Insomnia in Pregnancy Is Associated With Depressive Symptoms and Eating at Night

STUDY OBJECTIVES

Deterioration in sleep quality seems to be a natural consequence of physical changes during pregnancy. It is still unclear if insomnia in pregnancy is associated with the same factors as chronic insomnia in the general population. The aim of this study was to explore the determinants of insomnia during pregnancy.

METHODS

The study included 266 women (mean age: 30.6 ± 5 years, weeks of pregnancy: 36 [interquartile range 32-38]) recruited at the Department of Gynecology and Obstetrics, Medical University of Warsaw. The assessment of variables was performed using the Athens Insomnia Scale (AIS), Beck Depression Inventory (BDI), Regestein Hyperarousal Scale (HS), Epworth Sleepiness Scale (ESS), General Practice Physical Activity Questionnaire, and a semi-structured interview about different sleep disorders.

RESULTS

Almost 40% of the women in our study received a diagnosis of insomnia based on AIS cutoff scores. The between-group analyses indicated that HS score, BDI score, eating at night, legs tingling, nightmares, snoring, and myoclonus differentiated the groups of individuals with insomnia from those without insomnia. Other variables were not significantly different between the groups. We divided individuals with insomnia in terms of insomnia duration: 49% developed insomnia at least 1 year before the study onset and 39.6% during pregnancy. For further analyses we used only the women in whom insomnia developed during pregnancy. Logistic regression confirmed that depressive symptoms (BDI) and eating at night were significant predictors of insomnia in pregnancy.

CONCLUSIONS

Depressive symptoms and night eating are key factors related to insomnia developed during pregnancy.

Potentialization of N-a-tosyl-L-phenylalanine chloromethyl ketone (TPCK) cytotoxic activity by 2-(1-adamantylamino)-6-methylpyridine (AdAMP) in human ovarian cancer cells

OBJECTIVES

TNF is one of the key cytokines involved in cancer development. TNF signaling can result in both stimulating and inhibitory signals that can result in opposite biological effects in cancerogenesis. 2-(1-adamantylamino)-6-methylpyridine (AdAMP) enhances TNF secretion whereas N-a-tosyl-L-phenylalanine chloromethyl ketone (TPCK) is a NF-κB inhibitor potentially stimulating proapoptotic TNF signals. The aim of the study was to assess the effect of TPCK in combination with AdAMP on human ovarian cells.

MATERIAL AND METHODS

CAOV-1 human ovarian cell line was incubated with TPCK and AdAMP for 24 hours. The cytotoxic effect was evaluated in a crystal violet assay. A monoclonal antibody against TNF, Infliximab, was added to examine the possible mechanism of interactions.

RESULTS

Depending on concentration, AdAMP potentialized cytotoxic activity of TPCK or had a synergistic effect with TPCK. Infliximab did not reverse cytotoxicity of AdAMP and TPCK and in some cytotoxic and non-cytotoxic concentrations even enhanced their cytotoxicity.

CONCLUSIONS

AdAMP and TPCK cytotoxicity seems to be dependent on TNF signaling, however, the exact mechanism of interactions remains unclear.

Emergency peripartum hysterectomy - a challenge or an obstetrical defeat?

OBJECTIVES

Peripartum hysterectomy remains an obstetric nightmare. Most obstetricians consider it a defeat. The aim of our study was to assess the prevalence, indications, procedures and complications of emergency peripartum hysterectomy (EPH) in the 2nd Department of Obstetrics & Gynecology, Medical University of Warsaw during a 7 year period (2007-2013).

METHODS

A retrospective evaluation of 21,144 deliveries was performed. We analyzed all cases of EPH, including the maternal characteristics, obstetrical history, course of pregnancy and delivery, type of surgery and complications.

