Tension and disordered eating behaviors in the daily lives of adolescents and young adults from the general population: Associations and moderating role of trait emotion regulation

Experiences of tension and difficulties in emotion regulation have been linked to eating pathology in clinical samples and are targeted in respective treatment approaches. The present study aimed to investigate the impact of tension on engagement in disordered eating behaviors (DEBs) and potential moderating effects of trait emotion regulation in young people from the general population. A subsample of 971 adolescents and young adults from an epidemiological cohort study reported on levels of tension and four different DEBs (skipping eating, restrained eating, eating large amounts of food, loss-of-control-eating) via ecological momentary assessment (EMA), as well as on trait emotion regulation via questionnaire. In multilevel models, momentary tension did not predict levels of subsequent DEBs. However, higher average levels of tension across the EMA period predicted higher levels of all DEBs. No interactions with emotion regulation emerged. Individuals experiencing overall higher levels of tension appear to be more prone to engaging in DEBs.

Sociodemographic, psychological, and clinical characteristics associated with health service (non-)use for mental disorders in adolescents and young adults from the general population

Most adolescents and young adults who experience psychological distress do not seek professional help. This study aims to enhance the understanding of sociodemographic, psychological, and clinical characteristics associated with the underuse of health services by adolescents and young adults with mental disorders. Data from a cross-sectional, epidemiological study with a population-based sample (N = 1180 participants, 14-21 years old) were used. Participants completed a fully standardized, computer-assisted diagnostic interview (DIA-X-5/D-CIDI) administered by trained clinical interviewers to assess lifetime mental disorders according to DSM-5 as well as lifetime health service use for mental health problems, and completed self-report questionnaires to assess various psychological variables (e.g., stigma). Predictors of health service use were examined using univariate and multiple logistic regression analyses, data were weighted for age and sex to improve representativeness Of n = 597 participants with any lifetime mental disorder, 32.4% [95% CI 28.4; 36.7] had ever used any health services because of a mental health, psychosomatic, or substance use problem. Even less had received psychotherapeutic or pharmacological treatment (Cognitive Behavioral Therapy: 12.1% [9.5; 15.2]; other psychotherapy: 10.7% [8.4; 13.7]; medication: 5.4% [3.7; 7.8]). High education was associated with less health service use (low/ middle/ other vs. high education: 53.8% vs. 26.9%; OR = 0.26, p < .001). In the multiple regression model, stigma toward mental disorders was the single psychological variable associated with a reduced likelihood of using health services (OR = 0.69 [0.52; 0.90], p < .01). These findings draw attention to the treatment gap for mental disorders during adolescence and highlight related factors to be addressed in public health contexts.

Rotation of liquid-preserved artificial insemination doses on roller benches affects sperm quality during storage in stallions

Appropriate stallion semen handling is of great importance in equine artificial insemination (AI) industry. Optimal treatment of AI doses is aiming for best sperm preservation by excluding strong environmental influences and adding media that favour sperm survival. One method widely used in stallion sperm handling is the rotation of liquid-preserved semen samples on roller benches during storage. As previous studies in boars give rise to the fact that rotation should not be considered beneficial for spermatozoa anymore, the present study investigated the influence of continuous rotation of diluted stallion AI portions on sperm quality. Ejaculates (n = 15) were collected at a German AI centre and diluted with the two extenders EquiPlus and Gent (Minitüb GmbH) to a final concentration of 50 × 106  sperm/mL. Afterwards, samples were placed separately on roller benches at 5°C in the dark, obtaining a rotation frequency of 5 revolutions per minute (rpm) and 36 rpm for four consecutive days following a split-sample design. Both groups were analysed daily in comparison to a control group (0 rpm) with an extended spectrum of spermatological methods including computer-assisted sperm analysis and flow cytometry. Statistical analyses were based on the calculation of generalized linear mixed models for each sperm parameter. The research revealed a decrease in sperm quality parameters of rotated samples compared to non-rotated control groups, visible in total sperm motility (p < .001), decreased thermo-resistance (p < .01) and a drop in pH (p < .001). Interestingly, no differences (p > .05) were detected between rotation frequencies of 5 and 36 rpm. We conclude that the fertilizing capacity of stallion semen was negatively affected by rotation during storage in vitro, irrespective of the rotation frequency. Further studies need to investigate whether field fertility in horses is similarly affected by semen rotation on roller benches in vivo.

Assessment of the stallion sperm acrosome in two different extenders: Spermac stain in comparison with PNA/PSA/PI triple-staining

Since the stallion acrosome is very small compared to other species and cannot be properly assessed without additional staining, several labelling techniques were developed to facilitate its assessment. The aim of this study was to compare the Spermac stain (Minitüb GmbH) and a PNA/PSA/PI triple-staining detected by flow cytometry with regard to method agreement for detecting non-intact acrosomes within two different extenders. For this purpose, eighteen stallion ejaculates were split in half and diluted with the semen extenders EquiPlus or Gent (Minitüb GmbH) to a final concentration of 50 × 106  sperm/mL, respectively. Subsequently, 126 semen samples were stained with both methods between 4 and 240 h (mean: 63.8 ± 48.9 h) after semen collection. Calculated Intraclass correlation coefficients revealed excellent correlations between both methods for EquiPlus (r = .77, p < .001) and fair correlations for Gent (r = .49, p < .001). Interestingly, flow cytometry detected more non-intact acrosomes in EquiPlus than in Gent (p < .001), whereas the Spermac stain showed no differences (p = .902) between extenders. The poorer method agreement in Gent could be caused by egg yolk artefacts, which made interpretation difficult, so flow cytometry might be preferred. The differences in detected non-intact acrosomes between extenders highlighted the importance of establishing adapted laboratory protocols for different extender types in order to generate comparable results.

Hair androgen concentrations and depressive disorders in adolescents from the general population

Although the link between androgens and depression is well established in adults, the effects of cofactors on this association are less clearly understood, particularly in youth. Epidemiological cohort study of adolescents in Dresden, Germany. Analyses comprised data of 985 individuals assessed at baseline and of 512 individuals at 1-year follow-up. We investigated multivariable regression models for cross-sectional and longitudinal associations of hair testosterone, dehydroepiandrosterone (DHEA), and their cortisol ratios with 12-month diagnoses of major depressive disorder (MDD) and MDD without any anxiety disorder assessed with standardized diagnostic interview (DIA-X-5), and with dimensional depression scores (PHQ-9, PROMIS), separately for males and females. The potential moderating effect of social support was determined. Cross-sectional analyses yielded inverse associations of testosterone and DHEA with MDD and MDD without any anxiety disorders in males. In cross-sectional and longitudinal analyses, baseline ratio cortisol/DHEA was significantly, inversely associated to PROMIS-depression in males. Only cross-sectional associations for ratio cortisol/DHEA and PROMIS-depression remained significant after Bonferroni-Holm correction. No robust associations were observed in female participants. Social support exerted no consistent moderating effect on the investigated association. The present observational cohort study showed no consistent association of hair androgen concentrations with depressive disorders in adolescents. However, findings provide some support for the association between the cortisol/DHEA ratio and depression in males. Longitudinal research designs in large samples are needed to understand the interplay between androgens, depression, and developmental and social factors in youth.

Ecological momentary assessment and applied relaxation: Results of a randomized indicated preventive trial in individuals at increased risk for mental disorders

Applied Relaxation (AR) is an established behavioral mental health intervention, but its efficacy in real life contexts remains unclear. Using randomized controlled trial data, we examined whether AR can effectively reduce mental health problems in daily life. A sample of 277 adults with increased psychopathological symptoms but without 12-month DSM-5 mental disorders at study entry was randomly assigned to an intervention group receiving AR training (n = 139) and an assessment-only control group (n = 138). Ecological momentary assessments were used to assess psychological outcomes in daily life over a period of seven days at baseline, post, and 12-month follow-up, respectively. Multilevel analyses indicated that all psychopathological symptoms decreased more in the intervention group than in the control group from baseline to post (range β = -0.31 for DASS-depression to β = -0.06 for PROMIS-anger). However, from post to follow-up, psychopathological symptoms decreased more in the control group than in the intervention group, so that only the intervention effects for PROMIS-depression (β = -0.10) and PROMIS-anger (β = -0.09) remained until follow-up. Moreover, positive affect (β = 0.19), internal control beliefs (β = 0.15), favorable coping (β = 0.60), and unfavorable coping (β = -0.41) improved more in the intervention group than in the control group, and these effects were mostly maintained in the long term. Some effects were stronger among women, older individuals, and individuals with higher initial symptoms. These findings suggest that AR can effectively reduce mental health problems in daily life.

