Gut microbiota alterations in renal transplant recipients and the risk of urinary tract infection and delayed graft function: A preliminary prospective study.

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.

What is the link between the dietary inflammatory index and the gut microbiome? A systematic review.

PURPOSE: One highlighted pathogenesis mechanism of diseases is the negative impact of pro-inflammatory diets (PD) on the gut microbiome. This systematic review aimed to study the link between dietary inflammatory index (DII), as an indicator of PD, and gut microbiome. METHODS: A systematic search was done in PubMed and Scopus, adhering to the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analysis. The assessment of the included studies' quality was performed using the critical appraisal checklist from the Joanna Briggs Institute. RESULTS: Ten articles were included eight cross-sectional, one case-control, and, one cohort study. Seven and three included articles reported a weak and moderate relationship between gut microbiome and DII scores, respectively. DII scores were linked to variety in microbiome composition and diversity/richness. More importantly, anti-inflammatory diets as measured by lower DII scores were linked to a more desirable gut microbiome profile. Prevotella stercorea, Veillonella rogosae, Morganella morganii, Ruminococcus torques, Eubacterium nodatum, Alistipes intestine, Clostridium leptum, Morganellaceae family, Enterobacteriaceae family, and, Bacteroides thetaiotaomicron were related to higher DII scores. While, Butyrate-producing bacteria such as Ruminococcaceae and Lachnospiraceae families, Faecalibacterium prausnitzii, and Akkermansia muciniphila were related to lower DII scores. CONCLUSION: An anti-inflammatory diet, as measured by a lower DII score, might be linked to variations in the composition and variety of the microbiome. Therefore, the DII score could be useful in microbiota research, however, this possibility needs to be investigated more precisely in future studies.

Bibliometric analysis of publications on trabecular bone score (TBS).

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.

Thirty-three-year follow-up of pseudoaneurysm of the mitral-aortic intervalvular fibrosa without surgical treatment: a case report and literature review.

BACKGROUND: Pseudoaneurysm of the mitral-aortic intervalvular fibrosa (PMAIF) is a rare complication of infective endocarditis or aortic valve surgery. Surgical treatment is suggested, but the long-term follow-up of conservative management remains unclear. CASE PRESENTATION: A 33-year follow-up of a patient who developed PMAIF six years after aortic valve replacement is reported. The patient presented to our center with dyspnea, and the echocardiography revealed an ejection fraction of 20% and a PMAIF measuring 7 × 10 mm. Despite being advised to undergo surgery, the patient declined due to fear of surgical outcomes. Consequently, conservative treatment with close observation but without surgery was initiated. During the 33-year follow-up period, the patient did not experience any adverse health effects. CONCLUSION: Surgical intervention should be considered whenever the PMAIF is diagnosed. However, in any case that the surgery was not applicable, conservative management might lead to long-term survival, based on this and similar case reports in the literature.

Evaluation of IFNAR2 and TYK2 transcripts' prognostic role in COVID-19 patients: a retrospective study.

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 those who 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 p-value = 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 ΔΔCt (B = -0.184, 95% CI: -0.524-0.157, p-value = 0.275) and the TYK2 ΔΔCt (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.

Lymphedema after saphenous harvesting for coronary artery bypass surgery: case report and literature review.

Different causes have been described for secondary lymphedema as reported in this article. A 75-year-old man was diagnosed with lymphedema about one decade after saphenous harvesting for coronary artery bypass surgery. It took two years for him to find out his diagnosis and receive the proper treatment. After standard complete decongestive therapy, his volume and pain decreased and his quality of life was improved, especially its physical aspect. It is important to recognize the possibility of lymphedema development after saphenous harvesting among patients undergoing coronary artery bypass surgery to prevent significant disturbance of quality of life with timely management.

Evaluation of Cytokeratin-7 and Cytokeratin-19 Expression Relationship with Gleason Score in Prostatic Adenocarcinoma.

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.

Mind the osteoporosis care gap with timely diagnosis: an executive summary of nationwide osteoporosis Campaigns 2019-2021.

