Review of the article “Laparoscopic single port radical nephrectomy challenges: a case presentation”

Радикальная нефрэктомия продолжает оставаться «золотым стандартом» лечения злокачественных новообразований почки больших размеров [1]. Многими исследованиями показаны одинаковые онкологические результаты лапароскопических операций с открытыми вмешательствами, при гораздо лучшем косметическом эффекте и меньшем количестве осложнений [2]. В течение трех десятилетий, прошедших после выполнения Ральфом Клейманом первой лапароскопической радикальной нефрэктомии [3], продолжались поиски наименее инвазивных и наиболее эффективных методов этой эндоскопической операции. Ряд исследований посвящен сравнительнению трансперитонеального и ретроперитонеального доступа, оценке методик hand-assistance, NOTES и даже роботической нефрэктомии [4].Разработка целого ряда специальных эндоскопических инструментов и портов для их введения привели к концу первой декады двухтысячных к достаточно бурному развитию, так называемой, однопортовой (single‑port) хирургии [5]. Наша клиника, как и многие коллеги, тоже активно внедряли в этот период однопортовые операции, включая нефрэктомию. Поэтому я не только хорошо понимаю трудности, которые подробно описывают авторы при выполнении основных этапов операции, но и пути их разрешения, такие как перемещение камеры между портами или смена оптики с другим углом зрения. Кроме того, возможно дополнительно использовать отдельный 3-5 мм порт [6], что, впрочем, делает вмешательство «не совсем однопортовым».

Polyaniline Nanocomposites

Polyaniline in various forms has been widely explored as an electrode material for supercapacitors due to its high theoretical charge storage capacity, facile-cost-effective synthesis, good mechanical strength and ultrafast charge transport. However, commercialization of such pristine forms is very much restricted by low solubilities, rapid agglomeration during device design accompanied by poor electrochemical life and fast environmental decomposition. The blending with nano-carbon materials, metal oxides and other competent materials, may result in high quality materials– “nanocomposites” with superior features is ideally fit for future generation energy storage devices. The present chapter deals with detailed discussions on designing, the fabrication of such binary and ternary nanocomposites, correlating their morphology with electrochemical behavior, so as to optimize their supercapacitive performances. Such an attempt would help to outline the present status and future aspects of these materials which will be of first-hand assistance especially to the beginners to this field of research.

A multiple-method review of accommodations to gross motor assessments commonly used with children and adolescents on the autism spectrum

The purpose of this study is to understand the common accommodations used during standardized motor assessment of children on the autism spectrum. This study was completed in three parts: (1) a narrative review of the literature; (2) an open-ended survey sent to the first authors of the identified articles; and (3) a descriptive analysis of responses. Results revealed that 56.7% of the identified articles did not report enough information of assessment procedures, 18.9% followed the assessment manual, 16.9% provided accommodations on a needs basis, and 7.5% used a consistent modified protocol. Individual responses showed that extra demonstrations ( n = 5) were the most frequent accommodation, followed by extra breaks ( n = 3), picture cards ( n = 2), and hand-over-hand assistance ( n = 1); some respondents stated that they did not provide accommodations. The findings indicate that a clear set of accommodation for motor skill assessments does not exist, though some commonalities were reported. Further research is necessary to understand the impact of accommodations in the assessment process, as well as which accommodations are needed and/or effective.
