Filter by:Runners often experience acute/chronic pain due to pre-existing structural somatic dysfunction and/or acquired various overuse injuries of the lower extremity, specifically affecting the ligaments, tendons, muscles and bones. Common structural and function dysfunctions include but are not limited to patellofemoral pain syndrome (PFPS), Achilles tendonitis, iliotibial band syndrome (ITBS), ligamentous and muscle tears, muscle sprains/strains, stress fractures, pes planus, plantar fasciitis, and shin splints. The purpose of this study is to assess the correlation between acute and chronic pain, overuse injuries, and observational and palpatory findings upon evaluation. With an understanding of the common trends of somatic dysfunctions and etiology of the pain/injury, modified regimen/routine and improved treatment plans can be developed and recommended for runners to better rehabilitate, minimize relapse and reduce compensatory injuries. No medical or osteopathic treatment will be provided.
To prospectively investigate the efficacy of an insertable cardiac monitor-guided atrial fibrillation (AF) management in reducing subsequent AF burden in patients with persistent or paroxysmal AF undergoing atrial catheter ablation (CA).
Multiple sclerosis (MS) is a chronic, inflammatory disease of the central nervous system. Lack of physical activity is common in people with MS (pwMS). This can lead to several comorbid conditions such as obesity, metabolic syndrome, osteoporosis, hypertension, diabetes and worse prognosis. An increasing number of studies suggest that physical exercise can play an important role in managing symptoms, preventing complications and comorbidities in pwMS, and may possibly be neuroprotective. However, doing exercise can be very challenging for pwMS who have moderate/severe mobility disability and who have problems with walking. In this project, the investigators will explore the use of a powered Exoskeleton as an exercise tool for people with moderate to severe difficulty walking due to MS. Powered Exoskeletons are wearable robots that offer opportunity to persons with lower limb weakness to stand and walk. The Exoskeleton-assisted training provides active training with potentially much less intervention needed from therapists. However, it is not clear whether pwMS can walk with a powered Exoskeleton at speeds and intensities sufficient to positively affect health and fitness outcomes. Thus, in this study, the investigators aim to explore whether using an Exoskeleton will enable people with MS to exercise at a moderate intensity and whether people with MS find this acceptable and safe to do on a regular basis. The investigators will also explore whether training with an Exoskeleton can improve walking. The investigators will train 12 patients with MS to walk with an Exoskeleton twice a week for 8 weeks. The investigators will compare the effects with another group of 12 patients who will do exercises with a fitness instructor twice a week for 8 weeks. The investigators will study whether walking with Exoskeleton is better than fitness training in terms of fitness outcomes, walking and cognitive, psychological factors.
PENGUIN is a pragmatic multi-center trial investigating the effects of pre-operative mouthwash and perioperative oxygen on the incidences of pneumonia and surgical site infection (SSI) following major abdominal surgery. Patients will be recruited from low and middle income countries and randomly assigned to a trial treatment arms: a) pre-operative chlorhexidine mouthwash and 80-100% FiO2; b) no pre-operative mouthwash and 80-100% fraction of inspired oxygen (FiO2); c) pre-operative chlorhexidine mouthwash and 21- 30% FiO2; or d) no pre-operative mouthwash and 21-30% FiO2.
Rationale: Hepatic encephalopathy (HE) is a major and common complication in patients with liver cirrhosis. HE can be classified in the extensive range of neurocognitive deterioration as minimal HE (MHE), covert HE (grade I), or overt HE (OHE, grade II-IV). Liver cirrhosis is the most common cause of portal hypertension (PH). Patients who develop complications of PH, like variceal bleeding or refractory ascites, can benefit from a Transjugular Intrahepatic Portosystemic Shunt (TIPS) placement. Unfortunately, post-TIPS HE is a common and often severe complication. Incidence of new onset or worsening of HE after TIPS is approximately 20-45%. Currently there is no strategy to prevent post-TIPS HE.
The aim of this study is the efficacy of a docosahexaenoic acid (DHA)-rich dietary supplement in improving key dementia-related mechanisms and cognitive function in older people at risk for dementia. This is a randomized placebo-controlled, 24 weeks, phase 2 study of Omega 3 in people with increased risk of dementia. The aim is to explore the effects of DHA on cognitive performance (CERAD 10 word memory tests, TMT A/B, Stroop Color-Word, FAS, VOSP silhouettes, Cantab-test (RT, PAL, SWT)), biological markers (blood: CRP, NLF, TNF-alpha, MCI-1, PBMC Abeta middomain, Omega-3-index, IL, CSF: NLF, sTREM2, Ab 1-42, total and -phospho-tau) and imaging (MRI: standard structural DDI protocol including Freesurfer and WML measurements, DTI and ASL).
The primary objective is to patient-reported Quality of Life related to complete control of Radiation Induced Nausea and Vomiting (RINV) between standard palliative radiotherapy and VMAT. Secondarily, we will assess rate of complete control of RINV. However, the investigators hypothesize that there will be no difference in pain response between the two arms, because they are receiving the same dose.
Dexmedetomidine（DEX）is a potent and highly selective α 2 adrenergic receptor agonist. It has the pharmacological effects of sedation, hypnosis, analgesia, anti-sympathetic and neuroprotective. Its sedative effect is similar to normal sleep, and easy to wake up. DEX is widely used clinically because of its advantages and acceptable side effects. The best clinical use of DEX is uncertain, including intravenous, intramuscular, oral, intralnasal and sublingual administration. Its clinical recommended use is intravenous load infusion for more than 10 minutes, followed by continuous infusion. However, the clinical recommended usage is inconvenient, time-consuming and other shortcomings, for the growing popularity of daytime surgery, will inevitably affect the operation process and turnover. If a suitable dose range of DEX can be found for a single intravenous injection to achieve clinical efficacy quickly without significant hemodynamic effects, this will improve the patient's postoperative recovery. We will speed up the utilization and turnover of medical resources. The aim of this study was to investigate the optimal dosage of DEX for single intravenous injection.
Evaluation of endothelial glycocalyx damage in on-pump conventional coronary artery bypass surgery using a syndecan-1 (CD138) blood test. The study will be carried out in two stages. Pilot study for testing and correcting research methodology and the main study.
The study consist of a retrospective analysis of the etiologies, investigations and outcomes of patients presenting between 2005 to 2010 with hemoptysis in a North-American Tertiary center.
