Abstract
OBJECTIVES The aim of this study was to assess the prevalence of malnutrition, the clinical characteristics associated with malnutrition and the impact of nutritional status on mortality, quality of life, self-care abilities, and activities of daily living in the older patients with advanced heart failure. METHODS A prospective multicentre cohort study including 260 community-dwelling elderly patients with advanced HF was conducted between June 2017 and December 2019. The study was carried out in 22 primary healthcare centres, three university hospitals, one acute-care hospital, and one geriatric rehabilitation unit in the city of Barcelona (Spain). Nutritional status was assessed at baseline using the Mini Nutritional Assessment questionnaire. Patient-reported outcome measures included quality of life (EQ-5D-3L), self-care behaviour (European Heart Failure Self-care Behaviour Scale) and impact on activities of daily living (Barthel Index). RESULTS Using the MNA-SF, 126 (48.5%) patients were identified as being at risk of malnutrition and 33 (12.7%) patients as having confirmed malnutrition. Compared to HF patients with normal nutritional status, patients with confirmed malnutrition were significantly older, with a lower BMI, and with reduced haemoglobin levels. During follow-up (median 14.9 months, Interquartile Range; 4.9-26.9), 133 (51.2%) of the included participants died, and mortality was significantly higher among patients identified as having malnutrition (p < 0.001). Better Barthel index and quality of life scores were inversely related to the risk of malnutrition, [Odds Ratio (OR) 0.97 (95% Confidence interval 0.96; 0.98) and OR 0.98 (95% Confidence interval, 0.96; 0.99)], respectively. Higher scores in the European Heart Failure Self-care Behaviour Scale, which implies worse self care, were related to higher malnutrition risk, OR 1.05 (95% Confidence interval, 1.02; 1.09. Adjusted multivariate logistic model found that malnutrition was significantly associated with poor quality of life, and adverse impacts on daily activities and self-care. CONCLUSIONS In community-dwelling older patients with advanced HF, malnutrition was associated with worse patient reported outcome measures related to poor quality of life, and adverse impacts on self-care and daily activities. Nutritional status must be systematically addressed by primary care nurses and family doctors to improve survival rates in these patients. It would be helpful the incorporation of expert professionals in nutrition in the primary health care centres.

Abstract
A progressively increasing percentage of the elderly live during the last years of their lives in nursing homes. Although these institutions are intended to mimic life at home as much as possible, they have characteristics that make them quite similar to a “nosocomiun”, i.e. an establishment for the treatment of the sick. The very coexistence among the elderly, the fact of sharing caregivers and the very significant exposure to third parties, together with the frequent predisposing diseases to infection in this population, make infection frequent among residents and also easily transmissible. This leads us to ask what can be done to prevent infection in this environment and more specifically what is the state of the art of the matter in a Western European nation such as ours. The Board of Trustees of the Health Sciences Foundation has asked itself a series of questions on the subject of infection prevention in Nursing Homes, the structure of procedures, the legislation available, compliance with the measures indicated, the best indicators of the processes and therefore, the need to promote in Spain a document of recommendations to avoid infections in this poplation whose morbidity and mortality need not be highlighted. To this end, a multidisciplinary group of experts in different aspects of this problem has been convened and asked the proposed questions. The questions were discussed by the group as a whole and led to a series of conclusions agreed upon by the participants. The results of the meeting are reported below.

