Abstract
Male reproduction is one of the primary health endpoints identified in rodent studies for some phthalates, such as DEHP (Bis(2-ethylhexyl) phthalate), DBP (Dibutyl phthalate), and BBP (Benzyl butyl phthalate). The reduction in testosterone level was used as an intermediate key event for grouping some phthalates and to establish a reference point for risk assessment. Phthalates, and specifically DEHP, are one of the chemicals for which the greatest number of non-monotonic dose responses (NMDRs) are observed. These NMDRs cover different endpoints and situations, often including testosterone levels. The presence of NMDR has been the subject of some debate within the area of chemical risk assessment, which is traditionally anchored around driving health-based guidance values for apical endpoints that typically follow a clear monotonic dose-response. The consequence of NMDR for chemical risk assessment has recently received considerable attention amongst regulatory agencies, which confirmed its relevance particularly for receptor-mediated effects. The present review explores the relationship between DEHP exposure and testosterone levels, investigating the biological plausibility of the observed NMDRs. The Adverse Outcome Pathway (AOP) concept is applied to integrate NMDRs into Key Event Relationships (KERs) for exploring a mechanistic understanding of initial key events and possibly associated reproductive and non-reproductive adverse outcomes.

Abstract
Abstract
Background
Anemia is common in patients with symptomatic coronary artery disease. Observational studies investigated blood transfusion threshold in symptomatic coronary artery disease but results were conflicting. Meta-analyses evaluating transfusion threshold utilized data mainly from observational trials but no meta-analysis, to our knowledge, used data solely from randomized clinical trials.
Objective
The goal of our study is to evaluate efficacy and safety outcomes in anemic patients presenting with symptomatic coronary artery disease using pooled data from randomized clinical trials.
Methods
We queried Medline, Embase and Cochrane data bases for randomized clinical trials comparing restrictive blood transfusion (defined as transfusion when hemoglobin is less than 8 gm/dl) vs liberal blood transfusion (transfusion when hemoglobin is less than 10 gm/dl) in patients presenting with symptomatic artery disease or acute coronary syndrome. We identified 3 randomized controlled trials; MINT, CRIT and REALITY trials. Data were pooled from 3 trials. Efficacy outcomes evaluated were all-cause mortality and New or recurrent myocardial infarction. Safety outcomes were congestive heart failure at 30-day follow up.
Results
A total of 820 patients were included in our meta-analysis; 420 patients in restrictive blood transfusion protocol and 400 in liberal blood transfusion protocol
There was no difference between two groups at 30-day follow up in all identified outcomes (all-cause mortality, new or recurrent myocardial infarction, and Congestive heart failure).
55 patients died (22/420 in restrictive group and 33/400 in liberal group). Risk ratio of all-cause mortality in restrictive group was 0.63 [95% CI (0.38–1.07), P=0.09, I2=30%].
15/420 in restrictive group and 16/400 in liberal group had new or recurrent myocardial infarction. Risk ratio of myocardial infarction in restrictive group was 0.91 [95% CI (0.46–1.80), P=0.78, I2=0%].
20/420 patients in restrictive group and 24/400 in liberal group had congestive heart failure with risk ratio of 0.80 [95% CI (0.19–3.37), P=0.30, I2=76%] in restrictive group.
Conclusion
Our meta-analysis showed similar outcomes between restrictive and liberal transfusion policies in patients presenting with symptomatic coronary artery disease of acute myocardial infarction. Our findings are consistent with available data about restricting transfusion in general population. Restricting blood transfusion might be cost-effective. Further studies are warranted to evaluate long term safety and efficacy of such approach.