Background: The World Osteoporosis Day inaugurate on October 20 every year by the International Osteoporosis Foundation to initiate bone health and osteoporosis as a global health agenda for policymakers, health care providers, and the public. The reported the campaigns activities in three years 2019, 2020, and 2021. The aim of this campaigns was to promote the osteoporosis awareness to close osteoporosis care and data gaps. Methods: World Osteoporosis Day campaigns were held during three consecutive years 2019-2021 through "structuring" and "implantation" phases. The slogan of "early detection and timely diagnosis of osteoporosis" was followed in different public awareness and healthcare professional educational events. Also, a short survey regarding the knowledge of women aged ≥ 50 years of osteoporosis was used in campaigns to gather data for future planning. These nationwide campaigns was supported by the Osteoporosis Research Center in collaboration with the non-communicable diseases management office of Iran's Ministry of Health. Results: All activities stablished to close the "data" and "awareness" gap in osteoporosis care. 1972, 1881, and 2538 women aged ≥ 50 were participated in the world osteoporosis campaigns and educated in 2019, 2020, and 2021, respectively. More than thousands of online and published educational materials were provided and disseminated in group and face-to-face and virtual education via celebration meetings in primary healthcare facilities, parks and shopping malls. The wide-ranging health slogans and massages was distributed by way of SMS, press conferences on television, radio, and other social media platforms. In addition, the in-person and virtual events such as up-date osteoporosis symposiums, national osteoporosis research network meetings, osteoporosis essential courses, and subspecialty one-day seminars provided knowledge for health care teams and policy makers. Conclusion: Closing the osteoporosis treatment gap was approached by nationwide campaigns to make an appropriate intervention to emphasize early diagnosis and awareness of osteoporosis to close the care gap.

The burden of rheumatoid arthritis and low back pain in North Africa and Middle East from 1990 to 2019: Results from the Global Burden of Disease Study 2019.

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.

Exposure to the COVID-19 news on social media and consequent psychological distress and potential behavioral change.

Exposure to coronavirus disease 2019 (COVID-19) news pandemic is inevitable. This study aimed to explore the association between exposure to COVID-19 news on social media and feeling of anxiety, fear, and potential opportunities for behavioral change among Iranians. A telephone-based survey was carried out in 2020. Adults aged 18 years and above were randomly selected. A self-designed questionnaire was administered to collect information on demographic variables and questions to address exposure to news and psychological and behavioral responses regarding COVID-19. A multivariate logistic regression analysis was performed to assess the relationship between anxiety, fear, behavioral responses, and independent variables, including exposure to news. In all, 1563 adults participated in the study. The mean age of respondents was 39.17 ± 13.5 years. Almost 55% of participants reported moderate to high-level anxiety, while fear of being affected by COVID-19 was reported 54.1%. Overall 88% reported that they had changed their behaviors to some extent. Exposure to the COVID-19 news on social media was the most influencing variable on anxiety (OR 2.21, 95% CI 1.62-3.04; P < 0.0001), fear (OR 1.95, 95% CI 1.49-2.56; P < 0.0001), and change in health behaviors (OR 2.02, 95% CI 1.28-3.19; P = 0.003) in the regression model. The fear of being infected by the COVID19 was associated with the female gender and some socioeconomic characteristics. Although exposure to the COVID-19 news on social media seemed to be associated with excess anxiety and fear, it also, to some extent, had positively changed people's health behaviors towards preventive measures.

Characteristics of HHV-7 meningitis: a systematic review.

There are limited data on HHV-7 meningitis and this systematic review used electronic search to gather pieces of evidence regarding its characteristics. Nine articles were included which three were case reports and the rest of the articles were retrospective studies. Altogether, 32 cases were described in the literature that 13 were females and 26 were aged less than 16 years old. The HHV-7 meningitis has been reported in any season, especially in winter. It affected both immunocompetent and immunocompromised individuals and mostly presented with fever and headache, however rash and seizure have also been documented. The CSF analysis in general showed an elevated range of cell count with lymphocytic predominance and normal to slightly elevated protein levels. Thirteen patients did not receive treatment for HHV-7 meningitis and full recovery was gained in the majority of cases after about 10 days. This review summarizes characteristics of HHV-7 meningitis in the literature, and yet epidemiological studies are needed to shed more light which eventually could be helpful for the diagnosis and management of this disease.

