Randomized Trial Examining the Effect of a 12-wk Exercise Program on Hedonic Eating.

Purpose: This efficacy trial tests the hypothesis that exercise training favorably affects hedonic eating (i.e., overeating, stress-induced overeating, disinhibited eating, eating when tempted), in a sample of women who are overweight or obese.

Anticoagulant Use Among Patients With End-Stage Renal Disease Undergoing Percutaneous Coronary Intervention: An Analysis From the National Cardiovascular Data Registry.

Background: Patients with end-stage renal disease undergoing percutaneous coronary intervention (PCI) have largely been excluded from trials of antithrombotic therapies leaving little data to guide agent choice in this population.

Methods And Results: The National Cardiovascular Data Registry CathPCI Registry was used to identify patients with end-stage renal disease undergoing PCI who received monotherapy with either bivalirudin or unfractionated heparin (UFH) (n=71 675). In hospital bleeding and mortality were compared and adjusted using the CathPCI Registry logistic regression models with generalized estimating equations with UFH as the reference.

Acute deep brain stimulation changes in regional cerebral blood flow in obsessive-compulsive disorder.

OBJECTIVE Deep brain stimulation (DBS) is a reversible, nonlesion-based treatment for patients with intractable obsessive-compulsive disorder (OCD). The first studies on DBS for OCD stimulating the ventral capsule/ventral striatum (VC/VS) yielded encouraging results for this neuroanatomical site's therapeutic efficacy. This investigation was conducted to better understand which regions of the cortico-striatal-thalamic-cortical network were acutely affected by VC/VS DBS for OCD.

Four-Year Physical Activity Levels among Intervention Participants with Type 2 Diabetes.

Unlabelled: Physical activity (PA) has numerous health benefits, particularly for those with diabetes. However, rates of long-term PA participation are often poor.

Purpose: This study examined the effect of an intensive lifestyle intervention (ILI) on objectively assessed PA for a 4-yr period among older adults with type 2 diabetes.

Work It Out Together: Preliminary Efficacy of a Parent and Adolescent DVD and Workbook Intervention on Adolescent Sexual and Substance Use Attitudes and Parenting Behaviors.

The purpose of the current study was to test an interactive DVD and workbook specifically designed for African-American parents and adolescents (ages 13-18), based on an efficacious face-to-face intervention, to address key factors associated with risk. A total of 170 parent-adolescent dyads were enrolled and randomly assigned to receive either the "Work It Out Together" DVD or a General Health Promotion DVD (HP). Parents and adolescents completed measures of HIV knowledge, self-efficacy, and parenting behaviors.

Examination of the Consistency in Affective Response to Acute Exercise in Overweight and Obese Women.

This study examined whether inactive, overweight/obese women experience consistent affective responses to moderate-intensity exercise. Twenty-eight women participated in 3 identical (same treadmill grade and speed within a subject) 30-min exercise sessions. The Feeling Scale (FS), Positive and Negative Affect Schedule and Subjective Exercise Experience Scale were administered pre- and postexercise and FS was also administered every 5 min during exercise.

RAGE siRNA-mediated gene silencing provides cardioprotection against ventricular arrhythmias in acute ischemia and reperfusion.

Expression of receptor for advanced glycation end-products (RAGE) is suggested to play a crucial role in mediating cardiac ischemia/reperfusion (IR) injury, and the blockade of RAGE signaling has been considered as a potential therapeutic strategy for the treatment of IR-induced cardiac damage. In this study, we primarily investigated the effects of RAGE suppression particularly on IR-induced ventricular arrhythmia. To inhibit the IR-induced upregulation of RAGE, siRNA targeting RAGE (siRAGE) was delivered to myocardium by using deoxycholic acid-modified polyethylenimine (PEI-DA) as a non-viral gene carrier.

Weight change in the first 2 months of a lifestyle intervention predicts weight changes 8 years later.

