Abstract
BACKGROUND Accumulating evidence suggests beneficial effects of media stories featuring individuals mastering their suicidal crises, but effects have not been assessed for psychiatric patients. METHODS We randomized n = 172 adult psychiatric patients (n = 172, 97.1% inpatients) to read an educative article featuring a person mastering a suicidal crisis (n = 92) or an unrelated article (n = 80) in a single-blind randomized controlled trial. Questionnaire data were collected before (T1) and after exposure (T2) as well as 1 week later (study end-point, T3). The primary outcome was suicidal ideation as assessed with the Reasons for Living Inventory; secondary outcomes were help-seeking intentions, mood, hopelessness, and stigmatization. Differences between patients with affective versus other diagnoses were explored based on interaction tests. RESULTS We found that patients with affective disorders (n = 99) experienced a small-sized reduction of suicidal ideation at 1-week follow up (mean difference to control group [MD] at T3 = -0.17 [95% CI -0.33, -0.03], d = -0.15), whereas patients with nonaffective diagnoses (n = 73) experienced a small-sized increase (T2: MD = 0.24 [95% CI 0.06, 0.42], d = 0.19). Intervention group participants further experienced a nonsustained increase of help-seeking intentions (T2: MD = 0.53 [95% CI 0.11, 0.95], d = 0.19) and a nonsustained deterioration of mood (T2: MD = -0.14 [95% CI -0.27, -0.02], d = -0.17). CONCLUSIONS This study suggests that patients with affective disorders appear to benefit from media materials featuring mastery of suicidal crises. More research is needed to better understand which patient groups are at possible risk of unintended effects.

Reliability of Plain Radiographs Versus Magnetic Resonance Imaging to Measure Tibial Slope in Sports Medicine Patients: Can They Be Used Interchangeably? Orthop J Sports Med 2021; 9:23259671211033882. [PMID: 34646895 PMCID: PMC8504693 DOI: 10.1177/23259671211033882] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [What about the content of this article?

Abstract
Background: The slope of the tibial plateau has been proposed as a reason for failure of anterior cruciate ligament reconstruction. Purpose: To evaluate the interobserver reliability of measurements of tibial slope on radiographs versus magnetic resonance imaging (MRI) scans and to assess whether the modalities can be used interchangeably for this purpose. Study Design: Cohort study (diagnosis); Level of evidence, 3. Methods: This retrospective study included 81 patients aged 18 to 30 years who were evaluated in a sports medicine setting for knee pain and who had lateral knee radiographs as well as knee MRI scans on file. Medial and lateral tibial plateau slope measurements were made by 3 blinded reviewers from the radiographs and MRI scans using graphic overlay software. The paired t test was used to compare measurements of the medial tibial plateau slope (MTPS) and lateral tibial plateau slope (LTPS) from radiographs and MRI scans. Intraclass correlation coefficients (ICCs) were calculated to determine intra- and interobserver reliability of measurements within each imaging modality, and Pearson correlation coefficients were calculated to determine the relationship between measurements on radiographs versus MRI scans. Results: Imaging from 81 patients were included. The average MTPS was significantly larger on radiographs compared with MRI scans (8.7° ± 3.6° vs 3.7° ± 3.4°; P < .001), and the average LTPS was also significantly larger on radiographs compared with MRI scans (7.9° ± 3.4° vs 5.7° ± 3.7°; P < .001). ICC values indicated good to excellent intraobserver agreement for all imaging modalities (ICC, 0.81-0.97; P ≤ .009). The ICCs for interobserver reliability of MTPS and LTPS measurements were 0.92 and 0.85 for radiographs, 0.87 and 0.83 for MRI based off the subchondral bone, and 0.86 and 0.71 for MRI based off the cartilage, respectively (P < .001). Medium correlation was noted between radiographic and MRI measurements; Pearson correlation coefficients for radiographic versus subchondral MRI measurements were 0.30 and 0.37 for MTPS and LTPS, respectively. Conclusion: The average MTPS and LTPS were significantly larger on radiographs compared with MRI scans. Although tibial slope measurements using radiography and those using MRI are reliable between individuals, the measurements from radiographs and MRI scans cannot be used interchangeably, and caution should be used when interpreting and comparing studies using measurements of the tibial slope.

