NCT01454895
The purpose of this project is to compare the effectiveness of several approaches to influencing hearing protector use. The goals of this study are to further develop an intervention to promote farmers' use of hearing protectors, and compare the effectiveness of the developed intervention with two alternative approaches to influencing hearing protector use behavior, delivered in various combinations. This study will determine if significant change in hearing protection use can be achieved in a one-shot web-based or protector-supply intervention. Results will determine the need for future program modifications, e.g., inclusion of booster(s).
NCT00214071
Obstructive sleep apnea (OSA) is a medical problem whose importance is increasing in recognition and awareness. OSA is associated with the development of hypertension and other cardiovascular diseases (1,2). OSA has pathophysiologic characteristics that are known to negatively impact immune function. Both sleep deprivation and hypoxia, hallmarks of OSA, impair immune responses (6,8,11). In addition, patients with OSA are frequently obese and obesity may be associated with increased chance of infections and immune impairment (14,15). Adipose cells are known to secrete cytokines and hormones that are involved in the immune response such as leptin, tumor necrosis factor alpha and interleukin-6 (16-19). Thus, it seems very likely that OSA may impact antigen-specific immune responses. Although it is known that characteristics of OSA impact immune function, it is not known what effects clinical OSA has on immunity. The central hypothesis of this application is that that patients with obstructive sleep apnea will have attenuated cell-mediated and humoral immune responses to influenza vaccine compared to matched control subjects. Our hypothesis has been formulated on the basis that patients with OSA are sleep deprived and experience repeated hypoxemia that negatively impact both humoral and cell-mediated immune responses.
NCT01720017
The overall purpose of this study is to assess the impact of preclinical airway manikin training using the Airtraq Avant and Wireless Monitor System under simulated difficult airway conditions (c-collar and swollen tongue) on the clinical learning curve of using the device/system in airways with predictors for difficult intubation. The investigators hypothesize that the clinical learning curve in airways with predictors for difficult intubation will be shorter for study subjects (operators) who undergo preclinical manikin training under simulated difficult airway conditions compared to Study subjects (operators) who do not receive this training. The clinical learning curve is characterized by procedure times and first attempt success rates on successive uses of the Airtraq Avant and Wireless Monitor System in patients with at least one predictor for difficult intubation.
NCT00313092
The aim of the study is to determine if plasma matrix-metalloproteinase activity can predict glaucoma in patients with OSAS and if the level of plasma matrix-metalloproteinase activity will decrease after one month of nCPAP-treatment.
NCT01108328
The objective of the study is to compare subjective appetite ratings and after-meal and 24 hour blood glucose levels within overweight and obese female subjects consuming either a standardized 3 day low calorie diet supplemented with a viscous fibre known as PGX (treatment) or a rice flour (placebo control). Each treatment phase will be 3 days in length and separated by 3 week washout phase, so subjects will also be acting as their own control. Subjects will be randomized to either start with the low calorie diet with PGX or the low calorie diet supplemented with rice flour. We hypothesize that the 3 day LCD with PGX will elicit an improved appetite score compared to the 3 day LCD supplemented with the rice flour placebo control.
NCT00767793
The purpose of this study is to evaluate the safety and tolerability of INS117548 ophthalmic solution.
NCT01517607
This non-interventional study examines whether the patient's level of information and the consideration of the patient's preference have a positive effect on the compliance and thus also on the therapeutic success.
NCT02238041
The primary purpose of this Study is evaluation of the safety and accuracy of the GlucoClear CGM System.
NCT01409421
The investigators are studying motivational interviewing (MI). MI is a counseling method to help people adopt healthy behaviors. The investigators will test whether MI improves patients' accurate use of glaucoma eye drops. The investigators will train eye clinic staff called glaucoma educators to use MI. Up to 250 patients at 3 clinics will be recruited. All patients will receive their usual eye care. Based on chance, some patients will also be supported by a glaucoma educator. The groups will be compared on medication adherence using micro-electro-mechanical system(MEMS). MEMS are electronic bottle caps that track when a medication bottle is opened. Patients will be aware that their medication use is tracked. The groups will also be compared on treatment value, outcomes, and cost. The investigators will also collect data on variables that may predict medication adherence.
