The inodilator levosimendan, in clinical use for over two decades, has been the subject of extensive clinical and experimental evaluation in various clinical settings beyond its principal indication in the management of acutely decompensated chronic heart failure. Critical care and emergency medicine applications for levosimendan have included postoperative settings, septic shock, and cardiogenic shock. As the experience in these areas continues to expand, an international task force of experts from 15 countries (Austria, Belgium, China, Croatia, Finland, France, Germany, Greece, Hungary, Italy, the Netherlands, Spain, Sweden, Switzerland, and the USA) reviewed and appraised the latest additions to the database of levosimendan use in critical care, considering all the clinical studies, meta-analyses, and guidelines published from September 2019 to November 2021. Overall, the authors of this opinion paper give levosimendan a “should be considered” recommendation in critical care and emergency medicine settings, with different levels of evidence in postoperative settings, septic shock, weaning from mechanical ventilation, weaning from veno-arterial extracorporeal membrane oxygenation, cardiogenic shock, and Takotsubo syndrome, in all cases when an inodilator is needed to restore acute severely reduced left or right ventricular ejection fraction and overall haemodynamic balance, and also in the presence of renal dysfunction/failure.
Background Early detection of delirium through systematic screening is essential to mitigate and prevent possible consequences. The 4 'A's Test (4AT) is a new tool that can be used for delirium detection easily and without special training. The modified Confusion Assessment Method for Emergency Department (mCAM-ED) is an operationalized version of the Confusion Assessment Method, a worldwide used tool for delirium screening in clinical practice and research. This is the first comparison of both delirium screening tools. This study aimed to investigate performance accuracy of the 4AT compared to the mCAM-ED in detecting delirium in hospitalized patients. Methods In this prospective single-centre cross-sectional pilot study, patients from six wards were selected consecutively. All patients underwent a delirium screening with the gold standard, the mCAM-ED. To rate the algorithm of the 4AT, corresponding items of the mCAM-ED were derived and used. Results A total of 116 patients with a median age of 73 years could be included. Dementia was present in 11 (9.5%) patients, and 42.2% were women. Delirium was present in 8/116 (6.9%) and 16/116 (13.8%) patients according to the mCAM-ED and the 4AT, respectively. In comparison, the 4AT showed 100% (95% CI 0.63, 1.00) sensitivity, 93% (95% CI 0.86, 0.97) specificity, 13.50 (95% CI 6.93, 26.30) positive likelihood ratio and 0.00 (95% CI 0.00, NaN) negative likelihood ratio. Conclusions In this first comparison, the 4AT showed a high rate of false-positive scores, which may result in an increased need for further in-depth assessments.
Abstract Background Medical emergencies are complex and stressful, especially for the young and inexperienced. Cognitive aids (CA) have been shown to facilitate management of simulated medical emergencies by experienced teams. In this randomized trial we evaluated guideline adherence and treatment efficacy in simulated medical emergencies managed by residents with and without CA. Methods Physicians attending educational courses executed simulated medical emergencies. Teams were randomly assigned to manage emergencies with or without CA. Primary outcome was risk reduction of essential working steps. Secondary outcomes included prior experience in emergency medicine and CA, perceptions of usefulness, clinical relevance, acceptability, and accuracy in CA selection. Participants were grouped as “medical” (internal medicine and neurology) and “perioperative” (anesthesia and surgery) regarding their specialty. The study was designed as a prospective randomized single-blind study that was approved by the ethical committee of the University Duisburg-Essen (19-8966-BO). Trial registration: DRKS, DRKS00024781. Registered 16 March 2021—Retrospectively registered, http://www.drks.de/DRKS00024781 . Results Eighty teams participated in 240 simulated medical emergencies. Cognitive aid usage led to 9% absolute and 15% relative risk reduction. Per protocol analysis showed 17% absolute and 28% relative risk reduction. Wrong CA were used in 4%. Cognitive aids were judged as helpful by 94% of the participants. Teams performed significantly better when emergency CA were available (p
