Breast Stimulation Helps Induce Labor and Reduce Bleeding: In six random assignment trials covering 719 women, there was a significant reduction in the number of women not in labor at 72 hours (62.7% versus 93.6%, relative risk (RR) 0.67, ). This result was not significant in women with an unfavorable cervix. A major reduction in the rate of postpartum hemorrhage was reported (0.7% versus 6%, RR 0.16). No significant difference was detected in the caesarean section rate (9% versus 10%, RR 0.90). There were no instances of uterine hyperstimulation. When comparing breast stimulation with oxytocin alone the analysis found no difference in caesarean section rates (28% versus 47%, RR 0.60).

Calcium Supplement Prenatally Lowers Infant BP: One group of pregnant women took 2000 mg of calcium per day starting in the second trimester through delivery, and another took a placebo. Dr. Dan Hatton's team measured blood pressure in 260 of the children at the age of 3 months, and in 57 at age 2. Infants born to women who took calcium supplements had systolic blood pressure 2.2 mm Hg lower than those whose mothers received placebo. By age 2, the difference was even greater, with the supplement group having systolic blood pressure 4.8 mm Hg lower. Other studies similar results even with lower amounts and lasting up to 9 years.

Castor Oil Induces Contractions: Fifty-two women received castor oil and 48 were assigned no treatment. Following administration of castor oil, 30 of 52 women (57.7%) began active labor compared to 2 of 48 (4.2%) receiving no treatment. When castor oil was successful, 83.3% (25/30) of the women delivered vaginally. Altern Ther Health Med 2000 Jan;6(1):77-9

Delivery: Patient-Controlled Epidural Analgesia: 220 ASA I-II women receiving epidural analgesia during active labor (cervical dilation <5 cm) were randomly assigned in a DB study to four treatment groups (n=30 in each). Analgesia was maintained with a Patient-controlled epidural analgesia/continuous infusion (PCEA/CI) pump using bupivacaine 0.0625%+sufentanil 0.35 mug/mL. PCEA settings were: group A: CI 10 mL/h, PCEA bolus 6 mL, 8-min lockout; group B: CI 10 mL/h, PCEA bolus 12 mL, 16-min lockout; group C: CI 15 mL/h, PCEA bolus 6 mL, 8-min lockout; group D: CI 15 mL/h, PCEA bolus 12 mL, 16-min lockout. In groups A, B, C and D, 76, 77, 75 and 85% of women, required no physician rescue boluses. Pain scores were low and maternal satisfaction was high in all groups, with minimal differences among them. Spontaneous vaginal delivery occurred in 78% of patients overall, instrumental (forceps or vacuum) delivery in 10% and cesarean section in 12%.

DHA in Pregnancy Probably Helps: A DB study with 291 women taking egg DHA 33 mg/d or 133 mg/d. After controlling for risk factors, gestation increased by 6.0 days (P =.009) in the higher docosahexaenoic acid group. Birth weight, length, and head circumference increased almost to statistical significance (P =.06-.18), although the increases could be clinically important indications of enhanced intrauterine growth. No safety concerns were found. U Kansas. A randomized trial of docosahexaenoic acid supplementation during the third trimester of pregnancy. Smuts CM, Huang M, et al. Obstet Gynecol. 2003 Mar;101(3):469-79. (Ed: This is a great study, but the levels of DHA could have been higher. Also, DHA from fish or fish oil is more available. Everyone from childhood should be eating fish and/or taking fish oil or its equivalent.)

Depression Common During Pregnancy: 3,472 women an average of 25 weeks pregnant. Slightly more than 20% signs of depression during the past seven days, Marcus, University of Michigan. 86% had not received any formal treatment, such as medication, psychotherapy or counseling. Only about one quarter of the women who reported being depressed during the past six months said they were currently being treated. May 22, ‘03 J Women's Health. 28% of all women had past history of major depressive episode, 40% of these were depressed when measured. These previously depressed were 5 times more likely to suffer depression with pregnancy than other women. 

