Authors: Thalia Nita
Published: November 2024

In the era of rapid development of information technology, deep learning, as the core driving force in the field of artificial intelligence, is leading profound changes in the education industry. Computational thinking, as a key ability to solve complex problems and design innovative systems, has become one of the important indicators to measure the comprehensive quality of college students. This paper focuses on the cultivation of college students’ computational thinking in the context of deep learning, and explores through empirical research how to effectively improve college students’ computational thinking ability in the current technological environment, as well as its impact and promotion on the cultivation of college students’ computational thinking. By designing and implementing an empirical study targeting students majoring in Electronic Information Engineering at Nanchang Normal University, this study aims to explore the actual effects of deep learning-based teaching models in enhancing college students’ computational thinking abilities. Students majoring in Electronic Information Engineering at Nanchang Normal University were selected as the research subjects. A questionnaire survey was conducted, which constructed nine dimensions including decomposition ability, abstract ability, modeling ability, algorithmic thinking, creativity, cooperation ability, iterative optimization, transfer ability and evaluation. These dimensions were found to have significant Pearson correlations at the 0.01 level (two-tailed). Further exploration of gender differences in each dimension revealed that there were significant differences between males and females in terms of decomposition ability, abstract ability, modeling ability, creativity, iterative optimization, transfer ability, and evaluation, with males having significantly higher average scores than females. However, no significant gender differences were observed in algorithmic thinking and cooperation ability. The study points out that deep learning technology provides a new perspective for computational thinking education, contributing to the cultivation of students’ innovative thinking and autonomous learning abilities. This research provides practical references and theoretical foundations for the teaching reform of electronic majors in universities.

Authors: Kalpana Rajendra Kulkarni  , Pradhan Monnaiah K  , Padma S  , Hema Viswanath K
Published: November 2024

Background: Perioperative anxiety adversely affects mental and physical well-being and it is associated with increased pain, stressor responses with general anesthesia (GA), and nausea-vomiting leading to delayed recovery. Recent studies have proven melatonin and gabapentin provide sedation, anxiolysis, and reduced pressure responses.
Aims and Objectives: This study aimed to compare melatonin and gabapentin as premedication for anxiolysis and attenuation of hemodynamic response to GA. Post-operative pain and sedation were also compared.
Materials and Methods: A total of 99 subjects (n=33 in each group) between 18 and 60 year of age, ASA I/II scheduled for elective abdominal surgeries of < 3h under GA were included in the study. Patients in Group A were administered melatonin (10 mg×2 tab.), those in Group B were administered gabapentin (400 mg×2 tabs), and those in control Group C were treated with Vitamin C (500 mg×2) before 2 h of surgery. At 0 min, 30 min, and 60 min assessments of anxiety, sedation, cognition, psychomotor function, and orientation were done.
Results: There were significantly low anxiety scores in Groups M and G compared to Group C at 60 min and 90 min (P=0.0000). Sedation score was significantly less in Group C patients compared to Group M and G at 30 min (P=0.0008), 60 min, and 90 min (P=0.0000) intervals. Heart rate and mean arterial pressure were increased in Group C patients as compared to Groups M and G.
Conclusion: This study showed that melatonin had more anxiolytic and less sedative action, so also cognitive functions and orientation were well preserved in melatonin-treated subjects than in gabapentin. Hemodynamic responses were comparable in melatonin- and gabapentin-treated patients.

