Published: November 2019

OBJECTIVE

Traumatic cerebrovascular injury (TCVI) is a rare and serious complication of traumatic brain injury (TBI). Various forms of TCVIs have been reported, including occlusions, arteriovenous fistulas, pseudoaneurysms, and transections. They can present at a variety of intervals after TBI and may manifest as sudden episodes, progressive symptoms, and even delayed fatal events. The purpose of this study was to analyze cases of TCVI identified at a single institution and further explore types and characteristics of these complications of TBI in order to improve recognition and treatment of these injuries.

METHODS

The authors performed a retrospective review of cases of TCVI identified at their institution between 2013 and 2016. A total of 5178 patients presented with TBI during this time period, and 42 of these patients qualified for a diagnosis of TCVI and had adequate medical and imaging records for analysis. Data from their cases were analyzed, and 3 illustrative cases are presented in detail.

RESULTS

The most common type of TCVI was arteriovenous fistula (86.4%), followed by pseudoaneurysm (11.9%), occlusion (2.4%), and transection (2.4%). The mortality rate of patients with TCVI was 7.1%.

CONCLUSIONS

The authors describe the clinical characteristics of patients with TCVI and provide data from a series of 42 cases. It is important to recognize TCVI in order to facilitate early diagnosis and treatment.
A comparison of digital subtraction angiography and computed tomography angiography for the diagnosis of penetrating cerebrovascular injury
Authors: Ares William J. , Jankowitz Brian T. , Tonetti Daniel A. , Gross Bradley A. , Grandhi Ramesh
Published: November 2019

OBJECTIVE

Penetrating cerebrovascular injury (PCVI) is a subset of traumatic brain injury (TBI) comprising a broad spectrum of cerebrovascular pathology, including traumatic pseudoaneurysms, direct arterial injury, venous sinus stenosis or occlusion, and traumatic dural arteriovenous fistulas. These can result in immediate or delayed vascular injury and consequent neurological morbidity. Current TBI guidelines recommend cerebrovascular imaging for detection, but there is no consensus on the optimum modality. The aim of this retrospective cohort study was to compare CT angiography (CTA) and digital subtraction angiography (DSA) for the diagnosis of PCVI.

METHODS

The records of all patients presenting to two level I trauma centers in the United States between January 2010 and July 2016 with penetrating head or neck trauma were reviewed. Only those who had undergone both CTA and DSA were included. Clinical and neuroimaging data were collected, and PCVIs were stratified using a modified Biffl grading scheme. DSA and CTA results were then compared.

RESULTS

Of 312 patients with penetrating trauma over the study period, 56 patients (91% male, mean age 32 years) with PCVI met inclusion criteria and constituted the study cohort. The mechanism of injury was a gunshot wound in 86% (48/56) of patients. Twenty-four (43%) patients had sustained an angiographically confirmed arterial or venous injury. Compared with DSA as the gold standard, CTA had a sensitivity and specificity of 72% and 63%, respectively, for identifying PCVI. CTA had a positive predictive value of 61% and negative predictive value of 70%. Seven patients (13%) required immediate endovascular treatment of PCVI; in 3 (43%) of these patients, the injury was not identified on CTA. Twenty-two patients (39%) underwent delayed DSA an average of 25 days after injury; 2 (9%) of these patients were found to harbor new pathological conditions requiring treatment.

CONCLUSIONS

In this retrospective analysis of PCVI at two large trauma centers, CTA demonstrated low sensitivity, specificity, and positive and negative predictive values for the diagnosis of PCVI. These findings suggest that DSA provides better accuracy than CTA in the diagnosis of both immediate and delayed PCVI and should be considered for patients experiencing penetrating head or neck trauma.

Published: November 2019

OBJECTIVE

Head CT is sometimes performed immediately after minor head injury; however, which cases develop into chronic subdural hematoma (CSDH) remains unclear. Here, the authors retrospectively reviewed the rare cases of CSDH treated surgically in which early head CT had been performed after the initial head trauma.

METHODS

A total of 172 patients (133 male and 39 female, median age 76 years) underwent surgery for CSDH at Gunma University Hospital between April 2010 and December 2017. Among these patients were 23 who had visited Gunma University Hospital or a nearby hospital and had undergone head CT within 7 days after the initial head trauma. Characteristics of the initial head CT were examined to identify indicators of subsequent CSDH.

