Are There Any Effective Behavior Change Strategies for Communicating Genetic Risk in Obesity Prevention and Body Weight Reduction Interventions?
This systematic review examined how differences in intervention components may contribute to inconsistent findings in genetic risk communication studies, addressing obesity-related outcomes (e.g., weight reduction, nutrition behavior, exercise). The review was preregistered (PROSPERO #CRD42024524026) and followed PRISMA guidelines. Searches across eight databases identified 23 randomized controlled trials, covering 18 intervention trials. Risk of bias was assessed using the Risk of Bias 2 tool. A narrative synthesis was used to cluster studies by the content of intervention and control groups. Genetic risk communication alone (no behavioral counseling, addressing nutrition and exercise) or combined with phenotype-based risk was ineffective and sometimes counterproductive among low-risk individuals. When combined with personalized behavioral counseling, effectiveness improved, but only when compared to waitlist control groups or non-personalized behavioral counseling. Significant effects emerged in high-genetic risk subgroups within personalized behavioral counseling, using behavior change techniques such as problem-solving, feedback on behavior, self-monitoring, and environmental changes. The most promising results emerged from complex interventions integrating genetic risk communication into multiple sessions and combining numerous additional behavioral change techniques, such as social reward, cues/prompts, self-reward. Complex personalized interventions combining multiple behavior change techniques and prompting experiential genetic risk awareness show promise for improving weight, nutrition, and exercise-related outcomes.

Objective assessment of the trauma patient in a surgical intensive care unit.
A 6-month study using the Therapeutic Intervention Scoring System (TISS) to evaluate trauma patients admitted to a surgical intensive care unit showed a correlation between severity of illness and TISS score at the same time. The TISS is useful in the ICU, where numerous complex interventions are made in caring for acutely ill and injured patients.

[Duodenopancreatic lesions in abdominal injuries. Clinical and therapeutic considerations].
The frequency of duodeno-pancreatic lesions in abdominal or thoraco-abdominal trauma hospitalized in the surgery clinic of the Emergency Hospital from Bucharest between 1960 and 1975 was of 0.57%. In the present study are stressed the important factors which influence the outcome of the interventions (age, the interval from the accident to hospitalization and that from hospitalization to surgery). The causes are described, that have generated abdominal trauma with duodeno-pancreatic lesions the intensity and the extension, the localization of the lesions, as well as the importance of the association with lesions of other organs. An analysis is made of the interventions that have been made, in which the type of duodeno-pancreatic lesion was taken into account, as well as the variety of the procedure applied, from the simple draining of the pancreatic lodge, and of the peritoneal cavity, to complex interventions including exeresis of the duodenum or of the pancreas. To conclude the authors show that duodeno-pancreatic lesions are of considerable severity and are one of the causes of high mortality. These lesions also represent a serious test for the surgeon when one has to make a decision on the technique to be performed during the intervention. These lesions are also very demanding from the viewpoint of the surgeon's technical capability.

Perspectives of participating neurologists and study nurses - Mixed-methods process evaluation of a web-based program for relapse management in multiple sclerosis (POWER@M2).
BACKGROUND: Relapsing-remitting multiple sclerosis is a chronic inflammatory disease of the central nervous system and the leading cause of disability in young adults. In Germany, 90% of relapses are treated with high-dose intravenous glucocorticoids, despite limited evidence for long-term benefit and international preference for oral administration. Time constraints often hinder informed decision-making. The multicentre Randomized Controlled Trial (RCT) POWER@MS2 (N = 160, 2020-2023), conducted at 18 German MS-centres, aimed to promote self-determined relapse management through a complex intervention (dialogue-based decision aid, nurse-led webinar, online-chat). OBJECTIVE: While RCTs demonstrate effectiveness, process evaluations are essential to understand implementation, mechanisms of impact and contextual factors. This study explored healthcare professionals' experiences and attitudes toward implementing relapse self-management and self-medication in clinical practice. METHODS: A mixed-methods process evaluation followed the UK Medical Research Council- framework. Quantitative data were collected via validated questionnaires at up to three time points and analysed descriptively. Interview guides were developed based on these results. Qualitative data from neurologist and study nurse interviews were thematically analysed. Results were triangulated using a joint display. RESULTS: Data were collected from 55 neurologists and 17 study nurses (quantitative) and from 7 neurologists and 4 nurses (qualitative) (2020-2024). Most neurologists opposed routine steroid use, reserving it for severe relapses. Some voiced concerns about self-management, but informed patients were generally viewed as capable of safe self-medication. Study nurses gave mixed feedback on the intervention, citing overload and improved guidance. CONCLUSION: Clinicians showed openness toward implementing the intervention. Enhancing accessibility and addressing specific concerns may support broader adoption.

