BACKGROUND: In a new influenza pandemic, travel data such as arrival times of cases seeded by the originating country can be regarded as a combination of the epidemic size and the mobility networks of infections connecting the originating country with other regions. It can be a complete and timely source for estimating the basic reproduction number (R 0 ), a key indicator of disease transmissibility. METHOD: In this study, we developed a likelihood-based method using arrival times of infected cases in different countries to estimate R 0 for influenza pandemics...

PURPOSE: To evaluate incidence and risk factors of peripherally inserted central catheter (PICC)-related complications in cancer patients. METHODS: A prospective, multicenter, cohort study of cancer patients with PICC insertion was performed from February 1, 2013 to April 24, 2014. All patients were monitored in clinic until PICCs were removed. The primary endpoint was PICC removal due to complications. Patient-, catheter- and insertion-related factors were analyzed in univariable and multivariable logistic regression analysis to identify significant independent risk factors for PICC-related complications...

OBJECTIVE: The rates of central line-associated bloodstream infections (CLABSIs) in United States intensive care units (ICU) have decreased significantly, and a parallel reduction in the rates of total hospital onset bacteremias in these units should also be expected. We report 10-year trends for total hospital onset ICU-associated bacteremias at a tertiary care academic medical center. DESIGN: This was a retrospective analysis of all positive blood cultures among patients admitted to seven adult ICUs for the period FY2005 through FY2014 according to Centers for Disease Control and Prevention National Healthcare Safety Network definitions...

BACKGROUND: The use of catheter hub decontamination protocols is a common practice to reduce central line-associated bloodstream infections. However, few data exist on the most effective disinfection procedure prior to hub access accounting for human factors and time-dependent practices in real time in the clinical setting. METHODS: An observational design with a multimodal intervention was used in this study in a neonatal intensive care unit. Direct observations on nurse compliance of scrub times with decontamination when accessing of venous catheter and feeding tube hubs were conducted during 3 phases: (1) baseline period prior to any interventions; (2) during an educational intervention phase; and (3) during a timer intervention period when using a timing device, either an actual timer or music button...

BACKGROUND: Adverse events (AEs) in acute care hospitals are frequent and associated with significant morbidity, mortality, and costs. Measuring AEs is necessary for quality improvement and benchmarking purposes, but current detection methods lack in accuracy, efficiency, and generalizability. The growing availability of electronic health records (EHR) and the development of natural language processing techniques for encoding narrative data offer an opportunity to develop potentially better methods...

Central-line bloodstream infection (CLABSI) increases hospital mortality. A cohort study was conducted in a Brazilian hospital to estimate the disability-adjusted life year (DALY) of CLABSI using modified World Health Organization (WHO) methodology. CLABSI DALY was 20.44 per 1,000 inpatients, most were the result of premature death (20.42 per 1,000 inpatients). DALY can be useful to guide and measure the impact of healthcare infection prevention. Infect Control Hosp Epidemiol 2017;1-4.

Candida parapsilosis may be responsible for bloodstream infections (BSI) and it is characterised by an increased incidence of fluconazole resistance. A 75-year old woman with severe comorbidities received the insertion of a peripherally inserted central venous catheter. Fluconazole did not prevent a C. parapsilosis BSI hence caspofungin was started after a nephrotoxic first-line treatment with amphotericin B. The ratio of peak plasma concentration over the minimum inhibitory concentration (Cmax/MIC) was adopted to maximise efficacy of caspofungin...

Human herpes simplex virus-1 (HSV-1) is a wide spread pathogen with 80% of the population being latently infected. To successfully evade the host the virus has evolved strategies to counteract antiviral responses, including the gene silencing and innate immunity machineries. The immediately early protein of the virus, Infected Cell Protein 0 (ICP0) plays central role in these processes. ICP0 blocks innate immunity and one mechanism is by degrading hostile factors with its intrinsic E3 ligase activity. ICP0 functions also as a promiscuous transactivator and it blocks repressor complexes to enable viral gene transcription...

