  abstract  = {Patienten mit Lungenkarzinom sind bzgl. Malnutrition besonders gef{\"a}hrdet. Zu-dem wird dieses Problem selten fr{\"u}h genug erkannt und ad{\"a}quat therapiert, obwohl es weit verbreitet ist. Es gibt Untersuchungen, die Ern{\"a}hrung und Er-n{\"a}hrungszustand bei Patenten mit Lungenkarzinom untersuchen, wobei die Forderung nach weiteren Studien besteht. Dementsprechend wurden in der vorliegenden Studie folgende Fragestellungen formuliert: 1. Wie ist der Verlauf von BMI und Phasenwinkel bei Patienten mit Lungen-karzinom? Gibt es hier Unterschiede bei OP oder Bestrahlung sowie uni- oder multimodaler Therapie? 2. Wie ist der Verlauf von Fatigue, Schmerz, Dysphagie und w{\"o}chentlichem Verzehr von Quark oder H{\"u}ttenk{\"a}se sowie regelm{\"a}ßiger Mahlzeiten und der Einnahme von Trinknahrung? 3. Gibt es Zusammenh{\"a}nge zwischen BMI und Phasenwinkel als Indikator des Ern{\"a}hrungszustands sowie Beschwerden und Ern{\"a}hrung? In der vorliegenden Untersuchung wurden 83 station{\"a}re Patienten mit neu dia-gnostiziertem oder rezidiviertem Lungenkarzinom an der Missions{\"a}rztlichen Klinik W{\"u}rzburg untersucht. 64 Patienten wurden prospektiv und 19 retrospektiv f{\"u}r einen Zeitraum von 6 Monaten betrachtet. Schwerpunkte der Untersuchung waren Ern{\"a}hrungszustand, Symptomlast und Ern{\"a}hrung der Patienten. S{\"a}mtli-che Patienten hatten sich mindestens einer Form von antitumoraler Therapie bestehend aus Chemotherapie, Bestrahlung oder Operation sowie einer Ern{\"a}h-rungsberatung durch eine {\"O}kotrophologin unterzogen. Das Kollektiv wurde in die Gruppen 1 bis 3 eingeteilt. Gruppe 1 (N = 19) wurde r{\"u}ckblickend, Gruppe 2 (N = 23) und 3 (N = 41) prospektiv betrachtet. Gruppe 3 wurde gebildet, um jene Patienten der Datenerhebung abzubilden, bei denen teilweise unvollst{\"a}ndige Daten vorlagen. Nur Gruppe 2 und 3 wurden mit Fra-geb{\"o}gen zu Monat 1, 3 und 6 befragt. Diese B{\"o}gen bestanden aus dem Frage-bogen QLQ-C30 (Version 3.0) nach EORTC (European Organisation for Re-search and Treatment of Cancer) und einem selbst entworfenen Fragebogen mit Fokus auf {\"O}kotrophologie bei Krebserkrankungen. Aus ersterem Fragebo-gen wurden nur die Symptome Fatigue und Schmerz in der Auswertung unter-sucht. Aus letzterem Fragebogen wurden lediglich das Symptom Dysphagie und die Fragen nach dem w{\"o}chentlichen Konsum von Quark oder H{\"u}ttenk{\"a}se, der Einnahme regelm{\"a}ßiger Mahlzeiten und der Einnahme von Zusatznahrung in der Auswertung n{\"a}her betrachtet. Bei Betrachtung von BMI und Phasenwinkel wurde jeweils ein signifikanter (p < 0,05), schwacher Abfall festgestellt. Die Ver{\"a}nderungen des BMI nach Be-strahlung oder OP bzw. ohne die jeweilige Behandlung waren nicht signifikant. Ebenso konnten keine signifikanten Ver{\"a}nderungen f{\"u}r den Verlauf des BMI unter uni- oder multimodaler Therapie gefunden werden. F{\"u}r den Verlauf von Fatigue, Schmerz, Dysphagie und w{\"o}chentlichem Verzehr von Quark oder H{\"u}t-tenk{\"a}se wurden keine signifikanten Ver{\"a}nderungen festgestellt. Zudem waren die Angaben zu den Ver{\"a}nderungen regelm{\"a}ßig eingenommener Mahlzeiten und der Einnahme von Zusatznahrung nicht signifikant. Eine Testung auf Signi-fikanz f{\"u}r die Werte im Zusammenhang mit dem Phasenwinkel war aufgrund kleiner Fallzahlen nicht sinnvoll. F{\"u}r die Korrelation zwischen dem Verlauf des BMI und Dysphagie, Schmerz, Fatigue und w{\"o}chentlichem Verzehr von Quark oder H{\"u}ttenk{\"a}se konnte nur ein Trend festgestellt werden. Eine Korrelation des Phasenwinkels konnte wegen kleiner Fallzahlen nicht durchgef{\"u}hrt werden. Zwischen dem Verlauf von Fati-gue, Schmerz, Dysphagie und w{\"o}chentlichem Verzehr von Quark oder H{\"u}tten-k{\"a}se fanden sich zum Teil signifikante Korrelationen. Weitere Untersuchungen mit ausreichend großer Fallzahl sind n{\"o}tig, um die Datenlage der Malnutrition bei Patienten mit Lungenkarzinom in Deutschland zu verbessern. In der klinischen Praxis sollte Ern{\"a}hrung und Ern{\"a}hrungszustand mehr Beachtung geschenkt werden. Diese Befunde geben Hinweise darauf, dass Patienten mit Lungenkarzinom eine Verschlechterung des Ern{\"a}hrungszustands erleiden und dass Ern{\"a}hrung und Symptome miteinander zusammenh{\"a}ngen k{\"o}nnen.},

