Background: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus that causes coronavirus disease 2019 (COVID-19) is a serious global health concern. The severity of the disease can be determined by serologic indicators such as C-reactive protein, lactate dehydrogenase, D-dimer, ferritin, and interleukin-6. (IL-6). Patients with preexisting conditions such as respiratory, cardiovascular, and pulmonary disease could be at risk of adverse outcomes. It is crucial to provide adequate medical care to manage these patients and increase their chances of survival. Aim: The study examined the impact of comorbidity and inflammatory markers on the severity and mortality of hospitalised COVID-19 patients. Materials and Methods: This retrospective study included 101 COVID-19 patients who had comorbidities and were hospitalised from April 2021 to April 2022. Results: Patients with a severe COVID-19 infection could be anticipated to have higher levels of inflammatory markers in their blood. Patients with chronic kidney and coronary artery disease have a worse prognosis than those with other comorbidities (P value

AbstractThis study explores the role of perceived customer value and loyalty relationships in mobile wallet (M-wallet). The study further investigates trust and satisfaction as drivers of loyalty and examines the role of trust in the traditional value-satisfaction-loyalty relationship. A total of 214 responses from M-wallet users were captured using a structured questionnaire in a cross-sectional survey design. The data collected was analyzed with the help of structural equation modeling. Trust and satisfaction in M-wallet are both found to be mediating the perceived customer value and loyalty relationship. Furthermore, results also confirm the sequential mediation impact of trust and satisfaction between the perceived customer value and loyalty relationship. The findings help practitioners in tailoring their customer relationship strategies to promote M-wallet loyalty. Finally, this study recommends that managers should emphasize leveraging trust and satisfaction to shape loyalty in addition to customer value. They should focus on initiatives to win trust, satisfy the customers, and enhance long-term customer relationships.

Introduction The effects of COVID-19 infection persist beyond the active phase. Comprehensive description and analysis of the post COVID sequelae in various population groups are critical to minimise the long-term morbidity and mortality associated with COVID-19. This analysis was conducted with an objective to estimate the frequency of post COVID sequelae and subsequently, design a framework for holistic management of post COVID morbidities.Methods Follow-up data collected as part of a registry-based observational study in 31 hospitals across India since September 2020–October 2022 were used for analysis. All consenting hospitalised patients with COVID-19 are telephonically followed up for up to 1 year post-discharge, using a prestructured form focused on symptom reporting.Results Dyspnoea, fatigue and mental health issues were reported among 18.6%, 10.5% and 9.3% of the 8042 participants at first follow-up of 30–60 days post-discharge, respectively, which reduced to 11.9%, 6.6% and 9%, respectively, at 1-year follow-up in 2192 participants. Patients who died within 90 days post-discharge were significantly older (adjusted OR (aOR): 1.02, 95% CI: 1.01, 1.03), with at least one comorbidity (aOR: 1.76, 95% CI: 1.31, 2.35), and a higher proportion had required intensive care unit admission during the initial hospitalisation due to COVID-19 (aOR: 1.49, 95% CI: 1.08, 2.06) and were discharged at WHO ordinal scale 6–7 (aOR: 49.13 95% CI: 25.43, 94.92). Anti-SARS-CoV-2 vaccination (at least one dose) was protective against such post-discharge mortality (aOR: 0.19, 95% CI: 0.01, 0.03).Conclusion Hospitalised patients with COVID-19 experience a variety of long-term sequelae after discharge from hospitals which persists although in reduced proportions until 12 months post-discharge. Developing a holistic management framework with engagement of care outreach workers as well as teleconsultation is a way forward in effective management of post COVID morbidities as well as reducing mortality.

Cognitive Radio Ad-hoc Networks (CRAHNs) combines characteristics of ad-hoc networks with cognitive radios to facilitate a variety of communication scenarios. However, these networks are subject to persistent attacks from internal and external adversaries, such as Masquerading, Spoofing, Spying, and Distributed Denial of Service (DDoS). Existing deep learning models proposed to counter these attacks suffer from complexity, real-time processing limitations, and a lack of network scalability. In addition, their limited IP tracing capabilities make them unsuitable for real-time deployments. To address these issues, this paper proposes a novel blockchain-based model for deep traffic pattern analysis and mitigation of malicious attacks in CRAHNs. The proposed model employs a multi-step methodology. The collected traffic patterns are then used to train a deep Convolutional Neural Network (dCNN) model. This trained model permits the temporal classification of incoming real-time traffic packets. The packets are stored on a distributed network based on blockchain technology to ensure data integrity, transparency, and traceability. This blockchain implementation renders the packets immutable and easily accessible, while also facilitating the recommendation of improved mitigation strategies. The blockchain employs a Proof-of-Trust (PoT) consensus mechanism and is managed via a Genetic Algorithm (GA)-based sidechaining model, which significantly reduces access and writing delays for various packets. The proposed model achieves a significant reduction in communication delay in comparison to existing models, with decreases of 35.4%, 19.5%, and 23.5% for BIDS, BIST WM, and GAN, respectively. Additionally, energy consumption is reduced by 18.5%, 18.3%, and 24.5%, respectively. In addition, the model exhibits an increase in throughput of 14.5%, 16.4%, and 15.5%, respectively. Lastly, it improves the accuracy of attack detection during various communications by 8.3%, 23.2%, and 8.3%, respectively. This paper presents a promising solution for enhancing the security of CRAHNs by providing a robust defense against malicious attacks and real-time protection for dynamic ad hoc networks. The integration of deep learning, blockchain technology, and optimization techniques results in significant improvements in performance metrics, demonstrating the potential of the proposed model for ensuring the security and integrity of CRAHNs.

