Minimum evidence-based care in intrauterine growth-restricted fetuses and neonatal prognosis.

Atallah A, Butin M, Moret S, Claris O, Massoud M, Gaucherand P, Doret-Dion M.


Introduction: There is clear evidence that fetuses with intrauterine growth restriction (IUGR) do not receive the minimum evidence-based care during their antenatal management.

Objective: Considering that optimal management of IUGR may reduce neonatal morbi-mortality in IUGR, the objective of the present study was to evaluate the impact of antenatal management of IUGR according to the recommendations of the French college of gynecologists and obstetricians (CNGOF) on the neonatal prognosis of IUGR fetuses.

Study design: From a historical cohort of 31,052 children, born at the Femme Mère Enfant hospital (Lyon, France) between January 1, 2011 and December 31, 2017, we selected the population of IUGR fetuses. The minimum evidence-based care (MEC) in the antenatal management of fetuses with IUGR was defined according to the CNGOF recommendations and neonatal prognosis of early and late IUGR fetuses were assessed based on the whether or not they received MEC. The neonatal prognosis was defined according to a composite criterion that included neonatal morbidity and mortality.

Results: A total of 1020 fetuses with IUGR were studied. The application of MEC showed an improvement in the neonatal prognosis of early-onset IUGR (p = 0.003), and an improvement in the neonatal prognosis of IUGR born before 32 weeks (p = 0.030). Multivariate analysis confirmed the results showing an increase in neonatal morbi-mortality in early-onset IUGR in the absence of MEC with OR 1.79 (95% CI 1.01–3.19).

Conclusion: Diagnosed IUGR with MEC had a better neonatal prognosis when born before 32 weeks. Regardless of the birth term, MEC improved the neonatal prognosis of fetuses with early IUGR. Improvement in the rate of MEC during antenatal management has a significant impact on neonatal prognosis.

 - Christine Rousset-Jablonski : « Santé de la femme et pathologies chroniques : exemple de la mucoviscidose »

Chez les femmes atteintes de  maladies chroniques, le suivi et la prise en charge gynécologique (participation aux dépistages mammaire et cervical, information et couverture contraceptive...) sont parfois insuffisants en regard des recommandations, et en comparaison avec les femmes de la population générale. Cependant, certaines particularités liées à leur pathologie justifierait une prise en charge spécifique et adaptée. 

L’espérance de vie des patients atteints de mucoviscidose s’est améliorée. En conséquence, des problématiques et questions nouvelles émergent, comme celles de la prise en charge gynécologique et de la santé sexuelle des femmes adultes atteintes de mucoviscidose.

L’objectif de ce travail a été d’évaluer la prise en charge gynécologique des femmes atteintes de mucoviscidose, de décrire leurs comorbidités gynécologiques, et de proposer des pistes d’amélioration de prise en charge et de prévention.

Medullary thyroid cancer outcomes in patients with undetectable versus normalized postoperative calcitonin levels.

Fanget F, Demarchi MS, Maillard L, Lintis A, Decaussin M, Lifante JC.


Background: Calcitonin (Ct) is a sensitive diagnostic biomarker and one of the most important prognostic factors in medullary thyroid cancer (MTC). This study aimed to evaluate progression-free survival and recurrence rates of MTC associated with undetectable compared with normalized serum Ct levels after surgery.

Methods: This retrospective observational study included patients operated for MTC at the Digestive and Endocrine Surgery Department of Lyon Sud Hospital Centre between 2000 and 2019. Clinical and pathological factors were correlated with postoperative Ct concentrations. Undetectable and normalized Ct concentrations were defined as below 2 pg/ml and 2-10 pg/ml respectively.

Results: Overall, 176 patients were treated for MTC, and 127 were considered biochemically cured after surgery. Of these, 24 and 103 had normalized and undetectable Ct concentrations respectively. Patients with Ct level normalization had a 25 per cent risk of disease recurrence, compared with 3 per cent in patients with undetectable Ct levels after surgery. The presence of metastasis in two or more compartments was predictive of failure to achieve undetectable Ct concentrations after surgery and an increased risk of recurrence.

Conclusion: Among patients with biochemically cured MTC, those with undetectable or normalized Ct concentrations after surgery had different risks of recurrence. Simply assessing postoperative Ct normalization can be falsely reassuring, and long-term follow-up is needed.

Comparison of rural and urban French GPs' activity: a cross-sectional study.

Bénédicte Lurquin, Nadir Kellou, Cyrille Colin, Laurent Letrilliart.


Introduction: In various countries, a shortage of general practitioners (GPs) and worrying health statistics on risk factors, morbidity and mortality have been observed in rural areas. However, few comparative data are available on GP activities according to their location. The aim of this study was to analyse French GP activities according to their rural or urban practice location.

Methods: This study was ancillary to the Eléments de la COnsultation en médecine GENérale (ECOGEN) study, which was a cross-sectional, multicentre, national study conducted in 128 French general practices in 2012. Data were collected by 54 interns in training during a period of 20 working days from December 2011 to April 2012. GP practice location was classified as rural area, urban cluster or urban area. The International Classification of Primary Care (ICPC-2) was used to classify reasons for encounter, health problem assessments, and processes of care. Univariate analyses were performed for all dependent variables, then multivariable analyses for key variables, using hierarchical mixed-effect models.

Results: The database included 20 613 consultations. The mean yearly number of consultations per GP was higher in rural areas (p<0.0001), with a shorter consultation length (p<0.0001). No difference was found for GP sex (p=0.41), age (p=0.87), type of fees agreement (p=0.43), and type of practice (p=0.19) according to their practice location. Urban patients were younger, and there was a lower percentage of patients over 75 years (p<0.001). GPs more frequently consulted at patients' homes in rural areas (p<0.0001). The mean number of chronic conditions managed was higher in rural areas and urban clusters than in urban areas (p<0001). Hypertension (p<0.0001), type 2 diabetes (p=0.003), and acute bronchitis/bronchiolitis (p=0.01) were more frequently managed in rural areas than in urban clusters and areas. Health maintenance/prevention (p<0.0001) and no disease situations (p<0.0001) were less frequent in rural areas. Drug prescription was more frequent in rural areas than in urban clusters and areas (p<0.0001). Multivariable analysis confirmed the influence of a GP's rural practice location on the consultation length (p<0.0001), the number of chronic conditions per consultation (p<0.0001) and the number of health maintenance/prevention situations (p<0.0001), and a trend towards a higher yearly number of consultations per GP (p=0.09).

Conclusion: French rural GPs tend to have a higher workload than urban GPs. Rural patients have more chronic conditions to be managed but are offered fewer preventive services during consultations. It is necessary to increase the GP workforce and develop cooperation with allied health professionals in rural areas.