Abstract
Background:Solitary plasmocytoma is a rare tumour that represents around 2 to 5% of all plasma cell dyscrasias. It normally affects soft tissu but rarely the bone. Diagnosis is based on histology, the absence of bone marrow involvement.Objectives:To drag attention to think of solitary plasmocytoma of bone when dealing with a vertebral fracture in the absence of the CRAB criteria of multiple myeloma.Methods:We report a rare case of a vertebral fracture of the 4th lumbar vertebra (L4) revealing a solitary plasmocytoma of bone.Results:A 67-year-old female patient presented to our rheumatology department with back and left radicular pain of brutal onset, 15 days prior to her visit. Pain was severe and awakened her at nights. On examination, mobilities of the spine were unchanged but on palpation she had exquisite pain of L4. Laboratory tests showed a normal sedimentation rate of 15mm the first hour, a negative c-reactive protein, normal calcemia and kidney tests. X-rays of lumbar spine showed a vertebral fracture with a destruction over 50% of the vertebral size and cortical rupture. MRI of the spine showed the absence of other lytic lesions or other fractures or spinal cord compression and showed the total destruction oft he anterior vertebral body of L4 (Figure 1). Protein electrophoresis was in normal range and 24h urinary proteinuria was negative. Other tests rules out gynecological, thyroid, and renal neoplasms. Sternal puncture showed a rich bone marrow of normal cells without further infiltration. Bone biopsy of the detected lesion showed tumour cells made of mature plasmocytes confirming the diagnosis of solitary plasmocytoma of the bone. The patient was treated with radiation therapy. The evolution after 24 months showed a stabalised lesion and the absence of progression to multiple myeloma.Figure 1.T2 weighted MRI showing the vertebral fracture of L4Conclusion:It is important to keep in mind the diagnosis of solitary plasmocytoma of bone when facing a solitary lesion or vertebral fracture despite relatively non agressive radiological signs. It is also important to note the possible evolution to multiple myeloma and keep a hawk-eyed guard.References:[1]Masmoudi K, Elleuch E, Akrout R, et al.

Abstract
Background:The screening and treatment of latent tuberculosis infection (LTBI) is required before starting biologic therapy. Tuberculin skin test (TST) and interferon γ gamma release assay (IGRA) are the two commonly used tests.Objectives:The aim of our study was to analyze data from the Biological National Registry BINAR between 2016 and 2020 in order to compare the diagnostic value of TST and IGRA tests.Methods:We collected data of patients diagnosed with LTBI (having had a TST and/or IGRA before receiving any biotherapy) from the BINAR registry (a National Tunisian registry of patients with inflammatory rheumatic diseases under biologic therapy since less than two years from the inclusion date).Results:From a total of 298 patients included in our study, 199 patients (66.8%) were screened by TST and 159 patients were screened (53.4%) by IGRA.Thirty-four patients (11.4%) had a positive TST and 27 patients (9.1%) had a positive IGRA test.Three patients having negative TST and two having negative IGRA developed tuberculosis.There was no significant difference in our study between these two tests for LTBI diagnosis. The reactivation of tuberculosis can occur even when LTBI screening is negative using TST and IGRA tests.Conclusion:Our results show that the predictive diagnostic value for these two tests is the same. It would be more interesting to practice one of those tests prior to biotherapy.Disclosure of Interests:None declared.

Abstract
Background:Knee osteoarthritis and obesity are both major health problems. It is now admitted that the prevalence of knee osteoarthritis gets higher with obesity and that weight loss helps knee function and allows patients to avoid surgery.Objectives:The aim of this study was to study the influence of obesity on knee osteoarthritis features.Methods:A cross-sectional study was conducted in the university hospital Taher Sfar of Tunisia over a period of 6 months. Patients who had knee osteoarthritis confirmed by radiographs were included. Sociodemographic, clinical, radiological and therapeutic data were collected from medical records and visits. Obesity was defined by a body mass index (BMI) ≥30. Functional impairment was assessed by the Womac index and Lequesne index.Results:The study included 186 patients. There were 31 males and 155 femmes. The mean age was 60±10 years. The percentage of obese patients was 53,8%. The mean age was similar in both groups obese and non obese. There were more women in the obese group compared to the non obese group (p=0.0001), more patients who had diabetes mellitus and dyslipidemia (p=0.002). Non-obese patients had a shorter duration of symptoms with no statistical significance (p=0.151). Obese patients had more involvement of both knees (p<0.0001). Obesity did not have an impact on pain severity. Severity of radiological images (p=0,0001) were more frequent in obese patients. Functional impairment was similar in both groups. However, the percentage of patients having a very important functional impairment with Lequesne index was higher in obese patients (p<0.029). Obese patients also needed more physical therapy sessions (p=0.035).Conclusion:Knee osteoarthritis in obese patients is characterized with the femlae gender predominance, bilateral knee involvement, and a more severe images on radiographs. Thus the need for better control of weight and the importance of physical activity.References:[1]Coggon D, Reading I, Croft P, et al. Knee osteoarthritis and obesity.

