Integrated psychological therapy: effectiveness in schizophrenia inpatient settings related to patients' age
Elderly people with schizophrenia often suffer from cognitive impairments, which affect their social functioning. Today, only a few therapy approaches for middle-aged and older patients are available. The Integrated Psychological Therapy (IPT) combines neurocognitive and social cognitive interventions with social skills approaches. The aim of this study was to evaluate (1) whether IPT is effective in younger patients (age < 40 years) and middle-aged patients (age ℠40 years) and (2) whether control conditions (treatment as usual or unspecific group activities) reveal some change in outcome depending on age

How to classify, diagnose, treat and follow-up extragonadal germ cell tumors? A systematic review of available evidence
Purpose To present the current evidence and the development of studies in recent years on the management of extragonadal
germ cell tumors (EGCT).
Methods A systematic literature search was conducted in Medline and the Cochrane Library. Studies within the search
period (January 2010 to February 2021) that addressed the classifcation, diagnosis, prognosis, treatment, and follow-up of
extragonadal tumors were included. Risk of bias was assessed and relevant data were extracted in evidence tables.
Results The systematic search identifed nine studies. Germ cell tumors (GCT) arise predominantly from within the testis,
but about 5% of the tumors are primarily located extragonadal. EGCT are localized primarily mediastinal or retroperitoneal
in the midline of the body. EGCT patients are classifed according to the IGCCCG classifcation. Consecutively, all mediastinal non-seminomatous EGCT patients belong to the âpoor prognosisâ group. In contrast mediastinal seminoma and both
retroperitoneal seminoma and non-seminoma patients seem to have a similar prognosis as patients with gonadal GCTs and
metastasis at theses respective sites. The standard chemotherapy regimen for patients with a EGCT consists of 3â4 cycles
(good vs intermediate prognosis) of bleomycin, etoposid, cisplatin (BEP); however, due to their very poor prognosis patients
with non-seminomatous mediastinal GCT should receive a dose-intensifed or high-dose chemotherapy approach upfront
on an individual basis and should thus be referred to expert centers Ifosfamide may be exchanged for bleomycin in cases of
additional pulmonary metastasis due to subsequently planned resections. In general patients with non-seminomatous EGCT,
residual tumor resection (RTR) should be performed after chemotherapy.
Conclusion In general, non-seminomatous EGCT have a poorer prognosis compared to testicular GCT, while seminomatous
EGGCT seem to have a similar prognosis to patients with metastatic testicular seminoma. The current insights on EGCT are
limited, since all data are mainly based on case series and studies with small patient numbers and non-comparative studies.
In general, systemic treatment should be performed like in testicular metastatic GCTs but upfront dose intensifcation of
chemotherapy should be considered for mediastinal non-seminoma patients. Thus, EGCT should be referred to interdisciplinary centers with utmost experience in the treatment of germ cell tumors
Can magnetic resonance imaging replace conventional computerized tomography for follow-up of patients with testicular cancer? A systematic review
Purpose
Follow-up protocols for patients with testicular cancer (TC) have significantly reduced the number of cross-sectional imaging studies to reduce radiation exposure. At present, it is unclear whether magnetic resonance imaging (MRI) could replace conventional computerized tomography (CT) imaging. The objective of this study is to summarize the scientific evidence on this topic and to review guideline recommendations with regard to the use of MRI.
Methods
A systematic literature review was performed searching Medline and Cochrane databases for prospective studies on patients with TC in the follow-up care (last search in February 2021). Additionally, guideline recommendations for TC were screened. Data extraction and quality assessment of included studies were performed and used for a descriptive presentation of results.
Results
A total of four studies including two ongoing trials were identified. Overall, the scientific evidence of prospective comparative studies is based on 102 patients. Data suggest that abdominal imaging with MRI can replace conventional CT for detection of lymph node metastasis of the retroperitoneum to spare radiation exposure and contrast media application. However, experienced radiologists are needed. Clinical guidelines are aware of the risk of diagnosis-induced secondary malignancy due to CT imaging and some have adapted their recommendations accordingly. Results of the two ongoing trials on 738 patients are expected soon to provide more reliable results on this topic.
Conclusions
There is growing evidence that abdominopelvic MRI imaging can replace CT imaging during follow-up of patients with TC in order to reduce radiation exposure and diagnosis-induced secondary malignancy
First-line salvage treatment options for germ cell tumor patients failing stage-adapted primary treatment : A comprehensive review compiled by the German Testicular Cancer Study Group
Purpose
In this review, we summarize and discuss contemporary treatment standards and possible selection criteria for decision making after failure of adjuvant or first-line cisplatin-based chemotherapy for primarily localized or metastatic germ cell tumors.
