Filter by:Malaria, schistosomiasis and ancylostomiasis are three parasitic diseases which affect hundreds of millions of people and are an important cause of global mortality and morbidity. For the control of these poverty related parasitic diseases, and to complement chemotherapeutic strategies, accurate and accessible diagnostic procedures play a crucial role. In recent years, innovative smart mobile technologies have been applied for detection and identification of cultured parasite species, which is basically based on sample imaging and parasite morphology identification. Promising advances have been made with this technology and coupled with its small size, low cost and easy to manipulate, makes it suitable for point of care diagnostics in low resource setting. The aim of the proposed explorative study is to further validate sensitivity and specificity of each of the developed devices, using besides microscopy a range of more advanced reference tests.
Rationale: This protocol describes a study on the local tolerability of dry powder hydroxychloroquine using the Cyclops in healthy volunteers. Objective: - Primary objective is to assess the local tolerability of dry powder hydroxychloroquine sulphate via the Cyclops at different dosages. - Secondary objective is to investigate systemic pharmacokinetic parameters of dry powder hydroxychloroquine sulphate via the Cyclops at different dosages. Study design: single center, ascending dose study Study population: twelve healthy volunteers Main study parameters/endpoints: The local tolerability of the inhalation of dry powder hydroxychloroquine sulphate (5, 10 and 20 mg) defined by a lung function deterioration (a drop of forced expiratory volume in 1 second (FEV1) of >15%), cough, or any other reported adverse event. Pharmacokinetic parameters will be derived from calculated actual inhaled dose (dose minus remainder in inhaler after inhalation) and in blood samples drawn pre-dose, at 0.5 and 2 and 3.5 hrs after inhalation. The inspiratory parameters during the inhalation maneuver are critical to explore predictors for drug exposure. The following parameters will be measured/calculated: dPmax (maximum pressure drop), Vi (inhaled volume), Ti (total inhalation time), PIF (peak inspiratory flow rate), MIF (mean inspiratory flow rate) and the FIR (average flow increase rate between 20% and 80% of PIF). Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The participants included are healthy volunteers. They will receive three different doses of hydroxychloroquine sulphate using the dry powder inhaler (DPI) with (at least) seven days in between doses. Before using the dry powder inhaler (DPI), they will receive instructions and their inspiratory flow will be tested. To investigate local tolerability, lung function tests will be performed, and the occurrence of adverse events will be scored. Furthermore, before each test dose an indwelling cannula will be inserted and blood samples will be taken before and after each test dose. Four blood samples will be collected with each inhaled dose. Finally, five ECGs will be obtained to monitor for QT prolongation, one at the screenings visit, one at base-line and one after each inhalation.
Preliminary reports have been received from several sources that the periodic inhaling of the nebulized mist from water that has a heightened level of kinetic activity has quickly (less than 2 days) lessened the severity of symptoms in Covid-19 infected patients. On at least several occasions, a repeat PCR test performed several after inhaling a particular water-based product was negative. There are no perceived adverse effects from inhaling the water mist by using a nebulizer or humidifier. It is important, however, to validate these preliminary findings and to include the inhaling of the mist from water, which does not have an elevated level of kinetic activity. This will be by performed in a patient-blinded manner by sequentially inhaling the two types of water over consecutive 2-day periods with Covid-19 testing at the end of each of the two day periods. Participants will be randomized as to whether they are to inhale the mist from the test or the control water.
aim of this cross-over study is to compare sedation with insufflated sevoflurane and intravenous sedation for pediatric radiotherapy patients
Clinical trial on eosinophil-guided time-updated person-specific reduction of inhaled corticosteroid (ICS) therapy and prophylactic azithromycin therapy in patients with severe or very severe chronic obstructive pulmonary disease (COPD) receiving long-acting b-agonist (LABA) / long-acting muscarinic receptor antagonists (LAMA) / ICS treatment.
The aim of this study is to evaluate the effects of inspiratory muscle training program in inspiratory muscle endurance, breathlessness, inspiratory muscle strength, functional capacity and quality of life in patients with interstitial lung disease. Patients are evaluated before the inspiratory muscle training and after 8 weeks of training.
One of the most frequent surgical procedures in the pediatric population is circumcision, following which postoperative pain could be stressful. Usually, the most common approach is combining regional anesthesia techniques such as landmark dorsal penile nerve block (DPNB) with general anesthesia (GA). The hypothesis of this study investigates ultrasound-guided DPNB plus sedation in spontaneous breathing.
Objective: To determine the effect of breathing exercises on certain physiological parameters, sleep quality and vitality in the elderly. Method: In this randomized controlled, experimental study, pre and post tests were applied to 26 elderly participants in the intervention group and to 25 elderly patients in the control group. The intervention group underwent breathing exercises for 30 minutes at the same time of the day, three days a week for three months (pursed-lip breathing exercise, deep breathing exercise, coughing exercise), while no such exercise was carried out by the control group. Pittsburg Sleep Quality Index, the Subjective Vitality Scale, spirometer, sphygmomanometer and pulse oximetry device measurements were used for the collection of data. The data was evaluated with an independent sample t-test, a paired-sample t-test and a two-way repeated measures ANOVA.
Bioequivalence study between two inhaler products of fixed dose combination of fluticasone propionate and salmeterol xinafoate inhalation powder
Maximal oxygen consumption, VO2max, is the gold standard to evaluate human aerobic fitness, which stands for the maximal capacity of cardiorespiratory system and musculoskeletal system to transport and utilize oxygen. Previous study showed that there is significant correlation between maximal oxygen consumption from cardiopulmonary exercise test and strength and endurance of lower extremities. In people with sedentary lifestyle, they often limited by the lower limb muscle performance during cardiopulmonary exercise test. Their breathing patterns are more irregular than athletes during cardiopulmonary exercise test. However, there is no study comparing the activation pattern of respiratory muscles between these two groups. Whether the breathing pattern in people with lower exercise capacity is less efficient under exertional activities still unknown. The purpose of this study is to investigate the relationship between maximal oxygen consumption and inspiratory muscle activation pattern in healthy adults.
