IDH1 mutation is associated with improved resection rates, progression-free survival and overall survival in patients with anaplastic astrocytomas.

PURPOSE: The introduction of molecular markers in to the diagnosis of gliomas has changed the therapeutic approach to this tumors. The aim of this study was to examine the impact of surgery on anaplastic astrocytomas (AA), which has not previously been fully elucidated. METHODS: This was a retrospective study involving a total of 143 patients who underwent surgery for primary AA in our department between 1995 and 2020. RESULTS: Total tumor resection was achieved more often in patients with IDH-mutant tumors (41.09%) than in patients with IDH-wildtype tumors (30.76%). The median PFS was 1876 days for patients with IDH1 mutations and 238 days for patients with IDH-wildtype tumors. The 1-, 3-, 5- and 10-year PFS were longer in patients with total tumor resection and IDH-mutant AA (86.2%, 69%, 65.5% and 44.8%, respectively) than in patients with subtotal tumor resection and IDH-mutant AA (83.3%, 55.6%, 41.7% and 25%, respectively) and even longer compared to all IDH-wildtype tumors. The median OS was 2472 days for patients with IDH1 mutations and 434 days for patients with IDH-wildtype tumors. The 3-, 5- and 10-year OS times were longer in patients with total tumor resection and IDH-mutant AA (89.2%, 85.2% and 72.6%, respectively) than in patients with subtotal tumor resection and IDH-mutant AA (85.9%, 73.7% and 52.6%, respectively) and were even longer compared to all IDH-wildtype tumors. CONCLUSION: Total tumor resection is more common with IDH-mutant AA than with IDH-wildtype tumors. Patients with IDH-mutant AA had significantly better PFS and OS after total tumor resection than after subtotal tumor resection and biopsy.

Sociodemographic and Environmental Determinants of Regional Prevalence of Psoriasis in Germany: A Spatiotemporal Study of Ambulatory Claims Data.

There are regional differences in the prevalence of psoriasis between countries, as well as within countries. However, regional determinants of differences in prevalence are not yet understood. The aim of this study was to identify sociodemographic and environmental determinants of regional prevalence rates for psoriasis. Analyses were based on German outpatient billing data from statutory health insurance, together with data from databases on sociodemographic and environment factors at the county level (N = 402) for 2015-2017. Descriptive statistics were calculated for all variables. To identify determinants for prevalence at the county level, spatiotemporal regression analysis was performed, with prevalence as the dependent variable, and the number of physicians, mean age, mean precipitation, sunshine hours, mean temperature, level of urbanity, and the German Index of Socioeconomic Deprivation (GISD) as independent variables. Mean prevalence of psoriasis increased from 168.63 per 10,000 in 2015 to 173.54 per 10,000 in 2017 for Germany as a whole, with high regional variation. Five determinants were detected (p < 0.05). The prevalence increased by 4.18 per 10,000 persons with SHI with each GISD unit, and by 3.76 per 10,000 with each year increase in age. Each additional hour of sunshine resulted in a decrease of 0.04 and each °C increase in mean temperature resulted in an increase of 4.22. Each additional dermatologist per 10,000 inhabitants resulted in a decrease of 0.07. In conclusion, sociodemographic and environmental factors result in significant differences in prevalence of psoriasis, even within-country.

Which factors influence the participation in statutory skin cancer screenings in Germany?

BACKGROUND AND OBJECTIVES: Due to increasing skin cancer incidence, Germany implemented a statutory nationwide routine skin cancer screening (rSCS) in 2008. The present study aims (1) to analyze which patient factors are associated with the participation in rSCS in Germany and (2) to investigate reasons for nonparticipation. PATIENTS AND METHODS: Participants and nonparticipants of rSCS (≥ 35 years) were recruited in routine care in nine dermatological outpatient clinics. Reasons for (non-)participation, knowledge about skin cancer as well as clinical and socioeconomic data were obtained. Stratified by groups, descriptive analyses and binary logistic regression analyses for associations with participation were performed. RESULTS: Of the 294 rSCS participants and 162 non-participants, 46.5% were male with a mean age of 54.5 ± 12.7 years. In total, 87.1% had sunburns in childhood and 47.1% used sunbeds before. Higher age, female gender, previous sunbed use, and concern for and knowledge of skin cancer were significantly associated with previous rSCS participation. Of the non-participants, 46% were unaware of the option for free rSCS and 40% justified their nonparticipation on the basis of feeling healthy. CONCLUSIONS: The reasons for nonparticipation in rSCS, such as sociodemographic characteristics and risk behavior, should be known in order to optimize rSCS programs.

Moral Distress in Radiation Oncology: Insights From Residents in Germany.

