Development of heart failure in long-term survivors of childhood cancer: results from the cvss study

Background

Long-term survivors of childhood cancer (CCS) are at increased risk for cardiovascular sequelae, including heart failure (HF) as the largest non-malignant contributor to excess death. Yet, little is known about the risk factors, mechanisms of cardiac dysfunction and prevalence of different stages of HF in these patients.

Purpose

To investigate the development and prevalence of HF phenotypes in CCS compared to the general population.

Methods

The CVSS study is a prospective single-center cohort study investigating cardiovascular sequelae of CCS. Patients were eligible for the study when they were diagnosed with a neoplasia according to the International Classification of Childhood Cancer (ICCC 3) at an age prior to 15 years between 1980 and 1990, survived more than five years after initial cancer diagnosis and received antineoplastic treatment. Between 2013 and 2016, study individuals underwent a comprehensive, standardized clinical investigation in the CVSS cohort study including echocardiographic examination. HF was categorized as stages A to D according to current HF guidelines of the American Heart Association (AHA). A population-based sample free of cancer (age- and sex matched) serves as control group.

Results

From 1,002 individuals, all CCS with history of chemo- or radiotherapy and no subsequent neoplasia (n=877) were included (mean age 34.2 (±5.5) years, 44.7% (N=392) female). Age at diagnosis was 6.28 years (±4.24) and the mean interval from the date of diagnosis of cancer to the date of completion of baseline examination 28.5±3.2 years. Based on echocardiographic examination, clinical data and biomarker assessment, 26.6% of CCS were diagnosed with HF stage A, 21.1% with HF stage B and 2.1% with symptomatic HF, i.e. HF stage C/D. Importantly, prevalence of different HF stages varied strongly by specific tumor history. Compared to the population, the prevalence ratio (PR) was 1.16 [95% confidence interval 1.02/1.31] for stage A HF and 1.91 [1.63/2.23] for the composite of stage B to D HF in an age- and sex-adjusted Poisson regression model. Multivariable linear regression with the systolic marker left ventricular ejection fraction as dependent variable and adjustment for tumor entities, age, sex, and cardiovascular risk factors (CVRF) revealed a lower EF in patients with history of bone tumors (β −6.0 [−8.1/−3.0]), soft tissue sarcoma (β −2.2 [−4.1/−0.35]), leukemia (β −0.84 [−1.8/0.08]) and renal tumors (β −1.8 [−4.0/0.27]) compared to the population. In contrast, the same model for the diastolic marker E/E', showed an association only with CVRF, but not with tumor entities.

Conclusion

The prevalence of stage B to D HF was significantly higher among long-term CCS in the 3rd to 5th age decade compared to the population and varied strongly by tumor entity. Systolic dysfunction was primarily associated with history of tumor entities, whereas diastolic dysfunction was associated with the higher burden of CVRF in CCS.

Disturbed glucose metabolism and left ventricular geometry in the general population – results from the Gutenberg health study

Background

Prediabetes and type 2 diabetes mellitus (T2DM) have been demonstrated to alter left ventricular geometry and promote left ventricular (LV) hypertrophy (LVH). However, the impact of impaired glucose metabolism on cardiac structure is still not completely understood and controversially discussed.

Purpose

To investigate the impact of prediabetes and T2DM on left ventricular geometry and their potential interaction with LVH in the prediction of survival.

Methods

Data from the Gutenberg Health Study (N=15,010) – a population-based study with highly standardized phenotyping – were analysed. Information was obtained from computer-assisted personal interviews, medical-technical examinations, laboratory measurements in fasting state and echocardiography according to standard operating procedures with detailed quality control. Individuals with other types of diabetes or hyperinsulinemia were excluded from analysis. Study participants aged 35 to 74 years were categorized according to long-term glucose state (HbA1c) into euglycemia, prediabetes and T2DM. LV geometry was assessed according to current guideline recommendations. Multivariable regression analyses were performed to evaluate the association between glucose state and measures of left ventricular geometry. Survival analyses were carried out to assess the prognostic impact dependent on the presence of LVH.

