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...

Epidermal growth factor (EGF), a protein known for its mitogenic and anti-apoptotic effects was fed to broiler chickens to evaluate growth performance, gastrointestinal measurements, and apparent retention (AR) of components upon challenge with Eimeria. A total of 216, d old male broiler chicks (Ross 708) were placed in cages (6 birds/cage) and allocated to treatments. The treatments were: 1) control (Lactotobacilli lactis fermentation supernatant without EGF), 2) 80 μg of EGF/kg BW/d, and 3) 160 μg of EGF/kg BW/d...

As an increasingly common cause of skin infections worldwide, the prevalence of antibiotic-resistant Staphylococcus aureus (S. aureus) across China has not been well documented. This literature aims to study the resistance profile to commonly used antibiotics, including macrolides, fusidic acid (FA) and mupirocin, and its relationship to the genetic typing in 34 S. aureus strains, including 6 methicillin-resistant S. aureus (MRSA), isolated from a Chinese hospital. The MIC results showed 27 (79.4%), 1 (2.9%) and 6 (17...

BACKGROUND: Mycobacterium abscessus has been implicated as the cause of various infections in the setting of healthcare-related "outbreaks." Mandibular osteomyelitis caused by M abscessus is exceedingly rare, with only 1 patient reported in the literature. The authors describe the surgical management of 12 pediatric patients with M abscessus-related mandibular osteomyelitis and cervical lymphadenitis caused by exposure to contaminated water at a regional dental clinic. METHODS: Following institutional review board approval, new suspected patients were reviewed and followed prospectively...

Respiratory infections are the main cause of early death in patients with MECP2 duplication syndrome. We report on a 20-year-old patient with MECP2 duplication syndrome, IgG2/IgG4/IgA/IgM-deficiency and polysaccharide-specific-antibody-deficiency, who had 46 episodes of pneumonia in his first 13 years of life. Immunoglobulin substitution, daily antibiotic prophylaxis with two agents and supportive measures reduced occurrence of pneumonia to 4 episodes in the following 6 years of life.

Oral physicians frequently encounter medically compromised patients in their everyday practice and a sizable number of these patients are in urgent need of specialized care. One such medically specialized category is that of patients suffering from hydrocephalus. A large number of medical reports and citations in support of surgical care of the hydrocephalic disorder are available in literature. However, reports on dental studies offer contradictory statements on the relationship between hydrocephalic shunts and oral manoeuvres...

We have produced draft whole-genome sequences for two bacterial strains reported to produce the bulgecins as well as NRPS-derived monobactam β-lactam antibiotics. We propose reclassification of ATCC 31363 from the original Pseudomonas genus to Paraburkholderia acidophila. We further reaffirm that ATCC 31433 (Burkholderia mesoacidophila) is a taxonomically distinct producer of bulgecins with notable gene regions shared with Paraburkholderia acidophila. We use RAST multiple gene comparison and MASH distancing with published genomes to order the draft contigs and identify unique gene regions for characterization...

Tuberculosis (TB) is a chronic, potentially fatal disease caused by Mycobacterium tuberculosis (Mtb). The dihyrofolate reductase in Mtb (mt-DHFR) is believed to be an important drug target in anti-TB drug development. This enzyme contains a glycerol (GOL) binding site, which is assumed to be a useful site to improve the selectivity towards human dihyrofolate reductase (h-DHFR). There have been previous attempts to design drugs targeting the GOL binding site, but the designed compounds contain a hydrophilic group, which may prevent the compounds from crossing the cell wall of Mtb to function at the whole cell level...

Astaxanthin is a carotenoid of significant commercial value due to its superior antioxidant potential and wide applications in the aquaculture, food, cosmetic and pharmaceutical industries. A higher ratio of astaxanthin to the total carotenoids is required for efficient astaxanthin production. β-Carotene ketolase and hydroxylase play important roles in astaxanthin production. We first compared the conversion efficiency to astaxanthin in several β-carotene ketolases from Brevundimonas sp. SD212, Sphingomonas sp...

Approximately 0.5% of all births occur before the third trimester of pregnancy, and these very early deliveries result in the majority of neonatal deaths and more than 40% of infant deaths. A recent executive summary of proceedings from a joint workshop defined periviable birth as delivery occurring from 20 0/7 weeks to 25 6/7 weeks of gestation. When delivery is anticipated near the limit of viability, families and health care teams are faced with complex and ethically challenging decisions. Multiple factors have been found to be associated with short-term and long-term outcomes of periviable births in addition to gestational age at birth...

We present a rare case of cutaneous cytomegalovirus (CMV) infection in a nonimmunocompromised patient. A 74-year-old woman with a history of diabetes presented with an ulcer on the right lateral tibia that occurred at the site of a nerve core biopsy. Subsequent biopsy of the ulcer edge showed granulation tissue with neutrophilic inflammation. The patient underwent extensive antibiotic treatment for possible infection with weekly wound care. However, the ulceration persisted and enlarged. A repeat biopsy 1 year later showed superficial and deep mixed inflammation with an associated vasculitis...

Lymphomatoid papulosis (LyP) type E is a recently delineated variant characterized by the occurrence of large necrotic "eschar"-like lesions displaying microscopically angioinvasive and angiodestructive infiltrates composed of CD30 lymphocytes, frequently coexpressing CD8. In contrast to other LyP variants where patients develop multiple lesions, most patients with LyP type E present with few lesions (often 1 or 2 at a given time). In this article, we describe a 34-year-old man with LyP type E with an exacerbated clinical course characterized by the occurrence of almost a hundred of lesions...
