Placebo-controlled clinical trials have led to concern over possible
increased risk of suicide-related events in some populations exposed to
To evaluate the risk of suicide attempts by antidepressant drug class and
the presence or absence of depression.
A retrospective propensity-matched new-user cohort study was used to
compare participants with incident depression classified by
antidepressant treatment with each other and with the general
Among the treated group, the suicide attempt rate peaked in the month
prior to diagnosis then decreased steadily over the next 6 months. Among
the pharmacologically untreated group, the highest rate was seen in the
second month after diagnosis. Cohorts with depression had significantly
higher suicide attempt risk than the general population, but the treated
group did not differ significantly from the untreated group.
Patients on antidepressants did not have significantly higher risk
compared with untreated patients. No significant differences were
observed for patients treated with individual serotonin–noradrenaline
reuptake inhibitors (SNRIs) or selective serotonin reuptake inhibitors
(SSRIs) or by class (SSRI v. SNRI cohorts).
The objective is to describe the prevalence and nature of painful symptoms among depressive outpatients and how are they related with depressive symptoms and somatic non painful symptoms at baseline.
The FINDER study, conducted in 12 European countries in depressed outpatients in routine primary and specialist care settings provides a unique opportunity to answer these questions.
Painful symptoms were evaluated among 3468 patients enrolled by 437 investigators, using the 28-item Somatic Symptom Inventory (SSI-28) and 6 Visual Analogue Scales (1 item on overall pain and 5 items on pain characteristics: headaches, back pain, shoulder pain, interferences with daily activities and pain while awake). There was a strong correlation between the VAS overall pain score and the pain sub score of the SSI-28. The threshold score of 30 mm on the overall pain severity in combination with selected comorbidities was used to divide patients in three pain cohorts: (1) those with no/mild pain; (2) those with moderate/severe œmedically explained pain and (3) those with moderate/severe medically unexplained pain.
Results showed that 1447 (43.7%) patients had no/mild pain, 550 (16,6%) had moderate/severe medically explained pain, and 1311 (39,6%) had moderate/severe medically unexplained pain. Of the different locations of pain symptoms (from the SSI-28), headaches were the most common, followed by muscle soreness and lower back pain. The mean depression score (HADS-D) was higher in patients with pain-related symptoms.
We studied the correlations between the measures of pain and depression. These results and their implications will be discussed.
The wetting behavior of perfluorinated ionomers has been investigated as a function of polymer-surface interaction, the nature of the counter-ion and the structure of the polymer in the solvent from which it has been cast onto the surface. Two different ion-containing polymers, with a per-fluoro-carbon backbone were studied. They differ in the chemical composition and the polarity of their side chains. AFM results together with neutron reflectivity, light scattering and surface tension measurements had shown that the structure of the polymer in the parent solution has a profound effect on the wetting properties as well as the surface structure of the polymers.
