ABSTRACT

Moderate physical activity is related to reduced mortality in hemodialysis patients. However, most hemodialysis patients have low physical activity levels for complex reasons. This study investigated the determinants of moderate-to-high physical activity levels and whether psychosocial correlates are associated with engagement in moderate-to-high physical activity among hemodialysis patients. A cross-sectional survey was conducted with 134 hemodialysis outpatients, aged 64.7 years, in three hemodialysis centers in Taiwan. Data on sociodemographics, comorbidities, lifestyles, and psychosocial correlates, including perceived benefits, barriers, and self-efficacy of physical activity, were collected. Multiple logistic regression analyses were performed. Results showed that patients with moderate-to-high physical activity levels constituted a significantly lower proportion of current smokers and had fewer perceived physical activity barriers and higher self-efficacy of physical activity compared with those with low levels. After adjusting for potential sociodemographic covariates, current employment, nonsmoking status, and high self-efficacy of physical activity were significantly associated with moderate-to-high physical activity levels. Developing strategies to improve the self-efficacy of physical activity, support employment, and enhance anti-smoking campaigns in hemodialysis patients can help them engage in moderate-to-high levels of physical activity.

ABSTRACT

AIM: To examine the associations between physical activity patterns, sleep quality, and stress levels among rotating-shift nurses during the COVID-19 pandemic. BACKGROUND: Stress adversely impacts hospital nurses, particularly those on rotating shifts. The effects of physical activity patterns and sleep quality on the stress levels of these nurses during the COVID-19 pandemic warrant investigation. METHODS: A multicenter cross-sectional study was conducted with 550 eligible registered hospital nurses, randomly selected from four hospitals during the COVID-19 pandemic in Taiwan. The work schedule type of these nurses was categorized into rotating shifts (working at least two shifts in a month, involving day, evening, and night shifts) or fixed-day shifts (working only the day shift). Data were collected on sociodemographic characteristics, physical activity patterns (sedentary or active), sleep quality (poor or adequate), and stress levels for analysis. RESULTS: Rotating-shift nurses with active physical activity patterns exhibited lower stress levels compared with those with sedentary patterns. Nurses who experienced adequate sleep quality had lower stress levels compared with those with poor sleep quality among rotating and fixed-day shift nurses. CONCLUSIONS: Active physical activity patterns and adequate sleep quality were associated with lower stress levels among rotating-shift nurses during the pandemic. Promoting active physical activity and enhancing sleep quality are essential strategies for reducing stress in these nurses. IMPLICATIONS FOR NURSING AND HEALTH POLICY: Strategies aimed at promoting physical activity and improving sleep quality should be integral components of health promotion programs and policymaking efforts directed at nursing leaders, to foster a healthy and supportive work environment and enhance the welfare of rotating-shift hospital nurses. REPORTING METHOD: The study is reported using the statement of Strengthening the Reporting of Observational Studies in Epidemiology (STROBE).

ABSTRACT

BACKGROUND: Telerehabilitation has been developed and applied for years for cardiac and pulmonary diseases with good clinical outcomes. However, its application to participants with long COVID remains limited. OBJECTIVES: To investigate the effectiveness of a 12-week telerehabilitation training program in participants with long COVID. The primary outcome was cardiorespiratory fitness (CRF), and secondary outcomes were physical activity (PA) amounts, exercise self-efficacy, sleep quality, and health-related quality of life (HRQOL). METHODS: A parallel-group, randomized controlled trial was conducted. Eligible participants with long COVID (n = 182) were randomly assigned in a 1:1 ratio to either the experimental group (EG) or the control group (CG). The EG received 12 weeks of telerehabilitation training with weekly remote monitoring for exercise maintenance and support. The CG received PA counseling only. CRF, PA amounts, exercise self-efficacy, sleep quality, and HRQOL were assessed at baseline and 12 weeks. Generalized estimating equations were used to analyze the intervention effects by examining the interaction between time and group. RESULTS: One hundred twenty-two participants (67 %) completed the study, and 182 were included in the intention-to-treat analysis. The EG had greater walking behavior (ß = -763.3, p < 0.001), total amount of PA (ß= -711, p = 0.003), exercise self-efficacy (ß = -1.19, p < 0.001), and better sleep quality (ß = 1.69, p = 0.012) after the 12-weeks of telerehabilitation training than the CG. However, there were no significant differences in any CRF parameters or HRQOL at 12 weeks between the EG and CG. CONCLUSION: Telerehabilitation training offers a personalized and convenient approach that can increase exercise willingness and PA amounts and improve sleep quality. These findings underscore the potential benefits of telerehabilitation training for promoting healthier lifestyles and improving overall health outcomes. CLINICAL TRIAL REGISTRATION: The study was registered at ClinicalTrials.gov (NCT05205460) on January 25, 2022.

