Disparities in Nutrition Counseling at Pediatric Wellness Visits in South Carolina.

In 2007, an Expert Committee recommended that dietary patterns be assessed at each wellness visit and that counseling on diet and nutrition be provided to all children. Few studies have examined the "uptake" of obesity prevention practices into pediatric primary care. This study aimed to describe patterns of nutrition counseling among children at wellness visits in South Carolina between 2008 and 2017 and determine whether sociodemographic disparities existed.

Army Warrior Care Project (AWCP): Rationale and methods for a longitudinal study of behavioral health care in Army Warrior Transition Units using Military Health System data, FY2008-2015.

Objectives: Warrior Transition Units (WTUs) are specialized military units co-located with major military treatment facilities providing a Triad of Care involving primary care physicians, case managers, and military leadership to soldiers needing comprehensive medical care. We describe the rationale and methods for studying behavioral health care in WTUs and characterize soldiers assigned to WTUs.

Methods: The Army Warrior Care Project (AWCP) analyzes U.

Behavioral Health Service Use by Military Children During Afghanistan and Iraq Wars.

Medical claims were analyzed from 2810 military children who visited a civilian emergency department (ED) or hospital from 2000 to 2014 with behavioral health as the primary diagnosis and TRICARE as the primary/secondary payer. Visit prevalence was estimated annually and categorized: 2000-2002 (pre-deployment), 2003-2008 (first post-deployment), 2009-2014 (second post-deployment). Age was categorized: preschoolers (0-4 years), school-aged (5-11 years), adolescents (12-17 years).

Purchased Behavioral Health Care Received by Military Health System Beneficiaries in Civilian Medical Facilities, 2000-2014.

Introduction: Behavioral health conditions are a significant concern for the U.S. military and the Military Health System (MHS) because of decreased military readiness and increased health care utilization.

Statewide Longitudinal Progression of the Whole-Patient Measure of Safety in South Carolina.

Meaningful improvement in patient safety encompasses a vast number of quality metrics, but a single measure to represent the overall level of safety is challenging to produce. Recently, Perla et al. established the Whole-Person Measure of Safety (WPMoS) to reflect the concept of global risk assessment at the patient level.

Differences in Hospital Readmission Risk across All Payer Groups in South Carolina.

Objective: To evaluate differences in hospital readmission risk across all payers in South Carolina (SC).

Data Sources/study Setting: South Carolina Revenue and Fiscal Affairs Office (SCRFA) statewide all payer claims database including 2,476,431 hospitalizations in SC acute care hospitals between 2008 and 2014.

Study Design: We compared the odds of unplanned all-cause 30-day readmission for private insurance, Medicare, Medicaid, uninsured, and other payers and examined interaction effects between payer and index admission characteristics using generalized estimating equations.

Inactivation of bacterial spores and viruses in biological material using supercritical carbon dioxide with sterilant.

The purpose of this study was to validate supercritical carbon dioxide (SC-CO(2)) as a terminal sterilization method for biological materials, specifically acellular dermal matrix. In this study, bacterial spores, Bacillus atrophaeus, were inoculated onto porcine acellular dermal matrix to serve as a "worst case" challenge device. The inactivation of the spores by SC-CO(2) with peracetic acid (PAA) sterilant was analyzed as a function of exposure times ranging from 1 to 30 min.

Microneedle-based intradermal delivery of the anthrax recombinant protective antigen vaccine.

The recombinant protective antigen (rPA) of Bacillus anthracis is a promising anthrax vaccine. We compared serum immunoglobulin G levels and toxin-neutralizing antibody titers in rabbits following delivery of various doses of vaccine by microneedle-based intradermal (i.d.

Protective immunization against inhalational anthrax: a comparison of minimally invasive delivery platforms.

A new anthrax vaccine under clinical investigation is based on recombinant Bacillus anthracis protective antigen (rPA). Here, we investigated microneedle-based cutaneous and nasal mucosal delivery of rPA in mice and rabbits. In mice, intradermal (id) delivery achieved up to 90% seroconversion after a single dose, compared with 20% after intramuscular (im) injection.

Role of tumor necrosis factor receptor 1 (p55) in hepatocyte proliferation during acetaminophen-induced toxicity in mice.

Hepatocyte proliferation represents an important part of tissue repair. In these studies, TNF receptor 1 (TNFR1) knockout mice were used to analyze the role of TNF-alpha in hepatocyte proliferation during acetaminophen-induced hepatotoxicity. Treatment of wild-type (WT) mice with acetaminophen (300 mg/kg) resulted in centrilobular hepatic necrosis.

Osteopontin facilitates bone resorption, decreasing bone mineral crystallinity and content during calcium deficiency.