Methods
This work is based on a systematic literature search conducted for the elaboration of the first German clinical practice guideline to identify prospective clinical trials and retrospective comparative studies published between Jan 2010 and Feb 2021. Study end points of interest were progression-free (PFS) and overall survival (OS), relapse rate (RR), and/or safety.
Results
Relapses of clinical stage I (CS I) patients irrespective of prior adjuvant treatment after orchiectomy are treated stage adapted in accordance for primary metastatic patients. Surgical approaches for sole retroperitoneal relapses are investigated in ongoing clinical trials. The appropriate salvage chemotherapy for metastatic patients progressing or relapsing after first-line cisplatin-based chemotherapy is still a matter of controversy. Conventional cisplatin-based chemotherapy is the international guideline-endorsed standard of care, but based on retrospective data high-dose chemotherapy and subsequent autologous stem cell transplantation may offer a 10â15% survival benefit for all patients. Secondary complete surgical resection of all visible residual masses irrespective of size is paramount for treatment success.
Conclusions
Patients relapsing after definite treatment of locoregional disease are to be treated by stage-adapted first-line standard therapy for metastatic disease. Patients with primary advanced/metastatic disease failing one line of cisplatin-based combination chemotherapy should be referred to GCT expert centers. Dose intensity is a matter of ongoing debate, but sequential high-dose chemotherapy seems to improve patientsâ survival
FĂŒhrungsverantwortung in der Hochschullehre : Zur Situation in den MINT-FĂ€chern und Wirtschaftswissenschaften an UniversitĂ€ten in Baden-WĂŒrttemberg, Rheinland-Pfalz und ThĂŒringen
Manche Studierende sind die Chefs von morgen. Sie mĂŒssen Unternehmensziele erreichen und Gewinn erwirtschaften. Gleichzeitig fĂŒhren sie Mitarbeiter und Mitarbeiterinnen und mĂŒssen ihrer Verantwortung gerecht werden. Doch UniversitĂ€ten bereiten kaum auf eine spĂ€tere FĂŒhrungsverantwortung vor, das ist eines der zentralen Ergebnisse der empirischen Studie âFĂŒhrungsethik als Ethik in den Wissenschaftenâ. An der von der Carl-Zeiss-Stiftung geförderten Studie waren die UniversitĂ€ten TĂŒbingen, Mainz und Jena beteiligt. Gut eineinhalb Jahre lang forschten Wissenschaftlerinnen und Wissenschaftler aus Philosophie, Politikwissenschaft, Soziologie und Wirtschaftswissenschaft gemeinsam zur Frage: Inwiefern bereiten UniversitĂ€ten ihre Studierenden im Rahmen eines Fachstudiums auf spĂ€tere FĂŒhrungsverantwortung vor? Untersucht wurden ĂŒber 600 mathematisch-naturwissenschaftliche, ingenieurwissenschaftliche und wirtschaftswissenschaftliche Bachelor- und Master-StudiengĂ€nge. Interviews mit Expert_innen aus dem Hochschulbereich ergĂ€nzten die Untersuchung. Auch FĂŒhrungskrĂ€fte aus der freien Wirtschaft brachten ihre Expertise ein
Therapy of clinical stage IIA and IIB seminoma: a systematic review
Purpose
The optimal treatment for clinical stage (CS) IIA/IIB seminomas is still controversial. We evaluated current treatment options.
Methods
A systematic review was performed. Only randomized clinical trials and comparative studies published from January 2010 until February 2021 were included. Search items included: seminoma, CS IIA, CS IIB and therapy. Outcome parameters were relapse rate (RR), relapse-free (RFS), overall and cancer-specific survival (OS, CSS). Additionally, acute and long-term side effects including secondary malignancies (SMs) were analyzed.
Results
Seven comparative studies (one prospective and six retrospective) were identified with a total of 5049 patients (CS IIA: 2840, CS IIB: 2209). The applied treatment modalities were radiotherapy (RT) (nâ=â3049; CS IIA: 1888, CSIIB: 1006, unknown: 155) and chemotherapy (CT) or no RT (nâ=â2000; CS IIA: 797, CS IIB: 1074, unknown: 129). In CS IIA, RRs ranged from 0% to 4.8% for RT and 0% for CT. Concerning CS IIB RRs of 9.5%â21.1% for RT and of 0%â14.2% for CT have been reported. 5-year OS ranged from 90 to 100%. Only two studies reported on treatment-related toxicities.