Abstract
Background:The development of biologics for the treatment of systemic rheumatic diseases increased the risk of infections. The management of this complication deserves particular attention since it remains a major cause of morbidity and mortality.Objectives:The aim of our study was to determine infection frequency under biological treatment and consequences on the therapeutic management.Methods:Patients included in the Biological National Registry (BINAR) from 2016 to 2020. Data related to the disease, biological agents, and infections occurring under biologic disease-modifying antirheumatic drugs (bDMARDs) were collected.Results:The study included 298 patients with a mean age of 49.2 years [18-79] 175 patients with rheumatoid arthritis and 123 with spondyloarthritis (Axial Spondyloarthritis=48, Enteropathic Arthritis=41, Psoriatic Arthritis=34). Anti Tumor necrosis factor-alpha (Anti-TNF) agents were the most prescribed bDMARDs in 87.9% (n=263) of patients: Infliximab 20.4% (n=61),Etanercept 23.1%(n=69), Adalimumab 24.6%(n=74) and Certolizumab (n=79). No patients were treated with Golimumab. Tocilizumab and Rituximab were prescribed respectively in 10.4% (n=31) and 5% (n=15) of patients. Infections occured in 9 patients (3.1%) with a total of 13 infectious episodes 12 bacterial and a viral one. The site of infections was: respiratory (38%), urinary (15%), cutaneous (23%), ORL (8%), infective endocarditis (8%), and other (8%). The infectious agent was identified in only 3 patients. The outcomes were favorable in most cases except in one patient where there was a definitive interruption of bDMARDs. The patient was hospitalized for sepsis complicating a cutaneous infection with favorable outcomes under antibiotics within a week. The biological agent with higher risk of infections was Tocilizumab (p = 0.056), unlike Rituximab (p = 0.483) and Anti-TNF (p = 0.082). All patients who had an infectious episode were under corticosteroids.Conclusion:Our results confirm that bDMARDs are predisposing to infections, but data from BINAR showed that most infections were trivial with no serious outcomes. Therefore, infections should be assessed in patients under bDMARDs for an early therapeutic intervention.Disclosure of Interests:None declared.

Abstract
BACKGROUND AND AIM Heart failure is still a leading cause of mortality and morbidity. Assist devices are reserved for advanced heart failure patients with no other therapeutic options. We aim in this paper to describe the characteristics and outcome of Lebanese left ventricular assist device (LVAD) patients. RESULTS From 2010 till December 2019, 78 patients were implanted with assist devices at the Beirut cardiac Institute, 82 pumps were used. To the most recent follow up after 10 years, 26 patients died (34%). 24 patients of 35 (68%) survived more than 5 years. Seven patients only (9%) died during one month of surgery. One year mortality was 19% (15 patients). The leading cause of early mortality was infection, whereas cerebrovascular accidents CVA were the leading cause of late mortality. Pump thrombosis occurred in 12% of the cases. The most serious long term complication was haemorrhagic CVA. Only seven patients (9%) received heart transplantation, with a mean time on support prior to transplantation of 1303 ± 213 days. CONCLUSION In this manuscript we reported the characteristics and outcome of the largest population of LVAD patients in Lebanon. The survival rate was 81% at one year. These findings were comparable to the international registries except for rates of heart transplantation. More efforts should be made to encourage organ donation in Lebanon.

