Purpose: The purpose of this study was to investigate the use of anterior segment imaging in diagnosing Kayser-Fleischer rings in patients with Wilson disease.
Methods: In a tertiary center for Wilson disease, patients were examined with a Pentacam HR Scheimpflug-based tomography device in addition to conventional slit-lamp examination. The inferior part of the cornea was analyzed using both a built-in densitometry module and ImageJ.
Results: Thirty-one patients with Wilson disease (78% of all Danish patients) were included, resulting in 83 examinations over a 5-year period. Ten had a manifest Kayser-Fleischer ring in the inferior part of the cornea on at least 1 examination, 5 had other causes of peripheral corneal scatter, and 16 had normal examinations. The built-in densitometry module performed poorly in discriminating between the presence and absence of a Kayser-Fleischer ring. However, analysis of the images in ImageJ and calculation of a normalized signal (peak posterior value/peak anterior value) with a cutoff value set to 1 detected 28 of 31 Kayser-Fleischer rings and resulted in 96% sensitivity and 95% specificity. In 12 patients who underwent 3 or more examinations during the period, changes in the normalized signal seemed to reflect the efficiency of the treatment, although more studies are needed for this conclusion.
Conclusions: ImageJ-based analysis of Pentacam images has a high sensitivity in detecting Kayser-Fleischer rings and can be used as a diagnostic procedure for Wilson disease and may be a tool to monitor the disease in an objective manner.

Polycystic kidney diseases (PKD) are genetic disorders which disrupt kidney architecture and function. Autosomal recessive PKD (ARPKD) is a rare form of PKD, caused by mutations in PKHD1, and clinically more severe than the more common autosomal dominant PKD (ADPKD). Prior studies have implicated Hedgehog (Hh) signaling in ADPKD, with increased levels of Hh components in experimental ADPKD and reduced cystogenesis following pharmacological Hh inhibition.

The purpose of this study was to evaluate clinical outcomes after primary shoulder arthroplasty in patients with a history of nonarthroplasty shoulder surgery, and whether certain modifiable risk factors (MRFs) were negatively associated with final outcome measures. The secondary purpose was to determine if costs or complications were higher in patients with prior shoulder surgery.

Background: We investigated hospitalized carbapenem-resistant Enterobacterales (CRE) and extended-spectrum β-lactamase-producing Enterobacterales (ESBL-E) cases with and without COVID-19, as identified through Emerging Infections Program surveillance in 10 sites from 2020 to 2022.
Methods: We defined a CRE case as the first isolation of , complex, , , , or resistant to any carbapenem. We defined an ESBL-E case as the first isolation of , , or resistant to any third-generation cephalosporin and nonresistant to all carbapenems tested.

Background: Individuals with co-occurring posttraumatic stress disorder (PTSD) and HIV are at high-risk for negative HIV-related outcomes, including low adherence to antiretroviral therapy, faster disease progression, more hospitalizations, and almost twice the rate of death. Despite high rates of PTSD in persons with HIV (PWH) and poor HIV-related health outcomes associated with PTSD, an effective evidence-based treatment for PTSD symptoms in PWH does not exist.
Objective: This study aimed to describe the adaptation and theater testing of an evidence-based intervention designed for people with co-occurring PTSD and HIV.