Abstract
Abstract
This presentation discusses the findings of a Health Evidence Network synthesis report on availability and integration of refugee and migrant health data in health information systems in the WHO European Region. Based on an analysis of 41 full-text studies and 696 abstracts, the report found that refugee and migrant health data were available in less than half of the Region's Member States, and that data availability and integration, data collection systems, as well as indicators on migration varied markedly between states. From these findings, the report derived key policy considerations regarding the strengthening and harmonization of migrant health data collection, as well as governance and monitoring of health information systems.

Abstract
Abstract
Background
International migration leads to an increasingly fluctuating and superdiverse migrant population in reception countries. In Germany, structural, legal, social and political barriers to adequate care complicate the ability of health care professionals to respond to the challenges associated with caring for such a dynamic patient population. In this analysis, we explore the views of physicians working with asylum seekers and refugees in Germany, and aim to identify the barriers and enablers they face in providing appropriate care.
Methods
We performed a secondary qualitative analysis of 16 semi-structured interviews conducted for two studies on the delivery of medical care to asylum seekers in Germany. To examine physicians' views towards their work with asylum seekers, we analysed evaluative judgements on interpersonal and workplace factors, the external environment, the physician's own self, and individual medical conduct. Analysis was conducted by identifying cross-cutting themes through thematic analysis and mapping these onto a framework matrix.
Results
We found that evaluative judgements made by physicians providing care to asylum seekers emphasized one of three conceptualisations of “difference”: regarding personal or cultural attributes of the patient group; the spaces of care provision; or the context of asylum seeking patients. Emphasis on differences of the patient population and the spaces of care provision to asylum seekers was found to impede appropriate care, while physicians emphasizing contextual factors reported more responsive medical practices.
Discussion
Our findings suggest that processes of “othering” asylum seekers as a patient group as well as the heterotopic spaces of care provision endanger the doctor-patient relationship and responsiveness of care. Appropriate training, physical and human resources and encouraging support between physicians working with asylum seeking patients could alleviate these processes.
Key messages
Physicians’ conceptualisations of “difference” in providing care to asylum seekers focus on the patient group, workplace, or structural context; and affect the way in which medical care is provided. Structural competency training, resource investments, and clear structures could reduce physicians’ experiences of “difference” of the patient group and workplace, and facilitate responsive care.

Abstract
Abstract
Background
Providing high-quality health care to superdiverse populations of newly arrived refugees poses specific structural, organisational, communicative, ethical and medical challenges that medical students in Europe are often not systematically prepared for. We created a clinical elective, to enable future doctors to identify and address the needs of refugee-patients and deliver high quality care to this population.
Objectives
We provided medical, structural, administrative, communicative and socio-cultural knowledge and skills training through seminars (24 h) and field placements (2 days) in a reception centre clinic for refugees. The training aimed at stimulating a systematic professional, personal, scientific, and political reflection, to foster social accountability, and raise awareness for the special situation of vulnerable groups. The didactic concept built on multidisciplinary lectures, student centred teaching, and research-oriented learning. Mainly qualitative summative and formative evaluations were applied to improve the course and examine training outcomes.
Results
A total of 112 students completed the elective over four terms, 50 evaluated it, of which 80% considered it worthwhile. Self-reported competencies in caring for refugee patients were low at the beginning and increased after course completion. The most important learning outcomes were knowledge of the asylum-law, gaining a multi-perspective view through multiple disciplinary lenses as well as professional, ethical, interpersonal and political insights during practical experience and reflection.
Conclusions
A multidisciplinary course that combines theory, practice and reflection, can prepare students for the complex challenges medical professionals face in caring for refugees. This could help strengthen their professional role as advocates of health equity. Our innovative didactical approach, course and evaluation concept can inspire the creation and implementation of similar courses elsewhere.
Key messages
The health workforce needs training to identify, address and help compensate respective barriers to health care and foster equal opportunities to health for refugees. A multidisciplinary teaching concept, tailored to specific target groups can help make future doctors and nurses in Europe fit for their responsibility and work in plural and ever changing societies.

