Automatic diagnosis of COVID-19 with MCA-inspired TQWT-based classification of chest X-ray images.

In this era of Coronavirus disease 2019 (COVID-19), an accurate method of diagnosis with less diagnosis time and cost can effectively help in controlling the disease spread with the new variants taking birth from time to time. In order to achieve this, a two-dimensional (2D) tunable Q-wavelet transform (TQWT) based on a memristive crossbar array (MCA) is introduced in this work for the decomposition of chest X-ray images of two different datasets. TQWT has resulted in promising values of peak signal-to-noise ratio (PSNR) and structural similarity index measure (SSIM) at the optimum values of its parameters namely quality factor (Q) of 4, and oversampling rate (r) of 3 and at a decomposition level (J) of 2.

Assessment of core capacities for antimicrobial stewardship practices in indian hospitals: Report from a multicentric initiative of global health security agenda.

Introduction: Antimicrobial-resistant HAI (Healthcare associated infection) are a global challenge due to their impact on patient outcome. Implementation of antimicrobial stewardship programmes (AMSP) is needed at institutional and national levels. Assessment of core capacities for AMSP is an important starting point to initiate nationwide AMSP.

An Unusual Case of Appendiceal Carcinoid Tumor in a Child- Case Report.

Carcinoid tumors of the appendix are rare in children. They clinically present with features of acute appendicitis and are often diagnosed incidentally on the resected specimens. Local disease carries an excellent prognosis and simple appendicectomy suffices, whereas advanced cases need a right hemicolectomy.

Anaesthetic management of pulmonary stenosis already treated with pulmonary balloon valvuloplasty.

The presence of congenital valvular heart disease can pose a challenge to anaesthetists in paediatric patients planning for incidental surgeries. Most of the available case reports from various journals describe the anaesthetic management in adults, whereas, pulmonary stenosis can present anytime during childhood and adolescence. The present case-report highlights anaesthetic management in a 9-year-old child, who was diagnosed with severe pulmonary stenosis that was already treated with pulmonary balloon valvuloplasty, yet had an eventful perioperative period due to residual valvular dysfunction.

Effect of pretreatments on extraction of pigment from marigold flower.

Marigold flower (Tagetes erecta L) is one of the richest sources of xanthophylls. An enzymatic pretreatment method was developed for improved extraction of pigments from marigold flowers. Pretreatment with enzyme solution increased the diffusion coefficient from 1.

Laboratory evaluation of Ssp I PCR assay for the detection of Wuchereria bancrofti infection in Culex quinquefasciatus.

Background & Objectives: There is a need to delimit the areas of filariasis transmission in view of the Filariasis Elimination Programme launched in India. Infection rate in vectors is an important parameter in determining transmission and it is conventionally assessed by dissection and microscopy. A PCR assay based on Ssp I repeats of Wuchereria bancrofti has shown potential in the detection of infection in vectors.

Fulminant hepatitis in a tropical population: clinical course, cause, and early predictors of outcome.

The profiles of patients with fulminant hepatic failure (FHF) from developing countries have not been reported earlier. The current study was conducted prospectively, at a single tertiary care center in India, to document the demographic and clinical characteristics, natural course, and causative profile of patients with FHF as well as to define simple prognostic markers in these patients. Four hundred twenty-three consecutive patients with FHF admitted from January 1987 to June 1993 were included in the study.
