hat the fine morphological aspect of neurons and dendritic spines are normal in epileptogenic neocortex, with the exception of type II dysplastic lesions. The findings suggest that the mechanisms leading to this severe form of cortical malformation interfere with the normal dendritic arborization and synaptic network organization. The data argue against the concept that long-lasting epilepsy and seizure recurrence per se unavoidably produce a dendritic pathology.Substantial investments are being made to scale-up access to mental healthcare in low- and middle-income countries, but less attention has been paid to quality and performance of nascent public-sector mental healthcare systems. This study tested the initial effectiveness of an implementation strategy to optimize routine outpatient mental healthcare cascade performance in Mozambique [the Systems Analysis and Improvement Approach for Mental Health (SAIA-MH)]. This study employed a pre-post design from September 2018 to August 2019 across four Ministry of Health clinics among 810 patients and 3234 outpatient mental health visits. Effectiveness outcomes evaluated progression through the care cascade, including (1) initial diagnosis and medication selection; (2) enrolling in follow-up care; (3) returning after initial consultation within 60 days; (4) returning for follow-up visits on time; (5) returning for follow-up visits adherent to medication and (6) achieving function improvement. Clustered generalized linearce-based implementation strategies to optimize the performance of mental healthcare cascades in low- and middle-income countries.

This study was undertaken to evaluate the acute and midterm results of endovascular treatment with bare metal stents (BMS) for Leriche syndrome patients.

Patients with Leriche syndrome treated with BMS from August 2008 to May 2017 were included in the study and followed up. The primary endpoints were primary restenosis-free survival rates at 1, 2 and 3 years. The secondary endpoints were secondary restenosis-free and freedom from target lesion revascularization survival rates at 1, 2 and 3 years; technical success rate; complication rate; procedure-related mortality rate; and clinical status improvement at follow-up.

Twenty patients were included and the follow-up duration was 34.7 ± 18.7 months (0-86 months). The 1-, 2- and 3-year primary restenosis-free survival rates were 94.4%, 88.1% and 73.5% and the secondary patency rates were 94.4%, 94.4% and 86.6%, respectively. The freedom from target lesion revascularization survival rates of patients at 1, 2 and 3 years were 94.4%, 88.1% and 79.3%, respectively. The aortoiliac lesions were successfully treated with BMS bilaterally in 17 patients (85.0%) and unilaterally in another 3 patients (15.0%). The complication rate was 10.0% and the procedure-related mortality rate was 0%. Mean ankle-brachial index increased significantly from 0.43 ± 0.20 before the procedure to 0.95 ± 0.21 after the procedure (P < 0.001), and to 1.00 ± 0.19 at the end of the follow-up (P < 0.001). Improvement in symptoms occurred in most patients soon after the endovascular procedure (95.0%) and at follow-up (88.2%).

Endovascular treatment with BMS is effective and safe for patients with Leriche syndrome according to 3-year follow-up results.

As of 1 November 2020, there have been >230 000 deaths and 9 million confirmed and probable cases attributable to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in the United States. However, this overwhelming toll has not been distributed equally, with geographic, race/ethnic, age, and socioeconomic disparities in exposure and mortality defining features of the US coronavirus disease 2019 (COVID-19) epidemic.

We used individual-level COVID-19 incidence and mortality data from the state of Michigan to estimate age-specific incidence and mortality rates by race/ethnic group. Data were analyzed using hierarchical Bayesian regression models, and model results were validated using posterior predictive checks.

In crude and age-standardized analyses we found rates of incidence and mortality more than twice as high than for Whites for all groups except Native Americans. Blacks experienced the greatest burden of confirmed and probable COVID-19 (age-standardized incidence, 1626/100 000 population) and mortality (age-standardized mortality rate, 244/100 000). These rates reflect large disparities, as Blacks experienced age-standardized incidence and mortality rates 5.5 (95% posterior credible interval [CrI], 5.4-5.6) and 6.7 (95% CrI, 6.4-7.1) times higher than Whites, respectively. We found that the bulk of the disparity in mortality between Blacks and Whites is driven by dramatically higher rates of COVID-19 infection across all age groups, particularly among older adults, rather than age-specific variation in case-fatality rates.

This work suggests that well-documented racial disparities in COVID-19 mortality in hard-hit settings, such as Michigan, are driven primarily by variation in household, community, and workplace exposure rather than case-fatality rates.

