Abstract
Background In the last decades, non-standard employment has grown globally. Especially for own account workers (OAW), this implies the self-management of economic, health and other work-related risks. In the context of COVID19, this management was stressed by lockdowns and the novel health risks imposed by an unknown and highly contagious virus, demanding the incorporation of new knowledge and preventive actions. As part of a six-country multiple case qualitative study on non-standard workers (NSW), we explore their experiences and strategies deployed to protect their health while continuing to work. Methods We performed 40 in-depth interviews to NSWs between October 2020 and February 2021, identified through the PWR online-survey and selected through an intentional sampling strategy according to levels of precarity (high-low), gender (male/female) and age (18-39/40-55). Interviews were analysed through abductive thematic analysis. Results We observed a significant transfer to platform, Uber-like jobs in the delivery of goods during lockdown (n = 7). In the absence of institutional prevention programs and provision of protective equipment, OAWs (n = 13) refer the self-provision of COVID19 prevention to protect themselves and their families while continuing to work, deploying a series of strategies amidst limited understanding of both mode of transmission of the virus and actual effective preventive measures. This had serious consequences for them and their families, expressed in anguish, sense of lack of control, fear, and fragility in the face of a major health risk given their constant potential exposure to the virus, leading to both physical and mental health problems, as well as COVID19 infection. Conclusions The substantial growth worldwide of gig delivery work during lockdowns magnified a pressing public health problem, critically requiring social security for gig and OAWs and the development of more equitable and accessible occupational health for all. Key messages • Substantial growth worldwide of gig delivery work during lockdowns magnified a pressing public health problem. • Social security for gig and OAWs are critically required as well as the development of more equitable and accessible occupational health for all.

Abstract
Abstract
Introduction
Aortic stenosis (AS) is the most common heart valve disease and it is strongly prevalent with elderly. AS is a progressive, degenerative disease associated with fibrosis and calcification of the valve leaflets. Surgical valve replacement is the only treatment available. Molecular, cellular and interstitial events activate multifactorial and complex cues with a significant contribution by valve interstitial cells (VICs). Despite male sex is a risk factor for developing AS, there is scant information on sex-specific differences in aortic valve (AV) biology or pathology.
Purpose
The aim of our study was to analyse sex-specific differences in aortic valves from AS patients.
Methods
185 patients with severe AS undergoing surgical valve replacement were recruited. 149 AVs (66 women; 83 men) were used for ex vivo analyses. Human VICs were isolated from 36 AVs (12 women; 24 men) for in vitro experiments. AVs structure were evaluated by haematoxylin-eosin, Movat, Alizarin Red, Congo red and Alcian blue/Sirius Red staining and immunohistochemistry. Western blot, ELISA and zymography were used for molecular biology studies.
Results
AVs from men presented increased inflammatory infiltrates (CD68 and CD45 positive cells) as compared to women. Complementarily, AVs from men exhibited higher levels of the inflammatory molecules interleukin (IL)-6 and IL-1b and RANTES. In line with these results, oxidative stress markers (eNOS, myeloperoxidase, malondialdehyde and nitrotyrosine) were upregulated in male AVs. Concerning, fibrosis, increased levels of collagen type I, fibronectin and syndecan-1 were found in AVs from men. Extracellular matrix (ECM) remodelling was characterized by reduced metalloproteinase-1 expression and increased tissue inhibitor of metalloproteinase-2 expression in male AVs. Importantly, calcification and osteogenic markers (bone morphogenetic protein-9, periostin, osteocalcin and Sox-9) was greatly enhanced in men AVs as compared to women. These findings were confirmed in isolated VICs. At baseline, male VICs presented higher myofibroblast-like phenotype than female VICs. In line with our ex vivo results, male VICs exhibited increased inflammatory, oxidative stress, fibrotic and osteogenic differentiation markers.
Conclusions
Our results suggest that the mechanisms driving the AV pathogenesis could be different in men and women patients with the same AS severity. Male AVs and isolated VICs presented more inflammation, oxidative stress, fibrosis and ECM remodelling including extensive calcification as compared to female. A better knowledge of the pathophysiological pathways in AVs and VICs will allow developing sex-specific options for AS treatment.

