Abstract
BACKGROUND Surgical approaches to the equine rectum and perirectal area are described in the literature. However, surgeries in this region can be challenging. OBJECTIVE To describe the surgical anatomy of the presacral space and to evaluate its access using a retroperitoneoscopic approach. STUDY DESIGN Ex vivo experiment. METHODS Preliminary dissections were performed in two cadavers to define the boundaries of the presacral space and to determine portal locations for the surgical approach. After that, nine cadavers were used for experimental presacral retroperitoneoscopic procedure in a standing position. Following retroperitoneoscopy, cadavers were dissected to confirm the anatomical structures observed during the endoscopic procedures, to control the location of each portal and to record iatrogenic trauma. RESULTS The presacral space was bordered by the vertebral column from the ventral aspect of lumbosacral promontorium to the first coccygeal vertebra dorsally and by the presacral fascia and peritoneum ventrally. Lateral limits were composed of the sacrosciatic ligament and transversalis fascia. Cranial and caudal borders were composed of the peritoneum and coccygeal and levator ani muscles respectively. Retroperitoneoscopic portals were placed between the external anal sphincter and semimembranosus muscles and between the base of the tail and the external anal sphincter muscle through the anococcygeal fascia to enter the space by its caudal border. The retroperitoneal space was reached in all cases and the dorsal and lateral aspects of the rectum were visualised after creation of a working space. MAIN LIMITATIONS Use of cadaver specimens do not permit to evaluate the tolerance in living animals and the surgical complications such as rectal damage, haemorrhage and infection. CONCLUSION This study provides an anatomical description and surgical access of the presacral space with a minimal invasive approach. Retroperitoneoscopy allows access to the rectum and the dorsal aspect of the pelvis.

Abstract
A total of 752 horses were involved in the CES Valencia Spring Tour 2021. Due to an equine herpesvirus-1 (EHV-1) outbreak, the competition was cancelled and the site was locked down. The objective of this study was to describe epidemiological, clinical, diagnostic, and outcome data of the 160 horses remaining in Valencia. Clinical and quantitative polymerase chain reaction (qPCR) data were analysed for 60 horses in a retrospective case-control observational study. The risk of developing clinical manifestations was explored using a logistic regression approach. EHV-1 was detected by qPCR, genotyped as A2254 (ORF30) and isolated on cell culture. From the 60 horses, 50 (83.3%) showed fever, 30 horses (50%) showed no further signs and 20 (40%) showed neurological signs, with eight horses (16%) hospitalised, of which two died (3%). Stallions and geldings were six times more likely to develop EHV-1 infection compared to mares. Horses older than 9 years, or housed in the middle of the tent were more likely to develop EHV-1 myeloencephalopathy (EHM). These data show that for EHV-1 infection, the risk factor was male sex. For EHM the risk factors were age > 9-year old and location in the middle of the tent. These data highlight the crucial role of stable design, position, and ventilation in EHV-outbreaks. It also showed that PCR testing of the horses was important to manage the quarantine.

Abstract
BACKGROUND Surgical approaches to the kidneys and perirenal structures are uncommonly performed in horses and several complications have been described with the current procedures. OBJECTIVE To describe the anatomy of the retroperitoneal perirenal space and investigate a retroperitoneal minimally invasive approach to access the kidney and perirenal structures in horses. STUDY DESIGN Descriptive, cadaveric study. METHODS Anatomical description of the retroperitoneal space was performed on three equine cadavers and the surgical approach was developed based on these dissections. Ten cadaveric horses underwent a retroperitoneoscopy. Five horses were placed in a right lateral recumbency position to explore the left retroperitoneal space and five horses were placed in a standing position to explore both left and right sides. Anatomical landmarks, working space and access to the renal hilus and perirenal structures were evaluated. RESULTS Dissections revealed that kidneys are surrounded by a renal fascia which delimits two spaces: a perirenal space between the kidney and the renal fascia, and a pararenal space between the renal fascia and psoas muscles or peritoneum. The retroperitoneoscopic portal was placed at the level of the dorsal aspect of the tuber coxae, 3 cm caudal to the last rib for the left side and 2 cm caudal to the last rib for the right side. Retroperitoneal access and working space were successfully established in all horses. The standing position allowed an easier dissection than lateral recumbency. Division of the perirenal fat allowed access to the kidney and adrenal glands as well as individualisation of renal vessels and ureter in the renal hilus. MAIN LIMITATIONS Study of cadavers precluded appreciation of haemorrhage or use the pulsating vessels as landmarks. CONCLUSIONS This study provides a description of the retroperitoneal perirenal space and describes a new surgical approach to access kidneys and perirenal structures in horses.

