"I Haven't Told Anyone but You": Experiences and Biopsychosocial Support Needs of People With Type 2 Diabetes and Binge Eating

Up to 25% of people with type 2 diabetes (T2D) may binge eat which is almost 10 times as many as in the general population. Binge eating is associated with depression, anxiety, and social isolation. Moreover, binge eating may increase the risk of obesity and high blood glucose levels, both of which can accelerate the onset of complications to diabetes and death in people with T2D. Still, little is known about the experiences, needs, and preferences of people with T2D and binge eating that can inform and develop current and future treatment efforts. The aim of the study was therefore to gain in-depth insights into the experiences and biopsychosocial support needs of women and men with T2D and binge eating. Twenty semi-structured individual interviews (65% with females) were conducted and analyzed according to the methodology of Interpretive Description. Four themes were identified: (a) T2D and binge eating: Feeling trapped in a vicious circle; (b) Unwanted outcasts: Responding to continuous criticism; (c) Biomedical relief: Blaming and adjusting the body; and, (d) Silent struggles: Wanting to cease the secrecy. Pertinent to all themes were the guilt, shame, and worries about developing complications that the participants experienced when binge eating despite having T2D. Although binge eating triggered emotional distress, binge eating was at the same time a way of coping with such distress. Implications for treatment and future research are discussed, including the need to systematically assess and address binge eating in routine T2D care.

Switch to Lisdexamfetamine in the Treatment of Attention-Deficit Disorder at a Psychiatric Outpatient Clinic for School-Aged Children: A Danish Cohort Study

Objectives: This study aimed to examine switch from first-line methylphenidate (MPH) to lisdexamfetamine (LDX) in school-aged children with attention-deficit/hyperactivity disorder (ADHD). Methods: This is a retrospective observational study based on systematic review of patient records of all children (7-13 years) diagnosed with ADHD and referred to a Danish specialized outpatient clinic. The study included 394 children switching from MPH to LDX as either second-line or third-line treatment (atomoxetine [ATX] as second-line treatment) during the study period from April 1, 2013, to November 5, 2019. Results: One in five children switched from MPH to LDX at some point during the study period. The most frequent reasons for switching to LDX were adverse effects (AEs; 70.0% for MPH, 68.3% for ATX) and lack of efficiency (52.0% for MPH, 72.7% for ATX). Top five AEs of LDX were decreased appetite (62.4%), insomnia (28.7%), irritability/aggression (26.1%), weight decrease (21.1%), and mood swings (13.9%). MPH and LDX had similar AE profiles, yet most AEs were less frequent after switching to LDX. At the end of the study period, the majority were prescribed LDX as second-line rather than third-line treatment (86.1% in 2019). However, the likelihood of LDX as second-line treatment decreased with the number of psychiatric comorbidities, ADHD symptom severity as assessed by parents, and if AEs were a reason for MPH discontinuation. Among children observed for at least 1 year after initiation of LDX, 41.3% continued LDX treatment for a year or longer. LDX continuation was less likely if AEs were a reason for MPH discontinuation. Similarly to MPH and ATX, the most frequent reasons for LDX discontinuation were AEs (74.4%) and lack of efficiency (34.7%). Implications: The findings support LDX as an important option in the personalized treatment of children with ADHD and may support prescribers in the clinical decision-making on switching medication.

Plasma proteome profiling reveals metabolic and immunologic differences between Anorexia Nervosa subtypes

AIMS/HYPOTHESIS

Anorexia Nervosa (AN) is a severe psychiatric disorder of an unknown etiology with a crude mortality rate of about 5 % per decade, making it one of the deadliest of all psychiatric illnesses. AN is broadly classified into two main subtypes, restricting and binge/purging disorder. Despite extensive research efforts during several decades, the underlying pathophysiology of AN remains poorly understood. In this study, we aimed to identify novel protein biomarkers for AN by performing a proteomics analysis of fasting plasma samples from 78 females with AN (57 restrictive and 21 binge/purge type) and 70 healthy controls.

METHODS

Using state-of-the-art mass spectrometry-based proteomics technology in conjunction with an advanced bioinformatics pipeline, we quantify >500 plasma proteins.

RESULTS

Differential expression analysis and correlation of proteomics data with clinical variables led to identification of a panel of novel protein biomarkers with potential pathophysiological significance for AN. Our findings demonstrate evidence of a humoral immune system response, altered lipid metabolism and potential alteration of plasma cells in AN patients. Additionally, we stratified AN patients based on the quantified proteins and suggest a potential autoimmune nature in the restrictive subtype of AN.

CONCLUSIONS/INTERPRETATION

In summary, on top of biomarkers of AN subtypes, this study provides a comprehensive map of plasma proteins that constitute a resource for further studies of the pathophysiology of AN.

Predicting the impact and duration of persistent and mobile organic compounds in groundwater systems using a contaminant mass discharge approach

This study investigated methods for predicting the duration and impact on groundwater quality from persistent and mobile organic compounds (PMOCs) at a drinking water well field affected by multiple contaminant sources. The fungicide metabolite N,N-dimethylsulfamide (DMS), which frequently occurs above the Danish groundwater quality criterion (0.1 μg/L), was used as an example. By combining contaminant mass discharge (CMD) estimations, modeling, and groundwater dating, a number of important discoveries were made. The current center of contaminant mass was located near the source area. The CMD at the well field was predicted to peak in 2040, and an effect from the investigated sources on groundwater quality could be expected until the end of the 21st century. A discrepancy in the current CMD at the well field and the estimated arrival time from the studied source area suggested an additional pesticide source, which has not yet been thoroughly investigated. The presence of the unknown source was supported by model simulations, producing an improved mass balance after inclusion of a contaminant source closer to the well field. The approach applied here was capable of predicting the duration and impact of DMS contamination at a well field at catchment scale. It furthermore shows potential for identification and quantification of the contribution from individual sources, and is also applicable for other PMOCs. Predicting the duration of the release and impact of contaminant sources on abstraction wells is highly valuable for water resources management and authorities responsible for contaminant risk assessment, remediation, and long-term planning at water utilities.

Fracture Risk in Patients with Anorexia Nervosa Over a 40-Year Period

Researchers have reported increased fracture risk in patients with anorexia nervosa (AN), but more knowledge on the long-term risk and the effects of age, male sex, and time-related changes is still needed. We examined the long-term (up to 40 years) fracture risk among patients with AN compared to a matched comparison cohort from the general population. We utilized data from the Danish Health Care Registers to identify 14,414 patients with AN (13,474 females and 940 males) diagnosed between 1977 and 2018, with a median age of 18.6 years and median follow-up time of 9.65 years. We calculated adjusted hazard ratios (aHRs) with 95% confidence intervals (CIs) using Cox regression analysis for overall and site-specific fracture risks. The overall aHR of any fracture was 1.46 [95% CI: 1.36 to 1.48], with an aHR of 1.50 [95% CI: 1.43 to 1.57] for females and 0.95 [95% CI: 0.82 to 1.1] for males. For specific fractures we found an association with femur fractures both in females 4.06 [95% CI: 3.39 to 4.46] and in males 2.79 [95% CI: 1.45 to 2.37] and for fractures of the spine (females 2.38 [95% CI: 2.00 to 2.84], males 2.31 [95% CI: 1.20 to 4.42]). The aHR of any fracture decreased from 1.66 [95% CI: 1.52 to 1.81] in the period from 1977 to 1997 to 1.40 [95% CI: 1.33 to 1.40] from 1998 to 2018. In conclusion, we found that AN was associated with a 46% increased risk of any fracture up to 40 years after diagnosis. We found no overall increased risk in males, but in both sexes we found a particularly high site-specific fracture risk in the spine and femur. Fracture risk decreased in recent decades, indicating that more patients with AN have been diagnosed with presumably less severe disease and that the earlier detection and intervention of AN in recent years may translate into a lower facture risk. © 2023 The Authors.

