Pre-Training Muscle Characteristics Of Subjects Who Are Obese Determine How Well Exercise Training Will Improve Their Insulin Responsiveness, Charles A. Stuart, Michelle L. Lee, Mark A. South, Mary E. A. Howell, Brian M. Cartwright, Michael W. Ramsey, Michael H. Stone

Mark A. South

Pre-training muscle characteristics of subjects who are obese determine how well exercise training will improve their insulin responsiveness. J Strength Cond Res 31(3): 798–808, 2017—Only half of prediabetic subjects who are obese who underwent exercise training without weight loss increased their insulin responsiveness. We hypothesized that those who improved their insulin responsiveness might have pretraining characteristics favoring a positive response to exercise training. Thirty nondiabetic subjects who were obese volunteered for 8 weeks of either strength training or endurance training. During training, subjects increased their caloric intake to prevent weight loss. Insulin responsiveness by euglycemic clamps and muscle fiber composition, …

Cellular Senescence And Their Role In Liver Metabolism In Health And Disease: Overview And Future Directions, Matthew Schade, Jacqueline A. Sanabria, Rodrigo Aguilar, Milad Modarresi, Brad Gillon, Zach Hunter, Jacqueline Fannin, Amrita Mallick, Henri Brunengraber, Juan Sanabria

Juan R. Sanabria

Chronic liver disease has globally risen mainly due to a prevalent Hepatitis C Virus (HCV) infection rate and an epidemic of obesity. It is estimated by the year 2030, 2.2 billion people around the world will be overweight and 1.1 billion people will be obese. Diabetes and obesity are the main risk factors for the development of the metabolic syndrome and in the liver of Non-Alcoholic Fatty Liver Disease (NAFLD) which could progress to NASH related cirrhosis and liver malignancy. At present there is not effective therapy for NASH besides loss of weight and exercise. Furthermore, optimal management of HCC …

Divergent Relationship Of Circulating Ctrp3 Levels Between Obesity And Gender: A Cross-Sectional Study, Roy Marshall Wagner, Kamesh Sivagnanam, W. Andrew Clark, Jonathan M. Peterson

W. Andrew Clark

C1q TNF Related Protein 3 (CTRP3) is a novel adipose tissue derived secreted factor, or adipokine, which has been linked to a number of beneficial biological effects on metabolism, inflammation, and survival signaling in a variety of tissues. However, very little is known about CTRP3 in regards to human health. The purpose of this project was to examine circulating CTRP3 levels in a clinical population, patients with symptoms requiring heart catheterization in order to identify the presence of obstructive coronary artery disease (CAD). It was hypothesized that serum CTRP3 levels would be decreased in the presence of CAD.

The Effects Of Obesity On Outcomes In Trauma Injury: Overview Of The Current Literature, Milad Modarresi, Brad Gillon, Javad Najjar Mojarrab, Rodrigo Aguilar, Zackary Dylan Hunter, Matthew Steven Schade, Jackie Sanabria, Rebecca Klug, Seth Adkins, Juan R. Sanabria

Juan R. Sanabria

Obesity has reached epidemic proportions and is now considered a chronic disease by the National Institute of Health (NIH) in the West. Its impact on trauma outcomes is of particular interest with several studies presenting conflicting information. The present overview suggests a strong association between obesity and injury severity, hospital length of stay (LOS), intensive care unit (ICU) admission, pattern of injury, rate of complications and mortality. The nature of the observations may relate to an underlying physiological state of the obese patient and its associated comorbidities with a constant heightened inflammatory state aggravated by the second hit on an …

Mobile Health Interventions For Adult Obesity In The United States: Analysis Of Effectiveness And Efficacy, David P. Paul Iii, Keerthi Gochipathala, Alberto Coustasse, Bezawit Wodajo, Niharika Bhardwaj

Alberto Coustasse, DrPH, MD, MBA, MPH

The Unites States continues to struggle with the negative health effects associated with increasing population obesity, a problem which has been historically difficult, if not impossible, to solve. Mobile health applications represent a potential partial solution to this problem. We examine the existing literature on the effects of mobile health applications on body weight, waist circumference, BMI, and lifestyle, examining both physical findings as well as adherence, satisfaction and cost effectiveness. The use of mobile for weight reduction looks promising, but evidence is mixed, which is not surprising given the rapidly evolving nature of the mobile application field.