Douching Dangerous: Douching increased low-birth-weight babies in a University of Rochester study of 4,665 women in US with about half douching regularly. Kevin Fiscella author says possibly due to vaginal infection arising when natural protective flora are killed. The percentage of low birth weight babies to  9.7% vs. 5.8% and controlled for income, race, martial, smoke, alcohol, and other. Other studies suggest douching increases ectopic pregnancy, infertility, and pelvic inflammatory disease. 27% US women douched regularly in 1995 (50% blacks, 21% whites). (12/98 ObGyn)

Fish Helps Prevent Premature Delivery: 8,000 Danish women during pregnancy to determine if seafood had an impact on early births. "Low consumption of fish was a strong risk factor for pre-term delivery and low birth weight," Pre-term deliveries fell from 7.1 percent in women who never ate fish to 1.9 percent in expectant mothers who ate fish at least once a week. BMJ 2/20/02

Fish: Moderate Fish or Fish Oil Consumption Best in Pregnancy: In a study of 491 healthy Icelandic mothers, infants of women in the lowest quartile of fish consumption weighed less (p = 0.036), were shorter (p < 0.001), and had a smaller head circumference (p < 0.001) at birth than those of women consuming higher amounts of fish. Infants of women in the highest quartile of fish oil intake (>/=1 tablespoon (11 ml)/day), consuming threefold the recommended dietary allowance of vitamin A and twofold that of vitamin D, were shorter (p = 0.036) and had a smaller head circumference (p = 0.003) than those of women consuming less. Infant size at birth increased with fish consumption, especially for women in the lower quartiles of consumption. Smaller birth size was also linked to the highest levels of fish oil intake. Constituents of fish and fish oil might affect birth size differently depending on the amount consumed.

Folic Acid Interfering Meds Increase Cleft Palates, Defects: Babies have 2-3 times heart, palate, urinary tract defects if mothers take interfering meds. Those on antibiotic trimethoprim or the high blood pressure medicine triamterene might be able to compensate by taking extra folic acid, but that may not help patients on phenobarbital, primidone, phenytoin or carbamazepine for epilepsy. NEJM 11/30/00.

Folic Acid Alone Did Better than Multivitamins: In a Johns Hopkins DB PC study of 4926 pregnant women and their 4130 infants in rural Nepal. In addition to vitamin A (1000 microg retinol equivalents), the intervention groups received either folic acid (FA; 400 microg), FA + iron (60 mg), FA + iron + zinc (30 mg), or multiple micronutrients (MNs; the foregoing plus 10 microg vitamin D, 10 mg vitamin E, 1.6 mg thiamine, 1.8 mg riboflavin, 2.2 mg vitamin B-6, 2.6 microg vitamin B-12, 100 mg vitamin C, 64 microg vitamin K, 20 mg niacin, 2 mg Cu, and 100 mg Mg). The control group received vitamin A only. None affected fetal loss and death of infants in the first three months of life was lowest with folic acid (RR 0.36) and highest with the multiple nutrients (RR 1.74).  Effects of maternal micronutrient supplementation on fetal loss and infant mortality: a cluster-randomized trial in Nepal.

Iron Supplement May Be Helpful: In a DB PC study of adolescent women 18 years or less in their first pregnancy, and adult women 19 years or older, who were found to be healthy and iron sufficient at their first prenatal visit, participants were randomized to receive iron supplementation (60 mg/day elemental iron) or placebo. Serum ferritin of 12 ng/mL or less with simultaneous hemoglobin of 11 g/dL or less defined IDA. When IDA occurred at the second trimester, a therapeutic supplement of 180 mg of elemental iron per day was started. 47% of all placebo-supplemented and 16% of all iron-supplemented patients exhibited IDA (p<0.001); 59% of adolescent placebo-supplemented and 20% of adolescent iron-supplemented patients exhibited IDA (p=0.021). Nausea, vomiting, diarrhea, and constipation were not significantly different in the iron supplemented group compared to the placebo group, and no significant differences were seen in maternal or neonatal health, but the number of women studied was limiting for analysis of these adverse events. The incidence of IDA during adolescent and adult pregnancies is substantially reduced with 60 mg of elemental iron per day. However, there remains no clear evidence that maternal or neonatal health will benefit from correcting these deficits. Prevention of Iron Deficiency Anemia in Adolescent and Adult Pregnancies.

