Reducing Cardiovascular Disparities Through Community-Engaged Implementation Research: A National Heart, Lung, and Blood Institute Workshop Report

Cardiovascular disparities remain pervasive in the United States. Unequal disease burden is evident among population groups based on sex, race, ethnicity, socioeconomic status, educational attainment, nativity, or geography. Despite the significant declines in cardiovascular disease mortality rates in all demographic groups during the last 50 years, large disparities remain by sex, race, ethnicity, and geography. Recent data from modeling studies, linked micromap plots, and small-area analyses also demonstrate prominent variation in cardiovascular disease mortality rates across states and counties, with an especially high disease burden in the southeastern United States and Appalachia. Despite these continued disparities, few large-scale intervention studies have been conducted in these high-burden populations to examine the feasibility of reducing or eliminating cardiovascular disparities. To address this challenge, on June 22 and 23, 2017, the National Heart, Lung, and Blood Institute convened experts from a broad range of biomedical, behavioral, environmental, implementation, and social science backgrounds to summarize the current state of knowledge of cardiovascular disease disparities and propose intervention strategies aligned with the National Heart, Lung, and Blood Institute mission. This report presents the themes, challenges, opportunities, available resources, and recommended actions discussed at the workshop.
A “congenitally corrected” variant of Ebstein’s anomaly

Abstract Ebstein’s anomaly is a rare CHD that is characterised by caudal displacement of the functional tricuspid annulus and a dysfunctional tricuspid valve owing to a failure of proper leaflet coaptation. We present a balanced variant of Ebstein’s anomaly, in which the overgrowth of the septal leaflet had allowed proper coaptation of the tricuspid leaflets, thus preserving the valve function.
Neuroglial alterations in the zebrafish brain exposed to cadmium chloride

Cadmium is an extremely toxic heavy metal that widely occurs in industrial workplaces with various hazardous effects on brain functions. The cytotoxic effects of cadmium chloride (CdCl2) on the neuroglial components of the zebrafish brain were analysed by detecting the glial fibrillary acidic protein (GFAP) expression and the mRNA levels of myelin genes mbp, mpz and plp1 in adult specimens exposed to cadmium for 2, 7 and 16 days. A significant decrease in the GFAP protein by Western blotting experiments was observed after 2 days of treatment, reaching 55% after 16 days. No change was observed in the mRNA levels. Using immunohistochemistry, a reduction in GFAP‐positive structures was revealed with a progressive trend in all the brains at 2, 7 and 16 days of treatment. In particular, a considerable reduction in GFAP‐positive fibres, with a different course, was observed in the ventricle areas and at the pial surface and in blood vessels after 16 days. Our experiments also showed a structural and chemical alteration of myelin and upregulation of mpz mRNA levels, the oligodendrocyte gene that is upregulated in experiments of neuronal injury, but not of plp1 and mbp mRNA levels, other myelin structural genes. These data confirm the toxic action of cadmium on the zebrafish brain. This action is time‐dependent and involves the glial cells, key components of the protection and function of nerve cells, hence the basis for many neurological diseases.

