Hypertrophic obstructive cardiomyopathy and its outcome following surgical myectomy: a retrospective study

Background: Hypertrophic cardiomyopathy is highly heterogeneous with a diverse anatomy, pathophysiology, and clinical course. It is obstruction to left ventricular outflow that has become the major hallmark of the disease. Septal myectomy has been the gold standard treatment for the relief of left ventricular outflow tract obstruction and cardiac symptoms in both adults and children with obstructive hypertrophic cardiomyopathy. Objective of the study was to evaluate effect of Myomectomy and its impact on survival for a period of one year.Methods: The study design is a retrospective record based observational study. Data was retrieved from previous records both electronic as well as manual records of all the patients who underwent myectomy with or without concomitant procedures such as mitral valve replacement or aortic valve replacement or coronary artery bypass surgery during 2014 to 2018.Results: Majority of the patients 11 (52.4%) in fourth decade i.e. 40-59 years age group. majority were males i.e. 16 (76.2%) and remaining 5 i.e. 23.8% were females. Male to female ratio was 3.2:1. Dyspnoea was present 81% and chest pain in 76.2%. Preoperative LVOT gradient was 86.86±20.33 and post-operative gradient was 23.47±20.49. Conclusions: Operative techniques have evolved from simple myotomy to the present method of extended septal myectomy which can be done in all adult cases of hypertrophic obstructive cardiomyopathy.
ASSESSMENT OF POST-DISCHARGE HEALTH CARE UTILIZATION IN INFANTS WITH NEONATAL OPIOID WITHDRAWAL SYNDROME

Background/Objectives: Children born to mothers with opioid use disorder often show withdrawal effects characterized by increased stress, hyperirritability, tremors, tachycardia, sleep deprivation, and gastrointestinal discomfort, commonly known as “neonatal opioid withdrawal syndrome” (NOWS). Studies have shown that the effect of NOWS can lead to several health-related disorders later in life leading to increased health care utilization. However, detailed study of post-discharge health care utilization, specifically focusing on encounters with the health care system is currently lacking in the literature. Our objective was to evaluate health care utilization in infants who were diagnosed with NOWS during a one-year follow-up period after their discharge from the hospital. Secondly, we wanted to assess the relationship between NOWS related severity measures and post-discharge health care utilization during a one-year follow-up period. Methods: Health Facts data, collected from over 800 contributing CERNER hospitals across the United States, was used to identify infants who were diagnosed with NOWS. Health care utilization during a follow-up period of 365 days after the index period
The effect of shear stress on bovine nucleus pulposus cells

Low back pain affects most people at some point in their lives, and intervertebral disc degeneration is a common cause of this pain. The nucleus pulposus is the first structure to fail in intervertebral disc degeneration. Gaining a greater understanding of the nucleus pulposus cell and its response to mechanical stimuli may be useful in tailoring the next cell-based regenerative therapy and preventative therapies. The nucleus pulposus is a highly hydrated, porous tissue and changes in spinal loading create fluid movement throughout the tissue, which causes fluid shear stress on the tissue and cells. This research has investigated shear stress rates of 0.1, 1.0 and 4.0 dyne/cm2 on bovine nucleus pulposus cells. Steady and pulsed flow were studied over 1, 4, 8 and 24 hours using Ibidi VI0.4 chambers. Results showed shear stress affects the morphology and gene expression of bovine nucleus pulposus cells. Morphological changes associated with cell detachment and reduced proliferation were seen in cells exposed to 1.0 dyne/cm for 4 and 8 hours and 4.0 dyne/cm2 for 1, 4 and 8 hours. After 24 hours in 1.0 dyne/cm2 and 4.0 dyne/cm2 all cells had detached from the Ibidi VI0.4 slides. There was an increase in cell proliferation in cells exposed to 0.1 dyne/cm2 for 4 hours in steady flow and no change in cell number compared to control at 1, 8 and 24 hours in steady and pulsed flow. Changes in gene expression in 4.0 dyne/cm2 flow were consistent with changes associated with catabolic metabolism; downregulation of collagen 2 and aggrecan and upregulation of aggrecanase 1 and 2. Results comparing steady and pulsed flow and gene expression changes at 0.1 and 1.0 dyne/cm2 were inconclusive, further studies with a larger sample size could help to clarify these effects. These findings are important in guiding researchers in the development of optimal perfusion bioreactor conditions for cell-seeded nucleus pulposus regeneration therapies. The implications for research to increase our understanding of fluid flow through the intervertebral disc during exercise as a preventative measure for disc degeneration are also discussed.
The inclusion of disability issues and concepts in the Jordanian national curriculum from the perspective of curriculum planning experts

