RESUMEN

Objective: This study aimed to investigate the value of a CT-enhanced scanning radiomics nomogram in distinguishing between early hepatic abscess (EHA) and intrahepatic cholangiocarcinoma (ICC) and to validate its diagnostic efficacy. Materials and Methods: Clinical and imaging data on 112 patients diagnosed with EHA and ICC who underwent double-phase CT-enhanced scanning at our hospital were collected. The contours of the lesions were delineated layer by layer across the three phases of CT scanning and enhancement using 3D Slicer software to define the region of interest (ROI). Subsequently, the contours were merged into 3D models, and radiomics features were extracted using the Radiomics plug-in. The data were randomly divided into training (n = 78) and validation (n = 34) cohorts at a 7:3 ratio, using the R programming language. Standardization was performed using the Z-score method, and LASSO regression was used to select the best λ-value for screening variables, which were then used to establish prediction models. The rad-score was calculated using the best radiomics model, and a joint model was constructed based on the rad-score and clinical scores. A nomogram was developed based on the joint model. The diagnostic efficacy of the models for distinguishing ICC and EHA was assessed using receiver operating characteristic (ROC) curve and area under the curve (AUC) analyses. Calibration curves were used to evaluate the reliability and accuracy of the nomograms, while decision curves and clinical impact curves were utilized to assess their clinical value. Results: Compared with the ICC group, significant differences were observed in clinical data and imaging characteristics in the EHA group, including age, centripetal enhancement, hepatic pericardial depression sign, arterial perfusion abnormality, arterial CT value, and arteriovenous enhancement (p < 0.05). Logistic regression analysis identified centripetal enhancement, hepatic pericardial depression sign, arterial perfusion abnormality, arterial CT value, and arteriovenous enhancement as independent influencing factors. Three, five, and four radiomics features were retained in the scanning, arterial, and venous phases, respectively. Single-phase models were constructed, with the radiomics model from the arterial phase demonstrating the best diagnostic efficacy. The rad-score was calculated using the arterial-phase radiomics model, and nomograms were drawn in conjunction with the clinical model. The nomogram based on the combined model exhibited the highest differential diagnostic efficacy between EHA and ICC (training cohort: AUC of 0.972; validation cohort: AUC of 0.868). The calibration curves indicated good agreement between the predicted and pathological results, while decision curves and clinical impact curves demonstrated higher clinical utility of the nomograms. Conclusion: The CT-enhanced scanning radiomics nomogram demonstrates high clinical value in distinguishing between EHA and ICC, thereby enhancing the accuracy of preoperative diagnosis.

RESUMEN

Osteosarcoma is the most prevalent form of primary malignant bone tumor, primarily affecting children and adolescents. The nerve growth factors (NGF) referred to as neurotrophins have been associated with cancer-induced bone pain; however, the role of NGF in osteosarcoma has yet to be elucidated. In osteosarcoma samples from the Genomic Data Commons data portal, we detected higher levels of NGF and M2 macrophage markers, but not M1 macrophage markers. In cellular experiments, NGF-stimulated osteosarcoma conditional medium was shown to facilitate macrophage polarization from the M0 to the M2 phenotype. NGF also enhanced VCAM-1-dependent monocyte adhesion within the osteosarcoma microenvironment by down-regulating miR-513c-5p levels through the FAK and c-Src cascades. In in vivo xenograft models, the overexpression of NGF was shown to enhance tumor growth, while the oral administration of the TrK inhibitor larotrectinib markedly antagonized NGF-promoted M2 macrophage expression and tumor progression. These results suggest that larotrectinib could potentially be used as a therapeutic agent aimed at mitigating NGF-mediated osteosarcoma progression.

RESUMEN

This prospective crossover study aimed to investigate the effect of binaural beat therapy music on soccer player performance. Between July 2023 and December 2023, 45 athletes (31 females/14 males, mean age = 20.47 ± 0.99) wore Bluetooth earphones through which one of the following was given during initial 20 min warm-up exercises before undergoing repeated sprint ability tests: no music/fast-tempo music/fast-tempo music with background binaural beat therapy music. Heart rate change after warm-up exercises/repeated sprint ability (RSA) tests and the time to finish RSA tests were recorded. Despite no significant difference in heart rate increase after warm-up between the two genders regardless of intervention, larger increases after RSA tests were found in males following any of the three interventions (all p < 0.01) with the most notable difference observed after fast-tempo music (p < 0.0001). A significant effect size (r = 0.2) correlated with fast-tempo music during warm-up in either gender. Binaural beat therapy music during warm-up reached a significant effect size only when all participants were considered, suggesting limited benefits.

