OBJECTIVE

Preterm birth is a major cause of complications leading to death of children under 5 years old. Infections are important to be identified because antimicrobial treatment may prevent or delay progression to preterm delivery. This study determined if routine screening tests of infections are useful in the clinical management of preterm labor.

A cross-sectional (descriptive) study was done involving 417 pregnant patients who had preterm labor and was subsequently admitted from 2015 to 2019 at a tertiary hospital in the Philippines, using review of past medical records, inpatient charts, and admission charts.

Majority of the patients delivered at less than 34 weeks, most of the culture results turned out negative, and urine tests were more commonly employed as screening tests for preterm labor. The endocervical and rectovaginal swab studies had no significant growths. Asymptomatic bacteriuria was diagnosed in 1 out of 10 patients and they were subsequently started on antibiotic treatment. Majority of the patients who were given antibiotics delivered within 48 hours from admission. 

The routine use of cultures in the assessment of preterm labor is costly and is unlikely to be helpful in the clinical management of patients in preterm labor.

Objective: To investigate the association between gestational diabetes mellitus (GDM) and preterm birth subtypes. Methods: Based on the cohort of pregnant women in Anqing Prefectural Hospital, the pregnant women who received prenatal screening in the first or second trimesters were recruited into baseline cohorts; and followed up for them was conducted until delivery, and the information about their pregnancy status and outcomes were obtained through electronic medical record system and questionnaire surveys. The log-binomial regression model was used to explore the association between GDM and preterm birth [iatrogenic preterm birth, spontaneous preterm birth (preterm premature rupture of membranes and preterm labor)]. For multiple confounding factors, the propensity score correction model was used to compute the adjusted association. Results: Among the 2 031 pregnant women with a singleton delivery, the incidence of GDM and preterm birth were 10.0% (204 cases) and 4.4% (90 cases) respectively. The proportions of iatrogenic preterm birth and spontaneous preterm birth in the GDM group (n=204) were 1.5% and 5.9% respectively, while the proportions in non-GDM group (n=1 827) were 0.9% and 3.2% respectively, and the difference in the proportion of spontaneous preterm birth between the two groups was significant (P=0.048). Subtypes of spontaneous preterm were further analyzed, and the results showed that the proportions of preterm premature rupture of membranes and preterm labor in the GDM group were 4.9% and 1.0% respectively, while the proportions in the non-GDM group were 2.1% and 1.1% respectively. It showed that the risk of preterm premature rupture of membranes in GDM pregnant women was 2.34 times (aRR=2.34, 95%CI: 1.16-4.69) higher than that in non-GDM pregnant women. Conclusions: Our results showed that GDM might increase the risk of preterm premature rupture of membranes. No significant increase in the proportion of preterm labor in pregnant women with GDM was found.

OBJECTIVES: To investigate the effect of auriculotherapy on reducing labor anxiety. METHODS: In this randomized clinical trial, 166 nulliparous pregnant women admitted to the Labor Ward of Izadi Hospital in Qom, Iran were included and assigned to two groups by randomized block design. In the intervention group (83 cases), auriculotherapy in "Shenmen, Thalamic, Zero, Brain, and Brain stem" was performed in dilatations of 4, 6 and 8 cm, between the contractions for 30 s in both ears at interval 1 h. While the control group received routine care. The Spielberger Inventory were completed pre- and post-interventions. RESULTS: The auriculotherapy was effective to reduce anxiety state in the intervention group compared to the control group (P=0.001). The score of state anxiety in the intervention group reduced for 7.0, 8.0 and 11.0 U in 4, 6, and 8 cm dilatations after the intervention. The score of trait anxiety in the intervention group reduced for 3.8, 4.0 and 8.3 U in 4, 6, and 8 cm dilatations after the intervention. There was no significant difference of delivery mode and newborns' weight and Apgar score between groups (P>0.05). No adverse postpartum outcome such as hemorrhage has been observed in both groups. CONCLUSION Since most women are anxious during labor, it seems that auriculotherapy can be an easy and safe method to reduce labor anxiety. (Trial registration No. irct20121230011944n4).