Abstract
People with weakened immune systems are at risk of developing candidiasis which is a fungal infection caused by several species of Candida genus. In this work, polymeric nanoparticles containing miconazole nitrate and the anesthetic lidocaine clorhydrate were developed. Miconazole was chosen as a typical drug to treat buccopharyngeal candidiasis whereas lidocaine may be useful in the management of the pain burning, and pruritus caused by the infection. Nanoparticles were synthesized using chitosan and gelatin at different ratios ranging from 10:90 to 90:10. The nano-systems presented nanometric size (between 80 and 300 nm in water; with polydispersion index ranging from 0.120 to 0.596), and positive Z potential (between 20.11 and 37.12 mV). The determined encapsulation efficiency ranges from 65 to 99% or 34 to 91% for miconazole nitrate and lidocaine clorhydrate, respectively. X-ray diffraction and DSC analysis suggested that both drugs were in amorphous state in the nanoparticles. Finally, the systems fitted best the Korsmeyer-Peppas model showing that the release from the nanoparticles was through diffusion allowing a sustained release of both drugs and prolonged the activity of miconazole nitrate over time against Candida albicans for at least 24 h.

Abstract
La Société de réanimation de langue française et la Société française de médecine d’urgence ont décidé d’élaborer de nouvelles recommandations sur la prise en charge de l’état mal épileptique (EME) avec l’ambition de répondre le plus possible aux nombreuses questions pratiques que soulèvent les EME : diagnostic, enquête étiologique, traitement non spécifique et spécifique. Vingt-cinq experts ont analysé la littérature scientifique et formulé des recommandations selon la méthodologie GRADE. Les experts se sont accordés sur 96 recommandations. Les recommandations avec le niveau de preuve le plus fort ne concernent que l’EME tonico-clonique généralisé (EMTCG) : l’usage des benzodiazépines en première ligne (clonazépam en intraveineux direct ou midazolam en intramusculaire) est recommandé, répété 5 min après la première injection (à l’exception du midazolam) en cas de persistance clinique. En cas de persistance 5 min après cette seconde injection, il est proposé d’administrer la seconde ligne thérapeutique : valproate de sodium, (fos-)phénytoïne, phénobarbital ou lévétiracétam. La persistance avérée de convulsions 30 min après le début de l’administration du traitement de deuxième ligne signe l’EMETCG réfractaire. Il est alors proposé de recourir à un coma thérapeutique au moyen d’un agent anesthésique intraveineux de type midazolam ou propofol. Des recommandations spécifiques à l’enfant et aux autres EME sont aussi énoncées.

Abstract
Abstract
Aims
The Acute Cardiac Care Association (ACCA)–European Association of Percutaneous Coronary Intervention (EAPCI) Registry on ST-elevation myocardial infarction (STEMI) of the EurObservational programme (EORP) of the European Society of Cardiology (ESC) registry aimed to determine the current state of the use of reperfusion therapy in ESC member and ESC affiliated countries and the adherence to ESC STEMI guidelines in patients with STEMI.
Methods and results
Between 1 January 2015 and 31 March 2018, a total of 11 462 patients admitted with an initial diagnosis of STEMI according to the 2012 ESC STEMI guidelines were enrolled. Individual patient data were collected across 196 centres and 29 countries. Among the centres, there were 136 percutaneous coronary intervention centres and 91 with cardiac surgery on-site. The majority of centres (129/196) were part of a STEMI network. The main objective of this study was to describe the demographic, clinical, and angiographic characteristics of patients with STEMI. Other objectives include to assess management patterns and in particular the current use of reperfusion therapies and to evaluate how recommendations of most recent STEMI European guidelines regarding reperfusion therapies and adjunctive pharmacological and non-pharmacological treatments are adopted in clinical practice and how their application can impact on patients’ outcomes. Patients will be followed for 1 year after admission.
Conclusion
The ESC ACCA-EAPCI EORP ACS STEMI registry is an international registry of care and outcomes of patients hospitalized with STEMI. It will provide insights into the contemporary patient profile, management patterns, and 1-year outcome of patients with STEMI.

Abstract
It is very uncommon for urothelial carcinoma to develop in an ureterocele. It is generally discovered in an imaging study or in connection with haematuria. We found very few reports in the literature. Here, we report on the case of a 71-year-old male who initially presented with haematuria and low back pain and who then underwent transurethral resection for an intraureterocele tumour. Pathology confirmed urothelial carcinoma.

