Identifying the barriers and perceptions of non-Hispanic black and Hispanic/Latino persons with uncontrolled type 2 diabetes for participation in a home Telemonitoring feasibility study: a quantitative analysis of those who declined participation, withdrew or were non-adherent

ABSTRACT Objectives: Type 2 Diabetes Mellitus and its complications disproportionately affect non-Hispanic blacks and Hispanic/Latinos more than non-Hispanic whites. These disparities stem from complex interactions between biological, behavioral and socioeconomic factors. In recent years, telemedicine has been used to manage Type 2 Diabetes; however limited recruitment and retention of black and Hispanic/Latino patients into clinical trials exploring the use of telemedicine have necessitated the elucidation of their perceptions regarding participation in such trials. This study investigated patient-reported reasons for declining participation, prematurely terminating participation or demonstrating poor adherence to the study protocol in an ongoing randomized clinical trial, ‘Feasibility of Telehealth Management of Diabetes Mellitus type 2 (T2DM) in Black and Hispanic Minority Patients’. Design: Semi-structured interviews comprised of open-ended questions and prompts were conducted by telephone to gauge patients’ actual and perceived challenges to participating in the trial and using telemedicine to manage their diabetes. Data were collated with that of the original clinical trial and subsequently content analyzed for overarching themes and trends. Results: Eight semi-structured interviews were completed telephonically. Themes that emerged from analysis included disinterest (47%), inconvenience (33%), lack of perceived benefit (13%), lack of awareness of diabetes diagnosis (7%) and perceived lack of ability to fully participate in the study (7%). Conclusion: Adoption of telemedicine to help minority patients manage diabetes holds promise but is limited by patient factors such as disinterest, inconvenience and lack of perceived benefit. Greater awareness and understanding of these issues will be critical as we strive for greater health equity in disparity patients with uncontrolled diabetes.

The effects of psychoeducational interventions on caregivers of children with cancer: A meta-analysis of randomized controlled trials

This meta-analysis aims to evaluate the best available evidence concerning the effects of psychoeducational interventions (PEIs) on the psychosocial and coping outcomes for caregivers of pediatric oncology patients. A literature search was performed using 11 databases, from inception to June 2017. Keywords such as pediatric, caregiver, parents, cancer, and intervention were used. Only randomized controlled trials (RCTs) were included. Studies with full text available online in English and those conducted of caregivers of children diagnosed with any form of cancer were included. Eleven RCTs were included in the analysis. Our meta-analysis revealed that PEIs have small to large effects on three outcomes, including post-traumatic stress symptoms (PTSSs), mood, and problem-solving skills. However, the outcomes from PEI were not superior to the usual standard of care for anxiety, depression, and social support. Our meta-analysis provided moderate evidence that PEI enhances psychological and coping outcomes. Because coping affects both physical and psychological health, health care professionals could consider including coping as a core component in PEI delivered to caregivers of children with cancer.
The Use of Anatomical Dissection Videos in Medical Education

Dissection videos are commonly utilized in gross anatomy courses; however, the actual usage of such videos, as well as the academic impact of student use of these videos, is largely unknown. Understanding how dissection videos impact learning is important in making curricular decisions. In this study, 22 dissection videos were created to review structures identified in laboratory sessions throughout the Organ Systems 1 (OS1), 2 (OS2), and 3 (OS3) courses. Dissection videos were provided to 201 first‐year medical students, and viewing data were recorded. Demographic data for age and gender identity were also collected from students. Overall, there was a significant decrease in total views (P = 0.001), the number of students who pressed play (P < 0.001), and the number of students who viewed ≥ 90% of the total length of videos (P < 0.001) from OS1 to OS3. The total adjusted time spent viewing videos was not significantly different between individual OS courses. There were some instances where significant differences existed in examination performance between those who did and did not view videos, and by time spent viewing videos. There were no significant differences in time spent viewing videos by gender. Together these data suggest that students may utilize dissection videos more at the beginning of a dissection course, although they remain an important resource throughout the year for a subset of students.
Determinants of assessing efficiency within auditory attention networks

Abstract The attention network test (ANT) assesses efficiency across alerting, orienting, and executive components of visual attention. This study examined approaches to assessing auditory attention networks, and performance was compared to the visual ANT. Results showed (1) alerting was sufficiently elicited in a pitch discrimination and sound localization task, although these effects were unrelated, (2) weak orienting of attention was elicited through pitch discrimination, which varied based on ISI and conflict level, but robust orienting of attention was found through sound localization, and (3) executive control was sufficiently assessed in both pitch discrimination and sound localization tasks, but these effects were unrelated. Correlation analysis suggested that, unlike alerting and orienting, sound localization auditory executive control functions tap a shared attention network system. Overall, the results suggest that auditory ANT measures are largely task and modality specific, with sound localization offering potential to assess all three attention networks in a single task.
Therapeutic effect of the epidermal growth factor on diabetic foot ulcer and the underlying mechanisms

