Outcomes of COVID-19 in 24 hospitalized liver transplant recipients: an observational study.

BACKGROUND: Although liver transplant (LT) recipients are considered a population at risk of severe features of coronavirus disease 2019 (COVID-19), data in this regard are scarce and controversial. In this study, we reported the outcome of 24 cases of LT recipients who were hospitalized due to COVID-19 and investigated the role-playing factors in the severity of the disease. METHODS: In this single-center, analytic case-series study, eligible patients were among LT recipients who were hospitalized due to the diagnosis of COVID-19 based on positive results of polymerase chain reaction. Participants were categorized as severe COVID-19 if they were admitted to the intensive care unit, experienced respiratory failure demanding mechanical ventilation, or eventually died. Demographic and clinical data, COVID-19 symptoms and specific treatments, laboratory biomarkers, and immunosuppressive regimens and their alteration during the admission were recorded. Analysis was done using SPSS software. RESULTS: Twenty-four hospitalized LT patients were included, of which nine had severe and fifteen had non-severe COVID-19. Out of 9 patients with severe COVID-19, four sadly died. The analysis and comparison between the two groups revealed longer hospital stays (P = 0.02), lower lymphocyte counts (P = 0.002), and higher levels of C-reactive protein (CRP) (P = 0.006) in patients with severe COVID-19. Patients with non-severe COVID-19 had higher doses of tacrolimus and mycophenolate in their baseline immunosuppressive regimen (both P = 0.02). CONCLUSION: Lymphopenia and high CRP levels are associated with more severe forms of COVID-19 in LT patients. Mycophenolate may have protective properties against severe COVID-19. The role of severity indicators in LT patients with COVID-19 needs to be systematically recognized.

Perinatal outcomes and sinopharm BBIBP-CorV vaccination during pregnancy.

BACKGROUND: After the outbreak of COVID-19, a huge part of the health care services was dedicated to preventing and treating this disease. In case of COVID-19 infection, severe COVID-19 is reported more in pregnant individuals. Afterward, Vaccination against SARS-CoV-2 became a hot topic due to known effects in preventing severe COVID-19 during pregnancy. Vaccination of pregnant individuals started in August 2021 with the Sinopharm vaccine in Iran. The aim of current study was to determine the incidence of perinatal outcomes in women who were vaccinated during pregnancy. METHOD: This retrospective cohort study included 129,488 singleton births from March 21, 2021, until March 21, 2022, in Tehran, Iran. The data was obtained from the Iranian Maternal and Neonatal (IMaN) Network and the Maternal Vaccination Registry. Adverse perinatal outcomes investigated in this study include preterm birth, extremely preterm birth, low birth weight, very low birth weight, intrauterine growth restriction, stillbirth, neonatal intensive care unit admission, congenital anomaly, neonatal death and low 5-minute Apgar score. The risk of all perinatal outcomes was evaluated using multiple logistic regression. The analysis was done using STATA version 14. RESULTS: Of all 129,488 singleton births included in this study, 17,485 (13.5%) were vaccinated against SARS-CoV-2 (all with Sinopharm (BBIBP-CorV)). The exposure to the Sinopharm vaccine during pregnancy caused a significant decrease in the incidence of preterm birth (P =0.006, OR=0.91 [95% CI, 0.85 to 0.97]), extremely preterm birth (P =<0.001,OR=0.55 [95% CI, 0.45 to 0.66]), and stillbirth (P =<0.001, OR=0.60 [95% CI, 0.47 to 0.76]). Exposure to vaccination during the first trimester was associated with an increased risk of preterm birth (P =0.01, OR=1.27 [95% CI, 1.04 to 1.55]) Maternal vaccination during pregnancy was not associated with an increased risk of other adverse perinatal outcomes included in this study. CONCLUSION: The finding of this population-based study indicated no adverse pregnancy outcome due to vaccination with the Sinopharm vaccine during the second and third trimesters of pregnancy. Overall risk of adverse pregnancy outcomes were lower in the vaccinated individuals compared to the unvaccinated group. Also, vaccination during the first trimester was associated with an increased risk of preterm birth.

Chemotherapy delays among cancer patients in Iran during COVID-19 pandemic.

