Objectives The four-tied peritoneal regression grading score (PRGS) is increasingly used to evaluate the response of peritoneal metastases (PM) to chemotherapy. The minimal number of peritoneal biopsies needed for PRGS determination remains unclear. Methods A prospective cohort of 89 PM patients treated with 210 pressurized intraperitoneal aerosol chemotherapy (PIPAC) cycles was investigated. Four biopsies from every abdominal quadrant were recommended. Histological tumor response was defined as a stable or decreasing mean PRGS between therapy cycles, progression increasing. We compared the diagnostic uncertainty induced by missing biopsies to the histological response. Results A total of 49 patients had at least two PIPAC and were eligible for therapy response assessment. Mean PRGS decreased from 2.04 (CI 5–95% 1.85–2.27) to 1.79 (CI 5–95% 1.59–2.01), p=0.14, as a proof of therapy effectiveness. 35 (71.4%) patients had a stable or decreasing PRGS (therapy response), 14 (28.6%) a PRGS increase (disease progression). Histology showed agreement between four biopsies in 42/210 laparoscopies (20%), between ≥3 biopsies in 103 (49%), and between ≥2 biopsies in 169 laparoscopies (81%). Mean loss of information with one missing biopsy was 0.11 (95% CI=0.13) PRGS points, with two missing biopsies 0.18 (95% CI 0.21). In 9/49 patients (18.3%), the loss of information with one less biopsy exceeded the change in PRGS under therapy. Conclusions A minimum of three biopsies is needed to diagnose PM progression with an accuracy superior to 80%. Missing biopsies often result in a false diagnosis of tumor progression.

Zusammenfassung Hintergrund Die Leberchirurgie ist durch ein hohes perioperatives Risiko und einen großen Ressourcenaufwand geprägt, aber die Operationsindikation ist oftmals alternativlos. Die SARS-CoV-2-Pandemie führte weltweit zu Einschränkungen in der chirurgischen Patientenversorgung und stellte daher auch die Leberchirurgie vor neue Herausforderungen. Welchen Einfluss die Pandemie allerdings auf die Leberchirurgie in Deutschland insgesamt hatte, ist bislang nur unzureichend bekannt. Methoden Auf Basis der durch das Statistische Bundesamt (Destatis) erfassten Daten zu Prozedurenschlüsseln (OPS-Codes) vollstationärer Patienten in Deutschland aus den Jahren 2010–2020 sowie Daten zu Organtransplantationen der Deutschen Stiftung Organtransplantation (DSO) wurde retrospektiv die Anzahl leberchirurgischer Prozeduren in Deutschland zu Beginn der Pandemie mit den Vorjahresdaten sowie mit Zahlen aus dem Eurotransplant-Raum verglichen. Ergebnisse Entsprechend der durch das Statistische Bundesamt dokumentierten Prozedurenschlüssel unterlagen Operationen an der Leber sowie Lebertransplantationen in Deutschland in den Jahren 2010 bis 2020 einer jährlichen Schwankung, die auch im Pandemiejahr 2020, im Gegensatz zu anderen europäischen Ländern, unverändert geblieben ist. Die Entwicklung der postmortalen Lebertransplantation sowie der Leberlebendspenden ist in Deutschland, gemäß den Zahlen der DSO, auch im Jahr 2020 stabil geblieben. Schlussfolgerungen Die Anzahl leberchirurgischer Eingriffe in Deutschland unterlag bis 2020 einer dynamischen Entwicklung, die auch im 1. Pandemiejahr 2020 keine deutliche Veränderung gezeigt hat. Die häufigsten an der Leber durchgeführten Operationen sowie die Lebertransplantation entwickelten sich auch zu Beginn der Pandemie quantitativ weitgehend stabil. Die Veröffentlichung von Daten zu den entsprechenden Prozedurenschlüsseln für das Jahr 2021 bleibt abzuwarten, um die weitere Entwicklung der Leberchirurgie und -transplantation in Deutschland während der SARS-CoV-2-Pandemie beurteilen zu können.

Background Systemic glucocorticosteroids (“steroids”) are widely used worldwide as a standard of care for primary therapy of idiopathic sudden sensorineural hearing loss (ISSHL). The German ISSHL guideline recommends high-dose steroids without evidence from randomized controlled trials (RCTs) and refers solely to retrospective cohort studies. This RCT aims to assess the efficacy (improvement in hearing) and safety (especially systemic side effects) of high-dose steroids versus standard of care (standard dose systemic steroids) for the treatment of unilateral ISSHL, when given as a primary therapy. Methods The study is designed as a multicenter (approximately 40 centers), randomized, triple-blind, three-armed, parallel group, clinical trial with 312 adult patients. The interventions consist of 5 days of 250 mg/day intravenous prednisolone (intervention 1) + oral placebo, or 5 days of 40 mg/day oral dexamethasone (intervention 2) + intravenous placebo. The control intervention consists of 60 mg oral prednisolone for 5 days followed by five tapering doses + intravenous placebo. The primary efficacy endpoint is the change in hearing threshold in the three most affected contiguous frequencies between 0.25 and 8 kHz 1 month after ISSHL. Secondary endpoints include further measures of hearing improvement including speech audiometry, tinnitus, quality of life, blood pressure, and altered glucose tolerance. Discussion There is an unmet medical need for an effective medical therapy of ISSHL. Although sensorineural hearing impairment can be partially compensated by hearing aids or cochlear implants (CI), generic hearing is better than using hearing aids or CIs. Since adverse effects of a short course of high-dose systemic corticosteroids have not been documented with good evidence, the trial will improve knowledge on possible side effects in the different treatment arms with a focus on hyperglycemia and hypertension.

Contains fulltext : 290914.pdf (Publisher’s version ) (Open Access) BACKGROUND: In node-negative breast cancer (NNBC), a high risk of recurrence is determined by clinico-pathological or tumor-biological assessment. Taxanes may improve adjuvant chemotherapy. METHODS: NNBC 3-Europe, the first randomized phase-3 trial in node-negative breast cancer (BC) with tumor-biological risk assessment, recruited 4146 node-negative breast cancer patients from 2002 to 2009 in 153 centers. Risk assessment was performed by clinico-pathological factors (43%) or biomarkers (uPA/PAI-1, urokinase-type plasminogen activator/its inhibitor PAI-1). High-risk patients received six courses 5-fluorouracil (500 mg/m(2)), epirubicin (100 mg/m(2)), cyclophosphamide (500 mg/m(2)) (FEC), or three courses FEC followed by three courses docetaxel 100 mg/m(2) (FEC-Doc). Primary endpoint was disease-free survival (DFS). RESULTS: In the intent-to-treat population, 1286 patients had received FEC-Doc, and 1255 received FEC. Median follow-up was 45 months. Tumor characteristics were equally distributed; 90.6% of tested tumors had high uPA/PAI-1-concentrations. Planned courses were given in 84.4% (FEC-Doc) and 91.5% (FEC). Five-year-DFS was 93.2% (95% C.I. 91.1-94.8) with FEC-Doc and 93.7% (91.7-95.3) with FEC. Five-year-overall survival was 97.0% (95.4-98.0) for FEC-Doc and 96.6% % (94.9-97.8) for FEC. CONCLUSIONS: With adequate adjuvant chemotherapy, even high-risk node-negative breast cancer patients have an excellent prognosis. Docetaxel did not further reduce the rate of early recurrences and led to significantly more treatment discontinuations.

