Abstract
Disease emergence represents a global threat to public health, economy and biological conservation. Most emerging zoonotic diseases have an animal origin, most commonly from wildlife. To prevent their spread and to support the implementation of control measures, disease surveillance and reporting systems are needed, and due to globalisation, these activities should be carried out at the global level. To define the main gaps affecting the performance of wildlife health surveillance and reporting systems globally, the authors analysed data from a questionnaire sent to National Focal Points of the World Organisation for Animal Health that inquired on structure and limits of wildlife surveillance and reporting systems in their territories. Responses from 103 Members, covering all areas of the globe, revealed that 54.4% have a wildlife disease surveillance programme and 66% have implemented a strategy to manage disease spread. The lack of dedicated budget affected the possibility of outbreak investigations, sample collection and diagnostic testing. Although most Members maintain records relating to wildlife mortality or morbidity events in centralised databases, data analysis and disease risk assessment are reported as priority needs. The authors' evaluation of surveillance capacity found an overall low level, with marked variability among Members that was not restricted to a specific geographical area. Increased wildlife disease surveillance globally would help in understanding and managing risks to animal and public health. Moreover, consideration of the influence of socio-economic, cultural and biodiversity aspects could improve disease surveillance under a One Health approach.

Abstract
PURPOSE Hyponatremia is the most frequent electrolytic disorder in clinical practice. In addition to neurological symptoms, hyponatremia, even when mild/moderate and chronic, has been related to other manifestations, such as bone demineralization and increased risk of fractures. To better elucidate tissue alterations associated with reduced serum sodium concentration [Na+], we developed an in vivo model of hyponatremia secondary to the Syndrome of Inappropriate Antidiuresis. METHODS AND RESULTS Hyponatremia was induced in Foxn1nu/nu mice by subcutaneous infusion of the vasopressin analog 1-deamino [8-D-arginine] vasopressin (dDAVP) for 14 days via osmotic mini-pumps. Mice in the control group were infused with isotonic saline solution. Serum [Na+] progressively decreased, with a nadir of 123.4 ± 2.3 mEq/L (mean ± SD, dDAVP 0.3 ng/h) and 111.6 ± 4.7 mEq/L (mean ± SD, dDAVP 0.5 ng/h). Evident signs of liver steatofibrosis were observed at histology in hyponatremic mice. Accordingly, the expression of proteins involved in lipid metabolism (SREBP-1, PPARα and PPARγ) and in myofibroblast formation (αSMA and CTGF) significantly increased. Furthermore, heme oxygenase 1 expression was up-regulated in Kupffer and hepatic stellate cells in the liver of hyponatremic mice. Testis alterations were also observed. In particular, the thickness of the seminiferous epithelium appeared reduced. The expression levels of PCNA and PTMA, which are involved in DNA replication and germ cells maturation, were markedly reduced in the testis of hyponatremic mice. CONCLUSION Overall, these findings shed new light on the possible consequences of chronic hyponatremia and prompt a more thorough evaluation of hyponatremic patients.

Abstract
Colovesical fistula (CVF) is an abnormal connection between the colon and the urinary bladder. Faecaluria, reported in 40–70% of cases, is virtually pathognomonic for CVF. During the 5th day of recovery in an 84 years old subject, the passage of cloudy, malodorous urine with visible debris was observed. According to the pathognomonic character of faecaluria, the sample was signed to the laboratory for biochemical and microbiological investigation, able to define the type and origin of materials. Following clinical requirements, both biochemical pathways and instrumental procedures able to confirm or exclude the presence of faecal components in urine were considered. No biochemical compound or component addressing faecal compounds in urine results available between laboratory tests. The brown powder component of the pellet was identified as Keratin, with 90% overlapping with the reference spectrum of the compound. FT-IR analysis on urine pellet can be proposed as a simple, non-invasive, and fast method to improve the diagnostic course of CVF.

Abstract
Introduction Amenorrhea is one of the most frequent and serious consequences of Anorexia Nervosa (AN). Resumption of menses (ROM) is considered an important goal and is associated with a better outcome. Objectives To investigate the role of age, Body Mass Index (BMI), diagnostic subtype (restrictive vs binge-purging), history of childhood abuse, duration of illness, psychopathology and sex hormones on ROM in AN. Methods 52 patients with AN and amenorrhea were enrolled at the start of treatment. Clinical parameters of interest were collected, and questionnaires were administered for the assessment of general (SCL-90-R) and specific (EDE-Q) psychopathology. Blood samples were taken to assess FSH, LH and estradiol levels. All patients were monitored regularly through psychiatric checkups until ROM, for up to four years. Results A total of 30 (57.7%) subjects recovered their menstrual cycle in the follow-up period (mean time: 18.7 ± 14.8 months). Recovery was more frequent in the binge-purging subtype than in the restrictive subtype (82.4% vs 48.6%, p=0.019), and was significantly associated with diagnostic crossover (odds ratio=10.0, p=0.032). Multivariate Cox regression showed an increased likelihood of menstrual recovery for binge-purging subtype (p=0.005) and for those reporting a history of childhood abuse (p=0.025). Early ROM was also associated with baseline SCL-90-R scores (p=0.002) and FSH (p=0.011), while a longer duration of illness (p=0.003) and EDE-Q scores (p=0.009) predicted a later recovery.![]() Conclusions This study highlights the role of duration of illness, childhood abuse history and psychopathological characteristics in subjects with AN at the start of treatment in predicting ROM. Disclosure No significant relationships.

