Published: June 2017

Purpose To analyze the accuracy of the Lambda 100 (Heine) potential visual acuity (VA) measurements in subjects undergoing cataract surgery. Methods The medical records of all consecutive patients who underwent clear corneal incision phacoemulsification cataract surgery by a single surgeon between 2010 and 2012 at the Department of Ophthalmology, Hadassah Medical Center, a tertiary care hospital in Jerusalem, Israel, were reviewed. Subjects age 18 or older with a follow-up time of at least 30 days were included. Subjects with previous ocular comorbidities other than glaucoma were excluded. In addition, patients with intraoperative or perioperative complications that could affect final VA were excluded. Analyses were performed to analyze the accuracy of preoperative retinometer potential VA as a predictor of postoperative best-corrected VA. Results A total of 374 operated eyes were included. There was a moderate positive correlation between Lambda estimated VA potential and postoperative achieved best-corrected VA (BCVA) (β coefficient 0.35, p<0.0001). Overall Lambda accurately (within 2 Snellen lines) estimated postoperative BCVA results in 60% of cases. The accuracy of prediction was significantly better in moderate cataracts when compared with advanced cataracts (p<0.01) with a twofold tendency towards underestimation in advanced cataracts. A Lambda ≥0.5 decimal has a calculated positive predictive value of 82% and a negative predictive value of 40% for predicting postoperative BCVA outcome ≥0.5 decimal. Conclusions Lambda may be used to relatively accurately predict postoperative BCVA in cataract patients, specifically in those with moderate cataracts.

Purpose To study the influence of scaffold properties on the organization of in vivo cartilage regeneration. Our hypothesis was that stress transmission to the cells seeded inside the pores of the scaffold or surrounding it, which is highly dependent on the scaffold properties, determines the differentiation of both mesenchymal cells and dedifferentiated autologous chondrocytes. Methods 4 series of porous scaffolds made of different polyacrylate polymers, previously seeded with cultured rabbit chondrocytes or without cells, were implanted in cartilage defects in rabbits. Subchondral bone was injured during the surgery to allow blood to reach the implantation site and fill the scaffold pores. Results At 3 months after implantation, excellent tissue regeneration was obtained, with a well-organized layer of hyaline-like cartilage at the condylar surface in most cases of the hydrophobic or slightly hydrophilic series. The most hydrophilic material induced the poorest regeneration. However, no statistically significant difference was observed between preseeded and non-preseeded scaffolds. All of the materials used were biocompatible, biostable polymers, so, in contrast to some other studies, our results were not perturbed by possible effects attributable to material degradation products or to the loss of scaffold mechanical properties over time due to degradation. Conclusions Cartilage regeneration depends mainly on the properties of the scaffold, such as stiffness and hydrophilicity, whereas little difference was observed between preseeded and non-preseeded scaffolds.

Published: June 2017

Purpose This study aimed to compare the diagnostic efficacies of periapical radiographs (PRs) and cone-beam computed tomography (CBCT) scans on clinicians' decision-making in diagnosing and providing treatment of fractured instruments in root canals during glide path preparation. Methods 40 maxillary molar teeth were selected and randomly divided into 4 groups. In each experimental group (n = 10), Hedstroem stainless steel instruments were fractured in mesiobuccal (MB) or distobuccal (DB) root canals. In group 1 (#0.06), group 2 (#0.08), group 3 (#0.10), and group 4 (#0.15), instruments were forced to fracture. PRs and CBCT scans were evaluated and compared. Observers were asked to use the following scoring system to decide whether to: 1. remove the fragment; 2. leave the fragment in situ; 3. bypass the fragment; or 4. use a surgical approach for removing the fragment. Results CBCT observers mostly decided on removing and bypassing the fractured fragment, while radiograph observers mostly decided to leave fragments in situ. However, there was no significant difference between these parameters when CBCT scans were compared to PRs for decision-making of the fractured instruments (p≥0.05) regarding different sizes of root canal instruments. Conclusions In decision-making regarding fractured instruments during glide path preparation, clinicians should strategize treatment options based on variables using high-resolution images that reflect accurate scenarios through PRs or CBCT scans that also take into account low radiation dosage in situ PRs have precedence for a diagnostic approach.
MUC1 rs4072037 Polymorphism is Associated with Decreased Risk of Gastric Cancer: A Meta-analysis
Authors: Ye Yu , Yang Chong , Xu Lei , Fang Dilong 
Published: June 2017

