E-selectin, a cytoadhesive glycoprotein, is expressed on venular endothelial cells and mediates leukocyte localization to inflamed endothelium, the first step in inflammatory cell extravasation into tissue. Constitutive marrow endothelial E-selectin expression also supports bone marrow hematopoiesis via NF-κB-mediated signaling. Correspondingly, E-selectin interaction with E-selectin ligand (sialyl Lewis) on acute myeloid leukemia (AML) cells leads to chemotherapy resistance in vivo.

However, low ability to navigate the healthcare system and lack of health insurance may mean that those who are experiencing homelessness may not receive the healthcare that they need.
Objectives: This study uses risk factors at baseline to predict hospitalization at follow-up.

California used the Medicaid expansion provisions of the Affordable Care Act (ACA) to enroll low-income men between the ages of 18 and 64 years in publicly funded health insurance. Most studies on the effect of the ACA on health care services have focused on racial/ethnic differences rather than gender.

The current study reports about the relationships between survival sex trading (SST) and high-risk behaviors in a sample of adults. Bivariate analysis shows that HIV-positive status, use of cocaine, ketamine, methamphetamine, heroin, having received drug treatment, and having received medical services are associated with SST.

Data were collected from 525 clients who visited the Center for Behavioral Research and Services in Long Beach, CA, using the following instruments: Risk Behavior Assessment, Risk Behavior Follow-Up Assessment, the Aggression Questionnaire (AQ), the Displaced AQ, and the parole and Legal Status section of the Addiction Severity Index. The bivariate analysis suggested that ED use was significantly associated with trait aggression and trait-displaced aggression among those with a history of incarceration.

Self-report data were collected from 2369 women who received services through HIV and sexually transmitted infection (STI) testing programs and a subset were tested for HIV, hepatitis B, hepatitis C, and syphilis. Results revealed those women who traded sex only for money used condoms, were tested for HIV, and received the HIV test results more often than the other women.

Background: Alcohol and drug use by women is related to high-risk sexual practices and protective behaviors.
Objectives: To determine sexual risk and protective behaviors using information about women's drug use immediately before or during sex.
Methods: Latent class analysis using PROC LCA in SAS software was used to determine classes of women using both past 30-day drug use and before or during sex.
The development of rapid point-of-care tests for HIV infection has greatly reduced the problem of failure to return for test results. Test manufacturers are now developing test kits that can test for two or even three diseases at the same time, multiple-disease test kits. This study reports on the sensitivity and specificity of HIV tests when included on multi-disease test kits.

The pharmacokinetic characteristics of sublingually administered tablets containing 15 or 30 µg of sufentanil are described.
Methods: Blood was sampled from healthy subjects (four studies, 122 subjects) and patients (seven studies, 944 patients).
Background/aims: MOD-4023 is a long-acting human growth hormone (hGH) in clinical trials for the treatment of growth hormone deficiency (GHD). A key goal is maintenance of serum concentrations of insulin-like growth factor (IGF) 1 within normal range throughout GH dosing. The study aimed to develop a pharmacokinetic model for MOD-4023 and a pharmacodynamic model for the effect of MOD-4023 on IGF-1 to allow estimation of peak and mean IGF-1 and to identify the optimal IGF-1 sampling day.

Three hundred ninety-six adults were administered the Wender Utah Rating Scale, the Risk Behavior Assessment, the Aggression Questionnaire (AQ), and the Displaced Aggression Questionnaire (DAQ). Those with ADHD were higher on all scales of the AQ and DAQ, were younger at first use of amphetamines, and were more likely to have ever used crack and amphetamines.

We evaluated the impact of these covariates on the plasma concentration (Cp) profile of sumatriptan administered subcutaneously.
Methods: We conducted three pharmacokinetic studies of subcutaneous sumatriptan in 98 healthy adults.
Objective/background: Intranasal sumatriptan (Imitrex ) may be an alternative for patients who refuse injections and cannot tolerate oral agents, but due to low bioavailability and slow absorption, the clinical utility of the currently marketed formulation is limited, highlighting an unmet need for an effective non-oral migraine medication with a rapid onset of action. To overcome the slow absorption profile associated with intranasal administration, we evaluated the impact of 1-O-n-Dodecyl-β-D-Maltopyranoside (DDM, Intravail A-3™), a permeation enhancer, on sumatriptan's pharmacokinetic profile by comparing the pharmacokinetic characteristics of two commercial sumatriptan products, 4 mg subcutaneous and 6 mg subcutaneous in healthy adults, with DFN-02 - a novel intranasal agent comprised of sumatriptan 10 mg plus 0.20% DDM.

The femininity subscale score on the BSRI, ever having had gonorrhea and age were the three variables identified in a multivariate linear regression significantly predicting use of total health services. This supports the hypothesis that sex roles can assist our understanding of men's use of health services.

This randomized pilot study aimed to determine whether a single session of psychoeducation improved mental health outcomes, attitudes toward treatment, and service engagement among urban, impoverished, culturally diverse, trauma-exposed adults. Sixty-seven individuals were randomly assigned to a single-session psychoeducation treatment or a delayed treatment comparison control group. The control group was found to be superior to the treatment group at posttest with respect to symptoms of posttraumatic stress disorder, anxiety, and occupational and family disability.
