Objective: Herein we investigate whether transportation by doctor helicopter (DH) affects blood pressure (BP) in stroke patients.

Methods: A total of 119 stroke patients treated by the DH between April 2015 and March 2019 were analyzed. The average BP before and after admission to the DH was compared for all stroke patients. The average BP before and after in the infarct group (cerebral infarction/transient ischemic attack) and the bleeding group (cerebral hemorrhage/subarachnoid hemorrhage) was compared. The average BP before and after in Glasgow Coma Scale (GCS) mild, moderate, and severe groups was also compared. Statistical analysis was performed using a paired t-test.

Results: The average BP of stroke patients increased after admission to the DH (before = 156.8 mm Hg and after = 165.0 mm Hg, P < .01). Both the infarct group and the bleeding group had elevated BP after admission (infarct group: before = 151.2 mm Hg and after = 157.8 mm Hg, P = .02; bleeding group: before = 167.5 mm Hg and after = 178.5 mm Hg, P = .04). The BP after admission was elevated only in the mild GCS group.

Conclusion: When transporting conscious stroke patients by the DH, it is necessary to keep in mind that BP may elevate.

Background: The systemic immune-inflammation index (SII) is an emerging marker of inflammation, and the onset of psoriasis is associated with inflammation. The aim of our study was to investigate the potential impact of SII on the incidence rate of adult psoriasis.

Methods: We conducted a cross-sectional study based on the National Health and Nutrition Examination Survey (NHANES) 2011-2014 data sets.

Background: Construct validity and responsiveness of upper limb outcome measures are essential to interpret motor recovery poststroke. Evaluating the associations between clinical upper limb measures and sensor-based arm use (AU) fosters a coherent understanding of motor recovery. Defining sensor-based AU metrics for intentional upper limb movements could be crucial in mitigating bias from walking-related activities.

Background: Proton pump inhibitors (PPIs) are commonly used for managing gastroesophageal disorders but concerns about their potential association with increased stroke risk have emerged, especially among patients with pre-existing cardiovascular conditions such as acute coronary syndrome (ACS). This systematic review and meta-analysis aim to assess the risk of stroke associated with PPI use, stratified by the presence or absence of pre-existing CVD.

Methods: This review was conducted following the PRISMA guidelines and included studies up to March 2024 from PubMed, Embase, and Web of Science.

Purpose: Posterior fossa ring-enhancing lesions (PFREL) in the adult immunocompetent hosts pose a diagnostic challenge. We aimed to evaluate the spectrum of PFREL etiologies and propose a diagnostic algorithm.

Methods: This study involved a retrospective analysis of PFREL cases from our institution (January 2023 to April 2024) and a systematic literature review conducted using Embase and PubMed databases following the PRISMA 2020 guidelines.
