Self-Care in Diabetes as perceived by diabetic patients – A Systematic Qualitative Approach

Background: India is one of several developing nations where diabetes mellitus has grown to be a severe global public health concern. The individual, medical staff, and healthcare system are all subject to a heavy burden of care. As a result, there is a huge need of self-care practices in a variety of domains, such as nutrition, exercise, foot care, and blood sugar monitoring. Objectives: To determine perceptions regarding self-care management among individuals with Type 2 Diabetes mellitus following up at rural field practice areas of a tertiary care institute in Mangaluru. Materials and methods: Qualitative study using systematic technique by free listing approach was carried out on a total of forty patients confirmed type 2 Diabetes. By consecutive sampling 20 patients each from 2 field practice areas of a Tertiary medical institute were taken. Results: The general reason leading on to the diagnosis of diabetes stated was tiredness which had a composite salience of 0.48. The composite salience for self-care practice was 0.48. Participants stating that diabetes can be controlled had a composite salience of 0.3. Conclusion: Perception regarding self-care included diet, foot care, stress reduction and exercise with majority mentioning that diabetes can be controlled by these self -care mechanisms.

Genetic switch selectively kills hepatocellular carcinoma cell based on microRNA and tissue-specific promoter

The clinical treatment of hepatocellular carcinoma (HCC) is still a heavy burden worldwide. Intracellular microRNAs (miRNAs) commonly express abnormally in cancers, thus they are potential therapeutic targets for cancer treatment. miR-21 is upregulated in HCC whereas miR-122 is enriched in normal hepatocyte but downregulated in HCC. In our study, we first generated a reporter genetic switch compromising of miR-21 and miR-122 sponges as sensor, green fluorescent protein (GFP) as reporter gene and L7Ae:K-turn as regulatory element. The reporter expression was turned up in miR-21 enriched environment while turned down in miR-122 enriched environment, indicating that the reporter switch is able to respond distinctly to different miRNA environment. Furthermore, an AAT promoter, which is hepatocyte-specific, is applied to increase the specificity to hepatocyte. A killing switch with AAT promoter and an apoptosis-inducing element, Bax, in addition to miR-21 and miR-122 significantly inhibited cell viability in Huh-7 by 70 % and in HepG2 by 60 %. By contrast, cell viability was not affected in five non-HCC cells. Thus, we provide a novel feasible strategy to improve the safety of miRNA-based therapeutic agent to cancer.

The PROgnostic ModEl for chronic lung disease (PRO-MEL): development and temporal validation

BackgroundPatients with chronic lung diseases (CLDs), defined as progressive and life-limiting respiratory conditions, experience a heavy symptom burden as the conditions become more advanced, but palliative referral rates are low and late. Prognostic tools can help clinicians identify CLD patients at high risk of deterioration for needs assessments and referral to palliative care. As current prognostic tools may not generalize well across all CLD conditions, we aim to develop and validate a general model to predict one-year mortality in patients presenting with any CLD.MethodsA retrospective cohort study of patients with a CLD diagnosis at a public hospital from July 2016 to October 2017 was conducted. The outcome of interest was all-cause mortality within one-year of diagnosis. Potential prognostic factors were identified from reviews of prognostic studies in CLD, and data was extracted from electronic medical records. Missing data was imputed using multiple imputation by chained equations. Logistic regression models were developed using variable selection methods and validated in patients seen from January 2018 to December 2019. Discriminative ability, calibration and clinical usefulness of the model was assessed. Model coefficients and performance were pooled across all imputed datasets and reported.ResultsOf the 1000 patients, 122 (12.2%) died within one year. Patients had chronic obstructive pulmonary disease or emphysema (55%), bronchiectasis (38%), interstitial lung diseases (12%), or multiple diagnoses (6%). The model selected through forward stepwise variable selection had the highest AUC (0.77 (0.72–0.82)) and consisted of ten prognostic factors. The model AUC for the validation cohort was 0.75 (0.70, 0.81), and the calibration intercept and slope were − 0.14 (-0.54, 0.26) and 0.74 (0.53, 0.95) respectively. Classifying patients with a predicted risk of death exceeding 0.30 as high risk, the model would correctly identify 3 out 10 decedents and 9 of 10 survivors.ConclusionsWe developed and validated a prognostic model for one-year mortality in patients with CLD using routinely available administrative data. The model will support clinicians in identifying patients across various CLD etiologies who are at risk of deterioration for a basic palliative care assessment to identify unmet needs and trigger an early referral to palliative medicine.Trial registrationNot applicable (retrospective study).

