Relation of cervical length at 22-24 weeks of gestation to demographic characteristics and obstetric history

Preterm delivery is the main cause of neonatal death and ultrasonographic cervical assessment has been shown to be more accurate than digital examination in recognizing a short cervix. This is a cross-sectional study, involving 1131 women at 22-24 weeks of pregnancy, designed to determine the distribution of cervical length and to examine which variables of demographic characteristics and obstetric history increase the risk of a short cervix (15 mm or less). The distribution of maternal demographic and obstetric history characteristics among patients with cervical length £15 mm was analyzed and compared to the findings for the general population. Risk ratios (RR) between subgroups were generated from this comparison. Median cervical length was 37 mm and in 1.5% of cases it was 15 mm or less. The proportion of women with a short cervix (<=15 mm) was significantly higher among patients with a low body mass index (RR = 3.5) and in those with previous fetal losses between 16-23 weeks (RR = 33.1) or spontaneous preterm deliveries between 24-32 weeks (RR = 14.1). We suggest that transvaginal sonographic measurement of cervical length be performed as part of a routine midtrimester ultrasound evaluation. There are specific variables of demographic characteristics and obstetric history which increase the risk of detecting a short cervix at 22-24 weeks.

Markers of insulin resistance and sedentary lifestyle are predictors of preeclampsia in women with adverse obstetric results

Some thrombophilias and severe preeclampsia may increase the risk for preterm deliveries and fetal death due to placental insufficiency. Our objective was to evaluate clinical and laboratory data as predictors of preeclampsia in a population of mothers with 3rd trimester fetal losses or preterm deliveries. In a longitudinal retrospective study, 54 consecutive women (age range: 16 to 39 years) with normotensive pregnancies were compared to 79 consecutive women with preeclampsia (age range: 16 to 43 years). Weight accrual rate (WAR) was arbitrarily defined as weight gain from age 18 years to the beginning of pregnancy divided by elapsed years. Independent predictors of preeclampsia were past history of oligomenorrhea, WAR >0.8 kg/years, pre-pregnancy or 1st trimester triglyceridemia >150 mg/dL, and elevated acanthosis nigricans in the neck. In a multivariate logistic regression model, two or more predictors conferred an odds ratio of 15 (95%CI [5.9-37]; P < 0.001) to develop preeclampsia (85% specificity, 73% sensitivity, c-statistic of 81 ± 4%; P < 0.0001). Clinical markers related to insulin resistance and sedentary lifestyles are strong independent predictors of preeclampsia in mothers with 3rd trimester fetal losses or preterm deliveries due to placental insufficiency. Women at risk for preeclampsia in this particular population might benefit from measures focused on overcoming insulin resistance.

Etude qualitative sur les causes du premier retard et leur impact sur la morbidité des urgences obstétricales. Le cas des échappées belles du District de Diema (Mali).

L’accouchement et ses conséquences demeurent une des principales causes d’incapacité et de décès pour les femmes dans les pays en développement et comprendre l’utilisation tardive des soins obstétricaux d’urgence au moment d’une complication obstétricale constitue un véritable défi en santé publique. La présente étude qualitative relate l’expérience d’accouchement difficile au Mali, en milieu rural. Dans un contexte de pluralité de systèmes de soins, l’objet de cette étude consiste à déterminer les raisons de l’arrivée tardive des femmes au centre de santé de 1ier ligne, à saisir la compréhension qu’elles ont de l’utilisation des services sanitaires, enfin à reconstruire les processus de prise de décisions de recourir aux soins modernes. Cette étude s’inscrit dans une démarche de type ethnographique. Des entretiens semi dirigés et l’observation des interactions entre les femmes et les professionnels de santé ont constitué le corpus de données. Nous retenons qu’une série de facteurs entrent en jeu pour comprendre le problème de l’utilisation tardive des soins obstétricaux d’urgence. Des contraintes exogènes liées à la distance et l’immédiateté de l’urgence obstétricale c'est-à-dire la mobilisation des ressources et des moyens de transport, accompagnées de contraintes endogènes telles que la subordination des femmes au consentement familial, la perception de la qualité des soins et de la compétence des soignants, influencent systématiquement le choix de recourir aux soins modernes. Le phénomène de gestion collective de la complication obstétricale s’inscrit dans un contexte d’intéractions complexes où l’opinion des femmes est totalement minimisée.

