Effects of aspirin and omega-3 fatty acids on composite and subdomain scores from the NEI-VFQ-25 questionnaire: the ASCEND-Eye randomized controlled trial.

Background: The double-blind, 2 × 2 factorial design, placebo-controlled ASCEND randomized trial compared the effects of 100 mg aspirin daily and, separately, 1 g omega-3 fatty acids (FAs) daily on the primary prevention of cardiovascular disease in 15,480 UK adults with diabetes. We report the effects of these randomized treatment allocations on scores derived from the National Eye Institute's Visual Function Questionnaire-25 (NEI-VFQ-25) in a subset of participants involved in the ASCEND-Eye sub-study.

Methods: Ordinal data from the NEI-VFQ-25 were analyzed using proportional odds regression methods.

Conventional and genetic associations of BMI with major vascular and non-vascular disease incidence and mortality in a relatively lean Chinese population: U-shaped relationship revisited.

Background: Higher body mass index (BMI) is associated with higher incidence of cardiovascular and some non-cardiovascular diseases (CVDs/non-CVDs). However, uncertainty remains about its associations with mortality, particularly at lower BMI levels.

Methods: The prospective China Kadoorie Biobank recruited >512 000 adults aged 30-79 years in 2004-08 and genotyped a random subset of 76 000 participants.

The Princeton IV Consensus Recommendations for the Management of Erectile Dysfunction and Cardiovascular Disease.

The Princeton Consensus (Expert Panel) Conference is a multispecialty collaborative symposium dedicated to optimizing sexual function and preserving cardiovascular health. The Fourth Princeton Consensus Conference was convened on March 10-11, 2023, at the Huntington Medical Research Institutes in Pasadena, California. Princeton panels I to III addressed the clinical management of men with erectile dysfunction (ED) who also had cardiovascular disease.

Safety of topical sildenafil cream, 3.6% in a randomized, placebo-controlled trial for the treatment of female sexual arousal disorder.

Background: There are currently no Food and Drug Administration-approved treatments for female sexual arousal disorder (FSAD), which is physiologically analogous to male erectile dysfunction.

Aims: The study sought to test the systemic and local genital safety of topical sildenafil cream, 3.6% (sildenafil cream) among healthy premenopausal women with FSAD and their sexual partners over a 12-week treatment period.

Proceedings of PRINCETON IV: PDE5 inhibitors and cardiac health symposium.

Introduction: Prior consensus meetings have addressed the relationship between phosphodiesterase type 5 (PDE5) inhibition and cardiac health. Given significant accumulation of new data in the past decade, a fourth consensus conference on this topic was convened in Pasadena, California, on March 10 and 11, 2023.

Objectives: Our meeting aimed to update existing knowledge, assess current guidelines, and make recommendations for future research and practice in this area.

A comprehensive analysis of APOE genotype effects on human brain structure in the UK Biobank.

Alzheimer's disease (AD) risk is increased in carriers of the apolipoprotein E (APOE) ε4 allele and decreased in ε2 allele carriers compared with the ε3ε3 genotype. The aim of this study was to determine whether: the APOE genotype affects brain grey (GM) or white matter (WM) structure; and if differences exist, the age when they become apparent and whether there are differential effects by sex. We used cross-sectional magnetic resonance imaging data from ~43,000 (28,494 after pre-processing) white British cognitively healthy participants (7,446 APOE ε4 carriers) aged 45-80 years from the UK Biobank cohort and investigated image-derived phenotypes (IDPs).

Accuracy of heart failure ascertainment using routinely collected healthcare data: a systematic review and meta-analysis.

Background: Ascertainment of heart failure (HF) hospitalizations in cardiovascular trials is costly and complex, involving processes that could be streamlined by using routinely collected healthcare data (RCD). The utility of coded RCD for HF outcome ascertainment in randomized trials requires assessment. We systematically reviewed studies assessing RCD-based HF outcome ascertainment against "gold standard" (GS) methods to study the feasibility of using such methods in clinical trials.

