BACKGROUND: This study conducted in-depth interviews to explore the factors that influence the adoption of fall detection technology among older adults and their families, providing a valuable evaluation framework for healthcare providers in the field of fall detection, with the ultimate goal of assisting older adults immediately and effectively when falls occur. METHODS: The method employed a qualitative approach, utilizing semi-structured interviews with 30 older adults and 29 families, focusing on their perspectives and expectations of fall detection technology. Purposive sampling ensured representation from older adults with conditions such as Parkinson's, dementia, and stroke. RESULTS: The results reveal key considerations influencing the adoption of fall-detection devices, including health factors, reliance on human care, personal comfort, awareness of market alternatives, attitude towards technology, financial concerns, and expectations for fall detection technology. CONCLUSIONS: This study identifies seven key factors influencing the adoption of fall detection technology among older adults and their families. The conclusion highlights the need to address these factors to encourage adoption, advocating for user-centered, safe, and affordable technology. This research provides valuable insights for the development of fall detection technology, aiming to enhance the safety of older adults and reduce the caregiving burden.

Mediating effect of social support on the relationship between social activity and depressive symptoms among older widows in Taiwan.

The purpose of this study was to investigate the mediating effect of social support on the relationship between social activity and depressive symptoms among older widows in Taiwan. A cross-sectional study was conducted that recruited 256 older widows in southern Taiwan. Data were collected on demographic characteristics, self-rated health, instrumental activities of daily living, social activity, social support, and depression. Multiple linear regressions performed examined whether social activities and social support were significantly associated with depressive symptoms and which types of social activity were significantly related to social support and depressive symptoms. Mediation analyses performed tested the mediation effect of social support between the number of different types of social activities performed (termed "number of activities" in this study) and depression. Overall, 17.2% of the participants reported having at least two depressive symptoms. The total effect of the number of activities on depressive symptoms was significant (p < .001). The direct pathway from the number of activities to depressive symptoms remained significant (p < .001), and the mediation pathway (from the number of activities to depressive symptoms through social support) was also significant (Bootstrap CI = -.072, -.003). These findings demonstrated that older widows had more social support when they participated in more social activities, which could then decrease depressive symptoms. In addition, informal community group activities and religious group activities were the most effective at increasing social support and reducing depressive symptoms among the older Taiwanese widows.

Working Experiences of Care Aides in Long-Term Care Institutions Following the Relaxation of COVID-19 Regulations in Taiwan: A Qualitative Study.

Care aides in long-term care (LTC) institutions care for older disabled residents at high risk for COVID-19. However, they experienced many stressors during the COVID-19 pandemic. This study aims to explore the working experiences of care aides in LTC institutions following the relaxation of COVID-19 regulations in Taiwan. This qualitative descriptive study included 20 care aides who had cared for residents with COVID-19. Data were obtained via semi-structured interviews. Caring for residents with COVID-19 and the difficulties, resources and teamwork, and impact of care aides' work on their lives were discussed. Consequently, four themes were identified. First, difficulties in care, which included physical limitations by protection, workload, and impact of work schedule on the lives of the care aides. Second, psychological impact, such as worry, social isolation, and burnout. Third, interpersonal relationships with supervisors, colleagues, residents, and their families. Fourth, infection control policy from the institution and government. When infection control policies were relaxed, care aides had difficulties in caring for residents; furthermore, their family and social lives were also affected. They were required to learn knowledge of and skills for COVID-19 management. Institutions were required to provide support in materials, care processes, environment, and management.

The trajectory of smoking cessation after treatment and its related factors in Taiwan.

