Conservative management or cesarean hysterectomy for placenta accreta spectrum: the PACCRETA prospective study.

BACKGROUND: Placenta accreta spectrum is a life-threatening condition that has increased dramatically in recent decades along with cesarean rates worldwide. Cesarean hysterectomy is widely practiced in women with placenta accreta spectrum; however, the maternal outcomes after cesarean hysterectomy have not been thoroughly compared with the maternal outcomes after alternative approaches, such as conservative management. OBJECTIVE: This study aimed to compare the severe maternal outcomes between women with placenta accreta spectrum treated with cesarean hysterectomy and those treated with conservative management (leaving the placenta in situ). STUDY DESIGN: From a source population of 520,114 deliveries in 176 hospitals (PACCRETA study), we designed an observational cohort of women with placenta accreta spectrum who had either a cesarean hysterectomy or a conservative management (the placenta left in situ) during cesarean delivery. Clinicians prospectively identified women meeting the inclusion criteria and included them at delivery. Data collection started only after the women had received information and agreed to participate in the study in the immediate postpartum period. The primary outcome was the transfusion of >4 units of packed red blood cells within 6 months after delivery. Secondary outcomes were other maternal complications within 6 months. We used propensity score weighting to account for potential indication bias. RESULTS: Here, 86 women had conservative management and 62 women had cesarean hysterectomy for placenta accreta spectrum during cesarean delivery. The primary outcome occurred in 14 of 86 women in the conservative management group (16.3%) and 36 of 61 (59.0%) in the cesarean hysterectomy group (risk ratio in propensity score weighted model, 0.29; 95% confidence interval, 0.19-0.45). The rates of hysterectomy, total estimated blood loss exceeding 3000 mL, any blood product transfusion, adjacent organ injury, and nonpostpartum hemorrhage-related severe maternal morbidity were lower with conservative management than with cesarean hysterectomy (all adjusted, P≤.02); but, the rates of arterial embolization, endometritis, and readmission within 6 months of discharge were higher with conservative management than with cesarean hysterectomy. CONCLUSION: Among women with placenta accreta spectrum who underwent cesarean delivery, conservative management was associated with a lower risk of transfusion of >4 units of packed red blood cells within 6 months than cesarean hysterectomy.

R-CHOP 14 with or without radiotherapy in nonbulky limited-stage diffuse large B-cell lymphoma.

The benefit of radiotherapy (RT) after chemotherapy in limited-stage diffuse large B-cell lymphoma (DLBCL) remains controversial. We conducted a randomized trial in patients with nonbulky limited-stage DLBCL to evaluate the benefit of RT after rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP). Patients were stratified according to the modified International Prognostic Index, including lactate dehydrogenase, Eastern Cooperative Oncology Group performance status, age, and disease stage. The patients received 4 or 6 consecutive cycles of R-CHOP delivered once every 2 weeks, followed or not by RT at 40 Gy delivered 4 weeks after the last R-CHOP cycle. All patients were evaluated by fluorodeoxyglucose-positron emission tomography scans performed at baseline, after 4 cycles of R-CHOP, and at the end of treatment. The primary objective of the trial was event-free survival (EFS) from randomization. The trial randomly assigned 165 patients in the R-CHOP arm and 169 in the R-CHOP plus RT arm. In an intent-to-treat analysis with a median follow-up of 64 months, 5-year EFS was not statistically significantly different between the 2 arms, with 89% ± 2.9% in the R-CHOP arm vs 92% ± 2.4% in the R-CHOP plus RT arm (hazard ratio, 0.61; 95% confidence interval [CI], 0.3-1.2; P = .18). Overall survival was also not different at 92% (95% CI, 89.5%-94.5%) for patients assigned to R-CHOP alone and 96% (95% CI, 94.3%-97.7%) for those assigned to R-CHOP plus RT (P = not significant). R-CHOP alone is not inferior to R-CHOP followed by RT in patients with nonbulky limited-stage DLBCL. This trial was registered at www.clinicaltrials.gov as #NCT00841945.

Risk factors for placenta accreta spectrum disorders in women with any prior cesarean and a placenta previa or low lying: a prospective population-based study.

