This paper reports on a process evaluation using mixed methods to assess a Dementia Care Coordination Program, which is distinctive in using the medical system, rather than direct outreach, to identify and refer families to supports provided by an Alzheimer's Association chapter via dedicated care consultants. One care consultant received referrals from individual physicians, while the other, employed by a health plan, received referrals from health plan case managers. Through key informant interviews, focus groups, and physician and caregiver surveys, we identified key issues, finding high rates of stakeholder satisfaction, but some practical issues around information sharing and data tracking...

Bromodomain and extraterminal domain inhibitors (BETi) represent promising therapeutic agents for metastatic melanoma, yet their mechanism of action remains unclear. Here we interrogated the transcriptional effects of BETi and identified AMIGO2, a transmembrane molecule, as a BET target gene essential for melanoma cell survival. AMIGO2 is upregulated in melanoma cells and tissues compared to human melanocytes and nevi, and AMIGO2 silencing in melanoma cells induces G1/S arrest followed by apoptosis. We identified the pseudokinase PTK7 as an AMIGO2 interactor whose function is regulated by AMIGO2...

The evolutionary stability of synthetic genetic circuits is key to both the understanding and application of genetic control elements. One useful but challenging situation is a switch between life and death depending on environment. Here are presented "essentializer" and "cryodeath" circuits, which act as kill switches in Escherichia coli. The essentializer element induces cell death upon the loss of a bi-stable cI/Cro memory switch. Cryodeath makes use of a cold-inducible promoter to express a toxin. We employ rational design and a toxin/antitoxin titering approach to produce and screen a small library of potential constructs, in order to select for constructs that are evolutionarily stable...

This article is grounded in a research programme which set out to understand how to rebuild health systems post-conflict. Four countries were studied-Uganda, Sierra Leone, Zimbabwe and Cambodia-which were at different distances from conflict and crisis, as well as having unique conflict stories. During the research process, the Ebola epidemic broke out in West Africa. Zimbabwe has continued to face a profound economic crisis. Within our research on health worker incentives, we captured insights from 128 life histories and in-depth interviews with a variety of staff that had remained in service...

Despite their proven ability for precise and targeted release, nanoplatform systems for photocontrolled delivery often face formidable synthetic challenges, in part, due to the paucity of advanced linker strategies. Here we report on a novel linker strategy using a thioacetal ortho-nitrobenzaldehyde (TNB) cage, demonstrating its application for delivery of doxorubicin (Dox) in two nanoscale systems. This photocleavable linker, TNB(OH), which presents two identical arms, each terminated with a hydroxyl functionality, was prepared in a single step from 6-nitroverataldehyde...

Policy and financial pressures have driven up use of observation stays for patients in traditional Medicare and the Veterans' Affairs Healthcare System. Using claims data (2004-2014) from OptumLabs™ Data Warehouse, we examined whether people in private Medicare Advantage (MA) and commercial plans experienced similar changes. We found that use of observation increased rapidly for patients in MA plans-even though MA plans were not subject to the same pressures as government-run programs. In contrast, use of observation remained constant for people in commercial plans-except for enrollees 65 and older, for whom it increased somewhat...

Dysregulation of autophagy and inflammasome activity contributes to the development of auto-inflammatory diseases. Emerging evidence highlights the importance of the actin cytoskeleton in modulating inflammatory responses. Here we show that deficiency of Wiskott-Aldrich syndrome protein (WASp), which signals to the actin cytoskeleton, modulates autophagy and inflammasome function. In a model of sterile inflammation utilizing TLR4 ligation followed by ATP or nigericin treatment, inflammasome activation is enhanced in monocytes from WAS patients and in WAS-knockout mouse dendritic cells...

The HIV-1 regulatory protein, trans-activator of transcription (Tat), interacts with opioids to potentiate neuroinflammation and neurodegeneration within the CNS. These effects may involve the C-C chemokine receptor type 5 (CCR5); however, the behavioral contribution of CCR5 on Tat/opioid interactions is not known. Using a transgenic murine model that expresses HIV-1 Tat protein in a GFAP-regulated, doxycycline-inducible manner, we assessed morphine tolerance, dependence, and reward. To assess the influence of CCR5 on these effects, mice were pretreated with oral vehicle or the CCR5 antagonist, maraviroc, prior to morphine administration...

