Filter by:The purpose of this study is to examine hypoxic vasodilation and the role of beta-adrenergic receptors in younger premenopausal, perimenopausal, and older postmenopausal women.
The goal of this observational study is to develop online, self-paced mindfulness (iMBSR) and lifestyle education (iLifeEd) programs for adults with cognitive concerns. Participants will engage in focus groups to discuss healthy living, web-based behavioral interventions, intervention content/format and ideal outcomes after engaging in behavioral interventions that promote healthy living. Additionally, participants will provide feedback on the protocol and online platform for either iMBSR or iLifeEd. This feedback will be used to refine the iMBSR and iLifeEd protocols for future use in the randomized controlled trial portion of the parent project.
Abstract: The purpose of this pilot study is to examine the effect and feasibility of a Nordic walking group training intervention on the physical and mental health of older adults evacuated from their homes to Haifa. Participants: The study will include 31 participants aged 65 and over who are in stable health and have been cleared by their physician to participate in this NW program. Intervention: The intervention will consist of two 60-minute Nordic walking (NW) sessions per week for two months, 16 sessions in total. Participants will be provided with walking sticks to use during the sessions. The sessions will be led by certified health professionals (PT, RN), assisted by trained undergraduate and graduate physiotherapy students. Outcomes: The primary outcome will be endurance to the walking sessions, and average weekly and monthly number of steps, measured by a smartphone application. Secondary outcomes will include three physical tests: 30-second sit-to-stand test, 4-meter walk test and heel raise test. mental health (PHQ-9 depression scale, GAD-7 anxiety scale, WHOQOL- BREF quality of life scale, PANAS short form positive and negative affect scale), and perceived global effect of the intervention. Design: The study will use a single-group pre-test/post-test design. Participants will be assessed at baseline, after two months of intervention, and at six months follow-up. Data Analysis: Data will be analyzed using descriptive statistics and mixed-effects linear regression models. Significance: This pilot study will provide valuable information on the feasibility and effect of this group NW intervention for older adults evacuated from their homes. The findings will be used to plan and design a larger longitudinal RCT.
The investigators propose a pilot randomized trial to gather preliminary data to test the hypothesis that Fisetin will reduce abundance of senescent cells in blood, skeletal muscle, and both subcutaneous and inter muscular adipose tissue and improve 6-minute walk distance in 34 people with PAD. the investigators will determine whether greater declines in abundance of cells with senescent markers are associated with greater improvement in 6-minute walk distance in people with PAD. In exploratory analyses, the investigators will assess whether Fisetin reduces SASP and novel senescent markers in adipose tissue, muscle, and/or blood.
This randomized, double blind, placebo controlled clinical trial will test the efficacy of a probiotic/prebiotic combination ("synbiotic") on the skeleton in older women.
The Early Oral Aging Syndrome (EOAS) is a broad concept concerning changes in oral health caused by systemic diseases of different origins, which are related to the current lifestyle in the pediatric population. Enamel defects associated with intrinsic and extrinsic factors promote the acceleration of dental structure loss in an early manner, causing impairment of function, aesthetics, and quality of life. In this context, this study aims to identify the prevalence of early childhood tooth wear and its severity using the Early Childhood Oral Aging Syndrome (EOAS) index as a diagnostic and epidemiological survey instrument, considering current alterations found in the pediatric population and verifying possible factors associated with each severity level. Participants aged 3 to 6 years old, enrolled in the pediatric dentistry clinic of the University Nove de Julho, will be selected. Children with imperfect amelogenesis and dentinogenesis, genetic syndromes, and undergoing orthodontic treatment will be excluded from the research. A questionnaire on general health, sleep quality, nutrition, hygiene habits, and parafunctional habits will be administered. Subsequently, a clinical examination will be conducted using the new Early Childhood Oral Aging Syndrome (EOAS) index with scores ranging from 0 to 3 to assess dental wear and dental management, and scores I to III that should be used concomitantly in cases of enamel defects presence, in addition to measuring the Vertical Dimension of Occlusion (VDO). EOAS scores will be computed and statistically analyzed for deciduous dentition with a significance level of P<0.05.
