Abstract
Genetic architecture of sheep reproduction is increasingly gaining scientific interest due to the major impact on sheep production systems. In the present study, we conducted pedigree-based analyses and genome-wide association studies using the Illumina Ovine SNP50K BeadChip to explore the genetic mechanisms underlying the reproduction of the highly prolific Chios dairy sheep. First lambing age, total prolificacy and maternal lamb survival were selected as representative reproductive traits and estimated as significantly heritable (h2 = 0.07-0.21) with no evident genetic antagonism among traits. We identified novel genome-wide and suggestive significant single-nucleotide polymorphisms (SNPs) on chromosomes 2 and 12 associated with age at first lambing. The new variants detected on chromosome 2 span a region of 357.79 kb with high pairwise linkage disequilibrium estimates (r2 = 0.8-0.9). Functional annotation analysis revealed candidate genes, such as the collagen-type genes and the Myostatin gene, that participate in osteogenesis, myogenesis, skeletal and muscle mass development resembling the functionality of major genes affecting the ovulation rate and prolificacy. Additional functional enrichment analysis associated the collagen-type genes with multiple uterine-related disfunctions, such as cervical insufficiency, uterine prolapse and abnormalities of the uterine cervix. Several genes (e.g., KAZN, PRDM2, PDPN, LRRC28) localised close to the SNP marker on chromosome 12 were grouped in annotation enrichment clusters majorly involved in developmental and biosynthetic pathways, apoptosis, and nucleic acid-templated transcription. Our findings may further contribute to unravel the genomic regions that are important for sheep reproduction and could be incorporated into future selective breeding programmes.

Abstract
A 79-year-old male with a previous history of ischaemic heart disease and previous coronary artery bypass grafting (CABG) in 2005 presented with atypical chest pain. He also had past medical history of hypertension, hyperlipidaemia and bladder diverticulum which has been previously investigated by an abdominal CT. The latter had showed an incidental finding of what was reported to be a large pericardial cyst. Despite poor acoustic window, transthoracic echocardiography revealed a spherical echo–free structure in the area of the right atrioventricular groove (Figure 1, panel A white arrow). As the patient was too claustrophobic to undergo cardiac MRI, he was subsequently referred for a cardiac CT in order to further investigate the cystic mass and assess graft patency. The CT revealed an occluded left internal mammary artery (LIMA) to the LAD, severe left main (LM) and proximal LAD disease, a patent vein graft to an obtuse marginal (OM) branch and identified a largely thrombosed giant aneurysm (62x65x89 mm) of an otherwise patent vein graft to the RCA (Figure 1, panels B–E, white arrows point to the thrombosed and yellow arrows point to the non-thrombosed segments of the vein graft aneurysm). Coronary angiography confirmed occlusion of the LIMA, patency of the OM vein graft and identified only the non-thrombosed segment of the RCA vein graft aneurysm (Figure 1, panel F). The case was discussed at an MDT meeting and it was decided to proceed with LM and LAD stenting, and initially conservative management and close surveillance of the RCA vein graft aneurysm as the patient was high–risk for repeat CABG due to age, frailty and other comorbidities.

Abstract
Myeloid sarcoma (MS), previously known as granulocytic sarcoma, is a rare, localized, tumor mass composed of myeloid precursor cells, with or without maturation, and occurring at an anatomical site other than the bone marrow (BM). Chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), in contrast, is a B-cell hematological malignancy. We describe the first reported case of concurrent presentation of nodal MS and of BM CLL/SLL in the same patient. Fatal leukemic central nervous system infiltration was the final outcome. We provide possible explanations and investigate the pathophysiology of this unique, previously unreported co-morbidity.

Abstract
Background: Peripheral arterial disease (PAD) is frequently present in patients with acute ischemic stroke. However, there are limited data regarding the association between ankle brachial index (ABI) ≤ 0.90 (which is diagnostic of PAD) or > 1.40 (suggesting calcified arteries) and the severity of stroke and in-hospital outcome in this population. We aimed to evaluate these associations in patients with acute ischemic stroke. Patients and methods: We prospectively studied 342 consecutive patients admitted for acute ischemic stroke (37.4 % males, mean age 78.8 ± 6.4 years). The severity of stroke was assessed with the National Institutes of Health Stroke Scale (NIHSS)and the modified Rankin scale (mRS) at admission. The outcome was assessed with the mRS and dependency (mRS 2 - 5) at discharge and in-hospital mortality. Results: An ABI ≤ 0.90 was present in 24.6 % of the patients whereas 68.1 % had ABI 0.91 - 1.40 and 7.3 % had ABI > 1.40. At admission, the NIHSS score did not differ between the 3 groups (10.4 ± 10.6, 8.3 ± 9.3 and 9.3 ± 9.4, respectively). The mRS score was also comparable in the 3 groups (3.6 ± 1.7, 3.1 ± 1.8 and 3.5 ± 2.3, respectively). At discharge, the mRS score did not differ between the 3 groups (2.9 ± 2.2, 2.3 ± 2.1 and 2.7 ± 2.5, respectively) and dependency rates were also comparable (59.5, 47.6 and 53.3 %, respectively). In-hospital mortality was almost two-times higher in patients with ABI ≤ 0.90 than in patients with ABI 0.91 - 1.40 or > 1.40 but this difference was not significant (10.9, 6.6 and 6.3 %, respectively). Conclusions: An ABI ≤ 0.90 or > 1.40 does not appear to be associated with more severe stroke or worse in-hospital outcome in patients with acute ischemic stroke.

Abstract
AIM: To evaluate the association of nonalcoholic fatty liver disease (NAFLD) with acute ischemic stroke severity and in-hospital outcome.
METHODS: We prospectively studied all patients who were admitted in our Department with acute ischemic stroke between September 2010 and August 2012 (n = 415; 39.5% males, mean age 78.8 ± 6.6 years). The severity of stroke was assessed with the National Institutes of Health Stroke Scale (NIHSS) score at admission. NALFD was defined as serum alanine aminotransferase and/or aspartate aminotransferase levels above the upper limit of normal in the absence of other causes of elevated aminotransferases levels [chronic hepatitis B or C, drug toxicity, increased alcohol consumption (> 21 and > 14 drinks per week in men and women, respectively), cholestatic diseases or rhabdomyolysis]. The outcome was assessed with the modified Rankin scale (mRS) score at discharge and in-hospital mortality. Adverse outcome was defined as mRS score at discharge ≥ 2. Dependency at discharge was defined as mRS score between 2 to 5.
RESULTS: NAFLD was present in 7.7% of the study population. Patients with NAFLD had lower serum high-density lipoprotein cholesterol and higher triglyceride levels than patients without NAFLD (P < 0.05 for both comparisons). Demographic data, the prevalence of other cardiovascular risk factors and the prevalence of established CVD did not differ between the two groups. At admission, the NIHSS score did not differ between patients with and without NAFLD (6.3 ± 6.4 and 8.8 ± 9.6, respectively; P = NS). At discharge, the mRS score did not differ between the two groups (1.9 ± 2.2 and 2.6 ± 2.2 in patients with and without NAFLD, respectively; P = NS). Rates of dependency at discharge were also similar in patients with and without NAFLD (36.8% and 55.0%, respectively; P = NS) as were the rates of adverse outcome (42.9% and 58.6%, respectively; P = NS). In-hospital mortality rates also did not differ between the 2 groups (8.0% and 7.0% in patients with and without NAFLD, respectively; P = NS).
CONCLUSION: The presence of NAFLD in patients admitted for acute ischemic stroke does not appear to be associated with more severe stroke or with worse in-hospital outcome.
