Public health impact of Infanrix hexa (DTPa-HBV-IPV/Hib) reimbursement: A study programme in France. Part 1: Evolution of hepatitis B vaccine coverage rates in infants aged less than 27 months, in the general population - the PopCorn study.

BACKGROUND: Reimbursement of the hexavalent vaccine (Infanrix hexa) comprising the DTPa-IPV-Hib components and the hepatitis B valence in a single vaccine was decided in March 2008 in France. The impact of its reimbursement on the hepatitis B vaccine coverage rate was assessed in a study conducted in the general population prior to and after implementation of the reimbursement policy. METHODS: The PopCorn study (NCT01782794) was a national, cross-sectional and repeated study, with four assessment periods over 3 years, from 2009 to 2012, to assess the hepatitis B vaccine coverage in 12- to 15- and 24- to 27-month-old children, vaccinated between 2007 and 2011 and selected by the quota sampling method. Face-to-face interviews were conducted at their homes and vaccination status was collected using their child's health record. Parents were also interviewed on their perceptions and acceptance of hepatitis B vaccination. Three indicators were calculated to assess hepatitis B vaccination coverage: proportions of infants with at least one dose before 6 months of age, with at least two doses before 6 months of age and with a complete schedule at 24 months of age. RESULTS: A total of 4903 children were enrolled in the study. An overall significant increase (P-value [P<0.05]) of the three indicators of interest over the four periods of time was observed for both age groups. The proportion of children receiving hepatitis B vaccination before 6 months increased from 21% at baseline (before vaccine reimbursement) to almost 75% at the last assessment period in 2012. More than 60% of 24- to 27-month-old children received a complete schedule in 2012 compared to 33% at baseline. No significant increases in the proportions of parents "favourable" and "moderately in favour" of hepatitis B vaccination were observed across the four evaluation periods (respectively, 17-22% and 48-50%, P=0.09). CONCLUSION: The rapid increase of hepatitis B vaccination coverage suggests a significant change in hepatitis B vaccination practice related to the hexavalent vaccine's reimbursement. This change was observed in a context of stability regarding parents' perceptions and acceptance of hepatitis B vaccination and of coverage rates for other infant vaccinations.

Public health impact of Infanrix hexa™ (DTPa-HBV-IPV/Hib) reimbursement: A study programme in France. Part 2: Evolution of the acceptability of infants' vaccination against hepatitis B in general and pediatric practices - the PRALINE study.

BACKGROUND: The reimbursement of the hexavalent vaccine (Infanrix hexa™), comprising the DTPa-IPV-Hib components and the hepatitis B recombinant in a single vaccine, was approved in France in March of 2008. The impact of its reimbursement on physicians' decisions to vaccinate infants against hepatitis B was assessed in a study conducted with general practitioners and pediatricians. METHODS: The PRALINE study (NCT01777074) was a national, cross-sectional, repeated study with two measurement periods (T1 and T2) that measured the changes in physicians' acceptance of hepatitis B vaccination of infants before and for the 3 years after the approval of the hexavalent vaccine reimbursement. Two patient registers were created for each measurement period to enroll the first 15 12- to 15-month-old infants and the first 15 24- to 27-month-old children seen by the practitioners. The proportion of eligible children receiving a hepatitis B vaccine for each physician's practice was calculated. Practitioners also answered a vaccination practice questionnaire via telephone interviews. RESULTS: Across the two study periods, 418 general practitioners and 463 pediatricians were recruited and responded to the telephone interview on their vaccination practices. The overall number of children included in the study in both study periods reached almost 20,000. In the general practitioners group, there was a significant increase in the proportion of physicians "practicing hepatitis B vaccination" (i.e., at least 50% of eligible children receiving the initial hepatitis B vaccination) in children 24-27 months old (79% T2 versus 47% T1, P-value [P]<0.001). Similarly, the proportion of pediatricians initiating hepatitis B vaccination increased from 51% (T1) to 94% (T2) (P<0.0001). General practitioners offered hepatitis B vaccination to infants more systematically in the second study period (87% T2 versus 73% T1, P<0.001) and also suggested the use of the hexavalent vaccine to more patients after reimbursement (92% T2 versus 78% T1, P<0.0001). The proportion of pediatricians offering vaccination to every infant was high at T1 (94%) and remained steady (97%) with a high use of the hexavalent vaccine (94% T1 and 96% T2). CONCLUSION: The PRALINE study shows a significant and immediate change in the hepatitis B vaccination practices of general practitioners and pediatricians following hexavalent vaccine reimbursement with a significant increase in hepatitis B vaccine coverage in infants.

