RESUMO
WHAT IS KNOWN AND OBJECTIVE: Major depressive disorder (MDD) is a complex disease and one of the leading contributors to disease burden throughout the world. In the current study, we explored the efficacy and tolerability of vortioxetine versus sertraline on symptoms of depression in elderly patients with MDD. METHODS: Sixty patients diagnosed with MDD (based on DSM-5) and Hamilton Depression Rating Scale (HAM-D) score ≥ 19 were entered into a randomized double-blind study and were randomized to receive either vortioxetine (15 mg daily) or sertraline (75 mg daily) for six weeks. Patients were assessed using the HAM-D scale at baseline and weeks 3 and 6. Changes in HAM-D score, response rates, remission rate and time to response or remission were also compared between the two study groups. RESULTS AND DISCUSSION: Fifty patients completed the trial after six weeks. General linear model repeated measures demonstrated no difference in trend of the two treatment groups (P = .897). There was no significantly different improvement in the HDRS scores from baseline to weeks 3 and 6, as well. Differences in response rate, remission rate, time to response and time to remission periods were not statistically significant. Finally, there was not any significantly difference between the two study groups in the frequency of adverse events. WHAT IS NEW AND CONCLUSION: This study showed no significant differences in the efficacy and safety of vortioxetine in comparison with sertraline in order for it to be used safely for treatment of major depressive disorder in elderly patients.

Background: Neck pain is a complex musculoskeletal disorder that can result in substantial morbidity. The present article presents the neck pain burden in Iranians who were at least 70 years old, from 1990 to 2019, by sex, age group, and province. Methods: Publicly available information on the prevalence, incidence, and years lived with disability (YLD) caused by neck pain was extracted from the Global Burden of Disease study 2019. The estimates were all provided as counts and age-standardized rates (per 100,000), and included 95% uncertainty intervals. Results: The point prevalence of neck pain in 2019 was 8710.6, while the incidence rate was 1334.7 per 100,000 population. That same year, there were number of 27.8 thousand YLDs and an YLD rate of 801.7 per 100,000. The prevalence, incidence, and YLD rates did not change substantially over the measurement period (1990-2019). The highest YLD rate was found in Tehran (960.9 per 100,000), while Kohgiluyeh and Boyer-Ahmad had the lowest (730.5 per 100,000). Females had slightly higher prevalent cases, incident cases, and YLDs, as well as their corresponding rates in 2019. In 2019, the number of prevalent cases, incident cases, and YLDs peaked in the 70-74 age group, for both sexes, and in all cases they reduced with age. In both 1990 and 2019, Iran had a higher YLD rate than that found among elderly adults in the Middle East and North Africa region. Conclusions: The burden of neck pain in Iran has decreased slightly over the last three decades, but it still imposes a substantial burden and is higher than that found in the rest of the region. Therefore, preventive programs should be initiated at a young age to reduce the attributable burden later in life.
RESUMO
Background: Concerns about the role of chronically used medications in the clinical outcomes of the coronavirus disease 2019 (COVID-19) have remarkable potential for the breakdown of non-communicable diseases (NCDs) management by imposing ambivalence toward medication continuation. This study aimed to investigate the association of single or combinations of chronically used medications in NCDs with clinical outcomes of COVID-19. Methods: This retrospective study was conducted on the intersection of two databases, the Iranian COVID-19 registry and Iran Health Insurance Organization. The primary outcome was death due to COVID-19 hospitalization, and secondary outcomes included length of hospital stay, Intensive Care Unit (ICU) admission, and ventilation therapy. The Anatomical Therapeutic Chemical (ATC) classification system was used for medication grouping. The frequent pattern growth algorithm was utilized to investigate the effect of medication combinations on COVID-19 outcomes. Findings: Aspirin with chronic use in 10.8% of hospitalized COVID-19 patients was the most frequently used medication, followed by Atorvastatin (9.2%) and Losartan (8.0%). Adrenergics in combination with corticosteroids inhalants (ACIs) with an odds ratio (OR) of 0.79 (95% confidence interval: 0.68-0.92) were the most associated medications with less chance of ventilation therapy. Oxicams had the least OR of 0.80 (0.73-0.87) for COVID-19 death, followed by ACIs [0.85 (0.77-0.95)] and Biguanides [0.86 (0.82-0.91)]. Conclusion: The chronic use of most frequently used medications for NCDs management was not associated with poor COVID-19 outcomes. Thus, when indicated, physicians need to discourage patients with NCDs from discontinuing their medications for fear of possible adverse effects on COVID-19 prognosis.

