The study objective was to evaluate combined endoscopic and robotic surgery, a novel surgical technique modifying traditional combined endoscopic laparoscopic surgery through robotic assistance, and characterize a series of patients who underwent the modified operative technique. A retrospective case series was performed. The first thirty-seven consecutive patients who underwent combined endoscopic robotic surgery by a single colorectal surgeon from March 2018 to October 2019 were included. Main outcome measures included operative time, intra-operative complication, 30-day post-operative complication, and hospital length of stay. Combined endoscopic and robotic surgery was performed in 37 cases, 32 (86.5%) of which saw the technique through to completion. Median operative room time was 73 min (range 31–184 min). No intraoperative complications occurred and 2 (6.3%) experienced 30-day post-operative complications. Median hospital length of stay was 1.1 days (range 0.2–2.0 days). Median polyp size was 35 mm (range 20–130 mm). Polyps were resected from the following locations: cecum (37.5%), ascending colon (28.1%), transverse colon (21.9%), descending colon (3.1%), sigmoid colon (6.3%), and rectum (3.1%). Pathology demonstrated 77.4% tubular adenoma, 12.9% sessile serrated adenoma, 6.5% dysplasia, and 3.2% signet cell adenocarcinoma. Combined endoscopic robotic surgery was associated with decreased operative time, complication rates, and hospital length of stay compared to literature-reported statistics for combined endoscopic laparoscopic surgery. Increased confidence with 3-dimensional visualization and intracorporeal suturing using combined endoscopic and robotic surgery was noted. Additional studies are needed to further define the role of robotics in combined endoscopic surgery.

OBJECTIVES: Emergency department (ED) hepatitis C virus (HCV) screening programs are proliferating, and it is unknown whether EDs are more effective than traditional community screening at promoting HCV follow-up care. The objective of this study was to investigate whether patients screened HCV seropositive (HCV+) in the ED are linked to care and retained in treatment more successfully than patients screened HCV+ in the community. METHODS: A retrospective cohort study was performed including patients screened HCV+ at twelve screening facilities in xx, xx from March 1, 2015 to July 31, 2017. Treatment outcomes, including retention and time to follow-up care, were assessed using the HCV continuum of care model. RESULTS: ED patients (n=3,008) were significantly more likely to achieve RNA confirmation (aRR=1.91, 95% CI=1.54–2.37), initiate HCV therapy (aRR=2.23 [1.76–2.83]), complete HCV therapy (aRR=1.77 [1.40–2.24]), and achieve HCV functional cure (aRR=2.80 [1.09–7.23]) compared to community-screened patients (n=322). ED screening was associated with decreased likelihood of fibrosis staging (aRR=0.65 [0.51–0.82]) and no difference in linkage to specialty care (aRR=1.03 [0.69–1.53]). In time to follow up, RNA confirmation occurred at faster rates in the ED (aHR=2.26 [1.86–2.72]), although these patients completed fibrosis staging at slower rates (aHR=0.49 [0.38–0.63]) than community patients. CONCLUSIONS: Compared to community screening, HCV screening in the ED was associated with higher rates of disease confirmation, treatment initiation/completion, and cure. Our findings provide new evidence that EDs may be the most effective setting to screen patients for HCV to promote follow-up care.

The hepatitis C virus (HCV) treatment landscape is shifting given the advent of direct-acting antivirals and a global call to action by the World Health Organization. Eliminating HCV is now an issue of healthcare delivery. Treatment is limited by the complexity of the HCV care continuum, expensive therapy and competing health burdens experienced by an underserved HCV population. The objective of this literature review was to assess strategies to improve retention in HCV care, with particular focus on those implemented in the United States. We identified barriers in HCV care retention and propose solutions to increase HCV treatment delivery. The following recommendations are herein described: improving the cohesion of health services through localized care and integrated case management, expanding the supply of non-specialist HCV treatment providers, leveraging patient navigators and care coordinators, improving adherence through directly observed therapy and reducing cost barriers through value-based payment and pharmaceutical subscription models.