[Perceived morbidity and community burden of chikungunya in La Reunion]. / Morbidité perçue et impact communautaire du chikungunya a l'île de La Réunion: enquête de cohorte en population TELECHIK.

BACKGROUND: Persistence of clinical manifestations, especially polyarthralgia and fatigue, is a characteristic feature of chikungunya virus (CHIK-v) infection. The purpose of this study was to measure the impact of prolonged or late-onset manifestations of CHIK-v infection on the self-perceived health of people on Reunion Island. METHODS: This retrospective cohort survey, dubbed TELECHIK survey, was conducted eighteen months after the end of the chikungunya outbreak on a representative random sample from the SEROCHIK population-based survey conducted on Reunion Island. A total of 1094 subjects whose CHIK-v specific IgG antibody status had been documented were interviewed about current symptoms. RESULTS: Analysis of data showed 45% of CHIK+ vs 14% of CHIK- subjects reporting musculoskeletal pain (P < 0.001), 56% vs. 44% reporting fatigue (P = 0.003), 77% vs. 53% reporting cerebral manifestations (P < 0.001), 51% vs. 34% reporting sensorineural impairments (P < 0.001), 18% vs. 13% reporting digestive complaints (P = 0.06), and 38% vs. 32% reporting skin involvement (P = 0.13). The mean delay between infection and interview was two years (range, 15-34 months). Analysis of data after correction for age, gender, body mass index and comorbidity indicated that rheumatic pain, fatigue, cerebral manifestations and sensorineural impairments were more likely in CHIK+ than CHIK- subjects but the likelihood of digestive and skin manifestations was the same. CONCLUSION: With a mean delay of two years after infection, 45% to 77% of CHIK+ subjects reported prolonged or late-onset symptoms attributable to CHIK-v. These results indicate that persistent manifestations of chikungunya infection have a heavy impact on rheumatologic, neurological and sensorineural health.

Osteoporosis and venous thromboembolism: a retrospective cohort study in the UK General Practice Research Database.

UNLABELLED: In a retrospective cohort study using the General Practice Research Database (GPRD), there was a greater association of venous thromboembolism (VTE) in osteoporotic than in non-osteoporotic female patients. No greater association was shown in treated patients with strontium ranelate or alendronate compared to untreated osteoporotic female patients. INTRODUCTION: We explored the risk of VTE in usual practice in osteoporotic and non-osteoporotic women with and without anti-osteoporotic treatment. METHODS: A retrospective study was conducted using the GPRD in the UK. The cohorts consisted of untreated osteoporotic women (N = 11,546), osteoporotic women treated with alendronate (N = 20,084), or strontium ranelate (N = 2,408), and a sample of non-osteoporotic women (N = 115,009). Cohorts were compared using a Cox proportional hazards regression model. RESULTS: There was a significantly increased relative risk for VTE in untreated osteoporotic women versus non-osteoporotic women (annual incidence 5.6 and 3.2 per 1,000 patient-years, respectively; relative risk 1.75 [95% confidence interval (CI), 1.09-1.84]). Results were confirmed using adjusted models. The annual incidences of VTE in osteoporotic patients treated with strontium ranelate and alendronate were 7.0 and 7.2 per 1,000 patient-years, respectively, with no significant difference between untreated and treated patients whatever the treatment. Adjusted hazard ratios for treated versus untreated osteoporotic women were 1.09 (95% CI, 0.60-2.01) for strontium ranelate and 0.92 (95% CI, 0.63-1.33) for alendronate. CONCLUSION: This study shows a greater association of VTE in osteoporotic compared to non-osteoporotic patients, but does not show any greater association in treated patients with strontium ranelate or alendronate compared to untreated osteoporotic patients.

[The eastern Paris perinatal network (2008-2010). Defining the target population and assessing health needs]. / Le réseau périnatal de l'Est parisien (2008-2010). Définition de la population concernée pour évaluer les besoins à couvrir par le réseau.

