Aim: To assess the safety, tolerability and pharmacodynamics (PD) of the ketohexokinase inhibitor PF-06835919 in participants with non-alcoholic fatty liver disease (NAFLD) and type 2 diabetes (T2D).
Materials And Methods: This double-blind, placebo-controlled, parallel-group study enrolled adults with NAFLD (≥ 8% whole liver fat [WLF] using MRI proton density fat fraction [MRI-PDFF]) and T2D on stable doses of metformin (≥ 500 mg/day). Participants received once-daily placebo, PF-06835919 150 or 300 mg for 16 weeks.
Objectives: To describe the risk of venous thromboembolism (VTE), and risk factors for VTE, in people with immune-mediated inflammatory diseases (IMID) (ulcerative colitis, Crohn's disease (CD), rheumatoid arthritis (RA) and psoriatic arthritis (PsA)), compared with a matched control population.
Methods: A total of 53 378 people with an IMID were identified over 1999-2019 in the UK Royal College of General Practitioners (RCGP) Research and Surveillance Centre (RSC) primary care database and were matched to 213 512 people without an IMID. The association between the presence of any IMID, and each IMID separately, and risk of VTE was estimated using unadjusted and multivariable-adjusted Cox proportional hazards models.
Objective: To assess the burden of cardiovascular disease (CVD) at and prior to diagnosis in people with early rheumatoid arthritis (RA) and subsequent CVD in these patients.
Methods: A retrospective case-control study using a large English primary care database. People with RA (n=6591) diagnosed between 2004 and 2016 (inclusive) were identified using a validated algorithm, matched 1:1 by age and gender to those without RA (n=6591) and followed for a median of 5.
We investigated the biomechanical relationship between intraluminal pressure within small mesenteric resistance arteries, oxidant activation of PKG, Ca sparks, and BK channel vasoregulation. Mesenteric resistance arteries from wild type (WT) and genetically modified mice with PKG resistance to oxidative activation were studied using wire and pressure myography. Ca sparks and Ca transients within vascular smooth muscle cells of intact arteries were characterized using high-speed confocal microscopy of intact arteries.

The association between lung disease and mortality in RA is not well studied; we also explored this relationship.
Methods: From a contemporary UK-based population (n = 1, 475 762) we identified a cohort with incident RA (n = 6591).
Objectives: To describe the prevalence of haematological abnormalities in individuals with RA at the point of diagnosis in primary care and the associations between haematological abnormalities, vaccinations and subsequent risk of common infections.
Methods: We studied 6591 individuals with newly diagnosed RA between 2004 and 2016 inclusive using the UK Royal College of General Practitioners Research and Surveillance Centre primary care database. The prevalence of haematological abnormalities at diagnosis (anaemia, neutropenia and lymphopenia) was established.
Background: Small artery pathophysiology is frequently invoked as a cause of obesity-related diastolic heart failure. However, evidence to support this hypothesis is scant, particularly in humans.
Methods And Results: To address this, we studied human small artery structure and function in obesity and looked for correlations between vascular parameters and diastolic function.
Activation of Ca-sensitive, large-conductance potassium (BK) channels in vascular smooth muscle cells (VSMCs) by local, ryanodine receptor-mediated Ca signals (Ca sparks) acts as a brake on pressure-induced (myogenic) vasoconstriction-a fundamental mechanism that regulates blood flow in small resistance arteries. We report that physiological intraluminal pressure within resistance arteries activated cGMP-dependent protein kinase (PKG) in VSMCs through oxidant-induced formation of an intermolecular disulfide bond between cysteine residues. Oxidant-activated PKG was required to trigger Ca sparks, BK channel activity, and vasodilation in response to pressure.

Statins are the mainstay of treatment but do not address all aspects of CVD risk. Other lipid-lowering therapies are available but are less effective than statins.

Despite a lower point prevalence of AF in Asian communities and Asian countries than in other populations, individuals of Asian ethnicity are at a disproportionately high risk of stroke and have greater consequent mortality. Warfarin and other vitamin K antagonists are conventionally used for anticoagulation, and demonstrably reduce the risk of stroke and all-cause mortality in patients with AF.

