Evaluation of the Expression of Infection-Related Long Noncoding RNAs among COVID-19 Patients: A Case-Control Study.

Background and Aims: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a worldwide pandemic, activates signaling cascades and leads to innate immune responses and secretion of multiple chemokines and cytokines. Long noncoding RNAs (lncRNAs) have a crucial role in inflammatory pathways. Through our search on the PubMed database, we discovered that existing research has primarily focused on examining the regulatory impacts of five lncRNAs in the context of viral infections. However, their role in regulating other conditions, including SARS-CoV-2, has not been explored. Therefore, this study aimed to investigate the expression pattern of lncRNAs in the peripheral blood mononuclear cells (PBMC) and their potential roles in SARS-CoV-2 infection. Potentially significant competing endogenous RNA (ceRNA) networks of these five lncRNAs were found using online in-silico techniques. Methods: Ethylenediaminetetraacetic acid (EDTA) blood samples of the control group consisted of 45 healthy people, and a total of 53 COVID-19-infected patients in case group, with a written informed consent, was collected. PBMCs were extracted, and then, the RNA extraction and complementary DNA (cDNA) synthesis was performed. The expression of five lncRNAs (lnc ISR, lnc ATV, lnc PAAN, lnc SG20, and lnc HEAL) was assessed by real-time PCR. In order to evaluate the biomarker roles of genes, receiver operating characteristic (ROC) curve was drawn. Results: Twenty-four (53.3%) and 29 (54.7%) of healthy and COVID-19-infected participants were male, respectively. The most prevalent symptoms were as follows: cough, general weakness, contusion, headache, and sore throat. The results showed that three lncRNAs, including lnc ISR, lnc ATV, and lnc HEAL, were expressed dramatically higher in the case group compared to healthy controls. According to ROC curve analysis, lnc ATV has a higher AUC and is a better biomarker to differentiate COVID-19 patients from the healthy controls. Then, using bioinformatics methods, the ceRNA network of these lncRNAs enabled the identification of mRNAs and miRNAs with crucial functions in COVID-19. Conclusion: The considerable higher expression of ISR, ATV, and HEAL lncRNAs and the significant area under curve (AUC) in ROC curve demonstrate that these RNAs probably have a potential role in controlling the host innate immune responses and regulate the viral replication of SARS-CoV-2. However, these assumptions need further in vitro and in vivo investigations to be confirmed.

Upregulation of hsa_circ_0004812 promotes COVID-19 cytokine storm via hsa-miR-1287-5p/IL6R, RIG-I axis.

BACKGROUND: SARS-CoV-2 is one of the most contagious viruses in the Coronaviridae (CoV) family, which has become a pandemic. The aim of this study is to understand more about the role of hsa_circ_0004812 in the SARS-CoV-2 related cytokine storm and its associated molecular mechanisms. MATERIALS AND METHODS: cDNA synthesis was performed after total RNA was extracted from the peripheral blood mononuclear cells (PBMC) of 46 patients with symptomatic COVID-19, 46 patients with asymptomatic COVID-19, and 46 healthy controls. The expression levels of hsa_circ_0004812, hsa-miR-1287-5p, IL6R, and RIG-I were determined using qRT-PCR, and the potential interaction between these molecules was confirmed by bioinformatics tools and correlation analysis. RESULTS: hsa_circ_0004812, IL6R, and RIG-I are expressed higher in the severe symptom group compared with the negative control group. Also, the relative expression of these genes in the asymptomatic group is lower than in the severe symptom group. The expression level of hsa-miR-1287-5p was positively correlated with symptoms in patients. The results of the bioinformatics analysis predicted the sponging effect of hsa_circ_0004812 as a competing endogenous RNA on hsa-miR-1287-5p. Moreover, there was a significant positive correlation between hsa_circ_0004812, RIG-I, and IL-6R expressions, and also a negative expression correlation between hsa_circ_0004812 and hsa-miR-1287-5p and between hsa-miR-1287-5p, RIG-I, and IL-6R. CONCLUSION: The results of this in-vitro and in silico study show that hsa_circ_0004812/hsa-miR-1287-5p/IL6R, RIG-I can play an important role in the outcome of COVID-19.

The Effect of Educational Intervention Based on PRECEDE Model on Health Promotion Behaviors, Hope Enhancement, and Mental Health in Cancer Patients.

