Abstract

To evaluate different sonographic methods for the prediction of the difficulty and the success of operative vaginal delivery (OPD).A prospective study was performed on 45 term singleton uncomplicated pregnancies with prolonged 2nd stage of delivery with cephalic presentation. Measurements of the fetal head, relations between the fetal head and maternal pelvic parameters during rest and during maternal pushing were taken using translabial ultrasound.29 cases of OPD were successful and 4 cases failed ending in cesarean section. The passage of the biparietal diameter (BPD) of the infrapubic line (IPL) was statistically correlated with the success of OPD. Head station, passage of the BPD of the IPL, percentage of head after the IPL, circumference of head after IPL were all correlated with the difficulty of OPD. When the distance between the widest diameter of the head and the IPL is 1.2 cm, there is a 90 % probability of success of OPD. When that distance is 3.3 cm, there is 90 % probability of cesarean section. When the percentage of head beyond the IPL was 54 %, there was 90 % probability of successful OPD.Translabial ultrasound is useful in the prediction of the difficulty and the success of OPD. The higher the extent of head that passed the IPL, the less difficult the OPD and the greater the success rate of the OPD.

Abstract

A measurement of direct photon production in {sup 208}Pb+ {sup 208}Pb collisions at 158A GeV has been carried out in the CERN WA98 experiment. The invariant yield of direct photons in central collisions is extracted as a function of transverse momentum in the interval 0.5 1.5 GeV/c . The result constitutes the first observation of direct photons in ultrarelativistic heavy-ion collisions. It could be significant for diagnosis of quark-gluon-plasma formation.

Abstract

The Delta(++)-resonance production in central 158 A GeV Pb-208 + Pb-208 collisions at the CERN SPS has been studied. The Delta(++) production was estimated from the invariant mass spectrum of p pi(+)-pairs by subtracting a mixed event background. The measured Delta(++) abundance is compared with the results from other experiments at lower energies, and with a model calculation assuming thermal and chemical equilibrium.

Abstract

An event-by-event analysis of the azimuthal angular correlation with respect to the reaction plane has been carried out for K+ and pi(+) emission near mid-rapidity in 158 A . GeV Pb + Pb collisions. In semi-central collisions, K+ mesons are found to be preferentially emitted out of the reaction plane, while pi(+) mesons are emitted in the reaction plane. The results suggest that the kaon emission is influenced by in-medium potential effects in addition to collective flow effects. (C) 1999 Published by Elsevier Science B.V. All rights reserved.

Abstract

Neutral pion production in central 158A GeV [sup 208]Pb+ [sup 208] Pb collisions has been studied in the WA98 experiment at the CERN Super Proton Synchrotron. The [pi][sup 0] transverse mass spectrum has been analyzed in terms of a thermal model with hydrodynamic expansion. The high accuracy and large kinematic coverage of the measurement allow one to limit previously noted ambiguities in the extracted freeze-out parameters. The results are shown to be sensitive to the shape of the velocity distribution at freeze-out. [copyright] [ital 1999] [ital The American Physical Society ]

Abstract

The production of neutral pions in 158A GeV {sup 208}Pb+ {sup 208}Pb collisions has been studied in the WA98 experiment at the CERN Super Proton Synchrotron (SPS). Transverse momentum spectra are studied for the range 0.3{le}m{sub T}{minus}m{sub 0}{le}4.0 GeV /c . The results for central collisions are compared to various models. The centrality dependence of the neutral pion spectral shape and yield is investigated. An invariance of the spectral shape and a simple scaling of the yield with the number of participating nucleons is observed for centralities with greater than about 30thinspthinspparticipating nucleons. This is most naturally explained by assuming an equilibrated system. {copyright} {ital 1998} {ital The American Physical Society }

Abstract

We present recent results obtained with the WA98 experiment at CERN SPS. The experiment consists of large acceptance hadron and photon spectrometers which allow to study many aspects of heavy ion collisions. We use event-by-event measurements of charged and neutral particle multiplicity to establish the limit on the prodution of Disoriented Chiral Condensates. We use the Plastic Ball detector together with a set of tracking chambers to study collective flow. The tracking chambers together with the excellent particle identification allow us to study the production of Δ ++ . The high resolution photon calorimeter array allows us to study inclusive photon and π 0 spectra and search for excess direct photons.

