Utility of solar-powered oxygen delivery in a resource-constrained setting.

BACKGROUND: Pneumonia is a leading cause of childhood mortality globally. Children with severe pneumonia associated with hypoxaemia require oxygen (O2) therapy, which is scarce across resource-constrained countries. Solar-powered oxygen (SPO2) is a novel technology developed for delivering therapeutic O2 in resource-constrained environments. RESEARCH QUESTION: Is the introduction of SPO2 associated with a reduction in mortality, relative to the existing practice? STUDY DESIGN: This was a pragmatic, quasi-experimental study comparing mortality amongst children < 5 years of age with hypoxaemic respiratory illness before and after the installation of SPO2 in two resource-constrained hospitals. METHODS: Participants were children < 5 years old admitted with acute hypoxaemic respiratory illness. The intervention was SPO2, installed at two resource-constrained hospitals. The primary outcome was 30-day mortality. Secondary outcomes included in-hospital mortality (time to death), length of hospital stay among survivors, duration of O2 therapy (time to wean O2), and O2 delivery system failure(s). RESULTS: Mortality amongst children admitted with acute hypoxaemic respiratory illness decreased from 30/50 (60%) pre-SPO2 to 15/50 (30%) post-SPO2 (relative risk reduction 50%, 95%CI 19 - 69, p = 0.0049). The post-SPO2 period was consistently associated with decreased mortality in statistical models adjusting for potential confounding factors. Likewise, survival curves pre- and post- SPO2 differed significantly (hazard ratio 0.39, 95% CI 0.20 - 0.74, p = 0.0043). A reduction in the frequency of O2 delivery interruptions due to fuel shortages and multiple patients needing the concentrator at once was observed, explaining the mortality reduction. INTERPRETATION: Solar-powered oxygen installation was associated with decreased mortality in resource-constrained settings.

Electrophoretic deposition of polymethylmethacrylate and composites for biomedical applications.

For the first time, an electrophoretic deposition (EPD) method has been developed for the deposition of polymethylmethacrylate (PMMA) and PMMA-alumina films for biomedical implant applications. The proposed biomimetic approach was based on the use of a bile salt, sodium cholate (NaCh), which served as a multifunctional solubilizing, charging, dispersing and film-forming agent. Investigations revealed PMMA-Ch- and PMMA-alumina interactions, which facilitated the deposition of PMMA and PMMA-alumina films. This approach allows for the use of a non-toxic water-ethanol solvent for PMMA. The proposed deposition strategy can also be used for co-deposition of PMMA with other functional materials. The PMMA and composite films were tested for biomedical implant applications. The PMMA-alumina films showed statistically improved metabolic results compared to both the bare stainless steel substrate and pure PMMA films. Alkaline phosphatase (ALP) activity affirmed the bioactivity and osteoconductive potential of PMMA and composite films. PMMA-alumina films showed greater ALP activity than both the PMMA-coated and uncoated stainless steel.

Biomimetic modification of poly-l-lysine and electrodeposition of nanocomposite coatings for orthopaedic applications.

For the first time, a biomimetic method has been developed for the chemical modification of poly-l-lysine (PLL) with catechol in order to improve polymer adhesion to inorganic particles and surfaces. The method is based on the Schiff base reaction of amino groups of PLL monomers and aldehyde groups of 3,4-dihydroxybenzylaldehyde (DHBA) molecules. It was found that adherent PLL-DHBA films can be prepared by cathodic electrophoretic deposition (EPD). Nanocomposite coating with dual micro-nano topography has been developed for orthopaedic and dental coating applications. The catechol groups of PLL-DHBA facilitated its adsorption on hydroxyapatite (HA) and rutile (TiO2) and allowed the fabrication of stable suspensions for EPD. PLL-DHBA was used as both a charging and film-forming agent for EPD of HA and TiO2. Moreover, the methods allowed co-deposition of HA and TiO2 and fabrication of composite films, which allows the benefits of both bioceramics to be combined. In addition to having dual scale topography, the films exhibited both sub-micron surface roughness and hydrophilic behaviour, which both have been found to promote osteoblast adhesion and proliferation. in vitro studies revealed that the fabricated coatings showed increased cell metabolism and alkaline phosphatase activity over the period studied, with PLL-DHBA-TiO2 showing the greatest increase. This work paves the way for both the development of the next generation of biomedical implant coatings, with improved osseointegration and lifespan, as well as one-step low-temperature processing.

