Context Neurourological patients often encounter bacteriuria without any symptoms or may experience symptoms suspicious of urinary tract infections (UTIs). However, there is a lack of guidelines that unequivocally state the definition of UTIs in this specific patient group. Objective To present all used definitions of UTIs in neurourological patients. Evidence acquisition This systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. Studies were identified by electronic search of Medline, Embase, Cochrane controlled trials databases, and clinicaltrial.gov without a time limitation (last search September 2020) and by screening of reference lists and reviews. The occurrences of the various UTI definitions were counted and the frequencies calculated. Evidence synthesis After screening 7164 abstracts, we included 32 studies enrolling a total of 8488 patients with a neurourological disorder who took part in an interventional clinical study. UTI definitions were heterogeneous. The concordance to predefined definitions was low. Conclusions Interventional clinical studies rarely report specific definitions for UTIs, and both clinical and laboratory criteria used are heterogeneous. A generally accepted UTI definition for neurourological patients is urgently needed. Patient summary Patients suffering from neurological disorders often experience symptoms in their lower urinary tract that resemble urinary tract infections. Furthermore, they can have positive urine cultures without symptoms (the so-called asymptomatic bacteriuria). However, clinical studies rarely report specific definitions for urinary tract infections, and when it is done, they are heterogeneous. A generally accepted urinary tract infection definition for neurourological patients is urgently needed. Take Home Message Interventional clinical studies on neurourological patients rarely report specific definitions for urinary tract infections (UTIs), and both clinical and laboratory criteria used are heterogeneous. A generally accepted UTI definition for neurourological patients is urgently needed.

Studies consistently suggest that work as a physical therapist is associated with burnout, yet no review of the contributing factors has been conducted.To identify and examine the risk factors associated with physical therapist burnout.PubMed, Embase, CINAHL, and the Cochrane Library were searched from inception to May 2020.Quantitative studies of physical therapists in clinical practice who experience burnout symptoms or syndrome.Risk factors such as characteristics of the participant, environment, structures, and experiences that demonstrate a significant predisposition to burnout were extracted. The modified Downs and Black checklist was used to identify risk of bias.Forty-six studies (8717 participants) were included. The risk of bias assessment determined all were of fair or poor quality. Fifty-three risk factors were identified, with four being classified as unavoidable and forty-nine determined as avoidable. The avoidable risk factors were further categorized as either structural/organizational (32%), psychological/emotional (19%), environmental (19%), or sociodemographic (13%).A risk factor's importance may not correlate with its prevalence, and the low-quality studies limit the ability to make definitive conclusions.A significant amount of literature has identified a wide variety of risk factors. The majority are avoidable, and the effect and degree to which each risk factor contributes to burnout varies. The identified risk factors can help develop targeted prevention and intervention strategies for the benefit of physical therapists, organizations, and policymakers.This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors.PROSPERO CRD42020136356.

Context Controversy still exists regarding the balance of benefits and harms for the different surgical options for neurogenic stress urinary incontinence (N-SUI). Objective To identify which surgical option for N-SUI offers the highest cure rate and best safety without compromising urinary tract function and bladder management. Evidence acquisition A systematic review was performed under the auspices of the European Association of Urology Guidelines Office and the European Association of Urology Neuro-Urology Guidelines Panel according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) statement. Evidence synthesis A total of 32 studies were included. Overall, 852 neurourological patients were surgically treated for N-SUI. The treatment offered most often (13/32 studies) was an artificial urinary sphincter (AUS; 49%, 416/852) and was associated with a need for reintervention in one-third of patients. More than 200 surgical revisions were described. Overall, 146/852 patients (17%) received concomitant bladder augmentation, mainly during placement of an AUS (42%, 62/146) or autologous sling (34% of women and 14% of men). Following pubovaginal sling placement, dryness was achieved in 83% of cases. A significant improvement in N-SUI was observed in 87% (82/94) of women following placement of a synthetic midurethral sling. Efficacy after insertion of an adjustable continence therapy device (ACT 40%, proACT 60%) was reported for 38/128 cases (30%). The cure rate for bulking agents was 35% (9/25) according to 2/32 studies, mainly among men (90%). The risk of bias was highly relevant. Baseline and postoperative cystometry were missing in 13 and 28 studies, respectively. Conclusions The evidence is mainly reported in retrospective studies. More than one intervention is often required to achieve continence because of coexisting neurogenic detrusor overactivity, low compliance, or the onset of complications in the medium and long term. Urodynamic data are needed to better clarify the success of N-SUI treatment with the different techniques. Patient summary Our review shows that insertion of an artificial urinary sphincter for urinary incontinence is effective but is highly associated with a need for repeat surgery. Other surgical options may have lower continence rates or a risk of requiring intermittent catheterization, which patients should be informed about before deciding on surgery for their incontinence.

Describe graft and overall survival outcomes in multiple myeloma (MM) patients who underwent kidney transplant (KT) compared to the general KT population.The Organ Procurement and Transplantation Network/National United Network for Organ Sharing (OPTON/UNOS) database was analyzed from 1988 to 2019 with R 4.00 and the 2013-2017 United States Renal Data System (USRDS) was surveyed for incidence and mortality of MM ESRD.USRDS analysis revealed 961 patients diagnosed with ESRD due to MM on average annually, accounting for 0.8% of the ESRD population. Without KT, 44.4% of MM patients died in the first year of renal replacement initiation. OPTON/UNOS analysis identified 218 MM KT patients, compared to 490,089 patients without MM. There was no difference in graft survival between MM KT and the general population (P-value = .13, HR = 1.19 [0.95, 1.49], 95% CI). Median graft survival in MM KT was 2683 days (7.4 years). KT patients with MM had a higher risk for death (P-value = .0001, HR = 1.83 [1.41, 2.37], 95% CI), and median overall survival was 3076 days (8.4 years). Survival difference was lost when comparing patients ≥50 years (P-value = .42, HR = 1.14 [0.83, 1.56], 95% CI).Patients with MM renal failure who underwent KT had equivalent graft and age-matched overall survival compared to the general KT population. Therefore select patients with MM renal failure have potential for excellent KT outcomes, should be considered for transplantation when feasible, and should not be excluded from KT based on a history of MM.

Population health management (PHM) is an important approach to promote wellness and deliver health care to targeted individuals who meet criteria for preventive measures or treatment. A critical component for any PHM program is a data analytics platform that can target those eligible individuals. Objective The aim of this study was to design and implement a scalable standards-based clinical decision support (CDS) approach to identify patient cohorts for PHM and maximize opportunities for multi-site dissemination. Materials and Methods An architecture was established to support bidirectional data exchanges between heterogeneous electronic health record (EHR) data sources, PHM systems, and CDS components. HL7 Fast Healthcare Interoperability Resources and CDS Hooks were used to facilitate interoperability and dissemination. The approach was validated by deploying the platform at multiple sites to identify patients who meet the criteria for genetic evaluation of familial cancer. Results The Genetic Cancer Risk Detector (GARDE) platform was created and is comprised of four components: (1) an open-source CDS Hooks server for computing patient eligibility for PHM cohorts, (2) an open-source Population Coordinator that processes GARDE requests and communicates results to a PHM system, (3) an EHR Patient Data Repository, and (4) EHR PHM Tools to manage patients and perform outreach functions. Site-specific deployments were performed on onsite virtual machines and cloud-based Amazon Web Services. Discussion GARDE’s component architecture establishes generalizable standards-based methods for computing PHM cohorts. Replicating deployments using one of the established deployment methods requires minimal local customization. Most of the deployment effort was related to obtaining site-specific information technology governance approvals.

