BACKGROUND: Endovascular procedures come with a potential risk of radiation hazards both to patients and to the vascular staff. Classically, most endovascular interventions took place in regular operating rooms using a fluoroscopy C-arm unit controlled by a third party. Hybrid operating rooms (HOR) provide an optimal surgical suit with all the qualities of a fixed C-arm device, while allowing the device to be controlled by the surgical team. The latest studies suggest that an operator-controlled system may reduce the radiation dose...

Recent calls for a revision of standard evolutionary theory (SET) are based partly on arguments about the reciprocal causation. Reciprocal causation means that cause-effect relationships are bi-directional, as a cause could later become an effect and vice versa. Such dynamic cause-effect relationships raise questions about the distinction between proximate and ultimate causes, as originally formulated by Ernst Mayr. They have also motivated some biologists and philosophers to argue for an Extended Evolutionary Synthesis (EES)...

Oral fluid (OF) is a highly effective substrate for population-based HIV screening efforts, as it is noninfectious and significantly easier to collect than blood. However, anti-HIV antibodies are found at far lower concentrations in OF compared with blood, leading to poor sensitivity and a longer period of time from infection to detection threshold. Thus, despite its inherent advantages in sample collection, OF is not widely used for population screening. Here we report the development of an HIV OF assay based on Antibody Detection by Agglutination-PCR (ADAP) technology...

BACKGROUND: The implementation of Medicare part D on January 1, 2006 required all adults who were dually enrolled in Medicaid and Medicare (dual eligibles) to transition prescription drug coverage from Medicaid to Medicare part D. Changes in payment systems and utilization management along with the loss of Medicaid protections had the potential to disrupt medication access, with uncertain consequences for dual eligibles with human immunodeficiency virus (HIV) who rely on consistent prescription coverage to suppress their HIV viral load (VL)...

The renal podocyte is central to the filtration function of the kidney that is dependent on maintaining both highly organized, branched cell structures forming foot processes, and a unique cell-cell junction, the slit diaphragm. Our recent studies investigating the developmental formation of the slit diaphragm identified a novel claudin family tetraspannin, TM4SF10, which is a binding partner for ADAP (also known as Fyn binding protein Fyb). To investigate the role of ADAP in podocyte function in relation to Fyn and TM4SF10, we examined ADAP knockout (KO) mice and podocytes...

Although the immune adaptor adhesion and degranulation-promoting adaptor protein (ADAP) acts as a key mediator of integrin inside-out signaling leading to T cell adhesion, the regulation of this adaptor during integrin activation and clustering remains unclear. We now identify Ubc9, the sole small ubiquitin-related modifier E2 conjugase, as an essential regulator of ADAP where it is required for TCR-induced membrane recruitment of the small GTPase Rap1 and its effector protein RapL and for activation of the small GTPase Rac1 in T cell adhesion...

ADAP-GC is an automated computational workflow for extracting metabolite information from raw, untargeted gas chromatography-mass spectrometry metabolomics data. Deconvolution of coeluting analytes is a critical step in the workflow, and the underlying algorithm is able to extract fragmentation mass spectra of coeluting analytes with high accuracy. However, its latest version ADAP-GC 3.0 was not user-friendly. To make ADAP-GC easier to use, we have developed ADAP-GC 3.2 and describe here the improvements on three aspects...

OBJECTIVES: To determine the effectiveness of a universal school-based depression education program. METHODS: In 2012-2015, we matched 6679 students from 66 secondary schools into pairs by state (Maryland, Delaware, Pennsylvania, Michigan, and Oklahoma) and randomized to the Adolescent Depression Awareness Program (ADAP; n = 3681) or to a waitlist control condition (n = 2998). Trained teachers delivered ADAP as part of the health education curriculum to students aged 14 to 15 years...

Antiretroviral (ARV) adherence has largely been considered from the perspective of an individual's behavior with less attention given to potential structural causes for lapses in treatment, such as the cost of medications and care. HIV medication expense is typically covered by third party payers. However, private insurance premiums and deductibles may rise, or policies terminated such as with a change in employment. Likewise, a patient's eligibility for publicly funded coverage like state AIDS Drug Assistance Programs (ADAP) or Medicaid can also be lost...