BACKGROUND AND OBJECTIVES: Following the outbreak of COVID-19, a set of restrictions, health advice, and limitations were put in place to reduce the spread of the virus. These restrictions, together with fear and anxiety of the population, limited people's access to public services such as health care services. Cancer patients during this era are a significant concern due to being at high risk for COVID-19 infection and also being exposed to delays in their diagnosis, treatment, and follow-ups. Delays in the treatment of cancer could lead to a poorer prognosis. In this study, we attempted to determine the magnitude of delays in chemotherapy and factors associated with delays during the COVID-19 pandemic. METHOD: All patients diagnosed with colorectal, lung, gastric cancer, and lymphoma who had chemotherapy at teaching hospitals of Iran University of Medical Sciences (IUMS) between February 20, 2020, and March 20, 2022, were included. Age, gender, cancer type, having metastatic cancer, and date of each chemotherapy session were included for each patient individually. Every session with delays longer than two days was recorded. A three to six-day delay was considered a moderate delay, and a seven-day or longer delay was considered a severe delay in receiving each chemotherapy session. Additionally, each patient's total number of delays in the entire course was calculated. Logistic regression was used to examine the impact of pandemic waves on delays. On the other hand, Poisson regression was used to evaluate the number of delays in the entire course of chemotherapy. RESULTS: The research findings indicated an association between the male gender and having metastasis with a higher likelihood of a moderate delay in the treatment regimen. Regarding cancer type, colorectal cancer was associated with higher rates of moderate delays (IRR = 1.88, P < 0.001), but gastric (IRR = 0.75, P = 0.001) and lung cancer (IRR = 0.59, P = 0.002) were associated with reduced rates of severe and moderate delays, respectively. Compared to the COVID-19 pandemic plateau periods, the first (OR = 2.08, P < 0.001), third, and fifth waves of the pandemic were associated with increased delays. CONCLUSION: We found an association between the male gender, colorectal cancer, metastatic disease and higher rates of moderate delays. The initial COVID-19 pandemic wave was associated with increased severe delays in the chemotherapy course. According to the findings of this study, male cancer patients and those with metastatic cancer are at risk of poorer prognosis due to lower adherence to treatment. These findings can assist policymakers in developing targeted strategies to lessen the delay rates in the more vulnerable population.

Prevalence of the Patterns of Unhealthy Diet in the School and University Students of Iran: A Systematic Review and Meta-Analysis.

Introduction: The present study was conducted to investigate the pooled prevalence rate of the different patterns of unhealthy diet among the school and university students of Iran. Methods: In this systematic review, the type of the main question was regarding prevalence and the effect measure was prevalence rate reported along with 95% confidence interval (CI). Data bases including PubMed, Scopus, and Web of Science as well as Google Scholar and Persian resources were used. The Newcastle-Ottawa scale (NOS) checklist was used for quality assessment of studies. Results: The extracted types of unhealthy diet in the present systematic review were "breakfast skipper," "fast food," "hydrogenated oils consumption," "salty snacks," "sweetened beverages," "breakfast skipper," "dinner skipper," "launch skipper," and "sweets." The range of pooled prevalence for different types was 0.06-0.75. The data of 16,321 subjects included in six studies were analyzed. The pooled prevalence of unhealthy diet was 0.28 (95% CI: 0.23-0.33, I 2 > 99%) overall, 0.25 (95% CI: 0.20-0.31, I 2 > 99%) in school students and 0.37 (95% CI: 0.12-0.62, I 2 > 99%) in university students. The most prevalent pattern was breakfast skipping 0.39 (95% CI: 0.28-0.50) followed by consumption of sweetened beverages 0.31 (95% CI: 0.20-0.43). The pooled prevalence range among the patterns was 0.06-0.75 (random effects for all). Conclusion: The pooled prevalence was 28% for unhealthy diet among the Iranian students (6% to 75% in different patterns). Although there was uncertainty regarding the pooled evidence, the whole of the mentioned range was clinically important for health policymakers. Decisions should be made on the basis of the patterns.

Prevalence of obsessive-compulsive disorders (OCD) symptoms among health care workers in COVID-19 pandemic: a systematic review and meta-analysis.

