A study found sharp increases in heart failure and pneumonia following the Japanese earthquake, while stroke and cardio-pulmonary arrest rates followed seismic peaks. Blood pressure was also elevated, but medication disruptions may have contributed to cardiovascular events.
A new study found that pneumonia and preterm birth complications are leading causes of childhood death, accounting for 64% of deaths globally. Despite a decline in total deaths between 2000 and 2010, the reduction is not sufficient to meet the Millennium Development Goal of reducing child mortality by two-thirds by 2015.
Recent studies suggest a decline in pneumonia hospitalizations and inpatient deaths in the US. However, analysis of data from the Nationwide Inpatient Sample reveals that trends in diagnostic coding, such as increased use of sepsis and respiratory failure codes, may be driving these declines.