RESULTS

Nineteen peripartum hysterectomies were performed between January 1, 2007 and October 30, 2013 (0.9/1000), including 16 EPH (0.76/1000). The rate of EPH was between 0.66 and 1.0 per 1000 deliveries. The majority of the patients were multiparous (79.0%), and EPH was performed after at least one cesarean section (75.0%). Fifteen women had a singleton pregnancy and one woman had a triplet pregnancy. The mean gestational age was 34.2 weeks. The delivery mode was cesarean section in 93.8% of the cases. The most common reason for peripartum hemorrhage and the indication for EPH was abnormal placentation (75.0%). All patients underwent a total hysterectomy, including 43.8% during the same operation and 50.0% during a reoperation. There was no maternal death. The serious maternal complication rates were relatively low in our study and included one case of cardiac arrest that required cardiopulmonary resuscitation and one case of sepsis with pulmonary embolism.

CONCLUSIONS

EPH is typically performed as a result of massive hemorrhage associated with abnormal placentation, and it should be treated as a challenging, life-saving procedure.

Evaluation of the amoxicillin concentrations in amniotic fluid, placenta, umbilical cord blood and maternal serum two hours after intravenous administration

OBJECTIVES

The aims of this study were to evaluate amoxicillin concentrations in amniotic fluid, placenta, umbilical cord blood and maternal blood two hours after intravenous administration to assess obstetric and non-obstetric factors that could have influences on the penetration of the antibiotic into the examined tissues and to analyze the sensitivity to amoxicillin of the most common pathogens isolated from the genital tract.

METHODS

A total of 35 full-term pregnant women who qualified for elective Caesarean delivery were included in the study. Amoxicillin at a dose of 1000 mg was administered prior to surgery. Amoxicillin levels were determined by diffusion microbial assay.

RESULTS

The drug concentration was highest in umbilical cord blood compared with amniotic fluid, maternal blood and placenta (4.20±1.06 µg/g versus 3.96±0.79 µg/g, 3.22±0.64 µg/g and 2.81±0.64 µg/g, respectively). Obstetric and non-obstetric factors had no influence on the amoxicillin concentration. The most common bacteria isolated from the genital tracts of pregnant women (Streptococcus agalactiae, Enterococcus faecalis, Escherichia coli) were sensitive to amoxicillin. The MIC for the sensitive strain of Streptococcus agalactiae was seen in the majority of tissues of all of the patients; however, the MICs for E. faecalis and E. coli were not observed in any compartment.

CONCLUSIONS

Amoxicillin proved to have good penetration into the fetal tissues and placenta after intravenous administration. The most common bacteria isolated from the genital tracts of pregnant women were sensitive to amoxicillin. Pregnancy complications were not found to have an influence on the amoxicillin concentrations in the examined tissues.

Premature ovarian insufficiency: the context of long-term effects

PURPOSE

Premature ovarian insufficiency (POI) is defined as the cessation of the ovarian function before the age of 40 years. POI aetiology may be related to iatrogenic or endogenous factors and in many cases remains unclear. The aim of this review was to characterize the long-term consequences of POI.

METHODS

The available literature regarding the long-term consequences of POI from MEDLINE has been reviewed.

RESULTS

Lack of ovarian steroids synthesis has serious consequences for women's health. The short-term effects are similar to spontaneous menopause and refer mainly to the climacteric syndrome. In a longer perspective, POI affects a variety of aspects. It obviously and drastically reduces the chances for spontaneous pregnancies. Oestrogen loss leads also to urogenital atrophy. The most common urogenital symptoms include vaginal dryness, vaginal irritation and itching. The urogenital atrophy and hypoestrogenism interferes also with sexual functioning. Patients with POI are threatened by a decrease in bone mineral density (BMD). POI women also experience psychological distress and some studies have shown an increased risk of neurodegenerating diseases. Overall, POI women have a shortened life expectancy, mainly due to cardiovascular disease. Some studies have reported a reduced risk of breast cancer in this group of patients.

CONCLUSIONS

In conclusion there are several well-characterized health risks in POI women. With every patient, an individualized approach is required to properly recognize and prevent these risks.

