ABSTRACT
Purpose@#Funisitis, inflammation of the umbilical cord, is considered a strong risk factor for adverse neonatal outcomes; however, a clinical definition of funisitis has not been established. In this study, we aimed to determine the clinical significance of funisitis in twin neonates with spontaneous preterm birth. @*Materials and Methods@#The study included preterm twin neonates (<35 weeks) delivered after spontaneous preterm labor and/ or preterm premature rupture of amniotic membranes. The presence of funisitis was examined in the umbilical cord of each twin.We analyzed the risk of adverse neonatal outcomes according to the presence and absence of funisitis. Adverse neonatal outcomes were defined as the occurrence of neonatal mortality, significant morbidity, or both. @*Results@#Among 474 preterm neonates (237 twin pairs) included in this study, the frequency of funisitis was 6.5% (31 cases). Funisitis was significantly associated with neonatal mortality and adverse neonatal outcomes after adjustment for confounding variables [neonatal mortality, odds ratio (OR) 9.043, 95% confidence interval (CI) 2.620–31.204; adverse neonatal outcome, OR 2.445, 95% CI 1.017–5.875]. The concordance rate of funisitis between the twins was 10.7%, and in the absence of funisitis in one twin, the risk of neonatal mortality or adverse neonatal outcome was not influenced by the presence of funisitis in the other twin. @*Conclusion@#The presence of funisitis appears to be associated with an increased risk for adverse neonatal outcomes in twin neonates with spontaneous preterm birth.
ABSTRACT
Objective@#This study aimed to investigate sperm motility and its changes after preparation as predictors of pregnancy in intrauterine insemination (IUI) cycles. @*Methods@#In total, 297 IUI cycles from January 2012 to December 2017 at a single tertiary hospital were retrospectively analyzed. Patient and cycle characteristics, and sperm motility characteristics before and after processing were compared according to clinical pregnancy or live birth as outcomes. @*Results@#The overall clinical pregnancy rate per cycle was 14.5% (43/297) and the live birth rate was 10.4% (30/289). Patient and cycle characteristics were similar between pregnant and non-pregnant groups. Sperm motility after preparation and the total motile sperm count before and after processing were comparable in terms of pregnancy outcomes. Pre-preparation sperm motility was significantly higher in groups with clinical pregnancy and live birth than in cycles not resulting in pregnancy (71.4%±10.9% vs. 67.2%±11.7%, p=0.020 and 71.6%±12.6% vs. 67.3%±11.7%, p=0.030, respectively). The change in sperm motility after processing was significantly fewer in the non-pregnant cycles, both when the comparison was conducted by subtraction (post-pre) and division (post/pre). These relationships remained significant after adjusting for the female partner’s age, anti-Müllerian hormone level, and number of pre-ovulatory follicles. According to a receiver operating characteristic curve analysis, an initial sperm motility of ≥72.5% was the optimal threshold value for predicting live birth after IUI. @*Conclusions@#Initial sperm motility, rather than the motility of processed sperm or the degree of change after preparation, predicted live birth after IUI procedures.

ABSTRACT
This study assesses the fertilization and blastocyst-forming rate in mice cumulus-oocyte complexes (COCs) after the exposure of human ovarian endometriotic fluid. Endometriotic fluid was obtained from a single patient by aspiration at the time of a laparoscopic cystectomy and serially diluted. COCs were obtained from 46-week-old female BDF1 mice. After exposure to ovarian endometriotic fluid for five minutes, the COCs were washed three times and the oocytes were then fertilized by mice sperm. The fertilization and blastocyst formation rate and the proportion of hatching/hatched blastocyst in the four treatment groups were not inferior to those in non-exposure group.

OBJECTIVE: Mid-sized hospital websites were assessed to examine how their attributes influence outcome indicators as a potential marketing strategy. Specifically, the website attributes considered were accessibility, content sufficiency, and layout design, while outcome indicators were evaluated, based on satisfaction with the website, intention to revisit the website, and intention to recommend the hospital. METHODS: Five representative websites were selected according to their ranks derived from major ranking sites. The diversity of the websites were emphasized. Then, a questionnaire survey was conducted on 74 respondents. Collected data was analyzed, using frequency, correlation, and repeated measures analysis of variance. RESULTS: All three attributes were related to satisfaction with the website; in addition, both content sufficiency and layout design were significantly related to the intention to revisit. As for the intention to recommend the hospital, only the content sufficiency was significant. In particular, the sufficiencies on 'disease or symptoms' and 'question and answer' were important to all three outcome indicators. CONCLUSION: The websites serve as a marketing tool in managing mid-sized hospitals. Well-designed websites containing sufficient contents facilitate visitor's satisfaction and intention to revisit the website, as well as furthering their intention to recommend the hospital.
