A Novel Fog Computing Approach for Minimization of Latency in Healthcare using Machine Learning

In the recent scenario, the most challenging requirements are to handle the massive generation of multimedia data from the Internet of Things (IoT) devices which becomes very difficult to handle only through the cloud. Fog computing technology emerges as an intelligent solution and uses a distributed environment to operate. The objective of the paper is latency minimization in e-healthcare through fog computing. Therefore, in IoT multimedia data transmission, the parameters such as transmission delay, network delay, and computation delay must be reduced as there is a high demand for healthcare multimedia analytics. Fog computing provides processing, storage, and analyze the data nearer to IoT and end-users to overcome the latency. In this paper, the novel Intelligent Multimedia Data Segregation (IMDS) scheme using Machine learning (k-fold random forest) is proposed in the fog computing environment that segregates the multimedia data and the model used to calculate total latency (transmission, computation, and network). With the simulated results, we achieved 92% as the classification accuracy of the model, an approximately 95% reduction in latency as compared with the pre-existing model, and improved the quality of services in e-healthcare

A study on clinical, etiological and laboratory profile in patients with jaundice at a tertiary care centre in south bihar

Introduction: Jaundice is a major components of the syndrome of liver failure, which can be acute, subacute or chronic. Subacute and chronic liver failure are well-recognized syndromes with known causes of liver disease. While viral hepatitis and acetaminophen overdose are major causes of acute liver failure, there are many other infections and non-infectious causes that can mimic this presentation especially in a tropical country like India. Aim and objective: To study the clinical profile, etiology and laboratory findings in different patients with jaundice. Methodology: An observational study was conducted in General Medicine department in Narayan Medical College and Hospital, Jamuhar. Total 100 patients were selected from OPD and IPD of Narayan medical college and hospital with jaundice being treated and fulfilled inclusion and exclusion criteria. The study was conducted between  Dec 2019 to June 2020. Result: Most common cause of jaundice came out to be viral hepatitis making a total of 60 cases (60%), with 23 cases of females (23%) and 37 cases of males (37%). Among the viral hepatitis the highest number of cases were of HEV (26%), followed by HBV (21%), HAV(16%) and HCV(1%). Next most common cause of jaundice came out to be Malaria (12%), Dengue (5%), and drug induced hepatitis (15%).Conclusion: Jaundice is very common disease with male predominance, varied etiology most common being viral hepatitis, Alcoholic liver diseases. Most common presentation is anorexia followed by myalgia, fatigue. Keywords: Jaundice, viral hepatitis, SGOT, SGPT

A study on the prevalence of helicobacter pylori infection by rapid urease test in patients undergoing upper gastro intestinal endoscopy for dyspepsia in a tertiary care hospital of Southern Bihar

Background:  The epidemiology of H.pylori is poorly understood and it is a major health issue in developing countries such as India. There is a high incidence of morbidity and mortality due to complications of H.pylori infection. Prevalence of H.pylori differs from country to country, as well as from region to region in the same country. Methods: This observational study was carried out in an outpatient department in a tertiary care hospital of Southern Bihar, and included 163 patients who presented with dyspepsia and fulfilled the criteria of the study and were willing to undergo upper gastrointestinal endoscopy. Result:There is a high prevalence of H.pylori in southern Bihar with significant incidence in the male population and most commonly associated with dyspeptic symptoms.Increased incidence of gastritis was found in RUT positive patients on endoscopic examination

Interstellar dehydrogenated PAH anions: vibrational spectra

Interstellar Polycyclic Aromatic Hydrocarbon (PAH) molecules exist in diverse forms depending on the local physical environment. Formation of ionized PAHs (anions and cations) is favourable in the extreme conditions of the ISM. Besides in their pure form, PAHs are also likely to exist in substituted forms; for example, PAHs with functional groups, dehydrogenated PAHs etc. A dehydrogenated PAH molecule might subsequently form fullerenes in the ISM as a result of ongoing chemical processes. This work presents a Density Functional Theory (DFT) calculation on dehydrogenated PAH anions to explore the infrared emission spectra of these molecules and discuss any possible contribution towards observed IR features in the ISM. The results suggest that dehydrogenated PAH anions might be significantly contributing to the 3.3 μm region. Spectroscopic features unique to dehydrogenated PAH anions are highlighted that may be used for their possible identification in the ISM. A comparison has also been made to see the size effect on spectra of these PAHs