BACKGROUND: Since the 1990s, governmental plans in France have imposed the regionalization of perinatal care to improve both safety and quality of care. The Eastern Paris Perinatal Network is under construction in health area 75-2, which includes the 11th, 12th, 13th and 20th arrondissements of Paris. A major issue is ensuring that the network can meet the needs of its target population. The objective is to define the network's target population of mothers and newborns. METHODS: We designed a matrix to help assess these needs and identify the data required to define the network's population. Four principal data sources were analyzed: the National Statistics and Economic Studies Institute (Insee) data, annual health facility activity data, national medical informatics program data, and 8th-day health certificates. RESULTS: The network's target population varies according to the precise perinatal period and the planning stage. For the conception period, it includes the general population and specifically all women of childbearing age (15-49 years). The health area included 672,000 inhabitants in 2006, 29% of them are women of childbearing age. The proportion of people born outside France and who are of foreign nationality ranges, according to arrondissement, from 13.2 to 20.0%; the mean for the Paris metropolitan area is 14.7%. Approximately 16,500 women gave birth in 2007, at nine obstetric facility sites in the health area (five level I, three level II, and one type III); only 41.46% of them resided in the health area. Approximately 2500 women living in the health area gave birth at a facility outside the area. The population likely to be covered by the network is thus estimated at approximately 19,000 women. CONCLUSION: A network must simultaneously take into account the local resident population and the population using its health care system. In an urban area such as Paris, where the health care supply is dense, it is essential for policy planning process to define the contours of the target population of a health network.

[Propositions for perinatal care at extremely low gestational ages - Working group on "Extremely low gestational ages" for SFMP, CNGOF, and SFN]. / Propositions sur la prise en charge en cas d'extrême prématurité ­ Le groupe de travail « Extrême Prématurité ¼ pour la SFMP, le CNGOF et la SFN.

OBJECTIVES: International literature suggests that active perinatal management at extremely low gestational ages improves survival without increasing the risk of impairment in survivors, compared to less active management. Although these results are limited to a small number of countries, they question current practices in France. New propositions on perinatal management of extremely preterm infants have carried out by the French Society of Perinatal Medicine, the French Society of Neonatology and the National College of French Obstetricians and Gynecologists. METHODS: This group was set up in 2015 on the initiative of the professional societies and in collaboration with parents' and users' associations. The work was based on a review of the literature on the prognosis of extremely preterm children, as well as on recommendations by European societies. Based on this information, a text was produced, submitted to all members of the working group and definitively validated in April 2019. RESULTS: This text offers a decision-making guideline for the management at extremely low gestational ages. Its principles are: the administration of steroids independently of management (resuscitation or comfort care); a prognostic evaluation and a collegial decision, outside the context of the emergency; a consensus on the information to be given to parents before going to inform them and gather their opinion. CONCLUSIONS: These new propositions will contribute to modifying perinatal care at extremely low gestational ages in France.

Obstetric interventions for babies born before 28 weeks of gestation in Europe: results of the MOSAIC study.

OBJECTIVE: To describe obstetric intervention for extremely preterm births in ten European regions and assess its impact on mortality and short term morbidity. DESIGN: Prospective observational cohort study. SETTING: Ten regions from nine countries participating in the 'Models of Organising Access to Intensive Care for Very Preterm Babies in Europe' (MOSAIC) project. POPULATION: All births from 22 to 29 weeks of gestation (n = 4146) in 2003, excluding terminations of pregnancy. METHODS: Comparison of three obstetric interventions (antenatal corticosteroids, antenatal transfer and caesarean section for fetal indication) rates at 22-23, 24-25 and 26-27 weeks to that at 28-29 weeks and the association of the level of intervention with pregnancy outcome. MAIN OUTCOME MEASURES: Use of antenatal corticosteroids, antenatal transfer and caesarean section by two-week gestational age groups as well as a composite score of these three interventions. Outcomes included stillbirth, in-hospital mortality and intraventricular haemorrhage (IVH) grades III and IV and/or periventricular leucomalacia (PVL) and bronchopulmonary dysplasia (BPD). RESULTS: There were large differences between regions in interventions for births at 22-23 and 24-25 weeks. Differences were most pronounced at 24-25 weeks; in some regions these babies received the same care as babies of 28-29 weeks, whereas elsewhere levels of intervention were distinctly lower. Before 26 weeks and especially at 24-25 weeks, there was an association between the composite intervention score and mortality. No association was observed at 26-27 weeks. For survivors at 24-25 weeks, the intervention score was associated with higher rates of BPD, but not with IVH or PVL. CONCLUSIONS: There are large differences between European regions in obstetric practices at the lower limit of viability and these are related to outcome, especially at 24-25 weeks.

