Filter by:Cerebellar ataxia (CA) is a collection of signs and symptoms caused by cerebellar dysfunction, which can be the result of different disease processes including hereditary and acquired conditions. High incidence of falls is reported in people with CA due to poor balance while walking. Therefore, it is crucial to assess the balance of people with CA to identify potential fallers. There are some clinical tests commonly used for assessing the balance of people with CA, including both generic measures of balance and ataxia-specific rating scales. The current best balance outcome measures for CA includes Berg Balance Scale (BBS), Timed Up and Go test (TUG), and the balance related items in Scale for the assessment and rating of ataxia (SARA). TUG is commonly used in clinical settings for the assessment of mobility and fall risk of individuals. However, a study done by Winser et. al (2017) found that the correlation between TUG and ataxia rating scales (SARA and ICARS) is only moderate. This indicates that the gait speed and functional mobility findings of TUG might not truly reflect the balance deficits of CA. Therefore, our study will develop a modified TUG for the assessment of balance in people with CA. Circular TUG (cTUG) is a modified version of the standard TUG. cTUG is an equilibrium test that challenges subjects' ability to maintain balance in response to the constant change in direction of walking. In cTUG, the subject walks a semi-circular pathway instead of a straight line. Walking in a circular pathway targets at challenging the coordination of people with CA as walking in a circle requires constant change in directions and correction after feedback. It is speculated that the cTUG will have better accuracy in predicting the balance and falls risk among people with CA. We will target at recruiting 30 healthy volunteers and 30 individuals with cerebellar ataxia. Besides the cTUG we will also assess disease severity of ataxia using the Scale for the Assessment and Rating of Ataxia (SARA), balance using the Berg Balance Scale, Timed Up and Go test, Sensory Organization test, Limits of Stability test and functional independence using the Barthel Index. For validation of the cTUG, two types of reliability will be examined, including intra-rater reliability and interrater reliability and four types of validity will be assessed, including concurrent validity, convergent validity, discriminant validity, and external validity.
XKH001is a recombinant humanized monoclonal IgG1 antibody for subcutaneous injection. XKH001 specifically blocks interleukin-25 from binding to its receptors. To evaluate the safety, tolerability, pharmacokinetics (PK) of single ascending doses of XKH001 injection following subcutaneous administration
The purpose of this study is to characterize the effect of PF-06882961, administered at 2 steady-state dose levels, on the PK of single doses of atorvastatin (20 mg) or midazolam (5 mg), administered separately, in healthy adult male and female participants (Part A), or an OC in healthy PM female participants (Part B).
The overall objective of the study is to determine whether self-rated, perceived immune fitness (using questionnaire) is associated with biological assessment of immune fitness (immune signatures in the blood).
This is a safety, tolerability, and pharmacokinetic study in 2 cohorts of healthy male participants with an option for an additional cohort. Cohorts 1 and 2 will receive once daily by mouth CORT113176 150 mg and 300 mg, respectively, for 14 days under fed conditions. Progression from Cohort 1 to Cohort 2 will be done based on the safety and tolerability outcome in Cohort 1 and after Cohort 1 has received the study drug for at least 7 days. The optional Cohort 3 may receive a higher dose that will not exceed CORT113176 450 mg once daily by mouth for 14 days under fed conditions. The progression from Cohort 2 to the optional cohort (Cohort 3) will be based on the same precautions as with the progression from Cohort 1 to Cohort 2. Each participant will undergo safety evaluations. Pharmacokinetics of CORT113176 will be assessed in plasma and cerebrospinal fluid (CSF) samples. Pharmacodynamic assessments will include the measurement of serum cortisol.
A randomized, double-blind, parallel-group study in Chinese healthy male subjects to evaluate the pharmacokinetics, pharmacodynamics, safety and immunogenicity of LY06006 versus Prolia following single-dose subcutaneous injection
A Phase 1 Study of the Effect of Acid-reducing Agents on the Pharmacokinetics of a Single Oral Dose of Sitravatinib in Healthy Adult Subjects. The study is a single-center, open-label, 2-period, 2-treatment, fixed-sequence crossover, parallel-group study.
In this research study, the investigators will use a novel approach to measure what people eat. The goal is to find out whether stable isotopes that can be measured in blood, hair, and fingernails are better at measuring what people eat than the surveys that are currently used. To meet the goal, the investigators will do three things. First, the investigators will feed study participants known amounts of foods and nutrients. Second, after study participants have eaten the food, the investigators will measure stable isotopes in samples of study participants' blood, hair, and fingernails. Third, the investigators will determine how well these samples reflect what was eaten. The investigators will also give surveys to study participants to determine how well the surveys reflect what was eaten. This will allow the investigators to do a relative comparison of the measurements from isotopes and surveys.
It has been reported that in the first stages of the pandemic, a significant portion of the general population experienced psychological problems such as anxiety, depression and post-traumatic disorders. These problems persist today. A balanced diet, physical activity participation and relaxation techniques are recommended for preventing such problems. In studies conducted before the pandemic, it is reported that breathing exercises have positive effects on anxiety, sleep and quality of life in both patients and healthy individuals. Aim of this study is to investigate the effects of breathing exercises applied via teleconference on fear of COVID-19, anxiety, sleep and quality of life in healthy adult population.
The purpose of the study is to provide safety, tolerability, pharmacokinetics and food effects data of a single 8 mg oral dose of EC5026 in healthy subjects.