Prospective study comparing early functional outcome and gait analysis in femoral neck fracture treated by cemented hemiarthroplasty using modified Hardinge approach and conventional posterior approach

Background: A prospective study was done to compare the outcomes of management of fracture neck of femur by cemented hemiarthroplasty using modified Hardinge approach and conventional posterior approachMethods: The 2019 to 2022 50 patients underwent bipolar hemiarthroplasty for femoral neck fracture. Group A (Femoral neck fracture treated using conventional posterior approach) and group B (Femoral neck fracture treated using modified Hardinge approach) with 25 patients in each group. Outcomes were evaluated based on mean surgical time and Harris hip score and SF-36.Results: Mean duration of surgery in minutes was more for modified Hardinge approach. Harris hip score with standard deviation for modified Hardinge Approach for follow-ups was better and statistically significant than posterior approach. Similarly, quality of life after surgery, in terms of mean SF-36 score with standard deviation for modified Hardinge approach was better and statistically significant than posterior approach. Modified Hardinge approach has fewer complications in comparison to the posterior approach. With the advantages comes a longer learning curve to operate without complications. Hence, with proper surgical technique, and proper tight closure, we prefer the modified Hardinge approach over other approaches as it had nil dislocations and abductor lurch.Conclusions: Modified Hardinge approach for hip arthroplasty in elderly people with femoral neck fracture provide significant benefit in the early post operative period when compared to conventional posterior approach in terms of post operative pain, time of recovery, dislocation rate and quality of life

A Review on Different Techniques of Mutual Coupling Reduction Between Elements of Any MIMO Antenna. Part 2: Metamaterials and Many More

This two‐part article presents a review of different techniques of mutual coupling (MC) reduction. MC reduction is a primary concern while designing a compact multiple‐input‐multiple‐output (MIMO) antenna where the separation between the antennas is less than λ0/2, that is, half of the free‐space wavelength. The negative permittivity and permeability of artificially created materials/structures (Metamaterials) significantly help reduce MC among narrow‐band compact MIMO antenna design elements. In this part two of the review paper, we will discuss techniques: Metamaterials; Split‐Ring‐Resonator; Complementary‐Split‐Ring‐Resonator; Frequency Selective Surface, Metasurface, Electromagnetic Band Gap structure, Decoupling and Matching network, Neutralization line, Cloaking Structures, Shorting vias and pins and few more

Recurrent extraventricular anaplastic ependymoma with scalp metastasis

Extraneural metastasis from anaplastic ependymoma is uncommon. In a study from Memorial Sloan Kettering Cancer Center where the authors reviewed 81 ependymomas cases (between 1956 and 1989) there were only five (6.2%) cases had extraneural metastases. We present a case of anaplastic ependymoma with scalp metastasis and discuss the possible mechanism of spread. In majority most of the cases of metastatic extracranial ependymoma patients have underlying progressive intracranial disease. Although these patients receive standard treatment for the primary tumor (Gross total resection and radiotherapy) and the management options for recurrences includes re-excision, focal re-irradiation, stereotactic radiosurgery, or craniospinal radiotherapy for metastatic disease the long term outcome is not favorable

Giant high occipital encephalocele

Encephaloceles are rare embryological mesenchymal developmental anomalies resulting from inappropriate ossification in skull through with herniation of intracranial contents of the sac. Encephaloceles are classified based on location of the osseous defect and contents of sac. Convexity encephalocele with osseous defect in occipital bone is called occipital encephalocele. Giant occipital encephaloceles can be sometimes larger than the size of baby skull itself and they pose a great surgical challenge. Occipital encephaloceles (OE) are further classified as high OE when defect is only in occipital bone above the foramen magnum, low OE when involving occipital bone and foramen magnum and occipito-cervical when there involvement of occipital bone, foramen magnum and posterior upper neural arches. Chiari III malformation can be associated with high or low occipital encephaloceles. Pre-operatively, it is essential to know the size of the sac, contents of the sac, relation to the adjacent structures, presence or absence of venous sinuses/vascular structures and osseous defect size. Sometimes it becomes imperative to perform both CT and MRI for the necessary information. Volume rendered CT images can depict the relation of osseous defect to foramen magnum and provide information about upper neural arches which is necessary in classifying these lesions
