A parameter usually used in PRENATAL ULTRASONOGRAPHY to measure the length of the uterine neck (CERVIX UTERI). Cervical length or its shortening is used to identify and prevent early cervical opening and PRETERM BIRTH.
The neck portion of the UTERUS between the lower isthmus and the VAGINA forming the cervical canal.
Onset of OBSTETRIC LABOR before term (TERM BIRTH) but usually after the FETUS has become viable. In humans, it occurs sometime during the 29th through 38th week of PREGNANCY. TOCOLYSIS inhibits premature labor and can prevent the BIRTH of premature infants (INFANT, PREMATURE).
A change in the CERVIX UTERI with respect to its readiness to relax. The cervix normally becomes softer, more flexible, more distensible, and shorter in the final weeks of PREGNANCY. These cervical changes can also be chemically induced (LABOR, INDUCED).
The middle third of a human PREGNANCY, from the beginning of the 15th through the 28th completed week (99 to 196 days) of gestation.
CHILDBIRTH before 37 weeks of PREGNANCY (259 days from the first day of the mother's last menstrual period, or 245 days after FERTILIZATION).
The last third of a human PREGNANCY, from the beginning of the 29th through the 42nd completed week (197 to 294 days) of gestation.
The visualization of tissues during pregnancy through recording of the echoes of ultrasonic waves directed into the body. The procedure may be applied with reference to the mother or the fetus and with reference to organs or the detection of maternal or fetal disease.
The age of the conceptus, beginning from the time of FERTILIZATION. In clinical obstetrics, the gestational age is often estimated as the time from the last day of the last MENSTRUATION which is about 2 weeks before OVULATION and fertilization.
The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH.
Two individuals derived from two FETUSES that were fertilized at or about the same time, developed in the UTERUS simultaneously, and born to the same mother. Twins are either monozygotic (TWINS, MONOZYGOTIC) or dizygotic (TWINS, DIZYGOTIC).
Incompetent UTERINE CERVIX is usually diagnosed in the second trimester of PREGNANCY. It is characterized by passive painless cervical dilation in the absence of UTERINE CONTRACTION; BLEEDING; INFECTION; and sometimes with the amniotic sac (AMNIOTIC MEMBRANE) bulging through the partially dilated cervix. Left untreated, this condition may lead to premature pregnancy loss, such as HABITUAL ABORTION.
The surgical closure of the incompetent cervix uteri with suture material.
A term used to describe pregnancies that exceed the upper limit of a normal gestational period. In humans, a prolonged pregnancy is defined as one that extends beyond 42 weeks (294 days) after the first day of the last menstrual period (MENSTRUATION), or birth with gestational age of 41 weeks or more.
The distance between the anterior and posterior poles of the eye, measured either by ULTRASONOGRAPHY or by partial coherence interferometry.
Artificially induced UTERINE CONTRACTION. Generally, LABOR, OBSTETRIC is induced with the intent to cause delivery of the fetus and termination of pregnancy.
The beginning of true OBSTETRIC LABOR which is characterized by the cyclic uterine contractions of increasing frequency, duration, and strength causing CERVICAL DILATATION to begin (LABOR STAGE, FIRST ).
Either one of the two small elongated rectangular bones that together form the bridge of the nose.
Measurement of distances or movements by means of the phenomena caused by the interference of two rays of light (optical interferometry) or of sound (acoustic interferometry).
The number of pregnancies, complete or incomplete, experienced by a female. It is different from PARITY, which is the number of offspring borne. (From Stedman, 26th ed)
Pregnancy in which the mother and/or FETUS are at greater than normal risk of MORBIDITY or MORTALITY. Causes include inadequate PRENATAL CARE, previous obstetrical history (ABORTION, SPONTANEOUS), pre-existing maternal disease, pregnancy-induced disease (GESTATIONAL HYPERTENSION), and MULTIPLE PREGNANCY, as well as advanced maternal age above 35.
The use of statistical and mathematical methods to analyze biological observations and phenomena.
In utero measurement corresponding to the sitting height (crown to rump) of the fetus. Length is considered a more accurate criterion of the age of the fetus than is the weight. The average crown-rump length of the fetus at term is 36 cm. (From Williams Obstetrics, 18th ed, p91)
Any drug treatment modality designed to inhibit UTERINE CONTRACTION. It is used in pregnant women to arrest PREMATURE LABOR.