Thromboxane biosynthesis and future events in diabetes: the ASCEND trial.

Background And Aims: Thromboxane (TX) A2, released by activated platelets, plays an important role in atherothrombosis. Urinary 11-dehydro-TXB2 (U-TXM), a stable metabolite reflecting the whole-body TXA2 biosynthesis, is reduced by ∼70% by daily low-dose aspirin. The U-TXM represents a non-invasive biomarker of in vivo platelet activation and is enhanced in patients with diabetes.

ASCEND-Eye: Effects of Aspirin on Diabetic Retinopathy.

Purpose: Preclinical studies support a protective role for aspirin in early diabetic retinopathy (DR), but the findings from randomized trials are limited. We present randomized evidence for the efficacy and safety of aspirin on DR outcomes.

Design: A substudy of the A Study of Cardiovascular Events in Diabetes (ASCEND) double-masked, randomized, placebo-controlled trial of 100 mg aspirin daily for the primary prevention of serious cardiovascular events in people with diabetes.

Princeton IV consensus guidelines: PDE5 inhibitors and cardiac health.

Background: In 1999, 1 year after the approval of the first oral phosphodiesterase type 5 (PDE5) inhibitor for the treatment of erectile dysfunction (ED), the first Princeton Consensus Conference was held to address the clinical management of men with ED who also had cardiovascular disease. These issues were readdressed in the second and third conferences. In the 13 years since the last Princeton Consensus Conference, the experience with PDE5 inhibitors is more robust, and recent new data have emerged regarding not only safety and drug-drug interactions, but also a potential cardioprotective effect of these drugs.

ASCEND-Eye: Effects of Omega-3 Fatty Acids on Diabetic Retinopathy.

Purpose: Preclinical studies support a protective role for omega-3 fatty acids (FAs) on diabetic retinopathy (DR), but these observations have not been confirmed in randomized trials. We present randomized evidence for the effects of omega-3 FAs on DR outcomes.

Design: A substudy of the A Study of Cardiovascular Events iN Diabetes (ASCEND) double-blind, randomized, placebo-controlled trial of 1 g omega-3 fatty acids (containing 460 mg eicosapentaenoic acid and 380 mg docosahexaenoic acid) daily for the primary prevention of serious cardiovascular events, in 15 480 UK adults at least 40 years of age, with diabetes.

MTHFR and risk of stroke and heart disease in a low-folate population: a prospective study of 156 000 Chinese adults.

Background: The relevance of folic acid for stroke prevention in low-folate populations such as in China is uncertain. Genetic studies of the methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism, which increases plasma homocysteine (tHcy) levels, could clarify the causal relevance of elevated tHcy levels for stroke, ischaemic heart disease (IHD) and other diseases in populations without folic acid fortification.

Methods: In the prospective China Kadoorie Biobank, 156 253 participants were genotyped for MTHFR and 12 240 developed a stroke during the 12-year follow-up.

ASCEND-Eye: Rationale, design and baseline characteristics for a sub-study of the ASCEND randomised trial, exploring the effects of aspirin and omega-3 fatty acids on diabetic retinopathy and age-related macular degeneration.

Background: Aspirin and omega-3 fatty acids (FAs) have potential disease-modifying roles in diabetic retinopathy (DR) and age-related macular degeneration (AMD), but randomized evidence of these effects is limited. We present the rationale and baseline characteristics of ASCEND-Eye, a sub-study of the double-blind, 2x2 factorial design, randomized placebo-controlled ASCEND (A Study of Cardiovascular Events iN Diabetes) trial of 100 mg aspirin daily and, separately, 1g omega-3 FAs daily for the primary prevention of serious cardiovascular events, in 15,480 British adults, aged 40 years or older with diabetes.

Methods: Eye events will be derived from three sources: 1) participant follow-up questionnaires from ASCEND, 2) electronic NHS Diabetic Eye Screening Programme (DESP) data and 3) responses to the National Eye Institute's Visual Function Questionnaire-25 (NEI-VFQ-25) sent to a subset of participants after the main trial ended.