Background: Patients infected with COVID-19 admitted to the intensive care unit (ICU) may have a higher incidence of developing secondary infections. These infections can further deteriorate the hospital course and increase mortality. Therefore, the objectives of this study were to investigate the incidence, associated risk factors, outcomes, and pathogens associated with secondary bacterial infections in critically ill patients with COVID-19. Methods: All adult COVID-19 patients admitted to the intensive care unit requiring mechanical ventilation from October 1, 2020 until December 31, 2021 were screened for inclusion in the study. A total of 86 patients were screened and 65 who met the inclusion criteria were prospectively entered into a customized electronic database. The database was then retrospectively analyzed to investigate secondary bacterial infections. Results: Of the 65 patients included, 41.54% acquired at least one of the studied secondary bacterial infections during the course of their ICU stay. The most common secondary infection (59.26%) seen was hospital-acquired pneumonia followed by acquired bacteremia of unknown origin (25.92%) and catheter-related sepsis (14.81%). Diabetes mellitus (P =

Objectives: This study was conducted to compare the disease severity of COVID-19 in pregnant and nonpregnant females of reproductive age group and to evaluate the effect of COVID-19 on neonatal outcome. Materials and Methods: The present prospective observational study was conducted at a tertiary care center in northern India over a period of 6 months. Females of reproductive age group (15–44 years) that were admitted in COVID isolation ward with reverse transcription–polymerase chain reaction-positive COVID-19 disease were included in the study and followed till discharge. Results: Among the 60 females of reproductive age group, 41.67% (25) were pregnant and 58.34% (35) were nonpregnant. The median duration of hospitalization among pregnant and nonpregnant females was 9 and 8.5 days, respectively. The severity of infection among pregnant and nonpregnant females was as follows: asymptomatic + mild disease 96% (24) and 77.14% (27) and moderate + severe disease 4% (1) and 22.86% (8), respectively. There were no maternal mortalities. Forty percent (10) of pregnant females had lower segment cesarean section (LSCS) and 32% (8) had normal vaginal delivery. There were 8 preterm, 6 full-term, 3 early-term, and 1 late-term deliveries. Twelve newborns had normal birth weight, 4 were low birth weight (LBW), 1 was very LBW, and 2 intrauterine deaths IUD were reported. No case of neonatal death or neonatal asphyxia was reported. Conclusion: In comparison to nonpregnant women with COVID-19 pneumonia, the infected pregnant females had mild or no respiratory symptoms, and none developed severe respiratory compromise or required intensive care. Preterm delivery, LSCS, and LBW were common in COVID-19-infected females.

Purpose: Early diagnosis of extrapulmonary tuberculosis (TB) with simultaneous detection of rifampicin (RIF) resistance (RR) directly from the sample is a revolution brought by GeneXpert Mycobacterium TB (MTB/RIF) assay. Line probe assay (LPA) is not recommended for extrapulmonary/nonsputum specimens; GeneXpert MTB/RIF provides a diagnostic option for these. Hence, the following study aimed to evaluate the performance of GeneXpert MTB/RIF assay in nonsputum samples. Materials and Methods: A total number of 642 extrapulmonary and nonsputum respiratory samples were subjected to Ziehl–Neelsen (ZN) staining technique, fluorescent microscopy (FM), and GeneXpert MTB/RIF Assay. All samples were cultured on a solid Lowenstein–Jensen (LJ) medium and culture-positive samples were subjected to GenoType MTBDRplus LPA and drug susceptibility testing by 1% proportion method on a solid LJ medium. Results: GeneXpert MTB/RIF assay detected MTB in 25.9% (166/642) of the samples. Sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of ZN staining technique and FM were 21.52%, 99.35%, 91.89%, and 78.77% and 27.22%, 99.78%, 97.73%, and 80.07%, respectively. Sensitivity, specificity, PPV, and NPV of GeneXpert MTB/RIF in the detection of MTB were 93.75%, 96.53%, 90.36%, and 97.80%, and RIF RR was 92.0%, 97.74%, 88.46%, and 98.48%, respectively. LPA performed on positive culture growth showed 100% sensitivity and specificity in the detection of RIF and isoniazid resistance. Conclusion: GeneXpert MTB/RIF showed high sensitivity and specificity in detecting MTB and simultaneous RIF RR among the nonsputum samples which had a good concordance to LPA. It provides a judicious option for early detection of multidrug-resistant TB in extrapulmonary and nonsputum respiratory samples.

The focus of cloud computing nowadays has been reshaping the digital epoch, in which clients now face serious concerns about the security and privacy of their data hosted in the cloud, as well as increasingly sophisticated and frequent cyberattacks. Therefore, it has become imperative for both individuals and organizations to implement a robust intrusion detection system (IDS) capable of monitoring packets in the network, distinguishing between benign and malicious behavior, and detecting the type of attacks. IDS based on ML are efficient and precise in spotting network threats. Yet, for large dimensional data sizes, the performance of these systems decreases. Thus, it is critical to building a suitable feature selection approach that selects necessary features without having an impact on the classification process or causing information loss. Furthermore, training ML models on unbalanced datasets show a rising false positive rate (FPR) and a lowering detection rate (DR). In this paper, we present an improved cloud IDS designed by incorporating the synthetic minority over-sampling technique (SMOTE) to address the imbalanced data issue, and for feature selection, we propose to use a hybrid approach that includes three techniques: information gain (IG), chi-square (CS), and particle swarm optimization (PSO). Finally, the random forest (RF) model is utilized for detecting and classifying various types of attacks. The suggested system has been verified by the UNSW-NB15 and Kyoto datasets, achieving accuracies of over 98% and 99% in the multi-class classification scenario, respectively. It was noticed that an intrusion detection system with fewer informative features would operate more effectively. The simulation results significantly outperform other methodologies proposed in the related work in terms of different evaluation metrics.

Abstract Background Increased occurrence of mucormycosis during the second wave of COVID-19 pandemic in early 2021 in India prompted us to undertake a multi-site case–control investigation. The objectives were to examine the monthly trend of COVID-19 Associated Mucormycosis (CAM) cases among in-patients and to identify factors associated with development of CAM. Methods Eleven study sites were involved across India; archived records since 1st January 2021 till 30th September 2021 were used for trend analysis. The cases and controls were enrolled during 15th June 2021 to 30th September 2021. Data were collected using a semi-structured questionnaire. Among 1211 enrolled participants, 336 were CAM cases and 875 were COVID-19 positive non-mucormycosis controls. Results CAM-case admissions reached their peak in May 2021 like a satellite epidemic after a month of in-patient admission peak recorded due to COVID-19. The odds of developing CAM increased with the history of working in a dusty environment (adjusted odds ratio; aOR 3.24, 95% CI 1.34, 7.82), diabetes mellitus (aOR: 31.83, 95% CI 13.96, 72.63), longer duration of hospital stay (aOR: 1.06, 95% CI 1.02, 1.11) and use of methylprednisolone (aOR: 2.71, 95% CI 1.37, 5.37) following adjustment for age, gender, occupation, education, type of houses used for living, requirement of ventilatory support and route of steroid administration. Higher proportion of CAM cases required supplemental oxygen compared to the controls; use of non-rebreather mask (NRBM) was associated as a protective factor against mucormycosis compared to face masks (aOR: 0.18, 95% CI 0.08, 0.41). Genomic sequencing of archived respiratory samples revealed similar occurrences of Delta and Delta derivates of SARS-CoV-2 infection in both cases and controls. Conclusions Appropriate management of hyperglycemia, judicious use of steroids and use of NRBM during oxygen supplementation among COVID-19 patients have the potential to reduce the risk of occurrence of mucormycosis. Avoiding exposure to dusty environment would add to such prevention efforts.