Abstract
The various roles of membrane lipids in human health has urged researchers to study their impact in neuropsychiatric diseases, especially in schizophrenia spectrum disorders and more recently in early stages of psychosis. The progress in mass spectrometry technologies now allows a more comprehensive analysis of phospholipids (PL) and their fatty acid (FA) molecular species. FA are defined by a carbon chain of variable length and are said to be unsaturated when their chain has one or more carbon-carbon double bonds. The PL are composed of a hydrophilic polar head with a phosphoric acid group and an hydrophobic part with FAs; they encompass glycerophospholipids and sphingolipids. The plasma membrane is a complex and dynamic structure consisting of a lipid bilayer composed of an outer layer and an inner layer of specific lipid composition. The permanent remodeling of membrane lipids involves phospholipases especially the phospholipase A2. Seventy percent of the brain consists of lipids from different classes and molecular species. Most of the brain lipids are composed of polyunsaturated fatty acid (PUFA)-enriched diacyl classes where omega-3 and omega-6 molecular species predominate. The balance between omega-3 and omega-6 is important for the neurodevelopment. PUFA are also involved in neurogenesis and neurotransmission. Sphingomyelin (SM) is a sphingolipid that influences inflammation, cell proliferation and lipid rafts formation. It is an important component of myelin sheaths of white matter and therefore is involved in cerebral connectivity. In rat models, deficiency in omega-3 causes abnormalities in dopaminergic neurotransmission, impacts on the functioning of some receptors (including cannabinoids CB1, glutamatergic N-methyl-D-aspartate receptor, NMDA), and increases sensitivity to hallucinogens. In contrast, omega-3 supplementation improves cognitive function and prevents psychotic-like behavior in some animal models for schizophrenia. It also reduces oxidative stress and prevents demyelination. The historical membrane hypothesis of schizophrenia has led to explore the lipids abnormality in this disorder. This hypothesis was initially based on the observation of an abnormal membrane prostaglandin production in schizophrenia caused by a membrane arachidonic acid deficiency. It has evolved emphasizing the various PUFA membrane's roles in particular regarding oxidative stress, inflammation and regulation of the NMDA receptors. In patients with mental disorders, low omega-3 index is more frequent than in the general population. This lipid abnormality could lead to myelination abnormalities and cognitive deficits observed in patients. It could also participate in oxidative stress abnormalities and inflammation reported in schizophrenia. On the other hand, low omega-3 index deficit was reported to be associated with an increased cardiovascular risk, and omega-3 supplementation may also have a positive cardiovascular impact in psychiatric patients, even more than in the general population. The presence of membrane lipid abnormalities is also found in patients during the first psychotic episode (FEP). The omega-3 supplementation improved the recovery rate and prevented the loss of gray matter in FEP. In patients at ultra-high risk to develop a psychotic disorder (UHR), omega-3 supplementation has been associated with a reduction of the rate of conversion to psychosis and with metabolic changes, such as decreased activity of phospholipase A2. However, this study has not as yet been replicated. Not all patients exhibit lipid abnormalities. Several studies, including studies from our team, have found a bimodal distribution of lipids in patients with schizophrenia. But some studies have found differences (in PUFA) in the acute phase whereas our studies (on phospholipids) are in chronic phases. It will be interesting to study in more depth the links between these two parameters. Furthermore, we identified a subgroup which was identified with a deficit in sphingomyelin and PUFA whereas others have found an increase of sphingomyelin. Individuals with this abnormal lipid cluster had more cognitive impairments and more severe clinical symptoms. Because the niacin test is an indirect reflection of arachidonic acid levels, it has been proposed to identify a subset of patients with membrane lipids anomalies. Niacin test response is influenced by several factors related to lipid metabolism, including cannabis use and phospholipase A2 activity. Despite progress, the function and impact of membrane lipids are still poorly understood in schizophrenia. They could serve as biomarkers for identifying biological subgroups among patients with schizophrenia. In UHR patients, their predictive value on the conversion to psychosis should be tested. Omega-3 supplementation could be a promising treatment thanks to its good tolerance and acceptability. It could be more appropriate for patients with PUFA anomalies in a more personalized medical approach.