T cell immunity is central for the control of viral infections. CoVac-1 is a peptide-based vaccine candidate, composed of SARS-CoV-2 T cell epitopes derived from various viral proteins1,2, combined with the Toll-like receptor 1/2 agonist XS15 emulsified in Montanide ISA51 VG, aiming to induce profound SARS-CoV-2 T cell immunity to combat COVID-19. Here we conducted a phase I open-label trial, recruiting 36 participants aged 18–80 years, who received a single subcutaneous CoVac-1 vaccination. The primary end point was safety analysed until day 56. Immunogenicity in terms of CoVac-1-induced T cell response was analysed as the main secondary end point until day 28 and in the follow-up until month 3. No serious adverse events and no grade 4 adverse events were observed. Expected local granuloma formation was observed in all study participants, whereas systemic reactogenicity was absent or mild. SARS-CoV-2-specific T cell responses targeting multiple vaccine peptides were induced in all study participants, mediated by multifunctional T helper 1 CD4+ and CD8+ T cells. CoVac-1-induced IFNγ T cell responses persisted in the follow-up analyses and surpassed those detected after SARS-CoV-2 infection as well as after vaccination with approved vaccines. Furthermore, vaccine-induced T cell responses were unaffected by current SARS-CoV-2 variants of concern. Together, CoVac-1 showed a favourable safety profile and induced broad, potent and variant of concern-independent T cell responses, supporting the presently ongoing evaluation in a phase II trial for patients with B cell or antibody deficiency., A phase I open-label trial evaluating the immunogencity, reactogenicity and safety of a peptide-based SARS-CoV-2 vaccine candidate to induce SARS-CoV-2-specific T cell responses.

Purpose: Our aims were to determine the prevalence of physicians’ adherence to antithrombotic guidelines in the management of outpatients with chronic atrial fibrillation (AF) and to identify risk factors for nonadherence to treatment guidelines. Methods: Data on drug treatment, stroke risk factors and psychosocial variables were analyzed descriptively in a cross-sectional communitybased multicentre study. Predictors for nonadherence with guidelines for antithrombotic prophylaxis of AF patients were identified using logistic regression. Results: Of 413 outpatients with chronic AF attending the offices of family physicians, 184 (44.6%) were treated according to the American College of Chest Physicians (ACCP) 2001 guidelines. In the group of patients with a high risk of stroke (n=387), 178 patients (46.0%) received guideline-adherent treatment. 31 of the high-risk patients received coumarin although they had at least one contraindication. Multivariate analysis showed the presence of absolute contraindications to coumarins to be an independent predictor of guidelinenonadherent treatment. Conclusion: To improve guideline-adherence in the antithrombotic treatment in AF outpatients, strategies involving individual assessment of the risks and benefits will need to be established and implemented.

Background: The purpose of this trial was to evaluate the effectiveness and safety of the IL-6 receptor antibody Tocilizumab (TCZ) in the treatment of Familial Mediterranean Fever (FMF). Methods: This was a randomized, double-blinded, placebo-controlled phase II trial in adult patients with active FMF and an inadequate response or intolerance to colchicine (crFMF). The physician’s global assessment of disease activity (PGA), based on a five-point scale for six symptoms, was used as a clinical score, which had to be >2 at screening, together with elevated c-reactive protein (CRP) or erythrocyte sedimentation rate (ESR) and serum amyloid A (SAA) levels, to be eligible for inclusion. Patients were randomized 1:1 to either receive monthly TCZ or a placebo over a period of 24 weeks. The primary endpoint was the number of patients achieving an adequate response to treatment at week 16, defined as a PGA of ≤2 and normalized ESR or CRP and normalized SAA. Results: We randomized 25 patients with a median age of 31 years. At week 16, an adequate treatment response was achieved by two patients in the TCZ and none of the patients in the placebo arm (p = 0.089). SAA levels normalized with TCZ, but not with the placebo (p = 0.015). Conclusion: In this first randomized, placebo-controlled study in patients with active crFMF, more patients in the TCZ arm experienced a response to treatment in comparison to those receiving the placebo. As the prevention of amyloidosis is a major treatment goal in FMF, the normalization of SAA in TCZ-treated patients is essential. These findings have to be confirmed in a larger trial.

The SARS-CoV-2 pandemic has led to restrictions in surgical care worldwide and therefore also posed new challenges to liver surgery. The respective procedures often entail high perioperative risks and resource requirements. However, the indication for liver surgery is frequently without alternatives. To date, there is little knowledge about the impact of the pandemic on liver surgery in Germany.A retrospective data analysis of liver surgery procedures in Germany as well as transplantations was conducted. Evaluations were based on procedure codes recorded between 2010 and 2020 according to diagnosis-related groups (DRG) by the Federal Statistical Office of Germany (Destatis) and data from the German Organ Procurement Organization (Deutsche Stiftung Organtransplantation; DSO).According to DRG procedure codes relating to liver surgery recorded between 2010 and 2020 in Germany, the annual fluctuation for the first year of the pandemic 2020 remained comparable to previous years. Furthermore, the development of post-mortem liver transplantations as well as living liver donations remained stable in Germany in 2020 and 2021.The number of liver surgery procedures in Germany was subject to a dynamic development until 2020, without apparent changes in the first year of the SARS-CoV-2 pandemic. The most frequently performed liver procedures, as well as liver transplantations, remained stable with respect to their annually recorded numbers. Publication of data regarding procedures in liver surgery and transplantation in 2021 need to be awaited and analyzed to evaluate whether the observations presented in this article prove stable any further.Die Leberchirurgie ist durch ein hohes perioperatives Risiko und einen großen Ressourcenaufwand geprägt, aber die Operationsindikation ist oftmals alternativlos.

