Background: The implication of gut microbiota in the gut-kidney axis affects the pathophysiology of chronic kidney disease (CKD). Gut microbiota composition changes during CKD. We aimed to determine the relative frequency of important gut microbiota members in end-stage renal disease (ERSD) patients before and after renal transplantation compared to healthy subjects. Methods: Fifteen kidney transplant patients and 10 healthy subjects were recruited in this case-control prospective study. Fecal samples were taken sequentially from all patients before kidney transplantation, 1 week, and 1 month after it. The relative frequency of Lactobacillus spp., Bifidobacterium spp., Akkermansia muciniphila, Bacteroides fragilis, Escherichia coli, and Faecalibacterium pruasnitzii were determined through quantitative PCR. The obtained data was statistically analyzed by Stata software (Stata Corporation, USA). Results: The mean log number of all bacteria was significantly higher in healthy individuals than kidney transplant recipients (p < 0.001) except for Lactobacillus where the mean levels were almost identical in the two groups (p = 0.67). Moreover, 20% (3) of patients developed a urinary tract infection. Besides, 2 (13.33%) patients were diagnosed with delayed graft function. There were no statistically significant differences regarding changing trends in bacteria log number of Akkermansia muciniphila (p = 0.12), Bacteroid fragilis (p = 0.75), Bifidobacterium (p = 0.99), Escherichia coli (p = 0.5), Faecalibacterium (p = 0.98), and Lactobacilli (p = 0.93) between patients with and without delayed graft function (DGF). Conclusion: Gut microbiota composition in patients with ESRD was significantly different from those without it. However, the microbiota profile did not significantly differ in patients with and without DGF. [ABSTRACT FROM AUTHOR]

Background and objectives: This study aimed to investigate the possible prognostic significance of interferon alpha--beta receptor subunit 2 (IFNAR2) and tyrosine kinase 2 (TYK2) expressions. Methods: We conducted a retrospective study including COVID-19 adult patients. All blood samples were collected before any interventions. The expressions of IFNAR2 and TYK2 were assessed using real-time PCR in venous blood samples of 54 cases and 56 controls. The transcript quantities of IFNAR2 and TYK2 genes were assessed using a Delta-Ct method. Results: Our findings show no significant differences in gene expression levels for IFNAR2 and TYK2 between patients who required oxygen (O2) therapy and thosewho did not (p-value = 0.732 and p-value = 0.629, respectively). Likewise, there were no significant differences in IFNAR2 and TYK2 expressions between patients hospitalized for less than 7 days and those hospitalized for 7 days or more (p-value = 0.455 and pvalue = 0.626, respectively). We also observed a weak correlation between IFNAR2 expression and CRP (p-value = 0.045, r = 0.192). There was a negative correlation between the expression levels of IFNAR2 and TYK2 transcripts in COVID-19 patients (p-value = 0.044; partial correlation coefficient = -0.283). Additionally, IFNAR2 and TYK2 were significantly downregulated in the COVID-19 group compared to healthy subjects (p-value = 0.002 and p-value = 0.028, respectively). However, neither IFNAR2 nor TYK2 expression was significantly different between the case subgroups based on COVID-19 severity. The IFNAR2 DDCt (B = -0.184, 95% CI: - 0.524--0.157, p-value = 0.275) and the TYK2 DDCt (B = 0.114, 95% CI: -0.268--0.496, p-value = 0.543) were not found to be significant predictors of hospitalization duration. The area under the curve (AUC) for IFNAR2 expression is 0.655 (p-value = 0.005, 95% CI: 0.554--0.757), suggesting its poor discriminative value. Conclusion: We were unable to comment definitively on the prognostic power of IFNAR2 and TYK2 expressions in COVID-19 patients, and larger-scale studies are needed. The principal limitations of this study included the lack of longitudinal analysis and limited sample size. [ABSTRACT FROM AUTHOR]

