Objective (s): The aim of this study was to determine the level of knowledge and attitude toward child abuse among general practitioners working in Kerman. Methods: A semi-structured questionnaire was developed based on child abuse literature. 200 physicians participated in this study. 3 questionnaires were filled incorrectly, thus deleted and 197 questionnaires were analyzed. The validity and reliability of the questionnaire were assessed. Results: Most participants did not have adequate knowledge especially in the sexual and psychological aspects. There was a significant relation between knowledge and gender with attitudes toward child abuse. Conclusion: The findings indicated that physicians do not have adequate knowledge and proper attitude regarding child abuse. Implementation of educational programs on child abuse seems necessary for medical students.

Objective (s): To measure quality of life in hemodialysis patients. Methods: This was a cross-sectional study carried out in two centers in Kerman. Quality of life was measured using the Iranian version of the SF-36. Results: In all 100 patients with end stage renal disease receiving hemodialysis were studied. The mean age of patients was 50.91 (SD=l4.76) years and the mean time of dialysis for patients was 31.76 (SD=37.33) months. The most cause of renal failure was diabetes mellitus and the most comorbidity was heart disease. In all domains of the SF-36, it was found that patients reported lower scores than healthy individuals. The lowest score was found for General Health. Conclusion: These results show that hemodialysis patients suffer from a poor quality of life and this suggests that these patients need more effective management.

Background: The recent devastating earthquake of December 26 in Bam, 2003 created various risk factors; caused a sharp increase in incidence of anthroponotic cutaneous leishmaniasis (ACL) cases and reached to an epidemic proportion. The objective of this study was to evaluate the status of ACL cases five years before the earthquake compared to the cases occurred five years after the earthquake (1999–2008). Methods: Status of disease was assessed retrospectively for the five years before the earthquake and prospectively for the five years after the earthquake. Identification was confirmed by smear and polymerase chain reaction (PCR). Results: The mean annual incidence of ACL for the period from 1999 to 2003 was 1.9 per 1000 comparing to post earthquake period, which was 7.6 per 1000. Most of the infection was in individuals of 20 years (P< 0.0001) in post earthquake era. The anatomical distribution of lesions considerably changed during the two periods. Most of the cases were limited to three zones within the city prior to the earthquake, whereas it was spread throughout different zones after the earthquake. PCR indicated that the CL was due to Leishmania tropica in the city. Conclusion: The results strongly suggest that in natural disasters such as earthquakes various precipitating factors in favor of disease will be created, which in turn provide a suitable condition for propagation of the vector and the transmission of the parasite.

Introduction: Iran, similar to other countries, had faced H1N1 flu outbreak in 2009. In order to assess its transmission dynamic, we estimated its force of infection (β) and basic reproductive number (R 0 ). Methods: Within a middle size primary school in Iran, we actively followed students and detected flu-like syndrome among students and their families in the first three months of academic year; October through December 2009. We estimated the probability of disease transmission within families (β) fitting random effects Poisson regression model. Moreover, R 0 within the school was computed based on the number of detected cases. Results: In 452 students, 204 influenza-like syndromes were detected. The estimated β within families was 0.10; increasing one infectious member within each family was associated with 30% increase in this number. The estimated R 0 for the first month was 1.21 (95% C.I.: 0.99, 1.47); corresponding numbers for the first two and first three months were 1.28 (95% C.I.: 1.05, 1.54) and 1.32 (95% C.I.: 1.11, 1.59), respectively. Conclusion: It seems that the dynamic transmission of H1N1 virus was more or less comparable with that in other seasonal species. Our findings showed that the virus mainly circulated among students within schools. In addition, it seems that the transmission rate within families was relatively high.

Leishmaniasis is a zoonotic infection caused by a protozoa belonging to the genus Leishmania. Its clinical manifestations range from a self-healing cutaneous leishmaniasis to lethal visceral leishmaniasis. We aimed to study the quality of life of patients with cutaneous leishmaniasis in Kerman, Iran. In this cross–sectional study, patients aged more than 16 years with cutaneous leishmaniasis referring to the Department of Dermatology, Kerman Medical School, were enrolled using the simple random sampling method. Data were collected using a demographic data questionnaire including the characteristics of the lesions such as type, size, location, condition, activity of lesions, and previous treatment, the dermatology life quality index (DLQI). A total of 124 patients were enrolled with mean age of 36.9 (±14.9) years (46 men and 78 women). Mean DLQI score was 5.87(±5.96). The highest effect was seen in the symptoms and feelings domains and the lowest effect was seen in the treatment domain of the questionnaire. Quality of life was similar in men and women. Single patients had better mental health compared with married patients. Patients with ulcerated lesions had lower quality of life. Cutaneous leishmaniasis has significant effects on the quality of life of patients. Therefore, its treatment, especially in the ulcerous group, can improve the quality of life in these patients.