BACKGROUND: Obsessive Compulsive Disorder (OCD) symptoms, are among the serious mental health challenges that Health Care Workers (HCWs) faced during the COVID-19 pandemic. As these symptoms reduce the mental well-being and effectiveness of HCWs which are followed by poor health outcomes for patients, the aim of this systematic review and meta-analysis was to determine the prevalence of OCD symptoms among HCWs worldwide. METHODS: PubMed, Google Scholar, Cochrane, Scopus, Web of Science, ProQuest, Emerald, and ERIC databases were searched using related keywords till the end of October 2021. Observational studies about the prevalence of OCD symptoms among healthcare workers during the COVID-19 pandemic were screened and evaluated. In order to assess the quality of studies, the Newcastle-Ottawa scale (NOS) checklist was used. The effect measure was the prevalence rate with a 95% confidence interval (CI). RESULTS: A total of 7864 individuals from 11 studies were included. The range of OCD symptoms prevalence across these studies was from 0.07 to 0.47. Due to the high heterogeneity between the studies (I2 = 98.6%, P < 0.01), the random effects model was used. The pooled prevalence was 0.29 (95% CI: 0.22-0.38) based on logit transformed CI. CONCLUSIONS: The pooled prevalence of OCD symptoms was 29% among the HCWs during the COVID-19 pandemic. This prevalence was higher than the general population according to the pre-pandemic literature, but lower than the recent reports amid the pandemic. Psychosocial interventions are suggested to be designed and implemented in such conditions.

Exploring the attitudes of general medical students toward older adult's care in a lower middle-income country: implications for medical education.

OBJECTIVE: The motivation for this study stemmed from the growing population of older adults and the increasing demand for healthcare professionals who possess the necessary skills and knowledge to provide quality care to this demographic. By exploring the attitudes, perceptions, and beliefs of medical students towards older adult care, the study aimed to identify gaps in their training and areas where improvements can be made to better equip them for this critical aspect of healthcare. METHOD: This study was a qualitative thematic analysis. The participants of this research were selected from among the general medicine internship students of Iran University of Medical Sciences by purposive sampling method. In-depth individual semi-structured interviews were used to collect data. Sampling continued until data saturation. The interviews were recorded, transcribed, and analyzed using a hybrid approach of inductive and deductive thematic analysis. Using this approach, the analysis of the data became more adaptable and open-ended, free from the restrictions of pre-existing theoretical frameworks. MAXQDA 22 was used to analyze qualitative data. RESULTS: A total of 27 medical students were interviewed semi-structured, and audio files were transcribed immediately after the interview. In the process of reading the interviews carefully and separating the conceptual units into codes, 167 primary codes were obtained, and these codes were divided into five main categories under the title of root factors after constant comparison analysis. Five main themes are including discrimination in service delivery, a lack of inter-professional training, interpersonal communication skills, inadequate infrastructure and human resources, and enhancing attitudes towards older person care through experiential learning. CONCLUSION: This study sheds light on the attitudes and perceptions of medical students toward older adult care in a lower-middle-income country. The findings reveal that there are significant gaps in their training and preparation for providing quality care to this demographic profile. The four main categories identified as root factors highlight key areas where improvements can be made in medical education. It is recommended that medical schools in low and middle-income countries consider incorporating these themes into their curricula to better equip future healthcare professionals with the necessary skills and knowledge to provide quality care to older adults.

Risk of permanent medical impairment after road traffic crashes: A systematic review.

PURPOSE: To systematically review the risk of permanent disability related to road traffic injuries (RTIs) and to determine the implications for future research regarding permanent impairment following road traffic crashes. METHODS: We conducted this systematic review according to the preferred reporting items for systematic reviews and meta-analysis statement. An extended search of the literature was carried out in 4 major electronic databases for scientific research papers published from January 1980 to February 2020. Two teams include 2 reviewers each, screened independently the titles/abstracts, and after that, reviewed the full text of the included studies. The quality of the studies was assessed using the strengthening the reporting of observational studies in epidemiology (STROBE) checklist. A third reviewer was assessed any discrepancy and all data of included studies were extracted. Finally, the data were systematically analyzed, and the related data were interpreted. RESULTS: Five out of 16 studies were evaluated as high-quality according to the STROBE checklist. Fifteen studies ranked the initial injuries according to the abbreviated injury scale 2005. Five studies reported the total risk of permanent medical impairment following RTIs which varied from 2% to 23% for car occupants and 2.8% to 46% for cyclists. Seven studies reported the risk of permanent medical impairment of the different body regions. Eleven studies stated the most common body region to develop permanent impairment, of which 6 studies demonstrated that injuries of the cervical spine and neck were at the highest risk of becoming permanent injured. CONCLUSION: The finding of this review revealed the necessity of providing a globally validated method to evaluate permanent medical impairment following RTIs across the world. This would facilitate decision-making about traffic injuries and efficient management to reduce the financial and psychological burdens for individuals and communities.

