Freshwater gammarids are known to colonise occasionally sinking-cave streams, providing contrasting morphological, life-history and ecophysiological adaptations compared to their surface conspecifics. In this study, a subterranean and a surface population of the species Gammarus balcanicus was surveyed for one year in a sinking-cave stream from the Western Carpathians (Romania). The results showed that the cave-dwelling population comprised individuals that were significantly larger compared to their surface conspecifics, had larger body-size at sexual maturity and that the females produced fewer, but larger eggs, compared to the population situated outside the cave. The trophic position and the omnivory were significantly higher for the cave-dwelling compared to surface population and the elemental imbalance for CP molar ratios lower, but similar for CN. However, the subterranean population did not present troglomorphic characters or longer lifespan as known for other cave-surface paired crustaceans. This, together with the rather extensive hydrological connection of the habitats, suggests active gene-flow between populations and similar response to seasonality for body-size distributions, indicating that the observed ecophysiological and life-history differences are rather the consequence of phenotypic plasticity than the result of genetic adaptation. Evolutionary teratology recognises certain anatomical modifications as developmental anomalies. Within non avian-theropod dinosaurs, the strong forelimb shortening of Tyrannosauridae, Carnotaurinae and Limusaurus - associated with a reduction or loss of autonomy - have been previously diagnosed as evolutionary anterior micromelias. The feature is here examined with Acrocanthosaurus atokensis (Carcharodontosauridae) and Gualicho shinyae (Neovenatoridae). The micromelic diagnosis is confirmed for Acrocanthosaurus, without supplementary malformations. Gualicho is considered as a borderline case, outside of the micromelic spectrum, but shows a total phalangeal loss on digit III. The reduction in the biomechanical range of Acrocanthosaurus' forelimbs was compensated by the skull and jaws as main predatory organs. The same is assumed for Gualicho, but its robust first digit and raptorial claw are to be underlined. Other gigantic-sized and derived representatives of Carcharodontosauridae probably shared the anterior micromelia condition, potentially due to developmental modifications involving differential forelimbs/hindlimbs embryological growth rates, secondarily associated with post-natal growth rates leading to large and gigantic sizes; a converging state with Tyrannosauridae. Nevertheless, whereas developmental growth rates are also considered in the shortened condition of Gualicho, there is no association with post-natal gigantism. Finally, the digit III reduction likely followed the same evolutionary pathways as Tyrannosauridae, potentially involving BMPs, Fgfs and Shh signalling. BACKGROUND In the midst of the international opioid-related overdose (OOD) crisis, appropriate naloxone training is needed by both healthcare professionals and community members to better leverage its life-saving potential. https://www.selleckchem.com/products/nedisertib.html OBJECTIVE Pilot the use of a virtual reality simulation for training student nurses to identify signs and symptoms of an OOD, properly administer intranasal naloxone, and provide immediate recovery care after revival. DESIGN This quasi-experimental pretest-posttest study evaluated knowledge and attitudes towards intervening during an opioid-related overdose among student nurses before and after participating in a traditional hybrid simulation or virtual reality simulation. SETTING A medium sized urban university's school of nursing in the Northeastern United States. PARTICIPANTS Fifty (N = 50) senior Bachelor of Nursing Science (BSN) students. METHODS Knowledge and attitudes were assessed using the Opioid Overdose Knowledge Scale (OOKS) and Opioid Overdose Attitudes Scale (OOAS). Students ant findings between training groups indicates that the mobile virtual reality training is comparable to the in-person hybrid simulation for training nursing students to appropriately administer naloxone to reverse OOD and provide immediate recovery care after revival. PURPOSE Patients receiving extracorporeal membrane oxygenation (ECMO) commonly develop acute kidney injury (AKI) and frequently require continuous renal replacement therapy (CRRT). The impact of different CRRT modalities on survival in patients receiving ECMO remains unclear. MATERIALS AND METHODS Using claims data from Taiwan's National Health Insurance Research Database, a total of 1077 patients who received ECMO and either continuous venovenous hemofiltration (CVVH) or continuous venovenous hemodialysis (CVVHD) for AKI were identified. Inverse probability of treatment weighting was applied using propensity scores to balance the baseline covariates of the two groups. The primary outcome was in-hospital morality. RESULTS We identified 1077 patients (mean age 57.9; 71.8% men). Postcardiotomy shock (49.2%) was the most frequently reported indication for ECMO. The CVVH group had a lower risk of in-hospital mortality (68.4% vs. 76.9%; odds ratio 0.65; 95% confidence interval [CI] 0.50-0.85) compared with the CVVHD group. The CVVH group also had a shorter mean ICU stay compared with the CVVHD group (mean difference -4.59 days, 95% CI -9.15 to -0.03 days). CONCLUSION Our results suggest that compared with CVVHD, CVVH may be associated with a lower risk of in-hospital mortality in patients with AKI who receive ECMO. Antibody levels to periodontal pathogens in prediction of cardiovascular disease (CVD) mortality were explored using data from a health survey in Oslo in 2000 (Oslo II-study) with 12 