Background There is evidence for two different types and/or sources of mental illness stigma, namely the display of psychiatric symptoms and the use of psychiatric service institutions. However, no current study has compared the two. Furthermore, gaps exist in our knowledge of both types of stigma. Little is known about the perceived stigma of specific psychiatric service treatment environments, for instance forensic settings. In addition, systematic research on stigma attached to symptoms of personality disorders in the general population is scarce, and for borderline personality disorder, nonexistent...

Reduction in hippocampal volume is a hallmark of schizophrenia and already present in the clinical high-risk state. Nevertheless, other subcortical structures, such as the thalamus, amygdala and pallidum can differentiate schizophrenia patients from controls. We studied the role of hippocampal and subcortical structures in clinical high-risk individuals from two cohorts. High-resolution T1-weighted structural MRI brain scans of a total of 91 clinical high-risk individuals and 64 healthy controls were collected in two centers...

BACKGROUND: There is evidence that exposure to social stress plays a crucial role in the onset and relapse of schizophrenia; however, the reaction of patients with schizophrenia spectrum disorder (SSD) to experimentally induced social stress is not yet fully understood. METHOD: Original research published between January 1993 and August 2015 was included in this systematic literature research. Social stress paradigms, reporting subjective responses to stress measures, plasma or saliva cortisol, or heart rate (HR) in patients with SSD were included...

BACKGROUND: Isolated locoregional recurrences (ILRRs) of breast cancer confer a significant risk for the development of distant metastasis. Management practices and second ILRR events in the Chemotherapy as Adjuvant for LOcally Recurrent breast cancer (CALOR) trial were investigated. METHODS: In this study, 162 patients with ILRR were randomly assigned to receive postoperative chemotherapy or no chemotherapy. Descriptive statistics characterize outcomes according to local therapy and the influence of hormone receptor status on subsequent recurrences...

Autologous transplantation is controversial for older patients with multiple myeloma. The role of age-adjusted high-dose melphalan and the impact of preceeding induction chemotherapy cycles has been unclear. A total of 434 patients 60 to 70 years of age were randomly assigned to 4 cycles of standard anthracycline-based induction chemotherapy or no induction cycles. For all patients, double autologous transplantation after melphalan 140 mg/m2 (MEL140) was planned. The primary end point was progression-free survival...

RATIONALE AND OBJECTIVES: Invasive coronary angiography (ICA) with fractional flow reserve (FFR) assessment is the reference standard for the detection of hemodynamically relevant coronary lesions. We have investigated whether coronary computed tomography angiography (cCTA)-derived FFR (fractional flow reserve from coronary computed tomographic angiography [CT-FFR]) measurement improves diagnostic accuracy over cCTA. METHODS AND RESULTS: A literature search was performed for studies comparing invasive FFR, cCTA, and CT-FFR...

The synthesis of 12 deuterated ceramides with either a deuteration at the last carbon atom of the amide bound fatty acid or a perdeuterated fatty acid chain is described. The ceramides were prepared starting from sphingosine or phytosphingosine and ω deuterated or perdeuterated fatty acids with PyBOP® as activating agent in high yields. For the synthesis of the specifically deuterated fatty acids, dicarboxylic acids were transformed into ω deuterated alkyl bromide, which was chain elongated with blocked ω bromo alcohols by copper catalyzed Grignard coupling...

Time of flight secondary ion mass spectrometry (ToF-SIMS) was used to image the lipid localization in brain tissue sections from rats fed specially processed cereals (SPC). An IonTof 5 instrument equipped with a Bi cluster ion gun was used to analyze the tissue sections. Data from 15 brain samples from control and cereal-fed rats were recorded and exported to principal components analysis (PCA). The data clearly show changes of certain lipids in the brain following cereal feeding. PCA score plots show a good separation in lipid distribution between the control and the SPC-fed group...

Stress increases the risk for major depressive disorder (MDD), overeating, and alcohol dependence (AD). The neuropeptide Y system is one of the best-known modulators of the stress response, and some of its effects are mediated through the neuropeptide Y receptor Y2 (NPY2R). The functional NPY2R variant rs6857715 (C-599T) has been implicated in both obesity and AD, but with opposing alleles. The present study explored whether rs6857715 is also associated with MDD. Analysis of the overall sample (595 MDD cases; 1295 controls) showed an association with the AD risk allele C [P=0...

BACKGROUND: Leiomyosarcoma of vascular smooth muscle is a very rare entity. A fair number of cases of vascular leiomyosarcomas have been reported, and the vast majority of these tumors arose from the inferior vena cava. CASE PRESENTATION: We report the case of a 71-year-old female patient who presented with recurrent upper abdominal pain. A CT-scan demonstrated a heterogenous mass in the liver hilum. Liver function tests and hematology parameters as well as the tumor markers were normal...

PURPOSE: White light cystoscopy (WLC) is the standard procedure for visualising non-muscle invasive bladder cancer (NMIBC). However, WLC can fail to detect all cancerous lesions, and outcomes with transurethral resection of the bladder differ between institutions, controlled trials, and possibly between trials and routine application. This noninterventional study assessed the benefit of hexaminolevulinate blue light cystoscopy (HALC; Hexvix(®), Ipsen Pharma GmbH, Germany) plus WLC versus WLC alone in routine use...

INTRODUCTION: The learning curve in minimally invasive surgery is much longer than in open surgery. This is thought to be due to the higher demands made on the surgeon's skills. Therefore, the question raised at the outset of training in laparoscopic surgery is how such skills can be acquired by undergoing training outside the bounds of clinical activities to try to shorten the learning curve. Simulation-based training courses are one such model. METHODS: In 2011, the surgery societies of Germany adopted the "laparoscopic surgery curriculum" as a recommendation for the learning content of systematic training courses for laparoscopic surgery...

BACKGROUND: Peroxisome proliferator-activated receptors (PPARs) are ligand-activated transcription factors that are implicated in the regulation of lipid and glucose homeostasis. PPAR agonists have been shown to control inflammatory processes, in part by inhibiting the expression of distinct proinflammatory genes such as vascular cell adhesion molecule-1 (VCAM-1), IL-8, and intercellular adhesion molecule-1 (ICAM-1). ICAM-1 is an important endothelial membrane receptor that facilitates the transmigration of leukocytes across the endothelium...

Hypofertility is a risk factor for the development of testicular germ cell tumors (TGCTs), but the initiating event linking these pathologies is unknown. We hypothesized that excessive planar division of undifferentiated germ cells promotes their self-renewal and TGCT development. However, our results obtained from mouse models and seminoma patients demonstrated the opposite. Defective planar divisions of undifferentiated germ cells caused their premature exit from the seminiferous tubule niche, resulting in germ cell depletion, hypofertility, intratubular germ cell neoplasia and seminoma development...
