Published: October 2020

Abstract
The elastic, thermal and ultrasonic properties of zirconium nanowire (Zr-NW) have been investigated at room temperature. The second and third order elastic constants (SOECs and TOECs) of Zr-NW have been figured out using the Lennard–Jones Potential model. SOECs have been used to find out the Young’s modulus, bulk modulus, shear modulus, Poisson’s ratio, Pugh’s ratio, Zener anisotropic factor and ultrasonic velocities. Further these associated parameters of Zr-NW have been utilized for the evaluation of the Grüneisen parameters, thermal conductivity, thermal relaxation time, acoustic coupling constants and ultrasonic attenuation. On the basis of the above analyzed properties of Zr-NW, some characteristics features of the chosen nanowire connected with ultrasonic and thermo-physical parameters have been discussed.
Blast waves propagation in magnetogasdynamics: power series method
Authors: Devi Munesh , Arora Rajan , Singh Deepika 
Published: October 2020

Abstract
Blast waves are produced when there is a sudden deposition of a substantial amount of energy into a confined region. It is an area of pressure moving supersonically outward from the source of the explosion. Immediately after the blast, the fore-end of the blast wave is headed by the shock waves, propagating in the outward direction. As the considered problem is highly nonlinear, to find out its solution is a tough task. However, few techniques are available in literature that may give us an approximate analytic solution. Here, the blast wave problem in magnetogasdynamics involving cylindrical shock waves of moderate strength is considered, and approximate analytic solutions with the help of the power series method (or Sakurai’s approach [1]) are found. The magnetic field is supposed to be directed orthogonally to the motion of the gas particles in an ideal medium with infinite electrical conductivity. The density is assumed to be uniform in the undisturbed medium. Using power series method, we obtain approximate analytic solutions in the form of a power series in

, where a
0 and U are the velocities of sound in an undisturbed medium and shock front, respectively. We construct solutions for the first-order approximation in closed form. Numerical computations have been performed to determine the flow-field in an ideal magnetogasdynamics. The numerical results obtained in the absence of magnetic field recover the existing results in the literature. Also, these results are found to be in good agreement with those obtained by the Runge–Kutta method of fourth-order. Further, the flow variables are illustrated through figures behind the shock front under the effect of the magnetic field. The interesting fact about the present work is that the solutions to the problem are obtained in the closed form.

Abstract
Objective
This study presents national estimates on symptoms consistent with postpartum anxiety (PPA) and postpartum depression (PPD) and the association between these conditions and possible risk and protective factors in women who gave birth in Canada.

Methods
Data were collected through the Survey on Maternal Health, a cross-sectional survey administered in Canada’s ten provinces between November 2018 and February 2019 among women who gave birth between January 1 and June 30, 2018. A total of 6558 respondents were included. Weighted prevalence estimates were calculated, and logistic regression was used to model the relationship between symptoms consistent with PPA, PPD, and potential risk factors.

Results
Overall, 13.8% of women had symptoms consistent with PPA, while the prevalence of having symptoms consistent with PPD was 17.9%. Results of the logistic regression models indicated that women who had a history of depression were 3.4 times (95% CI 2.7–4.2) more likely to experience symptoms consistent with PPA and 2.6 times more likely to experience symptoms consistent with PPD (95% CI 2.2–3.2) compared with those who did not. Women who reported good, fair, or poor physical health were 2.4 times more likely to experience symptoms consistent with PPD (95% CI 2.0–2.9) and 2.0 times more likely to experience symptoms consistent with PPA (95% CI 1.7–2.4) compared with those who reported very good or excellent health. Maternal marital status, other postpartum maternal support, and sense of community belonging were also significant.

Conclusion
This study highlights that a history of depression and good, fair, or poor physical health are associated with an increased odds of symptoms consistent with PPA and PPD, while other maternal support and sense of community belonging are associated with a decreased odds of these conditions.

