ABSTRACT

OBJECTIVE: Cognitive-behavioral therapy (CBT)-therapist-led (CBTth) and guided-self-help (CBTgsh)-has efficacy for binge-eating disorder (BED) but many patients do not benefit sufficiently. We examined predictors and moderators for these two CBT methods. METHOD: Data were aggregated from randomized controlled trials (RCTs) testing psychosocial treatments for BED in the U.S. Predictors and moderators of outcomes (treatment completion and binge-eating remission) were examined in N = 457 participants who received either CBTgsh (N = 164) or CBTth (N = 293). RESULTS: Analyses, adjusting for demographic/clinical variables, indicated CBTth was significantly superior to CBTgsh for treatment completion (odds ratio [OR] = 20.0) and remission (OR = 14.6). For remission, analyses revealed significant predictors (age, treatment length, Weight Concern), a moderator (weight concern [OR = 5.13]), and a significant interaction between CBT-type and treatment length (OR = 2.66). For CBTgsh, longer treatment was associated with less remission, whereas for CBTth, longer treatment was associated with greater remission. For CBTgsh, 44.1% with low weight concern versus 56.3% with high weight concern achieved remission whereas for CBTth, 43.5% with high weight concern and 61.0% with low weight concern achieved remission. DISCUSSION: Analyses of aggregated RCT BED data, adjusting for demographic/clinical characteristics, indicated superiority (large effect-sizes) in treatment outcomes of CBTth over CBTgsh and that Weight Concern moderated outcomes.

ABSTRACT

BACKGROUND: The North American Pediatric Craniofacial Collaborative Group (PCCG) established the Pediatric Craniofacial Surgery Perioperative Registry to evaluate outcomes in infants and children undergoing craniosynostosis repair. The goal of this multicenter study was to utilize this registry to assess differences in blood utilization, intensive care unit (ICU) utilization, duration of hospitalization, and perioperative complications between endoscopic-assisted (ESC) and open repair in infants with craniosynostosis. We hypothesized that advantages of ESC from single-center studies would be validated based on combined data from a large multicenter registry. METHODS: Thirty-one institutions contributed data from June 2012 to September 2015. We analyzed 1382 infants younger than 12 months undergoing open (anterior and/or posterior cranial vault reconstruction, modified-Pi procedure, or strip craniectomy) or endoscopic craniectomy. The primary outcomes included transfusion data, ICU utilization, hospital length of stay, and perioperative complications; secondary outcomes included anesthesia and surgical duration. Comparison of unmatched groups (ESC: N = 311, open repair: N = 1071) and propensity score 2:1 matched groups (ESC: N = 311, open repair: N = 622) were performed by conditional logistic regression analysis. RESULTS: Imbalances in baseline age and weight are inherent due to surgical selection criteria for ESC. Quality of propensity score matching in balancing age and weight between ESC and open groups was assessed by quintiles of the propensity scores. Analysis of matched groups confirmed significantly reduced utilization of blood (26% vs 81%, P < .001) and coagulation (3% vs 16%, P < .001) products in the ESC group compared to the open group. Median blood donor exposure (0 vs 1), anesthesia (168 vs 248 minutes) and surgical duration (70 vs 130 minutes), days in ICU (0 vs 2), and hospital length of stay (2 vs 4) were all significantly lower in the ESC group (all P < .001). Median volume of red blood cell administered was significantly lower in ESC (19.6 vs 26.9 mL/kg, P = .035), with a difference of approximately 7 mL/kg less for the ESC (95% confidence interval for the difference, 3-12 mL/kg), whereas the median volume of coagulation products was not significantly different between the 2 groups (21.2 vs 24.6 mL/kg, P = .73). Incidence of complications including hypotension requiring treatment with vasoactive agents (3% vs 4%), venous air embolism (1%), and hypothermia, defined as <35°C (22% vs 26%), was similar between the 2 groups, whereas postoperative intubation was significantly higher in the open group (2% vs 10%, P < .001). CONCLUSIONS: This multicenter study of ESC versus open craniosynostosis repair represents the largest comparison to date. It demonstrates striking advantages of ESC for young infants that may result in improved clinical outcomes, as well as increased safety.

