Importance of viral pathogens in children with acute gastroenteritis in the south of Iran
Different types of viruses are the leading cause of acute diarrhea among infants and young children worldwide. Epidemiological surveillance of viral agents is critical for the develop.ment of effective preventive measures, including vaccines. This study aimed to determine the prevalence of the four major enteropathogenic viruses-rotavirus, norovirus, adenovirus and astrovirus-in children over 7 years of age.
DESIGN AND SETTING:
A cross-sectional descriptive study conducted on stool specimens of children with acute gastroenteritis admitted to the Pediatrics Unit of 17 Shahrivar Hospital in Borazjan, Iran from October 2008 to September 2010.
PATIENTS AND METHODS:
Acute gastroenteritis was defined as >=3 loose watery stools per 24 hours. A total of 375 stool samples were collected from hospitalized children aged < 7 years old with acute gastroenteritis. All samples were investigated by using enzyme-linked immunosorbent assay for the presence of viral antigens.
RESULTS:
Rotavirus was detected in 91 (24.3%) of the patients whereas the prevalence of norovirus, adenovirus and astrovirus was 12.5%, 5.1% and 2.4%, respectively. On average, 75.9% of children with viral diarrhea were younger than 2 years old (P=.023). All the strains of viral gastroenteritis studied peaked in the autumn, except for adenovirus which peaked in spring (P=.015). The most common clinical symptoms included diarrhea (92.2%), vomiting (68.7%), abdominal cramp (60.8%) and moderate dehydration (57.2%).
CONCLUSION:
Since nearly half of gastroenteritis cases (44.3%) were due to viral agents, testing for the viral antigens may guide the clinical approach to those patients with acute diarrhea particularly in the case of children less than 2 years old, and during cold seasons
The Effect of Mannitol and Hypertonic Sodium Administration on Hemodynamic Parameters Under LiDCO Monitoring in Patients Undergoing Elective Craniotomy
In craniotomy surgery, it is important to maintain hemodynamics and prevent the increase of intracranial pressure. Using semi-invasive methods such as LiDCO monitoring is a good option in this situation. This study aimed to evaluate the effectiveness of mannitol and hypertonic sodium on hemodynamic parameters in patients undergoing elective craniotomy. This randomized clinical trial was done on 40 patients of both genders. Patients whose ages were between 18-65 years, who had American Society of Anesthesiologists (ASA) score I and II, and who underwent craniotomy surgery were eligible for this study. Participants were divided into two groups receiving hypertonic sodium and mannitol. Hemodynamic parameters were evaluated before surgery, 20 minutes, and 60 minutes after surgery in both groups, under Lithium dilution cardiac output (LiDCO) monitoring. The results showed that there was no difference between groups in terms of the average fluid intake, the duration of the operation, the amount of urinary output, and the primary hemodynamic characteristics. Significant differences were recorded in the evaluation of hemodynamic parameters. The results demonstrated a reduction in systolic, diastolic, and mean arterial blood pressure during 20 to 60 minutes after mannitol injection compared to hypertonic sodium injection. Additionally, the effectiveness of both therapies on maintaining cardiac function was similar, but the use of mannitol led to a greater decrease in arterial and peripheral vascular resistance. It can be concluded that mannitol may be more effective than hypertonic sodium during craniotomy procedures in terms of reducing blood pressure monitored with LiDCO
Evaluation of the Role of Hemoperfusion on Mortality and Morbidity in Patients with Severe Coronavirus Disease 2019 (COVID- 19)
Background: Cytokine storm in severe Covid-19 disease is one of the leading causes of death in these patients. Hemoperfusion is a method used to purify the blood from toxins and inflammatory factors. The aim of this study was to evaluate the effect of hemoperfusion on mortality and morbidity in patients with severe Covid - 19 disease.
Methods: This was a retrospective study which performed by reviewing the files of 30 patients with severe Covid-19 disease referred to Sina Hospital affiliated to Tehran University of Medical Sciences in 2020. Thirty patients with severe covid-19 disease and positive PCR participated in the study. All patients received routine treatment protocol for covid-19. Hemoperfusion was used for 15 patients in addition to receiving routine care. The remaining 15 patients were included in the control group. Patients in the hemoperfusion group underwent four sessions of hemoperfusion using continuous renal replacement therapy with continuous venovenous hemofiltration.
