Emotional dysregulation moderates the relation between perceived stress and emotional eating in adolescent military dependents. Int J Eat Disord 2024. [PMID: 38600832 DOI: 10.1002/eat.24217] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Revised: 03/29/2024] [Accepted: 03/30/2024] [Indexed: 04/12/2024]
Abstract
OBJECTIVE Adolescent children of US service members (i.e., military-dependent youth) face unique stressors that increase risk for various forms of disinhibited eating, including emotional eating. Difficulties with adaptively responding to stress and aversive emotions may play an important role in emotional eating. This study examined emotion dysregulation as a potential moderator of the association between perceived stress and emotional eating in adolescent military dependents. METHOD Participants were military-dependent youth (N = 163, 57.7% female, Mage = 14.5 ± 1.6, MBMI-z = 1.9 ± 0.4) at risk for adult binge-eating disorder and high weight enrolled in a randomized controlled prevention trial. Prior to intervention, participants completed questionnaires assessing perceived stress and emotional eating. Parents completed a questionnaire assessing their adolescent's emotion dysregulation. Moderation analyses were conducted using the PROCESS macro in SPSS and adjusted for theoretically relevant sociodemographic covariates. RESULTS The interaction between adolescent perceived stress and emotion dysregulation (parent-reported about the adolescent) in relation to adolescent emotional eating was found to be significant, such that higher emotion dysregulation magnified the association between perceived stress and emotional eating (p = .010). Examination of simple slopes indicated that associations between perceived stress and emotional eating were strongest for youth with above-average emotion dysregulation, and non-significant for youth with average or below-average emotion dysregulation. DISCUSSION Findings suggest that greater emotion dysregulation may increase risk for emotional eating in response to stress among military-dependent youth at risk for binge-eating disorder or high weight. Improving emotion regulation skills may be a useful target for eating disorder prevention among youth who are at risk for emotional eating. PUBLIC SIGNIFICANCE Prior research has shown that adolescent military dependents are at increased risk for eating disorders and high weight. The current study found that emotion dysregulation moderated the relationship between perceived stress and emotional eating among military-dependent youth. There may be clinical utility in intervening on emotion regulation for adolescent dependents at particular risk for emotional eating and subsequent eating disorders.

Abstract
Intravenous β-lactam antibiotics remain a cornerstone in the management of bacterial infections due to their broad spectrum of activity and excellent tolerability. β-lactams are well established to display time-dependent bactericidal activity, where reductions in bacterial burden are directly associated with the time that free drug concentrations remain above the minimum inhibitory concentration (MIC) of the pathogen during the dosing interval. In an effort to take advantage of these bactericidal characteristics, prolonged (extended and continuous) infusions (PIs) can be applied during the administration of intravenous β-lactams to increase time above the MIC. PI dosing regimens have been implemented worldwide, but implementation is inconsistent. We report consensus therapeutic recommendations for the use of PI β-lactams developed by an expert international panel with representation from clinical pharmacy and medicine. This consensus guideline provides recommendations regarding pharmacokinetic and pharmacodynamic targets, therapeutic drug-monitoring considerations, and the use of PI β-lactam therapy in the following patient populations: severely ill and nonseverely ill adult patients, pediatric patients, and obese patients.

Associations among alexithymia, disordered eating, and depressive symptoms in treatment-seeking adolescent military dependents at risk for adult binge-eating disorder and obesity. Eat Weight Disord 2022; 27:3083-3093. [PMID: 35852767 PMCID: PMC9805474 DOI: 10.1007/s40519-022-01429-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2022] [Accepted: 05/31/2022] [Indexed: 01/04/2023] Open
Abstract
PURPOSE Evidence suggests that difficulties identifying and describing one's feelings, core components of alexithymia, are associated with attitudinal and behavioral symptoms of disordered eating; depressive symptoms also may underlie these associations. Specifically, research indicates that alexithymia is positively related to depressive symptoms, which in turn may promote both disordered-eating attitudes and certain disinhibited-eating behaviors (e.g., emotional eating). Findings also suggest that military-dependent youth with high weight may exhibit elevated depressive symptoms and disordered eating. As such, understanding associations among alexithymia, depressive symptoms, and disordered eating is particularly relevant for this vulnerable population. METHODS We examined 149 adolescent military dependents (14.4 ± 1.6y; 55.0% female; 20.0% non-Hispanic Black; BMIz: 1.9 ± 0.4) at high risk for binge-eating disorder and obesity in adulthood. Participants completed questionnaires assessing two components of alexithymia (difficulty identifying feelings [DIF] and difficulty describing feelings [DDF]), depressive symptoms, emotional eating, and trait anxiety; disordered-eating attitudes were assessed via semi-structured interview. RESULTS A series of regression-based models examined indirect relationships of DIF and DDF with disordered-eating attitudes and emotional eating through depressive symptoms. Bootstrapped 95% confidence intervals revealed a significant indirect path from each of the alexithymia components to disordered-eating attitudes via depressive symptoms; indirect paths to emotional eating were non-significant. CONCLUSION Results support the salience of depressive symptoms in the relationship between alexithymia and disordered-eating attitudes. Future research should utilize prospective designs and explore direct and indirect associations of alexithymia with other disordered-eating behaviors. LEVEL OF EVIDENCE Level III, evidence obtained from a well-designed cohort study.