Abstract

Anisotropic transverse flow has been studied with a magnetic spectrometer at midrapidity and the Plastic Ball detector at target rapidity in the WA98 experiment. Our preliminary results show the existence of directed and elliptic flow in semi-central Pb+Pb collisions. The magnitude of the directed flow is found to be significantly smaller than those observed at the AGS energies.

Abstract

The restoration of chiral symmetry and its subsequent breaking through a phase transition has been predicted to create regions of Disoriented Chiral Condensates (DCC). This phenomenon has been predicted to cause anomalous fluctuations in the relative production of charged and neutral pions in high-energy hadronic and nuclear collisions. The WA98 experiment has been used to measure charged and photon multiplicities in the central region of 158 AGeV Pb+Pb collisions at the CERN SPS. In a sample of 212646 events, no clear DCC signal can be distinguished. Using a simple DCC model, we have set a 90% C.L. upper limit on the maximum DCC production allowed by the data., 20 Pages, LaTeX, uses elsart.cls, 8 eps figures included, submitted to Physics Letters B

Abstract

The first evidence of directed flow at 158 A GeV Pb + Pb collisions is observed using the Plastic Ball detector in WA98 experiment. The azimuthal angle of the total transverse energy, Phi(o), is determined for each event using the observed protons in the Plastic Ball. A clear azimuthal asymmetry of fragments is observed with respect to Phi(o). The degree of azimuthal asymmetry is found to be largest in mid-central collisions, which is consistent with the picture of the collective flow.The p(t) spectra of particles measured in the mid-rapidity spectrometer has been studied in conjunction with the Plastic Ball, and different p(t) slopes with respect to Phi(o) for proton and pi(+) are observed.

Abstract

The mitochondrial cytochrome c oxidase subunit I (COI) can serve as a fast and accurate marker for the identification of animal species, and has been applied in a number of studies on birds. We here sequenced the COI gene for 387 individuals of 147 species of birds from the Netherlands, with 83 species being represented by > 2 sequences. The Netherlands occupies a small geographic area and 95% of all samples were collected within a 50 km radius from one another. The intraspecific divergences averaged 0.29% among this assemblage, but most values were lower; the interspecific divergences averaged 9.54%. In all, 95% of species were represented by a unique barcode, with 6 species of gulls and skua (Larus and Stercorarius) having at least one shared barcode. This is best explained by these species representing recent radiations with ongoing hybridization. In contrast, one species, the Lesser Whitethroat Sylvia curruca showed deep divergences, averaging 5.76% and up to 8.68% between individuals. These possibly represent two distinct taxa, S. curruca and S. blythi, both clearly separated in a haplotype network analysis. Our study adds to a growing body of DNA barcodes that have become available for birds, and shows that a DNA barcoding approach enables to identify known Dutch bird species with a very high resolution. In addition some species were flagged up for further detailed taxonomic investigation, illustrating that even in ornithologically well-known areas such as the Netherlands, more is to be learned about the birds that are present.

