First effectiveness data of lenvatinib and pembrolizumab as first-line therapy in advanced anaplastic thyroid cancer: a retrospective cohort study.

BACKGROUND: Anaplastic thyroid cancer (ATC) is a rare and aggressive neoplasm. We still lack effective treatment options, so survival rates remain very low. Here, we aimed to evaluate the activity of the combination of lenvatinib and pembrolizumab as systemic first-line therapy in ATC. METHODS: In a retrospective analysis, we investigated the activity and tolerability of combined lenvatinib (starting dose 14 to 24 mg daily) and pembrolizumab (200 mg every three weeks) as first-line therapy in an institutional cohort of ATC patients. RESULTS: Five patients with metastatic ATC received lenvatinib and pembrolizumab as systemic first-line therapy. The median progression-free survival was 4.7 (range 0.8-5.9) months, and the median overall survival was 6.3 (range 0.8-not reached) months. At the first follow-up, one patient had partial response, three patients had stable disease, and one patient was formally not evaluable due to interference of assessment by concomitant acute infectious thyroiditis. This patient was then stable for more than one year and was still on therapy at the data cutoff without disease progression. Further analyses revealed deficient DNA mismatch repair, high CD8+ lymphocyte infiltration, and low macrophage infiltration in this patient. Of the other patients, two had progressive disease after adverse drug reactions and therapy de-escalation, and two died after the first staging. For all patients, the PD-L1 combined positive score ranged from 12 to 100%. CONCLUSIONS: The combination of lenvatinib and pembrolizumab was effective and moderately tolerated in treatment-naïve ATC patients with occasional long-lasting response. However, we could not confirm the exceptional responses for this combination therapy reported before in pretreated patients.

Work and Training Conditions of German Residents and Young Radiologists in Interventional Radiology - A Nationwide Survey.

With the increasing need for minimally invasive procedures based on lower complication rates, higher patient acceptance, and technical developments, there is a growing focus on the sound interventional training of young radiologists. This survey aimed to analyze the current situation in interventional radiology (IR) training in Germany to detect shortcomings and identify areas for improvement.From November 1-30, 2020, an online questionnaire was distributed to representative radiological associations and societies with the request to forward it to radiology residents and radiologists < 40 years. The 44 questions covered six distinct areas from personal working conditions to the characterization of the IR department, training conditions, role of women in IR, and attendance at congresses/external training.A total of 330 participants completed the questionnaire. 77 % of participants expressed a high interest in IR, and 47 % could even imagine subspecializing in interventional radiology. Most institutions provided the necessary learning conditions and infrastructure. The rate of overall satisfaction with IR training conditions was 45 % (vs. a dissatisfaction rate of 39 %). However, females showed a lower satisfaction rate with their training environment than male participants (28 % vs. 51 %; P = 0.06). Positive correlations with work satisfaction were found for the presence and duration of the IR rotation, the number of partly independently/mentored performed interventions, and structured feedback. Moreover, the need for a structured training curriculum was expressed by 67 % of participants.Radiological residents and young radiologists expressed a high interest in interventional radiology, and they rate the infrastructure of German hospitals regarding IR as sufficient. However, they expressed the need for consistent IR rotations and better-structured resident and postgraduate education (curricula & interviews).Interest in interventional radiology among radiological residents and young radiologists in Germany is high, but satisfaction with interventional radiology training leaves room for improvement. The most frequently mentioned aspects that can improve IR training were · organized rotations of at least 6 months. · structured curriculums with face-to-face feedback. · structured guidance by senior interventionists during procedures.

Short- and long-term evaluation of disease-specific symptoms and quality of life following uterine artery embolization of fibroids.

BACKGROUND: The purpose of this study is to evaluate uterine artery embolization (UAE) for the management of symptomatic uterine leiomyomas regarding changes in quality of life after treatment in a large patient collective. This study retrospectively analyzed prospectively acquired standardized questionnaires of patients treated with UAE. Clinical success was evaluated before and after embolization. Patients were stratified into short- (≤ 7 months) and long-term (> 7 months) follow-up groups depending on the time of completion of the post-interventional questionnaire. Uterine leiomyomas were furthermore divided into small (< 10 cm) and large (≥ 10 cm) tumors based on the diameter of the dominant fibroid. RESULTS: A total of 245 patients were included into the final data analysis. The Kaplan-Meier analysis showed a cumulative clinical success rate of 75.8% after 70 months until the end of follow-up (9.9 years). All questionnaire subscales showed a highly significant clinical improvement from baseline to short- and long-term follow-up (p < 0.001). Patients with small fibroids showed a significantly better response to UAE in multiple subcategories of the questionnaire than patients with fibroids ≥ 10 cm who had a twofold higher probability of re-intervention in the Cox-regression model. CONCLUSIONS: UAE is an effective treatment method for symptomatic fibroids that leads to quick relief of fibroid-related symptoms with marked improvement of quality of life and is associated with a low risk for re-interventions. Patients with small fibroids tend to show a better response to UAE compared to patients with large fibroids. Trial registration Charité institutional review board, EA4/167/20.

