Seventy-two patients initiated intrauterine insemination between March 1989 and March 1990. Indication for the intrauterine insemination included abnormal semen, poor cervical mucus, presents of sperm antibody, unexplained, poor postcoital test and endometriosis. During this time period, 216 inseminations were performed and resulted in twenty four pregnancies in the 72 patients receiving artificial insemination by homologous donor for an overall pregnancy rate of 33.3%. Where pergonal treatment was followed by insemination, a significantly greater pregnancy per cycle was achieved. It is therefore suggested that a trial if induction of multiple follicular development be performed on coulpes with male-related or unexplained infertility before inclusion in protocols for invasive procedures, such as IVF or GIFT.

Purpose: This study was designed to explore the relationship of situational meaning with maternal self-esteem in mothers with high risk newborn. Method: The subjects of this study were 82 mothers with high risk newborn. Data were collected using a translated Family Meaning Attribution Scale and Maternal Self-Report Inventory. Data were analyzed using descriptive statistics, t-test, Pearson Correlation Coefficients and Stepwise Multiple Regression. Result: The average score of the situational meaning in high risk newborn mothers was 64.0l(possible score is between 0-96) and the average score of each item was 1.98. The average score of the maternal self-esteem in high risk newborn mothers was 81.96(possible score is between 26-104) and the average score of each item was 3.15. No significant differences were found in situational meaning according to general characteristics except whether it was a planned pregnancy or not. No significant differences were found in maternal self-esteem according to general characteristics except disease or admission experience during pregnancy. There was significant positive correlation between situational meaning and maternal self-esteem. Conclusion: It is necessary for nurses to provide high risk newborn mothers with care for improving situational meaning that is attributed to the mothers. It can be helpful to improve maternal self-esteem and in the end it will facilitate the maternal transition in mothers with high risk newborn.

Here, we report isolation of multiple long non-coding RNAs (lncRNAs) expressed tissue-specifically during murine embryogenesis. One of these, subsequently came to be known as Redrum, is expressed in erythropoietic cells in fetal liver and adult bone marrow. Redrum transcription is also detected during pregnancy in the spleen where extramedullary hematopoiesis takes place. In order to examine the function of Redrum in vivo, we generated a gene-targeted murine model and analyzed its embryonic and adult erythropoiesis. The homozygous mutant embryo showed no apparent deficiency or defect in erythropoiesis. Adult erythropoiesis in bone marrow and in the spleen during pregnancy likewise showed no detectable phenotype as red blood cells matured in normal fashion. The phenotype is in contrast to the reported function of Redrum in vitro, and our observation implies that Redrum plays in vivo an accessory or supplementary role whose loss is compatible with normal erythropoiesis.

Objectives: Stillbirth is a common adverse pregnancy outcome that represents a distressing and traumatic event for women and their partners. The aim of this study was to identify factors associated with stillbirth in ever-pregnant women in Nepal. Methods: This study utilized the individual women's dataset from the Nepal Demographic and Health Survey, conducted in 2016. The dependent variable of interest was whether women had at least 1 stillbirth during their lifetime. The associations between independent variables and the dependent variable of the study were analyzed using a multiple logistic regression model. Results: Among 8918 ever-pregnant women aged 15-49 years, 488 had experienced at least 1 stillbirth during their lifetime, representing 5.5% of the total. After adjusting each factor for the confounding effects of other factors, maternal age, maternal education, place of residence, and sub-region remained significantly associated with having experienced stillbirth. Conclusions: Stillbirth continues to be a major problem among women, especially those with higher maternal age, those who are illiterate, and residents of certain geographical regions. To minimize stillbirth in Nepal, plans and policies should be focused on women with low education levels and residents of rural areas, especially in the western mountain and far-western hill regions.

Purpose: This study aimed to identify factors associated with diabetes management self-efficacy in pregnant women with gestational diabetes mellitus (GDM) in Korea. Methods: A total of 173 pregnant women with GDM in Korea were recruited by posting announcements at two Korean online communities focusing on pregnancy and GDM. Participants completed a structured online survey from July to September 2018. Thirteen inappropriate responses were excluded and a total of 160 questionnaires were used in the final analysis. Descriptive statistics were calculated and multiple regression with the enter method was done to identify the associations of depressive mood, anxiety, emotional intelligence, and sleep quality with diabetes management self-efficacy. Results: Respondents reported a moderately depressive mood (mean, 10.36), low to moderate anxiety (mean, 41.65), above-average emotional intelligence (mean, 78.04), moderate sleep quality (mean, 42.01), and above-average diabetes management self-efficacy (mean, 52.29). The major factor associated with diabetes management self-efficacy of pregnant women with GDM was emotional intelligence (β=.51, p<.001). Other factors, in descending order of influence, were sleep quality (β=.22, p<.001) and exercise (β=.18, p=.004). Taken together, the aforementioned factors explained 34.6% (F=39.53, p<.001) of the total variance. Conclusion: The results of this study suggest that to improve the diabetes management self-efficacy of pregnant women with GDM, it is necessary to develop an education program that can also enhance emotional intelligence, sleep quality, and exercise.