Results of optimal debulking surgery with bowel resection in patients with advanced ovarian cancer

BACKGROUND

The surgical treatment of patients with advanced-stage ovarian cancer is based on maximal cytoreduction with widening the debulking on the extra-ovarian tissues and infiltrated organs. The purpose of the study was to assess the outcome after optimal cytoreduction with partial bowel resection and to find the risk factors of relapse. Another goal was the quantitative and qualitative assessment of intra- and postoperative complications in the studied group.

METHODS

The analysis of debulking procedures with intestinal resection and postoperative period in 33 ovarian cancer patients, The International Federation of Gynecology and Obstetrics (FIGO) stages III and IV, was performed.

RESULTS

The optimal cytoreduction defined as less than 1.0 cm residual disease was achieved in all patients including the following: 26 patients (78.8%) with no macroscopic residual disease, 4 patients (12.1%) with the largest residual tumor less than 0.5, and 3 patients (9.1%) with 0.5 cm to less than 1.0 cm residual disease. The rectosigmoid resection was the most common surgical procedure (n = 27). The risk of relapse was significantly higher in subjects who had the macroscopic residual tumor left during the primary operation (57.1 vs. 11.5%, P = 0.035). A primary bowel tumor size was another predictor of relapse. The maximum tumor diameter was significantly larger (14.9 ± 6.7 cm vs. 10.3 ± 4.7 cm, P = 0.047) in patients who developed the relapse.

CONCLUSIONS

As presented in the article, our outcomes and other authors' observations indicate that debulking surgery with bowel resection in patients with advanced ovarian cancer brings good results. Complications connected with bowel surgery are to be accepted. The interesting thing is that a primary bowel tumor size was a predictor of relapse.

Pregnancy course in patients with intrahepatic cholestasis of pregnancy treated with very low doses of ursodeoxycholic acid

OBJECTIVE

Ursodeoxycholic acid (UDCA) has been proposed as the optimal pharmacological treatment for intrahepatic cholestasis of pregnancy (ICP). The lowest effective dosage of UDCA in women with ICP has not been established. The objective is to determine the risk of adverse pregnancy outcomes resulting from ICP and to measure changes in liver function parameters and pruritus severity in ICP patients treated with low doses of UDCA.

MATERIAL AND METHODS

ICP was diagnosed in 203 patients on the basis of pruritus and elevated liver biochemical parameters. Patients with total bile acids (TBA) ≥ 10 μmol/l (n = 157) received UDCA (300-450 mg/day; 4-6 mg/kg/day) until delivery. Maternal and fetal outcomes of women with ICP were compared with 100 patients without cholestasis. Patients with ICP were hospitalized for treatment and fetal surveillance.

RESULTS

There was no correlation between fetal and neonatal complication rates in ICP patients and biochemical markers of cholestasis. Significant declines in serum TBA (p = 0.003), bilirubin concentration (p = 0.026) and aminotransferase activity (p < 0.001) were observed during treatment with low doses of UDCA. Moreover, severity of pruritus was ameliorated during the 2 weeks of therapy (p = 0.037). A total of 17 patients (10.9%) did not respond to treatment.

CONCLUSIONS

UDCA at low doses improved biochemical markers and clinical symptoms in almost 90% of ICP patients.

Concentration of amoxicillin in maternal serum, cord blood, amniotic fluid and the placenta after vaginal administration

OBJECTIVE

The aim of this study was to assess the amoxicillin concentration in maternal serum, cord blood, amniotic fluid and the placenta, 2 h following vaginal administration and the factors influencing the drug level.

METHODS

Twenty-eight full-term pregnant women who qualified for elective cesarean delivery were included in the study. Vaginal suppositories containing 250 mg of amoxicillin were administered 2 h prior to the operation. Amoxicillin levels were determined using the diffusion microbial assay.

RESULTS

The amoxicillin level in amniotic fluid was significantly higher in comparison to that of maternal serum, cord blood or the placenta. Maternal age positively and gestational weight gain negatively correlated with the amoxicillin concentration in maternal serum. The maternal serum hemoglobin level and red blood cell count were positively correlated with amoxicillin concentration in the amniotic fluid. Neonatal birth weight was positively correlated with maternal serum and cord blood amoxicillin levels. Hypertensive women had significantly higher amoxicillin concentrations in amniotic fluid, and women with thrombocytopenia presented significantly higher cord blood amoxicillin concentrations.