RESUMEN

Chondrosarcoma is a malignant bone tumor that emerges from abnormalities in cartilaginous tissue and is related with lung metastases. Nicotinamide phosphoribosyltransferase (NAMPT) is an adipocytokine reported to enhance tumor metastasis. Our results from clinical samples and the Gene Expression Omnibus data set reveal that NAMPT levels are markedly higher in chondrosarcoma patients than in normal individuals. NAMPT stimulation significantly increased lysyl oxidase (LOX) production in chondrosarcoma cells. Additionally, NAMPT increased LOX-dependent cell migration and invasion in chondrosarcoma by suppressing miR-26b-5p generation through the c-Src and Akt signaling pathways. Overexpression of NAMPT promoted chondrosarcoma metastasis to the lung in vivo. Furthermore, knockdown of LOX counteracted NAMPT-facilitated metastasis. Thus, the NAMPT/LOX axis presents a novel target for treating the metastasis of chondrosarcoma.

RESUMEN

Chondrosarcoma is a malignant bone tumor that arises from abnormalities in cartilaginous tissue and is associated with lung metastases. Lymphangiogenesis plays an essential role in cancer metastasis. Visfatin is an adipokine reported to enhance tumor metastasis, but its relationship with VEGF-D generation and lymphangiogenesis in chondrosarcoma remains undetermined. Our results from clinical samples reveal that VEGF-D levels are markedly higher in chondrosarcoma patients than in normal individuals. Visfatin stimulation promotes VEGF-D-dependent lymphatic endothelial cell lymphangiogenesis. We also found that visfatin induces VEGF-D production by activating HIF-1α and reducing miR-2277-3p generation through the Raf/MEK/ERK signaling cascade. Importantly, visfatin controls chondrosarcoma-related lymphangiogenesis in vivo. Therefore, visfatin is a promising target in the treatment of chondrosarcoma lymphangiogenesis.

RESUMEN

BACKGROUND: Many older adults residing in long-term care often face issues like poor sleep, reduced vitality, and depression. Non-pharmacological approaches, specifically Binaural Beat Music (BBM) and Rhythmic Photic Stimulation (RPS), may alleviate these symptoms, yet their efficacy in this demographic has not been extensively explored. AIMS: This study investigated the effects of combined BBM and RPS interventions on sleep quality, vitality, and depression among older residents with depressive symptoms in long-term care facilities. METHODS: Using a quasi-experimental design, a total of 88 older adults with depressive symptoms from Taiwanese daytime care centers were divided into the BBM with RPS, and Sham groups (44 each). They underwent 20-minute daily sessions of their assigned treatment for two weeks. The BBM with RPS group listened to 10 Hz binaural beat music with 10 Hz photic stimulation glasses, and the Sham group received non-stimulating music and glasses. RESULTS: After the intervention, participants in the BBM with RPS groups showed significant improvements in vitality and depressive mood, with a notable increase in sympathetic nervous system activity. Conversely, the Sham group exhibited significant deterioration in vitality and mental health, with a significant increase in parasympathetic activity. Additionally, compared with the Sham group, the BBM and RPS groups showed significant improvements in vitality, mental health, and depression, with a significant increase in sympathetic nervous activity. CONCLUSION: The two-week intervention suggests that the combination of BBM and RPS, as a non-invasive intervention, can potentially improve vitality, mental health, and depressive mood among older adults in long-term care institutions.

