Abstract

Introduction: There is a lack of data on the characteristics of teenagers admitted with acute myocardial infarction (AMI). Recent studies have hinted that with changes in lifestyle and easier access to substances of abuse, people may be prone to several cardiovascular complications at an earlier age. Material and methods: Our analysis was based on the 2016-2020 National Inpatient Samples. Logistic models allowed us to investigate the adjusted odds ratios (aOR) of AMI among teenagers. We explored outcomes and complications such as cardiogenic shock, extracorporeal membrane oxygenation (ECMO), coronary artery bypass graft surgery (CABG), percutaneous coronary intervention (PCI), and mortality in these patients. Results: A total of 2170 cases of AMI were recorded between 2016 and 2020 (53.3 cases per 100,000 admissions among teenagers). Weekend admissions (26.3% vs. 20.9%, aOR = 1.298, p < 0.001), smokers (15.9% vs. 10.1%, aOR = 1.198, p = 0.007), cannabis users (18.9% vs. 8.4%, aOR = 1.558, p < 0.001), or cocaine users (5.3% vs. 0.6%, aOR = 4.84, p < 0.001) showed increased odds of recording a diagnosis of AMI. Females showed lower odds than males (32.7% vs. 65%, aOR = 0.264, 95% CI: 0.24-0.291, p < 0.001). Admissions were more likely among teenagers with hypertension (9.9% vs. 2.5%, aOR = 3.382, p < 0.001). Those not covered by Medicaid or private insurances were more likely to be admitted for AMI than Medicaid beneficiaries (12.4% vs. 8.2%, aOR = 1.278, p < 0.001). Finally, teenagers classified as Blacks showed higher odds than whites of being admitted for AMI (aOR = 1.37, p < 0.001). A total of 270 (12.5%) deaths were also noted. Conclusions: Various characteristics among teenagers influence their risk for AMI. Further studies and campaigns on educating teenagers about risk factors may provide long-term benefits.

Abstract

Digital epidemiology is increasingly used for supporting traditional epidemiology. This study was hence aimed to explore whether the Google search volume may have been useful to predict the trajectory of coronavirus disease 2019 (COVID-19) outbreak in Italy.We accessed Google Trends for collecting data on weekly Google searches for the keywords "tosse" (i.e., cough), "febbre" (i.e., fever) and "dispnea" (dyspnea) in Italy, between February and May 2020. The number of new weekly cases of COVID-19 in Italy was also obtained from the website of the National Institute of Health.The peaks of Google searches for the three terms predicted by 3 weeks that of newly diagnosed COVID-19 cases. The peaks of weekly Google searches for "febbre" (fever), "tosse"( cough) and "dispnea" (dyspnea) were 1.7-, 2.2- and 7.7-fold higher compared to the week before the diagnosis of the first national case. No significant correlation was found between the number of newly diagnosed COVID-19 cases and Google search volumes of "tosse" (cough) and "febbre" (fever), whilst "dyspnea" (dyspnea) was significantly correlated (r= 0.50; p=0.034). The correlation between newly diagnosed COVID-19 cases and "tosse" (cough; r=0.65; p=0.008) or "febbre" (fever; 0.69; p=0.004) become statistically significant with a 3-week delay. All symptoms were also significantly inter-correlated. Conclusions; Continuously monitoring the volume of Google searches and mapping their origin can be a potentially valuable instrument to help predicting and identifying local recrudescence of COVID-19.