Abstract
BACKGROUND There are no data investigating the effect of systemic morphine on the size of the stomach or the food consumption in horses. OBJECTIVES To evaluate gastrointestinal side effects of morphine administered systemically in healthy horses by the means of clinical and ultrasonographic evaluations. STUDY DESIGN In vivo experiment. METHODS On day 1 of the experiment, six healthy French Trotter mares were evaluated clinically and an abdominal ultrasonography was performed three times 4 h apart to record the size of the stomach, the number of contractions per minute of the duodenum, jejunum, caecum, left and right ventral colons. On Day 2, morphine was administered three times 4 h apart at the dose of 0.1 mg/kg i.v. and the same ultrasonographic examinations performed. On Day 3, only clinical and ultrasonographic examinations were performed as on Day 1. Amounts of hay and water ingested, frequency and weight of faeces were recorded throughout the study. RESULTS Number of contractions of the duodenum, caecum, left and right ventral colons were significantly decreased after morphine administration. Size of the stomach was increased significantly with a cumulative effect of repeated doses of morphine. Hay (+0.4 kg/h, P<0.001) and water (+1.1 L/h, P<0.001) consumption were significantly increased. MAIN LIMITATIONS The study was performed in healthy horses. CONCLUSIONS Systemic morphine administration causes gastrointestinal depression, gastric distention and hyperphagia in horses. Clinical and ultrasonographical examinations are valuable tools to identify side effects of morphine administration in horses. Further studies are needed to assess side effects and monitoring in clinically painful cases. Horses receiving systemic morphine administration should be closely monitored for signs of gastric distention and, specifically, the amount of food given while receiving treatment should be controlled to avoid complications.

Abstract
Localization of uranium within cells is mandatory for the comprehension of its cellular mechanism of toxicity. Secondary Ion Mass Spectrometry (SIMS) has recently shown its interest to detect and localize uranium at very low levels within the cells. This technique requires a specific sample preparation similar to the one used for Transmission Electronic Microscopy, achieved by implementing different chemical treatments to preserve as much as possible the living configuration uranium distribution into the observed sample. This study aims to compare the bioaccumulation sites of uranium within liver or kidney cells after chemical fixation and cryomethods preparations of the samples: SIMS analysis of theses samples show the localization of uranium soluble forms in the cell cytoplasm and nucleus with a more homogenous distribution when using cryopreparation probably due to the diffusible portion of uranium inside the cytoplasm.

