Authors: Hoai Thu Pham , Huyen Trang Do-Thi , Linh Luu Canh , Duc Nguyen Minh 
Published: December 2023

AbstractPrimary hypertrophic osteoarthropathy (HOA) is a rare condition with no identifiable cause, accounting for 3%–5% of all HOA cases. It is challenging to identify incomplete primary HOA, which can be misdiagnosed as other hypertrophic periostitis diseases. At least two of the four criteria set by Borochowitz and Rimoin (1990) must be present to diagnose primary HOA. Diagnostic difficulties due to incomplete or atypical manifestations are common. We present a case of incomplete primary PHOA at Hanoi Medical University Hospital in Vietnam. A 37-year-old male presented with ankle joint pain for nearly four years. X-ray and magnetic resonance imaging showed periostitis in the tibias and fibulas, which could not exclude Camurati–Engelmann disease. Finally, gene sequencing on the Illumina MiSeq system identified a missense mutation (c.295C>T) in the solute carrier organic anion transporter family member 2A1 (SLCO2A1) gene on chromosome 3. Our case report and literature review aim to improve specialists' understanding of incomplete primary HOA and reduce the frequency of missed diagnoses.

CaMoO4- and SrMoO4-based scheelite-type phases are noteworthy functional materials, whose properties strongly correlate with their structure. This work is devoted to La- or Bi-doped scheelite-type molybdates. The purpose of the present study is to quantify the effect of isolated electron pairs of bismuth on the distortion of the structure and related properties. Conventional solid-state technology was used for the synthesis of (Ca/Sr)1–3xLa2xФxMoO4 and Sr1–3xBi2xФxMoO4, (0.025≤ x ≤ 0.275). The structure was investigated by X-ray powder diffraction and Raman spectroscopy. Rates of structure distortion were characterised by the analysis of the autocorrelation function (AAF) of Raman spectra. Energy gaps were calculated by the Kubelka-Munk method. The conductivity was studied with a.c. impedance spectroscopy. For (Ca/Sr)1−3x(Bi/La)2xФxMoO4 series 0.025 ≤ x ≤ 0.15 compositions show a basic defect scheelite structure, while 0.15 x ≤ 0.225 compositions of Bi-doped samples exhibit tetragonal supercells. The chemical compression of unit cell is more evident in the case of Bi-doping, indicating the preferred orientation of the isolated electron pairs. The distortion of MoO4 polyhedra showed by AAF was more significant for Sr1−3xBi2xФxMoO4 than for Sr1−3xLa2xФxMoO4, the Δcorr parameters for Bi-doped compositions were almost double in comparison with La-doped one in the range of 50–600 cm–1 of the Raman shift. The «critical» x = 0.15 point was also clearly indicated by Δcorr parameter. The AAF of the Raman spectra of solid oxides was shown to be a good tool for prediction of properties and points of phase transitions in solid oxides.

Authors: Biquan Mo Et al. 
Published: December 2023

Vocational Education readies students for specific careers and industries. A robust learning approach is crucial to meet modern workforce demands and foster knowledge exchange. This article introduces the origination of a Learning Model for Blended Collaborative Knowledge Construction in Vocational Education. This model merges methods from blended learning with collaborative strategies for constructing knowledge, fuelling student engagement, skills acquisition, and shared knowledge creation. The research utilizes the Delphi method to accumulate convincing proof for learning models prioritizing blended collaboration in knowledge generation. The sample pool comprises 60 students spanning two Zigong Vocational Training Institute classes, gathered via selective sampling. Data collection involved pre and post-testing of the student’s performance in the experimental and control groups, reinforced by the satisfaction survey from the experimental group. Data analysis employed statistical tools like percentages, means, standard deviations, and the t-test for related samples. The study found that pretest scores and SPSS data analysis showed that the f-test significant value is .702, which exceeds .05. This implies that, under the assumption of equal variance, the mean equivalence t-test findings for the first row of data, as shown in the table above, show that the experimental class averages 81.02 and the control class 81.05. The experimental and control groups' pretest scores are not significantly different, as the computed p-value of .984 is larger than .05. Thus, teaching practice is reasonable. The experimental group's student satisfaction measure averaged 4.27, ranging from 4.10 to 4.43, indicating that students are content with their academics. The control group's student satisfaction measure averaged 2.87, ranging from 2.50 to 3.10, indicating low satisfaction with learning. Students in a vocational education setting were compared using a hybrid collaborative knowledge creation learning model, demonstrating its potential to enhance student satisfaction and outcomes.

