To compare the safety and antidepressant efficacy of paroxetine, imipramine, and placebo, data from six centres using the same protocol were pooled. A double-blind parallel-group design was used, with therapy lasting six weeks. From week 2 onwards, both the 240 paroxetine-treated and the 237 imipramine-treated patients were significantly different from the 240 placebo-treated patients, but no different from each other. Side-effects with paroxetine were less likely to lead to drop-out than with imipramine. Paroxetine had a possible earlier antidepressant effect than imipramine, and a possible earlier beneficial effect on anxiety symptoms associated with depression.

AbstractThe rapid cycling variant of bipolar disorder is defined as the occurrence of four periods of either manic or depressive illness within 12 months. Patients suffering from this variant of bipolar disorder have an unmet need for effective treatment. This review examines two major studies in an attempt to update understanding of the current therapies available to treat rapid cycling patients. The first trial compares lamotrigine versus placebo in 182 patients studied for 6 months. The second is a recently completed, 20-month trial comparing divalproate and lithium in 60 patients. Both trials had a double-blind, randomized parallel-group design. The data from the latter study indicate that there are no large differences in efficacy between lithium and divalproate in the long-term treatment of rapid cycling bipolar disorder. In addition, lamotrigine has the potential to complement the spectrum of lithium and divalproate through its greater efficacy for depressive symptoms.

The efficacy of quazepam (Sch-16134) 15 mg capsules as a hypnotic has been compared with that of placebo in a 9-day study, using a parallel-group design. The physician's global evaluation numerically favoured quazepam 63% (nineteen of thirty) over placebo 50% (fifteen of thirty). Furthermore, it demonstrated greater improvement in Hypnotic Activity Index and Sleep Quality Index from baseline scores, and caused no adverse reactions.

Promoting engagement in formal volunteering represents a potential means of facilitating healthy aging. Given reluctance to participate in volunteering has been partially attributed to negative perceptions of various aspects of this activity, this study assessed whether trialing volunteering can improve perceptions among older people. Using a parallel-group design, Australians aged 60+ years ( n = 445) were randomly assigned to one of two conditions, one in which they were encouraged to trial volunteering and one in which they were asked to continue their usual activities. Perceptions and attitudes among those in the volunteering condition became significantly more favorable over 6 months relative to those in the control condition, with this change predicted by several aspects of the volunteering experience (e.g., acquisition of skills, increased social connectedness). Providing access to roles that cater to the learning and social needs of older adults appears to be important for improving attitudes toward engaging in volunteer work.

Emerging syntheses and findings of new metallic nanoparticles (MNPs) have become an important aspect in various fields including diagnostic imaging. To date, iodine has been utilized as a radiographic contrast medium. However, the raise concern of iodine threats on iodine-intolerance patient has led to search of new contrast media with lower toxic level. In this animal modeling study, 14 nm iron oxide nanoparticles (IONPs) with silane-polyethylene glycol (SiPEG) and perchloric acid have been assessed for toxicity level as compared to conventional iodine. The nanotoxicity of IONPs was evaluated in liver biochemistry, reactive oxygen species production (ROS), lipid peroxidation mechanism, and ultrastructural evaluation using transmission electron microscope (TEM). The hematological analysis and liver function test (LFT) revealed that most of the liver enzymes were significantly higher in iodine-administered group as compared to those in normal and IONPs groupsP<0.05. ROS production assay and lipid peroxidation indicator, malondialdehyde (MDA), also showed significant reductions in comparison with iodine groupP<0.05. TEM evaluation yielded the aberration of nucleus structure of iodine-administered group as compared to those in control and IONPs groups. This study has demonstrated the less toxic properties of IONPs and it may postulate that IONPs are safe to be applied as radiographic contrast medium.
