Authors: Licci Maria , Guzman Raphael , Soleman Jehuda 
Published: October 2019

OBJECTIVEComparing prenatal and postnatal surgical repair techniques for myelomeningocele (MMC), in utero fetal surgery has increasingly gained acceptance and is considered by many specialized centers the first choice of treatment. Despite its benefits, as demonstrated in the Management of Myelomeningocele Study (MOMS), including reduced need for CSF shunting in neonates and improved motor outcomes at 30 months, there is still an ongoing debate on fetal and maternal risks associated with the procedure. Prenatal open hysterotomy, fetoscopic MMC repair techniques, and subsequent delivery by cesarean section are associated with maternal complications. The aim of this systematic review is to assess the available literature on maternal and obstetric complication rates and perinatal maternal outcomes related to fetal MMC repair.METHODSThe authors identified references for inclusion in this review by searching PubMed and MEDLINE, with restrictions to English language, case series, case reports, clinical trials, controlled clinical trials, meta-analyses, randomized controlled trials, reviews, and systematic reviews. The rate of maternal and obstetric complications was analyzed based on studies focusing on this issue and presenting clear results on the matter.RESULTSOf 1264 articles screened, 36 were included in this systemic review, whereof 11 were eligible for data analysis and comparison. The average overall rate of maternal and obstetric complications corresponds to 78.6%. The majority of the described events are obstetric complications, varying from chorioamniotic membrane separation in 65.6% of cases, oligohydramnios in 13.0% of cases, placental abruption in 5.0% of cases, spontaneous or preterm premature membrane rupture in 42.0% of cases, and early preterm delivery in 11.3% of cases due to uterine dehiscence, occurring in 0.9% of cases. The most common medical complications are development of pulmonary edema occurring in 2.8%, gestational diabetes in 3.7%, gestational hypertension/preeclampsia in 3.7%, and need for blood transfusions in 3.2% of cases. Limitations of the review arise from the lack of data in the current literature, with maternal and obstetric complications being underreported.CONCLUSIONSAlthough the efforts of further advancement of intrauterine prenatal MMC repair aim to increase neonatal outcomes, maternal health hazard will continue to be an issue of crucial importance and further studies are required.

OBJECTIVEThe authors evaluated the long-term clinical outcome of a total posterior arthroplasty system in the surgical treatment of lumbar spinal stenosis with degenerative spondylolisthesis.METHODSBetween June 2006 and July 2007, 10 patients with neurogenic claudication due to spinal stenosis and single-level degenerative spondylolisthesis were enrolled in a nonrandomized prospective clinical study. The patients were evaluated with radiographs and MRI scans, the visual analog scale (VAS) for back and leg pain, the Oswestry Disability Index (ODI), and the SF-36 health survey preoperatively and at 6 weeks, 3 months, 6 months, 1 year, 2 years, 3 years, 7 years, and 11 years postoperatively.RESULTSThe mean VAS score for leg pain dropped from 83.5 before surgery to 13 at 6 weeks and 17 at 11 years after surgery. The mean VAS score for back pain dropped from 56.2 preoperatively to 12.5 at 6 weeks and 14 at 11 years after surgery. The mean ODI score decreased from 49.1 preoperatively to 13.5 at 6 weeks and 16 at 11 years after surgery. MRI at 11 years demonstrated stenosis adjacent to the stabilized segment in one patient. This patient was not symptomatic. The authors did not find evidence of progression of the spondylolisthesis in any of the cases. In one patient, conversion to posterolateral fusion was performed due to an early device malfunction.CONCLUSIONSThe results of this 11-year follow-up study demonstrate that, in patients with spinal stenosis and degenerative spondylolisthesis, decompression and posterior arthroplasty maintain clinical improvement and radiological stability.

OBJECTIVERecent trials have shown the safety and benefits of fetoscopic treatment of myelomeningocele (MMC). The authors’ aim was to report their preliminary results of prenatal fetoscopic treatment of MMC using a biocellulose patch, focusing on neurological outcomes, fetal and maternal complications, neonatal CSF leakage, postnatal hydrocephalus, and radiological outcomes.METHODSPreoperative assessment included clinical examination, ultrasound imaging, and MRI of the fetus. Patients underwent purely fetoscopic in utero MMC repair, followed by postoperative in utero and postnatal MRI. All participants received multidisciplinary follow-up.RESULTSFive pregnant women carrying fetuses affected by MMC signed informed consent for the fetoscopic treatment of the defect. The mean MMC size was 30.4 mm (range 19–49 mm). Defect locations were L1 (2 cases), L5 (2 cases), and L4 (1 case). Hindbrain herniation and ventriculomegaly were documented in all cases. The mean gestational age at surgery was 28.2 weeks (range 27.8–28.8 weeks). Fetoscopic repair was performed in all cases. The mean gestational age at delivery was 33.9 weeks (range 29.3–37.4 weeks). After surgery, reversal of hindbrain herniation was documented in all cases. Three newborns developed signs of hydrocephalus requiring CSF diversion. Neurological outcomes in terms of motor level were favorable in all cases, but a premature newborn died due to CSF infection and sepsis.CONCLUSIONSThe authors’ preliminary results suggest that fetoscopic treatment of MMC is feasible, reproducible, and safe for mothers and their babies. Neurological outcomes were favorable and similar to those in the available literature. As known, prematurity was the greatest complication.

