Background: It is unclear whether optimising intraoperative cardiac index can reduce postoperative complications. We tested the hypothesis that maintaining optimised postinduction cardiac index during and for the first 8 h after surgery reduces the incidence of a composite outcome of complications within 28 days after surgery compared with routine care in high-risk patients having elective major open abdominal surgery., Methods: In three German and two Spanish centres, high-risk patients having elective major open abdominal surgery were randomised to cardiac index-guided therapy to maintain optimised postinduction cardiac index (cardiac index at which pulse pressure variation was <12%) during and for the first 8 h after surgery using intravenous fluids and dobutamine or to routine care. The primary outcome was the incidence of a composite outcome of moderate or severe complications within 28 days after surgery., Results: We analysed 318 of 380 enrolled subjects. The composite primary outcome occurred in 84 of 152 subjects (55%) assigned to cardiac index-guided therapy and in 77 of 166 subjects (46%) assigned to routine care (odds ratio: 1.87, 95% confidence interval: 1.03-3.39, P=0.038). Per-protocol analyses confirmed the results of the primary outcome analysis., Conclusions: Maintaining optimised postinduction cardiac index during and for the first 8 h after surgery did not reduce, and possibly increased, the incidence of a composite outcome of complications within 28 days after surgery compared with routine care in high-risk patients having elective major open abdominal surgery. Clinicians should not strive to maintain optimised postinduction cardiac index during and after surgery in expectation of reducing complications., Clinical Trial Registration: NCT03021525., (Copyright © 2024 The Author(s).

Background: Kidney transplantation (KTx) from small donors is associated with inferior graft survival in registry studies, whereas single-center studies show favorable results., Methods: We compared 175 pediatric KTx from small donors ≤20 kg (SDKTx) with 170 age-matched recipients from adult donors (ADKTx) from 20 centers within the Cooperative European Paediatric Renal Transplant Initiative registry. Graft survival and estimated glomerular filtration rate (eGFR) were analyzed by Cox regression and mixed models. Detailed data on surgical and medical management were tested for association with graft survival., Results: One-year graft survival was lower after SDKTx compared with ADKTx (90.9% versus 96.5%; odds ratio of graft loss, 2.92; 95% confidence interval [CI], 1.10-7.80; P  = 0.032), but 5-y graft survival was comparable (90.9% versus 92.7%; adjusted hazard ratio of graft loss 1.9; 95% CI, 0.85-4.25; P  = 0.119). SDKTx recipients had an annual eGFR increase of 8.7 ± 6.2 mL/min/1.73 m² compared with a decrease of 6.9 ± 5.7 mL/min/1.73 m² in ADKTx recipients resulting in a superior 5-y eGFR (80.5 ± 25.5 in SDKTx versus 65.7 ± 23.1 mL/min/1.73 m² in ADKTx; P  = 0.008). At 3 y posttransplant, eGFR after single SDKTx was lower than after en bloc SDKTx (86.6 ± 20.4 versus 104.6 ± 35.9; P  = 0.043) but superior to ADKTx (68.1 ± 23.9 mL/min/1.73 m²). Single-kidney SDKTx recipients had a lower rate of hypertension at 3 y than ADKTx recipients (40.0% versus 64.7%; P  = 0.008)., Conclusions: Compared with ADKTx, 5-y graft function is superior in SDKTx and graft survival is similar, even when performed as single KTx. Utilizing small donor organs, preferably as single kidneys in experienced centers, is a viable option to increase the donor pool for pediatric recipients., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2024 Wolters Kluwer Health, Inc.

Background: The TIM-HF2 study demonstrated that remote patient management (RPM) in a well-defined heart failure (HF) population reduced the percentage of days lost due to unplanned cardiovascular hospital admissions or all-cause death during 1-year follow-up (hazard ratio 0.80) and all-cause mortality alone (HR 0.70). Higher rates of hospital admissions and mortality have been reported in HF patients with diabetes compared with HF patients without diabetes. Therefore, in a post-hoc analysis of the TIM-HF2 study, we investigated the efficacy of RPM in HF patients with diabetes., Methods: TIM-HF2 study was a randomized, controlled, unmasked (concealed randomization), multicentre trial, performed in Germany between August 2013 and May 2018. HF-Patients in NYHA class II/III who had a HF-related hospital admission within the previous 12 months, irrespective of left ventricular ejection fraction, and were randomized to usual care with or without added RPM and followed for 1 year. The primary endpoint was days lost due to unplanned cardiovascular hospitalization or due to death of any cause. This post-hoc analysis included 707 HF patients with diabetes., Results: In HF patients with diabetes, RPM reduced the percentage of days lost due to cardiovascular hospitalization or death compared with usual care (HR 0.66, 95% CI 0.48-0.90), and the rate of all-cause mortality alone (HR 0.52, 95% CI 0.32-0.85). RPM was also associated with an improvement in quality of life (mean difference in change in global score of Minnesota Living with Heart Failure Questionnaire score (MLHFQ): - 3.4, 95% CI - 6.2 to - 0.6)., Conclusion: These results support the use of RPM in HF patients with diabetes., Clinical Trial Registration: ClinicalTrials.gov NCT01878630., (© 2024.

Background: Tacrolimus, a calcineurin inhibitor (CNI), is currently the first-line immunosuppressive agent in kidney transplantation. The therapeutic index of tacrolimus is narrow due to due to the substantial impact of minor variations in drug concentration or exposure on clinical outcomes (i.e., nephrotoxicity), and it has a highly variable intra- and inter-individual bioavailability. Non-adherence to immunosuppressants is associated with rejection after kidney transplantation, which is the main cause of long-term graft loss. Once-daily formulations have been shown to significantly improve adherence compared to twice-daily dosing. Envarsus ® , the once-daily prolonged-release formulation of tacrolimus, offers the same therapeutic efficacy as the conventional twice-daily immediate-release tacrolimus formulation (Prograf ® ) with improved bioavailability, a more consistent pharmacokinetic profile, and a reduced peak to trough, which may reduce CNI-related toxicity. Envarsus ® has been approved as an immunosuppressive therapy in adults following kidney or liver transplantation but has not yet been approved in children. The objective of this study is to evaluate the pharmacokinetic profile, efficacy, and tolerability of Envarsus ® in children and adolescents aged ≥ 8 and ≤ 18 years to assess its potential role as an additional option for immunosuppressive therapy in children after kidney transplantation., Methods/design: The study is designed as a randomized, prospective crossover trial. Each patient undergoes two treatment sequences: sequence 1 includes 4 weeks of Envarsus ® and sequence 2 includes 4 weeks of Prograf ® . Patients are randomized to either group A (sequence 1, followed by sequence 2) or group B (sequence 2, followed by sequence 1). The primary objective is to assess equivalency between total exposure (of tacrolimus area under the curve concentration (AUC0-24)), immediate-release tacrolimus (Prograf ® ) therapy, and prolonged-release tacrolimus (Envarsus ® ) using a daily dose conversion factor of 0.7 for prolonged- versus immediate-release tacrolimus. Secondary objectives are the assessment of pharmacodynamics, pharmacogenetics, adherence, gut microbiome analyses, adverse events (including tacrolimus toxicity and biopsy-proven rejections), biopsy-proven rejections, difference in estimated glomerular filtration rate (eGFR), and occurrence of donor-specific antibodies (DSAs)., Discussion: This study will test the hypothesis that once-daily prolonged-release tacrolimus (Envarsus ® ) is bioequivalent to twice-daily intermediate-release tacrolimus after pediatric kidney transplantation and may reduce toxicity and facilitate medication adherence. This novel concept may optimize immunosuppressive therapy for more stable graft function and increased graft survival by avoiding T-cell mediated and/or antibody-mediated rejection due to improved adherence. In addition, the study will provide data on the pharmacodynamics and pharmacogenetics of prolonged-release tacrolimus in children and adolescents., Clinical Trial Registration: EUDRA-CT 2019-003710-13 and ClinicalTrial.gov, identifier NCT06057545., Competing Interests: LP, JO, and LW received honoraria as speakers from Chiesi Germany GmbH.

