Tacrolimus (FK506) is the most widely used anti-rejection drug in kidney transplantation, especially its extended release Tacrolimus formulation (ER-Tac, Advagraf), which is used when target blood levels can be difficult to reach in high metabolizer patients. In this retrospective monocentric study, we analyzed the effect of a switch from ER-Tac to LifeCycle Pharma Tacrolimus (LPCT, Envarsus) on the dose/level ratio of FK506 in high metabolizer patients that cannot achieve target blood levels in the first 6 months after transplantation. We observed a statistically significant improvement in the level to dose ratio after the switch. Renal function remained stable. We also observed a reduction in the development of tremors. Our data suggest that LPCT can be used in a safer way in high metabolizer kidney transplant recipients.

Hepatitis C virus (HCV) causes increased mortality and morbidity in kidney transplant patients. Interferon-based therapies are poorly tolerated and involve the risk of rejection. The new direct-acting antiviral drugs (DAAs) have revolutionized the treatment of HCV infection in transplant patients. This observational study evaluates changes in immunosuppressive therapy during treatment with DAA in renal transplant recipients. In our transplant center, we selected seven HCV-positive patients at the time of transplantation , four men and three women, with an average age of 61 ± 7 years, in therapy with DAA. The dose and the blood levels of the immunosuppressive drugs were evaluated at the beginning and end of antiviral therapy, together with creatinine and proteinuria. Viremia was negativized in all patients within the initial 8 weeks of therapy. Currently, the number of patients is too limited to perform a sta-tistical analysis and obtain significant results. In one patient, the dose of Cyclosporine was lowered to 10 mg, while for the remaining patients it was not necessary to change the dose of immunosuppressive drugs. DAAs give encouraging results in the eradication of HCV in renal transplant recipients, although they are associated with potential adverse drug interactions. The preliminary data of our study suggest that it is not necessary to change the dose of immunosuppressive drugs during therapy and that creatinine and proteinuria remain stationary. We will achieve more significant results in the future, adding more patients to our study. However, further randomized trials are necessary to confirm the safety of DAAs.

Background: In recent years, the rise of workplace racial discrimination and microaggressions has decreased the efficiency and productivity of organizations and institutions, and realization of organizational goals globally. Accordingly, it was decided to conduct a systematic review and meta-analysis in the present study with the aim of investigating the prevalence of microaggression and racial discrimination in the workplace. Methods: The PubMed, Scopus, Web of Science, ScienceDirect and Google Scholar databases were systematically searched for studies that had reported the effects of work stress among managers. The search did include a lower time limit and was conducted in June 2023. The heterogeneity of the studies was investigated using the I2 index, and accordingly random effects method was adopted for meta-analysis. Data analysis was conducted with the Comprehensive Meta-Analysis (v.2) software. Results: In the review of seven studies with a sample size of 2998 people, the overall prevalence of microaggression and racial discrimination in the workplace was found to be 73.6% and 18.8%, respectively. Publication bias within the selected studies was examined with the Egger's test, which indicated the absence of publication bias for the pooled prevalence of workplace microaggression (p: 0.264) and for the pooled prevalence of workplace racial discrimination (p: 0.061). Conclusion: The results obtained from this report indicate the high impact of micro-aggression and racial discrimination in the workplace. Considering the negative effects of such behaviours, the findings from this study will be helpful to managers and health policymakers.

Abstract Background Isolated pulmonary valve endocarditis (IPE) accounts for less than 2% of all infective endocarditis patients. It is commonly associated with several predisposing factors, including intravenous drug use (IVDU) and congenital heart disease. The most common causative pathogens of IPE are Staphylococcus aureus and Streptococcus viridans. We report a Down’s syndrome patient with IPE and with no standard risk factors caused by the rare pathogen Acinetobacter spp. This led to respiratory failure and systemic infection due to septic pulmonary emboli. Early elective surgery was decided upon as the patient was no longer responding to medical therapy, and his clinical condition was worsening over time. Case presentation A 15-year-old male with Down syndrome and no underlying heart defect presented with a 3-month history of episodic fever, nausea, vomiting, and diarrhea. Transthoracic echocardiography (TTE) revealed large vegetation on the pulmonary valve leaflet, another mobile mass at the pulmonary artery bifurcation, and severe pulmonary regurgitation. Serial blood cultures isolated Acinetobacter spp. Despite initial antibiotic therapy, the patient continued to have sepsis, unresolved vegetations, and developed life-threatening complications and respiratory distress, which convinced us to perform a pulmonary valve replacement surgery with a homograft. After surgery, the patient recovered and was discharged on the ninth postoperative day (POD). Conclusion This report highlights IPE’s diagnostic and therapeutic challenges, alongside the importance of a comprehensive cardiopulmonary workup in patients with unexplained fever, sepsis, and pulmonary symptoms, even without typical risk factors. Based on the patient’s aggravating condition despite medical treatment, early surgical intervention and pulmonary valve replacement were deemed crucial. However, there still needs to be a definitive guideline on when and how surgery should be performed in patients with complicated IPE, especially in pediatric patients.

