Seasonal body mass changes and feed intake in spectacled bears (Tremarctos ornatus) at Zurich Zoological Garden

Many animals display seasonal patterns of behaviour and metabolism that can be also be observed in captivity. During an obesity-control program in Andean bears (Tremarctos ornatus) at Zoo Zurich, a seasonal fluctuation of body mass war observed once ideal body mass had been reached. The focus of this study was the question if metabolism of a male and three female animals was affected by seasonality according to their seasonal breeding behaviour, using data on pelleted food intake (from computer controlled feeders) and body mass (from regular weighing). The pelleted diet in the feeder boxes was provided additionally to a daily ration containing vegetables, fruits, pellets for environmental enrichment, and fish. This daily ration was adjusted, within prescribed limits, by the animal keepers depending on the previous day's consumption. Formulas developed for dogs were used to estimate the metabolizable energy (ME) content of the diet and maintenance requirement of the bears depending on their individual body mass. Energy requirements for minimum walked distances between the feeders was calculated as well as energy requirement for fat accretion or energy gained from body fat by body mass loss. Body mass showed a seasonal fluctuation with maxima in spring and minima in autumn, in contrast to the pattern typically observed in animals from the temperate zone; in the male, the body mass maximum occurred later than in the females. Feed intake from feeder boxes peaked in autumn, at the beginning of body mass gain in the females. These patterns cannot be explained as seasonal adaptations to climatic changes in the zoo environment, but match the natural breeding season of Andean bears in their natural habitat, suggesting genetically fixed photoperiodic clues. The data indicate that body mass fluctuation in a range considered ideal for the species was mostly based on the additional food whose amount was adjusted - within limits - by the keepers on a daily basis. Such adjustment, without incurring the risk of obesity in bears that are known as voracious eaters, is a good example of the skill required in animal husbandry.

Latent class analysis suggests four distinct classes of complementary medicine users among women with breast cancer.

BackgroundBreast cancer patients commonly report using >1 form of complementary and alternative medicine (CAM). However, few studies have attempted to analyze predictors and outcomes of multiple CAM modalities. We sought to group breast cancer patients by clusters of type and intensity of complementary and alternative medicine (CAM) use following diagnosis.MethodsDetailed CAM use following breast cancer diagnosis was assessed in 2002–2003 among 764 female residents of Long Island, New York diagnosed with breast cancer in 1996–1997. Latent class analysis (LCA) was applied to CAM modalities while taking into account frequency and intensities.ResultsFour distinct latent classes of CAM use emerged: 1) “Low-dose supplement users” (40 %), who used only common nutritional supplements; 2) “Vitamin/mineral supplement users” (39 %), using an abundance of supplements in addition to other practices; 3) “Mind-body medicine users” (12 %), with near-universal use of supplements, mind-body medicine techniques, and massage; and 4) “Multi-modality high-dose users” (9 %), who were highly likely to use nearly all types of CAM. Predictors of membership in classes with substantial CAM use included younger age, more education, higher income, Jewish religion, ideal body mass index, higher fruit and vegetable intake, higher levels of physical activity, receipt of adjuvant chemotherapy, and prior use of oral contraceptives.ConclusionsLCA identified important subgroups of breast cancer patients characterized by varying degrees of complementary therapy use. Further research should explore the reproducibility of these classes and investigate the association between latent class membership and breast cancer outcomes.

Prevalence and management of oropharyngeal dysphagia in patients with severe anorexia nervosa: A large retrospective review.

