[Approach of the spiritual dimension through the nursing care interview in oncohaematology]. / Approche de la dimension spirituelle par l'entretien de relation d'aide infirmière en oncohématologie.

Responding to the existential questions of patients faced with a serious hematological disease does not go without saying for a caregiver not trained for this purpose. It is however essential to accompany them in this tragic moment of their life. The research project here aims to develop a process of relational and spiritual care to best meet their quest.

Anxious and depressive symptoms in Parkinson's disease: the French cross-sectionnal DoPaMiP study.

Anxiety has been less extensively studied than depression in Parkinson's disease (PD). The DoPaMiP survey allowed assessing simultaneously anxiety and depressive symptoms in PD and comparing correlations of both symptoms with clinical and therapeutic features of the disease. Cross sectional survey conducted prospectively in 450 ambulatory nondemented PD patients and 98 patients with other disorders than PD. Anxiety and depressive symptoms were assessed using the Hospital Anxiety and Depression Scale (HADS), parkinsonism using the Unified Parkinson's Disease Rating Scale (UPDRS). Other clinical factors were measured using a structured standardized examination/questionnaire. The mean HADS-A (anxiety) subscore was higher in PD patients than in the others (8.2 +/- 3.9 vs. 6.5 +/- 3.2, P < 10(-4)) as was the HADS-D (depressive) subscore (6.6 +/- 3.8 vs. 3.9 +/- 3.2, P < 10(-4)). Patients with possible/probable anxious signs (HADS-A >or= 8) were more prevalent in PD (51% vs. 29%, P < 10(-4)) as were those with depressive symptoms (40% vs. 10%, P < 10(-4)). Conversely, anxiolytic and antidepressant medications consumption was not different between the 2 groups. Patients with anxious symptoms were more frequently female and younger than those without such symptoms, while those with depressive symptoms had more severe indices of parkinsonism, more comorbidities and lower cognitive function (Mini Mental State Exam). The logistic regression model revealed that patients with depressive symptoms received more frequently levodopa and less frequently a dopamine agonist. Anxiety and depressive symptoms were more frequent in PD patients than in medical control group. Both symptoms were commonly associated in the same PD patients, but were correlated with different clinical/therapeutic features, suggesting different underlying pathophysiological mechanisms.

Improving attitudes towards children with disabilities in a school context: a cluster randomized intervention study.

AIM: although inclusive education of disabled children is now an accepted practice, it is often challenged by negative peer attitudes. We undertook an interventional study aimed at improving students' attitudes towards their disabled peers. METHOD: the participants were students from the 7th grade of twelve paired schools (1509 students from 62 classes; age 12-13y), randomly allocated to an intervention group (205 males, 285 females) or a control group (132 males, 165 females). The intervention consisted of a mandatory comprehensive educational project on disability. The Chedoke-McMaster Attitudes Towards Children with Handicaps Scale (CATCH) was used to assess children's attitudes before (T0) and after (T1) intervention. The hierarchical structure of the data was taken into account by adjusting standard deviations and using linear multilevel models. RESULTS: seven hundred and eighty-four students had at least one score on the three domains (cognitive, affective, behavioural) of the CATCH at T0 and T1. The final scores were higher than baseline scores (total scores, intervention group: baseline score 25.6 (SD=5.4), final score 26.8 (5.9), p<0.001; CONTROL GROUP: baseline 25.2 (5.4), final 26.0 (5.7), p<0.009) with no significant difference between the intervention and control groups. Individual score changes over time were associated with baseline score (p<0.001 for total and all sub-scores). Lower improvement in attitudes was found in students from schools with special units for their peers with cognitive impairment for total (p=0.013), affective (p<0.001), and behavioural (p=0.001) scores, while higher improvement existed for the cognitive domain (p=0.029). INTERPRETATION: although we found no effect of our intervention, we found an improvement in attitudes in the intervention and control groups that could be a result of the nature of the scales and questionnaires the students had to complete before the intervention.

Determinants of students' attitudes towards peers with disabilities.