The present study aimed to explore the therapeutic effect and underlying mechanism of epidermal growth factor (EGF) on the wound healing of diabetic foot ulcers (DFU). A total of 48 rabbits with DFU were randomly divided into 2 groups, comprising the treatment and control groups. Full-thickness skin (10×10 mm) was excised from the thigh of each rabbit. The wounds in the treatment group were treated with 100 mg/l EGF once a day for 1 month. The control group received no treatment. At 20 days following treatment, new granulation tissues that formed beyond the edge of the wound were collected for subsequent analysis. Tissues from rabbits in the treatment group produced a greater number of fibroblasts, which exhibited a fibroblastic morphology when compared with those in the control group. In the treatment group, a larger number of these fibroblasts were observed as clusters, and there were numerous blood vessels when compared with the control group. The fibroblasts in the control group exhibited an irregular morphology, contained fewer organelles and the surrounding collagenous fibers were sparse. These fibroblasts also demonstrated a disordered arrangement and it was revealed that the wound healed at a slower rate compared with the treatment group. Endogenous EGF mRNA detection revealed that there was a significant difference (P<0.05) in the relative gray value of EGF mRNA between the treatment (103.27±4.27) and control (63.88±4.36) groups. In conclusion, EGF may accelerate the healing of DFU, and exogenous EGF treatment may upregulate the expression of EGF mRNA in newly generated tissues.
Parallel Association Rule Mining System for Continuous Data Streams

In recent times, the data generation and storage modules in several organizations have seen a shift from the centralized approach to a parallel and distributed architecture. Also, the nature of data is changing from the static tables in databases and data warehouses to continuous stream data in data stores used for various technical and business applications. In such times, it is necessary to have data mining systems which accept data generated independently at disparate sites and perform mining at the local sites as well as at the global level at a centralized location. This paper describes a complete system to handle continuous stream data at parallel sites, the memory management involved in the storage of this data and an algorithm specifically designed to perform association rule mining in such an environment.
Human Ultraweak Photon Emission: Key Analytical Aspects, Results and Future Trends – A Review

Abstract Living systems emit what is called ultraweak photon emission (UPE). This visually undetectable phenomenon has only been studied in humans for the last 30 years, finding that UPE is a complex process depending on multitude factors. Considering previous literature, this review discusses the current trends in the analysis of in vivo UPE from human beings. To this aim, Analytical Approaches Employed for UPE Measurement section focuses on the analytical techniques employed (photomultipliers and charged coupled device cameras), summarizing analytical conditions and reporting figures of merit reached to date. Then, Human UPE Depending on External Factors and Human UPE Depending on Internal Factors sections address external and internal factors, which have proved to affect UPE, pointing out the important influence on oxidative processes outside and inside the body, and also highlighting some personal states of the individuals affecting UPE. Last section is devoted to give a general view on the goals and achieved up to date regarding UPE measurement, emphasizing some potential applications as well as recommendations which include: use of UPE spectra information together with UPE intensity, larger populations (≈50–100 subjects), further studies on internal states of individuals, and use of statistical tools.
Evaluating the Use of Nonrandomized Real‐World Data Analyses for Regulatory Decision Making

The analysis of longitudinal healthcare data outside of highly controlled parallel‐group randomized trials, termed real‐world evidence (RWE), has received increasing attention in the medical literature. In this paper, we discuss the potential role of RWE in drug regulation with a focus on the analysis of healthcare databases. We present several cases in which RWE is already used and cases in which RWE could potentially support regulatory decision making. We summarize key issues that investigators and regulators should consider when designing or evaluating such studies, and we propose a structured process for implementing analyses that facilitates regulatory review. We evaluate the empirical evidence base supporting the validity, transparency, and reproducibility of RWE from analysis of healthcare databases and discuss the work that still needs to be done to ensure that such analyses can provide decision‐ready evidence on the effectiveness and safety of treatments.
Evolution of Disease Defense Genes and Their Regulators in Plants

Biotic stresses do damage to the growth and development of plants, and yield losses for some crops. Confronted with microbial infections, plants have evolved multiple defense mechanisms, which play important roles in the never-ending molecular arms race of plant–pathogen interactions. The complicated defense systems include pathogen-associated molecular patterns (PAMP) triggered immunity (PTI), effector triggered immunity (ETI), and the exosome-mediated cross-kingdom RNA interference (CKRI) system. Furthermore, plants have evolved a classical regulation system mediated by miRNAs to regulate these defense genes. Most of the genes/small RNAs or their regulators that involve in the defense pathways can have very rapid evolutionary rates in the longitudinal and horizontal co-evolution with pathogens. According to these internal defense mechanisms, some strategies such as molecular switch for the disease resistance genes, host-induced gene silencing (HIGS), and the new generation of RNA-based fungicides, have been developed to control multiple plant diseases. These broadly applicable new strategies by transgene or spraying ds/sRNA may lead to reduced application of pesticides and improved crop yield.
Effect of Glyceryl Trinitrate on Hemodynamics in Acute Stroke

