Patients’ and Relatives’ Preferences for Outpatient and Day Care Services Within End-of-Life Care in Germany: a Discrete Choice Experiment
No full textPurpose: In Germany, patients with incurable chronic diseases living at home increasingly have the option of using outpatient and day care hospice and specialized palliative care services. The present study examined and compared patients’ and their relatives’ preferences for end-of-life outpatient and day care services. Patients and Methods: The study used a questionnaire integrating a discrete choice experiment. For six scenarios, participants chose between two hypothetical end-of-life care offers, described by seven attributes. The model compared place of care, frequency and duration of care and support, specialized medical palliative care, accompanied activities, and relieving patient counselling. The model also included optional overnight care and willingness to pay. Patients and the relatives of patients suffering from incurable, chronic diseases who were not yet receiving palliative care were recruited via hospitals and self-help groups (06/2021–07/2022). Results: The results were based on data from 436 questionnaires (patients: n=263, relatives: n=173). All attributes had a statistically significant impact on choice decisions, with place of care showing the greatest importance. All respondents highly preferred care in the patient’s home over out-of-home care. Patients stressed the importance of special medical (palliative) care and valued accompanied activities, often facilitated by hospice volunteers. Relatives, but not patients, considered the frequency and duration of care highly relevant. Conclusion: The results suggest a higher demand for care in the patient’s home than for out-of-home care. Patients’ and relatives’ high preference for special medical care and the relief of family caregiver burden should be considered in the design of day care services
Effectiveness of strontium/silver-based titanium surface coatings in improving antibacterial and osteogenic implant characteristics: a systematic review of in-vitro studies
No full textIntroduction: Due to the high incidence of implant failures, dual functionalization of titanium surfaces with antibacterial and osteogenic agents, like silver (Ag) and strontium (Sr), has gained significant attention in recent years. However, so far, the combined antibacterial and osteoinductive effectiveness of Ag/Sr-based titanium surface coatings has only been analyzed in individual studies. Methods: This systematic review aims to evaluate the existing scientific literature regarding the PICOS question "Does dual incorporation of strontium/silver enhances the osteogenic and anti-bacterial characteristics of Ti surfaces in vitro?". As a result of a web-based search adhering to the PRISMA Guidelines using three electronic databases (PubMed, Scopus, and Web of Science) until March 31, 2023, a total of 69 publications were identified as potentially relevant and 17 of which were considered appropriate for inclusion into this review. Results and Discussion: In all included publications, the use of Sr/Ag combination showed enhanced osteogenic and antibacterial effects, either alone or in combination with other agents. Moreover, the combination of Sr and Ag shows potential to synergistically enhance these effects. Nevertheless, further studies need to validate these findings under clinically more relevant conditions and evaluate the mechanism of antimicrobial and osteogenic activity of Sr/Ag combination
Adolescents with type 1 diabetes' perspectives on digital health interventions to enhance health literacy: a qualitative study
No full textIntroduction Digital health intervention offers the potential to enhance health literacy, which is crucial for effective diabetes management, especially among adolescents. Diabetes is a major global public health issue, leading to devastating complications and increasing mortality rates. The incidence of type 1 diabetes mellitus (T1DM) is also on the rise, particularly among adolescents, necessitating multisectoral strategies to combat this disease. This study explores the perceptions of adolescents with T1DM in Germany regarding digital health interventions, with the aim of improving healthcare by addressing specific needs and guiding future research. Methodology This study employed a qualitative approach using semi-structured individual interviews with adolescents with T1DM (n = 20) aged 14 to 18 years old in Germany to explore their perspectives on digital interventions for health literacy promotion. The study adopted content analysis according to Kuckartz et al. and the research followed the Consolidated Criteria for Reporting Qualitative Research (COREQ) checklist. Ethical considerations were paramount and data were rigorously analyzed using coding and iterative processes to ensure data quality and reliability. Results The findings indicate that within three prominent domains, namely the utilization of digital health intervention for accessing and comprehending information, facilitating peer-to-peer interactions, and enhancing physician-patient communication and interaction, digital health interventions are either underutilized or insufficiently deployed. In addition, a notable observation is the apparent lack of patient-centered approaches for adolescents with T1DM in relation to digital health interventions and health literacy. Conclusion In order to enhance the utilization of digital health interventions and enhance health literacy it is essential to focus on capacity building through a patient-centered approach, to promote digital health literacy, and foster the cultivation of a participatory culture. The outcomes of this study offer valuable insights that can inform practical applications, further research endeavors, and influence policymaking

An introduction to interpreting meta-analyses for orthodontists
