Meta-analysis of Smoking Prevalence in Iran

Background: There are numerous studies and documents regarding the prevalence of smoking in Iran. Thus, to provide suitable information for decision-making and policy-making in this regard, the prevalence of smoking in Iran was evaluated using the meta-analysis of the results of the existing researches. Methods: Data were collected by searching the keywords cigarette, smoking, tobacco, and nicotine in English databases, searching their Persian equivalents in Persian Databases, and in non-electronic resources. After studying the titles and texts of collected articles, the repeated and irrelevant cases were excluded. Cases which had the inclusion criteria of this meta-analysis were entered into the Stata software. According to heterogeneity results, random effect model was used to estimate the prevalence of smoking. Findings: In initial studies and non-communicable surveillance system, 274992 Iranian adults were studied regarding daily smoking. Among initial studies, smoking prevalence varied from 12.3% to 38.5% in men, and from 0.6% to 9.8% in women. Based on the meta-analysis of initial studies and risk factors of non-communicable disease surveillance system, smoking prevalence was estimated 21.7% and 19.8% in men and 3.6% and 0.94% in women, respectively. Moreover, smoking prevalence in all subjects was estimated 13.9% according to the meta-analysis of the initial study. Conclusion: The findings of this meta-analysis revealed that a significant part of the general population over 15 years of age, and one fifth of Iranian male adults smoke. Thus, concerning causal relationship confirmed between smoking and most diseases, if suitable guidelines are not employed the diseases related to this factor will increase in Iran.

Global, regional and national burden of bladder cancer and its attributable risk factors in 204 countries and territories, 1990–2019: a systematic analysis for the Global Burden of Disease study 2019

Introduction The current study determined the level and trends associated with the incidence, death and disability rates for bladder cancer and its attributable risk factors in 204 countries and territories, from 1990 to 2019, by age, sex and sociodemographic index (SDI; a composite measure of sociodemographic factors). Methods Various data sources from different countries, including vital registration and cancer registries were used to generate estimates. Mortality data and incidence data transformed to mortality estimates using the mortality to incidence ratio (MIR) were used in a cause of death ensemble model to estimate mortality. Mortality estimates were divided by the MIR to produce incidence estimates. Prevalence was calculated using incidence and MIR-based survival estimates. Age-specific mortality and standardised life expectancy were used to estimate years of life lost (YLLs). Prevalence was multiplied by disability weights to estimate years lived with disability (YLDs), while disability-adjusted life years (DALYs) are the sum of the YLLs and YLDs. All estimates were presented as counts and age-standardised rates per 100 000 population. Results Globally, there were 524 000 bladder cancer incident cases (95% uncertainty interval 476 000 to 569 000) and 229 000 bladder cancer deaths (211 000 to 243 000) in 2019. Age-standardised death rate decreased by 15.7% (8.6 to 21.0), during the period 1990–2019. Bladder cancer accounted for 4.39 million (4.09 to 4.70) DALYs in 2019, and the age-standardised DALY rate decreased significantly by 18.6% (11.2 to 24.3) during the period 1990–2019. In 2019, Monaco had the highest age-standardised incidence rate (31.9 cases (23.3 to 56.9) per 100 000), while Lebanon had the highest age-standardised death rate (10.4 (8.1 to 13.7)). Cabo Verde had the highest increase in age-standardised incidence (284.2% (214.1 to 362.8)) and death rates (190.3% (139.3 to 251.1)) between 1990 and 2019. In 2019, the global age-standardised incidence and death rates were higher among males than females, across all age groups and peaked in the 95+ age group. Globally, 36.8% (28.5 to 44.0) of bladder cancer DALYs were attributable to smoking, more so in males than females (43.7% (34.0 to 51.8) vs 15.2% (10.9 to 19.4)). In addition, 9.1% (1.9 to 19.6) of the DALYs were attributable to elevated fasting plasma glucose (FPG) (males 9.3% (1.6 to 20.9); females 8.4% (1.6 to 19.1)). Conclusions There was considerable variation in the burden of bladder cancer between countries during the period 1990–2019. Although there was a clear global decrease in the age-standardised death, and DALY rates, some countries experienced an increase in these rates. National policy makers should learn from these differences, and allocate resources for preventative measures, based on their country-specific estimates. In addition, smoking and elevated FPG play an important role in the burden of bladder cancer and need to be addressed with prevention programmes.publishedVersio

Knowledge and Attitude of Students at Alzahra University about Breast Self-Examination, Iran

