Factors affecting ethical behavior in pediatric occupational therapy: A qualitative study

Background: It is the responsibility of each occupational therapist to always act ethically and professionally in a clinical setting. However, there is little information available concerning the factors influencing ethical behavior of occupational therapists at work. Since no study has been conducted in Iran on this topic, this qualitative study aimed to identify the factors influencing ethical behavior of pediatric occupational therapists. Methods: Twelve pediatric occupational therapists participated in this study. The sampling was purposeful, and the interviews continued until reaching data saturation. All interviews were recorded and transcribed. The data were analyzed by qualitative content analysis, and the ethics of qualitative research was considered. Results: The factors influencing ethical behavior were classified into four main categories including organizational factors, therapist related factors, client's family issues, and social factors. Conclusion: This study identified numerous factors influencing the ethical behavior of pediatric occupational therapists that could be used to train occupational therapists, human resources managers, professional policy makers, and could also be used to conduct future researches, and produce tools

Prevention of malnutrition among children under 5 years old in Iran: A policy analysis

Background Malnutrition is one of the main causes of death in children under 5 years of age and one of the most common factors threatening children�s life and health. Nutrition policy analysis and solving existing problems in children can reduce the effects of malnutrition. This study aimed to analyze the current policies of malnutrition prevention in children under five years of age in Iran. Method This study was conducted in 2017 to analyze policies using the "policy triangle framework". In order to examine the policy-making process, the Kingdon�s multiple streams model was used. A combination of two sampling methods, including purposeful and snowball sampling, was applied to select the interviewees. In relation to the implemented documents and policies, the country�s most important policies were selected based on the suggestions of policy makers as well as searching scientific databases and electronic portals. A data collection form was used to identify the current policies and documents and a semi-structured interview guide form was used for the interviews. The framework analysis and MaxQDA software were applied to analyze the data obtained from the interviews. Results The key factors affecting policies in Iran included the status of indicators as well as economic, social, structural-legal, policy and international factors. Among the most important policies and implemented programs, the following can be mentioned: growth monitoring, oral rehydration, breastfeeding, immunization, female education, family spacing, food supplementation, nutrition for children under five years of age, and control of nutritional deficiencies. Currently there is a need for a nationwide program and comprehensive document in the field of the nutrition in children under 5 years of age, which requires strengthening of the political process. Participants and stakeholders in nutrition-related policies for children under the age of five were divided into four categories of governmental, semi-governmental, non-governmental, and international organizations. Conclusion More attention should be paid to the shortage of some micronutrients, accurate implementation of breastfeeding programs, supplementary nutrition, fortification and supplementation programs for children and mothers, utilization of the advantages of each region and its resources, and better coordination between organizations and their policies, and finally strong incentives are needed to promote macro nutritional goals for children under five years of age. © 2019 Mohseni et al.

The prevalence of adulthood overweight and obesity in Tehran: Findings from Urban HEART-2 study

Background: To estimate and compare prevalence of overweight and obesity among adult people across the 22 districts of Tehran in 2011. Methods: This was a cross-sectional study using data on 47,406 women and 47,525 men aged� 15 years from a large population-based survey (Urban HEART-2). Age-standardized prevalence (ASP) of overweight (25�BMI<30) and obesity (BMI�30) were estimated for the Tehran's districts. Pearson Chi2 tests and logistic regression were used to examine any significant differences in prevalence of these disorders across sociodemographic groups. Results: ASPs of overweight were 36.5 and 32.0 among men and women, respectively (p<0.001). These figures for obesity were 10.7 and 15.3 among men and women, respectively (p<0.001). Crude prevalence of overweight and obesity rose with age up to the age of 54 years and decreased thereafter. Across education groups, the lowest prevalence of overweight/obesity was seen among most educated people. The results showed that being young, single and student were associated with lower odds of overweight/obesity. Conclusion: This study showed a high prevalence of overweight and obesity among adult in Tehran. There were significant associations between sociodemographic characteristics and prevalence of overweight/obesity among adults in Tehran. The results of this study might be used in identifying high risk groups of overweight and obesity in Tehran

