NCT ID: NCT03578510 Completed - Clinical trials for Patients With End Stage Renal Disease on Hemodialysis

Effect of Plasma Sodium Concentration on Blood Pressure Regulators During Hemodialysis

Start date: September 17, 2012
Phase: N/A
Study type: Interventional

Intradialytic hypotension (IDH) is a frequent and serious complication that may occur during hemodialysis treatment. The investigators and others have shown that the Hemocontrol biofeedback system is associated with improved hemodynamic stability. Hemocontrol is a technique that guides the patients' blood volume along a pre-set trajectory by continuously adjusting the ultrafiltration rate and dialysate conductivity. In a recent pilotstudy, the investigators found significantly higher plasma vasopressin levels during the first hour of dialysis with Hemocontrol in comparison with standard hemodialysis. Increased vasopressin levels may contribute to intradialytic hemodynamic stability during hemodialysis by enhanced vasoconstriction. These results, however, did not prove directly that the improved hemodynamic stability with Hemocontrol is indeed caused by higher initial plasma vasopressin levels. Alternative explanations might be that 1) the higher initial plasma sodium levels with Hemocontrol dialysis enhance activity of the sympathetic nervous system directly, causing vasoconstriction and thereby improved hemodynamic stability and/or 2) that the higher initial plasma levels of sodium in Hemocontrol inhibit the release of nitric oxide by the vascular endothelium. Another goal of this study is to investigate whether vasopressin is removed with hemodialysis.

NCT ID: NCT03525236 Completed - Cancer Clinical Trials

The Oncoflavour Study

Start date: June 19, 2017
Phase: N/A
Study type: Interventional

Oral nutritional supplements (ONS) are often prescribed for malnourished patients to help improve nutritional status. Commonly in cancer patients taste and smell alterations and side effects of treatment can affect the palatability and compliance to ONS. A variety of flavours and styles are available of ONS however research of the palatability of these in cancer patients is limited. This study aims to evaluate specific flavours created based on the taste changes occuring during treatment. We aim to evaluate the patient liking and evaluation of 5 flavors in 3 different types of flavour-sensations: - Warming/spicy sensation: to trigger the senses and bring new sensations - Cooling/fresh sensation: to have a fresh mouthfeel and lighter base perception - Neutral: to avoid that patients experience additional flavour and let them the opportunity to mix it with other food

This study will also determine the single-dose PK of total radioactivity, TAK-954 and its metabolites where possible.

NCT ID: NCT03498053 Completed - Cigarette Smoking Clinical Trials

Smoking Topography Study 2018

Start date: December 12, 2017
Phase: N/A
Study type: Interventional

Rationale: The World Health Organization Framework Convention on Tobacco Control (WHO FCTC) aims for a regulatory strategy including the regulation of the contents of tobacco products (Article 9). Cigarette smoke includes more than 7000 chemicals which are harmful and cause tobacco-related diseases. In the future, regulation of these harmful cigarette constituents should be based on more chemical classes, as the WHO suggested. However, in order to introduce such class-based regulation, a scientific base is needed to define upper limits of allowed amounts of chemicals (groups) in cigarette smoke emissions and to ensure decreased harmful health effects due to cigarette smoking. To date, the causality between human exposure to specific cigarette smoke compounds and the harmful effects is unknown. The first step in closing the gap in knowledge between cigarette smoke exposure and developing tobacco-related diseases includes a proper determination of human exposure to cigarette smoke chemicals. This includes measuring smoking topography and inhalation. Smoking topography is how the smoker smokes the cigarette (puff volume, duration, flow etc). The goal is to link smoking behavior to smoke exposure, for 2 different cigarette brands. The participants will smoke their 'normal' brand Marlboro (experimental day 1) after which they receive the low TNCO (tar, nicotine and carbon monoxide) Marlboro Prime to smoke at home. A week later the experimental day (day 2) is repeated with this cigarette. On the last experimental day (day 3), the participants will smoke the Prime cigarette while the ventilation holes of this low-TNCO cigarette are taped. Afterwards, the personal smoking profiles of the participants, and thus their individual exposures, will be mimicked in the lab using machine smoking. The observed smoking topography and inhalation parameters together give information about the exposure to smoke toxicants. In addition, this study is also designed to measure biomarkers of exposure in body fluids of smokers, such as nicotine and the most abundant cigarette smoke chemicals and their metabolites. Objective: We want to find out whether the individual habitudinal smoking topography of a smoker smoking his usual brand, and the changes between cigarettes over the day, can be compared to that of smoking a low-TNCO or high nicotine cigarette (i.e. the Marlboro Prime and Red Sun). In addition, differences in inhalation patterns are investigated. Next to that, the exposure will be connected to the nicotine and carbon monoxide levels in blood and/or urine. Also smoke toxicants (and metabolites) in exhaled air, saliva, urine and blood of smokers are determined. Study design: This prospective observational study monitors smokers in their habitudinal smoking during the day (for 10 hr) while smoking Marlboro, Marlboro Prime and Marlboro Prime taped cigarette, while during the day bodily fluids are sampled at several time points. Study population: This population consists of 18 Caucasian, healthy, adult males, aged between 25-34 years old. Participants should be used to smoke Marlboro (red/regular) for at least 3 years with a daily average of 13 to 25 cigarettes (about a package every day). Nature and extent of the burden and risks associated with participation, benefit and group relatedness: The participating smokers smoke according to their habitudinal smoking pattern, and are therefore not increasingly exposed to the harmful health effects of cigarette smoking. The invasive part of the study is their stay for 3 days (and 1 night when wanted) in a hotel, and the sampling of blood, saliva, urine and exhaled air.

NCT ID: NCT03428789 Completed - Breast Cancer Clinical Trials

Nerve Coaptation in DIEP Flap Breast Reconstruction

Start date: September 2015
Phase: N/A
Study type: Observational

The sensory recovery of the breast remains an undervalued aspect of breast reconstruction and surgical reinnervation is not regarded as a priority by most reconstructive surgeons. A prospective study was conducted of all patients who underwent either innervated or non-innervated DIEP flap breast reconstruction in Maastricht University Medical Center and returned for follow-up between September 2015 and July 2017. Semmes-Weinstein monofilaments were used for sensory testing of the breast. This study showed that nerve coaptation in DIEP flap breast reconstruction resulted in a significantly improved sensation of the reconstructed breast compared to non-innervated flaps.