Smoking has multiple negative effects on health; therefore, the Taiwanese government provides smoking cessation clinics to smokers. This study aimed to explore the trajectory of smoking cessation after smokers received treatment and the variables related to different trajectories. A retrospective longitudinal study was conducted, in which 735 adult smokers who received smoking cessation medications were recruited. The participants' demographic characteristics, chronic diseases, smoking characteristics, and cigarette dependence were collected from chart review. The amount of smoking was collected at baseline, and at 1 week, 1 month, 3 months, and 6 months after treatment. The Proc Traj procedure for group-based modeling and multinomial logistic regression were used for statistical analysis. Three trajectories were identified: early quitters (28.03%), late quitters (11.43%) and reducers (60.54%). Compared with early quitters, reducers were younger and had a higher probability of severe cigarette dependence. Compared with early quitters, late quitters had a higher number of taking smoking cessation medications. The findings revealed that approximately 60% of participants who received smoking cessation treatment could not completely quit smoking, and that age, number of medications taken, and cigarette dependence were significant predictors of different trajectories.

Visualization of production and remediation of acetaminophen-induced liver injury by a carboxylesterase-2 enzyme-activatable near-infrared fluorescent probe.

Acetaminophen (APAP) overdose, also known as APAP poisoning, may directly result in hepatic injury, acute liver failure and even death. Nowadays, APAP-induced liver injury (AILI) has become an urgent public health issue in the developing world so the early accurate diagnosis and the revelation of underlying molecular mechanism of AILI are of great significance. As a major detoxifying organ, liver is responsible for metabolizing chemical substances, in which human carboxylesterase-2 (CES2) is present. Hence, we chose CES2 as an effective biomarker for evaluating AILI. By developing a CES2-activatable and water-soluble fluorescent probe PFQ-E with superior affinity (Km = 5.9 µM), great sensitivity (limit of detection = 1.05 ng/mL), near-infrared emission (655 nm) and large Stokes shift (135 nm), activity and distribution of CES2 in cells were determined or imaged effectively. More importantly, the APAP-induced hepatotoxicity and the underlying molecular mechanism of pathogenesis of AILI were investigated by measuring the "light-up" response of PFQ-E towards endogenous CES2 in vivo for the first time. Based on the superior performance of the probe PFQ-E for sensing CES2, we believe that it has broad potential in clinical diagnosis and therapy response evaluation of AILI.

Lower extremity arterial plaque in patients with type 2 diabetes mellitus: A cross-sectional study of 25-(OH)D3 and other risk factors.

OBJECTIVE: The occurrence of chronic vascular complications in individuals with type 2 diabetes mellitus(T2DM) is influenced by multiple factors. This study aims to analyze the correlation between serum 25-(OH)D3 levels and other risk factors with the formation and severity of arterial plaques in the lower extremities, and explore its role in clinical diagnosis and treatment. METHODS: A total of 628 Chinese patients with T2DM were included in this study. Based on the intima-media thickness (IMT) and plaque echogenicity measured by lower extremity vascular ultrasound, the patients were divided into the no plaque group(NP), low-risk plague group(LP), moderate-risk plague group(MP), and severe-risk plague group(SP). Based on 25-(OH)D3 levels, patients were categorized as vitamin D deficient group (VDD，25-(OH)D3 ≤ 20 ng/mL), vitamin D insufficient group (VDI，25-(OH)D3 between>20 ng/mL and < 30 ng/mL), and vitamin D sufficient group (VDS，25-(OH)D3 ≥ 30 ng/mL). The correlation between the severity of lower extremity arterial plaques and serum 25-(OH)D3 levels was analyzed, as well as the risk factors for lower extremity arterial plaque formation in patients with T2DM. RESULTS: The levels of 25-(OH)D3 in patients with arterial plaques were significantly lower than those in the NP (p = 0.002). Additionally, with the increasing severity of lower extremity arterial plaques, 25-(OH)D3 levels also decreased significantly (p = 0.01). The proportion of patients with sufficient 25-(OH)D3 levels was highest in NP, while the proportion of deficient and insufficient groups was higher in LP (p<0.001). Multivariate logistic regression analysis showed that low levels of 25-(OH)D3 were an independent risk factor for lower extremity arterial plaques in T2DM patients. Compared to patients with 25-(OH)D3>20 ng/mL, the odds ratios for the formation of moderate-risk plaques were 2.525 (95 % CI: 1.45-4.39) in patients with 25-(OH)D3 ≤ 20 ng/mL, and 2.893 (95 % CI: 1.59-5.26) for the formation of high-risk plaques. CONCLUSION: Serum 25-(OH)D3 levels may be correlated with the occurrence and severity of lower extremity arterial plaques in patients with T2DM. Low serum 25-(OH)D3 concentration is a risk factor for lower extremity vascular lesions.

