Our study on long-term outcome of presymptomatic testing for Huntington disease had two aims: the comparison of the psychological well-being and social adjustment of carriers and non-carriers of the ...mutation, and the identification of psychological determinants to improve care/support of testees. We performed a cross-sectional study of 351 persons who underwent presymptomatic testing. Those who had motor signs were excluded from the comparison of asymptomatic carrier and non-carriers. A structured interview including five self-report scales and the MINI (Mini International Neuropsychiatric Inventory) was proposed to detect a psychopathology or problem with social adjustment.We interviewed 119 testees (53%), 62 non-carriers and 57 carriers after a mean delay of 3.7 years (range: 0.32 to 8.9) after their result. Depression was frequent in asymptomatic carriers (58%). Interestingly, the self reported impact of the test showed that 27% of non-carriers did not cope well with a favourable result, and a significant percentage of non-carriers (24%) were depressed during follow-up. Multivariate analysis showed that only a previous episode of depression was predictive of depression after genetic testing in both carriers and non-carriers of the HD mutation (P<0.0001).Psychological support is necessary for all testees regardless of the result of their presymptomatic test, because psychiatric care is often needed by both carriers and non-carriers.
The objectives of this study were to obtain updated neonatal measurements in French newborns with Down Syndrome (DS) according to their gestational age, and to assess the frequency and distribution ...of congenital anomalies. Data on congenital malformations, birth weight, birth length and birth occipito‐frontal circumference (OFC) according to the gestational age was gathered from 1,030 babies, born between 1980 and 2010. The mean gestational age was 38 weeks from the date of the last menstrual period (LMP) (range: 29–42 weeks). Repartition of complications was found to be similar to previous studies, with no difference according to the date of birth. For girls born after 37 weeks, the mean birth weight was 3,012 ± 430 g, the mean birth length was 47.7 ± 2 cm, and the mean birth OFC was 33 ± 1.4 cm. For boys born after 37 weeks, the mean birth weight was 3,103 ± 459, the mean birth length was 48.4 ± 2.2 cm, and the mean birth OFC was 33.2 ± 1.4 cm. We did not find any difference in these measurements when we compared children born before 1997 and after 2007. When compared to the general population (French data and WHO charts), newborns with DS have a more pronounced difference in their birth length and their birth OFC (15–25th) than in their birth weight (25–50th). The shape of the growth curves shows that growth velocity decreases during the last weeks of gestation in all measurements, which suggests that the modal age for delivery could be earlier in DS newborns than in the general population.
Bi-allelic pathogenic variants in genes of the EIF2B family are responsible for Childhood Ataxia with Central nervous system Hypomyelination/Vanishing White Matter disease, a progressive ...neurodegenerative disorder of the central white matter. Only seven molecularly proven cases with antenatal onset have been reported so far. We report for the first time the neuropathological findings obtained from two foetuses harbouring deleterious variants in the EIF2B5 gene who presented in utero growth retardation and microcephaly with simplified gyral pattern that led to a medical termination of the pregnancy at 27 and 32 weeks of gestation. Neuropathological examination confirmed microcephaly with delayed gyration, periventricular pseudo-cysts and severe cerebellar hypoplasia. Histologically, the cerebellar cortex was immature, the dentate nuclei were fragmented and myelin stains revealed almost no myelination of the infratentorial structures. Bergmann glia was virtually absent associated to a drastic decreased number of mature astrocytes in the cerebellar white matter, multiple nestin-positive immature astrocytes as well as increased numbers of PDGRFα-positive oligodendrocyte precursors. Whole exome sequencing performed in the two foetuses and their parents allowed the identification of two EIF2B5 compound heterozygous variants in the two foetuses: c.468C > G p.Ile156Met and c.1165G > A p.Val389Met, the parents being heterozygous carriers. These variants are absent in the genome Aggregation Database (gnomAD r2.0.2). Contrary to the variant Ile156Met already described in a patient with CACH syndrome, the variant p.Val389Met is novel and predicted to be deleterious using several softwares. Neuropathological findings further expand the phenotypic spectrum of the disease that very likely occurs during early gestation and may manifest from the second half of pregnancy by a severe impairment of cerebral and cerebellar development.
