Blood glucose level on postoperative day 1 is predictive of adverse outcomes after cardiovascular surgery.

AIM: Hyperglycaemia is now a recognized predictive factor of morbidity and mortality after coronary artery bypass grafting (CABG). For this reason, we aimed to evaluate the postoperative management of glucose control in patients undergoing cardiovascular surgery, and to assess the impact of glucose levels on in-hospital mortality and morbidity. METHODS: This was a retrospective study investigating the association between postoperative blood glucose and outcomes, including death, post-surgical complications, and length of stay in the intensive care unit (ICU) and in hospital. RESULTS: A total of 642 consecutive patients were enrolled into the study after cardiovascular surgery (CABG, carotid endarterectomy and bypass in the lower limbs). Patients' mean age was 68+/-10 years, and 74% were male. In-hospital mortality was 5% in diabetic patients vs 2% in non-diabetic patients (OR: 1.66, P=0.076). Having blood glucose levels in the upper quartile range (> or =8.8 mmol/L) on postoperative day 1 was independently associated with death (OR: 10.16, P=0.0002), infectious complications (OR: 1.76, P=0.04) and prolonged ICU stay (OR: 3.10, P<0.0001). Patients presenting with three or more hypoglycaemic episodes (<4.1 mmol/L) had increased rates of mortality (OR: 9.08, P<0.0001) and complications (OR: 8.57, P<0.0001). CONCLUSION: Glucose levels greater than 8.8 mmol/L on postoperative day 1 and having three or more hypoglycaemic episodes in the postoperative period were predictive of mortality and morbidity among patients undergoing cardiovascular surgery. This suggests that a multidisciplinary approach may be able to achieve better postoperative blood glucose control.

A morphological grading of spinal stenosis: a radiological study on LSS and LBP patients : P173

Introduction: Clinical symptoms and degree of spinal stenosis based on cross sectional dural sac area correlate only weakly in lumbar spinal stenosis (LSS) patients. We conceived a four grade classification system (A, B, C & D) based on the morphology of the dural sac and its contents as seen on T2 axial MRI images. The categories take into account the rootlet/CSF ratio. We applied this grading to three patient groups: LSS scheduled for surgery; LSS following conservative treatment and patients with low back pain (LBP) without leg pain. Materials/Methods: A total of 346 T2 axial MRI images taken from LSS and LBP patients were included in this retroperspective study. 37 patients had decompressive surgery (132 MRI images), 31 conservative treatment (116 MRI images) and 27 patients had unspecific LBP (98 MRI images). Dural sac cross-sectional surface area and morphological grading of the canal were measured digitally both at disc and pedicle level. Intra- and inter-observer reliability were assessed (weighted Cohen's kappa statistics) from 50 MRI images taken from the surgery group. Results: At the most severe disc level, grade A (mild stenosis) was found in 3% of MRI images of the surgical group as opposed to 51% in the conservatively treated group and 85% in the LBP group. Grade B occurred in 8% of the surgical, 20% of the conservative and was negligible in LBP group (below 1%). Grade C and D (severe stenosis) was found in 89% of the surgical group, as opposed to 30% in conservative group and 11% in LBP group. The grades of all groups were comparable at the pedicle levels, exhibiting in 94% a grade A with a maximum at the A1 grade. Pedicle and disc level cross-sectional area were smallest in the surgery group and smaller in the conservative group as compared to the LBP group at the levels L2, L3 and L4. According to cross-sectional area measurements patients from the surgery group seems to have smaller vertebral canal although this was not related to smaller stature. Validation of grading: Average intra-and inter observer kappas were 0.76 and 0.69 respectively, for physicians working in the study originating institution. Combining all observers the kappa values were 0.57 +/- 0.19. and 0.44 +/- 0.19 respectively. Dural sac cross-sectional area measurements showed no statistically significant differences between observers. Conclusion: Since no specific measurement tools are needed the grading suits everyday clinical practice and favours communication of degree of stenosis between practising physicians. In our institution Grade A stenosis was less likely to require surgical treatment. This grading can therefore be an aid in surgical patient selection in teaching units.

Poverty and Transitions in Health

Being objectively low income leads to poor health and a shorter life. But poverty can also be a matter of subjectively feeling poor. WZB economist Maja Adena and her colleague Michal Myck (DIW Berlin and the Center for Economic Analysis, CenEA, Szczecin) have substantiated how the subjective assessment of being poor affects the health of the 50+ age group.