Fighting sepsis-induced liver damage with biosynthesized silver nanoparticles.

Sepsis is a potentially fatal disease that arises from an infection and is characterized by an uncontrolled immune system reaction. Global healthcare systems bear a heavy financial burden from treating sepsis. This study aimed to provide information on the effective properties of silver nanoparticles derived from pomegranate peel extract (P-AgNP) against sepsis-induced hepatic injury. P-AgNPs were spherical with a diameter of ~19 nm. The animals were placed into four groups, each with seven rats. Group 1 functioned as the control group, receiving only saline for 7 days. Group 2 received only P-AgNPs at a dose of 20 mg/kg. To induce sepsis, groups 3 and 4 were given an intraperitoneal injection of 200 mg/mL cecal slurry. Sixty min later, group 4 was given 20 mg/kg of P-AgNPs daily for 7 days. The concentrations of reduced glutathione, nitric oxide, lipid peroxidation, and superoxide dismutase in liver homogenate were measured to determine the oxidative status. In addition, enzyme activities (alanine aminotransferase, aspartate amino transferase, and alkaline phosphatase) were measured. Furthermore, we investigated the histological changes, immunohistochemical expression of nuclear factor-κB, and mRNA levels of IL1β, IL-6, TNF-α, Bax, BCl2, and Casp-3. P-AgNPs functioned as regulators in a sepsis model, successfully controlling altered gene expression. Following treatment, P-AgNPs improved tion and oxidative state, indicating a role in sepsis management. Based on our findings, we conclude that P-AgNPs have antioxidant activity and may be useful in preventing sepsis-induced liver inflammation, oxidative damage, and apoptosis. RESEARCH HIGHLIGHTS: Pomegranate peel-derived silver nanoparticles (P-AgNPs) enhanced liver function and oxidative state in rats with sepsis-induced hepatic damage. P-AgNPs reduced oxidative stress and liver inflammation via regulating inflammatory and apoptotic gene expression. P-AgNPs enhanced liver enzyme activities, histological structure, and immunohistochemistry expression of nuclear factor-κB.

Quercetin alleviates depressive-like behavior by modulating acetyl-H3K9 mediated ferroptosis pathway in hypothalamus of perimenopausal depression rat model

Perimenopausal depression is a subtype of depression and is prevalent among perimenopausal women, which has brought a heavy burden to family and society. The pathogenesis of perimenopausal depression is still unclear, which affects the prevention and treatment of perimenopausal depression to a certain extent. Quercetin is a flavonoid compound, and has estrogenic activity and pharmacological effects such as antioxidant, anti-inflammatory, and neuroprotective effects. This study investigated whether quercetin improved perimenopausal depression-like behaviors and potential mechanism. The results demonstrated that quercetin could alleviate the depression-like behaviors in perimenopausal depression rat model, inhibit astrocyte activation, improve ferroptosis-associated mitochondrial damage (such as mitochondrial pyknosis and mitochondrial cristae reduction) in hypothalamus, increase the expressions of histone 3 lysine 9 acetylation (acetyl-H3K9), ferroptosis-associated protein including glutathione peroxidase 4 (GPX4) and Xc- antiporter (SLC7A11), and reduce the expressions of endoplasmic reticulum stress-related proteins including inositol-requiring enzyme 1 (IRE1α), phosphorylated IRE1α (p-IRE1α), X-box binding protein 1 (XBP1) and glucose-regulated protein 78 (GRP78) in hypothalamus of perimenopausal depression rat model. Furtherly, in vitro study indicated that quercetin could restore histone acetylase (HAT)/histone deacetylase (HDAC) homeostasis through binding to estrogen receptors and increase the expression of acetyl-H3K9, inhibiting ferroptosis through IRE1α/XBP1 pathway in astrocytes of hypothalamus. Our findings demonstrated that acetyl-H3K9 is a crucial target in development of perimenopausal depression, and quercetin exhibited antidepressant effects through modulating acetyl-H3K9 mediated ferroptosis in perimenopausal depression. Quercetin might be the prevention and adjuvant treatment strategy of perimenopausal depression.