Abstract
Background:During the last decade, the treatment of chronic inflammatory rheumatism (CIR) has been greatly improved with the advent of biotherapy.However, the use of biological treatment can lead to a number of side effects including abnormalities in the blood count.Objectives:The aim of this study was to assess the different hematological side effects of biological treatment in patients with rheumatoid arthritis (RA) and spondyloarthitis (SA).Methods:This study included patients with RA (ACR/EULAR 2010) and SA (ASAS 2009) registred with the Tunisian Biologic National Registry (BINAR).Patients were followed and treated with biologics for 2 years of less. Clinical data relative to biological treatment, including haematological side effects, have been collected.Results:Two hundred and ninety-eight patients (178 women and 111 men) were included in the study.The mean age was 49.2 ± 14.1 years. The male/female ratio was 0.6. The mean diseases durations for RA and SA were respectively 6.7 ± 3.5 years and 6.5 ±3.6 years.Anti-TNFα agents were prescribed in 87.9% of patients (n = 263) with respectively: Infliximab (20.4%) Etanercept (23.1%), Adalimumab (24.6%) and Certolizumab (26.5%).Tocilizumab and Rituximab were prescribed in 10.4% and 5% of the patients, respectively.Blood count abnormalities were noted in 15.4 % of patients (n=46).Neutropenia was the most frequently anomaly met on the hemogram (9.1%) followed by anemia (3.4%) and thrombocytopenia (3%). Pancytopenia was found in 11.4% of patients (n=34).The median time between biological therapy initiation and the onset of hematologic manifestations was 4.8 months [1-12]. Biological treatment was interrupted in two patients.In the other cases, the biological treatment was maintained with close monitoring of blood cell count. No case of death related to these hematological disturbances has been reported.Conclusion:In our registry, hematological side effects of biological treatment were found in 15.4% of cases and were noted with a median delay of 4.8 [1-12] months after the treatment initiation. Further studies are needed to confirm our preliminary results.Disclosure of Interests:None declared

Abstract
Abstract
Introduction
The odds ratio product (ORP) is a new highly-validated electroencephalogram biomarker of sleep depth. ORP has been validated as such by several studies investigating the effect of sleep disorders, responses to sleep deprivation and traffic noise. ORP during REM sleep varies considerably among individuals. Whether ORP reflects sleep depth also in REM sleep is unknown. We hypothesized that subjects with high REM ORP are more prone to REM sleep fragmentation.
Methods
Using data from the baseline (SHHS1; N=5,537) and follow-up (SHHS2; N=2,595) visits of the Sleep Heart Health Study, we calculated and summarized ORP in 30-second intervals corresponding to manually scored sleep stage epochs. We developed a heuristic to identify REM periods, defined as sequences of REM sleep epochs separated by no more than 10 minutes of other sleep stages or wake epochs. Using general linear models adjusted by age, sex, body mass index, race and ethnicity, we evaluated the relationship between REM ORP and total REM duration, number of awakening episodes per REM period and arousal index during REM sleep.
Results
Higher REM ORP was correlated with shorter total REM duration (ρ SHHS1=-0.12; p < 0.001, ρ SHHS2=-0.07; p < 0.001), more awakening episodes (ρ SHHS1=0.26; p<0.001, ρ SHHS2=0.30; p < 0.001) and higher arousal index (ρ SHHS1=0.18; p < 0.001, ρ SHHS2=0.16; p < < 0.001) during identified REM periods. In adjusted analyses, one-unit increase in REM ORP was associated, on average, with a 7 minute decrease in total REM duration (β=-7.10; p < 0.001), 1 more awakening episode per REM period (β=1.29; p < 0.001) and an increase of 6 arousals/hour (β=6.16; p < 0.001) during REM sleep periods.
Conclusion
We found that higher REM ORP was associated with shorter REM periods, higher proportion of awake during REM periods and higher REM arousal index. Although small, these differences suggest that ORP is consistent with the concept of sleep depth also during REM sleep.

Abstract
Abstract
Introduction
Upper airway stimulation (UAS) is a surgical method of treating obstructive sleep apnea (OSA). UAS involves an implantable neuro-stimulator that stimulates the hypoglossal nerve to protrude the tongue during sleep. OSA fails to improve in 22% of patients who receive UAS as defined by a > 50% reduction in Apnea-Hypopnea Index (AHI) and an AHI <20 events/hour. Light sleep may predict UAS failure in that it may limit the stimulus strength that can be applied. The odds ratio product (ORP) is a novel polysomnographic (PSG) metric of sleep depth. We hypothesized that ORP values prior to surgery will be higher (lighter sleep) in non-responders. Having markers that predict surgical success can help reduce unnecessary surgeries.
Methods
This is a retrospective cohort study of 126 patients (83 responders vs. 43 non-responders) who received UAS implantation for the treatment of OSA. PSG data was obtained from the Stimulation for Apnea Reduction (STAR) trial. Raw baseline PSG data were analyzed and ORP values calculated using Michele Sleep Scoring Software (Cerebra Medical, Winnipeg, CA). In addition, 13 PSG metrics that were considered possibly relevant to surgical outcome were calculated as an exploratory analysis. The measurements included: spindle density, spindle power, spindle frequency, alpha intrusion, Right/Left sleep depth correlation coefficient, respiratory duty cycle, respiratory flow limitation, and arousal intensity. Statistical Analysis: Comparisons between responders and non-responders used parametric t-tests for continuous data and chi-squared or Fisher’s exact tests for categorical data. Statistical significance was based on a Bonferroni-corrected p<0.00357.
Results
Differences in ORP values and other PSG metrics between responders and non-responders were not statistically significant. Of all PSG metrics only differences in spindle density approached statistical significance (Responders = 2.33 spindles/minute vs Non-Responders = 1.39 spindles/minute, p=0.00360).
Conclusion
The findings suggest that differences in sleep depth and several other sleep characteristics do not play a significant role in determining response to UAS therapy.