The Effects of Covid-19 on Financial-Economic and Performance Efficiency of Hospitals.

Background: During the pandemic of COVID-19, the function and performance of hospitals have been affected by various economic-financial and management aspects. The aim of the current study was to assess the process of therapeutic care delivery and also the economic-financial functions of the selected hospitals before and after COVID-19. Methods: This research is a descriptive-analytical study and a cross-sectional-comparative study in terms of time, and it was conducted in several selected teaching hospitals of Iran University of Medical Sciences. A purposeful and convenient sampling method was used. The data has been collected using the standard research tool (standard checklist of the Ministry of Health) in the two areas of financial-economic and healthcare performance (such as Data of financial and economic indicators such as direct and indirect costs, liquidity ratio and profitability index as well as key performance indicators of hospitals such as bed occupancy ratio (BOR; %), average length of stay (ALOS), bed turnover rate (BTR), bed turnover distance rate (BTIR) and hospital mortality rate (HMR), physician-to-bed ratio and nurse-to-bed ratio) of hospitals in two times before and after the outbreak of COVID-19 (time period 2018 to 2021). The data was collected from 2018 to 2021. Pearson/Spearman regression was used for the evaluation of the relationship between variables using SPSS 22. Results: This research showed the admission of COVID-19 patients caused a change in the indicators we evaluated. ALOS (-6.6%), BTIR (-40.7%), and discharge against medical advice (-7.0%) decreased from 2018 to 2021. BOR; % (+5.0%), occupy bed days (+6.6%), BTR (+27.5%, HMR (+50%), number of inpatients (+18.8%), number of discharges (+13.1%), number of surgeries (+27.4%), nurse-per-bed ratio (+35.9%), doctor-per-bed ratio (+31.0%) increased in the same period of time. The profitability index was correlated to all of the performance indicators except for the net death rate. Higher length of stay and turnover interval had a negative effect on the profitability index while higher bed turnover rate, bed occupancy ratio, bed day, number of inpatient admission, and number of surgery had a positive effect on the profitability index. Conclusion: It has been shown from the beginning of the COVID-19 pandemic, the performance indicators of the studied hospitals were negatively affected. As a consequence of the COVID-19 epidemic, many hospitals were not able to deal with the negative financial and medical outcomes of this crisis due to a significant decrease in income and a double increase in expenses.

Adverse effects following COVID-19 vaccination in Iran.

BACKGROUND: Vaccination is a key intervention to prevent COVID-19. Many vaccines are administered globally, yet there is not much evidence regarding their safety and adverse effects. Iran also faces this challenge, especially as data regarding the Sputnik V vaccine is sparse. Therefore, the aim of this study is to determine the adverse effects of the most commonly used vaccines in Iran. METHODS: Using a retrospective cohort study design, 6600 subjects aged 18 years or older who had received two doses of any of the three COVID-19 vaccines (Sinopharm, AstraZeneca, and Sputnik V) were selected using a random sampling method between March and August 2021. Subjects were asked about any adverse effects of the vaccines by trained interviewers via telephone interview. Vaccine-related adverse effects in individuals during the first 72 h and subsequently following both doses of the vaccines were determined. The demographic variables, type of administered vaccine, adverse effects, and history of the previous infection with COVID-19 were collected. Descriptive statistics (mean, standard deviation) and analytical statistics (Chi-squared and Wilcoxon tests) were performed at a 95% significance level using STATA software version 15 (STATA Corp, College Station, TX, USA). RESULTS: From 6600 participants, 4775 responded (response rate = 72.3%). Of the participants, 1460 (30.6%) received the AstraZeneca vaccine, 1564 (32.8%) received the Sinopharm vaccine and 1751 (36.7%) received the Sputnik V vaccine. 2653 participants (55.56%) reported adverse effects after the first dose and 1704 (35.7%) after the second dose. Sputnik V caused the most adverse effects with 1449 (82.7%) vaccine recipients reporting symptoms after the first or second dose, compared with 1030 (70.5%) for AstraZeneca and only 585 (37.4%) for the Sinopharm vaccine. The most common adverse effects after the first dose were fatigue (28.37%), chill/fever (26.86%), and skeletal pain (22.38%). These three adverse effects were the same for the second dose, although their prevalence was lower. CONCLUSIONS: In this study, we demonstrate that the Sputnik V vaccine has the highest rate of adverse effects, followed by the AstraZeneca and Sinopharm vaccines. COVID-19 vaccines used in Iran are safe and there were no reports of serious adverse effects.

