Retrospective Cohort Study: Scope for Improvement-Barriers to Post-Polypectomy Surveillance in the Integrated Technologies for Improved Polyp Surveillance Cohort.

Background: Adherence to post-polypectomy surveillance is poor despite evidence that it is associated with lower risk of future colorectal cancer.

Methods: We evaluated 6,210 bowel screening participants between 2009-2016 in NHS Greater Glasgow and Clyde to assess potential barriers to post-polypectomy surveillance.

Results: Increasing deprivation (Scottish Index of Multiple Deprivation quintile 1 vs 5; OR 1.

Rapid, Inexpensive Multiplex Pathogen Detection Using Resequencing Microarrays.

Humanity faces an ongoing battle at the microscopic level to identify, contain, and treat outbreaks of numerous pathogens each year. Global genomic surveillance is the first step in monitoring outbreaks, but high-throughput methods are expensive and time-consuming. To solve this problem, we designed and manufactured a resequencing microarray capable of identifying 35 viral pathogens, 21 pathogenic bacteria, 16 antibiotic resistance genes, and 6 controls.

Impact of Lookback Duration on the Performance of a Claims-Based Frailty Proxy in Women With Stage I-III Breast Cancer.

Background: Frailty is an important prognostic indicator in older women with breast cancer. The Faurot frailty index, a validated claims-based frailty proxy measure, uses healthcare billing codes during a user-specified ascertainment window to predict frailty. We assessed how the duration of frailty ascertainment affected the ability of the Faurot frailty index to predict one-year mortality in women with stage I-II breast cancer.

Synthesis estimators for transportability with positivity violations by a continuous covariate.

Studies intended to estimate the effect of a treatment, like randomized trials, may not be sampled from the desired target population. To correct for this discrepancy, estimates can be transported to the target population. Methods for transporting between populations are often premised on a positivity assumption, such that all relevant covariate patterns in one population are also present in the other.

Lyme neuroborreliosis in Japan: Borrelia burgdorferi sensu lato as a cause of meningitis of previously undetermined etiology in hospitalized patients outside of the island of Hokkaido, 2010-2021.

Background And Purpose: Clinical manifestations of Lyme borreliosis (LB), caused by Borrelia burgdorferi sensu lato (Bbsl), include erythema migrans, Lyme neuroborreliosis (LNB), carditis, and arthritis. LB is a notifiable disease in Japan with <30 surveillance-reported LB cases annually, predominately from Hokkaido Prefecture. However, LB, including LNB, may be under-diagnosed in Japan since diagnostic tests are not readily available.