Results

The analysis sample comprised 14,852 individuals aged 55.0±11.1 years (49.5% females). The prevalence of LVH was 10.2% (n=1,227) in euglycaemia, 17.2% in prediabetes and 23.8% in T2DM. Similarly, concentric and eccentric hypertrophy had the highest prevalence in T2DM (13.1% and 10.8%, respectively), followed by prediabetes (9.6% and 8.2%) and euglycaemia (5.7% and 4.5%). In multivariable regression analysis with adjustment for age, sex, traditional cardiovascular risk factors (CVRF), C-reactive protein and LV function, T2DM had a higher impact on relative wall thickness (β: 0.0135 [0.0087; 0.0182]; P<0.0001) and LV mass (β: 5.46 [4.89; 6.03]; P<0.0001) than prediabetes (β-estimaterelative wall thickness 0.00145 [−0.0031; 0.006]; P=0.53; β-estimateLV mass 2.73 [2.19; 3.28]; P<0.0001) compared to euglycemia. During a median follow-up of 9.0 [interquartile range 7.7; 10.4] years, prediabetes did not predict all-cause mortality independent of age, sex and CVRF in Cox regression analysis in individuals without LVH (hazard ratio (HR) 1.15 [0.90; 1.46]; P=0.27) or those with LVH (HR 1.46 [0.97; 2.18]; P=0.069). In comparison, T2DM was a strong and independent predictor of mortality both in absence (HR 1.59 [1.29; 1.96]; P<0.0001) and presence of LVH (HR 2.67 [1.94; 3.66]; P<0.0001).

Conclusions

Although cardiac geometry is altered both in presence of prediabetes and T2DM, only T2DM is a strong predictor of premature mortality in the general population. This merits consideration for future preventive strategies to decrease the burden of cardiovascular disease.

Comorbidity, family history and personality traits in pathological gamblers compared with healthy controls

Background

While DSM-5 classified pathological gambling as an addictive disorder, there is debate as to whether ICD-11 should follow suit. The debate hinges on scientific evidence such as neurobiological findings, family history of psychiatric disorders, psychiatric comorbidity, and personality variables.

Methods

In the “Baden-Württemberg Study of Pathological Gambling”, we compared a group of 515 male pathological gamblers receiving treatment with 269 matched healthy controls. We studied differences in sociodemographic characteristics, gambling-related variables, psychiatric comorbidity (lifetime), family history of psychiatric conditions, as well as personality traits such as impulsivity (Barratt Impulsiveness Scale), sensation seeking (Zuckerman's Sensation Seeking Scale) and the NEO-FFI big five. Personality traits were validated in an age- and ethnicity-matched subsample of “pure” gamblers without any psychiatric comorbidity (including nicotine dependence). Data were analyzed using two-sample t-tests, Chi2 analyses, Fisher's exact test and Pearson correlation analysis, as appropriate. Bonferroni correction was applied to correct for multiple comparisons.

Results

Only 1% of the gamblers had been diagnosed with an impulse control disorder other than gambling (ICD-10). Notably, 88% of the gamblers in our sample had a comorbid diagnosis of substance dependence. The highest axis I comorbidity rate was for nicotine dependence (80%), followed by alcohol dependence (28%). Early age of first gambling experience was correlated with gambling severity. Compared to first-degree relatives of controls, first-degree relatives of pathological gamblers were more likely to suffer from alcohol dependence (27.0% vs. 7.4%), pathological gambling (8.3% vs. 0.7%) and suicide attempts (2.7% vs. 0.4%). Significant group differences were observed for the NEO-FFI factors neuroticism, agreeableness and conscientiousness. Gamblers were also more impulsive than controls, but did not differ from controls in terms of sensation seeking.

Conclusions

Our findings support classifying pathological gambling as a behavioural addiction in the ICD-11. This decision will have a significant impact on the approaches available for prevention (e.g. age limits) and treatment.

Genome-wide association study of pathological gambling

Background

Pathological gambling is a behavioural addiction with negative economic, social, and psychological consequences. Identification of contributing genes and pathways may improve understanding of aetiology and facilitate therapy and prevention. Here, we report the first genome-wide association study of pathological gambling. Our aims were to identify pathways involved in pathological gambling, and examine whether there is a genetic overlap between pathological gambling and alcohol dependence.

Methods

Four hundred and forty-five individuals with a diagnosis of pathological gambling according to the Diagnostic and Statistical Manual of Mental Disorders were recruited in Germany, and 986 controls were drawn from a German general population sample. A genome-wide association study of pathological gambling comprising single marker, gene-based, and pathway analyses, was performed. Polygenic risk scores were generated using data from a German genome-wide association study of alcohol dependence.

