Does selective migration bias the health impact assessment of urban regeneration programmes in cross-sectional studies? Findings from a Dutch case study

We examined if the assessment of the health impact of a national Dutch regeneration programme depends on using either a repeated cross-sectional or longitudinal study design. This is important as only the latter design can incorporate migration patterns. For both designs, we compared trends in medication use between target and control districts. We found differences in medication use trends to be modest under the longitudinal design, and not demonstrable under the repeated cross-sectional design. The observed differences were hardly influenced by migration patterns. We conclude that in the Netherlands migration patterns had little effect on the health impact assessment of this national urban regeneration programme, so either the cross-sectional or longitudinal evaluation study design will do.     

Efficacy of adjuvant ozone therapy in reducing postsurgical complications following impacted mandibular third-molar surgery: A systematic review and meta-analysis

BackgroundResults from several randomized controlled trials have shown a beneficial effect of ozone in reducing postsurgical complications after impacted mandibular third-molar surgery, but the literature is lacking a systematic review and meta-analysis.MethodsThe authors conducted this systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines after exclusion and inclusion criteria were applied and the following outcome parameters were evaluated: pain, swelling, trismus, quality of life, number of analgesics consumed, and adverse events. RevMan Cochrane Collaboration software, Version 5.3, was used to perform meta-analysis and the Grading of Recommendation Assessment, Development and Evaluation approach was used to rate the certainty of evidence.ResultsPatients who underwent adjuvant ozone application reported lower pain scores than patients in the control group at 24 hours after surgery (95% CI, –3.94 to –1.56) and at 7 days (95% CI, –1.67 to –0.78). Pooled analysis of all 4 included trials revealed a standardized mean difference (SMD) in swelling of –0.44 at 24 hours, 0.63 at 72 hours, and –0.87 at 7 days after surgery in the experimental group. Higher mean estimates in mouth opening were experienced by patients who received ozone at 24 hours (SMD, 2.74; 95% CI, –1.93 to 7.41; 4 studies, 133 patients), 72 hours (SMD, 2.77; 95% CI, –0.63 to 6.17; 4 studies, 133 patients), and 7 days after surgery (SMD, 1.42 SMD; 95% CI, –1.34 to 4.18; 4 studies, 133 patients).Practical ImplicationsEvidence suggests that adjuvant ozone application can offer some benefit for reducing pain, improving quality of life, and decreasing mean intake of analgesics after impacted mandibular third-molar surgery, but it is not effective in reducing facial swelling and trismus, which paves the way for future research.     

Performance of lipid fingerprint-based MALDI-ToF for the diagnosis of mycobacterial infections

ObjectivesBacterial diagnosis of mycobacteria is often challenging because of the variability of the sensitivity and specificity of the assay used, and it can be expensive to perform accurately. Although matrix-assisted laser desorption/ionization mass spectrometry (MALDI MS) has become the workhorse of clinical laboratories, the current MALDI methodology (which is based on cytosolic protein profiling) for mycobacteria is still challenging due to the number of steps involved (up to seven) and potential biosafety concerns. Knowing that mycobacteria produce surface-exposed species-specific lipids, we here hypothesized that the detection of those molecules could offer a rapid, reproducible and robust method for mycobacterial identification.MethodsWe evaluated the performance of an alternative methodology based on characterized species-specific lipid profiling of intact bacteria, without any sample preparation, by MALDI MS; it uses MALDI-time-of-flight (ToF) MS combined with a specific matrix (super-2,5-dihydroxybenzoic acid solubilized in an apolar solvent system) to analyse lipids of intact heat-inactivated mycobacteria. Cultured mycobacteria are heat-inactivated and loaded directly onto the MALDI target followed by addition of the matrix. Acquisition of the data is done in both positive and negative ion modes. Blinded studies were performed using 273 mycobacterial strains comprising both the Mycobacterium tuberculosis (Mtb) complex and non-tuberculous mycobacteria (NTMs) subcultured in Middlebrook 7H9 media supplemented with 10% OADC (oleic acid/dextrose/catalase) growth supplement and incubated for up to 2 weeks at 37°C.ResultsThe method we have developed is fast (<10 mins) and highly sensitive (<1000 bacteria required); 96.7% of the Mtb complex strains (204/211) were correctly assigned as MTB complex and 91.7% (22/24) NTM species were correctly assigned based only on intact bacteria species-specific lipid profiling by MALDI-ToF MS.ConclusionsIntact bacterial lipid profiling provides a biosafe and unique route for rapid and accurate mycobacterial identification.     

