Male factor infertility affects 30%-50% of infertile couples worldwide, and there is an increasing interest in the optimal management of these patients. In studies comparing double and single intrauterine insemination （IUI）, a trend towards higher pregnancy rates in couples with male factor infertility was observed. Therefore, we set out to perform a meta-analysis to examine the superiority of double versus single IUI with the male partner＇s sperm in couples with male factor infertility. An odds ratio （OR） of 95% confidence intervals （CIs） was calculated for the pregnancy rate. Outcomes were analysed by using the ManteI-Haesel or DerSimonian-Laird model accordingto the heterogeneity of the results. Overall, five trials involving 1125 IUI cycles were included in the meta-analysis. There was a two-fold increase in pregnancies after a cycle with a double IUI compared with a cycle with a single IUI （OR. 2.0; 95% CI. 1.07-3.75; P〈O.03）. Nevertheless, this result was mainly attributed to the presence of a large trial that weighted as almost 50% in the overall analysis. Sensitivity analysis, excluding this large trial, revealed only a trend towards higher pregnancy rates among double IUI cycles （OR. 1.58; 95% CI. 0.59-4.21）, but without statistical significance （P=0.20）. Our systematic review highlights that the available evidence regarding the use of double IUI in couples with male factor infertility is fragmentary and weak. Although there may be a trend towards higher pregnancy rates when the number of IUIs per cycle is increased, further large and well-designed randomized trials are needed to provide solid evidence toide current clinical practice.

Ferrimagnetic ceramic adsorbents for cleanup of H_2S from exhaust gases

引用

China Particuology 2007年第1期5卷 156-161页

作者： Bernd Halbedel apostolos Kontogeorgakos Institute of Materials Science Glass and Ceramic Technology Group Technische Universitt Ilmenau P.O. Box 10 05 65 D-98684 Ilmenau Germany NCSR "Demokritos" Institute of Materials Science 15310 Aghia Paraskevi Attiki Greece

Adsorbents that exhibit magnetic properties in addition to other required process-relevant characteristics open up new perspectives for the dry reduction and/or elimination of HES and other sulfur compounds from exhaust gases. These adsorbents eliminate the sulfur compounds from exhaust gases by virtue of their coatings and their magnetic property which makes it possible the use of magnetically assisted and stabilized fluidization in an externally applied magnetic field. In the present paper, the feasibility of the sorptive function of porous ceramic ferrimagnetic beads is ensured by sol-gel coating of zinc oxide without the formation of Zn-Fe-oxides and without considerable decrease of available pore volume. The results of material characterization by SEM, Auger electron spectroscopy, X-ray and mercury-porosity measurements and the loading capacity of a HES/N2 model gas are presented and discussed. The resulting HES loading of the functionalized adsorbent beads is more than 10 times larger than that of the starting material. @ 2007 Chinese Society of Particuolo^v and Institute of Process Engineering, Chinese Academy of Sciences.

Upfront surgery of small intestinal neuroendocrine tumors. Time to reconsider?

引用

World Journal of Gastroenterology 2018年第29期24卷 3201-3203页

作者： Kosmas Daskalakis apostolos V Tsolakis Department of Surgical Sciences Uppsala University Department of Oncology and Pathology Karolinska Institute Cancer Center Karolinska Karolinska University Hospital Solna R8:04 Department of Gastrointestinal Endoscopy Karolinska University Hospital Huddinge

Small intestinal neuroendocrine tumors(SI-NETs) may demonstrate a widely variable clinical behavior but usually it is indolent. In cases with localized disease, locoregional resective surgery(LRS) is generally indicated with a curative intent. LRS of SI-NETs is also the recommended treatment when symptoms are present, regardless of the disease stage. Concerning asymptomatic patients with distant metastases, prophylactic LRS has been traditionally suggested to avoid possible future complications. Even the current European Neuroendocrine Tumor Society guidelines emphasize a possible effect of LRS in Stage IV SINETs with unresectable liver metastases. On the contrary, the 2017 National Comprehensive Cancer Network Guidelines on carcinoid tumors do not support the resection of a small, asymptomatic, relatively stable primary tumor in the presence of unresectable metastatic disease. Furthermore, a recent study revealed no survival advantage for asymptomatic patients with distant-stage disease who underwent upfront LRS. At the aforementioned paper, it was suggested that delayed surgery as needed was comparable with the upfront surgical approach in terms of postoperative morbidity and mortality, the length of the hospital stay and the rate of incisional hernia repairs but was associated with fewer reoperations for bowel obstruction. On the other hand, it is also important to note that some patients might benefit from a prophylactic surgical approach and our attention should focus on identifying this patient population.
