Comparison of atherosclerotic cardiovascular disease (ASCVD) and Framingham risk scores (FRS) in an Iranian population.

Background: Framingham risk score (FRS) and Atherosclerotic Cardiovascular Disease risk score (ASCVDrs) are widely used tools developed based on the American population. This study aimed to compare the ASCVDrs and FRS in an Iranian population. Method: The participants of the Fasa Adult Cohort Study and the patients of the cardiovascular database of Vali-Asr Hospital of Fasa, aged 40-80 years, were involved in the present cross-sectional study. After excluding non-eligible participants, the individuals with a history of myocardial infarction or admission to the cardiology ward due to heart failure were considered high-risk, and the others were considered low-risk. The discriminative ability of FRS and ASCVDrs was evaluated and compared using receiver operating characteristic curve analysis. The correlation and agreement of ASCVDrs and FRS were tested using Cohen Kappa and Spearman. Results: Finally, 8983 individuals (mean age:53.9 ± 9.5 y, 49.2 % male), including 1827 high-risk participants, entered the study. ASCVDrs detected a greater portion of participants as high-risk in comparison with FRS (28.7 % vs. 15.7 %). ASVD (AUC:0.794) had a higher discriminative ability than FRS (AUC:0.746), and both showed better discrimination in women. Optimal cut-off points for both ASCVDrs (4.36 %) and FRS (9.05 %) were lower than the original ones and in men. Compared to FRS, ASCVDrs had a higher sensitivity (79.3 % vs. 71.6 %) and lower specificity (64.5 % vs. 65.1 %). FRS and ASCVDrs had a moderate agreement (kappa:0.593,p-value<0.001) and were significantly correlated (Spearman:0.772,p-value<0.001). Conclusions: ASCVDrs had a more accurate prediction of cardiovascular events and identified a larger number of people as high-risk in the Iranian population.

The relationship between moral courage, team work, and safe nursing care in clinical nurses: a multicenter cross-sectional study in Iran.

BACKGROUND: Moral courage and team work are the most important aspects of professional competence in clinical nurses; nurses with moral courage and team work are thought to be able to deliver safe nursing care to patients. The present study aimed to investigate whether moral courage and teamwork correlate with safe nursing care among clinical nurses. METHODS: This descriptive cross-sectional multicenter study was carried out from December 2023 to February 2024. A total of 375 nurses who were practicing in four hospitals in the south of Iran were enrolled in this study using convenience sampling. The data collection tools used consisted of a demographics survey, Moral Courage Questionnaire (MCQ), Team STEPPS Team Perception Questionnaire (T-TPQ), and the Assessment of Safe Nursing Care Questionnaire (ASNCQ). The data were analyzed using descriptive statistics, t-test, chi-square, multiple regression analysis, and Pearson's correlation coefficient. SPSS version 22 was used to analyze the data. RESULTS: The participants' mean age was 32.66 ± 6.63 years, and their work experience was 8.56 ± 6.22 years. The total mean scores for moral courage, teamwork, and safe care were 422.37 ± 52.92, 144.09 ± 18.43, 315.84 ± 41.95, respectively. A statistically significant positive correlation was found between teamwork and safe care (r = 0.57, p < 0.001), teamwork and moral courage (r = 0.49, p = 0.002), and moral courage and safe nursing care (r = 0.59 p < 0.001). According to the results, work experience, moral courage, and teamwork explained 44.4% of the variance in safe nursing care (R2 = 0.44, p < 0.001). CONCLUSION: The results indicated that the moral courage and teamwork of nurses were positively and significantly correlated with the participants' safe nursing care. Accordingly, since moral courage and teamwork are the qualities that can contribute to improving the quality of care and ensuring safe nursing care, it is recommended that nursing managers pay special attention to these factors.

Online exercise added to ergonomic advice for reducing habitual upper body postures: A randomized trial.

