Role of Mirtazapine in Ameliorating Sleep Disordered Breathing
Spinal Cord InjuriesSleep Disordered BreathingThe purpose of this study is to look at the effect of using Mirtazapine to target a specific pathway in the body, that relies on a natural chemical the body produces called 'serotonin', in patients with spinal cord injury (SCI) and non-injured persons during sleep. During this part of the study participants will be asked to take Mirtazapine (15mg per day) and a placebo in a random fashion, each for a one week period (drug period) of time followed by one week without drugs (washout period). The drugs will not be taken all at the same time, but each will be taken separately for one weeks followed by a night study to look at the effect the Mirtazapine/placebo pill has on the way the body responds during sleep.
Effects of Inspiratory Muscle Training on Dyspnea in Subjects With Chronic Obstructive Pulmonary...
Chronic Obstructive Pulmonary DiseaseThe purpose of this study is to determinate whether inspiratory muscle training (IMT) associated with a conventional respiratory rehabilitation program is more effective than a conventional respiratory rehabilitation program alone,on Dyspnea in chronic obstructive pulmonary disease (COPD) subjects with a normal maximum inspiratory pressure (IP > 60 cmH2O).
LipoAerosol© Inhalation After Tracheostomy
Other Tracheostomy ComplicationPatients after tracheostomy represent a substantial part in the ear nose throat clinic. Long-term intubated patients in intensive care units also profit from tracheostomy due to an improved respiratory toilet. However, after tracheostomy patients demonstrate shunt ventilation bypassing the sinonasal and pharyngeal system. The physiological moistening, cleaning and warming of the breathing air fail resulting in a respiratory inflammation. Beside a variety of supportive medical devices no general recommendation exists at present. Recently, we demonstrated the beneficial application of local phospholipids in Sjoegren's syndrome and antineutrophil cytoplasmatic antibody associated sinonasal vasculitis. In the current monocentric, two-armed, double-blinded, randomized parallel group study we would like to evaluate the beneficial application of LipoAerosol© when compared with standard physiologic saline inhalation. LipoAerosol© is a licensed, tradable medical device and will be applied as part of its intended use. Liposomal inhalation solution provides moistening, cleaning and warming of the upper and lower respiratory tract and supports the natural moistening film in airway irritations and diseases. Blood parameter (leucocytes and c reactive protein) and tracheobronchial secretion (Lymphocyte subpopulation, c reactive protein, lactate dehydrogenase, granulocyte macrophage colony stimulating factor, interferon γ, interleukins 10, 12 (p70), 13, 1β, 2, 4, 5, 6, 7, 8, tumor necrosis factor α) will be collected 1, 3, and 10 days after tracheostomy. In addition, medical examination records the number of suction maneuver (0 points: none; 1 point: 5-10x/d; 2 points: 10-20x/d; 3 points: >20x/d), flexible-optical assessment of tracheo-bronchial redness (0 point: none; 1 point: peristomal; 2 points: tracheal; 3 points: tracheo-bronchial) and flexible-optical assessment of mucous congestion (0 point: none; 1 point: fluent; 2 points: tenacious; 3 points: barky). Subjective estimation of the respiratory impairment will be analyzed via visual analogue scale (Subjective overall impairment, coughing frequency, breathlessness, mucous congestion, color of sputum, consistency of sputum). The study is designed without any additional invasive or incriminating clinical examination. Aim of the study is to maintain the functional integrity of the tracheo-bronchial system after tracheostomy using LipoAerosol© resulting in a general therapeutic recommendation.
A Drug Interaction Study With Fluticasone Furoate/GW642444 Inhalation Powder and Ketoconazole
AsthmaA randomized two-way crossover study to determine whether concomitant administration of CYP P450 3A4 inhibitor ketoconazole and fluticasone furoate/GW642444M combination significantly increases the systemic effects and exposure to repeat dose fluticasone furoate and/or GW642444 in healthy subjects. Key assessments will include blood potassium, heart rate, blood pressure, QTc, serum cortisol and pharmacokinetic parameters, and safety including vital signs, ECGs, adverse event monitoring and laboratory safety tests, including blood glucose.
AT1R Blockade and Periodic Breathing During Sleep in Hypoxia
Sleep Disordered BreathingHypoxia2 moreSleep disordered breathing (SDB) is characterized by regular periods of no breathing (apnea) or low levels of breathing (hypopnea) and leads to repeated periods of low oxygenation, termed intermittent hypoxia that causes fluctuations in blood oxygen levels. This leads to increased peripheral chemoreflex sensitivity that is thought to occur through the stimulation of angiotensin-II, type-I receptors (AT1R) that are expressed primarily on glomus cells within the peripheral chemoreflex and ultimately results in long lasting hypertension. The goal of this study is to determine if AT1R receptor blockade can prevent the increase in chemoreflex sensitivity following one night of hypoxia and improve the severity of SDB.
The Role of Opioidergic Systems in Breathing Based Analgesia
PainThe purpose of this psychophysical and pharmacologic study is to determine if slow-breathing induced pain relief is mediated by endogenous opioids in response to intravenous (IV) administration of the opioid antagonist naloxone during noxious heat stimulation. We were also interested in disentangling the endogenous analgesic mechanisms supporting mindfulness-based analgesia.
Inspiratory Muscle Training in Nemaline Myopathy
Nemaline MyopathyInspiratory Muscle TrainingNemaline myopathy is a rare congenital myopathy. Respiratory failure is the main cause of death in these patients. The primary objective of this study is to determine the effect of a 8-week inspiratory muscle training program on respiratory muscle function in nemaline myopathy patients. The secondary objective is to determine respiratory muscle function in nemaline myopathy patients and its correlation with clinical severity and general neuromuscular function. The nemaline myopathy patients will be included in the first phase for a clinical characterization. From this phase patients will be selected for the second phase, which is a controlled before-after trial of inspiratory muscle training. The primary outcome is the change in maximal inspiratory pressure (MIP) after active inspiratory muscle training

Use of Masks on Metabolic Parameters and Inspiratory Muscle Strength During Aerobic Exercise
MasksThe purpose of this study will be to assess the effects of the use of masks on inspiratory muscle strength, metabolic parameters, heart rate, subjective perception of effort and the sensation of dyspnea before, during and after an aerobic test of 30 minutes long and a fixed load at lactate threshold. A randomized study of repeated measures will be carried out. A total sample of 35 active participants will be recruited. All participants will carried out a lactate threshold test and then 3 visits to the laboratory (separated at least 48 hours from each other) in order to perform 3 test of 30 minutes long without mask, with a surgical mask or with a FFP2 respirator (in a randomized order) at an intensity around lactate threshold intensity. Maximal inspiratory pressure, oxygen saturation, heart rate, blood lactate concentration, subjective perception of effort and dyspnea will be assessed before, during and after the 3 fixed intensity tests.
