Relationship between comorbidity and health outcomes in patients with heart failure: a systematic review and meta-analysis.

BACKGROUND: The prevalence of heart failure (HF) is expected to rise due to increased survivorship and life expectancy of patients with acute heart conditions. Patients with HF and other multiple comorbid conditions are likely to have poor health outcomes. This study aimed to assimilate the current body of knowledge and to provide the pooled effect of HF patients' comorbid conditions on health outcomes. METHODS: A systematic search was performed using MEDLINE, EMBASE and CINAHL databases. Observational studies evaluating the relationship between comorbid conditions and the health outcomes of HF were included. The pooled effect sizes of comorbidity on the identified health outcomes were calculated using a random effects model, and the heterogeneity was evaluated using I2 statistics. RESULTS: A total of 42 studies were included in this review, and a meta-analysis was performed using the results of 39 studies. In the pooled analysis, the presence of a comorbid condition showed a significant pooled effect size in relation to the prognostic health outcomes: all-cause mortality (HR 1.31; 95% CI 1.18, 1.45), all-cause readmission (HR 1.16; 95% CI 1.09, 1.23), HF-related readmission (HR 1.13; 95% CI 1.05, 1.23), and non-HF-related readmission (HR 1.17; 95% CI 1.07, 1.27). Also, comorbidity was significantly associated with health-related quality of life and self-care confidence. Furthermore, we identified a total of 32 comorbid conditions from included studies. From these, 16 individual conditions were included in the meta-analyses, and we identified 10 comorbid conditions to have negative effects on overall prognostic outcomes: DM (HR 1.16, 95% CI 1.11, 1.22), COPD (HR 1.31, 95% CI 1.23, 1.39), CKD (HR 1.18, 95% CI 1.14, 1.23, stroke (HR 1.25, 95% CI 1.17, 1.31), IHD (HR 1.17, 95% CI 1.11, 1.23), anemia (HR 1.42, 95% CI 1.14, 1.78), cancer (HR 1.17, 95% CI 1.04, 1.32), atrial fibrillation (HR 1.25, 95% CI 1.01, 1.54), dementia (HR 1.19, 95% CI 1.03, 1.36) and depression (HR 1.17, 95% CI 1.04, 1.31). CONCLUSIONS: Comorbid conditions have significantly negative pooled effects on HF patient health outcomes, especially in regard to the prognostic health outcomes. Clinicians should carefully identify and manage these conditions when implementing HF interventions to improve prognostic outcomes.

Psychometric Evaluation of the Korean Version of Control Attitudes Scale-Revised.

BACKGROUND: Heart failure (HF) is a chronic heart condition that requires patients to adapt to the disease and maintain a high degree of self-management. Patients with HF commonly feel loss of control, which has a negative effect on their compliance to self-care, health-related quality of life, and health outcomes. To promote self-care behavior and to develop healthy coping mechanisms, it is important to understand individual HF patients' perceived control, a self-generated belief that one has the ability to bring forth desired outcomes. Currently, there is no valid and reliable Korean instrument available in measuring perceived control among patients with HF. OBJECTIVE: The objective of this study was to cross-culturally translate, adapt, and evaluate psychometric properties of the Korean version of Control Attitudes Scale-Revised (KCAS-R) in Korean patients with HF. METHODS: The KCAS-R was developed using a translation/back-translation process and an examination of semantic and conceptual equivalence. Reliability was assessed using Cronbach α to determine internal consistency, and item-total and interitem correlations were assessed to test item homogeneity. The construct validity was examined using exploratory factor analysis, confirmatory factor analysis, and testing hypotheses for known associations with self-efficacy, self-care confidence, and self-care. RESULTS: A convenience sample of 138 patients with HF were included for the psychometric testing of an 8-item KCAS-R. The Cronbach α for internal consistency was 0.835, and the item-total correlation was acceptable. The construct validity revealed a 2-factor structure accounting for 63.23% of the total variance. The KCAS-R was associated with higher levels of self-efficacy, self-care confidence, and self-care. In addition, patients with higher perceived control had less depression and anxiety compared with those with lower levels of perceived control. CONCLUSION: This study provided support for the satisfactory reliability and validity of the 8-item KCAS-R in measuring perceived control in Korean patients with HF.

Papaver nudicaule (Iceland poppy) alleviates lipopolysaccharide-induced inflammation through inactivating NF-κB and STAT3.