COVID-19 in Iran: What was done and what should be done.

The current COVID-19 pandemic started in Wuhan, China, in December 2019. The World health Organization (WHO) declared the COVID-19 as a public health emergency of international concern on January 30, 2020, and recognized the situation as a pandemic on March 11, 2020. Around 135 million confirmed cases and around 2.9 million deaths until the first week of April 2021 have been among its direct impacts on human health. All countries have been affected in different degrees, and each of them has used different strategies to protect themselves against health and nonhealth consequences of this epidemic. Although all approaches are full of mistakes with fatal and painful results, some of them were successful in limiting the epidemic. One of the astonishing improvements is development of several vaccines in a relatively short period of time, which has increased hopes for epidemic control. This review aims to critically appraise the strategies for COVID-19 epidemic control in Iran since the beginning of the disease until the fourth peak of disease in March 2021.

The relationship between dietary patterns, dietary quality index, and dietary inflammatory index with the risk of all types of cancer: Golestan cohort study.

Background: Dietary patterns and diet quality index (DQI) are widely discussed in relation with different health conditions and have recently been taken into consideration for all cancer types. Since chronic inflammation has been recognized as an important biologic risk factor for cancer occurrence, especially in epithelial tissues, proinflammatory or anti-inflammatory characteristics of diet has become the center of attention. In the present study, we aimed to identify whether a specific dietary pattern, Mediterranean dietary score (MDs), and dietary inflammatory index (DII) were associated with overall cancer risk in Iranian population. Methods: This study was performed in the context of the Golestan cohort study. Participants with extreme daily energy intake or those who did not answer more than 30 question of the Food Frequency questionnaire (FFQ) were excluded. Dietary patterns, MDs, and DII were measured from FFQ. Age, sex, total energy, place of residence, smoking, wealth score, ethnicity, opiate use, BMI, education, marital status, and physical activity score were considered as confounding variables. Using Cox proportional hazards regression models, hazard ratios (HRs) and 95% confidence interval of cancer were estimated. Results: HRs (95% CIs) of all cancers by quartiles of Western dietary pattern, DII, and MDs showed that the forth quartile of the Western dietary pattern is attributed to 23% higher cancer risk (HRs: 1.23, CI: 1.09-1.40, P< 0.001, adjusted for age and sex) compared to the first quartile. It also remained significant after further adjustments (HRs = 1.20, CI: 1.06-1.36, P< 0.001). There was a higher cancer risk in the fourth quartile of DII in comparison with the first quartile (HRs = 1.16, CI: 1.01-1.32, P trend < 0.001, adjusted for age and sex). The lower adherence to the Mediterranean dietary pattern also largely contributes to 27% higher cancer risk (HRs: 1.27, CI: 1.12-1.44), P trend < 0.001, adjusted for age and sex), which also remained remarkable after further adjustments ((HRs =1.19, CI: 1.05-1.35, P trend < 0.001). Conclusion: Cancer is highly correlated to dietary intake and dietary patterns, such as the Western dietary pattern, while the Mediterranean diet score was inversely associated with cancer risk. Further investigations are required to get a broader insight into cancer determinants in population.

Evaluating the impact of results-based motivating system on noncommunicable diseases risk factors in Iran: Study protocol for a field trial.

