Background/Aims: Data on treatment efficacy and safety of glecaprevir/pibrentasvir (GLE/PIB) for chronic hepatitis C virus (HCV) infection in Asian patients with severe renal impairment are limited. This study aimed to study the treatment and side effects of GLE/PIB in these patients infected with non-1 genotype (GT) HCV. Methods: We prospectively recruited patients with Child’s A cirrhosis and eGFR <30 mL/min/1.73 m2 in Hong Kong and Taiwan during 2017–2018 to receive GLE/PIB treatment. Results: Twenty-one patients (GT2, n=7; GT3, n=6; and GT6, n=8) received GLE/PIB for 11.2±1.8 weeks. All except one were treatment-naïve. GLE/PIB was initiated in 16 patients while on dialysis (seven on peritoneal dialysis [PD] and nine on hemodialysis) and in five patients before dialysis. One patient died of PD-related peritonitis during treatment and two were lost to follow up. The SVR12 rate in the remaining 18 patients was 100%. All patients achieved undetectable levels at 4-, 12-, 24- and 48-week after treatment. Patients with deranged alanine aminotransferase showed normalization after 4 weeks and the response was sustained for 48 weeks. No significant adverse event was observed. Conclusions GLE/PIB treatment was associated with high efficacy and tolerability in HCV-infected patients with severe renal impairment.

It is largely unknown whether lower urinary tract symptoms (LUTS) or acute retention of urine (AROU) is linked to shorter life expectancy in men. We conducted a multicenter, retrospective database analysis of patients undergoing transurethral resection of prostate (TURP) to study their relationships. Multivariate Cox regression analysis and Kaplan-Meier analysis with stratification to age and indication of TURP were performed. We further performed an age- and sex-matched survival analysis with the general population using data from the Census and Statistics Department of the Hong Kong Special Administrative Region (Hong Kong, China). From January 2002 to December 2012, 3496 patients undergoing TURP were included in our study, with 1764 patients in the LUTS group and 1732 patients in the AROU group. Old age, ischemic heart disease, cerebrovascular accident, and AROU were risk factors of mortality. Patients aged 70 years (adjusted hazard ratio [HR]: 1.52, 95% confidence interval [CI]: 1.11-2.09, P = 0.010) and 70-80 years (adjusted HR: 1.39, 95% CI: 1.15-1.70, P = 0.001) in the AROU group had worse survival than those in the LUTS group, but such difference was not demonstrated in patients aged 80 years. Compared to the general population, younger patients in the LUTS group appeared to have better survival (70 years, P = 0.091; 70-80 years, P = 0.011), but younger patients in the AROU group had worse survival (70 years, P = 0.021; 70-80 years, P = 0.003). For patients aged 80 years, survival was similar with the general population in both the LUTS and AROU groups. In conclusion, AROU at young age was associated with mortality, while early detection and management of LUTS may improve survival.

BACKGROUND: Overweight, obesity, and cardiovascular disease risk factors are prevalent among firefighters in some developed countries. It is unclear whether physical activity and cardiopulmonary fitness reduce cardiovascular disease risk and the cardiovascular workload at work in firefighters. The present study investigated the relationship between leisure-time physical activity, cardiopulmonary fitness, cardiovascular disease risk factors, and cardiovascular workload at work in firefighters in Hong Kong. METHODS: Male firefighters (n = 387) were randomly selected from serving firefighters in Hong Kong (n = 5,370) for the assessment of cardiovascular disease risk factors (obesity, hypertension, diabetes mellitus, dyslipidemia, smoking, known cardiovascular diseases). One-third (Target Group) were randomly selected for the assessment of off-duty leisure-time physical activity using the short version of the International Physical Activity Questionnaire. Maximal oxygen uptake was assessed, as well as cardiovascular workload using heart rate monitoring for each firefighter for four "normal" 24-hour working shifts and during real-situation simulated scenarios. RESULTS: Overall, 33.9% of the firefighters had at least two cardiovascular disease risk factors. In the Target Group, firefighters who had higher leisure-time physical activity had a lower resting heart rate and a lower average working heart rate, and spent a smaller proportion of time working at a moderateintensity cardiovascular workload. Firefighters who had moderate aerobic fitness and high leisuretime physical activity had a lower peak working heart rate during the mountain rescue scenario compared with firefighters who had low leisure-time physical activities. CONCLUSION: Leisure-time physical activity conferred significant benefits during job tasks of moderate cardiovascular workload in firefighters in Hong Kong.

OBJECTIVETo examine the Eastern-Western difference in the interpretation of Integrative Medicine Attitude Questionnaire (IMAQ) by assessing the psychometric properties of a revised Chinese medicine (CM)-specific version of IMAQ (CM-IMAQ).

METHODSFactor and Rasch analysis were performed with data collected from a mail survey of 165 Hong Kong Western medical doctors (WMD) randomly sampled from the official registry. The structural validity, unidimensionality, item fit, and differential item functioning (DIF) of the Hong Kong CM-IMAQ were evaluated.

RESULTSConfirmatory factor analysis (CFA) demonstrated that the original IMAQ factor structure was not concordant with our data on Chinese WMD, and subsequent explanatory factor analysis (EFA) validated a new three-factor model for CM-IMAQ: (1) attitude towards "tonification", (2) attitude towards the effectiveness of CM, and (3) attitude towards CM knowledge. The original IMAQ factor on holism and doctor-patient relationship disappeared. Rasch analysis confirmed the unidimensionality of "tonification" and the effectiveness domains, but further refinement of the knowledge domain is needed.

