Computed Tomography Coronary Angiography Is Feasible and Reliable for Proximal Coronary Segment Interpretation in Patients with Elevated Body Mass Index.

Computed tomography coronary angiography (CTCA) is under-utilised in detecting coronary artery disease (CAD) in obese patients due to concerns about non-evaluable testing. We hypothesise that these concerns are predominantly related to smaller and branch coronary vessels, and CTCA remains adequate for proximal segment stenosis interpretation, which has significant clinical implications. This retrospective cohort study, on consecutive patients referred for CTCA for suspected CAD, grouped patients by body mass index.

Bilateral adrenal hemorrhage in a postpartum woman with multiple thromboemboli: A case report.

Background: Bilateral adrenal hemorrhage is a rare but often a fatal cause of primary adrenal insufficiency that can result in adrenal crisis if not identified and managed appropriately.

Case Presentation: We present a case of a 27-year-old Caucasian female who was admitted to the hospital 17 days postpartum with pleuritic chest and flank pain, shortness of breath and nausea. Computed tomography imaging confirmed multiple thromboemboli including pulmonary emboli and noted bilateral bulky adrenal glands.

Cardiology patients are unaware of the benefits of seasonal influenza immunization.

Unlabelled: Seasonal influenza immunization reduces the risk of cardiovascular events. Patients with established cardiovascular disease (CVD) derive a greater benefit than those without, yet up to 50 % do not take up the immunization. Patient perceptions and beliefs are known to inform immunization behaviors, yet the immunization related beliefs of patients with CVD have not been described.

Variation of computed tomography-derived extracellular volume fraction and the impact of protocol parameters: A systematic review and meta-analysis.

Background: Cardiac computed tomography quantification of extracellular volume fraction (CT-ECV) is an emerging biomarker of myocardial fibrosis which has demonstrated high reproducibility, diagnostic and prognostic utility. However, there has been wide variation in the CT-ECV protocol in the literature and useful disease cut-offs are yet to be established. The objectives of this meta-analysis were to describe mean CT-ECV estimates and to estimate the effect of CT-ECV protocol parameters on between-study variation.

bone marrow infection in an immunocompetent patient.

Background: We discuss a case of an immunocompetent patient who presented with fever and tachypnoea, found to have bone marrow infection, cultured on bone marrow aspirate sample. is an opportunistic yeast pathogen that typically affects immunocompromised individuals, or occurs in patients with apparent introduced source; neither of these factors were present for this case. Bone marrow aspirates and trephines are not regular investigations for fever; however they can be useful diagnostic aids as evidenced in this case.

Surveillance MRI is associated with improved survival in patients with primary sclerosing cholangitis.

Background: The benefits of regular surveillance imaging for cholangiocarcinoma in patients with primary sclerosing cholangitis (PSC) are unclear. Hence, we aimed to evaluate the impact of regular magnetic resonance cholangiopancreatography (MRCP) on outcomes of patients with PSC in Australia, where the practice of MRCP surveillance is variable.

Methods: The relationship between MRCP surveillance and survival outcomes was assessed in a multicenter, retrospective cohort of patients with PSC from 9 tertiary liver centers in Australia.

Optimal Medical Therapy for Stable Ischemic Heart Disease in 2024: Focus on Blood Pressure and Lipids.

Hypertension and dyslipidemia are 2 highly prevalent and modifiable risk factors in patients with stable ischemic heart disease. Multiple lines of evidence demonstrate that lowering blood pressure and low-density lipoprotein cholesterol improves clinical outcomes in patients with ischemic heart disease. Accordingly, clinical guidelines recommend intensive treatment targets for these high-risk patients.

Perspectives on the success of plasma lipidomics in cardiovascular drug discovery and future challenges.

Introduction: Plasma lipidomics has emerged as a powerful tool in cardiovascular drug discovery by providing insights into disease mechanisms, identifying potential biomarkers for diagnosis and prognosis, and discovering novel targets for drug development. Widespread application of plasma lipidomics is hampered by technological limitations and standardization and requires a collaborative approach to maximize its use in cardiovascular drug discovery.

Areas Covered: This review provides an overview of the utility of plasma lipidomics in cardiovascular drug discovery and discusses the challenges and future perspectives of this rapidly evolving field.

How Will Our Practice Change After the CLEAR Outcomes Trial?

Purpose Of Review: Bempedoic acid is a novel therapeutic agent that is designed to reduce levels of low-density lipoprotein cholesterol (LDL-C). The purpose of this review is to provide the background for development of bempedoic acid, findings from clinical trials and to discuss clinical implications.

Recent Findings: Bempedoic acid inhibits ATP citrate lyase within the liver and reduces cholesterol synthesis, with the potential to avoid muscle symptoms experienced by patients treated with statins.

Cardiologists' knowledge and perceptions of the seasonal influenza immunisation.

Background: Seasonal influenza immunisation reduces cardiovascular events in high-risk patients, but 50% do not receive routine immunisation. The perceptions and current role of cardiologists in recommending and prescribing influenza immunisation has not been well described.

