This study reported epidemiology and antimicrobial resistance data of BSIs in Japan and identified several risk factors associated with 30-day mortality. National surveillance of BSIs is required in Japan for comparison with other countries.
Moderate to severe migraine attacks are treated with triptans. However, about 25% of migraineurs fail to respond to triptans. We investigated the involvement of gene polymorphisms, personality traits and characteristics of headache, and made a scoring system for prediction of clinical response to triptans in patients with migraine. Gene polymorphisms including serotonin (5-HT)(1B) receptor G861C and dopamine receptor 2 (DRD2) C939T, personality traits and characteristics of headache were investigated in 46 consistent responders and 14 inconsistent responders to triptans. The multivariate stepwise logistic regression analysis revealed that age, periorbital/deep orbital pain and C/C genotype carrier at DRD2 C939T were significant factors that contributed independently to the negative response to triptans in patients with migraine. Their odds ratios were 6.329 (40-69 vs. 20-39 years, 95% CI 1.441-27.778), 6.772 (no vs. yes, periorbital/deep orbital pain, 95% CI 1.159-39.580) and 14.085 (non-C/C vs. C/C genotype at DRD2 C939T, 95% CI 1.253-166.667), respectively. The predictive index (PI) of clinical response to triptans in patients with migraine was calculated using these three factors. The score in inconsistent responders (1.6 ± 0.6) was significantly higher than that in consistent responders (0.8 ± 0.7, P < 0.001). Sensibility of low-score (RI = 0) group was 100%, and specificity of high-score (PI ≥ 2) group was 87%. The proposed scoring system should in the future be the object of larger studies to confirm its validity.
We have reported a rare case of lumbar metastasis of choriocarcinoma after a normal-term pregnancy. This is the first report of lumbar metastasis of choriocarcinoma treated by spinal surgery. Because surgical resection of a lumbar metastasis of choriocarcinoma involves a substantial risk of profuse hemorrhage, local recurrence and the spread of metastasis, multiagent chemotherapy in combination with radiotherapy should be preformed before surgical resection.
Migraine is a multifactorial disease with various factors, such as genetic polymorphisms and personality traits, but the contribution of those factors is not clear. To clarify the pathogenesis of migraine, the contributions of genetic polymorphisms and personality traits were simultaneously investigated using multivariate analysis. Ninety-one migraine patients and 119 non-headache healthy volunteers were enrolled. The 12 gene polymorphisms analysis and NEO-FFI personality test were performed. At first, the univariate analysis was performed to extract the contributing factors to pathogenesis of migraine. We then extracted the factors that independently contributed to the pathogenesis of migraine using multivariate stepwise logistic regression analysis. Using the multivariate analysis, three gene polymorphisms including monoamine oxidase A (MAOA) T941G, methylenetetrahydrofolate reductase (MTHFR) C677T, and tumor necrosis factor beta (TNF-β) G252Α, and the neuroticism and conscientiousness scores in NEO-FFI were selected as significant factors that independently contributed to the pathogenesis of migraine. Their odds ratios were 1.099 (per point of neuroticism score), 1.080 (per point of conscientiousness score), 2.272 (T and T/T or T/G vs G and G/G genotype of MAOA), 1.939 (C/T or T/T vs C/C genotype of MTHFR), and 2.748 (G/A or A/A vs G/G genotype of TNF-β), respectively. We suggested that multiple factors, such as gene polymorphisms and personality traits, contribute to the pathogenesis of migraine. The contribution of polymorphisms, such as MAOA T941G, MTHFR C677T, and TNF-β G252A, were more important than personality traits in the pathogenesis of migraine, a multifactorial disorder.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