Introduction: Lung cancer is one of the most common malignancies to occur worldwide. Two main subtypes of lung cancer include small cell lung cancer and Non Small Cell Lung Cancer (NSCLC). Patients with advanced stage NSCLC who achieve good response with Tyrosine Kinase Inhibitors (TKI) have been found to have Epidermal Growth Factor Receptor (EGFR) mutation. The first biomarker identified for targeted treatment in lung cancer was EGFR and patients of NSCLC with EGFR mutation have superior survival outcome when treated with targeted therapy as compared to conventional chemotherapy. Aim: To compare the outcome of targeted therapy to mutation to EGFR and conventional therapy in non mutant lung cancer patient of NSCLC. Materials and Methods: The present longitudinal study was conducted in the Department of TB and Respiratory Diseases, Jawaharlal Nehru Medical College and Hospital, Aligarh, Uttar Pradesh, India from July 2017 to November 2019 on a sample size of 80. Patients diagnosed with NSCLC and EGFR mutation status were included in the study. They were started on TKI if tumour was EGFR positive and on conventional chemotherapy (cisplatin plus paclitaxel) if no mutation was detected on histopathology. Among the study group, 35 patients were EGFR positive and started on geftinib (group I), 45 were EGFR negative and received platinum-based chemotherapy (group II). Outcomes were measured in terms of progression-free survival, Overall Survival (OS), and toxicities. Statistical analysis of data was done using Statistical Package for the Social Sciences (SPSS) version 20.0. Results: Among the study group, 35 patients were EGFR positive and started on geftinib (Group I), 45 were EGFR negative and received platinum-based chemotherapy (group II). The mean age of EGFR positive patients was 58.91 years and for EGFR negative patients was 60.11 years. In group I, there was no complete response while 28.5% had partial response, 45.5% had stable disease and 25.7% had progressive disease. In group II, 15.5% patients had complete response, 33.3% had partial response,17.7% had stable disease and 33.3% had progressive disease. Mean progression-free survival in group I (5.65 months) was significantly higher than group II (4.26 months). The mean OS in group I (7.85 months) was slightly higher than group II (6.72 months). Both haematological and non haemaotlogical toxicities were significantly higher in group II. Conclusion: Patients with EGFR positive expression subjected to Gefitinib had significant mean progression-free survival with an acceptable range of non haematological toxicities and no haematological toxicities, as compared to the EGFR negative patients on conventional chemotherapy.

Background: Asthma is coined as a chronic inflammatory disorder and disarrays of the airways and respiratory tract which manifests as recurrent episodes of wheezing, breathlessness, chest tightness, and cough. The World Health Organization recognizes asthma as a major health problem. Although asthma can occur at any age, children and young adults are the age groups which are affected more commonly. Objectives: The objective of this study is to find the prevalence of bronchial asthma in school-going children (6–16 years) and its associated factors. Materials and Methods: A cross-sectional study among the school-going children in the age group of 6–16 years was done in the field practice areas of urban health and training center and rural health and training center of the Department of Community Medicine, JNMCH, A. M. U., Aligarh, U.P. the study done for a period of one year. The validated questionnaire (International Study on Allergy and Asthma in Childhood) was used. The sample size was taken as 902. The data were entered and analyzed in the SPSS statistical software version 20.0. Chi-square was used. Results: The prevalence of asthma among the study population was found to be 26.9%. Family history of smoking and history of allergy in an individual came out to be a significant factor associated with asthma. The association is also significant between asthma and the diet of an individual. Conclusions: Asthma among school children is a public health problem in urban and rural areas. There was a rising pattern in the prevalence of asthma at national and subnational levels.

Background: The current gold-standard therapies for chronic obstructive pulmonary disease (COPD) lack disease-modifying potential and exert adverse side effects. Moreover, COPD patients are at a higher risk of severe outcomes if they get infected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus, the cause of the current epidemic. This is the first study to document clinical research on an adaptogenic and steroidal activity–containing herb as a complementary medicine for COPD treatment.Objective: We aimed to evaluate the efficacy of Withania somnifera (L.) Dunal [Solanaceae] (WS) as an add-on therapy for COPD patients.Methods: A randomized, placebo-controlled, and double-blind clinical study was conducted. A total of 150 patients were randomly assigned to three groups: control, placebo, and WS group. In addition to conventional medicines, WS root capsules or starch capsules were given twice a day to the WS group and the placebo group, respectively. Their lung functioning, quality of life, exercise tolerance, systemic oxidative stress (OS), and systemic inflammation were assessed before and after 12 weeks of intervention. WS root phytochemicals were identified by LC-ESI-MS. The inhibitory activity of these phytochemicals against angiotensin-converting enzyme 2 (ACE-2); the SARS-CoV-2 receptor; myeloperoxidase (MPO); and interleukin-6 (IL-6) was evaluated by in silico docking to investigate the mechanism of action of WS.Results: The pulmonary functioning, quality of life, and exercise tolerance improved, and inflammation reduced notably the most in the WS group. Systemic oxidative stress subsided significantly only in the WS group. Although a minor placebo effect was observed in the SGRQ test, but it was not present in other tests. Withanolides found in the WS roots demonstrated substantial inhibitory activity against the proteins ACE-2, MPO, and IL-6, compared to that of a standard drug or known inhibitor. Moreover, FEV1% predicted had significant correlation with systemic antioxidative status (positive correlation) and malondialdehyde (MDA, negative correlation), suggesting that the antioxidative potential of WS has significant contribution to improving lung functioning.Conclusion: Our study clinically demonstrated that WS root when given along with conventional drugs ameliorated COPD significantly more in comparison to the conventional drugs alone, in GOLD 2 and 3 categories of COPD patients. In silico, it has potent inhibitory activity against SARS-CoV-2 receptor, ACE-2, MPO, and IL-6.