Authors: Banerjee Siddhi , Halder Susanta Kumar , Banerjee Tibar , Das Debojyoti , Biswas Rajdeep , Chakraborty Soma , Saha Debasish
Published: November 2024

Background: Supraclavicular brachial plexus block (BPB) is being utilized extensively for upper limb surgeries. To improve block quality, several adjuvants have been used successfully. Fentanyl and dexmedetomidine has been evaluated as adjuvants for such block done using ropivacaine. However, block qualities have been modified to a variable extent with use of such adjuvants.
Aims and Objectives: Hence, the study was designed to compare fentanyl and dexmedetomidine as adjuvants during ropivacaine-induced supraclavicular BPB.
Materials and Methods: Sixty adults undergoing upper limb surgeries were randomly divided in to two groups to receive either fentanyl or dexmedetomidine as adjuvants to ropivacaine for supraclavicular BPB. The onset of sensory block was the primary outcome measure. Duration of sensory bloc, motor block characteristics, and adverse events were also evaluated.
Results: Considerably faster onset of sensory and motor blockade was found with the use of fentanyl as adjuvant over dexmedetomidine (sensory, 8.2±1.19 vs. 12.07±0.96, P<0.001; and motor, 7.0±0.43 vs. 30.43±1.41, P<0.001). However, the duration of sensory and motor blockade were found considerably prolonged with the use of fentanyl over dexmedetomidine.
Conclusion: Fentanyl can be a better alternative to dexmedetomidine as adjuvant to ropivacaine for supraclavicular BPB in view of faster onset of sensory and motor block. While prolonged duration of sensory block appears to be beneficial, the prolonged motor block can cause delay patient mobility.

Authors: Neha Khillar  , Rohith George  , Sathiqali AS  , Basil Ibrahim
Published: November 2024

Background: Pleural effusions are classified as exudate or transudate to guide clinical management. While Light’s criteria have been the standard for this differentiation due to their high sensitivity, their lower specificity can lead to potential misclassification of transudates as exudates. This study evaluates the clinical utility of pleural fluid cholesterol compared to Light’s criteria.
Aims and Objectives: The aim of the study was to assess the clinical utility of pleural fluid cholesterol as a laboratory parameter in differentiating exudate from transudate pleural effusions.
Materials and Methods: This cross-sectional study included 100 participants with pleural effusion. After baseline data collection and clinical examination, blood tests and pleural fluid analyses were conducted. McNemar’s test compared the sensitivity, specificity, and diagnostic accuracy of pleural fluid cholesterol with Light’s criteria.
Results: Light’s criteria showed a sensitivity of 98.39%, specificity of 84.21%, positive predictive value (PPV) of 91.04%, negative predictive value (NPV) of 96.97%, and diagnostic accuracy of 93%. Pleural fluid cholesterol (threshold >45 mg/dL) demonstrated a sensitivity of 91.94%, specificity of 97.37%, PPV of 98.28%, NPV of 88.10%, and diagnostic accuracy of 94%. The difference in specificity was statistically significant (P<0.05), while the difference in sensitivity was not. The overall diagnostic accuracy of pleural fluid cholesterol was similar to that of Light’s criteria.
Conclusion: Pleural fluid cholesterol has a higher specificity and similar diagnostic accuracy compared to Light’s criteria. It effectively identifies transudates, reduces false positives for exudates, and can serve as a simple test to confirm the type of pleural, potentially minimizing invasive procedures.

Authors: Lahiri Swati , Asim Kumar Kundu  , Manjushree Ray  , Rhituparna Bakshi
Published: November 2024