  abstract  = {Background Genital human papillomavirus (HPV)-infections are common in the general population and are responsible for relevant numbers of epithelial malignancies. Much data on the HPV-prevalence is available for secondary immunodeficiencies, especially for patients with human immunodeficiency virus (HIV)-infection. Little is known about the genital HPV-prevalence in patients with primary immunodeficiencies (PIDs). Methods We performed a cross-sectional study of patients with PIDs and took genital swabs from male and female patients, which were analyzed with polymerase chain reaction for the presence of HPV-DNA. Clinical and laboratory data was collected to identify risk factors. Results 28 PID patients were included in this study. 10 of 28 (35.7\%) had HPV-DNA in their genital swabs. 6 patients had high-risk HPV-types (21.4\%). Most patients had asymptomatic HPV-infections, as genital warts were rare (2 of 28 patients) and HPV-associated malignancy was absent. Differences in the HPV-positivity regarding clinical PID-diagnosis, duration of PID, age, sex, immunosuppression, immunoglobulin replacement, or circumcision in males were not present. HPV-positive PID patients had higher numbers of T cells (CD3\(^+\)), of cytotoxic T cells (CD3\(^+\)/CD8\(^+\)), of transitional B cells (CD19\(^+\)/CD38\(^{++}\)/CD10\(^+\)/IgD\(^+\)), and of plasmablasts (CD19\(^+\)/CD38\(^+\)/CD27\(^{++}\)/IgD\(^-\)) compared to HPV-negative. Conclusion PID patients exhibit a high rate of genital HPV-infections with a high rate of high-risk HPV-types. Regular screening for symptomatic genital HPV-infection and HPV-associated malignancy in PID patients seems recommendable.},

