Adenosine in facilitating aneurysm clipping
Authors: Manoharan Ganesh Kumar , Prasad R. J. V. V. , Kumar Senthil , Arvind K R
Published: April 2022

Introduction:

Intracranial aneurysms are the one of most complicated conditions confronted by a neurosurgeon. Even though endovascular procedure is preferred, open surgery and clipping of the aneurysm still remains gold standard procedure for many aneurysms. Proximal control of the parent vessel remains one of the most critical steps in clipping the aneurysms and this can be achieved by various ways such as temporary clipping and transient cardiac standstill using adenosine. Temporary clipping is associated with complications such as infarct and injury to the vessel, whereas temporary hypotension using adenosine provides a way for successful clipping of the aneurysm. Here, we present our experience with adenosine in patients undergoing clipping of aneurysms in our institution between 2017 and 2020.

Methodology:

It is a retrospective cohort study conducted on patients undergoing craniotomy and clipping of aneurysms and in those where adenosine is not contraindicated. Patients are divided into Group A where adenosine is not used and Group B where adenosine is used.

Results:

In Group B, where adenosine is used, clipping was easier, with less incidence of intraoperative ruptures, less usage of Temporary clip (TC) and less incidence of infarct, reduce clipping time with no side effects.

Conclusion:

Adenosine-induced transient cardiac arrest and hypotension are a safe and effective method in facilitating aneurysm clipping.
BRAVE

Published: April 2022

The practice of emergency medicine has reached its cross roads. Emergency physicians (EPs) are managing many more time-dependent conditions, initiating complex treatments in the emergency department (ED), handling ethical and end of life care discussions upfront, and even performing procedures which used to be done only in critical care settings, in the resuscitation room. EPs manage a wide spectrum of patients, 24 h a day, which reflects the community and society they practice in. Besides the medical and “technical” issues to handle, they have to learn how to resolve confounding elements which their patients can present with. These may include social, financial, cultural, ethical, relationship, and even employment matters. EPs cannot overlook these, in order to provide holistic care. More and more emphasis is also now given to the social determinants of health. We, from the emergency medicine fraternity, are proposing a unique “BRAVE model,” as a mnemonic to assist in the provision of point of care, adaptive leadership at the bedside in the ED. This represents another useful tool for use in the current climate of the ED, where patients have higher expectations, need more patient-centric resolution and handling of their issues, looming against the background of a more complex society and world.
Contrecoup Extradural Hematoma
Authors: Punia Prashant , Chugh Ashish , Gotecha Sarang
Published: April 2022

Extradural hematoma (EDH) is a fairly common entity in neurosurgical practice but EDHt at a contrecoup site and crossing a cranial suture is rare. The authors present a case of EDH due to contrecoup injury in whom sutural diastases was noted and hematoma was seen to be crossing the adjacent suture. This was accompanied with subdural hematoma (SDH) at the coup site. According to the best of our knowledge, it makes the case only the 13th such to be reported in adults. A 27-year-old male patient was brought by relatives with a history of fall from a height resulting in head trauma over the left posterior parietal region. The patient presented with headache at the site of impact. Computed tomography (CT) scan of the brain revealed an undisplaced fracture of parietal bone on the left side (coup site) along with a small concavo-convex hyperdense lesion suggestive of a SDH. Scan also revealed a large biconvex, hyperdense lesion in the right frontoparietal region (contrecoup site). The hematoma was seen to be evidently crossing the coronal suture. Sutural diastases of coronal suture was suspected and the same was noticed intraoperatively. Approximately 80cc of clot was removed and hemostasis was achieved through coagulation of the middle meningeal artery and via dural hitch sutures. Contrecoup EDH across the adjacent suture with sutural diastases is rare as it does not follow the set rules of hematomas. A high index of suspicion is central in arriving at a rapid diagnosis and an early surgery to achieve a favorable outcome. The authors recommend a CT scan along all three planes along with a three-dimensional reconstruction for ready diagnosis. Contrecoup EDH with sutural diastases is a distinct and potentially dangerous entity and neurosurgeons should be aware of the same.

