Body Composition And Cardiometabolic Health Across The Menopause Transition, Kara L. Marlatt, Dori R. Pitynski-Miller, Kathleen M. Gavin, Kerrie L. Moreau, Edward L. Melanson, Nanette Santoro, Wendy M. Kohrt

Clinical Research Faculty Publications

Every year, 2 million women reach menopause in the United States, and they may spend 40% or more of their life in a postmenopausal state. In the years immediately preceding menopause—known as the menopause transition (or perimenopause)—changes in hormones and body composition increase a woman’s overall cardiometabolic risk. In this narrative review, we summarize the changes in weight, body composition, and body fat distribution, as well as the changes in energy intake, energy expenditure, and other cardiometabolic risk factors (lipid profile, glucose metabolism, sleep health, and vascular function), that occur during the menopause transition. We also discuss the benefits of …

Soule, Thomas Eissenberg, Michael S. Amato, Amanda L. Graham, Corby K. Martin, Christoph Höchsmann, Bernard F. Fuemmeler

Clinical Research Faculty Publications

Background: E-cigarette device and liquid characteristics, such as electrical power output and liquid nicotine concentration, determine the rate at which nicotine is emitted from the e-cigarette (i.e., nicotine flux), and thus are likely to influence user nicotine dependence. We hypothesize that nicotine flux would be associated with the E-cigarette Dependence Scale (EDS) among pod-based and disposable e-cigarette products. Methods: Data were obtained from online panel participants between 18 and 65 years of age, who had indicated that they were either former or current e-cigarette users and resided within the United States (N = 1036). To be included in these analyses, …

Deriving A Tree Growth Model From Any Existing Stand Growth Model, Quang V. Cao Jan 2022

Deriving A Tree Growth Model From Any Existing Stand Growth Model, Quang V. Cao

Faculty Publications

In this study, a new method was developed to derive a tree survival and diameter growth model from any existing stand-level model, without the need for individual-tree growth data. Predictions from the derived tree model are constrained to match the number of trees and the basal area per hectare as outputted by the stand model. The tree models derived from three different stand models were evaluated against a tree model, in both unadjusted and disaggregated forms. For the same stand-level model, the derived tree model outperformed its counterpart, the disaggregated tree model. Furthermore, except for one stand model with poor …

Predicting Future Diameter Distributions Given Current Stand Attributes, Quang V. Cao Jan 2022

Predicting Future Diameter Distributions Given Current Stand Attributes, Quang V. Cao

Faculty Publications

This study discussed four methods to project a diameter distribution from age A1 to age A2. Method 1 recovers parameters of the distribution at age A2 from stand attributes at that age. Method 2 uses a stand-level model to grow the quadratic mean diameter, and then recovers the distribution parameters from that prediction. Method 3 grows the diameter distribution by assuming tree-level survival and diameter growth functions. Method 4 first converts the diameter distribution at age A1 into a list of individual trees before growing these trees to age A2. In a numerical example employing the Weibull distribution, methods 3 …

Deriving Tree Growth Models From Stand Models Based On The Selfthinning Rule Of Chinese Fir Plantations, Xiongqing Zhang, Quang V. Cao, Yancheng Qu, Jianguo Zhang

Faculty Publications

Self-thinning due to density-dependent mortality usually occurs during the forest development. To improve predictions of such processes during forest successions under climate change, reliable stand-level models are needed. In this study, we developed an integrated system of tree-and stand-level models by deriving tree diameter and survival models from stand growth and survival models based on climate-sensitive self-thinning rule of Chinese fir plantations in subtropical China. The resulting integrated system, having a unified mathematical structure, should provide consistent estimates at both tree and stand levels. Predictions were reasonable at both stand and tree levels. Because stand-level values aggregated from the tree …

The Vegetarian/Flexitarian Diets, Derek Miketinas, Catherine M. Champagne Jan 2022

The Vegetarian/Flexitarian Diets, Derek Miketinas, Catherine M. Champagne

Population and Public Health Science Faculty Publications

Vegetarian diets are popular for their documented health benefits, ethical considerations, cost-effectiveness, and other perceived benefits. These diets can be nutritionally superior to the typical Western diet for reducing chronic disease risk including cardiovascular disease, obesity, certain cancers, and type 2 diabetes. Although the health benefits of vegetarian diets are well documented, they are comparable to other diets that do not necessarily restrict animal products, such as the Dietary Approach to Stop Hypertension (DASH) and Mediterranean diets. Restricting entire food groups can present nutritional concerns, including potentially inadequate intakes of some micronutrients; however, the clinical manifestations of such deficiencies are …

The Mediterranean Diet: A Healthy Dietary Plan, George A. Bray, Catherine M. Champagne Jan 2022

The Mediterranean Diet: A Healthy Dietary Plan, George A. Bray, Catherine M. Champagne

Population and Public Health Science Faculty Publications

The concept of a Mediterranean diet can be attributed to Ancel Keys. His insights began the study of this dietary pattern and its many variations. Components of the Mediterranean diet have been described and compared to other high-quality diets. The health benefits from the diet have been examined in four separate categories. Central adiposity was significantly less in individuals adhering to a Mediterranean diet than those with poorer adherence scores to a Mediterranean diet. Substituting different types of monounsaturated or polyunsaturated fat for saturated fat, red meat, or carbohydrate significantly reduced body weight. The risk of developing diabetes and the …