Background: Rheumatoid arthritis (RA) and low back pain (LBP) are among the most prevalent musculoskeletal disorders (MSDs). The need for investigation of regional and local patterns of these two MSDs seems inevitable for better policy‐making. The current study presents updated results of the Global Burden of Disease (GBD) Study 2019 and reports the burden of RA and LBP in North Africa and Middle East (NAME) countries from 1990 to 2019. Methods: Incidence, prevalence, mortality, years of life lost (YLLs), years lived with disability (YLDs), disability‐adjusted life‐years (DALYs), and risk factors, including high body mass index, occupational ergonomic factors, and smoking, were extracted based on the GBD 2019 data. Results: The age‐standardized prevalence and mortality of RA were 120.6 (95% uncertainty interval [95% UI] 107.0–135.7) and 0.1 (95% UI 0.1–0.2) per 100 000 population in 2019 with 28.3% (95% UI 25.5%–30.9%) increase and 7.5% (95% UI −37.5% to 32.5%) decrease since 1990, respectively. Turkey had the highest age‐standardized incidence, prevalence, and DALYs of RA in 2019. All RA burden measures were higher for women; however, the incidence was almost the same at ages greater than 65 years. The age‐standardized prevalence and DALYs of LBP were 7668.2 (95% UI 6798.0–8636.3) and 862 (95% UI 605.5–1153.3) in 2019, which had decreased by 5.8% (95% UI −7.4% to −4.3%) and 6.0% (95% UI −7.7% to −4.2%) since 1990, respectively. Moreover, although Turkey had the highest incidence and prevalence in 1990, Iran was at the top in 2019. The regional age‐standardized DALY rates due to RA and LBP attributed to smoking were 1.7 (95% UI 0.5–3.2) and 139.4 (95% UI 87.3–198.8) in 2019, respectively, which had decreased 2.2% (95% UI −19.2% to 13.7%) and 15.4% (95% UI −19.4% to −10.5%) since 1990, respectively. Conclusion: RA still imposes a significant burden in the NAME region as the burden measures have increased from 1990 to 2019. On the other hand, regarding LBP, a decreasing pattern was observed. Differences among the countries and between ages and genders can have implications, and the results of this study may be helpful for policy‐makers in the NAME countries. [ABSTRACT FROM AUTHOR]

Background & Objective: Prostatic adenocarcinoma (PAC) is one of the most common tumors worldwide. Immunohistochemical expression of cytokeratins has been evaluated in the diagnosis and prognosis of tumors. The aim of the present study is the evaluation of Cytokeratin-7 (Ck-7) and Cytokeratin-19 (Ck-19) expression and its relationship with Gleason score in patients with PAC. Methods: In this cross-sectional study, 78 samples from 78 patients with PAC referred to Mostafa Khomeini Hospital were gathered. Samples were immunohistochemically stained by Ck-7 and Ck-19 markers. The percentage of each marker in tumor cells was determined, and its relationship with Gleason scores and Gleason grade groups was analysed by SPSS version 24. Results: The expression of Ck-7 and Ck-19 were seen in 37.2% and 82.1% of samples, respectively. The mean of Ck-7 expression in tumor cells was 4.98%±7.19 (ranged 0 to 26%), while the mean of Ck-19 expression was 41.02%±23.36 (ranged 0 to 78%). There was no relationship between Ck-7 expression with Gleason scores and Gleason grade groups. However, Ck-19 expression was increased in higher Gleason scores and Gleason grade groups (P<0.001). No relationship was found between age and Ck-7 (P=0.309) and Ck-19 (P=0.375). Conclusion: The Ck-7 expression in PAC samples is weak and focal and had no relationship with the Gleason scores and Gleason grade groups. However, Ck-19 expression in PAC was high and was associated with tumor dedifferentiation of samples. There was no relationship between the expression of both markers with the patient's age.

Manifestations caused by coronavirus family have presented it in many ways during the previous years. The aim of this systematic review was to gather all possible cardiovascular manifestations of the coronavirus family in the literature. Adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched PubMed, Scopus, Web of Science, Cochrane and ProQuest which were updated on May 1, 2020 for the last time. Regarding to the novelty and speed of publications on COVID-19, we searched Google Scholar and also references of included studies and review articles in the systematic search results were searched manually. The searched keywords were the combination of the following MeSH terms: "COVID-19", "SARS", "MERS" and "cardiovascular presentation". The systematic review was registered with ID CRD42020180736 in International Prospective Register of Systematic Reviews (PROSPERO). After screening, 28 original articles and ten case studies (five case reports and five case series) were included. Most of the studies were focused on COVID-19 (20 original articles and five case studies) while the only studies about Middle East Respiratory Syndrome (MERS) was a case report. Almost all the cardiovascular presentations and complications including acute cardiac injury, arrhythmias and the thrombotic complications were more prevalent in COVID-19 than severe acute respiratory syndrome (SARS) and MERS. The cardiac injury was the most common cardiovascular presentation and complication in COVID-19 whereas thrombotic complications were commonly reported in SARS. The cardiac injury was the predictor of disease severity and mortality in both COVID-19 and SARS. Coronavirus 2019 may present with cardiovascular manifestations and complications in signs and symptoms, laboratory data and other paraclinical findings. Also, cardiovascular complications in the course of COVID-19 may result in worse outcomes. [ABSTRACT FROM AUTHOR]

