Filter by:Accidental falls in older adults are one of the world's major pubic health problem, because of their strong association with injuries and mortality rates. In Quebec, falls are responsible for a high rate of hospitalization (more than 1800 emergency department visits every day) and deaths (more than 10,000 in recent years). Preventing falls is therefore a key mission for health professionals. This research program aims to develop a new clinical approach to the rehabilitation management of the older with a neuro-musculoskeletal disorder and a risk of falling. This program is part of a new partnership project between UQAC and specialized geriatric services at the CIUSSS Saguenay-Lac-St-Jean (La Baie site). These geriatric services admit more than 400 new patients per year, representing a large pool of participants for the new program's development. Specifically, this program has 4 phases: 1) Create a clinical profile of patients in rehabilitation care from specialized geriatric services (ex: reasons for consultation, neuro-musculoskeletal disorders, rates and causes of falls, etc.); 2) to diagnose functional deficits of these patients on different dimensions of functional and physical evaluations, using standardized tests and high-tech instruments (ex: platform of force); 3) determine the effectiveness of a new exercise intervention program (OTAGO) for falls prevention; and 4) Measure client and professional team satisfaction as well as long-term impact of this new approach used to prevent falls. The most significant impact of this new program will be to reduce public health expenditure for care of older adults with balance disorder and risk for falls; and therefore, be implanted in other CIUSSS institutions from Quebec.
Foot pain is common in the general population. Plantar fasciopathy may affect 7% of the population at some time in their lives, but the incidence increases with age. This plantar problem is characterized by severe pain under the foot (at plantar level), which can be very incapacitating and disabling. This can lead to absenteeism from work, particularly for employees working in a standing posture. Various therapeutic avenues can be used to reduce pain and improve functionality, such as physiotherapy, infiltrations and surgery. In this research project, the propose the use of a conservative approach through the use of foot orthoses, which appears to be effective in reducing pain. The aim of the study is thus to better understand the effect of foot orthoses on postural balance and walking in workers with plantar fasciopathy. Participants will be assessed at baseline and eight weeks later to observe measured changes and clinical improvements following orthotic wear. Balance and gait pattern will be assessed using technological tools that have been validated in this respect. Participants will also be asked about their pain intensity. The hypothesis is that wearing the orthosis will improve the participants' balance and walking abilities, as well as reduce the level or intensity of their pain. In addition, this study could have an impact on the rate of absenteeism from work from current context of labour shortages.
The brain is constantly active and energetically expensive, making up a quarter of the body's energy budget despite occupying only 2% of its mass. To fuel this incessant activity, the brain relies on glucose, which accommodates 99% of its metabolic needs. In most cases, glucose is the ideal fuel since it is in constant surplus owing to 24-hr access to sugar-rich food. However, the brain is metabolically flexible and capable of metabolizing alternative fuels when glucose is scarce, or, decreasing rapidly. For example, during fasting when glucose stores are dwindling, ketone bodies can supplement the brain's metabolic needs. During intense exercise, when glucose stores are being rapidly depleted, lactate - a byproduct of this glucose turnover - similarly acts as an alternative fuel for the brain. In healthy individuals, exploiting this 'brain metabolic flexibility' may be beneficial in protecting the brain from aging. The main question is: Does the brain substrate switch that occurs during fasting and high-intensity exercise underlie the beneficial effects on the brain? Young, healthy participants will fast for 3 days and complete high-intensity cycling exercise, each of which will induce a brain substrate switch. Participants will also be passively infused with ketones (to simulate fasting) and lactate (to simulate high-intensity exercise) in the fed and rested state. In doing so, the investigators will isolate the brain substrate switch from the broader, pluripotent stressors that encompass fasting and exercise. The main outcome variables are the brain biomarkers: brain-derived neurotrophic factor (BDNF) and secreted amyloid beta precursor protein (sAPPA).
The objective of this study is to determine the efficacy of seven different formulations currently marketed and commercially available cosmetic products on skin tone evenness, post-inflammatory hyperpigmentation, and discrete pigmentation in females of Fitzpatrick skin types IV-VI.