Melanoma: Having More Children Protects Against Melanoma: A higher risk of reproductive system disorders, (which include benign tumors, endometriosis, dilation and curettage, hysterectomy, and other disorders requiring gynecologic biopsies) exist among women with cutaneous melanoma as compared to women with skin cancers: The odds ratio (OR) is 3.2, p = 0.049; as compared to a random sample of women with no melanoma or skin cancers, the OR is 3.9, p = 0.021. Confirming the observations of others, the authors found that melanoma was associated with red hair. The data also confirmed the finding that melanoma is associated with significantly fewer pregnancies. The mean numbers of pregnancies in the melanoma group is 1.83  compared to 2.99 in the skin cancer group and 2.93 in the random sample (p less than or equal to 0.05).

Nausea & Pregnancy: Anti-emetic medication appears to reduce the frequency of nausea in early pregnancy. There is some evidence of adverse effects, but there is very little information on effects on fetal outcomes. Of newer treatments, pyridoxine (vitamin B6) appears to be more effective in reducing the severity of nausea. The results from trials of P6 acupressure are equivocal. The results of the trial using adrenocorticotropic hormone to treat hyperemesis gravidarum show no evidence of benefit. Ginger may be of benefit, but the evidence so far is weak.

Nausea & Pregnancy: B-6, Ginger, Multivitamin, Doxylamine: Anti-emetic medication appears to reduce the frequency of nausea in early pregnancy. There is some evidence of adverse effects, but there is very little information on effects on fetal outcomes. Of newer treatments, pyridoxine (vitamin B6) appears to be more effective in reducing the severity of nausea. The results from trials of P6 acupressure are equivocal. The results of the trial using adrenocorticotropic hormone to treat hyperemesis gravidarum show no evidence of benefit. Ginger may be of benefit, but the evidence so far is weak. Cochrane Database Syst Rev 2000;(2):CD000145; Two randomized trials of vitamin B6 have shown a benefit in reducing nausea and vomiting of pregnancy (NVP). Women taking periconceptional multivitamins are less likely to have severe NVP. The combination of vitamin B(6) and doxylamine (previously marketed in the United States as Bendectin) has been shown to be safe for the fetus and effective in reducing NVP. Ginger was shown, in 2 studies, to reduce NVP. Vitamin B(1) (thiamine) deficiency can lead to Wernicke's encephalopathy in women with severe NVP. Replacement is needed for all women with vomiting of more than 3 weeks' duration. U Iowa. Am J Obstet Gynecol 2002 May;185(5 Suppl Understanding):S253.

Osteoporosis Not Increased by Pregnancy, Breast Feeding: Women even with moderate calcium intakes have no long-term harm to their skeletons or risk of osteoporosis from pregnancy and lactation. Lancet 8/15/98

Osteoporosis: Mothers Low in Vitamin D Affect Body Mineral Density of Offspring: In a 9-year follow-up study of 198 newborns, 31% mothers had insufficient and 18% had deficient circulating 25(OH)-vitamin D during late pregnancy. Low vitamin D in mothers during late pregnancy was associated with reduced whole-body (p=0.0088) and lumbar-spine (p=0.03) bone-mineral content in children at age 9 years. Both the estimated exposure to ultraviolet B radiation during late pregnancy and the maternal use of vitamin D supplements predicted maternal 25(OH)-vitamin D concentration (p<0.0001 and p=0.0110, respectively) and childhood bone mass (p=0.0267). Reduced concentration of umbilical-venous calcium also predicted reduced childhood bone mass (p=0.0286).  Vitamin D supplementation of pregnant women, especially during winter months, could lead to longlasting reductions in the risk of osteoporotic fracture in their offspring.

Pre-Eclampsia Risk Reduced by Diet: In a case-control study of 172 preeclamptics and 339 normotensive pregnant women, fiber intake was inversely associated with the risk of preeclampsia. When extreme quartiles of total fiber intake were compared, the odds ratio (OR) for preeclampsia was 0.46, a 54% reduction in risk. The multivariate OR for preeclampsia for women in the top quartile of potassium intake (> 4.1 g/d) versus the lowest quartile (< 2.4 g/d) was 0.49. There was some evidence ofa reduced risk of preeclampsia with a high intake of magnesium and calcium, though these results were not statistically significant. Intake offruits and vegetables, low-fat dairy products, total cereal and dark bread were each associated with a reduced risk of preeclampsia.