  abstract  = {Background Current research in breast cancer focuses on individualization of local and systemic therapies with adequate escalation or de-escalation strategies. As a result, about two-thirds of breast cancer patients can be cured, but up to one-third eventually develop metastatic disease, which is considered incurable with currently available treatment options. This underscores the importance to develop a metastatic recurrence score to escalate or de-escalate treatment strategies. Patients and methods Data from 10,499 patients were available from 17 clinical cancer registries (BRENDA-project. In total, 8566 were used to develop the BRENDA-Index. This index was calculated from the regression coefficients of a Cox regression model for metastasis-free survival (MFS). Based on this index, patients were categorized into very high, high, intermediate, low, and very low risk groups forming the BRENDA-Score. Bootstrapping was used for internal validation and an independent dataset of 1883 patients for external validation. The predictive accuracy was checked by Harrell's c-index. In addition, the BRENDA-Score was analyzed as a marker for overall survival (OS) and compared to the Nottingham prognostic score (NPS). Results: Intrinsic subtypes, tumour size, grading, and nodal status were identified as statistically significant prognostic factors in the multivariate analysis. The five prognostic groups of the BRENDA-Score showed highly significant (p < 0.001) differences regarding MFS:low risk: hazard ratio (HR) = 2.4, 95\%CI (1.7-3.3); intermediate risk: HR = 5.0, 95\%CI.(3.6-6.9); high risk: HR = 10.3, 95\%CI (7.4-14.3) and very high risk: HR = 18.1, 95\%CI (13.2-24.9). The external validation showed congruent results. A multivariate Cox regression model for OS with BRENDA-Score and NPS as covariates showed that of these two scores only the BRENDA-Score is significant (BRENDA-Score p < 0.001; NPS p = 0.447). Therefore, the BRENDA-Score is also a good prognostic marker for OS. Conclusion: The BRENDA-Score is an internally and externally validated robust predictive tool for metastatic recurrence in breast cancer patients. It is based on routine parameters easily accessible in daily clinical care. In addition, the BRENDA-Score is a good prognostic marker for overall survival. Highlights: The BRENDA-Score is a highly significant predictive tool for metastatic recurrence of breast cancer patients. The BRENDA-Score is stable for at least the first five years after primary diagnosis, i.e., the sensitivities and specificities of this predicting system is rather similar to the NPI with AUCs between 0.76 and 0.81 the BRENDA-Score is a good prognostic marker for overall survival.},

  abstract  = {Background Pelvic palpation is a core component of every Gynecologic examination. It requires vigorous training, which is difficult due to its intimate nature, leading to a need of simulation. Up until now, there are mainly models available for mere palpation which do not offer adequate visualization of the concerning anatomical structures. In this study we present a 3D printed model of the female pelvis. It can improve both the practical teaching of gynecological pelvic examination for health care professionals and the spatial understanding of the relevant anatomy. Methods We developed a virtual, simplified model showing selected parts of the female pelvis. 3D printing was used to create a physical model. Results The life-size 3D printed model has the ability of being physically assembled step by step by its users. Consequently, it improves teaching especially when combining it with commercial phantoms, which are built solely for palpation training. This is achieved by correlating haptic and visual sensations with the resulting feedback received. Conclusion The presented 3D printed model of the female pelvis can be of aid for visualizing and teaching pelvic anatomy and examination to medical staff. 3D printing provides the possibility of creating, multiplying, adapting and sharing such data worldwide with little investment of resources. Thus, an important contribution to the international medical community can be made for training this challenging examination.},

  abstract  = {Background Electrosurgical excisions are common procedures for treating cervical dysplasia and are often seen as minor surgeries. Yet, thorough training of this intervention is required, as there are considerable consequences of inadequate resections, e.g. preterm birth, the risk of recurrence, injuries and many more. Unfortunately, there is a lack of sufficiently validated possibilities of simulating electrosurgeries, which focus on high fidelity and patient safety. Methods A novel 3D printed simulator for examination and electrosurgical treatment of dysplastic areas of the cervix was compared with a conventional simulator. Sixty medical students experienced a seminar about cervical dysplasia. Group A underwent the seminar with the conventional and Group B with the novel simulator. After a theoretical introduction, the students were randomly assigned by picking a ticket from a box and went on to perform the hands-on training with their respective simulator. Each student first obtained colposcopic examination training. Then he or she performed five electrosurgical excisions (each). This was assessed with a validated score, to visualize their learning curve. Furthermore, adequate and inadequate resections and contacts between electrosurgical loop and vagina or speculum were counted. Both groups also assessed the seminar and their simulator with 18 questions (Likert-scales, 1-10, 1 = strongly agree / very good, 10 = strongly disagree / very bad). Group B additionally assessed the novel simulator with four questions (similar Likert-scales, 1-10). Results Nine of 18 questions showed statistically significant differences favoring Group B (p < 0.05). Group B also achieved more adequate R0-resections and less contacts between electrosurgical loop and vagina or speculum. The learning curves of the performed resections favored the novel simulator of Group B without statistically significant differences. The four questions focusing on certain aspects of the novel simulator indicate high appreciation of the students with a mean score of 1.6 points. Conclusion The presented novel simulator shows several advantages compared to the existing model. Thus, novice gynecologists can be supported with a higher quality of simulation to improve their training and thereby patient safety.},