Testosterone use for hypoactive sexual desire disorder in postmenopausal women.

Testosterone is an important evidence-based therapy for hypoactive sexual desire disorder (HSDD) in postmenopausal women. Clinical practice guidelines based on the most comprehensive meta-analysis of benefits and risks of testosterone therapy to date state that the sole evidence-based indication for testosterone therapy is HSDD in postmenopausal women. The guidelines also provide recommendations regarding identification of patients, dosing, monitoring, and follow-up.

Reliability of major bleeding events in UK routine data versus clinical trial adjudicated follow-up data.

Objective: To assess how reliable UK routine data are for ascertaining major bleeding events compared with adjudicated follow-up.

Methods: The ASCEND (A Study of Cardiovascular Events iN Diabetes) primary prevention trial randomised 15 480 UK people with diabetes to aspirin versus matching placebo. The primary safety outcome was major bleeding (including intracranial haemorrhage, sight-threatening eye bleeding, serious gastrointestinal bleeding and other major bleeding (epistaxis, haemoptysis, haematuria, vaginal and other bleeding)) ascertained by direct-participant mail-based follow-up, with >90% of outcomes undergoing adjudication.

Physical disability and venous thromboembolism during pregnancy and the postpartum period: a population-based cohort study.

Background: Pregnancy and the postpartum period are a high-risk time for venous thromboembolism (VTE). Decreased mobility is also a major risk factor. However, the risk of peripregnancy VTE among individuals with physical disabilities is unknown.

Clinician-reported barriers to providing perinatal care to women with intellectual and developmental disabilities.

Background: Research suggests that women with intellectual and developmental disabilities are at increased risk for adverse pregnancy outcomes. Further, they report unmet perinatal care needs. This qualitative study examined clinician perspectives on barriers to providing perinatal care to women with intellectual and developmental disabilities.

Premenstrual dysphoric disorder and sexual function: a narrative review.

Introduction: Premenstrual dysphoric disorder (PMDD) and female sexual dysfunction (FSD) are 2 prevalent illnesses in women that cause distress and affect quality of life. There are plausible biological, social, and psychological links between these 2 conditions. Nevertheless, few studies have examined sexual function in women with PMDD.

Prenatal Care Experiences of Childbearing People With Disabilities in Ontario, Canada.

Objective: To explore the care experiences of childbearing people with physical, sensory, and/or intellectual/developmental disabilities during pregnancy.

Design: Descriptive qualitative.

Setting: Ontario, Canada, where physician and midwifery care during pregnancy are provided at no direct cost to residents.

Unmet needs, limited access: A qualitative study of postpartum health care experiences of people with disabilities.

Aim: To understand the postpartum care received by birthing people with disabilities and their newborns, from their own perspectives.

Design: A qualitative study with semi-structured interviews.

Methods: Between July 2019 and February 2020, in-person and virtual interviews were conducted with 31 people with physical, sensory, and intellectual/developmental disabilities in Ontario, Canada, about the formal inpatient and outpatient services and supports they used in the first few months after they gave birth.

Effect of low-dose aspirin on urinary 11-dehydro-thromboxane B2 in the ASCEND (A Study of Cardiovascular Events iN Diabetes) randomized controlled trial.

Background: Aspirin is widely used for cardioprotection with its antiplatelet effects due to the blocking of thromboxane A2 production. However, it has been suggested that platelet abnormalities in those with diabetes prevent adequate suppression with once daily aspirin.

Methods: In the ASCEND randomized double-blind trial of aspirin 100 mg once daily versus placebo in participants with diabetes but no history of cardiovascular disease, suppression was assessed by measuring 11-dehydro-thromboxane B2 excretion in urine (U-TXM) in a randomly selected sample of 152 participants (76 aspirin arm, 74 placebo arm), plus 198 (93 aspirin arm, 105 placebo arm) adherent to study drugs and selected to maximize the numbers ingesting their last tablet 12-24 h before urine sampling.
