Índice de masa corporal y aumento de peso en el embarazo. Resultado obstétrico de la inducción de parto

Objective

To determine the obstetric results of labor induction in relation to body mass index (BMI) and gestational weight gain at the Leon Hospital between January and March, 2008.

Material and method

We conducted a prospective cohort study of 127 labor inductions. The variables included were the medical reason for induction, the procedures employed for cervical ripening and induction, maternal age at the end of pregnancy, type of labor, parity, initial Bishop's score, BMI, weight, height, gestational weight gain, neonatal weight and Apgar test at 1 and 5 minutes.

Results

Inductions were performed in 21.3% of births, while vaginal delivery was achieved in 81.1%. A total of 36.2% of the patients were overweight, 21.2% were obese and 4.7% were morbidly obese.

Conclusions

A non-statistically significant association was observed between failure of vaginal delivery and BMI (P = .08) and body weight gain (P = .07). These two variables seem to increase the chances of failure of cervical ripening and induction of labor, increasing the percentage of cesarean sections.     

Campaña de lucha contra el cáncer de cuello uterino en Guinea-Bissau. Estudio de las citologías de un trimestre

Objective

To study 300 cytologies from a single trimester, within a campaign against uterine cervical cancer in Guinea-Bissau.

Design

We compared 300 cytologies from Guinea-Bissau with 880 cytologies performed in a single month in autochthonous women attending our hospital for vaginal infections and cervical lesions.

Results

Significant differences between women in Guinea-Bissau and autochthonous women were found in Trichomonal infection (2% versus 0,34%, respectively; P < .001) and in low-grade squamous intraepithelial lesions (2% versus 0,68%, respectively; P = .05). One case of cervical cancer was detected in a 75-year-old multiparous woman. The mean number of deceased children in these women was 2 (range 1-8).

Conclusions

To avoid both cervical cancer and neonatal mortality, a permanent program for the early detection of cervical cancer in Guinea-Bissau is clearly needed, together with family planning, prenatal care and obstetric assistance.     

Ayuno vs. dieta líquida. Estudio aleatorizado controlado para evaluar la duración de la labor de parto,tasa de cesáreas y satisfacción con la labor

Aim

To evaluate the benefits of allowing oral intake of clear liquids in terms of labor duration, the cesarean section rate, and personal satisfaction.

Methods

A randomized controlled trial was carried out to assess the effects of a clear liquid diet in a low risk population. The primary outcome was labor duration. The secondary outcome was the incidence of cesarean section. A satisfaction survey was performed within the first 2 h after delivery to evaluate the patient's perception of labor.

Results

A total of 348 patients were randomized. The mean duration of labor was 257.75 min in the liquid diet group and 288.40 min in the fasting group (p = NS). There was no statistically significant difference (per-protocol analysis and intention-to-treat analysis) in the cesarean section rate.Patients reported greater satisfaction when allowed to drink during labor than when fasting.

Conclusion

A clear liquid diet during labor did not alter the duration of labor or the cesarean section rate. Allowing a liquid diet during labor was associated with a better perception of the birth process and a higher degree of satisfaction.     

Impacto de la edad materna avanzada en las complicaciones obstétricas y perinatales de las gestaciones gemelares

Objective

To evaluate the pregnancy and perinatal outcomes of twin gestations in women aged 35 or older.

Material and methods

We designed a retrospective cohort study. Maternal complications, mode of delivery and perinatal outcomes were compared in 229 women who delivered at age 35 or older and in 374 women who delivered at age less than 35 years. The computerized database and medical records of pregnant women attending the Miguel Servet University Hospital from January 2001 to December 2007 were retrospectively reviewed.

Results

Older women had an increased risk of conceptions after assisted reproductive techniques (p > 0.001), dichorionic pregnancies (p > 0.001) and gestational diabetes (p = 0.007; 95% CI: 1.119-3.19). There was no significant association between older maternal age and an increased incidence of preterm labor, premature rupture of membranes, fetal growth restriction, cesarean delivery or perinatal mortality.