RESUMEN

Osteoarthritis (OA) is a low-grade inflammatory joint illness in which monocytes migrate and infiltrate synovial tissue, differentiating into the pro-inflammatory M1 macrophage phenotype. IL-17 is a proinflammatory mediator principally generated by Th17 cells, which is elevated in OA patients; nevertheless, investigators have yet to elucidate the function of IL-17 in M1 polarization during OA development. Our analysis of clinical tissues and results from the open online dataset discovered that the level of M1 macrophage markers is elevated in human OA tissue samples than in normal tissue. High-throughput screening demonstrated that MCP-1 is a potential candidate factor after IL-17 treatment in OA synovial fibroblasts (OASFs). Immunohistochemistry data revealed that the level of MCP-1 is higher in humans and mice with OA than in normal tissues. IL-17 stimulation facilitates MCP-1-dependent macrophage polarization to the M1 phenotype. It also appears that IL-17 enhances MCP-1 synthesis in human OASFs, enhancing monocyte migration via the JAK and STAT3 signaling cascades. Our findings indicate the IL-17/MCP-1 axis as a novel strategy for the remedy of OA.

RESUMEN

OBJECTIVE: This study aimed to examine the effects of binaural beat music (BBM) on sleep quality, heart rate variability, and depression in older people with poor sleep quality in a long-term care institution. METHODS: A single-blind randomized controlled trial design was employed, and 64 older participants with poor sleep quality were recruited from a long-term care institution in Taiwan. Participants were randomized into the BBM group or control group and received 14 days of intervention. During the intervention period, participants in the experimental group listened to 20 min of Taiwanese Hokkien oldies embedded with BBM once in the morning and afternoon three times a week. Participants in the control group only listened to Taiwanese Hokkien oldies. Questionnaires and heart rate variability analysis were used to assess participants' sleep quality, heart rate variability, and depressive symptoms. RESULTS: Significant improvements were observed in sleep quality, along with an increase in heart rate variability means of heart rate and normal sinus beats, and a decrease in low-frequency normalized units and depression severity in the BBM group after the intervention. In the control group, effects on sleep quality were inconsistent, heart rate variability showed significant improvements in some autonomic nervous function regulation, and depression severity was significantly decreased. Furthermore, the BBM group showed a significant improvement in sleep quality and a significant reduction in sympathetic nervous activity compared with the control group. CONCLUSION: This study demonstrates that 14 days of BBM intervention, a non-invasive intervention, could improve sleep quality and depression in older people with poor sleep quality in long-term care institutions.

RESUMEN

OBJECTIVE: This study investigated the impact of a 12-week remote interaction intervention on loneliness, quality of life, and social support for seniors living in a community during the COVID-19 pandemic. METHODS: This study adopted a randomized controlled trial design. Participants in the intervention group received a 12-week bidirectional remote interaction intervention, while participants in the control group received a 12-week unidirectional remote interaction intervention. The study's primary assessment tools were the UCLA Loneliness Scale (UCLA) and the World Health Organization Quality of Life-BREF Scale (WHOQOL-BREF). RESULTS: The main findings indicate that the intervention group scored significantly higher than the control group on the WHOQOL-BREF in the physical health and social relationships domains after the intervention. In addition, intervention group participants with low loneliness scored significantly higher than their control group counterparts in the physical health and social relationships domains of the WHOQOL-BREF. Similarly, intervention group participants with high loneliness scored significantly higher than their control group counterparts in the social relationships domain of the WHOQOL-BREF. However, there was no significant difference in loneliness scores between the intervention and control groups. CONCLUSIONS: This result confirms that providing intensive bidirectional interaction benefits seniors' quality of life during the COVID-19 pandemic.

RESUMEN

Background: The turnover rate of nurse aides in Taiwan is high. However, the predictors of turnover behavior in the newly employed are still unclear. Objective: To examine the predictors of turnover behavior in newly employed licensed nurse aides. Methods: A longitudinal study design was used and subjects were newly employed certified nurse aides from a nurse aid training association in Taiwan. A total of five questionnaire surveys were conducted. The questionnaire was mainly used to collect information on turnover behavior, personal socioeconomic background, workplace psychosocial hazards, worker health hazards, and musculoskeletal disorders. Results: A total of 300 participants were recruited in the study. Cox regression analysis results showed that short working experience (hazard ratio [HR] = 0.21, p < 0.01), work as non-home nurse aides (HR = 0.58, p = 0.01), low monthly salary (HR = 0.68, p < 0.01), high work mental load (HR = 1.01, p = 0.01), low workplace justice (HR = 0.97, p < 0.01), high workplace violence (HR = 1.60, p < 0.01), high burnout (HR = 1.01, p = 0.04), poor mental health (HR = 1.06, p = 0.04), and high total number of musculoskeletal disorder sites (HR = 1.08, p = 0.01) contribute to a higher risk of turnover. Conclusion: The results indicated that employment period, work as a home nurse aide, monthly salary, work mental load, workplace justice, workplace violence, work-related burnout, mental health, and total number of musculoskeletal disorder sites are predictors of turnover behavior in newly employed certified nurse aides.