Abstract

Antibiotic susceptibility surveillance testing was performed on clinical isolates of Neisseria gonorrhoeae collected in September 1989 in the Philippines. beta-Lactamase was produced by 77 (55%) of 140 isolates. In vitro MIC testing revealed significant resistance to penicillin (MIC for 90% of isolates [MIC90], greater than 64 micrograms/ml), tetracycline (MIC90, 4 micrograms/ml), and cefmetazole (MIC90, 8 micrograms/ml). Spectinomycin resistance was rare (10 of 117), but the MIC90 was 32 micrograms/ml. Isolates were susceptible to fluoroquinolones and cephalosporins at the time of this survey, as evidenced by the MIC90s of ciprofloxacin (0.25 microgram/ml), norfloxacin (2.0 micrograms/ml), ofloxacin (0.625 microgram/ml), cefpodoxime (2.0 micrograms/ml), cefotaxime (1.0 microgram/ml), ceftazidime (0.25 microgram/ml), ceftizoxime (0.25 microgram/ml), and ceftriaxone (0.06 microgram/ml). To date, ceftriaxone resistance has not emerged, despite the widespread use of this antibiotic in the Philippines.

Abstract

To assess the incidence and complications of shoulder dystocia and whether those complications could be avoided.Retrospective analysis of shoulder dystocia between 1996 and 1999 to determine whether macrosomia, diabetes, height of head at full dilatation, length of second stage or instrumental delivery could predict shoulder dystocia. Fetal asphyxia, brachial plexus injury, maneuvers used to free the shoulders and experience of the attendant were also assessed.There were 56 cases of shoulder dystocia in 24,000 births, 59% after spontaneous delivery. McRoberts maneuver was used in 48 deliveries but sufficed as a solitary procedure in nine cases. The addition of suprapubic pressure was sufficient for 25 patients and 27 when bilateral episiotomy was also used. Corkscrew procedures were required in 12 patients. Midwives were involved in 35 cases and required assistance in 27. Macrosomia4,000 g was a feature in 20 infants and diabetes in 6. Neither the height of the head nor the length of the second stage was helpful. There were 13 cases of Erb's palsy, seven after vacuum delivery and six after spontaneous delivery. Eight of these cases were associated with McRoberts procedure and suprapubic pressure, two with no procedure and three with the corkscrew procedure.If all infants4,000 g had been delivered by cesarean section, there still would have been 36 cases of shoulder dystocia. If the ultrasonically estimated weight were used to select patients for cesarean section, seven cases would have been diagnosed. To lessen the degree and incidence of fetal injury, labor ward staff are urged to become as familiar as possible with the techniques of freeing the shoulders.

Abstract

First results on the measurement of localized fluctuations in the multiplicity of charged particles and photons produced in central 158 A GeV Pb+Pb collisions are presented. The charged versus neutral correlations in common phase space regions of varying azimuthal size are analyzed by two different methods. The measured results are compared to those from simulations and to those from different types of mixed events. The comparison indicates the presence of non-statistical fluctuations in both charged particle and photon multiplicities in limited azimuthal regions. However, no correlated charge-neutral fluctuations are observed., Comment: 5 pages, 3 postscript figures

Abstract

Results from the multiplicity distributions of inclusive photons and charged particles, scaling of particle multiplicities, event-by-event multiplicity fluctuations, and charged-neutral fluctuations in 158$\cdot A$ GeV Pb+Pb collisions are presented and discussed. A scaling of charged particle multiplicity as $N_{part}^{1.07\pm 0.05}$ and photons as $N_{part}^{1.12\pm 0.03}$ have been observed, indicating violation of naive wounded nucleon model. The analysis of localized charged-neutral fluctuation indicates a model-independent demonstration of non-statistical fluctuations in both charged particles and photons in limited azimuthal regions. However, no correlated charged-neutral fluctuations are observed., Talk given at the International Symposium on Nuclear Physics (ISNP-2000), Mumbai, India, 18-22 Dec 2000, Proceedings to be published in Pramana, Journal of Physics

Abstract

The authors have studied the production of hadrons and photons in the reaction Pb(Pb, X) at 158 A.GeV. They have applied the discrete wavelet transform to the photon and charged-particle correlations in order to obtain a set of father function coefficients. They try to explain the multiplicity fluctuations by means of localized disoriented chiral condensate domains. (7 refs). A detailed analysis of the phase space distributions of charged particles and photons have been carried out using two independent methods. The results indicate the presence of nonstatistical fluctuations in localized regions of phase space.

