Ecological sanitation, organic animal farm, and cogeneration: Closing the loop in achieving sustainable development—A concept study with on-site biogas fueled trigeneration retrofit in a 900-bed university hospital

ObjectiveWith the growing prevalence of overweight and obesity, medical students should be prepared to engage in weight management and obesity-related communications in order to prevent patients from having stigmatising experiences. In addition, medical students should have training to reduce anti-fat prejudices.DesignCross-sectional proof of concept study.SettingUniversity Hospital Tuebingen, Germany.Participants246 participants (207 second-year medical students, 13 standardised patients (SPs) and 22 teachers) took part in the study.Primary and secondary outcome measuresThe primary outcome was the assessment of degree of reality of the encounter with the SP wearing an obesity simulation suit (OSS). The secondary outcome was the evaluation of students’ awareness and prejudice against patients with obesity in a simulated role play. Additionally, a description of the advantages and disadvantages when using such a teaching tool is delivered.ResultsThe OSS contributed to a realistic perception of the patient group depicted in a role play according to students, teachers and SPs. OSS body mass index estimation by students, teachers and SPs correctly was over 30 kg/m2—thus in the range of obesity. In a selected subscale of the Anti-Fat Attitudes Test, students showed significantly stronger anti-fat stigmatisation compared with teachers and SPs.ConclusionsAn OSS worn by an SP is a valuable teaching tool to raise awareness about patients with obesity. It gives a realistic picture of the encounter. Stigmatisation was low in general but was especially present in the students. Further research should include intervention studies to address this issue.

Heterogenous catalytic ozonation of 2-chlorophenol (2-CP) in the presence of γ-alumina as a solid catalyst has been investigated in this research. It showed that the rate for degradation of TOC could increase from 21% to 43%. The pseudo-first reaction constants of 2-CP could increase from 0.8688 min-1 to 0.1270, increasing by approximately 40%. At the same time, the consumption of ozone was only half that of ozone alone. This research also explored the effects of the catalyst dosage, pH values and removal kinetics of 2-CP. In addition, three consecutive running with the same catalyst revealed insignificant reduction of the activity. Furthermore, the elimination of toxicity was evaluated by Microtox® analysis. The detoxification was more stable and with good results.

Sanitation Systems

Rapid population growth and urbanization are exerting excessive pressure on soil and water resources. To address these problems this paper proposes a cheap and sustainable alternative sanitation system, which accelerates nutrient recycling (“closing the loop”): ecological sanitation (ecosan) is a potential alternative to conventional sanitation systems that replenishes the organic matter and nutrients of the soil that are taken off as the crop harvest. A comparison is made of the environmental and the operation and maintenance costs between a modern wastewater treatment plant and on-site sanitation. An elevated double box urine diverting toilet (“ecotoilet”) is proposed and its advantages and disadvantages over a system with a centrally controlled modern WWTP are discussed. Bagmati Area Sewerage Project in Kathmandu is taken as an example of modern WWTP and ecosan being practiced in a village in Nepal is taken as an example of ecotoilet for the comparison.

Morphological Patterns

Recently, the functional aspect as well as morphological aspect of the reserve cells in the cervix uteri drew much attention in view of the carcinogenesis in squamocolumunar junction. In this communication, the authors elucidate the ultrastructural features of the reserve cells in patients of various age groups visiting our university hospital and affiliated hospital.From conventional light microscopic point of view, the reserve cells tend to be pronounced in various pathological conditions, such as the persisting inflammation, proliferative disorders and irritation of hormones. The morphological patterns of the reserve cells from various stage and degree of irritation were observed.
