Effect of Dried Miracle Berry on the Olfactory-gustative Perception in Malnourished Cancer Patients...
CancerDysgeusia4 moreCancer is one of the main causes of death globally, being in many countries the first cause of mortality. One of the main side effects of chemotherapy and/or radiotherapy treatment in cancer patients is the alteration of taste and smell, internationally known as these anomalies Taste Smell Alterations (TSA). These alterations are the result of an altered cellular structure, the presence of TSA is associated with reduced quality of life and poor nutrition, due to dietary changes made by these patients. Synsepalum dulcidicum (dried miracle berry, DMB) is a plant belonging to the Sapotaceae family, made up of around 800 species grouped into around 40 genera. It is an indigenous species to the forest regions of West Africa. Nuts of this specie have been approved as a novel food in accordance with Regulation (EU) 2015/2238 and at the request of the European Commission through the European Food Safety Authority (EFSA) Panel on Nutrition, Novel Foods and Food Allergens. The characteristic component of DMB is miraculin. Miraculin is a glycoprotein whose consumption causes acidic and sour foods, and to a lesser extent bitter, to be perceived as having a sweet taste. In this sense, it is possible that the consumption of DMB before each meal can improve sensory perception after treatment with chemotherapy or radiotherapy.
Astringency and Oral Health
Saliva AlteredTaste1 moreThe perception of astringency is thought to involve the interaction between tannins and salivary proteins. However, the mechanisms underlying this interaction are poorly understood. The tannins' subclass known as type A proanthocyanidins seems to have a positive effect on human health. Despite that, humans show large individual differences in the sensory perception and acceptance of astringent foods such as tea, wine and chocolate suggesting that this variation may have a genetic basis. Salivary proteins play an essential role both in affecting oral taste perception and in maintaining a healthy oral environment. Diverse microorganisms inhabit the oral cavity. The interactions between oral microbiota, host and environmental factors influence microbial homeostasis and ultimately human oral health. Understanding individual differences in salivary proteins, oral microbiome and the mechanisms by which tannins evoke the perception of astringency could provide important insights into the role of these compounds in human nutrition and health.
Impact of a Sensory Rehabilitation Program on Olfactory-gustatory Alterations in Autografted Patients...
Multiple MyelomaOlfactivo-gustatory Disorder1 moreProposition of a sensory rehabilitation program that could reduce the olfactory-gustatory alterations in patients who have been treated with Melphalan for therapeutic intensification with autologous transplantation of hematopoietic stem cells for multiple myeloma or lymphoma, and also improve their life quality, psychological well-being, and nutrition.
Oral and Olfactory Complications of Recovered COVID-19 Patients
Oral ComplicationDysgeusia1 moreThis cohort study aims to investigate the long-standing chemosensory disorders and oral manifestation after recovery of the COVID-19 illness. A correlation between the long-standing symptoms and the COVID-19 severity grade will be very important to understand and clarify the aetiology of these symptoms.
Olfactory and Taste Disturbances in Sjogren's Syndrome
Sjogren's SyndromeSjögren syndrome is an autoimmune disease, responsible for xerostomia and xerophthalmia. Other organs and tissues can be affected: the skin, vaginal and nasal mucous membranes. As well, olfactory disorders have been also described in Sjögren syndrome. Xerostomia often causes significant functional impairment of taste function. Impairment of taste function has been poorly evaluated in Sjögren syndrome like olfactory or (intra-nasal and oral) trigeminal disorders.
Efficacy of Zinc on Concurrent Chemo-radiotherapy Induced Taste Alterations
TasteAlteredTaste changes are common in cancer patients receiving concurrent chemoradiation which become a significant complaint and a cause of distress and morbidity. Loss of gustatory function further advances to malnutrition, weight loss, reduced quality of life, poor compliance and even diminished response to drug therapy. Taste is an essential sensation which serves oral intake of food and enables to prevent the ingestion of potentially harmful and poisonous substances. The sense of taste is crucial for an individual's well-being and psychological health. Taste changes may advance to reduced appetite, dietary insufficiency, food repulsion affecting body weight and anorexia further leading to impaired immunity, decline in health status and malnutrition. As taste impairment is not a life-threatening event therefore it might not be reported by some patients. Hence, this aspect is neglected despite being a common and distressing side-effect of chemoradiation. Due to the location of the cancer and the long-term effects of cancer therapies, patients with oral cavity cancers have a specially high prevalence of chemosensory disorders. Zinc is comparatively non-toxic if taken orally, and rather non-toxic in contrast to other trace metals such as manganese and iron. Zinc is an integral element in both the maintenance and repair of taste buds. It is involved in promoting the diffusion of taste stimuli to taste buds. Salivary zinc has been found in association with Gustin (carbonic anhydrase, CA VI), a zinc-metalloprotein enzyme that may be involved with providing nutrition to the human taste buds. Zinc influences the synthesis of gustin required for the growth, development, maintenance and production of taste buds and regulation of taste function. The hypothesis was: Null hypotheses: There is no difference in the taste acuity between test and control group with the administration of zinc sulfate. Alternative hypotheses: There is a difference in the taste acuity between test and control group with the administration of zinc sulfate. Thus, the present study aimed to observe changes in taste function of oral cancer patients by detection and recognition thresholds before beginning their treatment (before chemoradiation and intervention), at the end of chemoradiation and a month after and to evaluate the preventive effect of zinc sulfate on chemoradiation-induced taste changes. To the best of our knowledge, similar study has not been conducted before in our region.
The Effects of Semaglutide on Taste, Tongue Tissue Transcriptome, Gastric Emptying and Central Neural...
PCOSSemaglutide5 moreThe purpose of the study is to explore the effects of GLP-1 receptor agonist (GLP-1 RA) semaglutide on modulation of taste sensitivity, tongue tissue transcriptome, modulation of neural response in central reward processing regions and gastric emptying rate. In addition, we aim to investigate the associations between semaglutide induced modulation of taste sensitivity, neural responses and gastric emptying with changes in body mass, eating- behavioural pattern, food perception and food intake.
