RESUMEN

A 1-year-old Miniature Horse filly was presented for chronic lethargy and hyporexia. Elevated liver enzymes, bile acids, and ammonia were noted on bloodwork. The primary differential diagnosis was a portosystemic shunt (PSS). Three-phase computed tomographic angiography findings were consistent with a transhepatic portosystemic shunt. Percutaneous liver biopsy confirmed severe diffuse hepatic changes, most likely due to chronic pyrrolizidine alkaloid toxicosis, and medical management was elected. Based on an extensive literature review, this is the first report of a transhepatic portosystemic collateral vessel in a horse. Computed tomographic angiography is feasible and useful for the diagnosis of PSS in miniature horses.

RESUMEN

Stress is linked to emotional eating among adolescents, which in turn increases risk for overweight/obesity (OW/OB) development and continuation. There is a lack of research disentangling chronic and acute stress as predictors of adolescent emotional eating. Further, there is a corresponding need to understand the effects of acute physiological stress reactivity within the context of adolescent emotional eating. The primary aim of this study was to examine the impact of cortisol stress reactivity on emotional eating in adolescents, above and beyond the effects of perceived chronic stress. The impact of subjective stress reactivity was also explored. Adolescents' (N = 49) intake of highly palatable snack foods was measured on separate control and stress-induction (following the Trier Social Stress Test for Children) days. A multi-method approach was used to assess objective (caloric intake) and subjective (self-report) emotional eating. Results indicated that greater cortisol reactivity, but not subjective stress reactivity, predicted subjective emotional eating, beyond the impact of chronic stress. Neither chronic stress nor subjective or objective stress reactivity predicted objective emotional eating following stress-induction. Findings point to the role of chronic stress and cortisol reactivity as risks for greater perceived emotional eating among adolescents, while elucidating differences between perceived and objective emotional eating. Future research should explore how chronic versus acute stress differentially contribute to adolescent weight management.

RESUMEN

Evaluation of brain disease in veterinary patients uses a wide variety of MRI sequences. A shortened protocol that maintains consistency of interpretation would reduce radiologist reporting time, patient anesthetic time, and client cost. The aims of this retrospective, methods comparison, observer agreement study were to evaluate whether abbreviated MRI protocols alter differential diagnoses and recommendations compared to our institution's standard protocol; evaluate interobserver agreement on standard brain MRIs; and assess whether differential diagnoses change after postcontrast images. Normal and pathologic canine and feline brain MRIs were retrieved from hospital archives. Three protocols were created from each: a 5-sequence noncontrast enhanced Fast Brain Protocol 1 (FBP1); a 6-sequence contrast-enhanced Fast Brain Protocol 2 (FBP2); and an 11-sequence standard brain protocol (SBP). Three blinded veterinary radiologists interpreted FBP images for 98 cases (1 reader/case) and SBP images for 20 cases (3 readers/case). A fourth observer compared these interpretations to the original MRI reports (OMR). Overall agreement between FBPs and OMR was good (k = 0.75) and comparable to interobserver agreement for multiple reviews of SBP cases. Postcontrast images substantially altered conclusions in 17/97 cases (17.5%), as well as improved interobserver agreement compared to noncontrast studies. The conclusions reached with shortened brain protocols were comparable to those of a full brain study. The findings supported the use of a 6-sequence brain MRI protocol (sagittal T2-weighted [T2w] TSE; transverse T2w turbo spin echo fluid-attenuated inversion recovery, T2*-weighted gradient recalled echo, T1-weighted spin echo, and diffusion weighted imaging/apparent diffusion coefficient; and postcontrast transverse T1-weighted spin echo) for dogs and cats with suspected intracranial disease.

