Changes of marine environments due to human activities in coastal waters of Korea.

A comprehensive review of scholarly articles was conducted to examine the marine environmental changes in four representative bays in Korea. Cheonsu Bay experienced a reduction in water area to half of its original size due to the completion of dikes and related reclamation projects. Consequently, the flow environment and biota were altered, leading to increased organic pollution.

Factors controlling the origin of Cochlodinium polykrikoides blooms along the Goheung coast, South Korea.

We investigated the factors influencing the origin of Cochlodinium polykrikoides blooms along the Goheung coast (GH), and compared them to those along the Geoje (GJ) coast and in the East China Sea (ECS) which were used as reference sites. Stratification did not develop in GH during C. polykrikoides blooms, unlike that in GJ.

ComparisOn of neointimal coVerage betwEen zotaRolimus-eluting stent and everolimus-eluting stent using Optical Coherence Tomography (COVER OCT).

Background: Data on strut surface coverage of second-generation drug-eluting stents (DES) are limited. We investigated stent strut coverage of resolute zotarolimus-eluting stent (ZES-R) or everolimus-eluting stent (EES) at 9 months after implantation using optical coherence tomography (OCT).

Methods: ComparisOn of neointimal coVerage betwEen zotaRolimus-eluting stent and everolimus-eluting stent using Optical Coherence Tomography (COVER OCT) is a prospective, randomized, multicenter trial comparing ZES-R to EES using OCT at 9 months after stent implantation.

Amniotic fluid embolism that took place during an emergent Cesarean section -A case report-.

Amniotic fluid embolism (AFE) is a rare but fatal obstetric emergency, characterized by sudden cardiovascular collapse, dyspnea or respiratory arrest and altered mentality, disseminated intravascular coagulation (DIC). It can lead to severe maternal morbidity and mortality, but the prediction of its occurrence and treatment are very difficult. We experienced a case of AFE during emergent Cesarean section in a 40(+6) weeks healthy pregnant woman, age 33.

The relationship between symphysis-fundal height and intravenous ephedrine dose in spinal anesthesia for elective cesarean section.

Background: A decreased lumbosacral subarachnoidal space volume is a major factor in the cephalad intrathecal spread of local anesthetics in term parturients and their subarachnoidal space is decreased due to the compressive effect of huge uteri. Therefore, they show a higher level of sensory block and hypotensive episodes. The purpose of this study is to investigate whether the symphysis-fundal height (SFH) correlates with the highest sensory level and the amount of ephedrine administered under spinal anesthesia.

Comparison of sirolimus-eluting stent and paclitaxel-eluting stent for long-term cardiac adverse events in diabetic patients: the Korean Multicenter Angioplasty Team (KOMATE) Registry.

Background: There is some controversy on long-term cardiac outcomes between sirolimus-eluting stents (SES) and paclitaxel-eluting stents (PES) in diabetes mellitus (DM). We compared cardiac adverse events after SES and PES implantation in patients with DM over a period of 3 year.

Methods: A total of 634 patients with DM treated with SES (n = 428) or PES (n = 206) were consecutively enrolled in the KOMATE registry from 2003 to 2004.
