Soil Microorganisms and Seaweed Application With Supplementary Irrigation Improved Physiological Traits and Yield of Two Dryland Wheat Cultivars.

To evaluate the effect of useful soil microorganisms and organic compounds on physiological characteristics and yield of two wheat cultivars under supplementary irrigation conditions, a study was conducted in the Agriculture Research Farm of Kurdistan University during the two cropping seasons of 2017-2018 and 2018-2019. A split-split plot-based study on a randomized complete block design with four replicates was used as an experimental design. The main factor was irrigation at three levels, including control without irrigation, supplementary irrigation in the booting stage, and supplementary irrigation in the booting and flowering stages. Two wheat cultivars, namely, Sardari and Sirvan, as sub-factors and application of bio-fertilizers in eight levels, including the use of bio-fertilizers containing: Mycorrhiza, Seaweed extract, Nitrozist and Phosphozist, Mycorrhiza + Nitrozist and Phosphozist, Seaweed extract + Nitrozist and Phosphozist, Mycorrhiza + Seaweed extract, Mycorrhiza + Nitrozist and Phosphozist + Seaweed extract, and non-application of bio-fertilizers, were considered as sub-factors. The results of both seasons of the experiment showed that the application of bio-fertilizers compared to the control treatment at all irrigation levels increased root volume, leaf relative water content (RWC), membrane stability index (MSI), and photosynthetic pigment content. The highest amount of H2O2, proline, and soluble carbohydrates were obtained in wheat under dry land conditions, and supplementary irrigation, especially two-time irrigation, significantly reduced the values of these traits. Supplementary irrigation also increased grain yield, so that in the conditions of two-time irrigation compared to the non-irrigation treatment (dry land), in the first and second seasons, the grain yield increased by 79.51 and 78.69%, respectively. Application of bio-fertilizers (Mycorrhiza + Nitrozist and Phosphozist + Seaweed extract) in comparison with the non-application of these fertilizers, due to increased root volume, RWC, MSI, and content of photosynthetic pigments, increased the grain yield in the first and second seasons of the experiment by 8.04 and 6.96%, respectively. As a result, suitable microorganisms and seaweed can improve wheat resistance mechanisms to water deficit, which along with using supplementary irrigation that saves water consumption improves plant growth and yield in areas faced with water shortage.

Salicylic Acid Stimulates Defense Systems in Allium hirtifolium Grown under Water Deficit Stress.

Nowadays, the use of the growth regulator salicylic acid for improving a plant's resistance to environmental stresses such as drought is increasing. The present study investigated the effect of salicylic acid on the physiological traits, antioxidant enzymes, yield, and quality of Allium hirtifolium (shallots) under drought conditions for three years (2016-2017, 2017-2018, and 2018-2019). The experiment was conducted as a split-plot based on a randomized complete block design with four repeats. Irrigation as the main factor in four levels of 100% (full irrigation), 75% and 50% of the plant water requirements with non-irrigation (dryland), and salicylic acid as the sub-factor in four levels of 0, 0.75, and 1 mmol, were the studied factors in this research. The combined analysis of three-year data showed that drought reduced leaf relative water content (RWC), membrane stability index (MSI), chlorophyll content, onion yield, and increased activity of antioxidant enzymes, proline content, tang, and allicin of shallots. Shallot spraying with salicylic acid improved leaf RWC, MSI, chlorophyll content, and onion yield. The highest yield of onion (1427 gr m-2) belonged to full irrigation and foliar application of 1 mmol salicylic acid. The lowest yield (419.8 gr m-2) belonged to plats with non-irrigation and non-application of salicylic acid. By improving the effective physiological traits in resistance to water deficit, salicylic acid adjusted the effects of water deficit on the yield of shallots. Foliar application of 1 mmol salicylic acid in dryland and irrigation of 50% of the plant water requirement increased onion yield by 15.12% and 29.39%, respectively, compared to the control treatment without salicylic acid.

