RESUMO
The process of protein phase separation into liquid condensates has been implicated in the formation of membraneless organelles (MLOs), which selectively concentrate biomolecules to perform essential cellular functions. Although the importance of this process in health and disease is increasingly recognized, the experimental identification of proteins forming MLOs remains a complex challenge. In this study, we addressed this problem by harnessing the power of AlphaFold2 to perform computational predictions of the conformational properties of proteins from their amino acid sequences. We thus developed the CoDropleT (co-condensation into droplet transformer) method of predicting the propensity of co-condensation of protein pairs. The method was trained by combining experimental datasets of co-condensing proteins from the CD-CODE database with curated negative datasets of non-co-condensing proteins. To illustrate the performance of the method, we applied it to estimate the propensity of proteins to co-condense into MLOs. Our results suggest that CoDropleT could facilitate functional and therapeutic studies on protein condensation by predicting the composition of protein condensates.

Chronic hepatitis B virus (HBV) infection is an incurable global health threat responsible for causing liver disease and hepatocellular carcinoma. During the genesis of infection, HBV establishes an independent minichromosome consisting of the viral covalently closed circular DNA (cccDNA) genome and host histones. The viral X gene must be expressed immediately upon infection to induce degradation of the host silencing factor, Smc5/6. However, the relationship between cccDNA chromatinization and X gene transcription remains poorly understood. Establishing a reconstituted viral minichromosome platform, we found that nucleosome occupancy in cccDNA drives X transcription. We corroborated these findings in cells and further showed that the chromatin destabilizing molecule CBL137 inhibits X transcription and HBV infection in hepatocytes. Our results shed light on a long-standing paradox and represent a potential new therapeutic avenue for the treatment of chronic HBV infection.
RESUMO
Currently available references provide evidence on efficacy of probiotics strains but exclude product-specific information, making it challenging for healthcare professionals (HCPs) to provide suitable probiotic recommendations to consumers. This study describes the development and evaluation of an online probiotics e-reference database to assist HCPs in delivering evidence-based recommendations on probiotics to consumers. The database currently consists of 556 clinical studies collated through PubMed literature search, 753 probiotic products from multiple retail stores in Singapore and 5708 unique product-study links. Users can search for probiotics based on indication, product or strain. Based on a pilot evaluation by 25 pharmacists practising in hospital and retail settings, 84% agreed that the database helped in assessing the efficacy of probiotic products. All (100%) found the database easy to navigate and most (96%) would continue to use the database as an evidence-based e-reference for probiotic information.

Importance: Patient safety interventions, like the World Health Organization Surgical Safety Checklist, require effective implementation strategies to achieve meaningful results. Institutions with underperforming checklists require evidence-based guidance for reimplementing these practices to maximize their impact on patient safety. Objective: To assess the ability of a comprehensive system of safety checklist reimplementation to change behavior, enhance safety culture, and improve outcomes for surgical patients. Design, Setting, and Participants: This prospective type 2 hybrid implementation-effectiveness study took place at 2 large academic referral centers in Singapore. All operations performed at either hospital were eligible for observation. Surveys were distributed to all operating room staff. Intervention: The study team developed a comprehensive surgical safety checklist reimplementation package based on the Exploration, Preparation, Implementation, Sustainment framework. Best practices from implementation science and human factors engineering were combined to redesign the checklist. The revised instrument was reimplemented in November 2021. Main Outcomes and Measures: Implementation outcomes included penetration and fidelity. The primary effectiveness outcome was team performance, assessed by trained observers using the Oxford Non-Technical Skills (NOTECH) system before and after reimplementation. The Agency for Healthcare Research and Quality Hospital Survey on Patient Safety Culture was used to assess safety culture and observers tracked device-related interruptions (DRIs). Patient safety events, near-miss events, 30-day mortality, and serious complications were tracked for exploratory analyses. Results: Observers captured 252 cases (161 baseline and 91 end point). Penetration of the checklist was excellent at both time points, but there were significant improvements in all measures of fidelity after reimplementation. Mean NOTECHS scores increased from 37.1 to 42.4 points (4.3 point adjusted increase; 95% CI, 2.9-5.7; P < .001). DRIs decreased by 86.5% (95% CI, -22.1% to -97.8%; P = .03). Significant improvements were noted in 9 of 12 composite areas on culture of safety surveys. Exploratory analyses suggested reductions in patient safety events, mortality, and serious complications. Conclusions and Relevance: Comprehensive reimplementation of an established checklist intervention can meaningfully improve team behavior, safety culture, patient safety, and patient outcomes. Future efforts will expand the reach of this system by testing a structured guidebook coupled with light-touch implementation guidance in a variety of settings.

