Published: December 2022

Context:
Primary percutaneous coronary intervention (PCI) is the most effective reperfusion therapy with low complication rate in comparison to thrombolysis.

Aims:
We aimed to study the short-term outcomes of primary PCI at a large tertiary care center in India.

Settings and Design:
A prospective cohort of patients with ST-elevation myocardial infarction (STEMI) who underwent primary PCI was enrolled between December 2015 and November 2016.

Subjects and Methods:
The demographic profile, risk factors, clinical characteristics, inhospital complications, and outcomes at 30 days were assessed. The primary outcome was a composite of death, reinfarction, and repeat revascularization. Acute left ventricular failure (LVF), complete heart block (CHB) or bradyarrhythmia, ventricular tachycardia (VT) or ventricular fibrillation, stroke, and major thrombolysis in myocardial infarction bleeding were the inhospital complications that were considered the secondary outcomes.

Results:
A total of 237 STEMI patients with primary PCI were enrolled, accounting for 7.5% of all PCI procedures performed during this period. The mean age was 55.4 ± 11.9 years, and 86.5% were male. The mean window period was 5.1 ± 3.18 h, and the mean door-to-balloon time was 58.4 ± 11.5 min. Prior to PCI, the most often administered antiplatelets were clopidogrel in 54.4% of patients and prasugrel in 55.6%. The aspiration thrombectomy was done in 70.8% of patients. Predilatation with balloon was required in 41.8% of patients. Drug-eluting stents were implanted in 98.3% of patients. The primary outcome was found in 3.3% of patients (deaths – 2.9% and reinfarction – 0.4%) and the secondary outcomes were observed in 13%. The common inhospital complication was CHB or bradyarrhythmia in 5.0% followed by acute LVF in 4.6% and then VT in 2.1%.

Conclusions:
The primary outcome rate is as good as reported in developed Western countries in contemporary treatment practices of STEMI. CHB and acute LVF were the major inhospital complications among patients of STEMI treated with primary PCI.

Authors: Savani Nikita Maheshbhai , Chauhan Rajendra B. , Chudasama Rajesh K. 
Published: December 2022

Introduction:
Although atherosclerotic cardiovascular disease (ASCVD) results have significantly improved in recent years, ASCVD continues to be the world's leading cause of morbidity and mortality. Therefore, in the present study, lifetime risk of ASCVD was calculated in an urban cohort. White-collar employees have higher risk of developing cardiovascular disease events because of their work profile.

Aim and Objectives:
To calculate lifetime predicted risk of ASCVD among study cohort and to explore factors contributing to the disparities of cardiovascular risks.

Materials and Methods:
This was community-based cross-sectional study. The baseline data were collected during the period 2016–2019 from Rajkot city, and their lifetime predicted risk of ASCVD was calculated using ASCVD risk calculator. Crude and adjusted prevalence ratio was calculated.

Results:
The study revealed that 69.25% and 6.37% of participants had low and intermediate lifetime predicted risk of ASCVD, respectively, while the remaining 16.12% and 8.25% had borderline and high risk, respectively.

Conclusion:
This study indicates that increased lifetime predicted risk of ASCVD was associated with increasing age, male, stress, elevated blood pressure, high level of body mass index, and central obesity among participants.
The assessment of earthquake hazard in Italy: a review
Authors: Slejko Dario , Valensise Gianluca , Meletti Carlo , Stucchi Massimiliano 
Published: December 2022

We present a review of the assessment of earthquake hazard in Italy, with special reference to the relationships between hazard models and building codes. After early attempts at hazard assessment in the 19th century, the 28 December 1908, Messina Straits earthquake prompted the inception of the first national seismic legislation, passed in early 1909. Nevertheless, the official building code started to be based on a truly scientific background only after 1980, when the catastrophic Irpinia (southern Italy) earthquake forced the qualified authority to accept a science-based assessment (statistics on the earthquake catalogue data) to support the implementation of the new national seismic zonation. Later on, between 1985 and 2000, the two basic components of seismic hazard assessment, namely the earthquake record and the distribution of earthquake sources, were greatly developed through investigations carried out by the Gruppo Nazionale Difesa dai Terremoti and by the Istituto Nazionale di Geofisica. Along with the improvement of basic data, the Italian seismological community started developing a new hazard model (PS4), based on the concept of seismotectonic probabilism, aimed at supplying the Italian Government with a solid reference frame for updating the seismic zonation and building code. Nevertheless, this goal was achieved only two decades later: on 31 October 2002 a moderate-size earthquake caused the death of 27 children and a teacher in a collapsed school of southern Italy, forcing the qualified authority to take a major step of modernization for the second time in 22 years. The entire Italian territory, including areas of rare and sparse seismicity, was subdivided into four seismic zones, mainly on the basis of PS4 results. In 2004, the Italian seismological community developed MPS04, a fully updated hazard model that was initially conceived only in view of updating the seismic zonation. In 2007, MPS04 was extended to provide design spectra for a new building code, which was finally adopted in 2009, following the disastrous L’Aquila (central Italy) earthquake. The experience of the European project for seismic hazard assessment named SHARE, completed in 2013, represented a step forward and put the basis for a new project, termed MPS19, designed specifically to provide a sound basis for updating the Italian building code.
Navigating the Contemporary Rites of Passage: A Typology of STEM Professional Identity Transition
Authors: Chong Yit Sean , Quek Ai Hwa 
Published: December 2022