Background Several studies have recently investigated the association between mucin 1 (MUC1) rs4072037 polymorphism and gastric cancer (GC) risk, but with conflicting results. The aim of this meta-analysis was to evaluate the association between MUC1 rs4072037 polymorphism and GC risk. Methods A comprehensive database search of PubMed, Elsevier, Embase and China National Knowledge Infrastructure (CNKI) databases was performed to identify relevant studies. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were used to assess the strength of any association. Results A total of 12 papers containing 18 studies were included in this meta-analysis, involving 12,373 cases and 15,008 controls. Our data suggested that rs4072037 polymorphism was associated with a decreased risk of GC. Stratification analyses of ethnicity indicated that rs4072037 decreased the risk of GC among white populations, but no significant relationship was observed among Asian populations. No significant associations were observed in subgroups of Lauren classification (intestinal or diffuse) and anatomical classification (cardia or non-cardia). Conclusions In conclusion, this meta-analysis suggested that rs4245739 polymorphism in the MUC1 gene may play a pivotal role in the pathogenesis of GC, especially for white populations.

Published: June 2017

Aims Modified bagasse-based mesoporous carbons were prepared for the efficient chromium(III) ion adsorption and removal from aqueous solutions. Methods Mesoporous carbons were prepared from bagasse with H3PO4 activation and subsequently oxidized with nitric acid and modified with ethylenediamine. Results The results showed that the modified carbon was rich in mesopores, oxygen and nitrogen-containing groups, and the Cr(III) adsorption capacity was greatly improved after modification, which was found to be higher than both pristine and oxidized carbons. The Cr(III) adsorption capacity on modified carbon was significantly influenced by the solution pH, and the optimum pH was 6 with the maximum Cr(III) adsorption capacity up to 24.61mg/g, which was almost 3 times higher than that for pristine carbon. Thermodynamic results manifested the adsorption was spontaneous and endothermic. Kinetic rates fitted the pseudo-second-order model very well. XPS study indicated the amino group was a key factor of the high efficient adsorption.

Published: June 2017

Background This study aimed to determine the physicochemical characteristics of an eggshell-based dental abrasive material. Methods The eggshell powder abrasive material (EPAM) was synthesized by ball milling eggshell powder and surfactants. Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM) and a laser diffraction particle size analyzer (PSA) were used to characterize EPAM. In addition, the abrasive characteristics of EPAM were evaluated by comparison using poly(methyl methacrylate) (PMMA) resins. Surface roughness (Ra) was measured using a profilometer. Results The FTIR spectroscopy and XRD analysis confirmed that the carbonate product was primarily calcite (97.3%) with traces of graphite 2H (1.3%) and thenardite (1.4%). The TEM imagery revealed irregular particles in EPAM. The PSA analysis of the particle size distribution showed EPAM to be a superfine powder (0.3 μm to 50 nm). In addition, the 50-nm EPAM (Ra = 0.04 μm) measured the lowest Ra value when compared with pumice (Ra = 0.08 μm). Conclusions The salient features of this study indicate that EPAM can naturally replace calcite, which is generally mined and used as a dental abrasive material. In addition, and regarding the abrasive characteristics of EPAM in reducing the surface roughness of PMMA resin specimens, this study conclusively showed that EPAM effectively reduces the surface roughness below the threshold limit value of 0.2 μm. Potentially, EPAM could reduce waste disposal problems while enabling an economic benefit from using eggshell waste material.
Model Reference Adaptive Control Based on KP Model for Magnetically Controlled Shape Memory Alloy Actuators
Authors: Zhou Miaolei , Zhang Yannan , Ji Kun , Zhu Dong 
Published: June 2017

Introduction Magnetically controlled shape memory alloy (MSMA) actuators take advantages of their large deformation and high controllability. However, the intricate hysteresis nonlinearity often results in low positioning accuracy and slow actuator response. Methods In this paper, a modified Krasnosel'skii-Pokrovskii model was adopted to describe the complicated hysteresis phenomenon in the MSMA actuators. Adaptive recursive algorithm was employed to identify the density parameters of the adopted model. Subsequently, to further eliminate the hysteresis nonlinearity and improve the positioning accuracy, the model reference adaptive control method was proposed to optimize the model and inverse model compensation. Results The simulation experiments show that the model reference adaptive control adopted in the paper significantly improves the control precision of the actuators, with a maximum tracking error of 0.0072 mm. Conclusions The results prove that the model reference adaptive control method is efficient to eliminate hysteresis nonlinearity and achieves a higher positioning accuracy of the MSMA actuators.

