General hospital staff worries, perceived sufficiency of information and associated psychological distress during the A/H1N1 influenza pandemic

<p>Abstract</p> <p>Background</p> <p>Health care workers (HCWs) presented frequent concerns regarding their health and their families' health and high levels of psychological distress during previous disease outbreaks, such as the SARS outbreak, which was associated with social isolation and intentional absenteeism. We aimed to assess HCWs concerns and anxiety, perceived sufficiency of information, and intended behavior during the recent A/H1N1 influenza pandemic and their associations with psychological distress.</p> <p>Method</p> <p>Between September 1^stand 30^th, 2009, 469 health-care workers (HCWs) of a tertiary teaching hospital completed a 20-item questionnaire regarding concerns and worries about the new A/H1N1 influenza pandemic, along with Cassileth's Information Styles Questionnaire (part-I) and the GHQ-28.</p> <p>Results</p> <p>More than half of the present study's HCWs (56.7%) reported they were worried about the A/H1N1 influenza pandemic, their degree of anxiety being moderately high (median 6/9). The most frequent concern was infection of family and friends and the health consequences of the disease (54.9%). The perceived risk of being infected was considered moderately high (median 6/9). Few HCWs (6.6%) had restricted their social contacts and fewer (3.8%) felt isolated by their family members and friends because of their hospital work, while a low percentage (4.3%) indented to take a leave to avoid infection. However, worry and degree of worry were significantly associated with intended absenteeism (p < 0.0005), restriction of social contacts (p < 0.0005), and psychological distress (p = 0.036). Perceived sufficiency of information about several aspects of the A/H1N1 influenza was moderately high, and the overall information about the A/H1N1 influenza was considered clear (median 7.4/9). Also, perceived sufficiency of information for the prognosis of the infection was significantly independently associated with the degree of worry about the pandemic (p = 0.008).</p> <p>Conclusions</p> <p>A significant proportion of HCWs experienced moderately high anxiety about the pandemic, and their degree of worry was an independent correlate of psychological distress. Since perceived sufficiency of information about the A/H1N1 influenza prognosis was associated with reduced degree of worry, hospital managers and consultation-liaison psychiatry services should try to provide for HCWs' need for information, in order to offer favourable working conditions in times of extreme distress, such as the current and future pandemics.</p

Sex- and age-related differences in the management and outcomes of chronic heart failure: an analysis of patients from the ESC HFA EORP Heart Failure Long-Term Registry

Aims: This study aimed to assess age- and sex-related differences in management and 1-year risk for all-cause mortality and hospitalization in chronic heart failure (HF) patients. Methods and results: Of 16 354 patients included in the European Society of Cardiology Heart Failure Long-Term Registry, 9428 chronic HF patients were analysed [median age: 66 years; 28.5% women; mean left ventricular ejection fraction (LVEF) 37%]. Rates of use of guideline-directed medical therapy (GDMT) were high (angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, beta-blockers and mineralocorticoid receptor antagonists: 85.7%, 88.7% and 58.8%, respectively). Crude GDMT utilization rates were lower in women than in men (all differences: P\ua0 64 0.001), and GDMT use became lower with ageing in both sexes, at baseline and at 1-year follow-up. Sex was not an independent predictor of GDMT prescription; however, age >75 years was a significant predictor of GDMT underutilization. Rates of all-cause mortality were lower in women than in men (7.1% vs. 8.7%; P\ua0=\ua00.015), as were rates of all-cause hospitalization (21.9% vs. 27.3%; P\ua075 years. Conclusions: There was a decline in GDMT use with advanced age in both sexes. Sex was not an independent predictor of GDMT or adverse outcomes. However, age >75 years independently predicted lower GDMT use and higher all-cause mortality in patients with LVEF 6445%

Energy Harvesting Smart Textiles

The ever-increasing population of the world is putting a significant demand on the need for multifunctional electronic devices and electricity to power them. This growing demand has led to an enhanced focus on the development of energy harvesting techniques based on renewable and ambient sources. Although materials having unique properties such as photovoltaic, piezoelectric and triboelectric have been known for a long time and have been utilized usually in the form of thin-film structures, their utilization in the form of textile structures for energy harvesting is a relatively new area of research. This chapter will focus on the recent advances in the area of photovoltaic, piezoelectric and triboelectric energy-generating textile structures and the fundamentals of these unique properties, production methods and textile-based energy storage. Finally, expected future trends in the fabrication and application of textile-based energy harvesting and storage will be discussed

Early detection of cardiac involvement in systemic sclerosis assessed by tissue-Doppler echocardiography: relationship with neurohormonal activation and endothelial dysfunction.

OBJECTIVE: Cardiopulmonary complications are common in patients with systemic sclerosis (SSc). We assessed cardiac involvement in patients with SSc using echocardiography and investigated the association of N-terminal pro-brain natriuretic peptide (NT-proBNP) and asymmetric dimethylarginine (ADMA) with echocardiographic measures of myocardial function in sera of patients with SSc who had no symptoms of heart failure. METHODS: We prospectively studied 52 patients with SSc (mean age 55.7 +/- 10.1 yrs, 51 women), with conventional and tissue-Doppler echocardiography. Plasma NT-proBNP and ADMA levels were measured in all patients. Data were compared with those obtained from 25 healthy controls comparable for age and sex. RESULTS: Patients with SSc had impaired left ventricular (LV) and right ventricular diastolic function expressed by inverted ratio of peak early to peak late transmitral (Mit E/A) and transtricuspid velocity and increased left atrial diameter compared with controls. Peak systolic mitral lateral annular motion velocity and peak early diastolic mitral lateral annular motion velocity (LV Em) were lower, while LV E/Em ratio was higher, in patients with SSc compared to controls. ADMA was significantly related with LV Em and E/Em ratio. NT-proBNP was associated with Mit E, Mit E/A ratio and mitral deceleration time. Significant correlation was also observed between NT-proBNP and ADMA levels. CONCLUSION: Depressed cardiac function is common, even in asymptomatic patients with SSc. NT-proBNP and ADMA are significantly correlated with echocardiographic abnormalities, providing a potent link for cardiac function, neuroendocrine derangement, and endothelial dysfunction in patients with SSc who have cardiac disease