End-stage renal disease (ESRD) is a progressive chronic condition that is strongly associated with cardiovascular mortality. ESRD patients usually benefit significantly from kidney transplantation. Pulmonary hypertension (PH) is a common finding in ESRD patients that adversely affects their survival. It has also been associated with adverse increased mortality and morbidity following kidney transplantation. However, PH has also been thought to improve following kidney transplantation. The exact underlying pathophysiology of PH in ESRD patients is unknown. However, it has been believed to be multifactorial, involving endothelial dysfunction, volume overload, and arteriovenous fistula. Management of PH in kidney transplant candidates and ESRD patients is remarkably understudied. Several treatment options are available for the treatment of PH. However, studies conducted on treating PH in ESRD patients are scarce. There is an increased need for studies on ESRD patients with PH.

Abstract Background Obesity is a known risk factor for atherosclerosis and cardiac disease. Hypothesis This study evaluated the effect of significant weight loss following bariatric surgery on myocardial deformation indices and right ventricular size (RV). This was a prospective cohort study. Morbid obese patients scheduled for bariatric surgery from July 2017 to February 2018 at Firoozgar Hospital were included in our study and referred for transthoracic echocardiography at Rajaie Cardiovascular Medical and Research Center. Results Thirty-four patients entered the study. The absolute value of global longitudinal strain (GLS) at baseline, 3, and 6 months after surgery was 17.42 ± 2.94%, 18.24 ± 3.09%, and 19.52 ± 2.78%, respectively, with a statistically significant difference from baseline to after six months (P value

Abstract Background Fungal endocarditis is a rare but serious condition associated with high mortality rates. Various predisposing factors contribute to its occurrence, such as underlying cardiac abnormalities, cardiac surgeries, prosthetic cardiac devices, and central venous catheters. Diagnosing fungal endocarditis, particularly Aspergillus, poses challenges, often complicated by negative blood cultures. Case presentation This report details a case of extensive ascending aorta involvement in Aspergillus endocarditis (AE) in a 24-year-old man with a history of bioprosthesis aortic valve replacement (AVR). Three months post-AVR, he presented with pericardial effusion and aortic rupture, leading to a redo biological valved conduit aortic root replacement (Bentall surgery). Despite the intervention, the tubular graft exhibited extensive Aspergillus involvement, resulting in graft disruption and significant peri-aortic infection. A second redo procedure involving aortic homograft root replacement was performed. Unfortunately, the patient succumbed two days after the surgery. Conclusion A combined approach of medical and surgical therapies is recommended to manage fungal endocarditis. Despite efforts, the mortality rate associated with Aspergillus endocarditis remains unacceptably high, with no significant difference observed between combination therapy and antifungal treatment alone. Further research is essential to explore novel therapeutic strategies and improve outcomes for patients with this challenging condition.

Abstract Background Mechanical heart valve replacement is a standard treatment for severe valvular disorders. The use of mono-leaflet valves has decreased recently. Recognizing the echocardiographic features of mono-leaflet and bileaflet valves is crucial for accurate complication diagnosis and proper management. Case Presentation A 65-year-old female with mono-leaflet mitral and bileaflet tricuspid valves underwent an echocardiographic assessment. This simple educational case provides a unique opportunity to compare the echocardiographic features of these valves within a single patient. Conclusion There is a crucial need for clinicians, particularly those in training, to differentiate between mono-leaflet and bileaflet mechanical heart valves adeptly. With mono-leaflet valves decreasing in prevalence, proficiency in recognizing the echocardiographic nuances of each type is imperative. Failure to do so may result in misdiagnoses and inappropriate management. This underscores the significance of continuous education and vigilance in echocardiographic assessments to ensure optimal patient care.

Key Clinical Message Rudimentary left atrial appendage (LAA) is an extremely rare condition with an unclear association with cerebrovascular events. This case report discusses a patient with an unexplained cerebrovascular accident (CVA), where the diagnosis of rudimentary LAA was made using transesophageal echocardiography (TEE) and subsequently confirmed by computed tomography angiography (CTA). Abstract Rudimentary left atrial appendage (LAA) is extremely rare. This report presents the case of a 50‐year‐old woman who experienced a cerebrovascular accident (CVA) and was found to have a rudimentary LAA. The patient had a history of diabetes mellitus (DM), hypertension, and dyslipidemia. An electrocardiogram (ECG) showed sinus rhythm, and Holter monitoring did not detect any atrial fibrillation (AF). Transesophageal echocardiography (TEE) and computed tomography angiography (CTA) were performed to identify the source of cardiac emboli, revealing a rudimentary LAA with no thrombus present.

This paper aims to contribute reliable information to promote the pharmacological utilization of Papaver bracteatum by analyzing its wild population in Iran. For this purpose, 27 Iranian poppy specimens from 7 provinces of Iran were analyzed. The highest thebaine concentrations were detected in the capsules, whereas they were relatively lower in the flowering stems. Maximal concentration (more than 53 mg/g d.w.) was present in the P. bracteatum plant capsules growing in the Zanus region of Mazandaran province. Surprisingly, the thebaine concentration varies drastically excessively among the tested specimens, ranging from 5 to more than 53 mg/g d.w. Up to now, it is not known whether these drastic differences are due to clonal variations or the differences in the growth conditions, e.g., due to different stress levels of the plants. There is no doubt that the Iranian poppy represents an important alternative source for thebaine, yet, further studies and research are required to promote the farming of this auspicious pharmaceutical plant. In this context, it is of special interest to elucidate the effects of potential genotypes, the impact of the growing conditions as well as seasonal effects.

