Ampakine pretreatment enables a single hypoxic episode to generate phrenic electric motor facilitation without additional advantage of extra episodes.
Liver fibrosis risk is a heritable trait, the outcome of which is the net deposition of extracellular matrix by hepatic stellate cell-derived myofibroblasts. Whereas nucleotide sequence variations have been extensively studied in liver fibrosis, the role of copy number variations (CNV) in which genes exist in abnormal numbers of copies (mostly due to duplication or deletion) has had limited exploration.

The impact of the XPO4 CNV on histological liver damage was examined in a cohort comprised 646 Caucasian patients with biopsy-proven MAFLD and 170 healthy controls. XPO4 expression was modulated and function was examined in human and animal models.

Here we demonstrate in a cohort of 816 subjects, 646 with biopsy-proven metabolic associated liver disease (MAFLD) and 170 controls, that duplication in the exportin 4 (XPO4) CNV is associated with the severity of liver fibrosis. Functionally, this occurs via reduced expression of hepatic XPO4 that maintains sustained activation of SMAD3/SMAD4 and promotes TGFr grant 634413 for the project EPoS.

One prominent application for deep learning-based classifiers is skin cancer classification on dermoscopic images. However, classifier evaluation is often limited to holdout data which can mask common shortcomings such as susceptibility to confounding factors. To increase clinical applicability, it is necessary to thoroughly evaluate such classifiers on out-of-distribution (OOD) data.

The objective of the study was to establish a dermoscopic skin cancer benchmark in which classifier robustness to OOD data can be measured.

Using a proprietary dermoscopic image database and a set of image transformations, we create an OOD robustness benchmark and evaluate the robustness of four different convolutional neural network (CNN) architectures on it.

The benchmark contains three data sets-Skin Archive Munich (SAM), SAM-corrupted (SAM-C) and SAM-perturbed (SAM-P)-and is publicly available for download. To maintain the benchmark's OOD status, ground truth labels are not provided and test results should be sent tovaluation process and thereby enable the development of more robust skin cancer classifiers.
The REGOMA trial showed that regorafenib significantly improved overall survival in patients with recurrent glioblastoma compared with lomustine. Patients treated with regorafenib experienced a higher occurrence of grade 3-4 drug-related adverse events than those receiving the standard treatment. Because this safety profile was expected, it was considered of great importance to assess the patient point of view regarding the disease and treatment impact on different aspects of life and patient well-being. We here report the final results of the health-related quality of life (HRQoL) assessment, a secondary end-point of the study. This trial is registered with ClinicalTrials.gov, NCT02926222.

Patient-reported outcomes were assessed, within a prospective, randomised, multicentre, open-label phase II trial, by the European Organisation for Research and Treatment of Cancercore questionnaireand brain moduleat baseline and every 8-weekly neuroradiological assessment till disease progression. Mixed-effect linear urvival benefit shown in the REGOMA trial support the use of regorafenib as a treatment option for these patients.
Regorafenib did not negatively affect HRQoL in patients with recurrent glioblastoma. These data combined with the survival benefit shown in the REGOMA trial support the use of regorafenib as a treatment option for these patients.The design of clinical trials with outcomes reported in cohorts including nested subgroups is common in novel agents seeking new indications for approval. This structure represents a tension between drug companies that have an incentive to pursue broad biomarker-agnostic approvals and patients whose best interest is to identify the subgroup(s) most likely to benefit from the drug. Programmed death ligand 1 (PD-L1) and checkpoint inhibitors are a prominent example with early trials reporting efficacy of checkpoint inhibitors in cohorts with high levels of PD-L1. Subsequent analyses incrementally report outcomes in broader patient cohorts that include the nested subgroup of high PD-L1 expression which drives the positive outcome in the entire cohort. Comparing aggregate outcomes between groups of patients with known heterogeneous outcomes deters the effective analysis of all available data. FDA-approved Drug Library Exploring the optimal treatment for individual patients with different levels of PD-L1 expression, whether it is checkpoint inhibitors only, checkpoint inhibitors combined with chemotherapy or chemotherapy only, requires a granular approach to trial design and reporting. Such grouping of patients with different biomarker findings is increasingly seen in the setting of adjuvant therapy, as well as in targeted therapies that show efficacy in a single gene mutation which however are studied in the setting of panels of mutations. Here we discuss the difference between nested and adjacent subgroups in oncology.
Little research has been conducted that compares suicide cases with and without schizophrenia. The aim of the present study was to identify demographic, personal, social, relational, and psychological characteristics among suicides identified posthumously with schizophrenia compared to those without.