No standard chemotherapy regimen exists for primary CNS lymphoma, reflecting an absence of randomised studies. We prospectively tested two promising methotrexate-based regimens, one more intensive ...and a milder regimen, for primary CNS lymphoma in the elderly population, who account for most patients.
In this open-label, randomised phase 2 trial, done in 13 French institutions, we enrolled immunocompetent patients who had neuroimaging and histologically confirmed newly diagnosed primary CNS lymphoma, were aged 60 years and older, and had a Karnofsky performance scale score of 40 or more. Participants were stratified by Karnofsky performance scale score (<60 vs ≥60) and treating institution and randomly assigned (1:1) to receive methotrexate (3·5 g/m(2)) with temozolomide (150 mg/m(2)) or methotrexate (3·5 g/m(2)), procarbazine (100 mg/m(2)), vincristine (1·4 mg/m(2)), and cytarabine (3 mg/m(2)). Neither regimen included radiotherapy; both included prophylactic G-CSF and corticosteroids. The primary endpoint was 1-year progression-free survival. Analysis was intent to treat, in a non-comparative phase 2 trial design. This study is registered with ClinicalTrials.gov, number NCT00503594.
Between July 16, 2007, and March 25, 2010, 98 patients were enrolled, of whom 95 were randomly assigned and analysed; 48 to methotrexate with temozolomide and 47 to methotrexate, procarbazine, vincristine, and cytarabine. 1-year progression-free survival was 36% (95% CI 22-50) in the methotrexate, procarbazine, vincristine, and cytarabine group and 36% (22-50) in the methotrexate with temozolomide group; median progression-free survival was 9·5 months (95% CI 5·3-13·8) versus 6·1 months (3·8-11·9), respectively. Objective responses were noted in 82% (95% CI 68-92) of patients in the methotrexate, procarbazine, vincristine, and cytarabine group versus 71% (55-84) of patients in the methotrexate with temozolomide group. Median overall survival was 31 months (95% CI 12·2-35·8) in the methotrexate, procarbazine, vincristine, and cytarabine group and 14 months (8·1-28·4) in the methotrexate with temozolomide group. No differences were noted in toxic effects between the two groups. The most common grades 3 and 4 toxicities in both groups were liver dysfunction (21 4% in the the methotrexate and temozolomide group and 18 38% in the methotrexate, procarbazine, vincristine, and cytarabine group), lymphopenia (14 29% and 14 30%), and infection (six 13% and seven 15%). To date, 33 (69%) patients in the methotrexate and temozolomide group have died, versus 31 (55%) in the methotrexate, procarbazine, vincristine and cytarabine group. Quality-of-life evaluation (QLQ-C30 and BN20) showed improvements in most domains (p=0·01-0·0001) compared with baseline in both groups. Prospective neuropsychological testing showed no evidence of late neurotoxicity.
In this study of two different methotrexate-based combination regimens in elderly patients, the efficacy endpoints tended to favour the methotrexate, procarbazine, vincristine, and cytarabine group. Both regimens were associated with similar, moderate toxicity, but quality of life improved with time, suggesting pursuing treatment in these poor prognosis patients is worthwhile. New alternatives are needed to improve response duration in this population.

