Abstract
OBJECTIVE Inflammation markers, e.g. C- reactive protein (CRP) and sedimentation rate, can be normal despite active vasculitis. Von Willebrand factor (vWF) is secreted from endothelial cells in response to vascular damage. Some reports suggest increased vWF levels in vasculitis. This study aimed to evaluate vWF serum concentration in vasculitis patients as a possible biomarker of disease activity and to review the current literature. METHOD Adult patients with systemic vasculitis were prospectively enrolled. Disease activity was recorded using the Birmingham Vasculitis Activity Score (BVAS) version 3. Blood group-adjusted vWF antigen serum level was evaluated at diagnosis and, when available, after treatment. RESULTS Twenty-five vasculitis patients were compared to 15 healthy controls. The mean age of patients was 56 ± 17 years and 56% were women. Forty percent had anti-neutrophil cytoplasmic autoantibody-associated vasculitis, 20% giant cell arteritis, 16% polyarteritis nodosa, 8% Takayasu arteritis, and the rest had other vasculitides. The mean disease duration was 3.4 ± 4.8 years. Mean vWF was higher in patients with active vasculitis than in healthy controls (212 ± 81% vs 106 ± 26%, p < 0.001). vWF levels directly correlated with BVAS. In 13 patients with active vasculitis who reached remission or low disease activity after treatment, vWF level at follow-up decreased significantly. In three out of five patients who were treated with interleukin-6 inhibitors, vWF was elevated despite normal CRP levels, while vasculitis was clinically active. CONCLUSION vWF antigen serum level is increased in active vasculitis and could potentially serve as a biomarker for active disease.

Abstract
Elimination disorders are common in children, and numerous psychosocial treatments for pediatric enuresis and encopresis are available to guide clinicians. However, only five cases of functional elimination disorders in adults are published to date, all of which involve severe comorbid psychopathology, and no treatment guidelines for adult elimination disorders exist. This case report presents, to our knowledge, the first documented case of functional elimination disorder in an otherwise healthy, high-functioning adult. “Ben” is a 20-year-old male who sought treatment for chronic enuresis and encopresis, as well as difficulties with procrastination of schoolwork. Ben engaged in 21 weeks of cognitive behavioral therapy and reported substantial decreases in elimination disorder symptoms. However, improvements fluctuated throughout treatment and remained present at mild levels at 3-month follow-up. This report outlines the cognitive behavioral interventions applied throughout this treatment, which consisted of pediatric elimination disorder interventions adapted for an adult with additional cognitive behavioral tools.

Abstract
Abstract
Background
The optimal method for balloon-expandable transcatheter heart valve (THV) deployment remains unknown. Current implantation protocols are volume-dependent and rely on ad-hoc filling of the deployment apparatus without accounting for annular wall tension during prosthesis expansion, predisposing patients to inconsistent clinical outcomes. During THV deployment, the annular wall tension exerted by the expanding prosthesis is determined by prosthesis diameter and balloon pressure (Laplace's Law).
Objective
We proposed and tested a novel method for balloon-expandable THV deployment, aimed at controlling balloon pressure and the resulting annular wall tension to allow optimal prosthesis-annulus apposition while preventing significant tissue injury.
Methods
330 consecutive patients with severe native aortic stenosis who underwent balloon-expandable THV implantation between 2015–2020 were included. 106 patients were considered high-risk for annular rupture. THVs were deployed until reaching a pre-determined balloon pressure; 4–4.5atm in earlier cases to establish experience and safety, later increasing to 5–6.5atm in most cases. Post-dilatation was performed to reduce >mild angiographic regurgitation (PVR). Using a biomechanical model, annular wall stress (tension) was estimated for each case and assessed against recorded rates of post-dilatation, ≥mild paravalvular regurgitation (PVR) on TTE, new PPM or LBBB and annular rupture.
Results
Patients with wall stress >3MPa (n=184) had reduced post-dilatation rate (p<0.001) and final PVR (≥mild, p=0.014). Annular rupture occurred in 2/3 high-risk cases with wall stress >3.5MPa; no rupture occurred in 102 high-risk cases with wall stress ≤3.5MPa. Based on these results, we defined target deployment wall stress levels (3–3.5MPa) and associated deployment pressure per THV size. Patients within this target range (n=136) had 8.1% new PPM, 12.5% new LBBB, 12.7% mild PVR with no cases of ≥moderate PVR. Importantly, there was an inconsistent relationship between deployment balloon volume and resulting annular wall stress.
Conclusion
Pressure-regulated THV deployment is a simple, easily reproducible, safe and effective method, regardless of high-risk anatomical complexities.

