Abstract
BACKGROUND Hidradenitis suppurativa (HS) is an inflammatory disease of the inverse skin regions with an age peak at around 40 years and an estimated prevalence of 1%. Nodules and abscesses can develop into fistules and scarring, which cause severe pain. HS is a progressive, life-defining disease that leads to physical limitations, inability to work, and social isolation. There is still little data on the drivers of disease severity and burden. METHOD The cross-sectional study is based on the baseline data of 553 participants of the health care research project "EsmAiL," which was carried out as a multicenter randomized controlled trial. It included adult HS-patients presenting with at least three inflammatory lesions and at least a moderate impact on quality of life. RESULTS Disease activity increases with age. Men are more severely affected than women but feel less burdened. Obesity negatively influences disease activity and disease burden. Affected individuals have a higher level of education than the age adjusted population, but the unemployment rate is significantly higher. Disease activity significantly reduces quality of life and promotes depression and anxiety. CONCLUSIONS HS is a severe and debilitating dermatosis. As a result of the well-established factors involved, HS requires a multi-causal approach to management, in addition to medical and surgical treatment. This must take into account all available therapeutic options, as well as patient education to reduce risk factors and pain, and psychological support. HS requires interdisciplinary and multi-professional care. To prevent disease progression, a structured treatment plan is needed.

Abstract
OBJECTIVE Body composition assessment derived from cross-sectional imaging has shown promising results as a prognostic biomarker in several tumor entities. Our aim was to analyze the role of low skeletal muscle mass (LSMM) and fat areas for prognosis of dose-limiting toxicity (DLT) and treatment response in patients with primary central nervous system lymphoma (PCNSL). METHODS Overall, 61 patients (29 female patients, 47.5%) with a mean age of 63.8 ± 12.2 years, range 23-81 years, were identified in the data base between 2012 and 2020 with sufficient clinical and imaging data. Body composition assessment, comprising LSMM and visceral and subcutaneous fat areas, was performed on one axial slice on L3-height derived from staging computed tomography (CT) images. DLT was assessed during chemotherapy in clinical routine. Objective response rate (ORR) was measured on following magnetic resonance images of the head accordingly to the Cheson criteria. RESULTS Twenty-eight patients had DLT (45.9%). Regression analysis revealed that LSMM was associated with objective response, OR = 5.19 (95% CI 1.35-19.94, p = 0.02) (univariable regression), and OR = 4.23 (95% CI 1.03- 17.38, p = 0.046) (multivariable regression). None of the body composition parameters could predict DLT. Patients with normal visceral to subcutaneous ratio (VSR) could be treated with more chemotherapy cycles compared to patients with high VSR (mean, 4.25 vs 2.94, p = 0.03). Patients with ORR had higher muscle density values compared to patients with stable and/or progressive disease (34.46 ± vs 28.18 ± HU, p = 0.02). CONCLUSIONS LSMM is strongly associated with objective response in patients with PCNSL. Body composition parameters cannot predict DLT. CLINICAL RELEVANCE STATEMENT Low skeletal muscle mass on computed tomography (CT) is an independent prognostic factor of poor treatment response in central nervous system lymphoma. Analysis of the skeletal musculature on staging CT should be implemented into the clinical routine in this tumor entity. KEY POINTS • Low skeletal muscle mass is strongly associated with the objective response rate. • No body composition parameters could predict dose-limiting toxicity.

Abstract
INTRODUCTION Hidradenitis suppurativa (HS) is a chronic inflammatory disorder of the pilosebaceous unit, often affecting and deforming intimate regions. HS is associated with severe pain, pruritus, and constant, purulent, malodorous discharge expected to impair sexual health of patients. METHODS We performed a cross-sectional, multicentric study involving 199 German patients from the health services research project "Epidemiology and Care in Acne inversa (EpiCAi)." The sexual health, HS severity, and quality of life of the studied group were evaluated using a specially designed questionnaire. RESULTS Regardless of gender, HS has an enormous impact on patients' sexual health. The patients scored, on average, 28.8 ± 5.3 points on the Relation and Sexuality Scale (RSS). Multiple linear regression revealed that females and patients with Hurley III stage had higher sexual dysfunction (p = 0.012). Sexual dysfunction is associated with pain (β = 0.25), the number of active lesions, the affected areas (β = 0.14), and psychosocial aspects, including low quality of life (β = 0.404), stigmatization (β = 0.411), depression (β = 0.413), and anxiety (β = 0.300). Patients already see a substantial decrease in sexual frequency in the early stages of HS, while functional impairment and fear increase with the severity of the disease. CONCLUSION Sexual health and management of its dysfunctions should be part of a holistic approach to HS patients.