Abstract
The reliance on multiple hosts to survive is what makes the management and control of multi-host infectious agents challenging. Sarcoptes scabiei causes sarcoptic mange in a wide range of mammal species with ungulates being an important host. Little is known about the role different ungulates play in sustaining endemic transmission of the disease and no study has yet to describe the long-term multi-host sarcoptic infestation dynamics in free-ranging wildlife. Here, we explore 24 years of sarcoptic mange infestation data for two Mediterranean ungulate species, red deer and Iberian ibex, living in the Sierras de Cazorla, Segura y Las Villas Natural Park of southern Spain. The temporal analysis showed a clear seasonal pattern of infestation in both ungulates with a peak in early spring and a decline throughout the summer. The spatial analysis, however, showed that caprinae rather than cervidae is the most competent host for sarcoptic mange spreading and persistence. Considering that few studies have described the spatio-temporal pattern of mange outbreaks for long periods of time, the information reported in this work aims to improve our understanding of sarcoptic mange epizootic in wild ruminant populations.

Abstract
INTRODUCTION Recent automated hematology analyzers (HAs) can identify and report nucleated red blood cells (NRBC) count as a separate population out of white blood cells (WBC). The aim of this study was to investigate the analytical performances of NRBC enumeration on five top of the range HAs. METHODS We evaluated the within-run and between-day precision, limit of blank (LoB), limit of detection (LoD), and limit of quantitation (LoQ) of XE-2100 and XN-module (Sysmex), ADVIA 2120i (Siemens), BC-6800 (Mindray), and UniCel DxH 800 (Beckman Coulter). Automated NRBC counts were also compared with optical microscopy (OM). RESULTS The limits of detection for NRBC of the BC-6800, XN-module, XE-2100, UniCel DxH 800, and ADVIA 2120i are 0.035×109 /L, 0.019×109 /L, 0.067×109 /L, 0.038×109 /L, and 0.167×109 /L, respectively. Our data indicated excellent performance in terms of precision. The agreement with OM was excellent for BC-6800, XN-module, and XE-2100 (Bias 0.023, 0.019, and 0.033×109 /L, respectively). ADVIA 2120i displayed a significant constant error and UniCel DxH 800 both proportional and small constant error. CONCLUSION Regards to NRBC counting, the performances shown by BC-6800, XN-module, and XE-2100 are excellent also a low count, ADVIA 2120i and UniCel DxH 800 need to be improved.

Abstract
INTRODUCTION Cellular analysis in cerebrospinal fluid (CSF) provides important diagnostic information in many pathological settings. The aim of this two-site study was to evaluate the Sysmex XN Body Fluid mode (XN-BF) for cell analysis of CSF compared to light microscopy (LM). METHODS Two hundred and seven consecutive CSF samples were analyzed in parallel with XN-BF and LM. The study also included the estimation of the limit of blank (LoB), limit of detection (LoD), limit of quantitation (LoQ), carry-over and linearity of XN-BF module. RESULTS LoQ of white blood cells (WBC) was 3×106 cells/L; linearity was good and carry-over negligible. XN-BF parameters were compared to LM for the following cell classes: total cells, WBC, polymorphonuclear (PMN), and mononuclear (MN) cells. The bias ranged from 1.3 to 15.2×106 cells/L. The receiver operating characteristics curve analysis for WBC showed an area under the curve of 0.98, and the global diagnostic agreement was 95% at a cutoff of 5×106 cells/L. CONCLUSIONS XN-BF provides rapid and accurate counts in clinically relevant ranges of CSF values, thus providing a valuable alternative to conventional LM analysis. However, microscopic review remains advisable in samples with abnormal cell counts or high fluorescent (HF-BF) cell parameter exceeding 5×106 cells/L.