The DSM-IV was used to independently assess the presence of schizophrenia among suicide cases by two psychiatrists. Data on risk factors was collected through a psychological autopsy method, which included structured interviews of two informants for each suicide case (a family member and a close friend). Interview questions included demographic characteristics, suicide risk factors, the Beck Hopelessness Scale, Dickman's Impulsivity Inventory, the Spielberger State-Trait Anxiety Inventory, the Hamilton Depression Scale and the Duke Social Support Inventory.

The prevalence of schizophrenia was 9.69% among suicide cases in this sample. The schizophrenia suicide group was more likely to be female, older, in poorer physical health, suffer from chronic disease, suffer other psychological disorders, and have a family history of psychological disorders compared to those not diagnosed schizophrenia. Other important risk factors included more frequent past suicide attempts, increased levels of depression and anxiety, lower levels of impulsivity, lower help seeking from friends, and lower social interaction social support.

There is a notable link between schizophrenia and suicide in China. Identification of social, personal, relational, and psychological risk factors could beneficially guide attempts to improve future preventive measures against suicide among those with schizophrenia in China.

The aim of the COVID-19 Psychological Wellbeing Study was to identify trajectories of anxiety, depression and COVID-19-related traumatic stress (CV19TS) symptomology during the first UK national lockdown. We also sought to explore risk and protective factors. The study was a longitudinal, three-wave survey of UK adults conducted online. Analysis used growth mixture modelling and logistic regressions. Data was collected from 1958 adults. A robust 4-class model for anxiety, depression, and CV19TS symptomology distinguished participants in relation to the severity and stability of symptomology. Classes described low and stable and high and stable symptomology, and symptomology that improved or declined across the study period. Several risk and protection factors were identified as predicting membership of classes (e.g., mental health factors, sociodemographic factors and COVID-19 worries). This study reports trajectories describing a differential impact of COVID-19 on the mental health of UK adults. Some adults experienced psychological distress throughout, some were more vulnerable in the early weeks, and for others vulnerability was delayed. These findings emphasise the need for appropriate mental health support interventions to promote improved outcomes in the COVID-19 recovery phase and future pandemics.
Neuregulin1β1 (NRG1β1) is essential for neuronal migration during development and for the ongoing neural plasticity underlying cognitive function. This study investigated the relationship between cognitive impairment and serum NRG1β1 concentration in first-episode drug-naïve (FEDN) patients with schizophrenia.

We measured serum NRG1β1 from 65 FEDN schizophrenia patients and 67 healthy matched controls. Cognitive function was evaluated using the Hopkins Vocabulary Learning Test-Revised (HVLT-R), Verbal Fluency Test (VFT), Trail Making Test (TMT), Digit Span Test (DST), and Stroop Test.

Serum NRG1β1 concentration was significantly lower in the FEDN patient group than the control group (7.25±0.49 vs. 12.52±0.77 ng/mL; F=23.716, P<0.0001, Cohen's d=1.00). Further, serum NRG1β1 concentration in FEDN schizophrenia patients was negatively correlated with TMT-part A score (r=-0.408, P=0.001) and positively correlated with Stroop color subtest score (r=0.246, P=0.048). Multiple regression analysis also revealed weak correlations among FEDN patients between TMT-part A score and both serum NRG1β1 concentration (R
=0.116, F=8.235, P=0.011) and duration of untreated psychosis (R
=0.193, F=5.969, P=0.017).

This preliminary study suggests that serum NRG1β1 levels are reduced in FEDN patients with schizophrenia and that NRG1β1 may be involved in the cognitive function.

Neuromuscular monitoring has become a standard of care for management of anesthesia. While acceleromyography (AMG) is the most common technology used in clinical practice, guidelines suggest that electromyographic (EMG) devices are ideal for quantitative neuromuscular monitoring. The Tetragraph® is an EMG monitor that has recently been marketed.

The aim of this study is to assess the agreement during recovery from neuromuscular blockade of this new monitor with the TOF Watch® SX, and to compare intraobserver variability for the two devices.

Single-center, prospective, observational clinical study.

Operating room.

Twenty-three patients were enrolled and twenty patients were included in the analysis.

A comparison of TOF-ratios measured sequentially from the same hand with the Tetragraph and TOF Watch SX was conducted during spontaneous recovery of neuromuscular function from patients that received rocuronium during surgery.

We used Bland-Altman plots for repeated measures to compare TOF-ratios obtained sequentially by the two devices.