Abstract
BACKGROUND Hidradenitis suppurativa (HS) is a chronic inflammatory skin disease affecting approximately 1% of the population. The patient journey through the German health care system leads to high disease burden and substantial treatment costs. The EsmAiL study showed that an innovative, interprofessional, multimodal care-concept reduces disease activity and burden of HS compared to standard care. This paper examines the costs of treating HS in Germany and compares them with those of the innovative care concept implemented in EsmAiL. METHODS EsmAiL was a two-arm, multicenter, prospective randomized controlled trial including 553 adults with HS. The study was registered in the German Clinical Trials Registry (DRKS00022135). The control group (CG) remained in standard care, whereas the intervention group (IG) was referred to specialized so-called 'acne-inversa-centres (AiZ)' where patients were treated with a structured, interdisciplinary approach. The present paper analyses the treatment costs for a subpopulation based on health insurance cost data from the two largest German health insurers. Quality-Adjusted Life Years (QALY) was assessed based on Dermatology Life Quality Index (DLQI). RESULTS Total annual treatment costs per patient were €3,966.07 in standard care (n = 89) and €3,974.37 in the innovative care (n = 93). The costs per additional QALY amounted to €12,698.72 in the IG. Given the conventional and established threshold of €22,600 to €33,900 per QALY, the innovative treatment in AiZ proved to be cost-effective. CONCLUSION Treatment costs of HS are substantial and increase with disease severity. The new form of care is cost-effective and is expected to decrease costs in the long run.

Abstract
OBJECTIVES Low skeletal muscle mass (LSMM) predicts relevant clinical outcomes in oncologic patients. The purpose of this study was to perform a meta-analysis of data regarding associations between LSMM and treatment response (TR) in oncology. METHODS MEDLINE, Cochrane, and SCOPUS databases were screened for relationships between LSMM and TR in oncologic patients up to November 2022. Overall, 35 studies met the inclusion criteria. The meta-analysis was performed using RevMan 5.4 software. RESULTS The collected 35 studies comprised 3858 patients. In 1682 patients (43.6%), LSMM was diagnosed. In the overall sample, LSMM predicted a negatively objective response rate (ORR), OR = 0.70, 95% CI = (0.54-0.91), p = 0.007, and disease control rate (DCR), OR = 0.69, 95% CI = (0.50-0.95), p = 0.02. In the curative setting, LSMM predicted a negatively ORR, OR = 0.24, 95% CI = (0.12-0.50), p = 0.0001, but not DCR, OR = 0.60, 95% CI = (0.31-1.18), p = 0.14. In palliative treatment with conventional chemotherapies, LSMM did not predict ORR: OR = 0.94, 95% CI (0.57-1.55), p = 0.81, and DCR: OR = 1.13, 95% CI (0.38-3.40), p = 0.82. In palliative treatment with tyrosine kinase inhibitors (TKI), LSMM did not predict TR: ORR, OR = 0.74, 95% CI (0.44-1.26), p = 0.27, and DCR, OR = 1.04, 95% CI (0.53-2.05), p = 0.90. In palliative immunotherapy, LSMM tended to predict ORR, OR = 0.74, 95% CI = (0.54-1.01), p = 0.06, and predicted DCR, OR = 0.53, 95% CI = (0.37-0.76), p = 0.0006. CONCLUSION LSMM is a risk factor for poor TR in curative chemotherapy in the adjuvant and/or neoadjuvant setting. LSMM is a risk factor for treatment failure in treatment with immunotherapy. Finally, LSMM does not influence TR in palliative treatment with conventional chemotherapy and/or TKIs. KEY POINTS • Low skeletal muscle mass (LSMM) predicts treatment response (TR) to chemotherapy in the adjuvant and/or neoadjuvant setting. • LSMM predicts TR in immunotherapy. • LSMM does not influence TR in palliative chemotherapy.

Abstract
The use of hazard ratios as the standard treatment effect estimators for randomized trials with time-to-event outcomes has been the subject of repeated criticisms in recent years, e.g., for its non-collapsibility or with respect to (causal) interpretation. Another important issue is the built-in selection bias, which arises when the treatment is effective and when there are unobserved or not included prognostic factors that influence time-to-event. In these cases, the hazard ratio has even been termed "hazardous" because it is estimated from groups that increasingly differ in their (unobserved or omitted) baseline characteristics, yielding biased treatment estimates. We therefore adapt the Landmarking approach to assess the effect of ignoring a gradually increasing proportion of early events on the estimated hazard ratio. We propose an extension called "Dynamic Landmarking". This approach is based on successive deletion of observations, refitting Cox models and balance checking of omitted but observed prognostic factors, to obtain a visualization that can indicate built-in selection bias. In a small proof-of-concept simulation, we show that our approach is valid under the given assumptions. We further use "Dynamic Landmarking" to assess the suspected selection bias in the individual patient data sets of 27 large randomized clinical trials (RCTs). Surprisingly, we find no empirical evidence of selection bias in these RCTs and thus conclude that the supposed bias of the hazard ratio is of little practical relevance in most cases. This is mainly due to treatment effects in RCTs being small and the patient populations being homogeneous, e.g., due to inclusion and exclusion criteria.