Introduction Haemophilia patients with inhibitors often require a bypassing agent (BPA) for bleeding episode management. Eptacog beta (EB) is a new FDA-approved recombinant activated human factor VII BPA for the treatment and control of bleeding in haemophilia A or B patients with inhibitors (≥12 years of age). We describe here the EB safety profile from the three prospective Phase 3 clinical trials performed to date. Aim To assess EB safety, immunogenicity and thrombotic potential in children and adults who received EB for treatment of bleeding and perioperative care. Methods Using a randomized crossover design, 27 subjects in PERSEPT 1 (12-54 years) and 25 subjects in PERSEPT 2 (1-11 years) treated bleeding episodes with 75 or 225 μg/kg EB initially followed by 75 μg/kg dosing at predefined intervals as determined by clinical response. Twelve PERSEPT 3 subjects (2-56 years) received an initial preoperative infusion of 75 μg/kg (minor procedures) or 200 μg/kg EB (major surgeries) with subsequent 75 μg/kg doses administered intraoperatively and post-operatively as indicated. Descriptive statistics were used for data analyses. Results Sixty subjects who received 3388 EB doses in three trials were evaluated. EB was well tolerated, with no allergic, hypersensitivity, anaphylactic or thrombotic events reported and no neutralizing anti-EB antibodies detected. A death occurred during PERSEPT 3 and was determined to be unlikely related to EB treatment by the data monitoring committee. Conclusion Results from all three Phase 3 trials establish an excellent safety profile of EB in haemophilia A or B patients with inhibitors for treatment of bleeding and perioperative use.

Introduction Surgical procedures in persons with haemophilia A or B with inhibitors (PwHABI) require the use of bypassing agents (BPA) and carry a high risk of complications. Historically, only two BPAs have been available; these are reported to have variable responses. Aim To prospectively evaluate the efficacy and safety of a new bypassing agent, human recombinant factor VIIa (eptacog beta) in elective surgical procedures in PwHABI in a phase 3 clinical trial, PERSEPT 3. Methods Subjects were administered 200 µg/kg (major procedures) or 75 µg/kg eptacog beta (minor procedures) immediately prior to the initial surgical incision; subsequent 75 µg/kg doses were administered to achieve postoperative haemostasis and wound healing. Efficacy was assessed on a 4-point haemostatic scale during the intra- and postoperative periods. Anti-drug antibodies, thrombotic events and changes in clinical/laboratory parameters were monitored throughout the perioperative period. Results Twelve subjects underwent six major and six minor procedures. The primary efficacy endpoint success proportion was 100% (95% CI: 47.8%-100%) for minor procedures and 66.7% (95% CI: 22.3%-95.7%) for major procedures; 81.8% (95% CI: 48.2%-97.7%) of the procedures were considered successful using eptacog beta. There was one death due to bleeding from a nonsurgical site; this was assessed as unlikely related to eptacog beta. No thrombotic events or anti-eptacog beta antibodies were reported. Conclusion Two eptacog beta dosing regimens in PwHABI undergoing major and minor surgical procedures were well-tolerated, and the majority of procedures were successful based on surgeon/investigator assessments. Eptacog beta offers clinicians a new potential therapeutic option for procedures in PwHABI.

Immunodominance is a complex and highly debated topic of T cell biology. The current SARS-CoV-2 pandemic has provided the opportunity to profile adaptive immune responses and determine molecular factors contributing to emerging responses towards immunodominant viral epitopes. Here, we discuss parameters that alter the dynamics of CD8 viral epitope processing, generation and T-cell responses, and how immunodominance counteracts viral immune escape mechanisms that develop in the context of emerging SARS-CoV-2 variants.

We aimed to provide a real-world description of neurogenic lower urinary tract dysfunction within the first year after spinal cord injury with a focus on unfavorable urodynamic parameters that are associated with urological morbidity.Urodynamic investigations from 97 patients with traumatic or ischemic acute spinal cord injury and managed according to the European Association of Urology Guidelines on Neuro-Urology were analyzed at a single university spinal cord injury center at 1 month, 3 months, 6 months, and 12 months after injury. Unfavorable urodynamic parameters were defined as detrusor overactivity in combination with detrusor sphincter dyssynergia, maximum storage detrusor pressure of 40 cm HOne or more unfavorable urodynamic parameter was observed in 87 out of 97 patients (90%) within the first year after spinal cord injury. Eighty-eight percent of the patients showed detrusor overactivity with detrusor sphincter dyssynergia, 39% a maximum storage detrusor pressure of 40 cm HUsing a standardized urodynamic follow-up schedule, we found unfavorable urodynamic parameters in a majority of the population within the first year after spinal cord injury. As early treatment based on urodynamic findings might reduce the risk of deterioration of upper and lower urinary tract function, thereby improving long-term outcomes, there is need for further research regarding recommendations for a urodynamic follow-up schedule during the first year after spinal cord injury.

The RNA-binding protein IGF2BP2/IMP2/VICKZ2/p62 is overexpressed in several tumor entities, promotes tumorigenesis and tumor progression, and has been suggested to worsen the disease outcome. The aim of this study is to (I) validate IMP2 as a potential target for colorectal cancer, (II) set up a screening assay for small-molecule inhibitors of IMP2, and (III) test the biological activity of the obtained hit compounds. Analyses of colorectal and liver cancer gene expression data showed reduced survival in patients with a high IMP2 expression and in patients with a higher IMP2 expression in advanced tumors.

Adult expression of IMP2 is often associated with several types of disease and cancer. The RNA binding protein IMP2 binds and stabilizes the IGF2 mRNA as well as hundreds of other transcripts during development. To gain insight into the molecular action of IMP2 and its contribution to disease in context of adult cellular metabolism, we analyze transgenic overexpression of IMP2 in mouse livers, which has been shown to induce a steatosis-like phenotype and enhanced risk to develop hepatocellular carcinoma (HCC). Our data show up-regulation of several HCC marker genes and miRNAs (miR438-3p and miR151-5p). To characterize the impact of miRNAs to their targets, integrative analysis of transcriptome-and miRNAome-dynamics in combination with IMP2 target prediction was carried out. Our analyses show that targets of expressed miRNAs become accumulated in the case that these transcripts have positive IMP2 binding prediction. Therefore, our data indicates that overexpression of IMP2 alters the regulatory capacity of many miRNAs and we conclude that IMP2 competes with miRNAs for binding sites on thousands of transcripts. As a result, our data implicates that overexpression of IMP2 has distinct effects to the regulatory capacity of miRNAs with yet unknown consequences for translational efficiency.

We describe a proteomics analysis to determine the molecular differences between normothermically perfused (normothermic machine perfusion, NMP) human kidneys with urine recirculation (URC) and urine replacement (UR). Proteins were extracted from 16 kidney biopsies with URC (n = 8 donors after brain death [DBD], n = 8 donors after circulatory death [DCD]) and three with UR (n = 2 DBD, n = 1 DCD), followed by quantitative analysis by mass spectrometry. Damage‐associated molecular patterns (DAMPs) were decreased in kidney tissue after 6 hours NMP with URC, suggesting reduced inflammation. Vasoconstriction was also attenuated in kidneys with URC as angiotensinogen levels were reduced. Strikingly, kidneys became metabolically active during NMP, which could be enhanced and prolonged by URC. For instance, mitochondrial succinate dehydrogenase enzyme levels as well as carbonic anhydrase were enhanced with URC, contributing to pH stabilization. Levels of cytosolic and the mitochondrial phosphoenolpyruvate carboxykinase were elevated after 24 hours of NMP, more prevalent in DCD than DBD tissue. Key enzymes involved in glucose metabolism were also increased after 12 and 24 hours of NMP with URC, including mitochondrial malate dehydrogenase and glutamic‐oxaloacetic transaminase, predominantly in DCD tissue. We conclude that NMP with URC permits prolonged preservation and revitalizes metabolism to possibly better cope with ischemia reperfusion injury in discarded kidneys., The authors perform a proteomics analysis to identify molecular differences between normothermically machine perfused and discarded human kidneys with urine recirculation and urine replacement using lactated Ringers.

