Internet forums are an attractive source of health-related information. We aimed to investigate threads in the gastroenterological section of a popular Polish medical forum for anonymous users. We characterised the following aspects in threads: the main problem of the original poster, declared ailments and rationale of the responses (rational, neutral, harmful or not related to the problem of the original poster). We analysed over 2717 forum threads initiated in the years 2010–2018. Users mostly asked for diagnosis of the problem [1814 (66.8%)], treatment [1056 (38.9%)] and diagnostic interpretation [308 (11.3%)]. The most commonly declared symptoms were abdominal pain [1046 (38.5%)], diarrhea [454 (16.7%)] and bloating [354 (13.0%)]. Alarm symptoms were mentioned in 309 (11.4%) threads. From the total 3550 responses, 1257 (35.4%) were assessed as rational, 693 (19.5%) as neutral, 157 (4.4%) as harmful and 1440 (40.6%) as not related to the user’s problem. The original poster’s declaration of blood in stool, dyspepsia, pain in the abdominal right lower quadrant, weight loss or inflammatory bowel disease was positively related to obtaining at least one potentially harmful response. Advice from anonymous users on Internet forums may be irrational and disregards alarm symptoms, which can delay the diagnosis of life-threatening diseases.
Introduction: Inflammation and angiogenesis disturbances are considered as factors contributing to the development of coronary artery ectasias (CAE). Endocan (endothelial cell-specific molecule-1-ESM-1) regulates both inflammatory and angiogenetic processes. However, there are no data about the correlation between endocan level and the severity of CAE measured with total volume of coronary artery dilation. Aim: To assess whether the severity of the inflammatory process measured as endocan concentration correlates with the total volume of CAE. Material and methods: We selected prospectively a total of 43 consecutive patients with coronary artery ectasia from 2240 patients who underwent coronary angiography in our center. Determination of endocan was performed by using the Human Endothelial cell-specific Molecule 1 (ECSM1/ENDOCAN) ELISA Kit. 3D QCA (three-dimensional quantitative coronary angiography) was used for coronary lesion and aneurysm quantification. The total volume of dilation was defined as the volume of all aneurysms and ectasias of coronary arteries in 1 patient. Results: The mean volume of all aneurysms in 1 patient was 677 ±878.7 mm 3. The total aneurysm volume was positively strongly correlated with endocan concentration (Pearson correlation coefficient: 0.811; 2-tailed p < 0.001). Conclusions: Endocan is a potential marker of vascular wall damage mainly as a result of inflammation in the course of atherosclerosis, but also vascular remodeling as a result of a disturbance of pro-and anti-angiogenic processes. Endocan level reflects the intensity of the above processes and therefore correlates with the severity of CAE, measured as the total volume of dilation.
The Internet enables immediate access to health-related information. We aimed to rank the complaints related to cardiovascular diseases among Google users globally and locally as well as investigate secular and seasonal trends in the years 2004 to 2019. We used Google Trends (GT) to identify and analyze course over time and regional interest of seven topics: “Chest pain,” “Cyanosis,” “Edema,” “Orthopnea,” “Palpitation,” “Shortness of breath,” and “Syncope.” We analyzed secular trends using the seasonal Mann–Kendall test and seasonal variation using time series decomposition. We calculated the interest of all topics in proportion to the relative search volume (RSV) of “Chest Pain.” Globally the most popular topics were: “Edema” (proportion to RSV of “Chest pain,” 1.39), “Chest pain” (1.00), and Syncope (0.71). “Chest pain” was predominately searched in n = 25 countries, while “Edema” in n = 24, “Syncope” in n = 9, and “Shortness of breath” in n = 3. The RSV of all topics increases over time and the most dynamically for “Chest pain” (4.30 RSV/year), “Shortness of breath” (3.87 RSV/year), and “Palpitations” (3.69 RSV/year). Interest in “Chest pain,” “Cyanosis,” “Orthopnea,” “Palpitations,” and “Syncope” peaks in fall and winter, while interest in “Edema” in midsummer and “Shortness of breath” in April. Google users were particularly interested in “Edema,” “Chest pain,” and “Syncope.” The interest in cardiovascular diseases-related symptoms increases over time and presents explicable seasonal variations. The Internet plays the acquisition of health-related information; thus, professionals should create and recommend evidence-based information sources for their patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
