Harris, Callie Hebert, Neil M. Johannsen, Steven B. Heymsfield, Frank L. Greenway, Arny A. Ferrando, Jennifer C. Rood, Stefan M. Pasiakos

Clinical Research Faculty Publications

Physical performance decrements observed during multi-stressor military operations may be attributed, in part, to cellular membrane dysfunction, which is quantifiable using phase angle (PhA) derived from bioelectrical impedance analysis (BIA). Positive relationships between PhA and performance have been previously reported in cross-sectional studies and following longitudinal exercise training programs, but whether changes in PhA are indicative of acute decrements in performance during military operations is unknown. Data from the Optimizing Performance for Soldiers II study, a clinical trial examining the effects of exogenous testosterone administration on body composition and performance during military stress, was used to evaluate changes in PhA …

Factors Influencing Consumers’ Willingness-To-Try Seafood Byproducts, Silvia Murillo, Ryan Ardoin, Witoon Prinyawiwatkul

Faculty Publications

With increasing global demand for seafood, seafood byproducts (SB) utilization can contribute to a more sustainable food supply chain through waste-to-value food product development. However, consumer perceptions of SB (e.g., fish skin and bones) are underexplored. Therefore, this study aims to evaluate some factors influencing consumers’ willingness-to-try seafood byproducts. An online survey was conducted in the USA regarding intervention of SB informational cues with N = 904 adult seafood consumers internationally. The proportion of consumers willing to try SB increased significantly (McNemar’s test, α = 0.05) from 47% to 68% after SB safety and health claims had been presented in …

Unhealthy Herds And The Predator–Spreader: Understanding When Predation Increases Disease Incidence And Prevalence, Robert L. Richards, Bret D. Elderd, Meghan A. Duffy Mar 2023

Unhealthy Herds And The Predator–Spreader: Understanding When Predation Increases Disease Incidence And Prevalence, Robert L. Richards, Bret D. Elderd, Meghan A. Duffy

Faculty Publications

Disease ecologists now recognize the limitation behind examining host–parasite interactions in isolation: community members—especially predators—dramatically affect host–parasite dynamics. Although the initial paradigm was that predation should reduce disease in prey populations (“healthy herds hypothesis”), researchers have realized that predators sometimes increase disease in their prey. These “predator–spreaders” are now recognized as critical to disease dynamics, but empirical research on the topic remains fragmented. In a narrow sense, a “predator–spreader” would be defined as a predator that mechanically spreads parasites via feeding. However, predators affect their prey and, subsequently, disease transmission in many other ways such as altering prey population structure, …

Using The Exploration, Preparation, Implementation, And Sustainment (Epis) Framework To Advance The Science And Practice Of Healthy Food Retail, Bailey Houghtaling, Sarah Misyak, Elena Serrano, Rachael D. Dombrowski, Denise Holston, Chelsea R. Singleton, Samantha M. Harden

Faculty Publications

Although healthy food retail strategies are widely used, there appears to be a limited understanding of the processes and determinants for successful adoption, implementation, and sustainment. To fill this gap, we recommend the Exploration, Preparation, Implementation, and Sustainment (EPIS) framework to be used to advance the science and practice of healthy food retail. In this perspective, we: (1) introduce EPIS and describe why it was chosen as a recommended implementation science framework for healthy food retail, (2) highlight healthy food retail evidence supporting EPIS, and (3) discuss research and practice needs moving forward.

Population and Public Health Science Faculty Publications

Objective: Trends in obesity prevalence and trends in control of cardiometabolic risk factors among National Health and Nutrition Examination Survey participants with diabetes from 1999 through 2020 were analyzed. Methods: Adults who were 20 years or older and who reported having received a diagnosis of diabetes from a physician were included. Results: The prevalence of overall obesity, obesity class II, and obesity class III increased from 46.9%, 14.1%, and 10.3% in 1999 to 2002 to 58.1%, 16.6%, and 14.8% in 2015 to 2020, respectively. The prevalence of participants who achieved glycemic control (HbA1c < 7%) increased from 42.5% in 1999 to 2002 to 51.8% in 2007 to 2010, then decreased to 48.0% in 2015 to 2020. The prevalence of participants who achieved blood pressure control (< 140/90 mmHg) or achieved non-high-density lipoprotein cholesterol control (< 130 mg/dL) increased throughout the study periods. The prevalence of participants who met all three risk factor goals increased from 8.3% in 1999 to 2002 to 21.2% in 2011 to 2014 and then decreased to 18.5 in 2015 to 2020. Participants with obesity showed worsening glycemic control and lipid control than participants with normal weight. Conclusions: There were increasing trends in prevalence of obesity, blood pressure control, and lipid control from 1999 to 2002 to 2015 to 2020. Participants with obesity showed worsening glycemic control and lipid control than normal-weight participants.

