Intestinal epithelial cells have a rapid turnover, being rapidly renewed by newly differentiated enterocytes, balanced by massive and constant removal of damaged cells by programmed cell death (PCD). The main forms of PCD are apoptosis, pyroptosis, and necroptosis, with apoptosis being a noninflammatory process, whereas the others drive innate immune responses. Although apoptosis is thought to be the principal means of cell death in the healthy intestine, which mechanisms are responsible for PCD during inflammation are not fully understood. To address this question, we used an in vivo model of enteropathy in wild-type mice induced by a single intragastric administration of the p31-43 gliadin peptide, which is known to elicit transient MyD88, NLRP3, and caspase-1-dependent mucosal damage and inflammation in the small intestine. Here, we found increased numbers of TUNEL+ cells in the mucosa as early as 2 h after p31-43 administration. Western blot and immunofluorescence analysis showed the presence of caspase-3-mediated apoptosis in the epithelium and lamina propria. In addition, the presence of mature forms of caspase-1, IL-1β, and gasdermin D showed activation of pyroptosis and inhibition of caspase-1 led to decreased enterocyte death in p31-43-treated mice. There was also up-regulation of RIPK3 in crypt epithelium, suggesting that necroptosis was also occurring. Taken together, these results indicate that the inflammatory response induced by p31-43 can drive multiple PCD pathways in the small intestine.Lay-caregivers are essential to the continuum of care in adult organ transplantation. However, we have a limited understanding of the experiences, exigencies, and outcomes associated with lay-caregiving for organ transplant patients. While much discussion and debate has focused on caregiver requirements in relation to transplant candidate selection, little focus has been given to understanding the needs of caregivers themselves. In response to this, the Organ Transplant Caregiver Initiative was created, and a meeting was held during October 6-7, 2019. Transplant healthcare professionals, researchers, and lay-caregivers discussed the experiences, educational needs, existing research, and research recommendations to improve the experience of lay-caregivers for adult organ transplant patients. In this report, we summarize the Organ Transplant Caregiver Initiative and meeting findings, providing a preliminary action plan to improve education, research, and advocacy for organ transplant caregivers.

Fibrosis is the strongest predictor for long-term clinical outcomes among patients with non-alcoholic fatty liver disease (NAFLD). There is growing interest in employing non-invasive methods for risk stratification based on prognosis. FIB-4, NFS and APRI are models commonly used for detecting fibrosis among NAFLD patients. #link# We aimed to synthesize existing literature on the ability of these models in prognosticating NAFLD-related events.

A sensitive search was conducted in two medical databases to retrieve studies evaluating the prognostic accuracy of FIB-4, NFS and APRI among NAFLD patients. Target events were change in fibrosis, liver-related event and mortality. Two reviewers independently performed reference screening, data extraction and quality assessment (QUAPAS tool).

A total of 13 studies (FIB-412, NFS 11, APRI 10), published between 2013 and 2019, were retrieved. All studies were conducted in a secondary or tertiary care setting, with follow-up ranging from 1 to 20years. All three markers showed consistently good prognostication of liver-related events (AUC from 0.69 to 0.92). For mortality, FIB-4 (AUC of 0.67-0.82) and NFS (AUC of 0.70-0.83) outperformed APRI (AUC of 0.52-0.73) in all studies. All markers had inconsistent performance for predicting change in fibrosis stage.

FIB-4, NFS, and APRI have demonstrated ability to risk stratify patients for liver-related morbidity and mortality, with comparable performance to a liver biopsy, although more head-to-head studies are needed to validate this. More refined models to prognosticate NAFLD-events may further enhance performance and clinical utility of non-invasive markers.

At the end of 2019, a novel coronavirus (COVID-19) was identified in China. The high potential of human-to-human transmission led to subsequent COVID-19 global pandemic. Public health strategies including reduced social contact and lockdown have been adopted in many countries. Nonetheless, social distancing and isolation could also represent risk factors for mental disorders, resulting in loneliness, reduced social support and under-detection of mental health needs. link2 Along with this, social distancing determines a relevant obstacle for direct access to psychiatric care services. The pandemic generates the urgent need for integrating technology into innovative models of mental healthcare.

In this paper, we discuss the potential role of telepsychiatry (TP) and other cutting-edge technologies in the management of mental health assistance. We narratively review the literature to examine the advantages and risks related to the extensive application of these new therapeutic settings, along with the possible limitations and ethical concerns.

Fatostatin may be particularly feasible and appropriate for the support of patients, family members and healthcare providers during this COVID-19 pandemic. The integration of TP with other technological innovations (eg, mobile apps, virtual reality, big data and artificial intelligence (AI)) opens up interesting future perspectives for the improvement of mental health assistance.

