PURPOSE: We aim to report our results in terms of chronic toxicities and cosmetic outcomes after intraoperative radiotherapy (IORT) using kV X-rays in women treated for early breast cancer at our institution. METHODS: Patients with early breast carcinoma were recruited between April 2011 and November 2014. After breast-conserving surgery, patients were treated with IORT using the Intrabeam(®) device. IORT was completed by whole-breast radiotherapy (WBRT) at a dose of 46-50...

Evidence suggests that rabies vaccine may have non-specific protective effects in animals and children. We analyzed four years of data (2012-2015) from an observational study of the health and demographics of a population of owned, free-roaming dogs in a low-income community in South Africa. The objective of this analysis was to assess the association between rabies vaccine and all-cause mortality in dogs, stratified by age group (0-3months, 4-11months, and 12months and older), and controlling for the effects of sex and number of dogs in the residence...

BACKGROUND: Population based cancer registration provides a critical role in disease surveillance in terms of incidence, survival, cancer cluster investigations and prevalence trends, and therefore high levels of completeness and timeliness are required. This study estimates completeness and variation between early and late registrations in the N. Ireland Cancer Registry (NICR) and assesses the implications for reporting cancer incidence and for registry-based research. METHODS: Two main approaches assessed completeness...

BACKGROUND: Inappropriate antimicrobial use can threaten patient safety and is the focus of collaborative physician and pharmacist antimicrobial stewardship teams. However, antimicrobial stewardship is not comprehensively taught in medical or pharmacy school curricula. Addressing this deficiency can teach an important concept as well as model interprofessional healthcare. METHODS: We created an antimicrobial stewardship curriculum consisting of an online learning module and workshop session that combined medical and pharmacy students, with faculty from both professions...

Genetic diversity in breeding programs can be impaired by fixation of alleles derived from a limited number of founder lines. This is demonstrated with the use of a solid-stem trait derived from the Portuguese landrace 'S-615' over 70 yrs ago that is widely used to resist the wheat stem sawfly ( Norton, WSS) in North America. The objective of this study was to evaluate haplotype diversity underlying the quantitative trait locus (QTL) that controls the majority of the S-615 derived solid-stem genetic variation using single-nucleotide polymorphism (SNP) assays in a diverse set of 228 solid-stem tetraploid and hexaploid wheat accessions originating from areas of the world infested with various species of WSS...

BACKGROUND: The surgical management of traumatic patellar dislocations in adolescents is associated with a lower rate of recurrent dislocations compared with nonoperative care. However, the attendant cost of surgery and the quality-of-life benefit of a surgical treatment strategy are unclear. PURPOSE: To compare the cost-utility of 3 management strategies for acute first-time patellar dislocations in adolescents: (1) nonoperative treatment only, (2) initial nonoperative treatment with surgery only for recurrent dislocations, and (3) immediate surgery...

Chlorotoxin (CTX), a disulfide-rich peptide from the scorpion Leiurus quinquestriatus, has several promising biopharmaceutical properties, including preferential affinity for certain cancer cells, high serum stability, and cell penetration. These properties underpin its potential for use as a drug design scaffold, especially for the treatment of cancer; indeed, several analogues of CTX have reached clinical trials. Here, we focus on its ability to internalize into cells - a trait associated with a privileged sub-class of peptides called cell-penetrating peptides - and whether it can be improved through conservative substitutions...

Inspired by Conan Doyle's novels, the pro contender of this Polar View undertakes an elegant exercise in territory common to epidemiology and police investigation and concludes that cyclic episodes of dehydration in individuals exposed to heavy work in very hot climates is the cause of Mesoamerican and Sri Lankan nephropathy. The contender in the opposite camp accepts the idea that dehydration may play a key role in this condition but highlights a different explanation, that it is contaminated water used for rehydration that is the eventual cause of the disease...