Abstract This paper examined outcomes among youth with catatonic syndrome and determined whether the characteristics suggesting the relevance of chronic catatonic schizophrenia (CCS) at index episode ...remained stable at follow-up. From 1993 to 2004, 35 individuals aged 12 to 18 years were prospectively admitted for management of catatonic syndrome and followed up after discharge. Mean duration from discharge to follow-up was 3.9 years (range 1–10). Four patients were lost to follow-up. Among the remaining 31 subjects (mean age = 19.5 years, range 15–26), life-time diagnosis using the Diagnostic Interview for Genetic Studies was unchanged in 28 patients, and included schizophrenia (all subtypes; N = 20), major depressive episode ( N = 5), bipolar disorder type I ( N = 4) and brief psychotic episode ( N = 2). Mortality (all-cause Standardized Mortality Ratio = 6266; 95% CI = 1181–18,547) and morbidity were severe, with 3 deaths (including 2 suicides), 6 patients presenting with a causal organic condition and 14 subjects needing continuous psychiatric care. All males in the study ( N = 8) who had chronic catatonic schizophrenia at the index episode still had chronic catatonic signs at follow-up. Catatonia is one of the most severe psychiatric syndromes in adolescents. It is associated with a 60-fold increased risk of premature death, including suicide, when compared to the general population of same sex and age. This increased risk of premature death remains higher than the one measured in former adolescent psychiatric patients (all-cause SMR = 221; 95% CI = 156–303; Engqvist and Rydelius, 2006), or in schizophrenia irrespective to age and subtype (all-cause SMR = 157; 95% CI = 153–160; Harris and Barraclough, 1998).
Abstract
Circulating tumor cells (CTCs) and circulating tumor DNA (ctDNA) are two cancer-derived blood biomarkers that inform on patient prognosis and treatment efficacy in breast cancer. We ...prospectively evaluated the clinical validity of quantifying both CTCs (CellSearch) and ctDNA (targeted next-generation sequencing). Their combined value as prognostic and early monitoring markers was assessed in 198 HER2-negative metastatic breast cancer patients. All patients were included in the prospective multicenter UCBG study COMET (NCT01745757) and treated by first-line chemotherapy with weekly paclitaxel and bevacizumab. Blood samples were obtained at baseline and before the second cycle of chemotherapy. At baseline, CTCs and ctDNA were respectively detected in 72 and 74% of patients and were moderately correlated (Kendall’s
τ
= 0.3). Only 26 (13%) patients had neither detectable ctDNA nor CTCs. Variants were most frequently observed in
TP53
and
PIK3CA
genes
. KMT2C

MLL3
variants detected in ctDNA were significantly associated with a lower CTC count, while the opposite trend was seen with
GATA3
alterations. Both CTC and ctDNA levels at baseline and after four weeks of treatment were correlated with survival. For progression-free and overall survival, the best multivariate prognostic model included tumor subtype (triple negative vs other), grade (grade 3 vs other), ctDNA variant allele frequency (VAF) at baseline (per 10% increase), and CTC count at four weeks (≥5CTC/7.5 mL). Overall, this study demonstrates that CTCs and ctDNA have nonoverlapping detection profiles and complementary prognostic values in metastatic breast cancer patients. A comprehensive liquid-biopsy approach may involve simultaneous detection of ctDNA and CTCs.
Context:
Cyclophosphamide is used for renal and major extrarenal involvement in systemic lupus erythematosus (SLE) and is associated with a risk of premature ovarian failure. There are no data ...available about the relation between anti-Müllerian hormone (AMH) serum levels and the probability of subsequent pregnancy in SLE patients.
Objective:
We analyzed AMH levels and the probability of pregnancy in SLE women exposed to cyclophosphamide.
Design and Setting:
We conducted a matched cohort study in referral centers for SLE.
Patients:
Fifty-six cyclophosphamide-exposed SLE women younger than 40 years of age and 56 control SLE women matched for age within 6 months participated in the study.
Main Outcome Measures:
AMH was measured in samples from the PLUS study (ClinicalTrials.gov no. NCT00413361). All patients were interviewed in May 2012 regarding their obstetric status.
