[SSRIs and depressive symptoms in schizophrenia: a systematic review]. / SSRI's en depressieve klachten bij schizofrenie: een systematische review.

BACKGROUND: Patients with schizophrenia frequently have depressive symptoms. Current guidelines do not provide specific recommendations regarding the treatment of these symptoms, nor do they mention the role that selective serotonin reuptake inhibitors (ssris) can play in the treatment.
AIM: To investigate whether ssris are more effective than placebo in treating depressive symptoms in patients with schizophrenia.
METHOD: We searched the literature systematically using PubMed, embase, Cochrane Library and Psycinfo. We selected articles on the basis of inclusion and exclusion criteria and the methodologies used and compared the severity of patients symptoms before and after treatment.
RESULTS: We found only four published studies of randomised, double blind, placebo-controlled trials. These showed that an ssri was significantly more effective than a placebo (the difference being 0.4 - 6.7 points on the Hamilton Depression Rating Scale and 0.2 - 2.6 on the Calgary Depression Scale for Schizophrenia).
CONCLUSION: There are indications that ssris are effective for the treatment of depressive symptoms in patients with schizophrenia. However, the total sample size was limited and individual studies had several methodological limitations.

Colorectal cancer screening participation: a systematic review.

BACKGROUND: Colorectal cancer (CRC) is one of the most common cancers in men and women. CRC screening programmes have been implemented in various countries. However, the participation rate remains disappointingly low. For a screening method to be beneficial, high participation rates are essential. Therefore, understanding the factors that are associated with CRC screening and follow-up adherence is necessary. In this systematic review, factors studied in literature were identified that are associated with CRC screening adherence. METHODS: A systematic search in PUBMED, EMBASE and COCHRANE was performed to identify barriers and facilitators for CRC screening adherence. Study characteristics were summarized and analysed. RESULTS: Seventy-seven papers met the inclusion criteria to be applicable for review. Female gender, younger participants, low level of education, lower income, ethnic minorities and not having a spouse were the most frequently reported barriers. Health provider characteristics, such as health insurance and a usual source of care were also frequently reported barriers in CRC screening adherence. Disparities were found in weight, employment status and self-perceived health status. CONCLUSION: Barriers and facilitators of CRC screening participation are frequently reported. Understanding these factors is the first step to possibly modify specific factors to increase CRC screening participation rate.
