Objective Work-related musculoskeletal disorders are one of dentists’ most common occupational health problems. Human error is considered one of the critical factors of medical error. Musculoskeletal abnormality due to inappropriate work postures and mental workload are two important causes of human error in dental operations. Hence, this study investigates dentists’ mental workload and the incidence of skeletal-muscular disorders. Materials & Methods A cross-sectional descriptive study was conducted in Shahid Shukri Dental Hospital in 2021. The sampling was done via the targeted sampling method and 42 individuals were included in the study. The NASA task load index and the Nordic questionnaire were used to collect the data. Data analysis was done using the SPSS software, version 26, at the significance level of 0.05. Results The average percentage of disorders were as follows: Neck area=30.1%, left shoulder=11.76%, right shoulder=13.74%, right elbow=9.23%, left elbow=6.56%, right wrist=28%, left-hand wrist=25.06%, upper back area=20.1%, waist=13.8%, hip and thigh=17.1%, knee=26% and ankle=23.46%. Age and work experience had a significant relationship with the prevalence of musculoskeletal disorders (P<0.05). The effort component with a Mean±SD of 74.95±22.16 received the highest score and discouragement with a Mean±SD of 49.92±26 got the lowest score compared to other components. The central sterilization department, with a mean of 67.41±24.86, exhibited a higher mental workload than other departments. In contrast, the admission department, with a mean of 50.72±26.59, reported a lower mental workload than other cases. Conclusion Musculoskeletal disorders are related to workload and work capacity. Creating suitable working conditions, providing more training programs to employees, and strengthening their mental workload capacity can help prevent occupational injuries in the workplace.

Objective Autism spectrum disorder (ASD) is a common disorder among children. The architectural design of the treatment environment can be effective in the quality of rehabilitation for these children. On the other hand, considering that an important part of treatment for children with ASD is to meet their sensory needs, there is a need for intervention and adaptation to the environment (sensory regime). The study aims to investigate the effect of the interior architecture of rehabilitation centers on the outcome of occupational therapy for children with ASD. Materials & Methods This is an observational cross-sectional study on 50 children with ASD aged 3-14 years, who were assigned into two groups of treatment in standard and non-standard environments, according to interior architectural factors. They were assessed before and after occupational therapy. To rank the physical space of rehabilitation centers, a researcher-made questionnaire was used with 30 criteria measuring natural light intensity, light quality (natural or artificial), visibility and view of the inside of the building, noise and visual pollution, and color of the walls. The criteria were based on the opinions of 32 occupational therapists and parents of 50 ASD children. The sensory profile 2 was used to measure sensory processing patterns (sensation seeking, sensation avoiding, sensory sensitivity, and sensory registration) of children with ASD. The paired t-test was used for within-group comparison, and the independent t-test was used for between-group comparison. Results Both standard and non-standard treatment environments were effective in improving all four patterns of sensory processing (P=0.04). However, the rehabilitation center with standard design had a more significant positive effect on all four sensory processing patterns, including sensation seeking (P=0.001), sensation avoiding (P=0.001), sensory sensitivity (P=0.01), and sensory registration (P=0.001) compared to the non-standard environment. Conclusion The interior architecture of rehabilitation centers has a significant positive effect on the sensory processing patterns of children with ASD, which can affect the quality of rehabilitation services. Therefore, it is recommended to optimize the interior architecture of rehabilitation centers for ASD children. [ABSTRACT FROM AUTHOR]

