Telemedicine Online Visits in Urology During the COVID-19 Pandemic-Potential, Risk Factors, and Patients' Perspective.
2020
The current coronavirus disease 2019 (COVID-19) pandemic has placed considerable strain on hospital resources. We explored whether telemedicine (defined as a videoconference) might help. We undertook prospective structured phone interviews of urological patients (n = 399). We evaluated their suitability for telemedicine (judged by a panel of four physicians) and their risks from COVID-19 (10 factors for a poor outcome), and collected willingness for telemedicine and demographic data. Risk factors for an adverse outcome from COVID-19 infection were common (94.5% had one or more) and most patients (63.2%) were judged suitable for telemedicine. When asked, 84.7% of patients wished for a teleme…
A decade of trials of interferon-alpha for chronic hepatitis C. A meta-regression analysis
2003
The most relevant randomized controlled trials of interferon-alpha (IFN) for naive patients with chronic hepatitis C (CHC) published in a decade, just before appearance of pegylated IFN trials in 2000, were included in this paper. Its purpose is to review the relationship between sustained biochemical response in active versus control group versus usual clinical variables as IFN regimens, cirrhosis, genotype and versus less frequently addressed variables as funding, methodological quality or location of principal author. Meta-analysis estimates of global treatment effect varied according to trial design: group 1=IFN versus placebo/no treatment, 32 RCTs, 2499 pts, OR 9.5 (6.3-14.2); group 2a…
Home treatment of fragile patients with acute pulmonary embolism: a subgroup analysis of the multinational home treatment of pulmonary embolism (HoT-…
2020
Abstract Background and aims Subgroup analyses of randomized trials and cohort studies on direct oral anticoagulants (DOACs) suggested that single direct drug treatment may be effective and safe in elderly and “fragile” patients with acute pulmonary embolism (PE). In a post-hoc analysis of HoT-PE, a prospective multicenter management trial, we studied whether early discharge and home treatment of acute PE is effective and safe in these patients. Methods HoT-PE enrolled patients with acute PE classified as being at low risk based on the modified Hestia criteria and the absence of right ventricular dysfunction. The primary efficacy outcome was symptomatic recurrent VTE, or PE-related death wi…
EP1168 The influence of obesity on tumor recurrence in vulvar cancer patients
2019
Introduction/Background Obesity is associated with decrased survival in several cancer entities. The influence of obesity on prognosis of vulvar cancer patients is not clear. However, knowledge about this may have consequences on treatment and follow-up. Methodology This is an analysis of the large AGO-CaRE-1 study which included vulvar cancer patients (UICC stage IB and higher), treated in 29 cancer centers between 1998 and 2008, in order to analyze treatment patterns and prognostic factors. Results In total, 849 eligible patients were divided into two groups depending on their body mass index (BMI, 0.05). Radical vulvectomies were performed more frequently in patients having a BMI ≥30 kg/…
Frovatriptan vs almotriptan for treatment of menstrual migraine: a double-blind, randomized, cross-over, multicenter Italian study
2013
Results 67 of the 96 female patients of the intention-to-treat population of the main study had regular menstrual cycles and were thus included in this subgroup analysis. 77 migraine attacks classified as related to menses were treated with frovatriptan and 78 with almotriptan. Rate of pain relief at 2and 4-hrs was 36% and 53% for frovatriptan and 41% and 50% for almotriptan (p=NS between treatments). Rate of pain free at 2and 4-hrs was 19% and 47% with frovatriptan and 29% and 54% for almotriptan (p=NS). At 24-hrs, 62% of frovatriptanand 67% of almotriptan-treated patients had pain relief, while 60% vs. 67% were pain free (p=NS). Recurrence at 24-hrs was significantly (p<0.05) lower with f…
Use of statins and the risk of dementia and mild cognitive impairment: a systematic review and meta-analysis
2018
AbstractWe conducted a systematic review and meta-analysis to investigate whether the use of statins could be associated with the risk of all-caused dementia, Alzheimer’s disease (AD), vascular dementia (VaD), and mild cognitive impairment (MCI). Major electronic databases were searched until December 27th, 2017 for studies investigating use of statins and incident cognitive decline in adults. Random-effects meta-analyses calculating relative risks (RRs) were conducted to synthesize effect sizes of individual studies. Twenty-five studies met eligibility criteria. Use of statins was significantly associated with a reduced risk of all-caused dementia (k = 16 studies, adjusted RR (aRR) = 0.849…
An FFR CT diagnostic strategy versus usual care in patients with suspected coronary artery disease planned for invasive coronary angiography at Germa…
2017
Aim Diagnostic evaluation practices for suspected coronary artery disease (CAD) may vary between countries. Our objective was to compare a CT-derived fractional flow reserve (FFRCT) diagnostic strategy with usual care in patients with planned invasive coronary angiography (ICA) enrolled in the PLATFORM (Prospective Longitudinal Trial of FFRCT: Outcome and Resource Impacts) study at German sites. Methods Patients were divided into two consecutive observational cohorts, receiving either usual care or CT angiography (CTA)/FFRCT. The primary endpoint was the percentage of patients planned for ICA, with no obstructive CAD on ICA within 90 days. Secondary endpoints included death, myocardial infa…
AB0210 Quality of Life Indexes in Patients with Very Early Rheumatoid Arthritis (VERA): A Two Center Subgroup Analysis from The Adapthera Cohort: Tab…
2016
Background The significance of early diagnosis and early therapy initiation in patients with RA is tremendous. ADAPTHERA is a state wide rheumatology network based in Rhineland-Palatinate, Germany. ADAPTHERA aims to improve RA prognosis and quality of patients` life by reducing the time-to-RA-diagnosis. While there have been a lot of studies regarding quality of life in patients with established RA 1,2 , adequate data concerning very early rheumatoid arthritis (VERA) (disease duration Objectives To study quality of life in VERA patients and to investigate its associations with various RA associated clinical and laboratory parameters. Methods In a two center subgroup analysis from the ADAPTH…
Palliative splenic irradiation in primary and post PV/ET myelofibrosis: outcomes and toxicity of three radiation schedules
2009
Splenectomy and splenic irradiation (SI) are the sole treatment modalities to control drug resistant splenomegaly in patients with myelofibrosis (MF). SI has been used in poor surgical candidates but optimal total dose and fractionation are unclear. We retrospectively reviewed 14 MF patients with symptomatic splenomegaly. Patients received a median of 10 fractions in two weeks. Fraction size ranged from 0.2–1.4 Gy, and total dose varied from 2–10.8 Gy per RT course. Overall results indicate that 81.8% of radiation courses achieved a significant spleen reduction. Splenic pain relief and gastrointestinal symptoms reduction were obtained in 94% and 91% of courses, respectively. Severe cytopeni…