CT fluoroscopy-guided percutaneous gastrostomy (CT-PG) - A single center experience in 233 patients.

PURPOSE: To investigate the feasibility and complications of computed tomography-guided percutaneous gastroscopy (CT-PG) using two procedural techniques (trocar technique and Seldinger technique) in all patients and in a subgroup of patients with ascites as a relative contraindication. MATERIAL AND METHODS: In this single-center study a total of 233 patients who underwent CT-PG (55 in trocar group and 178 in Seldinger group) between 2012 and 2021 were analyzed retrospectively. Success and complications were determined for both techniques and compared in the total study population and in the subgroup of patients with ascites. Complications were classified using the Common Terminology Criteria for Adverse Events (CTCAE) Protocol for procedural complications. RESULTS: Feeding tube placement was successful in 93.6% of cases (218/233). In the trocar group, placement was successful in 98.2% (54/55) with a complication rate of 7.4% (4/54) including one grade 5 complication. In the Seldinger group, placement was successful in 92.1% (164/178) with a complication rate of 6.7% but no grade 4 or 5 complication. Preprocedural paracentesis for ascites was performed in 6.9% of patients (16/233). In this subgroup, CT-PG was successful in 87.5% (14/16) and only complications rated as grade 1 or 2 occurred. CONCLUSION: CT-PG is a safe interventional procedure, which also applies to patients with ascites if paracentesis is performed beforehand. Specifically, our findings show the Seldinger technique to be safe, as no severe complications occurred in this subgroup.

A prospective randomized controlled trial assessing the effect of music on patients' anxiety in venous catheter placement procedures.

The aim of the study was to assess the influence of music on anxiety levels compared to standard patient care in patients undergoing venous catheter placement procedures. This prospective randomized controlled trial included patients undergoing placement procedures for peripherally inserted central venous catheters (PICC), ports and central venous catheters (CVC). Patients were randomly assigned to a music intervention group (MIG) and a control group (CTRL). State and trait anxiety levels were assessed as primary outcome using the state-trait anxiety inventory (STAI) before and after the procedures. Secondary outcomes comprised averaged heart rate for all participants and time of radiological surveillance for port placement procedures exclusively. 72 participants were included into the final analysis (MIG n = 40; CTRL n = 32). All procedures were successful and no major complications were reported. Mean levels for post-interventional anxieties were significantly lower in the MIG compared to the CTRL (34.9 ± 8.9 vs. 44 ± 12.1; p < 0.001). Mean heart rate in the MIG was significantly lower than in the CTRL (76.1 ± 13.7 vs. 93 ± 8.9; p < 0.001). Procedure time for port implantation was significantly longer in the MIG by 3 min 45 s (p = 0.031). Music exposure during central venous catheter placement procedures highly significantly reduces anxiety and stress levels and can be used to improve patients' overall experience in the angio suite.

CoRad-19 - Modular Digital Teaching during the SARS-CoV-2 Pandemic. / CoRad-19 ­ Modulare Digitale Lehre während der SARS-CoV-2-Pandemie.

PURPOSE: During the SARS-CoV-2 pandemic, higher education worldwide had to switch to digital formats. The purpose of this study was to evaluate CoRad-19, a digital teaching tool created by the German Radiological Society for medical students during the COVID-19 pandemic. MATERIALS AND METHODS: A total of 13 German-speaking universities implemented CoRad-19 in their curriculum and partially or completely replaced their classes with the online courses. Previous experience and contact with radiology and the participants' opinions regarding the medium of e-learning were surveyed using a custom questionnaire. The subjective level of knowledge regarding the individual modules was also surveyed before and after participation to measure learning effects. The data of 994 medical students from the participating sites were analyzed and compared intraindividually using the Friedman test. RESULTS: From 4/1/2020-10/1/2020, 451 complete data sets from a total of 994 surveys were included. E-learning was rated "very useful" both before and after course participation (4 [IQR 3-4], p = 0.527, r = 0.16). E-learning as a method was also rated as a "very good" medium both before and after participation (4 [IQR 3-4], p = 0.414, r = 0.17). After participation, participants rated radiology as particularly suitable for digital teaching (before: 3 [IQR 3-4] vs. after 4 [IQR 3-4], p = 0.005, r = 0.6). Significant learning gains were measurable in all course modules (p ≤ 0.009). Post-hoc analysis showed interest in radiology to increase significantly after course participation (p = 0.02). CONCLUSION: In the representative survey, significant learning effects were observed in all course modules. In addition, it should be particularly emphasized that the students' interest in radiology was increased by course participation. Thus, the German Radiological Society provided significant support to German-speaking medical faculties with respect to maintaining excellent education using CoRad-19. KEY POINT: · Co-Rad-19 course participation results in measurable subjective learning effects and increases student interest in radiology..

