The purpose of this study was to investigate the current status of postpartum depression intervention program performed in Korea and to evaluate its effectiveness. Of the Korean academic journals reported until November 2018, 13 experimental studies were selected and used for final analysis. The average age of the subjects was 26.9 to 34.4 years, and subjects were puerperal women or couples. The sample size was 6~39 (mean: 20.4) in the experimental group, 5~40 in the control group (mean: 20.0), and the intervention program consisted of 0.5~12 weeks/2~14 sessions/10~120 minutes per session. The design of all the studies was a non-equivalent control group pre-post test design. The main dependent variables, postpartum depression, fatigue, and maternal role self-confidence, were all found to have a statistically significant median level of effect size in the meta-analysis. This study confirms the composition and effects of various experimental studies used to mediate postpartum depression in Korea. This could be used as specific evidence-based data to form an optimal postpartum intervention program.

Two young women were brought to the Emergency room with generalized tonic and clonic seizures. Seizure developed seven and ten days after delivery respectively without the clinical signs of pre-eclampsia throughout the pregnancies. Magnetic resonance(MR) image of the brain showed characteristically symmetrical abnormal signals in the parietal and occipital regions. After several days of medical treatment, they were discharged without neurologic sequelae and follow-up MR images taken three months after discharge showed complete disappearance of the previous abnormal signals.

Objective: Pregnant Nelore heifers (n = 417) were used to evaluate the effects of supplementation with monensin-molasses multinutrient block (B) during pre and/or postpartum on reproductive and progeny performance. Methods: Heifers were allocated in four treatments: i) CC: heifers received control supplement (C) in loose meal form (0.06% of body weight [BW] offered daily before and after parturition; n = 108); ii) CB: received C before parturition and B (0.07% of BW offered weekly after parturition; n = 117); iii) BC: received B before and C after parturition (n = 103) and iv) BB: received B before and after parturition (n = 89). During pre and postpartum periods, concentration of metabolites/hormones and cow/calf performance was evaluated over time. Cows were synchronized twice for fixed timed artificial insemination (FTAI) using an estradiol/progesterone-based protocol. Data was analyzed by orthogonal contrasts (C). Results: B increased pregnancy at first FTAI (p = 0.04) and overall pregnancy rate (C1: CC vs BB+BC+CB; p = 0.05). Supplemented cows had greater body condition score (BCS) only at parturition (D0; p = 0.04) and at D40 (p = 0.02). B increased BW (p = 0.03), glucose concentrations (p = 0.01) and subcutaneous fat thickness (p = 0.03) only at D40. Concentrations of insulin were higher in supplemented cows (p = 0.008). Calves born by cows supplemented before and after parturition (C2: BB vs BC+CB) were heavier at 80 (p<0.001), 120 (p<0.001), 170 (p = 0.002) and 210 (p = 0.02) days old. Conclusion: Regardless of period of treatment, block supplementation increased pregnancy at first FTAI and overall pregnancy rate. Additionality, block supplementation during both pre and postpartum periods improved progeny weight until weaning. Block supplementation can be a tool to optimize fertility and calf performance in Nelore primiparous cows.

We investigated the effect of reproductive herd health program (RHHP) on the reproductive performance in high yielding dairy herds. Data collected from 205 lactations at Boeun County, Chungbuk from April 2001 to Dec. 2003 included postpartum reproductive and metabolic diseases, body condition score (BCS), reproductive performance and milking records. First we compared the reproductive performance of cows without RHHP (pre-RHHP group) and cows with RHHP (RHHP group). Intervals from calving to first service (99.6 vs. 81.8 days) and to conception (160.3 vs. 131.8 days) were shorter in the RHHP group than in the pre-RHHP group. Secondly, we determined the effect of milk yield (305 days) on the occurrence of postpartum diseases, BCS changes, and reproductive performance in cows under RHHP. The occurrence of metritis and metabolic diseases were greater in the over-10,000 kg group than in the under-10,000 kg group. The over-10,000 kg group lost more body condition than the under-10,000 kg group from calving to month 3 postpartum. Nevertheless, reproductive performance did not differ between the two groups. These results indicate that reproductive performance can be improved by the application of RHHP in high yielding dairy herds and that reproductive performance in the cows under RHHP are not affected by high milk yielding.

Purpose: This study was to develop a breastfeeding promotion program and to test effects of the program on levels of breast discomfort, breast size, sodium in breast milk, and type of feeding in mothers with breast engorgement following cesarean birth. Methods: A non-synchronized non-equivalent control group pretest-posttest design was used in this study. The participants were 70 postpartum mothers who were admitted to a postpartum care center and experienced breast engorgement following cesarean birth. The planned nursing intervention was the breastfeeding promotion program consisting of breast massage and 1:1 breastfeeding education, counseling, and support focusing on individualized problem solving provided for 10 days. Fifty-three women completed the program (experimental group 26, control group, 27). Measurements were level of breast discomfort, breast size, sodium in breast milk and type of feeding at pre and posttest. Results: Women who participated in the program experienced lower scores for breast discomfort, greater decrease in breast size, lower levels of sodium in breast milk, and practiced breastfeeding more than those in the control group. Conclusion: Results indicate that this breastfeeding promotion program is effective in reducing breast engorgement and improving breastfeeding practices, and is therefore recommended to enhance breastfeeding promotion practice in postpartum care centers.