Congenital myopathies (CM) are a group of early-onset, genetically diverse muscle disorders of variable severity with characteristic muscle biopsy findings. Mutations in RYR1, the gene encoding the RYR1, are the most common genetic cause, responsible for ∼30% of all human CM. They are linked to the pharmacogenetic disorder malignant hyperthermia susceptibility and to various disease phenotypes, including central core disease (which is primarily dominantly inherited), multiminicore disease (which is predominantly recessively inherited), some forms of centronuclear myopathy and congenital fiber-type disproportion (which can be either dominantly or recessively inherited), and King–Denborough syndrome (a CM characterized by skeletal abnormalities, dysmorphic features, and malignant hyperthermia susceptibility). The recessive forms of RYR1-linked CM are more severe, affecting children at birth and, in addition to profound muscle weakness, may also affect facial and extraocular muscles and cause skeletal deformities and feeding difficulties. To study the mechanism leading to the profound muscle weakness characterized by recessive RYR1-CM, we created transgenic mice knocked in for the compound heterozygous RYR1 p.Q1970fsX16+p.A4329D mutations (double knock-in mouse, or DKI) identified in a severely affected child. The in vivo and ex vivo physiological functions of fast twitch, slow twitch, and extraocular muscles were severely impaired in DKI mice; in addition, the mutations were accompanied by a >50% decrease in RYR1 protein in all muscles examined, as well as changes in the expression of many proteins important for muscle function and chromatin structure. Muscle ultrastructure was disorganized, with fewer CRU and mitochondria and presence of cores. MyHC-EO, the superfast and ocular-muscle−specific myosin heavy isoform, was almost undetectable in EOMs from DKI mutant mice. Thus, the DKI mouse model faithfully recapitulates the human disease and could be exploited for preclinical studies aimed at developing therapeutic strategies to treat neuromuscular disorders linked to recessive RYR1 mutations.
Background Venous thromboembolism (VTE) contributes significantly to COVID‐19 morbidity and mortality. The urokinase receptor system is involved in the regulation of coagulation. Levels of soluble urokinase plasminogen activator receptor (suPAR) reflect hyperinflammation and are strongly predictive of outcomes in COVID‐19. Whether suPAR levels identify patients with COVID‐19 at risk for VTE is unclear. Methods and Results We leveraged a multinational observational study of patients hospitalized for COVID‐19 with suPAR and D‐dimer levels measured on admission. In 1960 patients (mean age, 58 years; 57% men; 20% Black race), we assessed the association between suPAR and incident VTE (defined as pulmonary embolism or deep vein thrombosis) using logistic regression and Fine‐Gray modeling, accounting for the competing risk of death. VTE occurred in 163 (8%) patients and was associated with higher suPAR and D‐dimer levels. There was a positive association between suPAR and D‐dimer (β=7.34; P =0.002). Adjusted for clinical covariables, including D‐dimer, the odds of VTE were 168% higher comparing the third with first suPAR tertiles (adjusted odds ratio, 2.68 [95% CI, 1.51–4.75]; P <0.001). Findings were consistent when stratified by D‐dimer levels and in survival analysis accounting for death as a competing risk. On the basis of predicted probabilities from random forest, a decision tree found the combined D‐dimer <1 mg/L and suPAR <11 ng/mL cutoffs, identifying 41% of patients with only 3.6% VTE probability. Conclusions Higher suPAR was associated with incident VTE independently of D‐dimer in patients hospitalized for COVID‐19. Combining suPAR and D‐dimer identified patients at low VTE risk.

Rationale: Coronavirus disease 2019 (COVID-19) can lead to acute respiratory distress syndrome with fatal outcomes. Evidence suggests that dysregulated immune responses, including autoimmunity, are key pathogenic factors. Objectives: To assess whether IgA autoantibodies target lung-specific proteins and contribute to disease severity. Methods: We collected 147 blood, 9 lung tissue, and 36 bronchoalveolar lavage fluid samples from three tertiary hospitals in Switzerland and one in Germany. Severe COVID-19 was defined by the need to administer oxygen. We investigated the presence of IgA autoantibodies and their effects on pulmonary surfactant in COVID-19 using the following methods: immunofluorescence on tissue samples, immunoprecipitations followed by mass spectrometry on bronchoalveolar lavage fluid samples, enzyme-linked immunosorbent assays on blood samples, and surface tension measurements with medical surfactant. Measurements and main results: IgA autoantibodies targeting pulmonary surfactant proteins B and C were elevated in patients with severe COVID-19, but not in patients with influenza or bacterial pneumonia. Notably, pulmonary surfactant failed to reduce surface tension after incubation with either plasma or purified IgA from patients with severe COVID-19. Conclusions: Our data suggest that patients with severe COVID-19 harbor IgA against pulmonary surfactant proteins B and C and that these antibodies block the function of lung surfactant, potentially contributing to alveolar collapse and poor oxygenation.