Background: The 2019 coronavirus disease (COVID-19) is threatening public health in many ways. The psychological situation of individuals is important and limited data is available from Iran. In this study, we aimed to illustrate the psychological distress of the general population and evaluate the factors affecting it. Methods: An online cross-sectional survey was conducted from 29th to 31st March 2020 in South Khorasan province, affected later than other parts of the country. We included sociodemographic questions, Hospital Anxiety, and Depression Scale (HADS) questionnaire, and questions addressing various symptoms and diseases. Most questions had multiple choices to select from and some were open questions. Univariate and multivariate analysis in SPSS software was used to find significant relationships. Results: A total of 844 responses were collected, of which 788 records were included in the analysis. The mean age of responders was 36.61±10.97 (age range: 18-88) and 484 (61.4%) of them were females. The mean scores in the anxiety and depression subscale of the HADS questionnaire were 7.01±3.68 and 6.72±3.71 respectively. Experiencing cardiovascular and COVID-19 related symptoms was significantly associated with a higher number of individuals having abnormal anxiety and depression results (p<0.001). Widowed individuals, females, and those experiencing the above-stated symptoms showed a significant association with increased anxiety and depression in multivariate analysis. Conclusion: Although many existing elements influence the psychological well-being of society during a pandemic, experiencing symptoms related to other diseases or having multiple chronic diseases may cause an extra burden on the psychological state of the society.

Purpose: Breast cancer survivors (BCSs) tend to have sleep disturbances such as obstructive sleep apnea (OSA). However, limited evidence exists on the role of breast cancer-related lymphedema (BCRL) in sleep disturbances and OSA. Therefore, this study aimed to investigate the quality of sleep (QoS) and OSA risk among women with and without BCRL., Methods: The quality of life (QoL) was evaluated using the SF-12 and EORTC-QLQ C-30 questionnaires, while their sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI) questionnaire. The STOP-bang questionnaire (SBQ) was utilized to quantify OSA risk. Sleepiness was assessed using the Epworth Sleepiness Scale (ESS). Also, neck and waist circumference and the excessive volume in the affected limb were measured using a tape measure. The statistical analyses were performed using the SPSS 21.0 software., Results: Seventy-one women with BCRL and 84 BCS without lymphedema were included. The comparison of PSQI, SBQ, ESS, SF-12, and EORTC QLQ-C30 questionnaires exhibited no significant difference between these two groups. The overnight snoring and average neck circumference were significantly higher in the BCRL group than in the control. The BCRL stage significantly correlated with neck circumference and SBQ total score. Additionally, the mean volume difference indicated a significant correlation with the ESS total score and both physical and mental summary components of the SF-12 questionnaire., Conclusion: The prevalence of sleep disturbances among BCSs with and without BCRL is high. Women with advanced stages of BCRL might be at high risk for OSA. Therefore clinical evaluation of BMI, neck circumference, and, snoring overnight should be emphasized among this population., Competing Interests: Declarations.

Purpose: Trabecular bone score (TBS), as a texture indicator of bone microarchitecture, predicts the risk of fracture. This study aims to explore the knowledge map of TBS., Methods: We searched Scopus for "trabecular bone score" or "trabecular score" from the beginning to 2021. Our inclusion criteria were original articles and reviews that were related to TBS and our exclusion criteria were non-English articles, non-related to TBS, and document type other than original articles and reviews. and related documents were included for bibliometric analysis. Excel, VOS viewer, and Science of Science (Sci2) software were used for data synthesis., Results: From 749 retrieved articles, 652 articles were included for analysis. These documents were cited 12,153 times and had an H-index of 56. The most productivity belonged to the USA (n = 130 documents), Switzerland (n = 101), and Italy (n = 67). "Osteoporosis International" (n = 80) had the highest participation in publishing. The research topics of interest were mainly related to the applicability of TBS for fracture risk assessment in chronic endocrine disorders such as osteoporosis and diabetes mellitus. Bursting analysis of the title and abstract revealed the initial focus of the discriminative power of TBS for osteoporotic fracture and the more recent focus on comparing bone mineral density (BMD) and TBS in a variety of chronic diseases., Conclusion: The number of annual publications on TBS has increased, especially after 2016. These publications highlight the importance of in-depth knowledge of TBS in predicting fracture risk and also its strengths and limitations of treatment monitoring in different health conditions., Supplementary Information: The online version contains supplementary material available at 10.1007/s40200-023-01338-7., Competing Interests: Competing interestsThe authors declare that they have no competing interests., (© The Author(s), under exclusive licence to Tehran University of Medical Sciences 2023.