BACKGROUND: Online learning during the COVID-19 pandemic is associated with unfavorable habitual upper body postures. OBJECTIVE: This study explored whether adding a remedial exercise routine to an ergonomic advice intervention, delivered remotely, is helpful for reducing habitual postures of the neck, shoulders, and upper back. DESIGN: Pragmatic randomized controlled trial. METHODS: 42 male adolescent students, initially selected with a forward head posture, were randomized to one of two intervention groups: ergonomic advice alone or exercise + ergonomic advice. Outcome measures were specific postural angles of, measured by a photogrammetric profile technique using a bespoke app before and after the 8-week intervention period. RESULTS: During online learning, most students used mobile phones (76%), while 35% used a table-chair-computer arrangement. At 8-week follow-up, a statistically significant reduction of forward head, shoulder protraction, and thoracic kyphosis angles was found in both groups (P < 0.001). However, the effect was significantly greater in the exercise + ergonomic advice group (P < 0.001): forward head, shoulder protraction, and thoracic kyphosis angles reduced by some 9, 6, and 5° respectively, compared with 4° for head and 2° for shoulder and thoracic angles for the ergonomic advice alone group. CONCLUSION: The results show that, a remedial online exercise routine is a beneficial addition to an ergonomic advice program for improving unfavorable habitual upper body postures. The impact of this intervention may extend beyond postural issues related just to online learning at home.

Prevalence of Complementary and Alternative Medicine Use and Its Associated Factors among Iranian Diabetic Patients: A Cross-Sectional Study.

Objective: This cross-sectional study aimed to assess the prevalence of complementary and alternative medicine (CAM) use and its associated factors among diabetic patients in Fasa, a city in southern Iran. Methods: Data were collected from diabetic patients who visited the endocrinology clinics at Fasa University of Medical Sciences. A structured questionnaire was administered to gather information on CAM use, including the types of CAM modalities used, and reasons for use. The patient's demographic and clinical characteristics, such as age, gender, duration of diabetes, glycosylated hemoglobin (HbA1c) levels, and quality of life (QoL) were also recorded. Descriptive statistics were used to determine the prevalence of CAM use, while logistic regression analysis was employed to identify factors associated with CAM use. Results: A total of 376 diabetic patients participated in the study, with more than 89% reporting CAM use within the past year. Herbal preparations were the most commonly used type of CAM, with a prevalence rate of 99.4%. Factors associated with CAM use included patients' psychological health, attitude towards the safety of CAM, belief in the synergistic effects of combining routine medications with CAM, and previous positive experiences with CAM. Conclusion: The high prevalence of CAM use highlights the importance of considering it in diabetes management and the need for healthcare professionals' engagement in open discussions with patients about their CAM practices. Understanding the factors influencing CAM use can inform healthcare providers and policymakers in developing appropriate strategies for integrating CAM approaches into conventional diabetes care.

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.

Home schooling during the COVID-19 pandemic: A randomized controlled trial of online exercise and ergonomics advice protocols on upper body symptoms.

BACKGROUND: Understanding of students' musculoskeletal health under home-schooling during the COVID-19 pandemic is limited. OBJECTIVES: (1) To investigate the prevalence and severity of musculoskeletal symptoms in home-schooled adolescents during the COVID-19 pandemic. (2) To evaluate the effect of an online exercise + ergonomics advice protocol on symptoms, compared with ergonomics advice alone. DESIGN: Cross-sectional symptom survey identifying eligible participants, followed by a pragmatic randomized controlled trial. SETTING: Online classes. PARTICIPANTS: Survey: 354 students (mean 16.6 years). TRIAL: 188 students with upper body musculoskeletal symptoms. INTERVENTIONS: Randomization to three groups (physical therapy exercises + ergonomics postural advice, ergonomics postural advice alone, nonintervention control) stratified by the site of symptoms (neck, shoulder, upper back). Interventions were orally delivered online (via WhatsApp) supplemented with written/illustrative material. Follow-up occurred at 8 weeks. OUTCOME MEASURES: Survey: prevalence of symptoms (Nordic Questionnaire). TRIAL: primary outcome = change in intensity of upper body symptoms (visual analogue scale); secondary outcome = number of participants reporting improvement in upper body symptoms. RESULTS: The 12-month prevalence of musculoskeletal disorders in the survey was 38% neck, 28% shoulder, and 35% upper back, with mean pain intensity of 3.6, 3.9, and 3.8, respectively, on 0-10 visual analogue scale: Two-thirds reported symptoms in multiple anatomical regions. In the trial, there was no statistically significant difference between the exercise + ergonomics group and ergonomics alone group on the primary outcome, yet both groups showed reduced symptom intensity compared with control (p < .001). More participants in the exercise + ergonomics group reported improvement than in the ergonomics advice alone group (p < .02). CONCLUSIONS: The prevalence of musculoskeletal symptoms was relatively high in home-schooled adolescents. Symptoms can be reduced by ergonomics advice with or without exercises, but the effect is enhanced by the addition of physical therapy exercises. The latter approach may be considered for improving schoolchildren's musculoskeletal health in the usual classroom setting.