Abstract
BACKGROUND Hidradenitis suppurativa (HS) is an inflammatory disease of the inverse skin regions that occurs in young women, in particular, and affects approximately 1% of the population. Outpatient care is often inadequate and usually cannot prevent progression. OBJECTIVES To evaluate in the EsmAiL ('Evaluation eines strukturierten und leitlinienbasierten multmodalen Versorgungskonzepts für Menschen mit Akne inversa') trial whether an innovative care concept can decrease disease activity and burden, and improve patient satisfaction. METHODS EsmAiL was conducted as a two-arm, multicentre, prospective, randomized controlled trial that included 553 adults with HS. Inclusion criteria were a minimum of three inflammatory lesions and at least a moderate impact of the disease on quality of life. The control group (CG) remained under standard care, while patients in the intervention group (IG) were treated according to a trial-specific, multimodal concept. The primary endpoint was the absolute change in International Hidradenitis Suppurativa Severity Score System (IHS4). RESULTS In total, 274 patients were randomized to the IG and 279 to the CG. Altogether, 377 attended the final assessment after 12 months of intervention. Participants in the IG (n = 203) achieved a mean improvement in IHS4 of 9.3 points, while the average decrease in IHS4 in patients in the CG (n = 174) was 5.7 points (P = 0.003). Patients treated under the new care concept also reported a statistically significantly higher decrease in pain, Dermatology Life Quality Index and Hospital Anxiety and Depression Scale scores compared with those in the CG (P < 0.001). Patient satisfaction was also statistically significantly higher in the IG compared with the CG (P < 0.001). CONCLUSIONS The establishment of standardized treatment algorithms in so-called 'acne inversa centres' in the ambulatory setting has a substantial, positive impact on the course of HS and significantly improves patient satisfaction.

The pandemic, however, has also raised awareness of the danger posed by the family of coronaviruses, of which 7 are known to infect humans and dozens have been identified in reservoir species, such as bats, rodents, or livestock. To facilitate understanding the commonalities and specifics of coronavirus infections and aspects of viral biology that determine their level of lethality to the human host, we have generated a collection of freely available clones encoding nearly all human coronavirus proteins known to date. We hope that this flexible, Gateway-compatible vector collection will encourage further research into the interactions of coronaviruses with their human host, to increase preparedness for future zoonotic viral outbreaks.

Abstract
Understanding the mechanisms of coronavirus disease 2019 (COVID-19) disease severity to efficiently design therapies for emerging virus variants remains an urgent challenge of the ongoing pandemic. Infection and immune reactions are mediated by direct contacts between viral molecules and the host proteome, and the vast majority of these virus-host contacts (the 'contactome') have not been identified. Here, we present a systematic contactome map of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) with the human host encompassing more than 200 binary virus-host and intraviral protein-protein interactions. We find that host proteins genetically associated with comorbidities of severe illness and long COVID are enriched in SARS-CoV-2 targeted network communities. Evaluating contactome-derived hypotheses, we demonstrate that viral NSP14 activates nuclear factor κB (NF-κB)-dependent transcription, even in the presence of cytokine signaling. Moreover, for several tested host proteins, genetic knock-down substantially reduces viral replication. Additionally, we show for USP25 that this effect is phenocopied by the small-molecule inhibitor AZ1. Our results connect viral proteins to human genetic architecture for COVID-19 severity and offer potential therapeutic targets.

Abstract
RATIONALE AND OBJECTIVES To evaluate the impact of low skeletal muscle mass in patients with COVID-19 on relevant outcomes like 30-day mortality, need for intubation and need for intensive care unit admission. MATERIALS AND METHODS For this study, data from six centers were acquired. The acquired sample comprises 1138 patients. There were 547 women (48.1%) and 591 men (51.9%) with a mean age of 54.5 ± 18.8 years; median age, 55 years; range, 18-84 years). In every case, thoracic CT without intravenous application of contrast medium was performed. The following parameters of the pectoralis muscles were estimated: muscle area as a sum of the bilateral areas of the pectoralis major and minor muscles, muscle density, muscle index (PMI) (pectoralis muscle area divided by the patient's body height square) as a ratio pectoralis major and minor muscles divided by the patient's body height2, and muscle gauge as PMI x muscle density. RESULTS Overall, 220 patients (19.33%) were admitted to the intensive care unit. In 171 patients (15.03%), mechanical lung ventilation was performed. Finally, 154 patients (13.53%) died within the observation time of 30-day. All investigated parameters of pectoralis muscle were lower in the patients with unfavorable courses of Covid-19. All pectoralis muscle parameters were associated with 30-day mortality in multivariate analyses adjusted for age and sex: pectoralis muscle area, HR = 0.93 CI 95% (0.91-0.95) p < 0.001; pectoralis muscle density, HR = 0.94 CI 95% (0.93-0.96) p < 0.001; pectoralis muscle index, HR = 0.79 CI 95% (0.75-0.85) p < 0.001, pectoralis muscle gauge, HR = 0.995 CI 95% (0.99-0.996) p < 0.001. CONCLUSION in COVID-19, survivors have larger areas and higher index, gauge and density of the pectoralis muscles in comparison to nonsurvivors. However, the analyzed muscle parameters cannot be used for prediction of disease courses.