ABSTRACT

OBJECTIVE: To investigate the association between physical activity (PA) amount and gender differences on cardiorespiratory fitness (CRF), sleep quality, and health-related quality of life (HRQoL) in individuals with long COVID. DESIGN: Cross-sectional study. SETTING: An integrated outpatient clinic for post-COVID-19 at a medical center. PARTICIPANTS: Convenience sample of patients (N=264) diagnosed with long COVID. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: PA amounts, sleep quality, and HRQoL were measured by the International Physical Activity Questionnaire, Pittsburgh Sleep Quality Index, and the World Health Organization Questionnaire on Quality of Life: Short Form, respectively. CRF was evaluated through graded exercise testing. RESULTS: The participants had a mean age of 42.5±13.5 years and a mean duration of post-COVID-19 symptoms of 12.7±6.8 weeks. More than half (n=149, 56.5%) were female patients. Female participants had significantly lower CRF than male participants (P<.05). Older age and higher body mass index were associated with worse CRF and HRQoL (P<.05). Less sitting behavior and greater amounts of vigorous-intensity PA (VPA) or total PA were associated with better CRF (P<.05). In addition, greater total PA and moderate-intensity PA (MPA) were associated with better sleep quality and HRQoL (P<.05), respectively. CONCLUSIONS: Gender differences were found in CRF among patients with long COVID. Greater self-reported VPA or total PA was associated with better CRF, whereas greater total PA and MPA were associated with better sleep quality and HRQoL, respectively, in patients with long COVID. Further research is needed to explore these associations in longitudinal studies.

ABSTRACT

This cross-sectional study investigates the self-reported emotional distress of medical, nursing, dental, pharmacy, and public health students and identifies gender-related differences through an online survey. The data of 364 students were analyzed using Pearson correlation coefficients and multiple logistic regression. Emotional distress was more prevalent among female respondents (11.7 %) than male (3.8 %) respondents. The stigma, isolation, and depression experienced by female respondents influenced their emotional distress, whereas only the depression of male respondents influenced their emotional distress. Our findings suggest that mental health professionals should consider gender-specific factors when developing interventions for the study population to minimize emotional distress.

ABSTRACT

WHAT IS KNOWN ON THE SUBJECT?: People diagnosed with serious mental illness have a high risk of diabetes and are more likely to develop type 2 diabetes at ages below 60 years. Effective diabetes self-care behaviours among people diagnosed with serious mental illness can improve glycaemic control and reduce vascular complications. Few studies have investigated diabetes self-care behaviours and their associations with health literacy and self-efficacy in people diagnosed with serious mental illness. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: Diabetes self-care behaviours in people diagnosed with serious mental illness were suboptimal; the least frequently performed self-care activities were self-monitoring of blood glucose. Factors associated with diabetes self-care behaviours are gender, age, communicative and critical health literacy and self-efficacy. Self-efficacy is the strongest predictor of self-care behaviours among people diagnosed with comorbid serious mental illness and type 2 diabetes. WHAT ARE THE IMPLICATIONS OF PRACTICE?: Mental health nurses should assess diabetes-specific health literacy of people diagnosed with serious mental illness to ensure that they possess the knowledge and skills related to diabetes self-care. When treating young people and those with newly diagnosed type 2 diabetes, nurses should incorporate strategies to minimise their perceptions of diabetes-related distress and increase their confidence in managing comorbid diabetes. ABSTRACT: Introduction People diagnosed with serious mental illness (SMI) experience greater challenges in managing their type 2 diabetes mellitus (T2DM) than do those diagnosed with T2DM alone. Aim This study investigated diabetes self-care activities and the factors associated with these activities in people diagnosed with SMI in a hospital setting. Methods A cross-sectional correlational study was conducted among 126 people diagnosed with comorbid SMI and T2DM in Taipei, Taiwan, between October 2020 and April 2021. Data were collected using self-report questionnaires and a chart review. Three-step hierarchical multiple regression analysis was used to identify factors associated with diabetes self-care behaviours. Results Diabetes self-care behaviours in people diagnosed with SMI were suboptimal overall. Hierarchical multiple regression analyses revealed that age (ß = 0.18, p = .037) and self-efficacy (ß = 0.27, p = .004) significantly associated with diabetes self-care behaviours. Discussion Self-efficacy is the strongest predictor of self-care behaviours among people diagnosed with comorbid SMI and T2DM. Implications for Practice Mental health professionals should focus on enhancing confidence in managing comorbid diabetes in people diagnosed with comorbid SMI, especially young people and those with newly diagnosed T2DM.

