RESUMEN

Objectives: Proximal humerus fractures (PHFs) are common fractures in the elderly and are typically treated conservatively with immobilization. However, there is no consensus on whether to choose early or late conventional mobilization, taking their outcomes into account. This paper reviews comparative studies on the clinical outcomes of one- and three-week immobilization periods in terms of limb function, pain intensity, and complications following the adoption of the non-surgical treatment of PHF. Methods: The current systematic review started with searching PubMed, Scopus, and Web of Science databases for randomized clinical trials (RCTs) on PHF patients to compare the clinical outcomes between patients receiving the one-week mobilization (early mobilization) and those receiving the three-week mobilization (late mobilization). We also performed a meta-analysis to compare the two groups' limb function and pain levels at three and six months of follow-up. Results: Five of the seven RCTs had adequate data to be included in the meta-analysis. The quantitative results showed that the early mobilized patients had improved limb function at three [weighted mean difference (WMD): 5.15 (CI 95%: 0.68-9.62)] and six [WMD: 3.51 (CI 95%: 0.43-6.60)] months, but not at 12 months of follow-up. At either three, six, or 12 months, there was no difference in pain intensity between the two groups. Conclusion: This review supports the adoption of early mobilization at one week for the non-operative management of PHFs. However, to compare the long-term effects, more clinical trials with longer follow-ups are needed.

RESUMEN

Over the past three years, the COVID-19 outbreak has become a major worldwide problem, affecting the health systems and economies of countries. The mean delays, the expected time to observe the average effect of the number of new cases on the number of deaths, are gold times for decision-making regarding disease control and treatment facilities to reduce the fatality rate. The interest of the present study is estimating the mean delays and adjusted fatality rates of COVID-19 with the new application of Distributed Lag Models (DLM) and their spatial distributions. The daily cases and deaths data of COVID-19 for 39 European countries was obtained from two sources; the "European Centre for Disease Prevention and Control" and the "Our World in Data" database. The mean delay and the Adjusted Fatality Rate (AFR) for each country at three-time intervals; the first and subsequent peaks before and after vaccination were estimated by the Distributed Lag Models. The spatial analysis was applied to find the spatial correlation of the mean delays and adjusted fatality rates among European countries. In the three-time intervals, the first and the subsequent peaks before vaccination, and after vaccination, the median and interquartile range of the mean delays; and AFRs were: 1.1 (0.4, 3.2); 0.024 (0.016, 0.044), 9.2 (6.2, 12.40); 0.013 (0.005, 0.020) and 7.3 (4.4, 11.0); 0.001 (0.001, 0.005), respectively. In the subsequent peaks before vaccination, the mean delays considerably increased, and the AFRs decreased for most European countries. After vaccination, the AFRs decreased considerably. Except for the first peak, the spatial correlations of AFRs were not significant among neighboring countries. Consecutive outcomes will occur with delays in outbreaks of infectious disease. Also, the fatality rates for these outcomes should be adjusted on delays. Estimating the mean delays and adjusted fatality rates by Distributed lag Models and the spatial distributions of theme in outbreaks showed that prevention and medical policies after the first peak as well as vaccination were effective to reduce the fatality rate of COVID-19, but these effects were different between countries. These results recommended policymakers and governments assign prevention and medical resources more effectively.

RESUMEN

INTRODUCTION: The COVID-19 pandemic has caused physical and psychological health problems in the elderly. Spiritual intelligence has an effect on health and healing. The aim of this study determining the relationship between spiritual intelligence and intolerance of uncertainty, anxiety, and fear of corona in the elderly. METHODOLOGY: A cross-sectional study was done on 207 elderly people who referred to comprehensive health service centers in Mashhad in 2022. The samples were selected based on the inclusion criteria using multistage and cluster sampling. To collect data, various questionnaires were used, including demographic characteristics (age, gender, marital status …), King's Spiritual Intelligence Questionnaire, Freestone's Intolerance of Uncertainty Questionnaire, Corona Anxiety Scale, and Coronavirus Fear Scale. Statistical analysis of variables was done using descriptive and analytical (independent t-test, Mann-Whitney, analysis of variance, linear regression) tests by means of STATA version 14. RESULTS: The average level of spiritual intelligence was 54.1. Participants reported a high level of intolerance of uncertainty (M = 79.2) and fear of corona (M = 14.09). Education, economic status, and marital status were the predictors of spiritual intelligence of the studied subjects (r = 0.24, P < .05). Spiritual intelligence and gender were also related to uncertainty intolerance (r = 0.12, P < .05). Another finding of the study was the superiority of variables of spiritual intelligence and gender in predicting the level of anxiety of corona compared to other variables (r = 0.17, P < .05). CONCLUSION: There was a relationship between spiritual intelligence, education, and gender with the level of fear and anxiety of corona. Therefore, planning and implementing educational projects based on increasing spiritual intelligence for the elderly with priority for elderly women and with a low level of literacy and income is recommended.