Abstract
Fetal Heart Rate (FHR) monitoring represents a powerful tool for checking the arousal of pathological fetal conditions during pregnancy. This paper proposes a multivariate approach for the discrimination of Normal and Intra Uterine Growth Restricted (IUGR) fetuses based on a small set of parameters computed on the FHR signal. We collected FHR recordings in a population of 120 fetuses (60 normals and 60 IUGRs) at approximately the same gestational week through a standard CTG non-stress test. A set of 8 linear and non-linear indices were selected and computed on each recording, on the basis of their "stand-alone" discriminative properties, demonstrated in previous studies. By using the Orange® data mining suite we checked various multivariate discrimination models. The results show that a Logistic Regression performed on a limited set of only 4 parameters can reach 92.5% accuracy in the correct identification of fetuses, with 93% sensitivity and 91.5% specificity.

Abstract
Despite the availability of national and international guidelines, adequate postoperative pain (POP) management is still a challenge in Italy. One of the potential reasons for the high incidence of surgical patients complaining moderate to severe pain is the difficult application of the currently recommended analgesic techniques in clinical practice. In particular, morphine, the most commonly used systemic opioid in the POP treatment, has some unfavorable pharmacodynamic and pharmacokinetic characteristics for POP management, suggesting a potential relevant improvement by using different opioids. Many of sufentanil properties make it particularly suitable for POP control: a high affinity for the µ opioid receptor, the highest therapeutic index compared to any other opioid used in clinical practice and the absence of clinically relevant active metabolites. The elevated potency, together with the high lipophilicity of sufentanil, allow the preparation of a nanotablet, 3 mm of diameter and 0.75 mm of thickness, containing 15 µg of active drug. The sublingual route allows a longer time of drug plasmatic permanence in comparison to IV route, overcoming the need for continuous dosing. The patient-controlled system, considered in the present review, is preprogrammed to deliver one sublingual tablet of sufentanil with a 20-minute lockout period with a radiofrequency identification thumb tag allowing only the patient to activate the on demand button. Phase II and III studies have assessed the efficacy of this system in POP management, showing that it was considered more satisfactory than the IV PCA morphine system by both patients and nurses. The introduction of this simple and innovative system of patient-controlled analgesic administration could represent an opportunity for Italy to update the current practice in POP management.

Abstract
Arterial blood pressure (ABP) is an important vital sign of the cardiovascular system. As with other physiological signals, its measurement can be corrupted by different sources of noise, interference, and artifact. Here, we present an algorithm for the quantification of signal quality and for the reconstruction of the ABP waveform in noise-corrupted segments of the measurement. The algorithm quantifies the quality of the ABP signal on a beat-by-beat basis by computing the normalized mean of successive differences of the ABP amplitude over each beat. In segments of poor signal quality, the ABP wavelets are then reconstructed on the basis of the expected cycle duration and envelope information derived from neighboring ABP wavelet segments. The algorithm was tested on two datasets of ABP waveform signals containing both invasive radial artery ABP and noninvasive ABP waveforms. Our results show that the approach is efficient in identifying the noisy segments (accuracy, sensitivity and specificity over 95%) and reliable in reconstructing beats that were artificially corrupted.

Abstract
BACKGROUND This study aims at investigating the effect of a single pre-operative oral administration of morphine sulphate (Oramorph®) on pain after laparoscopic cholecystectomy (LC). METHODS Forty-one ASA I-III patients, aged 18-65 years, undergoing LC were randomly, double-blindly allocated to treatment (N.=20, 30mg Oramorph®, group M) or placebo (N.=21, group P). General anesthesia was maintained with propofol and remifentanil. All patients received ketamine 0.2 mg/kg iv at induction, intraoperative ketorolac 30mg iv and tramadol postoperatively (iv PCA: bolus 50 mg, lock-out 30 min, max 100 mg/4 hours). Numerical rating scale for pain (NRS), White's fast track and PADSS scores, tramadol consumption and adverse events were recorded for the first 24h. All patients underwent State Trait Anxiety Inventory (STAI) and Mini Mental State Examination (MMSE). RESULTS Anthropometric characteristics, MMSE, STAI, ASA status, NRS rest, White's and PADDS scores, PONV incidence were similar. Group M showed significantly lower NRS on movement during the first 3 hours after awakening. Cumulative tramadol consumption was lower in group M than in group P (185±142 mg versus 263±199 mg, P=0.199). CONCLUSION Within a multimodal approach, a single preoperative oral administration of 30 mg of morphine sulphate in patients undergoing LC did not improve pain at rest, but improved NRS on movement during the first 3 hours after awakening. Group P required a higher mean dose of tramadol compared to Group M, although not significantly. The safety profile of Oramorph® allowed fast extubation and awakening times as well as prompt home discharge within 6 hours from surgery.