Abstract
Abstract
Background
Health monitoring in Germany falls short on generating timely, reliable and representative data among migrants, especially transient groups such as asylum seekers and refugees (ASR). We aim to advance health monitoring approaches and obtain reliable estimates on health status and access to health services among ASR in Germany’s 3rd largest federal state.
Methods
We conducted a state-wide, cross-sectional, population-based health monitoring survey in nine languages among ASR in collective accommodation centres. Questionnaire items capturing health status, access to care and sociodemographic variables were taken from established surveys and translated using a team approach. Random sampling on the level of 1,938 accommodation centres was employed to draw a balanced sample. Multilingual field teams recruited eligible participants using a “door-to-door” approach.
Results
Fieldwork was conducted in 58 centres, obtaining a response rate of 42.2% (n = 412). Age, sex and nationality of the included sample were comparable to the population of asylum applicants in Germany. Adults reported longstanding limitations (16%), bad/very bad general health (19%), pain (25%), chronic illness (40%), and depressive (46%) and anxiety symptoms (45%). 52% utilised primary and 37% specialist care services in the previous 12 months, while reporting unmet needs for primary (31%) and specialist care (32%). Younger and male participants had above-average health status and below-average utilisation, in contrast to older and female ASR.
Conclusions
Our health monitoring survey yielded reliable estimates on health status and health care access among ASR, revealing relevant morbidities and patterns of care. Applying rigorous epidemiological methods in linguistically diverse, transient and marginalized populations is challenging, but feasible. Integration of this approach into state- and nation-wide health monitoring strategies is needed to sustain this approach as a health planning tool.
Key messages
Applying rigorous epidemiological methods in linguistically diverse, transient and marginalized populations is challenging, but feasible. Sustainable integration of multi-lingual epidemiological methods is required in state- and nation-wide health monitoring to capture health status and access to health services for ASR.

Abstract
Abstract
Background
Reliable data on health and primary care among asylum seekers in reception centers are essential for the planning and provision of medical services, but haphazard care provision and lack of standards for health information systems in these centers preclude routine health monitoring. We aimed to establish a routine surveillance system in reception centers for asylum seekers in Germany, generating multi-center data on key health indicators.
Methods
To enable routine health surveillance, we established an electronic medical records system (RefCare©), a research network, and an IT-infrastructure for the automated analysis of health data in German reception centers. Within the network, 64 health and health care indicators on morbidity, care processes, quality of care and syndromic surveillance were identified. In November 2018, we analyzed 33 indicators using routine health data from nine centers in three federal states. We calculated single-center prevalence and pooled estimates for selected morbidity indicators stratified by age and sex, and process and quality indicators stratified by center.
Results
A total of 8,406 patients and 39,449 patient contacts were analyzed, with mean utilization of health services ranging from 2.33 (Standard deviation, SD: 2.0) to 11.49 (SD: 22.82). The morbidities with the highest prevalence were respiratory, digestive and certain infectious diseases, followed by consequences of external causes, musculoskeletal and mental health conditions. Irrational use of antibiotics was below the threshold for primary care settings.
Conclusions
For the first time in Germany, a harmonized infrastructure for the automated, anonymized surveillance of the health and health care of asylum seekers in reception centers was established in several federal states. The analysis of morbidity indicators shows a primary care-typical disease profile, with special needs regarding mental health and consequences of external causes, such as physical trauma.
Key messages
Routine health surveillance of asylum seekers in reception centers can be achieved through an innovative harmonized, cross-regional, multi-center, anonymous and automated surveillance system. Health issues of asylum seekers in reception centers in Germany mainly consist of primary care conditions with special vulnerabilities regarding mental health and consequences of external causes.

