    Administration of antidepressants - Single versus split dosing: a meta-analysis

    No full text
    Objective: To evaluate the literature comparing antidepressant effects of multiple daily dosing versus single daily dosing of antidepressants. Method: Studies comparing efficacy of single versus multiple daily dosing of antidepressants were reviewed. Data from the clinical trials meeting our inclusion criteria was subgrouped according to the half-life of the antidepressant drug studied. Meta-analyses were carried out to compare antidepressant efficacy of single versus multiple daily dosing overall and separately for the short. intermediate, and long half life antidepressant agent subgroups. Results: The review process identified 22 studies comparing the therapeutic effect of antidepressants according to their dosing schedules. Although most studies used antidepressant medications with short half-lives, none found a significant difference in therapeutic efficacy. Furthermore. the improvement rates in depression scores in between the two groups were almost identical (SDD versus MDD). Conclusion: This meta-analytic approach found no advantage for multiple daily dosing and suggests that sustained therapeutic serum levels are not necessary for achievement of therapeutic activity. Antidepressant benefit may simply require a limited duration of exposure above the threshold serum level. Administration of antidepressants in single daily doses appears sufficient to perturb the physiological pathways associated with depression sufficiently to achieve an adaptive therapeutic response. Moreover, a single daily dosing regimen offers the potential advantages of simplicity, increased compliance, and reduced adverse effects, which in turn would increase the overall success rate in treatment of depression.

    Bloodstream infections caused by Staphylococcus aureus in a university hospital in Turkey: clinical and molecular epidemiology of methicillin-resistant Staphylococcus aureus

    In total, 177 patients with bloodstream infections caused by Staphylococcus aureus (BSISA) were investigated prospectively between June 1999 and June 2001. Of these, 19.8% had community-acquired BSISA, while 80.2% had nosocomial BSISA. Surgical intervention, foreign body, mechanical ventilation, total parenteral nutrition, and previous antibiotic treatment were found to be important risk factors for the nosocomial BSISA group. Secondary BSISA formed a greater proportion (62.9%) of community-acquired infections than of nosocomial infections (26.8%; p 0.0001). Catheter-related nosocomial BSISA was observed in 72.1% of patients. The suppurative complication rate was significantly higher among community-acquired infections (22.9%) than among nosocomial infections (6.3%; p 0.008). Of the nosocomial BSISA, 65.5% were methicillin-resistant. Analysis of 80 methicillin-resistant S. aureus isolates by pulsed-field gel electrophoresis identified ten main clones (A-J), but 61 (76.3%) of the 80 isolates belonged to clone A

    Right Coronary Artery Arising from the Pulmonary Trunk

    The prevalence of coronary artery anomalies is reported to be around 0.3-1%. An anomalous origin of the right coronary artery (RCA) is a rare condition but may lead to myocardial ischemia. and sudden death. Diagnosis is mainly made by conventional. coronary arteriography. Nowadays, multislice computed tomography is a new noninvasive imaging technique with excellent: spatial resolution which can detect the origin and course of an. anomalous coronary vessel. Here we report on a 67-year-old woman with an anomalous origin of the RCA arising from the pulmonary trunk. The anomaly was diagnosed by cardiac catheterization and confirmed by multislice computed tomography

    Evidence-based guidelines for treating depressive disorders with antidepressants: A revision of the 2000 British Association for Psychopharmacology guidelines

    No full text
    A revision of the 2000 British Association for Psychopharmacology evidence based guidelines for treating depressive disorders with antidepressants was undertaken to incorporate new evidence and to update the recommendations where appropriate. A consensus meeting involving experts in depressive disorders and their management was held in May 2006. Key areas in treating depression were reviewed, and the strength of evidence and clinical implications were considered. The guidelines were drawn up after extensive feedback from participants and interested parties. A literature review is provided, which identifies the quality of evidence to inform the recommendations, the strength of which are based on the level of evidence. These guidelines cover the nature and detection of depressive disorders, acute treatment with antidepressant drugs, choice of drug versus alternative treatment, practical issues in prescribing and management, next-step treatment, relapse prevention, treatment of relapse, and stopping treatment
