Abstract
Dynamic xanthophyll cycle (XC) related non-photochemical quenching (NPQd, also called qE) is present in most phototrophs. It allows dissipating excess light energy under adverse growing conditions. Generally, NPQd rapidly reverses for photosynthesis to resume when light intensity decreases back toward optimal intensity. Under certain environmental conditions and/or in some species, NPQ can be strongly sustained (NPQs showing hours-to-days relaxation kinetics). Tisochrysis lutea is a South Pacific haptophyte phytoplankton with a strong potential for aquaculture and biotechnology applications. It was previously reported to show a surprisingly low NPQd capacity while synthesizing large amounts of diatoxanthin (Dt), a pigment involved in the XC. In order to better understand this paradox, we investigated the characteristics of NPQ in T. lutea under various growth conditions of light and nutrient availability (different photoperiods, low and high light, nutrient starvations). We found a strong NPQs, unmeasurable with usual fluorometry protocols. Along with confirming the involvement of Dt in both NPQd and NPQs (by using the dithiothreitol inhibitor), we highlighted a strong relationship between Dt and the maximum quantum yield of photochemistry (Fv/Fm) across growing conditions and during relaxation experiments in darkness. It suggests that changes in Fv/Fm, usually attributed to the 'photoinhibitory' quenching (qI), are simultaneously largely impacted by photoprotective NPQ. The overlap of xanthophyll pigments-related photoprotective NPQ with several other mechanisms involved in the cell response (Photosystem II photoinactivation, changes in pigments composition, and detoxification by antioxidants) to energy unbalance is further discussed. Our findings question both how widespread NPQs is in the global ocean, particularly in nutrient starved environments (oligotrophic waters) and situations (post-bloom), and the use of adapted active fluorescence protocols (i.e. with extended NPQ relaxation period prior to measurement).

Abstract
BACKGROUND During resection of intrinsic brain tumors in eloquent areas, particularly under awake mapping, subcortical stimulation is mandatory to avoid irreversible deficits by damaging white fiber tracts. The current practice is to alternate between subcortical stimulation with an appropriate probe and resection of tumoral tissue with an ultrasound aspiration device. Switching between different devices induces supplementary movement and possible tissue trauma, loss of time, and inaccuracies in the localization of the involved area. OBJECTIVE To use one device for both stimulation as well as a resecting tool. METHODS The tip of different ultrasound aspiration devices is currently used for monopolar current transmission (e.g., for vessel coagulation in liver surgery). We use the same circuitry for monopolar subcortical stimulation when connected with the usual stimulator devices. RESULTS We have applied this method since 2004 in over 500 patients during tumor resection with cortical and subcortical stimulation, mostly with awake language and motor monitoring. CONCLUSION A method is presented using existing stimulation and wiring devices by which simultaneous subcortical stimulation and ultrasonic aspiration are applied with the same tool. The accuracy, safety, and speed of intrinsic intracranial lesion resection can be improved when subcortical stimulation is applied.

Abstract
Background The human white matter pathway network is complex and of critical importance for functionality. Thus, learning and understanding white matter tract anatomy is important for the training of neuroscientists and neurosurgeons. The study aims to test and evaluate a new method for fiber dissection using augmented reality (AR) in a group which is experienced in cadaver white matter dissection courses and in vivo tractography. Methods Fifteen neurosurgeons, neurolinguists, and neuroscientists participated in this questionnaire-based study. We presented five cases of patients with left-sided perisylvian gliomas who underwent awake craniotomy. Diffusion tensor imaging fiber tracking (DTI FT) was performed and the language-related networks were visualized separated in different tracts by color. Participants were able to virtually dissect the prepared DTI FTs using a spatial computer and AR goggles. The application was evaluated through a questionnaire with answers from 0 (minimum) to 10 (maximum). Results Participants rated the overall experience of AR fiber dissection with a median of 8 points (mean ± standard deviation 8.5 ± 1.4). Usefulness for fiber dissection courses and education in general was rated with 8 (8.3 ± 1.4) and 8 (8.1 ± 1.5) points, respectively. Educational value was expected to be high for several target audiences (student: median 9, 8.6 ± 1.4; resident: 9, 8.5 ± 1.8; surgeon: 9, 8.2 ± 2.4; scientist: 8.5, 8.0 ± 2.4). Even clinical application of AR fiber dissection was expected to be of value with a median of 7 points (7.0 ± 2.5). Conclusion The present evaluation of this first application of AR for fiber dissection shows a throughout positive evaluation for educational purposes.