Background: Traditional interscalene brachial plexus block of C5 and C6 roots provides excellent anesthesia and analgesia for shoulder surgery and proximal humerus surgery, but frequently results in hemidiaphragmatic paresis. Superior trunk block (STB) along with local infiltration to supraclavicular nerve branches gives equal analgesic potency and distribution as interscalene brachial plexus block without affecting the phrenic nerve. The present study was carried out on 30 patients undergoing shoulder and proximal humerus surgery under STB of brachial plexus.
Aims and Objectives: This study was designed to evaluate the incidence of hemidiaphragmatic paralysis and minimum numerical rating scale (pain score) at rest in the post-anesthesia care unit, block duration, and patients’ satisfaction in patients receiving STB along with local infiltration to supraclavicular nerve branches.
Materials and Methods: Thirty patients undergoing shoulder and proximal humerus surgery between 18 and 80 years age group with the American Society of Anesthesiologists-Physical Status I-III of either sex were given ultrasound-guided STB (15 mL) along with a local infiltration (5 mL) superficial to scalenus medias muscle using 0.5% ropivacaine. Primary outcomes and secondary outcomes (patients’ satisfaction, block duration, and pain score) were recorded and analyzed by the Statistical Package for the Social Sciences version 26.
Results: Mean sensory block duration (hours) was 16.99±1.27 (95% confidence interval [16.51–17.47]). Incidence of hemidiaphragmatic palsy was minimum (3.3%). Post-operative analgesia was good as reflected by 28 (93.33%) patients having Visual Analog Scale score <3 at 24 h after completion of surgery. Patient satisfaction was also excellent (Likert scores 4 and 5 in 93.33% of patients).
Conclusion: STB along with local infiltration superficial to scalenus media’s muscle is associated with excellent intraoperative anesthesia and analgesia with minimal respiratory complication and remarkable patient satisfaction.
Comparative study of intubating condition between rocuronium and vecuronium for endotracheal intubation in general anesthesia
Authors: Ganesh Choudhari  , Rahul Basavraj Swami  , Shiraj Shaikh
Published: November 2024

Background: Muscle relaxation in anesthesia serves two main purposes: Facilitating endotracheal intubation and achieving surgical relaxation. The period from the suppression of protective reflexes during induction to the completion of intubation is critical, with an increased risk of regurgitation. Ensuring a patent airway is fundamental to general anesthesia, commonly achieved through endotracheal intubation.
Aims and Objectives: This study aims to evaluate the onset time, tracheal intubation conditions, duration of action, and maintenance of anesthesia using vecuronium and rocuronium, monitored by train-of-four (TOF).
Materials and Methods: This double-blind, prospective, randomized study was conducted over 18 months on patients undergoing elective surgeries under general anesthesia at a tertiary hospital. Ethical committee approval and informed written consent from all participants were obtained. Patients were randomly assigned into two groups of 50 each.
Results: Demographic parameters between both groups were statistically insignificant (P>0.05). The mean onset time, defined as the interval between the end of muscle relaxant administration and completion of intubation, was 99.6±12.03 s in Group A (rocuronium) and 231.0±13.21 s in Group B (vecuronium), a statistically significant difference (P<0.001). Intubation conditions were excellent in 36 (72%) and good in 13 (26%) patients in Group A compared to excellent in 28 (56%) and good in 17 (34%) patients in Group B.
Conclusion: Rocuronium provides earlier excellent and good intubating conditions compared to vecuronium, with similar cardiovascular stability during and after intubation. Rocuronium’s rapid onset of action makes it more suitable for quick tracheal intubation in surgical patients under general anesthesia.

Authors: Nazimuddin Paik  , Chakraborty Soma , Mandal Sangita , Sarfraaz Rahman  , Sayantan Modak  , Chakraborty Arpan , Mandal Mohanchandra
Published: November 2024

Background: Although proper placement of nasogastric tube (NGT) is a simple procedure, it can turn into a tedious task in an anesthetized intubated patient due to the absence of propulsive movement of swallowing. Different techniques of NGT placement are in vogue in clinical practice with varying success rates. The effect of endotracheal tube (ETT) cuff deflation on the success rate of NGT placement has been evaluated only in one study, and the first-attempt success rate was reported to be not high (55%).
Aims and Objectives: This interventional study primarily aimed at comparing the success rates of proper placement of NGT in the first attempt between the ETT cuff inflated and deflated states.
Materials and Methods: The present study was carried out on 244 adults scheduled for abdominal surgeries requiring NGT insertion. Patients received NGT placement with either an ETT cuff inflated (Group A, n=122) or ETT cuff deflated (Group B, n=122). The success rate of correct placement of NGT in the first attempt was the primary outcome. Procedure time and adverse events were also evaluated.
Results: Considerably higher success rate of correct placement of NGT in the first attempt was noted with ETT cuff deflated over-inflated state (85.2% vs. 55.7%, P<0.001). A shorter procedure time was observed with ETT cuff deflated over an inflated state (16.8±7.0 vs. 38.1±27.33 P<0.001). Adverse events were comparable.
Conclusion: The higher success rate of correct NGT placement was observed with endotracheal cuff deflated state over cuff-inflated state. Faster placement of NGT was noted with endotracheal cuff deflated state.

