Hypertension in pregnancy as an early sex-specific risk factor for cardiovascular diseases: evidence and awareness.

Despite being a physiological condition, human pregnancy is known to cause numerous complications that can endanger the life of the mother and the fetus alike. While the majority of complications are mostly limited within the peripartum period, more and more information is available about persistently higher short- and long-term cardiovascular risk after a pregnancy complicated by a hypertensive disorder. There is evidence that women after gestational hypertension or preeclampsia are more likely to develop arterial hypertension, coronary atherosclerosis, myocardial infarction, stroke, peripheral artery disease, and even diabetes mellitus and venous thromboembolism years after the target pregnancy. This has urged some authors to view hypertensive disorders of pregnancy as a "stress test" for the maternal organism that unmasks latent endothelial dysfunction. An explanation is sought in the presence of common risk factors and underlying pathological pathways with cardiovascular diseases, although a certain etiological mechanism for the development of hypertensive disorders in pregnancy has not been established yet. More attention is needed towards the follow-up of women after a hypertensive pregnancy as it could be an opportunity for early prevention of cardiovascular diseases.

Mermaid syndrome associated with VACTERL-H syndrome.

Mermaid syndrome or sirenomelia is an extremely rare congenital malformation with an incidence between 1.5 and 4.2 per 1,000,000 pregnancies. Association of mermaid syndrome with VACTERL-H syndrome is extremely rare, with only two cases reported so far in the literature. We present a new case of type I sirenomelia associated with VACTERL-H syndrome and review the relevant literature. A 15-year-old female patient was admitted to the Department of Pathological Pregnancy at St George University Hospital, Plovdiv with progredient abortion during her first pregnancy. She had low socioeconomic status, negative history of concomitant diseases and addictions. The patient avoided prophylactic intake of folic acid during her pregnancy. Prenatal ultrasound found a malformative fetus. Consequently, magnetic resonance imaging was performed which established the presence of hydrocephalus and defects in the lower part of the spine. These pathological findings indicated interruption of pregnancy at 20 weeks of gestation. The fetopathological examination found sirenomelia type I associated with myelomeningocele, hydrocephalus, anal imperforation, single umbilical artery, bilateral renal and ureteric agenesis, bladder agenesis, tracheo-esophageal fistula, agenesis of external genitals, monkey fold of the left palm of the hand, also known as VACTERL-H syndrome.Our case demonstrates that mermaid syndrome and VACTERL-H syndrome represent different manifestations of a single pathological process that results in disorders of the blastogenesis at different stages during embryonic development.

High-sensitivity CRP levels in women with gestational hypertension, preeclampsia and in normotensive pregnant women and its correlations.

INTRODUCTION: Gestational hypertension is a less investigated hypertensive disorder of pregnancy than preeclampsia, but evidence exists of an unfavourable cardiovascular profile for women after such a pregnancy. AIM: To determine serum high-sensitivity C-reactive protein (hs-CRP) levels in women with preeclampsia, gestational hypertension, and in normotensive pregnancy in order to assess the cardiovascular implications and to examine its correlations with some characteristics of women. MATERIALS AND METHODS: Thirty-six women with gestational hypertension, thirty-seven with preeclampsia, and fifty maternal and gestational age-matched controls were included in a single-center prospective clinical-epidemiological study. Serum hs-CRP levels were determined using ELISA method. RESULTS: Significantly higher hs-CRP levels were found in the gestational hypertension group than in the controls (p=0.043), but not in the preeclampsia group (p=0.445). The levels between the two pathological groups did not differ significantly (p=0.247). Odds ratio for hs-CRP levels higher than the provided cut-off was 3.31 (95% CI 1.32-8.29) for the presence of gestational hypertension. In the normotensive pregnant women, the hs-CRP levels had a positive correlation with BSA, pre-pregnancy and current BMI, but such correlations were absent in the hypertensive groups. There were no correlations with the maternal or gestational age, current weight gain in any of the groups or with the highest detected blood pressure in the pathological groups. These levels did not differ according to gravidity, smoking status and smoking during pregnancy. CONCLUSIONS: Elevation of hs-CRP was more pronounced in women with gestational hypertension than in women with preeclampsia, which could indicate a different pathophysiological mechanism and a higher cardiovascular risk for those women.

Vulvovaginal Candidiasis in Pregnant Women and its Importance for Candida Colonization of Newborns.

UNLABELLED: Vulvovaginal candidiasis is the second most common cause of vaginitis worldwide (after bacterial candidiasis). Maternal vulvovaginal candidiasis is a major risk factor for Candida colonization and infection of the infant where prognosis depends on different predisposing factors. The aim of this study was to determine the incidence and the etiological structure of vulvovaginal candidiasis in pregnant women and its impact on Candida colonization of newborns. MATERIALS AND METHODS: Samples of vaginal secretions from 80 healthy pregnant women who were clinically suspicious for Candida vaginitis were collected within 48 hours before delivery. Samples for probable Candida colonization from the oral mucosa and feces were collected from their newborns within 47-72 hours after birth. Samples were plated on Sabouraud agar, followed by species identification by API Candida yeast assay. RESULTS: Twenty-three (28.75 ± 5.06%) of the evaluated pregnant women were positive for Candida spp. Positive samples for Candida colonization were found in 18 (22.22 ± 4.62%) of the examined 81 newborns (one pair of twins) from mothers who were clinically suspicious for vaginal candidiasis. Isolates of the newborns were 100% identical to those of the mothers' vaginal secretion. Candida albicans was the predominant species identified in the pregnant women (91.67 ± 0.06%) and in the neonates (83.33±8.78%).

Estrogen receptors--known and unknown biological functions.

The present literature review includes the data available from 1995 to 2005 about the biological functions of estrogen receptors (ERs) and their role in tumorigenesis. The domain organisation,and cell and tissue localization of two estrogen receptors are described. The article reviews the well known function of these receptors as transcription factors and their less familiar extracellular "non-genome" effects. Because of their stimulating effect on cell proliferation estrogens are supposed to actively participate in the genesis and development of some malignant conditions. We draw particular attention to the significance these estrogen receptors have for the onset and development of tumors outside the reproductive system. Knowledge of the receptor mechanisms of estrogenic action may enhance the diagnostic and therapeutic opportunities to treat a wide range of neoplastic lesions.

Changes in haemostasis during normal pregnancy.

OBJECTIVES: (1) To study the changes in the haemostatic variables during normal pregnancy, and (2) to compare them with the corresponding variables in a control group of nonpregnant women. SETTING: University Hospital. SUBJECTS: The study involves two groups of women: pregnant women (in 35th-40th gestational weeks (GW)) (N = 35) and a control group of nonpregnant women (N = 35). METHODS: We examined the global tests, the variables relating to coagulation and fibrinolysis and the group of natural inhibitors of coagulation, and compared them between the two groups. RESULTS: The pregnant women had statistically significantly higher values for: prothrombin time (PT) (P < 0.0001), thrombin time (TT) (P < 0.0001), fibrinogen (P < 0.0001), activity of factor VII (P < 0.0001), factor X (P < 0.0001) and alpha2-antiplasmin (P < 0.002), plasma concentration of D-dimer (plsDD) (P < 0.0001) and activity of heparin cofactor II (HCII) (P < 0.002). They had statistically significantly lower activity of protein C (PrC) (P < 0.0001) and of total protein S (TPrS) (P < 0.0001). CONCLUSION: During normal pregnancy the activation of coagulation is counterbalanced by the activation of fibrinolysis, which maintains the haemostatic balance.
