Abstract
The objective of this study was to identify bacteria from the rhizosphere of the black saxaul (Haloxylon ammodendron) and test the possibility of using the bacteria for enhancement of drought and/or salt tolerance in the model plant, Arabidopsis thaliana. We collected rhizosphere and bulk soil samples from a natural habitat of H. ammodendron in Iran and identified 58 morphotypes of bacteria that were enriched in the rhizosphere. From this collection, we focused our further experiments on eight isolates. Microbiological analyses showed that these isolates have different levels of tolerance to heat, salt, and drought stresses, and showed different capabilities of auxin production and phosphorous solubilization. We first tested the effects of these bacteria on the salt tolerance of Arabidopsis on agar plate assays. The bacteria substantially influenced the root system architecture, but they were not effective in increasing salt tolerance significantly. Pot assays were then conducted to evaluate the effects of the bacteria on salt or drought tolerance of Arabidopsis on peat moss. Results showed that three of these bacteria (Pseudomonas spp. and Peribacillus sp.) effectively enhanced drought tolerance in Arabidopsis, so that while none of the mock-inoculated plants survived after 19 days of water withholding, the survival rate was 50-100% for the plants that were inoculated with these bacteria. The positive effects of the rhizobacteria on a phylogenetically-distant plant species imply that the desert rhizobacteria may be used to enhance abiotic stress in crops.

Abstract
BACKGROUND Metabolic dysfunction-associated fatty liver disease (MAFLD) is a novel term that distinguishes patients at risk of adverse clinical outcomes with higher accuracy than those with non-alcoholic fatty liver disease (NAFLD). Cardiovascular mortality is the leading cause of death in MAFLD. The current literature lacks large-scale prospective studies that address preventive approaches for cardiovascular health in MAFLD. We investigated whether MAFLD patients benefit from a fixed-dose combination therapy (Aspirin, hydrochlorothiazide, atorvastatin, valsartan), known as a Polypill. METHODS Analysis was performed (stratified based on MAFLD status) of a clinical trial that included 1596 individuals randomly allocated to an intervention (polypill) or a control (usual care) group. Patients were followed up for five years for any adverse drug reaction, major cardiovascular events, and mortality. Univariable and multivariable survival analyses were performed, and the interaction level was assessed by R programming. RESULTS Patients who consumed the polypill had significantly lower hazard ratios of major cardiovascular events incidence (HR 0.56, 95% CI 0.41-0.78) and cardiovascular mortality (HR 0.41, 95% CI 0.2-0.86) compared to the control group. Polypill showed significantly better results in lowering cardiovascular events in MAFLD patients than in the general population. (p-value for interaction: 0.028). Moreover, comparing those patients who had high adherence to the Polypill, with the control group, further enhanced the results. CONCLUSIONS Major cardiovascular events are prevented in MAFLD patients who consume the Polypill. MAFLD patients benefit from the Polypill more than the general population.

Abstract
BACKGROUND Systemic sclerosis is a multiorgan autoimmune disease that can overlap with other rheumatologic disorders; however, co-occurrence with antineutrophil cytoplasmic antibody-associated vasculitis is rare. CASE PRESENTATION A 39-year-old Persian female patient with systemic sclerosis according to American College of Rheumatology/European League Against Rheumatism 2013 criteria with a disease duration of 6 years was admitted to the hospital due to a rise in creatinine level in July 2021. She had complaints of nasal speech and feeling of nasal perforation. The first symptoms of antineutrophil cytoplasmic antibody-associated vasculitis had started 5 years earlier with palpable purpura in the lower limbs, hemoptysis, and positive perinuclear (p)-antibody-associated vasculitis level (> 300 AU/mL). Still, the diagnosis was not achieved due to the patient's reluctance to undergo a biopsy. She was treated with azathioprine (150 mg/day) and prednisolone (10 mg/day) during the 5-year follow-up. Her renal biopsy results showed cortical renal tissue with a cellular crescent in more than 50% of the specimen, rupture of the Bowman capsule and the glomerular basement membrane, peri-glomerular inflammation, and mild tubular atrophy in microscopic examinations. The immunofluorescence study resulted in a granular pattern of immune deposits along the glomerular basement membrane, mesangial tissue, and tubular basement membranes. CONCLUSION We reported a rare case of comorbid systemic sclerosis and antineutrophil cytoplasmic antibody-associated vasculitis with nasal perforation. Her renal biopsy showed immune deposits along the glomerular basement membrane, mesangial tissue, and tubular basement membranes. Overlapping with other collagen vascular diseases can occur in rheumatology patients with uncommon manifestations. In systemic sclerosis, renal involvement in the form of glomerulonephritis is infrequent, and comorbid systemic lupus erythematosus or antineutrophil cytoplasmic antibody-associated vasculitis should be considered.

