The loss of RGCs is characteristic in several conditions such as glaucoma and trau- matic optic neuropathy and leads to visual loss and blindness.

All injurers had a direct assess to take medical care,and were immediately rescued and rapidly evacuated by air to Xining and Golmud at lower altitudes and admitted to advanced hospitals. Almost all of the injurers have been completely recovered. Yushu Earthquake was one of the highest earthquakes in the world,with a high incidence of acute altitude illness,which was observed in about 80 % of the lowland rescuers at an altitude of 4 000 m."Rescue the rescuers"became the major task of Qinghai-Tibetan rescue teams,all the severe patients were rapidly descended to Xining and treated promptly and effectively. The outcome was excellent,all patients survived. After the earthquake,it is a long and arduous task to reconstruct what has been destroyed. Medical teams continue to work in the Yushu Earthquake area because about 30 000 workers and carders are now here for rebuilding the earthquake center. Thus the prevention and treatment of altitude illness are still critical tasks for medical teams. Although all the fights are successful,there are more experiences and lessons we have learned from the medical mountain rescue during the earthquake and the reconstruction,and reports here are to sum up our experiences from the medical mountain rescue operation in Yushu Earthquake and draw the lessons that we should learn. With the increasing of earthquake probability occurring in the Qinghai-Tibetan Plateau,we also should prepare against earthquake disasters and for further rescue training in the high mountains.展开更多

Compared to other countries on a similar level of economic development Denmark has an extremely important agriculture and agribusiness sector. Danish agri and food cooperatives seem to have been successful in obtaining international competitiveness. The transformation and the structural development of the cooperative sector have more or less been completed. The development of the industrial structure among Danish agricultural cooperatives has been very rapid during the latest decades. Through mergers and acquisitions the number of firms has fallen dramatically, and the result has been increasing concentration ratios in almost all groups of the food industry. Structural development, concentration and globalization in recent decades have resulted in agri and food companies now being among the largest in Europe. To a large extent, agriculture all over the world faces similar problems and challenges. For this reason, it is essential that know-how, experiences and lessons can be transferred and adopted by agriculture in other countries around the world. In many ways, the experience and the success behind Danish agriculture and agribusiness can be transferred to other countries. However, profound studies of specific needs and conditions are necessary.展开更多

The effect was acute in the practice disciplines such as medicine, medical laboratory science, and nursing. The purpose is to describe how an interdisciplinary team, led by nursing faculty, adapted to the changes driven by COVID-19 and the lessons that were learned for nursing and other disciplines in higher education. <strong>Method:</strong> The interdisciplinary group created a comprehensive list which captured the impact of COVID-19 on their academic disciplines. Similarities and differences between the disciplines regarding faculty experiences, teaching, and responding to student concerns were discovered. <strong>Results:</strong> Collective review resulted in the identification of four inclusive thematic categories and several sub-categories. These were: academic considerations (didactic, lab, clinical), perceptions (faculty, student), ethical considerations, and social determinants affecting the learning environment. Lessons Learned: This project utilized an innovative interdisciplinary approach to identify common COVID-19 effects on higher education. <strong>Conclusions:</strong> Nursing and other health-related disciplines should pursue interdisciplinary collaboration to address common academic issues that arise during the COVID.展开更多

Nigeria is among the three countries that account for half of the 4.3 million “missing” TB cases globally. One untreated TB case is able to infect about 10 - 20 people annually. Hence, it is pertinent that TB is controlled effectively through the use of active case finding strategies to find the missing TB cases. Objective: This article highlights the best practices and key lessons learnt during the implementation of the active house to house TB case finding strategy in Nigeria. Lessons Learnt and Recommendations: Strategic community engagement, massive awareness creation using mass media and local means of communication, mapping of locations where registered TB cases live, to inform home visits for contact tracing and strengthening of laboratory systems, are viable mechanisms to improve TB case finding. Conclusion: Active TB case finding interventions should be implemented in the context of a strengthened diagnostics system, strategic community engagement and media involvement.展开更多