Aims: Remote patient management (RPM) in heart failure (HF) patients has beneficial clinical effects. This analysis investigates the effects of RPM used in the Telemedical Interventional Management in Heart Failure II (TIM-HF2) trial on HF-specific self-care., Methods and Results: From 2013 to 2017, 1538 HF outpatients (age 70.3 ± 10.5 years, 70% men, 52%/47% NYHA II/III, 65% LVEF ≤45%) with a recent HF hospitalization were included to the study and randomized to usual care (UC) plus RPM (n = 796) or UC only (n = 775), with a 12-month follow-up. Self-reported self-care behaviour at baseline and at end of study was assessed with the 9-item European Heart Failure Self-care Behaviour Scale (EHFScBS-9), obtaining 1321 patients with valid baseline and follow-up questionnaires for the analysis. EHFScBS-9 sum scores increased in the RPM group (n = 667) from 78.7 ± 17 to 84.5 ± 14 and in the UC group (n = 654) from 79.0 ± 17 to 80.0 ± 16 from baseline to 12 months [difference in means (MD) 4.58 (3.02, 6.14); P < 0.001] with highest improvement [8.66 (3.52; 13.81)] in patients living alone and having an inadequate (<70) baseline EHFScBS-9. There were differences between both groups in item 'I weight myself every day' [MD -1.13 (-1.24, -1.02); P < 0.001] and item 'I take my medication as prescribed' [MD -0.06 (-0.10, -0.01); P = 0.014]. No correlation was found between the EHFScBS-9 score and the efficacy of RPM on the TIM-HF2 primary endpoint of percentage of days lost due to unplanned cardiovascular hospitalization or death of any cause., Conclusions: RPM improves HF-specific self-care behaviour by achieving a better adherence to recommended HF regimen., Registration: ClinicalTrials.gov: NCT01878630., Competing Interests: Conflicts of interest: F.K. has received fees for presentation from AMGEN GmbH, Sanofi-Aventis Deutschland GmbH, Abbott Medical GmbH, AstraZeneca, BIOTRONIK, Boehringer Ingelheim, and Novartis; Scientific Grants from German Federal Ministry of Science and Education (BMBF), German Federal Ministry of Economics and Climate Protection (BMWK), and advisory boards from Sanofi-Aventis Deutschland GmbH, BIOTRONIK.

Objective: Novel deep brain stimulation (DBS) systems allow directional and short-pulse stimulation to potentially improve symptoms and reduce side effects. The aim of this study was to investigate the effect of short-pulse and directional stimulation, in addition to a combination of both, in the ventral intermediate thalamus (VIM)/posterior subthalamic area (PSA) on tremor and stimulation-induced side effects in patients with essential tremor., Materials and Methods: We recruited 11 patients with essential tremor and VIM/PSA-DBS. Tremor severity (Fahn-Tolosa-Marin), ataxia (International Cooperative Ataxia Rating Scale), and paresthesia (visual analog scale) were assessed with conventional omnidirectional and directional stimulation with pulse width of 60 μs and 30 μs., Results: All stimulation conditions reduced tremor. The best directional stimulation with 60 μs reduced more tremor than did most other stimulation settings. The best directional stimulation, regardless of pulse width, effectively reduced stimulation-induced ataxia compared with the conventional stimulation (ring 60 μs) or worst directional stimulation with 60 μs. All new stimulation modes reduced occurrence of paresthesia, but only the best directional stimulation with 30 μs attenuated paresthesia compared with the conventional stimulation (ring 60 μs) or worst directional stimulation with 60 μs. The best directional stimulation with 30 μs reduced tremor, ataxia, and paresthesia compared with conventional stimulation in most patients. Correlation analyses indicated that more anterior stimulation sites are associated with stronger ataxia reduction with directional 30 μs than with conventional 60 μs stimulation., Conclusion: Directional and short-pulse stimulation, and a combination of both, revealed beneficial effects on stimulation-induced adverse effects., (Copyright © 2022 International Neuromodulation Society.

Guanidino compounds such as dimethylarginines (SDMA, ADMA) and L-homoarginine ((L-)hArg) can interfere with bioavailability and function of the main NO-donor L-arginine (L-Arg). High ADMA and SDMA but low L-hArg concentrations have been associated with cardio- and cerebrovascular events and mortality in adults. The role of guanidino compounds in paediatric patients remains less clear. We, therefore, compared guanidino compound levels in plasma samples of 57 individuals with chronic kidney disease (CKD) and 141 individuals without CKD from the age of 0 to 17 years, including patients with different comorbidities by correlation and regression analyses. We found highest hArg, SDMA and ADMA concentrations in neonates (Kruskal-Wallis, p < 0.001 for all). From the age of 1 year on, hArg levels increased, whereas SDMA und ADMA levels further decreased in children. SDMA and ADMA are higher in children with CKD independent of GFR (mean factor 1.92 and 1.38, respectively, p < 0.001 for both), and SDMA is strongly correlated with creatinine concentration in children with CKD (Spearman's rho 0.74, p < 0.001). We provide guanidino compound levels in a large sample covering all paediatric age groups for the first time. Our data can be used to assess the role of guanidino compounds such as hArg in disease states, i.e. cerebro- and cardiovascular disorders in childhood and adolescence., (© 2023. The Author(s).)

Homoarginine is associated with cardio- and cerebrovascular morbidity and mortality. However, the underlying pathomechanisms remain elusive. Here, we evaluated the association of homoarginine with adverse events (i.e., death, stroke, and myocardial infarction) and carotid intima-media thickness (cIMT) in stroke patients. In the prospective bioMARKers in STROKE (MARK-STROKE) cohort, patients with acute ischemic stroke or transient ischemic attack (TIA) were enrolled. Plasma homoarginine concentrations were analyzed and associated with clinical phenotypes in cross-sectional (374 patients) and prospective (273 patients) analyses. Adjustments for possible confounders were evaluated. A two-fold increase in homoarginine was inversely associated with the National Institutes of Health Stroke Scale (NIHSS) score at admission, cIMT, and prevalent atrial fibrillation (mean factor -0.68 [95% confidence interval (CI): -1.30, -0.07], -0.14 [95% CI: -0.22, -0.05]; and odds ratio 0.57 [95% CI: 0.33, 0.96], respectively). During the follow-up (median 284 [25th, 75th percentile: 198, 431] days), individuals with homoarginine levels in the highest tertile had fewer incident events compared with patients in the lowest homoarginine tertile independent of traditional risk factors (hazard ratio 0.22 [95% CI: 0.08, 0.63]). A lower prevalence of atrial fibrillation and a reduced cIMT pinpointed potential underlying pathomechanisms.

Background: Antidepressants are established as an evidence-based, guideline-recommended treatment for Major Depressive Disorder. Prescriptions have markedly increased in past decades, with a specific surge in maintenance prescribing. Patients often remain on antidepressants longer than clinically necessary. When attempting to stop, many patients experience adverse discontinuation symptoms. Discontinuation symptoms can be debilitating and hinder successful discontinuation. While discontinuation symptoms can result from pharmacological effects, evidence on nocebo-induced side effects of antidepressant use suggests that patients' expectations may also influence occurrence., Methods: To disentangle pharmacological and expectation effects in antidepressant discontinuation, patients with fully remitted Major Depressive Disorder who fulfill German guideline recommendations to discontinue will either remain on or discontinue their antidepressant. Participants' expectations will be manipulated by varying verbal instructions using an open-hidden paradigm. Within the open trial arms, participants will receive full information about treatment, i.e., high expectation. Within the hidden trial arms, participants will be informed about a 50% chance of discontinuing versus remaining on their antidepressant, i.e., moderate expectation. A total of N = 196 participants will be randomly assigned to either of the four experimental groups: open discontinuation (OD; n = 49), hidden discontinuation (HD; n = 49), open continuation (OC; n = 49), or hidden continuation (HC; n = 49). Discontinuation symptom load during the 13-week experimental phase will be our primary outcome measure. Secondary outcome measures include discontinuation symptom load during the subsequent 39-week clinical observation phase, recurrence during the 13-week experimental period, recurrence over the course of the complete 52-week trial evaluated in a time-to-event analysis, and stress, anxiety, and participants' attentional and emotional processing at 13 weeks post-baseline. Blood and saliva samples will be taken as objective markers of antidepressant blood serum level and stress. Optional rsfMRI measurements will be scheduled., Discussion: Until today, no study has explored the interplay of pharmacological effects and patients' expectations during antidepressant discontinuation. Disentangling their effects has important implications for understanding mechanisms underlying adverse discontinuation symptoms. Results can inform strategies to manage discontinuation symptoms and optimize expectations in order to help patients and physicians discontinue antidepressants more safely and effectively., Trial Registration: ClinicalTrials.gov (NCT05191277), January 13, 2022., (© 2023.

