Pregnancy Complications: Conditions or pathological processes associated with pregnancy. They can occur during or after pregnancy, and range from minor discomforts to serious diseases that require medical interventions. They include diseases in pregnant females, and pregnancies in females with diseases.Pregnancy: The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.Pregnancy Outcome: Results of conception and ensuing pregnancy, including LIVE BIRTH; STILLBIRTH; SPONTANEOUS ABORTION; INDUCED ABORTION. The outcome may follow natural or artificial insemination or any of the various ASSISTED REPRODUCTIVE TECHNIQUES, such as EMBRYO TRANSFER or FERTILIZATION IN VITRO.Pre-Eclampsia: A complication of PREGNANCY, characterized by a complex of symptoms including maternal HYPERTENSION and PROTEINURIA with or without pathological EDEMA. Symptoms may range between mild and severe. Pre-eclampsia usually occurs after the 20th week of gestation, but may develop before this time in the presence of trophoblastic disease.Hypertension, Pregnancy-Induced: A condition in pregnant women with elevated systolic (>140 mm Hg) and diastolic (>90 mm Hg) blood pressure on at least two occasions 6 h apart. HYPERTENSION complicates 8-10% of all pregnancies, generally after 20 weeks of gestation. Gestational hypertension can be divided into several broad categories according to the complexity and associated symptoms, such as EDEMA; PROTEINURIA; SEIZURES; abnormalities in BLOOD COAGULATION and liver functions.Pregnancy Complications, Cardiovascular: The co-occurrence of pregnancy and a cardiovascular disease. The disease may precede or follow FERTILIZATION and it may or may not have a deleterious effect on the pregnant woman or FETUS.Pregnancy Complications, Hematologic: The co-occurrence of pregnancy and a blood disease (HEMATOLOGIC DISEASES) which involves BLOOD CELLS or COAGULATION FACTORS. The hematologic disease may precede or follow FERTILIZATION and it may or may not have a deleterious effect on the pregnant woman or FETUS.Female Urogenital Diseases and Pregnancy Complications: Pathological processes of the female URINARY TRACT, the reproductive system (GENITALIA, FEMALE), and disorders related to PREGNANCY.Pregnancy Trimester, First: The beginning third of a human PREGNANCY, from the first day of the last normal menstrual period (MENSTRUATION) through the completion of 14 weeks (98 days) of gestation.Pregnancy, Ectopic: A potentially life-threatening condition in which EMBRYO IMPLANTATION occurs outside the cavity of the UTERUS.

During pregnancy, the thickest part of the decidua forms the maternal portion of the PLACENTA, thus named decidua placentalis. The thin portion of the decidua covering the rest of the embryo is the decidua capsularis.Odds Ratio: The ratio of two odds. The exposure-odds ratio for case control data is the ratio of the odds in favor of exposure among cases to the odds in favor of exposure among noncases.

It is usually estimated by various formulas based on measurements made during PRENATAL ULTRASONOGRAPHY.Prognosis: A prediction of the probable outcome of a disease based on a individual's condition and the usual course of the disease as seen in similar situations.Amniocentesis: Percutaneous transabdominal puncture of the uterus during pregnancy to obtain amniotic fluid. It is commonly used for fetal karyotype determination in order to diagnose abnormal fetal conditions.Corpus Luteum: The yellow body derived from the ruptured OVARIAN FOLLICLE after OVULATION. The process of corpus luteum formation, LUTEINIZATION, is regulated by LUTEINIZING HORMONE.Embryonic and Fetal Development: Morphological and physiological development of EMBRYOS or FETUSES.Surgical Procedures, Minimally Invasive: Procedures that avoid use of open, invasive surgery in favor of closed or local surgery. These generally involve use of laparoscopic devices and remote-control manipulation of instruments with indirect observation of the surgical field through an endoscope or similar device.Cross-Sectional Studies: Studies in which the presence or absence of disease or other health-related variables are determined in each member of the study population or in a representative sample at one particular time. This contrasts with LONGITUDINAL STUDIES which are followed over a period of time.Laparotomy: Incision into the side of the abdomen between the ribs and pelvis.Liver Transplantation: The transference of a part of or an entire liver from one human or animal to another.Family Planning Services: Health care programs or services designed to assist individuals in the planning of family size. Various methods of CONTRACEPTION can be used to control the number and timing of childbirths.Fetal Blood: Blood of the fetus. Exchange of nutrients and waste between the fetal and maternal blood occurs via the PLACENTA. The cord blood is blood contained in the umbilical vessels (UMBILICAL CORD) at the time of delivery.Fistula: Abnormal communication most commonly seen between two internal organs, or between an internal organ and the surface of the body.Cryopreservation: Preservation of cells, tissues, organs, or embryos by freezing. In histological preparations, cryopreservation or cryofixation is used to maintain the existing form, structure, and chemical composition of all the constituent elements of the specimens.Smoking: Inhaling and exhaling the smoke of burning TOBACCO.