Abstract
Abstract
Background
The prevalence and outcomes of low-gradient severe aortic stenosis (AS), in particular low-flow low-gradient (LFLG) severe AS, have not been well characterized.
Objectives
We sought to delineate the relative prevalence and outcomes of patients with low-gradient severe AS in routine clinical cardiology practice.
Methods
Data were derived from the National Echocardiography Database of Australia (NEDA), a national multicentre clinical registry with data linkage to mortality. A total of 192,060 adults with native aortic valve profiling from 2000–2019 were identified, of whom 12,013 (6.3%) had severe AS (aged 75.3±13.1 years, 53.5% men). Severe AS subtypes were determined using standard echocardiographic criteria. All-cause and cardiovascular-related mortality were assessed on an adjusted basis (age and sex) in 8,162 patients with classifiable severe AS subtypes, during mean follow-up of 88±45 months. Additionally, rates of recorded Aortic Valve Replacement (AVR) during follow-up were compared between AS groups.
Results
5,601 patients (47%) had high-gradient and 6,412 patients (53%) had low-gradient severe AS. In the low-gradient group, Stroke Volume Index data was recorded in 2,741 patients; 1,750 (64%) had LFLG and 991 (36%) had normal-flow low-gradient (NFLG). For LFLG patients, 1,570 had LV ejection fraction recorded; 959 (61%) had paradoxical LFLG and 651 (39%) had classical LFLG. Adjusted 5-year cardiovascular mortality rates were 28% in high-gradient, 24% in NFLG, 27% in paradoxical LFLG and 50% in classical LFLG patients (p<0.001). Rates of recorded AVR per mean follow-up years were 5.2% for high-gradient, 4.0% for NFLG, 3.1% for classical LFLG and 2.4% for paradoxical LFLG severe AS (p<0.001).
Conclusions
Approximately half the subjects with echocardiographic features of severe AS in routine clinical practice have low-gradient haemodynamics, associated with long-term mortality comparable to or worse than high-gradient severe AS. The poorest survival was associated with classical LFLG severe AS.

Abstract
Abstract
Introduction
There are currently no established prognostic models for low-flow, low-Gradient (LFLG) severe aortic stenosis (AS). The Cardiac Damage Staging Classification, has been validated as a clinically useful prognostic tool in high-gradient severe AS, but not specifically in LFLG severe AS.
Objective
To assess and confirm the prognostic utility of the Cardiac Damage Staging Classification, in LFLG severe AS patients.
Methods
We analysed data from the National Echocardiography Database of Australia (NEDA), a national multicentre registry with individual data linkage to mortality. Of 192,060 adults (aged 62.8±17.8 years) with comprehensive ultrasound profiling of the native aortic valve studied between 2000–2019, 12,013 (6.3%) had severe AS. Based on standard echocardiographic parameters, 611 classical and 959 paradoxical LFLG patients were identified. Mean follow-up was 70±41 months. All-cause and cardiovascular-related mortality were assessed for each LFLG group on an adjusted basis (age and sex), according to cardiac damage classification staging.
Results
Paradoxical LFLG patients were younger (mean age 74.3 vs 76.2, p=0.006) and more often female (62.8% vs 36.3%, p<0.001). Classical LFLG patients had greater associated cardiac damage at diagnosis (76% vs. 49%, for Stage ≥2, p<0.001). Compared to Stage 0 paradoxical LFLG patients, adjusted 1- and 5-year cardiovascular-related mortality was 200% (HR 2.82, 95% CI 1.12–7.11) and 120% (HR 2.42, 95% CI 1.46–4.02) higher in Stage 2 patients and 350% (HR 4.23, 95% CI 1.68–10.63) and 175% (HR 3.18, 95% CI 1.90–5.34) higher in Stage 3/4 patients, respectively. Compared to Stage 1 classical LFLG patients, adjusted 1- and 5-year cardiovascular-related mortality was 58% (HR 1.66, 95% CI 0.95–2.90) and 24% (HR 1.35, 95% CI 0.91–1.99) higher in Stage 2 patients and 125% (HR 2.48, 95% CI 1.43–4.28) and 52% (HR 1.87, 95% CI 1.26–2.78) higher in Stage 3/4 patients, respectively.
Conclusion
In patients with LFLG severe AS identified by echocardiography, increasing severity denoted by the cardiac damage staging classification is strongly associated with increasing medium- to long-term mortality.