Abstract
Abstract
Study question
Can we accurately assess sex-chromosomes number in testicular cells (germ and somatic) of Klinefelter Syndrome (KS) prepuberal patients by DNA-FISH in paraffin embedded sections?
Summary answer
We have evaluated the sex-chromosomes content of testicular cells in KS prepuberal patients and the presence of XY lines evidenced a gonadal mosaicism status.
What is known already
Prepuberal boys with Klinefelter Syndrome usually have fertility problems in adulthood, mainly azoospermia. Due to the symptoms cause by the disease, Spermatogonial Stem Cells (SSCs) are less abundant and spermatogenesis does not occur. These patients do not have any alternative to restore the fertility in the future. When a boy has both XY and XXY cell lines, this patient is mosaic (46,XY/47,XXY). Meaning some cells could undergo spermatogenesis and generate gametes with normal sex-chromosomes number. The aim of this work is to test if KS patients diagnosed as pure can have testicular cell lines with XY chromosome number (mosaic).
Study design, size, duration
We obtained samples from human prepuberal patients diagnosed with pure Klinefelter Syndrome (47,XXY) for the last 5 years. Testicular biopsy fragments are fixed for histological studies and other fragments are cryopreserved. Some fragments are used for immunofluorescence and subsequently processed by DNA-FISH to determine the sex-chromosomes content of testicular cells.
Participants/materials, setting, methods
In this study, we used 10 prepuberal patients with KS and 5 prepuberal patients with other fertility problems with normal chromosome set as controls. We performed immunofluorescence to determine expression of germ cells (VASA) and SSCs (MAGEA4) markers and somatic cells markers such as Leydig cells (StAR) and Sertoli cells (SOX9). Afterwards, we perform DNA-FISH, with probes specific for chromosomes X and Y and chromosome 18 as a control.
Main results and the role of chance
The methodology used allows cytogenetic characterization of testicular tissue in paraffin embedded sections. Testicular mosaicism has been observed in all patients diagnosed as pure KS. We have observed a degree of mosaicism of 66-80% in SSCs, of 20-50% in Sertoli cells and of 30-50% in Leydig cells.
We pursued a protocol with a good FISH efficiency that allows colocalization of previous immunocharacterized testicular cells.
Limitations, reasons for caution
The DNA-FISH technique is made just in a single paraffin section of each KS patient testicular sample. Due to the limited and difficulty to obtain KS testicular tissue, we use a limited number of samples.
Wider implications of the findings
We succeed to demonstrate the mosaicism of testicular cells in prepuberal patients that are diagnosed with KS. Thus, the better understanding of the SSCs with normal chromosome set (XY) could be useful for future in vitro expansion and stem cell therapies.

Abstract
Abstract
Background/Introduction
Pulmonary artery aneurysm (PAA), defined as a pulmonary artery (PA) diameter >40 mm, is a common finding among pulmonary arterial hypertension (PAH) patients. Although often asymptomatic, PAA may lead to life-threatening complications such as left main coronary artery compression or PA dissection. Transthoracic echocardiography (TTE) is regularly employed for risk assessment in PAH patients. However, TTE accuracy for PA measurement has not been evaluated, and current practice guidelines lack formal recommendations for PAA screening and follow-up. We aim to determine whether TTE is an appropriate tool for PA diameter measurement and determine an optimal cut-off point to diagnose a PAA through TTE.
Methods
We retrospectively analyzed a cohort of 657 PAH patients followed up at a national referral centre. For this analysis, we selected those patients who had undergone at least one TTE and one computed tomography (CT) or magnetic resonance (MR) within six months before or after the TTE. We performed an agreement analysis between CT/MR-based and TTE-based PA diameter using the Passing–Bablok method. Furthermore, we calculated the area under the curve for the identification of a PAA with a TTE (compared to CT/MR).
Results
We analyzed 281 simultaneous CT/MR and TTE of a total of 178 PAH patients (71% women). Median age at diagnosis was 42.1 (32.2–58.0) years. PAH etiology was idiopathic or familial in 67 (38%), associated with congenital heart disease in 28 (16%) and associated with connective tissue disease in 36 (20%) patients. In 46 (26%) patients PAH was associated with other entities, such as human immunodeficiency virus, pulmonary veno-occlusive disease, drugs or portal hypertension. We found a significant correlation between PA diameter measured in TTE and CT/CMR (Lin's concordance correlation coefficient = 0.851) (Figure 1). The area under the curve for the detection of PAA was 0.91 (95% CI 0.88–0.95, p=0.018) (Figure 2). We selected a TTE-based PA diameter 37 mm as the optimal cut-off point for PAA identification. This diameter correctly classified 85.4% of measurements with a sensitivity and a specificity of 83.2% and 87.2%, respectively.
Conclusion
Our study demonstrates that TTE is an adequate tool for PA diameter quantification with a strong correlation with CT/MR. This good correlation makes TTE an excellent tool for PAA screening among PAH patients, avoiding unnecessary CT or MR scan and helping to identify those patients in whom close follow-up is advisable. Based on these results, we recommend the inclusion of PA diameter measurement in TTE acquisition protocols for PAH patients.

