Is Serum BDNF Altered in Acute,Short- and Long-Term Recovered Restrictive Type Anorexia Nervosa?

Brain-derived neurotrophic factor (BDNF), a neurotrophin involved in the regulation of food intake and body weight, has been implicated in the development and maintenance of Anorexia nervosa (AN). The majority of previous studies reported lower BDNF levels in acutely underweight AN patients (acAN) and increasing levels after weight rehabilitation. Here, we investigated serum BDNF concentrations in the largest known AN sample to date, both before and after weight restoration therapy. Serum BDNF was measured in 259 female volunteers: 77 in-patient acAN participants of the restrictive type (47 reassessed after short-term weight rehabilitation), 62 individuals long-term recovered from AN, and 120 healthy controls. We validated our findings in a post-hoc mega-analysis in which we reanalyzed combined data from the current sample and those from our previous study on BDNF in AN (combined sample: 389 participants). All analyses carefully accounted for known determinants of BDNF (age, sex, storage time of blood samples). We further assessed relationships with relevant clinical variables (body-mass-index, physical activity, symptoms). Contrary to our hypotheses, we found zero significant differences in either cross-sectional or longitudinal comparisons and no significant relationships with clinical variables. Together, our study suggests that BDNF may not be a reliable state- or trait-marker in AN after all.     

Racial Socialization in Transracial Adoptive Families: Does It Help Adolescents Deal With Discrimination Stress?

Racial socialization protects minority adolescents from stress associated with racial discrimination. The process of racial socialization, however, may be challenging in transracial adoptive families. White parents may struggle with preparing their children for discrimination and fostering the development of racial pride. Thus, transracially adopted youth may be particularly vulnerable to stress resulting from discrimination. This study examines the extent to which racial socialization by White adoptive parents moderates the link between discrimination and stress for their minority adolescents. A study of 59 parent‐child dyads indicated that while not having an independent effect, racial socialization did moderate the link between experiences of discrimination and perceived stressfulness. For those adolescents experiencing high levels of discrimination, racial socialization did serve a protective function.     

Does Short-term Diet Restriction in Mice Precipitate the Development of Anorexia?

Abstract

Anorexia nervosa (AN) inevitably begins with dieting. Yet, it is unknown whether anyone who will ultimately suffer from anorexia is already ill upon "going on a diet", or whether disease begins during, and is perhaps triggered by, dieting. The objective of the following study was to precipitate anorexia by imposing diet restriction on animals, as a model for generating AN in humans.

Three hundred young female Sabra mice were diet restricted to 40% of daily nutrient requirements for 12 days, lost 17% of body weight and were then re-fed ad-lib. All mice regained appetite and weight. Our conclusions are that diet restriction does not precipitate anorexia in mice. Our findings do not support a role for diet restriction per se in triggering AN.     

Addressing Reproductive Health in Hospitalized Adolescents—A Missed Opportunity

PurposeAdolescents are at high risk for sexually transmitted infections (STIs) and pregnancy. Since many adolescents have poor access to preventive care, hospitalizations present a critical opportunity to address adolescents' reproductive health. The purpose of this study was to assess provision of reproductive health services within a hospital setting.MethodsRetrospective study of a consecutive sample of adolescent patients aged 13 years and older hospitalized on the hospitalist service at a large academic pediatric tertiary care center. Measures included sexual history documentation, pregnancy and STI testing, Human papillomavirus immunization status and administration, and provision of contraception.ResultsOnly 55% of 150 patients had sexual history documentation, and of those, 47% endorsed sexual activity. Associations with increased likelihood of sexual history documentation included female patients (67% vs. 36%, p < .01), hospitalizations for ingestion (71% vs. 48%, p < .01), hospitalizations to hospital medicine compared with critical care (59% vs. 14%, p < .01), and admission note written by an intern compared with a senior resident, advanced practice provider, or fellow (67% vs. 44%, 29%, 13%, p < .01). Eighteen patients (12%) were tested for STIs. Only 19% of patients due for human papillomavirus immunization received it. Sixty percent of females received a pregnancy test. Contraception was provided in two encounters (2% of females).ConclusionsResults demonstrate a substantial missed opportunity to provide reproductive health services to hospitalized adolescents. Providers in hospital settings should optimize the opportunity to screen for sexual activity and reproductive health needs, provide indicated services, and offer education regarding reproductive health to hospitalized adolescents.     

Confidentiality With Adolescents in the Medical Setting: What Do Parents Think?

Purpose

When confidential health care is provided to adolescents they are more likely to seek care, disclose sensitive information, and return for future visits. Guidelines for health professionals recommend seeing young people alone to facilitate confidential care. We sought to document parental views regarding confidentiality with adolescents, aiming to identify topics that parents believe they should be informed about despite an assurance of confidentiality between their child and the doctor. We also aimed to document harms and benefits that parents associate with adolescents seeing doctors alone.