*  Scientists Identify Genetic Susceptibility to Pregnancy Complication - Scientific American
Up to 20 percent of pregnant women may experience preeclampsia, a dangerous precursor to eclampsia, which brings on fatal seizures. Because the most common treatment for preeclampsia is early delivery--which can put both mother and baby at risk--researchers are eager to discover the cause of the disease and develop new treatments. To that end, findings published online this week by the journal Nature Genetics, could help. Scientists report the discovery of a gene associated with susceptibility to preeclampsia. Marie van Dijk of VU University Medical Center in Amsterdam and her colleagues studied 24 families in which two or more sisters had suffered from preeclampsia. After performing a genetic analysis, the researchers determined that mothers-to-be afflicted with the condition exhibited the same variant of a gene called STOX1. Each woman had inherited the variant from her mother and only this maternal copy was expressed in the placenta when preeclampsia arose. The authors suggest that a ...

Prenatal nutrition: Nutrition and weight management before and during :pregnancy has a profound effect on the development of infants. This is a rather critical time for healthy fetal development as infants rely heavily on maternal stores and nutrient for optimal growth and health outcome later in life.Gestational hypertensionGestational thrombocytopeniaOvarian pregnancyPlacental abruptionPlacenta: The placenta (also known as afterbirth) is an organ that connects the developing fetus to the uterine wall to allow nutrient uptake, waste elimination, and gas exchange via the mother's blood supply, fight against internal infection and produce hormones to support pregnancy. The placenta provides oxygen and nutrients to growing babies and removes waste products from the baby's blood.Yeidckol Polevnsky Gurwitz: Yeidckol Polevnsky Gurwitz (born January 25, 1958 in Mexico City as Citlali Ibáñez Camacho) is a Mexican entrepreneur and current Senator. In 2005 she was nominated by the Party of the Democratic Revolution (PRD) as the State of México governor candidate.Villitis of unknown etiology: Villitis of unknown etiology, abbreviated VUE, is an inflammatory process that involves the chorionic villi (villitis) whose cause (etiology) is not known. VUE is associated with recurrent miscarriage and intrauterine growth restriction, and recurs in subsequent pregnancies.EclampsiaGestational age: Gestational age (or menstrual age) is a measure of the age of a pregnancy where the origin is the woman's last normal menstrual period (LMP), or the corresponding age as estimated by other methods. Such methods include adding 14 days to a known duration since fertilization (as is possible in in vitro fertilization), or by obstetric ultrasonography.Trophoblast: Trophoblasts (from Greek trephein: to feed, and blastos: germinator) are cells forming the outer layer of a blastocyst, which provide nutrients to the embryo and develop into a large part of the placenta. They are formed during the first stage of pregnancy and are the first cells to differentiate from the fertilized egg.International Association of Plastics DistributorsNational Birth Defects Prevention Network: The National Birth Defects Prevention Network (NBDPN) was founded in 1997. It is a 501(c)3 not-for-profit volunteer organization whose members are involved in birth defects surveillance, prevention and research.Pre-conception counseling: Pre-conception counseling (also called pre-conceptual counseling) is a meeting with a health-care professional (generally a physician) by a woman before attempting to become pregnant. It generally includes a pre-conception risk assessment for any potential complications of pregnancy as well as modifications of risk factors, such as increasing folic acid intake to reduce the risk of neural tube defects and counseling on smoking cessation, alcohol reduction, and medications that may compromise fetal development.Lower segment Caesarean section: A lower (uterine) segment Caesarean section (LSCS) is the most commonly used type of Caesarean section used today. It includes a transverse cut just above the edge of the bladder and results in less blood loss and is easier to repair than other types of Caesarean sections.Obstetric labor complicationGlobal Alliance to Prevent Prematurity and StillbirthUterus transplantation: The uterine transplant is the surgical procedure whereby a healthy uterus is transplanted into a female organism of which the uterus is absent or diseased. As part of normal mammalian sexual reproduction, a diseased or absent uterus does not allow normal embryonic implantation, effectively rendering the female infertile.Birth