BACKGROUND: We aimed to estimate the prevalence of physical inactivity in all districts of Iran and the disparities between subgroups defined by various measures. METHODS: Small area estimation method was employed to estimate the prevalence of physical inactivity in districts based on the remaining districts in which data on the level of physical inactivity were available. Various comparisons on the estimations were done based on socioeconomic, sex, and geographical stratifications to determine the disparities of physical inactivity among districts of Iran. RESULTS: All districts of Iran had a higher prevalence of physical inactivity compared with the world average. The estimated prevalence of physical inactivity among all men in all districts was 46.8% (95% uncertainty interval, 45.9%-47.7%). The highest and lowest estimated disparity ratio of physical inactivity were 1.95 and 1.14 in males, and 2.25 and 1.09 in females, respectively. Females significantly had a higher prevalence of 63.5% (62.7%-64.3%). Among both sexes, the poor population and urban residents significantly had higher prevalence of physical inactivity than rich population and rural residents, respectively. CONCLUSIONS: The high prevalence of physical inactivity among Iranian adult population suggests the urgent need to adopt population-wide action plans and policies to handle this major public health problem and avert the probable burden.

Context: The immune system is directly linked to the tumors, from tumor formation to the tumor's development and metastasis. So, the interest of scientists over the protective immunological mechanisms has increased and shown gifted strategy in cancer treatment. Evidence acquisition: Genetic engineering and cellular immunotherapy are two different advanced molecular mechanisms to modify the immune responses and genome. Gene manipulation is the bioengineering technology that allows vectors to transfer new genetic information into the target cells. Cellular immunotherapy is an excellent strategy that connects the body's immune system to fight cancer. Results & Conclusions: This review described that combination of genetic engineering and cellular immunotherapy has brought the novel antitumor repressive molecules stopping the tumor tissue immune tolerance and significantly expanding cancer therapy's effectiveness. Usually, cell immunotherapy and genetic engineering are considered two independent processes, and, in this review, we believe them in combinations. Here, we review these two novel approaches, and they are both combinations in terms of technological advances and clinical experience.
RESUMO
BACKGROUND: Colorectal cancer (CRC) is among the five most incident and lethal cancers in world and its burden varies between countries and sexes. We aimed to present a comprehensive measure called the quality of care index (QCI) to evaluate the inequity and healthcare quality of care regarding CRC by sex and location. METHODS: Data on the burden of CRC were extracted from the Global Burden of Disease study 2019. It was transformed to four ratios, including mortality-to-incidence, disability-adjusted life years (DALYs)-to-prevalence, prevalence-to-incidence, and years of life lost (YLLs)-to-years lived with disability (YLDs). Principal component analysis was implemented on the four ratios and the most influential component was considered as QCI with a score ranging from zero to 100, for which higher scores represented better quality of care. Gender Disparity Ratio (GDR) was calculated by dividing QCI for females by males. RESULTS: The global incidence and death numbers of CRC were 2,166,168 (95% uncertainty interval: 1,996,298-2,342,842) and 1,085,797 (1,002,795-1,149,679) in 2019, respectively. Globally, QCI and GDR values were 77.6 and 1.0 respectively in 2019. There was a positive association between the level of quality of care and socio-demographic index (SDI) quintiles. Region of the Americas and African Region had the highest and lowest QCI values, respectively (84.4 vs. 23.6). The QCI values started decreasing beyond the age of 75 in 2019 worldwide. CONCLUSION: There is heterogeneity in QCI between SDI quintiles. More attention should be paid to people aged more than 75 years old because of the lower quality of care in this group.

