Guidance Systems

BACKGROUND Hospital information systems have been widely adopted across China, in recent years, significantly changing the way in which hospitals manage their processes and patient visits. Intelligent Guidance Systems for Patients (IGSP), which resemble humanoid characteristics using Artificial Intelligence (AI), assist patients in navigating hospital visits, obtaining medical guidance, consultation, and other medical services. Despite their widespread adoption in tertiary transfer hospitals in China, usability studies on such systems are scarce. To date, there is no practical or standardized measurement of system usability, leading to difficult inspection, maintenance and servicing processes. OBJECTIVE IGSP can improve user experiences pre, during and post hospital visits. This study aims to determine the usability deficiency of IGSP and understand how various factors influence users’ satisfaction during use. METHODS Employing the requirements set out in the ISO9214-11:2018 standard, two inspection methods were used with 3 experts and 360 recruited end-users. First, the Heuristic evaluation method was employed to detect usability problems and to demonstrate any violations of Nielsen’s 10 heuristic principles. Second, the System Usability Scale (SUS) was applied to evaluate participants’ satisfaction towards IGSP. Finally, analysis of variance tests and a multiple linear regression analysis was performed to establish correlations between user satisfaction and various characteristics. RESULTS A total of 78 problems violated the heuristic principles for 169 times. These problems were divided into five categories: voice interaction, in-hospital navigation, medical consultation, interactive interface design, and miscellaneous. The average SUS score for IGSP was 72.8 (SD 14.69), indicating a good usability level. User satisfaction scores differed among hospitals (F=3.513, P=.031), age of user (F=6.010, P=.000), and smartphone usage time (F=4.781, P=.000). The multiple linear regression model reflected participants’ education level (t=-2.41, p= .016) and gender (t=-2.080, p=.038), while medical industry (t=-2.074, p=0.039) had a negative effect on user satisfaction scores. Conversely, daily smartphone usage times (t= 2.470, p=.014) helped to increase user satisfaction scores. CONCLUSIONS This study demonstrates that IGSP can improve user experiences during interaction between patient and hospital. However, system usability deficiencies did exist; some of which must be addressed. Our findings are considered conducive to tertiary transfer hospitals in developing user-friendly IGSP for improving patient experiences. Tertiary hospitals should take full advantage of IGSP to help reduce waiting times and meet the various needs of patients pre, during and post hospital visit. User-centered conception should be integrated into the process of design and modification of IGSP.

Attitudinal Factors

Behavioral Finance is an evolving field that studies how psychological factors affect decision making under uncertainty. Herding behavior is one of the psychological factors that instigate investor to mimic the actions of other investors in the market rather than using his personal assessments. This study seeks to find the influence of certain attitudinal factors namely, decision conformity, hasty decision, mood, decision accuracy, and overconfidence, on the individual investor tendency to embrace herd behavior. Primary data for the study are collected using structured questionnaires from a sample of 194 investors who are trading at Islamabad and Lahore branches of Pakistan Stock Exchange. Multiple linear regression analysis is used to test the hypotheses of this study. Findings of this study provide evidence that attitudinal factors have a significant influence on investor’s tendency to take on herd behavior. It is concluded from the results of multiple linear regression that decision conformity, mood, and decision accuracy have a significant impact on individual investor tendency to adopt herd behavior. However, investor hasty decision and overconfidence is insignificant predictors of herd behavior.