Background: Single elements of the Closed Loop Medication Management process (CLMM), including electronic prescribing, involvement of clinical pharmacists (CPs), patient individual logistics and digital administration/documentation, have shown to improve medication safety and patient health outcomes. The impact of the complete CLMM on patient safety, as reflected in pharmacists' interventions (PIs), is largely unknown. Aim: To evaluate the extent and characterization of routine PIs performed by hospital-wide CPs at a university hospital with an implemented CLMM. Methods: This single-center study included all interventions documented by CPs on five self-chosen working days within 1 month using the validated online-database DokuPIK (Documentation of Pharmacists' Interventions in the Hospital). Based on different workflows, two groups of CPs were compared. One group operated as a part of the CLMM, the "Closed Loop Clinical Pharmacists" (CL-CPs), while the other group worked less dependent of the CLMM, the "Process Detached Clinical Pharmacists" (PD-CPs). The professional experience and the number of medication reviews were entered in an online survey. Combined pseudonymized datasets were analyzed descriptively after anonymization. Results: A total of 1,329 PIs were documented by nine CPs. Overall CPs intervened in every fifth medication review. The acceptance rate of PIs was 91.9%. The most common reasons were the categories "drugs" (e.g., indication, choice of formulation/drug and documentation/transcription) with 42.7%, followed by "dose" with 29.6%. One-quarter of PIs referred to the therapeutic subgroup "J01 antibacterials for systemic use." Of the 1,329 underlying PIs, 1,295 were classified as medication errors (MEs) and their vast majority (81.5%) was rated as "error, no harm" (NCC MERP categories B-D). Among PIs performed by CL-CPs ( n = 1,125), the highest proportion of errors was categorized as B (56.5%), while in the group of PIs from PD-CPs ( n = 170) errors categorized as C (68.2%) dominated ( p < 0.001). Conclusion: Our study shows that a structured CLMM enables CPs to perform a high number of medication reviews while detecting and solving MEs at an early stage before they can cause harm to the patient. Based on key quality indicators for medication safety, the complete CLMM provides a suitable framework for the efficient medication management of inpatients., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Berger, Sommer, Boje, Hollmann, Hummelt, König, Lezius, Linde, Marhenke, Melzer, Michalowski, Baehr and Langebrake.)

Background: According to recent legislation, facilitated advance care planning (ACP) for nursing home (NH) residents is covered by German sickness funds. However, the effects of ACP on patient-relevant outcomes have not been studied in Germany yet. This study investigates whether implementing a complex regional ACP intervention improves care consistency with care preferences in NH residents., Methods: This is a parallel-group cluster-randomized controlled trial (cRCT) with 48 NHs (≈ 3840 resident beds) between 09/2019 and 02/2023. The intervention group will receive a complex, regional ACP intervention aiming at sustainable systems redesign at all levels (individual, institutional, regional). The intervention comprises comprehensive training of ACP facilitators, implementation of reliable ACP processes, organizational development in the NH and other relevant institutions of the regional healthcare system, and education of health professionals caring for the residents. Control group NHs will deliver care as usual. Primary outcome is the hospitalization rate during the 12-months observation period. Secondary outcomes include the rate of residents whose preferences were known and honored in potentially life-threatening events, hospital days, index treatments like resuscitation and artificial ventilation, advance directives, quality of life, psychological burden on bereaved families, and costs of care. The NHs will provide anonymous, aggregated data of all their residents on the primary outcome and several secondary outcomes (data collection 1). For residents who have given informed consent, we will evaluate care consistency with care preferences and further secondary outcomes, based on chart reviews and short interviews with residents, surrogates, and carers (data collection 2). Process evaluation will aim to explain barriers and facilitators, economic evaluation the cost implications., Discussion: This study has the potential for high-quality evidence on the effects of a complex regional ACP intervention on NH residents, their families and surrogates, NH staff, and health care utilization in Germany. It is the first cRCT investigating a comprehensive regional ACP intervention that aims at improving patient-relevant clinical outcomes, addressing and educating multiple institutions and health care providers, besides qualification of ACP facilitators. Thereby, it can generate evidence on the potential of ACP to effectively promote patient-centered care in the vulnerable population of frail and often chronically ill elderly., Trial Registration: ClinicalTrials.gov ID NCT04333303 .

Background and Aims: Effective high density lipoprotein cholesterol (HDL-C) is a measure of HDL functionality. We evaluated if HDL-C is associated with carotid intima-media thickness (cIMT) and incident major adverse cardiovascular events (MACE) in patients with acute ischemic stroke from two prospective cohort studies., Methods: In the MARK-STROKE cohort, 299 patients with acute ischemic stroke or TIA were included. Outcome was available in 219 patients during a median follow-up of 294 days. In CIRCULAS, 382 acute ischemic stroke patients were included and a 90-day follow-up was available in 213 patients. HDL-C was calculated based on symmetric dimethylarginine (SDMA) and HDL cholesterol concentrations. Main outcome was incident MACE (death, stroke, and myocardial infarction) and the main measure was cIMT., Results: In both studies, HDL-C was inversely associated with cIMT in linear regression analysis adjusted for age, sex and creatinine. In MARK-STROKE, the adjusted hazard for MACE was significantly reduced for patients with one unit increase (mg/dL) of HDL-C (hazard ratio 0.95 [95% confidence interval (CI): 0.92, 0.99]). In the CIRCULAS cohort, stroke patients with higher HDL-C had less incident MACE during 90 days of follow-up (odds ratio: 0.97 [95% CI: 0.94, 0.99] for one unit increase). Neither SDMA nor HDL cholesterol predicted outcome., Conclusions: Our findings imply a protective role of biologically effective HDL after acute cerebral ischemia for secondary events and emphasize the relevance of lipoprotein functionality in these patients., Competing Interests: Declaration of interests The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier B.V.

Background: Mucopolysaccharidoses (MPS) are a group of rare metabolic diseases characterized by a wide spectrum of symptoms including progressive condylar resorption., Aim: The aim of this study was to quantify the severity of condylar involvement in MPS I individuals in comparison with a group of non-MPS individuals and to describe how condylar changes may vary among the different types of MPS., Design: Fifty panoramic radiographs of MPS patients (13.4 ± 6.2 years) with MPS I (n = 14), MPS II (n = 2), MPS IV (n = 8) and MPS VI (n = 2) were compared with forty panoramic radiographs of non-MPS individuals. The severity of condylar resorption was evaluated using a qualitative score (grades 0-3) and using the ratio of condylar height to ramus height (CH: RH)., Results: All MPS I and VI individuals showed pronounced bilateral degenerative condylar resorption. In contrast, individuals with MPS II and IV exhibited heterogeneous findings. The quantification of condylar height to ramus height revealed that CH: RH was significantly decreased in MPS I as compared to that of non-MPS individuals (P < .001). In contrast, the CH: RH ratios of MPS II and IV showed great variability., Conclusion: Mucopolysaccharidoses subtypes differ with regard to the severity of condylar resorption., (© 2021 The Authors.