Clinical aspects and targeted inspiratory muscle training in children and adolescents with Fontan circulation: a randomized controlled trial

Background

Since 1968, thousands of patients with a morphologically or functionally univentricular heart have been treated with a total cavopulmonary connection/Fontan operation. Because of the resulting passive pulmonary perfusion, blood flow is assisted by the pressure shift during respiration. Respiratory training is known to improve exercise capacity and cardiopulmonary function. However, there are limited data on whether respiratory training can also improve physical performance after Fontan surgery. The aim of the present study was to clarify the effects of six months of daily home-based inspiratory muscle training (IMT) aimed at increasing physical performance by strengthening respiratory muscles, improving lung function and peripheral oxygenation.

Methods

In this non-blinded randomized controlled trial, the effects of IMT on lung capacity and exercise capacity were measured in a large cohort of 40 Fontan patients (25% female; 12.3±2.2 years) who were under regular follow-up by the outpatient clinic of the Department of Congenital Heart Defects and Pediatric Cardiology of the German Heart Center Munich. After a lung function test and a cardiopulmonary exercise test, patients were randomly assigned in a parallel arm design to either an intervention group (IG) or a control group (CG) via stratified and computer-generated letter randomization from May 2014 to May 2015. The IG completed a daily, telephone-monitored IMT of three sets of 30 repetitions for six months with an inspiratory resistive training device (POWERbreathe medic^®), the CG continued their usual daily activities without an IMT until the second examination within the timeframe of November 2014 until November 2015.

Results

After six months of IMT, lung capacity values in the IG (n=18) did not increase significantly compared to the CG [n=19; ΔFVC: IG: 0.21±0.16 l vs. CG 0.22±0.31 l; P=0.946 (CI: -0.16, 0.17); ΔFEV1: CG: 0.14±0.30 vs. IG: 0.17±0.20 P=0.707 (CI: -0.20, 0.14)]. Exercise capacity did not improve significantly, yet the maximum workload achieved trended to improve with an increase of 14% in the IG vs. 6.5% in the CG [P=0.113 (CI: -15.8, 1.76)]. There was a significant increase of oxygen saturation at rest in the IG compared to the CG [IG: 3.31%±4.09% vs. CG: 0.17%±2.92%, P=0.014 (CI: -5.60, -0.68)]. Compared to the CG, the mean oxygen saturation at peak exercise no longer dropped below 90% in the IG. This observation is thus not statistically significant, yet of clinical relevance.

Conclusions

The results of this study show benefits of an IMT in young Fontan patients. Even if some data are not statistically significant, they may still be clinically relevant and may contribute to a multidisciplinary approach in patient care. IMT should therefore be an additional target and integrated into the training program to improve the prognosis of Fontan patients.

Dynamics of affect, cognition and behavior in a general population sample of adolescents and young adults with current and remitted anxiety disorders: An Ecological Momentary Assessment study

BACKGROUND

Measures of dynamic changes in affect/emotions (variability, instability, inertia) have been linked to anxiety disorders (AD). We examine dynamics in affect, cognition and behavior in youth with current and remitted AD.

METHODS

Mental disorders were assessed in a general population sample (N = 1180, age 14-21; Dresden, Germany) using standardized interview. Ecological Momentary Assessment of real-life affect, cognition and behavior took place eight times/day for four days.

RESULTS

Individuals with current AD (n = 65) compared to healthy controls (HC, n = 531) revealed heightened variability of anxious and manic symptomatology, experiential avoidance, optimism and positive thoughts. Remitted AD (n = 52) showed lower variability of anxious and manic symptomatology and positive thoughts compared to current AD, while no differences were found compared to HC. Current AD and HC differed significantly in instability. Remitted AD showed lower instability of all constructs except for anger than current AD, and higher instability on all constructs except for positive and negative thoughts compared to HC. Current AD showed higher inertia of anger and negative thoughts than HC, and less inertia of positive thoughts than remitted AD.

DISCUSSION

AD in youths is particularly linked to higher variability and instability of intertwined emotion-related experiences that partly persist after remission, informing emotion regulation models and interventions.

ODP029 Associations between Objective and Subjective Indicators of Stress and Sleep Disturbance in Adolescents and Young Adults from the General Population

Background

Sleep is a complex and dynamic vital state, occupying one third of human's lifetime. Disturbed sleep can be a symptom of and a risk factor for a wide range of mental disorders and somatic diseases. One pathway through which sleep problems may lead to health problems is by dysregulation of the body's physiological stress response system as indicated by aberrant cortisol. Previous findings showed that poor sleep quality and sleep disruption were associated with elevated cortisol levels in adults. Regarding adolescents, there is evidence that sleep problems are linked to hyper-reactivity to stress with effects being stronger in girls than boys. In addition, adolescence itself was associated with decreased sleep quality and an increase in perceived stress dependent on age. However, little evidence is available for the association between objective and subjective stress markers and sleep in the daily life of adolescents from the general population. The aim of this study was to examine the association between 1) cortisol and 2) subjective stress with sleep in adolescents and young adults.

Methods

We used baseline data (11/2015–12/2016) of the Behavior and Mind Health(BeMIND) study, an epidemiological study based on a random community sample of individuals aged 14 to 21 years (Dresden, Germany, N = 1,180). We assessed sleep disturbance with the short form of the PROMIS Sleep-Disturbance questionnaire (8 items) via Ecological Momentary Assessment, conducted on four days directly after awakening, calculated mean. Cortisol was measured in hair (pg/mg) and saliva (nmol/l). Cortisol awakening response and total cortisol were calculated. Subjective stress was assessed via 1) the Perceived Stress Scale (PSS), 2) the Trier Inventory of the Assessment of Chronic Stress-Screening (TICS), and 3) two items for time urgency (subjective stress in school/at work/university and leisure, self-developed). Weighted linear regressions with robust standard errors were performed after exclusions (n = 1132, 48.4% female). Models were adjusted for sex, age, pubertal development and rerun in sex-specific analyses.

Results

Mean age was 17.83 (SD 0. 07). Neither hair, nor saliva cortisol was associated with PROMIS Sleep (hair cortisol: unstandardized β-coefficient: -0. 002, 95% confidence interval (CI): -0. 012; 0. 007). All analyzed subjective stress variables were associated with PROMIS Sleep. We found positive associations between PSS (β-coefficient: 0.151, 95% CI: 0.117; 0.183), TICS (β-coefficient: 0. 056, 95% CI: 0. 045; 0. 066), and time urgency (β-coefficient: 0.114, 95% CI: 0. 061; 0.166) with sleep. There was no evidence for sex-specific effects.

Conclusion

Results confirmed the association between perceived stress and sleep in a population-based study with adolescents and young adults, that was previously shown mainly in adults. No evidence for a link between cortisol and sleep was found. Further analyses would benefit from a longitudinal perspective and consideration of mediating/moderation variables to elucidate the complex interplay between stress and sleep.

Psychosocial well-being in postpartum women with congenital heart disease

Background

Improved treatment options for congenital heart disease (CHD) lead to a growing number of women with CHD at reproductive age. Due to physical and psychological burden, pregnancies in women with CHD often count for high-risk. Resulting emotional distress can adversely impact pregnancy, motherhood and fetal health. The present study aims to retrospectively investigate mental outcomes and indices of adjustment in women with CHD before, during and after pregnancy. The novel concept of illness identity is applied to explain how patients experience and integrate their CHD into their identities.

Methods

Patient-reported outcome measures on mental functioning and illness identity were assessed in a sample of 121 postpartum women with CHD [mean age: 42.7±9.2 (range, 27-81) years] at the German Heart Centre Munich between August and November 2021 in a cross-sectional design. Descriptive analyses, correlations and linear regression models were calculated.

