Item A health research agenda guided by migratory and seasonal farmworkers and the providers who serve them(Patient-Centered Outcomes Research Institute (PCORI), 2018-11) Holmes, Cheryl; Levy, Michelle; Mariscal, E. SusanaThis document shares the results of an almost two-year process to create a health research agenda specific to migratory and seasonal farmworkers. The purpose was to better understand what health outcomes are important to farmworkers in two Midwestern states and identify research and information gaps. A key strategy in accomplishing this work was not only to engage farmworkers in addition to providers, researchers and various other administrators but to do so in an active, direct and frequent manner, thus highlighting and elevating their voices and perspectives. This document is organized in that spirit.Item The Academic Model Providing Access To Healthcare (AMPATH) in Kenya(Global Livestock CRSP, UC Davis, 2008-11) Nyandiko, Winstone; Siika, Abraham; Ernst, Judith A.; Ettyang, Grace; Neumann, Charlotte; Yiannoutsos, ConstantinIn sub-Saharan Africa, an estimated 28 million people are living with the human immunodeficiency virus (HIV) and acquired immunodeficiency syndrome (AIDS). In 2001, Moi University in Eldoret, Kenya joined with Kenya’s second national referral hospital, Moi Teaching and Referral Hospital (MTRH) and Indiana University (IU) to establish the Academic Model Providing Access To Healthcare (AMPATH). AMPATH’s missions were to (1) provide high-quality patient care; (2) educate patients and health care providers; and (3) establish a laboratory for clinical research in HIV/AIDS (http://medicine.iupui.edu/kenya/hiv.aids.html). Leveraging the power of an academic medical partnership, AMPATH has quickly become one of the largest and most comprehensive HIV/AIDS control systems in sub-Saharan Africa, providing a comprehensive system of care that has been described as a model of sustainable development (Tobias, 2006). Delivery of services occurs in the public sector through hospitals and health centers run by Kenya’s Ministry of Health. AMPATH currently implements prevention activities that touch the lives of millions of persons in a wide geographic area. The research arm of AMPATH, created to facilitate and manage the international research agenda being generated by Kenyan and US faculty, includes the Global Livestock CRSP’s HIV Nutrition Project (HNP), “Increasing Animal Source Foods in Diets of HIV-infected Kenyan Women and Their Children,” which is a collaborative initiative between AMPATH and faculty from Moi University, Indiana University and the University of California, Los Angeles.Item ACTUAL AND PRESCRIBED ENERGY AND PROTEIN INTAKES FOR VERY LOW BIRTH WEIGHT INFANTS: AN OBSERVATIONAL STUDY(2012-10-11) Abel, Deborah Marie; Rickard, Karyl A.; Brady, Mary Sue; Engle, William A.; Ingram, David A.; Poindexter, Brenda B.Objectives: To determine (1) whether prescribed and delivered energy and protein intakes during the first two weeks of life met Ziegler’s estimated requirements for Very Low Birth Weight (VLBW) infants, (2) if actual energy during the first week of life correlated with time to regain birth weight and reach full enteral nutrition (EN) defined as 100 kcal/kg/day, (3) if growth velocity from time to reach full EN to 36 weeks’ postmenstrual age (PMA) met Ziegler’s estimated fetal growth velocity (16 g/kg/day), and (4) growth outcomes at 36 weeks’ PMA. Study design: Observational study of feeding, early nutrition and early growth of 40 VLBW infants ≤ 30 weeks GA at birth in three newborn intensive care units NICUs. Results: During the first week of life, the percentages of prescribed and delivered energy (69% [65 kcal/kg/day]) and protein (89% [3.1 g/kg/day]) were significantly less than theoretical estimated requirements. Delivered intakes were 15% less than prescribed because of numerous interruptions in delivery and medical complications. During the second week, the delivered intakes of energy (90% [86 kcal/kg/day]) and protein (102% [3.5 g/kg/day]) improved although the differences between prescribed and delivered were consistently 15%. Energy but not protein intake during the first week was significantly related to time to reach full