Arterial and venous complications after fertility treatment: A French nationwide cohort study.

OBJECTIVES: To determine whether the risk of thromboembolic complications is higher in women following unsuccessful fertility treatment (FT) and in pregnant women following successful FT, and whether the risk differs according to FT type. STUDY DESIGN: This is an observational prospective cohort study. All French women aged 18-45 years who received FT between 2013 and 2015 were selected from the French health insurance claim database which registers healthcare consumption for the entire French population. All FT reimbursed over a 28-day period from the date of the first FT were considered to constitute one FT cycle. Each FT cycle was classified according to type: either simple ovulation induction (OI) or ovulation stimulation (OS). All hospitalisations with a diagnosis of venous thromboembolism (VTE), arterial thrombosis (AT) or ovarian hyperstimulation syndrome (OHSS) were identified for the selected women in the French hospital discharge database. Poisson regressions were used to estimate incidence rate ratios (IRR) by comparing i) the incidence of thromboembolic complications (i.e., VTE and AT) and OHSS following unsuccessful FT cycles with the incidence of these two diseases in all non-pregnant women of the same age range (i.e. non-pregnant control group), and ii) incidence of thromboembolic complications and OHSS in women who became pregnant following successful FT with the incidence in women of the same age range with spontaneous (i.e., no FT) pregnancies (i.e., pregnant control group (spontaneous pregnancy)). RESULTS: During the study period, 277,913 women underwent FT, for a total of 788,007 FT cycles, with 82,821 FT-related pregnancies. Among unsuccessful FT cycles, 75 VTE and 43 AT were observed. OS treatment cycles but not OI were associated with a higher risk of VTE than in reference group (age-adjusted IRR 1.74, 95%CI [1.30-2.34]). Among FT-related pregnancies, 207 VTE and 35 AT were reported. VTE and AT incidence rates during the first trimester were higher after OS treatment cycles than in the pregnant control group (spontaneous pregnancy) after adjusting for age and twin/multiple pregnancies (IRRVTE = 3.29, 95%CI [2.24-4.81]; IRRAT = 2.63, 95%CI [1.06-6.51]). CONCLUSION: Monitoring women undergoing FT, especially OS, irrespective of pregnancy status is crucial. The risk of thromboembolic complications in the first trimester for FT-related pregnancies seems to be higher than that for spontaneous pregnancies.

[Health status of populations living in French overseas territories in 2012, compared with metropolitan France: An analysis of the national health insurance database]. / L'état de santé des populations des départements d'outre-mer en 2012, comparativement à la métropole : une analyse de la base nationale de l'Assurance maladie.

BACKGROUND: This study uses healthcare consumption to compare the health status of beneficiaries of the French national health insurance general scheme between individuals living in French overseas territories (FOT) and those living in metropolitan France. METHODS: Data were extracted from the French national health insurance database (Sniiram) for 2012, using algorithms, 56 groups of diseases and 27 groups of hospital activity were isolated. Standardized morbidity ratio for age and sex (SMR) were used to compare FOT to mainland France. RESULTS: Compared with mainland France, people living in the four FOT had high SMR for diabetes care (Guadeloupe 1.9; Martinique 1.7; Guyane 1.9; La Réunion 2.3), dialysis (2.7; 2.4; 3.8; 4.4), stroke (1.2; 1.1; 2.0; 1.5), and hospitalization for infectious diseases (1.9; 2.5; 2.4; 1.4) and obstetrics (1.4; 1.2; 1.9; 1.2). Care for inflammatory bowel disease or cancer were less frequent except for prostate in Martinique and Guadeloupe (2.3). People living in Martinique, Guadeloupe and la Reunion had more frequently care for psychotic disorders (2.0; 1.7; 1.2), dementia (1.1; 1.3; 11), epileptic seizures (1.4; 1.4; 16) and hospitalizations for burns (2.6; 1.7; 2.9). In la Reunion, people had more frequently coronary syndrome (1.3), cardiac heart failure (1.6), chronic respiratory diseases except cystic fibrosis (1.5), drug addiction (1.4) and hospitalizations for cardiovascular catheterization (1.4) and toxicology, poisoning, alcohol (1.7). Other differences were observed by gender: HIV infection, peripheral arterial disease, some chronic inflammatory disease (lupus) were more frequent in women living in Martinique or Guadeloupe, compared to women from mainland France and psychotic disorders for men. From la Reunion, men had more frequently liver and pancreatic diseases and hospitalisation for toxicology, poisoning, alcohol than men from mainland France. CONCLUSION: This study highlights the utility of administrative database to compare and follow population health status considering healthcare use. Specific Public Health policies are justified for FOT, taking into account the specific context of each FOT, the necessity of prevention initiatives and screening to reduce the frequency of the chronic diseases.

Ketoacidosis at diagnosis of type 1 diabetes in French children and adolescents.

OBJECTIVES: This study aimed to evaluate the frequency of diabetic ketoacidosis (DKA) and its associated factors at the diagnosis of type 1 diabetes (T1D) in French children and adolescents prior to launching a public-health campaign of information to prevent DKA. PATIENTS AND METHODS: Over a 1-year period, 1299 youngsters (aged < 15 years) were diagnosed with T1D at 146 paediatric centres in all regions of France. Age, gender, duration of symptoms, patient's pathway to diagnosis, clinical and biological signs, and family history of T1D were collected for each newly diagnosed patient. DKA was defined as pH < 7.30 or bicarbonate < 15 mmol/L, and severe DKA as pH < 7.10 or bicarbonate < 5 mmol/L. RESULTS: At the time of diagnosis, 26% of the children were aged 0-5 years, 34% were 5-10 years and 40% were 10-15 years. The overall prevalence of DKA was 43.9% (0-5 years: 54.2%; 5-10 years: 43.4%; and 10-15 years: 37.1%) and 14.8% for severe DKA (0-5 years: 16.6%; 5-10 years: 14.4%; and 10-15 years: 13.9%; < 2 years: 25.3%). Severe DKA was more frequent when the child was hospitalized at the family's behest (26.6%) than when referred by a general practitioner (7.6%) or paediatrician (5.1%; 30.6%, 53.7% and 9.2%, respectively, by patients' age group). The frequency of DKA decreased to 20.1% (severe DKA: 4.4%) in families with a history of T1D. Multivariate analysis showed that age, pathway to diagnosis, duration of polyuria/polydipsia (< 1 week) and family history of T1D were associated with the presence of DKA, while pathway to diagnosis and family history of T1D were associated with severe DKA. CONCLUSION: DKA at the time of T1D diagnosis in children and adolescents is frequent and often severe. Patients' age, pathway to hospitalization and family history of diabetes were the main factors associated with DKA. These data suggest that a public-health campaign to prevent DKA at diagnosis can help reduce the frequency of DKA and also provide baseline data for evaluating the efficacy of such a campaign.