In this experimental study, 200 cancer patients (100 subject in experimental group and 100 subjects in control group) referred to Amir Oncology Hospital in Shiraz were investigated. Educational intervention for experimental group consisted of 12 educational sessions for 50 to 55 minutes. A questionnaire including demographic information, PRECEDE constructs (knowledge, attitude, self-efficacy, enabling factors, and social support), was used to measure health promotion behaviors, patients' hope, and mental health before and 6 months after intervention. Six months after intervention, experimental group showed significant increase in knowledge, attitude, self-efficacy, enabling factors, social supports, health promotion behaviors, patients' hope, and mental health compared to the control group. This study showed the effectiveness of intervention based on PRECEDE constructs in mentioned factors 6 months after intervention. Hence, this model can act as a framework for designing and implementing educational intervention for health promotion behaviors of cancer patients.

BACKGROUND: The nurses act as the guardians of people's health by preventing, controlling, and curing emerging diseases, including coronavirus, a highly infectious and contagious disease which has presented the caregivers in the Iranian healthcare system with many clinical challenges. In view of lack of research on the clinical challenges which arise during health crises, emerging diseases included, there is need for further investigation of those clinical challenges and dilemmas. The aim in present study was to describe the caregivers' experiences of the caring challenges in patients with coronavirus (COVID-19). METHODS: The present study is a qualitative work with a phenomenological-descriptive design. Data were collected via semi-structured, in-depth, individual interviews. The collected data were analyzed according to Colaizzi's method. The participants were 23 members of the medical staff responsible for coronavirus patients in Iran who met the inclusion criteria. The participants were selected via purposeful sampling which was continued to the point of data saturation. RESULTS: The results yielded 3 main themes "psychological tension", "inefficient management", and "contextual factors" with 11 categories. CONCLUSION: In dealing with coronavirus patients and providing quality care to them, nurses face various clinical challenges which affect their performance. Administrators must, alongside giving instructions to people on how to prevent the coronavirus disease and taking effective safety measures, make sure that clinical centers are managed efficiently in order for nurses to fulfill their caring objectives satisfactorily.

The use of mobile health interventions for gestational diabetes mellitus: a descriptive literature review.

This study attempted to review the evidence for or against the effectiveness of mobile health (m-health) interventions on health outcomes improvement and/or gestational diabetes mellitus (GDM) management. PubMed, Web of Science, Scopus, and Embase databases were searched from 2000 to 10 July 2018 to find studies investigating the effect of m-health on GDM management. After removing duplications, a total of 27 articles met our defined inclusion criteria. m-health interventions were implemented by smartphone, without referring to its type, in 26% (7/27) of selected studies, short message service (SMS) in 14.9% (4/27), mobile-based applications in 33.3% (9/27), telemedicine-based on smartphones in 18.5% (5/27), and SMS reminder system in 7.1% (2/27). Most of the included studies (n=23) supported the effectiveness of m-health interventions on GDM management and 14.3% (n=4) reported no association between m-health interventions and pregnancy outcomes. Based on our findings, m-health interventions could enhance GDM patients' pregnancy outcomes. A majority of the included studies suggested positive outcomes. M-health can be one of the most prominent technologies for the management of GDM.

Health Professionals' Perception of Psychological Safety in Patients with Coronavirus (COVID-19).

BACKGROUND: Medical personnel act as the protectors of people's health by preventing, controlling, and treating emerging diseases, including the coronavirus infection. COVID-19 is a highly infectious and contagious disease which has presented the Iranian healthcare system with a variety of clinical challenges. There is a lack of research on clinical challenges in health crises especially those caused by emerging diseases, hence a need for more exploration of these clinical challenges and dilemmas. The present study aims to determine the different aspects of health professionals' perception of the psychological safety of patients infected with the coronavirus (COVID-19). METHODS: The present study is a qualitative work which uses conventional content analysis. The participants were 17 health professionals who were responsible for COVID-19 patients and met the inclusion criteria. They were selected via purposeful sampling. The study lasted from February to March 2020. Data were collected through semi-structured, individual interviews which were conducted via video call. The collection of data was kept up to the point of saturation. The collected data were analyzed using the conventional content analysis method. RESULTS: Three themes such as "respect for dignity", "comprehensive support" and "peaceful environment" with 11 categories were extracted from the findings of the study. CONCLUSION: According to the results of the present study, patients infected with the coronavirus should be given care in a peaceful environment where they receive comprehensive support and have their dignity respected. Such conditions can guarantee the psychological safety of these patients and produce positive behavioral results on their part. Thus, it is essential that the cultural, professional, and organizational prerequisites of protecting all the dimensions of the psychological safety of these patients be provided.

Challenges of Iranian Clinicians in Dealing with COVID-19: Taking Advantages of The Experiences in Wenzhou.