Authors: Hutzler Sean , Simmons Michael , Guardiola Jose , Richman Peter B.
Published: April 2022

Introduction:

History is an important component of emergency department risk stratification for chest pain patients. We hypothesized that a significant portion of patients would not be able to accurately report their history of coronary artery disease (CAD) and diagnostic testing.

Methods:

We prospectively enrolled a convenience sample of a cohort of adult ED patients with a chief complaint of chest pain. They completed a structured survey that included questions regarding prior testing for CAD and cardiac history. Study authors performed a structured chart review within the electronic medical record for our 6-hospital system. Results of testing for CAD, cardiac interventions, and chart diagnoses of CAD/acute myocardial infarction (AMI) were recorded. Categorical data were analyzed by Chi-square and continuous data by logistic regression.

Results:

About 196 patients were enrolled; mean age 57 ± 15 years, 48% female, 67% Hispanic, 50% income <$20,000/year. About 43% (95% confidence interval [CI] 35%–51%) of patients stated that they did not have CAD, yet medical records indicated that they were CAD+. With increasing age, patients were more likely to accurately report the absence of CAD (P < 0.001). There was no association between patients reporting no CAD, but CAD+ in records with respect to the following characteristics: female gender (P = 0.37), Hispanic race (P = 0.73), income (P = 0.41), less than or equal to high school education (P = 0.11), and private insurance (P = 0.71). For patients with prior AMI, 7.2% (95% CI 2.7%–11%) reported no prior history of AMI.

Conclusions:

Within our study group from a predominantly poor, Hispanic population, patients had a poor recall for the presence of CAD in their medical history.

Authors: Paul Debashish , Gupta Nipun , Patra Arun Kumar , Saurav  , Krishna Prasad G V
Published: April 2022

Background:

The concept of labor analgesia is widely unknown to the antenatal women and parturients in the Indian medical setup.

Aims:

The aim of this study was to assess the knowledge, attitude, and practice of labor analgesia in antenatal women visiting the antenatal clinic in a tertiary care hospital.

Methodology:

One hundred twenty women in the antenatal period between the age group of 18 and 40 years attending the antenatal clinic were included in the study. A Google form-based questionnaire was used to collect data.

Statistical Analysis:

Ordinal and nominal data were presented as numbers and percentages. Bar diagrams and pie charts were used for graphical representation.

Results:

Twenty-one (17.5%) respondents, out of 120, were aware of labor analgesia. Among the rest 99, 13 participants did not have knowledge nor they wanted to gather information further. Out of 86 unaware respondents, 62 (72.1%) were interested in acquiring the knowledge of labor analgesia and rather would be comfortable if the treating obstetrician imparts the information; 46 (53.5%) of them wanted the information to be imparted during the obstetric consultation sessions and 10 (11.6%) respondents considered the best time for gathering awareness for labor analgesia at, or after the onset of labor pain. The major concerns of the respondents for labor analgesia were the safety of their health and the effect on the baby.

Conclusions:

Awareness of labor analgesia in Indian antenatal women is low. The treating obstetrician should impart knowledge regarding labor analgesia in the pre- and antenatal period which should be supplemented with more emphasis during the prelabor period.
Management of a Pediatric Subtrochanteric Fracture
Authors: Iqbal Mohammed Schezan , Kulsreshtha Vikas , Harikrishnan B. , Singh V. B.
Published: April 2022

Pediatric subtrochanteric fractures have been treated historically with intramedullary nailing, sliding hip screw, or pediatric proximal femoral locking plates, which are often based on the fracture pattern or availability of suitable implants. It is desirable to use a technique of fixation that will not only restore the hip biomechanics but also be a stable construct. We present a conventional technique of reduction and fixation of a subtrochanteric femoral fracture in an 8-year-old child using an unconventional implant, namely an adult proximal humerus locking plate, with a successful outcome and no postoperative complications.
Measured quantum groupoids on a finite basis and equivariant Kasparov theory
Authors: Crespo Jonathan
Published: April 2022

In this article, we generalize to the case of measured quantum groupoids on a finite basis some important results concerning the equivariant Kasparov theory for actions of locally compact quantum groups, see Baaj and Skandalis (1989, 1993). To every pair

