RESUMO

BACKGROUND: Few data are available on long-term fatigue (LTF) and quality of life (QoL) among epithelial ovarian cancer survivors (EOCS). In this case-control study, we compared LTF, symptoms and several QoL domains in EOCS relapse-free ≥3 years after first-line treatment and age-matched healthy women. PATIENTS AND METHODS: EOCS were recruited from 25 cooperative GINECO centers in France. Controls were randomly selected from the electoral rolls. All participants completed validated self-reported questionnaires: fatigue (FACIT-F), QoL (FACT-G/O), neurotoxicity (FACT-Ntx), anxiety/depression (HADS), sleep disturbance (ISI), and physical activity (IPAQ). Severe LTF (SLTF) was defined as a FACIT-F score <37/52. Univariate and multivariate logistic regressions were conducted to analyze SLTF and its influencing factors in EOCS. RESULTS: A total of 318 EOCS and 318 controls were included. EOCS were 63-year-old on average, with FIGO stage I/II (50%), III/IV (48%); 99% had received platinum and taxane chemotherapy, with an average 6-year follow-up. There were no differences between the two groups in socio-demographic characteristics and global QoL. EOCS had poorer FACIT-F scores (40 versus 45, P < 0.0001), lower functional well-being scores (18 versus 20, P = 0.0002), poorer FACT-O scores (31 versus 34 P < 0.0001), and poorer FACT-Ntx scores (35 versus 39, P < 0.0001). They also reported more SLTF (26% versus 13%, P = 0.0004), poorer sleep quality (63% versus 47%, P = 0.0003), and more depression (22% versus 13%, P = 0.01). Fewer than 20% of EOCS and controls exercised regularly. In multivariate analyses, EOCS with high levels of depression, neurotoxicity, and sleep disturbance had an increased risk of developing SLTF (P < 0.01). CONCLUSION: Compared with controls, EOCS presented similar QoL but persistent LTF, EOC-related symptoms, neurotoxicity, depression, and sleep disturbance. Depression, neuropathy, and sleep disturbance are the main conditions associated with severe LTF.

RESUMO

BACKGROUND: Fludarabine/busulfan-based conditioning regimens are widely used to perform allogeneic stem-cell transplantation (allo-SCT) in high-risk non-Hodgkin lymphoma (NHL) patients. The impact of the dose intensity of busulfan on outcomes has not been reported yet. PATIENTS AND METHODS: This was a retrospective with the aim to compare the outcomes of NHL patients who received before allo-SCT a fludarabine/busulfan conditioning regimen, either of reduced intensity (FB2, 2 days of busulfan at 4 mg/kg/day oral or 3.2 mg/kg/day i.v.) (n = 277) or at a myeloablative reduced-toxicity dose (FB3/FB4, 3 or 4 days of busulfan at 4 mg/kg/day oral or 3.2 mg/kg/day i.v.) (n = 101). RESULTS: In univariate analysis, the 2-year overall survival (FB2 66.5% versus 60.3%, P = 0.33), lymphoma-free survival (FB2 57.9% versus 49.8%, P = 0.26), and non-relapse mortality (FB2 19% versus 21.1%, P = 0.91) were similar between both groups. Cumulative incidence of grade III-IV acute graft versus host disease (GVHD) (FB2 11.2% versus 18%, P = 0.08), extensive chronic GVHD (FB2: 17.3% versus 10.7%, P = 0.18) and 2-year GVHD free-relapse free survival (FB2: 44.4% versus 42.8%, P = 0.38) were also comparable. In multivariate analysis there was a trend for a worse outcome using FB3/FB4 regimens (overall survival: HR 1.47, 95% CI: 0.96-2.24, P = 0.08; lymphoma-free survival: HR: 1.43, 95% CI: 0.99-2.06, P = 0.05; relapse incidence: HR 1.54; 95% CI: 0.96-2.48, P = 0.07). These results were confirmed using a propensity score-matching strategy. CONCLUSION: We conclude that reduced toxicity myeloablative conditioning with fludarabine/busulfan does not improve the outcomes compared with reduced-intensity conditioning in adults receiving allo-SCT for NHL.