Objective Proper physical activities play an important role in reducing disease and mortality in old age, and is one of the main causes of active aging; however, the fear of falling is a barrier to having proper physical activity. Due to the difference between the elderly living in urban and rural areas regarding the risk factors of fear of falling and the amount and type of physical activity, this study aims to investigate and compare the fear of falling, physical activity, and activities of daily living (ADL) in the elderly living in urban and rural areas of Konarak County, Iran. Materials & Methods In this analytical cross-sectional study, 350 elderly people aged ≥60 years, who were under the coverage of comprehensive rural and urban health service centers in Konarak, Sistan and Baluchestan province (224 from rural areas and 126 from urban areas) were selected using a random sampling method and based on the inclusion and exclusion criteria. In addition to recording their demographic information, their fear of falling, physical activity, and ADL were measured by the Persian version of falls efficacy scale-international (FES-I), Rapid Assessment of Physical Activity (RAPA), ADL scale, and Instrumental ADL scale (IADL), respectively. Results The mean overall age of the elderly was 68.48±7.84 years (69.53±8.29 years in the rural group and 66.62±6.61 years in the urban group), and there was a significant difference between the two groups in terms of age (P<0.001). Pearson correlation test results showed that the FES-I score had a statistically significant negative relationship with the scores of ADL, IADL, and RAPA1 in total and in each group (P<0.001), but there was no statistically significant relationship between the FES-I score and the RAPA2 neither in total (P=0.40) and nor in rural (P=0.38) and urban (P=0.81) groups. Conclusion The fear of falling is significantly higher in the elderly living in rural areas of Konarak county compared to those living in urban areas. The RAPA1 and basic ADL of the elderly living in urban areas are higher compared to those living in rural areas, but there is no significant difference between them in RAPA2 and IADL. In addition, fear of falling has a significant relationship with physical activity of the elderly in overall and in rural and urban groups. [ABSTRACT FROM AUTHOR]

Objective Knee osteoarthritis is one of the most common musculoskeletal disorders affecting balance. It is also a risk factor for falling in older people. People with a history of falling, whether being injured or not, acquire a fear of potential falling, so they limit their functional activities, leading to decreased mobility, muscle weakness, and increased risk of falling in the future. Evaluating the relationship between balance and fear of falling in these patients can detect the disability mechanisms and falling and also help find more effective therapeutic methods for these patients. Some previous studies evaluated the stability of patients by clinical methods in static situations and related it to fear of falling. However, the walking stability of patients was not assessed by laboratory-based systems in previous studies. Therefore, we aimed to evaluate dynamic (during walking and based on the center of mass sways) and static stability (based on the center of pressure sways) and their relationship with falling risk in patients with knee osteoarthritis. Materials & Methods This is a descriptive cross-sectional study. A group of 15 subjects with mild to moderate knee osteoarthritis with a Mean±SD age of 50±3.22 years and 15 normal subjects with comparable age, height, and weight participated in this study. The subjects' standing stability was evaluated using a Kistler force plate based on mediolateral (ML) and anteroposterior (AP) displacements of the center of pressure. Also, the dynamic stability of the subjects was evaluated during walking and based on the center of massbase of support relationship in AP and ML directions. Kinematic data were collected using a motion analysis system with 7 high-speed cameras and a Kistler force plate. To model the body segments, the output of Qualisys track manager software was exported to Visual 3D software. Fear of falling was assessed by the native version of the fall efficacy scale (FES-I). The normal distribution of data was checked by the Shapiro-Wilk test. The independent samples t-test was used to compare the stability of patients and normal subjects. The Pearson correlation coefficient was used to evaluate the relationships between static and dynamic stability parameters and fear of falling in patients with knee osteoarthritis. Results Patients with knee osteoarthritis had less stability during standing and walking than healthy subjects (P<0.05). Moreover, based on the results of this study, there was a linear relationship between the center of body pressure (COP) excursions in the AP direction and the fear of falling scale. Still, it was not significant (r=0.416, P=0.123), and there was no correlation between the other COP parameters with FES (r=0, P>0.05). The correlations between mean center of mass (COM) excursion in AP and ML directions and FES were 0.309 and -0.123, respectively; however, these correlations were also not statistically significant (P>0.05). Conclusion Based on the results of this study, there is no significant relationship between static and dynamic stability of the patients with mild to moderate knee osteoarthritis (based on COP-COM variables) and the fall efficiency scale. So, it seems that to improve these patients' functional abilities, and the therapists must focus on the other parameters that affect the falling, such as reducing pain, improving proprioception, and enhancing muscle strength. It is suggested that future studies include a more varied age range of elderly people and evaluate all contributing factors in falling of patients with knee osteoarthritis (such as pain, proprioception, vision, and muscle strength) and also evaluate the stability of patients with both laboratory-based and clinical tests.

