Propofol is the most widely used short-acting intravenous anesthetic in clinical practice. Existing studies have shown that propofol has many effects on the cardiovascular system in addition to its anesthetic effect. Propofol can antagonize a variety of tachyarrhythmias and reduce the risk of recurrence, regulate autonomic balance of the heart, modulate circulatory dynamics, thereby increasing blood perfusion to vital organs such as the kidney, intestine, and brain, and exert myocardial protection and cerebral protection during ischemia-reperfusion injury. In this paper, we review the potential mechanisms of these effects and provide and ideas for future research and novel drug development of propofol and its derivatives in cardiac electrophysiology and circulatory dynamics.

Cardiovascular diseases are the leading cause of death globally. As cardiovascular risk factors continuously rise to pandemic levels, there is intense pressure worldwide to improve cardiac care in preventive cardiology, cardio-diagnostics, therapeutics, and interventional cardiology. ⋯ This is especially daunting for LMICs who are already plagued with a high burden of infectious disease, unemployment, physician burnt, brain drain, and a developing cardiac practice. Should the focus of cardiovascular care be on men or machines? Is the technology sustainable in a low-resource setting? What lessons did we learn from the COVID-19 pandemic? We attempt to zero in on the dilemmas of AI in the Nigerian setting including AI acceptance, the bottlenecks of cardiology practice in Nigeria, the role of AI, and the type of AI that may be adapted to strengthen cardiovascular care of Nigerians.

The near total absence of routine Hepatitis Delta Virus (HDV) screening in many countries in sub-Saharan Africa is a major challenge to understanding the burden of HDV in the region. ⋯ The study showed a high level of awareness of HDV dependency on HBV, for natural infection to occur. However, it documented very minimal HDV screening in clinical settings and factors affecting screening among clinicians.

Positive T-wave polarity in the augmented vector right lead (Tw-aVR) and ST-segment deviation in the augmented vector right lead (STaVR) have been identified as potential predictors of adverse outcomes in various cardiac conditions. ⋯ Positive Tw-aVR and STaVR were found to be associated with in-hospital mortality in HFrEF patients after CABG. These findings suggest that identifying patients with positive Tw-aVR and STaVR may help identify those at higher risk of adverse outcomes and facilitate closer monitoring and more aggressive interventions.

Comparative Study
New Solution in the Treatment of Children with Class II Malocclusion: Biblock Appliance.
A new design, the Biblock appliance, was developed for the functional treatment of Class II malocclusions. ⋯ The effects of AA, an appliance accepted by the orthodontic community, and BA, a new design, on the skeletal, dentoalveolar, and soft tissue were similar.
