View clinical trials related to Taste Disorders.
Filter by:Taste disorders in cancer patients during chemotherapy could be consider as multifactorial disease, it is related with changes of food consumption. Approximately 36-69% of the patients under chemotherapy suffer oral toxicity or dysgeusia A prospective case- only observational study was conducted in patients of the Hospital General de México for two years. A self-reported taste survey was used, and patients scored their results in a Likert scale.
Evaluating the smell and taste perceptions of patients hospitalized in the intensive care unit with suspicion of Coronavirus disease-19 diagnosis with a survey study
This is a prospective monocentric observational study with the aim of investigating the demographic and clinical factors related to the smell and taste disorders in patients with Severe Acute Respiratory Syndrome - Coronavirus - 2 (Sars-Cov-2) infection.
A novel coronavirus SARS-CoV-2 HAS arose in 2019 in Wuhan, China. Beside the classical semiology of this infection, numerous patients described olfactory and teste disorders. These symptoms are not described in this coronavirus, neurotropism of coronaviridae has been documented before. The aim of the study is to evaluate prevalence of anosmia and dysgeusia (olfactory and taste disorders) in coronavirus diagnosed patients and compare with different clinical conditions. The second endpoint is to evaluate the duration of these symptoms in order to better understand the semiology of this infection.
The ONCOFOOD project aims to design and develop new innovative food solutions for cancer patients, taking into account not only their nutritional requirements but also their sensory changes, promoting eating pleasure and preventing malnutrition. Research involving cancer patients but also their families and health care professionals is a key element of this approach to ensure the success of the developed products for the target group.
Cancer patients are at high risk of undernutrition, which is generally more pronounced for solid tumours (upper digestive tract, Ear Nose and Throat (ENT), bronchial tubes). This undernutrition leads to major weight loss and cachexia, and may represent the first sign of a call for a diagnosis of cancer. Cancer-related undernutrition is multi-factorial origins and has multiple consequences. Chemotherapy treatments can induce various adverse effects in patients, including sensory disturbances at the beginning of treatment in addition to disturbances that may already be present before any treatment. The alteration of taste and odour, observed in 86% of patients, can induce a change in food preferences, promote the development of aversions, and therefore, lead to a significant reduction in the pleasure of eating. Loss of appetite, decreased food intake and the development of aversions to certain foods are situations experienced by a large proportion of patients treated with chemotherapy. The assessment of taste disorders in patients treated with chemotherapy is established through the use of questionnaires, interviews and taste tests. Changes in the perception and identification of salty, sweet, bitter and sour flavours are common in patients treated with chemotherapy. As regards food products, patients report developing olfactory hypersensitivity mainly for food of animal origin, in particular for odours of fish, frying, cheese and eggs. The CANUT project aims to study the effect of pathology and chemotherapy on gustatory and olfactory mechanisms, and in particular on interindividual differences in the perception and appreciation of food. In order to monitor the evolution of patients' eating habits over time, the diet-related quality of life questionnaire (CANUT-QVA) was constructed from items selected from the Well-being related to Food questionnaire (WELLBFQ) after eliminating questions that were too general or expressed in terms of importance to use perception-related responses as a priority. After this part, an evaluation of the 9 dimensions of the CANUT-QVA questionnaire will be performed.
Personalized nutrition is one of the most up to date trends in human nutrition and gains much interest of general public and scientists as well. Although we have gained some knowledge on gene-trait associations, the real effectiveness and usefulness of genotype-based nutritional recommendations is unknown. Many personalized nutrition companies are on the market today, some of them use personalized nutrition based on genotype analysis. For this reason, scientific basis of this approach should be clarified. Our project can thus increase knowledge which can be applied in dietary counseling practice. Although we focus on increase vegetable and fruits intake, the study is designed as a proof of concept.
- Assess gustatory thresholds among a sample of depressed Egyptian adults (age from 20 to 50 years old) under anti-depressants therapy ( for at least 3 months) using filter paper disc(FPD) method through a scoring system. - Determine the taste intensity at supra-threshold among these patients using a psychophysical method through a scoring system. - Identify possible modulators for developing gustatory dysfunction among these patients using a questionnaire ( appendix) with a binary measuring unit (yes/no).
Metallic taste in head and neck cancer is widely under-estimated in the literature. Its causes are multiple and poorly defined. Though it has a strong impact on the nutritional status. The main objective of the TORCAD project is to test the hypothesis that intraoral lipoperoxidation is associated to metallic taste onset before, during and after treatment of head and neck cancer (HNC). The secondary goals are to evaluate the involvement of others physiopathological factors in metallic taste: (i) additional chemical modification in the saliva; (ii) release of inhibition of the facial nerve on the glossopharyngeal nerve; presence of an intraoral electric current; food pleasantness and acceptability; quality of life.
During conditioning with chemotherapy and radiotherapy for the transplantation of hematopoietic stem cells (HSCT), oral changes, such as mucositis, xerostomia infections and dysgeusia may occur. Low level laser therapy is used to minimize the intensity of the lesions, prevent ulcerations in the mucosa, and diminish the time of healing. To verify the efficacy of low level laser therapy in the prevention of dysgeusia in patients undergoing allogenic HSCT and detect the frequency of dysgeusia, the flavors most changed, and the association of these changes with the clinical conditions of the patient. The study sample will be composed of 80 patients selected at the Hematopoietic Stem Cell Transplantation Center of the "Hospital Israelita Albert Einstein". The patients will be randomized and distributed into two groups: Placebo Group (n=40) - submitted to the routine laser therapy protocol in addition to simulated laser irradiation on the taste papillae; Test Group (n= 40) - submitted to the same laser therapy protocol as that of the Placebo Group, however, laser irradiation on the taste papillae will be effective. Daily intraoral exam will be performed in all the patients to evaluate mucositis, xerostomia and depapillation. The taste acuity test will determine the function of taste, using samples with the four basic flavors. This will be performed on the first day of conditioning (T0), during the stage of neutropenia (T1), at the time of discharge after transplantation (T2) and 100 days after transplantation (T3). A questionnaire will also be applied to evaluate the impact of changes in taste, smell and xerostomia on the quality of life. Our hypothesis is that the laser irradiation on the lingual papillae would help to prevent the changes in the cells of the taste papillae, preserving their morphology and function, which may attenuate the change in sense of taste and have a positive impact on the quality of life of patients during transplantation.