- Abstract
Rising drug resistance among pathogenic fungi, paired with a limited antifungal arsenal, poses an increasing threat to human health. To identify antifungal compounds, we screened the RIKEN natural product depository against representative isolates of four major human fungal pathogens. This screen identified NPD6433, a triazenyl indole with broad-spectrum activity against all screening strains, as well as the filamentous mold Aspergillus fumigatus. Mechanistic studies indicated that NPD6433 targets the enoyl reductase domain of fatty acid synthase 1 (Fas1), covalently inhibiting its flavin mononucleotide-dependent NADPH-oxidation activity and arresting essential fatty acid biosynthesis. Robust Fas1 inhibition kills Candida albicans, while sublethal inhibition impairs diverse virulence traits. At well-tolerated exposures, NPD6433 extended the lifespan of nematodes infected with azole-resistant C. albicans. Overall, identification of NPD6433 provides a tool with which to explore lipid homeostasis as a therapeutic target in pathogenic fungi and reveals a mechanism by which Fas1 function can be inhibited., Competing Interests: Declaration of interests L.E.C. and L.W. are co-founders and shareholders in Bright Angel Therapeutics, a platform company for development of novel antifungal therapeutics. L.E.C. is a Science Advisor for Kapoose Creek, a company that harnesses the therapeutic potential of fungi.

- Abstract
Background: Geographic information system (GIS) plays an important role in identifying areas with a high incidence of cancer. In the present study, based on a systematic review of studies by Iranian researchers, we performed a scientometric analysis of the published articles on the spatial epidemiology of cancer. In addition, the geographical distribution of certain types of cancer in Iran is presented., Methods: A literature search was conducted using electronic databases such as PubMed and NLM Gateway, Institute for Scientific Information, Scopus, Google Scholar, and Cochrane Library for relevant articles published from 2000 to 2021. The search was performed using a combination of medical subject heading terms and keywords. A narrative synthesis was performed, and descriptive data were expressed as frequency and percentage., Results: Of the 200 identified articles, 31 studies published in 15 different journals were included in this systematic review. Results showed a wide variation in high-risk breast cancer clusters. However, a similar incidence of gastrointestinal cancers has been reported, and high-risk clusters were identified in the north and the northwest of Iran. Skin cancer and acute lymphoblastic leukemia were more prevalent in the central provinces., Conclusion: The current volume of studies on the spatial epidemiology of cancer in Iran, with a CiteScore quartile of Q1, is inadequate to guide health policymakers. The geographical distribution of many prevalent types of cancer has not been assessed by Iranian researchers. Furthermore, the classification of high- and low-risk geographical clusters of cancers was not completely homogeneous., Competing Interests: None declared., (Copyright: © Iranian Journal of Medical Sciences.)

- Abstract
Breast cancer is the most common cause of premature mortality among women, and screening is one of the most important means of early diagnosis of breast cancer. This qualitative study was conducted to explore strategies for promoting breast cancer screening behaviors from the perspective of health volunteers in south-east Iran. Data collection was performed through focus groups. Using the purposive sampling method, 35 participants were selected and data were analyzed using a specific qualitative content analysis framework. By analyzing the data to provide strategies for promoting breast cancer screening behaviors, the main theme of "organizational transformation" with five subthemes including the promotion of health-centered beliefs in society, the development of culture-based training, the media revolution, financial support, and the provision of efficient health-care providers were extracted. According to the results of the study, the development of organizational transformation plays an important role in planning for the promotion of breast cancer screening.

