Taiwan has been facing a rising epidemic of human immunodeficiency virus (HIV) infection since 2004. Injection drug users comprised 38.5% of accumulated HIV cases by 2007. This cross-sectional study investigated the seroprevalence of hepatitis B virus (HBV), hepatitis C virus (HCV), hepatitis D virus (HDV), and HIV infection in 753 male substance users who(More)
The long-term protective effect of hepatitis B virus (HB) vaccination against HB infection and the necessity for routine booster vaccination in young-adult age subsequent to full HB immunization at birth remain issues of some debate currently. This study is aimed at evaluating the seroprevalence of HB infection and the response to HB booster vaccination(More)
BACKGROUND AND OBJECTIVES Methicillin-resistant Staphylococcus aureus (MRSA) nasal carriage is a recognized risk factor for subsequent endogenous infections. However, the association between MRSA carriage and patient survival in hemodialysis patients has not been established. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS In March 2007, this prospective(More)
Blastocystis hominis is probably the most common protozoan found in the human gut worldwide. In Taiwan, the prevalence of B. hominis infection is yet to be determined but is expected to be relatively higher among foreign workers. No data is available on the prevalence of B. hominis infection in long-term care facilities in Taiwan. This study included 713(More)
Time to positivity (TTP) of blood cultures in patients with bacteraemia is considered to be a predictor of outcome for some bacterial species. Two hundred and thirty-one patients with Klebsiella pneumoniae monomicrobial bacteraemia at a hospital from 1 January to 31 December 2007 were prospectively enrolled. TTP <7 h (46 patients, 19.9%) was associated with(More)
In Taiwan, the nation-wide Hepatitis-B virus (HB) vaccination program was first launched in July 1984 and was directed to those infants born to hepatitis B surface antigen (HBsAg) carrier mothers in Taiwan. From July 1986 onwards, all infants born in Taiwan were immunized against HB. This study examined the HB-infection status amongst students at a(More)
Homosexual men infected with human immunodeficiency virus (HIV) are at a greater risk of developing anal cancer. Men who are infected with HIV and visited the outpatient clinics in Taoyuan General Hospital were enrolled to this study. During March to December 2011, thin preparation anal Pap smear and human papillomavirus (HPV) genotyping were performed in(More)
This study was intended to delineate the role of carbapenems and piperacillin/tazobactam in treating bacteremia caused by extended-spectrum β-lactamase (ESBL)-producing Proteus mirabilis. We performed a multicenter and retrospective study of the patients with ESBL-producing P. mirabilis bacteremia. The outcomes of the patients treated by(More)
Although the use of GC agar for determining Neisseria gonorrhoeae antimicrobial susceptibilities is suggested by Clinical and Laboratory Standard Institute (CLSI) guidelines, chocolate agar is still used in some regions owing to its low cost and availability. To determine the differences in susceptibilities determined using GC and chocolate agars, 163(More)
BACKGROUND Patients with chest pain contribute substantially to emergency department attendances, lengthy hospital stay, and inpatient admissions. A reliable, reproducible, and fast process to identify patients presenting with chest pain who have a low short-term risk of a major adverse cardiac event is needed to facilitate early discharge. We aimed to(More)
