Abstract
Clinical genetic studies confirm the broader autism phenotype (BAP) in some relatives of individuals with autism, but there are few standardized assessment measures. We developed three BAP measures (informant interview, self-report interview, and impression of interviewee observational scale) and describe the development strategy and findings from the interviews. International Molecular Genetic Study of Autism Consortium data were collected from families containing at least two individuals with autism. Comparison of the informant and self-report interviews was restricted to samples in which the interviews were undertaken by different researchers from that site (251 UK informants, 119 from the Netherlands). Researchers produced vignettes that were rated blind by others. Retest reliability was assessed in 45 participants. Agreement between live scoring and vignette ratings was very high. Retest stability for the interviews was high. Factor analysis indicated a first factor comprising social-communication items and rigidity (but not other repetitive domain items), and a second factor comprised mainly of reading and spelling impairments. Whole scale Cronbach's alphas were high for both interviews. The correlation between interviews for factor 1 was moderate (adult items 0.50; childhood items 0.43); Kappa values for between-interview agreement on individual items were mainly low. The correlations between individual items and total score were moderate. The inclusion of several factor 2 items lowered the overall Cronbach's alpha for the total set. Both interview measures showed good reliability and substantial stability over time, but the findings were better for factor 1 than factor 2. We recommend factor 1 scores be used for characterising the BAP.

Abstract
A large number of studies have reported on the validity of autism spectrum disorder (ASD) screening procedures. An overall understanding of these studies' findings cannot be based solely on the level of internal validity of each, since screening instruments might perform differently according to certain factors in different settings. Europe has led the field with the development of the first screening tool and first prospective screening study of autism. This paper seeks to provide an overview of ASD screening studies and ongoing programmes across Europe, and identify variables that have influenced the outcomes of such studies. Results show that, to date, over 70,000 children have been screened in Europe using 18 different screening procedures. Differences among findings across studies have enabled us to identify ten factors that may influence screening results. Although it is impossible to draw firm conclusions as to which screening procedure is most effective, this analysis might facilitate the choice of a screening method that best fits a specific scenario, and this, in turn, may eventually improve early ASD detection procedures.

Abstract
While it is apparent that rare variation can play an important role in the genetic architecture of autism spectrum disorders (ASDs), the contribution of common variation to the risk of developing ASD is less clear. To produce a more comprehensive picture, we report Stage 2 of the Autism Genome Project genome-wide association study, adding 1301 ASD families and bringing the total to 2705 families analysed (Stages 1 and 2). In addition to evaluating the association of individual single nucleotide polymorphisms (SNPs), we also sought evidence that common variants, en masse, might affect the risk. Despite genotyping over a million SNPs covering the genome, no single SNP shows significant association with ASD or selected phenotypes at a genome-wide level. The SNP that achieves the smallest P-value from secondary analyses is rs1718101. It falls in CNTNAP2, a gene previously implicated in susceptibility for ASD. This SNP also shows modest association with age of word/phrase acquisition in ASD subjects, of interest because features of language development are also associated with other variation in CNTNAP2. In contrast, allele scores derived from the transmission of common alleles to Stage 1 cases significantly predict case status in the independent Stage 2 sample. Despite being significant, the variance explained by these allele scores was small (Vm< 1%). Based on results from individual SNPs and their en masse effect on risk, as inferred from the allele score results, it is reasonable to conclude that common variants affect the risk for ASD but their individual effects are modest.

Abstract
Autism spectrum disorder (ASD) is a highly heritable disorder of complex and heterogeneous aetiology. It is primarily characterized by altered cognitive ability including impaired language and communication skills and fundamental deficits in social reciprocity. Despite some notable successes in neuropsychiatric genetics, overall, the high heritability of ASD (~90%) remains poorly explained by common genetic risk variants. However, recent studies suggest that rare genomic variation, in particular copy number variation, may account for a significant proportion of the genetic basis of ASD. We present a large scale analysis to identify candidate genes which may contain low-frequency recessive variation contributing to ASD while taking into account the potential contribution of population differences to the genetic heterogeneity of ASD. Our strategy, homozygous haplotype (HH) mapping, aims to detect homozygous segments of identical haplotype structure that are shared at a higher frequency amongst ASD patients compared to parental controls. The analysis was performed on 1,402 Autism Genome Project trios genotyped for 1 million single nucleotide polymorphisms (SNPs). We identified 25 known and 1,218 novel ASD candidate genes in the discovery analysis including CADM2, ABHD14A, CHRFAM7A, GRIK2, GRM3, EPHA3, FGF10, KCND2, PDZK1, IMMP2L and FOXP2. Furthermore, 10 of the previously reported ASD genes and 300 of the novel candidates identified in the discovery analysis were replicated in an independent sample of 1,182 trios. Our results demonstrate that regions of HH are significantly enriched for previously reported ASD candidate genes and the observed association is independent of gene size (odds ratio 2.10). Our findings highlight the applicability of HH mapping in complex disorders such as ASD and offer an alternative approach to the analysis of genome-wide association data.