AIM: To explore factors associated with students' attitudes towards their peers with disabilities. METHOD: All 7th grade students (aged 12-13y) from 12 schools in the Toulouse area were invited to participate (n=1509). Attitudes were measured using the Chedoke-McMaster Attitudes Towards Children with Handicaps (CATCH) questionnaire (affective, behavioural, cognitive, and total scores). Personal characteristics, including KIDSCREEN quality of life scores, were recorded. Data regarding information about disabilities received from parents and the media and acquaintance with people with disabilities constituted the 'disability knowledge' factors. The characteristics of the schools were obtained from the local education authority. Multivariate multilevel linear regression analyses were conducted to explore the associations between CATCH scores and these three groups of factors. RESULTS: Responses from 1135 students (612 females, 523 males; mean age 12y 8mo SD 7mo; age range 10y 8mo-15y) were studied (75.2% of the students approached). Factors independently associated with more positive attitudes were being a female, having a good quality of life, being friends with a child with disabilities, or having received information about disabilities from parents and the media. Presence in the school of a special class for children with cognitive disabilities was independently associated with more negative attitudes. INTERPRETATION: This cross-sectional study identified different personal and environmental factors upon which interventions aimed at improving students' attitudes towards their peers with disabilities could be based.

Children's enduring PTSD symptoms are related to their family's adaptability and cohesion.

This study compared, 18-24 months after an industrial disaster, in two groups of children (those with clinically relevant PTSD symptoms versus those with low PTSD symptoms), the child's perception of family cohesion and adaptability, the child's experience of the explosion, and parental characteristics. Enmeshed family cohesion or rigid family adaptability were more frequently found in children with low PTSD symptoms. PTSD symptoms in the mother, living in a family of 3 or more children, and being female were significantly associated with PTSD symptoms in the children. The assessment of traumatized children should include assessment of family's adaptability and cohesion.

Chronic pain in Parkinson's disease: the cross-sectional French DoPaMiP survey.

Pain is a frequent, but poorly studied symptom of Parkinson's disease (PD). DoPaMiP survey aimed to assess the prevalence of chronic pain in PD, to describe PD patients with chronic pain, and to record analgesic consumption. About 450 parkinsonian patients underwent structured standardized clinical examination and completed self-reported questionnaires in a cross sectional survey. Pains related or unrelated to PD were identified according to predefined criteria. About 98 patients with other chronic disorders than PD were examined to assess if pain was more frequent in PD than in this population. Two thirds parkinsonian patients (278 of 450) had chronic pain. Twenty-five patients with non-chronic pain (<3-month duration) were excluded from subsequent analysis. Twenty six percent (111 of 425) parkinsonian patients had pain unrelated to PD ("non-PD-pain", caused mainly by osteoarthritis), while 39.3% (167 of 425) had chronic pain related to PD ("PD-pain"). In this last group, PD was the sole cause of pain in 103 and indirectly aggravated pain of another origin (mainly osteoarthritis) in 64. Parkinsonian patients with "PD-pain" were younger at PD onset, had more motor complications, more severe depressive symptoms than those without pain or with "non-PD pain." "PD-pain" was more intense (P = 0.03), but was less frequently reported to doctors (P = 0.02), and was associated with less frequent analgesic consumption than "non-PD-pain." Pain was twice more frequent in PD patients than in patients without PD after adjustment for osteo-articular comorbidities (OR = 1.9; 95% CI 1.2-3.2). Chronic pain is frequent but underreported in PD. Awareness of this problem should be increased and the assessment of analgesic strategies improved.

Factors associated with overweight in preschool-age children in southwestern France.