Methods

A sample of 86 parents attending an adolescent medicine clinic with their son/daughter was surveyed using a brief, anonymous questionnaire.

Results

Parents identified several benefits associated with confidential care, yet also believed they should be informed about a wide range of topics, even if their children did not want them to know. Parents' primary concern about confidentiality was a fear of not being informed about important information.

Conclusions

Parental views concerning confidentiality are complex and conflicting and differ from current guidance provided to health professionals. Ensuring that parents accurately understand the limits to confidentiality and support the notion of confidential care for their children is a challenging yet vital task for health professionals.     

Stability and Change of Adolescents’ Aggressive Behavior in Residential Youth Care

Background

Aggression in residential youth care institutions is a frequent problem.

Objective

The present short-term longitudinal study examined individual and institutional predictors of aggression in a group of 198 adolescents placed in open, semi-secure and secure residential institutions from the perspective of the importation and deprivation model.

Methods

A total of 198 adolescents in residential youth care filled in questionnaires regarding group climate and aggression with a 3 month interval. Hierarchical multiple regression analyses were performed to test the degree to which individual and contextual factors predict aggression.

Results

Very limited support was found for the effect of contextual factors; only repression showed a trend, predicting direct aggression, while gender composition of the living groups yielded a small effect. Girls placed in same-gender groups showed lower levels of indirect (relational) aggression compared to adolescents placed in mixed-gender or boys-only groups, even when controlled for gender and initial levels of aggression. Type of institution (i.e., level of security) did not predict differences in aggression. In particular individual characteristics of the adolescents were associated with later aggression, including initial levels of aggression, showing substantial 3 months stability, age and gender of the adolescents.

Conclusions

These findings are in line with research showing that aggression is relatively stable. Very limited support for environmental effects was found.

     

Does Inclusion of Interactions Result in Higher Precision of Estimated Health State Values?

Background

Most preference-based instruments producing overall values for health states are devised on the simplifying assumption that the overall effect of distinct health-related quality of life domains (attributes) of the instrument equals the sum of the attributes. Nevertheless, health attributes are often inter-related and depend on each other.

Chronically Connected? Internet Use Among Adolescents With Chronic Conditions

Little is known about Internet use among adolescents with chronic conditions (CCs). Our results indicate that CC females, but not males, are more likely to be heavy Internet users than their peers. CC youths are also more likely to visit health-related web sites, but less frequently than other sites.     

Does Media Use Result in More Active Communicators? Differences Between Native Dutch and Turkish-Dutch Patients in Information-Seeking Behavior and Participation During Consultations With General Practitioners

This study investigates differences between native Dutch and Turkish-Dutch patients with respect to media usage before and patient participation during medical consultations with general practitioners. In addition, the authors assessed the relation between patient participation and communication outcomes. The patients were recruited in the waiting rooms of general practitioners, and 191 patients (117 native Dutch, 74 Turkish-Dutch) completed pre- and postconsultation questionnaires. Of this sample, 120 patients (62.8%; 82 native Dutch, 38 Turkish-Dutch) agreed to have their consultations recorded to measure patient participation. Compared with Turkish-Dutch patients of similar educational levels, results showed that native Dutch patients used different media to search for information, participated to a greater extent during their consultations and were more responsive to their general practitioner. With respect to the Turkish-Dutch patients, media usage was related to increased patient participation, which was correlated with having fewer unfulfilled information needs; however, these relations were not found in the native Dutch patient sample. In conclusion, interventions that enhance participation among ethnic minority patients will better fulfill informational needs when such interventions stimulate information-seeking behavior in that group before a medical consultation.     

Emerging Technologies in the Treatment of Anorexia Nervosa and Ethics: Sufferers’ Accounts of Treatment Strategies and Authenticity

New neural models for anorexia nervosa (AN) are emerging as a result of increased research on the neurobiology of AN, and these offer a rationale for the development of new treatment technologies such as neuromodulation. The emergence of such treatment technologies raises new ethical questions; however these have been little discussed for AN. In this article, I take an empirical approach and explore how young women who suffer from AN perceive treatment technologies in light of the concept of authenticity. Interview data showed that participants in this study did not seem to unconditionally adhere to treatment modalities that only imply laborious self-work, such as therapy. The data also showed that they were willing to accept new treatment possibilities such as pharmacological or brain-directed treatment strategies, which they view as having potential instrumental value in coping with certain symptoms of the illness. However, such modalities can pose threats to patients’ authenticity, especially with regard to self-discovery. I argue that, in a context where there is an increased interest in brain-directed treatment strategies for AN, studies should continue to explore the ethical and psychological impact of such treatment technologies on individuals.