Pancreaticopleural fistula is one of the rarest complication of acute pancreatitis, chronic pancreatitis and pancreatic pseudocyst. Diagnosis requires a high index of clinical suspicion in alcoholic patients presenting with pancreatitis and associated recurrent pleural effusion. Diagnosis is delayed as patients usually present with predominant pulmonary symptoms of dyspnea and chest pain. Hereby authors presented a case, where a 50-year-old chronic alcoholic male presented with chief complains of shortness of breath and chest pain. Based on the chest radiograph, Computed Tomography (CT) scan and pleural fluid analysis diagnosis of pancreaticopleural fistula was made. The patient was managed with intercoastal tube drainage and symptomatic treatment for other complains. Medical management, endoscopic and surgical interventions bring out a good prognosis in pancreaticopleural fistula.

INTRODUCTION: Allergic rhinitis and bronchial asthma are thought to be sequela of the same allergic airway disease. The relationship between both diseases has been confirmed by various clinicopathological epidemiological and immunological studies. In this study, we tried to establish a different relationship between both diseases and strengthen the concept of “One-airway one disease.” MATERIALS AND METHODS: A total of 100 patients visiting ear, nose, and throat and respiratory medicine outpatient department were taken. They were divided into two groups of fifty each and were studied for various mediators of inflammation. Group 1 consisted of patients of allergic rhinitis and Group 2 consisted of patients of bronchial asthma. RESULTS: Most of the patients in Group 1 were in the age group of 21–30 years (40%) and in Group 2, in the age group of 11–20 years (38%) with a mean age 28.4 ± 1.3 years. The most common symptoms in Group 1 patients were sneezing (90%) and rhinorrhea (68%) and in Group 2 wheezing (86%), followed by shortness of breath (66%). The most common sign in Group 1 was B/L inferior turbinate hypertrophy (70%), while in Group 2, it was rhonchi (76%). Mean absolute eosinophil count was 575.35 in Group 1 and was 446.61 in Group 2. Nasal smear for eosinophil was positive for 86% of patients in Group 1 and bronchial lavage showed eosinophilia in 64% of Group 2 patients. Mean total serum immunoglobulin E was 777.23 IU/ml in Group 1 and 662.08 IU/ml in Group 2. The incidence of bronchial asthma in patients of allergic rhinitis was 36%, while the incidence of allergic rhinitis in patients in bronchial asthma was 74%. CONCLUSION: Thus, in our study, we found that both the diseases were closely linked clinicopathologically epidemiologically as well as immunologically pointing toward the concept one-airway one disease.

Introduction: Pseudomonas aeruginosa (P. aeruginosa) is a usual causative organism of both hospital-acquired pneumonia and community-acquired pneumonia. Although, it is less commonly reported in otherwise healthy hosts, most patients have an identifiable risk factor for disease. These risk factors include those with structural lung abnormalities like bronchiectasis and those with a compromised immune system. With the emergence of multidrug resistant strains of P. aeruginosa, the severity of infection and mortality associated with pneumonia has increased drastically. The insight into the risk factors of Pseudomonas pneumomia helps to suspect and treat the condition at the earliest and thereby reduce the mortality as well as the duration of hospital stay. Aim: To determine various risk factors associated with P. aeruginosa pneumonia. Materials and Methods: An observational cross-sectional study was conducted from November 2018 to November 2020 at Jawaharlal Nehru Medical College, Aligarh, Uttar Pradesh, Inida, after obtaining Institutional Ethics Committee (IEC) approval. A total of 89 patients with diagnosis of Pseudomonas pneumonia, defined as the presence of signs and symptoms of pneumonia along with sputum or tracheal culture positive for P. aeruginosa were enrolled in the study. These patients were thoroughly assessed by clinical history, physical examination and relevant investigations to detect any risk factors like age, diabetes, smoking, Chronic Obstructive Pulmonary Disease (COPD), chronic steroid use and prior hospital admission. Data analysis was done using Statistical Package for Social Sciences (SPSS version 22.0). Categorical variables were compared with the Chi-square test. Results: Out of 89 patients with Pseudomonas pneumonia, 77.5% were above 40 years of age, 37.08% were smokers, 25.84% had COPD, 22.47% had bronchiectasis, 31.46% were diabetic, 15.73% were on long term steroid use and 14.61% had history of prior hospital admission. Conclusion: Age, smoking, structural lung diseases like COPD, bronchiectasis, long term steroid use and prior hospital admission are important risk factors for Pseudomonas pneumonia.

DevOps (development and operations) is a collective and multidisciplinary organizational effort used by many software development organizations to build high-quality software on schedule and within budget. Implementing DevOps is challenging to implement in software organizations. The DevOps literature is far away from providing a guideline for effectively implementing DevOps in software organizations. This study is conducted with the aim to develop a readiness model by investigating the DevOps-related factors that could positively or negatively impact DevOps activities in the software industry. The identified factors are further categorized based on the internal and external aspects of the organization, using the SWOT (strengths, weaknesses, opportunities, threats) framework. This research work is conducted in three different phases: (1) investigating the factors, (2) categorizing the factors using the SWOT framework, and finally, (3) developing an analytic hierarchy process (AHP)-based readiness model of DevOps factors for use in software organizations. The findings would provide a readiness model based on the SWOT framework. The proposed framework could provide a roadmap for organizations in the software development industry to evaluate and improve their implementation approaches to implement a DevOps process.