Abstract

Study of elliptic emission for identified particles has been performed in 158A GeV Pb+Pb collisions near mid-rapidity region. Our preliminary results indicate the existence of the in-plane elliptic emission for {pi}{sup +} and proton, and out-of-plane elliptic emission for K+ in semi-central collisions. In addition, two-pion interferometry is studied as a function of the pair direction relative to the reaction plane.

Abstract

Disoriented Chiral Condensates (DCC) have been predicted to form in high energy heavy ion collisions where the approximate chiral symmetry of QCD has been restored. This leads to large imbalances in the production of charged to neutral pions. Sophisticated analysis methods are being developed to disentangle DCC events out of the large background of events with conventionally produced particles. We present a short review of current analysis methods and future prospects., 12 pages, 5 figures.

Abstract

It has been shown that soil management under organic farming can enhance soil organic carbon, thereby mitigating atmospheric greenhouse gas increases, but until now quantitative evaluations based on long term experiments are scarce, especially under Mediterranean conditions. Changes in soil organic carbon (SOC) content were examined in response to organic management with cover crops in a Mediterranean citrus plantation using 21 years of survey data. Soil organic carbon increase was more apparent 5 years after a land management change suggesting that, for citrus plantations on Mediterranean conditions, studies should be longer than five years in duration. Soil organic carbon sequestration rate did not significantly change during the 21 years of observation, with values ranging from -1.10 Mg C ha-1 y-1 to 1.89 Mg C ha-1 y-1. After 21 years, 61 Mg CO2 ha-1 were sequestered in long-lived soil C pools. These findings demonstrate that organic management is an effective strategy to restore or increase SOC content in Mediterranean citrus systems.

Abstract

Rainfall is the key factor to understand soil erosion processes, mechanisms, and rates. Most research was conducted to determine rainfall characteristics and their relationship with soil erosion (erosivity) but there is little information about how atmospheric patterns control soil losses, and this is important to enable sustainable environmental planning and risk prevention. We investigated the temporal and spatial variability of the relationships of rainfall, runoff, and sediment yield with atmospheric patterns (weather types, WTs) in the western Mediterranean basin. For this purpose, we analyzed a large database of rainfall events collected between 1985 and 2015 in 46 experimental plots and catchments with the aim to: (i) evaluate seasonal differences in the contribution of rainfall, runoff, and sediment yield produced by the WTs; and (ii) to analyze the seasonal efficiency of the different WTs (relation frequency and magnitude) related to rainfall, runoff, and sediment yield. The results indicate two different temporal patterns: the first weather type exhibits (during the cold period: autumn and winter) westerly flows that produce the highest rainfall, runoff, and sediment yield values throughout the territory; the second weather type exhibits easterly flows that predominate during the warm period (spring and summer) and it is located on the Mediterranean coast of the Iberian Peninsula. However, the cyclonic situations present high frequency throughout the whole year with a large influence extended around the western Mediterranean basin. Contrary, the anticyclonic situations, despite of its high frequency, do not contribute significantly to the total rainfall, runoff, and sediment (showing the lowest efficiency) because of atmospheric stability that currently characterize this atmospheric pattern. Our approach helps to better understand the relationship of WTs on the seasonal and spatial variability of rainfall, runoff and sediment yield with a regional scale based on the large dataset and number of soil erosion experimental stations.