CONCLUSIONSCultural adaptation of the IMAQ has demonstrated differences between Eastern and Western doctors trained in allopathic medicine in their interpretations of holism in healthcare. For Chinese WMD, the emphasis of holistic care is placed on "tonifying" the body rather than on nurturing the mind and spirit. Confucian and Taoist conceptualizations of mental health as well as the persistent stigma towards mental illness within modern Chinese culture may explain why Chinese WMD do not regard mental health promotion as part of routine healthcare.

OBJECTIVES: To compare results of 4 different extraction methods in laparoscopic management of dermoid cyst. STUDY DESIGN: This article is a retrospective, multicenter study for 247 patients with benign dermoid cyst in period of 1995-1998. Dermoid cyst was extracted by Endopouch (99 cases), puncture-irrigation-extraction (69 cases), colpotomy (35 cases), and dermoid cyst as a "pouch bag" (44 cases). RESULTS: We analyzed irrigation amount, operative time, postoperative hospital stay and complications by four different extraction methods. Endopouch extraction method needed less amount of irrigation fluid for cleaning the abdominal cavity and had a shorter postoperative hospital stay (ANOVA, p=0.0001). There were no significant differences in operative times among groups. There were four cases of morbidity in puncture-irrigation-extraction method (6%), three had fever (> 38degrees C) and one intraabdominal abscess. One incisional hernia was noted in "pouch bag" method (2%). CONCLUSIONS: We recommend minimal spillage method for extraction of dermoid and careful irrigation of abdominal cavity to prevent potential risk of chemical peritonitis such as Endopouch, "pouch bag", and colpotomy with the exception of puncture-irrigation-extraction method.

OBJECTIVE: To evaluat the effects of a culture medium with glucose in the presence of glutamine on the development of mouse embryos. METHODS: Two-cell embryos recovered from ICR mice at 48 hrs after hCG injection (mated just after hCG injection) were cultured in DMEM (with 20% hFF) supplemented with or without glucose on the presence of glutamine. Embryos were cultured under three different glucose regimens: (1) 0 mM (control); (2) 0.5 mM (group I); or (3) 3.15 mM (group II), and were analyzed at 24, 48, 72 and 96 hours intervals. Chi-square test (x2-test) was used to compare values of groups. RESULTS: No differences were found in the number of embryos showing morula (control: 37.5%; group I: 51.0%; group II: 48.4%), blastocyst (control: 21.5%; group I: 33.3%; group II: 34.4%) and blastocyst and hatching or hatched blastocyst (control: 81.9%; group I: 83.3%; group II: 82.8%) between groups at 24 hrs, 48 hrs or 72 hrs respectively. However at 96 hrs, the number of hatched and attached blastocyst was significantly higher in group I (82.3%) and II (78.5%) than control (63.2%; P<0.05). CONCLUSION: The addition of glucose (0.5 mM) to the DMEM, as energy source, improved the rate of development of late stage embryos in mice.

Cesarean hysterectomy is associated with high risks of severe blood loss, postoperative complication, and maternal morbidity. This study was undertaken to identify the risk factors of cesarean hysterectomy and to reduce the postoperative complications and maternal morbidity. There were 6,362 deliveries between January 1992 and December 1996 at department of obstetrics and gynecology, Inchon Christian Hospital. 1'he results of this study were as follows, 15 cases of cesarean hysterectomy were performed during this period. Cesarean hysterectomy was performed in 10 cases (0.32 %) among 3178 cesarean deliveries and in 5 cases (0.16 %) among 3184 vaginal deliveries. The incidence of cesarean hysterectomy was 0.24 % (15/6,362). The age of patients ranged from 24 to 38 years old. The maternal mortality and morbidity were 0 % (0/15) and 86.7% (13/15), respectively. Indications for cesarean hysterectomy were uterine atony (53.3 %), uterine myoma with pregnancy (20.0 %), placenta accreta and/or increta(20.0 %), and placenta previa (6.7 %) in orders. The associated risk factors of cesarean hysterectomy were prior cesarean delivery (46.7 %) and placenta previa (6.7 %). The postoperative complications were anemia (60.0%), febrile morbidity (13.3 %), paralytic ileus (6.7 %), and wound disruption (6.7 %). We concluded that risk factors of cesarean hysterectomy were cesarean delivery, prior cesarean delivery, uterine myoma with pregnancy, placenta accreta and/or increta, and placenta previa and that sufficient fresh blood and careful prenatal care were needed in risk group of postpartum bleeding.

The objective of this study is to identify any differences in disease status between foreign patients staying in Korea and Korean patients. The study results are : First, more foreign stayers than Korean in their 20's and 30's seek medical services but those after age of 60 show the opposite pattern. This difference seems to feflect cultural difference in the concept of medical services and health seeking behavior. Second, foreign pateints were much more frequently(almost threee times) diagnosed as having an acute disease, and the fact that the most common diseases were "diseases of the respiratory system" can suggest the seriousness of air pollution problem in Korea. And, the fact that foreign stayers, especially those from developed countries, tend to take more periodic general physical examina-tion indicated that their health maintenance efforts place emphasis on prevention. Foreign patients seek more medical services during the spring and summer time when compared to Korean patients, and Korean patients visited the clinic more frequently during the autum time. Also, the review of the number of outpatients seeking medical services and the average duration of outpatient follow-up mainten-ance after discharge suggest that foreigners suffer less severe diseases than Koreans do. Finally, in contrast to the usual practice of Koreans of coming to the center without prior calling for reservation, most foreign patients tend to make reservations before coming(usually a day before) in general. This is also reflective of cultural difference related to the way of utilizing medical services.