RESUMEN

Loss of control (LOC) eating is prevalent among adolescents and has been related to significant mental and physical health concerns. A growing body of research suggests that youth from lower income households are at risk for LOC eating. Food insecurity is an understudied contextual factor that may compound the risk for LOC eating in adolescents from low-income backgrounds. The present study sought to: 1) clarify the association between food insecurity and LOC eating among adolescents; and 2) examine whether household food insecurity moderated the association between income-to-needs and LOC eating. As part of a laboratory-based study, adolescents ages 12-17 (N = 60; 33% from low-income households; 53.3% female) completed the Eating Disorder Examination-Questionnaire to measure LOC eating. Parents reported the household food insecurity status and household income, used to calculate income-to-needs ratio. Higher household food insecurity was positively associated with adolescent LOC eating (b = 0.662, t(59) = 5.09, p < .01), after controlling for adolescent BMI percentile, race, ethnicity, biological sex, and age. Food insecurity significantly moderated the association between income-to-needs and LOC eating, ΔF(1,56) = 11.99, p < .01, with the interaction effect explaining an additional 12% of variance. Specifically, lower household income-to-needs was associated with greater LOC eating among adolescents at higher levels of household food insecurity. This finding expands upon prior work by highlighting specific socioeconomic factors that place youth from low-income backgrounds at even greater risk for negative health outcomes. Future research is needed to understand potential ways to intervene for adolescents to prevent future LOC eating in the context of food insecurity.

RESUMEN

Little is known about what factors influence a caregiver to use controlling feeding practices with adolescents. The present study examines potential predictors (e.g., parent and child eating, parent and child weight, and the home environment) of the use of controlling feeding practices among adolescents, an age group that has not received much attention. Parents (N = 54, M age = 43.63 years, SD = 6.42; 94.4% female) of adolescents ages 12-17 (N = 54, M age = 13.94 years, SD = 1.75; 43.6% female) completed measures assessing their child feeding practices, eating patterns and the home environment. Adolescents completed measures of their eating patterns. Regression analyses were used to determine the most salient predictors of controlling child feeding practices, specifically restriction of food intake and pressure to eat. After controlling for adolescent age, parental dietary restraint was significantly associated with restriction and accounted for 15.2% of the variance in the use of restriction, F (1, 51) = 10.4, p<.01. Adolescent emotional eating and income-to-needs ratio were significantly associated with use of pressure above and beyond adolescent age and accounted for 29.1% of the variance in the use of pressure, F (2, 48) = 10.2, p<.001. This study suggests that future research should include factors from different levels of influence, such as child, parent and home environment. As understanding of these influences grows, efforts can be made to target specific contributors within intervention settings to address potential adverse outcomes associated with controlling feeding practices.

RESUMEN

Introduction The prevalence of pediatric obesity is an issue in the United States, in which approximately one-third of children and adolescents are overweight or obese. Youth living in low socioeconomic (SES) households are at an increased risk for developing obesity; yet, research is needed to understand the mechanisms that might better explain the relationship between SES and obesity risk. Maternal depression presents a potential mechanism by which SES might predict a later risk for obesity in pediatric populations. Methods The present study used a national dataset from the National Institute of Child Health and Human Development-Study of Early Child Care and Youth Development (NICHD-SECCYD) to examine whether maternal depressive symptoms (at an age of 9 years) mediated the association between early SES (the income-to-needs ratio measured at an age of 1 month) and adolescent weight outcomes [Body Mass Index z-scores (zBMI) for age and sex, at an age of 15 years]. Results The results suggested that greater maternal depressive symptoms helped to explain a significant amount of the variance of lower SES predicting poorer weight outcomes in adolescents. Discussion These findings illustrate the role of maternal depressive symptoms in explaining how SES predicts adolescent weight outcomes. Implications are discussed, and future research is needed to identify women from lower SES households who are experiencing depressive symptoms to provide support and initiate points of early intervention to address relevant health outcomes in youths.