Comparison of fundal height measurement and sonographically measured fetal abdominal circumference in the prediction of high and low birth weight at term.

OBJECTIVES: To compare the diagnostic value of fundal height and sonographically measured fetal abdominal circumference in the prediction of high and low birth weight in routine practice between 37 and 41 weeks' gestation. METHODS: Data were obtained from a multicenter study of 19 415 women in France and Belgium. In this study we included 7138 low-risk women from that population who underwent fundal height measurements no more than 8 days before delivery (Population A). We also included another 1689 women with both fundal height measurements and fetal ultrasound measurements obtained no more than 8 days before delivery (Population B). Population A was used to calculate the parameters of equations for estimating fetal weight according to fundal height alone (EFW(FH)) or fundal height in combination with other clinical indicators (EFW(FH+)). The ultrasound fetal weight estimation was based on fetal abdominal circumference (EFW(AC)) using Campbell and Wilkins' equation. The correlation between the estimated fetal weight calculated using each of the formulae and the birth weight was then evaluated in Population B, and the diagnostic value of each of the methods for predicting birth weight or=4000 g was also compared. RESULTS: EFW(AC) was better correlated with birth weight than was either EFW(FH) or EFW(FH+). With specificity set at 95%, the sensitivity of EFW(AC) in screening for neonates weighing or=4000 g was significantly higher than that of EFW(FH) (54.0% vs. 37.1%, P < 0.05) or EFW(FH+) (54.0% vs. 45.1%, P < 0.05). CONCLUSIONS: Sonographic measurement of fetal abdominal circumference predicts high and low birth weight better than does clinical examination based on fundal height in routine practice between 37 and 41 weeks' gestation.

Termination of pregnancy among very preterm births and its impact on very preterm mortality: results from ten European population-based cohorts in the MOSAIC study.

OBJECTIVE: To study the impact of terminations of pregnancy (TOP) on very preterm mortality in Europe. DESIGN: European prospective population-based cohort study. SETTING: Ten regions from nine European countries participating in the MOSAIC (Models of OrganiSing Access to Intensive Care for very preterm babies) study. These regions had different policies on screening for congenital anomalies (CAs) and on pregnancy termination. POPULATION OR SAMPLE: Births 22-31 weeks gestational age. METHODS: The analysis compares the proportion of TOP among very preterm births and assesses differences in mortality between the regions. MAIN OUTCOME MEASURES: Pregnancy outcomes (termination, antepartum death, intrapartum death and live birth) and reasons for termination, presence of CAs and causes of death for stillbirths and live births in 2003. RESULTS: Pregnancy terminations constituted between 1 and 21.5% of all very preterm births and between 4 and 53% of stillbirths. Most terminations were for CAs, although some were for obstetric indications (severe pre-eclampsia, growth restriction, premature rupture of membranes). TOP contributed substantially to overall fetal mortality rates in the two regions with late second-trimester screening. There was no clear association between policies governing screening and pregnancy termination and the proportion of CAs among stillbirths and live births, except in Poland, where neonatal deaths associated with CAs were more frequent, reflecting restrictive pregnancy termination policies. CONCLUSION: Proportions of TOP among very preterm births varied widely between European regions. Information on terminations should be reported when very preterm live births and stillbirths are compared internationally since national policies related to screening for CAs and the legality and timing of medical terminations differ.

[Prevention and early management of immediate postpartum haemorrhage: policies in six perinatal networks in France]. / Politiques de prévention et de prise en charge précoce de l'hémorragie du post-partum immédiat dans six réseaux de maternités françaises.