Tolerability Of Induction Chemotherapy Dosing Practices In Acute Myeloid Leukemia Patients, Kaylene M. Peric, David J. Reeves

David Reeves

For patients with high body surface areas (BSA), differing chemotherapy dosing strategies have been utilized in attempts to reduce toxicity. In a retrospective evaluation, we compared the effects of chemotherapy dosing in acute myeloid leukemia patients with high BSA (>2 m2) who received capped doses (n = 12) to those who received uncapped doses (n = 24), and to patients with BSA ≤ 2 m2 (n = 42). There were no statistically significant differences among groups (BSA ≤ 2 m2, BSA > 2 m2 capped, and BSA > 2 m2 uncapped) in the incidences of febrile neutropenia (85.7, 66.7, and 75.0%, …

Presentation of case

A 65 year old male, who had undergone laparoscopic gastric banding two months prior for morbid obesity, presented to the clinic complaining of abdominal pain and night time fever of 4 days duration. Urgent gastroscopy revealed eroded gastric band which was removed laparoscopically.

Discussion

M. chelonae are not uncommon in Queensland. Although the mode of acquisition of infection remains unclear, it is suspected that human disease results from environmental exposure to dirty soil and water. The patient lives in rural …

Should Primary Care Physicians Address Sleep To Improve Weight Loss In Obese Patients? A Clin-Iq, Kjersti E. Knox

Kjersti Knox, MD

Obesity is a commonly encountered problem in the primary care setting. Simultaneously, sleep is seen to hold an increasingly important role in many components of health and wellness. A review of the literature was performed to determine if improving sleep positively impacts weight loss in obese adults. The evidence reviewed suggests that improving patients’ sleep may initially improve patient weight loss; however, current studies do not show a sustained statistically significant impact. Until higher powered and higher quality studies are completed, there are no clear evidence-based guidelines for primary care physicians to follow regarding sleep and obesity.

Proyecto Mama: A Lifestyle Intervention In Overweight And Obese Hispanic Women: A Randomised Controlled Trial--Study Protocol, Lisa Chasan-Taber, Bess H. Marcus, Milagros C. Rosal, Katherine L. Tucker, Sheri J. Hartman, Penelope S. Pekow, Edward J. Stanek Iii, Barry Braun, Caren G. Solomon, Joanne Manson, Sarah L. Goff, Glenn Markenson

Sarah L. Goff MD

BACKGROUND: The proportion of women entering pregnancy overweight or obese has been rising and, in turn, is associated with adverse maternal and fetal outcomes. Gestational weight gain (GWG) exceeding Institute of Medicine (IOM) guidelines further increases health risks and has been independently associated with postpartum weight retention. Hispanic women are disproportionately affected by overweight and obesity, but have had limited access to interventions that promote healthy lifestyles due to cultural, socioeconomic, and language barriers. Therefore, the overall goal of this randomized controlled trial is to test the efficacy of a culturally and linguistically modified, individually-tailored lifestyle intervention to reduce excess …

A Randomized, Double-Blind, Placebo-Controlled Trial Of Adjunctive Metformin Therapy In Overweight/Obese Youth With Type 1 Diabetes, Benjamin U. Nwosu, Louise Maranda, Karen Cullen, Lisa Greenman, Jody Fleshman, Nancy Mcshea, Bruce A. Barton, Mary M. Lee

Benjamin U. Nwosu

CONTEXT: Insulin resistance has been proposed as one of the causes of poor glycemic control in overweight/obese youth with type 1 diabetes (T1D). However, the role of adjunctive metformin, an insulin sensitizer, on glycemic control in these patients is unclear.

OBJECTIVE: To compare the effect of metformin vs. placebo on hemoglobin A1c (HbA1c), total daily dose (TDD) of insulin, and other parameters in overweight/obese youth with T1D.

HYPOTHESIS: Adjunctive metformin therapy will improve glycemic control in overweight/obese youth with T1D.

