To understand the sequential response of the autonomic nervous system to pregnancy, we studied heart rate variability in 23 first trimester, 23 second trimester and 21 third trimester pregnant women. Twenty non-pregnant women were recruited as controls. Time and frequency domain measures of heart rate variability in three recumbent positions were compared. We found that normalized high-frequenc...

purpose: in this study the effect of iron supplmentation on hemoglobin and hematocrit in pregnant women with hb>13.2 g/dl was investigated. material and methods: in this experimental clincal study, the effect of iron supplementation on hemoglobin and hematocrit in pregnant women with hb>13.2 g/dl and ferritin> 14.3 μg/l during the 13th- 18th pregnancy week was studied. eighty seven women havin...

BACKGROUND Thyroid hormones are critical for fetal development and growth. Whether prenatal exposure to fine particle air pollution (≤ 2.5 μm; PM2.5) affects fetal thyroid function and what the impact is on birth weight in normal healthy pregnancies have not been studied yet. OBJECTIVES We studied the impact of third-trimester PM2.5 exposure on fetal and maternal thyroid hormones and their me...

Although recent studies have demonstrated that microRNAs (miRNAs or miRs) regulate fundamental natural killer (NK) cellular processes, including cytotoxicity and cytokine production, little is known about the miRNA-gene regulatory relationships in maternal peripheral blood NK (pNK) cells during pregnancy. In the present study, to determine the roles of miRNAs within gene regulatory networks of ...

Primary hyperparathyroidism (PHPT) is rare condition during pregnancy; however, it can carry significant risks to both mother and foetus during and after the pregnancy. The definitive treatment is parathyroidectomy undertaken preferably in the second or early third trimester. A case of asymptomatic PHPT diagnosed and treated by parathyroidectomy in the third trimester is described.

BACKGROUND Although vitamin D insufficiency is prevalent in the community, only a few population-based studies have measured serum 25-hydroxy-vitamin D (25OHD) levels during pregnancy and in newborns. Maternal vitamin D deficiency has been linked to pregnancy complications, as well as hypocalcaemia and rickets in the newborn. Here, the authors report third-trimester maternal and newborn-serum 2...

Background: Various studies have come to contradictory results regarding the relationship between maternal hemoglobin (Hb) level and adverse pregnancy outcomes. The present study aimed to investigate the birth outcomes among pregnant women who had normal hemoglobin levels in the first trimester of their pregnancy. Patients and Methods: In this prospective study, 108 healthy pregnant women wi...

The results showed that incidence of asthma, allergic rhinitis, and eczema in children was associated with maternal exposure to traffic-related pollutant NO2 throughout pregnancy. After adjustment for other pollutants and trimesters, the researchers found the association was significant only in specific trimesters: the first trimester for eczema, the second trimester for asthma, and the third t...

BACKGROUND The objective of this study was to evaluate the clinical outcomes and to discuss the management of women presenting with an invasive cervical cancer during pregnancy. PATIENTS AND METHODS We retrospectively reviewed patients treated for an invasive cervical cancer diagnosed during pregnancy between 1985 and 2000 in our institution. RESULTS Twenty-one pregnant patients among a tot...
