Filter by: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.
The objective of the study is to confirm the clinical relevance of the novel biomarker for traumatic brain injury (TBI) detection. Samples of blood, urine and saliva will be collected from a) patients with suspected TBI (isolated), b) patients with orthopedic injury, and c) healthy controls. The sponsor will do biochemical investigations for the samples to evaluate the presence, level and structure of the targeted biomarker.
Early intervention attempts to shorten protracted delayed union (DU) or prevent non-union (NU) fractures are hampered by lack of validated quantitative assessment tools for bone fracture healing during normal and delayed healing processes. In actual practice, sequential X-rays usually follow a pre-determined time interval in patients with fractures.They constitute the best available state of the art used by surgeons to assess the fracture healing course. In an attempt to improve between raters reliability of radiographic assessment of healing, studies have explored a novel radiographic assessment for tibial shaft fractures, the Radiographic Union Scale for Tibial Fractures (RUST). The RUST assesses the presence of bridging callus and a fracture line on each of four cortices (seen on anterior-posterior and lateral views). This callus based scoring system has been since extended to other bones than the tibia in a retrospective case series. It has been renamed modified radiological union score (mRUS) and has shown potential value in bone healing measurement. Based on an initial retrospective study in nail-treated fractures, the first objective of the present investigation is to prospectively validate mRUS as a tool to identify patients at increased risk of DU and NU within the first 75-110 days after fracture occurrence. This prospective validation will be performed on a retrospective cohort of patients having sustained long bone fractures, including both upper and lower extremities. A further objective of the present investigation is to apply the scoring system to tomographic imaging in case of nail/plate treated fractures, deriving a tomographic union score (TUS) and first assess its potential value in bone healing for fractures treated by nails/plates.
The PAINFREE (Improving PAIN control following FRactures; towards an Elder-friendly Emergency department) Initiative is a patient-centered multifaceted intervention which aims to improve pain management in patients 75 years and older presenting with a fracture at 7 Emergency Department of participating Montreal hospitals: 1. Montreal General Hospital 2. Royal Victoria Hospital 3. Ste Mary's Hospital 4. Hôpital de Verdun 5. Hôpital du Sacré-Coeur de Montréal 6. Jewish General Hospital 7. Lakeshore General Hospital
The purpose of this study is to evaluate the safety and efficacy of the gene-activated bone substitute consisting of octacalcium phosphate and plasmid DNA encoding vascular endothelial growth factor (VEGF) for maxillofacial bone regeneration. The patients with congenital and acquired maxillofacial bone defects and alveolar ridge atrophy will be enrolled.
To verify whether digital three-dimensional model-assisted internal fixation can obtain better effects in the repair of complex long bone fractures compared with conventional internal fixation.
This study is designed as a single-blind RCT in 80 postmenopausal women to compare the effect of immediate administration of daily calcium supplementation (1000 mg calcium) or two daily dosages of calcium + vitamin D (1000 mg calcium + 880 IU vitamin D or 1000 mg calcium + 1760 IU vitamin D) to standard care (administration of vitamin D3 12 weeks after fracture) in terms of calculated bone strength based on analysis of cortical and trabecular bone parameters using HR-pQCT, fracture healing and functional outcome.
Objective: The investigators initiated a pilot clinical study to test safety and preliminary efficacy in humans (bone tissue repairing capacity) and to evaluate standard clinical and rehabilitation protocols. Summary Background Data: Bone tissue engineering scaffolds loading growth factors have been considered as the most perspective among all bone substitutes, yet little progress of its clinical translation has been made. The concept of "micro-scaffolds" was proposed in this study to provide a trajectory to its clinical translation. Methods: Pre-cured CPC/rhBMP-2 micro-scaffolds have been successfully developed and further applied as an easy-to-operate filler for bone regeneration in a pilot clinical study. Patients of tibial plateau fractures, proximal humeral fractures, or calcaneal fractures at a similar level of severity were randomly divided into two groups and treated by CPC/rhBMP-2 microffolds or traditional CPC paste (control group).
This single center, randomized control, double blind trial will prospectively examine the feasibility of intranasal, sub-dissociative (IN) ketamine versus intranasal fentanyl for pain control in the pediatric emergency department setting. The investigators hypothesize that IN ketamine may provide a safe and effective alternative to IN fentanyl for children with suspected, isolated extremity fractures. Eighty children ages 3-17 years with a suspected, isolated extremity fracture that requires analgesia will be randomized to receive IN ketamine or IN fentanyl upon presentation to the emergency department and will be followed for 2 hours for efficacy and 6 hours for safety.
The purpose of this study is to validate the long-term benefit of denosumab for osteoporosis treatment in a real-world clinical practice setting. We hypothesize that continued therapy (36+months) with denosumab will increase both trabecular bone score (TBS) and femur strength index (FSI) and reduce fracture and other bone health risks among post-menopausal women with osteoporosis.
