Prevalence, characteristics, and risk factors of non-alcoholic fatty liver disease in North East of Iran: a population-based study.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is a common dietary disorder caused by fatty changes in the liver parenchyma and hepatocytes without alcohol consumption. The present study aimed to investigate the prevalence, characteristics, and risk factors of NAFLD in the Mashhad Persian Cohort Study population. METHOD: The present population-based cross-sectional study included all PERSIAN Organizational Cohort study in Mashhad University of Medical Sciences (POCM), Mashhad, Iran by census sampling method. Eligible participants were divided into two groups due to their NAFLD condition (NAFLD positive or NAFLD negative). All enrolled participants were evaluated based on their clinical aspects, anthropometric measures, laboratory tests, and ultrasound features. Statistical analysis was conducted using SPSS software version 16 (SPSS Inc., Chicago, USA -version 16). A P-value less than 0.05 was considered as the significance level. RESULTS: A total of 1198 individuals were included in the study, of which 638 (53.3%) were male and the rest were female. The mean age of the participants was 46.89 ± 8.98 years. A total of 246 patients (20.53%) were NAFLD positive, of which 122 (49.59%) were in grade 1, 112 (45.52%) were in grade 2, and 12 (4.87%) were in grade 3. The prevalence of fatty liver was significantly higher in males than in females (p < 0.001). There were significant differences between NAFLD positive and NAFLD negative participants in terms of having a history of hypertension (P = 0.044), body mass index (P < 0.001), body fat percentage (P = 0.001), waist circumference (P < 0.001), liver craniocaudal length (P = 0.012), fasting blood sugar (FBS) (P = 0.047), aspartate aminotransferase (AST) (P = 0.007), and alanine aminotransferase (ALT) (P = 0.001). Further analysis revealed a strong significant association between BMI, previous history of hypertension, higher levels of serum ALT, and NAFLD (P < 0.05). CONCLUSION: It can be concluded that ultrasound findings accompanied by laboratory AST and ALT level enzymes could be a cost-benefit approach for NAFLD early diagnosis. The craniocaudal size of the liver could be a beneficent marker for estimating the severity of the disease; however, more studies are recommended to evaluate this variable for future practice against the issue.

Addiction and the Risk of Common Bile Duct Stones: A 4-Year Retrospective Population-Based Study in Mashhad, Iran.

Background: As a common digestive disorder, choledocholithiasis can have serious consequences, including death. Given that opioids have been shown to contribute to the spasm of Oddi's sphincter, which results in biliary stasis in the common bile duct (CBD), it is likely that opioids can also raise the prevalence of choledocholithiasis. In this regard, this study aimed to investigate how common opium addiction was among choledocholithiasis patients in Mashhad, Iran. Methods: The current retrospective observational study was conducted on 599 patients with choledocholithiasis who underwent endoscopic retrograde cholangiopancreatography (ERCP), utilizing information gathered at the Ghaem hospital in Mashhad, Iran, between 2011 and 2015. Patient data were collected from files and records using certain criteria such as gender, opium addiction, hepatic enzymes (AST, ALT, ALP), plasma levels of total bilirubin, and direct bilirubin. The size of the CBD stones as well as the correlation between the gallbladder and CBD stones were calculated. Findings: From among 599 patients included, 345 (57.6%) were female and 254 (42.4%) were male. Moreover, 195 patients (32.2%) had opiate addictions. The size of the CBD stone was correlated with the patient's age (r=0.17, P=0.001). The average stone measured 12.22±3.32 mm. There were notable differences in the mean size of the CBD stone (P<0.001) between addicted and non-addicted cases; specifically, the mean CBD stone size in addicted cases was 12.715.13 mm while it was 12.34.33 mm in non-addicted cases. Conclusion: This study showed patients with CBD stones have a higher rate of opium addiction compared to the general population, indicating a possible link between the two conditions.

Early clinical exposure as a highly interesting educational program for undergraduate medical students: an interventional study.

BACKGROUND: Training professional medical experts is so much dependent on the efficacy of the medical curriculum. Bearing this in mind, we aimed to evaluate the attitude of the undergraduate medical students toward the Early clinical exposure (ECE) program as a facilitator transition to the clinical phase. METHODS: This quasi-experimental study was conducted on undergraduate medical students at the Mashhad University of Medical Sciences, Mashhad, Iran who were transferring from the pre-clinical course to the externship course from 2021 to 2022 by census method (i.e. all eligible students were included and no sampling was performed). An eight-session ECE intervention was performed on the participants by two professors of the Internal medicine department of Ghaem Hospital, Mashhad University of Medical Sciences, Mashhad, Iran. The participants' attitude toward the program and the program quality was assessed with the valid and reliable scale developed by Mirzazadeh et al. (Cronbach's alpha = 0.72). Statistical analyses were performed by SPSS software (version.16) with a statistically significant level of less than 0.05. RESULTS: A total of 118 undergraduate medical students were enrolled in the study. Our results revealed that this program could familiarize (n = 95,81.2%)the students with the role of basic sciences knowledge in clinical settings, and 104(88.9%) participants believed that this intervention could motivate them toward learning more. The data revealed that this program was highly interesting for international students. There was a significant differentiation between Iranian and international students in familiarity with doctoring skills in medicine(P < 0.001), familiarity with the roles and responsibilities of clinical students(P < 0.001), and utility of early clinical exposure and providing more experiences(P < 0.001). According to the students' reports, the major strengths of the program were familiarizing themselves with the clinical fields, having excellent instructors, and performing admirable training. On the other hand, the major weakness of the program was the short duration and the high population of participants in each group. CONCLUSIONS: The ECE program had a positive impact on the students' satisfaction with medical education, and it also enhanced their understanding of the role they will play as future physicians. Therefore, we recommend that this program be implemented as a part of the medical education curriculum in medical universities.