Idiopathic sudden sensorineural hearing loss (ISSNHL) is common, and defined as a sudden decrease in sensorineural hearing sensitivity of unknown aetiology. Systemic corticosteroids are widely used, however their value remains unclear. Intratympanic injections of corticosteroids have become increasingly common in the treatment of ISSNHL.To assess the effects of intratympanic corticosteroids in people with ISSNHL.The Cochrane ENT Information Specialist searched the Cochrane ENT Trials Register; CENTRAL (2021, Issue 9); PubMed; Ovid Embase; CINAHL; Web of Science; ClinicalTrials.gov; ICTRP and additional sources for published and unpublished trials (search date 23 September 2021).We included randomised controlled trials (RCTs) involving people with ISSNHL and follow-up of over a week. Intratympanic corticosteroids were given as primary or secondary treatment (after failure of systemic therapy).We used standard Cochrane methods, including GRADE to assess the certainty of the evidence. Our primary outcome was change in hearing threshold with pure tone audiometry. Secondary outcomes included the proportion of people whose hearing improved, final hearing threshold, speech audiometry, frequency-specific hearing changes and adverse effects.We included 30 studies, comprising 2133 analysed participants. Some studies had more than two treatment arms and were therefore relevant to several comparisons. Studies investigated intratympanic corticosteroids as either primary (initial) therapy or secondary (rescue) therapy after failure of initial treatment. 1. Intratympanic corticosteroids versus systemic corticosteroids as primary therapy We identified 16 studies (1108 participants). Intratympanic therapy may result in little to no improvement in the change in hearing threshold (mean difference (MD) -5.93 dB better, 95% confidence interval (CI) -7.61 to -4.26; 10 studies; 701 participants; low-certainty). We found little to no difference in the proportion of participants whose hearing was improved (risk ratio (RR) 1.04, 95% CI 0.97 to 1.12; 14 studies; 972 participants; moderate-certainty). Intratympanic therapy may result in little to no difference in the final hearing threshold (MD -3.31 dB, 95% CI -6.16 to -0.47; 7 studies; 516 participants; low-certainty). Intratympanic therapy may increase the number of people who experience vertigo or dizziness (RR 2.53, 95% CI 1.41 to 4.54; 1 study; 250 participants; low-certainty) and probably increases the number of people with ear pain (RR 15.68, 95% CI 6.22 to 39.49; 2 studies; 289 participants; moderate-certainty). It also resulted in persistent tympanic membrane perforation (range 0% to 3.9%; 3 studies; 359 participants; very low-certainty), vertigo/dizziness at the time of injection (1% to 21%, 3 studies; 197 participants; very low-certainty) and ear pain at the time of injection (10.5% to 27.1%; 2 studies; 289 participants; low-certainty). 2. Intratympanic plus systemic corticosteroids (combined therapy) versus systemic corticosteroids alone as primary therapy We identified 10 studies (788 participants). Combined therapy may have a small effect on the change in hearing threshold (MD -8.55 dB better, 95% CI -12.48 to -4.61; 6 studies; 435 participants; low-certainty). The evidence is very uncertain as to whether combined therapy changes the proportion of participants whose hearing is improved (RR 1.27, 95% CI 1.15 to 1.41; 10 studies; 788 participants; very low-certainty). Combined therapy may result in slightly lower (more favourable) final hearing thresholds but the evidence is very uncertain, and it is not clear whether the change would be important to patients (MD -9.11 dB, 95% CI -16.56 to -1.67; 3 studies; 194 participants; very low-certainty). Some adverse effects only occurred in those who received combined therapy. These included persistent tympanic membrane perforation (range 0% to 5.5%; 5 studies; 474 participants; very low-certainty), vertigo or dizziness at the time of injection (range 0% to 8.1%; 4 studies; 341 participants; very low-certainty) and ear pain at the time of injection (13.5%; 1 study; 73 participants; very low-certainty). 3. Intratympanic corticosteroids versus no treatment or placebo as secondary therapy We identified seven studies (279 participants). Intratympanic therapy may have a small effect on the change in hearing threshold (MD -9.07 dB better, 95% CI -11.47 to -6.66; 7 studies; 280 participants; low-certainty). Intratympanic therapy may result in a much higher proportion of participants whose hearing is improved (RR 5.55, 95% CI 2.89 to 10.68; 6 studies; 232 participants; low-certainty). Intratympanic therapy may result in lower (more favourable) final hearing thresholds (MD -11.09 dB, 95% CI -17.46 to -4.72; 5 studies; 203 participants; low-certainty). Some adverse effects only occurred in those who received intratympanic injection. These included persistent tympanic membrane perforation (range 0% to 4.2%; 5 studies; 185 participants; very low-certainty), vertigo or dizziness at the time of injection (range 6.7% to 33%; 3 studies; 128 participants; very low-certainty) and ear pain at the time of injection (0%; 1 study; 44 participants; very low-certainty). 4. Intratympanic plus systemic corticosteroids (combined therapy) versus systemic corticosteroids alone as secondary therapy We identified one study with 76 participants. Change in hearing threshold was not reported. Combined therapy may result in a higher proportion with hearing improvement, but the evidence is very uncertain (RR 2.24, 95% CI 1.10 to 4.55; very low-certainty). Adverse effects were poorly reported with only data for persistent tympanic membrane perforation (rate 8.1%, very low-certainty).Most of the evidence in this review is low- or very low-certainty, therefore it is likely that further studies may change our conclusions. For primary therapy, intratympanic corticosteroids may have little or no effect compared with systemic corticosteroids. There may be a slight benefit from combined treatment when compared with systemic treatment alone, but the evidence is uncertain. For secondary therapy, there is low-certainty evidence that intratympanic corticosteroids, when compared to no treatment or placebo, may result in a much higher proportion of participants whose hearing is improved, but may only have a small effect on the change in hearing threshold. It is very uncertain whether there is additional benefit from combined treatment over systemic steroids alone. Although adverse effects were poorly reported, the different risk profiles of intratympanic treatment (including tympanic membrane perforation, pain and dizziness/vertigo) and systemic treatment (for example, blood glucose problems) should be considered when selecting appropriate treatment.

Background/aim Detection of disseminated tumor cells (DTCs) after systemic treatment predicts poor prognosis in breast cancer patients. The aim of our study was to assess the expression of stem-cell marker SOX2 on DTCs and in the primary tumor of patients treated with neoadjuvant chemotherapy (NAT). Materials and methods In 170 DTC-positive patients after NAT an additional slide of bone marrow aspirate was stained by double immunofluorescence to detect SOX2-positive DTCs. The SOX2 status of the primary tumor was assessed using the same antibody. Results The SOX2-status of DTCs was determined in 62 patients and 20 of those (32%) had SOX2 positive DTCs. The SOX2 status of DTCs was not associated with any of the clinicopathological factors. A total of 36% of the patients with a SOX2-negative tumor showed SOX2-positive persistent DTCs. Conclusion SOX2-positive DTCs can be detected in breast cancer patients after NAT, even in patients with SOX2-negative primary tumors. This suggests that these populations may have evolved independently of each other.

Background Pancreatic ductal adenocarcinoma (PDAC) is a common fatal disease with unfavorable prognosis, even after oncological resection. To improve survival, adding hyperthermic intraperitoneal chemotherapy (HIPEC) has been suggested. Whether HIPEC entails disproportional short-term mortality is unknown and a prospectively determined adverse events profile is lacking. Since both pancreatic resection and HIPEC may relevantly influence morbidity and mortality, this uncontrolled single-arm, open-label, phase I/II pilot trial was designed to assess the 30-day mortality rate, treatment feasibility, and adverse events connected with HIPEC after oncological pancreatic surgery. Methods This trial recruited patients scheduled for PDAC resection. A sample size of 16 patients receiving study interventions was estimated to establish a predefined margin of treatment-associated short-term mortality with a power of > 80%. Patients achieving complete macroscopic resection received HIPEC with gemcitabine administered at 1000 mg/m2 body surface area heated to 42 °C for 1 hour. Results Within 30 days after intervention, no patient died or experienced any adverse events higher than grade 3 that were related to HIPEC. Furthermore, treatment-related adverse events were prospectively documented and categorized as expected or unexpected. This trial supports that the actual mortality rate after PDAC resection and HIPEC is below 10%. HIPEC treatment proved feasible in 89% of patients allocated to intervention. Pancreatic fistulas, as key complications after pancreas surgery, occurred in 3/13 patients under risk. Conclusion Combined pancreas resection and gemcitabine HIPEC proved feasible and safe, with acceptable morbidity and mortality. Based on these results, further clinical evaluation can be justified. Registration Number NCT02863471 (http://www.clinicaltrials.gov).

T-cell immunity is central for the control of COVID-19, in particular in patients incapable to mount a humoral immune response. We previously reported on the favorable safety profile and efficacy in terms of induction of SARS-CoV-2-specific T-cell responses by CoVac-1, a peptide-based T-cell activator, composed of SARS-CoV-2 T-cell epitopes derived from various viral proteins, combined with the toll-like receptor 1/2 agonist XS151. We conducted a Phase I/II open-label trial recruiting 54 patients with congenital or acquired B-cell deficiency who received one single subcutaneous dose of CoVac-1. Immunogenicity until day 28 in terms of CoVac-1-induced T-cell responses was the primary endpoint; safety until day 56 was assessed as secondary endpoint. Neither serious nor grade 4 CoVac-1-related adverse events were observed. The expected local granuloma formation was observed in 94% of study subjects, whereas systemic reactogenicity was mostly mild or absent. SARS-CoV-2-specific Tcell responses were induced in 86% of the patients and directed to multiple CoVac-1 peptides, not affected by any current Omicron variants and mediated by multifunctional T-helper 1 CD4+ T cells. CoVac-1-induced T-cell responses exceeded spike-specific T-cell responses after vaccination with mRNA vaccines in B-cell deficient patients and also that of immunocompetent COVID-19 convalescents with and without seroconversion. CoVac-1 induces broad and potent T-cell responses in patients with Bcell/antibody deficiency independently of current variants of concern, with a favorable safety profile. Our data warrant advancement to a pivotal Phase II/III safety and efficacy evaluation.

Purpose Active surveillance (AS) strategies for patients with low- and early intermediate-risk prostate cancer are still not consistently defined. Within a controlled randomized trial, active surveillance was compared to other treatment options for patients with prostate cancer. Aim of this analysis was to report on termination rates of patients treated with AS including different grade groups. Methods A randomized trial comparing radical prostatectomy, active surveillance, external beam radiotherapy and brachytherapy was performed from 2013 to 2016 and included 345 patients with low- and early intermediate-risk prostate cancer (ISUP grade groups 1 and 2). The trial was prematurely stopped due to slow accrual. A total of 130 patients were treated with active surveillance. Among them, 42 patients were diagnosed with intermediate-risk PCA. Reference pathology and AS quality control were performed throughout. Results After a median follow-up time of 18.8 months, 73 out of the 130 patients (56%) terminated active surveillance. Of these, 56 (77%) patients were histologically reclassified at the time of rebiopsy, including 35% and 60% of the grade group 1 and 2 patients, respectively. No patients who underwent radical prostatectomy at the time of reclassification had radical prostatectomy specimens ≥ grade group 3. Conclusion In this prospectively analyzed subcohort of patients with AS and conventional staging within a randomized trial, the 2-year histological reclassification rates were higher than those previously reported. Active surveillance may not be based on conventional staging alone, and patients with grade group 2 cancers may be recommended for active surveillance in carefully controlled trials only.

