Background and Objectives:
This study aimed to investigate the association between cardiovascular events and 2 different levels of elevated on-treatment diastolic blood pressures (DBP) in the presence of achieved systolic blood pressure targets (SBP).
Methods:
A nation-wide population-based cohort study comprised 237,592 patients with hypertension treated. The primary endpoint was a composite of cardiovascular death, myocardial infarction, and stroke. Elevated DBP was defined according to the Seventh Report of Joint National Committee (JNC7; SBP <140 mmHg, DBP ≥90 mmHg) or to the 2017 American College of Cardiology/American Heart Association (ACC/AHA) definitions (SBP <130 mmHg, DBP ≥80 mmHg).
Results:
During a median follow-up of 9 years, elevated on-treatment DBP by the JNC7 definition was associated with an increased risk of the occurrence of primary endpoint compared with achieved both SBP and DBP (adjusted hazard ratio [aHR], 1.14; 95% confidence interval [CI], 1.05–1.24) but not in those by the 2017 ACC/AHA definition. Elevated ontreatment DBP by the JNC7 definition was associated with a higher risk of cardiovascular mortality (aHR, 1.42; 95% CI, 1.18–1.70) and stroke (aHR, 1.19; 95% CI, 1.08–1.30). Elevated on-treatment DBP by the 2017 ACC/AHA definition was only associated with stroke (aHR, 1.10;95% CI, 1.04–1.16). Similar results were seen in the propensity-score-matched cohort.
Conclusion
Elevated on-treatment DBP by the JNC7 definition was associated a high risk of major cardiovascular events, while elevated DBP by the 2017 ACC/AHA definition was only associated with a higher risk of stroke. The result of study can provide evidence of DBP targets in subjects who achieved SBP targets.

Background:
s: The severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) has spread worldwide. Cardiac injury after SARS-CoV-2 infection is a major concern. The present study investigated impact of the biomarkers indicating cardiac injury in coronavirus disease 2019 (COVID-19) on patients' outcomes.
Methods:
This study enrolled patients who were confirmed to have COVID-19 and admitted at a tertiary university referral hospital between February 19, 2020 and March 15, 2020. Cardiac injury was defined as an abnormality in one of the following result markers: 1) myocardial damage marker (creatine kinase-MB or troponin-I), 2) heart failure marker (N-terminal-pro B-type natriuretic peptide), and 3) electrical abnormality marker (electrocardiography). The relationship between each cardiac injury marker and mortality was evaluated. Survival analysis of mortality according to the scoring by numbers of cardiac injury markers was also performed.
Results:
A total of 38 patients with COVID-19 were enrolled. Twenty-two patients (57.9%) had at least one of cardiac injury markers. The patients with cardiac injuries were older (69.6 ± 14.9 vs. 58.6 ± 13.9 years old, P = 0.026), and were more male (59.1% vs. 18.8%, P = 0.013).They showed lower initial oxygen saturation (92.8 vs. 97.1%, P = 0.002) and a trend toward higher mortality (27.3 vs. 6.3%, P = 0.099). The increased number of cardiac injury markers was significantly related to a higher incidence of in-hospital mortality which was also evidenced by Kaplan-Meier survival analysis (P = 0.008).
Conclusion
The increased number of cardiac injury markers is related to in-hospital mortality in patients with COVID-19.

BACKGROUND: This study evaluated the prevalence of osteosarcopenia, as well as the relationship between one-year mortality and osteosarcopenia, as defined by criteria of the Asian Working Group on Sarcopenia in patients age 60 or older with hip fracture. METHODS: A total of 324 patients age 60 years or older with hip fracture were enrolled in this retrospective observational study. The main outcome measure was the prevalence of osteosarcopenia, as well as the relationship between osteosarcopenia and 1-year mortality. The diagnosis of sarcopenia was carried out according to the Asian Working Group on Sarcopenia. Whole body densitometry analysis was used for skeletal muscle mass measurement and muscle strength were evaluated by handgrip testing. Mortality was assessed at the end of 1-year. Cox regression analysis was utilized to analyze the risk factor of osteosarcopenia. RESULTS: Of 324 patients with hip fracture, 93 (28.7%) were diagnosed with osteosarcopenia. In total, 9.0% died during the one-year follow-up. A one-year mortality of osteosarcopenia (15.1%) was higher than that of other groups (normal: 7.8%, osteoporosis only: 5.1%, sarcopenia only: 10.3%). Osteosarcopenia had a 1.8 times higher mortality rate than non-osteosarcopenia. CONCLUSION: The present study demonstrates that the prevalence of osteosarcopenia is not rare, and has a higher mortality rate than the non-osteosarcopenia group at the 1-year follow-up period. This is the first study evaluating the relationship between mortality and osteosarcopenia in patients with hip fracture.

