assay validation.

Vessel diameter and close surveillance helps predict early patency in native arteriovenous fistulas.

Introduction: Arteriovenous fistulas are the preferred method of vascular access for haemodialysis. Data suggests patency rates can be low and may be related to vessel diameters prior to creation. We use specific size criteria for fistula selection.

The Dangers of Using Cq to Quantify Nucleic Acid in Biological Samples: A Lesson From COVID-19.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA quantities, measured by reverse transcription quantitative PCR (RT-qPCR), have been proposed to stratify clinical risk or determine analytical performance targets. We investigated reproducibility and how setting diagnostic cutoffs altered the clinical sensitivity of coronavirus disease 2019 (COVID-19) testing.

Methods: Quantitative SARS-CoV-2 RNA distributions [quantification cycle (Cq) and copies/mL] from more than 6000 patients from 3 clinical laboratories in United Kingdom, Belgium, and the Republic of Korea were analyzed.

Functional Recovery following Repair of Long Nerve Gaps in Senior Patient 2.6 Years Posttrauma.

Sensory nerve grafts are the clinical "gold standard" for repairing peripheral nerve gaps. However, reliable good-to-excellent recovery develops only for gaps less than 3-5 cm, repairs performed less than 3-5 months posttrauma, and patients aged less than 20-25 years. As the value of any variable increases, the extent of recovery decreases precipitously, and if the values of any two or all increase, there is little to no recovery.

Mean absorption estimation from room impulse responses using virtually supervised learning.

In the context of building acoustics and the acoustic diagnosis of an existing room, it introduces and investigates a new approach to estimate the mean absorption coefficients solely from a room impulse response (RIR). This inverse problem is tackled via virtually supervised learning, namely, the RIR-to-absorption mapping is implicitly learned by regression on a simulated dataset using artificial neural networks. Simple models based on well-understood architectures are the focus of this work.

Inhomogeneous diffusion process in elongated rooms: An interpretation based on the dynamics of sound particles.

Previous studies showed that the reverberant field in elongated rooms is governed by non-homogeneous diffusion. The objective of this study is to physically interpret this phenomenon by considering the dynamics of the sound particles. Starting from the original diffusion theory, a quantity that can be interpreted as a "local" mean free path has been proposed and computed from the paths of the propagating particles.
