\"Balanced hyperosmolar therapy\" using 3% hypertonic saline - 20% mannitol versus an equiosmolar volume of either 3% hypertonic saline or mannitol 20% in supratentorial tumor resection: A new approach to achieve hemodynamic stability
Authors: Elkafrawy Samir A , Khames Mahmoud K , Kandeel Islam M 
Published: June 2021

Both 3% hypertonic saline (3% HTS) and 20% mannitol were proven to be effective in relaxing the brain during supratentorial surgeries. This work aimed to study the effect of consecutive use of both drugs on the brain relaxation score and hemodynamic status during such surgeries.Ninety patients scheduled for supratentorial brain surgeries included in this prospective, randomized and double-blind study. Patients were allocated in three groups; HTS group (n=30) received 3 ml/kg 3% NaCl infusion over 30 minutes, HTS/M group (n=30) received mannitol 20% (1.4 ml/kg) as an infusion over 15 minute followed by 1.5 ml/kg 3% NaCl infused over 15 minutes and M group (n=30) received 3.2 ml/kg mannitol 20% infusion over 30 minutes. Brain relaxation was estimated. MAP and serum Na level were recorded at baseline and then at 30, 90 and 150 min. Total fluid intake, total urine output and operative time were recorded. Fluid intake and urine output were the highest with 20% mannitol (p ˂ 0.001). HTS/M and HTS groups showed no significance when satisfactory and fairly brain relaxation scores were added (p=0.862). MAP and CVP were near to baseline in HTS/M group at 30 and 90 min, while at 150 min no significant difference between groups. Serum hyperosmolarity was noticed in all groups at all check points but maximally with HTS group at 30 min (321.1 mOsm/L). Balanced hyperosmolar therapy using 3% HTS and 20% mannitol consecutively resulted in a satisfactory brain relaxation and allowed more hemodynamic stability.

This study aims to compare the hemodynamic response of two commonly used induction agents Propofol and Etomidate in patients with left ventricular ejection fraction ≤40% undergoing Coronary Artery Bypass Grafting surgery. To compare the effects of Propofol and Etomidate on hemodynamics in terms of heart rate, rhythm, blood pressure, and central venous pressure. Narayana Multispeciality Hospital, Jaipur. Prospective, double-blinded, randomized, hospital based study.100 patients with LVEF≤40% scheduled for elective CABG, were randomly assigned to one of the two groups receiving either of the inducing agents, group A (PROPOFOL 2mg/kg) and group B (ETOMIDATE 0.2mg/kg). Unpaired t-test and Chi square test/Fisher exact test, p&#60;0.05 was taken as significant. HR, SBP, DBP and MAP decreased from post induction 1 min. to post induction 3 min. (fall greater in propofol, p&#62;0.005) then increased from post intubation 1 min. to post intubation 5 min. in both the groups (rise greater in etomidate group, p&#60;0.005). Need of drugs to control hypotension (62% and 26%, p=0.001) and to control pressor response (10% and 38%, p=0.002) was observed in both the groups. Etomidate is superior to propofol in providing hemodynamic stability before and after laryngoscopy and intubation, but less effective in controlling the pressor response to intubation. Therefore, Etomidate can be used as an induction agent with suitable adjuvants to control pressor response to tracheal intubation in patients undergoing CABG with low LVEF.
The effect of different doses of chloroprocaine 1% for low dose saddle anaesthesia in outpatient perianal surgery: A prospective randomized study
Authors: Jain Shweta 
Published: June 2021

The present study was designed to investigate saddle anesthesia with different doses of chloroprocaine at the same concentration (0.5%, w/v) in terms of extent of sensory and motor block, recovery from block, time for ambulation and time for urinary voiding. The study was conducted in the department of Anaesthesiology of a tertiary healthcare centre of southern Rajasthan. 120 patients of either sex, aged between 20-50 years, with American Society of Anaesthesiologists grade I/II scheduled for elective perianal surgery in lithotomy position (duration &#60; 40 minutes), were enrolled in the study. The patients were divided into three groups (n=40/group), receiving either 10mg, 15mg or 20mg of 1% 2-chloroprocaine in saddle anaesthesia. The effect was noted and compared in terms of extent of sensory and motor block, recovery from block, time for ambulation and time for urinary voiding. All the three groups were comparable with no statistical difference in terms of age, weight, height, BMI, ASA grading and site of injection among the participants of the groups. Number of patients who were able to move from stretcher to operation table and again from operation table to stretcher without help did not differ significantly among all the three groups. Similarly, there was no statistically significant difference in pre operative and post operative Bromage scores of participants among three groups (p value &#62; 0.05). There was significant difference in the number of anaesthetized dermatomes both pre and post operatively among all the three groups (p value &#60;0.001). Duration of surgery did not differ significantly among the three groups. There was also significant diference in the time for unassisted ambulation post operatively and time for urinary voiding among the three groups (p value &#60; 0.001). 10 mg chloroprocaine may cause early post operative pain while 30 mg dose may cause delayed unassisted ambulation and urinary voiding postoperatively so 15 mg dose can be used as minimum optimal dose for saddle anaesthesia for ultra-short perianal procedures.