RESULTS

Among the 23 CSDH cases (17 male and 6 female, median age 80 years), CT scans were obtained on the day of the initial injury (day 0) in 19 cases (25 sides) and 1–7 days after injury in 12 cases (19 sides); scans were obtained during both periods in 8 cases (12 sides), so that a total of 44 sides were examined. These CT scans were divided into two groups according to when they were obtained; cases in which scans were taken during both periods were included in both groups. Head CT performed on the day of injury showed normal findings in 5 (20%) of 25 sides, thin subdural effusion (SDE) ≤ 6 mm in 16 (64%) of 25 sides, thick SDE > 6 mm in 3 (12%) of 25 sides, and acute subdural hematoma (ASDH) in 1 (4%) of 25 sides. CT from 1–7 days after trauma showed thick SDE in 9 (47%) of 19 sides, thin SDE in 8 (42%) of 19 sides, and ASDH in 2 (11%) of 19 sides. A high-density line in the lateral direction (onion skin–like) was found between the skull and the brain in 9 (35%) of 26 sides with SDE on initial CT 0–7 days after the injury.

CONCLUSIONS

ASDH was not a common cause of CSDH. Head CT at the time of trauma that precedes CSDH often showed SDE. Such SDE that precedes CSDH was often close to the detection limit of CT immediately after the injury but became more apparent from the day after the injury.
Effect of preoperative antiplatelet or anticoagulation therapy on hemorrhagic complications in patients with traumatic brain injury undergoing craniotomy or craniectomy
Authors: Greuter Ladina , Ullmann Muriel , Mariani Luigi , Guzman Raphael , Soleman Jehuda
Published: November 2019

OBJECTIVE

Traumatic brain injury (TBI) is common among the elderly, often treated with antiplatelet (AP) or anticoagulation (AC) therapy, creating new challenges in neurosurgery. In contrast to elective craniotomy, in which AP/AC therapy is mostly discontinued, in TBI usually no delay in treatment can be afforded. The aim of this study was to analyze the effect of AP/AC therapy on postoperative bleeding after craniotomy/craniectomy in TBI.

METHODS

Postoperative bleeding rates in patients treated with AP/AC therapy (blood thinner group) and in those without AP/AC therapy (control group) were retrospectively compared. Furthermore, univariate and multivariate analyses were conducted to identify risk factors for postoperative bleeding. Lastly, a proportional Cox regression analysis comparing postoperative bleeding events within 14 days in both groups was performed.

RESULTS

Of 143 consecutive patients undergoing craniotomy/craniectomy for TBI between 2012 and 2017, 47 (32.9%) were under AP/AC treatment. No significant difference for bleeding events was observed in univariate (40.4% blood thinner group vs 36.5% control group; p = 0.71) or Cox proportional regression analysis (log rank χ2 = 0.29, p = 0.59). Patients with postoperative bleeding showed a significantly higher mortality rate (p = 0.035). In the univariate analysis, hemispheric lesion, acute subdural hematoma, hematological disease, greater extent of midline shift, and pupillary difference were significantly associated with a higher risk of postoperative bleeding. However, in the multivariate regression analysis none of these factors showed a significant association with postoperative bleeding.

CONCLUSIONS

Patients treated with AP/AC therapy undergoing craniotomy/craniectomy due to TBI do not appear to have increased rates of postoperative bleeding. Once postoperative bleeding occurs, mortality rates rise significantly.
A combination of mesenchymal stem cells and scaffolds promotes motor functional recovery in spinal cord injury: a systematic review and meta-analysis

Published: November 2019

OBJECTIVE

There is controversy about the role of scaffolds as an adjunctive therapy to mesenchymal stem cell (MSC) transplantation in spinal cord injury (SCI). Thus, the authors aimed to design a meta-analysis on preclinical evidence to evaluate the effectiveness of combination therapy of scaffold + MSC transplantation in comparison with scaffolds alone and MSCs alone in improving motor dysfunction in SCI.

METHODS

Electronic databases including Medline, Embase, Scopus, and Web of Science were searched from inception until the end of August 2018. Two independent reviewers screened related experimental studies. Animal studies that evaluated the effectiveness of scaffolds and/or MSCs on motor function recovery following experimental SCI were included. The findings were reported as standardized mean difference (SMD) and 95% confidence interval (CI).

