This work is designed as a randomized clinical trial, in which the effects of a protocol of 12-week resistance training loading the Achilles tendon and low-energy focused extracorporeal shock wave therapy (ESWT) in patients with Achilles tendinopathy (AT) will be monitored. It is estimated that at least 40 patients will participate, randomly divided into two groups. Group A will be instructed to perform a training protocol in combination with ESWT according to selected parameters. Group B only completes the same training protocol.
The aims of this study are threefold. First, to investigate whether spinal nociceptive processing - represented here by the nociceptive flexion reflex (NFR) - is influenced by thoracic transcutaneous spinal direct current stimulation (tsDCS) in a spatially selective manner, i.e., whether effects are only observed for lower limb NFRs, but not for upper limb NFRs. Second, to investigate - in a double-blind, sham-controlled, within-participant design - whether anodal and cathodal tsDCS do affect the NFR in a polarity-dependent manner. Third, to investigate whether tsDCS effects observed on a spinal measure (NFR) are also observed in responses that are mediated supra-spinally, namely autonomic parameters and pain intensity ratings.
The goal of this multi-center clinical trial is to evaluate the effectiveness of MRI-based computer-aided diagnosis software (V1) for glioma segmentation, gene prediction, and tumor grading. Machine learning methods such as high-precision tumor segmentation and classification and discrimination modeling can further optimize the non-invasive molecular diagnosis and prognosis prediction. The main question it aims to answer is whether the software can predict the molecular type and the prognosis quickly and correctly. The results will be compared with the real-world clinical data double-blindly. Finally, form a set of user-friendly automatic glioma diagnosis and treatment systems for clinics.
This study will be conducted to evaluate clinical and radiographic success of Photodynamic Therapy for root canal treatment of primary molars in comparison to the standard root canal treatment.
The goal of this study is to test the usability and applicability of a mobile application which recommends recipes. We will recruit up to 52 vegan/vegetarian participants in Belgium, and provide them with an iDOO hydroponic plant growing unit (https://www.idooworld.com/products/idoo-20pods-indoor-herb-garden-kit-hydroponics-growing-sy stem-with-led-grow-light) as well as seeds and plant nutrients to grow certain herbs at home. Over a period of 17 weeks, participants will be asked to consume plants from the unit by following the recipes recommended by the app. The participants will then observe changes in their iron and vitamin B12 levels by following up with their GP and report the outcomes back to the researchers at three points during the study (week 0, week 6, and week 17). In addition, the participants will evaluate the usability of the app and the recipes recommended by the app.
Cancer is an important health problem in the world and in our country, and it ranks second among the causes of death in our country (20.7%). Chemotherapy, one of the most commonly used methods in cancer treatment, causes many physical and emotional symptoms while treating the disease. Nausea-vomiting is a common problem in cancer care, especially in patients receiving chemotherapy. In the literature, there are studies examining non-pharmacological interventions for the prevention and management of nausea and vomiting in patients receiving chemotherapy, and it is seen that the interventions are mostly within the scope of complementary and alternative approaches. Patients receiving ambulatory chemotherapy may experience anticipatory nausea in particular, and this is likely to affect the individual's comfort level. In studies conducted in the field, the comfort level of cancer patients receiving chemotherapy was determined as moderate. Today, mandalas are used effectively in the field of art therapy. The possibility of using mandala in all age groups has contributed to the treatment process of different diseases and disorders, and its effectiveness has been presented to the scientific world with many researches around the world. In adults, the mandala has been used both in the treatment of psychiatric disorders and as a tool to observe the effects of treatments. Art therapy including mandala drawing has significantly reduced the severity of trauma symptoms in individuals with anxiety disorders and post-traumatic stress disorder. In the study of Zhao & Tang (2017) it was determined that mandala drawing therapy reduced the anxiety of cancer patients. If the reduction of nausea-vomiting affects the comfort level and the person is relieved, a more effective treatment environment is created and the quality of life of the person is increased. In the literature, very limited studies have been reached on the use of the mandala drawing technique in cancer patients. National and international research examining the mandala drawing technique, especially in patients receiving ambulatory chemotherapy, could not be reached. The aim of this study is to determine the effect of mandala drawing technique on nausea-vomiting and comfort level in patients receiving ambulatory chemotherapy. It is anticipated that the study to be conducted will contribute to nursing interventions in the cancer care process and lead to the planning of new research on the subject.