Abstract
Twin pregnancies carry an inherently higher risk than singleton pregnancies due to the increased chances of uterine growth restriction. It is thus desirable to monitor the wellbeing of the fetuses during gestation to detect potentially harmful conditions. The detection of fetal heart rate from the maternal abdominal ECG represents one possible approach for noninvasive and continuous fetal monitoring. Here, we propose a new algorithm for the extraction of twin fetal heart rate signals from maternal abdominal ECG recordings. The algorithm detects the fetal QRS complexes and converts the QRS onset series into a binary signal that is then recursively scanned to separate the contributions from the two fetuses. The algorithm was tested on synthetic singleton and twin abdominal recordings. It achieved an average sensitivity and accuracy for QRS complex detection of 97.5% and 93.6%, respectively.

Abstract
Fetal heart rate monitoring is fundamental to infer information about fetal health state during pregnancy. The cardiotocography (CTG) is the most common antepartum monitoring technique. Abdominal ECG recording represents the most valuable alternative to cardiotocography, as it allows passive, non invasive and long term fetal monitoring. Unluckily fetal ECG has low SNR and needs to be extracted from abdominal recordings using ad hoc algorithms. This work describes a prototype of a wearable fetal ECG electrocardiograph. The system has flat band frequency response between 1-60 Hz and guarantees good signal quality. It was tested on pregnant women between the 30(th) and 34(th) gestational week. Several electrodes configurations were tested, in order to identify the best solution. Implementation of a simple algorithm for FECG extraction permitted the reliable detection of maternal and fetal QRS complexes. The system will allow continuative and deep screening of fetal heart rate, introducing the possibility of home fetal monitoring.

Abstract
The aim of the present article was to verify the Chronic Obstructive Pulmonary Disease (COPD) prevalence in a cohort of quarry workers who belong to the Apricena Marble District. We studied 70 workers. They received a questionnaire about the disease and confounding factors. The spirometry showed that the FEV1 was normal in 95% of workers, instead 5% showed values lower than former (Average: 73%). TNF alpha and IL-1 Beta in Exhaled breath condensate (EBC) were lower than the method limit in all workers. Our cohort is limited, but we could retain that the lung disease is not present in workers taken into consideration. Our results are in according to Rushton who demonstrated that only a prolonged occupation, higher than thirty years, is able to induce lung disease.

Abstract
BACKGROUND The aim of this study was to evaluate the efficacy of tramadol as an adjuvant to the local anaesthetic solution in patients undergoing shoulder arthroscopy for rotator cuff tear after middle interscalene block (MIB). METHODS We enrolled 120 patients (ASA I-II), scheduled for arthroscopic surgery for rotator cuff tear. The patients were sedated with midazolam 0.02 mg/kg and haloperidol 2 mg i.v. before performing MIB. All subjects underwent a MIB with 0.4 mL/kg of 0.5% levobupivacaine. After computerized randomization, all patients were allocated in 1 of 3 groups, each including 40 subjects. Group Placebo (Group P) received 0.4 mL/kg of 0.5% levobupivacaine plus isotonic sodium chloride for MIB and isotonic sodium chloride i.m. Group "Perineural Tramadol" (Group TPN) received 0.4 ml/Kg of 0.5% levobupivacaine plus 1.5 mg/kg of tramadol perineurally and isotonic sodium chloride i.m. Group "Intramuscular Tramadol" (Group TIM) received 0.4 ml/Kg of 0.5% levobupivacaine plus isotonic sodium chloride perineurally and 1.5 mg/kg of tramadol i.m. RESULTS The MIB onset times were not statistically different in the three groups. The duration of analgesia was significantly longer in Groups TPN and TIM, where tramadol was administered, either i.m. or perineurally, compared with the placebo group. A significant statistical difference was found in the duration of analgesia between the group TPN and TIM. CONCLUSION The addition of tramadol to the local anaesthetic solution administered for MIB provided a longer duration of analgesia compared with placebo and i.m tramadol administration in patients undergoing arthroscopic surgery for rotator cuff tear.

Abstract
The indications for continuous nerve blocks for the perioperative pain management in hospitalized and ambulatory patients have extended well beyond orthopaedics. These techniques are not only used to control pain in patients undergoing major upper and lower extremity surgery, but also to provide perioperative analgesia in patients undergoing abdominal, plastic, urological, gynaecological, thoracic, and trauma surgeries. Infusion regimens of local anaesthetics and supplements must take into consideration the condition of the patient before and after surgery, the nature and intensity of the surgical stress associated with the surgery, and the possible need for immediate functional recovery. Continuous nerve blocks have proved safe and effective in reducing opioid consumption and related side-effects, accelerating recovery, and in many patients reducing the length of hospital stay. Continuous nerve blocks provide a safer alternative to epidural analgesia in patients receiving thromboprophylaxis, especially with low molecular-weight heparin.