Motor function in early onset schizophrenia-A 2-year follow-up study

AIM

Motor symptoms primarily assessed by clinical rating are documented across the schizophrenia spectrum, but no studies have examined the longitudinal course of these symptoms in adolescents using tests that control for the natural maturational process. The aim is therefore to compare fine and gross motor function using age-adjusted tests in adolescents with schizophrenia and controls across a 2-year period, and examine if clinical correlates contribute to changes in motor function in adolescents with schizophrenia.

METHOD

Motor function assessed by two age-adjusted tests was compared in 25 adolescents with schizophrenia and age- and sex-matched controls over a 2-year period using t-tests, Cohen's D and χ2 tests. Linear mixed models with a random intercept at patient level were used to assess changes between baseline and follow-up. The latter approach was adopted to assess the association between changes and potential predictors as age, sex, complications during labour/delivery, childhood motor function, symptoms severity, executive function and antipsychotics.

RESULT

All measures of motor function but one significantly differentiated adolescents with schizophrenia from controls with large effect sizes at 2-year follow-up. The overall scores did not change during follow-up, whereas two resembling motor areas of the tests significantly improved in adolescents with schizophrenia. The severity of schizophrenia, sex and IQ revealed association with the changes.

CONCLUSION

The finding of both stability and improvements from diagnosis to follow-up in adolescents with schizophrenia and the differences between adolescents with and without schizophrenia argue in favour of the neurodevelopment hypothesis and highlights the need for assessing motor function.

Eating disorder symptomatology among transgender individuals: a systematic review and meta-analysis

OBJECTIVE

The purpose of this systematic review and meta-analysis was to synthesize the literature on eating disorders and eating disorder symptomatology among transgender individuals and to summarize the existing literature on gender-affirming treatment and the prevalence of eating disorder symptomatology.

METHOD

The literature search for this systematic review and meta-analysis was performed in PubMed, Embase.com, and Ovid APA PsycInfo. We searched for "eating disorders" and "transgender" using both controlled vocabularies and natural language terms for their synonyms. The PRISMA statement guidelines were followed. Quantitative data from studies on transgender individuals and eating disorders assessed with relevant assessment tools was included.

RESULTS

Twenty-four studies were included for the qualitative synthesis, and 14 studies were included in the meta-analysis. The results revealed higher levels of eating disorder symptomatology among transgender individuals compared with cisgender individuals, especially cisgender men. Transgender men tend to display higher levels of eating disorder symptomatology than transgender women; however, transgender women seem to have higher levels of eating disorder symptomatology than cisgender men and, interestingly, this study also noted a trend toward transgender men having higher levels of eating disorders than cisgender women. Gender-affirming treatment seems to alleviate the presence of eating disorder symptomatology in transgender individuals.

DISCUSSION

The body of research on this subject is extremely limited, and transgender individuals are underrepresented in the eating disorder literature. More research investigating eating disorders and eating disorder symptomatology in transgender individuals and the relationship between gender-affirming treatment and eating disorder symptomatology is needed.

The gut microbiota contributes to the pathogenesis of anorexia nervosa in humans and mice

Anorexia nervosa (AN) is an eating disorder with a high mortality. About 95% of cases are women and it has a population prevalence of about 1%, but evidence-based treatment is lacking. The pathogenesis of AN probably involves genetics and various environmental factors, and an altered gut microbiota has been observed in individuals with AN using amplicon sequencing and relatively small cohorts. Here we investigated whether a disrupted gut microbiota contributes to AN pathogenesis. Shotgun metagenomics and metabolomics were performed on faecal and serum samples, respectively, from a cohort of 77 females with AN and 70 healthy females. Multiple bacterial taxa (for example, Clostridium species) were altered in AN and correlated with estimates of eating behaviour and mental health. The gut virome was also altered in AN including a reduction in viral-bacterial interactions. Bacterial functional modules associated with the degradation of neurotransmitters were enriched in AN and various structural variants in bacteria were linked to metabolic features of AN. Serum metabolomics revealed an increase in metabolites associated with reduced food intake (for example, indole-3-propionic acid). Causal inference analyses implied that serum bacterial metabolites are potentially mediating the impact of an altered gut microbiota on AN behaviour. Further, we performed faecal microbiota transplantation from AN cases to germ-free mice under energy-restricted feeding to mirror AN eating behaviour. We found that the reduced weight gain and induced hypothalamic and adipose tissue gene expression were related to aberrant energy metabolism and eating behaviour. Our 'omics' and mechanistic studies imply that a disruptive gut microbiome may contribute to AN pathogenesis.

Involuntary treatment in patients with anorexia nervosa: utilization patterns and associated factors

BACKGROUND

A subgroup of patients with anorexia nervosa (AN) undergoing involuntary treatment (IT) seems to account for most of the IT events. Little is known about these patients and their treatment including the temporal distribution of IT events and factors associated with subsequent utilization of IT. Hence, this study explores (1) utilization patterns of IT events, and (2) factors associated with subsequent utilization of IT in patients with AN.

METHODS

In this nationwide Danish register-based retrospective exploratory cohort study patients were identified from their first (index) hospital admission with an AN diagnosis and followed up for 5 years. We explored data on IT events including estimated yearly and total 5-year rates, and factors associated with subsequent increased IT rates and restraint, using regression analyses and descriptive statistics.

RESULTS

IT utilization peaked in the initial few years starting at or following the index admission. A small percentage (1.0%) of patients accounted for 67% of all IT events. The most frequent measures reported were mechanical and physical restraint. Factors associated with subsequent increased IT utilization were female sex, lower age, previous admissions with psychiatric disorders before index admission, and IT related to those admissions. Factors associated with subsequent restraint were lower age, previous admissions with psychiatric disorders, and IT related to these.

CONCLUSIONS

High IT utilization in a small percentage of individuals with AN is concerning and can lead to adverse treatment experiences. Exploring alternative approaches to treatment that reduce the need for IT is an important focus for future research.

Living and leaving a life of coercion: a qualitative interview study of patients with anorexia nervosa and multiple involuntary treatment events

BACKGROUND

A small but significant group of patients with anorexia nervosa (AN) undergo multiple involuntary treatment (IT) events. To enhance our understanding of IT and potentially inform treatment, we explored experiences and perspectives on IT of these patients.

METHODS

We designed a qualitative semi-structured interview study and used reflexive thematic analysis. Participants were at least 18 years of age, had multiple past IT events (≥ 5) related to AN over a period of at least one month of which the last IT event happened within the preceding five years. Participants had no current IT, intellectual disability, acute psychosis, or severe developmental disorder. We adopted an inductive approach and constructed meaning-based themes.

RESULTS

We interviewed seven participants. The data portrayed a process of living and leaving a life of coercion with a timeline covering three broad themes: living with internal coercion, coercive treatment, and leaving coercion; and five subthemes: helping an internal battle, augmenting suffering, feeling trapped, a lasting imprint, and changing perspectives. We highlighted that patients with AN and multiple IT events usually experienced internal coercion from the AN prior to external coercion from the health care system. IT evoked significant negative affect when experienced, and often left an adverse imprint. Moreover, IT could help an internal battle against AN and perspectives on IT could change over time.

CONCLUSIONS

Our study suggests that feeling internally coerced by AN itself sets the stage for IT. Clinicians should be conscious of the potential iatrogenic effects of IT, and reserve IT for potentially life-threatening situations.

Patients' perspectives on screening for disordered eating among adolescents with type 1 diabetes

PURPOSE

People with type 1 diabetes have an increased risk of disordered eating (DE) and eating disorders (ED). Screening is recommended however little is known about patients' perspectives on screening questionnaires. This paper reports qualitative analyses of patients' perspectives on the questionnaire Diabetes Eating Problem Survey Revised (DEPS-R), including acceptability, attitudes, and cognitive understanding.

RESEARCH DESIGN AND METHODS

15 adolescents with type 1 diabetes between 11 and 18 years, were interviewed. A semi-structured format and a qualitative Interpretive Descriptive (ID) methodology was chosen.

