Analysing factors determining the adoption of environmental management measures on the highlands of Ethiopia

A study was conducted on the highlands of Ethiopia to identify and analyse the factors determining the adoption of environmental management measures. In 1985, Ethiopia was classified into low –and high-potential areas based on the suitability of the natural environment for rain-fed agriculture. To address these objectives, case study areas were selected from low-potential and high-potential areas randomly. Data were collected through face-to-face interview and key informants, focus group discussion and field observation. In the low-potential areas, the physical environment ‒ particularly soil and forest environments have shown substantial recovery. Similarly, the water environment has improved. However, in the high-potential areas sampled, these resources are still being degraded. Clear understanding of the benefits of soil conservation structures by farmers, active involvement and technical support from the government and full and genuine participation of farmers in communal environmental resources management activities were found to be main factors in the adoption of environmental management measures.

Long-term effects of watershed management on surface runoff and sediment loss in the Ethiopian Highlands

Data on rainfall, runoff and sediment loss from different land use types have been collected by the Soil Conservation Research Programme in seven small catchments (73-673 hectares) throughout the Ethiopian Highlands since the early 1980s. Monitoring was carried out on a storm-to-storm basis for extended periods of 10-20 years, and the data are analysed here to assess long-term effects of changes. Soil and water conservation technologies were introduced in the early years in the catchments in view of their capacity to reduce runoff and sediment yield. Results indicate that rainfall did not substantially change over the observation periods. Land use changes and land degradation, however, altered runoff, as shown by the data from small test plots (30 m2), which were not altered by conservation measures during the monitoring periods. Sediment delivery from the catchments may have decreased due to soil and water conservation, while runoff rates did not change significantly. Extrapolation of the results in the highlands, however, showed that expansion of cultivated and grazing land induced by population growth may have increased the overall surface runoff. Watershed management in the catchments, finally, had beneficial effects on ecosystem services by reducing soil erosion, restoring soil fertility, enhancing agricultural production, and maintaining overall runoff to the benefit of lowland areas and neighbouring countries.

Recurrent giant cell tumor of long bones: analysis of surgical management

Treatment of giant cell tumor of bone (GCT) often is complicated by local recurrence. Intralesional curettage is the standard of care for primary GCTs. However, there is controversy whether intralesional curettage should be preferred over wide resection in recurrent GCTs.

Influence of temperature management on neurocognitive function in biological aortic valve replacement. A prospective randomized trial

Aim of this study was to elucidate if postoperative neurocognitive function after biological aortic valve replacement (AVR) can be influenced by temperature management during cardiopulmonary bypass (CPB).

Determinants of timely management of acute bacterial meningitis in the ED

PURPOSE: The purpose was to study the emergency management of patients with suspected meningitis to identify potential areas for improvement. METHODS: All patients who underwent cerebrospinal fluid puncture at the emergency department of the University Hospital of Bern from January 31, 2004, to October 30, 2008, were included. A total of 396 patients were included in the study. For each patient, we analyzed the sequence and timing for the following management steps: first contact with medical staff, administration of the first antibiotic dose, lumbar puncture (LP), head imaging, and blood cultures. The results were analyzed in relation to clinical characteristics and the referral diagnosis on admission. RESULTS: Of the 396 patient analyzed, 15 (3.7%) had a discharge diagnosis of bacterial meningitis, 119 (30%) had nonbacterial meningitis, and 262 (66.3%) had no evidence of meningitis. Suspicion of meningitis led to earlier antibiotic therapy than suspicion of an acute cerebral event or nonacute cerebral event (P < .0001). In patients with bacterial meningitis, the average time to antibiotics was 136 minutes, with a range of 0 to 340 minutes. Most patients (60.1%) had brain imaging studies performed before LP. On the other hand, half of the patients with a referral diagnosis of meningitis (50%) received antibiotics before performance of an LP. CONCLUSIONS: Few patients with suspected meningitis received antimicrobial therapy within the first 30 minutes after arrival, but most patients with pneumococcal meningitis and typical symptoms were treated early; patients with bacterial meningitis who received treatment late had complex medical histories or atypical presentations.

A 10-year longitudinal analysis of surgical management for acute ischemic colitis

Our objective was to review our 10-year experience of surgical resection for acute ischemic colitis (IC) and to assess the predictive value of previously reported risk-stratification methods.

Guidance for the preparation of neurological management guidelines by EFNS scientific task forces - revised recommendations 2012

This paper is meant to provide guidance to anyone wishing to write a neurological guideline for diagnosis or treatment, and is directed at the Scientist Panels and task forces of the European Federation of Neurological Societies (EFNS). It substitutes the previous guidance paper from 2004. It contains several new aspects: the guidance is now based on a change of the grading system for evidence and for the resulting recommendations, and has adopted The Grading of Recommendations, Assessment, Development and Evaluation system (GRADE). The process of grading the quality of evidence and strength of recommendations can now be improved and made more transparent. The task forces embarking on the development of a guideline must now make clearer and more transparent choices about outcomes considered most relevant when searching the literature and evaluating their findings. Thus, the outcomes chosen will be more critical, more patient-oriented and easier to translate into simple recommendations. This paper also provides updated practical recommendations for planning a guideline task force within the framework of the EFNS. Finally, this paper hopes to find the approval also by the relevant bodies of our future organization, the European Academy of Neurology.