Background: Risk factors of noncommunicable diseases (NCD) are increasingly contributing to morbidity and mortality in Iran. Health care providers' competencies and motivation are essential factors for the success and efficiency of primary health care. This field trial aims to evaluate the impact of a results-based motivating system on population level of the NCD risk factors field trial (IRPONT) in Iran. Methods: Population groups of 24 rural or urban catchment areas from 3 provinces were randomized to 1 of the 4 types of study groups. The groups were defined based on a set of 4 intervention packages. Extra 8 rural or urban catchment areas in a separate city were considered as independent nonintervention (control) group. Population levels of major NCD risk factors in all 32 population groups were measured at the beginning of the trial, at the end of the first year, and will be measured in the second year through standardized population surveys. As the outcome measure, the difference in population levels of the risk factors will be compared among the study groups. Study group IV will be compared with combined control groups (study groups I, II, and III). Also, we will conduct subgroup analysis to determine the effects of interventions 2, 3, and 4. Ethics: This trial has received ethical approval from National Institute for Medical Research Development in Iran (IR.NIMAD.REC.1396.084) in 2017. Trial Registration Number: This trial has been registered on the Iranian Registry of Clinical Trials (identifier: IRCT20081205001488N2). Registered on 3 June 2018 and updated on 12 April 2020.

Effect of Arbidol (Umifenovir) on COVID-19: a randomized controlled trial.

BACKGROUND: Treatment of patients with COVID-19 has included supportive care to mainly relief symptoms of the disease. Although World Health Organization (WHO) has not recommended any effective treatments for COVID-19, there are some reports about use of antiviral drugs. The aim of this study is to determine the effect of Arbidol (ARB) on COVID-19 disease. METHODS: Using an open-label randomized controlled trial, we examined the efficacy of ARB in patients with COVID-19 in a teaching hospital. One hundred eligible patients with diagnosis of COVID-19 were recruited in the study and assigned randomly to two groups of either hydroxychloroquine followed by KALETRA (Lopinavir/ritonavir) or hydroxychloroquine followed by ARB. The primary outcome was hospitalization duration and clinical improvement 7 days after admission. The criteria of improvement were relief of cough, dyspnea, and fever. Time to relief from fever was also assessed across the two groups. Without any dropouts, 100 patients were entered into the study for the final analysis at significance level of 0.05. RESULTS: The mean age of patients was 56.6 (17.8) years and 56.2 (14.8) years in ARB and KALETRA groups, respectively. Majority of patients were male across two groups (66 and 54%). The duration of hospitalization in ARB group was significantly less than KALETRA arm (7.2 versus 9.6 days; P = 0.02). Time to relief fever was almost similar across two groups (2.7 versus 3.1 days in ARB and KALETRA arms, respectively). Peripheral oxygen saturation rate was significantly different after 7 days of admission across two groups (94% versus 92% in ARB and KALETRA groups respectively) (P = 0.02). Based on multiple linear regression analysis, IHD, Na level, and oxygen saturation at the time of admission and type of therapy were the independent adjusted variables that determined the duration of hospitalization in patients with COVID-19. CONCLUSION: Our findings showed that Arbidol, compared to KALETRA, significantly contributes to clinical and laboratory improvements, including peripheral oxygen saturation, requiring ICU admissions, duration of hospitalization, chest CT involvements, WBC, and ESR. We suggest further studies on ARB against COVID-19 using larger sample size and multicenter design. TRIAL REGISTRATION: IRCT20180725040596N2 on 18 April 2020.

Prevalence and Socio-Demographic Correlates of Mental Health Problems Among Iranian Health Sciences Students.