Abstract
Abstract
Background
Conventionally, stroke volume index (SVI) ≤35ml/m2 is considered as “low-flow” in severe aortic stenosis (AS). Recent evidence suggests a lower threshold SVI (30ml/m2) may be more prognostically informative.
Objectives
To assess the association between SVI and survival in patients with low-gradient severe AS, with either preserved (LVEF ≥50%) or reduced (LVEF<50%) ejection fraction.
Methods
Data were derived from the National Echocardiography Database of Australia (NEDA). Of 192,060 adults (aged 62.8±17.8 years) with comprehensive aortic valve profiling between 2000–2019, 12,013 (6.3%) had severe AS. Based on standard echocardiographic parameters, 1,623 patients had severe low-gradient AS with preserved LVEF and 744 patients had severe low-gradient AS with reduced LVEF. All-cause and cardiovascular-related mortality were assessed for each low-gradient group on an adjusted basis (age, sex, BMI, AVA indexed and RVSP), according to SVI. Mean follow-up was 81±42 months.
Results
Compared to patients with “normal” flow (SVI >35ml/m2), those with “low-flow” (SVI ≤35ml/m2) had significantly higher BMI, smaller AVA index and lower AV mean gradient and peak velocity (p≤0.001). In low-gradient with preserved LVEF patients, adjusted survival at 1- and 3-years was significantly lower only for SVI ≤30ml/m2 compared with SVI>35ml/m2 (p<0.001 and p<0.03, respectively). In low-gradient with reduced LVEF patients, adjusted survival at 1- and 3-years was significantly lower for SVI ≤35ml/m2 compared with SVI>35ml/m2 (p=0.015 and p=0.018, respectively).
Conclusions
Taken together with previous data, our results suggest that a SVI threshold of ≤30ml/m2 (rather than ≤35 ml/m2) is prognostically significant in severe low-gradient AS with preserved LVEF.