Abstract
Introduction Sexual violence (SV) is an important public health concern which may induce important and long lasting mental health problems. However, studies on SV and its mental health impact on older adults and more specifically gerontopsychiatric patients are currently lacking. Objectives This study aims to contribute to a better understanding of the prevalence, risk factors and mental health impact of SV in a gerontopsychiatric patient population. Methods Between July 2019 and March 2020 100 patients (66%F, 34%M) participated in a face to face interview on health, sexuality and wellbeing during their admission at an old age psychiatry ward in one general hospital and two psychiatric hospitals across Flanders, Belgium. Participation rate was 58%. Interviews were performed by a psychiatric trainee and especially trained master students in medicine. Results 58% (65%F; 42%M) of the participants were sexually victimised during their life, 45% (51%F, 33%F) experienced hands-off SV, 43% (48%F, 33%M) sexual abuse with physical contact and 16% (6%M, 21%F) was raped. 7% were sexually victimised in the past year. Compared with non-victimized respondents, hands-on SV victims (incl. rape) described more symptoms of depression (p=0.007) and anxiety (p=0.003) and reported lower resilience (p=0.022). Conclusions SV appears to be common in the gerontopsychiatric population and is linked to even worse mental health outcomes. These findings confirm the long-lasting mental health impact of SV and highlight the importance of attention to (sexual) trauma in mental health care in old age. Disclosure No significant relationships.

Abstract
INTRODUCTION In abdominal plastic surgery, umbilicus is frequently transposed, generating scars and shapes variating with the techniques used. Various umbilical transposition techniques have been described, all of them attempt to reproduce the "ideal" umbilicus. This study aimed to define the shape and the aesthetic results obtained with four different surgical procedures, in order to choose an "ideal" umbilical transposition technique. PATIENTS AND METHODS This retrospective study analyzed the characteristics of transposed umbilicus, in 50 patients who had undergone abdominal dermolipectomy for aesthetic reason, after a loss of weight or in breast reconstruction by Deep-Inferior-Epigastric-Perforator. Four surgical procedures were chosen, which differed by their counter-incision shape in the abdominal flap (Y, inverted Y, de-epidermized round with horizontal incision or U), and the deep points position of umbilical docking (along a horizontal or vertical axis). Shape and depth were evaluated by a panel of experts. The global assessment was based on a double evaluation, by the surgical jury and the patients themselves. RESULTS The counter-incision type determined the umbilicus shape: triangular for the Y (60%) or inverted-Y (41%), round for the U (52%) and vertical oval (67%) or round (32%) for the de-epidermized circle. The deep points position influenced the umbilicus axis. Regarding the appreciation, the de-epidermized circle had the best results for surgeons in a significant way, and for patients (respectively 72% and 100% satisfied), followed by the inverted-Y (57% and 92%) and Y techniques (55% and 89%) and at last the U (50 and 75%). CONCLUSION Horizontal counter incision in a de-epidermized round, with two anchoring points on a vertical axis, generates vertical oval or round shaped umbilicus, considered attractive in the literature, and giving the highest aesthetic satisfaction for both surgeons and patients.

Abstract
In this study, we evaluated cold atmospheric plasmas as a physical drug delivery tool for human cervical cancer HeLa cells and murine breast carcinoma 4T1 cells. Different cell exposure protocols - plasma jet, plasma treated medium, and combinations of plasma-induced electric field and plasma treated medium- have been proposed and assessed to provide new insight on plasma-induced uptake mechanism. Cell culture medium composition and volume are key parameters to achieve an efficient molecular uptake. The plasma device enabled the delivery of molecules having 150 kDa-size into 4T1cells. For the first time to our knowledge, substance uptake kinetics after plasma treatment were investigated. The percentage of positive cells for propidium iodide and an anti-cancer agent, doxorubicin, was higher when the drugs were added a few minutes after treatment. The Plasma treated medium was not found to be as efficient as direct plasma treatment in 4T1 cells while allowing an efficient delivery in HeLa cells. Uptake levels as high as 39.3 ± 2.9% and 40.1 ± 9.5% for HeLa and 4 T1 cells respectively were achieved for optimized operating conditions, for which the viability of the cells was not severely affected. We also observed that plasma treatment induced the formation of actin stress fibers into cells revealing a mechanical stress.