Abstract

To sensitize practitioners to the application of feminism to family programs, three feminist assumptions are identified: Women are oppressed, the personal is political, and feminists have double consciousness. From these assumptions, principles of feminist practice are derived and the ways in which these principles are operationalized in programs published in Family Relations are identified. We discuss what it means to be a feminist practitioner, the difficulty of translating feminist vision into practice, and the need for a practical literature on feminist family programming. Finally, we encourage family practitioners to reflect on the assumptions underlying their practice. [ABSTRACT FROM AUTHOR]

Abstract

We have studied the azimuthal angle distributions of identified charged particles near mid-rapidity region in semi-central Pb+Pb collisions at SPS energies. Our preliminary results show that π+ mesons and protons seem to be emitted in the reaction plane, while out-of-plane for K+ mesons. This phenomenon might be explained by the existence of another possible effect such as in-medium potential as well as the collective motion.

Abstract

To sensitize practitioners to the application of feminism to family programs, three feminist assumptions are identified: Women are oppressed, the personal is political, and feminists have double consciousness. From these assumptions, principles of feminist practice are derived and the ways in which these principles are operationalized in programs published in Family Relations are identified. We discuss what it means to be a feminist practitioner, the difficulty of translating feminist vision into practice, and the need for a practical literature on feminist family programming. Finally, we encourage family practitioners to reflect on the assumptions underlying their practice. O ver the years, Family Relations has published a multitude of articles descriptive and/or evaluative of programs for individuals and families. These programs have been developed in response to a variety of needs, ranging from informational to therapeutic. Of particular interest in this issue of the journal is family programming derived from a feminist philosophy. Such programs represent the minority of programs available to individuals and families today and have only occasionally been reflected in the pages of Family Relations. Feminist programs are helpful to individuals and families because their underlying values and assumptions are directed toward servicing those in need rather than the interests of service providers, the market economy, or the status quo. The purpose of this article is to sensitize readers of Family Relations to the fundamentals of feminism and its application to programs for families. In the spirit of offering new possibilities for family practitioners to contemplate, we encourage practitioners to reflect on the assumptions that underlie their programs and consider alternative (somewhat less conventional) ways of meeting their clients' needs. To do this, programs that Family Relations' readers know best are examined; that is, programs reported in the journal. In the process, the extent to which programs published in Family Relations reflect feminist values and assumptions is discussed. Throughout, both the vision and the practice of feminist programs for families as well as the gap between vision and practice are considered. Rather than drawing only on programs offered by avowed feminists, we show how the programs of some nonfeminists share several feminist values and assumptions. Retained, however, is the notion that there is something distinctive about a comprehensive feminist approach. The purpose is not to criticize traditional programs but to offer yet another way, a feminist way, of helping families in need. What follows is a description of the values and assumptions of feminism, the identification and explanation of principles of feminist practice, illustrations of how programs published in Family Relations met these principles, and an overall discussion of the issues raised in and findings of this article.

Abstract

Background: Currently, the use of FE is decreasing and neonatal adverse outcomes following FE are underreported. We aimed to evaluate the rate of neonatal adverse outcomes in current obstetric practice at two university hospitals with a low FE volume., Methods: A multicentre retrospective study. All singleton pregnancies delivered by forceps extraction between 2011 and 2020 were analyzed. The characteristics of the deliveries with a composite neonatal adverse outcome (CNAO) were analyzed and compared with those without., Results: The study cohort included 861 neonates delivered by FE. The CNAO was recorded in 131 (15.2%). Women in the CNAO group gained less weight during pregnancy (mean 13 kg vs. 15 kg, p  = .014). Factors found to be associated with CNAO were preterm delivery (gestational age < 37° /7 ) (26 (19.8%) vs. 44 (6.0%), OR [95% CI]: 3.86 (2.28-6.52), p  < .001), low birth weight (23 (17.6%) vs. 44 (6.0%), OR [95% CI] 3.32 (1.92-5.71), p  < .001), and smaller head circumference (329 vs. 331 mm, OR [95% CI] 0.79 (0.67-0.93), p  = .035). In a multivariate analysis, gestational age (adjusted OR [95% CI] 0.672 (0.546-0.826), p  < .001) and maternal weight gain during pregnancy (adjusted OR [95% CI]: 0.950 (0.904-0.998), p  = .042), were both negatively associated with CNAO. Among term deliveries, the only factor found to be independently associated with CNAO was maternal weight gain during pregnancy (adjusted OR [95% CI]: 0.951 (0.910-0.994), p  = .025)., Conclusions: In the setting of low volume FE, this mode of delivery is associated with a relatively low rate of neonatal morbidity., Synopsis: Performance of forceps extraction in the setting of low volume practice is associated with a relatively low rate of neonatal morbidity.