Disaster scenes as a foundation for emergency response planning

This article introduces the notion of ‘disaster scenes’. In this work, we draw on interview data collected from residents impacted by the Jagersfontein tailings disaster in South Africa in September 2022. Our methodological aim is to reconstruct the experiences of impacted people in the format of empirically derived disaster scenes. These scenes provide a credible source for modelling scenarios because they showcase the prior, immediate, response and long-term recovery phases of disaster management. Studies that provide empirical detail on the lived experience of disasters confirm the heavy burden placed on impacted people largely originating from institutional decisions. The overarching empirical narrative from this case and other cognate cases is that the absence of state institutions is a factor that likely contributes to disaster events. Our argument is that sharing information that includes models of state default can empower potentially affected groups to demand safeguards and greater transparency in relation to the operation and regulation of tailings facilities.

Frequency of use and cost in Japan of first-line palliative chemotherapies for recurrent or metastatic squamous cell carcinoma of the head and neck.

Over the last decade, novel anticancer drugs have improved the prognosis for recurrent or metastatic squamous cell carcinoma of the head and neck (RM-SCCHN). However, this has increased healthcare expenditures and placed a heavy burden on patients and society. This study investigated the frequency of use and costs of select palliative chemotherapy regimens in Japan. From July 2021 to June 2022 in 54 healthcare facilities, we gathered data of patients diagnosed with RM-SCCHN and who had started first-line palliative chemotherapy with one of eight commonly used regimens. Patients with nasopharyngeal carcinomas were excluded. The number of patients receiving each regimen and the costs of each regimen for the first month and per year were tallied. The sample comprised 907 patients (674 were<75years old, 233 were≥75years old). 330 (36.4%) received Pembrolizumab monotherapy, and 202 (22.3%) received Nivolumab monotherapy. Over 90% of patients were treated with immune checkpoint inhibitors as monotherapy or in combination with chemotherapy. Treatment regimens' first-month costs were 612 851-849 241 Japanese yen (JPY). The cost of standard palliative chemotherapy until 2012 was about 20 000 JPY per month. The incremental cost over the past decade is approximately 600 000-800 000 JPY per month, a 30- to 40-fold increase in the cost of palliative chemotherapy for RM-SCCHN. First-line palliative chemotherapy for RM-SCCHN exceeds 600 000 JPY monthly. Over the last decade, the prognosis for RM-SCCHN has improved, but the costs of palliative chemotherapy have surged, placing a heavy burden on patients and society.

Artificial intelligence in myopia in children: current trends and future directions.

Myopia is one of the major causes of visual impairment globally, with myopia and its complications thus placing a heavy healthcare and economic burden. With most cases of myopia developing during childhood, interventions to slow myopia progression are most effective when implemented early. To address this public health challenge, artificial intelligence has emerged as a potential solution in childhood myopia management. The bulk of artificial intelligence research in childhood myopia was previously focused on traditional machine learning models for the identification of children at high risk for myopia progression. Recently, there has been a surge of literature with larger datasets, more computational power, and more complex computation models, leveraging artificial intelligence for novel approaches including large-scale myopia screening using big data, multimodal data, and advancing imaging technology for myopia progression, and deep learning models for precision treatment. Artificial intelligence holds significant promise in transforming the field of childhood myopia management. Novel artificial intelligence modalities including automated machine learning, large language models, and federated learning could play an important role in the future by delivering precision medicine, improving health literacy, and allowing the preservation of data privacy. However, along with these advancements in technology come practical challenges including regulation and clinical integration.