Serum interleukin-18 and its relationship with subclinical atherosclerosis in systemic lupus erythematosus.

BACKGROUND: Interleukin-18 (IL-18) is a pro-inflammatory and pro-atherogenic factor, and its blood level has shown a direct correlation with atherosclerosis. We aimed to evaluate the serum IL-18 level in patients with systemic lupus erythematosus (SLE) and its relationship with the intima-media thickness (IMT) of the carotid artery in these patients, as an indicator of atherosclerosis. METHODS: In this cross-sectional study, 60 patients as the patient group and 30 healthy volunteers as the control group [matched sex, age, and body mass index (BMI)] were selected, and their disease status and general data were gathered using the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K) form. A blood sample was also obtained from all participants to determine the serum level of IL-18 and other metrics, including high-sensitivity C-reactive protein (hs-CRP), cholesterol, triglyceride (TG), low-density lipoprotein (LDL), high-density lipoprotein (HDL), anti-double stranded deoxyribonucleic acid (anti-dsDNA), complement 3 (C3), and C4. The IMT of the carotid artery was calculated in both groups. We also evaluated the clinical cardiovascular manifestations. RESULTS: The serum IL-18 levels in patients were significantly higher than in the control group (P ˂ 0.005). It had no significant correlation with disease activity (P = 0.10). The patients with SLE with high IL-18 serum levels (> 280 pg/ml) had higher SLEDAI-2K (P = 0.02) than the patients with a low level (< 280), where 280 was the median of the IL-18 levels. The serum IL-18 level had no significant correlation with the carotid artery IMT. CONCLUSION: A high level of IL-18 reflects the disease activity, but it was not significantly correlated with subclinical atherosclerosis, denoted by the carotid artery IMT.

Allopurinol and Loss of Consciousness in a 78-old Year Man Suffering from Gout.

Allopurinol is an FDA -Approved xanthine oxidase inhibitor, which is effective in the treatment of gout, hyperuricemia and uremic kidney stones in patients with an increased level of uric acid excretion. Xanthine oxidase acts by converting hypoxanthine and xanthine into uric acid, and therefore its inhibition results in decreased production of uric acid. The most common side effects of this medication are as follows: maculopapular rashes, hives, itching, headache, dizziness, abnormal hair loss, fever and hypersensitivity reaction. Case Presentation: This report represents a case of drug-induced meningitis of a senile man who ended up in the ICU due to the remarkably reduced state of consciousness.

Electrocardiographic Changes Following Acute Hydralazine Overdose.

Hydralazine is an FDA-approved antihypertensive agent which has been utilized for years either alone or in combination with other medications especially the beta-blockers. Hydralazine works as a direct-acting vasodilator, thereby exerting a decrease in vascular resistance and increase in intravascular volume. When overdosed, hydralazine applies its toxic effects by extending its pharmacological action, which produces hypotension, syncope, tachycardia, and nausea. However, studies and case reports of acute hydralazine toxicity and its effects on electrocardiographic changes are rare, and most of the medical literature have only highlighted its immunological side effects. In this report, we are presenting a case of acute hydralazine overdose in a young woman who ended up in CCU due to remarkably abnormal electrocardiogram and unstable hemodynamics followed by myocardial infarction.

Effect of Oral Methadone on ECG Characteristics and Endocrine Hormonal Changes and Their Inter-relationship.

INTRODUCTION: Methadone is the most common opioid in use for opioid substitution therapy. The relation of methadone and electrocardiographic findings is nearly well known while the relationship between its electrocardiographic indexes and hormonal changes is not well recognized. OBJECTIVE: To evaluate the hormonal changes in patients who are taking methadone maintenance treatment (MMT) and its effects on electrocardiographic indexes, in comparison with healthy control groups. PATIENTS AND METHODS: 40 patients receiving MMT therapy for at least last six months and 40 healthy subjects were enrolled in the study. Serum estradiol, testosterone, luteinizing hormone, follicle stimulating hormone and thyroid function tests were measured. Mean QT Interval, P-R Interval (PRi) and QRS duration were also documented in maximum. RESULTS: There were no significant differences in hormonal parameters between MMT and control groups. No significant relation was found between hormonal parameters, dose and duration of methadone usage in patients group. QTc was significantly higher in methadone users than control groups. QTc had a significant negative correlation with Testosterone level (r=-0.581, P=0.007) in males. Significant difference was found between PRi in patients and control groups (P=0.007). CONCLUSION: Electrocardiographic changes are an important complication of methadone that seems to be related to low testosterone level in men.
