RESUMO
BACKGROUND: Neurological diseases cause numerous challenges in palliative care. Telemedicine may improve the access to specialized expertise in neurology for patients, their relatives, and palliative care physicians. The TANNE study offers teleconsultations by a hospital-based neuropalliative center for specialized outpatient palliative care (SOPC) and hospices. A prospective, partially randomized, controlled trial aims at generating evidence for clinical improvements, quality of life, and cost efficiency. METHODS: SOPC and hospice teams in Bavaria, Germany, are partially randomized to one of two study arms, namely a treatment group with teleconsultations by specialists for neurology and palliative medicine or to a control group with interventions after a 12-months delay. Individual and population-based measures are assessed with a mixed-methods design in order to evaluate the medical effects, the potential for implementation in standard care, and health economic aspects. The primary outcome consists of the mean change difference between groups in the Integrated Palliative Care Outcome Scale (IPOS), which physicians assess before and after treatment of a neurological event. Besides, several secondary outcomes are investigated, including quality of life, which is measured with the revised McGill Quality of Life Questionnaire (McGill QOL-R) as well as items regarding general and health-related quality of life. Further secondary outcomes include the concrete progress of the neurological signs and symptoms; the subjective change in well-being since the start of the treatment of the neurological diseases from the perspectives of patients, their relatives, as well as medical and nursing professionals; as well as patient, professional, and caregiver satisfaction with the teleconsultations. Moreover, a health economic evaluation compares group differences regarding hospital visits and emergency calls with utilization measurements. DISCUSSION: The TANNE trial provides a comprehensive and complex evaluation design for teleconsultations in neuropalliative care. Ethical considerations need to take the patients' vulnerability into account. The project promises to substantially broaden the width of health care services and to improve the quality of life for deserving patients.

AIMS: To identify the histopathological features of transplant nephrectomy (TN) specimens. METHODS: We performed retrospective analysis of 73 nephrectomies to review the histopathology in detail and correlate the Banff grading characteristics of TN specimens with time post engraftment and clinical features. Retrospective data on donor-specific antibodies (DSA) were also collected. RESULTS: The majority of patients who had TN in less than 3 months posttransplant (n = 20; median time to TN: 4 days) had hemorrhagic infarction; 7 patients (35%) had grade 3 acute rejection (AR). Patients who had TN later than 3 months posttransplant (n = 53; median time to TN: 67 months) had AR, grade 2B (21%) and 3 (43%), coexisting with advanced vascular injury in the form of interstitial hemorrhage, extensive interstitial fibrosis and tubular atrophy (IF/TA) as well as the presence of DSAs. Overall, the majority of patients without DSA pre-TN developed DSA post-TN. CONCLUSIONS: Our data revealed extensive inflammation and ongoing immunologic activity in a subset of patients with a failed graft. Careful and individualized approach based on clinical and laboratory data should guide the decision for transplant nephrectomy.

Cardiovascular diseases (CVD) are a leading cause of death globally, and result in significant morbidity and reduced quality of life. The electrocardiogram (ECG) plays a crucial role in CVD diagnosis, prognosis, and prevention; however, different challenges still remain, such as an increasing unmet demand for skilled cardiologists capable of accurately interpreting ECG. This leads to higher workload and potential diagnostic inaccuracies. Data-driven approaches, such as machine learning (ML) and deep learning (DL) have emerged to improve existing computer-assisted solutions and enhance physicians' ECG interpretation of the complex mechanisms underlying CVD. However, many ML and DL models used to detect ECG-based CVD suffer from a lack of explainability, bias, as well as ethical, legal, and societal implications (ELSI). Despite the critical importance of these Trustworthy Artificial Intelligence (AI) aspects, there is a lack of comprehensive literature reviews that examine the current trends in ECG-based solutions for CVD diagnosis or prognosis that use ML and DL models and address the Trustworthy AI requirements. This review aims to bridge this knowledge gap by providing a systematic review to undertake a holistic analysis across multiple dimensions of these data-driven models such as type of CVD addressed, dataset characteristics, data input modalities, ML and DL algorithms (with a focus on DL), and aspects of Trustworthy AI like explainability, bias and ethical considerations. Additionally, within the analyzed dimensions, various challenges are identified. To these, we provide concrete recommendations, equipping other researchers with valuable insights to understand the current state of the field comprehensively.