The statistical reproducibility of measurements (often in a clinical context), including the testing of instrumentation or techniques to obtain reproducible results. The concept includes reproducibility of physiological measurements, which may be used to develop rules to assess probability or prognosis, or response to a stimulus; reproducibility of occurrence of a condition; and reproducibility of experimental results.
UTERINE BLEEDING from a GESTATION of less than 20 weeks without any CERVICAL DILATATION. It is characterized by vaginal bleeding, lower back discomfort, or midline pelvic cramping and a risk factor for MISCARRIAGE.
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.
Maintenance of TELOMERE length. During DNA REPLICATION, chromosome ends loose some of their telomere sequence (TELOMERE SHORTENING.) Various cellular mechanism are involved in repairing, extending, and recapping the telomere ends.
The failure by the observer to measure or identify a phenomenon accurately, which results in an error. Sources for this may be due to the observer's missing an abnormality, or to faulty technique resulting in incorrect test measurement, or to misinterpretation of the data. Two varieties are inter-observer variation (the amount observers vary from one another when reporting on the same material) and intra-observer variation (the amount one observer varies between observations when reporting more than once on the same material).
A terminal section of a chromosome which has a specialized structure and which is involved in chromosomal replication and stability. Its length is believed to be a few hundred base pairs.
Observation of a population for a sufficient number of persons over a sufficient number of years to generate incidence or mortality rates subsequent to the selection of the study group.
The number of offspring a female has borne. It is contrasted with GRAVIDITY, which refers to the number of pregnancies, regardless of outcome.
The condition of carrying two or more FETUSES simultaneously.
Extraction of the FETUS by means of abdominal HYSTEROTOMY.
Delivery of the FETUS and PLACENTA under the care of an obstetrician or a health worker. Obstetric deliveries may involve physical, psychological, medical, or surgical interventions.
In screening and diagnostic tests, the probability that a person with a positive test is a true positive (i.e., has the disease), is referred to as the predictive value of a positive test; whereas, the predictive value of a negative test is the probability that the person with a negative test does not have the disease. Predictive value is related to the sensitivity and specificity of the test.
The loss of some TELOMERE sequence during DNA REPLICATION of the first several base pairs of a linear DNA molecule; or from DNA DAMAGE. Cells have various mechanisms to restore length (TELOMERE HOMEOSTASIS.) Telomere shortening is involved in the progression of CELL AGING.
Measurements of the height, weight, length, area, etc., of the human and animal body or its parts.
Binary classification measures to assess test results. Sensitivity or recall rate is the proportion of true positives. Specificity is the probability of correctly determining the absence of a condition. (From Last, Dictionary of Epidemiology, 2d ed)
Spontaneous tearing of the membranes surrounding the FETUS any time before the onset of OBSTETRIC LABOR. Preterm PROM is membrane rupture before 37 weeks of GESTATION.
Metabolites or derivatives of PROGESTERONE with hydroxyl group substitution at various sites.
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.
A graphic means for assessing the ability of a screening test to discriminate between healthy and diseased persons; may also be used in other studies, e.g., distinguishing stimuli responses as to a faint stimuli or nonstimuli.
The range or frequency distribution of a measurement in a population (of organisms, organs or things) that has not been selected for the presence of disease or abnormality.
Three individuals derived from three FETUSES that were fertilized at or about the same time, developed in the UTERUS simultaneously, and born to the same mother.
A condition of abnormally high AMNIOTIC FLUID volume, such as greater than 2,000 ml in the LAST TRIMESTER and usually diagnosed by ultrasonographic criteria (AMNIOTIC FLUID INDEX). It is associated with maternal DIABETES MELLITUS; MULTIPLE PREGNANCY; CHROMOSOMAL DISORDERS; and congenital abnormalities.
The space in the eye, filled with aqueous humor, bounded anteriorly by the cornea and a small portion of the sclera and posteriorly by a small portion of the ciliary body, the iris, and that part of the crystalline lens which presents through the pupil. (Cline et al., Dictionary of Visual Science, 4th ed, p109)