Machine learning with its vast framework is making its way into every aspect of modern society. The segment of betting sports particularly horse racing calls for the attention from a large spectrum of research community owing to its value to the stakeholders and the amount of money involved. Horse racing prediction is a complex problem as there are a large number of influencing variables. The present study aims to contribute in this domain by training machine learning algorithms for predicting horse racing results or outcomes. For this, data for a whole racing season from 2017 to 2019 of races conducted by Turf Club of India was considered which amounts to over 14,700 races. Six algorithms namely Logistic Regression, Random Forest, Naive Bayes, and k-Nearest Neighbors) k-NN were used to predict the winning horse for each race. Synthetic Minority Oversampling Technique (SMOTE) technique was applied to the imbalanced horse racing data set and the attributes of the horse race repository were analyzed. The results were compared with other sampling methods to evaluate the relative effectiveness of this method. The proposed framework is able to give an accuracy of 97.6% which is substantially higher when compared to other similar studies. The research can be beneficial to the stakeholders as well as researchers in the same area to do further analysis and experiments.

Laser based Optical Wireless Communication(OWC) is emerging as one of the key advancements for the 5G and beyond technologies. This technology provides high bandwidth, extremely high data rate and high speed communication due to the use of optical waves for data transmission in the field of wireless communication. The system performance is limited due to the presence of turbulence in the atmosphere.We have developed system model using log normal channel distribution in the weak to moderate atmospheric turbulence. Closed form of expression is derived which provides the channel capacity in the presence of weak turbulence using log normal distribution. Subcarrier Internsity Modulation (SIM) BPSK modulation technique is used in OWC system which provides bettter performance in terms of received BER as compared to NRZ – OOK modulation.

Authors: Shashank Srivastava Et al. 
Published: December 2023

Serverless computing, epitomized by AWS Lambda, has revolutionized application development and deployment by abstracting away server management and offering auto-scalability. AWS Lambda's 15-minute maximum timeout for function execution, however, presents a unique challenge for users aiming to process longer tasks within the serverless framework. In this paper, we dive deep into the execution dynamics of AWS Lambda within the AWS serverless environment, with a particular focus on extended execution times. As serverless computing gains traction, understanding the nuances and limitations of AWS Lambda's default settings becomes paramount.
This paper investigates different request handling mechanisms within AWS Lambda and presents empirical data to demystify the underlying processes. By addressing the challenges posed by long-running serverless functions, we aim to provide practical insights and potential solutions for developers and architects seeking to optimize their serverless applications. In the quest for efficient triggering mechanisms for extended serverless functions, this paper offers valuable guidance, empowering users to leverage AWS Lambda effectively while circumventing the default timeout constraints.

Published: December 2023

: For audiological prosthesis surgery morphometry of stapes is of utmost importance. Previous studies were mainly based on foreign and northern Indian population. Hence the present study.: To measure the morphometric parameters of stapes and compare the same with the previous studies.: This cross sectional observational study, performed on the ear ossicle, stapes obtained from 26 cadaveric heads. A total of (26 x 2) = 52 sets of stapes were taken out for the study. Measurements of various parameters of the ossicles were done with micrometer. Comparison among them with respect to sex, laterality and race were made. Age variation was not considered as the ossicles reach their full size at birth. Statistically significant difference in the total height of stapes was observed between male and female ossicles, but no such disparity was found between ossicles of the two sides. Height of stapes in males (mean: 3.35mm) was found to be significantly higher (p value: 0.00001) as compared to females (mean:3.18mm) in this present study. In surgeries for otosclerosis, the stapes superstructure is removed and replaced by a prosthetic ‘piston’, the selection of which is determined by the distance between the lenticular process of incus and the footplate of stapes, which in turn corresponds to the height of stapes superstructure. This measurement is vital for a properly fit piston and thus to the outcome of the surgery in terms of hearing improvement and lack of complications like expulsion of the piston, intractable vertigo, etc. When the mean values found in this study were compared with those of previous foreign and Indian studies, some of the values were found to be similar. : The height of stapes was shorter in our study as compared to studies based on North Indian population. These differences might point towards geographic or ethnic variations in the stapes which might call for further research work into this topic.

Published: December 2023

Appendicitis is one of the most common diseases that a surgeon faces in practice. Sometimes patients may present a few days after the onset of acute appendicitis with a palpable mass a phlegmon is a type of inflammatory tumour that consists of an inflamed appendix, as well as the larger omentum and associated viscera.To evaluate the need for interval appendicectomy in patients with appendicular lump. The study included all patients with an appendicular mass and was put on conservative management. . Failures of resolution of mass with conservative management were taken up for appendicectomy. The patients were discharged on successful conservative management and followed up at regular intervals for 12 months. Any patient with features suggesting recurrence of acute appendicitis on follow up was admitted and taken up for appendicectomy. All of the above information was gathered and statistically evaluated.Out of 58 cases of appendicular mass, 3 (5.17%) were operated due to failure of resolution of mass. The remaining 55 (94.83%) cases were successfully treated conservatively and followed up regularly for 12 months. 4 (7.27%) patients were lost to follow up. 1 (1.81%) patient revealed carcinoma of caecum and underwent right hemicolectomy. The remaining 50 (86.2%) cases, from which 42 (84%) patients remained recurrence free. 8 patients (16%) had recurrent appendicitis, out of which 7 (14%) patients underwent emergency appendicectomy, 1(2%) patient developed appendicular lump and was treated non operatively. In our study recurrence rate of acute appendicitis following resolution of appendicular mass is low (16%). So interval appendicectomy have to no longer be the rule in all patients after resolution of mass and should be reserved for patients with recurrences or with increased risk factors for recurrence.

