Purpose: Around 70% of the Iranian population had received two doses of coronavirus disease 2019 (COVID-19) vaccines by the end of 2021. In this study, we evaluated the reasons for vaccination refusal among people in Ahvaz, Iran. Materials and Methods: In this cross-sectional study, 800 participants (400 vaccinated and 400 unvaccinated) were recruited. A demographic questionnaire was completed through interviews. The unvaccinated participants were asked about the reasons for their refusal. The Shapiro-Wilk test, independent t-test, chi-square test, and logistic regression were used for analyzing data. Results: Older people were 1.018 times more likely to refrain from vaccination (95% confidence interval [CI], 1.001–1.039; p=043). People who were manual workers as well as those who were unemployed/housewives were 0.288 and 0.423 times less likely to receive vaccination, respectively. Those with high school education and married women were 0.319 and 0.280 times less likely to receive vaccination, respectively (95% CI, 198–0.515; p<0.001; 95% CI, 0.186–0.422; p<0.001). Participants who had hypertension or suffered from neurological disorders were more likely to receive the vaccination. Finally, people affected with severe COVID-19 infection were 3.157 times more likely to get vaccinated (95% CI, 1.672–5.961; p<0.001). Conclusion The results of this study showed that lower level of education and older age were contributed to reluctance for vaccination, while having chronic diseases or being already infected with severe COVID-19 infection were associated with more acceptance of vaccination.

PURPOSE: Abdominal CT scan using oral and intravenous (IV) contrast is helpful in the diagnosis of intra-abdominal injuries. However, the use of oral and IV contrast delays the process of diagnosis and increases the risk of aspiration. It has also been shown that CT scan with IV contrast alone is as helpful as CT scan with oral and IV contrast and rectal CT scan in detecting abdominal injuries. Therefore, the present study aims to prospectively compare the diagnostic value of CT scan with oral and IV contrast versus CT scan with IV contrast alone in the diagnosis of blunt abdominal trauma (BAT). METHODS: Altogether 123 BAT patients, 60 (48.8%) women and 63 (51.2%) men with the mean age of (40.4 ± 18.7) years who referred to the emergency department of Imam Khomeini Educational and Medical Center in Sari, Iran (a tertiary trauma center in north of Iran) from November 2014 to March 2017 and underwent abdominal CT scans + laparotomy were investigated. Those with penetrating trauma or hemodynamically unstable patients were excluded. The participants were randomly allocated to two groups: abdominal CT scan with oral and IV contrast (n = 63) and CT scan with IV contrast alone (n = 60). No statistically significant difference was found between two groups regarding the hemodynamic parameters, age, gender, injury mechanisms (all p > 0.05). The results of CT scan were compared with that of laparotomy results. The collected data were recorded in SPSS version 22.0 for Windows. Quantitative data were presented as mean and SD. RESULTS: The sensitivity and specificity of CT scan using oral and IV contrast in the diagnosis of BAT were estimated at 96.48 (95% CI: 90.73 - 99.92) and 92.67 (95% CI: 89.65 - 94.88), respectively; while CT scan with IV contrast alone achieved a comparable sensitivity and specificity of 96.6 (95% CI: 87.45 - 99,42 and 92.84 (95% CI: 89.88 - 95.00), respectively. CONCLUSION CT scan with IV contrast alone can be used to assess visceral injuries in BAT patients with normal hemodynamics to avoid diagnostic delay.

This study was conducted to review the efficacy of different sources of stem cells in bone regeneration of cleft palate patients. The majority of previous studies focused on the transplantation of bone marrow mesenchymal stem cells. However, other sources of stem cells have also gained considerable attention, and dental stem cells have shown especially favorable outcomes. Additionally, approaches that apply the co-culture and co-transplantation of stem cells have shown promising results. The use of different types of stem cells, based on their accessibility and efficacy in bone regeneration, is a promising method in cleft palate bone regeneration. In this regard, dental stem cells may be an ideal choice due to their efficacy and accessibility. In conclusion, stem cells, despite the lengthy procedures required for culture and preparation, are a suitable alternative to conventional bone grafting techniques.

