Purpose: This study evaluated the postoperative quality of life (QoL) after various types of gastrectomy for gastric cancer. Materials and Methods: A multicenter prospective observational study was conducted in Korea using the Korean Quality of Life in Stomach Cancer Patients Study (KOQUSS)-40, a new QoL assessment tool focusing on postgastrectomy syndrome. Overall, 496 patients with gastric cancer were enrolled, and QoL was assessed at 5 time points: preoperatively and at 1, 3, 6, and 12 months after surgery. Results: Distal gastrectomy (DG) and pylorus-preserving gastrectomy (PPG) showed significantly better outcomes than total gastrectomy (TG) and proximal gastrectomy (PG) with regard to total score, indigestion, and dysphagia. DG, PPG, and TG also showed significantly better outcomes than PG in terms of dumping syndrome and worry about cancer. Postoperative QoL did not differ significantly according to anastomosis type in DG, except for Billroth I anastomosis, which achieved better bowel habit change scores than the others. No domains differed significantly when comparing double tract reconstruction and esophagogastrostomy after PG. The total QoL score correlated significantly with postoperative body weight loss (more than 10%) and extent of resection (P<0.05 for both).Reflux as assessed by KOQUSS-40 did not correlate significantly with reflux observed on gastroscopy 1 year postoperatively (P=0.064). Conclusions Our prospective observation using KOQUSS-40 revealed that DG and PPG lead to better QoL than TG and PG. Further study is needed to compare postoperative QoL according to anastomosis type in DG and PG.

The study of human immunodeficiency virus (HIV) infection during pregnancy is of great significance because most women are first diagnosed with HIV during pregnancy. Similarly, it is equally important in cases where one or both partners are HIV-positive and wish to conceive. Since the first case of HIV was reported in the 1980s, antiviral drugs have been developed to prevent progression to acquired immunodeficiency syndrome (AIDS), which allows many AIDS patients to be asymptomatic or have only mild symptoms. This case shows that consecutive pregnancies and births are possible through proper antiretroviral therapy along with regular prenatal examinations in HIV-positive women.Rather than recommending contraception or expressing negative opinions about pregnancy in HIV-infected couples, active HIV treatment and prenatal care should be conducted to support a safe pregnancy and lower the chance of vertical HIV transmission. Recently, there has been a case report on successive childbirths of HIV-positive pregnant women who continued to receive antiretroviral therapy after their first childbirth at our hospital. Through this case, we report that safe delivery of HIV-infected mothers is possible, and further subsequent childbirths can be achieved with the use of appropriate antiretroviral therapy.

This study was performed to evaluate the antibacterial activity of water-soluble mangostin derivatives (WsMD) of the ethanol extract of the peel of Garcinia mangostana L. (mangosteen) and the ethanol extracts of the fruit of Psoralea corylifolia L. and the root of Glycyrrhiza uralensis (licorice) against oral bacteria associated with endodontic infections. Cytotoxicity of the three natural products was tested on human embryonic kidney 293 cells (HEK 293) using the methylthiazolyldiphenyl-tetrazolium bromide (MTT) assay or the cell counting method. Antimicrobial activity was evaluated based on the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). The highest concentrations of the WsMD of the ethanol extract of the peel of mangosteen and ethanol extracts of P. corylifolia L. fruit and licorice root without cytotoxic effects on HEK 293 cells were 20, 400, and 320 µg/ml, respectively. The MIC and MBC values of the WsMD of the ethanol extract of the peel of mangosteen and ethanol extracts of P. corylifolia L. fruit against 35 isolates (23 species) of pulpitis- and periapical disease-causative bacteria were 1.25–20 µg/ml and 25–200 µg/ml, respectively, except for Dialister invisus KCOM 1973. The ethanol extract of licorice root had MBC values of 40–320 µg/ml against 27 of 35 bacterial strains. These results showed that the WsMD of the ethanol extract of mangosteen peel had the highest antibacterial activity among the three natural extracts and suggested it as a potential root canal irrigation agent.