Abstract
Abstract
Introduction
It is well known that sleep becomes lighter towards the end of the night reflecting the reduction in homeostatic sleep pressure. We hypothesized that more adequate nocturnal sleep (i.e. sufficient quantity and quality for the individual) would result in a greater reduction in sleep depth across the night and would be reflected in decreased next-day sleep tendency.
Methods
In a secondary analysis of data from a study in which sleep depth was altered by sleep restriction combined with either placebo or gaboxadol (a delta-promoting drug) we correlated change across the night in two measures of sleep depth with next-day Multiple Sleep Latency Test (MSLT) latencies. Forty-one healthy subjects underwent 8 consecutive sleep studies; two baseline, four sleep restriction (5 hours) and two recovery nights. MSLT was performed following each baseline night and the last two restriction nights. Sleep depth in the first and last hours of NREM sleep was determined by two
methods
1) Log delta spectral power; 2) The odds-ratio-product (ORP), a recently introduced continuous measure of sleep depth. The difference between initial and final values was calculated (ΔDelta, ΔORP). Post-restriction MSLT latency was correlated with baseline MSLT latency, ΔDelta, ΔORP, log delta power and ORP in the last hour, lost total sleep time and lost REM time.
Results
ΔDelta was -0.27 ±0.13 and ΔORP was 0.17 ±0.13, both changes reflecting lightening of sleep across the night. In both univariate and multivariate analysis only baseline MSLT latency (p < 0.001) and ΔORP (p < 0.01) were significantly and positively correlated with post-restriction MSLT latency.
Conclusion
The reduction in sleep depth across the night as measured by ORP, but not by delta power, is significantly correlated with reduced objective sleepiness following sleep restriction. ΔORP may be a useful index that reflects sleep adequacy during the night.

Abstract
Abstract
Introduction
The Odds-Ratio-Product (ORP) is a highly-validated continuous index of sleep depth (range 0=deep sleep; 2.5=full wakefulness). ORP values fluctuate within this range as sleep state changes between wake and different sleep stages. In healthy non-sleep deprived adults, intra-class correlation coefficient of concurrent right vs. left ORP values (R / L coefficient) is typically >0.80. In a recent study R / L coefficient was markedly reduced in many critically-ill patients and these patients failed to be weaned from mechanical ventilation. Given the high prevalence of sleep loss in such patients we hypothesized that reduction in R/L coefficient might result from sleep loss. This retrospective EEG analysis of data from 3 independent research studies investigated if R / L coefficient decreases in pure models of sleep deprivation, restriction or noise exposure during sleep in healthy subjects.
Methods
Polysomnograms were obtained from three studies: A) 200 subjects who underwent 36 hours of total sleep deprivation; B) 21 subjects who underwent 4 consecutive nights of sleep restriction (5 hrs. / night); C) 72 subjects who were exposed to intermittent traffic noise events with maximum sound pressure levels ranging from 45–65 dB(A) for 10 consecutive nights. For study A, R / L coefficient was calculated from pre- and post-deprivation sleep studies and the two values were compared. For study B, coefficient was calculated at baseline and in each restriction night. For study C, the coefficient was calculated in each of the 10 exposure nights and the slope of the change was calculated.
Results
In study A, the coefficient decreased from 0.82±0.12 at baseline to 0.74±0.16 after sleep deprivation (p < 0.0001). In study B, the coefficient decreased from 0.83±0.11 at baseline to 0.75±0.15 on the 4th restriction night (p < 0.01). In study C, coefficient decreased at a rate of 0.003±0.001 per exposure night (p < 0.001).
Conclusion
The correlation between sleep depth in the right and left hemispheres deteriorates following sleep deprivation, restriction or noise-induced sleep fragmentation.