Oropharyngeal dysphagia (OPD) refers to difficulty swallowing food or a liquid bolus from the oral and pharyngeal cavities into the esophagus and increases the risk of possibly life-threatening pneumonia. Little has been reported on OPD in adults with anorexia nervosa (AN). This study includes a description of OPD in severe AN and discusses potentially effective clinical management. Two hundred and six adults with severe AN, admitted over a five-year period to a national referral center specializing in the multidisciplinary medical stabilization of this population, were retrospectively evaluated by electronic database query and manual chart review. All patients whose initial medical assessment triggered a speech-language pathology (SLP) consultation, due to concerns for OPD, were reviewed in detail. Of the 206 total patients, 42 presented with symptoms of OPD and received SLP consultation. In the OPD cohort, 37 (88%) were women, with median age 32 years old, and mean admission weights of 57% ideal body weight (IBW) and body mass index (BMI) of 12 kg/m(2). Compared with those who did not have OPD, OPD patients had significantly lower BMI on admission (12 kg/m(2) vs. 13.1 kg/m(2), p < 0.001), longer stay (21 days vs. 14 days, p < 0.001), and were more medically compromised, including a greater incidence of refeeding hypophosphatemia (60.9% vs. 29.7%, p < 0.004). Clinical awareness of OPD may reduce the incidence of aspiration pneumonia and promote life-saving oral nutrition in patients with severe AN. Proper, timely evaluation and intervention may improve clinical outcomes.

Status of Cardiovascular Health in Chinese Adults

BackgroundCardiovascular disease has become the leading cause of death in China. ObjectivesThe goal of this study was to evaluate the current status of cardiovascular health in Chinese adults. MethodsCardiovascular health data were collected from a nationally representative sample of 96,121 Chinese adults age ≥20 years in 2010. Ideal cardiovascular health was defined according to the American Heart Association’s 2020 Strategic Impact Goals as follows: the simultaneous presence of 4 favorable health behaviors (ideal smoking status, ideal body mass index, physical activity at goal, and healthy dietary habits) and 4 favorable health factors (ideal smoking status, untreated total cholesterol <200 mg/dl, untreated blood pressure <120/<80 mm Hg, and untreated fasting plasma glucose <100 mg/dl) in the absence of a history of cardiovascular disease. ResultsThe estimated percentage of ideal cardiovascular health was 0.2% in the general adult population in China (0.1% in men and 0.4% in women). An estimated 0.7% (0.4% in men and 1.0% in women) of Chinese adults had all 4 ideal health behaviors, and 13.5% (5.0% in men and 22.3% in women) had all 4 ideal health factors. Men most frequently had 3 to 4 ideal components, and women most commonly had 4 to 5 ideal components of the 7 cardiovascular health metrics. Ideal diet (1.6%) was the least common among all cardiovascular health metrics. Female sex and younger age were the 2 most common protective factors for cardiovascular health in Chinese adults. ConclusionsThe percentage of ideal cardiovascular health in Chinese adults is extremely low. Both population-wide and high-risk strategies should be implemented with great effort to promote cardiovascular health in China.

Ideal cardiovascular health: associations with biomarkers and subclinical disease and impact on incidence of cardiovascular disease in the Framingham Offspring Study.

The American Heart Association Cardiovascular Health score (CVH score) is inversely associated with cardiovascular disease (CVD) incidence, but the mechanisms underlying this association warrant exploration. We related the CVH score to circulating biomarkers and prevalent subclinical CVD (defined as ≥1 of the following: increased carotid intima-media thickness or stenosis, left ventricular hypertrophy [by ECG or echocardiography], left ventricular systolic dysfunction, microalbuminuria, and a reduced ankle-brachial index) in 2680 Framingham Study participants (mean age, 58 years; 55% women). After adjustment for age and sex, an ideal CVH score (nonsmoking status, ideal body mass index, regular physical activity, healthy diet, and an optimal profile of serum cholesterol, blood pressure, and glucose; 1 point for each) was associated with higher circulating concentrations of natriuretic peptides (N-terminal pro-atrial natriuretic peptide and B-type natriuretic peptide) and lower blood concentrations of plasminogen activator inhibitor-1, aldosterone, C-reactive protein, D-dimer, fibrinogen, homocysteine, and growth differentiation factor-15 levels (P<0.001 for all), as well as lower odds of subclinical disease (odds ratio, 0.74 per 1-unit increase in CVH score; 95% confidence interval, 0.68-0.80). The incidence of CVD (267 events over 16 years) was inversely associated with the CVH score in age- and sex-adjusted models (hazard ratio, 0.77 per 1-unit increase in CVH score; 95% confidence interval, 0.70-0.86), which was slightly attenuated upon adjustment for biomarkers and subclinical disease (hazard ratio, 0.87; 95% confidence interval, 0.78-0.97). In our prospective community-based study, the inverse association between an ideal cardiovascular health score and CVD incidence was partly attributable to its favorable impact on CVD biomarker levels and subclinical disease.

