PURPOSE: Multiple outcome measures exist to evaluate the outcomes of spinal decompression surgery; however, these tend to be complex and are difficult to express to the patient pre-operatively to accurately guide their expectations. We present outcomes, in terms of walking distance measurement, of a prospective single surgeon series of 76 consecutive patients with spinal stenosis. METHODS: 76 patients (mean age 68.8 years; 48-91 years) had decompression surgery using spinous process osteotomy...

The treatment of persistent infections often requires a high local drug concentration and sustained release of antimicrobial agents. This paper proposes the use of novel electrospinning of poly(lactic acid) (PLA) fibers containing uncoated and encapsulated chlorhexidine particles. Chlorhexidine particles with a mean (SD) diameter of 17.15 ± 1.99 μm were fabricated by the precipitation of chlorhexidine diacetate with calcium chloride. Layer-by-layer (LbL) encapsulation of the chlorhexidine particles was carried out to produce encapsulated particles...

In this article, we show that the underlying dimensions obtained when factor analyzing cross-sectional data actually form a mix of within-person state dimensions and between-person trait dimensions. We propose a factor analytical model that distinguishes between four independent sources of variance: common trait, unique trait, common state, and unique state. We show that by testing whether there is weak factorial invariance across the trait and state factor structures, we can tackle the fundamental question first raised by Cattell; that is, are within-person state dimensions qualitatively the same as between-person trait dimensions? Furthermore, we discuss how this model is related to other trait-state factor models, and we illustrate its use with two empirical data sets...

Many health insurance schemes include deductibles to provide consumers with cost containment incentives (CCI) and to counteract moral hazard. Policymakers are faced with choices on the implementation of a specific cost sharing design. One of the guiding principles in this decision process could be which design leads to the strongest CCI. Despite the vast amount of literature on the effects of cost sharing, the relative effects of specific cost sharing designs-e.g., a traditional deductible versus a doughnut hole-will mostly be absent for a certain context...

INTRODUCTION: The duodenum is the second most common location of intestinal diverticula following the colon (Juler et al., 1969) [1]. Only 1-5% of patients with duodenal diverticula become symptomatic (Oukachbi, 2013) [2]. The least common but most serious complication of duodenal diverticula is perforation, which has a mortality rate of 20% (Oukachbi, 2013; Yin et al., 2001; Song, 2015; Schnueriger et al., 2008) [2-5]. PRESENTATION OF CASE: A 65year old female presented with sudden onset periumbilical and epigastric pain...

Recently emerging evidence suggests that the dominant structural model of mental abilities-the Cattell-Horn-Carroll (CHC) model-may not adequately account for observed scores for mental abilities batteries, leading scholars to call into question the model's validity. Establishing the robustness of these findings is important since CHC is the foundation for several contemporary mental abilities test batteries, such as the Woodcock-Johnson III (WJ-III). Using confirmatory factor analysis, we investigated CHC's robustness across 4 archival samples of mental abilities test battery data, including the WJ-III, the Kaufman Adolescent & Adult Intelligence Test (KAIT), the Kaufman Assessment Battery for Children (KABC), and the Differential Ability Scales (DAS)...

Neural crest cells (NCCs) are highly patterned embryonic cells that migrate along stereotyped routes to give rise to a diverse array of adult tissues and cell types. Modern NCCs are thought to have evolved from migratory neural precursors with limited developmental potential and patterning. How this occurred is poorly understood. Endothelin signaling regulates several aspects of NCC development, including their migration, differentiation, and patterning. In jawed vertebrates, Endothelin signaling involves multiple functionally distinct ligands (Edns) and receptors (Ednrs) expressed in various NCC subpopulations...

INTRODUCTION: The main objective of the study was to explore the factorial structure of the French version of the Schizotypal Personality Questionnaire-Brief (SPQ-B) in a Likert format, in a representative sample of the general population. In addition, differences in the dimensional scores of schizotypy according to gender and age were analyzed. As the study in the general population of schizotypal traits and its determinants has been recently proposed as a way toward the understanding of aetiology and pathophysiology of schizophrenia, consistent self-report tools are crucial to measure psychometric schizotypy...