ABSTRACT

Reducing the impacts of disasters is imperative in these times when disasters continually threaten people's lives. Given that the readiness for disaster response of nurses are essential in mitigating damage, however, studies on the determinants of nurses' readiness for disaster response remain inconclusive and require further research, especially with various populations. This study therefore aimed to investigate factors associated with readiness for disaster response among Taiwanese hospital nurses. A cross-sectional study was conducted on 365 eligible and registered nurses at a medical centre in northern Taiwan. The Readiness for Disaster Responses Scale including four subscales: personal preparedness, self-protection, emergency response, and clinical management were used for assessment. Analyses were performed using multiple linear regression models. Our study results showed that the length of nursing work was positively associated with nurses' readiness for disaster responses (ß = 0.28, p < .001). Nurses with a master's degree and working in intensive care units or emergency rooms had higher readiness for disaster responses (ß = 0.13, p = .032; ß = 0.14, p = .024) than those with a bachelor's degree and working in other units/specialties (i.e., outpatient department, operating rooms, etc.). Furthermore, nurses with previous disaster training were associated with greater readiness for disaster responses (ß = 0.24, p < .001). This study findings indicate that the identified determinants of hospital nurses' readiness for disaster responses can be taken into consideration in the future recruiting of nurses for deployment to disaster response assistance and the designing of disaster training programmes specifically for nurses.

ABSTRACT

The Physical Health Attitude Scale (PHASe) is an internationally valid and reliable scale for assessing mental health nurses' attitudes toward providing physical health care to people with serious mental illness. This study translated the PHASe into traditional Chinese and evaluated its psychometric properties in the context of Taiwan. A descriptive, cross-sectional study design was adopted, and convenience sampling was used to recruit 520 mental health nurses from 11 hospitals across Taiwan. Data were collected between August and December 2019. Brislin's translation model was used for the validation process. Exploratory factor analysis and confirmatory factor analysis were used to establish the construct validity of the scale, and Cronbach's alpha and composite reliability were used to determine its reliability. The factor analysis results revealed that the 4-factor 17-item traditional Chinese version of the PHASe accounted for 44.2% of the total variance. Each factor had adequate internal consistency (Cronbach's alpha = 0.70 to 0.80). We also noted significant differences between groups with different attitudes, demonstrating known-group validity. Our findings indicate that the traditional Chinese version of the PHASe is acceptable for evaluating nurses' attitudes toward providing physical health care in Taiwan.

ABSTRACT

BACKGROUND: Coordinated control between the bilateral ankle joints plays an important role in performing daily life functions, such as walking and running. However, few studies have explored the impact of stroke on movement disorders that decrease the coordination control of the bilateral extremities and may decrease daily activities that require coordination control of the bilateral ankles. This study aimed to investigate the coordination control of the bilateral ankles using a novel bilateral ankle measurement system and evaluate the relationship of bilateral movement coordination control deficits with motor and functional performances of the lower extremities in patients with stroke. METHODS: Twenty-one healthy adults (36.5 ± 13.2 y/o) and 19 patients with chronic stroke (58.7 ± 10.5 y/o) were enrolled. A novel measurement device with embedded rotary potentiometers was used to evaluate bilateral ankle coordination control. Participants were asked to move their dominant (non-paretic) foot from dorsiflexion to plantarflexion position and non-dominant (paretic) foot from dorsiflexion to plantarflexion position (condition 1) simultaneously, and vice versa (condition 2). Alternating time and angle for coordination control with movements of both ankles were calculated for each condition. Motor and functional performance measurements of the lower extremities included the lower-extremity portion of the Fugl-Meyer assessment (FMA-LE), Berg Balance Test (BBS), Timed Up and Go Test (TUG), and Barthel Index (BI). RESULTS: Compared with the healthy group, alternating time was shorter in the stroke group by 8.3% (p = 0.015), and the alternating angles of conditions 1 and 2 were significantly higher than those of the healthy group by 1.4° (p = 0.001) and 2.5° (p = 0.013), respectively. The alternating angle in condition 2 showed moderate correlations with TUG (r = 0.512; p = 0.025), 10-m walk (r = 0.747; p < 0.001), gait speed (r = - 0.497 to - 0.491; p < 0.05), length (r = - 0.518 to - 0.551; p < 0.05), and BI (r = - 0.457; p = 0.049). CONCLUSION: Stroke decreases alternating time, increases alternating angle, and shows bilateral ankle coordination control deficits temporally and spatially. A higher alternating angle is moderately to highly associated with motor function and lower limb function in patients with stroke.