Purpose: The aim of this study was to investigate the educational status and needs of premature birth prevention, and to identify factors associated with preconception health behaviors. Methods: The study design was a crosssectional descriptive study. Data were collected through an online questionnaire survey, and the subjects were 192 women of childbearing age in Korea. Data were analyzed using the Mann-Whitney U test, Kruskal-Wallis test, Spearman's correlation coefficients, and multiple regression. Results: The proportion of subjects who received education on premature birth prevention was 8.9%, and 75.5% of subjects answered that they needed education on premature birth prevention. They demanded education through online media, small groups, cases, cartoons (webtoon) with stories, pictures, and videos. A related factor of preconception health behavior was self-efficacy for high-risk pregnancy health care (β=.20, p=.012), which accounted for 8.2% of the total variance related to preconception health behavior. Conclusion: There was a need for more development of education programs to prevent premature birth for women of childbearing age. Its education programs should be applied with online, small group activities using various educational media. It is also required to promote preconception health behavior through self-efficacy for high-risk pregnancy health care.

목적: 시험관아기 시술에서 3일째의 배아들 가운데 우수한 배아를 선발하여 1개의 배아를 이식 (elective single embryo transfer, eSET)한 주기와 2개의 배아를 이식 (elective double embryo transfer, eDET)한 주기의 임상적 결과들을 비교, 분석하고자 하였다. 연구방법: 본 연구는 2008년 1월부터 2009년 4월까지 대구마리아에서 첫 번째나 두 번째 In vitro fertilization-embryo transfer (IVF-ET)를 시행한 36세 미만인 환자들 가운데 hCG를 투여한 당일 자궁내막의 두께가 8 mm 이상이고 정상적인 수정란이 3개 이상이면서 적어도 1개의 우수한 배아를 지닌 환자들을 대상으로 실시하였다. eSET는 167주기에서 실시하였고 eDET는 163주기에서 실시하였다. 결과: eSET군의 임상적 임신율, 진행 임신율 및 출산율 (각각 53.3%, 47.3% 및 44.9%)은 eDET군의 것들 (각각 60.7%, 54.6% 및 50.9%)보다 통계적으로 유의한 차이가 없었다. 그러나 착상률은 eSET군이 eDET군보다 통계적으로 유의하게 높았고 (각각 53.9%와 40.2%, p<0.001), 쌍태아의 임신율은 eSET군이 eDET군보다 유의하게 낮게 나타났다 (각각 1.1%와 32.3%, p<0.001). 또한, 잉여배아들을 유리화하여 보관하게 된 환자의 비율은 eDET군보다 eSET군에서 유의하게 높았을 뿐만 아니라 (각각 68.7%와 89.2%, p<0.001), 환자당 보관된 잉여배아의 수도 eSET군에서 eDET군에 비하여 유의하게 높게 나타났다 (각각 $3.2{\pm}2.6$과 $2.1{\pm}2.4$,p<0.001).결론: 채취당 임신율을 높이고 다태아의 임신에서 기인한 합병증 등을 줄이기 위해서는 내원한 첫 번째나 두 번째 IVF-ET 환자들 가운데 36세 미만이고 HCG를 투여한 당일 자궁내막의 두께가 8 mm이상이며 3일째에 우수한 배아가 하나만 있더라도 eDET보다 eSET를 실시함이 바람직하다고 생각된다.

Because multiple ovulation embryo transfer (MOET) in cattle includes several benefits such as wide spreading of genetically superior offspring for long distance, this biotechnological method has been widely applied to Hanwoo. When the recipients are not stayed close after embryo recovery from donor, the embryos are moved to other farms via several vehicles (car, train, and airplane). However, air travel induces lesser oxygen level, increased vibration, lower air pressure, higher noise, and increased exposure of cosmic radiation to living things than ground level. It was still unknown that fresh embryos obtained from multiple ovulation of Hanwoo could maintain their fertility after being transported via air plane, the present case report introduced a clinical case of MOET in Hanwoo after shipping fresh embryos via air transportation. The donor was multi-ovulated via follicle-stimulating hormone series of injection, which was followed by a gonadotrophin-releasing hormone injection and artificial insemination twice. The embryos were recovered by the uterine flushing, packed in ministraws, transported to recipients for 6 h including 1 h air flight, and then transferred to the synchronized recipients. During pregnancy diagnosis of early gestation period, 5 of 7 recipients (71.4%) presented no heat signs and showed fetal sacs with fluid under transrectal ultrasonography. After normal gestation period, all recipients naturally delivered healthy calves (male n = 2 and female n = 3) without abortion, stillbirth, and premature birth. The present case report indicated that transportation of fresh embryos for MOET via domestic flight in Korea did not affect to their fertility.

Positional plagiocephaly is increasing in infants. Positional plagiocephaly is an asymmetric deformation of skull due to various reasons; first birth, assisted labor, multiple pregnancy, prematurity, congenital muscular torticollis and position of head. Positional plagiocephaly can mostly be diagnosed clinically and by physical examinations. The simplest way to assess the severity of plagiocephaly is to use a diagonal caliper during physical examination, which measures the difference between the diagonal lengths on each side of the head. Plagiocephaly can be treated surgically or conservatively. Positional plagiocephaly, which is not accompanied by craniosynostosis, is treated conservatively. Conservative treatments involve a variety of treatments, such as change of positions, physiotherapy, massage therapy, and helmet therapy. Systematic approaches to clinical examination, diagnosis and treatment of positional plagiocephaly can be necessary and the age-appropriate treatment is recommended for patients with positional plagiocephaly.
