The Role of Impulsivity and Addiction in Gambling Behaviors: How Applied Neuroscience Research Can Help in the Monitoring and Management of Mental Health Issues

One in five Americans experience symptoms associated with at least one mental health disorder every year. These include behavioral addictions, which have long been overlooked despite their similar neural bases with substance addictions. Gambling addiction, a type of behavioral addiction, deserves particular attention given the significant negative effects, this addiction has on financial and interpersonal health. The purpose of this paper is to review the available literature concerning the behavioral and neural processes involved in gambling addiction, including: the anticipation of reward, the role of dopamine, and the neural substrates of the decision-making processes involved in gambling addiction. Market research has also identified solutions that integrate applied neuroscience and self-tracking systems to monitor and manage mental health issues associated with gambling addiction. The authors then propose a gambling treatment-focused mobile app solution that addresses outstanding issues with a special design aimed at reversing plasticity in order to relieve the effects of gambling addiction. .

An Edge-Fog-Cloud Computing-Based Digital Twin Model for Prognostics Health Management of Process Manufacturing Systems

The prognostics health management(PHM)fromthe systematic viewis critical to the healthy continuous operation of processmanufacturing systems(PMS),with different kinds of dynamic interference events.This paper proposes a three leveled digital twinmodel for the systematic PHMof PMSs.The unit-leveled digital twinmodel of each basic device unit of PMSs is constructed based on edge computing,which can provide real-time monitoring and analysis of the device status.The station-leveled digital twin models in the PMSs are designed to optimize and control the process parameters,which are deployed for the manufacturing execution on the fog server.The shop-leveled digital twin maintenancemodel is designed for production planning,which gives production instructions fromthe private industrial cloud server.To cope with the dynamic disturbances of a PMS,a big data-driven framework is proposed to control the three-level digital twin models,which contains indicator prediction,influence evaluation,and decisionmaking.Finally,a case study with a real chemical fiber system is introduced to illustrate the effectiveness of the digital twin model with edge-fog-cloud computing for the systematic PHM of PMSs.The result demonstrates that the three-leveled digital twin model for the systematic PHM in PMSs works well in the system’s respects.

Virtual sample generation for model-based prognostics and health management of on-board high-speed train control system

In view of class imbalance in data-driven modeling for Prognostics and Health Management(PHM),existing classification methods may fail in generating effective fault prediction models for the on-board high-speed train control equipment.A virtual sample generation solution based on Generative Adversarial Network(GAN)is proposed to overcome this shortcoming.Aiming at augmenting the sample classes with the imbalanced data problem,the GAN-based virtual sample generation strategy is embedded into the establishment of fault prediction models.Under the PHM framework of the on-board train control system,the virtual sample generation principle and the detailed procedures are presented.With the enhanced class-balancing mechanism and the designed sample augmentation logic,the PHM scheme of the on-board train control equipment has powerful data condition adaptability and can effectively predict the fault probability and life cycle status.Practical data from a specific type of on-board train control system is employed for the validation of the presented solution.The comparative results indicate that GAN-based sample augmentation is capable of achieving a desirable sample balancing level and enhancing the performance of correspondingly derived fault prediction models for the Condition-based Maintenance(CBM)operations.

Content-Based Knowledge Quality Assessment and Its Application in Health Management System

The growing demand for health management puts forward high requirements for the quality of health knowledge.A content-based method is proposed to address the current demand for high-quality health knowledge,which evaluates the quality including the certainty,accuracy,and operability of different types of knowledge from the perspectives of authority,precision,and information entropy.Herein,the health knowledge of myocardial infarction is used as an example,and knowledge is first classified into different types and then evaluated.This method is applied to knowledge in the existing health management system and it can support knowledge screening and comparison under the cold start condition.Compared with the current evaluation methods based on knowledge use behavior and utility,the new evaluation method provides a reference for evaluation when the knowledge is first used.The screening of high quality knowledge can help the subsequent application of knowledge and improve user’s compliance.Concurrently,the arrangement of myocardial infarction knowledge can also provide a knowledge reference for patients’daily health management.

Health management based on fusion prognostics for avionics systems

Health management permits the reliability of a system and plays a increasingly important role for achieving efficient system-level maintenance.It has been used for remaining useful life（RUL） prognostics of electronics-rich system including avionics.Prognostics and health management（PHM） have become highly desirable to provide avionics with system level health management.This paper presents a health management and fusion prognostic model for avionics system,combining three baseline prognostic approaches that are model-based,data-driven and knowledge-based approaches,and integrates merits as well as eliminates some limitations of each single approach to achieve fusion prognostics and improved prognostic performance of RUL estimation.A fusion model built upon an optimal linear combination forecast model is then utilized to fuse single prognostic algorithm representing the three baseline approaches correspondingly,and the presented case study shows that the fusion prognostics can provide RUL estimation more accurate and more robust than either algorithm alone.

