The purpose of this study is to investigate the energy needs and nutritional status of adolescent girls in Abia State, Nigeria
The goal of this observational study is to compare the effects of air pollution exposure and nutrition between neighborhoods with high and low social vulnerability scores. The main questions this study aims to answer are: * Does living in a neighborhood with high or low vulnerability influence the response of the heart, lungs, and immune system to air pollution. * Does nutritional status alter the association between air pollution exposure and changes in the heart, lungs, and immune system. Participants (age 25-70 years) that live in neighborhoods ranked high or low on the Social Vulnerability Index (SVI) will take part in 3 visits. Each visit involves the following: * Measurements of heart activity, lung function, and blood to measure changes that may be caused by air pollution. * Questionnaires about the types of food eaten and activities that may modify exposure to air pollution. * Estimation of air pollution exposure using a study iPhone. Participants will carry a study iPhone with them for 24 hours at each visit. The study iPhone runs an application (app) that estimates the amount of air pollution each participant is exposed to. * Wearing silicone wristbands for a week before each study visit. Silicone wristbands absorb air pollutants and are later measured see the types and amounts of chemicals participants are exposed to.
Conduct a prospective, longitudinal study to evaluate nutritional status in adults with phenylketonuria (PKU) before and during treatment with pegvaliase (Palynziq™).
Conduct a cross-sectional analysis of the nutritional status of individuals with PKU treated with pegvaliase for one or more years or who have followed an unrestricted diet for 6 or more months while on pegvaliase treatment. We will evaluate laboratory markers of nutritional status, including markers of protein and micronutrient nutriture. In addition, a three-day food record and food frequency questionnaire will be obtained to assess protein intake and overall diet quality.
Carbon-12 and carbon-13 are naturally-occurring isotopes that are found in exhaled breath. Investigators have proved that the 13CO2/12CO2 breath delta value (BDV) changes in subjects who were in negative energy balance then fed a positive energy balance meal. Measuring one liter of exhaled breath daily may be a more convenient way to measure negative or positive energy balance in patients receiving intravenous nutrition.
Individuals with IBD are at risk for nutrient deficiencies. This prospective, non-randomized, open-label study will assess the effect of a nutrition support product on nutritional status in adults with IBD. Up to ten adults with ulcerative colitis or Crohn's disease will be enrolled in the study and asked to take the product for 12 weeks. The primary measures of the study are several blood markers of nutritional status.
The study is designed to evaluate how the composition of a participant's body, diagnosed with a brain tumor (glioblastoma multiforme) as determined by bioelectrical impedance analysis can predict the progression and outcomes of disease.
The purpose of this study is to compare the accuracy of a new consumer nutrition screening tool to an established and validated nutrition screening tool currently completed by healthcare practitioners.
This study examines the effects of an infant formula containing increased calories, as compared to commercial formulas, when given during the first 6 months of life. It will examine effects on growth, disease progress, immune system, and quality of life of infected infants. HIV disease in infants often leads to nutritional deficiencies. Providing increased nutrition early in their lives may help the quality of life of children who contract HIV from their mothers.

This study evaluates the effect of a six-month fruit and vegetable voucher program on satisfaction, dietary quality, and health outcomes among pediatric and young adult kidney transplant recipients experiencing food insecurity.
African Americans have higher rates of diabetes, obesity, heart disease, and high blood pressure. In addition, middle-aged non-Hispanic Black adults develop multiple chronic conditions (MCCs) at an earlier age, which share most of the same risk factors, including poor diet and physical inactivity. The major goal of the proposed project is to develop a culturally tailored intervention focused on improving awareness, knowledge, diet quality, and physical activity in a cohort of AA adults with MCCs.
It is a 12-week study. The participants will follow three different diets, and during each diet period, and the participants will wear our device, and blood samples will be collected.