RESUMO

Electroencephalography allows the functional analysis of electrical brain cortical activity and is the gold standard for analyzing electrophysiological processes involved in epilepsy but also in several other dysfunctions of the central nervous system. Morphological imaging yields complementary data, yet it cannot replace the essential functional analysis tool that is EEG. Furthermore, EEG has the great advantage of being non-invasive, easy to perform and allows control tests when follow-up is necessary, even at the patient's bedside. Faced with the advances in knowledge, techniques and indications, the Société de Neurophysiologie Clinique de Langue Française (SNCLF) and the Ligue Française Contre l'Épilepsie (LFCE) found it necessary to provide an update on EEG recommendations. This article will review the methodology applied to this work, refine the various topics detailed in the following chapters. It will go over the summary of recommendations for each of these chapters and underline proposals for writing an EEG report. Some questions could not be answered by the review of the literature; in those cases, an expert advice was given by the working and reading groups in addition to the guidelines.

RESUMO

A biologically inspired navigation system for the mobile rat-like robot named Psikharpax is presented, allowing for self-localization and autonomous navigation in an initially unknown environment. The ability of parts of the model (e.g. the strategy selection mechanism) to reproduce rat behavioral data in various maze tasks has been validated before in simulations. But the capacity of the model to work on a real robot platform had not been tested. This paper presents our work on the implementation on the Psikharpax robot of two independent navigation strategies (a place-based planning strategy and a cue-guided taxon strategy) and a strategy selection meta-controller. We show how our robot can memorize which was the optimal strategy in each situation, by means of a reinforcement learning algorithm. Moreover, a context detector enables the controller to quickly adapt to changes in the environment-recognized as new contexts-and to restore previously acquired strategy preferences when a previously experienced context is recognized. This produces adaptivity closer to rat behavioral performance and constitutes a computational proposition of the role of the rat prefrontal cortex in strategy shifting. Moreover, such a brain-inspired meta-controller may provide an advancement for learning architectures in robotics.

RESUMO

BACKGROUND: The Loire Infant Follow-up Team (LIFT) is a network for caring for premature infants whose gestational age is 34 WA or less and at-risk neonates in the Pays-de-la-Loire area in France. The network aims to screen for clinical anomalies early and to propose adapted care. Trained physicians follow the included children in a standardized manner at 3, 6, 9, 12, and 18 months and 2 years, with a specific examination by psychologists at 2 years. The aim of the study was to assess the satisfaction of the parents of the children followed. METHODS: To evaluate parent satisfaction, a questionnaire from the Consumer Satisfaction Survey (CSS) in its French version was sent to parents whose infants were 2 years old, stratifying on the presence of an anomaly. The questioner had 39 items, with 8 specific items on the network and 31 from the CSS. The questionnaire was mailed twice in September 2006. RESULTS: Out of 300 questionnaires mailed, 269 were returned (rate 89.7 %). The questionnaire was assessed using principal component analysis with 2 dimensions for the 30 items common to all children, one of which covered empathy with physicians and the other with the consulting psychologists at 2 years. The validity was good (Cronbach coefficient, 0.91). The answers to overall questions such as "We are satisfied with the care in the network" scored 16.1±0.7/20, with 90 % "totally agree" or "moderately agree" responses. The "The care is perfect" scored 14.6±0.7/20 with 78 % agreeing with the statement. The total score for 30 general questions was 14.6±3.1 (median, 14.9). The total score was lower for infants with anomalies: 13.7±3.3 versus 14.9±2.9 (P<0.01). The answers with a low score (<10) were given by 22 parents (8.2 %). There was no significant relation between the total score or the satisfaction score and neonatal events. CONCLUSION: A postal survey is helpful to know the views of parents on the follow-up of their infants. This good level of satisfaction seems to stem from the parents feeling they belong to the network, the quality of the relationships with personnel, and the doctors' empathy, as well as the number of contacts between parents and the network coordinator.

