Foreign-born immigrants are at high risk for latent TB infection (LTBI). In conjunction with the Baltimore City Health Department (BCHD), student volunteers conducted intensified LTBI case-finding (ICF) using tuberculin skin testing (TST) in the Hispanic community from 2006-2010. We sought to determine the yield of ICF and estimate the LTBI prevalence. Retrospective cross-sectional study. Among 478 individuals screened, 164 (34.3 %) had a positive TST, 227 (47.5 %) had a negative TST, and 87 (18.2 %) did not return. Among those who completed screening, the prevalence of LTBI was 164/391 (41.9, 95 % CI 0.37-0.47). ICF referrals accounted for 4.4 % of all LTBI referrals to BCHD and for 41 % of referrals among Hispanics. We found a high rate of undiagnosed LTBI within the Hispanic community. This student-run ICF program accounted for almost half of all LTBI cases among Hispanics. Community resources are needed to target this high-risk population.

Governance Considerations for Point-of-Care Ultrasound: a HIMSS-SIIM Enterprise Imaging Community Whitepaper in Collaboration with AIUM.
J Imaging Inform Med

Independent Consultant, Kirkland, WA, USA.
Point-of-care ultrasound (POCUS) has emerged as a standard of care across a variety of healthcare settings due to its ability to provide critical clinical information and as well as procedural guidance to clinicians directly at the bedside. Implementation of enterprise imaging (EI) strategies is needed such that POCUS images can be appropriately captured, indexed, managed, stored, distributed, viewed, and analyzed. Because of its unique workflow and educational requirements, reliance on traditional order-based workflow solutions may be insufficient.

Objective: We sought to develop a machine learning (ML) preoperative model to predict bile leak following hepatectomy for primary and secondary liver cancer.
Methods: An eXtreme Gradient Boosting (XGBoost) model was developed to predict post-hepatectomy bile leak using data from the ACS-NSQIP database. The model was externally validated using data from hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC) multi-institutional databases.
Patellar Instability After Total Knee Arthroplasty.

Patellar instability following total knee arthroplasty (TKA) is a rare, yet serious complication, potentially requiring revision surgery or resulting in chronic dysfunction. When encountered, it is paramount to understand the etiologies, diagnostic approaches, treatment options, and outcomes of the selected treatment. The most common cause of patella instability is improper positioning of components, leading to lateral maltracking of the patella.

Objective: Malalignment following cervical spine deformity (CSD) surgery can negatively impact outcomes and increase complications. Despite the growing ability to plan alignment, it remains unclear whether preoperative goals are achieved with surgery. The objective of this study was to assess how good surgeons are at achieving their preoperative goal alignment following CSD surgery.

This companion study assesses the effect of these regimens on patient-reported outcomes (PROs). Using the Lee Chronic GVHD Symptom Score and PROMIS subscales (physical function, GI symptoms, social role satisfaction) as primary end points and hemorrhagic cystitis symptoms and Lee subscales as secondary end points, responses from English and Spanish speakers were analyzed at baseline and days 100, 180, and 365 after transplant.
