Acute care nurses’ attitudes toward nursing students with disabilities: A focused ethnography

Discrimination towards individuals with disabilities is problematic within nursing. There have been calls to increase diversity in nursing and this includes embracing nurses with disabilities. Increasing diversity in nursing requires increasing diversity among nursing students; in this way, nurse educators are gatekeepers to the profession. Clinical education is a crucial element of nursing education, yet there have been very few studies related to the clinical education of nursing students with disabilities. There have been no studies of attitudes of acute care nurse preceptors toward students with disabilities in the United States. This gap is important as the majority of clinical experiences occur in the acute care environment. Utilizing a focused ethnography, semi-structured interviews were conducted with 20 acute care nurses with at least two years’ experience precepting students. While positive feelings about nursing students with disabilities were shared, thoughts and behavioral intentions remained negative. Six themes emerged: safety, barriers, otherness, communicating to meet needs, disclosure, and student versus colleague. Attitudinal barriers are the primary barriers faced by individuals with disabilities in becoming and practicing as nurses. Nurses in practice and education must embrace more inclusive attitudes towards individuals with disabilities.

Silver Diamine Fluoride Protocol for Reducing Preventable Dental Hospitalisations in Victorian Children

IntroductionThis study was designed to assess whether a dental caries management protocol combining a single application of 38% silver diamine fluoride (SDF) with comprehensive oral health education will successfully divert high-risk children from dental treatment under dental general anaesthesia (DGA), arrest active caries in primary teeth, and improve parent-reported child oral health–related quality of life (OHRQoL).MethodsChildren aged 2 to 10 years, who attended two public dental agencies in Victoria, Australia, and were unable to tolerate restorative treatments in the clinic setting, elected to participate in either a 38% SDF intervention protocol or, alternatively, referral for DGA. Follow-up examinations were completed at 6 months to assess caries progression, decayed missing filled tooth index, PUFA index (pulpal involvement, ulceration, fistula, abscess), DGA referral rates, and OHRQoL (Early Childhood Oral Health Impact Scale [ECOHIS]).ResultsOf the total sample, 89.5% of children (n = 102) [mean (SD) age, 4.1 (1.0) years] with 401 active carious lesions elected to participate in the 38% SDF protocol; 10.5% (n = 12) of parents opted for referral for treatment under DGA. The proportion of active caries subsequently arrested at follow-up (number of arrested lesions/number of lesions treated) was 0.78 (95% CI, 0.69 to 0.87). There was an 88% reduction in referrals for DGA in eligible children over the 6-month period. The 38% SDF intervention group showed a significant improvement in ECOHIS scores at follow-up (P < .001).DiscussionAdoption of the 38% SDF intervention protocol resulted in a significant reduction in the rate of preventable dental hospitalisations. Most parents opted against referral for DGA. Parent-reported OHRQoL for children improved significantly.     

Caffeic Acid–coated Nanolayer on Mineral Trioxide Aggregate Potentiates the Host Immune Responses,Angiogenesis, and Odontogenesis

IntroductionThe aim of this study was to investigate whether mineral trioxide aggregate (MTA) can be modified with caffeic acid (CA) to form caffeic acid/mineral trioxide aggregate (CAMTA) cement and to evaluate its physicochemical and biological properties as well as its capability in immune suppression and angiogenesis.MethodsMTA was immersed in trishydroxymethyl aminomethane buffer with CA to allow coating onto MTA powders. X-ray diffractometry and tensile stress-strain tests were conducted to assess for physical characteristics of CAMTA and to evaluate for successful modification of MTA. Then, the CAMTA cement was immersed in simulated body fluid to evaluate its hydroxyapatite formation capabilities and Si release profiles. In addition, RAW 264.7 cells and human dental pulp stem cells were used to evaluate CAMTA’s immunosuppressive capabilities and cell responses, respectively. hDPSCs were also used to assess CAMTA’s angiogenic capabilities.ResultsThe X-ray diffractometry results showed that CA can be successfully coated onto MTA without disrupting or losing MTA’s original structural properties, thus allowing us to retain the initial advantages of MTA. CAMTA was shown to have higher mechanical properties compared with MTA and had rougher pitted surfaces, which were hypothesized to lead to enhanced adhesion, proliferation, and secretion of angiogenic- and odontogenic-related proteins. In addition, it was found that CAMTA was able to enhance hydroxyapatite formation and immunosuppressive capabilities compared with MTA.ConclusionsCAMTA cements were found to have improved physicochemical and biological characteristics compared with their counterpart. In addition, CAMTA cements had enhanced odontogenic, angiogenic, and immunosuppressive properties compared with MTA. All of the results of this study proved that CAMTA cements could be a biomaterial for future clinical applications and tissue engineering use.     

健康干预在肥胖中学生中所起的效果评价

目的：探讨健康干预应用于肥胖中学生的效果。方法：抽取张掖市第一中学肥胖中学生180例，随机分为观察组与对照组，观察组实施健康干预，对照组仅予以常规健康教育，比较两组肥胖改善情况。结果：观察组干预效果显著优于对照组（P＜0．05）；干预后观察组的 BMI、腰围、胸围及皮脂厚度均较对照组显著降低（P＜0．05）。结论：在肥胖中学生中实施健康干预有利于促进学生身体形态生长水平的改善，控制和降低学生 BMI和肥胖增长速度。