Abstract
In the last decade new ideas were born about the temporal and spatial dynamics of intercellular calcium waves in astrocytes. In this paper we introduce a new approach to analyze the ways in which astrocytes communicate in cultures. We present a method to describe the spatial propagation of Ca(2+) waves in vitro and a technique to compare the activity of different cells in vivo and in vitro under different stimulation conditions. The proposed method resulted to be an interesting way to distinguish different astrocyte clusters, which can be related to the communication characteristics in the network.

Abstract
AIM The aim of this article was to test the hypothesis that the posterior psoas compartment approach to the lumbar plexus help to achieve better blockade of the lateral femoral cutaneous and obturator nerves than the classic anterior 3-in-1 femoral nerve block. METHODS Thirty-six patients who were undergoing anterior cruciate ligament repair were randomly allocated to receive a femoral nerve block using either an anterior 3-in-1 femoral block (group Femoral, N=18) or a posterior psoas compartment approach (group Psoas, N=18) using 30 mL of 1.5% mepivacaine. Successful nerve block was defined as a complete loss of pinprick sensation in the region that is supplied by the lateral femoral cutaneous nerve along with adequate motor block of the obturator nerve 30 minutes after injection. The degree of motor block of the obturator nerve was measured using adduction strength with a mercury sphygmomanometer as previously described by Lang. RESULTS Thirty minutes after the completion of the block, sensory block of the lateral femoral cutaneous nerve was observed in 14 patients (78%) from the Psoas group and in 3 patients (17%) from the Femoral group (P=0.001). Thirty minutes after the completion of the block, a 119+/-40 mmHg decrease was found in Psoas group, in contrast to the 25+/-22 mmHg decrease found in the Femoral group (P<0.0005). CONCLUSIONS The posterior psoas compartment approach provides a more reliable block of the lateral femoral cutaneous and obturator nerves than the anterior 3-in-1 approach.

Abstract
BACKGROUND The question of whether the dose, concentration or volume of a local anesthetic solution is the relevant determinant of the spread and quality of post-operative epidural analgesia is still open. In this prospective, randomized, double-blind study, we compared the effects of a large volume-low concentration with a small-volume-high-concentration lumbar epidural infusion of levobupivacaine. METHODS Seventy patients scheduled for total hip replacement were enrolled. After surgery, patients were randomly allocated to receive a continuous epidural infusion of levobupivacaine (10.5 mg/h) using either 0.125% levobupivacaine infused at 8.4 ml/h (low concentration group, n=35) or 0.75% levobupivacaine infused at 1.4 ml/h (high concentration group, n=35). We blindly recorded the degree of pain relief at rest and during movement every 8 h for the first two post-operative days, as well as hip flexion, motor block, rescue analgesic consumption and adverse events. RESULTS No difference in pain relief was observed between groups as estimated with the areas under the curve of the verbal Numerical Rating Scale for pain over time, both at rest and during movement. Similarly, there was no difference between groups in hip flexion degree, motor blockade and hemodynamic stability. CONCLUSIONS Continuous lumbar epidural infusion of 0.75% levobupivacaine was as effective as continuous lumbar epidural infusion of 0.125% levobupivacaine, when administered at the same hourly dose of 10.5 mg, in achieving adequate analgesia both at rest and during movement, without differences in the incidence of hypotension and motor blockade.

Abstract
Recent epidemiological features of the zoonotic dermatophyte Trichophyton verrucosum were investigated in 294 calves from 20 farms located in Central Italy. By the combination of microscopic examinations and fungal cultures, the total prevalence rate of T. verrucosum infection was found to be high, with 87.7% of samples yielding positive results and 100% of farms being infected. Farm to farm prevalence of infection varied from 25% to 100% of the examined calves. Prevalence rates were higher in females than males (91.6% versus 84%), in >3-< or =6 than >6-< or =9 month old calves (89.8% versus 85.7%), in purebred than in crossbred (88.5% versus 81.8%), and in symptomatic than asymptomatic ones (95.7% versus 80.4%). T. verrucosum was as prevalent in semi-intensive as in intensive breeding system (88.2% versus 87.6%) but more prevalent in calves raised for meat rather than milk production (91.1% versus 84.9%), and reared under conventional than organic production management system (89.3% versus 82.6%). Prevalence rates were also higher when the cattle present in the farm were of mixed origin, rather than when the whole stock was purchased or was born in the farm (92% versus 88.2% and 85.7%), when other cattle in the farm were showing skin signs (90% versus 84.2%), and at least one case of human ringworm was recorded in the farm (90.9% versus 86.1%). No statistically significant association was found. Therefore, T. verrucosum infection may be more widespread in calves from Central Italy than it was previously thought to be. Calves of any sex, breed, age, and of any of the farm condition considered, are highly exposed to the risk of infection. As calves may play a considerable role as reservoirs of the infection, our results highlight the need to determine the incidence and the importance of T. verrucosum ringworm in personnel involved with cattle care in Italy and elsewhere.

