The prevalence of cardiovascular risk factors among Tehran urban population is high; particularly of high total cholesterol, low HDL cholesterol levels, and high waist to hip ratio. An effective strategy for life style modification is a cornerstone of a population approach to the cardiovascular risk factors. Moreover, these results will serve as a baseline for assessment of future trends in the risk factors studied.

Data from 6246 participants aged 20-64 years (2339 males and 3907 females) in the cross-sectional phase of Tehran Lipid and Glucose Study (February 1999-May 2000) were used to determine distribution of serum lipid levels after 12-14 hour overnight fast. Mean total cholesterol (TC) concentration was 210 mg/dl. TC was significantly greater in females than males, 213 and 206 mg/dl, respectively (p < 0.0001). Thirty-one percent of population had TC values between 200 and 239 and 24% had values of 240 mg/dl or greater. Mean low-density lipoprotein cholesterol (LDL-C) was 129 and 135 mg/dl in males and females, respectively (p < 0.0001). Twenty-seven percent had LDL-C values between 130 and 159 and 23% had values 160 mg/dl or greater. The mean triglycerides (TGs) values were 190 and 162 mg/dl for males and females, respectively (p < 0.0001). The mean high-density lipoprotein cholesterol (HDL-C) was 39 in males and 45 mg/dl in females (p < 0.0001). The results showed higher levels of TC, LDL-C and TGs and slightly lower HDL-C in Tehranian adults than other studies in the industrialized countries.

We have analyzed the possible relevance of HPV infection for breast cancer risk among Iranian women from north part of Iran. Among women with breast cancer, 25.9% had positive test results for HPV DNA in breast tumor samples in contrast to 2.4% of women with noncancer status (P=0.002). The infection of HPV has increased the risk of breast cancer (OR 14.247; 95% CI 1.558–130.284,P=0.019). The high-risk HPV genotypes (types 16 and 18) in samples of breast cancer patients were the predominant types (53.34%). Other genotypes detected in breast cancer were HPV-6, HPV-11, HPV-15, HPV-23, and HPV-124, and one isolate could not be genotyped compared to HPV reference sequences. While the sole detected HPV in control specimens was HPV-124. Our study reveals that HPV infection and age are the risk factors in breast cancer development in the north part of Iran.

BackgroundTuberculosis (TB) and tobacco use are two major alarming global health issues that tend to be co-prevalent in many developing countries and various surveys have provided evidence on their entangled associations. Accordingly, it is strongly suggested that smoking cessation be incorporated in TB control programs. Therefore, we aimed to evaluate the effectiveness of two smoking cessation methods among newly-diagnosed pulmonary TB patients.MethodsA total of 210 newly-diagnosed pulmonary TB patients from Tehran, Iran with smoking habits were included in this randomized clinical trial during 2012–2013. Patients were assigned to three groups of control (just TB medical treatment), brief advice (TB medical treatment plus individualized counseling sessions of quitting behavioral therapy) and combined intervention (TB medical treatment plus individualized counseling sessions of quitting behavioral therapy plus medical treatment with slow release bupropion). Patients’ abstinence was followed at six time point during six months. Data were analyzed by SPSS v.22 using Generalized Estimating Equations (GEE) model.ResultsAbstinance rate at the end of six months were 71.7 % for combined intervention group, 33.9 % for brief advice group and 9.8 % for the control group (p < 0.001). Combined intervention group and brief advice group respectively had 35 times (p < 0.001, OR = 35.26, 95 % CI = 13.77–90.32) and 7 times (p < 0.001, OR = 7.14, 95 % CI = 2.72–18.72) more odds of not being an active smoker at each time point, compared to the control group.ConclusionConsidering the prevalence and importance of TB and the substantial influence of these preventive measures on controlling tobacco use, application of such programs is recommended.Trial registrationThe survey was registered in the Iranian registry of clinical trials website (irct.ir) in August 31, 2013 with IRCT ID: IRCT2013062613783N1.

