NCT ID: NCT03403959 Completed - Visual Impairment Clinical Trials

Seasonal Affective Disorder and Visual Impairment

Start date: December 1, 2017
Phase: N/A
Study type: Interventional

As a subtype of major depressive disorder, seasonal affective disorder (SAD) or winter depression causes severe reductions in both quality of life and productivity and results in high morbidity and frequent sick leave (1). SAD is a prevalent disorder with rates as high as 3-5% in central European countries and 8-10% in Scandinavian countries. In our recent screening survey among persons with severe visual impairment or blindness (visual acuity < 6/60), we found a strikingly high prevalence of SAD of 17 % compared to 8% in the fully sighted control group. Persons with maintained light perception had a highly increased SAD prevalence of 18 % whereas no light perception (NLP) respondents had an SAD prevalence of 13 %. Light is unquestionably of great importance in the development and treatment of SAD. It is suggested that a reduced retinal sensitivity to light leads to sub-threshold light input to the brain and consequently to the development of SAD. The novel retinal non-visual photoreceptors, the intrinsically photosensitive retinal ganglion cells (ipRGCs), are involved in the regulation of circadian rhythm and mood and their function are in part independent of the function of the classical rod and cone photoreceptors which form the basis of conscious visual perception. Function of the ipRGCs can be assessed by chromatic pupillometry where the sustained pupillary contractions following blue light stimulation (PIPR) is the main outcome. In persons with SAD without eye disorder the function of the ipRGCs is reduced. We here wish to investigate associations between ipRGC function and SAD symptoms, circadian profile and treatment response to light therapy in persons with visual impairment. Persons with visual impairment (SAD and non-SAD) are assessed for ipRGC function with chromatic pupillometry, for seasonal mood variation by interview and questionnaire and for diurnal melatonin secretion by saliva analysis summer and winter. In winter SAD participants are treated with daily morning bright light for 6 weeks. Reduction in depression scores and tolerability is recorded.

NCT ID: NCT03403517 Completed - Clinical trials for Complication, Postoperative

Preoperative High Dose Steroids for Liver Resection- Effect on Complications in the Immediate Postoperative Period

STEREO
Start date: December 11, 2017
Phase: Phase 4
Study type: Interventional

Background: Several randomized clinical trials have shown beneficial effects of pre-operative glucocorticoids on post-operative complications. Studies on the effects of glucocorticoids on the postoperative recovery after liver-resection show significantly lower markers of infection and liver damage, and some studies have shown a shorter hospital stay. Studies on the effects in the immediate postoperative phase are lacking. Methods: Randomized, double-blind, controlled trial evaluating incidence of postoperative complications in the immediate postoperative phase (and during admission) after open liver surgery. Participants are randomized to either active treatment (methylprednisolone 10 mg/kg) or control (8 mg dexamethasone), administered just prior to surgery. All patients undergoing open liver resection at our institution are eligible. Included patients are stratified according to extent of surgery into minor (<3 segments) or major (≥3 segments) group. Patients in major group participate in Substudy I (markers of endothelial damage). Patients operated between January and July 2018 participate in Substudy II (delirium).

Start date: December 1, 2017
Phase: N/A
Study type: Interventional

A cross validation study comparing an international acknowledged assessment tool "Endoscopy Training System" (ETS) and movement analysis of the colonoscope based on raw data from coils within the scope. 24 physicians are recruited and divided based on experience (novices and experienced). All participants are to perform twice on the ETS that is based on four tasks; Scope manipulation, tool targeting, loop management and mucosal inspection. The movement of the colonoscope will be gathered during the tasks and correlated to the scores of the ETS.

NCT ID: NCT03401307 Completed - Multiple Sclerosis Clinical Trials

Central and Peripheral Nervous System Changes as Markers of Disease Progression in Multiple Sclerosis

Start date: August 1, 2017
Phase:
Study type: Observational

OBJECTIVE To investigate neurodegeneration and demyelination in the central and peripheral nervous system in multiple sclerosis linked to disease progression and mechanisms that can explain different responses to Fampridine treatment in MS patients with walking disability. METHOD The study is a prospective cohort follow-up study with 98 participants with MS and walking disability. Participants are identified as responders or non-responders to Fampridine treatment prior to the study. Participants will undergo MRI of the cerebrum with lesion load quantification, neurophysiological tests comprised of motor evoked potentials and electroneurographic examination, blood samples examining KIR4.1 antibodies, brain derived neurotrophic factor (BDNF), myelin protein zero (MPZ), peripheral myelin protein 22 (PMP22), p75-nerve growth factor receptor (p75NGFR) and anti-myelin associated glycoprotein (anti-MAG). The presence of SORCS-3 gene mutation will also be examined, as will cerebrospinal fluid levels of myelin basic protein, neurofilament heavy and light chains. Functional test of Timed 25-foot walk test (T25FW) will identify response to Fampridine treatment. A functional test battery will further detail function of upper extremities and cognition. CONCLUSION This study will add to the understanding of neurodegeneration and demyelination in CNS and PNS in patients with MS having walking disability. This will impact clinical decision-making by improving organization of immunomodulatory treatment, identifying biomarkers thus facilitating earlier treatment and improving patient control, information and education.

NCT ID: NCT03401138 Completed - Fracture of Hip Clinical Trials

Hemodynamic Monitoring and Resuscitation in Hip Fractures

Start date: February 14, 2018
Phase:
Study type: Observational

Background: Fracture of the hip is a potentially fatal event in an elderly, frail, highly comorbid patient group suffering from dehydration and hypovolemia, and it carries a risk that equals major trauma in young patients in regard of physiological insult and severity, yet no preoperative resuscitation and transfusion strategy is available. An important goal of hemodynamic monitoring and resuscitation is early detection of insufficient tissue perfusion and oxygenation. The peripheral perfusion index reflects changes in peripheral perfusion and blood volume and a decreased peripheral perfusion index predicts surgical complications and morbidity in acute surgical and septic shock patients. The research group hypothesize that elderly frail patients with a fracture of the hip suffer from hypovolemia and peripheral hypoperfusion of varying degrees and accordingly respond to controlled fluid resuscitation and that the non-invasive peripheral perfusion index will serve as an early predictor of a deteriorated circulation in reflection of stroke volume. Methods: The main objective of this prospective observational study is to assess to what extend patients with fracture of the hip suffer from hypovolemia and respond to a fluid challenge. The secondary objectives are to evaluate correlation between the minimally-invasive measurements of stroke volume and blood volume and the non-invasive measurement of peripheral perfusion index and near-infrared spectroscopy, as well as prevalence of postoperative complications and mortality. Fifty consecutive patients over the age of 65 years, presenting with a hip fracture, treated in a multimodal fast-track regimen, will be included when written informed consent is available. All patients will receive epidural analgesia and preoperative stroke volume-guided hemodynamic optimization. Blood volume measurements are performed and all patients are monitored with peripheral perfusion index and near-infrared spectroscopy. Discussion: This is likely the first study to address clinically applicable hemodynamic monitoring and resuscitation in patients with fracture of the hip where adequate resuscitation is easily missed. The study group aim to evaluate the feasibility of preoperative stroke volume-guided hemodynamic optimization in the context of minimally- and non-invasive monitoring of peripheral perfusion and blood volume measurements.