Abstract
By describing the experience from dispensing antiretroviral drugs to asylum seekers infected with HIV in Montreal we argue for the relational dimensions of pharmaceutical care. Between 2010 and 2016, the Government of Canada changed the medical coverage for refugees and asylum seekers, leading to some uncertainty about what types of care were reimbursable for each migrant status. In Quebec, despite the compensatory coverage provided by the provincial medical insurance board (Régie d'assurance maladie du Québec, or RAMQ), this uncertainty led to a breakdown in patient followup in some establishments. The McGill University Health Centre's Chronic Viral Illness Service (CVIS) was nevertheless able to maintain continuity of care for refugees and asylum seekers living with HIV. This article looks more specifically at the pharmaceutical care provided during this period and, more particularly, at the convergence of the technical and relational dimensions. The methodology used was a qualitative case study, which made it possible to explore pharmaceutical care, by conducting qualitative interviews (n = 16). Semistructured interviews were conducted with patients and various professionals from the CVIS, including pharmacists. The cultural, administrative, and political dimensions of pharmaceutical care described here appear very important for overall patient care. Further reflection on the importance of relational dimensions of pharmaceutical care and the place and value of pharmaceutical care in the advancement of patient care is required.

Abstract
Abstract
BACKGROUND
The postoperative outcomes and the predictors of seizure control are poorly studied for supratentorial cavernous angiomas (CA) within or close to the eloquent brain area.
OBJECTIVE
To assess the predictors of preoperative seizure control, postoperative seizure control, and postoperative ability to work, and the safety of the surgery.
METHODS
Multicenter international retrospective cohort analysis of adult patients benefitting from a functional-based surgical resection with intraoperative functional brain mapping for a supratentorial CA within or close to eloquent brain areas.
RESULTS
A total of 109 patients (66.1% women; mean age 38.4 ± 12.5 yr), were studied. Age >38 yr (odds ratio [OR], 7.33; 95% confidence interval [CI], 1.53-35.19; P = .013) and time to surgery > 12 mo (OR, 18.21; 95% CI, 1.11-296.55; P = .042) are independent predictors of uncontrolled seizures at the time of surgery. Focal deficit (OR, 10.25; 95% CI, 3.16-33.28; P < .001) is an independent predictor of inability to work at the time of surgery. History of epileptic seizures at the time of surgery (OR, 7.61; 95% CI, 1.67-85.42; P = .003) and partial resection of the CA and/or of the hemosiderin rim (OR, 12.02; 95% CI, 3.01-48.13; P < .001) are independent predictors of uncontrolled seizures postoperatively. Inability to work at the time of surgery (OR, 19.54; 95% CI, 1.90-425.48; P = .050), Karnofsky Performance Status ≤ 70 (OR, 51.20; 95% CI, 1.20-2175.37; P = .039), uncontrolled seizures postoperatively (OR, 105.33; 95% CI, 4.32-2566.27; P = .004), and worsening of cognitive functions postoperatively (OR, 13.71; 95% CI, 1.06-176.66; P = .045) are independent predictors of inability to work postoperatively.
CONCLUSION
The functional-based resection using intraoperative functional brain mapping allows safe resection of CA and the peripheral hemosiderin rim located within or close to eloquent brain areas.