Objective Post-traumatic stress disorder (PTSD) is one of the anxiety disorders caused by a specific event, which can be catastrophic events (natural disasters, war, imprisonment in a forced labor camp) or everyday adversities (death of relatives, divorce, carrying bags). Since patients who have recovered from COVID-19 are exposed to such events, this research was conducted to determine the prevalence of PTSD in this group. Materials & Methods This study was cross-sectional. The statistical population included all patients who recovered from COVID-19 between November 2021 and February 2022 in Hamedan City, Iran; based on Krejcie and Morgan's sample size table, 185 patients were selected by simple random sampling method. The research tool was the demographic questionnaire and the Mississippi posttraumatic stress disorder questionnaire (Mississippi PTSD); the data were analyzed using the Mann-Whitney and Kruskal-Wallis tests. Results The results showed that the Mean±SD score of PTSD was 80.37±17.37 in the subjects who recovered from COVID-19. The relationship between the demographic variables of gender (P=0.01), education (P=0.039), occupation (P=0.24), marriage (P=0.62), age (P=0.048), weight (P=0.047), height (P=0.023) with PTSD were reported. Conclusion The results showed that 76.2% of people who recovered from COVID-19 were exposed to PTSD with moderate and high severity; therefore, techniques to reduce anxiety from the coronavirus are recommended.

Objective Multiple sclerosis (MS) is a disorder that involves the central nervous system. Cognitive impairments in patients with MS have a direct and significant impact on their performance in the activities of daily living, and hence their social participation is disrupted. Thus, exploring cognitive domains can help us make clinical decisions and interventions. To cognitively rehabilitate these people and estimate the relationship between cognitive performance (computer test and performance test) and the level of participation, we should examine the correlation between these two domains. This study aims to determine the correlation between social participation and two types of cognitive assessments: computerized and functional. Materials & Methods The present study was a cross-sectional study, and sampling was done by available sampling. The target population was patients with MS admitted to the MS center of Isfahan City, Iran, provided that they met the inclusion criteria in the winter of 2021. Forty-five patients with MS (9 males and 36 females) with an expanded disability status scale between 1 and 5 were selected by available sampling. To assess their cognitive performance, Cambridge neuropsychological test automated battery (CANTAB) and the Lowenstein occupational therapy cognitive assessment (LOCTA) functional test were used. Also, the community integration questionnaire (CIQ) was used to determine the level of participation. The data were then processed with SPSS. Results Based on the study results on the intensity and relationship between the measures, there is integration in targeted activities with all measures of LOTCA and CANTAB. This measure had a significant relationship with orientation, visual perception, and motor praxis from the LOTCA test and Delayed matching to sample test (DMS) from the CANTAB test. Notable results include a high correlation between home integration of the CIQ and the stocking of Cambridge test from CANTAB (r=0.353), and social integration of the CIQ with the DMS from CANTAB (r=0.538), integration in purposeful and productive activities of the CIQ with the motor proxy from LOTCA (r=0.422). Conclusion According to the results, both tests have a high correlation with the CIQ. So, computer test, which has a good correlation with participation, can be used alongside the performance test.

Objective Cerebral palsy refers to a group of postural and movement disorders that limit movements and can be related to a non-progressive disorder in the developing brain. The international classification of disability emphasizes the child's functional abilities and routine performance. Some classification tools have been developed to describe and evaluate child's functions in daily activities such as walking, manipulating objects, and everyday communication. The present study aimed to investigate the relationship between classification systems (gross motor function, manual ability, communication function, and eating and drinking ability) in children with cerebral palsy. Materials & Methods This study was performed by cross-sectional correlation method and of descriptive analytical type. Children with cerebral palsy aged 12-144 months were recruited by convenience sampling from patients referred to clinics and public and private rehabilitation centers in Tehran and Arak cities, Iran, in 2019-2020. After completing the demographic information questionnaire by the child's primary caregiver, the gross motor function classification system (GMFCS), manual ability classification system (MACS), Communication function classification system (CFCS), and eating and drinking ability classification system (EDACS) were completed by a child therapist. Results In the present study, 154 children with a Mean±SD age of 49.45±32.22 months participated. also, 87 children (56.5%) were boys, and 67(43.5%) were girls. According to GMFCS, the highest percentage distributions at levels II and IV were 31.2% and 26%, respectively. In other words, more than 57% of children were distributed in these two levels. According to MACS, the distributions of the highest percentages at levels II, III, and IV were 28.6%, 22.1%, and 20.8%, respectively. In other words, more than 70% of the children were distributed in these three levels. According to EDACS, the distribution of almost all levels was equal except the V level, with 4.3% having the lowest percentage. According to CFCS, the distribution of the highest percentage at levels V and IV was 23.5%. In examining the relationship between functional systems, significant relationships were observed in all cases: MACS and GMFCS, r=0.672; CFCS and GMFCS, r=0.581; EADCS and GMFCS, r=0.593; CFCS and MACS, r=0.555; EADCS and MACS, r=664; EADCS and CFCS, r=0. 547 (P<0.01). Conclusion It seems that children with more motor function limitations show more limitations in other performance classification systems, too. Of course, the number of studies in this field is limited and needs further investigation. [ABSTRACT FROM AUTHOR]