An infant during the first month after birth.
The genital canal in the female, extending from the UTERUS to the VULVA. (Stedman, 25th ed)
The insertion of drugs into the vagina to treat local infections, neoplasms, or to induce labor. The dosage forms may include medicated pessaries, irrigation fluids, and suppositories.
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.

Transvaginal ultrasound measurement of cervical length and efficacy of misoprostol in first-trimester pregnancy failure. (1/53)

OBJECTIVE: The aim of this study was to assess the role of cervical length measurement in predicting successful treatment, by misoprostol administration, of early (first-trimester) pregnancy failure. METHOD: A prospective study was conducted of all patients who agreed to medical treatment of pregnancy failure. Cervical length and other sonographic variables were measured using pelvic ultrasound before medical treatment began. Measurements were compared between the group with successful medical treatment and the group in whom treatment failed. RESULTS: In 125 women included in the study, the success rate of misoprostol treatment was 64.8%. There were no significant differences between the groups with successful and failed treatment for cervical length (29.9 +/- 9.3 vs. 30.4 +/- 6.8 mm, P = 0.75), distance between gestational sac and 'virtual' cervical internal os (23.9 +/- 13 vs. 26.6 +/- 13 mm, P = 0.26), crown-rump length (8.7 +/- 9.7 vs. 6.7 +/- 8.6 mm, P = 0.25), or gestational sac diameter (31.3 +/- 14 vs. 30.1 +/- 15 mm, P = 0.73). CONCLUSION: Cervical length does not predict the success of misoprostol treatment of first-trimester pregnancy failure.  (+info)

Cervical length as a predictor of preterm delivery: gestational age-related percentiles vs fixed cut-offs. (3/53)

BACKGROUND: To determine whether preterm delivery is more effectively predicted by sonographic cervical length measurement using fixed cut-off or gestational age-specific percentiles. METHODS: One hundred and eight patients hospitalized for suspected preterm labor (PTL) were studied prospectively between the 20th and the 33rd week of gestation. RESULTS: Cervical length below 15 mm, 25 mm and the 2.5th centile showed substantially equivalent odds ratios for delivery within 7 days (7.5, 7.6, and 7.1, respectively), while for delivery before the 34th week the odds ratios varied between 3.6 with cervical length <2.5rh centile and 6.2 with cervical length <25 mm. Moreover, the negative predictive value for delivery within 7 days exceeded 90% when cervical length was above 25 mm, the 10th and the 2.5th percentile, and 85% when above 15 mm. CONCLUSION: The comparison of fixed and gestational age-specific cut-offs demonstrates a better reliability of fixed cut-offs (15 or 25 mm) in predicting preterm delivery, both before 34 weeks and within 7 days of the ultrasound examination.  (+info)

BACKGROUND: Cervical length by transvaginal ultrasound to predict preterm labor is widely used in clinical practice. Virtually no data exist on cervical length measurement to differentiate true from false labor in term patients who present for labor check. False-positive diagnosis of true labor at term may lead to unnecessary hospital admissions, obstetrical interventions, resource utilization, and cost. OBJECTIVE: We sought to determine if cervical length by transvaginal ultrasound can differentiate true from false labor in term patients presenting for labor check ...
BACKGROUND AND SIGNIFICANCE. Preterm birth is a significant problem in the United States and worldwide. Approximately twelve percent of births in the US occur before 37 weeks and are considered preterm. Of these, 80% are considered spontaneous preterm deliveries (as opposed to iatrogenic) and are related to preterm labor or preterm rupture of membranes (Arias, 2003). Certain pregnancy characteristics have been identified to determine those patients at risk for preterm delivery. These include a history of preterm birth (Esplin, 2008), uterine anomalies, multiple gestation, among other things, both modifiable and not (Gardosi, 2000; Ananth, 2006). However, an important risk factor that can be identified is the presence of specific changes in the cervix, such as cervical shortening, and in fact, studies indicate that the risk of spontaneous preterm birth increases as cervical length decreases (Iams, 1996; Hibbard, 2000).. Some authors now advocate the universal screening of all pregnant women for ...