Background O6-methylguanine DNA-methyl transferase (MGMT) promoter methylation status is predictive for alkylating chemotherapy, but there are non-benefiting subgroups. Methods This is the long-term update of NOA-08 (NCT01502241), which compared efficacy and safety of radiotherapy (RT, n = 176) and temozolomide (TMZ, n = 193) at 7/14 days in patients >65 years old with anaplastic astrocytoma or glioblastoma. DNA methylation patterns and copy number variations were assessed in the biomarker cohort of 104 patients and in an independent cohort of 188 patients treated with RT+TMZ-containing regimens in Heidelberg. Results In the full NOA-08 cohort, median overall survival (OS) was 8.2 [7.0–10.0] months for TMZ treatment versus 9.4 [8.1–10.4] months for RT; hazard ratio (HR) = 0.93 (95% CI: 0.76–1.15) of TMZ versus RT. Median event-free survival (EFS) [3.4 (3.2–4.1) months vs 4.6 (4.2–5.0) months] did not differ, with HR = 1.02 (0.83–1.25). Patients with MGMT methylated tumors had markedly longer OS and EFS when treated with TMZ (18.4 [13.9–24.4] mo and 8.5 [6.9–13.3] mo) versus RT (9.6 [6.4–13.7] mo and 4.8 [4.3–6.2] mo, HR 0.44 [0.27–0.70], P < 0.001 for OS and 0.46 [0.29–0.73], P = 0.001 for EFS). Patients with glioblastomas of the methylation classes receptor tyrosine kinase I (RTK I) and mesenchymal subgroups lacked a prognostic impact of MGMT in both cohorts. Conclusion MGMT promoter methylation is a strong predictive biomarker for the choice between RT and TMZ. It indicates favorable long-term outcome with initial TMZ monotherapy in patients with MGMT promoter-methylated tumors primarily in the RTK II subgroup.

T-cell immunity is central for the control of viral infections. CoVac-1 is a peptide-based vaccine candidate, composed of SARS-CoV-2 T-cell epitopes derived from various viral proteins, combined with the toll-like receptor 1/2 agonist XS15 emulsified in MontanideTM ISA51 VG, aiming to induce superior SARS-CoV-2 T-cell immunity to combat COVID-19. We conducted a Phase I open-label trial, including 36 participants aged 18 to 80 years, who received one single subcutaneous CoVAC-1 vaccination. The primary endpoint was safety analyzed until day 56. Immunogenicity in terms of CoVac-1-induced T-cell response was analyzed as main secondary endpoint until day 28. No serious adverse events and no grade 4 adverse events were observed. Expected local granuloma formation was observed in all study subjects, while systemic reactogenicity was absent or mild. SARS-CoV-2-specific T-cell responses targeting multiple vaccine peptides were induced in all study participants, mediated by multifunctional T-helper 1 CD4+ and CD8+ T cells. CoVac-1-induced interferon-γ T-cell responses by far surpassed those detected in COVID-19 convalescents and were unaffected by current SARS-CoV-2 variants of concern (VOC). Together, CoVac-1 showed a favorable safety profile and induced broad, potent, and VOC-independent T-cell responses, supporting the presently ongoing evaluation in a Phase II trial for patients with B-cell/antibody deficiency.

This phase 3 trial compared tandem autologous stem cell transplantation (autoSCT) versus autoSCT followed by reduced-intensity conditioning allogeneic stem cell transplantation (auto/alloSCT) in patients with newly diagnosed multiple myeloma (MM) with deletion of (del) chromosome 13q (del13q). The availability/absence of a human leukocyte antigen-matched-related or matched-unrelated donor (MUD) determined the nature of the second SCT. The primary endpoint was progression-free survival (PFS) in the intention-to-treat population (n = 199). Auto/alloSCT was performed in 126 patients; 74 received MUD allografts. After 91 months median follow-up, median PFS with auto/allo versus tandem autoSCT was 34.5 versus 21.8 months (P = 0.003; adjusted hazard ratio 0.55, 95% confidence interval 0.36–0.84). Median overall survival (OS) was 70.2 versus 71.8 months (P = 0.856). Two-year non-relapse mortality with auto/allo versus tandem autoSCT was 14.3% versus 4.1% (P = 0.008). In patients harboring both del13q and del17p, median PFS and OS were 37.5 and 61.5 months with auto/allo (n = 19) versus 6.1 and 23.4 months with tandem autoSCT (n = 6) (P = 0.0002 and 0.032). Our findings suggest that auto/alloSCT significantly extends PFS versus tandem autoSCT in del13q MM, and indicate some survival benefit for first-line alloSCT in high-risk MM.

Background: Methodologically well-designed RCTs concerning the efficacy of Hypnotherapy in the treatment of Major Depression are lacking. The aim of this study was to determine whether Hypnotherapy (HT) is not inferior to Cognitive Behavioral Therapy (CBT), the gold-standard psychotherapy, in the percentage reduction of depressive symptoms, assessed in mild to moderate Major Depression (MD). Methods: This study reports the main results of a monocentric two-armed randomized-controlled rater-blind clinical trial. A total of 152 patients with MD were randomized to either CBT or HT receiving outpatient individual psychotherapy with 16 to 20 sessions for the duration of six months. The primary outcome was the mean percentage improvement in depressive symptoms assessed with the Montgomery-Asberg Depression Rating Scale (MADRS) before and after treatment. Results: The difference in the mean percentage symptom reduction between HT and CBT was 2.8 (95% CI=-9.85 to 15.44) in the Intention-to-treat sample and 4.0 (95% CI=-9.27 to 17.27) in the Per Protocol sample (N=134). Concerning the pre-specified non-inferiority margin of -16.4, both results confirm the non-inferiority of HT to CBT. The results for the follow-ups six and twelve months after the end of the treatment support the primary results. Limitations: For ethical reasons the trial did not include a control group without treatment; therefore we can only indirectly conclude that both treatment conditions are effective. Conclusion: This is the first study to demonstrate that HT was not inferior to CBT in MD, while employing rigorous methodological standards.

Background Gliomas evade current therapies through primary and acquired resistance and the effect of temozolomide is mainly restricted to methylguanin‐O6-methyltransferase promoter (MGMT) promoter hypermethylated tumors. Further resistance markers are largely unknown and would help for better stratification. Methods Clinical data and methylation profiles from the NOA‐08 (104, elderly glioblastoma) and the EORTC 26101 (297, glioblastoma) studies and 398 patients with glioblastoma from the Heidelberg Neuro‐Oncology center have been analyzed focused on the predictive effect of DNA damage response (DDR) gene methylation. Candidate genes were validated in vitro. Results Twenty‐eight glioblastoma 5'‐cytosine‐phosphat‐guanine‐3' (CpGs) from 17 DDR genes negatively correlated with expression and were used together with telomerase reverse transcriptase (TERT) promoter mutations in further analysis. CpG methylation of DDR genes shows highest association with the mesenchymal (MES) and receptor tyrosine kinase (RTK) II glioblastoma subgroup. MES tumors have lower tumor purity compared to RTK I and II subgroup tumors. CpG hypomethylation of DDR genes TP73 and PRPF19 correlated with worse patient survival in particular in MGMT promoter unmethylated tumors. TERT promoter mutation is most frequent in RTK I and II subtypes and associated with worse survival. Primary glioma cells show methylation patterns that resemble RTK I and II glioblastoma and long term established glioma cell lines do not match with glioblastoma subtypes. Silencing of selected resistance genes PRPF19 and TERT increase sensitivity to temozolomide in vitro. Conclusion Hypomethylation of DDR genes and TERT promoter mutations is associated with worse tumor prognosis, dependent on the methylation cluster and MGMT promoter methylation status in IDH wild‐type glioblastoma., Hypomethylation of DNA damage response genes correlates with worse survival in glioblastoma patients. Silencing of PRPF19 and TERT in glioblastoma in vitro models increase sensitivity to temozolomide