Relationship between enteric pathogens and acute gastroenteritis disease severity: a prospective cohort study.

OBJECTIVES: To evaluate the relationship between individual bacterial and viral pathogens and disease severity. METHODS: Children <18 years with three or more episodes of vomiting and/or diarrhoea were enrolled in two Canadian paediatric emergency departments between December 2014 and August 2016. Specimens were analysed employing molecular panels, and outcome data were collected 14 days after enrolment. The primary outcome was severe disease over the entire illness (symptom onset until 14-day follow-up), quantified employing the Modified Vesikari Scale (MVS) score. The score was additionally analysed in two other time periods: index (symptom onset until enrolment) and follow-up (enrolment until 14-day follow-up). RESULTS: Median participant age was 20.7 (IQR: 11.3, 44.2) months; 47.4% (518/1093) and 73.4% (802/1093) of participants had index and total MVS scores ≥11, respectively. The most commonly identified pathogens were rotavirus (289/1093; 26.4%) and norovirus (258/1093; 23.6%). In multivariable analysis, severe disease over the entire illness was associated with rotavirus (OR = 9.60; 95%CI: 5.69, 16.19), Salmonella (OR = 6.61; 95%CI: 1.50, 29.17), adenovirus (OR = 2.53; 95%CI: 1.62, 3.97), and norovirus (OR = 1.43; 95%CI: 1.01, 2.01). Pathogens associated with severe disease at the index visit were: rotavirus only (OR = 6.13; 95%CI: 4.29, 8.75), Salmonella (OR = 4.59; 95%CI: 1.71, 12.29), adenovirus only (OR = 2.06; 95%CI: 1.41, 3.00), rotavirus plus adenovirus (OR = 3.15; 95%CI: 1.35, 7.37), and norovirus (OR = 0.68; 95%CI: 0.49, 0.94). During the follow-up period, rotavirus (OR = 2.21; 95%CI: 1.50, 3.25) and adenovirus (OR = 2.10; 95%CI: 1.39, 3.18) were associated with severe disease. CONCLUSIONS: In children presenting for emergency department care with acute gastroenteritis, pathogens identified were predominantly viruses, and several of which were associated with severe disease. Salmonella was the sole bacterium independently associated with severe disease.

Hepatitis B and C serologic profiles of Canadian organ donors and recipients: retrospective 10-year review at a single center.

BACKGROUND: Hepatitis C virus (HBV) and hepatitis C virus (HCV) are important causes of hepatitis and can be transmitted from organ donor to recipient. This study aimed to determine HBV and HCV serologic profiles of a population of Canadian solid organ transplant (SOT) donors and recipients, including prevalence of recipient HBV immunity. METHODS: Data on age, gender, organ transplanted, and pre-transplant HBV and HCV serology for SOT donors and recipients at a Canadian hospital from 2001 to 2011 were obtained from a transplant database. RESULTS: There were 2455 recipients (2205 adults, 250 children), and 1559 donors. Over 50% of adult and 44% of pediatric recipients were HBV non-immune pre-transplant. Pediatric recipients were more likely to have HBV vaccine immunity than were adult recipients (48.8% vs. 28.9%, P < 0.001). Prevalence of HBV vaccine immunity was highest in renal recipients (48.3% in adult, 63.2% in pediatric recipients). Recipient HBV vaccine immunity increased from 5.8% in 2001 to 44.5% in 2011 (P < 0.001). Of 134 adult recipients with prior HBV infection, 59 (44%) were co-infected with HCV. Only 0.6% of adult non-liver recipients had acute or chronic HBV infection and 3.2% were anti-HCV positive. Only 2 donors had acute or chronic HBV infection, 29 had prior HBV infection, 9 were isolated hepatitis B core antibody positive, and 15 were anti-HCV positive. CONCLUSIONS: The prevalence of HBV vaccine immunity in SOT candidates is low, but increased from 2001 to 2011. Opportunities for quality improvement in pre-transplant HBV immunization exist. HCV co-infection is common in recipients with prior HBV infection. Prevalence of HCV infection in non-liver transplant recipients is low.

Google Flu Trends in Canada: a comparison of digital disease surveillance data with physician consultations and respiratory virus surveillance data, 2010-2014.