STUDY DESIGN Multicentre retrospective case series. METHODS Case records of horses diagnosed with MICET fractures that had undergone surgical treatment were reviewed. Follow-up information was obtained from re-examination visits and/or owners. RESULTS Twenty-one cases were identified at 9 equine hospitals between 2004 and 2016. A history of trauma and acute onset of lameness was reported in 12 horses. All cases underwent fracture removal via arthroscopy of the medial femorotibial joint. The cranial cruciate ligament was intact in 6 horses and damaged in 15 horses (damage was ≤25% [n = 9], 25-50% [n = 4] or ≥50% [n = 2] of the cross-sectional area). The cranial ligament of the medial meniscus was damaged in 11 horses (≤25% [n = 8], 25-50% [n = 3]). The medial meniscus was damaged in 5 horses and articular cartilage damage was identified in 14 horses (mild [n = 8], moderate [n = 6]). Follow-up information (median 14 months; 4 months-6 years) was available for 20 cases; 2 horses were sound but convalescing; 13 horses were sound and returned to their previous or expected use. Of the 4 horses with the most severe changes to the articular soft tissue structures, 2 remained lame and 2 were subjected to euthanasia because of persistent lameness. MAIN LIMITATIONS The retrospective, multicentre nature of this study and the limited number of horses are the main limitations. CONCLUSIONS Fractures of the MICET are commonly associated with a traumatic event. Prompt diagnosis and early arthroscopic removal of the fracture are recommended.

Abstract
Schizophrenia is a severe mental condition in which several lipid abnormalities-either structural or metabolic-have been described. We tested the hypothesis that an abnormality in membrane lipid composition may contribute to aberrant dopamine signaling, and thereby symptoms and cognitive impairment, in schizophrenia (SCZ) patients. Antipsychotic-medicated and clinically stable SCZ outpatients (n=74) were compared with matched healthy subjects (HC, n=40). A lipidomic analysis was performed in red blood cell (RBC) membranes examining the major phospholipid (PL) classes and their associated fatty acids (FAs). Clinical manifestations were examined using the positive and negative syndrome scale (PANSS). Cognitive function was assessed using the Continuous Performance Test, Salience Attribution Test and Wisconsin Card Sorting Test. Sphingomyelin (SM) percentage was the lipid abnormality most robustly associated with a schizophrenia diagnosis. Two groups of patients were defined. The first group (SCZ c/SM-) is characterized by a low SM membrane content. In this group, all other PL classes, plasmalogen and key polyunsaturated FAs known to be involved in brain function, were significantly modified, identifying a very specific membrane lipid cluster. The second patient group (SCZ c/SM+) was similar to HCs in terms of RBC membrane SM composition. Compared with SCZ c/SM+, SCZ c/SM- patients were characterized by significantly more severe PANSS total, positive, disorganized/cognitive and excited psychopathology. Cognitive performance was also significantly poorer in this subgroup. These data show that a specific RBC membrane lipid cluster is associated with clinical and cognitive manifestations of dopamine dysfunction in schizophrenia patients. We speculate that this membrane lipid abnormality influences presynaptic dopamine signaling.

Abstract
OBJECTIVE To describe a laparoscopic technique for evaluating umbilical disorders in calves, including feasibility, visualization of umbilical structures, and related complications. STUDY DESIGN Prospective clinical study. ANIMALS Male calves (15 Holstein, 2 Montbeliard) with umbilical disorders (n=17). METHODS Calves <2 months old with obvious umbilical disease were assessed by clinical examination and ultrasonography of the umbilical structures. Laparoscopic evaluation was performed in dorsal recumbency under subarachnoid lumbosacral anesthesia and sedation. An open insertion technique with short 60 mm cannulas was used after creating 2 portals 10 cm cranial to the umbilicus (one 5 cm left of midline for the laparoscope and one 5 cm right of midline as an instrument portal). After laparoscopy, abnormal tissues were resected by laparotomy during the same anesthetic period. RESULTS Laparoscopic evaluation of umbilical structures was performed quickly (mean surgery time 7.1 ± 2.5 minutes). Umbilical structures could be completely visualized in all calves without intraoperative complications. In addition to abnormalities previously detected on ultrasound, laparoscopy enabled detection of adhesions 7 calves that were not suspected on ultrasound, as well as focal enlargements of the umbilical arteries and urachus close to the bladder in 5 calves. Laparoscopy failed to detect abnormalities observed with ultrasound or laparotomy in 4 calves, including small hernias and omphalitis. CONCLUSION Laparoscopic evaluation of umbilical structures was performed safely and quickly in young calves and allowed complete evaluation of intra-abdominal umbilical structures and may, therefore, be a useful adjunct to physical examination and ultrasound to fully assess the abdomen in calves.