Background The long-term effects on neurodevelopment of the use of inhaled glucocorticoids in extremely preterm infants for the prevention or treatment of bronchopulmonary dysplasia are uncertain. Methods We randomly assigned 863 infants (gestational age, 23 weeks 0 days to 27 weeks 6 days) to receive early (within 24 hours after birth) inhaled budesonide or placebo. The prespecified secondary long-term outcome was neurodevelopmental disability among survivors, defined as a composite of cerebral palsy, cognitive delay (a Mental Development Index score of

PGRMC1 is known to be highly expressed in breast cancer tissue and is associated with chemoresistance in breast cancer cells. However, its role in breast cancer signaling is not fully understood yet. In the present study, the expression status of PGRMC1 and its phosphorylated version (pPGRMC1) in breast cancer tissue and surrounding stroma before and after neoadjuvant therapy was examined to find a possible association to therapy response. Tissue biopsies of 69 breast cancer patients were analyzed by immunohistochemistry for expression levels of PGRMC1 and pPGRMC1. Expression status of PGRMC1 and pPGRMC1 in tumor tissue was compared with expression status of progesterone receptor (PR), estrogen receptor α (ERα), total estrogen receptor β (ERβ), ERβ1, ERβ2, the proliferation marker Ki-67, and human epidermal growth factor receptor 2 (HER2/neu). Correlations were calculated for expression of PGRMC1 and pPGRMC1 before and after neoadjuvant-therapy. PGRMC1 and pPGRMC1 were highly abundant in every breast cancer tissue sample. Considerably lower signals were detected in surrounding tissue. Further, PGRMC1 and pPGRMC1 abundance was found to correlate with ERβ expression. A lower level of pPGRMC1 could be found in post-therapy surgical specimens compared to specimens before treatment. Interestingly, patients with high PGRMC1 tumor levels showed worse response to anthracycline-based therapy as patients with lower PGRMC1 levels. These new findings demonstrate that PGRMC1 might play an important role in progression and therapy resistance of human breast tumors and could offer an interesting target for anticancer therapy.

Background: Allogeneic (allo) following autologous (auto) stem-cell transplantation (SCT) has yielded conflicting results in newly diagnosed multiple myeloma (MM). In alloSCT, information is lacking regarding the impact of cytogenetic features except chromosome 13q deletion (del13q). Methods: This phase 3 trial compared tandem autoSCT versus autoSCT followed by reduced-intensity conditioning alloSCT (auto/alloSCT) in del13q MM. The availability/absence of a human leukocyte antigen-matched related or matched unrelated donor (MUD) determined the nature of the second SCT. The primary endpoint was progression-free survival (PFS) in the intent-to-treat population (n=199). Findings: Auto/alloSCT was performed in 126 patients; 74 received MUD allografts. After 91 months' median follow-up (range 2-143 months), median PFS with auto/allo versus tandem autoSCT was 34·5 versus 21.8 months (p=0·003; adjusted hazard ratio 0·55, 95% confidence interval [CI] 0·36-0·84). Median overall survival (OS) was 70.2 versus 71.8 months (p=0.856). Two-year non-relapse mortality (NRM) with auto/allo versus tandem autoSCT was 14·3% versus 4·1% (p=0·008). In patients harbouring both del13q and deletion of chromosome 17p, median PFS and OS were 37·5 and 61·5 months with auto/allo (n=19) versus 6·1 and 23·4 months with tandem autoSCT (n=6) (p=0·0002 and 0·032). Interpretation: Auto/alloSCT significantly extends PFS versus tandem autoSCT in patients with del13q MM. We believe this to be the first MM study demonstrating that MUD alloSCT can be performed with reasonable NRM. Furthermore, our data suggest some survival benefit for first-line alloSCT in high-risk MM. Funding: The trial was sponsored by Wurzburg University, Wurzburg, Germany.

Rationale Optimal secondary prevention of embolic stroke of undetermined source is not established. The current standard in these patients is acetylsalicylic acid, despite high prevalence of yet undetected paroxysmal atrial fibrillation. Aim The ATTICUS randomized trial is designed to determine whether the factor Xa inhibitor apixaban administered within 7 days after embolic stroke of undetermined source, is superior to acetylsalicylic acid for prevention of new ischemic lesions documented by brain magnetic resonance imaging within 12 months after index stroke. Design Prospective, randomized, blinded, parallel-group, open-label, German multicenter phase III trial in approximately 500 patients with embolic stroke of undetermined source. A key inclusion criterion is the presence or the planned implantation of an insertable cardiac monitor. Patients are 1:1 randomized to apixaban or acetylsalicylic acid and treated for a 12-month period. It is an event-driven trial aiming for core-lab adjudicated primary outcome events. Study outcomes The primary outcome is the occurrence of at least one new ischemic lesion identified by axial T2-weighted FLAIR magnetic resonance imaging and/or axial DWI magnetic resonance imaging at 12 months when compared with the baseline magnetic resonance imaging. Key secondary outcomes are the combination of recurrent ischemic strokes, hemorrhagic strokes, systemic embolism; combination of MACE including recurrent stroke, myocardial infarction, and cardiovascular death and combination of major and clinically relevant non-major bleeding defined according to ISTH, and change of cognitive function and quality of life (EQ-5D, Stroke Impact Scale). Discussion Embolic stroke of undetermined source is caused by embolic disease and associated with a high risk of recurrent ischemic strokes and clinically silent cerebral ischemic lesions. ATTICUS will investigate the impact of atrial fibrillation detected by insertable cardiac monitor and the effects of early anticoagulation with apixaban compared with antiplatelet therapy with acetylsalicylic acid on the incidence of new ischemic lesion after embolic stroke of undetermined source.

380 Background: Gastric cancer (GC) with peritoneal metastasis (PM) has a dismal prognosis. Palliative systemic chemotherapy (SC), usually doublet combinations of platinum and fluoropyrimidines, is the standard of care. Pressurized IntraPeritoneal Aerosol Chemotherapy with Cisplatin and Doxorubicin (PIPAC C/D) yields promising results. Here we aimed to compare overall survival (OS) between SC + PIPAC C/D vs. SC alone in patients with PM from GC. Methods: Prospective cohort of 95 consecutive patients with PM from GC treated in palliative intent at our institution from 2010 to 2018. Of these patients, 69 received SC + PIPAC C/D („PIPAC“), 26 SC alone („control“). Choice of treatment was not dictated by medical criteria, but by (non-) availability of the single-use medical devices needed for PIPAC in Russia. All patients received doublet or triplet chemotherapy with platinum together with fluoropyrimidines or capecitabin. A Cox proportional hazard model based on propensity score (PS) was used to assess the effect of PIPAC on OS and account for confounding factors. Results: The HR adjusted for PS for PIPAC vs. control was 0.396 (CI 5- 95% = 0.224-0.700, p-value 0.001). In the simple (unadjusted) Kaplan-Meier, median survival in the control group was 7.0 months (CI: 4.51 - 9.49) and in the PIPAC group 14.0 months (CI: 11.46-16.54). In the control group, all 26 patients died after 1-25 months. In the PIPAC group, 36 of 69 patients died after 4 to 20 months. The longest observed survival time in the PIPAC group was 27 months. Significance for the log-rank test after Mantel-Cox (not adjusted) was p < 0.0001. Conclusions: Compared with SC alone, intensified chemotherapy combining PIPAC C/D and SC doubled OS. These promising results need to be confirmed in a randomized trial.