Published: June 2017

Introduction Endometriosis is associated with both cyclic and non-cyclic pelvic pain. Many patients do not remain symptom free, even after guideline-oriented treatment. This study aimed to identify differences in endometriosis-associated pain and test for possible associations with hormone therapy. Methods The results presented here are based on a cross-sectional study conducted at the Charité Endometriosis Center in Berlin in which pain profile data were collected via a questionnaire from women with a confirmed diagnosis of endometriosis. The questionnaire contained items concerning cyclic and non-cyclic pain, pain intensity, and pain duration. SPSS software was used to perform the statistical analysis, including descriptive and analytical statistics. Results Of 239 women surveyed, 121 (50.6%) reported current hormone therapy, and 185 (77.4%) reported previous hormone therapy. Moreover, 84% had current (cyclic and non-cyclic) pain symptoms, which were severe enough to warrant treatment in nearly 70% of all cases. Hormone therapy was only found to be associated with a slight, non-significant advantage in patients with “cyclic pain”. The reverse was true of non-cyclic pain: women on hormone therapy reported a greater incidence of pain, greater pain intensity, more frequent need for treatment, and more pain days. Conclusions With a very broad interpretation of our findings, it can be concluded that hormone therapy achieves some degree of pain reduction via down-regulation of the ovarian cycle, at least in the case of cyclic pain, whereas non-cyclic pain does not respond or no longer responds to hormones.

Introduction Juvenile systemic sclerosis (jSSc) represents about 10% of all systemic sclerosis patients. We aim to describe the clinical characteristics and disease progression of children with jSSc followed in Portuguese pediatric rheumatology centers. Methods Clinical and laboratory features as well as medication and outcomes of jSSc children were reviewed. Results Seventeen patients were included in the analysis, 5 of whom had overlap syndromes. Thirteen girls, with a mean age at diagnosis of 10.6 ± 3.9 years and mean disease duration of 10.5 ± 3.9 years, of these 12 had diffuse cutaneous scleroderma. In 94% cases, the first symptom was Raynaud's phenomenon (RP), followed by arthritis and/or puffy hands (59%). Pulmonary involvement was documented in 7 patients at disease diagnosis, despite the paucity of respiratory complaints. Thirteen patients presented periungual capillaropathy. During follow-up, RP and skin thickening were the most frequent clinical manifestations (100%), followed by arthralgia (94%) and arthritis (76%). Pulmonary, as well as gastrointestinal involvement was documented in eight patients. Sixteen children were antinuclear (ANA) positive, eight tested positive for anti-Scl70, and one for anti-fibrillarin antibodies. Immunosuppressants (94%), proton pump inhibitors (76%) and glucocorticoids (65%) were the most common therapeutic options. One child needed autologous bone marrow transplant due to severe refractory disease. An improvement of skin thickening and stabilization of pulmonary involvement was documented in most cases. No deaths were registered in this cohort. Conclusions Raynaud's phenomenon as well as capillaroscopic abnormalities were almost universal at disease presentation. Internal organ involvement was common and occurred early during disease course, although asymptomatic in several cases.
An Accurate Full-flexion Anterolateral Portal for Needle Placement in the Knee Joint With Dry Osteoarthritis
Authors: Hussein Mohamed 
Published: June 2017

Introduction:
Accurate delivery of an injection into the intra-articular space of the knee is achieved in only two thirds of knees when using the standard anterolateral portal. The use of a modified full-flexion anterolateral portal provides a highly accurate, less painful, and more effective method for reproducible intra-articular injection without the need for ultrasonographic or fluoroscopic guidance in patients with dry osteoarthritis of the knee.

