Pregnancy

Scientific studies (review articles) on the relationship between diet/nutrients and pregnancy:
One swallow does not make a summer. A famous Dutch saying that could not be any more obvious. Just because one single scientific study about a certain topic makes certain claims, it does not necessarily mean it is true. On the other hand, a review article (a collection of scientific studies on a specific topic) of randomized, placebo-controlled double blind clinical trials (RCTs) will answer the following question:

Daily 10 to 66 mg iron supplementation during pregnancy improve maternal haematological status and birth weight

Objectives:
Does iron supplementation during pregnancy improve maternal haematological status and birth weight?

Study design:
This review article included 48 RCTs (17,793 women) and 44 cohort studies (1,851,682 women).

The dose of iron in RCTs ranged from 10 mg to 240 mg daily. Duration of supplementation varied from 7 to 8 weeks up to 30 weeks during pregnancy.

Significant heterogeneity existed for several outcomes that could not be explained substantially by pre-specified subgroups.

High serum copper level increase risk of preeclampsia in Asian pregnant women

Objectives:
Epidemiological studies evaluating the associations between serum copper and ratios of copper/zinc (Cu/Zn) and the preeclampsia (PE) risk in Asian population have produced inconsistent results. Therefore, this review article (meta-analysis) has been conducted.

Do a higher serum copper and ratios of Cu/Zn increase the preeclampsia risk in Asian population?

Serum ceruloplasmin may be a useful screening and follow-up tool for developing preeclampsia

Objectives:
Are there differences in serum ceruloplasmin levels between patients with preeclampsia and healthy controls?

Study design:
This review article included 15 studies, with a total number of 1927 women.

Results and conclusions:
The investigators found that maternal serum ceruloplasmin concentration was significantly higher in preeclamptic than in the healthy pregnant women [MD = 12.57 mg/dL, 95% CI = 8.81 to 16.33].