Oral Health Management of Three Head and Neck Cancer Patients Performed by Dental Hygienists

Introduction: Oral health management is often difficult in patients after surgical tumor resection and/or radiotherapy due to defects, bulky flaps, limitation of tongue movement, and trismus. In addition, patients who have undergone radiotherapy have serious disabilities such as oral mucositis, mucosal weakening, soft tissue fibrosis, salivary gland disorder, and osteoradionecrosis. Dental hygienists must understand the characteristics of patients after surgical tumor resection and/or radiotherapy. In this report, the oral health management of three patients after maxillectomy, mandibulectomy, and radiotherapy was shown. Case Description: Case 1: A 53-year-old male patient visited our clinic after chemotherapy, radiotherapy, and partial maxillectomy for cancer of the right maxillary gingiva. Case 2: A 65-year-old male patient visited our clinic after radiotherapy for a right-sided tongue cancer, partial mandibulectomy of the right tongue to the oropharynx, a right-sided segmental mandibulectomy and a speech aid and a mandibular prosthesis were provided. Case 3: A 36-year-old female visited our clinic for radiotherapy for left-sided tongue cancer. Dental hygienists provided oral health management to the patients. In oral health management, it was suggested that intervention before cancer treatment, oral hygiene instructions tailored to patients’ symptoms, and frequent professional care are important. Conclusion: Oral health management by dental hygienists is extremely important for patients undergoing maxillofacial cancer treatment to maintain their quality of life in the long term.

The Management of Mental Health, and Service Networks in Italy

Madness has attracted and frightened for centuries,and talking about this means discussing how this diversity was built and managed in different social contexts and historical periods.Not all societies have had,and still have,the same relationship with madness.It is only with the affirmation of the Modern State,and of Capitalism,that the idea of“normality”indispensable to be able to conceive diversity as something dangerously distant and different from the norm takes over.In our post-modern society,people with mental illness in Italy can resort to specialists and social-health services.But the heterogeneous answers given after the approval of law 180 appear to be increasingly diversified.In this research,much attention will be paid to how the social and health services,located in different areas of Italy(Messina,Rome,Trento)face the current growing risk of social,housing and economic isolation of these fragile subjects.The aim of the research is to explore the possibility of a new relationship between the social-health service and the local community.On the one hand,research investigates what the contribution of the services could be.On the other what the spaces of protagonism and participation of the community could be in inclusion process account.In order to better understand the differences between these two dimensions,a qualitative research approach was chosen through the conduct of in-depth interviews.In this way it was possible to investigate:(1)the partial representations characteristic of the single individual,family members,operators and stackholders in general;(2)the services around the topic dealt with is articulated.From the first results of the research it emerges that the territory can no longer be considered as an abstract entity,but becomes the social space within which the construction of a new community welfare can and must take place.

Computational Reproducibility Within Prognostics and Health Management

Scientific research frequently involves the use of computational tools and methods.Providing thorough documentation,open-source code,and data–the creation of reproducible computational research(RCR)–helps others understand a researcher’s work.In this study,we investigate the state of reproducible computational research,broadly,and from within the field of prognostics and health management(PHM).In a text mining survey of more than 300 articles,we show that fewer than 1%of PHM researchers make their code and data available to others.To promote the RCR further,our work also highlights several personal benefits for those engaged in the practice.Finally,we introduce an open-source software tool,called PyPHM,to assist PHM researchers in accessing and preprocessing common industrial datasets.

Effects of WeChat platform-based health management on health and self-management effectiveness of patients with severe chronic heart failure