Abstract
BACKGROUND AND OBJECTIVE Parapneumonic empyema (PPE) is a frequent complication of acute bacterial pneumonia in children. There is limited evidence regarding the optimal treatment of this condition. The aim of this study was to compare the efficacy of drainage plus urokinase versus video-assisted thoracoscopic surgery in the treatment of PPE in childhood. METHODS This prospective, randomized, multicenter clinical trial enrolled patients aged <15 years and hospitalized with septated PPE. Study patients were randomized to receive urokinase or thoracoscopy. The main outcome variable was the length of hospital stay after treatment. The secondary outcomes were total length of hospital stay, number of days with the chest drain, number of days with fever, and treatment failures. The trial was approved by the ethics committees of all the participating hospitals. RESULTS A total of 103 patients were randomized to treatment and analyzed; 53 were treated with thoracoscopy and 50 with urokinase. There were no differences in demographic characteristics or in the main baseline characteristics between the 2 groups. No statistically significant differences were found between thoracoscopy and urokinase in the median postoperative stay (10 vs 9 days), median hospital stay (14 vs 13 days), or days febrile after treatment (4 vs 6 days). A second intervention was required in 15% of children in the thoracoscopy group versus 10% in the urokinase group (P = .47). CONCLUSIONS Drainage plus urokinase instillation is as effective as video-assisted thoracoscopic surgery as first-line treatment of septated PPE in children.

Abstract
Eleven susceptibility loci for late-onset Alzheimer's disease (LOAD) were identified by previous studies; however, a large portion of the genetic risk for this disease remains unexplained. We conducted a large, two-stage meta-analysis of genome-wide association studies (GWAS) in individuals of European ancestry. In stage 1, we used genotyped and imputed data (7,055,881 SNPs) to perform meta-analysis on 4 previously published GWAS data sets consisting of 17,008 Alzheimer's disease cases and 37,154 controls. In stage 2, 11,632 SNPs were genotyped and tested for association in an independent set of 8,572 Alzheimer's disease cases and 11,312 controls. In addition to the APOE locus (encoding apolipoprotein E), 19 loci reached genome-wide significance (P < 5 × 10(-8)) in the combined stage 1 and stage 2 analysis, of which 11 are newly associated with Alzheimer's disease.

Abstract
BACKGROUND Tacrolimus (Tac) is mainly metabolized by cytochrome P450 3A isoenzymes. In a cohort of heart transplant recipients, we investigated the effect of CYP3A5, CYP3A4, and ABCB1/MDR1 polymorphisms on Tac dose requirements and the risk of developing new-onset diabetes after transplantation (NODAT). METHODS A total of 65 heart transplant recipients were genotyped for 3 single nucleotide polymorphisms (SNPs) in the CYP3A5 (SNP rs776746), CYP3A4 (SNP rs2740574), and ABCB1 (SNP rs104564). The mean Tac dose values were compared between the genotypes. RESULTS CYP3A5 3 homozygotes (nonexpressers; n = 55, 85%) received significantly higher Tac dose compared with CYP3A5 1 carriers (expressers). No different NODAT frequencies were found between the genotypes. CONCLUSIONS The CYP3A5 polymorphism was the main determinant of Tac dose requirements among heart transplant recipients. This common functional polymorphism had no influence on the risk of developing NODAT.

Abstract
In 2012, intramuscular midazolam appears as effective as intravenous lorezepam for the first line treatment of convulsive status epilepticus. Perampanel, a new anti-epileptic drug, will be soon available. Two oral treatments are now available for stroke prevention in atrial fibrillation setting. The methylphenidate and the Tai Chi could increase the walk capacity of patients suffering from Parkinson disease. A comprehensive cardiac work-up is essential for some congenital myopathy. A new drug against migraine seems free from vasoconstrictive effect. Antioxidants are harmful in Alzheimer disease. Some oral medication will be available for multiple sclerosis.

Abstract
Mutations in the SPG7 gene were initially reported in patients with autosomal recessive hereditary spastic paraplegia (HSP). Recent works suggested a dominant effect for some SPG7 mutations. To characterize the SPG7 mutational spectrum in a large cohort of Spanish HSP patients, we sequenced the whole SPG7 gene in a total of 285 Spastic Paraplegia patients. Large gene rearrangements were also ascertained in some patients. We found a total of 14 SPG7 mutations (12 new) in 14 patients; 2 were large deletions. All the mutation carriers had an adult onset age but only five (35%) had a complicated phenotype. We identified a single mutation in 13 patients. Familial analysis suggested a dominant inheritance for one (p.Leu78*) of these mutations. Carriers of the rare p.A510V variant were significantly more frequent in patients vs healthy controls (3% vs 1%), suggesting a pathogenic role for this SPG7 variant. We reported a high frequency of patients with only one SPG7 mutation, and a putative pathogenic role for the p.A510V variant.

