A course in constructing effective displays of data for pharmaceutical research personnel.

Interpreting data and communicating effectively through graphs and tables are requisite skills for statisticians and non-statisticians in the pharmaceutical industry. However, the quality of visual displays of data in the medical and pharmaceutical literature and at scientific conferences is severely lacking. We describe an interactive, workshop-driven, 2-day short course that we constructed for pharmaceutical research personnel to learn these skills.

Subgroup and resistance analyses of raltegravir for resistant HIV-1 infection.

Background: We evaluated the efficacy of raltegravir and the development of viral resistance in two identical trials involving patients who were infected with human immunodeficiency virus type 1 (HIV-1) with triple-class drug resistance and in whom antiretroviral therapy had failed.

Methods: We conducted subgroup analyses of the data from week 48 in both studies according to baseline prognostic factors. Genotyping of the integrase gene was performed in raltegravir recipients who had virologic failure.

Raltegravir with optimized background therapy for resistant HIV-1 infection.

Background: Raltegravir (MK-0518) is an inhibitor of human immunodeficiency virus type 1 (HIV-1) integrase active against HIV-1 susceptible or resistant to older antiretroviral drugs.

Methods: We conducted two identical trials in different geographic regions to evaluate the safety and efficacy of raltegravir, as compared with placebo, in combination with optimized background therapy, in patients infected with HIV-1 that has triple-class drug resistance in whom antiretroviral therapy had failed. Patients were randomly assigned to raltegravir or placebo in a 2:1 ratio.

Rofecoxib in patients with mild cognitive impairment: further analyses of data from a randomized, double-blind, trial.

A recent clinical trial in patients with Mild Cognitive Impairment (MCI) found an increased rate of possible or probable Alzheimer's disease (AD) diagnoses in patients assigned to rofecoxib compared to placebo. This unexpected finding was difficult to interpret due to methodological issues and a lack of confirmation on secondary endpoints, as well as a lack of confirmation in trials in related populations. We performed additional post hoc analyses to explore explanations for the finding based on possible neuropathological, cardiovascular/cerebrovascular, or cognitive effects of rofecoxib.

A randomized, double-blind, study of rofecoxib in patients with mild cognitive impairment.

Inflammatory mechanisms have been implicated in Alzheimer's disease (AD) and might be mediated via the COX-2 enzyme. Previous studies with the selective COX-2 inhibitors, rofecoxib and celecoxib, have shown that they do not alter the progression of AD. We conducted a double-blind study to investigate whether rofecoxib could delay a diagnosis of AD in patients with mild cognitive impairment (MCI), a group with an expected annual AD diagnosis rate of 10-15%.

Treatment comparisons for a partially categorical outcome applied to a biomarker with assay limit.

The plasma level of HIV-RNA has been shown to be a strong prognostic biomarker for clinical progression and death in HIV infected patients and is widely used as the primary outcome in clinical trials to evaluate antiretroviral treatments. Currently approved assays to measure HIV-RNA levels have a lower limit of reliable quantification (LoQ). Current regulatory guidelines recommend using the proportion of patients achieving HIV-RNA levels below the assay limit at a certain time point (e.

Incorporating durability information in the comparison of proportions of patients with HIV suppression.

In some HIV clinical trials, the proportion of patients who achieve treatment success at a clinically meaningful time point (e.g., 16 or 24 weeks) and the subsequent durability of the treatment success after that time point are collected from two exclusive followup intervals.

Acute pain management in patients with prior opioid consumption: a case-controlled retrospective review.

The patient with a history of current opioid consumption presenting in the acute postoperative setting presents a challenge for pain management. Standard treatment dosages and strategies are often ineffective in providing pain relief. This retrospective case-control study reviews 4 years' experience of the Acute Pain Service (APS) at our institution providing care for 202 chronic pain and opioid-consuming (CPOC) patients, 6.

Paralyzed with pain: the need for education.

This report surveyed the pharmacologic knowledge of the physician housestaff and intensive care nurses regarding the analgesic and anxiolytic effects of narcotics, benzodiazepines and neuromuscular blockers. The results demonstrated a commonly held misconception that muscular paralysis is a calm and painless state. The authors instituted an educational program stressing the need for analgesic and anxiolytic medications in conjunction with paralytic agents.