Abstract Background Echocardiographic estimation of left ventricular filling pressure in heart transplant (HTx) recipients is challenging. The ability of echocardiography to detect elevated left ventricular end-diastolic pressure (LVEDP) in HTx patients was assessed in this study. Results This descriptive cross-sectional study included 39 HTx recipients who were candidates for endomyocardial biopsy as a part of their routine post-transplantation surveillance. Doppler transthoracic echocardiography was done before the procedure, and left heart catheterization was done during the endomyocardial biopsy. Thirty-nine patients (15 female, 24 male), with a mean age of 39.6 years (range 13–70), were enrolled. A strong relation was observed between lateral E/e′ and LVEDP (R = 0.64, P value

Abstract Background Cardiac involvement is common in end-stage renal disease patients. The presenting study aimed to evaluate the global and segmental longitudinal strain in patients with advanced uremic cardiomyopathy (AUCM) and compare it to dilated cardiomyopathy (DCM). Results The mean global longitudinal strain (GLS) was significantly lower in AUCM (P value = 0.045). Comparing segmental strain showed a lower strain in mid inferoseptal (P value = 0.048), base and mid anterolateral (P value = 0.026, 0.001 respectively), base and mid anteroseptal (P value = 0.005, 0.009 respectively), base and mid inferior (P value = 0.015, 0.034 respectively) and mid anterior (P value = 0.015) in patients with AUCM compared with DCM. In both groups, the segmental strain increased from base to apex. Conclusions Segmental and GLSs in advanced uremic cardiomyopathy were significantly lower than those of dilated cardiomyopathy. In both groups, the segmental strain increased from base to apex.

Abstract Background Preoperative cardiovascular risk assessment is one of the main principles before noncardiac surgeries. Cardiac stress imaging, such as myocardial perfusion scan (MPS), is a proposed cardiovascular risk evaluation method according to the latest guidelines. Yet, its efficacy, along with the cost-effectiveness of the method, has been questioned in previous studies. Our study aims to evaluate the utility of N-terminal pro-b-type natriuretic peptide (NT-proBNP) level measurement in predicting postoperative cardiovascular complications in candidates who have undergone an MPS before surgery and compare the results. Methods A cohort of 80 patients with a revised cardiac risk index score of one or more who were scheduled for moderate to high-risk noncardiac surgeries and met the criteria to undergo an MPS for risk assessment were included in the study. All of them underwent an MPS one week before surgery. Their preoperative NT-proBNP, troponin levels, and electrocardiograms were obtained one day before surgery and again on day three postoperative. The predictive efficacy of NT-proBNP levels and MPS were compared. Results Seventy-eight patients underwent surgery, three of which exhibited a rise in troponin level, six showed changes on electrocardiogram, and pulmonary edema was detected in one, three days after surgery. There was no mortality in our patients. The sensitivity and specificity of the MPS for predicting postoperative cardiovascular complications were 100% and 66%, respectively. MPS also had a positive predictive value of 20% and a negative predictive value of 100% in our study. A 332.5 pg/ml cut-off value for NT-proBNP level yielded a sensitivity of 100%, specificity of 79.2%, positive predictive value of 40%, and negative predictive value of 100%. Conclusions Our study reveals the incremental specificity and positive predictive value of NT-proBNP level measurement in preoperative cardiovascular risk evaluation compared to MPS. Given the low feasibility, high costs, and disappointing predictive value of MPS, preoperative NT-proBNP level assessment can be substituted. This method can assist anesthesiologists and surgeons with precisely detecting at-risk patients resulting in taking proper measures to reduce the morbidity and mortality of the proposed patients before and during surgeries.

Objective(s): The prevalence of coronary artery disease (CAD) is high in patients with epilepsy using antiepileptic drugs (AED). Epilepsy, AED, or the type and duration of AED use , may contribute to higher CAD risk.In this study, myocardial perfusion imaging (MPI) was compared between patients using carbamazepine and valproate.Method: Out of 73 patients receiving carbamazepine or valproate monotherapy for more than 2 years, visited at a tertiary referral clinic, 32 patients participated in a 2-day stress and rest phases MPI. For each phase, 15-25 mCi 99mTc-MIBI was injected, at peak exercise or by pharmacologic stimulation for the stress phase. SPECT with cardiac gating was done by a dual-head gamma camera and processed and quantified. Scans with at least one definite reversible hypo-perfusion segment were considered abnormal.Results: Seventeen patients received carbamazepine monotherapy and 15 valproates. Age and duration of AED use were similar between the groups. Two scans were abnormal (6.3%) both in valproate group (13.3%). Duration of AED use was higher in patients with abnormal scans. In patients receiving monotherapy >2 years, the frequency of abnormal MPI was similar between groups (P-value=0.12). In patients receiving monotherapy > 5 years, prevalence of abnormal MPI was higher in the valproate group (28.6% vs. 0.0%; P-value=0.042). Considering valproate subgroup, ischemic patients had higher duration of AED use, comparing with the normal patients (17.0±4.2 vs. 6.4±4.8, P-value=0.014).Conclusion: MPIs were abnormal in patients receiving valproate after 5 years compared to patients receiving carbamazepine. Long-term valproate use may increase the risk of CAD.