The reproductive tracts have an intimate relationship with reproduction because there are bacterial communities that can affect reproductive health. The differences in the bacterial community of periparturient dairy cows were investigated. Vaginal and fecal samples were collected seven days before and after calving, and DNA was extracted to sequence the V3-V4 regions of the 16S rRNA genes. In the postpartum vaginas, operational taxonomic units, Chao1, Shannon, and Simpson were decreased, and phyla Fusobacteria and Bacteroidetes were increased. In summary, bacterial abundance can affect the periparturient biological differences in dairy cows, suggesting a susceptibility to infection within one week after calving.

The effect of supplementary feeding on postpartum ovarian activity, reproductive performance and plasma progesterone concentrations in Cheju native cows was studies. The group with adequate nutrition had greater mean body weight than did the underfed group before and after calving. First ovulation occurred 19.5 days and first oestrus at 37.8 days postpartum in the standard group, however, there was delay in first ovulation and oestrus in the restricted group (73.4 days and 111.8 days). Progesterone concentraitons of full fed animals gradually increased from 6 weeks(0.5ng/ml) to 12 weeks(3.3ng/ml) after calving. However, progesterone concentrations of underfed animals had a slight increase in 10 weeks after dalving(0.80ng/ml).

The present study investigated the developmental pattern of Korean mothers' depressive symptoms from a week prior to birth through four months postpartum in a nationally represented survey sample in Korea, using a Latent Growth Curve model. Mother-reported four factors-maternal self-efficacy in parenting, father's participation in childcare, a number of hours mothers worked per week, child's emotional temperament-were examined as the predictors of depressive symptoms over time in the context of Korean culture. Effects of maternal depressive trajectories on their infants' developmental outcomes at the first year were also examined. Findings were as follows: First, mothers' reports of depressive symptoms decreased at the first month after birth and then increased again during the first 4 months postpartum. Second, mothers' perceived low spousal involvement in childcare, low parental self-efficacy, and their infants' difficult temperament at four-month old had significantly positive relations to the initial level of maternal depressive symptoms whereas the low spousal involvement in childcare and low maternal self-efficacy factors significantly predicted the changes of trajectories of maternal depressive symptoms. Third, the trajectories, in turn, predicted warm and responsive maternal parenting style at the fourth month. Subsequently, the parenting style had a significant longitudinal impact on the development of children's communication, problem-solving, and personal-social abilities. Based on these findings, awareness, preventive and interventional programs might be built to facilitate Korean mothers suffering severe postpartum depressive symptoms and further promote optimal early development of Korean children.

Purpose: This study was conducted to examine the effects of simulation-based practice using standardized patients for the care of woman with postpartum hemorrhage as related to clinical performance competence and critical thinking deposition of nursing students. Methods: A nonequivalent control group pre-post test experimental design was used. Fifty four third year students were recruited, 29 students for the experimental group and 25 students for the control group. The simulation-based practice about nursing care related to postpartum hemorrhage included skill training, team-based practice, and debriefing. It was implemented with the experimental group for about 30 minutes in October 6, 2011. Data were analyzed using frequency, ratio, chi-square, Fisher's exact probability, and t-test using the SPSS/WIN program. Results: The experimental group who had the simulation-based practice showed significantly higher knowledge and skills of clinical performance competence than the control group (t=2.19, p=.003). But the experimental group who had the simulation-based practice did not show significantly higher critical thinking deposition than the control group (t=-0.32, p=.748). Conclusion: The results indicate that a simulation-based practice is an effective teaching method to improve knowledge and skills for clinical performance competence of nursing students. Further study is needed to identify the effect of a simulation-based practice on nursing attitudes.

Purpose: The purposes of this study were to develop a postpartum nursing intervention program for immigrant women and evaluate the effects on postpartum depression, child rearing confidence, home environment, and infant temperament. Methods: This research was a non-equivalent control group pre-test and post-test design. Participants were pregnant immigrant women from China, Vietnam, and the Philippines residing in Kyunggi province and Seoul. Twenty women were assigned to the intervention group, and 19 women to the control group. For the intervention group, the women were visited at home and provided emotional support and parenting education for three months. To analyze the intervention effects, repeated measure ANOVA and t-test were used. Results: Child rearing confidence was higher in the experimental group than the control group at interaction effect of time and group, six weeks and three months postpartum. However, there were no significant effects for maternal depression, infant temperament, and husband support. Home Observation for Measurement of the Environment (HOME) score in the experimental group was higher than that of the control group at three month postpartum. Conclusion: Results indicate that the nursing intervention program had positive effects and can be used to further the health status of immigrant mothers and children.