OBJECTIVE: The primary objective of the present study was to compare the mental health status of Iranian medical vs other health sciences students and to examine how demographic factors relate to their mental health problems. METHODS: A total of 560 medical and other health sciences students (250 (44.6%) males and 310 (55.4%) females) were recruited from Iran University of Medical Sciences. Data were obtained by self-administered questionnaire, including questions on socio-demographic characteristics. The Beck Depression Inventory, Beck Anxiety Inventory, General Health Questionnaire, and WHO well-being index were used to assess mental health status of students. RESULTS: Ten percent of students had BDI scores consistent with clinically significant depression (6.6% mild, 1.8% moderate, 1.6% severe), and 28.7% had BAI scores consistent with clinically significant anxiety (20.7% mild, 7.1% moderate, 0.9% severe). Kurdish students had an odds ratio (OR) of 2.71 (95% CL, 1.22-6.02) for mild to severe depression symptoms when compared to Persian students. The prevalence of distressed health sciences students and poor psychological well-being was 13.4% and 14.1%, respectively. Maternal education gave an OR of 0.57 (0.35-0.93) for anxiety symptoms, after adjustment for all other factors. The possibility of general psychiatric morbidity was significantly lower in students who studied medicine (OR, 0.40 (0.21-0.71)). Being born in the capital city was associated with better psychological well-being (OR, 0.48 (0.26-0.86)). CONCLUSIONS: Ethnicity, birthplace, discipline, and maternal educational level were major determinants of mental health status among health sciences students. Further research should be undertaken to determine the prevalence of psychological disorders using more reliable diagnostic interview.

Unintended pregnancies in Hamedan, Iran: Levels and determinants.

The recent limitation in the provision of publicly funded family planning services in Iran has concerned stakeholders in reproductive health about the incidence of unintended pregnancies. This study used data from Hamedan Survey of Fertility (HSF), conducted in April-June 2015 among a representative sample of 3,000 married women aged 15-49 years living in the city of Hamedan (Iran), to estimate levels of unintended pregnancies and examine factors related to pregnancy intentions for the most recent birth, using multinomial logistic regression analyses. Results showed that 23 percent of pregnant women reported their pregnancy as unintended (17 percent mistimed and 6 percent unwanted). Moreover, unintended pregnancies in the five years preceding the survey were the result of failures of withdrawal (35 percent) and of modern contraceptive use (33 percent), along with contraceptive discontinuation (23 percent) and non-use (9 percent). Multivariate results indicated that the risk of unintended pregnancy was lower among women reporting modern contraceptive failures and lower among those reporting contraceptive discontinuation and non-use, compared with women experiencing withdrawal failures. The high incidence of unintended pregnancies among women experiencing contraceptive failures and discontinuation imply their high unmet need for contraceptive knowledge and counseling rather than for access to contraceptive methods.

Traumatic optic neuropathy treatment trial (TONTT): open label, phase 3, multicenter, semi-experimental trial.

PURPOSE: Intravenously administered erythropoietin (EPO) was firstly commenced (phase 1) in patients with indirect traumatic optic neuropathy (TON) by this group in 2011. It was re-tested by another group (phase 2) in 2014. This multicenter clinical trial was designed to compare its effect with intravenous steroid and observation. METHODS: Included were TON patients ≥5 years of age and with trauma-treatment interval of ≤3 weeks. Follow-up visits were set at 1, 2, 3, 7, 14, 30, and at least 90 days after treatment. EPO and methylprednisolone were infused intravenously every day for three consecutive days. Primary outcome measure was change in the best corrected visual acuity (BCVA). Secondary outcomes included change in color vision and relative afferent pupillary defect (RAPD), side effects, and factors affecting the final visual improvement. RESULTS: Out of 120 patients, 100 (EPO: 69, steroid: 15, observation: 16) were finally included. All three groups showed a significant improvement of BCVA which was not significantly different between the groups (adjusted for pretreatment BCVA). Color vision was significantly improved in the EPO group. Late treatment (>3 days) (odds ratio = 2.53) and initial BCVA of NLP (odds ratio = 5.74) significantly worsened visual recovery. No side effect was observed in any group. CONCLUSION: EPO, steroid, and observation showed a significant improvement of BCVA in patients with TON. Initial BCVA of NLP and late treatment (>3 days) were significant risk factors for visual improvement.

PROLONGED BIRTH INTERVALS IN HAMEDAN, IRAN: VARIATIONS AND DETERMINANTS.