CONCLUSIONS

Amoxicillin presented poor concentration in maternal-fetal compartments after vaginal administration, but the factors influencing the drug level in different compartments require further investigation.

Antenatal steroids: can we optimize the dose?

PURPOSE OF REVIEW

The beneficial effects of antenatal steroids in women at risk of preterm birth are evident. A dose of 24 mg appears sufficient, but there are insufficient data to recommend betamethasone or dexamethasone, a single steroid dose, the optimal interval between doses and repeated courses, the gestational age at which treatment is beneficial and the long-term effects of steroid treatment. This review addresses these aspects of antenatal steroid treatment.

RECENT FINDINGS

Although the 12-h and 24-h dosing intervals are equivalent with respect to prevention of respiratory distress syndrome, the former enables the completion of treatment in 50% more neonates delivered prematurely. Reducing the single steroid dose in patients at risk for premature birth reduces the associated maternal side effects. An inverse relationship has been demonstrated between the number of corticosteroid courses and foetal growth. The reduced size of exposed foetuses has been attributed to birth at earlier gestational ages and decreased foetal growth. Evidence suggests that antenatal exposure to synthetic glucocorticoids in term-born children has long-lasting effects, which may have important implications in the recommendation of steroids before elective caesarean at term.

SUMMARY

The short-term and long-term effects of the dosage regimen on the pregnant mother and foetus remain unclear.

Shoulder dystocia in diabetic and non-diabetic pregnancies

OBJECTIVES

Shoulder dystocia remains an obstetric emergency. Maternal diabetes is considered to be one of the major risk factors for shoulder dystocia. The aim of this study was to analyze antepartum and peripartum risk factors and complications of shoulder dystocia in diabetic and non-diabetic women.

DESIGN

We performed a retrospective analysis of 48 shoulder dystocia cases out of 28,485 vaginal deliveries of singleton, live-born infants over a 13 year period: 13 cases were diagnosed in diabetic women and 35 cases in non-diabetic women.

SETTING

The study was conducted in the 2nd Department of Obstetrics and Gynecology, Medical University of Warsaw, Poland, from January 2000 to December 2012.

RESULTS

Compared to non-diabetic women, diabetic patients had significantly higher pre-pregnancy body weight (83.4±23.8 kg vs. 62.5±10.9 kg, p=0.002), higher pre-pregnancy BMI (30.2±6.8 kg/m2 vs. 22.9±4.3 kg/m2, p=0.0003), and lower gestational weight gain (11.4±6.2 kg vs. 16.0±4.7 kg, p=0.01). Diabetic women with shoulder dystocia were more likely to deliver before completion of the 38th week of gestation (30.8% vs. 5.7%, p=0.02) and had a higher incidence of 1st and 2nd stage perineal tears compared with the non-diabetic group (23.1% vs. 0%, p=0.02). There were two cases of symphysis pubis dehiscence in non-diabetic women. Children of diabetic mothers had a significantly higher birth weight (4,425.4±561.6 g vs. 4,006.9±452.8 g, p=0.03). Children of diabetic mothers with dystocia were at significantly higher risk of peripartum injuries (92.3% vs. 45.7%). A significant difference was observed in the percentage of brachial plexus palsy (61.5% vs. 17.1%). Children of diabetic women experiencing shoulder dystocia were more frequently affected by Erb's brachial plexus palsy and respiratory disturbances. These children had an increased likelihood of birth weights above the 90th percentile (not necessarily reaching 4,000 g) compared to children born to non-diabetic mothers.

CONCLUSIONS

Shoulder dystocia in women with diabetes mellitus during pregnancy was associated with earlier gestational age of labor, and these women were more frequently overweight. The newborns of diabetic mothers after shoulder dystocia appeared to be at an increased risk for perinatal morbidity compared to the newborns of non-diabetic mothers experiencing this complication.