The phenomenon of protein phase separation (PPS) underlies a wide range of cellular functions. Correspondingly, the dysregulation of the PPS process has been associated with numerous human diseases. To enable therapeutic interventions based on the regulation of this association, possible targets should be identified. For this purpose, we present an approach that combines the multiomic PandaOmics platform with the FuzDrop method to identify PPS-prone disease-associated proteins. Using this approach, we prioritize candidates with high PandaOmics and FuzDrop scores using a profiling method that accounts for a wide range of parameters relevant for disease mechanism and pharmacological intervention. We validate the differential phase separation behaviors of three predicted Alzheimer's disease targets (MARCKS, CAMKK2, and p62) in two cell models of this disease. Overall, the approach that we present generates a list of possible therapeutic targets for human diseases associated with the dysregulation of the PPS process.

INTRODUCTION: With growing emphasis on surgical safety, it appears fundamental to assess the safety of colorectal resection involving primary stapled anastomosis. Surgical stapling devices can considerably foster patient safety in colorectal surgery, but their misuse or malfunction encompass a unique risk of postoperative complications. The Digital Device Briefing Tool (DDBT) is a digital cognitive aid developed to enhance safe use of the Ethicon circular stapling device during colorectal resection. The purpose of this study is to evaluate how a digital operative workflow, including DDBT, compared with routine surgical care, affects morbidity and mortality in patients undergoing left-sided colorectal resection with primary stapled colorectal anastomosis for colorectal cancer or benign disease. METHODS AND ANALYSIS: A multicentre, prospective cohort study will be conducted at five certified academic colorectal centres in Germany. It compares a non-digital with a Johnson & Johnson digital solution (Surgical Process Institute Deutschland (SPI))-guided operative workflow in patients undergoing left hemicolectomy, sigmoidectomy, anterior rectal resection and Hartmann reversal procedure. The sample size is set at 528 cases in total, divided into 3 groups (a non-digital and two SPI-guided workflow cohorts, with and without DDBT) in a ratio of 1:1:1, with 176 patients each. The primary endpoint is a composite outcome comprising the overall rate of surgical complications, including death, during hospitalisation and within the first 30 days after colorectal resection. Secondary endpoints include operating time, length of hospital stay and 30-day hospital readmission rate. ETHICS AND DISSEMINATION: This study will be performed in line with the Declaration of Helsinki. The ethics committee of the Charité-University Medicine Berlin, Germany, approved the study (No: 22-0277-EA2/060/22). Study Investigators will obtain written informed consent from each patient before a patient may participate in this study. The study results will be submitted to an international peer-reviewed journal. TRIAL REGISTRATION NUMBER: DRKS00029682.