Background: Tuberculosis (TB) remains a major global health problem. India accounts for the one-fourth of the global TB burden. For resource-limited countries like India having high burden of TB, smear microscopy is the most commonly used method for microbiological diagnosis. Although culture being highly sensitive and specific method, it is time-consuming. Under Revised National TB Control Program (RNTCP), Ziehl–Neelsen (ZN) stain-based microscopy and light-emitting diode-based fluorescent microscopy (LED-FM) are being recommended. Aim: The present study was done to determine the sensitivity and specificity of ZN stain-based microscopy and FM (LED-FM) keeping solid culture as gold standard. Materials and Methods: A total of 1503 sputum samples were collected from suspected cases of pulmonary TB (new or previously treated). They were processed and subjected to ZN (conventional light microscopy), Auramine-O (AO) staining (LED-FM) and solid culture on Lowenstein–Jensen medium for detection of acid-fast bacilli. Positive smears were graded according to RNTCP guidelines. Results: Sensitivity, specificity, positive predictive value, and negative predictive value of ZN staining technique were 84.93%, 95.74%, 96.50%, and 82.16%, respectively, and that of FM was 95.25%, 91.33%, 93.81%, and 93.31%, respectively. Conclusion: LED-FM being more sensitive, especially in detecting the paucibacillary cases and less time-consuming, has advantage over ZN method. Nation-wide implementation will lead to improved diagnosis, thus better control of TB.

Pirfenidone has been approved for the treatment of idiopathic pulmonary fibrosis due to its anti-fibrotic activity. It has been shown to have anti-inflammatory and antioxidant properties apart from being an anti-fibrotic agent. Cytokine storm, severe inflammation and oxidative stress leading to acute respiratory distress syndrome and multiorgan failure are factors causing mortality in patients of COVID-19. This article reports two cases of 35 years and 60-year-old male patients of COVID-19, those were diagnosed by real time Polymerase Chain Reaction (PCR) using nasopharyngeal samples. They were started on pirfenidone 400 mg BD, later increased to 600 mg TDS along with empirical antibiotics, dexamethasone, supplemental oxygen and non-invasive ventilator support. Both the patients improved and were discharged. Both the patients were followed by telemedicine after one week, did not require oxygen at rest and were comfortable at rest in contrast to earlier complaints. Thus, the authors conclude that pirfenidone can be a possible cure for COVID-19 patients, larger trials are required to confirm its efficacy.

Introduction: Pleural effusions are one of the most common entities encountered by pulmonologists worldwide which have a very long list of causes. Initial workup of these patients begins with a chest X-ray and percutaneous or Ultrasound (USG) guided thoracocentesis followed by biochemical and cytological evaluation of the fluid to ascertain the cause of effusion. A 20 to 25% of cases remain undiagnosed even after thoracocentesis and closed pleural biopsy. Medical Thoracoscopy is emerging as a safe diagnostic procedure in these patients. Aim: To detect the diagnostic yield of medical thoracoscopy in cases of undiagnosed exudative lymphocytic pleural effusion and to study the complications associated with it. Materials and Methods: This was a prospective observational study, carried out in the Department of Pulmonary Medicine, JN Medical College and hospital, Aligarh Muslim University (AMU), Aligarh, Uttar Pradesh, India, from August 2016 to August 2018. Undiagnosed exudative pleural effusion was defined as pleural effusion with Adenosine Deaminase (ADA) levels less than 70 IU/L and negative pleural fluid cytology for malignancy. Thoracoscopic examination of the pleural space using flexi-rigid thoracoscopy was done and biopsy was taken from suspected areas and the tissue obtained, was send for histopathological examination. The results were presented as mean±SD (Standard Deviation) or percentage. Differences in categorical data were compared using the chi-square test or the Fisher-exact test. A p-value of

ABSTRACT Introduction: An upper respiratory tract infection which can be either due to increased airway bacterial load or emergence of new bacterial strain is the most common cause of Acute Exacerbation of Chronic Obstructive Pulmonary Disease (AECOPD). Other factors responsible for exacerbation include viral infections, pollution and other unidentified pathogens. Aim: To evaluate the local pattern of bacterial and fungal isolates from patients diagnosed with AECOPD and forming an antibiogram of the hospital. Materials and Methods: A total of 200 clinically diagnosed cases of AECOPD of age ≥40 years were included in the study. Sputum sample was obtained from the patients and processed according to standard lab procedures. Statistical analysis was done by using Statistical Package for Social Sciences (SPSS) version-20. The test applied in the current study was modified chi-square used for comparison of proportion to analyse statistical significance for antibiotic sensitivity. The p-value

Pulmonary involvement is common in patients with systemic sclerosis. The most common underlying histology is Non Specific Interstitial Pneumonia (NSIP). Disrupted immunity from the disease or associated medication may render such patients prone to develop tuberculosis infection. A 55-year-old female patient presented with chief complaints of shortness of breath from past five years which was gradually progressive, cough initially dry later with minimal expectoration, low grade fever from past two months. She also gave history of bluish discolouration of fingers tips on exposure to cold water. On examination there was restrictive mouth opening, thickened skin over hands, forearm, face, neck and trunk on pinching. Sclerodactyly was present with clubbing grade 2. On auscultation bilateral fine crepts were present. Serum ANA was highly raised and Scl 70 was positive. PFT was suggestive of restrictive ventilatory abnormality. Sputum smear for AFB was found to be positive. HRCT thorax was suggestive of NSIP. Patient was put on antituberculer treatment under DOTS category 1; nifedipine, pentoxyphylline and nitroglycerine gel was started for raynauds phenomenon. Chemotherapy for systemic sclerosis was given with cyclophosphamide infusion in six cycles every four weeks.

Background: The prevalence of multidrug-resistant-tuberculosis (MDR-TB) among new and previously treated cases is increasing worldwide as well as in India. Rapid detection of MDR-TB allows the establishment of an effective treatment regimen; minimizes the risk of further resistance, and limits the spread of drug-resistant strains. Early diagnosis of MDR-TB is the need of the hour in high-TB burden countries like India, and GenotypeMTBDRplus is quite sensitive and specific in determining the molecular resistance in drugs such as rifampicin and isoniazid. Methods: The present study was done for molecular detection of rifampicin and isoniazid resistance and resistance patterns among MDR-TB suspects and comparison of resistance patterns among new and previously treated cases by GenoType® MTBDRplus Line Probe Assay. A total of 1268 sputum samples of MDR-TB suspects were subjected to fluorescent microscopy. Fluorescent microscopy positive samples were subjected to GenoType® MTBDRplus (HAIN Lifescience) assay. Results: MDR-TB was detected 11.02%, 20.03% in new and previously treated cases. Among MDR-TB patients S531 L was the most common mutation detected in rpoB gene; 71.43% in new, and 72.17% in previously treated cases. S315T1 was the most common mutation noted in katG gene; 100% in new and 81.74% in previously treated. While in hA gene, it was C15T (7.8%) among previously treated cases. Conclusion: MDR-TB has high prevalence in the western part of Uttar Pradesh, India. Previously treated cases have even more high rate of MDR-TB than new TB cases. The most dominant gene mutations associated with resistance to INH and RIF were observed in codon 315 of the katG gene and codon 531 of the rpoB gene. While comparing the mutation patterns by Genotype MTBDRplus assay, previously treated cases showed more diversity of mutations and had greater number of unknown mutations.