The association of cardio-metabolic risk factors and history of falling in men with osteosarcopenia: a cross-sectional analysis of Bushehr Elderly Health (BEH) program.

BACKGROUND: Osteosarcopenia, defined as sarcopenia plus osteopenia/osteoporosis, may increase the risk of fractures and affects morbidity and mortality in the older population. Falling is also common in the elderly and increases the risk of fractures and mortality. We examined the association of cardio-metabolic risk factors with a history of falling in osteosarcopenic men. METHODS: We used the baseline data of the Bushehr Elderly Health (BEH) program. Osteosarcopenia was defined as having both sarcopenia (reduced skeletal muscle mass plus low physical performance and/or low muscle strength) and osteopenia/osteoporosis (T-score ≤ - 1.0). Falling was defined as a self-reported history of an unintentional down on the ground during the previous year before the study. We used logistic regression analysis to estimate the adjusted odds ratio (AOR) with a 95% Confidence Interval (CI) to quantify the associations. RESULTS: All elderly men diagnosed with osteosarcopenia (n = 341), with a mean age of 73.3(±7.4) years, were included. Almost 50(14.7%) participants reported falling. Age showed a positive association with falling (AOR: 1.09, 95%CI: 1.04-1.14). An increase of 10 mmHg in systolic blood pressure(SBP), reduces the odds of falling by 26%(AOR:0.74, 95%CI:0.62-0.89), while a positive association was detected for fasting plasma glucose (FPG), as 10 mg/dl increase in the FPG, raises the chance of falling by 14%(AOR = 1.14, 95%CI:1.06,1.23). Hypertriglyceridemia was inversely associated with falling (AOR = 0.33, 95% CI: 0.12, 0.89). CONCLUSIONS: Falling is a major public health problem in rapidly aging countries, especially in individuals with a higher risk of fragility fractures. Older age-raised fasting plasma glucose and low SBP are associated with falling in osteosarcopenic patients.  Considering the higher risk of fracture in osteosarcopenic men, comprehensive strategies are needed to prevent fall-related injuries in this high-risk population.

Responses of Soil Microbial Biomass and Enzyme Activities to Tillage and Fertilization Systems in Soybean (Glycine max L.) Production.

Tillage operation and fertilizer type play important roles in soil properties as far as soil microbial condition is concerned. Information regarding the simultaneous evaluation of the effect of long-term tillage and fertilization on the soil microbial traits of soybean farms is not available. Accordingly, it was hypothesized that, the microbial biomass and enzyme activity, more often than not, respond quickly to changes in soil tillage and fertilization. Therefore, the experiments were aimed at analyzing the responses of soil microbial traits to tillage and fertilization in a soybean field in Kurdistan University, Iran. The field soil is categorized into coarse Loamy, mixed, superactive, calcareous, and mesic Typic Xerorthents. The experiments were arranged in split plot, based on randomized complete block design with three replications. Main plots consisted of long-term (since 2002) tillage systems including conventional tillage (CT), minimum tillage (MT), and no-tillage (NT). Eight fertilization methods were employed in the sub-plots, including (F1): farmyard manure (FYM); (F2): compost; (F3): chemical fertilizers; (F4): FYM + compost; (F5): FYM + chemical fertilizers; (F6): compost + chemical fertilizers; (F7): FYM + compost + chemical fertilizers and (F8): Control (without fertilizer). The highest microbial biomass carbon (385.1 µg) was observed in NT-F4 treatment. The NT treatment comparatively recorded higher values of acid phosphatase (189.1 µg PNP g-1 h-1), alkaline phosphatase (2879.6 µg PNP g-1 h-1) and dehydrogenase activity (68.1 µg PNP g-1 h-1). The soil treated with a mixture of compost and FYM inputs had the maximum urease activity of all tillage treatments. Organically manured treatment (F4) showed more activity in dehydrogenase (85.7 µg PNP g-1 h-1), acid phosphatase (199.1 µg PNP g-1 h-1), and alkaline phosphatase (3183.6 µg PNP g-1 h-1) compared to those treated with chemical fertilizers. In NT-F4 treatment, using on-farm inputs is most suitable for sustainable management and improvement in soil biological activities in soybean cultivation. We concluded that applying organic manures and employing reduced tillage systems increased soil microbial biomass and enzyme activities.