Food co-consumption network as a new approach to dietary pattern in non-alcoholic fatty liver disease.

Dietary patterns strongly correlate with non-alcoholic fatty liver disease (NAFLD), which is a leading cause of chronic liver disease in developed societies. In this study, we introduce a new definition, the co-consumption network (CCN), which depicts the common consumption patterns of food groups through network analysis. We then examine the relationship between dietary patterns and NAFLD by analyzing this network. We selected 1500 individuals living in Tehran, Iran, cross-sectionally. They completed a food frequency questionnaire and underwent scanning via the FibroScan for liver stiffness, using the CAP score. The food items were categorized into 40 food groups. We reconstructed the CCN using the Spearman correlation-based connection. We then created healthy and unhealthy clusters using the label propagation algorithm. Participants were assigned to two clusters using the hypergeometric distribution. Finally, we classified participants into two healthy NAFLD networks, and reconstructed the gender and disease differential CCNs. We found that the sweet food group was the hub of the proposed CCN, with the largest cliques of size 5 associated with the unhealthy cluster. The unhealthy module members had a significantly higher CAP score (253.7 ± 47.8) compared to the healthy module members (218.0 ± 46.4) (P < 0.001). The disease differential CCN showed that in the case of NAFLD, processed meat had been co-consumed with mayonnaise and soft drinks, in contrast to the healthy participants, who had co-consumed fruits with green leafy and yellow vegetables. The CCN is a powerful method for presenting food groups, their consumption quantity, and their interactions efficiently. Moreover, it facilitates the examination of the relationship between dietary patterns and NAFLD.

An insight into the potential role of LINC00968 in luminal breast cancer: Case-control study and bioinformatics analysis.

Background: Luminal A and B subtypes of breast cancer (BC) comprises up to 70% of all BC patients. LncRNAs can affect many biological and pathological processes, and dysregulation of them is related to human cancers. The potential role of lncRNA LINC00968 in luminal BC is still unclear. Materials and methods: We analyzed the LINC00968 expression across 44 paired luminal BC tissues from the TCGA-BRCA RNA sequencing dataset. Besides, we used the GEPIA2 web server and GENEVESTIGATOR software, as well. Real-Time Quantitative Reverse Transcription PCR (qRT-PCR) assay was performed to confirm the LINC00968 expression in 71 paired luminal BC tissues and two luminal A cell lines (MCF7 and T47D). Moreover, to better understanding the potential role of LINC00968 in luminal BC, computational data analyses including co-expression analysis, functional annotation analysis, and genetic alteration analysis have been done. Results: The results of data analyses retrieved from BRCA dataset and databases revealed the significant downregulation of LINC00968 in luminal A and B BC. Also, the results of qRT-PCR in luminal BC tissues and cell lines confirmed the earlier data. LINC00968 expression was negatively associated with tumor stage and lymph node metastasis. Additionally, functional annotation analyses revealed that LINC00968 might be involved in vascular development and angiogenesis, extracellular matrix organization, and cell motility and migration. LINC00968 might play role in some cancer-related signaling pathways. Conclusion: Our study found that downregulation of LINC00968 might promote tumorigenesis, invasion, and metastasis of luminal BC.

