Among patients with unstable angina or myocardial infarction without ST-segment elevation, prasugrel did not significantly reduce the frequency of the primary end point, as compared with clopidogrel, and similar risks of bleeding were observed.

Cardiovascular disease is strongly age-related, and is the leading cause of death in older people. Several well-publicized trials have recently reported that statin drugs (HMG CoA reductase inhibitors) are effective in lowering cholesterol and in reducing the risk of myocardial infarction and stroke. In order to determine whether the results of these trials are relevant to our ageing population, we examined the representation of older people and women in randomized controlled trials of statin drugs. A systematic search of the medical literature from 1990 to 1999 was done to identify randomized placebo-controlled trials of statin drugs which evaluated clinical end-points-myocardial infarction, stroke or death. We identified 19 trials: 15 secondary prevention and four primary prevention. The mean age, age range and gender of the participants in these trials were determined. In the secondary prevention trials, the total number of patients randomized was 31683, with a combined mean age of 58.1 years. No trial enrolled people beyond the age of 75 years, and only 23% of the trial population was female. The four primary prevention trials randomized a combined total of 14 557 subjects with a mean age of 56.9 years. Only 10% of study participants were female. Statin drug trials have suffered from age and gender bias, having been mainly conducted in middle-aged male populations. The extrapolation of evidence from these trials to older people and women needs further evaluation.
HighlightsDengue induced Hemophagocytic lymphohistiocytosis (HLH), is a serious entity and can adversely affect the course of the infection.HLH is a potentially life threatening disorder and early diagnosis and management is crucial for successful outcome.A disproportionately high ferritin level should trigger investigations for HLH.
Background This study aimed to determine the impact of pulmonary complications on death after surgery both before and during the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. Methods This was a patient-level, comparative analysis of two, international prospective cohort studies: one before the pandemic (January–October 2019) and the second during the SARS-CoV-2 pandemic (local emergence of COVID-19 up to 19 April 2020). Both included patients undergoing elective resection of an intra-abdominal cancer with curative intent across five surgical oncology disciplines. Patient selection and rates of 30-day postoperative pulmonary complications were compared. The primary outcome was 30-day postoperative mortality. Mediation analysis using a natural-effects model was used to estimate the proportion of deaths during the pandemic attributable to SARS-CoV-2 infection. Results This study included 7402 patients from 50 countries; 3031 (40.9 per cent) underwent surgery before and 4371 (59.1 per cent) during the pandemic. Overall, 4.3 per cent (187 of 4371) developed postoperative SARS-CoV-2 in the pandemic cohort. The pulmonary complication rate was similar (7.1 per cent (216 of 3031) versus 6.3 per cent (274 of 4371); P = 0.158) but the mortality rate was significantly higher (0.7 per cent (20 of 3031) versus 2.0 per cent (87 of 4371); P < 0.001) among patients who had surgery during the pandemic. The adjusted odds of death were higher during than before the pandemic (odds ratio (OR) 2.72, 95 per cent c.i. 1.58 to 4.67; P < 0.001). In mediation analysis, 54.8 per cent of excess postoperative deaths during the pandemic were estimated to be attributable to SARS-CoV-2 (OR 1.73, 1.40 to 2.13; P < 0.001). Conclusion Although providers may have selected patients with a lower risk profile for surgery during the pandemic, this did not mitigate the likelihood of death through SARS-CoV-2 infection. Care providers must act urgently to protect surgical patients from SARS-CoV-2 infection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