The enduring sub-replacement level of fertility in Iran is the result of changing timing of births. Using data from the 2015 Hamedan Survey of Fertility, conducted in a representative sample of 3000 married women aged 15-49, this study examined variations in median lengths of birth intervals employing cumulative survival functions, and investigated the determinants of birth interval lengths using regression hazard models. The results showed that the median first, second and third birth intervals, estimated at 28, 74 and 136 months respectively, doubled between 1995 and 2015. The multivariate analysis results indicated the strong impact of contraceptive use and higher education on lengthening birth intervals, with greater effects on the timing of second and third births. The relative risks of second and third births were higher among rural migrants, unemployed women and those with shorter periods of breast-feeding and the death of a preceding birth. Only timing of the third birth was influenced by son preference. The implications of the results for low fertility and maternal and child health in Iran are discussed.

The Characteristics of Excimer Laser Refractive Surgery Candidates.

PURPOSE: To determine the demographic and refractive characteristics of excimer laser refractive surgery candidates in Iran. METHODS: This was a cross-sectional study between 2010 and 2014. All information was collected from 28 centers randomly selected from 12 provinces. Then, for each season of the year, one week was chosen through simple random selection, and within each week, 3 days were again chosen randomly. All excimer laser surgical procedures performed during these 3 days were identified by training staff, and data were extracted from patient charts. RESULTS: A total of 14,569 charts were reviewed; 67.5% of the subjects were female and the rest were male. Of the total surgeries, 18.6% had been done in 2010 which reached to 19.1% in 2014. The mean age of people receiving refractive surgery showed an upward trend (P<0.001) and female patients were significantly younger than male patients (P<0.001). The 25 to 39 years age group received the highest number of surgeries (31.9% of the total) and there was a significant association with gender (P<0.001). The most common refractive error was compound myopic astigmatism with a prevalence of 79.3%. In 2010, 33.3% of the performed surgeries were covered by insurance policies, and this decreased to 30.2% in 2014 (P<0.001). CONCLUSION: Women with compound myopic astigmatism in the age range of 25 and 35 years are the most frequent users of excimer laser refractive surgery. Less than one-third of laser refractive surgeries are covered by insurance policies. Therefore, proper planning for improving services to this group must be given priority.

Validation of the Persian Version of Spiritual Well-Being Questionnaires.

BACKGROUND: Spiritual well-being is an important issue in health sciences, hence the need for validated instruments to assess this aspect of health in the Iranian population. The aim of the current study was to determine the validity of the Persian versions of 2 most common measures of spiritual health (Spiritual Well-Being Questionnaire [SWBQ] or Spiritual Health and Life-Orientation Measure [SHALOM] and Spiritual Well-Being Scale [SWBS]). METHODS: This was a cross-sectional study via a convenience sampling method in Iran University of Medical Sciences with 170 participants aged above 18 years comprising students, teachers, and administrative staff and managers. The study was conducted from September 7, 2014 to September 20, 2015 in Tehran. Four questionnaires, namely the SWBQ, SWBS, General Health Questionnaire (GHQ-12), and Oxford Happiness Questionnaire (OHQ), were used. Statistical analysis was done using SPSS 18 and LISREL (version 8.2). Cronbach's alpha, intra-class correlation coefficient, Pearson correlation, and confirmatory factor analysis were employed to assess the validity and reliability of the questionnaires. RESULTS: Cronbach's alpha for the SWBQ and the SWBS was greater than 0.85. The repeatability of both questionnaires was between 0.88 and 0.98. The Pearson correlation for the SWBQ and the SWBS ranged from 0.33 to 0.53; and all the correlations were significant. The respondents who indicated a higher spiritual well-being also reported better general health and happiness. CONCLUSION: The Persian versions of the SWBS and the SWBQ have good reliability, repeatability, and validity to assess spiritual health in the Iranian population.

Delivering clinical preventive services in the Islamic Republic of Iran: A model for screening and behavior consultation practices.

Background: Screening and behavior consultation are considered to be limited, dispersed and expensive services across the country. To deliver efficient and equitable services current disordered practices need to be consolidated. Methods: An analysis of current situation, learned lessons and future scopes of country's preventive care delivery, along with a review of international experience and generous participation of various stakeholders, led to proposing a model for screening and behavior consultation practices in IR. Iran. Results: Upon the results of the previous steps, the desired model was based on the network system and family physician. Comprehensive health centers and other centers affiliated to the network are the most appropriate service positions. However, private and academic preventive centers are playing their rules. Conclusion: The proposed model matches the overall pattern of service delivery in the health system (network system with the private sector and the educational sector).
