David Sweet, Julian Marsden, Kendall Ho, Christina Krause, James A Russell
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...

AIMS: To define patterns of brain injury and associated neurodevelopmental outcomes in infants with severe neonatal anaemia. METHODS: We studied 20 infants with severe anaemia at birth (haemoglobin<7g/dL). Clinical details were analysed for causes of anaemia and co-morbidities. All had early brain magnetic resonance imaging (MRI) scans, which were reviewed for injury pattern. Neurodevelopmental outcomes were assessed at a median age of 24months. RESULTS: The aetiology of the anaemia was feto-maternal haemorrhage in 17 and antepartum haemorrhage in 3 infants...

We wish to add to the recent article by Ramley et al(1) our experience on 8 cases of viral warts and one case of seborrheic keratosis (SK) on tattoos. Those cases were collected with the help of dermatologists and family doctors between 2007 and 2016. We reviewed the demographic data, delay of onset after tattooing, clinical presentation and outcomes whenever possible. The number of lesions was counted manually from the available pictures.

Cutaneous beta-papillomaviruses are associated with non-melanoma skin cancers that arise in patients who suffer from a rare genetic disorder, Epidermodysplasia verruciformis (EV) or after immunosuppression following organ transplantation. Recent studies have shown that the E6 proteins of the cancer associated beta human papillomavirus (HPV) 5 and HPV8 inhibit NOTCH and TGF-β signaling. However, it is unclear whether disruption of these pathways may contribute to cutaneous HPV pathogenesis and carcinogenesis...

: Diabetic non-healing wounds are a major clinical problem. The mechanisms leading to poor wound healing in diabetes are multifactorial but unresolved inflammation may be a major contributing factor. The complement system (CS) is the most potent inflammatory cascade in humans and contributes to poor wound healing in animal models. Signal transducer and activator of transcription 4 (STAT4) is a transcription factor expressed in immune and adipose cells and contributes to upregulation of some inflammatory chemokines and cytokines...

Mucorales are an emerging group of human pathogens that are responsible for the lethal disease mucormycosis. Unfortunately, functional studies on the genetic factors behind the virulence of these organisms are hampered by their limited genetic tractability, since they are reluctant to classical genetic tools like transposable elements or gene mapping. Here, we describe an RNAi-based functional genomic platform that allows the identification of new virulence factors through a forward genetic approach firstly described in Mucorales...

Verticillium wilt is a soil-borne disease, and severely limits the development of cotton production. To investigate the role of endophytic fungi on Verticillium wilt, CEF-818 (Penicillium simplicissimum), CEF-714 (Leptosphaeria sp.), CEF-642 (Talaromyces flavus.) and CEF-193 (Acremonium sp.) isolated from cotton roots were used to assess their effects against cotton wilt disease caused by a defoliating V. dahliae strain Vd080. In the greenhouse, all treatments significantly reduced disease incidence and disease index, with the control efficacy ranging from 26% (CEF-642) to 67% (CEF-818) at 25 days (d) after inoculation...

BACKGROUND: Laboratory testing is roughly divided into three phases: a pre-analytical phase, an analytical phase and a post-analytical phase. Most analytical errors have been attributed to the analytical phase. However, recent studies have shown that up to 70% of analytical errors reflect the pre-analytical phase. The pre-analytical phase comprises all processes from the time a laboratory request is made by a physician until the specimen is analyzed at the lab. Generally, the pre-analytical phase includes patient preparation, specimen transportation, specimen collection and storage...

Nbs1 is one of the genes responsible for Nijmegen breakage syndrome, which is marked with high radiosensitivity. In human NBS1 (hNBS1), Q185E polymorphism is known as the factor to cancer risks, although its DSB repair defect has not been addressed. Here we investigated the genetic variations in medaka (Oryzias latipes) wild populations, and found 40 nonsynonymous single nucleotide polymorphisms (SNPs) in medaka nbs1 (olnbs1) gene within 5 inbred strains. A mutation to histidine in Q170 residue in olNbs1, which corresponds to Q185 residue of hNBS1, was widely distributed in the closed colonies derived from the eastern Korean population of medaka...

To preserve genome integrity, the S-phase checkpoint senses damaged DNA or nucleotide depletion and when necessary, arrests replication progression and delays cell division. Previous studies, based on two pol2 mutants have suggested the involvement of DNA polymerase epsilon (Pol ε) in sensing DNA replication accuracy in Saccharomyces cerevisiae. Here we have studied the involvement of Pol ε in sensing proper progression of DNA replication, using a mutant in DPB2, the gene coding for a non-catalytic subunit of Pol ε...

BACKGROUND: The American College of Surgeons Committee on Trauma devised process audit filters to identify opportunities for improvement (OFI), prevent adverse outcomes, and improve quality. Delay to the operating room for primary trauma laparotomy is a process audit filter that has not been definitively associated with improved outcomes. We sought to evaluate the effectiveness of delay to the operating room of greater than 2 hours (DOR) to independently identify an adverse outcome or an OFI at our Level I trauma center...

PURPOSE OF REVIEW: To summarize the recent evidence on the treatment of abdominal sepsis with a specific emphasis on the surgical treatment. RECENT FINDINGS: A multitude of surgical approaches towards abdominal sepsis are practised. Recent evidence shows that immediate closure of the abdomen has a better outcome. A short course of antibiotics has a similar effect as a long course of antibiotics in patients with intra-abdominal infection without severe sepsis. SUMMARY: Management of abdominal sepsis requires a multidisciplinary approach...

BACKGROUND: Guatemala exhibits the sixth highest rate of child stunting worldwide, and stunting disproportionately affects Guatemala indigenous communities. In a country struggling to combat this result of malnutrition, early child nutrition is especially critical. Specifically, early initiation of breastfeeding is important for the development of newborn infants. Understanding beliefs and practices related to early initiation of breastfeeding in Maya Guatemala may provide an avenue to guide nutrition interventions in indigenous communities...

An alternative to coronary sinus implantation for a left ventricular pacing lead is frequently needed for cardiac resynchronization therapy. We have developed a transapical approach to implant an endocardial pacing lead that will reach the most delayed segment of the left ventricle. This method is easily combined with other transapical heart surgeries. After some technological improvement our technique should offer easier access and better results than other currently available implantation methods.
