Meta AnalysisRelationship between pain relief and improvements in patient function/quality of life in patients with painful diabetic peripheral neuropathy or postherpetic neuralgia treated with pregabalin.
In patients with chronic pain due to diabetic peripheral neuropathy (DPN) or postherpetic neuralgia (PHN), pregabalin treatment results in pain relief and improved patient function/quality of life (QoL). Few studies, however, have examined the exact relationship between pain relief and improvements in patient function/QoL. It is unclear, for example, whether pregabalin has a direct independent effect on patient function/QoL or whether improvements in function/QoL are an indirect consequent of pain relief. ⋯ In patients with chronic pain due to DPN or PHN, improvements in patient function/QoL in response to pregabalin treatment are correlated with the extent of pain relief. However, such improvements in function/QoL are not mediated entirely through pain relief but are the result of a combination of pregabalin's effects on pain and sleep disturbance and a direct effect on patient function itself.

Randomized Controlled Trial Comparative StudyEffects of injectable HPβCD-diclofenac on the human delayed rectifier potassium channel current in vitro and on proarrhythmic QTc in vivo.
Novel formulations and administration routes of established drugs may result in higher maximum concentrations or total exposures and potentially cause previously unrecognized adverse events. ⋯ The findings from the present study suggest that HPβCD-diclofenac does not have a dose-dependent effect in the in vitro hERG assay system and does not produce proarrhythmic QTc prolongation in vivo. ClinicalTrials.gov identifier: NCT01812538.

When allergy or hypersensitivity and anaphylactic or anaphylactoid insults lead to cardiovascular symptoms and signs, including acute coronary events, the result might be the recently defined nosologic entity Kounis syndrome. Vasospastic allergic angina, allergic myocardial infarction, and stent thrombosis with occluding thrombus infiltrated by eosinophils and/or mast cells are the 3 reported variants of this syndrome. ⋯ The 3 reported variants of Kounis syndrome-vasospastic allergic angina, allergic myocardial infarction, and stent thrombosis with occluding thrombus-are caused by inflammatory mediators. Agents that inhibit mast-cell degranulation may be efficacious in preventing the acute coronary and cerebrovascular events of Kounis syndrome.

Budget impact analysis of tapentadol extended release for the treatment of moderate to severe chronic noncancer pain.
Opioids are commonly used to manage chronic pain. Although traditional μ-opioids are effective in reducing pain, they are often associated with opioid-induced side effects (OISEs) that can limit treatment effectiveness. Studies have shown that tapentadol extended release (ER) has a lower incidence of gastrointestinal adverse events than oxycodone controlled release (CR) at equianalgesic doses. ⋯ Our results suggest that replacing 10% of oxycodone CR's formulary share with tapentadol ER would decrease the overall budget of a health plan with 500,000 members. Placing tapentadol ER on a health plan formulary may result in a reduction in both pharmacy and medical costs.

Illness, particularly when severe, leads to increased concentrations of counter-regulatory factors which induce insulin resistance and predispose patients to stress hyperglycemia. Elevated glucose concentrations are common in hospitalized patients, both those with as well as without recognized diabetes. Substantial data has emerged over the past decade that quality glucose management in these individuals actually improves clinical outcomes. ⋯ In the intensive care setting, insulin infusions are now widely endorsed to quickly achieve and maintain glucose control. On the hospital wards, physiological subcutaneous insulin therapy, incorporating both basal and nutritional components, is emerging as the optimal treatment strategy. The transition to outpatient care is another important aspect of any hospital glycemic management program.