Examination of the Interaction between Parental Military-Status and Race among Non-Hispanic Black and Non-Hispanic White Adolescents with Overweight/Obesity. J Pediatr Psychol 2022; 47:743-753. [PMID: 35238941 PMCID: PMC9297095 DOI: 10.1093/jpepsy/jsac008] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/18/2021] [Revised: 01/27/2022] [Accepted: 01/31/2022] [Indexed: 12/14/2022] Open
Abstract
OBJECTIVES Adolescent military-dependents experience distinct risk and protective factors, which may necessitate additional clinical considerations. In civilian youth, overweight/obesity is associated with eating, internalizing, and externalizing difficulties, with some studies reporting more difficulties among non-Hispanic White (vs. non-Hispanic Black) youth. It is unknown if these disparities exist among adolescent military-dependents, or between civilian and military-dependent youth. METHODS Non-Hispanic Black (187 civilian, 38 military-dependent) and non-Hispanic White (205 civilian, 84 military-dependent) adolescents with overweight/obesity (14.7 ± 1.6 years; 73.9% girls; body mass index adjusted for age and sex 1.9 ± 0.5) completed a disordered-eating interview; parents completed a measure assessing their child's internalizing and externalizing difficulties. Multiple linear regressions examined parental military-status as a moderator of the relationship of participant race with eating, internalizing, and externalizing difficulties. RESULTS White civilian youth with overweight/obesity reported significantly greater disordered-eating than their Black peers (p < .001); there were no other significant racial differences. In all regressions, parental military-status significantly moderated the association between race and each dependent variable (ps < .047). Black military-dependents (vs. civilians) reported more disordered-eating and internalizing difficulties (ps = .01). White military-dependents (vs. civilians) reported fewer externalizing difficulties (p = .01). CONCLUSIONS Black adolescent military-dependents with overweight/obesity may experience more eating and internalizing difficulties (vs. civilians), a pattern not observed among White participants. Future work should examine if being a military-dependent and a historically marginalized racial group member accounts for these findings. Such data may inform providers of youth with intersecting minority identities.

The Relationship Between Anxiety, Coping, and Disordered-Eating Attitudes in Adolescent Military-Dependents at High-Risk for Excess Weight Gain. MILITARY PSYCHOLOGY 2022; 35:95-106. [PMID: 36968637 PMCID: PMC10012895 DOI: 10.1080/08995605.2022.2083448] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2021] [Accepted: 05/23/2022] [Indexed: 10/18/2022]
Abstract
Adolescent military-dependents are an understudied population who face unique stressors due to their parents' careers. Research suggests that adolescent military-dependents report more anxiety and disordered-eating than their civilian counterparts. While anxiety symptoms predict the onset and worsening of disordered-eating attitudes, the mechanisms underlying this relationship remain unclear. One factor that may underlie this relationship, and be particularly relevant for military-dependent youth, is coping. Therefore, we examined adolescent military-dependents (N=136; 14.5±1.5 years; 59.6% female; BMI-z: 1.9±0.4) who were at-risk for adult obesity and binge-eating disorder due to an age- and sex-adjusted BMI ≥ 85th percentile and loss-of-control eating and/or elevated anxiety. Participants completed an interview assessing disordered-eating attitudes and questionnaires on anxiety symptoms and coping strategies at a single time point. Bootstrapping models were conducted to examine the indirect paths between anxiety symptoms and disordered-eating attitudes through five coping subscales (aggression, distraction, endurance, self-distraction, and stress-recognition). Adjusting for relevant covariates, no significant indirect paths through the coping subscales (ps > .05) were found in any models. General coping, non-specific to eating, may not be a pathway between anxiety symptoms and disordered-eating attitudes among adolescents. Future research should examine other potential mediators of this relationship.

Abstract
Background: Among adults, weight stigma is associated with markers of poor cardiometabolic health. Although weight-based teasing (WBT) is common among youth with high body weight, few studies have examined its associations with cardiometabolic markers. Owing to unique stressors (e.g., parental deployment and frequent moves), military-dependent youth may be at particularly high risk for obesity, WBT, and poor cardiometabolic health. We, therefore, assessed associations between WBT and cardiometabolic health markers among adolescent military dependents presenting for a weight gain prevention trial. Methods: Participants underwent fasting phlebotomy; had fasting weight, height, and waist circumference measured; and completed assessments of WBT, anxiety, and loss-of-control eating. Multivariate analysis of covariance, adjusting for relevant covariates including demographics and body composition, was used to examine differences in metabolic syndrome (MetS) components (waist circumference, systolic and diastolic blood pressure, high-density lipoprotein cholesterol, triglycerides, and glucose) between youth reporting WBT and youth reporting no WBT. Bootstrapped models examined whether WBT mediated the relationship between BMIz and MetS components. Results: Data from 142 youth (57.7% female; 14.4 ± 1.6 years; 51.2% non-Hispanic White, 20.9% non-Hispanic Black; BMIz: 1.9 ± 0.4) were analyzed. WBT was not significantly associated with any MetS component. Relationships were observed between BMIz and all MetS components (except systolic blood pressure and glucose), although WBT did not significantly mediate these relationships (p's > 0.05). Conclusions: This study did not find support for a relationship between WBT and MetS components in adolescent military dependents at risk for adult obesity. Prospective research is needed to determine whether associations between WBT and adverse cardiometabolic outcomes emerge primarily in adulthood.