Abstract Background In acute myocardial infarction (AMI), timely recognition of symptoms and early hospital presentation positively affect patient morbidity and mortality. Due to the high burden of ischemic heart disease in Iran, this study aimed to identify factors affecting the level of knowledge, responses at the time of AMI onset, and sources of health information among the Iranian population. Method This cross-sectional study was conducted in three tertiary hospitals in Tehran, Iran. An expert-validated questionnaire was used to obtain data. A total of 400 individuals were enrolled. Result Among the respondents, 285 people(71.3%) considered “chest pain or discomfort,” and 251 (62.7%) regarded “pain or discomfort in the arm or shoulder” as MI symptoms. Approximately 288 (72.0%) respondents had poor knowledge of the AMI symptoms. Knowledge of symptoms was higher among those with higher levels of education, those with medical-associated jobs, and those who resided in the capital areas. Major risk factors identified by the participants were: anxiety (340)(85.0%), obesity (327)(81.8%), an unhealthy diet (325)(81.3%), and the presence of high LDL levels (258)(64.5%) and Diabetes Mellitus (164)(41.0%) were less appreciated. Calling an ambulance (286)(71.5%) was the most common treatment-seeking behavior in the case of a suspected heart attack. Conclusion It is vital to educate the general population about AMI symptoms, particularly those with comorbidities at the greatest risk for an AMI episode.

Abstract Background Nearly half of the patients with hypereosinophilic syndrome (HES) have cardiovascular involvement, a major cause of mortality. COVID-19 infection can lead to cardiac involvement, negatively impacting the clinical course and prognosis. We reported two patients with HES complicated by COVID-19, with cardiac involvement and valve replacement. Case presentation Our first patient was a 27-year-old woman admitted due to dyspnea and signs of heart failure. She had severe mitral stenosis and mitral regurgitation on the echocardiogram. Corticosteroid therapy improved her symptoms initially, but she deteriorated following a positive COVID-19 test. A repeated echocardiogram showed right ventricular failure, severe mitral regurgitation, and torrential tricuspid regurgitation and, she underwent mitral and tricuspid valve replacement. Our second patient was a 43-year-old man with HES resulted in severe tricuspid stenosis, which was improved with corticosteroid treatment. He underwent tricuspid valve replacement due to severe valvular regurgitation. He was admitted again following tricuspid prosthetic mechanical valve thrombosis. Initial workups revealed lung involvement in favor of COVID-19 infection, and his PCR test was positive. Conclusion COVID-19 infection can change the clinical course of HES. It may result in a heart failure exacerbation due to myocardial injury and an increased risk of thrombosis in prosthetic valves or native vessels due to hypercoagulability.

Key Clinical Message Cardiac hydatidosis is a relatively rare complication of echinococcosis. Understanding the atypical manifestations, potential associated risk factors, and epidemiology leads to optimal and timely management. Abstract Cardiac hydatidosis is a relatively rare complication of echinococcosis, with a potentially life‐threatening condition. Here, we reported a large interventricular septal hydatid cyst bulging in the left ventricle accompanied by a huge cervical lamp with recurrent hepatic cysts that underwent cardiac surgery to excise the cyst uneventfully.

Abstract Atrial fibrillation is one of the major predisposing factors in developing left atrial thrombosis, leading to morbidity and mortality. Echocardiography plays a paramount role in this condition's detection and subsequent treatment.

Abstract Congenital heart disease is a risk factor for infective endocarditis (IE). Ventricular septal defects and ventricular outflow tract obstructions are this population's most common causes of endocarditis. We present a patient diagnosed with leukocytoclastic vasculitis, renal, and pulmonary involvement with right‐sided IE as an etiology for vasculitis.

Solid-organ transplantation recipients were assumed highly vulnerable to coronavirus disease 2019 (COVID-19). However, the results of previous studies in patients with orthotopic heart transplantation (OHT) under immunosuppressive therapy are contradictory. Therefore, we aimed to assess the prevalence of COVID-19 infection and associated risk factors, along with the six-month outcomes in COVID-19 positive OHT patients. This single-center telephone-based survey was conducted on OHT patients. Using a detailed questionnaire, exposure to COVID-19, related symptoms, and preventive self-care measures were collected. Outcomes of COVID-19-positive patients were reassessed using another survey six months later. 118 OHT patients (male: n=87, 73.7%) were included with a mean age of 45.3±13.1 years. Sixteen patients (13.5%) reported one or more symptoms compatible with COVID-19, of whom 12 (10.2%) tested positive. Our results indicated no statistically significant association between COVID-19 and comorbidities. Poor adherence to self-care measures and contact with positive index cases were both significantly associated with COVID-19 infection (P

Background: This study aimed to investigate and compare the characteristics of abdominal pain after bariatric surgery with two techniques of Laparoscopic One-Anastomosis Gastric Bypass (LOAGB) and Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) in patients with morbid obesity. Methods: This prospective descriptive-analytical study was conducted on 114 patients who were candidates for bariatric surgery. Patients were entered to study in one of two groups of LOAGB and LRYGB by convenient and continuous sampling. The characteristics of abdominal pain of patients were investigated and compared at certain periods (24 and 48 hours and 10, 20, 30, and 90 days after surgery) using McGill Pain Questionnaire. Findings: The frequency of severe abdominal pain in the LOAGB group within 48 hours after surgery was significantly higher than the LRYGB group (P < 0.05). The highest abdominal pain distribution at the first 5 time periods in the two groups was in the left lower quadrant of the abdomen. The frequency of description of ambiguous pain within 48 hours and 10 days in the LOAGB group was significantly higher than LRYGB. The frequency of pattern of periodical (intermittent) pain at the periods of 48 hours and 10 and 20 days after surgery in the LOAGB group was significantly higher than LRYGB. Conclusion: The results of this study showed that there was no significant difference in the frequency of abdominal pain and its distribution between LOAGB and LRYGB groups. However, the definitive decision to choose a bariatric surgery technique for lower abdominal pain requires further study.