Asprosin Promotes Feeding Through Sk Channel-Dependent Activation Of Agrp Neurons, Bing Feng, Hesong Liu, Ila Mishra, Clemens Duerrschmid, Peiyu Gao, Pingwen Xu, Chunmei Wang, Yanlin He Feb 2023

Asprosin Promotes Feeding Through Sk Channel-Dependent Activation Of Agrp Neurons, Bing Feng, Hesong Liu, Ila Mishra, Clemens Duerrschmid, Peiyu Gao, Pingwen Xu, Chunmei Wang, Yanlin He

Division of Basic Science Faculty Publications

Asprosin, a recently identified adipokine, activates agouti-related peptide (AgRP) neurons in the arcuate nucleus of the hypothalamus (ARH) via binding to protein tyrosine phosphatase receptor δ (Ptprd) to increase food intake. However, the intracellular mechanisms responsible for asprosin/Ptprd-mediated activation of AgRPARH neurons remain unknown. Here, we demonstrate that the small-conductance calcium-activated potassium (SK) channel is required for the stimulatory effects of asprosin/Ptprd on AgRPARH neurons. Specifically, we found that deficiency or elevation of circulating asprosin increased or decreased the SK current in AgRPARH neurons, respectively. AgRPARH-specific deletion of SK3 (an SK channel subtype highly expressed in AgRPARH neurons) blocked asprosin-induced …

Analysis And Technical Optimization Of Processing Condition For Better Quality Of Robusta Coffee Production, Usman Ahmad, Khalimatus Sa’Diyah, Sathivel Subramaniam Feb 2023

Analysis And Technical Optimization Of Processing Condition For Better Quality Of Robusta Coffee Production, Usman Ahmad, Khalimatus Sa’Diyah, Sathivel Subramaniam

Faculty Publications

The wet processing of robusta coffee starts with harvesting coffee cherries, followed by sorting the cherries, pulping, fermentation, washing, drying, hard skin hulling, bean sorting, and packaging. Soaking fruit before pulping is an alternative for coffee farmers to delay the pulping process if time does not al-low it. The fermentation process aims to remove mucus that is firmly attached to the hard skin. The addition of L. casei bacteria can accelerate the process but affect the final taste. This study aimed to optimize the duration of soaking and fermentation processes for obtaining coffee beans with a minimum number of unpeeled …

Effects Of Neighborhood Disadvantage And Peer Deviance On Conduct Problems: Interactions With Age Of Onset, Courtney Marie Goetz Feb 2023

Effects Of Neighborhood Disadvantage And Peer Deviance On Conduct Problems: Interactions With Age Of Onset, Courtney Marie Goetz

LSU Master's Theses

Youth with conduct problems (CP) generally fall into two developmental classifications, child-onset and adolescent-onset, which exhibit different causal processes and life course trajectories. Research suggests that child-onset CP is more likely to be related to individual predispositions, while adolescent-onset CP is more associated with social factors, such as peer delinquency. Living in impoverished and disorganized neighborhoods increases the risk for associating with deviant peers. Thus, the current study tested the hypothesis that neighborhood factors would be more strongly associated with adolescent-onset CP than child-onset CP, which would be explained by a greater association with deviant peers. Linear and negative binomial …

Mushroom by-products are economical and eco-friendly raw materials with bioactive and functional characteristics that allow for potential uses as food ingredients. However, mushroom upcycling has yet to be fully exploited, despite the many opportunities that mushrooms may offer. The mushroom protein by-product (MPBP) resulting from mushroom protein production was characterized (chemical composition, physicochemical attributes, and functional properties) and incorporated into plant-based batter formulations to prepare four experimental groups with different ratios (w/w, %) of wheat flour (W) to MPBP (100 W, 75 W/25 MPBP, 25 W/75 MPBP, and 100 MPBP). Subsequently, the batter was used for frying batter-coated shrimp, which …

Heart rate variability (HRV) provides a simple method to evaluate autonomic function in health and disease. A reduction in HRV may indicate autonomic dysfunction and is strongly associated with aspects of cardiometabolic disease, including hyperglycemia. Reduced nitric oxide (NO) bioavailability is also implicated in the development of cardiometabolic disease and autonomic dysfunction. Watermelons are natural sources of L-arginine and L-citrulline, substrates used for NO synthesis. Watermelon consumption can improve NO bioavailability. We conducted a randomized, double-blind, placebo-controlled crossover trial to test the effects of 2 weeks of daily watermelon juice (WMJ) supplementation on HRV in response to an oral glucose …

Investigating The Potential Role Of Termites As Pathogen Vectors In The Decline Of Ironwood Trees (Casuarina Equisetifolia) In Guam, Garima Setia Jan 2023

Investigating The Potential Role Of Termites As Pathogen Vectors In The Decline Of Ironwood Trees (Casuarina Equisetifolia) In Guam, Garima Setia

LSU Master's Theses

Termites have been found associated with the decline of Casuarina equisetifolia (ironwood), an important agro-forestry species in Guam. While the ironwood tree decline (IWTD) was first reported in 2002, its association with termites as well as with bacteria Ralstonia solanacearum and Klebsiella species (K. oxytoca and K. variicola) was determined in 2010 and 2012 respectively. In 2019, the termite species attacking the ironwood trees were identified as Nasutitermes takasagoensis, Coptotermes gestroi, and Microcerotermes crassus. However, the role of termites in IWTD is not known. Since termites are repositories of bacteria and consume wood, termite foragers might …