Results

No genome-wide significant association with pathological gambling was found for single markers or genes. Pathways for Huntington's disease (P-value = 6.63 × 10−3); 5′-adenosine monophosphate-activated protein kinase signalling (P-value = 9.57 × 10−3); and apoptosis (P-value = 1.75 × 10−2) were significant. Polygenic risk score analysis of the alcohol dependence dataset yielded a one-sided nominal significant P-value in subjects with pathological gambling, irrespective of comorbid alcohol dependence status.

Conclusions

The present results accord with previous quantitative formal genetic studies which showed genetic overlap between non-substance- and substance-related addictions. Furthermore, pathway analysis suggests shared pathology between Huntington's disease and pathological gambling. This finding is consistent with previous imaging studies.

Coagulation and inflammation in long-term cancer survivors: results from the adult population

Essentials The increase of cancer survival remains curtailed by cardiovascular mortality. We studied a large range of inflammatory and coagulation biomarkers in long-term cancer survivors. Cancer history has an important impact on mortality independent of cardiovascular risk factors. Fibrinogen and von Willebrand factor are potential biomarkers in survivors of increased mortality.

SUMMARY

Background The advances in cancer treatment and detection of early cancer have resulted in a steady increase in the number of of cancer survivors over the years. However, because of the long-term toxic effects of chemotherapy and radiotherapy, the incidence of cardiovascular disease (CVD) is increasing in survivors. Objectives To investigate traditional cardiovascular risk factors (CVRFs), inflammation and the coagulation profile in long-term cancer survivors (cancer diagnosis ≥ 5 years) from a large adult population-based study sample. Methods The presence of cardiovascular risk factors (CVRFs) and laboratory markers were compared in individuals with (n = 723) and without (n = 13626) a long-term history of cancer from the Gutenberg Health Study. Data on coagulation factors, D-dimer and von Willebrand factor (VWF) activity were available for 4974 individuals (n = 244 cancer survivors). Results In multivariable regression models, a history of cancer was, independently of CVRFs and CVD, associated with higher fibrinogen levels (β 6.99, 95% confidence interval [CI] 1.16-12.8), VWF activity (β 5.08, 95% CI 0.02-10.1), and antithrombin activity (β 1.85, 95% CI 0.44-3.27). Cancer survivors with CVD showed notably higher VWF activity than individuals with CVD without a history of cancer, with a difference in the means of 23.0 (7.9-38.1). Multivariate Cox regression analysis, adjusted for CVRFs, confirmed that a long-term history of cancer is associated with a 72% higher mortality. Increased mortality in cancer survivors was dependent on fibrinogen level and VWF activity level. Conclusion Cancer survivors showed a worse inflammation and coagulation profile than individuals without a history of cancer. Overall mortality in long-term cancer survivors was increased independently of traditional CVRFs. These results underline the need to further investigate plasma biomarkers as complementary cardiovascular risk predictors in cancer survivors.

Subclinical levels of anxiety but not depression are associated with planning performance in a large population-based sample

BACKGROUND

Major depression and anxiety disorders are known to negatively influence cognitive performance. Moreover, there is evidence for greater cognitive decline in older adults with generalized anxiety disorder. Except for clinical studies, complex executive planning functions and subclinical levels of anxiety have not been examined in a population-based sample with a broad age range.

METHODS

Planning performance was assessed using the Tower of London task in a population-based sample of 4240 participants aged 40-80 years from the Gutenberg Health Study (GHS) and related to self-reported anxiety and depression by means of multiple linear regression analysis.

RESULTS

Higher anxiety ratings were associated with lower planning performance (β = -0.20; p < 0.0001) independent of age (β = 0.03; p = 0.47). When directly comparing the predictive value of depression and anxiety on cognition, only anxiety attained significance (β = -0.19; p = 0.0047), whereas depression did not (β = -0.01; p = 0.71).

CONCLUSIONS

Subclinical levels of anxiety but not of depression showed negative associations with cognitive functioning independent of age. Our results demonstrate that associations observed in clinical groups might differ from those in population-based samples, also with regard to the trajectory across the life span. Further studies are needed to uncover causal interrelations of anxiety and cognition, which have been proposed in the literature, in order to develop interventions aimed at reducing this negative affective state and to improve executive functioning.

Current and cumulative night shift work and subclinical atherosclerosis: results of the Gutenberg Health Study

PURPOSE

The study examines the association between exposure to current and cumulative night shift work and subclinical parameters of atherosclerosis.

