Genome dilution by cell growth drives starvation-like proteome remodeling in mammalian and yeast cells.

Cell size is tightly controlled in healthy tissues and single-celled organisms, but it remains unclear how size influences cell physiology. Increasing cell size was recently shown to remodel the proteomes of cultured human cells, demonstrating that large and small cells of the same type can be biochemically different. Here, we corroborate these results in mouse hepatocytes and extend our analysis using yeast.

National Center for Health Statistics Data Presentation Standards for Proportions.

The National Center for Health Statistics (NCHS) disseminates information on a broad range of health topics through diverse publications. These publications must rely on clear and transparent presentation standards that can be broadly and efficiently applied. Standards are particularly important for large, cross-cutting reports where estimates cannot be individually evaluated and indicators of precision cannot be included alongside the estimates.

Racial and Ethnic Differences in a Linkage with the National Death Index.

Objectives: Differences in the availability of a Social Security Number (SSN) by race/ethnicity could affect the ability to link with death certificate data in passive follow-up studies and possibly bias mortality disparities reported with linked data. Using 1989-2009 National Health Interview Survey (NHIS) data linked with the National Death Index (NDI) through 2011, we compared the availability of a SSN by race/ethnicity, estimated the percent of links likely missed due to lack of SSNs, and assessed if these estimated missed links affect race/ethnicity disparities reported in the NHIS-linked mortality data.

Methods: We used preventive fraction methods based on race/ethnicity-specific Cox proportional hazards models of the relationship between availability of SSN and mortality based on observed links, adjusted for survey year, sex, age, respondent-rated health, education, and US nativity.

Characteristics of Physician Office Visits for Obesity by Adults Aged 20 and Over: United States, 2012.

In 2011–2014, current asthma prevalence was higher among adults with obesity compared with adults in lower weight categories. This pattern was consistent across most demographic subgroups, except among men, for whom no statistically significant difference in current asthma prevalence by weight status was observed. Other epidemiologic studies of asthma prevalence have shown conflicting results about whether obesity is a risk factor for asthma among males.