Comparison of the Bishop score, ultrasonographically measured cervical length, and fetal fibronectin assay in predicting time until delivery and type of delivery at term
TUESDAY, Dec. 19, 2017 (HealthDay News) -- Women with a relatively short cervix are at higher risk of preterm delivery, but new research shows that a cervical device may cut that risk substantially.. The Italian study included 300 women with a short cervix. Half of them used a small silicone ring called a cervical pessary, while the other half acted as a control group and did not use the device.. A cervical pessary is designed to keep the cervix closed and to change the inclination of the cervical canal. Previous findings about the effectiveness of the device have been contradictory, the researchers noted.. In this study, women who used the cervical device had about half the risk of preterm birth -- defined as delivery at less than 34 weeks of pregnancy -- compared to women in the control group.. Women who used the pessary also tended to deliver larger, healthier babies that did not require neonatal ICU care, the study found.. Use of the pessary did not cut down on the need for C-section ...

The problem of tail breakage and regeneration in grenadiers instigated the initiation of studies to find a suitable partial length measurement as a replacement for the traditional total length measurement. Studies undertaken in 1978 and 1979 on round nose grenadier, Coryphaenoides rupestris, indicated that the partial length measurements, pre-anus length and anal-fin length, were highly correlated with total length. The anal-fin length was considered to be more practical than pre-anus length, as the latter is sometimes affected by distortion of the anus due to air-bladder expansion and extrusion of intestines when the fish are brought to the deep water. Consequently, the Scientific Council of NAFO at its meeting in June 1980 adopted anal-fin length (tip of snout to base of first anal fin ray) as the standard for measuring roundnose and roughhead grenadiers.

Just as I thought, no UTI for me. I didnt think there was one. I had zero symptoms of it. Just the yeast infection that wasnt very bad either. Anyway, so glad I followed my gut and stayed off of antibiotics when I didnt need them. My biggest issue now is figuring out what is causing this problem with my bowels, that is setting off this horrible cramping and contractions. I had a long discussion with one of the MFM docs yesterday, as they tried to convince me why I dont need cervical length scans...I told them in not so many words that I would insist on it, and I dont care that I have carried a singleton to 37 weeks, Ive never carried twins, and have always had issues with contractions too early and what happened the other night should not be over looked...especially since this isnt the first time Ive experienced this during this pregnancy. I also told them I had no confidence in what Dr.s think since they didnt listen to me and dismissed my concerns that led to them letting my son die, ...

The patients were divided into three subgroups for data analysis. Group 1 included patients with history-indicated cerclage, that is, cerclage was performed in women with obstetric or gynaecological risk factors for spontaneous second-trimester loss or preterm delivery. Group 2 were patients with ultrasound-indicated cerclage, that is, cerclage was performed for women with cervical shortening (,2.5 cm) detected by transvaginal ultrasound examination, without exposure of fetal membranes in the vagina. This group comprised women who planned for history-indicated cerclage with preoperative sonographic finding of shortened cervix; had a history of preterm delivery before 37 weeks or second-trimester miscarriage(s) and underwent ultrasound monitoring of cervical length; or were incidentally found to have sonographic cervical shortening. Regular ultrasound examination was not performed for all patients and, if done, the frequency of monitoring was determined individually. Group 3 consisted of patients ...
PURPOSE: The role of cervical cerclage to prevent preterm birth (PTB) remains controversial. The aim of this study was to identify prognostic factors for cerclage failure among singleton pregnant women following prophylactic cerclage (PC). METHODS: A retrospective analysis of PC was performed in a single center. The main outcome measure was cerclage failure, defined by spontaneous early PTB prior to 32 weeks gestation. Age, BMI, history of instrumentation of the uterus, history of second trimester miscarriage, previous conization, positive vaginal swab prior cerclage, gestational age at time of cerclage, CRP 1 week after cerclage and post-cerclage US changes of cervical length were tested as predictive factors ...