METHODS

Participants of a population-based cohort study (the Gutenberg Health Study, N = 15,010) aged 35-64 years were examined at baseline (2007-2012). Investigations included measurements of arterial stiffness, vascular function [reactive hyperaemia (RH) index], and intima media thickness (IMT). Also, a complete job history (including up to 15 periods), occupational exposures, a variety of lifestyle, and dispositional variables were enquired.

RESULTS

Night shift work was performed by 1071 out of 8065 currently employed individuals. The strongest association after adjustment for age, sex, job complexity level, being a manager, overtime work, and noise appeared for more than 660 night shifts within the last 10 years and a significantly increased arterial stiffness of 0.33 m/s. This reflects a 4 % flow velocity increase for individuals with more than 660 night shifts compared to non-night workers. Regarding the entire professional life, night shift workers showed a significantly decreased vascular function by -0.054 RH index points by using the same adjustment. IMT values did not differ statistically from non-night workers. Lifestyle and dispositional factors showed an influence on all used subclinical atherosclerosis parameters.

CONCLUSIONS

The cross-sectional results demonstrate an association between night work and detrimental changes in the atherosclerotic process. The association is more pronounced with more years in night shift and is partly explained by lifestyle and dispositional factors. Longitudinal analyses are necessary to confirm the results.

Adult attachment representation moderates psychotherapy treatment efficacy in clinically depressed inpatients

BACKGROUND

We explored in a sample of clinically depressed patients the influence of attachment security and unresolved trauma on psychotherapeutic outcome as well as changes in attachment representation through psychotherapeutic intervention.

METHODS

The sample consisted of 85 women (aged 19-52), 43 clinically depressed patients from a psychosomatic inpatient unit, and 42 healthy control subjects matched for age and education. Average length of hospitalization in the patient group was eight weeks. Attachment representations were assessed with the Adult Attachment Interview at the time of admission (baseline) and at discharge. Depressive symptoms were measured using the PHQ-9 at T1 and T2.

RESULTS

Insecure attachment representations were overrepresented in depressed patients. Treatment effects were moderated by baseline attachment representation: patients with higher attachment security scores at admission benefited more from the inpatient treatment and were less depressed at time of discharge than less secure patients (η(2)=.07). Generally, attachment security increased (η(2)=.19) and depressive symptoms decreased (η(2)=.23) after inpatient psychotherapy treatment in the patient group. No significant effects for unresolved symptoms were found.

LIMITATIONS

The study is not a randomized controlled study, but used a quasi-experimental matched control group design with female subjects only.

CONCLUSIONS

Our results suggest that attachment representations play a major role in both the development and treatment of clinical depression. Baseline attachment security may influence psychotherapeutic outcome, perhaps through relational factors such as therapeutic working alliance. Inpatient psychotherapy may also need to address psychological issues associated with depression such as attachment insecurity.

Methylation of the oxytocin receptor gene in clinically depressed patients compared to controls: The role of OXTR rs53576 genotype

The emerging field of epigenetics provides a biological basis for gene-environment interactions relevant to depression. We focus on DNA methylation of exon 1 and 2 of the oxytocin receptor gene (OXTR) promoter. The research aims of the current study were to compare OXTR DNA methylation of depressed patients with healthy control subjects and to investigate possible influences of the OXTR rs53576 genotype. The sample of the present study consisted of 43 clinically depressed women recruited from a psychosomatic inpatient unit and 42 healthy, female control subjects - mean age 30 years (SD = 9). DNA methylation profiles of the OXTR gene were assessed from leukocyte DNA by means of bisulfite sequencing. Depressed female patients had decreased OXTR exon 1 DNA methylation compared to non-depressed women. The association between depression and methylation level was moderated by OXTR rs53576 genotype. Exon 2 methylation was associated with OXTR rs53576 genotype but not with depression. Our findings suggest exon-specific methylation mechanisms. Exon 1 methylation appears to be associated with depressive phenotypes whereas exon 2 methylation is influenced by genotype. Previously reported divergent associations between OXTR genotype and depression might be explained by varying exon 1 methylation. In order to further understand the etiology of depression, research on the interplay between genotype, environmental influences and exon-specific methylation patterns is needed.

Combining cross-sectional data on prevalence with risk estimates from a prediction model. A novel method for estimating the attributable risk

OBJECTIVES

Estimation of the attributable risk for fatal diseases by combining two different data sources.