Abstract
PURPOSE The practical management of cavernous angioma located within eloquent brain area before, during and after surgical resection is poorly documented. We assessed the practical pre-operative, intra-operative, and post-operative management of cavernous angioma located within eloquent brain area. METHOD An online survey composed of 61 items was sent to 26 centers to establish a multicenter international retrospective cohort of adult patients who underwent a surgical resection as the first-line treatment of a supratentorial cavernous angioma located within or close to eloquent brain area. RESULTS 272 patients from 19 centers (mean 13.6 ± 16.7 per center) from eight countries were included. The pre-operative management varied significantly between centers and countries regarding the pre-operative functional assessment, the pre-operative epileptological assessment, the first given antiepileptic drug, and the time to surgery. The intra-operative environment varied significantly between centers and countries regarding the use of imaging systems, the use of functional mapping with direct electrostimulations, the extent of resection of the hemosiderin rim, the realization of a post-operative functional assessment, and the time to post-operative functional assessment. The present survey found a post-operative improvement, as compared to pre-operative evaluations, of the functional status, the ability to work, and the seizure control. CONCLUSIONS We observed a variety of practice between centers and countries regarding the management of cavernous angioma located within eloquent regions. Multicentric prospective studies are required to solve relevant questions regarding the management of cavernous angioma-related seizures, the timing of surgery, and the optimal extent of hemosiderin rim resection.

Abstract
INTRODUCTION The existence of voluminous paralumbar perforators allows a simplification of the coverage of the lumbar region. MATERIALS AND METHODS The authors present a series about lumbar loss substance following orthopedic surgery, from 2012 to 2017. Coverage was provided by a fascio-cutaneous lumbar perforator flap. RESULTS Six patients were operated with mean age of 62.3 years, with an average follow-up of 16 months (up 6 to 41 months). Substance losses were secondary to a carcinologic excision, to a radiodermitis excision and to four debridements after infection of the operative site. In five cases, the reconstruction was performed by one lumbar perforator flap, and in one case by two lumbar perforator flaps. The average size of the substance losses was 171.91 cm2 (up 78 to 250 cm2). The average size of the flaps taken was 161 cm2 (up 50 to 250 cm2). The donor site was self-closing without sequelae. The postoperative sequences were simple and marked by a single partial necrosis of a flap, with a favorable evolution after directed healing. The quality of the cover was good with excellent trophicity. CONCLUSION Lumbar perforator helical fascio-cutaneous flaps are a reliable means of covering the loss of substances in the lumbar region. The use of these flaps makes it possible to avoid the taking of complex myo-cutaneous flaps, causing sequelae of the donor site in a location difficult to cover.

Abstract
INTRODUCTION There is a growing demand for weight loss sequelae. Some women have a particular morphology with a major trochanteric excess that warrants specific treatment. MATERIALS AND METHODS On the basis of the technique published in 1964 by Pitanguy, the authors suggest a lift of the external face of the thigh with the scar redrawing the lower part of the buttock, from the gluteal fold to the inguinal region by crossing the trochanteric region. Eleven cases of major trochanteric excess after slimming are presented. In 4 cases, the trochanteric excess is solely treated by trochanteric under gluteus lift. In 7 cases, it is associated with abdominoplasty to perform a trochanteric under gluteus bodylifting. RESULTS Complications and results are presented. The trochanterian excess is reduced, the buttock is harmonious and the patients satisfied. DISCUSSION Modifications are made to the much criticized technique of Pitanguy. The lipectomy replaces the monobloc resection, the scar is verticalized on the trochanter to join the abdominoplasty scar. This technique is an alternative to the vertical trochanteric resection associated with classic bodylift. CONCLUSION The trochanteric under gluteus lift is an elegant solution for treating large trochanteric excess. It is adaptable. It can become bodylifting TSF in the cases of great slimming.

Abstract
INTRODUCTION The management of hidradenitis suppurativa is multidisciplinary, involving general measures, medical treatment and surgery. Non-surgical treatments, often first-line procedures, mainly concern forms of low-to-moderate severity or, conversely, very severe forms in non-operable patients or those refusing surgery. While many treatments have been attempted, few randomized controlled trials have been conducted, so the choice of treatments is most often based on the personal experience of the clinicians. The objective of this systematic review is to propose a synthetic analysis of the currently available non-surgical procedures. METHODS This systematic review of the literature was conducted in accordance with the PRISMA criteria. We searched for articles in the Medline®, PubMed Central, Embase and Cochrane databases published between January 2005 and September 2015. RESULTS Sixty-four articles were included. They generally had a low level of evidence; indeed, the majority of them were retrospective observational studies. They involved biotherapy (44%), dynamic phototherapy (16%), antibiotics (11%), Laser (8%), retinoids (6%) and immunosuppressive therapies, anti-inflammatory drugs, zinc, metformin, gammaglobulins and fumarates. CONCLUSIONS None of the non-surgical treatments can treat all stages of the disease and offer long-term remission. Antibiotics and biotherapy seem to have real effectiveness but their effect remains suspensive and the disease is almost certain to reappear once they are stopped. As regards antibiotics, no association has shown their superiority in a study with a high level of evidence. And while some biotherapies seem quite effective, due to their side effects they should be reserved for moderate-to-severe, resistant or inoperable forms of the disease. Randomized controlled studies are needed before valid conclusions can be drawn. In the resistant or disabling forms, it is consequently advisable to orientate to the greatest possible extent towards radical surgery, which is the only treatment allowing hope for cure.