Pancreatic cancer has the worst prognosis of all common tumors. Earlier cancer diagnosis could increase survival rates and better assessment of metastatic disease could improve patient care. As such, there is an urgent need to develop biomarkers to diagnose this deadly malignancy earlier. Analyzing circulating extracellular vesicles (cEVs) using 'liquid biopsies' offers an attractive approach to diagnose and monitor disease status. However, it is important to differentiate EV-associated proteins enriched in patients with pancreatic ductal adenocarcinoma (PDAC) from those with benign pancreatic diseases such as chronic pancreatitis and intraductal papillary mucinous neoplasm (IPMN). To meet this need, we combined the novel EVtrap method for highly efficient isolation of EVs from plasma and conducted proteomics analysis of samples from 124 individuals, including patients with PDAC, benign pancreatic diseases and controls. On average, 912 EV proteins were identified per 100µL of plasma. EVs containing high levels of PDCD6IP, SERPINA12 and RUVBL2 were associated with PDAC compared to the benign diseases in both discovery and validation cohorts. EVs with PSMB4, RUVBL2 and ANKAR were associated with metastasis, and those with CRP, RALB and CD55 correlated with poor clinical prognosis. Finally, we validated a 7-EV protein PDAC signature against a background of benign pancreatic diseases that yielded an 89% prediction accuracy for the diagnosis of PDAC. To our knowledge, our study represents the largest proteomics profiling of circulating EVs ever conducted in pancreatic cancer and provides a valuable open-source atlas to the scientific community with a comprehensive catalogue of novel cEVs that may assist in the development of biomarkers and improve the outcomes of patients with PDAC.
RESUMO
BACKGROUND: Interruptions in operative flow are known to increase team stress and errors in the operating room. Device-related interruptions are an increasing area of focus for surgical safety, but common safety processes such as the Surgical Safety Checklist do not adequately address surgical devices. We assessed the impact of the Device Briefing Tool, a communication instrument for surgical teams, on device-related interruptions in a large academic referral center in Singapore. METHODS: The Device Briefing Tool was implemented in 4 general surgery departments, with 4 additional departments serving as a comparator group. Trained observers evaluated device-related interruption incidence in live operations at baseline and after implementation. Changes in device-related interruption frequency were assessed in each group using Poisson regression, with and without adjustment for surgical department and device complexity. Subgroup analyses assessed the impact of the Device Briefing Tool by device type. RESULTS: A total of 210 operations were evaluated by observers. In the Device Briefing Tool group, there were 38.6 and 27.2 device-related interruptions per 100 cases at baseline and after Device Briefing Tool implementation, respectively (difference -23%, P = .0047, adjusted difference -28%, P = .0013). Device-related interruption frequency in the comparator group remained stable across study periods. Point estimates indicated reductions in device-related interruptions for all device types, reaching statistical significance for circular staplers (-26%, P = .0049). CONCLUSION: Implementation of the Device Briefing Tool was associated with a 28% reduction in device-related interruptions. Proactive approaches to improving surgical device safety are crucial in the technology-driven landscape of modern surgical care. Future efforts will assess formal integration of the Device Briefing Tool into institution-wide surgical safety processes.

INTRODUCTION: Clear communication around surgical device use is crucial to patient safety. We evaluated the utility of the Device Briefing Tool (DBT) as an adjunct to the Surgical Safety Checklist. METHODS: A nonrandomized, controlled pilot of the DBT was conducted with surgical teams at an academic referral center. Intervention departments used the DBT in all cases involving a surgical device for 10 wk. Utility, relative advantage, and implementation effectiveness were evaluated via surveys. Trained observers assessed adherence and team performance using the Oxford NOTECHS system. RESULTS: Of 113 individuals surveyed, 91 responded. Most respondents rated the DBT as moderately to extremely useful. Utility was greatest for complex devices (89%) and new devices (88%). Advantages included insight into the team's familiarity with devices (70%) and improved teamwork and communication (68%). Users found it unrealistic to review all device instructional materials (54%). Free text responses suggested that the DBT heightened awareness of deficiencies in device familiarity and training but lacked a clear mechanism to correct them. DBT adherence was 82%. NOTECHS scores in intervention departments improved over the course of the study but did not significantly differ from comparator departments. CONCLUSIONS: The DBT was rated highly by both surgeons and nurses. Adherence was high and we found no evidence of "checklist fatigue." Centers interested in implementing the DBT should focus on devices that are complex or new to any surgical team member. Guidance for correcting deficiencies identified by the DBT will be provided in future iterations of the tool.

BACKGROUND: Surgical devices are implicated in approximately 15% of intraoperative interruptions and 25% of errors. Device-related interruptions (DRIs) are therefore an important target for surgical quality improvement, but scalable measurement methodologies are lacking. The researchers therefore developed, pilot tested, and refined a simple tool for assessing intraoperative DRIs. METHODS: Five DRI categories achieved face validity with frontline providers and surgical safety experts: improper/challenging assembly, device failure, loss of sterility, disconnection, and absent/wrong device. A data collection tool was created based on these categories as well as a free-text section to capture emergent DRI categories. After a brief training session, the tool was pilot tested by observers at a large academic referral center. RESULTS: In a sample of 210 operations, observers noted 66 DRIs across 39 cases. DRIs were most common in colorectal (38.0 per 100 cases), gynecologic (33.3 per 100 cases), and hepatopancreatobiliary surgery (32.1 per 100 cases). Device failure accounted for 30.3% of observed DRIs. Three emergent categories were identified: user unfamiliarity with the device (15.2%), video display malfunction (4.5%), and physical breakage of the device (1.5%). CONCLUSION: Measurement of DRIs by novice observers is a feasible and scalable approach to support quality improvement efforts focusing on surgical devices. This approach could provide actionable insights to improve device safety, such as informing educational and training programs, optimizing surgical tray composition, and improving the physical layout of the operating room.