Get PDFEvidence synthesis of primary orthodontic studies is crucial in advancing the dental and orthodontic field. The quality of conclusions delivered to the end-users of systematic reviews is contingent upon the appropriateness and diligence of the systematic review methods. The article provides a description of the core components of pairwise meta-analysis, a statistical tool that synthesises the findings of several related primary studies. Emphasis is placed on the features and good selection practices of the available meta-analysis models, proper visualisation of the results and the concept of statistical heterogeneity. A real-life systematic review is used to exemplify the introduced methods
Identification and characterization of mechanisms that facilitate Pseudomonas aeruginosa infection of human lung cells
No full textInvestigation of the relationship between neuroplasticity and grapheme-color synesthesia
No full textGrapheme-color synesthesia is a normal and healthy variation of human perception. It is characterized by the association of letters or numbers with color perceptions. The etiology of synesthesia is not yet fully understood. Theories include hyperconnectivity in the brain, cross-activation of adjacent or functionally proximate sensory areas of the brain, or various models of lack of inhibitory function in the brain. The growth factor brain-derived neurotrophic (BDNF) plays an important role in the development of neurons, neuronal pathways, and synapses, as well as in the protection of existing neurons in both the central and peripheral nervous systems. ELISA methods were used to compare BDNF serum concentrations between healthy test subjects with and without grapheme-color synesthesia to establish a connection between concentration and the occurrence of synesthesia. The results showed that grapheme-color synesthetes had an increased BDNF serum level compared to the matched control group. Increased levels of BDNF can enhance the brain's ability to adapt to changing environmental conditions, injuries, or experiences, resulting in positive effects. It is discussed whether the integration of sensory information is associated with or results from increased neuroplasticity. The parallels between neurodegeneration and brain regeneration lead to the conclusion that synesthesia, in the sense of an advanced state of consciousness, is in some cases a more differentiated development of the brain rather than a relic of early childhood
Cystinosis-Associated Metabolic Bone Disease Across Ages and CKD Stages 1 to 5D/T
No full textSupplemental Material zu folgender Publikation (Abstract) Context: The pathophysiology of cystinosis-associated metabolic bone disease is complex. Objective: We hypothesized a disturbed interaction between osteoblasts and osteoclasts. Methods: This binational cross-sectional multicenter study included 103 patients with cystinosis (61% children) with chronic kidney disease (CKD) stages 1 to 5D/T at hospital clinics. Ten key bone markers were evaluated. Results: Skeletal complications occurred in two-thirds of the patients, with adults having a 5-fold increased risk compared with children. Patients with CKD stages 1 to 3 showed reduced z-scores for serum phosphate and calcium and suppressed fibroblast growth factor 23 (FGF23) and parathyroid hormone levels, in conjunction with elevated bone-specific alkaline phosphatase levels. Serum phosphate was associated with estimated glomerular filtration rate, combined phosphate and active vitamin D treatment, and native vitamin D supplementation, while serum calcium was associated with age and dosage of active vitamin D. Sclerostin was generally elevated in children, and associated with age, FGF23 levels, and treatment with active vitamin D and growth hormone. The osteoclast marker tartrate-resistant acid phosphatase 5b was increased, and associated with age and treatment with active vitamin D. The ratio of soluble ligand of receptor activator of nuclear factor-κB (sRANKL) and osteoprotegerin (OPG), a surrogate for the regulation of osteoclastogenesis by osteoblasts, was decreased and associated with phosphate and 1,25(OH)2D3 levels. These changes were only partly corrected after transplantation. Conclusion: Bone health in cystinosis deteriorates with age, which is associated with increased osteoclast activity despite counter-regulation of osteoblasts via OPG/RANKL, which in conjunction with elevated sclerostin levels and persistent rickets/osteomalacia, may promote progressive bone loss
Long-term discontinuation of warfarin in a patient with HeartMate 3 left ventricular assist device without thromboembolic events.
No full textThe gold standard therapy for end-stage heart failure is cardiac transplantation. However, in the face of a donor shortage, a mechanical assist device such as the left ventricular assist device HeartMate 3 (Abbott Laboratories, Abbott Park, IL, USA) serves as bridging therapy to transplantation and/or destination therapy. Current guidelines recommend anticoagulation with a vitamin K antagonist in combination with low-dose aspirin. We herein report a challenging anticoagulation regimen in a patient with a HeartMate 3 in whom systemic anticoagulation with warfarin was not feasible for 4 years because of low compatibility and a rare X-factor deficiency. This is a rare hematological disorder, estimated to affect approximately 1 in every 500,000 to 1,000,000 people in the general population. The patient finally received a modified anticoagulation regimen involving the combination of rivaroxaban and clopidogrel without warfarin. Under this regimen, the patient remained free of thromboembolic complications for 4 years with in situ placement of the left ventricular assist device. This case illustrates that under specific circumstances, long-term absence of warfarin therapy is feasible in patients with a HeartMate 3