Abstract
The calcium-activated neutral proteinase 1 (CAPN1) gene, which encodes µ-calpain, is considered to be associated with the majority of meat-quality traits. The objective of the present study was to evaluate the effect of CAPN1 polymorphism on the most important slaughter, fattening and pork-quality traits. The genotype frequency of g.1429G>A polymorphism was estimated on 860 pigs represented by five breeds (Polish Landrace, Polish Large White, Pietrain, Duroc and Pulawska). In all breeds, the most frequent were pigs with an AA genotype (60–74%), with the exception of Duroc pigs where the largest number of GG animals was observed (14%). The results showed that g.1429G>A polymorphism significantly affected the number of days on test (P ≤ 0.05) and age at slaughter (P ≤ 0.01), the weight of ham and primary cuts (P ≤ 0.05, P ≤ 0.01 respectively), loin eye area (P ≤ 0.01) and average backfat thickness (P ≤ 0.05). The g.1429G>A single-nucleotide polymorphism showed no clear influence on complex pork-quality traits. At the present stage of research, the results obtained allow for the use of g.1429G>A polymorphism in CAPN1 gene as genetic marker in pig selection to improve several slaughter or fattening traits.

Abstract
Many studies have been conducted on the environmental impacts of combustion generated aerosols. Due to their complex composition and morphology, their chemical reactivity is not well understood and new developments of analysis methods are needed. We report the first demonstration of in-flight X-ray based characterizations of freshly emitted soot particles, which is of paramount importance for understanding the role of one of the main anthropogenic particulate contributors to global climate change. Soot particles, produced by a burner for several air-to-fuel ratios, were injected through an aerodynamic lens, focusing them to a region where they interacted with synchrotron radiation. X-ray photoelectron spectroscopy and carbon K-edge near-edge X-ray absorption spectroscopy were performed and compared to those obtained for supported samples. A good agreement is found between these samples, although slight oxidation is observed for supported samples. Our experiments demonstrate that NEXAFS characterization of supported samples provides relevant information on soot composition, with limited effects of contamination or ageing under ambient storage conditions. The highly surface sensitive XPS experiments of airborne soot indicate that the oxidation is different at the surface as compared to the bulk probed by NEXAFS. We also report changes in soot's work function obtained at different combustion conditions.

Abstract
BACKGROUND Awake craniotomy is currently considered the gold standard to maximise the extent of resection and to minimise postoperative deficits in patients with supratentorial tumours near eloquent areas. In addition to direct electrical stimulation (DES) of the cortex, intraoperative subcortical mapping is increasingly used as it optimises the benefit-to-risk ratio by decreasing (permanent) postoperative neurological deficits. However, only little attention has been paid to subcortical mapping procedures and especially the tasks to be used. METHODS In this article, language and non-language testing at the subcortical level is described and discussed by means of three right-handed cases with a glioma in the left hemisphere. To assess subcortical functions, a multimodal test named the Quick Mixed Test was developed (QMT). Pre-, intra- and postoperative test results are described and discussed in detail. RESULTS Based on the analysis of these preliminary observations, a number of clinical recommendations for intraoperative subcortical mapping may be made: (1) the selection of a set of language and non-language tests needs to be tailored according to the functional corticosubcortical regions affected by the tumoral lesion and the patient's characteristics (job/hobby/daily life activities); (2) language and non-language tests should be presented in a multimodal and alternating way during subcortical stimulation since this approach enables screening various functions simultaneously or in a very short period of time and (3) spontaneous speech is a useful adjunct to standardised tests since it most resembles daily life conversation. CONCLUSION Administration of multimodal tests during subcortical DES such as the experimental QMT may facilitate identification of eloquent pathways leading to avoidance of permanent neurological impairments.