Genome architecture had been notoriously difficult to elucidate, but the advent of the suite of chromatin conformation capture assays, notably Hi-C, has transformed understanding of chromatin structure and provided downstream biological insights. Although many findings have flowed from direct analysis of the pairwise proximity data produced by these assays, there is added value in generating corresponding 3D reconstructions deriving from superposing genomic features on the reconstruction. Accordingly, many methods for inferring 3D architecture from proximity data have been advanced. However, none of these approaches exploit the fact that single chromosome solutions constitute a one-dimensional (1D) curve in 3D. Rather, this aspect has either been addressed by imposition of constraints, which is both computationally burdensome and cell type specific, or ignored with contiguity imposed after the fact. https://www.selleckchem.com/ Here, we target finding a 1D curve by extending principal curve methodology to the metric scaling problem. We illustrate how this approach yields a sequence of candidate solutions, indexed by an underlying smoothness or degrees-of-freedom parameter, and propose methods for selection from this sequence. We apply the methodology to Hi-C data obtained on IMR90 cells and so are positioned to evaluate reconstruction accuracy by referencing orthogonal imaging data. The results indicate the utility and reproducibility of our principal curve approach in the face of underlying structural variation.Two chromatographic methods were validated for the determination of the widely prescribed analgesic and antipyretic drug combination of paracetamol (PC) (recently integrated into the supportive treatment of COVID-19), propyphenazone (PZ) and caffeine (CF) in the presence of two PC impurities, namely 4-aminophenol and 4-nitrophenol. A "dual-mode" gradient high-performance liquid chromatography method was developed, where the separation was achieved via "dual-mode" gradient by changing both the ternary mobile phase composition (acetonitrile methanol water) and the flow rate. This enables a good resolution within a relatively shorter analysis time. The analysis was realized using Zorbax Eclipse XDB column C18, 5 μm (250 × 4.6 mm) and the UV detector was set at 220 nm. The other method is a thin-layer chromatography densitometry method, where the separation was achieved using a mobile phase composed of chloroform toluene ethyl acetate methanol acetic acid (6 6 1 2 0.1, by volume). Densitometric detection was performed at 220 nm on silica gel 60 F254 plates. The developed methods were fully validated as per the ICH guidelines and proved to be accurate, robust, specific and suitable for application as purity indicating methods for routine analysis of PC in pure form or in pharmaceuticals with PZ and CF in quality control laboratories.

Acute respiratory distress syndrome carries a 40% mortality rate. Prone positioning remains underused owing to clinicians' low degree of confidence, concern about the risk of adverse outcomes, and lack of staff competency training.

A prone positioning protocol and educational program were needed in an intensive care unit to achieve compliance with best practices for treating acute respiratory distress syndrome patients.

An initial survey was conducted to measure staff confidence and competency in prone positioning. A literature review was performed, and a plan-do-study-act approach was used to develop a protocol through in situ simulation involving mock patients. A training video and a simulation scenario using a high-fidelity manikin were developed to facilitate staff education. Staff were surveyed again after training.

During the simulation scenario, interdisciplinary clinicians learned to apply the protocol and resupinate the patient during a simulated emergency. The training video was later used for "just in time" education minutes before actual prone positioning events.

A total of 25 critical care nurses, 11 respiratory therapists, and 10 physicians completed the initial survey and simulation training. The survey showed that staff lacked confidence and competency in prone positioning. Staff demonstrated competence during the simulation sessions, and posttraining surveys indicated increased confidence. After the educational program, prone positioning was successfully used for 6 critically ill acute respiratory distress syndrome patients.

In situ simulation and interdisciplinary collaboration increase standardization of high-risk, underused procedures, improving staff confidence and competence as well as patient safety.

F13A1/FXIII-A transglutaminase has been linked to adipogenesis in cells and to obesity in humans and mice, however, its role and associated molecular pathways in human acquired excess weight have not been explored.

We examined F13A1 expression and association to human weight gain in weight-discordant monozygotic twins (Heavy-Lean difference (ΔWeight, 16.8 kg ± 7.16 for n = 12). The twin pairs were examined for body composition (by dual-energy X-ray absorptiometry), abdominal body fat distribution (by magnetic resonance imaging), liver fat content (by magnetic resonance spectroscopy), circulating adipocytokines, leptin and adiponectin, as well as serum lipids. Affymetrix full transcriptome mRNA analysis was performed from adipose tissue and adipocyte-enriched fractions from subcutaneous abdominal adipose tissue biopsies. F13A1 differential expression between the heavy and lean co-twins was examined and its correlation transcriptome changes between co-twins were performed.

F13A1 mRNA showed significant increase in adipose tissue (p < 0.