A Pilot Feasibility Study of Interpersonal Psychotherapy for the Prevention of Excess Weight Gain Among Adolescent Military-dependent Girls. Mil Med 2021; 186:344-350. [PMID: 33241297 PMCID: PMC7909453 DOI: 10.1093/milmed/usaa514] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2020] [Revised: 11/04/2020] [Accepted: 11/09/2020] [Indexed: 11/14/2022] Open
Abstract
INTRODUCTION Adolescent military-dependents face unique psychosocial stressors due to their parents' careers, suggesting they may be particularly vulnerable to excess weight gain and symptoms of depression and anxiety. Despite these risk factors, there is a lack of tested preventative interventions for these youths. Given the transient nature of military family deployments, research may be hindered due to difficulty in collecting long-term prospective outcome data, particularly measured height and weight. The primary aim of this study was to examine the feasibility and acceptability of collecting body mass index (BMI, kg/m2) outcome data up to 2 years following a randomized controlled pilot trial of an adapted interpersonal psychotherapy (IPT) program aimed at preventing excess weight gain and improving psychological functioning for adolescent military-dependents. In exploratory analyses, patterns in body composition over time were examined. MATERIALS AND METHODS Twenty-seven adolescent military-dependent girls (baseline: Mage: 14.4 ± 1.6 years; MBMI: 30.7 ± 4.9 kg/m2; MBMI-z: 1.9 ± 0.4) participated in this study. After a baseline assessment, utilizing a computerized program to create a randomization string, girls were assigned to either an IPT or a health education (HE) program. Participants completed three follow-up visits (posttreatment, 1-year follow-up, and 2-year follow-up). Girls completed a Treatment Acceptability Questionnaire at posttreatment; at all time points, height and fasting weight were collected. For the primary aim, Fisher's exact tests examined the rate of obtained follow-up data and lost to follow-up status between the two groups, Mann-Whitney U tests examined the session attendance between groups, and treatment acceptability ratings were compared between the two groups at posttreatment using an independent samples t-test. For the exploratory aim, one-way analyses of covariance (ANCOVAs) examined the group differences in BMI at each time point, adjusting for baseline values, and paired samples t-tests examined the within-group differences at each time point relative to baseline. Using imputed data in the full intent-to-treat sample, mixed model ANCOVAs were conducted to examine the group differences over time. RESULTS Across both groups, girls attended an average of 72.0% of sessions. At least partial data were collected at posttreatment, 1-year follow-up, and 2-year follow-up for 96.3%, 85.2%, and 74.1% of the participants, respectively. There were no significant group differences in follow-up data collection rates, follow-up status, number of sessions attended, or treatment acceptability. BMI-z stabilized across groups, and there were no group differences in BMI-z. In adjusted ANCOVA models with imputed data, no significant group-by-time effects emerged. CONCLUSIONS For this randomized controlled prevention trial, long-term outcome data collection of measured BMI was possible in adolescent military-dependents and IPT was an acceptable and feasible intervention. An adequately powered trial is required to assess the efficacy of this intervention among military-dependents for obesity prevention and improvements in BMI.

Permanent change of station moves and disordered-eating attitudes and behaviors in prevention-seeking adolescent military-dependents. Eat Behav 2021; 40:101470. [PMID: 33373856 PMCID: PMC7906934 DOI: 10.1016/j.eatbeh.2020.101470] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/19/2020] [Revised: 12/10/2020] [Accepted: 12/16/2020] [Indexed: 11/27/2022]
Abstract
OBJECTIVE Military-dependent youth appear to be at greater risk for disordered-eating than their civilian counterparts. Permanent change of station moves (PCS-moves), typically occurring every 2-3 years, are commonly experienced by adolescent military-dependents. However, the links between PCS-moves and disordered-eating in this population have not been explored. We hypothesized that stress arising from PCS-moves may contribute to the development and/or exacerbation of disordered-eating. METHODS One-hundred-forty-nine adolescent military-dependents with overweight or obesity (59.7% female; 46.3% non-Hispanic White; 14.4±1.5 years; BMI-z: 1.9±0.4) completed measures before commencing an adulthood obesity and binge-eating disorder prevention trial for adolescents at-risk for both conditions due to BMI percentile ≥85th and loss-of-control (LOC)-eating and/or elevated anxiety symptoms. Disordered-eating attitudes and LOC-eating were assessed by semi-structured interview, and emotional eating was self-reported. Adjusting for relevant covariates, multiple linear regressions examined the unique association of PCS-move frequency with disordered-eating attitudes and disinhibited-eating behaviors. RESULTS PCS-move frequency was not significantly associated with either LOC-eating frequency (β = 0.09, p = .27) or emotional eating (β = -0.04, p = .62). However, PCS-move frequency was positively associated with disordered-eating attitudes (β = 0.17, p = .04), which appeared to be primarily driven by shape concerns (β = 0.21, p = .01). DISCUSSION Findings indicate that frequency of PCS-moves is related to disordered-eating attitudes, but not behaviors. Longitudinal research is needed to understand if PCS-moves prospectively relate to the onset and/or exacerbation of disordered-eating, and the relevance of disordered-eating attitudes as opposed to disinhibited-eating behaviors.

1575. Predictors of Negative Clinical Outcomes among Patients treated with Meropenem-Vaborbactam for Serious Gram-Negative Bacterial Infections: Impact of Delayed Appropriate Antibiotic Selection. Open Forum Infect Dis 2020.