Background and Aim: Cardiovascular diseases and medication errors are among the leading causes of morbidity and mortality around the world. Electronic prescribing and Medication Administration(ePMA) systems can prevent medication errors to some extent. This study aimed to determine the information requirements of ePMA systems. Materials and Methods: This descriptive study was conducted in Imam Khomeini Hospital of Tehran and School of Allied Medical Sciences affiliated to Tehran University of Medical Sciences (TUMS) in the summer of 2019 in two phases: literature review and survey-based questionnaire. Information items obtained from reviewing the texts of 100 articles were organized in three questionnaires. In the survey phase, questionnaires were distributed among physicians, nurses, and the experts of health information management(HIM) and medical informatics, using census sampling method. The reliability of the questionnaires was measured using Cronbachchr('39')s coefficient alpha. Statistical analysis was done using SPSS. Results: The findings showed that based on specialists’ point of view, patientschr('39') demographic information items and unique identifiers gained the highest average, above 4.7. Physicians agreed most with clinical information, including medication history and generic names. From the nurses’ point of view, the information items of the patients’ problems and the procedures performed and the types of drug doses obtained a complete average of 5. Conclusion: The need for information items varies among different users of ePMA systems, but there may be items that are common for them. Future studies should further investigate financial and pharmaceutical information requirements based on the perspectives of other hospital pharmacy and accounting staff.

Pre-transplant kidney biopsy is routinely used to decide whether kidneys from marginal donors should be transplanted as single or double trans-plantation. This is a 5-year extension of the follow-up of a previous study. In that study, graft outcomes were compared retrospectively between a group of 44 recipients of a single kidney graft from an extended criteria donor and a Karpinski histological score of 3 or less, and another group of 56 recipients of a single transplant with a Karpinski histological score of 4 or 5. After 5 years of transplantation, there was no difference between the two groups in terms of recipient’s serum creatinine levels (1.8 ± 0.5 vs 1.9 ± 0.6 mg/dL, P = 0.5), creatinine clearance (53 ± 23 vs 49 ± 27.0 mL/min, P = 0.6), or the rates of graft loss (41% vs 49%,P = 0.5). Therefore, the choice between single and double transplant should not be made only on the basis of histological score but should be done together with the evaluation of donor’s clinical parameters, especially the renal function.

Granulomatosis with polyangiitis (GPA), necrotizing vasculitis of small and medium-sized vessels, is traditionally believed to mainly affect respiratory tract with additional focal kidney involvements as its primary manifestations with a relatively rare annual incidence rate of 20-50 cases per million. Six percent of the affected cases have cardiac involvements; among which, aneurysms comprise the lowest penetrance. By this paper, we aim to cast light on clinical diagnostic and treatment methods of a rare case presentation, a 10-year-old male GPA patient, diagnosed with massive thrombosis at his coronary artery aneurysm. GPA should be considered as differential diagnosis of prolong fever and coronary aneurysms in adolescents.

Purpose The purpose of this study was to investigate the effects of a role-playing training program conducted among operating room nursing students on empathetic communication with patients through measurements of empathy scores. Methods This study was carried out among 77 operating room nursing students from the first to the fourth years studying at the School of Nursing and Midwifery of Isfahan University of Medical Sciences in the academic year 2017–2018. The intervention administered to the experimental group included a 12-hour training program on expressing empathy to patients that incorporated roleplaying. The Jefferson Scale of Empathy-Health Profession Student version was completed by the participants before, immediately after, and 1 month after the intervention. A comparative analysis of these 3 time points was conducted. Results No significant difference was found in the total pre-intervention mean empathy scores before the intervention between the control group and the experimental group (P= 0.50). However, the total mean empathy scores in the experimental group immediately after and 1 month after the intervention were higher than those in the control group (P< 0.001). Conclusion Empathy training through a role-playing technique was effective at improving the empathy scores of operating room nursing students, and this finding also underscores the fact that empathy can be promoted by education. Changing the educational curriculum of operating room nursing students is suggested in order to familiarize them with the concept of empathy in the operating room.

In recent decades, the policies of financial and trade liberalization have been considered in most of the world countries, and there are different experiences in this regard. Therefore, this study will review the effects of financial and trade liberalization on the production volatility in Iranian economy (with and without oil sector) by using Autoregressive Distributed Lag (ARDL) model for the period of 1960 to 2007. The results show that in the model that includes oil sector, trade liberalization has positive and significant effect, but financial liberalization has negative and non-significant effect on production volatility. In the model without oil, financial and trade liberalization policies both have a positive and significant effect on production volatility. In addition, the long-term relationships between the variables are approved. The value of error correction coefficient is estimated to be -0.49, which shows the amount of adjustment toward equilibrium values in the long-run. The structural stability tests for the model's strength are acceptable for the period of study.