Nitrogen (N) management presents a sustainability dilemma: N is strongly linked to energy and food production, but excess reactive N causes environmental pollution. The N footprint is an indicator that quantifies reactive N losses to the environment from consumption and production of food and the use of energy. The average per capita N footprint (calculated using the N-Calculator methodology) of ten countries varies from 15 to 47 kg N capita(-1) year(-1). The major cause of the difference is the protein consumption rates and food production N losses...

Customary beliefs about the cause/s of AIDS are significantly related to whether or not individuals will undergo HIV testing. This study examined the cultural beliefs of construction workers in terms of their demographic and lifestyle behavioural characteristics, and their AIDS-related knowledge and stigma attitudes, to help inform improved work-based AIDS-education interventions by construction firms. A total of 512 workers drawn from 6 firms operating on 18 construction sites in the Western Cape province participated in the study...

Prior research examining cognitive ability and academic achievement relations have been based on different theoretical models, have employed both latent variables as well as observed variables, and have used a variety of analytic methods. Not surprisingly, results have been inconsistent across studies. The aims of this study were to (a) examine how relations between psychometric g, Cattell-Horn-Carroll (CHC) broad abilities, and academic achievement differ across higher-order and bifactor models; (b) examine how well various types of observed scores corresponded with latent variables; and (c) compare two types of observed scores (i...

BACKGROUND: The recent development of new neo-adjuvant treatment regimens associated with a higher success rate of down-staging has increased the interest of pancreatic surgeons on the role of extended surgery for patients affected by locally advanced pancreatic cancer. Pancreatectomy together with resection of the portal/superior mesenteric vein is considered nowadays standard of care for patients affected by pancreatic cancer. However, the resection of major abdominal arteries is still debatable...

Exploratory and confirmatory factor analytic studies were not reported in the Technical Manual for the Woodcock-Johnson, 4th ed. Cognitive (WJ IV Cognitive; Schrank, McGrew, & Mather, 2014b) Instead, the internal structure of the WJ IV Cognitive was extrapolated from analyses based on the full WJ IV test battery (Schrank, McGrew, & Mather, 2014b). Even if the veracity of extrapolating from the WJ IV full battery were accepted, there were shortcomings in the choices of analyses used and only limited information regarding those analyses was presented in the WJ IV Technical Manual (McGrew, Laforte, & Shrank, 2014)...

This work demonstrates the synthesis of new chlorhexidine polymorphs with controlled morphology and symmetry, which were used as a template for layer-by-layer (LbL) encapsulation. LbL self-assembly of oppositely charged polyelectrolytes onto the drug surface was used in the current work, as an efficient method to produce a carrier with high drug content, improved drug solubility and sustained release. Coprecipitation of the chlorhexidine polymorphs was performed using chlorhexidine diacetate and calcium chloride solutions...

The maternally inherited bacterium Wolbachia is well known for spreading in natural populations by manipulating the reproduction of its arthropod hosts, but can also have mutualist effects that increase host fitness. In mosquitoes and Drosophila some Wolbachia strains can lead to an increase in survival of virus-infected insects, and in most cases this is associated with reduced accumulation of the virus in host tissues. We investigated if the Wolbachia strain wSuz, which naturally infects Drosophila suzukii, is able to confer protection against Drosophila C virus and Flock House virus in different host genetic backgrounds...

BACKGROUND AND AIMS: Pancreaticoduodenectomy (PD) is the surgical treatment of choice for cephalopancreatic cancer representing the only hope of cure. Since its first description in 1935 by Allan Whipple, several modifications have been proposed. The execution of the Cattell-Braasch maneuver of intestinal derotation (ID) in the course of PD, by restoring the entire bowel to its embryological position, could represent a further and multiexpedient variant. MATERIALS AND METHODS: We retrospectively studied 45 consecutive pancreatic cancer patients treated with Whipple-Child PD in which the Cattell-Braasch procedure of ID was performed as integrative part of the intervention...