Abstract
Abstract
Background
Annular rupture is a catastrophic complication of Transcatheter Aortic Valve Implantation, more commonly seen with balloon expandable valves. Size selection and deployment of these valves often presents a serious challenge as prosthesis oversizing increases the risk of rupture, while undersizing results in greater paravalvular regurgitation (PVR). Current deployment protocols are volume-regulated and susceptible to undesired prosthesis over or under-expansion. Laplace's Law demonstrates that the stress exerted on the aortic wall is determined by both the valve area and internal pressure during deployment. Yet the issue of balloon pressure during deployment has been thus far ignored.
Purpose
In this feasibility study, we aimed to develop a novel pressure-regulated deployment method that allows optimising apposition between valve and annulus, while preventing significant tissue injury and rupture.
Methods
We analysed a cohort of 278 consecutive patients with severe aortic stenosis and intermediate-severe surgical risk who underwent TAVI using Sapien 3 valves. This included 88 patients (32%) considered at high risk of annular rupture based on accepted factors such as moderate-severe subannular calcification. A pressure gauge was connected to the apparatus and in each case the valve was deployed until reaching a pre-determined pressure limit. In earlier cases lower pressures of 4–4.5atm were used to establish safety, while in later cases pressure limit was increased to maximum of 7atm. In some patients post-dilatation was performed to improve angiographic regurgitation. Using a biomechanical application of Laplace's Law, the estimated annular wall stress was calculated for each case and assessed against recorded complications such as annular rupture, PPM insertion, new LBBB and PVR on post-procedure TTE. Based on these analyses we then determined the optimal pressure limit for each available valve size.
Results
Distribution of deployment pressures and associated estimated wall stress are shown in attached Figure. 1 case of annular rupture (0.4%) occurred in high risk patient at 3.81MPa. Wall stress levels >3.0MPa were associated with reduced rates of post dilatation (13% vs 37%, p<0.001) and ≥mild PVR (10.7% vs 20%, p=0.093). In patients (148) with estimated wall stress between 3–3.8MPa rates of new PPM and LBBB were 7.4% and 8.1%, respectively. Greater wall stress was not associated with increased new PPM/LBBB risk. Therefore, we suggest the optimal deployment pressure limit to minimise risk of rupture, rates of post-dilatation and clinically significant PVR is: 6atm for 23mm valves, 5.5atm for 26mm valves and 5atm for 29mm valves.
Conclusion
Pressure-regulated deployment strategy is a reproducible, safe and effective method for balloon expandable TAVI, alleviating concerns of valve oversizing in high risk patients. Further trials are needed to validate this novel method and compare it with current volume-regulated techniques.

Abstract
PURPOSE The aim of this study was to investigate the predictive value of early changes in depression levels during inpatient treatment of adolescent anorexia nervosa (AN). METHODS Fifty-six adolescents (88% girls) aged 10-18 years (M = 15.35, SD = 2.23) diagnosed with AN were assessed at admission and 1 month following admission to an inpatient setting. Depression levels and eating disorder symptoms were reported at both assessments. Re-hospitalization within 12 months of discharge was documented using official national records. RESULTS Whereas depression levels at baseline were found equivalent between subsequently re-hospitalized and non-re-hospitalized patients, at 1 month after admission patients who were later re-hospitalized had higher levels of depression compared to those who were not re-hospitalized. These differences remained significant after controlling for weight gain and anti-depressant medication intake. We additionally found that the proportion of boys in the non-re-hospitalized group was substantially larger than their proportion in the re-hospitalized group. CONCLUSIONS Our results suggest that depression at the point of hospital admission may not be a reliable predictor of treatment outcomes, and highlight the risk of relapse in AN patients whose depression levels do not alleviate after a month of inpatient treatment. Clinicians should consider providing more adjusted and intensive attention to such patients in their efforts to facilitate remission. LEVEL OF EVIDENCE III Well-designed cohort study.

Abstract
BACKGROUND Predictions of two different models for suicide attempts (SA) over 12 months, as differentially impacted by specific school-based suicide prevention interventions, were compared. These were as follows: (a) interpersonal theory (IPTS) and (b) a two-pathway model, one path associated with externalizing symptoms and continuum of self-harm behaviors, and the other with internalizing symptoms. METHODS Self-report questionnaires were completed by 11,110 high school students from ten EU countries enrolled in the Saving and Empowering Young Lives in Europe (SEYLE) study. Baseline measures included perceived burdensomeness, thwarted belongingness from parents and peers, health risk behaviors, self-injury, suicide ideation (SI), and attempts (SA). SI and SA were reassessed at 12-month follow-up. Each model's predictions of SI and SA groups over time (i.e., repeated SA, remitted SA, SA onset, and no SA) were estimated in the no intervention/control group. The superior model was estimated across intervention groups. RESULTS Interpersonal theory showed better fit compared to the two-pathway model. In partial agreement with IPTS predictions, parental low belongingness but not peer belongingness or burdensomeness predicted greater likelihood of SI. The likelihood of repeated SA versus no SA was higher among adolescents who reported SI, self-injury, risk behaviors, and particularly both SI and self-injury. All three interventions attenuated the combined effect of SI and self-injury. Youth Aware of Mental Health Program (YAM) additionally decreased the effect of risk behaviors on the likelihood of repeated SA. CONCLUSIONS Interpersonal theory assumptions were partially supported. Perceived interpersonal difficulties with parents were primarily related with SI, and risk behaviors and self-injury were important predictors of SA. Suicide prevention interventions may be effective by mitigating the hazardous effect of varying self-harm behaviors and may be further advanced by increasing parental involvement.

