Volume 78, Issue 8 (November 2020)
Abstract
Background: Intravenous (IV) injection of drugs is one of the most common methods of drug prescription in hospitals, which is a complex, potentially hazardous and erroneous method; accordingly, it requires control methods to reduce the potential risks. This study focused on determining the frequency and types of different medication errors while preparing and administering mostly used IV drugs in three intensive care units (ICU) and one general department in AL-Zahra hospital, Isfahan, Iran.
Methods: This cross-sectional observational study was conducted for 6 months from September 2017 to March 2018. To determine the frequency of different medication errors, a quoting sampling method was applied to select and observe 400 cases of IV drug administrations. All nurses from any studied department were included in this study. Different stages of preparation and administration of the observed drugs were compared to an instructed checklist prepared by the clinical pharmacist.
Results: Totally, 75 nurses were recruited from ICU-1 (N=29), ICU-2 (N=18), ICU-3 (N=19), and nephrology (N=9) departments. Type of department and occupation were the influential factors on nursing errors; also, a significant relationship was found between different work shifts and the occurrence of nurses’ errors, mostly seen in the evening work shift (P=0.037). The mean of nurses’ errors in IV drug administration was not correlated with other factors including age, work history, and the number of patients managed by each one. Also, a positive correlation was found between the number of nurses in each work shift and the number of errors (P=0.008).
Conclusion: Medication errors in each stage of drug administration may lead to the hazardous clinical outcome or serious side effects such as thrombosis, infection or eventually lead to morbidity or mortality. Therefore, being aware of these errors and establishing observational policies can prevent unpleasant events related to drug administration.

Volume 79, Issue 10 (January 2022)
Abstract
Background: In patients with ST-segment elevation myocardial infarction (STEMI), Primary percutaneous coronary intervention (PCI) is the preferred reperfusion therapy. Timely primary PCI is essential in improving the clinical outcomes of these patients. The aim of this study was to evaluate the factors affecting balloon delay in STEMI treated patients by primary PCI and its relationship with major adverse cardiac events (MACE).
Methods: This prospective observational study was conducted on 143 cases of STEMI patients, who had the inclusion criteria and were treated by primary PCI, after obtaining written consent in Imam Khomeini hospital in Ahvaz, between May 2019 to May 2020. All-time components from symptom onset to PCI treatment include symptom-to-balloon time or ischemic time, symptom-to-door time and door-to-balloon time calculated. The incidence of major adverse cardiovascular events (MACE) including decompensated heart failure (DHF), acute coronary syndrome (ACS), sudden cardiac death (SCD) and cerebrovascular accident (CVA) was evaluated during 12 months follow up after primary PCI. left ventricular ejection fraction (LVEF) changes were evaluated 3 months after primary PCI.
Results: The median symptom-to-door time was 200.5 minutes (IQR: 90-438.75 min), the median ischemic time was 406 minutes (IQR: 231-671 min), and most patients had an ischemic time ≥120 minutes (92.4%) and door-to-device time ≥90 minutes (64.3%). The most common delay for treatment was in the symptom-to-door time (76.9%) and then the decision for primary PCI to transfer to the cat lab (17.5%). Overall, 59 (41.3%) of the patients experienced MACE during 1-year of follow-up, including ACS (13.3%), DHF (22.4%), cardiac death (9.8%) and CVA (2.1%). The patients age (OR: 0.96, P=0.020), LVEF changes (OR: 1.123, P=0.005) and STEMI type (OR: 0.705; P=0.039) predicted in-hospital MACE, while the symptom-to-balloon time (P=0.607) and door-to-balloon time (P=0.347) were not associated with MACE.
Conclusion: None of the time intervals were associated with the occurrence of MACE in one-year follow-up, and most STEMI patients were admitted to the hospital with a long delay. Therefore, efforts to shorten the time of hospitalization admission can help improve the MACE in STEMI patients under primary PCI in our medical centers.