[Fatal complications following the implantation of artificial lense (author's transl)].
The number of cataract operations with implantation of artificial lenses has been increasing in recent years. However, there is hardly any information available concerning possible serious consequences. While there are detailed reports on histopathological findings following conventional cataract operations, fatal complications of this technically complex intervention are only mentioned occasionally. There were 9 cases with serious complications in our polyclinic in 1976, and this report deals with the histopathological findings in 6 enucleated eyes. The authors warn against ill-considered decisions to perform a lens implantation.

[Hepato-biliary-pancreatic lesions in secondary duodenostasis].
The secondary postoperative duodenal stasis (afferent loop syndrome, chronic vicious circle) is underlain by evacuational disturbance of the duodenum. The duodenal stasis and hypertension lead to the stasis of the bile and pancreatic-secretion, which in turn results in inflammatory-dystrophic changes in the hepato-biliary-pancreatic system. In such cases the success of surgical treatment will derive from the application of complex intervention both on the digestive tract and hepato-biliary system.

Use of changes in the epicardial QRS complex to assess interventions which modify the extent of myocardial necrosis following coronary artery occlusion.
The goal of this study was to determine if changes in the epicardial QRS complex after coronary artery occlusion (CAO) can be used to evaluate the efficacy of interventions designed to limit infarct size. Forty-one open-chest dogs with CAO were studied: 15 were controls, 18 received hyaluronidase and eight received propranolol starting 20 minutes after CAO. Epicardial ECGs were recorded at specific time intervals to analyze ST-segment elevation and changes in Q and R waves. Transmural specimens were obtained 24 hours after CAO from the same sites at which ECGs were recorded. Q wave development (deltaQ), R wave fall (deltaR), and their combination (deltaR + deltaQ) at 24 hours correlated with the extent of necrosis, as determined by myocardial creatine phosphokinase activity depression and histologic appearance. In the control group ST-segment elevation 15 minutes after CAO (ST15M) predicted changes in Q and R waves 24 hours later; in the treated groups, the same ST15M prior to drug administration resulted in significantly less QRS changes. Thus, 1) Q wave development and R wave fall 24 hours after CAO accurately reflect myocardial necrosis. 2) ST15M predicts subsequent changes in Q and R waves. 3) The efficacy of hyaluronidase and propranolol, agents previously shown to reduce myocardial necrosis, can be detected by less Q wave development and a smaller fall in R wave voltage.