Long-term outcome of patients with transposition of the great arteries and a systemic right ventricle: A systematic review and meta-analysis.

BACKGROUND: Patients with a transposition of the great arteries (TGA) and a systemic right ventricle are at risk of heart failure (HF) development, arrhythmia and early mortality. Prognostic evaluations in clinical studies are hampered by small sample sizes and single-centred approaches. We aimed to investigate yearly rate of outcome and factors affecting it. METHODS: A systematic literature search of four electronic databases (PubMed, EMBASE, Web of Science and Scopus) was conducted from inception to June 2022. Studies reporting the association of a systemic right ventricle with mortality with a minimal follow-up of 2 years during adulthood were selected. Incidence of HF hospitalization and/or arrhythmia were captured as additional endpoints. For each outcome, a summary effect estimate was calculated. RESULTS: From a total of 3891 identified records, 56 studies met the selection criteria. These studies described the follow-up (on average 7.27 years) of 5358 systemic right ventricle patients. The mortality incidence was 1.3 (1-1.7) per 100 patients/year. The incidence of HF hospitalization was 2.6 (1.9-3.7) per 100 patients/year. Predictors of poor outcome were a lower left ventricular (LV) and right ventricular ejection fraction (RVEF) (standardized mean differences (SMD) of -0.43 (-0.77 to -0.09) and - 0.85 (-1.35 to -0.35), respectively), higher plasma concentrations of NT-proBNP (SMD of 1.24 (0.49-1.99)), and NYHA class ≥2 (risk ratio of 2.17 (1.40-3.35)). CONCLUSIONS: TGA patients with a systemic right ventricle have increased incidence of mortality and HF hospitalization. A lower LVEF and RVEF, higher levels of NT-proBNP and NYHA class ≥2 are associated with poor outcome.

Meningitis associated with HHV-7 in an Iranian immunocompetent adolescent girl.

There is limited literature regarding meningitis associated with HHV-7. This article reports an immunocompetent adolescent girl who developed fever, headache, and meningism which CSF molecular analysis with PCR was positive only for HHV-7. Interestingly, persistent cavum septum pellucidum and cavum vergae were observed on brain magnetic resonance imaging. The patient received antibiotics, dexamethasone, and acyclovir and then she gained full recovery. HHV-7 is a rare and yet possible pathogen in patients with meningitis, and this is the first described case report from Iran.

The association of opioid consumption and osteoporosis in old men: Bushehr Elderly Health (BEH) program.

In a population of 1156 men aged ≥ 60 years, opioid drug use was reported by 4.1% (n = 47) of participants. Among opioids, opium was the most prevalent consuming drug (83%). Adjusting for potential confounders, opioid consumption showed a positive association with osteoporosis. PURPOSE: Limited evidence suggest a relationship between opioid consumption and osteoporosis. This study aims to investigate the possible association of osteoporosis and drug use among older adult men of Bushehr, Iran. METHODS: In this study, 1156 men aged ≥ 60 years of Bushehr Elderly Health (BEH) were included. Bone density and trabecular bone score (TBS) were measured using dual-energy X-ray absorptiometry. Total osteoporosis was noted based on osteoporosis at either site of the lumbar spine, femoral neck, and total hip densitometry. Drug use was defined as a self-reported current use of opioid drugs, either regular (daily) use or irregular consumption. Multivariable modified Poisson regression analysis was used for investigating the association of opioids and osteoporosis, reporting the adjusted prevalence ratio (APR) with 95% confidence interval (CI). The association between drug use and TBS was evaluated using a linear regression model. RESULTS: Opioid drug use was reported by 4.1% (n = 47) of participants. Among drug users, opium was the most prevalent consuming drug (83%). In all, 38.3% of drug users and 22.4% of non-users had osteoporosis (p-value = 0.011). Multivariable analysis showed that adjusting by age, education, smoking, alcohol consumption, body mass index, diabetes, and physical activity, a positive and significant association was detected between opioid drug use and the likelihood of osteoporosis (APR: 1.46, 95%CI: 1.02-2.10). Considering the potential confounders, the results also showed a negative association between drug consumption and TBS (ß: - 0.027, 95%CI: - 0.053, - 0.001). CONCLUSION: Opioid drug use has a positive association with osteoporosis in elderly men, independent of other conventional risk factors. Elderly drug users might be at a higher risk for osteoporotic fractures, given the effect of substance use on cognition. So, osteoporosis among drug users would be of importance, especially in countries where opium consumption is prevalent.

