Korean Circulation Journal 2025;55(2):151-160
Background and Objectives:
The timing of the reinstitution of warfarin after cesarean section (CS) delivery was not adequately addressed in the literature. This study aims to evaluate the risks of early versus late initiation of warfarin post-CS in patients with mechanical heart valves.
Methods:
This randomized, open-label cohort study included 114 pregnant women with mechanical heart valves planned to be delivered by CS at or after 28 weeks of gestation.Patients were randomly divided into two groups: Day-2-group, where warfarin was started on day 2, and Day-5-group, where warfarin was started on day 5 after CS. Maternal postoperative bleeding complications, mechanical valve thrombosis, need for blood transfusion or reoperation, and maternal mortality were identified.
Results:
Ten women (8.8%) had 11 bleeding complications, of whom 2 patients (20%) had intraperitoneal hemorrhage (none in Day-2-group and 2 in Day-5-group), 3 patients (30%) had subcutaneous hematoma (none in Day-2-group and 3 in Day-5-group), and 6 patients (60%) had sub-rectus hematoma (3 in Day-2-group and 3 in Day-5-group). No mechanical valve thrombosis, other thromboembolic events, or in-hospital maternal mortality were reported.
Conclusion
Despite the small number of events, the bleeding risk was lower in the group with early post-CS warfarin introduction than in the group with late warfarin introduction in patients with prosthetic heart valves.

Clinical case studies and reporting are important to the discovery of new disorders and the advancement of medical sciences. Both clinicians and basic scientists play equally important roles leading to treatment discoveries for both cures and symptoms. In the field of movement disorders, exceptional observation of patients from clinicians is imperative, not just for phenomenology but also for the variable occurrences of these disorders, along with other signs and symptoms, throughout the day and the disease course. The Movement Disorders in Asia Task Force (TF) was formed to help enhance and promote collaboration and research on movement disorders within the region. As a start, the TF has reviewed the original studies of the movement disorders that were preliminarily described in the region. These include nine disorders that were first described in Asia: Segawa disease, PARK-Parkin, X-linked dystonia-parkinsonism, dentatorubral-pallidoluysian atrophy, Woodhouse-Sakati syndrome, benign adult familial myoclonic epilepsy, Kufor-Rakeb disease, tremulous dystonia associated with mutation of the calmodulin-binding transcription activator 2 gene, and paroxysmal kinesigenic dyskinesia. We hope that the information provided will honor the original researchers and help us learn and understand how earlier neurologists and basic scientists together discovered new disorders and made advances in the field, which impact us all to this day.

Journal of Stroke 2023;25(2):282-290
Background:
and Purpose Randomized trials proved the benefits of mechanical thrombectomy (MT) for select patients with large vessel occlusion (LVO) within 24 hours of last-known-well (LKW). Recent data suggest that LVO patients may benefit from MT beyond 24 hours. This study reports the safety and outcomes of MT beyond 24 hours of LKW compared to standard medical therapy (SMT).
Methods:
This is a retrospective analysis of LVO patients presented to 11 comprehensive stroke centers in the United States beyond 24 hours from LKW between January 2015 and December 2021. We assessed 90-day outcomes using the modified Rankin Scale (mRS).
Results:
Of 334 patients presented with LVO beyond 24 hours, 64% received MT and 36% received SMT only. Patients who received MT were older (67±15 vs. 64±15 years, P=0.047) and had a higher baseline National Institutes of Health Stroke Scale (NIHSS; 16±7 vs.10±9, P<0.001). Successful recanalization (modified thrombolysis in cerebral infarction score 2b-3) was achieved in 83%, and 5.6% had symptomatic intracranial hemorrhage compared to 2.5% in the SMT group (P=0.19). MT was associated with mRS 0–2 at 90 days (adjusted odds ratio [aOR] 5.73, P=0.026), less mortality (34% vs. 63%, P<0.001), and better discharge NIHSS (P<0.001) compared to SMT in patients with baseline NIHSS ≥6. This treatment benefit remained after matching both groups. Age (aOR 0.94, P<0.001), baseline NIHSS (aOR 0.91, P=0.017), Alberta Stroke Program Early Computed Tomography (ASPECTS) score ≥8 (aOR 3.06, P=0.041), and collaterals scores (aOR 1.41, P=0.027) were associated with 90-day functional independence.
Conclusion
In patients with salvageable brain tissue, MT for LVO beyond 24 hours appears to improve outcomes compared to SMT, especially in patients with severe strokes. Patients’ age, ASPECTS, collaterals, and baseline NIHSS score should be considered before discounting MT merely based on LKW.

