Thymus vulgaris, a natural pharmacy against COVID-19: A molecular review.

Introduction: A worldwide pandemic infection by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the cause of a deadly disease called COVID-19. Interaction of the virus and the Angiotensin converting-enzyme 2 (ACE2) receptor leads to an inflammatory-induced tissue damage. Thymus vulgaris L. (TvL) is a plant with a long history in traditional medicine that has antimicrobial, antiseptic, and antiviral properties. Thymol and Carvacrol are two important biological components in Thyme that have anti-inflammatory, antioxidant, and immunomodulatory properties. This study is a molecular review on the potential effects of TvL and its active compounds on SARS-COV2 infection. Method: This is a narrative review in which using PubMed, Scopus, ISI, Cochrane, ScienceDirect, Google scholar, and Arxiv preprint databases, the molecular mechanisms of therapeutic and protective effects of TvL and its active compounds have been discussed regarding the molecular pathogenesis in COVID-19. Results: Thyme could suppress TNF-alpha, IL-6, and other inflammatory cytokines. It also enhances the anti-inflammatory cytokines like TGF-beta and IL-10. Thyme extract acts also as an inhibitor of cytokines IL-1-beta and IL-8, at both mRNA and protein levels. Thymol may also control the progression of neuro-inflammation toward neurological disease by reducing some factors. Thyme and its active ingredients, especially Thymol and Carvacrol, have also positive effects on the renin-angiotensin system (RAS) and intestinal microbiota. Conclusions: Accordingly, TvL and its bioactive components may prevent COVID-19 complications and has a potential protective role against the deleterious consequences of the disease.

A Review of Long COVID With a Special Focus on Its Cardiovascular Manifestations.

The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus has been the cause of the century's worst pandemic so far: coronavirus disease 2019 (COVID-19). It has led to unprecedented mortality and morbidity, resulting in devastating consequences worldwide. The acute manifestations of COVID-19 including respiratory as well as multisystem involvement have been causes of great concern among physicians. However, the long-term effects of the coronavirus have left many patients battling with chronic symptoms, ranging from extreme fatigue to cardiomyopathy. In this article, we review the chronic manifestations of COVID-19 with a focus on cardiovascular manifestations. We discuss the pathophysiology, post-acute sequelae, clinical manifestations, approach to the laboratory diagnosis of cardiovascular manifestations of long COVID, and a proposed multidisciplinary treatment method. We also explore the relationship between vaccination and the long COVID syndrome.

T-wave Inversions in Cerebellar and Occipital Lobe Infarcts in the Setting of Deep Vein Thrombosis and Pulmonary Embolism Suggestive of Paradoxical Emboli: A Case Report

Cardiological causes account for the majority of acute electrocardiographic (ECG) changes. The reason for this fear is the irreversibility of myocardial necrosis. Generally, various changes can be observed in the ECG, including ST-T changes, QTc prolongation, arrhythmias, and T-wave inversions. Even though T-wave inversions can be seen in myocardial ischemia/infarction, they are rarely seen in acute cerebrovascular accidents (CVAs). We present the case of a 66-year-old woman who initially presented at our facility with dizziness in the context of orthostatic hypotension. An initial cardiac evaluation revealed no cardiac involvement. She was treated with intravenous fluids (IVF), which improved her symptoms. The patient's mental status was markedly altered approximately four days after admission. In this instance, she was found to have abnormal ECG findings (not previously observed on the ECG that was obtained on the day of admission), elevated troponin T levels, as well as elevated pro-B-type natriuretic peptide (pro-BNP). The patient was given aspirin and clopidogrel immediately and was placed on a heparin drip for a suspected non-ST elevation myocardial infarction (NSTEMI). A non-contrast computed tomography of the head revealed an acute cerebrovascular accident (CVA), following which the heparin drip was stopped. The patient was then transferred to another acute care facility capable of performing neurosurgical interventions. Additionally, a computed tomography angiography (CTA) of the chest and lower extremities venous duplex showed bilateral pulmonary emboli and deep venous thrombosis (DVT), respectively.

Diabetes, Heart Failure, and COVID-19: An Update.

The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was declared a pandemic by the WHO in March 2020. As of August 2021, more than 220 countries have been affected, accounting for 211,844,613 confirmed cases and 4,432,802 deaths worldwide. A new delta variant wave is sweeping through the globe. While previous reports consistently have demonstrated worse prognoses for patients with existing cardiovascular disease than for those without, new studies are showing a possible link between SARS-CoV-2 infection and an increased incidence of new-onset heart disease and diabetes, regardless of disease severity. If this trend is true, with hundreds of millions infected, the disease burden could portend a potentially troubling increase in heart disease and diabetes in the future. Focusing on heart failure in this review, we discuss the current data at the intersection of COVID, heart failure, and diabetes, from clinical findings to potential mechanisms of how SARS-CoV-2 infection could increase the incidence of those pathologies. Additionally, we posit questions for future research areas regarding the significance for patient care.

Ventricular Septal Defect in Delayed Presentation of ST-Elevation Myocardial Infarction (STEMI) Secondary to COVID-19 Pandemic.

Like many other countries at the moment, the United Kingdom (UK) is currently under national lockdown due to the coronavirus disease 2019 (COVID-19) pandemic. An unfortunate consequence of such social isolation measures is that patients with genuine acute medical emergencies may not present to a hospital in a timely manner. We present such a scenario, whereby a patient had a delayed presentation of ST-elevation myocardial infarction (STEMI) due to fear of breaching COVID-19 lockdown rules. As a result of the patient presenting well outside the optimal treatment window, her STEMI was complicated by a severe ventricular septal defect (VSD). We discuss how the COVID-19 pandemic has influenced the nature and management of STEMIs and associated issues.

Early-Onset Type 2 Diabetes Mellitus.

Globally, the prevalence of chronic, non-communicable diseases is increasing at an alarming rate. Amongst it, Type 2 diabetes mellitus (DM) is becoming more prevalent among young individuals due to obesity and sedentary habits. With the advent of COVID-19, there has been an increasing trend for diabetes and its complications. Here we describe a 13-year-old female girl with polyuria, polydipsia for two months with further assessment leading to a diagnosis of Type 2 DM who is now closely monitored by a pediatric endocrinologist. She remains euglycemic with insulin and lifestyle changes. Early-onset DM is complex and requires multidisciplinary care for preventing complications and comorbidities. Hence, early recognition and management are crucial.
