Abstract
INTRODUCTION Announcing the diagnosis allows the therapeutic alliance between physicians and patients to be sealed and it prevents abandonment of treatment. To compensate for the deficit in information received by the families, the Franco-African Group of Pediatric Oncology (FAGPO) has published an "African Pediatric Cancer Announcement Guide" for the group's pediatric oncology units. OBJECTIVE To analyze the announcements made to parents and children 2 years after the provision of this guide. METHODS Cross-sectional survey conducted from March to July 2016. In total, 69 parents of children followed up in the pediatric oncology unit of Abidjan were interviewed regarding the characteristics of the announcement that was made to them and the information given to the sick child. RESULTS Of all the accompanying individuals, 91% reported having benefited from the announcement made with empathy, mainly by a physician. In approximately one quarter of the cases the information had been given to a third party. The main barriers to information were: the negative experiences of parents, the medical terminology, and communication problems. The sick child was rarely informed. DISCUSSION The information given was in accordance, in content and form, with the data from Western and African literature. The lack of information given to the child has a dual explanation: the primacy of the community over the individual advocated by African culture and the non-integration of the rights of children in the current code of ethics. CONCLUSION The information provided could be improved by practical training of physicians in the technique of breaking bad news to patients and their families and the use of a code of ethics in accordance with the principle of autonomy.

Abstract
Exercise and health psychology have generated 2 sets of empirical studies guided by separate theory-driven axes. The first axis focuses on the causal relationship between chronic exercise and cognition and, more particularly, high-level cognitive functions such as executive functions (EFs). The second axis examines factors influencing the adherence process to physical activity (PA). Research conducted during the past decade shows that these 2 topics are closely linked, with EFs and effortful control playing a pivotal role in the bidirectional relationship linking PA and mental/brain health. The present article supports the idea that an individual engaged in the regular practice of effortful PA initiates a virtuous circle linking PA and effortful control in a bidirectional way. On the one hand, chronic exercise leads to an improvement of EFs and effortful control. On the other hand, gains in EFs and effortful control effectiveness lead to a reciprocal facilitation of the maintenance of PA over time. Some limitations and perspectives to this effort hypothesis are proposed in the last part of the article.

Abstract
OBJECTIVE Emilin-1 is a versatile protein abundant in tissues where resilience and elastic recoil are prominent and interacting with components of the extracellular matrix. Still, little is known about Emilin-1 in the skin. Therefore, we investigated Emilin-1 in the skin, its localization, its fate upon ageing, its interactions with other proteins and the effect of its knockdown. METHODS Skin explants from young or old Caucasian women, immunofluorescently labelled by anti-Emilin-1, anti-Fibrillin-1 and anti-Elastin antibodies, were analysed using confocal microscopy. Skin explants subjected to UV-induced skin ageing were also analysed. Colocalization of Emilin-1 with Collagen IV, Fibrillin-1 and Elastin was studied by multiphoton microscopy and co-immunoprecipitation. Finally, the effect of Emilin-1 extinction was studied by producing small interfering RNA (siRNA) knockdown fibroblasts and by analysing the outcome on selected genes. RESULTS In skin sections from young donors, Emilin-1 localizes similarly to Elastin and Fibrillin-1. In the papillary dermis, it shows clear and ramified structures, perpendicular to the dermo-epidermal junction that are reminiscent of the oxytalan fibres. In the reticular dermis, Emilin-1 signal appears identical to that of the elastic fibres network. Upon intrinsic or UV-induced ageing, the signal associated with Emilin-1 is drastically reduced and disorganized. Multiphoton microscopy study shows that, as expected, Emilin-1 colocalizes with Elastin. It also colocalizes with Collagen IV in the basement membrane and within dermal fibroblasts. Interaction of Emilin-1 with Elastin and Collagen IV was also found by co-immunoprecipitation. It also reveals interaction with Laminin-5. Finally, siRNA-mediated knockdown of EMILIN-1 show little effect on the expression level of the 61 genes we studied. The most striking change is a downregulation of fibroblast growth factor receptor 2 that show a decrease similar to that of EMILIN-1 itself and after 8 days a downregulation of COL6A1. CONCLUSION In skin, Emilin-1 locates in the dermis, up to the basement membrane, interacting with components of the extracellular matrix but also with the anchoring complex. These interactions are important for cell adhesion, migration, proliferation and would suggest that Emilin-1 might be important for maintaining the 3D structure of the extracellular matrix.