BMI of the firstborn offspring at age 12 reflects maternal LDL and HDL cholesterol levels at term pregnancy and postpartum

OBJECTIVE

The aim of this study was to assess the relationship between the body mass index (BMI) of the firstborn offspring at age 12 and maternal lipid levels at term and at 6 months postpartum.

DESIGN AND METHODS

The study included children born in the 2nd Department of Obstetrics and Gynecology of the Medical University of Warsaw between 1 November 1991 and 31 May 1993. The end point was BMI in the upper quartile - considered high BMI of the firstborn offspring at age 12.

RESULTS

The risk of high BMI in the offspring at age 12 significantly increased with an increase in the LDL-C level at term (OR = 2.41 per SD increase, 95% CI: 1.01-5.80; p < 0.049), a decrease in the HDL-C% at term (OR = 0.35 per SD increase, 95% CI: 0.14-0.84; p < 0.019) and a decrease in the HDL-C level at 6 months postpartum (OR = 0.25 per SD increase, 95% CI: 0.08-0.82; p < 0.022), regardless of maternal weight status before pregnancy and at 6 months postpartum, gestational weight gain, the offspring's gender and birth weight.

CONCLUSION

LDL and HDL cholesterol levels at term are markers of maternal adaptation to a first pregnancy and predict the future growth of firstborn offspring.

[Application of levonorgestrel-releasing intrauterine system in early pregnancy: a case report]

Intrauterine device is a popular cost-effective method of contraception known worldwide. It is extremely effective, with pregnancy rates comparable to tubal ligation (5-year cumulative rate varying from 0.5 to 1.1). LNG-IUS increases in popularity and may be used as the method of choice for adults because it offers non-contraceptive benefits: slight menstrual bleeding, decreased number of incidents of dysmenorrhea, and reduced pain associated with endometriosis. The levonorgestrel-releasing intrauterine system (LNG-IUS) provides a release rate of 20 microg/24 h of levonorgestrel. The hormone released from the intrauterine device causes some systemic changes, however local effects, such as glandular atrophy and stromal decidualization, in addition to foreign body reaction, are dominant. According to the Food and Drug Administration regulations, category X was assigned to LNG. The use of the product is contraindicated in women who are or may become pregnant. We report a case of a 30-year old woman who has already been pregnant before the insertion of a levonorgestrel -releasing intrauterine system (LNG-IUS). The patient was lactating after the previous pregnancy the first menstruation had not appeared yet. The patient planned to have the IUD inserted but she missed her appointed visits twice. The third visit took place 8 weeks postpartum. During that visit, the doctor asked her about the possibility of being pregnant, but the patient denied. The gynecologist inserted the intrauterine device and performed transvaginal ultrasound examination. The location of LNG-IUS was proper and there was no gestation sac in the uterine cavity. After the next six weeks, transvaginal ultrasonography and manual examination showed an intrauterine pregnancy at 8 weeks of gestation. The intrauterine device was not detectable in the uterine cavity by ultrasound, and the IUD strings were not visualized in the vagina. It was impossible to remove the device without causing miscarriage. Other risks during pregnancy were connected with potential masculinisation of the fetus by levonorgestrel, premature delivery and preterm rupture of the membranes. The pregnancy progressed normally and the delivery was uncomplicated. A female infant was born without congenital abnormalities. The pediatrician did not find any indices of infection. The IUD was found in fetal membranes. The postpartum recovery was uneventful. This case report demonstrates that a healthy infant can be delivered at term with an IUS in situ, probably without causing any abnormalities. Due to that fact that adverse effects of fetal exposure to the LNG-IUS have not been yet established, the exclusion of pregnancy before IUD insertion is strictly indicated.

Dosage regimen of antenatal steroids prior to preterm delivery and effects on maternal and neonatal outcomes

OBJECTIVE

The objective of this study was to compare the effects of two betamethasone dosage regimens on selected parameters in mothers and on the status of the preterm newborn.

