How farmers perceive the impact of dust phenomenon on agricultural production activities : a Q-methodology study

Dust as one of the environmental concerns during the past decade has attracted the attention of the international community around the world, particularly among West Asian countries. Recently, Iran has been extremely affected by the serious impacts of this destructive phenomenon, especially in its agricultural sector. Management of dust phenomenon increasingly calls for initiatives to understand the perceptions of farmers regarding this phenomenon. Farmers' views about dust phenomenon can affect their attitude and their mitigating behavior. This can also make a valuable frame for decision and policy-makers to develop appropriate strategies for mitigating dust phenomenon impacts on the agricultural sector. In line with this, a Q methodology study was undertaken to identify the perception of farmers toward dust phenomenon, in Khuzestan province, Iran. Sixty participants completed the Q sort procedure. Data analysis revealed three types of perceptions toward dust phenomenon: health adherents who seek support, government blamers who seek support, and planning adherents who seek information. Awareness of these perspectives is expected to promote the exchange of thought and knowledge among policy and decision-makers, and to support the development of a shared vision on dust phenomenon management

Is there any correlation between duration of vomiting before pyloromyotomy and eradication of symptoms after pyloromyotomy in hypertrophic pyloric stenosis?

Introduction: Hypertrophic pyloric stenosis (HPS) is among common GI disorders in young infants, with an incidence of 1-2:1000 live births in the world. In this study, we wanted to investigate the correlation between duration of symptoms before surgery and eradication of symptoms after pyloromyotomy in HPS.Materials and methods: One hundred and twenty five (102 boys and 23 girls) patients with suspected infantile HPS were treated surgically by Ramstedt pyloromyotomy between 2004 and 2014 at pediatric surgery ward of Tabriz Children’s Hospital, Iran. The demographic features, clinical findings, diagnostic work-up and postoperative specifications of the patients were studied retrospectively.Results: We studied 125 patients with HPS. Male to female ratio was 4:1. The patients were 16 to 90 days of old and the mean age was 39±1.42 days. The range of pyloric canal length was 7.60 to 29.00 mm and the mean length was 19.54±3.42 mm. Pyloric muscle diameter was 2.70 to 9.00 mm and the mean diameter was 4.86±1.14 mm. Seventy two percent of patients had episodes of vomiting after operation. Mean time of persistence of vomiting after pyloromyotomy was 15.73±0.15 hours. Mean discharge time was 55.22±0.08 hours. Radiologic findings did not show any significant correlation with persistence of vomiting or discharge time. Conclusion: The present study revealed that duration of vomiting before surgery and continuing symptoms could not predict postoperative symptom eradication after pyloromyotomy in HPS

The Impact of Livelihood Assets on the Food Security of Farmers in Southern Iran during the COVID-19 Pandemic

The impact of COVID-19 on farmers’ livelihoods and food security is a key concern in rural communities. This study investigates the impacts of the livelihood assets on the food security of rural households during the COVID-19 pandemic and determines those factors related to food security. The population of this study includes rural households in Dashtestan county, Bushehr province, in southern Iran. Based on the Krejcie and Morgan sampling table, 293 households were selected using the convenience sampling method. To measure food security, the American standard index and ordinal regression are used to analyze the factors. The results of the food security situation show highly precarious and food insecure situations among the studied rural households. The regression analysis shows that the most important assets affecting the food security of rural households under COVID-19 are financial, psychological, physical, and human assets, respectively. The results can help rural development planners and policymakers to improve both livelihoods and food security in rural communities, not just during the COVID-19 pandemic, but also in its aftermath.Open Access Fund of the Leibniz AssociationPeer Reviewe

SYNTHESIS AND CHARACTERIZATION OF BIOACTIVE GLASS/FORSTERITE NANOCOMPOSITES FOR BONE AND DENTAL IMPLANTS

In this research, bioactive glass (BG) of the type CaO–P2O5–SiO2 and nanocrystalline forsterite (NF) bioceramic were successfully synthesized via sol–gel processing method. Heat-treatment process was done to obtain phase-pure nanopowders. After characterization of each sample, the nanocomposite samples were prepared by cold pressing method and sintered at 1000°C. The samples were fully characterized by X-ray powder diffraction (XRD), scanning electron microscope (SEM), energy dispersive spectroscopy (EDX), Fourier transform infrared spectroscopy (FTIR) analyses. The average nanocrystallite size was determined using the Debye-Scherrer’s formula 19.6 nm. The bioactivity was examined in vitro with respect to the ability of hydroxyapatite (HAp) layer to form on the surfaces as a result of contact with simulated body fluid (SBF). According to the obtained results, the prepared nanocomposite enhances the fracture toughness of the BG matrix without deteriorating its intrinsic properties as bioactivity

