Many emergency departments have implemented sepsis protocols since the 2001 publication of results from the early goal-directed therapy trial, which showed early targeted resuscitation lowers mortality. As part of an attempt to improve clinical and operational outcomes for emergency departments across British Columbia, we reviewed sepsis management literature and considered sepsis protocol implementation in the province’s emergency departments. During the literature review we found that many observational studies confirmed an association between implementation of emergency sepsis protocols and decreased mortality...

Chediak-Higashi syndrome (CHS) belongs to a group of partial oculocutaneous albinism and immunodeficiency. Five autosomal recessive conditions are recognized in this group, characterized by hypopigmentation of hair, skin and eyes, associated with recurrent infections. Additionally CHS can present coagulopathies, neurological dysfunction and large granules in many cell types. This article is protected by copyright. All rights reserved.

IL15 and IL7 are two cytokines essential for T cell development and homeostasis. In order to improve the antitumor activity by Newcastle Disease Virus (NDV)-modified tumor vaccine, we generated a recombinant NDV co-expressing IL15 and IL7 (LX/IL(15+7)) by incorporation of a 2A self-processing peptide into IL15 and IL7 using reverse genetics. B16 cells infected with LX/IL(15+7) expressed both IL15 and IL7 stably. The cytotoxicity assay showed that murine melanoma cells modified with LX/IL(15+7) could significantly enhance the antitumor immune response in vitro...

BACKGROUND: Currently, treatment of latent tuberculosis infection (LTBI) in Australia consists most commonly of a 9-month course of isoniazid (9H). A 3-month course of weekly isoniazid and rifapentine (3HP) has been shown to be as effective as 9 months of daily isoniazid, and associated with less hepatotoxicity; however, rifapentine is not currently available in Australia. Introduction of this regimen would have apparent advantages for people with LTBI in Victoria by safely shortening duration of LTBI therapy...

Healthcare-acquired infections (HAI) impact on patient care and have cost implications for the Australian healthcare system. The management of HAI is exacerbated by rising rates of antimicrobial resistance (AMR). Health-care workers and a contaminated hospital environment are increasingly implicated in the transmission and persistence of multi-resistant organisms (MRO), as well as other pathogens, such as Clostridium difficile. This has resulted in a timely focus on a range of HAI prevention actions. Core components include antimicrobial stewardship, to reduce overuse and ensure evidence-based antimicrobial use; infection prevention strategies, to control MRO - particularly methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus spp...

Salmonid alphaviruses (SAV) severely infects farmed salmonids and rainbow trout. Owing to the recent increase in fish import trade, several SAV-unreported countries, such as China, may face serious threat of this infection. Thus, it is necessary to develop efficient detection methods for the prevention and diagnosis of SAV infection. In this study, we selected a conserved segment of the SAV E1 protein as a target immunogen for the preparation of monoclonal antibodies (mAbs) specific to SAV. A sensitive indirect immunofluorescence (IF) method was developed using 26E9C2 mAb that detected E1 protein and identified subtypes 1, 2 and 5 of SAV...

An immunocompromised patient had positive blood cultures for Mycobacterium intracellulare and no identifiable organ seeding was started on treatment. One month later, the patient was clinically well with negative blood cultures but drug-induced myelotoxicity had developed. Ocular fundus examination at this time revealed bilateral choroidal granulomas which changed patient management.

A new begomovirus species was identified from tomato plants with upward leaf curling and purple vein symptoms, which was first identified in the Piaui state of Northeast (NE) Brazil in 2014. Tomato leaf samples were collected in 2014 and 2016, and PCR with degenerate primers revealed begomovirus infection. Rolling circle amplification and restriction enzyme digestion indicated a single genomic DNA of ~ 2.6 kb. Cloning and sequencing revealed a genome organization similar to DNA-A components of New World (NW) bipartite begomoviruses, with no DNA-B...

Bovine leukemia virus (BLV) is a member of the genus Deltaretrovirus of the family Retroviridae and cause a chronic lymphosarcoma, which is extensive in cattle. In yaks (Bos grunniens), the distribution, strains and genetic characteristics of BLV have rarely been studied. The aim of our study was to investigate BLV infections in domestic yaks and determine the genetic variability of BLV circulating in a region of the Qinghai Tibet Plateau, China. Blood samples were collected from 798 yaks, which were from different farms from Gansu, Qinghai and Sichuan provinces surrounding the Qinghai-Tibet Plateau...