In this work, sequence-related amplified polymorphism (SRAP) marker was employed to assess the genetic diversity and genetic similarity relationships among14 species of Alcea collected from northwest of Iran. Seventeen SRAP primer combinations generated 104 fragments, of which 97 (93%) were polymorphic, with an average of 5.7 polymorphic fragments per primer. Percentage of polymorphism ranged from 50% (ME2-EM6) to a maximum of 100%, and mean polymorphism information content value obtained was 0.3. The lowest genetic similarity (0.17) was observed between A. sophiae and A. flavovirens, while the highest was found between A. digitata and A. longipedicellata (0.68). Two main clusters were detected using UPGMA, which did not correspond to geographical origin of the species. The study indicates that SRAP markers could be good candidates for assessing genetic variation in Alcea.

Objective:To investigate the hematologic indices of mothers in non-immune hydrops fetalis pregnancies and identify the possible causative role of Alpha-Thalassemia among them. Material and methods: From 2005 to 2007, 11386 hydrops fetalis cases in three major obstetric hospitals affiliated to Tehran University of Medical Sciences were recorded. Indirect coombs test and hematologic indices of maternal samples were assessed. Results: Among 11386 deliveries, 67 hydrops fetalis cases were detected. Forty-one (62%) cases were immune type and 26 (38%) cases were non-immunehydrops. All the mothers had MCV more than 80 fl and 25 mothers had MCH more than 27 pg, so none of themhad Alpha-Thalassemia carrier criteria. Conclusion: Alpha- Thalassemia is not the major cause of hydrops fetalis in this study and cost-effectiveness of population scaled biochemical and/or molecular screening programs of α-globin gene mutations in Tehran population is under question.

Abstract Background Osteoporosis is one of the most common bone system diseases that is associated with an increased risk of bone fractures and causes many complications for patients. With age, the prevalence of this disease increases so that it has become a serious problem among the elders. In this study, the prevalence of osteoporosis among elders around the world is examined to gain an understanding of its prevalence pattern. Methods In this systematic review and meta-analysis, articles that have focused on prevalence of osteoporosis in the world’s elders were searched with these key words, such as Prevalence, Osteoporosis, Elders, Older adult in the Science Direct, Embase, Scopus, PubMed, Web of Science (WoS) databases and Google Scholar search engine, and extracted without time limit until March 2020 and transferred to information management software (EndNote). Then, duplicate studies were eliminated and the remaining studies were evaluated in terms of screening, competence and qualitative evaluation based on inclusion and exclusion criteria. Data analysis was performed with Comprehensive Meta-Analysis software (Version 2) and Begg and Mazumdar test was used to check the publication bias and I2 test was used to check the heterogeneity. Results In a review of 40 studies (31 studies related to Asia, 5 studies related to Europe and 4 studies related to America) with a total sample size of 79,127 people, the prevalence of osteoporosis in the elders of the world; 21.7% (95% confidence interval: 18.8–25%) and the overall prevalence of osteoporosis in older men and women in the world, 35.3% (95% confidence interval: 27.9–43.4%), 12.5% (95% confidence interval: 9.3–16.7%) was reported. Also, the highest prevalence of osteoporosis in the elders was reported in Asia with; 24.3% (95% confidence interval: 20.9–28.1%). Conclusion The results of the present study showed that the prevalence of osteoporosis in the elders and especially elders' women is very high. Osteoporosis was once thought to be an inseparable part of elders’ lives. Nowadays, Osteoporosis can be prevented due to significant scientific advances in its causes, diagnosis, and treatment. Regarding the growing number of elderly people in the world, it is necessary for health policy-makers to think of measures to prevent and treat osteoporosis among the elders.

Background & Aims: Surgical site infection (SSI) is a common postoperative complication. The observance of the aseptic technique is an effective measure to prevent SSI. The knowledge and performance of surgical technicians and technologists play a pivotal role in the proper implementation of this technique. The present study aimed to compare the knowledge and performance of surgical technicians and technologists regarding the observance of the aseptic technique. Materials & Methods: This cross-sectional, comparative study was conducted during 2017-2018 on 235 surgical technicians and technologists in eight teaching hospitals in Isfahan, Iran. The participants were selected via stratified random sampling. Data were collected using a researcher-made questionnaire for the measurement of knowledge, which was completed by the participants. In addition, a researcher-made checklist was completed by the researcher after observing the performance of the participants in three surgical procedures. Data analysis was performed in SPSS version 22.0 using descriptive and analytical statistics. Results: The mean score of the knowledge of surgical technicians and technologists was favorable, while their mean score of performance was average. The mean score of knowledge (P=0.047) and performance (P=0.01) was significantly higher in the surgical technologists compared to the surgical technicians. Moreover, a direct correlation was observed between the scores of knowledge and performance in both surgical technicians (P=0.027) and surgical technologists (P=0.032). Conclusion: According to the results, improving the knowledge of surgical technicians and technologists regarding the aseptic technique could enhance their performance in this regard. Therefore, the findings of this study could lay the groundwork for the proper supervision of the performance of healthcare providers in order to harmonize their knowledge and performance. Furthermore, considering the higher scores of knowledge in surgical technologists compared to the technicians, it is advisable that the latter be encouraged to continue their education. The implementation of effective training programs should also be considered in order to improve the performance of operating room personnel.