Anchored upon a renewed rites of passage perspective, this study employs a narrative inquiry to understand how professional identities are enacted, developed, negotiated, and reconstructed among final year STEM undergraduates in Malaysia. While professional identities are largely studied within the workplace or organisational context, there is limited knowledge of how students make sense of their professional identities during their study. To address this gap, this study explores the dilemmas and dreams of twenty-four final year STEM undergraduates as they were at the critical juncture of transition towards their first full-time career. While the participants shared a common experience of STEM professional identity formation during their childhood and adolescent phases of life, there were variations in how individuals negotiated their professional identities as they reached the crossroads upon university enrolment and graduation. In navigating the liminal phase of uncertainties, negotiation strategies included defending and rethinking STEM professional identities while balancing identities in work and non-work roles. Towards the reconstruction phase, a process of redefining, affirming, and securing STEM professional identity takes place as individuals make sense of their roles and place in the communities. The narrative findings illustrate contemporary dynamics of societal expectations, structural forces and personal agency that facilitate STEM professional transitions. The study also adds insights into emerging discourses surrounding STEM education and talent retention strategies among the contemporary STEM workforce.
Análisis del discurso canalero: la visión de Tejeira desde los enfoques social y político
Authors: Hernández Mojica Maribel 
Published: December 2022

Este artículo científico contiene los resultados de un estudio cualitativo, cuyo objetivo fue analizar el discurso de la novela histórica canalera panameña en la obra Pueblos Perdidos de Gil Blas Tejeira (2016). Como fundamento teórico se utilizó la teoría transdisciplinaria del análisis del discurso(Van Dijk, T. 1992)
Se abordó el análisis del discurso canalero en la obra Pueblos perdidos (Tejeira, 2016); desde dos dimensiones, social y económica por medio de un análisis hermenéutico, lo que permitió develar elementos identitarios que representan los vaivenes que sufrió el Istmo de Panamá de 1880 a 1888 periodo de la construcción del Canal por los franceses.(Tack, 1999)
Los resultados del estudio demostraron que en la dimensión social se visibilizan claramente dos escenarios distintos: por un lado, la inequidad y la desigualdad; y por otro lado tenemos, los privilegios y la comodidad.(Tejeira, 2016) En la dimensión económica sobresale el control ejercido por la élite dominante conformada por franceses y norteamericanos.(Tejeira, 2016)
La importancia de este estudio es que permite enriquecer el entendimiento sobre la construcción de una identidad panameña; además, proporciona un ejercicio del pensamiento crítico sometiendo a escrutinio los argumentos, ideas, juicios del discurso histórico canalero.

Purpose: The performance of smart antenna is affected by antenna array configuration and the direction of arrival estimation (DOA) algorithm used .To have a suitable DOA for an uniform rectangular array (URA),The performance of two dimensional estimation of signal parameters via rotational invariance techniques (2D-SPRIT) that are applied for two different planar dispositions of antenna for URA in Massive Multiple Inputs Multiple Output (Massive MIMO) systems when subjected to the same simulation conditions is comparatively analyzed. The performance of the proposed 2D-ESPRIT algorithm with URA in vertical plane (the case of full-dimensional MIMO) has been compared with that of the existing 2D-ESPRIT algorithm that is applied with URA in horizontal plane.
Methodology: Implementation and simulation of analyzed 2D-ESPRIT algorithms was done in MATLAB and compared considering computational complexity efficiency, DOA estimation precision, estimation failure and variation of Root mean square Error (RMSE) with Signal to Noise Ratio (SNR) and angular spread. MATLAB simulation results got from similar input parameters in a multipath environment are compared to derive a conclusion.
Findings: Simulation results show that the proposed 2D-ESPRIT algorithm applied in vertical plane outperforms the existing 2D-ESPRIT algorithm applied in horizontal plane for all considered performance criteria that include estimation precision, running time and Root mean square error (RMSE).
Recommendation: Other researchers interested in working on 2D-ESPRIT algorithms are recommended to improve the work reported in this paper by further reducing computational complexity observed in 2D-ESPRIT algorithm with URA in vertical plane at large antenna array size to reflect the standard of full-dimension MIMO.