BACKGROUND: Papaver nudicaule belongs to the Papaveraceae family, which is planted as an annual herbaceous species generally for ornamental purpose. Papaver rhoeas in the same family has been reported to have various pharmacological activities such as antioxidant and analgesic effects. In contrast, little is known about the pharmacological activity of Papaver nudicaule. In this study, the anti-inflammatory activity of Papaver nudicaule extracts and the action mechanisms were investigated in RAW264.7 macrophage cells. METHODS: To investigate the anti-inflammatory activity of five cultivars of Papaver nudicaule with different flower color, samples were collected from their aerial parts at two growth stages (60 and 90 days) and their ethanol extracts were evaluated in the lipopolysaccharide (LPS)-treated RAW264.7 cells by measuring nitric oxide (NO) and prostaglandin E2 (PGE2) levels. Interleukin 1-beta (IL-1ß), Interleukin-6 (IL-6) and Tumor necrosis factor alpha (TNF-α) production were also analyzed by RT-PCR and multiplex assays. Nuclear Factor-kappa-light-chain-enhancer of activated B cells (NF-κB) and Signal transducer and activator of transcription 3 (STAT3) signaling pathways were examined using western blotting and luciferase reporter assays to reveal the action mechanism of Papaver nudicaule extracts in their anti-inflammatory activity. RESULTS: All of the Papaver nudicaule extracts were effective in reducing the LPS-induced NO, which is an important inflammatory mediator, and the extract of Papaver nudicaule with white flower collected at 90 days (NW90) was selected for further experiments because of the best effect on reducing the LPS-induced NO as well as no toxicity. NW90 lowered the LPS-induced PGE2 level and decreased the LPS-induced Nitric oxide synthase 2 (NOS2) and Cyclooxygenase 2 (COX2). In addition, NW90 reduced the LPS-induced inflammatory cytokines, IL-1ß and IL-6. Furthermore, NW90 inhibited the LPS-induced activation of NF-κB and STAT3. CONCLUSIONS: These results indicate that NW90 may restrain inflammation by inhibiting NF-κB and STAT3, suggesting the potential therapeutic properties of Papaver nudicaule against inflammatory disease.

Identification and metabolite profiling of alkaloids in aerial parts of Papaver rhoeas by liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry.

Papaver plants can produce diverse bioactive alkaloids. Papaver rhoeas Linnaeus (common poppy or corn poppy) is an annual flowering medicinal plant used for treating cough, sleep disorder, and as a sedative, pain reliever, and food. It contains various powerful alkaloids like rhoeadine, benzylisoquinoline, and proaporphine. To investigate and identify alkaloids in the aerial parts of P. rhoeas, samples were collected at different growth stages and analyzed using liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry. A liquid chromatography with mass spectrometry method was developed for the identification and metabolite profiling of alkaloids for P. rhoeas by comparing with Papaver somniferum. Eighteen alkaloids involved in benzylisoquinoline alkaloid biosynthesis were used to optimize the liquid chromatography gradient and mass spectrometry conditions. Fifty-five alkaloids, including protoberberine, benzylisoquinoline, aporphine, benzophenanthridine, and rhoeadine-type alkaloids, were identified authentically or tentatively by liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry in samples taken during various growth stages. Rhoeadine alkaloids were observed only in P. rhoeas samples, and codeine and morphine were tentatively identified in P. somniferum. The liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry method can be a powerful tool for the identification of diverse metabolites in the genus Papaver. These results may help understand the biosynthesis of alkaloids in P. rhoeas and evaluate the quality of this plant for possible medicinal applications.

Morusin Induces TRAIL Sensitization by Regulating EGFR and DR5 in Human Glioblastoma Cells.

Glioblastoma is one of the most malignant primary tumors, and the prognosis for glioblastoma patients remains poor. Tumor-necrosis-factor-related apoptosis-inducing ligand (TRAIL) is considered a promising anticancer agent due to its remarkable ability to selectively kill tumor cells. However, since many cancers are resistant to TRAIL, strategies to overcome resistance are required for the successful use of TRAIL in the clinic. In the present study, the potential of morusin as a TRAIL sensitizer in human glioblastoma cells was evaluated. Treatment with TRAIL or morusin alone showed weak cytotoxicity in human glioblastoma cells. However, combination treatment of TRAIL with morusin synergistically decreased cell viability and increased apoptosis compared with single treatment. Morusin induced expression of death receptor 5 (DR5), but not DR4 or decoy receptors (DcR1 and DcR2). Furthermore, morusin significantly decreased anti-apoptotic molecules survivin and XIAP. In addition, morusin reduced expression of EGFR and PDFGR as well as phosphorylation of STAT3, possibly mediating down-regulation of survivin and XIAP. Together these results suggest that morusin enhances TRAIL sensitivity in human glioblastoma cells through regulating expression of DR5 and EGFR. Therefore, the combination treatment of TRAIL and morusin may be a new therapeutic strategy for malignant glioma patients.