Abstract
Low skeletal muscle mass as a proxy parameter for sarcopenia acts as a non-invasive imaging marker that is associated with poor prognosis in numerous types of cancer. The present study aimed to assess the influence of body composition parameters on overall survival (OS) and progression free survival (PFS) in patients diagnosed with primary central nervous system lymphoma (PCNSL). A total of 98 patients with PCNSL treated at University Hospital Magdeburg (Magdeburg, Germany) from 2013–2019 were retrospectively studied. Patients with a pre-treatment staging computed tomography (CT) scan that included the third lumbar vertebra were reviewed for analysis. Skeletal muscle area (SMA), skeletal muscle index (SMI), mean muscle density and skeletal muscle gauge (SMG) were measured on the CT scan prior to treatment. Parameters were associated with OS and PFS. Overall, 72 patients were included in the present study. Results of the present study demonstrated that the median OS was 10 months (range, 1–181 months), and 37 patients (51.4%) presented with sarcopenia. Moreover, the median OS was 7 months in the sarcopenic group and 32 months in the non-sarcopenic group. Results of the present study further illustrated that SMI, SMA, density and SMG did not exert a significant effect on OS. Notably, the median PFS was 2.5 months in the low SMI group and 10 months in the normal SMI group. Body composition parameters did not exert a significant effect on PFS. Overall, the results of the present study demonstrated that sarcopenia was not a risk factor for decreased OS or PFS in patients with PCNSL undergoing systemic treatment.

Abstract
Purpose To assess the influence of low skeletal muscle mass (LSMM) on post-operative complications in patients with hepatic malignancies grade (Clavien Dindo ≥ 3) undergoing resection. Methods MEDLINE, Cochrane, and SCOPUS databases were screened for associations between sarcopenia and major post-operative complications (≥ grade 3 according to Clavien-Dindo classification) after resection of different malignant liver tumors. RevMan 5.3 software was used to perform the meta-analysis. The methodological quality of the included studies was assessed according to the QUIPS instrument. Results The analysis included 17 studies comprising 3157 patients. Subgroup analyses were performed for cholangiocarcinoma (CCC), colorectal cancer (CRC) liver metastases, and hepatocellular carcinoma (HCC). LSMM as identified on CT was present in 1260 patients (39.9%). Analysis of the overall sample showed that LSMM was associated with higher post-operative complications grade Clavien Dindo ≥ 3 (OR 1.56, 95% CI 1.25–1.95, p < 0.001). In the subgroup analysis, LSMM was associated with post-operative complications in CRC metastases (OR 1.60, 95% CI 1.11–2.32, p = 0.01). In HCC and CCC sub-analyses, LSMM was not associated with post-operative complications in simple regression analysis. Conclusion LSMM is associated with major post-operative complications in patients undergoing surgery for hepatic metastases and it does not influence major post-operative complications in patients with HCC and CCC.

Abstract
PURPOSE Psychometric properties and clinical sensitivity of brief self-rated dimensional scales to supplement categorical diagnoses of anxiety disorders in the DSM-5 were recently demonstrated in a German treatment seeking sample of adults. The present study aims to demonstrate sensitivity of these scales to clinical severity levels. METHODS The dimensional scales were administered to 102 adults at a university outpatient clinic for psychotherapy. Diagnostic status was assessed using the Munich-Composite International Diagnostic Interview. To establish a wide range of clinical severity, we considered subthreshold (n=83) and threshold anxiety disorders (n=49, including Social Phobia, Specific Phobia, Agoraphobia, Panic Disorder, and Generalized Anxiety Disorder). RESULTS Individuals with either subthreshold or threshold anxiety disorder scored higher on all dimensional scales relative to individuals without anxiety. In addition, individuals with a threshold anxiety disorder scored higher on the dimensional scales than individuals with a subthreshold anxiety disorder (except for specific phobia). Disorder-related impairment ratings, global functioning assessments and number of panic attacks were associated with higher scores on dimensional scales. Findings were largely unaffected by the number of anxiety disorders and comorbid depressive disorders. CONCLUSION The self-rated dimensional anxiety scales demonstrated sensitivity to clinical severity, and a cut-off based on additional assessment of impairment and distress may assist in the discrimination between subthreshold and threshold anxiety disorders. Findings suggest further research in various populations to test the utility of the scales for use in DSM-5.