Methods: We used an exploratory sequential mixed methods design.

Respite care models and practices for persons with intellectual disability: A scoping review.

Background: Families are the primary caregivers for persons with intellectual disability (ID), offering informal support to ensure community living. Ensuring families are adequately supported is key to reduce the financial, physical, mental and social toll which long-standing inadequately supported care giving may evoke. Respite care is such a support service offered to caregivers and care-recipients with ID.

Impact of PCSK9 inhibitors on coronary atheroma phenotype following myocardial infarction: insights from intravascular imaging.

Purpose Of Review: The aim of this study was to review the impact of combination lipid lowering with statins and proprotein convertase subtilisin kexin type 9 (PCSK9) inhibitors on coronary atherosclerosis using serial intravascular imaging.

Recent Findings: Early studies using intravascular ultrasound established the ability of increasingly intensive lipid lowering to both slow progression and ultimately promote regression of coronary disease. More recent clinical trials that have employed serial imaging with optical coherence tomography have permitted the ability to evaluate the impact of intensive lipid lowering on compositional features associated with plaque vulnerability.

Severe Adult Rotavirus Gastroenteritis: A Rare Case with Multi-Organ Failure and Critical Management.

BACKGROUND Infectious diarrheal illnesses such as rotavirus gastroenteritis are significant contributors to childhood morbidity and mortality, especially in low socio-demographic index regions. Major advances in addressing this issue include sanitation and clean water initiatives, as well as rotavirus immunization. In Australia, a robust vaccination program has significantly reduced childhood rotavirus infections, leading to decreased hospitalizations and mortality.

Provocation testing in congenital long QT syndrome: A practical guide.

Congenital long QT syndrome (LQTS) is a hereditary cardiac channelopathy with an estimated prevalence of 1 in 2500. A prolonged resting QT interval corrected for heart rate (QTc interval) remains a key diagnostic component; however, the QTc value may be normal in up to 40% of patients with genotype-positive LQTS and borderline in a further 30%. Provocation of QTc prolongation and T-wave changes may be pivotal to unmasking the diagnosis and useful in predicting genotype.

Knowledge, beliefs and practices of nurses with long-acting reversible contraception, Cape Town.

Background: Implanon and copper intrauterine contraceptive device (IUCD) are long-acting reversible contraceptives (LARC) available in public primary health care (PHC) South Africa. These methods are the most effective forms of contraception.

Aim: To evaluate the knowledge, beliefs and practices on provision of LARC.

Tackling the First COVID-19 Wave at the Cape Town Hospital of Hope: Why Was It Such a Positive Experience for Staff?

: In contrast to alarming reports of exhaustion and burnout amongst healthcare workers in the first wave of the COVID-19 pandemic, we noticed surprisingly positive staff experiences of working in a COVID-19 field hospital in South Africa. The 862-bed "Hospital of Hope" was established at the Cape Town International Convention Centre specifically to cope with the effects of the first wave of the COVID-19 pandemic in Cape Town. : We aimed to systematically describe and assess the effects on staff and the local health system.

Prescribing Trends and Health Care Expenditure of P2Y Prescriptions in Australia Over the Last Decade.

Background: Dual antiplatelet therapy (DAPT) is guideline therapy following acute coronary syndrome (ACS). Novel, potent P2Y inhibitors have been developed and studied but it is unclear how this evidence has been incorporated into patient care. We sought to describe the prescribing trends and health care costs of P2Ytherapy in Australia over the last decade.

Epidemiology and outcomes of primary sclerosing cholangitis: an Australian multicentre retrospective cohort study.

Background And Aims: Little is known regarding the epidemiology and outcomes of patients with primary sclerosing cholangitis (PSC) in Australia. We, therefore, evaluated the epidemiology and clinical outcomes of PSC in a large cohort of Australian patients and compared these to the general population.

Methods: We conducted a multicentre, retrospective cohort study of PSC patients at nine tertiary liver centers across three Australian states, including two liver transplant centers.

Comparative Validity of the American Speech-Language-Hearing Association's National Outcomes Measurement System, Functional Oral Intake Scale, and G-Codes to Mann Assessment of Swallowing Ability Scores for Dysphagia.

Background The American Speech-Language-Hearing Association (ASHA) advocates using the National Outcomes Measurement System (NOMS) scales to assist speech-language pathologists (SLPs) in the mandated assigning of "functional limitation levels" and G-Code for Medicare Part B claims. Unfortunately, not all SLPs have access to this tool, and it is unclear how other common outcome measurement scales relate to ASHA NOMS or G-Codes. To explore the utility of other scales in reporting Centers for Medicare & Medicaid Services G-Codes, we conducted a comparative validity study comparing ASHA NOMS Dysphagia Scale, Functional Oral Intake Scale (FOIS), and Mann Assessment of Swallowing Ability to G-Codes on a sample of 105 patients who had stroke.