EN. Neither energy nor protein intake significantly correlated with days to return to birth weight. The average growth velocity from the age that full EN was attained to 36 weeks’ PMA (15 g/kg/day) was significantly less than the theoretical estimated fetal growth velocity (16 g/kg/day) (p<0.03). A difference of 1 g/kg/day represents a total deficit of 42 - 54 grams over the course of a month. At 36 weeks’ PMA, 53% of the VLBW infants had extrauterine growth restriction, or EUGR (<10th percentile) on the Fenton growth grid and 34% had EUGR on the Lubchenco growth grid. Conclusions: The delivered nutrient intakes were consistently less than 15% of the prescribed intakes. Growth velocity between the age when full EN was achieved and 36 weeks’ PMA was 6.7% lower than Ziegler’s estimate. One-third to one-half of the infants have EUGR at 36 weeks’ PMA.Item Acute High Dietary Phosphorus Following Low-Phosphorus Diet Acclimation Does Not Enhance Intestinal Fractional Phosphorus Absorption in Nephrectomized Male Rats(Wiley, 2022-11-16) Burstad, Kendal M.; Cladis, Dennis P.; Vorland, Colby J.; Wastney, Meryl E.; Biruete, Annabel; Dominguez, James M., II; O’Neill, Kalisha D.; Chen, Neal X.; Moe, Sharon M.; Hill Gallant, Kathleen M.; Medicine, School of MedicineDietary phosphorus restriction and phosphorus binders are commonly prescribed for patients with chronic kidney disease (CKD). However, occurrences of non-adherence to these interventions are common. As low-phosphorus (LP) diets have been consistently experimentally shown in vitro to increase intestinal phosphorus absorption efficiency, a bout of non-adherence to diet or binders may cause an unintended consequence of enhanced intestinal phosphorus absorption. Thus, we aimed to determine the effect of a single bout of high-phosphorus (HP) intake after acclimation to a LP diet. Male Sprague Dawley rats with 5/6 nephrectomy (n = 36) or sham operation (n = 36) were block-randomized to 1 of 3 diets: LP (0.1% P w/w), HP (1.2%), or LP followed by acute HP (LPHP 0.1% then 1.2%). Phosphorus absorption tests were conducted using 33P radioisotope administrated by oral gavage or intravenously (iv). Although the overall two-way ANCOVA model for intestinal fractional phosphorus absorption was non-significant, exploratory comparisons showed intestinal fractional phosphorus absorption efficiency tended to be higher in rats in the LP compared with HP or LPHP groups. Rats in the HP or LPHP groups had higher plasma phosphorus compared with rats in the LP group, but the LPHP group was not different from the HP group. Gene expression of the major intestinal phosphate transporter, NaPi-2b, was lower in the jejunum of rats in the LPHP group compared with rats in the HP group but not different in the duodenum. These results demonstrate that an acute HP load after acclimation to a LP diet does not lead to enhanced intestinal fractional phosphorus absorption efficiency in 5/6 nephrectomized male rats. These data provide evidence against the notion that dietary phosphorus restriction or binder use adversely increases absorption efficiency after a single instance of dietary or binder non-adherence. However, other adverse consequences of fluctuating dietary phosphorus intake cannot be ruled out.Item Addressing Food Insecurity: Lessons Learned from Co-Locating a Food Pantry with a Federally Qualified Health Center(Ubiquity Press, 2022-09-30) Reinoso, Deanna; Haut, Dawn; Claffey, Stephen; Hahn Keiner, Kathy; Chavez, Alejandra; Nace, Nicole; Carter, Amy; Pediatrics, School of MedicineIntroduction: Social determinants of health, such as food insecurity, contribute to chronic health conditions, decreased quality of life, and health disparities. Increasingly, healthcare systems seek to address social determinants of health by integrating medical and social care. Description: Eskenazi Health Center Pecar is a Federally Qualified Health Center providing comprehensive primary care to vulnerable patients in Indianapolis, IN, USA. This health center, in coalition with community partners, established and continually developed an integrated food pantry model to address food insecurity, improve nutrition education, and support patient access to healthy food. Discussion: Food