Abstract
Mesenchymal stem cells have demonstrated their potentiality for therapeutic use in treating diseases or repairing damaged tissues. However, in some cases, the results of clinical trials have been disappointing or have not worked out as well as hoped. These disappointing results can be attributed to an inadequate or insufficient preclinical study. For medical and surgical purposes, the similarities between the anatomy of pig and human make this animal an attractive preclinical model. In this sense, for mesenchymal stem cell-based therapy, it is strongly necessary to have well characterized animal-derived mesenchymal stem cell lines to validate preclinical effectiveness of these cells. In this work, porcine mesenchymal stem cells (pMSCs) were isolated from bone marrow, adipose tissue and peripheral blood and compared in terms of differentiation potential, cell surface markers and gene expression. Our results demonstrated that the isolation and in vitro expansion protocols were feasible and effective. The data presented in this work are relevant because they provide an extensive phenotypic characterization; genetic study and differentiation behavior of the most commonly used stem cell lines for clinical practices. These pMSCs are widely available to scientists and could be a valuable tool to evaluate the safety and efficacy of adoptively transferred cells.

Abstract
Apolipoprotein E (APOE) dependent lifetime risks (LTRs) for Alzheimer Disease (AD) are currently not accurately known and odds ratios alone are insufficient to assess these risks. We calculated AD LTR in 7351 cases and 10 132 controls from Caucasian ancestry using Rochester (USA) incidence data. At the age of 85 the LTR of AD without reference to APOE genotype was 11% in males and 14% in females. At the same age, this risk ranged from 51% for APOE44 male carriers to 60% for APOE44 female carriers, and from 23% for APOE34 male carriers to 30% for APOE34 female carriers, consistent with semi-dominant inheritance of a moderately penetrant gene. Using PAQUID (France) incidence data, estimates were globally similar except that at age 85 the LTRs reached 68 and 35% for APOE 44 and APOE 34 female carriers, respectively. These risks are more similar to those of major genes in Mendelian diseases, such as BRCA1 in breast cancer, than those of low-risk common alleles identified by recent GWAS in complex diseases. In addition, stratification of our data by age groups clearly demonstrates that APOE4 is a risk factor not only for late-onset but for early-onset AD as well. Together, these results urge a reappraisal of the impact of APOE in Alzheimer disease.

Abstract
As the prevalence and severity of anthelmintic resistance continue to rise, nematode infections in sheep correspondingly reduce the profitability of the sheep industry. In Costa Rica, sheep production systems are increasing in both number and importance. A field trial study was carried out to detect the level of anthelmintic resistance to albendazole and ivermectin in gastrointestinal nematodes (GIN) of sheep from seven farms in Costa Rica. Resistance was determined using the fecal egg count reduction test (FECRT). Three treatment groups were assessed on each farm: control, albendazole, and ivermectin. Haemonchus spp. (71%), Strongyloides sp. (57%), and Trichostrongylus spp. (43%) presented resistance levels to albendazole, whereas Strongyloides sp. (43%), Haemonchus spp. (29%), and Trichostrongylus spp. (29%) were resistant to ivermectin. Haemonchus spp., Strongyloides sp., and Trichostrongylus spp. were the most resistant GIN to both products. This study suggests that frequency of treatment, exclusive chemical control, and visual estimation of animal weight to calculate dosage may contribute to the high levels of anthelmintic resistance that were observed on the farms analyzed herein.

Abstract
Laparoscopic colorectal surgery has well-known benefits. However, an abdominal incision, albeit much smaller than conventional surgery, is still needed. A transvaginal extraction of a sigmoid colon neoplasia with en bloc salpingo-oophorectomy and colorectal mechanical anastomosis is described. The technique is feasible and safe. The excellent recovery of the 86-year-old patient shows the potential future of the natural orifices endoscopic surgery.

