Social bias in artificial intelligence algorithms designed to improve cardiovascular risk assessment relative to the Framingham Risk Score: a protocol for a systematic review
This study will employ an equity-lens to identify sources of bias (ie, race/ethnicity, gender and social stratum) in ML algorithms designed to improve CVD risk assessment relative to the FRS. A comprehensive literature search will be completed using MEDLINE, Embase and IEEE to answer the research question: do AI algorithms that are designed for the estimation of CVD risk and that compare performance with the FRS address the sources of bias inherent in the FRS? No study date filters will be imposed on the search, but English language filters will be applied. Studies describing a specific algorithm or ML approach that provid...

Prevalence of atrial fibrillation in Northern Sri Lanka: a study protocol for a cross-sectional household survey
This study was approved by the Ethics Review Committee of Faculty of Medicine at University of Jaffna. Written informed consent will be obtained from all participants. Findings will be disseminated through publication in a peer-reviewed journal and presentations at conferences. The findings will enable early treatment for new AF diagnoses and inform interventions to improve community-based management of AF in LMICs.

Life-threatening complications of hyperemesis gravidarum
Exp Ther Med. 2021 Jun;21(6):642. doi: 10.3892/etm.2021.10074. Epub 2021 Apr 16.ABSTRACTHyperemesis gravidarum (HG) refers to severe nausea and emesis noted during pregnancy. However, no consensus exists on the specific diagnostic criteria that can be used for this condition. The aim of the present systematic review was to summarize the available evidence regarding the severe complications observed during HG with a heightened risk of fatality. A systematic search was conducted on PubMed, Cochrane Library, EMBASE and WILEY databases for the relevant publications regarding the severe and life-threatening complications of HG....

Potassium binders for chronic hyperkalaemia in people with chronic kidney disease.
CONCLUSIONS: Evidence supporting clinical decision-making for different potassium binders to treat chronic hyperkalaemia in adults with CKD is of low certainty; no studies were identified in children. Available studies have not been designed to measure treatment effects on clinical outcomes such as cardiac arrhythmias or major GI symptoms. This review suggests the need for a large, adequately powered study of potassium binders versus placebo that assesses clinical outcomes of relevance to patients, clinicians and policy-makers. This data could be used to assess cost-effectiveness, given the lack of definitive studies and t...

How Did Medtronic ’s HVAD Perform in LATERAL Trial?
Medtronic’s HeartWare HVAD pump system could get a significant boost after performing well in the LATERAL clinical trial. The Dublin-based company presented results from the study at the American Society for Artificial Internal Organs 65th Annual Conference, that showed patients who received the system had 95% freedom from disabling stroke at two years. The medtech giant now plans to launch a global registry to collect additional clinical evidence to further characterize survival, adverse events, and economic benefits of the HVAD System. The HVAD Pump is a left ventricle assist device (LVAD) approved in t...

Asymptomatic Carotid Stenosis Is Associated With Circadian and Other Variability in Embolus Detection
Conclusions: Embolism associated with asymptomatic carotid stenosis shows circadian variation with highest rates 4–6 h before midday. This corresponds with peak circadian incidence of stroke and other vascular complications. These and ASED Study results show that monitoring frequency, duration, and time of day are important in ES detection. Introduction Transcranial Doppler (TCD) detected microembolism in the ipsilateral middle cerebral artery (MCA) may help stratify the risk of stroke and other arterial disease complications in persons with advanced (≥60%) asymptomatic carotid stenosis. If so, this t...

Restrictive Versus Liberal Red Blood Cell Transfusion for Cardiac Surgery: A Systematic Review and Meta-Analysis of Randomized Controlled Trials
Conclusion:This meta-analysis showed that restrictive strategies for RBC transfusion are as safe as liberal strategies in patients undergoing cardiac surgery.Key points:Restrictive strategies for red blood cell transfusion are as safe as liberal approaches in patients undergoing cardiac surgery.Longer duration of stay in the intensive care unit is more common in patients managed with a restrictive transfusion approach. However, the overall hospital length of stay appeared to be similar between both groups.Further studies are needed to ascertain threshold triggers for RBC transfusion.Figure.DisclosuresHassan: abott: Other: ...

Can catheter ablation reduce the incidence of thromboembolic events in patients with atrial fibrillation?: Protocol for a systematic review and meta-analysis
Abstract Atrial fibrillation (AF), the most common cardiac arrhythmia, is a major risk factor for thromboembolic events, especially ischemic stroke. Catheter ablation is an effective method to maintain sinus rhythm in patients with AF. Although some observational studies have shown a relatively lower stroke rate after catheter ablation, whether catheter ablation can reduce the thromboembolic risk in patients with AF remains unclear. We aim to perform a systematic review to determine whether catheter ablation can prevent thromboembolism in patients with AF. PubMed, Embase, the Web of Science, and the Cochrane Library wil...

Symptom burden, Metabolic profile, Ultrasound findings, Rhythm, neurohormonal activation, haemodynamics and health-related quality of life in patients with atrial Fibrillation (SMURF): a protocol for an observational study with a randomised interventional component
Introduction Atrial fibrillation (AF) is the most common cardiac arrhythmia, with an estimated prevalence of 1.5–2%. It is an independent risk factor for ischaemic stroke and is estimated to cause about 20–25% of all stroke cases. AF has a great impact on health-related quality of life (HRQoL); however, one unresolved issue related to AF is the wide variation in its symptoms. Methods and analysis The symptom burden, metabolic profile, ultrasound findings, rhythm, neurohormonal activation, haemodynamics and HRQoL in patients with AF (Symptom burden, Metabolic profile, Ultrasound findings, Rhythm, neurohormonal ...

CASE 9—2015 Anesthetic Management of a Patient With Esophago-Pericardial Fistula Complicating Atrial Fibrillation Radiofrequency Ablation
ATRIAL FIBRILLATION (AF) REMAINS the most common arrhythmia in the elderly population.1,2 Treatment of AF is tailored toward rhythm and heart rate control using antiarrhythmic medications and anticoagulation therapy to prevent embolic stroke. However, antiarrhythmic therapy fails in a significant number of patients. Drug-refractory AF currently is managed with catheter ablation (CA) procedures, which are associated with a complication rate of about 5% and a mortality rate of approximately 0.001%.

Seattle in Deep Sleep This Week
Seattle wasn't sleepless this week. Not after more than 4,000 sleep experts from around the world descended upon the Emerald City for SLEEP 2015, an annual conference sponsored by the American Academy of Sleep Medicine and the Sleep Research Society. Topics and research on all things related to sleep -- how much we need, how much we don't get, how much is disrupted by undiagnosed sleep disorders and how a better, cheaper, less obtrusive way to detect sleep apnea is needed -- were discussed. "Right now we don't have enough sleep clinics, sleep laboratories and sleep specialists in the country to address all the sleep apn...