Progesterone Cuts Premature Deliveries: hydroxyprogesterone caproate, or 17P, can reduce preterm births by up to one-third, according to a study in the June 12, 2003, edition of the New England Journal of Medicine. A University of Utah study of 463 women with first pregnancy preterm DB PC started in 16-20^th week. 36% vs 54% had 2^nd pre-term. Progesterone relaxes the smooth muscle wall of the uterus, blocks the action of oxytocin, a hormone that makes the uterus contract, and inhibits the formation of gap junctions. Gap junctions are connections that allow the muscle cells in the uterus to communicate with each other so they can contract at the same time.

Prostaglandin E Gel for Dystocia Increases C-Sections: In a DB PC study of 332 nulliparous women with spontaneous labor at term who had progressed <2 cm of cervical dilation in the 4 hours following the diagnosis of labor were randomly assigned to receive a single dose of either 1 mg or 2 mg  PgE(2) vaginal gel or placebo gel. Dystocia resolved slightly more often after PgE(2) 1 mg (49%), and PgE(2) 2 mg (49%), compared with placebo (32%). Hyperstimulation was markedly increased after PgE(2) 2 mg treatment (15%), RR 5.6, but less after PgE(2) 1 mg (5.4%), RR 1.9 when compared with placebo (2.8%). There was an increase in caesarean sections performed in the second stage of labour in the PgE(2) groups versus placebo. There were no differences in measures of maternal or neonatal morbidity.

Vitamins C and E Helped Delay Delivery in Premature Rupture: In a DB PC study of 60 women with singleton pregnancies of 26 to 34 weeks' duration and preterm premature rupture of membranes, vitamin C (500 mg/day) and vitamin E (400 IU/day) did not reduce the number of cases of chorioamnionitis, early neonatal sepsis, and respiratory distress syndrome. However, the number of days of delayed delivery (latency) was increased to 10.5 days vs. 3.5 days (P=0.03) for placebo. All women received 2 doses of betamethasone in the first 24 h after admission as well as broad-spectrum antibiotic prophylaxis.  Vitamins C and E in the latency period in women with preterm premature rupture of membranes.

Vitamin K: Give Mothers Who Will Deliver Early Vitamin K: Infants less than 35 weeks' gestation age are susceptible to periventricular-intraventricular hemorrhage. In a randomized study of 90 pregnant women in preterm labor at less than 35 weeks, antenatal vitamin K1 10 mg per day injection intramuscularly or intravenously for 2-7 days resulted in less infant brain hemmorrhage: vitamin K 32% vs. controls 52% (P = 0.036), and a lower frequency of severe PIVH was 5% vs. 20% (P = 0.038). Liu J, et al. Beijing Obstetrics and Gynecology Hospital. . J Perinat Med 2006;34(2):173-6. Ed: Since vitamin K has a wide safety margin, it would seem sensible to give in to all pregnant women late in pregnancy.  However, I haven't seen this recommendation yet.

Vitamins Cuts Birth Defects: Ginecol Obstet Mex 2000 Dec;68:476-81 found less anencephaly with multivitamin. Cleft Palate Craniofac J 2001 Jan;38(1):76-83 found marginally lower cleft palate. Third study found fewer isolated major heart defects in an Atlanta study under multivitamins. Also cuts urinary tract defects.

Alcoholism Risk May be Lowered by Vitamin K at Birth: Taking advantage of a serendipitous event in the history of treating newborns, two thirds of the original 330 subjects in this study were high-risk sons of alcoholic fathers. Of 238 completing the 30-year follow-up, 44 received vitamin K supplementation at birth; 161 were considered high risk, and 66 were categorized as having lower birth weight (<6 lbs). Vitamin K treatment, inherited risk and low birth weight each independently predicted alcohol dependence and problem drinking. Vitamin K treatment was associated with significantly lower rates of alcohol dependence and fewer symptoms of problem drinking. Vitamin K might reduce early postnatal hemorrhage and oxidative brain damage, and thus lower the risk of alcoholism. Neonatal vitamin K might reduce vulnerability to alcohol dependence in Danish men.
