Self-assessment sheet submission rate predicts technique survival in patients initiating peritoneal dialysis.

AIM: Patients play a crucial role in preventing peritoneal dialysis (PD)-related events, including peritonitis and fluid overload, as PD procedures are mainly carried out at home. We asked patients to submit a PD self-assessment sheet at each outpatient visit in our daily clinical practice and evaluated its usefulness for outcomes in patients initiating PD. METHODS: This retrospective cohort study included patients who underwent PD catheter insertion between January 2008 and October 2018. The submission rate of a PD self-assessment sheet was calculated from medical records until PD cessation or study completion (October 2020). The association between the submission rate and technique survival was analysed. RESULTS: Among the 105 recruited patients (78 men, 60.4 ± 12.2 years), 44 discontinued PD and transferred to haemodialysis during the study period. The follow-up was 52.3 (28.7-79.3) months, and the median submission rate was 78%. The log-rank test showed that technique survival was significantly better in patients with a submission rate ≥ 78% than those with a submission rate <78% (p = .006). The submission rate remained significantly associated with less technique failure (hazard ratio 0.88 per 10%, p = .002) by the Cox regression analysis adjusted for age, sex, Charlson comorbidity index, estimated glomerular filtration rate and geriatric nutritional risk index. CONCLUSION: The submission rate of a PD self-assessment sheet is useful as a predictor of technique survival in patients initiating PD. Instruction that increases submission may improve technique survival in PD patients.

Optimal gestational weight gain for underweight pregnant women in Japan.

We aimed to investigate the optimal range of gestational weight gain (GWG) for Japanese underweight (body mass index <18.5 kg/m2) women using the Japanese Birth Registry System. The study subjects included underweight women who were divided into groups according to the GWG recommendations of the Ministry of Health, Labour and Welfare (MHLW) (9-12 kg): <9.0 kg, group A; 9-12 kg, group B; and >12 kg, group C. The subjects were then classified according to the recommendations of the Institute of Medicine (IOM) (12.7-18.1 kg): <12.7 kg, group D; 12.7-18.1 kg, group E; and >18.1 kg, group F. In total, 148,135 cases were analysed. The frequencies of small for gestational age, preterm delivery, and caesarean delivery were as follows: 19.3%, 22.7%, and 28.5% for group A; 11.7%, 8.7%, and 22.8% for group B; 8.0%, 4.9%, and 21.5% for group C; 15.0%, 14.7%, and 25.2% for group D; 8.0%, 5.3%, and 21.5% for group E; and 7.0%, 5.5%, and 25.0% for group F, respectively. These results indicated that groups C and E had the best outcomes. Therefore, the IOM guidelines seem more appropriate than the MHLW guidelines. Therefore, the MHLW recommended GWG guidelines require revision.

Adverse pregnancy outcomes related to preterm cesarean delivery.

OBJECTIVE: Cesarean delivery at a preterm gestational age has been related to maternal complications such as bleeding and infection. However, previous reports are conflicting, and there is no consensus on the matter. We aimed to clarify the adverse effect of preterm cesarean delivery with an emphasis on maternal bleeding. STUDY DESIGN: We conducted a retrospective study comparing the frequency of maternal adverse outcome between preterm emergency cesarean delivery and term emergency cesarean delivery. Nine hundred and forty seven preterm cases and 1056 full-term cases were included in the study. We analyzed the frequency of abnormal bleeding defined as 1500 mL or more as primary outcome, blood transfusion rate, and rate of postoperative administration of antibiotics as secondary outcome. Logistic regression analysis was performed for confounding variables; age at delivery, primiparity, obesity, prior history of uterine surgery, abnormal placental position, abnormal glucose tolerance, hypertension during pregnancy, early rupture of membranes, and general anesthesia use during operation. As secondary analysis, to study the effects of method of incision, we compared adverse outcomes among classical cesarean delivery, inverted T incision, and upper segment incision within preterm emergency cesarean delivery. RESULTS: Preterm cesarean delivery had significantly higher rates of abnormal bleeding, transfusion and use of antibiotics than term cesarean delivery. Among the preterm delivery, classical incision was related to increased rate of blood transfusion and need for antibiotic treatment. CONCLUSION: Preterm cesarean delivery increases the risk of maternal bleeding. This should be considered especially in the setting of early preterm birth.

Hygroscopic dilators vs balloon catheter ripening of the cervix for induction of labor in nulliparous women at term: Retrospective study.