Background and Purpose— Increased blood pressure (BP), heart rate, and their derivatives (variability, pulse pressure, rate-pressure product) are associated with poor clinical outcome in acute stroke. We assessed the effects of glyceryl trinitrate (GTN) on hemodynamic parameters and these on outcome in participants in the ENOS trial (Efficacy of Nitric Oxide in Stroke). Methods— Four thousand and eleven patients with acute stroke and raised BP were randomized within 48 hours of onset to transdermal GTN or no GTN for 7 days. Peripheral hemodynamics were measured at baseline (3 measures) and daily (2 measures) during treatment. Between-visit BP variability over days 1 to 7 (as SD) was assessed in quintiles. Functional outcome was assessed as modified Rankin Scale and cognition as telephone mini-mental state examination at day 90. Analyses were adjusted for baseline prognostic variables. Data are mean difference or odds ratios with 95% CI. Results— Increased baseline BP (diastolic, variability), heart rate, and rate-pressure product were each associated with unfavorable functional outcome at day 90. Increased between-visit systolic BP variability was associated with an unfavourable shift in modified Rankin Scale (highest quintile adjusted odds ratio, 1.65; 95% CI, 1.37–1.99), worse cognitive scores (telephone mini-mental state examination: highest quintile adjusted mean difference, −2.03; 95% CI, −2.84 to −1.22), and increased odds of death at day 90 (highest quintile adjusted odds ratio, 1.57; 95% CI, 1.12–2.19). GTN lowered BP and rate-pressure product and increased heart rate at day 1 and reduced between-visit systolic BP variability. Conclusions— Increased between-visit BP variability was associated with poor functional and cognitive outcomes and increased death 90 days after acute stroke. In addition to lowering BP and rate-pressure product, GTN reduced between-visit systolic BP variability. Agents that lower BP variability in acute stroke require further study.
Proximal, Distal, and Contralateral Effects of Blood Flow Restriction Training on the Lower Extremities: A Randomized Controlled Trial

Background: Blood flow restriction (BFR) training involves low-weight exercises performed under vascular occlusion via an inflatable cuff. For patients who cannot tolerate high-load exercises, BFR training reportedly provides the benefits of high-load regimens, with the advantage of less tissue and joint stress. Hypothesis: Low-load BFR training is safe and efficacious for strengthening muscle groups proximal, distal, and contralateral to tourniquet placement in the lower extremities. Study Design: Randomized controlled trial. Level of Evidence: Level 1. Methods: This was a randomized controlled trial of healthy participants completing a standardized 6-week course of BFR training. Patients were randomized to BFR training on 1 extremity or to a control group. Patients were excluded for cardiac, pulmonary, or hematologic disease; pregnancy; or previous surgery in the extremity. Data collected at baseline and completion included limb circumferences and strength testing. Results: The protocol was completed by 26 patients, providing 16 BFR and 10 control patients (mean patient age, 27 years; 62% female). A statistically greater increase in strength was seen proximal and distal to the BFR tourniquet when compared with both the nontourniquet extremity and the control group (P < 0.05). Approximately twice the improvement was seen in the BFR group compared with controls. Isokinetic testing showed greater increases in knee extension peak torque (3% vs 11%), total work (6% vs 15%), and average power (4% vs 12%) for the BFR group (P < 0.04). Limb circumference significantly increased in both the thigh (0.8% vs 3.5%) and the leg (0.4% vs 2.8%) compared with the control group (P < 0.01). Additionally, a significant increase occurred in thigh girth (0.8% vs 2.3%) and knee extension strength (3% vs 8%) in the nontourniquet BFR extremity compared with the control group (P < 0.05). There were no reported adverse events. Conclusion: Low-load BFR training led to a greater increase in muscle strength and limb circumference. BFR training had similar strengthening effects on both proximal and distal muscle groups. Gains in the contralateral extremity may corroborate a systemic or crossover effect. Clinical Relevance: BFR training strengthens muscle groups proximal, distal, and contralateral to cuff placement. Patients undergoing therapy for various orthopaedic conditions may benefit from low-load BFR training with the advantage of less tissue stress.
Dynamic changes in seating pressure gradient in wheelchair users with spinal cord injury

