Chronic pain is associated with high levels of psychological distress, which can have implications for general functioning, acceptance, quality of life, and compliance with health-promoting behaviour. This study explored the association between pain-related factors and psychological distress in a sample of patients with long lasting temporomandibular disorder (TMD). In this cross-sectional study design, psychological distress was measured in 133 Norwegian patients with long lasting and severe TMD.

Aims: Radiotherapy (XRT) for cancer-induced bone pain (CIBP) has varying levels of efficacy. A biomarker that predicts likely efficacy could stratify XRT to those most likely to benefit. No biomarker is used in clinical practice, but potential candidate cytokines have been identified.

Objective: To show how a simple Bayesian analysis method can be used to improve the evidence base in patient populations where recruitment and retention are challenging.
Methods: A Bayesian conjugate analysis method was applied to binary data from the Thermal testing in Bone Pain (TiBoP) study: a prospective diagnostic accuracy/predictive study in patients with cancer-induced bone pain (CIBP). This study aimed to evaluate the clinical utility of a simple bedside tool to identify who was most likely to benefit from palliative radiotherapy (XRT) for CIBP.
Introduction: Cancer frequently spreads to bone, causing cancer-induced bone pain (CIBP) which affects quality of life. The best treatment is radiotherapy (XRT), but response is variable. The aim of this systematic review was to identify factors that predict analgesic response.
View Article and Find Full Text PDFBackground: Opioids are the foundation of treatment for cancer pain but can cause side-effects, one of the most common being nausea and vomiting, which can impair quality of life.
Objective: To evaluate the evidence for the management of opioid-induced nausea and vomiting. This systematic review was undertaken as part of an update of the European Association for Palliative Care's opioid guidelines.
Purpose: In 2005, the European Association for Palliative Care made recommendations for prognostic markers in advanced cancer. Since then, prognostic tools have been developed, evolved, and validated. The aim of this systematic review was to examine the progress in the development and validation of prognostic tools.

Purpose: Opioids are recommended for moderate to severe cancer pain; however, in patients with cancer, impaired renal function can affect opioid metabolism. The aim of this systematic review was to evaluate the current evidence for the use of opioids in cancer patients with renal impairment.
Methods: A systematic review was conducted and the following databases were searched: MEDLINE (1966 to 2015), EMBASE (1980 2015) and Cochrane Central Register of Controlled Trials (up to 2015).
Antimicrobial resistance has become a problem of epidemic proportions; however, patients believe antibiotics can treat any infection (National Committee for Quality Assurance [NCQA], 2011). Judicious prescribing practices are known to decrease antimicrobial resistance in the community (Centers for Disease Control [CDC], 2012). Primary care providers (PCPs) are in a position to change current prescribing practices and patient beliefs regarding antimicrobials.
View Article and Find Full Text PDFBackground And Purpose: An objective measure of pain relief may add important information to patients' self assessment, particularly after a treatment. The study aims were to determine whether measures of physical activity and/or gait can be used in characterizing cancer-induced bone pain (CIBP) and whether these biomarkers are sensitive to treatment response, in patients receiving radiotherapy (XRT) for CIBP.
Materials And Methods: Patients were assessed before (baseline) and 6-8weeks after XRT (follow up).

Objective: To assess the effect of structured counselling on women's contraceptive decisions and to evaluate gynaecologists' perceptions of comprehensive contraceptive counselling.
Methods: Belgian women (18-40 years old) who were considering using a combined hormonal contraceptive (CHC) were counselled by their gynaecologists about available CHCs (combined oral contraceptive [COC], transdermal patch, vaginal ring), using a comprehensive leaflet. Patients and gynaecologists completed questionnaires that gathered information on the woman's pre- and post-counselling contraceptive choice, her perceptions, and the reasons behind her post-counselling decision.

Although many studies on the mechanical properties of brain tissue exist, some controversy concerning the possible differences in mechanical properties of white and gray matter tissues remains. Indentation experiments are conducted on white and gray matter tissues of various regions of the cerebrum and on tissue from the thalamus and the midbrain to study interregional differences. An advantage of indentation, when compared to standard rheological tests as often used for the characterization of brain tissue, is that it is a local test, requiring only a small volume of tissue to be homogeneous.

The underlying hypothesis was that single-fraction and multiple-fraction regimens are equally effective.
Material And Methods: The present study reports on the Norwegian sub sample of an international large prospective-randomised multicentre study.
Several cues for cell proliferation, migration, and survival are transmitted through lipid rafts, membrane microdomains enriched in sphingolipids and cholesterol. Cells obtain cholesterol from the circulation but can also synthesize cholesterol de novo through the mevalonate/isoprenoid pathway. This pathway, however, has several branches and also produces non-sterol isoprenoids.

In view of the recent finding that in the human prostate cancer cell line LNCaP, overexpression of FAS can be largely attributed to constitutive activation of the phosphatidylinositol-3 (PI3) kinase/Akt kinase pathway, the activation status of the Akt pathway, and whether this activation coincides with increased FAS expression, was examined in clinical prostate cancer tissues. Using well-preserved frozen prostatic needle biopsies and a sensitive Envision detection technique, S473-phosphorylated Akt (pAkt) was found in 11/23 low-grade prostatic intraepithelial neoplasia (PIN) lesions, in all (36/36) high-grade PINs, and in all (86/86) invasive carcinomas.

Here, we took advantage of the ability of the cell-permeable nucleoside 5-aminoimidazole-4-carboxamide (AICA) riboside to increase the intracellular levels of AICA ribotide, an AMP analogue, mimicking a low energy status of the cell. Treatment of cancer cells with AICA riboside impeded lipogenesis, decreased protein translation, and blocked DNA synthesis.

Identifying the genes that are regulated by androgens represents a major step towards the elucidation of the mechanisms underlying the impact of androgens on prostate cancer cell biology and is an attractive approach to find novel targets for prostate cancer therapy. Among the genes that have been identified thus far, several genes encode lipogenic enzymes.

It plays a central role in the production of surfactant in fetal lungs, in the supply of fatty components of milk, and in the conversion and storage of energy in liver and adipose tissue. Remarkably high levels of FAS expression are found in the majority of human epithelial cancers.
View Article and Find Full Text PDFOne of the most common molecular changes in cancer cells is the overexpression of fatty acid synthase (FAS), a key metabolic enzyme catalyzing the terminal steps in the synthesis of long chain saturated fatty acids. As part of our efforts to elucidate the mechanisms responsible for FAS overexpression, we have addressed the question whether overexpression of FAS may be linked to the frequently observed inactivation of PTEN and subsequent activation of the phosphatidylinositol 3'-kinase (PI3k) pathway. Using LNCaP prostate cancer cells as an experimental paradigm of FAS-overexpressing PTEN-null cancer cells, we demonstrate that LY294002, an inhibitor of the PI3k pathway causes a dramatic decrease in FAS protein expression.