OBJECTIVE: To compare the efficacy and safety of hygroscopic dilators and balloon catheters for ripening of the cervix in induction of labor. STUDY DESIGN: This retrospective, observational study used data from the Successive Pregnancy Birth Registry System of the Japan Society of Obstetrics and Gynecology from 2012 to 2014. Nulliparous women in whom labor was induced by mechanical methods of cervical ripening at term were enrolled. The eligible women were divided into dilator, balloon <40 mL, balloon ≧40 mL, and overlapping groups. RESULTS: The groups included 4645, 4100, 6615, and 1992 women, respectively. In the overlapping group, which included the women in whom delivery was most difficult, the vaginal delivery rate was lower and the intrauterine infection and neonatal mortality rates were higher than those in the dilator group. No difference in the vaginal delivery rate was observed among the dilator, balloon <40 mL, and balloon ≧40 mL groups (74.6%, 72.3%, and 73.8%, respectively; p>0.05). The vaginal instrumental delivery rate was higher in the two-balloon groups than in the dilator group. The volume of intrapartum hemorrhage was lowest in the dilator group. No significant difference in the frequencies of uterine rupture and intrauterine infection were observed among the dilator and two-balloon groups. With regard to neonatal outcomes, the frequency of a low Apgar score was statistically significantly lower in the dilator group than in the two-balloon groups. Moreover, the frequency of neonatal death tended to be lower in the dilator group than in the two-balloon groups. CONCLUSION: With regard to cervical ripening for labor induction in nulliparous women at term, the vaginal delivery rate on using a dilator and on using a balloon seems to be equivalent. Concerning maternal complications and neonatal outcomes, cervical ripening with hygroscopic dilators in labor induction might be safer.

Systemic lupus erythematosus: strategies to improve pregnancy outcomes.

Systemic lupus erythematosus (SLE) is a chronic autoimmune inflammatory disease with a high prevalence in females of childbearing age. Thus, reproduction in SLE patients is a major concern for clinicians. In the past, SLE patients were advised to defer pregnancy because of poor pregnancy outcomes and fear of SLE flares during pregnancy. Investigations to date show that maternal and fetal risks are higher in females with SLE than in the general population. However, with appropriate management of the disease, sufferers may have a relatively uncomplicated pregnancy course. Factors such as appropriate preconception counseling and medication adjustment, strict disease control prior to pregnancy, intensive surveillance during and after pregnancy by both the obstetrician and rheumatologist, and appropriate interventions when necessary play a key role. This review describes the strategies to improve pregnancy outcomes in SLE patients at different time points in the reproduction cycle (preconception, during pregnancy, and postpartum period) and also details the neonatal concerns.

Relationship Between Short Umbilical Cord Length and Adverse Pregnancy Outcomes.

To investigate how umbilical cord length relates to pregnancy outcomes, we retrospectively analyzed data from 89,042 deliveries recorded in the Japan Society of Obstetrics and Gynecology Successive Pregnancy Birth Registry System. We included term deliveries in which vaginal birth was attempted. Umbilical cord length was categorized into four groups: less than the first percentile, from the first percentile to less than the 10th percentile, from the 10th percentile to less than 25th percentile, and from the 25th percentile to less than the 75th percentile, which constituted the control group. Cord lengths of 33, 43, 48, 63 cm corresponded to the first, 10th, 25th, and 75th percentile values of the cord length distribution, respectively. Statistically significant differences were observed in the rate of unplanned cesarean delivery for all three short cord groups compared to control. There was a higher odds ratio for unplanned cesarean delivery as the umbilical cord became shorter.

Pregnancy outcomes of women with coexisting systemic lupus erythematosus flare and preeclampsia.

OBJECTIVES: Systemic lupus erythematosus (SLE) flare and preeclampsia are difficult to differentiate from each other and occasionally coexist; This study aimed to analyze cases requiring termination of pregnancy due to SLE flare or preeclampsia and to elucidate the association between these two conditions; Methods. Out of 71 pregnancies in 60 women managed for SLE-complicated pregnancies who delivered at or after 22 weeks' gestation at a tertiary center, 7 pregnancies were terminated due to uncontrollable severe SLE flare or severe preeclampsia We retrospectively analyzed the clinical courses and laboratory findings of these 7 cases to determine whether their pathological conditions were attributable to SLE flare alone, preeclampsia alone, or the coexistence of these two conditions. RESULTS: One of the 7 cases had preeclampsia alone, two had SLE alone, and four had both conditions. The coexistence of preeclampsia and SLE was thus the most common condition. In cases with both conditions, SLE flare had preceded preeclampsia, thereby making treatment after delivery difficult. CONCLUSION: Severe SLE flare often preceded severe preeclampsia and worsened after delivery. When differentiating severe SLE flare from severe preeclampsia is difficult during pregnancy, women should be regarded as having SLE flare rather than preeclampsia and aggressively treated.
