BACKGROUND The spectrum of injury severity for abusive head trauma (AHT) severity is broad, but outcomes are unequivocally worse than accidental trauma. There are few publications that analyze different outcomes of AHT. OBJECTIVE To determine variables associated with different outcomes of AHT. METHODS Patients were identified using our AHT database. Three different, but not mutually exclusive, outcomes of AHT were modeled (1) death or hemispheric stroke (diffuse loss of grey-white differentiation); (2) stroke(s) of any size; and (3) need for a neurosurgical operation. Demographic and clinical variables were collected and correlations to the 3 outcomes of interest were identified using bivariate and multivariable analysis. RESULTS From January 2009 to December 2017, 305 children were identified through a prospectively maintained AHT database. These children were typically male (60%), African American (54%), and had public or no insurance (90%). A total of 29 children (9.5%) died or suffered a massive hemispheric stroke, 57 (18.7%) required a neurosurgical operation, and 91 (29.8%) sustained 1 or more stroke. Death or hemispheric stroke was statistically associated with the pupillary exam (odds ratio [OR] = 45.7) and admission international normalized ratio (INR) (OR = 17.3); stroke was associated with the pupillary exam (OR = 13.2), seizures (OR = 14.8), admission hematocrit (OR = 0.92), and INR (9.4), and need for surgery was associated with seizures (OR = 8.6). CONCLUSION We have identified several demographic and clinical variables that correlate with 3 clinically applicable outcomes of abusive head injury.

Neuromodulation techniques, including percutaneous trigeminal ganglion (TG) stimulation, are reversible and have emerged as alternative treatment options for intractable facial pain. OBJECTIVE To report the complication rates and analgesic effects associated with TG stimulation and identify potential predictors for these outcomes. METHODS A retrospective chart review of 59 patients with refractory facial pain who underwent TG stimulation was conducted. Outcomes following trial period and permanent stimulation were analyzed. Patients with >50% pain relief during trial stimulation received permanent implantation of the stimulation system. RESULTS Successful trial stimulation was endorsed by 71.2% of patients. During the trial period, 1 TG lead erosion was identified. History of trauma (facial/head trauma and oral surgery) was the only predictor of a failed trial compared to pain of idiopathic etiology (odds ratio 0.15; 95% CI 0.03-0.66). Following permanent implantation, approximately 29.6% and 26.5% of patients were diagnosed with lead erosion and infection of the hardware, respectively. TG lead migrations occurred in 11.7% of the patients. The numeric rating scale score showed a statistically significant reduction of 2.49 (95% CI 1.37-3.61; P = .0001) at an average of 10.8 mo following permanent implantation. CONCLUSION TG stimulation is a feasible neuromodulatory approach for the treatment of intractable facial pain. Ispinesib in vivo Facial/head trauma and oral surgery may predict a nonsuccessful trial stimulation. Future development of specifically designed electrodes for stimulation of the TG, and solutions to reduce lead contamination are needed to mitigate the relatively high complication rate.

In a previous study, it was also found to have a moderately high per generation mutation rate of 2x10-8, likely contributing to its high polymorphism. However, this rate has been measured only in an experiment on Petri dishes, and it is unclear how it translates to natural populations. Here, we used an experimental design that measures the rate of accumulation of de novo mutations in a linearly growing mycelium. We show that Sch. Commune accumulates mutations at a rate of 1.24x10-7 substitutions per nucleotide per meter of growth, or about 2.04x10-11 per nucleotide per cell division. In contrast to what has been observed in a number of species with extensive vegetative growth, this rate does not decline in the course of propagation of a mycelium. As a result, even a moderate per cell division mutation rate in Sch. Commune can translate into a very high per generation mutation rate when the number of cell divisions between consecutive eiosis is large. © The Author(s) 2020.

Although mechano-electrical coupling in TOF is well-known, its time effect on the inducibility of arrhythmia remains ill-defined. The goal of this study was to investigate the mechano-electrical properties at different times in animals with chronic PR. METHODS PR was induced by a transannular patch with limited RV scarring in infant pigs. Haemodynamic assessment included biventricular pressure-volume loops after 3 (n = 8) and 6 months (n = 7) compared to controls (n = 5). The electrophysiological study included endocardial monophasic action potential registration, intraventricular conduction velocity and induction of ventricular arrhythmia by burst pacing. RESULTS Progressive RV dilation was achieved at 6 months (RV end-diastolic volume 143 ± 13 ml/m2-RV end-systolic volume 96 ± 7 ml/m2; P  less then  0.001), inythmia after TOF repair and opens a window for renewed stratification of contemporary risk factors of ventricular arrhythmias in patients operated on with currently used pulmonary valve- and RV-related techniques. © The Author(s) 2020.