- Abstract
A common strategy for identifying molecules likely to possess a desired biological activity is to search large databases of compounds for high structural similarity to a query molecule that demonstrates this activity, under the assumption that structural similarity is predictive of similar biological activity. However, efforts to systematically benchmark the diverse array of available molecular fingerprints and similarity coefficients have been limited by a lack of large-scale datasets that reflect biological similarities of compounds. To elucidate the relative performance of these alternatives, we systematically benchmarked 11 different molecular fingerprint encodings, each combined with 13 different similarity coefficients, using a large set of chemical-genetic interaction data from the yeast Saccharomyces cerevisiae as a systematic proxy for biological activity. We found that the performance of different molecular fingerprints and similarity coefficients varied substantially and that the all-shortest path fingerprints paired with the Braun-Blanquet similarity coefficient provided superior performance that was robust across several compound collections. We further proposed a machine learning pipeline based on support vector machines that offered a fivefold improvement relative to the best unsupervised approach. Our results generally suggest that using high-dimensional chemical-genetic data as a basis for refining molecular fingerprints can be a powerful approach for improving prediction of biological functions from chemical structures.

- Abstract
Background: Opioid abuse is among the most ubiquitous issues world-wide, and when it happens in mothers, it puts them at risk of diseases that can be transferred to the next generation. Previous studies have indicated that morphine addiction during pregnancy could inhibit development in rat embryos and infants. The present study focused on the effects of maternal consumption of morphine on rat skeletal system development and also investigate the molecular pathway of chondrogenesis and osteogenesis of infants from control and addicted rat groups., Methods: Thirty-two female rats were randomly assigned to four groups. The groups consisted of one- and seven-day-old female infants which were born of morphine-dependent mothers and a control group for each of them. Experimental groups received oral morphine at the final dose of 0.4 mg/ml/day. Withdrawal signs were confirmation of morphine dependency. Female rats were crossed with male rats and coupling time was recorded. Fixed bones of all groups were processed and then stained by hematoxyline-eosin method. Thickness and cell number of proximal and distal growth plate of bones were measured. The cartilage and bone cells were stained by alcian blue/alizarin red method. Additionally, the gene expression of alkaline phosphatase, osteocalcin, and COLL2 and SOX9 gene expression were studied immuno-histochemically., Results: Unfavorable effects of morphine on histological measurements were observed in one-day and seven-day infants, with more effects on seven-day infants. The thickness and cell number of the proximal and distal growth plate of morphine-dependent rat offsprings were reduced significantly. Furthermore, morphine reduced growth of primary and secondary ossification centers, and thus, longitudinal bone growth was reduced. Moreover, a decrease in the alkaline phosphatase, osteocalcin, COLL2 and SOX9 gene expression, and the number of stained cells was observed. More adverse effects of morphine in seven-day infants compared to one-day infants which showed the time dependent of morphine to the time length of administration., Conclusion: Histochemistry and immunohistochemistry findings on cartilage and bone matrix formation, as well as protein expression of chondrogenic and osteogenic markers suggest that morphine dependence in pregnant mothers may impair intra-cartilaginous osteogenesis in post-natal rats.

- Abstract
The quality of life (QoL) questionnaire (SF-36) contains 36 questions in eight subscales. It requires much time to fill in by the respondent. The objective of this study was to use Rasch models to develop a questionnaire that brings the desired outcome of the QoL of people. Therefore, a new questionnaire was provided that is more motivating and time-saving for respondents than SF-36. The QoL of life assessment data of 325 β-thalassemia major (β-TM) and β-thalassemia intermedia (β-TI) patients in Kerman, Iran, was used as research data. In this study, the appropriate questions were classified in a limited dimensional framework using the exploratory factor analysis (EFA). The correctness of the factor structure was assessed by confirmatory factor analysis (CFA). The quality of the questions was evaluated by Rasch modeling [partial credit model (PCM)] and item analysis to ensure the validity and reliability of the questionnaire. Finally, the Pearson correlation coefficient was used to compare the new questionnaire with the previous one. This process resulted in the development of a new questionnaire with five subscales and 20 questions. The construct validity of the new questionnaire was good. The reliability index of the questionnaire was 0.75, and the Pearson correlation coefficient between the QoL scores gained from the previous and the new questionnaires was 0.93 that indicates the strength of the correlation. The use of Rasch analysis in this study resulted in the development of a new reliable and valid questionnaire.