ABSTRACT

OBJECTIVE: A subset of individuals with bulimia nervosa (BN) have borderline personality disorder (BPD) symptoms, including chronic negative affect and interpersonal problems. These symptoms predict poor BN treatment outcome in some studies. The broad version of Enhanced Cognitive Behavior Therapy (CBT-E) was developed to address co-occurring problems that interfere with treatment response. The current study investigated the relative effects, predictors, and moderators of CBT-E for BN with BPD and co-occurring mood/anxiety disorders. METHOD: Fifty patients with BN and threshold or sub-threshold BPD and current or recent Axis I mood or anxiety disorders were randomly assigned to receive focused CBT-E (CBT-Ef) or broad CBT-E (CBT-Eb) specifically including an interpersonal module and additional attention to mood intolerance. RESULTS: Forty-two percent of the sample reported remission from binge eating and purging at termination. Significant changes across symptom domains were observed at termination and at 6-month follow-up. Though CBT-Ef predicted good outcomes in multivariate models, the severity of affective/interpersonal problems moderated treatment effects: participants with higher severity showed better ED outcomes in CBT-Eb, whereas those with lower severity showed better outcomes in CBT-Ef. Severity of affective/interpersonal BPD symptoms at baseline predicted negative outcomes overall. Follow-up BPD affective/interpersonal problems were predicted by baseline affective/interpersonal problems and by termination EDE score. DISCUSSION: This study supports the utility of CBT-E for patients with BN and complex comorbidity. CBT-Ef appears to be more efficacious for patients with relatively less severe BPD symptoms, whereas CBT-Eb appears to be more efficacious for patients with more severe BPD symptoms.

ABSTRACT

OBJECTIVE: The aim of the study was to examine gender differences in baseline and outcome variables in clinical trials for binge eating disorder (BED). METHOD: Data from 11 randomized controlled psychosocial treatment studies were aggregated (N = 1,325: 208 male, 1,117 female). Baseline and outcome symptoms were assessed via the interview and questionnaire versions of the Eating Disorder Examination (EDE). Multilevel analyses were conducted investigating gender differences at baseline and posttreatment, defined as EDE scores, objective binge episode (OBE) reduction, and OBE remission at termination. RESULTS: Few males from low socioeconomic status or minority groups participated in the outcome studies. Males reported significantly lower EDE global, shape, weight, and eating concerns at baseline. No main effects of gender were found in treatment outcome scores when controlling for baseline differences; however, baseline EDE global score (which showed gender differences at baseline) and OBEs directly predicted outcome for both males and females. A significant interaction between gender, treatment length, and shape/weight concerns indicated that males with lower shape/weight concerns achieved OBE remission in shorter treatments, whereas men with high shape/weight concerns and women with either high or low shape/weight concerns were more likely to achieve OBE remission in treatments of longer duration. CONCLUSIONS: These results suggest BED treatment studies must improve their recruitment of men and appeal to men with lower shape/weight concerns. Additionally, longer term treatments, although more efficacious for women and men with more severe shape/weight concerns, may not be necessary for men with low shape/weight concerns.

ABSTRACT

Objective was to test feasibility and preliminary efficacy of a culturally adapted cognitive-behavioral self-help program to treat binge eating and related problems in Mexican Americans. Participants were 31 women recruited from the Los Angeles area and diagnosed with binge eating disorder, recurrent binge eating, or bulimia nervosa. Participants completed a culturally adapted version of a CBT-based self-help program with 8 guidance sessions over a 3-month period. Treatment efficacy was evaluated in terms of binge eating, psychological functioning, and weight loss. Intent-to-treat analyses revealed 35.5% abstinence from binge eating at posttreatment and 38.7% diagnostic remission. Results indicated significant pretreatment to posttreatment improvement on distress level, BMI, eating disorder psychopathology, and self-esteem. Satisfaction with the program was high. Findings demonstrate that the program is acceptable, feasible, and efficacious in reducing binge eating and associated symptoms for Mexican American women. Study provides "proof of concept" for implementation of culturally adapted forms of evidence-based programs.