ABSTRACT This study aimed to investigate the inclusion of disability issues and concepts in the national curriculum (NC) from the perspective of Jordanian curriculum experts, and content analysis was used to analyse interviews with 15 experts. The results revealed that the curriculum experts think that the inclusion of disability issues is not a priority and does not receive enough attention from the Ministry of Education, and they described a variety of barriers to including disability issues in the curriculum. The experts agreed on the importance of the curriculum in increasing awareness of disability issues and changing community attitudes. These positive attitudes of the experts can be used to encourage decision-makers to focus on the inclusion of disability issues and facilitate a successful inclusion process. Finally, the inclusion of disability issues will help in achieving the successful inclusion of persons with disabilities in education and life in general.
Linking Land Tenure and Integrated Watershed Management—A Review

Land tenure is given attention in the general discussions on conservation and management of natural resources, but the necessary holistic approach to understand the linkages is less considered. Thus, we considered a watershed as a unit of reference and Integrated Watershed Management as a holistic land and water resources management approach with various roles and touchpoints with land tenure issues. To examine the role of land tenure on the management of natural resources in watersheds, we reviewed and compiled literature that captures watershed issues, integrating aspects of land tenure, and aiming to identify the key land tenure roles, dynamics, and its influences on integrated watershed management. Land tenure is observed playing various roles in watersheds and, thus, also on integrated watershed management as an approach—as a driver of change, influence for investment decisions, an incentive for adoption of practices, and leading to sustainability. Land tenure dynamics range from land tenure security, land tenure forms, land access and acquisition modalities, and how these aspects of land tenure relate with integrated watershed management.

ParIS+: Data Series Indexing on Multi-Core Architectures

Data series similarity search is a core operation for several data series analysis applications across many different domains. Nevertheless, even state-of-the-art techniques cannot provide the time performance required for large data series collections. We propose ParIS and ParIS+, the first disk-based data series indices carefully designed to inherently take advantage of multi-core architectures, in order to accelerate similarity search processing times. Our experiments demonstrate that ParIS+ completely removes the CPU latency during index construction for disk-resident data, and for exact query answering is up to 1 order of magnitude faster than the current state of the art index scan method, and up to 3 orders of magnitude faster than the optimized serial scan method. ParIS+ (which is an evolution of the ADS+ index) owes its efficiency to the effective use of multi-core and multi-socket architectures, in order to distribute and execute in parallel both index construction and query answering, and to the exploitation of the Single Instruction Multiple Data (SIMD) capabilities of modern CPUs, in order to further parallelize the execution of instructions inside each core.
Modeling and analysis of an islanded, low voltage,inverter-based microgrid

The penetration of Voltage Source Converters (VSCs) interfacing renewable energysources in today’s power system has experienced a steep incline. In microgrids, thepenetration of VSCs can reach 100% during times when the load is supplied exclu-sively through renewables in combination with battery storage, providing a researchfield regarding VSC interaction and control.In this thesis, a real low-voltage, islanded microgrid in Thailand is modelled inSimulinkwith theSimscape Power Systemslibrary. The system consists of a 40 kWPV array, 240 kWh lead-acid battery and a 50 kW diesel generator with a peak loadof 25 kW at a lagging power factor of 0.95. The diesel generator has been omittedto simulate an inverter-based microgrid and focus on VSC interaction.The battery-interfacing VSC is controlled as a grid-forming converter, whereasthe PV-interfacing VSC is operated in grid-feeding mode. Both VSCs are controlledin the(qd)-frame. During peak-load condition the simulation shows a minimumvoltage of 0.89 pu at the load bus. Therefore, a third, small-scale battery-interfacedVSC in closer proximity to the load is integrated and operated in grid-supportingmode with the objective to maintain a minimum load bus voltage of 0.95 pu.It is shown that a 21 kVA-rated VSC can provide adequate voltage regulationthrough active power injection if operated in current-control mode withPv-droopcontrol, given the resistive nature of the low voltage lines. Reactive power can beshared among the VSCs through frequency adjustments of the grid-forming con-verter. The droop control of the grid-supporting VSC is extended with a dead bandto regulate its participation to voltage control. The simulations show that the mi-crogrid remains stable during large load steps, if the droop constants of the formingconverter are below≈4%
Efficiency Improvement of Wireless Power Transfer Based on Multitransmitter System