Abstract
BACKGROUND Quantitative, reverse transcription PCR (qRT-PCR) is currently the gold-standard for SARS-CoV-2 detection and it is also used for detection of other virus. Manual data analysis of a small number of qRT-PCR plates per day is a relatively simple task, but automated, integrative strategies are needed if a laboratory is dealing with hundreds of plates per day, as is being the case in the COVID-19 pandemic. RESULTS Here we present shinyCurves, an online shiny-based, free software to analyze qRT-PCR amplification data from multi-plate and multi-platform formats. Our shiny application does not require any programming experience and is able to call samples Positive, Negative or Undetermined for viral infection according to a number of user-defined settings, apart from providing a complete set of melting and amplification curve plots for the visual inspection of results. CONCLUSIONS shinyCurves is a flexible, integrative and user-friendly software that speeds-up the analysis of massive qRT-PCR data from different sources, with the possibility of automatically producing and evaluating melting and amplification curve plots.

Abstract
PURPOSE The outcomes of five fraction stereotactic radiotherapy (hfSRT) following brain metastasectomy were evaluated and compared with published series. METHODS 30 Gy in 5 fractions HfSRT prescribed to the surgical cavity was reduced to 25 Gy if the volume of 'brain-GTV' receiving 20 Gy exceeded 20 cm3. Endpoints were local recurrence, nodular leptomeningeal recurrence, new brain metastases and radionecrosis. The literature was searched for reports of clinical and dosimetric outcomes following postoperative hfSRT in 3-5 fractions. RESULTS 39 patients with 40 surgical cavities were analyzed. Cavity local control rate at 1 year was 33/40 (82.5%). 3 local failures followed 30 Gy/5 fractions and 4 with 25 Gy/5 fractions. The incidence of leptomeningeal disease (LMD) was 7/40 (17.5%). No grade 3-4 toxicities, particularly no radionecrosis, were reported. The incidence of distant brain metastases was 15/40 (37.5%). The median overall survival was 15 months. Across 13 published series, the weighted mean local control was 83.1% (adjusted for sample size), the mean incidence of LMD was 14.9% (7-34%) and the mean rate of radionecrosis was 10.3% (0-20.6%). CONCLUSION Postoperative hfSRT can be delivered with 25-30 Gy in 5 fractions with efficacy in excess of 82% and no significant toxicity when the dose to 'brain-GTV' does not exceed 20 cm3.

Abstract
BACKGROUND In patients with active Crohn's disease (CD), treatment of intra-abdominal abscess usually comprises antibiotics and radiologically guided percutaneous drainage (PD) preceding surgery. The aim of this study was to investigate the risk of postoperative complications and identify the optimal time interval for surgical intervention after PD. METHODS A multicentre, international, retrospective cohort study was carried out. Details of patients with diagnosis of CD who underwent ultrasonography- or CT-guided PD were retrieved from hospital records using international classification of disease (ICD-10) diagnosis code for CD combined with procedure code for PD. Clinical variables were retrieved and the following outcomes were measured: 30-day postoperative overall complications, intra-abdominal septic complications, unplanned intraoperative adverse events, surgical-site infections, sepsis and pathological postoperative ileus, in addition to abscess recurrence. Patients were categorized into three groups according to the length of the interval from PD to surgery (1-14 days, 15-30 days and more than 30 days) for comparison of outcomes. RESULTS The cohort comprised 335 CD patients with PD followed by surgery. Median age was 33 (i.q.r. 24-44) years, 152 (45.4 per cent) were females, and median disease duration was 9 (i.q.r. 3.6-15) years. Overall, the 30-day postoperative complications rate was 32.2 per cent and the mortality rate was 1.5 per cent. After adjustment for co-variables, older age (odds ratio 1.03 (95 per cent c.i. 1.01 to 1.06), P < 0.012), residual abscess after PD (odds ratio 0.374 (95 per cent c.i. 0.19 to 0.74), P < 0.014), smoking (odds ratio 1.89 (95 per cent c.i. 1.01 to 3.53), P = 0.049) and low serum albumin concentration (odds ratio 0.921 (95 per cent c.i. 0.89 to 0.96), P < 0.001) were associated with higher rates of postoperative complications. A short waiting interval, less than 2 weeks after PD, was associated with a high incidence of abscess recurrence (odds ratio 0.59 (95 per cent c.i. 0.36 to 0.96), P = 0.042). CONCLUSION Smoking, low serum albumin concentration and older age were significantly associated with postoperative complications. An interval of at least 2 weeks after successful PD correlated with reduced risk of abscess recurrence.