Tell me your position: Distantly supervised biomedical entity relation extraction using entity position marker.

A significant amount of textual data has been produced in the biomedical area recently as a result of the advancement of biomedical technologies. Large-scale biomedical data can be automatically obtained with the help of distant supervision. However, the noisy data brought by distant supervision methods makes relation extraction tasks more difficult. Previous work has focused more on how to restore mislabeled relationships, but little attention has been paid to the importance of labeled entity locations for relationship extraction tasks. In this paper, we present a "four-stage" model based on BioBERT and Multi-Instance Learning by using entity position markers. Firstly, the sentence is marked with position. Secondly, BioBERT, a biomedical pre-trained language model, is used in the final sentence feature vector representation not only with the global position marker but also with the start and end marker of both the head and tail entity. Thirdly, the aggregation of sentence vectors in the bag is used as the vector feature of the bag by three aggregation methods, and the performance of different sentence feature vectors combined with different bag encoding methods is discussed. At last, relation classification is performed at the bag level. According to experimental results, the presented model significantly outperforms all baseline models and contributes to noise reduction. In addition, different bag encoding methods need to match corresponding sentence encoding representation to achieve the best performance.

Differences in the healthcare needs of older adults attending primary health centers in urban and rural areas of Taiwan.

PURPOSE: As the older adult population in Taiwan continues to increase, primary health centers (PHCs) play a crucial role in geriatric care. This study explored the differences in the PHC experiences and usage needs of older adults in urban versus rural areas. METHODS: A qualitative study was conducted. Twenty-one older adults were recruited from PHCs in northern, central, southern, and eastern Taiwan. Semistructured interviews were used to collect data, and the interview guidelines included their reasons for visiting PHCs, the health-care services they received, their evaluation of the services, and the advantages and disadvantages of these centers. The data were analyzed using thematic content analysis. RESULTS: The PHC usage needs of older adults in urban areas differ from those of older adults in rural areas in the following 3 aspects: (1) Medical services: older adults in rural areas demand clinics specializing in various medical domains, mobile and home medical care, and case management, whereas those in urban areas demand mobile health examinations. (2) Environment and transportation: older adults in rural areas demand diverse medical equipment, shuttle services, and accessible facilities, whereas those in urban areas demand recreational facilities. (3) Active aging: older adults in rural areas demand health education courses, and those in urban areas demand diverse senior citizen courses as well as opportunities to volunteer and build interpersonal relationships. CONCLUSION: The older adults in urban and rural areas had different PHC usage needs. The older adults in rural areas generally focused on medical care and transportation services in PHCs, whereas those in urban areas generally focused on health promotion as a means of social participation and active aging.

Factors impacting the demonstration of relational autonomy in medical decision-making: A meta-synthesis.

BACKGROUND: Relational autonomy is an alternative concept of autonomy in which an individual is recognized as embedded into society and influenced by relational factors. Social context, including social location, political structure, and social forces, significantly influence an agent to develop and exercise autonomy skills. The relational approach has been applied in clinical practice to identify relational factors impacting patient autonomy and decision-making, yet there is a knowledge gap in how these factors influence the demonstration of relational autonomy in the context of medical decisions of adults. OBJECTIVE: The present study targeted the existing knowledge of what and how relational factors impact individuals making medical decisions using the theoretical framework of relational autonomy. METHODS: A meta-synthesis study was utilized. Four electronic databases, including Embase, OVID Medline, CINAHL, and PubMed, were searched, along with gray literature and reference lists, to identify relevant studies. RESULTS: 23 studies reporting 21 qualitative and two mixed-method studies were reviewed. Four themes emerged from the qualitative findings: (1) supportive relationships facilitate an individual's relational autonomy; (2) obtaining comprehensive information from broader sources helps individuals exercise relational autonomy; (3) undue family pressure impedes the exercising of patient relational autonomy; and (4) healthcare providers' dominant voice hampers the demonstration of relational autonomy. CONCLUSIONS: Applying relational autonomy to assist adults in making well-considered decisions is essential. The meta-synthesis suggests establishing a supportive relationship between individuals, healthcare providers, and family. A supportive relationship will allow healthcare providers to make judgments in line with an individual's values and wishes with the aim of promoting relational autonomy. Advance care planning was proposed as the effective solution to obtain a consensus between individuals and their families while respecting an individual's values and preferences. Furthermore, it is considered crucial for healthcare providers to appreciate an individual's values and incorporate their preferences into recommendations.