Objective Stuttering is a speech disorder that occurs with frequent and abnormal disruptions in speech, such as sound repetition, sound prolongation, and sound or airflow blockage. Despite the many theories, the cause of stuttering has not been entirely determined, and various factors have been proposed for its etiology. According to the vicious circle hypothesis, increased speech disfluency results from hypervigilance to speech. This study aimed to measure the effect of reduced attention on speech through verbal and non-verbal dual tasks among school children with stuttering. Furthermore, the effect of dual tasks on the severity of stuttering was investigated among them. Materials & Methods In this cross-sectional study, the participants included 39 children (5 girls, 12.8%) and (34 boys, 87.2%) aged 8-12 years (10.25±1.35) with developmental stuttering selected via convenience sampling from primary schools in districts four and eight and speech therapy clinics in Tehran, Iran. Dual tasks were designed using the Visual Basic program. During the study, four speech samples were recorded for each participant. The second and third samples were designed as a dual task (addition of verbal or non-verbal tasks), while the first and fourth samples were designed as a single task. The participant's severity of stuttering in each sample was calculated based on the number of stuttered syllables (SS%), and data were analyzed by SPSS 20 software. Given the non-normal distribution of data, the generalized linear model with the Generalized Estimating Equation (GEE) and Bonferroni test were used to determine the difference in stuttering severity among speech samples. Results The GEE results showed that the severity of stuttering was different among the four speech samples (P=0.015). The lowest and highest mean stuttering severity among the 39 participants pertained to the non-verbal dual task (14.85) and the single initial task (17.11), respectively. A pairwise comparison of stuttering severity showed that the mean severity in the final single task was significantly lower than in the single initial task (P<0.05). However, mean stuttering severity was not significantly different between verbal and non-verbal tasks (P>0.05). Conclusion The findings showed that stuttering severity reduces when children with stuttering perform dual tasks. In other words, focusing children's attention on verbal and non-verbal tasks while talking reduced their dysfluency. [ABSTRACT FROM AUTHOR]

Objective Down syndrome or trisomy 21 is one of the most common human chromosomal disorders that affect cognitive functions, communication and behavioral skills. At the macro level, various factors can contribute to the Down syndrome prevalence and mortality. This study aimed to investigate the association of health system functions with Down syndrome prevalence and mortality worldwide. Materials & Methods The study was a cross-sectional study conducted based on the secondary analysis of existing data in 2019. Data from 202 countries in six different regions (African Region [AFRO], Eastern Mediterranean Region [EMRO], European Region [EURO], South-East Asia Region [SEARO], Western Pacific Region [WPRO], and Pan American Health Organization [PAHO]) were included in the study. Data were extracted from the World Health Organization (WHO), the World Bank and the Institute for Health Metrics and Evaluation databases. The adjusted linear regression analysis was used to examine the association between health system-related factors with prevalence of, and death due to Down syndrome as the outcome variables. In the present study, two functions of health financing (domestic general government health expenditure [GGHE-D] per capita in PPP [purchasing power parity] int$, domestic private health expenditure [PHE-D] per capita in PPP int$, external health expenditure [EXT] per capita in PPP int$) and health system resources (nurse and midwifery personnel, generalist medical practitioners [GMP], specialist medical practitioners [SMP], pharmacists, dentists, physiotherapists) were included in the study as independent variables. We used the Stata software version 14 to analyze Results Africa and low-income countries had the highest deaths due to Down syndrome. On the other side, Europe and high-income countries had the highest prevalence of Down syndrome worldwide. According to the available data, Iran had a lower prevalence (29.31 vs 38.44 per 100,000 population) and higher deaths (0.34 vs 0.32 per 100,000 population) compared to high-income countries. The 20-year trend of prevalence of, and deaths due to Down syndrome in Iran has always been lower and higher than high-income countries, respectively. Linear regression analysis showed that GGHE-D per capita (β=0.385, P<0.001) and PHE-D per capita (β=0.354, P=0.02) could predict the prevalence of Down syndrome significantly in the study countries. On the other hand, nurse and midwifery personnel (β=-0.607, P=0.014) and number of SMP (β=0.420, P=0.025) were associated with increased deaths from Down syndrome in the included countries. Conclusion Our findings showed GGHE-D and PHE-D are associated with a higher prevalence of Down syndrome in health systems. On the other hand, health system resources (nurses and SMP) were the main predictors of death due to Down syndrome in the included countries. International organizations and governments need to monitor and improve the equitable access of vulnerable groups to health services in low-income countries. Improving health insurance coverage and equitable distribution of health resources is suggested to reduce deaths due to Down syndrome in Iran. [ABSTRACT FROM AUTHOR]