(A,B)

of

\mathrm{C}^*

-algebras continuously acted upon by a regular measured quantum groupoid on a finite basis

\mathcal{G}

, we associate a

\mathcal{G}

-equivariant Kasparov theory group

\mathsf{KK}_{\mathcal{G}}(A,B)

. The Kasparov product generalizes to this setting. By applying recent results by Baaj and Crespo (2017, 2018) concerning actions of regular measured quantum groupoids on a finite basis, we obtain two canonical homomorphisms

J_{\mathcal{G}}:\mathsf{KK}_{\mathcal{G}}(A,B)\rightarrow\mathsf{KK}_{\hat{\mathcal{G}}}(A\rtimes{\mathcal{G}},B\rtimes{\mathcal{G}})

and

J_{\hat{\mathcal{G}}}:\mathsf{KK}_{\hat{\mathcal{G}}}(A,B)\rightarrow\mathsf{KK}_{\mathcal{G}}(A\rtimes\hat{\mathcal{G}},B\rtimes\hat{\mathcal{G}})

inverse of each other through the Morita equivalence coming from a version of the Takesaki–Takai duality theorem. We investigate in detail the case of colinking measured quantum groupoids. In particular, if

\mathbb{G}_1

and

\mathbb{G}_2

are two monoidally equivalent regular locally compact quantum groups, we obtain a new proof of the canonical equivalence of the associated equivariant Kasparov categories, see Baaj and Crespo (2017).

Authors: Calvopiña Manuel , Guerra-Vilca Jhaneth , Leon-Monar Astrid , Boadas-Salazar Asisclo , Ocaña-Amores Edwin
Published: April 2022

Abdominal angiostrongyliasis, a foodborne parasitic disease, caused by the zoonotic nematode Angiostrongylus costaricensis, is a rarely reported human eosinophilic enteritis, only been diagnosed in the America continent. The adult worm invades arteries, most frequently those in the right ileocolic region, and causes abdominal symptoms. Currently, the only definitive diagnosis is by identifying the parasite in surgical specimens. By observing adult worms of A. costaricensis inside the mesenteric arteries, we diagnosed and treated the first known case from the Amazon region of Ecuador. A 2-year-old indigenous Shuar, who during the previous 2 months had been diagnosed with having dysentery, typhoid fever, and appendicitis; presented with fever, painful distended abdomen, a palpable abdominal mass on the right flank, and bloody diarrhea, accompanied by leukocytosis with eosinophilia of 20.6%. The child completely recovered after partial surgical resection of the transverse and descending colon, and treatment with mebendazole. This case substantiates that not only the existence of the parasite, but also active transmission of the disease is occurring in Ecuador. Physicians, travelers, as well as decision-making authorities should be alerted to the importance of this foodborne zoonosis and of the need for research to determine the geographical distribution and possible prevention strategies.

Critical analysis of the Russian-Bulgarian political relations based on Far Right Parties 2013-2018
Authors: Mestan Adnan
Published: April 2022

The main subject of this study is the political relations between Bulgaria and Russia, which are based on the extreme right party. In Europe, which has recently been the cradle of democracy, major political changes have begun to take place, and it has been observed that extreme right-wing parties have risen due to the economic crisis. At the same time, the rise of these far-right parties was evaluated as an opportunity by Russia to destabilize the European Union, and the fact that Russia was were already sanctioned by Europe for its bad relations with Ukraine. Since Bulgaria was a satellite of the Soviet Union, Russia has tried to establish a political relationship with that country through the far-right parties by activating its old relations. As a result, Russia has tended to stop the enlargement process of both NATO and the European Union in this way