Abstract
AIMS OF THE STUDY The presence of colostomy has a major impact on quality of life that could potentially be improved by performing colonic irrigation (CI), yet few studies have assessed the impact of this technique on quality of life. The aim of this study was to assess the quality of life between two groups of patients having a colostomy; those practicing CI vs those not practicing CI. PATIENTS AND METHODS The French Federation of Ostomy (FFO) members were evaluated by a self-questionnaire assessing their experience of CI. Quality of life as assessed by the Stoma-QOL questionnaire was compared between patients practicing CI or not. RESULTS In total 752 patients were eligible for the study. The median age was 75 years, and 47.26% were men. The median duration between stoma surgery and questionnaire completion was 12.3 years. Forty-one percent of the patients practiced CI. The median quality of life score was significantly higher for the patients practicing the CI: (69.26 vs 58.33, P<0.001). In multivariable analysis, the risk factors for not performing CI were age, obesity, the presence of colostomy for less than six years, and a non-oncologic indication for operation. CONCLUSIONS CI appeared to improve the quality of life of patients with colostomy. This care is a therapeutic education issue and should be proposed to all patients. Supervision by the enterostomal therapy nurse is recommended especially for patients with a high risk of failure.

Abstract
Being at the western fringe of Europe, Iberia had a peculiar prehistory and a complex pattern of Neolithization. A few studies, all based on modern populations, reported the presence of DNA of likely African origin in this region, generally concluding it was the result of recent gene flow, probably during the Islamic period. Here, we provide evidence of much older gene flow from Africa to Iberia by sequencing whole genomes from four human remains from northern Portugal and southern Spain dated around 4000 years BP (from the Middle Neolithic to the Bronze Age). We found one of them to carry an unequivocal sub-Saharan mitogenome of most probably West or West-Central African origin, to our knowledge never reported before in prehistoric remains outside Africa. Our analyses of ancient nuclear genomes show small but significant levels of sub-Saharan African affinity in several ancient Iberian samples, which indicates that what we detected was not an occasional individual phenomenon, but an admixture event recognizable at the population level. We interpret this result as evidence of an early migration process from Africa into the Iberian Peninsula through a western route, possibly across the Strait of Gibraltar.

Abstract
Abstract
An interlaboratory study was performed on behalf of the UK Food Standards Agency to evaluate the effectiveness of an affinity column cleanup liquid chromatography (LC) method for the determination of zearalenone (ZON) in a variety of cereals and cereal products at proposed European regulatory limits. The test portion is extracted with acetonitrile:water. The sample extract is filtered, diluted, and applied to an affinity column. The column is washed, and ZON is eluted with acetonitrile. ZON is quantified by reversed-phase LC with fluorescence detection. Barley, wheat and maize flours, polenta, and a maize-based baby food naturally contaminated, spiked, and blank (very low level) were sent to 28 collaborators in 9 European countries and 1 collaborator in New Zealand. Participants were asked to spike test portions of all samples at a ZON concentration equivalent to 100 μg/kg. Average recoveries ranged from 91–111%. Based on results for 4 artificially contaminated samples (blind duplicates) and 1 naturally contaminated sample (blind duplicate), the relative standard deviation for repeatability (RSDr) ranged from 6.9–35.8%, and the relative standard deviation for reproducibility (RSDR) ranged from 16.4–38.2%. The method showed acceptable within- and between-laboratory precision for all 5 matrixes, as evidenced by HorRat values <1.7.

Abstract
Abstract
Interlaboratory validation studies have been performed on 2 methods for the determination of chlormequat (CLQ) and mepiquat (MPQ). Both methods used identical extraction procedures and stable isotope internal standardization but differed in the use of liquid chromatography/mass spectrometry (LC/MS) or LC/tandem mass spectrometry (LC/MS/MS) for the determination, the amount of internal standard used, and the expected limit of detection. After addition of deuterated internal standards, CLQ and MPQ were extracted with methanol–water and determined by LC/MS or LC/MS/MS with positive electrospray ionization. Eight European laboratories participated in the LC/MS method study, analyzing mushroom, pear, wheat flour, and fruit puree with residues of CLQ in the range 0.040–1.19 mg/kg and of MPQ in the range 0.041–0.39 mg/kg. For CLQ, the Horwitz ratio (HoRat) values for individual test materials/levels were in the range 0.85–1.13 with amean of 1.00, showing good method performance. For MPQ, the Ho values for mushroom, pear (both levels), and wheat flour were in the range 0.83–0.94, again indicating good method performance. For the determination of MPQ in infant food (fruit puree) at 0.041 mg/kg, the Ho was 1.7 when a value of 0 reported by one participant was excluded. In the LC/MS/MS study, in which 11 laboratories participated, a separate sample set was analyzed with residues of CLQ in the range 0.007–1.03 mg/kg and of MPQ in the range 0.008–0.72 mg/kg. Ho values for CLQ were in the range 0.27–1.36 and for MPQ in the range 0.51–2.10, all corresponding to acceptable method performance.