Conclusions
RT and CT are the most commonly applied treatments in CS IIA/B seminoma. In CS IIA seminomas, RRs after RT and CT are similar. However, in CS IIB, CT seems to be more effective. Survival rates of CS IIA/B seminomas are excellent. Consequently, long-term toxicities and SMs are important survivorship issues. Alternative treatment approaches, e.g., retroperitoneal lymph node dissection (RPLND) or dose-reduced sequential CT/RT are currently under prospective investigation
Retrospective Analysis of Radiological Recurrence Patterns in Glioblastoma, Their Prognostic Value And Association to Postoperative Infarct Volume
Recent studies suggested that postoperative hypoxia might trigger invasive tumor growth, resulting in diffuse/multifocal recurrence patterns. Aim of this study was to analyze distinct recurrence patterns and their association to postoperative infarct volume and outcome. 526 consecutive glioblastoma patients were analyzed, of which 129 met our inclusion criteria: initial tumor diagnosis, surgery, postoperative diffusion-weighted imaging and tumor recurrence during follow-up. Distinct patterns of contrast-enhancement at initial diagnosis and at first tumor recurrence (multifocal growth/progression, contact to dura/ventricle, ependymal spread, local/distant recurrence) were recorded by two blinded neuroradiologists. The association of radiological patterns to survival and postoperative infarct volume was analyzed by uni-/multivariate survival analyses and binary logistic regression analysis. With increasing postoperative infarct volume, patients were significantly more likely to develop multifocal recurrence, recurrence with contact to ventricle and contact to dura. Patients with multifocal recurrence (Hazard Ratio (HR) 1.99, P = 0.010) had significantly shorter OS, patients with recurrent tumor with contact to ventricle (HR 1.85, P = 0.036), ependymal spread (HR 2.97, P = 0.004) and distant recurrence (HR 1.75, P = 0.019) significantly shorter post-progression survival in multivariate analyses including well-established prognostic factors like age, Karnofsky Performance Score (KPS), therapy, extent of resection and patterns of primary tumors. Postoperative infarct volume might initiate hypoxia-mediated aggressive tumor growth resulting in multifocal and diffuse recurrence patterns and impaired survival
Prognostic value of tumour volume in patients with a poor Karnofsky performance status scale â a bicentric retrospective study
Backround: Median overall survival (OS) after diagnosis of glioblastoma (GBM) remains 15 months amongst patients receiving aggressive surgical resection, chemotherapy and irradiation. Treatment of patients with a poor preoperative Karnofsky Performance Status Scale (KPSS) is still controversial. Therefore, we retrospectively assessed the outcome after surgical treatment in patients with a KPSS of â€60%. Methods: We retrospectively included patients with a de-novo glioblastoma WHO °IV and preoperative KPSS â€60%, who underwent surgery at two neurosurgical centres between September 2006 and March 2016. We recorded pre- and postoperative tumour volume, pre- and postoperative KPSS, OS, age and MGMT promoter status. Results: One hundred twenty-three patients (58 females/65 males, mean age 67.4 ± 13.4 years) met the inclusion criteria. Seventy-five of the 123 patients (61%) underwent surgical resection. 48/123 patients (39%) received a biopsy. The median preoperative and postoperative tumour volume of all patients was 33.0 ± 31.3 cm3 (IR 15.0â56.5cm3) and 3.1 ± 23.8 cm3 (IR 0.2â15.0 cm3), respectively. The median KPSS was 60% (range 20â60%) preoperatively and 50% (range 0â80%) postoperatively. Patients who received a biopsy showed a median OS for patients who received a biopsy only was 3.0 months (95% CI 2.0â4.0 months), compared to patients who had a resection and had a median OS of 8 months (95% CI 3.1â12.9 months). Age (p < 0.001, HR: 1.045 [95% CI 1.022â1.068]), postoperative tumour volume (p = 0.02, HR: 1.016 [95% CI 1.002â1.029]) and MGMT promotor status (p = 0.016, HR: 0.473 [95% CI 0.257â0.871]) were statistically significant in multivariate analysis. In subgroup analyses only age was shown as a significant prognostic factor in multivariate analyses for patients receiving surgery (p < 0.001, HR: 1.046 [95% CI 1.022â1.072]). In the biopsy group no significant prognostic factors were shown in multivariate analysis. Conclusion: GBM patients with a preoperative KPSS of â€60% might profit from surgical reduction of tumour burden