This study is designed to evaluate the prevalence of waterpipe tobacco smoking and its related factors among Iranian adults. This is a cross-sectional study carried out during 2013/14 in Tehran, Islamic Republic of Iran, among 1830 citizens aged over 15 years. Sampling was through Stratified multistage cluster sampling with proportional allocation within strata. Global Adult Tobacco Survey (GATS) questionnaire for waterpipe consumption was used for data gathering. Data were statistically analyzed by SPSS software. The prevalence of current waterpipe tobacco smoking was 17.6% .Waterpipe use prevalence in men was significantly more than women (24.2% vs. 11.3%). Multivariate analysis showed that age, sex, cigarette consumption, waterpipe consumption at home and ignorance of safety issues significantly influenced current waterpipe smoking (P = 0.001). Thus, prevalence of waterpipe smoking in Iranian adults is high and significant. Tackling waterpipe smoking should be considered in tobacco control programmes. However, further studies in this field are needed. La technique utilisée était celle de l'échantillonnage en grappe stratifié à plusieurs niveaux avec allocation proportionnelle dans les strates. Le questionnaire de l'enquête mondiale sur le tabagisme chez les adultes pour la consommation de tabac par pipe à eau a été utilisé afin de collecter les données. Celles-ci ont été analysées sur le plan statistique à l'aide du logiciel SPSS. La prévalence de la consommation de tabac par pipe à eau au moment de l'étude était de 17,6 %, et était plus importante chez les hommes que chez les femmes (24,2 % contre 11,3 %). L'analyse multivariée a montré que l'âge, le sexe, la consommation de cigarettes, la consommation de pipe à eau à la maison et l'ignorance des questions de sécurité influençaient de façon significative la consommation de tabac par pipe à eau (p = 0,001). Par conséquent, la prévalence de la consommation de tabac par pipe à eau est élevée et significative parmi les adultes iraniens. La question de la consommation de tabac par pipe à eau devrait être traitée dans le cadre des programmes de lutte antitabac. Néanmoins, d'autres études dans ce domaine sont requises. ‫اإلسالمية‬ ‫إيران‬ ‫مجهورية‬ ‫املتوسط‬ ‫لرشق‬ ‫الصحية‬ ‫املجلة‬ ‫العرشون‬ ‫و‬ ‫الثالث‬ ‫املجلد‬ ‫الثاين‬ ‫العدد‬ 95

Rhabdomyolysis is a clinical and biochemical syndrome occurring when skeletal muscle cells erupt and result in release of creatine phosphokinase (CPK), lactate dehydrogenase (LDH) and myoglobin into the interstitial space and plasma. Mechanical trauma, compression, excessive muscle activity and ischemia are frequent causes, but non-traumatic rhabdomyolysis is usually caused by a toxic reaction to drugs. In this study, 181 patients suspected of rhabdomyolysis were admitted to the poisoning center of Loghman-Hakim Hospital in Tehran during one year (September 2004 to September 2005) were studied. Patients were included on the basis of physical examination and blood analysis for CPK and LDH. Rhabdomyolysis was confirmed if CPK level has been greater than 975 U/L. Out of 181 patients, 64 were female and 117 were male with an age range between 13—78 years. One-hundred and forty-three (79%) patients had CPK greater than 975 U/L. In 6% of the cases, multiple drug poisoning were observed. Two patients (1.1%) had muscle pain, five patients (2.8%) had rigidity and five patients (2.8%) had muscle inflammation. One-hundred and nineteen patients (65.7%) were febrile. The most common cause of rhabdomyolysis was opium. Blood ALT showed an increase in 109 patients (60.9%), AST in 80 patients (44.7%), and LDH in 144 patients (79.6%). Fifty patients (28.2%) had higher blood direct bilirubin and 64 patients (36.4%) showed higher total bilirubin. Six percent of patients had been diagnosed as ARF by indication of creatinine greater than 1.4 mg/dL. Five percent of patients had hypernatremia and 1.1% of patients had hyperkalemia. It is concluded that rhabdomyolysis is a matter of concern in human poisonings and needs special approach to attend. Human & Experimental Toxicology (2007) 26: 557—561.

Background High-resolution computed tomography (HRCT) is the gold standard for the evaluation of cystic fibrosis (CF) lung disease; however, lung ultrasound (LUS) is being increasingly used for the assessment of lung in these patients due to its lower cost, availability, and lack of irradiation. We aimed to determine the diagnostic performance of LUS for the evaluation of CF pulmonary exacerbation. Methods This cross-sectional study included patients with CF pulmonary exacerbation admitted to Masih Daneshvari Hospital, Tehran, Iran, from March 21, 2020 to March 20, 2021. Age, gender, and body mass index (BMI) of the patients were recorded. All patients underwent chest X-ray (CXR), HRCT, and LUS on admission. Pleural thickening, atelectasis, air bronchogram, B-line, and consolidation were noted in LUS and then compared with the corresponding findings in CXR and HRCT. Taking HRCT findings as reference, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and diagnostic accuracy (DA) of LUS and CXR for the detection of each pulmonary abnormality were determined. Results Of the 30 patients included in this study, with a mean age of 19.62 ± 5.53 years, 14 (46.7%) were male. Of the 15 patients aged 2–20 years, BMI was below the 5th percentile in 10 (66.7%), within the 5–10 percentiles in 1 (6.7%), 10–25 percentiles in 3 (20%), and 25-50 percentiles in 1 (6.7%). The mean BMI for 15 patients > 20 years was 18.03 ± 2.53 kg/m2. LUS had better diagnostic performance compared to CXR for the detection of air bronchogram, consolidation, and pleural thickening (area under the receiver operating characteristic curve [AUROC]: 0.966 vs. 0.483, 0.900 vs. 0.575, and 0.656 vs. 0.531, respectively). Also, LUS was 100% and 96.7% specific for the diagnosis of pleural effusion and atelectasis, respectively. Conclusions LUS appears to be superior to CXR and comparable with HRCT for the evaluation of CF pulmonary exacerbation, especially in terms of air bronchogram and consolidation detection. LUS can be used to lengthen the HRCT evaluation intervals in this regard or utilized along with HRCT for better evaluation of CF pulmonary exacerbation.