BACKGROUND: Pediatric overweight and obesity are becoming an epidemic worldwide, which indicates the need for formulating preventive programs and policies during a child's early years. OBJECTIVE: We identified factors associated with overweight in young children in southwestern France. DESIGN: Children [n = 1780; x (+/-SD) age: 3.9 +/- 0.4 y] were recruited in kindergarten. Medical information on the parents, grandparents, and child as well as the child's 3-d dietary intake, participation in organized sports, and television-viewing habits were ascertained, and anthropometric measurements of the child were taken. RESULTS: The prevalence of overweight was 9.1% when using body mass index >or= 90th percentile of French reference curves as a cutoff. In a multivariate logistic regression, overweight at 4 y was associated with female sex, having an overweight mother, and having >or=1 diabetic grandparent; odds ratios (ORs; 95% CIs) for these variables were 1.9 (1.2, 3.0), 2.2 (1.0, 4.7), and 2.6 (1.6, 4.1), respectively. Being small or large for gestational age was not associated with the risk of overweight at 4 y, whereas this risk was increased for children who were overweight at 9 or 24 mo: ORs (95% CIs) were 4.0 (2.4, 6.9) and 11.7 (6.1, 22.2), respectively. Nutrient intakes did not differ significantly with weight status in girls; however, overweight boys had significantly greater energy and lipid intakes than did their nonoverweight counterparts. Overweight was positively associated with television viewing (>1 h/d) in both sexes and with participation in organized sports in girls only. CONCLUSIONS: A family history of overweight or diabetes, overweight in the first 2 y of life, and television viewing are associated with overweight at 4 y. These factors should be considered in developing programs for the prevention of overweight in early childhood.

Outcome of Alzheimer's disease: potential impact of cholinesterase inhibitors.

BACKGROUND: Alzheimer's disease is fast becoming a major public health concern with serious economic consequences. The cholinesterase inhibitors (CEIs) offer some benefit in the symptomatic treatment of the disease. This study aims to investigate the effect of CEIs on three clinically relevant domains (rapid cognitive decline, institutionalization, and weight loss) in patients with Alzheimer's disease. METHODS: A prospective observational study was performed in which a population of 455 Alzheimer's disease patients were recruited and followed up for at least 1 year between 1994 and 2002. Patients were reevaluated at 6 monthly intervals using standardized neurocognitive and geriatric evaluations in addition to complete clinical examination, standard paraclinical investigations, and recording of treatment received. RESULTS: The risk of rapid cognitive deterioration was significantly decreased in patients taking CEIs for at least 1 year compared to untreated patients (odds ratio [OR]=0.56, 95% confidence interval [CI], 0.34-0.93; p=.025). The potential benefit of CEI use was also found on institutionalization (OR=0.2, 95% CI, 0.08-0.48; p<.001) and weight loss (OR=0.56, 95% CI, 0.32-0.97; p=.039) after 1 year of follow-up. CONCLUSION: The special interest of this study is that all patients were recruited and followed in the same center with the same management care plan and the same medical team. This follow-up offers us a unique opportunity to compare the 1-year evolution of the disease in clinical practice before and after the marketing of CEIs and allows us to demonstrate a clinically significant improvement in patient outcome over time.

Iris-supported phakic lenses (rigid vs foldable version) for treating moderately high myopia: randomized paired eye comparison.

PURPOSE: To compare refractive performance of Artisan (Ophtec, Groningen, The Netherlands) or Verisyse phakic intraocular lens and its foldable version, Artiflex (Ophtec), for the correction of moderately high myopia. DESIGN: Randomized pilot study. METHODS: setting: Institutional practice. patient population: Thirty-one patients with myopia that ranged from -6 to -14 diopters (D). interventional procedure: One eye was implanted with an Artisan phakic intraocular lens (PIOL) and the other with an Artiflex PIOLs. main outcome measures: Primary outcome measure was the percentage of eyes with uncorrected visual acuity (UCVA) of >20/40 at one year after the operation. Main secondary outcome measures were the safety index, the change of two lines or more of best spectacle-corrected visual acuity (BSCVA) and the endothelial cell count. RESULTS: No intraoperative complications were noticed. One year after surgery, the percentage of eyes with UCVA of >20/40 was 51.6% (16/31 patients) for Artisan-treated eyes and 77.4% (24/31 patients) for Artiflex-treated eyes (P = .033). One month after surgery, this same percentage was 42.9% (13/31 patients) and 77.4% (24/31 patients), respectively (P = .004). The safety index at one year was 1.13 +/- 0.24 for Artisan-treated eyes and 1.12 +/- 0.21 for Artiflex-treated eyes, which is a difference that was not statistically significant (P = 0.742). At one year after surgery, the changes of two lines or more of BSCVA and the endothelial cell loss were similar for both groups. CONCLUSION: To correct moderately high myopia, the Artiflex lens provides a faster visual recovery and a better UCVA than does the Artisan lens. The safety of the lens should be supported by an enlarged sample size and a longer follow-up period.

