Health related quality of life and psychopathological distress in risk taking and self-harming adolescents with full-syndrome, subthreshold and without borderline personality disorder: rethinking the clinical cut-off?

Background: Diagnostic standards do not acknowledge developmental specifics and differences in the clinical presentation of adolescents with borderline personality disorder (BPD). BPD is associated with severe impairments in health related quality of life (HRQoL) and increased psychopathological distress. Previously no study addressed differences in HRQoL and psychopathology in adolescents with subthreshold and full-syndrome BPD as well as adolescents at-risk for the development but no current BPD. Methods: Drawing on data from a consecutive sample of N = 264 adolescents (12–17 years) presenting with risk-taking and self-harming behavior at a specialized outpatient clinic, we investigated differences in HRQoL (KIDSCREEN-52) and psychopathological distress (SCL-90-R) comparing adolescents with no BPD (less than 3 criteria fulfilled), to those with subthreshold (3–4 BPD criteria) and full-syndrome BPD (5 or more BPD criteria). Group differences were analyzed using one-way analysis of variance with Sidak corrected contrasts or Chi-Square test for categorical variables. Results: Adolescents with subthreshold and full-syndrome BPD presented one year later at our clinic and were more likely female. Adolescents with subthreshold and full-syndrome BPD showed greater Axis-I and Axis-II comorbidity compared to adolescents with no BPD, and reported greater risk-taking behaviour, self-injury and suicidality. Compared to those without BPD, adolescents with subthreshold and full-syndrome BPD reported significantly reduced HRQoL. Adolescents with sub-threshold BPD and those with full-syndrome BPD did not differ on any HRQoL dimension, with the exception of Self-Perception. Similar, groups with sub-threshold and full-syndrome BPD showed no significant differences on any dimension of self-reported psychopathological distress, with the exception of Hostility. Conclusions: Findings highlight that subthreshold BPD in adolescents is associated with impairments in HRQoL and psychopathological distress comparable to full-syndrome BPD. Findings raise awareness on the importance of early detection and question the diagnostic validity and clinical utility of existing cut-offs. Findings support a lower diagnostic cut-off for adolescent BPD, to identify those at-risk at an early stage

Frequency and predictors of individual treatment outcomes (response, remission, exacerbation, and relapse) in clinical adolescents with nonsuicidal self-injury.

BACKGROUND Nonsuicidal self-injury (NSSI) is prevalent in adolescent clinical samples. There is evidence that NSSI can be treated effectively but data on individual treatment outcomes is limited. The goal of this study was to examine response, remission, exacerbation, and relapse rates over one and two years, respectively, among a clinical sample of adolescents with NSSI. Furthermore, we aimed to identify clinically relevant predictors of NSSI trajectories. METHODS The sample consists of n = 203 adolescents (12-17 y., 94% female) from a specialized outpatient clinic for risk-taking and self-harming behavior with NSSI on at least five days in the six months before first assessment. Assessments were completed at baseline and one (FU1) and two (FU2) years later using structured clinical interviews and self-report questionnaires. RESULTS At FU1, 75% reported a reduction in NSSI frequency by at least 50% (treatment response); among those, one third (25% of the entire sample) achieved a remission (0 NSSI); an exacerbation (⩾50% more NSSI) was observed in 11% of patients. Of those in remission, 41% relapsed one year later. Predictors of non-response or non-remission were inpatient treatment and depressive symptoms. Adolescents with lower NSSI frequency at baseline had a higher risk of exacerbation. Due to limited sample size at FU2 no prediction model for relapse was established. CONCLUSIONS While most adolescents presenting with NSSI achieved significant improvement, more attention should be paid to the rather low rates of full remission. Prediction and early detection of individuals who deteriorate during or relapse after treatment is critical

Self-rated risk as a predictor of suicide attempts among high-risk adolescents

Background: Predicting suicide attempts is a challenging task for clinicians and researchers, particularly among high-risk individuals (i.e. adolescents with lifetime suicide attempts). In this study, we examined whether adolescents were able to predict their own risk of attempting suicide in the future and whether borderline personality disorder (BPD) or depressive symptoms impacted the predictive value of self-ratings. Methods: Structured clinical assessments were conducted at baseline and after 12 months in a high-risk sample of treatment-seeking adolescents (n = 134; 12-17y.; 90% female) with at least one lifetime suicide attempt. Results: During the follow-up period, n = 51 participants (38%) attempted suicide at least once. Self-rated risk was a significant predictor for the recurrence of a suicide attempt, whereas BPD and depression were not. While there was no significant interaction between self-rated risk and BPD, a negative interaction emerged between self-rated risk and depression in the prediction of a suicide attempt. Greater depression severity diminished the predictive value of self-ratings. Limitations: Depression severity was measured using a questionnaire, not a clinical interview. The findings may not be applicable to less burdened samples. Conclusions: Asking high-risk adolescents to rate their own risk of attempting suicide appears to be an easy to apply method in improving the prediction of future suicide attempts in the clinical context

Tai Chi for Osteopenic Women: Design and Rationale of a Pragmatic Randomized Controlled Trial

