Article Synopsis
  • Deep learning (DL) can recognize intricate patterns in data that humans might miss, but it often leads to misleading results due to its black-box nature and a problem known as algorithmic shortcutting.
  • In a case study, simple convolutional neural networks (CNNs) were able to predict patient behaviors like avoiding refried beans or beer just by analyzing knee X-rays, showcasing the dangers of relying on shortcuts in data interpretation.
  • The findings highlight that the models' predictions are influenced by confounding factors in the images that cannot be easily eliminated, indicating a need for stricter criteria when assessing research involving medical imaging.

Objectives: To outline the procedural implementation and optimization of rapid diagnostic test (RDT) results for bloodstream infections (BSIs) and to evaluate the combination of RDTs with real-time antimicrobial stewardship team (AST) support plus clinical surveillance platform (CSP) software on time to appropriate therapy in BSIs at a single health system.

Methods: Blood culture reporting and communication were reported for four time periods: (i) a pre-BCID [BioFire® FilmArray® Blood Culture Identification (BCID) Panel] implementation period that consisted of literature review and blood culture notification procedure revision; (ii) a BCID implementation period that consisted of BCID implementation, real-time results notification via CSP, and creation of a treatment algorithm; (iii) a post-BCID implementation period; and (iv) a BCID2 implementation period. Time to appropriate therapy metrics was reported for the BCID2 time period.

The epigenome influences gene regulation and phenotypes in response to exposures. Epigenome assessment can determine exposure history aiding in diagnosis. Here we developed and implemented a machine learning algorithm, the exposure signature discovery algorithm (ESDA), to identify the most important features present in multiple epigenomic and transcriptomic datasets to produce an integrated exposure signature (ES).

Background: Osteoarthritic knee pain is a complex phenomenon, and multiple factors, both within the knee and external to it, can contribute to how the patient perceives pain. We sought to determine how well a deep neural network could predict osteoarthritic knee pain and other symptoms solely from a single radiograph view.

Methods: We used data from the Osteoarthritis Initiative, a 10-year observational study of patients with knee osteoarthritis.

Nutritive symbiosis between bacteria and ticks is observed across a range of ecological contexts; however, little characterization on the molecular components responsible for this symbiosis has been done. Previous studies in our lab demonstrated that Rickettsia monacensis str. Humboldt (strain Humboldt) can synthesize folate de novo via the folate biosynthesis pathway involving folA, folC, folE, folKP, and ptpS genes.

Gender-affirming surgery (GAS) is among the most rapidly growing and expanding subfields in plastic surgery due to increased awareness, decreased stigma, rising demand, and improved access for transgender and gender non-conforming individuals (TGNC). In order to address potential barriers and facilitators in GAS education and training, there is a need to explore the experiences of TGNC individuals. The purpose of this study was to qualitatively explore the factors that influence TGNC patient experiences in surgical consultation for GAS.

Background: Young Black women between the ages of 18 and 24 years are disproportionately impacted by HIV, yet they have a low self-perception of HIV risk and limited exposure to prevention strategies. Pre-exposure prophylaxis (PrEP) is a safe and effective biomedical HIV prevention strategy for those at risk for HIV infection, but uptake has been slow among cisgender women. Family planning clinics are a primary source of health care access for young women, providing an ideal opportunity to integrate PrEP information and care into existing clinic practices.

: In the not-so-distant future, orthopaedic surgeons will be exposed to machines that begin to automatically "read" medical imaging studies using a technology called deep learning.

: Deep learning has demonstrated remarkable progress in the analysis of medical imaging across a range of modalities that are commonly used in orthopaedics, including radiographs, computed tomographic scans, and magnetic resonance imaging scans.

: There is a growing body of evidence showing clinical utility for deep learning in musculoskeletal radiography, as evidenced by studies that use deep learning to achieve an expert or near-expert level of performance for the identification and localization of fractures on radiographs.

Background: Patients with multiple sclerosis (MS) experience disease flares that can be precipitated by the presence of infection. Discerning asymptomatic bacteriuria from urinary tract infection (UTI) in patients with MS is complicated by lower urinary tract dysfunction, leading to potentially inappropriate antimicrobial use. In this study the antimicrobial treatment practices for positive urine cultures in patients with MS were evaluated.

The purported goals of commercial sex work criminalization policies in the United States have shifted over the past two decades as local jurisdictions have adopted End Demand reforms. These reforms aim to refocus arrest from individuals who sell sexual services to buyers and facilitators, representing a departure from the quality-of-life, nuisance-focused approach of the late twentieth century. This article presents a case study examining enforcement of commercial sex laws in Chicago, a city that has been heralded as a leader in End Demand reforms.