Published: November 2024

Background: Lower respiratory tract infection (LRTI) is the most common infection causing significant mortality with a 3–5% death rate in adults. The emerging nature of antimicrobial resistance to pathogens makes its treatment more challenging and complicated for physicians.
Aims and Objectives: The study was designed to obtain a comprehensive insight into the microbial profile and resistance patterns of the isolated pathogens in LRTI in a tertiary care hospital in Kolkata.
Materials and Methods: The cross-sectional observational study was carried out in the Microbiology Department of N.R.S Medical College from January to December 2021. Specimens collected from 782 clinically suspected LRTI cases were processed as per standard laboratory protocol following clinical and laboratory standard Institute guidelines.
Results: Out of 782 respiratory samples, 47.83% showed significant bacterial growth. The major risk factor was found to be type II diabetes mellitus (47.44%) followed by chronic obstructive pulmonary disease (36.57%) and smoking (21.35%). 85.56% growth was monomicrobial and Gram-negative organisms (88.50%) predominated. Klebsiella pneumoniae (36.90%) was the most predominant Gram-negative bacilli followed by Pseudomonas aeruginosa (17.11%) and Acinetobacter species (13.90%). Staphylococcus aureus was the predominant Gram-positive isolate (7.49%). Gram-negative organisms showed the highest resistance to penicillin and cephalosporins, whereas the lowest resistance in carbapenems. Piperacillin/tazobactam and levofloxacin showed good susceptibility. Linezolid was the most susceptible antimicrobial followed by vancomycin in the case of Gram-positive organisms. Extended-spectrum β-lactamase was detected as the mechanism of resistance in 31.12% of cases and carbapenemase was detected in 19.64% of cases.
Conclusion: Increasing antimicrobial resistance and varied bacterial etiology make it necessary to develop appropriate antibiotic policy and implement antimicrobial stewardship for effective and prompt therapy.

Authors: Kannan Murugesan  , Ramachandran Paramasivam  , Hariharakrishnan Ramamoorthy  , Kannan Kumaresan
Published: November 2024

Background: Coronary artery disease (CAD) prevalence in young individuals is rising, particularly in South Asian populations. Carotid artery hemodynamic parameters and their relation with CAD have not been studied much in young patients.
Aims and Objectives: The aim of the study was to study the relationship between Carotid artery hemodynamic parameters, and CAD severity in young patients.
Materials and Methods: A cross-sectional and single-center study was conducted involving consecutive patients undergoing coronary angiography due to acute coronary syndrome and aged under 40. Carotid ultrasonography and Doppler were performed to assess Carotid artery hemodynamic parameters. Gensini and SYNTAX scores were used to evaluate the severity and complexity of CAD. A total of 136 patients were included in the study.
Results: The mean age was 36.24±4.030 years, with 92 males. CAD patients demonstrated significantly increased carotid intima-media thickness (CIMT) (0.730±0.157 vs. 0.488±0.09; P<0.001) and resistive index (RI) in the right internal carotid artery (RICA) (P=0.004). Carotid blood flow velocities were significantly reduced in CAD patients, including peak systolic velocity (PSV) in both the RICA and left ICA (LICA) (P<0.05) and end-diastolic velocity of the RICA (P=0.049). Mean SYNTAX 9.526±6.762 and mean Gensini 23.403±18.58. CIMT correlated significantly with CAD complexity in terms of vessels involved (P=0.036) and of SYNTAX score (P=0.046). CIMT, PSV RICA, PSV LICA, and RI RICA are the significant CAD predictors.
Conclusion: CIMT and Carotid artery hemodynamic parameters are valuable predictors of CAD occurrence, severity, and complexity even in young individuals, highlighting their clinical utility in risk assessment for this population.

