Growth Performance, Metabolomics, and Microbiome Responses of Weaned Pigs Fed Diets Containing Growth-Promoting Antibiotics and Various Feed Additives.

The objective of this study was to determine the potential biological mechanisms of improved growth performance associated with potential changes in the metabolic profiles and intestinal microbiome composition of weaned pigs fed various feed additives. Three separate 42 day experiments were conducted to evaluate the following dietary treatments: chlortetracycline and sulfamethazine (PC), herbal blends, turmeric, garlic, bitter orange extract, sweet orange extract, volatile and semi-volatile milk-derived substances, yeast nucleotide, and cell wall products, compared with feeding a non-supplemented diet (NC). In all three experiments, only pigs fed PC had improved ( < 0.

Experimental facility had a greater effect on growth performance, gut microbiome, and metabolome in weaned pigs than feeding diets containing subtherapeutic levels of antibiotics: A case study.

The objective of this study was to define changes in the intestinal metabolome and microbiome associated with growth performance of weaned pigs fed subtherapeutic concentrations of antibiotics. Three experiments with the same antibiotic treatments were conducted on the same research farm but in two different facilities (nursery and wean-finish) using pigs weaned at 20-days of age from the same source herd and genotype, and fed the same diets formulated without antibiotics (NC) or with 0.01% chlortetracycline and 0.

Assessing the frequency with which primary care providers address sleep of infants and young children.

Sleep problems during early development are common and associated with negative health outcomes. Earlier recognition of poor sleep health permits earlier intervention and improved outcomes. This retrospective cohort study aimed to identify the frequency with which primary care providers assessed sleep health when completing the Rourke Baby Record for infants and young children during routine well-baby visits from 2002 to 2019.

Abortion Access for Incarcerated People: Incidence of Abortion and Policies at U.S. Prisons and Jails.

Objective: To understand abortion incidence among incarcerated people and the relation to prison and jail pregnancy policies.

Methods: We collected abortion numbers and policy data from convenience sample of 22 state prison systems, all Federal Bureau of Prisons sites, and six county jails that voluntarily reported monthly, aggregate pregnancy outcomes for 12 months in 2016-2017. Sites also completed a baseline survey of institution characteristics and pregnancy policies, including abortion.

Objectives: To collect national data on pregnancy frequencies and outcomes among women in US state and federal prisons.

Methods: From 2016 to 2017, we prospectively collected 12 months of pregnancy statistics from a geographically diverse sample of 22 state prison systems and the Federal Bureau of Prisons. Prisons reported numbers of pregnant women, births, miscarriages, abortions, and other outcomes.

Galactomannan Degrading Enzymes from the Mannan Utilization Gene Cluster of Alkaliphilic Bacillus sp. N16-5 and Their Synergy on Galactomannan Degradation.

Two glycoside hydrolases encoded by the mannan utilization gene cluster of alkaliphilic Bacillus sp. N16-5 were studied. The recombinant Gal27A (rGal27A) hydrolyzed both galactomannans and oligo-galactomannans to release galactose, while the recombinant Man113A (rMan113A) showed poor activity toward galactomannans, but it hydrolyzed manno-oligosaccharides to release mannose and mannobiose.

Contraceptive use by disability status: new national estimates from the National Survey of Family Growth.

Objective: The objective was to determine population-based estimates of use of contraception among women 15-44 years of age in the United States by disability status.

Study Design: We examined the relationship between disability status and use of contraception among 7505 women at risk of unintended pregnancy using data from the 2011-2015 National Survey of Family Growth.

Results: After examining the full distribution of contraceptive method use by disability status, we found that disability status was significantly associated with differences in three categories of use: female sterilization, the oral contraceptive pill and nonuse of contraception.

Obesity and contraceptive use among women 20-44years of age in the United States: results from the 2011-15 National Survey of Family Growth (NSFG).

Objective: Obesity has increased dramatically in the United States in recent decades. Our objective was to explore associations of contraceptive choices of US women, aged 20-44years, with body mass index (BMI) and relevant covariates.

Study Design: Data are based on interviews with a national sample of 11,300 women in the 2011-2015 National Survey of Family Growth.

Disparities in receipt of family planning services by disability status: New estimates from the National Survey of Family Growth.

Background: A substantial and increasing population of US women of childbearing age live with disability. Disability-based disparities in access to family planning services have been previously documented, but few studies have used population-based data sources or evidence-based measures of disability.

Objective: To determine population-based estimates of use of family planning services among women 15-44 years of age in the United States, and to examine differences by disability status.

Methods We analyzed data from a sample of 5601 US women 15-44 years of age in the 2011-2013 National Survey of Family Growth. The data were analyzed via cross-tabulation and logistic regression.

Trends and determinants of IUD use in the USA, 2002-2012.

