Demographic, Health Care, and Fertility-related Characteristics of Adults Aged 18-44 Who Have Ever Been in Foster Care: United States, 2011-2017.

Objective-This report presents demographic characteristics, health service access and use, and timing of key fertility-related milestones among adults aged 18-44 who had ever been in foster care as compared with those who had never been in foster care in the United States. Methods-The National Survey of Family Growth (NSFG) is a nationally representative survey, with data collected through in-person interviews of the household population of the United States. Analyses used 6 years of NSFG interviews spanning September 2011 through September 2017, and included 11,527 male and 14,439 female respondents aged 18-44. Bivariate analyses examined demographic characteristics and health service access and use by having ever been in foster care, as measured by household roster information and childhood background items. Cumulative probabilities of first sexual intercourse, first marriage, and first birth by age were estimated using Kaplan-Meier procedures. All estimates were stratified by sex. Results-Overall, 2.6% of adults aged 18-44 had ever been in foster care, and the percentage was higher for women (3.0%) than for men (2.3%). Lower percentages of men and women who were ever in foster care had a bachelor's degree or higher (4.8% for men and 9.1% for women) compared with those who had never been in foster care (31.1% and 36.2%, respectively). Receipt of public assistance in the past 12 months was more likely among adults who were ever in foster care compared with those who were never in foster care. Adults ever in foster care were less likely than adults never in foster care to be currently covered by private health insurance and were more likely to be covered by Medicaid. Adults ever in foster care also had higher probabilities of first sexual intercourse and first births at younger ages than those never in foster care.

Adoption-related Behaviors Among Women Aged 18-44 in the United States: 2011-2015.

People may choose to adopt a child for several reasons, including starting or growing a family, infertility, legal acknowledgment of a parental relationship with a nonbiological child, or for humanitarian reasons (1,2). Since 1973, the National Survey of Family Growth (NSFG) has gathered data from women on adoption and adoption-related topics (3-7). Using data from NSFG, this report provides the most recent estimates on current adoption and adoption-related behaviors among women aged 18-44 in the United States in 2011-2015.

Acid and base stress and transcriptomic responses in Bacillus subtilis.

Acid and base environmental stress responses were investigated in Bacillus subtilis. B. subtilis AG174 cultures in buffered potassium-modified Luria broth were switched from pH 8.5 to pH 6.0 and recovered growth rapidly, whereas cultures switched from pH 6.0 to pH 8.5 showed a long lag time. Log-phase cultures at pH 6.0 survived 60 to 100% at pH 4.5, whereas cells grown at pH 7.0 survived <15%. Cells grown at pH 9.0 survived 40 to 100% at pH 10, whereas cells grown at pH 7.0 survived <5%. Thus, growth in a moderate acid or base induced adaptation to a more extreme acid or base, respectively. Expression indices from Affymetrix chip hybridization were obtained for 4,095 protein-encoding open reading frames of B. subtilis grown at external pH 6, pH 7, and pH 9. Growth at pH 6 upregulated acetoin production (alsDS), dehydrogenases (adhA, ald, fdhD, and gabD), and decarboxylases (psd and speA). Acid upregulated malate metabolism (maeN), metal export (czcDO and cadA), oxidative stress (catalase katA; OYE family namA), and the SigX extracytoplasmic stress regulon. Growth at pH 9 upregulated arginine catabolism (roc), which generates organic acids, glutamate synthase (gltAB), polyamine acetylation and transport (blt), the K(+)/H(+) antiporter (yhaTU), and cytochrome oxidoreductases (cyd, ctaACE, and qcrC). The SigH, SigL, and SigW regulons were upregulated at high pH. Overall, greater genetic adaptation was seen at pH 9 than at pH 6, which may explain the lag time required for growth shift to high pH. Low external pH favored dehydrogenases and decarboxylases that may consume acids and generate basic amines, whereas high external pH favored catabolism-generating acids.
