Published: May 2019

Abstract

Objective
The aim of this study was to summarize the current evidence to evaluate the effects of laparoscopic radical nephrectomy (LRN) and open radical nephrectomy (ORN) in the treatment of renal cell carcinoma.

Methods
A comprehensive literature search was performed using PubMed, Embase and Google Scholar to identify all relevant studies. 8 published studies were included in this meta-analysis. We pooled the odds ratios (OR), standardised mean difference (SMD) and conducted heterogeneity, and quality assessment.

Results
The outcome of treatment effects included surgical blood loss, surgical time, postoperative complications, and post-operative length of hospital stay. Comparing open radical nephrectomy for kidney cancer patients, the pooled SMD of surgical time was 0.47, (95% confidential index CI = [0.09, 0.85]), the pooled SMD of operative blood loss was -68.98, (95% CI = [-99.63, -38.34]), the pooled SMD of post-operative length of hospital stay was -4.32, (95% CI = [-4.62, -4.03]), and the pooled OR of postoperative complications was 0.52, (95% CI = [0.30, 0.91]).

Conclusion
LRN was found to significantly decrease patients’ blood loss. In addition, LRN offers less post-operative length of hospital stay.

Published: May 2019

AbstractWe developed a surfactant-free spray coating process to coat commercial cellulose-based paper with carbon nanotubes (CNTs) and prepared paper-CNTs current collectors for Li-ion batteries (LIBs). The paper-CNTs were used as current collectors for replacing conventional aluminum foil. Li-ion batteries assembled using paper-CNTs were coated with LiFePO4as the active material and used as cathodes with Li as the anode, and the assembled LIBs showed a high energy density of 460 Wh kg−1at a power density of 250 W kg−1. These electrodes were stable even at a current density as high as 600 mA g−1, and showed cycling stability for ~450 cycles at 150 mAh g−1. Furthermore, paper-CNTs based electrodes showed ~17% improvement in areal capacity compared to commercial aluminum-based electrodes suggesting that paper-CNTs can readily displace Al foils as current collectors.Summary: Paper based current collectors have been proposed as a cost-effective and simple replacement for aluminum current collectors. This has been achieved by a scalable spray coating of CNTs on printing papers without any surfactants or binders and subsequently testing them as current collectors for Li-ion batteries.
Insight into the working wavelength of hotspot effects generated by popular nanostructures

Published: May 2019

Abstract
A proper excitation wavelength is much important for the application of surface-enhanced Raman spectroscopy (SERS) in the biochemical field. Here, based on a SERS substrate model with an incident Gaussian beam, we investigate the dependence of the electric field enhancement on the incident wavelength of the excitation laser for popular nanostructures, including nanosphere dimer, nanorod dimer, and nanorod arrays. The results in the present manuscript indicate that both the nanosphere and nanorod dimer present a much broader plasmonic excitation wavelength range extending to the near-infrared region. The enhancement effect of Nanorod arrays is strongly dependent on the incident direction of excitation light. Finally, according to the conclusions above, a SERS substrate consisting of nanocubes based on the SPP eigen-mode is proposed and the electric field enhancement is homogeneous, and insensitive to the polarization of the incident laser. The enhancement factor is not ultrahigh; however, good homogeneousness permits for quantitative detection of lower concentration components in mixtures.

Mechanical contribution of vascular smooth muscle cells in the tunica media of artery
Authors: Mozafari Hozhabr , Zhou Changchun , Gu Linxia 
Published: May 2019

AbstractThe stiffness of arterial wall in response to cardiovascular diseases has been associated with the changes in extracellular matrix (ECM) proteins,i.e., collagen and elastin. Vascular smooth muscle cells (VSMCs) helped to regulate the ECM reorganizations and thus contributed to arterial stiffness. This article reviewed experimental and computational studies for quantifying the roles of ECM proteins and VSMCs in mechanical properties of arteries, including nanostructure and mechanical properties of VSMCs and ECMs, cell-ECM interaction, and biomimetic gels/scaffolds induced contractile properties and phenotype changing of VSMCs. This work will facilitate our understanding of how the microenvironments and mechanotransduction impact and regulate the arterial adaptation.
Investigating the impact of dissolved natural gas on the flow characteristics of multicomponent fluid in pipelines
Authors: Ismayilov Gafar G. , Fataliyev Vugar M. , Iskenderov Elman Kh. 
Published: May 2019