Abstract
According to the American Society of Anesthe-siologists (ASA), a monitored anesthesia care (MAC) is a planned procedure during which the patient undergoes local anesthesia together with sedation and analgesia. Actually MAC is the first choice in 10-30% of all the surgical procedures. The 3 fundamental elements and purposes of a conscious sedation during a MAC are: a safe sedation, the control of the patient anxiety and the pain control. The patients undergoing conscious sedation are able to answer to orders appropriately and to protect airways. Last but not least, another purpose of any MAC is to get the patient appropriately satisfied, allowing him to get his discharge as faster as possible. There are many surgical procedures which can be performed using a MAC. The patient consciousness evaluation is of extreme importance during the surgical procedure performed with MAC: to this purpose the clinical and electroencephalographic evaluations such as Bispectral Index are very useful. MAC can be obtained with the association of fast half-life drugs or drugs getting a clinical effect which can vary according to the surgical requirements, using an infusion regiment. Apart from the pharmacological choice, this procedure can be performed with patient controlled sedation techniques or with continued intravenous infusion or with target controlled infusion.

Abstract
BACKGROUND Although imatinib is the standard treatment for chronic myeloid leukaemia, not all patients reach complete cytogenetic remission (CCR) and most maintain detectable disease at the molecular level. We investigated whether a vaccine targeting the BCR-ABL-derived p210 fusion protein was an active and specific immunotherapy. METHODS We recruited 16 patients who had chronic myeloid leukaemia (with the b3a2 fusion point of p210), stable residual disease, a minimum treatment of 12 months of imatinib or 24 months of interferon alfa, and no further reduction of residual disease for at least 6 months preceding enrollment. They were given six vaccinations with a peptide vaccine derived from the sequence p210-b3a2 plus molgramostim and QS-21 as adjuvants (CMLVAX100) before assessment of immunological and disease response, which included detecting amounts of b3a2 transcripts by standardised quantitative real-time reverse-transcriptase PCR. RESULTS Of ten patients on imatinib, nine started CMLVAX100 having had a median of 10 months' stable cytogenetic disease (median 10% Philadelphia-chromosome-positive metaphases), whereas one started in stable CCR. All patients' cytogenetic responses improved after six vaccinations, with five reaching CCR. Notably, three of these five patients also had undetectable amounts of b3a2 transcript (BCR-ABL:beta2 microglobulin ratio <0.00001). Six patients on interferon alfa treatment with a median of 17 months' stable residual disease (median 13% Philadelphia-chromosome-positive cells) were also vaccinated. All but one had improved cytogenetic responses, and two reached CCR. Overall, we recorded peptide-specific delayed-type hypersensitivity (in 11 of 16 patients), CD4 cell proliferation (13 of 14 assessed), and interferon gamma production (five of five assessed). INTERPRETATION Addition of CMLVAX100 to conventional treatment in patients with chronic myeloid leukaemia might favour further reduction of residual disease and increase the number of patients reaching a molecular response.

Abstract
Polymorphisms of the -106 mutation and z - 2 or z + 2 microsatellites (-2.1 kb) of the Aldose Reductase (AR) gene have been associated to microangiopathic complications of the diabetes mellitus. The study aimed to establish a relation between the occurrence and progression of the renal and retinal complications and these polymorphisms. The genotypes were realised in 3 populations: DESIR (n = 369), non-diabetic control subjects from the general French population: GENEDIAB (n = 494), type 1 diabetic patients who are suffering from proliferative retinopathy associated with a variable seriousness nephropathy (absent: n = 157; incipient: n = 104; established: n = 126; advanced: n = 107); SURGENE (n = 310), type 1 diabetic patients whom the renal status is prospectively assessed since 1989 in one single center Angers University Hospital. The genotype of the -106 polymorphism was determined using the Molecular Beacons. For the microsatellites analysis, we used an automatized method (GeneScan Abi Prism 3100). There was a strong linkage disequilibrium between the z - 2 allele and the T allele (chi 2 = 120; p = 0.001). The frequency of the C-106T is similar for the DESIR and GENEDIAB cohorts (chi 2 = 3.32; p = 0.19); the Hardy Weinberg law was verified in this group (chi 2 = 0.001, 0.9; p = 1.5 and 0.5 respectively). The law was not verified for the SURGENE cohort (chi 2 = 4.7; p = 0.03) where the frequency of the TT genotype was significantly more important compared to the DESIR population (chi 2 = 6.4; p = 0.01). The z, z - 2 and z + 2 alleles was more frequent compared with other alleles (n = 909, 830 and 349; 39, 38 and 15%). The frequency of the C-106T and microsatellites genotypes did not parallel the nephropathy staging in the GENEDIAB population (chi 2 = 10.9, 2.7, 2.4; p = NS respectively). In the SURGENE population, the survival without renal events did not differ according C-106T and z - 2 or z + 2 microsatellites genotypes (log-rank: 0.6, 3.9, 0.1; p = NS respectively). At the end of the follow-up, we found an effect of the -106 mutation and of the z - 2 microsatellite on the staging of the retinopathy (chi 2 tendency test = 4.61, 0.12; p = 0.031, 0.02; 6 d.f., respectively). The logistic regression multivariable analysis shows that the retinopathy during the final evaluation is independently explained by several factors: diabetes duration (p < 0.0001; OR 21.756; 95% CI: 7.024-67.389), presence of nephropathy (p < 0.0001; OR: 4.086; 95% CI: 2.094-7.973), and genotype TT (p = 0.011; OR: 0.38; 95% CI: 0.18-0.803). In contrast, age of diabetes onset (p = 0.112; OR: 1.556; 95% CI: 0.9-2.692), median HbA1c (p = 0.164; OR: 1.479; 95% CI: 0.85-2.576) and sex (p = 0.156; OR: 1.495; 95% CI: 0.856-2.612) have no independent effect. In conclusion, the association of these AR genetic variants seems absent about the renal risk and slight about the retinal risk associated to the type 1 diabetes mellitus.