Insilco prediction of the role of the FriZZled5 gene in colorectal cancer.

INTRODUCTION: In this study, we aimed to elucidate the crosstalk between the Wnt/ß-catenin signaling pathway and colorectal cancer (CRC) associated with inflammatory bowel disease (IBD) using a bioinformatics analysis of putative common biomarkers and a systems biology approach. MATERIALS AND METHODS: The following criteria were used to search the GEO and ArrayExpress databases for terms related to CRC and IBD: 1. The dataset containing the transcriptomic data, and 2. Untreated samples by medications or drugs. A total of 42 datasets were selected for additional analysis. The GEO2R identified the differentially expressed genes. The genes involved in the Wnt signaling pathway were extracted from the KEGG database. Enrichment analysis and miRNA target prediction were conducted through the ToppGene online tool. RESULTS: In CRC datasets, there were 1168 up- and 998 down-regulated probes, whereas, in IBD datasets, there were 256 up- and 200 down-regulated probes. There were 65 upregulated and 57 downregulated genes shared by CRC and IBD. According to KEGG, there were 166 genes in the Wnt pathway. FriZZled5 (FZD5) was a down-regulated gene in both CRC and IBD, as determined by the intersection of CRC- and IBD-related DEGs with the Wnt pathway. It was also demonstrated that miR-191, miR-885-5p, miR-378a-3p, and miR-396-3p affect the FriZZled5 gene expression. CONCLUSION: It is possible that increased expression of miR-191 and miR-885-5p, or decreased expression of miR-378a -3p and miR396-3, in IBD and CRC results in decreased expression of the FZD5 gene. Based on the function of this gene, FZD5 may be a potential therapeutic target in IBD that progresses to CRC.

Effectiveness of a school-based health education program to improve the symptoms of premenstrual syndrome in high school girls in Ilam.

BACKGROUND: The premenstrual syndrome happens periodically and affects both the individual and family. The aim of this study was to determine the effect of the health education program on reducing premenstrual syndrome in high school girls in Ilam. MATERIALS AND METHODS: This experimental study was conducted in girls' high schools in Ilam, in 2017-2018. In total, 120 students were enrolled in the study (intervention group = 61 and control group = 59) and selected through convenience sampling. In this study, a standard Premenstrual Symptoms Screening Tool (PSST) was used to diagnose students with premenstrual syndrome or Premenstrual Dysphoric Disorder (PMDD). The educational program for the intervention group was held in four sessions of 30 min for 4 consecutive weeks. The obtained data were analyzed by the SPSS statistical software at a significance level of less than 0.05. RESULTS: The results showed a significant difference in the proportion of cases with moderate and severe PMS and PMDD between intervention and control groups in follow-up (P < 0.001). However, these proportions were not significantly different between the two groups in the baseline. CONCLUSIONS: According to the results, the educational program can be recommended as an effective intervention for girls with moderate-to-severe premenstrual symptoms and premenstrual dysphoric disorder.

Effect of tofacitinib on clinical and laboratory findings in severe and resistant patients with COVID-19.