BACKGROUND Epidemiological studies have found that the prevalence of chronic heart failure in China is 0.9%,the number of people affected is more than 4 million,and the 5-year survival rate is even lower than that of malignant tumors.AIM To determine the impact of WeChat platform-based health management on severe chronic heart failure patients’health and self-management efficacy.METHODS A total of 120 patients suffering from chronic heart failure with cardiac function grade III-IV,under the classification of the New York Heart Association,were admitted to our hospital in May 2017.In January 2020,they were divided into two groups:A control group(with routine nursing intervention)and an observation group(with WeChat platform-based health management intervention).Changes in cardiac function,6-min walking distance(6MWD),high-sensitivity cardiac troponin(hs-cTnT),and N-terminal pro B-type natriuretic peptide(NT-proBNP)were detected in both groups.The Self-Care Ability Scale(ESCA)score,Minnesota Living with Heart Failure Questionnaire score,and compliance score were used to evaluate self-management ability,quality of life,and compliance of the two groups.During a follow-up period of 12 mo,the occurrence of cardiovascular adverse events in both the groups was counted.RESULTS The left ventricular ejection fraction,stroke output,and 6MWD increased,and the hs-cTnT and NT-proBNP decreased in both the groups,as compared to those before the intervention.Further,cardiac function during the 6MWD,hs-cTnT,and NT-proBNP improved significantly in the observation group after intervention(P<0.05).The scores of self-care responsibility,self-concept,self-care skills,and selfcare health knowledge in the observation group were higher than those of the control group before intervention,and their ESCA scores were significantly improved after intervention(P<0.05).The Minnesota heart failure quality of life(LiHFe)scores of physical restriction,disease symptoms,psychological emotion,social relations,and other items were decreased compared to those of the control group before intervention,and the LiHFe scores of the observation group were significantly improved compared to those of the control group(P<0.05).With intervention,the compliance scores of rational diet,regular medication,healthy behavior,and timely reexamination were increased,thereby leading to the compliance scores of the observation group being significantly improved compared to those of the control group(P<0.05).During the 12 mo follow-up,the incidence rates of acute myocardial infarction and cardiogenic rehospitalization in the observation group were lower than those of the control group,and the hospitalization time in the observation group was shorter than that of the control group,but there was no significant difference between the two groups(P>0.05).CONCLUSION WeChat platform-based health management can improve the self-care ability and compliance of patients with severe chronic heart failure,improve the cardiac function and related indexes,reduce the occurrence of cardiovascular adverse events,and enable the avoidance of rehospitalization.

Optimization of dynamic sequential test strategy for equipment health management

Testing is the premise and foundation of realizing equipment health management （EHM）. To address the problem that the static periodic test strategy may cause deficient test or excessive test, a dynamic sequential test strategy （DSTS） for EHM is presented. Considering the situation that equipment health state is not completely observable in reality, a DSTS optimization method based on partially observable semi-Markov decision pro- cess （POSMDP） is proposed. Firstly, an equipment health state degradation model is constructed by Markov process, and the control limit maintenance policy is also introduced. Secondly, POSMDP is formulated in great detail. And then, POSMDP is converted to completely observable belief semi-Markov decision process （BSMDP） through belief state. The optimal equation and the corresponding optimal DSTS, which minimize the long-run ex- pected average cost per unit time, are obtained with BSMDP. The results of application in complex equipment show that the proposed DSTS is feasible and effective.

Preventive online and offline health management intervention in polycystic ovary syndrome

BACKGROUND Polycystic ovary syndrome(PCOS) is characterized by hyperandrogenism, hyperinsulinemia, ovarian polycystic changes, and irregular ovulation, often occurring in women of childbearing age for whom it can be a cause of infertility. Hypothalamus-pituitary-ovarian axis dysregulation is important in the pathogenesis of PCOS and the associated chronic excess of sex hormones can lead to cardiovascular and cerebrovascular diseases, diabetes, and malignancies such as endometrial cancer, and breast cancer. At present, most scholars agree that lifestyle interventions in conjunction with drug treatment can help PCOS patients achieve their goals of successful pregnancy and childbirth.AIM To investigate the clinical effect of an online and offline(O2O) preventive health management model on PCOS with kidney deficiency and phlegm dampness.METHODS A total of 82 patients with PCOS of the kidney deficiency and phlegm dampness type who were admitted to Beijing Luhe Hospital Affiliated to Capital Medical University from April 2019 to June 2020 were randomly divided into two groups. The treatment group was treated with oral Diane-35 for 3 mo and received preventive O2O medical health management for 6 mo(including eating and living, exercise, drug management). The control group was treated with oral Diane-35 for 3 mo and completed outpatient health education. The traditional Chinese medicine(TCM) syndrome score, acne score, hair score, sex hormone level and clinical effects were compared between the two groups before and after the intervention. RESULTS After treatment, the TCM syndrome score, acne score, and serum luteinizing hormone/follicle stimulating hormone level were significantly lower in the treatment group than in the control group(P < 0.05). After 3 mo of treatment, the TCM syndrome curative effect index in the treatment group was 97.30% compared to 54.05% in the control group(P < 0.05), whereas the total treatment effect in the treatment group was 91.89%, compared to 54.05% in the control group(P < 0.05).CONCLUSION An integrated therapeutic approach incorporating medication, TCM methods and social media is more effective than standard treatment for PCOS.