RESULTS

The analyses identified four themes: (1) The Questionnaire, (2) Reframing Diabetes Visits, (3) This is (not) for me, and (4) Out in the Open. The DEPS-R was completed with-in 5-10 min. with no technical difficulties. The questionnaire altered the diabetes visit for some, creating a new dialog, and time for self-reflection. Adolescents appreciated the direct approach in the questionnaire, and showed willingness to complete the questionnaire, when presented to them by a health care professional (HCP). One item in the DEPS-R proved difficult to understand for some participants.

CONCLUSION

The study highlights DEPS-R as a clinically relevant screening questionnaire. Completing DEPS-R prior to a consultation opens the door to a consultation that invites the adolescent to address matters of eating behavior. Our findings suggest that systematic screening of DE/ED using the DEPS-R is both accepted and welcomed by adolescents with type 1 diabetes. Future research should focus on a potential update of selected items in DEPS-R.

Pharmacotherapy in anorexia nervosa: A Danish nation-wide register-based study

OBJECTIVE

No medications have been indicated for the treatment of anorexia nervosa (AN). Nonetheless, individuals with AN are frequently treated pharmacologically. The present study maps nationwide pharmacotherapy two years before to five years after first AN diagnosis.

METHODS

We identified all medication prescriptions in a national register-based study of patients with a first diagnosis of AN between 1998 and 2011, and age and gender matched controls (1:10). Medication classes were compared using odds ratios (OR) between patients and controls; between patients below and above 15 years; between patients with and without comorbidity; and between those diagnosed before or after 2005.

RESULTS

The odds of pharmacotherapy were increased in patients for all classes of medication except a small residual class. Highest odds were found for alimentary (OR 2.8, p < 0.001) and psychopharmacological (OR 5.5, p < 0.001) medication. The former peaked one year prior to first diagnosis and the latter one year after. Older patients had increased risk of almost all medication classes with cardiovascular medication showing a fivefold OR (p < 0.001). Patients with psychiatric comorbidity had a threefold OR for psychopharmacological medication (p < 0.001) compared to patients without psychiatric comorbidity. Calendar year showed few and small differences.

CONCLUSION

The extended use of all medication classes both prior to and after first diagnosis of AN highlights the severe cause and complexity of AN. The results encourage clinical caution of pharmacotherapy, highlight the need for pharmacotherapy guidelines for AN, and emphasize the urgency of research in pharmacotherapy in AN.

Influence of eating disorder psychopathology and general psychopathology on the risk of involuntary treatment in anorexia nervosa

PURPOSE

We explored associations between clinical factors, including eating disorder psychopathology and more general psychopathology, and involuntary treatment in patients with anorexia nervosa. Our intention was to inform identification of patients at risk of involuntary treatment.

METHODS

This was a retrospective cohort study combining clinical data from a specialized eating disorder hospital unit in Denmark with nationwide Danish register-based data. A sequential methodology yielding two samples (212 and 278 patients, respectively) was adopted. Descriptive statistics and regression analyses were used to explore associations between involuntary treatment and clinical factors including previous involuntary treatment, patient cooperation, and symptom-level psychopathology (Eating Disorder Inventory-2 (EDI-2) and Symptom Checklist-90-Revised (SCL-90-R)).

RESULTS

Somatization (SCL-90-R) (OR = 2.60, 95% CI 1.16-5.81) and phobic anxiety (SCL-90-R) (OR = 0.43, 95% CI 0.19-0.97) were positively and negatively, respectively, associated with the likelihood of involuntary treatment. Furthermore, somatization (HR = 1.77, 95% CI 1.05-2.99), previous involuntary treatment (HR = 5.0, 95% CI 2.68-9.32), and neutral (HR = 2.92, 95% CI 1.20-7.13) or poor (HR = 3.97, 95% CI 1.49-10.59) patient cooperation were associated with decreased time to involuntary treatment. Eating disorder psychopathology measured by the EDI-2 was not significantly associated with involuntary treatment.

CONCLUSIONS

Clinical questionnaires of psychopathology appear to capture specific domains relevant to involuntary treatment. Poor patient cooperation and previous involuntary treatment being associated with shorter time to involuntary treatment raise important clinical issues requiring attention. Novel approaches to acute anorexia nervosa care along with unbiased evaluation upon readmission could mitigate the cycle of repeat admissions with involuntary treatment.

A benchmark study of a combined individual and group anorexia nervosa therapy program

OBJECTIVE

Anorexia nervosa (AN) is a treatment-resistant illness. Up to half of the patients show limited or no significant treatment response. First, we aimed to describe a new stepped-care outpatient treatment combining group and individual therapy (CIGAN) with a strong focus on normalizing eating and weight and in vivo meal support for adults with moderate to severe AN. Second, we aimed to compare CIGAN with specialized treatments of Specialized Supportive Clinical Management (SSCM) and the Maudsley model of AN (MANTRA).

METHOD

The study includes 137 adults with moderate to severe AN and the primary outcome (BMI) at six and twelve months was compared with the outcomes published for SSCM and MANTRA using the Chi-squared test and Student's t-test. The paired t-test and Cohen's d were used to compare the within-group follow-up data with the baseline data.

RESULTS

CIGAN patients changed significantly on all outcome measures at 6 and 12 months, with effect sizes on BMI of 1.37 and 1.51 and on the weight of 1.36 and 1.60, respectively. Except for the 12-month comparison with MANTRA, patients had a higher BMI and larger BMI increase at both 6 and 12 months than SSCM (BMI p = 0.002 and 0.023, BMI increase p < 0.001 and 0.003) and MANTRA (BMI p = 0.031 and 0.168, BMI increase p < 0.001 and 0.037).

DISCUSSION

CIGAN, including a stepped care approach, is a promising treatment, and further research on the effective elements is warranted.

Comparing the Movement Assessment Battery for Children with the Bruininks‐Oseretsky Test of Motor Proficiency in adolescents with and without schizophrenia

BACKGROUND

As motor impairments have implications for health and functioning, they need to be addressed early, not only in childhood but also in adolescence, the period in which mental disorders as schizophrenia, typically develops. Further, the possible prognostic value of motor impairments in schizophrenia highlights the importance. The Bruininks-Oseretsky Test of Motor Proficiency (BOT-2) and the Movement Assessment Battery for Children (MABC-2) assess adolescent motor performance. However, MABC-2 is not valid past age 16 and has no sex-norms. Further, while the concurrent validity between the tests and their ability to distinguish between clinical and non-clinical groups has been established in children, however they have not been established in adolescence.

PURPOSE

To compare the ability of MABC-2 and BOT-2 to distinguish between adolescents with and without schizophrenia, to examine the concurrent validity between tests, to examine the agreement between tests in classifying adolescents "at risk" or scoring "below average" and to examine the influence of age and sex on MABC-2.

METHOD

Motor performance assessed by BOT-2 and MABC-2 was compared in 25 adolescents with schizophrenia (14-18) and age- and sex-matched controls using t-test, Cohen's D and false discovery rate's q-value. The associations between tests were assessed using Pearson's correlation and Lin's concordance correlation coefficient. The Kappa coefficient was used to assess the agreement between tests in classifying "risk/below average" and linear regression was adopted to assess the influence of age/sex on MABC-2.

RESULTS

MABC-2 and BOT-2 significantly distinguished adolescents with schizophrenia from controls with large effect size. A strong association (p > 0.001) was found between the tests. The tests revealed moderate agreement in identifying "risk" or scoring "below average". Only sex influenced MABC-2 scores.

CONCLUSION

MABC-2 and BOT-2 are both useful for assessing motor performance and distinguishing between adolescents with and without schizophrenia, although BOT-2 provides a more detailed picture of the challenges in adolescent with schizophrenia.

Pharmacogenetic CYP2D6 variability, phenoconversion and treatment outcomes: A Danish population-based cohort study in 6,798 individuals initiating atomoxetine treatment

Introduction

Atomoxetine, a first-line treatment option for ADHD, is affected by pharmacogenetic (PGx) variation of the drug-metabolizing enzyme CYP2D6. Despite the recommendation of CYP2D6 testing, the use of PGx-guided dosing remains low in Denmark.