Abstract
The objective of the study was to evaluate the effect of ligation of the ipsilateral common carotid artery (CCA) combined with various antimycotic treatments for the prevention of epistaxis in horses with guttural pouch mycosis. For each case, ipsilateral ligation of the CCA was performed, followed by application of various topical medications under endoscopic guidance. Frequency and number of treatments, outcome and recurrence of haemorrhage were retrospectively recorded. Twenty-four horses were included. Topical medication was administered by detachment of the diphtheric membrane and spraying (n=16) or by intralesional injection directly in the plaques using a transendoscopic needle (n=8). Epistaxis recurred in five horses (20.8 per cent), causing death of four horses (16.6 per cent). The mean number of treatments was 6.3±4.0 (range 2-14) for all topical treatments. Ligation of the ipsilateral CCA and topical medication carries a fair prognosis for avoidance of recurrent episodes of epistaxis, but fatal haemorrhage can occur. Removal of the fungal plaque and topical treatment of the underlying lesion appeared to speed up resolution of the mycotic mucosal lesions. The described technique is a salvage procedure when financial or technical constraints prevent the use of transarterial catheter occlusion techniques.

Abstract
The understanding of the functional role of the lipid diversity in biological membranes is a major challenge. Lipid models have been developed to address this issue by using lipid mixtures generating liquid-ordered (Lo)/liquid-disordered (Ld) immiscibility. The present study examined mixtures comprising Egg sphingomyelin (SM), cholesterol (chol) and phosphatidylcholine (PC) either containing docosahexaenoic (PDPC) or oleic acid (POPC). The mixtures were examined in terms of their capability to induce phase separation at the micron- and nano-scales. Fluorescence microscopy, electron spin resonance (ESR), X-ray diffraction (XRD) and calorimetry methods were used to analyze the lateral organization of the mixtures. Fluorescence microscopy of giant vesicles could show that the temperature of the micron-scale Lo/Ld miscibility is higher for PDPC than for POPC ternary mixtures. At 37°C, no micron-scale Lo/Ld phase separation could be identified in the POPC containing mixtures while it was evident for PDPC. In contrast, a phase separation was distinguished for both PC mixtures by ESR and XRD, indicative that PDPC and POPC mixtures differed in micron vs nano domain organization. Compared to POPC, the higher line tension of the Lo domains observed in PDPC mixtures is assumed to result from the higher difference in Lo/Ld order parameter rather than hydrophobic mismatch.

Abstract
Uranium is a heavy metal naturally found in the earth's crust that can contaminate the general public population when ingested. The acute effect and notably the uranium nephrotoxicity are well known but knowledge about the effect of chronic uranium exposure is less clear. In a dose-response study we sought to determine if a chronic exposure to uranium is toxic to the kidneys and the liver, and what the anti-oxidative system plays in these effects. Rats were contaminated for 3 or 9 months by uranium in drinking water at different concentrations (0, 1, 40, 120, 400, or 600 mg/L). Uranium tissue content in the liver, kidneys, and bones was linear and proportional to uranium intake after 3 and 9 months of contamination; it reached 6 μg per gram of kidney tissues for the highest uranium level in drinking water. Nevertheless, no histological lesions of the kidney were observed, nor any modification of kidney biomarkers such as creatinine or KIM-1. After 9 months of contamination at and above the 120-mg/L concentration of uranium, lipid peroxidation levels decreased in plasma, liver, and kidneys. Glutathione concentration increased in the liver for the 600-mg/L group, in the kidney it increased dose dependently, up to 10-fold, after 9 months of contamination. Conversely, chronic uranium exposure irregularly modified gene expression of antioxidant enzymes and activities in the liver and kidneys. In conclusion, chronic uranium exposure did not induce nephrotoxic effects under our experimental conditions, but instead reinforced the antioxidant system, especially by increasing glutathione levels in the kidneys.

