Changes in dietary pattern in 15 year old adolescents following a 4 month dietary intervention with school breakfast – a pilot study
2006
Abstract Background Few studies on impact of meals served in school have been published. However, implications of school meals are an actual issue of both public and political concern in several countries. The objective of this study was to evaluate if breakfast served in a lower secondary school could improve dietary habits and school performance among the students. Methods All students in 10th grade in a lower secondary school, consisting of two school classes, were invited to participate in a controlled study. The students in one class were offered a free breakfast at the beginning of each school day for 4 months, while the students in the second class were controls. Both classes were ed…
Evidence on the effectiveness of occupational health interventions.
2006
Background At present there exists no overview of the range of evidence currently available regarding the effectiveness of occupational health interventions (OHI). Methods Articles published in 2000 and 2001 in 16 general and specialized biomedical journals were searched for evaluations of OHI studies. Results Out of 8,687 articles searched there were 148 OHI studies. In 21% of the studies the study design was a randomized controlled trial, in 28% it was a controlled trial, an interrupted time-series in 7% and a different design in 44%.

Effects of a group-based exercise program on the mood state of frail older women after discharge from hospital
2002
Background Older people with somatic illnesses are at increased risk of depression. It is not known whether exercise alleviates depressive symptoms in frail, very old people recuperating from an acute illness. Objective To determine the effects of a group-based exercise training program on mood. Methods Sixty-eight women (mean age 83.0, SD 3.9 years) who were hospitalized due to an acute illness, and were mobility impaired at admission, were randomized into group-based 10-week strength training intervention (N=34) and home exercise control (N=34) groups. Twenty-four women in the training and 28 in the control group completed the follow-up. Measures of mood state with the Zung Self-Rating De…
Low-Dose Aspirin Use and Cognitive Function in Older Age: A Systematic Review and Meta-analysis
2017
Objectives:\ud \ud To investigate whether low-dose aspirin (<300 mg/d) can influence the onset of cognitive impairment or dementia in observational studies and improve cognitive test scores in randomized controlled trials (RCTs) in participants without dementia.\ud \ud Design:\ud \ud Systematic review and meta-analysis.\ud \ud Setting:\ud \ud Observational and interventional studies.\ud \ud Participants:\ud \ud Individuals with no dementia or cognitive impairment initially.\ud \ud Measurements:\ud \ud Odds ratios (ORs) and 95% confidence intervals (CIs), adjusted for the maximum number of covariates from each study, were used to summarize data on the incidence of dementia and cognitive impa…
Dance movement therapy and falls prevention
2017
Falls are a leading cause of morbidity, healthcare use and mortality. Dance is a popular form of physical activity among older people and previous research has suggested that it may improve various health outcomes in this population, including balance, gait and muscle performance. A systematic review of the potential benefits of dance on falls and fear of falling is lacking. Thus, we conducted a systematic review considering all randomized controls trials (RCTs) investigating if dance can reduce falls and improve fear of falling in older adults. Major databases were searched from inception until 1 March 2017 and a total of 10 RCTs were identified, which included a total of 680 people (n = 3…
Transforming Obesity Prevention for CHILDren (TOPCHILD) Collaboration: protocol for a systematic review with individual participant data meta-analysi…
2022
ABSTRACTIntroductionBehavioural interventions in early life appear to show some effect in reducing childhood overweight and obesity. However, uncertainty remains regarding their overall effectiveness, and whether effectiveness differs among key subgroups. These evidence gaps have prompted an increase in very early childhood obesity prevention trials worldwide. Combining the individual participant data (IPD) from these trials will enhance statistical power to determine overall effectiveness and enable examination of intervention-covariate interactions. We present a protocol for a systematic review with IPD meta-analysis to evaluate the effectiveness of obesity prevention interventions commen…
Root coverage with connective tissue graft associated with coronally advanced flap or tunnel technique: a randomized, double-blind, mono-centre clini…
2016
Aim: The aim of this randomized clinical trial was to compare the coronally advanced flap (CAF) with the modified microsurgical tunnel technique (MMTT) for treatment of Miller class I and II recessions. Material and Methods: Forty patients with 71 gingival recessions were recruited and randomly assigned to either CAF or to MMTT. In both groups, a connective tissue graft was applied. Clinical evaluations were performed after 3, 6, and 12 months. Impressions were taken and digitally scanned three-dimensionally to evaluate the quantitative soft tissue changes in the operative region. Patient satisfaction was measured with the root coverage aesthetic score (RES). Results: After a period of 12 m…
Exact simulation of first exit times for one-dimensional diffusion processes
2019
International audience; The simulation of exit times for diffusion processes is a challenging task since it concerns many applications in different fields like mathematical finance, neuroscience, reliability horizontal ellipsis The usual procedure is to use discretization schemes which unfortunately introduce some error in the target distribution. Our aim is to present a new algorithm which simulates exactly the exit time for one-dimensional diffusions. This acceptance-rejection algorithm requires to simulate exactly the exit time of the Brownian motion on one side and the Brownian position at a given time, constrained not to have exit before, on the other side. Crucial tools in this study …
Possible synergic action of non-steroidal anti-inflammatory drugs and glucosamine sulfate for the treatment of knee osteoarthritis: a scoping review
2022
Abstract Background Several studies have reported that glucosamine sulfate (GS) can improve knee osteoarthritis (OA) symptomatology. In parallel, the disease-modifying effects of non-steroidal anti-inflammatory drugs (NSAIDs) in knee OA have also been investigated. However, limited literature has reported the combined effect of GS and NSAIDs. The aim of this scoping review is to describe the scope and volume of the literature investigating the potential benefits and synergistic effect of a combination of GS and NSAIDs in patients with knee OA. Methods PubMed and Embase were searched for studies published from inception through April 2022, evaluating the effects of the combination of GS and …
Clinical Evaluation of self and professionally applied desensitizing agents in relieving dentin hypersensitivity after a single topical application: …
2013
Objectives: The objective of this study is to evaluate the efficacy of self and professionally applied desensitizing agents in relieving dentinal hypersensitivity after single direct topical application. Study Design: This was a randomized controlled trial conducted among 57 patients. 8% Arginine paste was self- applied by the subject and Gluma desensitizer was applied by investigator. Numeric rating scale was used to mea - sure hypersensitivity after tactile stimulus, Schiff scale was used for cold and air blast stimuli respectively. Scores were recorded at baseline, immediately, 15 and 30 days after the application. Friedman, Wilcoxon test as post hoc was used to analyze within group diff…