Summary Background Urinary tract infections (UTIs) are among the most prevalent microbial diseases and their financial burden on society is substantial. In the context of increasing antibiotic resistance, finding alternative treatments for UTIs is a top priority. We aimed to determine whether intravesical bacteriophage therapy with a commercial bacteriophage cocktail is effective in treating UTI. Methods We did a randomised, placebo-controlled, clinical trial, at the Alexander Tsulukidze National Centre of Urology, Tbilisi, Georgia. Men older than 18 years of age, who were scheduled for transurethral resection of the prostate (TURP), with complicated UTI or recurrent uncomplicated UTI but no signs of systemic infection, were allocated by block randomisation in a 1:1:1 ratio to receive intravesical Pyo bacteriophage (Pyophage; 20 mL) or intravesical placebo solution (20 mL) in a double-blind manner twice daily for 7 days, or systemically applied antibiotics (according to sensitivities) as an open-label standard-of-care comparator. Urine culture was taken via urinary catheter at the end of treatment (ie, day 7) or at withdrawal from the trial. The primary outcome was microbiological treatment response after 7 days of treatment, measured by urine culture; secondary outcomes included clinical and safety parameters during the treatment period. Analyses were done in a modified intention-to-treat population of patients having received at least one dose of the allocated treatment regimen. This trial is registered with ClinicalTrials.gov , NCT03140085 . Findings Between June 2, 2017, and Dec 14, 2018, 474 patients were screened for eligibility and 113 (24%) patients were randomly assigned to treatment (37 to Pyophage, 38 to placebo, and 38 to antibiotic treatment). 97 patients (28 Pyophage, 32 placebo, 37 antibiotics) received at least one dose of their allocated treatment and were included in the primary analysis. Treatment success rates did not differ between groups. Normalisation of urine culture was achieved in five (18%) of 28 patients in the Pyophage group compared with nine (28%) of 32 patients in the placebo group (odds ratio [OR] 1·60 [95% CI 0·45–5·71]; p=0·47) and 13 (35%) of 37 patients in the antibiotic group (2·66 [0·79–8·82]; p=0·11). Adverse events occurred in six (21%) of 28 patients in the Pyophage group compared with 13 (41%) of 32 patients in the placebo group (OR 0·36 [95% CI 0·11–1·17]; p=0·089) and 11 (30%) of 37 patients in the antibiotic group (0·66 [0·21–2·07]; p=0·47). Interpretation Intravesical bacteriophage therapy was non-inferior to standard-of-care antibiotic treatment, but was not superior to placebo bladder irrigation, in terms of efficacy or safety in treating UTIs in patients undergoing TURP. Moreover, the bacteriophage safety profile seems to be favourable. Although bacteriophages are not yet a recognised or approved treatment option for UTIs, this trial provides new insight to optimise the design of further large-scale clinical studies to define the role of bacteriophages in UTI treatment.

Sex differences in jealousy responses to sexual and emotional infidelity are robust in samples of heterosexual adults, especially in more gender egalitarian nations. However, investigations of when and how these differences develop have been scant. We applied two forced choice infidelity scenarios in a large community sample of high school students (age 16–19, N = 1266). In line with previous findings on adults using the forced choice paradigm, adolescent males found the sexual aspect of imagined infidelity more distressing than adolescent females did. Nevertheless, there was no effect of age on the jealousy responses, and age did not moderate the sex difference. There were neither any effects of three covariates (having had first sexual intercourse, being in a committed romantic relationship, and sociosexuality), neither as markers of pubertal maturation nor as psychosocial environmental stimuli. Future research needs to investigate even younger samples in order to specify at what age the sex difference in jealousy responses emerges.

Background and Purpose: Fewer women than men tend to be enrolled in clinical trials of intracerebral hemorrhage. It is unclear whether this reflects lower prevalence of intracerebral hemorrhage in women, selection bias, or poor recruitment efforts. We undertook this study to examine differences between men and women in the reasons for exclusion from the iDEF trial (Intracerebral Hemorrhage Deferoxamine). Methods: The screen failure log included 29 different reasons for exclusion. Chi-square statistics were used to evaluate the differences in reasons for exclusion between men and women. Results: A total of 38.2% of participants in iDEF were women. Three thousand nine hundred eighty-two women (45.7%) and 4736 men (54.3%) were screen failures ( P P =0.1). Patients or families declined participation in 1.26% of women versus 1.31% of men ( P =0.9). More women than men failed screening because of age>80 (22.40% versus 12.61%; adjusted P =0.0007) and preexisting do-not-resuscitate/do-not-intubate (3.69% versus 2.83%; adjusted P =0.067). Conclusions: Lower rates of women enrollment in the iDEF trial may be attributed to older age. Inability to obtain consent or declining participation was similar between women and men, arguing against selection bias. Our findings should be confirmed in other intracerebral hemorrhage trials to determine best strategies to improve women’s representation in future trials.

Middle- and inner-ear surgery is a vital treatment option in hearing loss, infections, and tumors of the lateral skull base. Segmentation of otologic structures from computed tomography (CT) has many potential applications for improving surgical planning but can be an arduous and time-consuming task. We propose an end-to-end solution for the automated segmentation of temporal bone CT using convolutional neural networks (CNN). Using 150 manually segmented CT scans, a comparison of 3 CNN models (AH-Net, U-Net, ResNet) was conducted to compare Dice coefficient, Hausdorff distance, and speed of segmentation of the inner ear, ossicles, facial nerve and sigmoid sinus. Using AH-Net, the Dice coefficient was 0.91 for the inner ear; 0.85 for the ossicles; 0.75 for the facial nerve; and 0.86 for the sigmoid sinus. The average Hausdorff distance was 0.25, 0.21, 0.24 and 0.45 mm, respectively. Blinded experts assessed the accuracy of both techniques, and there was no statistical difference between the ratings for the two methods (p = 0.93). Objective and subjective assessment confirm good correlation between automated segmentation of otologic structures and manual segmentation performed by a specialist. This end-to-end automated segmentation pipeline can help to advance the systematic application of augmented reality, simulation, and automation in otologic procedures.

Approximately 70% of breast cancers express estrogen receptor α (ERα) and depend on this key transcriptional regulator for proliferation and differentiation. While patients with this disease can be treated with targeted antiendocrine agents, drug resistance remains a significant issue, with almost half of patients ultimately relapsing. Elucidating the mechanisms that control ERα function may further our understanding of breast carcinogenesis and reveal new therapeutic opportunities. Here, we investigated the role of deubiquitinases (DUB) in regulating ERα in breast cancer. An RNAi loss-of-function screen in breast cancer cells targeting all DUBs identified USP11 as a regulator of ERα transcriptional activity, which was further validated by assessment of direct transcriptional targets of ERα. USP11 expression was induced by estradiol, an effect that was blocked by tamoxifen and not observed in ERα-negative cells. Mass spectrometry revealed a significant change to the proteome and ubiquitinome in USP11-knockdown (KD) cells in the presence of estradiol. RNA sequencing in LCC1 USP11-KD cells revealed significant suppression of cell-cycle–associated and ERα target genes, phenotypes that were not observed in LCC9 USP11-KD, antiendocrine-resistant cells. In a breast cancer patient cohort coupled with in silico analysis of publicly available cohorts, high expression of USP11 was significantly associated with poor survival in ERα-positive (ERα+) patients. Overall, this study highlights a novel role for USP11 in the regulation of ERα activity, where USP11 may represent a prognostic marker in ERα+ breast cancer. Significance: A newly identified role for USP11 in ERα transcriptional activity represents a novel mechanism of ERα regulation and a pathway to be exploited for the management of ER-positive breast cancer.

Study Design Simulations using data from a prospective cohort study. Objectives To illustrate how prospective cohort data can be employed in randomized controlled trial (RCT) planning to assess feasibility and operational challenges, using TASCI (Transcutaneous tibial nerve stimulation in patients with Acute Spinal Cord Injury to prevent neurogenic detrusor overactivity: a nationwide randomized, sham-controlled, double-blind clinical trial) as a case study. Setting Spinal cord injury rehabilitation centers in Switzerland. Methods TASCI is nested in the multicenter Swiss Spinal Cord Injury Cohort Study (SwiSCI), which prospectively includes patients with acute spinal cord injury. In simulations, data from 640 patients, collected by SwiSCI, were used to investigate different scenarios of patient eligibility and study consent, as well as the performance of the randomization list. Descriptive analysis was used to describe the population of interest and the simulation results; multivariable logistic regression analysis was performed to identify predictors of discharge within the TASCI intervention time period. Results The recruitment target of 114 patients is obtainable within the originally envisioned three-year time period under the most favorable recruitment scenario examined. The distribution of the primary prognostic factor produced imbalance in the randomization lists and informed further discussion of the cut-off values used in stratification. Influxes of patients resulted in overlapping intervention periods for multiple participants, which guided resource allocation. Early discharge was related to the primary prognostic factor and study center, but is only anticipated in about 8% of participants. Conclusions Prospective cohort data are a very valuable resource for planning RCTs.