weight: Birth weight is the body weight of a baby at its birth.Definitions from Georgia Department of Public Health.QRISK: QRISK2 (the most recent version of QRISK) is a prediction algorithm for cardiovascular disease (CVD) that uses traditional risk factors (age, systolic blood pressure, smoking status and ratio of total serum cholesterol to high-density lipoprotein cholesterol) together with body mass index, ethnicity, measures of deprivation, family history, chronic kidney disease, rheumatoid arthritis, atrial fibrillation, diabetes mellitus, and antihypertensive treatment.Pregnancy rate: Pregnancy rate is the success rate for getting pregnant. It is the percentage of all attempts that leads to pregnancy, with attempts generally referring to menstrual cycles where insemination or any artificial equivalent is used, which may be simple artificial insemination (AI) or AI with additional in vitro fertilization.Placental insufficiencyPregnancy test: A pregnancy test attempts to determine whether a woman is pregnant. Markers that indicate pregnancy are found in urine and blood, and pregnancy tests require sampling one of these substances.Transplacental carcinogenesis: Transplacental carcinogenesis is a series of genotypic and/or phenotypic changes in the cells of a fetus due to in utero exposure to carcinogens. Specifically, these changes are identified as malignant by virtue of their metastatic potential.Interstitial pregnancyAntiphospholipid syndrome: (ILDS D68.810)Low birth-weight paradox: The low birth-weight paradox is an apparently paradoxical observation relating to the birth weights and mortality rate of children born to tobacco smoking mothers. Low birth-weight children born to smoking mothers have a lower infant mortality rate than the low birth weight children of non-smokers.Premature rupture of membranesNatural cycle in vitro fertilization: Natural Cycle IVF is in vitro fertilisation (IVF) using either of the following procedures:Teenage Mother (film): Teenage Mother (a.k.Decidual reaction: The decidual reaction is the changes in the endometrium of the uterus that prepare it for implantation of an embryo. These changes are observed in each menstrual cycle and enhanced after implantation.ThrombophiliaUnintended pregnancy: Unintended pregnancies are pregnancies that are mistimed, unplanned or unwanted at the time of conception. Unintended pregnancy mainly results from engaging in vaginal sexual activity without the use of contraception, or due to incorrect use of a contraceptive method, but may also arise from the failure of the contraception method when used correctly to prevent pregnancy.Global Risks Report: The Global Risks Report is an annual study published by the World Economic Forum ahead of the Forum’s Annual Meeting in Davos, Switzerland. Based on the work of the Global Risk Network, the report describes changes occurring in the global risks landscape from year to year and identifies the global risks that could play a critical role in the upcoming year.Hospital of Southern Norway: [[Sørlandet Hospital Arendal, seen from the north.|thumb|200px]]Incidence (epidemiology): Incidence is a measure of the probability of occurrence of a given medical condition in a population within a specified period of time. Although sometimes loosely expressed simply as the number of new cases during some time period, it is better expressed as a proportion or a rate with a denominator.Medical abortion: A medical abortion is a type of non-surgical abortion in which abortifacient pharmaceutical drugs are used to induce abortion. An oral preparation for medical abortion is commonly referred to as an abortion pill.List of Parliamentary constituencies in Kent: The ceremonial county of Kent,Temporal analysis of products: Temporal Analysis of Products (TAP), (TAP-2), (TAP-3) is an experimental technique for studyingNested case-control study: A nested case control (NCC) study is a variation of a case-control study in which only a subset of controls from the cohort are compared to the incident cases. In a case-cohort study, all incident cases in the cohort are compared to a random subset of participants who do not develop the disease of interest.Closed-ended question: A closed-ended question is a question format that limits respondents with a list of answer choices from which they must choose to answer the question.Dillman D.Abdominal pregnancyEmbryo transfer: Embryo transfer refers to a step in the process of assisted reproduction in which embryos are placed into the uterus of a female with the intent to establish a pregnancy. This technique (which is often used in connection with in vitro fertilization (IVF)), may be used in humans or in animals, in which situations the goals may vary.