Published: April 2022

"Current tractor market demands light weight components to meet the need of cost-effective tractor with higher fuel efficiency. Skid assembly is one of the heaviest subsystems of a tractor subjected to the loads from the external implements, ground, engine and internal loads due to transmission line. It consists of several casting components with many geometric features such as flanges, bosses etc. These geometric features are very essential in terms of assembly, manufacturing & packaging considerations. Effective material distribution for tractor parts play a significant role in reducing the overall weight of the tractor. OEMS are moving from conventional grey cast iron housing to aluminum, which is not only the light weighting solution but also provides strength, stiffness, and resistance to corrosion. Aluminum die casting wall thickness is key for die casting part as the thickness increase strength decreases and also cause void, pits, porosity problems. With air pockets and rib patterns, we can make housings much lighter with minimal wall thickness without sacrificing structural integrity. Conventional methods like topology optimization needs good interpretation skills and usually take many iterations to finally converge. In this paper, a new innovative approach of combining various optimization techniques, an integrated optimization methodology, has been proposed to achieve quick design convergence. In the current work, Initially, a solid topology optimization at the substructure level has been performed to quickly identify sensitive regions of the structure that have the most impact on the performance. Using these sensitive regions, a design space is generated with shell elements in the form of ribs. A topology optimization is conducted again to identify the critical regions of the ribs, and subsequently sizing optimization is used to determine the optimum thicknesses of the ribs. The final suggested optimized rib pattern has given improved performance compared to baseline design. A substructure methodology also has been proposed to reduce the optimization run time in this paper. "

Cálculo de las propiedades térmicas y mecánicas de nanotubos de carbono a partir de la dispersión de fonones
Authors: García-Merino José Antonio
Published: April 2022

La importancia de estudiar a los nanotubos de carbono (CNT) desde una perspectiva de cristalinidad es de suma importancia ya que sus propiedades son altamente modificadas en función de su distribución atómica. Este trabajo, describe el cálculo de propiedades térmicas y mecánicas de CNT cristalinos (C-CNT) y de baja cristalinidad (LC-CNT) por medio del estudio numérico de la dispersión de fonones. La estructura de bandas y la densidad de estados de los fonones se obtuvieron por medio de un programa de cómputo (QuantumATK) y considerando CNT de las mismas dimensiones morfológicas. La diferencia en la dispersión de fonones entre los materiales resultó determinante en las propiedades térmicas y mecánicas. A pesar de que la capacidad calorífica es similar en ambos CNT, se observó una diferencia de 1 orden de magnitud para la conductividad térmica. Así mismo, el módulo de Young se calculó en 5.4 MPa para los C-CNT y en 73.6 MPa para los LCCNT. Estas diferencias se atribuyen a los valores de la velocidad del sonido en los materiales. Por otra parte, los CNT tienen una gran relación de aspecto y por tanto presentan una alta polarización molecular, lo cual lo hace un material atractivo para modular las propiedades mecánicas mediante el efecto de electrostricción. El cambio de la densidad y el módulo de Young se calcularon considerando una fuente de luz con una irradiancia entre 0.1 a 1.0 GW/cm2, tomando como base las propiedades ópticas lineales y no-lineales de los CNT de investigaciones previas. Los resultados aproximan las propiedades térmicas y mecánicas de C-CNT y/o LC-CNT analizando los modos fundamentales de vibración atómica.

Penerapan Natural Language Processing Untuk Mengidentifikasi Kalimat Ambigu pada Surat Kabar Menerapkan Metode Shift Reduce Parsing
Authors: Wita Elya
Published: April 2022

Natural Language Processing focuses on the interaction between computers and the natural language used by humans. In other words, the computer process extracts information from input in the form of natural language and / or produces output which is also in the form of natural language.Newspapers are printed sheets containing reports that occur in the community. However, the titles of newspapers often have an ambiguous meaning. When a written or spoken word, phrase, sentence, or even paragraph contains ambiguity, it is automatically ineffective and communicative for the reader or listener. For this reason, it is necessary to identify sentences to make it easier for readers to understand the meaning of an ambiguous title.To make it easier to identify ambiguous sentences in newspapers requires a shift Reduce parsing algorithm, using the Shift Reduce parsing algorithm can be useful to find out what the news writer wants to convey.

The Fourth Industrial Revolution, Industry 4.0, promises trillions of dollars of value creation by connecting billions of sensors and actuators to analytical engines, thereby creating the Industrial Internet of Things (IIoT). This revolution will push decision making to the edge and connect the edge to the center. The revolution faces three major technical challenges: interoperability between devices, security of edge devices and legacy infrastructure. This paper describes an implementation of a fundamentally new authentication and encryption technology (“dOISP™), that allows devices to connect regardless of operating system and transport technology. With dOISP™ a network manages its own security without use of certificates or Trusted Third Parties or any centralized or externalized source of trust and without human intervention – the network itself maintains a distributed source of trust that changes continuously and always assumes that authentication must be refreshed for every session. This technology enables the acceleration of Industry 4.0 initiatives thereby increasing their net present value as well as reducing the organizational costs of network security and reducing the risk of successful attack.