Cognitive impairment and composition of drinking water in women: findings of the EPIDOS Study.

BACKGROUND: The concentration of aluminum or silica in drinking water may be a potential environmental risk factor for Alzheimer disease (AD). OBJECTIVES: The objective was to investigate at baseline the potential association between the composition of drinking water and the level of cognitive function in women taking part in the Epidemiology of Osteoporosis (EPIDOS) Study and to determine during follow-up the effects of the composition of drinking water on the risk of AD. DESIGN: Women aged >/=75 y (n = 7598) were recruited between 1992 and 1994 in 5 geographic areas of France. The participants from one center (n = 1462) were followed for

Muscle strength in obese elderly women: effect of recreational physical activity in a cross-sectional study.

BACKGROUND: Muscle strength (MS) may be impaired in obese persons, and this impairment may be a consequence of both obesity and low physical fitness. OBJECTIVE: We investigated whether MS differed between obese [body mass index (BMI; in kg/m2 > 29], normal-weight (BMI = 24-29), and lean (BMI < 24) elderly subjects and compared the MS of sedentary and active subjects according to their BMI group. DESIGN: The study included 215 obese [ (+/- SD) age: 80.0 +/- 3.5 y; BMI: 31.9 +/- 2.6], 630 normal-weight (age: 80.2 +/- 3.7 y; BMI: 26.3 +/- 1.4), and 598 lean (age: 80.7 +/- 3.5 y; BMI: 21.6 +/- 1.8) women with good functional ability. A cross-sectional design was used. Anthropometric measures (weight, height); measures of appendicular skeletal muscle mass (by dual-energy X-ray absorptiometry), isometric knee and elbow extension (by statergometer), and isometric handgrip strength (by dynamometer); and data on health status and self-reported recreational physical activity (RPA: walking, gymnastics, cycling, swimming, gardening) were collected. RESULTS: Absolute (unadjusted) MS was higher in obese than in lean women (P < 0.01), except for handgrip strength (P > 0.05). When adjusted for age, height, RPA, pain, depression, and appendicular skeletal muscle mass, MS did not differ significantly between obese, normal-weight, and lean subjects, except for knee extension (significant interaction effect with RPA; P = 0.01). With increasing BMI, lower limb strength did not change in the sedentary women but increased in active (> or = 1 h/wk in > or = 1 RPA for > or = 1 mo) women. All adjusted MS measures in active participants were significantly higher (P < 0.001) than those in their sedentary peers. CONCLUSION: The adjusted MS of elderly women is not associated with obesity but is higher in active subjects than in sedentary ones, especially in the lower limbs of obese subjects.

Body composition in French women 75+ years of age: the EPIDOS study.

BACKGROUND: There are presently no published data on age-related changes in body composition in French individuals older than 65 or 80 years. This paper presents a cross-sectional study of 7518 community-residing French women older than 75 years. METHODS: We examined age differences changes in body composition and anthropometry between age groups (76-80, 81-85, and 86-95 years of age). Whole body composition was estimated using a dual energy X-ray absorptiometry (DXA) scanner. Measurements of appendicular skeletal muscle (ASM) mass and sarcopenia were performed for a subsample of 1321 women. RESULTS: Significant age differences exist in total fat mass and total bone mineral content in elderly women between 76 and 95 years of age. There was also a significant decreased in fat free soft tissue mass from 76 to 85. The decline in fat free mass may be reduced over 85 years of age. The prevalence of low muscle mass, or sarcopenia, increased with age from 8.9 in 76-80 to 10.9% in 86-95 age group, but the difference was not statistically significant. CONCLUSIONS: Interventional programs developed to prevent or reduce sarcopenia would have a better influence on population under 85 years, i.e. when the decline in ASM mass is the most severe. Others longitudinal studies could be performed to confirm our results.

Comparison of bone mineral density and body composition measurements in women obtained from two DXA instruments.