This study aimed to identify the risk factors for placenta accreta spectrum (PAS) in women who had at least one previous cesarean delivery and a placenta previa or low-lying. The PACCRETA prospective population-based study took place in 12 regional perinatal networks from 2013 through 2015. All women with one or more prior cesareans and a placenta previa or low lying were included. Placenta accreta spectrum (PAS) was diagnosed at delivery according to standardized clinical and histological criteria. Of the 520,114 deliveries, 396 fulfilled inclusion criteria; 108 were classified with PAS at delivery. Combining the number of prior cesareans and the placental location yielded a rate ranging from 5% for one prior cesarean combined with a posterior low-lying placenta to 63% for three or more prior cesareans combined with placenta previa. The factors independently associated with PAS disorders were BMI ≥ 30, previous uterine surgery, previous postpartum hemorrhage, a higher number of prior cesareans, and a placenta previa. Finally, in this high-risk population, the rate of PAS disorders varies greatly, not only with the number of prior cesareans but also with the exact placental location and some of the women's individual characteristics. Risk stratification is thus possible in this population.

The Global School Adaptation score: a new neurodevelopmental assessment tool for very preterm children at five years of age.

OBJECTIVE: To determine the usefulness of a neurodevelopmental assessment tool consisting of a questionnaire administered to teachers to measure the Global School Adaptation (GSA) scores of very preterm children at the age of 5 years. STUDY DESIGN: A sample of 445 very preterm children (<35 weeks of gestation) was assessed at 5 years of age using GSA and IQ scores. According to the consistency between the scores, children were determined to be well classified, intermediately classified, or misclassified. The differences between groups were assessed through univariate and multivariate logistic regression. RESULTS: The GSA score was highly or intermediately consistent with the IQ score for 89.2% of the children, and 10.8% were considered misclassified. Children with a higher GSA than IQ score had more autonomy and self-confidence (P < .01), and those with a lower GSA than IQ score had more behavioral problems (P < .01). Analysis by logistic regression showed that sex and gestational age significantly affected the consistency between the 2 scores. Thus, girls were less likely to have a lower GSA than IQ score (aOR = 0.45; 95% CI: 0.24-0.84; P = .01), and a lower gestational age significantly increased the likelihood of having a higher GSA than IQ score (for children born between 24 and 28 weeks of gestation: aOR = 2.70; 95% CI: 1.23-5.92; P = .01). CONCLUSIONS: The GSA score is a simple, inexpensive, and reliable screening tool for assessing neurodevelopment in very preterm children at 5 years of age.

Breastfeeding and respiratory, ear and gastro-intestinal infections, in children, under the age of one year, admitted through the paediatric emergency departments of five hospitals.

Background: Breastfeeding is a protective factor against respiratory and intestinal infections in developing countries. In developed countries, proof of this protection is more difficult to show. The objective of the study is to compare the proportion of children breastfed during their first year in groups of children with infectious pathologies supposedly prevented by breastfeeding and children free of these infectious pathologies. Method: Questionnaires about diet, socio-demographic data and the motive for consultation were given to the parents upon arrival in the paediatric emergency departments of 5 hospitals located in Pays de Loire (France) in 2018 and 2019. Children with lower respiratory tract infections, acute gastroenteritis and acute otitis media were included in the case group (A), children admitted for other reasons were included in the same control group (B). Breastfeeding was classified as exclusive or partial. Results: During the study period, 741 infants were included, of which 266 (35.9%) in group A. In this group, children were significantly less likely to have been breastfed at the time of admission than children in group B: for example, for children under 6 months, 23.3% were currently breastfed in group A, vs. 36.6% (weaned BF or formula diet) in group B [OR = 0.53 (0.34-0.82); p = 0.004]. Similar results were found at 9 and 12 months. After taking into account the age of the patients, the same results were confirmed with an aOR = 0.60 (0.38-0.94) (p = 0.02) at 6 months, but with when considering six variables six variables, aOR was not significative aOR = 0.65 (0.40-1.05); p = 0.08), meaning that factors such as the childcare out of home, socio-professional categories, and the pacifier decrease the protective effect of breastfeeding. Sensitivity analyses (age-matching, analysis by type of infection) showed the same protection effect provided by breastfeeding when it was pursued for at least 6 months and also that the protective effect of breastfeeding is especially true against gastro-enteritis. Conclusion: Breastfeeding is a protective factor against respiratory, gastrointestinal and ear infections when pursued at least 6 months after birth. Other factors such as collective childcare, pacifiers and low parental professional status can reduce the protective effect of breastfeeding.