Abstract
BACKGROUND A proposal to calculate and use the reference change value (RCV) as an objective guide for interpreting the numerical results obtained in clinical laboratory serial testing is introduced in this study. METHODS A database showing the results of a compilation of 191 publications on biological variation and including information on a number of analytes provided the standardized criterion based on biology for calculating the RCVs. RESULTS For each of the 261 analytes included in the study, the RCV was determined using Harris's formula, replacing analytical imprecision with the desirable specification of analytical quality based on half the within-subject biological variation at 95% probability levels. The result is a guide for a common criterion to identify clinically significant changes in serial results. CONCLUSIONS The RCV concept is an approach that can be offered by laboratories to assess changes in serial results. The RCV data in this study are presented as a point of departure for a widely applicable objective guide to interpret changes in serial results.

Abstract
Obesity is considered a chronic and epidemic illness, hece difficult to treat. As conservative treatment has a high rate of failure, and considering morbimortality and sequels of surgery, less invasive techniques appeared to contribute to the treatment of this illness. The most implanted technique nowadays is the Intragastric Balloon, considered more efficient as conservative treatments and with less risks tan surgery, but having today a lack of consensus on indications and few information on his limitations, while its apparition in medias promote an important expansion in the 4 last years. In this publication, we do a critical revision, and describe limitations of this treatment, based on the evidences given by literature. We conclude this revision with some recommendations concerning the technique and indications, material and human requiring, need of a Multidisciplinary Team, as well as an adequate control and following.

Abstract
The incidence of facial palsy is about 50/100000/year, i.e. 210 cases/year in Geneva. Clinicians can be puzzled by it, because it encompasses aetiologies with very diverse prognoses. Most patients suffer from Bell palsy that evolves favourably. Some, however, suffer from diseases such as meningitis, HIV infection, Lyme's disease, CVA, that require fast identification because of their severity and of the need for specific treatments. This article proposes an algorithm for pragmatic and evidence-based management of facial palsy.

Abstract
Background The H5N1 strain of avian influenza virus has been involved in severe mortality in domestic poultry, and has also been found in different species of wildlife in Europe. The Basque Country avian influenza surveillance program began sample collection and processing the fall of 2005. Results Here we report the first confirmation of the presence of highly pathogenic H5N1 strain in a Great Crested Grebe (Podiceps cristatus) found dead in a pond near Vitoria in the Basque Country on the North of Spain. Regarding the survey for generic influenza type A virus, we have obtained positive results in about 8% of more that 3500 birds examined. Conclusion We think that the self-limiting nature of our finding and others proves that certain regions have ecological, geographical and climatological features that make it difficult for the H5N1 virus to spread [1] and cause disease at least in the large scale scenario that has been worrying human and animal health authorities during the last years.

Abstract
Human infections by Pasteurella multocida are usually associated with bites or scratches from dogs and cats. Many of them are accompanied by other oropharyngeal microorganisms of these animals. We herein present a case of bacteremic meningitis by P. multocida in an 86-year-old woman who was living with seven cats. Even though no skin or soft tissue infection was recorded, it is possible that a mild infection had gone undetected and a subsequent bacteremia had impacted on the meninges, or that meningitis could have occurred after nasopharyngeal colonization (not demonstrated). The isolates obtained from blood cultures and cerebrospinal fluid were identified as P. multocida by API 20NE, API 20E, and Vitek 1. In agreement with findings in the literature, this strain was susceptible to penicillin, cefotaxime, levofloxacin and tetracyclines.

Abstract
OBJECTIVE the aim of the study was to assess the incidence, clinical presentation, location, and response to endoscopic therapy of gastrointestinal bleeding from Dieulafoy's lesion. MATERIAL AND METHOD ALL consecutive episodes of gastrointestinal bleeding due to Dieulafoy's lesion seen between 2000 and 2006 were retrospectively reviewed. All main clinical and endoscopic data were collected: type and effectiveness of endoscopic therapy, rebleeding, complications, and mortality during hospitalization. RESULTS WE found 41 patients, 26 males and 15 females, median age of 71.19 years. Dieulafoy's lesion accounted for 1.55% of all gastrointestinal bleeding episodes during the study period. The incidence of Dieulafoy's lesion was 2.2 cases/100.000 inhabitants/year. Active bleeding at endoscopy was present in 85.36%, and comorbidity in 92.68%. The stomach was the most frequent location (60.97%), followed by duodenum (29.26%). Endoscopic therapy achieved initial hemostasis in all cases. Three patients (7.31%) initially treated with epinephrine injection showed rebleeding and properly responded to a second session of endoscopic therapy. No surgery was needed. The mortality rate during hospitalization was 4.87%. CONCLUSIONS Dieulafoy's lesion is an uncommon, but potentially severe cause of gastrointestinal bleeding. It may be found in any location within the gastrointestinal tract. Endoscopic therapy is effective and safe. Injected epinephrine alone is associated with a higher risk of rebleeding.

