RESUMO
Nicotine is the psychoactive component given tobacco has several main components and acts as an agonist for nicotinic acetylcholine receptors (nAChRs) in the nervous system. Although the ligand-gated cation channels known as nAChRs are found throughout the nervous system and body, this review focuses on neuronal nAChRs. Individuals with psychiatric diseases such as schizophrenia, comorbid substance use disorders, attention-deficit hyperactivity disorder, major depression, and bipolar disorder have increased rates of smoking. These psychiatric disorders are associated with various cognitive deficits, including working memory, deficits in attention, and response inhibition functions. The cognitive-enhancing effects of nicotine may be particularly relevant predictors of smoking initiation and continuation in this comorbid population. Individuals with schizophrenia make up a significant proportion of smokers. Literature suggests that patients smoke to alleviate cognitive deficiencies due to the stimulating effects of nicotine. This narrative review examines the role of nicotine on cognition in schizophrenia.
RESUMO
Selecting anticoagulation therapy for patients with atrial fibrillation and coronary artery disease has always been challenging for physicians. The treatment modalities have evolved with time. Oral anticoagulation with warfarin was used in the initial era of stenting to prevent stent thrombosis, and dual antiplatelet therapy is the current recommendation. Triple anticoagulation therapy, i.e., aspirin, P2Y12 inhibitor, and oral anticoagulation, is associated with higher bleeding episodes and mortality compared to the combination of an anticoagulant and a P2Y12 inhibitor.
RESUMO
Introduction ST-elevation myocardial infarction (STEMI) is a serious manifestation of coronary artery disease and remains a significant contributor to morbidity and mortality worldwide. To reduce the risk of recurrent cardiovascular disease (CVD) events, the American College of Cardiology (ACC) and American Heart Association (AHA) recommend the use of five classes of medications after acute coronary syndrome (ACS). The purpose of this study was to evaluate whether STEMI patients admitted to our community hospital were discharged on optimal medical therapy based on the latest AHA/ACC guidelines. Methods A retrospective, single-center electronic medical records review was conducted at our community hospital between July 2017 and December 2018. Patients included in the study were admitted to our hospital through the emergency department as STEMI alerts. We reviewed the discharge prescriptions and assessed compliance with the medication regimen endorsed by AHA/ACC, which includes aspirin, P2Y12 inhibitors, ß-blockers, angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs), and statins. Results A total of 147 patients were included in our study. The mean age of our study population was 62 ± 12.48 years. 97.2% of all patients with STEMI underwent coronary angiography. Hypertension (65.9%) was the most common comorbidity followed by hyperlipidemia (54.42%), diabetes mellitus (29.25%), and history of coronary artery disease (CAD) (24.48%). Among patients with successful reperfusion, 87.4% of the patients received the combination of four guideline-directed medical therapy (GDMT) (comprising dual antiplatelet therapy, a ß-blocker, and a statin) and 57% were discharged on five guideline-directed medical treatment (the combination of dual antiplatelet therapy, a ß-blocker, an ACEIs or an ARB, and a statin). Conclusion Optimal secondary prevention medications are known to be effective in reducing the risk of repeat ischemic events in ACS. This study demonstrated that adherence to GDMT in our community-based hospital study is better compared to prior studies but remained suboptimal. Potential strategies to improve adherence to guidelines are necessary.