Abstract
AIMS The way an individual handles the experience of psychosis, the so-called 'recovery style', has been shown to substantially affect long-term outcomes. The Recovery Style Questionnaire (RSQ) measures this psychological dimension. The aim of this study was to provide a validation of the German version of the RSQ and to raise awareness for recovery-oriented approaches. METHODS The RSQ was translated into German according to the guidelines of the WHO and patients were administered this questionnaire and measures of internalised stigma, psychotic symptoms, illness concept, empowerment, self-esteem and quality of life. Descriptive statistics were demonstrated to characterise the sample. Reliability was assessed in different forms: internal consistency, test-retest reliability and split-half reliability. Items were evaluated with descriptive data and item-total correlations. Convergent and discriminant validity were shown, and a confirmatory factor analysis was performed. In order to ameliorate the model, a post hoc model modification was done. RESULTS The sample consisted of 138 patients diagnosed with schizophrenia spectrum disorders (mean age: 35.7 years; 53.6% men; mean duration of illness: 20.6 years) with a mean RSQ overall percentage of 66.12 (s.d. ± 17.43%), mainly representing the categories 'mixed picture' and 'tends towards integration'. The reliability of the RSQ was acceptable with a Cronbach's α of 0.741 and a test-retest coefficient of 0.502. Item-total correlations were not acceptable for 27 of 39 items. Moderate evidence for convergent validity of the RSQ was found. Confirmatory factor analysis revealed that the 13-factor model with 39 items originally proposed was partially poorly replicated in the present sample (χ2 ratio to degrees of freedom (χ2/df) of 1.732, Comparative Fit Index (CFI) of 0.585, Normed Fit Index (NFI) of 0.414, Tucker-Lewis Index (TLI) of 0.508, root mean square error of approximation (RMSEA) of 0.095). The RSQ was modified based on item-total correlations and path coefficients of the single items. The confirmatory factor analysis of the resulting one-factor model with 11 items showed adequate fit to the data (χ2/df of 1.562, CFI of 0.936, NFI of 0.847, TLI of 0.910, RMSEA of 0.083) and demonstrated good model fit. CONCLUSIONS Despite partially insufficient psychometric data of the original RSQ, the concept of recovery style is beneficial to psychiatric research and clinical practice. The underlying idea is valuable, and the questionnaire needs further development. Therefore, a short version of the RSQ is proposed.

Abstract
The COMPASS Collaboration at CERN has measured diffractive dissociation of 190 GeV/c pions into the π(-)π(-)π(+) final state using a stationary hydrogen target. A partial-wave analysis (PWA) was performed in bins of 3π mass and four-momentum transfer using the isobar model and the so far largest PWA model consisting of 88 waves. A narrow peak is observed in the f0(980)π channel with spin, parity and C-parity quantum numbers J(PC)=1(++). We present a resonance-model study of a subset of the spin-density matrix selecting 3π states with J(PC)=2(++) and 4(++) decaying into ρ(770)π and with J(PC)=1(++) decaying into f0(980)π. We identify a new a1 meson with mass (1414(-13)(+15)) MeV/c2 and width (153(-23)(+8)) MeV/c2. Within the final states investigated in our analysis, we observe the new a1(1420) decaying only into f0(980)π, suggesting its exotic nature.

Abstract
Concept and design of an independent scientific evaluation of different pathways of care for schizophrenia patients in Germany with respect to effectiveness and efficiency are presented. In this prospective, observational study, schizophrenia patients receiving an integrated care treatment, the intervention group (IG), are compared with patients under routine care conditions treated by the same physician (first control group, CG 1). A second control group (CG 2) of patients treated by office-based psychiatrists not participating in the integrated care program will be recruited and their data compared with the two other groups. The total amount of psychiatric hospital days after 12 months is defined as primary outcome parameter. Secondary outcome parameters comprise the frequency of psychiatric inpatient readmissions, severity of schizophrenia symptoms, remission rates and quality of life. Patients undergo assessments at baseline, month 6 and 12 using standardized and experimental questionnaires. Routine data of a regional German social health insurance fund complement information on included patients. Additionally, a cost-effectiveness and cost-utility analysis will be performed. Until now, 137 psychiatrists included 980 patients in the integrated care project in Lower Saxony, Germany, and 47 psychiatrists (IG and both CGs) are willing to participate in the independent evaluation. For the first time, a prospective observational controlled evaluation study of a countrywide integrated care project planning to recruit 500 schizophrenia patients has started using comprehensive assessments as well as routine data of a social health insurance fund.