METHODS

We derive a method to estimate the attributable risks of different risk factors by combining general mortality risks with up-to-date prevalences of the risk factors using estimates from a risk prediction model and cross-sectional data of a cohort study. Partial attributable risks have been used to illustrate the proportions of the different risk factors for the attributable risk. In addition we derive standard errors for the attributable risk based on the Taylor series expansion. Since the data of our cohort study was sampled with the same size in each 10 years age stratum which does not reflect the age-structure of the general population, the attributable risk and its standard errors are calculated using an approach that allows the weighting of the data according to population proportions of age. The formula for the standard errors has been evaluated using bootstrap-techniques.

RESULTS

We successfully implemented the method for the estimation of the attributable risk and its standard errors by integrating risk information using data of the HeartScore Germany and cross-sectional data emerging from the Gutenberg Health Study. The attributable risk can now be calculated without using the information of the overall disease rate. The bootstrap method shows, that the formula for the standard errors is useful.

CONCLUSION

Our method allows for the combination of different data sources in order to estimate attributable risks and our formula for the standard errors seems to yield a good approximation. But the validity of our method highly depends on the validity of the underlying data sources.

The social phobia psychotherapy research network. The first multicenter randomized controlled trial of psychotherapy for social phobia: rationale, methods and patient characteristics

This paper presents the Social Phobia Psychotherapy Research Network. The research program encompasses a coordinated group of studies adopting a standard protocol and an agreed-on set of standardized measures for the assessment and treatment of social phobia (SP). In the central project (study A), a multicenter randomized controlled trial, refined models of manualized cognitive-behavioral therapy and manualized short-term psychodynamic psychotherapy are compared in the treatment of SP. A sample of 512 outpatients will be randomized to either cognitive-behavioral therapy, short-term psychodynamic psychotherapy or waiting list. Assessments will be made at baseline, at the end of treatment and 6 and 12 months after the end of treatment. For quality assurance and treatment integrity, a specific project using highly elaborated measures has been established (project Q). Study A is complemented by 4 interrelated add-on projects focusing on attachment style (study B1), on cost-effectiveness (study B2), on variation in the serotonin transporter gene in SP (study C1) and on structural and functional deviations of the hippocampus and amygdala (study C2). Thus, the Social Phobia Psychotherapy Research Network program enables a highly interdisciplinary research into SP. The unique sample size achieved by the multicenter approach allows for studies of subgroups (e.g. comorbid disorders, isolated vs. generalized SP), of responders and nonresponders of each treatment approach, for generalization of results and for a sufficient power to detect differences between treatments. Psychological and biological parameters will be related to treatment outcome, and variables for differential treatment indication will be gained. Thus, the results provided by the network may have an important impact on the treatment of SP and on the development of treatment guidelines for SP.

Improved Postural Control after Behavioural Short Term Intervention in Patients with Psychiatric Dizziness

Background:

Patients with psychiatric dizziness often report subjective instability of stance and gait and fear of falls. They showed increased activity of their body sway in static posturography compared to normals (1, 2). Aim of the present study was to evaluate the efficiency of a behavioural therapy by static posturography.

Methods:

14 patients with psychiatric dizziness were included in the prospective study on static posturography to quantify the postural sway (sway path) during upright stance under different conditions. the psychosomatic examination comprised of standardized interviews (SCID-Interview) and a psychometric examination battery (SCL-90, VSS, VHQ). Results of static posturography were compared to those of an age-matched control group (n=23), baseline measurements were compared to the results after behavioural short term intervention.

Results:

At baseline patients revealed significantly lower sway-path values in the anterior-posterior and lateral planes (p< 0.001 - p=0.042) but significantly elevated values in the vertical plane (p=0.015 - p=0.042). They had to be supported more often in the examination setting to prevent falls (p< 0.001). after the short term intervention therapy a normalization of sway path values was present, especially the increased vertical sway activity was reduced (p=0.028).

Conclusion:

Patients with psychiatric dizziness activate significantly more anti-gravity muscles which reflects a change in postural strategy with an increased “stiffness” and a consecutively higher rate of “falls”. the patient's conscious control of stance augments coactivation of anti-gravity muscles. This typical pattern of postural control could be normalized by a short term behavioural therapy.