METHODS

The analysis included 121 patients who gave birth by gestational week 35 and within 7 days after the completion of a full course of steroid treatment (24 mg). The study group consisted of 45 patients receiving six 4-mg doses of betamethasone every 8 h. The control group consisted of 76 patients receiving two 12-mg doses of betamethasone separated by 24 h.

RESULTS

After treatment, a significant increase in the leukocyte count was observed in the control group. Significant reductions in the erythrocyte counts, hemoglobin levels and hematocrit after treatment were also found in the control group. The post-natal status of newborns did not differ significantly between groups. The betamethasone dosage regimen used did not affect the incidence of moderate and severe respiratory disorders, intraventricular hemorrhage (IVH), necrotizing enterocolitis (NEC), retinopathy (ROP), infection, hyperbilirubinemia or anemia in neonates. Mild respiratory disorders were slightly more common in the study group.

CONCLUSION

A reduction in the single steroid dose administered to patients at risk of premature birth may reduce maternal side-effects.

[Recommendations of Polish Gynecological Society concerning perinatal care in obese pregnant women]

Maternal obesity (defined as prepregnancy maternal BMI> or = 30 kg/m2) is a risk factor strongly associated with serious perinatal complications and its prevalence has increased rapidly in a general population during the last decades. Therefore, following international approach to regulate perinatal care in this population, Group of Experts of Polish Gynecological Society developed these new guidelines concerning perinatal care in obese pregnant women, including women after bariatric surgery. The recommendations cover detailed information on specific needs and risks associated with obesity in women of reproductive age, pregnancy planning, antenatal care, screening, prophylaxis and treatment for other pregnancy complications characteristic for maternal obesity fetal surveillance, intrapartum care and post-partum follow-up. Pregnancy planning in these patients should involve dietary recommendations aiming at well balanced diet and daily caloric uptake below 2000 kcal and modest but regular physical activity with sessions every two days starting from 15 min and increased gradually to 40 min. Laboratory work-up should include tests recommended in general population plus fasting glycemia and oral glucose tolerance if necessary thyroid function, lipidprofile, blood pressure and ECG. Patients after bariatric surgery should allow at least one year before they conceive and have their diet fortified with iron, folic acid, calcium and vit. B12. Antenatal care should include monitoring body weight gain with a target increase in body weight less than 7 kg, thromboprophylaxis, strict monitoring of blood pressure and diagnostic for gestational diabetes in early pregnancy. Fetal ultrasonic scans should be arranged following protocols recommended by US section of Polish Gynaecological Society with additional scan assessing fetal growth performed within 7 days before delivery and aiming at assessing a risk for shoulder dystocia in a patient. Intrapartum care should be delivered in referral centers where fetal and maternal intrapartum complications can be addressed, preferably equipped with a proper medical equipment necessary to deal safely with extremely heavy individuals. Medical staff taking intrapartum care for obese parturient should be also aware of reduced reliability of methods used for intrapartum fetal surveillance, increased risk for intrapartum fetal death, maternal injuries, postpartum haemorrhage, shoulder dystocia, thrombophlebitis and infection. Pediatrician should be also available due to increased neonatal morbidity mainly due to meconium aspiration syndrome, hypoglycemia, and respiratory distress syndrome. In puerperium, medical staff should be prepared to deal with breastfeeding disturbances and increased maternal mortality.

[Clinical practice guidelines of the Team of Experts of the Polish Gynecological Society: management of the intrahepatic cholestasis of pregnancy]

