As of June 2020, the virus had spread across 216 countries across the globe. This paper aims to analyze and identify those existing comorbidities among COVID‑19 patients that represent potential risk factors for COVID‑19 complications, severe illness, and death. Multiple database resources were searched. The resources include the University of Saskatchewan library USearch, Google Scholar, PubMed, Medline, and the Google search engine. Thirty‑seven articles, which included 15 different types of chronic diseases, were selected. Among the reviewed diseases and conditions, cancer, diabetes, lymphopenia, hypertension, kidney disease, smoking, chronic obstructive pulmonary disease (COPD), and organ transplant were found to represent potential risk factors for COVID‑19 complications, severe illness, and death. Other conditions that require further research as to whether they predispose subjects to severe illness and death include coronary artery disease, cerebrovascular disease, valvular heart disease, gastrointestinal diseases, HIV/AIDS, asthma, and liver disease. In conclusion, this article explains the association between diseases mentioned above and the severity of COVID‑19 and clearly shows the population at risk. This paper will help government bodies and decision‑makers prioritize resources for these populations to reduce mortality rates and overall quality of life.http://ijpm.mui.ac.ir/index.php/ijpm/article/view/2702http://ijpm.mui.ac.ir/index.php/ijpm/article/download/2702/717718543

The virus poses a great threat to global health and the economy. Currently, in the absence of effective treatment or vaccine, leveraging advanced digital technologies is of great importance. In this respect, the Internet of Things (IoT) is useful for smart monitoring and tracing of COVID‑19. Therefore, in this study, we have reviewed the literature available on the IoT‑enabled solutions to tackle the current COVID‑19 outbreak. <strong>Methods</strong>: This systematic literature review was conducted using an electronic search of articles in the PubMed, Google Scholar, ProQuest, Scopus, Science Direct, and Web of Science databases to formulate a complete view of the IoT‑enabled solutions to monitoring and tracing of COVID‑19 according to the FITT (Fit between Individual, Task, and Technology) model. <strong>Results</strong>: In the literature review, 28 articles were identified as eligible for analysis. This review provides an overview of technological adoption of IoT in COVID‑19 to identify significant users, either primary or secondary, required technologies including technical platform, exchange, processing, storage and added‑value technologies, and system tasks or applications at “on‑body,” “in‑clinic/hospital,” and even “in‑community” levels. <strong>Conclusions</strong>: The use of IoT along with advanced intelligence and computing technologies for ubiquitous monitoring and tracking of patients in quarantine has made it a critical aspect in fighting the spread of the current COVID‑19 and even future pandemics.http://ijpm.mui.ac.ir/index.php/ijpm/article/view/2705http://ijpm.mui.ac.ir/index.php/ijpm/article/download/2705/717718546

Therefore, the current study evaluated the level of FC and its diagnostic value in patients with H. Pylori and its related conditions including gastritis and duodenitis.</p><p><strong>Methods</strong>: In this case‑control study, 120 children with upper GI symptoms, who were indicated to undergo upper GI endoscopic examination, were consecutively included. Patients were categorized into different groups based on their endoscopic findings including H. pylori, gastritis, duodenitis or normal.</p><p><strong>Results</strong>: Patients with gastritis (P = 0.014) and those with duodenitis (P &lt; 001) had significantly higher FC. The level of FC was higher in patients with H. pylori but this difference was marginally significant (P = 0.054). The level of FC had poor ability to diagnose the presence of H. pylori (P = 0.054) and gastritis (area under the curve, AUC = 0.639, P = 0.014). However, it had acceptable power to diagnose patients with or duodenitis (AUC = 0.718, P &lt; 0.001). The sensitivity and specificity of FC for diagnosis of gastritis were 64 and 65 percent (cut‑off = 45.2 µg/g), and for duodenitis were 77 and 61 percent (cut‑off = 46.2 µg/g), respectively.</p><p><strong>Conclusions</strong>: FC can be considered as an objective and diagnostic tool for duodenitis. However, due to the low sensitivity and specificity, it is suggested to consider it as an objective supplementary test beside other established diagnostic modalities.</p>http://ijpm.mui.ac.ir/index.php/ijpm/article/view/2700http://ijpm.mui.ac.ir/index.php/ijpm/article/download/2700/717718541