Perceived and Performed eHealth Literacy: Survey and Simulated Performance Test

Background Electronic health (eHealth) literacy of consumers is essential in order to improve information and communication technology (ICT) use for health purposes by ordinary citizens. However, performed eHealth literacy is seldom studied. Therefore, the present study assessed perceived and performed eHealth literacy using the recent conceptualization of health literacy skills. Objective The aim of this paper was to examine the association between perceived and performed eHealth literacies. Methods In total, 82 Israeli adults participated in the study, all 50 years and older, with a mean age of 67 (SD 11). Of the participants, 60% (49/82) were women and 72% (59/82) had a post-secondary education. The participants were first surveyed and then tested in a computer simulation of health-related Internet tasks. Performed, perceived (eHealth Literacy Scale, eHEALS), and evaluated eHealth literacy were assessed, and performed eHealth literacy was also recorded and re-evaluated later. Performance was scored for successful completion of tasks, and was also assessed by two researchers for motivation, confidence, and amount of help provided. Results The skills of accessing, understanding, appraising, applying, and generating new information had decreasing successful completion rates. Generating new information was least correlated with other skills. Perceived and performed eHealth literacies were moderately correlated (r=.34, P=.01) while facets of performance (ie, digital literacy and eHealth literacy) were highly correlated (r=.82, P<.001). Participants low and high in performed eHealth literacy were significantly different: low performers were older and had used the Internet for less time, required more assistance, and were less confident in their conduct than high performers. Conclusions The moderate association between perceived and performed eHealth literacy indicates that the latter should be assessed separately. In as much, the assessment of performed eHealth literacy in clinical settings should entail the structuring of tasks as well as shortening and automatizing the assessment.
Prognostic Markers for Poor Recovery After Mild Traumatic Brain Injury in Older Adults: A Pilot Cohort Study

Objective:To identify prognostic markers associated with poor recovery from mild traumatic brain injury (MTBI) in older adults. Setting:Three Ontario emergency departments. Participants:Forty-nine participants aged 65 years and older that visited an emergency department for MTBI. Design:Pilot prospective cohort study. Main Measures:Recovery from MTBI determined using the Rivermead Postconcussion symptom Questionnaire, the Glasgow Outcomes Scale—Extended, physical and mental health functioning (SF-12), and a single question on self-rated recovery assessed by telephone shortly after emergency department visit (baseline) and again 6 months later. Predictors were measured at baseline. Results:Markers potentially associated with poor recovery included reporting worse health 1 year before the injury, poor expectations for recovery, depression, and fatigue. Conclusion:Recovery after MTBI in older adults may be associated more with psychosocial than with biomedical or injury-related factors.
Faster Interleaved Modular Multiplication Based on Barrett and Montgomery Reduction Methods

This paper proposes two improved interleaved modular multiplication algorithms based on Barrett and Montgomery modular reduction. The algorithms are simple and especially suitable for hardware implementations. Four large sets of moduli for which the proposed methods apply are given and analyzed from a security point of view. By considering state-of-the-art attacks on public-key cryptosystems, we show that the proposed sets are safe to use, in practice, for both elliptic curve cryptography and RSA cryptosystems. We propose a hardware architecture for the modular multiplier that is based on our methods. The results show that concerning the speed, our proposed architecture outperforms the modular multiplier based on standard modular multiplication by more than 50 percent. Additionally, our design consumes less area compared to the standard solutions.
Optimism for the Future in Younger and Older Adults.

OBJECTIVES Research has suggested that older adults are less optimistic about their future than younger adults; however, a limitation of prior studies is that younger and older adults were forecasting to different ages and stages of life. To address this, we investigated whether there are age differences in future optimism when people project to the exact same age. We also tested whether optimism differs when projecting one's own future versus another person's future. METHOD Participants were 285 younger and 292 older adults recruited from Amazon Mechanical Turk. Participants completed writing and word-rating tasks in which they imagined their own future in 15 years, their own future at age 85, or the average person's future at age 85. RESULTS Younger adults were more optimistic than older adults about their own future in 15 years. In contrast, both age groups were similarly optimistic about their future at age 85 and expected it to be more positive than others' future at age 85. DISCUSSION Contrary to previous research, younger and older adults had comparable future forecasts when projecting to the exact same age. These findings emphasize the need to consider age and stage of life when examining age differences in future optimism.
Evaluation of Suppressive Effects of Tranilast on the Invasion/Metastasis Mechanism in a Murine Pancreatic Cancer Cell Line

