BACKGROUND: Herpes Simplex Virus (HSV) drug resistance is a significant public health concern among immunocompromised individuals. Phenotypic assays are considered the gold standard method for detecting HSV drug resistance. However, plaque reduction assays (PRAs) are technically demanding, often with long turnaround times of up to four weeks. In contrast, genotypic tests can be performed within a few days. OBJECTIVES: The development and coordination of the first European External Quality Assessment (EQA) study to evaluate phenotypic and genotypic methods used for HSV drug resistance testing in specialised reference laboratories...

Recognising structural and functional development of the paediatric foot is fundamental to ensuring a strong theoretical framework for health professionals and scientists. The transition of an infant from sitting to walking takes approximately 9 months and is when the structures and function of the foot must respond to the challenges of bearing load; becoming increasingly more essential for locomotion. Literature pertaining to the phase of development was searched. A narrative approach synthesised the information from papers written in English, with non-symptomatic infant participants up to the development stage of independent walking or two years of age...

Streptococcus suis (S. suis) is an important swine pathogen that can cause a variety of diseases. S. suis serotype 9 (SS9) is a prevalent serotype, but limited information is available. Here, we studied and compared 30 SS9 isolates, including 24 isolates from China between year 2004 and 2013, 5 isolates from Vietnam and a serotype reference isolate from Denmark. A MLST analysis was performed to exploit the genetic relationships between those isolates. The phylogenetic tree based on the MLST data divides those isolates into two clades (I and II), revealing different evolutionary paths of collected strains...

Our use of modern cardiovascular imaging tools has not kept pace with their technological development. Diagnostic errors are common but seldom investigated systematically. Rather than more impressive pictures, our main goal should be more precise tests of function which we select because their appropriate use has therapeutic implications which in turn have a beneficial impact on morbidity or mortality. We should practise analytical thinking, use checklists to avoid diagnostic pitfalls, and apply strategies that will reduce biases and avoid overdiagnosis...

Background: Blood lactate is a strong predictor of mortality, and repeated blood lactate assays are recommended during surgery in high-risk patients. We hypothesized that the use of intravascular microdialysis incorporated in a central venous catheter would be interchangeable with the reference blood gas technique to monitor changes in blood lactate. Methods: Microdialysis and central venous blood lactate measurements were recorded simultaneously in high-risk cardiac surgical patients...

PURPOSE: Increasing criticism of maintenance of certification (MOC) examinations has prompted certifying boards to explore alternative assessment formats. The purpose of this study was to examine the effect of allowing test takers to access reference material while completing their MOC Part III standardized examination. METHOD: Item response data were obtained from 546 physicians who completed a medical subspecialty MOC examination between 2013 and 2016. To investigate if accessing references was related to better performance, an analysis of covariance was conducted on the MOC examination scores with references (access or no access) as the between-groups factor and scores from the physicians' initial certification examination as a covariate...

BACKGROUND: Physicians counseling athletes on the prognosis of sport-specific performance outcomes after anterior cruciate ligament reconstruction (ACLR) depend on the published literature. However, critical appraisal of the validity and biases in these studies is required to understand how ACLR affects an athlete's ability to return to sport, the athlete's sport-specific performance, and his or her ability to achieve preinjury levels of performance. PURPOSE: This review identifies the published prognostic studies evaluating sport-specific performance outcomes after ACLR...

INTRODUCTION: In the United States, opioid regulations have become increasingly stringent in recent years. Increased regulatory scrutiny, in part, is related to heightened awareness through literature and a recent media blitz on the opioid prescription epidemic. These regulations have the potential to impact prescription trends by health care providers. Our objective was to evaluate changes in the type and dose of opioid prescriptions among patients who are referred by oncologists to an outpatient palliative care clinic...

In this paper we provide insight into an anomalous corrosion process, referred to as electro-ablation (EA), which converts multi-layer flakes of transition metal diselenides like MoSe2 into their corresponding monolayers when micromechanically exfoliated on a conductive electrode and subsequently subjected to a high anodic potential inside a conventional electrochemical cell. Photoluminescence intensity map and scanning transmission electron microscopy (STEM) images confirmed the single crystalline nature and 2H-hexagonal lattice structure of the remnant monolayer MoSe2 flakes, indicating the superior corrosion stability of the monolayers compared to the bulk counterpart...

Background: As costs of cancer care rise, the importance of documenting value in oncology increases. Proton beam radiotherapy (PBT) has the potential to reduce toxicities in cancer patients, but is relatively expensive and unproven. Evaluating quality of life (QOL) and patient-reported outcomes (PROs) is essential to establishing PBT's "value" in oncologic therapy. The goal of this systematic review was to assess QOL and PROs in patients treated with PBT. Methods: Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)-guided systematic searches were conducted...

Cyclic signals are an intrinsic part of daily life, such as human motion and heart activity. The detailed analysis of them is important for clinical applications such as pathological gait analysis and for sports applications such as performance analysis. Labeled training data for algorithms that analyze these cyclic data come at a high annotation cost due to only limited annotations available under laboratory conditions or requiring manual segmentation of the data under less restricted conditions. This paper presents a smart annotation method that reduces this cost of labeling for sensor-based data, which is applicable to data collected outside of strict laboratory conditions...

Factor XIII deficiency (FXIIID) is a rare hereditary bleeding disorder arising from heterogeneous mutations, which can lead to life-threatening hemorrhage. The diagnosis of FXIIID is challenging due to normal standard coagulation assays requiring specific FXIII assays for diagnosis, which is especially difficult in developing countries. This report presents an overview of FXIIID diagnosis and laboratory methods and suggests an algorithm to improve diagnostic efficiency and prevent missed or delayed FXIIID diagnosis...

Contents I. II. III. IV. V. VI. References SUMMARY: Savannas are highly variable systems, and predicting variation, especially in the tree layer, represents a major unresolved challenge for forecasting biosphere responses to global change. Prediction to date has focused on disentangling interactions between resource limitation and chronic disturbances to identify what determines local savanna vegetation heterogeneity. By focusing at too fine a scale, this approach overlooks: sample size limitation arising from sparse tree distributions; stochasticity in demographic and environmental processes that is preserved as heterogeneity among tree populations with slow dynamics; and spatial self-organization...

BACKGROUND: The inverted peno-scrotal flap method is considered the standard method of vaginoplasty in male-to-female genital reassignment surgery. Though with numerous advantages, the method has its limitations regarding skin texture, lack of inherent lubrication, and that the tissues for creating the labia depend on the amount of tissues remaining after vaginoplasty. Our purpose was to describe the procedure and outcome of vaginoplasty applying a new technique: autologous buccal micro-mucosa free graft combined with posterior scrotal flap transfer, which could solve some of the problems the previous methods had...