Methods:
The accuracy of needle placement was assessed in a prospective series of 140 consecutive injections in patients with symptomatic degenerative knee arthritis without clinical knee effusion. Procedural pain was determined using the Numerical Rating Scale. The accuracy rates of needle placement were confirmed with fluoroscopic imaging to document the dispersion pattern of injected contrast material.

Results:
Using the standard anterolateral portal, 52 of 70 injections were confirmed to have been placed in the intra-articular space on the first attempt (accuracy rate, 74.2%). Using the modified full-flexion anterolateral portal, 68 of 70 injections were placed in the intra-articular space on the first attempt (accuracy rate, 97.1%; P = 0.000).

Conclusion:
This study revealed that using the modified full-flexion anterolateral portal for injections into the knee joint resulted in more accurate and less painful injections than those performed by the same orthopaedic surgeon using the standard anterolateral portal. In addition, the technique offered therapeutic delivery into the joint without the need for fluoroscopic confirmation.

Fact free science plays into the hands of post-truth politics
Dijstelbloem’s view on science and truth seems to support post-truth politics. The relativistic view on science is logically inconsistent and mostly irrelevant to practical science and its contribution to society. Post truth politics should be challenged by better science and better education.

Hart, handen & voeten: de mondelinge behandeling en de pleitnota na KEI
Na invoering van KEI zal de civiele rechter in veel zaken meteen na de mondelinge behandeling uitspraak doen; alle stukken en stellingen moeten voortaan vóór de zitting zijn ingediend, en rechters worden geacht vaker instructies geven om dit te bewerkstelligen. Nieuw is deze wens niet; wel nieuw is dat de wetgever haar in de wet heeft geëxpliciteerd en op de overtreding van enkele sleutelbepalingen concretere sancties stelt. Deze bijdrage onderzoekt of de wetgever met die wijzigingen de al decennia gewenste ‘cultuuromslag’ in het civiele proces eindelijk afdwingt; praktische vraag daarbij is of partijen nog wel een pleitnota mogen indienen.
Development and Validation of a GC-MS Method for the Analysis of Homogentisic Acid in Strawberry Tree (Arbutus unedo L.) Honey
Authors: Brčić Karačonji Irena , Jurica Karlo 
Published: May 2017

Abstract
To confirm the botanical origin of strawberry tree (Arbutus unedo L.) honey, a liquid–liquid extraction followed by GC-MS method was developed for the quantitative determination of homogentisic acid (HGA), the main phenolic compound in this honey. Different parameters affecting extraction, such as the type and volume of extraction solvents, pH of the solution, and amount of salt, were optimized. The method showed good linearity (r2 = 0.9990) over the tested concentration range (50–500 mg/kg) and a low LOD (0.3 mg/kg). Precision expressed as RSD was &lt;7%. The average accuracy was 95%. The optimized method was applied for determining the HGA content in strawberry tree honey samples from Croatia. The HGA content in analyzed samples (n = 7) ranged from 245.1 to 485.9 mg/kg. The proposed method provided reliable performance and can be easily implemented for the routine monitoring of HGA in strawberry tree honey in order to assure honey QC.

ON THE HORNS OF A DILEMMA: INTELLECTUALS BETWEEN THE REGIME AND THE PEOPLE AS REFLECTED IN IRAQI COMMUNIST LITERATURE
Authors: Peled-Shapira Hilla 
Published: May 2017

This paper deals with the way in which Communist writers in mid-twentieth-century Iraq used literature in order to, on the one hand express their tense relationship with the regime during times of severe political repression, and on the other hand sharply criticize the Iraqi people themselves for not taking responsibility for or caring about their fate—or, for that matter, for failing to internalize the social class discourse to which the Communists aspired. The paper’s objective is to examine the connection between the writers’ ideology and the rhetorical and conceptual elements with which they expressed their dissatisfaction with the regime, the way Iraqi society was run, and the desires of both—intellectuals and society at large—to undergo change. In addition, this study will survey the esthetic and stylistic devices, which the writers under consideration chose, and consider both the meanings and motives behind their choices. These aspects will be examined in the framework of a proposed model of “circles of criticism.”