The use of central venous catheters (CVCs) in children is escalating, which is likely linked to the increased incidence of pediatric venous thromboembolism (VTE). In order to better understand the specific risk factors associated with CVC-VTE in children, as well as available prevention methods, a literature review was performed. The overall incidence of CVC-VTE was found to range from 0 to 74%, depending on the patient population, CVC type, imaging modality, and study design. Throughout the available literature, there was not a consistent determination regarding whether a particular type of central line (tunneled vs...

BACKGROUND: Multiple toll-like receptors (TLRs) are expressed in cells of the monocytic lineage, including microglia, which constitute the major reservoir for human immunodeficiency virus (HIV) infection in the brain. We hypothesized that TLR receptor mediated responses to inflammatory conditions by microglial cells in the central nervous system (CNS) are able to induce latent HIV proviruses, and contribute to the etiology of HIV-associated neurocognitive disorders. RESULTS: Newly developed human microglial cell lines (hµglia), obtained by immortalizing human primary microglia with simian virus-40 (SV40) large T antigen and the human telomerase reverse transcriptase, were used to generate latently infected cells using a single-round HIV virus carrying a green fluorescence protein reporter (hµglia/HIV, clones HC01 and HC69)...

Health care-associated infections (HAIs) are the primary cause of preventable death and disability among hospitalized patients. According to the Centers for Disease Control and Prevention (CDC), complications or infections secondary to either device implantation or surgery are referred to as HAIs. Specifically, the CDC monitors surgical site infections, central-line-associated bloodstream infection, catheter-associated urinary tract infections, and ventilator-associated pneumonias. This article explores HAIs specific to pathophysiology, epidemiology, and prevention, and how nurses can work together with other health care providers to decrease the incidence of these preventable complications...

Several nucleic acid-based assays have been developed for detecting Anaplasma marginale and Anaplasma centrale in vectors and hosts, making the choice of method to use in endemic areas difficult. We evaluated the ability of the reverse line blot (RLB) hybridisation assay, two nested polymerase chain reaction (nPCR) assays and a duplex real-time quantitative polymerase chain reaction (qPCR) assay to detect A. marginale and A. centrale infections in cattle (n = 66) in South Africa. The lowest detection limits for A...

In the last years, neurological complications related to Zika virus (ZIKV) infection have emerged as an important threat to public health worldwide. ZIKV infection has been associated to neurological disorders such as congenital microcephaly in newborns and Guillain-Barré syndrome, myelopathy and encephalitis in adults. ZIKV is characterized by neurotropism and neurovirulence. Several studies have identified microglial nodules, gliosis, neuronal and glial cells degeneration and necrosis in the brain of ZIKV infected infants, suggesting that ZIKV could play a role in these neurological disorders through neuroinflammation and microglial activation...

Saprochaete and Geotrichum spp. are rare emerging fungi causing invasive fungal diseases in immunosuppressed patients and scarce evidence is available for treatment decisions. Among 505 cases of rare IFD from the FungiScope(™) registry, we identified 23 cases of invasive infections caused by these fungi reported from 10 countries over a 12-year period. All cases were adults and previous chemotherapy with associated neutropenia was the most common co-morbidity. Fungaemia was confirmed in 14 (61%) cases and deep organ involvement included lungs, liver, spleen, central nervous system and kidneys...

Efavirenz (EFV) is a non-nucleoside reverse transcriptase inhibitor indicated for treatment of HIV-1 infection. Despite concern over EFV tolerability in clinical trials and practice, particularly related to central nervous system (CNS) adverse events, some observational studies have shown high rates of EFV continuation at one year and low rates of CNS-related EFV substitution. The objective of this study was to further examine the real-world rate of CNS-related EFV discontinuation in antiretroviral therapy naïve HIV-1 patients...