Abstract
Dopamine-beta-hydroxylase (DbetaH) catalyzes the conversion of dopamine to norepinephrine in central noradrenergic and adrenergic neurons and thus is critically involved in the biosynthesis of catecholamines. There are equivocal findings concerning the question whether or not DssH activity levels are altered in affective disorders or in subtypes of affective disorders. Moreover, information about the role of dopamine beta-hydroxylase (DBH) genotype, which explains a large part of the variance of enzymatic activity, in affective disorders and personality dimensions is limited. To resolve these inconsistencies, association tests were performed using four independent samples, healthy volunteers (N = 387), patients with affective disorders (N = 182), adult attention deficit hyperactivity disorder (ADHD) patients (N = 407), and patients with personality disorders (N = 637). In the latter two samples, the revised NEO personality inventory (NEO-PI-R) was administered. All participants were genotyped for a putatively functional single nucleotide polymorphism (C-1021T, rs1611115). No differences in DBH C-1021T genotype distribution were observed between patients with affective disorders and healthy control subjects. Also when the patient sample was divided into uni- and bipolar patients versus controls, no significant differences emerged. Furthermore, no clear-cut association was detected between the TT genotype and personality disorder clusters while there was a significant association with adult ADHD. However, personality disorder patients carrying the DBH TT genotype exhibited higher neuroticism and novelty seeking scores as compared to individuals with the CC or CT genotype. Analyses on the level of the neuroticism and novelty seeking subscales revealed that the DBH TT genotype was primarily associated with personality features related to impulsiveness and aggressive hostility. Also adult ADHD patients carrying the homozygous TT genotypes displayed by significantly increased neuroticism scores; when both personality disorder and adult ADHD patient were analyzed together, TT carriers also displayed by significantly lower conscientiousness levels. Our results thus do not implicate the DBH C-1021T polymorphism in the pathophysiology of depressive disorders or personality disorders, yet homozygosity at this locus appears to increase the risk towards personality traits related to impulsiveness, aggression and related disease states, namely adult ADHD. These data argue for a dimensional rather than categorical effect of genetic variance in DBH activity; accordingly, the inconsistency of previous findings concerning DbetaH levels in affective disorders might be caused by the underlying association of the TT genotype at DBH-1021 with impulsive personality traits.

Abstract
The gaseous messenger NO has repeatedly been suggested to play a role in the pathogenesis of psychoses. Following a pilot study, we investigated whether the number of nitrinergic neurons in the putamen of patients suffering from schizophrenia, bipolar disorder or major depression is altered. Post-mortem striatum sections of 15 brains from patients with either disease were examined by NADPH-diaphorase staining, which selectively labels NO synthase-positive interneurons. Quantification of these cells revealed significantly lower numbers of NO synthase-containing neurons in the putamen of schizophrenic patients. Our results suggest that striatal nitrinergic interneurons are involved in the pathophysiology of at least some forms of schizophrenia, such as e.g. catatonic schizophrenia.

Abstract
The number of foreign bodies remaining in the patient after a surgical procedure is presumably higher than mentioned in the literature. According to US insurance statistics, the incidence amounts to 1 in 1,500 surgical procedures. As a basic principle--also from the legal aspect--it is necessary to determine whether a foreign body was left in situ accidentally (i.e. due to a material fault) or if it was simply forgotten. In 70% of cases, fabric items (e.g. swabs etc.) are left behind, while around 30% are metal objects. A particularly high risk is seen in emergency settings, in unexpected changes in the surgical procedure, or for patients with a high body mass index. The outcome for the patient differs depending on the nature of the object left behind and the individual patient's situation. Usually, metal items cause more acute clinical symptoms at an earlier time after the operation. Fabric items tend to induce, in the absence of primary contamination, a chronic progression of symptoms over several years. Reoperation has a high mortality (between 11% and 35%). Precautions in terms of risk management have to be established and need to be strictly respected, especially in high risk settings. Visually or acoustically controlled monitoring before wound-closure are recommended to eliminate "human error" as thoroughly as possible.