A randomized controlled trial of smoking cessation methods in patients newly-diagnosed with pulmonary tuberculosis.

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

Policy makers' viewpoints on implementation of the World Health Organization Framework Convention on Tobacco Control in Iran: A qualitative investigation of program facilitators.

BACKGROUND: The epidemic of smoking is a great concern of health systems. Moreover, the number of smokers is increasing worldwide and this has led to an escalating trend of morbidity, mortality, and burden of smoking-related diseases. Therefore, monitoring the implementation of tobacco control laws in different countries is of extreme importance. This study aimed to describe policy makers' experiences and perceptions of the facilitating factors of the implementation of the World Health Organization Framework Convention on Tobacco Control (WHO FCTC) in Iran. METHODS: This was a qualitative research in which data were collected through individual interviews. The participants included policy makers who were members of the national assembly for tobacco control. In this study, 13 unstructured interviews of about 45 to 60 minutes duration were conducted in an extrapolative manner. The qualitative content analysis method was applied until extrapolation of basic themes was complete. RESULTS: As a result of the analysis, the themes of performance through training, through research, through intersectoral collaboration, and through setting priorities emerged. The emerged themes connote some critical points that have key roles in promoting the effective implementation of the WHO FCTC. Furthermore, the main role of the health sector becomes predominant. CONCLUSION: The study findings suggested the managed and coordinated work as one of the main facilitating factors of the implementation of the WHO FCTC at a national level.

Bushehr Elderly Health (BEH) Programme, phase I (cardiovascular system).

PURPOSE: The main objective of the Bushehr Elderly Health Programme, in its first phase, is to investigate the prevalence of cardiovascular risk factors and their association with major adverse cardiovascular events. PARTICIPANTS: Between March 2013 and October 2014, a total of 3000 men and women aged ≥ 60 years, residing in Bushehr, Iran, participated in this prospective cohort study (participation rate=90.2%). FINDINGS TO DATE: Baseline data on risk factors, including demographic and socioeconomic status, smoking and medical history, were collected through a modified WHO MONICA questionnaire. Vital signs and anthropometric measures, including systolic and diastolic blood pressure, weight, height, and waist and hip circumference, were also measured. 12-lead electrocardiography and echocardiography were conducted on all participants, and total of 10 cc venous blood was taken, and sera was separated and stored at -80 °C for possible future use. Preliminary data analyses showed a noticeably higher prevalence of risk factors among older women compared to that in men. FUTURE PLANS: Risk factor assessments will be repeated every 5 years, and the participants will be followed during the study to measure the occurrence of major adverse cardiac events. Moreover, the second phase, which includes investigation of bone health and cognition in the elderly, was started in September 2015. Data are available at the Persian Gulf Biomedical Research Institute, Bushehr University of Medical Sciences, Bushehr, Iran, for any collaboration.

Do Iranian tobacco growers support the World Health Organization framework convention on tobacco control?