Osteopontin null-mice were previously shown to have bones containing more mineral and larger mineral crystals. These bones were independently seen to be resistant to ovariectomy-induced remodeling. To separate the physicochemical effects of osteopontin, which is an in vitro inhibitor of mineral crystal formation and growth, from effects of osteopontin on in vivo bone remodeling, this study examined mature (5-month-old) osteopontin-null (Opn-/-) and wildtype (WT) mice given a calcium-deficient diet.

Role of p55 tumor necrosis factor receptor 1 in acetaminophen-induced antioxidant defense.

Tumor necrosis factor (TNF)-alpha is a macrophage-derived proinflammatory cytokine implicated in hepatotoxicity. In the present studies, p55 TNF receptor 1 (TNFR1) -/- mice were used to assess the role of TNF-alpha in acetaminophen-induced antioxidant defense. Treatment of wild-type (WT) mice with acetaminophen (300 mg/kg) resulted in centrilobular hepatic necrosis and increased serum alanine transaminases.

Differential induction of heme oxygenase-1 in macrophages and hepatocytes during acetaminophen-induced hepatotoxicity in the rat: effects of hemin and biliverdin.

Heme oxygenase-1 (HO-1), also known as heat shock protein 32, has been shown to protect against oxidant-induced tissue injury. In the present studies, we analyzed expression of this enzyme in macrophages and hepatocytes following acetaminophen administration and its potential role in hepatotoxicity. Treatment of rats with a hepatotoxic dose of acetaminophen (1 g/kg, ip) resulted in a time-dependent induction of HO-1 in the liver.

Improved genetic immunization via micromechanical disruption of skin-barrier function and targeted epidermal delivery.

Skin is an attractive target for delivery of genetic therapies and vaccines. However, new approaches are needed to access this tissue more effectively. Here, we describe a new delivery technology based on arrays of structurally precise, micron-scale silicon projections, which we term microenhancer arrays (MEAs).

Tissue injury following inhalation of fine particulate matter and hydrogen peroxide is associated with altered production of inflammatory mediators and antioxidants by alveolar macrophages.

Hydrogen peroxide (H(2)O(2)) is present in the atmosphere at concentrations known to induce cell and tissue damage. However, inhaled H(2)O(2) vapor should not reach the lower lung due to its high water solubility. It has been suggested that hygroscopic components of particulate matter (PM) may transport H(2)O(2) into the lower lung and induce tissue injury and this was investigated.

Identification of distinct molecular phenotypes in cultured gastrointestinal smooth muscle cells.

Background & Aims: Cultured gastrointestinal smooth muscle cells have been shown to dedifferentiate and reinitiate their myogenic program in vitro. The aim of this study was to determine whether the cellular phenotypes observed in vitro were similar to those previously characterized in vivo.

Methods: Differential isoactin expression was examined in primary cultures of intestinal smooth muscle cells (ISMCs) by Northern blot and immunohistochemical analysis.

Comparative analysis of smooth muscle isoactin gene expression in normal and neoplastic tissues.

Monoclonal antibodies derived from the actin multigene family are routinely used as an adjunct to morphologic diagnoses of smooth muscle tumors. Northern blot analysis was performed on 60 surgical resections utilizing isoactin-specific cDNAs. A comparison of this analysis to immunohistochemical studies demonstrated that actin-specific monoclonal antibodies represent reliable markers of the smooth muscle lineage.

In vitro study of placental trophoblast calcium uptake using JEG-3 human choriocarcinoma cells.

During human fetal development, placental syncytiotrophoblasts actively transport calcium from the maternal to the fetal circulation. Two functional components, a cytosolic Ca2(+)-binding protein (CaBP) and a Ca2(+)-ATPase have been identified in the syncytiotrophoblasts of the chorionic villi. We report here the calcium uptake properties of a human choriocarcinoma cell line, JEG-3, which was used as an in vitro model cell system for the syncytiotrophoblasts.

Identification of serotonergic neurons in human brain by a monoclonal antibody binding to all three aromatic amino acid hydroxylases.

A monoclonal antibody, PH8, has been isolated and shown by immunocytochemistry to bind to serotonergic and catecholaminergic neurons in sections of the rat and human brain. In human brain, obtained at autopsy, particular fixation and embedding conditions eliminate the labelling of catecholaminergic neurons while leaving intact the labelling of serotonergic neurons. This property makes the antibody of potential use for structural studies of serotonergic neurons in the normal and diseased human brain.

Perivascular pseudorosettes in childhood brain tumours: an ultrastructural and immunohistochemical study.

Perivascular pseudorosettes (PP) in childhood central nervous system tumours were examined with light and electron microscopy and immunohistochemistry for glial fibrillary acidic protein, S-100 protein and albumin. One kind of PP at light microscopy comprised a central thin-walled vessel surrounded by a thick mantle of eosinophilic fibrillary material and rings of usually regular nuclei. Adjacent tumour tissue was compact.