So, long story for a short question. On December 13th I was sent to the hospital from my perinatologists office because my cervical length was down to 2.2 cm. By the next morning, that length was down to 0.3 cm, so I was admitted for bed rest for the remainder of my pregnancy. 11 weeks and a few days later, my water broke (I was 34w5d) and was induced. My DS, Isak, was born early the next morning (Feb 28). Because he was earlier than 36 weeks, he was automatically admitted to the NICU. He was only there for 24 hours and then spent the next 2.5 weeks in the special care nursery. So heres the deal: he nursed the first day a few times. After that day, his bilirubin level shot up, so he became very sleepy and had to go under the lights (the nursing is obviously not related to this, LOL!). He was allowed 30 minutes out of the lights, eight times a day to eat. Because he was slightly premature, he also didnt have the whole suck, swallow, breathe thing down. We live an hour away from the hospital, ...

Unfortunately, the way that most women find out that they have a soft or incompetent cervix is to lose a baby. Recently, more OBs have started routinely measuring cervical length at about 20 weeks of pregnancy, so that treatment can be offered if the cervix is shortened. In women with a history of preterm birth, weekly progesterone injections are now offered with subsequent pregnancies, sometimes in addition to cerclage. A prophylactic cerclage is one that is placed before the cervix begins to shorten. The decision to place a cerclage is based on whether a previous premature birth was felt to be due to an incompetent cervix rather than preterm contractions. Progesterone is a better option to reduce contractions. Cerclage may help to give the cervix extra support, but will not prevent contractions. It is our job as OB providers to review your history with you and plan together what the best course of treatment is for you ...

In enzymology, a hippurate hydrolase (EC 3.5.1.32) is an enzyme that catalyzes the chemical reaction hippurate + H2O ⇌ {\displaystyle \rightleftharpoons } benzoate + glycine Thus, the two substrates of this enzyme are hippurate and H2O, whereas its two products are benzoate and glycine. This enzyme belongs to the family of hydrolases, those acting on carbon-nitrogen bonds other than peptide bonds, specifically in linear amides. The systematic name of this enzyme class is N-benzoylamino-acid amidohydrolase. This enzyme participates in phenylalanine metabolism. Tsoi E, Akmal S, Geerts L, Jeffery B, Nicolaides KH (2006).

The following content is purely based on applying a mathematical equation from Ferron (2017), who obtained it from Sambilay (1990). No other source besides a few used for length measurements have been used besides Ferron (2017). I am not a mathematician and my calculations may have mistakes, which is why Ive shown all of my work in case any of you want to check my math. The formulas themselves may possibly be updated/invalidated by later studies. Please take this with the finest grain of salt. Apparently, Cretoxyrhina may possibly be the one of the, if not the fastest shark known so far according to a set of equations. When reading through the scientific paper Ferron (2017), I found out that the equation he used to make his speed calculations are ones that I might be able to do myself, so here I am making a post that consists of a wall of algebraic nonsense to try to see for myself on things. Ferron (2017) used an equation that was developed by Sambilay (1990) (which I unfortunately cannot ...