BACKGROUND: Non-technical skills are critical to surgical safety. We examined the impact of the COVID-19 pandemic on non-technical skills of operating room (OR) teams in Singapore. MATERIALS AND METHODS: Observers rated live operations using the Oxford NOTECHS system. Pre- and post-COVID observations were captured from November 2019 to January 2020 and from January 2021 to February 2021, respectively. Scores were compared using Schuirmann's Two One-Sided Test procedure. Multivariable linear regression was used to adjust for case mix. A 10% margin of equivalence was set a priori. RESULTS: Observers rated 159 cases: 75 pre-COVID and 84 post-COVID. There were significant differences between groups in surgical department and surgeon-reported case complexity (both P < 0.001). Total NOTECHS scores increased post-COVID on raw analysis (36.1 vs 38.0, P < 0.001) but remained within the margin of equivalence (90% CI 1.3 to 2.6, P < 0.001). Multivariable analysis demonstrated a similar increase within the margin of equivalence (2.0, 90% CI 1.3 to 2.7). Teamwork and cooperation scores increased by 1.0 post-COVID (90% CI 0.8 to 1.3); all other subcomponent scores were equivalent. CONCLUSION: Non-technical skills before and after the peak of the COVID-19 pandemic were equivalent but not equal. A small but statistically significant improvement post-COVID was driven by an increase in teamwork and cooperation skills. These findings may reflect an improvement in team cohesion, which has been observed in teams under duress in other settings such as the military. Future work should explore the effect of the pandemic on OR culture, team cohesion, and resilience.

PURPOSE: Pancreatic ductal adenocarcinoma (PDAC) remains a significant health issue. For most patients, there are no options for targeted therapy, and existing treatments are limited by toxicity. The HOPE trial (Harnessing Organoids for PErsonalized Therapy) was a pilot feasibility trial aiming to prospectively generate patient-derived organoids (PDO) from patients with PDAC and test their drug sensitivity and correlation with clinical outcomes. EXPERIMENTAL DESIGN: PDOs were established from a heterogeneous population of patients with PDAC including both basal and classical PDAC subtypes. RESULTS: A method for classifying PDOs as sensitive or resistant to chemotherapy regimens was developed to predict the clinical outcome of patients. Drug sensitivity testing on PDOs correlated with clinical responses to treatment in individual patients. CONCLUSIONS: These data support the investigation of PDOs to guide treatment in prospective interventional trials in PDAC.

Neurogenic thoracic outlet syndrome (NTOS) represents a disorder believed to involve compression of one or more neurovascular elements as they exit the thoracic outlet. This comprehensive literature review will focus on the occurrence, classification, etiology, clinical presentation, diagnostic measures, and both nonoperative and operative therapies for NTOS. NTOS represents the most common subtype of thoracic outlet syndrome and can significantly impair quality of life. Botulinum toxin injection into the anterior scalene muscle, or even the middle scalene or pectoralis minor muscles, can reduce the symptoms of this syndrome. The best available evidence for botulinum toxin therapy to the cervicothoracic muscles supports the value of this treatment for reducing pain in the affected extremity, and for an approximate duration of 2 months or more. Surgical approaches and newer minimally invasive surgical approaches offer high rates of improvement in select centers.
RESUMO
Degenerative spondylolisthesis is a common back pathology in the general adult population. Patients with this condition may present for epidural steroid injection, epidural blood patch, or epidural analgesia. We report five patients with degenerative spondylolisthesis who experienced inadvertent dural puncture during interlaminar epidural steroid injection attempts: four with intrathecal contrast spread or cerebrospinal backflow into the epidural needle and one with subdural contrast spread. Patients with degenerative spondylolisthesis may be at higher risk for dural puncture due to stretching of the dura and contraction of the epidural space at the translated spinal level. In the following report, we summarize the cases and suggest risk mitigation strategies for both chronic and acute pain physicians.