Introduction Real‐world data are lacking regarding the relationship between prospectively collected patient‐reported outcomes (PROs), clinical outcomes and treatment in people with haemophilia (PWH). The Expanding Communications on Hemophilia A Outcomes (ECHO) registry was designed to address this data gap, but a range of difficulties led to early study closure. Aim To describe the challenges faced and lessons learned from implementing a multinational haemophilia registry. Methods The Expanding Communications on Hemophilia A Outcomes was planned as a five‐year observational cohort study to collect data from 2000 patients in nine countries. Based on direct observations, feedback from patients enrolled in ECHO, challenges of the study design and input from study‐sponsor representatives, the ECHO Steering Committee systematically identified the challenges faced and developed recommendations for overcoming or avoiding them in future studies. Results The study closed after two years because few countries were activated and patient recruitment was low. This was related to multiple challenges including delayed implementation, stringent pharmacovigilance requirements, objections of investigators and patients to the burden of multiple PROs, data collection issues, lack of resources at study sites, little engagement of patients and competing clinical trials, which further limited recruitment. At study closure, 269 patients had been enrolled in four of nine participating countries. Conclusions Researchers planning studies similar to ECHO may want to consider the barriers identified in this global registry of PWH and suggestions to mitigate these limitations, such as greater patient involvement in design and analysis, clearer assessment and understanding of local infrastructure and potential changes to the administration of the study.

Background Urodynamic investigations have a pivotal role in the diagnosis of lower urinary tract symptoms. Despite expert statements and guidelines supporting their usefulness for clinical decision making in various clinical domains, the academic debate remains controversial. Objective To provide a metaepidemiological inventory of studies assessing the diagnostic properties of urodynamic investigations. Design, setting, and participants Systematic searches without language restrictions were performed in (Pre-)Medline, EMBASE, and the Cochrane Library from inception until August 31, 2018. Checking of reference lists of included studies and reviews complemented searches. Records were compiled and screened for possible inclusion by reading title and abstracts by two teams of two research fellows. Inclusion criteria were as follows: prospective data collection and urodynamic investigations performed either as a diagnostic test or using a therapy monitoring instrument. No a priori selection on clinical domain was done. Double reading was performed on records marked “included.” Extraction into a developed and piloted matrix was performed in duplicate and checked by a third research fellow. Outcome measurements and statistical analysis Of each included article, study specifics, objective, study design, type of data collection, clinical domain, type and description of test used, and type of outcome were extracted and attributed to a framework. Results and limitations Electronic searches retrieved 20 841 records. After screening, 299 abstracts were considered relevant. The main reasons for exclusion were as follows: animal studies, no primary data, editorial/opinion based on published data or reviews, primary objective of the study being not the assessment of urodynamic investigations, and post hoc (opportunistic) correlation studies. Conclusions To our knowledge, this is the first comprehensive collection of studies assessing the clinical usefulness of urodynamic investigations. The collection is the starting point for a series of systematic reviews assessing the diagnostic properties of urodynamic investigations. Patient summary The usefulness of urodynamic investigations for clinical decision making is under debate. We established an inventory of diagnostic studies on urodynamics to assess the value of urodynamics in various clinical applications.

Acquired hemophilia A (AHA), a rare bleeding disorder caused by neutralizing autoantibodies against coagulation factor VIII (FVIII), occurs in both men and women without a previous history of bleeding. Patients typically present with an isolated prolonged activated partial thromboplastin time due to FVIII deficiency. Neutralizing antibodies (inhibitors) are detected using the Nijmegen-modified Bethesda assay. Approximately 10% of patients do not present with bleeding and, therefore, a prolonged activated partial thromboplastin time should never be ignored prior to invasive procedures. Control of acute bleeding and prevention of injuries that may provoke bleeding are top priorities in patients with AHA. We recommend treatment with bypassing agents, including recombinant activated factor VII, activated prothrombin complex concentrate, or recombinant porcine FVIII in bleeding patients. Autoantibody eradication can be achieved with immunosuppressive therapy, including corticosteroids, cyclophosphamide and rituximab, or combinations thereof. The median time to remission is 5 weeks, with considerable interindividual variation. FVIII activity at presentation, inhibitor titer and autoantibody isotype are prognostic markers for remission and survival. Comparative clinical studies to support treatment recommendations for AHA do not exist; therefore, we provide practical consensus guidance based on recent registry findings and the authors’ clinical experience in treating patients with AHA.

Bacterial urinary tract infections (UTIs) are very frequent, especially in patients with neurogenic lower urinary tract dysfunction (NLUTD). The steady increase in antibiotic resistance among causative bacteria prompts the search for highly effective therapeutic alternatives with little or no side effects. Bacteriophages - obligate intracellular viruses that solely infect and kill bacteria - are promising tools for treating bacterial infections and have been used for this purpose for almost a century. Recent clinical studies using bacteriophage therapy for UTIs showed encouraging results. In particular, patients with recurrent UTIs, such as individuals with NLUTD who rely on assisted bladder emptying, might benefit from this treatment method. However, bacteriophages are not yet a panacea. More high-quality basic and clinical research on bacteriophage therapy is needed to answer questions on the use of this therapeutic option and its potential to provide a solution to the global threat of multidrug-resistant bacteria. PATIENT SUMMARY: Urinary tract infections are very common, especially in patients with neurogenic lower urinary tract dysfunction. In this review we discuss the potential of bacteriophage therapy as an alternative to antibiotics for treating patients with bladder infections.

Background: Routine use of urodynamics (UDS) for the assessment of female stress urinary incontinence (SUI) appears to be in decline across Europe. The reasons for this trend appear multifactorial, but the implications are of significant concern. Objectives: To achieve an expert consensus viewpoint on the value of UDS in female SUI and current barriers to its use. Methodology: A multidisciplinary group of UDS experts from six European countries was convened, and a modified version of the Delphi method was utilised to reach a consensus viewpoint structured around five key questions. Results: Consensus was achieved on all five questions. The group was unanimous that the decline in routine use of UDS is unjustified and misguided, driven by restrictions in funding and accelerated by the publication-and subsequent influence-of two trials that had major limitations. Limitations: The authors comprised a selected group of UDS experts and the analysis is not a formal systematic review. Conclusions: Extensive experience and observational studies have demonstrated the value of UDS for the assessment of female SUI and the dangers of empiric management. This evidence base should not be eclipsed by the findings of two randomised controlled trials that had numerous shortcomings. Patient summary: A group of experts were worried that, even though the cause of incontinence varies, doctors seem to be skipping a diagnostic test called urodynamics (UDS) in some patients and just providing treatment-even surgery-without knowing exactly what is wrong. These experts analysed the situation in detail and reached agreement that UDS testing should not be skipped. (C) 2019 European Association of Urology. Published by Elsevier B.V.

Zinc-finger nuclease (ZFN)-based in vivo genome editing is a novel treatment that can potentially provide lifelong protein replacement with single intravenous administration. Three first-in-human open-label ascending single-dose phase 1/2 studies were performed in parallel (starting November 2017) primarily to assess safety and tolerability of ZFN in vivo editing therapy in mucopolysaccharidosis I (MPS I) (n = 3), MPS II (n = 9), and hemophilia B (n = 1). Treatment was well tolerated with no serious treatment-related adverse events. At the 1e13 vg/kg dose, evidence of genome editing was detected through albumin-transgene fusion transcripts in liver for MPS II (n = 2) and MPS I (n = 1) subjects. The MPS I subject also had a transient increase in leukocyte iduronidase activity to the lower normal range. At the 5e13 vg/kg dose, one MPS II subject had a transient increase in plasma iduronate-2-sulfatase approaching normal levels and one MPS I subject approached mid-normal levels of leukocyte iduronidase activity with no evidence of genome editing. The hemophilia B subject was not able to decrease use of factor IX concentrate; genome editing could not be assessed. Overall, ZFN in vivo editing therapy had a favorable safety profile with evidence of targeted genome editing in liver, but no long-term enzyme expression in blood.