Does anyone with an IC (incompetent cervix) have a cervical pessary success story? Im reading that in Europe theyre used a lot more frequently than the cerclage, but there isnt enough data for them to be the go to here. Im bothered that my mfm and ob have never even mentioned them to me... as the scariest part of cerclage for me is the risk of infection, and with a pessary there is very little concern. My history of ic is just my cervix opening up, no warning signs, around 28 weeks my first pregnancy and 21 with my second. So have any of you had a good outcome with just a pessary placed, no stitch? Were you on a more strict bedrest?
7. Rapid Fetal fibronectin alone and in combination with cervical length in predicting preterm delivery in a tertiary hospital in the Philippines from 2009-2012: A Retrospective Cohort Study by Joanne Pauline Chua-Ursua, M.D. (The Medical City) ...
Last weekend I was experiencing more contractions throughout the day. A lot of those came in the evenings which was a typical pattern with my uterus with the twins pregnancy. Even after laying down and drinking lots and lots of water the contractions were picking up to be as much as 6 in one hour a few different times. Because of their frequency I called my Obgyn. I then went in to see her and to have a Fetal fibronectin test done. This test is done to see if I were to go into labor within the next 2 weeks. Luckily, the test came back negative so the chances of that are less than 1%! I also had another ultra sound done that same day to check my cervical length just in case these contractions were causing it to shorten. My cervix still measured around 4 c.m. give or take and is still closed/not dilated ...

OBJECTIVE-Genital tract infection accounts for ~ 25-40% of all pre-term births. We sought to assess the relationship between preterm birth and selected vaginal bacterial taxa associated with preterm birth either directly or through their association with bacterial vaginosis (BV). STUDY DESIGN-Vaginal fluid for Gram stain was collected between 17 and 22 weeks gestation as part of a randomized trial of ultrasound-indicated cerclage for preterm birth prevention in women at high risk for recurrent spontaneous preterm birth. Bacterial DNA was extracted from the Gram stain slides and analyzed using quantitative PCR. RESULTS-Among the 499 participants, Mycoplasma was positively correlated with increased risk of preterm (RR = 1.83; 95% CI: 1.52,2.22) as was Mobiluncus (RR=1.36; 95% CI: 1.07, 1.73) and Atopobium (RR=1.44; 95% CI: 1.1, 1.87). However, there were strong interactions between race/ethnic group and the presence of these and other individual taxa on risk of preterm birth. By contrast, BVAB3 ...

INTRODUCTION: Preterm cervical shortening and cervical insufficiency may be caused by a constitutional weakness of the cervix. The aim of this study was to assess the cervical collagen concentration in non-pregnant women with a history of cervical insufficiency or of a short cervix in the second trimester of pregnancy.. MATERIAL AND METHODS: In this case-control study we included non-pregnant women one year or more after pregnancy: 55 controls with a history of normal delivery; 27 women with a history of cervical insufficiency; and 10 women with a history of a short cervix (,5th percentile) and 10 women with a history of a long cervix (,95th percentile) at gestational weeks 18-20. We obtained biopsies (3 × 3-4 mm) from the ectocervix and determined the collagen concentration by measuring the hydroxyproline concentration.. RESULTS: Women with cervical insufficiency had lower collagen concentrations (63.5 ± 5.1%; mean ± SD) compared with controls (68.2 ± 5.4%; p = 0.0004); area under the ROC ...

Cervical length assessment is just one of several powerful tools for detecting or excluding patients at risk for preterm birth. An expert tells how to assess and counsel a patient pregnant with triplets on her chances of carrying all three fetuses to at least 32 weeks.
For example, with nonwoven and extensible products, machine draws can be standardized to produce uniform basis weight and thickness properties. For tissue manufacture, the crepe ratio can now be accurately measured between the Yankee dryer and the reel to control and optimize the bulk and hand-feel properties. Also with orientated film and sheet polymer products, the actual MDO stretch can be measured on-line to help achieve the correct thickness, quality and performance properties. Paper and board grades also benefit from accurate draw measurements as by setting sectional draw targets from the forming area through to the reel to avoid breaks, improve drying and reduce cross direction shrinkage,. The benefits of accurate length measurement are obvious. By eliminating slippage or errors with contacting encoders, this reduces product give-away and/or short length delivery claims. But there are other benefits. By matching rolls of equivalent length for multi-ply winding operations such as tissue ...