Abstract
Soaking in aqueous ammonia (SSA) and/or xylanase pretreatments were developed on wheat straw. Both pretreatments were conducted at high-solids conditions: 15% and 20%, respectively, for SSA and xylanase pretreatments. SSA pretreatment led to the solubilisation of 38%, 12% and 11% of acid insoluble lignin, xylan and glucan, respectively. In case of xylanase pretreatment, 20% of xylan were removed from native wheat straw. When pretreatments were applied consecutively (SSA and xylanase) on straw, 56% of xylans were hydrolysed and a rapid reduction of media viscosity occurred. The enzymatic hydrolysis of cellulose with cellulases was evaluated from the different combinations of pretreated wheat straw. Cellulose hydrolysis was improved by 2.1, 2.2 and 2.9, respectively, for xylanase, SSA and SSA/xylanase pretreated straw. Xylans from untreated and pretreated wheat straws were also solubilised with cellulases. Chemical analysis of pretreated straw residues in connection with yields of cellulose hydrolysis highlighted the role of phenolic acids, acetyl content and cellulose crystallinity for cellulase efficiency.

Abstract
Although autism spectrum disorders (ASDs) have a substantial genetic basis, most of the known genetic risk has been traced to rare variants, principally copy number variants (CNVs). To identify common risk variation, the Autism Genome Project (AGP) Consortium genotyped 1558 rigorously defined ASD families for 1 million single-nucleotide polymorphisms (SNPs) and analyzed these SNP genotypes for association with ASD. In one of four primary association analyses, the association signal for marker rs4141463, located within MACROD2, crossed the genome-wide association significance threshold of P < 5 × 10−8. When a smaller replication sample was analyzed, the risk allele at rs4141463 was again over-transmitted; yet, consistent with the winner's curse, its effect size in the replication sample was much smaller; and, for the combined samples, the association signal barely fell below the P < 5 × 10−8 threshold. Exploratory analyses of phenotypic subtypes yielded no significant associations after correction for multiple testing. They did, however, yield strong signals within several genes, KIAA0564, PLD5, POU6F2, ST8SIA2 and TAF1C.

Abstract
The autism spectrum disorders (ASDs) are a group of conditions characterized by impairments in reciprocal social interaction and communication, and the presence of restricted and repetitive behaviours. Individuals with an ASD vary greatly in cognitive development, which can range from above average to intellectual disability. Although ASDs are known to be highly heritable ( approximately 90%), the underlying genetic determinants are still largely unknown. Here we analysed the genome-wide characteristics of rare (<1% frequency) copy number variation in ASD using dense genotyping arrays. When comparing 996 ASD individuals of European ancestry to 1,287 matched controls, cases were found to carry a higher global burden of rare, genic copy number variants (CNVs) (1.19 fold, P = 0.012), especially so for loci previously implicated in either ASD and/or intellectual disability (1.69 fold, P = 3.4 x 10(-4)). Among the CNVs there were numerous de novo and inherited events, sometimes in combination in a given family, implicating many novel ASD genes such as SHANK2, SYNGAP1, DLGAP2 and the X-linked DDX53-PTCHD1 locus. We also discovered an enrichment of CNVs disrupting functional gene sets involved in cellular proliferation, projection and motility, and GTPase/Ras signalling. Our results reveal many new genetic and functional targets in ASD that may lead to final connected pathways.