ABSTRACT

The reported incidence of venous thromboembolism (VTE) in children has increased dramatically over the past decade, and the primary risk factor for VTE in neonates and infants is the presence of a central venous catheter (CVC). Although the associated morbidity and mortality are significant, very few trials have been conducted in children to guide clinicians in the prophylaxis, diagnosis, and treatment of CVC-related VTE. Furthermore, pediatric guidelines for prophylaxis and management of VTE are largely extrapolated from adult data. How then should the anesthesiologist approach central access in children of different ages to lessen the risk of CVC-related VTE or in children with prior thrombosis and vessel occlusion? A comprehensive review of the pediatric and adult literature is presented with the goal of assisting anesthesiologists with point-of-care decision-making regarding the risk factors, diagnosis, and treatment of CVC-related VTE. Illustrative cases are also provided to highlight decision-making in varying situations. The only risk factor strongly associated with CVC-related VTE formation in children is the duration of the indwelling CVC. Several other factors show a trend toward altering the incidence of CVC-related VTE formation and may be under the control of the anesthesiologist placing and managing the catheter. In particular, because children with VTE may live decades with its sequelae and chronic vein thrombosis, careful consideration of lessening the risk of VTE is warranted in every child. Further studies are needed to form a clearer understanding of the risk factors, prophylaxis, and management of CVC-related VTE in children and to guide the anesthesiologist in lessening the risk of VTE.

ABSTRACT

OBJECTIVE: Binge eating disorder (BED) is prevalent among individuals from minority racial/ethnic groups and among individuals with lower levels of education, yet the efficacy of psychosocial treatments for these groups has not been examined in adequately powered analyses. This study investigated the relative variance in treatment retention and posttreatment symptom levels accounted for by demographic, clinical, and treatment variables as moderators and predictors of outcome. METHOD: Data were aggregated from 11 randomized, controlled trials of psychosocial treatments for BED conducted at treatment sites across the United States. Participants were N = 1,073 individuals meeting criteria for BED including n = 946 Caucasian, n = 79 African American, and n = 48 Hispanic/Latino participants. Approximately 86% had some higher education; 85% were female. Multilevel regression analyses examined moderators and predictors of treatment retention, Eating Disorder Examination (EDE) global score, frequency of objective bulimic episodes (OBEs), and OBE remission. RESULTS: Moderator analyses of race/ethnicity and education were nonsignificant. Predictor analyses revealed African Americans were more likely to drop out of treatment than Caucasians, and lower level of education predicted greater posttreatment OBEs. African Americans showed a small but significantly greater reduction in EDE global score relative to Caucasians. Self-help treatment administered in a group showed negative outcomes relative to other treatment types, and longer treatment was associated with better outcome. CONCLUSIONS: Observed lower treatment retention among African Americans and lesser treatment effects for individuals with lower levels of educational attainment are serious issues requiring attention. Reduced benefit was observed for shorter treatment length and self-help administered in groups.

ABSTRACT

OBJECTIVE: Recent studies suggest that binge eating disorder (BED) is as prevalent among African American and Hispanic Americans as among Caucasian Americans; however, data regarding the characteristics of treatment-seeking individuals from racial and ethnic minority groups are scarce. The purpose of this study was to investigate racial/ethnic differences in demographic characteristics and eating disorder symptoms in participants enrolled in treatment trials for BED. METHOD: Data from 11 completed randomized, controlled trials were aggregated in a single database, the Clinical Trials of Binge Eating Disorder (CT-BED) database, which included 1,204 Caucasian, 120 African American, and 64 Hispanic participants assessed at baseline. Age, gender, race/ethnicity, education, body mass index (BMI), binge eating frequency, and Eating Disorder Examination (EDE) Restraint, Shape, Weight, and Eating Concern subscale scores were examined. RESULTS: Mixed model analyses indicated that African American participants in BED treatment trials had higher mean BMI than Caucasian participants, and Hispanic participants had significantly greater EDE shape, weight, and eating concerns than Caucasian participants. No racial or ethnic group differences were found on the frequency of binge eating episodes. Observed racial/ethnic differences in BED symptoms were not substantially reduced after adjusting for BMI and education. Comparisons between the CT-BED database and epidemiological data suggest limitations to the generalizability of data from treatment-seeking samples to the BED community population, particularly regarding the population with lower levels of education. CONCLUSIONS: Further research is needed to assess alternative demographic, psychological, and culturally specific variables to better understand the diversity of treatment-seeking individuals with BED.