Background: Ischemic Heart Diseases (IHDs) are the main causes of deaths all over the world. Since there is no comprehensive study on IHDs mortality rate in Iran, the present study aimed to estimate age-standardized IHDs mortality rate by sex, age, geography, and time trends at both national and sub-national levels in Iran. Methods: We used the Death Registration System (DRS) data from 1990 to 2015 collected by the Iranian Ministry of Health and Medical Education across the country, Tehran, and Isfahan main cemetery, not included in the DRS. Utilized death distribution methods to overcome the incompleteness of data. Statistical models including Spatio-temporal and Gaussian-Process Regression models were used to extrapolate all-cause and cause-specific mortality rates. Results: Age-standardized IHDs mortality rate in Iran almost doubled from 1990 to 2015. Forty-nine deaths per 100.000 population in 1990, which increased to 91.6 deaths per 100.000 in 2015). Male to female age-standardized mortality rate increased from 1.07 to 1.32 during the studied period. Aging was associated with an increase in age-standardized IHDs mortality rate in both sexes, all provinces, and all of the years. The range of age-standardized IHDs mortality rate for both sexes was from 58 to 136.2 deaths per 100,000 across provinces in 2015. Conclusion: Due to the increase in age-standardized IHDs mortality rate in Iran, it seems necessary to design and implement appropriate public health interventions by health authorities to prevent and control this group of diseases.
RESUMO
BACKGROUND: Lung cancer is one of the leading cancers, with a high burden worldwide. As a developing country, Iran is facing with population growth, widespread tobacco use, demographic and epidemiologic changes, and environmental exposures, which lead to cancers becoming a severe concern of public health in Iran. We aimed to examine the burden of lung cancer and its risk factors in Iran. METHODS: We utilized the Global Burden of Disease 2019 data and analyzed the total burden of the lung cancer and seven related risk factors by sex, age at national and sub-national levels from 1990 to 2019. RESULTS: The lung cancer age-standardized death rate increased from 11.8 (95% Uncertainty Interval: 9.7-14.4) to 12.9 (11.9-13.9) per 100,000 between 1990 and 2019. This increase was among women from 5 (4.2-7.1) to 8 (7.2-8.8) per 100,000; in contrast, there was a decline among men from 18.5 (14.8-22.6) to 17.8 (16.2-19.4) per 100,000. The burden of lung cancer is concentrated in the advanced age groups. Smoking with 53.5% of total attributable deaths (51.0%-55.9%) was the leading risk factor. At the provincial level, there was a wide range between the lowest and highest, from 8.3 (7.0-10.0) to 19.1 (16.4-22.0) per 100,000 population in the incidence rate and from 8.7 (7.3-10.3) to 20.6 (17.7-24.0) per 100,000 population in mortality rate, respectively in Tehran and West Azerbaijan provinces in 2019. CONCLUSION: The increasing trend of lung cancer burden among the entire Iranian population, the inter-provincial disparities, and the significant rise in burden of this cancer in women necessitate the urgent implementation and development of policies to prevent and manage lung cancer burden and strategies to reduce exposure to risk factors.