Abstract
This study evaluated the clinical effectiveness of a programme aimed at detecting, preventing and treating postpartum depression. The French version of the EPDS was used to measure the intensity of postpartum blues on a sample of 859 women, during their stay at the obstetrical clinic. Subjects under treatment for psychological problems were excluded from the study. Mothers scoring 9 or above on the EPDS, which is predictive of pospartum depression, were randomly assigned to a prevention and a control group. Written informed consent was obtained from the subjects after the study procedure had been explained. The prevention group received a counselling session integrating supportive, educational and cognitive-behavioral components. Therapists included five female Master's Degree level students in psychology. All therapists participated in didactic and clinical training as wells as weekly supervision from the first author. All subjects were given a second EPDS with written instructions to complete the questionnaire during the period 4 to 6 weeks postpartum and return it for analysis. At four to 6 weeks, women in the prevention group had significant reductions in the frequency of probable depression, as defined by a score of 11 or above on the EPDS (30.2% vs 48.2%, chi 2 = 7.36, dl = 1, p = 0.0067) and in the intensity of depressive symptoms measured by the mean score on the EPDS (8.5, SD = 4 vs 10.3, SD = 4.4, t = 3.06, dl = 209, p = 0.0024). Mothers with a probable depression were interviewed at home and assessed using the MINI (Mini Neuropsychiatric Interview, Lecrubier et al., 1997) to diagnose major depressive episode, the SIGH-D (Structured Interview Guide for the Hamilton Depression Rating Scale, Williams, 1988) and the BDI (Beck Depression Inventory, Beck et al., 1988). The baseline depression rating scores, EPDS (mean = 13.6, SD = 4), BDI (mean = 15.7, SD = 5.9), HDRS (mean = 14.8, SD = 6), were consistent with moderate depression. No significant differences in baseline scores were observed between the two groups on all the rating scales (p < 0.001). Mothers with probable depression in the prevention group were offered a program of 5 to 8 home visits. Most of the mothers in the prevention group (72%) agreed to participate in the program. On the contrary, most of the mothers (83.3%) who scored below 9 on the first EPDS and 11 or above on the second, who so did not received the preventive counselling session, declined to participate. This suggests the importance of the preventive session in establishing therapeutic alliance. The home visits program integrated four components, supportive, educational, cognitive-behavioral and psychodynamic centred on the mother-infant relationship in terms of the mother's personal history. Therapist participated in clinical training and weekly supervision. Fifteen women (71.4%) in the study group demonstrated complete symptom remission, as defined by HDRS score below 7 after the intervention, compared with 4 women (10.5%) in the control group (chi 2 = 23, p < 0.0001). A clearly therapeutic response to treatment was observed in the treated group with a mean reduction in HDRS score of 9.5 (DS = 6.7) from baseline. The improvement in the women in the treated group, as measured by the mean HDRS scores was statistically greater than that in the control group (m = 5.35, SD = 3.5 vs m = 15.8, SD = 4.6, t = 8.24, dl = 52, p < 0.0001). Our results indicate that a program based on an intervention at obstetrical clinics and on home visits is efficacious and well accepted for prevention, detection and treatment of postpartum depression.

Abstract
OBJECTIVE To describe the use of second line protease-inhibitor (PI) regimens across Europe and to determine factors associated with virological and immunological response. DESIGN Analysis of data from 984 patients with a median follow-up of 21 months enrolled in EuroSIDA. Patients started their second PI-containing regimen at least 16 weeks after starting the first PI-containing regimen and with viral load > 1000 copies/ml. METHODS Virological response was defined as a viral load < 500 copies/ml and immunological response as an increase of 50 x 10(6)/l or more in CD4 lymphocyte count. RESULTS The median CD4 cell count at starting the second PI was 171 x 10(6) cells/l; viral load was 4.45 log copies/ml. As a second PI regimen, 45% were using a dual PI, while of those on one PI, indinavir (42%) and nelfinavir (34%) were most common. In multivariate Cox models, a higher viral load at starting the second PI [relative hazard (RH), 0.67 per 1 log higher; 95% confidence interval (CI), 0.58-0.77; P < 0.0001) and a lower CD4 cell count (RH, 1.15 per 50% higher; 95% CI, 1.06-1.26; P = 0.0014) were associated with a reduced probability of virological response. Those who had achieved viral suppression on the first PI-regimen were more likely to respond to the second (RH, 1.65; 95% CI, 1.30-2.10; P < 0.0001) as were those who added one or two new nucleosides to their second PI. CONCLUSIONS Patients who initiate a second PI regimen at lower viral load, higher CD4 cell count or who added new nucleosides tended to be more likely to achieve a viral load < 500 copies/ml. The roles of cross-resistance and adherence in response to second-line regimens needs further investigation.