Abstract
The COMPASS collaboration at CERN has investigated pion Compton scattering, π(-)γ→π(-)γ, at center-of-mass energy below 3.5 pion masses. The process is embedded in the reaction π(-)Ni→π(-)γNi, which is initiated by 190 GeV pions impinging on a nickel target. The exchange of quasireal photons is selected by isolating the sharp Coulomb peak observed at smallest momentum transfers, Q(2)<0.0015 (GeV/c)(2). From a sample of 63,000 events, the pion electric polarizability is determined to be α(π)=(2.0±0.6(stat)±0.7(syst))×10(-4) fm(3) under the assumption α(π)=-β(π), which relates the electric and magnetic dipole polarizabilities. It is the most precise measurement of this fundamental low-energy parameter of strong interaction that has been addressed since long by various methods with conflicting outcomes. While this result is in tension with previous dedicated measurements, it is found in agreement with the expectation from chiral perturbation theory. An additional measurement replacing pions by muons, for which the cross-section behavior is unambiguously known, was performed for an independent estimate of the systematic uncertainty.

Abstract
CASE We present two cases of anterior glenohumeral instability in which both the humeral head and the glenoid were reconstructed concurrently with use of allografts; we discuss the midterm outcomes at four and one-half and five years of follow-up, respectively. CONCLUSION In our experience, concomitant glenoid and humeral head allograft reconstruction for anterior glenohumeral instability with severe combined humeral head and glenoid pathology yielded good midterm clinical, functional, and radiographic outcomes. This treatment approach may be a viable option for young and active patients presenting with severe combined glenoid and humeral pathology and warrants additional investigation.

Abstract
Background: Up to 1 billion people have insufficient or deficient vitamin D levels. Despite the well-documented, widespread prevalence of low vitamin D levels and the importance of vitamin D for athletes, there is a paucity of research investigating the prevalence of vitamin D deficiency in athletes. Hypothesis: We investigated the prevalence of abnormal vitamin D levels in National Collegiate Athletic Association (NCAA) Division I college athletes at a single institution. We hypothesized that vitamin D insufficiency is prevalent among our cohort. Study Design: Cohort study. Level of Evidence: Level 1. Methods: We measured serum 25-hydroxyvitamin D (25(OH)D) levels of 223 NCAA Division I athletes between June 2012 and August 2012. The prevalence of normal (≥32 ng/mL), insufficient (20 to <32 ng/mL), and deficient (<20 ng/mL) vitamin D levels was determined. Logistic regression was utilized to analyze risk factors for abnormal vitamin D levels. Results: The mean serum 25(OH)D level for the 223 members of this study was 40.1 ± 14.9 ng/mL. Overall, 148 (66.4%) participants had sufficient 25(OH)D levels, and 75 (33.6%) had abnormal levels. Univariate analysis revealed the following significant predictors of abnormal vitamin D levels: male sex (odds ratio [OR] = 2.83; P = 0.0006), Hispanic race (OR = 6.07; P = 0.0063), black race (OR = 19.1; P < 0.0001), and dark skin tone (OR = 15.2; P < 0.0001). Only dark skin tone remained a significant predictor of abnormal vitamin D levels after multivariate analysis (adjusted OR = 15.2; P < 0.0001). Conclusion: In a large cohort of NCAA athletes, more than one third had abnormal vitamin D levels. Races with dark skin tones are at much higher risk than white athletes. Male athletes are more likely than female athletes to be vitamin D deficient. Our study demonstrates a high prevalence of vitamin D deficiency among healthy NCAA athletes. Clinical Relevance: Many studies indicate a significant prevalence of vitamin-D insufficiency across various populations. Recent studies have demonstrated a direct relationship between serum 25(OH)D levels and muscle power, force, velocity, and optimal bone mass. In fact, studies examining muscle biopsies from patients with low vitamin D levels have demonstrated atrophic changes in type II muscle fibers, which are crucial to most athletes. Furthermore, insufficient 25(OH)D levels can result in secondary hyperparathyroidism, increased bone turnover, bone loss, and increased risk of low trauma fractures and muscle injuries. Despite this well-documented relationship between vitamin D and athletic performance, the prevalence of vitamin D deficiency in NCAA athletes has not been well studied.