Corporate Tax Planning and Financial Performance of Listed Consumer Goods in Nigeria

The multiplicity of tax laws and heavy tax burden facing companies in developing countries such as Nigeria has resulted in the adoption of different strategies to reduce tax liabilities. The main objective of this study therefore was to examine the effect of tax planning on financial performance of listed consumer goods firms in Nigeria from 2013 to 2022. The measures of tax planning adopted in this study were effective tax rate, tax incentives, debt tax shield and capital intensity. Return on assets was the measure of financial performance. The research design adopted for this study was ex-post facto because secondary data was used. The population of this study consisted of 21 listed consumer goods companies in Nigeria and purposive sampling technique was employed to select 18 of these companies. The ordinary least square regression technique was used to analyze the data and the statistical package employed was E-views version 10. The findings of the study revealed that effective tax rate has a negative and insignificant effect on the return on assets (ROA); tax incentives has a significant positive effect on return on assets; debt tax shield has significant and positive effect on return on assets; capital intensity has a positive but insignificant effect on return on assets of listed consumer goods firms in Nigeria. Thus, it was concluded that tax planning activities impact on the financial performance of listed consumer goods firms in Nigeria. Based on the above it was recommended among others that the management of consumer goods companies should focus on long term tax planning rather than solely concentrating on reducing effective tax rate. The management of consumer goods companies should also explore and take full advantage of available tax incentives by capitalizing on applicable tax incentives provided by the regulatory environment.

Hypertension status and its risk factors in highlanders living in Ganzi Tibetan Plateau: a cross-sectional study

BackgroundThe updated status of hypertension and its risk factors are poorly evaluated in Tibetan highland areas. We initiated a large-scale cross-sectional survey to provide updated status of hypertension and its risk factors (especially salt intake) in the Ganzi Tibetan Plateau, China.MethodsStratified multistage random sampling was performed to obtain a representative sample of 4,036 adult residents from 4 counties in the Ganzi Tibetan area. The whole survey population was used to present the epidemiology and risk factors of hypertension. The participants with blood and urine biochemistry data were used to analyze the relationship between salt intake parameters and hypertension.ResultsStratified multistage random sampling was performed to obtain a representative sample of 4,036 adult residents. The overall prevalence rate of hypertension was 33.5% (the age-adjusted prevalence rate was 28.9%). A total of 50.9% of the hypertensive patients knew their conditions; 30.1% of them received antihypertensive treatment; and 11.2% of them had their blood pressure controlled. Age, male sex, living altitude ≥ 3500 m, overweight and abdominal obesity were positively correlated with hypertension. In addition, the adjusted odds ratio (OR) for hypertension was 1.33 (95% CI: 1.01–1.74) for drinking tea with salt, and 1.51 (95% CI: 1.32–1.72) for per SD increase in the estimation of 24-hour urinary sodium excretion (e24hUSE). Furthermore, per 100mmol/day increase in e24hUSE was associated with elevation of blood pressure (+ 10.16, 95% CI: 8.45–11.87 mmHg for SBP; +3.83, 95% CI: 2.74–4.93 mmHg for DBP) in this population.ConclusionsOur survey suggests a heavy disease burden of hypertension in the Ganzi Tibetan Plateau. Age, male sex, altitude of residence ≥ 3500 m, overweight, abdominal obesity, and excessive salt intake (shown as drinking tea with adding salt and a higher level of e24hUSE) all increased the risk of hypertension in this highland area.

The essence of ESG projects, the specifics of risks and profitability

Numerous global problems of our time pose a challenge to the world community. It is obvious that the risks of unsustainable development create a potentially heavy burden for future generations, depriving them of the opportunity to develop on an equal basis with the current generation. These risks require all economic agents to be more active in purposefully ensuring sustainable development. In this regard, the study of mechanisms in the field of ensuring sustainable development of Russia is especially important. In this study, the emphasis was placed on studying the essence of ESG projects and their financial component. The authors reviewed the main types of ESG projects; systematized the risks inherent in their implementation; We figured out the definition of “profitability” of an ESG project.