Conclusion

Based on our data and previous studies, advanced maternal age in twin pregnancies does not seem to significantly increase obstetric complications or adverse perinatal results.     

Influencia de la edad y de las técnicas de reproducción asistida en nuestros resultados obstétricos y perinatales

Objective

To evaluate the influence of age ≥ 40 years and ART in our obstetric and perinatal outcomes.

Material and methods

Retrospective study of 14805 singleton pregnancies in our Institute from January 1, 2000 to December 31, 2006. We compared obstetric and perinatal outcome between: Age group: women ≥ 40 years (N = 557) vs. group of women < 40 years (N = 14248); ART group < 40 years: ART pregnancies (N = 1150) vs. spontaneous pregnancies (N = 13098); ART group ≥ 40 years: ART pregnancies (N = 126) vs. spontaneous pregnancies (N = 431).Results: Age ≥ 40 years is significantly associated with preterm birth under 34 weeks (odds ratio [OR] = 2.148 [1.237-3.730]), gestational diabetes (OR = 2.25 [1.799-2.815]), placenta previa (OR = 3.346 [1.516-7.386]), caesarean delivery (OR = 1.831 [1.539-2.177]), and peripartum hysterectomy (OR = 6.414 [1.359-2.177]). In the ART group < 40 years assisted conception (ART) is significantly associated with preterm birth under 37 (OR = 1.67 [1.337-2.088]) and 34 weeks (OR = 1.8 [1.162-2.822]), with gestational diabetes (OR = 1.5 [1.273-1.844]), pre-eclampsia (OR = 2.1 [1.456-3.164]), placenta previa (OR = 5.29 [2.973-9.437]), choriamniotic infection (OR = 3.8 [1.029-14.072]), caesarean delivery (OR = 1.5 [1.346-1.737]) and low birth weight ≤ 2500 g. (OR = 1.67 [1.329-2.114]) and ≤ 1500 g. (OR = 2.44 [1.442-4.135]). In the ART group ≥ 40 years we only find a significantly increased rate of caesarean delivery (OR = 1.76 [1.183-2.635]) in ART group vs. spontaneous pregnancy group.

Conclusions

Age ≥ 40 years increases the risk of adverse obstetric outcome. ART increase the risk of adverse obstetric and perinatal outcome in the group < 40 years, but not in the group of women aged 40 years and older, probably due to the small size of the sample.     

Pronóstico perinatal y materno de las gestaciones gemelares concebidas mediante fecundación in vitro,en relación con las obtenidas espontáneamente

Objective

To determine the outcomes of twin pregnancies resulting from in vitro fertilization (IVF) compared with those resulting from spontaneous conception.

Material and methods

We performed a historical cohort study comparing neonatal outcomes of twin pregnancies resulting from IVF (n = 44) with those resulting from spontaneous conception (n = 109) in the Complejo Hospitalario Universitario de Albacete (Spain) in 2001, 2001 and 2003. The primary variable was perinatal mortality. Secondary variables were fetal morbidity (neonatal abnormalities, Apgar < 7, acidotic arterial pH, admission to the neonatal unit), preterm delivery, maternal complications, and type of delivery.

Results

No differences in perinatal mortality and morbidity were found between spontaneous twin pregnancies and twins resulting from assisted reproductive techniques. The rate of preterm labor was significantly higher in spontaneous twin pregnancies (75.2 versus 52%; p = 0.006). The incidence of gestational diabetes was significantly higher in twin pregnancies resulting from IVF than in spontaneous twin pregnancies (25.5 versus 9.7%;p = 0.01).

Conclusions

Perinatal and maternal outcomes in twin pregnancies resulting from IVF are similar to those of spontaneous twin pregnancies.     

Adecuación de la profilaxis antibiótica en el parto por cesárea

Objective

To evaluate compliance with a protocol for antibiotic prophylaxis in cesarean sections and its influence on the incidence of surgical wound infection.

Patients and methods

A prospective cohort study was carried out to assess compliance with our antibiotic prophylaxis protocol. Percentages of compliance and the cumulative incidence of infection were calculated. The effect of compliance with the protocol for antibiotic prophylaxis on surgical wound infection was estimated with the relative risk.