Psychosocial and environmental factors related to physical activity in middle-aged and older adults.

The social ecological model provides a comprehensive framework for understanding the multiple-level determinants of physical activity. This study explores the significant individual, social, and environmental variables and their interactions in relation to physical activity in middle-aged and older adults in Taiwan. A cross-sectional study design was implemented. Healthy middle-aged and older adults were recruited (n = 697) through face-to-face and online surveys. The data collected comprised self-efficacy, social support, neighbourhood environment, and demographic characteristics. Hierarchical regression was used for statistical analysis. Self-rated health (B = 74.74, p < .001; B = 101.45, p = .022) and self-efficacy (B = 17.93, p < .001; B = 14.95, p = .020) were the significant individual variables in both middle-aged and older adults. Neighbourhood environment (B = 6.90, p = .015) and the interaction between self-efficacy and neighbourhood environment (B = 1.56, p = .009) were significant in middle-aged adults. Self-efficacy was the most significant predictor for all participants, with the positive correlations of neighbourhood environment arising only for middle-aged adults with high self-efficacy. Policy making or project design should consider multilevel factors in order to facilitate their physical activity.

EEG coherences of the fronto-limbic circuit between patients with major depressive disorder and healthy controls.

BACKGROUND: Imaging studies found that patients with major depressive disorder (MDD) showed abnormal functional connectivity in the fronto-limbic circuit, including the prefrontal cortex (PFC), anterior cingulate cortex (ACC), and limbic system (amygdala). This study used electroencephalography (EEG) coherence as an indicator of functional connectivity in the fronto-limbic circuit and examined the group differences between the MDD group and healthy controls (HC group), and the associations between EEG coherence and depressive symptoms. METHODS: 125 and 132 participants in the MDD and HC groups have measured the symptoms of depression and anxiety, and delta, theta, alpha, and beta1-beta4 EEG coherences in the fronto-limbic circuit and examined the differences between the two groups, and the associations between the EEG coherence and depressive symptoms were examined. RESULTS: Lower theta, alpha, beta1, beta3, and beta4 coherence in the fronto-limbic circuit and higher beta2 coherence between the PFC and limbic system in the MDD group than in the HC group. Negative correlations between delta, theta, beta1, beta3, and beta4 coherence and total depression, cognitive depression, and somatic depression; positive correlations between beta2 coherences in the PFC and limbic system, and total depression and cognitive depression scores in the MDD group. LIMITATIONS: Whether low EEG coherence in the fronto-limbic circuit is applicable to other subtypes of MDD requires further study. CONCLUSIONS: Low EEG coherences in the fronto-limbic circuit were related to depressive symptoms, and increased functional connectivity in the fronto-limbic circuit can be applied by neurofeedback in future studies.

The Significant Predictors for Breast, Cervical, Colorectal, or Oral Cancer Screening Intention and Behavior in Taiwan.

