707; 95% CI 1.062-6.902; P=0.037 in frozen section; OR=3.072; 95% CI 1.248-7.560; P=0.015 in paraffin section). The sensitivity, specificity, false-negative rate, false-positive rate, accuracy rate, and Kappa value of pretracheal-laryngeal LNM in frozen sections for predicting pretracheal-laryngeal LNM were 87.72%, 100%, 12.28%, 0%, 97.11% and 0.916 respectively, while those for predicting contralateral paratracheal LNM were 85,29%, 89.90%, 14.71%, 10.10%, 89.22%, and 0.618 respectively.

Pretracheal-laryngeal LNs in frozen section accurately predicted contralateral paratracheal LNM, which could allow the identification of patients who can benefit from an extended central LND.

Evidence on the effect of non-steroidal anti-inflammatory drugs (NSAIDs) on anastomotic leak (AL) rate after colorectal surgery is conflicting. Effects of NSAIDs might depend on the underlying disease. This meta-analysis aimed to review the effect of NSAIDs on AL rate in a homogeneous colorectal cancer patient population.

A systematic literature search using MEDLINE and EMBASE database was performed for studies with AL as primary outcome comparing NSAID use in the early postoperative phase with no NSAID administration in colorectal cancer patients undergoing surgical resection.

Nine studies including 10,868 patients met the inclusion criteria. this website The majority, 7689 patients (70.7%) underwent low anterior resection and 3050 patients (28.1%) underwent colonic resection. The pooled incidence of AL was 8.6% (95%CI 7.0-10.0). Overall AL rate after colorectal cancer surgery was not increased in patients using NSAIDs for postoperative analgesia compared to non-users (p=0.34, RR 1.23; 95%CI 0.81-1.86). This effect remained non-significant after stratification for low anterior resections (p=0.07). Stratification for colonic resections could not be performed because AL results for this subgroup were not reported separately. Neither non-selective NSAID use nor COX-2 selective NSAID use caused an increased AL rate (p=0.19, p=0.26). The results were robust throughout sensitivity analyses.

Use of NSAIDs in cohorts with patients undergoing surgical resection for colorectal cancer does not increase overall AL rate. Since results were robust throughout several subgroup and sensitivity analyses, prescription of NSAIDs after colorectal cancer surgery seems safe.

High plasma levels of the omega-3 fatty acids eicosapentaenoic acid (EPA), docosahexaenoic acid, and docosapentaenoic acid associates with positive outcomes in adult renal transplant recipients. However, data from pediatric populations are scarce. The aim of the study was to assess the fatty acid profile in a pediatric renal transplantation cohort and to examine the associations between plasma omega-3 fatty acids and cardiovascular disease (CVD) risk factors.

In this cross-sectional study comprising 53 children (median age, 12.2years; 32 boys) with a renal transplant, we assessed the prevalence of CVD risk factors as well as markers of end organ damage carotid intima-media thickness (cIMT) and left ventricular mass index. The associations between plasma omega-3 fatty acids and CVD risk factors were assessed.

Twenty-five (47%) patients were preemptively transplanted. Seventy-six percent had dyslipidemia and 51% had hypertension. The mean left ventricular mass index was 40.4±14.3g/m

, and 14% had left ventricular hypertrophy. The mean cIMT was 0.41±0.04mm. In a multivariate linear regression, EPA levels were inversely associated to blood pressure (β coeff.=-0.37, P=.007), triglycerides (β coeff.=-0.44, P=.01), and high-density lipoprotein cholesterol (β coeff.=-0.41, P=.01).

EPA levels are inversely associated with components of the metabolic syndrome, which may provide support for specific dietary advice or supplementation in this patient population. cIMT is less pronounced in our cohort than in comparable cohorts with lower rate of preemptive transplantations. Our results need replication in prospective cohorts.

Thus, understanding how cholesterol spontaneously self assembles into metastable structures that evolve into flat plate cholesterol crystals (CCs) in atherosclerotic plaque, and why they fundamentally change the nature of the disease provides a paradigm for the development of additional therapies. Specifically, flat plate CCs that form within lysosomes of macrophages may become large enough to disrupt lysosomal membranes leading to the release of cathepsin B and CCs fragments directly into the cytosol. In the cytosol, the surface of flat plate CCs can be recognized by complosome that together with cathepsin B may trigger pyrin domain-containing inflammasome. In addition, flat plate CCs in the cytosol may trigger caspase 8 initiating apoptosis. In the interstitial space, the surface of flat plate CCs can be recognized by complement and receptors on proinflammatory cells, and larger fragments can induce "frustrated phagocytosis" that together perpetuate inflammatory injury. In addition, rapid transition of metastable CCs into large flat plate CCs within lipid rich plaques can lead to traumatic injury by expansion of the plaque's necrotic core causing plaque disruption or rupture that may precipitate further inflammation. Other crystalloids in plaque including monosodium urate and calcium phosphate crystals can augment these processes. Thus, therapies that further limit the deposition of cholesterol in the vascular bed, slow the formation of flat plate CCs and inhibit crystal-induced inflammation may lead to further reduce CV risk in patients with established CV disease.