Results

Retrospectively assessed prevalence of emotional distress before giving birth was high (47.0%) and peaked shortly after childbirth in terms of elevated symptoms of postpartum depression and trauma. During the course of maternity, emotional distress decreased significantly (24.1%, P<0.001). Overall, postpartum women demonstrated high scores in functional illness identity states (i.e., acceptance and enrichment) and low scores in dysfunctional states (i.e., rejection and engulfment). CHD severity was not directly associated with mental outcomes (P>0.05), whereas maternal cardiovascular risk, according to the WHO classification, was significantly associated with a higher prevalence of postpartum trauma (t=2.485, P=0.015).

Conclusions

Postpartum mental health problems, such as (postpartum) depression, anxiety, and posttraumatic stress can become a serious burden which might be detrimental to the mother's well-being and her infant's development. Present findings emphasise the urgent need for a holistic approach focusing on pregnant women with CHD starting at the prepartum stage to prevent adverse consequences and promote maternal well-being. Illness identity might become an important target construct for clinical practice as it may positively and enduringly influence mental well-being of pregnant women with CHD.

Quality of life in patients with Fabry's disease: a cross-sectional study of 86 adults

Background

Fabry disease (FD) is a multi-organ disorder associated with severe physical and psychological impairments, particularly in adulthood. To date, comprehensive data on the psychological burden of FD are lacking. The present study assessed quality of life (QOL) in a representative cohort of adults with FD.

Methods

Patient-reported outcome measures were retrospectively analyzed in 86 adults with FD (49.6±16.6 years; 62.8% female) and compared to adults with congenital heart defects (ACHD) which is another lifelong disease and affliction. QOL was assessed using the European Quality of Life 5 Dimensions 5 Levels questionnaire (EQ-5D-5L).

Results

Subjects affected by FD reported an overall reduced QOL (EQ-VAS: 71.8±20.0). Most frequently reported complaints occurred within the dimensions pain/discomfort (69.7%), daily activities (48.9%) and anxiety/depression (45.4%). Compared to ACHD, individuals with FD scored significantly lower in the areas of pain/discomfort, usual activities and mobility (all P<0.05). Older age and female sex were particularly associated with diminished QOL (P=0.05).

Conclusions

Patients with FD are at high risk for impaired QOL. They require additional support to cope with disease-related challenges. Increased attention should be directed towards improving their subjective well-being to potentially increase their QOL and long-term health outcomes.

5-HTT genotype and inertia of negative affect in adolescents and young adults from the general population

The study aims to replicate the previous found association of 5-HTTLPR and inertia of negative affect in daily life of adolescents and young adults. Data of 877 adolescents (aged 14–21 years) of the Behavior and Mind Health (BeMIND) study (epidemiological cohort study, Dresden, Germany) were genotyped for 5-HTTLPR/rs25531, grouped into SS/SL_G/SL_A/L_GL_A/L_GL_G vs. L_AL_A, and provided ratings on negative affect items, depression and anxiety (Patient-Reported Outcomes Measurement Information System) eight times a day over 4 days. Multilevel regression models did not reveal an association of 5-HTTLPR genotype and inertia of negative affect, nor associations with inertia of anxiety or depression. Inertia of negative affect seems not to be a psychological mechanism through which 5-HTTLPR acts on psychopathology.

Effects of a single transdermal administration of flunixin meglumine in early postpartum Holstein Friesian dairy cows: Part 1. Inflammatory and metabolic markers, uterine health, and indicators of pain

The objectives of this study were to assess the effects of a single transdermal administration of flunixin meglumine (FM) in early postpartum Holstein Friesian dairy cows on serum concentrations of inflammatory and metabolic markers, uterine health, and indicators of pain. The hypothesis was that the anti-inflammatory, antipyretic, and analgetic effects of the pharmaceutic agent would reduce systemic inflammation, resulting in improved metabolic and inflammatory profile, diminished incidence of metritis, and reduced expression of pain. A total of 500 cows (153 primiparous, 347 multiparous) from 3 different commercial dairy farms in the northeast of Germany were included in a randomized controlled clinical trial. Farms were preselected based on high haptoglobin concentrations in their fresh lactating cows. Cows were excluded if they had experienced dystocia, stillbirth, or twin birth, or if they showed any signs of milk fever, retained fetal membranes, or fever (>40°C). The cows were treated once with either FM (3.33 mg/kg) or a placebo as control (CON) through transdermal administration between 24 to 36 h postpartum (d 2). General health examinations were performed (daily from d 2-8 and additionally on d 15 postpartum), vaginal discharge was assessed using the Metricheck device (d 8 and 15 postpartum) and serum samples were analyzed for inflammatory and metabolic markers (d 2, 4, and 6 postpartum). Effects of treatment, parity, sampling day, and their interactions were evaluated using mixed effects models. Primiparous cows treated with FM showed lower serum haptoglobin concentrations (0.90 ± 0.08 vs. 1.17 ± 0.07 g/L; ± standard error of the mean) and higher serum albumin concentrations (35.5 ± 0.31 vs. 34.8 ± 0.31 g/L) on d 6 postpartum. They also had a lower risk for purulent vaginal discharge with or without a fever compared with CON cows on d 15 postpartum (odds ratio for CON vs. FM: 1.63, 95% CI: 1.26-2.00), and body temperature was lower throughout the first 15 d in milk (39.1 ± 0.11 vs. 39.2 ± 0.11°C). Multiparous cows treated with FM had lower serum β-hydroxybutyrate concentrations on d 4 postpartum (0.71 ± 0.05 vs. 0.78 ± 0.05 mmol/L) and d 6 postpartum (0.74 ± 0.05 vs. 0.80 ± 0.05 mmol/L). Regardless of parity, FM-treated cows were significantly less likely to abduct their tail from their body (14.3 vs. 23.6%) and show an arched back (27.9 vs. 39.7%) on the day after treatment compared with CON cows. It can be concluded that FM treatment slightly reduced inflammation and diminished the risk for metritis in primiparous cows, improved metabolic profile in multiparous cows, and reduced expressions of pain in all cows.

Applied relaxation and cortisol secretion: findings from a randomized controlled indicated prevention trial in adults with stress, anxiety, or depressive symptoms

Previous research has shown that relaxation interventions can reduce distress, anxiety, and depression. The exact mechanisms that underlie the efficacy of relaxation interventions remain unresolved. This study aimed to investigate whether applied relaxation (AR) leads to changes in cortisol secretion and whether these effects mediate fewer symptoms due to AR. Data come from a randomized controlled preventive interventional trial (N = 277) with elevated tension/distress, anxiety, or depressive symptomatology. Participants were randomized to an intervention group (IG; n = 139, received AR training), or a non-interventional control group (CG, n = 138). Psychopathological symptoms were assessed with DASS-21 and diagnoses of mental disorders via DIA-X-5. Cortisol was measured as short-term index in saliva (six times/d for 2 d at pre-, post-, and follow-up [FU] assessment) and long-term index in hair samples (once at pre-assessment and FU, respectively). Data were analyzed as pre-specified secondary analyses of the randomized controlled trial (RCT) on completer basis (n = 134 CG, n = 102 IG), using multivariable-adjusted linear regression models and mediation analyses (the DASS-21 change in the IG vs. CG with cortisol (area under the curve [AUC]) as mediator). From pre- to post-assessment, total daily salivary cortisol (AUC) decreased more strongly in the IG vs. CG (β-coefficient: -13.83, 95% confidence interval [CI]: -26.85 to -0.81), but was rendered non-significant when adjusting for pre-assessment AUC. This effect was not found for the cortisol awakening response (CAR) or hair cortisol. There was no evidence for a mediation of cortisol (AUC). These findings provide little support for the idea that cortisol reductions explain the beneficial effects of AR on mental health.

Implantable loop recorder for monitoring patients with congenital heart disease

BACKGROUND

Patients with congenital heart defects (CHD) are prone to residua, sequels and complications from the underlying anomaly, where cardiac arrhythmias are one of the major causes for hospitalization, morbidity and mortality. The importance of the subcutaneous implantable loop recorder (ILR) for the detection and documentation of significant arrhythmias has increased over the last years. To date, however, there is little data on ILR use in the CHD population.

METHODS

In this single center, retrospective observational study, all CHD-patients with an ILR were identified who were under care of the German Heart Center Munich between February 2015 and January 2019. The primary endpoint of the study was the detection or exclusion of significant arrhythmias during follow-up in CHD-patients who had received an ILR. The secondary endpoint was to determine whether ILR findings influenced patient management, defined as initiation or adjustment of medication, cardioversion, electrophysiologic study, catheter ablation, or implantation of cardiac implantable electronic devices (CIEDs) such as pacemakers (PM) or implantable cardioverter-defibrillators.