BACKGROUND: The efficacy and safety of a strong Janus kinase inhibitor, tofacitinib, in individuals suffering from severe coronavirus disease 2019 (Covid-19) pneumonia are not definite well. METHODS: In this non-randomized and non-blinded trial, a total of 52 Iranian patients with severe COVID-19 associated with decreased oxygen saturation, elevated C-reactive protein, and/or persistent fever were included. A total of 52 patients were included in this study. Tofacitinib was administered to 29 patients (55.8%) in addition to the standard care treatments, whereas 23 patients (44.2%) were treated with the standard of care alone (mostly antiviral agents and corticosteroids). Tofacitinib was administered at a dose of 5 mg twice daily for up to 10 days. The primary outcomes were mortality rate, oxygen saturation level, CT findings, rate of breath, heart rate, and level of consciousness. Inflammatory cytokines and blood biomarkers were considered as the secondary outcomes. RESULTS: Death from any cause through day 14 occurred in 51.7% of the tofacitinib group and 65.2% of the control group. There was no significant difference in lung radiographic findings between the intervention and control groups at the first day of the study and after the study period. However, a significant decrease was observed in the extent of lung tissue involvement in the intervention group after administration of tofacitinib. Regarding cell and blood biomarkers, a significant decrease in the CPK levels in the intervention group and Hct and ACE levels in the control group was observed after fourteen days of the study. Moreover, a significant increase in SGOT and ferritin values was detected in the control group 14 days after the beginning tofacitinib administration. Comparing control and intervention groups, there was a significant difference in hemoglobin, SGOT, LDH, ferritin, and ACE values between groups before the intervention, while after fourteen days of the study, no significant difference was found. In case of DHEAS and TSH levels, a significant decrease was seen in the intervention group compared to the control after the study period. No other significant improvement was detected in other outcomes of the tofacitinib group compared to the control. CONCLUSIONS: The administration of tofacitinib combined with corticosteroids, is not effective enough to treat severe COVID-19 patients and the use of this medication should be considered before the disease deterioration.

The relationship between pregnancy count and duration of breast-feeding with metabolic syndrome (Fasa Persian cohort study).

BACKGROUND: Changes that occur during pregnancy and after that during breastfeeding induce some symptoms similar to metabolic syndrome (MetS) risk factors. This study aims to determine the relationship between pregnancy, as well as the duration of breastfeeding and MetS controlling the effect of other risk factors like hypertension, glucose intolerance, triglyceride, central obesity, and reduction of high-density lipoprotein in women of Fasa Persian Cohort Study. MATERIALS AND METHODS: In this cross-sectional study, 5015 women aged 35-70 years were investigated in the Sheshdeh region from 2016 to 2021, and the information related to the disease symptoms was collected through questionnaires, examinations, and laboratory tests. MetS was calculated based on two guidelines according to adult treatment panel III (ATP III) and international diabetes federation (IDF) methods. For reporting the data, the odds ratio with its 95% confidence interval was used. In order to eliminate the effect of confounders, logistic regression was used. RESULTS: Prevalence of MetS showed a descending trend in women with up to two pregnancies and it reached 22.6% and 22.4% using ATPIII and IDF methods respectively, while with an increase in the number of pregnancies of more than two, MetS prevalence was ascending. The prevalence of MetS did not have any specific trend across various breastfeeding duration groups. Multivariate analysis approved that the odds ratio of developing MetS in comparison with women who had two pregnancies was significantly increasing trend when the pregnancy counts increased. CONCLUSION: The chance of developing MetS based on both IDF and ATP III methods after adjustment for confounding effects would grow with an increase in the number of pregnancies to more than two and breast-feeding of more than seven years. It is recommended that women with more than two pregnancies or the long duration of breast-feeding women undergo a specialized examination to investigate and control MetS problems so that future diseases could be prevented.

Rewiring of miRNA-mRNA bipartite co-expression network as a novel way to understand the prostate cancer related players.