Objectives Numerous studies have investigated the mechanism of the antitumor effect of tranilast, well known as an antiallergic drug. Herein, we investigated the mechanism of the antitumor effects of tranilast using murine PAN 02 cell line. Methods In an allograft mouse model, the number of metastatic sites in the liver was counted. Wound healing and chemoinvasion assay were performed to evaluate migration and invasive ability of PAN 02, respectively. Activities of matrix metalloproteinases (MMPs) were evaluated by gelatin zymography. The expression of cofactors in the activation of MMP-2 was assessed by immunohistochemical staining at the front of metastasis. Results The number of metastatic sites was reduced in tranilast-treated groups. Migration ability and tumor invasiveness were significantly inhibited by tranilast in a dose-dependent manner. Gelatin zymography revealed inhibition of MMP-2 activity. Immunohistochemical staining showed remarkable attenuation of tissue inhibitor of metalloproteinase (TIMP-) 2 expression in tranilast-treated groups. Conclusions Tissue inhibitor of metalloproteinase 2 is necessary for MMP-2 activation with interaction between membrane type 1-MMP and proMMP-2. These results suggested that tranilast may inhibit MMP-2 activation through attenuating TIMP-2 expression, resulting in inhibition of tumor invasion and metastasis. Our results showed possibility of tranilast in clinical application for novel cancer therapy.
Performance, body fat reserves and plasma metabolites in Brown Swiss dairy cows: Indoor feeding versus pasture‐based feeding

Feeding dairy cows indoors or on pasture affects not only labour, machinery and housing costs, but also animals' performance and metabolism. This study investigates the effects of indoor feeding (IF) with a partial-mixed ration (PMR) versus pasture-based feeding (PF) on milk production, fertility, backfat thickness (BFT), body weight (BW) loss and energy metabolism of Brown Swiss (BS) dairy cows with similar genetic production potential. The IF herd consisted of 13 cows fed a PMR composed of maize and grass silage plus protein concentrate according to each cow's requirements. The PF herd consisted of 14 cows offered barn-ventilated hay ad libitum after calving from January until March and grazed on semi-continuous pastures during the vegetation period. The IF cows produced more energy-corrected milk (ECM) per standard lactation (9,407 vs. 5,960 kg; p < .01), more milk fat (378 vs. 227 kg; p < .01) and milk protein (326 vs. 215 kg; p < .01). The calving interval (377 vs. 405 days; p < .01) and time empty (86 vs. 118 days; p < .01) were shorter in the PF compared to IF, possibly also due to different selection criteria for maintaining the respective seasonal calving rhythm. The empty body fat loss calculated according to BCS until its nadir was higher in IF cows (IF: 10.4 vs. PF: 4.8 MJ/day; p < .01), but no differences were noted in total body fat loss estimated via BFT (p = .24). However, PF had lower blood glucose concentration at all investigated time points, but no differences occurred in serum non-esterified fatty acid and β-hydroxybutyrate concentrations post-partum. In conclusion, BS cows were equally well suited for the IF with PMR and the PF system investigated here without developing a prominent metabolic load despite differences in nutrient supply. As such, investigated BS dairy cows in our trial seem to have a high capacity for metabolic adaptation to different production systems.
Flattened microvessel independently predicts poor prognosis of patients with non-small cell lung cancer

Angiogenesis plays an essential role in improving tumor progression, whereas, its value in prognosis predicting remains controversial, especially in non-small cell lung cancer (NSCLC). Most recently, microvessel pattern has been raised as a novel prognosis factor. In this study, flattened microvessel, evaluated by tumor microvessel aspect ratio (TMAR), was conducted as a prognostic factor in NSCLC patients. A total of 100 patients with NSCLC were retrospectively reviewed. Microvessel in tumor was visualized by immunochemistry staining and then TMAR was determined. The prognostic role of TMAR was evaluated by univariate and multivariate analysis. Most of intratumor microvessels were flattened with a median TMAR of 3.65 (range, 2.43 - 6.28). Patients were stratified into high TMAR group (TMAR ≥ 3.6) and low TMAR group (TMAR < 3.6). Compared with subpopulation with low TMAR, high TMAR had significantly high risk of cancer-related death (univariate analysis: HR = 5.06, 95% CI: 2.44-10.47, p<0.001; multivariate analysis: HR = 4.53, 95% CI: 1.70-12.06, p=0.002). In conclusion, the results of our study demonstrate that flattened microvessel in tumor tissue is a promising prognosis predictor of NSCLC patients.
Memory for Emotional Simulations