ABSTRACT

BACKGROUND: Exercise has positive impacts on cardiometabolic health. However, evidence regarding the effectiveness of tele-exercise training on cardiorespiratory fitness and heart rate recovery in patients with cardiometabolic multimorbidity remains limited. AIMS: The aim of this study was to assess whether an assumed increase in physical activity (PA) after a 12-week tele-exercise training program improved cardiorespiratory fitness and heart rate recovery of patients with cardiometabolic multimorbidity. METHODS: A parallel-group randomized controlled trial was conducted. Eligible patients with cardiometabolic multimorbidity (n = 83) were randomized 1:1 to either an experimental group (EG, received a 12-week tele-exercise training program with 3 sessions/week and 30 min/session and weekly remote monitoring for maintenance of exercise) or a control group (CG, usual care only). PA, cardiorespiratory fitness, and heart rate recovery were assessed at baseline and 12 weeks. Generalized estimating equations were used to examine the intervention effects via the interaction of time and group. RESULTS: Sixty-eight participants (81.9%) completed the study, and 83 were included in the intention-to-treat analysis. The EG with higher vigorous-intensity PA (ß = 714, p = .037), walking behavior (ß = 750, p = .0007), and total amount of PA (ß = 1748, p = .001) after the intervention had significantly elevated cardiorespiratory fitness, including VO2peak (ß = 3.9, p = .042), workload (ß = 17.9, p = .034), and anaerobic threshold (ß = 2.1, p = .041), and increased one-min heart rate recovery (ß = 5.3, p = .025), compared with the CG. LINKING EVIDENCE TO ACTION: A 12-week tele-exercise training program was effective for increased PA, elevated cardiorespiratory fitness, and improved heart rate recovery for patients with cardiometabolic multimorbidity. These findings highlight the feasibility of better delivering lifestyle interventions for cardiometabolic health management.

ABSTRACT

The prevalence of chronic diseases (such as diabetes, obesity, cancer, heart disease, and chronic obstructive pulmonary disease) continues to increase among patients with mental illness. This cross-sectional study investigated the factors affecting nurses' views on the provision of physical healthcare to patients with comorbid mental illness and chronic disease. In total, 369 nurses working in mental health were assessed for the physical healthcare attitudes and practices using the Physical Health Attitude Scale for Mental Health Nurses. The results of generalized linear modelling indicated that nurses' involvement in physical healthcare was associated with psychiatric mental health nurse credentials (B = 1.560, 95% CI = 0.292-2.828, P = 0.016) and their confidence in delivering physical healthcare was associated with prior physical healthcare training (B = 0.639, 95% CI = 0.104-1.174, P = 0.019). In addition, the frequency with which the nurses engaged in physical healthcare practices was associated with working in a community unit (B = -7.416, 95% CI = -9.652 to -5.180, P < 0.001), involvement in physical healthcare (B = 0.349, 95% CI = 0.162-0.535, P < 0.001), and confidence in delivering physical healthcare (B = 1.148, 95% CI = 0.776-1.519, P < 0.001). Our findings suggest that interventions aiming to help nurses assess and improve their own physical healthcare practices should consider nurses' background and patients' physical health needs in various settings and focus on cultivating an organizational culture that gives nurses confidence in providing physical healthcare.

