Background: The prior trials investigating triple-H therapy for preventing delayed cerebral ischemia (DCI) enrolled patients with aneurysmal subarachnoid hemorrhage (aSAH) who underwent early aneurysm therapy within 3 days. However, surgical clipping might be performed during 4-7 days that high incidence cerebral vasospasm is likely. We examined effects of hypervolemia-augmented blood pressure (HV-ABP) protocol on DCI prevention when clipping was delayed.

Objective: A scoring system for aneurysmal subarachnoid hemorrhage (aSAH) is useful for guiding treatment decisions, especially in urgent-care limited settings. This study developed a simple algorithm of clinical conditions and grading to predict outcomes in patients treated by clipping or coiling.

Methods: Data on patients with aSAH hospitalized in a university's neurovascular center in Thailand from 2013 to 2018 were obtained for chart review.

Background: For patients with aneurysmal subarachnoid hemorrhage (aSAH), the Universal Coverage Scheme in Thailand covers the full costs of surgical and endovascular procedures except for those of embolization coils and assisting devices. Costs and effectiveness were compared between endovascular coiling and neurosurgical clipping to inform reimbursement policy decisions.

Methods: Costs and quality-adjusted life years (QALYs) were compared between coiling and clipping using the decision tree and Markov models.

Objective: Shunt failure is common among patients undergoing ventriculoperitoneal shunting for treatment of hydrocephalus. The present study examined long-term shunt failure and associated risk factors in pediatric patients by using a national hospitalization database of Thailand.

Methods: Patients 17 years or younger who had been admitted to 71 public hospitals in 2012-2017 for first-time ventriculoperitoneal shunting for diseases with known etiology and discharged alive were followed through 2019 to ascertain shunt failure.

Introduction: Craniofacial trauma may potentially have significant blood loss which may lead to death in some trauma patients.

Case Report: We report a case of a 43-year-old male who had a lethal noncompressible arterial hemorrhage from a penetrating wound on his left frontotemporal and preauricular region. Extensive bleeding was successfully temporarily controlled by external carotid artery (ECA) occlusion.

Background: Evidence on access to reperfusion therapy for patients with ST-segment elevation myocardial infarction (STEMI) and associated mortality in developing countries is scarce. This study determined time trends in the nationally aggregated reperfusion and mortality, examined distribution of percutaneous coronary intervention (PCI) utilization across provinces, and assessed the reperfusion-mortality association in Thailand that achieved universal health coverage in 2002.

Methods: Data on hospitalization with STEMI in 2011-2017 of 69,031 Universal Coverage Scheme (UCS) beneficiaries were used for estimating changes in the national aggregates of % reperfusion and mortality by a time-series analysis.

Background: Cholinesterase inhibitors (ChEIs) and memantine have been reported to provide modest benefits for cognition and aspects of functioning in Alzheimer's disease (AD). Ginkgo biloba extract (EGb761), a phytomedicine, is widely used and expected to be well-tolerated. A few trials have compared EGb761 with ChEIs, and the results were inconclusive.

Objective: The objective of this study was to assess the cost effectiveness of direct-acting oral anticoagulants for stroke prevention in Thai patients with non-valvular atrial fibrillation and a HAS-BLED score of 3.

Methods: Total costs (US$) in 2017 and quality-adjusted life-years were estimated over 20 years using a Markov model. A base-case analysis was conducted under a societal perspective, which included direct healthcare, non-healthcare and indirect costs in Thailand.