Abstract

Purpose: The aim of this study is to evaluate the effect of uterine exteriorization versus intraperitoneal repair, in first compared to repeat cesarean delivery., Methods: A prospective randomized control single-blinded trial conducted in a single tertiary center between March 2014 and March 2015, including 32 and 63 women in first and recurrent cesarean sections, respectively. Inclusion criteria were elective operation and gestational age ≥37 weeks. Operative outcomes were compared between the groups including mean operative time, blood loss, hypotension, perioperative nausea and pain. Post-operative outcomes were further compared, including post-operative analgesia demand, first recognized bowel movement, nausea, length of hospital stay, fever, endometritis surgical site infection rate, and total satisfaction., Results: During the study period, 45 and 50 women were designated for uterine exteriorization and intraperitoneal uterine repair, respectively. Mean blood loss was 452 cc (±10.44) for the extraperitoneal compared to 540 cc (±29.83) for the intraperitoneal uterine repair group ( p  = .004). No other significant differences in either intraoperative or postoperative complications were demonstrated in and between the groups., Conclusion: Intraperitoneal repair of uterine incision is associated with higher operative blood loss compared to uterine exteriorization. No other differences in operative and postoperative complication rates were found between the groups.

Abstract

Background: Postpancreatectomy haemorrhage (PPH) is a rare but potentially fatal complication after pancreatoduodenectomy. Preventive strategies are lacking with scarce data for support. The aim of this study was to investigate whether a prophylactic falciform ligament wrap around the hepatic and gastroduodenal artery can prevent PPH from these vessels., Methods: In a randomized, controlled, multicentre trial, patients who were scheduled for elective open partial pancreatoduodenectomy with pancreatojejunostomy between 5 November 2015 and 2 April 2020 were randomly allocated in a 1 : 1 ratio to undergo pancreatoduodenectomy with (intervention) or without (control) a falciform ligament wrap around the hepatic artery. The primary endpoint was the rate of clinically relevant PPH from the hepatic artery or gastroduodenal artery stump within 3 months after pancreatoduodenectomy. Secondary endpoints were the rates of associated postoperative complications, for example postoperative pancreatic fistula (POPF) and PPH., Results: Altogether, 445 patients were randomized with 222 and 223 in each group. Among the patients included in modified intention-to-treat analysis (207 in the intervention group and 210 in the control group), the primary endpoint was observed in six of 207 in the intervention group compared with 15 of 210 in the control group (2.9 versus 7.1 per cent respectively; odds ratio 0.39 (95 per cent c.i. 0.15 to 1.02); P = 0.071). Per protocol analysis showed a significant reduction in the intervention group (odds ratio 0.26 (95 per cent c.i. 0.09 to 0.80); P = 0.017). A soft pancreas texture (43 per cent) and the rate of a clinically relevant POPF were evenly (20 per cent) distributed between the groups. The rate of any clinically relevant PPH including the primary endpoint and other bleeding sites was not significantly different between intervention and control groups (9.7 versus 14.8 per cent respectively)., Conclusion: A falciform ligament wrap may reduce PPH from the hepatic artery or gastroduodenal artery stump and should be considered during pancreatoduodenectomy., Registration Number: NCT02588066 (http://www.clinicaltrials.gov)., (© The Author(s) 2021.