Multitransmitter wireless power transfer system gets more and more applications as it can maintain high efficiency in a large space range. This article focuses on modeling the multitransmitter system, and proposes an impedance matching method to improve efficiency under lateral-misalignment conditions. The theoretical analysis shows that the maximum transfer efficiency can be achieved as long as the equivalent input impedance of the transmitters is regulated to be the same under misalignment condition. Hence, a double closed-loop control strategy is proposed to realize maximum efficiency point tracking, where the primary control loop adjusts the input impedance of the transmitters through pulsewidth modulation, while the second control loop maintains constant output power by a dc–dc converter. A 500-W prototype is built to validate the feasibility of the proposed method. The efficiency is always higher than 90% with an improvement of up to 20.3% compared to that without such a method when the lateral misalignment increases from 0 to 10 cm (0%–41% of maximum coil size).
Does Concern about Local Crime affect People’s Trust in the Police?

Abstract Trust in institutions is one of the central pillars of the stability of democracies. By exploring a unique database indicative of confidence on Brazilian institutions, this study investigates the effect of concern in local crime on confidence in the police. We explore data from the Confidence in Justice Survey conducted for the period from 2013 to 2014 at the state of Sao Paulo. Our identification strategy is the two-stage least square model, with an individual’s distance to police stations as the instrumental variable. We find that an increase in the total crimes registered reduces confidence in the police. Such results are particularly more apparent in crimes like drug dealing and rape. Exploring heterogeneities in the results, we find that black people are more sensitive to crime rate changes with respect to security, even while living in similar neighborhoods as white citizens. Results also show that those who had prior experience with the police are less sensitive, independent of the quality of police work at the time.
Singular Wire-Driven Series Elastic Actuation with Force Control for a Waist Assistive Exoskeleton, H-WEXv2

This article presents a design of an electrically powered waist-assistive exoskeleton H-WEXv2 to reduce back-muscle fatigue and prevent back-injury of industrial workers. It utilizes a wire-driven mechanism based on a singular series elastic actuation to achieve system performances in aspect of cost, weight, operational time, and system endurance and maintainability for industrial feasibility. This proposed mechanism consisting of a ball screw drive and a series elastic actuator enables H-WEXv2 to accomplish better control maneuverability on powered flexion/extension while maintaining the advantage of allowing natural human walking with almost zero impedance. Also, to transfer torque determined by a high-level controller, a SEA force controller was implemented by measuring elastic displacements of installed spring elements at both hip joints. In order to evaluate the effectiveness of the developed robot installed with the proposed mechanism, electromyographic (EMG) signals of relevant muscles of ten subjects related to target waist motions were measured and compared for three cases: 1) wearing H-WEXv1, 2) wearing H-WEXv2, and 3) wearing nothing. Finally, the statistical analysis on acquired EMG signals verified the effectiveness of waist assistance provided by H-WEXv2.
Methodology and the professional doctorate – the muddy waters of knowledge creation, transfer and workplace capital

ABSTRACT The professional doctorate creates opportunities for shared research and novel findings to inform and shape the workplace and cultivate professional capital. In this paper I discuss my own journey in undertaking an Educational doctorate. I critique how my methodological approach enabled me to successfully cross the range of boundaries that I encountered along my way. As I crossed the boundaries between scientist, teacher and researcher, my chosen approach afforded a framework that appealed to my embedded ‘positivist tendencies’. It permitted me to acknowledge the varied positioning of both myself and others, and the professional learning that takes place within and across each boundary. I was able to question what constitutes knowledge and what the most acceptable approaches to knowledge creation are when boundaries and research paradigms are crossed. This journey provided me with a greater understanding of how and why as individuals we position ourselves in our roles. This understanding underpins my recommendations for supporting professional learning. I discuss the relevance and potential impact of my findings for both practice and for those undertaking an educational doctorate.
A very small sinus venosus type of atrial septal defect: A rare but curable cause of recurrent stroke

Sinus venosus is a rare cardiac defect, which may lead to an interatrial shunt. Diagnosis on echocardiography may be difficult requiring an evaluation by a board-certified cardiologist. We report a case of a 41 year-old male who presented with recurrent episodes of hemiparesis (first left sided, second right sided). Surgical correction of sinus venosus led to resolution of his symptoms.