Background: The exact location of skin lesions is key in clinical dermatology. On one hand, it supports differential diagnosis (DD) since most skin conditions have specific predilection sites. On the other hand, location matters for dermatosurgical interventions. In practice, lesion evaluation is not well standardized and anatomical descriptions vary or lack altogether. Automated determination of anatomical location could benefit both situations. Objective: Establish an automated method to determine anatomical regions in clinical patient pictures and evaluate the gain in DD performance of a deep learning model (DLM) when trained with lesion locations and images. Methods: Retrospective study based on three datasets: macro-anatomy for the main body regions with 6000 patient pictures partially labeled by a student, micro-anatomy for the ear region with 182 pictures labeled by a student and DD with 3347 pictures of 16 diseases determined by dermatologists in clinical settings. For each dataset a DLM was trained and evaluated on an independent test set. The primary outcome measures were the precision and sensitivity with 95% CI. For DD, we compared the performance of a DLM trained with lesion pictures only with a DLM trained with both pictures and locations. Results: The average precision and sensitivity were 85% (CI 84-86), 84% (CI 83-85) for macro-anatomy, 81% (CI 80-83), 80% (CI 77-83) for micro-anatomy and 82% (CI 78-85), 81% (CI 77-84) for DD. We observed an improvement in DD performance of 6% (McNemar test p-value 0.0009) for both average precision and sensitivity when training with both lesion pictures and locations. Conclusion: Including location can be beneficial for DD DLM performance. The proposed method can generate body region maps from patient pictures and even reach surgery relevant anatomical precision for e.g. the ear region. Our method enables automated search of large clinical databases and make targeted anatomical image retrieval possible.
Background Post-mortem imaging has been suggested as an alternative to conventional autopsy in the prenatal and postnatal periods. Noninvasive autopsies do not provide tissue for histological examination, which may limit their clinical value, especially when infection-related morbidity and mortality are suspected. Methods We performed a prospective, multicentre, cross-sectional study to compare the diagnostic performance of post-mortem magnetic resonance imaging with computed tomography-guided biopsy (Virtopsy®) with that of conventional autopsy in foetuses and infants. Cases referred for conventional autopsy were eligible for enrolment. After post-mortem imaging using a computed tomography scanner and a magnetic resonance imaging unit, computed tomography-guided tissue sampling was performed. Virtopsy results were compared with conventional autopsy in determining the likely final cause of death and major pathologies. The primary outcome was the proportion of cases for which the same cause of death was determined by both methods. Secondary outcomes included the proportion of false positive and false negative major pathological lesions detected by virtopsy and the proportion of computed tomography-guided biopsies that were adequate for histological examination. Results Overall, 101 cases (84 fetuses, 17 infants) were included. Virtopsy and autopsy identified the same cause of death in 91 cases (90.1%, 95% CI 82.7 to 94.5). The sensitivity and specificity of virtopsy for determining the cause of death were 96.6% (95% CI 90.6 to 98.8) and 41.7% (95% CI 19.3 to 68.0), respectively. In 32 cases (31.7%, 95% CI 23.4 to 41.3), major pathological findings remained undetected by virtopsy, and in 45 cases (44.6%, 95% CI 35.2 to 54.3), abnormalities were diagnosed by virtopsy but not confirmed by autopsy. Computed tomography-guided tissue sampling was adequate for pathological comments in 506 of 956 biopsies (52.7%) and added important diagnostic value in five of 30 cases (16.1%) with an unclear cause of death before autopsy compared with postmortem imaging alone. In 19 of 20 infective deaths (95%), biopsies revealed infection-related tissue changes. Infection was confirmed by placental examination in all fetal cases. Conclusions Virtopsy demonstrated a high concordance with conventional autopsy for the detection of cause of death but was less accurate for the evaluation of major pathologies. Computed tomography-guided biopsy had limited additional diagnostic value. Trial registration ClinicalTrials.gov (NCT01888380).