Introduction. Increasing demands of precise geometry measurements by science and industry cause the necessity of improvement in an associated branch of legal and practical metrology. One of the most significant fields is the measurement of internal dimensions and so the issues with the unit of meter transfer. Now we face the situation when the current accuracies of National standards of different levels in corresponding traceability chain (reference rings measurements) get close to each other. This means that we have to make the standard of upper level more precise. One of the obvious ways is to apply the latest ultra-stable laser locked to a frequency comb.Objective. The objective is to propose possibilities for improvement of the National secondary standard of the unit of length by researching its measuring capabilities to minimize measurement uncertainty.Materials and methods. The calculation of expanded uncertainty of internal diameter measurements by the National secondary standard of the unit of length is performed according to the international document «Guide to the Expression of Uncertainty in Measurement» JCGM 100:2008 approved by BIPM. The secondary standard research results represented in previous reports and publications are also taken into consideration.Results. Detailed uncertainty budget for the proposed measuring system is given as well as graphical data representing the accuracy improvement.Conclusion. Actions for minimization of measurement uncertainty components of the National secondary standard of the unit of length in the field of reference ring internal diameter measurements in combination with state-of-the-art laser interferometer system improve it to the next frontiers of accuracy and precision.

Authors: Mukhin Nikolay V. 
Published: October 2019

Introduction. Microacoustic sensors based on surface acoustic wave (SAW) devices allow the sensor integration into a wafer based microfluidic analytical platforms such as lab-on-a-chip. Currently exist various approaches of application of SAW devices for liquid properties analysis. But this sensors probe only a thin interfacial liquid layer. The motivation to develop the new SAW-based sensor is to overcome this limitation. The new sensor introduced here uses acoustic measurements, including surface acoustic waves (SAW) and acoustic methamaterial sensor approaches. The new sensor can become the starting point of a new class of microsensor. It measures volumetric properties of liquid analytes in a cavity, not interfacial properties to some artificial sensor surface as the majority of classical chemical and biochemical sensors.Objective. The purpose of the work is to find solutions to overcome SAW-based liquid sensors limitations and the developing of a new sensor that uses acoustic measurements and includes a SAW device and acoustic metamaterial.Materials and methods. A theoretical analysis of sensor structure was carried out on the basis of numerical simulation using COMSOL Multiphysics software. Lithium niobate (LiNbO3) 127.86° Y-cut with wave propagation in the X direction was chosen as a substrate material. Microfluidic structure was designed as a set of rectangular shape channels. A method for measuring volumetric properties of liquids, based on SAW based fluid sensor concept, comprising the steps of: (a) providing sensor structure with the key elements: a SAW resonator, a high-Q set of liquid-filled cavities and intermediate layer with artificial elastic properties between them; (b) measuring of resonance frequency shift, associated with the resonance in liquid-filled cavity, in the response of weakly coupled resonators of SAW resonator loaded by periodic microfluidic structure; (c) determination of volumetric properties of the fluid on the basis of a certain relationship between the speed of sound in liquid, the resonant frequency of the set of liquid-filled cavities, and the geometry design of the cavity.Results. The new sensor approach is introduced. The eigenmodes of the sensor structure with a liquid analyte are carried out. The characteristic of sensor structure is determined. The key elements of introduced microfluidic sensor are a SAW structure, an acoustic metamaterial with a periodic set of microfluidic channels. The SAW device acts as electromechanical transducer. It excites surface waves propagating in the X direction lengthwise the periodic structure and detects the acoustic load generated by the microfluidic structure resonator. The origin of the sensor signal is a small frequency change caused by small variations of acoustic properties of the analyte within the set of microfluidic channels.Conclusion. The principle of the new microacoustic sensor, which can become the basis for creating a new class of microfluidic sensors, is shown.

