Dresden to "Down Under": The Career of German Dermatologist Erwin Oppenheim.

Erwin Oppenheim (1893-1975) was a successful dermatologist in Dresden, Germany. He with his family fled the country in 1939 because of National Socialism and settled in Melbourne in the Australian state of Victoria. The regulations of Australian universities and medical boards of that era in relation to refugee medicos hindered Oppenheim's registration as a medical practitioner. He was permitted to treat skin conditions, but not allowed to prescribe medications other than some topical preparations. In spite of these restrictions, Oppenheim soon established a busy private practice. He also contributed to dermatology by providing guidance to "Ego Pharmaceuticals," a large company formed by Oppenheim's son and daughter-in-law in 1953 that produces a range of skin and other healthcare products for Australian and global markets.

Best timing of bilateral total hip arthroplasty - an analysis of revision and mortality rates from the German Arthroplasty Registry (EPRD).

BACKGROUND: The burden of osteoarthritis (OA) in multiple joints is high and for patients with bilateral OA of the hip there is no clear recommendation about the indication for simultaneous (one-stage) bilateral total hip arthroplasty (THA) versus two-staged procedures. The purpose of this study was therefore to compare revision and mortality rates after different strategies of surgical timing in bilateral hip OA from the German Arthroplasty Registry (EPRD). METHODS: Since 2012 22,500 patients with bilateral THA (including 767 patients with one-staged bilateral surgery and 11,796 patients with another separate procedures within one year after first THA) are documented in the registry. The patients who underwent simultaneous bilateral THA were matched with a cohort of 767 patients who underwent the second THA between 1 and 90 days postoperatively (short interval) and another cohort of 4,602 patients with THA between 91 and 365 days postoperatively (intermediate interval). Revision for all reasons and mortality rates were recorded. Cox regression was performed to evaluate the influence of different patient characteristics. RESULTS: The cumulative 5-year revision rate for patients with simultaneous bilateral THA was 1.8% (95% CI 0.9-2.6), for patients with two-staged THA 2.3% (95% CI 1.0-3.6) in the short interval and 2.5% (95% CI 2.1-2.9) in the intermediate interval, respectively. In all three groups, patients who underwent THA in a high-volume center (≥ 500 THA per year) had a significant lower risk for revision (HR 0.687; 95% CI 0.501-0.942) compared to surgeries in a low-volume center (< 250 THA per year). There was no significant difference regarding cumulative mortality rates in the three cohorts. Higher age (HR 1.060; 95% CI 1.042-1.078) and severe comorbidities as reflected in the Elixhauser Score (HR 1.046; 95% CI 1.014-1.079) were associated with higher mortality rates after simultaneous THA. CONCLUSION: Simultaneous bilateral THA seems to be a safe procedure for younger patients with limited comorbidities who have bilateral end-stage hip OA, especially if performed in high-volume centers. LEVEL OF EVIDENCE: III.

Investigating seasonal changes in factors associated with COVID-19 concerns: Results from a serial cross-sectional survey study in Germany between 2020 and 2023.

Objective: COVID-19 risk perceptions are discussed to be volatile and have been shown to be connected to the adoption of preventive public health behaviors. This study aimed to investigate changes in COVID-19 concerns and influencing factors as a function of season among the German public. Methods: Sixty-three waves of cross-sectional telephone surveys with German participants aged 14 years and older conducted at least monthly between June 2020 and April 2023 provided the data basis (N = 63,471). After pooling participants of different waves by season (spring, summer, fall, winter), data were analyzed with regard to changes in physical health, mental health, economic, and social COVID-19 concerns. Individual characteristics (e.g., age), COVID-19 behavior (e.g., hygiene practices), and related perceptions (e.g., controllability of risk) were considered as predictors of composite concerns in different seasons. Results: Results showed a higher between-seasons than within-seasons variability in concerns, with rises in physical and mental health and social concerns during fall. Multivariate regressions revealed being female, lower education, adopting protective measures, and higher perceived probability of infection in both public and private settings to be consistent predictors of higher COVID-19 concerns. Coefficients of these predictors remained comparatively stable over seasons and years. Conclusion: Results indicate re-occurring changes in concerns during a prolonged crisis, with distinct characteristics being consistently associated with higher reported concerns. To ensure the application of protective measures, communicators should consider that risk perceptions are subject to fluctuations, but that certain groups of individuals tend to develop them and therefore deserve particular focus.

Influence parental- and child-related factors on the acceptance of SARS-CoV-2 test methods in schools and daycare facilities.