Complicaciones de la preeclampsia severa y su relación con variables demográficas y obstétricas

Introducción: La preeclampsia severa es una de las principales patologías que afectan a las mujeres embarazadas, sus complicaciones tienen un alto impacto en la salud del binomio madre-hijo. Materiales y métodos: Se realizo una serie de casos, durante un periodo de 1 año se revisaron las historias clínicas de las pacientes que ingresaron a la unidad de cuidado intensivo obstétrico de la Clínica Orquídeas, con diagnóstico de preeclampsia severa. Se describieron los datos demográficos y las complicaciones. Se realizó análisis univariado con las variables de interés y se calcularon diferencias significativas por medio del test exacto de Fisher. Resultados: Se registraron 196 pacientes con preeclampsia severa en el periodo de estudio. Las complicaciones mas frecuentes fueron síndrome HELLP (30,6%), insuficiencia renal aguda (16,3%) y edema pulmonar (10,2%); el ingreso de las pacientes con preeclampsia severa a la UCIO en embarazo aumenta el riesgo de sufrir complicaciones. El síndrome de HELLP se presento con mayor frecuencia en pacientes que realizaron 6 o mas controles prenatales (p=0.066). Discusión: Los resultados evidencian una prevalencia de preeclampsia severa mayor que la observada por otros autores, probablemente por ser una UCI exclusivamente obstétrica. Las complicaciones mas frecuentes son concordantes con otros estudios publicados. El mayor riesgo de complicaciones asociadas en pacientes que ingresan embarazadas a la UCIO podría estar en relación a la severidad de la patología. Se requieren estudios analíticos para establecer asociaciones entre cada una de las complicaciones y sus factores condicionantes.

Granskning av riktlinjer vid Sveriges förlossningskliniker gällande sfinkterskada i samband med förlossning : Innehållsanalys med en kombination av en deduktiv och induktiv ansats

Background: Sphincter injury is serious complication in connection to vaginal childbirth. Desire to avoid vaginal birth again is seen in women who previously suffered from a sphincter injury. Objective: To identify and evaluate obstetric guidelines in Sweden regarding sphincter injury in relation to childbirth Method: Content analysis with a combination of a deductive and inductive approach. Results: The most frequently occurring risk factors and prevention with help of perineal protection were described in the guidelines. The physician made diagnosis and repaired the sphincter injury at the theatre.  Complications such as coital pain and anal incontinence were described in the guidelines. Paracetamol and diclofenac was most common analgesic regimen given for pain. Prophylaxis such as antibiotic treatment and laxative were common. Information given to women was described. Follow-up by physician, midwife and physiotherapist was recommended after four weeks to six months. For future birth a cesarean section was recommended. Conclusion: The guidelines were constructed in the same way and had to a large extent similar content. The authors of the present work recommend a national guideline.

Síndrome metabólica e fatores associados: estudo comparativo com mulheres que apresentaram pré-eclâmpsia e gravidez normal, acompanhadas cinco anos após o parto

Preeclampsia is defined as an extremely serious complication of the pregnancy-puerperium cycle with delayed emergence of cardiovascular risk factors, including metabolic syndrome. The research aimed estimate the prevalences of metabolic syndrome and associated factors in women with preeclampsia and normal pregnancy followed five years after childbirth. This is a cross-sectional observational study using a quantitative approach, conducted at a maternity school in the city of Natal in Rio Grande do Norte state. The sample was composed of 70 women with previous preeclampsia and 75 normal selected by simple random probability sampling. Subjects were analyzed for sociodemographic, obstetric, clinical, anthropometric and biochemical parameters. International Diabetes Federation criteria were adopted to diagnose metabol ic syndrome. The Kolmogorov-Smirnov, Mann-Whitney, Student s t, Pearson s chi-squared, and Fisher s exact tests, in addition to simple logistic regression, were used for data analysis, at a 5% significance level (p ≤ 0.05). Statistical tests demonstrated elevated body mass index (p = 0.001), predominance of family history of diabetes mellitus (p = 0.022) and significantly higher prevalence of metabolic syndrome in the preeclampsia group (37.1%) when compared to normal (22.7%) (p = 0.042). Intergroup comparison showed a high number of metabolic syndrome components in women with previous preeclampsia. Altered systolic and diastolic blood pressure (p < 0.001) was the most prevalent, followed by low concentrations of high-density lipoproteins (p = 0.049), and hyperglycemia (p=0.030). There was a predominance of the metabolic syndrome in women with schooling 0-9 years (42.4%) (p = 0.005), body mass index above 30Kg.m 2 (52.3%) (p < 0.001), uric acid high (62.5%) (p = 0.050 and family history of hypertension (38.5%) (p< 0.001). Multivariate analysis of the data showed that the body mass index above 30 kg.m2, education level less than 10 years of study (p < 0.001) and family history of hypertension (p = 0.002) remained associated with the metabolic syndrome after multivariate analysis of the data. It is considered Women with previous preeclampsia exhibited high prevalence of metabolic syndrome and their individual components in relation to normal, especially, altered systolic and diastolic blood pressure, low concentrations of high-density lipoproteins and hyperglycemia. The factors associated to this ou tcome were obesity, less than 10 years of schooling, and family history of hypertension. Overall, this study identified young women with a history of PE exposed to a higher cardiovascular risk than normal