Abstract
Abstract
Background
Numerous number of studies have found a positive correlation between delayed appropriate antibiotic therapy and negative clinical outcomes (NCO) in Gram-negative bacterial infections (GNBI). The combination of meropenem with vaborbactam (MVB) received Food and Drug Administration approval for the treatment of complicated urinary tract infections and acute pyelonephritis caused by susceptible organisms in August 2017. We sought to determine the impact of delayed appropriate therapy with MVB on NCO among patients with GNBI.
Methods
Multi-center, retrospective cohort study from October 2017 to March 2020. We included adult patients treated with MVB for >72 hours. We excluded patients who received alternative appropriate antibiotics for GNB prior to MVB and patients with unknown dates for index culture. NCO were defined as 30-day mortality and/or microbiological recurrence. All outcomes were measured from MVB start date. Classification and regression tree analysis (CART) was used to identify the time breakpoint (BP) that delineates the risk of NCO. Multivariable logistic regression analysis (MLR) was used to examine the independent association between the CART-derived-BP and NCO. Variables were retained in the model if P< 0.2 and removed in a backward stepwise approach.
Results
A total of 86 patients were included from 13 institutions in the United States: median(IQR) age 55 (37-67) years, 67% male, and 48% Caucasian. Median(IQR) APACHE II and Charlson Comorbidity index scores were 18(11-26) and 4(2-6), respectively. Common sources of infection were respiratory (37%) and intra-abdominal (21%). The most common pathogens were carbapenem-resistant Enterobacterales (83%). CART-derived BP between early and delayed treatment was 48 hours, where NCO was increased (36% vs.7%; P=0.04). Delayed MVB initiation was independently associated with NCO in the MLR (aOR=7.4, P=0.02).
Results of Regression Analysis of Variables Associated With Negative Clinical Outcomes and Delayed Appropriate Therapy with Meropenem-vaborbactam
Conclusion
Our results suggest that delaying appropriate antibiotic therapy with MVB for >48 hours significantly increases the risk of NCO in patients with GNBI. Clinicians must ensure timely administration of MVB to assure best outcomes in patients with GNBI.

Abstract
BACKGROUND Metabolic syndrome in adolescence has been associated with adverse cardiometabolic outcomes in adulthood. Preliminary data suggest that boys may have worsened metabolic syndrome components compared to girls. Yet, little is known about the physical health of military dependents, a potentially at-risk population. OBJECTIVE Examine sex differences in metabolic syndrome components in a sample of adolescent military dependents. METHODS Participants were adolescents (N = 139; 14.4 ± 1.6 years; 45.3% male; 41.0% non-Hispanic White, 19.4% non-Hispanic Black; BMI-z: 1.9 ± 0.4) at-risk for adult obesity and binge-eating disorder due to an age- and sex-adjusted BMI ≥85th percentile and loss-of-control eating and/or elevated anxiety. A multivariate analysis of covariance was conducted to compare objectively measured metabolic syndrome components across boys and girls. Covariates were age, race, loss-of-control eating status, anxiety symptoms, and BMI-z. RESULTS Metabolic syndrome components differed by sex (P = .01). Boys had higher systolic blood pressure (P = .049), lower high-density lipoprotein cholesterol (P = .01), and higher glucose (P = .001) than girls. Waist circumference, diastolic blood pressure, and triglycerides did not differ between boys and girls (P > .05). CONCLUSIONS Future research should prospectively examine these relationships into adulthood. If the current findings are supported, prevention programs should consider targeting cardiometabolic health particularly among male adolescent military dependents.

Abstract
OBJECTIVE Adolescent military dependents may be at higher risk for psychosocial stressors and disordered eating compared with civilian youths, but the mechanisms underlying these risks are unclear. Interpersonal theory proposes that difficult relationships lead to negative affect, thereby promoting emotional eating, which has been linked to and predictive of disordered eating. The interpersonal model may have particular relevance for understanding disordered eating among adolescent military dependents, given the unique stressors related to their parents' careers. This study aimed to examine the premise of the interpersonal model (that negative emotions mediate the association between multiple aspects of social functioning and emotional eating) among a cohort of adolescent military dependents. METHODS Military dependents (N=136; 56% female, mean±SD age=14±2 years, body mass index adjusted for age and sex [BMIz]=2.0±0.4) at risk for adult obesity and binge eating disorder, as indicated by reported loss-of-control eating and/or anxiety symptoms, were assessed prior to participation in a study of excess weight-gain prevention. Bootstrapped mediation analyses were conducted to examine depressive symptoms as a potential mediator of the relationship between social functioning and emotional eating. Analyses were adjusted for age, sex, race-ethnicity, BMIz, and presence of reported loss-of-control eating and anxiety. RESULTS Depressive symptoms were a significant mediator of the relationship between multiple domains of social functioning, including loneliness, social adjustment related to family and friends, attachment to father and peers, and emotional eating (p<0.05). CONCLUSIONS The interpersonal model may contribute to our understanding of excess weight gain and binge eating disorder among adolescent military dependents. Prospective data are needed to determine the utility of interpersonal theory in predicting treatment response and outcomes among this population.

Parental deployment and distress, and adolescent disordered eating in prevention-seeking military dependents. Int J Eat Disord 2020; 53:201-209. [PMID: 31593352 PMCID: PMC7028444 DOI: 10.1002/eat.23180] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/02/2019] [Revised: 09/13/2019] [Accepted: 09/13/2019] [Indexed: 01/23/2023]
Abstract
OBJECTIVE Parental military deployment can lead to stress in the family system due to concerns about the deployed service-member's safety and increased responsibilities for those not deployed. Parent-related stress can impact adolescent disordered eating. Given the important role that stress plays in disordered eating and obesity, it is crucial to understand the impacts of unique stressors to which vulnerable populations are exposed. METHOD We studied 126 adolescent (14.3 ± 1.6 years; 59.5% girls; 44.4% non-Hispanic White; BMI-z, 1.91 ± .39) military dependents prior to entering an obesity and binge-eating disorder prevention trial. The Eating Disorder Examination was used to assess adolescent disordered eating. Parents self-reported their own distress and family deployment history that occurred during the adolescent's lifetime. RESULTS Parental distress interacted with frequency of parental deployments such that for those with high parental distress, more frequent deployment was associated with greater adolescent shape and weight concerns (β = .21, p = .012) and global eating pathology (β = .18, p = .024). DISCUSSION In this hypothesis-generating study, the combination of number of deployments and parental distress may be associated with disordered eating among adolescent military dependents seeking prevention of binge-eating disorder and adult obesity. If these preliminary findings are supported longitudinally, interventions to reduce parental stress related to deployment may be warranted to reduce disordered eating in adolescent dependents.