Lung transplantation is a life-saving therapy for patients with advanced lung disease, however, necessitates the use of life-long immunosuppressive therapy for the prevention of acute and chronic rejection. The backbone of immunosuppression is the calcineurin-inhibitor class, with tacrolimus being the preferred drug due to its potency and improved side-effect profile. Nevertheless, tacrolimus is associated with several side effects including increased risk for infection and malignancy, tremors, headaches, seizures, hypertension, leukopenia and renal dysfunction. In fact, by 6 months post-transplant, 50% of patients will have a 50% decline in eGFR and by 5 years post-transplant ~10% of patients will have advanced renal disease that may require renal replacement therapy and/or kidney transplantation. Tacrolimus induces a nephropathy in two ways- acute calcineurin inhibitor nephrotoxicity (CIN) is mediated by afferent arteriolar vasoconstriction, whereas chronic CIN is due to interstitial nephritis and fibrosis. Immunosuppressive regimens that spare or dose-reduce calcineurin inhibitors have been shown to have a modest impact on preserving renal function, but are limited by timing. Although most studies support implementing renal preserving protocols early on, this is balanced by the potential for acute cellular rejection, antibody mediated rejection and anastomotic dehiscence. Long-acting Tacrolimus (LCP-tacrolimus) may have the potential to bridge the balance of providing potent immunosuppression, while sparing renal function, due to the better systemic dose levels and improved concentration/dose ration achieved with it compared to IR-tacrolimus, evidenced in the renal transplant population. There is limited experience with LCP-tacrolimus in lung transplantation. Several case reports chronicling the late conversion from IR-tacrolimus to LCP-tacrolimus due to absorption issues or side-effect intolerance, have demonstrated safety and tolerability. The investigators seek to determine whether early use of LCP-tacrolimus in lung transplant recipients following the index hospitalization is acceptable, and propose a single-center prospective, randomized, controlled pilot study of early-use LCP-tacrolimus in lung transplant recipients to assess safety, tolerability and side-effects of LCP-tacrolimus.
Head-and-neck cancers (HNC) account for 4 percent of cancer diagnoses in the United States and for more than 66,000 annual cancer diagnoses. The prevalence rate of HNC among Veterans is 150% higher than the rate in the general population. Together with smoking, alcohol drinking is a major risk factor for HNC, responsible for approximately one-third of the cases worldwide. Overwhelming evidence from population-based studies show that alcohol drinking significantly increases the risk of recurrence of the primary HNC and of second primary malignancies, as well as negatively impacts HNC survivors' psychosocial health. Hence, several organizations (i.e., American Cancer Society, American Society of Clinical Oncology, and the World Cancer Research Fund) have issued guidelines recommending that individuals with HNC reduce or avoid alcohol altogether. Despite these recommendations, a substantial proportion of HNC survivors continue to use alcohol. The overall goal of the proposed research is to: 1. Adapt an existing evidence-based text message alcohol cessation intervention for HNC survivors in both civilian and VA settings (i.e., at two sites, Northwell Health and the Brooklyn VA Medical Center); and 2. Preliminarily evaluate, in a two-arm pilot RCT, the acceptability and preliminary efficacy of the intervention, as well as feasibility of conduct a future RCT. The investigators hypothesize that: - H1: The tailored text-message intervention will be 1) feasible to evaluate in a large-scale RCT, defined as achieving an enrollment rate of ≥70% in this pilot; and 2) acceptable to participants, defined as a score ≥4 on a 5-point Likert scale ranging from "not at all" to "extremely" acceptable. - H2: Compared to the control condition of alcohol assessment and feedback (AF), the tailored text messages will result in a 30% increase in cessation among survivors (assuming also a 20% increase in cessation in the AF arm).
The aim of this study is to evaluate effects of clear aligners versus fixed appliances on occlusion after treatment of mild anterior crowding a T-scan study.
Many post COVID-19 patients suffer from cognitive deficits, even after 1 year after hospitalization. These complaints have a huge impact on psychological well-being and quality of life. In rehabilitation programs in the Netherlands, most interventions are based on physical therapy or learning how to cope with fatigue and low levels of energy. In former studies computerized training of cognition in other populations has been proven to be effective. Knowledge on the effect of computerized training on attention and working memory in patients suffering from COVID-19 is urgently needed, and may contribute to more evidence-based rehabilitation programs for these patients. Therefore the effectiveness of computerized training of attention and working memory in post COVID-19 patients with cognitive complaints will be studied in this study.
