Candidemia due to uncommon Candida species in children: new threat and impacts on outcomes.

Many uncommon Candida spp. (species other than C. albicans, C. parapsilosis, C. glabrata, C. tropicalis, and C. krusei) have been shown to emerge in tertiary care facilities. We aimed to investigate these uncommon candidemia in children. Forty-six cases of candidemia caused by uncommon Candida spp. were identified during 2003-2015 from a medical center in Taiwan. The most common specie was C. guilliermondii (31.2%), followed by C. lusitaniae (18.8%) and C. metapsilosis (18.8%). These cases were analyzed and compared with 148 episodes of C. albicans candidemia. The incidence density of uncommon Candida spp. candidemia and the proportion to all candidemia episodes increased substantively during the study period. Prior exposure to azoles was uncommon in the 30 days prior to infection, but fluconazole resistant strains were significantly more common (n = 19, 41.3%). The increased incidence density of uncommon Candida spp. candidemia was associated with increasing use of antifungal agents. No differences in demographics, underlying comorbidities, risk factors, clinical features, dissemination, and 30-day mortality were found between uncommon Candida spp. and C. albicans candidemia. Patients with uncommon Candida spp. candidemia were more likely to require modifications in antifungal treatment and receive echinocandin drugs (43.5% vs 21.6%, p = 0.007). Candidemia caused by uncommon Candida spp. had poorer response to antifungal treatment, led to longer duration of candidemia (median 4.0 versus 2.5 days, p = 0.008), and had a higher treatment failure rate (56.5% vs 38.5%, p = 0.040).

Prevalence and morbidity of late preterm infants: current status in a medical center of Northern Taiwan.

BACKGROUND: "Late preterm" defines infants born at 34(0/7) through 36(6/7) weeks' gestation, which comprise a majority of preterm births. These infants were treated clinically as "near-term" in the past, but recent studies have implied increased morbidities that differentiate late preterm and term infants. The purpose of this study was to examine the prevalence and clinical complications that could be associated with late preterm birth, as compared to term. METHODS: This was a retrospective cohort study that reviewed infants born in a medical center in Northern Taiwan during a 2-year period between 2008 and 2009. Maternal obstetrical factors, neonatal demographic distributions, and neonatal complications were compared between full-term and late preterm deliveries. RESULTS: During the study period, there were 7998 live births in the institute, including 6507 term and 1491 preterm infants. Of the latter, there were 914 (61.3%) born after 34 weeks' gestation. The Neonatal Intensive Care Unit (NICU) (including a special care nursery) admission rate was higher in late preterm infants when compared to term (36% vs. 2%), and was 74%, 43%, and 21% in infants born at 34, 35, and 36 weeks' gestation, respectively. Compared with term infants, late-preterm infants had longer hospital stay if admitted to NICU (including special care nursery) (17 days vs. 10 days), and they were associated with increased risk of neonatal morbidities, including respiratory distress syndrome (2.6% vs. 0.02%), respiratory distress of other etiologies (16% vs. 2%), culture-proven sepsis (0.7% vs. 0.2%), hypoglycemia (3% vs. 0.4%), temperature instability (0.4% vs. 0.05%), feeding difficulty (2% vs. 0.4%), and hyperbilirubinemia needing phototherapy (14% vs. 3%). Late-preterm infants also had higher hospital readmission rate (4.4% vs. 2.3%, p<0.001) and neonatal mortality rate (0.3% vs. 0.08%, p=0.03). CONCLUSION: Late-preterm infants have increased risk of neonatal morbidities associated with organ immaturity. The results of this study emphasize the importance of judicious obstetrical decision-making when considering late preterm delivery, and the need to set up anticipatory clinical guidelines for the care of late preterm infants.