NCT01865435
Actually, there is an increasing number of arguments for a premature origin of chronic adult's diseases, as the chronic obstructive pulmonary disease (COPD). Several factors interacting with the foetal or postnatal lung growth are associated with early and long-lasting respiratory functional changes susceptible to contribute very significantly to the arisen of a COPD in the adulthood. It is possible that these situations reflect phenomena of premature cellular senescence, recently involved in the physiopathology of the COPD. An in utero exposition to cigarette smoking is one of these situations, because it is known to induce, not only functional respiratory changes, but also multiple diseases in the child which could testify of cellular ageing phenomena. Our project aims to demonstrate that in utero smoking is associated with markers of premature cellular senescence in newborn children The study will be driven in human newborn child's, with comparison of the length of the telomeres in circulating lymphocytes (umbilical blood is collected), according to the exposure in in utero smoking and also according to the degree of hypotrophy. This study will be a pilot study completed by an animal experimental study.
NCT01242111
This multicenter, open-label extension study is designed to assess long-term efficacy and safety of 2.0 milligrams (mg)/kilogram(kg)/week of BMN 110 in patients diagnosed with Mucopolysaccharidosis IVA (MPS IVA). Patients with MPS IVA, who enrolled in a prior BioMarin sponsored clinical study of BMN 110 (NCT00884949; Study Identification Number MOR-002), were eligible to enroll in this study (except patients who enrolled in NCT01275066; Study Identification Number MOR-004).
NCT00397384
This phase I trial is studying the side effects and best dose of erlotinib hydrochloride when given together with cetuximab and to see how well they work in treating patients with advanced gastrointestinal cancer, head and neck cancer, non-small cell lung cancer, or colorectal cancer. Erlotinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Monoclonal antibodies, such as cetuximab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Erlotinib hydrochloride and cetuximab may also stop the growth of tumor cells by blocking blood flow to the tumor. Giving erlotinib hydrochloride together with cetuximab may kill more tumor cells.
NCT02561780
This study examines the effectiveness of a school based mental health literacy intervention for high school students, on improving mental health knowledge and reducing stigma. Twenty-four high schools in the regional area of Ottawa, Canada were randomly assigned to either the curriculum or control condition at a two to one ratio. The educational curriculum was integrated within grade 11 and 12 Provincial "Healthy Living" courses, delivered by teachers, and replaced existing educational content on mental health.
NCT02561910
The effectiveness of laparoscopic inguinal hernia repair still remains unclear. During a one year period a total of 1208 inguinal hernias in 952 patients were consecutively operated using the laparoscopic technique by a total of 11 general surgeons in daily clinical routine. Laparoscopic hernia repair in the TAPP technique seems to have the potential to become the standard procedure in inguinal hernia repair in future.

This study will evaluate the IOP lowering effect of SLT following the topical administration of one of the following: prednisolone 1%, ketorolac 0.5% or artificial tears.
NCT00826566
Nowadays it has become evident that a chronic systemic inflammation is present in patients suffering from chronic obstructive pulmonary disease (COPD). The role of the nuclear enzyme poly(adenosine diphosphate-ribose)polymerase (PARP) as a key mediator within these systemic inflammatory processes as well as in COPD associated exercise intolerance and muscle weakness could recently been identified. The attenuating effect of dietary ingredients with PARP inhibiting activity on systemic inflammation was supported by data from in vitro and in vivo studies, from other groups as well as from our own lab. We identified several caffeine metabolites as potent inhibitors of the most abundant PARP-isoform PARP-1 in-vitro, in animal models as well as in ex-vivo experiments with whole blood from COPD patients. However, clinical data with respect to their anti-inflammatory effects in COPD patients are currently not available for none of these substances. Therefore, the current clinical pilot study is intended to establish for the first time clinical data (proof of principle) on the anti-inflammatory potential of caffeine metabolites.