Breast cancer is the most common cancer among the female population, and its prevalence is increasing worldwide. Trastuzumab (Herceptin) therapy improves prognosis in HER2 positive patients, but Heart Failure (HF) is one of its known complications. In this study, we aimed to assess the potential benefits of prophylactic carvedilol therapy in patients receiving Herceptin. Sixty five patients with HER2 positive breast cancer were enrolled in the study. All of the patients received Herceptin. Twenty seven patients also received carvedilol 6.25 mg twice daily, and 38 patients had usual care. Echocardiography was performed at baseline, and after three months in both groups and changes in cardiac function, parameters were compared between two groups. After 3 months, LA volume index (P=0.012), TAPSE (P=0.009), Tei index (P=0.015) and Lateral Longitudinal Strain (P=0.024) were significantly better in patients receiving carvedilol. Carvedilol can be effective in the prevention of systolic and diastolic dysfunction following Herceptin therapy.

Abstract Background Antineutrophil cytoplasmic antibody associated vasculitis (AAV) is a group of diseases associated in most cases with the presence of anti-neutrophil cytoplasmic antibodies (ANCAs). Rituximab- based remission induction has been proven effective in ANCA associated vasculitis but scarce data exist in forms with severe renal involvement. In this case series, we report the outcomes in patients with de novo or recurrent MPO-AAV and severe renal involvement treated with rituximab without cyclophosphamide (CYC). Methods In this single centre retrospective study, we analysed patients with a clinical diagnosis of de novo or recurrent AAV who met the following criteria: detection of P-ANCA, creatinine clearance lower than 30 ml/min, induction of remission therapy with rituximab without concomitant CYC and a follow up period of at least 6 months. The primary outcomes were complete remission after induction therapy, renal function recovery and mortality after the induction treatment. Results Eight patients met the inclusion criteria. The M:F ratio was 1:7, the average age was 54 years old and the median follow up was 10 months (7–72); in 2 patients there was a MPA renal limited vasculitis. A renal biopsy was performed in 7 patients. The median BVAS score at rituximab induction was 14(range 6–21). Two patients required haemodialysis before the induction treatment. Four patients developed end stage renal disease (ESRD) that required haemodialysis. These data show a remission of the disease, associated with a stabilization of the kidney function in 50% of patients. In 3 patients who did not show a response, there was also no response to CYC. Conclusions This study shows a partial efficacy of rituximab in renal function recovery and a low risk of infectious complications in patients with MPO vasculitis with severe renal involvement, in particular in the short term. The optimal treatment in this subgroup of patients still has to be established because data are lacking.

Abstract Background The X chromosome has historically been one of the most thoroughly investigated chromosomes regarding intellectual disability (ID), whose etiology is attributed to many factors including copy number variations (CNVs). Duplications of the long arm of the X chromosome have been reported in patients with ID, short stature, facial anomalies, and in many cases hypoplastic genitalia and/or behavioral abnormalities. Methods Here, we report on a large Iranian family with X‐linked ID caused by a duplication on the X chromosome identified by whole genome sequencing in combination with linkage analysis. Results Seven affected males in different branches of the family presented with ID, short stature, seizures, facial anomalies, behavioral abnormalities (aggressiveness, self‐injury, anxiety, impaired social interactions, and shyness), speech impairment, and micropenis. The duplication of the region Xq13.2q13.3, which is ~1.8 Mb in size, includes seven protein‐coding OMIM genes. Three of these genes, namely SLC16A2, RLIM, and NEXMIF, if impaired, can lead to syndromes presenting with ID. Of note, this duplicated region was located within a linkage interval with a LOD score >3. Conclusion Our report indicates that CNVs should be considered in multi‐affected families where no candidate gene defect has been identified in sequencing data analysis.

Background & Aim: Documentation of cares is one of the responsibilities of operating room nurses. One of the possible patient damages caused during surgery is use of electrocautery and tourniquet devices. Despite the need for recording the performance of these devices, there is no specific part on surgery checklists dedicated to this issue. Therefore, this study aimed to change the safe surgery checklist through documenting the application of electrocautery and tourniquet devices. Materials & Methods: This action research was conducted on 30 operating room nurses in Isfahan, Iran in 2017. The solution of choice was adding a researcher-made checklist to the operating room files in order to document the use of electrocautery and tourniquet devices for three months. In addition, a researcher-made survey on the status of operating room file documentation was filled by the subjects before and after the intervention. Moreover, data analysis was performed in SPSS version 22 using descriptive and analytical statistics. Results: In this research, 28 out of 30 participants had a mean work experience of 11.87±8.30 years in operating rooms. Furthermore, there was a significantly higher frequency of positive response to the question of “Do you think that the checklist is useful?” after the intervention, compared to before the intervention (P

To present a multiple-instructor, active-learning strategy in the undergraduate medical curriculum. This educational research is a descriptive one. Shared teaching sessions, were designed for undergraduate medical students in six organ-system based courses. Sessions that involved in-class discussions of integrated clinical cases were designed implemented and moderated by at least 3 faculties (clinicians and basic scientists). The participants in this study include the basic sciences medical students of The Tehran University of Medical Sciences. Students’ reactions were assessed using an immediate post-session evaluation form on a 5-point Likert scale. Six two-hour sessions for 2 cohorts of students, 2013 and 2014 medical students during their two first years of study were implemented from April 2014 to March 2015. 17 faculty members participated in the program, 21 cases were designed, and participation average was 60 % at 6 sessions. Students were highly appreciative of this strategy. The majority of students in each course strongly agreed that this learning practice positively contributed to their learning (78%) and provided better understanding and application of the material learned in an integrated classroom course (74%). They believed that the sessions affected their view about medicine (73%), and should be continued in future courses (80%). The percentage demonstrates the average of all courses. The program helped the students learn how to apply basic sciences concepts to clinical medicine. Evaluation of the program indicated that students found the sessions beneficial to their learning.

