Traumatic subarachnoid hemorrhage (T-SAH) is said to be typically occurred in a young, healthy, but intoxicated man who receives a minor blow, immediately collapses, and dies within minutes. Sixteen forensic cases of T-SAH were analysed in the point of time of collapse, blood alcohol level, injured site, vascular rupture sites, and sentenced servitude. Majority of the cases (12 cases) were autopsied in the department of Kyungpook National University. Two cases of National Institute of Scientific Investigation, South District Office and 1 case of Jeju National University were added. Autopsy was not done in one case. There were 14 male and 2 female victims. The peak age were their forties (7 cases) and under twenties (7 cases). The time of incident was most often at night. The survival time from the time of trauma until death indicates that 62.5% (10 victims) died immediately from the assault, 12.5% (2 victims) died within 30 minutes. Blood alcohol was detected in 11 cases (68.8%), and mean blood alcohol level was 0.16% (0.08-0.22%). The damage was generated to the facial region, especially around the jaw and below the ears (7 cases), and temporal areas (4 cases). Bleeding foci were detected in 7 cases; basilar artery (2 cases), left vertebral artery (2 cases), and right vertebral artery (3 cases). Meticulous autopsy techniques for identifying the vascular rupture sites are required. The author conclude that tremendous emphasis must be placed on the fact that fatal T-SAH can occur due to minor facial trauma and social campaign for alerting people to the danger of T-SAH is needed.

Purpose:
Only a few Asian studies have discussed the impact of statin intensity on clinical outcomes in patients with peripheral artery disease (PAD). We aimed to investigate the clinical impact of statin intensity in patients with PAD after endovascular revascularization.
Materials and Methods:
From April 2009 to June 2019, 376 patients with lower extremity PAD treated with endovascular revascularization were enrolled. They were classified into three groups according to statin intensity: no-statin, low-to-moderate intensity (LMI), and high-intensity (HI). The primary outcomes were major adverse cardiovascular events (MACE) and major adverse limb events (MALE).
Results:
During the 40-month follow-up, MACE occurred less frequently in the HI and LMI groups than the no-statin group (11.4% vs. 16.0% vs. 39%, p<0.001). In adjusted Cox models, the HI group had the fewest MACE [hazard ratio (HR): 0.447; 95% confidence interval (CI): 0.244–0.834; p=0.018] and MALE (HR: 0.360; 95% CI: 0.129–1.006; p=0.051) events, while the LMI group had fewer MACE (HR: 0.571; 95% CI: 0.326–1.0; p=0.050) events than the no-statin group. HI statin therapy was associated with better outcomes in terms of MALE (HR: 0.432; 95% CI: 0.223–0.837; p=0.003) than LMI statin therapy after inverse probability treatment weighting analysis.
Conclusion
HI and LMI statin use is associated with a significant reduction in MACE events than no-statin use. HI statin use was associated with better MALE outcomes than no-statin or LMI statin use.

Background:
Although regular physical activity benefits cardiovascular health, there is a concern that intense exer‑ cise is linked to the promotion of atrial fibrillation (AF) and coronary plaque rupture. However, the impact of physical activity on the outcomes of patients with concomitant AF and coronary artery disease (CAD) remains unclear. This study aimed to evaluate the association with clinical outcomes according to the level of physical activity in patients with concomitant AF and CAD.
Methods:
We assessed 551 patients with AF and CAD (mean age, 67.1 ± 9.8 years) who completed a self-reported questionnaire for physical activity from 2015 to 2020 in a single tertiary-care hospital. Physical activity levels were con‑ verted into metabolic equivalent of task (MET) per week and categorized to correspond with multiple public health recommendations. We examined the association between physical activity, all-cause mortality, and major adverse cardiac and cerebrovascular events (MACCE).
Results:
The risks of all-cause mortality (P for linear trend = 0.017) and MACCE (P for linear trend = 0.05) appeared inverse trend with a greater level of physical activity. Compared with inactive patients, patients who met the recom‑ mended target range of physical activity (500–1,000 MET-min/week: unadjusted hazard ratio [HR] = 0.58, 95% confi‑ dence interval [CI] = 0.36–0.99) and highly active patients who exceeded the minimum recommended level (≥ 1,000 MET-min/week: unadjusted HR = 0.47, 95% CI = 0.25–0.88) had a lower risk of all-cause mortality in the unadjusted model; however, these associations did not remain significant after adjusting for the model. There was no evidence of increased risk of all-cause mortality and MACCE at levels of physical activity above the recommended target range, even with vigorous-intensity physical activity exceeding the recommended target range.
Conclusions
There appears to be an inverse trend between physical activity levels and all-cause mortality and MACCE in patients with concomitant AF and CAD. No excess risk of mortality or MACCE was found at exercise levels above the recommended target range. Further large-scale studies are warranted to create an improved evidence base concerning the effects of physical activity in patients with AF and CAD.
