Abstract

Fibrosis is a common pathological feature of chronic disease. Deletion of the NF-κB subunit c-Rel limits fibrosis in multiple organs, although the mechanistic nature of this protection is unresolved. Using cell-specific gene-targeting manipulations in mice undergoing liver damage, we elucidate a critical role for c-Rel in controlling metabolic changes required for inflammatory and fibrogenic activities of hepatocytes and macrophages and identify Pfkfb3 as the key downstream metabolic mediator of this response. Independent deletions of Rel in hepatocytes or macrophages suppressed liver fibrosis induced by carbon tetrachloride, while combined deletion had an additive anti-fibrogenic effect. In transforming growth factor-β1-induced hepatocytes, c-Rel regulates expression of a pro-fibrogenic secretome comprising inflammatory molecules and connective tissue growth factor, the latter promoting collagen secretion from HMs. Macrophages lacking c-Rel fail to polarize to M1 or M2 states, explaining reduced fibrosis in RelΔLysM mice. Pharmacological inhibition of c-Rel attenuated multi-organ fibrosis in both murine and human fibrosis. In conclusion, activation of c-Rel/Pfkfb3 in damaged tissue instigates a paracrine signalling network among epithelial, myeloid and mesenchymal cells to stimulate fibrogenesis. Targeting the c-Rel-Pfkfb3 axis has potential for therapeutic applications in fibrotic disease. ispartof: NATURE METABOLISM vol:2 issue:11 ispartof: location:Germany status: published

Abstract

Objective Maintaining weight loss is a major challenge in obesity treatment. Individuals often indicate that waning motivation prompts cessation of effective weight management behaviors. Therefore, a novel weight loss maintenance program that specifically targets motivational factors was evaluated. Design Overweight women (N=338; 19% African American) with urinary incontinence were randomized to lifestyle obesity treatment or control and followed for 18 months. All participants in lifestyle (N=226) received the same initial six-month group behavioral obesity treatment and were then randomized to 1) a novel motivation-focused maintenance program (N=113) or 2) a standard skill-based maintenance approach (N=113). Main Outcome Measure Weight assessed at baseline, 6, and 18 months. Results Both treatment groups (motivation-focused and skill-based) achieved comparable 18-month weight losses (−5.48% for motivation-focused vs −5.55% in skill-based, p=0.98), and both groups lost significantly more than controls (−1.51%; p=.0012 in motivation-focused and .0021 in skill-based). Conclusions A motivation-focused maintenance program offers an alternative, effective approach to weight maintenance expanding available evidence-based interventions beyond traditional skill-based programs.

Abstract

Abstract Many protocols have been used in clinical and research settings for collecting systolic blood pressure (SBP) measurements to calculate the ankle–brachial index (ABI); however, it is not known how useful it is to replicate measurements and which measures best reflect cardiovascular risk. Standardized measurements of ankle and arm SBP from 5140 overweight or obese individuals with type 2 diabetes were used to estimate sources of variation. Measurement characteristics of leg-specific ABI, as calculated using a standard algorithm based on the highest SBP of the dorsalis pedis or posterior tibial arteries, were projected using simulations. Coefficients of variability ranged from 2% to 3% when single SBP measurements were used and ABI was overestimated by 2–3%. Taking two SBP measurements at each site reduced standard errors and bias each by 30–40%. The sensitivity of detecting low ABI ranges exceeded 90% for ABI within 0.05 of the 0.90 clinical cut-point. The average and the minimum of the two (i.e. right and left) leg-specific ABI values had similar U-shaped relationships with Framingham risk scores; however, the average leg ABI had slightly greater precision. Replicating SBP measurements reduces the error and bias of ABI. Averaging leg-specific values may increase power for characterizing cardiovascular disease risk.

Abstract

Self-monitoring promotes behavior changes by promoting awareness of eating habits and creates self-efficacy. It is an important component of the Women's Health Initiative dietary intervention. During the first year of intervention, 74% of the total sample of 19,542 dietary intervention participants self-monitored. As the study progressed the self-monitoring rate declined to 59% by spring 2000. Participants were challenged by inability to accurately estimate fat content of restaurant foods and the inconvenience of carrying bulky self-monitoring tools. In 1996, a Self-Monitoring Working Group was organized to develop additional self-monitoring options that were responsive to participant needs. This article describes the original and additional self-monitoring tools and trends in tool use over time. Original tools were the Food Diary and Fat Scan. Additional tools include the Keeping Track of Goals, Quick Scan, Picture Tracker, and Eating Pattern Changes instruments. The additional tools were used by the majority of participants (5,353 of 10,260 or 52% of participants who were self-monitoring) by spring 2000. Developing self-monitoring tools that are responsive to participant needs increases the likelihood that self-monitoring can enhance dietary reporting adherence, especially in long-term clinical trials.

