Acute kidney injury (AKI) is a common complication after coronary artery bypass grafting (CABG) surgery and can be linked to the increased morbidity and mortality. Therefore, in the present study, the effect of preoperative administration of acetazolamide was evaluated to investigate whether it could prevent occurrence of post-operative AKI after CABG surgery. In this randomized controlled clinical trial, 130 patients who were candidates to undergo elective CABG surgery from January 21, 2020 to February 8, 2021 were randomly allocated to intervention group (receiving 500 mg of acetazolamide orally 2 h preoperatively) and control group. The patients were evaluated for AKI based on the kidney disease-improving global outcomes (KDIGO) criteria based on their serum creatinine (SCr) level and urine output until 7 days postoperatively. There was no significant difference in baseline demographics between the two groups. The total incidence of AKI was measured as 43%. Analysis of post-operative AKI incidence showed no statistically significant difference between the two groups (P = 0.860). Mean post-operative SCr level on day 1 was significantly higher in the acetazolamide group (P = 0.036). A significant difference was found in length of hospitalization stay between the groups, which was higher in the control group (P = 0.006). Our results did not demonstrate a significant protective effect of acetazolamide on incidence of post-operative AKI in the patients undergone elective on-pump CABG surgery. [ABSTRACT FROM AUTHOR]

Background: Multiple sclerosis (MS) is a chronic autoimmune disease and is one of the most costly medical conditions that imposed families with catastrophic health expenditures. There is an increasing trend in using alternative medicines including, dietary supplements, herbs, vitamins, and minerals. To date, the association between dietary as well as herbal supplements and QoL in MS patients is under researched; thus, this study aimed to assess the association between the self-reported supplement used and QoL between MS patients.Methods: This cross-sectional study was conducted on patients with MS referring to Shahid Kazemi Pharmacy, based in the city of Tehran, Iran, as a national pharmacy providing specialized pharmaceutical products and pharmaceutical care to patients. The Multiple Sclerosis Quality of Life-54 (MSQoL-54) tools was performed to evaluate MS patients QoL.Results: A total number of 382 patients with MS participated in this study. They include 89 (23.3%) men and 293 (76.7%) women, aged 40 ± 10.9 years old. The overall score of the MSQoL-54 questionnaire was 41.58 out of 100. Physical health composite (PHC) and mental health composite (MHC) were 69.60 and 62.99 from 100, respectively. This study revealed that 76.4% of patients used at least one vitamin daily; 92.4% of patients do not receive any herbal product. Vitamin D is the most widely used supplement, followed by calcium, while vitamin C is the least consumed. No correlation was observed regarding supplement use and overall QoL, PHC, or MHC. There were no significant differences between QoL's dimensions score in patients who used supplements. The results showed that increasing the number of supplements used did not relate to overall QoL, PHC, or MHC. In addition, there was not any correlation between the duration used of supplements and QoL's dimensions score in MS patients (p-value> 0.05).Conclusions: The dietary supplement appears to be popular among MS patients. The study results showed that the number of supplementations and their long-term use in patients with MS were not associated with higher QoL. Similarly, the herbal supplements have failed to improve QoL. [ABSTRACT FROM AUTHOR]

Background: Inflammatory mediators are an important component in the pathophysiology of the coronavirus disease 2019 (COVID-19). This study aimed to assess the effects of reducing inflammatory mediators using hemoperfusion (HP) and continuous renal replacement therapy (CRRT) on the mortality of patients with COVID-19. Materials and Methods: Twelve patients with confirmed diagnosis of COVID-19 were included. All patients had acute respiratory distress syndrome (ARDS). Patients were divided into three groups, namely, HP, CRRT and HP+CRRT. The primary outcome was mortality and the secondary outcomes were oxygenation and reduction in inflammatory mediators at the end of the study. Results: Patients were not different at baseline in demographics, inflammatory cytokine levels, and the level of acute phase reactants. Half of the patients (3 out of 6) in the HP+CRRT group survived along with the survival of one patient (1 out of 2) in the HP group. All four patients in the CRRT group died. Serum creatinine (SCr), Interleukin-1 (IL1), Interleukin-6 (IL6), Interleukin-8 (IL8), partial pressure of oxygen (PaO2), O2 saturation (O2 sat), and hemodynamic parameters improved over time in HP+CRRT and CRRT groups, but no significant difference was observed in the HP group (All Ps > 0.05). Conclusion: Combined HP and CRRT demonstrated the best result in terms of mortality, reduction of inflammatory mediators and oxygenation. Further investigations are needed to explore the role of HP+CRRT in COVID-19 patients. [ABSTRACT FROM AUTHOR]