Objective: Examine the relationship between 1- and 2-month weight loss (WL) and 8-year WL among participants enrolled in a lifestyle intervention.

Methods: 2,290 Look AHEAD participants (BMI: 35.65 ± 5.

Examination of whether early weight loss predicts 1-year weight loss among those enrolled in an Internet-based weight loss program.

One-month weight loss (WL) predicts posttreatment WL in face-to-face interventions; however, whether this holds true within Internet programs is unknown. This study examined whether 4-week WL predicts WL following a 12-week Internet program and at 6 and 12 months follow-up. A total of 181 participants (body mass index=33.

Consistency in compensatory eating responses following acute exercise in inactive, overweight and obese women.

It is often assumed that some individuals reliably increase energy intake (EI) post-exercise ('compensators') and some do not ('non-compensators'), leading researchers to examine the characteristics that distinguish these two groups. However, it is unclear whether EI post-exercise is stable over time. The present study examined whether compensatory eating responses to a single exercise bout are consistent within individuals across three pairs of trials.

A common variant in the CLDN7/ELP5 locus predicts adiponectin change with lifestyle intervention and improved fitness in obese individuals with diabetes.

Overweight/obese individuals with Type 2 diabetes have low adiponectin levels, which may improve with lifestyle changes. We investigated whether genetic variants associated with adiponectin levels in genome-wide association studies (GWAS) would also be related with adiponectin changes in response to an intensive lifestyle intervention (ILI), potentially through mechanisms altering the adipose microenvironment via weight loss and/or improved cardiorespiratory fitness. Look AHEAD was a randomized trial comparing the cardiovascular benefits of ILI-induced weight loss and physical activity compared with diabetes support and education among overweight/obese individuals with Type 2 diabetes.

Visuospatial Memory Improvement after Gamma Ventral Capsulotomy in Treatment Refractory Obsessive-Compulsive Disorder Patients.

Gamma ventral capsulotomy (GVC) radiosurgery is intended to minimize side effects while maintaining the efficacy of traditional thermocoagulation techniques for the treatment of refractory obsessive-compulsive disorder (OCD). Neuropsychological outcomes are not clear based on previous studies and, therefore, we investigated the effects of GVC on cognitive and motor performance. A double-blind, randomized controlled trial (RCT) was conducted with 16 refractory OCD patients allocated to active treatment (n=8) and sham (n=8) groups.

Validity of Ratings of Perceived Exertion in Patients with Type 2 Diabetes.

Purpose: To examine whether a subjective measure of moderate-intensity exercise (12-13 on Borg's ratings of perceived exertion scale; RPE) corresponds to the target heart rate for moderate-intensity exercise (40-59% heart rate reserve; %HRR) and to determine the characteristics of those for whom RPE does not appropriately estimate exercise intensity.

Methods: 3582 individuals with type 2 diabetes (age: 58.3±6.

Evaluation of safety and patient subjective efficacy of using radiofrequency and pulsed magnetic fields for the treatment of striae (stretch marks).

Stretch marks are common skin disorders that are dermal scars with associated epidermal atrophy. They are of significant concern or psychological concern to many. This manuscript describes the use of multipolar radiofrequency with pulsed magnetic fields that was successfully used to diminish these lesions in 16 subjects undergoing a series of treatments.

Evaluation of early weight loss thresholds for identifying nonresponders to an intensive lifestyle intervention.

Objective: Weight losses in lifestyle interventions are variable, yet prediction of long-term success is difficult. The utility of using various weight loss thresholds in the first 2 months of treatment for predicting 1-year outcomes was examined.

Methods: Participants included 2327 adults with type 2 diabetes (BMI:35.

Human cardiovascular disease IBC chip-wide association with weight loss and weight regain in the look AHEAD trial.

Background/aims: The present study identified genetic predictors of weight change during behavioral weight loss treatment.