Flirting involves various signals communicated between individuals. To attract potential mates, men and women exhibit flirtatious behavior to get the attention of, and potentially elicit sexual or romantic interest from, a desired partner. In this first large, preregistered study of judgement of the effectiveness of flirtation tactics based on Sexual Strategies Theory, we considered the effects of flirter’s (actor) sex and mating contexts in addition to rater's (participant) sex across two cultures, Norway and the U.S. Culturally relevant covariates such as sociosexuality, extraversion, mate value, age, and religiosity were examined. Participants from Norway (N = 415, 56% women) and the US (N = 577, 69% women) responded to one of four different randomized questionnaires representing a factorial design considering either short-term versus long-term mating context and either female or male sex of actor. We found that sexual availability cues were judged more effective when employed by women in short-term mating contexts. Friendly contact, such as hugs or kissing on the cheek, was not. Cues to generosity and commitment were judged more effective when employed by men in long-term mating contexts. Humor was rated as more effective when used by men and in long-term contexts, and least effective when used by women in short term contexts. However, laughing or giggling at someone's jokes was an effective flirtation tactic for both sexes. Overall, predictions for culturally relevant covariates were not supported, but cultural differences were found in bodily displays, initial contact, and generosity. These findings dovetail neatly with findings from the self-promotion literature, and further support that flirtation is a universal mate signaling strategy.

Medulloblastoma is the most common malignant brain tumour in children. Genomic studies have identified distinct disease subgroups: wnt/wingless (WNT), sonic hedgehog (SHH), and non-WNT/non-SHH, comprising group 3 and group 4. Alterations in WNT and SHH signalling form the pathogenetic basis for their subgroups, whereas those for non-WNT/non-SHH tumours remain largely elusive. Recent analyses have revealed recurrent in-frame insertions in the E3 ubiquitin ligase adaptor Kelch Repeat and BTB Domain Containing 4 (KBTBD4) in cases of group 3/4 medulloblastoma. Critically, group 3/4 tumours with KBTBD4 mutations typically lack other gene-specific alterations, such as MYC amplification, indicating KBTBD4 insertion mutations as the primary genetic driver. Delineating the role of KBTBD4 mutations thus offers significant opportunities to understand tumour pathogenesis and to exploit the underpinning mechanisms therapeutically. Here, we show a novel mechanism in cancer pathogenesis whereby indel mutations in KBTBD4 drive its recognition of neo-substrates for degradation. We observe that KBTBD4 mutants promote the recruitment and ubiquitylation of the REST Corepressor (CoREST), which forms a complex to modulate chromatin accessibility and transcriptional programmes. The degradation of CoREST promoted by KBTBD4 mutation diverts epigenetic programmes inducing significant alterations in transcription to promote increased stemness of cancer cells. Transcriptional analysis of >200 human group 3 and 4 medulloblastomas by RNA-seq, highlights the presence of CoREST and stem-like signatures in tumours with KBTBD4 mutations, which extend to a further sub-set of non-mutant tumours, suggesting CoREST alterations as a novel pathogenetic mechanism of wide relevance in groups 3 and 4. Our findings uncover KBTBD4 mutation as a novel driver of epigenetic reprogramming in non-WNT/non-SHH medulloblastoma, establish a novel mode of tumorigenesis through gain-of-function mutations in ubiquitin ligases (neo-substrate recruitment) and identify both mutant KBTBD4 and CoREST complexes as new druggable targets for improved tumour-specific therapies.

The nature and the intensity of innate immune response to virus infection determine the course of pathogenesis in the host. Among the many pathogen-associated molecular pattern recognition receptors, STING, an endoplasmic reticulum (ER)-associated protein, plays a pivotal role in triggering responses to microbial or cellular cytoplasmic DNA. Herpes simplex virus 1 (HSV-1), a common human pathogen, activates STING signaling, and the resultant induction of type I interferon causes inhibition of virus replication. In this context, we have observed that phosphorylation of Tyr245 of STING by epidermal growth factor receptor kinase is necessary for interferon induction. Here, we report that phosphorylation of Tyr240 by the tyrosine kinase Syk is essential for all signaling activities of STING. Our analysis showed that upon ligand-binding, STING dimerizes and interacts with membrane-bound EGFR, which autophosphorylates and provides the platform for the recruitment of cytoplasmic Syk to the signaling complex and its activation. Activated Syk phosphorylates Tyr240 of STING, followed by phosphorylation of Tyr245 by epidermal growth factor receptor (EGFR). Pharmacological or genetic ablation of Syk activity resulted in an arrest of STING in the ER compartment and a complete block of gene induction. Consequently, in the absence of Syk, HSV-1 could not induce interferon, and it replicated more robustly. IMPORTANCE The innate immune response to virus infection leads to interferon production and inhibition of viral replication. STING, an ER-bound protein, mediates such a response to cytoplasmic cellular or microbial DNA. HSV-1, a DNA virus, activates STING, and it replicates more efficiently in the absence of STING signaling. We demonstrate that phosphorylation of Tyr240 of STING by the protein tyrosine kinase Syk is essential for STING-mediated gene induction. To signal, ligand-activated STING recruits two kinases, Syk and EGFR, which phosphorylate Tyr240 and Tyr245, respectively. The dependence of STING signaling on Syk has broad significance, because STING plays a major role in many microbial, mitochondrial, and autoimmune diseases as well as in cancer development and therapy.

Interferon regulating factor 5 (IRF5) is a multifunctional regulator of immune responses, and has a key pathogenic function in gut inflammation, but how IRF5 is modulated is still unclear. Having performed a kinase inhibitor library screening in macrophages, here we identify protein-tyrosine kinase 2-beta (PTK2B/PYK2) as a putative IRF5 kinase. PYK2-deficient macrophages display impaired endogenous IRF5 activation, leading to reduction of inflammatory gene expression. Meanwhile, a PYK2 inhibitor, defactinib, has a similar effect on IRF5 activation in vitro, and induces a transcriptomic signature in macrophages similar to that caused by IRF5 deficiency. Finally, defactinib reduces pro-inflammatory cytokines in human colon biopsies from patients with ulcerative colitis, as well as in a mouse colitis model. Our results thus implicate a function of PYK2 in regulating the inflammatory response in the gut via the IRF5 innate sensing pathway, thereby opening opportunities for related therapeutic interventions for inflammatory bowel diseases and other inflammatory conditions., The transcription factor, IRF5, has been implicated in the regulation of inflammation, but how IRF5 protein is activated is still unclear. Here the authors use inhibitor library screening, biochemical analyses and in vivo/ex vivo data to show that a protein tyrosine kinase, Pyk2, may be key for the activation of IRF5 in macrophages and inflammatory responses in the gut.

In brain death, cerebral injury contributes to systemic biological dysregulation, causing significant cellular stress in donor kidneys adversely impacting the quality of grafts. Here, we hypothesized that donation after brain death (DBD) kidneys undergo proteolytic processes that may deem grafts susceptible to posttransplant dysfunction. Using mass spectrometry and immunoblotting, we mapped degradation profiles of cytoskeletal proteins in deceased and living donor kidney biopsies. We found that key cytoskeletal proteins in DBD kidneys were proteolytically cleaved, generating peptide fragments, predominantly in grafts with suboptimal posttransplant function. Interestingly, α-actinin-4 and talin-1 proteolytic fragments were detected in brain death but not in circulatory death or living donor kidneys with similar donor characteristics. As talin-1 is a specific proteolytic target of calpain-1, we investigated a potential trigger of calpain activation and talin-1 degradation using human ex vivo precision-cut kidney slices and in vitro podocytes. Notably, we showed that activation of calpain-1 by transforming growth factor-β generated proteolytic fragments of talin-1 that matched the degradation fragments detected in DBD preimplantation kidneys, also causing dysregulation of the actin cytoskeleton in human podocytes; events that were reversed by calpain-1 inhibition. Our data provide initial evidence that brain death donor kidneys are more susceptible to cytoskeletal protein degradation. Correlation to posttransplant outcomes may be established by future studies.

