Clinical Phenotypes and Disease-specific Health-related Quality of Life in Patients of Chronic Obstructive Pulmonary Disease.

Background: Chronic Obstructive Pulmonary Disease (COPD) is a common health issue globally and is expected to increase in the future. The latest Global Initiative for COPD (GOLD) guidelines describe the various phenotypes of COPD. This study assessed the different clinical phenotypes and disease-specific health-related quality of life (HRQoL) in patients with COPD.

Prospective evaluation of ethambutol toxic optic neuropathy in patients of pulmonary tuberculosis.

Aim: The aim of the study was to evaluate visual parameters for early detection of ethambutol toxicity to prevent irreversible optic nerve damage.

Method: This cohort study included 50 newly diagnosed cases of pulmonary tuberculosis, i.e.

Air pollution and its effects on lung health in never-smoker youth of Delhi NCR versus Pauri Garhwal: a comparative cross-sectional study.

Background: Ambient air pollution is a major factor that can affect lung growth and reduce lung capacity. This study aims at drawing parallel between respiratory discomfort and lung function between youth of Delhi-National Capital Region (NCR) where air pollution level is poor and hazardous as compared to that of Pauri Garhwal (Uttarakhand) where air pollution level is low via a comparative cross-sectional study.

Methods: A community-based cross-sectional study conducted among 354 never-smoker subjects (177 from NCR and 177 from Pauri) between the ages of 15 and 29 years.

Isolated pulmonary hemorrhage after electric shock: a rare phenomenon.

Any type of contact with electricity of low or high voltage can cause injury to the human body, with a variable effect on the body. Low-voltage injury is quite common worldwide, but there is very little information present in the available literature. The degree of organ damage depends on many factors, which include the duration of electric current exposure, current type, and nature of the affected tissue.

Pulmonary function in cured pulmonary tuberculosis cases.

Background: In clinical practice it has been observed that several patients of cured pulmonary tuberculosis (PTB) suffer with lung dysfunction and these problems are less documented routinely. Prevalence of these abnormalities remains unknown. Aim of this study is to estimate the lung function abnormality and exercise capacity including diffusion capacity of lung for carbon monoxide (DLCO) in cured PTB cases.

Gut bacterial profile in Indian children of varying nutritional status: a comparative pilot study.

Purpose: Childhood malnutrition is a multifactorial disease, responsible for nearly half of all deaths in children under five. Lately, the probable association of a dysbiotic gut to malnutrition is also being eagerly investigated. The current study is an attempt to investigate this purported association through assessing the abundance of major gut bacterial phyla (Firmicutes, Bacteroidetes, Actinobacteria and Proteobacteria), probionts (Bifidobacteria and Lactobacillus), butyrogens (Faecalibacterium and Roseburia) and pathogens (Escherichia and Klebsiella).

Assessment of psychiatric co-morbidities in patient of bronchial asthma attending a tertiary medical centre (Multicentric study).

Aims And Objectives: Asthma is a chronic inflammatory condition, which is associated with increase in airway hyper responsiveness that leads to recurrent episodes of wheezing, breathlessness, chest tightness and coughing. Asthma is a very common respiratory illness, in which some of the disease related factors may increases the vulnerability to psychiatric disorders. This study was done to determine the prevalence of psychiatric co-morbidity in patients of bronchial asthma.

Enhanced electron transfer mediated detection of hydrogen peroxide using a silver nanoparticle-reduced graphene oxide-polyaniline fabricated electrochemical sensor.

The current study aims at the development of an electrochemical sensor based on a silver nanoparticle-reduced graphene oxide-polyaniline (AgNPs-rGO-PANI) nanocomposite for the sensitive and selective detection of hydrogen peroxide (HO). The nanocomposite was fabricated by simple synthesis of PANI at the surface of rGO sheet which was followed by stirring with AEC biosynthesized AgNPs to form a nanocomposite. The AgNPs, GO, rGO, PANI, rGO-PANI, and AgNPs-rGO-PANI nanocomposite and their interaction were studied by UV-vis, FTIR, XRD, SEM, EDX and XPS analysis.