Abstract
PURPOSE The objectives of this paper is to study the prevalence of breastfeeding in Brussels, to assess whether the targets of the Maternal and Child Health program (MCH) were met (prevalence's of breastfeeding of 85 and 75% of exclusive breastfeeding) and finally to identify factors associated with exclusive breastfeeding at the birth. MATERIALS AND METHOD The cross-sectional survey is representative of children 18 to 24 months living in Brussels. Data on breastfeeding are anamnestic and retrospective. A face to face questionnaire was administered by trained investigators, 16 questions about breastfeeding as well socio-demographic information were collected from 544 mothers. The survey took place in 2012. RESULTS At the birth, 83.3% (95% CI 80.1-86.4) of mothers exclusively breastfed and 9.7% of the mothers (7.3-12.2) partially. When discharged from maternity unit, 80.9% (77.6-84.2) of mothers breastfed exclusively and 9.7% (7.3-12.2) partially. When fitting a logistic model, predictors associated with exclusive breastfeeding at the birth were gestation, type of birth, father's education level and the main influencing factor was the partner's attitude. DISCUSSION The targets of the MCH were reached in Brussels. Until now, transversal surveys are the only way of knowing the prevalence and the factors associated with breastfeeding in Brussels. These first representative data on breastfeeding came from the 2012 vaccine coverage survey. Given the primary role of the father in choosing a breastfeeding it is necessary that the father is more often taken into account in regard to the promotion of AM during the prenatal period. A rigorous use of definitions of AM should be systematized.

Abstract
Intraoperative direct electrical stimulation (DES) is increasingly used in patients operated on for tumours in eloquent areas. Although a positive impact of DES on postoperative linguistic outcome is generally advocated, information about the neurolinguistic methods applied in awake surgery is scarce. We developed for the first time a standardised Dutch linguistic test battery (measuring phonology, semantics, syntax) to reliably identify the critical language zones in detail. A normative study was carried out in a control group of 250 native Dutch-speaking healthy adults. In addition, the clinical application of the Dutch Linguistic Intraoperative Protocol (DuLIP) was demonstrated by means of anatomo-functional models and five case studies. A set of DuLIP tests was selected for each patient depending on the tumour location and degree of linguistic impairment. DuLIP is a valid test battery for pre-, intraoperative and postoperative language testing and facilitates intraoperative mapping of eloquent language regions that are variably located.

Abstract
PURPOSE The objectives of this paper were to study the prevalence of breastfeeding in the French-speaking community of Belgium, to assess whether the targets of the Maternal and Child Health program (MCH) were met (prevalence of breastfeeding of 85, 70, 50, and 25% at the maternity hospital and at 3, 6, and 12 months of age, respectively), and to identify factors associated with breastfeeding at the maternity hospital and at 6 months of age. MATERIALS AND METHODS A sample (two-stage cluster sampling) was drawn from the population of children aged 18-24 months living in the area. A face-to-face questionnaire was administered by trained investigators. Anamnestic data on breastfeeding at the maternity hospital and at 3, 6, and 12 months as well sociodemographic information were collected from 522 mothers. The survey took place in 2009. RESULTS At the maternity hospital, 75.7% (95%CI [72.7-79.5]) of the mothers were breastfeeding: 72.4% among the Belgians (and French) and 89.0% among foreign mothers. At 3 months of age, the breastfeeding prevalence was 48.3% (CI, 44.0-52.6): 42.5% among the Belgians (and French) and 72.0% among foreign mothers (p<0.001). At 6 months of age, 26.0% of the mothers were breastfeeding (CI, 22.3-29.8): 19.3% among the Belgians (and French) and 53.0% among foreign mothers (p<0.001). At 12 months of age, 10.0% (CI, 7.4-12.5) of the mothers were breastfeeding: 4.8% among the Belgians (and French) and 31.0% among the foreign mothers (p<0.001). When fitting a logistic model, the predictors associated with breastfeeding at the maternity hospital were educational level, nationality of birth, and parity. At 6 months, logistic models were fitted separately in the two strata. Among the Belgians, the level of education and attending a MCH consultation were significantly associated with breastfeeding. In the stratum of foreign mothers, the only factor associated with breastfeeding was working time. No association was observed between breastfeeding and the mother's age at the maternity hospital or at 6 months. DISCUSSION The targets of the MCH were not reached in Belgian and French mothers, while they were in mothers of other nationalities. Until now, transversal surveys have been the only way of knowing the prevalence and the factors associated with breastfeeding in the French-speaking community of Belgium. These first representative data on breastfeeding came from the 2009 vaccine coverage survey.