Apelin Controls Angiogenesis-Dependent Glioblastoma Growth.

Glioblastoma (GBM) present with an abundant and aberrant tumor neo-vasculature. While rapid growth of solid tumors depends on the initiation of tumor angiogenesis, GBM also progress by infiltrative growth and vascular co-option. The angiogenic factor apelin (APLN) and its receptor (APLNR) are upregulated in GBM patient samples as compared to normal brain tissue. Here, we studied the role of apelin/APLNR signaling in GBM angiogenesis and growth. By functional analysis of apelin in orthotopic GBM mouse models, we found that apelin/APLNR signaling is required for in vivo tumor angiogenesis. Knockdown of tumor cell-derived APLN massively reduced the tumor vasculature. Additional loss of the apelin signal in endothelial tip cells using the APLN-knockout (KO) mouse led to a further reduction of GBM angiogenesis. Direct infusion of the bioactive peptide apelin-13 rescued the vascular loss-of-function phenotype specifically. In addition, APLN depletion massively reduced angiogenesis-dependent tumor growth. Consequently, survival of GBM-bearing mice was significantly increased when APLN expression was missing in the brain tumor microenvironment. Thus, we suggest that targeting vascular apelin may serve as an alternative strategy for anti-angiogenesis in GBM.

Performance survey on a new standardized formula for oral signal suppression in MRCP.

BACKGROUND: Orally administered substances, which reduce image contamination by overlying gastrointestinal fluid signals, can be used to enhance the quality of MRCP images. Recently, a new standardized formula consisting of biological substances has become available. The objective of this study is to provide a first assessment of achievable MRCP image quality, taste and palatability of this new dedicated agent. METHODS: In January 2015 to May 2015 practicing radiologists in Germany, Austria and Switzerland were asked to evaluate image quality as well as taste and palatability when using the new agent (LumiVision®; b.e. imaging; Baden-Baden; Germany) in MRCP questionnaire. Both criteria were rated with a 6-point Likert scale ranging from "1" (best) to "6" (worst). RESULTS: A total 185 of 475 radiologic institutions (39%) submitted feedback on image quality, 187 (39%) on the taste/palatability. Assessments of image quality regarding presence of disturbing gastrointestinal fluid signal resulted in a median of 2. The majority of patients rated the subjective taste as very good (median of 1). No side effects of relevance were recorded. CONCLUSION: This large survey shows that the tested product is considered effective by radiologists regarding MRCP image quality. Patients' feedback on taste and palatability was very positive.

Efficacy of oral contrast agents for upper gastrointestinal signal suppression in MRCP: A systematic review of the literature.

BACKGROUND: Orally administered substances which suppress signals from gastrointestinal fluid can be used to enhance image quality in magnetic resonance cholangiopancreatography (MRCP). In daily practice, the available substances range from commercial products to regular viands such as fruit juices. PURPOSE: To provide an overview on the significance of and the substances used as gastrointestinal fluid signal suppressors in MRCP. MATERIAL AND METHODS: A systematic review of the existing literature was performed to evaluate the efficacy and efficiency of oral T2-signal suppressors in MRCP. RESULTS: Twenty-five publications on 16 different oral contrast media were identified. The most commonly used substances were ferumoxsil, ferric ammonium citrate, and pineapple juice. Twenty-three out of 25 publications supported the use of oral signal suppressors in MRCP. Advantages of oral signal suppressors include improved visualization of the pancreatobiliary ductal system, increased help with differential diagnoses, and higher detection rates of relevant diagnoses due to a reduction of overlaying signals. CONCLUSION: The application of oral substances for gastrointestinal signal suppression in MRCP is recommendable. A variety of substances are used in daily routine with good but varying effectivity and patient tolerance.