Background: Post-menopausal osteopenic women are at increased risk for skeletal fractures. Current osteopenia treatment guidelines include exercise, however, optimal exercise regimens for attenuating bone mineral density (BMD) loss, or for addressing other fracture-related risk factors (e.g. poor balance, decreased muscle strength) are not well-defined. Tai Chi is an increasingly popular weight bearing mind-body exercise that has been reported to positively impact BMD dynamics and improve postural control, however, current evidence is inconclusive. This study will determine the effectiveness of Tai Chi in reducing rates of bone turnover in post-menopausal osteopenic women, compared with standard care, and will preliminarily explore biomechanical processes that might inform how Tai Chi impacts BMD and associated fracture risks. Methods/Design: A total of 86 post-menopausal women, aged 45-70y, T-score of the hip and/or spine -1.0 and -2.5, have been recruited from primary care clinics of a large healthcare system based in Boston. They have been randomized to a group-based 9-month Tai Chi program plus standard care or to standard care only. A unique aspect of this trial is its pragmatic design, which allows participants randomized to Tai Chi to choose from a pre-screened list of community-based Tai Chi programs. Interviewers masked to participants' treatment group assess outcomes at baseline and 3 and 9 months after randomization. Primary outcomes are serum markers of bone resorption (C-terminal cross linking telopeptide of type I collagen), bone formation (osteocalcin), and BMD of the lumbar spine and proximal femur (dual-energy X-ray absorptiometry). Secondary outcomes include health-related quality-of-life, exercise behavior, and psychological well-being. In addition, kinetic and kinematic characterization of gait, standing, and rising from a chair are assessed in subset of participants (n = 16) to explore the feasibility of modeling skeletal mechanical loads and postural control as mediators of fracture risk. Discussion: Results of this study will provide preliminary evidence regarding the value of Tai Chi as an intervention for decreasing fracture risk in osteopenic women. They will also inform the feasibility, value and potential limitations related to the use of pragmatic designs for the study of Tai Chi and related mind-body exercise. If the results are positive, this will help focus future, more in-depth, research on the most promising potential mechanisms of action identified by this study. Trial registration: This trial is registered in Clinical Trials.gov, with the ID number of NCT01039012

Global diabetes burden: analysis of regional differences to improve diabetes care.

peer reviewed[en] INTRODUCTION: The current evaluation processes of the burden of diabetes are incomplete and subject to bias. This study aimed to identify regional differences in the diabetes burden on a universal level from the perspective of people with diabetes. RESEARCH DESIGN AND METHODS: We developed a worldwide online diabetes observatory based on 34 million diabetes-related tweets from 172 countries covering 41 languages, spanning from 2017 to 2021. After translating all tweets to English, we used machine learning algorithms to remove institutional tweets and jokes, geolocate users, identify topics of interest and quantify associated sentiments and emotions across the seven World Bank regions. RESULTS: We identified four topics of interest for people with diabetes (PWD) in the Middle East and North Africa and another 18 topics in North America. Topics related to glycemic control and food are shared among six regions of the world. These topics were mainly associated with sadness (35% and 39% on average compared with levels of sadness in other topics). We also revealed several region-specific concerns (eg, insulin pricing in North America or the burden of daily diabetes management in Europe and Central Asia). CONCLUSIONS: The needs and concerns of PWD vary significantly worldwide, and the burden of diabetes is perceived differently. Our results will support better integration of these regional differences into diabetes programs to improve patient-centric diabetes research and care, focused on the most relevant concerns to enhance personalized medicine and self-management of PWD

CAST constraints on the axion-electron coupling

In non-hadronic axion models, which have a tree-level axion-electron interaction, the Sun produces a strong axion flux by bremsstrahlung, Compton scattering, and axiorecombination, the "BCA processes." Based on a new calculation of this flux, including for the first time axio-recombination, we derive limits on the axion-electron Yukawa coupling gae and axion-photon interaction strength ga using the CAST phase-I data (vacuum phase). For ma <~ 10 meV/c2 we find ga gae < 8.1 × 10−23 GeV−1 at 95% CL. We stress that a next-generation axion helioscope such as the proposed IAXO could push this sensitivity into a range beyond stellar energy-loss limits and test the hypothesis that white-dwarf cooling is dominated by axion emission

De vínculos, subjetividades y malestares contemporáneos

Este libro es una obra colectiva conformada por psicoanalistas argentinos que provienen de diversos campos del psicoanálisis que se dispusieron a poner en diálogo esa diversidad para establecer cruces, confrontaciones y enriquecimientos respecto de los tintes de época que caracterizan los modos de producción de las subjetividades y los malestares y sufrimientos que se ponen de manifiesto. Las y los autores establecen consideraciones respecto del entramado complejo entre lo intrasubjetivo, intersubjetivo y transubjetivo considerando que somos sujetos del vínculo y que el vínculo nos precede. Cada capítulo es recorrido por interrogantes y es posible establecer lecturas cruzadas entre ellos generando chispazos que despiertan al lector. Gran parte de esta obra fue escrita en el tiempo de inicio de la pandemia en 2020 de modo tal que cada capítulo revisiona la teoría a la luz de la actualidad de los hechos transitando un tiempo de incertidumbre y elaboración. Algunos interrogantes que plantea el libro son: ¿Es posible pensar un malestar estructural en la cultura? ¿De qué modo incide el desamparo social en la constitución subjetiva? ¿Cuánta diferencia puede tolerar un vínculo de pareja? ¿Por qué las parentalidades disidentes son exigidas a dar pruebas de su legitimidad? ¿Cuáles son las variaciones en las relaciones de poder entre varones y mujeres? ¿Qué ha sucedido con la autoridad parental en estos tiempos contemporáneos y cuál es el efecto de los cambios en los modos de ejercicio de la autoridad parental? ¿De qué manera la hipermodernidad y sus mandatos de época se ponen de manifiesto en nuevas configuraciones psicopatológicas? ¿La virtualidad y los soportes tecnológicos qué clase de temporalidad proponen y cómo ello impacta en la constitución psíquica? Cada uno de estos interrogantes pone en tensión la trama tejida entre los vínculos, las subjetividades y el malestardesde puntos de vista heterogéneos. Cada artículo explora postulados del psicoanálisis clásico en alternancia con producciones contemporáneas enlazando la clínica y los discursos de época