RESULTS

An ILR was implanted in 33 CHD-patients (mean age, 43±20 years; 42.4% female) with CHD. During a mean observation period of 697±433 days, clinically relevant arrhythmias, correlating with the patients' complaints and symptoms, were detected in 19 patients (59.4%), encompassing supraventricular tachycardia (n=10), supraventricular or ventricular ectopic beats (n=10), non-sustained ventricular tachycardia (n=2), ventricular tachycardia (n=2), and bradycardia (n=2). In 9 patients (28.1%) the detected arrhythmia was considered an event requiring treatment. Treatment modalities included catheter ablation (n=5), modification of antiarrhythmic drug regime (n=2), adaptation of anticoagulation therapy (n=2), or implantation of a subcutaneous ICD (n=1). Regarding the occurrence of cardiac arrhythmias or a related need for therapeutic intervention, no significant differences were identified with respect to WHO functional class, the presence of pulmonary arterial hypertension or reduced resting peripheral oxygen saturation.

CONCLUSIONS

In symptomatic CHD-patients at risk for life-threatening cardiac events, ILR has a considerable complementary diagnostic value for the detection and differentiation of benign and malignant arrhythmias. Considering the overall low risk of complications, ILR implantation should be considered in patients with CHD of any complexity who need medium or long-term arrhythmia monitoring, especially if short-term Holter monitoring cannot provide sufficient diagnostic certainty.

Evidence for the association between physiological and emotional states in adolescents and young adults without psychopathology under ecologically valid conditions

Well-powered studies on the physiological concomitants underlying affect and its regulation during emerging adulthood are warranted to provide novel insight into mental health. The association between autonomic nervous system activity and emotional states occurring under natural conditions in daily life was investigated in individuals (N = 549, age 14-21, females 45.6%) without any lifetime mental disorder from an epidemiological cohort study in Germany. Using ecological momentary assessment, mood and optimism/pessimism were assessed over 4 days simultaneously with continuous heart rate monitoring. Lower vagal activity was found in mood states accompanied by high arousal (wakefulness, mania) and greater vagal activity in mood states with low arousal (calmness, pessimism). Findings illustrate important associations between autonomic nervous system activity and mood in youth under ecologically valid conditions. Vagal activity presents a prominent pathway by which mood may influence physiological function or vice versa. In contrast to commonly performed laboratory assessments, the ambulatory assessment in participants' daily life allows an application of the results to the field.

'Well-being paradox' revisited: a cross-sectional study of quality of life in over 4000 adults with congenital heart disease

OBJECTIVE

The present cross-sectional study investigated quality of life (QOL) in a large cohort of German adults with congenital heart disease (ACHDs) in association with patient-related and clinical variables.

DESIGN

Cross-sectional survey.

PARTICIPANTS

Between 2016 and 2019, a representative sample of 4014 adults with various forms of congenital heart defect (CHD) was retrospectively analysed. Inclusion criteria were confirmed diagnosis of CHD; participant aged 18 years and older; and necessary physical, cognitive and language capabilities to complete self-report questionnaires.

PRIMARY AND SECONDARY OUTCOME MEASURES

QOL was assessed using the 5-level EQ-5D version (EQ-5D-5L). Sociodemographic and medical information was obtained by a self-devised questionnaire. Associations of QOL with patient-reported clinical and sociodemographic variables were quantified using multiple regression analysis and multiple ordinal logit models.

RESULTS

Overall, ACHDs (41.8±17.2 years, 46.5% female) reported a good QOL comparable to German population norms. The most frequently reported complaints occurred in the dimensions pain/discomfort (mean: 16.3, SD: p<0.001) and anxiety/depression (mean: 14.3, p<0.001). QOL differed significantly within ACHD subgroups, with patients affected by pretricuspid shunt lesions indicating the most significant impairments (p<0.001). Older age, female sex, medication intake and the presence of comorbidities were associated with significant reductions in QOL (p<0.001). CHD severity was positively associated with QOL within the dimensions of self-care (OR 0.148, 95% CI 0.04 to 0.58) and mobility (OR 0.384, 95% CI 0.19 to 0.76).

CONCLUSION

Current findings temper widely held assumptions among clinicians and confirm that ACHDs experience a generally good QOL. However, specific subgroups may require additional support to cope with disease-related challenges. The negative correlation of QOL with age is especially alarming as the population of ACHDs is expected to grow older in the future.

Systematic assessment of health care perception in adults with congenital heart disease in Germany

BACKGROUND

The number of adults with congenital heart disease (ACHD) is steadily rising due to increased survival rate and improved medical resources. Accordingly, more than 330,000 ACHD are currently living in Germany. Almost all of them require lifelong specialized medical follow-up for their chronic heart disease, often accompanied by residua, sequelae, or comorbidities. Primary care physicians (PCPs) are a crucial factor in directing patients to ACHD specialists or specialized institutions, but despite all efforts, the number of ACHD under specialized care is low, the lost-to-follow-up rate is high, and the morbidity and mortality is substantial. The present cross-sectional study was designed to systematically characterize the health care of ACHD from a patient perspective, including (I) use of medical care by ACHD, (II) medical counselling needs, and (III) perceived satisfaction with health care.

METHODS

The German-wide analysis was based on a 25-item questionnaire designed to address different aspects of medical status and health issues of ACHD from their own perspective, performed between May of 2017 and July of 2020.

RESULTS

A total of 4,008 ACHD (52% female; mean age 41.9±17.2 years) completed the questionnaire. The majority of ACHD (3,524, 87.9%) reported, that they consulted their PCP for non-cardiac health problems, and 49.7% (n=1,991) consulted their PCP also for medical problems associated with the underlying CHD. Almost all ACHD reported a need for medical advice concerning exercise capacity and daily life activities, occupational skills, pregnancy, rehabilitation, genetic counselling, insurance, and retirement. A total of 1,840 (45.9%) patients were not aware of the existence of certified ACHD specialists or centers. Moreover, 2,552 (67.6%) of those surveyed were uninformed about patient organizations for ACHD.

CONCLUSIONS

The present study demonstrates that ACHD are largely uninformed about the ACHD care structures available nationwide, although the patients have a great need for specialized follow-up, advice, and care.

Associations of saliva cortisol and hair cortisol with generalized anxiety, social anxiety, and major depressive disorder: An epidemiological cohort study in adolescents and young adults

OBJECTIVES

Most of the observed associations of generalized anxiety disorder (GAD), social anxiety disorder (SAD) and major depressive disorder (MDD) with cortisol concentrations came from clinical and adult study samples, with inconsistent findings, partly due to method variance. We examined cross-sectional and longitudinal associations between GAD, SAD and MDD with saliva and hair cortisol as well as hair cortisol change in a population-based sample of adolescents and young adults, considering relevant co-factors.

DESIGN

Epidemiological cohort study in Dresden, Germany. Data of 1050 individuals (mean age: 17.2 years) assessed at baseline (11/2015-12/2016) and of 605 individuals assessed at 1-year follow-up (FU1) are used.

METHODS

Multivariable regression models were implemented to assess cross-sectional and longitudinal associations of DSM-5 defined 12-month diagnoses of GAD, SAD, and MDD, with short-term (saliva cortisol: cortisol awakening response (CAR) and area under the curve (AUC) as total cortisol) and long-term (hair cortisol) cortisol indices. Multivariable models were adjusted for age or "tanner" stage, waist circumference, tobacco and alcohol consumption, physical inactivity, and hair cortisol dependent confounder. Sex-specific analyses were additionally conducted.

RESULTS

Cross-sectional analyses revealed positive associations between SAD and baseline saliva cortisol in multivariable models (CAR: β-coefficient: 0.12; 95% CI: 0.01; 0.23) but could not be confirmed after adjusting for "tanner" stage or comorbid depression. Cross-sectional analyses concerning GAD and MDD in the full baseline sample yielded no significant associations. Sex-specific linear models revealed a significant inverse cross-sectional association between MDD (β-coefficient: - 2.21; 95% CI: - 3.64; - 0.79) as well as SAD (β-coefficient: - 2.21; 95% CI: - 4.03; - 0.38) with baseline hair cortisol in males, but not in females. In longitudinal analyses, no significant associations were found in the fully adjusted model, except for a positive association between hair cortisol change between baseline and FU1 and FU1-SAD (OR: 1.07; 95% CI: 1.02; 1.12).