Lung squamous cell carcinoma (LSCC) is a considerable global health burden, with an incidence of over 600,000 cases per year. Treatment options are limited, and patient’s 5-year survival rate is less than 5%. The ubiquitin-specific protease 28 (USP28) has been implicated in tumourigenesis through its stabilization of the oncoproteins c-MYC, c-JUN, and Δp63. Here, we show that genetic inactivation of Usp28-induced regression of established murine LSCC lung tumours. We developed a small molecule that inhibits USP28 activity in the low nanomole range. While displaying cross-reactivity against the closest homologue USP25, this inhibitor showed a high degree of selectivity over other deubiquitinases. USP28 inhibitor treatment resulted in a dramatic decrease in c-MYC, c-JUN, and Δp63 proteins levels and consequently induced substantial regression of autochthonous murine LSCC tumours and human LSCC xenografts, thereby phenocopying the effect observed by genetic deletion. Thus, USP28 may represent a promising therapeutic target for the treatment of squamous cell lung carcinoma.

Study designCross-sectional study.ObjectivesTo evaluate if specific definitions of detrusor sphincter dyssynergia (DSD) might distinguish between individuals with spinal cord injury (SCI) and those with no underlying neurological disorder (NO ND).SettingSingle tertiary university SCI center.MethodsA series of 153 individuals, 81 with traumatic SCI and 72 with NO ND, were prospectively evaluated and included in this study. All individuals underwent a clinical neuro-urological examination, a neurophysiological work-up and a video-urodynamic investigation and were diagnosed with DSD as defined by the International Continence Society (ICS). We determined the DSD grades/types according to the classifications by Yalla (grade 1–3), Blaivas (type 1–3) and Weld (type 1–2). Distribution of the DSD grades/types were compared between SCI and NO ND individuals. Associations between the various DSD grades/types and clinical parameters, such as risk factors for upper urinary tract damage (all individuals) or lower extremity motor scores, SCI injury levels and severity scores (only SCI group), were assessed.ResultsThe distribution of all DSD types were similar between groups (p > 0.05). None of the DSD classifications allowed risk assessment for upper urinary tract damage. A significant association between DSD type and other clinical parameters could not be found (p > 0.05).ConclusionsNone of the investigated DSD definitions can distinguish between patients with SCI and with NO ND. The more complex DSD classifications by Yalla, Blaivas or Weld cannot compete with the ICS binary yes-no definition which is pragmatic and straightforward for managing patients in daily clinical practice.SponsorshipNone.

Bacterial infections are the leading cause of death in people with a spinal cord injury (SCI). Bacteriophages (phages) are viruses that solely infect and kill bacteria. The idea of using phages to treat bacterial infections, i.e., phage therapy, is very promising and potentially allows a more specific and personalized treatment of bacterial infections than antibiotics. While multi-drug resistant infections affect individuals from the general population, alternative therapeutic options are especially warranted in high-risk populations, such as individuals with SCI. However, more clinical data must be collected before phage therapy can be implemented in clinical practice, with numerous possible, subsequent applications.

Cases of de novo immune thrombocytopenia (ITP), including a fatality, following SARS-CoV-2 vaccination in previously healthy recipients led to studying its impact in preexisting ITP. In this study, 4 data sources were analyzed: the Vaccine Adverse Events Reporting System (VAERS) for cases of de novo ITP; a 10-center retrospective study of adults with preexisting ITP receiving SARS-CoV-2 vaccination; and surveys distributed by the Platelet Disorder Support Association (PDSA) and the United Kingdom (UK) ITP Support Association. Seventy-seven de novo ITP cases were identified in VAERS, presenting with median platelet count of 3 [1-9] ×109/L approximately 1 week postvaccination. Of 28 patients with available data, 26 responded to treatment with corticosteroids and/or intravenous immunoglobulin (IVIG), and/or platelet transfusions. Among 117 patients with preexisting ITP who received a SARS-CoV-2 vaccine, 19 experienced an ITP exacerbation (any of: ≥50% decline in platelet count, nadir platelet count 20% decrease from baseline, and/or use of rescue therapy) following the first dose and 14 of 70 after a second dose. Splenectomized persons and those who received 5 or more prior lines of therapy were at highest risk of ITP exacerbation. Fifteen patients received and responded to rescue treatment. In surveys of both 57 PDSA and 43 UK patients with ITP, prior splenectomy was associated with worsened thrombocytopenia. ITP may worsen in preexisting ITP or be identified de novo post–SARS-CoV2 vaccination; both situations responded well to treatment. Proactive monitoring of patients with known ITP, especially those postsplenectomy and with more refractory disease, is indicated.

Assessment of donor kidney quality is based on clinical scores or requires biopsies for histological assessment. Noninvasive strategies to identify and predict graft outcome at an early stage are, therefore, needed. We evaluated the perfusate of donation after brain death (DBD) kidneys during nonoxygenated hypothermic machine perfusion (HMP). In particular, we compared perfusate protein profiles of good outcome (GO) and suboptimal outcome (SO) 1-year post-transplantation. Samples taken 15 min after the start HMP (T1) and before the termination of HMP (T2) were analysed using quantitative liquid chromatography-tandem mass spectrometry (LC-MS/MS). Hierarchical clustering of the 100 most abundant proteins showed discrimination between grafts with a GO and SO at T1. Elevated levels of proteins involved in classical complement cascades at both T1 and T2 and a reduced abundance of lipid metabolism at T1 and of cytoskeletal proteins at T2 in GO versus SO was observed. ATP-citrate synthase and fatty acid-binding protein 5 (T1) and immunoglobulin heavy variable 2-26 and desmoplakin (T2) showed 91% and 86% predictive values, respectively, for transplant outcome. Taken together, DBD kidney HMP perfusate profiles can distinguish between outcome 1-year post-transplantation. Furthermore, it provides insights into mechanisms that could play a role in post-transplant outcomes.

T cells rely for their development and function on the correct folding and turnover of proteins generated in response to a broad range of molecular cues. In the absence of the eukaryotic type II chaperonin complex, CCT, T cell activation induced changes in the proteome are compromised including the formation of nuclear actin filaments and the formation of a normal cell stress response. Consequently, thymocyte maturation and selection, and T cell homeostatic maintenance and receptor-mediated activation are severely impaired. In the absence of CCT-controlled protein folding, Th2 polarization diverges from normal differentiation with paradoxical continued IFN-γ expression. As a result, CCT-deficient T cells fail to generate an efficient immune protection against helminths as they are unable to sustain a coordinated recruitment of the innate and adaptive immune systems. These findings thus demonstrate that normal T cell biology is critically dependent on CCT-controlled proteostasis and that its absence is incompatible with protective immunity., Communications Biology, 4 (1), ISSN:2399-3642

Prostatic artery embolization (PAE) has been introduced into clinical practice for the treatment of lower urinary tract symptoms secondary to benign prostatic hyperplasia (BPH-LUTS) despite a lack of high-level evidence.To perform a systematic review and meta-analysis of clinical trials comparing efficacy and safety of PAE versus established surgical therapies.Medline, Embase, and York CRD were searched up to June 23, 2018. Only comparative studies were included. The risk of bias was assessed by the Cochrane Collaboration tool. Meta-analyses were performed using RevMan 5.3.Five studies including 708 patients met the selection criteria. Risk of bias was rated high for most of the studies. Mean reduction in the International Prostate Symptom Score was lower after PAE compared with standard surgical therapies (mean difference 3.80 points [95% confidence interval: 2.77-4.83]; p0.001). PAE was less efficient regarding improvements in all functional parameters assessed including maximum urinary flow, post void residual, and reduction of prostate volume. In contrast, patient-reported erectile function (International Index of Erectile Function 5) was better after PAE and significantly fewer adverse events occurred after PAE.Moderately strong evidence confirms efficacy and safety of PAE in the treatment of BPH-LUTS in the short term. Significant advantages regarding safety and sexual function, but clear disadvantages regarding all other patient-reported and functional outcomes were found for PAE. Large-scale randomized controlled trials including longer follow-up periods are mandatory before PAE can be considered as a standard therapy and to define the ideal indication for PAE in the management of BPH-LUTS.We reviewed the role of prostatic artery embolization (PAE) in the treatment of symptoms associated with benign overgrowth of the prostate. The results suggest that PAE is not as effective as established surgical therapies but has fewer side effects. Further research is required to determine whether PAE is the best treatment for certain types of patients. PAE should, therefore, not yet be considered a standard treatment.

