Some adolescents in the United States who have been abused and/or neglected by caregivers and placed in permanent custody of the state leave, or "age out" of foster care at 18 years of age. Poor health outcomes among individuals who age out are notable, yet few studies describe the phenomenon of seeking healthcare services after leaving foster care. The investigators specifically queried the phenomenon of seeking healthcare services after foster care drawing from the Phenomenology of Practice approach...

The current study investigated the mediating role of phosphodiesterase type 4 (PDE4) regulated cAMP in the dopaminergic modulation of premature responding (action restraint) in rats. Response inhibition, which includes action restraint, finds its neurobiological origin in cortico-striatal-thalamic circuitry and can be modulated by dopamine. Intracellularly, the effect of dopamine is largely mediated through the cAMP/PKA signaling cascade. Areas in the prefrontal cortex are very sensitive to their neurochemical environment, including catecholamine levels...

Paula M Conroy, Maurice G O'Sullivan, Ruth M Hamill, Joseph P Kerry
The properties of varying salt and fat levels in traditional breakfast sausages were investigated. Sausages were produced with fat levels of: 30%, 20% and 15%. Fat was replaced with pea extract. Salt levels employed were: 2.5%, 1.1% and 0.0%. A reduced sodium salt which contains 45% less sodium than standard salt was used. Sensory analysis was conducted on consumers (n = 228): 18-40 yrs., 41-64 yrs. and 65-85 yrs. The 18-40 yr. olds preferred sausages containing 20% fat, 41-64 yr. olds preferred sausages with 15% fat, 65+ age group preferred sausages containing 30% fat...

BACKGROUND: Older patients have frailty characteristics that impair the transposition of treatment results found in younger patients. Predictive factors are needed to help with treatment choices for older patients. The PRODIGE 20 study is a randomized phase II study that evaluated chemotherapy associated with bevacizumab (BEV) or not (CT) in patients aged 75 years or older. PATIENTS AND METHODS: Patients underwent a geriatric assessment at randomization and at each evaluation...

OBJECTIVES: Erythropoiesis-stimulating agents (ESAs) remain first-choice to treat symptomatic anemia and delay transfusion dependence in most patients with lower-risk myelodysplastic syndromes (MDS) without del(5q). Deferasirox increased erythroid responses in some lower-risk MDS patients in clinical trials, and adding low-dose deferasirox to ESA treatment may further improve erythroid response. METHODS: KALLISTO (NCT01868477) was a randomized, open-label, multicenter, phase II study...

For coupled oscillator networks with Laplacian coupling, the master stability function (MSF) has proven a particularly powerful tool for assessing the stability of the synchronous state. Using tools from group theory, this approach has recently been extended to treat more general cluster states. However, the MSF and its generalizations require the determination of a set of Floquet multipliers from variational equations obtained by linearization around a periodic orbit. Since closed form solutions for periodic orbits are invariably hard to come by, the framework is often explored using numerical techniques...

Antonello A Barresi, Valeria Rasetto, Daniele L Marchisio
This manuscript shows how computational models, mainly based on Computational Fluid Dynamics (CFD), can be used to simulate different parts of an industrial freeze-drying equipment and to properly design them; in particular, the freeze-dryer chamber and the duct connecting the chamber with the condenser, with the valves and vanes eventually present are analysed in this work. In Part 1, it will be shown how CFD can be employed to improve specific designs, to perform geometry optimization, to evaluate different design choices and how it is useful to evaluate the effect on product drying and batch variance...

The purpose of the present study is to investigate the concordance of treatment preferences between patients and physicians in prostate cancer (PCa) in Japan. An internet-based discrete choice experiment was conducted. Patients and physicians were asked to select their preferred treatment from a pair of hypothetical treatments consisting of four attributes: quality of life (QOL), treatment effectiveness, side effects, and accessibility of treatment. The data were analyzed using a conditional logistic regression model to calculate coefficients and the relative importance (RI) of each attribute...

In this study we investigate the decision problem of a central authority in pickup and delivery carrier collaborations. Customer requests are to be redistributed among participants, such that the total cost is minimized. We formulate the problem as multi-depot traveling salesman problem with pickups and deliveries. We apply three well-established exact solution approaches and compare their performance in terms of computational time. To avoid unrealistic solutions with unevenly distributed workload, we extend the problem by introducing minimum workload constraints...

In within-study comparison (WSC) designs, treatment effects from a nonexperimental design, such as an observational study or a regression-discontinuity design, are compared to results obtained from a well-designed randomized control trial with the same target population. The goal of the WSC is to assess whether nonexperimental and experimental designs yield the same results in field settings. A common analytic challenge with WSCs, however, is the choice of appropriate criteria for determining whether nonexperimental and experimental results replicate...

BACKGROUND: Breast cancer (BC) patients with ipsilateral breast tumor recurrence (IBTR) are at high risk of developing distant metastases (DM). We aimed to evaluate the risk pattern of developing DM, with respect to the occurrence of IBTR, in a large series of patients homogeneously treated by conservative surgery (QUART) with a considerably long follow-up. METHODS: Piecewise exponential model was used to investigate DM dynamics conditioning on known prognostic factors and IBTR occurrence as time dependent covariate...

OBJECTIVE: The choice between primary debulking surgery (PDS) and neoadjuvant chemotherapy (NAC) in advanced ovarian cancer remains controversial. We evaluated NAC use in our center before and after results from a randomized trial were published, with the aim to determine the impact of changes in the neoadjuvant strategy on survival in advanced-stage ovarian cancer. METHODS: We retrospectively investigated the clinical course of 435 patients with ovarian, tubal, or peritoneal carcinoma (International Federation of Gynecology and Obstetrics [FIGO] stage III or IV)...

Porous hydroxyapatite (HAp) nanorods using surfactant templating proceeded via microwave irradiation method. Study of BET surface area measurement of the HAp nanorods showed that surface area of HAp nanorods with a mixture of cat-anionic surfactants was higher (56.16 m2/g) than their individual counterpart (for anionic 52.8 m2/g and for cationic 48.8 m2/g) as well as without surfactant (19.07 m2/g) due to higher synergistic effect and low critical aggregation concentration of the mixture. Surfactant-directed synthesis of porous HAp has been explored in literature, but the relation between the pore size distribution, surface area and morphology and choice of surfactant(s) was not fully understood and hence in this work we have explored those parameters...

Experimental and survey research spanning the last two decades concludes that people who are more risk tolerant are more likely to engage in risky health activities such as smoking and heavy alcohol consumption, and are more likely to be obese. Subjective perceptions of the risk associated with different activities have also been found to be associated with health behaviors. While there are numerous studies that link risk perceptions with risky behavior, it is notable that none of these controls for risk aversion...

BACKGROUND: Uganda changed its antiretroviral therapy guidelines in 2014, increasing the CD4 threshold for antiretroviral therapy initiation from 350 cells/μl to 500 cells/μl. We investigate what effect this change in policy is likely to have on HIV incidence, morbidity, and programme costs, and estimate the cost-effectiveness of the change over different time horizons. METHODS: We used a complex individual-based model of HIV transmission and antiretroviral therapy scale-up in Uganda...

Among the renal cystic diseases that result in end-stage renal disease, an important hereditary cause is medullary cystic kidney disease, which affects adults in an autosomal dominant pattern. It is characterized by progressive renal failure, tubulointerstitial fibrosis, and formation of small cysts in the renal medulla and corticomedullary junction. While the appearance of medullary/corticomedullary cysts may not be pathognomonic for medullary cystic kidney disease, encountering a patient with renal failure and medullary/corticomedullary cysts should prompt further investigation, given the implication of having the disease...