RESULTS

A total of 34 articles were included in the meta-analysis. Analyses show that combination therapy in comparison with the scaffold group alone (SMD 2.00, 95% CI 1.53–2.46, p < 0.0001), the MSCs alone (SMD 1.58, 95% CI 0.84–2.31, p < 0.0001), and the nontreated group (SMD 3.52, 95% CI 2.84–4.20, p < 0.0001) significantly improved motor function recovery. Co-administration of MSCs + scaffolds only in the acute phase of injury (during the first 3 days after injury) leads to a significant recovery compared to scaffold alone (SMD 2.18, p < 0.0001). In addition, the cotransplantation of scaffolds with bone marrow–derived MSCs (SMD 1.99, p < 0.0001) and umbilical cord–derived MSCs (SMD 1.50, p = 0.001) also improved motor function following SCI.

CONCLUSIONS

The findings showed that scaffolds + MSCs is more effective than scaffolds and MSCs alone in improving motor function following SCI in animal models, when used in the acute phase of injury.
Treatment approaches for Scheuermann kyphosis: a systematic review of historic and current management
Authors: Huq Sakibul , Ehresman Jeffrey , Cottrill Ethan , Ahmed A. Karim , Pennington Zach , Westbroek Erick M. , Sciubba Daniel M.
Published: November 2019

OBJECTIVE

Scheuermann kyphosis (SK) is an idiopathic kyphosis characterized by anterior wedging of ≥ 5° at 3 contiguous vertebrae managed with either nonoperative or operative treatment. Nonoperative treatment typically employs bracing, while operative treatment is performed with either a combined anterior-posterior fusion or posterior-only approach. Current evidence for these approaches has largely been derived from retrospective case series or focused reviews. Consequently, no consensus exists regarding optimal management strategies for patients afflicted with this condition. In this study, the authors systematically review the literature on SK with respect to indications for treatment, complications of treatment, differences in correction and loss of correction, and changes in treatment over time.

METHODS

Using PubMed, Embase, CINAHL, Web of Science, and the Cochrane Library, all full-text publications on the operative and nonoperative treatment for SK in the peer-reviewed English-language literature between 1950 and 2017 were screened. Inclusion criteria involved fully published, peer-reviewed, retrospective or prospective studies of the primary medical literature. Studies were excluded if they did not provide clinical outcomes and statistics specific to SK, described fewer than 2 patients, or discussed results in nonhuman models. Variables extracted included treatment indications and methodology, maximum pretreatment kyphosis, immediate posttreatment kyphosis, kyphosis at last follow-up, year of treatment, and complications of treatment.

RESULTS

Of 659 unique studies, 45 met our inclusion criteria, covering 1829 unique patients. Indications for intervention were pain, deformity, failure of nonoperative treatment, and neural impairment. Among operatively treated patients, the most common complications were hardware failure and proximal or distal junctional kyphosis. Combined anterior-posterior procedures were additionally associated with neural, pulmonary, and cardiovascular complications. Posterior-only approaches offered superior correction compared to combined anterior-posterior fusion; both groups provided greater correction than bracing. Loss of correction was similar across operative approaches, and all were superior to bracing. Cross-sectional analysis suggested that surgeons have shifted from anterior-posterior to posterior-only approaches over the past two decades.

CONCLUSIONS

The data indicate that for patients with SK, surgery affords superior correction and maintenance of correction relative to bracing. Posterior-only fusion may provide greater correction and similar loss of correction compared to anterior-posterior approaches along with a smaller complication profile. This posterior-only approach has concomitantly gained popularity over the combined anterior-posterior approach in recent years.

Authors: Yogi Jai Prakash , Fiza Bushra , Godara Suraj , Sinha Maheep
Published: November 2019

Background: Chronic Kidney Disease (CKD) can be defined as an estimated glomerular Filtration Rate (eGFR) of less than ml/min/1.73 m2 for a minimum period of three months. CKD is commonly associated with various hematological abnormalities especially anemia. Aim: The present study was planned to assess the hematological variations in CKD patients as compared to healthy subjects. Method: Fifty patients diagnosed with CKD were enrolled for the study. Fifty age and sex-matched healthy subjects constituted the control group. Result: On comparison of the hematological profile, it was observed that all enrolled CKD patients were anemic with hemoglobin (Hb) less than 13g/dL in males and less than 12 g/dL in females. The mean Hb levels were as low as 7.50 + 1.55 g/dL (P< 0.0001). Correspondingly, the total RBC count of CKD patients was also low. It was also observed that the platelet count was slightly low among CKD patients. However, the mean level was comparable with the control group (P=NS). On further analysis, it was observed that among fifty CKD patients, 46% (n=23) suffered from severe anemia i.e. Hb < 7 gm/dL whereas 48% had moderate anemia i.e. Hb between 7-9.9 gm/dL. However, only 12 % (n=6) CKD patients suffered from thrombocytopenia i.e. platelets count < 1.50 lack/ cmm. Conclusion: Hematological abnormalities may lead to several associated morbidities and may pose a challenge for the maintenance of overall health status for CKD patients. Hence, there is a need to monitor the hematological profile of CKD patients especially those on dialysis so that any abnormality can be detected and managed accordingly.

