BACKGROUND: Musculoskeletal disorders (MSDs) are a common problem among carpet weavers. This study was undertaken to introduce affecting personal and occupational factors in developing the number of MSDs among carpet weavers. METHODS: A cross-sectional study was performed among 862 weavers in seven towns with regard to workhouse location in urban or rural regions. Data were collected by using questionnaires that contain personal, workplace, and information tools and the modified Nordic MSDs questionnaire. Statistical analysis was performed by applying Poisson and negative binomial mixed models using a full Bayesian hierarchical approach. The deviance information criterion was used for comparison between models and model selection. RESULTS: The majority of weavers (72%) were female and carpet weaving was the main job of 85.2% of workers. The negative binomial mixed model with lowest deviance information criterion was selected as the best model. The criteria showed the convergence of chains. Based on 95% Bayesian credible interval, the main job and weaving type variables statistically affected the number of MSDs, but variables age, sex, weaving comb, work experience, and carpet weaving looms were not significant. CONCLUSION: According to the results of this study, it can be concluded that occupational factors are associated with the number of MSDs developing among carpet weavers. Thus, using standard tools and decreasing hours of work per day can reduce frequency of MSDs among carpet weavers.

OBJECTIVES: Menopause can have psychological, physical, and vasomotor symptoms along with sexual dysfunction and these symptoms can affect the quality of life (QOL). The purpose of this research was to determine and association the effective factors on QOL among postmenopausal Iranian women. METHODS: This cross-sectional study was conducted in 2015 on 300 postmenopausal women in Hamadan, Iran. We used the Menopause-Specific QOL questionnaire (MENQOL) for measuring QOL in postmenopausal women. SPSS version 16 was used for data analysis. RESULTS: The mean scores of QOL for vasomotor, psychosocial, physical, and sexual domains were 11.65 ± 5.93, 19.36 ± 1.20, 39.12 ± 1.95 and 11.02 ± 5.66, respectively. Higher scores had worse QOL. Using MENQOL scores, our study showed significant differences in QOL based on age, education level, financial status, number of children, employment, and body mass index (BMI). CONCLUSION: Menopause causes a decrease in QOL, which is dependent to age, work, BMI, financial status and number of children variables. Therefore, it is necessary to develop effective intervention programs to improve QOL in postmenopausal women.

OBJECTIVES: This study aimed to investigate the effect of Educational program on quality of life (QOL) in menopausal women in 2016 in Hamadan, Iran. METHODS: In this clinical trial study, 100 postmenopausal women were randomly selected and allocated to case and control group (50 per group). Data collection tool included questionnaires of demographic information and Menopause QOL, which were completed by the samples before the intervention. In the case group, education program was run during 5 sessions for 45 to 60 minutes. Immediately and Three months after intervention, information were collected using questionnaire in both groups and they were analyzed using SPSS 16 software. RESULTS: The menopause women in both intervention and control groups had similar demographics. There was not a significant difference in the QOL mean scores in before of the intervention between the two groups of intervention and control in all dimension of QOL. There was a significantly difference in the mean of QOL scores between the two groups in immediately after the intervention and 3 months after the intervention in dimension of vasomotor, psychosocial, sexual and physical (P < 0.001). CONCLUSIONS: This study recommend that a unit in health and treatment centers be established for training menopausal women about health care by holding didactic classes.

BACKGROUND: Although the role of unintentional injuries as a cause of death in adults is known, there is limited knowledge about such adults’ behaviors. This study aims to investigate the frequency of and factors affecting unintentional injuries among the elderly living in rural areas and their related behaviors. METHODS: A cross-sectional study was carried out in the rural areas of Hamadan County, Iran, in 2016. The sample consists of randomly selected 445 adults aged 60–75 years. Data collection was conducted through face-to-face interviews, using questionnaires. RESULTS: One hundred and forty-three participants (34.7%) experienced 166 injury occurrences. The injuries occurred more in females than in males. There were more mild and severe injuries (48.2% and 31.3%, respectively) than moderate ones (20.5%). The most frequent mechanism of injuries was accidental falls (64.5%). There was a significant relationship between using aid devices and injuries (P=0.001). Among the most applied injury preventive measures as reported by the elderly, crossing streets safely and the use of proper lighting at night had the highest percentages (81.5% and 69.7%, respectively). However, the use of protective handles and plastic flooring in bathrooms in order to prevent slipping had the lowest percentages (less than 1.0%). CONCLUSION: The injuries among the elderly in this study were important health concerns. Injury-related factors should be considered in the development of injury prevention programs.

Infective endocarditis (IE) is an infection of the endothelial surface of the heart and heart valves with serious, even fatal, complications and that often requires long-term and expensive treatment. Dental procedures may lead to IE in high-risk patients. The aim of this study was to evaluate and compare the knowledge of general dentists and dental students concerning the prevention of IE in Hamadan, Iran. In this cross-sectional study, the awareness of general dentists and dentistry students concerning the prevention of IE was evaluated during 2010. A questionnaire was prepared and administered to 58 final-year dental students and 96 general dental practitioners in Hamadan. A total of 154 persons completed the questionnaire. The questionnaire consisted of some demographic questions and questions about awareness of IE in three sections. The gathered data were analyzed by using descriptive statistics, Pearson's chi-square test, Mann-Whitney test, and independent t-tests. The gathered data showed that dentistry students answered the questions about awareness of the prevention of IE more correctly than did general dentists. The overall knowledge of endocarditis prophylaxis among students and dentists was about 65% and 56%, respectively. The students' knowledge was better because 94.9% of the students had desired (acceptable) and relatively desired knowledge; this result for dentists, however, was 82.3%. In our study, the overall awareness level of the study population was moderate. Dentist and students believed that patients with prosthetic valves and previous IE were the most common cardiac disease cases that required prophylaxis. The most common prophylactic regimen was in accordance with the guidelines of the American Heart Association and was a single dose of 2 g amoxicillin 1 hour before treatment. The results indicated that gender had no effect on the level of knowledge; however, there was a statistically significant relationship between age and level of knowledge.

Longitudinal data are prevalent in clinical research; due to their correlated nature, special analysis must be used for this type of data. Creatinine is an important marker in predicting end-stage renal disease, and it is recorded longitudinally. This study compared the prediction performance of linear regression (LR), linear mixed-effects model (LMM), least-squares support vector regression (LS-SVR), and mixed-effects least-squares support vector regression (MLS-SVR) methods to predict serum creatinine as a longitudinal outcome.