Abstract
BACKGROUND Self-injurious behaviors in adolescence are a serious public health concern. AIMS The current study aims to expand our understanding of motives for direct self-injurious behaviors (D-SIB). We examined the explicit motives but also the actual antecedents and consequences of D-SIB over time. METHOD As part of the Saving and Empowering Young Lives in Europe (SEYLE) study, adolescents between the ages of 14 and 18 years from Israel completed self-report questionnaires at baseline, 3-month, and 12-month follow-ups. RESULTS Decreases in social support predicted later increases in D-SIB, an effect mediated by negative affect. Both peer and parental support also exerted quadratic effects on D-SIB. Thus, low as well as high support predicted subsequent D-SIB. In turn, D-SIB was followed by increased peer and parental support. LIMITATIONS Our methodology relies on self-reports, affected by social desirability and recall biases. CONCLUSION The findings support a causal path for the development of D-SIB: from interpersonal distress to emotional distress and then to D-SIB. They also point to interesting avenues regarding subgroupings of adolescents who self-injure depending on their motives. Finally, our results reveal that D-SIB, although of negative import, might paradoxically be effective in serving certain functions such as gaining support from parents and peers.

Abstract
Inspired by the two-stage model of countervailing forces, we explored the mechanism underlining inward and outward aggression among ex-combatants. Israeli veterans (N = 230) reported their partner's violence (outward aggression), suicidal ideation (inward aggression), aggressive impulses, posttraumatic stress disorder (PTSD), paranoid ideation and guilt. Suicidal ideation was related to aggressive impulses only in the presence of PTSD, or under high guilt; whereas paranoid ideation buffered these effects. Violence towards the partner, on the other hand, was related to aggressive impulses under low guilt and in the absence of PTSD. Aggressive impulses underline both suicidal ideation and partner violence. The inter-relations between PTSD, guilt, and paranoid ideation influence the manifestation of aggression and the direction it takes.

Abstract
Combat stress reaction (CSR) has widespread long-term consequences, including profound psychopathology in the form of posttraumatic stress disorder (PTSD). Studies have established the link between combat, PTSD, and suicidality. However, little is known about the temporal course of suicidal ideation (SI) in general, specifically among war veterans. We aimed to trace the trajectories of SI in the aftermath of war and to explore the role of CSR and PTSD in SI trajectories. Israeli veterans with CSR (n=164) and a matched control group (NCSR, n=111) were assessed, using self-report measures at three points over the course of 20 years. Veterans with CSR reported significantly higher levels of SI, compared to the NCSR group at all measurement points. Among veterans with CSR, SI increased 2 years after the war and then decreased 20 years following the war. This pattern was particularly characteristic of veterans with chronic PTSD. The results indicate that CSR is a strong predictor of subsequent PTSD and suicidality. These findings highlight the importance of prevention and treatment efforts for these traumatized veterans, who are at risk for suicide even 20 years after the end of the war.