Methods: Participants were 3,899 overweight/obese individuals with type 2 diabetes from Look AHEAD, a randomized controlled trial to determine the effects of intensive lifestyle intervention (ILI), including weight loss and physical activity, relative to diabetes support and education, on cardiovascular outcomes. Analyses focused on associations of single nucleotide polymorphisms (SNPs) on the Illumina CARe iSelect (IBC) chip (minor allele frequency >5%; n = 31,959) with weight change at year 1 and year 4, and weight regain at year 4, among individuals who lost ≥ 3% at year 1.

Genetic modifiers of cardiorespiratory fitness response to lifestyle intervention.

Purpose: Numerous prospective studies indicate that improved cardiorespiratory fitness reduces type 2 diabetes risk and delays disease progression. We hypothesized that genetic variants modify fitness response to an intensive lifestyle intervention (ILI) in the Action for Health in Diabetes (Look AHEAD) randomized clinical trial, aimed to detect whether ILI will reduce cardiovascular events in overweight/obese subjects with type 2 diabetes compared with a standard of care.

Methods: Polymorphisms in established fitness genes and in all loci assayed on the Illumina CARe iSelect chip were examined as predictors of change in MET level, estimated using a treadmill test, in response to a 1-yr intervention in 3899 participants.

FTO predicts weight regain in the Look AHEAD clinical trial.

Background: Genome-wide association studies have provided new insights into the genetic factors that contribute to the development of obesity. We hypothesized that these genetic markers would also predict magnitude of weight loss and weight regain after initial weight loss.

Methods: Established obesity risk alleles available on the Illumina CARe iSelect (IBC) chip were characterized in 3899 overweight or obese participants with type 2 diabetes from the Look AHEAD (Action for Health in Diabetes), a randomized trial to determine the effects of intensive lifestyle intervention (ILI) and diabetes support and education (DSE) on cardiovascular morbidity and mortality.

Calcium measurements from whole heart using Rhod-2.

Calcium recording from whole heart is an important technique to investigate role of calcium in cardiac arrhythmias. Intracellular calcium can be recorded from multiple locations using imaging devices and organic dyes or genetic probe (Tallini et al. PNAS 103(12):4753-4758, 2006) from whole heart.

Physical activity enhancement to a behavioral weight loss program for severely obese individuals: A preliminary investigation.

Severe obesity is characterized by low physical activity (PA) and interventions to enhance PA are needed. Participants (45.0 ± 3.

Immunization with aspartate-β-hydroxylase-loaded dendritic cells produces antitumor effects in a rat model of intrahepatic cholangiocarcinoma.

Unlabelled: Dendritic cells (DCs) capture and process proteins and present peptides on the cell surface in the context of major histocompatibility complex I and II molecules to induce antigen-specific T cell immune responses. The aims of this study were to (1) employ an expanded and purified DC population and load them with aspartate-β-hydroxylase (ASPH), a highly expressed tumor-associated cell surface protein, and (2) to determine if immunization induced antitumor effects in an orthotopic rat model of intrahepatic cholangiocarcinoma. Splenocytes were incubated with ASPH-coated beads and passed through a magnetic field to yield an 80% pure DC OX62+ population.

Effectiveness of lifestyle interventions for individuals with severe obesity and type 2 diabetes: results from the Look AHEAD trial.

Objective: Rates of severe obesity (BMI ≥40 kg/m(2)) are on the rise, and effective treatment options are needed. We examined the effect of an intensive lifestyle intervention (ILI) on weight loss, cardiovascular disease (CVD) risk, and program adherence in participants with type 2 diabetes who were severely obese compared with overweight (BMI 25 to <30 kg/m(2)), class I (BMI 30 to <35 kg/m(2)), and class II (BMI 35 to <40 kg/m(2)) obese participants.

Research Design And Methods: Participants in the Action for Health in Diabetes (Look AHEAD) trial were randomly assigned to ILI or diabetes support and education (DSE).