Abstract
Abstract
Introduction
There is currently no well-validated method for evaluating objective sleep depth/intensity. Delta power is thought to reflect sleep depth based upon limited evidence. Odds-ratio-product (ORP) is a recently introduced continuous measure of sleep depth. We compared delta spectral power (delta) and ORP as measures of sleep depth/intensity during manipulations that altered sleep depth (sleep restriction with placebo or with a delta-promoting drug). We hypothesized that ORP will provide a more robust measure of sleep depth.
Methods
This is a secondary analysis of data from a study in which forty-one healthy subjects were sleep restricted and randomized to receive placebo or gaboxadol 15mg. Participants underwent consecutive in-laboratory sleep studies on two baseline, four sleep restriction (5 hours) and two recovery nights. The relation between delta or ORP during any given 30s epoch and sleep depth, operationally defined as the probability of arousal / awakening occurring during the next 30 seconds (arousability), was assessed.
Results
Mean ORP values differed significantly among the four sleep / wake stages, but delta power did not differentiate wake, N1 and N2. The relation between ORP and arousability was linear across the entire range of ORP whereas delta power detected differences in arousability only with delta values < 300 μV2. Correlations with arousability in individual subjects were stronger with ORP (p < 0.0001). Receiver operating characteristic analysis found the ability to predict imminent arousal to be significantly greater with ORP than with delta power for all experimental conditions (p < 0.0001). The increase in sleep depth with restriction alone was detected on the second day of restriction by ORP (p < 0.01) but not by delta.
Conclusion
As compared to delta power, ORP is more discriminating among sleep stages, more sensitive to sleep restriction, and more closely associated with arousability. These observations indicate ORP better reflects sleep depth/intensity.

Abstract
INTRODUCTION Bacterial necrotizing dermis-hypodermitis and necrotizing fasciitis (BNDH-NF) are serious life-threatening soft-tissue infections. The object is to evaluate the quality of life (QOL) of patients who have been operated in our plastic surgery departement. PATIENTS AND METHODS This is a retrospective study of cases who have been treated at Nancy University Hospital between 2005 and 2014. We analyzed the perioperative data (demographic, clinical, bacteriological), the surgical data (excision, reconstruction) and the follow up data (consequences, mortality). The quality of life was assessed by the Short-Form 36 score, and the patients' satisfaction was assessed by a four-level scale. RESULTS We analyzed 23 patients with an average age of 60 years (28-84 years). The main comorbidities were diabetes (43 %) and obesity (39 %). The average number of surgical excision was about 1.9 (1-5) and the average excised body surface area was about 5 % (1-16 %). The short-term mortality was about 17 %. The mortality rate has been statistically correlated with the surgically excised body surface area (short-term 95 days: P=0.02; and long-term: P=0.003). The statistical analysis has shown a strong relative linear relationship between number of surgical excision and the physical score of QOL (P<0.001), between number of surgical excision and mental score of QOL (P=0.032), and between age and physical score of QOL (P≤0.021). The statistical analysis has also shown a strong relative linear relationship between E. coli infections and physical score of QOL (P=0.01). The percentage of patients' satisfaction in our study was evaluated at 86 %. CONCLUSION We have found that multiple surgical excisions, an advanced age of patients and E. coli infections have been associated with poor QOL. The mortality rate increased in relation with the importance of excised body surface. In spite of the gravity of these infections, our patients were satisfied of their treatment.

Abstract
The pheochromocytome is a localized tumor at the level of the medullosurrenale in 85% of the cases. The clinical presentation is very variable. Severe Heart failure presentation can be the mode of revelation in 2% of the cases. We present the case of a patient admitted for refractory cardiogenic shock correlated to pheochromocytome tumor. The difficulty of this rare clinical presentation was to confirm rapidly and in emergency this diagnosis in the same time when the patient presents a persistante and severe cardiogenic chock after finding a sub-occluded and thrombotic LAD coronary artery and which was treated by thrombectomy and coronary revascularization. The surgical treatment of this tumor is considered to be a quickly saving treatment. It allows a fast recovery of the cardiac function.