BACKGROUND Trichomoniasis commonly affects women of childbearing age and has been linked to several adverse birth outcomes. OBJECTIVE To elucidate the association between trichomoniasis in pregnant women and adverse birth outcomes, including preterm delivery, prelabour rupture of membranes and low birthweight. SEARCH STRATEGY MEDLINE, EMBASE and ClinicalTrials.gov were systematically searched in December 2020 without time or language restrictions. SELECTION CRITERIA Original research studies were included if they assessed at least one of the specified adverse birth outcomes in pregnant women with laboratory-diagnosed trichomoniasis. DATA COLLECTION AND ANALYSIS Estimates from included articles were either extracted or calculated and then pooled to produce a combined estimate of the association of trichomoniasis with each adverse birth outcome using the random effects model. Heterogeneity was assessed using the I2 statistic and Cochran's Q test. MAIN RESULTS Literature search produced 1658 publications after removal of duplicates (n = 770), with five additional publications identified by hand search. After screening titles and abstracts for relevance, full text of 84 studies was reviewed and 19 met inclusion criteria for meta-analysis. Significant associations were found between trichomoniasis and preterm delivery (OR 1.27; 95% CI 1.08-1.50), prelabour rupture of membranes (OR 1.87; 95% CI 1.53-2.29) and low birthweight (OR 2.12; 95% CI 1.15-3.91). CONCLUSIONS Trichomoniasis in pregnant women is associated with preterm delivery, prelabour rupture of membranes and low birthweight. Rigorous studies are needed to determine the impact of universal trichomoniasis screening and treatment during pregnancy on reducing perinatal morbidity. TWEETABLE ABSTRACT This systematic review and meta-analysis found that in the setting of pregnancy, trichomoniasis is significantly associated with multiple adverse birth outcomes, including preterm delivery, low birthweight, and prelabour rupture of membranes.

BACKGROUND: People experiencing homelessness are disproportionately infected with human immunodeficiency virus (HIV) and hepatitis C virus (HCV). In response to COVID-19, cities nationwide temporarily housed people experiencing homelessness in unused hotels. One such initiative in New Orleans also enacted a screening, counseling, and linkage-to-care model for HIV and HCV treatment for this temporarily housed population between May and July 2020. METHODS: A non-concurrent cohort study was performed assessing follow up in the treatment of HIV and HCV for this population. Outcome data was collected on seropositive patients' electronic medical record to assess patient progression through the treatment cascade. RESULTS: Of 102 unhoused residents, 25 (24.5%) tested HCV seropositive. Of the HCV positive 21/25 (84%) were connected to the associated clinic for follow up care and 10 (40%) obtained HCV treatment medication. Furthermore, all three patients who tested seropositive for HIV either started or re-initiated anti-viral treatment. The greatest barrier to providing medication for the HCV seropositive patients, once care was initiated, was loss-to-follow-up. CONCLUSION: Targeting homeless persons living in temporary residences for HCV and HIV screening can be effective at promoting access to care for those infected due to this population's high HCV seropositivity especially significant if the patient has a history of intravenous drug use or is over the age of 40. However, continued outreach strategies are needed to assist patients in retention of care.

OBJECTIVES/SPECIFIC AIMS: The objective of this study is to assess differences in outcomes between African Americans (AAs) and whites along the HCV care cascade. Primary outcome was retention in the HCV care cascade, measured in two ways. For viral RNA confirmation, retention was a percentage of those having screened antibody reactive. For hepatic ultrasound, primary care, HCV specialty clinic, treatment initiation, and sustained viral load (SVR), retention was a percentage of those found chronically infected by positive RNA viral load. Secondary outcome was time to follow-up from antibody screening to each subsequent step in the care cascade. METHODS/STUDY POPULATION: A retrospective cohort study was performed. AA and white patients who tested HCV antibody reactive from March to October 2015 at the University Medical Center (UMC) Emergency Department in New Orleans, LA were included in this study. Outcomes were assessed using the HCV Continuum of Care model, delineating successive stages of care from identification to cure. RESULTS/ANTICIPATED RESULTS: A total of 728 patients screened HCV antibody reactive, including 446 AAs and 282 whites. AAs (53.5 years, SD 10.2) were disproportionately older than whites (46.7 years, SD 11.9) (p

Dramatic progress has been made in the design and build phases of the design-build-test cycle for engineering cells. However, the test phase usually limits throughput, as many outputs of interest are not amenable to rapid analytical measurements. For example, phenotypes such as motility, morphology, and subcellular localization can be readily measured by microscopy, but analysis of these phenotypes is notoriously slow. To increase throughput, we developed microscopy-readable barcodes (MiCodes) composed of fluorescent proteins targeted to discernible organelles. In this system, a unique barcode can be genetically linked to each library member, making possible the parallel analysis of phenotypes of interest via microscopy. As a first demonstration, we MiCoded a set of synthetic coiled-coil leucine zipper proteins to allow an 8 × 8 matrix to be tested for specific interactions in micrographs consisting of mixed populations of cells. A novel microscopy-readable two-hybrid fluorescence localization assay for probing candidate interactions in the cytosol was also developed using a bait protein targeted to the peroxisome and a prey protein tagged with a fluorescent protein. This work introduces a generalizable, scalable platform for making microscopy amenable to higher-throughput library screening experiments, thereby coupling the power of imaging with the utility of combinatorial search paradigms.