Tel: +82-33-258-9439, Fax: +82-33-258-2432, Email: rdr0203@gmail.com INTRODUCTION Atrial septal defects close to the superior vena cava are called sinus venosus atrial septal defects (ASD). They often include apparent or true anomalous entry of one or both of the right pulmonary veins into the right superior vena cava or the right atrium. Thus, this malformation can cause interatrial shunting leading to rightventricular overload. Clinical manifestations range from mild to severe in degree, with most patients having minimal symptoms. Cerebral ischemic events in the setting of ASD with normal right ventricular compliance are rare.1-3 We report a case of of a middle aged male with recurrent strokes, who ultimately required surgical correction of a very small sinus venosus type of ASD.
Why scientific practices are not included in Science lessons? What does it go unnoticed for teachers

Despite the importance that research gives to including scientific practices in science education, it reports a lack of effectiveness of the approaches adopted in science classrooms. The efforts made in promoting inquiry-based learning seem not to have been very successful, taking into consideration the current dissatisfaction with the inadequate interpretation of these approaches. This paper attempts to address the issue of the lack of proper scientific practices as shown in the results of a range of research projects and their implications for teacher training, by addressing the following issues: Reasons why the scientific practices are not included in science lessons; the purposes or advantages served by the use of scientific teaching practices in classrooms and how they influence the instruction; the importance of recognising emotions felt in science classrooms; and how to reach competent science teachers who know, not only how to introduce scientific practices properly in their instruction, but who also understand why such practices are necessary in relation to the epistemic knowledge. With the aim of making future teachers aware of the scientific practices advantages, we propose to promote the opportunity of experiencing the implementation of Model-Based Inquiry sequences with SENSe, SENSors, and SENSations, in their classes with their own students.
Students' Entrepreneurial Intentions at Two South African Universities

This comparative, explanatory and cross-sectional quantitative study was aimed at evaluating students’ perspectives of entrepreneurial intentions. The secondary data used comprised of 484 (205 [42.36%] Walter Sisulu University and 279 [57.64%] Tshwane University of Technology) students. The study reported that students at the two universities had similar perceptions of entrepreneurial intentions, and that students from Tshwane University of Technology are more likely to encourage other people to study entrepreneurship education than their Walter Sisulu University counterparts. This paper recommends that entrepreneurship education should be introduced to students at some early stages of their education life. Students’ education that incorporates activities that are real-life based and demanding problem-solving skills such as technology of things (digital technology) may prove to be vital for exposing students to knowledge and useful skills in order for students to generate income and to create employment opportunities.

Total Error in a Big Data World: Adapting the TSE Framework to Big Data

While Big Data offers a potentially less expensive, less burdensome, and more timely alternative to survey data for producing a variety of statistics, it is not without error. The AAPOR Task Force on Big Data and others have called for researchers to evaluate the quality of Big Data using an approach similar to the total survey error (TSE) framework. However, differences in the construction of, access to, and overall data structure between survey data and Big Data make application of TSE difficult. In this article, we seek to develop the Total Error Framework (TEF), an extension of the TSE framework, to be (1) more inclusive and applicable to many types of Big Data, (2) comprehensive in that it considers “total” error, and (3) unified in that it allows researchers to compare errors in Big Data to errors in survey data. After outlining this framework, we then illustrate an application of TEF by comparing error in housing unit area (square footage) estimates collected in a survey (the 2015 Residential Energy Consumption Survey [RECS]) to those estimates found in three Big Data databases (Zillow.com, Acxiom, and CoreLogic).
Phenolic and flavonoid content, and antioxidant activity of honey from Kosovo

In this study, the phenolic and flavonoid content, as well as antioxidant activity of one-hundred honey samples of different botanic origin were analyzed. Eighty-six of these samples are originated from different regions in Kosovo, while the rest fourteen are imported samples that can be found in the Kosovo market. To determine the content of phenolics, flavonoids, and antioxidant activity (2,2-diphenyl-l-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP)), spectrophotometric methods were used. Total phenolic content ranged from 25.76 ± 10.16 to 84.17 ± 30.14 mg GAE/100 g honey, total flavonoid content ranged from 1.11 ± 0.62 to 7.51 ± 3.75 mg CE/100 g honey, FRAP activity varies from 3.65 ± 1.96 to 22.39 ± 12.86 mg TE/100 g honey, while DPPH activity varies from 0.73 ± 0.34 to 2.61 ± 0.93 mg TE/100 g and 22.23 ± 7.82 to 66.92 ± 23.18%, respectively. Due to the correlation matrix, total phenolic content shows positive correlation in all honey samples (mean value of all samples, FRAP: 0.829 and DPPH: 0.804); and total flavonoid content shows also positive correlation within all samples (FRAP: 0.834 and DPPH: 0.813).