Social sex selection and the balance of the sexes: Empirical evidence from Germany, the UK, and the US

Preconception sex selection for nonmedical reasons is one of the most controversial issues in bioethics today. The most powerful objection to social sex selection is based on the assumption that it may severely distort the natural sex ratio and lead to a socially disruptive imbalance of the sexes. Based on representative social surveys conducted in Germany, the United Kingdom, and the United States, this paper argues that the fear of an impending sex ratio distortion is unfounded. Given the predominant preference for a "gender balanced family," a widely available service for social sex selection is highly unlikely to upset the balance of the sexes in Western societies.

Die subjektive Gesundheit älterer Menschen im Spiegel des SF-36

This paper presents data regarding the German version of the SF-36 (Short Form 36 Questionnaire; Bullinger and Kirchberger, 1998) that were obtained from a large community based sample of the German population. Results are reported for the elderly at the age of 60 and older from the German general population (N = 690; 57% female). Presented are the internal consistencies of the scales (Cronbach's Alpha), the intercorrelations of the scales, mean values of the scales separated by sex, age group (60-64 years, 65-69 years, 70-74 years, 75-79 years, 80 years and older) and residence (Eastern and Western Germany) as well as percentile ranks for the whole sample.

Processing of environmental sounds in schizophrenic patients: disordered recognition and lack of semantic specificity

The recognition of environmental sounds is an important feature of higher auditory processing and essential for everyday life. The present study aimed to investigate the potential impairment of this mental function in schizophrenia. This work on immediate sound recognition is complementary to recent studies on auditory linguistic processing. Fifteen schizophrenic patients and 30 control subjects were asked to identify 43 complex environmental sounds from different categories and rate their familiarity when naïve to the sounds. In consecutive experiments, patients and control subjects rated the sounds according to emotional valence and arousal, as well as imageability. In both groups, correct identification of non-verbal sounds was highly associated with familiarity. Statistical analysis by group demonstrated a significantly higher error rate in identifying sounds in patients suffering from schizophrenia compared to healthy control subjects. In contrast, the affective recognition of the complex sounds was preserved in the schizophrenic patients. These results suggest a disturbance of higher-order, auditory mnemonic processing in schizophrenic patients in the non-linguistic domain. We discuss their abnormal responses in the context of recent theories of auditory physiological and semantic processing deficits in schizophrenia.

Attitudes towards preconception sex selection: a representative survey from Germany

Within the next parliamentary term, the German government is expected to replace the current Embryo Protection Act with a new Human Reproductive Technology Act. Before introducing new legislation, policy makers may want to survey public attitudes towards novel applications of reproductive technology. In order to assess opinions and concerns about preconception sex selection for non-medical reasons, a social survey has been conducted in Germany. As a representative sample of the German population, 1005 men and women 18 years and older were asked whether or not preconception sex selection should be made available. Of the respondents, 32% held that sex selection should be strictly prohibited, be it for medical or non-medical reasons, and 54% accepted the use of preconception sex selection for medical purposes. Only a minority of 11% approved of the use of preconception sex selection for non-medical reasons. The widespread opposition to a freely available service for non-medical sex selection is based on several claims: 87% of respondents hold that 'children are a gift and deserve to be loved regardless of any characteristics such as beauty, intelligence or sex'; 79% argue that choosing the sex of children is 'playing God'; 76% are opposed because it is seen as 'unnatural'; 49% are afraid that it is 'skewing the natural sex ratio'; and 40% consider it to be 'sexist'.

Preconception sex selection for non-medical reasons:a representative survey from Germany

BACKGROUND

Preconception sex selection for non-medical reasons raises serious moral, legal and social issues. The main concern is based on the assumption that a freely available service for sex selection will distort the natural sex ratio and lead to a severe gender imbalance. However, for a severe gender imbalance to happen, at least two conditions have to be met. First, there must be a significant preference for children of a particular sex, and second, there must be a considerable demand for preconception sex selection. To ascertain whether or not these two conditions are met, we have conducted a survey in Germany.

METHODS

As a representative sample of the German population, 1094 men and women aged 18-45 years were asked about their gender preferences and whether or not they could imagine selecting the sex of their children through flow cytometric separation of X- and Y-bearing sperm followed by intrauterine insemination.