OBJECTIVE: To explore if acupoint injection can improve analgesic effects or delivery outcomes in parturients who received combined spinal-epidural analgesia (CSEA) and patient-controlled epidural analgesia (PCEA) for labor analgesia. METHODS: A total of 307 participants were prospectively collected from July 2017 to December 2019. The participants were randomized into the combined acupoint injection with CSEA plus PCEA group (AICP group, n=168) and CSEA plus PCEA group (CP group, n=139) for labor analgesia using a random number table. Both groups received CSEA plus PCEA at cervical dilation 3 cm during labor process, and parturients of the AICP group were implemented acupoint injection for which bilateral acupoint of Zusanli (ST 36) and Sanyinjiao (SP 6) were selected in addition. The primary outcome was Visual Analogue Scale (VAS) score, and the secondary outcomes were obstetric outcomes and requirement of anesthetics doses. Safety evaluations were performed after intervention. RESULTS: The VAS scores were significantly lower in the AICP group than in the CP group at 10, 30, 60, and 120 min after labor analgesia (all P<0.05). The latent phase of the AICP group was shorter than that of the CP group (P<0.05). There were less additional anesthetics consumption, lower incidences of uterine atony, fever, pruritus and urinary retention in the AICP group than those in the CP group (all P<0.05). CONCLUSION Acupoint injection combined CSEA plus PCEA for labor analgesia can decrease the anesthetic consumption, improve analgesic quality, and reduce adverse reactions in the parturients.

OBJECTIVE: To investigate the birth condition of preterm infants and the causes of preterm birth in Henan Province, China, and to provide a basis for the prevention and treatment of preterm birth. METHODS: An epidemiological investigation was conducted for live-birth preterm infants who were born in 53 hospitals in 17 cities of Henan Province from January 1, 2019 to December 31, 2019 to investigate the incidence rate of preterm birth, the distribution of gestational age and birth weight, the use of antenatal glucocorticoids, and the causes of preterm birth. RESULTS: The incidence rate of preterm birth was 5.84% (12 406/212 438) in the 53 hospitals. The proportions of preterm infants with gestational ages of < 28 weeks, 28 - < 32 weeks, 32 - < 34 weeks, and 34 - < 37 weeks were 1.58% (196/12 406), 11.46% (1 422/12 406), 15.18% (1 883/12 406), and 71.78% (8 905/12 406) respectively. The proportions of preterm infants with birth weights of < 1 000 g, 1 000- < 1 500 g, 1 500- < 2 500 g, 2 500- < 4 000 g, and ≥ 4 000 g were 1.95% (240/12 313), 8.54% (1 051/12 313), 49.53% (6 099/12 313), 39.59% (4 875/12 313), and 0.39% (48/12 313) respectively. The infants born by natural labor accounted for 28.76% (3 568/12 406), and those born by cesarean section accounted for 70.38% (8 731/12 406). The rate of use of antenatal glucocorticoids was 52.52% (6 293/11 983) for preterm infants and 68.69% (2 319/3 376) for the preterm infants with a gestational age of < 34 weeks. Iatrogenic preterm labor was the leading cause of preterm birth[40.06% (4 915/12 270)], followed by spontaneous preterm birth[30.16% (3 701/12 270)] and preterm birth due to premature rupture of membranes[29.78% (3 654/12 270)]. The top three causes of iatrogenic preterm birth were hypertensive disorders of pregnancy[47.12% (2 316/4 915)], fetal intrauterine distress[22.85% (1 123/4 915)], and placenta previa/placental abruption[18.07% (888/4 915)]. CONCLUSIONS There is a relatively low incidence rate of preterm birth in Henan Province, and late preterm infants account for a relatively high proportion. Iatrogenic preterm birth is the main cause of preterm birth in Henan Province, and hypertensive disorders of pregnancy and fetal intrauterine distress are the main causes of iatrogenic preterm birth.