Telepsychiatry is a promising and growing way to deliver mental health services but is still underused. The COVID-19 pandemic may serve as an opportunity to introduce and promote, among numerous mental health professionals, the knowledge of the possibilities offered by the digital era.

To develop and internally validate risk prediction models identifying women at risk for cardiovascular severe maternal morbidity (CSMM).

A retrospective cohort study.

An obstetric teaching hospital between 2007 and 2017.

A total of 89681 delivery hospitalisations.

We created and evaluated two models, one predicting CSMM at delivery (delivery model) and the other predicting CSMM postpartum following discharge from delivery hospitalisation (postpartum CSMM). We assessed model discrimination and calibration and used bootstrapping for internal validation.

Cardiovascular severe maternal morbidity comprised the following confirmed conditions pulmonary oedema/acute heart failure, myocardial infarction, aneurysm, cardiac arrest/ventricular fibrillation, heart failure/arrest during surgery or procedure, cerebrovascular disorders, cardiogenic shock, conversion of cardiac rhythm and difficult-to-control severe hypertension.

The delivery model contained 11 variables and 3 interaction terms. The strongest predictors were gestational hypertension, chronic hypertension, multiple gestation, cardiac lesions or valvular heart disease, maternal age ≥40years and history of poor pregnancy outcome. The postpartum model comprised eight variables. The strongest predictors were severe pre-eclampsia, non-Hispanic Black race/ethnicity, chronic hypertension, gestational hypertension, non-severe pre-eclampsia and maternal age ≥40years at delivery. The delivery and postpartum models had an area under the receiver operating characteristic curve of 0.87 (95% CI 0.85-0.89) and 0.85 (95% CI 0.80-0.90), respectively. Both models were adequately calibrated and performed well on internal validation.

These tools may help providers to identify women at highest risk of CSMM and enable future prevention measures.

Risk assessment tools for cardiovascular severe maternal morbidity were developed and internally validated.

Ocular manifestations in dermatological diseases are common and have diagnostic value. At present, there are a limited number of comprehensive reviews emphasizing the ocular manifestations of dermatological diseases. More than 40 published articles about ocular findings in dermatology were reviewed. The search included Pubmed, Google Scholar, and Cochrane databases from 2014 to 2019. This review was divided into three parts including I. infectious and inflammatory disorders; II. genodermatoses; III. connective tissue, autoimmune, neoplasms, and drug-related disorders. We excluded metabolic, endocrine, and nutrition-related dermatological diseases. In this part, we summarized the most common and important ocular findings in dermatology-related genetic disorders with appropriate referral recommendations to ophthalmology.Extracellular vesicles (EVs) are important elements of intercellular communication. A plethora of different, occasionally even opposite, physiologic and pathologic effects have been attributed to these vesicles in the last decade. A direct comparison of individual observations is however hampered by the significant differences in the way of elicitation, collection, handling, and storage of the investigated vesicles. In the current work, we carried out a careful comparative study on 3, previously characterized types of EVs produced by neutrophilic granulocytes. We investigated in parallel the modulation of multiple blood-related cells and functions by medium-sized vesicles. We show that EVs released from resting neutrophils exert anti-inflammatory action by reducing production of reactive oxygen species (ROS) and cytokine release from neutrophils. In contrast, vesicles generated upon encounter of neutrophils with opsonized particles rather promote proinflammatory processes as they increase production of ROS and cytokine secretion from neutrophils and activate endothelial cells. link3 EVs released from apoptosing cells were mainly active in promoting coagulation. We thus propose that EVs are "custom made," acquiring selective capacities depending on environmental factors prevailing at the time of their biogenesis.

Western corn rootworm (WCR) pyrethroid resistance has been confirmed in the western US Corn Belt. Toxicological and biochemical studies indicated that multiple mechanisms of resistance might be involved in the resistance trait, such as enhanced metabolism and/or kdr target-site mutation(s) in the voltage-gated sodium channels. To characterize the mechanisms of WCR pyrethroid resistance at the molecular level, pairwise comparisons were made between RNA-Seq data collected from pyrethroid-resistant and -susceptible WCR populations. Gene expression levels and sodium channel sequences were evaluated.

Seven transcripts exhibited significantly different expression (q ≤ 0.05) when comparing field-collected pyrethroid-resistant (R-Field) and -susceptible (S-Field) WCR populations. Three of the differentially expressed transcripts were P450s overexpressed in R-Field (9.2-26.2-fold). A higher number (99) of differentially expressed transcripts was found when comparing laboratory-derived pyrethroid-resistant (R-Lab) and -susceptible (S-Lab) WCR populations.