Abstract

Introduction: Very little is known about the role of atherosclerotic carotid plaque morphology, vulnerability, and Total Plaque Area (TPA) in the development of Major Cardiovascular Events (MCVE). Aim of this study: To assess the role of carotid atherosclerosis and the plaque morphology in the prediction of MCVE.\ud Importance of the study: A better understanding of the role of detection of atherosclerosis and unstable plaque morphology can help to improve strategies for prevention of Acute Cardiovascular Events (ACVE) worldwide. Methods: This study analyzed the medical records of 452 patients with 2.5-years follow-up. The primary outcomes were the composite of first occurrence of stroke, cardiovascular death, and Acute Coronary Syndromes (ACS) hospitalization.\ud Results: The results show that carotid atherosclerosis was present in 44% of patients (n=103) and this was associated with increasing conventional cardiovascular risk factors and extent of symptomatic vascular disease. During 2.5 years\ud follow-up, 10% of patients experienced ≥ 2 MCVE. After adjustment for cardiovascular risk factors, the risk of ACS and stroke increased by 23% (95% Confidence Interval [CI]), and 45% (95% confidence interval), respectively in patients with carotid ultrasonic (US) evidence of advanced carotid atherosclerosis in comparison to control (P

Abstract

Introduction: The increasing prevalence of heart failure (HF) in coronary artery disease (CAD) urgently requires the establishment of new imaging techniques for early diagnosis and also to guide treatment of patients presented with acute coronary syndromes (ACS). Conventional echocardiography (CE) and electrocardiogram (ECG) are the gold standard methods in assessing myocardial ischemia (MI) and the function of the heart in patients with coronary artery disease (CAD). The lack of ST elevation by ECG and regional wall motion abnormalities by CE in non-ST segment elevation myocardial infarction (NSTEACS) in ACS patients reflect limited sensitivity of ECG and CE in identifying patients with acute coronary occlusion (ACO) and proper assessment of myocardial viability.\ud Aim of this study: This study now evaluates the ability of strain parameters in grading the severity of CAD to detect myocardial viability in ACS through a comparative meta-analysis in two cohorts of patients living in the UAE and Qatar. The study investigates the diagnostic accuracy of left ventricular longitudinal systolic strain function (GLS) by 2D-speckle tracking echocardiography (2D-STE), Territorial Longitudinal Strain (TLS) analysis and post systolic strain (PSS) in ACS patients admitted at the emergency departments. All the patients had acute chest pain which is highly suggestive of NSTEACS along with coronary angiography (CA).\ud Methods: The study recruited two groups, comprising of 347 patients, who were presented with acute coronary syndrome (NSTEACS) at the emergency department. The first group had 214 consecutive patients who had acute chest pain and high-risk profile and they were admitted to the emergency department at Eastern Emirates Hospitals, El-Fujairah-Dibba (EEEH), UAE. The second group consisted of 133 from emergency department at Heart Hospital- Hamad Medical Corporation (HHHMC), Qatar. In both groups, 85% of the patients were men with ages from 32 to 65 years (mean ± SD: 49.4 ± 9.5 years). Significant CAD was defined as having at least one epicardial vessel with ≥ 70% or left main>50% stenosis. All patients enrolled in this study underwent basic echocardiography, speckle tracking analysis, and coronary angiography. In 70 patients, PSS was calculated and myocardial perfusion imaging (MPI) was utilized as gold standards for the assessment of myocardial viability in patients with documented NSTEACS.\ud The sensitivity, specificity, positive and negative predictive values of peak longitudinal systolic strain (2D-STE) and PSS were calculated. Left ventricular systolic strain was displayed as bull’s eye plot and territorial longitudinal strain (TLS) in the territory of the infarct-related artery. They were obtained within 24 hours from admission. Coronary angiography (CA) was performed within 24 hours from admission and used as a reference tests to assess the severity of CAD.\ud Results: Echocardiogram obtained from the patients showed any no wall motion abnormalities at rest, although speckle tracking analysis was abnormal in 167 patients. In the first group of patients from the UAE, GLS showed a high sensitivity of 80% and a very high specificity of 93% for detection of significant CAD. In addition, PSS demonstrated a high sensitivity of 80% with an average specificity of 57%. The combination of GLS and PSS showed a further increase in sensitivity, specificity with positive and negative predictive values of 98%, 91%, 99% and 97%, respectively. Therefore, a very high correlation of GLS and PSS with coronary angiography was demonstrated: =0.90, p