RESUMEN

There are limited criteria for the detection of pulmonary hypertension in dogs undergoing computed tomography (CT) for pulmonary disease. This retrospective analytical exploratory study compared a CT pulmonary trunk to aorta ratio with echocardiographic estimates of pulmonary hypertension. Dogs having both a contrast thoracic CT and echocardiogram were selected and maximal pulmonary trunk and descending aorta diameters were measured by two observers on a single transverse CT image. Computed tomographic diameter ratios were compared with the echocardiographic parameters of tricuspid regurgitation gradient, right ventricular acceleration time-to-ejection time ratio, pulmonary insufficiency gradient, and pulmonary artery to aorta diameter. A total of 78 dogs were sampled, with 44 dogs having one or more finding suggestive of pulmonary hypertension. A moderate positive correlation was shown between tricuspid regurgitation gradient and CT pulmonary trunk to aorta ratio (r = 0.61, P-value < 0.0001). Mean CT pulmonary trunk to aorta ratio of dogs with moderate (P = 0.0132) and severe (P < 0.0003) pulmonary hypertension were significantly higher than normal dogs. There was no significant difference in mean CT pulmonary trunk to aorta ratio between normal and mild pulmonary hypertension dogs (P = 0.4244). The intraclass correlation coefficient (0.72) showed good reproducibility of the ratio. Findings indicated that CT pulmonary trunk to aorta ratio is a reproducible and potentially useful method to predict moderate and severe pulmonary hypertension in dogs, but not mild pulmonary hypertension. In dogs undergoing thoracic CT for pulmonary disease, an increased ratio should prompt follow up echocardiography.

RESUMEN

Fractal analysis of canine pulmonary vessels could allow quantification of their space-filling properties. Aims of this prospective, analytical, cross-sectional study were to describe methods for reconstructing three dimensional pulmonary arterial vascular trees from computed tomographic pulmonary angiogram, applying fractal analyses of these vascular trees in dogs with and without diseases that are known to predispose to thromboembolism, and testing the hypothesis that diseased dogs would have a different fractal dimension than healthy dogs. A total of 34 dogs were sampled. Based on computed tomographic pulmonary angiograms findings, dogs were divided in three groups: diseased with pulmonary thromboembolism (n = 7), diseased but without pulmonary thromboembolism (n = 21), and healthy (n = 6). An observer who was aware of group status created three-dimensional pulmonary artery vascular trees for each dog using a semiautomated segmentation technique. Vascular three-dimensional reconstructions were then evaluated using fractal analysis. Fractal dimensions were analyzed, by group, using analysis of variance and principal component analysis. Fractal dimensions were significantly different among the three groups taken together (P = 0.001), but not between the diseased dogs alone (P = 0.203). The principal component analysis showed a tendency of separation between healthy control and diseased groups, but not between groups of dogs with and without pulmonary thromboembolism. Findings indicated that computed tomographic pulmonary angiogram images can be used to reconstruct three-dimensional pulmonary arterial vascular trees in dogs and that fractal analysis of these three-dimensional vascular trees is a feasible method for quantifying the spatial relationships of pulmonary arteries. These methods could be applied in further research studies on pulmonary and vascular diseases in dogs.

RESUMEN

Disorders of the stifle are a common cause of lameness in horses yet the accuracy of scintigraphy for diagnosis of stifle conditions is controversial. The aim of retrospective cross-sectional study was to determine the diagnostic sensitivity (Se) of bone scintigraphy in detecting stifle disease and to determine if two orthogonal scintigraphic images improve diagnostic Se. Horses that underwent scintigraphic examination during a two-year period were included. Horses were divided into two groups: group 1 (N = 23) had lameness that was localized to the stifle by intra-articular analgesia and group 2 (N = 182) had lameness that was localized to a different location. Scintigraphic studies (one image or two images) were independently and retrospectively analyzed by two radiologists (R1 and R2). Sensitivity, specificity (Sp) and predictive values (PV), and were calculated for each type of study (one image or two images) and for each radiologist (R1 or R2). The Se to detect stifle disorders varied between radiologists (29.2% and 20.8%). The Sp was 84.5% and 88.3%. When two images were evaluated a decrease in the positive PV for both readers occurred. The Cohen kappa coefficient (κ) between readers was poor when one image (0.084) or two images (0.117) were evaluated. Findings from this study indicated that bone-phase nuclear scintigraphy is reasonably specific but highly insensitive for detecting lameness originating from the stifle in a diverse population of both normal and affected horses. The addition of a caudal scintigraphic image acquisition did not improve diagnostic sensitivity.