Formative evaluation to improve prevention of sudden infant death syndrome (SIDS): a prospective study.

AIM: To evaluate formative evaluation, a pedagogic method that sensitizes mothers to sudden infant death syndrome (SIDS), as a new way to improve prevention of SIDS. METHODS: Prospective and randomized study. Mothers in a test group (n = 148) received an educative questionnaire about SIDS during maternity stay. Three months later, we evaluated, by a telephonic interview, their scores of knowledge and observance of the recommendations in comparison with a control group (n = 144). RESULTS: Mothers' scores at the educative questionnaire was 5.12 (1.52) [mean(standard deviation)]. The scores performed 3 months later were better in test group for knowledge [7.64 (1.56) vs. 7.16 (1.61), p < 0.01] and for observance [8.28 (1.51) vs. 7.62 (1.72), p < 0.001]. Logistic regression analysis confirmed the benefits in test group regarding knowledge of SIDS risk factors [ORa = 1.69 (1.02-2.77), p < 0.05], of the advice to avoid overheating infants [ORa = 2.50 (1.43-4.38), p < 0.01] and of the risks of bed sharing [ORa = 2.7 (1.6-4.5), p < 0.001]. There was a significant association between non-compliance with the sleeping position recommendation and unemployment (p < 0.01) and absence of postsecondary school education (p < 0.01). CONCLUSION: Formative evaluation using an educative questionnaire could improve maternal awareness on SIDS risk factors and their compliance with recommendations about SIDS prevention.

Procalcitonin as a marker of bacterial infection in children undergoing cardiac surgery with cardiopulmonary bypass.

BACKGROUND: Owing to systemic inflammatory response syndrome, the diagnosis of post-operative infection after cardiopulmonary bypass is difficult to assess in children with the usual clinical and biological tools. Procalcitonin could be informative in this context. METHODS: Retrospective study in a paediatric intensive care unit. Blood samples were collected as soon as infection was clinically suspected and a second assay was performed 24 hours later. Using referenced criteria, children were retrospectively classified into two groups: infected and non-infected. RESULTS: Out of the 95 children included, 14 were infected. Before the third post-operative day, procalcitonin median concentration was significantly higher in the infected group than in the non-infected group - 20.24 nanograms per millilitre with a 25th and 75th interquartile of 15.52-35.71 versus 0.72 nanograms per millilitre with a 25th and 75th interquartile of 0.28 to 5.44 (p = 0.008). The area under the receiver operating characteristic curve was 0.89 with 95% confidence intervals from 0.80 to 0.97. The best cut-off value to differentiate infected children from healthy children was 13 nanograms per millilitre with 100% sensitivity - 95% confidence intervals from 51 to 100 - and 85% specificity - 95% confidence intervals from 72 to 91. After the third post-operative day, procalcitonin was not significantly higher in infected children - 2 nanograms per millilitre with a 25th and 75th interquartile of 0.18 to 12.42 versus 0.37 nanograms per millilitre with a 25th and 75th interquartile of 0.24 to 1.32 (p = 0.26). The area under the receiver operating characteristic curve was 0.62 with 95% confidence intervals from 0.47 to 0.77. A procalcitonin value of 0.38 nanograms per millilitre provided a sensitivity of 70% with 95% confidence intervals from 39 to 89 for a specificity of 52% with 95% confidence intervals from 34 to 68. After the third post-operative day, a second assay at a 24-hour interval can improve the sensitivity of the test. CONCLUSIONS: Procalcitonin seems to be a discriminating marker of bacterial infection during the post-operative days following cardiopulmonary bypass in children.