RESULTS

58% of respondents stated that they do not care about the sex of their offspring. 30% wish to have a family with an equal number of boys and girls. 4% would like to have more boys than girls, 3% more girls than boys, 1% only boys and 1% only girls. For first-borns, however, there is still a preference for boys over girls. While 75.6% claimed to have no gender preference, 14.2% would like their first child to be a boy and 10.1% would like their first child to be a girl. Whereas 6% could imagine taking advantage of preconception sex selection, 92% found this to be out of the question. Even in the hypothetical case that a medication for sex selection were ever to become available, 90% stated that they would not want to use it.

CONCLUSION

Given that a majority does not seem to care about the sex of their offspring and only a minority seem to be willing to select the sex of their children, a freely available service for preconception sex selection for non-medical reasons is rather unlikely to cause a severe gender imbalance in Germany.

Sexuality of the elderly

Partial androgen deficiency of the aging male is associated with symptoms collectively accepted as the andropause syndrome. The underlying hormonal changes, the definition of age-dependent cofactors for changing sexuality, and the data on decreasing erectile function are the main topics of this critical analysis. Alterations in libido, ejaculation and sperm quality also have to be considered in order to define a change in male sexuality as part of the natural process of aging.

Effectiveness of behavioral and psychodynamic in-patient treatment of severe obesity--first results from a randomized study

OBJECTIVE

To compare treatment effectiveness of psychodynamic and behavioral in-patient treatment of patients with severe obesity.

DESIGN

: Randomized longitudinal study of obese patients (BMI> or =35 kg/m(2)) randomly assigned to behavioral or to psychodynamic psychosomatic rehabilitation.

SUBJECTS

Ninety eight, mostly female (88%), obese patients (age 20-64 y, BMI 36-74 kg/m(2)).

MEASUREMENTS

Standardized self-report scales on distress (SCL-90R), eating behavior (FEV), interpersonal problems (IIP), body image (FKB-20), life satisfaction (IRES).

RESULTS

During the 6 weeks of in-patient treatment patients lost an average of 5.4 kg (4.3%) in the behavioral (n=46) and 6.2 kg (4.7%) in the psychodynamic setting (n=52). In both settings, a significant improvement was also found for eating behavior, well-being, body image and life satisfaction. Weight reduction was more pronounced for those with a higher weight at onset, more distress in public at admission, and a longer treatment.

CONCLUSION

Despite considerable differences in the behavioral vs psychodynamic treatment settings, both were equally effective. However, some common treatment elements were perceived differently by patients in the two settings. Analysis of the follow-up data will hopefully provide evidence as to which patients benefit more from which approach.

[Age-related complaints and testosterone deficit from the psychosomatic viewpoint]

Age-related changes in men resemble symptoms of hypogonadism. Although the average levels of testosterone decrease with age, correlations between complaints and testosterone levels are inconsistent and low in aging men. This is related to methodological limitations of studies, the high interindividual variability of testosterone in the aging male, ambiguities of normal values, and numerous determinants (e.g., health status, health behavior) on the level of testosterone. When studying the relationship between decreased testosterone, psychological and physical complaints have to take into consideration a whole array of psychosocial influences (e.g., perception, interpretation, and coping with age-related changes).

Psychosomatic aspects in the diagnosis and treatment of erectile dysfunction

After a critical review of prevalence data, psychosocial determinants and psychosomatic aspects in the diagnosis and treatment of erectile dysfunction are discussed (with reference to age-related changes). Widely used laboratory assessments are responsive to psychological factors (e.g. anxiety). Inclusion of the partner in the diagnostic process may change the clinical picture and the treatment recommendations considerably. As illustrated by penile prosthetis treatment and self-injection of vasoactive substances, acceptance and success of widely used surgical and medical treatments depend largely upon the patient's expectations, and the adaptation of the couple to the procedure. Even in cases with a clear organic pathology, fluctuations in erectile functioning may be attributable to psychological influences. As recent psychotherapeutic and psychoeducational approaches underscore, erectile failure is best conceived as a final common pathway of somatic, lifestyle, psychological and partnership determinants. These should be taken into account in comprehensive diagnostic and treatment formulations if the goal of therapy is not only to produce rigid erections, but to increase sexual satisfaction.

[Work and vocational integration of psychosomatic patients--utilization and indications for a workload tryout program]

The effect of a professional workload test was assessed in a longitudinal study with 80 patients psychosomatic rehabilitation during and following their. In a second study indication criteria were tested with 358 consecutive patients. Participants in the workload program show an improvement of their work ability and job performance according to self-appraisal, superior appraisal and medical assessment. Work ability was still maintained 7 months after treatment. Patients with lasting work disability and unemployment not only show negative work-related attitudes, but also elevated psychological symptoms and a reduced quality of life. The program participants show high levels of psychological strain but also a stronger disposition to change the professional situation. Negative work-related and psychological consequences of lasting disability and unemployment deserve more attention in inpatient psychosomatic treatment.

