METHODS Endometrial biopsies from 135 women with recurrent miscarriage were obtained precisely 7 days after luteinizing hormone surge in natural cycles. Endometrial sections were immunostained for CD56 for uNK cells and CD138 for plasma cells, respectively. Uterine NK cell counting was performed according to a standardized protocol and results were expressed as percentage of CD56+ cells/ total stromal cells. High uNK cell density was defined as >4.5% and CE was diagnosed when the plasma cell density > 5.15 cells/ 10 mm2 . RESULTS The uNK cells density in women with CE (median, 5.1%; range, 3.4-8.8%) was significantly (P  less then  0.05) higher than that of those without CE (median, 3.8%; range, 1.2%-7.3%). The prevalence of high uNK cell density in women with CE (11/29, 37.9%) was significantly (P  less then  0.05) higher than that of women without CE (8/106, 7.5%). CONCLUSION To conclude, there was a significant association between high uNK cell density and CE. In women with high uNK cell density, plasma cell should be examined to determine if the underlying cause is associated with CE. © 2020 Japan Society of Obstetrics and Gynecology.AIMS To examine the pertinent issues discussed by endometriosis patients in Malaysia on MyEndosis Facebook group as an alternative platform for online support. METHODS Using thematic analysis based on three frameworks, 120 posted messages and comments were examined from MyEndosis Facebook group-a support group for women with endometriosis from January to July 2014. RESULTS Results showed the issues discussed were (a) personal struggles, (b) medication and treatment, (c) alternative medication, (d) side effects, and (e) medication recommended by doctors. While using this social medium, users found (a) emotional support, (b) esteem support, (c)
