Is Aberrant Reno-Renal Reflex Control of Blood Pressure a Contributor to Chronic Intermittent Hypoxia-Induced Hypertension?
This study demonstrated unaltered vascular conductance in response to lumbar sympathetic stimulation in CIH-exposed rats. Aortic compliance was increased and estimated blood volume was unchanged in CIH-exposed rats. Increased blood pressure was related to an increase in cardiac output, which was confirmed by echocardiography (Lucking et al., 2014). It is suggested therefore that hypertension in the CIH model can be evoked by over-excitation of the cardiac arm of sympathetic nervous system (SNS), even before mechanisms of enhanced peripheral vasoconstriction and endothelial dysfunction are initiated (Naghshin et al., 2009)....

207 Acute Incidence of Disease at Elevated Levels of Fine Particulate Matter (PM2.5) in Dublin, Ireland
ConclusionControls need to be brought in to ensure that PM2.5 does not exceed a 50μg/m3 level due to the increase in disease incidence associated with same. The urban burning of solid fuels should be severely restricted.

Associations between Ambient Fine Particulate Oxidative Potential and Cardiorespiratory Emergency Department Visits
Conclusions: Lag 0–2 OPDTT was associated with ED visits for multiple cardiorespiratory outcomes, providing support for the utility of OPDTT as a measure of fine particle toxicity. https://doi.org/10.1289/EHP1545 Received: 23 December 2016 Revised: 4 August 2017 Accepted: 12 August 2017 Published: 26 October 2017 Please address correspondence to J.Y.

Trans-catheter paravalvular leak closure: a single-centre experience
ConclusionsPatients with PVL represent a high-risk patient cohort. Percutaneous PVL offers a safe alternative to surgical PVL repair and appears particularly effective in those patients who present primarily with HF.

Atrial Transcriptional Profiles of Molecular Targets Mediating Electrophysiological Function in Aging and Pgc-1 β Deficient Murine Hearts
Conclusion: These findings limit the possible roles of gene transcriptional changes in previously reported age-dependent pro-arrhythmic electrophysiologial changes observed in Pgc-1β-/- atria to an altered Ca2+-ATPase (Atp2a2) expression. This directly parallels previously reported arrhythmic mechanism associated with p21-activated kinase type 1 deficiency. This could add to contributions from the direct physiological outcomes of mitochondrial dysfunction, whether through reactive oxygen species (ROS) production or altered Ca2+ homeostasis. Introduction Atrial arrhythmias constitute a major public health pro...

New Analyses Suggest Favorable Results for STELARA ® (ustekinumab) When Used as a First-Line Therapy for Bio-Naïve Patients with Moderately to Severely Active Crohn’s Disease and Ulcerative Colitis
SPRING HOUSE, PENNSYLVANIA, October 25, 2021 – The Janssen Pharmaceutical Companies of Johnson & Johnson today announced data from two new analyses of STELARA® (ustekinumab) for the treatment of adults with moderately to severely active Crohn’s disease (CD) and ulcerative colitis (UC).1,2 In a modelled analysisa focused on treatment sequencing using data from randomized controlled trials, network meta-analysis and literature, results showed patient time spent in clinical remission or response was highest when STELARA was used as a first-line advanced therapy for bio-naïve patients with moderately to severely acti...

Predicted cardiac and second cancer risks for patients undergoing VMAT for mediastinal Hodgkin lymphoma
ConclusionFor patients with mediastinal lymphoma excess mortality risks from CVD and second cancers remain clinically significant despite contemporary chemotherapy and photon-RT. Efforts to reduce the toxicity of combined modality treatment, for example, using DIBH, reduced margins and advanced RT, e.g. proton beam therapy, should be continued to further reduce potentially fatal treatment effects.