- Abstract
Chemical-genetic interactions-observed when the treatment of mutant cells with chemical compounds reveals unexpected phenotypes-contain rich functional information linking compounds to their cellular modes of action. To systematically identify these interactions, an array of mutants is challenged with a compound and monitored for fitness defects, generating a chemical-genetic interaction profile that provides a quantitative, unbiased description of the cellular function(s) perturbed by the compound. Genetic interactions, obtained from genome-wide double-mutant screens, provide a key for interpreting the functional information contained in chemical-genetic interaction profiles. Despite the utility of this approach, integrative analyses of genetic and chemical-genetic interaction networks have not been systematically evaluated. We developed a method, called CG-TARGET (Chemical Genetic Translation via A Reference Genetic nETwork), that integrates large-scale chemical-genetic interaction screening data with a genetic interaction network to predict the biological processes perturbed by compounds. In a recent publication, we applied CG-TARGET to a screen of nearly 14,000 chemical compounds in Saccharomyces cerevisiae, integrating this dataset with the global S. cerevisiae genetic interaction network to prioritize over 1500 compounds with high-confidence biological process predictions for further study. We present here a formal description and rigorous benchmarking of the CG-TARGET method, showing that, compared to alternative enrichment-based approaches, it achieves similar or better accuracy while substantially improving the ability to control the false discovery rate of biological process predictions. Additional investigation of the compatibility of chemical-genetic and genetic interaction profiles revealed that one-third of observed chemical-genetic interactions contributed to the highest-confidence biological process predictions and that negative chemical-genetic interactions overwhelmingly formed the basis of these predictions. We also present experimental validations of CG-TARGET-predicted tubulin polymerization and cell cycle progression inhibitors. Our approach successfully demonstrates the use of genetic interaction networks in the high-throughput functional annotation of compounds to biological processes., Competing Interests: I have read the journal's policy and the authors of this manuscript have the following potential competing interests: Authors Simpkins, Nelson, and Myers have licensed the CG-TARGET software for commercial use (z.umn.edu/cgtarget).

- Abstract
Background: Breast cancer is common among cancer diseases and the second leading cause of death among women worldwide. The breast cancer-caused death is directly associated with diagnosis time of the disease. Screening is one of the major methods for health promotion in human societies. However, many women still refuse to do the periodic screening. The present study is aimed to analyze the experiences of health volunteers in order to understand the barriers to breast cancer screening among women at southeast of Iran. Methods: Data collection was performed through focus groups. Using the purposive sampling method, 24 participants were selected and then were allocated to 6-member groups. The data were analysed using Lundman and Graneheim qualitative content analysis. Results: The main theme of “Health Damage Context” was extracted with four main categories, including: family barriers, cultural and social barriers, personal barriers and organizational barriers. Conclusion: Based on the results of the present study, there are numerous barriers to regular breast cancer screening, and for the same reasons, the willingness to screening is sometimes not satisfactory. Therefore, in case of the women’s referral to health centers, nurses and other health-care professionals should inform them about the role of different screening methods in early diagnosis and rapid treatment of breast cancer., (Creative Commons Attribution License)

- Abstract
Summary: Chemical-genomic approaches that map interactions between small molecules and genetic perturbations offer a promising strategy for functional annotation of uncharacterized bioactive compounds. We recently developed a new high-throughput platform for mapping chemical-genetic (CG) interactions in yeast that can be scaled to screen large compound collections, and we applied this system to generate CG interaction profiles for more than 13 000 compounds. When integrated with the existing global yeast genetic interaction network, CG interaction profiles can enable mode-of-action prediction for previously uncharacterized compounds as well as discover unexpected secondary effects for known drugs. To facilitate future analysis of these valuable data, we developed a public database and web interface named MOSAIC. The website provides a convenient interface for querying compounds, bioprocesses (Gene Ontology terms) and genes for CG information including direct CG interactions, bioprocesses and gene-level target predictions. MOSAIC also provides access to chemical structure information of screened molecules, chemical-genomic profiles and the ability to search for compounds sharing structural and functional similarity. This resource will be of interest to chemical biologists for discovering new small molecule probes with specific modes-of-action as well as computational biologists interested in analysing CG interaction networks., Availability and Implementation: MOSAIC is available at http://mosaic.cs.umn.edu., Contact: hisyo@riken.jp, yoshidam@riken.jp, charlie.boone@utoronto.ca or chadm@umn.edu., Supplementary Information: Supplementary data are available at Bioinformatics online.