Abstract
Genetic predispositions for guttural pouch tympany, recurrent laryngeal neuropathy and recurrent airway obstruction (RAO) are well documented. There is also evidence that exercise-induced pulmonary haemorrhage and infectious diseases of the respiratory tract in horses have a genetic component. The clinical expression of equine respiratory diseases with a genetic basis results from complex interactions between the environment and the genetic make-up of each individual horse. The genetic effects are likely to be due to variations in several genes, i.e. they are polygenic. It is therefore unlikely that single gene tests will be diagnostically useful in these disorders. Genetic profiling panels, combining several genetic factors with an assessment of environmental risk factors, may have greater value, but much work is still needed to uncover diagnostically useful genetic markers or even causative variants for equine respiratory diseases. Nonetheless, chromosomal regions associated with guttural pouch tympany, recurrent laryngeal neuropathy and RAO have been identified. The association of RAO with other hypersensitivities and with resistance to intestinal parasites requires further study. This review aims to provide an overview of the available data and current thoughts on the genetics of equine airway diseases.

Abstract
To assess the effect on exercise capacity and tolerability of resveratrol, 13 healthy, sedentary adult volunteers were enrolled in a randomized crossover study comparing resveratrol and placebo over two 4-week periods, with a 2-week time between periods when subjects received no treatment. No significant changes in exercise duration or aerobic capacity (peak oxygen uptake) were observed. Gastrointestinal side effects were more common during resveratrol treatment (77% vs. 15%, p = 0.0048). A small reduction in fasting glucose and small but statistically significant increases in liver enzymes, total cholesterol, and triglycerides were observed, although mean results remained within normal limits. There was no change in complete blood count, inflammatory markers, renal function, or other measures of liver function.

Abstract
This article reports preliminary research results on a professional development (PD) model as a mechanism for supporting absorption of the Healthy School (HS) approach into school functioning. The purpose of our study was to document the model implementation process and understand whether it influenced, or not, the accompanied actors' knowledge and practices about HS. The theoretical basis of the model and a description of its implementation, its appreciation by actors and its influence on their knowledge and confidence are presented. The research was conducted in three Quebec schools that had adopted this approach for at least 2 years. Multiple case study methodology, with pre- (T0) and post- (T1) intervention comparison, was adopted. The results disclose that the PD model implemented, which involves socio-constructivist accompaniment, has several assets that support the acquisition and application of new knowledge related to HS in order to promote its absorption within schools. Our findings indicate that PD likely reinforced the actors' knowledge and understanding as well as their confidence. The lessons drawn from the evaluation of this PD model could serve to enhance accompaniment methods implemented to promote the absorption of such initiatives in schools. Our data highlight the relevance and effectiveness of accompaniment anchored in action, calling for practice based on reflection and expert recommendations to meet the objectives of health and academic success.

Abstract
Diseases of paranasal sinuses and nasal passages in horses can be a diagnostic challenge because of the complex anatomy of the head and limitations of many diagnostic modalities. Our hypothesis was that magnetic resonance (MR) imaging would provide excellent anatomical detail and soft tissue resolution, and would be accurate in the diagnosis of diseases of the paranasal sinuses and nasal passages in horses. Fourteen horses were imaged. Inclusion criteria were lesions located to the sinuses or nasal passages that underwent MR imaging and subsequent surgical intervention and/or histopathologic examination. A low field, 0.3 tesla open magnet was used. Sequences in the standard protocol were fast spin echo T2 sagittal and transverse, spin echo T1 transverse, short-tau inversion recovery (STIR) dorsal, gradient echo 3D T1 MPR dorsal (plain and contrast enhanced), spin echo T1 fatsat (contrast enhanced). Mean scan time to complete the examination was 53 min (range 39-99 min). Lesions identified were primary or secondary sinusitis (six horses), paranasal sinus cyst (four horses), progressive ethmoid hematoma (two horses), and neoplasia (two horses). The most useful sequences were fast spin echo T2 transverse and sagittal, STIR dorsal and FE3D MPR (survey and contrast enhanced). Fluid accumulation, mucosal thickening, presence of encapsulated contents, bone deformation, and thickening were common findings observed in MR imaging. In selected horses, magnetic resonance imaging is a useful tool in diagnosing lesions of the paranasal sinuses and nasal passages.