The differential expression and direct targeting of mRNA by miRNA are two main logics of the traditional approach to constructing the miRNA-mRNA network. This approach, could be led to the loss of considerable information and some challenges of direct targeting. To avoid these problems, we analyzed the rewiring network and constructed two miRNA-mRNA expression bipartite networks for both normal and primary prostate cancer tissue obtained from PRAD-TCGA. We then calculated beta-coefficient of the regression-model when miR was dependent and mRNA independent for each miR and mRNA and separately in both networks. We defined the rewired edges as a significant change in the regression coefficient between normal and cancer states. The rewired nodes through multinomial distribution were defined and network from rewired edges and nodes was analyzed and enriched. Of the 306 rewired edges, 112(37%) were new, 123(40%) were lost, 44(14%) were strengthened, and 27(9%) weakened connections were discovered. The highest centrality of 106 rewired mRNAs belonged to PGM5, BOD1L1, C1S, SEPG, TMEFF2, and CSNK2A1. The highest centrality of 68 rewired miRs belonged to miR-181d, miR-4677, miR-4662a, miR-9.3, and miR-1301. SMAD and beta-catenin binding were enriched as molecular functions. The regulation was a frequently repeated concept in the biological process. Our rewiring analysis highlighted the impact of ß-catenin and SMAD signaling as also some transcript factors like TGFB1I1 in prostate cancer progression. Altogether, we developed a miRNA-mRNA co-expression bipartite network to identify the hidden aspects of the prostate cancer mechanism, which traditional analysis -like differential expression- was not detect it.

Female high school students' knowledge and attitude toward breast cancer.

BACKGROUND: Breast cancer is the most common cancer among women. Even though early detection and diagnosis of this disease can reduce mortality considerably, several studies have shown that more than 92% of women are unaware of the risk factors for breast cancer and of breast cancer screening tests. The simultaneous promotion of screening and provision of education can increase community health and reduce medical costs, and students can play a leading role in informing and educating people in society. AIM: The present study aims to examine the level of knowledge and attitude of female students in senior high schools in Fasa regarding breast cancer screening. METHODS: In this cross-sectional study, the random sampling method was applied to survey 350 female high school students, only 311 of whom completed the study. Questionnaires were completed in girls' high schools, and the data was analyzed by SPSS Software, Version 25. RESULTS: The results revealed that more than 87% of students were unaware or had incorrect information regarding breast cancer screening. The link between the type of breast cancer information sources and students' general knowledge was significant. Most students were aware of the risk of breast cancer, but they were uninformed of its symptoms, risk factors, and prevention strategies, and students with a family history of breast cancer had a higher score in terms of mammography knowledge than students with no family history of breast cancer, although this difference was not significant (mean ± standard deviation = 0.94 ± 0.90 vs. 0.67 ± 0.81, p = 0.19). CONCLUSION: The level of awareness and attitude of Fasa high school girls regarding breast cancer and screening methods is not acceptable. Therefore, it is recommended that educational programs be implemented to increase the awareness of students in schools, so that the number of screenings increases with the institutionalization of this information. Likewise, by transferring information through students to their families, the level of awareness in the whole society will hopefully increase as well.

Expression analysis of hsa_circ_0020397, hsa_circ_0005986, hsa_circ_0003028, and hsa_circ_0006990 in renal cell carcinoma.

Renal cell carcinoma (RCC) is a prevalent heterogeneous kidney cancer. So far, different genes have been reported for RCC development. However, its particular molecular mechanism remains unclear. Circular RNAs (circRNAs), a class of non-coding RNAs, are involved in numerous biological processes in different malignancies such as RCC. This study aims to assess the expression and underlying mechanism of four circRNAs (hsa_circ_0020397, hsa_circ_0005986, hsa_circ_0003028, hsa_circ_0006990) with possible new roles in RCC. In the experimental step, we investigated the expression of these four circRNAs in our RCC samples using quantitative real-time polymerase chain reaction. In the bioinformatics step, the differential expressed mRNAs (DEmRNAs), and miRNAs (DEmiRNAs) were obtained from the GEO datasets using the GEO2R tool. A protein-protein interaction network was constructed using the STRING database, and hub genes were identified by Cytoscape. Molecular pathways associated with hub genes were detected using KEGG pathway enrichment analysis. Then, we utilized the ToppGene database to detect the relationships between DEmiRNAs and hub genes. Furthermore, interactions between circRNAs and DEmiRNAs were predicted by the StarBase and circinteractome databases. Finally, a circRNA-DEmiRNA-hub gene triple network was constructed. Our results revealed that the expression of hsa_circ_0020397, hsa_circ_0005986, and hsa_circ_0006990 was downregulated in RCC tissues. Moreover, these circRNAs had a significantly lower expression in patients with a history of kidney disease. Furthermore, hsa_circ_0003028 and hsa_circ_0006990 showed higher expression in the tumor of participants with Lymphovascular/perineural invasion and oncocytoma type, respectively. Based on bioinformatic results, 15 circRNA-DEmiRNA-hub gene ceRNA regulatory axes were predicted, which included three hub genes, five miRNAs, and four selected circRNAs. In conclusion, the current work is the first to emphasize the expression of the hsa_circ_0020397, hsa_circ_0005986, hsa_circ_0003028, and hsa_circ_0006990 in RCC patients presents a novel perspective on the molecular processes underlying the pathogenic mechanisms of RCC.