Abstract
2D speckle-tracking echocardiography (2D-STE) has been used to assess cardiac recovery during the COVID-19 patient follow-ups within the pandemic. The novel role of STE in predicting adverse outcomes of COVID-19 has received attention due to its high sensitivity in identifying subclinical myocardial dysfunction. We reviewed the studies on using 2D-STE to assess COVID-19 prognosis. A literature search was conducted on PubMed and Scopus for eligible articles, 24 of which discussed using prognostic 2D-STE for COVID-19 patients. 2D-STE predicts cardiovascular impairments more rapidly and precisely than conventional echocardiography. The 2D-STE technique presents an independent prognostic factor in COVID-19 infection. 2D-STE could be considered a time-efficient and accurate risk predictor of all-cause mortality in COVID-19 patients.

Abstract
Saffron crocus is a sterile plant species that propagates vegetatively, and consequently, narrow genetic variation is detected in this species. Besides the narrow genetic variation, there is significant phenotypic variation in different traits in this plant. Here we tested this hypothesis that plant microbiome is a major contributor to the phenotypic variation. We focused our analysis on culturable bacteria that were dominant in saffron fields with high stigma yield compared to the fields with low stigma yield. Following this strategy, four rhizospheric (Cupriavidus metallidurans, Bacillus sp., Solibacillus sp., and Planococcus sp.) and two endophytic bacteria (Serratia oryzae and S. odorifera) were identified. The effects of the bacteria on the growth and development of the model plant Arabidopsis were assessed both in agar plate and pot assays. Results showed that these bacteria influence the vegetative growth and flowering time of Arabidopsis. In the next step, corms of saffron were inoculated with these bacteria and the growth and development of the saffron plants were monitored for five months. Remarkably, inoculation of the bacteria had significant influence on vegetative growth, flowering time, and stigma yield of saffron crocus. Furthermore, one of the bacteria, C. metallidurans, is reported here for the first time as a naturally occurring plant-associated bacteria. Altogether our results suggest that plant microbiome is an important factor in phenotypic variation in saffron crocus.

Abstract
Diagnosis by clinical mycology laboratory plays a critical role in patient care by providing definitive knowledge of the cause of infection and antimicrobial susceptibility data to physicians. Rapid diagnostic methods are likely to improve patient. Aggressive resuscitation bundles, adequate source control, and appropriate antibiotic therapy are cornerstones for success in the treatment of patients. Routine methods for identifying clinical specimen fungal pathogen are based on the cultivation on different media with the subsequent examination of its phenotypic characteristics comprising a combination of microscopic and colony morphologies. As some fungi cannot be readily identified using these methods, molecular diagnostic methods may be required. These methods are fast, but it can cost a lot. Matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) is suitable for high-throughput and rapid diagnostics at low costs. It can be considered an alternative for conventional biochemical and molecular identification systems in a microbiological laboratory. The reliability and accuracy of this method have been scrutinized in many surveys and have been compared with several methods including sequencing and molecular methods. According to these findings, the reliability and accuracy of this method are very high and can be trusted. With all the benefits of this technique, the libraries of MALDI-TOF MS need to be strengthened to enhance its performance. This review provides an overview of the most recent research literature that has investigated the applications and usage of MT-MS to the identification of microorganisms, mycotoxins, antifungal susceptibility examination, and mycobiome research.

Abstract
BACKGROUND AND AIM The association of known cardiovascular risk factors and poor prognosis of coronavirus disease 2019 (COVID-19) has been recently emphasized. Coronary artery calcium (CAC) score is considered to be a risk predictor of cardiovascular events. Therefore, we have conducted a review of literature on the predictive value of CAC score predictive value in COVID-19 outcome. METHOD A search of literature was conducted, aiming for articles published until December 2021 on PubMed and Scopus to identify potentially eligible studies. DISCUSSION A total of 18 articles were reviewed for association between higher CAC score and adverse outcomes in COVID-19. CONCLUSION The coronary calcium score could be considered as a new radiological marker for risk assessment in COVID-19 patients and providing additional information in fields of prognosis and possible cardiovascular complications. High CAC score is associated with higher in-hospital death and adverse clinical outcomes in patients with confirmed COVID-19, which highlights the importance of calcium load testing for hospitalized COVID-19 patients and calls for attention to patients with high CAC scores.