CONCLUSIONS

Results confirmed sex-specificity and the role of pubertal development in the association between cortisol with SAD and MDD, while no association emerged regarding cortisol and GAD. Future research in adolescents focusing on the role of cortisol in the pathogenesis of anxiety and depressive disorders would benefit from considering factors like sex-specificity and puberty development as well as comorbidity.

Quality of life in patients with Marfan syndrome: a cross-sectional study of 102 adult patients

Background

Marfan syndrome (MFS) is a genetically determined multiorgan disease that leads to severe physiological and psychological impairments in adult life. Little consensus exists regarding quality of life (QOL) in individuals with MFS. The present study sought to investigate QOL in a representative cohort of adults with MFS.

Methods

Patient-reported outcome measures from a representative sample of 102 adults with MFS (39.3±13.1 years of age; 40.2% female) were retrospectively analyzed and compared with those from adults with different congenital heart defects (CHD), at the German Heart Center Munich. QOL was assessed using the updated five-level version of the EQ-5D.

Results

Differences between both populations were analyzed. Subjects affected by MFS reported an overall reduced QOL. Compared to CHD patients, individuals with MFS scored significantly lower in the dimensions of pain/discomfort, anxiety/depression, mobility and usual activities (P<0.05).

Conclusions

Patients with MFS are at high risk for impaired QOL, especially in mental and physical domains. Psychosocial consequences of MFS cost resources for both, patients and professionals. Current findings highlight the great importance of additional psychological support to cope with disease-related challenges. Increased attention should be directed towards enhancing their subjective wellbeing to potentially improve their QOL and long-term health outcomes.

Provision of medical health care for adults with congenital heart disease associated with aortic involvement

Background

All patients with congenital heart disease (CHD) are chronically ill from their cardiac disease. Despite the increasing evidence that aortic alterations are becoming relevant, the importance of aortopathy in CHD has long been underestimated. This study was conducted to determine the health status of patients and/or the provision of health services of adults with CHD (ACHD) with manifest aortopathy or at risk thereof.

Methods

In a questionnaire-based cross-sectional survey, the "real life"-care of ACHD was analysed, comparing patients with risk of developing aortopathy and/or manifest aortopathy.

Results

Of the 563 enrolled ACHD (49.6% female, mean age 35.8±12.1, 18-86 years) 56.8% (n=320) had a risk of developing aortopathy and/or manifest aortopathy. Of the 320 patients at risk, 187 (33.2% of the total number) had a proven aortopathy. Within this subgroup, the basic medical care for CHD-independent medical problems was given by primary medical care providers [family doctors/general practitioners (GP) in 89.4% (n=286), internists in 13.4% (n=43), physicians of another specialty in 2.5% (n=8)]. Almost all primary medical care providers knew about the CHD of their patients. Even for CHD-specific health problems, the basic medical care of risk patients was provided by a family doctor or GP in 56.6% (n=181) and by an internist in 18.4% (n=59). 30.0% (n=96) primarily consulted another specialist, including cardiologists. Only 32.8% of ACHD at risk had ever been referred to a CHD specialist by a GP for cardiac problems related to their CHD. In contrast, the need for advice was high for ACHD with aortopathy and related mainly to physical activity, employment and education, pregnancy, rehabilitation or health and life insurance. Only 35.5% of patients at risk indicated that their information on specific care structures for ACHD was sufficient, and a further 38.1% of patients were aware of patient organizations.

Conclusions

Even today, aortic involvement in ACHD is an often-overlooked condition, although considerable negative effects on morbidity and mortality exist. As aortopathy gains in importance with increasing age and complexity of CHD, almost all affected ACHD need lifelong medical advice and access to modern, scientifically based care concepts. According to the study-results, primary care providers and also patients are mostly insufficiently informed about the specialized ACHD facilities. The future goal is therefore to create a better awareness of CHD problems among both primary care physicians and the patients concerned.

How current and past anxiety disorders affect daily life in adolescents and young adults from the general population-An epidemiological study with ecological momentary assessment

BACKGROUND

Prior research indicated, based on retrospective assessments of symptomatology, that 25% of individuals with "remitted" anxiety disorders (AD) experience a relapse. The present study used ecological momentary assessment (EMA) to examine how ADs affect everyday life among community adolescents and young adults with current or remitted AD compared to healthy controls and to each other.

METHODS

Data come from the baseline assessment of the epidemiological Behavior and Mind Health study, conducted in Dresden (Germany) from 11/2015-12/2016. The sub-sample analyzed (n = 648, age 14-21) consisted of 65 participants with current DSM-5 AD-diagnosis, 52 participants with lifetime AD-diagnosis but not within the last 6 months (remitted), and 531 healthy controls (no psychopathology; healthy controls [HC]). EMA of various constructs took place 8 times a day for 4 days.

RESULTS

The highest levels of symptoms were reported by those with current AD, followed by remitted AD and HC. Regression analyses revealed significantly worse mood, self-efficacy, quality of life and sleep-quality and more experiential avoidance, stress, negative thoughts and pessimism in remitted and current AD compared to HC. Current AD additional differed significantly from HC in optimism and positive thoughts. Furthermore, individuals with remitted AD without comorbidities differed significantly from HC on five out of 16 constructs.

CONCLUSION

Not only current but also remitted AD is associated with diverse negative experiences in everyday life, which cannot merely be explained by comorbidities. As the remaining burden and impairment in individuals with remitted AD might contribute to relapse, interventions might be targeted to improve mental health.

The interaction of 5-HTT variation, recent stress, and resilience on current anxiety levels in adolescents and young adults from the general population

BACKGROUND

Previous work on gene-environment (GxE) interplay concerning anxiety has focused on the interaction of 5-HTTLPR with childhood adversities or traumatic events whereas the impact of recent stressors is understudied, as is the integration of resilience. The current study aimed to investigate the interactive effect of 5-HTTLPR and recent stress on anxiety in adolescents considering resilience as buffer of a GxE risk constellation.

METHOD

In a random population-based sample of 14-21 years old from Dresden, Germany, (N = 1180; genotyped = 942) recent stress (Daily Hassles [DH] Scale, Perceived Stress Scale, Screening Scale of the Trier Inventory for the Assessment of Chronic Stress), resilience (Connor-Davidson resilience scale) and anxiety (Patient Reported Outcome Measurement Information System Anxiety Short Form) were assessed via questionnaire in 2015 or 2016.

RESULTS

Fractional regression models revealed that resilience interacted with recent stress in form of DH as well as recent chronic stress and 5-HTTLPR regarding anxiety. Participants carrying the more active L_A L_A genotype reported consistently higher levels of anxiety when experiencing more DH or more recent chronic stress and having low levels of resilience. When the resilience scores were high, L_A L_A carriers reported the lowest anxiety scores despite DH or recent chronic stress.

CONCLUSION

Findings revealed an interactive relationship between 5-HTTLPR genotype and recent stress suggesting resilience to function as an additional dimension buffering the impact of a GxE risk constellation. Early interventions to build resilience may be useful to prevent an escalation of distress and associated unfavorable health outcomes.

Non-suicidal self-injury and its co-occurrence with suicidal behavior: An epidemiological-study among adolescents and young adults

OBJECTIVE

Non-suicidal self-injury (NSSI) comprising thoughts and behaviors is common and often co-occurring with suicidal behavior like ideation, plan, and attempt. As limited data are available for adolescents and young adults, this study aims to present prevalence estimates for lifetime NSSI, its co-occurrence with suicidal behavior, conditional probabilities and their association with socio-demographic characteristics, severity characteristics of suicidal behavior, and health service utilization.

METHOD

The epidemiological Behavior and Mind Health (BeMIND) study assessed in 2015/16 a random-community sample of N = 1180 aged 14-21 years from Dresden, Germany, regarding lifetime NSSI via self-administered questionnaire and suicidal behaviors via standardized interview.