Objectives

We investigated wide-ranging clinical outcomes in atomoxetine users in association with PGx variability.

Methods

We analyzed 6,798 individuals (55% children) with a first prescription for atomoxetine identified from the Danish population-based iPSYCH case-cohort study linking biobank information with Danish registers. Individuals were categorized based on their single-nucleotide-polymorphism-based CYP2D6 genotype into normal (NM), intermediate (IM), and poor metabolizer (PM). Clinical outcomes included treatment switching, discontinuation, psychiatric inpatient-, outpatient-, and emergency contact, suicide attempt/self-harm, sleep problem, and depression. Individuals’ CYP2D6-status could change due to drug-drug-interactions of weak, intermediate, or strong-CYP2D6 inhibitors (phenoconversion), which we accounted for by time-varying phenotype assessment. Incidence rate ratios (IRR) were estimated using Poisson regression analyses and adjusted for a wide range of potential confounders and covariates.

Results

Over two-thirds of the individuals had a hospital diagnosis of ADHD at the first atomoxetine prescription. The distribution of CYP2D6 phenotypes was similar in children and adults. IM/PM children had a significantly higher risk of a sleeping problem compared with NM children (IRR 1.25, 95% CI 1.01-1.54). Compared with NM adults, those with IM/PM had a higher risk of switching (1.15, 95% CI 0.98-1.35).

Conclusions

This is the first study showing the potential impact of PGx variability on clinical outcomes of atomoxetine users in a population-based setting, highlighting the utility of PGx testing.

Motor impairments in early onset schizophrenia

AIM

Motor impairments are frequent both at and before diagnosis. In childhood, impairments in general fine and gross motor function are among others identified using test batteries, and while elements of coordination are assessed in onset schizophrenia, the assessment of general motor functions is absent. Thus, we aimed to assess general motor function including childhood motor function in adolescents with schizophrenia in comparison with healthy controls and examine clinical correlates to general motor function.

METHOD

General fine and gross motor function was assessed using two standardized age-normed test batteries and a questionnaire in 25 adolescents with schizophrenia compared with age and gender-matched controls using t-test and χ² -test. Stepwise linear regression assessed potential developmental predictors on motor function including complications during childbirth, reported childhood motor function, executive function including false discovery rate q-values. Associations with schizophrenia symptom severity, executive function, cognitive function were assessed using Pearson's correlation and the impact of antipsychotic medication using t-test.

RESULT

All measures of motor function but one significantly differentiated adolescents with schizophrenia from healthy controls. The presence of schizophrenia (β =4.41, β = 10.96), explained the main part of the variance however, childhood motor function (β = .08) also added significantly to motor function. Executive function (β = -.45) was important for childhood motor function. Severity of schizophrenia was associated with strength (p < .0011) and manual coordination (p = .0295), and receiving antipsychotics affected manual dexterity (p = .0378).

CONCLUSION

The documentation of significant differences in general motor function in early onset schizophrenia compared with healthy controls highlights the need for general motor assessments and potential interventions.

The first 20 weeks of pregnancy is a high-risk period for eating disorder relapse

OBJECTIVE

Eating disorders (ED) are associated with adverse pregnancy outcome and pregnancy is associated with both relapse and remission of ED. Knowledge is lacking on the risk of ED relapse during pregnancy and the postpartum period for women in stable remission. This study examined the occurrence of perinatal ED relapse as well as obstetric and postpartum outcome in women with at least a 6-month ED remission before pregnancy.

METHOD

A total of 122 women in stable remission before pregnancy were included in a prospective longitudinal study. Changes in ED symptoms based on the Eating Disorder Examination were systematically evaluated at each antenatal visit and in the postpartum period.

RESULTS

A total of 30 (25%) women relapsed. Twenty women relapsed within the first 20 weeks of pregnancy and eight in the early weeks postpartum. Severe postpartum depression symptoms (33%) were frequent in women with ED relapse; hyperemesis gravidarum (30%) was frequently present independent of the woman's relapse status.

DISCUSSION

To prevent relapse of ED and possible consequences, attention to relapse in women in stable remission is especially important in early pregnancy and in the postpartum period.

Early repolarization pattern in adult females with eating disorders

INTRODUCTION

The risk of cardiovascular death is increased in patients with eating disorders (ED), but the background for this is unknown. Early repolarization pattern (ERP) on the electrocardiogram (ECG) has been associated with increased risk of sudden cardiac death.

METHODS

We investigated the prevalence of ERP in 233 female patients with anorexia nervosa (AN) and bulimia nervosa (BN) (age 18-35 years) compared with 123 healthy female controls.

RESULTS

Early repolarization pattern was present in 52 (22%) of ED patients (16 (15%) AN patients and 36 (29%) BN patients) and 17 (14%) of healthy controls. When adjusting for age, BMI, heart rate, use of selective serotonin reuptake inhibitors (SSRI), and potassium level, the odds ratio (OR) for ERP was 2.1 (95% CI 1.1-4.2, p = .03). There was an increased prevalence of inferolateral ERP in patients with ED compared with healthy controls (OR = 4.3, 95% CI 1.7-11.3, p = .003) as well as ERP with a downward/horizontal sloping ST segment (OR = 3.1, 95% CI 1.3-7.6, p = .01). Additionally, J-point elevation >0.2 mV was more prevalent in patients with ED (OR = 3.3, 95% CI 1.1-9.7, p = .03).

CONCLUSION

The prevalence of ERP was increased in patients with ED compared with healthy controls. This finding may provide a possible explanation for the increased cardiovascular mortality in ED patients.

Factor analysis of the eating disorder examination in a sample of female adolescents and adults with eating disorders

OBJECTIVE

Studies of the construct validity of the Eating Disorder Examination (EDE) show mixed results and none have included samples of adults with a sole diagnosis of either anorexia nervosa or bulimia nervosa. Thus, we examine the EDE's construct validity in a Danish clinical sample of adolescents and adults with eating disorders.

METHOD

Confirmatory factor analyses of the four-factor model indicated by the original four subscales and subsequent ad hoc exploratory factor analyses were performed in a sample of patients with eating disorders (N = 1,586) divided into five subsamples based on age and diagnosis: (a) adolescents with anorexia nervosa, (b) women with anorexia nervosa, (c) women with bulimia nervosa, and women with atypical versions of (d) anorexia nervosa, and (e) bulimia nervosa.

RESULTS

The four-factor model was not confirmed in these five subsamples. Subsequent exploratory factor analyses did not reveal a single model fit for all five groups. Rather, eating-disorder symptoms can be understood through a one-, two-, or three-factor model depending on the subsample.

DISCUSSION

The four-factor model indicated by the original EDE subscales cannot be supported. The four subscales should be used with great care, if used at all, in trying to understand specific symptoms of eating disorders.

Patient use of a self-monitoring app during eating disorder treatment: Naturalistic longitudinal cohort study

OBJECTIVE

To explore patients' use of the self-monitoring app Recovery Record during 26 weeks of naturalistic eating disorder treatment.

METHODS

Selected patient characteristics at baseline were explored as predictors of app use using linear regression. Patients were grouped according to diagnosis (anorexia versus bulimia), and mixed-effects analyses were used to explore differences in app use between diagnoses across four time periods (weeks 1-4; weeks 5-8; weeks 9-12; weeks 13-26).

RESULTS

Eighty-four patients were included of which 41 had anorexia and 43 had bulimia. The total number of logs varied greatly (mean (SD): 592 (628.50)), and patient app activity almost ceased at week 13. Increasing age and no previous eating disorder treatment predicted increased app activity (p = .007; p = .039, respectively). Patients with anorexia logged over four times more often than patients with bulimia in the last time period (median (CI): 4.27 (1.28;14.31); p = .018). Time predicted declining app use (all p ≤ .007).