Rates of suicide in the US Army continue to rise, and by some accounts exceed the general population. This increase has renewed efforts to identify protective factors that may inform novel suicide prevention strategies. Previous research has demonstrated that a sense of purpose in life and perceived cohesion with military peers are related to a reduction in the severity of suicidal ideation (SI). Additionally, research in military samples supports decreased SI in Soldiers who endorse that their leaders convey a sense of purpose and meaning in their shared mission. However, no work has investigated whether these leadership styles relate to …

Effects Of Maternal Diabetes And Diet On Gene Expression In The Murine Placenta, Claudia Kappen, Claudia Kruger, J. Michael Salbaum Jan 2022

Effects Of Maternal Diabetes And Diet On Gene Expression In The Murine Placenta, Claudia Kappen, Claudia Kruger, J. Michael Salbaum

Division of Basic Science Faculty Publications

Adverse exposures during pregnancy have been shown to contribute to susceptibility for chronic diseases in offspring. Maternal diabetes during pregnancy is associated with higher risk of pregnancy complications, structural birth defects, and cardiometabolic health impairments later in life. We showed previously in a mouse model that the placenta is smaller in diabetic pregnancies, with reduced size of the junctional zone and labyrinth. In addition, cell migration is impaired, resulting in ectopic accumulation of spongiotrophoblasts within the labyrinth. The present study had the goal to identify the mechanisms underlying the growth defects and trophoblast migration abnormalities. Based upon gene expression assays …

Insulin Resistance Persists Despite A Metabolically Healthy Obesity Phenotype, Kristin K. Hoddy, Christopher L. Axelrod, Jacob T. Mey, Adithya Hari, Robbie A. Beyl, Jourdan B. Blair, Wagner S. Dantas, John P. Kirwan

Division of Basic Science Faculty Publications

Objective: Metabolically healthy obesity (MHO) is often defined as the absence of metabolic syndrome in the presence of obesity. However, phenotypic features of MHO are unclear. Insulin sensitivity in MHO was cross-sectionally compared with metabolically unhealthy obesity (MUO) and a reference group of young healthy participants without obesity. Methods: Sedentary adults (n = 96) undergoing anthropometric, blood chemistries, maximal aerobic capacity, and euglycemic-hyperinsulinemic clamp measurements were classified by BMI (< 25 and ≥30 kg/m2). MUO was defined as having obesity with metabolic syndrome (≥2 additional risk factors). Data were analyzed using a linear mixed models approach. Results: Body weight was similar between MHO and MUO. Body fat (percentage) and high-density lipoprotein cholesterol were higher (p < 0.001), and systolic blood pressure, triglycerides, glucose, and insulin were lower in MHO versus MUO (p < 0.03, all). The MHO group also had lower high-density lipoprotein cholesterol and higher low-density lipoprotein cholesterol, diastolic blood pressure, and insulin compared with the reference. Both the MHO and MUO groups displayed impaired insulin sensitivity compared with the reference control (p < 0.001). Conclusions: Participants with MHO had distinct clinical measures related to hypertension, lipid metabolism, and glycemic control compared with a healthy reference group. Peripheral insulin resistance in obesity independent of metabolic status portends increased risk for type 2 diabetes in the MHO patient population.

Increased Alveolar Epithelial Traf6 Via Autophagy-Dependent Trim37 Degradation Mediates Particulate Matter-Induced Lung Metastasis, Jiajun Liu, Shumin Li, Xuefeng Fei, Xi Nan, Yingying Shen, Huiqing Xiu, Stephania A. Cormier, Chaojie Lu, Chuqi Guo, Shibo Wang, Zhijian Cai, Pingli Wang

Division of Basic Science Faculty Publications

Epidemiological and clinical studies have shown that exposure to particulate matter (PM) is associated with an increased incidence of lung cancer and metastasis. However, the underlying mechanism remains unclear. Here, we demonstrated the central role of PM-induced neutrophil recruitment in promoting lung cancer metastasis. We found that reactive oxygen species (ROS)-mediated alveolar epithelial macroautophagy/autophagy was essential for initiating neutrophil chemotaxis and pre-metastatic niche formation in the lungs in response to PM exposure. During PM-induced autophagy, the E3 ubiquitin ligase TRIM37 was degraded and protected TRAF6 from proteasomal degradation in lung epithelial cells, which promoted the NFKB-dependent production of chemokines to …

Nonlinear Conditional Time-Varying Granger Causality Of Task Fmri Via Deep Stacking Networks And Adaptive Convolutional Kernels, Kai Cheng Chuang, Sreekrishna Ramakrishnapillai, Lydia Bazzano, Owen Carmichael

Clinical Research Faculty Publications

Time-varying Granger causality refers to patterns of causal relationships that vary over time between brain functional time series at distinct source and target regions. It provides rich information about the spatiotemporal structure of brain activity that underlies behavior. Current methods for this problem fail to quantify nonlinear relationships in source-target relationships, and require ad hoc setting of relationship time lags. This paper proposes deep stacking networks (DSNs), with adaptive convolutional kernels (ACKs) as component parts, to address these challenges. The DSNs use convolutional neural networks to estimate nonlinear source-target relationships, ACKs allow these relationships to vary over time, and time …

We address the problem of constructing matrix-valued interval observers for estimating state transition matrices for time-varying systems. We provide less conservative estimators than those in recent literature. We cover continuous-and discrete-time linear systems, under Metzler or nonnegativity conditions on the coefficient matrices. We show how to satisfy our Metzler conditions after simple changes of coordinates. We illustrate our method using a feedback stabilized underwater marine robotic dynamics with unknown control gains.