ABSTRACT

Few studies have explored the relationship between sugar content in cereal and health outcome among children and adolescents. This study was designed to investigate the associations between ready-to-eat cereals, categorized by sugar content, with weight indicators and nutrient intake profiles. Data collected from 6- to 18-year-old US children and adolescents (N = 9660) in the National Health and Nutrition Examination Survey 2001-06 were used to analyze cereal consumption. Body mass index (BMI), BMI-for-age, waist-to-height ratio, percent overweight or obese, mean day-1 intake, and usual daily intake of macronutrients and micronutrients were the dependent variables; day-1 cereal intake, categorized by tertiles of sugar content, was the main independent variable. Weighted regression with adjustment for the survey design was used to model the dependent variables as a function of day-1 cereal intake, adjusting for age group, sex, race/ethnicity, total day-1 intake of energy, calcium and sugar, the Healthy Eating Index-2005 total score, and household income. For all tertiles of sugar classifications of cereal, children who consumed cereal had significantly lower BMI compared with children who consumed no cereal (P's < .05). Similarly, when compared with children who consumed no cereal, those who ate cereal consumed significantly less fat and cholesterol and significantly more carbohydrates, sugar, whole grains, vitamin A, thiamin, riboflavin, niacin, vitamin B(6), folic acid, vitamin B(12), vitamin C, calcium, magnesium, iron, and zinc. Lower weight and positive nutrient profiles were associated with cereal consumption regardless of sugar content.

ABSTRACT

OBJECTIVE: To examine the effects of a multi-component, theory-based, 2.5-year intervention on children's fruit and vegetable consumption, preferences, knowledge and body mass index. METHODS: Four inner city elementary schools in the Northeastern United States were randomized to an intervention (n=149) or control group (n=148) in 2005. Fruit and vegetable consumption during school lunch (measured by plate waste), preferences, and knowledge, as well as body mass index, were assessed five times across 3.5 years (pre-intervention, spring 2006, 2007, 2008 and 2009). Hierarchical linear modeling was used to analyze program outcomes. RESULTS: At the first post-test assessment, children in the experimental group ate 0.28 more servings/lunch of fruit and vegetable relative to children in the control group and changes in fruit and vegetable consumption were found in each year throughout the program. However, this effect declined steadily across time so that by the delayed one-year follow-up period there was no difference between the groups in fruit and vegetable consumption. There were persistent intervention effects on children's knowledge. There were no effects on fruit and vegetable preferences and body mass index throughout the study. CONCLUSION: Although there was initial fruit and vegetable behavior change, annual measurements indicated a gradual decay of behavioral effects. These data have implications for the design of school-based fruit and vegetable interventions.

ABSTRACT

OBJECTIVE: To examine the association between cereal consumption and cardiovascular risk factors including waist, height, total cholesterol, LDL cholesterol and HDL cholesterol in a sample of adolescent girls. DESIGN: Longitudinal study. SETTING: The study was conducted from 1987 to 1997 and data were collected at three study sites (University of California at Berkeley, University of Cincinnati and Westat Inc., Rockville, MD, USA). Mixed models were used to estimate the association between the number of days of eating cereal and these four outcome variables. SUBJECTS: Girls (n 2371) who participated in the 10-year National Heart, Lung, and Blood Growth and Health Study (NGHS) and completed a 3 d food diary in years 1-5 and 7, 8 and 10. RESULTS: Adolescent girls who ate cereal more often had lower waist-to-height ratio (P<0.005), lower total cholesterol (P<0.05) and lower LDL cholesterol (P<0.05), taking into account sociodemographic variables, physical activity levels and total energy intake. CONCLUSIONS: Findings suggest that cereal consumption is associated with markers of cardiovascular risk and that childhood patterns of consumption may influence the development of risk factors later in adolescence.