Abstract
Previous studies have examined the association between victimization by bullying and both suicide ideation and suicide attempts. The current study examined the association between victimization by bullying and direct-self-injurious behavior (D-SIB) among a large representative sample of male and female adolescents in Europe. This study is part of the Saving and Empowering Young Lives in Europe (SEYLE) study and includes 168 schools, with 11,110 students (mean age = 14.9, SD = 0.89). Students were administered a self-report survey within the classroom, in which they were asked about three types of victimization by bullying (physical, verbal and relational) as well as direct self-injurious behavior (D-SIB). Additional risk factors (symptoms of depression and anxiety, suicide ideation, suicide attempts, loneliness, alcohol consumption, drug consumption), and protective factors (parent support, peer support, pro-social behavior) were included. The three types of victimization examined were associated with D-SIB. Examination of gender as moderator of the association between victimization (relational, verbal, and physical) and D-SIB yielded no significant results. As for the risk factors, depression, but not anxiety, partially mediated the effect of relational victimization and verbal victimization on D-SIB. As for the protective factors, students with parent and peer support and those with pro-social behaviors were at significantly lower risk of engaging in D-SIB after being victimized compared to students without support/pro-social behaviors. This large-scale study has clearly demonstrated the cross-sectional association between specific types of victimization with self-injurious behavior among adolescents and what may be part of the risk and protective factors in this complex association.

Abstract
The current study's main goal was to examine whether affective instability is elevated among individuals suffering from avoidant personality disorder (APD) by comparing it to the affective instability found among individuals suffering from borderline personality disorder (BPD) as well that found among healthy controls. Adults (N = 152, aged 18-65 years) with BPD, APD, or no psychopathology participated in a 3-week computerized diary study. We examined temporal instability in negative affect using experience-sampling methods. Both within and between days, individuals with APD showed greater affective instability compared to the healthy control individuals, although less affective instability compared to individuals with BPD. The findings are in line with affective instability (or emotional lability) as a key dimension relevant across personality disorders. Additionally, they emphasize the need for research and clinical attention to affective characteristics (alongside the more readily recognized interpersonal characteristics) of APD.

Abstract
BACKGROUND Joiner's interpersonal theory of suicide (IPTS) proposes that suicide results from the combination of a perception of burdening others, social alienation, and the capability for self-harm. The theory gained some empirical support, however the overall model has yet to be tested. This study aimed to test the main predictions of IPTS in a large community sample of Israeli adolescents. METHOD 1196 Israeli Jewish and Arab high-school pupils participating in the SEYLE project completed a self-report questionnaire measuring perceived burdensomeness, thwarted belongingness, health risk behaviors, and non-suicidal self-injury (risk variables), and suicidal ideation and suicide attempts (outcome measures). The data were tested in cross-sectional regression models. RESULTS Consistent with IPTS, perceived burdensomeness was found to interact with thwarted belongingness, predicting suicidal ideation. Depression mediated most of the effect of thwarted belongingness and perceived burdensomeness on suicidal ideation. Acquired capability for self-harm, as measured by health risk behaviors and direct non-suicidal self-injurious behaviors, predicted suicide attempt. However, this mechanism operated independently from ideation rather than in interaction with it, at variance with IPTS-based predictions. LIMITATIONS The cross-sectional design precludes conclusions about causality and directionality. Proxy measures were used to test the interpersonal theory constructs. CONCLUSION The findings support some of the IPTS predictions but not all, and imply two separate pathways for suicidal behavior in adolescents: one related to internalizing psychopathology and the other to self-harm behaviors. This conceptualization has clinical implications for the differential identification of adolescents at risk for suicidal behavior and for the development of prevention strategies.

Abstract
Nonsuicidal self-injury (NSSI) is a perplexing phenomenon that may have differing motives. The present study used experience sampling methods (ESM) which inquired explicitly about the motives for NSSI, but also enabled a temporal examination of the antecedents/consequences of NSSI; these allow us to infer other motives which were not explicitly endorsed. Adults (n = 152, aged 18-65) with borderline personality disorder (BPD), avoidant personality disorder (APD), or no psychopathology participated in a 3-week computerized diary study. We examined 5 classes of explicit motives for engaging in NSSI, finding support primarily for internally directed rather than interpersonally directed ones. We then used multilevel regression to examine changes in affect, cognition, and behavior surrounding moments of NSSI acts/urges compared with control moments (i.e., without NSSI). We examined changes in 5 scales of inferred motives, designed to correspond to the 5 classes of explicit motives. The results highlight differing motives for NSSI among individuals with BPD and APD, with some similarities (mostly in the explicit motives) and some differences (mostly in the inferred motives) between the disorders. Despite their infrequent explicit endorsement, fluctuations in interpersonally oriented scales were found surrounding NSSI acts/urges. This highlights the need to continue attending to interpersonal aspects of NSSI in research and in clinical practice. Additionally, NSSI urges, like acts, were followed by decline in affective/interpersonal distress (although in a delayed manner). Thus, interventions that build distress tolerance and enhance awareness for affective changes, and for antecedent/consequence patterns in NSSI, could help individuals resist the urge to self-injure.