The economic cost of direct smoking in South Korea

BackgroundSmoking not only causes negative health outcomes for individuals but also causes an economic burden to society. This study estimated the socioeconomic costs of direct smoking in South Korea in 2020. MethodsWe used the prevalence-based cost-of-illness approach to estimate the sum of the direct (medical, transportation, and caregiving) and indirect (productivity loss due to health service utilization and premature death) costs of 41 smoking-related diseases. We assumed that diseases with death-based hazard ratios greater than 1.0 were related to smoking and used them in cost estimation. ResultsThe socioeconomic cost of direct smoking in Korea was USD 10.9 billion in 2020, accounting for 0.67 % of the gross domestic product and 8.0 % of current health expenditures. The direct cost was USD 4,172 million and the indirect cost was USD 6,753 million. The cost of productivity loss due to premature death took up the largest amount of the total cost, accounting for 52.3 %. The amount attributed to males accounted for 90.4 % of the overall cost, totaling to USD 9,877 million. This is attributable to higher smoking rates and higher medical costs in men. Cancer costs accounted for 40.0 % of the total cost, causing the greatest burden of diseases. ConclusionDirect smoking imposed a harmful and heavy economic burden on South Korea. Our estimate provides the latest evidence on the financial burden of smoking and strengthens the case for strong tobacco control policies and interventions.

The role of short-chain fatty acids in the regulation of osteoporosis: new perspectives from gut microbiota to bone health: A review.

Osteoporosis is a systemic skeletal disease characterized by low bone density and microarchitectural deterioration, resulting in increased fracture risk. With an aging population, osteoporosis imposes a heavy burden worldwide. Current pharmacotherapies such as bisphosphonates can reduce fracture risk but have limitations. Emerging research suggests that gut microbiota regulates bone metabolism through multiple mechanisms. Short-chain fatty acids (SCFAs) produced from microbial fermentation of dietary fiber beneficially impact bone health. Preclinical studies indicate that SCFAs such as butyrate and propionate prevent bone loss in osteoporosis models by inhibiting osteoclastogenesis and immune modulation. Early clinical data also suggest that SCFA supplementation may improve bone turnover markers in postmenopausal women. SCFAs likely act via inhibition of osteoclast differentiation, stimulation of osteoblast activity, regulation of T cells, and other pathways. However, optimal dosing, delivery methods, and long-term safety require further investigation. Modulating the gut-bone axis via supplementation, prebiotics/probiotics, diet, and lifestyle interventions represents an innovative therapeutic approach for osteoporosis. Harnessing the interplay between microbiome, metabolism, immunity, and bone may provide new directions for managing osteoporosis in the future.

Expert recommendations on screening, testing and management for hepatitis B virus infection in adults

The prevalence of hepatitis B represents a significant public health concern with a heavy disease burden. In China, there is still a big gap between the current diagnosis and treatment rates of hepatitis B and the goal of eliminating viral hepatitis as a public health threat by 2030 set by the World Health Organization (WHO). In order to achieve the WHO goal and the goal of 2030 Healthy China Outline, the Chinese Preventive Medicine Association organized domestic experts in the fields of clinical medicine, public health and clinical laboratory medicine to develop the Expert Recommendations on Screening, Testing and Management for Hepatitis B Virus Infection in Adults after several rounds of discussion based on comprehensive review of relevant domestic and international guidelines and literatures, the purpose is to facilitate universal screening of hepatitis B virus(HBV)infection in adults and provide practical guidance on disease assessment, treatment and long-term follow-up management of people infected with HBV and vaccination for people susceptible to HBV infection,thus promoting the elimination of the threat of hepatitis B.

Nifuroxazide Prevents Chikungunya Virus Infection Both In Vitro and In Vivo via Suppressing Viral Replication.