Abstract
Background: Rheumatoid Arthritis patients are evaluated during treatment for various inflammatory factors such as C-reactive protein, Erythrocyte Sedimentation Rate, and Disease Activity Score, and other immune system-related factors. In the follow-up of patients with rheumatoid arthritis, hematologic factors associated with the immune system especially Platelet to Lymphocyte Ratio and Neutrophil to Lymphocyte Ratio are important. In this study, platelet to lymphocyte ratio and Neutrophil to lymphocyte ratio were compared in two groups of patients with and without ocular complications.
Methods: This cross-sectional study was performed on 246 patients with rheumatoid arthritis who were referred to the rheumatology clinic of Kermanshah from December 2018 to May 2019. This study was carried out in accordance with the approval of the ethics committee (IR.KUMS.REC1397.311) at Kermanshah University of Medical Sciences. Of these patients, 191 had no ocular complications and 55 patients had ocular complications and were matched for age and sex. The blood samples were taken from patients and blood cell count was measured by Sysmex KX-21 hematology analyzer. The Spearman correlation test was used to evaluate the relationship between platelet to lymphocyte ratio and neutrophil to lymphocyte ratio in both groups of patients without ocular complications and with ocular complications. The Disease Activity Score was compared between the two groups using the Mann-Whitney test.
Results: The results of this study showed no significant difference between NLR and PLR levels in both groups of patients without ocular complications and with ocular complications. But the results showed that DAS-28 was significantly lower in the group with ocular complications (P<0.0001).
Conclusion: In general, the results of the present study showed that the evaluation of inflammatory factors such as platelet to lymphocyte ratio and neutrophil to lymphocyte alone could not be judged in predicting the presence or possibility of ocular involvement, and the level of these factors in patients with ocular complications was affected. Other factors, such as the number of blood cells and the condition of each patient, are included.
 

Effect of cardiac rehabilitation on endothelial function in smoker patients with ischemic heart disease
Ahmad Reza Assareh , Marzieh Jafarpor, Mohammad Hossein Haghighzadeh, Nehzat Akiash,
Volume 80, Issue 6 (September 2022)
Abstract
Background: smoking enhances the risk of cardiac events in patients with coronary artery disease. So, it is necessary to evaluate the effects of exercise-based cardiac rehabilitation on endothelial function and functional capacity among smoker patients.
Methods: This randomized clinical trial study was conducted on 56 non-diabetic smokers with a history of percutaneous coronary intervention or coronary artery bypass graft surgery in Imam Khomeini Hospital from May to August 2015. Based on cardiac rehabilitation, patients were divided into intervention and control groups. Before rehabilitation, fasting blood sugar (FBS), lipid profile (LDL, HDL, triglyceride, and total cholesterol), and Ankle-Brachial Index (ABI) were measured for endothelial function. Besides, METs were measured based on the Duke activity status index. After 24 rehabilitation sessions (3 sessions of 1 hour each week for 2 months), all values were checked again and compared with the initial values.
Results: The mean age of the subjects in the cardiac rehabilitation and control groups were 61.18 and 52.32, respectively. Before the intervention, there were no significant differences between the two groups in terms of the ABI variables, BMI, systolic and diastolic blood pressure, LDL, triglyceride, total cholesterol and FBS; only HDL and  METs showed significant differences. After exercise-based cardiac rehabilitation, the mean rate of ABI changes was +0.078 on the right side of the body and +0.084 on the left side of the body. In the control group, these values were 0.002 and 0.003, respectively (P=0.001). The amount of changes in increasing METs as well as decreasing body mass index (BMI), and systolic and diastolic blood pressure in the rehabilitation group were statistically significant compared to the control group. In addition, there were no significant differences in terms of FBS and lipid profiles either (P>0.05).
Conclusion: Two months of cardiac rehabilitation with regular exercise was associated with improved ABI as an indicator of endothelial function and prognosis of cardiovascular disease, as well as improved cardiac functional capacity among smoker patients.