Objective: To study the association between physical and psychological problems perceived by parents and the IQ of their children. Methods: We studied 981 children in the child development center at Ahmednagar. Median age at followup was 7.8y (Q25=5.6y and Q75=10.4y, Babies underwent IQ evaluation by Binet Kamat scale (n=981); also their physical and psychological problems perceived by parents were documented. We categorized children into 4 categories using a number of problems (physical and psychological separately) viz 1 (no problem), 2 (1 problem), 3 (2 problems), 4 (>2 problems). When we looked at physical problem data, 555 (56.6%) had no problem, 251 (25.6%) had 1, 117 (11.9%) had 2, and the remaining 58 (5.9%) had more than 2. For psychological problems like not interested in studies, speech problems don't remember, don't understand, cannot concentrate, fears, etc. The distribution was 221 (22.5%), 212 (21.6%), 222 (22.6%) and 326 (33.3%) respectively. Result: The increasing trend of mean IQ for physical problem parameters from nil to >2 categories and decreasing prevalence of low IQ using the Binet Kamat scale were not significant. However, for psychological problems, the decreasing and statistically significant trend (p=0.000) was present for mean IQ, and a significant increasing trend (p=0.029) for the prevalence of low IQ was observed. Conclusion: Psychological problems were associated with IQ. Numbers of problems were inversely correlated with IQ.

Published: November 2019

The continuous modernization of the education system makes the problems of the quality of teacher training increasingly relevant. Moreover, the measures taken to improve the system of teacher education are largely confined to the introduction of new organizational and managerial mechanisms and practically do not affect the internal content and technological structure of the teacher training process.

Modern pedagogical universities are constantly looking for innovative models of training teachers that will be able to solve non-standard social and professional tasks. However, recent studies in this area do not fully take into account the nature of pedagogical activity and conditions of its formation. Thus, the need arises for a special study of the processes and means of updating the content and technologies of teacher training in order to control the level of students’ professional competencies development, as required by educational and professional standards. This means the creation of a special educational system in a pedagogical university, which can provide a harmonious and synchronous mastering by future specialists of both subject knowledge and methods of pedagogical activity.

The article provides a theoretical study aimed at identifying key patterns of designing a new content for teacher education, the basis of which is the formation of a future teacher as a subject of his own professional activity. The author describes the experience of using a subject-oriented model of education, implemented at Bashkir State Pedagogical University n.a. M. Akmulla. The effectiveness of this model is confirmed by the high level of students’ mastery of designing methods and constructing the educational process, as well as their positive experience in the implementation of educational activities.

Authors: Kosova E. A. , Khalilova M. Yu.
Published: November 2019

The paper studies the problem of developing the massive open online courses (MOOCs) that conform to the content accessibility principles for persons with disabilities. Using the browsing of MOOCs platform catalogues, a total of 56 Russian-language free MOOCs in mathematical disciplines hosted on 5 platforms has been received. By automatic testing using Web Accessibility Checker, the accessibility of the functional and informational content of the MOOCs was evaluated. 73% of MOOCs were found to conform to the syllabus subjects “Probability Theory and Mathematical Statistics”, “Discrete Mathematics” and “Algebra and Geometry”; 8 basic disciplines of higher mathematics education are not covered by online education; 96,4% of the courses have accessibility limitations, especially for people with visual impairment. Accessibility problems are related to shortcomings of the platforms and MOOC developers’ errors. The results show a weak coverage by MOOCs of the basic mathematical disciplines included in the higher education curriculum in Russia and indicate the low content accessibility of the mathematical MOOCs for students with disabilities. The results of the work imply the need for: expanding the range of MOOCs to cover all basic mathematical disciplines; troubleshooting the accessibility in existing courses (pursuant to WCAG); prescription to platforms and developers to strictly adhere to WCAG in future courses.