Mental simulations of future experiences are often concerned with emotionally arousing events. Although it is widely believed that mental simulations enhance future behavior, virtually nothing is known about how memory for these simulations changes over time or whether simulations of emotional experiences are especially well remembered. We used a novel paradigm that combined recently developed methods for generating simulations of future events and well-established procedures for testing memory to examine the retention of positive, negative, and neutral simulations over delays of 10 min and 1 day. We found that at the longer delay, details associated with negative simulations were more difficult to remember than details associated with positive or neutral simulations. We suggest that these effects reflect the influence of the fading-affect bias, whereby negative reactions fade more quickly than positive reactions, and that this influence results in a tendency to remember a rosy simulated future. We discuss implications of our findings for individuals with affective disorders, such as depression and anxiety.
Increased hepatic mitochondrial FA oxidation reduces plasma and liver TG levels and is associated with regulation of UCPs and APOC-III in rats

Hepatic mitochondrial function, APOC-III, and LPL are potential targets for triglyceride (TG)-lowering drugs. After 3 weeks of dietary treatment with the compound 2-(tridec-12-yn-1-ylthio)acetic acid (1-triple TTA), the hepatic mitochondrial FA oxidation increased more than 5-fold in male Wistar rats. Gene expression analysis in liver showed significant downregulation of APOC-III and upregulation of LPL and the VLDL receptor. This led to lower hepatic (53%) and plasma (73%) TG levels. Concomitantly, liver-specific biomarkers related to mitochondrial biogenesis and function (mitochondrial DNA, citrate synthase activity, and cytochrome c and TFAM gene expression) were elevated. Interestingly, 1-triple TTA lowered plasma acetylcarnitine levels, whereas the concentration of β-hydroxybutyrate was increased. The hepatic energy state was reduced in 1-triple TTA-treated rats, as reflected by increased AMP/ATP and decreased ATP/ADP ratios, whereas the energy state remained unchanged in muscle and heart. The 1-triple TTA administration induced gene expression of uncoupling protein (UCP)2 and UCP3 in liver. In conclusion, the 1-triple TTA-mediated clearance of blood TG may result from lowered APOC-III production, increased hepatic LPL gene expression, mitochondrial FA oxidation, and (re)uptake of VLDL facilitating drainage of FAs to the liver for β-oxidation and production of ketone bodies as extrahepatic fuel. The possibility that UCP2 and UCP3 mediate a moderate degree of mitochondrial uncoupling should be considered.
Stochastic Successive Convex Approximation for Non-Convex Constrained Stochastic Optimization

This paper proposes a constrained stochastic successive convex approximation (CSSCA) algorithm to find a stationary point for a general non-convex stochastic optimization problem, whose objective and constraint functions are non-convex and involve expectations over random states. Most existing methods for non-convex stochastic optimization, such as the stochastic (average) gradient and stochastic majorization-minimization, only consider minimizing a stochastic non-convex objective over a deterministic convex set. The proposed CSSCA algorithm can also handle stochastic non-convex constraints in optimization problems, and it opens the way to solving more challenging optimization problems that occur in many applications. The algorithm is based on solving a sequence of convex objective/feasibility optimization problems obtained by replacing the objective/constraint functions in the original problems with some convex surrogate functions. The CSSCA algorithm allows a wide class of surrogate functions and thus provides many freedoms to design good surrogate functions for specific applications. Moreover, it also facilitates parallel implementation for solving large-scale stochastic optimization problems, which arise naturally in today's signal processing such as machine learning and big data analysis. We establish the convergence of the CSSCA algorithm with a feasible initial point, and customize the algorithmic framework to solve several important application problems. Simulations show that the CSSCA algorithm can achieve superior performance over existing solutions.
PNF and manual therapy treatment results of patients with cervical spine osteoarthritis