Associations between Family Weight-Based Teasing, Eating Pathology, and Psychosocial Functioning among Adolescent Military Dependents. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 17:ijerph17010024. [PMID: 31861426 PMCID: PMC6982056 DOI: 10.3390/ijerph17010024] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/13/2019] [Revised: 12/13/2019] [Accepted: 12/15/2019] [Indexed: 01/25/2023]
Abstract
Weight-based teasing (WBT) by family members is commonly reported among youth and is associated with eating and mood-related psychopathology. Military dependents may be particularly vulnerable to family WBT and its sequelae due to factors associated with their parents’ careers, such as weight and fitness standards and an emphasis on maintaining one’s military appearance; however, no studies to date have examined family WBT and its associations within this population. Therefore, adolescent military dependents at-risk for adult obesity and binge-eating disorder were studied prior to entry in a weight gain prevention trial. Youth completed items from the Weight-Based Victimization Scale (to assess WBT by parents and/or siblings) and measures of psychosocial functioning, including the Beck Depression Inventory-II, The Rosenberg Self-Esteem Scale, and the Social Adjustment Scale. Eating pathology was assessed via the Eating Disorder Examination interview, and height and fasting weight were measured to calculate BMIz. Analyses of covariance, adjusting for relevant covariates including BMIz, were conducted to assess relationships between family WBT, eating pathology, and psychosocial functioning. Participants were 128 adolescent military dependents (mean age: 14.35 years old, 54% female, 42% non-Hispanic White, mean BMIz: 1.95). Nearly half the sample (47.7%) reported family WBT. Adjusting for covariates, including BMIz, family WBT was associated with greater eating pathology, poorer social functioning and self-esteem, and more depressive symptoms (ps ≤ 0.02). Among military dependents with overweight and obesity, family WBT is prevalent and may be linked with eating pathology and impaired psychosocial functioning; prospective research is needed to elucidate the temporal nature of these associations.

Abstract
Stressors unique to military families may place dependents of military service members of both sexes at high-risk for disordered-eating. Yet, there are no data examining sex-related differences in eating pathology and distress among this population. Therefore, we examined disordered-eating attitudes and associated psychosocial characteristics in adolescent military dependents at high-risk for both eating disorders and adult obesity (i.e., BMI ≥ 85th percentile and elevated anxiety symptoms and/or loss-of-control eating). One-hundred-twenty-five (55.2% female) adolescent (12-17 y) military dependents were studied prior to entry in an eating disorder and obesity prevention trial. Youth were administered the Eating Disorder Examination interview to determine disordered-eating attitudes, and completed questionnaires to assess self-esteem, social functioning, and depression. Girls and boys did not differ in BMIz (p = .66) or race/ethnicity (p = .997/p = .55). Adjusting for relevant covariates, girls and boys did not differ significantly with regard to disordered-eating global scores (p = .38), self-esteem (p = .23), or social functioning (p = .19). By contrast, girls reported significantly more symptoms of depression (p = .001). Adolescent male and female dependents at high-risk for eating disorders and adult obesity reported comparable levels of eating-related and psychosocial stress. Data are needed to elucidate how adolescent military dependents respond to intervention and whether sex moderates outcome.

Abstract
Background Vancomycin (VAN) is the primary agent for the treatment methicillin-resistant Staphylococcus aureus (MRSA) bloodstream infections (BSI). VAN is frequently combined with or switched to a second anti-MRSA agent for the treatment of serious BSI because VAN monotherapy has been linked to treatment failures. We aimed to determine the potential risk factors for patients with MRSA BSI who switched or had therapy escalated. Methods This was a multicenter, retrospective cohort study of adults (≥18 years) initially treated with VAN (>24 hours) for MRSA BSI between 2006 and 2018. Patients with a respiratory source were excluded. Baseline clinical and infection characteristics were compared between patients who received VAN as the sole anti-MRSA agent and continued on VAN until discharge and patients who switched or had a second anti-MRSA agent added during their admission (switch/escalate group). Multivariable logistic regression was performed to identify independent predictors of therapy switch or escalation. Results A total of 195 patients were included (66 VAN and 129 switch/escalate). The mean (SD) age of the study population was 56 (15.5) years, 68.2% were male, and 81.0% were African-American. Most (80%) of patient had community-onset BSI. The median (IQR) Charlson Comorbidity index and Acute Physiology and Chronic Health Evaluation (APACHE) II scores were 3 (1–5) and 14 (8–20), respectively. The major sources of BSI were skin/soft tissue (24.6%), infective endocarditis (24.1%), and bone/joint (23.1%). Median (IQR) time to switch/escalation was 67 (44–97) hours. In multivariable logistic regression analysis, infective endocarditis (aOR 6.2, 95% CI 2.2–16), hospitalization in the past 90 days (aOR 2.0, 95% CI 1.0–4.0), and APACHE II (aOR 1.07, 95% CI 1.01–1.12) were independently associated with switch/escalation. Conclusion We have identified a number of baseline clinical and infection characteristics that should be taken into account for clinicians to predict the likelihood of switch or escalation in vancomycin treated patients with MRSA BSI. Further studies evaluating the impact of up front alternative therapies in these higher risk patients are needed. Disclosures S. L. Davis, Achaogen: Scientific Advisor, Consulting fee.

