NCT03728595
Patients with chronic lung diseases travelling by plane often suffer with symptoms related to lower oxygen levels they are exposed to while flying. Therefore, patients with respiratory conditions are routinely assessed to establish if they need supplemental oxygen in flight. A hypoxic altitude simulation test (HAST) is often part of this assessment and consists in having patients breathe a oxygen/nitrogen blend with a lower oxygen concentration compared to normal room air, simulating in-flight conditions. Oxygen levels are measured before and after the test through a blood sample (from the earlobe or an artery in the wrist) and with a finger probe. In-flight oxygen is required if the oxygen level in the blood is lower than 6.6 kPa. HASTs are time consuming, costly, and require a dedicated hospital appointment. Using historical data, the Investigators developed scores based on capillary blood gas (blood sample from the earlobe), diagnosis and sex to predict the outcome of the HASTs. The Investigators validated the proposed scores in a separate historic cohort of patients and showed it had good concordance with the HASTs results. In this study, the Investigators want to confirm prospectively if the score, based on blood results (venous and/or earlobe), can predict the outcome of the HASTs and therefore reduce the number of tests performed, travel time for patients, and costs for the NHS. All patients, aged 18 or older, who are having a HAST for clinical purposes at the cardio-respiratory lab at Leeds Teaching Hospital NHS Trust will be invited to take part in the study. The Investigators will record diagnosis, results of HAST and previous spirometry from the medical notes, perform a spirometry if not done in the previous 12 months and collect a blood sample (one tube, 4 mls). With these data, the Investigators will calculate the score and assess its agreement with the outcome of the HAST. Each participant's involvement in the study will last for approximately 90-120 minutes, which is the normal duration of a HAST. The Investigators aim to include up to 280 subjects in the study.

Our protocol, named "KETOMIGRAINE", is based on the prescription of a Ketogenic Diet (KD) to twenty subjects with diagnosis of Chronic Migraine (CM), resistant to oral preventive treatments and non-responders to monoclonal antibodies targeting the CGRP pathway. The trial starts with one month of baseline during which are verified inclusion/exclusion criteria. After that, participants will assume KD for three months, a transitional diet (TD) for other three months. Follows a period of three months of free diet (FD). Neurological and dietician visits are scheduled during the course of the trial.

NCT05314452
Timed Motor Function Tests (TMFTs) determined the walking abilities of an individual. During Covid-19 pandemic direct observation may not be feasible to record Timed motor function in children. Hence, the reliability and validity of video based observation and online based observation (VBO and OBO) methods to be explored. Middle school going children age group between 8 and 12 years was recruited for the study on the basis of convenience sampling. Sample size selected for each age group was according to sample size criteria of Interclass coefficient analysis. After anthropometrics, 10 meters walk test was recorded using three methods; VBO, OBO and direct observation for three times to estimate intrarater reliability and three days within a week to estimate test-retest reliability. The mean of three readings was used to find the estimated value. Direct observation method was used as a criterion measure method to report concurrent validity. After concurrent validity, Test-retest Reliability and Intrarater Reliability of VBO and OBO was reported. Reliability and validity of VBO and OBO with direct observation was reported by recording 10 meters walk test in children.

Transcranial magnetic stimulation (TMS) is a procedure that has been shown to improve fatigue in chronic sufferers. It uses a plastic covered coil that sends a magnetic pulse through the skull into the brain and by targeting particular areas in the brain it can be used to help modulate the perception of fatigue. The study intends to use this technique to treat such a disabling symptom in patients who suffer from Multiple System Atrophy (MSA). Initially the aim is to study this technique in 22 MSA patients who are suffering from fatigue . These patients would require an resting-state funtional MRI before and after the stimulation. The stimulation would be performed ten sessions and the patients would be assessed by a clinician using well recognized clinical tools. It is anticipated that there will be a meaningful improvement in fatigue. It is also anticipated that TMS is a safety technique to use in MSA patients . Our findings will revealed that fatigue may be associated with an altered default mode network and sensorimotor network connectivity in MSA patients. We hypothesize that these divergent motor and cognitive networks connectivity changes and their adaptive or maladaptive functional outcome may play a prominent role in the pathophysiology of fatigue in MSA.

NCT05314049
Lumbar degenerative disc disease and discogenic low back pain is comparatively common and disabling musculoskeletal condition. McKenzie's extension protocol is considered to be the gold standard physical therapy treatment for persons with acute discogenic low back pain, however the evidence is deficient in terms of additive benefits of sustained natural apophyseal glides in the management of discogenic low back pain. Thus, the current study will not only look into the positive effects of McKenzie's extension protocol in the management discogenic low back pain, but will also look into the additive benefits of sustained natural apophyseal glides in combination with McKenzie's extension protocol in the management of discogenic low back pain.

NCT04918576
Hematoma is a common complication of bilateral breast reduction (BBR) surgery. This can lead to pain and discomfort experienced by the patient, in addition to greater use of valuable healthcare resources. Previous studies have shown correlation between the use of tranexamic acid (TXA), an anti-fibrinolytic, and reduced post-surgical bleeding complication events. In this randomized control trial (RCT) evaluation TXA use in BBR, for which one breast will be randomized to have TXA applied topically, while the other will have normal saline (NS) placebo applied. The primary objective of this prospective blinded randomized control trial study is to determine if the administration of topical TXA in BBR reduces the incidence of surgical site hematoma compared to placebo within 2 weeks following surgery. The results of this study will be used to inform the design of a larger multicentered RCT on TXA in breast surgery.