The purpose of this study is to identify survival free of bronchopulmonary dysplasia (BPD), fatty acid profiles, and early biochemical measures for oxidative stress comparing mixed oil lipid emulsion (MOLE) vs soybean oil-based lipid emulsion (SOLE) and to establish whether MOLE or SOLE is more effective in minimizing pulmonary outcomes, neonatal morbidities, long-term morbidity and mortality, and improving discharge growth and Bayley Scales of Infant Development Fourth Edition (BSID-IV) neurodevelopmental assessment at two years

A total of 200 participants will be randomly assigned to receive healthy lifestyle education in addition to routine care, or routine care alone. Participants will be asked to participate in the following activities: * Blood draws to test hemoglobin A1c and lipids * Surveys about diet, physical activity, sleep, and tobacco use * Gaples Nutritional Education Modules (if applicable)
Early nutrition critically influences growth, neurodevelopment and morbidity among infants born of very low birth weight (VLBW), but current one-size-fits-all feeding regimes do not optimally support these vulnerable infants. There is increasing interest in "precision nutrition" approaches, but it is unclear which Human Milk (HM) components require personalized adjustment of doses. Previous efforts have focused on macronutrients, but HM also contains essential micronutrients as well as non-nutrient bioactive components that shape the gut microbiome. Further, it is unclear if or how parental factors (e.g. body mass index, diet) and infant factors (e.g. genetics, gut microbiota, sex, acuity) influence relationships between early nutrition and growth, neurodevelopment and morbidity. Understanding these complex relationships is paramount to developing effective personalized HM feeding strategies for VLBW infants. This is the overarching goal of the proposed Optimizing Nutrition and Milk (Opti-NuM) Project. The Opti-NuM Project brings together two established research platforms with complementary expertise and resources: 1) the MaxiMoM Program\* with its clinically embedded translational neonatal feeding trial network in Toronto (Dr. Deborah O'Connor, Dr. Sharon Unger) and 2) the International Milk Composition (IMiC) Consortium, a world-renowned multidisciplinary network of HM researchers and data scientists collaborating to understand how the myriad of HM components contribute "as a whole" to infant growth and development, using systems biology and machine learning approaches. Members of the IMiC Corsortium that will work with on this study are located at the University of Manitoba (Dr. Meghan Azad), University of California (Dr. Lars Bode) and Stanford (Dr. Nima Aghaeepour).
The goal of this study is to find ways to help families with children who have limited incomes get better access to healthy and culturally appropriate foods. The study will test a program called "medically tailored grocery box delivery," which sends boxes of healthy groceries to families based on their specific health needs. The study aims to answer: 1. Can this grocery delivery program improve families' access to healthy foods and support better eating habits? 2. Will families use the groceries provided, and how effective is the program overall? To answer these questions, researchers will: * Work with the community to design the grocery program and make sure the foods meet families' cultural preferences. * Test how well the program can be carried out in real-world settings. * Compare how the program affects families' access to healthy food, eating habits, and use of the grocery boxes.
The survey will help investigators learn everything about how people view and respond to trauma from a holistic perspective through body (nutrition), mind (mental health rejuvenation and renewal), and spirit (faith-based) lens. Researchers aim to evaluate if such practices will be effective in helping participants with significant life challenges due to trauma, negative life events, or extremely stressful events will recover from these types of lifestyles. The responses will be used to shape the integrative protocols that the investigators develop for professionals involved with trauma clients. This can help increase recovery rates and lead to productive lives.
The overarching purpose of this study is to assess whether patients will use the app throughout treatment on a regular basis, as the ultimate goal is to provide an educational platform that can impact patient behaviors and understanding towards health.
The goal of this experiment is to examine the impact of policy rationale on public support for prison nutrition standards. The main question this experiment aims to answer is: Does the rationale provided for a policy to improve prison nutrition standards impact public support for such a policy? Additionally, this experiment aims to answer: To what extent are participant demographic characteristics correlated with public support for prison nutrition standards?
The goal of this clinical trial is to learn if an urban gardening nutrition education program can have positive health effects on food insecure college students. The main question it aims to answer is to determine whether an 8-week urban-gardening nutrition intervention can improve fruit and vegetable intake, nutrition knowledge, Body Mass Index (BMI) and body fat percentage in college students with food insecurity. Participants will: Fill out a questionnaire regarding demographics, food insecurity, fruit and vegetable intake, nutrition knowledge, self-efficacy and health beliefs. Allow researchers to measure height, weight and body fat percentage Participate in a 1-hour education cooking or gardening session once a week for 8 weeks Receive text message reminders for meeting dates
This is a Phase 3, randomized, double-blind, controlled, adaptive, 2-arm, multicenter study to demonstrate the efficacy and safety of DefenCath in adult participants receiving home Total Parenteral Nutrition (TPN) via Central Venous Catheter (CVC) compared with heparin.