The present study aimed to compare the serum level of uric acid in patients with and without heart failure and also to determine the association between uric acid level and clinical status by Killip class in patients with STEMI. This case-control study was conducted on 50 consecutives as control group and 50 patients with acute heart failure, (20 patients had acute STEMI), who documented by both clinical conditions and echocardiography assessment. The mean plasma level of uric acid in the case group was 7.6±1.6 milligrams/deciliter (mg/dL) and in the control group was 4.5±1.5 respectively (P

Background: The aim of this study was to compare the PID with bare skin (without PID) regarding bacterial recolonization and bacterial regrowth of the adjacent skin of surgical incision in lumbar spine surgery patients. Methods: This quasi-experimental study was conducted from February to May 2018 on 88 patients who were candidate for lumbar spine surgery. Patients were assigned to one of two groups, treatment (with PID) and control (without PID). Skin sampling (adjacent of surgical incision) for bacterial culture was done in two steps, immediately after surgical skin prep (IASSP) and immediately after surgical wound closure (IASWC) by researcher. Finally, samples were sent to the laboratory. Results: The mean total bacterial count of patient's skin in stage IASSP was not significantly different between treatment and control groups (0.34 vs 0.27, P = 0.68). However, mean total bacterial count in stage IASWC in treatment group was significantly higher than control group (2.2 vs 0.93, P = 0.03). The frequency distribution of S. aureus (P = 0.04) and S. epidermidis (P = 0.02) was significantly higher in treatment group compared with control group in stage IASWC. Conclusions: The results showed that using PID is unable to reduce recolonization and regrowth of bacteria on patients' skin adjacent to surgical wound in clean lumbar spine surgeries. However, making a definite decision about using or not using of PID requires further studies.

Background: Hemorrhoid is among the most common anorectal diseases and patients with high-grade disease conditions need surgical treatment. Many surgical procedures are available to treat the disease. The aim of this study was to compare the operative time and outcomes, (post-operative pain and complications) of LigaSure hemorrhoidectomy with those of the open conventional method.Methods : This randomized single-blind clinical trial included 57 patients (28 in LigaSure and 29 in the open group). The primary variable was the operative time for the excision of a single hemorrhoidal packet. The other variables were post-operative pain measured by morphine doses administered to control pain, scores of visual analogue scale (VAS) used to measure pain severity, pain during home stay measured by doses of oral ibuprofen and the mean daily VAS scores, early complications including bleeding and urinary retention, longer-term complications and time to return to work.Results : The demographic data were comparatively the same between the two groups. The average time to excise a single packet of hemorrhoid was significantly shorter in the LigaSure group (8.91 min vs. 17.35 min, P

Recently, effect of allopurinol in decreasing the production of ROS and improving cardiovascular pathogenesis has come into scientific interest. Animal studies have documented the benefit of allopurinol in improving left ventricular dilatation, hypertrophy and fibrosis, and myocardial contractility and in the prevention of systemic vasoconstriction. The aim of this study was to evaluate the effect of allopurinol in improving diastolic dysfunction in ESRD patients with hyperuricemia."n"nMethods: This was an interventional study on 28 patients (19 males and 9 females) with ESRD and hyperuricemia. At the end of a one-month course of allopurinol therapy (100 mg daily), echocardiographic indices of diastolic dysfunction were measured and compared to the baseline indices."n"nResults: The mean level of uric acid was 7.5±0.96 mg/dl. The mean EF before and after the study were %44.28±%9.8 and %44.64±%9.7, (no significant difference), Respectively. The two indices of IVCT and A reversal were shown to have significant improvement after therapy (p=0.028 and 0.012, respectively). The grading of diastolic dysfunction didn't improve significantly after treatment with allopurinol."n"nConclusion: Significant improvement in some of studied indices, reproduced only in male subgroup of patients that might be related to a better response of males to allopurinol, however, a longer course of treatment may result in more favorable responses. Better patient selection in terms of "EF"s with normal distribution and repeating the study in non-dialysis hyperuricemic patients may result in more accurate information.

Objective(s): To determine the prevalence and predictors of patient delay among patients with myocardial infarction. Methods: In this cross-sectional study, a sample of 95 admitted patients with confirmed diagnosis of myocardial infarction were included. They were asked about symptoms, the time from presentation to admission and the reason for delay, if any. Delay was defined as arrival to hospital after 3 hours from initiation of symptoms. Results: The mean age of patients was 60.4±1.1 years and mostly were male (76.8%). Half of the patients had visited the doctor 9 hours after the pain started or later (median). About 70 percent of patients had delayed seeking medical care after myocardial infarction. The risk factors for delay in the descending order of importance (OR) were: lacking sweat as a symptom, heart attack at midnight, lacking previous history of heart disease, visiting a general practitioner, gradual onset and lower educational level. Conclusion: Education of the general public especially individuals with lower educational status can lead to better recognition of symptoms and decrease patient delay.

Bile duct injuries are well-known complications of laparoscopic and open cholecystectomies. Here, we report anastomosis of the common bile duct to the transverse colon that occurred as a complication of laparoscopic cholecystectomy. To the best of our knowledge, a similar case has not been reported in the literature so far. As in our patient, persistent diarrhea (in addition to fever and icterus) can be a warning sign of complication after these procedures. Surgeons who do advanced laparoscopic techniques must be familiar with this complication.
