BACKGROUND: Simulation training is becoming an increasingly important component of skills acquisition in surgical specialties, including Plastic Surgery. Non-living simulation models have an established place in Plastic Surgical microsurgery training, and support the principles of replacement, reduction and refinement of animal use. A more sophisticated version of the basic chicken thigh microsurgery model has been developed to include dissection of a type 1-muscle flap and is described and validated here...

The core goal of "Thirteenth Five-Year Plan for National Eye Health (2016 to 2020)" is to obtain eye health. At present, there are still several problems hampering Chinese eye health management system development, including the lack of top policy design, system protection and financial investment, weak support from primary health care institutions, other medical disciplines and social forces, and insufficient digital information. To achieve effective eye health management, it is necessary to address the sustainability of eye health management, the integrity of eye health digital information data and the feasibility of eye health payment...

OBJECTIVE: Preventive strategies are known to reduce cancer risk and incidence and improve prognosis. Men seldom seek medical information about cancer prevention and risk reduction. The aim of this meta-narrative systematic review was to critically appraise evidence from qualitative, quantitative, and mixed-methods studies that explored men's information-seeking behaviours in relation to cancer prevention and risk reduction. METHODS: MEDLINE, CINAHL Plus with Full Text, PsycINFO, PsycARTICLES, Psychology and Behavioral Sciences Collection, Education Full Text, and ERIC were systematically searched for studies published in English between January 1(st) 2006 and May 30(th) 2016...

In a consensus process during four sessions in 2016, the working group "lower cervical spine" of the German Society for Orthopedic and Trauma Surgery (DGOU), formulated "Therapeutic Recommendations for the Lower Cervical Spine", taking into consideration the current literature. Therapeutic goals are a permanently stable, painless cervical spine and the protection against secondary neurologic damage while retaining the greatest possible amount of motion and spinal profile. Due to its ease of use and its proven good reliability, the AOSpine classification for subaxial cervical injuries should be used...

BACKGROUND: Pancreatic neuroendocrine tumors (PNETs) are rare neoplasms accounting for less than 5% of all pancreatic malignancies. These tumors are characterized by clinical and prognostical heterogeneity and are predominantly diagnosed in a metastatic stage. Cytotoxic chemotherapy, along with alkylating agents and antimetabolites as well as molecular targeted agents (everolimus, sunitinib), is used in the treatment of advanced PNETs. After the approval of lanreotide for unresectable PNETs, an additional therapeutic option has become available; however, the best sequence of therapies and patient stratification to different treatments remains challenging...

Jacqueline MacDonald Gibson, Kelsey J Pieper
BACKGROUND: Evidence suggests that the 44.5 million U.S. residents drawing their drinking water from private wells face higher risks of waterborne contaminant exposure than those served by regulated community water supplies. Among U.S. states, North Carolina (N.C.) has the second-largest population relying on private wells, making it a useful microcosm to study challenges to maintaining private-well water quality. OBJECTIVES: This paper summarizes recommendations from a two-day summit to identify options to improve drinking-water quality for N...

BACKGROUND: Vitamin D is an environmental and dietary agent with known anticarcinogenic effects, but protection against breast cancer has not been established. OBJECTIVE: We evaluated the association between baseline serum 25-hydroxyvitamin D [25(OH)D] levels, supplemental vitamin D use, and breast cancer incidence over the subsequent 5 y of follow-up. METHODS: From 2003-2009, the Sister Study enrolled 50,884 U.S. women 35-74 y old who had a sister with breast cancer but had never had breast cancer themselves...

It has long been proposed that the gait alterations associated with barefoot running are mediated by alterations in sensory feedback, yet there has been no data to support this claim. Thus, the purpose of this study was to examine the role of superficial plantar cutaneous feedback in barefoot and shod running. METHODS: 10 healthy active subjects (6 male, 4 female); mass: 65.2+9.7kg; age: 27+7.1years participated in this study. 10 over-ground running trials were completed in each of the following conditions: barefoot (BF), shod (SHOD), anesthetized barefoot (ANEST BF) and anesthetized shod (ANEST SHOD)...

Ripples are high-frequency bouts of coordinated hippocampal activity believed to be crucial for information transfer and memory formation. We used intracortical macroelectrodes to record neural activity in the human hippocampus of awake subjects undergoing surgical treatment for refractory epilepsy and distinguished two populations of ripple episodes based on their frequency spectrum. The phase-coupling of one population, slow ripples (90-110 Hz), to cortical delta oscillations was differentially modulated by cognitive task; whereas the second population, fast ripples (130-170 Hz), was not seemingly correlated to local neural activity...

Glaucoma is one of the leading causes of permanent vision loss. It is an ocular disorder caused by increased fluid pressure within the eye. The clinical methods available for the diagnosis of glaucoma require skilled supervision. They are manual, time consuming, and out of reach of common people. Hence, there is a need for an automated glaucoma diagnosis system for mass screening. In this paper, we present a novel method for an automated diagnosis of glaucoma using digital fundus images. Variational mode decomposition (VMD) method is used in an iterative manner for image decomposition...