Results: the ICU length of stay in the control and hemoperfusion groups was 3.40 ± 11.40 and 9.65 ± 16.33 days, respectively (P= 0.075). 8 patients died and 7 patients were discharged in the control group, but 11 patients died and 4 patients were discharged in the hemoperfusion group (P= 0.256). The respiratory rate of patients in the control and hemoperfusion groups decreased from 7.43 ± 29.40 to 4.03 ± 24.60 and from 6.11 ± 31.60 to 5.04 ± 24.46, respectively (P < 0.001). The percentage of arterial blood oxygen saturation in the control and hemoperfusion groups increased from 90.86 ± 5.61 to 93.06 30 4.30 and from 92.33 26 3.26 to 92.06 31 5.31, respectively (P= 0.456).
Conclusion: Hemoperfusion could not prevent the mortality of patients and finally out of 15 patients, 11 patients died and 4 patients were discharged. Also, no significant difference was observed between the two groups in terms of arterial blood oxygen saturation
Comparative Analysis of Patient Satisfaction and Sedation Outcomes in Bronchoscopy: Fentanyl/Chlorpheniramine vs. Ketamine/Chlorpheniramine
This randomized clinical trial aimed to assess and compare patient satisfaction and sedation outcomes in bronchoscopy procedures using two distinct sedation protocols: fentanyl/chlorpheniramine (FC) and ketamine/chlorpheniramine (KC). Ninety patients undergoing simple bronchoscopy and bronchoalveolar lavage were randomly assigned to receive either FC (1 µg/kg fentanyl and 10 mg chlorpheniramine) or KC (0.5 mg/kg ketamine and 10 mg chlorpheniramine). Lidocaine was also administered during bronchoscopy. Primary outcomes included patient satisfaction scores, while secondary outcomes encompassed sedation levels, bronchoscopist satisfaction, cough rates, lidocaine usage, and physiological parameters. Patients in the FC group exhibited significantly higher satisfaction levels compared to the KC group (P=0.002). Bronchoscopist satisfaction was also superior in the FC group (P=0.001). Although cough rates did not differ significantly, severe persistent coughs were more prevalent in the KC group. Physiological parameters such as oxygen saturation were comparable, but the KC group demonstrated higher increases in systolic blood pressure and heart rate. The use of fentanyl/chlorpheniramine resulted in higher patient and bronchoscopist satisfaction during simple bronchoscopy and bronchoalveolar lavage compared to ketamine/chlorpheniramine. This study suggests that the combination of fentanyl and chlorpheniramine may be a preferable sedation choice for bronchoscopy procedures
Platelet kinetics after slow versus standard transfusions: A pilot study
Background. Platelet transfusion is required in the acute phase of some thrombocytopenic disorders in order to prevent potentially dangerous hemorrhages. The purpose of this study was to assess the increase in platelet count following a slow platelet transfusion.
Methods. Patients suffering from thrombocytopenia due to various underlying diseases were enrolled in the prospective pilot feasibility trial and were randomly divided into two groups. Standard platelet transfusion was administered in one group, while slow transfusion was used in the other. The platelet count was examined at 1 hour, 24 hours, and 1 week following the transfusions.
Results. Although the platelet count was higher following 1 hour after transfusion via the standard method, the count tended to be higher 1 week after the transfusion in the slow transfusion group. This difference, however, only turned out to be statistically significant amongst females.
Conclusion. A therapy of slow platelet transfusion might be more effective for the prevention of platelet loss. Further studies will be required to strengthen this hypothesis
Development of a Balanced Scorecard Suitable for Health Care Centers Based on DANP Hybrid Multi-Criteria Decision Making
Background and Aim: Parallel to the progress of services, organizational complexity levels in health care centers (HCCs) have increased. The influential factors in this regard include the variety of services, the non-uniformity of the centers’ management conditions, and the rising expectations from the health system. Therefore, considering many factors influenced and effective, improvement of health services requires development of a systematic approach to evaluate their efficiency and management system. The aim of this study was to develop a balanced scorecard (BSC) model suitable for HCCs using a hybrid approach that combines the Fuzzy Delphi and DNAP techniques.Â
Materials and Methods: This research was a combined qualitative-quantitative study that was conducted with the aim of developing a BSC model suitable for HCCs. The statistical population consisted of 15 experts in health and medicine, who were selected based on the targeted snowball sampling. A researcher-made questionnaire and a 20×20 matrix questionnaire were used to collect the data. The questionnaire validity was calculated based on the experts’ opinions and the reliability was calculated using Cronbach’s alpha and consistency rate. The data was analyzed using Excel and MATLAB, and DNAP technique was used to determine the cause-and-effect relationship and the influence levels of the objectives.Â
Results: According to the results of the Fuzzy Delphi technique in the panel of experts, 5 viewpoints with 20 objectives of the BSC suitable for HCCs were identified and replaced the traditional viewpoints of the BSC. In addition, these results showed that the views of growth and development, intra-organizational processes, and social responsibility are considered as the influential factors due to the positive D-R values, while the views of patients and society, financial status, and performance are considered as the factors that are effective due to the negative D-R values.
