We derive averaging formulas for the Lefschetz coincidence numbers,the Nielsen coincidence numbers and the Reidemeister coincidence numbers of maps on infra-solvmanifolds modeled on a connected and simply connected solvable Lie group of type(R).As an application,we compare our formula for the Nielsen coincidence numbers with a result of Jezierski(1992)for pairs of maps on some infra-solvmanifolds of *** all the pairs of self-maps of a nonorientable infra-solvmanifold of Sol,we determine the sets of all the possible values of the Nielsen coincidence numbers and the Reidemeister coincidence numbers.

BACKGROUND Low vitamin D levels are associated with a more severe case of knee osteoarthritis(OA).However,there are few published reports concerning an association between vitamin D deficiency and functional status of individuals with OA and no reports about postural balance in this *** To analyze the relationship between vitamin D deficiency and severity,functional status,and balance in elderly patients with *** In this cross-sectional study,105 elderly patients with hip and knee OA were *** severity was assessed by the Kellgren-Lawrence *** functional status was assessed with the Lequesne *** balance was assessed using a force platform,and center-of-pressure parameters(velocity at anteroposterior and mediolateral axis)were used as the balance *** 25(OH)vitamin D levels were measured using a chemiluminescence *** Most of the patients(mean age:70.6±6.5 years)were female(n=78,74.3%).In the group with vitamin D deficiency,43 patients(56.6%)had severe OA,while 33 patients(43.4%)had mild or moderate OA(χ^(2) test,P=0.04).Patients with vitamin D deficiency showed a higher Lequesne index score(Mann-Whitney test,P=0.04),indicating a worse functional impairment when compared to individuals with normal vitamin D ***,patients with vitamin D deficiency had worse postural balance according to the Mann-Whitney test(P=0.03).CONCLUSION Vitamin D deficiency is associated with worse severity,functional status,and postural balance in patients with OA.

The Nursing Documentation Dilemma in Uganda: Neglected but Necessary. A Case Study at Mulago National Referral Hospital

Open Journal of Nursing 2015年第12期5卷 1063-1071页

In Uganda, nursing documentation still remains a challenge, in most of the government hospitals and some private hospitals, it remains at a manual (non-technology driven) level and omissions have been observed. Nurses continue to capture standard elements in their documentation. A mixed methods intervention study was conducted to determine knowledge and attitudes of nurses towards documentation, including an evaluation of nurses’ response to a designed nursing documentation form. Forty participants were selected through convenience sampling from six wards of a Ugandan health institution. The study intervention involved teaching nurses the importance of documentation and using of the trial documentation tool. Pre- and post-testing and open-ended questionnaires were used in data collection. The results from the close-ended questions were presented in the previous publication;the responses from the open-ended questions would then be presented. The open-ended questions regarding comments about the nursing documentation process and suggestions about the process of implementing the nursing documentation system in the ward units were considered. All participants were provided the opportunity to provide personal comments, reflections, or stories of their experiences with documentation in patient care. A thematic analysis approach was used during data analysis. The results showed that the participants had positive attitude towards documentation of patient care, but they had constraints limiting them to document, they reflected issues concerning the perceived pressure from the administrations and support to document. The study findings have implication that there is need for organizational support and to have multisite studies and extension of the documentation tool.