Results

We included 680 patients. Overall compliance with the protocol was 95.7%. The most frequent cause of lack of compliance was the time of administration (96.6%). The cumulative incidence of infection was 2.5% and there was no association between compliance with the protocol and the infection rate (RR = 4.5; 95% CI: 0.55-38.4; P>.05).

Conclusions

Compliance with the protocol for antibiotic prophylaxis was high. The cumulative incidence of surgical wound infection was low and was unrelated to antibiotic prophylaxis.     

Análisis de la relación entre riesgo gestacional y ansiedad materna

Objective

To evaluate levels of maternal anxiety in third trimester pregnancies according to pregnancy risk, classified as low, medium and high-risk/very high-risk.

Patients and methods

We performed an observational, analytical and cross-sectional study of anxiety levels in 174 pregnant women followed-up in our hospital. Levels of both state anxiety and trait anxiety were evaluated in the three groups of pregnant women.

Results

Of the 174 participants in the study, 98 (56.3%) had low risk pregnancies, 40 showed medium risk (23%) and 36 (20.7%) had high risk or very high risk pregnancies. We obtained a mean of 32.8 points for state anxiety and of 27.3 points for trait anxiety. Mean anxiety levels scores were 44.1 points in the high/very high risk group, 33 points in the medium risk group, and 28.5 points in the low risk group, with statistically significant differences (P = .0001 for the high risk group and P = .038 for the medium risk pregnancies). A significant correlation was found between trait anxiety and state anxiety (P = .0001). Statistically significant differences were observed in anxiety related to the number of children (P = .0001).

Conclusions

In pregnant women, anxiety levels were higher than average levels in the general population. Anxiety levels increased in accordance with greater risk in the pregnancy. The greater the number of children the mother already had the lower her anxiety level.     

Estudio de la integridad del ADN espermático en relación con la calidad seminal y los resultados del ciclo de fecundación in vitro

Objective

To establish the relationship between the degree of sperm DNA fragmentation and seminal parameters, male age and outcome of in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI).

Subjects and methods

The sample consisted of 43 couples undergoing IVF/ICSI. The mean age of men was 35.62 ± 4.87 years and that of women was 33.88 ± 3.95 years. We prospectively analyzed sperm DNA fragmentation from each patient by the Sperm Chromatin Structure Assay (SCSA) and correlated the findings with seminal parameters (volume, concentration, progressive motility and morphology), IVF/ICSI outcomes and male age. IVF/ICSI outcome was evaluated by measuring the fertilization rate, embryo quality and the pregnancy and miscarriage rates.

Results

DNA fragmentation was negatively correlated with progressive motility (p = 0.000) of fresh and capacitated (p = 0.041) semen. Older patients had a significantly lower percentage of progressive motility in fresh seminal samples (p = 0.034) and worse sperm DNA quality (p = 0.043). There were no significant differences between the fragmentation rate and fertilization rate, embryo quality, and the pregnancy and miscarriage rates.

Conclusions

DNA fragmentation is inversely correlated with progressive motility in fresh seminal samples. DNA fragmentation does not predict the IVF/ICSI outcome but screening for sperm DNA damage may provide useful information in the diagnosis of idiopathic male infertility. Seminal quality is affected by increasing male age.     

Relación entre los valores de hemoglobina materna anteparto y los resultados perinatales

Objective

To evaluate the association between maternal hemoglobin levels and perinatal outcomes.

Subjects and methods

Seven hundred twenty-eight pregnant women attended in the Hospital Universitario de Canarias, Tenerife (Spain) between January and April 2004 were studied. The women were divided into three groups: women with anemia (n = 61), women with normal hemoglobin levels (n = 587) and those with hemoconcentration (n = 80).An observational retrospective study was performed. Perinatal outcomes were compared among the groups studied and the possible correlations among hemoglobin levels and perinatal variables were analyzed.

Results

A significant quadratic relationship was found between maternal hemoglobin levels and both gestational age at delivery and birthweight. Multiple regression analysis showed that these variables were independent predictors of maternal hemoglobin concentration.

