Sharing patient datasets curated by health institutions is critical for the advance of monitoring, surveillance and research. Selleck Alizarin Red S However, patient data is sensitive data and it can only be released under certain conditions and with previous explicit consent. Privacy preserving data sharing provides techniques to distribute datasets minimizing the risk of identification of patients. However, the sharing of datasets is typically done without considering the needs or requests of data consumers. Blockchain technologies provide an opportunity to gather those requests and share and assemble datasets using privacy-preserving methods as data and requirements on anonymity match. The architecture and design of such a solution is described, assuming an underlying permissioned blockchain network where providers such as healthcare institutions deal with consent, patient preferences and anonymity guarantees, playing a mediator role to a network of organizations.The blood-brain barrier plays a crucial role in regulating the passage of 98% of the compounds that enter the central nervous system (CNS). Compounds with high permeability must be identified to enable the synthesis of brain medications for the treatment of various brain diseases, such as Parkinson's, Alzheimer's, and brain tumors. Throughout the years, several models have been developed to solve this problem and have achieved acceptable accuracy scores in predicting compounds that penetrate the blood-brain barrier. However, predicting compounds with "low" permeability has been a challenging task. In this study, we present a deep learning (DL) classification model to predict blood-brain barrier permeability. The proposed model addresses the fundamental issues presented in former models high dimensionality, class imbalances, and low specificity scores. We address these issues to enhance the high-dimensional, imbalanced dataset before developing the classification model the imbalanced dataset is addressed using oversampling techniques and the high dimensionality using a non-linear dimensionality reduction technique known as kernel principal component analysis (KPCA). This technique transforms the high-dimensional dataset into a low-dimensional Euclidean space while retaining invaluable information. For the classification task, we developed an enhanced feed-forward deep learning model and a convolutional neural network model. In terms of specificity scores (i.e., predicting compounds with low permeability), the results obtained by the enhanced feed-forward deep learning model outperformed those obtained by other models in the literature that were developed using the same technique. In addition, the proposed convolutional neural network model surpassed models used in other studies in multiple accuracy measures, including overall accuracy and specificity. The proposed approach solves the problem inevitably faced with obtaining low specificity resulting in high false positive rate.The Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) survey has received increased attention to determine which demographics may influence patient satisfaction after Total Hip and Knee Arthroplasty. The purpose of this study was to evaluate the various effects that patient-specific factors, medical comorbidities, and demographics had on patient satisfaction. Two thousand and ninety-two patients underwent lower extremity total joint arthroplasty at our institution between 2014 and 2018. Nine hundred twenty-three of these patients responded to their HCAHPS survey (44%). Most patients (609, 66%) underwent primary total knee arthroplasty followed by 244 (26.4%) total hip arthroplasties, 35 (3.8%) revision total knee arthroplasties, 28 (3.0%) bilateral total knee arthroplasties, and 7 (0.8%) revision total hip arthroplasties. Increasing age and length of stay were associated with a decrease in patient satisfaction whereas patients who were married reported higher satisfaction. Patients discharged to a rehabilitation facility had a 12% decrease in top-box response rate compared to those discharged home. Contrary to our hypothesis, specific procedure type and the presence of comorbidities failed to predict patient satisfaction. The results of this study shed light on the intricate relationship between patient satisfaction and patient-specific factors. Furthermore, health care workers can counsel patients on expected satisfaction when considering total hip and knee arthroplasty.Millions of Americans live with dementia. Caregivers of this population provide countless hours of multifaceted, complex care that frequently cause unrelenting stress which can result in immense burden. However, it is not fully understood what efforts can be made to reduce the stress among caregivers of persons with dementia (PWD). Therefore, the aim of this pretest-posttest designed study was to evaluate changes in caregiver burden after providing an educational intervention to those caring for PWD in Arkansas. Forty-one participants completed the Zarit Caregiver Burden Scale before and after attending a 4-hour dementia-focused caregiving workshop. The analysis of the means, standard deviations, and paired t tests showed that there was an increase in the confidence and competence in caring for PWD 30 to 45 days after attending the workshop. Health care providers need to understand both the vital role caregivers provide in managing a PWD and the importance of the caregiver receiving education about their role as a caregiver. Utilizing caregiver educational programs is a first step.Outpatient clinics are an important part of chronic disease management, including that of celiac disease. During the coronavirus disease 2019 (COVID-19) global pandemic, telephone and online video consultations with health care professionals have substantially increased. This study aimed to explore the experience and opinions of adults, with celiac disease, toward face-to-face clinic appointments and alternatives, such as telehealth. Semistructured qualitative interviews with 37 patients were undertaken (75% White Caucasians, 25% South Asians; 29 patients were not adhering to the gluten-free diet). Interviews were recorded, transcribed, and analyzed by NVivo. Frequently reported issues with face-to-face appointments included travel and car parking costs, needing to take time off work, and frequent changes to appointment time. In addition, South Asian patients highlighted issues with linguistics barriers. Telephone consultations were considered acceptable and practical by the majority of patients based on ease and convenience.