Published: December 2022

The bone tumor (BT) remains a sickness type that is marked by unlimited cell growth and results in numerous early demises worldwide. Hence, diagnosing BT in the earlier phases and classifying them turned into a vital job for healing the sick person. Springing out of the bone, BT disseminates throughout the body swiftly impacting sick persons. By assessing histopathological images (HpIs), BT’s swift and early prognosis could be started. Centered upon this, a survey has been performed on BT identification employing diverse approaches to image processing and observed that there remain several issues, and the adversities did by BT enhance while it is unidentified at the right time. The abnormalities in the bone image are identified from the region of interest. For these problems, many research works were carried out to develop several Computer-aided diagnosis systems, having as a major challenge to define the features that better represent the images to classify. To overcome the problem this paper aims to develop Recurrent CONVoluted neural networks (Rec-CONVnet) based classification for the assessment of tumor type based on analyzing MRI images. For the smoothing process wiener filter is used to reduce the mean square error (MSE) and hence image enhancement is done by using a convoluted Gabor filter. The performance analysis is done by comparing with three traditional methods such as Dense Convolutional neural network (DCNN), Random Forest (RF), and Decision Tree (DT) in terms of accuracy, sensitivity specificity, f1 score, recall, and is found that the proposed Rec-CONVnet achieves 98.34% of accuracy, 97.96% of precision, 98.72% of recall, 98.33% of specificity and 98.32% of f1-score.

Authors: Victor Mwanakasale , Venkatajothi Ramarao , Mwaba Mwansa 
Published: December 2022

Introduction: Human African Trypanosomiasis (HAT) is a parasitic disease caused by an invasive parasite called the human trypanosomes. The disease is divided into two stages, namely stage-1 and stage-2. The aim of this study was to determine the prevalence and risk factors for seizures in stage-2 of Rhodesiense HAT (rHAT) in Zambia from January 2013 to July 2022.
Methodology: This was a retrospective cross-sectional study. All case files of patients that were laboratory diagnosed with rHAT from endemic hospitals in Zambia from January 2013 to July 2022 were reviewed.
Results: A total of 54 casefiles of all HAT patients from January 2013 to July 2022 were reviewed. There were 2 cases with history of seizures in stage-2, one Caucasian and one black Zambian out of 5 and 49 patients, respectively. There was a statistically significant difference in the prevalence rate of seizures between Caucasian and black patients (P<0.05). There was no statistically significant difference in age in occurrence of seizures between patients less than 30 years of age and those 30 years and above (P>0.05). In addition there was no statistically significant difference in occurrence of seizures between sexes (P>0.05).
Conclusion: Being a Caucasian is probably a risk factor for seizures in stage-2 of Rhodesiense HAT in Zambia.

Authors: Jarusiripot Chutima , Sungthong Daoroong 
Published: December 2022

In this study, several ratios of water hyacinth to acid solution were varied from 1:10, 1:20, 1:30, and 1:40, in order to find the optimum ratio for biohydrogen and biomethane production. The pretreated water hyacinth was used as substrates to produce hydrogen in the first stage anaerobic digestion. Then the residue from hydrogen production was used as substrate for methane production in the second stage. The results showed that cumulative hydrogen production slightly increased with the substrate to acid solution (2 % v/v H2SO4) ratio. The highest cumulative hydrogen produced (77.47 mL with 7.75 mL H2/gVS) at 1:40 substrate to acid solution, however the highest hydrogen content obtained at 1:20 (40.1 %). Hydrogen could not be produced from water hyacinth without acid pretreatment, only 4 mL hydrogen was detected from control case. In the second stage, methane was generated from the residue of first stage fermentation and found that the highest cumulative methane was obtained from 1:30 substrate to acid solution ratio. The methane content was not significantly different for control (53.68 %), 1:10 (54.45 %), 1:20 (53.46 %), and 1:30 (52.10 %) cases. The modified Gompertz, modified Logistic, and Cone model were best fit models for hydrogen production since the fermentation needed lag phase time before the hydrogen can be generated. The calculated lag phase time from modified Gompertz model increased from 0.0531 to 0.9775 day, and those from modified Logistic model increased from 0.3867 to 1.0305 day. On the other hand, the Cone model, first order model, and Transference function agreed very well with the second stage methane production data where lag phase time was nearly zero.
HIGHLIGHTS

Biohydrogen cannot be produced from water hyacinth without acid pretreatment
The optimum substrate to acid solution ratio for pretreating water hyacinth for hydrogen production is at 1:20 with highest hydrogen content. Higher acid ratio produced more undesired gases
Biomethane can be produced from water hyacinth without acid pretreatment. Only mechanical size reductionand heating pretreatment are enough to facilitate the process
Hydrogen production were best described by the modified Gompertz, modified Logistic, and Cone model. On the other hand, second stage biomethane production were best described by the Cone model, first order model, and Transference function
