RESUMO
Worldwide, 40% population consumes wheat (Triticum aestivum L.) as a staple food that is low in zinc (Zn) content. Zn deficiency is a major micronutrient disorder in crop plants and humans worldwide, adversely impacting agricultural productivity, human health and socio-economic concern. Globally, the entire cycle of increasing the Zn concentration in wheat grains and its ultimate effect on grain yield, quality, human health & nutrition and socio-economic status of livelihood is less compared. So the present studies were planned to compare the worldwide studies for the alleviation of Zn malnutrition. Zn intake is affected by numerous factors from soil to crop, crop to food and food to humans. The post-harvest fortification, diversification in dietary habits, mineral supplementation and biofortification are various possible approaches to enhance the Zn concentration in food. The wheat grains Zn is influenced by the Zn application technique and time concerning crop developmental stages. The use of soil microorganisms mobilize unavailable Zn, and improve Zn assimilation, plant growth, yield and Zn content in wheat. Climate change can have an inverse impact on the efficiency of agronomic biofortification methods due to a reduction in grain-filling stages. Agronomic biofortification can improve Zn content, crop yield as well as quality and ultimately, have a positive impact on human nutrition, health and socioeconomic status of livelihood. Though bio-fortification research has progressed, some crucial areas are still needed to be addressed or improved to achieve the fundamental purpose of agronomic biofortification.
RESUMO
PURPOSE: The optimal treatment for adult mandibular condylar fractures (MCFs) has largely shifted in favor of open reduction and rigid internal fixation. However, a sizeable portion of these injuries are still being treated in a closed manner based on old literature, convenience, results deemed acceptable, and lesser associated morbidity. Most MCFs with multiple associated facial traumas are appropriately treated under general anesthesia (GA). However, some selected isolated MCFs or those with minimal associated mandibular or low midfacial fractures can be treated optimally with patients under local anesthesia following a protocol presented in this article, thus expediting and simplifying their management. The purpose of this study was to develop a safe, sound, effective protocol for routine surgical management of mandibular subcondylar fractures under local anesthesia. PATIENTS AND METHODS: We carried out a prospective clinical study to assess the feasibility of operating on MCFs with patients under local anesthesia. Seven patients with MCFs and other associated facial fractures underwent surgery after careful case selection following our proposed protocol. The outcome variables were 1) duration of the procedure, 2) intraoperative pain assessed by a visual analog scale, 3) fracture reduction assessed by measuring the preoperative and postoperative average fracture gap, 4) presence of malocclusion preoperatively and postoperatively, 5) deviation on mouth opening, and 6) maximal mouth opening. RESULTS: The mean duration of the procedure was 35.14 minutes, and the mean rating of intraoperative pain or discomfort was 0.57 as reported on the visual analog scale by the patients. Mean mouth opening improved from 17.1 to 40.5 mm, whereas deviation on opening improved from 4.4 to 0.28 mm. The average fracture gap was reduced from 6.32 to 0.97 mm. CONCLUSIONS: The presented protocol is a straightforward, efficient, safe, cost-effective tool for operating on MCFs, avoiding GA with its attendant risks and complications, that can be used routinely, as well as in patients for whom GA is deemed unsuitable.