DESIGN, SETTING, AND PARTICIPANTS: A 9-mo randomized, double-blind, placebo controlled trial of metformin and placebo in 28 subjects (13m/15f) of …

Cd36 And Na/K-Atpase- Α 1 Form A Proinflammatory Signaling Loop In Kidney, David Kennedy, Yiliang Chen, Wenxin Huang, Jamie Viterna, Jiang Liu, Kristen Westfall, Jian Tian, David Bartlett, W.H. Tang, Zijian Xie, Joseph Shapiro, Roy Silverstein

Jiang Liu

Proatherogenic, hyperlipidemic states demonstrate increases in circulating ligands for scavenger receptor CD36 (eg, oxidized low-density lipoprotein [oxLDL]) and the Na/K-ATPase (eg, cardiotonic steroids). These factors increase inflammation, oxidative stress, and progression of chronic kidney disease. We hypothesized that diet-induced obesity and hyperlipidemia potentiate a CD36/Na/K-ATPase–dependent inflammatory paracrine loop between proximal tubule cells (PTCs) and their associated macrophages and thereby facilitate development of chronic inflammation and tubulointerstitial fibrosis. ApoE^-/- and apoE^-/-/cd36^-/- mice were fed a high-fat diet for ≤32 weeks and examined for physiologic and histologic changes in renal function. Compared with apoE^-/-, apoE^{-/- …}

Prieurianin Causes Weight Loss In Diet-Induced Obese Mice And Inhibits Adipogenesis In Cultured Preadipocytes, Ahmed Kablan, Rudel A. Saunders, Maria Szkudlarek-Mikho, Andrew J.B. Chin, Raul M. Bosio, Kazuyuki Fujii, Joseph I. Shapiro M.D., Khew-Voon Chin

Joseph I Shapiro MD

The global increase in the incidence of obesity has emerged as one of the most serious public health risks in recent years. Despite the enormity of the obesity pandemic, there are currently only two FDA-approved therapies for its treatment and these drugs exhibit modest effi cacy and have limiting side effects. Prieurianin is a plant limonoid product that deters feeding in insect larvae. We investigated in this study the effects of prieurianin on weight loss and adipogenesis. Our results showed that prieurianin causes weight loss by reducing energy intake in obese mice on highcalorie diet. We also found that prieurianin …

Benjamin U. Nwosu

Background. It is unknown whether the coexistence of type 1 diabetes (T1D) and celiac disease (CD) increases the risk for vitamin D deficiency.

Aims. To determine the vitamin D status and the risk for vitamin D deficiency in prepubertal children with both T1D and CD compared to controls, TID, and CD.

Subjects and Methods. Characteristics of 62 prepubertal children of age 2–13 y with either CD + T1D (� = 22, 9.9 ± 3.1 y), CD only (� = 18, 8.9 ± 3.3 y), or T1D only (� = 22, 10.1 ± 2.8 y) were compared to 49 controls of …

A Potential Role For Adjunctive Vitamin D Therapy In The Management Of Weight Gain And Metabolic Side Effects Of Second-Generation Antipsychotics, Benjamin U. Nwosu, Bruce Meltzer, Louise Maranda, Carol A. Ciccarelli, Daniel Reynolds, Laura A. Curtis, Jean A. King, Jean A. Frazier, Mary M. Lee

Mary M. Lee

Second-generation antipsychotic (SGA) medications introduced about 20 years ago are increasingly used to treat psychiatric illnesses in children and adolescents. There has been a five-fold increase in the use of these medications in U.S. children and adolescents in the past decade. However, there has also been a parallel rise in the incidence of side effects associated with these medications, such as obesity, dyslipidemia, insulin resistance, and diabetes mellitus. Despite the severity of these complications and their financial impact on the national healthcare budget, there is neither a clear understanding of the mechanisms contributing to these side effects nor the best …

Treatment Of Adult Obesity With Bariatric Surgery, Robin Schroeder, Jordan Garrison, Mark Johnson

Robin S. Schroeder MD

Bariatric surgery procedures, including laparoscopic adjustable gastric banding, laparoscopic sleeve gastrectomy, and Roux-en-Y gastric bypass, result in an average weight loss of 50 percent of excess body weight. Remission of diabetes mellitus occurs in approximately 80 percent of patients after Roux-en-Y gastric bypass. Other obesity-related comorbidities are greatly reduced, and health-related quality of life improves. The Obesity Surgery Mortality Risk Score can help identify patients with increased mortality risk from bariatric surgery. Complications and adverse effects are lowest with laparoscopic surgery, and vary by procedure and presurgical risk. The Roux-en-Y procedure carries an increased risk of malabsorption sequelae, which can …