Background: Cognitive behavioral therapy for psychosis (CBTp) is a specific form of psychotherapy recommended in evidence-based treatment guidelines for patients with psychosis. However, it remains unclear whether CBTp is more efficacious than unspecific psychotherapies such as supportive therapy (ST). Methods: This multicenter, single blind, randomized clinical trial used a parallel group design to compare CBTp and ST. In total, 330 patients with persistent positive symptoms were included. Participants received 20 sessions of CBTp or ST over a 9-month period. Therapy was provided in six outpatient clinics at university psychiatry departments. The primary endpoint was the severity of positive symptoms (Positive and Negative Syndrome Scale-positive) until post-treatment at 9 months after inclusion. Analysis was carried out by intention to treat with multilevel linear modeling. Findings: There was a between group effect size of g=0·33 (0·11-0·55) in favor of CBTp for positive symptoms, with pre-post effect sizes of g=0·93 (0·70-1·15) for CBTp and g=0·62 (0·40-0·84) for ST. CBTp showed favorable effects for hallucinations and social functioning, but not for negative symptoms and readmission rates. Ratings of the therapeutic relationship, number of adverse events, and antipsychotic medication did not differ between the groups. Positive symptoms decreased in both groups until the 24 month follow-up, with a between group difference of g=0·09 (-0·23-0·39). Interpretation: CBTp is more efficacious than ST in patients with persistent positive symptoms. CBTp effects cannot be explained by therapeutic attention alone. This indicates CBTp has specific mechanisms of action, and further supports the unrestricted recommendation of CBTp for the treatment of psychosis. Trial Registration Number: ISRCTN29242879 Funding Statement: The study was funded by the German ministry of education and research (grant no. 01GV0618). Declaration of Interests: All authors declare that there is no conflict of interest. Ethics Approval Statement: The study protocol was reviewed without objections by the ethics committee of the coordinating study center and the local ethics committees of all participating centers. Patients were included in the study after written informed consent was obtained, which was assured by external monitoring.

Objective Antiepileptic treatment of brain tumor patients mainly depends on the individual physician's choice rather than on well-defined predictive factors. We investigated the predictive value of defined clinical parameters to formulate a model of risk estimations for subpopulations of brain tumor patients. Methods We enclosed 650 patients > 18 years of age who underwent brain tumor surgery and included a number of clinical data. Logistic regressions were performed to determine the effect sizes of seizure-related risk factors and to develop prognostic scores for the occurrence of preoperative and early postoperative seizures. Results A total of 492 patients (334 gliomas) were eligible for logistic regression for preoperative seizures, and 338 patients for early postoperative seizures. Age ≤ 60 years (odds ratio [OR] = 1.66, p = 0.020), grades I and II glioma (OR = 4.00, p = 0.0002), total tumor/edema volume ≤ 64cm(3) (OR = 2.18, p = 0.0003), and frontal location (OR = 2.28, p = 0.034) demonstrated an increased risk for preoperative seizures. Isocitrate-dehydrogenase mutations (OR = 2.52, p = 0.026) were an independent risk factor in the glioma subgroup. Age ≥ 60 years (OR = 3.32, p = 0.041), total tumor/edema volume ≤ 64cm(3) (OR = 3.17, p = 0.034), complete resection (OR = 15.50, p = 0.0009), diencephalic location (OR = 12.2, p = 0.013), and high-grade tumors (OR = 5.67, p = 0.013) were significant risk factors for surgery-related seizures. Antiepileptics (OR = 1.20, p = 0.60) did not affect seizure occurrence. For seizure occurrence, patients could be stratified into 3 prognostic preoperative and into 2 prognostic early postoperative groups. Interpretation Based on the developed prognostic scores, seizure prophylaxis should be considered in high-risk patients and patient stratification for prospective studies may be feasible in the future.

BACKGROUND The 3-stage forehead flap technique has been described as an aesthetic improvement after nasal reconstruction compared with the 2-stage technique. A standardized evaluation of aesthetic and functional outcomes of the 2-stage versus 3-stage paramedian forehead flap after nasal reconstruction was performed. METHODS Between July 2003 and December 2012, 102 patients underwent either 2-stage or 3-stage paramedian forehead flap techniques. A standardized patient satisfaction questionnaire was used to assess resulting nasal appearance and function. Additionally, 2 plastic surgeons performed blinded assessments of the aesthetic outcome using a standardized photographic evaluation form. Together, these evaluations demonstrated functional and aesthetic outcomes (flap thickness, shape, color, flap hair growth, donor-site scars, and nasal symmetry). RESULTS Functional and aesthetic outcomes according to the self-assessment questionnaire were similar between groups. On inclusion of the surgeon's evaluation, with a greater satisfaction was apparent from the reconstructed alar of the 2-stage group (Mann-Whitney U test, p = .03, Fisher exact test, p = .024, respectively). CONCLUSION No clear evidence supported enhanced aesthetic results when the 3-stage forehead flap technique was used, especially in relation to flap thickness compared with the 2-stage technique. The 2-stage technique remains the state-of-the-art choice for nasal reconstruction, even in cases involving complex defects.

Dynamic modulations of large-scale network activity and synchronization are inherent to a broad spectrum of cognitive processes and are disturbed in neuropsychiatric conditions including Parkinson's disease. Here, we set out to address the motor network activity and synchronization in Parkinson's disease and its modulation with subthalamic stimulation. To this end, 20 patients with idiopathic Parkinson's disease with subthalamic nucleus stimulation were analysed on externally cued right hand finger movements with 1.5-s interstimulus interval. Simultaneous recordings were obtained from electromyography on antagonistic muscles (right flexor digitorum and extensor digitorum) together with 64-channel electroencephalography. Time-frequency event-related spectral perturbations were assessed to determine cortical and muscular activity. Next, cross-spectra in the time-frequency domain were analysed to explore the cortico-cortical synchronization. The time-frequency modulations enabled us to select a time-frequency range relevant for motor processing. On these time-frequency windows, we developed an extension of the phase synchronization index to quantify the global cortico-cortical synchronization and to obtain topographic differentiations of distinct electrode sites with respect to their contributions to the global phase synchronization index. The spectral measures were used to predict clinical and reaction time outcome using regression analysis. We found that movement-related desynchronization of cortical activity in the upper alpha and beta range was significantly facilitated with 'stimulation on' compared to 'stimulation off' on electrodes over the bilateral parietal, sensorimotor, premotor, supplementary-motor, and prefrontal areas, including the bilateral inferior prefrontal areas. These spectral modulations enabled us to predict both clinical and reaction time improvement from subthalamic stimulation. With 'stimulation on', interhemispheric cortico-cortical coherence in the beta band was significantly attenuated over the bilateral sensorimotor areas. Similarly, the global cortico-cortical phase synchronization was attenuated, and the topographic differentiation revealed stronger desynchronization over the (ipsilateral) right-hemispheric prefrontal, premotor and sensorimotor areas compared to 'stimulation off'. We further demonstrated that the cortico-cortical phase synchronization was largely dominated by genuine neuronal coupling. The clinical improvement with 'stimulation on' compared to 'stimulation off' could be predicted from this cortical decoupling with multiple regressions, and the reduction of synchronization over the right prefrontal area showed a linear univariate correlation with clinical improvement. Our study demonstrates wide-spread activity and synchronization modulations of the cortical motor network, and highlights subthalamic stimulation as a network-modulating therapy. Accordingly, subthalamic stimulation may release bilateral cortical computational resources by facilitating movement-related desynchronization. Moreover, the subthalamic nucleus is critical to balance inhibitory and facilitatory cortical players within the motor program.