Abstract
Control in vitro tick (Boophilus microplus; Acari: Ixodidae) through plant extracts. Hydro-alcohol extracts of ten tropical plants were tested by the immersion method on mature ticks (Boophilus microplus Canestrini 1887). The biological evaluation was made with raw hydro alcoholic extracts (R-OH) to determine the most promissory compounds, which later were fractioned in their polar and non-polar parts. The polar parts showed a significantly inferior effect. The species that produced the highest mortality were Zizigium aromaticum, Morus alba, Piper nigrum and the mixture of Allium sativum- Z. aromaticum (all non-polar); on oviposition: M. alba, P. nigrum and the mixture of A. sativum - Z. aromaticum (all non-polar); on eclosion: P. nigrum, Z. aromaticum, Echinacea angustiofilia, Poligonum punctatum, M. alba and the mixture of A. sativum-Z. aromaticum (all non-polar): on control percentage: P. nigrum, E. angustifolia, P. punctatum and M. alba (all non-polar, except for M. alba in which both fractions showed important activity); and finally, on the percentage of oviposition inhibition: P. nigrum, E. angustifolia, P. punctatum, Gliricidia sepium and M. alba.

Abstract
OBJECTIVE To investigate the association between four polymorphisms of the 5-HT(2A) receptor and 5-HT transporter genes and heroin dependence. METHODS 113 heroin- dependent patients (DSM-IV criteria) and 420 unrelated healthy controls from Asturias (Northern Spain) were genotyped using standard methods. RESULTS There was an apparent difference in the distribution of genotypes for A-1438G polymorphisms (p = 0.024, not significant after Bonferroni correction). The 5-HT(2A) -1438A allele was significantly more common in patients than controls [0.55 and 0.45, respectively; corrected p = 0.042, OR = 1.51 (95% CI = 1.13-2.03)]. An interaction was observed between A-1438G of 5-HT(2A) and 5-HTT polymorphisms. The association between the -1438AA vs. AG/GG genotypes and heroin dependence was enhanced in the presence of 12-repeat 5-HTT VNTR and short 5-HTTLPR alleles [24.8% in heroin-dependent patients vs. 12.6% in controls; corrected p = 0.045, OR = 2.28 (95% CI = 1.36-3.82)]. CONCLUSIONS Our findings support a contribution of the 5-HT(2A) gene to susceptibility to heroin dependence, as well as a possible synergistic effect of 5-HT(2A) and 5-HTT genes on susceptibility to heroin dependence.

Abstract
Our objective was to analyse the role of endothelin1 gene (EDN1) variation in essential left ventricular hypertrophy (LVH). We searched for EDN1 variants in 145 Spanish patients with an essential form of LVH (not secondary to hypertension, aortic stenosis, or any other disease that could explain the hypertrophy). The five EDN1 coding exons and 1.5 kilobases of the promoter region were analysed through single strand conformation analysis and direct sequencing. We found four nucleotide changes: -1224 C/A (promoter), -131 ins/del A (exon 1, 5'-non-translated sequence), A/G in codon 106 (exon 3, silent), and G/T in codon 198 (exon 5, lys198asn). To determine the association between these polymorphisms and cardiac hypertrophy, we compared the genotype frequencies from these 145 patients with 250 healthy controls. We found a higher frequency of patients homozygous for 198 lys (198 KK) (65% vs. 52%; p = 0.01; OR = 1.76) and for -1224 AA (73% vs. 66%; p = 0.19). Homozygotes for -1224 A + 198 K (AA+KK) were significantly more frequent in patients (62% vs. 45%; p = 0.0007; OR = 2.10; 95% CI = 1.35-3.25). The expression of the -1224 C/A and exon 5 K198N variants was analysed with cells in culture. These in vitro studies showed that these variations did not differ in their expression levels. In conclusion, our work has shown that EDN1 variation, and in particular homozygosity for the -1224A/198K haplotype, is associated with the risk of developing cardiac hypertrophy. However, these EDN1 variants do not affect in vitro gene expression.