The b1Sigma+(b0(+)) --> X3Sigma-(X10(+), X21) and a1Delta(a2) --> X21 Transitions of SbF, SbCl, SbBr, and SbI

Emission spectra of the a1Delta(a2) --> X21 and b1Sigma+(b0(+)) --> X3Sigma-(X10(+), X21) transitions of SbF, SbCl, SbBr, and SbI have been observed in the near-infrared spectral region. The antimony halide radicals were generated and excited in a fast-flow system by reaction of antimony vapor (Sbx) with the halides and microwave-discharged oxygen. The NIR chemiluminescence was measured with a Fourier-transform spectrometer equipped with Ge and InSb detectors. The spectra contain the known b1Sigma+(b0(+)) --> X3Sigma-(X10(+), X21) transitions in the range 730-910 nm and the hitherto unknown a1Delta(a2) --> X21 transitions in the range 1600-1900 nm. Vibrational analyses have yielded improved molecular constants for the X10(+), X21, and b0(+) states and the following constants of the a2 states (in cm-1): 121SbF: Te = 6815.6(5), omegae = 615.75(3), omegaexe = 2.62(1); 121Sb35Cl: Te = 6546.3(2), omegae = 379.8(1), omegaexe = 1.20(2); 121Sb79Br: Te = 6496.4(4), omegae = 265.9(2), omegaexe = 0.55(3); 121SbI: Te = 6366.7(3), omegae = 214.20(5), omegaexe = 0.430(9), where the numbers in parentheses are the standard deviations of the parameters.

The b1Sigma+(b0(+)) --> X3Sigma-(X10(+), X21) and a1Delta(a2) --> X21 Transitions of AsI

Emission spectra of the b1Sigma+(b0(+)) --> X3Sigma-(X10(+), X21) and a1Delta(a2) --> X21 transitions of AsI have been measured in the near-infrared spectral region with a Fourier-transform spectrometer. The arsenic iodide radicals were generated and excited in a fast-flow system by reaction of arsenic vapor (Asx) with iodine and microwave-discharged oxygen. The most prominent features in the spectrum are six band sequences of the strong b1Sigma+(b0(+)) --> X3Sigma-(X10(+)) transition in the range 800-900 nm. With much lower intensities the hitherto unknown b1Sigma+(b0(+)) --> X3Sigma-(X21) subsystem and the a1Delta(a2) --> X21 transition near 1660 nm are observed. Vibrational analyses have yielded improved molecular constants for the X10(+) and b0(+) states and first values of the electronic energies and vibrational constants of the X21 and a2 states (in cm-1), X21: Te = 289.8(2), omegae = 255.2(2), omegaexe = 0.68(7), a2: Te = 6305.4(3), omegae = 267.8(1), omegaexe = 0.56(2), where the numbers in parentheses are the standard deviations of the parameters.

Treatment-related stresses and depression in couples undergoing assisted reproductive treatment by IVF or ICSI

The purposes of the study were to compare treatment-related stresses of couples undergoing IVF or ICSI treatment (ejaculated, epididymal or testicular spermatozoa) and to identify sex differences and risk factors for depression. A one-year cohort of couples was retrospectively sent questionnaires on infertility and treatment-related distress and depression (Depression Scale, D-S). Two hundred and eighty-one women and 281 men (61% of those eligible) were included. As determined by analysis of the medical charts, successful couples were more likely to participate. Treatment-related distress was generally higher for women than for men. Treatment by ICSI carried additional burdens for the men: they reported a greater subjective responsibility for the infertility, impact of childlessness on daily life, treatment-related stresses (particularly for MESA/TESE) and time demands. Even when clinical differences between treatments (e.g. age, previous treatments) were controlled statistically, depression scores did not differ. Independent of the treatment, women were significantly more depressed than their age-matched female controls from the general population and their husbands. The men only reported marginally elevated depression scores compared to their controls. Meaningful characteristics were identified that could guide clinicians to give psychological support to those couples at risk for depression, e.g. an unsuccessful treatment outcome, repeated treatment cycles, a low socioeconomic status, foreign nationality, or, for women, a lack of partner support.