The main objective of the study was to assess the incidence of COVID‑19 infection and identify the source of infection among the HCWs in a tertiary teaching hospital.</p><p><strong>Methods</strong>: A prospective cohort study was conducted among the 2134 HCWs recruited by purposive sampling from a tertiary teaching hospital from May to August 2020 (4‑month period—123 days). Over the 4‑month period, all the HCWs who had symptoms or those were close contacts of COVID positive patients were traced and tested using validated COVID diagnostic test (reverse transcription–polymerase chain reaction [RT–PCR] test). A semi‑structured questionnaire was used to interview each positive HCW to identify the source of exposure of the infection.</p><p><strong>Results</strong>: Incidence proportion was 9.3% among HCWs and was two times higher among males compared to females. Hazard ratio was found to be higher among males and HCWs working in the non‑COVID areas. Test positivity rate was found to highest (around 57.8%) among those aged less than 30 years. The most common source of infection was infected HCW colleagues (40.9%) followed by exposure to patients in non‑COVID areas (27.3%). Only 5.1% of total infection was found in HCWs who had worked in COVID zones.</p><p><strong>Conclusions</strong>: People working in non‑COVID areas, those using shared workplace, dining halls, and staff hostels, must follow strict COVID protocols by using appropriate Personal Protective Equipment (PPE) and following social distancing measures.</p>http://ijpm.mui.ac.ir/index.php/ijpm/article/view/2701http://ijpm.mui.ac.ir/index.php/ijpm/article/download/2701/717718542

Understanding knowledge, attitudes, and practices (KAP) of the public towards the pandemic is an essential part of developing effective preventive strategies. <strong>Aim</strong>: The objective of this study was to investigate the knowledge, attitudes, and practices (KAP) concerning the coronavirus (COVID‑19) among population in Istanbul. <strong>Methods</strong>: This is a cross‑sectional and multi‑stage, stratified random sampling based on multi‑center population of Istanbul. A total of 5,414 persons were contacted and 4361 participants (80.5%) gave consent. The data were analyzed using descriptive and multiple regression analyses. <strong>Results</strong>: There were significant differences between low education and high educational level with respect to age groups, gender, occupation, income, residence, number of rooms and family members (P &lt; 0.001). Responses concerning knowledge of COVID‑19 indicated that subjects with high education level were significantly higher regarding knowledge of the signs and symptoms of COVID‑19 and methods of detecting COVID‑19 respectively. Majority of the participants consider COVID‑19 risk is higher than AIDS or Cancer (75.8% of low education vs. 67.2% of high education level (P &lt; 0.001). Multivariate stepwise regression analysis revealed that monthly income status (P &lt; 0.001), appropriate method of detecting COVID‑19 (P &lt; 0.001), occupational status (P &lt; 0.001), medical mask prevent against COVID‑19 (P &lt; 0.001), eating or contacting wild animals (P &lt; 0.001), isolation and treatment of people reduce risk (P &lt; 0.001), isolation 14 days (P &lt; 0.001), avoid going to crowded places such as train‑metro, bus, restaurants and shopping (P = 0.003), COVID‑19 spreads via‑respiratory droplets (P = 0.004), afraid of travel (P = 0.026) were significantly associated with COVID‑19 knowledge. <strong>Conclusions</strong>: The current study results revealed that the educational level and occupation especially sedentary are correlated positively with knowledge, attitude and practices. This finding is not surprising since higher education levels and professional status are associated with good KAP in most epidemic diseases including COVID‑19. Nevertheless, the recent experience with COVID‑19 has provided lessons on strategy and policy making.http://ijpm.mui.ac.ir/index.php/ijpm/article/view/2704http://ijpm.mui.ac.ir/index.php/ijpm/article/download/2704/717718545