The complement system is a field of growing interest for pharmacological intervention. Complement protein C1q, the pattern recognition molecule at the start of the classical pathway of the complement cascade, is a versatile molecule with additional non-canonical actions affecting numerous cellular processes. Based on observations made in patients with hereditary C1q deficiency, C1q is protective against systemic autoimmunity and bacterial infections. Accordingly, C1q deficient mice reproduce this phenotype with susceptibility to autoimmunity and infections. At the same time, beneficial effects of C1q deficiency on disease entities such as neurodegenerative diseases have also been described in murine disease models. This systematic review provides an overview of all currently available literature on the C1q knockout mouse in disease models to identify potential target diseases for treatment strategies focusing on C1q, and discusses potential side-effects when depleting and/or inhibiting C1q.
Purpose of Review To provide a comprehensive review of drugs and neoplastic, infectious, autoinflammatory, and immunodeficiency diseases causing medium- to large-vessel vasculitis in adults with emphasis on information essential for the initial diagnostic process. Recent Findings Entities with medium- to large-vessel vasculitis as clinical manifestations have been described recently (e.g., adenosine deaminase-2 deficiency, VEXAS-Syndrome), and vasculitis in established autoinflammatory or immunodeficiency diseases is increasingly being identified. Summary In the diagnostic process of medium- to large-vessel vasculitis in adults, a large variety of rare diseases should be included in the differential diagnosis, especially if diagnosis is made without histologic confirmation and in younger patients. Although these disorders should be considered, they will undoubtedly remain rare in daily practice.
Aortic dimensions and distensibility are key risk factors for aortic aneurysms and dissections, as well as for other cardiovascular and cerebrovascular diseases. We present genome-wide associations of ascending and descending aortic distensibility and area derived from cardiac magnetic resonance imaging (MRI) data of up to 32,590 Caucasian individuals in UK Biobank. We identify 102 loci (including 27 novel associations) tagging genes related to cardiovascular development, extracellular matrix production, smooth muscle cell contraction and heritable aortic diseases. Functional analyses highlight four signalling pathways associated with aortic distensibility (TGF-β, IGF, VEGF and PDGF). We identify distinct sex-specific associations with aortic traits. We develop co-expression networks associated with aortic traits and apply phenome-wide Mendelian randomization (MR-PheWAS), generating evidence for a causal role for aortic distensibility in development of aortic aneurysms. Multivariable MR suggests a causal relationship between aortic distensibility and cerebral white matter hyperintensities, mechanistically linking aortic traits and brain small vessel disease. Aortic distensibility is a risk factor for multiple cardiovascular events, but the genetic etiology is not well understood. Here, the authors identify genetic variants linked to aortic distensibility, highlighting mechanistic pathways and causal relationships between distensibility and both aortic aneurysms and brain small vessel disease.
Preliminary data and clinical experience have suggested an increased risk of abnormal uterine bleeding (AUB) in women of reproductive age treated with anticoagulants, but solid data are lacking. The TEAM-VTE study was an international, multicentre, prospective cohort study in women aged 18-50 diagnosed with acute venous thromboembolism (VTE). Menstrual blood loss was measured by Pictorial Blood Loss Assessment Charts (PBAC) at baseline for the last menstrual cycle before VTE diagnosis and prospectively for each cycle during three-six month follow-up. AUB was defined as an elevated PBAC score (>100 or >150) or self-reported AUB. AUB-related quality of life (QoL) was assessed at baseline and end of follow-up using the Menstrual Bleeding Questionnaire (MBQ). The study was terminated early because of slow recruitment due to the pandemic. Of the 98 women, 65 (66%) met at least one of the three definitions of AUB during follow-up (95% confidence interval (CI) 57-75%). AUB occurred in 60% (36/60) of women without AUB before VTE diagnosis ('new-onset' AUB; 95%CI 47-71%). Overall, QoL decreased over time with a mean MBQ increase of 5.1 points (95%CI 2.2-7.9), but this decrease in QoL was only observed among women with new-onset AUB. To conclude, two out of three women who start anticoagulation for acute VTE suffer from AUB, with a considerable negative impact on QoL. These findings should be a call to action to increase awareness and provide evidence-based strategies for preventing and treating AUB in this setting. This was an academic study (NCT04748393 at www.clinicaltrials.gov); no funding was received.