Prospective relationship of change in ideal cardiovascular health status and arterial stiffness: the Cardiovascular Risk in Young Finns Study.

BackgroundIn 2010, the American Heart Association defined ideal cardiovascular health as the simultaneous presence of 4 favorable health behaviors (nonsmoking, ideal body mass index, physical activity at goal, and dietary pattern that promotes cardiovascular health) and 3 favorable health factors (ideal levels of total cholesterol, blood pressure, and fasting glucose). The association between a change in ideal cardiovascular health status and pulse wave velocity, a surrogate marker of cardiovascular disease, has not been reported.Methods and ResultsThe study cohort consisted of 1143 white adults from the Cardiovascular Risk in Young Finns Study who were followed for 21 years since baseline (1986). This cohort was divided in 2 subgroups: 803 participants (aged 9 to 18 years at baseline) to study the health status change from childhood to adulthood and 340 participants (aged 21 to 24 years at baseline) to study health status change from young adulthood to middle age. The change in the ideal cardiovascular health index was inversely associated with pulse wave velocity (adjusted for age, sex, and heart rate), every 1‐point increase corresponded to a 0.09‐m/s (P<0.001) decrease in pulse wave velocity in both groups. This association remained significant in subgroups based on the ideal cardiovascular health index at baseline.ConclusionsThe change in ideal cardiovascular health status, both from childhood to adulthood and from young adulthood to middle age, was an independent predictor of adult pulse wave velocity. Our results support the concept of ideal cardiovascular health as a useful tool for primordial prevention of cardiovascular disease.

Association of Body Mass Index with Outcomes in Patients with CKD

Obesity is associated with higher mortality in the general population, but this association is reversed in patients on dialysis. The nature of the relationship of obesity with adverse clinical outcomes in nondialysis-dependent CKD and the putative interaction of the severity of disease with this association are unclear. We analyzed data from a nationally representative cohort of 453,946 United States veterans with eGFR<60 ml/min per 1.73 m(2). The associations of body mass index categories (<20, 20 to <25, 25 to <30, 30 to <35, 35 to <40, 40 to <45, 45 to <50, and ≥50 kg/m(2)) with all-cause mortality and disease progression (using multiple definitions, including incidence of ESRD, doubling of serum creatinine, and the slopes of eGFR) were examined in Cox proportional hazards models and logistic regression models. Multivariable adjustments were made for age, race, comorbidities and medications, and baseline eGFR. Body mass index showed a relatively consistent U-shaped association with clinical outcomes, with the best outcomes observed in overweight and mildly obese patients. Body mass index levels <25 kg/m(2) were associated with worse outcomes in all patients, independent of severity of CKD. Body mass index levels ≥35 kg/m(2) were associated with worse outcomes in patients with earlier stages of CKD, but this association was attenuated in those patients with eGFR<30 ml/min per 1.73 m(2). Thus, until clinical trials establish the ideal body mass index, a cautious approach to weight management is warranted in this patient population.

Menstruation disorders in adolescents with eating disorders-target body mass index percentiles for their resolution.