CONCLUSION

Future research on long-term app engagement should investigate associations between patients' app use and changes in their eating disorder symptom severity over time.

Factors Associated with a Delayed Autism Spectrum Disorder Diagnosis in Children Previously Assessed on Suspicion of Autism

This study aimed to investigate factors associated with a delayed autism spectrum (ASD) diagnosis when compared to children with either no or early ASD diagnosis. Among 893 children assessed for ASD before age 8, 39% had no ASD at baseline, of which 21% received a later ASD diagnosis. Autism symptoms, diagnostic history of other developmental disorders, cognitive ability, and socioeconomic factors were associated with delayed ASD. Autism Diagnostic Observation Schedule (ADOS) scores in delayed ASD fell between early and no ASD. Other developmental disorders, time and clinical trends like ADOS use and low parental education distinguished delayed and early ASD, whereas higher frequency of IQ < 70 at baseline and a diagnosis of emotional disorders during follow-up distinguished delayed and no ASD.

Integrating feral cat (Felis catus) control into landscape-scale introduced predator management to improve conservation prospects for threatened fauna: a case study from the south coast of Western Australia

Abstract ContextFeral cat predation has had a significant impact on native Australian fauna in the past 200 years. In the early 2000s, population monitoring of the western ground parrot showed a dramatic decline from the pre-2000 range, with one of three meta-populations declining to very low levels and a second becoming locally extinct. We review 8 years of integrated introduced predator control, which trialled the incorporation of the feral cat bait Eradicat® into existing fox baiting programs. AimsTo test the efficacy of integrating feral cat control into an existing introduced predator control program in an adaptive management framework conducted in response to the decline of native species. The objective was to protect the remaining western ground parrot populations and other threatened fauna on the south coast of Western Australia. MethodsA landscape-scale feral cat and fox baiting program was delivered across south coast reserves that were occupied by western ground parrots in the early 2000s. Up to 500000ha of national parks and natures reserves were baited per annum. Monitoring was established to evaluate both the efficacy of landscape-scale baiting in management of feral cat populations, and the response of several native fauna species, including the western ground parrot, to an integrated introduced predator control program. Key resultsOn average, 28% of radio-collared feral cats died from Eradicat® baiting each year, over a 5-year period. The results varied from 0% to 62% between years. Changes in site occupancy by feral cats, as measured by detection on camera traps, was also variable, with significant declines detected after baiting in some years and sites. Trends in populations of native fauna, including the western ground parrot and chuditch, showed positive responses to integrated control of foxes and cats. ImplicationsLandscape-scale baiting of feral cats in ecosystems on the south coast of Western Australia had varying success when measured by direct knockdown of cats and site occupancy as determined by camera trapping; however, native species appeared to respond favourably to integrated predator control. For the protection of native species, we recommend ongoing baiting for both foxes and feral cats, complemented by post-bait trapping of feral cats. We advocate monitoring baiting efficacy in a well designed adaptive management framework to deliver long-term recovery of threatened species that have been impacted by cats.

Perspectives on Involuntary Treatment of Anorexia Nervosa

Involuntary treatment of anorexia nervosa is an option in cases in which the patient's life or other people's lives are at risk or, in some countries, to prevent the deterioration of the illness. Involuntary treatment is often regarded as controversial and has been intensely debated, although typically with few references to documented knowledge. This paper provides a research perspective of the topic by examine data in the field of the involuntary treatment of anorexia nervosa to pinpoint present knowledge as well as areas demanding clinical action or research attention. The prevalence of involuntary treatment in general as well as specific measures is described and possible early markers of patients at risk of involuntary treatment are discussed. Studies including patients' perspectives of involuntary treatment show the complexity of this treatment, its initiation, and its consequences. To qualify future discussions, improve current practice, and minimize involuntary treatment in general as well as on an individual level, at least four areas need attention: (i) the present specific symptoms of anorexia nervosa and their imminent consequences, (ii) illness history, (iii) overall psychiatric symptoms and general functioning, and (iv) contextual sphere of the patient. In particular, the last two require attention from both clinicians and researchers. Furthermore, critical evaluation of the attitudes of both patients and health care professionals toward each other and the treatment is recommended.

QTc Interval and Risk of Cardiac Events in Adults With Anorexia Nervosa: A Long-Term Follow-Up Study

BACKGROUND

The literature contains several cases of anorexia nervosa (AN) patients with prolonged QTc interval. However, the risk of prolonged QTc interval is controversial and the risk of cardiac events in AN patients has yet to be investigated.

METHODS

We estimated the difference in mean QTc interval and relative risk of borderline prolonged QTc (>440 ms) and prolonged QTc (>460 ms) between 430 adult women AN patients and 123 healthy controls using 3 correction formulas. In a follow-up study, we estimated the risk of a primary end point (a composite of ventricular tachycardia, aborted cardiac arrest, and cardiac arrest) in AN patients compared with a population-based cohort derived from the Danish Civil Register.

RESULTS

Mean QTc for AN patients was 408 ms (Hodges), 402 ms (Fridericia), and 399 ms (Bazett). Hodges' found a slightly increased mean QTc (6.8 ms, 95% confidence interval, 1.6-12.0; P=0.01) and percentage with QTc >440 ms in AN patients (relative risk, 3.7, 95% confidence interval, 1.4-10.3; P=0.01), not observed with Fridericia's and Bazett's formulas. There was no difference in the risk of QTc >460 ms between AN patients and healthy controls. During a median follow-up of 10.1 years, AN patients had an increased risk of the primary end point compared with the population-based cohort (hazard ratio, 10.4, 95% confidence interval, 2.6-41.6; P=0.001). However, absolute numbers were small with cumulative incidences of 0.5% and 0.07%, respectively, after 10 years. No events occurred in any AN patient with QTc >440 ms. All-cause mortality was also significantly increased in AN patients compared with the population-based cohort (hazard ratio, 11.2, 95% confidence interval, 5.1-24.5; P<0.001).

CONCLUSIONS

Overall, there was no difference in mean QTc interval or risk of prolonged QTc between AN patients and healthy controls. However, AN patients had a notably increased all-cause mortality, as well as an increased risk of cardiac events, which was not related to the baseline QTc interval.

Randomized, controlled, superiority study of extended duration of therapy with an intramammary antibiotic for treatment of clinical mastitis

The objectives of this study were to evaluate the efficacy of therapy of clinical mastitis following intramammary infusion of 2 durations of intramammary antibiotic therapy and to analyze clinical and microbiology data at enrollment or within 4 d of commencement of treatment as potential predictors of subsequent clinical and bacteriological cure. A total of 304 glands were randomly assigned to intramammary treatment with a combination of amoxicillin, clavulanic acid, and prednisolone either 3 times at 12-h intervals (3×12, n = 156) or 5 times at 12-h intervals (5×12 hourly, n = 148). At enrollment (d 0), assessments were made of the cow's demeanor, rectal temperature, teat-end hyperkeratosis, presence of heat or swelling of the gland, presence of clots in the milk, and California Mastitis Test (CMT) score. Cows were revisited on d 4, 14, and 21 and assessed for rectal temperature, the presence of clots in milk, heat or swelling of the gland, and CMT score. Milk samples were collected from enrolled glands for bacteriology (d 0, 4, 14, and 21) and for somatic cell count (d 14 and 21). Data were analyzed using generalized linear models. Treatment group was the key independent variable, but herd was included in the models. Other potentially confounding variables were included where associated at the bivariate level. A second series of analyses were undertaken to predict likelihood of clinical and bacteriological cure using the clinical signs cow age and days in milk, as well as bacteriological results at d 0 and 4. Although we found a higher clinical failure rate in the 3×12 than 5×12 hourly treatment group (28.2 ± 5.0 vs. 13.4 ± 3.6%, respectively), we noted no difference in bacteriological cure percentage (73.3 ± 7.8 vs. 72.0 ± 7.4%, respectively). The presence of heat or swelling at d 4, days in milk at initiation of treatment, age of the cow, and change in CMT score between d 0 and 4 were predictive of clinical and bacteriological cure. We concluded that increasing the duration of treatment resulted in significantly fewer clinical failures, but had no effect on cure proportion, somatic cell count, or new infection rate. Knowledge of cow age and days in milk and clinical signs were predictive of clinical and bacteriological cure proportion and may provide guidance for producers, under veterinary direction, as to when to extend or recommence therapy.