Abstract
Cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy (CADASIL) is one of the most common hereditary forms of stroke, and migraine with aura, mood disorders, or dementia, are also frequently found in these patients. Missense mutations in the Notch3 gene that create or destroy cysteine residues, have been found in most cases with a family history of the disease, although a few sporadic cases harbouring Notch3 mutations have also been described. Here, we describe a 44-year-old patient with clinical features of CADASIL who was a carrier of a new Notch3 mutation: cys128-->gly. Both parents were alive and healthy, and negative for the mutation. This case illustrates the interest of analysing the Notch3 gene in cases with clinical features of CADASIL, even in the absence of a family history of the disease.

Abstract
Pathogenic mutations in the leucine-rich repeat kinase 2 gene (LRRK2; PARK8) have been implicated in autosomal dominant, late-onset parkinsonism. The LRRK2 6055G > A (G2019S) mutation is the most common reported to date, and has been observed in a number of different European populations. So far, only the LRRK2 4321C > G (R1441G) mutation has been identified in the Spanish population. Herein we have assessed the frequency of G2019S in a referral-based series of 225 patients with Parkinson's disease (PD) from the region of Asturias, Northern Spain. The mutant allele was identified in five (2.7%) of the sporadic late-onset patients and was not present in control subjects. All carriers displayed genetic profiles consistent with the same haplotype, as previously reported for Lrrk2 G2019S-positive subjects. None of these patients presented with a family history of parkinsonism at the time of diagnosis. Thus, approximately 5% of sporadic patients with PD from the North of Spain have either Lrrk2 G2019S or R1441G substitutions.

Abstract
A recent large-scale experimental study showed that bottle-feeding ovine colostrum from seropositive ewes results in high MVV-seroconversion in lambs. In contrast, relatively few lambs that naturally suckled colostrum from seropositive dams seroconverted as a result of it. Furthermore, lambs fed uninfected bovine colostrum readily seroconverted when mixed with ovine-colostrum lambs indicating that horizontal MVV transmission between lambs was efficient. MVV-infection was further investigated in the same samples using two PCR tests targeting sequences in the long-terminal repeats (LTR) and POL MVV genes. PCR-tests confirmed previous serological findings. However, the LTR-PCR was more sensitive and allowed detecting infection earlier than the other tests, including 5-8% of new-born lambs from seropositive dams, providing more evidence that prenatal MVV-infection may be more important than considered. The degree of agreement between PCR and antibody tests in individual samples was low up to 6 months of age and moderate at 10 months-old. Nine percent of lambs were always PCR-negative but seroconverted and 19% of lambs were PCR-positive at least once and did not seroconvert. However, seroconversion was associated with increasing number of times lambs were PCR-positive and ovine colostrum-fed lambs were more frequently PCR-positive than other lambs. The significance of these findings in terms of MVV-infection, epidemiology and control is discussed.

Abstract
A three year long experimental study was carried out to investigate horizontal MVV-infection by PCR and ELISA, in 191 one year-old latxa dairy-sheep raised in two separate groups under low and high MVV-infection pressure, respectively. Sheep originated from a previous MVV-transmission study in lambs and seroprevalence among one year-old sheep in both groups was 15% approximately. The high infection-pressure group (H-group) consisted of 147 replacement ewes that joined a milk-producing, housed dairy-flock with 42-66% MVV-seroprevalence and the low infection-pressure group (L-group) were castrated males raised in a separate shed. In contrast to results obtained when infection was investigated in lambs, the overall degree of agreement between ELISA and PCR results was very good and there was some indication that it increased further as sheep became older. MVV-prevalence did not change in the L-group and increased to 57% in three year-old sheep in the H-group (p<0.001). Random effects logistic regression confirmed seroconversion was significantly higher in the H-group compared to the L-group and was highest during the year after the sheep were introduced in the dairy flock and did not increase with age as in previous studies using less sensitive antibody assays. The evidence that horizontal transmission can be very low in spite of prolonged close contact between infected and non-infected sheep is valuable for MVV-control purposes. Furthermore it highlights the need to investigate virus excretion dynamics in infected animals and animal to animal transmission to improve our overall understanding of horizontal MVV transmission in MVV endemic populations.