BACKGROUND: Cancer screening can improve outcomes in patients with cancer. Accordingly, under the direction of the National Health Insurance program, the Taiwan government conducts screenings for breast cancer, cervical cancer, oral cancer, and colorectal cancer. OBJECTIVE: The aim of this study was to identify the primary predictors of cancer screening intention and behavior at 1 and 6 months after patients are provided information and an invitation by telephone to attend cancer screenings. METHODS: In this prospective longitudinal study, 339 participants meeting the screening criteria were recruited. At baseline, telephone interviews were used to collect information on demographic characteristics, exercise and smoking habits, family cancer history, screening beliefs, and screening intention. Screening behavior was followed up at 1 and 6 months after the telephone interviews. RESULTS: At baseline, 87.02% of the participants intended to undergo screening, and 31.86% and 63.42% had undergone screening after 1 and 6 months, respectively. The predictors of screening intention were awareness of the screening policy, willingness to learn about screening, and believing in the health benefits of screening. The predictor of screening behavior after 1 month was screening intention at baseline, and the predictors of behavior after 6 months were screening intention, marital status, and belief that cancer is a hereditary disease. CONCLUSION: Adults with screening intention tended to undergo cancer screenings. IMPLICATIONS FOR PRACTICE: The use of strategies based on screening intention, beliefs, and information can be used to improve participation in cancer screening in Taiwan.

Four Sessions of Combining Wearable Devices and Heart Rate Variability (HRV) Biofeedback are Needed to Increase HRV Indices and Decrease Breathing Rates.

Heart rate variability biofeedback (HRVB) is a behavioral intervention that uses resonance frequency breathing to synchronize the heart rate and breathing patterns. This study aimed to explore how many sessions of wearable HRVB devices are needed to increase the HRV index and decrease breathing rates and to compare the HRVB protocol with other psychological intervention programs in HRV indices and breathing rates. Sixty-four participants were randomly assigned to either the HRVB or relaxation training (RT) group. Both groups received interbeat intervals (IBIs) and breathing rates measurement at the pre-training baseline, during training, and post-training baseline from weeks 1 to 4. IBIs were transformed into HRV indices as the index of the autonomic nervous system. The Group × Week interaction effects significantly in HRV indices and breathing rates. The between-group comparison found a significant increase in HRV indices and decreased breathing rates in the HRVB group than in the RT group at week 4. The within-session comparison in the HRVB group revealed significantly increased HRV indices and decreased breathing rates at weeks 3 and 4 than at weeks 1 and 2. There was a significant increase in HRV indices and a decrease in breathing rates at mid- and post-training than pre-training in the HRVB group. Therefore, 4 weeks of HRVB combined with a wearable device are needed in increasing HRV indices and decrease breathing rates compared to the relaxation training. Three weeks of HRVB training are the minimum requirement for increasing HRV indices and reducing breathing rates compared to the first week of HRVB.

Difficulties and countermeasures in implementing age-friendly policies in primary health centers in Taiwan.

BACKGROUND: Taiwan is predicted to become a super-aged society by 2025, and primary health centers (PHCs) are set to play a crucial role in the care of older adults. The Taiwanese government has developed an age-friendly verification framework for PHC. The aims of this study were to explore the difficulties faced by PHC staff in the implementation of age-friendly policies and their solution strategies. METHODS: This study adopted a qualitative research method. The first stage involved conducting five focus groups with the responsible staff of PHCs (n = 41) that have been certified "age-friendly." The focus groups covered the effectiveness, difficulties, and resources of PHCs in regards to the introduction of age-friendly policies. In the second stage, in-depth interviews were conducted with executives of PHCs (n = 5), both certified and not certified as age-friendly, to further compare the difficulties faced by these two types of PHCs, thereby gaining perspectives for solution strategies. The principles of grounded theory were used for data analysis. RESULTS: Four major PHC strategies are employed in the promotion of age-friendliness. First, organizational management, through which managers apply management methods and analyze the present PHC-related health concerns; second, resource utilization, which refers to the tallying, linking, and integrating of resources; third, business operation process, in which work efficiency is improved through the combination of business operations and staff training; finally, hardware improvement, which is achieved through comprehensive cataloging of facility environments. CONCLUSION: The implementation of age-friendliness in PHCs requires the efforts of both the service units and government. With resources provided by the government, PHCs can integrate management methods, businesses operations, and essential resources. Moreover, PHC executives can lead their teams in promoting age-friendly policies, and closely monitor their effectiveness.