RESUMEN

BACKGROUND: There is a pressing need to develop effective and broadly accessible interventions to address pediatric obesity. An important dimension in translating interventions to community settings is evaluating the fidelity with which the intended treatment is delivered and the level of facilitator needed to deliver the intervention with efficacy. PURPOSE: The primary objectives of this study were to: 1) provide descriptive information regarding adherence to protocol and non-specific facilitator characteristics (e.g. interpersonal characteristics, group management skills) within the context of a community based pediatric weight control intervention delivered by paraprofessionals; and 2) examine the relationships among facilitator adherence and characteristics and rate of change in percent overweight demonstrated by youth over the course of the 24-week intervention. METHODS: The intervention was conducted between February and September of 2011. Children (6-16 years) and parents completed primary outcome measures at baseline, 12, and 24 weeks (i.e. end of treatment). A 2-part rating form was developed to assess facilitator adherence to weekly content and general provider characteristics at two different time points during the intervention. RESULTS: Youth participating in this study were on average 11.3 years old (SD = 2.8), with most being under the age of 13 years (74.2%). Over half were female (54.8%) and over two-thirds were White (68.4%). On average, facilitators adhered to 96.0% (SD = 5.2%) of the session content at Time 1 and 92.6% (SD = 6.8%) at Time 2. Higher Content Adherence at Time 1 and Time 2 were associated with greater loss in percent overweight. CONCLUSIONS: Our data suggest that paraprofessionals without prior expertise in pediatric weight control can be trained to successfully deliver an intervention that is evidence based and incorporates behavioral and educational components. These findings need to be considered in light of some limitations, including the fact that facilitator domains were assessed with a modification of a standardized tool and we did not obtain inter-rater reliability of observations. These limitations not withstanding, investing time in training facilitators to adhere to a given protocol is critical and may be of higher priority than focusing on more general facilitator characteristics.

RESUMEN

OBJECTIVE: To examine longitudinal bidirectional associations between changes in adolescents' weight status and psychosocial constructs. METHOD: 118 obese adolescents aged 13-16 years participated in a behavioral weight control intervention. Percent overweight (OW), fear of negative evaluation (FNE), and frequency of weight-related teasing (WRT) were collected at baseline, end of intervention, and 12 and 24 months post-randomization. 3 multivariate latent change score models were estimated to examine longitudinal cross-lagged associations between: (1) OW and FNE; (2) OW and WRT; and (3) FNE and WRT. RESULTS: Decreases in OW were prospectively associated with subsequent decreases in both FNE and WRT; however, changes in FNE and WRT were not prospectively associated with subsequent change in OW. Decreases in FNE were prospectively associated with subsequent decreases in WRT. CONCLUSION: Moderate weight loss in the context of a behavioral weight control intervention has positive long-term implications for obese adolescents' peer relations.

RESUMEN

Food insecurity is associated with a multitude of negative outcomes among adolescents. Despite adolescents' burgeoning autonomy, much of the research has relied on parent-proxy report, with few studies directly comparing adolescents' and parents' perceptions of adolescent food security. In the present study, parent-adolescent dyads (N = 144) completed questionnaires measuring perceptions of adolescent food security. Adolescents (12-17 years) completed the Child Food Security Survey Module. Parents completed the Household Food Security Survey Module. Dyads demonstrated discordant perceptions of adolescent food security on categorical- and item-levels of analysis. Further research is needed to elucidate explanations for these discrepancies using longitudinal designs.

RESUMEN

OBJECTIVE: The aim of this study was to estimate the prevalence of food insecurity among children with overweight/obesity presenting for weight management treatment and examine whether food insecurity predicts early change in body mass index (BMI), expressed as a percentage of the 95th percentile (%BMIp95). METHOD: Children (N = 69; ages 3-18 years) presenting to a hospital-based pediatric weight management intervention and 1 parent/guardian per child (N = 69) were included. At the first appointment, parents/guardians completed the US Household Food Security Survey Module: Six-item Short Form and a demographics questionnaire. Height and weight of the children were measured at the first and third appointments to calculate %BMIp95. RESULTS: Among participating families, 29.0% reported experiencing food insecurity. Controlling for the ratio of income to poverty, 11.4% of the variance in %BMIp95 change from the first to third appointments was accounted for by food insecurity, ▵F (1, 66) = 8.46, p = 0.01. Children with greater food insecurity demonstrated a smaller magnitude of %BMIp95 decrease, representing a small-to-medium effect size within the context of the regression model (f2 = 0.13). CONCLUSION: A high proportion of families with children receiving weight management treatment reported experiencing food insecurity in comparison with US households with children. There may be unique characteristics of food insecurity, as opposed to household income alone, that explain the smaller magnitude of BMI decrease observed early in treatment. Future research should explore complex associations among food insecurity, income, BMI, and race over time.

