Association of COVID-19 With Emergence of Comorbidities: A Hospital-Based Cohort Study.

Background: In 2019, the emergence of SARS-CoV-2 marked the beginning of the COVID-19 global pandemic, which reached its peak in 2020. Initially designated as a novel coronavirus, SARS-CoV-2 emerged as a respiratory illness and later began causing multi-organ complications in recovered patients.

Methods: This article presents a hospital-based retrospective cohort study conducted via telephone interviews with patients in a tertiary hospital.

Clinical profile of small-cell lung cancer in North India: A 12-year analysis from a tertiary care center.

Introduction: The small cell variant is a relatively uncommon but aggressive form of lung cancer. The present study aims to analyse the clinical characteristics, treatment outcomes and prognostic factors of an ambispectively enrolled large cohort of small cell lung cancer (SCLC) in the Indian population over a decade-long period.

Materials And Methods: All patients diagnosed with SCLC between 2008 and 2020 at a tertiary care lung cancer clinic were included.

Evaluation of delays during diagnosis and management of lung cancer in India: A prospective observational study.

Objective: The majority of lung cancers are diagnosed at an advanced stage; the reasons for which are variable and unclear.

Methods: Lung cancer patients were evaluated prospectively to quantify various timelines and establish reasons for delays. Timelines were defined as time intervals between symptom onset, first physician visit, first specialist visit, date of diagnosis and treatment.

Prognostic factors for treatment response and survival outcomes after first-line management of Stage 4 non-small cell lung cancer: A real-world Indian perspective.

Background: Indian data on treatment outcomes and survival in advanced non-small cell lung cancer (NSCLC) remain scarce.

Materials And Methods: A retrospective review of 537 advanced NSCLC patients treated at a tertiary care facility in North India from January 2008 to March 2018 was done to assess treatment response and survival in terms of objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), and overall survival (OS).

Results: Median age of enrolled patients was 60 years (range: 26-89 years).

To study heterogeneity in SARS-CoV-2 IgG response titre in patients recovered from COVID-19.

The COVID-19 pandemic caused a serious health challenge to the entire mankind. The association between clinical characteristics of disease and formation of neutralizing antibodies have not well studied. A prospective study was conducted for patients recovered from confirmed SARS-CoV-2 infections from 1st August 2020 to 28th February 2021, to study the association between SARS-CoV-2 IgG antibody response titres and clinical characteristics of the disease.

A randomized comparison of sample adequacy and diagnostic yield of various suction pressures in EBUS-TBNA.

Introduction: The evidence for using vacuum suction during EBUS is sparse and the optimal suction pressure for obtaining adequate samples has not yet been determined. Our aim was to assess the influence of suction on the adequacy and diagnostic yield of EBUS-TBNA.

Material And Methods: This single-center, prospective, randomized, non-inferiority trial assessed whether no-suction and 10 mL suction are inferior to 20 mL suction for adequacy and diagnostic yield of EBUS-TBNA aspirates.

A comprehensive comparison between young and older-age non-small cell lung cancer patients at a public referral centre in Delhi, India.

Purpose: Given the increasing number of non-small cell lung cancer (NSCLC) patients in India, a comparative analysis between patients under 40 years and those of older age at a major public referral centre would provide insight into the phenotypic patterns of this group.

Methods: NSCLC patients who were accessioned within the lung cancer clinic database of the Pulmonary Medicine Department at the all India institute of medical sciences - Delhi between 2008 and 2019 were reviewed. Patients 40 years or younger and 60 years or older were selected and categorised as young and older patients, respectively.

Not just skin deep: Multiple cutaneous nodules as first presenting sign of small cell cancer.

A 65 years old male, chronic smoker (30 pack years), presented with complaints of dyspnea (mMRC grade2), cough (dry in nature), loss of appetite, loss of weight ( > 5 kgs), weakness, bony pains, feverish feeling and easy fatigability for last 2-3 months.Contrast enhanced CT chest showed bilateral extensive paraseptal and centriacinar emphysematous changes, right upper lobe spiculated heterogeneously enhancing soft tissue lesion and significant conglomerate mediastinal lymphadenopathy encasing lower trachea and great vessels.As patient was high risk for development of pneumothorax related to image guided sampling of right upper lobe lesion in view of extensive emphysema; patient was referred to us for EBUS-TBNA (endobronchial ultrasound guided transbronchial needle aspiration) guided mediastinal lymph nodes sampling.

Knowledge, anxiety and the use of hydroxychloroquine prophylaxis among health care students and professionals regarding COVID-19 pandemic.

Introduction: Data regarding knowledge and attitude about COVID-19, the prevalence of acceptance of hydroxychloroquine prophylaxis and anxiety amidst COVID-19 pandemic among health care students/professionals in India is scarce.

Material And Methods: A cross-sectional study was conducted during May 2020, using an online survey via Google forms. A self-administered validated structured questionnaire was applied, which comprised 28 questions among health care students/professionals at a tertiary care centrein North India.

Mediastinal germ cell tumour masquerading as loculated pleural effusion.

Benign mediastinal teratomas often discovered while patients are still asymptomatic. Almost all arise in the anterosuperior mediastinal compartment. Most symptoms result from compression of adjacent structures.

Clinical predictors of response to EGFR-tyrosine kinase inhibitors in EGFR-mutated non-small cell lung cancer: A real-world multicentric cohort analysis from India.

Background: The development of various targeted therapies against Epidermal Growth Factor Receptor (EGFR) has been a major step in therapeutic advancements in lung cancer. However, the response to tyrosine kinase inhibitors (TKI) therapy in a real-world setting has not been well elucidated.

Methods: As part of a retrospective analysis, patients with EGFR mutated non-small cell lung cancer at 4 tertiary care Institutions in North India between December 2007 and August 2018 were evaluated.

Guidelines for diagnostic flexible bronchoscopy in adults: Joint Indian Chest Society/National College of chest physicians (I)/Indian association for bronchology recommendations.

Flexible bronchoscopy (FB) is commonly performed by respiratory physicians for diagnostic as well as therapeutic purposes. However, bronchoscopy practices vary widely across India and worldwide. The three major respiratory organizations of the country supported a national-level expert group that formulated a comprehensive guideline document for FB based on a detailed appraisal of available evidence.

Clinical profile of lung cancer in North India: A 10-year analysis of 1862 patients from a tertiary care center.

Introduction: Over the past few years, the demographic profile of lung cancer has changed. However, most reports are limited by small numbers, short follow-up period, and show an inconsistent pattern. A comprehensive evaluation of changing trends over a long period has not been done.
