OBJECTIVES We studied the association of certain weather variables (specifically, humidity, wind speed, and barometric pressure) with emergent psychiatric presentations, psychiatric admissions, incidence of violent crimes, and suicides in a metropolitan area.

barometric pressure cycles

Barometric pressure changes can induce airflow in an open borehole or well screened in the vadose zone, thereby ventilating the soil surrounding the borehole. This paper presents an analytic model of the induced airflow and compares the predictions of the model with experimental measurements. This model may be useful for the design of passive soil vapor extraction as applied to the remediation ...

Emergency department visits by adults for psychiatric medication adverse events.

IMPORTANCE In 2011, an estimated 26.8 million US adults used prescription medications for mental illness. OBJECTIVE To estimate the numbers and rates of adverse drug event (ADE) emergency department (ED) visits involving psychiatric medications among US adults between January 1, 2009, and December 31, 2011.

Epidemiology of adult psychiatric visits to US emergency departments.

OBJECTIVES To characterize psychiatric-related emergency department visits (PREDVs) among adults in the United States for the year 2000 and to analyze PREDV trends from 1992 to 2000. METHODS Emergency department (ED) visit data from the National Hospital Ambulatory Medical Care Survey were used to estimate the number of PREDVs for adults aged 18 years and older. A PREDV was defined as any vis...
