SummaryBackgroundIndia has 18% of the global population and an increasing burden of chronic respiratory diseases. However, a systematic understanding of the distribution of chronic respiratory diseases and their trends over time is not readily available for all of the states of India. Our aim was to report the trends in the burden of chronic respiratory diseases and the heterogeneity in their distribution in all states of India between 1990 and 2016.MethodsUsing all accessible data from multiple sources, we estimated the prevalence of major chronic respiratory diseases and the deaths and disability-adjusted life-years (DALYs) caused by them for every state of India from 1990 to 2016 as part of the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2016. We assessed heterogeneity in the burden of chronic obstructive pulmonary disease (COPD) and asthma across the states of India. The states were categorised into four groups based on their epidemiological transition level (ETL). ETL was defined as the ratio of DALYs from communicable diseases to those from non-communicable diseases and injuries combined, with a low ratio denoting high ETL and vice versa. We also assessed the contribution of risk factors to DALYs due to COPD. We compared the burden of chronic respiratory diseases in India against the global average in GBD 2016. We calculated 95% uncertainty intervals (UIs) for the point estimates.FindingsThe contribution of chronic respiratory diseases to the total DALYs in India increased from 4·5% (95% UI 4·0–4·9) in 1990 to 6·4% (5·8–7·0) in 2016. Of the total global DALYs due to chronic respiratory diseases in 2016, 32·0% occurred in India. COPD and asthma were responsible for 75·6% and 20·0% of the chronic respiratory disease DALYs, respectively, in India in 2016. The number of cases of COPD in India increased from 28·1 million (27·0–29·2) in 1990 to 55·3 million (53·1–57·6) in 2016, an increase in prevalence from 3·3% (3·1–3·4) to 4·2% (4·0–4·4). The age-standardised COPD prevalence and DALY rates in 2016 were highest in the less developed low ETL state group. There were 37·9 million (35·7–40·2) cases of asthma in India in 2016, with similar prevalence in the four ETL state groups, but the highest DALY rate was in the low ETL state group. The highest DALY rates for both COPD and asthma in 2016 were in the low ETL states of Rajasthan and Uttar Pradesh. The DALYs per case of COPD and asthma were 1·7 and 2·4 times higher in India than the global average in 2016, respectively; most states had higher rates compared with other locations worldwide at similar levels of Socio-demographic Index. Of the DALYs due to COPD in India in 2016, 53·7% (43·1–65·0) were attributable to air pollution, 25·4% (19·5–31·7) to tobacco use, and 16·5% (14·1–19·2) to occupational risks, making these the leading risk factors for COPD.InterpretationIndia has a disproportionately high burden of chronic respiratory diseases. The increasing contribution of these diseases to the overall disease burden across India and the high rat...

BackgroundIn ST-elevation myocardial infarction (STEMI), prehospital delay is a significant factor, decreasing likelihood of revascularization and increasing mortality. Prehospital delays are substantive in Indian patients with STEMI. Our study aimed to investigate factors associated with prehospital delay in patients with STEMI.MethodsA multicentric prospective analysis was conducted at five major cardiac care referral centers in Punjab including a tertiary care teaching hospital over a period of 1 year from January 2015 to December 2015. Patients presenting with STEMI were included in the study. A structured questionnaire was used to gather patient characteristics and factors responsible for prehospital delay.ResultsOf the 619 patients included in the study, 42% presented with more than 6 h of prehospital delay. On univariate analysis, delay was significantly higher among elderly (p = 0.01), illiterate patients (p = 0.02), and patients residing in rural areas (p = 0.04). Recognizing symptoms as cardiac in origin (p < 0.001), hospital as initial medical contact, and availability of prehospital electrocardiogram (ECG) (p = 0.001) were associated with shorter delays. On multivariate analysis, prehospital delay was significant in elderly patients, initial point of care as outpatient clinic, and patients without access to prehospital ECG.ConclusionOur study concludes that demographic and socioeconomic barriers exist that impede rapid care seeking and highlights the need for utilization of prehospital ECG to decrease prehospital delay. Possibilities include, educating the public on the importance of early emergency medical services contact or creating emergency stations in rural areas with ECG capabilities. Our study also invites further research, regarding role of telemedicine to triage patients derived from prehospital ECGs to decrease prehospital delay.

Veno-arterial ECMO has been shown to improve the short-term survival of patients with AlP poisoning having severe LV myocardial dysfunction. A low baseline LVEF and longer delay in hospital presentation were found to be predictors of mortality even after ECMO usage. Large, adequately controlled and standardized trials with long-term follow-up must be performed to confirm these findings.