Background and Aim In modern life, emotional and social problems have taken the highest rank among mental illnesses. The present study aimed to provide a causal model for predicting children’s psychosocial problems based on parenting styles with an emphasis on the mediating role of social support. Methods & Materials The present research was a cross-sectional analytic study. The study population included parents of children (under 5 years old with behavioral-emotional problems) referred to the comprehensive health centers services in Pardis City, Iran, in 2020. Of whom, 230 people were selected by convenience sampling method. Measurement tools included parenting styles, social support, and socioemotional problems questionnaires. Structural equation modeling with SmartPLS software was used to analyze the data. Ethical Considerations This study was approved by the Ethics Committee of Science and Research Branch, Islamic Azad University (Code: 99527). Results The Mean±SD age of mothers was 32.87±7.87 years. Also, 60% of children were boys, and 40% were girls, with an Mean±SD age of 4.12±0.78 years. The Mean±SD scores of socioemotional problems, parenting styles, and social support were found to be 40.16±4.73, 152.23±18.10, and 34.66±6.49, respectively. The results of structural equation modeling showed that parenting styles had a significant role in predicting children’s socioemotional problems through social support mediation (P<0.05). Also, the fitting branches of the model showed the proper fit of the model through the composite reliability and the Cronbach alpha calculation. Conclusion The results of the present study emphasize the critical role of early childhood life and the need to focus on support facilities for mother-child couples at this age. Accordingly, providing psychological and supportive interventions for mothers with high stress can result in parental adjustment and mental health and, subsequently, the child’s normal development.

Objective Social isolation is one of the important concerns in the elderly population which can negatively affect their quality of life and health. The present study aims to determine the prevalence of social isolation among older adults aged 60 years and older in Tehran, Iran and find its associated factors. Materials & Methods This is a secondary analysis study on data obtained from a large cross-sectional study conducted on older adults in Tehran in 2020. The Persian version of lubben social network scale (LSNS-6) was used to measure social isolation. The demographic characteristics (age, gender, marital status, living arrangements, and number of children), socio-economic status (educational level, employment status, and household income) and health-related information (history of chronic diseases and use of assistive devices) were collected using a checklist. Data were analyzed in SPSS v. 23 software using multivariate logistic regression analysis. The significance level was set at. Results The data were related to 1280 older adults aged 60 years and older (Mean±SD age=70.97±8.07 years). The prevalence of social isolation was 30.8%. The results of chi-square test revealed that living arrangement (P<0.001, X²=46.93), marital status (P<0.001, X²=26.91), household income (P<0.001, X²=67.44), level of education (P<0.05, X²=20.26), employment status (P <0.001, X²=29.21), musculoskeletal problems (P<0.001, X²=15.47), respiratory problems (P<0.05, X²=10.43), vision problems (P<0.05, X²=4.4), hyperlipidemia (P<0.001, X²=13.53), and wearing glasses (P<0.05, X²=3.92) had significant association with social isolation. The regression analysis model could significantly predict social isolation (X²=188.35, P<0.001). The model revealed that being male (P<0.05, OR=1.7), living with spouse (P<0.05, OR=0.4), musculoskeletal disease (P<0.05, OR=1.42), diabetes (P<0.05, OR=1.41), household income (P<0.001, OR=5.82), being unemployed (P<0.001, OR=2.13), having hyperlipidemia (P<0.001, OR=0.58), and living in developed areas (P<0.001, OR=2.02) significantly predicted the social isolation. Conclusion There is a strong association between social isolation and some socio-economic, demographic-health related factors in older adults. Health policymakers and healthcare experts can develop the screening and prevention programs related to the mental and social health of older adults in Tehran, Iran in order to moderate and control these factors.