RESULTS

Any lifetime NSSI was reported by 19.3% (thoughts: 18.0%, behaviors: 13.6%) of the sample with higher prevalence in females (OR = 2.7, 95% CI 1.9-3.8, P < 0.001). Lifetime prevalence of co-occurring NSSI and suicidal behavior was 7.7%. Females had a 3.3- to 8.8-fold odds of co-occurrence than males. Among those with any NSSI, 39.6% endorsed suicidal behavior, and 66.3% of those with any suicidal behavior reported NSSI. 42.3% of those with any NSSI reported to have used mental healthcare services at any time during their life with higher rates in those with co-occurring suicidal behavior (62.3%).

CONCLUSION

Non-suicidal self-injury and co-occurring suicidal behavior is common in adolescents and young adults-especially females. The limited utilization of mental healthcare services underpins the need for improving recognition of NSSI and suicidal behavior as well as the accessibility of mental healthcare services during adolescence and emerging adulthood.

Correction to: Test-retest reliability of the computer-assisted DIA-X-5 interview for mental disorders

An amendment to this paper has been published and can be accessed via the original article.

Test-retest reliability of the computer-assisted DIA-X-5 interview for mental disorders

BACKGROUND

There is a need of comprehensive standardized diagnostic assessment tools of psychopathology that match recent changes in diagnostic classification systems, such as the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). Therefore, the computer-assisted DIA-X-5 was developed and its test-retest reliability was explored. The DIA-X-5 is based on the DIA-X/M-CIDI (Diagnostisches Expertensystem für psychische Störungen/Munich-Composite International Diagnostic Interview) which referred to the 4th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV).

METHODS

A convenience sample (N = 60, age: 15-67) was interviewed twice with the computer-assisted DIA-X-5 interview, on average nine days apart, by trained and blinded interviewers. The DIA-X-5 is a standardized instrument for research purposes covering symptoms, syndromes and diagnoses from eleven classes of mental disorders according to the DSM-5 with matching F codes of the 10th edition of the International Classification of Diseases (ICD-10).

RESULTS

Kappa values ranged from 0.90 for post-traumatic stress disorder to 0.30 for social anxiety disorder. For age of onset and age of recency, test-retest reliability as measured by intra-class correlation was satisfying with values above 0.90 for most disorders.

CONCLUSIONS

Test-retest reliability of the DIA-X-5 syndromes and diagnoses were comparable to those of previous DSM-IV/DIA-X diagnoses for most disorders. Due to low case numbers for some diagnoses, further research in larger samples is required.

The Behavior and Mind Health (BeMIND) study: Methods, design and baseline sample characteristics of a cohort study among adolescents and young adults

OBJECTIVES

The Behavior and Mind Health (BeMIND) study is a population-based cohort study of adolescents and young adults from Dresden, Germany. The aim is to investigate psychological and behavioral factors linked to a range of mental disorders and health behaviors and their interaction with social-environmental and genetic/biologic factors.

METHODS

A random sample of 14-21 year olds was drawn from the population registry in 2015. The baseline investigation was completed 11/2015-12/2016 (N = 1,180). Assessments include standardized diagnostic interview, cognitive-affective tasks, questionnaires, biosamples, and ecologic momentary assessment in real life with combined actigraphic/geographic monitoring. In the family study component, parents completed similar assessments and provided information on child's early development.

RESULTS

The participation rate (minimum response proportion) was 21.7%; the cooperation rate was 43.4%. Acceptance and completion of study components were high. General health data indicate that more than 80% reported no or only mild impairment due to mental or somatic health problems in the past year; about 20% ever sought treatment for mental health problems or chronic somatic illnesses, respectively.

CONCLUSIONS

Data from BeMIND baseline and follow-up investigations will provide novel insights into contributors to health and disease as adolescents grow into adulthood.

Phenotypic zinc resistance does not correlate with antimicrobial multi-resistance in fecal E. coli isolates of piglets

Background

Following the ban on antimicrobial usage for growth promotion in animal husbandry in the EU, non-antimicrobial agents including heavy metal ions (e.g. zinc and copper), prebiotics or probiotics have been suggested as alternatives. Zinc has extensively been used in pig farming, particularly during weaning of piglets to improve animal health and growth rates. Recent studies, however, have suggested that high dietary zinc feeding during weaning of piglets increases the proportion of multi-drug resistant E. coli in the gut, contraindicating the appropriateness of zinc as an alternative. The underlying mechanisms of zinc effects on resistant bacteria remains unclear, but co-selection processes could be involved. In this study, we determined whether E. coli isolates from intestinal contents of piglets that had been supplemented with high concentrations of zinc acquired a higher tolerance towards zinc, and whether multi-drug resistant isolates tolerated higher zinc concentrations. In addition, we compared phenotypic zinc and copper resistance of E. coli isolates for possible correlation between phenotypic resistance/tolerance to different bivalent ionic metals.

Results

We screened phenotypic zinc/copper tolerance of 210 isolates (including antimicrobial resistant, multi-drug resistant, and non-resistant E. coli) selected from two, independent zinc-feeding animal trials by determining a zinc/copper minimal inhibitory concentration (Merlin, Bornheim-Hersel, Germany). In both trials, groups of piglets were supplemented either with high dietary zinc (> 2000 ppm) or control (50–70 ppm, background) concentrations. Our observations showed that high concentration zinc exposure did not have an effect on either zinc or copper phenotypic tolerance of E. coli isolates from the animals. No significant association was found between antimicrobial resistance and phenotypic zinc/copper tolerance of the same isolates.

Conclusion

Our findings argue against a co-selection mechanism of antimicrobial drug-resistance and zinc tolerance after dietary zinc supplementation in weaning piglets. An explanation for an increase in multi-drug resistant isolates from piglets with high zinc dietary feeding could be that resistant bacteria to antimicrobial agents are more persistent to stresses such as zinc or copper exposure.

[Medical care of adults with congenital heart diseases : Present and future]

Congenital heart diseases (CHD) are the most common types of congenital organ defects. Thanks to medical progress in congenital cardiology and heart surgery, most children with CHD reach adulthood. Despite primarily successful treatment residual and subsequent conditions as well as (non)cardiac comorbidities can influence the chronic course of the disease and lead to a higher morbidity and mortality. Adults with congenital heart disease (ACHD) in Germany are not tied to the healthcare structure despite the great need for aftercare. According to the results of the medical care of ACHD (MC-ACHD) study, ACHD centers and specialists in Germany are insufficiently perceived despite increased complication rates and the great need for specialist guidance. General practitioners and patients are not adequately informed about existing ACHD facilities. A better awareness of the ACHD problem should be created at the level of primary medical supply in order to optimize care and to reduce morbidity and mortality. Improved future-oriented patient care includes lifelong regular follow-up and the possibility of interdisciplinary, integrated medical care of CHD.

Prevalence, Onset, and Course of Suicidal Behavior Among Adolescents and Young Adults in Germany

Importance

Suicidal behavior is a leading cause of death among adolescents and young adults. In light of the ideation-to-action framework, the delineation of frequency and temporal characteristics of such behavior during this developmental period is crucial.

Objectives

To provide lifetime and 12-month prevalence estimates of suicidal behavior, including ideation, plan, and attempt, in adolescents and young adults of the general population, and to provide information about age at onset, temporal characteristics of suicidal behavior, including duration (number of years between onset and last occurrence) and frequency (number of episodes), and transition patterns across suicidal behaviors.

Design, Setting, and Participants

A cross-sectional epidemiological study was conducted in a random community sample of 1180 adolescents and young adults aged 14 to 21 years assessed in 2015 to 2016 in Dresden, Germany. Data analysis was performed from October 2018 to March 2019.

Main Outcomes and Measures

Lifetime and 12-month suicidal behavior (ideation, plan, and attempt) were assessed with a standardized diagnostic interview (Munich-Composite International Diagnostic Interview) by trained clinical interviewers. The onset, frequency, and duration of suicidal behavior were assessed by questionnaire.

