<h4>Objectives</h4>The primary objective of this study is to test the hypothesis that administration of dexamethasone 20 mg is superior to a 6 mg dose in adult patients with moderate or severe ARDS due to confirmed COVID-19. The secondary objective is to investigate the efficacy and safety of dexamethasone 20 mg versus dexamethasone 6 mg. The exploratory objective of this study is to assess long-term consequences on mortality and quality of life at 180 and 360 days.<h4>Trial design</h4>REMED is ...[more]

Project description:BackgroundSince December 2019, SARS-CoV-2 virus has infected millions of people worldwide. In patients with COVID-19 pneumonia in need of oxygen therapy or mechanical ventilation, dexamethasone 6 mg per day is currently recommended. However, the dose of 6 mg of dexamethasone is currently being reappraised and may miss important therapeutic potential or may prevent potential deleterious effects of higher doses of corticosteroids.MethodsREMED is a prospective, open-label, randomised controlled trial testing the superiority of dexamethasone 20 mg (dexamethasone 20 mg on days 1-5, followed by dexamethasone 10 mg on days 6-10) vs 6 mg administered once daily intravenously for 10 days in adult patients with moderate or severe ARDS due to confirmed COVID-19. Three hundred participants will be enrolled and followed up for 360 days after randomization. Patients will be randomised in a 1:1 ratio into one of the two treatment arms. The following stratification factors will be applied: age, Charlson Comorbidity Index, CRP levels and trial centre. The primary endpoint is the number of ventilator-free days (VFDs) at 28 days after randomisation. The secondary endpoints are mortality from any cause at 60 days after randomisation; dynamics of the inflammatory marker, change in WHO Clinical Progression Scale at day 14; and adverse events related to corticosteroids and independence at 90 days after randomisation assessed by the Barthel Index. The long-term outcomes of this study are to assess long-term consequences on mortality and quality of life at 180 and 360 days. The study will be conducted in the intensive care units (ICUs) of ten university hospitals in the Czech Republic.DiscussionWe aim to compare two different doses of dexamethasone in patients with moderate to severe ARDS undergoing mechanical ventilation regarding efficacy and safety.Trial registrationEudraCT No. 2020-005887-70.

Project description:BackgroundThere is currently insufficient evidence on the safety and efficacy of antenatal corticosteroids in preventing mortality and severe morbidity amongst late preterm newborns in low-resource countries.MethodsWe conducted a double-blind, randomized trial in four hospitals in India between 26 December 2017 to 21 May 2020. Pregnant women at risk of imminent preterm birth between 34 weeks 0 days and 36 weeks 0 days of gestation were recruited. Women were randomly assigned (1:1) to a course of 6 mg intramuscular dexamethasone or an identical placebo. All trial participants, research staff and outcome assessors were masked to allocation. Primary outcomes were neonatal death, any baby death (stillbirth or neonatal death), severe neonatal respiratory distress and possible maternal bacterial infection. The study was registered with ANZCTR (ACTRN12617001494325) and CTRI (CTRI/2017/05/008721).FindingsWe randomized 782 women, 391 to each arm. Neonatal death occurred in 11 of 412 liveborn babies (2.7%) in the dexamethasone group and 12 of 425 liveborn babies (2.8%) in the placebo group (RR 0.95; 95% CI 0.42-2.12). Any baby death occurred in 16 of 417 infants (3.8%) in the dexamethasone group and 19 of 432 infants (4.4%) in the placebo group (RR 0.87; 95% CI 0.45-1.67). Severe neonatal respiratory distress was infrequent in both groups (0.8% vs 0.5%; RR 1.56; 95% CI 0.26-9.29). Possible maternal bacterial infection did not differ between groups (2.3% vs. 3.8%, RR 0.60; 95% CI 0.27-1.35). Fewer neonates in the dexamethasone group required resuscitation at birth (RR 0.38, CI 0.15-0.97). Other secondary outcomes were similar in the two arms. The trial was stopped due to lower than expected prevalence of primary outcomes and slow recruitment.InterpretationAntenatal dexamethasone did not result in a reduction in neonatal death, stillbirth or neonatal death, or severe neonatal respiratory distress in this trial. The overall trend of effects suggests that potential benefit of dexamethasone in late preterm cannot be excluded, and further trials are required.FundingThis trial was primarily funded by the Bill and Melinda Gates Foundation (Grant OPP1136821).

