Long-Term Risk of Acute Myocardial Infarction in Patients With a Transient Ischemic Attack: A Danish Nationwide Cohort Study.

Background: Sparse information regarding the long-term risk of acute myocardial infarction (MI) following a transient ischemic attack (TIA) emphasizes further research to guide preventive strategies and risk stratification in patients with a TIA.

Methods: We conducted a nationwide cohort study to investigate the 5-year risk of MI and all-cause mortality in patients with a first-time TIA. Patients with a first-time TIA were identified in the Danish Stroke Registry (2013-2020), matched on age, sex, and calendar year (1:4) with the general population and (1:1) with patients with first-time ischemic stroke.

Effects of repeated intra-silicone oil injections of methotrexate on proliferative vitreoretinopathy grade C: a multicenter randomized controlled trial.

In this randomized controlled trial, we assessed the effects of three consecutive intra-silicone oil (SO) injections of methotrexate (MTX) on the outcomes of surgery for proliferative vitreoretinopathy grade C (PVR-C). Seventy-four eyes of 74 patients with PVR-C were included. Of these, 37 eyes were assigned to the MTX group and 37 eyes to the control group.

Routine intercostal artery reattachment strategy reduces delayed and permanent spinal cord injury after open descending thoracic and thoracoabdominal aortic aneurysm repair.

Objective: During open descending thoracic and thoracoabdominal aortic aneurysm (DTAA/TAAA) repair, we used a routine T8-T12 intercostal artery (ICA) reattachment strategy from July 2004 to June 2009 and after 2017, we used a selective ICA reattachment strategy (reattaching T8-T12 ICAs only when neuromonitor signals were lost) from July 2009 to 2016. This study reviewed our nearly 2-decade experience to assess the impact of 2 ICA reattachment strategies on spinal cord injury (SCI).

Methods: All open DTAA/TAAA repairs performed from July 2004 to June 2022 were included, except for cases without intraoperative cerebral spinal fluid drainage.

Open Thoracoabdominal Aortic Aneurysm Repair.

Operative techniques and perioperative management for thoracoabdominal aortic aneurysm (TAAA) have been modified and refined, but the morbidity and mortality remain high. Major challenges in open TAAA repair are prevention of ischemic insults to multiple organs, especially the spinal cord, and minimizing bleeding. The purpose of this narrative review is to provide currently available techniques and management strategies for open TAAA repair that optimize outcomes.

Effectiveness and impact of monovalent rotavirus vaccination in Afghanistan: a test-negative case-control analysis.

Background: Afghanistan introduced monovalent rotavirus vaccine (Rotarix) into its national immunisation schedule in January, 2018. While post-licensure studies have shown substantial declines in rotavirus gastroenteritis cases and deaths globally, there is little evidence of rotavirus vaccine effectiveness and impact from low-income countries in Asia. We aimed to evaluate the effectiveness of the Rotarix vaccine and the impact of Rotarix vaccine on rotavirus gastroenteritis hospitalisations (ie, hospital admissions) among children younger than 5 years in Afghanistan.

Open Treatments for Thoracoabdominal Aortic Aneurysm Repair.

Thoracoabdominal aortic aneurysms (TAAA) represent a unique pathology that is associated with considerable mortality if untreated. While the advent of endovascular technologies has introduced new modalities for consideration, the mainstay of TAAA treatment remains open surgical repair. However, the optimal conduct of open TAAA repair requires careful consideration of patient risk factors and a collaborative team effort to mitigate the risk of perioperative complications.

Hybrid Genetic Algorithm for Clustering IC Topographies of EEGs.

Clustering of independent component (IC) topographies of Electroencephalograms (EEG) is an effective way to find brain-generated IC processes associated with a population of interest, particularly for those cases where event-related potential features are not available. This paper proposes a novel algorithm for the clustering of these IC topographies and compares its results with the most currently used clustering algorithms. In this study, 32-electrode EEG signals were recorded at a sampling rate of 500 Hz for 48 participants.

Cooling times were divided into quartiles and clinical outcome event rates were compared across quartiles using contingency table methods.

Origin and Dynamics of Mycobacterium tuberculosis Subpopulations That Predictably Generate Drug Tolerance and Resistance.

Initial responses to tuberculosis treatment are poor predictors of final therapeutic outcomes in drug-susceptible disease, suggesting that treatment success depends on features that are hidden within a small minority of the overall infecting Mycobacterium tuberculosis population. We developed a multitranswell robotic system to perform numerous parallel cultures of genetically barcoded M. tuberculosis exposed to steady-state concentrations of rifampicin to uncover these difficult-to-eliminate minority populations.