Objective. To design instructional methods that would promote long-term retention of knowledge of antimicrobial pharmacology, particularly the spectrum of activity for antimicrobial agents, in pharmacy students. Design. An active-learning approach was used to teach selected sessions in a required antimicrobial pharmacology course. Students were expected to review key concepts from the course reader prior to the in-class sessions. During class, brief concept reviews were followed by active-learning exercises, including a novel schematic method for learning antimicrobial spectrum of activity ("flower diagrams")...

BACKGROUND: Few data are available for the prevalence of Strongyloides stercoralis in the Caribbean region. This frequently under diagnosed soil-transmitted helminth (STH) can result in long-term low intensity chronic infections that are asymptomatic or can cause varied intestinal disturbances. With autoinfections, infections lasting over 60 years can occur and hyperinfections lead to high morbidity and mortality. METHODOLOGY/PRINCIPAL FINDINGS: Historical literature was searched to determine the prevalence of S...

Our eyes are constantly in motion, even during "steady" fixation. In ophthalmic systems equipped with wavefront technology, both eye and head motion potentially degrade its performance and/or increase the cost and complexity, as they induce a movement of the entrance optical pupil of the system. Here, we characterize the pupil motion in an aberrometry setting, using a custom, high-speed pupil tracker (478 Hz), and draw conclusions on design considerations of future ophthalmic systems. We also demonstrate the feasibility of tracking such motion directly with a custom-built Hartmann-Shack sensor (236 Hz) using a method that offers certain benefits over previously suggested approaches, thereby paving the way to an efficient and cost-effective approach...

Adaptive optics is a promising technique for the improvement of microscopy in tissues. A large palette of indirect and direct wavefront sensing methods has been proposed for in vivo imaging in experimental animal models. Application of most of these methods to complex samples suffers from either intrinsic and/or practical difficulties. Here we show a theoretically optimized wavefront correction method for inhomogeneously labeled biological samples. We demonstrate its performance at a depth of 200 μm in brain tissue within a sparsely labeled region such as the pyramidal cell layer of the hippocampus, with cells expressing GCamP6...

REVIEW
W Conan Mustain
Rectoceles are a very common finding in patients, and symptoms most commonly include pelvic pain, pressure, or difficulty with passing stool. However, there are often other associated pelvic floor disorders that accompany rectoceles, making the clinical significance of it in an individual patient often hard to determine. When evaluating a patient with a rectocele, a thorough history and physical exam must be conducted to help delineate other causes of these symptoms. Treatment consists of addressing other defecatory disorders through various methods, with surgery reserved for select cases in which obstructed defecation is well documented...

"It is a capital mistake to theorize before one has data," said Sherlock Holmes creator and author Arthur Conan Doyle in 1887. In this era of big data, and especially the crush of medical information becoming available through new technologies and bulging databases, Doyle's quote could be updated to: "It is a capital mistake to theorize before one has data and understands what they mean."

The RTS,S/AS01 malaria vaccine has been associated with meningitis and cerebral malaria safety signals. Key characteristics of the meningitis signal include presence, in the 5-17month but not the 6-12week age group, of delayed and variable meningitis onset after vaccination, and multiple etiologies. For both meningitis and cerebral malaria, the 5-17month old age group control arm had abnormally low incidences while other arms in both age groups had meningitis and cerebral malaria incidences similar to background rates...

Neutrophils are directly responsible for destroying invading pathogens via reactive oxygen species, antimicrobial peptides, and neutrophil serine proteases (NSPs). Imbalance between NSP activity and endogenous protease inhibitors is associated with chronic inflammatory disorders, and engineered inhibitors of NSPs are a potential therapeutic pathway. In this study we characterized the extended substrate specificity (P4-P1) of the NSP cathepsin G using a peptide substrate library. Substituting preferred cathepsin G substrate sequences into sunflower trypsin inhibitor-1 (SFTI-1) produced a potent cathepsin G inhibitor (Ki = 0...