insecurity and poor nutrition are common in primary care and contribute to the incidence and outcomes of chronic conditions such as obesity, hypertension, and diabetes. Long-term management of food assistance and nutrition programs requires substantial resources, partnerships, and leadership. We describe lessons learned in food pantry partnership, funding, logistics, and sustainability in a collaborative food access model integrated into healthcare. These lessons learned can be utilized by other health systems to scale up and accelerate strategies to better address food security and nutrition education. This paper articulates best practices for integrating a food pantry model within primary care with the goal of long-term sustainability and direct impact on patient health outcomes.Item Addressing unmet needs for people with cancer cachexia: recommendations from a multistakeholder workshop(Wiley, 2022-04) Garcia, Jose M.; Dunne, Richard F.; Santiago, Kristen; Martin, Lisa; Birnbaum, Morris J.; Crawford, Jeffrey; Hendifar, Andrew E.; Kochanczyk, Martin; Moravek, Cassadie; Piccinin, Doris; Picozzi, Vincent; Roeland, Eric J.; Selig, Wendy K.D.; Zimmers, Teresa A.; Surgery, School of MedicineItem Advances in pediatric acute kidney injury pharmacology and nutrition: a report from the 26th Acute Disease Quality Initiative (ADQI) consensus conference(Springer, 2024) Wong Vega, Molly; Starr, Michelle C.; Brophy, Patrick D.; Devarajan, Prasad; Soranno, Danielle E.; Akcan‑Arikan, Ayse; Basu, Rajit; Goldstein, Stuart L.; Charlton, Jennifer R.; Barreto, Erin; Pediatrics, School of MedicineBackground: In the past decade, there have been substantial advances in our understanding of pediatric AKI. Despite this progress, large gaps remain in our understanding of pharmacology and nutritional therapy in pediatric AKI. Methods: During the 26th Acute Disease Quality Initiative (ADQI) Consensus Conference, a multidisciplinary group of experts reviewed the evidence and used a modified Delphi process to achieve consensus on recommendations for gaps and advances in care for pharmacologic and nutritional management of pediatric AKI. The current evidence as well as gaps and opportunities were discussed, and recommendations were summarized. Results: Two consensus statements were developed. (1) High-value, kidney-eliminated medications should be selected for a detailed characterization of their pharmacokinetics, pharmacodynamics, and pharmaco-"omics" in sick children across the developmental continuum. This will allow for the optimization of real-time modeling with the goal of improving patient care. Nephrotoxin stewardship will be identified as an organizational priority and supported with necessary resources and infrastructure. (2) Patient-centered outcomes (functional status, quality of life, and optimal growth and development) must drive targeted nutritional interventions to optimize short- and long-term nutrition. Measures of acute and chronic changes of anthropometrics, body composition, physical function, and metabolic control should be incorporated into nutritional assessments. Conclusions: Neonates and children have unique metabolic and growth parameters compared to adult patients. Strategic investments in multidisciplinary translational research efforts are required to fill the knowledge gaps in nutritional requirements and pharmacological best practices for children with or at risk for AKI.Item Association of Tryptophan and NAD+ Metabolites with Brain and Skeletal Muscle Function in Critical Care Patients and Survivors(2024-07) Yates, Brandon Alston; Coggan, Andrew; Khan, Babar; Kroenke, Kurt; Liu, Ziyue; Newman, JohnBackground: Patients who survive Intensive Care Unit (ICU) acquired delirium will likely experience new or worsened physical, mental, and/or cognitive impairments (termed Post-Intensive Care Syndrome (PICS)). Although advances in critical care treatments have reduced mortality rates among older adult ICU survivors, roughly 67% suffer PICS. The most vulnerable to long-term physical and cognitive impairments are older adults or those who exhibit accelerated aging because of pre-existing physical frailty or cognitive frailty. Yet, identification of at-risk patients during admittance is likely