Background: Persons with multiple sclerosis (MS) are confronted by an overwhelming amount of online health information, which can be valuable but also vary in quality and aim. Therefore, it is of great importance for developers and providers of eHealth information to understand its impact on the users. The eHealth Impact Questionnaire (eHIQ) has been developed in the United Kingdom to measure the potential effects of health and experimental information websites. This contains user's general attitudes towards using the internet to gain health information and attitudes towards a specific health related website. The self-complete questionnaire is divided into two independently administered and scored parts: the 11-item eHIQ part 1 and the 26-item eHIQ part 2. This study aimed to validate the psychometric properties of the German version of the eHealth Impact Questionnaire (eHIQ-G)., Methods: 162 people with multiple sclerosis browsed one of two possible websites containing information on MS and completed an online survey. Internal consistency was assessed by Cronbach's alpha and structural validity by Confirmatory Factor Analysis. Construct validity was examined by assessing correlations with the reference instruments eHealth Literacy Questionnaire and the General Self-Efficacy Scale measuring related, but dissimilar constructs. Moreover, we investigated the mean difference of the eHIQ-G score between the two websites. Data were analyzed using SPSS and AMOS software., Results: The eHIQ-G subscales showed high internal consistency with Cronbach's alpha from 0.833 to 0.885. The 2-factor model of eHIQ part 1 achieved acceptable levels of goodness-of-fit indices, whereas the fit for the 3-factor model of eHIQ part 2 was poor and likewise for the alternative modified models. The correlations with the reference instruments were 0.08-0.62 and as expected. Older age was related with lower eHIQ part 1 score, whereas no significant effect was found for education on eHIQ part 1. Although not significant, the website 'AMSEL' reached higher mean scores on eHIQ part 2., Conclusions: The eHIQ-G has good internal consistency, and sufficient structural and construct validity. This instrument will facilitate the measurement of the potential impact of eHealth tools., (© 2022. The Author(s).)

Purpose: We aimed to investigate whether left ventricular diastolic dysfunction (LVDD) is associated with pulmonary edema in septic patients., Methods: We conducted a prospective cohort study in adult septic patients between October 2018 and May 2019. We performed repeated echocardiography and lung ultrasound examinations within the first 7 days after diagnosis of sepsis. We defined LVDD according to the 2016 recommendations of the American Society of Echocardiography and-for sensitivity analysis-according to an algorithm which has been validated in septic patients. We quantified pulmonary edema using the lung ultrasound score (LUSS), counting B-lines in four intercostal spaces., Results: We included 54 patients. LVDD was present in 51 (42%) of 122 echocardiography examinations. The mean (±SD) LUSS was 11 ± 6. There was no clinically meaningful association of LVDD with LUSS ( B = 0.55 [95%CI: -1.38; 2.47]; p = 0.571). Pneumonia was significantly associated with higher LUSS ( B = 4.42 [95%CI: 0.38; 8.5]; p = 0.033)., Conclusion: The lack of a clinically meaningful association of LVDD with LUSS suggests that LVDD is not a major contributor to pulmonary edema in septic patients., Trial Registration: NCT03768752, ClinicalTrials.gov, November 30 th , 2018 - retrospectively registered., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Kahl, Schirren, Yu, Lezius, Fischer, Menke, Sinning, Nierhaus, Vens, Zöllner, Kluge, Goepfert and Roeher.)

Background: Diabetes is associated with incidence and prevalence of Parkinson's disease (PD). Furthermore, glycated hemoglobin (HbA1c) levels have been linked with motor function and progression., Objectives: We evaluated the relationship between prevalent diabetes and HbA1c levels with serum neurofilament light chain (NfL) levels as marker of neuroaxonal damage., Methods: NfL concentrations were analyzed with Simoa in serum of 195 PD patients with available HbA1c values. Motor (MDS-UPDRS III, Hoehn & Yahr [H&Y]) and cognitive (Montreal Cognitive Assessment [MoCA]) function was assessed and vascular comorbidities were documented from medical records., Results: PD patients with prevalent diabetes had higher serum NfL levels and lower MoCA scores independent of age, body mass index (BMI), and vascular risk factors. Furthermore, diabetes was associated with higher H&Y stages in unadjusted and age/BMI-adjusted models. Higher HbA1c levels were associated with increased NfL in unadjusted and age/BMI-adjusted models., Conclusions: In PD patients, diabetes and high HbA1c are associated with increased neuroaxonal damage and cognitive impairment. © 2022 The Authors.

Purpose: The transcription factor Fra-2 affects the invasive potential of breast cancer cells by dysregulating adhesion molecules in vitro. Previous results suggested that it upregulates the expression of E- and P-selectin ligands. Such selectin ligands are important members of the leukocyte adhesion cascade, which govern the adhesion and transmigration of cancer cells into the stroma of the host organ of metastasis. As so far, no in vivo data are available, this study was designed to elucidate the role of Fra-2 expression in a spontaneous breast cancer metastasis xenograft model., Methods: The effect of Fra-2 overexpression in two stable Fra-2 overexpressing clones of the human breast cancer cell line MDA MB231 on survival and metastatic load was studied after subcutaneous injection into scid and E- and P-selectin-deficient scid mice., Results: Fra-2 overexpression leads to a significantly shorter overall survival and a higher amount of spontaneous lung metastases not only in scid mice, but also in E- and P-deficient mice, indicating that it regulates not only selectin ligands, but also selectin-independent adhesion processes., Conclusion: Thus, Fra-2 expression influences the metastatic potential of breast cancer cells by changing the expression of adhesion molecules, resulting in increased adherence to endothelial cells in a breast cancer xenograft model., (© 2021.

Background: Cardiogenic shock has a high mortality on optimal therapy. Adrenomedullin is released during cardiogenic shock and is involved in its pathophysiological processes. This study assessed treatment with the humanised, monoclonal, non-neutralising, adrenomedullin antibody adrecizumab, increasing circulating concentrations of adrenomedullin in cardiogenic shock., Methods: In this investigator-initiated, placebo-controlled, double-blind, multicentre, randomised trial (ACCOST-HH), patients were recruited from four university hospitals in Germany. Patients were eligible if they were 18 years old or older and hospitalised for cardiogenic shock within the last 48 h. Exclusion criteria were resuscitation for longer than 60 min and cardiogenic shock due to sustained ventricular tachycardia or bradycardia. Adult patients in cardiogenic shock were randomly assigned (1:1) to intravenous adrecizumab (8 mg/kg bodyweight) or placebo using an internet-based software. A block randomisation procedure was applied with stratification by age (older vs younger than 65 years), sex (male vs female), and type of underlying cardiogenic shock (acute myocardial infarction vs other entities). Investigators, patients, and medical staff involved in patient care were masked to group assignment. The primary endpoint was number of days up to day 30 without the need for cardiovascular organ support, defined as vasopressor therapy, inotropes, or mechanical circulatory support (or both) assessed in the intention-to-treat population. Safety outcomes included therapy-emergent serious adverse events, severe adverse events, adverse events, suspected unexpected serious adverse reactions, study drug-related mortality, and total mortality. The trial was registered at ClinicalTrials.gov, NCT03989531, and EudraCT, 2018-002824-17, and is now complete., Findings: Between April 5, 2019, and Jan 13, 2021, 150 patients were enrolled: 77 (51%) were randomly assigned to adrecizumab and 73 (49%) to placebo. All patients received the allocated treatment. The number of days without the need for cardiovascular organ support was not different between patients receiving adrecizumab or placebo (12·37 days [95% CI 9·80-14·94] vs 14·05 [11·41-16·69]; adjusted mean difference -1·69 days [-5·37 to 2·00]; p=0·37). Serious adverse events occurred in 59 patients receiving adrecizumab and in 57 receiving placebo (odds ratio 0·92 [95% CI 0·43-1·98]; p=0·83). Mortality was not different between groups at 30 days (hazard ratio 0·99 [95% CI 0·60-1·65]; p=0·98) or 90 days (1·10 [0·68-1·77]; p=0·71)., Interpretation: Adrecizumab was well tolerated in patients with cardiogenic shock but did not reduce the need for cardiovascular organ support or improve survival at days 30 and 90., Funding: Adrenomed AG and University Hospital of Hamburg., Competing Interests: Declaration of interests SK reports grants and non-financial support from Ambu, Daiichi Sankyo, ETView Ltd, Fisher & Paykel, Pfizer, and Xenios; personal fees from Astra, C R Bard, Baxter, Biotest, Cytosorbents, Daiichi Sankyo, Fresenius, Gilead, Mitsubishi Tanabe Pharma, MSD, Pfizer, Philips, Zoll, Bayer, Fresenius, Gilead, MSD and Pfizer, outside of the submitted work.