[Study on the integration of mental health support into primary health care in Guinea]. / Expérience d´intégration de la santé mentale en première ligne de soins en Guinée.

INTRODUCTION: the low coverage of specialized mental health services and the shortage of human resources for mental health are enormous challenges for the health care system in Africa. The integration of mental health support into primary health care is a substantial and feasible complementary intervention to specialized services. We collected and analyzed data from 5 Health Care Centers (HCC) that had integrated this care package in Guinea. METHODS: we conducted a descriptive study of new cases of mental health issues between 2012 and 2017. The reasons for consultations and diagnoses were identified and analyzed on the basis of consultation registries and individual medical records. RESULTS: a total of 4.995 patients with mental health problems received consultations (2.8% of general consultations; 0.5 -7.7% according to the centers). The average age of patients was 27,9 years (± 16.1). The most common reasons for consultations were: insomnia 44.4% (n = 2081), seizures 39% (n = 1827), behavioral disorders 31.9% (n = 1263) and hallucinations 26.1% (n = 1224). The most common diagnoses were: epilepsy 36.8% (n = 1773) and psychotic disorders 33.5% (n = 1613). Eighty eight point four per cent (n = 4418) of patients received medical treatment, most often combined with psychological support. CONCLUSION: this study highlights that in the Guinean context, where access to specialized mental health care is very limited, patients with mental ill, even with severe medical conditions, can be followed up in the health centers by non-specialized but trained mental health professionals.

[Sclerosing encapsulating peritonitis: current features]. / La sclérose péritonéale encapsulante: aspects actuels.

We report three original cases of sclerosing encapsulating peritonitis (SEP) which is a rare but severe complication of peritoneal dialysis (PD). In the report of case 1, SEP occurred in a 75-year-old diabetic patient mellitus 18 years after the arrest of PD technique recurrent infectious peritonitis. The switch to hemodialysis was associated with a chronic inflammatory state poorly explained until the discovery of SEP. For case 2, SEP started within seven months after automated PD initiation in a severe septic context leading to leg amputation in a 57-year-old unstable diabetic male. In the last case, 84-year-old woman presented SEP after several peritonitis episodes, including one due to acute pancreatitis. In all cases, SEP was confirmed by open surgery. All patients were treated by visceralysis. The outcome was favorable in two of these three patients. SEP mechanisms, risks factors, prognosis and treatment are discussed with reference to the literature.

Using detachment-promoting agents for the prevention of chronic peritoneal dialysis-associated infections.

Biofilms are known to be responsible for chronic peritoneal dialysis (PD)-related infections. Such infections are still frequent among patients in PD. The aim of this study was to develop a new approach in the prevention of chronic PD-related infection by regular injection of specific formulations containing detachment-promoting agents. A biofilm reactor system reproducing PD-like operating conditions was developed. A first set of experiments allowed the assessment of the anti-biofilm efficacy of various formulations. Then, experiments were performed for a longer duration and selected formulations were tested and compared with taurolidine. Biofilm removal was quantified by calculating the percentage of coverage reduction compared with an untreated control. A regular weekly treatment led to a 97% reduction of the surface coverage although a daily treatment with taurolidine still left 48% of the biomass on the surface. Such treatment is recommended to reduce the frequencies of chronic PD-related infections.

Multifaceted intervention to improve obstetric practices: The OPERA cluster-randomized controlled trial.