Abstract
OECI TuBaFrost harbors a complete infrastructure for the exchange of frozen tumor samples between European countries. OECI TuBaFrost consists of: • A code of conduct on how to exchange human residual samples in Europe • A central database application accessible over the Internet ( www.tubafrost.org ) where data can be uploaded and searched from samples that can be selected and ordered • Access rules with incentives for collectors • Standardization needed to enable the analysis of high quality samples derived from different centers • Virtual Microscopy to support sample selection with difficult pathology The entire infrastructure was, after completion, which was entirely financed by the European Commission, implemented in the OECI. But so far it has not been used to its capacity. A recent survey held amongst the OECI members shed light on the causes. The main conclusion is that all responders see OECI TuBaFrost as a good platform for exchange of samples, however, the biggest bottleneck found was that potential users are too unfamiliar with the communication between their own biobank tracking system and the TuBaFrost central database application. Therefore, new future plans are drawn. In addition, new infrastructure plans have been developed and the first preparatory steps have been set. For biobanks the BBMRI project has started aiming for Pan-European Biobanking and Biomolecular Resources Research Infrastructure.

Abstract
AIM Anastomotic leak is associated with higher rates of recurrence after surgery for colorectal cancer. However, the mechanisms responsible are unknown. We hypothesized that the infection-induced inflammatory response may induce overexpression of tumour progression-related genes in immune cells. The aim was to investigate the effect of postoperative intra-abdominal infection on the gene expression patterns of peripheral blood leucocytes (PBL) after surgery for colorectal cancer. METHOD Prospective matched cohort study. Patients undergoing surgery for colorectal cancer were included. Patients who had anastomotic leak or intra-abdominal abscess were included in the infection group (n = 23) and matched with patients without complications for the control group (n = 23). PBL were isolated from postoperative blood samples. Total RNA was extracted and hybridized to the Affymetrix Human Gene 1.0 ST microarray. RESULTS Patients in the infection group displayed 162 upregulated genes and 146 downregulated genes with respect to the control group. Upregulated genes included examples coding for secreted cytokines involved in tumour growth and invasion (S100P, HGF, MMP8, MMP9, PDGFC, IL1R2). Infection also upregulated some proangiogenic genes (CEP55, TRPS1) and downregulated some inhibitors of angiogenesis (MME, ALOX15, CXCL10). Finally, some inhibitors (HP, ORM1, OLFM4, IRAK3) and activators (GNLY, PRF1, FGFBP2) of antitumour immunity were upregulated and downregulated, respectively, suggesting that the inflammatory environment caused by a postoperative infection favours immune evasion mechanisms of the tumour. CONCLUSION Analysis of PBL shows differential expression of certain tumour progression-related genes in colorectal cancer patients who have a postoperative intra-abdominal infection, which in turn may promote the growth of residual cancer cells to become recurrent tumours.