CONTEXT: Studies on the World Health Organization Frame-work Convention on Tobacco Control (FCTC) are scarce in Iran and the Eastern Mediterranean region (EMR). AIM: This study was conducted in 2007-2008 in Iran to design a practical evaluation model of the implementation of FCTC with the potential to be adopted in the EMR. Given that, the findings of this evaluation can be useful in increasing political and public support for enforcing the implementation of legislations, testing their feasibility, and maintaining sustainability. The viewpoints of tobacco growers as part of stakeholders in this regardwould have an influential role. SETTINGS AND DESIGN: This study was a qualitative one to investigate the tobacco growers viewpoints about thestrengths/weaknesses of FCTC implementation in Iran. MATERIALS AND METHODS: In this study, we conducted semi-structured in-depth individual interviews with 5 tobacco growers. All interviews were carried out with their permissionwere recorded and were assured that their interviews will be kept confidential. All questions were related to different FCTC articles, then written transcripts were prepared and the basic concepts were extrapolated. STATISTICAL ANALYSIS: After transcribing the recorded interviews, we extracted first level codes and main concepts from them. RESULTS: The findings suggested that although tobacco growers agreed with FCTC implementation, however, subjects like the necessity to support tobacco growers and obtaining insurance from the government, the necessity of the enforcement of national tobacco control law and planning to decrease access to tobacco by policy makers were the most key points that tobacco growers pointed to them. CONCLUSION: Our results showed that tobacco growers agreed with the implementation of FCTC but they worried about their job and the expenses of their daily life. Therefore, it seems that policy makers have to design a plan to support tobacco growers for changing tobacco with a safe cultivate.

Serum retinol levels are positively correlated with hemoglobin concentrations, independent of iron homeostasis: a population-based study.

Micronutrient interactions give rise to complex issues that have an impact on preventive strategies when multiple micronutrient deficiencies coexist. The aim of this population-based study was to determine the prevalence of vitamins A and E and iron deficiencies among women 15 to 49 years of age in the northern Persian Gulf region. We hypothesized that serum retinol levels may show correlations with hemoglobin (Hb) concentrations, independent of iron status. A total of 1242 nonpregnant women of reproductive age were selected via a multistage stratified random cluster sampling technique. Serum ferritin and soluble transferrin receptor levels were measured using enzyme immunoassay techniques. Serum retinol (vitamin A) and α-tocopherol (vitamin E) were determined for 727 women by high-performance liquid chromatography. The prevalence of anemia (Hb <12 g/dL), iron deficiency (serum ferritin <15 µg/L), and iron deficiency anemia was 8.7%, 25.4%, and 4.6%, respectively. Vitamin A (<0.7 µmol/L) and vitamin E (<11.6 µmol/L) deficiencies were found in 1.2% and 5.9% of the studied population, respectively. Multiple regression analysis revealed that serum retinol levels exhibit a significant association with Hb concentrations after controlling for serum ferritin levels, anemia associated with chronic disease, and risk factors for anemia. Therefore, most nonpregnant women of reproductive age in the northern Persian Gulf were found to have adequate serum vitamin A and E levels. However, the status of anemia and iron deficiency anemia could be considered a mild public health problem in this region. On the basis of multivariate analyses, we conclude that low serum retinol levels may contribute to anemia, independent of iron homeostasis.

The experience of community health workers training in Iran: a qualitative study.

BACKGROUND: The role of Community Health Workers (CHWs) in improving access to basic healthcare services, and mobilising community actions on health is broadly recognised. The Primary Health Care (PHC) approach, identified in the Alma Ata conference in 1978, stressed the role of CHWs in addressing community health needs. Training of CHWs is one of the key aspects that generally seeks to develop new knowledge and skills related to specific tasks and to increase CHWs' capacity to communicate with and serve local people. This study aimed to analyse the CHW training process in Iran and how different components of training have impacted on CHW performance and satisfaction. METHODS: Data were collected from both primary and secondary sources. Training policies were reviewed using available policy documents, training materials and other relevant documents at national and provincial levels. Documentary analysis was supplemented by individual interviews with ninety-one Iranian CHWs from 18 provinces representing a broad range of age, work experience and educational levels, both male and female. RESULTS: Recognition of the CHW program and their training in the national health planning and financing facilitates the implementation and sustainability of the program. The existence of specialised training centres managed by district health network provides an appropriate training environment that delivers comprehensive training and increases CHWs' knowledge, skills and motivation to serve local communities. Changes in training content over time reflect an increasing number of programs integrated into PHC, complicating the work expected of CHWs. In-service training courses need to address better local needs. CONCLUSION: Although CHW programs vary by country and context, the CHW training program in Iran offers transferable lessons for countries intending to improve training as one of the key elements in their CHW program.