Information is lacking regarding the comparison of bone mineral and body composition measurements obtained from the different dual energy X-ray absorptiometry (DXA) systems. The purpose of this study is to compare body composition and whole body bone mineral density (BMD) measurements from the hologic QDR-4500 W (DXA H) and the lunar (DXA L) systems. Seven women older than 40 years of age, were scanned on the same day by using DXA H and DXA L by the same observer. Measured total fat mass, percentage fat, whole body fat free soft tissue mass and BMD were similar between machines, but body mass was significantly higher with DXA L than with DXA H (P=0.0156). This was due to a higher bone mineral content obtained with DXA L. Agreement between the two DXA systems was quantified by using the Bland and Altman method. For each variable, all pairs of measurements were within the 95% confidence limits. These results suggested that we could use the two measurement methods interchangeably. However, due to the bone mineral inter-machine differences, comparisons of DXA measurements from different machines should be interpreted with caution.

Is there a relationship between fat-free soft tissue mass and low cognitive function? Results from a study of 7,105 women.

OBJECTIVES: To test the hypothesis that low fat-free soft tissue mass and cognitive impairment are independently associated. DESIGN: Cross-sectional study. SETTING: Five geographic areas of France. PARTICIPANTS: Seven thousand one hundred five community-dwelling women aged 75 and older recruited from electoral rolls between 1992 and 1994. MEASUREMENTS: Fat-free soft tissue mass, body fat mass, and bone mineral density were measured using dual-energy x-ray absorptiometry. Study participants were assessed for cognitive impairment using the Short Portable Mental Status Questionnaire and divided into two groups according to their scores. Logistic regression models were used to calculate multivariate-adjusted differences in body composition between two groups of subjects according to their cognitive function. RESULTS: After adjustment for confounders, compared with women in the highest quartile of fat-free soft tissue mass, women in the lowest quartile had an odds ratio of 1.43 (95% confidence interval (CI) = 1.07-1.91) for cognitive impairment. Low fat mass was also associated with lower cognitive function, with an odds ratio of 1.35 (95% CI = 1.01-1.79) for the lower quartile of fat mass compared with the highest quartile. There was no association between cognitive impairment and bone mineral density. CONCLUSIONS: This finding supports the hypothesis that low muscle mass is associated with cognitive impairment in older women. These two components represent major causes of frailty and functional decline in older people and could have some common mechanisms. Nevertheless, these results do not predict the causal variable.

Sarcopenia, calf circumference, and physical function of elderly women: a cross-sectional study.

OBJECTIVES: To determine whether calf circumference (CC), related to appendicular skeletal muscle mass, can be used as a measure of sarcopenia and is related to physical function. DESIGN: Retrospective analysis of data from 1992 to 1994 of the European Patient Information and Documentation Systems Study. SETTING: Community setting in France. PARTICIPANTS: One thousand four hundred fifty-eight French women aged 70 and older without previous history of hip fracture were recruited from the electoral lists. MEASUREMENTS: Muscular mass was assessed using dual-energy x-ray absorptiometry (DEXA). CC was measured using a tape measure. Anthropometric measurements (height; weight; and waist, hip, and calf circumference), strength markers (grip strength), and self-reported physical function were also determined. Sarcopenia was defined (using DEXA) as appendicular skeletal muscle mass (weight (kg)/height (m2)) less than two standard deviations below the mean of a young female reference group. RESULTS: The prevalence of sarcopenia was 9.5%. CC was correlated with appendicular skeletal muscle mass (r = 0.63). CC under 31 cm was the best clinical indicator of sarcopenia (sensitivity = 44.3%, specificity = 91.4%). CC under 31 cm was associated with disability and self-reported physical function but not sarcopenia (defined using DEXA), independent of age, comorbidity, obesity, income, health behavior, and visual impairment. CONCLUSION: CC cannot be used to predict sarcopenia defined using DEXA but provides valuable information on muscle-related disability and physical function.

Association of Alzheimer's disease onset with ginkgo biloba and other symptomatic cognitive treatments in a population of women aged 75 years and older from the EPIDOS study.