ABSTRACT

OBJECTIVE: This study examined the longitudinal effects of a school-based program on kindergarten and first grade children's fruit and vegetable (F&V) consumption. METHODS: The program included lunchroom, classroom, school-wide, and family components. The primary dependent variable, F&V consumed at lunch, was assessed using weighed plate waste. Hierarchical linear models were used to analyze the differences between intervention and control groups and to account for repeated measurements. RESULTS: Children in the experimental group consumed more F&V (F = 29 g; V = 6 g; 0.43 portions/lunch; 0.28 servings/lunch) at the end of Year 1 compared with children in the control group. At the end of Year 2, children in the experimental group consumed more fruit (21 g; 0.23 portions/lunch; 0.15 servings/lunch), but not more vegetables compared with children in the control group. CONCLUSIONS: The intervention resulted in increased F&V consumption, with more pronounced and enduring effects for fruits than vegetables.

ABSTRACT

OBJECTIVE: Low intakes of micronutrients among adolescents may be linked to long-term health risks, especially in African-American girls. This report describes intake of key micronutrients relative to the Dietary Reference Intakes in a sample of African-American and white girls. DESIGN: Longitudinal analyses used data from 3-day food records collected in the National Heart, Lung, and Blood Institute Growth and Health Study. SUBJECTS/SETTING: Subjects included 1,166 white and 1,213 African-American girls (aged 9 to 18 years). MAIN OUTCOME MEASURES: Estimated usual daily intakes of vitamins A, E, C, D, B-6, B-12, magnesium, folate, calcium, and zinc were compared to the Adequate Intake (for vitamin D and calcium) or the Estimated Average Requirement (EAR) (all other micronutrients). STATISTICAL ANALYSES PERFORMED: Usual daily intake of each micronutrient was estimated. For nutrients with an EAR, the EAR cut-point method was used to assess the prevalence of low nutrient intakes. Mixed models were used to identify age and racial differences in usual daily intake of each nutrient. RESULTS: African-American girls consumed less vitamin A and D, calcium, and magnesium compared to white girls. Regardless of race, a substantial percentage of girls had intakes below the EAR: vitamin E (81.2% to 99.0%), magnesium (24.0% to 94.5%), folate (46.0% to 87.3%). Intakes of vitamins A, D, and C; calcium; and magnesium decreased across years. As girls aged, there was an increasing proportion with intakes below the EAR for vitamins A, C, B-6, and B-12. CONCLUSIONS: Food and nutrition professionals should continue to educate adolescent girls, especially those who are African American, about the importance of a nutrient-dense diet for optimum health.

ABSTRACT

OBJECTIVE: To estimate the prevalence and incidence of overweight in African-American and Caucasian girls, and to examine associations between adolescent overweight and cardiovascular disease (CVD) risk factors. STUDY DESIGN: In the National Heart, Lung and Blood Institute Growth and Health Study (NGHS), annual measurements were obtained from girls followed longitudinally between age 9 or 10 and 18 years; self-reported measures were obtained at age 21 to 23 years. A total of 1166 Caucasian girls and 1213 African-American girls participated in the study. Childhood overweight as defined by the Centers for Disease Control and Prevention (CDC) was the independent variable of primary interest. Measured outcomes included blood pressure and lipid levels. RESULTS: Rates of overweight increased through adolescence from 7% to 10% in the Caucasian girls and from 17% to 24% in the African-American girls. The incidence of overweight was greater at age 9 to 12 than in later adolescence. Girls who were overweight during childhood were 11 to 30 times more likely to be obese in young adulthood. Overweight was significantly associated with increased percent body fat, sum of skinfolds and waist circumference measurements, and unhealthful systolic and diastolic blood pressure, high-density lipoprotein cholesterol, and triglyceride levels. CONCLUSION: A relationship between CVD risk factors and CDC-defined overweight is present at age 9.