The value of Google Flu Trends (GFT) remains unclear after it overestimated the proportion of physician visits related to influenza-like illness (ILI) in the United States in 2012-2013. However, GFT estimates (%GFT) have not been examined nationally in Canada nor compared with positivity for respiratory viruses other than influenza. For 2010-2014, we compared %GFT for Canada to Public Health Agency of Canada ILI consultation rates (%PHAC) and to positivity for influenza A and B, respiratory syncytial virus (RSV), human metapneumovirus (hMPV), and rhinoviruses. %GFT correlated well with %PHAC (ρ = 0·77-0·90) and influenza A positivity (ρ = 0·64-0·96) and overestimated the 2012-2013 %PHAC peak by 0·99 percentage points. %GFT peaks corresponded temporally with peaks in positivity for influenza A and rhinoviruses (all seasons) and RSV and hMPV when their peaks preceded influenza peaks. In Canada, %GFT represented traditional surveillance data and corresponded temporally with patterns in circulating respiratory viruses.

Association between eNOS polymorphisms and risk of coronary artery disease in a Korean population: a meta-analysis.

Coronary artery disease (CAD), a multifactorial disease, is a common cause of mortality in humans. Polymorphisms in the endothelial nitric oxide synthase (eNOS) gene (-786T>C, 4a4b, and 894G>T) have been previously associated with increased CAD risk. However, the sample size of this previous study was too small and limited to comprehensively define an association between eNOS polymorphisms and CAD; therefore, this analysis was duplicated with a larger population. The study was conducted on 559 patients with CAD and 574 healthy controls. Genetic DNA was extracted using the commercial G-DEX blood extraction kit and statistical analyses were performed on the GraphPad prism 4.0 and MedCalc 12.0 statistical software platforms. No single variant of the eNOS polymorphism was associated with CAD risk. The combination genotypes of eNOS -786TT/4a4b+4a4a [adjusted odds ratio (AOR) = 0.122; 95% confidence interval (CI): 0.042-0.358] and eNOS -786TC+CC/4b4b (AOR = 0.379; 95%CI: 0.147-0.979) were associated with decreased CAD incidence. Haplotype analysis revealed that the T-4a haplotype of eNOS -786T>C and 4a4b exerted a protective effect against CAD. The association between eNOS -786T>C and increased CAD risk was not replicated in this (larger) population. However, some combined genotypes showed a meaningful association with CAD risk.

Assessment of human virus removal during municipal wastewater treatment in Edmonton, Canada.

AIMS: To assess the removal of viruses through the multiple steps of wastewater treatment in a full-scale municipal wastewater treatment plant in Alberta, Canada. METHODS AND RESULTS: Samples were collected after each of the five treatment steps for a period of 16 months. The amount of viruses and their infectivity were analysed using real-time quantitative PCR (qPCR) and integrated viral cell culture (ICC), respectively. Bacterial indicator Escherichia coli was also tested using membrane filtration. Seven viruses including Norovirus (NoV), Rotavirus (RV), Sapovirus (SaV), Astrovirus (AsV), Adenovirus (AdV), Enterovirus (EV) and JC virus (JCV) were detected in 16 primary effluents in which infectious viruses were present. Different treatment steps showed various efficiencies in virus removal, with membrane ultrafiltration as the most effective at 4·6-7·0 log reduction. CONCLUSIONS: We observed high prevalence of viruses in raw wastewater and different viral reduction after various treatment steps. The discharge of treated wastewater with infectious viruses represents potential risks to human, animal and environmental health. SIGNIFICANCE AND IMPACT OF THE STUDY: This study provides a comprehensive assessment of the removal of NoV, RV, SaV, AsV, AdV, EV, JCV and Reovirus from wastewater by current procedures of municipal wastewater treatment and discusses the applicability of various viruses as viral indicators for water quality.

Management of gastric epithelial neoplasia in patients requiring esophagectomy for esophageal cancer.