Pharmacologic therapies of pain in patients with spinal cord injury: a systematic review.

STUDY DESIGN: Systematic review. OBJECTIVES: This systematic review evaluates all randomized clinical trials (RCTs) conducted on assessing the efficacy and safety of pharmacologic therapies for the treatment of Spinal Cord Injury (SCI)-associated pain. METHODS: The PubMed/Medline, EMBASE, and Cochrane library online databases were searched from 1946 to May 2019 using specific search terms for SCI, pain, and RCTs meeting predetermined inclusion criteria. The efficacy outcome of interest was pain reduction, discontinuations, and adverse events (AEs). RESULTS: Of 2746 records identified through database searching, 703 duplicates were deleted. 1814 were excluded, the full text of the remaining 230 articles was reviewed, and finally, 28 papers were selected for drafting. The most studied medications were pregabalin, gabapentin, amitriptyline, and ketamine. Pregabalin, gabapentin, and amitriptyline reduced VAS by more than 30%, and ketamine reduced VAS by 40%. Oxcarbazepine, lamotrigine, alfentanil, tramadol, and morphine added to clonidine, baclofen, and botulinum toxin type A (BTA) significantly reduced pain compared with placebo. On the other hand, valproate, levetiracetam, trazodone, and duloxetine did not significantly alleviate SCI-associated pain compared to placebo. The risks of AEs and discontinuations in anticonvulsants were the least, while it was highest in analgesics. CONCLUSIONS: Studies of SCI-associated pain were few, small, heterogenic in measures and values, and did not allow quantitative comparisons of efficacy. However, available data suggested pregabalin and gabapentin led to a more marked reduction in SCI-associated pain with fewer AEs. Additional clinical studies are needed to assess the effect of established and novel management options.

Empowering Health Care Providers and Self-management Education in Diabetes? A Scoping Review.

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.

Diabetic foot self-care practice in women with diabetes in Iran.

BACKGROUND AND AIMS: The present study was conducted to determine the situation of foot self-care practice among Iranian women with diabetes. METHODS: In this cross-sectional study, 475 women completed the Diabetic Foot Self-Care Questionnaire (DFSQ) along with other questions. The overall and three components scores including personal care, podiatric care, and foot wearing, were calculated and their relationship with other factors was analyzed. RESULTS: The average total DFSQ score was 60.38 ± 9.9, and 16.98 ± 7, 5.95 ± 2.11, and 12.26 ± 3.95 for personal care, podiatric care, and footwear respectively. Education level, self-reported health status, and life satisfaction had a significant relationship with footwear score, and smoking and life satisfaction were related to personal care and podiatric care respectively. In Pearson regression, DM self-care was correlated with all three components and total DFSQ score. Also, depression and SCS (Social Capital Status) correlated with DFSQ scores except with personal self-care and footwear respectively. Body Mass Index (BMI) and Quality of Life (QoL) were significantly correlated with footwear and podiatric care scores. CONCLUSION: In this study, the DFSQ result was almost acceptable, however, it highlights the importance of suitable interventions to establish better self-care practice among Iranian diabetic women.

Comparison of the cardiovascular presentations, complications and outcomes following different coronaviruses' infection: A systematic review.

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 four case studies) while the only studies about Middle East Respiratory Syndrome (MERS) were a case report and a case series. 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.

Evidence Gap and Knowledge Map of Physical Activity Research in Diabetes in Iran: A Scoping Review.

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.
