Prevalensi diabetes melitus yang semakin meningkat setiap tahunnya cenderung meningkatkan risiko komplikasi dan kematian akibat diabetes melitus itu sendiri. Tujuan penelitian ini adalah untuk mengetahui pengaruh edukasi perubahan gaya hidup sehat terhadap clinical outcome (parameter klinis) pada pasien di Rumah Diabetes Universitas Surabaya. Rancangan penelitian menggunakan one group pretest-posttest yang diikuti oleh 27 subjek diabetes melitus di Rumah Diabetes Universitas Surabaya. Seluruh subjek diberikan edukasi (intervensi) dengan perangkat piring sehat dengan durasi 4 minggu. Pengukuran clinical outcome dilakukan terhadap gula darah puasa, indeks massa tubuh (IMT), lingkar perut, dan tekanan darah. Uji statistika yang digunakan adalah Wilcoxon signed rank test dan paired t-test. Hasil penelitian menunjukkan bahwa edukasi perubahan gaya hidup sehat berpengaruh signifikan terhadap penurunan gula darah puasa (p<0,001), indeks massa tubuh (p=0,005), lingkar perut (p=0,005), tekanan darah sistolik (p=0,013), namun tidak signifikan terhadap tekanan darah diastolik (p=0,247). Dapat disimpulkan bahwa edukasi perubahan gaya hidup sehat berpengaruh terhadap gula darah puasa, indeks massa tubuh, lingkar perut, dan tekanan darah sistolik. Keterbatasan dalam penelitian ini adalah keikutsertaan penderita diabetes melitus yang sedikit serta tidak adanya kelompok kontrol sebagai pembanding.

AbstractThe evaluation of geoscience data is a far-reaching topic which cannot be systematically covered. The purpose of inferential statistics is to harness useful information from data for making decisions. This paper conducts in-depth statistical study for the Bursa-Wolf and Molodensky Badekas models of the three-dimensional transformation parameters. We also considered the combined and observation equations scenarios of these methods for the comparative study. Four key indicators are conducted to evaluate the performance of the two transformation models according to the residual results. These include root mean square error (RMSE), paired t-test, Wilcoxon signed-rank test and the Cohen’s d effect size measure. RMSE evaluation is based on the mean difference between model estimates and observed values. The correlations in the model results is investigated based on paired t-test. Wilcoxon signed-rank test assesses the statistical significance of the model’s paired differences. To estimate the effect size of the performance differences, Cohen’s d measures are computed. Further, the residuals of the estimated parameters are plotted according to their respective control points. The inference results of these tests generally show that Badekas transformation approach is more precise than Bursa-Wolf. Specifically, Badekas combined case is the most precise, followed by its observation case, then Bursa-Wolf combined and finally its observation case is the least performing model. The application of various data analysis and statistical verifications make the task of data interpretation and best model selection easier.

OBJECTIVE: To compare broth microdilution and E-test minimum inhibitory concentrations (MICs) of 4 fluoroquinolones against Streptococcus pneumoniae and to determine the effect of these in vitro MIC methods on the calculation of AUC0–24/MIC ratios. METHODS: Levofloxacin, gatifloxacin, moxifloxacin, and gemifloxacin MICs were determined by broth microdilution (incubated in air) and E-test (incubated in CO2) for 100 clinical isolates of S. pneumoniae. MIC50, MIC90, and geometric mean MIC were calculated. Steady-state serum concentration—time profiles were simulated for once-daily, oral dosing of levofloxacin 500 mg, gatifloxacin 400 mg, moxifloxacin 400 mg, and gemifloxacin 320 mg. After correcting for protein binding, AUC0–24 of unbound drug was calculated for each regimen, and AUC0–24/MIC ratios were calculated using MIC data from both in vitro methods. Differences in MICs between methods were determined for each agent using the paired t-test (after logarithmic transformation of MICs) and the Wilcoxon signed-rank test. Differences in AUC0–24/MIC ratios were also determined using the paired t-test and the Wilcoxon signed-rank test. The level of significance for all analyses was p < 0.05. RESULTS: Broth microdilution and E-test MICs were within ± 1 log2 dilution for 94%, 93%, 61%, and 35% of the isolates for levofloxacin, gatifloxacin, moxifloxacin, and gemifloxacin, respectively. Broth microdilution MICs were significantly lower than E-test MICs for all 4 agents (p < 0.001). However, a categorical change in susceptibility was seen for only 1 isolate with gatifloxacin and moxifloxacin (intermediate by broth microdilution, resistant by E-test). AUC0–24/MIC ratios were significantly higher for each regimen when MICs were determined by broth microdilution compared with E-test (p < 0.001). CONCLUSIONS: There is a significant difference in the activity of the newer fluoroquinolones against S. pneumoniae when MICs are determined by broth microdilution and E-test. When evaluating fluoroquinolone activity and pharmacodynamics against this organism, clinicians must be aware that MIC testing methodology may have a significant impact on the results.

Abstract Cephalometric norms are important to orthodontists in their diagnosis, treatment, and evaluation of orthodontic treatment outcomes. The purpose of the present study is to establish if orthodontists treat and finish their cases to the cephalometric means or norms. Pre- and post-cephalometric radiographs and dental casts of 35 orthodontically treated cases were analyzed. The Kappa test, Wilcoxon Signed-Rank test, Paired t- test, and Z-test were used for the statistical analysis of the data. The result revealed that orthodontists do not reach the cephalometric mean values post-treatment. However, sagittal maxillomandibular relationship and interlabial gap are the main areas of improvements. This leads to improvement of soft tissue esthetics by camouflaging the skeletal and dental relationship. Citation Al-Balkhi KM.

This quasi-experimental research examined the effects of the process/genre approach (PGA) with the integration of blogs in EFL university-level students’ writing classrooms. This was a mixed-method study in which the participants’ essays and adopted questionnaires contributed to accumulating quantitative data while the interviews and observations provided qualitative data. The study took place over ten weeks at a university in central Taiwan in which paper-pencil instruction was applied in the control group, while blog instruction was employed for the experimental group. The students’ essays were computed by applying a paired-sample t-test, and the questionnaires were analysed by applying a Wilcoxon signed-rank test to determine whether there were any statistically significant differences in terms of the students’ writing performance and perceptions toward the PGA and blog writing after comparing the results of the pre-test and the post-test. The qualitative data was analysed to provide in-depth evidence to support the quantitative results. After the data analysis was completed, the paired-sample t-test demonstrated that there were significant differences in terms of the students’ writing performance in both groups, which demonstrates how the PGA developed the EFL university students’ writing performance. Because the students had more interactive opportunities to be exposed to the language inputs, this approach facilitated their English writing performance. The Wilcoxon signed-rank test presented that the students revealed positive attitudes toward writing blogs and also positive affections toward blog writing because they had higher levels of satisfaction and lower levels of apprehension when blogging. Moreover, there was a significant difference in terms of the factor of “learning with peers” in the control group since the PGA provided more interactive and communicative opportunities. The students also indicated greater understanding about their writing samples in the experimental group, since they were allowed to refer to the instructional contents on the blogs anytime and anywhere.
