Mixed bloodstream infections (BSIs) involving and other bacterial pathogens present significant diagnostic and therapeutic challenges. The incidence of these co-infections has been increasing. However, the limited literature on this topic necessitates a deeper understanding of its epidemiological and clinical characteristics.

Background: People living with HIV (PLWH) are at increased risk for metabolic disorders, including diabetes and prediabetes. While hemoglobin A1c (HbA1c) is widely used for glycemic assessment, its reliability in PLWH is questioned due to altered red blood cell turnover. Glycated albumin (GA) has been proposed as an alternative, but its diagnostic utility remains unclear in PLWH.

Background: Adherence to antiretroviral therapy (ART) is critical for successful viral suppression in people living with HIV (PLHIV). The comparative effectiveness of two-drug regimens (2DRs) versus three-drug regimens (3DRs)-particularly in Asian populations-is an underexplored topic.
Methods: This retrospective cross-sectional study was conducted at two hospitals in Taiwan between November 2023 and January 2025.

Sexually transmitted infections (STIs) continue to pose major public health challenges globally, with millions of new cases reported annually. The asymptomatic characteristic of many STIs makes accurate and cost-effective diagnostic methods essential for screening and diagnosis. This paper evaluates the utility of enzyme-linked immunosorbent assays (ELISAs) in diagnoses of HIV, HPV, HSV, HBV, HCV, Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis and Treponema pallidum.

Additionally, we assessed the performance of the Sensititre YeastOne (SYO) assay compared to the reference Clinical and Laboratory Standards Institute (CLSI) broth microdilution (BMD) method for antifungal susceptibility testing. A total of 267 clinical isolates were collected from multiple centers in Taiwan between 2008 and 2020.

Exploring the burden and predictors of latent tuberculosis infection (LTBI) and treatment outcomes for older individuals with COPD is essential to guide LTBI intervention policy. We enrolled patients aged over 60 years with COPD between January 2021 and June 2023 for LTBI screening using interferon-gamma release assay (IGRA).

Current laboratory diagnostic techniques for invasive aspergillosis (IA), such as fungal cultures and enzyme immunoassay (EIA) for the galactomannan antigen (GM), are limited by their low sensitivity, labor-intensive nature, and prolonged processing times. Some lateral flow assays (LFAs) have been developed for the diagnosis of IA; however, clinical validation and comparative studies are lacking. This study assessed the diagnostic performance of two CE-marked GM-LFAs, IMMY-GM-LFA and QuicGM-LFA.

We conducted a multicenter, retrospective study to investigate the clinical characteristics, microbiology, and outcomes of patients treated with CAZ-AVI for Gram-negative bacterial infection in Taiwan.
Methods: This investigation was conducted as a multicenter retrospective cohort study involving five medical centers in Taiwan.
Background: It is generally believed that HIV-1 capsid inhibitor-naïve populations are susceptible to capsid inhibitors. Moreover, conventional HIV-1 resistance genotyping does not include the CA region, leading to limited surveillance data.
Methods: We conducted a retrospective study to investigate the presence of mutations at positions associated with capsid inhibitor resistance before the introduction of the first HIV-1 capsid inhibitor, lenacapavir, in Taiwan.
Healthcare-associated infections (HAIs) significantly increase morbidity, mortality, length of hospital stays, and costs, particularly among ICU patients. Despite standard interventions, catheter-associated urinary tract infections (CAUTI) and central line-associated bloodstream infections (CLABSI) remain major HAI contributors. This study evaluated the efficacy of daily 2% chlorhexidine gluconate (CHG) bathing in reducing HAI incidence, specifically CAUTI, CLABSI, and multidrug-resistant organisms (MDROs), in a 20-bed ICU at a regional hospital.

Patient-reported outcomes (PROs) facilitate communication between patients and providers, enhancing patient-centered care. We report PROs for virologically suppressed people living with HIV-1 who switched to dolutegravir/lamivudine (DTG/3TC) or continued their 3- or 4-drug current antiretroviral regimen (CAR) in the phase 3 SALSA study. Secondary endpoints included change from baseline in HIV Treatment Satisfaction Questionnaire (status version; HIVTSQs) and HIV Symptom Distress Module (HIV-SDM) at Weeks 4, 24, and 48.

The novel 1HP regimen, involving daily rifapentine plus isoniazid for 28 days, has demonstrated low toxicity in HIV-infected populations. We aimed to investigate whether 1HP has a lower incidence rate of systemic drug reaction (SDR) compared with 3HP during treatment in non-HIV populations.

Background: Although indicator condition (IC)-guided HIV testing (IC-HIVT) is effective at facilitating timely HIV diagnosis, research on IC categories and the related HIV risk in Taiwan is limited. To improve the adoption and spread of IC-HIVT in Taiwan, this study compared the IC categories of people living with HIV (PLWH) and non-HIV controls and investigated delays in the diagnosis of HIV infection.
Methods: This nationwide, retrospective, 1:10-matched case-control study analyzed data from the Notifiable Diseases Surveillance System and National Health Insurance Research Database to evaluate 42 ICs for the 5-year period preceding a matched HIV diagnostic date from 2009 to 2015.
Objectives: The trailing effect of Candida species is a phenomenon characterized by reduced but persistent growth at antifungal concentrations above the MIC. We assessed the impact of trailing growth on the persistence of Candida albicans candidemia in patients receiving fluconazole (FLC) therapy.