Abstract
Social proximity typically helps individuals meet their belongingness needs, but several forms of psychopathology, including borderline and avoidant personality disorders (BPD and APD, respectively) are characterized by social difficulties. This experience-sampling study is one of the first to directly investigate the affective reactions of individuals with BPD and APD (compared with healthy controls [HC]) to social proximity in daily life. We examined both person-level and day-level reactions. At the person level, the rate of social proximity across the diary period was associated with diminished feelings of rejection, isolation, shame, and dissociation in the HC group. In contrast, it was not associated with any affective reaction in the BPD group, and was associated with decreased rejection and isolation on the one hand, but also with increased anxiety in the APD group. At the day level, we used multilevel regression to examine affective reactions when in social proximity. The HC group showed a consistent benefit when in social proximity. In contrast, both PD groups exhibited mixed affective reactions to social proximity; specifically, benefits (increased positive affect, decreased rejection, isolation, and dissociation) were interspersed with costs (increased shame for both PD groups; increased anger for BPD; increased anxiety for APD). The mixed reactions found in both PDs may contribute to the disturbed relationships of individuals with these disorders.

Abstract
Rising global rates of pathological Internet use (PIU) and related psychological impairments have gained considerable attention in recent years. In an effort to acquire evidence-based knowledge of this relationship, the main objective of this study was to investigate the association between PIU, psychopathology and self-destructive behaviours among school-based adolescents in eleven European countries. This cross-sectional study was implemented within the framework of the European Union project: Saving and Empowering Young Lives in Europe. A representative sample of 11,356 school-based adolescents (M/F: 4,856/6,500; mean age: 14.9) was included in the analyses. PIU was assessed using the Young's Diagnostic Questionnaire. Psychopathology was measured using the Beck Depression Inventory-II, Zung Self-Rating Anxiety Scale and Strengths and Difficulties Questionnaire. Self-destructive behaviours were evaluated by the Deliberate Self-Harm Inventory and Paykel Suicide Scale. Results showed that suicidal behaviours (suicidal ideation and suicide attempts), depression, anxiety, conduct problems and hyperactivity/inattention were significant and independent predictors of PIU. The correlation between PIU, conduct problems and hyperactivity/inattention was stronger among females, while the link between PIU and symptoms of depression, anxiety and peer relationship problems was stronger among males. The association between PIU, psychopathology and self-destructive behaviours was stronger in countries with a higher prevalence of PIU and suicide rates. These findings ascertain that psychopathology and suicidal behaviours are strongly related to PIU. This association is significantly influenced by gender and country suggesting socio-cultural influences. At the clinical and public health levels, targeting PIU among adolescents in the early stages could potentially lead to improvements of psychological well-being and a reduction of suicidal behaviours.