Introduction: Amplification of airway inflammation and its destruction due to oxidative stress is a major step in the pathogenesis of chronic obstruction pulmonary disease (COPD). Exhaled carbon monoxide (eCO) may be quantified to evaluate the airway inflammation and oxidative stress in such patients. Objectives: To assess the disease severity of COPD and treatment response by measuring eCO as a biomarker. Materials and Methods: COPD patients diagnosed according to the global initiative for chronic obstructive lung disease guidelines and healthy individuals as controls were selected. One hundred and fifty patients with COPD and 125 controls were included in the study. Participants were further subdivided on the basis of their smoking habits. Clinical examinations and spirometry were done to diagnose COPD by following the standard protocol. eCO was measured using a piCO + Smokerlyzer (Breath CO Monitor, Bedfont Scientific Ltd., Kent, UK). It was a single-center cross-sectional study. Results: Mean (± standard error of mean) CO levels in ex-smokers with COPD were higher (5.21 ± 1.546 ppm; P < 0.05) than in nonsmoking controls (1.52 ± 0.571 ppm) but were lower than in current smokers with COPD (12.55 ± 4.514 ppm; P < 0.05). eCO levels were higher in current smokers with COPD (12.55 ± 4.514 ppm; P < 0.05) compared to healthy smokers (9.71 ± 5.649). There was a negative correlation between eCO and forced expiratory volume in 1 s (FEV1) in COPD (r = −0.28; P < 0.05). The mean eCO level was decreased (6.291–4.332; P < 0.001) with improvement in lung function (FEV1 38.75%–50.65%: P < 0.05) after treatment with inhaled steroid. Conclusion: Our study concludes that quantification of eCO level in COPD varies with different grades of airway obstruction and to measure the treatment response. Measuring the level of eCO can be used to assess the indirect assessment of airway inflammation, oxidative stress, and severity of airway obstruction in COPD patients.

We investigate the impact of the Demonetization of 85% currency in circulation in India on the eve of 8 November 2016 on all the listed stocks spanning over 20 broad industry clusters (sectors) and their affiliation type from the Indian economy over the period of November to Mid-January 2016. Using the event study methodology, we assess the effects of Demonetization, relative to what had been anticipated, as measured by abnormal returns (ARs). The results indicate that Group Affiliated firms witnessed the highest negative abnormal returns both on the event days and during the event window period, while PSUs witnessed the least wrath. On the sectoral front, Demonetization shows a mixed effect in the early days which changes to positive for most of the sectors barring a few. Banking Sector was the worst hit in the early days with a CAAR of −1.74%, while many sectors like Pharma, Paper and Wholesale Trading witnessed a windfall gain in the long run.

Phrenic nerve palsy causing hemidiaphragm paralysis is a very uncommon feature of thoracic aortic aneurysm. In one case, a 30 year male complained of chronic dull aching chest pain, and hoarseness of voice; posteroanterior view chest radiograph revealed large spherical radiopacity on the left upper lung zone with smooth lobulated margin with elevated left hemidiaphragm. On Colour Doppler sonography, lesion was anechoic on gray scale sonography but on Doppler analysis revealed intense internal vascularity within it with characteristic "Ying Yang" sign. The finding favor the vascular origin of the lesion and a diagnosis of an arterial aneurysm was made Contrast-enhanced computed tomography (CT) of the thorax revealed a large well defined spherical lesion of 8 × 10 cm size with smooth well defined margin arising from the aortic arch and attenuation of impending rupture or dissection were lesion on immediate post contrast and delayed scan was similar to that of aorta. Left hemidiaphragm elevation was explained by the gross mass effect of the aneurysm causing right phrenic nerve palsy.

Introduction: The role of vitamin D in bone homeostasis is well known but nowadays, its role in various essential body processes including prevention of various infective and chronic illnesses like Tuberculosis (TB), by facilitating adaptive and innate immunity in lungs and peripheral blood, is being a matter of debate. Low levels have been associated with respiratory tract infections like TB. Present study aimed to evaluate the level of vitamin D in tubercular patients. Aim: To determine serum vitamin D level in patients with TB and compare it with controls. To compare serum vitamin D level among different types of TB, including Pulmonary TB (PTB), tubercular lymphadenitis and tubercular pleural effusion. Materials and Methods: The present study was a single centre cross-sectional study done during the study period from September 2013 to September 2016 at a tertiary care centre of Uttar Pradesh, India. Total 216 subjects aged between 21 and 60 years were included randomly out of which 113 patients were cases and 103 were controls. Cases of TB were confirmed by sputum Acid Fast Bacilli (AFB) staining, sputum and pleural fluid cytology, Adenosine Deaminase (ADA) of pleural fluid and Fine Needle Aspiration Cytology (FNAC) of lymph nodes. Controls were healthy subjects. Total serum vitamin D levels were measured by Diasorin competitive Radioimmunoassay (RIA) (Autoimmune Diagnostika, GmbH, Strasburg, Germany). Results: The mean serum vitamin D level for patients with TB was 22.4±8.5 ng/mL. Among controls, it was 30.5±8.6 ng/mL (p