Abstract
BACKGROUND Although the complications of Zika virus infection have been well described, the clinical pattern has not been reported in enough detail to differentiate this infection from those with other arboviroses, and no longitudinal study has yet been published on the persistence of symptoms and quality of life. OBJECTIVES were to describe bio-clinical pattern and quality of life during ZIKV infection, and their evolution. STUDY DESIGN We present a 1-year clinical follow-up of 49 people infected with Zika virus in French Guiana, for whom the diagnosis was confirmed by RT-PCR in serum or urine. RESULTS Fever was inconsistent (95% confidence interval (CI), 39-67). Exanthema (CI, 84-100) was maculopapular, with pruritus and conjunctivitis, variable over time and disappeared 12 days after the onset of symptoms (CI, 10-14). Joint pain (CI, 39-67) occurred mainly in the hands, wrists, knees and ankles and lasted for 10 days (CI, 7-13). Asthenia (CI, 61-85) scored low (3/10) but lasted for 19 days (CI, 16-22). The last two symptoms strongly limited patients' activities in the acute stage of the disease (RAPID-3 score, CI, 5-8). None of the patients had neurological complications, but 41% (CI, 27-55) had areflexia during the first month. CONCLUSIONS We found no real chronic evolution or decreased quality of life, function or ability to work from the first month after symptom onset.

Abstract
Background: In the elderly, physical activity (PA) enhances cognitive performances, increases brain plasticity and improves brain health. The neurotrophic hypothesis is that the release of brain-derived neurotrophic factor (BDNF), which is implicated in brain plasticity and cognition, is triggered by PA because motoneurons secrete BDNF into the bloodstream during exercise. Individual differences in cognitive performance may be explained by individual differences in genetic predisposition. A single nucleotide polymorphism on the BDNF gene, BDNFVal66Met, affects activity-dependent BDNF secretion. This study investigated the influence of the BDNFVal66Met polymorphism on the relationship between PA and controlled inhibition performance in older adults. Methods: A total of 114 healthy elderly volunteers (mean age = 71.53 years old) were evaluated. Participants were genotyped for the BDNFVal66Met polymorphism. We evaluated inhibitory performance using choice reaction times (RT) and error rates from a Simon-like task and estimated their PA using two self-reported questionnaires. We established four groups according to PA level (active vs. inactive) and BDNFVal66Met genotype (Met carriers vs. Val-homozygous). The results were analyzed using ANOVA and ANCOVA, including age, gender and body mass index as covariates. Results: The BDNFVal66Met polymorphism interacted with PA on controlled inhibition performance. More specifically, inactive Val-homozygous participants exhibited a lower inhibition performance than active Val homozygotes and inactive Met carriers; the former had a higher error rate without differences in RT. Conclusion: Differences between individuals on inhibitory performance may be partially understood by the interaction between genetic influence in BDNF secretion and PA level. The results of this study clearly support the neurotrophic hypothesis that BDNF synthesis is an important mechanism underlying the influence of physical activity on brain structure and functions.

Abstract
The aim of the present study was to provide descriptive dietary patterns of home-living older adults, and to examine their association with sociodemographic and 'diet-related' variables, and health and psychological factors. Dietary patterns were analyzed using separately cluster analysis for men (N=151,Mage=72.72, SD=8.80, range=56-97) and women (N=251, Mage=76.74, SD=9.95, range=55-97) in 402 older adults aged 55 years and over. Cluster analyses showed four distinct dietary profiles for each gender. In older men, the four distinct dietary clusters were associated with any differences in sociodemographic and 'diet-related' variables, cognitive function, and health and psychological factors. Likewise, in older women, the four distinct dietary clusters were associated with any differences in sociodemographic and 'diet-related' variables'. However in older women, results showed that the cluster 1 "high fish-fruit-vegetable" was associated with a better cognitive function, a better self-rated health and no depressive symptoms, whereas cluster 3 "moderate ready meals" was associated with cognitive decline, slight depression, and poor perceived health. Results emphasize the interest to take into consideration health and psychological factors associated with dietary patterns to better target the vulnerability of individuals and enable an effective prevention.

Abstract
It is well-known that processing speed and executive functions decline with advancing age. However, physical activity (PA) has a positive impact on cognitive performances in aging, specifically for inhibition. Less is known concerning intraindividual variability (iiV) in reaction times. This study aims to investigate the influence of PA and sex differences on iiV in inhibitory performance during aging. Healthy adults were divided into active and sedentary groups according to PA level. To analyse iiV in reaction times, individual mean, standard deviation and the ex-Gaussian parameters were considered. An interaction between activity level and sex was revealed, sedentary females being slower and more variable than sedentary men. No sex differences were found in the active groups. These results indicate that the negative impact of sedentariness on cognitive performance in older age is stronger for females. The present findings underline the need to consider sex differences in active aging approaches.

Abstract
In this paper, we investigate the recovery of some semiconductor-based components, such as N/P-type field-effect transistors (FETs) and a complementary metal-oxide-semiconductor (CMOS) inverter, after being exposed to a high total dose of gamma ray radiation. The employed method consists mainly of a rapid, low power and in situ annealing mitigation technique by silicon-on-insulator micro-hotplates. Due to the ionizing effect of the gamma irradiation, the threshold voltages showed an average shift of -580 mV for N-channel transistors, and -360 mV for P-MOSFETs. A 4 min double-cycle annealing of components with a heater temperature up to 465 °C, corresponding to a maximum power of 38 mW, ensured partial recovery but was not sufficient for full recovery. The degradation was completely recovered after the use of a built-in high temperature annealing process, up to 975 °C for 8 min corresponding to a maximum power of 112 mW, which restored the normal operating characteristics for all devices after their irradiation.