Conclusions

Gestational age at delivery and birthweight were lower in both the anemia and hemoconcentration groups. Maternal anemia is associated with a higher risk of having a small-forgestational- age neonate regardless of the risk of preterm delivery.     

Recuperación del parto vaginal de nalgas y versión cefálica externa

Objective

To review the obstetric and neonatal outcomes of the application of an updated vaginal breech delivery protocol 10 years after this practice had been discontinued.

Methods

Breech presentations were referred to a dedicated breech unit at 36 weeks where the external cephalic version was offered. If breech presentation persisted, the patients were selected to undergo attempted vaginal delivery if the following criteria were met: a) estimated fetal weight of 2.500-3.600 g; b) frank or complete breech presentation; c) absence of hyperextension of the fetal head; and d) a clinically adequate pelvis. Intrapartum criteria included: a) progression of labor of ≥ 1 cm/hour in the first hour; b) In the second stage, 90 minutes were allowed for adequate descent of the breech, and 1 hour of active pushing, and c) the availability of an on-call expert.

Results

A total of 93 patients showed single live pregnancies in breech presentation after external cephalic version. Sixty-nine patients (73.4%) underwent elective prelabor cesarean delivery, and 24 (26.6%) progressed to attempted vaginal breech delivery, which was successful in 19 (20.1%). Cesarean indications for breech presentation were reduced from 5.7% in 2009 to 2.02% after the application of external cephalic version and vaginal breech delivery (P<.001). We observed no fetal deaths, no Apgar test at 5 minutes of less than 7, no umbilical artery pH of less than 7, and no fetal injuries.

Conclusions

. When antepartum and intrapartum criteria are met, vaginal breech delivery is safe. The availability of an on-call expert allows vaginal breech delivery to be safely performed. The combination of external cephalic version and vaginal breech delivery decreases the cesarean rate for breech presentation.     

Análisis de la finalización de la gestación y morbilidad materna en las gestaciones de 41 semanas

Objective

To evaluate the mode of delivery and maternal morbidity associated with pregnancies ending at 41 weeks.

Material and methods

We designed a retrospective cohort study. The mode of delivery and maternal complications of 230 pregnancies ending at 41 weeks were compared with those in 234 pregnancies ending between 37 and 40 weeks at the Miguel Servet University Hospital in 2005.

Results

Women delivering at 41 weeks had an increased risk of membrane sweep, unfavorable Bishop score at admission, induction and longer duration of labor. These increases were also seen in the rates of operative vaginal delivery (25.6 vs 17.6%, p < 0.001) and cesarean section (21.7 vs 8.5%, p < 0.001).

Conclusions

The rates of maternal peripartum complications increase as pregnancy reaches 41 weeks. Accurate investigation of these rates is important to determine the gestational age at which the risk of continuing the pregnancy outweighs the risk of labor induction.     

Epidemiología de las estrías gravídicas en España

Objective

To assess the influence of different factors on the presence of striae prior to pregnancy as well as the development of new lesions during and after pregnancy.

Subjects and methods

An observational epidemiologic study was carried out on the prevalence and incidence of striae gravidarum and stretch marks in pregnant women. Data from 519 pregnant women were registered, including obstetric history, family history of striae gravidarum, weight prior to pregnancy, skin type, Fitzpatrick skin phototype, and current use of body creams and lotions. A multivariate analysis was used to determine the factors associated with the incidence of striae gravidarum during current pregnancy.

Results

The prevalence of pre-pregnancy stretch marks was 85.5%, mainly observed in patients with a first pregnancy (OR = 2.6), body mass index ≥ 25 (OR = 2.2), and family history of striae gravidarum (OR = 2.1). The overall incidence of striae gravidarum during pregnancy was 36.8% and most of these patients had a body mass index ≥ 25 (OR = 2.2) and were younger (< 30 years old; OR = 1.9). Risk analysis of all the variables registered indicated a higher risk of striae gravidarum in women who were overweight prior to pregnancy (OR = 1.8), those aged under 30 years (OR = 2.4), and those with previous pregnancies (OR = 4.3).