1/2 years follow-up. IgG antibodies to four common periodontal pathogens; Tannerella forsythia (TF), Porphyromonas gingivalis (PG), and Treponema denticola (TD) all termed collectively the "red complex", and Aggregatibacter actinomycetemcomitans(AA) were analysed. The study sample consisted of 1172 men drawn from a cohort of 6,530 men who participated in the Oslo II-study, where they provided information on medical and dental history. Of the study sample, 548 men had reported prior myocardial infarction (MI) at baseline whereas the remaining 624 men were randomly drawn from the ostensibly healthy participants for comparative analyses. Dental anamnestic information included tooth extractions and oral infections. An inverse relation was found for trend by the quartile risk level of TF predicting CVD mortality, p-value for trend = 0.017. Comparison of the first to fourth quartile of TF antibodies resulted in hazard ratio (HR) = 1.82, 95% confidence interval 1.12-2.94, p = 0.015, adjusted for age, education, diabetes, daily smoking, and systolic blood pressure. Specificity comparing decile 1 to deciles 2-10 of TF predicting mortality was 92.3%. We found an increased HR by low levels of antibodies to the bacterium T. forsythia predicting CVD mortality in a 12 ½ years follow-up in persons who had experienced an MI but not among non-MI men. This novel finding constitutes a plausible causal link between oral infections and CVD mortality. Herein we describe for the first time a practical analytical method for determining the enantio-purity of L-α-glycerophosphocholine (L-α-GPC) by chiral derivatization. The use of a suitable chiral boronic acid allowed the formation of a mixture of two diastereomeric boronate esters whose ratio, carefully analyzed by 1HNMR spectroscopy, reflects L-α-GPC enantiomeric excesses. link2 The determination of the enantiopurity of L-α-GPC furnishes convincing correlations with its manufacturing process. BACKGROUND The association of antiseizure medication (ASM) and bone density abnormalities has long been recognized; however, there remains a lack of consensus on efficacy and optimal vitamin D dosing in patients receiving enzyme inducing and non-inducing ASMs. The objective was to explore the relationship between ASMs and vitamin D supplementation requirements in a population of adult patients with epilepsy. METHODS Patients with a diagnosis of epilepsy receiving supplemental vitamin D were included in this retrospective chart review. All instances of 25-hydroxyvitamin D3 (25-OHD) measured among those patients were compared between patients taking an enzyme inducing antiseizure medication (EIASM) to patients receiving ASM regimens only containing non-enzyme inducing antiseizure medications (NIASM). ASM use, prescription and over the counter (OTC) vitamin D use, 25-OHD plasma concentration, presence of chronic kidney disease (CKD), age, gender, and ethnicity were collected. Multiple linear regression was used ower dose OTC requires closer monitoring of vitamin D status in patients with epilepsy, especially those on EIASMs, is warranted. vitamin D agent may not be adequate. OBJECTIVE To determine whether clinical outcomes are improved after repeat surgery for medically refractory epilepsy in children. METHODS This is a single-center retrospective cohort analysis of all patients who received repeat resective surgery for ongoing seizures from 2000-2017. From a total of 251 consecutive individual epilepsy surgical patients for focal resection, 53 patients met study inclusion criteria and had adequate follow-up documented. RESULTS Median age of seizure-onset was 2.0-years-old (IQR 0.3-5.5 years). The median age at first epilepsy surgery was 6.3-years-old (IQR 2.9-9.2 years) and at second epilepsy surgery was 8.4-years-old (IQR 4.7-12.6 years). Overall, 53 % (n = 28) of this series achieved Engel Class I (seizure freedom); with improved seizure control (Engel Class I-II) in 83 % (n = 44) of the cohort. link3 64 % (n = 34) had one reoperation; 26 % (n = 14) had two; and 9% (n = 5) had three. Pathology 58 % (n = 31) had focal cortical dysplasia; 13 % (n = 10) tumor; 9% (n = 5) encephalitis; 6% (n = 3) gliosis; 4% (n = 2) mesial temporal sclerosis; and 2% (n = 1) hemimegalencephaly. Tumor pathology was associated with increased chance (p = 0.01) for seizure freedom (90 % of tumor patients had Engel Class I outcome). MTS had worse outcome with both patients having ongoing seizures (Engel II-IV). There were 6 patients who developed post-operative hemiparesis; one was unplanned but resolved. SIGNIFICANCE Reoperation for pediatric epilepsy surgery can lead to seizure freedom in many cases and improved seizure control in most cases. Reoperation for brain tumor pathology is associated with a high rate of seizure freedom. OBJECTIVE Certain antiepileptic drugs (AEDs) may be more suitable for elderly patients with epilepsy (EWE) relative to others. However, little is known regarding which antiepileptic drugs (AEDs) are being used to treat EWE in the United States and how it has changed over time. METHODS We performed a serial cross-sectional study evaluating noninstitutionalized US adults aged 65 years or older with a diagnosis of epilepsy using data from the Medical Expenditure Panel Survey (MEPS) from 2004 through 2015. Trends in AEDs used among EWE were examined. Using each AED as a dependent variable, we determined the p-value for the trend by performing a linear regression with the time interval as the explanatory variable. RESULTS There was a weighted total of 399,801 EWE. Between the years 2004-2006 and 2013-2015 use of phenytoin, carbamazepine and phenobarbital decreased from 60.7% to 31.1% (p ≤ 0.001), 13.7 % to 5.22 % (p = 0.03) and 12.5 % to 5.91 % (p = 0.04), respectively. Use of levetiracetam concomitantly increased from 6.