Chikungunya virus (CHIKV) is a reemerging arbovirus causing disease on a global scale, and the potential for its epidemics remains high. CHIKV has caused millions of cases and heavy economic burdens around the world, while there are no available approved antiviral therapies to date. In this study, nifuroxazide, an FDA-approved antibiotic for acute diarrhea or colitis, was found to significantly inhibit a variety of arboviruses, although its antiviral activity varied among different target cell types. Nifuroxazide exhibited relatively high inhibitory efficiency in yellow fever virus (YFV) infection of the hepatoma cell line Huh7, tick-borne encephalitis virus (TBEV) and west nile virus (WNV) infection of the vascular endothelial cell line HUVEC, and CHIKV infection of both Huh7 cells and HUVECs, while it barely affected the viral invasion of neurons. Further systematic studies on the action stage of nifuroxazide showed that nifuroxazide mainly inhibited in the viral replication stage. In vivo, nifuroxazide significantly reduced the viral load in muscles and protected mice from CHIKV-induced footpad swelling, an inflammation injury within the arthrosis of infected mice. These results suggest that nifuroxazide has a potential clinical application as an antiviral drug, such as in the treatment of CHIKV infection.

Auditory System Injury on the Battlefield-Solutions for Point-of-Injury and Prolonged Casualty Care: A DOTmLPF-P Analysis.

"Good hearing" (DoDI 6030.03 6.5&6.6) is a combat multiplier, critical to service members' lethality and survivability on the battlefield. Exposure to an explosive blast or high-intensity continuous noise is common in operational settings with the potential to compromise both hearing and vestibular health and jeopardize safety and high-level mission performance. The Joint Trauma System Acoustic Trauma Clinical Practice Guideline was published in 2018, providing recommendations for the assessment and treatment of aural blast injuries and acoustic trauma in the forward deployed environment. Combat care capabilities responsive to current threat environments emphasize prolonged casualty care. Despite recommendations, auditory system health has not been assessed routinely or in its entirety on the battlefield. This is due primarily to the large footprint of an audiometric booth and to the heavy logistical burden of providing high-quality, comprehensive auditory system (including vestibular) examinations in the combat environment. The Defense Health Agency Hearing Center of Excellence has completed a Doctrine, Organization, Training, Materiel, Leadership & Education, Personnel, Facilities, and Policy (DOTmLPF-P) analysis of battlefield auditory system assessment and treatment, using 67 existing DoD documents and artifacts related to operational medicine. Our analysis found that acoustic trauma is generally not addressed in any of the DOTmLPF-P domains. We recommend that auditory system assessment and treatment be incorporated across the continuum of care on the battlefield. This should be addressed through Prolonged Field Care and Tactical Combat Casualty Care guidance and in all Tactical Combat Casualty Care training programs. Equipment sets should be modified to include boothless technology and associated materiel for auditory system assessment. Policy and Doctrine changes would be required to mandate and support the implementation of these services. Uniformed audiologists should be added to the organizational structure at role 3 or higher to provide direct patient care; consult with other health care providers and commanders; develop and support enforcement of noise hazard guidelines; track hearing readiness; and, when necessary, provide specialized hearing protection devices that can compensate for hearing loss. These recommendations aim to help the DoD bring about necessary assessments and interventions for acoustic trauma so that service members can have better hearing outcomes and maintain critical auditory system function on the battlefield.

A comprehensive review of deep learning-based models for heart disease prediction

Heart disease (HD) is one of the leading causes of death in humans, posing a heavy burden on society, families, and patients. Real-time prediction of HD can reduce mortality rates and is crucial for timely intervention and treatment of HD. Deep learning (DL)-related methods have higher accuracy and real-time performance in predicting HD. In this study, we comprehensively compared and evaluated the contributions and limitations of DL algorithms, extended deep learning (ETDL) algorithms, and integrated deep learning (integrated DL) algorithms that combine DL with other technologies for predicting HD. The articles considered span the period from 2018 to 2023, and after rigorous screening, 64 articles were selected for preliminary research. A systematic literature review of real-time HDP will provide future researchers with a comprehensive understanding of existing deep learning methods and related integrated technologies in the healthcare industry. Furthermore, it discusses popular datasets employed in deploying numerous prediction models. Additionally, it reveals existing open problems or challenges encountered by previous researchers. Notably, the most prevalent challenge is the scarcity of large discrete datasets, followed by the need for further improvement of existing models.

