Lysophosphatidic acid receptor 1 (LPA1) is a receptor of lysophosphatidic acid (LPA). The present study investigated Lpar1 mRNA expression in the mouse pituitary gland by RT-PCR, in situ hybridization, and immunohistochemistry. Lpar1 mRNA was abundantly expressed in the pituitary gland. learn more In situ hybridization and immunohistochemistry revealed over 90 % of a common glycoprotein α-subunit, luteinizing hormone β-subunit, and thyroid-stimulating hormone β-subunit immunoreactive cells co-expressed Lpar1 mRNA in the anterior pituitary gland, but few growth hormone, adrenocorticotropic hormone, and prolactin cells co-expressed Lpar1. Furthermore, Lpar1 mRNA levels in the pituitary gland were increased after ovariectomy and decreased after E2 administration. These results demonstrate that LPA1-mediated signaling may play physiological roles in gonadotropes and thyrotropes in the mouse pituitary gland.Historical epidemiological perspectives from past pandemics and recent neurobiological evidence link infections and psychoses, leading to concerns that COVID-19 will present a significant risk for the development of psychosis. But are these concerns justified, or mere sensationalism? In this article we review the historical associations between viral infection and the immune system more broadly in the development of psychosis, before critically evaluating the current evidence pertaining to SARS-CoV-2 and risk of psychosis as an acute or post-infectious manifestation of COVID-19. We review the 42 cases of psychosis reported in infected patients to date, and discuss the potential implications of in utero infection on subsequent neurodevelopment and psychiatric risk. Finally, in the context of the wider neurological and psychiatric manifestations of COVID-19 and our current understanding of the aetiology of psychotic disorders, we evaluate possible neurobiological and psychosocial mechanisms as well as the numerous challenges in ascribing a causal pathogenic role to the infection.
Current guidelines do not recommend periodically repeating echocardiograms in the follow-up of stable heart failure patients with reduced ejection fraction (HFrEF). The objective of the study was to verify the additional prognostic information provided by a comprehensive re-assessment of their cardiac function and hemodynamic profile at Doppler echocardiography in HFrEF patients.

Retrospective analysis of 769 stable HFrEF outpatients who underwent two complete echocardiograms, at baseline and at re-assessment. Main candidate predictors of prognosis were left ventricular (LV) filling pattern, pulmonary artery systolic pressure (PASP) and right ventricular function (TAPSE). Age, LV ejection fraction, mitral regurgitation severity, NYHA class, brain natriuretic peptide plasma levels at baseline, and their changes at 12months, were used as covariates. Median follow-up was 30months. All-cause death was the study end-point.

At baseline, restrictive filling pattern and low TAPSE were significant predictors of poor prognosis. At re-evaluation, persistently restrictive/worsened filling pattern, persistently-low/worsened TAPSE and worsened PASP, were associated with poorer survival. A significant interaction between changes in TAPSE, PASP and LV filling pattern was observed in the restrictive pattern subgroup, survival was poorer in worsened/persistently low TAPSE (p<0.01); in non-restrictive pattern subgroup, survival was poorer in worsened/persistently elevated PASP (p=0.01). The re-assessment model improved the C-index from 0.69 to 0.74 (P<0.01) compared to baseline model.

Doppler echocardiographic re-assessment of LV filling pattern, PASP and TAPSE allows a better prognostic stratification of HFrEF outpatients than baseline evaluation and is additional to changes in BNP and NYHA class.

This perspective, observational study evaluated safety and efficacy of the GORE® Cardioform ASD Occluder (WL Gore & Associates, Flagstaff, AZ), compliant and potentially innovative prosthesis recently approved for closure of ostium secundum atrial septal defects (ASD).

Between January and June 2020, 43 unselected patients with -significant ASD were submitted to trans-catheter closure with GORE® Cardioform ASD Occluder at two high-volume Italian Pediatric Cardiology centers. Primary endpoints were procedural success and safety. Secondary endpoints were closure rate and clinical safety at 1-month follow-up.

Patients' age and weight were 8.2±3.9years (range 3-21, median 9.9) and 29.6±15.3kg (range 16-57, median 33.3), respectively. ASD diameter was 16.6±4.5mm (median 10), resulting in QP/QS of 1.7±0.7 (median 1.6). Seventeen pts. (39.5%) were considered "surgical" candidates due to challenging septum morphology, ASD rim deficiency or ASD diameter/patient weight ratio≥1.2. Device placement was successfully achieved in all but one patient (97.7%), in whom it embolized early after deployment, resulting in rescue surgical repair. No cross-over with different devices was recorded. Median procedure and fluoroscopy times were 40 and 6.8min, respectively. Major adverse events were recorded in 7.0% (3 pts). Complete closure rate was 78.5% at discharge, rising to 92.9% (39/42 pts) at 1month evaluation, without cardiac or extra-cardiac adverse events. "Challenging" procedures were more time-consuming but as effective and safe as the "simple" ones.

The GORE® Cardioform ASD Occluder device was highly effective and versatile in closure of ASDs with different anatomy and size, even in challenging settings.

The prevalence of atrial fibrillation (AF) increases with age. The prescription of anticoagulation in very elderly patients is controversial and sometimes underused. Our objective is to report the incidence and predictors of major bleeding in anticoagulated nonagenarian patients with non valvular atrial fibrillation (NVAF).

We analyzed a large multicentre registry of anticoagulated nonagenarian patients diagnosed with NVAF from three health areas of Spain, between 2013 and 2017. Predictors of major bleeding were studied with a competing risk analysis and the impact of major bleeding with a time-dependent mortality analysis.

The incidence rate of major bleeding was 5 per100 person-year (95% Confidence Interval [CI] 4.59-6.35), similar in the group of patients with vitamin K antagonists (VKAs) and direct oral anticoagulants (DOAC). In the VKAs group we found as predictors of major bleeding previous admission for bleeding (sub-distribution hazard ratio [sHR] 3.25, 95% CI 1.48-7.13), creatinine (sHR 1.38, 95% CI 1.