Mutations can alter the response of cells in the presence of a compound, revealing chemical-genetic interactions that can elucidate a compound's mode of action. We developed a highly parallel, unbiased yeast chemical-genetic screening system involving three key components. First, in a drug-sensitive genetic background, we constructed an optimized diagnostic mutant collection that is predictive for all major yeast biological processes. Second, we implemented a multiplexed (768-plex) barcode-sequencing protocol, enabling the assembly of thousands of chemical-genetic profiles. Finally, based on comparison of the chemical-genetic profiles with a compendium of genome-wide genetic interaction profiles, we predicted compound functionality. Applying this high-throughput approach, we screened seven different compound libraries and annotated their functional diversity. We further validated biological process predictions, prioritized a diverse set of compounds, and identified compounds that appear to have dual modes of action.

- Abstract
Background: The purpose of this study was to determine the prevalence and related factors of low birth weight (LBW) in the Southeast of Iran., Methods: This cross-sectional study was carried out in Kerman province. Data were collected from Iranian Maternal and Neonatal Network at public and private hospitals. All live births from March 2014 to March 2015 considered as the source population. The risk factors including maternal age, gravida, parity, abortion, pregnancy risk factors, maternal nationality, maternal education, maternity insurance, place of living, consanguinity, neonate sex, preterm labor, place of birth, delivery manager, and delivery type were compared between LBW and normal birth weight groups., Results: The prevalence of LBW was 9.4% in the present study. Preterm labor (odds ratio [OR]: 22.06; P < 0.001), neonate female sex (OR: 1.41; P < 0.001), low parity (OR: 0.85; P < 0.001), pregnancy age <18 years (OR: 1.26; P = 0.012), pregnancy age >35 years (OR: 1.21; P = 0.001), delivery by cesarean section (OR: 1.17; P = 0.002), pregnancy risk factors (OR: 1.67; P < 0.001), maternal illiteracy (OR: 1.91; P < 0.001), living in the rural area (OR: 1.19; P < 0.001), consanguineous (OR: 1.08; P = 0.025), and delivery by obstetrician (OR: 1.12; P = 0.029) were identified as significant factors associated with LBW in this study., Conclusions: Prevention of preterm labor, consanguineous marriage, pregnancy age <18 and >35 years old, and maternal medical risk factors are some critical interventions to reduce its burden. Increasing the access to high-quality health-care services in rural and deprived areas is another effective strategy for the prevention of LBW., Competing Interests: There are no conflicts of interest.

- Abstract
Background and Aim: Migraine is a common form of headache that affects patients quality of life negatively. In addition to pharmacologic treatment, there are a variety of nonpharmacologic treatments for migraine headache. In present study, we examined the effect of prayer on intensity of migraine pain., Methods: In a prospective, randomized, controlled trial from October 2013 to June 2014, this study has been conducted in Kerman, Iran. We randomly assigned 92 patients in 2 groups to receive either 40 mg of propranolol twice a day for 2 month (group "A") or 40 mg of propranolol twice a day for 2 months with prayer (group "B"). At the beginning of study and 3 months after intervention, patients' pain was measured using the visual analogue scale., Results: At the beginning of study and before intervention, the mean score of pain in patients in groups A and B were 5.7 ± 1.6 and 6.5 ± 1.9, respectively. According to results of independent t test, mean score of pain intensity at the beginning of study were similar between patients in 2 groups (P > .05). Three month after intervention, mean score of pain intensity decreased in patients in both groups. At this time, the mean scores of pain intensity were 5.4 ± 1.1 and 4.2 ± 2.3 in patients in groups A and B, respectively. This difference between groups was statistically significant (P < .001)., Conclusions: The present study revealed that prayer can be used as a nonpharmacologic pain coping strategy in addition to pharmacologic intervention for this group of patients., (© The Author(s) 2016.)

- Abstract
Background: To evaluate the effectiveness of a capacity-building intervention administered through a primary health care (PHC) system on community disaster preparedness in Iran., Methods: A controlled community intervention trial with pre- and postassessments was conducted in 2011 in 3 provinces of Iran. In each province, 2 areas were chosen and randomly selected as an intervention or control group. A total of 9200 households were in the intervention area and 10 010 were in the control area. In each study group in each province 250 households were sampled for pre- and postassessment surveys. Community health volunteers led by PHC staff administered an educational intervention covering elements of hazard awareness and preparedness, with a focus on earthquakes and floods. Relative changes for awareness and readiness scores were assessed to demonstrate changes in outcome variables from pre- to postassessments in intervention and control groups. An effectiveness test of significance was based on interaction between time and area., Results: Households in intervention communities exhibited improved disaster awareness and readiness with respect to all outcome measures. Relative changes in awareness in intervention and control areas were 2.94 and -0.08, respectively (P < .001). Relative changes for readiness scores were 5.52 in intervention areas and 0.56 in control areas (P < .001). Relative changes for awareness and readiness were significantly correlated with a community's baseline risk perception and previous experience with natural disasters (P < .001)., Conclusions: An educational intervention administered through the PHC system effectively improved disaster awareness and readiness at a community level. For sustainability, community disaster reduction programs must be integrated into routine public health service delivery.