OBJECTIVES: Postpartum haemorrhage (PPH) constitutes the leading cause of maternal deaths in France, and the majority of these deaths are preventable. The objective of this study was to ascertain policies for prevention and early management of PPH in maternity units, and to compare the results with scientific evidence. The survey was part of the Euphrates European project, and was conducted in France in 2003 before national recommendations for clinical practice related to PPH were launched. MATERIALS AND METHODS: A cross-sectional declarative survey was conducted in six perinatal networks representing 132 maternity units. A postal questionnaire was sent to all units. Main outcomes measured were stated policies for prevention, diagnosis and management of PPH. RESULTS: There was no definition of PPH in one out of four units, and no written protocol for PPH management in one out of six. Policies of using preventive uterotonics were widespread, but variation was observed concerning the timing of administration, and association with the other components of active management of the third stage of labour. Policies about drugs used for management of PPH also varied. CONCLUSION: Variations in policies show firstly that evidence-based improvement in practice is possible, and secondly that further research is needed on poorly documented aspects of PPH management.

Variation in rates of postterm birth in Europe: reality or artefact?

OBJECTIVE: To compare rates of postterm birth in Europe. DESIGN: Analysis of data from vital statistics, birth registers, and national birth samples collected for the PERISTAT project. SETTING: Thirteen European countries. POPULATION: All live births or representative samples of births for the year 2000 or most recent year available. METHODS: Comparison of national and regional rates of postterm birth. Other indicators (birthweight, deliveries with a non-spontaneous onset and mortality) were used to assess the validity of postterm rates. MAIN OUTCOME MEASURES: The proportion of births at 42 completed weeks of gestation or later. RESULTS: Postterm rates varied greatly, from 0.4% (Austria, Belgium) to over 7% (Denmark, Sweden) of births. Higher postterm rates were associated with a greater proportion of babies with birthweight 4500 g or more. Fetal and early neonatal mortality rates were higher among postterm births than among births at 40 weeks. Countries with higher proportions of births with a nonspontaneous onset of labour had lower postterm birth rates. The shapes of the gestational-age distributions at term varied. In some countries, there was a sharp cutoff in deliveries at 40 weeks, while elsewhere this occurred at 41 weeks. CONCLUSIONS: These results suggest that practices for managing pregnancies continuing beyond term differ in Europe and raise questions about the health and other impacts in countries with markedly high or low postterm rates. Some variability in these rates may also be due to methods for determining gestational age, which has broader implications for international comparisons of gestational age, including rates of postterm and preterm births and small-for-gestational-age newborns.

[Distinction between bacterial and aseptic meningitis in children: refinement of a clinical decision rule]. / Distinction entre les méningites bactériennes et virales chez l'enfant: affinement d'une règle de décision clinique.

OBJECTIVES: To refine and to re-validate the best current tool (the Nigrovic rule: ''outpatient management may be considered for children without seizure, blood neutrophil count>or=10,000/mm(3), positive cerebrospinal fluid -CSF- Gram-staining, CSF protein>or=80 mg/dl, or CSF neutrophil count>or=1,000/mm(3)'') proposed to distinguish between aseptic meningitis (AM) and bacterial meningitis (BM) in the emergency department. METHODS: Children hospitalized for BM between 1995 and 2004, or AM between 2000 and 2004 were included, and randomly divided into derivation (111 children, 14 BM) and internal validation (57 children, 7 BM) sets. The Nigrovic rule was refined on the derivation set, introducing new variables (purpura, toxic appearance and high serum procalcitonin), changing variables thresholds (CSF protein) and withdrawing some variables (blood neutrophil count, CSF neutrophil count), according to previous results, with the aim to obtain 100% sensitivity user friendly tool. The refined rule was then applied on the internal validation set, stayed blinded during the derivation process. RESULTS: The refined rule was: start antibiotics in case of seizure, purpura, toxic appearance, procalcitonin>or=0.5 ng/ml, positive CSF Gram-staining, or CSF protein>or=50 mg/dl. The refined rule had 100% sensitivity on the derivation and the internal validation sets (95% confidence interval 78-100, and 65-100, respectively) with 62 and 51% specificity, respectively. CONCLUSION: The refined rule (called Meningitest) was a highly sensitive, specific and user friendly tool that could allow to safely avoid>50% a posteriori unuseful antibiotic treatments for patients with AM.

Level of perinatal care of the maternity unit and rate of cesarean in low-risk nulliparas.

