Those who participate in service-learning/civic engagement (SLCE) in engineering have a common practice of reflecting on partnerships to determine if they were successful and how they might be improved. But what makes a partnership successful? We wanted to learn more about how and why to quantify partnership success to think “beyond the deliverable,” which is often the singular focus of engineering SLCE projects. To this end, we created a rubric for three dimensions of partnership that we selected after consulting engagement partnership literature: transactional, cooperative, and transformational. Using this rubric, we assessed the 55 completed partnerships of the LSU Community Playground Project (LSUCPP) by plotting scores in a 3-axis coordinate system (transactional as the x-axis, cooperative as the y-axis, and transformational as the z-axis) where a placement closer to (3.0, 3.0, 3.0) means a more universally successful partnership. Within each dimension of partnership, we assessed design, people, and process in equal measure to ensure that we paid adequate attention to each of these key aspects of engineering SLCE efforts. Further, part of this assessment involved surveying constituents (community partners, students, and faculty) about the transformational dimension of completed partnerships. Results showed that our partnerships had high transactional (2.4) and cooperative (2.5) mean scores overall, with a lower transformational mean (1.8). We also identified a transactional/cooperative threshold (2.0/2.0) at which the chance of having a transformational partnership went up; overall, our percentage of highly (2.0 or higher) transformational partnerships was 58%, but 70% of our partnerships that reached the threshold were highly transformational. The aspects of transformation most often identified by our survey respondents included building your capacity personally (81%), building lasting connections with colleagues (73%), and building your capacity professionally (70%). We believe that the method of holistic assessment for community-university partnerships presented here can lead to better engaged partnerships and can be adapted by others who wish to improve their SLCE engineering partnerships.

Objective: Atrial fibrillation is a strong independent risk factor for cardioembolic stroke, with a significant impact on morbidity, mortality and healthcare costs. The aim of our study is to investigate left atrial mechanical function in healthy subjects and patients with atrial fibrillation paroxysms less than 48 hours with low risk of thromboembolic complications at 1 and 28 days after restoration of sinus rhythm.

Methods: Thirty-six healthy controls and patients with paroxysms of non-valvular atrial fibrillation less than 48 hours (n=25) with low-risk CHA2DS2VASc score were included in the study. The mechanical function of the left atrium (LA) was investigated by the 2D speckle tracking program. Transthoracic echocardiography was performed on the 1st and 28th days after restoration of sinus rhythm by pharmacological cardioversion.

Results: Despite the absence of differences in left ventricular systolic function and LA size between the groups, there was a significant decrease in LA deformation and strain rate on day 1 immediately after sinus rhythm recovery in the patients. In the pump phase, the decrease was about 3%, reservoir phase – 10%, and conduit phase – 7% compared to the control group. The strain rate also decreased in the patient group: -1.5 s-1 versus control: -2.14 s-1 (p&lt;0.0001). On the 28th day after restoration of sinus rhythm, there were significant changes in reservoir and conduit functions in patients group in comparison with control group. Global longitudinal LA strain (reservoir phase) decreased to 7%, conduit phase decreased to 11% compared with the control group. In patients group we can see the dynamics during 28 days: pump phase and strain rate were significantly improved, however reservoir and conduit did not significantly change and were lower than in healthy.

Conclusion: Mechanical function of the LA in patients with non-valvular atrial fibrillation and low risk of thromboembolic complications, studied with speckle tracking on the first day was significantly impaired compared with the control group (reservoir phase and strain rate). By day 28, mechanical function improved compared to day 1, but reservoir phase remained significantly lower than normal.
Trepanation revisited in COVID-19 era: A perspective on craniotomy during current pandemic, surgical technique, and complications avoidance
Authors: Krishna Gopal , Singh Ishwar 
Published: November 2022

Background:
Craniotomy creates maximum aerosols threatening the health care workers (HCWs) of operation room. The technique of trepanation and measures to avoid complications has never been described in the literature. The time taken for craniotomy by different instruments has also never been compared.

Methods:
The study included only COVID-positive patients who underwent surgery. Craniotomy was performed using trephine, pneumatic/power drill (PD), and Hudson brace-Gigli saw (HB-GS). Trepanation as done in 32 patients. The generation of aerosols and time taken for craniotomy by these instruments was observed. The droplet spread over a waterproof graph paper of 10 × 10 sq. cm was calculated in 13 cases of all the three craniotomy methods. The technique of trepanation and maneuvers to overcome complications was discussed.

Results:
There was a gross difference in aerosol production and soiling of the surgical drapes, floor, surgeon’s glove, gowns, face shield, goggles, etc. The average number of droplet aerosol in trepanation group was 4.76, 23.6 in drill and 21.3 in Gigli saw method. The average time taken for trepanation, PD, and HB-GS craniotomy was 4.8, 22.8, and 24.4 min, respectively. One mortality secondary to COVID was noted. All the HCWs assisting trepanation were negative for COVID-19 during postoperative follow-up of 7 days. However, 13 members of the surgical team which assisted in electric drill and HB-GS methods were COVID-positive.

