BACKGROUND Early in life, natural exposure to microbial components (eg, endotoxin) may mitigate allergy and asthma development in childhood. Bacterial DNA is a potent stimulus for the innate immune system; its immune stimulatory potential in dust is unknown. OBJECTIVES We sought to quantify bacterial DNA and endotoxin content in dust from urban homes,(More)
BACKGROUND In the United States, asthma hospitalization rates are disproportionately high among blacks compared with other racial/ethnic groups and vary by geographic region. These disparities among asthma hospitalizations might be affected by social, environmental, and health-care access factors. OBJECTIVE To determine demographic risk factors for asthma(More)
BACKGROUND Large local reactions are not uncommon during allergen immunotherapy (AIT). Dosage adjustments after large local reactions are commonly instituted despite literature that suggests individual large local reactions do not seem to predict subsequent systemic reactions. OBJECTIVE To investigate the relationship between large local reactions and the(More)
Asthma is a chronic inflammatory disease that renders individuals prone to acute exacerbations. Several allergic and nonallergic triggers can incite an asthma exacerbation. The goals of managing an asthma exacerbation are prompt recognition, rapid reversal of airflow obstruction, prevention of relapses, and forestalling future episodes. A written asthma(More)
All patients with asthma are at risk of having asthma exacerbations characterized by worsening symptoms, airflow obstruction, and an increased requirement for rescue bronchodilators. The goals of managing an asthma exacerbation are prompt recognition and rapid reversal of airflow obstruction to avert relapses and future episodes. Short-acting beta-agonists,(More)
Endotoxin is infamous for its ability to exacerbate existing allergy and asthma symptoms. Current research supports this phenomenon, demonstrating its significance in the home, as well as in the workplace. At the same time, evidence is emerging that exposure to endotoxin may drive immune development away from the T-helper lymphocyte type 2-mediated allergy(More)
BACKGROUND & OBJECTIVES Failure to adhere to anti-retroviral therapy (ART) can lead to a range of unfavourable consequences impacting upon people living with HIV (PLH) and society. It is, therefore, paramount that ART adherence is measured in a reliable manner and factors associated with adherence are identified. Lack of such data from West Bengal(More)
Broadband powerline communication is appearing as a competitive solution for last mile connectivity for transmitted multimedia signal. A pilot project initiative was undertaken in the dwelling complexes in the city of Kolkata India for experimenting on broadband powerline communication. Investigations on the performance of high speed communication through(More)
