Objective To evaluate associations of high-sensitivity cardiac troponin-T (cTnT) with cardiovascular disease (CVD), heart failure (HF), and mortality in community-dwelling women and men. Participants and methods A total of 8226 adults from the Prevention of Renal and Vascular End-stage Disease (PREVEND) cohort (1997-1998) were enrolled in a prospective observational study (mean age 49 years; 50.2% women). Sex-specific associations of cTnT levels with future clinical outcomes were evaluated using adjusted Cox-regression models. Results Measurable cTnT levels (≥3 ng/L) were detected in 1102 women (26.7%) and in 2396 men (58.5%). Baseline cTnT levels were associated with a greater risk of developing CVD in women than men [Hazard ratio (HRwomen), 1.48 per unit increase in log2-cTnT; 95% CI, 1.21 to 1.81 vs HRmen, 1.20; 95% CI, 1.07 to 1.35; Pinteraction less then .001]. Similar sex-related differences were observed for HF (Pinteraction= .005) and mortality (Pinteraction= .008). Further, compared with referent category (cTnT less then 3 ng/L), women with cTnT levels greater than or equal to 6 ng/L had a significantly increased risk for CVD (HR, 2.30; 95% CI, 1.45 to 3.64), HF (HR, 2.86; 95% CI, 1.41 to 5.80), and mortality (HR, 2.65; 95% CI, 1.52 to 4.61), whereas men with cTnT levels greater than or equal to 6 ng/L had a significantly increased risk only for CVD (HR, 1.51; 95% CI, 1.07 to 2.13). Conclusion Baseline cTnT levels were associated with future CVD, HF, and mortality in both sexes, and these associations were stronger in women. Future studies are needed to determine the value of cTnT in early diagnosis of CVD, particularly in women.Objective To report the first randomized controlled trial to investigate if immersive virtual reality (VR) treatment can reduce patient perceptions of anxiety compared with a tablet-based control treatment in adults undergoing a first-time sternotomy. Methods Twenty first-time sternotomy patients were prospectively randomized (blinded to investigator) to a control or VR intervention. The VR intervention was a game module "Bear Blast" (AppliedVR) displayed using a Samsung Gear Oculus VR headset. The control intervention was a tablet-based game with comparable audio, visual, and tactile components. The State-Trait Anxiety Inventory was administered before and after the assigned intervention. Self-reported anxiety measures between the control and VR groups were evaluated using an unpaired t test. Changes in self-reported anxiety measures pre- and post-intervention were evaluated with a paired t test for both the control and VR groups. The study took place from May 1, 2017, through January 1, 2019 (Institutional Review Board 16-009784). Results Both control and VR groups were 90.0% male, with a mean ± SD age of 63.4 ± 9.11 and 69.5 ± 6.9 years, respectively. VR users experienced significant reductions in feeling tense and strained, and significant improvements in feeling calm when compared with tablet controls (P less then 0.05). They also experienced significant reductions in feeling strained, upset, and tense when compared with their own self-reported anxiety measure pre- and post-intervention (P less then 0.05). Critically, control patients had no change in these categories. Streptozotocin nmr Conclusion Immersive VR is an effective, nonpharmacologic approach to reducing preoperative anxiety in adults undergoing cardiac surgery and shows the validity and utility of this technology in adult patients.ObjectiveThe aim of this study was to understand, from the perspective of policy makers, who holds the responsibility for driving evidence-based policy to reduce the high burden of cardiovascular disease (CVD) in rural Australia.MethodsQualitative interviews were conducted with policy makers at the local, state and federal government levels in Australia (n=21). Analysis was conducted using the Conceptual Framework for Understanding Rural and Remote Health to understand perceptions of policy makers around who holds the key responsibility in driving evidence-based policy.ResultsAt all levels of government, there were multiple examples of disconnect in the understanding of who is responsible for driving the generation of evidence-based policy to reduce CVD in rural areas. Policy makers suggested that the rural communities themselves, health services, health professionals, researchers and the health sector as a whole hold large responsibilities in driving evidence-based policy to address CVD in rural areas. Withi The results reported here are highly relevant to the Australian context, but also reflect similar findings internationally, namely that a lack of clarity among policy stakeholders appears to contribute to reduced action in addressing preventable health inequalities in disadvantaged populations. This paper provides evidence for policy makers and public health professionals to advocate for clear policy roles and direction in rural Australia.Introduction In December 2019, an outbreak of pneumonia caused by a novel coronavirus occurred in Wuhan, the capital of Central China's Hubei Province and has been declared a public health emergency of international concern by the World Health Organization since January 2020. Material and methods A comprehensive search using the PubMed database was carried out to summarize the latest published information about the epidemiology, definition, pathogenesis, clinical characteristics, treatment options, prognosis and prevention of coronavirus disease 2019. Discussion This new strain of coronavirus, named severe acute respiratory syndrome coronavirus 2, enters human cells that express angiotensin-converting enzyme II receptors, which exist in the respiratory, gastrointestinal and genitourinary tracts and heart, causing coronavirus disease. Transmission occurs essentially through the respiratory tract and the main symptoms are fever, cough and dyspnea. Diagnosis is based on epidemiological, clinical and imaging features and confirmed by nucleic acid testing. Conclusion Despite intensive research, the exact origin of the virus and pathophysiology of coronavirus disease is not yet completely known, and clinically approved vaccines and drugs that target severe acute respiratory syndrome coronavirus 2 are lacking.