Contrasting soil microbial responses to fertilization and tillage systems in canola rhizosphere.

Information regarding the simultaneous evaluation of tillage and fertilization on the soil biological traits in canola production is not available. Therefore, field experiments were conducted in 2007-2010 in a split plot based on randomized complete block design with three replications. Main plots consisted of conventional tillage (CT); minimum tillage (MT) and no tillage (NT). Six strategies of fertilization including (N1): farmyard manure (cattle manure); (N2): compost; (N3): chemical fertilizers; (N4): farmyard manure + compost; (N5): farmyard manure + compost + chemical fertilizers and (N6): control, were arranged in sub plots. Results showed that the addition of organic manure increased the soil microbial biomass. No tillage system increased microbial biomass compared to other tillage systems. The activities of all enzymes were generally higher in the N4 treatment. The activity of phosphatase and urease tended to be higher in the no tillage treatment compared to the CT and MT treatments.

A comprehensive model to evaluate implementation of the world health organization framework convention of tobacco control.

BACKGROUND: Iran is one of the countries that has ratified the World Health Organization Framework Convention of Tobacco Control (WHO-FCTC), and has implemented a series of tobacco control interventions including the Comprehensive Tobacco Control Law. Enforcement of this legislation and assessment of its outcome requires a dedicated evaluation system. This study aimed to develop a generic model to evaluate the implementation of the Comprehensive Tobacco Control Law in Iran that was provided based on WHO-FCTC articles. MATERIALS AND METHODS: Using a grounded theory approach, qualitative data were collected from 265 subjects in individual interviews and focus group discussions with policymakers who designed the legislation, key stakeholders, and members of the target community. In addition, field observations data in supermarkets/shops, restaurants, teahouses and coffee shops were collected. Data were analyzed in two stages through conceptual theoretical coding. FINDINGS: Overall, 617 open codes were extracted from the data into tables; 72 level-3 codes were retained from the level-2 code series. Using a Model Met paradigm, the relationships between the components of each paradigm were depicted graphically. The evaluation model entailed three levels, namely: short-term results, process evaluation and long-term results. CONCLUSIONS: Central concept of the process of evaluation is that enforcing the law influences a variety of internal and environmental factors including legislative changes. These factors will be examined during the process evaluation and context evaluation. The current model can be applicable for providing FCTC evaluation tools across other jurisdictions.

A policy review of the community health worker programme in Iran.

Iran's Community Health Worker (CHW) programme survived as an integral element of the health system during a period when many other nations' CHW programmes collapsed and therefore warrants detailed analysis of the policies supporting the programme. We draw on a wide range of information about the Iranian programme and from this analysis draw important lessons on how to improve rural population health outcomes through Primary Health Care.

Training evaluation: a case study of training Iranian health managers.

BACKGROUND: The Ministry of Health and Medical Education in the Islamic Republic of Iran has undertaken a reform of its health system, in which-lower level managers are given new roles and responsibilities in a decentralized system. To support these efforts, a United Kingdom-based university was contracted by the World Health Organization to design a series of courses for health managers and trainers. This process was also intended to develop the capacity of the National Public Health Management Centre in Tabriz, Iran, to enable it to organize relevant short courses in health management on a continuing basis. A total of seven short training courses were implemented, three in the United Kingdom and four in Tabriz, with 35 participants. A detailed evaluation of the courses was undertaken to guide future development of the training programmes. METHODS: The Kirkpatrick framework for evaluation of training was used to measure participants' reactions, learning, application to the job, and to a lesser extent, organizational impact. Particular emphasis was put on application of learning to the participants' job. A structured questionnaire was administered to 23 participants, out of 35, between one and 13 months after they had attended the courses. Respondents, like the training course participants, were predominantly from provincial universities, with both health system and academic responsibilities. Interviews with key informants and ex-trainees provided supplemental information, especially on organizational impact. RESULTS: Participants' preferred interactive methods for learning about health planning and management. They found the course content to be relevant, but with an overemphasis on theory compared to practical, locally-specific information. In terms of application of learning to their jobs, participants found specific information and skills to be most useful, such as health systems research and group work/problem solving. The least useful areas were those that dealt with training and leadership. Participants reported little difficulty in applying learning deemed "useful", and had applied it often. In general, a learning area was used less when it was found difficult to apply, with a few exceptions, such as problem-solving. Four fifths of respondents claimed they could perform their jobs better because of new skills and more in-depth understanding of health systems, and one third had been asked to train their colleagues, indicating a potential for impact on their organization. Interviews with key informants indicated that job performance of trainees had improved. CONCLUSION: The health management training programmes in Iran, and the external university involved in capacity building, benefited from following basic principles of good training practice, which incorporated needs assessment, selection of participants and definition of appropriate learning outcomes, course content and methods, along with focused evaluation. Contracts for external assistance should include specific mention of capacity building, and allow for the collaborative development of courses and of evaluation plans, in order to build capacity of local partners throughout the training cycle. This would also help to develop training content that uses material from local health management situations to demonstrate key theories and develop locally required skills. Training evaluations should as a minimum assess participants' reactions and learning for every course. Communication of evaluation results should be designed to ensure that data informs training activities, as well as the health and human resources managers who are investing in the development of their staff.