Authors: Kholkin Victor V. , Kholkin Vladimir Yu. 
Published: October 2019

Introduction. It is necessary to ensure the reliability of measurements when operating high-precision measurement setups. The elements displacement of the measurement path introduces measurement results distortions, especially in measurement setups operating in the microwave range. It is necessary to monitor the elements positions of the measurement setup to ensure the measurements reliability. The monitoring should be performed during the measurement, and the control device should be connected to the automatic control system of the measurement setup, and it should neither mechanically affect the setup elements nor introduce the electrical and electromagnetic interferences.Objective. The objective of the present work is a design of the control system, which allows monitoring of elements displacements of the high precision measuring setup with an accuracy of 1.0·10–4 mm. And the designed control system should neither mechanically affect the controlled elements nor introduce the electrical and electromagnetic interferences, thus allowing the digital signal processing.Materials and methods. The designed system utilizes optical methods of the displacements monitoring, which are based on the geometric optics principles. The charge-coupled devices (CCD) to record the system response to optical path changes are used.Results. Two designs of the control system for the displacement monitoring of the high precision measurement setup elements are presented. The first system design allows detecting the elements displacement occurrence, and the second system design allows to identify the displaced element. The system is capable to register the elements displacements with accuracy of 1.0·10–4 mm and monitor the elements positions while vibration exposures. The system does not mechanically or electromagnetically affect the controlled elements. All system elements are resistant to the microwave radiation and increased background radiation, excluding CCD that should be placed outside the active zone. The mathematical simulation allows assessing the sensitivity of the designed optical control system. The system sensitivity increasing method by the optical path increasing and corrective reflector using is proposed.Conclusion. The designed control system for the displacements monitoring of the high precision measurement setup elements meets the requirements imposed on it. The system allows the digital signal processing and can withstand the increased microwave, X-ray and background radiation. The designed system is much simpler to implement in comparison with systems based on other physical principles. The novelty of the control system technical solution is confirmed by the patent.

Despoblación, desarrollo y cultura: triángulo cómplice
Authors: Sáez Pérez Luis Antonio 
Published: October 2019

La mayoría de las políticas frente a la despoblación en España han tenido desarrollos incompletos, no solo en su implementación sino también a la hora de su diseño, que ha sido sectorial o anclado en contextos superados. Tiene esto que ver con unas concepciones desenfocadas de lo que es la despoblación, en cuanto a su métrica, su ámbito localista y, especialmente, sus causas, que omiten las que son decisivas, muy vinculadas al deseo y a la mentalidad vigente, intangibles y cualitativas, aunque también influyan los mercados y la política.
Su interpretación desde las teorías del desarrollo local como marco integrador de un buen diagnóstico y una praxis consecuente, también incurre en una visión fundamentalmente cuantitativa y maximizadora, imposible e inconveniente, dentro de la cual el medio rural periférico difícilmente resulta atractivo. Es preciso un cambio de mentalidad que amplíe las percepciones sobre el bienestar y el desarrollo, y la cultura aparece como una herramienta clave, como catalizador de una mirada más rigurosa por un mejor conocimiento, una reflexión más profunda y una sensibilidad más cómplice hacia lo rural.
Las políticas que se propongan han de poner en relación la despoblación con un desarrollo que contemple la realización personal dentro de una comunidad en la que la cultura fomente la creatividad, la cooperación y la acogida.

Published: October 2019

The article deals with a theoretical analysis of the motivational sphere of servicemen’ personality who participated in combat operations, which allowed to outline the understanding of the empirical picture of the research of the structure of the serviceman’ motivation. Valid empirical techniques have been applied: the questionnaire “The Level of Personality Claims” (“LPC”) (Herbachevskyi, 1990), the Questionnaire “The Level of Social Expectations” (“LSE”) (Popovych, 2017), the questionnaire “Purpose in Life Test” (“PIL”) (Leontiev, 2006). Several psychological content parameters were clarified and substantiated, psychological structure of motive of a serviceman was constructed. The interrelationships between psychological content parameters of servicemen’ motivation with social expectations (p<0,05; p<0,01) and sense-oriented orientations (p<0,05; p<0,01) were examined empirically. The article presents and analyzes an incredibly large list of correlation galaxies of social expectations with sense-oriented orientations. It is noted that the study of psychological content parameters of servicemen’ motivation and established interrelations are significant in the context of performing professional-service (combat) activities. The obtained empirical results of the study of the servicemen’ motivation showed that the motivational structure is an incredibly complicated complex education. It is stated that the selected set of methods and methods of statistical data processing allowed to qualitatively interpret the parameters of the motivational structure, to separate one parameter from another, to outline the content features.
It is made synthesis that the obtained results of the study of psychological content parameters of servicemen’s motivation will help the command-officer structure to operationalize the tasks of professional, official (combat) activity. The results of the study may be interesting to heads of military units, command officers, heads of military educational institutions, educators, as well as researchers in the field of military psychology, psychology of personality motivation. The perspective of the nearest research is determined.