The exocrine pancreas, consisting of ducts and acini, is the site of origin of pancreatitis and pancreatic ductal adenocarcinoma (PDAC). Our understanding of the genesis and progression of human pancreatic diseases, including PDAC, is limited because of challenges in maintaining human acinar and ductal cells in culture. Here we report induction of human pluripotent stem cells toward pancreatic ductal and acinar organoids that recapitulate properties of the neonatal exocrine pancreas. Expression of the PDAC-associated oncogene GNASR201C induces cystic growth more effectively in ductal than acinar organoids, whereas KRASG12D is more effective in modeling cancer in vivo when expressed in acinar compared with ductal organoids. KRASG12D, but not GNASR201C, induces acinar-to-ductal metaplasia-like changes in culture and in vivo. We develop a renewable source of ductal and acinar organoids for modeling exocrine development and diseases and demonstrate lineage tropism and plasticity for oncogene action in the human pancreas.

BACKGROUND: ROP screening is vital in care of premature infants but is considered burdensome, difficult and time consuming for ophthalmologists. This study assessed the reduction in workload following the introduction of nurse-led WFDRI to a large neonatal nursery. METHODS: We report a retrospective audit of 628 infants screened for ROP in the years 2010, 2013 and 2019 at the Royal Women's Hospital, Victoria. The last complete year of screening for ROP using binocular indirect ophthalmoscopy (BIO) alone (2010) was compared with two subsequent years after the introduction of nurse-led WFDRI. The main outcome measures were the time taken to report and document WFDRI and the time taken to undertake BIO examination of a premature infant and document the results. RESULTS: The ophthalmologist's time taken to conduct BIO, review images and document the results per 100 patient examinations was reduced from 16.7 hours before introduction of WFDRI to 3.7 hours. Similarly, the weekly time spent on this component of ROP screening fell from 2.3 hours per week to 0.8 and 1.0 hours per week after introduction of WFDRI. CONCLUSIONS: The introduction of nurse-led WFDRI has resulted in a dramatic and sustained reduction in ophthalmologist workload involved in ROP screening in a large Australian neonatal nursery. This may result in improved retention of the ophthalmic workforce required to undertake ROP screening.

Patient-derived organoid models are proving to be a powerful platform for both basic and translational studies. Here we conduct a methodical analysis of pancreatic ductal adenocarcinoma (PDAC) tumor organoid drug response in paired patient-derived xenograft (PDX) and PDX-derived organoid (PXO) models grown under WNT-free culture conditions. We report a specific relationship between area under the curve value of organoid drug dose response and in vivo tumor growth, irrespective of the drug treatment. In addition, we analyzed the glycome of PDX and PXO models and demonstrate that PXOs recapitulate the in vivo glycan landscape. In addition, we identify a core set of 57 N-glycans detected in all 10 models that represent 50%-94% of the relative abundance of all N-glycans detected in each of the models. Last, we developed a secreted biomarker discovery pipeline using media supernatant of organoid cultures and identified potentially new extracellular vesicle (EV) protein markers. We validated our findings using plasma samples from patients with PDAC, benign gastrointestinal diseases, and chronic pancreatitis and discovered that 4 EV proteins are potential circulating biomarkers for PDAC. Thus, we demonstrate the utility of organoid cultures to not only model in vivo drug responses but also serve as a powerful platform for discovering clinically actionable serologic biomarkers.

BACKGROUND: Introducing new surgical devices into the operating room (OR) can serve as a critical opportunity to address patient safety. The effectiveness of OR briefings to improve communication, teamwork, and safety has not been evaluated in this setting. METHODS: Ariadne Labs and Johnson and Johnson (J&J) collaborated to develop and assess an intervention including a Device Briefing Tool (DBT) and novel multidisciplinary team training for clinicians (surgeons and nurses) around the introduction of a new device in the OR. J&J sales representatives trained clinicians to use the DBT, a communication tool to improve patient safety when a new device is used for the first time. Surveys were administered to representatives (n = 10), surgeons (n = 15), and nurses (n = 30) at the baseline, after trainings, and after using the DBT in an operation at six different Thai hospitals. RESULTS: Familiarity with the Surgical Safety Checklist (SURGICAL SAFETY CHECKLIST) varied but increased post-training. Regarding trainings, 90% of representatives felt they very much or completely met all learning objectives but 50% felt only slightly prepared to train clinicians on using DBT. Post-training, clinician confidence in using a new device rose from 47 to 85%. Regarding the DBT, 90% of clinicians felt confident using it and reported they were very likely to use it in the future. Overall, over 90% of all clinicians and representatives felt safe having surgery in their hospitals. CONCLUSIONS: There is high acceptability and feasibility of the multidisciplinary trainings and the DBT among representatives and clinicians, albeit in a limited number of participants from a small number of institutions.
