Impact of COVID-19 pandemic on road traffic injuries in Iran: An interrupted time-series analysis.

INTRODUCTION: Globally, the COVID-19 pandemic has affected the number of road accidents and deaths caused by them. The present study aimed to identify the effect of this epidemic on traffic accidents and their casualties in Iran. METHODS: In this study, Interrupted Time Series Analysis (ITSA) was used in a semi-experimental design to measure the impact of the restrictive policies of COVID-19 on road accidents. Data were collected retrospectively from the Iran Red Crescent Society data set for 31 provinces from March 2017 to February 2022. The information related to the number of road accidents, injuries, deaths, and deaths in the hospital was collected. The Newey-West method is used for estimation. Statistical analyses were carried out using R software version 3.6.1. RESULTS: Since February 2020 in Iran, the reduction in the number of road accidents and the number of injuries and deaths in these accidents was significant at 5% but the reduction of deaths in the scene and hospital was significant at 10%. In general, for all variables, the reduction trend was established only in the first months, and then it had an upward trend. CONCLUSION: In the early months of the COVID-19 epidemic in Iran, the number of road accidents and their casualties decreased. Policies restricting traffic, quarantine, and fines for violators can be reasons for changing people's behavior and travel patterns and also lead to a reduction in traffic accidents and fatalities. Such studies can explain the importance of the policies in changing behavioural patterns and can be used as a guide in future policies.

Intraoral Extranodal Natural Killer Cell/T-Cell Lymphoma of the Hard Palate.

Natural killer cell/T-cell lymphoma (NK/TL) is a rare subtype of non-Hodgkin's lymphoma (NHL) associated with the Epstein-Barr virus (EBV) and requires early detection, which can be very challenging. NK/TL often arises in the nasal cavity and can then spread to the oral cavity, but the case presented here is an unusual presentation of NK/TL in a 66-year-old edentulous male patient who initially presented an intraoral exophytic lesion in the palate that appeared within 3 months. We report the present case to highlight the challenges of reaching an accurate diagnosis given the diverse clinical manifestations of NK/TL.

The impact of common chronic conditions on health-related quality of life: a general population survey in Iran using EQ-5D-5L.

BACKGROUND: Diseases have undeniable effects on Health-Related Quality of Life (HRQoL). Chronic diseases, in particular, limit the productive potentials and HRQoL of individuals. EQ-5D is a very popular generic instrument, which can be used to estimate HRQoL scores in any diseases. The current study investigates mean HRQoL scores in certain chronic diseases and examines the relationship between utility scores and chronic diseases in Iran. METHOD: This cross-sectional study was carried out among the general adult population of Tehran. 3060 individuals were chosen by a stratified probability sampling method. The EQ-5D-5L questionnaire was applied. The utility scores were estimated using the Iranian crosswalk-based value set. The effect of chronic diseases on the HRQoL scores was derived by the Ordinary Least Squares (OLS) method. Data was analyzed using Stata version 13 software. RESULTS: The mean ± standard deviation utility and EQ-VAS scores were 0.85 ± 0.14 and 76.73 ± 16.55 in the participants without any chronic conditions. The scores were 0.69 ± 0.17 and 61.14 ± 20.61 in the participants with chronic conditions. The highest and lowest mean utility scores were related to thyroid disease (0.70) and Stroke (0.54), respectively. Common chronic conditions had significant negative effects on the HRQoL scores. Stroke (0.204) and cancer (0.177) caused the most reduction in the EQ-5D-5L utility scores. Lumbar disc hernia, digestive diseases, osteoarthritis, breathing problems, and anxiety/nerves cause 0.133, 0.109, 0.108, 0.087, and 0.078 reductions, respectively, in the EQ-5D-5L utility scores. CONCLUSION: This study provides insight into some common chronic conditions and their effects on the HRQoL. Policymakers and planners should pay attention to the effects of chronic conditions especially high prevalence one. They should adopt effective interventions to control this issue and increase health. The results of this study can also be beneficial in economic evaluation studies.

Estimation of Government Health Expenditures in Iran During 2006 to 2011, Using Panel Data.

The status of public resources in health has a positive and direct impact on this sector's outcomes because of its effect on the increase of social services. The government's ability to manage health expenditures greatly depends on identifying the determinants of these expenditures. Therefore, this study aimed to determine factors affecting the government health expenditures and estimate the related function in Iran during 2006-2011 using panel data. This was a cross-sectional and time-series study that was conducted using panel data analysis. In this study, the data were collected and categorized separately for each province from documents in the Ministry of Health and the Statistical Center of Iran. The results showed that there were positive associations between health expenditures and some factors including age group of 20 to 39 years (P = .04), the number of women (P = .001), the number of physicians, the number of hospital beds, and annual budget (P < .001). According to the results, it seems that allocating a part of health subsidies for increasing the insurance coverage of the age group of 20 to 39 years and also starting saving accounts can have an important effect on reducing health expenditures of this age group.

Evaluation of the Antifungal Effect of Chicory Extracts on Candida Glabrata and Candida Krusei in a Laboratory Environment.

AIM: This research has evaluated the extract's antifungal effects on Candida glabrata and Candida krusei in a laboratory environment. MATERIALS AND METHODS: In this research, to evaluate the antifungal effect and the minimal inhibitory concentration (MIC) determination of chicory extract, the Clinical and Laboratory Standards Institute (CLSI) was used. Candida glabrata and C. krusei funguses were procured from the Tehran Pasteur Institute; they were grown in the relative growing environment according to the required conditions. Also for further assurance about the macrodilution method reality, the agar well diffusion method was used. Finally, the obtained results were analyzed using the Statistical Package for the Social Sciences version 16 software. RESULTS: The MIC for the chicory extract was 50 µg/mL for C. krusei and 100 µg/mL for C. glabrata. On the contrary, in the evaluation of different concentrations of the chicory extract by the agar well diffusion method, C. krusei's lack of growth in similar concentrations was greater than that of C. glabrata. As a result, the findings related to both the methods of agar well diffusion and MIC prevention concentration maximization proved that C. krusei sensitivity to the chicory extract is more compared with the sensitivity of C. glabrata. CONCLUSION: Chicory extract has the benefits of low price, accessibility, and proper taste as compared with nystatin. It also has fewer side effects, and after a clinical test, it could be considered a proper candidate as an antifungal drug against infections caused by C. krusei and C. glabrata. CLINICAL SIGNIFICANCE: The results obtained from this research have shown that chicory extract has antifungal features and is the best choice as an antifungal drug because of its low price, accessibility, and proper taste as compared with nystatin.
