Abstract The objective of this study was to investigate whether relaxin might be involved in placental protein 14 (PP14) secretion by measuring serum levels of PP14 during labour and post partum in normal women with a term pregnancy given vaginal human recombinant relaxin (rhRlx) gel for induction of labour. A randomized double-blind controlled trial was conducted on 11 women with a singleton pregnancy at term admitted for induction of labour. Comparison of serum PP14 and relaxin concentrations in the control and treated groups of subjects revealed that there was an increase in serum relaxin concentrations in women receiving 3 mg or 6 mg relaxin. There was no difference in serum PP14 levels between the control and treatment groups. These findings do not support the hypothesis that relaxin is involved in the control of PP14 secretion. However, the failure of any response might be a consequence of the very small increase in systemic levels of relaxin produced by topical vaginal administration of rhRlx. Furthermore, these measurements were made in late pregnancy and hence may not relate to the events in early pregnancy, when serum levels of PP14 are maximal.

Mastitis is considered one of the main reasons for unwanted breastfeeding cessation. This study aimed to investigate the preventive effect of the probiotic strain Ligilactobacillus salivarius PS2 on the occurrence of mastitis in lactating women. In this multicountry, multicenter, randomized, double-blind, placebo-controlled trial, 328 women were assigned to the probiotic or the placebo group. The intervention started from the 35th week of pregnancy until week 12 post-partum. The primary outcome was the incidence (hazard) rate of mastitis, defined as the presence of at least two of the following symptoms: breast pain, breast erythema, breast engorgement not relieved by breastfeeding, and temperature > 38 °C. The probability of being free of mastitis during the study was higher in the probiotic than in the placebo group (p = 0.022, Kaplan–Meier log rank test) with 9 mastitis cases (6%) vs. 20 mastitis cases (14%), respectively. The hazard ratio of the incidence of mastitis between both study groups was 0.41 (0.190–0.915; p = 0.029), indicating that women in the probiotic group were 58% less likely to experience mastitis. In conclusion, supplementation of L. salivarius PS2 during late pregnancy and early lactation was safe and effective in preventing mastitis, which is one of the main barriers for continuing breastfeeding.

BackgroundWomen who are positive for thyroid antibodies in early gestation are prone to post-partum depression, apparently independent of thyroid dysfunction, as measured by serum levels of free thyroxine, free triodothyroxine and thyroid-stimulating hormone. This finding may be due to infrequent monitoring of thyroid function, because hyperthyroidism, hypothyroidism and combinations of both may occur post-partum.AimsTo test the hypothesis that stabilising thyroid function post-partum by administering daily thyroxine reduces the rate of occurrence and severity of associated depression.MethodIn a randomised double-blind placebo-controlled trial, 100 of thyroxine or placebo was given daily to 446 thyroid-antibody-positive women (342 of whom were compliant) from 6 weeks to 6 month spost-partum, assessing their psychiatric and thyroid status at 4-weeklyintervals.ResultsThere was no evidence that thyroxine had any effect on the occurrence of depression. The 6-month period prevalence of depression was similar to that reported previously.ConclusionsThe excess of depression in thyroid-antibody-positive women in the post-partum period is not corrected by daily administration of thyroxine.

A double-blind randomised controlled trial, comparing pramoxine hydrochloride 1 per cent and hydrocortisone acetate 1 per cent in a mucoadhesive foam base, with simple aqueous foam (B.P.), in relieving episiotomy discomfort and episiotomy healing in 40 patients was carried out. Simple aqueous foam was more effective with regard to wound healing and episiotomy discomfort as measured by analgesic consumption. Pramoxine and hydrocortisone foam offers no advantage over simple aqueous foam in the treatment of post partum episiotomy discomfort.

AbstractThis study compared hemodynamic changes and occurrence of complications following oxytocin administration with a prior injection of phenylephrine 100 μg or normal saline during elective cesarean section. Sixty-six healthy term parturients with uncomplicated, singleton pregnancy undergoing elective cesarean section under spinal anesthesia were studied. They received either intravenous phenylephrine 100 μg or normal saline before oxytocin 3 IU was administered over 30 seconds. Oxytocin dose was repeated depending on the adequacy of uterine tone. There was no significant change in systolic, diastolic, and mean arterial pressures during the initial 3 minutes following oxytocin administration in the phenylephrine group but a significant fall in mean and diastolic pressures in the saline group. Heart rate did not change significantly, and no significant complications occurred in either of the groups. To conclude, phenylephrine 100 μg administered before oxytocin injection maintained hemodynamic parameters better than normal saline injection during elective cesarean section.

Purpose: While an increasing number of studies demonstrate the importance of vitamin D for athletic performance, the effects of any type of exercise on vitamin D metabolism are poorly characterized. We aimed to identify the responses of some vitamin D metabolites to ultra-marathon runs. Methods: A repeated-measures design was implemented, in which 27 amateur runners were assigned into two groups: those who received a single dose of vitamin D3 (150,000 IU) 24 h before the start of the marathon (n = 13) and those (n = 14) who received a placebo. Blood samples were collected 24 h before, immediately after, and 24 h after the run. Results: In both groups of runners, serum 25(OH)D3, 24,25(OH)2D3, and 3-epi-25(OH)D3 levels significantly increased by 83%, 63%, and 182% after the ultra-marathon, respectively. The increase was most pronounced in the vitamin D group. Body mass and fat mass significantly decreased after the run in both groups. Conclusions: Ultra-marathon induces the mobilization of vitamin D into the blood. Furthermore, the 24,25(OH)2D3 and 3-epi-25(OH)D3 increases imply that the exercise stimulates vitamin D metabolism.

1. A serial study of renal clearance of urate and inulin was made in thirteen normal women in early, mid and late pregnancy and 6–15 weeks after delivery. 2. The mean serum urate concentration was low in early and mid pregnancy but rose in late pregnancy towards the control value. 3. Clearances of urate and inulin were consistently elevated throughout pregnancy to about 150% of the post-partum values. The ratio of clearance of urate to clearance of inulin was the same in pregnancy as it was after the puerperium. 4. The urinary excretion of urate was increased only in late pregnancy.

Docosahexaenoic acid (DHA) accumulates in the fetal brain during pregnancy and is thought to have a role in supporting neurodevelopment. We conducted a multicenter, double-blind, randomized controlled trial in women with a singleton pregnancy who were <21 weeks’ gestation at trial entry. Women were provided with 800 mg DHA/day or a placebo supplement from trial entry until birth. When children reached seven years of age, we invited parents to complete the Strengths and Difficulties Questionnaire (SDQ), the Behavior Rating Inventory of Executive Function (BRIEF), and the Conners 3rd Edition Attention-Deficit Hyperactivity Disorder (ADHD) Index to assess child behavior and behavioral manifestations of executive dysfunction. There were 543 parent–child pairs (85% of those eligible) that participated in the follow-up. Scores were worse in the DHA group than the placebo group for the BRIEF Global Executive, Behavioral Regulation and Metacognition Indexes, and the Shift, Inhibit, Monitor, Working Memory, and Organization of Materials scales, as well as for the Conners 3 ADHD index, and the SDQ Total Difficulties score, Hyperactivity/Inattention score, and Peer Relationship Problems score. In this healthy, largely term-born sample of children, prenatal DHA supplementation conferred no advantage to childhood behavior, and instead appeared to have an adverse effect on behavioral functioning, as assessed by standardized parental report scales.