Abstract

Purpose: While the increased rates of high degree perineal tears were previously associated with the use of forceps, in the current era of low volume of forceps practice, factors associated with the occurrence of this potential complication remain understudied. We aim to evaluate factors associated with obstetric anal sphincter injury (OASIS) in obstetric units with a low volume forceps practice., Methods: A retrospective cohort study was conducted at two tertiary medical centers. All singleton pregnancies delivered by forceps extraction between 2011 and 2019 were analyzed. Women who experienced anal sphincter injury were compared to those who did not., Results: The study cohort included 764 forceps deliveries. There were 19 (2.5%) cases of OASIS. Women with anal sphincter injury had higher rates of gestational diabetes mellitus (21% vs. 5.6%, OR [95% CI] 4.46 (1.41-14.04), p = 0.02). Birth weights and the rate of macrosomia did not differ between groups. Induction of labor was more common among the OASIS group (68% vs. 41.7%, OR [95% CI] 3.0 (1.1-8.0), p = 0.02). Sequential use of forceps (after failed vacuum attempt) was associated with OASIS (8 (42%) vs. 76 (10.2%), OR [95% CI] 6.4 (2.5-16.4), p < 0.001). In a multivariate logistic regression, sequential forceps was the only factor independently associated with OASIS (OR [95% CI] 4.7 (1.3-18.2), p = 0.02)., Conclusions: Rate of OASIS was relatively low in the current cohort. Sequential use of forceps was found to be the most important determinant in OASIS occurrence.

Abstract

Objectives: To assess if measurement of the head progression distance (PD) during the first stage of labor in nulliparous women can predict the delivery method. Methods: A prospective study was conducted on consecutive nulliparous women beyond 37 week's gestation during the first stage of labor. Transperineal ultrasound was performed to assess the PD. Analysis was performed on the relationships between PD during rest and during voluntary pushing and the fetal and maternal characteristics, delivery mode, and immediate postnatal outcomes. Results: Eighty seven suitable nulliparous women were suitable for analysis. PD was found to be significantly longer in women who delivered vaginally (VD) compared to those who underwent a cesarean section (CS) for obstructed labor: PD at rest was 2.51 ± 1.71 cm in women who delivered vaginally compared to 1.48 ± 1.9 cm in women who delivered by CS ( p  = .01). The PD during pushing was 3.43 ± 1.8 cm for a VD compared to 1.5 ± 2.1 cm for CS ( p  = .015). Logistic regression and receiver-operating characteristics curve analysis demonstrated a moderate predictive value of PD with respect to the mode of delivery (area under the curve was 0.67 during both resting and pushing period). Conclusion: PD measurements during the first stage of labor among nulliparous women differ significantly both in rest and during pushing between patients who delivered vaginally compared to CS and can therefore assist in predicting the mode of delivery.

Abstract

Purpose: To investigate the correlation between the angle of progression and the clinical fetal head station (FHS) during the second stage of labor, and to build reference range., Materials and Methods: A prospective, observational study was conducted. Women carrying singleton term pregnancies were enrolled during the second stage of labor. FHS was assessed manually by a senior obstetrician, while the angle of progression (AOP) was assessed by transperineal ultrasound (TPU). Both examiners were blinded to each others results. The correlation between the sonographic AOP and the clinical FHS was analyzed., Results: Seventy patients comprised the study group. Clinical FHS demonstrated an excellent correlation with the sonographic measurement of AOP (Pearson's Correlation 0.642, p < 0.001). This correlation was best described by a cubic regression according to the formula: 123.800 + 10.290 × FHS -2.889 * FHS +0.910, (r 2  = 0.423, p < .001). After aggregation of the mean AOP per FHS, the relative predicted centiles values and standard deviation were calculated. The mean Z score between measured and predicted values of the AOP for a given FHS was 0.007 (range -0.13 to +0.006)., Conclusions: Our results demonstrate a significant correlation between the clinical FHS and the TPU measured AOP. These standardized sonographic values may serve the obstetrician as a reliable, objective auxiliary tool for the evaluation of the FHS during the second stage of labor.