Abstract
We have investigated multiphoton multiple ionization dynamics of xenon atoms using a new x-ray free-electron laser facility, SPring-8 Angstrom Compact free electron LAser (SACLA) in Japan, and identified that Xe(n+) with n up to 26 is produced at a photon energy of 5.5 keV. The observed high charge states (n≥24) are produced via five-photon absorption, evidencing the occurrence of multiphoton absorption involving deep inner shells. A newly developed theoretical model, which shows good agreement with the experiment, elucidates the complex pathways of sequential electronic decay cascades accessible in heavy atoms. The present study of heavy-atom ionization dynamics in high-intensity hard-x-ray pulses makes a step forward towards molecular structure determination with x-ray free-electron lasers.

Abstract
A project implemented within the framework of the International Clearinghouse for Birth Defect Monitoring Systems is named MADRE: MAlformation DRug Exposure surveillance. The idea is to survey the simultaneous occurrence of malformations and first-trimester drug exposures. In a 2-year period 1990-91, this has yielded 1448 infants known to have been exposed to drugs and that are known to have malformations. Cases have been reported by eight programs: Australia, Central-East France, Israel, Italy IPIMC, Italy IMER, Japan Red Cross Hospitals, Japan Maternal Health and Welfare, and South America. By searching this databank for associations between drugs and malformations, specific relationships can be detected.The 9th revision of the WHO International Classification of Diseases, adapted by the British Paediatric Association, known as ICD9/BPA is used for coding malformations. This is a hierarchical system with 5 digits as the maximum level of specification of each malformation.The ATC (Anatomical Therapeutic Chemical) classifications system is used for coding drugs. This is a multiple level, hierarchical classification with up to 7 digits for specifying each drug.Up to five drugs and malformations are coded for each case using ATC and ICD9/BPA classifications, and all observed drug-malformation pairs form the basis for the analysis. For each drug-malformation combination where three or more cases are observed, a set of 2×2 tables is formed and analyzed as in case-control studies. The odds ratio for the pair, stratified for program, gives the relative risk for the malformation in question, comparing use of the specific drug with all other drugs.Well known or controversial associations were tested in the collected material, and at this stage only one new association is suggested, that is between cardiac defects and maternal treatment with thyroid hormones. This finding has to be further explored with new data.

Abstract
Mothers of boys with hypospadias and control mothers were interviewed in eight malformation monitoring programs around the world. Hormone therapy was used quite frequently in five but rarely in three of the programs. The odds ratio for hypospadias after hormone therapy during pregnancy was 2.8 (95% confidence limits 1.2, 6.9) but there was no correlation between the timing of hormone therapy and the location of the urethral orifice, nor between the severity of the malformation and hormone therapy. Programs with the highest hormone exposure rate showed the lowest odds ratio for pregnancy bleeding, the most common reason for hormone therapy. These latter findings cast doubts on the causal association between hormone therapy and isolated hypospadias. Alternative explanations are recall or interviewer bias or unidentified confounders.

Abstract
Surgical treatment of pyelo-ureteric junction syndromes was classically at the child's, a pyeloplasty by posterior way or by lombotomy. For several years, assisted video techniques are proposed for this gesture. The purpose of our study was to compare the lombo-assisted pyeloplasty procedure with the lombotomy procedure, within the framework of this coverage. We made a retrospective study of procedures performed from January 2000 to December 2005, based on a file review of children operated for pyelo-ureteric junction syndrome. Children under the age of 2 years were excluded. Fifty-two children were divided in 2 groups: group 1: 24 children, 7 girls and 17 boys, average age of 86 months (extremes: 27-172) benefited from a lombo-assisted pyeloplasty. Group 2: 28 children, 12 girls and 16 boys, average age of 69 months (extremes: 24-129) benefited from a pyeloplasty by lombotomy. Operating times were significantly shorter in opened surgery than with the lombo-assisted procedure. There was no significant difference in terms of per- or post-operating complication, use of analgesic and hospitalization duration. On the other hand, the lombo-assisted procedure provided the same undisputable aesthetic benefit and the same muscular preservation than pure lomboscopy procedure. As a consequence, this procedure could be set up at no risk for the patient, even if it had lead to longer operating times. However, operating times stayed shorter than with the pure lomboscopy or the celioscopy procedures, compared to the literature.