RESUMEN

BACKGROUND: Job burnout syndrome is caused by prolonged exposure to difficult working conditions. Emergency medical services (EMS) staff are exposed to varying levels of mental workload (MWL) depending on the operation, so it is more likely that they experience burnout syndrome. OBJECTIVE: The main aim of the current research was to investigate the effect of MWL, work-related and socio-demographic factors on job burnout among Iranian EMS staff. METHODS: The current cross-sectional and descriptive-analytical research was carried out among 198 EMS. In doing so, the Maslach Burnout Inventory (MBI), The NASA task load index (NASA TLX), and an author-developed work-related and socio-demographic factors were distributed among participants to collect data. The data were analyzed using descriptive and inferential statistics (t-test, ANOVA test, multiple linear regression, and Pearson correlation coefficient). RESULTS: The results showed a significant statistical relationship between burnout and MWL. A significant statistical relationship between overall workload and two dimensions of MBI, namely, emotional exhaustion and depersonalization were observed (P < 0.05). Moreover, a significant statistical difference regarding the mean of burnout in the different groups of educational levels and occupational categories were observed. CONCLUSIONS: The EMS staff generally reported moderate levels of MWL and burnout. Findings showed that socio-demographic and occupational factors had little effect on burnout. MWL, education levels, and occupational categories are the main predictors of job burnout.

RESUMEN

BACKGROUND: After a coronary artery bypass graft (CABG), diabetic patients deal with various hemodynamic disorders. This study aimed to compare the effect of cardiac rehabilitation (CR) on the functional capacity of diabetic and nondiabetic patients following CABG. METHODS: This descriptive-analytical study was performed on 40 diabetic and nondiabetic patients attending a similar CR program following CABG. The subjects were selected by convenience sampling and were divided into two diabetes and nondiabetes groups. All patients attended 24 exercise sessions held 3 days a week. The functional capacity of patients was measured and recorded with the metabolic equivalent of Task criterion before and after the CR program. In addition, data analysis was performed in SPSS version 19. RESULTS: In this study, the mean age of the diabetic and nondiabetic patients was 54.45 ± 5.82 and 56.85 ± 5.36 years, respectively. There was no significant difference between the research groups regarding the systolic and diastolic blood pressure (P > 0.05). The mean functional capacity in the diabetes and nondiabetes groups was 4.5 ± 0.79 and 5.2 ± 1.7 before the rehabilitation, respectively. However, the results of Mann-Whitney U-test were indicative of a lack of a significant difference in this respect (P > 0.05). After the CR program, the mean functional capacity in the diabetes and nondiabetes groups was 5.7 ± 1.31 and 6.3 ± 1.7, respectively, demonstrating an insignificant difference in this regard (P > 0.05). CONCLUSIONS: According to the results of the study, there was no significant difference between the diabetic and nondiabetic patients, who underwent CABG, after a CR program. However, replication of the study is warranted.

RESUMEN

BACKGROUND: Gastric cancer (GC) is the first and the third prevalent cancer among males and females in Iran, respectively. The aim of this study was mainly to identify high-risk areas of GC by assessing the spatial and temporal pattern of incidence, and second, to explore some risk factors of GC in ecological setting. METHODS: In this cross-sectional ecological study we used Bayesian hierarchical space-time model to measure the relative risk and temporal trends of GC in Iran from 2005 to 2010 based on available data. Data analysis was done by the use of integrated nested Laplace approximation Bayesian approach in R software. RESULTS: Overall trend of GC was significantly decreasing during the study period. Ardabil, Khorasan Razavi, West Azarbaijan, Zanjan, and Mazandaran provinces had the highest risk of incidence. Overweight and smoking were directly and significantly associated with GC risk. CONCLUSIONS: During the study period, GC has decreased in Iran. Nevertheless, GC risk was generally high in Northern and Northwestern provinces of Iran. Different health policies according to GC risk and trend are required for each province. Improvements in screening and education programs and conducting further epidemiological studies could help to reduce the incidence of GC in high risk provinces.