BACKGROUND: Robots in healthcare are gaining increasing attention; however, their implementation is challenging due to the complexity of both interventions themselves and the contexts in which they are implemented. The objective of this integrative review is to identify barriers to and facilitators of the implementation of robotic systems in nursing. METHODS: Articles published from 2002 to 2019 reporting on projects to implement robotic devices in nursing care were searched on Medline (via PubMed), CINAHL and databases on funded research projects (Community Research and Development Information Services and Technische Informationsbibliothek) and in journals for robotic research in November 2017 and July 2019 for an update. No restrictions regarding study designs were imposed. All included articles underwent quality assessments with design-specific critical appraisal tools. Barriers to and facilitators of implementation were classified using the Context and Implementation of Complex Interventions framework. RESULTS: After removing all duplicates, the search revealed 11 204 studies, of which 17 met the inclusion criteria and were included in the synthesis. The majority of the studies dealt with the implementation of robots designed to support individuals, either living at home or in nursing homes (n=11). The studies were conducted in Europe, the USA and New Zealand and were carried out in nursing homes, individual living environments, hospital units and laboratories. The quality of reporting and quality of evidence were low in most studies. The most frequently reported barriers were in socioeconomic and ethical domains and were within the implementation outcomes domain. The most frequently reported facilitators were related to the sociocultural context, implementation process and implementation strategies. DISCUSSION: This review identified barriers to and facilitators of the implementation of robotic devices in nursing within different dimensions. The results serve as a basis for the development of suitable implementation strategies to reduce potential barriers and promote the integration of elements to facilitate implementation.

Because hypertension is common and many tests are available, an uncritical approach to laboratory and radiologic evaluation leads to unnecessary expenses. However, in most patients, accurate blood pressure measurement, a focused history and physical examination, and a handful of basic tests are enough. In this review we address the key questions in the evaluation of the patient with an elevated pressure reading, ie, does the patient have sustained high blood pressure? And if so, is the hypertension primary or secondary, are other cardiovascular risk factors present, and is there evidence of target organ damage?

Hypoxia is a potent regulator of a multitude of cellular processes, including metabolism and cell survival. The transcriptional response to oxygen deprivation is mainly mediated by hypoxia-inducible factors (HIFs), which are targeted for proteasomal degradation by the von Hippel-Lindau tumor suppressor protein (pVHL) under normoxia. Podocytes, as part of the glomerular filtration barrier, are prone to hypoxic injury during diseases affecting the glomerulus. VHL and HIF1 were functional in mature murine podocytes in vivo and in vitro, with HIF1 protein stabilization and target gene transcription under both hypoxia and VHL deficiency. Podocyte-specific Vhlh gene loss, mimicking podocyte hypoxia, in young mice of mixed background led to glomerulomegaly and occasional glomerulosclerosis, despite preserved glomerular development. In parallel, hypoxia effects on podocytes in cell culture included increased susceptibility to apoptosis, associated with nuclear translocation of apoptosis-inducing factor (AIF). Similarly, Vhlh gene inactivation in podocytes in vitro resulted in a significant survival disadvantage, particularly in conjunction with additional proapoptotic stimuli. Evaluation of the global transcriptional response to hypoxia in podocytes by microarray analysis revealed a typical upregulation of HIF target genes as well as the induction of genes relevant for stress response, cell-cell, and cell-extracellular matrix interaction. While the lack of a prominent phenotype in young mice with VHL-deficient podocytes is consistent with the absence of specific glomerular manifestations in human VHL disease, a low-oxygen environment of podocytes may contribute to the progression of glomerular disease by altering cellular metabolism and survival.

Glomerular disease associated with nephrotic syndrome has rarely been recognized as a distinct complication of allogeneic hematopoietic cell transplantation. Case reports in the English and Japanese literature since 1988 have described variable glomerular histology, comprising mainly membranous glomerulonephritis (MGN) in almost two thirds and minimal change disease (MCD) in nearly one quarter of patients. Review of the literature reveals a close temporal relationship between the development of nephrotic syndrome shortly after cessation of immunosuppression and the diagnosis of chronic graft-versus-host disease (GVHD). An association of glomerular disease with simultaneous GVHD was seen in 47% of patients overall. Nephrotic syndrome followed GVHD within 5 months in 60% of the combined MCD and MGN reports. A decrease in immunosuppressive medication use was linked to nephrotic syndrome occurrence within 9 months in 63% of patients with MCD and MGN. MCD occurred earlier after hematopoietic cell transplantation, was diagnosed sooner after medication change, and exhibited a better prognosis in comparison with MGN. Glomerular lesions after hematopoietic cell transplantation may therefore represent the renal manifestation of GVHD. Further studies are warranted to delineate the pathogenesis of this complication.