Abstract
The conventional equations for describing the flow characteristics of the mixtures merely consider fluid that is homogenic, if it is above the bubble point conditions but ignore that a system containing sub-micron sized gas or vapor bubbles distributed throughout the volume of the liquid, which can exhibit unexpected heterogenic and complex phase properties. In this paper, a new mathematical model for the flowing gas-liquid mixture is presented, which has been proposed considering the colloidal feature of the system above the saturation or bubble point pressure. This approach is more in line with the actual dynamic performance of the oil and gas mixture export pipeline. Experimental data, simulations and field case studies validate the new proposed mathematical model of flow characteristics in pipeline. The obtained results confirmed that the calculated data are in good agreement with the experimental data. Based on Azerbaijan oil-gas-condensate field “Guneshli” data, this new model was used for calculating the condition in which the transformation of the flow characteristics from stable into instable is occurred. It has been discovered that the flow becomes unstable at a pressure about 30% higher than Bubble Point Pressure, which causes pulsation effect in the pipeline structure. However, homogenic behavior should be observed in this hydrodynamic condition. Also, the model provides a guideline on how to optimize the flow rate by adjusting the pipeline parameters to minimize the flow resistance, liquid slugging and hydraulic hammering effects, which cause instable operation.
From dative to accusative. An ongoing syntactic change in Romance
Authors: Pineda Anna 
Published: May 2019

AbstractIn several Romance languages, including Catalan, Spanish, Asturian and Neapolitan, several verbs (‘phone’, ‘answer’, ‘shoot’, ‘rob’, among others) can take a dative- or accusative-marked complement. I argue that this alternation is indeed a transition from dative to accusative; that is, it is a process of syntactic change, with different stages of evolution depending on the dialectal or even idiolectal variety. The relevant verbs, beinga prioridative-taking intransitive verbs, are analyzed as unergatives, made up of a light verb and a nominal, ‘phone= do+phone call’. When the complement ‘to somebody’ is added, a ditransitive structure is obtained, where I assume that the direct (‘phone call’) and the indirect (‘to somebody’) objects are related via an applicative head. The properties of this functional applicative head allow me to explain the change from dative to accusative case in the first stages of syntactic change. Likewise, I show that the completion of the syntactic change results in a true transitivization of the structure.
Phases, labeling, antilocality and intonational phrases: recomplementation in Spanish
Authors: Vera Gabriel Martínez 
Published: May 2019

AbstractThis paper addresses recomplementation (i.e. double-complementizer constructions) in Spanish, comparing Latin American Spanish (LAS) and European Spanish (ES). I make the novel observation that in spite of a superficial difference whereby a lowerqueafter a left dislocate (LD) surfaces in ES but not in LAS, LAS does have recomplementation. In fact, LAS patterns with ES in that there are two constructions in each variety, i.e. a construction in which an intonational break following the LD is present and a construction in which the break is absent. I argue that the constructions with the break differ from the constructions without it with regard to reconstruction effects,noinsertion and the position of high adverbs, which arise due to a locality violation in the former but not in the latter. I propose a syntactic analysis in terms of phases and argue that the locality violation is circumvented in the constructions with no break via verb movement, which is not possible in the constructions with the break. I further propose a mapping from the syntactic structures of recomplementation into prosody that correlates with the presence/absence of the intonational break in these constructions, hence providing prosodic evidence for phasal structure more generally.

Published: May 2019

Background and aimsUnregulated Internet pornography (IP) use is discussed as a clinically significant disorder. Because of its primarily rewarding nature, IP is a predestinated target for addictive behaviors. However, not every user develops an unregulated usage pattern. In fact, most users tend to use IP recreationally. Impulsivity-related constructs have been identified as promoters of addictive behaviors. It is unclear whether these impulsivity-related constructs are specific for unregulated IP use or also play a role in recreational but frequent behaviors. In this study, we investigated impulsive tendencies (trait impulsivity, delay discounting, and cognitive style), craving toward IP, attitude regarding IP, and coping styles in individuals with recreational–occasional, recreational–frequent, and unregulated IP use.MethodsA total of 1,498 heterosexual males participated in an online survey. Groups of individuals with recreational–occasional use (n = 333), recreational–frequent use (n = 394), and unregulated use (n = 225) of IP were identified by screening instruments.ResultsCraving and attitude regarding IP as well as delay discounting and cognitive and coping styles differed between groups. Individuals with unregulated use showed the highest scores for craving, attentional impulsivity, delay discounting, and dysfunctional coping, and lowest scores for functional coping and need for cognition. Recreational–frequent users had the most positive attitude toward IP. Motor and non-planning impulsivity did not differ between groups.Discussion and conclusionsThe results indicate that some facets of impulsivity and related factors such as craving and a more negative attitude are specific for unregulated IP users. The results are also consistent with models on specific Internet use disorders and addictive behaviors.

Published: May 2019

Background and aimsSocial media use has become increasingly popular among Internet users. Given the widespread use of social media on smartphones, there is an increasing need for research examining the impact of the use of such technologies on sexual relationships and their constructs such as intimacy, satisfaction, and sexual function. However, little is known about the underlying mechanism why social media addiction impacts on sexual distress. This study investigated whether two constructs (intimacy and perceived social support) were mediators in the association of social media addiction and sexual distress among married women.MethodsA prospective study was conducted where all participants (N = 938; mean age = 36.5 years) completed the Bergen Social Media Addiction Scale to assess social media addiction, the Female Sexual Distress Scale – Revised to assess sexual distress, the Unidimensional Relationship Closeness Scale to assess intimacy, and the Multidimensional Scale of Perceived Social Support to assess perceived social support.ResultsThe results showed that social media addiction had direct and indirect (via intimacy and perceived social support) effects on sexual function and sexual distress.Discussion and conclusionsThe findings of this study facilitate a better understanding of how problematic engaging to social media can affect couples’ intimacy, perceived social support, and constructs of sexual function. Consequently, sexual counseling should be considered an essential element for assessing individual behaviors in the context of social media use.