Intraspecific diversity of durum wheat (Triticum durum Desf.): a unif ied classif ication
Authors: Lyapunova О. A. 
Published: June 2021

The Department of Wheat Genetic Resources of the All-Russian Research Institute of Plant Genetic Resources (VIR) had developed and published in 1979 a classification of the genus Triticum L., which is based on the genomic composition of species and the presence or absence of a number of main genes that govern the “classification” traits. The grounds have been laid by F. Körnicke and J. Percival, and supplemented by N.I. Vavilov and K.A. Flaksberger. The classification, which is most often referred to as the “Classification of Triticum by Dorofeev et al.”, belongs to a number of the main modern classifications of the genus. This is the world’s first standardized system that contains all known intraspecific (infraspecific) taxa of wild and cultivated wheat species. A detailed classification makes it possible to identify a wide variety of forms in the genus Triticum L. and its individual species, which is especially important for collections preserved in genetic seed banks. The use of the intraspecific classification of the genus Triticum L. greatly simplifies the identification of the VIR collection accessions introduced from various sources or checking accession identity after regeneration in the field. However, the direct use of such a voluminous classification meets several difficulties. Therefore, we propose a unified intraspecific classification of durum wheat, based on the description of only 16 main botanical varieties out of 131 described so far, which have complexes of morphological traits of the spike and kernel that occur most frequently in durum wheat collections. The remaining 115 botanical varieties, which have additional traits, get their name by the addition of the abbreviated Latin name of one or another additional trait to the main name. Having mastered this way of describing the morphological traits of accessions, any user can easily navigate oneself in the systematized intraspecific diversity of collections. The purpose of this work is to acquaint the reader with the intraspecific classification of durum wheat (Triticum durum Desf.) developed at VIR and to offer its simplified version, which is based on the identification of the main and additional morphological traits of the spike and kernel.

An overview of employment generation in the sectors of GHANA’S economy: Foreign direct investment perspective
Authors: Yeboah Evans , Kyeremeh Rose Gyamea 
Published: June 2021

As foreign direct investment (FDI) contributes to economic growth and development of the host country, it also serves as a basis of employment creation in an economy. Over the past years, FDI has helped accumulate capital for developmental projects in most developing and least developed countries. This study provides an overview of job creation through FDI inflow within the Ghanaian economy by considering the number of jobs allocated to the various sectors. The study makes use of a descriptive statistical method that quantitatively supports data analysis. The results show that as the total FDI registered projects decrease, the number of expected jobs to be created also declines. The outcome also revealed that the service sector enjoys a higher percentage of the FDI registered project and the total number of employments generated within the selected period. The result further indicates that about 84% of the aggregate jobs created were for Ghanaians. The outcome also showed that the tourism and export trade sectors’ performance towards job generation from FDI inflow is lower than other sectors of the economy. It is suggested that the government should continue to put in a great effort to make the country’s business environment much friendly for investors.

Keywords: FDI, employment, sectors, Ghana, economic growth, trade inflow.

Abstract
Purpose: Chronic mucocutaneous candidiasis (CMC) is characterized by persistent or recurrent fungal infections involving the nails, skin, oral and genital mucosa. Impaired IL17 mediated immunity is a cause for CMC. Patient and Methods: After the next-generation sequencing analysis showed the IL17RA variant, confirmation by Sanger sequencing was done. Functional validation of the variant by flow cytometry was performed. Results: We present a 6-year-old male patient who presented with recurrent oral and genital candida infections and eczema. He had staphylococcal skin lesions in addition to the fungal susceptibility and eczema. The patient was found to carry a previously unreported homozygous nonsense [(c.787C> T) (p.Arg263Ter)] mutation in the IL17RA gene. Sanger sequencing confirmed the variant and showed the segregation of the variant in the family. We used flow cytometry to detect IL17RA protein expression in patients’ PBMCs and measured the Th17 cell percentages. Severely decreased IL17RA protein expression was observed in patient’s PBMCs and decreased CD4+ IL17+ cell percentage as well as decreased IL17F expression in CD4+ cells compared with healthy control. Conclusion: In patients with chronic recurrent fungal and bacterial and/or infections of the skin, mucosa, and nails, advanced immunological studies should be performed to document the genetic susceptibility even if basic immunological tests are normal.