AbstractMultiple studies found hamstring tendon (HT) autograft diameter to be a risk factor for anterior cruciate ligament (ACL) reconstruction failure. This study aimed to determine which preoperative measurements are associated with HT autograft diameter in ACL reconstruction by directly comparing patient characteristics and cross-sectional area (CSA) measurement of the semitendinosus and gracilis tendon on magnetic resonance imaging (MRI). Fifty-three patients with a primary ACL reconstruction with a four-stranded HT autograft were included in this study. Preoperatively we recorded length, weight, thigh circumference, gender, age, preinjury Tegner activity score, and CSA of the semitendinosus and gracilis tendon on MRI. Total CSA on MRI, weight, height, gender, and thigh circumference were all significantly correlated with HT autograft diameter (p < 0.05). A multiple linear regression model with CSA measurement of the HTs on MRI, weight, and height showed the most explained variance of HT autograft diameter (adjusted R 2 = 44%). A regression equation was derived for an estimation of the expected intraoperative HT autograft diameter: 1.2508 + 0.0400 × total CSA (mm2) + 0.0100 × weight (kg) + 0.0296 × length (cm). The Bland and Altman analysis indicated a 95% limit of agreement of ± 1.14 mm and an error correlation of r = 0.47. Smaller CSA of the semitendinosus and gracilis tendon on MRI, shorter stature, lower weight, smaller thigh circumference, and female gender are associated with a smaller four-stranded HT autograft diameter in ACL reconstruction. Multiple linear regression analysis indicated that the combination of MRI CSA measurement, weight, and height is the strongest predictor.

Wnt Proteins

Background: Carboxylesterase Notum is a negative regulator of Wnt signaling. Notum carboxylesterase is a carboxylic ester hydrolase enzyme that functions as a negative feedback regulator of Wnt proteins by depalmitoylation reaction. It is of great importance to understand the pathway of Wnt regulation because, conversely, misregulation of Wnt signaling is a telltale sign of cancer and other degenerative diseases. The Wnt inhibition is important in the control of colorectal cancer. Objective: In the present study, we carried out a QSAR analysis of a series of reported compounds with carboxylesterase Notum inhibitory activity using multiple regression analysis. A series of 83 compound datasets of pyrrole derivatives with carboxy Notum inhibitory values were taken from the reported literature. Methods: The study was performed by conducting multiple linear regression analysis followed by validation of the model. The multiple linear regression (MLR) models with the highest coefficients of correlation (R2) and explained variance in leave-one-out (Q2 LOO) prediction and leave-many-out (Q2 LMO) were selected for the whole dataset. The developed models were subjected to internal and external validation. The reliability of the predicted model was checked by plotting the Williams plot. The docking methodology was performed using Autodock 4 for the designed compounds to study the interaction between the ligand and the receptor. Results: The best model generated exhibited an r2 value of 0.7413, Q2LOO =0.6379, Q2LMO =0.6368. Novel compounds of phenyl pyrrolidine were designed based on generated QSAR equations. The carboxylesterase Notum inhibitory activity was predicted using the QSAR equations. The docking studies were carried out for designed compounds using Autodock against Carboxylesterase Notum esterase. Conclusion: From the results, the designed compounds were found to inhibit Notum Carboxylase. Thus, the study led to the development of a novel lead compound for Carboxylesterase Notum.

ABSTRACT Accurate estimation of chlorophyll-a (Chl-a) concentration in inland waters through remote-sensing techniques is complicated by local differences in the optical properties of water. In this study, we applied multiple linear regression (MLR), artificial neural network (ANN), nonparametric multiplicative regression (NPMR) and four models (Appel, Kahru, FAI and O14a) to estimate the Chl -a concentration from combinations of spectral bands from the MODIS sensor. The MLR, NPMR and ANN models were calibrated and validated using in-situ Chl -a measurements. The results showed that a simple and efficient model, developed and validated through multiple linear regression analysis, offered advantages (i.e., better performance and fewer input variables) in comparison with ANN, NPMR and four models (Appel, Kahru, FAI and O14a). In addition, we observed that in a large shallow subtropical lake, where the wind and hydrodynamics are essential factors in the spatial heterogeneity (Chl-a distribution), the MLR model adjusted using the specific point dataset, performed better than using the total dataset, which suggest that would not be appropriate to generalize a single model to estimate Chl-a in these large shallow lakes from total datasets. Our approach is a useful tool to estimate Chl -a concentration in meso-oligotrophic shallow waters and corroborates the spatial heterogeneity in these ecosystems.