Health behaviors of Korean female nursing students in relation to obesity and osteoporosis.

OBJECTIVES: It has been reported that young adults' dietary habits and health behaviors have significant effects on obesity and bone health. However, there is a lack of thorough understanding of the prevalence of unhealthy behaviors and potential relationships to obesity and osteoporosis among young females. METHODS: This cross-sectional study examined dietary habits, health behaviors, anthropometric measurements, and bone mineral density of 160 female nursing students. RESULTS: A relatively large number of students had vitamin D (n = 104, 65%) and calcium (n = 84, 52.5%) deficiencies but displayed excessive cholesterol (n = 86, 53.8%) and sodium (n = 137, 85.6%) intakes. Unhealthy dietary and health habits such as nighttime snacking, coffee drinking, low milk drinking, and lack of exercise were also noted. CONCLUSIONS: Despite their knowledge on health, a large portion of nursing students displayed unhealthy dietary habits and health. Tailored strategies and education to narrow the gap between health behavioral knowledge and practice are urgently needed.

The Influence of Gender Equity in Nursing Education Programs on Nurse Job Satisfaction.

(1) Background: One of the strategies to overcome the shortage of nurses is to minimize gender inequity in nursing culture, starting from the undergraduate education program. Although the number of men entering the nursing profession has increased over the years, the portion of male nurses remains low, particularly in Asian countries. Only a few studies have been conducted to identify gender inequity in nursing, and most of these studies used qualitative study design. Therefore, it is necessary to quantitatively identify gender equity in nursing education and the influence it has on nurse job satisfaction. (2) Methods: A total of 165 male nurses participated in this study. Validated questionnaires were used to assess gender equity in nursing education programs, nurse job satisfaction, nurse job esteem, and nursing professional pride. (3) Results: The mean score of gender equity in nursing programs was 62.6, showing a positive correlation with nurse job satisfaction, nurse job esteem, and nursing professional pride. Gender equity positively predicted nurse job esteem. (4) Conclusions: The gender equity in nursing education programs has positive predictive effects on the factors that influence male nurse job satisfaction. In order to increase nurse job retention, educators should incorporate strategies to minimize gender inequity.

Development and Validation of a Knowledge, Attitudes and Practices Questionnaire on COVID-19 (KAP COVID-19).

Given its highly contagious nature and an absence of a specific antiviral agent to this date, the key to controlling the spread of coronavirus disease 2019 (COVID-19) and decreasing the infection rate is adherence to preventive measures. It is essential to understand an individual's knowledge, attitudes and practices toward COVID-19 since public adherence to health guidelines relies heavily on these aspects. However, there is no validated instrument that evaluates knowledge, attitudes and practices toward COVID-19. Thus, this study aimed to develop and validate such tool. A questionnaire was developed based on international and national guidelines and a review of the literature. Initial items were evaluated by 10 experts to determine content validity. Exploratory factor analysis and reliability testing were conducted with a convenience sample of 229 nursing students. Based on the content, face validity and factor analysis, 34 items were selected. The Kaiser-Meyer-Olkin value of 0.735 indicated a highly acceptable score with a significant Bartlett's test of sphericity (p < 0.0001). The internal consistency coefficients indicated acceptable reliability of the tool (Cronbach's α = 0.75). The KAP COVID-19 is a valid instrument that can be used to evaluate knowledge, attitudes and practices toward COVID-19.

Evaluating the Prevalence and Incidence of Bronchiectasis and Nontuberculous Mycobacteria in South Korea Using the Nationwide Population Data.