Abstract
BACKGROUND Many patients with chronic obstructive pulmonary disease continue to experience significant functional limitation despite the use of both long-acting anticholinergic and beta-agonist inhalers. Theophylline is a widely available medication which may further improve lung function and exercise performance. Previous studies evaluating the effects of theophylline on exercise capacity in chronic obstructive pulmonary disease (COPD) have demonstrated heterogeneous results. METHODS We performed a randomized placebo-controlled double-blind pilot study assessing the effects of theophylline on constant load exercise duration and lung function, involving 24 COPD patients already treated with long-acting inhaled beta-agonist and long-acting anti-cholinergic bronchodilator therapy. RESULTS Analyzable data was available in 10 of 12 subjects in the treatment arm and 11 of 12 subjects in the control arm. Theophylline was associated with a 26.1% (95% confidence interval [CI]: -17.3-69.5) improvement in exercise duration compared to placebo. Four of 10 treated patients demonstrated an improvement in exercise duration exceeding the minimum clinically important difference of 33%, compared to 1 of 11 controls (P = 0.15). Furthermore, peak ventilation was reduced by 11.1%, (95% CI: 0.77-21.5) which may suggest improvements in gas exchange. There were no significant observed differences in resting lung function nor measures of dyspnea between the two treatment groups. CONCLUSIONS Our study demonstrated a trend, but not a statistically significant improvement in exercise duration and a reduction in peak ventilation with theophylline. Based on the observed mean differences and standard deviations in this pilot study, a randomized controlled trial would require 45 subjects in each arm to detect a significant change in exercise duration.

Abstract
The purpose of this study was to examine the possibility of improving the assessment protocol of dysphagia and show the interest of adding a self-assessment evaluation scale to the traditional functional assessment of the swallowing process. We have a comparison of the assessment of 30 dysphagic patients with two different scales (DHI and EAT-10). Results show that the self-evaluation scales selected led to quantitative data comparable to the objective results of the COLP-FR-G functional assessment tool. We may therefore conclude that the patients' own feelings do not differ from the results of the clinical dysphagia severity assessment. Results also highlight that both scales provide similar information in terms of content and also reflect the evolution of objective data. The EAT-10 scale, by its simplicity and limited number of questions, could be proposed as a screening test in neurological patients and geriatric population, where the DHI scale, with its three subdomains (physical, functional and emotional), would be a complementary tool for the functional swallowing evaluation. Indeed, in order to evaluate dysphagia, the association of DHI, EAT-10 and COLP-FR-G offers several advantages. This protocol is convenient and rapid to administrate, it takes the diversity of etiologies into account and its score is easy to transmit to the patients' medical practitioners. Consequently, its use in the assessment of swallowing functions should be encouraged as a consistent part of the clinical practice.

