A prolonged course of ADT can increase toxicity and drug resistance. This study proposes an adaptive therapy combining chemotherapy or immunotherapy with the discontinuation of hormone therapy to overcome these obstacles. The super-twisting sliding mode control (STSMC) algorithm is found to be one of the effective approach as an ADT model for obtaining suitable dosage adaptively. The primary objective is to rapidly reduce the number of cancer cells and the duration of drug exposure. The Takagi–Sugeno fuzzy controller-based active control algorithm is introduced, and it’s performance is compared with the STSMC algorithm. While maintaining global asymptotic stability, the Takagi–Sugeno fuzzy controller reduces the duration of therapy to six months. The controllers are implemented utilizing the linear matrix inequality (LMI) algorithm and the yet another LMI (YALMIP) toolset for MATLAB, and their efficacy is validated utilizing MATLAB and Simulink simulations. This study presents a novel approach to improve prostate cancer treatment outcomes by integrating nonlinear control algorithms and adaptive dosage strategies to reduce treatment duration and minimize drug exposure, thereby improving patient outcomes in prostate cancer management.</p></div>","PeriodicalId":73222,"journal":{"name":"Healthcare analytics (New York, N.Y.)","volume":"4 ","pages":"Article 100277"},"PeriodicalIF":0.0,"publicationDate":"2023-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772442523001442/pdfft?md5=81f62be5bb321786dbef53786aa8cf17&pid=1-s2.0-S2772442523001442-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"109127163","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To gain a greater breadth of up-to-date insights, hospitals and researchers must either pay for third party services or acquire the appropriate expertise. To democratize insights into cost report data, we first developed an open-source public repository of 6908 hospital-specific dataset, each containing 2843 labeled features and spanning years between 2010 and 2023. We then developed an open-source application for analyzing and downloading these data.

Web interest and concern in COVID-19 vaccines over the past week (January 8–14, 2023) was investigated via the websites Google Trends and Talkwalker by searching for appropriate keywords. Thanks to the analysis of related queries and topics, it was possible to determine and examine the most debated topics relating to specific side effects. Emotional reactions regarding COVID-19 vaccines have been negative in varying percentages between 40 and 70 %, depending on the topic discussed. Feelings of alarm, derision, doubt, and anger were common (about 60 %). The concerns were mainly about the effectiveness against recent COVID-19 variants and alleged side effects such as sudden death, tumors, myocarditis, prion disease, and high ferritin. The most used media among those scrutinized was Twitter (over 90 % of interactions). The male audience participated more and showed more negativity than the female one. The age groups mainly involved were the under-45s. This research discussed the combined use of Google Trends and Talkwalker to conduct rapid infoveillance surveys.

The prevalence of diabetes mellitus, in particular Type 2 Diabetes (T2D), is rising dramatically globally. Several clinical trials provide evidence that lifestyle interventions can prevent or delay the development of T2D, but the impact of lifestyle interventions is seldom investigated using a mathematical model. This study assesses the effects of lifestyle interventions on people by constructing an ordinary differential equation model. In this paper, a general model is developed based on the dynamics of T2D by incorporating a control variable termed as healthy lifestyle. The population is subdivided into five classes: susceptible, affected, treated, healthy lifestyle, and prevented. Sensitivity analysis has been performed to identify the most important parameters, and the stability of the equilibrium point is analyzed. Numerical simulations are conducted using a diabetes data set in Bangladesh to investigate the model's dynamic behavior. The results from this study reveal that maintaining a healthy lifestyle slows disease progression. The sensitivity analysis shows that the healthy lifestyle rate, treatment rate, and diabetes rate from susceptible and healthy lifestyle classes are the most sensitive parameters. Moreover, the study also concludes that diabetes cannot completely be eliminated, but with proper control measures, the burden can be reduced. The findings from the study provide strong reasons to continue implementing lifestyle interventions to prevent the global epidemic and its adverse effects.</p></div>","PeriodicalId":73222,"journal":{"name":"Healthcare analytics (New York, N.Y.)","volume":"4 ","pages":"Article 100271"},"PeriodicalIF":0.0,"publicationDate":"2023-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49899305","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it is essential to study the transmission dynamics of the disease, considering the factors that contribute to the strain’s impact on the disease burden, using an epidemiological model. We present a deterministic mathematical model that explores the dynamics of TB with two strains: drug-susceptible and drug-resistant, taking into account exogenous re-infection. We thoroughly analyze to gain insights into the behavior of the model. The qualitative analysis of the model reveals an interesting phenomenon known as “backward bifurcation,” where both stable disease-free and stable endemic equilibria coexist when the associated reproduction number is less than one. In the absence of exogenous re-infection, the model shows the existence of unique positive endemic equilibria. Numerical simulations were conducted, yielding noteworthy results. Increasing the treatment rate for individuals infected with the drug-susceptible strain reduces the number of new cases of drug-susceptible TB while increasing the detection of drug-resistant TB cases. The simulations demonstrate that drug-susceptible and drug-resistant TB strains can coexist when their reproduction numbers exceed one without competitive exclusion occurring. In summary, this study sheds light on the challenges posed by drug resistance in TB treatment and highlights the importance of understanding the disease dynamics through mathematical modeling to develop effective strategies for its control.</p></div>","PeriodicalId":73222,"journal":{"name":"Healthcare analytics (New York, N.Y.)","volume":"4 ","pages":"Article 100266"},"PeriodicalIF":0.0,"publicationDate":"2023-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49899308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