Abstract
Patients with HCV genotype 3 (GT3) infection and cirrhosis are currently the most difficult to cure. We report our experience with sofosbuvir+daclatasvir (SOF+DCV) or sofosbuvir/ledipasvir (SOF/LDV), with or without ribavirin (RBV) in clinical practice in this population. This was a multicenter observational study including cirrhotic patients infected by HCV GT3, treated with sofosbuvir plus an NS5A inhibitor (May 2014-October 2015). In total, 208 patients were included: 98 (47%) treatment-experienced, 42 (20%) decompensated and 55 (27%) MELD score >10. In 131 (63%), treatment was SOF+DCV and in 77 (37%), SOF/LDV. Overall, 86% received RBV. RBV addition and extension to 24 weeks was higher in the SOF/LDV group (95% vs 80%, P=.002 and 83% vs 72%, P=.044, respectively). A higher percentage of decompensated patients were treated with DCV than LDV (25% vs 12%, P=.013). Overall, SVR12 was 93.8% (195/208): 94% with SOF+DCV and 93.5% with SOF/LDV. SVR12 was achieved in 90.5% of decompensated patients. Eleven treatment failures: 10 relapses and one breakthrough. RBV addition did not improve SVR (RR: 1.08; P=.919). The single factor associated with failure to achieve SVR was platelet count <75×10E9/mL (RR: 3.50, P=.019). In patients with MELD <10, type of NS5A inhibitor did not impact on SVR12 (94% vs 97%; adjusted RR: 0.49). Thirteen patients (6.3%) had serious adverse events, including three deaths (1.4%) and one therapy discontinuation (0.5%), higher in decompensated patients (16.7% vs 3.6%, P<.006). In patients with GT3 infection and cirrhosis, SVR12 rates were high with both SOF+DCV and SOF/LDV, with few serious adverse events.

Abstract
BACKGROUND The aim of this study was to identify predictors of overall survival (OS), disease-free survival (DFS), and recurrence in a cohort of 151 patients with hepatocellular carcinoma (HCC) and cirrhosis who were treated by liver transplantation (LT). PATIENTS AND METHODS A retrospective database of patients undergoing LT for radiologically diagnosed HCC at "12 de Octubre" Hospital, Madrid during 1986-2006 was analyzed. RESULTS The median follow-up was 67.44 months (SD = 55.7 months). Overall 1-, 3-, 5-, and 10-year survival was 87.5%, 73.7%, 64.1% and 43.4%, respectively. The 5-year OS of patients beyond the Milan criteria was 47.14%, whereas that of patients within the Milan criteria was 70.13% (P = .011). The 5-year OS of patients beyond the Milan criteria and with microvascular invasion (MVI) was 27.27%, whereas that of patients beyond the Milan criteria and without MVI criteria was 57.89% (P = .003). Multivariate analysis of prognostic factors revealed MVI and G3 to be independent and statistically significant factors affecting OS (P < .0001 and P = .045, respectively), DFS (P < .0001 and P = .004, respectively), and recurrence (P = .0002 and P = .028, respectively). Multivariate analysis of prognostic factors also revealed preoperative fine-needle aspiration (FNA) to be an independent negative statistically significant factor affecting recurrence (P = .0022). Multivariate analysis of predictive MVI factors revealed preoperative α-fetoprotein (AFP) levels >200 ng/mL to be an independent positive and statistically significant predictor of MVI (P = .0004). CONCLUSION MVI and G3 are independent negative factors affecting OS, DFS, and recurrence. The presence of MVI or AFP levels >200 ng/mL represent a contraindication for LT, as long as the patient is beyond the Milan criteria.

Abstract
OBJECTIVE To evaluate whether cranberries are able to prevent postoperative urinary bacteriuria in patients undergoing pelvic surgery and receiving transurethral catheterisation. DESIGN Randomised, double-blind, placebo-controlled trial. SETTINGS French tertiary Care centre, University Hospital. POPULATION A total of 272 women undergoing pelvic surgery aged 18 or older. METHODS Participants undergoing pelvic surgery were randomised to 36 mg cranberry (proanthocyanidins, PAC) or placebo once daily for 10 days. Statistical analysis was performed by a chi-square test. MAIN OUTCOME MEASURES The primary and secondary outcomes were postoperative bacteriuria, defined by a positive urine culture, within the first 15 and 40 days, respectively. RESULTS Two hundred and fifty-five participants received the intended treatment: 132 (51.8%) received PAC and 123 (48.2%) received placebo. There were no significant differences in baseline demographics, intra-operative characteristics or duration and type of catheterisation between the two groups. PAC prophylaxis did not reduce the risk of bacteriuria treatment within 15 days of surgery [27% bacteriuria with PAC compared with 25% bacteriuria with placebo: relative risk 1.05, 95% CI 0.78-1.4, P = 0.763). The same result was observed on day 40. Bacteriuria occurred more often in older women with increased length of catheterisation. CONCLUSION Immediate postoperative prophylaxis with PAC does not reduce the risk of postoperative bacteriuria in patients receiving short-term transurethral catheterisation after pelvic surgery. TWEETABLE ABSTRACT PAC prophylaxis does not reduce the risk of postoperative bacteriuria in patients undergoing pelvic surgery.