  abstract  = {Background Simulation in the field of gynecological pelvic examination with educational purposes holds great potential. In the current manuscript we evaluate a 3D printed model of the female pelvis, which improves practical teaching of the gynecological pelvic examination for medical staff. Methods We evaluated the benefit of a 3D printed model of the female pelvis (Pelvisio®) as part of a seminar ("skills training") for teaching gynecological examination to medical students. Each student was randomly assigned to Group A or B by picking a ticket from a box. Group A underwent the skills training without the 3D printed model. Group B experienced the same seminar with integration of the model. Both groups evaluated the seminar by answering five questions on Likert scales (1-10, 1 = "very little" or "very poor", 10 equals "very much" or "very good"). Additionally, both groups answered three multiple-choice questions concerning pelvic anatomy (Question 6 to 8). Finally, Group B evaluated the 3D printed model with ten questions (Question 9 to 18, Likert scales, 1-10). Results Two of five questions concerning the students' satisfaction with the seminar and their gained knowledge showed statistically significant better ratings in Group B (6.7 vs. 8.2 points and 8.1 vs. 8.9 points (p < 0.001 and p < 0.009). The other three questions showed no statistically significant differences between the traditional teaching setting vs. the 3D printed model (p < 0.411, p < 0.344 and p < 0.215, respectively). The overall mean score of Question 1 to 5 showed 8.4 points for Group B and 7.8 points for Group A (p < 0.001). All three multiple-choice questions, asking about female pelvic anatomy, were answered more often correctly by Group B (p < 0.001, p < 0.008 and p < 0.001, respectively). The mean score from the answers to Questions 9 to 18, only answered by Group B, showed a mean of 8.6 points, indicating, that the students approved of the model. Conclusion The presented 3D printed model Pelvisio® improves the education of female pelvic anatomy and examination for medical students. Hence, training this pivotal examination can be supported by a custom designed anatomical model tailored for interactive and explorative learning.},

  abstract  = {Brain metastases are the most severe tumorous spread during breast cancer disease. They are associated with a limited quality of life and a very poor overall survival. A subtype of extracellular vesicles, exosomes, are sequestered by all kinds of cells, including tumor cells, and play a role in cell-cell communication. Exosomes contain, among others, microRNAs (miRs). Exosomes can be taken up by other cells in the body, and their active molecules can affect the cellular process in target cells. Tumor-secreted exosomes can affect the integrity of the blood-brain barrier (BBB) and have an impact on brain metastases forming. Serum samples from healthy donors, breast cancer patients with primary tumors, or with brain, bone, or visceral metastases were used to isolate exosomes and exosomal miRs. Exosomes expressed exosomal markers CD63 and CD9, and their amount did not vary significantly between groups, as shown by Western blot and ELISA. The selected 48 miRs were detected using real-time PCR. Area under the receiver-operating characteristic curve (AUC) was used to evaluate the diagnostic accuracy. We identified two miRs with the potential to serve as prognostic markers for brain metastases. Hsa-miR-576-3p was significantly upregulated, and hsa-miR-130a-3p was significantly downregulated in exosomes from breast cancer patients with cerebral metastases with AUC: 0.705 and 0.699, respectively. Furthermore, correlation of miR levels with tumor markers revealed that hsa-miR-340-5p levels were significantly correlated with the percentage of Ki67-positive tumor cells, while hsa-miR-342-3p levels were inversely correlated with tumor staging. Analysis of the expression levels of miRs in serum exosomes from breast cancer patients has the potential to identify new, non-invasive, blood-borne prognostic molecular markers to predict the potential for brain metastasis in breast cancer. Additional functional analyzes and careful validation of the identified markers are required before their potential future diagnostic use.},