Abstract
Results of recent studies in pharmacotherapy in autism are presented. Haloperidol, fenfluramine and naltrexone have been the most extensively studied drugs in systematic research. Haloperidol appeared to decrease levels of hyperactivity, stereotypies, emotional lability but also abnormal object relations and social withdrawal. However, the therapeutic effect was generally modest and long term administration was associated with dyskinesias in autistic children. The frequent hyperserotonemia in autism has suggested the use of fenfluramine, an antiserotoninergic agent. Although the initial reports were optimistic, more recent carefully designed studies often failed to show that fenfluramine was superior to placebo. Naltrexone, a potent opiate antagonist, was explored following the opioid hypothesis based on the similarity between autistic symptomatology and abnormal behaviors observed in opiate addicts and in laboratory animals administered opiates and on the abnormalities of endogenous opioids that exit in a subgroup of autistic children. However, the current studies do not concur and no definite conclusions can be made of the efficacy of naltrexone at present time. Low doses of amisulpride which have been shown to improve negative symptoms in schizophrenia and serotoninergic antidepressants, which have proven effective in repetitive and ritualized behaviors, have recently began to be evaluated in controlled studies. At present time, no medication has shown to alter the course or the symptoms of autism, but some seem to be effective in reducing severe aberrant behaviors.

Abstract
The surfaces of the epiphyses of the knees were calculated in 34 neonates with hypothyroidism detected with a systematic screening and in 32 normal neonates. In the group of neonates with hypothyroidism, the surface of the lower femoral point was 12.7 +/- 0.9 mm2 and that of the upper tibial point 1.8 +/- 0.9 mm2. There was a significant difference (P less than 0.01) for both epiphyses between children of the 2 groups. The use of mathematical formula excluding non specific factors showed significant correlation between the corrected values for lower femoral points, and T4 and T3 plasma levels. These corrected values were higher in neonates with thyroid ectopia than in neonates with thyroid aplasia. There was also a significant correlation between the corrected values for lower femoral points and the IQ at 6 months and 2 years. Thus, the calculation of the surface of the epiphyses of the knee may be considered as a criterion of duration and severity o hypothyroidism and may be an index for the determination of the ante- or post-natal onset of the disease.

Abstract
Thirty-five children in whom hypothyroidism was detected at birth were studied with respect to psychomotor development. A 5 year-follow-up was obtained in a few cases. The I.Q. was established using Brunet-Lezine's test or Griffith's test after age 30 months. Global quotients where normal: 98 + 10 at 6 months, 96 + 7 at 1 year, 99 + 7 at 3 years, 97 + 7 at 4 years and 97 + 4 at 5 years. Partial development quotients were normal concerning coordination and sociability. A transitory decrease was found at 1 year concerning posture and at 2 and 3 years concerning language, both returning to normal by age 4. These results were correlated with several factors: there was no significant difference between athyroidism and ectopia at the different ages but a difference appeared for partial development quotients at 2 and 3 years. There was no correlation between development quotients, clinical scores and dates of diagnosis. On the contrary, a significant correlation was found global development quotients at 6 months and the surfaces of epiphyses. Finally, a precise neurological evaluation showed an impairment of posture, coordination and fine movements of the extremities.

Abstract
Systematic screening for neonatal hypothyroidism has been undertaken since January 1977 in Southern France by the measurement of both T4 and TSH in dried blood eluates. 76,432 measurements were performed in 3 years and 22 cases of hypothyroidism were detected. There were several advantages of this method; detection of all forms of thyroid disease, immediate diagnosis of primary hypothyroidism with T4 < -2 S.D. and TSH > 80 microU/ml, decrease in the number of false positive results, detection of some false negative values with normal T4 but high TSH values. In Southern France the frequency of thyroid abnormalities is 1/34,000 births. The causes of these abnormalities in 22 cases was as follows: Absent thyroid (10), ectopic thyroid (11) and one thyroid in the normal position. In all cases TSH levels were above 80 microU/ml but in six cases with ectopic thyroids the T4 levels were between -1 and -2 S.D. These cases would not have been detected with T4 measurements alone.
