In this study we are determining whether the hormones associated with the phases of the menstrual cycle (menstruation \& ovulation) influence taste sensitivity to glucose. We hypothesized that women would be more sensitive to oral glucose as assessed by absolute detection threshold during ovulation than when assessed during menstruation. These phases of the cycle are associated with peak plasma estradiol levels and nadir estradiol levels. There is evidence that estrogen can increase the sensitivity of the metabolic signaling pathway of the pancreatic beta-islet cells to stimulate insulin release more readily when glucose is present by increasing sensitivity of the K-ATP channel to ATP. Since the same metabolic signaling pathway is reported to be present in taste tissue, we tested whether peak estrogen levels would enhance taste detection of glucose but not sweeteners that cannot generate ATP, such as sucralose or methyl-D-glucopyranoside (MDG).

Cephalosporin antibiotics are commonly used but can result in allergic reactions and anaphylaxis. There is no clear diagnostic approach for cephalosporin-allergic patients, and guidance for the use of other antibiotics in allergic patients is based on side chain chemical similarity and limited skin testing evidence. This project includes a clinical trial and mechanistic studies to optimize the approach to cephalosporin allergy and advance future diagnostics.

The purpose of this research study is to study the relationship between childhood asthma, allergies, and early-life environmental factors that may cause childhood asthma and allergies. Previous birth cohort studies have found early-life environmental factors such as allergies, pollutants, viruses and bacteria have all contributed to the development of asthma and allergies. Investigators are doing this research because there continues to be a strong need to understand the root causes of asthma and allergies. The CANOE study is an observational cohort study, which means investigators are not asking participants or participant's child to change their medications and investigators will not be giving participants or participant's child a study drug.
Asthma in Children, Allergy
Subcutaneous Immunotherapy (allergy injections) is a potentially disease-modifying therapy that is effective for the treatment of allergic rhinitis/conjunctivitis, allergic asthma and stinging insect hypersensitivity. Pain, which results from the irritation of nearby nerves is a common concern of patients, particularly in children, during or after the injections. This can be a stressful and negative experience for the children. There are various techniques available to minimize pain in general. However, there is a lack of published research on how to use these techniques in children receiving allergy injections. The purpose of this study is to evaluate and compare the efficacy of the standard of care method (Ethyl Chloride/Pain Ease Spray) and three non-pharmacological pain control devices (Buzzy Bee® I, Buzzy Bee II and Shot Blocke®r) in decreasing the perception of pain during subcutaneous allergy injection in a pediatric allergy/immunology clinic setting.

The primary objective of this study is to determine whether allowing ingestion of sub-threshold amounts of peanut in those with a high threshold (tolerate at least 143 mg peanut protein on supervised double-blind, placebo-controlled oral food challenge \[DBPCFC\]) will be associated with attaining even higher thresholds over time in children with high threshold peanut allergy compared to those avoiding peanut. The secondary clinical objectives include assessing the development of sustained unresponsiveness (SU, a surrogate term for tolerance without daily ingestion), effects on quality of life, and safety compared to those avoiding peanut. Additionally, this study will phenotype the allergic response to peanut based on threshold and response to exposure. Mechanistic study objectives will determine the immune and molecular basis of the high threshold endotype, identify predictors of response to exposure, and determine mechanisms and biomarkers of remission.

Atopic dermatitis (AD) is a chronic allergic skin disease with onset in early childhood and increasing prevalence in Westernized countries. Current well newborn guidelines for washing babies with soap were adopted by U.S. hospitals in the 1970s, before the rise in prevalence of allergic disease and AD (also called eczema). Increased transepidermal water-loss (TEWL) in newborn skin at 2 days of life was recently identified as a predictor of AD and allergy development by age 2 years. Risk for AD in babies was also linked to decreased skin colonization with certain skin microflora, such as staphylococcal organisms. Together, these data raise the question of whether newborn skincare guidelines have the potential to modify a baby's risk for allergy development. Our current practice of washing babies with soap may alter TEWL or other natural factors in skin that protect babies from development of AD and allergy. More knowledge is needed about the impact of infant skincare practices on allergy development. The objective of this pilot study is to determine the impact of a baby's first bath on his/her transepidermal water loss (TEWL) and skin microflora. Study procedures will include collection of TEWL measurements and skin swabs for skin microflora analysis pre/post first bath in healthy term newborns at UVA. This data will serve as preliminary data for future studies.

Currently FDA does not accept pharmacokinetic studies to show bioequivalence of locally-acting nasal suspension formulations. However, bioequivalence is defined as the absence of significant differences in pharmacokinetics of therapeutically equivalent drug products compared to the matching originally invented drug formulation. These there-called "generic drugs" are then interchangeable. Drug companies have to show that their generic version has the same active ingredient, the same label, is intended to be used for the same conditions or diseases and works at the same rate in the body. The aim of the study is to determine if pharmacokinetics is sensitive to differences in the particle size distribution of two different nasal suspension formulations of mometasone furoate during charcoal block. The result from this study will aid the FDA in finding methods to ensure that generic products are the same as the trade name drugs.
