BACKGROUND: Residents life is more than hectic, it is hard to find place and time for training basic and advanced microsurgical skills. Surgical instruments, sutures can be purchased (or loaned from department) but the most expensive and space occupying device is microscope. In developing countries microscopes are used where the need is most; in operation rooms. Furthermore conventional microscope is not portable. For all mentioned reasons availability of microscope for training microsurgery is very limited...

The work of Jacques Derrida has received relatively little attention within nursing philosophy. Perhaps this is because Derrida is known best for deconstructing philosophy itself, a task he performed by making language unintelligible to make a point. This in itself makes his work daunting for nurses who do applied philosophy. Despite these difficulties, Derrida's focus on holding open a space for ideas, particularly those ideas that are invisible or unpopular, holds potential for enhancing the diversity of ideas within nursing...

BACKGROUND: This investigation was designed to uncover the relations between students' cognitive and metacognitive strategies used during a complex climate simulation. While cognitive strategy use during science inquiry has been studied, the factors related to this strategy use, such as concurrent metacognition, prior knowledge, and prior interest, have not been investigated in a multidimensional fashion. AIMS: This study addressed current issues in strategy research by examining not only how metacognitive, surface-level, and deep-level strategies influence performance, but also how these strategies related to each other during a contextually relevant science simulation...

Alzheimer's disease (AD) is the kind of dementia that affects the most people around the world. Therefore, an early identification supporting effective treatments is required to increase the life quality of a wide number of patients. Recently, computer-aided diagnosis tools for dementia using Magnetic Resonance Imaging scans have been successfully proposed to discriminate between patients with AD, mild cognitive impairment, and healthy controls. Most of the attention has been given to the clinical data, provided by initiatives as the ADNI, supporting reliable researches on intervention, prevention, and treatments of AD...

Understanding individual-level variation in response to the environment is fundamental to understanding life-history evolution and population dynamics. Telomeres, the protective caps at the ends of chromosomes, shorten in response to oxidative stress, and telomere shortening is correlated with reduced survival and lifespan. Investigating telomere dynamics may help us quantify individual variation in the costs experienced from social and ecological factors, and enhance our understanding of the dynamics of natural populations...

OBJECTIVE: Effective communication among providers, families, and patients is essential in critical care but is often inadequate in the PICU. To address the lack of communication education pediatric critical care medicine fellows receive, the Children's Hospital of Pittsburgh PICU developed a simulation-based communication course, Pediatric Critical Care Communication course. Pediatric critical care medicine trainees have limited prior training in communication and will have increased confidence in their communication skills after participating in the Pediatric Critical Care Communication course...

The relationship between extracellular space (ECS) diffusion parameters and brain drug clearance is not well-studied, especially in the context of Parkinson's disease (PD). Therefore, we used a rodent model of PD to explore the distribution and clearance of a magnetic resonance tracer. Forty male Sprague Dawley rats were randomized into four different groups: a PD group, a Madopar group (PD + Madopar treatment), a sham group, and a control group. All rats received an injection of the extracellular tracer gadolinium-diethylene triaminepentacetic acid (Gd-DTPA) directly into the substantia nigra (SN)...

OBJECTIVE: Unilateral analgesia often occurs with epidural analgesia. Traditional methods of troubleshooting this problem can be insufficient in obtaining adequate pain relief in a timely manner for terminal cancer patients. This case report demonstrates a safe and effective solution which can be utilized in these circumstances. CASE REPORT: A 55-year-old female with stage IV pancreatic cancer and life expectancy of a few weeks presented to the interventional pain clinic with intractable sacral pain...

Siamak Mehrkanoon, Johan A K Suykens
Domain adaptation learning is one of the fundamental research topics in pattern recognition and machine learning. This paper introduces a regularized semipaired kernel canonical correlation analysis formulation for learning a latent space for the domain adaptation problem. The optimization problem is formulated in the primal-dual least squares support vector machine setting where side information can be readily incorporated through regularization terms. The proposed model learns a joint representation of the data set across different domains by solving a generalized eigenvalue problem or linear system of equations in the dual...