The QTc interval and risk of cardiac events in bulimia nervosa: A long-term follow-up study

OBJECTIVE

An association between bulimia nervosa (BN) and prolonged corrected QT interval (QTc) in the electrocardiogram has been suggested, but results of previous studies are conflicting, and the risk of cardiac events in patients with BN has yet to be investigated.

METHOD

We estimated mean QTc interval and relative risk of borderline (QTc >440 ms) and prolonged QTc (QTc >460 ms) between adult women with BN (N = 531) and healthy controls (N = 123). In follow-up analyses, we investigated the risk of a primary endpoint (syncope, ventricular tachycardia, and cardiac arrest) and all-cause mortality in patients with BN (N = 702) compared with a population-based cohort derived from the Danish Civil Register (N = 7,020).

RESULTS

Mean QTc did not differ between patients with BN and controls. Relative risk of borderline prolonged QTc was 2.3 (p = 0.28). The number of patients and controls with prolonged QTc was small, and the risk did not differ between patients with BN and controls. Median follow-up was 10.6 years. Although there appeared to be increased risks after 5 years of follow-up, long-term risks of the primary endpoint (Hazard ratio [HR] = 1.4, p = 0.37) and all-cause mortality (HR = 1.7, p = .28), respectively, were not increased in patients with BN compared to a population-based cohort.

DISCUSSION

Mean QTc did not differ between patients with BN and healthy controls, and the risk of prolonged QTc was not increased in patients with BN. There was no difference in the long-term risk of cardiac events, and long-term all-cause mortality did not differ significantly between patients with BN and a population-based cohort.

Grasping the weight cut-off for anorexia nervosa in children and adolescents

OBJECTIVE

The Diagnostic and Statistical Manual of Mental Disorders 5 suggests the 5th age-adjusted body mass index (BMI) percentile as the numeric cut-off for anorexia nervosa (AN) in children and adolescents. We aimed to investigate the degree to which the 5th age-adjusted percentile as the numeric cut-off for AN in youths reflects the clinical population of patients accepted for treatment.

METHOD

From a specialized eating disorder clinic, 305 patients with AN below 18 years of age were grouped according to age-adjusted BMI percentiles [below the 5th (low), above the 10th (high), and between the 5th and the 10th (medium)]. The distribution of eating disorder diagnoses and severity measured by the Eating Disorder Examination was compared.

RESULTS

Full-syndrome anorexia nervosa (F.50.0) was found in 182 (59.5%) patients and atypical anorexia nervosa (F.50.1) in 123 patients (40.5%). The number of patients in the low, medium, and high BMI percentile groups was 189 (62.0%), 34 (11.1%), and 82 (26.9%), respectively. Patients in the low BMI group differed from patients in the medium BMI group by a lower frequency of vomiting. The high BMI group presented with more weight and shape concern than the lower BMI group. Age was not a confounder of these associations.

DISCUSSION

We question the applicability of the 5th BMI percentile as a substantiated cut-off for the weight criterion in anorexia nervosa in youths and argue that the cut-off should not be ascribed great clinical importance as this may hinder early detection of illness and initiation of treatment.

A Danish register-based study on involuntary treatment in anorexia nervosa

OBJECTIVE

Involuntary treatment is controversial and widely debated, but remains a significant component of treatment for severe anorexia nervosa. Given how little is known about this topic, we describe the frequency of various involuntary measures in a national cohort of all patients diagnosed with anorexia nervosa. In a subsample of patients, we explored predictors of the first involuntary measure recorded.

METHOD

Descriptive statistics and Cox proportional hazard analyses were conducted using the national registers of Denmark covering the total population. Data from the National Patient Register and the Psychiatric Central Research Register including all psychiatric visits from 1969 onwards were merged with data from the National Register on Coercion covering 1999 onward. Involuntary measures registered between 2000 and 2013 were analyzed.

RESULTS

A total of 4,727 patients with a diagnosis of anorexia nervosa representing 16,592 admissions were included. Eighteen percent experienced at least one involuntary measure. A variety of measures were used with tube feeding being the most frequent followed by mechanical restraint, involuntary medication, physical restraint, constant observation, and sedative medication. A subsample of 2% of AN patients had more than 100 involuntary measures recorded. The first recorded involuntary measure was predicted by most but not all psychiatric comorbidities, especially schizophrenia, autism spectrum, and personality disorders, older age at first diagnosis, and previous admissions.

DISCUSSION

It is important to develop a more granular understanding of patients at risk of requiring involuntary treatment and to determine how best to treat them effectively with minimal use of involuntary measures.

Patient Experiences Using a Self-Monitoring App in Eating Disorder Treatment: Qualitative Study

Background

The Recovery Record smartphone app is a self-monitoring tool for individuals recovering from an eating disorder. Unlike traditional pen-and-paper meal diaries, which are often used in eating disorder treatment, the app holds novel features, such as meal reminders, affirmations, and patient-clinician in-app linkage, the latter allowing for clinicians to continuously monitor patients' app data.

Objective

To explore patients' experiences with using Recovery Record as part of outpatient eating disorder treatment.

Methods

A total of 41 patients from a Danish eating disorder treatment facility were included in the study. All 41 patients participated in participant observations of individual or group treatment sessions, and 26 were interviewed about their experiences with using the app in treatment. The data material was generated and analyzed concurrently, applying the inductive methodology of Interpretive Description.

Results

The patients' experiences with Recovery Record depended on its app features, the impact of these features on patients, and their specific app usage. This patient-app interaction affected and was affected by changeable contexts making patients' experiences dynamic. The patient-app interaction affected patients' placement of specific Recovery Record app features along a continuum from supportive to obstructive of individual everyday life activities including the eating disorder treatment. As an example, some patients found it supportive being notified by their clinician when their logs had been monitored as it gave them a sense of relatedness. Contrarily, other patients felt under surveillance, which was obstructive, as it made them feel uneasy or even dismissing the app.

Conclusions

Some patients experienced the app and its features as mostly supportive of their everyday life and the eating disorder treatment, while others experienced it primarily as obstructive. When applying apps in eating disorder treatment, we therefore recommend that patients and clinicians collaborate to determine how the app in question best fits the capacities, preferences, and treatment needs of the individual patient. Thus, we encourage patients and clinicians to discuss how specific features of the applied app affect the individual patient to increase the use of supportive features, while limiting the use of obstructive ones.

Clinicians' perspective on an app for patient self-monitoring in eating disorder treatment

OBJECTIVE

The Recovery Record smartphone app is a self-monitoring tool for individuals recovering from eating disorders. Oppositely to traditional pen-and-paper meal diaries, the app allows for in-app patient-clinician linkage enabling clinicians to access patient app data anytime. The aim of our study was to explore the interdisciplinary clinical perspective on Recovery Record and its impact on treatment.

METHOD

Thirty-one clinicians from a Danish eating disorder treatment facility participated in field studies and 23 of these in interviews. Data were generated and analyzed concurrently applying the inductive methodology of Interpretive Description.

RESULTS

We found two overarching themes: "Access to app data between treatment sessions", and "The patient-clinician relationship". Sub-themes associated with the former were "Online obligations" in relation to the added workload of continuously monitoring patient app data, and "Prepared or prejudiced" relating to advantages and disadvantages of using patient app data as preparation for treatment sessions. Sub-themes pertaining to the latter were "Expectation discrepancy" in relation to patients' and clinicians' divergent expectations for app usage, and "Pacified patients" regarding the clinicians' experience that the app potentially compromised the patient initiative in treatment sessions.