ABSTRACTObjective:To analyse the progression of body mass index in eating disorders and to determine the percentile for establishment and resolution of the disease.Methods:A retrospective descriptive cross-sectional study. Review of clinical files of adolescents with eating disorders.Results:Of the 62 female adolescents studied with eating disorders, 51 presented with eating disorder not otherwise specified, 10 anorexia nervosa, and 1 bulimia nervosa. Twenty-one of these adolescents had menstrual disorders; in that, 14 secondary amenorrhea and 7 menstrual irregularities (6 eating disorder not otherwise specified, and 1 bulimia nervosa). In average, in anorectic adolescents, the initial body mass index was in 75th percentile; secondary amenorrhea was established 1 month after onset of the disease; minimum weight was 76.6% of ideal body mass index (at 4th percentile) at 10.2 months of disease; and resolution of amenorrhea occurred at 24 months, with average weight recovery of 93.4% of the ideal. In eating disorder not otherwise specified with menstrual disorder (n=10), the mean initial body mass index was at 85th percentile; minimal weight was in average 97.7% of the ideal value (minimum body mass index was in 52nd percentile) at 14.9 months of disease; body mass index stabilization occured at 1.6 year of disease; and mean body mass index was in 73rd percentile. Considering eating disorder not otherwise specified with secondary amenorrhea (n=4); secondary amenorrhea occurred at 4 months, with resolution at 12 months of disease (mean 65th percentile body mass index).Conclusion:One-third of the eating disorder group had menstrual disorder – two-thirds presented with amenorrhea. This study indicated that for the resolution of their menstrual disturbance the body mass index percentiles to be achieved by female adolescents with eating disorders was 25–50 in anorexia nervosa, and 50–75, in eating disorder not otherwise specified.

Abstract 339: Association of the American Heart Association’s Life’s Simple 7 Metric for Cardiovascular Health with Risk of Venous Thrombosis: the Reasons for Geographic and Racial Differences in Stroke Cohort

Background The AHA released a metric, Life’s Simple 7 (LS7), in 2010 to track cardiovascular health. The AHA 2020 Goals include improving population levels of LS7 by 20%. LS7 classifies 7 health components into poor, intermediate or ideal levels. The 7 components are physical activity, diet, smoking, body-mass index, glucose, blood pressure and cholesterol. Associations of these individual components with risk of venous thrombosis (VT) vary in the literature, but we hypothesized a decreased risk of VT with favorable LS7 summary scores. Methods We recruited 30,239 black and white participants age ≥45 across the US in 2003-7. With 4.6 years of follow up we validated 278 cases of first-time VT, including deep vein thrombosis and pulmonary embolus. We considered a 14 point summary score for LS7 and divided it into inadequate (0-4 points), average (5-9 points) and optimum (10-14) cardiovascular health. Cox proportional hazards models were used to relate baseline LS7 score to risk of subsequent VT, adjusting for age, sex, race, income, education and region of residence. Results Cases of VT were older and more likely to be male than noncases. Across categories of optimum, average and inadequate baseline health based on the summary LS7 score, the incidence rates of VT were 1.8, 2.1 and 3.1 per 1000 person years, respectively. Compared to those with inadequate health, persons with average health had an adjusted HR of VT of 0.60 (95% CI 0.42-0.84) while those with optimum health had a HR 0.52 (95% CI 0.36-0.77). The HR for a 1 point improvement in overall score (analogous to improvement of one of the 7 factors from poor–&gt;intermediate or intermediate–&gt;ideal) was 0.87 (95% CI 0.81-0.94). The individual factors of LS7 most strongly related to VT risk were ideal physical activity level (HR 0.61, 95% CI 0.46-0.83) and ideal body-mass index (HR 0.42, 95% CI 0.30-0.60); these associations were independent of each other. All associations were similar in blacks and whites. Conclusions A summary measure of cardiovascular health was strongly associated with reduced risk of VT in this US population sample. Results suggest that lifestyle interventions might be effective in reducing incidence of VT, and that achieving AHA’s 2020 Goals will also reduce VT incidence.