Abstract
BACKGROUND Polymorphisms in the human frizzeled-3 (FZD3) gene have been associated with schizophrenia in an Asian population sample. However, this finding could not be confirmed in subsequent studies investigating other populations. Here we attempted to replicate this finding in a sample of 192 German chronically ill schizophrenic subjects. METHODS Three single nucleotide polymorphisms in the FZD3 gene have been genotyped by primer extension and MALDI-TOF measurement. Subsequently, associations for single markers as well as haplotypes were tested. RESULTS In German patients, neither single markers nor haplotypes in FZD3 were associated with schizophrenia. Further exploratory analyses using a different diagnostic approach did also not yield significant results. CONCLUSIONS FZD3 is unlikely to play a role in the genetic predisposition towards schizophrenia in the Caucasian population.

Abstract
Anxiety-related behaviors are closely linked to neural circuits relaying fear-specific information to the amygdala. Many of these circuits, like those underlying processing of innate fear, are remarkably well understood. Recent imaging studies have contributed to this knowledge by discriminating more detailed corticoamygdalar associations mediating processing fear and anxiety. However, little is known about the underlying molecular mechanisms. We used the acoustic startle paradigm to investigate the impact of molecular genetic variation of serotonergic function on the acoustic startle response and its fear potentiation. Startle magnitudes to noise bursts as measured with the eye blink response were recorded in 66 healthy volunteers under four conditions: presenting unpleasant and pleasant affective pictures as well as neutral pictures, and presenting the startle stimulus without additional stimuli as a baseline. Subjects were genotyped for functional polymorphism in the transcriptional control region of the serotonin transporter gene (5-hydroxytryptamine transporter gene-linked region: 5-HTTLPR). Analyses of variance revealed a significant effect of 5-HTTLPR on overall startle responses across conditions. Carriers of the short (s) allele exhibited stronger startle responses than l/l homozygotes. However, we could not confirm our hypothesis of enhanced fear potentiation of the startle in s allele carriers. In conclusion, the results provide first evidence that the startle response is sensitive to genetic variation in the serotonin pathway. Despite some issues remaining to be resolved, the startle paradigm may provide a valuable endophenotype of fear processing and underlying serotonergic influences.

Abstract
The phenomenon of adult neurogenesis (AN), that is, the generation of functional neurons from neural stem cells in the dentate gyrus of the hippocampus, has attracted remarkable attention, especially as it was shown that this process is also active in the human brain. Based on animal studies, it has been suggested that reduced AN is implicated in the etiopathology of psychiatric disorders, and that stimulation of AN contributes to the mechanism of action of antidepressant therapies. As data from human post-mortem brain are still lacking, we investigated whether the first step of AN, that is, the level of neural stem cell proliferation (NSP; as quantified by Ki-67 immunohistochemistry), is altered in tissue from the Stanley Foundation Neuropathology Consortium comprising brain specimens from patients with bipolar affective disorder, major depression, schizophrenia as well as control subjects (n=15 in each group). The hypothesis was that stem cell proliferation is reduced in affective disorders, and that antidepressant treatment increases NSP. Neither age, brain weight or pH, brain hemisphere investigated nor duration of storage had an effect on NSP. Only in bipolar disorder, post-mortem interval was a significant intervening variable. In disease, onset of the disorder and its duration likewise did not affect NSP. Also, cumulative lifetime dose of fluphenazine was not correlated with NSP, and presence of antidepressant treatment did not result in an increase of NSP. Concerning the different diagnostic entities, reduced amounts of newly formed cells were found in schizophrenia, but not in major depression. Our findings suggest that reduced NSP may contribute to the pathogenesis of schizophrenia, whereas the rate of NSP does not seem to be critical to the etiopathology of affective disorders, nor is it modified by antidepressant drug treatment.

Abstract
Nitric oxide (NO) is a gaseous neurotransmitter thought to play important roles in several behavioral domains. On a neurobiological level, NO acts as the second messenger of the N-methyl-D-aspartate receptor and interacts with both the dopaminergic as well as the serotonergic system. Thus, NO is a promising candidate molecule in the pathogenesis of endogenous psychoses and a potential target in their treatment. Furthermore, the chromosomal locus of the gene for the NO-producing enzyme NOS-I, 12q24.2, represents a major linkage hot spot for schizophrenic and bipolar disorder. To investigate whether the gene encoding NOS-I (NOS1) conveys to the genetic risk for those diseases, five NOS1 polymorphisms as well as a NOS1 mini-haplotype, consisting of two functional polymorphisms located in the transcriptional control region of NOS1, were examined in 195 chronic schizophrenic, 72 bipolar-I patients and 286 controls. Single-marker association analysis showed that the exon 1c promoter polymorphism was linked to schizophrenia (SCZ), whereas synonymous coding region polymorphisms were not associated with disease. Long promoter alleles of the repeat polymorphism were associated with less severe psychopathology. Analysis of the mini-haplotype also revealed a significant association with SCZ. Mutational screening did not detect novel exonic polymorphisms in patients, suggesting that regulatory rather than coding variants convey the genetic risk on psychosis. Finally, promoter polymorphisms impacted on prefrontal functioning as assessed by neuropsychological testing and electrophysiological parameters elicited by a Go-Nogo paradigm in 48 patients (continuous performance test). Collectively these findings suggest that regulatory polymorphisms of NOS1 contribute to the genetic risk for SCZ, and modulate prefrontal brain functioning.