OBJECTIVE: Suboptimal care contributes to perinatal morbidity and mortality. We investigated the effects of a multifaceted program designed to improve obstetric practices and outcomes. STUDY DESIGN: A cluster-randomized trial was conducted from October 2008 to November 2010 in 95 French maternity units randomized either to receive an information intervention about published guidelines or left to apply them freely. The intervention combined an outreach visit with a morbidity/mortality conference (MMC) to review perinatal morbidity/mortality cases. Within the intervention group, the units were randomized to have MMCs with or without clinical psychologists. The primary outcome was the rate of suboptimal care among perinatal morbidity/mortality cases. The secondary outcomes included the rate of suboptimal care among cases of morbidity, the rate of suboptimal care among cases of mortality, the rate of avoidable morbidity and/or mortality cases, and the incidence of, morbidity and/or mortality. A mixed logistic regression model with random intercept was used to quantify the effect of the intervention on the main outcome. RESULTS: The study reviewed 2459 cases of morbidity or mortality among 165,353 births. The rate of suboptimal care among morbidity plus mortality cases was not significantly lower in the intervention than in the control group (8.1% vs. 10.6%, OR [95% CI]: 0.75 [0.50-1.12], p=0.15. However, the cases of suboptimal care among morbidity cases were significantly lower in the intervention group (7.6% vs. 11.5%, 0.62 [0.40-0.94], p=0.02); the incidence of perinatal morbidity was also lower (7.0 vs. 8.1‰, p=0.01). No differences were found between psychologist-backed and the other units. CONCLUSIONS: The intervention reduced the rate of suboptimal care mainly in morbidity cases and the incidence of morbidity but did not succeed in improving morbidity plus mortality combined. More clear-cut results regarding mortality require a longer study period and the inclusion of structures that intervene before and after the delivery room. (ClinicalTrials.gov ID: NCT02584166).

Review in depth and meta-analysis of controlled trials on colorectal cancer screening by faecal occult blood test.

BACKGROUND: Several randomized studies have shown that colorectal cancer (CRC) screening by faecal occult blood test (FOBT) reduces CRC mortality. These trials have different designs, especially concerning FOBT frequency and duration, as well as the length of follow-up after stopping FOBT campaigns. AIMS: To review the effectiveness of screening for CRC with FOBT, to consider the reduction in mortality during or after screening or to identify factors associated with a significant mortality reduction. METHODS: A systematic review of trials of FOBT screening with a meta-analysis of four controlled trials selected for their biennial and population-based design. The main outcome measurements were mortality relative risk (RR) and 95% confidence interval (CI) of biennial FOBT during short (10 years, i.e. five or six rounds) or long-term (six or more rounds) screening periods, as well as after stopping screening and follow-up during 5-7 years. The meta-analysis used the Mantel-Haenszel method with fixed effects when the heterogeneity test was not significant, and used 'intent to screen' results. RESULTS: Although the quality of the four trials was high, only three were randomized, and one used rehydrated biennial FOBT associated with a high colonoscopy rate (28%). A meta-analysis of mortality results showed that subjects allocated to screening had a reduction of CRC mortality during a 10-year period (RR 0.86; CI 0.79-0.94) although CRC mortality was not decreased during the 5-7 years after the 10-year (six rounds) screening period, nor in the last phase (8-16 years after the onset of screening) of a long-term (16 years or nine rounds) biennial screening. Whatever the design of the period of ongoing FOBT, CRC incidence neither decreased nor increased, although it was reduced for 5-7 years after the 10-year screening period. Neither the design nor the clinical or demographic parameters of these trials were independently associated with CRC mortality reduction. CONCLUSION: Biennial FOBT decreased CRC mortality by 14% when performed over 10 years, without evidence-based benefit on CRC mortality when performed over a longer period. No independent predictors of CRC mortality reduction have been identified in order to allow a CRC screening programme in any subgroups of subjects at risk.

[Cost-effectiveness of colorectal cancer screening]. / Coût-efficacité du dépistage du cancer colorectal.

Colorectal cancer (CRC) screening in France is based on a faecal occult blood test every two years in average risk subjects 50-74 years of age while other endoscopic or non-endoscopic screening methods are used in Europe and in the USA. Beside the reduced incidence of and mortality from CRC found in available studies, cost-effectiveness data need to be taken into account. Because of the delay between randomized controlled trials and clinical results, transitional probabilistic models of screening programs are useful for public health policy makers. The aim of the present review was to promote the implementation of cost-effectiveness studies, to provide a guide to analyze cost-effectiveness studies on CRC screening and, to propose a French cost effectiveness study comparing CRC screening strategies. Most of these trials were performed by US or UK authors and demonstrate that the incremental cost-effectiveness ratio varies between 5 000 and 15 000 US dollars/one year life gained, with wide variations: these results were highly dependent on the unit costs of the different devices as well as the predictive values of the screening tests. Although CRC screening programs have been implemented in several administrative districts of France since 2002, and the results of these randomized controlled trials using fecal occult blood have been updated, cost-effectiveness criteria need to be integrated; especially since the results of screening campaigns based on other tools such as flexible sigmoidoscopy should be available in 2007.