Neonatal hyperbilirubinemia is generally a benign transitional phenomenon, and may even be a protective antioxidant mechanism for human neonates who may be vulnerable to the oxidative stress (compared to life in utero) encountered during birth an extra-uterine oxidative environment (1, 2). The pathophysiologic impact of neonatal unconjugated hyperbilirubinemia has been well reviewed in this supplement (see Jon fill-in). The severity of hyperbilirubinemia varies due to the magnitude of an imbalance between two major contributing processes: (i) an increase bilirubin production rate due to an increase in heme turnover (two to three times that of an adult) due to the degradation of fetal red blood cells (RBCs), which have a shortened lifespan, after birth (3, 4); and/or (ii) a diminished ability of the immature newborn liver to conjugate bilirubin and therefore excrete bilirubin in bile...

The widespread bacterial resistance to a broad range of antibiotics necessitates rapid antibiotic susceptibility testing before effective treatment could start in the clinic. Among resistant bacteria, Staphylococcus aureus is one of the most important, and Methicillin-resistant (MRSA) strains are a common cause of life threatening infections. However, standard susceptibility testing for S. aureus is time consuming and thus the start of effective antibiotic treatment is often delayed. To circumvent the limitations of current susceptibility testing systems, we designed an assay that enables measurements of bacterial growth with higher spatial and temporal resolution than standard techniques...

The aim of this study is to analyze the anatomical changes leading to the appearance of jugal aging with the appearance of jowls. It is also to describe the different techniques and to highlight those that are most effective with the permanent concern of obtaining a natural result with a well-defined jawline and a harmonious distribution of jugal volumes. For this purpose, the techniques of lifting with relocation of the displaced volumes and lipostructure are often associated with the strict respect of different directional vectors for the underlying tissues and for the skin redraping...

INTRODUCTION: Until now, estimates of the Global Burden of Disease (GBD) have mainly been produced on national or regional levels. These general estimates, however, are less useful for city governments who have to take decisions on local scales. To address this gap, we focused on the city-level burden of disease (BD) due to exposures affected by urban and transport planning. We conducted a BD assessment using the Urban and Transport Planning Health Impact Assessment (UTOPHIA) tool to estimate annual preventable morbidity and disability-adjusted life-years (DALYs) under compliance with international exposure recommendations for physical activity (PA), exposure to air pollution, noise, heat, and access to green spaces in Barcelona, Spain...

BACKGROUND: Hyperkyphosis is associated with physical impairments, activity limitations, and reduced quality of life. Therefore, a simple, reliable, responsive, and valid clinical measure of dorsal kyphosis would be valuable to clinicians. OBJECTIVE: To describe a novel procedure for measuring kyphotic curvature-the inclinometric kyphosis measure (IKM)-and provide an estimation of reliability, responsiveness, and validity. METHODS: During 2 sessions spaced days apart, we used a bubble inclinometer to measure dorsal kyphosis in 68 patients receiving outpatient physical therapy...

Sodium-ion batteries (SIBs) have caught considerable attention in last few years owing to abundant resource of sodium by comparison with lithium. The commercial graphite anode is demonstrated unsuitable as anode material for SIBs due to the larger radius of Na+ ions while the transition metal dichalcogenides (TMDs) show great potential as anode for SIBs because of their high achievable capacity. However, the sluggish kinetics, large volume expansion and aggregation of those materials result in severe decay of the electrochemical performance...

Carbapenem-hydrolyzing class D β-lactamases (CHDLs) produce resistance to the last-resort carbapenem antibiotics and render these drugs ineffective for the treatment of life-threatening infections. Here, it is shown that among the clinically important CHDLs, OXA-143 produces the highest levels of resistance to carbapenems and has the highest catalytic efficiency against these substrates. Structural data demonstrate that acylated carbapenems entirely fill the active site of CHDLs, leaving no space for water molecules, including the deacylating water...

REVIEW
Georg C Clarici
CLINICAL ISSUE: In Austria approximately 2000 people suffer from severe brain injury per year. Brain trauma is the most common cause of death under the age of 45 years. In polytrauma patients the treatment and management of severe brain injury is particularly challenging because the life-threatening injuries of other organ systems significantly influence the timing of surgery and the outcome. The sequence of the necessary surgery is an interdisciplinary decision already made in the emergency room...