BACKGROUND: Peripheral C4A treatment (cerebral and peripheral vasotherapeutics) and especially Ginkgo biloba extracts are prescribed for a number of symptoms, particularly memory impairment, in elderly patients. It is postulated that because of its pharmacological actions, this treatment could prevent the decline of cognitive function, but no studies have been published to date to test its efficacy in prevention of Alzheimer's disease. The potential association between use of C4A treatments, in particular EGb 761 (standardized Ginkgo biloba extracts), and dementia of the Alzheimer type was investigated. METHODS: A case-control study was nested in a cohort of 1462 community-dwelling elderly women aged over 75 years. Sixty-nine women with Alzheimer-type dementia were compared with 345 paired women whose cognitive function remained normal. This study involved women whose cognitive function was evaluated at baseline by use of Pfeiffer's test and whose medication history was taken. The onset of cognitive impairment was investigated over a 7-year follow-up period. In order to study the factors associated with the onset of dementia, the data concerning women with a score of > or = 8 on Pfeiffer's test at inclusion, indicating normal cognitive function, were analyzed. RESULTS: A multivariate analysis including potential confounding factors showed that fewer women who developed Alzheimer's dementia had been prescribed C4A treatment (including EGb 761) for at least 2 years (odds ratio = 0.31, 95% confidence interval = 0.12-0.82, p =.018). Figures for EGb 761 alone were similar but did not reach statistical significance (odds ratio = 0.38, 95% confidence interval = 0.08-1.76, p =.22). CONCLUSION: These results suggest that C4A treatment may reduce the risk of developing Alzheimer's dementia in elderly women. The potential preventive effect of C4A treatments, including EGb 761, requires further examination. To establish a causal relationship, these findings have to be confirmed with prospective studies.

Validation of the French version of the Child Post-Traumatic Stress Reaction Index: psychometric properties in French speaking school-aged children.

BACKGROUND: Although the reliable and valid Child Post-Traumatic Stress Reaction Index (CPTS-RI) is a widely used measure of posttraumatic stress disorder (PTSD) symptoms in children, it has not been validated in French-speaking populations. The present study aims to assess the psychometric properties of the CPTS-RI in three samples of French-speaking school-children. METHODS: Data was obtained from three samples. Sample 1 was composed of 106 children (mean (SD) age = 11.7(0.7), 50% females) victims of an industrial disaster. Sample 2 was composed of 50 children (mean (SD) age = 10.8(2.6), 44% females) who had received an orthopaedic surgical procedure after an accident. Sample 3 was composed of 106 children (mean (SD) age = 11.7(2.2), 44% females) admitted to an emergency department after a road traffic accident. We tested internal consistency using Cronbach's alpha. We examined test-retest reliability using intraclass correlation coefficient. In order to assess the convergent validity of the French version of the CPTS-RI and the Clinician Administered PTS Scale-Child and Adolescent (CAPS-CA), spearman-correlation coefficient was computed. To verify the validity of the cut-off scores, a ROC curve was constructed which evaluated the sensitivity and specificity of each score compared to the diagnosis with the CAPS-CA. We also used principal components analysis with varimax rotation to study the structure of the French version of the CPTS-RI. RESULTS: Cronbach's alpha coefficient was 0.87 for the French version of the CPTS-RI. Two-week test-retest intraclass correlation coefficient (n = 30) was 0.67. The French version of the CPTS-RI was well correlated with the CAPS-CA (r = 0.76, p < 0.001). Taking the CAPS-CA as the diagnostic reference, with a diagnostic cut-off of >24 for the CPTS-RI, the sensitivity and specificities were 100% and 62.6%, respectively. The French version of the CPTS-RI demonstrated a three-factor structure. CONCLUSIONS: The CPTS-RI is reliable and valid in French-speaking children.

Prolonged and post-term pregnancies: guidelines for clinical practice from the French College of Gynecologists and Obstetricians (CNGOF).

