OBJECTIVE:
Coronavirus disease 2019 (COVID-19) can result in fatigue and post-exertional malaise; however, whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection exacerbates lower urinary tract symptoms (LUTS) is unclear. This study investigated the association between prenatal SARS-CoV-2 infection and postpartum LUTS.
METHODS:
A multicenter, retrospective cohort study was conducted at two tertiary hospitals in China from November 1, 2022, to November 1, 2023. Participants were classified into infected and uninfected groups based on SARS-CoV-2 antigen results. LUTS prevalence and severity were assessed using self-reported symptoms and the Incontinence Impact Questionnaire-Short Form (IIQ-7). Pelvic floor muscle activity was measured using electromyography following the Glazer protocol. Group comparisons were performed to evaluate the association of SARS-CoV-2 infection with LUTS and electromyography parameters, with stratified analyses conducted using SPSS version 26.0.
RESULTS:
Among 3,652 participants (681 infected, 2,971 uninfected), no significant differences in LUTS prevalence or IIQ-7 scores were observed. However, SARS-CoV-2 infection was an independent factor influencing the electromyographic activity of the pelvic floor muscles (mean tonic contraction amplitudes), regardless of delivery mode ( P = 0.001).
CONCLUSION
Prenatal SARS-CoV-2 infection was not significantly associated with an increased risk of postpartum LUTS but independently altered pelvic floor muscle electromyographic activity, suggesting potential neuromuscular effects.

Postpartum depression(PPD) is a common emotional disorder in the puerperium, which has negative impact on women, infants and family. There is growing evidence that abnormal concentration of a number of nutrients (including polyunsaturated fatty acids, vitamin D and homocysteine) is associated with depression in postpartum population. Further studies on the mechanisms for the functions of nutrients and regulation of nutritional states in the puerperium will be of great value in the prevention, early diagnosis and treatment of PPD.

3.Development and Evaluation of Breastfeeding Promotion Program for Mothers with Breast Engorgement following Cesarean Birth.
Journal of Korean Academy of Nursing 2014;44(2):170-178
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.

This retrospective study was conducted to confirm the relationship between pre- and postpartum metabolic parameters and postpartum reproductive performance and to clarify seasonal characteristics of the metabolic parameters by using our metabolic profile test (MPT) database of Japanese Black breeding herds. In evaluation 1, MPT databases of blood samples from multiparous cows collected prepartum and postpartum were divided into two groups according to calving interval, and each MPT parameter was compared. In evaluation 2, the same MPT databases used in evaluation 1 were divided into two groups according to the sampling period. Significant differences were found in the prepartal total protein and postpartal gamma-glutamyltransferase in evaluation 1. In evaluation 2, significant differences were found in the prepartal and postpartal total protein, albumin/globulin ratio, and glucose. Clear seasonal differences in MPT results emphasized the usefulness of the MPT in breeding cattle herds fed home-pasture roughage and suggest that unsatisfactory reproductive performance during hot periods reflects inadequate nutritional content of the diet and possible reduced feed intake due to heat stress.

OBJECTIVETo observe the impacts of the acupoint catgut implantation on postpartum pain of uterine contraction with qi and blood deficiency.
METHODSOne hundred and ten primiparas of natural delivery differentiated as qi and blood deficiency pattern in TCM were selected as the subjects. They were randomized into an acupoint catgut implantation group (55 cases) and a routine nursing group (55 cases). In the acupoint catgut implantation group, the catgut was implanted in Zigong (EX-CA 1), Zusanli (ST 36), Sanyinjiao (SP 6), Pishu (BL 20) and Geshu (BL 17) in 6 h after delivery; additionally, the routine post-delivery nursing was adopted. In the routine nursing group, the routine post-delivery nursing was applied simply. Visual analogue scale (VAS) and the pain relief time of uterine contraction were compared in 24 h, 48 h, 72 h and 96 h after acupoint catgut implantation between the two groups.
RESULTSVAS Scores in 24 h, 48 h, 72 h and 96 h after acupoint catgut implantation in the acupoint catgut implantation group were lower apparently than those in the routine nursing group (3.31 +/- 0.39 vs 4.31 +/- 0.29, 1.86 +/- 0.29 vs 2.66 +/- 0.25, 0.89 +/- 0.21 vs 1.59 +/- 0.24, 0.35 +/- 0.10 vs 0.69 +/- 0.13, all P < 0.05). The pain relief was achieved in (72.06 +/- 6.83) h in the acupoint catgut implantation group and was (123.42 +/- 11.12) h in the routine nursing group. The pain relief in the acupoint catgut implantation group was achieved more quickly (P < 0.01).
CONCLUSIONThe intervention of acupoint catgut implantation in 6 h after natural delivery in primiparas prevents effectively postpartum pain of uterine contraction.