Although the prevalence and incidence of bronchiectasis are rising worldwide, basic epidemiologic data have not been reported in Korea. Therefore, this study was conducted to investigate epidemiological characteristics of bronchiectasis and NTM (nontuberculous mycobacteria) pulmonary diseases in Korea using the National Health Insurance Service-National Sample Cohort (NHIS-NSC) data. The relative risks of prevalence and incidence after adjusting for demographic characteristics were evaluated by multivariate Poisson regression. The result of this study showed the prevalence and incidence rates of bronchiectasis and NTM to be epidemiologically similar to each other with a few slight differences, while the prevalence rate of bronchiectasis was not significantly different by gender, and its incidence rate was significantly lower in women than in men. Both the prevalence and incidence of NTM were significantly higher in women than in men. Both the prevalence and incidence rates of bronchiectasis and NTM were significantly lower in the age group below 40-49 years, and significantly higher in the age groups thereafter. As there were gender differences of bronchiectasis and NTM, gender-sensitive risk management should be available. In addition, since both bronchiectasis and NTM increase in prevalence and incidence after the age of 40-49, early detection and intervention strategies targeting the appropriate age group are needed.

Poststroke Sleep Disorders: An Executive Summary.

BACKGROUND: Poststroke sleep disorders (PSSDs) are common manifestations that may lead to adverse outcomes that pose a negative impact on the daily lives of stroke survivors. However, PSSD is poorly understood in terms of etiology, assessment, treatment, and nursing management. The purpose of this executive summary is to provide an overview to broaden our understanding of PSSDs. METHOD: The electronic databases EMBASE, PubMed, CINAHL, Cochrane Library, and Google Scholar were searched to identify any available relevant studies. RESULTS: The 3 main sleep disorders among stroke survivors are sleep apnea, nighttime sleep disturbances, and excessive daytime sleepiness. The PSSD prevalence ranges from 13.2% to 94.0%. CONCLUSION: The causative mechanism seems to be multifactorial, but occurrence may differ depending on the stroke stage. Combined use of subjective and objective assessment methods may increase PSSD detection and early treatment.

Preditores de maus-tratos ao idoso relacionados a idosos e a seus cuidadores primários / Predictores de malos tratos a personas mayores relacionados con las personas mayores y sus cuidadores principales / Predictors for elder mistreatment related to older adults and their primary caregivers

Resumo Objetivos Identificar fatores preditivos de maus-tratos ao idoso relacionados a idosos e seus principais cuidadores e a relação entre formação profissional de saúde e identificação de maus-tratos. Métodos Estudo quantitativo e analítico. Os potenciais fatores de risco para maus-tratos relacionados a 40 idosos e seus cuidadores foram coletados por meio da observação de 12 profissionais de saúde e em uma associação de enfermeiras visitantes. O treinamento de profissionais de saúde na identificação de maus-tratos foi investigado. Estatística descritiva, teste exato de Fisher e análise de regressão linear múltipla foram usados para investigar as relações entre a ocorrência de maus-tratos ao idoso e fatores de risco relacionados ao idoso e ao cuidador, e os fatores preditivos para maus-tratos ao idoso. Resultados A dependência dos idosos em relação aos cuidadores e as condições crônicas de saúde dos cuidadores principais foram preditores de maus-tratos ao idoso. Os fatores de risco apresentados pelos cuidadores primários tendiam a afetar mais os maus-tratos ao idoso do que a dependência dos idosos. O número de treinamentos em maus-tratos ao idoso realizado pelos participantes, seu conhecimento sobre quem é responsável por notificar os maus-tratos ao idoso, o tipo de cuidador principal dos idosos e a condição crônica de saúde dos cuidadores foram os fatores correlacionados que afetaram os maus-tratos ao idoso. Conclusão As descrições de maus-tratos ao idoso das vítimas e perpetradores são difíceis de avaliar; portanto, recomenda-se a triagem mais ampla sob perspectiva dos profissionais de saúde. Futuras pesquisas de enfermagem devem explorar intervenções indiretas, como manipular os fatores de risco que os cuidadores primários representam, a fim de diminuir a ocorrência de maus-tratos ao idoso. Estudos futuros testando modelos de previsão de trajetória dentro de uma amostra maior e mais controlada devem ser conduzidos.