Variability and genetic differentiation among Anopheles (Ano.) intermedius Chagas, 1908 and Anopheles (Ano.) mattogrossensis Lutz & Neiva, 1911 (Diptera: Culicidae) from the Brazilian Amazon

Anopheles (Anopheles) intermedius and Anopheles (Ano.) mattogrossensis are Brazilian anopheline species belonging to the scarcely studied Anopheles subgenus. Few studies have been done on the genetic differentiation of these species. Both species have been found infected by Plasmodium and are sympatric with other anopheline species from the Nyssorhynchus subgenus. Eighteen enzymatic loci were analyzed in larval specimens of An. intermedius and An. mattogrossensis aiming to estimate the variability and genetic differentiation between these species. An. mattogrossensis population showed higher genetic variability (P = 44.4 and Ho = 0.081 ± 0.031) than that of An. intermedius (P = 33.3 and Ho = 0.048 ± 0.021). Most analyzed loci showed genotypic frequencies according to Hardy-Weinberg equilibrium, except for LAP1 and LAP2 in An. intermedius, and EST1 and PGM loci in An. mattogrossensis. The genetic distance between these species (D = 0.683) was consistent with the inter-specific values reported for Anopheles subgenus. We verified that the polymorphism and heterozygosity percentile values found in both species and compared to those in the literature, showed no relation between the level of isozyme variability and geographical distribution. The low variability found in these two species is probably more related to the niche they occupy than to their geographic distribution.

Uncertainty about the true source. A note on the likelihood ratio at the activity level.

This paper focuses on likelihood ratio based evaluations of fibre evidence in cases in which there is uncertainty about whether or not the reference item available for analysis - that is, an item typically taken from the suspect or seized at his home - is the item actually worn at the time of the offence. A likelihood ratio approach is proposed that, for situations in which certain categorical assumptions can be made about additionally introduced parameters, converges to formula described in existing literature. The properties of the proposed likelihood ratio approach are analysed through sensitivity analyses and discussed with respect to possible argumentative implications that arise in practice.

Addressing High Level ICT Skills Recruitment Needs

Ireland is a successful major centre for ICT operations with ten of the top ICT companies in the world having substantial operations here. The large talent pool of ICT professionals that exists here is valuable both for foreign-owned and Irish companies. The cluster of internationally renowned firms and Irish companies offer a range of attractive career opportunities for professionals. A range of skills recruitment difficulties have been raised through the work of the Expert Group on Future Skills Needs (EGFSN), specifically the immediate issue of high-level ICT skills within both the ICT sector and from other sectors such as international financial services, banking and business services. Forfs, with the support of IDA Ireland and Enterprise Ireland, engaged in discussions with a selected range of foreign–owned and Irish companies employing approximately 30,000 employees to establish the nature of positions involved, the reasons for recruitment difficulties and to identify measures to help address them. Consultations were also held with key stakeholders including IDA Ireland, Enterprise Ireland, ICT Ireland, Software Ireland, IT@Cork, Engineers Ireland and Dublin Chambers of Commerce. Discussions were held with the heads of the computing departments of all Universities and Institutes of Technology at a meeting chaired by the Higher Education Authority. An in-depth analysis of third-level ICT supply statistics and trends was undertaken to inform the research.

ICT Action Plan Meeting the high-level skills needs of enterprise in Ireland

The technology sector in Ireland is thriving. Employment, through indigenous and multinational technology firms continues to grow strongly year on year. All of the top 10 multinational technology companies have a significant presence in Ireland and the indigenous software sector’s exports are worth well in excess of €1 billion annually. Five of the top 10 exporters in Ireland are technology companies, and the sector is responsible for approximately one-third of Ireland’s total turnover. Since January 2011, over 80 jobs a week have been announced in the sector. This is on foot of 6% employment growth in 2009 and 4% in 2010. A recent global competitiveness report ranks Ireland as the top destination in the world by quality and value of investments. With a growing multinational technology presence in Ireland and a vibrant and innovative indigenous software sector, the future prospects for Ireland’s technology sector are bright.

Naming the Reformed Junior Cycle Proposals for the Minister for Education and Skills - Irish Second Level Students Union (ISSU)

It was important to us to engage with as many students as possible throughout the process of developing a new name for the reformed junior cycle. In this vein, we used a wide variety of methods to engage with students in order to capture as many ideas as possible; text messaging, Facebook, Twitter, email and consultation sessions. We circulated posters to all schools via post and/or email, and contacted schools in catchment areas for the consultation sessions by phone. In our consultation sessions, we had discussions with the participating students about what the new junior cycle would be, closely guided by the content of “Towards a Framework for Junior Cycle” from the National Council for Curriculum and assessment. In these sessions, students then gave feedback on what they thought of the reformed junior cycle, developed their own ideas, and identified what they thought should be reflected in the name of the reformed junior cycle

Representing diffusion MRI in 5D for segmentation of white matter tracts with a level set method.

We present a method for segmenting white matter tracts from high angular resolution diffusion MR. images by representing the data in a 5 dimensional space of position and orientation. Whereas crossing fiber tracts cannot be separated in 3D position space, they clearly disentangle in 5D position-orientation space. The segmentation is done using a 5D level set method applied to hyper-surfaces evolving in 5D position-orientation space. In this paper we present a methodology for constructing the position-orientation space. We then show how to implement the standard level set method in such a non-Euclidean high dimensional space. The level set theory is basically defined for N-dimensions but there are several practical implementation details to consider, such as mean curvature. Finally, we will show results from a synthetic model and a few preliminary results on real data of a human brain acquired by high angular resolution diffusion MRI.