Conclusions

Prevention of striae gravidarum should be recommended in all cases, with special emphasis on younger women and those who are overweight or obese due to their higher risk for the development of these marks during pregnancy.     

Histerectomía radical laparoscópica total en el cáncer de cérvix. Factibilidad,morbilidad y supervivencia

Objective

To assess feasibility, perioperative morbidity and medium term survival of total laparoscopic radical hysterectomy in cervical cancer.

Material and methods

A total of 31 consecutive patients diagnosed FIGO clinical stage IA2 (n = 4), IB1 (n = 22), IIA (n = 2) and IB2 (n = 3) in Son Llàtzer hospital (Palma de Mallorca) that were programmed for a total laparoscopic radical hysterectomy were studied. We analyzed tumor histological characteristics, surgical technique, perioperative variables, postoperative complications and mid-term survival results.

Results

Feasibility rate was 96%. The most frequently operative complication was accidental bladder incision (3 cases). Postoperative complications rate was 20% (6 cases) which includes one surgical reintervention. Average operative time was 258 minutes (range: 180-360). Blood transfusion rate was 17% (n = 5) and mean hospital stay was 7.8 days (range: 2-29). After one month after surgery 72% of patients had a normal miccional function. Mean tumoral size was 26.5 mm and lymphatic positive nodes rate was 17% (n = 5). Mean follow-up time was 26 months. Tumor relapse rate was 17% (n = 5) and survival-free disease of 100% for IA2 stage, 82.6% of IB1/IIA stages and 66.7% for IB2 stage.

Conclusions

Total laparoscopic radical hysterectomy is a feasible technique in most of the patients with cervical cancer. It needs more operative time than abdominal route but it presents less perioperative morbidity, less blood transfusion and less ospitalization days. The medium term survival is comparable with conventional abdominal route.     

Factores pronóstico en la supervivencia del cáncer epitelial de ovario invasivo en el área sanitaria de León

Objective

We studied survival and associated prognostic factors in invasive epithelial ovarian cancer in women from the health area of León between 1991 and 2001.

Subjects and method

There were 236 patients with a histological diagnosis of invasive epithelial ovarian cancer, but only 221 were included in the survival study due to losses to follow-up. Univariate analysis of overall survival was performed and the distinct clinical factors were compared by means of the Log-Rank test or the Mantle-Haenszel test. Variables that were significant (p < 0.05) in univariate analysis were submitted to multivariate analysis using Cox multiple regression and variables that remained significant in this analysis were considered to be predictive factors of the disease.

Results

The over all survival at 1, 5 and 10 years was 69.1%, 37.9% and 24.7%, respectively. The variables modifying survival were FIGO stage (p ≤ 0.001), histological type (p ≤ 0.001), age at diagnosis (p ≤ 0.001), hormonal status (p ≤ 0.001), serum CA-125 marker (p = 0.034), degree of tumor differentiation (p = 0.004), type of primary surgery carried out (p ≤ 0.001), type of chemotherapy administered (p ≤ 0.001), and disease recurrence (p = 0.054). Variables that remained significant after Cox regression were FIGO stage (p = 0.002), histological type(p = 0.008), and age at diagnosis (p = 0.004). For stage I and II tumors, the only variable thatmodified prognosis was disease recurrence (p ≤ 0.001). For advanced tumoral stages (III and IV), significant variables in the univariate analysis were age (p = 0.001), histological type(p = 0.023), hormonal status (p = 0.036), serum CA-125 marker (p ≤ 0.001), the type of primary surgery performed (p < 0.001), type of chemotherapy administered (p ≤ 0.001), and disease recurrence (p ≤ 0.001). The variables that remained significant after multivariate analysis were histological type (p = 0.006) and the type of surgery performed (p = 0.037).

Conclusions

In our study, the prognostic factors that modified survival in patients with invasive epithelial ovarian cancer in the health area of León were tumoral stage, age, and histological type.     

Near-miss o casi pérdida en un hospital de referencia

Objectives

To analyze maternal health from direct mortality and the concept of near-miss at La Fe University Hospital in Valencia (Spain) from 1991 to 2007.