ABSTRACT

School connectedness includes liking school and positive relations with teachers and peers. School connectedness is associated with a variety of positive health outcomes. The goal of this study was to identify characteristics of students, schools, and school neighborhoods that are related to school connectedness. In the Health Behavior in School-Aged Children (HBSC) Study, school connectedness was reported by 13,207 students (grades 6-10) in 340 schools. HBSC measured a variety of student characteristics. Characteristics of schools were culled from data maintained by Quality Education Data, and school neighborhood characteristics were derived from the 2000 decennial census. Associations between connectedness and student, school, and school neighborhood characteristics were estimated using hierarchical linear models. Characteristics of students, schools, and school neighborhoods were associated with school connectedness. Connectedness was greater among younger students, females, students with better academic performance and greater extracurricular involvement, students with greater self-rated physical attractiveness, students with more friends, students from 2-parent families, and students whose parents were more involved with school. Connectedness was greater in smaller schools, more racially homogeneous schools, and schools with more students from relatively wealthy households. School connectedness was higher in neighborhoods with a greater percentage of non-US citizens. As the percent of renters in the neighborhood increased beyond 20%, school connectedness tended to decrease. The findings point to possible strategies for fostering school connectedness.

ABSTRACT

OBJECTIVES: The purpose of this study is to validate the accuracy of multidetector computed tomography (MDCT) to measure differences in regional myocardial perfusion during adenosine stress in a canine model of left anterior descending (LAD) artery stenosis, during first-pass, contrast-enhanced helical MDCT. BACKGROUND: Myocardial perfusion imaging by MDCT may have significant implications in the diagnosis and treatment of coronary artery disease. METHODS: Eight dogs were prepared with a LAD stenosis, and contrast-enhanced MDCT imaging was performed 5 min into adenosine infusion (0.14 to 0.21 mg/kg/min). Images were analyzed using a semiautomated approach to define the regional signal density (SD) ratio (myocardial SD/left ventricular blood pool SD) in stenosed and remote territories, and then compared with microsphere myocardial blood flow (MBF) measurements. RESULTS: Mean MBF in stenosed versus remote territories was 1.37 +/- 0.46 ml/g/min and 1.29 +/- 0.48 ml/g/min at baseline (p = NS) and 2.54 +/- 0.93 ml/g/min and 8.94 +/- 5.74 ml/g/min during adenosine infusion, respectively (p < 0.05). Myocardial SD was 92.3 +/- 39.5 HU in stenosed versus 180.4 +/- 41.9 HU in remote territories (p < 0.001). There was a significant linear association of the SD ratio with MBF in the stenosed territory (R = 0.98, p = 0.001) and between regional myocardial SD ratio and MBF <8 ml/g/min, slope = 0.035, SE = 0.007, p < 0.0001. Overall, there was a significant non-linear relationship over the range of flows studied (LR chi-square [2 degrees of freedom] = 31.8, p < 0.0001). CONCLUSIONS: Adenosine-augmented MDCT myocardial perfusion imaging provides semiquantitative measurements of myocardial perfusion during first-pass MDCT imaging in a canine model of LAD stenosis.

ABSTRACT

OBJECTIVE: To examine longitudinal changes in daily fruit and vegetable consumption among black and white adolescent girls and calculate the percent of girls who met the Healthy People 2010 recommendations. METHODS: Girls (1186 black and 1126 white) who participated in the National Heart, Lung, and Blood Institute Growth Health Study (NGHS) were included if they had completed a 3-day food diary for at least one of six annual assessments visits, beginning at ages 11 or 12. Mixed models estimated the association of visit and race with (a) average daily consumption of fruits and vegetables and (b) the probability of meeting intake recommendations on one or more out of 3 days. RESULTS: For girls of both races, fruit and vegetable consumption increased with age; white girls showed a greater increase in fruit and nutrient-rich vegetable intake than black girls. Across visits, girls consumed considerably fewer than the recommended daily servings of fruits (1.0-1.5), vegetables (1.7-2.5), or nutrient-rich vegetables (0.25). Most girls (95%) failed to meet Healthy People 2010 recommendations. CONCLUSIONS: Public health efforts are needed to meet Healthy People 2010 objectives.