- Abstract
Background: Leishmaniasis is a zoonotic infection caused by a protozoa belonging to the genus Leishmania. Its clinical manifestations range from a self-healing cutaneous leishmaniasis (CL) to lethal visceral leishmaniasis. We aim to examine the quality of life of patients with CL in Kerman, Iran. , Methods: In this cross-sectional study we evaluated 124 patients with CL. The Dermatology Life Quality Index (DLQI) questionnaire was used for measuring quality of life. Data on demographics and characteristics of the lesions also were collected. Mann-Whitney U-test and Kruskal-Wallis were used for data analyses., Results: The mean DLQI score was 5.87 ± 5.96. We observed the highest effect in the symptoms and feelings domains; the lowest effect was seen in the treatment domain of the DLQI. There was no significant difference in DLQI scores between men and women. Patients with ulcerated lesions had lower quality of life (P < 0.05). , Conclusion: CL significantly affects the quality of life of patients. Further studies are suggested to examine the effect of its treatment on the quality of life in these patients.

- Abstract
Introduction: Allergic rhinitis (AR) is a common airway disease. In order to study the prevalence of AR in high school students in Kerman, the Score for Allergic Rhinitis (SFAR) was used and the quality of life in the students affected by rhinitis was evaluated using the SF-36 questionnaire., Materials and Methods: This was a cross-sectional, analytical, descriptive study, based on the SFAR scale. Quality of life in students with AR was evaluated using the SF-36 questionnaire., Results: From 1511 students who completed the SFAR questionnaire, 291 (52.6%, girls; 47.4%, boys) had AR. Domestic dust was the most common cause of the disease. The most common symptoms of AR were rhinorrhea (76.6%), epiphora (76.3%), nasal congestion (64.3%), and itching (54.3%). According to the ARYA scale, (Allergic Rhinitis and its Impact on Asthma), 41.9% of students had moderate-to-severe rhinitis and 58.1% had mild rhinitis. A total of 43.1% of patients with moderate-to-severe rhinitis had a persistent condition and 56.9% had an intermediate condition. Results of the SF-36 questionnaire among students with AR showed a significant difference in physical functioning and bodily pain in comparison with healthy students., Conclusion: The results of this study show that the prevalence of AR among Kerman high school students is 19.3%. Because of the effect of this disease on the life quality of high school students in terms of both physical functioning and bodily pain, efforts should be made to reduce allergen levels as far as possible.

- Abstract
Background: This study seeks to determine the relationships between manifestation of myofibroblasts in the stroma tissue of hyperplastic pre-invasive breast lesions to invasive cancer by investigating clinicopathological data of patients, their effect on steroid receptor expression and HER2, and angiogenesis according to CD34 antigen expression., Methods: 100 cases of invasive ductal carcinoma were immunohistochemically investigated for the presence of smooth muscle actin (SMA), ER/PR, HER2, anti-CD34 antibody and microvessel count (MVC). Patients were scored in four different zones of invasive areas: invasive cancer, DCIS, fibrocystic disease ± ductal intraepithelial neoplasia (FCD ± DIN), and normal tissue. , Results: There was a significant difference in stromal myofibroblasts between all areas except for the stroma of DCIS and FCD ± DIN (P < 0.001). We observed positive significant correlations between stromal myofibroblasts, HER2 expression, and the numbers of involved lymph nodes in invasive cancer, DCIS, and FCD ± DIN (P < 0.001). More myofibroblasts were present in grade III cases, with the least frequent observed among grade I cases in the stroma of those with invasive disease, DCIS, and FCD ± DIN (P < 0.001). MVC was inversely related to stromal myofibroblasts in invasive cancer (P < 0.001) and DCIS (P < 0.001), whereas there was a positive correlation in the stroma of FCD ± DIN (P = 0.002) and normal areas (P = 0.054). There was a significant difference in MVC observed in all areas except for DCIS and FCD ± DIN (P < 0.001). We noted significant inverse correlations between MVC, HER2 expression, and the numbers of involved lymph nodes in invasive cancer and DCIS (P < 0.001). Most MVC were present in grade I, with the least frequent observed in grade III cases in the stroma of invasive cancer, DCIS and FCD ± DIN (P < 0.001). , Conclusion: Angiogenesis can be observed before any significant myofibroblastic changes in the pre-invasive breast lesions. The elevated content of myofibroblasts in stroma of tumor; probably may be a worse prognostic factor and the steps from atypical epithelial hyperplasia to DCIS and then to the invasive carcinoma do not appear to be always part of a linear progression.