Introduction: Atherosclerosis and related cardiovascular diseases (CVDs) are the major causes of mortality worldwide. The available reports regarding the effects of selenium (Se) supplementation in the realm of atherosclerosis have been equivocal. The present investigation is aimed to assess the effects of sodium selenite and Se-enriched yeast supplementation on metabolic parameters among atherosclerotic patients. Methods: In this double-blind placebo-controlled randomized clinical trial, 60 patients diagnosed with atherosclerosis were randomly allocated into either 200 µg/day selenite, yeast, or placebo groups for eight consecutive weeks. Serum levels of lipid profile and glycemic indices were measured at the baseline and end of the intervention. Results: There were no significant within-or between-group changes in levels of total cholesterol, triglycerides, high-density lipoprotein cholesterol (HDL-c), fasting blood sugar, insulin, and homeostatic model assessment for IR throughout the study (P ≥0.05). Only the low density lipoprotein cholesterol (LDL-c) levels were significantly lower in the yeast group in comparison with the placebo group (P = 0.015). Conclusion: The administration of Se-enriched yeast is significantly effective in decreasing LDL-c levels in patients with atherosclerosis. Additional clinical trial studies investigating the effect of Se administration on glucose homeostasis parameters and lipid profiles in atherosclerotic patients are suggested for a more definitive conclusion.
RESUMO
BACKGROUND: Iran lacks a population level comprehensive assessment of stroke epidemiology. Using data from the NASBOD Study, we estimated the mortality of stroke among the Iranian population from 1990 to 2015. METHODS: Data were collected from all the available sources including the national death registration system and two major cemeteries. After addressing incompleteness of child and adult death data and by using mixed effect model, spatio-temporal model and Gaussian Process Regression, levels and trends of child and adult mortality were estimated. By considering cause fraction to these estimates; cause specific mortality was estimated. In these process wealth index, urbanization, and years of schooling were used as covariates. RESULTS: In 2015, the age-standardized stroke mortality rate due was 47.76 (95% UI: 34.68-65.03) for males and 40.16 (30.38-5 2.72) for females, per 100,000 population. Stroke occurrence for both ischemic and non-ischemic strokes showed decreasing trends in both sexes after 2001-2002, at national and sub-national levels. The highest and lowest mortality rates between provinces ranged from 52.11 (40.3-66.66) to 24.47 (18.71-31.79) in men and from 65.51 (47.13-89.41) to 30.43 (21.95-41.82) in women per 100,000 population. CONCLUSION: Although age-standardized rates of stroke mortality are falling, in the past three decades, the absolute number of people who have had a stroke has increased. Stroke mortality remains high in Iran.

BACKGROUND: Cancer, a common disease in adulthood, is a rare albeit slowly increasing condition among children. Currently, limited data are available on the incidence, prevalence, and mortality of these diseases in many regions, including developing countries. Herein, we are reporting national and sub-national estimates on deaths due to childhood cancers between 2000 and 2015 in Iran. METHODS: Cancer mortality rates were estimated using the national death registration system's data after addressing its incompleteness and misclassification, using demographic (complete birth history and summary birth history) and statistical analysis (spatiotemporal, Gaussian process regression, and generalized linear mixed models). We included data from cemeteries of two cities (Tehran and Isfahan) that were not included in the death registration system. We used census data and household expenditure and income surveys for data on population and other covariates used in the modeling. RESULTS: The overall age-standardized death rate (ASDR) of childhood cancers have decreased by 69.52% (80.67-49.71) in Iran (equal to an annual percent change of -3.63 [-4.53- -2.24]), declining from 12.24 (95% UI: 10.52-14.49) in 2000 to 3.73 (2.8-5.29) deaths per 100000 in 2015. This decrement was equal to an annual percent change of 4.35% over these years. Leukemia, brain, and nervous system malignancies accounted for about 66% of all cancer-related mortalities among children and adolescents in 2015, which had a 10% increase compared to 2000. Moreover, trends at the sub-national level showed that the highest and lowest ASDR of childhood cancers ranged from 2.12 to 4.99 across provinces of Iran in 2015. CONCLUSION: Although the overall mortalities have decreased, there is still inequality in the distribution of the recorded deaths. This inequality should be addressed with the improvement of the quality of care and better access to pediatric hospitals and oncologists in these areas.

PURPOSE: To study trends of urological cancers mortalities in Iran between 1990 and 2015 as a part of a larger project named national and subnational burden of diseases, injuries, and risk factors. METHODS: The primary dataset of this project comprises data of national death registration system. Cause-specific mortality fraction for each age, sex, province, and year group was calculated using a two-stage mixed effects and spatiotemporal models, and then these fractions were applied to all-cause mortality rates, obtained from a parallel study to estimate mortality rates attributable to each cause. RESULTS: In 2015, urological cancers constituted 8% of cancer-related deaths in Iran, and number of deaths due to prostate, bladder, testicular, and kidney and other urinary organs cancers were estimated as 2,128 (1,565-2,891), 297 (230-385), 301 (144-639), and 195 (143-267), respectively. Our estimates show that age-standardized death rates (ASDRs) of these cancers reached 6.8 (5-9.23), 0.47 (0.37-0.61), 0.96 (0.46-2.04), and 0.24 (0.18-0.33) deaths per 100,000 individuals in 2015, a reduction in the three latter cancers, from 4.09 (2.92-5.76), 13.04 (10.04-16.95), 1.23 (0.46-3.34), and 1.76 (1.28-2.42) deaths per 100,000 individuals in 1990, respectively. CONCLUSIONS: In conclusion, despite disparities among different provinces, overall mortality rate of urological cancers decreased significantly since 1990s in Iran.