Introduction: The prevalence of diabetic nephropathy is increasing as a consequence of the global epidemic of diabetes, and the complications of diabetic nephropathy are unsurprisingly legion. Blockade of the renin-angiotensin-aldosterone system (RAAS) has formed the mainstay of management, but despite this, most individuals will suffer premature cardiovascular events, and many will progress to end-stage renal disease. Given the heterogeneity of pathologies, it is perhaps naïve to hope that blocking a single neurohormonal pathway will protect against the myriad of pathogenetic mechanisms that conspire to cause the injuries seen with diabetes.

Early data suggested that they had a positive impact on the cardiovascular system: treatment appeared to result in improvements in cardiac performance, blood pressure and lipid levels. However, recent clinical findings bring this into question.

Diabetes is a major and growing public health challenge which threatens to overwhelm medical services in the future. Type 2 diabetes confers significant morbidity and mortality, most notably with target organ damage to the eyes, kidneys, nerves and heart. The magnitude of cardiovascular risk associated with diabetes is best illustrated by its position as a coronary heart disease risk equivalent.

View Article and Find Full Text PDFPrevention of target organ damage represents the El Dorado for clinicians who treat hypertension. Although many of the cardiovascular sequelae of chronic hypertension are due to large artery atherosclerosis, an equal number are due to small artery dysfunction. These microvascular complications include eye disease (retinopathy), kidney failure, diastolic dysfunction of the heart and small vessel brain disease leading to stroke syndromes, dementia and even depression.

Chronic kidney disease (CKD) affects around 10-13% of the general population, with only a small proportion in end stage renal disease (ESRD), either on dialysis or awaiting renal transplantation. It is well documented that CKD patients have an extremely high risk of developing cardiovascular disease (CVD) compared with the general population, so much so that in the early stages of CKD patients are more likely to develop CVD than they are to progress to ESRD. Various pathophysiological pathways and explanations have been advanced and suggested to account for this, including endothelial dysfunction, dyslipidaemia, inflammation, left ventricular hypertrophy and cardiac autonomic dysfunction.

Type 2 diabetes is associated with significant microvascular and macrovascular disease, with considerable impact on morbidity and mortality. Recent evidence has cast uncertainty on the benefits of very tight glycaemic goals in these individuals.

Conversely, these patients are in most need of the cardio- and renal protection offered by RAB. This reservation is mostly because of fear of precipitating acute renal deterioration.

We aimed to assess the effect of preoperative anaemia on 30-day postoperative morbidity and mortality in patients undergoing major non-cardiac surgery.
Methods: We analysed data for patients undergoing major non-cardiac surgery in 2008 from The American College of Surgeons' National Surgical Quality Improvement Program database (a prospective validated outcomes registry from 211 hospitals worldwide in 2008).
Background: Around 16% of all patients who present with atheromatous renovascular disease (ARVD) in the United States undergo revascularization. Historically, patients with advanced chronic kidney disease (CKD) have been considered least likely to show improvement in renal functional terms, or survival. We aimed to investigate whether differences in outcomes after revascularization compared to medical management might be observed in ARVD patients if stratified by their CKD classes.
View Article and Find Full Text PDFDiabetic individuals have a significantly increased likelihood of developing cardiovascular disease. Whilst part of this association is explained by the presence of concomitant risk factors, large epidemiological studies have consistently reported diabetes as a strong risk factor for the development of heart failure after adjusting for such covariates. This has resulted in the notion that there is a distinct cardiomyopathy specific to diabetes, termed 'diabetic cardiomyopathy'.

Abnormal increases of both wall thickness and lumen diameter are associated with an increased mortality. Changes to small artery structure in response to blood pressure (BP) in patients with type 1 diabetes mellitus have never been examined.
View Article and Find Full Text PDFDiabetic cardiomyopathy is a distinct primary disease process, independent of coronary artery disease, which leads to heart failure in diabetic patients. Epidemiological and clinical trial data have confirmed the greater incidence and prevalence of heart failure in diabetes. Novel echocardiographic and MR (magnetic resonance) techniques have enabled a more accurate means of phenotyping diabetic cardiomyopathy.