RESUMEN

BACKGROUND: Meaningful activity participation has shown good predictability for healthy ageing in older adults, and their participation can be assessed using the Meaningful Activity Participation Assessment (MAPA). However, the MAPA has never been validated in any Taiwanese population. Moreover, different cultures may interpret meaningful activity participation differently. This study thus aimed to cross-culturally adapt the MAPA into a Taiwan version (i.e., the T-MAPA) and to investigate the psychometric properties of the T-MAPA in older adults in Taiwan. METHODS: This study consisted of 3 phases. First, the original MAPA was cross-culturally adapted in 6 stages, including forward, synthesis of, and back translations, cognitive debriefing, expert review, and pilot testing on 18 older adults. Second, a Rasch-Andrich rating scale model was applied to evaluate the psychometric properties (including category function, unidimensionality, item functioning and targeting, and reliability) of the adapted version in a sample of 146 older adults. Lastly, the convergent validity and test-retest reliability were examined on 120 and 49 older adults, respectively. RESULTS: After cross-cultural adaptation, the first version of the T-MAPA contained 29 items. Optimal category function was obtained by reducing the response categories of the frequency subscale to 4 and retaining a 5-point rating for the meaningfulness subscale. After the removal of 1 misfit item, a 28-item T-MAPA was generated. This version demonstrated unidimensionality, measurement invariance among different subgroups (regarding sex and education), acceptable item targeting (< 1 logit) and negligible floor and ceiling effects (1.37%; 0.68%), high reliability (person reliability coefficient = 0.86; small standard error < 0.5 with large test information > 4), confirmed convergent validity (absolute r = .49-0.54 with psychological well-being, depressive symptoms, and mental and physical health), and excellent test-retest reliability (intraclass correlation coefficient = 0.94). CONCLUSION: The cross-culturally adapted 28-item T-MAPA is suitable for application to the older population in Taiwan to measure meaningful activity participation. Future examinations of the T-MAPA in other populations with specific clinical features are warranted to extend its utility in practice.

RESUMEN

While vocational training may offer financial and health benefits for patients with schizophrenia (PwS), further empirical research is required to investigate the effectiveness of this intervention for PwS, as well as the factors influencing their employability. This study aimed to (i) identify the factors affecting the employability of PwS who had participated in vocational training and (ii) examine the effectiveness of vocational training. This prospective cohort study was conducted in a community rehabilitation center attached to a psychiatric hospital in southern Taiwan that provides vocational training. The participants completed two questionnaires: (i) a pre-test that served as the study's baseline; (ii) a post-test during a follow-up 12 months later. The questionnaire was divided into three parts: (i) participants' basic information, (ii) the work performance scale, and (iii) the mental state measure. The participants included 35 males and 30 females, with the average age being 45.85 years. The significant factors affecting their employability were social support, work behavior, thinking disorder, and cognitive impairment. In other words, participants with better social support, work behavior, and fewer thought disorders and cognitive impairment were more employable. Their work attitude and ability were found to have significantly improved after having participated in vocational training for 12 months. In conclusion, when conducting vocational training in the future, it is necessary to pay attention to individual participants' social support and work behavior and reduce thinking disorders and cognitive impairments. This may help improve the employability of PwS.

RESUMEN

This study adopted an advanced model, combining the technology acceptance model, the theory of reasoned action, the diffusion of innovations, trust, and five aspects of perceived risk, to measure the factors that influence the behavioral intentions of older adults to use mobile payments. A total of 365 questionnaires were collected from older adults aged 55 years or older from 20 community care sites in central Taiwan. Partial least-squares structural equation modeling was used to test our research model. The results showed that attitude was the main determinant of M-payment in older adults. Moreover, increasing the usefulness, ease of use, and observability of M-payment helped older adults improve their attitudes toward M-payment, thereby increasing their intention to use it. Trust had a significant effect on the usefulness and ease of use of M-payment, while the main factors affecting trust were only performance and financial risks.