Abstract
Type 2 diabetes mellitus is the main cause of increase in patients suffering from end-stage renal failure in France. We performed an observational study of the change in renal function of type 2 diabetic patients, attending our diabetology clinic. Clinical and biological data were regularly entered in an informatic database (Pénélope, Poitiers University Hospital). We prospectively followed 351 type 2 diabetic patients (age at diagnosis: 40 to 75 years), for 32 months (extremes: 1-120). Renal function was graded in 4 stages according to plasma creatinine and urinary albumin excretion (UAE) determined by nephelometry on random urinary sample: absent (UAE < 20 mg/L et creatinine < 150 mumol/L), incipiens (UAE 20 to 200 mg/L and creatinine < 150 mumol/L), established (UAE = 200 mg/L et creatinine < 150 mumol/L) advanced (creatinine = 150 mumol/L). Glycated haemoglobin (HbA1c) was determined by HPLC. Systolic/Diastolic Blood Pressure (SBP/DBP) was measured with a mercury sphygmomanometer. We defined renal events as the change from one stage of nephropathy to a higher one. A total of 351 type 2 diabetic subjects were studied: 194 men/157 women mean age 63 +/- 11 years, mean diabetes duration 10 +/- 9 yr. At baseline, 206 patients had no nephropathy, 98 incipient nephropathy, 28 established nephropathy and 19-advanced nephropathy. Baseline stage of nephropathy was related to SBP (p < 0.0001), DBP (p = 0.0002), diabetes duration (p = 0.0064) but not HbA1c (p = 0.2182) or sex (p = 0.4794). Among those 332 subjects without baseline advanced nephropathy, 134 progressed in nephropathy. Progression of nephropathy was not related to the presence of hypertension (SBP/DBP > or = 160/95 mmHg) (log-rank = 0.22; p = 0.6377). Conversely, patients with a poor glycaemic control (HbA1c > or = 10%) had a worse renal-event free survival (log-rank = 4.89; p = 0.0269). Glycaemic control is a risk factor for the progression in nephropathy of type 2 diabetic patients.

Abstract
We report the case of a 52-year-old woman with long-term type 1 diabetes mellitus, complicated with proliferative retinopathy, autonomic neuropathy and microalbuminuria and moderate renal failure. A normochromic, normocytic are generative anaemia had been diagnosed for three years. Clinical and biological investigations for the aetiology of anaemia remained normal or negative. Anaemia was associated with a concentration of erythropoietin (EPO) in the normal range, but inappropriately low regarding anaemia. Treatment with recombinant EPO induced a rapid increase in haemoglobin level and improved the patient's quality of life. The role of diabetic neuropathy in the genesis of anaemia, in conjunction with a modest renal impairment is discussed.