Introduction: Rapid testing for Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infections was an essential step in reducing the spread of the virus and monitoring pandemic development. Most mandatory standard pandemic testing in Germany has been performed in schools and daycare facilities. We investigated the influence of behavioral and attitudinal characteristics of children and caregivers on their acceptance of (i) antigen-based nasal swab rapid and (ii) oral saliva-based pooled Polymerase Chain Reaction (PCR) tests. Methods: Conducted through a cross-sectional survey between November and December 2021, with 1962 caregivers and 581 children/adolescents participating, the study evaluated the acceptability of each testing method on a six-point scale. Participants scored one test method conducted on their child at one of six levels with 1 and 6 denoting "excellent" (1) and "inadequate" (6), respectively. We considered demographic variables, vaccination status, child mental health (measured by the SDQ-questionnaire), and facility type (kindergarten, primary school, secondary school) as covariates. Results: Results reveal a preference for saliva-based PCR tests over nasal swabs by about one grade, particularly among parents of unvaccinated children, especially if their child expressed future vaccination reluctance. Testing acceptance was lower among children with mental health issues, primary school-aged, and those with less-educated parents. Perception of test accuracy and convenience influenced attitudes, favoring saliva-based PCR tests. Moreover, children with mental health issues felt less secure during testing. Discussion: To our knowledge, this is the first study to investigate the influence of different testing methods on testing acceptance for SARS-CoV-2 in children and caregivers. Our study identifies predictors of lower acceptance of public health surveillance measures and enables the development of educational programs on testing and vaccination tailored to the needs of specific target groups. Moreover, we demonstrate that test acceptance in vulnerable groups can be enhanced by careful choice of an appropriate testing method.

Prevalence of tick-borne bacterial pathogens in Germany-has the situation changed after a decade?

Introduction: Tick-borne pathogens, such as Borreliella spp., Rickettsia spp., and Anaplasma spp., are frequently detected in Germany. They circulate between animals and tick vectors and can cause mild to severe diseases in humans. Knowledge about distribution and prevalence of these pathogens over time is important for risk assessment of human and animal health. Methods: Ixodes ricinus nymphs were collected at different locations in 2009/2010 and 2019 in Germany and analyzed for tick-borne pathogens by real-time PCR and sequencing. Results: Borreliella spp. were detected with a prevalence of 11.96% in 2009/2010 and 13.10% in 2019 with B. afzelii and B. garinii as dominant species. Borrelia miyamotoi was detected in seven ticks and in coinfection with B. afzelii or B. garinii. Rickettsia spp. showed a prevalence of 8.82% in 2009/2010 and 1.68% in 2019 with the exclusive detection of R. helvetica. The prevalence of Anaplasma spp. was 1.00% in 2009/2010 and 7.01% in 2019. A. phagocytophilum was detected in seven tick samples. None of the nymphs were positive for C. burnetii. Discussion: Here, observed changes in prevalence were not significant after a decade but require longitudinal observations including parameters like host species and density, climatic factors to improve our understanding of tick-borne diseases.

[Surgical Treatment of Oropharyngeal Cancer - Recommendations of the Current German S3 Guideline, Part I]. / Chirurgische Therapie des Oropharynxkarzinoms: Empfehlungen der aktuellen S3-Leitlinie ­ Teil I.

In general, a trend towards transoral resection (as opposed to classic open approaches) + neck dissection + adjuvant radio- (chemo-) therapy has been observed for oropharyngeal carcinoma over the last 20 years. Techniques of transoral surgery (TOS), including transoral laser microsurgery (TLM) and transoral robotic surgery (TORS) have been propagated in retrospective comparisons with conventional surgery or primary radiochemotherapy as gentle, minimally invasive procedures with good late functional results. Meta-analyses of mostly uncontrolled retrospective analyses suggest that TORS may have better disease-free survival (DFS) and a reduced risk of free flap reconstruction compared with open surgery. TORS (TOS) was associated with fewer tumor-positive resection margins (R1), a lower number of recurrences, fewer intraoperative tracheostomies, a shorter inpatient stay and a shorter duration of postoperative nasal tube feeding compared to open surgery. In principle, based on the best evidence currently available from registry studies, stage I-II oropharyngeal carcinomas can be treated either with primary surgery or radiochemotherapy with a comparable chance of survival. With comparable evidence for stage III and IVa, p16neg. oropharyngeal carcinomas, the majority of authors advocate primary surgery followed by adjuvant radiotherapy or radiochemotherapy as the treatment of first choice. For p16pos. patients the results of registry studies are inconsistent, although the largest registry study on 450 HPV-positive stage III patients shows a significant superiority of primary surgery + adjuvant radiochemotherapy. Since all registry studies did not adjust for smoking status, among other factors, the current data situation should be evaluated with the necessary caution.