RESUMEN

BACKGROUND: Restless leg syndrome (RLS) is a common symptom of some diseases specially observed during hemodialysis. Cooling the dialysate is a safe and nonpharmacological method. The aim of this study was to assess the effect of cool dialysate on RLS in hemodialysis patients. MATERIALS AND METHODS: A total of 79 patients were selected for screening based on the four main criteria set by the RLS International Association. Finally, in line with the inclusion and exclusion criteria, 63 hemodialysis patients were recruited and participated in this clinical trial. The patients were randomly assigned to the intervention group (n = 32) and the control group (n = 31). The intervention group received 35.5°C dialysate and the control group received 37°C dialysate three times a week for a period of 1 month. The severity of RLS was measured in both groups using a standardized RLS questionnaire. Using R software version 3.3.1, the data were analyzed using the Student's t-test, and Wilcoxon test, at 95% confidence interval. RESULTS: In terms of RLS severity, there was no significant difference between intervention and control groups before the intervention (t = -2.11, p > 0.05). After the intervention, the mean (SD) of RLS severity in the control group was 28.77 (5.45) and in the intervention group was 11.66 (4.69), in which t test showed a significant difference between two groups (t = 14.03, p= 0.001). CONCLUSIONS: Using cool dialysate as a nonpharmacological treatment may reduce the severity of RLS in patients on hemodialysis. Therefore, using this method to improve RLS in hemodialysis patients is recommended.

RESUMEN

INTRODUCTION: Primary dysmenorrhea, painful menstruation without pelvic pathologic complications, is one of the most common problems in women's gynecology and is one of the main causes for women referring to the clinic. Overweight and obesity may play a role in the etiology of primary dysmenorrhea. As a result, this study was conducted to determine the association between primary dysmenorrhea and anthropometric indices in female high school Students. METHODS: This descriptive, cross-sectional study was conducted on 200 high school female students with primary dysmenorrhea in 2017 in Sabzevar. Anthropometric indicators were considered by the students if they had entry criteria. Data analysis was done using SPSS software. RESULTS: The results of data analysis showed that there was a significant difference between the presence of dysmenorrhea and anthropometric indices at height P = 0.05, waist circumference P = 0.03, waist circumference with height P = 0.01, height to waist circumference P = 0.01, thigh circumference to height P = 0.04, height to thigh circumference P = 0.04, waist circumference to hip circumference P = 0.04, hip circumference to hip circumference P = 0.05, and No significant relationship was found between the other indicators. CONCLUSION: Adherence to a balanced diet and proper lifestyle can prevent dysmenorrhea in adolescent girls.

RESUMEN

BACKGROUND: Reported age standardized incidence rates for esophageal cancer in Iran are 0.88 and 6.15 for females and males, at fifth and the eighth ranks, respectively, of cancers overall. The present study aimed to map relative risk using more realistic and less problematic methods than common estimators. MATERIALS AND METHODS: In this ecological investigation, the studied population consisted of all esophageal cancer patients in Iran from 2005 to 2007. The Bayesian multilevel space-time model with three levels of county, province, and time was used to measure the relative risk of esophageal cancer. Analyses were conducted using R package INLA. RESULTS: The total number of registered patients was 7,160. According to the results, the three-level model with adjustment for risk factors of physical activity and smoking had the best fit among all models .The overall temporal trend was significantly increasing. At county level, Ahar, Marand, Salmas, Bojnoord, Saghez, Sarakhs, Shahroud and Torbatejam had the highest relative risks. Physical activity was found to have significant direct association with risk of developing esophageal cancer. CONCLUSIONS: Given to great variation across geographical areas, many different factors affect the incidence of esophageal cancer. Conducting further studies at the individual level in areas with high incidence could provide more detailed information on risk factors of esophageal cancer.