Abstract
AIMS Nasal carriage of Staphylococcus aureus in diabetic patients may be a risk factor for diabetic foot lesion infections. The aims of this study were to compare the genotypic profiles of S. aureus strains isolated from nares and diabetic foot ulcers (DFUs) using microarray technology. METHODS Patients were included if they were admitted for diabetic foot infection (DFI) at any of three diabetology departments of Montpellier and Nîmes University Hospitals between 1 September 2010 to 30 June 2012. All S. aureus isolates were analyzed using oligonucleotides arrays; S. aureus resistance and virulence genes were determined and each isolate was affiliated to a clonal complex. RESULTS The prevalence of S. aureus nasal carriage among the 276 included patients was 39.5% (n=109), while 36.6% (n=101) had S. aureus at both sites (nares and foot wounds) and, of these patients, 65.3% of patients harboured the same strain at both sites. In addition, the spread of the methicillin-resistant S. aureus (MRSA) ST398 clone in DFI and its tropism for bone were also further confirmed. CONCLUSION These findings appear to provide new arguments in favour of the systematic detection of nasal S. aureus carriage to anticipate the management of DFI.

Abstract
After the dispersal of modern humans (Homo sapiens) Out of Africa, hominins with a similar morphology to that of present-day humans initiated the gradual demographic expansion into Eurasia. The mitogenome (33-fold coverage) of the Peştera Muierii 1 individual (PM1) from Romania (35 ky cal BP) we present in this article corresponds fully to Homo sapiens, whilst exhibiting a mosaic of morphological features related to both modern humans and Neandertals. We have identified the PM1 mitogenome as a basal haplogroup U6*, not previously found in any ancient or present-day humans. The derived U6 haplotypes are predominantly found in present-day North-Western African populations. Concomitantly, those found in Europe have been attributed to recent gene-flow from North Africa. The presence of the basal haplogroup U6* in South East Europe (Romania) at 35 ky BP confirms a Eurasian origin of the U6 mitochondrial lineage. Consequently, we propose that the PM1 lineage is an offshoot to South East Europe that can be traced to the Early Upper Paleolithic back migration from Western Asia to North Africa, during which the U6 lineage diversified, until the emergence of the present-day U6 African lineages.

Abstract
The current European Union (EU) legislation decrees that pets entering the EU from a rabies-infected third country have to obtain a satisfactory virus-neutralizing antibody level, while those moving within the EU require only rabies vaccination as the risk of moving a rabid pet within the EU is considered negligible. A number of factors driving individual variations in dog vaccine response have been previously reported, including a high rate of vaccine failure in puppies, especially those subject to commercial transport. A total of 21 001 observations collected from dogs (2006-2012) vaccinated in compliance with the current EU regulations were statistically analysed to assess the effect of different risk factors related to rabies vaccine efficacy. Within this framework, we were able to compare the vaccination failure rate in a group of dogs entering the Italian border from EU and non-EU countries to those vaccinated in Italy prior to international travel. Our analysis identified that cross-breeds and two breed categories showed high vaccine success rates, while Beagles and Boxers were the least likely to show a successful response to vaccination (88.82% and 90.32%, respectively). Our analysis revealed diverse performances among the commercially available vaccines, in terms of serological peak windows, and marked differences according to geographical area. Of note, we found a higher vaccine failure rate in imported dogs (13.15%) than in those vaccinated in Italy (5.89%). Our findings suggest that the choice of vaccine may influence the likelihood of an animal achieving a protective serological level and that time from vaccination to sampling should be considered when interpreting serological results. A higher vaccine failure in imported compared to Italian dogs highlights the key role that border controls still have in assessing the full compliance of pet movements with EU legislation to minimize the risk of rabies being reintroduced into a disease-free area.