Abstract
Backgrounds The pandemic of COVID-19 has created a global public health crisis. ICU patients with COVID-19 are prone to infections of bacterial and/or fungal origins due to several risk factors. Consequently, the current study was conducted to evaluate the frequency, demographic characteristics, underlying conditions, and etiologic agents of fungal and bacterial co-infections of the respiratory tract among ICU patients with COVID-19 in Iran. Materials and methods From May to October 2020, sputa and endotracheal aspirates were collected from ICU patients hospitalized with COVID-19 who also were suspected of bacterial and/or fungal co-infections according to inclusion criteria. The etiologic agents of bacterial co-infections were identified using the Vitek 2 identification method. For fungal identification, all samples were analyzed by direct microscopy using KOH 10% and culture. Furthermore, all isolates were subjected to sequencing method. Results A total of 73 lung specimens were obtained from patients who met the inclusion criteria. Of these, in 15 cases (20.54%) fungal and/or bacterial co-infections were confirmed. Males were more infected (73.33%) and all of them were between 49 and 79 years. Candida albicans (n = 8, 61.53%) and Klebsiella pneumoniae (n = 5, 38.46%) were the most frequent etiologic agents related to fungal and bacterial co-infections, respectively. Pneumonia (n = 15, 100%) and diabetes mellitus (n = 8, 53.33%) were documented as the most prevalent underlying conditions. In the current study, 3 out of 15 patients (20%) died. Conclusion The frequency of bacterial co-infections of the respiratory tract in ICU patients hospitalized with COVID-19 was relatively high. According to the results, one of the causes of death of these patients could be a secondary infection.

Abstract
Coronavirus disease 19 (Covid-19) has been declared as a pandemic disease since March 2020; causing wide array of signs and symptoms, many of which result in increased mortality rates worldwide. Although it was initially known as an acute respiratory disease, Covid-19 is accompanied with several extrapulmonary manifestations, of which the cardiovascular ones are of major importance. Among other cardiovascular complications of Covid-19, aortic dissection has been a significant yet underrated problem. The pathophysiology of aortic dissection consists of various inflammatory pathways, that could be influenced by Covid-19 infection. We herein have reviewed articles inclusive of aortic dissection concurrent with Covid-19 infection in a systematic manner, along with the probable similarities in pathophysiology of aortic dissection with Covid-19 infection.

Abstract
Introduction Dieulafoy’s lesion, first found by Paul Georges Dieulafoy, is an infrequent but important cause of recurrent upper gastrointestinal bleeding. The bleeding is usually severe, but patients rarely present with chronic, occult gastrointestinal bleeding. Case presentation In this article, we discuss the case of a 68-year-old caucasian man with a history of recurrent hematemesis and chronic anemia with evidence of extravasation of contrast in the lumen of the bowel loop on computed tomography angiography. The patient was taken to the operating room, and a laparotomy procedure was performed. Conclusion Due to the infrequency of Dieulafoy’s lesion compared with other causes of gastrointestinal bleeding, it is often missed in the process of differential diagnosis. In this article, we have demonstrated the importance of this disease and different approaches to the treatment of this lesion, considering the location of the lesion among other factors.

Abstract
AIM This this study aimed to investigate the causes and prognoses of liver re-transplantation in patients referred to Imam Khomeini Hospital Liver Transplantation Center. BACKGROUND Organ shortage is a major problem in the world, a high demand for liver transplantation has exacerbated this problem. Thus, providing more information on the causes of liver re-transplantation, its prognosis, and other issues related to this procedure is of great importance. METHODS This study was conducted in 2018 as a historical cohort. In this study, the records of liver transplantation patients at Imam Khomeini Hospital Liver Transplantation Center between 2000 and 2016 were studied, and data was extracted from the records of patients undergoing liver transplantation. Patient data was entered into SPSS 20 software and analyzed. RESULTS In this study, 1030 patients with a mean age of 43.15 ± 14.57 years were studied. There were 426 women (41.4%) and 604 men (58.6%). The number of primary transplants was 966 with a mean age of 43.19 ± 14.72, and the number of re-transplants was 64 with a mean age of 42.56 ± 12.82. Significant differences were found between the two groups in terms of MELD and CHILD scores, cold ischemic time, total and direct bilirubin levels, liver function factors (ALT, AST, and alkaline phosphatase), hemoglobin, and WBC. There was no significant difference between the two groups in terms of age, sex, or platelets (> 0.05). The mortality rate was 241 (23.39%) in all patients and the mortality rate was 206 (21.32%) and in liver transplant patients was 35 (54.68%). The mortality rate in the transplant group was statistically higher (p<0.001). Secondary was primary non-functional graft (PNF) (37.5%) with 1-, 3, and 5-year survival rates of 82%, 81%, and 70% in primary group and 59%, 43% and 32% in re-transplantation, respectively. There was a significant difference in survival between the two groups (p <0.05). Hemoglobin and alkaline phosphatase were predictors of survival rates in transplant patients. CONCLUSION The results of this study showed that the survival rate of re-transplant patients was significantly lower than that of primary transplant patients, and the mortality rate in re-transplant patients was significantly higher.