Integrated food-based multi-actor approach to combat malnutrition

Despite initial progress, overall development toward zero hunger is not promising. Combating all forms of malnutrition is a complex challenge that requires complex answers from the local to global scales. To support a common understanding and to develop a joint approach that adequately addresses these challenges, an expert panel discussion was organized during the “Nutrition for Growth Summit Tokyo” on (7–8) December 2021 entitled “Multi-sectoral systems approach to holistically tackle malnutrition” upon which this article is based. We highpoint the requirement for actual access to ideas that move beyond the abstract and mostly figurative acknowledgment of the importance of bringing all actors together to combat malnutrition. Four entry points for a food-based multi-sectoral system approach to holistically tackle the burden of malnutrition were agreed upon. These entry points are not discrete, single entities but rather require integrated approaches. While we argue for an integrated approach building on all four interlinked components, it is important to note that the degree of each component's integration is context-dependent and that the examples presented as possible implementation strategies do not apply to all countries alike.Peer Reviewe

The global burden of cancer attributable to risk factors, 2010-19 : a systematic analysis for the Global Burden of Disease Study 2019

Background Understanding the magnitude of cancer burden attributable to potentially modifiable risk factors is crucial for development of effective prevention and mitigation strategies. We analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 to inform cancer control planning efforts globally. Methods The GBD 2019 comparative risk assessment framework was used to estimate cancer burden attributable to behavioural, environmental and occupational, and metabolic risk factors. A total of 82 risk-outcome pairs were included on the basis of the World Cancer Research Fund criteria. Estimated cancer deaths and disability-adjusted life-years (DALYs) in 2019 and change in these measures between 2010 and 2019 are presented. Findings Globally, in 2019, the risk factors included in this analysis accounted for 4.45 million (95% uncertainty interval 4.01-4.94) deaths and 105 million (95.0-116) DALYs for both sexes combined, representing 44.4% (41.3-48.4) of all cancer deaths and 42.0% (39.1-45.6) of all DALYs. There were 2.88 million (2.60-3.18) risk-attributable cancer deaths in males (50.6% [47.8-54.1] of all male cancer deaths) and 1.58 million (1.36-1.84) risk-attributable cancer deaths in females (36.3% [32.5-41.3] of all female cancer deaths). The leading risk factors at the most detailed level globally for risk-attributable cancer deaths and DALYs in 2019 for both sexes combined were smoking, followed by alcohol use and high BMI. Risk-attributable cancer burden varied by world region and Socio-demographic Index (SDI), with smoking, unsafe sex, and alcohol use being the three leading risk factors for risk-attributable cancer DALYs in low SDI locations in 2019, whereas DALYs in high SDI locations mirrored the top three global risk factor rankings. From 2010 to 2019, global risk-attributable cancer deaths increased by 20.4% (12.6-28.4) and DALYs by 16.8% (8.8-25.0), with the greatest percentage increase in metabolic risks (34.7% [27.9-42.8] and 33.3% [25.8-42.0]). Interpretation The leading risk factors contributing to global cancer burden in 2019 were behavioural, whereas metabolic risk factors saw the largest increases between 2010 and 2019. Reducing exposure to these modifiable risk factors would decrease cancer mortality and DALY rates worldwide, and policies should be tailored appropriately to local cancer risk factor burden.

Investigating the factors that affect pistachio growers’ intention regarding prevention of aflatoxin based on the health belief model in the Sirjan rural area

Pistachio is a valuable export product, but its export is faced with serious challenges due to aflatoxin. Given the importance of growers’ role in the prevention of aflatoxin in pistachio, the aim of this article is investigating pistachio growers’ intention regarding prevention of aflatoxin through the health belief model. The research population consists of 330 of pistachio growers in the Sirjan city in the Kerman province. Amongst the 330 samples, 120 of them were selected through simple random sampling. A questionnaire was the research tool and its validity of the questionnaire was approved by a panel of experts. Its reliability was confirmed by Cronbach alpha reliability coefficients (0.7 to 0.9). Also, the results of regression analysis revealed that the variables showing guide to action were the main predictor of growers’ intention. In addition to self-efficacy and perceived barriers, this variable can predict nearly 36% of the variance of pistachio growers’ intention regarding the prevention of aflatoxin. The results could be used for policy making and planning in relation to strategies to prevent the production of aflatoxin in pistachios