Results

Of the 1180 participants (495 male [weighted percentage, 51.7%]; mean [SD] age, 17.9 [2.3] years), 130 participants (10.7%; 95% CI, 9.0%-12.8%), 65 participants (5.0%; 95% CI, 3.9%-6.5%), and 41 participants (3.4%; 95% CI, 2.4%-4.7%) reported lifetime suicidal ideation, plan, and attempt, respectively. Any lifetime suicidal behavior was reported by 138 participants (11.5%; 95% CI, 9.7%-13.7%). Age-specific cumulative incidence estimates indicated an increase in suicidal behavior during adolescence, starting at age 10 years (<1%), increasing slightly until the age of 12 years (2.2%), and then increasing sharply thereafter until age 20 years (13.5%). There were different patterns among female and male participants for ideation, plan, and attempt, with an overall higher incidence among female participants for ideation (hazard ratio, 1.51; 95% CI, 1.02-2.22; P = .04), for plan (hazard ratio, 3.31; 95% CI, 1.72-6.36; P < .001), and, among those older than 14 years, for attempt (hazard ratio, 3.07; 95% CI, 1.11-8.49; P = .03). Of those with suicidal ideation, 66.0% reported persistent or recurrent ideation over more than 1 year with 75.0% reporting more than 1 episode. Of the participants with lifetime suicidal ideation, 47.0% reported a suicide plan and 23.9% reported a suicide attempt. The transition to suicide plan or attempt occurred mainly in the year of onset of suicidal ideation or plan; of those who transitioned, 74.9% transitioned from ideation to plan, 71.2% transitioned from ideation to attempt, and 85.4% transitioned from plan to attempt in the same year.

Conclusions and Relevance

There is an urgent public health need for timely identification of suicidal behavior in adolescents and young adults to terminate persistent or recurrent suicidal tendencies and to interrupt the ideation-to-action transition.

Current research status on the psychological situation of parents of children with congenital heart disease

Congenital heart diseases (CHD) are a leading cause of morbidity in children with a high impact on the psychological health of parents. Possible short-term and long-term psychological problems among parents are addressed in the current paper. The diagnosis of CHD paired with subsequent surgical and interventional treatment and prolonged hospital stays cause acute psychological distress and can lead to posttraumatic stress disorders (PTSD). As the disease course progresses, the impact on parents' health tends to decrease, but the risk of developing long-term psychological issues remains high. Studies have focused mainly on stress and other distressing symptoms without explicitly addressing the effects of a CHD diagnosis on the family system. Since the social environment may play an important role in parent's life, it may be useful to conduct studies to address these issues. In particular, the psychological situation of the father and the impact of the child's disease on the different dimensions of the father's life, such as parenting skills and influences on the parental relationship, have been largely neglected. Recent research has also disregarded the impact of CHD on siblings of the affected child. Research on chronic diseases in general has shown that the children's age and severity of the disease are related to an increased level of stress. Given the severity of CHD, anxiety and depression were higher in parents with children with more severe conditions. In addition, the results suggest that a positive construction of the parent-child relationship (attachment and bonding) is impaired, especially in mothers. Mothers reported worries and concerns about the challenging tasks they would face after learning about their child's CHD and how they can deal with their child's needs. It has also been shown that the child's illness has a negative impact on the whole family system, including the parent's relationship. Impairments on the parental relationship were perceived differently among mothers and fathers. Thus, there is high need for major changes to be identified, developed and implemented in the psychological care of parents with chronically ill children. So far, research has focused more on the psychological status of parents with chronically ill children, but less research has closely examined the effects of a child's CHD on its parent's mental health even though there is a high demand in additional support. A holistic treatment approach should include professional parental support, especially during children's hospitalization, information on the home care resources and services (especially respite services) and psychological support for parents.

Overweight and obesity: an emerging problem in patients with congenital heart disease

Due to technological and medical advances the population of adults with congenital heart disease (ACHD) is constantly growing. Worldwide, congenital heart disease (CHD) affects 1.35-1.5 million children each year and the number of ACHD meanwhile exceeds the number of CHD children. It has been found that a substantial number of ACHD present problematic health behaviors, such as physical inactivity and bad nutritional habits. Recent studies document alarming rates of overweight and obesity among CHD patients which may consequently lead to further health complications in this population. The present article focuses on the distinct psychosocial effects resulting from the diagnosis of CHD and their impact on developing disordered eating patterns and excess weight. It seeks to identify unique risk factors and relevant explanations associated with the increasing prevalence of obesity among CHD patients. This review suggests a vital need to establish clinical guidelines for nutrition and weight management in this patient population as part of a holistic treatment approach.

The value of hand grip strength (HGS) as a diagnostic and prognostic biomarker in congenital heart disease

Background

In patients with congenital heart disease (CHD), there is little data on the diagnostic and prognostic relevance of hand grip strength (HGS) for clinical assignment, while in the general population the loss of muscle strength and mass is an important risk factor in cardiovascular disease which is conversely associated with morbidity and all-cause mortality. This study aimed to assess the degree of muscle dysfunction using HGS as a biomarker in a large group of patients with CHD who often develop muscle dysfunction.

Methods

In total, 385 patients (27.6±13.1 years, 43% female) were included and assigned to 5 diagnostic groups: complex anomalies (n=131), left heart anomalies/aortopathies (n=107), right heart/pulmonary artery anomalies (n=92), primary left to-right-shunts (n=42) and miscellaneous CHD (n=13). Patients with Fontan circulation, chronic cyanosis, morphologic right systemic ventricle, arterial switch operation, or Ebstein's anomaly were analyzed separately. A control group (CG) consisted of 124 healthy individuals (30.1±12.1 years, 42% female). HGS was measured with a Jamar Hydraulic Hand Dynamometer.

Results

HGS was reduced in CHD patients compared to controls (35.2±14.6 versus 43.7±14.4 kg). Most impairments were present in females (26.1±7.6 kg). Patients with cyanosis had lower HGS values compared to acyanotic CHD patients (P=0.03). Patients with left heart lesions had the highest HSG values (40.7±14.7 kg), while patients with primary left-to-right shunt lesions had the lowest HSG values (30.9±11.3 kg). Within specific groups of cardiac anomalies, patients with Fontan circulation showed the lowest (P=0.033) and patients with a morphologic right system ventricle showed higher results (P=0.004). The late mid-term survival was favorable, and 7 patients (1.8%) died in a median interval of 422 days (range, 206-1,824 days) after HGS-testing.

Conclusions

This study provides the most comprehensive data on the use of HGS in CHD to date. Grip strength is an easily applicable, repeatedly usable and a cost-effective diagnostic tool to gain a quick, quantifiable assessment of the patient's current muscle function as an expression of cardiac fitness. Considering the low number of patients who died in the observation period, HGS may not be a suitable tool for survival assessment or identification of patients at risk. However, HGS is well suited to determine muscle function and strength and thereby to identify and to follow-up patients who have an increased cardiovascular risk.

Cardiovascular risk algorithms in primary care: Results from the DETECT study

Guidelines for prevention of cardiovascular diseases use risk scores to guide the intensity of treatment. A comparison of these scores in a German population has not been performed. We have evaluated the correlation, discrimination and calibration of ten commonly used risk equations in primary care in 4044 participants of the DETECT (Diabetes and Cardiovascular Risk Evaluation: Targets and Essential Data for Commitment of Treatment) study. The risk equations correlate well with each other. All risk equations have a similar discriminatory power. Absolute risks differ widely, in part due to the components of clinical endpoints predicted: The risk equations produced median risks between 8.4% and 2.0%. With three out of 10 risk scores calculated and observed risks well coincided. At a risk threshold of 10 percent in 10 years, the ACC/AHA atherosclerotic cardiovascular disease (ASCVD) equation has a sensitivity to identify future CVD events of approximately 80%, with the highest specificity (69%) and positive predictive value (17%) among all the equations. Due to the most precise calibration over a wide range of risks, the large age range covered and the combined endpoint including non-fatal and fatal events, the ASCVD equation provides valid risk prediction for primary prevention in Germany.

Current research status on the psychological situation of adults with congenital heart disease

Due to technological and medical advances the population of adults with congenital heart disease (ACHD) is growing. Worldwide, congenital heart disease (CHD) affects 1.35-1.5 million children each year and more than 90% reach adulthood. Given the heterogeneity of CHD, survivors are faced with not only complex medical but also psychological challenges which may manifest in mental health problems, such as depression, anxiety and posttraumatic stress disorder. This review focuses on the emotional dimension of CHD. More precisely, it summarizes the present state of research on the prevalence of emotional distress in ACHD. Theoretical models provide a framework for possible explanations of mental health issues in ACHD. Additionally, the review examines the relation between psychological processes and overall health considering the latest scientific findings on coping with chronic illness (illness identity). There is still insufficient knowledge on the psychosocial treatment of mental health issues in the growing population of ACHD. This review suggests a vital need to further investigate the psychological situation of ACHD on a large-scale basis in order to establish a holistic treatment approach to accommodate the patients' special needs.