Purpose/aim of the study: Cognitive functioning in the Morris Water Maze (MWM) is assumed to be reflected by path length. In this study, the interference of motor deficits, as a confounding factor on cognitive functioning, was assessed by means of a lateralization study with hemicerebellectomized (HCX) mice. This model is characterized by motor deficits restricted to the lesion side, allowing comparison within the model itself (left vs. right), rather than the effect of the manipulation on this measure (experimental vs...

BACKGROUND: The relative contribution of psychological factors to the onset and course of inflammatory bowel diseases (IBD) is a matter of constant debate since its beginning, as is the clinical need and the efficacy of psychotherapeutic interventions. However, the perspective of patients with IBD has largely been ignored in this debate. METHODS: Psychometric tests including the Short-Form IBD Questionnaire (SIBDQ), the ADAP test measuring demand for psychotherapy, and the Fear-of-Progression Questionnaire Short Form as well as disease-related questions were positioned on the internet between December 2014 and January 2016...

BACKGROUND: Among low-income women with and without HIV, it is a priority to reduce age-related comorbidities, including hypertension and its sequelae. Because consistent health insurance access has been identified as an important factor in controlling many chronic diseases, we estimated the effects of coverage interruption on loss of hypertension control in a cohort of women in the United States. METHODS: We analyzed prospective, longitudinal data from the Women's Interagency HIV Study...

Background: Knowledge gaps remain about how the Ryan White human immunodeficiency virus (HIV)/AIDS Program (RW) contributes to health outcomes. We examined the association between different RW service classes and retention in care (RiC) or viral suppression (VS). Methods: We identified Virginians engaged in any HIV care between 1 January and 31 December 2014. RW beneficiaries were classified by receipt of ≥1 service from 3 classes: Core medical, Support, and insurance and/or direct medication assistance through the AIDS Drug Assistance Program (ADAP)...

BACKGROUND: Implementation of the Affordable Care Act motivates assessment of health insurance and supplementary programs, such as the AIDS Drug Assistance Program (ADAP) on health outcomes of HIV-infected people in the United States. We assessed the effects of health insurance, ADAP, and income on HIV viral load suppression. METHODS: We used existing cohort data from the HIV-infected participants of the Women's Interagency HIV Study. Cox proportional hazards models were used to estimate the time from 2006 to unsuppressed HIV viral load (>200 copies/mL) among those with Medicaid, private, Medicare, or other public insurance, and no insurance, stratified by the use of ADAP...

Integrin-mediated cell adhesion and signaling is of critical importance for neuronal differentiation. Recent evidence suggests that an "inside-out" activation of β1-integrin, similar to that observed in hematopoietic cells, contributes to the growth and branching of dendrites. In this study, we investigated the role of the hematopoietic adaptor protein adhesion and degranulation promoting adapter protein (ADAP) in these processes. We demonstrate the expression of ADAP in the developing and adult nervous hippocampus, and in outgrowing dendrites of primary hippocampal neurons...

The clinical potential of transplantation is often reduced by T cell-mediated alloresponses that cause graft rejection or graft-versus-host disease. Integrin-mediated adhesion between alloreactive T cells and antigen-presenting cells is essential for allorejection. The identity of the signaling events needed for the activation of integrins such as LFA-1 is poorly understood. Here, we identified a novel role of the protein tyrosine phosphatase SHP-1 in the regulation of murine LFA-1-mediated adhesion in an allograft setting...

Therapy-related myeloid neoplasms are neoplastic processes arising as a result of chemotherapy, radiation therapy, or a combination of these modalities given for a primary condition. The disease biology varies based on the etiology and treatment modalities patients receive for their primary condition. Topoisomerase II inhibitor therapy results in balanced translocations. Alkylating agents, characteristically, give rise to more complex karyotypes and mutations in p53. Other etiologies include radiation therapy, high-dose chemotherapy with autologous stem cell transplantation and telomere dysfunction...