The PIGD (postural instability / gait difficulty) subtype of Parkinson´s disease (PD) is associated with faster cognitive and motor decline. So far, there are no quantifiable biomarkers to aid clinical subtyping. Neurofilament light chain (NfL) is a highly specific marker of neuro-axonal damage and can be assessed in blood. Here, we investigated if serum NfL concentrations are associated with PIGD subtype and PIGD scores in PD patients at advanced disease stages. Furthermore, we evaluated if serum NfL is associated with motor and cognitive function assessed with MDS-UPDRS part III and Montreal cognitive assessment (MoCA). Serum NfL levels were analyzed with Single Molecule Assays (Simoa) in blood of 223 PD patients from the bioMARKers in Parkinson's Disease (MARK-PD) study. Serum NfL concentrations were higher in PIGD patients independent of age, sex and disease duration. In linear regression analysis, serum NfL levels were associated with MoCA, MDS-UPDRS III and PIGD scores in unadjusted models, but remained significant after adjustment only with PIGD scores. In conclusion, increased serum NfL levels were associated with PIGD subtype and PIGD scores in patients with advanced PD., (© 2022. The Author(s).)

Background Pharmacists' interventions (PI) are suitable to improve medication safety and optimise patient outcome. However, in Germany, clinical pharmacy services are not yet available nationwide. Aim To gain prospective data on the extent and the composition of routine PI with special focus on intervention rates among German hospital pharmacists during two intervention weeks. Methods Within a repetitive cross-sectional study, clinical pharmacists documented all PIs on five days during a one-month period (intervention week) in 2017 and 2019 using the validated online-database ADKA-DokuPIK. Additionally, data regarding the supply structure/level of medical care, the extent of clinical pharmacy services and their professional experience were collected. All data were anonymised before analysis. Results In total, 2,282 PI from 62 pharmacists (2017) and 2578 PI from 52 pharmacists (2019) were entered. Intervention rate increased from 27.5 PI/100 patient days in 2017 to 38.5 PI/100 patient days in 2019 (p = 0.0097). Frequency of clinical pharmacy services on a daily basis significantly increased from 60% (2017) to 83% (2019). Reasons for PIs from the categories "drugs" (e.g. indication, choice, documentation/transcription) and "dose" were most common in both intervention weeks. The vast majority of underlying medication errors in both intervention weeks were categorised as "error, no harm" (80.3 vs. 78.6%), while the proportion of errors which did not reach the patient, doubled to 39.8% in IW-2019. Conclusion Regular and daily clinical pharmacy services become more established in Germany and clinical pharmacists are increasingly involved in solving drug related problems proactively and early during the medication management process., (© 2021.

Background and Purpose: Rapid access to acute stroke treatment improves clinical outcomes in patients with ischemic stroke. We aimed to shorten the time to admission and to acute stroke treatment for patients with acute stroke in the Hamburg metropolitan area by collaborative multilevel measures involving all hospitals with stroke units, the Emergency Medical Services (EMS), and health-care authorities., Methods: In 2007, an area-wide stroke care quality project was initiated. The project included mandatory admission of all stroke patients in Hamburg exclusively to hospitals with stroke units, harmonized acute treatment algorithms among all hospitals, repeated training of the EMS staff, a multimedia educational campaign, and a mandatory stroke care quality monitoring system based on structured data assessment and quality indicators for procedural measures. We analyzed data of all patients with acute stroke who received inhospital treatment in the city of Hamburg during the evaluation period from the quality assurance database data and evaluated trends of key quality indicators over time., Results: From 2007 to 2016, a total of 83,395 patients with acute stroke were registered. During this period, the proportion of patients admitted within ≤3 h from symptom onset increased over time from 27.8% in 2007 to 35.2% in 2016 (p < 0.001). The proportion of patients who received rapid thrombolysis (within ≤30 min after admission) increased from 7.7 to 54.1% (p < 0.001)., Conclusions: Collaborative stroke care quality projects are suitable and effective to improve acute stroke care., (© 2021 S.

Background: Treatment with sphingosine-1-phosphate (S1P) agonists confers neuroprotective effects in animal models of Parkinson's disease (PD)., Objectives: We assessed the association of serum S1P levels with motor and cognitive symptoms in patients with PD., Methods: S1P concentrations were analyzed with liquid chromatography-tandem mass spectrometry (LC-MS/MS) in serum of 196 PD patients and in 196 age- and sex-matched controls. Motor (Unified Parkinson's disease rating scale III [UPDRS III], Hoehn and Yahr) and cognitive (Montreal Cognitive Assessment [MoCA]) function were assessed at baseline. Follow-up data was available from 64 patients (median [interquartile range], 513 [381-677] days)., Results: S1P levels were lower in PD patients compared with controls, that is 1.75 (1.38-2.07) and 1.90 (1.59-2.18) μmol/L, respectively (P = 0.001). In PD patients, lower S1P concentrations were associated with higher UPDRS III scores and Hoehn and Yahr stage. In the follow-up cohort, S1P concentrations below the median were associated with faster motor decline (hazard ratio: 4.78 [95% CI, 1.98, 11.50]), but not with cognitive worsening., Conclusions: Our observations reveal an association of S1P with PD. © 2021 The Authors.

Introduction: Serum neurofilament light chain (NfL) levels are associated with disease severity in early Parkinson's disease (PD). We assessed the association of serum NfL with motor and cognitive function and decline in advanced PD patients., Methods: NfL concentrations were analyzed with single molecule array (Simoa) assay in serum of 289 PD patients with advanced disease from the single-center prospective observational biobank study Biomarkers in Parkinson's disease (MARK-PD). Motor and cognitive symptoms were assessed with MDS-UPDRS III, Hoehn&Yahr stages and Montreal Cognitive Assessment (MoCA) at baseline and during 520 [364, 674] days of follow-up., Results: Serum NfL concentrations were associated with Hoehn&Yahr stages. During follow-up, baseline NfL levels were associated with time to cognitive decline in adjusted Cox regression models (hazard ratio: 3.23; 95% CI [1.16, 9.00], P < 0.025). Serum NfL was associated with NT-proBNP in adjusted models linking neuronal and cardiac damage in advanced PD patients., Conclusion: In advanced PD patients, serum NfL concentrations are associated with motor function, cognitive decline and subclinical cardiac damage., (Copyright © 2021.

Purpose: Dysphagia is common in patients with Parkinson's disease (PD) and often leads to pneumonia, malnutrition, and reduced quality of life. This study investigates the ability of the Eating Assessment Tool-10 (EAT-10), an established, easy self-administered screening tool, to detect aspiration in PD patients. This study aims to validate the ability of the EAT-10 to detect FEES-proven aspiration in patients with PD., Methods: In a controlled prospective cross-sectional study, a total of 50 PD patients completed the EAT-10 and, subsequently, were examined by Flexible Endoscopic Evaluation of Swallowing (FEES) to determine the swallowing status. The results were rated through the Penetration-Aspiration Scale (PAS) and data were analyzed retrospectively., Results: PAS and EAT-10 did not correlate significantly. Selected items of the EAT-10 could not predict aspiration or residues. 19 (38%) out of 50 patients with either penetration or aspiration were not detected by the EAT-10. The diagnostic accuracy was established at only a sufficient level (AUC 0.65). An optimal cut-off value of ≥ 6 presented a sensitivity of 58% and specificity of 82%., Conclusions: The EAT-10 is not suited for the detection of penetration and aspiration in PD patients. Therefore, it cannot be used as a screening method in this patient population. There is still a need for a valid, simple, and efficient screening tool to assist physicians in their daily diagnostics and to avoid clinical complications.