Cerebral Venous Oxygen Saturation in Hypoperfusion Regions May Become a New Imaging Indicator to Predict the Clinical Outcome of Stroke.

To automatically and quantitatively evaluate the venous oxygen saturation (SvO2) in cerebral ischemic tissues and explore its value in predicting prognosis. A retrospective study was conducted on 48 AIS patients hospitalized in our hospital from 2015−2018. Based on quantitative susceptibility mapping and perfusion-weighted imaging, this paper measured the cerebral SvO2 in hypoperfusion tissues and its change after intraarterial rt-PA treatment. The cerebral SvO2 in different hypoperfusion regions between the favorable and unfavorable clinical outcome groups was analyzed using an independent t-test. Relationships between cerebral SvO2 and clinical scores were determined using the Pearson correlation coefficient. The receiver operating characteristic process was conducted to evaluate the accuracy of cerebral SvO2 in predicting unfavorable clinical outcomes. Cerebral SvO2 in hypoperfusion (Tmax > 4 and 6 s) was significantly different between the two groups at follow-up (p < 0.05). Cerebral SvO2 and its changes before and after treatment were negatively correlated with clinical scores. The positive predictive value, negative predictive value, accuracy, and area under the curve of the cerebral SvO2 were higher than those predicted by the ischemic core. Therefore, the cerebral SvO2 of hypoperfusion regions was a stronger imaging predictor of unfavorable clinical outcomes after stroke.

Quantitative Distribution of Cerebral Venous Oxygen Saturation and Its Prognostic Value in Patients with Acute Ischemic Stroke.

This study investigated the quantitative distribution of cerebral venous oxygen saturation (SvO2) based on quantitative sensitivity mapping (QSM) and determined its prognostic value in patients with acute ischemic stroke (AIS). A retrospective study was conducted on 39 hospitalized patients. Reconstructed QSM was used to calculate the cerebral SvO2 of each region of interest (ROI) in the ischemic hemisphere. The intraclass correlation coefficient (ICC) and Bland−Altman analysis were conducted to define the best resolution of the distribution map. The correlation between the cerebral SvO2 in hypoxic regions (SvO2ROI < 0.7) and clinical scores was obtained by Spearman and power analysis. The associations between cerebral SvO2 and unfavorable prognosis were analyzed using multivariate logistic regression. Excellent agreement was found between the cerebral SvO2 in hypoxic regions with a resolution of 7.18 × 7.18 × 1.6 mm3 and asymmetrically prominent cortical veins regions (ICC: 0.879 (admission), ICC: 0.906 (discharge)). The cerebral SvO2 was significantly negative with clinical scores (all |r| > 0.3). The cerebral SvO2 and its changes at discharge were significantly associated with an unfavorable prognosis (OR: 0.812 and 0.866). Therefore, the cerebral SvO2 in hypoxic regions measured by the quantitative distribution map can be used as an indicator for evaluating the early prognosis of AIS.

The Associations between Physical Activity, Functional Fitness, and Life Satisfaction among Community-Dwelling Older Adults.

Previous studies showed physical activity had benefits for older adults' life satisfaction, but the mechanism was unclear. This study aimed to investigate whether older adults with more physical activity had better functional fitness and life satisfaction, and whether functional fitness mediated the relationship between physical activity and life satisfaction. A cross-sectional study design was employed, and 623 older adults (73.71 ± 5.91 years) were recruited. Physical activity, functional fitness, life satisfaction, and demographic characteristics were collected. Compared with older adults with low physical activity, those with high (B = 0.41, p = 0.025) and moderate (B = 0.40, p = 0.041) physical activity had better life satisfaction; those with high physical activity had better lower limb muscle strength (B = 1.71, p = 0.001), upper (B = 2.91, p = 0.032) and lower (B = 3.12, p = 0.006) limb flexibility, cardiorespiratory endurance (B = 6.65, p = 0.008), and dynamic balance ability (B = −1.12, p < 0.001). Functional fitness did not mediate the relationship between physical activity and life satisfaction. Promoting physical activity may be useful for increasing older adults' functional fitness and life satisfaction, but the effects on functional fitness only occurred at a high level of physical activity, and the effect of physical activity on life satisfaction was not mediated by functional fitness.

