Residual Mitral Regurgitation Interacts With Transmitral Mean Pressure Gradient to Modify the Association With Mortality Following Transcatheter Edge-to-Edge Repair.

Background: The association, if any, between the transmitral mean pressure gradient (TMPG) after mitral transcatheter edge-to-edge repair and 1-year mortality is controversial in patients undergoing mitral transcatheter edge-to-edge repair with the MitraClip system. We sought to estimate the association between intraoperatively measured residual mitral regurgitation (rMR) and TMPG and 1-year mortality among patients undergoing mitral transcatheter edge-to-edge repair to facilitate decisions on additional devices.

Methods: In patients with severe secondary (functional) MR, we analyzed registry data using generalized estimating equations.

PET Quantification in Healthy Humans of Cyclooxygenase-2, a Potential Biomarker of Neuroinflammation.

Cyclooxygenase-2 (COX-2) is present in a healthy brain at low densities but can be markedly upregulated by excitatory input and by inflammogens. This study evaluated the sensitivity of the PET radioligand [C]-6-methoxy-2-(4-(methylsulfonyl)phenyl)--(thiophen-2-ylmethyl)pyrimidin-4-amine ([C]MC1) to detect COX-2 density in a healthy human brain. The specificity of [C]MC1 was confirmed using lipopolysaccharide-injected rats and transgenic mice expressing the human gene, with 120-min baseline and blocked scans using COX-1 and COX-2 selective agents.

Myosin-based nucleation of actin filaments contributes to stereocilia development critical for hearing.

Assembly of actin-based stereocilia is critical for cochlear hair cells to detect sound. To tune their mechanosensivity, stereocilia form bundles composed of graded rows of ascending height, necessitating the precise control of actin polymerization. Myosin 15 (MYO15A) drives hair bundle development by delivering critical proteins to growing stereocilia that regulate actin polymerization via an unknown mechanism.

Adjuvant Cytotoxic Chemotherapy may not be Associated with a Survival Advantage for Resected Intrahepatic Cholangiocarcinoma.

Background: Randomized data suggest improved survival with adjuvant chemotherapy for biliary tract cancers; however, subset analyses of intrahepatic cholangiocarcinoma (IHC) show limited survival benefit. This study evaluated the impact of adjuvant chemotherapy on recurrence patterns and overall survival (OS) in patients with resected IHC.

Methods: Patients who underwent curative-intent resection for IHC were identified within a bi-institutional dataset and the National Cancer Database (NCDB).

Mice develop obesity and lose myocardial metabolic flexibility months after exertional heat stroke.

As global temperatures rise, heat-related chronic health disorders are predicted to become more prevalent. We tested whether a single exposure to acute heat illness, using a preclinical mouse model of exertional heat stroke (EHS), can induce late-emerging health disorders that progress into chronic disease. Following EHS, mice were followed for 3 months; after two weeks of recovery, half were placed on a Western diet to determine if previous EHS exposure amplifies the negative consequences of an atherogenic diet.

Change in management for digital subtraction angiography-identified false-positive traumatic vertebral artery injury.

Background: For patients with suspected traumatic vertebral artery injury (TVAI), CT angiography (CTA) is the first-line screening modality. Digital subtraction angiography (DSA) serves as the confirmatory diagnostic imaging, and is the gold standard for cerebrovascular injury assessment, due to its higher sensitivity and specificity. Among patients with TVAI based on CTA who have undergone follow-up DSA, this study aims to investigate how diagnostic information with additional imaging affects clinical management.

Leveraging Metal Complexes for Microsecond Lifetime-Based Chloride Sensing.

Chloride is the most abundant anion in cells and plays many critical roles in maintaining cellular homeostasis. However, current chloride indicators are rare with inherent sensitivity in their emission properties, such as vulnerability to pH changes or short emission lifetimes. These limitations restrict their application in aqueous media and imaging.