Clinical outcomes of living donor liver transplantation (LDLT) for hepatocellular carcinoma (HCC) in patients with multiple myeloma (MM) have not been established in terms of HCC recurrence and MM deterioration after LDLT. A 51-year-old man with chronic hepatitis B was diagnosed with HCC and MM. Since the patient also had decompensated liver cirrhosis (LC), he underwent LDLT prior to autologous peripheral blood stem cell transplantation (PBSCT) to prevent fulminant hepatitis due to HBV reactivation. The patient received Epstein-Barr virus prophylaxis and a triple immunosuppressive regimen of tacrolimus, everolimus, and steroid after LDLT. Autologous PBSCT was performed 7 months after LDLT. He showed a complete response to treatment of MM without post-LT complications or HCC recurrence. In conclusion, LDLT could be adapted for treatment of MM patients with combined HCC and decompensated LC because it is an effective strategy of preventing HBV reactivation and HCC recurrence after induction therapy of MM.

PURPOSE: Response to preoperative transarterial chemoembolization (TACE) has been recommended as a biological selection criterion for liver transplantation (LT). The aim of our study was to identify optimal timing of living donor liver transplantation (LDLT) after TACE based on the TACE response. METHODS: We performed a retrospective study to assess recurrence in 128 hepatocellular carcinoma (HCC) patients who underwent LDLT following sequential TACE from January 2002 to March 2015 at a single institute. Cox proportional hazard models and Kaplan-Meier analysis were utilized to estimate HCC recurrence and find optimal timing for LDLT. RESULTS: Seventy-three and 61 patients were divided as the responder and nonresponder, respectively. Multivariate analysis showed independent pre-liver transplantation (pre-LT) predictors of recurrence were larger sized tumor (>3 cm, P = 0.024), nonresponse to TACE (P = 0.031), vascular invasion (P = 0.002), and extrahepatic nodal involvement (P = 0.001). In the 3-month time difference between last pre-LT TACE and LDLT subgroup, TACE responders showed significantly higher adjusted hazard ratio (aHR) of recurrence free survival (aHR, 6.284; P = 0.007), cancer specific survival (aHR, 7.033; P = 0.016), and overall survival (aHR, 7.055; P = 0.005). Moreover, for overall patients and responder groups, the significant time difference between last pre-LT TACE and LDLT was 2 months in the minimum P-value approach. CONCLUSION: In selected patients who showed good response to pre-LT TACE, a shorter time interval between TACE and LDLT may be associated with higher recurrence free survival, cancer specific survival, and overall survival.

Encapsulating peritoneal sclerosis (EPS) is a rare cause of intestinal obstruction by a thick fibrous membrane wrapping around the small intestine. It is a possible complication after liver transplantation (LT) that can be fatal. This report describes 2 cases of EPS after LT that were successfully treated with surgery, corticosteroids, tamoxifen, and mammalian target of rapamycin inhibitor. After treatment in both cases, the patients were able to start oral feeding and have been symptom free for more than 1 year. These cases suggests that for the management of EPS, surgical treatment is mandatory when the patients present with symptoms of intestinal obstruction or if there are findings suggestive of decreased mural perfusion. Surgery should be accompanied with medical treatment to prevent the relapse of EPS.

The Glissonian approach, due to its simplicity of procedure, is a technical procedure widely used in open hepatectomy. However, it is not easily applicable in the setting of the total laparoscopic approach because of movement restriction. We herein propose a new and simple method of performing hemihepatectomy by Glissonian approach called temporary inflow control of the Glissonian pedicle (TICGL) technique. Dissection of the Glisson pedicle from the liver parenchyma is done until the posterior margin of the pedicle is visualized, and is clamped with bulldog clamps. Encircling the pedicle is not necessary. Resection of the liver parenchyma is performed under inflow control of the resected side liver providing less bleeding. After sufficient resection is done so that the whole Glissonian pedicle structures are visualized, the pedicle is encircled, often very easily without the fear of bleeding from the posterior side of the pedicle, which is a common problem when encircling is done before parenchymal resection. The staplers may then be applied safely without injuring the major hepatic veins since they have been already exposed. Stapling is done while the tape is retracted toward the contralateral side. This retraction prevents injury or stricture of the contralateral Glissonian pedicle branch. The remnant liver parenchyma is resected and hepatectomy finalized. The TICGL technique provides a safe and easy way of performing major hemihepatectomies, not only by expert laparoscopic surgeons but by less experienced surgeons. It can therefore become a standard method of performing hemihepatectomy by Glissonian approach.