OBJECTIVETo investigate the prevalence and related factors of abnormal pelvic floor muscle strength and provide theoretical evidence for the prevention and treatment of pelvic floor dysfunction.
METHODSA total of 1008 migrant women in hospitals of Guangzhou and Foshan were screened for pelvic floor strength at 42 days postpartum from Oct, 2013 to July, 2014. EMG biofeedback equipment was employed to assess the strength of type I and II muscle fiber and a questionnaire was designed to record its related factors.
RESULTSThe incidence of abnormal type I and II muscle fiber strength was 49.21% and 49.60%, respectively. No statistical significance was observed in the abnormal rates among women with different ages or occupations. Compared with women who chose vaginal delivery, women with cesarean section had significantly reduced abnormal rates. A negative correlation was found between parity and type I and II muscle fiber strength.
CONCLUSIONThe delivery mode and parity are factors affecting pelvic floor muscle strength among migrant women in the Pearl River Delta, suggesting the necessity of health education and promotion of family planning policy.

PURPOSE: The aim of this study was to review the literature to determine whether intensive pelvic floor muscle training during pregnancy and after delivery could prevent urinary and fecal incontinence. METHODS: Randomized controlled trials (RCT) of low-risk obstetric populations who had done Kegel exercise during pregnancy and after delivery met the inclusion criteria. Articles published between 1966 and 2012 from periodicals indexed in Ovid Medline, Embase, Scopus, KoreaMed, NDSL and other databases were selected, using the following keywords: 'Kegel, pelvic floor exercise'. The Cochrane's Risk of Bias was applied to assess the internal validity of the RCT. Fourteen selected studies were analyzed by meta-analysis using RevMan 5.1. RESULTS: Fourteen RCTs with high methodological quality, involving 6,454 women were included. They indicated that Kegel exercise significantly reduced the development of urinary and fecal incontinence from pregnancy to postpartum. Also, there was low clinical heterogeneity. CONCLUSION: There is some evidence that for antenatal and postnatal women, Kegel exercise can prevent urinary and fecal incontinence. Therefore, a priority task is to develop standardized Kegel exercise programs for Korean pregnant and postpartum women and make efficient use of these programs.

OBJECTIVETo explore the efficacy of Tuina for postpartum lactation and work out a optimal protocol involved.
METHODSWith a randomized, controlled and clinical method, 84 primiparas were divided into a Tuina group and a control group. While patients in the control group received rooming-in conventional managements, those in the Tuina group were additionally treated with Tuina, including local manipulations on breasts combined with acupoint manipulations. The colostrum-time, lactation quantity and prolactin were observed to make the comparisons between two groups.
RESULTSThe scores of lactation quantity after 1th, 2nd, 3rd of the treatment were 1.660 +/- 0.785, 2.530 +/- 1.030, 2.880 +/- 1.171 in Tuina group and 1.270 +/- 0.533, 1.460 +/- 0.811, 1.500 +/- 0.583 in control group respectively, where there were significant differences in each time stage between two groups (all P < 0.001). The time of colostrum was (21.6 6 +/- 10.508) h in the Tuina group and (22.5 +/- 9.762) h in the control group, in which the difference was not statistically significant (P > 0.05). The levels of prolactin (314.35 +/- 110.37) ng/mL and (321.56 +/- 109.61) ng/mL in Tuina group, (385.78 +/- 85.19) ng/mL and (340.12 +/- 103.10) ng/mL in control group before and after treatment, there were no significant differences (both P > 0.05).
CONCLUSIONPostpartum Tuina on breasts could increase the quantity of lactation and delay the decreasing of the levels of prolactin, which contributes primiparas to lactate more and sooner.

10.Effect of auricular point sticking on lactation of puerperant.
Chinese Acupuncture & Moxibustion 2012;32(12):1087-1089
OBJECTIVETo explore an effective method for puerperant to lactate.
METHODSOne hundred and seven cases that were about to giving a birth in our hospital were randomly divided into an observation group (52 cases) and a control group (55 cases). Based on the routine hospital care, the patients in the observation group received auricular point sticking with vaccaria seed at Endocrine (CO18), Mammary Gland, etc. after 1 hour of childbirth, which was pressed 3 times daily, for 1-2 min each time. In the control group, routine hospital care was given, which didn't include auricular point sticking. The lactation volume, starting time of lactation and serum prolactin (PRL) were observed after 5 days of treatment.
RESULTSCompared with the control group, lactation volume in the observation group was more superior (P < 0.01). Rate I of lactation volume in the observation group was 51.9% (27/52), which was obviously higher than 27.3% (15/55) in the control group (P < 0 01). The starting time of lactation in the observation group was obviously earlier than that in the control group (P < 0 05). The content of PRL was apparently improved after one or two days of childbirth (both P < 0.05), and significantly increased after 5 days (P < 0.01).
CONCLUSIONThe auricular point sticking is a better method to promote lactation for puerperant, which could be beneficial to increasing the success rate of breastfeeding.