DISCUSSION

Recovery Record induced new and affected pre-existing treatment and work conditions for clinicians. Clinicians were preoccupied with challenges associated with the app, for example, an added work load and potential harm to the patient-clinician collaboration. Thus, prior to adopting the app, we encourage clinicians and managements to discuss the objectives, advantages and disadvantages of adopting the app, and outline specific guidelines for patient and clinician app usage.

The impact of bariatric surgery on quality of life: a systematic review and meta-analysis

This study aims to review the obesity literature in order to assess the impact of bariatric surgery on quality of life and the between-study variation by examining the standardized mean magnitude of effect in change in the levels of quality of life. The following databases EMBASE, PubMed, PsycINFO, CINAHL, the Cochrane Library and Web of Science were systematically searched for studies examining change in quality of life in adults receiving bariatric surgery for obesity. Seventy-two studies were included with a total of 9,433 participants treated for obesity with bariatric surgery. The average impact of bariatric surgery on quality of life corresponded to an effect size of 0.88 (95% CI: 0.80-0.96), indicating that bariatric surgery has a significant positive influence on quality of life in general. The impact varied considerably across studies with bariatric surgery showing a significantly greater positive influence on physical quality of life compared to mental quality of life. Bariatric surgery is effective in improving quality of life, especially when looking at physical well-being. Greater focus on the psychological well-being of the person undergoing surgery for obesity may lead to a better post-surgery prognosis for more people.

The association between interpersonal problems and treatment outcome in the eating disorders: A systematic review

OBJECTIVE

To review systematically the eating disorder literature in order to examine the association between pre-treatment interpersonal problems and treatment outcome in people diagnosed with an eating disorder.

METHODS

Six relevant databases were searched for studies in which interpersonal problems prior to treatment were examined in relation to treatment outcome in patients diagnosed with anorexia nervosa (AN), bulimia nervosa (BN) or eating disorders not otherwise specified (EDNOS).

RESULTS

Thirteen studies were identified (containing 764 AN, 707 BN and 48 EDNOS). The majority of studies indicated that interpersonal problems at the start of therapy were associated with a detrimental treatment outcome.

CONCLUSIONS

Individuals with a binge/purge-type of eating disorder may be particularly vulnerable to interpersonal issues and these issues may lead to poorer treatment recovery by reducing the individual's ability to engage in the treatment process on a functional level. The clinical and research implications are discussed.

A systematic review of the frequency, duration, type and effect of involuntary treatment for people with anorexia nervosa, and an analysis of patient characteristics

OBJECTIVE

Involuntary treatment of anorexia nervosa is controversial and costly. A better understanding of the conditions that determine involuntary treatment, as well as the effect of such treatment is needed in order to adequately assess the legitimacy of this model of care. The aim of the present study was to investigate the frequency and duration of involuntary treatment, the characteristics of this group of patients, the kind of involuntary actions that are applied and the effect of such actions.

REVIEW

Relevant databases were systematically searched for studies investigating the involuntary treatment of individuals diagnosed with anorexia nervosa.

RESULTS

The studies included in the review contained people treated in an inpatient setting for severe or severe and enduring anorexia nervosa. People that were treated involuntarily were characterised by a more severe psychiatric load. The levels of eating disorder pathology between involuntary and voluntary groups were similar and the outcome of involuntary treatment was comparable in terms of symptom reduction to that of voluntary treatment.

CONCLUSION

Despite inconsistent findings, the comparable levels of eating disorder pathology observed between involuntary and voluntary patient-groups together with findings of higher co-morbidity, more preadmissions, longer duration of illness and more incidences of self-harm for involuntary patients suggest that involuntary treatment is not a reaction to the severity of eating disorder symptoms alone, but is most likely a response to the complexity of the patient's situation as a whole.

Change in cannabis use, clinical symptoms and social functioning among patients with first-episode psychosis: a 5-year follow-up study of patients in the OPUS trial

BACKGROUND

Several studies indicate that cannabis use among patients with psychotic disorders is associated with worse outcome, but only a few studies have controlled for baseline condition and medication.

METHOD

At 5-year follow-up, interviews were carried out with 314 first-episode psychosis patients included in the OPUS trial. The patients included were in the age range of 18 to 45 years old and 59% were male. Cannabis use was extracted from the Schedule for Clinical Assessment in Neuropsychiatry. At follow-up, the patients were divided into different groups according to the variable cannabis use: abstainers, stoppers, starters and continuers. Psychotic, negative and disorganized dimensions (ranging from zero to five) were calculated for each of the four groups based on the Schedule for the Assessment of Positive and Negative Symptoms in Schizophrenia.

RESULTS

Cannabis users were younger (24.6 years v. 27.4 years, p < 0.001) and had a lower level of education. At the 5-year follow-up, users of cannabis had higher scores on the psychotic dimension [difference 0.97, 95% confidence interval (CI) 0.41-1.53, p = 0.001] and lower levels of the Global Assessment of Functioning (difference 8.26, 95% CI 2.13-14.39, p = 0.01). Those who stopped using cannabis between entry and 5-year follow-up had a significantly lower level of psychotic symptoms at 5-year follow-up even after controlling for baseline level of psychotic symptoms and for insufficient antipsychotic medication (adjusted difference in psychotic dimension -1.04, 95% CI -1.77 to -0.31, p = 0.006).

CONCLUSIONS

Continuous cannabis use was associated with higher levels of psychotic symptoms after 5 years, and this association was only partly explained by insufficient antipsychotic medication.

97 IN VIVO AND IN VITRO EMBRYO PRODUCTION WITH Y-SEXED SORTED OR CONVENTIONAL SEMEN IN BEEF CATTLE

An experiment was designed to evaluate in vivo and in vitro embryo production following the use of frozen–thawed conventional or Y-sexed semen from a Brangus bull with known high fertility. For in vivo embryo production, Brangus heifers (n = 12) were superovulated twice in a crossover design and inseminated with sexed or conventional semen. On Day 0, all heifers received an intravaginal progesterone device (DIB 1 g, Syntex S.A., Buenos Aires, Argentina) and 2.5 mg oestradiol benzoate and 50 mg progesterone (Progestar, Syntex S.A.) by intramuscular injection (IM). On Day 4, heifers were superstimulated with 200 mg of NIH-FSH-P1 Folltropin-V (Bioniche Animal Health, Belleville, Ontario, Canada) in twice-daily decreasing doses over 4 days. In the a.m. and p.m. of Day 6, all heifers received PGF2a (Ciclase, Syntex) and DIBs were removed in the p.m.. In the a.m. of Day 8, heifers received 100 μg de Gonadolerin (Gonasyn, Syntex S.A.) and were randomly allocated to receive either one straw of conventional semen (24 × 106 sperm per dose) 12 and 24 h later or two straws of sexed semen (2.4 × 106 sperm per dose) 18 and 24 h after GnRH. Ova/embryos were collected nonsurgically on Day 15 and evaluated following IETS recommendations. Means were compared by t-test. Mean ( ± s.e.m.) number of ova/embryos, fertilized ova, and transferable embryos were 14.8 ± 2.7, 9.4 ± 1.8, and 7.1 ± 1.7 v. 16.8 ± 3.1, 9.9 ± 2.5, and 8.1 ± 2.0 for donors inseminated with conventional or sexed semen, respectively (P > 0.6). For in vitro production, oocytes were obtained from 50 ultrasound-guided follicle aspiration (OPU) sessions that was performed at random stages of the oestrous cycle and without superstimulation in 22 Brangus cows and heifers. Oocytes were classified and matured in TCM-199 medium with NaHCO3 and supplemented with 1% fetal bovine serum. Semen samples from the same bull used for in vivo embryo production were selected using Percoll and capacitated in Fert medium and used at a final concentration of sperm/mL for nonsexed semen and 2 × 106 sperm mL–1 for sexed semen. After 16 h (sexed) or 18 h (conventional) in Fert medium, zygotes were denuded and cultured in SOF supplemented with 0.4% BSA under oil at 37°C, 5% CO2 and saturated humidity for 7 days. The total number of oocytes matured and fertilized was 528 and 318 for conventional and sexed semen, respectively. Means were compared by t-test and proportions by chi-squared test. Mean (± s.e.m.) number of cleaved zygotes and blastocysts produced per OPU session did not differ between conventional (11.0 ± 1.4 and 7.1 ± 1.0) and sexed (8.7 ± 0.8 and 4.9 ± 0.7; P > 0.2) semen. However, the proportion of cleaved zygotes and blastocysts produced were significantly higher (P < 0.05) with conventional semen (61.2%; 329/538 and 39.4%; 212/538) than with sexed semen (54.4%; 173/318 and 30.8%; 98/318), respectively. In conclusion, comparable number of embryos can be obtained in vivo with sexed or conventional semen from a bull with proven high fertility. However, the proportion of blastocysts produced in vitro is likely to be reduced following the use of sexed as compared with conventional semen from the same bull.

