Inflammatory bowel disease patient perceptions of diagnostic and monitoring tests and procedures.

Background: Inflammatory Bowel Disease (IBD) with its high incidence and prevalence rates in Canada generates a heavy burden of tests and procedures. The purpose of this study is to gain a better understanding of the transfer of information from physician to patient, as well as the patient understanding and perceptions about the tests and procedures that are ordered to them in the context of IBD diagnosis and monitoring.

Methods: An online questionnaire was completed by 210 IBD patients in Canada.

Exploring the Use of a Participative Design in the Early Development of a Predictive Test: The Importance of Physician Involvement.

In this study, we contribute to the personalized medicine and health care management literature by developing and testing a new participative design approach. We propose that involving gastroenterologists in the development of a predictive test to assist them in their clinical decision-making process for the treatment of inflammatory bowel diseases will increase the likelihood of their acceptance of the innovation. Based on data obtained from 6 focus groups across Canada from a total of 28 physicians, analyses reveal that current tools do not enable discriminating between treatment options to find the best fit for each patient.

Patients' perception of their involvement in shared treatment decision making: Key factors in the treatment of inflammatory bowel disease.

Objectives: This study aims to characterize the relationships between the quality of the information given by the physician, the involvement of the patient in shared decision making (SDM), and outcomes in terms of satisfaction and anxiety pertaining to the treatment of inflammatory bowel disease (IBD).

Methods: A Web survey was conducted among 200 Canadian patients affected with IBD. The theoretical model of SDM was adjusted using path analysis.

Effects of ASM-024, a modulator of acetylcholine receptor function, on airway responsiveness and allergen-induced responses in patients with mild asthma.

Objectives: To evaluate the safety, tolerability and clinical activity of ASM-024, a new cholinergic compound with dual nicotinic and muscarinic activity, in mild allergic asthma.

Methods: The present study involved 24 stable, mild allergic asthmatic subjects. In a cross-over design, ASM-024 (50 mg or 200 mg) or placebo were administered once daily by nebulization over three periods of nine consecutive days separated by a three-week washout.

Dehydroascorbic acid normalizes several markers of oxidative stress and inflammation in acute hyperglycemic focal cerebral ischemia in the rat.

We investigated the effect of dehydroascorbic acid (DHA), the oxidized form of vitamin C which is a superoxide scavenger, on manganese superoxide dismutase (MnSOD), copper-zinc SOD (CuZnSOD), cyclooxygenase-2 (COX-2) and interleukin-1beta (IL-1beta) expression in a rat model of focal cerebral ischemia under normo- and hyperglycemic conditions. Edema formation was also assessed. MnSOD, CuZnSOD, COX-2 and IL-1beta mRNA and protein expression were studied 3 h post-ischemia.

Expression of superoxide dismutase in hyperglycemic focal cerebral ischemia in the rat.

This study investigated the possibility that hyperglycemia induces early expression of various superoxide dismutases (SOD) and nitric oxide synthases (NOS) following focal cerebral ischemia in the rat. MnSOD, CuZnSOD, nNOS and eNOS mRNA and protein expression were examined 3 h after permanent middle cerebral artery occlusion under acute hyperglycemic or normoglycemic conditions. 2,3,5-triphenyltetrazolium chloride (TTC) treatment post-mortem revealed a significant area at risk of infarction following ischemia in hyperglycemic compared to normoglycemic rats.

Decreased beta-actin mRNA expression in hyperglycemic focal cerebral ischemia in the rat.

beta-Actin is often used as a housekeeping gene when performing reverse transcription-polymerase chain reaction (RT-PCR) analysis for cerebral ischemia models. In the present study, we tested two different control genes used for RT-PCR experiments, beta-actin and porphobilinogen deaminase (PBG-D), in a rat model of focal cerebral ischemia under normo- or hyperglycemic conditions. A three-vessel occlusion model with permanent middle cerebral artery occlusion was used in the rat.

Phase 1/2 pilot study of methotrexate-laurocapram topical gel for the treatment of patients with early-stage mycosis fungoides.

Objectives: To assess the safety and tolerability of a topical gel formulation combining methotrexate and laurocapram and to obtain preliminary information on the therapeutic potential of methotrexate-laurocapram in patients with early-stage mycosis fungoides (stage IA or IB).

Design: An open-label, phase 1/2 pilot study.

Setting: Two academic referral centers.
