Extensive research has identified enterovirus (EV) infections as key environmental triggers of type 1 diabetes. However, the underlying molecular mechanisms via which EVs contribute to the pathogenesis of type 1 diabetes remain unclear. Given that EVs dysregulate host microRNAs (miRNAs), which function as key regulators of β-cell biology, we investigated the impact of coxsackievirus B5 (CVB5) infection on the cellular expression of miRNAs within human islets. Using high-throughput quantitative PCR nanofluidics arrays, the expression of 754 miRNAs was examined in CVB5-infected human pancreatic islets. In total, 33 miRNAs were significantly dysregulated (≥ threefold difference) in the infected compared with control islets (P < 0.05). Subsequently, these differentially expressed miRNAs were predicted to target mRNAs of 57 known type 1 diabetes risk genes that collectively mediate various biological processes, including the regulation of cell proliferation, cytokine production, the innate immune response, and apoptosis. In conclusion, we report the first global miRNA expression profiling of CVB5-infected human pancreatic islets. We propose that EVs disrupt the miRNA-directed suppression of proinflammatory factors within β-cells, thereby resulting in an exacerbated antiviral immune response that promotes β-cell destruction and eventual type 1 diabetes.

The objective of this study was to assess evidence for the efficacy and effectiveness of Chinese qigong exercise in rehabilitative programs among cardiac patients. Thirteen databases were searched through to November 2010, and all controlled clinical trials on Chinese qigong exercise among patients with chronic heart diseases were included. For each included study, data was extracted and validity was assessed. Study quality was evaluated and summarized using both the Jadad Scale and the criteria for levels of evidence. Seven randomized controlled trials (RCTs) and one non-randomized controlled clinical trial (CCT) published between 1988 and 2007 met the inclusion criteria. In total, these studies covered 540 patients with various chronic heart diseases including atrial fibrillation, coronary artery disease, myocardial infarct, valve replacement, and ischemic heart disease. Outcome measures emerged in these studies included subjective outcomes such as symptoms and quality of life; and objective outcomes such as blood pressure, ECG findings, and exercise capacity, physical activity, balance, co-ordination, heart rate, and oxygen uptake. Overall, these studies suggest that Chinese qigong exercise seems to be an optimal option for patients with chronic heart diseases who were unable to engage in other forms of physical activity; however, its efficacy and effectiveness in cardiac rehabilitation programs should be further tested.

The 12-item CZBI-Short is a concise, reliable, and valid instrument to assess burden in Chinese dementia caregivers in clinical and social care settings.

Objective The palliative journey can be emotionally stressful for both patients with advanced cancer and their families. Psychological resilience is crucial in aiding with patients' adaptation and post‐traumatic growth. The aim of this systematic review was to critically examine the definitions of psychological resilience and its associated factors in palliative patients with advanced cancer. Methods Four databases were systematically searched from inception to August 2020. Both qualitative and quantitative studies that examined factors associated with psychological resilience in a sample of patients with advanced cancer undergoing palliative care were included. Results A total of 15 studies met the criteria, of which 10 were qualitative and five were quantitative. Nine studies included a definition of psychological resilience, from which five common themes of buffering, adaptation, resources, recovery, and growth were derived. The quantitative studies found association between resilience and hope, independence, social support, fatigue, emotional distress, and coping strategies. The qualitative studies reported additional sources of resilience such as spirituality, social support, prior experience dealing with illness and life adversity, meaning‐making, reconciling with life's finiteness, acceptance of illness, control, determination, positive attitude, dignity, engagement with palliative care and quality of life being supported by palliative care. Conclusions More research is needed for developing an overarching definition of psychological resilience in palliative advanced cancer patients that acknowledges and appreciates the contextual sensitivity of this concept among different cultural groups. Further studies are also needed to examine a holistic range of bio‐psycho‐socio‐spiritual factors associated with psychological resilience among these patients and their families.
