Comparison Of A Powdered, Acidified Liquid, And Non-Acidified Liquid Human Milk Fortifier On Clinical Outcomes In Premature Infants., Melissa Thoene, Elizabeth Lyden, Kara Weishaar, Elizabeth Elliott, Ruomei Wu, Katelyn White, Hayley Timm, Ann Anderson-Berry

Journal Articles: Medical Nutrition

We previously compared infant outcomes between a powdered human milk fortifier (P-HMF) vs. acidified liquid HMF (AL-HMF). A non-acidified liquid HMF (NAL-HMF) is now commercially available. The purpose of this study is to compare growth and outcomes of premature infants receiving P-HMF, AL-HMF or NAL-HMF. An Institutional Review Board (IRB) approved retrospective chart review compared infant outcomes (born < 2000 g) who received one of three HMF. Growth, enteral nutrition, laboratory and demographic data were compared. 120 infants were included (P-HMF = 46, AL-HMF = 23, NAL-HMF = 51). AL-HMF infants grew slower in g/day (median 23.66 vs. P-HMF 31.27, NAL-HMF 31.74 (p < 0.05)) and in g/kg/day, median 10.59 vs. 15.37, 14.03 (p < 0.0001). AL-HMF vs. NAL-HMF infants were smaller at 36 weeks gestational age (median 2046 vs. 2404 g, p < 0.05). However AL-HMF infants received more daily calories (p = 0.21) and protein (p < 0.0001), mean 129 cal/kg, 4.2 g protein/kg vs. P-HMF 117 cal/kg, 3.7 g protein/kg , NAL-HMF 120 cal/kg, 4.0 g protein/kg. AL-HMF infants exhibited lower carbon dioxide levels after day of life 14 and 30 (p < 0.0001, p = 0.0038). Three AL-HMF infants (13%) developed necrotizing enterocolitis (NEC) vs. no infants in the remaining groups (p = 0.0056). A NAL-HMF is the most optimal choice for premature human milk-fed infants in a high acuity neonatal intensive care unit (NICU).

Age- And Sex-Related Changes In Fasting Plasma Glucose And Lipoprotein In Cynomolgus Monkeys, Feng Yue, Guodong Zhang, Rongping Tang, Zhouquan Zhang, Liqiong Teng, Zhiming Zhang

Neuroscience Faculty Publications

Background: The age-related dysfunction of glucose and lipid metabolism has a long-standing relationship with cardiovascular and neurodegenerative disease. However, the effects of metabolic dysfunction on men and women are different. Reasons for these sex differences remains unclear. Cynomolgus monkeys have been used, in the past, for the study of human metabolic diseases due to their biologically proximity to humans. Nevertheless, few studies to date have focused on both age- and sex-related differences in glucose and lipid metabolism. The present study was designed to specifically address these questions by using a large cohort of cynomolgus monkeys (N = 1,399) including …

The Synergistic Roles Of Cholecystokinin B And Dopamine D5 Receptors On The Regulation Of Renal Sodium Excretion., Xiaoliang Jiang, Wei Chen, Xing Liu, Zihao Wang, Yunpeng Liu, Robin A Felder, John J Gildea, Pedro A. Jose, Chuan Qin, Zhiwei Yang

Medicine Faculty Publications

Renal dopamine D1-like receptors (D1R and D5R) and the gastrin receptor (CCKBR) are involved in the maintenance of sodium homeostasis. The D1R has been found to interact synergistically with CCKBR in renal proximal tubule (RPT) cells to promote natriuresis and diuresis. D5R, which has a higher affinity for dopamine than D1R, has some constitutive activity. Hence, we sought to investigate the interaction between D5R and CCKBR in the regulation of renal sodium excretion. In present study, we found D5R and CCKBR increase each other's expression in a concentration- and time-dependent manner in the HK-2 cell, the specificity of which was …

BACKGROUND: Interventional trials have used either the Modification of Diet in Renal Disease (MDRD) or chronic kidney disease (CKD)-Epidemiology Collaboration (CKD-EPI) equation for determination of estimated glomerular filtration rate (eGFR) to define whether participants have stages 3-5 CKD. The equation used to calculate eGFR may influence the number and characteristics of participants designated as having CKD.

METHODS: We examined the classification of CKD at baseline using both equations in the Systolic Blood Pressure Intervention Trial (SPRINT). eGFR was calculated at baseline using fasting serum creatinine values from a central laboratory.

RESULTS: Among 9,308 participants with baseline CKD classification using the …

The Effect Of Dietary Fruits & Vegetable Consumption And Physical Activity On Obesity In African American Adolescent Females., Tanisha Brooks

Walden Dissertations and Doctoral Studies

Obesity is epidemic among Black adolescent females, and adolescent obesity often leads to adult obesity. Previous research suggests that there may be an interaction between physical activity and dietary fruit and vegetable intake on body mass index (BMI) in obese adolescent females in general, but it was unclear whether the same pattern is evident in Black adolescent females, who, on average, tend to have low levels of physical activity and fruit and vegetable intake. Bandura's social learning theory implies the possibility that adolescent females might model their behaviors on the behavior of others in their high school years, including physical …