Cardiac Autonomic and Cardiac Vagal Control During and After Depressive and Happiness Autobiographical Memories in Patients With Major Depressive Disorder.

Background: Heart rate variability (HRV) and respiratory sinus arrhythmia (RSA) are indices of cardiac autonomic and cardiac vagal control (CVC), both of which are markers of emotional regulation and physical health. This study examined (1) the differences in cardiac autonomic regulation and CVC during baseline, depressive, and happiness autobiographical memory tasks between participants with major depressive disorder (MDD group) and healthy controls (HC group); (2) the associations between depressive symptoms and cardiac autonomic and CVC; and (3) the reactivity and recovery of cardiac autonomic and CVC between the MDD and HC groups. Methods: A total of 168 and 178 participants were included in the MDD and HC groups, respectively. Demographic data and the Beck Depression Inventory-II were collected before the experimental procedure. Lead II electrocardiograph (ECG) was measured during baseline, depressive, and happiness autobiographical memory tasks, and then interbeat intervals from ECG were converted to the time and frequency domains of HRV and RSA. Results: The participants in the MDD group showed lower HRV (including standard deviation of normal to normal intervals, low frequency, the natural logarithm of low frequency, and the natural logarithm of high frequency) and CVC (RSA and lnRSA) than those in the HC group. Depressive symptoms were positively correlated with heart rate and negatively correlated with the indices of cardiac autonomic and CVC. There was significantly increased reactivity and recovery of cardiac autonomic and CVC during and after depressive and happiness autobiographical memory tasks in the HC group, but not in the MDD group. Discussion: Participants with MDD had cardiac autonomic and CVC dysregulation, decreased reactivity, and did not recover to baseline after emotional provocations. These results can be the theoretical basis for clinical intervention by using HRV biofeedback to restore cardiac autonomic regulation and CVC during and after emotional events in the future.

4-Aminobenzotriazole (ABTA) as a Removable Directing Group for Palladium-Catalyzed Aerobic Oxidative C-H Olefination.

4-Aminobenzotriazole (ABTA) was applied as an effective removable directing group (DG) in Pd-catalyzed C-H activation for the first time. Compared with the widely applied pyridine and quinoline analogs, ABTA showed significantly improved reactivity, achieving aerobic oxidative C-H olefination in excellent yields (up to 95% vs <50% with other reported DGs under identical conditions). Using this new strategy, macrocyclization was achieved to give cyclic peptides in good yields with easy ABTA removal under mild conditions, highlighting the promising potential of this new DG.

The relationships between self-efficacy, self-care ability, and burnout and compassion satisfaction among hospice staff in Taiwan.

OBJECTIVES: Professional quality of life involves the negative and positive effects of proving care to terminal patients on health care professionals, including burnout and compassion satisfaction. Around 18% of hospice staff have experienced burnout, and few studies explore the role of an innate ability to cope with burnout. The aim of this study was to explore the significant predictors of burnout and compassion satisfaction as well as the coping strategies among hospice staff in Taiwan. METHODS: A cross-sectional study was conducted, and 220 hospice staff were recruited. Standardized questionnaires were used to collect self-rated stress and growth due to hospice care, self-efficacy, self-awareness, and managing emotion. RESULTS: Hospice staff who perceived higher stress and lower growth due to hospice care and had lower self-efficacy in providing hospice care experienced higher burnout and lower compassion satisfaction. Those who had a lower level of ability related to self-awareness and managing emotion tended to experience higher burnout. The common coping strategies included seeking social support, taking professional courses for clinical skills, and developing hobbies. CONCLUSION: Hospice staff have to develop professional abilities in regard to hospice care as well as an ability to maintain awareness and manage emotions related to work.