Cynomolgus monkeys exhibit human-like features, such as a fovea, so they are often used in non-clinical research. Nevertheless, little is known about the natural variation of the choroidal thickness in relation to origin and sex. A combination of deep learning and a deterministic computer vision algorithm was applied for automatic segmentation of foveolar optical coherence tomography images in cynomolgus monkeys. The main evaluation parameters were choroidal thickness and surface area directed from the deepest point on OCT images within the fovea, marked as the nulla with regard to sex and origin. Reference choroid landmarks were set underneath the nulla and at 500 µm intervals laterally up to a distance of 2000 µm nasally and temporally, complemented by a sub-analysis of the central bouquet of cones. 203 animals contributed 374 eyes for a reference choroid database. The overall average central choroidal thickness was 193 µm with a coefficient of variation of 7.8%, and the overall mean surface area of the central bouquet temporally was 19,335 µm² and nasally was 19,283 µm². The choroidal thickness of the fovea appears relatively homogeneous between the sexes and the studied origins. However, considerable natural variation has been observed, which needs to be appreciated.
Objectives: Systemic lupus erythematosus (SLE) is a clinically heterogeneous autoimmune disease with complex pathogenic mechanisms. Complement C1q has been shown to play a major role in SLE, and autoantibodies against C1q (anti-C1q) are strongly associated with SLE disease activity and severe lupus nephritis suggesting a pathogenic role for anti-C1q. Whereas C1q alone has anti-inflammatory effects on human monocytes and macrophages, C1q/anti-C1q complexes favor a pro-inflammatory phenotype. This study aimed to elucidate the inflammatory effects of anti-C1q on peripheral blood mononuclear cells (PBMCs). Methods: Isolated monocytes, isolated T cells and bulk PBMCs of healthy donors with or without concomitant T cell activation were exposed to C1q or complexes of C1q and SLE patient-derived anti-C1q (C1q/anti-C1q). Functional consequences of C1q/anti-C1q on cells were assessed by determining cytokine secretion, monocyte surface marker expression, T cell activation and proliferation. Results: Exposure of isolated T cells to C1q or C1q/anti-C1q did not affect their activation and proliferation. However, unspecific T cell activation in PBMCs in the presence of C1q/anti-C1q resulted in increased TNF, IFN-γ and IL-10 secretion compared with C1q alone. Co-culture and inhibition experiments showed that the inflammatory effect of C1q/anti-C1q on PBMCs was due to a direct CD40-CD154 interaction between activated T cells and C1q/anti-C1q-primed monocytes. The CD40-mediated inflammatory reaction of monocytes involves TRAF6 and JAK3-STAT5 signalling. Conclusion: In conclusion, C1q/anti-C1q have a pro-inflammatory effect on monocytes that depends on T cell activation and CD40-CD154 signalling. This signalling pathway could serve as a therapeutic target for anti-C1q-mediated inflammation.
Background: Endovascular thrombectomy (EVT) is the standard-of-care for proximal large vessel occlusion (LVO) stroke. Data on technical and clinical outcomes in distal vessel occlusions (DVOs) remain limited. Methods: This was a retrospective study of patients undergoing EVT for stroke at 32 international centers. Patients were divided into LVOs (internal carotid artery/M1/vertebrobasilar), medium vessel occlusions (M2/A1/P1) and isolated DVOs (M3/M4/A2/A3/P2/P3) and categorized by thrombectomy technique. Primary outcome was a good functional outcome (modified Rankin Scale ≤2) at 90 days. Secondary outcomes included recanalization, procedure-time, thrombectomy attempts, hemorrhage, and mortality. Multivariate logistic regressions were used to evaluate the impact of technical variables. Propensity score matching was used to compare outcome in patients with DVO treated with aspiration versus stent retriever RESULTS: We included 7477 patients including 213 DVOs. Distal location did not independently predict good functional outcome at 90 days compared with proximal (p=0.467). In distal occlusions, successful recanalization was an independent predictor of good outcome (adjusted odds ratio (aOR) 5.11, p<0.05) irrespective of technique. Younger age, bridging therapy, and lower admission National Institutes of Health Stroke Scale (NIHSS) were also predictors of good outcome. Procedure time ≤1 hour or ≤3 thrombectomy attempts were independent predictors of good outcomes in DVOs irrespective of technique (aOR 4.5 and 2.3, respectively, p<0.05). There were no differences in outcomes in a DVO matched cohort of aspiration versus stent retriever. Rates of hemorrhage and good outcome showed an exponential relationship to procedural metrics, and were more dependent on time in the aspiration group and attempts in the stent retriever group. Conclusions: Outcomes following EVT for DVO are comparable to LVO with similar results between techniques. Techniques may exhibit different futility metrics; stent retriever thrombectomy was influenced by attempts whereas aspiration was more dependent on procedure time.