Abstract

Background Little is known about diet quality with a reduced-energy, low-fat, partial meal replacement plan, especially in individuals with type 2 diabetes. The Action for Health in Diabetes (Look AHEAD) trial implemented a partial meal replacement plan in the Intensive Lifestyle Intervention. Objective To compare dietary intake and percent meeting fat-related and food group dietary recommendations in Intensive Lifestyle Intervention and Diabetes Support and Education groups at 12 months. Design A randomized controlled trial comparing Intensive Lifestyle Intervention with Diabetes Support and Education at 0 and 12 months. Participants/setting From 16 US sites, the first 50% of participants (aged 45 to 76 years, overweight or obese, with type 2 diabetes) were invited to complete dietary assessments. Complete 0- and 12-month dietary assessments (collected between 2001 and 2004) were available for 2,397 participants (46.6% of total participants), with 1,186 randomized to Diabetes Support and Education group and 1,211 randomized to Intensive Lifestyle Intervention group. Main outcome measures A food frequency questionnaire assessed intake: energy; percent energy from protein, fat, carbohydrate, polyunsaturated fatty acids, and saturated fats; trans -fatty acids; cholesterol; fiber; weekly meal replacements; and daily servings from food groups from the Food Guide Pyramid. Statistical analyses performed Mixed-factor analyses of covariance, using Proc MIXED with a repeated statement, with age, sex, race/ethnicity, education, and income controlled. Unadjusted χ 2 tests compared percent meeting fat-related and food group recommendations at 12 months. Results At 12 months, Intensive Lifestyle Intervention participants had a significantly lower fat and cholesterol intake and greater fiber intake than Diabetes Support and Education participants. Intensive Lifestyle Intervention participants consumed more servings per day of fruits; vegetables; and milk, yogurt, and cheese; and fewer servings per day of fats, oils, and sweets than Diabetes Support and Education participants. A greater percentage of Intensive Lifestyle Intervention participants than Diabetes Support and Education participants met fat-related and most food group recommendations. Within Intensive Lifestyle Intervention, a greater percentage of participants consuming two or more meal replacements per day than participants consuming less than one meal replacement per day met most fat-related and food group recommendations. Conclusions The partial meal replacement plan consumed by Intensive Lifestyle Intervention participants was related to superior diet quality.

Abstract

Look AHEAD (Action for Health in Diabetes) was a randomized clinical trial designed to examine the long-term health effects of weight loss in overweight and obese individuals with type 2 diabetes. The primary result was that the incidence of cardiovascular events over a median follow-up of 9.6 years was not reduced in the Intensive Lifestyle Group relative to the control group. This finding is discussed, with emphasis on its implications for design of trials and clinical treatment of obese persons with type 2 diabetes.

Abstract

The authors examined associations of caffeine and caffeinated beverage intakes with blood pressure and with lipoproteins in 5,115 black and white men and women aged 18-30 years during 1985-1986. Caffeine and beverage intakes were not consistently associated with blood pressure in analyses controlling for race, sex, Keys score, sucrose intake, physical activity, oral contraceptive use, body mass index, alcohol use, age, and smoking. Associations of caffeine and beverage intakes with cholesterol, triglycerides, high-density lipoprotein cholesterol, and high-density lipoprotein2 cholesterol were also inconsistent. There is little or no association of caffeine with lipoproteins or with blood pressure in this cohort of healthy young adults.

Abstract

The Coronary Artery Risk Development in (Young) Adults (CARDIA) Study developed and implemented quality control (QC) measures to minimize misclassification associated with dietary data. Manual and automated data inspection were used to monitor quality. Of the 5111 participants who completed a dietary history, 717 (14%) had dietary forms reviewed and 153 (3%) had the interview audiotaped. Results show that for the 717 forms reviewed, the overall form completion error rate was 0.22% and the "critical" error rate (i.e., those errors impacting on nutrient computations) was 0.12%. The proportion of forms free of any type of error increased over time (p less than 0.0001). The discrepancy rate in recording and interviewing methods as estimated from the 153 audiotaped interviews was 0.7%. Inter-interviewer differences were small as indicated by the audiotaped interviews and the proportion of error-free forms completed by interviewers. The results indicate that the dietary data collected in CARDIA were completely and accurately recorded for use in analysis.

Abstract

Behavioral theories can guide clinicians in developing the best strategies for promoting a therapeutic nutritional change. Commonly utilized behavioral models in nutrition interventions in geriatric populations include the Ecological Perspective, the Health Belief Model, the Stages of Change Model, the Theory of Meaningful Learning, the Information Processing Model, and Social Cognitive Theory. Integration of behavioral theories in clinical care can facilitate improved chronic disease self-management by supporting adoption and maintenance of healthful nutritional practices.

