Filter by:With the HOBBIT trial, the investigators want to develop a technology that allows volunteers to hold their breath for a long time. This technique will then be taught to patients with breast cancer to be able to hold their breath long-term during the irradiation. After all, research has shown that the heart is in a better position when the patient enters her breath after a deep inhalation, as a result of which there is less unwanted radiation of the heart. To develop this technique the investigators use healthy volunteers, who are asked several times to hold their breath as long as comfortable. Before the respiratory arrest the investigators allow these volunteers to hyperventilate, administer oxygen and cause hyperinflation of the lungs. The volunteers come back four times, on four consecutive days. The first day they receive a short training. Afterwards oxygen is administered for a few minutes while the volunteers are asked to hyperventilate. Afterwards, by using the learned technique, they must hold their breath for as long as possible, comfortably. They should hold their breath 3 times in total with a short break in between. The following days there is always a change in the preparation protocol, compared to the previous study. Different parameters in the protocol will be changed for different groups of volunteers, this is based on randomization. In this way the effect of different parameters in the preparation of the AHS can be investigated. The investigators will use this information to develop a new protocol for extending the duration of breathing to two minutes and thirty seconds for use during radiotherapy treatment. The method for finding the optimal technique is iterative optimization. This method follows a process of development, testing, feedback and redevelopment cycles. Iteratively, these cycles of development use the prior research to further elaborate the most promising discoveries and drop paths that do not produce the desired result. During the development The investigators listen to the input of different people: doctors, nurses, support staff, engineers and the participants, to guarantee the usability of the technique on the radiotherapy device. Once the researchers think they have found a solution that meets all the conditions, a group of untrained volunteers are asked to implement the technique. With this the investigators validate the technique for later use in breast cancer patients.
An open clinical trial not randomized, multicentric. This study search to evaluate vitamin D supplementation efficacy at high dose (UVEDOSE, colecalciferol, oral solution at 100 000 UI) of vitamin D on day 1 of each cycles for breast cancer treated adjuvant chemotherapy. A calcium supplementation will be prescribed in parallel. An initial dosage of 25OH vitamin D rate will be done and a vitamin-calcic dosage will done on day 1 of every cycles of chemotherapy
Hepatitis C viral infection is a major health problem in Egypt. The management of breast cancer patients is often complicated by the presence of associated HCV infection. This study aims at investigating the epidemiological association of the two conditions. It will also investigate the possible correlation with treatment outcome.
The objectives of this pilot study are to determine the feasibility of a community-based moderate intensity resistance exercise training (RET) program in combination with an art sculpting class on body image in breast cancer survivors (BCS). The protocol will be measuring recruitment; attendance; cost tracking; body image distress; body image appreciation; and muscular strength. Participant feedback on the intervention will be collected through a final focus group. Additionally, cognitive interviews will occur prior to the intervention, where participants will be asked to "think-out-loud" as they answer the Body Image Scale for Cancer questionnaire. The purpose of this interview technique is to gain a deeper understanding of the participants' thought process behind choosing each answer. The proposed pilot study will be a single prospective before and after study that will help inform a future large-scale project. A minimum sample of 12 subjects will be recruited. The Health Research Ethics Board of Alberta Cancer Committee will approve this study. Participants will participate in RET biweekly for 12 weeks and the sculpting class weekly for 8 weeks. After the first week of RET, the art class will begin. Both the RET and sculpting class will be between 1-2 hours in length. Analyses: Quality of life, fitness testing and body image scales will be administered before and after the intervention. Cognitive interviews will occur once before the intervention has started and a final focus group will occur at the end of the intervention to get participant feedback on the effectiveness of the program
This phase I, first-in-human (FIH) study is open-label, non-randomised and non-placebo-controlled. The study is designed to evaluate the safety, tolerability and pharmacokinetics (PK) of a single intravenous dose of SN132D in approximately 24 patients with breast and pancreatic cancer. Magnetic resonance imaging (MRI) will be performed pre- and post-infusion of SN132D.
A feasibility study, randomising to either 10 or 20 mg of tamoxifen. The primary aim is to identify the time to mammographic density change and piloting the procedures. It is known that a density change is seen after 12 months of 20 mg of tamoxifen, but the clinical experience indicates that an effect of drugs influencing mammographic density could be seen already after a few months. The second aim is to evaluate if there is a density change from 10 mg of tamoxifen equivalent to 20 mg.
The aim of the present study is to investigate the effect of intravenous anesthetics versus the administration of volatile anesthetics on stress and pain levels during autologous fat transfer for breast reconstruction in a Day Care Center.
Functional Compressive Bandage (ECF) is a widely used therapeutic resource in the control of lymphedema resulting from the treatment of breast cancer, however, the effects inherent to the technique depend on the quality of the application. The aim of the study is to evaluate the reliability, reproducibility, and efficiency of treatment with different techniques in two studies. The first step aims to evaluate the reliability and reproducibility of the technique. The analysis of the pressure exerted by the four-layer bandage, applied by two evaluators previously trained and familiar with the ECF technique will perform the evaluations on the same volunteers in two moments, with an interval of one week between them. The intraclass correlation coefficient will be used to determine intra- and inter-examiner reliability, with its respective 95% confidence interval, standard error of measurement and minimum detectable change. The second stage aims to verify the efficiency of different ECF techniques in the functionality and circulation of the upper limb affected by lymphedema. This step is being performed by a single evaluator, and the ECF efficiency tested by the random application of two different techniques (spiral and eight), with a seven-day interval, and pressure assessment in mmHg. Upper limb functionality analysis is being performed using the Jebsen Taylor test performed before and with ECF on both limbs. The evaluation of the influence of the bandage in the circulation evaluated by Doppler ultrasound, before and after the test application. Member dominance assessed using the Edinburgh inventory.
A randomized multi-arm study evaluating the safety and efficacy of palbociclib and anastrozole with or without nivolumab in participants with ER+/HER2- breast cancer
This study evaluates the acute effect of aerobic exercise and yoga on pain, plasma levels of endocannabinoids, and mood (i.e., mood disturbance and anxiety). Participants will complete three separate sessions on different days. The first session is a familiarization session in which participants complete questionnaires and are familiarized with the experimental protocols. During the second and third sessions, outcomes are measured before and after the participants complete either 44 minutes of moderate aerobic exercise (i.e., walking on a treadmill) or 44 minutes of yoga.