Shoulder pain among high-level volleyball players and preseason features.

PURPOSE: The main goal of this prospective study was to identify the most significant intrinsic risk factors for shoulder pain by measuring strength developed by shoulder rotators and by carrying out various morphostatic assessments. METHODS: Sixty-six players (mean ± SD age = 24 ± 5 yr) were recruited from nine volleyball teams from the first and second divisions (34 men and 32 women) to participate in the study. Before the start of the volleyball season, all the participants completed a preseason questionnaire and underwent both a bilateral isokinetic evaluation of the shoulders and morphostatic measurements. During the subsequent 6 months of the competition period, the players reported through a weekly questionnaire any shoulder pain experienced. RESULTS: During the ongoing season, 23% (15 of 66 players) of the volleyball players experienced dominant shoulder pain. Interestingly, participants who reported a history of dominant shoulder pain were found to have nine times higher risk of suffering further pain in their dominant shoulder. The eccentric maximal strength developed by the internal and external rotators was found to represent a protective factor in the volleyball players (respective odds ratios = 0.946, P = 0.01 and 0.94, P = 0.05). No risk factors were found among the shoulder morphostatic measurements. CONCLUSION: In our study, the evaluation of shoulder rotator muscle strength through isokinetic assessment, especially eccentric mode, appeared to be the most contributing parameter to identify risk factors for shoulder pain. This evaluation should allow to better identify players at risk.

Monitoring of sport participation and injury risk in young athletes.

OBJECTIVES: Careful modulation of training characteristics in high-level sports optimizes performance and avoids inappropriate workloads and associated sports injury risk. The aims of this study were to compare sport participation characteristics in different youth sport categories and to investigate their relationship with injury. DESIGN: Prospective cohort follow-up. METHODS: Young (12-19 years) high-level athletes (n=154) from a regional sport school were followed during 41 weeks regarding sport participation characteristics and traumatic and overuse sports injuries (time-loss definition). All data were self-recorded by the athletes in an electronic system "TIPPS" (Training and Injury Prevention Platform for Sports) and subject to a systematic data quality control. Volume and intensity (self-rated perceived exertion) of each sport session were used to compute weekly load, monotony and strain. Sport categories were defined as team, racket, and individual sports. RESULTS: All sport participation characteristics were dependent on sport category (p<0.05). Weekly intensity, load and strain were dependent on age (p<0.05). Racket and individual sports were associated with lower injury risk (HR=0.37 and 0.34, p=0.001 and p<0.001, respectively) compared to team sports. Average sport participation characteristics were not related to injury according to the survival analysis. However, intensity during the week prior to injury was significantly higher (p<0.01) compared to that of the 4 preceding weeks. CONCLUSIONS: This study investigated for the first time the relationship between sport participation pattern and injury risk in young athletes. The monitoring method was sensitive to variations according to pertinent variables and might help identify athletes with increased sports injury risk.

Injury incidence in a sports school during a 3-year follow-up.

PURPOSE: This study prospectively analysed sports injury incidence over 3 seasons in a regional sports school within an injury surveillance project, involving 372 athletes (12-19 years) from 16 different disciplines. METHODS: A personal sports diary was used to record all sporting activities daily for every athlete. Injuries (time-loss definition) were registered via a standardized questionnaire. RESULTS: Sports injury incidence (injuries/1,000 h) evolved from 3.9 in the first year to 4.8 in the second (p < 0.01) and down to 2.8 in the third (p < 0.001, compared to the preceding periods). Significant decreases of injury incidence in the third year were also observed when classifying injuries as traumatic or overuse, and as new or recurrent. The proportion of recurrent injuries was lower in the third period (11 %) when compared to the first (19.5 %, p < 0.05) and the second one (26.3 %, p < 0.05). Injury incidence was lowest during the third period for all severity categories. The same was found when considering injuries within racket, team and individual sports. CONCLUSIONS: Implementing an injury surveillance system in this setting was associated with a lower injury incidence in the third observation period. This project may have influenced stakeholders' awareness and attitude towards the sports injury problematic.

Injury risk is different in team and individual youth sport.