Introduction: Nosocomial infections have been considered as a major health problem causing incremental morbidity, mortality and costs of therapy. Aim: This retrospective study was initiated with aim to analyse the comparative efficacy of a novel Antibiotic Adjuvant Entity (AAE), a combination of ceftriaxone + sulbactam + disodium edetate and meropenem in combination with colistin, for the management of Multi Drug Resistant (MDR) nosocomial Gramnegative bacterial infections. Materials and Methods: Case history sheets of patients with documented MDR nosocomial Gram-negative infections who received either AAE or meropenem in combination with colistin for management of infections over a period of 3 years (November 2012 – October 2015) were included in the study. Data related to clinical management, demographics, vital signs and laboratory parameters along with prior antibiotic therapy, dose and clinical outcomes were evaluated thoroughly to analyse the clinical benefits of this new AAE+ colistin therapy for management of MDR nosocomial infections. Results: Out of 115 patients short listed for the study, 52 patients had received AAE + colistin therapy and 63 patients have received meropenem + colistin. AAE + colistin therapy resulted in significantly higher efficacy (86.53%) as compared to meropenem + colistin (63.49%). A rising trend in clinical cure rates was observed in AAE based combination therapy in contrast to the decreasing trend in meropenem based combination therapy. A progressive decline in clinical cure rates was observed in meropenem treated group over a period of 3 years due to rising carbapenemases and multiple resistance by pathogens, where as AAE maintained the same efficacy. Conclusion: The AAE + colistin therapy has shown better bacteriological and clinical efficacy as compared to meropenem + colistin in the management of various nosocomial MDR Gramnegative infections. A significant number of meropenem failure patients responded to the AAE therapy highlighting the new hope to spare carbapenems.

Context: Asthma is a chronic airway disorder which is associated to the inflammatory cells. Inflammatory and immune cells generate more reactive oxygen species in patients suffering from asthma which leads to tissue injury. Aims: To investigate the role of oxidant-antioxidant imbalance in disease progression of asthmatic patients. Settings and Design: In this study, 130 asthmatic patients and 70 healthy controls were documented. Methods: For this malondialdehyde level, total protein carbonyls, sulfhydryls, activity of superoxide dismutase (SOD), catalase, glutathione peroxidase (GPx), total blood glutathione, and total antioxidant capacity (FRAP) were measured. Statistical Analysis Used: Analysis of the data was done using unpaired student t test and one-way ANOVA analysis. P < 0.05 was considered significant. Results: The present work showed that the systemic levels of MDA (4.19 ± 0.10 nmol/ml, P < 0.001) and protein carbonyls (1.13 ± 0.02 nmol/mg, P < 0.001) were found to be remarkably higher in asthmatic patients while protein sulfhydryls (0.55 ± 0.01 mmol/l, P < 0.05) decreased as compared to controls (2.84 ± 0.12 nmol/ml, 0.79 ± 0.02 nmol/mg and 0.60 ± 0.02 mmol/l, respectively). We also observed decrease in activities of SOD (2047 ± 50.34 U/g Hb, P < 0.05), catalase (4374 ± 67.98 U/g Hb, P < 0.01), and GPx (40.97 ± 1.05 U/g Hb, P < 0.01) in erythrocytes compared to control (2217 ± 60.11 U/g Hb, 4746 ± 89.94 U/g Hb, and 48.37 ± 2.47 U/g Hb, respectively). FRAP level (750.90 ± 21.22 ΅mol/l, P < 0.05) in plasma was decreased, whereas total blood glutathione increased (0.94 ± 0.02 mmol/l, P < 0.05) as seen in control (840.40 ± 28.39 ΅mol/l and 0.84 ± 0.04 mmol/l). Conclusions: This work supports and describes the hypothesis that an imbalance between oxidant-antioxidant is associated to the oxidative stress which plays a significant role in severity of the disease.

Patients with laryngeal cancer have a high risk of developing lung cancer in the future. A patient presented with a complaint of left-sided chest pain for the last 3 months. Chest X-ray posterior-anterior view showed a homogeneous opacity in the left upper lung field with elevation of the diaphragm on the left side. CECT thorax revealed a heterogeneously enhancing soft tissue density mass lesion in the superior segment of the lingular lobe. On histopathological examination of the mass lesion, it was diagnosed as adenocarcinoma of the lung. About 10 months previously, the patient was treated for a laryngeal squamous cell carcinoma. Patients with laryngeal cancer should be routinely screened during follow-up with chest X-ray or CT scan for the early detection of lung cancer.

C-reactive protein (CRP) is an acute-phase protein synthesized predominantly by the hepatocytes in response to tissue damage or inflammation. Levels of acute-phase proteins rise rapidly, during infection and after injury. We take up the study to correlate serum CRP levels with other important predictive markers of outcome in COPD. Patient with stable COPD (no exacerbation in the last two months) were taken up for the study. Parameters taken to correlate were age, grade of dyspnea, FEV1. It was found the CRP is negatively correlated with FEV1 and grade of dyspnea but not correlated with age.

BACKGROUND AND PURPOSE: The effects of nicotine on cerebral metabolism and its influence on smoking behavior is poorly understood. An understanding of the chronic effects of nicotine on excitatory and inhibitory metabolic demand, and corresponding neurotransmission may provide clues for designing strategies for the optimal smoking cessation intervention. The objective of the current study was to investigate neuronal and astroglial metabolism in mice exposed to nicotine (0.5 and 2.0 mg/kg, s.c.) three times in a day for 4 weeks. EXPERIMENTAL APPROACH/PRINCIPAL FINDINGS: Metabolic measurements were carried out by co-infusing [U-(13)C(6)]glucose and [2-(13)C]acetate, and monitoring (13)C labeling of amino acids in brain tissue extract using (1)H-[(13)C] and (13)C-[(1)H]-NMR spectroscopy. Concentration of (13)C-labeled glutamate-C4 was increased significantly from glucose and acetate with chronic nicotine treatment indicating an increase in glucose oxidation by glutamatergic neurons in all brain regions and glutamate-glutamine neurotransmitter cycle in cortical and subcortical regions. However, chronic nicotine treatment led to increased labeling of GABA-C2 from glucose only in the cortical region. Further, increased labeling of glutamine-C4 from [2-(13)C]acetate is suggestive of increased astroglial activity in subcortical and cerebellum regions of brain with chronic nicotine treatment. CONCLUSIONS AND SIGNIFICANCE: Chronic nicotine exposure enhanced excitatory activity in the majority of brain regions while inhibitory and astroglial functions were enhanced only in selected brain regions.