The duration of pregnancy varies between 40(+0) and 41(+3) weeks. Conventionally, and essentially arbitrarily, a pregnancy is considered to be "prolonged" after 41(+0) weeks, but the infant is not considered "post-term" until 42(+0) weeks (Professional consensus). A term birth thus occurs during the period from 37(+0) to 41(+6) weeks. In France, prolonged pregnancies (≥41(+0)weeks) involve 15-20% of pregnant women, and post-term pregnancies (≥42(+0) weeks) approximately 1%. The frequency of post-term pregnancies is very heterogeneous: in Europe and the United States, it ranges from 0.5% to 10% according to country. In prolonged pregnancies, the cesarean section rate-especially the emergency cesarean rate-is multiplied by approximately 1.5 (grade B). From 37(0-6) to 43(0-6) weeks, the risk of perinatal mortality increases regularly, from 0.7‰ to 5.8‰. Meconium aspiration syndrome is responsible for substantial morbidity and mortality, and its incidence increases regularly between 38(+0) and 42(+6) weeks, from 0.24‰ to 1.42‰ (grade B). Similarly, the risks of neonatal acidosis (grade B), 5-min Apgar scores less than 7 (grade B) and admissions to neonatal intensive care (grade B) increase progressively between 38(+0) and 42(+6) weeks. These risks appear to double for post-term growth-restricted newborns (grade C). Ultrasound dating of the pregnancy makes it possible to reduce the risk that it will be incorrectly considered prolonged and that labor will therefore be induced unnecessarily. To harmonize practices, if the crown-rump length (CRL) is correctly measured (this measurement should be taken between 11(+0) and 13(+6) weeks, when CRL should measure from 45 to 84mm), ultrasound dating based on it should be used to determine the official date pregnancy began, regardless of its difference from the date assumed by the patient or estimated based on the date of the last menstrual period. This rule does not apply to pregnancies by IVF, for which the date pregnancy began is defined by the date of oocyte retrieval (Professional consensus). From 37(0-6) to 43(0-6) weeks, the risk of perinatal mortality increases regularly and there is no threshold at which a clear increase in perinatal mortality becomes visible. Fetal monitoring by cardiotocography (CTG) that begins at 41(+0) weeks would cover approximately 20% of women and reduce perinatal morbidity compared with monitoring that begins at 42(+0) weeks (grade C). The frequency recommended for this monitoring ranges between two and three times a week (Professional consensus). For ultrasonography assessment, measurement of the largest fluid pocket is recommended, because measurement of the amniotic fluid index (that is, the sum of the four quadrants) is accompanied by more diagnoses of oligohydramnios, inductions of labor, and cesareans for fetal distress without any improvement in neonatal prognosis (grade A). The practice of assessing the Manning biophysical score increases the number of diagnoses of oligohydramnios and fetal heart rage (FHR) abnormalities and generates an increase in the rates of inductions and cesareans without improving neonatal prognosis. The use of this biophysical score in monitoring prolonged pregnancies is therefore not recommended (grade B). In the absence of a specific disorder, induction of labor can be proposed in patients between 41(+0) and 42(+6) weeks (grade B). Nonetheless, the choice of prolongation beyond above 42(+0) weeks appears to involve an increase in fetal risk, which must be explained to the patient and balanced against the potential disadvantages of induction (Professional consensus). Stripping the membranes can reduce the duration of pregnancy by increasing the number of patients going into labor spontaneously during the week afterward (grade B). Compared to an expectant approach, it does not increase the cesarean section rate (grade A). It reduces recourse to induction by 41% at 41(+0) weeks and by 72% at 42(+0) weeks (grade B), without increasing the risk of either membrane rupture or maternal or neonatal infection (grade B). Used as a tampon or vaginal gel, prostaglandins E2 (PGE2) are an effective method of inducing labor (grade A). They can be used to induce labor successfully, regardless of cervical ripeness (grade A). If misoprostol is chosen, the lowest dose is to be preferred, starting with a vaginal dose of 25µg every 3-6h (grade A). For misoprostol, more powerful studies remain necessary for better defining the doses, routes of administration, tolerance and indications. Misoprostol at any dose is contraindicated in women with uterine scars (grade B). Placement of an intracervical Foley catheter is an effective mechanical means of inducing labor, with less uterine hyperstimulation than prostaglandins and no increase in the cesarean section rate (grade A). Nonetheless, as the risk of infection might be increased, this technique requires more robust evaluation before entering general practice (grade B). In cases of meconium-stained amniotic fluid, pharyngeal aspiration before delivery of the shoulders is not recommended (grade A). The team managing a post-term newborn with meconium-stained amniotic fluid at birth must know how to perform intubation and, if the intubation is not helpful, endotracheal aspiration (grade C) and ventilation with a mask. Routine endotracheal intubation of a vigorous newborn is not recommended (grade A).

