- Abstract
Objective Elevated aldosterone is associated with increased risk of atherosclerosis complications, whereas treatment with mineralocorticoid receptor (MR) antagonists decreases the rate of cardiovascular events. Here we test the hypothesis that aldosterone promotes early atherosclerosis by modulating intercellular adhesion molecule-1 (ICAM-1) expression and investigate the molecular mechanisms by which aldosterone regulates ICAM-1 expression. Methods and results Apolipoprotein-E (ApoE)−/− mice fed an atherogenic diet and treated with aldosterone for 4 weeks showed increased vascular expression of ICAM-1, paralleled by enhanced atherosclerotic plaque size in the aortic root. Moreover, aldosterone treatment resulted in increased plaque lipid and inflammatory cell content, consistent with an unstable plaque phenotype. ApoE/ICAM-1 double knockout (ApoE−/−/ICAM-1−/−) littermates were protected from the aldosterone-induced increase in plaque size, lipid content and macrophage infiltration. Since aldosterone is known to regulate ICAM-1 transcription via MR in human endothelial cells, we explored MR regulation of the ICAM-1 promoter. Luciferase reporter assays performed in HUVECs using deletion constructs of the human ICAM-1 gene promoter showed that a region containing a predicted MR-responsive element (MRE) is required for MR-dependent transcriptional regulation of ICAM-1. Conclusions Pro-atherogenic effects of aldosterone are mediated by increased ICAM-1 expression, through transcriptional regulation by endothelial MR. These data enhance our understanding of the molecular mechanism by which MR activation promotes atherosclerosis complications.

- Abstract
Introduction: Cognitive activity and awareness during cardiac arrest (CA) are reported but ill understood. This first of a kind study examined consciousness and its underlying electrocortical biomarkers during cardiopulmonary resuscitation (CPR)., Methods: In a prospective 25-site in-hospital study, we incorporated a) independent audiovisual testing of awareness, including explicit and implicit learning using a computer and headphones, with b) continuous real-time electroencephalography(EEG) and cerebral oxygenation(rSO
2 ) monitoring into CPR during in-hospital CA (IHCA). Survivors underwent interviews to examine for recall of awareness and cognitive experiences. A complementary cross-sectional community CA study provided added insights regarding survivors' experiences., Results: Of 567 IHCA, 53(9.3%) survived, 28 of these (52.8%) completed interviews, and 11(39.3%) reported CA memories/perceptions suggestive of consciousness. Four categories of experiences emerged: 1) emergence from coma during CPR (CPR-induced consciousness [CPRIC]) 2/28(7.1%), or 2) in the post-resuscitation period 2/28(7.1%), 3) dream-like experiences 3/28(10.7%), 4) transcendent recalled experience of death (RED) 6/28(21.4%). In the cross-sectional arm, 126 community CA survivors' experiences reinforced these categories and identified another: delusions (misattribution of medical events). Low survival limited the ability to examine for implicit learning. Nobody identified the visual image, 1/28(3.5%) identified the auditory stimulus. Despite marked cerebral ischemia (Mean rSO2 = 43%) normal EEG activity (delta, theta and alpha) consistent with consciousness emerged as long as 35-60 minutes into CPR., Conclusions: Consciousness. awareness and cognitive processes may occur during CA. The emergence of normal EEG may reflect a resumption of a network-level of cognitive activity, and a biomarker of consciousness, lucidity and RED (authentic "near-death" experiences)., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023.

- Abstract
Government policies recommend, and all stakeholders benefit, when mental health services meaningfully engage with carers and family. However, health service engagement with carers is inadequate, and often non-existent with children whose parents are service users. There are seven fundamental ways that carers and families want to be integrated with and engaged by health services but current survey instruments do not capture these seven engagement practices. This protocol describes the development of two closely aligned Family and Carer Surveys (FACS) to measure engagement of service users in mental health services. The new measures are based on the seven engagement themes and a conceptual distinction between the carer and family, with particular focus on where the service user is a parent. The instruments will be developed in five stages; (1) item generation (2) Cognitive pretesting of survey (3) preliminary item content quantitative assessment (4) psychometric analysis of a large data collection and (5) selection of items for short form instruments. These steps will operationalise the seven fundamental ways that families and carers want to be engaged with mental health services, thereby providing valid and reliable measures for use in research and benchmarking of carer and family engagement.

- Abstract
Background and Objectives: The impact of the Best Pharmaceuticals for Children Act (BPCA) and the Pediatric Research Equity Act (PREA) on pediatric antibacterial or antifungal drug trials is unknown. Our objective was to identify and characterize trials conducted under the BPCA and/or the PREA., Methods: Pediatric antibacterial and antifungal drug trials with industry or US federal funding registered in clinicaltrials.gov from 2007 to 2017 were identified. Those conducted under BPCA and/or PREA were identified through US Food and Drug Administration and National Institute of Child Health and Human Development databases., Results: Of 17 495 pediatric trials registered on clinicaltrials.gov between October 2007 and September 2017, 122 systemic antibacterial or antifungal drug trials with industry or US federal funding were identified. Of these 122 trials, 98 (80%) involved antibacterials only, 23 (19%) antifungals only, and 1 (1%) both antibacterials and antifungals. These represented <1% (122 of 17 495) of pediatric trials. Neither pediatric antibacterial nor antifungal drug trials commonly enrolled neonates 0 to 30 days old (30% [30 of 99] vs 42% [10 of 24], respectively). Pediatric antibacterial and antifungal trials were commonly industry funded (79% [78 of 99] and 83% [20 of 24], respectively). In total, 65% (79 of 122) of pediatric antibacterial and/or antifungal drug trials were conducted under BPCA and/or PREA. Researchers in trials conducted under BPCA and/or PREA, relative to non-BPCA and/or PREA trials, more often collected pharmacokinetic data (70% [55 of 79] vs 26% [11 of 43])., Conclusions: Although the majority of pediatric antibacterial and/or antifungal drug trials were conducted under BPCA and/or PREA, the overall number was low. Greater effort is needed to stimulate such trials., Competing Interests: POTENTIAL CONFLICT OF INTEREST: Dr Benjamin has received grants and revenue from AstraZeneca, Cempra Pharmaceuticals, Shionogi Inc, The Medicines Company, and Cidara Therapeutics, which are unrelated to the current study. Dr Smith has consulted on antifungal trials for Astellas Pharma Inc; the other authors have indicated they have no potential conflicts of interest to disclose., (Copyright © 2018 by the American Academy of Pediatrics.)

- Abstract
Background: Heart failure (HF) involves myocardial fibrosis and dysregulated angiogenesis., Objective: We explored whether biomarkers of fibrosis and angiogenesis correlate with HF severity., Methods: Biomarkers of fibrosis [procollagen types I and III (PIP and P3NP), carboxyterminal-telopeptide of type I collagen (ICTP), matrix metalloproteases (MMP2 and MMP9), tissue inhibitor of MMP1 (TIMP1)]; and angiogenesis [placental growth factor (PGF), vascular endothelial growth factor (VEGF), soluble Fms-like tyrosine kinase-1 (sFlt1)] were measured in 52 HF patients and 19 controls., Results: P3NP, ICTP, MMP2, TIMP1, PGF, and sFlt1 levels were elevated in HF, while PIP/ICTP, PGF/sFlt1, and VEGF/sFlt1 ratios were reduced. PIP/ICTP, MMP-9/TIMP1, and VEGF/sFlt1 ratios were lowest among patients with severe HF., Conclusions: Severe HF is associated with collagen breakdown and reduced angiogenesis. A multimarker approach may guide therapeutic targeting of fibrosis and angiogenesis in HF.