Abstract
AIMS To assess differences in circulating leptin and glucagon-like peptide (GLP)-1 concentrations before and after an oral glucose load, in euglycaemic and isoinsulinaemic conditions, between obese patients with and without Type 2 diabetes mellitus. METHODS Ten male obese (body mass index (BMI) > 30 kg/m2) patients with Type 2 diabetes and 20 matched non-diabetic subjects were studied. Leptin, GLP-1(7-36)amide and GLP-1(7-37) concentrations were measured 0, 30, 60, and 90 min after a 50-g oral glucose load administered 90 min after the beginning of a euglycaemic hyperinsulinaemic clamp. RESULTS GLP-1(7-36)amide concentrations before the glucose load were significantly lower in diabetic patients than in controls (median (quartiles): 50.5 (44.7-53.2) vs. 128.7(100-172.5) pg/ml; P < 0.01), while no difference was observed in baseline GLP-1(7-37). In non-diabetic subjects, GLP-1(7-36)amide and GLP-1(7-37) concentrations increased significantly after the oral glucose load, while no glucose-induced increase in GLP-1 concentration was observed in diabetic patients. GLP-1(7-36)amide at 30, 60, and 90 min, and GLP-1(7-37) at 30 min, of the glucose challenge, were significantly lower in diabetic patients. Leptin concentrations were not significantly different in diabetic patients when compared to non-diabetic subjects, and they did not change after the oral glucose load. DISCUSSION Leptin concentrations are not significantly modified in obese Type 2 diabetic patients. GLP-1(7-36)amide baseline concentrations are reduced in Type 2 diabetes; moreover, diabetic subjects show an impaired response of GLP-1 to oral glucose in euglycaemic, isoinsulinaemic conditions. This impairment, which is not the result of differences in glycaemia or insulinaemia during assessment, could contribute to the pathogenesis of hyperglycaemia in Type 2 diabetes mellitus.

Abstract
Objective information was obtained from 89 textbooks in the psychology of learning published from 1952 through 1995 to answer questions about their coverage of classical conditioning. We found (a) that classical conditioning consistently received less coverage than instrumental and operant conditioning, (b) that the distinction of classical and instrumental conditioning has become established as a textbook-construction device, (c) that use of the classical-instrumental distinction by textbook authors has "hardened" after a period of "fluidity" in the 1970s, (d) that the currency of references in the basic classical (as well as instrumental) conditioning chapters diminished from 1952 to 1995. Findings are discussed in regard to the possibility that, as a class, and in comparison to other textbooks, the textbooks of the psychology of learning fall short of fulfilling some of their recognized roles.

Abstract
The amplification of c-erbB-2 oncogene has been reported to have clinical relevance as a prognostic index in breast cancer. However, controversies still remain about its interpretation, mainly due to the inaccuracy of methods used for this purpose and to the unpredictable variability of the ratio between cancer and normal cells. Accurate quantitative assay, combined with strategies for selection or enrichment of tumor cell populations, could shed a new light on the relationships between molecular alterations and their clinical relevance. In this study, amplification of c-erbB-2 was measured by competitive PCR in 21 aneuploid breast cancers using a multiple DNA competitor both in whole homogenized cancer cells and in aneuploid enriched clones obtained after flow cytometry cell sorting. Most breast cancers (10/12) carrying c-erbB-2 oncogene amplification showed a significant increase in copy number in sorted aneuploid clones, and 2/9 apparently not amplified in basal samples were found to be amplified after being sorted for the aneuploid population. A general concordance between amplification and c-erbB-2 overexpression was found. The mean degree of amplification in sorted aneuploid clones is increased in breast cancers with the highest levels of c-erbB-2 protein overexpression. These data indicate that in breast cancers the amplification of c-erbB-2 oncogene is mainly associated with aneuploid cells.

Abstract
Nuclear hormone receptors comprise a large family of zinc finger transcription factors, some with hydrophobic ligands, such as thyroid hormone, vitamin D, steroids, etc., and others for which no ligand has been found. Thyroid hormone receptors (TRs) generally are considered to be confined to the vertebrata that possess a thyroid gland. Tunicates represent the most primitive of the chordates, and there are data supporting a role for thyroid hormone in their metamorphosis, but no data are available on TRs in this genus; hence, we have studied Ciona intestinalis. Screening of a Ciona library with the DNA binding domain of Xenopus laevis TR (xTR) resulted in the isolation of a nuclear hormone receptor, C. intestinalis nuclear receptor 1 (CiNR1). CiNR1 is similar to TRs of more evolved species with a conserved DNA binding domain whereas the ligand binding domain shows poor homology to vertebrate sequences. The C-terminal part of CiNR1 spans approximately 200 amino acids more than other TRs, lacks the AF2 transactivation domain, and is not able to bind triiodothyronine. Phylogenetically, CiNR1 appears to be close to the common ancestral gene of TRs. Expression of CiNR1 was limited to the developing embryo and the larval stage, which suggests a role during development and metamorphosis. In transfection experiments, CiNR1 down-regulated basal transcription of a reporter gene driven by the TR palindrome responsive element. When CiNR1 was cotransfected with chicken TRalpha, it attenuated the normal thyroid hormone response in a dominant negative fashion. This attenuation required the C-terminal portion of the molecule.