Objective This study aims to translate and cross-culturally adapt the University of California at Los Angles Activity Scale (UCLA) to Iranian samples and evaluate the reliability and validity of the Persian UCLA in candidates for knee replacement surgery. Materials & Methods In this cross-sectional study, cross-cultural adaptation was performed according to the international quality of life assessment protocol in three stages: standard forward translation, translation synthesis, and backward translation. The Persian UCLA, tegner activity scale (TAS), short-form health survey (SF-36) and international physical activity questionnaire (IPAQ) were completed by 103 participants (candidates for knee replacement surgery). The Persian UCLA questionnaire was re-completed by 66 participants in the retest session with an interval of 3-7 days. An intra-class correlation coefficient (ICC) was used to evaluate test-retest reliability. The standard error of measurement (SEM) was used to determine smallest detectable change (SDC) in scores. To evaluate convergent validity of the Persian UCLA, its correlation with TAS, SF-36, and IPAQ was assessed using Spearman's correlation test. The ceiling and floor effects were also calculated. Results In the Persian version, no special changes were made and no problem or ambiguity was reported by the respondents based on a pilot study. The type of activities mentioned in the original version was not changed either and none of the participants had difficulty understanding the items. The Mean±SD of UCLA scores were 2.98±1.37 in the test phase and 2.89±1.32 in the retest phase. Psychometric tests results showed acceptable test-retest reliability of the Persian UCLA (ICC=0.96, 95% CI=0.93-0.97). Given an SDC score of 0.50 at 95% confidence interval, it can be said that if the UCLA score be above or less than 0.50, there is an improvement or decline in the activity level of patients. Based on the results of Spearman correlation test, the Persian UCLA showed a strong correlation with TAS (rs=0.71, P<0.001), a moderate correlation with IPAQ (rs=0.58, P<0.001) and physical health summary component of SF-36 (rs=0.59, P<0.001), and a weak correlation with the mental health summary component of SF-36 (rs=0.39, P<0.001). The Persian UCLA questionnaire had no ceiling or floor effects. Conclusion The Persian version of the UCLA questionnaire has acceptable reliability and validity for Iranian candidates for knee replacement surgery. [ABSTRACT FROM AUTHOR]

Objective The first years of life are particularly important because vital developments occur in all development domains including motor, cognition, communication, and social-emotional. Early detection of developmental delays is essential in planning for early intervention. This study aims to standardize the score of bayley scales of infants and toddlers development-third edition (Bayley-III) for Iranian samples aged 1-42 months. Materials & Methods Participants included 1700 children divided into 17 age groups of 100 children. The normative information was based on a national sample representative of Iran's population for infants aged 1-42 months based on the 2011 national population and housing census. For each age group, the total raw scores of each Bayley-III subscale (cognition, receptive communication, expressive communication, fine motor, and gross motor) were converted to scaled scores with a Mean±SD of 10±3. The composite scores (cognition, language and motor domains) were obtained by summing up the scaled scores. The composite scores were scaled to a metric with Mean±SD of 100±15 ranged 40-160. Growth scores (ranged 200-800, with a Mean±SD 500±100), percentile ranks (ranged from 1-99, with 50 as the mean and median), and developmental age equivalent were also determined. Confidence intervals for all five subscales were also determined. To compare the development level of the US children (norm samples) and Iranian children, their mean raw scores in five subscales were compared for finding the difference in scores. Results The Bayley-III was performed on 1744 children aged 0-42 months, including 908 (52.1%) girls and 836 (47.9%) boys. In comparing the development level of Iranian and US children, it was found that the mean scores were significantly different in 28 age groups (P<0.05). In seven age groups, the US children's scores were higher (age groups <6 months), and in 21 age groups, the scores of Iranian children were higher (age groups >6 months). Conclusion For early detection and intervention of children with developmental delays, a test with a normalized score should be used in Iran. Using the US norm-based scores in Iranian children leads to inaccuracy in the early detection of children with developmental delays. [ABSTRACT FROM AUTHOR]