- Abstract
Introduction: Iran, similar to other countries, had faced H1N1 flu outbreak in 2009. In order to assess its transmission dynamic, we estimated its force of infection (β) and basic reproductive number (R(0))., Methods: Within a middle size primary school in Iran, we actively followed students and detected flu-like syndrome among students and their families in the first three months of academic year; October through December 2009. We estimated the probability of disease transmission within families (β) fitting random effects Poisson regression model. Moreover, R(0) within the school was computed based on the number of detected cases., Results: In 452 students, 204 influenza-like syndromes were detected. The estimated β within families was 0.10; increasing one infectious member within each family was associated with 30% increase in this number. The estimated R(0) for the first month was 1.21 (95% C.I.: 0.99, 1.47); corresponding numbers for the first two and first three months were 1.28 (95% C.I.: 1.05, 1.54) and 1.32 (95% C.I.: 1.11, 1.59), respectively., Conclusion: It seems that the dynamic transmission of H1N1 virus was more or less comparable with that in other seasonal species. Our findings showed that the virus mainly circulated among students within schools. In addition, it seems that the transmission rate within families was relatively high.

- Abstract
Thalassemia is the most common hemoglobin disorder in the world and thalassemia major and intermedia stand among the most severe forms. Due to recent improvements in treatment, patients with thalassemia have longer life expectancies; hence it is of utmost importance to pay careful attention to their quality of life together with life expectancy. This study was conducted to assess the quality of life in patients with thalassemia and also to compare it between thalassemia major and intermedia. In this cross-sectional study, patients who referred for blood transfusion or follow-up visits were evaluated for their quality of life (QOL). Short Form-36 questionnaire was applied to evaluate QOL. In this study, 308 patients with a mean age of 22.95±4.82 years were evaluated. The scores of QOL were regarded as moderate in eight domains under evaluation; the least score was given to General Health (53.05±16.96) whereas the highest score was given to Physical Functioning (67.95±22.68). The QOL in the patients with thalassemia major was better than those with thalassemia intermedia regarding Physical Functioning and Role Limitation Emotional domains. Compared to injecting chelators, patients who received oral chelators showed to have a better QOL considering Social Functioning and Mental Health domain. The patients under study didn't have a satisfying QOL ; the QOL of patients with thalassemia major was better than that of patients with thalassemia intermedia in only 2 domains of sf-36(Physical Functioning & Role limitation-Emotional). It is then essential that experts pay proper attention to improve QOL among patients.

- Abstract
Background: Addiction is one of the complicated problems in Iranian young population. The social and cultural dimensions of this social disease are less considered. So considering socio-cultural and environmental resources, this study investigated the substructures of addiction according to the viewpoints of high-school students of Kerman, Iran in 2007-2008., Methods: This qualitative study accomplished in ten high schools through a one-day problem finding workshop and continued until data saturation. The resulted terms and phrases were analyzed by content analysis. To assure about the validity and reliability, the outputs reviewed by workshops participants, and classification and codification of the data were executed separately by two experts., Findings: A total of 212 students, 45.3% girls and 54.7% boys, participated in the study. The students introduced the followings as the addiction substantial fundaments: lack of knowledge, positive attitude and interpretation of addiction as a value, family or friends' habit, economy status, psycho-personality problems and availability. Rules infirmity or non-implementation of the current rules enforcement, geographical status and addiction as a conspiracy were also observed in students' statements., Conclusion: The positive attitudes and historical roots of addiction along with the process of changing the values caused the growth of drug addiction in young population which could neutralize the security measures, legislations policy and even the knowledge. Therefore, intensification of personal protective factors and culturalization addressed for improving inner layers of values are recommended.