Esophageal squamous cell carcinoma is occasionally associated with malignancies located in other regions of the alimentary tract, as well as in the head, neck, and upper respiratory tract. The stomach is most commonly used for reconstruction of the alimentary tract after esophagectomy for esophageal cancer. When synchronous tumors are located in the stomach, it is often unsuitable for use in esophageal reconstruction. In such cases, an invasive procedure involving anastomosis between the esophagus and the colon must be performed. However, this procedure is associated with a high incidence of mortality and morbidity. Seven patients with synchronous esophageal cancer and gastric epithelial neoplasia were encountered. First, endoscopic submucosal dissection (ESD) was performed for the gastric epithelial neoplasia. Then, following successful ESD, Ivor-Lewis esophagectomy for esophageal cancer was planned 1 to 2 weeks later. A total of 11 gastric epithelial lesions were found in seven patients. En bloc resection by ESD was possible in all 11 lesions and histologically complete resection was achieved in all 11 lesions. Follow-up endoscopy was done 1-2 weeks after ESD; six patients with well-healing ulcers underwent esophagectomy the next day (8 or 15 days after ESD). In one patient with a poorly healed ulcer, a second follow-up endoscopy was done 1 week later and then esophagectomy was performed the next day (22 days after ESD). Post-surgical complications related to ESD, such as bleeding or mediastinal leak, were not seen in any of the seven patients. In patients with synchronous esophageal cancer and gastric epithelial neoplasia, ESD for gastric epithelial neoplasia followed by Ivor-Lewis esophagectomy 1 to 2 weeks later is an effective choice of treatment.

Endoscopic submucosal resection of esophageal subepithelial lesions using band ligation.

Subepithelial lesions (SELs) are occasionally found in the esophagus during upper endoscopy. Sometimes endoscopic resection is needed for accurate diagnosis or in the rare cases of malignant transformation of SELs. In this case series, we evaluated the usefulness of endoscopic submucosal resection with a ligation device (ESMR-L) in esophageal SELs. Twenty-three patients with 25 esophageal SELs that were no larger than 13 mm and were localized within the muscularis mucosae or submucosa were enrolled. ESMR-L was successfully performed in all 25 SELs. The en bloc resection rate was 100% (25/25), and histologically complete resection was achieved in 24 lesions (24/25, 96%). After resection of the lesion by snare, minor immediate bleeding occurred in four cases, but there was no delayed bleeding or perforation.

Respiratory failure associated with human metapneumovirus infection in an infant posthepatic transplant.

This is the first reported case of respiratory failure associated with human metapneumovirus (hMPV) infection in a liver transplant recipient or in a pediatric solid transplant recipient. A 9-month-old female developed respiratory distress 8 days following a liver transplant. hMPV was detected and she required intubation followed by extracorporeal membrane oxygenation for 26 days. Immunosuppressive medications were stopped during the acute infection except for methylprednisolone as treatment for acute respiratory distress. Serial Doppler ultrasounds were used to monitor for hepatic vessel thromboses and serum liver function tests to assess for hepatic dysfunction and there was no evidence of allograft rejection. The patient recovered from the nosocomial hMPV infection with satisfactory pulmonary function and possible mild developmental delay.

Influence of maternal serum levels of vitamins C and E during the second trimester on birth weight and length.

OBJECTIVE: It has been known that maternal oxidative stress during pregnancy plays an important role in fetal growth. However, the association between antioxidant vitamin levels and birth outcomes is not conclusive. We investigated the relationship between maternal serum levels of vitamins C and E during the second trimester and birth weight and length. DESIGN: Prospective cohort study. SETTING: Outpatient-clinic of obstetrics, Ewha Womans University Hospital, South Korea. SUBJECTS AND METHODS: The study subjects were 239 healthy, pregnant women who visited an obstetric clinic for antenatal care, and their singleton live births, in Seoul, Korea, between August 2001 and March 2003. We measured the levels of vitamins C and E in maternal serum during the period 24-28 gestational weeks. Each woman was interviewed for dietary intake by trained interviewers during the second trimester. RESULTS: The serum concentration of maternal vitamin C during the second trimester was significantly associated with birth weight and length in the group of full-term deliveries. An increase of 1 microg/ml in the serum vitamin C level increased the birth weight by 27.2 g and the birth length by 0.17 cm. When we considered the levels of vitamins C and E together in the relationship with birth weight and length, we found that the heaviest birth weight and the longest birth length belonged to the group of upper vitamin C/upper vitamin E. However, dietary intake estimated by 24-h recall method was not a predictor of the levels of serum vitamins C and E. CONCLUSION: We found that maternal serum vitamin C levels during the second trimester were positively correlated with birth weight and length in full-term babies. We also found that birth weight and length were highest when the levels of both vitamins C and E were high. Our results indicate the importance of antioxidant nutrient balance for pregnant women who are exposed to various oxidants through food, drinking water, or inhaled air.

Serum cytokine profiles in patients with Plasmodium vivax malaria: a comparison between those who presented with and without thrombocytopenia.