Abstract
In equine long-distance endurance competitions, nearly 40% of the starters are eliminated at a veterinary control. Excessive racing speed, the nature of the race venue and the distance covered have been identified as risk factors for elimination. The objective of the present study was to assess whether speed, venue country and the horse’s age are risk factors for elimination, on the basis of individual electronic timing datasets collected during long-distance endurance competitions. Data were obtained for 7,032 horses entered in 80 to 160 km endurance rides in four countries. For each horse and each competition, the datasets included the distance covered, age, average speed, cardiac recovery time and heart rate measured at Vet gate for each phase of the race, and the outcome of the race (i.e. qualification or elimination). For eliminated horses, the reason and phase of elimination were also recorded. An analysis of variance was used to identify and compare variability factors and differences in recorded variables in qualified vs eliminated horses. In the study population, 39% of the starters were eliminated – mostly due to lameness (64%) or metabolic reasons (15%). The eliminated horses displayed a higher speed and worse recovery during the first phases of the race (P<0.05). The mean speed was higher in events organised in the United Arab Emirates, in 2-star rides and in intermediate/mature horses; these factors were associated with slower cardiac recovery and a greater risk of elimination. Our results confirm that excessive speed is a major risk factor for elimination in endurance rides and further indicate that factors such as the venue country, the event distance and the horse’s age are also involved. With a view to increasing completion rates and reducing fatal injuries in endurance races, preventive measures should take these factors into account.

Abstract
Pancreatic cancer is one of the most lethal malignancies, with virtually all patients eventually succumbing to their disease. Mutations in p53 have been documented in >50% of pancreatic cancers. Owing to the high incidence of p53 mutations in PanIN 3 lesions and pancreatic tumors, we interrogated the comparative ability of adult pancreatic acinar and ductal cells to respond to oncogenic Kras and mutant Tp53(R172H) using Hnf1b:CreER(T2) and Mist1:CreER(T2) mice. These studies involved co-activation of a membrane-tethered GFP lineage label, allowing for direct visualization and isolation of cells undergoing Kras and mutant p53 activation. Kras activation in Mist1(+) adult acinar cells resulted in brisk PanIN formation, whereas no evidence of pancreatic neoplasia was observed for up to 6 months following Kras activation in Hnf1beta(+) adult ductal cells. In contrast to the lack of response to oncogenic Kras alone, simultaneous activation of Kras and mutant p53 in adult ductal epithelium generated invasive PDAC in 75% of mice as early as 2.5 months after tamoxifen administration. These data demonstrate that pancreatic ductal cells, whereas exhibiting relative resistance to oncogenic Kras alone, can serve as an effective cell of origin for pancreatic ductal adenocarcinoma in the setting of gain-of-function mutations in p53.

Abstract
This study aimed to explore the effects of "touch-rugby" training on the cardiovascular autonomic control in sedentary subjects. 22 adults (30-64 years old) were included in this study. Before (pre-test) and after (post-test) the period of training, cardio-respiratory recordings were achieved at rest and during a graded maximal exercise on a treadmill. The Smoothed-Pseudo-Wigner-Ville Distribution provided instantaneous time frequency components of RR intervals and systolic blood pressure variability in low- and high-frequency bands. The baroreflex sensitivity was assessed in low-frequency and high-frequency bands. Between pre-test and post-test, resting heart rate (74±10 vs. 69±12 beats.min(-1), p<0.05) and systolic blood pressure (118±19 vs. 103±22 mm Hg, p<0.01) decreased. Root mean square of successive differences (34.6±30.1 vs. 47.6±34.8 ms, p<0.001), high-frequency RR variability (590±288 vs. 1262±767 ms², p<0.001) increased whereas low-frequency/high-frequency ratio decreased (3.5±3.4 vs. 1.5±0.9, p<0.05). The high-frequency baroreflex sensitivity increased (13.4±10.1 vs. 26.0±20.9 ms.mmHg(-1), p<0.05). Playing touch rugby with one session weekly over 3 months modified the cardiovascular autonomic control of sedentary subjects. A decrease in the sympathetic tone combined with both an increase in the vagal tone and a decrease in systolic blood pressure at rest were observed. Therefore, such training appears to be beneficial to cardiac health.