Neonatal EEG and neurodevelopmental outcome in preterm infants born before 32†weeks.

OBJECTIVE: To assess the value of neonatal EEG for predicting non-optimal neurodevelopmental outcomes in very preterm infants, using a multimodal strategy of evaluation comprising brain imaging and clinical assessment. DESIGN AND SETTING: Between 2003 and 2009, we performed an observational, population-based study. Out of 2040 eligible preterm infants born before 32 weeks, 1954 were enrolled in the French regional Loire Infant Follow-Up Team (LIFT) cohort. 1744 (89%) of these completed the follow-up. Neonatal EEGs were recorded prospectively as two EEGs during the first 2 weeks of life and then one every 2 weeks up to 33 weeks. MAIN OUTCOME MEASURES: The neurodevelopmental outcome was assessed by physical examination, the Brunet-Lézine Test and/or the Age and Stages Questionnaire at 2 years of corrected age. RESULTS: Of the 1744 infants assessed at 2 years, 422 had a non-optimal outcome. A total of 4804 EEGs were performed, and 1345 infants had at least one EEG. EEG abnormalities were predictive of non-optimal outcomes after controlling for confounding factors such as severe intracranial lesions detected by brain imaging. Transient moderate and severe abnormalities were independent predictors of non-optimal outcomes with an OR and 95% CI of 1.49 (1.08 to 2.04) and 2.38 (1.49 to 3.81), respectively. In the validation group, the predictive risk stratification tree identified severe abnormalities as a factor contributing to the prognosis of two subgroups: infants with severe cranial lesions and infants with a normal examination at discharge and without severe cranial lesions.

Long-term outcome of localized high-grade non-Hodgkin's lymphoma treated with high dose CHOP regimen and involved field radiotherapy: results of a GOELAMS study.

BACKGROUND AND OBJECTIVES: Most patients with localized high-grade non-Hodgkin's lymphoma (NHL) can be cured with or without adjuvant radiotherapy. However few data are available on the long-term outcome of these patients. Here we report the results of a prospective study, started in 1984, which was conducted to evaluate the long-term outcome of patients with localized high-grade NHL. DESIGN AND METHODS: In this multicenter, prospective study by the GOELAMS group, 253 patients with localized high-grade NHL were treated with 3 cycles of vindesine, cyclophosphamide, adriamycin and prednisone (VCAP, a high-dose CHOP regimen) followed by involved field radiotherapy (40 Gy). RESULTS: After completion of chemotherapy, 213 patients (84%) entered complete remission (CR) and 30 (12%) obtained a partial remission. Treatment failed in 6 patients (2.5%) and there were 4 toxic deaths (1.5%). Following radiotherapy, 239 (94%) of all patients were in CR. With a median follow-up of 88 months, overall survival and disease-free survival rates were 84% and 85% respectively at five years, and 78% and 82% respectively at ten years. The response to chemotherapy was decisive to survival. We observed 43 relapses (17%) at a median time of 20 months after CR, and 9 patients relapsed after five years. Eleven patients (3%) developed another malignancy in the follow-up period. INTERPRETATION AND CONCLUSIONS: High-dose CHOP followed by locoregional radiotherapy is a feasible treatment for localized high-grade NHL. It has very few complications, a good CR rate and the OS is 78% at 10 years.

RBC 6-TGN and hematological parameters in patients with Crohn's disease treated by azathioprine.