Project description:OBJECTIVE: To determine whether screening Danish men aged 65 or more for abdominal aortic aneurysms reduces mortality. DESIGN: Single centre randomised controlled trial. SETTING: All five hospitals in Viborg County, Denmark. PARTICIPANTS: All 12,639 men born during 1921-33 and living in Viborg County. In 1994 we included men born 1921-9 (64-73 years). We also included men who became 65 during 1995-8. INTERVENTIONS: Men were randomised to the intervention group (screening by abdominal ultrasonography) or control group. Participants with an abdominal aortic aneurysm > 5 cm were referred for surgical evaluation, and those with smaller aneurysms were offered annual scans. OUTCOME MEASURES: Specific mortality due to abdominal aortic aneurysm, overall mortality, and number of planned and emergency operations for abdominal aortic aneurysms. RESULTS: 4860 of 6333 men were screened (attendance rate 76.6%). 191 (4.0% of those screened) had abdominal aortic aneurysms. The mean follow-up time was 52 months. The screened group underwent 75% (95% confidence interval 51% to 91%) fewer emergency operations than the control group. Deaths due to abdominal aortic aneurysms occurred in nine patients in the screened group and 27 in the control group. The number needed to screen to save one life was 352. Specific mortality was significantly reduced by 67% (29% to 84%). Mortality due to non-abdominal aortic aneurysms was non-significantly reduced by 8%. The benefits of screening may increase with time. CONCLUSION: Mass screening for abdominal aortic aneurysms in Danish men aged 65 or more reduces mortality.

Project description:IntroductionMinimally invasive cardiac surgery (MICS) is important for enhanced recovery in cardiac surgery. However, the incidence of chronic postsurgical pain (CPSP) is high and is associated with worsened quality of recovery and life, as well as raised short-term or long-term mortality. The mechanism is not clear, and there is still a lack of safe and effective preventive measures.Methods and analysisThe Paravertebral Adjunctive Dexamethasone Palmitate Reducing chronic pain After cardiac surgery (PANDORA) trial is a parallel-group, double-blinded, randomised controlled, single-centre study recruiting 902 participants undergoing MICS. Participants will be randomised in a 1:1 ratio to dexamethasone palmitate (D-PAL) emulsion group and dexamethasone (DSP) group. To investigate the effect of a single bolus perineural administration of D-PAL as an adjuvant treatment to a standard thoracic paravertebral block (TPVB) with ropivacaine decreases the incidence of CPSP in adult patients as compared with single bolus perineural administration of DSP combined with ropivacaine in TPVB. The primary endpoint is the incidence of chronic postoperative pain at 3 months following surgery defined as per the updated International Classification of Diseases. CPSP is defined as a new development of pain or increase in the intensity of pain at the surgical area or projected onto the innervation area of a nerve in this area after a surgical procedure that persists for at least 3 months. The nature and intensity of pain will be evaluated with a Brief Pain Inventory Short Form (BPI-SF) questionnaire.Ethics and disseminationThe trial was approved by the Ethics Committee of Xijing Hospital, the First Affiliated Hospital of Air Force Military Medical University (KY20232194-C-1). Results will be submitted for publication in peer-reviewed journals and presented at academic meetings.Trial registration numberClinicalTrials.gov, NCT05920967.