The lipid accumulation product is a novel, safe and inexpensive index of central lipid over accumulation based on waist circumference and fasting concentration of circulating triglycerides. This study was designed to investigate the ability of lipid accumulation product to predict Cardio-metabolic risk factors in postmenopausal women. In this Cross-sectional study, 264 postmenopausal women by using convenience sampling method were selected from menopause clinic in Tehran. Cardio-metabolic risk factors were measured, and lipid accumulation product (waist-58×triglycerides [nmol/L]) was calculated. Optimal cut-off point of lipid accumulation product for predicting metabolic syndrome was estimated by ROC (Receiver-operating characteristic) curve analysis. Metabolic syndrome was diagnosed in 41.2% of subjects. Optimal cut-off point of lipid accumulation product for predicting metabolic syndrome was 47.63 (sensitivity:75%; specificity:77.9%). High lipid accumulation product increases risk of all Cardio-metabolic risk factors except overweight, high Total Cholesterol, high Low Density Lipoprotein Cholesterol and high Fasting Blood Sugar in postmenopausal women. Our findings show that lipid accumulation product is associated with metabolic syndrome and some Cardio-metabolic risk factors Also lipid accumulation product may have been a useful tool for predicting cardiovascular disease and metabolic syndrome risk in postmenopausal women.

BACKGROUND: The substantial increase in life expectancy during recent decades has left all countries with a high number of elderly people that have particular health needs. Health policy-makers must be aware of the most prevalent causes of deaths and DALYs in this age group, as well as geriatric syndromes, in order to provide appropriate care and allocate resources in an equitable manner. METHODS: The Global Burden of Disease study 2010 (GBD 2010), conducted by the institute for Health Metrics and Evaluation team, estimated the worldwide burden of diseases from 1990 to 2010. Its estimations were conducted on the basis of the proportion of deaths, the duration of symptoms and disability weights for sequelae, years lived with disability (YLDs), years of life lost (YLLs), and disability adjusted life years (DALYs) attributable to different diseases. In the present study, we extracted the data regarding the top five most prevalent causes of deaths, DALYs, and geriatric syndromes in the elderly based on the aforementioned GBD 2010, discussed the results using some tables and figures, reviewed the results, described the limitations of GBD 2010, and finally provided some recommendations as potential solutions. RESULTS: According to GBD 2010, the total number of deaths in Iran in 1990 was 321,627, of which 116,100 were in elderly people (those aged 60 years and above), meaning that 36.10% of all deaths occurred in the elderly. Among all diseases in this year, the first to third ranked causes of death were ischemic heart disease (IHD; 29.44%), neoplasms (13.52%), and stroke (7.24%). In comparison, the total number of deaths in Iran increased to 351,814 in 2010, with 213,116 of these occurring in the elderly (60.58% of deaths), but the most prevalent causes of death remained the same as in 1990. The highest 1990 DALYs rates were the result of IHD (21.56%), neoplasms (10.70%), and stroke (4.85%). IHD (22.77%), neoplasms (9.48%), and low back pain (LBP; 5.72%) were the most prevalent causes of DALYs in older Iranian adults in 2010. The fourth and fifth ranked causes of deaths and DALYs in both 1990 and 2010, both in Iran and globally, were different diseases and geriatric syndromes in the elderly Iranian population. CONCLUSION: The aged population of Iran is growing steadily, and there is a need for health policy-makers to create appropriate programs to meet the health needs of elderly people. Although GBD 2010 results are useful in providing burden estimations at regional and national levels, each individual country should estimate its burden of diseases, injuries, and risk factors at a sub-national level to obtain further details regarding the health status of its people. As no comprehensive study regarding elderly people in Iran has previously been conducted, our study will be a major source for identifying the important causes of deaths, DALYs, and geriatric syndromes among this population.