El número de capacitaciones en malos tratos a personas mayores realizado por quienes participaron, sus conocimientos sobre quién es responsable de notificar los malos tratos a personas mayores, el tipo de cuidador principal de personas mayores y la condición crónica de salud de los cuidadores fueron los factores correlacionados que afectaron los malos tratos a personas mayores. Conclusión Las descripciones de malos tratos a personas mayores por parte de las víctimas y perpetradores son difíciles de evaluar; por lo tanto, se recomienda un triaje más amplio bajo la perspectiva de profesionales de la salud. Futuros estudios de enfermería deben investigar intervenciones indirectas, como manipular los factores de riesgo que los cuidadores principales representan, a fin de reducir los casos de malos tratos a personas mayores. Deben realizarse estudios futuros probando modelos de previsión de trayectoria dentro de una muestra más grande y más controlada.

Abstract Objectives To identify predictive factors for elder mistreatment (EM) related to older adults and their primary caregivers and the relationship between healthcare professional training and identification of EM. Methods This was a quantitative and analytic study. Potential risk factors for EM related to 40 older adults and their caregivers were collected through observation by 12 healthcare professionals and in a visiting nurses association. Training of healthcare professionals on EM identification was investigated. Descriptive statistics, Fisher's exact test, and multilevel regression analysis were used to investigate the relationships between the occurrence of EM and older adults and caregiver-related risk factors, and the predictive factors for EM. Results The older adults' dependency on caregivers and primary caregivers' chronic health conditions predicted EM. The risk factors the primary caregivers posed tended to affect EM more than the dependency older adults posed. The number of EM training the participants attended, their knowledge of who is responsible for reporting EM, the type of older adults' primary caregivers, and caregivers' chronic health condition were the correlating factors affecting EM. Conclusion Victims' and perpetrators' descriptions of EM are difficult to gauge; therefore, the broader screening of healthcare professionals' views is recommended. Future nursing research should explore indirect interventions, such as manipulating the risk factors primary caregivers pose, to decrease the occurrence of EM. A subsequent study testing Path prediction models within a bigger and more controlled sample are also warranted.

AEG-1 promotes mesenchymal transition through the activation of Rho GTPases in human glioblastoma cells.

Despite growing evidence indicating that astrocyte elevated gene-1 (AEG-1) plays pivotal roles in tumor progression in various types of human cancers including brain tumors; to date, its role in the regulation of mesenchymal transition is not clear in glioblastoma. In the present study, we investigated the contribution of AEG-1 to stress fiber formation and then the acquisition of mesenchymal characteristics of glioblastoma cells. Gain- and loss-of-function studies in normal immortalized primary human fetal astrocytes (IM-PHFAs) and glioblastoma cells revealed that overexpression of AEG-1 increased expression of mesenchymal markers including N-cadherin and two mesenchymal transition­inducing transcription factors ZEB1 and Slug but decreased epithelial markers E-cadherin and ZO-1. In addition, knockdown of AEG-1 suppressed invasive ability and migration of glioblastoma cells. Overexpression of AEG-1 also induced stress fiber formation and activated the Rho GTPase signaling pathways in glioblastoma cells. Consistently, treatment with an RhoA inhibitor decreased AEG-1-mediated stress fiber formation in glioblastoma cells. Collectively, our findings suggest that AEG-1 promotes mesenchymal transition in glioblastoma through the regulation of the Rho signaling pathway, resulting in tumor invasion, a primary characteristic of malignant brain tumors.

Morusin induces cell death through inactivating STAT3 signaling in prostate cancer cells.

STAT3 has been recognized as an efficacious drug target for prostate cancer because of its constitutive activation in this fatal disease. We recently identified the root bark of Morus alba Linn. as a potential STAT3 inhibitor among 33 phytomedicines traditionally used in Korea. Morusin, an active compound isolated from the root bark of Morus alba, has shown anti-oxidant and anti-inflammatory effects. In the present study, we examined whether morusin has a potential as an anti-cancer agent in prostate cancer. We found that morusin suppressed viability of prostate cancer cells, but little effect in normal human prostate epithelial cells. Morusin also reduced STAT3 activity by inhibiting its phosphorylation, nuclear accumulation, and DNA binding activity. In addition, morusin down-regulated expression of STAT3 target genes encoding Bcl-xL, Bcl-2, Survivin, c-Myc and Cyclin D1, which are involved in regulation of apoptosis and cell cycle. Furthermore, morusin induced apoptosis in human prostate cancer cells by reducing STAT3 activity. Taken together, these results suggest that morusin could be a potentially therapeutic agent for prostate cancer by reducing STAT3 activity and inducing apoptosis.
