189702. Searching the schizophrenic brain for temporal lobe deficits: a systematic review and meta-analysis. (PubMed)

Searching the schizophrenic brain for temporal lobe deficits: a systematic review and meta-analysis. Several empirical studies have found temporal lobe impairments in many patients with schizophrenia. The strength and consistency of this evidence, however, has not been evaluated and synthesized quantitatively. Hence, we ask to what extent are temporal cortices really defective in schizophrenia?Meta-analytical methods were used to determine the magnitude of evidence in support of structural

189703. Male circumcision and risk of HIV infection in sub-Saharan Africa: a systematic review and meta-analysis. (PubMed)

Male circumcision and risk of HIV infection in sub-Saharan Africa: a systematic review and meta-analysis. To systematically review studies of male circumcision and the risk of HIV-1 infection in men in sub-Saharan Africa, and to summarize the findings in a meta-analysis.A meta-analysis of observational studies.A systematic literature review was carried out of studies published up to April 1999 that included circumcision as a risk factor for HIV-1 infection among men in sub-Saharan Africa (...) . A random effects meta-analysis was used to calculate a pooled relative risk (RR) and 95% confidence interval (CI) for all studies combined, and stratified by type of study population. Further analyses were conducted among those studies that adjusted for potential confounding factors.Twenty-seven studies were included. Of these, 21 showed a reduced risk of HIV among circumcised men, being approximately half that in uncircumcised men (crude RR = 0.52, CI 0.40-0.68). In 15 studies that adjusted

189704. Calcium supplementation with calcium-rich mineral waters: a systematic review and meta-analysis of its bioavailability. (PubMed)

Calcium supplementation with calcium-rich mineral waters: a systematic review and meta-analysis of its bioavailability. The relevance of calcium (Ca2+), an essential bone mineral, to the prevention and treatment of osteoporosis is well established. However, a good deal of evidence casts doubt on the validity of current RDAs (recommended daily allowance), i.e., 800-1000 mg/day. New guidelines consistently advocate higher daily intakes (up to 1500 mg/day), a goal that may be difficult to achieve (...) identified, and, in a second step, studies comparing calcium absorption from mineral waters with that from dairy products. Four studies fulfilled all inclusion criteria. A meta-analysis based on published p values indicated calcium absorption from mineral waters was significantly higher (p = 0.03) than that from dairy products. Although only few studies with a relatively small number of subjects are available to date, the bioavailability of calcium from calcium-rich mineral waters thus seems

189711. Smoking and female infertility: a systematic review and meta-analysis. (PubMed)

Smoking and female infertility: a systematic review and meta-analysis. The high prevalence of smoking among women in their reproductive years continues to be a matter of concern. The negative effects of smoking on general health are well known, but smoking may also affect fertility. The objective of the present study was to perform a systematic review of the literature to determine whether there is an association between smoking and risk of infertility in women of reproductive age (...) , and to assess the size of this effect. In the 12 studies used for this meta-analysis, the overall value of the odds ratio (OR) for risk of infertility in women smokers versus non-smokers was 1.60 [95% confidence interval (CI) 1.34-1.91]. Studies of subfertile women undergoing in-vitro fertilization (IVF) treatment also show a reduction in fecundity among women smokers. A meta-analysis of nine studies found an OR of 0.66 (95% CI 0.49-0.88) for pregnancies per number of IVF-treated cycles in smokers versus

189714. The role of microvessel density on the survival of patients with lung cancer: a systematic review of the literature with meta-analysis. (PubMed)

The role of microvessel density on the survival of patients with lung cancer: a systematic review of the literature with meta-analysis. In order to determine whether angiogenesis is a prognostic marker in lung cancer, we performed a systematic review of the literature to assess the prognostic value on survival of microvessel count in patients with lung cancer. Published studies were identified by an electronic search in order to aggregate survival results, after a methodological assessment (...) median quality scores were respectively 52, 59 and 59% for studies assessing microvessel count via factor VIII, CD34 and CD31, without significant difference between studies evaluable or not for meta-analysis nor between studies with significant or non significant results. Seven 'factor VIII' studies, nine 'CD34' and seven 'CD31' provided sufficient data allowing a meta-analysis on survival and were evaluable for results aggregation. This showed that a high microvessel count in the primitive lung

189717. Systematic reviews of the literature: the overview and meta-analysis. (PubMed)

Systematic reviews of the literature: the overview and meta-analysis. Systematic reviews in the form of overviews or meta-analyses offer a solution for busy practitioners who have difficulty keeping abreast of current literature. Because systematic reviews can condense numerous studies into reliable and valid summaries of the best available evidence for a specific clinical problem, they offer significant benefit to busy clinicians. This article has summarized the major features and advantages (...) of systematic reviews. It has distinguished those features that attempt to increase the usefulness of reviews by limiting bias, and it provided a summary of important questions clinicians can use to appraise such reviews critically. With this knowledge, clinicians should be able to use the literature more appropriately and in a timely fashion.

189719. Residential proximity to electricity transmission and distribution equipment and risk of childhood leukemia, childhood lymphoma, and childhood nervous system tumors: systematic review, evaluation, and meta-analysis. (PubMed)

Residential proximity to electricity transmission and distribution equipment and risk of childhood leukemia, childhood lymphoma, and childhood nervous system tumors: systematic review, evaluation, and meta-analysis. In 1979, Wertheimer and Leeper reported an increased risk of cancer mortality among children living near 'electrical wiring configurations' suggestive of high current flow. Since then, numerous, often inconclusively small, investigations with conflicting results have studied (...) the possible association between exposure to electric and magnetic fields (EMF) and health effects. The high prevalence of exposure to EMF has drawn attention to the issue of carcinogenesis. We report here the results of a meta-analysis of 13 epidemiologic studies of residential proximity to electricity transmission and distribution equipment and risk of childhood leukemia, lymphoma, and nervous system tumors. The combined relative risks for leukemia, lymphoma, and nervous system tumors are 1.49 (95