The novel coronavirus has been spreading since December 2019. It was initially reported in Wuhan, Hubei province of China. Coronavirus disease 2019 (COVID-19) has currently become a pandemic affecting over seven million people worldwide, and the number is still rising. Wenzhou, as the first hit city out of Hubei Province, achieved a remarkable success in effectively containing the disease. A great record was also observed in Wenzhou for the clinical management of COVID-19 patients, leading to one of the lowest death rates in China. Researchers and clinical specialists proposed and formulated combined approaches such as computerized tomography (CT)- scans and molecular assays, as well as using both allopathic and traditional medications to mitigate its effects. Iranian and Chinese specialists and scientists had a communication in clinical, molecular and pharmaceutical aspects of COVID-19. A proper guideline was prepared according to the experiences of Chinese clinicians in managing the full spectrum of COVID-19 patients, from relatively mild to highly complex cases. The purpose of this guideline is to serve a reference in the hospital for specialists so that they may better diagnose cases and provide effective therapies and proposed antiviral and anti-inflammatory drugs for patients.

In vitro activity of four triazole antifungal drugs against clinically common and uncommon yeast species.

BACKGROUND AND PURPOSE: Incidence of fungal infections caused by opportunistic fungal pathogens, such as yeasts and yeast-like species, has undergone an increase in otherwise healthy individuals. These pathogens account for high mortality and show reduced susceptibility to the routine antifungal drugs. Accordingly, antifungal susceptibility testing is an urgent need in the determination of the susceptibility spectrum of antifungals and selection of appropriate antifungal agents for the management of patients with fungal infection. MATERIALS AND METHODS: The present study was conducted on 110 yeast strains belonging to 15 species recovered from clinical specimens. Susceptibility of the isolates to four antifungal drugs (i.e., fluconazole, itraconazole, voriconazole, and posaconazole) was tested according to the Clinical and Laboratory Standards Institute guidelines M27-A3 and M27-S4. RESULTS: Fluconazole exhibited no activity against 4.3% (n=2) of C. albicans isolates, whereas the remaining 44 isolates had a minimum inhibitory concentration (MIC) range of 0.125-4 µg/ml. Voriconazole had the lowest geometric mean MIC (0.03 µg/ml) against all isolated yeast species, followed by posaconazole (0.07 µg/ml), itraconazole (0.10 µg/ml), and fluconazole (0.60 µg/ml). Overall, all of the isolates had reduced voriconazole MICs with a MIC range of 0.016-0.5 µg/ml, except for one isolate of C. albicans that had a MIC of 1 µg/ml. Candida haemulonii as a multidrug-resistant fungus showed a fluconazole MIC of > 64 µg/ml. CONCLUSION: The current study provides insight into the antifungal susceptibility profiles of clinically common and uncommon yeast species to four triazole antifungal agents. According to our findings, voriconazole was the most active agent. Awareness about antifungal susceptibility patterns is highly helpful in the selection of appropriate antifungal drugs and identification of the efficiency of the currently used agents.

The Effect of Educational Intervention Based on Health Belief Model and Social Support on the Rate of Participation of Individuals in Performing Fecal Occult Blood Test for Colorectal Cancer Screening

Background and Aim: Among the screening tests for colorectal cancer, fecal occult blood test (FOBT) is important in comparison other methods due to its ease of use and low cost.The aim of this study is to survey the effect of educational intervention based on health belief model and social support on the rate of participation of individuals in performing fecal occult blood test for colorectal cancer screening among men who referred to the health centers in FasaCity, Fars province, Iran. Materials and Methods: In this quasi-experimental study, 200 men (100 in experimental group and 100 in control group) in FasaCity, Fars province, Iranwere selected in 2017. A questionnaire consisting of demographic information, knowledge, HBM constructs (perceived susceptibility, severity, benefits, barriers, self- efficacy and cues to action) and social support was used to measure the rate of participation of individuals in performing Fecal Occult Blood Test for colorectal cancer screening before and three months after the intervention. Data were analyzed using SPSS22 viadescriptive and inferential statistics, paired t-test, Mann-Whitney, Chi-square, and independent t-test at a significance level of 0.5. Results: The mean age of the men was 63.18 ± 8.25 years in the experimental group and 65.11 ± 7.66 years in the control group. Three months after the intervention, the experimental group showed a significant increase in the knowledge, perceived susceptibility, perceived severity, perceived benefits, Self-efficacy, cues to action, social support and the level of referrals (participation) of subjects for FOBTcompared to the control group. Conclusion: This study showed the effectiveness of HBM constructs and social support in adoption of the level of participation of subjects for FOBTin men. Hence, these models can act as a framework for designing and implementing educational interventions for undergoing FOBT.