Intrahepatic Cholestasis of Pregnancy (ICP) constitutes the most common, reversible liver disease closely connected with pregnancy and spontaneously resolving in puerperium. ICP usually reoccurs in consecutive pregnancies (45-90%), often in a more intensified form. Many compounds (hormones, cytokines, medicines, endotoxins) can impair transport in the hepatocyte, disturb the intracellular transport and increase the permeability of the intercellular connections. As a result, the elements of bile may appear in the peripheral blood. Gestational cholestasis constitutes a classic example of intrahepatic cholestasis. The etiology of ICP is multifactorial with hormonal, genetic and environmental factors participating in the process. The diagnosis is based on the presence of pruritus, elevated values of bile acids in the blood serum and of aminotransferases (aspartic, aminopropionic and gamma-glutamylotranspeptydase (AspAt, AlAt, GGTP)), as well as spontaneous remission in the second or third week after childbirth, of lack of other illnesses causing pruritus and icterus. Clinical and biochemical symptoms of ICP include: pruritus without skin rash (usually after 30 weeks of gestation), mild icterus, steatorrhea etc. Abnormalities in the laboratory tests of the LFT (liver function tests) encompass: an increase in the serum concentration of fatty acids (BA) which can be the first and only laboratory abnormality. Concentrations surpassing 10 micromol/l are considered to be abnormal. Concentration of BA higher than 40 micromol/l allows to recognize a case of severe ICP, connected with the risk of premature delivery presence of the meconium liquor, surgical means of delivery and low APGAR score of the newborn (< 7 pt). In about 80% of pregnant women with ICP, the BA concentration ranges between 10-40 micromol/l, but perinatal results are comparable with uncomplicated pregnancies. Some authors are of the opinion that abnormal AlAt value is the most sensitive test, other authors consider the abnormal values of alkaline phosphatase and bilirubin to be the most pathognomonic factors. Other abnormal tests include: higher activity of alpha-hydroxybutyric dehydrogenase correlated with an increase of the alkaline phosphatase and bilirubin; mild metabolic acidosis; dyslipidemia with elevated concentrations of the total lipids, total cholesterol and free LDL cholesterol and apolipoprotein; abnormal glucose tolerance test. ICP constitutes a medical problem that carries a considerable risk for the fetus, resulting from an increased flow of bile acids to the fetal blood circulation (elevated level in the amniotic fluid, in the umbilical blood serum and meconium). The risk of adverse effects for the fetus correlates with the rise of BA concentration in maternal blood serum. Cholestasis increases the risk of premature labor, presence of meconium in the amniotic fluid, fetal bradycardia, intrauterine asphyxia and stillbirth, particularly when the concentration of serum bile acids on an empty stomach is above 40 micromol/l. However, maternal clinical signs and symptoms do not correlate with the fetal outcome. Aspiration of bile acids or their accumulation in the fetal blood circulation are responsible for the increased frequency of RDS appearing in ICP. The aim of the obstetric management of ICP is to reduce maternal symptoms and biochemical disorders and to minimize the risk of premature delivery fetal distress and sudden death. ICP management should include: bed regime, light, low-fat diet, no stress, upper abdomen ultrasound examination, LFT tests and thrombotic tests once a week, monitoring of the fetal well-being with the available biophysical methods, pharmacotherapy and therapeutic termination of pregnancy in case of serious illness and/or the fetal distress. Ursodeoxycholic acid (UDCA) is the basis of the pharmacological treatment of pregnant women and currently constitutes the most promising treatment option of ICP. UDCA is administered orally in the dosage of 10-16 mg/kg/24, what in practice means 250-300 mg/2-3 times a day.

Therapeutic challenges and management of heart failure during pregnancy (part 2)

A particularly dangerous condition in pregnant women is already dilated left ventricle with severe functional impairment. Taking as an example the case of woman with dilated cardiomyopathy (DCM) first diagnosed in 17th week of pregnancy, the paper discusses diagnostic, therapeutic challenges and management of heart failure during pregnancy. Repeat measurements of brain natiuretic peptide levels should be helpful in diagnosing heart failure. To distinguish DCM from peripartum cardiomyopathy the time of manifestation should be considered. The risk of serious events is associated with NYHA class and impairment of left ventricular ejection fraction. Angiotensin-converting enzyme inhibitors (ACE-I) and angiotensin-II receptor blockers are contraindicated in pregnancy because of fetal toxicity. The incidence of sight effects is associated with time of administration of ACE-I and duration of treatment. Possible sight effects of drugs in fetus should be monitored (mainly ultrasonographically). ICD can be implanted during pregnancy if indicated. To assess the time and mode of delivery, a multidisciplinary team of different specialists is required. Subsequent pregnancy is contraindicated in a patient with DCM and low ejection fraction of left ventricle.