Background and Aim Considering the increasing use of dental implants in replacing lost teeth, the odds of failure over time in this treatment are inevitable, as with other dental treatments; thus, it requires careful and regular follow-up. Accordingly, the present study aimed to evaluate the awareness and attitude of general dentists about the follow-up of the dental implants to create baseline information to schedule future workshops concerning dental implants. Methods & Materials In this analytic cross-sectional study, 98 general dentists of Arak City, Iran were evaluated. Questionnaires were designed in 3 sections, as follows: demographic, awareness, and attitude. After checking the validity and reliability of the questionnaires, they were distributed among the research participants. The obtained data were analyzed using descriptive analysis, Chi-squared test, and Independent Samples t-tests. The significance level was considered 0.05. Ethical Considerations This article was approved by the Ethics Committee of Arak University of Medical Sciences (Code: IR.ARAKMU.REC.1397.283). Results The average score of awareness of the questionnaires was equal to 10.8 (based on the score of 0-19); the mean score of attitude was measured as 12.8 (based on the score of 7-21). Fifty-Three of the explored dentists had performed implant treatment, whose awareness and attitude toward implants follow-up were significantly higher than those of the dentists who did not perform such treatment (P=0.0001). Work experience presented no significant effect on the examined dentists’ awareness and attitude (P>0.05). Conclusion General dentists have low awareness and attitude about implant follow-up. Follow-up plays an important role in the long-term success of implant therapy; therefore, dental education/retraining programs should be reviewed in this field. [ABSTRACT FROM AUTHOR]

Background and Aim Ovarian cancer is among the most common cancers in women worldwide. CA125 is the most frequent biomarker used in the screening for ovarian cancer. CA125 has no high sensitivity and specificity as a screening test in the medical community; however, because of being simple and noninvasive, it is almost always requested for evaluation and ruling out cancer. It plays an important role in the treatment and post-treatment process, the prediction of prognosis, and the relapse of the disease. The present study aimed to determine the relationship between a high level of CA125 tumor marker and ovarian cancer by detecting spesivity, sensivity, positive and negative predictive values. Methods & Materials In this cross-sectional study, all cases undergoing CA125 test in Velayat Hospital in 2017-1028 were evaluated for having ovarian cancer. In addition, the CA125 level was compared between healthy individuals and patients with ovarian cancer. Finally, the obtained data were analyzed using SPSS. Ethical Considerations The present study was approved by the Qazvin University of Medical Sciences (Ethics Code: IR.QUMS.REC.1396.316). Results In this study, 35.3% of the study participants received a definite diagnosis of ovarian cancer. Generally, CA125 values were negative in 41.8% and positive in.58.2% of the study subjects. The sensitivity of the test was measured as 80.1%, the specivity as 53.6%, the positive predictive value equaled 48.4%, and the negative predictive value was measured as 83%. There was a significant relationship between age and the presence of ovarian cancer, and serum CA125 levels. Conclusion The present study suggested that age and the serum level of CA125 were statistically significant. Finally, CA125 levels were significantly related to ovarian cancer. It provided moderate specivity and specivity as well as low positive predictive value and high negative predictive value as a tumor marker; it is valuable for ruling out of tumor but not appropriate as a screening test.

Background The aging population is increasing rapidly; therefore, paying attention to the needs of older people is necessary. Sexual satisfaction, which is needed to feel happy, is often neglected in older women. Objective This study aims to evaluate the relationship between sexual satisfaction and mental health in older women. Materials and Methods In this analytical study with a cross-sectional design, 195 married women aged ≥60 years covered by urban and rural health centers of Guilan, Iran were recruited using a cluster sampling method. A demographic form, the 28-item General Health Questionnaire (GHQ-28) and a Sexual Satisfaction Questionnaire were completed by participants and collected data were analyzed in SPSS v. 22 software using descriptive statistics (frequency, mean, standard deviation, median), and Mann- Whitney U, Kruskal-Wallis and Spearman correlation tests. Results There was a significant relationship between sexual satisfaction and mental health in older women (P<0.0001). 51.2%, 27.7% and 21.08% of participants had low, moderate and high sexual satisfaction, respectively. Sexual satisfaction was directly related to monthly income (P<0.0001) and women’s and their husbands’ education (P<0.0001 and 0.006) while it was inversely related to physical illness (P=0.030), medication use (P=0.009), age (P<0.0001), number of children (P=0.022), and duration of marriage (P<0.0001). The median score of mental health in participants was 38 (ranging 24-53) and the percentage of participants with mental problems (79.4%) was higher than those without mental problems (20.6%). Conclusion Mental health and sexual satisfaction in older women are directly related to each other; therefore, providing effective and appropriate sexual care programs is recommended for them.