Authors: Al-Rubaie Salwan F. Salman , Al-Azawi Maher K. Mahmood
Published: November 2024

Video steganography is a method for concealing information within a video without substantially changing its visual content. The utilization of high-definition videos has garnered considerable interest from industries. H.265/HEVC, the recent video coding technology, is a promising field for video steganography. In this paper, a high concealment capacity based on three chaotic maps for the HEVC video standard is proposed, where the confidential data will be encrypted using two chaotic maps and then concealed in randomly selected Discrete Cosine Transform (DCT) coefficients of Transform Blocks (TBs), which are also randomly chosen using one chaotic map. The technique used in the DCT domain to achieve superior embedding capacity at the same visual quality compared with the state-of-the-art schemes in the compressed domain, and the use of three novel chaotic maps to protect the secret information and get uncrackable security level are the significant contributions of this paper. The simulation findings proved that the proposed approach has an average concealing capacity reaching 41.3 Kbits/frame. This payload exceeds what recent cutting-edge techniques could achieve in 1280 x 720 video frame dimensions with a ) of -0.009 dB and a Bit Rate Increase (BRI) of 0.0747 at a Quantization Parameter (QP) value of 32. Furthermore, the critical space size of the suggested scheme is , which makes it very secure against all types of brute-force attacks.

Published: November 2024

Fibers are widely used in construction because they have mechanical and thermal properties that improve the properties of structures added to them. This paper addresses the improvements made to the compressed earth block (CEB) when palm fibers and glass are added. This block is made up of soil and cement. The fiber ratio varies between 0% and 0.4%, and a compressive force of 2.5 MPa is applied to the samples. The physical, mechanical, and thermal properties of the CEB are studied according to systematic criteria using a numerical simulation program to find out how heat is transferred inside the samples. Preliminary results showed that the addition of fibers reduces the bulk density value between 1.88% and 11%, increases the compressive strength between 14.28% and 28.85%, decreases the thermal conductivity value between 1.38% and 22.22%, and decreases specific heat observed by 19.34% and 25.77%. These results give a clear view of the changes in the CEB when fibers are added and how to improve some properties.

Published: November 2024

Significant changes have been made in the harvesting operations implemented within the oil palm industry. Mechanisation has replaced conventional manual harvesting methods, which are physically intensive work, leading to increased effectiveness. However, despite the known association of manual labour with musculoskeletal problems among workers, it remains crucial in harvesting operations. Electromyography (EMG) has emerged as an essential tool for monitoring muscle activities. This paper aimed to develop an Arduino-based EMG system for muscle activity monitoring in oil palm harvesters as a cost-effective and user-friendly method. The results showed that there was a direct correlation between recorded values and lifted loads, whereby 8kg had the highest reading while 2kg had the lowest reading. It reflects some positive trends in mean values in the weight categories found in the dataset, specifically 0.4238 for 2kg, 0.5078 for 4kg, and 0.7937 for 8kg. Similarly, standard deviations showed an increasing pattern with an increase in weight, indicating a trend for more variation at higher weights. The prototype demonstrated promising results regarding capturing muscle activities under various scenarios, which indicate its potential to assist in designing and developing ergonomically improved machines. Further research needs to be conducted to test the accuracy.