Abstract
Few genomic tools are available in ducks. To produce some new resources, we have designed Pekin (Anas platyrhynchos) and Muscovy (Cairina moschata) duck-specific primers for 22 genes involved mainly in lipid metabolism, and to a lesser extent in carbohydrate metabolism and other functions. Primers were designed according to duck sequences when available and otherwise from the corresponding conserved regions in chicken and human sequences. These primers allowed quantitative RT-PCR amplification of RNA from Pekin and Muscovy ducks. Amplified cDNA products from both species were sequenced and were found to be very similar to chicken sequences (about 94%). This work provides additional genomic resources and polymorphism information for some genes in duck species and represents a first step towards gene expression analyses in Pekin and Muscovy ducks.

Abstract
This paper reports an analysis of trisomy 18 in Sweden between 1978 and 1987 and a comparison with data from the Rhône-Alpes/Auvergne registry in France. A strong maternal age dependency is seen, which parallels that observed for Down syndrome. The patterns of registered malformations in the two data sets are quite similar. A progressive increase of the prevalence at birth of trisomy 18 is seen in Sweden during the ten years but not in France. This increase seems to result, at least in part, from an increased identification of the trisomy among malformed infants. A parallel decrease in the reporting of infants with the "cardinal" trisomy 18 malformations is indicated.

Abstract
Congenital erythropoietic porphyria (CEP) is a recessive autosomal disorder characterized by a deficiency in uroporphyrinogen III synthase (UROS), the fourth enzyme of the heme biosynthetic pathway. The severity of the disease, the lack of specific treatment except for allogeneic bone marrow transplantation, and the knowledge of the molecular lesions are strong arguments for gene therapy. An animal model of CEP has been designed to evaluate the feasibility of retroviral gene transfer in hematopoietic stem cells. We have previously demonstrated that the knockout of the Uros gene is lethal in mice (Uros(del) model). This work describes the achievement of a knock-in model, which reproduces a mutation of the UROS gene responsible for a severe UROS deficiency in humans (P248Q missense mutant). Homozygous mice display erythrodontia, moderate photosensitivity, hepatosplenomegaly, and hemolytic anemia. Uroporphyrin (99% type I isomer) accumulates in urine. Total porphyrins are increased in erythrocytes and feces, while Uros enzymatic activity is below 1% of the normal level in the different tissues analyzed. These pathological findings closely mimic the CEP disease in humans and demonstrate that the Uros(mut248) mouse represents a suitable model of the human disease for pathophysiological, pharmaceutical, and therapeutic purposes.

Abstract
OBJECTIVE To identify in a follow up study airway changes occurring during the course of a sport season in healthy endurance athletes training in a Mediterranean region. METHODS Respiratory pattern and function were analysed in 13 healthy endurance trained athletes, either during a maximal exercise test, or at rest and during recovery through respiratory manoeuvres (spirometry and closing volume tests). The exercise test was conducted on three different occasions: during basic endurance training and then during the precompetition and competitive periods. RESULTS During the competitive period, a slight but non-clinically significant decrease was found in forced vital capacity (-3.5%, p = 0.0001) and an increase in slope of phase III (+25%, p = 0.0029), both at rest and after exercise. No concomitant reduction in expiratory flow rates was noticed. During maximal exercise there was a tachypnoeic shift over the course of the year (mean (SEM) breathing frequency and tidal volume were respectively 50 (2) cycles/min and 3.13 (0.09) litres during basic endurance training v 55 (3) cycles/min and 2.98 (0.10) litres during the competitive period; p < 0.05). CONCLUSIONS This study does not provide significant evidence of lung function impairment in healthy Mediterranean athletes after one year of endurance training.