OBJECTIVE: To observe effect of magnetic beads auricular point sticking therapy on intrapartum fever in primipara with epidural labor analgesia and explore its possible mechanism. METHODS: A total of 160 primipara were randomly divided into an observation group (80 cases, 12 cases dropped off ) and a control group (80 cases, 15 cases dropped off ). The primipara in the control group received epidural labor analgesia. In the observation group, 15 min after epidural labor analgesia was performed, magnetic beads auricular point sticking therapy was given at shenmen (TF RESULTS: There was no significant difference in tympanic temperature in the observation group at each time point ( CONCLUSION Magnetic beads auricular point sticking therapy can reduce the amount of anesthetics, decrease the effect of epidural analgesia on primipara's body temperature regulation and labor progress, and lower the incidence of fever during labor analgesia by regulating the level of inflammatory response in the primipara.

BACKGROUND AND PURPOSE: Restless legs syndrome (RLS) is a common sleep-related neurological disorder that affects the quality of sleep. This study aimed to estimate the prevalence, predictive factors, and natural course of RLS, and its effect on sleep quality in pregnant Thai women. METHODS: A cross-sectional study that included 214 pregnant women was performed. RLS was diagnosed according to the revised criteria of the International RLS Study Group (IRLSSG). General demographic and antenatal-care data were reviewed. Scores on the Thai versions of the Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index, and the IRLSSG Rating Scale were determined. RESULTS: RLS was diagnosed in 24 of the pregnant women (11.2%): 4.2%, 25.0%, and 70.8% in the first, second, and third trimesters, respectively. Multiple logistic regression analysis revealed that a hemoglobin level (Hb) less than 11 g/dL [odds ratio (OR)=3.21, 95% CI=1.27–8.13] and a history of RLS (OR=16.62, 95% CI=1.52–181.32) were associated with RLS during pregnancy. Subjects with RLS significantly had higher Thai-ESS scores (p < 0.01). All subjects with RLS had severe symptoms that subsided within 1 week after delivery. No immediate labor complication was associated with RLS. CONCLUSIONS: Our study has confirmed a high prevalence of RLS and its impacts on sleep in pregnant women. An Hb of less than 11 g/dL and a history of RLS are predictive factors for RLS developing during pregnancy. Pregnancy-related RLS has a benign course and usually disappears within 1 week after delivery.

OBJECTIVE: To critically compare the benefits and risks of labor induction versus spontaneous labor in uncomplicated nulliparous women at 39 or more weeks of gestation. METHODS: We conducted a retrospective, observational study of 237 nulliparous women who were at 39 or more weeks of a singleton pregnancy with vertex presentation and intact membranes. We compared maternal outcomes including the Cesarean section rate and neonatal outcomes in the induced labor and spontaneous labor groups. RESULTS: Among the 237 women, 199 delivered vaginally (84.0%). The spontaneous labor group and induced labor group had a similar incidence of Cesarean delivery (17.7% vs. 12.3%, P=0.300). The length of stay and blood loss during delivery were also similar between the groups (4.3±1.5 vs. 3.9±1.5 days and 1.9±1.3 vs. 1.8±1.0 mg/sL, respectively; all P > 0.05). Regarding neonatal outcomes, the rate of meconium-stained amniotic fluid, Apgar score < 7 at 5 minutes, and intubation rate were similar between the groups (18.9% vs. 24.7%, 7.9% vs. 4.1%, and 6.1% vs. 4.4%, respectively, all P > 0.05). Only the neonatal intensive care unit admission rate was significantly lower in the induction group than in the spontaneous labor group (28.0% vs. 13.2%, P=0.001). CONCLUSION: Maternal adverse outcomes of labor induction at 39 weeks of gestation were similar to those in a spontaneous labor group in uncomplicated nulliparous women. Neonatal adverse events were also similar between the groups. It may be acceptable to schedule labor induction as long as 7 days before the estimated date, even when the indication is only relative.