OBJECTIVE: The immunosuppressive properties of azathioprine (AZA) are mediated by intracellular metabolism of 6-MP into its active metabolites 6-thiguanine nucleotide (6-TGN) and 6-methylmercaptopurine (6-MMP). The aims of this study were to correlate red blood cell (RBC) 6-TGN and hematological parameters and their change in adult patients with Crohn's disease (CD) treated by AZA and to determine independent factors enabling determination of RBC 6-TGN. METHODS: RBC 6-TGN concentration was determined with high performance liquid chromography (HLPC) performed on 74 hepa-rinized blood samples from 32 patients. Changes of hematological parameters were measured for each RBC 6-TGN concentration. RBC 6-TGN concentration above 235 pmol/8x108 RBC was proposed as the therapeutic level in patients treated by AZA. Correlations between the various parameters were assessed as appropriate. Logistic regression analysis was used to determinate independent variables. P<0.05 was considered significant. RESULTS: There was a positive correlation between RBC 6-TGN and decreased red cell count (DeltaRBC) (r=0.314; P=0.006), platelet count (DeltaPlatelets) (r=0.314; P=0.007), White cell count (DeltaWC) (r=0.241; P=0.04) and neutrophil count (DeltaPMN) (r=0.292; P=0.02). RBC 6-TGN in the therapeutic zone was positively correlated with mean corpuscular volume (MCV) (r=0.527; P=0.01), mean corpuscular hemoglobin concentration (MCHC) (r=0.437; P=0.04), increase in MCV (DeltaMCV) (r=0.512; P=0.012), decrease in White cell count (DeltaWC) (r=0451; P=003) and in neutrophil count (DeltaPMN) (r=0.463; P=0.03). Multivariate analysis showed that low activity of CD (P<0.02), young age at onset of treatment by AZA (P<0.03) and a low red cell distribution width (RDW) (P=0.003) were independent factors for RBC 6-TGN situated in therapeutic zone. RBC 6-TGN could be determined by logistic regression from AZA dose (mg/kg/d) and MCV increase. CONCLUSION: This study confirms that hematological parameters or their change can be used to determine whether RBC 6-TGN concentration has reached the therapeutic level. Logistic regression analysis showed that decreased RDW and increased MCV were independent factors for RBC 6-TGN level.

Predictive value of the parent-completed ASQ for school difficulties in preterm-born children <35 weeks' GA at five years of age.

BACKGROUND: Preterm infants are at greater risk of developmental impairment and require close follow-up for early and optimal care. OBJECTIVES: The objective of the present study was to determine from which age the parental Ages and Stages Questionnaire (ASQ) allows detection of school difficulties in preterm children <35 weeks' gestational age. METHODS: Preterm children from the regional Loire Infant Follow-up Team network were evaluated with the Global School Adaptation (GSA) assessment tool at 5 years of age and at least one parental-completed ASQ at 18, 24, or 36 months. Children belonging to the first decile of the GSA score (<38) were considered to have severe school difficulties. Using overall ASQ scores as continuous variables, receiver operating characteristic (ROC) curves were generated at every age in order to identify preterm children with severe school difficulties. RESULTS: GSA scores were obtained in 1,775 infants at 5 years of age, and at least one ASQ score at 18, 24, or 36 months was completed. Upon ROC analysis, we observed that the 18-, 24-, and 36-month ASQ scores produced respective area under the ROC curve values of 0.66 (0.64-0.69), 0.72 (0.70-0.75), and 0.77 (0.75-0.80) for predicting a GSA score in the first decile. An ASQ cutoff value of 255 at 36 months showed optimal discriminatory power for identifying significant school difficulties at 5 years of age. CONCLUSIONS: The 36-month ASQ is a simple and cost-effective tool that can be employed to help predict future severe school difficulties at 5 years of age in preterm-born children.

Characterizing early detection of language difficulties in children born preterm.