Causes and predictors of recurrent unplanned hospital admissions in heart failure patients: a cohort study.

Despite progress in therapy, heart failure (HF) inflicts a heavy burden of hospital admissions. In this study, we identified among 1360 community-dwelling HF patients (mean age 70.7 ± 11.3 years, 72.5% men) subgroups sharing similar profiles of unplanned hospital admissions, based on the admission causes and frequency of each cause. Hospital discharge summaries were reviewed for the main admission cause. Patient subgroups were identified via cluster analysis. We investigated baseline predictors associated with these subgroups, using multinomial logistic models. During 3421 patient-years, there were 5192 hospital admissions, of which 4252 (82%) were unplanned. We identified five patient subgroups (clusters 1-5) with distinctive hospitalization profiles. HF accounted for approximately one-third of admissions in the first patient cluster (23% of the patient sample). In contrast, patients in the second cluster (39% of the patient sample) were hospitalized for various reasons, with no single prominent admission cause identified. The other three clusters, comprising 16% of the patient sample, accounted for 42% of all unplanned hospitalizations. While patients in the third cluster were hospitalized mainly due to ischemic heart disease and arrhythmia, patients in the fourth and fifth clusters shared a high burden of recurrent HF admissions. The five patient clusters differed by baseline predictors, including age, functional capacity, comorbidity burden, hemoglobin, and cause of HF. HF patients differ significantly in the causes and overall burden of unplanned hospitalizations. The patient subgroups identified and predictors for these subgroups may guide personalized interventions to reduce the burden of unplanned hospitalizations among HF patients.

Post-fault control for three-phase IM drives based on different transformations

ABSTRACT Field-Oriented Control (FOC) strategy is famous for its high accuracy. Nevertheless, the Conventional FOC (CFOC) technique application under the fault is limited. In this research, a novel post-fault control strategy based on the FOC method is developed for wye-connected three-phase Induction Motor (IM) drives under the Open-Phase Fault (OPF). The control system based on the dq model of the faulted wye-connected three-phase IM, where the FOC structure remains unchanged under the OPF, is used in the suggested post-fault control scheme. The proposed control method is derived based on the Conventional Current Transformation (CCT) and an Asymmetrical Voltage Transformation (AVT). The introduced post-fault control strategy in this research does not have difficult implementation and heavy calculation burden. The feasibility of the proposed post-fault control technique has been verified by experimentation. The experimental results are obtained with a three-phase IM with wye connection using a DSP/TMS320F28335 controller showing obviously the effectiveness of the proposed method compared to the conventional controllers during different situations.

Effects of an online mindfulness-based cognitive therapy for caregivers of children with allergic rhinitis.

The incidence of allergic rhinitis in children is high across the world, as well as in China. Allergic rhinitis in children has serious impact on physical and mental health of the children. At the same time, the caregivers of allergic rhinitis children have heavy burden of care, and their mental problems are severe. It is necessary to implement timely psychological intervention for the caregivers of allergic rhinitis children. Mindfulness-Based Cognitive Therapy (MBCT) is a safe and effective psychological therapy, and the effect of online intervention can be comparable to the traditional face-to-face intervention program. This study focused on the mental health status in the main caregivers of children with allergic rhinitis, and conducted a modified online MBCT intervention on the caregivers, in order to improve their adverse mental state, meanwhile, improve the quality of care they provide. The results show that online MBCT intervention is applicable to the main caregivers of children with allergic rhinitis, and can effectively reduce caregiver burden, relieve anxiety and depression, and improve the level of mindfulness in the caregivers.