Abstract
BACKGROUND Although operative treatment may offer an appropriate management option for displaced glenoid fractures, there is sparse research assessing post-operative functional outcomes. This study assessed functional outcomes of patients after undergoing open reduction and internal fixation of displaced glenoid fractures. METHODS Fifteen patients were treated with open reduction and internal fixation for displaced intra-articular fractures between 2005 and 2010. The indication for operative fixation was intra-articular displacement >4 mm. Post-operative functional outcomes were assessed via retrospective chart review. Evaluation included review of pre-operative imaging for fracture type, review of post-operative plain radiographs for fracture healing, Disabilities of the Arm Shoulder and Hand (DASH) and American Shoulder and Elbow Surgeon Assessment (ASES) scores at last follow-up. RESULTS At a mean follow-up of 49 months (24-87 months) all patients had radiographic healing. The mean DASH score was 10 (range 0.83-29.17). Mean ASES score was 90 (range 41.7-100). No patients had evidence of hardware failure or infection. CONCLUSIONS Open reduction and internal fixation of displaced intra-articular glenoid fractures results in stable fixation and is associated with good functional outcome. LEVEL OF EVIDENCE Level IV.

Abstract
The COMPASS Collaboration at CERN has investigated the π- γ → π- π- π+ reaction at center-of-momentum energy below five pion masses, sqrt[s]<5m(π), embedded in the Primakoff reaction of 190 GeV pions impinging on a lead target. Exchange of quasireal photons is selected by isolating the sharp Coulomb peak observed at smallest momentum transfers, t'<0.001 GeV2/c2. Using partial-wave analysis techniques, the scattering intensity of Coulomb production described in terms of chiral dynamics and its dependence on the 3π-invariant mass m(3π)=sqrt[s] were extracted. The absolute cross section was determined in seven bins of sqrt[s] with an overall precision of 20%. At leading order, the result is found to be in good agreement with the prediction of chiral perturbation theory over the whole energy range investigated.

Abstract
Numerous health systems have introduced competition between health plans while banning risk-rated premiums. Risk adjustment for health plans is introduced to reduce incentives for risk selection and to create incentives for health plans to permanently invest in care for the chronically ill. According to the international health economics state of the art, risk adjustment in the German social health insurance system has used information on health status (measured by diagnoses and drug prescriptions) on top of demographic information since 2009. In non-competitive health care systems similar mechanisms are sometimes established, e.g. to achieve an equitable distribution of resources between regions. An evaluation of the first year of health-based risk adjustment demonstrates a superior performance in comparison to the old, demographic risk adjustment. The old risk adjustment formula (without ex post high-cost pooling) showed R(2) of 5.8%, CPM of 10.4% and MAPE of 2,226 €, in contrast to the new health status-based risk adjustment formula (without cash benefit for sick allowance) which reaches R(2) 20.2%, CPM 22.5% and MAPE 1,817 €. However, to make competition between health plans functional for improvement of quality and efficiency of health care, health plans must be granted additional instruments to act as prudent buyers of health care.

Abstract
The size polydispersity distribution of synaptic vesicles (SVs) is characterized under quasi-physiological conditions by dynamic light scattering (DLS). Highly purified fractions of SVs obtained from rat brain still contain a small amount of larger contaminant structures, which can be quantified by DLS and further reduced by asymmetric-flow field-flow (AFFF) fractionation. The intensity autocorrelation functions g (2)(τ) recorded from these samples are analyzed by a constrained regularization method as well as by an alternative direct modeling approach. The results are in quantitative agreement with the polydispersity obtained from cryogenic electron microscopy of vitrified SVs. Next, different vesicle fusion assays based on samples composed of SVs and small unilamellar proteoliposomes with the fusion proteins syntaxin 1 and SNAP-25A are characterized by DLS. The size increase of the proteoliposomes due to SNARE-dependent fusion with SVs is quantified by DLS under quasi-physiological conditions.