Material and methods

We calculated the direct maternal mortality ratio (DMMR) from 1971-2007 and the severe obstetric morbility-mortality ratio from 1991-2007, and analyzed their causes.

Results

A significant DMMR decrease (rho = - 1), with a significant reduction in mortality due to cardiovascular disease was found. When analyzing severe maternal morbidity, we observed an increase of placenta previa (OR = 1.79), abruptio placentae (OR = 1.35), uterine rupture (OR = 2.48) and anesthetic complications (OR = 6.20), with a significant decrease of postpartum hemorrhage (OR = 0.63) and severe puerperal infection (OR = 0.32).The prevalence of hypertensive disorders of pregnancy, thromboembolic disease, intrauterine fetal death and severe morbidity/mortality ratio remained stable during the study period.

Conclusions

Estimating the severe obstetric morbidity-mortality ratio due to different near-miss definitions in the literature is difficult. The DMMR decreased, while the morbidity/mortality ratio remained stable.     

Bandas suburetrales libres de tensión transobturatriz in-out: indicación y resultados asociados

Objective

To describe the characteristics of treated patients and assess the results obtained.

Subjects and methods

All patients (n = 162) who underwent this technique between June 2005 and December 2010 at the Hospital de Fuenlabrada were included.

Results

The mean age was 51.64 years, mean body max index was 28.92 kg/m² and the mean number of vaginal deliveries was 2.31. Urodynamic diagnosis was performed in 96.3%, with findings of pure stress incontinence in 68.5%, mixed incontinence and stress incontinence in 25.9%. Intraoperative complications occurred in 3.1%. Mesh erosions were found in 1.2%. The overall objective cure rate was 92% and the subjective cure rate was 80.3%.

Conclusions

The complications rate was low and all complications were resolved. Cure rates were highly satisfactory both in pure stress urinary incontinence and in mixed urinary incontinence with a predominance of stress incontinence. Urodynamic studies before surgery allow good surgical indications and guide postsurgical prognosis.     

Comparación de la efectividad de la pulsioximetría y el electrocardiograma fetal en las situaciones de riesgo de pérdida de bienestar fetal

Objective

To evaluate the effectiveness of pulse oximetry and fetal electrocardiogram in the management of labor with fetal heart rate patterns associated with a risk of loss of fetal well-being.

Subjects and methods

We performed an open, randomized, experimental trial with two groups: pulse oximetry was used in one group and the STAN® technique was used in the other. Each group included 40 women with single, term pregnancies in cephalic presentation and fetal heart rate patterns associated with a risk of loss of fetal well-being. The overall cesarean section rate, indications of risk of fetal distress, and neonatal acid-base balance were evaluated.

Results

No significant differences were found in the rate of cesarean section (47.5 vs 40%; P = .33), indications of risk of fetal distress (32.5 vs 37.5%; P = .41), or neonatal outcomes.

Conclusions

The use of pulse oximetry and STAN®21, as auxiliary methods to cardiotocographic recording, showed no superiority in reducing the cesarean section rate or improving neonatal outcomes.     

Idoneidad de las indicaciones de cesárea. Una aplicación en la gestión de la práctica clínica

Objectives

To describe the quality management system applied by the Obstetrics and Gynecology Service of the Manacor Hospital, Majorca (Spain) to the process of cesarean section, and to assess the appropriateness of caesarean sections performed in this service between 2004 and 2005.

Subjects and methods

Consensus was reached on evidence-based indications for emergency and elective cesarean sections and on their quality criteria. All clinical records were reviewed to assess the appropriateness of cesarean sections performed from 2004-2005 according to previously established standards.

Results

In all two-monthly periods, appropriateness was achieved according to previously established standards (100% of elective interventions and > 90% of emergency cesarean sections), except in July-August, 2004 and May-June 2005 (appropriateness of elective cesarean sections = 92%), and in July-August 2004 (appropriateness of emergency interventions = 84%).

Conclusions

To reduce unjustified variability in clinical practice, cesarean section indications must be standardized, based on scientific evidence, and regularly assessed.