Abstract
Background Methicillin-resistant Staphylococcus aureus bloodstream infection (MRSA BSI) is associated with high morbidity and mortality. The prediction of outcomes may have a profound impact on clinical decision making and risk stratification. The Acute Physiology and Chronic Health Evaluation (APACHE) II Score and the Pitt Bacteremia Score (PBS) have been repeatedly described as independent predictors of mortality in MRSA BSI. The APACHE II is complex to calculate and many of the variables may not be pertinent to MRSA BSI. The PBS is a simple score using readily assessable variables. The comparative predictive performance of the two models in MRSA BSI has not been evaluated. Methods Retrospective, observational, singe-center cohort study in adults with MRSA BSI between 2008 and 2018. Patients who did not receive active therapy ≤72 hours of index culture were excluded. APACHE II and PBS were calculated using the worst physiological values recorded ≤24 hours of blood culture collection. Discriminatory ability for 30-day mortality was assessed using the c-statistic and was compared using the Hanley and McNeil method. The best cut-off point in each scoring system was determined using the Youden Index (J). Results A total of 455 patients were included. The median (IQR) PBS and APACHE II were 2 (0, 3) and 18 (11, 23), respectively. All-cause 30-day mortality was 16.3%. The c-statistic (95% CI) for the APACHE II vs. PBS in the overall cohort and stratified by ICU status were: 0.813 (0.763, 0.863) vs. 0.717 (0.653, 0.782), P = 0.0035; ICU 0.729 (0.610, 0.848) vs. 0.570 (0.442, 0.699), P = 0.026; and non-ICU 0.821 (0.761, 0.881) vs. 0.700 (0.614, 0.786),P = 0.0046, respectively. The APACHE II with the maximum J value was 21; sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) for 30-day mortality were 81.08%, 72.97%, 36.81%, and 95.21%, respectively. The PBS with the maximum J value was 3; sensitivity, specificity, PPV, and NPV were 66.22%, 72.18%, 31.61%, and 91.67%, respectively. Conclusion The APACHE II was superior to the PBS in predicting 30-mortality in patients with MRSA BSI in the overall cohort and stratified by ICU status at BSI onset. Future research to develop a more practical scoring model with high discriminatory power is needed. Disclosures M. J.

Abstract
Abstract
Background
Methicillin-resistant Staphylococcus aureus bloodstream infection (MRSA BSI) is associated with high mortality despite advances in medical care. Mortality prediction may have a profound impact on clinical decision making and risk stratification. Widely used scoring systems such as the Acute Physiology and Chronic Health Evaluation (APACHE) II Score and the Pitt Bacteremia Score were derived in the general critical care and Gram-negative BSI populations, respectively and may be less precise in MRSA BSI. We sought to develop a predictive model (PM) for 30-day mortality in patients with MRSA BSI based on characteristics readily assessable at initial evaluation.
Methods
Retrospective, singe-center, cohort study in adults with MRSA BSI 2008 to 2018. Patients who did not receive active therapy within 72 hours of index culture were excluded. Independent baseline demographic, clinical and infection predictors of 30-day mortality were identified through multivariable logistic regression analysis with bootstrap resampling and coefficient shrinkage. The PM was derived using a regression coefficient-based scoring method. PM discriminatory ability was assessed using the c-statistic. The optimal threshold score was determined using the Youden Index (J).
Results
A total of 455 patients were included and 30-day mortality was 16.3%. The PM consisted of five variables and a potential total score of 33. Points were assigned as follows: age (9 points ≥90 years, 6 points 80–89 years, 5 points 70–79 years, 0 points <70 years); Glasgow Coma Scale (8 points ≤9, 5 points 10–13, 0 points ≥14); 7 points infective endocarditis or pneumonia; 5 points serum creatinine ≥ 3.5 dl/L; and four points respiratory rate <10 or >24. The PM c-statistic was 0.860 (95% CI 0.818, 0.902). The PM score with the maximum J value was 13. Thirty-day mortality was 5.2% vs. 44.5% for PM score <13 vs. ≥13 points, respectively (P < 0.001). The sensitivity, specificity, positive predictive value (PV), negative PV, and accuracy using a threshold of 13 points were 77.0%, 81.4%, 44.5%, 94.8%, and 80.7%, respectively.
Conclusion
Our findings demonstrate a weighted combination of five independent variables readily assessable at initial evaluation can be used to predict, with high discrimination, 30-d mortality in MRSA BSI. External validation is required before wide-spread clinical use.

Abstract
Background and context: The number of people living with breast cancer and beyond is increasing. The nurse led clinics prioritise the patient as the center of care, providing the opportunity to address the serious medical, functional and psychosocial consequences of cancer and its treatments. Aim: To evaluate a model of survivorship care from the patient´s perspective. Strategy/Tactics: Eligible patients were identified through the multidisciplinary team breast meeting. Consultation with the breast care nurse at approximately 10 months postdiagnosis. Prior to this appointment, validated screening tools were sent to attendees and completed. Through assessment and discussion, issues were identified and addressed, with onward referral to internal and community based organizations. Resource packs provided together with a care plan. Program/Policy process: Having offered the nurse led clinics for 18 months Western Health conducted a patient satisfaction survey. Data were collected in the form of a questionnaire to ascertain the effect of the clinic in providing optimal and supportive survivorship care. Outcomes: 208 patients seen, 134 were born in a country other than Australia. 208 surveys sent to both English and non-English speaking patients. 91 respondents. 72% made changes to their lifestyles and relationships following the nurse led clinic. 93% of respondents felt they had more time to talk about their concerns and ask questions. 92% felt the BCN provided helpful information about support services and programs that they would otherwise not be aware of. What was learned: Patients may experience significant burden of symptoms following definitive treatment of early breast cancer. The nurse led clinic allows patients space to reflect and explore their disease experience to date, which for many has resulted in positive lifestyle changes.