Arctic wetland system dynamics under climate warming

Warming and hydrological changes have already affected and shifted environments in the Arctic. Arctic wetlands are complex systems of coupled hydrological, ecological, and permafrost-related processes, vulnerable to such environmental changes. This review uses a systems perspective approach to synthesize and elucidate the various interlinked responses and feedbacks of Arctic wetlands to hydroclimatic changes. Starting from increased air temperatures, subsequent permafrost thaw and concurrent hydrological changes are identified as key factors for both shrinkage and expansion of wetland area. Other diverse factors further interact with warming, hydrological changes, and permafrost thaw in altering the Arctic wetland systems. Surface albedo shifts driven by land cover alterations are powerful in reinforcing Arctic warming, while vegetation-related factors can balance and decelerate permafrost thaw, causing negative feedback loops. With the vast amounts of carbon stored in Arctic wetlands, their changes in turn affect the global carbon cycle. Overall, the systems perspectives outlined and highlighted in this review can be useful in structuring and elucidating the interactions of wetlands with climate, hydrological, and other environmental changes in the Arctic, including the essential permafrost-carbon feedback.

Measurements of scattering observables for the pdpd break-up reaction

High-precision measurements of the scattering observables such as cross sections and analyzing powers for the proton-deuteron elastic and break-up reactions have been performed at KVI in the last two decades and elsewhere to investigate various aspects of the three-nucleon force (3NF) effects simultaneously. In 2006 an experiment was performed to study these effects in $\vec{p}+d$ break-up reaction at 135 MeV with the detection system, Big Instrument for Nuclear polarization Analysis, BINA. BINA covers almost the entire kinematical phase space of the break-up reaction. The results are interpreted with the help of state-of-the-art Faddeev calculations and are partly presented in this contribution.Comment: Proceedings of 19th International IUPAP Conference on Few-Body Problems in Physics, Bonn University, 31.08 - 05.09.2009, Bonn, GERMAN

Evaluation of suspicious appearing microcalcification groups on mammogram: Comparing BI-RADS 5th edition descriptors with the BI-RADS 4th edition and pathologic association

Background: Groups of microcalcifications are the most frequent recognized features of ductal carcinoma on mammograms. However, heterogeneity (in size, morphology and density) and number of microcalcification groups as well as presence of accompanied soft-tissue density are not included in breast imaging reporting and data system (BI-RADS) descriptors. Objectives: The study purposes to determine the malignancy risk of microcalcification groups regarding these characteristics and also compare the 4th and 5th versions of BI-RADS. Patients and Methods: In a cross sectional study, 88 patients with microcalcification groups (age range, 26-80 years; mean, 53.4 years) who had undergone mammographically guided biopsy between March 2013 and March 2015 were evaluated. The overall number of microcalcification groups in each patient, number of deposits within each group, group location and heterogeneity in size, density and morphology were assessed and subsequently BI-RADS descriptors for 4th and 5th editions were recorded separately. Finally, correlation with histopathology was performed. Results: Overall, positive predictive value (PPV) of suspicious microcalcifications was 22.4. PPVs of morphology descriptors were as follows: amorphous, 7.9; coarse heterogeneous, 17.8; fine pleomorphic, 63.2; fine linear/fine linear branching, 100; (P < 0.001). Heterogenicity in size existed in 81 cases (92), in density in 69 cases (86.4) and in morphology in 86 cases (97.7). Additionally, microcalcification groups that were accompanied with soft-tissue density had a higher percentage of malignancy (67.5 vs. 54.5) but with no significant difference (P = 0.2). According to BI-RADS 4th edition, the risk of malignancy was 49.1, 66.7 and 88.1 in 4b, 4c and 5, respectively. These figures were 30, 82.9, and 100 for BI-RADS 5th version, respectively. The area under the receiver (AUC) of 4th and 5th versions of BI-RADS was 0.76 and 0.74 (both P values < 0.001, 95 confidence intervals = 0.66-0.87 and 0.63-0.85 respectively). P value for comparison was insignificant. Conclusion: The risk of malignancy increased with the heterogeneity of microcalcifications, especially in the groups with heterogeneity in density, however with no statistically significant difference. BI-RADS 5th edition could predict the likelihood of malignancy as well as 4th version. © 2018, Iranian Journal of Radiology
