Taste Perception, Salivary Proteins & the Oral Microbiome

Saliva AlteredTaste1 more

Genetic differences in taste are believed to play an important role in food selection, especially for strong-tasting foods and beverages. The overall goal of this project is to better understand how genes that control food preferences differ among people and whether saliva composition and oral health are related to these differences. This study examines the effects of a daily cranberry extract oral rinse on salivary protein responses and the oral microbiome (as a proxy measure of oral health). The study will be conducted in healthy adults who are presumably at high-risk (non-tasters of PROP; homozygous recessive for tas2R38 gene) or low-risk (super-taster of PROP; homozygous dominant for tas2R38 gene) of oral disease. The specific aims are to determine if the use of cranberry polyphenol extract rinse will: alter the oral microbial profile induce changes in the salivary protein response be associated with changes in taste and flavor perception Participants will be screened for good overall and oral health (see inclusion/exclusion criteria below). Each subject's period of participation will be 2 weeks. Days 1-3 of the study is a run-in period. Subjects rinse with spring water 2-times/day (after brushing their teeth in the morning and evening). During days 4-14, subjects will rinse in a similar manner with a solution of cranberry-derived polyphenol extract (CPE) in spring water. Saliva will be collected from subjects in a brief session (10 min) on Days 3 and Day 14. Saliva samples will be analyzed for salivary proteins and microbial profile analysis. The purpose of this analysis is to measure the relative ratios of beneficial vs. disease-causing microbes in the mouth using 16S RNA sequencing. On each of the testing days, subjects will also evaluate food samples for standard taste and flavor attributes.

Malaysian COVID-19 Anosmia Study (Phase 1) - A Nationwide Multicentre Cross-Sectional Study

SARS-CoV InfectionCOVID-192 more

The Malaysian COVID-19 Anosmia Study is a nationwide multicentre observational study to investigate the prevalence and characteristics of olfactory and gustatory/taste disturbances in COVID-19 infection in Malaysia, and to evaluate the predictive value of screening for these symptoms in COVID-19 infection. This study consists of two phases: the first phase is a cross-sectional study and the second phase is a case-control study. The cross-sectional study is described here (the case-control study is described in a separate ClinicalTrials.gov record).

Breast CancerTaste Disorders3 more

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.

Gustin Gene Polymorphism and 6-n-propylthiouracil (PROP) Taste

Dysgeusia

The investigators evaluate the possible association of PROP taste with gustin gene polymorphism rs2274333 (A/G), salivary zinc ion concentration and BMI. In addition, it has also been evaluated PROP taste sensitivity by recording monophasic potentials from the tongue.

Taste Changes With Bariatric Surgery

TasteAltered

It is commonly believed that a link exists between BMI and taste perception. One group of researchers observed that women who are obese experience reduced taste sensitivity when compared to normal-weight controls. Others have compared taste sensitivity between lean and obese subjects and found no significant differences. The inconsistencies in these studies demonstrate how much variation in taste sensitivity is possible when different factors are applied in research. Throughout several studies, one element remains constant - bariatric surgery causes appetite aversions. These changes in appetite and food preference likely have a large influence on the overall magnitude of post-surgical weight loss. Although many studies have investigated the changes in taste preference after bariatric surgery, few, if any, have focused on changes in sweet taste perception.

Genetics of Bitter and Fat Taste

GeneticsTaste3 more

Obesity is an increasing problem for adults in the UK. Diets high in fat and sugar are the major contributors to weight gain. Individual differences in taste perception are a crucial factor in determining the investigator's choice of foods and an individual's sensitivity to the either bitter or fat taste compounds has been linked to a preference for different foods including sweet and high fat foods. Previous research has not comprehensively explored the effect of both fat and bitter taste sensitivity on dietary intake and obesity status. Therefore, the aim of this study is to explore the associations between genetics, fat and bitter taste sensitivity, food preference, dietary intake and obesity measures in the adult UK population.

Evaluation of Eating Habits and Dysgeusia During Chemotherapy Treatment in Patients Affected by...

Breast CancerDysgeusia2 more

In post-menopause women affected by breast cancer and treated with chemotherapy, overweight and obesity are considered both a risk factors as well as a negative prognostic factors since they increase the risk of early relapse and death. Furthermore, a decrease in weight may also occur during chemotherapy and is associated to a reduced quality of life and survival. Also, the majority of patients under chemotherapy refer dysgeusia, an alteration in taste that can determine food aversion, selection of hypercaloric food or reduced food introduction up to malnutrition. Our aim is to evaluate eating habits changes in patients affected by breast cancer and under chemotherapy treatment and to better understand how this alterations influence the quality of life, anxiety, depression and insomnia of patients as well as overall survival.