OBJECTIVE: To analyze the influence of level of perinatal care of the maternity unit on the rate of cesarean delivery during labor among women with low-risk pregnancies. METHODS: Using data from the PREMODA (PREsentation et MODe d'Accouchement: presentation and mode of delivery) study of 138 French maternity units, the delivery method in 3,654 low-risk nulliparas (live singleton fetus in cephalic presentation at term [37-41 weeks of gestation], born weighing 2,500-4,500 g, no uterine scar, no cesarean before labor, and no induction of labor for maternal or fetal disorders) was analyzed. Independent variables included maternal and fetal characteristics and the level of perinatal care of the maternity unit (level 1, 2a, 2b, and 3; where levels 2b and 3 routinely manage high-risk pregnancies). Univariable and multivariable analysis with a multilevel logistic model explored the factors associated with cesarean delivery during labor. RESULTS: Overall, the rate of cesarean during labor was 11.7%. The rate was significantly higher in level 2b (odds ratio 1.5, 95% confidence interval 1.1-2.1) and 3 (odds ratio 1.3, 95% confidence interval 1.0-1.9) maternity units than in level 1 facilities. The size and status of the facilities did not significantly affect these rates. Risk factors for cesarean were older maternal age, non-French origin, gestational age of 41 weeks, male sex, and high birth weight. CONCLUSION: Maternity units that frequently manage high-risk pregnancies (levels 2b and 3) have higher rates of cesareans during labor for their population of nulliparas at low risk than do facilities that deal mainly with low-risk pregnancies (level 1). LEVEL OF EVIDENCE: II-2.

[Trends in perinatal health in metropolitan France between 1995 and 2003: results from the National Perinatal Surveys]. / La santé périnatale en France métropolitaine de 1995 à 2003. Résultats des enquêtes nationales périnatales.

OBJECTIVE: To study trends in the main indicators of health, medical practice and risk factors in France. Population and method. A sample of all births during one week was set up in 1995 (N=13,318), 1998 (N=13,718) et 2003 (N=14,737). We compared data from these three years. RESULTS: Between 1995 and 2003, there was an increase in maternal age, a development of some characteristics of care (HIV screening procedure, maternal serum screening of Down syndrome, in utero transfers) and an increase in the proportion of caesarean sections, epidurals and spinal anesthesia. The proportion of livebirths before 37 weeks of gestation and the proportion of newborns under 2,500 g slightly increased but the differences were mainly between 1995 et 1998. In 2003, obstetrician gynecologists were the main care providers during pregnancy. However 24.3% of women had their first visit with a general practitioner. For the following visits, 15.4% of women had seen a GP at least once and 26.9% had seen a midwife in maternity unit at least once. CONCLUSION: Because of the trends in obstetrical practice and organisation of services, routine national perinatal surveys are useful to show major changes and yield quick answers to specific questions.

Quantitative ultrasound parameters as well as bone mineral density are better predictors of trochanteric than cervical hip fractures in elderly women. Results from the EPIDOS study.

RATIONALE: Hip fractures can be separated into cervical and trochanteric fractures. Trochanteric fractures have been associated with up to twice the short-term mortality of cervical fractures in the elderly. There is also evidence suggesting that the mechanisms are different. Evidence from the literature remains limited on the predictive power of bone mineral density (BMD) and quantitative ultrasounds (QUS) for both types of hip fractures. METHODS: 5703 elderly women aged 75 years or more, who were recruited from the voting lists in the EPIDOS study, and had baseline calcaneal ultrasounds (QUS) and DXA measurements at the hip and the whole body, were analyzed in this paper. Among those, 192 hip fractures occurred during an average follow-up of 4 years, 108 cervical and 84 trochanteric fractures. RESULTS: Femoral neck, trochanteric and whole body BMD were able to predict trochanteric hip fracture (RR's and 95% CI were, respectively, 3.2 (2.4-4.2); 4.8 (3.5-6.6); and 2.8 (2.2-3.6)) more accurately than cervical fractures (respectively, 2.1 (1.7-2.7); 2.3 (1.8-3.0); 1.2 (1.0-1.6)). All ultrasound parameters, SOS, BUA, and stiffness index (SI) were significant predictors of trochanteric (RR's respectively 3.0 (2.2-4.1), 2.5(2.0-3.1), and 3.5(2.6-4.7)) but not cervical fractures. After adjustment for femoral neck or trochanteric BMD ultrasound parameters were still significant predictors of trochanteric fracture, and stiffness tended to be a better predictor of trochanteric fractures than either BUA or SOS with a relative risk of 2.25 (1.6-3.1). CONCLUSIONS: A significant decrease of all bone measurements, BMD and QUS, was highly predictive of trochanteric fractures, whereas a decrease of femoral neck and trochanteric BMD were only associated with a slight increase in cervical fracture risk and a low total body BMD or QUS parameters were not significant predictors of cervical fractures. In women who sustained a hip fracture, the decrease of BMD and QUS values increases the risk of trochanteric fracture as compared to cervical fracture. Trochanteric fractures were mostly a consequence of a generalized low BMD and QUS, whereas other parameters might be involved in cervical fractures.