Atuação do enfermeiro na rede básica de saúde frente a gestante com infecção do trato urinário

The Urinary Tract Infection (UTI) in pregnancy is important as a consequence of the high incidence during the gestation. It is the third most common clinical complication in pregnancy affecting 10-12% of women whether prevalence is increasing in the first trimester of pregnancy, it may also contribute to maternal and infant mortality. Due the relevance for the results of obstetric and neonatal complications from UTI, these complications must be prevented, because it can lead to health hazards to pregnant women and newborns, producing a direct effect on morbidity and perinatal mortality. On this basis, it was defined as objectives of this research the identification of the profile of nurses from the Family Health Strategy (FHS) in the East and West Health Districts from the city of Natal / RN before the women with UTI and to verify the nurse performance during prenatal consultations. This is an exploratory study with a quantitative approach using a sample of 40 nurses active workers during this survey, it was approved by the Research Ethics Committee of the Universidade Federal do Rio Grande do Norte Protocol n0 232/10 P-CEP/UFRN and opinion n0 080/2011. The tool for data collection was a structured interview. The data collected were organized into an electronic database application Microsoft ® Excel 2007, exported and analyzed using the Statistical Package for Social Sciences (SPSS) version 17.0, and coded, tabulated and presented through tables and charts into their respective percentage distributions, using the descriptive and inferential statistical analysis, chi-square test and significance level of 5% (distribution in relative and absolute frequencies) in the independent variables. Therefore, it was observed from these results that the longer action of nurses in the FHS from the East and Weast health districts of the city of Natal/RN contributed to the development of a greater number of activities to control the incidence of UTI in women who are attended in the prenatal care service, proven by significance in statistics

The hemolytic uremic syndrome as a complication of adriamycin nephropathy

Rats treated with two injections of adriamycin (week 0 and week 12) developed glomerusclerosis and severe tubulointerstitial lesions as described in the literature. In addition, a number of glomerular alterations were present. These included capillary loop dilation, insudation of eosinophilic material, necrosis, duplication of the glomerular basement membrane, severe mesangiolysis with disruption of the mesangial matrix and segmental double- contours. The renal arterioles and interlobular arteries showed endothelial cell swelling. The subendothelial space was infiltrated by fibrinoid material and there was intensive fibrinoid necrosis of the wall of both arteries and arterioles extending into the glomerular tuft. These alterations were very similar to those observed in the hemolytic uremic syndrome. This observation suggests that the two injections of adriamycin, with a long interval in between them, might induce renal lesions similar to those observed in the hemolytic uremic syndrome.

Brazilian network for the surveillance of maternal potentially life threatening morbidity and maternal near-miss and a multidimensional evaluation of their long term consequences

Background. It has been suggested that the study of women who survive life-threatening complications related to pregnancy (maternal near-miss cases) may represent a practical alternative to surveillance of maternal morbidity/mortality since the number of cases is higher and the woman herself is able to provide information on the difficulties she faced and the long-term repercussions of the event. These repercussions, which may include sexual dysfunction, postpartum depression and posttraumatic stress disorder, may persist for prolonged periods of time, affecting women's quality of life and resulting in adverse effects to them and their babies. Objective. The aims of the present study are to create a nationwide network of scientific cooperation to carry out surveillance and estimate the frequency of maternal near-miss cases, to perform a multicenter investigation into the quality of care for women with severe complications of pregnancy, and to carry out a multidimensional evaluation of these women up to six months. Methods/Design. This project has two components: a multicenter, cross-sectional study to be implemented in 27 referral obstetric units in different geographical regions of Brazil, and a concurrent cohort study of multidimensional analysis. Over 12 months, investigators will perform prospective surveillance to identify all maternal complications. The population of the cross-sectional component will consist of all women surviving potentially life-threatening conditions (severe maternal complications) or life-threatening conditions (the maternal near miss criteria) and maternal deaths according to the new WHO definition and criteria. Data analysis will be performed in case subgroups according to the moment of occurrence and determining cause. Frequencies of near-miss and other severe maternal morbidity and the association between organ dysfunction and maternal death will be estimated. A proportion of cases identified in the cross-sectional study will comprise the cohort of women for the multidimensional analysis. Various aspects of the lives of women surviving severe maternal complications will be evaluated 3 and 6 months after the event and compared to a group of women who suffered no severe complications in pregnancy. Previously validated questionnaires will be used in the interviews to assess reproductive function, posttraumatic stress, functional capacity, quality of life, sexual function, postpartum depression and infant development. © 2009 Cecatti et al.