Dealing with the challenges of the pandemic - results of a population-based survey during the second year of the COVID-19 pandemic contrasting benefits and burden.

BACKGROUND: The pandemic and the associated consequences have been ongoing stressors with severe impacts on the population and particularly on families. Research focusing on groups dealing well with the challenges of the pandemic is scarce. Here, we aimed to identify groups being well-adjusted during the pandemic and associated predictors. METHODS: A representative sample of the German population (N = 2,515, 51.6% women, 50.09 years), and a subsample of persons with children or adolescents under the age of 18 (N = 453, 60.3% women, 40.08 years) was assessed from July to October 2021. As huge differences in coping with the pandemic are seen, cluster analysis was performed. RESULTS: Persons in the "well-adjusted cluster" were characterized by higher quality of life, better coping with the pandemic and lower burden of the pandemic. The family subsample well-adjusted cluster was characterized by lower pandemic-associated burden, lower parental stress compared to before the pandemic and a better relationship with the child. Fewer mental health symptoms and less pandemic-associated negative impact on career predicted membership of the well-adjusted cluster in both samples. An interaction between mental health symptoms and the negative impact of COVID-19 on the career was found. CONCLUSIONS: Our results underscore the importance of mental health and work-related factors for coping with the pandemic.

Dimensions of Evidence-Based Practice in Nursing: Results of a Factor Analysis.

Clinical decision support systems (CDSS) are capable of bridging evidence and practice. However, it is unclear what dimensions determine evidence-based practice under real world conditions. To answer this question, 126 registered nurses and nursing students from the Munich municipal hospital group filled in a systematically developed and validated questionnaire with 26 items. An exploratory factor analysis revealed the three dimensions "Knowledge", "Trust" and "Practice" which explain 56.5% of the total variance. They are corroborated by the literature and match findings about evidence-based practice in medicine. These results not only provide insights into the construct evidence-based practice but also give practical hints how to foster evidence-based daily work in nursing. A supportive clinical environment seems to be paramount to achieve this goal: access to evidence-based resources, team meetings to reflect the experience and the inclusion of the patients' needs.

Association between continuity of care and inappropriate prescribing in outpatient care in Germany: a cross-sectional analysis conducted as part of the LoChro trial.

OBJECTIVES: Potentially inappropriate medications (PIMs) and potential prescribing omissions (PPOs) are common in multimorbid patients. This study aims to describe PIMs and PPOs in an open-access outpatient setting and to investigate any association between continuity of care (CoC) and PIMs and PPOs in multimorbid older patients. DESIGN: Cross-sectional study using patient-confirmed outpatient medication plans to describe PIMs and PPOs using the 'Screening Tool of Older Person's Prescription/Screening Tool to Alert to Right Treatment' version 2. Four Poisson regressions modelled the number of PIMs and PPOs using context-adapted versions of the Usual Provider of Care (UPC) and the Modified Modified Continuity Index (MMCI) as measures for CoC. SETTING: Southern Germany, outpatient setting. PARTICIPANTS: 321 participants of the LoChro-trial at 12-month follow-up (both arms). The LoChro-trial compared healthcare involving an additional care manager with usual care. Inclusion criteria were age over 64, local residence and scoring over one in the Identification of Older patients at Risk Screening Tool. PRIMARY OUTCOMES: Numbers of PIMs and PPOs. RESULTS: The mean number of PIMs was 1.5 (SD 1.5), lower than the average number of PPOs at 2.9 (SD 1.7). CoC showed similar results for both indices with a mean of 0.548 (SD 0.279) for MMCI and 0.514 (SD 0.262) for UPC. Both models predicting PPOs indicated more PPOs with higher CoC; statistical significance was only demonstrated for MMCI (MMCI~PPO: Exp(B)=1.42, 95% CI (1.11; 1.81), p=0.004; UPC~PPO: Exp(B)=1.29, 95% CI (0.99; 1.67), p=0.056). No significant association between PIMs and CoC was found (MMCI~PIM: Exp(B)=0.72, 95% CI (0.50; 1.03), p=0.072; UPC~PIM: Exp(B)=0.83, 95% CI (0.57; 1.21), p=0.337). CONCLUSION: The results did not show a significant association between higher CoC and lesser PIMs. Remarkably, an association between increased CoC, represented through MMCI, and more PPOs was found. Consultation of different care providers in open-access healthcare systems could possibly ameliorate under-prescribing in multimorbid older patients.