In this study, we wanted to determine the incidence and prevalence of AKI in admitted patients of our institution in relation to their age, sex and clinical conditions. We also wanted to study the various aetiologies causing acute kidney injury in children, its severity in admitted patients, the time interval of onset of disease and onset of AKI, it’s mode of management and outcomes in children.This study was conducted in the paediatric ward of a tertiary care hospital in Eastern India. Total 147 cases of hospitalized AKI patients were studied.The incidence of AKI was found to be 1.27% in all hospitalized children. Maximum no. of cases were found in the age group &#62;10 years (44.2%). Male children outnumbered female children by a ratio of 2:1. Fever (72.8%) and Oliguria/anuria (72.1%) were the most common presenting features. Pallor was the most common presenting sign in 66% followed by oedema (42.2%), encephalopathy (31.9%) and respiratory distress (16.3%). 32% of cases presented within 24hrs with an H/O oliguria/anuria and 64% in within 72hrs. Most patients were managed with conservative management (53%) but 36.7% were managed with HD and 10.3% were managed with PD.Acute Kidney Injury cases were more common in children of age group &#62;10 years, males being affected more. Fever and oliguria/anuria were the commonest mode of presentations with malaria as the most frequent clinical condition associated with AKI followed by sepsis. The renal type was the commonest type of AKI. There was a moderate derangement of kidney function in the majority of cases with hyperkalaemia in a significant group of patients. 47% of patients required dialytic support and case fatality was 13%. The presence of dysnatremia, hyperkalaemia, encephalopathy and shock were poor predictors of the outcome of AKI.

Tuberculosis is an airborne infectious illness caused by Mycobacterium tuberculosis, and it is the most common cause of morbidity and mortality worldwide. Extra-pulmonary TB, often known as ocular tuberculosis, can occur alone or in conjunction with pulmonary tuberculosis. Tuberculosis of the eye can be caused by an active infection or a type 4 hypersensitivity reaction.Aim: To investigate the role of antituberculous therapy in the treatment of suspected intraocular tuberculosis. Based on a clinical diagnosis of Ocular tuberculosis, 46 patients were assessed with a chest X-ray, Mx test, and quantiferon gold assay and treated with ATT. The results showed that out of 46 patients, 29 were females and 17 were males. There were 34 patients with B/L involvement and 12 with U/L involvement. In addition, 76 percent of individuals tested positive for tuberculin on their skin, indicating latent tuberculosis. Quantiferon gold assay was positive in 19.56 percent of patients. On X-ray chest, 17.3% of patients had a healed old tuberculosis lesion. H/O contact with TB family members was reported in 13.04 percent of patients. All patients who had ATT therapy had a favourable outcome, with inflammation clearance and non-recurrence.
A case series of agenesis of the corpus callosum in children - Clinical and neuroimaging correlation with aspects of neuropathophysiology

Published: December 2023

The corpus callosum is the largest connective fiber between two hemispheres and a crucial structure for the integrated cerebral function of the normal brain. The study of agenesis of the corpus callosum (ACC) develops insights into neurodevelopmental delays and autism in children. This is a case series of eight children with ACC confirmed by a neuroimaging in a teaching hospital. The clinico-neuroradiological profile of ACC were studied retrospectively and reviewed clinical correlation with neuroradioimaging in the light of neuropathophysiology knowledge.The study group was appeared as nonsyndromic. Every subject had a normal chromosomal study by karyotyping. These ACC patients neither had a specific recognizable syndrome nor the constellation of malformations are indicative of a disorder. The mean age of subjects was 21.3 months, and no predilection for gender. The global developmental delay was the most common presentation found in seven ACC (87.5%) children. The second commonest, four ACC (50%) patients, was seizure. Two ACC (25%) had colpocephaly. Five ACC children (62.5%) had somatic anomalies; four ACC (50%) patients had cardiac defects.ACC children present a poor neurodevelopmental outcome. The extracallosal brain anomaly determines a worse neurological prognosis in nonsyndromic ACC. Grey matter heterotopia in neuroimaging was associated with seizure in ACC children. However, colpocephaly along with ACC may present with normal neurodevelopment. Hence, ACC in neuroimaging may have not predicted the final neurological outcome.ACC children with normal karyotyping may have somatic malformations. Moreover, echocardiography can be considered an initial routine screening in nonsyndromic ACC children.
