Background: A predominate azole-resistant Candida tropicalis clade 4 genotype causing candidemia has been detected in not only Taiwan but also China, Singapore, and Australia. It can also be detected on fruit surfaces. In addition to determining distribution and drug susceptibilities of pathogenic yeasts in environments of intensive care units of 25 hospitals in Taiwan, we would also like to investigate whether the azole-resistant C.

Background: Poor asthma control may adversely affect mental health. Our study investigates the correlation between inadequate asthma control, exhaled nitric oxide (FENO) levels, and anxiety and depression among pediatric asthma patients with COVID-19.

Methods: This prospective case-control study enrolled 520 asthmatic children (8-15 years), including 336 patients diagnosed with COVID-19 after rapid antigen testing at home and 184 age-matched asthmatic patients without COVID-19 infection.

Background: Taiwan, deeply impacted by the 2003 SARS outbreak, promptly implemented rigorous infection control and prevention (ICP) measures in January 2020 to combat the global COVID-19 pandemic. This cross-sectional serologic study was conducted among healthcare workers (HCWs) in a tertiary care hospital in Taiwan from August 1, 2022, to February 28, 2023. The study aimed to assess HCWs' antibody responses to COVID-19 vaccination against Omicron subvariants BA.

Dengue fever, a mosquito-borne disease in tropical and subtropical climates caused by the dengue virus (DENV), has become a major social and economic burden in recent years. However, current primary detection methods are inadequate for early diagnosis of DENV because they are either time-consuming, expensive, or require training. Non-structural protein 1 (NS1) is secreted during DENV infection and is thus considered a suitable biomarker for the development of an early detection method.

Many countries' curriculum reforms focus on developing the next generations' competencies of self-directed learning (SDL) to address rapid social changes and sustainable environmental development. Taiwan's curriculum reform corresponds with the global trend in education. The latest curriculum reform, which proposed a 12-year basic education, was implemented in 2018 and included SDL explicitly in its guidelines.

Photosynthesis and respiration are two important components of net ecosystem exchange (NEE). NEE can be directly observed by eddy covariance (EC) technique, and statistically separated into ecosystem assimilation and respiration based on the statistical flux partitioning of temperature response function or light-response curves. However, these methods would result in auto-correlation between assimilation and respiration, and overestimate daytime respiration.

Objectives: Inadequate treatment of scrub typhus results in severe complications such as septic shock and is also associated with a high median mortality rate of 6%. However, there has been no conclusive evidence about the superiority of different antibiotics in managing scrub typhus in terms of efficacy and tolerability.

Methods: We conducted a network meta-analysis (NMA) using the frequentist method.

To monitor trends in the distribution of yeast species and the susceptibilities of these species to commonly prescribed antifungal drugs, we conduct the Taiwan Surveillance of Antimicrobial Resistance of Yeasts (TSARY) every 4 years. We found that 25 of 294 Candida tropicalis isolates from TSARY 2014 and 31 of 314 C. tropicalis isolates from TSARY 2018 were resistant to fluconazole.

Despite the increasing health burden of chronic hepatitis B (CHB) in aging populations, little is known about the course of health-related quality of life (HRQoL) changes. We aimed to assess individual-level longitudinal HRQoL changes in elderly patients with CHB and to examine their correlates. A prospective 5.

: Oropharyngeal/esophageal candidiasis are the most common opportunistic infections observed in patients with human immunodeficiency virus (HIV). While the commonly recommended treatment is fluconazole, relapse of oropharyngeal or esophageal candidiasis has been gradually increasing in recent decades.: The current network meta-analysis (NMA) included randomized controlled trials (RCTs) investigating the efficacy and acceptability (i.

Cryptococcal meningitis (CM) is the most fatal adult meningitis in patients with human immunodeficiency virus (HIV). There is no conclusive evidence for the superiority of 1-week amphotericin B deoxycholate (AmphB) + flucytosine (5-FC) regimen over other antifungals in the management of HIV patients with CM (HIV-CM patients). We aimed to evaluate the differences in efficacy and tolerability of different antifungal agents in HIV-CM patients by conducting a current network meta-analysis NMA.

Though infective endocarditis (IE) is a life-threatening cardiac infection with a high mortality rate, the effective diagnostic and prognostic biomarkers for IE are still lacking. The aim of this study was to explore the potential applicable proteomic biomarkers for IE through the Immunome™ Protein Array system. The system was employed to profile those autoantibodies in IE patients and control subjects.

Regulated secretion is a fundamental cellular process in which biologically active molecules stored in long-lasting secretory granules (SGs) are secreted in response to external stimuli. Many studies have described mechanisms responsible for biogenesis and secretion of SGs, but how SGs mature remains poorly understood. In a genetic screen, we discovered a large number of endolysosomal trafficking genes required for proper SG maturation, indicating that maturation of SGs might occur in a manner similar to lysosome-related organelles (LROs).

Article Synopsis
  • - Understanding nasal microbial communities is essential for human health, especially in healthcare institutes, where factors affecting their diversity remain largely unknown.
  • - A study using 16S rRNA sequencing compared nasal and surface microbiota in three healthcare settings, revealing significant differences in diversity and identifying specific dominant taxa.
  • - Hospitalized individuals showed a higher presence of surface microbiota in their nasal samples, indicating potential risks for colonization by harmful microorganisms, thus emphasizing the role of the indoor environment for HCI residents.

Catheter-related bloodstream infections (CRBSIs) and exit-site infections (ESIs) are common complications associated with the use of central venous catheters for hemodialysis. The aim of this study was to analyze the impact of routine locking solutions on the incidence of CRBSI and ESI, in preserving catheter function, and on the rate of all-cause mortality in patients undergoing hemodialysis. We selected publications (from inception until July 2018) with studies comparing locking solutions for hemodialysis catheters used in patients undergoing hemodialysis.

Background: Severe sepsis and pneumonia are common problems in the intensive care units (ICUs) and cause high morbidity and mortality. Optimal doses and appropriate routes of antibiotics are critical to improve their efficacy, but their appropriate routes remain controversial.

Objective: The efficacy of antibiotic administration among critically ill patient populations remains controversial.

Recent findings from an animal experiment suggest a modest association between silymarin and decreased risk of contrast-induced nephropathy. However, the relationship between silymarin and contrast-induced nephropathy in patients with liver cirrhosis remains unclear.From 1997 to 2007, we identified 3019 patients with liver cirrhosis who were administered silymarin and matched them with 3019 patients with liver cirrhosis who were not administered silymarin.

The prevalence of carbapenem-resistant Klebsiella pneumoniae (CRKP) was up to 30% between 2014 and 2016 in the study hospital. Of these 77 CRKP isolates, 22 isolates with sequence type ST11 carried the new pKPC_P16 plasmid, a pKPC_LK30 variant, and were widely disseminated between 2014 and 2015 in northern Taiwan.