Project description:BackgroundSystemic corticosteroids are commonly prescribed for palliation of dyspnoea in patients with cancer, despite scarce evidence to support their use. We aimed to assess the effect of high-dose dexamethasone versus placebo on cancer-related dyspnoea.MethodsThe parallel-group, double-blind, randomised, controlled ABCD (Alleviating Breathlessness in Cancer Patients with Dexamethasone) trial was done at the at the University of Texas MD Anderson Cancer Center and the general oncology clinic at Lyndon B Johnson General Hospital (both in Houston, TX, USA). Ambulatory patients with cancer, aged 18 years or older, and with an average dyspnoea intensity score on an 11-point numerical rating scale (NRS; 0=none, 10=worst) over the past week of 4 or higher were randomly assigned (2:1) to receive dexamethasone 8 mg orally every 12 h for 7 days followed by 4 mg orally every 12 h for 7 days, or matching placebo capsules for 14 days. Pharmacists did permuted block randomisation with a block size of six, and patients were stratified by baseline dyspnoea score (4-6 vs 7-10) and study site. Patients, research staff, and clinicians were masked to group assignment. The primary outcome was change in dyspnoea NRS intensity over the past 24 h from baseline to day 7 (±2 days). Analyses were done by modified intention-to-treat (ie, including all patients who were randomly assigned and started the study treatment, regardless of whether they completed the study). Enrolment was stopped after the second preplanned interim analysis, when the futility criterion was met. This study is registered with ClinicalTrials.gov (NCT03367156) and is now completed.FindingsBetween Jan 11, 2018, and April 23, 2021, we screened 2867 patients, enrolled 149 patients, and randomly assigned 128 to dexamethasone (n=85) or placebo (n=43). The mean change in dyspnoea NRS intensity from baseline to day 7 (±2 days) was -1·6 (95% CI -2·0 to -1·2) in the dexamethasone group and -1·6 (-2·3 to -0·9) in the placebo group, with no significant between-group difference (mean 0 [95% CI -0·8 to 0·7]; p=0·48). The most common all-cause grade 3-4 adverse events were infections (nine [11%] of 85 patients in the dexamethasone group vs three [7%] of 43 in the placebo group), insomnia (seven [8%] vs one [2%]), and neuropsychiatric symptoms (three [4%] vs none [0%]). Serious adverse events, all resulting in hospital admissions, were reported in 24 (28%) of 85 patients in the dexamethasone group and in three (7%) of 43 patients in the placebo group. No treatment-related deaths occurred in either group.InterpretationHigh-dose dexamethasone did not improve dyspnoea in patients with cancer more effectively than placebo and was associated with a higher frequency of adverse events. These data suggest that dexamethasone should not be routinely given to unselected patients with cancer for palliation of dyspnoea.FundingUS National Cancer Institute.

Project description:To quantify and draw inferences on the clinical effectiveness of platelet-rich therapy in the management of patients with a typical osteoporotic fracture of the hip.Single centre, parallel group, participant-blinded, randomised controlled trial.UK Major Trauma Centre.200 of 315 eligible patients aged 65 years and over with any type of intracapsular fracture of the proximal femur. Patients were excluded if their fracture precluded internal fixation.Participants underwent internal fixation of the fracture with cannulated screws and were randomly allocated to receive an injection of platelet-rich plasma into the fracture site or not.Failure of fixation within 12 months, defined as any revision surgery.Primary outcome data were available for 82 of 101 and 78 of 99 participants allocated to test and control groups, respectively; the remainder died prior to final follow-up. There was an absolute risk reduction of 5.6% (95% CI -10.6% to 21.8%) favouring treatment with platelet-rich therapy (?(2) test, p=0.569). An adjusted effect estimate from a logistic regression model was similar (OR=0.71, 95% CI 0.36 to 1.40, z test; p=0.325). There were no significant differences in any of the secondary outcome measures excepting length of stay favouring treatment with platelet-rich therapy (median difference 8 days, Mann-Whitney U test; p=0.03). The number and distribution of adverse events were similar. Estimated cumulative incidence functions for the competing events of death and revision demonstrated no evidence of a significant treatment effect (HR 0.895, 95% CI 0.533 to 1.504; p=0.680 in favour of platelet-rich therapy).No evidence of a difference in the risk of revision surgery within 1 year in participants treated with platelet-rich therapy compared with those not treated. However, we cannot definitively exclude a clinically meaningful difference.Current Controlled Trials, ISRCTN49197425, http://www.controlled-trials.com/ISRCTN49197425.