Trimethyllysine (TML) is involved in the generation of the pro-atherogenic metabolite trimethylamine-N-oxide (TMAO) by gut microbiota. In clinical studies, elevated TML levels predicted major adverse cardiovascular events (MACE) in patients with acute or stable coronary artery disease (CAD). In contrast to cardiovascular patients, the role of TML in patients with acute cerebral ischemia is unknown. Here, we evaluated circulating TML levels in 374 stroke patients from the prospective biomarkers in stroke (MARK-STROKE) study. Compared with 167 matched healthy controls, acute ischemic stroke patients had lower median TML plasma concentrations, i.e. 0.71 vs. 0.47 µmol/L (p < 0.001) and this difference persisted after adjusting for age and sex. TML plasma concentrations were associated with age, serum creatinine, glucose, cholesterol and lysine. Patients with prevalent arterial hypertension, atrial fibrillation or a history of myocardial infarction had increased TML levels, but this observation was not independent of age, sex and GFR. In 274 patients, follow-up data were available. During a median follow-up of 284 [25th-75th percentile: 198, 431] days, TML was not associated with incident MACE (stroke, myocardial infarction, death). In summary, our data suggests a different role of TML in acute ischemic stroke compared with CAD patients.

Objectives: In prospective cohort studies different blood lipid fractions have been identified as risk factors of Parkinson's disease (PD). However, data relating lipoproteins to disease phenotypes and progression in advanced PD patients are sparse. Therefore, we assessed the most common lipoproteins in a case-control design and evaluated their associations with motor and cognitive function and decline in PD patients., Methods: Triglycerides, LDL-cholesterol (LDL-C), HDL-cholesterol (HDL-C), apolipoprotein A1 (ApoA1), apolipoprotein B (ApoB), and lipoprotein a (Lp(a)) were analyzed in 294 PD patients of the MARK-PD study cohort and 588 controls matched for age, sex and cardiovascular risk factors. In PD patients, motor (MDS-UPDRS III, Hoehn-Yahr stage) and cognitive function (MoCA) were examined. In a sub-cohort (n = 98 patients), baseline lipid levels were correlated with motor and cognitive disease progression during a follow-up period of 523 ± 199 days., Results: At baseline, HDL-C levels were lower in PD patients compared to matched controls after adjustment. We observed a very weak association of Lp(a) levels with UDPRS III scores. In cross-sectional analyses, no other lipid fraction revealed a significant and consistent association with motor or cognitive function. During follow-up, no lipid fraction level was associated with motor or cognitive progression., Conclusion: In advanced PD, there is no strong and consistent association of lipid levels with motor or cognitive function and decline., (Copyright © 2021 Elsevier Ltd.

S. epidermidis is a substantial component of the human skin microbiota, but also one of the major causes of nosocomial infection in the context of implanted medical devices. We here aimed to advance the understanding of S. epidermidis genotypes and phenotypes conducive to infection establishment. Furthermore, we investigate the adaptation of individual clonal lines to the infection lifestyle based on the detailed analysis of individual S. epidermidis populations of 23 patients suffering from prosthetic joint infection. Analysis of invasive and colonizing S. epidermidis provided evidence that invasive S. epidermidis are characterized by infection-supporting phenotypes (e.g. increased biofilm formation, growth in nutrient poor media and antibiotic resistance), as well as specific genetic traits. The discriminating gene loci were almost exclusively assigned to the mobilome. Here, in addition to IS256 and SCCmec, chromosomally integrated phages was identified for the first time. These phenotypic and genotypic features were more likely present in isolates belonging to sequence type (ST) 2. By comparing seven patient-matched nasal and invasive S. epidermidis isolates belonging to identical genetic lineages, infection-associated phenotypic and genotypic changes were documented. Besides increased biofilm production, the invasive isolates were characterized by better growth in nutrient-poor media and reduced hemolysis. By examining several colonies grown in parallel from each infection, evidence for genetic within-host population heterogeneity was obtained. Importantly, subpopulations carrying IS insertions in agrC, mutations in the acetate kinase (AckA) and deletions in the SCCmec element emerged in several infections. In summary, these results shed light on the multifactorial processes of infection adaptation and demonstrate how S. epidermidis is able to flexibly repurpose and edit factors important for colonization to facilitate survival in hostile infection environments., Competing Interests: The authors have declared that no competing interests exist.

Background Prospective longitudinal follow-up of left ventricular ejection fraction (LVEF) trajectories after acute cardiac decompensation of heart failure is lacking. We investigated changes in LVEF and covariates at 6-months' follow-up in patients with a predischarge LVEF ≤40%, and determined predictors and prognostic implications of LVEF changes through 18-months' follow-up. Methods and Results Interdisciplinary Network Heart Failure program participants (n=633) were categorized into subgroups based on LVEF at 6-months' follow-up: normalized LVEF (>50%; heart failure with normalized ejection fraction, n=147); midrange LVEF (41%-50%; heart failure with midrange ejection fraction, n=195), or persistently reduced LVEF (≤40%; heart failure with persistently reduced LVEF , n=291). All received guideline-directed medical therapies. At 6-months' follow-up, compared with patients with heart failure with persistently reduced LVEF, heart failure with normalized LVEF or heart failure with midrange LVEF subgroups showed greater reductions in LV end-diastolic/end-systolic diameters (both P <0.001), and left atrial systolic diameter ( P =0.002), more increased septal/posterior end-diastolic wall-thickness (both P <0.001), and significantly greater improvement in diastolic function, biomarkers, symptoms, and health status. Heart failure duration <1 year, female sex, higher predischarge blood pressure, and baseline LVEF were independent predictors of LVEF improvement. Mortality and event-free survival rates were lower in patients with heart failure with normalized LVEF ( P =0.002). Overall, LVEF increased further at 18-months' follow-up ( P <0.001), while LV end-diastolic diameter decreased ( P =0.048). However, LVEF worsened ( P =0.002) and LV end-diastolic diameter increased ( P =0.047) in patients with heart failure with normalized LVEF hospitalized between 6-months' follow-up and 18-months' follow-up. Conclusions Six-month survivors of acute cardiac decompensation for systolic heart failure showed variable LVEF trajectories, with >50% showing improvements by ≥1 LVEF category. LVEF changes correlated with various parameters, suggesting multilevel reverse remodeling, were predictable from several baseline characteristics, and were associated with clinical outcomes at 18-months' follow-up. Repeat hospitalizations were associated with attenuation of reverse remodeling. Registration URL: https://www.controlled-trials.com; Unique identifier: ISRCTN23325295.

Background: A variety of management options (e.g. immunotherapies, lifestyle interventions, and rehabilitation) are available for people with relapsing-remitting multiple sclerosis (RRMS). Besides coping with the diagnosis, people with MS (pwMS) have to make complex decisions such as deciding about immunotherapies. In addition to factual information, reports of patient experiences (PEx) may support patients in decision-making. The added value of PEx in decision-making is not clear, and controlled studies are rare. Therefore, systematic methods are necessary to develop and analyse PEx. As there are no evaluated PEx for MS in Germany, we are currently creating a website presenting PEx structured according to topics and illustrated by video, audio, and text files. We aim to determine the feasibility of an intervention using PEx and evaluate whether PEx may help pwMS in their immunotherapy decision-making processes as a supplement to evidence-based information., Methods: This project will follow the Medical Research Council framework for development and evaluation of complex interventions. After the development of a website with PEx, a randomised controlled pilot trial (pilot RCT) will be conducted in 2-3 MS centres, clinics, or rehabilitation centres including 55 pwMS and accompanied by a process evaluation. Patients with a RRMS diagnosis considering immunotherapy are eligible. The primary outcome is decision self-efficacy. Secondary outcomes include preparation for decision-making, decisional conflict, risk knowledge, confidence in active participation, affective forecasting, social support, and self-reported impact of eHealth on its users. Participants will be randomly assigned either to (i) an intervention group with 4 weeks access to an evidence-based patient information resource and the PExMS-website as an adjunct or to (ii) the control group with access to evidence-based information alone. A 6-member advisory panel involving representatives of pwMS, researchers, and neurologists, who accompany the whole project, will mentor this pilot RCT., Discussion: The intervention was developed with systematic methods, created with active patient involvement and in critical appraisal by an expert advisory panel. The study is innovative as it contributes to the controversial evidence on the use of PEx in the context of evidence-based patient information., Trial Registration: ClinicalTrials.gov, NCT04236544.