Risk factors of abnormal carbohydrate metabolism after pregnancy complicated by gestational diabetes mellitus

OBJECTIVE

In gestational diabetes mellitus (GDM) abnormal glucose metabolism normalizes soon after delivery. However, the history of GDM predisposes to carbohydrate intolerance in the future. The aim of the study was to explore risk factors and to evaluate risk of glucose intolerance and diabetes mellitus in women with a history of GDM.

METHODS

155 patients entered this case-control study. Participants fulfilled the inclusion criteria: a history of GDM, perinatal care in the study center. Medical and family history and laboratory findings were analyzed. Oral glucose tolerance test (OGTT) was performed.

RESULTS

18.1% of patients presented impaired fasting glucose during the study, 20% presented impaired glucose tolerance and 23.2% presented diabetes mellitus. Gestational age at diagnosis of GDM, the results of OGTT during pregnancy, serum HbA1c concentration at 2nd and 3rd trimester, serum fructosamine concentration, symptoms of diabetic fetopathy in the neonate, the need for insulin therapy after delivery, maternal age at diagnosis of GDM and maternal body mass index before pregnancy were the significant risk factors of impaired glucose tolerance or diabetes in the future.

CONCLUSION

GDM increases the risk of diabetes mellitus. Several risk factors of impaired carbohydrate metabolism can be distinguished in patients with a history of GDM.

Therapeutic challenges and management of heart failure during pregnancy (part I)

Therapeutic management in pregnant patients with heart failure still remains a challenge, even though in most pregnant women with cardiac diseases an outcome is good. A 32-year-old woman, 17 weeks pregnant, was admitted to hospital with heart failure (HF) NYHA class III/IV. Echocardiography revealed enlarged LV, LVEF 13%, significant mitral insufficiency and pulmonary hypertension. The patient wished to continue the pregnancy. In a life-threatening condition, metoprolol, enalapril, spironolactone (for 5 days), furosemide, and digitalis were administered. Enalapril was continued for 42 days. Then the patient was switched to a dihydralazine and isosorbide mononitrate regimen. The fetus was controlled ultrasonographically. In the 19th week of pregnancy, the patient's condition improved (NYHA class II, LVEF 23%). The patient experienced 2 more episodes of HF exacerbation. In the 26th week of pregnancy, in a primary prevention of sudden cardiac death and because of 2nd-degree AV block, an ICD was implanted. In the 32nd week of pregnancy a cesarean section was performed. A male infant was delivered. The patient made a good recovery and was discharged on the 7th postoperative day. The newborn was discharged after 4 weeks, in good general condition. At 1-year follow-up the patient presented NYHA class II.<br />

Historic discovery of natural thermodynamic cause of cancer

The essence of life is best manifested in cell, which, when brought to the edge of its existence in the actual environment may and sometimes must self-organise into an entirely different cell (neoplasm), but it must enhance dissipation of matter and energy in its closest environment. This phenomenon has been described before as self-organisation of dissipative structures in physics, chemistry and even sociology. Each neoplastic cell is such a dissipative system - with its clonal growth, the cell causes increasing disorganisation of the body, in consequence leading to neoplastic disease. The only adequate cause of formation of neoplasms is an internal dissipathogenic cellular state, which is clinically identify as preneoplastic ones at the level of morphology or molecular biology but also biophysics. Two general directions for therapy of neoplastic diseases arise from the thermodynamic essence of neogenesis: the direct one - targeting neoplasms, and the indirect one - leading to normalisation or sufficient alteration of their environment. The greatest disappointment in the fight against neoplasm was the discovery of its thermodynamic cause in a natural self-organisation of biological dissipative structures. It is this dissipation that causes the signs and symptoms of neoplastic diseases ending with destruction of the body if the treatment comes too late and/or is insufficient, limited only to removal of neoplastic lesions without the always necessary elimination and/or prevention of preneoplastic (dissipathogenic) states.