Ornamental perennial plants may serve as reservoirs for viruses that infect field crops. Duranta repens is an ornamental shrub that frequently exhibits leaf curl symptoms typical of begomoviral infection. Two begomoviruses or DNA-A components (isolates 57SA and 58SA) along with a DNA-B component (31SA) were identified in a symptomatic D. repens plant. Isolates 57SA and 58SA showed the highest nucleotide sequence identity of 90% and 92.2% to catharanthus yellow mosaic virus (CaYMV) and chilli leaf curl India virus (ChiLCINV), respectively, whereas 31SA shared the highest nucleotide sequence identity of 95...

BACKGROUND: Spontaneous cervical artery dissections (sCAD) are often preceded by infections. However, existing data about inflammatory parameters remained inconsistent. Remarkably, concurrent information about the coagulation system, whose affection seems also reasonable to cause ischaemic events, are still lacking in sCAD patients. Thus, this study explores the association between the inflammatory and coagulation system in patients with sCAD. METHODS: The parameters leukocyte and thrombocyte count, C-reactive protein, fibrinogen, D-dimer, activated partial thromboplastin time (aPTT) and prothrombin time were extracted from hospital-based medical records of patients (n = 60) with sCAD and compared with those of a control group (n = 97) from a prospective observational stroke study...

PURPOSE: The aim of this study was to conduct a re-evaluation of current strategies for peri-operative prophylaxis of infections in orthopaedic surgery of geriatric patients (≥65 years) with proximal femoral fractures (PFF). METHODS: Between 01/2010 and 08/2014 all post-operative infections after stabilization of PFF of 1,089 geriatric patients were recorded retrospectively. All patients pre-operatively received a single dose of 1.5 g cefuroxime (group 1). These were compared to prospectively determined post-operative rates of surgical site infection (SSI) of 441 geriatric patients, which were operated on between 09/2014 and 03/2017 due to PFF...

Accurate measurement of antiretroviral therapy (ART) adherence remains challenging and there are few data assessing the validity of self-reported adherence among perinatally HIV-infected adolescents. We examined adolescent and caregiver reports of adolescent adherence among perinatally-infected adolescents aged 9-14 years in Cape Town, South Africa, and explored factors that may modify associations between reported adherence and elevated viral load (VL). Among 474 adolescents (median age 12.0 years; median duration of ART use 7...

Emily Wenande, Andrés Már Erlendsson, Merete Haedersdal
Fractional laser-assisted drug delivery (LADD) is increasingly finding its way into clinical practice as a new means to enhance topical drug uptake and improve treatment of cutaneous disorders. To date, LADD has been used for a wide range of conditions, including photodamaged skin, neoplastic lesions, scars, cutaneous infections, and vitiligo as well as for topical anesthetic and aesthetic procedures. Substantiated by randomized controlled clinical trials, strong evidence is available for LADD's usefulness for photodynamic therapy (PDT), for which improved efficacy using laser-assisted photosensitizer treatment is established for actinic keratosis compared with conventional PDT...

Sara Hogan, Mara Weinstein Velez, Omer Ibrahim
Microneedling is a minimally invasive procedure wherein small holes are created across the stratum corneum while keeping the epidermis partially intact. This produces microchannels that increase skin permeability and simultaneously stimulate growth factor release. Since the epidermis is retained, microneedling has less risk of infection, postinflammatory hyperpigmentation, and scarring compared to other resurfacing modalities. This is a review of the literature on microneedling in the treatment of textural abnormalities, specifically rhytides, scars, and striae...

OBJECTIVES: Trichomoniasis, caused by Trichomonas vaginalis (TV), is the most common curable sexually transmitted infection worldwide. Current guidance in the UK is to treat TV with a nitroimidazole antibiotic. The high prevalence of TV, high rate of antibiotic resistance and limited tolerability to nitroimidazoles suggest that alternative treatment regimens are needed. Intravaginal boric acid (BA) has been used safely for the treatment of candida vulvovaginitis and bacterial vaginosis, and in vitro studies suggest BA is active against TV...

Genome-wide association studies are widely used to identify "disease genes" conferring resistance/susceptibility to infectious diseases. Using a combination of mathematical models and simulations we demonstrate that genetic interactions between hosts and parasites (GxG interactions) can drastically affect the results of these association scans and hamper our ability to detect genetic variation in susceptibility. When hosts and parasites coevolve, these GxG interactions often make Genome-wide association studies unrepeatable over time or across host populations...