ABSTRACT Pressure ulcer interventions are commonly assessed with measures of seating interface pressure, such as peak pressure gradients (PPGs). Decreases in PPG magnitudes may reduce pressure ulcer risk by decreasing tissue deformation and increasing tissue perfusion of at-risk weight-bearing tissues. Changes in PPG directions, which have previously been overlooked in the seating pressure literature, may provide a transient increase in blood flow to at-risk tissues, even if the PPG magnitude and location remain the same. The purpose of this study was to assess both PPG components in response to combinations of wheelchair tilt and recline angles. Thirteen power wheelchair users were recruited into the study. Six combinations of wheelchair tilt (15°, 25°, and 35°) and recline (10° and 30°) were tested in random order. Each combination was tested with 5-min upright sitting, 5-min tilt and recline, and 5-min maximal pressure relief recovery. Changes in PPG magnitudes and PPG directions under the left ischial tuberosity were computed for the six angle combinations. The findings in this study suggested that when combining wheelchair tilt and recline, the recline function may be particularly useful in reducing PPG magnitudes, while the tilt function may be particularly useful in manipulating PPG directions.
Evaluating safety and cost‐effectiveness of platelets stored in additive solution (PAS‐F) as a hemolysis risk mitigation strategy

Platelet inventory constraints can result in minor ABO incompatibility and possible hemolysis. The aims of this study were to determine the reduction of isoagglutinin in titers of platelets stored in additive solution (PAS) and compare its safety, efficiency, and cost‐effectiveness with full‐volume and plasma‐reduced platelets.
Impact of vaginal dehydroepiandosterone (DHEA) on vaginal symptoms in female cancer survivors: Trial N10C1 (Alliance).

9507 Background: Impaired sexual satisfaction is a prevalent and distressing issue for female cancer survivors. The aim of this study was to evaluate the impact of vaginal DHEA on vaginal atrophy symptoms and sexual function. Methods: A controlled, randomized trial evaluating 3.25 versus 6.5 mg of DHEA vaginally was conducted. Postmenopausal women with previous breast or gynecologic cancer were eligible if they reported ≥ moderate vaginal dryness or pain. DHEA was compounded in a bioadhesive vaginal moisturizer. Women inserted the bioadhesive moisturizer with or without DHEA using a pre-filled syringe daily x 12 weeks before going to sleep, after any sexual activity. The most bothersome vaginal symptom (dryness or pain) was evaluated with a single item Likert scale, and sexual function with the Female Sexual Function Index (FSFI). Side effects were graded by providers using the Common Terminology Criteria for Adverse Events (CTCAE) and self-report. Laboratory tests to assess systemic absorption were done.
Expanding the miRNA Repertoire in Atlantic Salmon; Discovery of IsomiRs and miRNAs Highly Expressed in Different Tissues and Developmental Stages

MicroRNAs (miRNAs) are important post-transcriptional gene expression regulators. Here, 448 different miRNA genes, including 17 novel miRNAs, encoding for 589 mature Atlantic salmon miRNAs were identified after sequencing 111 samples (fry, pathogen challenged fry, various developmental and adult tissues). This increased the reference miRNAome with almost one hundred genes. Prior to isomiR characterization (mature miRNA variants), the proportion of erroneous sequence variants (ESVs) arising in the analysis pipeline was assessed. The ESVs were biased towards 5’ and 3’ end of reads in unexpectedly high proportions indicating that measurements of ESVs rather than Phred score should be used to avoid misinterpreting ESVs as isomiRs. Forty-three isomiRs were subsequently discovered. The biological effect of the isomiRs measured as increases in target diversity was small (<3%). Five miRNA genes showed allelic variation that had a large impact on target gene diversity if present in the seed. Twenty-one miRNAs were ubiquitously expressed while 31 miRNAs showed predominant expression in one or few tissues, indicating housekeeping or tissue specific functions, respectively. The miR-10 family, known to target Hox genes, were highly expressed in the developmental stages. The proportion of miR-430 family members, participating in maternal RNA clearance, was high at the earliest developmental stage.
Joint Estimation of DOA and Frequency of Multiple Sources with Orthogonal Coprime Arrays

A two-stage method is proposed to jointly estimate the direction-of-arrival (DOA) and carrier frequency (CF) of multiple sources, by using two orthogonal coprime arrays (CPAs). The DOAs of CF-known sources are estimated first by applying a spatial smoothing MUSIC algorithm. The contribution of these source signals is then removed from the originally received signal by applying an orthogonal complement projector. Next, a joint-ESPRIT algorithm is applied to estimate the DOAs and CFs of the remaining CF-unknown sources. With two orthogonal CPA(5, 6), the RMSE of DOA and CF of applying the proposed method to 30 sources, 13 of which have unknown CF, is less than 1% at SNR >5 dB.
