Filter by:Spinal cord injury (SCI) is a devastating disability with physical, social and vocational consequences. Owing to its overwhelming complications, the cost of treatment and rehabilitation increases constantly. Persons with spinal cord injury are always dependent on their families in most of house hold, recreational and activities of daily life. Majority of SCI are incomplete classification C or D as per American spinal injury Association (ASIA). Due to certain spared pathways intrinsic mechanism of neuroplasticity take place in incomplete spinal cord injuries (iSCI) which is liable for natural recovery, but this potential is limited and often slow. Therefore there is need for some advance therapeutic interventions which may enhance neuroplasticity and improve functional recovery in individuals with iSCI. It has been reported that acute intermittent hypoxia (AIH) increase neuro plasticity by causing release of spinal serotonin which stimulate serotonin type 2 (5-HT2) receptors that undergoes a series of mechanisms which increase brain derived neurotrophic factors (BDNF) which subsequently enhance motor functions of upper and lower limbs in iSCI. Despite of the growing body of literatures supporting that AIH improves both upper limb and lower limb functions along with walking ability and speed. However, their results are limited to small sample size, gender biased and lack of intralimbs assessment. As per the author knowledge, these literatures lack retention effects of AIH on upper and lower limb function. In addition variables like quality of life, disability and some biomarkers related to hypoxic effects have not been reported in any of these studies. Furthermore, it is hypothesized that variant geographic locations and socioeconomic status may affects persons with iSCI differently. So in light of these literature gaps, the author aim is to investigate the effects of AIH in upper and lower limb motor function, balance, quality of life and disability. In addition, the effects of AIH on brain derived neurotrophic factors (BDNF), hemoglobin (Hb) level, numbers of RBS and hematocrits will be assessed.
To study the safety and efficacy of intranasal administration of exosomes derived from mesenchymal stromal cells on long-term neurodevelopmental outcome in extremely low birth weight infants born at gestational age 25/0-27/6 weeks.
This prospective observational study will enroll 60 moderate-to-severe OSA patients (AHIā§15/hour, 30 obese [BMI>=27] & 30 non-obese [BMI<27]) and 40 age-, gender-, BMI-matched controls without OSA. Venous blood 10 ml will be collected to isolate neutrophils, which are later tested for their ability to produce neutrophil extracellular traps (NETs) under the effect of PMA (phorbol 12-myristate 13-acetate). The test will be repeated if OSA patients receive CPAP therapy (continous positive airway pressure therapy).
Sleep disordered breathing is associated with impaired glucose tolerance and incident diabetes. Nocturnal hypoxemia is a potential stimulus of glucose intolerance. It is especially severe and highly prevalent in high altitude residents. Intervening on nocturnal hypoxemia may therefore improve glucose control and decrease the public health burden in high altitude populations. The objective of this study is to examine the impact of hypoxemia on glucose homeostasis in high altitude residents. The investigators will address this objective by examining the effect of supplemental oxygen on glucose in a randomized cross-over study.
Investigation of the Clinical Efficacy of High Flow Nasal Oxygen in Patients Over 60 Years of Age Undergoing Colonoscopy
The purpose of this study is to determine if taking iron supplement pills improves exercise performance in low-oxygen conditions.
Estimating and recording the rate of occurrence of pulmonary and cardiovascular complications during the perioperative period in patients with past covid infection
The aim of this study is to evaluate the impact of the FreeO2 system on the quality of the oxygen therapy in confirmed or suspected SARS-CoV-2 patients in the emergency department.
The aim of this study is to characterize the protective pattern of intermittent hypoxia, angina pectoris and remote ischemic conditioning, in reperfusion injury by determining and monitoring the plasma immunometabolic parameters of patients with STEMI. This could contribute to better understanding of this phenotypic pattern with translation into clinical practice.
The aim of the study is to compare two methods of oxygen therapy in patients with acute respiratory distress syndrome in the course of SARS-CoV2 pneumonia. The initial method of oxygen supply during coronavirus pneumonia is conventional oxygen therapy using a face mask or nasal cannula. However, there have been reports in the literature that early initiation of high-flow oxygen therapy with a nasal cannula is associated with better prognosis. The study we perform is intended to provide reliable evidence for confirmation this hypothesis.
