Outcomes of Two Trials of Oxygen-Saturation Targets in Preterm Infants.

Abstract: BACKGROUND: The safest ranges of oxygen saturation in preterm infants have been the subject of debate. METHODS: In two trials, conducted in Australia and the United Kingdom, infants born before 28 weeks' gestation were randomly assigned to either a lower (85 to 89%) or a higher (91 to 95%) oxygen-saturation range. During enrollment, the oximeters were revised to correct a calibration-algorithm artifact. The primary outcome was death or disability at a corrected gestational age of 2 years; this outcome was evaluated among infants whose oxygen saturation was measured with any study oximeter in the Australian trial and those whose oxygen saturation was measured with a revised oximeter in the U.K. trial. RESULTS: After 1135 infants in Australia and 973 infants in the United Kingdom had been enrolled in the trial, an interim analysis showed increased mortality at a corrected gestational age of 36 weeks, and enrollment was stopped. Death or disability in the Australian trial (with all oximeters included) occurred in 247 of 549 infants (45.0%) in the lower-target group versus 217 of 545 infants (39.8%) in the higher-target group (adjusted relative risk, 1.12; 95% confidence interval [CI], 0.98 to 1.27; P=0.10); death or disability in the U.K. trial (with only revised oximeters included) occurred in 185 of 366 infants (50.5%) in the lower-target group versus 164 of 357 infants (45.9%) in the higher-target group (adjusted relative risk, 1.10; 95% CI, 0.97 to 1.24; P=0.15). In post hoc combined, unadjusted analyses that included all oximeters, death or disability occurred in 492 of 1022 infants (48.1%) in the lower-target group versus 437 of 1013 infants (43.1%) in the higher-target group (relative risk, 1.11; 95% CI, 1.01 to 1.23; P=0.02), and death occurred in 222 of 1045 infants (21.2%) in the lower-target group versus 185 of 1045 infants (17.7%) in the higher-target group (relative risk, 1.20; 95% CI, 1.01 to 1.43; P=0.04). In the group in which revised oximeters were used, death or disability occurred in 287 of 580 infants (49.5%) in the lower-target group versus 248 of 563 infants (44.0%) in the higher-target group (relative risk, 1.12; 95% CI, 0.99 to 1.27; P=0.07), and death occurred in 144 of 587 infants (24.5%) versus 99 of 586 infants (16.9%) (relative risk, 1.45; 95% CI, 1.16 to 1.82; P=0.001). CONCLUSIONS: Use of an oxygen-saturation target range of 85 to 89% versus 91 to 95% resulted in nonsignificantly higher rates of death or disability at 2 years in each trial but in significantly increased risks of this combined outcome and of death alone in post hoc combined analyses.

SCOPE 2021: a new scorecard for osteoporosis in Europe

Abstract: This scorecard summarises key indicators of the burden of osteoporosis and its management in the 27 member states of the European Union, as well as the UK and Switzerland. The resulting scorecard elements, assembled on a single sheet, provide a unique overview of osteoporosis in Europe. The scorecard for osteoporosis in Europe (SCOPE) is a project of the International Osteoporosis Foundation (IOF) that seeks to raise awareness of osteoporosis care in Europe. The aim of this project was to develop a scorecard and background documents to draw attention to gaps and inequalities in the provision of primary and secondary prevention of fractures due to osteoporosis. The SCOPE panel reviewed the information available on osteoporosis and the resulting fractures for each of the 27 countries of the European Union plus the UK and Switzerland (termed EU27+2). The information obtained covered four domains: background information (e.g. the burden of osteoporosis and fractures), policy framework, service provision and service uptake, e.g. the proportion of men and women at high risk that do not receive treatment (the treatment gap). There was a marked difference in fracture risk among the EU27+2 countries. Of concern was the marked heterogeneity in the policy framework, service provision and service uptake for osteoporotic fracture that bore little relation to the fracture burden. For example, despite the wide availability of treatments to prevent fractures, in the majority of the EU27+2, only a minority of patients at high risk receive treatment even after their first fracture. The elements of each domain in each country were scored and coded using a traffic light system (red, orange, green) and used to synthesise a scorecard. The resulting scorecard elements, assembled on a single sheet, provide a unique overview of osteoporosis in Europe. The scorecard enables healthcare professionals and policy makers to assess their country’s general approach to the disease and provide indicators to inform the future provision of healthcare.

Leader autonomy support in the workplace: A meta-analytic review.

Abstract: Leader autonomy support (LAS) refers to a cluster of supervisory behaviors that are theorized to facilitate self-determined motivation in employees, potentially enabling well-being and performance. We report the results of a meta-analysis of perceived LAS in work settings, drawing from a database of 754 correlations across 72 studies (83 unique samples, N = 32,870). Results showed LAS correlated strongly and positively with autonomous work motivation, and was unrelated to controlled work motivation. Correlations became increasingly positive with the more internalized forms of work motivation described by self-determination theory. LAS was positively associated with basic needs, well-being, and positive work behaviors, and was negatively associated with distress. Correlations were not moderated by the source of LAS, country of the sample, publication status, or the operationalization of autonomy support. In addition, a meta-analytic path analysis supported motivational processes that underlie LAS and its consequences in workplaces. Overall, our findings lend support for autonomy support as a leadership approach that is consistent with self-determination and optimal functioning in work settings.

Clinical characteristics of patients from the worldwide registry on peripartum cardiomyopathy (PPCM)

Abstract: Aims The purpose of this study is to describe disease presentation, co-morbidities, diagnosis and initial therapeutic management of patients with peripartum cardiomyopathy (PPCM) living in countries belonging to the European Society of Cardiology (ESC) vs. non-ESC countries. Methods and results Out of 500 patients with PPCM entered by 31 March 2016, we report on data of the first 411 patients with completed case record forms (from 43 countries) entered into this ongoing registry. There were marked differences in socio-demographic parameters such as Human Development Index, GINI index on inequality, and Health Expenditure in PPCM patients from ESC vs. non-ESC countries (P < 0.001 each). Ethnicity was Caucasian (34%), Black African (25.8%), Asian (21.8%), and Middle Eastern backgrounds (16.4%). Despite the huge disparities in socio-demographic factors and ethnic backgrounds, baseline characteristics are remarkably similar. Drug therapy initiated post-partum included ACE inhibitors/ARBs and mineralocorticoid receptor antagonists with identical frequencies in ESC vs. non-ESC countries. However, in non-ESC countries, there was significantly less use of beta-blockers (70.3% vs. 91.9%) and ivabradine (1.4% vs. 17.1%), but more use of diuretics (91.3% vs. 68.8%), digoxin (37.0% vs. 18.0%), and bromocriptine (32.6% vs. 7.1%) (P < 0.001). More patients in non-ESC vs. ESC countries continued to have symptomatic heart failure after 1 month (92.3% vs. 81.3%, P < 0.001). Venous thrombo-embolic events, arterial embolizations, and cerebrovascular accidents were documented in 28 of 411 patients (6.8%). Neonatal death rate was 3.1%. Conclusion PPCM occurs in women from different ethnic backgrounds globally. Despite marked differences in socio-economic background, mode of presentation was largely similar. Embolic events and persistent heart failure were common within 1 month post-diagnosis and required intensive, multidisciplinary management.