Background Acquired haemophilia (AH) is a rare bleeding disorder with significant morbidity and mortality. Most patients initially present to physicians without experience of the disease, delaying diagnosis and potentially worsening outcomes. Existing guidance in AH is limited to clinical opinion of few experts and does not address monitoring bleeds in specific anatomical locations. Aim Derive consensus from a large sample of experts around the world in monitoring bleeding patients with AH. Methods Using the Delphi methodology, a structured survey, designed to derive consensus on how to monitor bleeding patients with AH, was developed by a steering committee for completion by a group of haematologists with an interest in AH. Consensus was defined as ≥75% agreement with a given survey statement. After three rounds of survey refinement, a final list of consensus statements was compiled. Results Thirty-six global specialists in AH participated. The participants spanned 20 countries and had treated a median of 12.0 (range, 1-50) patients with AH within the preceding 5 years. Consensus was achieved in all items after three survey rounds. In addition to statements on general management of bleeding patients, consensus statements in the following areas were presented: urinary tract, gastrointestinal tract, muscles, skin, joints, nose, pharynx, mouth, intracranial and postpartum. Conclusions Here, we present consensus statements derived from a broad sample of global specialists to address monitoring of location-specific bleeds and evaluating efficacy of bleeding treatment in patients with AH. These statements could be applied in practice by treating physicians and validated by individual population surveys.

Essential thrombocythemia (ET) and polycythemia vera (PV) are myeloproliferative neoplasms (MPNs) characterized by an increased risk of developing venous and arterial thromboses and of evolution to myelofibrosis or acute leukemia (1). MPNs are recognized as a major cause of splanchnic vein thromboses (SVT), which include hepatic, splenic, portal and mesenteric vein thromboses (2). Patients with SVT are at an increased risk of developing bleeding events and arterial thrombotic events (3), as well as recurrent SVT and the use of anticoagulation and cytoreduction do not clearly modify this risk (3–5). Management of SVT in MPN patients remains a challenge and most therapeutic recommendations are based on retrospective analyses (6). Recently, De Stefano reported that hydroxyurea failed to prevent recurrent thromboses in the splanchnic vasculature in patients with a prior SVT (7). We conducted a prospective, open-label, multi-center phase II clinical trial of Pegylated Interferon Alfa-2a (PEG) in 20 subjects with SVT and an MPN, who represented a cohort of patients who participated in the Myeloproliferative Disorders - Research Consortium (MPD-RC) 111 trial (). MPD-RC 111 was a prospective study of patients with high-risk ET/PV who were resistant or intolerant to hydroxyurea (HU), but prior HU therapy was not a requirement for patients to enter the SVT cohort. Here we report the outcomes of the 20 SVT patients who were treated with PEG.

Background Medication errors are estimated to cost $42 billion in annual global treatment costs. Pharmacy-based Patient Safety Organizations (PSO) are tasked with collecting and analyzing incidents, near misses, and unsafe condition reports as one way of engaging pharmacies in quality improvement efforts. Collectively, these reports are referred to as quality related events (QREs). Large-scale analysis of typed narratives from QRE reports across organizations has been a missing component of quality improvement programs. Objective To identify topics within the components of a proposed medication safety event framework contained in the free-text narrative of QRE reports. Methods A retrospective, observational analysis of data from a PSOs voluntary reporting system, from January 1, 2011 to December 31, 2014. The dataset contained structured and unstructured data elements. A structural topic model extracted themes from the free-text narrative component of the report. These topics were assigned a human label and mapped onto constructs of the medication safety event framework. Results A total of 531,555 QREs were analyzed from 1660 pharmacies. 90.6% were near miss and unsafe condition reports. There were 40 topics generated. There were 29 topics identified as QRE types, 3 were identified as contributing factors, and 5 were related to signals/alerts that an incident or near miss had occurred. One topic each was identified as a recovery step and a quality improvement strategy. One topic was not assigned a human label. Examples of topics labeled included incorrect tapering directions, needing to double-check work, and attention-related contributing factor. Conclusions The free-text narrative provided novel information compared to the structured fields of the reports. Topics were mapped onto a proposed medication safety event framework to advance knowledge of medication QREs and identify ways to improve medication safety in community pharmacy. Future work may focus on communicating these topics to the pharmacies to improve medication safety efforts.

Essentials Long-term recurrence risk after a first unprovoked VTE with negative d-dimer levels is uncertain. Anticoagulation was stopped if d-dimer was negative, and was continued if d-dimer was positive. Five years after stopping anticoagulants, recurrent VTE was 30% in men and 17% in women. Negative d-dimers do not justify stopping anticoagulants in most men but appear to in most women. BACKGROUND The long-term risk of recurrence in patients with a first unprovoked venous thromboembolism (VTE) who have negative d-dimer results is uncertain. OBJECTIVES To determine this risk, including in subgroups based on sex. PATIENTS AND METHODS ln a prospective interventional cohort study of 410 patients with a first unprovoked VTE, anticoagulants were stopped if d-dimer was negative on therapy and 1 month after stopping therapy. Other patients remained on anticoagulant therapy. We previously reported findings after a mean of 2.2 years. The current report includes 3 years of additional follow-up in 293 of these patients. RESULTS During a median follow-up of 5.0 years, recurrent VTE after stopping therapy in response to negative d-dimer testing was 5.1% (95% confidence interval [CI], 3.6-6.5) per patient-year overall, 7.5% (95% CI, 5.5-10.0) in men, 3.8% (95% CI, 2.0-6.6) in women with VTE not associated with estrogens, and 0.4% (95% CI, 0.0-2.3) in women with VTE associated with estrogens (P

We aimed to systematically assess the evidence on the efficacy and safety of alpha-blockers in patients with multiple sclerosis (MS) suffering from neurogenic lower urinary tract dysfunction (NLUTD).The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement was used to perform this systematic review. An electronic search of Cochrane register, Embase, Medline, Scopus (last search 3 March 2018) and screening of reference lists as well as reviews were used to identify the studies. Articles were included if they reported on efficacy/safety of alpha-blockers for the treatment of NLUTD in patients with MS.After screening of 7'015 abstracts, three studies enrolling a total of 50 patients were included: one randomized, placebo-controlled, single-blind trial and two prospective cohort studies. Alpha-blocker treatment was successful in 50% to 96% of the patients. Pooling data from the three included studies, the relative risk for successful alpha-blocker treatment was 3.89 (95% confidence interval 2.7-7.0). The general safety profile of alpha-blockers was favorable with 8% of the patients reporting adverse events.Alpha-blockers may be effective and safe for treating NLUTD in female and male patients with MS but the studies were small and the overall quality of evidence was low. To make definitive conclusions, well designed randomized controlled trials are highly warranted.

Factor VIII protein (FVIII) as a coagulation replacement factor has for decades been used as the standard of care for management of people with haemophilia A. It is effective for treatment of bleeding events, as prophylaxis to prevent bleeding events and preserve joint function, and to support surgery in people with haemophilia A. Despite long experience in treating haemophilia A, we are only beginning to understand the functions of FVIII beyond its established role as a coenzyme to factor IXa to expedite thrombin generation through the intrinsic pathway of coagulation. Here, we review the current role of FVIII coagulant (FVIII:C) in haemophilia A management and emerging evidence for the role of FVIII across multiple systems, including the cardiovascular system, angiogenesis and maintenance of bone health. For instance, supraphysiological FVIII levels are a risk factor for venous thromboembolism. von Willebrand factor (VWF), which forms a non-covalent complex with circulating FVIII, is an established marker and regulator of angiogenesis. In a mouse model of haemophilia, treatment with FVIII decreased expression of receptor activator of nuclear factor kappa-Β ligand (RANKL), a marker for bone turnover. Longitudinal follow-up data in people with haemophilia A are needed to confirm and extend these observations.