Introduction Despite a substantial number of studies providing evidence for the efficacy of psychological treatment for mild-to-moderate depression, maximally only 50% of participants respond to treatment, even when using gold-standard treatments such as cognitive-behavioural therapy (CBT) and interpersonal therapy. New approaches such as the ‘third wave’ psychotherapies have provided promising results; however, studies concerning the comparison with evidence-based treatments are lacking. This study aims to compare the efficacy of clinical hypnotherapy (HT) with gold-standard psychotherapy (CBT) in the treatment of mild-to-moderate major depressive episodes. Methods and analysis The present study comprises a monocentric, two-armed, randomised-controlled, rater-blind (non-inferiority) clinical trial. A total of 160 participants with mild-to-moderate major depression episode will be randomly assigned to either CBT or HT involving 20 sessions of psychotherapy over a period of 24 weeks. We predict that the average improvement in the Montgomery-Åsberg Depression Rating Scale score will not be inferior in HT compared with CBT (non-inferiority hypothesis). Further outcome parameters will include the number of participants responding to treatment following the completion of treatment and 1 year after. Additionally, quality of life, treatment expectations and hypnotic susceptibility before and after end of treatment will be assessed. Ethics and dissemination The study protocol and the documents for the informed consent have been approved by the Ethics Committee of the University Hospital Tuebingen (061/2015B02). The results of this trial will be submitted for publication in peer-reviewed journals, and will be presented at national and international conferences.

Background Suitable analgesic drugs and techniques are needed for the acute care of the approximately 18 200-18 400 seriously injured patients in Germany each year. Methods This systematic review and meta-analysis of analgesia in trauma patients was carried out on the basis of randomized, controlled trials and observational studies. A systematic search of the literature over the 10-year period ending in February 2016 was carried out in the PubMed, Google Scholar, and Springer Link Library databases. Some of the considered trials and studies were included in a meta-analysis. Mean differences (MD) of pain reduction or pain outcome as measured on the Numeric Rating Scale were taken as a summarizing measure of treatment efficacy. Results Out of 685 studies, 41 studies were considered and 10 studies were included in the meta-analysis. Among the drugs and drug combinations studied, none was clearly superior to another with respect to pain relief. Neither fentanyl versus morphine (MD -0.10 with a 95% confidence interval of [-0.58; 0.39], p = 0.70) nor ketamine versus morphine (MD -1.27 [-3.71; 1.16], p = 0.31), or the combination of ketamine and morphine versus morphine alone (MD -1.23 [-2.29; -0.18], p = 0.02) showed clear superiority regarding analgesia. Conclusion Ketamine, fentanyl, and morphine are suitable for analgesia in spontaneously breathing trauma patients. Fentanyl and ketamine have a rapid onset of action and a strong analgesic effect. Our quantitative meta-analysis revealed no evidence for the superiority of any of the three substances over the others. Suitable monitoring equipment, and expertise in emergency procedures are prerequisites for safe and effective analgesia by healthcare professionals..

SPG5 is a rare subtype of Hereditary Spastic Paraplegia caused by mutations in the oxysterol-7 alpha-hydroxylase gene CYP7B1. Schols et al. study properties of lipid biomarkers in SPG5 and evaluate a treatment strategy targeting oxysterol accumulation in a randomized controlled trial (STOP-SPG5).Spastic paraplegia type 5 (SPG5) is a rare subtype of hereditary spastic paraplegia, a highly heterogeneous group of neurodegenerative disorders defined by progressive neurodegeneration of the corticospinal tract motor neurons. SPG5 is caused by recessive mutations in the gene CYP7B1 encoding oxysterol-7 alpha-hydroxylase. This enzyme is involved in the degradation of cholesterol into primary bile acids. CYP7B1 deficiency has been shown to lead to accumulation of neurotoxic oxysterols. In this multicentre study, we have performed detailed clinical and biochemical analysis in 34 genetically confirmed SPG5 cases from 28 families, studied dose-dependent neurotoxicity of oxysterols in human cortical neurons and performed a randomized placebo-controlled double blind interventional trial targeting oxysterol accumulation in serum of SPG5 patients. Clinically, SPG5 manifested in childhood or adolescence (median 13 years). Gait ataxia was a common feature. SPG5 patients lost the ability to walk independently after a median disease duration of 23 years and became wheelchair dependent after a median 33 years. The overall cross-sectional progression rate of 0.56 points on the Spastic Paraplegia Rating Scale per year was slightly lower than the longitudinal progression rate of 0.80 points per year. Biochemically, marked accumulation of CYP7B1 substrates including 27-hydroxycholesterol was confirmed in serum (n = 19) and cerebrospinal fluid (n = 17) of SPG5 patients. Moreover, 27-hydroxycholesterol levels in serum correlated with disease severity and disease duration. Oxysterols were found to impair metabolic activity and viability of human cortical neurons at concentrations found in SPG5 patients, indicating that elevated levels of oxysterols might be key pathogenic factors in SPG5. We thus performed a randomized placebo-controlled trial (EudraCT 2015-000978-35) with atorvastatin 40 mg/day for 9 weeks in 14 SPG5 patients with 27-hydroxycholesterol levels in serum as the primary outcome measure. Atorvastatin, but not placebo, reduced serum 27-hydroxycholesterol from 853 ng/ml [interquartile range (IQR) 683-1113] to 641 (IQR 507-694) (-31.5%, P = 0.001, Mann-Whitney U-test). Similarly, 25-hydroxycholesterol levels in serum were reduced. In cerebrospinal fluid 27-hydroxycholesterol was reduced by 8.4% but this did not significantly differ from placebo. As expected, no effects were seen on clinical outcome parameters in this short-term trial. In this study, we define the mutational and phenotypic spectrum of SPG5, examine the correlation of disease severity and progression with oxysterol concentrations, and demonstrate in a randomized controlled trial that atorvastatin treatment can effectively lower 27-hydroxycholesterol levels in serum of SPG5 patients. We thus demonstrate the first causal treatment strategy in hereditary spastic paraplegia.

Summary Objectives Scientific databases index numerous references related to the treatment of Kienbock's disease; yet little is known about the nature of the disease and its pathognomonic features. This study provides a cross-sectional analysis of the pattern and extent of osteonecrosis in a large cohort and a longitudinal analysis to determine the spontaneous disease progression in single patients who have not had surgical management until fragmentation of the lunate. Methods In a prospective case series, the pattern and extent of osteonecrosis were correlated with the duration of symptoms in all patients with Kienbock's disease confirmed using high-resolution 3-T magnetic resonance imaging (MRI) and ultra-thin section computed tomographic (CT) scan since 2009. Furthermore, a retrospective consecutive case series study was conducted to determine the rate of spontaneous evolution in all consecutive patients treated conservatively in our university hospital since 1990. Results Among the 35 consecutive patients with Kienbock's disease diagnosed in high-resolution 3-T MRI and ultra-thin section CT, 46% (16/35) presented degeneration of lunate cartilage on CT scan in the first 12 months following the onset of symptoms. Median wrist pain duration of patients presenting a fracture of the lunate was 14 months. Thirty-one percent (11/35) of the patients had arthritis of the lunate, yet no fractures at the time of examination. Of 106 consecutive patients with Kienbock's disease and complete records, who did not have surgical intervention until fragmentation of the lunate, three cases were identified with well-documented spontaneous courses from apparently intact lunate morphology until fragmentation within 6 months. Conclusions Kienbock's disease progresses substantially faster than previously described and, contrary to current classifications, the articular cartilage of the lunate degenerates in early stages. Level of evidence : Diagnostic accuracy, Level IV.

