Computing spatio-textual affinities inside twitting in between a couple of metropolitan metropolises.
In contrast, rats with high cognitive competence were resilient to the negative effects of the forced swim test, irrespective of the spatial memory task used. These results point to a nonlinear relationship between spatial memory performance and behavioral despair, suggesting that different types of cognitive functioning may have differential effects on affective processes. BACKGROUND It is controversial whether peripheral arterial cannulation may achieve better results than direct aortic cannulation during surgery for Stanford type A aortic dissection (TAAD). METHODS Three-hundred and nine consecutive patients underwent surgical repair for acute TAAD from January 2005 to December 2017 at the Helsinki University Hospital, Finland. The early outcomes of patients who underwent surgery with direct aortic cannulation were compared with those in whom peripheral arterial cannulation was employed. RESULTS Direct aortic cannulation was employed in 80 patients and peripheral arterial cannulation in 229 patients. Patients who underwent surgery with direct aortic cannulation had hospital mortality (13.8% vs. 13.5%, p=0.962) and stroke/global brain ischemia (22.3% vs. 25.0%, p=0.617) similar to those with peripheral arterial cannulation. The other secondary outcomes were equally distributed between the unmatched study cohorts. Among 74 propensity score matched pairs, direct aortic cannulation had hospital mortality (12.2% vs. 9.5%, p=0.804) and stroke/global brain ischemia rates (21.6% vs. selleck compound 21.6%, p=1.000) comparable to peripheral arterial cannulation. The composite outcome of hospital mortality/stroke/global brain ischemia (29.7% vs. 27.0%, p=0.855), multiple stroke (16.2% vs. 17.6%, p=1.000), renal replacement therapy (11.8% vs. 13.0%, p=1.000) and length of stay in the intensive care unit (mean, 4.9±4.5 vs. 4.8±4.9 days, p=0.943) were also equally distributed between these matched cohorts. CONCLUSIONS In this institutional series, central arterial cannulation allowed a straightforward surgical repair of TAAD and achieved similar early outcomes to those of peripheral arterial cannulation. BACKGROUND Postoperative atrial fibrillation (POAF) is a common complication following coronary artery bypass graft surgery (CABG) and is associated with increased short and long-term mortality. While the precise etiology of POAF remains unclear, inflammation is a known contributing factor. Preliminary studies have suggested that an elevated preoperative platelet-to-lymphocyte ratio (PLR), an inexpensive and readily available novel inflammatory biomarker, may be associated with increased incidence of POAF following CABG. This study sought to further investigate this hypothesis. METHODS The study cohort included all patients undergoing isolated CABG, with no prior history of arrhythmia, who were operated on between August 1, 2010 and December 31, 2018 at a major Australian tertiary center (n=1,457). Patients were divided into the 'low' ( less then 86) or 'high' (≥86) PLR group based on an optimal cut-off derived from receiver operating curve analysis. The incidence of POAF was then compared. Categorical variables were analyzed using the chi-squared test and continuous variables using logistic regression. RESULTS Of 1,457 patients, 495 (34.0%) developed POAF. There was no statistically significant difference in the incidence of POAF between patients in the high and low PLR groups (34.8% vs 31.0%, p=0.22). Using multivariable logistic regression analysis, high PLR was not independently associated with POAF (OR 1.04, p=0.78). CONCLUSIONS Elevated preoperative PLR is not independently associated with POAF in patients undergoing isolated CABG. The findings of this study differ from those of two previous smaller studies. BACKGROUND There exists a knowledge gap regarding the safety of training in cardiac surgery. The purpose of this analysis was to establish the safety of resident training in cardiac surgery and compare the results of the trainee cases to those performed by consultants. METHODS 5894 (trainee=3343 vs consultant=2551) major cardiac operations (EuroSCORE 30 days (trainee; 4.2% versus consultant; 9.9%, p=0.001). CONCLUSIONS Resident training is safe in cardiac surgery without compromising the quality of patient care. In OECD guideline 443 - Extended One Generation Reproductive Toxicity Study (EOGRTS) - to be used for testing industrial and agrochemicals, it has been indicated that careful consideration of benefits and disadvantages should be made prior to conducting direct-dosing studies in nursing pups. Nursing pups will not be directly dosed in dietary and drinking water studies whereas in oral gavage studies this possibility exists. Besides the risk of intubation trauma and overdosing due to direct exposure and exposure via the mother's milk, direct dosing could lead to a different hazard assessment of chemicals depending on the choice of the route of administration. In addition, in case of industrial and agrochemicals used in industrial or professional settings only, there will never be direct exposure of newborns. Moreover, direct dosing of nursing pups is an artificial, non-physiological, route of exposure and as such it would hamper risk assessment. It should therefore only be considered in exceptional cases and justified on a case-by-case approach. ETHNOPHARMACOLOGICAL RELEVANCE Rheumatoid arthritis is a chronic inflammatory disease of joints. Dysoxylum binectariferum Hook.f (Family Meliaceae) is a Indian medicinal plant which is traditionally being used to heal inflammation of joints. AIM OF THE STUDY This work was aimed to carry out chemical standardization, in-vitro/in-vivo validation, oral pharmacokinetics and formulation development of anti-arthritic botanical lead, the rohitukine-enriched fraction of D. binectariferum. MATERIALS AND METHODS The rohitukine-enriched fraction of D. binectariferum was standardized using four chemical markers and was checked for microbial load, heavy metal content, aflatoxins and pesticides. Its in-vitro inhibitory effect on the lipopolysaccharide (LPS) induced production of pro-inflammatory cytokines TNF-α and IL-6 was studied in THP-1 cells. The in-vivo anti-arthritic activity was investigated in collagen-induced arthritis model in DBA/1J mice. The sustained release capsule formulation was developed and characterized for physicochemical and pharmacokinetic properties.