Motivation to change in the eating disorders: a systematic review

OBJECTIVE

The aim of the study was to review the eating disorder literature in order to examine the effect of pretreatment autonomous/level of motivation to change on treatment outcome as measured by change in eating disorder pathology.

METHOD

Relevant databases were systematically searched for studies in which motivation to change prior to treatment was examined in relation to treatment outcome.

RESULTS

Pretreatment autonomous/level of motivation were associated with change in restrictive eating behaviors, bingeing behaviors, and cognitive/affective measures of eating disorder pathology. There was mixed support for the effect of motivation to change on global measures of eating disorder symptoms and virtually no support for the effect of motivation to change on purging behavior.

DISCUSSION

The level of pretreatment motivation the person exhibits prior to commencement of treatment appears to be helpful in predicting treatment outcome.

A five-item screening version of the Eating Disorder Inventory (EDI-3)

OBJECTIVE

The Eating Disorder Inventory (EDI) is used worldwide in research and treatment of eating disorders (EDs). Using the latest version (EDI-3: 91 items), we extracted the best screening items for a diagnosis of anorexia (AN) and bulimia (BN) nervosa.

METHOD

A patient sample of 561 women was recruited from an ED treatment centre in Denmark, and a comparison group of 878 women was randomly selected from the general population. An ED diagnosis was determined according to the Eating Disorder Examination Interview, yielding 84 AN and 202 BN patients.

RESULTS

Only two EDI items (Cronbach's α = .79) were needed to achieve a superior screening capability of BN (sensitivity = .94, specificity = .94). An adequate screening of AN was possible by using three items (α = .71; sensitivity = .91, specificity = .86).

DISCUSSION

The present study provides an even more economical and reliable screening of AN and BN compared with existing screening instruments. Implications for DSM-5 are also discussed.

The efficacy of a brief group CBT program in treating patients diagnosed with bulimia nervosa: a brief report

OBJECTIVE

The aim of the study was to evaluate the efficacy of a brief group cognitive behavior therapy (CBT) program in treating a large cohort of patients diagnosed with bulimia nervosa.

METHOD

Treatment outcome defined as reductions in bulimia related behavioral symptoms and bulimia related distress was examined in 205 consecutive new patients enrolled in an eight-session group CBT program.

RESULTS

Significant reductions in eating disorder pathology were found on all measures of bulimia related behavioral symptoms, as well as on all measures of bulimia related distress.

DISCUSSION

There is strong evidence for the efficacy of brief group CBT in treating patients with bulimia nervosa.

Diagnosis and treatment of subclinical mastitis in early lactation in dairy goats

The objectives of the study were to define the sensitivity and specificity of the California Mastitis Test (CMT) in determining the presence of intramammary infection in postpartum dairy goats and to determine whether antibiotic therapy increased bacteriological cure rate and lowered somatic cell count (SCC) compared with untreated controls. A CMT was performed and milk samples were collected for bacteriology from 211 glands of 106 does between 0 and 10 d after kidding. From a population of 3,239 glands from goats in 4 commercial herds, goats with one or both glands with a CMT score of >1 and from which bacteria were isolated were either assigned to be treated with 3 intramammary infusions at 12-h intervals of 75 mg of sodium ampicillin and 250 mg of sodium cloxacillin (n=57 glands) or left as untreated controls (n=49 glands). Milk samples were collected again 14 ± 3 and 21 ± 3 d later for bacteriology and SCC determination. Composite milk yield, goat SCC, length of lactation, and survival data were collected. A partial budget was constructed to assess the cost effectiveness of treatment. At a cut point of greater than trace, the sensitivity, specificity, and positive and negative predictive values of the CMT were 0.74, 0.74, 0.42, and 0.92, respectively. Treatment increased the bacteriological cure rate compared with no treatment [30/57 (53%) vs. 6/49 (12%)], but there was a pathogen by treatment interaction whereby treatment increased cure proportion in glands infected with minor, but not major, pathogens. Treatment reduced the foremilk gland-level SCC [1,595 (95% CI=1,106-2,300) vs. 3,028 (95% CI=2,091-4,385) geometric mean (× 1,000) cells/mL] but not the SCC at goat level [1,596 (95% CI=1,219-2,090) vs. 1,488 (95% CI=1,132-1,955) geometric mean (× 1,000) cells/mL] compared with no treatment. Milk yield, risk of removal from the herd, and length of lactation were not altered by treatment. Treatment resulted in a loss of NZ$20.39/doe. It was concluded that use of the CMT as a screening test resulted in a higher likelihood of finding a gland that would be infected than selecting a gland at random. Treatment increased bacteriological cure rate and reduced SCC at gland level compared with no treatment. However, at goat level, milk yield, SCC, and survival were not altered, resulting in no economic benefit of treatment.

Time to remission for eating disorder patients: a 2(1/2)-year follow-up study of outcome and predictors

The aim of the present study was to analyse outcome, time to remission, and predictors of time to remission in a cohort of Danish eating disorder patients. Seventy-eight patients (35 anorexic, 30 bulimic and 13 unspecified eating disorder patients) were interviewed 2(1/2) years after initial assessment. Method of assessment was Eating Disorder Examination (EDE), Longitudinal Interval Follow-up Evaluation of Eating Disorders (LIFE-EAT-II), Eating Disorder Inventory (EDI), Symptom Check List (SCL-90R), Present State Examination (PSE) and the Structured Clinical Interview for DSM-III-R Axis-II (SCID-II). Method of analysis was Kaplan-Meier estimate of survival, Log Rank test and Cox regression analysis. In total 48.7% reached remission with mean time to remission at 27 months. A trend difference between the diagnostic groups when measuring time to remission was found, i.e. patients with unspecified eating disorders remitted faster than bulimic (BN) patients who in turn remitted faster than anorexic (AN) patients. Body mass index (BMI) at baseline was the best predictor of time to remission for the total sample. Predictors differed when looking at diagnostic groups separately. Final outcome was comparable with earlier studies while relapse frequency was low. Patients with AN remitted faster than found in earlier survival analysis studies, while the remission rate for BN patients was comparable with earlier studies. Despite the prognostic value of BMI for the total sample, predictor analysis implied more disorder diversity than homogeneity.

Time course of symptom remission in eating disorders

OBJECTIVE

The study was carried out to test whether time to remission varies for different eating disorder symptoms.

METHOD

Sixty-five patients (35 anorexic patients and 30 bulimic patients) treated with psychotherapy were interviewed 2 1/2 years after initial assessment.

RESULTS

The anorexic physical symptoms remitted before the psychological symptoms of anorexia and bulimia nervosa, as did the bulimic behaviors: binging and purging. Nonpurging compensatory behavior and obsession with weight and shape were the last symptoms to remit. Differences between the anorexic and bulimic groups were found between the remission order of psychological symptoms.

DISCUSSION

In spite of different treatments and symptoms between patients, the results support the notion of a common pattern in the process of change including a long and stepwise course. The results detail a template of the course to recovery for eating disorders.