Abstract
BACKGROUND Subthreshold-depression and anxiety have been associated with significant impairments in adults. This study investigates the characteristics of adolescent subthreshold-depression and anxiety with a focus on suicidality, using both categorical and dimensional diagnostic models. METHODS Data were drawn from the Saving and Empowering Young Lives in Europe (SEYLE) study, comprising 12,395 adolescents from 11 countries. Based on self-report, including Beck Depression Inventory-II (BDI-II), Zung Self-Rating Anxiety Scale (SAS), Strengths and Difficulties Questionnaire (SDQ) and Paykel Suicide Scale (PSS) were administered to students. Based on BDI-II, adolescents were divided into three groups: nondepressed, subthreshold-depressed and depressed; based on the SAS, they were divided into nonanxiety, subthreshold-anxiety and anxiety groups. Analyses of Covariance were conducted on SDQ scores to explore psychopathology of the defined groups. Logistic regression analyses were conducted to explore the relationships between functional impairments, suicidality and subthreshold and full syndromes. RESULTS Thirty-two percent of the adolescents were subthreshold-anxious and 5.8% anxious, 29.2% subthreshold-depressed and 10.5% depressed, with high comorbidity. Mean scores of SDQ of subthreshold-depressed/anxious were significantly higher than the mean scores of the nondepressed/nonanxious groups and significantly lower than those of the depressed/anxious groups. Both subthreshold and threshold-anxiety and depression were related to functional impairment and suicidality. CONCLUSIONS Subthreshold-depression and subthreshold-anxiety are associated with an increased burden of disease and suicide risk. These results highlight the importance of early identification of adolescent subthreshold-depression and anxiety to minimize suicide. Incorporating these subthreshold disorders into a diagnosis could provide a bridge between categorical and dimensional diagnostic models.

Abstract
We aim to investigate the additive value of B cell-activating factor (BAFF) when added to oligodeoxynucleotides (ODN)-activated B cells with respect to TLR-9, CD69, MHC-II expression, IL-6 and IL-10 secretion and B cell cycling. Therefore, B cells from healthy individuals were incubated under the following conditions: (1) B cells with medium, (2) B cells with ODN 0.5 μm, (3) B cells with BAFF 20 μm and (4) B cells with both ODN 0.5 μm and BAFF 20 μm. We found that addition of BAFF did not enhance the expression of TLR-9, CD69 and MHC-II in ODN-activated B cells. Incubation of B cells with BAFF and ODN together leads to a marked elevation of IL-6 and IL-10 levels compared to ODN alone. Synthesis and mitosis were higher in B cells stimulated by BAFF than in B cells stimulated by ODN. These findings suggest that both BAFF and TLR-9 contribute independently to B cell function.

Abstract
BACKGROUND IL-6 mediated inflammation is induced by binding to IL-6 receptor (IL-6R) or IL-6/IL-6R complex binding gp130. Tocilizumab, a recombinant humanised monoclonal antibody that acts as IL-6R antagonist has been recently introduced for the treatment of rheumatoid arthritis (RA). OBJECTIVES To evaluate whether tocilizumab therapy may induce B cells to undergo phenotypic changes compatible with regulatory function. METHODS B cells from treated RA patients were isolated before and after 3 months of treatment with tocilizumab and were stained for the expression of intracellular TGF-β, IL-10, membrane CD69, and MHCII. These markers were assessed in CD25(high) B cells considered to belong to a regulatory/suppressive subset of B cells. All markers were expressed in mean flow cytometry intensity (MFI), with results given in mean ± SEM. Data was compared before and after tocilizumab treatment. RESULTS Clinical improvement was noted three months following the initiation of tocilizumab, namely: DAS improvement from 6.8 ± 0.3 at baseline to 3.1 ± 0.4, p<0.002, and ESR decrease from 44.4 ± 8.6 at baseline to 7.4 ± 2.3, p<0.006. This clinical benefit was found to occur in association with the expansion of a B cell subset with regulatory properties namely: the expression of intracellular TGF-β in CD25-high B cells was significantly increased (from 5.2 ± 2.3 at baseline to 8.1 ± 2.8; p<0.02); In addition, the expression of MHC-II and of CD69 on B cells were significantly reduced (from 9.1 ± 2.2 at baseline to 4.2 ± 0.4; p<0.04), and (from 7.6 ± 2.4 at baseline to 2.7 ± 0.7; p<0.03) respectively. CONCLUSIONS The present finding of a shift in B cell properties following tocilizumab treatment, namely the increase in TGF-β expression and the alteration in the activation status (CD69 expression) and APC properties (MHC-II expression) in CD25(high) B cells, suggests that the induction/expansion of B regulatory cells may be one of the mechanisms by which tocilizumab may possibly produce its beneficial clinical effects.