Decreases in children's anger reactivity because of the onset of their autonomous use of strategies characterizes the prevailing model of the development of emotion regulation in early childhood (Kopp, 1989). There is, however, limited evidence of the varied pathways that mark this development and their proposed antecedents and consequences. This study used a person-centered approach to identify such pathways, antecedents, and outcomes. A sample of 120 children from economically strained rural and semirural households were observed while waiting to open a gift at ages 24, 36, and 48 months...

Physical forces associated with tumor growth and drainage alter cancer cell invasiveness and metastatic potential. We previously showed that fluid frictional force, or shear stress, typical of lymphatic flow induces YAP1/TAZ activation in prostate cancer cells to promote motility dependent upon YAP1 but not TAZ. Here, we show that shear stress elevates TAZ protein levels and promotes TAZ nuclear localization. Increased TAZ activity drives increased DNA synthesis and induces AMOTL2, ANKRD1, and CTGF gene transcription independently of YAP1...

BACKGROUND: The multiplex, lattice mosaic of cone photoreceptors in the adult fish retina is a compelling example of a highly ordered epithelial cell pattern, with single cell width rows and columns of cones and precisely defined neighbor relationships among different cone types. Cellular mechanisms patterning this multiplex mosaic are not understood. Physical models can provide new insights into fundamental mechanisms of biological patterning. In earlier work, we developed a mathematical model of photoreceptor cell packing in the zebrafish retina, which predicted that anisotropic mechanical tension in the retinal epithelium orients planar polarized adhesive interfaces to align the columns as cone photoreceptors are generated at the retinal margin during post-embryonic growth...

BACKGROUND: Histone deacetylases (HDACs) are a group of histone modification enzymes with pivotal role in disease pathogenesis especially in cancer development. Increased activity of certain types of HDACs and positive effects of HDAC inhibition has been shown in several types of cancers. Furthermore, few HDAC inhibitors have been approved by the FDA for cancer treatment, and this has generated interest in finding new HDAC inhibitors as potential anti-cancer agents. Curcumin, a natural polyphenol extracted from turmeric, is a safe and bioactive phytochemical with a wide range of molecular targets and pharmacological activities including promising anti-cancer properties...

Patients with muscle-invasive bladder cancer (MIBC) have poorer prognoses if cancer has metastasized to the lymph nodes. Genomic markers of lymph node involvement (LNI) would be useful for treatment planning, especially if measured at the biopsy stage, but large-scale studies of tumor tissue at any stage are needed to discover robust markers of LNI. We performed a genome-wide query of copy number alterations (CNA) in 237 MIBC surgical tumor specimens from patients in The Cancer Genome Atlas who had radical cystectomy and lymphadenectomy without neoadjuvant treatment...

INTRODUCTION: Overactive bladder (OAB) and urinary incontinence are common problems that have significant impact on quality of life (QOL). Less than half of sufferers seek help from their physicians; many who do are dissatisfied with treatment and their physicians' understanding of their problems. Little is known about the sociolinguistic characteristics of physician-patient communication about OAB in community practice. METHODS: An IRB-approved observational sociolinguistic study of dialogues between patients with OAB and treating physicians was conducted...

Compared to their rural non-farming peers, farmers are less likely to access preventive healthcare services; however, the reasons for this disparity are poorly understood. We conducted semi-structured interviews with a total of 30 farm household members in central New York. Interview topics included farming identity, perceptions of one's health, past experiences with acute and preventive healthcare, and attitudes toward seeking healthcare services. Grounded Theory analysis of the interview transcripts revealed that (1) utilizing healthcare services is felt to be in conflict with the farming identity, (2) the need to conserve time and money for farm applications poses a barrier to healthcare utilization, (3) farmers decide to seek healthcare when they believe it is necessary to ensure survival of the farm, and (4) the decision to seek healthcare is most strongly driven by the presence of intolerable symptoms, prompting from others, and the perception that treatment will yield clear benefits...

As health care organizations seek to be highly reliable, systems that include layers of redundancy have been created to protect patients from harm. Many of these layers of protection are dependent on nurses making a decision to follow or adhere to the human aspects of the process. Because these decisions begin with a perception and identification of risk, understanding what nurses perceive to be a risk to patients is an essential part of designing safer health care systems. The purposes of this qualitative study were to (1) describe what nurses perceive as risky to patients in common nursing practice situations, (2) describe the effects of the perceptions of risk on clinical decision making and behavior, and (3) identify what factors nurses perceive as increasing or decreasing risk...
