Optimal duration of therapy combining ranitidine bismuth citrate with clarithromycin and metronidazole in the eradication of Helicobacter pylori infe…
1999
Background: Ranitidine bismuth citrate (RBC) co-prescribed with clarithromycin and metronidazole for 1 week has been shown to be an effective eradicating regimen for Helicobacter pylori. Aim: To determine the optimal duration of this regimen. Methods: A series of 165 dyspeptic patients were recruited for this randomized, open, parallel-group study. They were subdivided into three groups receiving RBC 400 mg b.d. plus clarithromycin 250 mg b.d. and metronidazole 500 mg b.d. for three different periods (4, 7 and 10 days). H. pylori infection was assessed by the concomitant positivity of CLO-test and histology performed at the pre-entry endoscopy. The bacterium was considered eradicated on the…
Budesonide induces remission more effectively than prednisone in a controlled trial of patients with autoimmune hepatitis.
2010
Autoimmune hepatitis (AIH) is a chronic liver disease associated with cirrhosis and liver failure. Corticosteroid therapy induces long-term remission but has many side effects. We compared the effects of budesonide (a steroid that is rapidly metabolized, with low systemic exposure) and prednisone, both in combination with azathioprine.We performed a 6-month, prospective, double-blind, randomized, active-controlled, multicenter, phase IIb trial of patients with AIH without evidence of cirrhosis who were given budesonide (3 mg, three times daily or twice daily) or prednisone (40 mg/d, tapered to 10 mg/d); patients also received azathioprine (1-2 mg/kg/d). Treatment was followed by a 6-month, …
Fasting During Pregnancy and Children's Academic Performance
2011
Conventionally studied educational interventions tend to be costly and may be subject to “fade out”. In contrast, experiences during the prenatal period can have large and persistent effects on academic performance, even when quite brief. In this paper, we consider a relatively mild and commonly-experienced prenatal exposure – that occasioned by daytime fasting during the lunar month of Ramadan. In register data from England, we find that test scores at age seven are approximately .05 to .08 standard deviations lower for Pakistani and Bangladeshi students exposed to Ramadan in early pregnancy. We argue these “intent to treat” estimates are downward biased relative to fasting’s effect due to…
A 5-year multicentre randomized controlled trial comparing personalized, frozen and fresh blastocyst transfer in IVF.
2020
Abstract Research question Does clinical performance of personalized embryo transfer (PET) guided by endometrial receptivity analysis (ERA) differ from frozen embryo transfer (FET) or fresh embryo transfer in infertile patients undergoing IVF? Design Multicentre, open-label randomized controlled trial; 458 patients aged 37 years or younger undergoing IVF with blastocyst transfer at first appointment were randomized to PET guided by ERA, FET or fresh embryo transfer in 16 reproductive clinics. Results Clinical outcomes by intention-to-treat analysis were comparable, but cumulative pregnancy rate was significantly higher in the PET (93.6%) compared with FET (79.7%) (P = 0.0005) and fresh embr…
Prospective, randomized, single-center trial comparing double-balloon enteroscopy and spiral enteroscopy in patients with suspected small-bowel disor…
2013
Background Double-balloon enteroscopy (DBE) is an established method in diagnostic and therapeutic small-bowel enteroscopy. Objective Spiral enteroscopy (SE) appears to be a promising new technique. A randomized, prospective study was conducted to compare both methods. Design Randomized, prospective study. Setting Single tertiary referral center. Patients Between September 2009 and March 2011, 26 patients with suspected mid-GI disorders completed the study. Interventions Patients were randomly assigned to DBE or SE. The oral examination was conducted first, with the deepest point reached being marked with India ink. An additional anal examination followed the day after, with the aim of reac…
Effect of aerobic exercise and diet on liver fat in pre-diabetic patients with non-alcoholic-fatty-liver-disease: A randomized controlled trial.
2017
AbstractThe study aimed to assess whether aerobic exercise (AEx) training and a fibre-enriched diet can reduce hepatic fat content (HFC) and increase glycaemic control in pre-diabetic patients with non-alcoholic fatty liver disease (NAFLD). Six-hundred-and-three patients from seven clinics in Yangpu district, Shanghai, China were recruited. Of them 115 individuals aged 50–65-year fulfilled the inclusion criteria (NAFLD with impaired fasting glucose or impaired glucose tolerance) and were randomly assigned into exercise (AEx n = 29), diet (Diet n = 28), exercise plus diet (AED n = 29), or no-intervention (NI n = 29) groups. Progressive supervised AEx training (60–75% VO2max intensity) was gi…

Rosiglitazone evaluated for cardiovascular outcomes in oral agent combination therapy for type 2 diabetes (RECORD): a multicentre, randomised, open-l…
2009
Udgivelsesdato: 2009-Jun-20 BACKGROUND: Rosiglitazone is an insulin sensitiser used in combination with metformin, a sulfonylurea, or both, for lowering blood glucose in people with type 2 diabetes. We assessed cardiovascular outcomes after addition of rosiglitazone to either metformin or sulfonylurea compared with the combination of the two over 5-7 years of follow-up. We also assessed comparative safety. METHODS: In a multicentre, open-label trial, 4447 patients with type 2 diabetes on metformin or sulfonylurea monotherapy with mean haemoglobin A(1c) (HbA(1c)) of 7.9% were randomly assigned to addition of rosiglitazone (n=2220) or to a combination of metformin and sulfonylurea (active con…

Comparative intention-to-treat analysis of the video-assisted thoracoscopic surgery approach to pulmonary segmentectomy for lung carcinoma
2015
Objectives To compare the video-assisted thoracoscopic surgery (VATS) with the open thoracotomy access to pulmonary segmentectomy by the clinical outcomes and long-term survival in lung carcinoma. Methods Non-randomized comparative intention-to-treat study of prospective institutional registry data and survival data of 100 consecutive patients undergoing segmentectomy. Results Within one decade (2002-12), 100 patients with proven or highly suspected lung carcinoma underwent 100 anatomical sub-lobar pulmonary resections (52 typical and 20 atypical segmentectomies, 28 split-lobe procedures). Fifty-six patients were operated by VATS and 44 by thoracotomy access. Comparison of demographic, medi…