Results:
The mean age ± SD of the 112 patients was 31.6 ± 5.8 years. The mean AMH level was low (1.21 ± 1.01 ng/mL) and was significantly lower in patients exposed to cyclophosphamide (P = .03) and in patients older than 30 years (P = .02). During a median follow-up (interval between sampling and the interview) period of 4.2 (range, 2.5–4.8) years, 38 patients sought to become pregnant, and 32 (84.2%) succeeded. In the univariate analysis, the risk of failure was associated with cumulative cyclophosphamide dose (P = .007) and older age (P = .02), but not with AMH.
Conclusion:
We confirmed that AMH levels are low in SLE patients and decrease significantly with age and cyclophosphamide exposure. Nonetheless, the risk of failure to conceive was low and was predicted by cyclophosphamide exposure and age, but not by AMH levels.
Clopidogrel loading has mostly been studied in clopidogrel-naïve patients. Whether clopidogrel-treated patients readmitted for an acute coronary syndrome or percutaneous coronary intervention can ...benefit from a new load of clopidogrel and at what dose remain unknown. Our aim was to evaluate the impact of 3 different strategies of administration of a loading dose of 900 mg clopidogrel in patients already treated with a maintenance dose of 75 mg clopidogrel for at least 7 days on residual platelet aggregation.
Patients treated long term by clopidogrel 75 mg/d were assigned to receive a first loading dose of 300, 600, or 900 mg clopidogrel and 4 hours later a second loading dose of 600, 300, or 0 mg, respectively, to achieve a total loading dose of 900 mg in all patients. Platelet aggregation was evaluated at baseline, at 4 hours after the initial load (and before second load), and at 24 hours using light transmission aggregometry with 20 micromol ADP and the point-of-care assay VerifyNow P2Y(12). The primary objective of the study was to evaluate the inhibition (relative change) of residual platelet aggregation (percentage of IRPA) between 600- and 900-mg first loading at 4 hours. IRPA at 24 hours also was evaluated as a secondary objective, as well as the rate of suboptimal response at 4 hours defined as IRPA <10%. We included 166 consecutive patients with acute coronary syndromes (n=80, 48%) or stable coronary artery disease (n=86, 52%). Baseline characteristics were similar in the 3 dose groups. A significant stepwise increase was found in percentage IRPA assessed at 4 hours in patients initially assigned to 300 versus 600 versus 900 mg (30.7% versus 40.3% versus 64.0%, respectively; P=0.0024). The difference in percentage IRPA at 4 hours was not significant between 300 and 600 mg but was significant between 600 and 900 mg and between 300 and 900 mg. Percentage IRPA assessed at 24 hours when all patients had received 900 mg did not differ between the 3 loading regimens. The rates of suboptimal response (IRPA <10% at 4 hours) were 23.6%, 20.4%, and 5.3% with 300, 600, and 900 mg, respectively (P=0.02 for all).
In patients treated long term with 75 mg clopidogrel, a new loading dose of 900 mg improves IRPA and reduces poor and/or slow response to clopidogrel significantly more than that obtained with 300 or 600 mg.
Polyhandicap (PLH) is a condition of severe and complex disabilities and is defined by a combination of profound intellectual impairment and serious motor deficits. Parents of PLH individuals are ...chronically confronted with stressful situations. The aims of this study are i) to assess and compare the quality of life (QoL) of a large panel of parents of PLH individuals with age- and gender-matched controls and ii) to identify potential determinants of parents' QoL.
We conducted a cross-sectional study. Parents were recruited from 4 specialized rehabilitation centres, 9 residential facilities, and a specialized paediatric/neurological department. The selection criteria were age above 18 years and being the mother/father of a PLH individual. The data collected from the parents included sociodemographic, health status, and psycho-behavioural data (including QoL); additionally, the health status of the PLH individuals was collected.
The QoL scores of all dimensions were significantly lower for parents than for controls. The main factors modulating parents' QoL were financial issues, health status, and coping strategies. The PLH individuals' health status was not associated with parents' QoL.
Some QoL determinants might be amenable. These findings should help health care workers and health decision makers to implement specific and appropriate interventions.