Purpose: Being challenged by circumstances that force one to act in discordance with one's moral compass can lead to moral distress. The phenomenon has been widely investigated among nurses. This study was designed to shed some light on the situation of resident physicians in radiation oncology. Methods and Materials: To gain insight into moral distress among residents in radiation oncology, a web-based questionnaire was developed and distributed throughout Germany. Participants were asked to evaluate possible burdensome situations and different options for relief. To outline the main issues of moral distress, an exploratory factor analysis was conducted. Relief options were examined by frequencies. Results: The factor analysis yielded lack of time, contradiction between patient request and indication, nonmedical interests, and decisions between curative treatment and best supportive care as main issues for the 84 participants. Support from supervisors and senior physicians, as well as exchanges with resident colleagues were indicated as forms of relief. Professional support, such as ethics consultations, structured conversation groups (Balint), or psychological case supervisions, were rated as less helpful, although most participants reported a lack of experience with these. Conclusions: The results are in accordance with existing assumptions that moral distress among physicians is mainly due to uncertainty. Regarding radiation oncology residents in particular, moral distress seems to be related to uncertainty in decisions and conflicts about treatment options. Although senior physicians and supervisors present important role models in dealing with moral distress, professional services such as ethics consultations offer an opportunity for relief that can still be expanded.

Perception and Impact of COVID-19 Pandemic in Psoriasis Patients: Data from the German PsoBest and the CoronaBest Registries.

Background: Limited data are available characterizing the impact of the SARS-CoV-2 pandemic on psoriasis care for patients in Germany. Objective: To analyze patient perception and impact of the pandemic on well-being and psoriasis management of German patients with moderate-to-severe psoriasis or psoriasis arthritis under systemic therapies. Methods: The CoronaBest registry captures events of SARS-CoV-2 infections and analyzes the impact of the pandemic on patients with psoriasis or psoriasis arthritis. In June 2020, and independently in February 2022, patients with psoriasis or psoriasis arthritis received a standardized questionnaire for current treatment, protective measures, well-being, and individual risks for COVID-19, among others. Results: Included were 4,194 patients in 2020 (mean age of 47.7 years and 41.8% women) and 4,818 patients in 2022 (mean age of 56.4 and 42.9% women). Treatment discontinuations were observed in 2.7% and 1.7% of patients in 2020 and 2022, respectively. In the vast majority of the cases (>92%), no additional measures were taken concerning the management of psoriasis treatments in either 2020 or 2022. Those patients with changes reported most frequently: telephone calls instead of face-to-face visits (80.2%, in 2020 vs 40.5% in 2022) or more frequent controls (27.1%, 2020 vs 22.0%, 2022). A majority (66.7%, 2020, and 70.6%, 2022) did not perceive the virus as a considerable threat. The proportion of patients feeling well informed about COVID-19 by physicians increased from 42.6% in 2020 to 51.8% in 2022. About 81.1% of patients in 2020 and 67.5% in 2022 stated that their overall personal condition was not affected due to the pandemic. Physicians attributed no special risk of contracting SARS-CoV-2 in most of the patients. Conclusion: A high rate of systemic treatment persistence and awareness of risks and protective measures indicate that health care for psoriasis largely followed current national and international recommendations during the COVID-19 pandemic.

Tricuspid Regurgitation and TAVR: Outcomes, Risk Factors and Biomarkers.

Background. The significance of concomitant tricuspid regurgitation (TR) in the context of transcatheter aortic valve replacement (TAVR) remains unclear. This study aimed to analyze the severity of TR before and after TAVR with regard to short- and long-term survival and to analyze the influencing factors. Methods. In our retrospective analysis, TR before and after TAVR was examined and patients were classified into groups accordingly. Special attention was paid to patients with post-interventional changes in TR. Mortality after TAVR was considered the primary endpoint of the analysis and major complications according to the Valve Academic Research Consortium 3 (VARC3) were compared. Moreover, biomarkers and risk factors for worsening or improvement of TR through TAVR were analyzed. Results. Among 775 patients who underwent TAVR in our center between January 2009 and December 2019, 686 patients (89%) featured low- and 89 patients (11%) high-grade TR. High-grade pre-TAVR TR was associated with worse short- (30-day), mid- (2-year) and long-term survival up to 8 years. Even though in nearly half of the patients with high-grade TR the regurgitation improved within seven days after TAVR (n = 42/89), this did not result in a survival benefit for this subgroup. On the other hand, a worsening of low-grade TR was seen in more than 10% of the patients (n = 73/686), which was also associated with a worse prognosis. Predictors of worsening of TR after TAVR were adipositas, impaired right ventricular function and the presence of mild TR. Age, atrial fibrillation, COPD, impaired renal function and elevated cardiac biomarkers were risk factors for mortality after TAVR independent from the grade of TR. Conclusions. Not only pre-interventional, but also post-TAVR high-grade TR is associated with a worse prognosis after TAVR. TAVR can change concomitant tricuspid regurgitation, but improvement does not have any impact on short- and long-term survival. Worsening of TR after TAVR is possible and impairs the prognosis.