Does smoking in pregnancy modify the impact of antenatal steroids on neonatal respiratory distress syndrome? Results of the Epipage study.

OBJECTIVES: To assess the relation between cigarette smoking during pregnancy and neonatal respiratory distress syndrome (RDS) in very preterm birth, and to analyse the differential effect of antenatal steroids on RDS among smokers and non-smokers. DESIGN: A population based cohort study (the French Epipage study). SETTING: Regionally defined births in France. METHODS: A total of 858 very preterm liveborn singletons (27-32 completed weeks of gestation) of the French Epipage study were included in this analysis. The odds ratio for RDS in relation to smoking in pregnancy was estimated using a logistic regression to control for gestational age. The odds ratio for RDS in relation to antenatal steroids was estimated taking into account an interaction between antenatal steroids and cigarette smoking, using multiple logistic regression to control for gestational age, birthweight ratio, main causes of preterm birth, mode of delivery, and sex. RESULTS: The odds ratio for RDS in relation to smoking in pregnancy adjusted for gestational age (aOR) was 0.59 (95% confidence interval (CI) 0.44 to 0.79). The aOR for RDS in relation to antenatal steroids was 0.31 (95% CI 0.19 to 0.49) in babies born to non-smokers and 0.63 (95% CI 0.38 to 1.05) in those born to smokers; the difference was significant (p = 0.04). CONCLUSIONS: Cigarette smoking during pregnancy is associated with a decrease in the risk of RDS in very preterm babies. Although antenatal steroids reduce the risk of RDS in babies born to both smokers and non-smokers, the reduction is smaller in those born to smokers.

[Neonatal mortality in France: usefulness of a neonatal death certificate]. / La mortalité néonatale en France: bilan et apport du certificat de décès néonatal.

UNLABELLED: A neonatal death certificate was introduced in France in 1997. It provides detailed data on the causes of death and the characteristics of newborn, birth and parents. Our aim was to describe the new results of this certificate. METHOD: All deaths in 1999 in the first 27 days of life were included (N=2036). Certificates were analysed using the usual process, especially following the International Classification of Diseases. RESULTS: The neonatal death certificate was used for 87% of deaths. The proportion of documented items was 96% for gestational age and birthweight, 87% for maternal age and parity and 70% for maternal occupation. Almost three quarters of the deaths occurred in the first 6 days (36.9% in the first 24 hours and 35.1% between one and six days). 30.5% of the died infants were born before 27 weeks of gestation and 36.5% between 27 and 36 weeks. A shift in medical care was observed at 26 weeks, with an increase in caesarean sections before labour and newborn referrals. In all, 63.3% of neonatal deaths were due to perinatal conditions, and 27.9% to congenital anomalies. The proportion of deaths explained by congenital anomalies was higher for longer gestational age: 14% of deaths between 25 and 28 weeks of gestation vs 38 to 43% between 33 and 42 weeks. CONCLUSION: The neonatal death certificate was well accepted; however the data on detailed causes of death and parent's characteristics were insufficient. Analysis of the circumstances and the causes of death is facilitated with the neonatal death certificate and it will be developped in the future.

[Treatment strategies for neonatal pulmonary morbidity in Europe]. / Prise en charge de l'immaturité pulmonaire en néonatologie: enquête sur les pratiques européennes.