Abstract
OBJECTIVE Association between the low-activity variant of a polymorphism in the transcriptional control region of the serotonin transporter (5-HTTLPR) and neuroticism or harm avoidance was found in several but not all studies. The authors analyzed the influence of 5-HTTLPR variants on personality disorders. METHOD Patients with personality disorders (N=320) and healthy volunteers (N=281) were studied with the Revised NEO Personality Inventory and the Tridimensional Personality Questionnaire. All were genotyped for 5-HTTLPR variants. RESULTS No differences in 5-HTTLPR genotype distribution were detected between patients with cluster B and C personality disorders and comparison subjects. In contrast, among patients with a cluster C diagnosis, carriers of the low-activity short allele of the 5-HTTLPR exhibited higher neuroticism scores than noncarriers. CONCLUSIONS These findings support the notion that there is no general association between the 5-HTTLPR and anxiety-related traits and that differential gene effects and/or gene-by-environment interactions are likely operative in distinct clinical subpopulations.

Abstract
The intensity dependence of the auditory evoked potential (AEP) has been suggested as an indicator of central serotonergic function, a strong intensity dependence presumably reflecting low serotonergic activity. As individual differences in serotonergic neurotransmission can be accounted for in part by genetic variation in genes of the serotonergic pathway, we investigated whether a functional polymorphism in the promoter region of the serotonin transporter gene (5-HTTLPR) is associated with the AEP intensity dependence. Because dopaminergic influences on the intensity dependence have also been reported, we furthermore explored the role of a functional polymorphism in the dopamine D4 receptor gene (DRD4 exon III) in the modulation of the AEP intensity dependence. AEPs to tones of six intensity levels were recorded from 60 healthy young individuals, and N1/P2 linear as well as median slopes at central electrode sites were computed as measures of the AEP intensity dependence. Analyses of variance showed that there was a significant effect of the 5-HTTLPR on the AEP intensity dependence. Individuals with the ll genotype exhibited a stronger intensity dependence compared to individuals with the ls genotype. This effect was even more pronounced when DRD4 exon III was considered in the analyses. In conclusion, these findings provide further evidence for a role of serotonergic neurotransmission in the modulation of the AEP intensity dependence. The results also point to possible dopaminergic influences on the AEP intensity dependence.

Abstract
The 5-HT1A receptor plays a critical role in the pathophysiology of anxiety and depression as well as in the mode of action of anxiolytic and antidepressant drugs. Human 5-HT1A gene transcription is modulated by a common C-1016G single nucleotide polymorphism (SNP) in its upstream regulatory region. In the present study, we evaluated the role of the HTR1A-1019 polymorphism in the modulation of individual differences in personality traits by an association study of a sample of healthy volunteers. Personality traits were assessed with two different methods, NEO personality inventory (NEO-PI-R) and Tridimensional Personality Questionnaire (TPQ). There was a significant effect of the HTR1A-1019 polymorphism on NEO Neuroticism with carriers of the G allele showing higher scores than individuals homozygous for the C variant. The effect was primarily due to associations with the Neuroticism facets Anxiety and Depression. Carriers of the G allele also exhibited higher TPQ Harm Avoidance scores. Our findings indicate a role of allelic variation in 5-HT1A receptor expression in the development and modulation of anxiety- and depression-related personality traits.

Abstract
Since the observation of an association between the dopamine D4 receptor (DRD4) exon III polymorphism and the temperament trait of Novelty Seeking,1 replication studies have yielded both positive2-5 and negative6-12 results. This raised the question whether the initial findings must be regarded as false positives.13 However, demographic or methodological differences between studies may have obscured the small effect of the DRD4 polymorphism on Novelty Seeking.14 Examination of clinical or older cohorts may have led to an underestimation of possible associations due to a restricted variation of Novelty Seeking in these cohorts. The use of different questionnaires provides another source of variation. In order to replicate the initial findings as precisely as possible, a cohort of 136 healthy, young volunteers was genotyped, and Novelty Seeking was ascertained using the TPQ.15,16 In addition, further aspects of novelty seeking behavior have been ascertained through additional trait measures. We could observe the reported association between long DRD4 alleles and significantly elevated scores (age- and sex-residualized) on the TPQ-Novelty Seeking total scale as well as on two of the subscales, Exploratory Excitability and Extravagance. The results provide further confirmation for the role of the DRD4 exon III polymorphism in modulation of Novelty Seeking. In addition, the pattern of associations between the polymorphism and other scales suggests that this polymorphism has its effect on exploratory, extravagant, and extraverted, rather than on impulsive and monotony-avoidant subtypes of Novelty Seeking.