Background: Gastric residual volume (GRV) is considered an important parameter for gastric emptying and nutrition tolerance. This volume is measured before any nutrition and has a direct effect on the volume and timing of the next nutrition. The present study aimed to examine the GRV via ultrasound after receiving intravenous ondansetron, metoclopramide, and neostigmine. Materials and Methods: In the present study, 40 patients were included in the study, 10 patients were excluded from the study due to death during treatment, and 30 patients were divided into three groups of 10(10 patients in each group). The first, second, and third groups received 2.5, 10, and 8 mg neostigmine, metoclopramide, and ondansetron every 8 h, respectively. The drugs were infused as a micro set in 100 ml normal saline into patients within 30 min. The patients underwent ultrasound imaging and GRV measurement by an intensive care unit (ICU) subspecialty fellow, who was not aware of the drugs received by the patients, in the 1st h of hospitalization, 6 h after drug injection, and once daily for 4 days. Results: A total of 40 patients entered the study based on inclusion and exclusion criteria. The effect of neostigmine on reducing GRV (Gastric residual volume) in ICU patients was better than those of the other two drugs, which was significant. Conclusion: The results of this study showed that neostigmine has a better and significant effect on reducing GRV in ICU patients, compared to those of ondansetron and metoclopramide.

Introduction. CKD is one of the most prevalent entities associated with high morbidity and mortality. Most of the patients with renal diseases, particularly patients undergoing dialysis, suffer from cardiovascular disease and it is necessary to employ appropriate strategies to prevent and manage this complication. The aim of this study was to evaluate the anti-inflammatory effects of omega-3 in patients undergoing CAPD. Methods. Nineteen CAPD patients with certain inclusion and exclusion criteria enrolled in this study. Omega-3 capsules with a dose of 1 g/d up to three months, were administrated. Some inflammatory markers such as ESR, CRP, HS-CRP, IL-6, MDA, and homocysteine were measured in three phases. In addition, lipid profile including triglyceride, cholesterol, LDL, and HDL were measured. Results. Results of this study showed that CRP, HS-CRP, and homocysteine levels increased insignificantly (P > .05) whereas, MDA level was increased significantly (P < .05). ESR and IL-6 levels both decreased but did not show any statistically significance (P > .05). Results of lipid profile also suggested that none of the lipid levels changed significantly (P > .05). Conclusion. It is necessary to design large trials in order to understand clear effects of omega-3 on inflammatory markers in PD patients. In addition, the results of this current pilot study should be interpreted with caution. [ABSTRACT FROM AUTHOR]

In the present study, the physicochemical properties and antioxidant activities of different Iranian honey samples are investigated using various multivariate techniques in order to develop a quality control model. Forty-eight Iranian honey samples were tested for 15 physicochemical and antioxidant parameters. The parameters for which the samples were tested included color intensity, moisture, electrical conductivity, pH, free acidity, diastase activity, hydroxymethylfurfural content, proline level, total phenolic content, antioxidant activity, and radical scavenging activity. The study attempted to differentiate honey samples based on origin and composition. In the study, the Iranian honey samples were classified according to their respective physiochemical properties and antioxidant activities using principal component analysis and hierarchical cluster analysis. Furthermore, the relationships between the geographical and botanical origins were determined for the samples used in the study. [ABSTRACT FROM AUTHOR]
