Deep sclerectomy versus trabeculectomy with low-dosage mitomycin C: four-year follow-up
2006
<i>Aims:</i> To compare the long-term effects of low-dosage mitomycin C (MMC) in both deep sclerectomy (DSMMC) and trabeculectomy (TPMMC) on intraocular pressure (IOP). <i>Methods:</i> Analysis of extended follow-up of data from a prospective clinical trial. Forty patients were originally randomised to undergo either DSMMC (19 eyes) or TPMMC (21 eyes). Follow-up was performed at postoperative day 1, weeks 1, 2 and 3, as well as months 1, 3, 6, 9, 12, 18, 24, 36 and 48. Two- to three-week data were not included in the statistical analysis. Postoperative complications, number of antiglaucoma medications and IOP were recorded at each visit. Complete (no medications) and…
Lifestyle Changes for the Treatment of Nonalcoholic Fatty Liver Disease - A 2015-19 Update.
2020
Background: Lifestyle interventions aimed at weight loss have been associated with improved liver enzymes, reduced intrahepatic triglyceride content, and improved histology (including reduced fibrosis stage). Objective: To revise the evidence on the beneficial effects of lifestyle changes accumulated since 2015, following the publication of the pivotal Cuban experience with histologic outcome. Methods: A PubMed search covering the period 2015 to July 2019 was carried out. All retrieved references were analyzed and double-checked by authors. Results: 20 new studies were identified; in addition, two relevant studies provided new evidence. Thirteen studies were classified as randomized, contr…
What is the effect of physical activity on duration and mode of delivery? Secondary analysis from the Norwegian Fit for Delivery trial
2018
Introduction: The beneficial effects of physical activity during pregnancy for the mother and offspring have been reported by several studies but there are conflicting results concerning the possible effect of physical activity on the course of labor and risk of cesarean delivery. This study presents secondary analyses from the Norwegian Fit for Delivery randomized controlled trial, aiming at studying the effect of a lifestyle intervention including group exercise classes, as well as the possible influence of physical activity level in late pregnancy, on labor outcomes. Material and methods: Healthy nulliparous women with singleton pregnancy were randomized to an intervention group, n = 303…
Cycle scheduling for in vitro fertilization with oral contraceptive pills versus oral estradiol valerate: a randomized, controlled trial
2013
Abstract Background Both oral contraceptive pills (OCPs) and estradiol (E2) valerate have been used to schedule gonadotropin-releasing hormone (GnRH) antagonist in vitro fertilization (IVF) cycles and, consequently, laboratory activities. However, there are no studies comparing treatment outcomes directly between these two pretreatment methods. This randomized controlled trial was aimed at finding differences in ongoing pregnancy rates between GnRH antagonist IVF cycles scheduled with OCPs or E2 valerate. Methods Between January and May 2012, one hundred consecutive patients (nonobese, regularly cycling women 18–38 years with normal day 3 hormone levels and <3 previous IVF/ICSI attempts)…
Combination of omalizumab and specific immunotherapy is superior to immunotherapy in patients with seasonal allergic rhinoconjunctivitis and co-morbi…
2008
Summary Background The treatment of allergic asthma by specific immunotherapy (SIT) is hampered by potential side-effects. Objective The aim of this study was to study the effect of omalizumab, a monoclonal anti-IgE antibody, in combination with SIT in patients with seasonal allergic rhinoconjunctivitis (SAR) and co-morbid seasonal allergic asthma (SAA) incompletely controlled by conventional pharmacotherapy. Methods A randomized, double-blind, placebo-controlled, multi-centre trial was performed to assess the efficacy and safety of omalizumab (Xolair®) vs. placebo in combination with depigmented SIT (Depigoid®) during the grass pollen season. Omalizumab or placebo was started 2 weeks befor…
Economic evaluation of caspofungin vs liposomal amphotericin B for empirical therapy of suspected systemic fungal infection in the German hospital se…
2007
As antifungal agents are frequently used in hematology and oncology, economic data on the empirical therapy of suspected systemic fungal infection are pivotal. Data were analyzed according to: (1) the rate of nephrotoxicity related to treatment with caspofungin in comparison to liposomal amphotericin B (L-AmB) from a randomized clinical trial, (2) the effect of nephrotoxicity on length of hospital stay from a European observational study, and (3) an example of total bottom-up cost in a department of hematology in Germany. All estimates include 95% confidence intervals (CI) using two-stage Monte Carlo simulation on binominal and Gaussian random variables from separate studies with comparable…
Dissection of DLBCL microenvironment provides a gene expression-based predictor of survival applicable to formalin-fixed paraffin-embedded tissue
2018
Abstract Background Gene expression profiling (GEP) studies recognized a prognostic role for tumor microenvironment (TME) in diffuse large B-cell lymphoma (DLBCL), but the routinely adoption of prognostic stromal signatures remains limited. Patients and methods Here, we applied the computational method CIBERSORT to generate a 1028-gene matrix incorporating signatures of 17 immune and stromal cytotypes. Then, we carried out a deconvolution on publicly available GEP data of 482 untreated DLBCLs to reveal associations between clinical outcomes and proportions of putative tumor-infiltrating cell types. Forty-five genes related to peculiar prognostic cytotypes were selected and their expression …
Evidence on the effects of exercise therapy in the treatment of chronic disease
2009
Evidence on the effects of exercise in the treatment of patients with chronic diseases should be based on well designed randomised controlled trials. The most consistent finding of the meta-analyses summarised in the present work is that aerobic/functional capacity and muscle strength can be improved by exercise training among patients with different diseases without having detrimental effects on disease progression. This is important, as with population aging exercise therapy may be an important means of reducing disability and increasing the number of older people living independently. Additionally, there is accumulating evidence that in patients with chronic disease exercise therapy is e…
Risk Factors for Rate of Relapse and Effects of Steroid Maintenance Therapy in Patients With Autoimmune Pancreatitis: Systematic Review and Meta-anal…
2019
Background & Aims: Risk for relapse after induction of remission with steroid therapy has been studied extensively in patients with autoimmune pancreatitis (AIP), but findings have been equivocal. We performed a systematic review and meta-analysis to estimate the relapse rate of AIP after initial remission after steroid treatment and to identify factors associated with relapse. Methods: Three reviewers searched MEDLINE, SCOPUS, and EMBASE until July 2018 to identify studies on rate of relapse of AIP after induction of remission with steroid therapy. A pooled estimate was calculated using the DerSimonian and Laird method for a random-effects model. This study was conducted in accordance …
Antifungal agents for preventing fungal infections in non-neutropenic critically ill patients
2016
Background Invasive fungal infections are important causes of morbidity and mortality among critically ill patients. Early institution of antifungal therapy is pivotal for mortality reduction. Starting a targeted antifungal therapy after culture positivity and fungi identification requires a long time. Therefore, alternative strategies (globally defined as 'untargeted antifungal treatments') for antifungal therapy institution in patients without proven microbiological evidence of fungal infections have been discussed by international guidelines. This review was originally published in 2006 and updated in 2016. This updated review provides additional evidence for the clinician dealing with s…