Background Poisoning is an important public health issue and causes high mortality rate each year worldwide. Having epidemiological information can lead to proper planning for its prevention and intervention. Objective This study aims to investigate the one-year prevalence and causes of poisoning in patients received pre-hospital emergency services in Ghaemshahr, Mazandaran, Iran. Materials and Methods This is a descriptive cross-sectional study. After reviewing the medical files of 12552 patients collected from the Medical Emergency and Accident Management Center in Ghaemshahr, Iran in 2016, 398 poisoned patients were found. Their data including age, gender, place of residence, agent and cause of poisoning, and received therapeutic interventions were extracted and recorded. Results Of 398 patients, 17.3% had received treatment; 271 (68.1%) were male and 127 (31.9%) were female. The most common cause of poisoning was abuse (58.1%); 58.3% of the poisonings were caused by the use of medications and the rest were non-medication poisonings. Tramadol (29.6%) was the most common medication that had caused poisoning. Among non-medication poisonings, the most common agent were substances (22.6%) and alcohol (13.1%). The most common route of exposure to poisoning agent (toxins) was by ingestion. Conclusion Due to the increasing abuse of substances and medications such as tramadol among young people and considering the high prevalence of intentional poisoning in young women, there are a need for psychological support, proper monitoring of medicine distribution, and creating social and recreational opportunities for the young people in Iran.

Background Attention to adolescent health is one of the Millennium Development Goals. Adolescent health planning to achieve an acceptable level of health and prevention of waste of capital should be based on attention to all aspects of health and performing needs assessment. Objective This study aims to determine the health needs of male adolescents in Iran and the factors associated with their needs. Materials and Methods This is a cross-sectional study. Participants were boys studying in the first and second year of high school in the fields of mathematics, experimental sciences, humanities, and technical sciences at public, non-profit, and gifted & talented schools in Rasht, Iran. The sampling was done using a multi-stage cluster sampling method. Data were collected by using a demographic form and the Male Adolescent Health Needs-Assessment Scale. Results The boys’ Mean±SD scores of physical, sexual, mental, and social health needs was 49.65±0.15, 11.39±0.12, 89.28±0.29 and 47.3±0.24, respectively. Majority of them obtained excellent scores in physical (76%) and mental health (94%) needs and a good score in social health (81.3%) need, while they earned a moderate score in sexual health need (57.8%). Liner regression analysis results showed that the physical health need of boys had a statistically significant relationship with the type of study school (P= 0.001); their sexual health need with age (P= 0.002), type of study school (P= 0.015), mother’s education (P= 0.025), and mother’s occupation (P= 0.005); their mental health need with the type of study school (P= 0.009), birth rank (P= 0.048), father’s job (P= 0.021), and mother’s job (P= 0.022); and their social health need with the type of study school (P= 0.001). Conclusion Most important health needs of male adolescents in Iran is sexual health need followed by social, physical and mental health needs. The most important factors related to their health needs are type of study school, mother’s job and education, birth rank, and father’s job. The results of this study can be effective and useful in designing and implementing need-based interventions to promote male adolescents’ health. [ABSTRACT FROM AUTHOR]

Background and Aim Non-syndromic hearing loss is a genetically heterogeneous disorder. Mutation in the GJB2 gene is a major cause of non-syndromic hearing loss in numerous countries. This study aimed to evaluate GJB2 mutations in 31 individuals with non-syndromic hearing loss Methods & Materials In this descriptive cross-sectional study, the required blood samples were collected from 31 individuals with non-syndromic hearing loss in Rasht and Bandar Anzali Cities, Gilan Province, Iran. After DNA isolation, the GJB2 gene was amplified by the PCR method and underwent sequencing. Ethical Considerations This study was approved by the Ethics Committee of the Islamic Azad University, Mashhad Branch (Code: IR.IAU.MSHD.REC.1398.027). Results In this study, 3 mutations were determined in 18 individuals with hearing loss. Accordingly, 35delG mutation had the highest frequency (48.38%) in individuals with hearing loss as homozygote (n=14) and heterozygote (n=2). A patient with heterozygosity in V153I mutation and a patient with compound heterozygosity in 35delG/G200R mutation was determined. Conclusion It appears that 35delG mutation is a common mutation in the GJB2 gene in individuals with non-syndromic hearing loss in Guilan Province. [ABSTRACT FROM AUTHOR]