Conclusion:
Trepanation should be the preferred method of craniotomy during COVID-19 pandemic as it is associated with the least aerosolization and is the most time efficient.

Географическое положение Республики Саха (Якутия), занимающей значительную часть Арктической зоны России, определяет ее особую роль и ответственность в вопросах освоения развития арктических территорий. Экосистемы Якутии являются уникальным резервом биосферы планеты, более 80% территории не тронуто промышленно-хозяйственным освоением. Экстремальные природно-климатические условия, фрагментарное промышленное освоение, низкая плотность населения, неразвитость транспортной и энергетической инфраструктуры, высокая ресурсоемкость и зависимость от северного завоза, хрупкость экологии – это специфические черты Арктики. Они диктуют необходимость постоянной заботы государства о жителях Арктики. Говоря об Арктике, невозможно не упомянуть её огромный энергоресурсный резерв – около 20% мировых запасов нефти и газа. В районах Арктики есть уникальные возможности для применения лучших технологий, материалов и инноваций для применения в промышленности и производстве в силу хрупкости арктической экосистемы. Текущее состояние и темпы развития арктических территорий Республики Саха (Якутия) во многом не соответствуют их потенциалу и значению. Исходя из приоритетов государственной политики в развитии Арктики важно выстраивание четкой и единой системы по развитию арктических территорий, учитывающих особую специфику макрорегиона.
The geographical position of the Republic of Sakha (Yakutia), which occupies a significant part of the Arctic zone of Russia, determines its special role and responsibility in the development of the Arctic territories. Ecosystems of Yakutia are a unique reserve of the planet’s biosphere, more than 80% of the territory is untouched by industrial and economic development. Extreme natural and climatic conditions, fragmented industrial development, low population density, underdeveloped transport and energy infrastructure, high resource intensity and dependence on northern delivery, fragility of the ecology – these are specific features of the Arctic. They dictate the need for constant state care for the inhabitants of the Arctic. Speaking about the Arctic, it is impossible not to mention its huge energy reserve – about 20% of the world’s oil and gas reserves. The Arctic regions have unique opportunities to apply the best technologies, materials and innovations for industrial and manufacturing applications due to the fragility of the Arctic eco-system. The current state and rates of development of the Arctic territories of the Republic of Sakha (Yakutia) largely do not correspond to their potential and significance. Based on the priorities of state policy in the development of the Arctic, it is important to build a clear and unified system for the development of the Arctic territories, taking into account the special specifics of the macroregion.

Approach to Ischemic Stroke
Authors: Wunder Meaghan 
Published: November 2022

An approach to managing acute ischemic stroke includes recognition, investigations, treatment, and secondary prevention. Firstly, facial drooping, limb weakness and slurred speech are some common signs that should raise the suspicion for stroke. Upon presentation, investigations, including the national institute of health stroke scale and a CT head, should be done to rule out intracranial hemorrhage and diagnose an ischemic stroke. The treatment principles for an acute ischemic stroke focus on removing or dissolving the occlusion to maintain or reinstate perfusion of the brain. Finally, patients suffering ischemic stroke should be admitted to the acute stroke unit and monitored for complications. Basic medical management of comorbidities should also be considered to prevent subsequent ischemic episodes. This article will explain each of these processes in more detail to help develop a basic approach to the management of an acute ischemic stroke.
Prevention of Hamstring Injuries in Male Soccer Athletes
Authors: Teymourlouei Arya 
Published: November 2022

Abstract
Background: One of the most frequently injured muscle groups in soccer is the hamstring group. Soccer players have high rates of hamstring injury (HSI) due to frequent sprinting, changes in direction and similar high-risk activities. Such movements put immense stress on the hamstrings which can lead to injury. Over the last decade, at least four different HSI prevention programs and techniques have been explored in research. The purpose of this review is to assess the effectiveness of these methods.
Methods: Studies in this review were collected using multiple database searches of PubMed. A total of six studies were selected, all either randomized controlled trials (RCTs) or cluster-RCTs. The selected trials were from various soccer leagues in Denmark, Japan, the Netherlands, and the United States.
Results: The most prevalently studied method is the Nordic hamstring exercise (NHE). Studies that utilized the NHE, either as a stand-alone or within a program, reduced the risk of HSI by 15-71%. In addition, effective programs were characterized by progressively increasing the difficulty of exercises and high compliance rates.
Conclusion: Studies that utilized the NHE showed effectiveness in the prevention of hamstring injuries in male soccer athletes. Based on the limited research available, it is unclear whether adding other exercises to prevention programs further reduces injury risk. More research is needed to explore new and existing prevention methods in a variety of populations and regions.
