#1
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...

BACKGROUND: Nosocomial pneumonias are common in trauma patients and so interventions to prevent and treat nosocomial pneumonia may improve outcomes. Our prior work strongly suggests that tissue injury predisposes to infections like nosocomial pneumonia because mitochondrial debris originating from injured cells contains damage-associated molecular patterns that can reduce neutrophil (PMN) migration into the airway and diminish PMN function in response to bacterial inoculation of the airway...

P García-Muñoz, G Pliego, J A Zazo, A Bahamonde, J A Casas
This work assesses the feasibility of several advanced oxidation processes (CWPO Catalytic Wet Peroxide Oxidation), Photocatalysis and their combination (CWPO-Photoassisted process) for sulfonamide antibiotic degradation. Raw ilmenite was used as catalyst in both processes, because of the presence of iron and titanium in its structure. Despite both treatments allowed reaching a total starting antibiotic depletion working at pH0 = 3 and T0 = 30 °C within 30 min reaction time, significant differences were observed in terms of mineralization...

The dynamic distribution of a widely used antibiotic sulfamethoxazole between water, sediment and aquatic organisms (zebrafish) was studied in microcosms. Sulfamethoxazole concentrations in water were gradually reduced, while in sediment and zebrafish gradually increased, suggesting active adsorption and bioaccumulation processes occurring. The presence of sediment particles and their interactions with water reduced the bioaccumulation of sulfamethoxazole in zebrafish by 13-28%. The sediment of smaller particle size with more organic carbon content and higher surface area, adsorbed sulfamethoxazole more extensively and decreased its bioaccumulation most significantly...

Clostridium difficile infection (CDI) is facilitated by alteration of the microbiome following antibiotic administration. Antimicrobial therapy directed against the pathogen can treat CDI. Unfortunately, ∼20% of successfully treated patients will suffer recurrence. Bezlotoxumab, a human monoclonal antibody, binds to C. difficile toxin B (TcdB), reducing recurrence presumably by limiting epithelial damage and facilitating microbiome recovery.

Mycoplasma gallisepticum (M. gallisepticum) remains one of the most important diseases in poultry production. Controlling the impact of the disease is done by eradication of positive breeder flocks or by vaccination and medication. A widely used molecule in medication programs is tiamulin, a pleuromutilin antibiotic. Since recent data on the in vivo efficacy of this molecule are scarce, 2 challenge studies were conducted using a recently isolated M. gallisepticum strain belonging to the wildtype population with regard to its tiamulin and tetracycline minimum inhibitory concentration (MIC)...

Background: Fear of necrotizing enterocolitis (NEC) has perpetuated delayed initiation and slow advancement of enteral feeding in very low birth weight (VLBW) infants with inherent risks of parenteral alimentation. The objective of this study was to assess effect of early total enteral feeding (ETEF) on day of achievement of full enteral feeds, feed intolerance, NEC and sepsis. Methods: In total, 208 stable VLBW neonates (28-34 weeks) admitted during 6 month periods of three consecutive years were enrolled...

Persisters are rare phenotypic variants of regular bacterial cells that survive lethal antibiotics or stresses owing to slowing down of their metabolism. Recently, we have shown that polyamine putrescine can upregulate persister cell formation in Escherichia coli via the stimulation of rpoS expression, encoding a master regulator of general stress response. We hypothesized that rmf and yqjD, the stationary-phase genes responsible for ribosome inactivation, might be good candidates for the similar role owing to their involvement in translational arrest and the ability to be affected by polyamines...

Objectives: In Denmark, general practice is responsible for 75% of antibiotic prescribing in the primary care sector. We aimed to identify practice-related factors associated with high prescribers, including prescribers of critically important antibiotics as defined by WHO, after accounting for case mix by practice. Methods: We performed a nationwide register-based survey of antibiotic prescribing in Danish general practice from 2012 to 2013. The unit of analysis was the individual practice...

BACKGROUND: Streptococcus pneumoniae is a major cause of pneumonia, meningitis, sepsis, bacteremia, and otitis media. S. pneumoniae has developed increased resistance to multiple classes of antibiotics. STUDY DESIGN: Systematic literature review of prevalence, mechanisms, and clinical implications in S. pneumoniae resistance. AREAS OF UNCERTAINTY: Since S. pneumoniae resistance to penicillin was first reported with subsequent development of resistance to other classes of drugs, selection of appropriate antibiotic treatment is challenging...