Many children and adults receiving medical treatments have higher costs, which can make it harder for them to afford groceries. When someone can't afford enough food, and they do not receive proper nutrition it can make treatment more difficult. By doing this study investigators hope to learn more about whether addressing food insecurity by giving patients bags of food in clinic can help improve nutrition, reduce costs, and improve transplant and cellular therapy outcomes.
This clinical trial aims to assess the effect of nutrition and exercise on muscle and adiposity in adults with Philadelphia Chromosome (Ph) Negative B-ALL undergoing inpatient induction therapy. Participants will take part in 2 different interventions: * Nutrition Intervention * Physical Exercise Intervention All subjects will be provided with a wearable electronic activity monitor (FitBit®) to assist in recording activity levels in minutes of activity.
The goal of this study is to understand the best practices for implementing produce prescriptions among adults with overweight or obesity experiencing nutrition insecurity. Enrolled participants will receive an 8-week intervention aimed at increasing nutrition knowledge, self-efficacy for healthy eating, and barriers to healthy food access. Participants will be randomly assigned to one of two produce prescription implementation strategies: Program 1: Participants will receive weekly produce vouchers that are redeemable at a local vendor. Program 2. Participants will receive fresh produce delivered directly to the participant's home. These boxes will be tailored based on household size, cooking and preparation preferences, and produce the participant prefers to receive. Researchers will compare engagement in and adherence to the intervention and the patterns of difference in 8-week changes in fruit and vegetable consumption and weight.
Compared to non-Veterans, Veterans demonstrate an increased risk for obesity and multimorbidity. Thus, interventions to improve overall health are warranted in this population. Healthy diets that include fruits and vegetables are linked to a reduced risk of chronic disease including mobility disability, and are associated with higher muscle mass, strength and physical performance potentially slowing further disability progression later in life. The investigators will determine if a three-month virtual group nutrition intervention paired with produce delivery and virtual teaching kitchen cooking demonstrations tailored for older Veterans with impaired mobility will improve diet, health-related quality of life and muscle strength.
The goal of this interventional study is to learn if having 15 minutes of surgery related nutrition education changes the food choices participants make during the time right before and after a spine surgery in participants who have a surgery with Dr. John Edwards. The main questions it aims to answer are: * Does nutrition education at a participant's preoperative appointment help them choose healthier foods and drinks that help their recovery from surgery? * Does choosing to drink some extra nutrients before and after surgery help participants feel better and make it easier to have other foods and liquids after surgery? Researchers will compare participants getting extra education with those in a control group who have normal instructions from the clinic to see if extra education makes a difference in people's food choices. Researchers will also look at how well participants do with the extra nutrition they get before and after surgery, and if choosing to include it changes with the extra education. Participants will: * Complete 2 surveys (PROMIS global and food frequency) at both their preoperative and postoperative appointments * Complete one survey 2 days after their surgery asking about how well they did with liquids and solid foods in the 24 hours after surgery * Choose whether or not they decide to have a drink with extra nutrients before and after surgery, and let the researchers know what they chose.
The purpose of this Study is to assist in implementing a practical, easy-to-adopt lifestyle intervention that optimizes patient outcomes and minimizes pancreatic ductal adenocarcinoma (PDAC) risk.
The purpose of this study is to define human milk (HM) as an ecosystem which investigators will then combine into temporal models of milk dynamics to accurately describe HM chronobiology. This study addresses 4 crucial public health gaps: 1) how breast milk changes over time and over the day, 2) how milk dynamics are related to infant sleep patterns, 3) how milk dynamics are related to infant microbiome dynamics, and 4) how all these relationships differ between infants fed directly at-the-breast vs pumped milk. These fundamental insights have been unknown until now, so that families who feed pumped breast milk are completely underserved. These results are critical to optimizing infant feeding and health outcomes for all infants receiving breast milk.