Abstract
The COMPASS experiment at the CERN SPS has studied the diffractive dissociation of negative pions into the π- π- π+ final state using a 190 GeV/c pion beam hitting a lead target. A partial wave analysis has been performed on a sample of 420,000 events taken at values of the squared 4-momentum transfer t' between 0.1 and 1 GeV2/c2. The well-known resonances a1(1260), a2(1320), and π2(1670) are clearly observed. In addition, the data show a significant natural-parity exchange production of a resonance with spin-exotic quantum numbers J(PC)=1-+ at 1.66 GeV/c2 decaying to ρπ. The resonant nature of this wave is evident from the mass-dependent phase differences to the J(PC)=2-+ and 1++ waves. From a mass-dependent fit a resonance mass of (1660±10(-64)(+0)) MeV/c2 and a width of (269±21(-64)(+42)) MeV/c2 are deduced, with an intensity of (1.7±0.2)% of the total intensity.

Abstract
First measurements of the Collins and Sivers asymmetries of charged hadrons produced in deep-inelastic scattering of muons on a transversely polarized 6LiD target are presented. The data were taken in 2002 with the COMPASS spectrometer using the muon beam of the CERN SPS at 160 GeV/c. The Collins asymmetry turns out to be compatible with zero, as does the measured Sivers asymmetry within the present statistical errors.

Abstract
CASE The case of a primary multicentric cutaneous epithelioid angiosarcoma is described. A 39-year-old female patient presented with a tumor on the left distal forearm and the fourth finger of the left hand. Partial amputation of the left hand and local excision of the tumor on the left forearm were performed. For the next three years the patient was free of local or systemic recurrence. After this time period, a left shoulder exarticulation had to be performed because of tumor recurrence in the left axilla. The patient died 64 months after diagnosis. CONCLUSION Cutaneous epithelioid angiosarcoma is a highly malignant tumor which has only been described once on the hand. The treatment primarily is a surgical one. If possible, the function of the extremity should be preserved as long as possible.

Abstract
Quantal neurotransmitter release at excitatory synapses depends on glutamate import into synaptic vesicles by vesicular glutamate transporters (VGLUTs). Of the three known transporters, VGLUT1 and VGLUT2 are expressed prominently in the adult brain, but during the first two weeks of postnatal development, VGLUT2 expression predominates. Targeted deletion of VGLUT1 in mice causes lethality in the third postnatal week. Glutamatergic neurotransmission is drastically reduced in neurons from VGLUT1-deficient mice, with a specific reduction in quantal size. The remaining activity correlates with the expression of VGLUT2. This reduction in glutamatergic neurotransmission can be rescued and enhanced with overexpression of VGLUT1. These results show that the expression level of VGLUTs determines the amount of glutamate that is loaded into vesicles and released and thereby regulates the efficacy of neurotransmission.

Abstract
Protein conformational transitions form the molecular basis of many cellular processes, such as signal transduction and membrane traffic. However, in many cases, little is known about their structural dynamics. Here we have used dynamic single-molecule fluorescence to study at high time resolution, conformational transitions of syntaxin 1, a soluble N-ethylmaleimide-sensitive factor attachment protein receptors protein essential for exocytotic membrane fusion. Sets of syntaxin double mutants were randomly labeled with a mix of donor and acceptor dye and their fluorescence resonance energy transfer was measured. For each set, all fluorescence information was recorded simultaneously with high time resolution, providing detailed information on distances and dynamics that were used to create structural models. We found that free syntaxin switches between an inactive closed and an active open configuration with a relaxation time of 0.8 ms, explaining why regulatory proteins are needed to arrest the protein in one conformational state.

