However, high-heeled shoes can cause discomfort and injury and can change the body’s center of gravity when maintaining balance. This study developed an assessment system for predicting the maximal safe range for heel height by recording the plantar pressure of participants’ feet by using force-sensing resistor (FSR) sensors and conducting analyses using regression models. Specifically, 100 young healthy women stood on an adjustable platform while physicians estimated the maximal safe height of high-heeled shoes. The collected FSR data combined with and without personal features were analyzed using regression models. The experimental results showed that the regression model based on the pressure data for the right foot had better predictive power than that based on data for the left foot, regardless of the module. The model with two heights had higher predictive power than that with a single height. Furthermore...

Hemodialysis quality is crucial for the health care quality of patients requiring such treatment. Complications related to hemodialysis access may reduce hemodialysis quality. Content Outline: Vascular access is the main access method for administering hemodialysis to patients. Hemodialysis quality is crucial for the health care quality of patients requiring such treatment. Complications related to hemodialysis access may reduce hemodialysis quality. With a view to maintaining patients’ health care quality, this study analyzed data from the Taiwan Society of Nephrology: Kidney Dialysis, Transplantation (TSN KiDiT) registration system and investigated the steps involved in continuous quality improvement to understand the relationship between hemodialysis access types and health care quality and shed light on the various types of access through which patients currently receive hemodialysis. ...

The negative binomial distribution (NBD) contains two characteristics which are Poisson purchasing and gamma heterogeneity is shown as a robust method in product purchase frequency. An approach is to develop individual-level estimation b y MCMC Bayesian NBD model. Since the smart phone launch to publish, many companies start to design app to approach their customers. The app can work successfully only when they meet customers' requirements. An e mpirical exam is to estimate effects that influence the app download frequency for different catalog. Four different types of app results are compared. The proposed model can capture app download frequency successfully.

The aim of our study was to investigate the effect of BP in different time intervals within the first 24 hours after EVT on functional outcomes.MethodsData of patients who received EVT for acute ischemic stroke at two institutions were reviewed. After EVT, hourly BP data were collected and divided into four time intervals: 1–6 hours, 7–12 hours, 13–18 hours, and 19–24 hours. The mean, maximum, and standard deviation (SD) of BP were calculated and compared with the outcome of interest in patients with successful recanalization. The outcome of interest was functional independence, which was defined as a 3-month modified Rankin Scale score of ≤2.ResultsOf 224 patients with stroke who received EVT, 166 (74.1%) (mean age 70.2±13.1 years; 49.4% men) achieved successful recanalization and 82 (49.4%) exhibited functional independence.

The community data were generated to support user decision and featured instant game records and odds data synchronisation. Furthermore, the next development cycle were evaluated through a questionnaire. Design/methodology/approach – An extended prototype website development methodology was applied to develop the system. An online sample was collected to evaluate the function, interface, operation, and prediction designs. The χ2 test and variance analysis were used to determine the association between facets and basic demographics. Finally, the regression model was used to identify the potentially essential predictors that influence the measurement facets. Findings – The high frequency of Facebook users, sports lottery purchases, and sports game viewers prefer the ability to predict the results of future sports games as adv...

This study employed a two-stage model from 3-year echocardiographic data to ascertain whether the two-stage model predicts RFCA outcome more favorably than models using the baseline LAD. Methods Data were retrospectively collected from 263 consecutive patients with drug-refractory AF undergoing RFCA. Regular echocardiographic measurements of LAD were performed at baseline, 1, 3, 6, and 12 months and then every 6 months after RFCA. Sex, age, type of AF, number of RFCA, and AF status were recorded. We obtain the actual (predicted) 3-year LAD using a longitudinal linear mixed model (1st stage). Logistic regression models based on the baseline LAD (Model 1), actual (predicted) 3-year LAD (Model 2) (2nd stage), and observed 3-year LAD (Model 3) were constructed to predict RFCA outcome. The area under the ...

However, whether certain central nervous system-specific plasma biomarkers correlate with the outcomes is unknown. We evaluated the temporal changes and prognostic roles of the levels of these biomarkers in patients with AIS undergoing EVT. Methods We enrolled 60 patients who received EVT for AIS and 14 controls. The levels of plasma biomarkers, namely neurofilament light chain (NfL), glial fibrillary astrocytic protein (GFAP), tau, and ubiquitin C-terminal hydrolase L1 (UCHL1), were measured with an ultrasensitive single molecule array before, immediately after, and 24 h after EVT (T1, T2, and T3, respectively). The outcomes of interest were death or disability at 90 days (defined as a modified Rankin Scale score of 3–6) and types of hemorrhagic transformation (hemorrhagic infarction or parenchymal hemorrhage). Results Of t...

Descriptive. National Cancer Institute-designated comprehensive cancer center. 417 nurses employed at the cancer center were surveyed; 250 (60%) subjects responded. 59-item questionnaire. Nurses' attitudes toward clinical trials and perceptions of patient understanding of and influences on participation in clinical trials. 96% of nurses reported that participation in clinical trials is important to improving standards of care; only 56% believed that patients should be encouraged to participate in trials if they had cancer. In multiple regression analyses, older age and being a research nurse were significant predictors of positive attitudes toward clinical trials. Work setting also was a significant predictor of nurses' perceptions of patients' understanding of treatment. Overall, nurses reported that an ...

Patients and Methods: We evaluated a random retrospective cohort of 2,517 Medicare beneficiaries treated for newly diagnosed stage I or II breast cancer from 1992 through 1994. The outcome measures were quality-adjusted life-years (QALYs) and 5-year medical costs. Risk and propensity score adjustments were used in the analysis. Results: A breast conservation and radiation regimen has significantly higher costs than mastectomy in the first year after surgery; the adjusted 5-year costs are $14,054 (95% confidence interval, $9,791 to $18,312) greater than those of mastectomy. The adjusted incremental cost-effectiveness ratio comparing breast conservation and radiation to mastectomy was $219,594 per QALY for the comparison of the two strategies. If the p...

We evaluated posttreatment quality of life and satisfaction in a national population. Patients and Methods: Telephone surveys were conducted with a random cross-sectional sample of 1,812 Medicare beneficiaries 67 years of age and older who were 3, 4, and 5 years posttreatment for stage I and II breast cancer. Regression models were used to estimate the adjusted risk of decrements in physical and mental health functioning by treatment. In a subset of women (n = 732), additional data were used to examine arm problems, impact of cancer, and satisfaction, controlling for baseline health, perceptions of ageism and racism, demographic and clinical factors, region, and surgery year. Results: Use of axillary dissection was the only surgical treatment that affected outcomes, increasing the risk of arm problems four-fold (95% confidence interval, 1.56 to 10.51), controlling for other factors. Having arm proble...