Introduction: The quality of healthcare services can be determined by patient satisfaction as it affects the performance, sustainability, and durability of health services. This study aims to determine patients’ satisfaction with healthcare service providers and its determinants in the urban family physician program in Fars and Mazandaran provinces, Iran. Methods: A cross-sectional study was conducted on the populations covered by the urban family physician program in Fars and Mazandaran provinces in 2016. In total, 864 households were selected in each province using random cluster sampling. Socio-demographic variables and underlying factors were gathered. Patient satisfaction levels were evaluated using a validated questionnaire. Results: Of the 1,480 participants with a mean age of 46.9 ± 14.2 years, 53.3% lived in Fars province and 74.2% were female. Furthermore, 67.9% of the patients were satisfied with their healthcare service providers. A higher satisfaction level was observed among the patients who resided in Fars province, lived in cities with <100,000 residents, walked <10 minutes to the family physician’s office, had a family physician they previously knew, accepted the family physician, had a positive attitude towards the importance of having a family physician and a referral system, and had adequate knowledge of the family physician program. Conclusion The results indicated that two-thirds of the patients were satisfied with healthcare service providers. Several socio-demographic variables were associated with the patients’ satisfaction levels. Improving the family physician program by providing adequate medical equipment and monitoring physicians’ performance could increase patient satisfaction and improve the sustainability of the program.

Human adipose stem cells (hASCs) were introduced as appropriate candidate due to advantages like ease of isolation, in vitro expansion and lack of immune response. Deprenyl (Dep) was used to induce bone marrow stem cells into neuron-like cells. We investigated the Dep effect on neurotrophin genes expression in hASCs and their differentiation into neuron-like cells. The cells were isolated from small pieces of abdominal adipose tissue and subjected to flow cytometry to confirm purification. The osteogenic and adipogenic differentiation were identified. The proliferation rate and neurotrophin genes expression of treated cells were evaluated by MTT, TH immunostaining and RT-PCR. hASCs had positive response to CD44, CD73, CD90, CD105 markers and negative response to CD34 and CD45 markers and differentiated into adipocytes and osteocytes. Exposure to 10–7 M of Dep for 24 hours caused a significant increase of viable cells and BDNF, NTF-3 genes expression as compared to cultured cells in serum free medium and had no effect on the expression of NGF and GDNF genes. Based on our results, Dep is able to induce BDNF, NTF-3 and NTF-4 genes expression and neroun-like morphology in hASCs.

Introduction: Sexual satisfaction is one of the important factors in marital satisfaction that affects couples' health and quality of life. The aim of this study was to determine sexual satisfaction and its related factors among married women in Shahroud, northeast of Iran. Methods: This cross-sectional study was conducted in 2017 and 500 married women were evaluated using Larson Sexual Satisfaction Questionnaire. The data were analyzed using chi-square, one-way ANOVA and a multiple regression model. Results: The mean age of the participants was 32.8 (SD= 8.7) years, and the length of the marriage was 11.05 (SD= 9.1). Among the participants, 4.4% (N=22) had low sexual satisfaction; 37.8% (N=189) had moderate satisfaction. The bivariate analysis showed significant relationships between sexual satisfaction and variables including age, husband's age, length of marriage, number of children, education, husband's education and income (p<0.001). The regression analysis also indicated significant relationships between sexual satisfaction and education (P=0.006), length of the marriage (P<0.001) and income (P=0.005). Conclusion: Socio-economic variables such as education and income are among the main factors related to sexual satisfaction. However, counseling couples on sexual issues after marriage can help improve their sexual satisfaction.

Longitudinal data are prevalent in clinical research; due to their correlated nature, special analysis must be used for this type of data. Creatinine is an important marker in predicting end-stage renal disease, and it is recorded longitudinally. This study compared the prediction performance of linear regression (LR), linear mixed-effects model (LMM), least-squares support vector regression (LS-SVR), and mixed-effects least-squares support vector regression (MLS-SVR) methods to predict serum creatinine as a longitudinal outcome.