(1/5172) Biochemical indices of osteomalacia in pregnant Asian immigrants in Britain.

Serum calcium, phosphate and alkaline phosphatase, and urinary calcium excretion were examined during the second trimester of uncomplicated normal pregnancy in Asian immigrants to Britain and in local Caucasians. The mean serum calcium was significantly lower in Asians than in Caucasians, and the mean serum alkaline phosphatase was significantly higher in Asians. The geometric mean of the urinary calcium excretion was highly significantly lower in Asians than in Caucasians. The variances of the serum calcium, serum alkaline phosphatase, and urine calcium excretion did not differ significantly in the two populations. This indicates that there is a shift in values of immigrant Asians as a group compared with Caucasians. A comparison with figures obtained on normal nonpregnant persons of both suggests that the shift is not an inherent feature of the Asian population.  (+info)

(2/5172) Home care of high risk pregnant women by advanced practice nurses: nurse time consumed.

This study examined the time spent by advanced practice nurses (APNs) in providing prenatal care to women with high risk pregnancies. The results indicate that the overall mean APN time spent in providing prenatal care was 51.3 hours per woman. The greatest amount of time was spent in the clinic and women with pregestational diabetes consumed the most APN time and required the most contacts. Historically, home care services have been measured by number of visits or contacts. This study assists home care nurses and administrators to consider additional measurements including time spent.  (+info)

(3/5172) Effect of vitamin A and beta carotene supplementation on women's health.

 (+info)

(4/5172) Double blind, cluster randomised trial of low dose supplementation with vitamin A or beta carotene on mortality related to pregnancy in Nepal. The NNIPS-2 Study Group.

OBJECTIVE: To assess the impact on mortality related to pregnancy of supplementing women of reproductive age each week with a recommended dietary allowance of vitamin A, either preformed or as beta carotene. DESIGN: Double blind, cluster randomised, placebo controlled field trial. SETTING: Rural southeast central plains of Nepal (Sarlahi district). SUBJECTS: 44 646 married women, of whom 20 119 became pregnant 22 189 times. INTERVENTION: 270 wards randomised to 3 groups of 90 each for women to receive weekly a single oral supplement of placebo, vitamin A (7000 micrograms retinol equivalents) or beta carotene (42 mg, or 7000 micrograms retinol equivalents) for over 31/2 years. MAIN OUTCOME MEASURES: All cause mortality in women during pregnancy up to 12 weeks post partum (pregnancy related mortality) and mortality during pregnancy to 6 weeks postpartum, excluding deaths apparently related to injury (maternal mortality). RESULTS: Mortality related to pregnancy in the placebo, vitamin A, and beta carotene groups was 704, 426, and 361 deaths per 100 000 pregnancies, yielding relative risks (95% confidence intervals) of 0. 60 (0.37 to 0.97) and 0.51 (0.30 to 0.86). This represented reductions of 40% (P<0.04) and 49% (P<0.01) among those who received vitamin A and beta carotene. Combined, vitamin A or beta carotene lowered mortality by 44% (0.56 (0.37 to 0.84), P<0.005) and reduced the maternal mortality ratio from 645 to 385 deaths per 100 000 live births, or by 40% (P<0.02). Differences in cause of death could not be reliably distinguished between supplemented and placebo groups. CONCLUSION: Supplementation of women with either vitamin A or beta carotene at recommended dietary amounts during childbearing years can lower mortality related to pregnancy in rural, undernourished populations of south Asia.  (+info)

(5/5172) Effects of twinning on gestation length, retained placenta, and dystocia.