OBJECTIVES: To survey practices in 14 European countries and to describe strategies for the prevention and treatment of pulmonary morbidity in very preterm newborns. METHODS: Questionnaires covering the use of prenatal steroids, surfactant and postnatal steroids were sent in 1999-2000 to every neonatal unit taking very preterm newborns in charge in population-based areas covering at least 20,000 births annually. One questionnaire was sent by surveyed unit. RESULTS: Results are given concerning these three treatments and compared to evidence based recommendations. CONCLUSION: Antenatal steroids were given at recommended terms. Surfactant was prescribed with respect of best practices. Postnatal steroids utilisation was not well described.

[Post-partum: Guidelines for clinical practice--Short text]. / Post-partum: recommandations pour la pratique Clinique--Texte court.

OBJECTIVE: To determine the post-partum management of women and their newborn whatever the mode of delivery. MATERIAL AND METHODS: The PubMed database, the Cochrane Library and the recommendations from the French and foreign obstetrical societies or colleges have been consulted. RESULTS: Because breastfeeding is associated with a decrease in neonatal morbidity (lower frequency of cardiovascular diseases, infectious, atopic or infantile obesity) (EL2) and an improvement in the cognitive development of children (EL2), exclusive and extended breastfeeding is recommended (grade B) between 4 to 6 months (Professional consensus). In order to increase the rate of breastfeeding initiation and its duration, it is recommended that health professionals work closely with mothers in their project (grade A) and to promote breastfeeding on demand (grade B). There is no scientific evidence to recommend non-pharmacological measures of inhibition of lactation (Professional consensus). Pharmacological treatments for inhibition of lactation should not be given routinely to women who do not wish to breastfeed (Professional consensus). Because of potentially serious adverse effects, bromocriptin is contraindicated in inhibiting lactation (Professional consensus). For women aware of the risks of pharmacological treatment of inhibition of lactation, lisuride and cabergolin are the preferred drugs (Professional consensus). Whatever the mode of delivery, numeration blood count is not systematically recommended in a general population (Professional consensus). Anemia must be sought only in women with bleeding or symptoms of anemia (Professional consensus). The only treatment of post-dural puncture headache is the blood patch (EL2), it must not be carried out before 48 h (Professional consensus). Women vaccination status and their family is to be assessed in the early post-partum (Professional consensus). Immediate postoperative monitoring after caesarean delivery should be performed in the recovery room, but in exceptional circumstances, it may be performed in the delivery unit provided safety rules are maintained and regulatory authorities are informed (Professional consensus). An analgesic multimodal protocol developed by the medical team should be available and oral way should be favored (Professional consensus) (grade B). For every cesarean delivery, thromboprophylaxis with elastic stockings applied on the morning of the surgery and kept for at least 7 postoperative days is recommended (Professional consensus) with or without the addition of LMWH according to the presence or not of additional risk factors, and depending on the risk factor (major, minor). Early postoperative rehabilitation is encouraged (Professional consensus). Postpartum visit should be planned 6 to 8 weeks after delivery and can be performed by an obstetrician, a gynecologist, a general practitioner or a midwife, after normal pregnancy and delivery (Professional consensus). Starting effective contraception later 21 days after delivery in women who do not want closely spaced pregnancy is recommended (grade B), and to prescribe it at the maternity (Professional consensus). According to the postpartum risk of venous thromboembolism, the combined hormonal contraceptive use before six postpartum weeks is not recommended (grade B). Rehabilitation in asymptomatic women in order to prevent urinary or anal incontinence in medium or long-term is not recommended (Expert consensus). Pelvic-floor rehabilitation using pelvic-floor muscle contraction exercises is recommended to treat persistent urinary incontinence at 3 months postpartum (grade A), regardless of the type of incontinence. Postpartum pelvic-floor rehabilitation is recommended to treat anal incontinence (grade C). Postpartum pelvic-floor rehabilitation is not recommended to treat or prevent prolapse (grade C) or dyspareunia (grade C). The optimal time for maternity discharge for low risk newborn depends more on the organisation of the post-discharge follow up (Professional consensus). The months following the birth are a transitional period, and psychological alterations concern all parents (EL2). It is more difficult in case of psychosocial risk factors (EL2). In situations of proven psychological difficulties, the impact on the psycho-emotional development of children can be important (EL3). Among these difficulties, postpartum depression is the most common situation. However, the risk is generally higher in the perinatal period for all mental disorders (EL3). CONCLUSION: Postpartum is, for clinicians, a unique and privileged opportunity to address the physical, psychological, social and somatic health of their patients.