The Relationship Between Subnormal Peak-Stimulated Growth Hormone Levels And Auxological Characteristics In Obese Children, Jefferson Barrett, Louise S. Maranda, Benjamin U. Nwosu

Benjamin U. Nwosu

Context: The hypothesis that obese children are overdiagnosed with growth hormone deficiency (GHD) has not been adequately investigated in the context of adiposity-related differences in auxology.

Aim: To investigate the differences in auxological parameters between short, prepubertal, obese children, and normal-weight peers who underwent growth hormone stimulation testing (GHST).

Hypothesis: Over-weight/obese children with GHD [peak growth hormone (GH) < 10 μg/L] will have higher values for growth velocity (GV) standard deviation score (SDS), bone age minus chronological age (BA − CA), and child height SDS minus mid-parental height (MPTH) SDS when compared to normal-weight GHD peers.

Subjects and Methods: A retrospective review of anthropometric and provocative GHST data of 67 prepubertal, GH-naïve children of age 10.21 ± 2.56 years (male n = 45, age 10.8 ± 2.60 years; female n = 22, age 8.94 ± 2.10). Inclusion …

Risk Of Early & Late Obstetric Complications In Women With Ivf- Conceived Pregnancies And Polycystic Ovary Syndrome (Pcos), N. A. Bagegni, J. Blaine, Bradley J. Van Voorhis, Anuja Dokras

Bradley J Van Voorhis

There is conflicting evidence on the association between PCOS and early and late obstetric complications. It is unclear if the reported risks are independent of BMI, preexisting hypertension and diabetes. We performed a retrospective chart review to examine the risk of early and late obstetrical complications after IVF in women with PCOS (n=130) compared to controls (n=130). The miscarriage rate was 17.7% in PCOS women and 15.4% in controls. PCOS was not associated with miscarriage independent of age and BMI. The prevalence of gestational DM (GDM) was similar in both groups (12% PCOS versus 11% controls). BMI was independently associated …

The Relationship Between Adiposity And Stature In Prepubertal Children With Celiac Disease, Benjamin U. Nwosu, Rachel I. Snook, Louise S. Maranda

Benjamin U. Nwosu

Background and Aim: The pathogenesis of short stature in celiac disease (CD) is unknown. Obese children are generally taller than their non-obese peers; however, the role of adiposity on stature in CD is unclear. Our aim was to determine the association between adiposity and stature in CD.

Subjects and methods: We compared the anthropometric characteristics of prepubertal children of ages 3-12 years, with biopsy-proven CD (n=40) and who were not on gluten-free diet, to same aged, prepubertal non-CD children (n=50). Body mass index (BMI) was calculated using the formula weight/height2. Sex-adjusted midparental target height (MPTH) standard deviation score (SDS) was …

Obesity And Insulin Resistance But Not Hyperandrogenism Mediates Vascular Dysfunction In Women With Polycystic Ovary Syndrome., Anuja Dokras, Dinesh Jagasia, Michelle Maifeld, Christine Sinkey, Bradley Van Voorhis, William Haynes

Bradley J Van Voorhis

OBJECTIVE: Polycystic ovary syndrome (PCOS) is associated with biochemical evidence of early atherosclerosis; however, data regarding vascular function are controversial. We hypothesized that resistance vessel function (mediated by the endothelium or smooth muscle) would be impaired in women with PCOS and aimed to determine the contribution of hyperandrogenism, obesity, or insulin resistance to vascular dysfunction.

DESIGN: Prospective study.

SETTING: University practice.

PATIENT(S): Women with PCOS (n = 24) and age/weight-matched controls (n = 22).

INTERVENTION(S): Vascular function was assessed by measuring forearm vasodilatation in response to both endothelium-dependent (acetylcholine/bradykinin) and endothelium-independent dilators (nitroprusside/verapamil).

MAIN OUTCOME MEASURE(S): Resistance vessel function.

RESULT(S): …