However, scholars have shown concerns about Pakistani students’ poor civic sense and teamwork skills.  This current study aimed to examine the perspectives of local rural college students on civic responsibility and teamwork as outcomes of service-learning. Data were collected from 136 college students who participated in a service-learning project designed and implemented in Chitral Lower’s local college district. A questionnaire consisting of two scales: civic responsibility and teamwork, was used for data collection. The questionnaire was piloted before data collection. Experts checked content validity, and reliability was assessed by using Cronbach’s alpha. The principal component analysis technique was applied to analyse collected data with a principal component analysis approach. The results showed that respondents strongly agreed that service-learning significantly improved their sense of civic responsibility and teamwork skills. The results of this study extensively support the findings of previous research studies. However, it is suggested that the findings of this study may further be investigated in other contexts for a better understanding of the role of service-learning as civic and teamwork pedagogy.
Trabalho e inserção social em contextos urbanos e rurais: raça e cor em Minas Gerais no século XIX
Authors:   , Santos Flávia Alves
Published: April 2022

Esta tese teve como objetivo analisar a influência de um contexto socioeconômico mais urbanizado ou mais ruralizado sobre o campo de possibilidades de inserção social dos não brancos na sociedade mineira do século XIX. Para tanto, através da conceituação de raça, cor e trabalho, foram analisadas listas nominativas de Ouro Preto e Guarapiranga entre os anos 1831 e 1838. Por meio destas lentes teóricas, foram examinados os perfis e atuação dos chefes de fogos/domicílios em diferentes setores de atividades. A presença de chefes brancos diferiu significativamente daquela dos não brancos entre os setores analisados em ambas as cidades. De modo geral, observou-se que a maioria dos fogos/domicílios era chefiado por indivíduos pardos e sem escravos. As pequenas posses de cativos, quando existentes, foram mais frequentes que as médias e grandes posses. As condições tanto para brancos, como, principalmente para não-brancos ostentarem uma posição social, passava pelo fato de serem capazes de se distanciar do trabalho, associado à condição de escravo. A diversidade ocupacional da cidade de Ouro Preto nos oitocentos parece ter contribuído com uma pluralidade de atividades que permitia, àqueles não brancos que atingiam a condição de chefe de fogo, alcançarem condições de distinção social, e, obterem pequena, média ou grande posses de escravos. Nesta cidade, o setor denominado “Outras Ocupações” apresentou maior variedade de ocupações, e, junto com o setor “Comerciante” apresentou, também, a maior concentração de escravos para chefes não brancos. Destacou-se neste segmento populacional, um chefe preto Tenente-coronel com 24 escravos. Guarapiranga, por sua vez, se mostrou mais restrita quanto à diversidade de atividades que permitiram a chefes não brancos alcançarem prestígio social através de seu trabalho e posses de escravos. Neste distrito, destaca-se o setor Atividades Manuais e Mecânicas prevalecente dentre chefes não brancos, comumente sem escravos. Quando da presença de escravos, estes foram observados, predominantemente, em pequenos plantéis, havendo raros médios e nenhum grande plantel. A condição de chefe de fogo sem escravos aproximava, parcialmente, brancos e não-brancos nos oitocentos. Chefes de fogos sem escravos que precisavam trabalhar no próprio fogo, aproximavam-se da condição dos escravos, e eram enegrecidos socialmente. Enquanto negros e pardos com escravos poderiam embranquecer socialmente. Assim, o “trabalho” funcionava como um gradiente social de cor nas Minas Gerais dos oitocentos. Em contextos mais urbanizados, como Ouro Preto, este gradiente social da cor se mostrou mais acionado que em contextos mais ruralizados como o de Guarapiranga. Palavras-chave: Ocupação. Escravos. Fogos. Ouro Preto. Guarapiranga.