OBJECTIVES: This study compared sports injury incidence in young high-level athletes from various team and individual sports and investigated if sport participation patterns are linked to injuries. DESIGN: Prospective cohort follow-up. METHODS: Pupils from a public sports school (12-19 years) were recruited over two separate school years (2008-2009: 42 weeks, n=199 athletes; 2009-2010: 40 weeks, n=89 athletes). Training and competition volume and intensity were recorded via a personal sports diary. Sports injuries (time-loss definition) were registered by medical staff members using a standardized questionnaire. RESULTS: Injury incidence was significantly higher in team compared with individual sports (6.16 versus 2.88 injuries/1000h, respectively), as a result of a higher incidence of both traumatic (RR=2.17; CI95%=1.75-2.70; p<0.001), and overuse injuries (RR=2.06; CI95%=1.46-2.91; p<0.001). A Cox proportional hazards regression revealed that team sports participation had a hazard ratio of 2.00 (CI95%=1.49-2.68; p<0.001) compared to individual sports, with additionally previous injury being a risk and age a protective factor. The number of competitions per 100 days was significantly higher in team sports, whereas the number of intense training sessions per 100 days was significantly lower. In team sports, the number of competitions per 100 days was positively associated with injuries (HR=1.072; CI95% [1.033; 1.113]; p<0.001), while in individual sports the number of competitions per 100 days had a protective effect (HR=0.940; CI95% [0.893; 0.989]; p=0.017). CONCLUSIONS: Team sports participation entailed a higher injury risk, whatever the injury category. Further research should elucidate the role of characteristics related to sport participation in injury causation.

The impact of presentation style on the retention of online health information: a randomized-controlled experiment.

The Internet plays an increasingly important role in health education, providing laypeople with information about health-related topics that range from disease-specific contexts to general health promotion. Compared to traditional health education, the Internet allows the use of multimedia applications that offer promise to enhance individuals' health knowledge and literacy. This study aims at testing the effect of multimedia presentation of health information on learning. Relying on an experimental design, it investigates how retention of information differs for text-only presentation, image-only presentation, and multimedia (text and image) presentation of online health information. Two hundred and forty students were randomly assigned to four groups each exposed to a different website version. Three groups were exposed to the same information using text only, image only, or text and image presentation. A fourth group received unrelated information (control group). Retention was assessed by the means of a recognition test. To examine a possible interaction between website version and recognition test, half of the students received a recognition test in text form and half of them received a recognition test in imagery form. In line with assumptions from Dual Coding Theory, students exposed to the multimedia (text and image) presentation recognized significantly more information than students exposed to the text-only presentation. This did not hold for students exposed to the image-only presentation. The impact of presentation style on retention scores was moderated by the way retention was assessed for image-only presentation, but not for text-only or multimedia presentation. Possible explanations and implications for the design of online health education interventions are discussed.

Defining and measuring health literacy: how can we profit from other literacy domains?

When the antecedents of health-promoting behavior are explored, the concept of health literacy is deemed a factor of major influence. Originally defined as reading, writing and numeracy skills in the health domain, health literacy is now considered a multidimensional concept. The ongoing discussion on health literacy reveals that no agreement exists about which dimensions to include in the concept. To contribute to the development of a consistent and parsimonious concept of health literacy, we conducted a critical review of concepts in other literacy domains. Our review was guided by two research questions: (i) Which dimensions are included in the concepts of other literacy domains? (ii) How can health literacy research profit from other literacy domains? Based on articles collected from PubMed, PsycINFO, Communication & Mass Media Complete, CINAHL, SAGE Full-Text Collection, Cochrane Library and Google Scholar as well as selected monographs and editions, we identified seven distinct dimensions. Some of the dimensions recur across all reviewed literacy domains and first attempts have been made to operationalize the dimensions. Expanding upon these dimensions, the paper discusses how they can prove useful for elaborating a consistent and parsimonious concept of health literacy and foster the development of a more holistic measure.

Injuries, risk factors and prevention initiatives in youth sport.

BACKGROUND: Sports injuries in young athletes are a public health issue which deserves special attention. Effective prevention can be achieved with training programmes originating from the field of physical therapy and medicine. SOURCES OF DATA: A systematic literature search on injury prevention in youth sport was performed in the MEDLINE database. AREAS OF AGREEMENT: For prevention programmes to reduce sports injuries, critical factors must be considered, such as training content, duration and frequency, as well as athlete compliance. AREAS OF CONTROVERSY: Home-based programmes could be inferior to supervised training, but are efficient if compliance is high. So far prevention programmes have focused on team sports and their efficiency in individual sports remains to be proven. GROWING POINTS: Active prevention programmes focusing specifically on the upper extremity are scarce. Initiatives enhancing the awareness of trainers, athletes and therapists about risk factors and systematic prevention measures should be encouraged.
