Skin Carotenoids Measured by Reflection Spectroscopy Correlate with Dietary Carotenoid Intake in Racially and Ethnically Diverse US Toddlers from Houston, Texas.

Background: Methods to objectively assess fruit and vegetable (FV) intake in young children are needed in order to support rigorous assessments of policies and interventions. Non-invasive skin carotenoid concentration measurements may provide a rapid assessment of toddler carotenoid and carotenoid-rich FV intake. background OBJECTIVE: The aim of this study was to evaluate the relationship between pressure-mediated reflection spectroscopy-measured skin carotenoid scores (SCSs) with proxy-reported carotenoid and FV intake in racially and ethnically diverse, US toddlers.

Upper Gastrointestinal Mucosal Damage and Subsequent Risk of Parkinson Disease.

Importance: The gut-first hypothesis of Parkinson disease (PD) has gained traction, yet potential inciting events triggering Parkinson pathology from gut-related factors remain unclear. While Helicobacter pylori infection is linked to mucosal damage (MD) and PD, it is unknown how upper gastrointestinal MD from any source increases PD risk.

Objective: To evaluate any association between upper endoscopy findings of MD and subsequent clinical PD diagnosis.

The relative validity of nutrition assessment methods for estimating infant carotenoid intake differs by assessment tool, nutrient database, and milk carotenoid adjustment method.

Validated carotenoid assessment methods are needed to study infant carotenoid nutrition. This is a secondary analysis of repeated diet assessments of healthy participants collected at 4- (n = 21), 6- (n = 12), and 8- (n = 9) months of age in Houston, TX between April 2019 and June 2020. Intake was assessed with 3 assessment tools, analyzed with 3 nutrient databases, and underwent 3 adjustments to account for milk composition variability.

Impact of outpatient gastroenterology consult on pharmacotherapy and management of gastrointestinal symptoms in Parkinson's Disease.

Background & Aims: Gastrointestinal (GI) symptoms are common in Parkinson's Disease (PD) patients, and GI dysmotility is thought to induce motor fluctuations, requiring escalation of levodopa therapy. The role of GI consultation in managing such symptoms, however, is unclear. In this study, we investigate the possible association between GI dysmotility symptoms and escalated LEDD therapy, as well as factors associated with GI consultation for PD symptom management.

Reflection Spectroscopy-Assessed Skin Carotenoids Are Sensitive to Change in Carotenoid Intake in a 6-Week Randomized Controlled Feeding Trial in a Racially/Ethnically Diverse Sample.

Background: Reflection spectroscopy, utilized by the Veggie Meter, is a less-expensive, noninvasive method to quantify skin carotenoids and is a valid approximation of fruit and vegetable (FV) intake. However, it is unknown to what degree Veggie Meter-assessed skin carotenoid score change is responsive to changes in carotenoid intake.

Objectives: This study aimed to evaluate Veggie Meter-assessed skin carotenoid score response in a 6-wk randomized controlled trial of a carotenoid-containing juice to determine whether the Veggie Meter can be used to detect nutritionally relevant changes in carotenoid intake; and to compare skin and plasma carotenoid responses with the 6-wk trial.

Isolated sagittal and coronal craniosynostosis associated with TWIST box mutations.

Craniosynostosis, the premature fusion of one or more cranial sutures, affects 1 in 2,500 live births. Isolated single-suture fusion is most prevalent, with sagittal synostosis occurring in 1/5,000 live births. The etiology of isolated (nonsyndromic) single-suture craniosynostosis is largely unknown.