Abstract: Introduction: Aneurysm of the extracranial carotid artery is a rare condition and there is a diversity in the etiology. The proper treatment could be a real challenge for the surgeons. Aim: Analysis of perioperative and long term results of invasive treatment for carotid artery aneurysm. Method: A retrospective review was conducted of patients who had open or endovascular surgery due to carotid artery aneurysm through the last 13 years at the Department of Vascular Surgery of the Semmelweis University and at the Department of Surgery of the University of Szeged. Medical history, characteristics of the aneurysms, therapy and the follow-up results were reviewed. Results: Over the study period, 25 interventions were performed due to carotid artery aneurysm. There were 10 men and 15 women with a mean age of 57.8 ± 15.15 years. Seventeen patients (68%) were symptomatic. The mean aneurysm diameter was 26.8 ± 11.25 mm. The underlying etiology was atherosclerosis in eleven (44%), prior carotid endarterectomy in four (16%), infection in four (16%) and other cause (connective tissue disease, dissection, trauma) in six (24%) cases. Nineteen patients underwent open surgery, six underwent endovascular treatment. Death within 30 days was documented in one (4%) case. The mean postoperative hospital stay was 4.52 ± 2.38 days. Three (12%) patients required reintervention postoperatively. Peripheral nerve injuries were detected in four (16%) patients, all after open surgery. No stroke was documented within 30 days. The mean follow-up was 41.2 ± 38.54 months. Five (24%) deaths were not related to the carotid artery disease. One patient had stroke, one had transient ischaemic attack (TIA), and in two cases asymptomatic internal carotid artery occlusion was described. Conclusion: Both open surgery and endovascular intervention can be safely applied in the treatment of carotid artery aneurysm. Considering the variable etiology and rarity, we recommend to perform the interventions in vascular surgery centres. Orv Hetil. 2019; 160(21): 815–821.

Abstract: Introduction: Congenital sensorineural hearing loss is one of the most common sensory defects affecting 1–3 children per 1000 newborns. There are a lot of causes which result in congenital hearing loss, the most common is the genetic origin, but infection, cochlear malformation or other acquired causes can be reasons as well. Aim: The aim of this study was to establish the etiological factors of congenital profound sensorineural hearing loss in children who underwent cochlear implantation. Results: Our results show that the origin of the hearing loss was discovered in 62.9% of our patients. The most common etiological factor was the c.35delG mutation of the gap junction protein β-2 gene, the allele frequency was 38.7% in our cohort. Infection constituted to 10.1%, and meningitis and cytomegalovirus infection were the second most common cause. 79.9% of our patients received sufficient hearing rehabilitation before the end of the speech development’s period (6 years old), but 11.2% of our cases were still diagnosed late. Conclusions: Based on our data we can state that genetic evaluation is crucial in the diagnostic process of congenital profound sensorineural hearing loss. Sufficient hearing rehabilitation affects the whole life of the child, and by late cochlear implantation the speech development falls behind. We can decrease the ratio of the late implantation with the new protocol of newborn hearing screening, and with sufficient information provided to the colleagues, so the children may be referred to the proper center for rehabilitation without delay.

Abstract: Diabetes and depression are considered global epidemics. Both have multifactorial aetiologies, including external, environmental factors and internal factors in connection with physiological processes as well as genetic variants triggering disease onset. Although the co-occurrence of diabetes and depression is well described, the mechanisms underlying these diseases and their interactions are still not entirely revealed. The authors aimed to present known and potential explanations of the co-occurrence of these diseases and to highlight the importance of their timely diagnosis and effective treatment, as their co-occurrence may increase morbidity and mortality. Screening for depression among diabetes patients and for diabetes among patients with depression may decrease the incidence of complications and consequences of this comorbidity and may foster more effective treatment. General practitioners play a key role in the care of both diseases by providing timely diagnosis and adequate treatment potentially leading to a better quality of life, slower disease progression and decreased risk of complications.

Abstract: Introduction: From 2015, medical education has introduced a cost-reimbursement for medical students who do not reach the yearly rising weighted average. Aim: The authors examine the dropout behaviour of Hungarian medical students. Method: Analysis of the Higher Education Information System based on the database of those who started their medical studies in 2010 (n = 1046). Results: Early retardation of credit accumulation, the use of passive semesters are typical for dropouts. 83.6% of those who started their studies studied in state-funded education, with 9.4% dropouts among them, 50% among cost-reimbursement students. Multivariate analysis revealed the factors affecting dropout. Conclusion: The chances of dropping out are increased by the low credit number, the number of passive semesters, the cost-reimbursement financing form. A dormitory residence is safety net, the student can make social capital that can support the success of his studies. Orv Hetil. 2019; 160(21): 829–834.