  abstract  = {Purpose The reliable detection of tumor-infiltrated axillary lymph nodes for breast cancer [BC] patients plays a decisive role in further therapy. We aimed to find out whether cross-sectional imaging techniques could improve sensitivity for pretherapeutic axillary staging in nodal-positive BC patients compared to conventional imaging such as mammography and sonography. Methods Data for breast cancer patients with tumor-infiltrated axillary lymph nodes having received surgery between 2014 and 2020 were included in this study. All examinations (sonography, mammography, computed tomography [CT] and magnetic resonance imaging [MRI]) were interpreted by board-certified specialists in radiology. The sensitivity of different imaging modalities was calculated, and binary logistic regression analyses were performed to detect variables influencing the detection of positive lymph nodes. Results All included 382 breast cancer patients had received conventional imaging, while 52.61\% of the patients had received cross-sectional imaging. The sensitivity of the combination of all imaging modalities was 68.89\%. The combination of MRI and CT showed 63.83\% and the combination of sonography and mammography showed 36.11\% sensitivity. Conclusion We could demonstrate that cross-sectional imaging can improve the sensitivity of the detection of tumor-infiltrated axillary lymph nodes in breast cancer patients. Only the safe detection of these lymph nodes at the time of diagnosis enables the evaluation of the response to neoadjuvant therapy, thereby allowing access to prognosis and improving new post-neoadjuvant therapies.},

  abstract  = {Purpose Therapeutic options for breast cancer (BC) treatment are constantly evolving. The Human Epidermal Growth Factor 2 (HER2)-low BC entity is a new subgroup, representing about 55\% of all BC patients. New antibody-drug conjugates demonstrated promising results for this BC subgroup. Currently, there is limited information about the conversion of HER2 subtypes between primary tumor and recurrent disease. Methods This retrospective study included women with BC at the University Medical Centre Wuerzburg from 1998 to 2021. Data were retrieved from patients' records. HER2 evolution from primary diagnosis to the first relapse and the development of secondary metastases was investigated. Results In the HR-positive subgroup without HER2 overexpression, HER2-low expression in primary BC was 56.7 vs. 14.6\% in the triple-negative subgroup (p < 0.000). In the cohort of the first relapse, HER2-low represented 64.1\% of HR-positive vs. 48.2\% of the triple-negative cohort (p = 0.03). In patients with secondary metastases, HER2-low was 75.6\% vs. 50\% in the triple negative subgroup (p = 0.10). The subgroup of HER2-positive breast cancer patients numerically increased in the course of disease; the HER2-negative overall cohort decreased. A loss of HER2 expression from primary BC to the first relapse correlated with a better OS (p = 0.018). No clinicopathological or therapeutic features could be identified as potential risk factors for HER2 conversion. Conclusion HER2 expression is rising during the progression of BC disease. In view of upcoming therapeutical options, the re-analysis of newly developed metastasis will become increasingly important.},

By receiving treatment at a certified breast cancer center, the patient has the best chance of treatment in accordance with guidelines and the best prognosis. The identification of risk factors for a delay of therapy is of central importance and should be the basis for a continuous optimization of treatment at breast cancer centers. Methods This retrospective study included women with breast cancer (primary diagnosis, relapse, or secondary malignancy) at the University Hospital W{\"u}rzburg in 2019 and 2020. Data were retrieved from patients' records. Correlations and regression analyses were performed to detect potential risk factors for treatment delay. Results Patients who received the histological confirmation of breast cancer at an external institution experienced a later therapy start than those patients who received the histological confirmation at the University Hospital W{\"u}rzburg itself. (35.7 vs. 32.2 days). The interval between histological confirmation and the first consultation at the University Hospital W{\"u}rzburg correlated statistically significant with age, distress and distance to the hospital. Conclusion Patients with an in-house diagnosis of breast cancer are treated more quickly than those whose diagnosis was confirmed in an external institution. We identified factors such as increased age, greater distance to the hospital as well as increased distress to prolong the time until start of oncological treatment. Intensified patient care should be offered to these subgroups.},