Abstract
The aims of this study were to examine the effects of aerobic exercise on measures of executive performance and their relationships with changes in cardiorespiratory fitness, cardiac vagal control (heart rate variability) and psychological variables. Thirty-six sedentary seniors aged 60-75 years were randomly assigned to a swimming and aquaerobics program or a stretching program two times a week for 21 weeks. Executive functions (inhibition, updating of working memory and cognitive flexibility) and cardiorespiratory fitness (estimated VO2max) were assessed at the start, after 10 weeks of program and at the end of the program. Resting HRV and measures of psychological outcomes (depression, self-efficacy, decisional balance) were obtained at the start and at the end of the program. Participants of both groups significantly improved their VO2max level, their psychological state and their performance for the 2-back task. Only the participants in the aquaerobics group significantly improved their vagally-mediated HRV and their performance for the Stroop test and the verbal running-span test at the end of the program. Only improvements in cardiac vagal control and in inhibition were shown to be functionally related. These results are discussed in line with the model of neurovisceral integration.

Abstract
BACKGROUND Metronomics is defined by the combination of metronomic chemotherapy and drug repositioning. Since off-patent chemotherapeutic drugs can be used and given the low toxicity profile of this approach, metronomics appears to be an invaluable alternative to bring affordable targeted therapies in low-income countries. OBJECTIVE The aim of this study was to report on the preliminary efficacy and safety of a metronomic vincristine/cyclophosphamide/methotrexate/valproic acid regimen given to children with refractory cancer of various tumor types or with a very advanced disease. MATERIALS AND METHODS This prospective, single-center study evaluated the use of a metronomics protocol, consisting of a first cycle of weekly vincristine 1.5 mg/m2 (days: 1, 8, 15 and 22), daily cyclophosphamide 25 mg/m2 (days: 1-21), twice weekly methotrexate 15 mg/m² (days: 21-42) and daily valproic acid (30 mg/kg/d) followed by a 1-week break. For the following cycles, vincristine was administrated only at week 1 and 5 of the cycle. This treatment was proposed to children with refractory disease and patients who were not eligible for the protocols available in the hospital. Adverse events were determined through laboratory analyses and investigator observations. RESULTS From January 2010 to January 2011, 7 children (mean age: 5.4 ± 3 years old) were treated. Most frequent diagnosis was retinoblastoma. Two partial responses were observed in patients with neuroblastoma and retinoblastoma. These two patients are alive with stable disease at last follow-up (6 and 26 months, respectively) after stopping treatment. CONCLUSION Metronomics allows treating patients with advanced or refractory or relapsing disease and the introduction of targeted treatments in low-income countries. The potential of metronomics in children and young adults living in middle- and low-income countries warrants further larger studies.

Abstract
BACKGROUND The outcome of children with refractory/relapsed malignancies remains poor and novel therapies are urgently required. One of the promising approaches is metronomic chemotherapy. We present the clinical results of 74 children with advanced solid tumors treated according to treatment recommendation with data registry in three European pediatric centers. METHODS COMBAT (Combined Oral Metronomic Biodifferentiating Antiangiogenic Treatment) included low-dose daily temozolomide, etoposide, celecoxib, vitamin D, fenofibrate and retinoic acid. From 2004 to 2010, 74 children were enrolled. RESULTS The 2-year overall survival (OS) was 43.1% (median 15.4, range 1.3-69.9 months). Of the 74 patients, 50 patients (68%) died and 24 are alive: 6 (8%) with progressive disease, 7 (9%) with stable disease/partial response and 11 (15%) in complete response. Median time to response was 6 months. Of 62 patients with initially measurable disease, 25 (40%) had radiological response or stable disease. Fourteen of 25 showing clinical benefit responded within the first 6 months. The treatment was well tolerated on an outpatient basis. Regarding non-hematological toxicity of grade ≥2, hepatotoxicity of grade 3 occurred in 8 children and grade 3 cheilitis in 16 children. CONCLUSION COMBAT is a feasible and effective treatment option for patients with relapsing/refractory malignancies. The treatment is well tolerated with a low acute toxicity profile.

Abstract
Sarcomatoid carcinoma is a rare malignancy in the family of non-small-cell lung cancer. They belong to a mixed group of poorly differenciated neoplasia, including sarcomatous cells or sarcomatoid-like cells with giant or spindle cells. We report the case of a 69-year-old man with sarcomatoid carcinoma. We describe the main characteristics of these tumors. Diagnosis is frequently delayed and lesions are locally advanced. The prognostic is poorer than other non-small-cell lung cancer. Chemotherapy is often not efficient.