This paper examines the relationship between ex-ante stock liquidity and abnormal returns during various phases of COVID-19 led market uncertainties in India. We find that the volume-based liquidity supports stock more significantly during the crisis than in periods of calm. However, contrary to existing empirical evidence, price-based liquidity penalizes stocks during a crisis. Moreover, during periods of calm and recovery, the inverse relationship of liquidity-abnormal return reverses. Further analysis shows that this change of price-based liquidity to abnormal return relationship is more prominent in firms with higher ex-ante liquidity. In contrast, highly illiquid firms appear immune. [ABSTRACT FROM AUTHOR]

This study investigates the critical firm-level strengths and weaknesses that explain cross-sectional variations in abnormal stock returns of Hospitality and Tourism (HT) firms during different phases of a crisis. We used the event study and multivariate regression framework for analysing the Indian HT firms' data around the COVID-19 crisis. While reporting a significant negative influence of COVID-19, we identified the early crisis, market crash and continuation of the crisis periods. Furthermore, we observe that during the early-crisis period, business diversity, financial stability and board diversity improved HT firms' strength to withstand the risk, while business group affiliation was of little help. During the market crash and continuation of the crisis phase, better capital intensity and financial stability proved helpful. The managers of HT firms can take cues from this study to understand firm-level characteristics that provide resilience to their firms' value in managing different phases of the crisis.

The present study investigates the changes in G20 stock market dynamics and their interlinkages in the aftermath of COVID-19. It utilizes the Detrended Cross-Correlation Analysis (DCCA) along with the network and complexity theories for detecting the contagion effect of the pandemic on the stock markets. We find that both advanced and emerging stock markets, departing from their pre-crisis structures, form a tightly coupled close community after the disease outbreak – except for China that distanced itself from the rest of the cohort. This indicates that COVID-19 has caused contagion in the global equity market, which has increased the risk to international portfolio diversification benefits. The adoption of the Network theory for contagion detection technique augments the detailed understanding of the structural changes and their interlinkages among the stock markets in a more comprehensive way.

The Indian securities market regulator intervened in June 2010 with a regulatory amendment in the listing requirement that mandated all the listed firms other than PSUs (government‐owned companies) to have a minimum public shareholding of 25%. The affected firms were given a 3‐year window to comply with the regulation. This study examines the impact of the new regulation on the affected firms' value. We explore the relationship between improvement in firms' value and stock liquidity. This regulatory intervention offers a natural experiment to examine direct causality between stock liquidity and firms' value. The findings of the empirical analysis confirm the existence of a direct causal relationship between stock liquidity and firm value, stemming from an improved operating performance.

We investigate whether increased Algorithmic Trading (AT) intensity caused by the introduction of Co-location trading (CLT) facilities improve the productive efficiency of the Indian stock indices. We measure the change in the speed of information adjustment and change of persistence before and after the introduction of CLT for Indian Indices. We report an improvement in the overall productive efficiency of the leading Indian Indices, Midcap and Smallcap indices being the prominent beneficiaries. Our work contributes to the empirical literature on the ongoing debate on the benefits of AT and its role in improving market efficiency, especially in the emerging markets context.

The present study views adventure tourism through a services marketing lens to investigate the impact of customer experience on tourist satisfaction. It further explores the mediating role of commitment between tourists’ satisfaction and behavioural intents, that is, their revisit intentions (RVIs). The adventure activities under consideration in this study are trekking and rafting. A survey of participants with experience in trekking and rafting was conducted to establish support for the proposed model. The findings of the study indicate that quality of experience positively affects satisfaction, which in turn leads to positive commitment and enhances RVIs of the tourists. [ABSTRACT FROM AUTHOR]

Background: We report the clinical efficacy against COVID-19 infection of BBV152, a whole virion inactivated SARS-CoV-2 vaccine formulated with a toll-like receptor 7/8 agonist molecule adsorbed to alum (Algel-IMDG) in Indian adults.Methods: We did a randomised, double-blind, placebo-controlled, multicentre, phase 3 clinical trial in 25 Indian hospitals or medical clinics to evaluate the efficacy, safety, and immunological lot consistency of BBV152. Adults (age ≥18 years) who were healthy or had stable chronic medical conditions (not an immunocompromising condition or requiring treatment with immunosuppressive therapy) were randomised 1:1 with a computer-generated randomisation scheme (stratified for the presence or absence of chronic conditions) to receive two intramuscular doses of vaccine or placebo administered 4 weeks apart. Participants, investigators, study coordinators, study-related personnel, the sponsor, and nurses who administered the vaccines were masked to treatment group allocation; an unmasked contract research organisation and a masked expert adjudication panel assessed outcomes. The primary outcome was the efficacy of the BBV152 vaccine in preventing a first occurrence of laboratory-confirmed (RT-PCR-positive) symptomatic COVID-19 (any severity), occurring at least 14 days after the second dose in the per-protocol population. We also assessed safety and reactogenicity throughout the duration of the study in all participants who had received at least one dose of vaccine or placebo. This report contains interim results (data cutoff May 17, 2021) regarding immunogenicity and safety outcomes (captured on days 0 to 56) and efficacy results with a median of 99 days for the study population. The trial was registered on the Indian Clinical Trials Registry India, CTRI/2020/11/028976, and ClinicalTrials.gov, NCT04641481 (active, not recruiting).Findings: Between Nov 16, 2020, and Jan 7, 2021, we recruited 25 798 participants who were randomly assigned to receive BBV152 or placebo; 24 419 received two doses of BBV152 (n=12 221) or placebo (n=12 198). Efficacy analysis was dependent on having 130 cases of symptomatic COVID-19, which occurred when 16 973 initially seronegative participants had at least 14 days follow-up after the second dose. 24 (0·3%) cases occurred among 8471 vaccine recipients and 106 (1·2%) among 8502 placebo recipients, giving an overall estimated vaccine efficacy of 77·8% (95% CI 65·2-86·4). In the safety population (n=25 753), 5959 adverse events occurred in 3194 participants. BBV152 was well tolerated; the same proportion of participants reported adverse events in the vaccine group (1597 [12·4%] of 12 879) and placebo group (1597 [12·4%] of 12 874), with no clinically significant differences in the distributions of solicited, unsolicited, or serious adverse events between the groups, and no cases of anaphylaxis or vaccine-related deaths.Interpretation: BBV152 was highly efficacious against laboratory-confirmed symptomatic COVID-19 disease in adults. Vaccination was well tolerated with no safety concerns raised in this interim analysis.Funding: Bharat Biotech International and Indian Council of Medical Research. [ABSTRACT FROM AUTHOR]