Abstract
Monitoring racehorse fatality and associated jockey falls provides benchmarks for intervention strategies. The aims of this study were to describe the incidence of and reasons for fatalities in Thoroughbred horses during flat races in the Australian Capital Territory and New South Wales (NSW), Australia, and to describe reported jockey falls and injuries associated with racehorse fatalities. A cohort study identified all racehorse fatalities reported through Racing NSW for the 2009-2010 to 2013-2014 racing seasons. Risks of racehorse fatality, fatal musculoskeletal injury, spontaneous death (as distinct from euthanasia) and racehorse fatality associated jockey falls and injuries were calculated using Poisson regression. A total of 167 horse fatalities were reported, with an overall incidence of 0.59 deaths/1000 starts. Forty-nine reasons for horse fatality were reported, although post-mortem examinations were conducted on only 52/165 (31.5%) horses. Musculoskeletal injury accounted for 144/167 (86.2%) fatalities, with an incidence of 0.52/1000 starts. Fractures comprised 96/167 (57.5%) fatalities, with the fetlock or proximal sesamoid bones being the most common fracture location, comprising 36/96 (37.5%) fractures. Only 22/166 (13.3%) racehorse fatalities were due to spontaneous death, representing an incidence of 0.08/1000 starts. A total of 50 racehorse fatality associated jockey falls were reported (incidence of 0.18/1000 starts), with 32 reported jockey injuries (incidence of 0.12/1000 starts). Most racehorse fatality associated jockey injuries occurred to the limbs (17/32, 53.1%), particularly the upper limb. The estimates for both horse fatality and associated jockey injury were comparable with previous estimates from other jurisdictions internationally.

Abstract
BACKGROUND Optimal management of urinary tract infections (UTIs) in the emergency department (ED) is challenging due to high patient turnover, decreased continuity of care, and treatment decisions made in the absence of microbiologic data. We sought to identify risk factors for return visits in ED patients treated for UTI. METHODS A random sample of 350 adult ED patients with UTI by ICD 9/10 codes was selected for review. Relevant data was extracted from medical charts and compared between patients with and without ED return visits within 30days (ERVs). RESULTS We identified 51 patients (15%) with 59 ERVs, of whom 6% returned within 72h. Nearly half of ERVs (47%) were UTI-related and 33% of ERV patients required hospitalization. ERVs were significantly more likely (P<0.05) in patients with the following: age≥65years; pregnancy; skilled nursing facility residence; dementia; psychiatric disorder; obstructive uropathy; healthcare exposure; temperature≥38 °C heart rate>100; and bacteremia. Escherichia coli was the most common uropathogen (70%) and susceptibility rates to most oral antibiotics were below 80% in both groups except nitrofurantoin (99% susceptible). Cephalexin was the most frequently prescribed antibiotic (51% vs. 44%; P=0.32). Cephalexin bug-drug mismatches were more common in ERV patients (41% vs. 15%; P=0.02). Culture follow-up occurred less frequently in ERV patients (75% vs. 100%; P<0.05). CONCLUSIONS ERV in UTI patients may be minimized by using ED-source specific antibiogram data to guide empiric treatment decisions and by targeting at-risk patients for post-discharge follow-up.

Abstract
BACKGROUND The World Health Organization recommends exclusive breastfeeding until 6 months followed by introduction of iron-rich complementary foods (CFs). The aim of this study was to determine the impact of different iron-rich CFs on infant gut inflammation and microbiota. METHODS Eighty-seven exclusively breastfed infants were randomly assigned to receive one of the following as their first CF: iron-fortified cereal (Cer), iron-fortified cereal with fruit (Cer + Fr), or meat (M). Urine and stool samples were collected to assess reactive oxygen species (ROS) generation, gut microbiota and inflammation. RESULTS Fecal iron differed across feeding groups (p < 0.001); levels were highest in the Cer group and lowest in M group. A significant increase of fecal ROS formation (p < 0.002) after the introduction of CFs was observed, but did not differ across feeding groups. Fecal calprotectin increased within all groups after the introduction of CFs (p = 0.004). Gut microbiota richness increased after introduction of M or Cer + Fr. Regardless of feeding group, Coriobacteriaceae were positively correlated with ROS and Staphylococcaceae were negatively correlated with calprotectin. CONCLUSIONS Choice of first CF may influence gut inflammation and microbiota, potentially due to variations in iron absorption from different foods. Further research is warranted to fully characterize these associations and to establish implications for infant health. This study was registered in the ClinicalTrial.gov registry (Identifier No. NCT01790542 ). TRIAL REGISTRATION This study was registered in the ClinicalTrial.gov registry under the name "Assessment of Complementary Feeding of Canadian Infants" (Identifier No. NCT01790542 ) February 6, 2013.