The endosomal system is a highly dynamic multifunctional organelle, whose complexity is regulated in part by reversible ubiquitylation. Despite the wide-ranging influence of ubiquitin in endosomal processes, relatively few enzymes utilizing ubiquitin have been described to control endosome integrity and function. Here we reveal the deubiquitylating enzyme (DUB) ubiquitin-specific protease 32 (USP32) as a powerful player in this context. Loss of USP32 inhibits late endosome (LE) transport and recycling of LE cargos, resulting in dispersion and swelling of the late compartment. Using SILAC-based ubiquitome profiling we identify the small GTPase Rab7—the logistical centerpiece of LE biology—as a substrate of USP32. Mechanistic studies reveal that LE transport effector RILP prefers ubiquitylation-deficient Rab7, while retromer-mediated LE recycling benefits from an intact cycle of Rab7 ubiquitylation. Collectively, our observations suggest that reversible ubiquitylation helps switch Rab7 between its various functions, thereby maintaining global spatiotemporal order in the endosomal system., Though ubiquitin is known to broadly influence endosomal trafficking, few ubiquitin-utilizing enzymes targeting endosomal regulators are known. Here, the authors find that the deubiquitylating enzyme (DUB) USP32 influences endosomal membrane dynamics by deubiquitinating Rab7.

The colonic epithelium facilitates host–microorganism interactions to control mucosal immunity, coordinate nutrient recycling and form a mucus barrier. Breakdown of the epithelial barrier underpins inflammatory bowel disease (IBD). However, the specific contributions of each epithelial-cell subtype to this process are unknown. Here we profile single colonic epithelial cells from patients with IBD and unaffected controls. We identify previously unknown cellular subtypes, including gradients of progenitor cells, colonocytes and goblet cells within intestinal crypts. At the top of the crypts, we find a previously unknown absorptive cell, expressing the proton channel OTOP2 and the satiety peptide uroguanylin, that senses pH and is dysregulated in inflammation and cancer. In IBD, we observe a positional remodelling of goblet cells that coincides with downregulation of WFDC2—an antiprotease molecule that we find to be expressed by goblet cells and that inhibits bacterial growth. In vivo, WFDC2 preserves the integrity of tight junctions between epithelial cells and prevents invasion by commensal bacteria and mucosal inflammation. We delineate markers and transcriptional states, identify a colonic epithelial cell and uncover fundamental determinants of barrier breakdown in IBD. Profiling of single epithelial cells in healthy and inflamed colons identifies specialized cellular subpopulations, including a type of goblet cell that secretes the antibacterial protein WFDC2, which preserves the integrity of the epithelial barrier layer.

OBJECTIVES To evaluate the possible influence of non-pharmacological interventions, such as compressive bandages and intermittent pneumatic compression (IPC), on leg oedema and nocturnal polyuria (NP), and the possible interrelation between both pathologies in patients with spinal cord injury (SCI), as patients with SCI often have leg oedema and during the night the oedema decreases as a result of natural drainage mechanisms that can cause NP. PATIENTS AND METHODS Patients with SCI who followed their first rehabilitation after their SCI with bilateral leg oedema and/or with as much or a larger urine volume at night as during the day. The patients were all wheelchair users and followed the rehabilitation programme daily for 3 weeks. In all, 24 patients, aged between 21 and 63 years, were selected for participation in the 3-week rehabilitation programme. During the first week, baseline data were collected. During the second week, IPC was executed from the moment the patient went to lie down. During the third week, the patients wore multilayer compressive bandages. Leg circumference was measured in the morning before sitting up and at the moment they went to lie down in bed. During each study week, a daily frequency-volume chart (24 h) was completed. RESULTS The leg volume of both legs was significantly different between the morning and evening (right leg F = 103.90, P

OBJECTIVES To perform a post-hoc analysis of in-hospital costs incurred in a randomized controlled trial comparing prostatic artery embolization (PAE) and transurethral resection of the prostate (TURP). PATIENTS AND METHODS In-hospital costs arising from PAE and TURP were calculated using detailed expenditure reports provided by the hospital accounts department. Total costs including those arising from surgical and interventional procedures, consumables, personnel, and accommodation were analysed for all of the study participants and compared between PAE and TURP using descriptive analysis and two-sided t-tests adjusted for unequal variance within groups (Welch t-test). RESULTS Mean total costs per patient (± SD) were higher for TURP at €9,137 ± 3,301 than for PAE at €8,185 ± 1,630. The mean difference (md) of €952 was not statistically significant (p=0.07). While the mean procedural costs were significantly higher for PAE (md €623 (p=0.009)), costs apart from the procedure were significantly lower for PAE with an md of €1,627 (p< 0.001). Procedural costs of €1,433 ± 552 for TURP were mainly incurred by anaesthesia, whereas €2,590 ± 628 for medical supplies were the main cost factor for PAE. CONCLUSIONS Since in-hospital costs are similar but PAE and TURP have different efficacy and safety profiles, the patient's clinical condition and expectations - rather than finances - should be taken into account when deciding between PAE and TURP.

Aims To systematically assess all available evidence on efficacy and safety of desmopressin for treating nocturia in patients with multiple sclerosis (MS). Methods This systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Studies were identified by electronic search of Cochrane register, Embase, Medline, Scopus (last search March 3, 2018) and by screening of reference lists and reviews. Results After screening of 7015 abstracts, 8 prospective, and 1 retrospective studies were included enrolling a total of 178 patients. The mean patient age ranged between 43 and 51 years. A significant decrease in the number of micturitions per night was reported in 5 studies. An increase in the maximum hours of uninterrupted sleep was only found in two studies. A significant reduction of the volume of nocturnal incontinence was described in one study. The patient satisfaction rates ranged from 56% to 82%. The rate of adverse events was between 0% and 57.9%. The rate of hyponatremia ranged from 0% to 23.5% and other commonly reported adverse events were headache, nausea, fluid retention, rhinitis/epistaxis, malaise, and swollen ankles. Risk of bias and confounding was relevant in all studies. Conclusions Preliminary data suggest that desmopressin might be effective for treating nocturia in patients with MS. However, adverse events are relatively common, the overall quality of evidence is low and the number of studied patients is very limited. Further studies with newer formulations of desmopressin are highly warranted.

Background. The prediction of functional outcomes after spinal cord injury (SCI) is essential to plan the rehabilitation phase and the social reintegration. Recently, 2 models to predict independent and reliable bowel management 1 year after traumatic SCI have been derived and validated in 2 cohorts of patients included in the European Multicenter Study about Spinal Cord Injury (EMSCI). Objective. We aimed to validate 2 prediction models for bowel outcome after traumatic SCI in a patient sample external to EMSCI. Methods. The simplified model (based on a single predictor, the International Standards for Neurological Classification of Spinal Cord Injury [ISNCSCI] total motor score) and the full model (based on 2 predictors, the ISNCSCI total motor score and item 3a of the Spinal Cord Independence Measure) were applied to the retrospectively collected data of 111 patients with traumatic SCI. Results. The simplified and the full models showed excellent discrimination with an area under the receiver operating characteristic curve of .939 (95% confidence interval (CI) .87-1.00) and .922 (95% CI 0.85-.99), respectively. Both models displayed similar results for sensitivity and negative predictive values; however, the simplified model showed higher values for specificity, positive predictive values, and accuracy. The calibration analysis showed a partial overlap between predicted probabilities and observed proportion, with better and acceptable calibration for the simplified model. Conclusions. Using an independent sample, our study demonstrates the validity of a simple model to predict independent and reliable bowel management 1 year after traumatic SCI.