Purpose: Management of high-grade cervical intraepithelial neoplasia [CIN grade 2 or 3 (CIN2-3)] diagnosed during pregnancy is controversial. Monitoring with colposcopy and cytology every 8-12 weeks is advised by the most current guidelines., Study Design: This study analyzes the course of disease in pregnant women with abnormal cytologies or clinically suspicious cervixes., Results: In total, 139 pregnant women, at a median age of 31 years (range 19-49), treated at the Colposcopy Unit of the University Medical Center Hamburg-Eppendorf between 2011 and 2017 were identified. During pregnancy, at least one biopsy was performed on 70.5% of patients. In 84.7% of cases, CIN2-3 (CIN2 n = 14 (14.3%), CIN3 n = 69 (70.4%)) was detected, 7.1% (n = 7) of women were diagnosed with CIN1, while no dysplasia was found in 8.2% (n = 8) of cases. No interventions were necessary during pregnancy. Despite explicit invitation, only 72.3% of women with CIN2-3 attended postpartal consultations. While 61.7% showed persistent lesions, 5% were diagnosed with CIN1 and 33.3% with complete remission. During pregnancy, 68.7% of women with prepartal CIN2-3 were tested for HPV infection. Later, 49.1% were followed up postpartally by means of HPV testing and histology. HPV clearance was observed in 36.4% of women with complete histological remission. Postpartum conization was performed on 44.6% of patients with prepartal CIN2-3 diagnosis. CIN2-3 was histologically confirmed in 97.3% cases. Progression from persistent CIN3 to microinvasive carcinoma was observed in a single case., Conclusions: High-grade CIN lesions, diagnosed during pregnancy, show a high rate of regression postpartum; whereas, progression to carcinoma is rare. Close and continuous monitoring rarely has any therapeutic consequences. Compliance for postpartal follow-up needs to be improved.

The transmembrane protein claudin-1 is a major component of epidermal tight junctions (TJs), which create a dynamic paracellular barrier in the epidermis. Claudin-1 downregulation has been linked to atopic dermatitis (AD) pathogenesis but variable levels of claudin-1 have also been observed in healthy skin. To elucidate the impact of different levels of claudin-1 in healthy and diseased skin we determined claudin-1 levels in AD patients and controls and correlated them to TJ and skin barrier function. We observed a strikingly broad range of claudin-1 levels with stable TJ and overall skin barrier function in healthy and non-lesional skin. However, a significant decrease in TJ barrier function was detected in lesional AD skin where claudin-1 levels were further reduced. Investigations on reconstructed human epidermis expressing different levels of claudin-1 revealed that claudin-1 levels correlated with inside-out and outside-in barrier function, with a higher coherence for smaller molecular tracers. Claudin-1 decrease induced keratinocyte-autonomous IL-1β expression and fostered inflammatory epidermal responses to non-pathogenic Staphylococci. In conclusion, claudin-1 decrease beyond a threshold level results in TJ and epidermal barrier function impairment and induces inflammation in human epidermis. Increasing claudin-1 levels might improve barrier function and decrease inflammation and therefore be a target for AD treatment.

Background: Guanidino compounds, including asymmetric dimethylarginine (ADMA), symmetric dimethylarginine (SDMA), and L-homoarginine (hArg), have been associated with cardio- and cerebrovascular events and risk. We aimed to study if low hArg/ADMA and hArg/SDMA ratios are associated with mortality and outcome after stroke., Methods: In two prospective cohorts of acute stroke patients from Germany and the UK, we analyzed hArg, ADMA, and SDMA to determine hArg/ADMA and hArg/SDMA ratios. The guanidino compound levels were associated with mortality, adverse events, and neurological impairment, i.e., National Institutes of Health Stroke Scale (NIHSS) and modified Rankin Scale (mRS)., Results: During 7.4 years, high hArg/ADMA and hArg/SDMA ratios were both associated with a reduction in all-cause mortality in patients with ischemic stroke in a UK stroke cohort (hArg/ADMA: hazard ratio (HR) 0.75 [95% confidence interval (CI) 0.62-0.92]; n = 394; P = 0.006; hArg/SDMA: HR 0.68 [0.54-0.85]; n = 394; P = 0.001). In a German stroke cohort, patients with high hArg/SDMA ratio experienced fewer adverse events compared with those with low hArg/SDMA ratios within 30 days after stroke (HR 0.73 [0.57-0.92]; n = 135; P = 0.009), whereas hArg/ADMA was not predictive. Furthermore, hArg/SDMA ratios inversely correlated with the degree of neurological impairment (NIHSS) (r = - 0.27; P = 0.001; n = 138). Lower hArg/SDMA ratios were also found in dependent (mRS 3-6) compared with independent patients (mRS < 3; P = 0.007; n = 138), whereas hArg/ADMA did not., Conclusion: These results from two prospective stroke studies reveal that hArg/SDMA ratio could prove a valuable blood-based biomarker to discriminate patients with poor short- and long-term outcome, increased neurological impairment, and severe disability after stroke.

Background: The Telemedical Interventional Management in Heart Failure II (TIM-HF2) trial showed that, compared with usual care, a structured remote patient management (RPM) intervention done over 12-months reduced the percentage of days lost due to unplanned cardiovascular hospitalisations and all-cause death. The aim of the study was to evaluate whether this clinical benefit seen for the RPM group during the initial 12 month follow-up of the TIM-HF2 trial would be sustained 1 year after stopping the RPM intervention., Methods: TIM-HF2 was a prospective, randomised, multicentre trial done in 43 hospitals, 60 cardiology practices, and 87 general practitioners in Germany. Patients with heart failure, New York Heart Association functional class II or III, and who had been hospitalised for heart failure within 12 months before randomisation were randomly assigned to either the RPM intervention or usual care. At the final study visit (main trial), the RPM intervention was stopped and the 1 year extended follow-up period started, which lasted 1 year. The primary outcome was percentage of days lost due to unplanned cardiovascular hospitalisations and all-cause mortality. Analyses were done using the intention-to-treat principle. This trial is registered with ClinicalTrials.gov, number NCT01878630., Findings: Between Aug 13, 2013, and May 12, 2017, 1538 patients were enrolled (765 to the remote patient management group and 773 to the usual care group) in the main trial. 671 of 765 patients in the remote patient management group and 673 of 773 in the usual care group completed the main trial and started the extended follow-up period up to 1 year later. In the extended follow-up period, the percentage of days lost due to unplanned cardiovascular hospital admissions and all-cause mortality did not differ significantly between groups weighted mean 5·95% [95% CI 4·59-7·31] in the RPM group vs 6·64% [95% CI 5·19-8·08] in the usual care group [rate ratio 0·79; 95% CI 0·78-1·21]). However, when data from the main trial and the extended follow-up period were combined, the percentage of days lost due to unplanned cardiovascular hospitalisation or all-cause death was significantly less in patients allocated to the RPM group (382 [50%] of 765; weighted mean 9·28%; 95% CI 7·76-10·81) than in the UC group (398 [51%] of 773; 11·78%; 95% CI 10·08-13·49; ratio of weighted average 0·79; 95% CI 0·62-1·00; p=0·0486)., Interpretation: The positive effect of our RPM intervention on morbidity and mortality over the course of the main trial was no longer observed 1 year after stopping the RPM intervention. However, because the TIM-HF2 trial was not powered to show significance during the extended follow-up period, our results are exploratory and require further research., Funding: German Federal Ministry of Education and Research., (Copyright © 2020 The Author(s).