Abstract
A high-resolution (HR) data collection mode has been introduced to the whole-body, research photon-counting-detector CT system installed in our laboratory. In this mode, 64 rows of 0.45 mm × 0.45 mm detectors pixels were used, which corresponded to a pixel size of 0.225 mm × 0.225 mm at the iso-center. Spatial resolution of this HR mode was quantified by measuring the MTF from a scan of a 50 micron wire phantom. An anthropomorphic lung phantom, cadaveric swine lung, temporal bone and heart specimens were scanned using the HR mode, and image quality was subjectively assessed by two experienced radiologists. Comparison of the HR mode images against their energy integrating system (EID) equivalents using comb filters was also performed. High spatial resolution of the HR mode was evidenced by the MTF measurement, with 15 lp/cm and 20 lp/cm at 10% and 2% MTF. Images from anthropomorphic phantom and cadaveric specimens showed clear delineation of small structures, such as lung vessels, lung nodules, temporal bone structures, and coronary arteries. Temporal bone images showed critical anatomy (i.e. stapes superstructure) that was clearly visible in the PCD system but hardly visible with the EID system. These results demonstrated the potential application of this imaging mode in lung, temporal bone, and vascular imaging. Other clinical applications that require high spatial resolution, such as musculoskeletal imaging, may also benefit from this high resolution mode.

Inducing the loss of conditionally dispensable chromosomes in Nectria haematococca during vegetative growth. Curr Genet 1998; 33:299-303.

Abstract
A procedure for inducing and detecting the loss of conditionally dispensable (CD) chromosomes in filamentous fungi during vegetative growth was developed using Nectria haematococca mating population VI as a model. CD chromosomes in two different isolates of N. haematococca were tagged via integrative transformation with a gene conferring resistance to hygromycin B. In each case the transformation vector included chromosome-specific DNA in order to direct its homologous recombination with the desired chromosome. Chromosome loss was induced by exposing tagged isolates to inhibitory concentrations of benomyl either for protracted periods of time on solid medium or for short periods of time in liquid medium. After exposure to benomyl, isolates that lost the tagged chromosome were identified by their loss of resistance to hygromycin B. Electrophoretic karyotyping was used to verify that isolates which failed to grow on hygromycin B lacked an intact CD chromosome. Ten other chemicals known to interfere with mitotic events or cell development in other organisms did not induce CD chromosome loss in N. haematococca.

Abstract
A gene encoding a highly thermostable extracellular alpha-amylase from the hyperthermophilic archaeon Pyrococcus furiosus was identified. The gene was cloned, sequenced, and expressed in Escherichia coli and Bacillus subtilis. The gene is 1383 base pairs long and encodes a protein of 461 amino acids. The open reading frame of the gene was verified by microsequencing of the recombinant purified enzyme. The deduced amino acid sequence is 25 amino acids longer at the N terminus than that determined by sequencing of the purified protein, suggesting that a leader sequence is removed during transport of the enzyme across the membrane. The recombinant alpha-amylase was biochemically characterized and shows an activity optimum at pH 4.5, whereas the optimun temperature for enzymatic activity is close to 100 degrees C. alpha-Amylase shows sequence homology to the other known alpha-amylases and belongs to family 13 of glycosyl hydrolases. This extracellular alpha-amylase is not homologous to the subcellular alpha-amylase previously isolated from the same organism.

Abstract
A fragment from Bacillus acidopullulyticus strain 294-16 encoding a pullulanase activity has been cloned into Bacillus subtilis. The nucleotide sequence of the 3972 base pairs (bp) fragment has been determined and shown to include only one complete open reading frame (ORF) of 863 codons. The deduced amino acid sequence of this ORF, denoted pulB, shows homology to a number of amylolytic enzymes. Primary and secondary structure analysis indicates that the central region of the protein forms the catalytic domain in a characteristic (beta/alpha)8 barrel. Three carboxylic acid residues essential for catalysis were identified. Regions within the catalytic domain proposed to be involved in substrate binding have been identified by homology.

Abstract
Children without an auditory brainstem evoked response can benefit from an auditory-oral hearing habilitation program. This study focuses on 31 such children enrolled at the Houston School for Deaf Children. Eleven had excellent auditory-oral skills, with language ability equal to normal-hearing children of a similar age, and speech easily intelligible to a familiar listener. A statistically significant factor associated with success was hearing acuity at 250 Hz. Other important factors included age at enrollment at the school, duration of enrollment, degree of parental support, and absence of middle ear disease.

Abstract
Model investigations were performed on a canister containing 600 g of Sodasorb indicator soda lime in a transparent lime compartment used in the Hafnia circle. The CO2 input was 300 ml per min. Carbon dioxide will be efficiently eliminated from the gas mixture conveyed to the patient connection in this system for at least 4 h, irrespective of the rate of fresh gas flow. There was proportionality between the fresh gas inflow and the duration of effective CO2 elimination. The relative efficacy of the CO2 absorption was investigated at different levels in the canister. The temperature in the axis of the lime compartment was 43-52 degrees C, and the temperature of the gas mixture conveyed to the patient attachment 30-35 degrees C. The colour shift in the lime charge was a reliable indicator of the efficiency of CO2 elimination. The canister should be replaced when the colour shift has progressed to 2/3 of the lime charge. The canister contains no disposable parts except for the lime charge. All the components of the circle system should be taken apart and cleaned after each anaesthesia.

Abstract
An open reservoir for the collection and evacuation of anaesthetic gases permits leakage to room air. The use of a closed reservior for the removal of overspill gas from anaesthetic circuits is described. Calibrated gas evacuation is carried out through an ejector flowmeter from the anesthetic circuit or from a closed reservoir, where the gas is collected via a relief valve. In order to eliminate the risk of high or low pressure in the reservoir employed, a relief valve and a dumping valve is included in the system.