Effect of salinity on growth and yield of Desi and Kabuli chickpea cultivars.

To evaluate the effects of different level of Na salinity (0, 3, 6 and 9 dS m(-1)) on growth, yield and yield component of Kabuli (Hashem and Jam) and Desi (Kaka and Pirooz) chickpea cultivars a factorial experiment based on randomized complete block design with four replications was carried out in Research Greenhouse of Mokrian Agricultural Extension Center near Mahabad, Iran at 2006. Seeds of four chickpea cultivars were grown under 0, 3, 6 and 9 dS m(-1) levels of salinity until maturity. Salinity reduced the plant growth, flower, pod and seed number and seed weight. As increase in salinity, the undesirable effect of Na+ was more pronounced and reached the highest value at 9 dS m(-1) in all cultivars. Four chickpea cultivar have different responses to salinity and the Kabuli cultivars seemed to have a greater capacity for salt tolerance compared to Desi cultivars. Hahshem cultivar has the highest salinity tolerance among all cultivars.

A school-based intervention to teach 3-4 grades children about healthy heart; the Persian Gulf healthy heart project.

BACKGROUND: Cardiovascular health promotion in children has the potential to reduce the risk of atherosclerosis in both the individual child and the population at large. It thus seems eminently reasonable to initiate healthful lifestyle training in childhood to promote improved cardiovascular health in adult life. AIMS: To test the hypothesis that a year long, classroom-based education for the third and fourth graders could change their knowledge scores about healthy heart. SETTINGS AND DESIGN: A randomized, controlled trial in elementary schools of Bushehr/Iran. METHODS AND MATERIALS: A total of 14 elementary schools, categorized by socioeconomic types and male and female setting were selected and randomized into control or intervention groups. Subjects were 1128 third and fourth graders, aged 9 to 10 years (49.1% boys and 50.9% girls). Over a course of 8 weeks, health educators and sport teachers of the elementary schools presented two hours sessions per week on heart function, nutrition, and exercise for healthy heart and living tobacco free for the intervention group. The education program was based on HeartPower! Program, an American Heart Association program. STATISTICAL ANALYSIS: Mann-Whitney U test and Wilcoxon matched-pairs signed rank test and Bonferroni correction for the two pair wise comparisons were used. RESULTS: Total heart knowledge at posttest was 25% correct higher in the intervention than in the control group (p< 0.001). Difference in means of total healthy heart knowledge scores between control and intervention group increased from 1.43 points in baseline to 4.02 points in posttest (p< 0.001). CONCLUSION: It can be concluded that the classroom-based cardiovascular health promotion had a significant effect on the heart healthy knowledge. Therefore, schools provide an excellent setting for introducing comprehensive healthy heart education and promotion of cardiovascular health to the general population.
