Food insecurity has been associated with lower nutrient intake as well as lower intake of fruits and vegetables. However, little is known about the association of food insecurity and dietary behaviors, including food choices and preparation methods. This study examines the relationship between food insecurity and dietary behaviors of low-income adults (N = 1,874; 55% Hispanic) who completed the baseline telephone survey for a nutrition education study.

Moreover, recent studies have indicated that chronic sFlt-1 excess causes hypertension in pregnant animals. The purpose of this study was to evaluate the role of ROS in mediating sFlt-1-induced hypertension in the pregnant rat.

Materials And Methods: Institutional ethics committee approval and informed consent were obtained. In two phase-III trials involving 51 patients with metastatic renal cell carcinoma (38 men, 13 women; age range, 30-80 years) receiving antiangiogenic drugs (sorafenib [n = 10], sunitinib [n = 22]), a placebo (n = 12), or interferon alfa (n = 7), serial dynamic contrast-enhanced CT was performed, during 90 seconds before and after injection of 80 mL of iobitridol.
Due to technical advances (parallel imaging and new phased-array coils), diffusion-weighted MR imaging can be used to image the female pelvis. Diffusion-weighted (b=1000) images are now acquired as a complement to conventional sequences (T2W, dynamic T1W images after intravenous injection of gadolinium). Diffusion weighted imaging improves the detection of small uterine tumors and the visualization of small implants of peritoneal carcinomatosis, which could play a significant role for tumor staging.

Background: This study examined mental health service use, minimal standards of treatment adequacy and correlates of service use and treatment adequacy for anxiety disorders in Canada.
Method: Data were drawn from the Canadian Community Health Survey: Mental Health and Well-Being (CCHS 1.2, 2002).
Genetic or epigenetic inactivation of the pathway formed by the Fanconi Anemia (FA) proteins occurs in several cancer types, including head and neck squamous cell carcinomas (HNSCC), rendering the affected tumors potentially hypersensitive to DNA crosslinking agents. However, the cytotoxicity of other commonly used cancer therapeutics in cells with FA pathway defects remains to be defined. Here, we focused on the effects of cisplatin and oxaliplatin in a panel of HNSCC and fibroblast cell lines.

We sought to determine a threshold for the computed tomography evaluation of these patients' best reflecting patient outcome.
Patients And Methods: In 334 mRCC patients treated with sunitinib, we tested thresholds from -45% to +10%.
Background: Inflammatory cytokines such as tumor necrosis factor-alpha (TNF-alpha) may be an important link between placental ischemia and hypertension in preeclampsia. We examined the effect of 17-hydroxyprogesterone caproate (17-OHP) on TNF-alpha-stimulated endothelin (ET) production and hypertension during pregnancy.
Methods: TNF-alpha-stimulated ET was examined from endothelial cells cultured in the presence and absence of progesterone.

Participants (N = 426) were recruited from a survey conducted in 1999 about clients' utilization of resources intended for homeless people in Montreal and Quebec. Data analyzed in this study were also drawn from three administrative databanks managed by the Quebec health care system.

With concurrent reforms affecting the overall layout of the health care system, the Action Plan especially seeks to improve the management of common mental disorders. This particular concern calls for transformations at the primary care level.

Your Healthy Life/Su Vida Saludable (YHL-SVS) was an intervention study with low income, ethnically diverse, English and Spanish-speaking participants to determine which methods of delivering tailored written nutrition materials were most effective in lowering fat and increasing fruit and vegetable (F&V) intake.
Methods: YHL-SVS was a randomized controlled trial with four experimental conditions: 1) Nontailored (NT) comparison group; 2) Single Tailored (ST) packet; 3) Multiple Tailored (MT) packet mailed in four installments; 4) Multiple Re-Tailored (MRT) MT packets re-tailored between mailings via brief phone surveys.
Purpose: Pancreatic metastasis accounts for 2% of metastatic renal cell carcinoma cases. Surgical management is typically recommended because of the limited value of immunotherapy as an effective treatment. Sunitinib recently showed clinical efficacy in patients with advanced renal cell carcinoma.

Data came from a survey of clientele of resources for homeless persons in Montreal and Quebec (N = 757) and this study includes the 369 people from this sample who met DSM-IV criteria for serious mental disorders at any point in their lifetime. A hierarchical logistic regression analysis was run with mental health service utilization in the past 12 months (dependent variable), and variables from Pescosolido's Model (independent variables).

Seventy-seven women (22-87 years old) with complex adnexal masses (30 benign and 47 malignant) underwent MR imaging including DWI before surgery. Conventional morphological MR imaging criteria were recorded in addition to b(1,000) signal intensity and apparent diffusion coefficient (ADC) measurements of cystic and solid components.

The objective of this study was to assess the impact, in terms of family satisfaction with end-of-life care, of a nursing home (NH) pilot educational program for nursing staff and physicians on comfort care and advanced dementia.
Methods: The intervention, implemented in one voluntary NH, consisted of an educational program that included providing an information booklet to all NH staff, and optionally to families.
Reductions in uterine perfusion pressure (RUPP) in pregnant rats is associated with increased tumor necrosis factor-alpha (TNF-alpha). This study was designed to determine the role of endogenous TNF-alpha in mediating changes in arterial pressure and endothelin-1 (ET-1) in RUPP rats. To achieve this goal we examined the effect of RUPP in the presence and absence of a TNF-alpha-soluble receptor, etanerecept (0.

Background: Depression is one of the most prevalent mental health problems worldwide with considerable social and economic burdens. While practice guidelines exist, their adherence is inconsistent in clinical practice.
Objective: To provide up-to-date national estimates of the adequacy of treatment received by Canadians having suffered a major depressive disorder (MDD) and examine factors associated with this adequacy.

Observers indicated the presence or absence of one or two features in a Gabor stimulus. When a pair of stimulus features differed in their speed of discrimination, responses indicating the presence of a conjunction were faster than those for the single feature for which discrimination was slowest (conjunction benefits).