Abstract
AIMS/HYPOTHESIS Thiazolidinediones, a new class of insulin sensitizers, up-regulate the expression of uncoupling protein 2 in rodent adipocytes. It is not known, however, whether thiazolidinediones influence uncoupling protein 2 expression in human adipocytes. We therefore investigated the effect of these drugs on uncoupling protein 2 expression in the recently immortalized human PAZ6 adipocyte cell line. METHODS Immortalized human PAZ6 preadipocytes were differentiated into adipocytes in the presence or absence of thiazolidinediones. The effect of the drugs on uncoupling protein 2 expression and adipocyte differentiation was measured by reverse transcription-polymerase chain reaction of mRNA of uncoupling protein 2 and of five adipocyte differentiation markers. RESULTS When cells were differentiated 15 days in the presence of thiazolidinediones, uncoupling protein 2 expression was 2.1-fold higher than in the absence of the drugs. The expression of five adipocyte differentiation markers was, however, also increased by thiazolidinediones. Short-term incubation for 4 and 24 h with thiazolidinediones increased uncoupling protein 2 expression 1.35-fold and 2.3-fold, respectively. The expression of adipocyte markers studied in parallel was also augmented. CONCLUSION/INTERPRETATION Thiazolidinediones rapidly increase the expression of uncoupling protein 2 in human PAZ6 adipocytes but the increase of uncoupling protein 2 expression is always associated with an augmentation of the expression of all adipocyte markers studied in parallel. This indicates that the effect of thiazolidinediones on uncoupling protein 2 mRNA reflects a general increase in adipocyte differentiation rather than a specific augmentation of uncoupling protein 2 gene expression.

Abstract
BACKGROUND The family of uncoupling proteins is thought to play an important role in the regulation of energy metabolism by uncoupling the respiratory chain reactions from ATP synthesis. The recently discovered uncoupling protein 2 (UCP2) is upregulated in genetically obese rodent models and during long term high fat feeding. AIM We have examined the UCP2 mRNA levels in liver, heart and white adipose tissue (WAT) of obese ventromedial hypothalamus (VMH)-lesioned rats, during the dynamic and the early stage of the static phase of obesity, before the appearance of most of the metabolic perturbations associated with long term established obesity. RESULTS The amount of UCP2 mRNA was not increased in any tissue of VMH-lesioned rats relative to control animals during the dynamic phase nor during the early static phase of obesity. CONCLUSION These results indicate that in the rat, obesity does not necessarily lead to an increase in UCP2 expression and suggest that the up-regulation of UCP2 described in other models may be secondary to metabolic perturbations, rather than to a direct adaptative response to the increased adipose tissue content of the organism.

Abstract
OBJECTIVES The study was designed to evaluate the functional impact of nitric oxide (NO) generation within the myocardium on cardiac contraction in the failing human heart. BACKGROUND Heart failure is associated with activation of cytokines and expression of inducible nitric oxide synthase (NOS II), which generates NO from L-arginine. Nitric oxide has been shown to modulate myocardial performance, raising the possibility that cardiac generation of NO by NOS II modulates cardiac contraction in the failing human heart. METHODS Left ventricular (LV) tissue of 24 patients with end-stage heart failure was obtained during cardiac transplantation. Gene expression of NOS II and endothelial NO-synthase (NOS III) was quantified by competitive reverse transcription-polymerase chain reaction and compared to tissues of five nonfailing donor hearts. Nitric oxide synthase II activity was determined by citrulline assay and related to changes in force of contraction induced by the beta-adrenergic agonist isoproterenol, NO-donors and/or N-mono-methyl-L-arginine (L-NMMA), an inhibitor of NOS. RESULTS While NOS III mRNA was reduced in failing hearts, NOS II mRNA was increased in failing LV tissue and correlated with NOS II activity. High NOS II activity was associated with early relaxation and impaired responsiveness to beta-adrenergic stimulation, that is, the inotropic response to isoproterenol in failing hearts was inversely related to NOS II activity (r=0.61, p < 0.005). Nitric oxide donors or L-NMMA did not affect myocardial performance in failing hearts at baseline. However, L-NMMA enhanced the positive inotropic response to beta-adrenergic stimulation in failing hearts with high NOS II activity. Nitric oxide donors attenuated the isoproterenol-induced increase in force of contraction of failing hearts. CONCLUSIONS Cardiac production of NO by NOS II attenuates the positive inotropic effects of beta-adrenergic stimulation and hastens relaxation in failing human hearts.