difficult because of the 1) homogeneity in the clinical presentation of patients with pre-existing age-related physical frailty and critical illness compared to those suffering from only critical illness and 2) many patients arrive severely debilitated making administration of physical function or other volitional assessments difficult. Therefore, it is essential that new biomarkers to guide early diagnosis, prognosis, and disease monitoring are identified. To this point, tryptophan derivatives, particularly kynurenines and nicotinamide family (e.g., NAD+), have been shown to mediate the relationship between chronic inflammation and physical impairment or signal accelerated aging, respectively. However, it remains unknown if similar associations exist in ICU patients and the prognostic utility of elevated neurotoxic tryptophan metabolites relative to neuroprotective tryptophan metabolites to predict adverse health outcomes while in the ICU. Methods: A secondary analysis of pooled data from three randomized control trials was used to investigate the following aims. To address Aims 1 and 2, blood samples from patients with ICU acquired delirium were analyzed for kynurenine and salvage pathway metabolites. To address Aim 3, blood samples from patients who survived an ICU stay, experienced ICU delirium, and completed both objective and subjective physical function assessments within in month of ICU discharge and before the COVID-19 pandemic. Results: Delirium duration was significantly (p< 0.05) associated with elevated circulating kynurenine and lower NAD+. Delirium severity was significantly associated with elevated circulating lower NAD+ but not kynurenine. Post-ICU physical function performance was significantly associated with elevated circulating kynurenine but not NAD+. Conclusion: Elevated concentration of frailty biomarkers are associated with delirium severity and duration in the ICU and post-ICU physical function.Item Associations of Habitual Dietary Intake With Fecal Short-Chain Fatty Acids and Bowel Functions in Irritable Bowel Syndrome(Wolters Kluwer, 2022) Calderon, Gerardo; Patel, Chirag; Camilleri, Michael; James-Stevenson, Toyia; Bohm, Matthew; Siwiec, Robert; Rogers, Nicholas; Wo, John; Lockett, Carolyn; Gupta, Anita; Xu, Huiping; Shin, Andrea; Medicine, School of MedicineBackground goals: Diet may contribute to symptoms of irritable bowel syndrome (IBS) and luminal production of putative IBS biomarkers including short-chain fatty acids (SCFAs). Study aims were to to assess relationships of habitual fiber or starch intake with fecal SCFAs in patients with IBS and healthy volunteers (HVs). Study: In 18 HVs and 30 patients with IBS (13 constipation-predominant [IBS-C] and 17 diarrhea-predominant [IBS-D]), habitual diet using a food frequency questionnaire; bowel functions using a validated bowel diary; and fecal SCFAs by HPLC-mass spectrometry were assessed. Associations of fiber and starch with SCFAs were analyzed using Spearman (rs) and Pearson (R) correlations. Relationships between other dietary endpoints, SCFAs, and bowel functions were explored. Results: Habitual fiber or starch intakes were not significantly correlated with SCFAs or bowel functions in all participants or HVs nor with SCFAs in IBS. Starch was negatively correlated (R=-0.53; P=0.04) with complete evacuation in IBS-D. Fiber (rs=0.65; P=0.02) and starch (rs=0.56; P=0.05) were correlated with ease of passage in IBS-C. Stool form, frequency, and ease of passage were positively correlated with total SCFAs (all P<0.05), acetate (all P<0.01), propionate (all P<0.05), and butyrate (form P=0.01; ease of passage P=0.05) among all participants, but not in IBS. Complete evacuation was negatively correlated with propionate (R=-0.34; P=0.04) in all participants. Total (P=0.04) and individual SCFAs (all P<0.05) were positively correlated with stool form in HVs. Conclusions: Habitual fiber and starch intake does not influence fecal SCFAs but may influence bowel functions in IBS. Fecal SCFAs correlate with bowel functions among all participants including HVs.Item Cartoon of "Uncle Doc" eating an apple.(Indiana State Board of Health, 1934-03)[Text within image] A vitamine in an apple is worth two in the spinach.
