This report presents final 2006 data on U.S. deaths, death rates, life expectancy, infant and maternal mortality, and trends by selected characteristics such as age, sex, Hispanic origin, race, marital status, educational attainment, injury at work, state of residence, and cause of death. It also presents more detailed information than previously presented about the mortality experience of the American Indian or Alaska Native and the Asian or Pacific Islander populations. ⋯ Mortality patterns in 2006, such as the decline in the age-adjusted death rate to a record historical low, were generally consistent with long-term trends. Life expectancy increased in 2006 from 2005.

Measure compliance with the Accreditation Council of Graduate Medical Education (ACGME) residents' work hour regulations and evaluate their impact on patient care and residents' performance on the Otolaryngology Training Examination (OTE). ⋯ Institution of the ACGME duty hour regulations did not improve patient care as measured by the 30-day readmission rate, inhospital mortality, and patient's length of stay. Residents' performance on the OTE did not change after implementation of the ACGME rules. Further studies are warranted to assess the impact of the ACGME work hour regulations on patient care and resident-physicians' training.

An evaluation of serial blood lactate measurement as an early predictor of shock and its outcome in patients of trauma or sepsis.
Attainment of hemodynamic parameters to within a normal range may leave patients in compensatory shock. In such patients, serial blood lactate evaluation can be useful in predicting shock. ⋯ Serial lactate values followed over a period of time can be used to predict impending complications or grave outcome in patients of trauma or sepsis. Interventions that decrease lactate values to normal early may improve chances of survival and can be considered effective therapy. Lactate values need to be followed for a longer period of time in critical patients.

Air pollution and survival within the Washington University-EPRI veterans cohort: risks based on modeled estimates of ambient levels of hazardous and criteria air pollutants.
For this paper, we considered relationships between mortality, vehicular traffic density, and ambient levels of 12 hazardous air pollutants, elemental carbon (EC), oxides of nitrogen (NOx), sulfur dioxide (SO2), and sulfate (SO4(2-)). These pollutant species were selected as markers for specific types of emission sources, including vehicular traffic, coal combustion, smelters, and metal-working industries. Pollutant exposures were estimated using emissions inventories and atmospheric dispersion models. ⋯ However, we have not evaluated possible contributions from road dust or traffic noise. Stratification by traffic density level suggests the presence of response thresholds, especially for gaseous pollutants. Because of their wider distributions of estimated exposures, risk estimates based on emissions and atmospheric dispersion models tend to be more precise than those based on local ambient measurements.

The main associations of body-mass index (BMI) with overall and cause-specific mortality can best be assessed by long-term prospective follow-up of large numbers of people. The Prospective Studies Collaboration aimed to investigate these associations by sharing data from many studies. ⋯ Although other anthropometric measures (eg, waist circumference, waist-to-hip ratio) could well add extra information to BMI, and BMI to them, BMI is in itself a strong predictor of overall mortality both above and below the apparent optimum of about 22.5-25 kg/m(2). The progressive excess mortality above this range is due mainly to vascular disease and is probably largely causal. At 30-35 kg/m(2), median survival is reduced by 2-4 years; at 40-45 kg/m(2), it is reduced by 8-10 years (which is comparable with the effects of smoking). The definite excess mortality below 22.5 kg/m(2) is due mainly to smoking-related diseases, and is not fully explained.