BACKGROUND: Multiple hypotheses regarding the cause of Kienbock disease have been proposed in seemingly contradictory small case series and cohort studies with inadequate statistical power. A prospective case-control study was conducted to analyze frequently discussed risk and causal factors. METHODS: Eighty-one consecutive patients with Kienbock disease and 198 patients with wrist ganglia were referred to the authors' clinic between 1990 and 2012, and 2003 and 2011, respectively. Patients with wrist ganglia were chosen as a control group because of the similar age distribution compared with the general population and because the common etiopathologic features of wrist ganglia and Kienbock disease can be excluded. Demographic, occupational, and medical information, including age, sex, handedness, ethnicity, education, occupation and employment status, prior treatment, and medical history were collected. Associated conditions and medication were assessed at a follow-up examination. RESULTS: Sixty-five of 81 patients with Kienbock disease and 70 of 198 controls were included in the study. Both groups were comparable with respect to age distribution and handedness. Employment status and job characteristics were similar in both groups. Hand-arm vibration during work or leisure activity over a period of 2 years was present in 23 percent with Kienbock disease and in 24 percent of 70 controls. Cortisone was used in six of 65 cases with Kienbock disease [controls, zero of 70] for an average duration of 46 months. CONCLUSIONS: Trauma, hand-arm vibration, heavy manual labor, and comorbidities were not associated with Kienbock disease. Steroid-associated Kienbock disease in six of 65 cases is consistent with the findings reported for osteonecrosis of other parts of the skeleton. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

Background An European society growing older sets the need to explore treatment options for elderly patients. Here we aimed to gather evidence on the effectiveness of a modified cognitive behavioural therapy (mCBT) in elderly schizophrenia patients as compared to treatment as usual (TAU). Methods 43 schizophrenia patients > 55y (mean 60 y), were assessed in a randomized, single blind controlled pilot trial with parallel groups: TAU+mCBT vs. TAU and intention to treat (ITT) last observation carried forward (LOCF) analysis. Subjects were recruited in Germany among in- and outpatients. MCBT comprised 30 sessions in 9 month, and a 6 month follow-up including a) physical and social activation, b) problem solving c) social skills. Primary outcomes were pre/post change in either PANSS total score, UPSA-brief score or Calgary Depression Scale for Schizophrenia. Results From 43 patients, 40 were randomized. 15 mCBT and 16 TAU-patients comprised the ITT sample. None of the primary outcome measures reached significance. When assessing effect sizes we found little pre-/post change in PANSS total score (d=0.14) and the UPSA-brief (d=0.14). Depression symptoms however improved with treatment (pre/post d=0.75 and pre/FU d=0.52). Among secondary outcomes, global assessment of functioning significantly improved in the mCBT-group pre/post (d=.074) and pre/follow-up (d=.080). Discussion Our results provide evidence for the feasibility of a sufficiently powered phase-III study targeting depressive symptoms and global functioning in long-term treated elderly schizophrenia patients. A history of about twenty years of pharmacological treatment does not imply there is no room for improvement in depression and global functioning following a modified cognitive behavioral therapy in this specific patient group.

A hypoxic microenvironment induces resistance to alkylating agents by activating targets in the mammalian target of rapamycin (mTOR) pathway. The molecular mechanisms involved in this mTOR-mediated hypoxia-induced chemoresistance, however, are unclear. Here we identify the mTOR target N-myc downstream regulated gene 1 (NDRG1) as a key determinant of resistance toward alkylating chemotherapy, driven by hypoxia but also by therapeutic measures such as irradiation, corticosteroids, and chronic exposure to alkylating agents via distinct molecular routes involving hypoxia-inducible factor (HIF)-1alpha, p53, and the mTOR complex 2 (mTORC2)/serum glucocorticoid-induced protein kinase 1 (SGK1) pathway. Resistance toward alkylating chemotherapy but not radiotherapy was dependent on NDRG1 expression and activity. In posttreatment tumor tissue of patients with malignant gliomas, NDRG1 was induced and predictive of poor response to alkylating chemotherapy. On a molecular level, NDRG1 bound and stabilized methyltransferases, chiefly O6-methylguanine-DNA methyltransferase (MGMT), a key enzyme for resistance to alkylating agents in glioblastoma patients. In patients with glioblastoma, MGMT promoter methylation in tumor tissue was not more predictive for response to alkylating chemotherapy in patients who received concomitant corticosteroids.

Background The authors systematically reviewed all of the etiopathologic factors discussed in the literature to verify the classification of de Quervain tenosynovitis on the list of occupational diseases. Methods The authors searched Ovid MEDLINE, EMBASE, and the Cochrane Library for articles discussing the cause of de Quervain tenosynovitis. The literature was classified by the level of evidence presented, the etiopathologic hypothesis discussed, the authors' conclusion about the role of the etiopathologic hypothesis, and the first author's professional background. The quality of reporting of the observational studies was evaluated by an extended Strengthening the Reporting of Observational Studies in Epidemiology statement checklist. A meta-analysis of all controlled cohort studies was performed. The Bradford Hill criteria were used to evaluate a causal relationship between de Quervain tenosynovitis and occupational risk factors. Results A total of 179 references were found, and 80 articles were included. On average, only 35 percent (median, 35 percent; range, 16 to 60 percent) of all items on the extended Strengthening the Reporting of Observational Studies in Epidemiology checklist were addressed per article. The meta-analysis to evaluate the strength of the association between de Quervain tenosynovitis and (1) repetitive, (2) forceful, or (3) ergonomically stressful manual work suggested an odds ratio of 2.89 (95 percent CI, 1.4 to 5.97; p = 0.004). No evidence was found to support the Bradford Hill criteria for a causal relationship between de Quervain tenosynovitis and occupational risk factors. Conclusion No sufficient scientific evidence was provided to confirm a causal relationship between de Quervain tenosynovitis and occupational risk factors. Clinical question/level of evidence Risk, III.

SummaryBackground Plaque psoriasis is an inflammatory disease affecting approximately 2% of the population. The clinical hallmarks of psoriasis are sharply demarcated, erythematous plaques with thick scales. Photochemotherapy (psoralen plus ultraviolet A, PUVA) is one of the most effective therapies of psoriasis. The photosensitizer 8-methoxypsoralen (8-MOP) can be applied either orally (system PUVA) or topically in a warm water bath (bath PUVA). Objectives To compare bath PUVA and system PUVA in the treatment of plaque psoriasis. Methods This was a randomized, open, prospective, multicentre trial. We included 74 patients with moderate-to-severe plaque psoriasis during a 6-week treatment and a 4-week follow-up period. Of the patients enrolled in the study, 38 received bath PUVA and 36 system PUVA. Results Both treatment modalities significantly reduced the median Psoriasis Area and Severity Index (PASI) score in the intention-to-treat population. Within 6 weeks bath PUVA reduced the median PASI by 74% (16·4 to 4·2) while system PUVA did so by 62% (15·3 to 5·8). The difference between the two modalities was not significant with regard to treatment efficacy (P = 0·389). Conclusion There is no difference between bath PUVA and system PUVA in the treatment of psoriasis.

Gait and balance disturbances typically emerge in advanced Parkinson's disease with generally limited response to dopaminergic medication and subthalamic nucleus deep brain stimulation. Therefore, advanced programming with interleaved pulses was put forward to introduce concomittant nigral stimulation on caudal contacts of a subthalamic lead. Here, we hypothesized that the combined stimulation of subthalamic nucleus and substantia nigra pars reticulata improves axial symptoms compared with standard subthalamic nucleus stimulation. Twelve patients were enrolled in this 2 × 2 cross-over double-blind randomized controlled clinical trial and both the safety and efficacy of combined subthalamic nucleus and substantia nigra pars reticulata stimulation were evaluated compared with standard subthalamic nucleus stimulation. The primary outcome measure was the change of a broad-scaled cumulative axial Unified Parkinson's Disease Rating Scale score (Scale II items 13-15, Scale III items 27-31) at '3-week follow-up'. Secondary outcome measures specifically addressed freezing of gait, balance, quality of life, non-motor symptoms and neuropsychiatric symptoms. For the primary outcome measure no statistically significant improvement was observed for combined subthalamic nucleus and substantia nigra pars reticulata stimulation at the '3-week follow-up'. The secondary endpoints, however, revealed that the combined stimulation of subthalamic nucleus and substantia nigra pars reticulata might specifically improve freezing of gait, whereas balance impairment remained unchanged. The combined stimulation of subthalamic nucleus and substantia nigra pars reticulata was safe, and of note, no clinically relevant neuropsychiatric adverse effect was observed. Patients treated with subthalamic nucleus and substantia nigra pars reticulata stimulation revealed no 'global' effect on axial motor domains. However, this study opens the perspective that concomittant stimulation of the substantia nigra pars reticulata possibly improves otherwise resistant freezing of gait and, therefore, highly warrants a subsequent phase III randomized controlled trial.