Constraints to maximal productivity from twinning in beef cattle include increased incidence of dystocia and retained placenta, longer postpartum interval, and lower conception rate. Incidence and cause(s) of the shorter gestation length and of the increased retained placenta and dystocia associated with twinning were evaluated for 3,370 single and 1,014 twin births produced in a population of cattle selected for natural twin births. Gestation length was shorter for twin than for single pregnancies (275.6 vs. 281.3 d, P<.01) and likely contributed to the higher incidence of retained placenta associated with twin births (27.9 vs. 1.9%; P<.01). Incidence of retained placenta was also higher in the spring (March-April) than in the fall (August-September) calving season (18.3 vs. 11.4%; P<.01). The higher incidence of dystocia with twins than with singles (46.9 vs. 20.6%, P<.01) was primarily due to abnormal presentation (37.0 vs. 4.5%, respectively) of one or both twin calves at parturition. First- (40.5%) and second- (22.7%) parity dams with a single birth had more (P<.01) dystocia than older dams (13.4%), whereas dystocia was not affected (P>.10) by parity with twin births. Because of the shorter gestation length and the increased incidence of retained placenta and(or) dystocia, achievement of increased productivity with twinning in cattle necessitates intensive management of twin-producing dams and their calves during the calving season. Management of the increased dystocia can be facilitated by preparturient diagnosis of twin pregnancies, enabling timely administration of obstetrical assistance to facilitate delivery of twin calves and to increase their neonatal survival.  (+info)

(6/5172) Liver disease in pregnancy.

Acute viral hepatitis is the most common cause of jaundice in pregnancy. The course of acute hepatitis is unaffected by pregnancy, except in patients with hepatitis E and disseminated herpes simplex infections, in which maternal and fetal mortality rates are significantly increased. Chronic hepatitis B or C infections may be transmitted to neonates; however, hepatitis B virus transmission is effectively prevented with perinatal hepatitis B vaccination and prophylaxis with hepatitis B immune globulin. Cholelithiasis occurs in 6 percent of pregnancies; complications can safely be treated with surgery. Women with chronic liver disease or cirrhosis exhibit a higher risk of fetal loss during pregnancy. Preeclampsia is associated with HELLP (hemolysis, elevated liver enzymes and low platelet count) syndrome, acute fatty liver of pregnancy, and hepatic infarction and rupture. These rare diseases result in increased maternal and fetal mortality. Treatment involves prompt delivery, whereupon the liver disease quickly reverses. Therapy with penicillamine, trientine, prednisone or azathioprine can be safely continued during pregnancy.  (+info)

(7/5172) Time-dependent and tissue-specific effects of circulating glucose on fetal ovine glucose transporters.

To determine the cellular adaptations to fetal hyperglycemia and hypoglycemia, we examined the time-dependent effects on basal (GLUT-1 and GLUT-3) and insulin-responsive (GLUT-4) glucose transporter proteins by quantitative Western blot analysis in fetal ovine insulin-insensitive (brain and liver) and insulin-sensitive (myocardium, skeletal muscle, and adipose) tissues. Maternal glucose infusions causing fetal hyperglycemia resulted in a transient 30% increase in brain GLUT-1 but not GLUT-3 levels and a decline in liver and adipose GLUT-1 and myocardial and skeletal muscle GLUT-1 and GLUT-4 levels compared with gestational age-matched controls. Maternal insulin infusions leading to fetal hypoglycemia caused a decline in brain GLUT-3, an increase in brain GLUT-1, and a subsequent decline in liver GLUT-1, with no significant change in insulin-sensitive myocardium, skeletal muscle, and adipose tissue GLUT-1 or GLUT-4 concentrations, compared with gestational age-matched sham controls. We conclude that fetal glucose transporters are subject to a time-dependent and tissue- and isoform-specific differential regulation in response to altered circulating glucose and/or insulin concentrations. These cellular adaptations in GLUT-1 (and GLUT-3) are geared toward protecting the conceptus from perturbations in substrate availability, and the adaptations in GLUT-4 are geared toward development of fetal insulin resistance.  (+info)

(8/5172) Desmoid tumour. The risk of recurrent or new disease with subsequent pregnancy: a case report.

Desmoid tumours are rare, benign tumours arising from fibrous tissue in muscle fascia or aponeurosis. They are most common in women of child-bearing age and most often appear during or after pregnancy in this age group. The recommended treatment is wide surgical excision, if possible, but unresectable tumours may be treated with radiotherapy, anticancer drugs, nonsteroidal anti-inflammatory agents or antiestrogenic compounds. The recurrence rate is high and seems to be related to the achievement of resection margins free of tumour. The literature is not specific about how to counsel women who have had a desmoid tumour and subsequently wish to have a child. Patients should be advised that these tumours may be estrogen sensitive but subsequent pregnancy is not necessarily a risk factor for recurrence or development of new disease.  (+info)