PURPOSE: This study was designed to assess the outcome of the extracorporeal membrane oxygenation (ECMO) in liver transplantation (LT) recipients with refractory septic shock and predict the prognosis of those cases. METHODS: From February 2005 to October 2012, ECMO was used in 8 cases of refractory septic shock. Laboratory values including lactate and total bilirubin level just before starting ECMO were obtained and sepsis-related organ failure assessment (SOFA) score, acute physiology and chronic health evaluation (APACH) II score and simplified acute physiology score (SAPS) 3 were calculated. Subsequent peak serum lactate and total bilirubin level, and SOFA score after 24 hours of starting ECMO were measured. RESULTS: Comparisons were made between survivors and nonsurvivors. ECMO was weaned off successfully in 3 patients (37.5%) and 2 patients (25%) survived to hospital discharge. Clinical scores including SOFA, APACH II, and SAPS3 and laboratory results including lactate, total bilirubin and CRP were not significantly different between survivor and nonsurvivor groups. Lactate level and SOFA score tended to decrease after ECMO support in survivor group and total bilirubin and CRP level tended to increase in nonsurvivor group. CONCLUSION: Our findings suggest that the implantation of ECMO might be considered in highly selected LT recipients with refractory septic shock.

Great advances have been made in the field of assisted reproductive technology (ART) since the first in vitro fertilization (IVF) baby was born in Korea in the year of 1985. However, it deserve to say that the invaluable data from fertility centers may serve as a useful source to find out which factors affect successful IVF outcome and to offer applicable information to infertile patients and fertility clinics. This article intended to report the status of ART in 2009 Korean Society of Obstetrics and Gynecology surveyed. The current survey was performed to assess the status and success rate of ART performed in Korea, between January 1 and December 31, 2009. Reporting forms had been sent out to IVF centers via e-mail, and collected by e-mail as well in 2012. With International Committee Monitoring Assisted Reproductive Technologies recommendation, intracytoplasmic sperm injection (ICSI) and non-ICSI cases have been categorized and also IVF-ET cases involving frozen embryo replacement have been surveyed separately. Seventy-four centers have reported the treatment cycles initiated in the year of 2009, and had performed a total of 27,947 cycles of ART treatments. Among a total of 27,947 treatment cycles, IVF and ICSI cases added up to 22,049 (78.9%), with 45.3% IVF without ICSI and 54.7% IVF with ICSI, respectively. Among the IVF and ICSI patients, patients confirmed to have achieved clinical pregnancy was 28.8% per cycle with oocyte retrieval, and 30.9% per cycle with embryo transfer. The most common number of embryos transferred in 2009 is three embryos (40.4%), followed by 2 embryos (28.4%) and a single embryo transferred (13.6%). Among IVF and ICSI cycles that resulted in multiple live births, twin pregnancy rate was 45.3% and triple pregnancy rate was 1.1%. A total of 191 cases of oocyte donation had been performed to result in 25.0% of live birth rate. Meanwhile, a total of 5,619 cases of frozen embryo replacement had been performed with 33.7% of clinical pregnancy rate per cycle with embryo transfer. When comparing with international registry data, clinical pregnancy rate per transfer from fresh IVF cycles including ICSI (34.1%,) was comparable to clinical pregnancy rate per transfer in European Society for Human Reproduction and Embryology report was 32.5% though lower than 45.0% for USA data. There was no remarkable difference in status of assisted reproductive technology in Korea between the current report and the data reported in 2008. The age of women trying to get pregnant was reconfirmed to be the most important factor that may have impact on success of ART treatment.

Since laparoscopic liver resection was first introduced in 2001, Korean surgeons have chosen a laparoscopic procedure as one of the treatment options for benign or malignant liver disease. We distributed and analyzed a nationwide questionnaire to members of the Korean Laparoscopic Liver Surgery Study Group (KLLSG) in order to evaluate the current status of laparoscopic liver resection in Korea. Questionnaires were sent to 24 centers of KLLSG. The questionnaire consisted of operative procedure, histological diagnosis of liver lesions, indications for resection, causes of conversion to open surgery, and postoperative outcomes. A laparoscopic liver resection was performed in 416 patients from 2001 to 2008. Of 416 patients, 59.6% had malignant tumors, and 40.4% had benign diseases. A total laparoscopic approach was performed in 88.7%. Anatomical laparoscopic liver resection was more commonly performed than non-anatomical resection (59.9% vs 40.1%). The anatomical laparoscopic liver resection procedures consisted of a left lateral sectionectomy (29.3%), left hemihepatectomy (19.2%), right hemihepatectomy (6%), right posterior sectionectomy (4.3%), central bisectionectomy (0.5%), and caudate lobectomy (0.5%). Laparoscopy-related serious complications occurred in 12 (2.8%) patients. The present study findings provide data in terms of indication, type and method of liver resection, and current status of laparoscopic liver resection in Korea.