Cerebellar symptoms in multiple sclerosis (MS) are well described; however, the exact contribution of cerebellar damage to MS disability has not been fully explored. Longer-term observational periods are necessary to better understand the dynamics of pathological changes within the cerebellum and their clinical consequences. Cerebellar lobe and single lobule volumes were automatically segmented on 664 3D-T1-weighted MPRAGE scans (acquired at a single 1.5 T scanner) of 163 MS patients (111 women; mean age: 47.1 years; 125 relapsing–remitting (RR) and 38 secondary progressive (SP) MS, median EDSS: 3.0) imaged annually over 4 years. Clinical scores (EDSS, 9HPT, 25FWT, PASAT, SDMT) were determined per patient per year with a maximum clinical follow-up of 11 years. Linear mixed-effect models were applied to assess the association between cerebellar volumes and clinical scores and whether cerebellar atrophy measures may predict future disability progression. SPMS patients exhibited faster posterior superior lobe volume loss over time compared to RRMS, which was related to increase of EDSS over time. In RRMS, cerebellar volumes were significant predictors of motor scores (e.g. average EDSS, T25FWT and 9HPT) and SDMT. Atrophy of motor-associated lobules (IV-VI + VIII) was a significant predictor of future deterioration of the 9HPT of the non-dominant hand. In SPMS, the atrophy rate of the posterior superior lobe (VI + Crus I) was a significant predictor of future PASAT performance deterioration. Regional cerebellar volume reduction is associated with motor and cognitive disability in MS and may serve as a predictor for future disease progression, especially of dexterity and impaired processing speed.
Background Robotic-assisted colorectal surgery has gained more and more popularity over the last years. It seems to be advantageous to laparoscopic surgery in selected situations, especially in confined regions like a narrow male pelvis in rectal surgery. Whether robotic-assisted, left-sided colectomies can serve as safe training operations for less frequent, low anterior resections for rectal cancer is still under debate. Therefore, the aim of this study was to evaluate intra- and postoperative results of robotic-assisted laparoscopy (RAL) compared to laparoscopic (LSC) surgery in left-sided colectomies. Methods Between June 2015 and December 2019, 683 patients undergoing minimally invasive left-sided colectomies in two Swiss, high-volume colorectal centers were included. Intra- and postoperative outcome parameters were collected and analyzed. Results A total of 179 patients undergoing RAL and 504 patients undergoing LSC were analyzed. Baseline characteristics showed similar results. Intraoperative complications occurred in 0.6% of RAL and 2.0% of LSC patients ( p = 0.193). Differences in postoperative complications graded Dindo ≥ 3 were not statistically significant (RAL 3.9% vs. LSC 6.3%, p = 0.227). Occurrence of anastomotic leakages showed no statistically significant difference [RAL n = 2 (1.1%), LSC n = 8 (1.6%), p = 0.653]. Length of hospital stay was similar in both groups. Conversions to open surgery were significantly higher in the LSC group (6.2% vs.1.7%, p = 0.018), while stoma formation was similar in both groups [RAL n = 1 (0.6%), LSC n = 5 (1.0%), p = 0.594]. Operative time was longer in the RAL group (300 vs. 210.0 min, p < 0.001). Conclusion Robotic-assisted, left-sided colectomies are safe and feasible compared to laparoscopic resections. Intra- and postoperative complications are similar in both groups. Most notably, the rate of anastomotic leakages is similar. Compared to laparoscopic resections, the analyzed robotic-assisted resections have longer operative times but less conversion rates. Further prospective studies are needed to confirm the safety of robotic-assisted, left-sided colectomies as training procedures for low anterior resections.