One of the peculiar features of Plasmodium vivax malaria in South Korea is the surprisingly high frequency of thrombocytopenia. The mechanism by which this malaria-related thrombocytopenia develops and its role in the pathology and progress of human infection with P. vivax have not yet been completely understood. In the present study, the serum cytokine profiles of cases of P. vivax malaria who presented with thrombocytopenia were compared with those of similar cases who did not have thrombocytopenia at presentation. The subjects were the 94 consecutive cases of P. vivax malaria who presented at five hospitals in South Korea (all near the Demilitarized Zone) between May 2000 and October 2002, 47 of whom had thrombocytopenia at presentation. When mean values and (S.E.) were compared, the thrombocytopenic patients were found not only to be generally older than the non-thrombocytopenic [25.3 (1.1) v. 21.3 (0.18) years; P < 0.001] but also to have presented with higher serum concentrations of aspartate aminotransferase [77.6 (16.6) v. 32.3 (7.4) U/litre; P < 0.0001], alanine aminotransferase [96.7 (19.0) v. 44.7 (12.0) U/litre; P = 0.0001], interleukin-1 [49.9 (7.4) v. 23.7 (5.1) pg/ml; P < 0.001], interleukin-6 [174.9 (26.4) v. 57.3 (14.6) pg/ml; P = 0.001], interleukin-10 [308.2 (39.6) v. 137.9 (23.1) pg/ml; P < 0.002] and transforming growth factor-beta [1134.3 (387.5) v. 416.6 (183.8) pg/ml; P < 0.0001], and higher levels of parasitaemia [4345.7 (966.6) v. 1443.8 (222.7) parasites/microl; P = 0.03). The non-thrombocytopenic patients, however, had relatively high total leucocyte counts [5.8 (0.24) v. 5.4 (0.66) leucocytes/nl; P = 0.03]. The thrombocytopenia associated with P. vivax malaria in South Korea therefore appears to be associated with elevated serum concentrations of both pro- and anti-inflammatory cytokines. To define the role of each cytokine in the development of thrombocytopenia during the course of acute P. vivax malaria, further prospective studies are needed.

Exposure to air pollution during different gestational phases contributes to risks of low birth weight.

BACKGROUND: Although there have been growing concerns about the adverse effects of air pollution on birth outcomes, little is known about which specific exposure times of specific pollutants contribute to low birth weight (LBW). METHODS: We evaluated the relationships between LBW and air pollution exposure levels in Seoul, Korea. Using the air pollution data, we estimated the exposure during each trimester and also during each month of pregnancy on the basis of the gestational age and birth date of each newborn. Generalized additive logistic regression analyses were conducted considering infant sex, birth order, maternal age, parental education level, time trend, and gestational age. RESULTS: The monthly analyses suggested that the risks for LBW tended to increase with carbon monoxide (CO) exposure between months 2-5 of pregnancy, with exposure to particles <10 micro m (PM(10)) in months 2 and 4, and for sulphur dioxide (SO(2)) and nitrogen dioxide (NO(2)) exposure between months 3-5. CONCLUSIONS: This study suggests that exposure to CO, PM(10,) SO(2) and NO(2) during early to mid pregnancy contribute to risks for LBW.

Is air pollution a risk factor for low birth weight in Seoul?

Environmental factors contributing to reduced birth weight are of great concern because of the well-known relation of birth weight to infant mortality and adverse effects in later life. We examined the associations between air pollution exposures during pregnancy and low birth weight among all full-term births (gestational age 37-44 weeks) for a 2-year period (January 1996 through December 1997) in Seoul, South Korea. We evaluated these associations with a generalized additive logistic regression adjusting for gestational age, maternal age, parental educational level, parity, and infant sex. We used smoothing plots with generalized additive models to analyze the exposure-response relation for each air pollutant. The adjusted relative risk of low birth weight was 1.08 [95% confidence interval (CI) = 1.04-1.12] for each interquartile increase for carbon monoxide concentrations during the first trimester of pregnancy. The relative risks were 1.07 (95% CI = 1.03-1.11) for nitrogen dioxide, 1.06 (95% CI = 1.02-1.10) for sulfur dioxide, and 1.04 (95% CI = 1.00-1.08) for total suspended particles also for interquartile increase in exposure. Carbon monoxide, nitrogen dioxide, sulfur dioxide, and total suspended particle concentrations in the first trimester of pregnancy period are risk factors for low birth weight.

Exposure to alcohol in utero: Influence on cognitive function and learning in a northern elementary school population.

