Although the majority of thyroid nodules are benign process excluding malignancy is challenging and sometimes involves unnecessary surgical procedures. We explored development a predictive model for in by integrating combination simple demographic, biochemical, ultrasound characteristics.Retrospective case-record review. reviewed records patients with referred to our institution from 2004 2011 (n = 536; female 84 %, mean age 51 years). All was proven histologically while disease either...

Background Diagnostic errors are well documented in the literature and emphasise need to teach diagnostic skills at an early stage medical school create effective safe clinicians. Hence, there may be a place for aids (such as Surgical Sieve) that provide framework generating ideas about diagnoses. With repeated use of Sieve teaching sessions with students, prompted by traditional handheld wheels used antenatal clinics, we developed Compass Medicine, wheel comprising three concentric discs...

The assessment of coronary microvascular dysfunction (CMD) using invasive methods is a field growing interest, however the preferred method remains debated. Bolus and continuous thermodilution are commonly used methods, but weak agreement has been observed in patients with angina non-obstructive arteries (ANOCA). This study examined their revascularized acute syndromes (ACS) chronic (CCS) patients.

<h3>Background</h3> High intensity lipid lowering therapy decreases the risk of subsequent cardiovascular events following acute myocardial infarction and is recommended by National Institute for Clinical Excellence guidance. Diabetes another well-recognised factor increasing in prevalence globally. Importantly, recent clinical trials have demonstrated efficacy glucose-lowering therapies such as SGLT-2 inhibitors GLP-1 agonists modifying outcomes. <h3>Objective</h3> This quality improvement...

<h3>Background</h3> Despite growing evidence of its clinical implications, assessment coronary microvascular dysfunction (CMD) remains limited in routine practice. Hence, there is an increasing interest angiography-derived indices to encourage CMD the cardiac catheterisation laboratory. We investigate here a novel approach, IMRhybrid, using combination pressure-wire-based distal pressure (Pd) and surrogate flow. <h3>Methods</h3> Patients enrolled as part Oxford Acute Myocardial Infarction...

Hence, there is an increasing interest angiography‐derived indices to encourage CMD the cardiac catheterisation laboratory. Aims We investigate here alternative approach, using a combination pressure‐wire‐based distal pressure (P d ) and surrogate flow, derive hybrid index microcirculatory resistance (IMR ).

Introduction Chemotherapy induced cardiomyopathy (CIC) carries significant morbidity and mortality in cancer survivors. Female sex is a recognised risk factor for CIC paediatric populations but the effect of adult patients has not been established. We investigated differences using cardiovascular magnetic resonance (CMR). Method 76 without abnormal left ventricular function prior to chemotherapy (30 male [59±15 years], 46 female [58±13 years, p=0.86]) were included. Cumulative anthracycline...