Long-term use of standardised Ginkgo biloba extract for the prevention of Alzheimer's disease (GuidAge): a randomised placebo-controlled trial.

BACKGROUND: Prevention strategies are urgently needed to tackle the growing burden of Alzheimer's disease. We aimed to assess efficacy of long-term use of standardised ginkgo biloba extract for the reduction of incidence of Alzheimer's disease in elderly adults with memory complaints. METHODS: In the randomised, parallel-group, double-blind, placebo-controlled GuidAge clinical trial, we enrolled adults aged 70 years or older who spontaneously reported memory complaints to their primary-care physician in France. We randomly allocated participants in a 1:1 ratio according to a computer-generated sequence to a twice per day dose of 120 mg standardised ginkgo biloba extract (EGb761) or matched placebo. Participants and study investigators and personnel were masked to study group assignment. Participants were followed-up for 5 years by primary-care physicians and in expert memory centres. The primary outcome was conversion to probable Alzheimer's disease in participants who received at least one dose of study drug or placebo, compared by use of the log-rank test. This study is registered with ClinicalTrials.gov, number NCT00276510. FINDINGS: Between March, 2002, and November, 2004, we enrolled and randomly allocated 2854 participants, of whom 1406 received at least one dose of ginkgo biloba extract and 1414 received at least one dose of placebo. By 5 years, 61 participants in the ginkgo group had been diagnosed with probable Alzheimer's disease (1·2 cases per 100 person-years) compared with 73 participants in the placebo group (1·4 cases per 100 person-years; hazard ratio [HR] 0·84, 95% CI 0·60-1·18; p=0·306), but the risk was not proportional over time. Incidence of adverse events was much the same between groups. 76 participants in the ginkgo group died compared with 82 participants in the placebo group (0·94, 0·69-1·28; p=0·68). 65 participants in the ginkgo group had a stroke compared with 60 participants in the placebo group (risk ratio 1·12, 95% CI 0·77-1·63; p=0·57). Incidence of other haemorrhagic or cardiovascular events also did not differ between groups. INTERPRETATION: Long-term use of standardised ginkgo biloba extract in this trial did not reduce the risk of progression to Alzheimer's disease compared with placebo. FUNDING: Ipsen.

Concordance for curve type in familial idiopathic scoliosis: a survey of one hundred families.

STUDY DESIGN: Prospective comparative study on 100 patients with positive family history for idiopathic scoliosis. OBJECTIVE: To evaluate the concordance rate for curve pattern and side in family members with idiopathic scoliosis. SUMMARY OF BACKGROUND DATA: The pathogenesis of idiopathic scoliosis has been the subject of extensive research. It is termed multifactorial with a genetic component. Similar curve shape has been reported in twins with idiopathic scoliosis. METHODS: We included prospectively 100 patients with idiopathic scoliosis when a relative of them was also affected with idiopathic scoliosis, and spine radiographs were available for both. Concordance for curve pattern by Lenke classification and side between family members was analyzed. RESULTS: Familial concordance rate for curve pattern and side was 66% (95% confidence interval, 57-75), whereas the expected random concordance rate was 26% (95% confidence interval, 17-34). The affected relative was in 27 cases a sibling, in 32 cases a parent, in 1 case an uncle, in 2 cases a cousin, in 2 cases a half sister, in 2 cases a grandmother. Concordance rate was 65% (27/42) in siblings' pairs and 67% (32/48) in parents/child's pairs. CONCLUSION: We report a high concordance rate for curve pattern and side between relatives with idiopathic scoliosis. Curve shape is likely to be genetically determined in familial scoliosis. It seems important that curve type is documented and considered in future genetic studies.