OBJECTIVES: To establish the prevalence of fetal alcohol exposure; to compare physical, behavioural and learning patterns of children with significant alcohol exposure in utero with those of a group of children exposed to minimal alcohol; to assess the usefulness of a fetal alcohol syndrome (FAS)/fetal alcohol effect (FAE) score; and to provide feedback to parents, schools and communities. DESIGN: Parent questionnaire, complete physical examinations of children, psychometric tests of the children using elements of the Pediatric Early Elementary Examination (PEEX) and the Pediatric Examination of Educational Readiness (PEER), ADD-H comprehensive teachers rating scale (ACTeRS) score, the newly developed FAS/FAE Score, and the Brigance Comprehensive Inventory of Basic Skills to assess language and mathematical achievement. Testers were blinded to the results of the assessments and questionnaires. SETTING: Grades 1 to 3 at Sir Alexander MacKenzie School in Inuvik, Northwest Territories. RESULTS: Twenty-four per cent of mothers reported frequent or binge drinking, and 76% of mothers reported abstinence or moderate alcohol intake. There were significant ethnic differences; none of the Caucasian mothers reported frequent or binge drinking during pregnancy compared with 40% of Inuvialuit and 33% of Indian mothers. Children with exposure to frequent or binge drinking in utero had smaller palpebral fissures (2.3+/-0.1 cm versus 2.5+/-0.3 cm, P<0.01), smaller palpebral fissure to intercanthal distance ratios (0.77+/-0.05 versus 0.86+/-0.10, P<0.01) and smaller head circumferences (52.1+/-1.6 cm versus 53.6+/-1.6 cm, P<0.01) than those exposed to moderate drinking or abstinence. Children exposed to frequent or binge drinking in utero also demonstrated poorer coordination (P<0.005) and cortical function (P<0.01), attention problems, hyperactivity (ACTeRS), and poorer scholastic achievement in language (P<0.001) and mathematics (P<0.01) than their minimally exposed counterparts. In children in grades 2 and 3, a significant negative correlation was found between FAS/FAE scores and language (r=-0.55, P<0.001) and mathematical achievement (r=-0.28, P=0.20). CONCLUSIONS: The prevalence of drinking during pregnancy in the northern population studied was high, and exposure in utero was associated with physical abnormalities, difficulties with coordination and cortical function, and significant delays in language and mathematical achievement. The FAS/FAE score may be useful in predicting success or failure in language development.

Functional studies on the interaction between human replication protein A and Xeroderma pigmentosum group A complementing protein (XPA).

The human replication protein A (RPA; also known as human single-stranded DNA binding protein, HSSB) is a multisubunit complex (70, 34 and 11 kDa subunits) involved in the three processes of DNA metabolism; replication, repair, recombination. We found that both 34 and 70 kDa subunits (p34 and p70, respectively), of RPA interacts with the Xeroderma pigmentosum group A complementing protein (XPA), a protein that specifically recognizes UV-damaged DNA. Our mutational analysis indicated that no particular domains of RPA p70 were essential for its interaction with XPA. We also examined the effect of this XPA-RPA interaction on in vitro simian virus 40 (SV40) DNA replication catalyzed by the crude extract and monopolymerase system. XPA inhibited SV40 DNA replication in vitro through its interaction with RPA. Taken together, these results suggest that there is a role for RPA in the regulation of DNA metabolism through its ability to modulate the interactions of proteins involved in the processes of DNA metabolism.

Comparative study of mortality and morbidity in premature infants (birth weight, < 1,250 g) with candidemia or candidal meningitis.

Little information is available on long-term neurodevelopment of premature neonates with invasive candidal infections. We retrospectively studied the outcomes for 25 premature neonates (birth weight, < 1,250 g) with candidemia or candidal meningitis (cases) and compared them with 25 neonates matched for birth weight (+/- 100 g) and gestational age (+/- 1 week) (controls). Durations of antibiotic therapy, artificial ventilation, invasive catheterizations, and hyperalimentation were longer for cases than for controls. Cases had a higher final grade of intraventricular hemorrhage than did controls (median: 3.0 vs. 2.5, respectively; P < .05). Forty-four percent (11 of 25) of cases and 16% (4 of 25) of controls died (P > .05), and 29% (4 of 14) of surviving cases and 14% (3 of 21) of controls were disabled (P > .05). More cases had combined mortality and neurodevelopmental disabilities than did controls (60% vs. 28%, respectively; P < .05). Use of invasive therapies should be minimized for premature neonates at risk for invasive candidal infection that is associated with adverse outcomes.