Association of Dietary Acid Load With Metabolic Syndrome and Its Components in Iranian Adults: A Cross-Sectional Study.

Introduction Metabolic syndrome (MetS) remains one of the leading health challenges worldwide. A combination of genetic and environmental factors has been implicated in the etiology of MetS. Diet is a changeable environmental risk factor, and dietary modifications could significantly reduce the incidence and mortality of numerous diseases, including MetS. Certain dietary factors may contribute to MetS by affecting the acid-base balance within the body. This study examined the association of dietary acid load (DAL) with MetS and its components in Iranian adults. Materials and methods This cross-sectional study was conducted in 2022 on 6356 Iranian adults aged 35-70 years. Potential renal acid load (PRAL) and net endogenous acid production (NEAP) as two indicators of DAL were calculated based on nutrient intake data from validated food frequency questionnaires. MetS and its components were defined according to the Adult Treatment Panel III criteria. Logistic regression analysis was used to explore the associations between DAL and MetS and its components. Age, energy intake, physical activity, education, marital status, home ownership, socioeconomic status, history of obesity-related disease, and calcium supplements were included in model I. Further adjustment in model II was made for body mass index. Results Higher NEAP scores were associated with increased odds of low high-density lipoprotein cholesterol (HDL-C) in the crude model (OR: 1.26, 95% CI: 1.01-2.56, p trend = 0.06) in women, which was confirmed in the adjusted models. In model I, women in the last quintile of NEAP had 54% greater odds of having hypertriglyceridemia compared to the first quintile (OR: 1.54, 95% CI: 1.007-2.36, p trend = 0.02). This association was still significant and even stronger after further adjustment for BMI (OR: 1.55, 95% CI: 1.01-2.40, p trend = 0.01). In addition, in model I, men in the fourth quintile of NEAP had 5.68-fold greater odds of hyperglycemia compared to the first quintile (OR: 5.68, 95% CI: 1.18-27.25, p trend = 0.11). Similar results were found in the fully adjusted model (OR: 5.89, 95% CI: 1.19-28.99, p trend = 0.54). Conclusion There was no significant association between DAL and MetS. DAL was positively associated with the odds of low HDL-C and hypertriglyceridemia in women. Moreover, moderate DAL (NEAP) was associated with an increased odds of hyperglycemia in men.

Translation and psychometric properties of the Persian version of the Audit of Diabetes Dependent Quality of Life (IR-ADDQoL).

BACKGROUND: This study aimed to undertake linguistic validation and assess the psychometric properties of the Persian version of the Audit of Diabetes-Dependent Quality of Life (IR-ADDQoL) questionnaire in Iranian patients with type 1 and type 2 diabetes. METHODS: The gold-standard linguistic-validation procedure required by the developer of the ADDQoL (see https://www.healthpsychologyresearch.com ) including cross-cultural adaptation was followed. Validity and reliability of the Persian ADDQoL were then evaluated in a cross-sectional study of a sample of 153 patients with diabetes. Exploratory and confirmatory factor analyses were applied to assess structural validity. Internal consistency reliability was assessed. RESULTS: Both forced one-factor and unforced four-factor solutions were extracted from the exploratory factor analysis that jointly accounted for 48% and 66.53% of the variance observed, respectively. Confirmatory factor analysis indicated an acceptable model fit for the Persian ADDQoL. Cronbach's alpha showed excellent internal consistency for the questionnaire (alpha = 0.931 for the single scale). CONCLUSION: The Persian ADDQoL (IR-ADDQoL) showed adequate structural validity and excellent internal consistency. Therefore, it could be efficiently used to evaluate the impact of diabetes on quality of life in outcome studies and research settings in Iran.