RESUMEN

BACKGROUND: The early stage of the COVID-19 pandemic was a critical time for increasing loneliness, especially for older people. However, there is insufficient existing research on associated interventions and their effectiveness. AIM: This study aimed to investigate the effectiveness of an 8-week online interactive course on the loneliness, depression, social support, and quality of life (QOL) of older adults in the community during the COVID-19 pandemic. METHODS: A single-blind randomized controlled trial was conducted to collect data from a community in Taiwan. Eighty-nine participants recruited from long-term care institutions were randomly divided into an experimental group (n = 44) and a control group (n = 45). Participants in the experimental group received an 8-week (Monday to Friday) intensive online interactive course, whereas those in the control group watched 8 weeks (Monday to Friday) of unidirectional online video programs. RESULTS: Significant differences were observed in the UCLA Loneliness Scale and in both the psychological health and social relationship domains of the WHO Quality of Life-BREF Scale. In other words, compared with those in the control group, participants in the experimental group experienced more significant improvements in the state of their loneliness as well as QOL in the psychological health and social relationship domains (without the physical health/environment domains) after taking the online interactive course. CONCLUSIONS: The results of this study showed that the 8-week online interactive course could effectively improve the loneliness, the psychological health domain, and the social relationship domain of the QOL of the older adults of a particular community during the ongoing pandemic.

RESUMEN

BACKGROUND: Elderly homecare service users may reduce their level of social participation and interpersonal interactions due to physiological loss, which may lead to loneliness and depression over the years. However, there is a lack of research on loneliness among older people who use homecare services. The purpose of this study was to examine the factors influencing loneliness among older people using homecare services. METHODS: This is a longitudinal study conducted in communities in Central Taiwan, and data were collected using a structured questionnaire. The questionnaire was first administered as a pre-test to obtain baseline information about the participants, and the same questionnaire was administered as a post-test after 6 months to follow-up. The pre- and post-test questionnaires included five sections, that is, participant demographics, Brief Symptom Rating Scale, Interpersonal Interaction Scale (IIS), Frenchay Activities Index, and UCLA Loneliness Scale (UCLA). RESULTS: A total of 178 participants were recruited in this study. Results indicated that gender, whether participants eat alone or with others at dinner, social media use, perceived economic status, and IIS score were significantly correlated with the loneliness score on the UCLA. Furthermore, there was a significant increase in the loneliness score among male participants in the low loneliness group from baseline to 6 months follow-up. CONCLUSIONS: Gender, presence of others at dinner, social media use, perceived economic status, and interpersonal interaction skills are significant factors that influence loneliness among older people using homecare services. Men tend to experience higher levels of loneliness over time.

RESUMEN

New treatments for chondrosarcoma are extremely important. Chondrosarcoma is a primary malignant bone tumor with a very unfavorable prognosis. High-grade chondrosarcoma has a high potential to metastasize to any organ in the body. Platelet-derived growth factor (PDGF) is a potent angiogenic factor that promotes tumor angiogenesis and metastasis. The adipocytokine visfatin promotes metastatic potential of chondrosarcoma; however, the role of visfatin in angiogenesis in human chondrosarcoma is unclear. We report that the levels of PDGF-C expression were positively correlated with tumor stages, significantly higher than the levels of expression in normal cartilage. Visfatin increased PDGF-C expression and endothelial progenitor cell (EPC) angiogenesis through the PI3K/Akt/mTOR signaling pathway, and dose-dependently down-regulated the synthesis of miR-1264, which targets the 3'-UTR of PDGF-C. Additionally, we discovered inhibition of visfatin or PDGF-C in chondrosarcoma tumors significantly reduced tumor angiogenesis and size. Our results indicate that visfatin inhibits miR-1264 production through the PI3K/Akt/mTOR signaling cascade, and thereby promotes PDGF-C expression and chondrosarcoma angiogenesis. Visfatin may be worth targeting in the treatment of chondrosarcoma angiogenesis.