RESUMEN

We present a case of reactive histiocytic disease involving the orbit, optic nerve, retina, and choroid in a Border Collie dog initially presenting for vision loss. Long-term partial return of vision has been achieved with systemic immunosuppression. Anterior segment and ocular surface manifestations of reactive histiocytic disease in dogs are relatively common. Posterior segment and orbital involvement, however, are minimally documented in the existing literature. To the authors' knowledge, this is the first report of disease confined to the orbit and posterior segment as well as the first report of vision loss as a presenting complaint for reactive histiocytic disease. Clinical, magnetic resonance imaging, cytologic, and histopathologic findings are reviewed.

RESUMEN

Disordered eating affects youth from varying socioeconomic backgrounds; however, representation of youth from low-income backgrounds within disordered eating research has been limited. The aim of the current study was to examine the association between adolescent weight and disordered eating among a sample of youth from a low-income background and to examine specific socioenvironmental factors that might moderate this association. Adolescents ages 12-17 (N = 73) from a low-income background and their parents/guardians completed self-report questionnaires. Adolescent height and weight were objectively measured to calculate BMI z-score. Adolescent weight was significantly positively associated with global disordered eating (95 % CI [0.26, 0.54]), after controlling for sex. Parental weight concern moderated the association between weight and global disordered eating, F(4, 68) = 18.44, p < .01, such that the relation between adolescent zBMI and disordered eating was no longer significant at low levels of parental weight concern. Structured family meals moderated the association between weight and global disordered eating, F(4, 68) = 11.99, p < .01, such that more frequent meals weakened the association between adolescent zBMI and disordered eating. Findings suggest that higher weight is associated with greater levels of disordered eating among adolescents from a low-income background. In addition, lower levels of parental weight concern and more frequent family meals significantly buffered the association between weight and disordered eating in this at-risk, yet understudied population. Both parental weight concern and family meals present as factors within the family environment that may serve as targets for intervention.

RESUMEN

OBJECTIVE: Food insecurity has been associated with a variety of adverse outcomes in adolescents. However, further research is needed to elucidate whether adolescent self-report food insecurity contributes to depressive symptoms. This study examined the (1) association between food insecurity and depressive symptoms and (2) moderating role of federal nutrition assistance in a nonclinical sample of adolescents. METHOD: Adolescents aged 12 to 17 years (N = 141) and one parent/guardian completed self-report questionnaires as part of 2 larger studies examining adolescent stress and eating behaviors. Adolescents (M age = 13.79 years, SD = 1.60, 53.9% female) completed measures of food insecurity and depressive symptoms. RESULTS: A bootstrapped linear regression model demonstrated that adolescent food insecurity was significantly, positively associated with depressive symptoms, 95% confidence interval (CI) (0.19-1.64), after controlling for biological sex. Among dyads eligible for federal nutrition assistance (N = 64), the interaction between adolescent food insecurity and National School Lunch Program (NSLP) participation did not reach significance, ΔF(1, 59) = 1.06, 95% CI (-3.80 to 9.29). The interaction between adolescent food insecurity and Supplemental Nutrition Assistance Program (SNAP) participation trended toward significance, ΔF(1, 59) = 2.88, 95% CI (-5.73 to 0.47). CONCLUSION: Adolescents with food insecurity may be at a greater risk for experiencing elevated depressive symptoms. Whereas NSLP participation did not act as a buffer, SNAP participation may attenuate the association between food insecurity and depressive symptoms. Larger longitudinal studies are needed to develop a greater understanding of factors that may alter the relationship between adolescent food insecurity and depressive symptoms.