Relationship of a desire of thinness and eating behavior among Japanese underweight female students

We conducted a questionnaire survey among Japanese female students to explore the influence of a desire for thinness and dietary behaviors on the development of eating disorders. Self-reported measures of socio-demographic characteristics, body weight perception, height and weight, and dietary and exercise behavior were completed by 631 female university students at 6 universities in Kyoto, Japan. Many students had a desire for thinness (underweight students, 51.7%; normal-weight students, 88.8%), whereas ideal weight and body mass index were lower in the students with a desire for thinness than the students without a desire for thinness, and were also lower in the underweight students than the normal-weight students. The eating attitude test (EAT-26) scores of underweight students with a desire for thinness were higher than those of the normal-weight students with a desire for thinness. As a result of a logistic regression analysis, underweight, desire for thinness, and experience with weight control were positively associated with eating problems. Further, the association of eating problems increased along with the increase in the number of factors (underweight, desire for thinness, and experience with weight control). These results indicate that underweight females have strong associations with eating problems.

Status of Cardiovascular Health in US Adolescents

Background— The American Heart Association recently developed definitions and metrics for monitoring the spectrum of cardiovascular health in adolescents and children. Current nationally representative prevalence estimates according to sex and race/ethnicity are unavailable. Methods and Results— We examined the components of cardiovascular health in 4673 participants aged 12 to 19 years (representing ≈33.2 million US adolescents) from the 2005–2010 National Health and Nutrition Examination Surveys. Population prevalence of individual cardiovascular health behaviors and factors was estimated according to American Heart Association criteria for poor, intermediate, and ideal levels. Ideal blood pressure was most prevalent (males, 78%; females, 90%), whereas a dramatically low prevalence of ideal Healthy Diet Score was observed (males, &lt;1%; females, &lt;1%). Females exhibited a lower prevalence of ideal total cholesterol (65% versus 72%, respectively) and ideal physical activity levels (44% versus 67%, respectively) yet a higher prevalence of ideal blood glucose (89% versus 74%, respectively) compared with males. Approximately two thirds of adolescents exhibited ideal body mass index (males, 66%; females, 67%) and ideal smoking status (males, 66%; females, 70%). Less than 50% of adolescents exhibited ≥5 ideal cardiovascular health components (45%, males; 50%, females). Prevalence estimates according to sex were consistent across race/ethnic groups. Conclusions— The low prevalence of ideal cardiovascular health behaviors in US adolescents, particularly physical activity and dietary intake, will likely contribute to a worsening prevalence of obesity, hypertension, hypercholesterolemia, and dysglycemia as the current US adolescent population reaches adulthood. Population-wide emphasis on establishment of ideal cardiovascular health behaviors early in life is essential for maintenance of ideal cardiovascular health throughout the lifespan.

A Pilot Study of an Acceptance-Based Separated Family Treatment for Adolescent Anorexia Nervosa

The treatment of adolescent anorexia nervosa (AN) has improved significantly with the increased emphasis on family-based intervention. Yet despite advances, a substantial number of adolescents do not respond optimally to existing treatment models and thus there is a need for treatment alternatives that address barriers to recovery. We developed and piloted an acceptance-based separated family treatment (ASFT) with 6 adolescents with AN or subthreshold AN (eating disorder not otherwise specified, with the primary symptoms of restriction and severe weight loss). Treatment acceptability was adequate. Overall, parents rated the treatment as credible and expected improvement in their child's condition. Five of the 6 adolescents treated with ASFT restored weight to their ideal body mass index as indicated by age, height, and sex and determined by individual growth charts. Many demonstrated improved psychological health and adaptive functioning. There was evidence of broad effects, with parents reporting decreased anxiety and caregiver burden. ASFT holds promise as a treatment option for AN. The efficacy of this therapeutic approach should be tested in larger trials and compared to current family-based interventions to determine unique effects.

