School of the Wild\u27s Impact on Students\u27 Attitudes Towards the Outdoors, Learning Science, and Sustainability

Current educational priorities are forcing students to stay inside to the detriment of students’ well-being. Research proves that outdoor education provides many positive benefits for students’ learning, health, and relationships. With this in mind, we set out to answer the question of how an outdoor education program in the Midwest affects student’s attitudes towards science, the outdoors, and sustainability. The School of the Wild is a week-long outdoor education program provided to every sixth-grade student in the Midwest school district. We created an instrument to discover participants’ changes in attitudes towards the outdoors, learning science, and sustainability. Students were given the pre-survey in January before they participated in the program, and the post-survey was administered anywhere from one to three weeks after their time at the School of the Wild. We then compared the pre- and post-survey results in terms of all students surveyed and in terms of their self-identified gender. Overall, the School of the Wild experience seemed to benefit boys more than girls. Boys had a more positive shift in attitudes. While girls began with more positive attitudes towards science and the outdoors, the School of the Wild experience did not seem to greatly impact their attitudes. Some limitations for this study include the fact that the results are not generalizable, we were not able to track individual responses, and that post-surveys should be sent to schools with the same amount of time after participation for the best comparison. Future research might explore the impact of the entire program, or subsections of the program, on different races, socioeconomic statuses, or ages. Given the benefits of outdoor education discovered in this study as well as others, it is imperative that we adjust our educational priorities to include outdoor education

Single horizontal Y-V vermilion plasty including orbicularis oris muscle repair for secondary correction of the whistling defect: a universal technique

Objectives: The present prospective study aimed at objectively evaluating the relevance of a single horizontal Y-V vermilion plasty including orbicularis oris muscle repair for secondary correction of whistling deformities in unilateral as well as bilateral cleft lip cases. Study Design: Ten patients were included in the study (mean age 20.2±6.2 years). The size of the whistling defects was determined on photographs before and 12 months after surgery. Additional surgical procedures like columella lengthening and rhinoplasty were documented. Results: Seven minor and 3 moderate whistling defects were corrected. In 7 patients additional procedures were carried out. The data of the 12 months follow-up showed that the whistling defect was significantly reduced in size (p<0005). In 7 out of 10 patients the result of surgery was rated "good" and in 3 patients "moderate". Conclusions: The present prospective study is the first one to show on an objective basis that the presented technique allows reducing whistling deformities significantly with good overall results in the majority of the cases. Moreover, the technique can be combined with other corrective procedures like columella lengthening without problems. As a consequence, it is a relevant and universal surgical technique for the correction of whistling defects

Adverse health effects associated with household air pollution: a systematic review, meta-analysis, and burden estimation study

Background: 3 billion people worldwide rely on polluting fuels and technologies for domestic cooking and heating. We estimate the global, regional, and national health burden associated with exposure to household air pollution. Methods: For the systematic review and meta-analysis, we systematically searched four databases for studies published from database inception to April 2, 2020, that evaluated the risk of adverse cardiorespiratory, paediatric, and maternal outcomes from exposure to household air pollution, compared with no exposure. We used a random-effects model to calculate disease-specific relative risk (RR) meta-estimates. Household air pollution exposure was defined as use of polluting fuels (coal, wood, charcoal, agricultural wastes, animal dung, or kerosene) for household cooking or heating. Temporal trends in mortality and disease burden associated with household air pollution, as measured by disability-adjusted life-years (DALYs), were estimated from 2000 to 2017 using exposure prevalence data from 183 of 193 UN member states. 95% CIs were estimated by propagating uncertainty from the RR meta-estimates, prevalence of household air pollution exposure, and disease-specific mortality and burden estimates using a simulation-based approach. This study is registered with PROSPERO, CRD42019125060. Findings: 476 studies (15·5 million participants) from 123 nations (99 [80%] of which were classified as low-income and middle-income) met the inclusion criteria. Household air pollution was positively associated with asthma (RR 1·23, 95% CI 1·11–1·36), acute respiratory infection in both adults (1·53, 1·22–1·93) and children (1·39, 1·29–1·49), chronic obstructive pulmonary disease (1·70, 1·47–1·97), lung cancer (1·69, 1·44–1·98), and tuberculosis (1·26, 1·08–1·48); cerebrovascular disease (1·09, 1·04–1·14) and ischaemic heart disease (1·10, 1·09–1·11); and low birthweight (1·36, 1·19–1·55) and stillbirth (1·22, 1·06–1·41); as well as with under-5 (1·25, 1·18–1·33), respiratory (1·19, 1·18–1·20), and cardiovascular (1·07, 1·04–1·11) mortality. Household air pollution was associated with 1·8 million (95% CI 1·1–2·7) deaths and 60·9 million (34·6–93·3) DALYs in 2017, with the burden overwhelmingly experienced in low-income and middle-income countries (LMICs; 60·8 million [34·6–92·9] DALYs) compared with high-income countries (0·09 million [0·01–0·40] DALYs). From 2000, mortality associated with household air pollution had reduced by 36% (95% CI 29–43) and disease burden by 30% (25–36), with the greatest reductions observed in higher-income nations. Interpretation: The burden of cardiorespiratory, paediatric, and maternal diseases associated with household air pollution has declined worldwide but remains high in the world’s poorest regions. Urgent integrated health and energy strategies are needed to reduce the adverse health impact of household air pollution, especially in LMICs. Funding: British Heart Foundation, Wellcome Trus