PURPOSE: The aim of this study was to evaluate the effectiveness of PNF and manual therapy methods in the treatment of patients with cervical spine osteoarthritis, especially their efficacy in reducing pain and improving functionality in everyday life. Long-term results were also compared in order to determine which method of treatment is more effective. SUBJECTS AND METHODS: Eighty randomly selected females aged 45–65 were included in the study. They were randomly divided into two groups of 40 persons. One group received PNF treatment and the other received manual therapy (MAN.T). To evaluate functional capabilities, the Functional Rating Index was used. To evaluate changes in pain, a shortened version of the McGill Questionnaire was used. RESULT: The PNF group achieved a greater reduction in pain than the MAN.T group. The PNF group showed a greater improvement in performing daily activities such as sleeping, personal care, travelling, work, recreation, lifting, walking and standing as well as decreased intensity and frequency of pain compared to the MAN.T group. CONCLUSION: The PNF method proved to be more effective in both short (after two weeks) and long (after three months) term.
Securing and Scaling Cryptocurrencies Aviv Zohar

Bitcoin, a protocol for a new permissionless decentralized digital currency hailed the arrival of a new application domain for computer science. Following Bitcoin’s arrival, a series of innovations derived from the state of the art in several fields has been applied to cryptocurrencies, and has been slowly reshaping monetary and financial instruments on public distributed ledgers. It was soon clear however that Bitcoin and similar cryptocurrencies still require additional improvements. This challenging domain presents researchers in the field with new and exciting questions. I provide examples from two main research threads, related to the scalability of the protocol and to its underlying incentives.
Energy-Aware Joint Power and Rate Control in Overlay Cognitive Radio Networks: A Nash Bargaining Perspective

We investigate the energy-aware joint power and rate control in the overlay cognitive radio networks, and we expect to achieve the optimal performance tradeoff between individual fairness and network energy efficiency. Therefore, a quality of energy efficiency-based Nash bargaining cooperative game (QoE2-NBCG) is formulated with the aid of the newly-built 'energy-per-bit' individual utility function design in this paper. Mathematically, a multi-constrained optimization problem is formulated with Nash product function as the optimization object, which is consisted of the novel individual QoE2 utility function design. To reduce the implementation complexity, we utilize decomposition technique to decouple this multi-constrained problem. In addition, the existence and uniqueness of the socially optimal NB solutions are validated via theorems.
Health Outcomes of a Series of Bonny Method of Guided Imagery and Music Sessions: A Systematic Review

Background The Bonny Method of Guided Imagery and Music (GIM) is a music-centered approach to exploring consciousness for personal growth and transformation. Applications have been reported in a variety of clinical and nonclinical contexts. Objective The purpose of this study was to review evidence that a series of Bonny Method of GIM sessions may promote positive health outcomes in adults. Methods This systematic review examined randomized and nonrandomized controlled trials and repeated measures designs that reported psychological or physiological outcomes following a series of at least six individual Bonny Method of GIM sessions. Researchers assessed each study for risk of bias and computed effect sizes for outcome variables. Results Of 270 non-duplicate titles retrieved, nine met criteria for inclusion, and eight had moderate or low risk of bias. These included 275 participants 18-78 years of age representing a variety of populations. Multiple studies measured anxiety, depression, mood disturbance, interpersonal problems, quality of life, sense of coherence, and/or psychiatric symptoms and found medium to large effect sizes. Four included physiological measures (systolic and diastolic blood pressure, beta-endorphin, cortisol, and pain) and reported medium to large effect sizes, none of which were replicated across studies in this review. Conclusions Evidence is promising that a series of Bonny Method of GIM sessions may be effective for improving both psychological and physiological health and may be therapeutically indicated for adults seeking treatment with medical, mental health, and nonclinical needs. Further research is needed to replicate findings within outcomes and populations.