Abstract
In this study, plasma lipids, lipoproteins and markers of oxidant/antioxidant status were investigated in young (n = 45) and older (n = 40) obese men and compared to those in young (n = 65) and older (n = 55) normal weight controls. The purpose was to determine whether obesity exacerbates or not lipid, lipoprotein abnormalities and oxidative stress in older men. Our findings showed that all obese patients had increased plasma triglyceride, cholesterol, LDL-cholesterol, -triglyceride and HDL-triglyceride levels concentrations compared to controls (P < 0.01). However, the younger obese men had relatively larger and accentuated changes in plasma lipids and lipoproteins than the older patients. Additionally, total antioxidant capacity (ORAC), vitamins C and E were lower while hydroperoxides and carbonyl proteins were higher in young and older obese patients compared to their respective controls (P < 0.001). Erythrocyte antioxidant SOD and catalase activities were enhanced in obese young patients, but reduced in obese older men. Glutathione peroxidase activity was low in obesity irrespective of age. In multiple regression analysis, BMI significantly predicted total cholesterol, LDL-C, LDL-TG and HDL-TG (P < 0.0001). These relationships were not modified by age. BMI alone was a not a significant predictor for ORAC, vitamins C, E, catalase and Glutathione peroxidase. However, the interaction BMI-age significantly predicted these parameters and explained 28-45% of their changes. BMI was a significant predictor of SOD, carbonyl proteins and hydroperoxides. This effect became more significant (P < 0.0001) and worsened with BMI-age interaction. In conclusion, lipoprotein metabolism and oxidant/antioxidant status are altered in obesity irrespective of age. However, obesity-related lipid and lipoprotein alterations were attenuated while oxidative stress was aggravated in older adults.

Abstract
ObjectiveTo explore tolerability and treatment response in adult patients with recently diagnosed (≤5 years) and chronic (>5 years) schizophrenia treated with flexible doses of paliperidone ER.MethodsInternational prospective open-label 6-month study. Endpoints were the Positive and Negative Syndrome Scale (PANSS), patient functioning and treatment-emergent adverse events (TEAEs).ResultsOf 713 recently diagnosed patients, most were male (60.9%), mean age was 33.6 ± 11.2 years and mean time since diagnosis was 2.3 ± 1.7 years. Chronic patients (n = 1003) were predominantly male (59.2%) with a mean age of 43.8 ± 11.4 and mean time since diagnosis of 15.6 ± 9.2 years. 70.4% and 71.7% of patients completed the study, respectively. Mean mode doses of paliperidone ER were similar between recently diagnosed and chronic patients (7.0 ± 2.9 mg/day and 7.2 ± 2.9 mg/day). 63.1% of recently diagnosed and 60.8% of chronic patients switching due to lack of efficacy with their previous antipsychotic had a ≥20% improvement in PANSS total score at endpoint, and improvement with other switching reasons was consistently numerically higher in recently diagnosed patients. The rate of patients with mild or no functional impairment increased from 17.7% to 39.8% in recently diagnosed and from 14.4% to 32.9% in chronic patients. TEAEs reported in ≥5% were insomnia (10.7% and 8.1%), anxiety (8.6% and 6.0%) and somnolence (5.8% and 3.4%), respectively.ConclusionThese data suggest that both recently diagnosed and chronic patients previously unsuccessfully treated with other oral antipsychotics may benefit from paliperidone ER, with a tendency for recently diagnosed patients showing some higher treatment response in psychotic symptoms and patient functioning.

Abstract
PRIMARY OBJECTIVE To assess a rehabilitation programme of working memory. RESEARCH DESIGN Single case multiple-baseline-across-behaviour design in a patient with chronic stroke suffering from a specific impairment of working memory. METHODS Rehabilitation included training of storage and processing components of verbal working memory. Outcome was assessed with specific working memory tests, non-specific tasks requiring working memory, non-target tasks not requiring working memory and questionnaires addressing daily-life functioning. This assessment was performed twice before the experimental therapy and once after. RESULTS Cognitive measures were stable before therapy. A statistically significant improvement was found for target measures and for daily-life skills. In contrast, no change was found on non-target tasks. CONCLUSION Improvement was not apparently related to spontaneous recovery, since performance was stable before therapy. This study suggests that specific cognitive training may improve working memory in patients with brain injury.