Development of the Simulation-Positive Learning Evaluation (SIM-PLE) rubric for use in medical-surgical nursing high fidelity simulations

Clinical nurse educators in a BSN program developed the SIM-PLE (Simulation-Positive Learning Evaluation) rubric to evaluate student performance in simulation. A pilot study was conducted over two semesters with junior level medical-surgical classes made up of approximately 110–130 students each semester, and the tool was revised and re-evaluated. Inter-rater reliability testing utilized 69 SIM-PLE rubric student evaluations (N = 69). Inter-rater reliability was assessed with comparison of lead faculty with three other instructors utilizing two raters for each simulation experience. The intraclass correlation coefficient (ICC) suggested high inter-rater reliability. The t-test difference was not significant. One-way analysis of variance (ANOVA) showed a significant difference in the Collaboration subcategory score. Univariate ANOVA indicated both raters scored consistently with each other overall and that they both scored JR1 differently than JR2. The pilot study and testing of interrater reliability of the rubric revealed positive findings. The role of the rubric in providing formative feedback during debrief sessions empowered students to analyze their own performance and/or experience to self-correct or improve their future practice based on these experiences.     

The effect of a situation model nursing education action program on gender-bias awareness and gender-friendliness barriers in novice nursing students

AimThis study presents a workshop on the Situation Model Nursing Education Action program, examines how to promote gender awareness and decrease barriers related to differences in gender friendliness through the implementation of this program and tracks the trends of the relevant variables.DesignPre- and post-observations and a cohort study were conducted.MethodsA total of 58 nursing students (42 females and 16 males) were included. Nursing students were offered a gender-care intervention as two 90-minute workshops and surveys that measure gender awareness and gender friendliness were administered.ResultsThe results concerned gender-bias awareness and gender-friendliness barriers scores across the four weeks of the program intervention, with the generalized estimated difference score compared with the Week 1 baseline. Mean student scores showed that gender-bias awareness was significantly decreased at Week 2 (p < .001) and Week 4 (p < .001) and that mean gender-friendliness barrier scores significantly declined at Week 4 (p < .001).ConclusionsThe findings indicate that a faculty professional learning community workshop that facilitates intentional behavioral change can help faculty to become aware of gender bias, which can improve students’ gender awareness through clinical case discussion and lead to a decline in barriers to students’ gender friendliness.

伤口摄入超铀核素的内照射剂量估算

目的 比较NCRP伤口生物动力学模型和ICRP 78号报告推荐的注入模式下伤口摄入超铀核素所致内照射剂量的差异,了解器官剂量的分布特性。方法 以²⁴¹Am（M类,颗粒态）为例计算了上述两种不同模型模式下工作人员伤口摄入单位活度后所致人体各组织器官当量剂量和待积有效剂量,及其在部分器官（肝、骨等）和部分生物样品（尿、粪等）中的滞留/排泄分数曲线。结果 工作人员经由伤口摄入单位活度²⁴¹Am所致待积有效剂量的两种模型计算结果相差约为18.5%;器官当量剂量由高到低依次为骨表面,肝和红骨髓;伤口摄入单位活度²⁴¹Am后全身滞留分数较高,不易排出,在骨和肝中的滞留分数随时间推移而显著升高,而在尿、粪中的排泄分数则较低且变化较小。结论 利用现有的两种模型估算超铀核素伤口污染所致的内照射剂量尚有较大的差异,值得继续深入开展研究。