Cost-Effectiveness of Electronic Patient-Reported Outcome Measure Interventions in Cancer: Systematic Review and Parameter Extraction for Economic Modeling.
BACKGROUND: Complex digital interventions that integrate electronic patient-reported outcome measures (ePROM) into clinical practice in cancer have the potential to improve quality of life, increase survival, and reduce health resource use and costs. Such systems can help patients with cancer self-manage chemotherapy symptoms, reduce clinicians' workloads through automated decision support, and resolve problems earlier. However, more research on the cost-effectiveness of ePROM monitoring is needed. OBJECTIVE: This paper comprises two complementary components: (1) a systematic literature review summarizing and evaluating the quantitative and qualitative evidence related to the cost-effectiveness of ePROM monitoring and (2) a health economic model parameter extraction. We also conducted supplementary targeted searches and scoping to provide context to our findings. METHODS: We searched Ovid (including MEDLINE and Embase), Scopus, and the International Health Technology Assessment Database for original English-language papers published on or before March 2025 using search strings that combined terms related to ePROMs, health economics, and cancer/oncology. We included papers reporting health economic-related outcomes for ePROM interventions designed for adult cancer populations and excluded screening tools and conference abstracts. RESULTS: We included 34 publications from 27 unique studies and identified and analyzed 26 ePROM-integrated interventions within these. Most (23/26) of the included interventions explicitly described some form of alert handling and automated decision support based on remote ePROM monitoring. Of the 34 publications, 5 presented full cost-effectiveness analysis results, of which 3 were highly uncertain and lacked clear differences in costs and health outcomes between ePROMs and standard care; conversely, 2 presented strong evidence of cost-effectiveness due to quality-of-life improvements, reduced hospitalizations, and potentially more autonomy in health-related travel (eg, ePROM-monitored patients can drive or walk to the hospital instead of using taxis or ambulances). A further 5 publications reported partial health economic results (eg, cost-consequence and budget impact), of which 1 detected no difference in strategies; in contrast, 4 reported lower health resource use and costs of ePROMs, mainly due to hospitalization reductions. Overall, 12 of the 27 studies included a qualitative component but mostly focused on user experience and design-related themes; only 2 of these addressed economic-specific themes (eg, changes in workflow and resource use due to ePROM implementation and integration), indicating some potential for time saving due to ePROM monitoring. CONCLUSIONS: Some ePROM-integrated interventions demonstrated cost-effectiveness in cancer care, but the evidence base remains limited. Where evidence does exist, cost-effectiveness appears driven by reduced hospitalization and improved quality of life. Qualitative research within the included studies rarely addressed economic questions. We provide a detailed parameter extraction for use in future economic modeling and recommend research priorities, including quantitative mapping of ePROM symptom data onto health resource use patterns, and qualitative work exploring how ePROM implementation affects clinical workloads and patient-perspective costs.

Process evaluation of a nurse-led transitional care model (Cardiolotse) within a randomized controlled trial aiming to improve care coordination for patients with cardiovascular diseases in Germany.
BACKGROUND: Patients with higher age suffering from cardiovascular disease discharged from hospital are at greater risk of readmission within 30 days. We evaluated an innovative care program providing post-discharge support and helping patients to navigate through the healthcare system. This paper reports the findings of the process evaluation of the randomized controlled trial Cardiolotse, a nurse-led transitional care model improving care coordination for patients with cardiovascular diseases in Germany. METHODS: A process evaluation, following the guidelines of the Medical Research Council (MRC) Framework, was performed. Semi-structured interviews with all relevant target groups were conducted to gain more insight about implementation processes. Questionnaires and medical records were used to explore mechanisms of impact and understand how change was produced in the intervention. Qualitative data were analysed using content analysis with deductive and inductive categories. Descriptive statistics and subgroup analyses were utilized to explore quantitative data. RESULTS: Overall, the designed training programme was perceived positively by the study nurses, so called Cardiolotsen (CLs). Patients receiving support by the CLs reported positive satisfaction ratings. Interactions between CLs and patients were reported as trustworthy and reliable. A total of approximately 12,500 contacts were made over the course of the intervention. However, changes in satisfaction scores between intervention and control groups in terms of medical treatment or the interaction between medical health providers involved in the treatment could not be determined. Furthermore, data suggested reach issues with respect to office-based physicians, as regular CL contact could not be achieved with 90% of the participating general practitioners and cardiologists. CONCLUSIONS: The CLs served as an important source of support for the participating patients throughout the intervention. At regular intervals, they checked a patient's health status and their adherence to therapies after discharge. However, the process evaluation identified cross-sectoral communication and information exchange between CLs and office-based physicians as an implementation challenge. TRIAL REGISTRATION: The study was retrospectively registered at German Clinical Trial Register, http://www.drks.de/DRKS00020424 (Trial Registration Number DRKS00020424) on 18 June 2020.

