A Case of Complex Percutaneous Coronary Intervention for ST Elevation Myocardial Infarction Caused by Extension of Type A Aortic Dissection into the Left Main Coronary Artery.

Aortic dissection extending into the left main coronary artery is rare and carries high mortality, especially when resulting in extensive myocardial infarction. Here we report a case of retrograde extension of type A aortic dissection into the left main coronary artery causing ST-segment elevation myocardial infarction managed by complex percutaneous coronary intervention, which resulted in temporary stabilization of the patient. We briefly review current literature on this approach.

Predicting the Unknown and the Unknowable. Are Anthropometric Measures and Fitness Profile Associated with the Outcome of a Simulated CrossFit Competition?

The main objective of this research was to find associations between the outcome of a simulated CrossFit competition, anthropometric measures, and standardized fitness tests. Ten experienced male CrossFit athletes (age 28.8 ± 3.

RF Energy Absorption in Human Bodies Due to Wearable Antennas in the 2.4 GHz Frequency Band.

Human exposure to electromagnetic fields produced by two wearable antennas operating in the 2.4 GHz frequency band was assessed by computational tools. Both antennas were designed to be attached to the skin, but they were intended for different applications.

Autologous hematopoietic stem cell transplantation in a patient with refractory seropositive myasthenia gravis: A case report.

Myasthenia gravis is a neuromuscular autoimmune disease characterized by fatigable weakness of skeletal muscles that results from an antibody-mediated immunological attack directed at acetylcholine postsynaptic receptors. Autologous hematopoietic stem cell transplantation is considered as a treatment option in refractory cases of myasthenia gravis. A 56-year-old Colombian male presented with six months of progressive hoarseness and dysphagia, with a positive repetitive stimulation test suggestive of end plate neuromuscular disease.

Association Between Electronic Cigarette Use and Myocardial Infarction.

Introduction: Electronic cigarettes (e-cigarettes) are promoted as a less risky alternative to conventional cigarettes and have grown in popularity. Experimental and clinical evidence suggests that they could increase the risk of myocardial infarction.

Methods: The National Health Interview Surveys of 2014 (n=36,697) and 2016 (n=33,028) were used to examine the cross-sectional association between e-cigarette use (never, former, some days, daily) and cigarette smoking (same categories) and myocardial infarction in a single logistic regression model that also included demographics (age, gender, BMI) and health characteristics (hypertension, diabetes, and hypercholesterolemia) using logistic regression.

[Wernicke´s encephalopathy and polyneuropathy associated with vitamin B complex deficiency after a bariatric surgery].

Bariatric surgery is a treatment that guarantees a substantial and lasting weight loss in addition to the tangible benefits relating to obesity-associated medical conditions. The increasing number of bariatric surgeries has revealed an increasing number of complications related to this procedure, including Wernicke´s encephalopathy and vitamin B deficiency polyneuropathies. Herein, a 7-week post-surgery case of Wernicke´s encephalopathy is presented that emphasizes the importance of an early recognition of these symptoms so as to initiate intervention during the reversible phase of these potentially lethal pathologies.

[Risk factors associated with the prevalence of arterial hypertension in adults in Bucaramanga, Colombia].

Objective: To assess the prevalence of high blood pressure (PHBP) and its association with age, sex, socioeconomic status (SES), and body mass index (BMI = kg/m2).

Material And Methods: A cross-sectional survey was carried out in 1996, in a random sample of 356 adults aged 20 and older, residents of Bucaramanga, Colombia. Weight, height, and blood pressure readings were obtained, plus data on age and gender.