Community empowerment must be carried out continuously considering that changes occur all the time. Changes can be caused by government policies, economic conditions or changes in natural conditions. This has an impact on people's life patterns and follows these changes.        This training activity to foster creativity aims to help and provide assistance to rubber farming communities in overcoming economic disparities while waiting for the harvest period. This activity can encourage the emergence of creative thoughts/ideas to produce other products so that you can earn your own income without expecting continuous government assistance. It is hoped that this training can increase rubber farmers' innovation with their own capital.       The problem faced by rubber farmers is that they do not have the skills to fulfill their daily needs and while they wait for the harvest period. Therefore, the environment demands creativity and innovation with one's own capital. Through this training, it can open the thinking horizons of farming communities in opening up business opportunities with relatively small capital.  Keywords: Creativities, harvest period, self capital

Introduction: Osteoporosis and low bone mass affect millions of people worldwide, leading to severe consequences ranging from disability to mortality. This study aimed to determine the prevalence and risk factors of osteoporosis among postmenopausal women in a district of Nepal.Methods: An analytical cross-sectional study involving postmenopausal women from Nuwakot, Dhading, and Rasuwa districts in Nepal was conducted at Trishuli Hospital, Nuwakot. Ethical approval was taken from the Institutional Review Board of Nepal Health Research Council(Reference number: 1768). The prevalence of osteoporosis was determined, and the associated factors were analyzed using multivariate logistic regression. Dual-Energy X-ray Absorptiometry (GE-Lunar Prodigy) was used to measure Bone Mineral Density (g/cm2) at the proximal femur and lumbar spine. Various factors related to osteoporosis were also analyzed.Results: There were 384 postmenopausal women and the prevalence of osteoporosis was 82 (21.35%; 95% CI: 17.25%-25.45%)e. The mean age of female with osteoporosis was 67.52±8.84 years and that without osteoporosis was 55.70±7.69 years (p <0.001). The multivariate logistic regression showed aOR 0.82 for body mass index.Conclusions: The study reports a lower prevalence of osteoporosis than expected in postmenopausal women. There was a significant inverse relationship between osteoporosis and body mass index. However, no significant association was observed between Bone Mineral Density, biochemical variables, smoking, and parity.

Firearm injuries can result in varying degrees of trauma, depending on factors such as the type of firearm, range, and wound location. This case report presents the role of X-ray imaging in detecting a projectile causing fatal penetrating abdominal trauma in a 45-year-old male. The patient was found with a gunshot wound in his abdomen, and despite medical interventions, he succumbed to his injuries. X-ray imaging revealed a hyper-dense area resembling a bullet lodged in the abdominal cavity. Autopsy confirmed a close-range gunshot with significant internal damage to the peritoneum, mesentery, liver, and the bullet lodged near the L1 vertebra. This case underscores the value of radiological imaging in identifying projectile trajectory and injury severity, particularly in resource-limited settings. X-rays assist in distinguishing between penetrating and perforating wounds, aiding both forensic investigation and legal procedures. The integration of imaging in forensic autopsies improves the accuracy of injury assessment, especially in cases involving gunshot wounds.

Published: November 2024

Heat stress due to climate change has had a big effect on ecosystem systems, which affect the overall production of goats. Among all livestock species goats are considered more climates resilient. Area of interest for the researcher is to understand effect of high ambient temperatures on the overall health and production performance of goat. Increase in the average environmental temperature during the hot humid season can have a significant influence on the basic physiology of the rumen, thereby affecting the nutritional status of the animals. Goat species have browsing behavior to a changing climate than other ruminant species. They are the important source of income and as food to many poor and marginal farmers around the world. Goats are also the major means of employment and income source for women in rural areas. Source of income from goat sector mainly include milk, meat, manure, wool and skin. In the entire livestock animals, goat farming is more beneficial, compare to other farming, because it needs low resources and gives more income to farmers. Goat’s milk and meat protein is important feed supplement for rural communities. Goats have adaptation capacities to maintain their production under adverse climate conditions. They have excellent browsing behavior as well as an efficient digestion, allowing them to remain productive in difficult environmental circumstances. Due to these characteristics features goat breeding is vital to minimizing and adapting to the negative consequences of climate change.