Background: Tai Chi Chuan, a Chinese martial art style, is a mind-body modality that has shown positive impacts on health markers in various populations, particularly older adults. This study aims to investigate the effects of a 12-week program of Tai Chi Chuan exercises based on the Yang 16-movement form and walking on older adults' physical and mental markers. Methods: This study is a randomized, single-blinded, two-arm, parallel, superiority trial. Forty older adults between 60 and 75 years old who are not engaged in any systematic strength and aerobic training program will be recruited. Candidates with language and cognitive problems, a history of cardiovascular diseases (except controlled hypertension), osteoarticular limitations and fractures, severe injuries, and prosthetic placement in the last six months will be excluded. Participants will be randomly allocated on a 1:1 ratio to a 12-week intervention with Tai Chi Chuan and walking two times per week, or an active-control group with walking two times per week. Physical measures will be muscle strength (i.e., knee extensors maximum strength and lower limbs functional performance -primary outcomes-, dynamic knee extensors endurance, handgrip strength, back-leg-chest strength), functional capacity, static balance, muscle thickness and muscle quality of quadriceps. Mental measures will be quality of life, sleep quality, cognitive function, and depressive and anxiety symptoms. Outcomes will be measured before and after 12 weeks of intervention. The analysis plan will use an intention-to-treat approach and protocol criteria. Discussion: The conceptual hypothesis is that the intervention training program with Tai Chi Chuan and walking will lead to greater improvements in both physical and mental parameters due to its multi-component character compared to the walking active-control group.
Premature, non-physiological tooth wear in childhood has numerous repercussions for oral health. This is a growing problem with multifactorial causes and associated with the current lifestyle. The aim of the present study was the development and determination of content validity of the Childhood Early Oral Aging Syndrome (CEOAS) index for the primary dentition as a diagnostic and epidemiological survey tool considering the current changes found in this population.
This is a randomized, controlled, double-blinded, within-subject (split-face), multicenter, prospective study to investigate whether RHA® Redensity with new anesthetic agent is non-inferior to RHA® Redensity with lidocaine in terms of injection site pain felt by the subject during injection. At screening, the Principal Investigator (PI) evaluated subjects' perioral rhytid severity (using the Perioral Rhytid Severity Rating Scale; PR-SRS) to confirm eligibility and to establish a pre-treatment score for assessing aesthetic improvement. At Visit 1, RHA® Redensity with new anesthetic agent was administered in a random sequence (first or second injection) and side of the mouth (left or right) and RHA® Redensity with lidocaine was administered to the other side. Study subjects and the PI injecting study devices were blinded. Immediately after injection of an upper perioral quadrant, subjects rated the injection site pain experienced during injection using a 100 mm Visual Analog Scale (VAS). Injection site pain in each side of the mouth was also assessed at 15, 30, 45 and 60 minutes after injection of the upper quadrant. Safety evaluation consisted of AE assessments, a 30-day CTR (Common Treatment Response) diary and a follow-up call performed by the study site at 72 hours after injection. Subjects attended Visit 2 (30 days post-injection) where effectiveness and safety assessments were conducted. Subjects who presented with an unresolved clinically significant device related AE at Visit 2 received a optional follow-up phone call no later than 30 days after Visit 2. If the clinically significant AE remained unresolved, the Investigator requested that the subject attended the optional in-clinic follow-up visit (i.e., Visit 3) within 5 working days. Follow-up of the clinically significant AE continued until the AE was resolved or the TI determines that additional follow-up was not necessary.
The overarching hypothesis to be evaluated using this protocol is that age-related hearing loss (ARHL) leads to shifts in the functional spatial boundaries between segregated and integrated auditory streams, and that hearing aid intervention that relies on directional processing schemes is most effective for those that have the poorest spatial sensitivity. One key component of the research design is to measure both behavioral and neurophysiological indices of an individual's spatial segregation boundary. The second key component is to measure the cost or benefit associated with hearing aid intervention in older hearing-impaired listeners. The final component is to relate cost and benefit of hearing aid intervention to spatial sensitivity measures that might predict the efficacy of clinical intervention.