RESUMEN

A range of barriers may negatively impact adolescents' ability to successfully alter or sustain healthy weight-related behaviors. However, there is a lack of validated measures to empirically assess these barriers. This study developed a measure of adolescent-reported barriers to healthy weight-related behaviors by adapting the previously validated parent-report Barriers to Child Weight Management. Adolescents (N = 154) ages 11-17 presenting to a tertiary weight management program completed Barriers to Weight Management in Adolescence (BWMA). This measure assessed adolescents' perspectives of barriers to healthy weight-related behaviors. Confirmatory factor analysis was used to examine model fit, with four hypothesized subscales-Parental Disengagement, Cost, Lack of Family Support, and Adolescent Disengagement. Overall, good model fit was model demonstrated, χ2 (98) = 130.44, p = .02, CFI = .92, RMSEA = .05, SRMR = .06, supporting a four-factor structure. A final 16-item measure demonstrated good initial psychometric properties. As hypothesized, BWMA was significantly associated with general healthy habits [r = -.25, 95% CI(-.46, -.12)] and parent-reported barriers [r = .40, 95% CI (.264, .586)]. This study adapted and tested preliminary validation of a quantitative measure of adolescent-reported barriers to weight-related behaviors. Identification of barriers may prompt providers to adequately assess, and in turn address, factors impeding adolescents' success in modifying eating and physical activity patterns.

RESUMEN

Weight-based victimization (WBV) is associated with poor weight-related outcomes in adolescence. Family support may be one protective factor against the negative impact of WBV. The goal of this study is to examine the moderating effect of family support on the association between WBV and early weight loss for adolescents in a clinical weight management program. Parents of adolescents (N = 78) completed psychosocial measures at baseline. Objective height and weight were measured at baseline and follow-up (Visit 3). The overall model was significant (p = .02), explaining 12.76% of the variance in weight change over the first 2 months of treatment. As hypothesized, there was a significant moderating effect of family support on the association between WBV and weight change (p = .04), accounting 5.0% of the variance in weight change. Increased support from the family buffered the negative impact of WBV on early treatment outcomes for adolescents in a weight management program.

RESUMEN

OBJECTIVE: The present study sought to extend our understanding of food insecurity among college students, including aims to replicate the high prevalence of food insecurity among college student samples, examine the food insecurity - emotional eating association, and determine whether biological sex moderates this association. PARTICIPANTS: Participants included 232 students (82.3% female; 83.2% Caucasian) enrolled at a U.S. university. METHODS: Participants completed the Household Food Security Survey Module: Short Form and Emotional Eating Scale as part of a larger study. RESULTS: Of the participants, 37.5% reported food insecurity. Food insecurity was positively associated with emotional eating (B = 1.35, 95% CI[0.24, 2.48]), controlling for body mass index (BMI). The association was stronger for males (95% CI[1.07, 6.54]) than females (95% CI[-0.29, 2.07]). CONCLUSIONS: College students, particularly males, who experience food insecurity may be at greater risk for emotional eating. Future research should investigate risk factors linked to both food insecurity and emotional eating among college students.

RESUMEN

A growing body of research suggests disinhibited eating and weaker executive function (EF) are two risk factors for pediatric obesity. Emerging brain imaging and behavioral findings support the notion that EF skills impact eating regulation. However, a major gap in the current literature is a synthesis of the association between various EF skills and disinhibited eating patterns across child development. To address this gap, a systematic review and meta-analysis was conducted to examine the effect of EF skills on disinhibited eating behaviors among youth ages 3-18 years old. PubMed and PsychINFO databases were utilized and data from 15 studies with a total sample of 4909 youth were included. A random effects meta-analysis revealed a small negative effect of overall EF skills on disinhibited eating behavior, r = -0.14, p < 0.01. Analysis of individual EF skills found working memory had an overall medium negative effect on disinhibited eating behavior, r = -0.25, p < 0.05. Taken together, findings from this meta-analysis support an inverse relationship between EF abilities and disinhibited eating patterns in children and adolescents, such that poorer EF abilities are associated with higher levels of disinhibited eating. Given the effect on eating behavior, future research is needed to assess whether EF difficulties may be a barrier to effective weight management in youth. Specifically, research is needed to examine whether EF skills may be a key target to consider for effective obesity prevention and treatment in children and adolescents.
