COPD as an additional risk factor for cardiovascular and respiratory events in patients with respiratory viral infection

Introduction: Patients with chronic obstructive pulmonary disease (COPD) have higher risk of hospitalization for cardiovascular events (CVE). An association between influenza infection and myocardial infarction (MI) is established. Our objective is to evaluate the COPD as an additional risk factor for CVE and respiratory events (RE) in patients with respiratory viral infection.Methods: We performed a retrospective cross-sectional analysis of 139 patients, with positive PCR for respiratory viruses in January of 2018. Cardiovascular risk factors (CVRF) (hypertension, diabetes, dyslipidemia and smoking) and medical history were registered. CVE (MI, stroke and heart failure) and RE (pneumonia, acute bronchitis, asthma or COPD exacerbations) were collected during the following year after a positive respiratory virus.Results: 52.5% of the patients were women. The most frequent viruses were influenza A (20.9%) and B (30.9%). 33.8% had lung diseases (20.1%, COPD) and 67.6% had CVRF. 12 patients developed a CVE (8.6%); 5 with pulmonary disease (2 with COPD and 4 with CVRF) and 7 without lung disease and with CVRF. There was no statistical significance between these associations. Only patients with CVRF without COPD and women with CVRF had more CVD (p

CONCLUSIONS: Elevated plasma TMAO level in patients with heart failure is associated with poorer prognoses. This association is only partially mediated by renal dysfunction. PMID: 32959366 [PubMed - as supplied by publisher]

Getting the right care in a timely manner is important in medical emergencies. In the event that you or a loved one suffers a stroke, time is especially critical. “In the event of a stroke, a delay of only 15 minutes in treatment greatly decreases your chances not only of making a full recovery, but also being able to walk or live independently, and in many cases, of survival,” says Christopher Zammit, MD, a critical care specialist and emergency physic ian with TriHealth, which offers a network…

Abstract The optic nerve sheath (ONS) is biomechanically important. It is acted on by tension due to ocular movements, and by fluid shifts and/or alterations in intracranial pressure (ICP) in human disease, specifically in pathologies leading to intracranial hypertension. It has also been hypothesized that the ONS is acted on by altered ICP in astronauts exposed chronically to microgravity. However, a non-invasive method to quantify ONS biomechanical properties is not presently available; knowledge of such properties is desirable to allow characterization of the biomechanical forces exerted on the optic nerve head...

Authors: Zhang Y, Liu Y, Zhu J, Zhai S, Jin R, Wen C Abstract The Traditional Chinese Medicine (TCM) formula is the main treatment method of TCM. A formula often contains multiple herbs where core herbs play a critical therapeutic effect for treating diseases. It is of great significance to find out the core herbs in formulae for providing evidences and references for the clinical application of Chinese herbs and formulae. In this paper, we propose a core herb discovery model CHDSC based on semantic analysis and community detection to discover the core herbs for treating a certain disease from large-scale literatur...

We describe a patient suffering from bilateral intracerebral hemorrhage after severe olanzapine intoxication without underlying thrombocytopenia, arterial hypertension, or vascular malformation as cause of intracerebral hemorrhage. This raises the possibility of a direct side effect of high-dose olanzapine intake. So far, intracranial hemorrhage after olanzapine intoxication in such constellation has not been reported before. Given the high number of its prescription rates, our finding of intracranial hemorrhage after olanzapine intoxication is of high clinical relevance. PMID: 32953191 [PubMed]