Published: October 2020

The aim of the study was to develop an algorithm for conservative treatment of lumbosacral pain syndrome (PCBS) caused by spondylolysis in athletes and ballet dancers.
Materials and methods. The study included 212 patients athletes and ballet dancers with PCBS caused by spondylolysis (171 people) and grade III spondylolisthesis (41 people) of the lumbar vertebrae. Clinical, neurological, and X-ray studies, ultrasonography, computed tomography, scintigraphy, functional testing, as well as markers of bone resorption (calcium in urine) and bone formation (alkaline phosphatase) were performed.
Results. All patients underwent conservative treatment: functional therapy, physiotherapy, ozone and drug therapy. Functional rehabilitation treatment included three stages: 1 relief of pain; 2 restoration of support ability and stability of the spine; 3 restoration of special motor skills. As a result of treatment, the functional parameters of the muscles stabilizing the spine improved (tone, contractile activity, bioelectric parameters), and the muscle imbalance was eliminated. After treatment, in radiographs, in most cases, a defect was observed in the arch of the vertebra, but it was much smaller in width and did not affect professional performance. Complete restoration of the bone structure in the area of the arc defect was observed only with acute pathology, complete cessation of sports load and a long (1 year or more) sparing regimen (9 people). Excellent and good results were obtained in 171 (80.7%) patients, satisfactory in 36 (16.9%) patients. Five (2.4%) patients with spondylolisthesis were not able to continue their professional activities, the result of conservative treatment was regarded as unsatisfactory. Three of them were subsequently underwent surgical treatment.
Conclusion. The development of an individual program of conservative rehabilitation treatment for athletes and ballet dancers with spondylolysis and grade I and II spondylolisthesis, adequate and timely use of rehabilitation features lead to eliminating muscle imbalance and strengthening muscle corset. This, in turn, will contribute to the relief of pain, restoration of professional performance, prevention of progression of the area of bone reconstruction of the vertebral arches and spondylolisthesis

Authors: Ukolov K. Yu. , Ayzenberg V. L. , Kapirina M. V. , Mikitina M. E. 
Published: October 2020

Introduction. Spinal anesthesia is widely used in major orthopedic. Primary hip and knee arthroplasty are major surgical procedures associated with significant potential morbidity in elderly patients. This increases requirement to surgical and anesthetic procedures. Some studies provide evidence that levobupivacaine when used as an alternative to bupivacaine in spinal anesthesia is less cardiotoxic and neurotoxic.
Aim: To compare the efficacy and safety of these two spinal anaesthetic agents in elderly patients undergoing primary hip or knee replacement.
Patients and methods. The study included 90 patients performed arthroplasty with spinal anesthesia. I group patients received spinal anesthesia bupivacaine 0,5%, II group patients received intrathecal levobupicavaine 0.5%. Group I (n=60), 22 (37%) underwent primary hip arthroplasty, and 38 (63%) patients that underwent primary knee arthroplasty with mean age (65,4 + 6,5). Group II (n=30), 18 (60%) patients that underwent primary total hip arthroplasty and 12 (40%) patients that underwent primary knee arthroplasty with mean age (65,5 + 8,1). Anesthesia algorithm did not differ for both groups.
Results. Vital parameters and adverse effects in relation to spinal anesthesia were observed. Decrease of heart rate was more significant in group II. Blood pressure parameters were comparable to both groups though, 10% of Group I patients received infusion of norepinephrine for treatment of hypotension. The two groups were comparable with glucose and lactate variations as well as the duration of analgesia and postoperative nausea and vomiting. No postoperative delirium was noted in both groups.
Conclusion. Spinal anesthesia with levobupivacaine is more safe for elderly patients undergoing knee and hip arthroplasty.

Authors: Bardyugov Petr S. , Parshikov Mihail V. 
Published: October 2020

Objective. The aim of the study is to analyze the design features of orthopedic appliances used to preserve or restore the transverse arch of the foot and determine the most promising product.
Materials and methods. Orthopedic products that were used to correct forefoot flattening in 350 patients aged 1782 years were analyzed. Of the total number of patients, 321 were women, and only 29 were men; 252 people were diagnosed with transverse flatfoot of stages 12, while maintaining high elasticity of the arches, and in 34 cases, there was a pronounced rigidity. Flatness was combined with valgus deformity of one finger in the range of 20300 in 218 patients. The pathological process reached stages 34, and the degree of elasticity of the arches was low in 98 patients. The products were used after various operations in 86 patients, while they were used as a conservative correction in the rest.
Results. All orthopedic appliances were divided into groups according to several criteria (design features and functional perspectives). An analysis of the strengths and weaknesses of the first three allowed us to identify the fourth group, which included products that provided the ability to adjust the size of the forefoot and at the same time restored the transverse arch. They were successfully used both in the rehabilitation period, after various reconstructive operations, and with conservative treatment.
Conclusion. One of the main goals in the treatment of this category of patients is restoration of the transverse arch of the foot during flattening (surgically, conservatively, or in combination), should be used according to indications and, if necessary, be combined with other corrective elements. All this will allow to achieve both therapeutic and cosmetic results and ultimately improve their quality of life.

