Filter by:Physical inactivity is identified as one of the most important modifiable risk factors for chronic diseases, functional loss and disability and reliable assessment tools of physical activity are crucial in both research and clinical settings. Traditionally, physical activity and sedentary behavior have been primarily assessed with questionnaires. Recently, accelerometers have been widely used to measure physical activity, sedentary behavior and sleep patterns in ageing. Still, the diversity of brands and models, various assessment protocols (e.g. anatomic locations, sampling frequency), data processing and outcome measures have posed challenges to the interpretation and comparability of results across studies. Therefore, despite some limitations, questionnaires are still considered an important assessment method, especially in large-scale studies. In order to bridge the differences in the interpretation of data from questionnaires to accelerometers among older adults, there is a need to validate existing physical activity and sedentary behavior questionnaires with energy expenditure in this population. Energy expenditure has been used to "translate" accelerometer output into physiological outcomes. Nevertheless, several issues remain unresolved, including (1) limited calibration studies focusing on older adults; (2) resting metabolic rate and maximum physiological capacity typically decrease with aging, which makes daily activities "more intense" for an older person compared to a younger person; and (3) the same accelerometer metric measured at different body positions may be linked to completely different physiological outcomes. Such diverse physiological impact according to the anatomical placement of accelerometers requires a rigorous harmonization of metrics from the accelerometers with energy expenditure during representative activities at different intensities. The aims of this methodological study focusing on 80+ year-olds are to: 1. develop cut-points from accelerometers at different anatomical positions for different intensities of physical activity based on energy expenditure during semi-standardized daily tasks in the lab. 2. validate accelerometer at different anatomical positions against energy expenditure measured by double-labelled water (DLW) in free-living conditions. 3. validate existing physical activity and sedentary behavior questionnaires against DLW in free-living conditions.
Little is known about the natural course and prognosis factors of inpatients and outpatients with Disruptive Mood Dysregulation Disorder (DMDD). The investigators conducted a cross-sectional study to determine the evolution of a sample of DMDD patients referred to the hospital for suicidal behaviors between 2013 and 2018 in terms of diagnostic stability, psychiatric comorbidity, and psychosocial factors. A group of patients with various episodic mood disturbances was used as a clinical case control group. In addition to change in DMDD symptoms across time, the investigators examined the onset and persistence of psychiatric comorbidity using the KIDDIE-SADS PL and suicidal behaviors using the Colombia Suicidality Severity Rating Scale. The investigators also examined the persistence of depressive symptoms using the Beck Depression Inventory (BDI-II), the persistence of emotional lability (Affective Lability Scale-18), borderline traits (Abbreviated Diagnostic of Inventory Borderline). Socio-demographic, clinical features and actigraphy-measured sleep characteristics determined between 2013 and 2018 were used to predict the evolution of the DMDD patients and the clinical control group.
There is a debate in the literature about the effect of NSLBP on pelvic tilt and its effect on balance, sensory integration and functional disability so we need this study to fill the aforementioned gap in literature in this field. So the purpose of the study is to evaluate posterior pelvic tilt effect on overall dynamic balance, sensory integration and functional disability in patients with non-specific low back pain.
The pelvic floor serves as stability and support as it is the postural balance and core resource base for the pelvic organs. A dysfunction in the organs in this area can affect the pelvic floor muscles, the functioning of an organs in the muscles. Incontinence organ prolapse, pelvic pain and sexual problems may occur when the support or stability of the pelvic floor is impaired. Pelvic floor novelization is not always seen weakness. Sometimes excessive contractions and excessive activity in muscle tone can be seen. Stress and anxiety-related tension are the main causes of pelvic floor dysfunctions. Involuntary contractions and excessive muscle tone in the pelvic floor muscles cause chronic pelvic pain syndrome, constipation and dyssynergic defecation problems. Some of these patients have complaints of tightening teeth in the temporamandibular joint, grinding teeth at night, together with contractions in the pelvic floor. The aim of this study is to investigate the effect of pelvic floor improvement on tinnitus level as a result of dysfunctional condition in temporamandibular joint with treatment practices of pelvic floor patients with excessive muscle activity.
The aim of our study is to examine the effect of social isolation on physical activity level, health literacy and kinesophobia in heart rhythm disorders.
Use of proton pump inhibitors (PPI) has increased in recent years. There are concerns that PPIs have possible negative effects on bone metabolism. It has been suggested that PPIs may reduce the absorption of calcium from the small intestine and lead to bone resorption by affecting osteoclastic activity. In this study, it is planned to investigate the effects of lansoprazole, a proton pump inhibitor, on bone turnover markers in pediatric patients with gastroesophageal reflux or gastroesophageal reflux disease.
This study evaluates the effectiveness of two types of therapy for the treatment of sexual abuse psychological impact on a sample of Spanish women. The participants will receive first Trauma-Focused Cognitive Behavioral Therapy and Eye Movement Desensitization and Reprocessing treatments in order to observe the impact on symptoms of Posttraumatic Stress Disorder, somatization, obsessive-compulsive symptoms, anxiety, aggressiveness and dissociate symptoms.
The COVID-19 pandemic has resulted in several challenges in service delivery for the eating disorders program at McMaster Children's Hospital. Long waiting lists prior to the pandemic (6-9 month wait time) have been made worse by an interruption in service during the initial stages of the pandemic. New routine assessments were placed on hold for many months, while only the most urgently ill children were seen. This, in combination with a dramatic increase in new referrals has resulted in a long waitlist. Now families are waiting 12-18 months for service. The resulting waitlist is now unmanageable and unsafe. Investigators wish to study the implementation of a waitlist intervention which will educate parents on how to start to renourish their children and interrupt eating disordered behaviors. The intervention will consist of a series of educational videos and a book on how to help their children. It is hoped that this intervention can lessen the need for hospitalization and can change the trajectory of symptoms while waiting for service. A clinical care pathway will also be developed to ensure those waiting receive the most appropriate treatment.
The objectives of this study are to characterize the disease impact, the disease management and resource utilization, and provide benefits to the LC-FAOD community, by use of a convenient online platform for participants (or caregivers) to self-report information.
The objective of this prospective observational cohort study is to answer the following clinically important questions: 1. In patients with a pre-operative history of ICBs, what is the likelihood of improvement or deterioration in ICBs post-operatively? 2. What is the risk of developing post-operative de novo ICBs after Subthalamic Nucleus DBS (STN DBS)? 3. Which factors are important in predicting changes in ICBs after STN DBS? 4. What is the impact of ICBs on carer's quality of life QoL and burden?