Abstract
In humans, mutations in the alpha-synuclein gene or exposure to the neurotoxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) produce Parkinson's disease with loss of dopaminergic neurons and depletion of nigrostriatal dopamine. alpha-Synuclein is a vertebrate-specific component of presynaptic nerve terminals that may function in modulating synaptic transmission. To test whether MPTP toxicity involves alpha-synuclein, we generated alpha-synuclein-deficient mice by homologous recombination, and analyzed the effect of deleting alpha-synuclein on MPTP toxicity using these knockout mice. In addition, we examined commercially available mice that contain a spontaneous loss of the alpha-synuclein gene. As described previously, deletion of alpha-synuclein had no significant effects on brain structure or composition. In particular, the levels of synaptic proteins were not altered, and the concentrations of dopamine, dopamine metabolites, and dopaminergic proteins were unchanged. Upon acute MPTP challenge, alpha-synuclein knockout mice were partly protected from chronic depletion of nigrostriatal dopamine when compared with littermates of the same genetic background, whereas mice carrying the spontaneous deletion of the alpha-synuclein gene exhibited no protection. Furthermore, alpha-synuclein knockout mice but not the mice with the alpha-synuclein gene deletion were slightly more sensitive to methamphetamine than littermate control mice. These results demonstrate that alpha-synuclein is not obligatorily coupled to MPTP sensitivity, but can influence MPTP toxicity on some genetic backgrounds, and illustrate the need for extensive controls in studies aimed at describing the effects of mouse knockouts on MPTP sensitivity.

Abstract
Glutamate is the major excitatory neurotransmitter in mammalian CNS. In the presynaptic nerve terminal, glutamate is stored in synaptic vesicles and released by exocytosis. Previously, it has been shown that a transport protein originally identified as a brain-specific Na(+)-dependent inorganic phosphate transporter I (BNPI) functions as vesicular glutamate transporter and thus has been renamed VGLUT1. Recently, a protein highly homologous to VGLUT1, "differentiation-associated BNPI" (DNPI), has been discovered. Northern blot and in situ hybridization analyses indicate that DNPI mRNA is expressed in some brain regions in which VGLUT1 mRNA is not expressed. We now show that DNPI functions as vesicular glutamate transporter with properties very similar to VGLUT1 and propose to rename the protein VGLUT2. VGLUT2 is highly enriched in synaptic vesicles. Furthermore, VGLUT2 resides on a vesicle population that is distinct from vesicles containing the vesicular GABA transporter or VGLUT1, showing that the expression of VGLUT1 and VGLUT2 do not overlap. When VGLUT2 was expressed in BON cells, membrane fractions displayed ATP-dependent, carbonyl cyanide p-trifluoromethoxyphenylhydrazone-sensitive glutamate uptake. Overexpression of VGLUT2 in cultured autaptic GABAergic neurons yielded postsynaptic currents that were insensitive to the GABA(A) receptor antagonist bicuculline but blocked by the AMPA-receptor antagonist 2,3-dihydroxy-6-nitro-7-sulfonyl-benzo[F]quinoxaline. Thus, expression of VGLUT2 suffices to cause GABAergic neurons to release glutamate in addition to GABA in a manner very similar to that reported previously for VGLUT1.

Abstract
SNARE (soluble NSF acceptor protein receptor) proteins are thought to mediate membrane fusion by assembling into heterooligomeric complexes that connect the fusing membranes and initiate the fusion reaction. Here we used site-directed spin labeling to map conformational changes that occur upon homo- and heterooligomeric complex formation of neuronal SNARE proteins. We found that the soluble domains of synaptobrevin, SNAP-25, and syntaxin 1 are unstructured. At higher concentrations, the SNARE motif of syntaxin 1 forms homooligomeric helical bundles with at least some of the alpha-helices aligned in parallel. In the assembled SNARE complex, mapping of thirty side chain positions yielded spectra which are in good agreement with the recently published crystal structure. The loop region of SNAP-25 that connects the two SNARE motifs is largely unstructured. C-terminal truncation of synaptobrevin resulted in complexes that are completely folded N-terminal of the truncation but become unstructured at the C-terminal end. The binary complex of syntaxin and SNAP-25 consists of a parallel four helix-bundle with properties resembling that of the ternary complex.