Abstract
Pattern formation often occurs in spatially extended physical, biological, and chemical systems due to an instability of the homogeneous steady state. The type of the instability usually prescribes the resulting spatio-temporal patterns and their characteristic length scales. However, patterns resulting from the simultaneous occurrence of instabilities cannot be expected to be simple superposition of the patterns associated with the considered instabilities. To address this issue, we design two simple models composed by two asymmetrically coupled equations of non-conserved (Swift-Hohenberg equations) or conserved (Cahn-Hilliard equations) order parameters with different characteristic wave lengths. The patterns arising in these systems range from coexisting static patterns of different wavelengths to traveling waves. A linear stability analysis allows to derive a two parameter phase diagram for the studied models, in particular, revealing for the Swift-Hohenberg equations, a co-dimension two bifurcation point of Turing and wave instability and a region of coexistence of stationary and traveling patterns. The nonlinear dynamics of the coupled evolution equations is investigated by performing accurate numerical simulations. These reveal more complex patterns, ranging from traveling waves with embedded Turing patterns domains to spatio-temporal chaos, and a wide hysteretic region, where waves or Turing patterns coexist. For the coupled Cahn-Hilliard equations the presence of a weak coupling is sufficient to arrest the coarsening process and to lead to the emergence of purely periodic patterns. The final states are characterized by domains with a characteristic length, which diverges logarithmically with the coupling amplitude.

Abstract
BACKGROUND Anastomotic leakage is associated with higher rates of recurrence after surgery for colorectal cancer. However, the mechanisms responsible are unknown. The aim was to investigate the inflammatory and angiogenic responses in patients undergoing surgery for colorectal cancer who had postoperative intra-abdominal infection, and to compare the results with patients without complications. METHODS Consecutive patients undergoing surgery for colorectal cancer with curative intent were included. Patients who had an anastomotic leak or intra-abdominal abscess were included in the infection group and matched with patients who had an uncomplicated postoperative course. IL-6 and VEGF were measured in serum and peritoneal fluid. RESULTS Serum concentration of IL-6 was higher in the infection group (n = 30) compared with the control group (n = 30) on day 4 (infection: 42.3 [27.6-1473.2] versus control: 0.6 [0.6-17.1] pg/ml; p = 0.008). IL-6 in peritoneal fluid was higher in the infection group at 48 h and day 4 (infection: 1000.2 [995.4-1574.0] versus control: 90.3 [35.2.6-106.1] pg/ml; p = 0.001). Serum VEGF was higher in the infection group on day 4 (infection: 1128.6 [427.3-10000.0] versus control: 438.3 [214.1-677.6] pg/ml; p = 0.001). Peritoneal VEGF concentration was higher in the infection group at 48 h and day 4 (infection: 10000.0 [2563.0-10000.0] versus control: 477.8 [313.5-814.4] pg/ml; p = 0.001). Two-year recurrence rate was higher in patients with infection (infection: 30% versus control: 4%; p = 0.001). CONCLUSIONS Intra-abdominal infection increases IL-6 and VEGF after surgery for colorectal cancer. Amplification of inflammation and angiogenesis might be one of the mechanisms responsible for the higher recurrence rate observed in patients with anastomotic leakage or intra-abdominal abscess.

Abstract
OBJECTIVE To describe the clinical impact of PET/CT in the management of patients with vulvar cancer. MATERIAL AND METHODS Retrospective analysis of 13 PET/CT studies with (18)F-FDG (6 staging and 7 suspected recurrence) corresponding to 10 patients diagnosed with vulvar cancer by biopsy, with a mean age of 64.5 years. The preoperative PET/CT study was analyzed qualitatively according to the lesion region. Surgical excision was carried out, covering all the suspected areas according to the PET/CT study. This was compared with the histopathologic analysis. RESULTS Abnormal vulvar PET/CT uptake was found in 9 out of the 13 studies and invasion of adjacent structures in 5 of them (urethra, perineal, vagina). The inguinal-femoral lymph nodes were considered as affected in 3 studies and one pelvic lymph node was also affected. Four of the studies had extralymphatic involvement: 3 in lung and 1 in ischiorectal fossa. The PET/CT showed a 100% sensitivity for the detection of the vulvar lesion in squamous cell carcinomas and 60% in non-squamous cell ones. There was a false positive result for local invasion due to urine contamination. One of the studies with lung metastases was related to a synchronous breast tumor. All the pathological lymph node levels detected in the PET/CT study were confirmed in the histopathology study. No new lesions were identified by surgery. PET/CT changed the therapeutic management in 8/13 studies (61.5%). CONCLUSIONS PET/CT is postulated as a useful imaging test for the management of vulvar cancer, mainly in the identification of nodal metastases. It may affect both surgical planning and clinical management. Larger series are needed to confirm our findings.