Published: October 2020

<p>The US food and drug administration (FDA) has long called for clinical outcomes assessments (COA), such as patient-reported outcomes (PRO), to be ‘fit-for-purpose’ meaning the COA has been validated to support the context of use. The FDA’s recent patient-focused drug development guidance series has renewed the importance of ensuring that COA is ‘fit-for-purpose’ and valid. In addition, the FDA has recommended that COA be collected electronically and that the electronic (eCOA) system and devices also be validated. Advancing technology requires eCOA systems and devices to evolve; eCOA devices may change over time. As bring your own device (BYOD) models gain popularity and acceptance, devices may also be mixed within trials. Changes in eCOA devices or mixing devices may require equivalence testing to prove validity across platforms. The aim of this article is to provide an overview of the different types of validation at both the assessment level and the eCOA system (device) level to help clinical trial sponsors determine the appropriate level of validation or equivalence testing required for COA used in their clinical trials. </p>

Published: October 2020

En el presente articulo argumento el papel que tiene el derecho como fuerza transformadora para revocar o al menos aliviar los síntomas que padece la naturaleza. Está claro que se puede hacer mucho para aliviar las dolencias que aquejan al planeta y a su biodiversidad. Sobretodo en Colombia, el quinto país más biodiverso del planeta y donde coexisten más de 340 ecosistemas diferentes de especies animales y vegetales. El posconflicto plantea retos en materia ambiental y por ello debemos avanzar hacia una nueva ética que transforme el Estado y el derecho, una ética en la que los animales y demás sujetos de la naturaleza ocupen un lugar de respeto y empatía y no sean visto como meros instrumentos.
Adicción y metabolismo digital. Una mirada desde la filosofía de la tecnología
Authors: Baranzoni Sara 
Published: October 2020

Propósito/Contexto. Este artículo tiene como propósito analizar los fenómenos de adicción digital en el contexto contemporáneo, que se caracteriza por transformaciones tecnológicas en continua expansión.
Metodología/Enfoque. El análisis se lleva a cabo desde el punto de vista de la filosofía de la tecnología y siguiendo la perspectiva farmacológica que formula el filósofo Bernard Stiegler en el marco de los estudios digitales, esto es, una visión de la tecnología, siempre y al mismo tiempo, como veneno y remedio para el ser humano.
Resultados/Hallazgos. El artículo arroja luz sobre los orígenes y las consecuencias de semejante situación adictogénica, enfocándose en las causas socioeconómicas y en las posibilidades de escape que la tecnología misma nos proporciona; el problema ético se pone en relación con los estilos de vida de los usuarios y la pregunta es si las tecnologías actuales dejan lugar para un mejoramiento de las condiciones cotidianas o si solo amplifican el malestar que la vida contemporánea crea.
Discusión/Conclusiones/Contribuciones. Finalmente, se proporcionan algunos ejemplos enfocados en la reeducación y la comprensión del farmakon, para devolver autonomía y capacidad de toma de decisiones a los adictos, desarrollando en ellos un “saber consumir” que alivia los efectos tóxicos de la relación con los dispositivos y los dota de una capacidad de inventar nuevas posibilidades para encontrar una forma distinta de relación en y con la sociedad.

Authors: Mandel Mark , Saloky Kaitlin , Mirenda William , Seeley Andrea , Seeley Mark 
Published: October 2020

Case:
A 1-week-old female patient presented to our clinic with bilateral dislocated hips and was subsequently treated in a Pavlik harness. Harness treatment failed requiring a closed reduction and spica cast application. In the Post-Anesthesia Care Unit (PACU), the patient was found to have a right humerus fracture. Six weeks after cast application, the patient was found to have nondisplaced bilateral femur fractures prompting a genetics evaluation. The patient was subsequently found to have osteogenesis imperfecta type 3.

Conclusion:
Perioperative fractures in pediatric patients should raise suspicion for osteogenesis imperfecta. Early diagnosis can improve the management of hip dysplasia and allow for early bisphosphonate therapy.