Conclusion: The results of this study indicated that those points of view that are consistent with the goals of the HCCs should be used in the BSC in order to evaluate their performance. Also, prioritizing and determining the cause-and-effect relationship and considering the contribution of each point of view for achieving the goals of the HCCs can increase the performance
Designing a Strategy Map for Healthcare Centers with Balanced Scorecard Approach
Background: Due to the level of complexity of healthcare organizations, many factors play a role in improving health services. Therefore, it is necessary to develop a systematic approach to evaluate their efficiency and management system. Balanced scorecard can play a role in this field as an evaluation system by examining the cause-and-effect relationship of goals and drawing a strategy map. Therefore, the purpose of this research was to develop a strategy map for healthcare centers with a balanced scorecard approach.
Methods: This was a qualitative and applied research conducted using mixed methods in 2019. The statistical population of the research included all health experts from medical sciences universities across the country, 15 of whom were selected based on a targeted snowball sampling. First, through the review of texts and articles related to the literature on the subject with a general search in foreign and domestic electronic databases, a list of balanced scorecard views and the goals related to health and treatment centers of comprehensive health service centers was identified. After that, through a researcher-made questionnaire, by asking experts their opinions using fuzzy Delphi method in 2 steps, the views and goals related to comprehensive health service centers were identified. Then, through the relationships of improved network analysis process technique based on DEMETEL, in 4 steps by Excel 2016 and Matlab 2014 software, the relationships between them were examined. Finally, the effect of goals and views on each other was determined, and a strategy map was drawn.
Results: In this research, social responsibility, as a new perspective and the attitudes of patients and society, financial status and performance improvement, growth and development, and internal processes, replaced the main perspectives of the balanced scorecard, and social responsibility was designated as a new perspective. By examining the relationship between them, the perspectives of growth and development, intra-organizational processes, social responsibility, and other views were found to be effective.
Conclusion: Considering the complexity of the activities regarding comprehensive health service centers, replacing the views appropriate to the comprehensive health service centers with the main views provided by Kaplan and Norton (2004) can obtain the best results regarding the goals and strategy. Based on the cause-effect relationship of views, strengthening views and effective goals creates value for effective goals. Investing on influential views and goals will empower and promote the development of balance between income and expense, and the optimal use of resources will improve the views of society and patients and the quality of services, which is the main goal of comprehensive health service centers

Relationship between blood peroxidases activity and visfatin levels in metabolic syndrome patients
Normal 0 false false false EN-US X-NONE FA BACKGROUND: The observed relationships between visfatin, peroxidases activity, and metabolic syndrome (MetS) are inconsistent; therefore, this study was undertaken to understand these relationships. METHODS: This cross-sectional study was conducted as a part of the Isfahan Healthy Heart Program. A blood sample of 90 MetS and non-MetS patients were used to estimate total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C), triglycerides (TGs), fasting blood glucose (FBG), waist circumference (WC), systolic blood pressure (SBP) and diastolic blood pressure (DBP), visfatin and peroxidases activity. Data analysis for MetS group was carried out in two ways. (1) MetS with three components and with >3 components. (2) MetS with hyperglycemia and without hyperglycemia. RESULTS: SBP, DBP, WC, FBG, TC, TG, LDL-C, and were higher and HDL-C levels was lower in MetS patients. There was a significant correlation between visfatin levels and peroxidases activity in MetS patients with three components. Levels of visfatin were significantly higher in male as compared to female subjects in the MetS with three components group. There was a significant decrease in peroxidases activity in >45 years old subjects in the MetS with >3 components group. A significant correlation was observed between serum visfatin levels and FBG in the MetS without hyperglycemia group. CONCLUSION: Peroxidases activities in MetS patients can be related to visfatin levels. Gender influences on peroxidases activity probably and was lower in female patients with MetS. Hyperglycemia does not influence peroxidases activities and visfatin levels. Keywords: Peroxidase, Metabolic Syndrome, Visfatin <!--[endif] --