RESUMO

AIM: To estimate the re-hospitalization rate of extremely preterm children during infancy and associated factors after the recent improvement in survival rates. METHOD: The cohort included all children born before 29 wk of gestation in nine French regions in 1997. All admissions between discharge from initial hospitalization and 9 mo after birth were considered. Factors studied included the child's characteristics at birth and during neonatal hospitalization, risk factors for infection after discharge and parents' socio-demographic characteristics. Adjusted odds ratios (aOR) for re-hospitalization for all reasons and for respiratory disorders were obtained from logistic regression models. RESULTS: Of the 376 children, 178 were re-admitted at least once (47.3%; 95% CI: 42.3-52.4). Fifty-five percent of the hospitalized children were admitted at least once for respiratory disorders. The re-hospitalization rate was higher for children who had had chronic lung disease (aOR: 2.2; 95% CI: 1.3-3.7), those initially discharged between August and October (aOR: 2.5; 95% CI: 1.2-5.1) or between November and January (aOR: 3.2; 95% CI: 1.5-6.8), and children living with other children under six (aOR: 3.4; 95 %CI: 1.6-7.5). Re-hospitalizations were associated with neither gestational age nor the duration of neonatal hospitalization. Adjusted odds ratios for re-hospitalization for respiratory tract disorders were very similar to those for the overall hospitalizations. CONCLUSION: Infants born before 29 wk have a very high risk of re-hospitalization. The associated factors can help define high-risk groups at discharge from the neonatal unit who need special surveillance.

RESUMO

Newborns are given attentive perinatal care but the organization of further follow-up can be haphazard. The main consequences are the difficulties parents have in finding appropriate medical assistance for caring for high-risk infants and the absence of appropriate surveillance or efficient care. An inpatient-outpatient healthcare network enables early care of these infants and can reduce the consequences of neurosensorial sequelae. The overall impact of the regional perinatal care can also be evaluated. Such a network has been implemented in the Pays de Loire region in France since early 2003. In six months, among 1000 initially included infants, 500 were followed by pediatricians working in an outpatient (40%) or inpatient (60%) setting. This organization enables correction of over-centralization of neonatal care and the absence of coordination for follow up.

RESUMO

PURPOSE: To report three cases of infantile spasms (IS) with an abnormal magnetic resonance imaging signal in the basal ganglia (Leigh-like syndrome), due to T8993G mt DNA mutation. PATIENTS AND RESULTS: The first sign was, at the end of the first year of life, IS in one case and the combination of IS with behavior changes in the two other cases. Video EEG polygraphy demonstrated both spasms and hypsarrhythmia, but no other kind of seizures. Vigabatrin or steroids controlled the spasms with a follow-up of several years. All 3 patients had hyperlactatorrhachia (3.47 to 7 mmol/l). Axial hypotonia and dystonia appeared by the end of the first year of life. As in cases with the NARP mutation and onset later in life, neuropathy and retinopathy could also be demonstrated. DISCUSSION: Although it is well established that symptomatic IS with hypsarrhythmia mainly result from cortical lesions, this epileptic encephalopathy may also be generated by lesions in the basal ganglia without evidence of cortical damage. This finding suggests that West syndrome is likely to be caused by age-related dysfunction at any level of a cortico-putaminal loop of hyperexcitability.

RESUMO

Heterozygous, de novo mutations in the glial fibrillary acidic protein (GFAP) gene have recently been reported in 12 patients affected by neuropathologically proved Alexander disease. We searched for GFAP mutations in a series of patients who had heterogeneous clinical symptoms but were candidates for Alexander disease on the basis of suggestive neuroimaging abnormalities. Missense, heterozygous, de novo GFAP mutations were found in exons 1 or 4 for 14 of the 15 patients analyzed, including patients without macrocephaly. Nine patients carried arginine mutations (four had R79H; four had R239C; and one had R239H) that have been described elsewhere, whereas the other five had one of four novel mutations, of which two affect arginine (2R88C and 1R88S) and two affect nonarginine residues (1L76F and 1N77Y). All mutations were located in the rod domain of GFAP, and there is a correlation between clinical severity and the affected amino acid. These results confirm that GFAP mutations are a reliable molecular marker for the diagnosis of infantile Alexander disease, and they also form a basis for the recommendation of GFAP analysis for prenatal diagnosis to detect potential cases of germinal mosaicism.