OctopuSV and TentacleSV: a one-stop toolkit for multi-sample, cross-platform structural variant comparison and analysis.
MOTIVATION: Structural variants (SVs) influence gene regulation, disease progression, and diagnostics, yet integrating SV calls across platforms remains difficult due to inconsistent annotations, limited merging flexibility, and fragmented workflows. Ambiguous breakend (BND) annotations, which comprise many variant calls, are often discarded or misclassified, hindering variant characterization. Existing tools lack advanced merging operations essential for precise identification of disease-specific or somatic variants across samples or patient groups. Additionally, current SV analysis pipelines require extensive manual intervention and complex parameter tuning, compromising reproducibility and scalability. Addressing these gaps is crucial for improving the accuracy, interpretability, and clinical utility of SV analyses. RESULTS: We developed OctopuSV and TentacleSV to address these long-standing challenges in SV analysis. OctopuSV features a specialized BND correction module that converts ambiguous BND annotations into canonical SV types, recovering important variants that are often overlooked by existing tools. Additionally, it provides advanced set operations (difference, complement, custom-defined) that enable sophisticated variant filtering without programming expertise, critical for identifying tumor-specific SVs or variants unique to specific sample groups. TentacleSV completes our solution by automating the entire SV analysis process from raw sequencing data to high-confidence callsets, ensuring consistency and reproducibility across projects. Benchmarking across short-read and long-read platforms showed superior F1 score, complete SV type consistency compared to existing tools. Our framework enables experimental biologists and clinical researchers to perform sophisticated analyses ranging from cancer subtype-specific SV identification to multi-sample comparative studies without requiring specialized programming skills. AVAILABILITY AND IMPLEMENTATION: All codes are available at https://github.com/ylab-hi/OctopuSV; https://github.com/ylab-hi/TentacleSV.

[Pain-sensation following classic neck-dissection (author's transl)].
Resulting neck-dissection surgery (including curative or conservative intervention) very complex pain-syndromes are next to losses of function at the top of complaints stated. The discussion of the case-reports of 242 patients with unilateral neck-dissection and the reexamination of 28 patients free of recurrence revealed several causes of head- and facial pain. The close relationship of functional disability and pain-sensation is discussed. The recommendation of elective neck-dissection - by critical indication - is supported. Resection of nervus accessorius may be necessary in some cases, immediate reconstruction by nerve sutures is recommended. By post-operative treatment the complaints often can be relieved.

The effect of mercury derivatives of fluorescencein on allotransplant kidney in experiment.
Mercurascan (MSC), a mercury derivative of fluorescein, was studied as to its effect on the survival of allogeneic kidney grafts in dogs. A single perfusion of the donor's kidney with saline solution with MSC added in a ratio of 1 mg/100 ml was found to have significantly extended the graft survival time from 10.8 days (SE +/- 0.6) to 15.4 days (SE +/- 1.6). Graft survival time extension proved to be even more significant after a single dose of MSC given to the donor (0.5 mg/kg b.w.) and repeated administration of an equal MSC dose to the recipient twice weekly. Listed are detailed morphological changes in tissue specimens from the kidney, lymph nodes, spleen, and many other organs of a dog surviving for 42 days. A very moderate rejection lesion with merely tiny lymphocytic infiltrates was proved in the kidney. Lymph node structure was almost entirely obliterated with lymphoid tissue extinction. There was loss of white pulp in the spleen. The absence of morphological changes in the other organs suggested good tolerance of the preparation. More studies are called for to elucidate the complex MSC intervention in the process of rejection.

Regulation of collagenase. Therapeutic considerations.
Why the cornea ulcerates, in the sense of what goes awry, may be related to the trapping of wound healing in a phase of proteolytic debridement related to a persistent epithelial defect. The initial avascularity of the cornea makes it particularly vulnerable to proteolytic damage. Studies on the biochemistry and cell biology of corneal ulceration have indicated that sequential interactions occur which result in the generation of collagenase activity and the development of ulceration. It is likely that the interactions are susceptible to intervention; and it is thought that eventual, successful treatment of corneal ulceration will require a complex therapy, with interventions at multiple sites of regulation.
