Opioid Safety Program in Pain Clinics (Op-Safe):

In this vital study, the investigators will develop an innovative Opioid Safety (Op-Safe) Program for use in pain clinics. The Op-Safe Program consists of two key components: Educating patients with an informative brochure and video developed by the Institute for Safe Medication Practices (ISMP) Canada, and a screening algorithm to identify unrecognized sleep apnea in patients taking opioids for chronic non-cancer pain.

Tamoxifen in Patients With Oesophageal Cancer

Cancer of the gullet (oesophagus) is a lethal disease in which only 15% of patients survive 5 years once diagnosed. It is more common in men than women, and men appear to have a worse prognosis. One suggestion for this gender difference is the sex hormone oestrogen, which exerts its effect via oestrogen receptors. The role of oestrogen in breast cancer is well described, and antioestrogen medication such as tamoxifen, which blocks oestrogen receptors are in widespread and effec...

Chidamide in Combination With Antiretroviral Therapy for Eradication of the Latent HIV-1 Reservoir

HIV replication can be effectively suppressed and acquired immunodeficiency syndrome(AIDS) can be prevented with highly active antiretroviral therapy (HAART). However, HIV-infected people must remain on treatment continuously to avoid viral rebound and progression to AIDS. HIV persistence is thought to stem primarily from the presence of integrated copies of the proviral genome within long-lived cells. Because active viral gene expression causes cell death due to viral cytopath...

Operative Procedures vs. Endovascular Neurosurgery for Untreated Pseudotumor Trial

Pseudotumor cerebri, also called idiopathic intracranial hypertension (IIH), is characterized by elevated intracranial pressure, headache, and if severe, vision loss. IIH is difficult to treat. Medical management may not adequately resolve the symptoms, and surgical management (primarily through cerebrospinal fluid [CSF] shunting) has a high failure rate. Recently, a relationship between IIH and stenosis of the dural venous sinuses (the veins that drain blood from the brain) ha...

The Effects of Different Kinds of Antihypertensive Drugs on Blood Pressure Variability in Northern Chinese

Hypertension is one of the most common cardiovascular diseases, which is a major risk factor for stroke and cardiovascular events. Traditionally, cardiovascular risk stratification in hypertensive patients was based on the average blood pressure (BP) measured in the clinic. Accumulated data has shown that target-organ damage is related not only to 24-h mean intra-arterial BP, but also to BP variability (BPV) in subjects with essential hypertension. Growing evidence demonstrated...

Influence of Testosterone Administration on Drug-Induced QT Interval Prolongation and Torsades de Pointes

Torsades de pointes (TdP) is a potentially fatal ventricular arrhythmia associated with corrected QT (QTc) interval prolongation. More than 50 commonly used drugs available on the US market may cause QTc interval prolongation and TdP. While TdP occurs more commonly in women, 33-45% of all cases of TdP have occurred in men. Older age is a risk factor for drug-induced TdP in men, possibly due to declining serum testosterone concentrations. Available evidence shows an inverse rela...

These drugs may attenuate the acute and/or chronic postoperative pain or decrease the analgesic requirements after surgery. The aim of the present study is to ...

Ictal SPECT With Intra-arterial Injection

Ictal SPECT with intravenous injection in a cubital vein of a perfusion tracer is an established technique to localize the ictal onset zone during presurgical evaluation of refractory focal epilepsy. When seizures last less than 10 seconds, localizing information is often not obtained. Since it takes around 30 seconds before the tracer reaches the brain after intravenous injection, ictal hyperperfusion most likely has already switched to postictal hypoperfusion. In this study, ...