Abstract

Catatonia is a psychomotor syndrome characterized by numerous clinical features, a few being stupors which is the most common sign, posturing, forced grasping, echopraxia, etc. There have been cases documented in the literature of Catatonia occurring with COVID-19. This article will focus on the complete and brief overview of catatonia observed in patients with COVID-19 infection. Methods: We outline the evidence of the pathophysiology of COVID-19 in the CNS system, the effect of the virus in inducing catatonia, and its outcome. The literature used in the article is mostly case reports from different parts of the world thus; we have generalized our review taking into consideration multiple factors. Results: In patients with COVID-19, neuropsychiatric manifestations are very commonly appreciated. Catatonia has been documented in many patients along with respiratory symptoms such as fever, shortness of breath, and cough. There are multiple etiologies associated with this presentation which have been discussed in detail in this article. In many patients, there was no history of any psychiatric illness. The timing of presenting with catatonic features was also different for different individuals. Conclusion: COVID-19 has been believed to contribute to the presentation of catatonia. There is no specific timeline between the onset of symptoms and the presence of COVID-19 infection. However, coronavirus can be responsible in a few ways for inducing catatonia in patients with or without any previous psychiatric illness. Therefore, COVID-19 should be considered as one of the major factors in this complex psychiatric disease, catatonia. [ABSTRACT FROM AUTHOR]

Abstract

Introduction: COVID-19 is an ongoing pandemic that has lasted more than a year. Patients with multiple comorbidities such as diabetes, hypertension, and smoking have been shown to be at increased risk of a more severe course and lethal outcome. Since the disease can also lead to a hypercoagulable state, several cases of acute myocardial infarction (AMI) have also been recorded. Material and methods: We searched PubMed/Medline for case reports of AMI occurring in COVID-19 positive patients using "acute myocardial infarction", "COVID-19", and "SARS-CoV-2" as keywords. Results: Thirty-three articles covering 37 patients were identified, among which 30 (81.1%) were male, and 7 (18.9%) were females. The mean age of these 37 patients was 52.8 ±15.6 years. Most cases were from the United States (17 cases, 45.9%). Several comorbidities such as hypertension (16 cases, 43.2%), diabetes (14 cases, 37.8%), smoking (8 cases, 21.6%), obesity (3 cases, 8.1%), morbid obesity (1 case, 2.7%), and elevated lipid levels (4 cases, 10.8%) were also identified. The most common symptom of AMI was chest tightness (22 cases, 59.5%), while the most common symptoms for COVID-19 were dyspnoea (25 cases, 67.6%) and fever (22 cases, 59.5%). The mortality rate was 35.1%. Conclusions: Given the high mortality rate, physicians are encouraged to properly check for signs of cardiac dysfunction and possible AMI while treating COVID-19 positive patients with several comorbidities or previous history of AMI.

Abstract

Introduction: The world is currently facing the pandemic of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The total number of cases of coronavirus disease 2019 (COVID-19) is rising daily and no vaccine has yet been approved. While the pathophysiology behind the virus is still being studied, many possible several risk factors using small sample sizes have been found. Material and methods: We conducted a pooled analysis using several databases such as Medline, Scopus, Wangfang, Web of Science, Research Square, medrxiv, and Google Scholar to identify studies reporting severe and non-severe groups of COVID-19 patients. The odds ratios as well as the 95% confidence intervals for hypertension, diabetes, and cerebrovascular disease leading to severe COVID-19 were calculated using R-software. Results: Fifty-three articles were used for our analysis and they involved 30,935 confirmed cases of COVID-19 from several countries across the world. The odds ratio for severe COVID-19 in hypertensive patients, diabetics, and patients with a history of cerebrovascular disease was 2.58 (95% confidence interval (CI): 2.16-3.08, from 53 studies), 2.17 (95% CI: 1.72-2.74, from 44 studies), and 2.63 (95% CI: 1.80-3.85, from 25 studies), respectively. Conclusions: Our analysis confirms that patients with hypertension, diabetes, or cerebrovascular disease are at a higher risk of a severe outcome of COVID-19. It is thus vital for physicians to identify the main risk factors for a severe outcome of this disease. [ABSTRACT FROM AUTHOR]