BACKGROUND: The optimal age for assessing language difficulties in premature children remains unclear. AIMS: To determine the most predictive and earliest screening tool for later language difficulties on children born preterm. STUDY DESIGN: A prospective population-based study in the Loire Infant Follow-up Team LIFT SUBJECTS: All children born <35weeks of gestation between 2003 and 2005 were assessed at corrected ages by four screening tools: the Ages & Stages Questionnaire (ASQ) communication scale at 18 and 24months, the language items of Brunet Lezine test at 24months, and the "Epreuves de Repérage des Troubles du Langage" (ERTL) at 4years. OUTCOME MEASURES: After 5years, the kindergarten teacher evaluated the vocabulary, grammar and pronunciation capacities of the child in comparison with the classroom performances. RESULTS: Among 1957 infants enrolled at discharge, 947 were assessed by their teacher with 12.2% (n=116) of language difficulties. Full data at all time points were available for 426 infants. The area under curve of the receiver operator characteristic curve obtained for the ASQ communication scale at 18months was significantly lower (0.65±0.09) than that obtained at 24months (0.77±0.08) and the languages items of Brunet Lezine test at 24months (0.77±0.08), and the ERTL at 4years (0.76±0.09). The optimal cut-off value for ASQ communication at 24months is ≤45 [sensitivity of 0.79 (95%CI: 0.70-0.86); specificity of 0.63 (95%CI: 0.59-0.66)]. CONCLUSIONS: The Ages & Stages Questionnaire communication scale at 24 corrected months appears as an acceptable test at an early time point to identify preterm children at risk of later language difficulties.

Quality indicators for continuous monitoring to improve maternal and infant health in maternity departments: a modified Delphi survey of an international multidisciplinary panel.

OBJECTIVE: Measuring the quality of inpatient obstetrical care using quality indicators is becoming increasingly important for both patients and healthcare providers. However, there is no consensus about which measures are optimal. We describe a modified Delphi method to identify a set of indicators for continuously monitoring the quality of maternity care by healthcare professionals. METHODOLOGY AND MAIN FINDINGS: An international French-speaking multidisciplinary panel comprising 22 obstetricians-gynaecologists, 12 midwives, and 1 paediatrician assessed potential indicators extracted from a medical literature search, using a two-round Delphi procedure followed by a physical meeting. Each panellist rated each indicator based on validity and feasibility. In the first round, 35 panellists from 5 countries and 20 maternity units evaluated 26 indicators including 15 related to the management of the overall population of pregnant women, 3 to the management of women followed from the first trimester of pregnancy, 2 to the management of low-risk pregnant women, and 6 to the management of neonates. 25 quality indicators were kept for next step. In the second round, 27 (27/35: 77%) panellists selected 17 indicators; the remaining 8 indicators were discussed during a physical meeting. The final set comprised 18 indicators. CONCLUSION: A multidisciplinary panel selected indicators that reflect the quality of obstetrical care. This set of indicators could be used to assess and monitor obstetrical care, with the goal of improving the quality of care in maternity units.

Neurological assessment of preterm infants for predicting neuromotor status at 2 years: results from the LIFT cohort.

OBJECTIVE: To develop a predictive risk stratification model for the identification of preterm infants at risk of 2-year suboptimal neuromotor status. DESIGN: Population-based observational study. SETTING: Regional preterm infant follow-up programme (Loire Infant Follow-up Team (LIFT) cohort) implemented in 2003. PARTICIPANTS: 4030 preterm infants were enrolled in the LIFT cohort, and examined by neonatologists using a modified version of the Amiel-Tison neurological assessment tool. MAIN OUTCOME CRITERIA: 2 year neuromotor status based on clinical examinations was conducted by trained paediatricians and parents' responses to the Ages and Stages Questionnaire were reported. RESULTS: At 2 years of corrected age, 3321 preterm infants were examined, and suboptimal neuromotor status was found in 355 (10.7%). The study population was divided into training and validation sets. In the training set, 13 neonatal neurological items were associated with a 2-year suboptimal neuromotor status. Having at least one abnormal item was defined as an abnormal neurological status at term. In the validation set, these data predicted a 2-year suboptimal neuromotor status with a sensitivity of 0.55 (95% CI 0.47 to 0.62) and a specificity of 0.65 (95% CI 0.62 to 0.67). Two predictive risk stratification trees were built using the training set, which were based on the neurological assessment at term along with either gestational age or severe cranial lesions or birth weight. Using the validation set, the first tree identified a subgroup with a relatively low risk of suboptimal neuromotor status (3%), representing 32% of infants, and the second tree identified a subgroup with a risk of 5%, representing 42% of infants. CONCLUSION: A normal neurological assessment at term allows the identification of a subgroup of preterm infants with a lower risk of non-optimal neuromotor development at 2 years.