Gamblers' thoughts have a fundamental influence on their gambling problem. Cognitive restructuring is the intervention of choice to correct those thoughts. However, certain difficulties are noted in the application of cognitive restructuring techniques and the comprehension of their guidelines. Furthermore, the increase of skill game players (e.g. poker) entering treatment creates a challenge for therapists, as these gamblers present with different thoughts than those of the gamblers usually encountered in treatment (e...

With increased interest in graphene-based sensors for biomolecules and other targets, we investigated the impact of ionic strength on the steady-state emissions from fluorescein labels on proteins adsorbing on pristine CVD (chemical vapor deposited)-graphene on a silica support. Using the model system of fluorescein-tagged fibrinogen we demonstrated that, for fluorescein tags on adsorbed fibrinogen, emission intensity was very sensitive to the salt concentration. This behavior was not seen for fluorescein-tagged fibrinogen in solution...

Studies of multisensory integration by single neurons have traditionally emphasized empirical principles that describe nonlinear interactions between inputs from two sensory modalities. We previously proposed that many of these empirical principles could be explained by a divisive normalization mechanism operating in brain regions where multisensory integration occurs. This normalization model makes a critical diagnostic prediction: a non-preferred sensory input from one modality, which activates the neuron on its own, should suppress the response to a preferred input from another modality...

Monozygotic twins with discordant karyotypes for trisomy 13 are rare. We report a case of a spontaneously conceived pregnancy who presented with first-trimester ultrasound finding of umbilical cord cyst and increased nuchal translucency in Twin A and no abnormalities in Twin B. Amniocentesis revealed 47,XY,+13 karyotype in Twin A and 46,XY karyotype in Twin B. Selective fetal reduction was performed for Twin A. Twin B was delivered at 32 weeks gestation with normal phenotype. Peripheral blood karyotype revealed 15% mosaicism for trisomy 13 and skin fibroblast revealed 46,XY karyotype...

Psychological science is increasingly diverse in the tools available for research and the questions it is able to ask. But this potential is seriously limited by a lack of diversity in study populations, in situations and contexts explored, and in the researchers themselves. The current situation is problematic and difficult to change because of niche construction processes that favor the status quo. Systems level changes are needed to support a healthy psychological science.

BACKGROUND: Continuous renal replacement therapy (CRRT) is commonly used to provide renal replacement therapy in the intensive care unit. Limited published data suggest that CRRT may lead to depletion of water-soluble vitamins and trace elements. The goal of this study was to identify the incidence of trace element and vitamin deficiencies in critically ill patients during CRRT. MATERIALS AND METHODS: This study is based on a retrospective chart review of patients who were referred to Emory University Hospital's nutrition support services and had at least 1 serum micronutrient level measured during CRRT (thiamin, pyridoxine, ascorbic acid, folate, zinc, and copper) between April 1, 2009, and June 1, 2012...

Simulation for education and training in health-care professions has been widely applied. However, its value as an assessment tool for competence is not fully known. Logistical barriers of simulation-based assessments have led some health-care organizations to utilize computer-based case simulations (CCSs) for assessment. This article provides a review of the literature on the identification of psychometrically sound, CCS instruments designed to measure decision-making competence in health-care professionals...

BACKGROUND: Findings from studies of food addiction in adults suggest those with food addiction are less successful in weight-loss interventions. Little is known about food addiction in obesity treatment-seeking adolescents; therefore, the purpose of this study was to explore the prevalence of food addiction and correlates of food addiction symptoms in obese adolescents entering an outpatient, weight management program. METHODS: Obese adolescents (n = 26) were administered the Yale Food Addiction Scale for Children (YFAS-C), measures of appetitive responsiveness, and health-related quality of life (HRQOL) before and following a 12-week, outpatient, behavioral weight management program...

Quercus (oak) species hybridize in complex patterns that have yet to be fully explored with phylogenomic data. Analyses to date have recovered reasonable divergent patterns, suggesting that the impact of introgression may not always be obvious in inferred oak phylogenies. We explore this phenomenon using RADseq data for 136 samples representing 54 oak species by conducting phylogenetic analyses designed to distinguish signals of lineage diversification and hybridization, focusing on the lobed-leaf species Quercus gambelii, Q...

In the vascular system, ageing is accompanied by the accrual of senescent cells and is associated with an increased risk of vascular disease. Endothelial cell (EC) dysfunction is a hallmark of vascular disease and is characterized by decreased angiogenic potential, reduced nitric oxide bioavailability, impaired vasodilation, increased production of ROS and enhanced inflammation. In ECs, the major producer of nitric oxide is the endothelial nitric oxide synthase (eNOS) enzyme that is encoded by the NOS3 gene...