Population structures of fecal indicator bacteria (FIB) isolated from catch basins, a constructed wetland, and feces from a beef cattle feedlot were compared over a two-year period. Enterococcus hirae accounted for 92% of the fecal isolates, whereas secondary environments were characterized by greater relative abundance of environmentally adapted species including Enterococcus casseliflavus. While enterococci densities in the catch basins and wetland were similar under wet and drought conditions, E. hirae predominated during rainy periods while E...

BACKGROUND: Heart failure is a major cause of mortality and morbidity, particularly among patients with advanced disease and no access to cardiac transplantation. LVAD implantation is not only a bridge-to-transplantation option for patients awaiting a heart donor, but is often used as bridge-to-destination therapy in patients unsuited for transplantation for various reasons. LVAD infection is considered the second-most common cause of death in patients who survive the initial 6 months on LVAD support...

BACKGROUND: Left ventricular assist device (LVAD) exit-site infections represent a major challenge in the era of modern LVADs. Infections caused by Pseudomonas are particularly difficult to treat due to limited antibiotic susceptibility. We hypothesized that keeping the LVAD exit site dry while bathing could result in reduced incidence of Pseudomonas infections. METHODS: Starting in April 2013, all patients who underwent placement of HeartMate II (HM II) LVAD were instructed not to take conventional showers and to keep the exit site dry while bathing...

Antibiotic resistance is a worldwide problem and changes are needed in the way antibiotics are used. The value of engaging children as key contributors in health care campaigns to increase the appropriate use of antibiotics has not been fully recognized. Little is known about how to design educational materials for children in order to enable them to be agents of change in their communities. Science education needs to improve the way it engages children so as to give them the tools needed to make responsible decisions on antibiotic use...

INTRODUCTION: The endovascular correction (EC) has emerged in recent years as a possible alternative to surgical revision (SR) in case of bleeding complications after peripheral bypass (PB) . The purpose of this study is to evaluate the efficacy and safety of EC compared to SR in case of bleeding complications of PB. METHODS: From January 2004 to December 2014, we have submitted 32 patients to surgery for acute bleeding in previous PB (25 venous bypass, in situ or reversed, 6 PTFE bypass and 1 composite bypass)...

AIM: Pseudomonas aeruginosa is one of the fatal biofilm forming pathogens which pose to be a problem in clinical infections, contamination of food and marine ecosystems. In this report a napthoquinone - Plumbagin has been explored for its antimicrobial (antibacterial and antibiofilm) activity against P. aeruginosa biofilm. The ability of Plumbagin to enhance the bioactivity of a known broad spectrum antibiotic was further assayed by combining the sub-MIC doses of Plumbagin with sub-MIC doses of Gentamicin against P...

Despite the ubiqitous nature of Mycobacterium avium complex (MAC) organisms in the environment, relatively few of those who are infected develop disease. Thus, some degree of susceptibility due to either underlying lung disease or immunosuppression is required. The frequency of pulmonary MAC disease is increasing in many areas, and the exact reasons are unknown. Isolation of MAC from a respiratory specimen does not necessarily mean that treatment is required, as the decision to treatment requires the synthesis of clinical, radiographic, and microbiologic information as well as a weighing of the risks and benefits for the individual patient...

Tze Liang Goh, Jason Wei, David Semple, John Collins
The use of antibiotic lock solutions as prophylaxis for catheter-associated blood stream infection (CRBSI) has been shown to be effective in previous randomized controlled trials. However, the cost-effectiveness of this approach had not been studied. In 2012, the routine gentamicin-heparin lock solution used in Auckland City Hospital was withdrawn from the market, leading to a change to heparin-only lock. This was then replaced with gentamicin-citrate lock in 2014. This situation allowed review of the CRBSI rate and financial impact of different catheter lock solutions...

The macrolactone natural product (-)-albocycline is a promising antibiotic candidate for the treatment of both methicillin resistant Staphylococcus aureus (MRSA) and vancomycin-resistant strains. Herein we report a concise total synthesis of (-)-albocycline in 14 steps from commercially available methyl (R)-3-hydroxybutyrate. Novel key steps include the highly regio- and stereoselective reactions of chiral N-sulfinyl metallodienamines (NSMDs) with aldehydes and the Davis oxaziridine, in addition to the Horner-Wadsworth-Emmons olefination of N-sulfinyl imines...