Improving medical care and prevention in adults with congenital heart disease-reflections on a global problem-part II: infective endocarditis, pulmonary hypertension, pulmonary arterial hypertension and aortopathy

Despite relevant residua and sequels, follow-up care of adults with congenital heart disease (ACHD) is too often not performed by/in specialized and/or certified physicians or centers although major problems in the long-term course may develop. The most relevant encompass heart failure, cardiac arrhythmias, heart valve disorders, pulmonary vascular disease, infective endocarditis (IE), aortopathy and non-cardiac comorbidities. The present publication emphasizes current data on IE, pulmonary and pulmonary arterial hypertension and aortopathy in ACHD and underlines the deep need of an experienced follow-up care by specialized and/or certified physicians or centers, as treatment regimens from acquired heart disease can not be necessarily transmitted to CHD. Moreover, the need of primary and secondary medical prevention becomes increasingly important in order to reduce the burden of disease as well as the socioeconomic burden and costs in this particular patient group.

Improving medical care and prevention in adults with congenital heart disease-reflections on a global problem-part I: development of congenital cardiology, epidemiology, clinical aspects, heart failure, cardiac arrhythmia

Today most patients with congenital heart defects (CHD) survive into adulthood. Unfortunately, despite relevant residua and sequels, follow-up care of adults with congenital heart disease (ACHD) is not performed in specialized and/or certified physicians or centres. Major problems in the long-term course encompass heart failure, cardiac arrhythmias, heart valve disorders, pulmonary vascular disease, infective endocarditis, aortopathy and non-cardiac comorbidities. Many of them manifest themselves differently from acquired heart disease and therapy regimens from general cardiology cannot be transferred directly to CHD. It should be noted that even simple, postoperative heart defects that were until recently considered to be harmless can lead to problems with age, a fact that had not been expected so far. The treatment of ACHD has many special features and requires special expertise. Thereby, it is important that treatment regimens from acquired heart disease are not necessarily transmitted to CHD. While primary care physicians have the important and responsible task to set the course for adequate diagnosis and treatment early and to refer patients to appropriate care in specialized ACHD-facilities, they should actively encourage ACHD to pursue follow-up care in specialized facilities who can provide responsible and advanced advice. This medical update emphasizes the current data on epidemiology, heart failure and cardiac arrhythmia in ACHD.

Testosterone is not associated with traits of optimism or pessimism: Observational evidence from the prospective DETECT study

Background

Previous experimental research on testosterone (T) and psychological traits is inconclusive. Thus, we performed the first large-scale observational study of the association between T and dispositional optimism / pessimism.

Methods

We used prospective data from 6,493 primary-care patients (3,840 women) of the DETECT study (Diabetes Cardiovascular Risk-Evaluation: Targets and Essential Data for Commitment of Treatment), including repeated immunoassay-based measurement of serum T and optimism / pessimism assessed by the revised Life-Orientation Test (LOT-R). Cross-sectional and longitudinal associations of baseline T and one-year change in T with optimism and pessimism were investigated using age- and multivariable-adjusted regression models.

Results

Cross-sectional analyses showed no association of T with optimism or pessimism in both sexes. Longitudinal analyses also showed no association of baseline T with optimism or pessimism at four-year follow-up. Multivariable analyses of total LOT-R score yielded similarly non-significant results (β-coefficient per unit change in T for men: -0.01 (95% CI: -0.24–0.22), women: 0.08 (-0.03–0.20)). Furthermore, change in T was not related to optimism or pessimism at four-year follow-up.

Conclusions

The present observational study of a large-scale prospective sample showed no association of T with optimism or pessimism. Integrating further experimental and interventional evidence from alternative methodological approaches would strengthen this conclusion and establish stronger evidence about the potential hormonal basis of psychological traits.

Association of postpartum hypocalcemia with early-lactation milk yield, reproductive performance, and culling in dairy cows

Periparturient hypocalcemia is frequently observed and considered as a gateway disease that is associated with various health issues. The objective of this study was to evaluate the association of hypocalcemia with early-lactation milk yield, reproductive performance, and culling across a large number of different managerial systems. A prospective cohort study was conducted based on a convenience sample of 125 dairy herds from 8 federal states of Germany between February 2015 and August 2016. A blood sample was drawn from 1,709 animals within 48 h after parturition and analyzed for serum calcium concentration. After discarding cows (n = 283) with missing data, a total of 1,426 cows were considered for final analyses. The median time from calving to sampling was 14.0 h (interquartile range = 5.0-24.9 h). For each herd, a record of the herd management software was requested 150 d after the last cow was sampled. Serum calcium concentration of each cow was associated with early-lactation milk yield (Dairy Herd Improvement Association equivalent test 1 to 3), reproductive performance [days in milk (DIM) at first artificial insemination (AI), pregnancy at first AI, time to pregnancy within 150 DIM], and culling (until 60 DIM) data. Generalized linear mixed models were used to analyze continuous or categorical data. Shared frailty models were used for time to event data. Five different thresholds were used to define hypocalcemia. Thresholds ranged from 1.8 to 2.2 mmol/L using 0.1-mmol/L increments. Clinical hypocalcemia was defined as serum calcium concentration <2.0 mmol/L in combination with clinical signs (e.g., recumbency). The effect of hypocalcemia on milk yield was conditional on parity. In primiparous cows a serum calcium concentration <2.0 mmol/L (6.4% of cows were below this threshold) had no effect on milk production, whereas there was a tendency for multiparous cows with a serum calcium concentration <2.1 mmol/L (63.2% of cows were below this threshold) to produce 0.80 kg/d more milk compared with multiparous cows at or above the threshold. Multiparous cows suffering from clinical hypocalcemia produced 2.19 kg/d less milk compared with normocalcemic cows in early lactation. Calcium status was not associated with days to first insemination. Cows with a serum calcium concentration <1.9 mmol/L (34.6% of cows below this threshold) had decreased odds (odds ratio = 0.56) of pregnancy at first AI. A serum calcium concentration <1.8 mmol/L (24.1% of cows below this threshold) had a significant effect on time to pregnancy. Compared with animals with a serum calcium concentration ≥1.8 mmol/L, the hazard of becoming pregnant within 150 DIM was reduced when cows had a serum calcium concentration <1.8 mmol/L (hazard ratio = 0.68). Cows with a serum calcium concentration <2.0 mmol/L (44.3% of cows were below this threshold) had a 1.69 times greater hazard of being culled within the first 60 DIM compared with normocalcemic animals. The present study shows that the association of hypocalcemia with milk yield was conditional on parity and serum calcium concentration measured once within 48 h after calving. Considering reproductive performance and culling in early lactation, a negative effect of postpartum hypocalcemia was demonstrated.

The Dresden Burnout Study: Protocol of a prospective cohort study for the bio-psychological investigation of burnout

OBJECTIVES

The Dresden Burnout Study (DBS) is a 12-year longitudinal cohort study that aims to provide a description of the burnout syndrome on the basis of time and symptom criteria with a special focus on the search for biomarkers. Biological and psychosocial approaches are applied to examine the long-term course and consequences of burnout within a population-based German-speaking sample aged 18 to 68 years.

METHODS

Demographics and psychosocial data are generated by online assessments, including demographics and questionnaires on burnout, burnout-related constructs, work-environment, and health-related factors. The lab-based biomarker assessment includes endocrine, physiological, immunological, and epigenetic markers obtained from blood and hair samples. In addition, heart rate variability is also measured repeatedly. Within the first 2 years, the DBS collected psychosocial data from over 7,600 participants with biological data obtained from more than 800 individuals. During the following 10 years, detailed assessments of biomarkers and psychosocial factors will be collected in annual study waves.

RESULTS

Results will be generated during the following decade.

CONCLUSION

The findings of the DBS are expected to pave the road for an in-depth biopsychosocial characterization of burnout and to give insight into the long-term course and potential mental and physical health consequences of the burnout syndrome.
