PURPOSE: The impact of an antimicrobial stewardship initiative on time to first antibiotic dose and clinical outcomes in bacteremic patients was evaluated. METHODS: A single-center, retrospective study was conducted for adult inpatients who received antibiotics before and after implementation of a rapid administration of antimicrobials by an infectious diseases specialist (RAIDS) protocol. Patients admitted to an inpatient service from June to October 2011 (pre-RAIDS protocol) and from December 2011 to February 2012 (post-RAIDS protocol) were eligible for inclusion if (1) they were age 18 years or older, (2) their infection occurred two or more days after hospital admission, and (3) they had a blood culture growing an organism other than common skin contaminants (i...

The present study aims to investigate the numerous factors influencing Agrobacterium tumefaciens-mediated genetic transformation of Chinese cabbage (Brassica rapa ssp. pekinensis). Factors affecting transformation efficiency, such as age of explants, Agrobacterium concentration, and effect of acetosyringone, pre-cultivation, infection and co-cultivation time of Agrobacterium were examined. The pre-cultured hypocotyls from young seedlings prior to exposure to Agrobacterium showed higher shoot regeneration. The plant transformation with the modest A...

PURPOSE OF REVIEW: Central venous catheters (CVCs) have a prominent role in the diagnostic and therapy of neonates and children. Herein, we describe the multiple indications for CVC use and the different devices available for central venous access. Given the prevalent use of CVCs, healthcare systems are focused on reducing complications from their use, particularly central line-associated bloodstream infections (CLABSIs). The most up-to-date information available sheds light on best practices and future areas of investigation...

OBJECTIVE: The management of infective endocarditis (IE) may differ from international guidelines, even in reference centers. This is probably due to the fact that most recommendations are not based on hard evidence, so that the consensus obtained for the guidelines does not represent actual practices. For this reason, we aimed at evaluating this question in the particular field of antibiotic therapy. METHODS: Thirteen international centers specialized in the management of IE were selected, according to their reputation, clinical results, original research publications and quotations...

Investigators often rely on studies of Escherichia coli to characterize the burden of antibiotic resistance in a clinical or community setting. To determine if prevalence estimates for antibiotic resistance are sensitive to sample handling and interpretive criteria, we collected presumptive E. coli isolates (24 or 95 per stool sample) from a community in an urban informal settlement in Kenya. Isolates were tested for susceptibility to nine antibiotics using agar breakpoint assays and results were analyzed using generalized linear mixed models...

BACKGROUND: The rate of elective Caesarean Section (CS) is rising in many countries. Many obstetric units in the UK have either introduced or are planning to introduce enhanced recovery (ER) as a means of reducing length of stay for planned CS. However, to date there has been very little evidence produced regarding the necessary components of ER for the obstetric population. We conducted a rapid review of the composition of published ER pathways for elective CS and undertook an umbrella review of systematic reviews evaluating ER components and pathways in any surgical setting...

REVIEW
Harry Dym, Joseph Zeidan
Osteomyelitis is an inflammation of bone marrow with a tendency for progression, involving the cortical plates and often periosteal tissues, with most cases occurring after trauma to bone or bone surgery or secondary to vascular insufficiency. Antimicrobial therapy and surgical débridement are the primary modalities of osteomyelitis treatment, although often it is associated with a prolonged course, requiring a large commitment between patient and clinician as well as sizable health care costs. Despite surgical and chemotherapeutic advancements, osteomyelitis remains difficult to treat, and no universally accepted protocol for treatment exists...

The long-acting azalide antibiotic gamithromycin is marketed for intramuscular treatment of bovine and swine infections. Off-label use in foals leads to severe local lesions likely caused by hyperosmolality of the injected solution. We provide evidence from a pharmacokinetic study in 10 warm-blooded healthy foals for intravenous bolus injection of gamithromycin diluted in distilled water to be a safe and well tolerated alternative. By intravenous dosing, markedly higher plasma exposure and better penetration into bronchoalveolar lavage cells but lower distribution into epithelial lining fluid are achieved as after intramuscular or subcutaneous administration...

Antimicrobial resistance to current antibiotics is a significant public health problem and the need for new antibiotics is a compelling one. We have been developing a new series of antibiotics, propargyl-linked diaminopyrimidines, based on the structure of trimethoprim. To date we have discovered compounds that are effective inhibitors of dihydrofolate reductase (the target of trimethoprim), that are potent antibiotics in vitro against a range of Gram-positive pathogens including methicillin-resistant S. aureus, and that are non-toxic in mammalian cell culture...

Infectious pneumonia is a major cause of morbidity/mortality, mainly because of the increasing rate of microorganisms resistant to antibiotics. Photodynamic Therapy (PDT) is emerging as a promising approach, as effects are based on oxidative stress, preventing microorganism resistance. In two previous studies, the in vitro inactivation of Streptococcus pneumoniae using indocyanine green (ICG) and infrared light source was a success killing 5 log10 colony-forming units (CFU/mL) with only 10 μmol/L ICG. In this work, a proof-of-principle protocol was designed to treat lung infections by PDT using extracorporeal illumination with a 780 nm laser device and also ICG as photosensitizer...

Acute neuronal tissue preparations, brain slices and retinal wholemount, can usually only be maintained for 6 - 8 h following dissection. This limits the experimental time, and increases the number of animals that are utilized per study. This limitation specifically impacts protocols such as calcium imaging that require prolonged pre-incubation with bath-applied dyes. Exponential bacterial growth within 3 - 4 h after slicing is tightly correlated with a decrease in tissue health. This study describes a method for limiting the proliferation of bacteria in acute preparations to maintain viable neuronal tissue for prolonged periods of time (>24 h) without the need for antibiotics, sterile procedures, or tissue culture media containing growth factors...

BACKGROUND: Infection after osteosynthesis is an important complication with significant morbidity and even mortality. These infections are often caused by biofilm-producing bacteria. Treatment algorithms dictate an aggressive approach with surgical debridement and antibiotic treatment. The aim of this study is to analyze the effect of such an aggressive standardized treatment regime with implant retention for acute, existing <3 weeks, infection after osteosynthesis. METHODS: We conducted a retrospective 2-year cohort in a single, level 1 trauma center on infection occurring within 12 months following any osteosynthesis surgery...