The barriers to whole-grain consumption among Iranian students.

Studies show that regularly consuming whole grains reduce the risk of obesity and a wide range of chronic diseases. Despite this, studies reveal that students are consuming fewer whole grains. In the present study, we aimed to investigate the barriers to the consumption of whole grains among Iranian students. This cross-sectional study examined students at Fasa, Iran in 2020-2021. The online questionnaires were completed by students after receiving informed consent. Statistical analysis was performed using SPSS 26 and Chi-square, t-test, and logistic regression (P > 0.05). The current study involved 1890 students (1287 (68.1%) girls and 603 (31.9%) boys). Despite the preference for white flour bread among 53.8% of all students, 77.4% ate other whole-grain products, and 75.2% consumed all products at least once a week. Additionally, barriers such as access issues (70.5%), family supply issues (91.8%), lack appeal (72.8%), non-consumption by classmates (96.2%), and high prices in recent years (43.9%) were identified as obstacles to whole grain consumption. Furthermore, white bread eating students had significantly lower appetite levels and tended to eat fast food more often than those who ate whole grains (P < 0.05). We found that slightly more than half of the participants preferred to eat bread prepared with refined flour. Several other factors, including lack of access, lack of attractiveness, product price, parents not purchasing whole-grain products, students not paying attention to nutrition labels, peers' effect, and eating with friends instead of family, also contribute to students avoiding whole-grain products.

Hsa_circ_0000479/Hsa-miR-149-5p/RIG-I, IL-6 Axis: A Potential Novel Pathway to Regulate Immune Response against COVID-19.

Background: COVID-19, the disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has led to a global pandemic and mortality of people around the world. Some circular RNAs (circRNAs), one of the new types of noncoding RNAs (ncRNAs), act as competing endogenous RNAs (ceRNAs) and compete with mRNAs for shared miRNAs, to regulate gene expression. In the present study, we aimed to evaluate the expression and roles of hsa_circ_0000479/hsa-miR-149-5p/RIG-I, IL-6 in COVID-19 infection. Materials and Methods: After extraction of total RNA from peripheral blood mononuclear cells (PBMC) of 50 patients with symptomatic COVID-19, 50 patients with nonsymptomatic COVID-19, and 50 normal controls, cDNA synthesis was performed. Online in silico tools were applied to evaluate the interaction between the genes in the hsa_circ_0000479/hsa-miR-149-5p/RIG-I, IL-6 axis, and its role in COVID-19-related pathways. Quantification of the expression of these genes and confirmation of their interaction was done using the quantitative real-time PCR (qRT-PCR) technique. Results: The expression levels of hsa_circ_0000479, RIG-I, and IL-6 were increased in COVID-19 patients compared to healthy controls, while hsa-miR-149-5p expression was decreased. Moreover, there was a significant negative correlation between hsa-miR-149-5p and hsa_circ_0000479, RIG-I, IL-6 expressions, and also a positive expression correlation between hsa_circ_0000479 and IL-6, RIG-I. Then, bioinformatics tools revealed the role of hsa_circ_0000479/hsa-miR-149-5p/RIG-I, IL-6 axis in PI3K-AKT and STAT3 signaling pathways. Conclusion: Upregulation of hsa_circ_0000479, RIG-I, and IL-6, and downregulation of hsa-miR-149-5p, along with correlation studies, indicate that hsa_circ_0000479/hsa-miR-149-5p/RIG-I, IL-6 axis could play a role in regulating the immune response against SARS-CoV-2. However, more studies are needed in this area.