We investigated the effect of CPB parameters such as pump flow, haemoglobin concentration and oxygen delivery on clinical outcome and renal function in a propensity matched comparison between MICS and median sternotomy (MS) for atrioventricular valve surgery. METHODS A total of 356 patients undergoing MICS or MS for atrioventricular valve surgery between 2006 and 2017 were analysed retrospectively. Propensity score analysis matched 90 patients in the MS group with 143 in the MICS group. Logistic regression analysis was performed to investigate independent predictors of cardiac surgery-associated acute kidney injury in patients having MICS. RESULTS In MICS, CPB (142.9 ± 39.4 vs 101.0 ± 38.3 min; P  less then  0.001) and aortic cross-clamp duration (89.9 ± 30.6 vs 63.5 ± 23.0 min; P  less then  0.001) were significantly prolonged although no differences in clinical outcomes were det20.

Consistently, studies in a variety of wild populations show virtually no narrow-sense heritability (h2) for traits important to fitness. However, counterexamples are occasionally reported, calling for a deeper understanding on the evolution of additive variance. In this study we propose adaptive divergence followed by population admixture as a source of the additive genetic variance of evolutionarily important traits. We experimentally tested the hypothesis by examining a panel of ∼1,000 yeast segregants produced by a hybrid of two yeast strains that experienced adaptive divergence. We measured over 400 yeast cell morphological traits and found a strong positive correlation between h2 and evolutionary importance. Because adaptive divergence followed by population admixture could happen constantly, particularly in species with wide geographic distribution and strong migratory capacity (e.g., humans), the finding reconciles the observation of abundant additive variances in evolutionarily important traits with Fisher's fundamental theorem of natural selection. Importantly, the revealed role of positive selection in promoting rather than depleting additive variance suggests a simple explanation for why additive genetic variance can be dominant in a population despite the ubiquitous between-gene epistasis observed in functional assays. © The Author(s) 2020.

The evolution of duplicated genes may be influenced by epigenetic processes such as DNA methylation, which affects gene function in some taxa. However, the manner in which DNA methylation affects duplicated genes is not well understood. We studied duplicated genes of the honeybee Apis mellifera, an insect with a highly sophisticated social structure, to investigate whether DNA methylation was associated with gene duplication and genic evolution. We found that levels of gene body methylation were significantly lower in duplicate genes than in single copy genes, implicating a possible role of DNA methylation in post-duplication gene maintenance. Additionally, we discovered associations of gene body methylation with the location, length, and time since divergence of paralogous genes. We also found that divergence in DNA methylation was associated with divergence in gene expression in paralogs, although the relationship was not completely consistent with a direct link between DNA methylation and gene expression. Overall, our results provide further insight into genic methylation and how its association with duplicate genes might facilitate evolutionary processes and adaptation. © The Author(s) 2020.

Thus, enhancing prenatal neurogenesis in DS could prevent or reduce some of the neuromorphological and cognitive defects found in postnatal stages. OBJECTIVES As fatty acids play a fundamental role in morphogenesis and brain development during fetal stages, in this study, we aimed to enhance neurogenesis and the cognitive abilities of the Ts65Dn (TS) mouse model of DS by administering oleic or linolenic acid. METHODS In total, 85 pregnant TS females were subcutaneously treated from Embryonic Day (ED) 10 until Postnatal Day (PD) 2 with oleic acid (400 mg/kg), linolenic acid (500 mg/kg), or vehicle. All analyses were performed on their TS and Control (CO) male and female progeny. At PD2, we evaluated the short-term effects of the treatments on neurogenesis, cellularity, and brain weight, in 40 TS and CO pups. A total of 69 TS and CO mice were used to test the long-term effects of the prenatal treatments on cognition from PD30 to PD45, and on neurogenesis, cellularity, and synaptic markers, at PD45.