Published: June 2021

Abstract
The development of new electronics and communications technologies allows the Internet of Things (IoT) concepts to be put into practice. A large amount of information is expected to travel over the internet from intelligent objects to many different kinds of software and cloud computing applications. However, there are still several challenges to be overcome. Among them, management of devices energy consumption is intriguing. Therefore, a model to estimate the range of probabilities of the energy spent by IoT equipment is presented in this work. The results include the formulation of probability distributions and discrete event simulations. The proposed method can be applied to design and evaluate IoT applications.

Published: June 2021

Abstract
Background: Literature reports 5% of recurrence/ failure in pediatric accessory pathway ablations. Our aim was to investigate the reasons underlying this finding and share techniques to obtain long term success. Methods: Thirty-nine pediatric patients referred for a repeat procedure were analyzed: characteristics of the pathways and the initial and redo procedures were identified.Results: Mean age was 11.9 ± 3.3 years (59% males). Three patients (8%) had multiple accessory pathways. The most frequent location was left lateral (26%). Left sided pathway recurrence was caused mainly by poor contact (60%) and inadequate mapping (40%). For right lateral accessory pathways, poor contact accounted for 70% of failures. For antero-septal and para-hisian locations, the use of cryoablation and choice of low radiofrequency energy delivery accounted for > 75% of failures. Long-term success strategies included choice of contact force catheters and radiofrequency applications at the ventricular insertion of the pathway and in the aortic coronary cusps. In postero-septal substrates, the main reason accounting for failure was deep or epicardial location of the pathway (37%), solved by using an irrigated tip catheter or applying lesions within the coronary sinus, or applications from both right and left postero-septal areas. Conclusions: Acute failure and post-procedure recurrence in pediatric accessory pathway ablations have multiple reasons related to the characteristics of the pathway and the technology available. Accurate understanding of the anatomy, careful mapping and pacing maneuvers, and incorporation of new technologies contribute to achieve a definitive success in > 98% of procedures.
Development of the geometrical feature extraction tool using DBSCAN clustering for toolpath generation in incremental forming
Authors: Nagargoje Aniket , Kankar Pavan K. , Jain Prashant K. , Tandon Puneet 
Published: June 2021

Abstract
Incremental forming is an emerging manufacturing technique, which allows the forming of the components without product-specific dies. The process uses Computer Numerical Control (CNC) machine tools to form complicated geometries. A punch, mostly a ball end tool, follows the toolpath obtained from the 3D model of the desired geometry to deform a blank into the desired shape. The objective of the current research is to develop a geometrical feature extraction technology to generate the toolpaths for the incremental forming process. A novel geometrical feature extraction tool, developed using attribute clustering techniques is proposed here. The proposed technology extracts geometrical features from the sliced contoured data of the geometry using Density-Based Spatial Clustering of Applications with Noise (DBSCAN) clustering and convex hull algorithms. Initially, the DBSCAN clustering technique is used for parent feature extraction. Later, child features are extracted from the parent features with the help of a convex hull algorithm. This paper discusses in detail the algorithms developed to extract geometrical features. The performance of the developed algorithms is validated with three different multi-featured geometries representing different types of families like geometries with natural partitions (features are connected with edges), geometries with smoothly connected features, and free form geometries. The results show that the techniques work successfully with different complicated geometries to extract the features. The outcome of this research would help evolve a system for an automatic generation of the feature-based toolpaths for the incremental forming (and similar) processes.

Published: June 2021

Abstract
Purpose: To determine the corneal densitometry values by using Scheimpflug imaging in myopic, and hyperopic children and to compare the results with emmetropic children.Methods: The corneal densitometry measurements of the subject were obtained with Pentacam Scheimpflug tomography. The values were automatically measured in standardized grayscale units (GSU) over an area 12 mm in diameter, which was subdivided into 4 annular concentric zones (0-2 mm, 2-6 mm, 6-10 mm, 10-12 mm) and 3 corneal depths (anterior layer: anterior 120 µm; central layer: from 120 µm to the last 60 µm; posterior layer: last 60 µm). In addition, we evaluated the correlation between spherical equivalence and anterior corneal morphological parameters and the corneal densitometry values.Results: A total of 216 participants were included in this prospective cross-sectional study. The eyes were divided into three groups related to their spherical equivalent (SE) refractive error values as follows: 89 (41.2%) hyperopic eyes, 66 (30.6%) myopic eyes, and 61 (28.2%) emmetropic control eyes. The hyperopic eyes were found to have lower corneal densitometry values in 4 annular zones and the total diameter of all depths except the central layer. However, only the 6-10 mm annular zone of the central and posterior layers of the myopic eyes had lower corneal densitometry values than emmetropic eyes. There was also a significant correlation between spherical equivalence and corneal densitometry values in some zones of the hyperopic eyes. Conclusion: Backward scattering of light was lower in hyperopic eyes and this could affect the visual quality.
