CMT is a rare disease for which novel treatments are being developed. Evaluation of intervention efficacy is hampered by slow progression and lack of sensitive outcome measures. Primary goal of the project is to identify and validate RNA and protein derived biomarkers in blood of CMT patients for selected outcome measures over 2 years. The investigators expect to develop more responsive outcome measures and circulating biomarkers to improve assessment of intervention efficacy in forthcoming therapeutic trials.
Vitamin D deficiency is common among otherwise healthy pregnant women and may have consequences for them as well as the early development and long-term health of their children. However, the importance of maternal vitamin D status has not been widely studied. The present study is divided into a societal experiment (1) and a case-cohort study (2): 1. The present study includes an in-depth examination of the influence of exposure to vitamin D early in life and during critical periods of growth for development of type 1 diabetes (T1D), type 2 diabetes, gestational diabetes, pre-eclampsia, obesity, asthma, arthritis, cancer, mental and cognitive disorders, congenital disorders, dental caries and bone fractures during child- and adulthood. The study is based on the fact that mandatory fortification of margarine with vitamin D, which initiated in 1937, was terminated in 1985. Apart from determining the influences of exposure prior to conception and during pre- and postnatal life, the investigators examined the importance of vitamin D exposure during specific seasons and trimesters, by comparing disease incidence among individuals born before and after the fortification. 2. Additionally, a validated method was used to determine neonatal vitamin D status using stored dried blood spots (DBS) from individuals who develop the aforementioned disease entities as adults and their time and gender-matched controls. Unparalleled, the study will help determine the effects of vitamin D exposure during critical periods in life. There are a sufficient number of individuals to verify any effects during different gestation phases and seasons of the year. The results, which will change our current understanding of the significance of vitamin D, will enable new research in related fields, including interventional research designed to assess supplementation needs for different subgroups of pregnant women. Also, other health outcomes can subsequently be studied to generate multiple new interdisciplinary health research opportunities involving vitamin D.
Introduction and Research Problem: The aim of this project is to evaluate and compare two full coronal restorations on primary posterior molars over a period of 3, 6 and 12 months in terms of restoration failure, marginal integrity, proximal contact, secondary caries, occlusion and gingival response. The restorations types are Stainless Steel Crowns (SSC) and NuSmile Zirconia Crowns (Nu/ZR). Materials and Methods: Children attending the King Abdulaziz University, Faculty of Dentistry (KAUFD) clinics who need restorations will be screened for inclusion criteria till 120 teeth are recruited (60 teeth for SSC restorations and 60 for Nu/ZR restorations). Split mouth technique will be used to ensure equalizing variables for both groups, each patient will have side restored with SSC and the opposite side will be restored with Nu/ZR crowns. Randomization will be done using Statistical Package for the Social Sciences (SPSS) software version 20.0 (Armonk, New York; International Business Machines Corporation (IBM Corp) for each age group separately with a uniform random variable generation. A simple descriptive statistics will be used for analysis and a T-Tests with Wilcoxon Signed-Rank will be used. Level of significance will be set at (α = 0.05) and level of confidence at (95%).
Charcot Marie Tooth (CMT) is the most common inherited neuropathy. It affects the nerves of the hands and feet first, slowly progressing towards the centre of the body. It causes varying degrees of weakness and reduced feeling, usually affecting the feet and ankles first. High incidence of falls and knock on effects in quality of life are common. This is a lifelong condition which, though not life limiting, does not have a cure. Research into the effect of balance rehabilitation in people with CMT has been limited to traditional exercises, which do not address the complex nature of balance impairments in this condition. Multi-sensory rehabilitation has proved beneficial in improving balance in people with sensory neuropathy. Research shows that strengthening trunk muscles can improve balance in older people. Trunk and muscles close to it are largely unaffected in people with CMT, therefore these muscles could be strengthened in these patients. This study proposes to assess the feasibility of multi-sensory balance training, strength training with a focus on the trunk and muscles close to the trunk, and falls management education. This comprehensive approach is reflective of a clinical physiotherapy programme. Though a life-long condition, many people with CMT lead full lives. A home based programme is proposed to so that patients can fit it into their lives without having to travel for treatment. Therapists will use self-management principles within treatment. Measurements will be taken prior to and following treatment including physical measures, questionnaires and interviews. The physiotherapy interventions will be taught home and data collection will be at the National Hospital for Neurology and Neurosurgery, University College London Hospitals (UCLH).
The single-center, open-label Phase II study has the objective of assess the effect of MD1003 on motor and sensory conduction in patients suffering from demyelinating polyneuropathies in 15 subjects.
The objectives of this study were to compare the precision of two digital intraoral scanners from a series of repeat scan images, and to investigate the effect of the learning curve on changes in trueness when scanning the full arch of the oral cavity in actual patients.
This study evaluates the clinical effect of regenerative endodontic procedure using PRF in immature permanent teeth with apical periodontitis. Half of participants will receive the PRF instead of blood clots in the regenerative endodontic procedure, while the other half will receive a blood clots in the regenerative endodontic procedure.
The purpose of this study is to learn about focal compressive median neuropathy at the wrist (Carpal Tunnel Syndrome) and outcomes of therapies (e.g. conservative and surgery) in the upper extremities of patients diagnosed with an inherited neuropathy. All patients enrolled in the Rare Diseases Clinical Research Network (RDCRN) Inherited Neuropathies Consortium (INC) Contact Registry who have marked one of the following disorders: CMT1A, CMT1B, CMT2A, CMT4, CMTX, other known CMT peripheral neuropathy, other unknown CMT peripheral neuropathy, or Hereditary Neuropathy with liability to Pressure Palsies (HNPP), will be invited via email to participate in this online study.
The purpose of this study is to determine whether PXT3003 is effective and safe in the treatment of Charcot-Marie-Tooth disease - Type 1 A (CMT1A). This double-blind study will assess in parallel groups 2 doses of PXT3003 compared to Placebo in CMT1A patients treated for 15 months.
