Root Canal Morphology and Configuration of the Mandibular Canine: A Systematic Review

2021

The aim of this study was to systematically review the root canal morphology and configuration (RCC) of mandibular canines (MaCa). The review was registered in the PROSPERO database (ID-272297) and it was carried out following the PRISMA guidelines. Three electronic databases (MEDLINE via PubMed, Embase, Scopus) were searched. Randomized controlled trials, cross-sectional, cohort, comparative, evaluation and validation studies have been included. The anatomical quality assessment (AQUA) tool was used for a quality assessment of the anatomical studies. Of 910 studies retrieved from the systematic search, 28 studies investigating RCCs were included. Most MaCa were single-rooted (87.9–100%), w…

Charting a Roadmap for Heart Failure Biomarker Studies

2013

Heart failure is a syndrome with a pathophysiological basis that can be traced to dysfunction in several interconnected molecular pathways. Identification of biomarkers of heart failure that allow measurement of the disease on a molecular level has resulted in enthusiasm for their use in prognostication and selection of appropriate therapies. However, despite considerable amounts of information available on numerous biomarkers, inconsistent research methodologies and lack of clinical correlations have made bench-to-bedside translations rare and left the literature with countless publications of varied quality. There is a need for a systematic and collaborative approach aimed at definitively…

Interferon alfa for chronic hepatitis B infection: Increased efficacy of prolonged treatment

1999

Interferon alfa (IFN-alpha) is the primary treatment for chronic hepatitis B. The standard duration of IFN-alpha therapy is considered 16 weeks; however, the optimal treatment length is still poorly defined. We evaluated the efficacy and acceptability of prolonged IFN-alpha treatment in patients with chronic hepatitis B. To investigate whether treatment prolongation could enhance the rate of hepatitis B e antigen (HBeAg) seroconversion, we conducted a prospective, controlled, multicenter trial in which all patients were treated with a standard regimen of 10 million units IFN-alpha 3 times per week over 16 weeks. Patients who were still HBeAg-positive after 16 weeks of therapy were randomize…

EFFICACY AND SAFETY OF OZONE THERAPY FOR PATIENTS WITH CHRONIC HEPATITIS B: A MULTICENTER, RANDOMIZED CLINICAL TRIAL

2018

Background. Ozone therapy has a long history. Some studies proved that ozone therapy was useful in treatment of virus hepatitis. Objective: To evaluate the efficacy and safety of new medical ozone therapy system for the treatment of chronic hepatitis B. Method. One hundred eighty-nine patients with chronic hepatitis B were included in this open-label, phase 3 study, and randomly assigned to receive ozone autohemotherapy with experimental ozone generator TianYi (group 1) or with ozone generator Humares (group 2) or oral diammonium glycyrrhizinate capsules (group 3) in a 1:1:1 ratio for 12 weeks. The primary efficacy end point was sera HBV DNA level of less than 1×103 IU/ml or having a more t…

Phase 3 randomized study of adjuvant anastrozole (A), exemestane (E), or letrozole (L) with or without tamoxifen (T) in postmenopausal women with hor…

515 Background: Uncertainty still exists regarding the optimal schedule of adjuvant treatment of breast cancer with aromatase inhibitors (AI) and no trial has ever compared all the three AI. Methods: FATA-GIM3 is a multicenter, open label, 2x3 factorial phase 3 randomized study of adjuvant A, E and L upfront (UP - for 5 years) or sequentially (SEQ - for 3 years after 2 years of T) in postmenopausal HR breast cancer pts. Two comparisons were planned: UP vs SEQ and A vs E vs L. DFS (including local or distant relapse, second breast or non-breast cancer, DCIS and death, whichever came first) was the primary end-point; 2% at 5 yrs (corresponding to a HR of 0.79) was defined as the minimum diff…

Avoiding Bias in Observational Studies

2009

Background Many questions in human health research can only be answered with observational studies. In contrast to controlled experiments or well-planned, experimental randomized clinical trials, observational studies are subject to a number of potential problems that may bias their results.

Relaxation techniques in sports: A systematic review on acute effects on performance

2016

Abstract Objectives The aim was to provide an overview on the current state of research on acute effects of relaxation techniques in sports. Design A systematic review of randomized controlled trials was conducted. Methods PubMed, MEDLINE, PsycINFO, and SPORTDiscus were searched until August 2014. Additionally, reference lists of retrieved articles and relevant reviews were hand searched. To be included articles had to examine the effects of relaxation techniques on performance in sports. Furthermore, they had to be published in English, in a peer-reviewed journal, available full text online, and designed as either treatment outcome, clinical trial, and/or randomized controlled trial. The d…

Randomized controlled trial of the Valencia model of waking hypnosis plus CBT for pain, fatigue, and sleep management in patients with cancer and can…

2016

Background This study evaluated the efficacy of an intervention combining the Valencia model of waking hypnosis with cognitive-behavioral therapy (VMWH-CBT) in managing cancer-related pain, fatigue, and sleep problems in individuals with active cancer or who were post-treatment survivors. We hypothesized that four sessions of VMWH-CBT would result in greater improvement in participants' symptoms than four sessions of an education control intervention. Additionally, we examined the effects on several secondary outcome domains that are associated with increases in these symptoms (depression, pain interference, pain catastrophizing, and cancer treatment distress). Methods The study design was …

Cultural adaptation of the Smiling is Fun program for the treatment of depression in the Ecuadorian public health care system: A study protocol for a…

2021

Background Depression is one of the world's major health problems. Due to its high prevalence, it constitutes the first cause of disability among the Americas, where only a very low percentage of the population receives the adequate evidence-based psychological treatment. Internet-Based Interventions (IBIs) are a great alternative to reduce the treatment gap for mental disorders. Although there are several studies in low-and middle-income countries proving IBIs' feasibility and acceptability, there is still little evidence of the effectiveness in diverse social and cultural contexts such as Latin America. Methods Two studies will be described: Study 1 is focused on the cultural adaptation o…