Context: There has been an increasing emphasis on the role of education in diabetes prevention and management, and shedding light on evidence gaps is mandatory for national action plans establishment., Data Sources: This scoping review was part of the Iranian Diabetes Road Map project that used a systematic method based on the Arksey and O'Malley approach., Results: After the screening, 173 articles were included, most of which were published in 2018 and focused on self-management. Most included articles were considered patient-related self-management/care/efficacy, while only a limited number of articles studied healthcare provider education and educational establishment. Additionally, a significant number of included studies were addressed virtual education, an issue as the strength of Iranian studies in diabetes education., Conclusions: Education is an important part of diabetes, and specific needs for Iranian patients should be addressed in future studies. Paying attention to new topics and conducting high-quality interventional studies will help fill evidence gaps in this field in Iran., Competing Interests: Conflict of Interests: There was no conflict of interest., (Copyright © 2021, International Journal of Endocrinology and Metabolism.)

Context: The important role of physical activity in the prevention and management of diabetes necessitates a review of current research to shed light on gaps in national diabetes guidelines., Evidence Acquisition: This scoping review was part of the Iran Diabetes Research Roadmap (IDRR) study. A systematic search was used based on the Arksey and O'Malley method consisting of six steps. The descriptive analysis was done with SPSS software. Additionally, VOS veiwer software was used to draw the knowledge map of the included studies., Results: There were 169 articles included from the beginning of 2015 to the end of 2019 in Iran. Aerobic and resistance exercises were types of physical activity with more number of articles. Most of the included clinical studies were randomized clinical trials and had a level of evidence two. Also, there was more interest in outcomes such as glycemic control and insulin sensitivity, metabolic syndrome, metabolism, and cardiovascular health. The network of co-authorship was drawn, and "controlled study", "male", and "rat" were the most frequent keywords., Conclusions: The number of Iranian diabetes researchers on physical activity is increasing, and the majority of clinical studies had a high level of evidence. With maintaining previous interests and investigations, there should be more emphasis on research in elderly and children age groups as evidence gap in Iran. Also, longitudinal cohort studies should be highlighted and Iranian researchers should be encouraged to participate in new topics of research worldwide., Competing Interests: Conflict of Interests: Nothing to declare., (Copyright © 2021, International Journal of Endocrinology and Metabolism.)

Purpose: We investigated the research conducted on osteoporosis at EMRI to provide practical implications and suggestions for the development of future research., Methods: We searched osteoporosis and related concepts, as well as various forms of affiliations to EMRI to find published documents indexed in Web of Science, PubMed, and Scopus databases until January 27, 2020. The main purpose and scopes of the studies were classified into seven main study areas. Co-authorship relations were examined using the VOSviewer and keyword analysis was carried out by the ScientoPy., Results: A total 201 papers on the subject of osteoporosis with organizational affiliation to EMRI were found after initial screening and removing duplicates. A time trend analysis of publications showed a growing trend of EMRI's publication in the field of osteoporosis since 2014. A total of 558 independent authors participated in osteoporosis-related research at EMRI, and the average contribution of authors was 6.72 per papers. The Co-authorship network for authors contributing in at least five publications, showed 4 main clusters of independent authors. The co-occurrence network of keywords included three large and intertwined clusters including the epidemiology of osteoporosis and its resulting fractures and risk factors, bone markers and monitoring the effectiveness of treatment with them, and nutrition and supplements in the field of osteoporosis and fractures., Conclusion: EMRI has significantly contributed in osteoporosis science and related subjects during recent years, especially in public health aspects of osteoporosis and its risk factors and consequences. More attention should be paid to other areas such clinical and basic science studies., Competing Interests: Conflicts of interest/competing interestsKK, NF, FH, MS, NM, BL, and AO are affiliated to EMRI., (© Springer Nature Switzerland AG 2020.)