RESUMEN

College students, particularly female students, often suffer from severe stress and poor sleep. Aromatherapy yoga has become a popular exercise in recent years and may help reduce stress and improve sleep quality, although empirical evidence is limited. We investigated the effectiveness of aromatherapy yoga intervention in reducing stress and improving sleep quality among Chinese female college students. A total of 89 participants-44 in the experimental group (aromatherapy yoga) and 45 in the control group (yoga)-with an average age of 19.88 ± 1.13 years, were enrolled in this quasi-experimental study. Interventions were performed in the respective groups once a week for 12 weeks, for 90 min each time. The Wilcoxon signed-rank test and Mann-Whitney U test (including effect size) were used to test the differences in stress reduction and sleep quality before and after the intervention. From the findings of the current research, both therapies did not help female students' stress levels or sleep hygiene significantly. However, aromatherapy yoga has the potential to improve sleep disturbances experienced by female college students. Additionally, there was no difference in the amount of stress or the quality of sleep between the aromatherapy yoga groups and the regular yoga groups before and after therapy.

RESUMEN

Osteoarthritis (OA) is an age-related disorder that affects the joints and causes functional disability. Hericium erinaceus is a large edible mushroom with several known medicinal functions. However, the therapeutic effects of H. erinaceus in OA are unknown. In this study, data from Sprague-Dawley rats with knee OA induced by anterior cruciate ligament transection (ACLT) indicated that H. erinaceus mycelium improves ACLT-induced weight-bearing asymmetry and minimizes pain. ACLT-induced increases in articular cartilage degradation and bone erosion were significantly reduced by treatment with H. erinaceus mycelium. In addition, H. erinaceus mycelium reduced the synthesis of proinflammatory cytokines interleukin-1ß and tumor necrosis factor-α in OA cartilage and synovium. H. erinaceus mycelium shows promise as a functional food in the treatment of OA.

RESUMEN

BACKGROUND: Team-based learning (TBL) was studied in several preclinical settings, but evidence for its effectiveness in community nursing education is scant. A community health care nursing course was developed, and nursing students engaged in TBL to achieve Sustainable Development Goal 3. PURPOSE: This study aimed to examine the effect of TBL model integration on students' learning attitude, community understanding, and community care competence for achieving SDG 3 and determine the extent to which the TBL model altered students' nursing competence for providing community health care. We compared the effect of TBL and traditional learning (TL) in terms of community health care knowledge objectives. METHODS: TBL was employed as the teaching strategy to guide students' discussion of community care issues, allowing them to fully utilize the knowledge acquired in their community practice. We used an unblinded crossover design, and 99 students participated in the community health nursing course. RESULTS: The results demonstrated that TBL improved participants' community understanding and enhanced their skills for assessing and fulfilling community needs. The experimental and control groups differed significantly in their TBL performance, learning attitude, and nursing competencies. The performance of those who engaged in TBL was higher than that of those who engaged in TL on all community issues. TBL appears to be a more effective method than TL in terms of achieving nursing students' knowledge objectives. CONCLUSIONS: Regarding practical application, the proposed intervention enables nursing students to acquire professional knowledge related to community aging health care and nursing skills, and establish partnerships with community residents. This facilitates the achievement of the United Nations' sustainable development goal of ensuring healthy living and promoting well-being at all ages.

RESUMEN

The purpose of this study is to investigate the correlations that levels of addiction to smartphones, social media, and online games have with levels of real-life and online interpersonal interactions among adolescents. In this cross-sectional study of adolescents in a college in Taiwan, structured questionnaire surveys were used to collect information. The questionnaire included the following: demographic background, Real Interpersonal Interaction Scale (RIIS), Internet Interpersonal Interaction Scale (IIIS), Smartphone Application-Based Addiction Scale (SABAS), Bergen Social Media Addiction Scale (BSMAS), and Internet Gaming Disorder Scale-Short Form (IGDS9-SF). Multiple regression analyses were carried out to investigate the correlations between SABAS, BSMAS, IGDS9-SF, and RIIS/IIIS. We recruited 998 students (413 boys). The average age was 17.18 ± 1.46. The study results show that adolescents with higher levels of addiction to smartphones and social media may have greater interpersonal interaction with friends in real life, but adolescents with high levels of addiction to online games may have less interpersonal interactions with friends in real life. Adolescents with high levels of addiction to smartphones, social media, and online games may have greater interpersonal interactions with friends online.