Published: November 2019

The article raises the problem of the formation of entrepreneurial competencies in response to the current situation in the country’s economy, which arose due to the lack of specialists capable of organizing innovation and technology business in the Territories of advanced socio-economic development (TOSED).

The authors have analyzed the professional preferences of graduates of the National Research Tomsk Polytechnic University (Russia), the University of Zagreb (Croatia), and the University of Lyon (France) and identified the reasons why graduates do not create their own business. In order to determine the necessary cluster of entrepreneurial competencies of university graduates with basic technical education, a survey involving the representatives of Russian and foreign companies working in Russia, including TOSED residents, was conducted. As a result, the authors have received a list of key entrepreneurial competencies necessary for entrepreneurial activities and the formation of graduate competence in the field of management and business.

The authors believe that for the formation of entrepreneurial competence, certain conditions must be created in the educational process for preparing a student for entrepreneurial activities, in particular a number of disciplines (entrepreneurship, technological entrepreneurship, project management, business planning) should be included in the curricula; interactive design training methods aimed to develop graduate’s readiness to create their own business should be applied. It is also necessary to provide an the interaction between universities and business structures, which are mostly the residents of TOSED.

Published: November 2019

The nurse shark(Ginglymostomacirratum), also knownin Portuguese as “tubarãolixa” or “lambaru”, is found mostly in groups of variable size. Specimens inhabit the bottom of the sea, in warm, littoral waters. The nervous system of these sharks arises embryologically from the medullary plate, in which the cephalon develops. The cephalon is divided into three parts, prosencephalon, mesencephalon, and rhombencephalon. These sharks have very sensitive sensors, both mechanoreceptors and electroreceptors, that contribute to the exploration of their surrounding aquatic world and enhance their survival.

Time Dependence of Cosmological Parameters in the Framework of Brans-Dicke Theory
Authors: Roy Sudipto , Ghosh Avik , Dasgupta Adrika
Published: November 2019

In the framework of Brans-Dicke (BD) theory of gravitation, the time dependence of some cosmological parameters have been determined in the present study, for an universe having a FRW space-time with zero spatial curvature. The time variations of the energy density, BD parameter, equation of state (EoS) parameter have been determined, from the field equations of the BD theory, in the initial part of this model. For this purpose, we have used ansatzes relating the scalar field with the scale factor and also linking the BD parameter with the scalar field. For these calculations, an empirical expression for the scale factor has been used. This scale factor has been so chosen that it leads to a signature flip of the deceleration parameter from positive to negative in the course of its evolution with time, indicating a change of phase from decelerated expansion to accelerated expansion. Time dependence of the density parameters for matter and dark energy has also been studied here. Using their expressions we have determined the time dependence of the densities of matter and dark energy. The time variations of all these parameters have been shown graphically. Apart from them, we have also shown the variations of the deceleration parameter and the BD parameter as functions of the scalar field graphically.

Dampak Pulau Reklamasi terhadap Sedimentasi dan Potensi Perkembangan Mangrove Di Pesisir Teluk Jakarta (Muara Angke)
Authors: Putra Indra Setya
Published: November 2019

Mangroves in Indonesia have a large enough area, but in the last 3 decades the area has been reduced to 40%. Besides having a function as a coastal protector, mangroves are also able to maintain the quality of the waters around it. Currently, the construction of a reclamation island in Jakarta Bay is being carried out which will have an impact on the surrounding mangrove forests. Therefore, the purpose of this study was to identify the impact of island reclamation in Jakarta Bay on sedimentation and mangrove growth in surrounding area. This research was conducted with literature studies, vegetation analysis, water quality analysis and also spatial analysis with WorldView-2 satellite imagery. The results showed that the mangrove forests on the coast of North Jakarta, especially in the Muara Angke area tend to increase, especially in the reclaimed island area. The mangrove stands increase by approximately 1.32 ha / year. The density and stem diameters vary in 5 locations. Oxygen levels at the study site are very low but the existing mangrove forests can absorb dissolved heavy metals. The results of the study also show that the area that has the potential to be planted with mangroves is 30 ha. Overall, the sedimentation process helps expand mangrove forests naturally while the bad quality of water does not significantly affect the development of mangroves. On the contrary, the existing mangrove is able to keep the stability of theÂ  water quality in surrounding area.