Background: Breast cancer is the most common preventable cancer among women. One of the ways of prevention and early detection of breast cancer is breast self-examination (BSE). Thus, we decided to conduct a study about the knowledge and attitude toward BSE among the students of Alzahra University, Iran. Methods: This was a cross-sectional analytical study in which 135 female students aging 18-26 years were enrolled using stratified random sampling. Data was collected by valid and reliable questionnaires. Descriptive statistics and chi-square test were used to analyze the data. Results: While most students (45.9%) had an average level of knowledge about BSE, married students were significantly more knowledgeable (P = 0.007). The majority of students (68.1%), especially older, married students and those with a positive family history of breast cancer, had more positive attitude about BSE. The most popular way of gaining information among students was mass media. Students who gained information from university books had significantly more knowledge than others (P < 0.001). Subjects who obtained information from mass media had more positive attitude than others (P = 0.04). In addition, students with more knowledge had significantly more positive attitude (P < 0.001). Conclusion: The knowledge and attitude about BSE is less than satisfactory even among university students. The values would probably be even less among the general female population in Iran. Proper and more intense educational programs about BSE should be scheduled even in higher education institutions. Keywords: Knowledge, Attitude, Breast self examination, Students

Asthma and Allergic Rhinitis Correlation in Palm Tree Workers of Jahrom City in 2016

Introduction: Allergic rhinitis and asthma can be related to occupation. The present study aimed to investigate the correlation between asthma or allergic rhinitis and employment in the palm tree gardens of Jahrom, Iran.   Materials and Methods: This was a cross-sectional study including 50 palm tree garden workers and a control group of 50 office employees. Data collection included demographics, as well as standard International Study of Asthma and Allergies in Childhood (ISAAC) and A New Symptom-Based Questionnaire for Predicting the Presence of Asthma (ASQ) questionnaires. Data were analyzed using SPSS22. Descriptive statistics, chi-square test, t-test, and logistics regression were used to analyze data.   Results: The correlation between asthma and occupation was significant (       P=0.046); and asthma prevalence was higher in palm tree garden workers. However, no relationship was observed between age, duration of employment, smoking cigarettes, hookah, or opium addiction with asthma. Furthermore, in this study, no significant relation was observed between the prevalence of asthma and contact with dust, contact with pets’ skin and hair, family history of asthma, or the use of perfume and air freshener. The symptoms of allergic rhinitis (including sneezing, runny nose, and blocked nose) were significantly greater in palm tree garden workers (P=0.038). These symptoms in both workers and office employees were higher in spring.   Conclusion: In our study, allergic rhinitis and asthma were more common in palm tree garden workers than in the general population. According to our study, people working in this occupation should take necessary precautions

Post-treatment Clinical Outcomes of Cutaneous Leishmaniosis in the Bam Area, South Eastern Iran: Analysis of over 9,000 Cases

Background: Knowledge about risk or protective factors for post-treatment outcomes in Cutaneous Lishmaniosis are rare, especially in endemic areas such as Iran. The present study aimed to evaluate the association between the outcome of infection, clinical manifestation, and treatment with adverse post-treatment outcomes in Cutaneous Lishmaniosis patients. Methods: This was a cross sectional study based on recently collected data of 9077 Cutaneous Lishmaniosis patients (4585 female and 4492 male) from March 2003 to March 2011 in the Bam area, Iran. Multivariable multinomial logistic regression was applied to assess the effect of outcome of infection, clinical manifestation and treatment on relapse, treatment after interruption, treatment failure and clinical resistance. Results: Head lesions were strongest risk factor for relapse (Odds Ratio, OR=4.21; CI 95%: 3.56-4.98), treatment after interruption (2.00; 1.70-2.35), treatment failure (6.61; 5.17-8.45) and clinical resistance (2.62; 2.00-3.44). Family occurrence (yes vs. no), intra lesion therapy method, treatment duration (>3 v. ≤ 3 week) and source of detection by Surveillance (active vs. passive), were the most protective factors for relapse (OR=0.58; CI 95%: 0.46-0.74), treatment after interruption (0.36; 0.31-0.42) treatment failure (0.24; 0.20-0.29) and clinical resistance (0.24; 0.09-0.67). Conclusion: Head lesions and treatment variables (e.g. therapy method and duration) could predict the occurrence of adverse post-term outcomes of Cutaneous Lishmaniosis. Further longitudinal studies have to clarify cause and effect relationships
