Mixing ratios of trace gases in the austral polar atmosphere during August and September of 1987

Mixing ratios are presented for a number of long-lived trace gases in the austral polar atmosphere during August and September of 1987. The recent discovery of a 12-year trend of increasing depletion of ozone over the Antarctic Continent in the spring of each year led to numerous theoretical interpretations and several scientific expeditions to the region. The results herein were obtained as part of a major effort involving penetration of the region of ozone depletion by NASA's multi-instrumented aircraft. One of the 14 instruments on the high-altitude ER-2 aircraft collected pressurized air samples between latitudes of 53 degrees and 72 degrees south at pressure altitudes up to 21 km in a series of 12 flights from Punta Arenas, Chile, over the Palmer Peninsula. The sampling system, located in the nose section of ER-2, has an inlet tube in the free airstream, a metal-bellows air pump, and 14 specially treated 1.6 l stainless-steel canisters for containing the pressurized air at 350 kPa. A typical flight profile consisted of a southbound path on the 428 K potential temperature surface, a descent to a pressure altitude of 13.7 km, a climb to the 460 K surface, and return on this surface. Mixing ratios for the trace gases were obtained from gas chromatographic analyses of the pressurized air samples. Of the species measured, the mixing ratios for CH4, CO, N2O, CF2 Cl2, CFCl3, CH3, CCl3, CCl4, and C2F3Cl3 are reported here

Caring for cognitively impaired older patients in the general hospital: A qualitative analysis of similarities and differences between a specialist Medical and Mental Health Unit and standard care wards

Background: Around half of people aged over 70 admitted as an emergency to general hospital have dementia, delirium or both. Dissatisfaction is often expressed about the quality of hospital care. A medical and mental health unit was developed to provide best practice care to cognitively impaired older patients. The Unit was evaluated by randomised controlled trial compared to standard care wards. Part of this evaluation involved structured non-participant observations of a random sub-sample of participants and the recording of field notes. Objectives: The aim of this paper is to compare and contrast the behaviours of staff and patients on the Medical and Mental Health Unit and standard care wards and to provide a narrative account that helps to explain the link between structure, process and reported outcomes. Design: Field notes were analysed using the constant comparison method. Setting: A large hospital within the East Midlands region of the United Kingdom. Participants: Patient participants were aged over 65, and identified by Admissions Unit physicians as being ‘confused’. Most patients had delirium or dementia. Results: Sixty observations (360 hours) were made between March and December 2011. Cognitively impaired older patients had high physical and psychological needs, and were cared for in environments which were crowded, noisy and lacked privacy. Staff mostly prioritised physical over psychological needs. Person-centred care on the Medical and Mental Health Unit was mostly delivered during activity sessions or meal times by activities coordinators. Patients on this unit were able to walk around more freely than on other wards. Mental health needs were addressed more often on the Medical and Mental Health Unit than on standard care wards but most staff time was still taken up delivering physical care. More patients called out repetitively on the Unit and staff were not always able to meet the high needs of these patients. Conclusion: Care provided on the Medical and Mental Health Unit was distinctly different from standard care wards. Improvements were worthwhile, but care remained challenging and consistent good practice was difficult to maintain. Disruptive vocalisation may have been provoked by concentrating cognitively impaired patients on one ward

Enrollment of adolescents and young adults onto SWOG cancer research network clinical trials: A comparative analysis by treatment site and era.

BackgroundFew adolescents and young adults (AYAs, 15-39 years old) enroll onto cancer clinical trials, which hinders research otherwise having the potential to improve outcomes in this unique population. Prior studies have reported that AYAs are more likely to receive cancer care in community settings. The National Cancer Institute (NCI) has led efforts to increase trial enrollment through its network of NCI-designated cancer centers (NCICC) combined with community outreach through its Community Clinical Oncology Program (CCOP; replaced by the NCI Community Oncology Research Program in 2014).MethodsUsing AYA proportional enrollment (the proportion of total enrollments who were AYAs) as the primary outcome, we examined enrollment of AYAs onto SWOG therapeutic trials at NCICC, CCOP, and non-NCICC/non-CCOP sites from 2004 to 2013 by type of site, study period (2004-08 vs 2009-13), and patient demographics.ResultsOverall, AYA proportional enrollment was 10.1%. AYA proportional enrollment decreased between 2004-2008 and 2009-2013 (13.1% vs 8.5%, P < .001), and was higher at NCICCs than at CCOPs and non-NCICC/non-CCOPs (14.1% vs 8.3% and 9.2%, respectively; P < .001). AYA proportional enrollment declined significantly at all three site types. Proportional enrollment of AYAs who were Black or Hispanic was significantly higher at NCICCs compared with CCOPs or non-NCICC/non-CCOPs (11.5% vs 8.8, P = .048 and 11.5% vs 8.6%, P = .03, respectively).ConclusionNot only did community sites enroll a lower proportion of AYAs onto cancer clinical trials, but AYA enrollment decreased in all study settings. Initiatives aimed at increasing AYA enrollment, particularly in the community setting with attention to minority status, are needed