Abstract

The Coronary Artery Risk Development in Young Adults (CARDIA) study completed baseline dietary assessment, measurement of body mass index, and lipid and lipoprotein analyses on 5,111 participants. CARDIA includes black and white men and women between 18 and 30 years of age at baseline (1985-1986), recruited in Birmingham, Alabama, Chicago, Illinois, Minneapolis, Minnesota, and Oakland, California. Diet was assessed by a detailed interviewer-administered diet history that measured the usual eating pattern over the past month. Possible sex, race, age, and educational differences in diet, body size, and lipids-lipoproteins were explored. Nutrient analyses indicate that the Keys score, a measure of dietary fat composition, is significantly correlated with plasma cholesterol in older (aged 25-30 years) white men (r = 0.12, p less than 0.01) and older white women (r = 0.12, p less than 0.001). In multiple linear regression analyses, body mass index was positively and significantly associated with total cholesterol and low density lipoprotein cholesterol and inversely associated with high density lipoprotein cholesterol across all race-sex groups. The Keys score was significantly associated with total cholesterol and low density lipoprotein cholesterol in white men and women. Education was associated with high density lipoprotein cholesterol in black and white women and white men. In these young adults, dietary fat intake and body mass index were related to blood lipids in certain subgroups. In black and white men and black women, blood cholesterol increased with age across race-sex groups independently of these covariates. In view of the many factors affecting plasma cholesterol and the limitations of the dietary history method, these cross-sectional data are useful in characterizing diet and lipid differences. There appears to be general disparity between recommended dietary intake of total fat, saturated fat, and other nutrients and actual dietary intake in young adults, regardless of age and educational level.

Abstract

Background Increasingly, genetic specimens are collected to expand the value of clinical trials through study of genetic effects on disease incidence, progression or response to interventions. Purpose and methods We describe the experience obtaining IRB-approved DNA consent forms across the 19 institutions in the Action for Health in Diabetes (Look AHEAD), a clinical trial examining the effect of a lifestyle intervention for weight loss on the risk of serious cardiovascular events among individuals with type 2 diabetes. We document the rates participants provided consent for DNA research, identify participant characteristics associated with consent, and discuss implications for genetics research. Results IRB approval to participate was obtained from 17 of 19 institutions. The overall rate of consent was 89.6% among the 15 institutions that had completed consenting at the time of our analysis, which was higher than reported for other types of cohort studies. Consent rates were associated with factors expected to be associated with weight loss and cardiovascular disease and to affect the distribution of candidate genes. Non-consent occurred more frequently among participants grouped as African-American, Hispanic, female, more highly educated or not dyslipidemic. Limitations The generalizabilty of results is limited by the inclusion/exclusion criteria of the trial. Conclusions Barriers to obtaining consent to participate in genetic studies may differ from other recruitment settings. Because of the potentially complex associations between personal characteristics related to adherence, outcomes and gene distributions, differential rates of consent may introduce biases in estimates of genetic relationships.

Abstract

Objective This study estimates the prevalence of fecal incontinence (FI) in overweight and obese women with urinary incontinence and compares dietary intake in women with and without FI. Study Design A total of 336 incontinent and overweight women in the Program to Reduce Incontinence by Diet and Exercise clinical trial were included. FI was defined as monthly or greater loss of mucus, liquid, or solid stool. Dietary intake was quantified using the Block Food Frequency Questionnaire. Results Women had a mean (± SD) age of 53 ± 10 years, body mass index of 36 ± 6 kg/m 2 , and 19% were African American. Prevalence of FI was 16% (n = 55). In multivariable analyses, FI was independently associated with low fiber intake, higher depressive symptoms, and increased urinary tract symptoms (all P Conclusion Overweight and obese women report a high prevalence of monthly FI associated with low dietary fiber intake. Increasing dietary fiber may be a treatment for FI.

Abstract

Weight loss appears to be an effective method for primary prevention of hypertension. However, the long-term effects of weight loss on blood pressure have not been extensively studied.To present detailed results from the weight loss arm of Trials of Hypertension Prevention (TOHP) II.Multicenter, randomized dinical trial testing the efficacy of lifestyle interventions for reducing blood pressure over 3 to 4 years. Participants in TOHP II were randomly assigned to one of four groups. This report focuses only on participants assigned to the weight loss (n = 595) and usual care control (n = 596) groups.Men and women 30 to 54 years of age who had nonmedicated diastolic blood pressure of 83 to 89 mm Hg and systolic blood pressure less than 140 mm Hg and were 110% to 165% of their ideal body weight at baseline.The weight loss intervention included a 3-year program of group meetings and individual counseling focused on dietary change, physical activity, and social supportWeight and blood pressure data were collected every 6 months by staff who were blinded to treatment assignmentMean weight change from baseline in the intervention group was -4.4 kg at 6 months, -2.0 kg at 18 months, and -0.2 kg at 36 months. Mean weight change in the control group at the same time points was 0.1, 0.7, and 1.8 kg. Blood pressure was significantly lower in the intervention group than in the control group at 6, 18, and 36 months. The risk ratio for hypertension in the intervention group was 0.58 (95% CI, 0.36 to 0.94) at 6 months, 0.78 (CI, 0.62 to 1.00) at 18 months, and 0.81 (CI, 0.70 to 0.95) at 36 months. In subgroup analyses, intervention participants who lost at least 4.5 kg at 6 months and maintained this weight reduction for the next 30 months had the greatest reduction in blood pressure and a relative risk for hypertension of 0.35 (CI, 0.20 to 0.59).Clinically significant long-term reductions in blood pressure and reduced risk for hypertension can be achieved with even modest weight loss.
