Researchers are studying the effects of hemp-derived minor cannabinoids on symptoms experienced during menopause and perimenopause. This randomized, double-blind, placebo-controlled trial aims to understand how these cannabinoids may influence psychological and physical symptoms in women aged 40 to 60. The study spans three months and includes careful monitoring of emotional, cognitive, and physical health factors associated with menopause. Participants will be randomly assigned to receive either an active hemp-derived cannabinoid product or a placebo, taken three times daily after meals. The study includes a baseline period of four weeks with twice-daily symptom and sleep surveys, weekly cognitive testing via smartphone, and monthly Zoom sessions for detailed cognitive assessments and symptom surveys. Following baseline, two phases of four weeks each will continue with the assigned product, maintaining the same schedule of surveys, cognitive tests, and Zoom assessments. During the study, participants will complete frequent ecological momentary assessments EMA twice daily to report symptoms and side effects, along with weekly cognitive tests on memory, attention, and reaction time. Monthly Zoom sessions will include comprehensive cognitive tests and surveys assessing depression, anxiety, stress, sleep, and memory. Researchers will closely monitor mood, physical symptoms, side effects, and cognitive function throughout the three-month study to evaluate the impact of the cannabinoids on menopause symptoms.

Researchers are evaluating the use of ecological momentary assessments through a smartphone application to study risk and risk factors for tick encounters and tick-borne diseases in the United States. The study focuses on the upper Midwest and Northeast regions, especially Wisconsin, and plans to enroll up to 1000 participants. It aims to understand human behavior related to tick encounters and prevention methods by providing educational messaging within the app. Participants will use the Tick App to record daily logs about their activities, locations, tick encounters, and prevention behaviors over seven days. During part of the year, the apps opening screen will show prevention messages and reminders, with users randomly assigned to receive either a basic tick check reminder or an additional prevention message, such as bathing or showering. This design allows comparison of how different educational messages impact prevention behaviors and tick encounters. Throughout the study, researchers will analyze participants daily logs and compare prevention behaviors and self-reported tick encounters over up to 12 months. The primary outcome is the change in the number of tick prevention behaviors, with a secondary focus on changes in tick encounters. Participants will provide informed consent and complete the daily logs within a year. The study includes safety monitoring of participant adherence and data collection via the app, with no mention of extended follow-up beyond 12 months.

This research aims to explore how regular consumption of specially developed trout, which contain higher levels of omega-3 fatty acids important for brain health, could support cognitive and emotional wellbeing in children and adults. The study addresses the knowledge gap regarding consumer preferences for these fish and how nutrition education strategies might increase fish consumption to benefit brain health and contribute to sustainable aquaculture. Participants will be involved in different groups to assess sensory preferences for three trout strains, effects of repeated exposure and child-centered nutrition messages on eating behaviors, and the impact of nutrition education including meal preparation and exposure to positive messages at home. Interventions include weekly servings of trout, nutrition phrases, puzzle games, and Eat Smart Idahos standard educational classes, with variations across experimental and control groups. Throughout the study, participants will provide feedback on trout liking and intake, and their cognitive and emotional wellbeing will be evaluated at baseline and after 12 weeks. The research includes consumer panels, childcare settings, and home-based interventions, with data collected on changes in liking, intake, cognition scores, and emotion scores. The total participation involves repeated assessments and exposure over up to 12 weeks to monitor brain health and eating behavior changes.