Study Question: What factors and subgroups have propelled the recent increase in intrauterine device (IUD) use in the USA?

Summary Answer: The increase in IUD use, from 1.8 to 9.5% in the USA between 2002 and 2012, was driven primarily by a marked uptake among parous women who intended to have more children.

Adipose Natural Killer Cells Regulate Adipose Tissue Macrophages to Promote Insulin Resistance in Obesity.

Obesity-induced inflammation mediated by immune cells in adipose tissue appears to participate in the pathogenesis of insulin resistance. We show that natural killer (NK) cells in adipose tissue play an important role. High-fat diet (HFD) increases NK cell numbers and the production of proinflammatory cytokines, notably TNFα, in epididymal, but not subcutaneous, fat depots.

This report describes current contraceptive use among women of childbearing age (ages 15-44) during 2011-2013. Current contraceptive use is defined as use during the month of interview, not for a specific act of sexual intercourse. This report's primary focus is describing patterns of contraceptive use among women who are currently using contraception, by social and demographic characteristics.

Nonuse of contraception among women at risk of unintended pregnancy in the United States.

Objective: This paper seeks to determine factors associated with nonuse of contraception by women at risk of unintended pregnancy in the United States. This nonuse may be associated with about 900,000 unintended births in the US each year.

Study Design: The 2002 and 2006-2010 National Surveys of Family Growth were combined to yield a nationally representative sample of 9,445 women at risk of unintended pregnancy.

Effect of selenium yeast supplementation on naturally acquired parasitic infection in ewes.

Gastrointestinal parasites cause substantial economic losses in pasture-based sheep production systems. Supranutritional organic selenium (Se) supplementation may be beneficial because it improves immune responses to pathogens. To evaluate the effect of Se-yeast supplementation on gastrointestinal parasite load, 30 ewes per treatment group were drenched weekly with no Se, 4.

Effect of supranutritional organic selenium supplementation on postpartum blood micronutrients, antioxidants, metabolites, and inflammation biomarkers in selenium-replete dairy cows.

Dairy cows have increased nutritional requirements for antioxidants postpartum. Supranutritional organic Se supplementation may be beneficial because selenoproteins are involved in regulating oxidative stress and inflammation. Our objective was to determine whether feeding Se-yeast above requirements to Se-replete dairy cows during late gestation affects blood micronutrients, antioxidants, metabolites, and inflammation biomarkers postpartum.

Effect of transport on blood selenium and glutathione status in feeder lambs.

Stress from transport may be linked to increased generation of reactive oxygen species, the removal of which requires reduced glutathione and selenium. The aim of this experiment was to examine the effect of transport on glutathione and Se status of feeder lambs. Recently weaned lambs (n = 40) were blocked by gender and BW on d 0 of the experiment and randomly assigned to 2 treatment groups: group 1, no transport and full access to feed and water (control), and group 2, 8-h road transport followed by another 16 h of feed deprivation (transport).

Methods: Data for this report come primarily from the 2006-2010 National Survey of Family Growth (NSFG), which included 12,279 interviews with women aged 15-44.

Effect of supranutritional maternal and colostral selenium supplementation on passive absorption of immunoglobulin G in selenium-replete dairy calves.

Selenium (Se) is an essential micronutrient for ruminant animals affecting both performance and immune functions. Adding 3 mg of Se/L (in the form of Na selenite) to colostrum has been shown to improve IgG absorption in Se-deficient newborn dairy calves. The objective of our study was to determine the effect of supranutritional maternal and colostral Se supplementation on IgG status of Se-replete dairy calves.

Selenium supplementation restores innate and humoral immune responses in footrot-affected sheep.

Dietary selenium (Se) alters whole-blood Se concentrations in sheep, dependent upon Se source and dosage administered, but little is known about effects on immune function. We used footrot (FR) as a disease model to test the effects of supranutritional Se supplementation on immune function. To determine the effect of Se-source (organic Se-yeast, inorganic Na-selenite or Na-selenate) and Se-dosage (1, 3, 5 times FDA-permitted level) on FR severity, 120 ewes with and 120 ewes without FR were drenched weekly for 62 weeks with different Se sources and dosages (30 ewes/treatment group).

Effects of feeding selenium-enriched alfalfa hay on immunity and health of weaned beef calves.

Previously, we reported that feeding selenium (Se)-enriched forage improves antibody titers in mature beef cows, and whole-blood Se concentrations and growth rates in weaned beef calves. Our current objective was to test whether beef calves fed Se-enriched alfalfa hay during the transition period between weaning and movement to a feedlot also have improved immune responses and slaughter weights. Recently weaned beef calves (n = 60) were fed an alfalfa-hay-based diet for 7 weeks, which was harvested from fields fertilized with sodium selenate at 0, 22.