Objectives: Mucopolysaccharidosis type I (MPS I) is an inherited lysosomal storage disorder characterized by severe multi-systemic organ manifestations including obstructive sleep apnea syndrome (OSAS). Hematopoietic stem cell transplantation (HSCT) is the treatment of choice in severe MPS I (MPS IH, Hurler syndrome). However, the effect of HSCT on OSAS in MPS IH still remains unclear. The purpose of this study was to analyze respiratory patterns during sleep following HSCT in MPS IH children and to relate these findings to craniofacial abnormalities., Methods: Overnight polysomnographies of nine MPS IH children (mean age: 8.2 years) previously treated with HSCT were retrospectively analyzed. Magnetic resonance images of the head were assessed with regard to soft and hard tissue abnormalities of the upper respiratory tract., Results: The mean apnea hypopnea index (AHI) was 5.3 events/h (range, 0.3-12.2), and the majority of apnea/hypopneas were obstructive. Whereas two patients had severe OSAS (AHI > 10) and two moderate OSAS (5 > AHI < 10), five patients had no evidence of OSAS (AHI < 2.0). Donor cell chimerism was significantly lower in MPS IH patients with OSAS as compared to patients without OSAS (p < 0.001). The upper airway space and the maxilla were significantly smaller and the adenoids larger in MPS IH patients with OSAS as compared to those of non-OSAS patients., Conclusion: OSAS was only observed in MPS IH patients with graft failure or low donor cell chimerism. Conversely, successful HSCT seems to ameliorate adenoid hyperplasia and maxillary constriction in MPS IH patients and thereby minimizes the risk of OSAS at least at younger ages.

Introduction: Guanidino compounds, including l-homoarginine (l-hArg), symmetric dimethylarginine (SDMA), asymmetric dimethylarginine (ADMA) and l-arginine (l-Arg) are associated with mortality, fatal strokes, stroke incidence, and atherosclerosis., Objectives: We aimed to study the association of guanidino compounds (l-hArg/ADMA and l-hArg/SDMA) with stroke etiology, internal carotid artery (ICA) stenosis and CHA 2 DS 2 -VASc score in patients with cerebrovascular disease., Methods: We analyzed l-hArg, SDMA, ADMA, l-Arg, and compound molar ratios, i.e. l-hArg/ADMA and l-hArg/SDMA, in 272 patients with cerebrovascular disease in a cross-sectional discovery cohort and two cross-sectional validation cohorts of acute stroke patients from Germany (n = 137) and UK (n = 394). The guanidino compound levels were compared with clinical, imaging, and ultrasound parameters., Results: Low l-hArg/ADMA and l-hArg/SDMA molar ratios predicted territorial infarcts (OR 1.74; 95% CI 1.34-2.26 and OR 1.64; 95% CI 1.26-2.15, respectively) and were associated with stroke subtypes due to large vessel disease or cardio-embolism (OR 1.52; 95% CI 1.12-2.06 and OR 2.01; 95% CI 1.35-3.00, respectively) in meta-analysis of the discovery and validation cohort data. In line with these results, a low l-hArg/ADMA and l-hArg/SDMA molar ratio was found in patients with ICA stenosis (OR 0.73; 95% CI 0.55-0.97 and OR 0.69; 95% CI 0.50-0.94, respectively) in the discovery and validation cohort. Furthermore, guanidino compound ratios (i.e. l-hArg/ADMA and l-hArg/SDMA) were strongly correlated with CHA 2 DS 2 -VASC score (p < .001) in all three cohorts., Discussion: The results from these three cross-sectional studies reveal that guanidino compound ratios (i.e. l-hArg/ADMA and l-hArg/SDMA) can discriminate stroke etiologies, predict ICA stenosis and estimate risk prediction in patients with cerebrovascular disease., (Copyright © 2019 Elsevier B.V.

Background: Nitric oxide (NO) regulates processes involved in sepsis progression, including vascular and immune function. NO is generated by nitric oxide synthases (NOS) from L-arginine. Cellular L-arginine uptake is inhibited by symmetric dimethylarginine (SDMA) and asymmetric dimethylarginine (ADMA) is a competitive inhibitor of NOS. Increased inhibitor blood concentrations lead to reduce NO bioavailability. The aim of this study was to determine whether plasma concentrations of SDMA and ADMA are markers for sepsis survival., Method: This prospective, single center study involved 120 ICU patients with sepsis. Plasma SDMA and ADMA were measured on admission (day 1), day 3 and day 7 by mass spectrometry together with other laboratory markers. The sequential organ failure assessment (SOFA) score was used to evaluate sepsis severity. Survival was documented until day 28. Groups were compared using the Mann-Whitney U test, chi-squared test or non-parametric analysis of variance (ANOVA). Mortality was assessed using Kaplan-Meier curves and compared using the log-rank test. Specific risk groups were identified using a decision tree algorithm., Results: Median plasma SDMA and ADMA levels were significantly higher in non-survivors than in survivors of sepsis: SDMA 1.14 vs. 0.82 μmol/L (P = 0.002) and ADMA 0.93 vs. 0.73 μmol/L (P = 0.016). ANOVA showed that increased plasma SDMA and ADMA concentrations were significantly associated with SOFA scores. The 28-day mortality was compared by chi-square test: for SDMA the mortality was 12% in the lower, 25% in the intermediate and 43% in the 75th percentile (P = 0.018); for ADMA the mortality was 18-20% in the lower and intermediate but 48% in the 75th percentile (P = 0.006). The highest mortality (61%) was found in patients with plasma SDMA > 1.34 together with ADMA levels > 0.97 μmol/L., Conclusions: Increased plasma concentrations of SDMA and ADMA are associated with sepsis severity. Therefore, our findings suggest reduced NO bioavailability in non-survivors of sepsis. One may use individual SDMA and ADMA levels to identify patients at risk. In view of the pathophysiological role of NO we conclude that the vascular system and immune response are most severely affected when SDMA and ADMA levels are high.

Background: Fabry disease (FD) is characterized by early development of vasculopathy and endothelial dysfunction. However, it is unclear whether these findings also play a pivotal role in cardiac manifestation. As Fabry cardiomyopathy (FC) is the leading cause of death in FD, we aimed to gather a better insight in pathological mechanisms of the disease. Methods: Serum samples were obtained from 17 healthy controls, 15 FD patients with and 7 without FC. FC was defined by LV wall thickening of >12 mm in cardiac magnetic resonance imaging and serum level of proBNP, high sensitive Troponin T (hsT), and globotriaosylsphingosine (lyso-GB3) were obtained. A multiplex ELISA-Assay for 23 different angiogenesis markers was performed in pooled samples. Markers showing significant differences among groups were further analyzed in single samples using specific Elisa antibody assays. L-homoarginine (hArg), L-arginine, asymmetric (ADMA), and symmetric Dimethylarginine (SDMA) were quantified by liquid chromatography-mass spectrometry. Results: Angiostatin and matrix metalloproteinase 9 (MMP-9) were elevated in FD patients compared to controls independently of the presence of FC (angiostatin: 98 ± 25 vs. 75 ± 15 ng/mL; p = 0.001; MMP-9: 8.0 ± 3.4 vs. 5.0 ± 2.4 μg/mL; p = 0.002). SDMA concentrations were highest in patients with FC (0.90 ± 0.64 μmol/l) compared to patients without (0.57 ± 0.10 μmol/l; p = 0.027) and vs. controls (0.58 ± 0.12 μmol/l; p = 0.006) and was positively correlated with indexed LV-mass ( r = 0.61; p = 0.003), hsT ( r = 0.56, p = 0.008), and lyso-Gb3 ( r = 0.53, p = 0.013). Accordingly, the ratio of L-homoarginine to SDMA (hArg/SDMA) was lowest in patients with FC (2.63 ± 1.78) compared to controls (4.16 ± 1.44; p = 0.005). For L-arginine, hArg and ADMA no significant differences among groups could be detected, although a trend toward higher ADMA and lower hArg levels could be observed in the FC group. Furthermore, a significant relationship between kidney and cardiac function could be revealed ( p = 0.045). Conclusion: Elevated MMP-9 and angiostatin levels suggest an increased extracellular matrix turnover in FD patients. Furthermore, endothelial dysfunction may also be involved in FC, as SDMA and hArg/SDMA are altered in these patients.