Introduction: To combat the COVID-19 pandemic, Malaysia started vaccination of front-liners and adults in the community. The latter group might have insufficient knowledge to accept COVID-19 vaccination, therefore this research
was to assess the knowledge and acceptance of COVID-19 vaccination among youths, specifically students in a
Malaysian college. Methods: A cross-sectional study was conducted among 481 foundation students in Kolej MARA
Kulim (KMKU). The minimum sample size, using Epi Info was 214. Students answered an online questionnaire using
google form which included demographic data (age, gender) and ten questions on knowledge and acceptance of
COVID-19 vaccination. For knowledge questions, students answered “yes”, “no” or “don’t know”, correct answer
scoring 1. For acceptance questions, a 5-point Likert scale was used ranging from “strongly disagree” to “strongly
agree”. EXCEL and SPSS version 23 were used for analysis with Chi-square test done to test association (significant for
p-value <0.05). Results: The response rate was 65.1% with 313 students, (45.4% males, and 54.6% females) aged
18-19 years. The majority (83.7%) had satisfactory to excellent knowledge scores (mean = 6.66 (SD=2.299, 95%
CI 6.40-6.91), median = 7 (± IQR =3), while 16.3% obtained poor scores (≤ 4). The majority (90%) accepted vaccination. Higher knowledge scores were associated with higher acceptance rates in both genders (p-value= 0.000).
Significantly more females (90.6%) than males (80.3%) had positive attitude towards vaccination (p-value = 0.009).
Conclusions: The majority of the foundation students in KMKU were knowledgeable on COVID-19 vaccination and
willing to receive the vaccination against the novel coronavirus.

CD88, which stands for "Cluster of Differentiation 88," is also known as C5aR, which stands for "Complement 5a receptor." This complement receptor has 7 transmembrane domains and is found on various cell types, including monocytes, macrophages, dendritic cells, epithelial cells, adipocytes, and endothelial cells. Atherosclerosis is a condition associated with chronic inflammation of the arterial walls. It's marked by lipid retention and building, monocyte and T lymphocyte recruitment into the intima, foam cell generation, smooth muscle cell proliferation, and collagen and protein accumulation. C5a has been found in a wide range of atherosclerotic lesions, from fatty streaks to advanced plaques. The expression of CD88 has been linked to both proatherogenic and antiatherogenic effects in atherosclerosis. Initial activities of C5a in atherosclerosis include chemotaxis, oxidative burst, and vascular adhesion molecule activation. CD88 expression has also been linked to the formation of atherosclerosis plaques via adaptive immune cell activation. Regulation and effector functions require ligand-receptor binding (C5a-C5aR) in the pathogenesis of atherosclerosis. CD88 expression has been linked to all stages of atherosclerosis. Myeloid cells have been identified to express CD88, which is responsible for many of C5a's biological properties. During atherogenesis, macrophages and dendritic cells are two important antigen presentation cells (APCs) that carry and display the CD88 surface marker. The proliferation and division of CD4+ T helper cells are controlled by macrophages, dendritic cells, and mast cells, which are also responsible for the release of both proatherogenic and antiatherogenic cytokines. However, there is no evidence that naive CD4+ T helper cells express CD88 from any of the research that has been done. Since CD88 is expressed by a wide variety of immune cells in atherosclerotic plaques, including macrophages, dendritic cells, T lymphocytes, and B lymphocytes, this review will focus on the influence of CD88 expressing immune cells in atherosclerosis formation.

Annals of Rehabilitation Medicine 2021;45(4):284-293
Objective:
To investigate the combined effect of extracorporeal shockwave therapy (ESWT) and integrated neuromuscular inhibition (INI) on myofascial trigger points in the upper trapezius.
Methods:
Sixty subjects aged 18–24 years old with active myofascial trigger points in the upper trapezius were studied. Participants were assigned randomly to either group A who received ESWT one session/week, group B who received INI three sessions/week, or group C who received ESWT in addition to INI. All groups completed 4 weeks of intervention. The following main outcome measures were evaluated at baseline and after 4 weeks of intervention: pain intensity, functional disability, pressure pain threshold (PPT), sympathetic skin response (SSR), and neuromuscular junction response (NMJR).
Results:
Within-group analysis revealed a significant decline in visual analog scale (VAS), Arabic neck disability index (ANDI), and NMJR and incline in PPT and SSR latency post-intervention (p<0.001). Multiple comparison analysis showed a substantial difference between the groups, while the major changes favored group C (p<0.05).
Conclusion
Combined treatment with ESWT and INI for treating myofascial trigger points in the upper trapezius is more effective than using only one of the two approaches in terms of clinical, functional, and neurophysiological aspects.