The effect of positive end-expiratory pressure on pulse pressure variation

AbstractObjectives: To determine the effect of different levels of positive end-expiratory pressure (PEEP) on pulse pressure variation (PPV).Design: An observational study.Setting: Operating theatres of a tertiary training hospital.Subjects: Ventilated patients who required intra-arterial blood pressure monitoring.Outcome measures: PPV during different levels of PEEP.Method: Patients were anaesthetised by means of a standard technique and ventilated with a tidal volume of 9 ml/kg ideal body mass. The PPV was calculated at PEEP levels of 2, 5, 8 and 10 cmH2O. PPV was compared at the various PEEP levels.Results: PPV at a PEEP of 8 cmH2O and 10 cmH2O was significantly larger than that at 2 cmH2O (p-value < 0.001). PPV at a PEEP of 10 cmH2O was significantly larger than that at 8 cmH2O (p-value < 0.001). PPV at a PEEP of 8 cmH2O was larger than that at 5 cmH2O (p-value = 0.002). PPV at a PEEP of 2 and 5 cmH2O did not differ significantly (p-value = 0.194).Conclusion: We have demonstrated that, in patients wit...

Prediction of Clearance and Volume of Distribution in the Obese from Normal Weight Subjects

The principles of allometry can be applied within a given species (intra-species scaling), for example extrapolation of pharmacokinetic parameters from adults to adolescents and older children (>5 years of age). Similarly, allometric scaling may also be used to predict pharmacokinetic parameters from normal weight subjects to the obese. The objective of this investigation was to evaluate the predictive performance of several allometric methods for the prediction of drug clearance (CL) and volume of distribution (V(d)) in the obese from normal weight subjects. CL and V(d) values for 12 drugs for obese and normal weight subjects were obtained from the literature. Three methods (simple allometry and fixed exponents of 0.75 and 1.0) and two methods (simple allometry and a fixed exponent of 1.0) were used to predict CL and V(d), respectively, using total body weight in the obese from normal weight subjects. When data were available, ideal body weight, percentage ideal body weight and body mass index were also used for prediction purposes. The results of the study indicated that CL could be predicted with accuracy in the obese from normal weight subjects using total body weight and simple allometry as well as fixed exponent of 0.75. The prediction of V(d) in the obese from normal weight subjects was less accurate than the prediction of CL in this population. For the prediction of CL and V(d) in the obese, simple allometry performed better than the fixed exponent of 0.75 or 1.0, respectively. The study indicated that allometric scaling can be applied to predict CL in the obese from normal weight subjects with high accuracy. The predicted CL can then be used to select a dose to initiate a clinical trial (pharmacokinetics, safety and efficacy).

Status of Cardiovascular Health in US Adults

The American Heart Association's 2020 Strategic Impact Goals define a new concept, cardiovascular (CV) health; however, current prevalence estimates of the status of CV health in US adults according to age, sex, and race/ethnicity have not been published. We included 14 515 adults (≥20 years of age) from the 2003 to 2008 National Health and Nutrition Examination Surveys. Participants were stratified by young (20-39 years), middle (40-64 years), and older (≥65 years) ages. CV health behaviors (diet, physical activity, body mass index, smoking) and CV health factors (blood pressure, total cholesterol, fasting blood glucose, smoking) were defined as poor, intermediate, or ideal. Fewer than 1% of adults exhibited ideal CV health for all 7 metrics. For CV health behaviors, nonsmoking was most prevalent (range, 60.2%-90.4%), whereas ideal Healthy Diet Score was least prevalent (range, 0.2%-2.6%) across groups. Prevalences of ideal body mass index (range, 36.5%-45.3%) and ideal physical activity levels (range, 50.2%-58.8%) were higher in young adults compared with middle or older ages. Ideal total cholesterol (range, 23.7%-36.2%), blood pressure (range, 11.9%-16.3%), and fasting blood glucose (range, 31.2%-42.9%) were lower in older adults compared with young and middle-aged adults. Prevalence of poor CV health factors was lowest in young age but higher at middle and older ages. Prevalence estimates by age and sex were consistent across race/ethnic groups. These prevalence estimates of CV health represent a starting point from which effectiveness of efforts to promote CV health and prevent CV disease can be monitored and compared in US adult populations.