ABSTRACT

Pre-frail older adults require appropriate exercise to enhance muscle strength as well as upper limb functionality. We developed a handheld vibrator and evaluated its effectiveness in enhancing muscle strength compared to conventional exercises among pre-frail community-dwelling older adults. Thirty-one pre-frail older adults (aged 75.5 ± 5.1 years) were recruited and randomly allocated to a vibration group (VG) and control group (CG). The VG underwent 20 minutes of vibration (frequency: 30 Hz, amplitude: 5 mm, horizontal vibration) using a handheld vibrator as well as 40 minutes of conventional exercise. The CG received 60 minutes of conventional exercise only. The primary outcome was muscle strength assessment (kg), and the secondary outcome included activities of daily living and instrumental activities of daily living scores. The comparisons between the outcome measures revealed no significant differences at the baseline level. Muscle strength of the dominant (ß = 2.49, p = 0.002) and non-dominant (ß = 1.89, p = 0.02) wrist flexion, brachioradialis (ß = 3.8, p = 0.01), and biceps brachii (ß = 3.02, p = 0.02) in the dominant upper limbs was significantly increased among the VG. The vibration intervention can enhance muscle strength in the upper limbs among pre-frail older adults.

ABSTRACT

Although rotating shifts have a negative health impact, their association with hospital nurses' health risks remains controversial due to incomplete adjustment in lifestyle patterns and heterogeneity of work schedules. However, whether work schedule characteristics are associated with lifestyle patterns and perceived stress remains undetermined. We assessed the correlations of work schedule characteristics, lifestyle patterns, and perceived stress among hospital nurses. This cross-sectional study included 340 nurses from two hospitals. Final data from 329 nurses regarding work schedule characteristics, lifestyle patterns (physical activity, dietary behavior, and sleep pattern), and perceived stress were analyzed via linear regression models. Fixed-day-shift nurses had reduced perceived stress (ß = 0.15, p = 0.007) compared with rotating-shift nurses. Additionally, among rotating-shift nurses, fixed-evening- and fixed-night-shift nurses had longer sleep duration (ß = 0.27, p < 0.001; ß = 0.25, p < 0.001) compared to non-fixed-rotating-shift nurses. Longer rotating-shift work was associated with healthier dietary behaviors (ß = 0.15, p = 0.008), better sleep quality (ß = −0.17, p = 0.003), lower perceived stress (ß = −0.24, p < 0.001), and shorter sleep duration (ß = −0.17, p = 0.003). Hospital nurses' work schedule characteristics were associated with lifestyle patterns, dietary behavior, sleep pattern, and perceived stress. Fixed-shifts were beneficial for lifestyle and lower perceived stress. Longer rotating shifts could help nurses adjust their lifestyles accordingly.

ABSTRACT

BACKGROUND: We aimed to assess and compare kinetics and kinematic variables of bed turning ability using a mobility detection system in patients with and without chronic low back pain and to observe the impacts of the disease on bed turning kinetics and kinematics. METHODS: Thirty-five patients with chronic low back pain were enrolled and compared to healthy controls (n = 34). Pain scores and disability level were assessed by Numeric Pain Rating Scale and the function questionnaires including Oswestry Disability Index and Roland Morris Disability Questionnaire. Bed turning ability was tested using the Mobile Detection System. Univariate and multivariate regression analysis were applied to compare the differences between groups. FINDINGS: Patients with chronic low back pain had significantly lower turning over and back force/weight ratio (p < 0.001) than those healthy controls. Turning over time was significantly longer in patients with Numeric Rating Scale score 3 than in those with Numeric Rating Scale score 2 (p = 0.015). Turning over and back force were significantly higher in male patients and patients with higher BMI after adjusting BMI and sex, respectively (all p < 0.001). When turning back, chronic low back pain patients with Numeric Rating Scale scores of 3 had lower turning back force/weight ratio than those with Numeric Rating Scale scores of 2 (p = 0.014). Male patients had higher turning back force/weight ratio after adjusting pain score (p = 0.001). INTERPRETATION: The novel Mobility Detection System can provide more objective assessments of bed turning kinetics and kinematics in patients with chronic low back pain.

ABSTRACT

We aimed to determine the effect of vibration frequency and direction on upper-limb muscle activation using a handheld vibrator. We recruited 19 healthy participants who were instructed to hold a handheld vibrator in their dominant hand and maintain the elbow at 90° flexion, while vertical and horizontal vibrations were applied with frequencies of 15, 30, 45, and 60 Hz for 60 s each. Surface electromyography (EMG) measured the activities of the flexor digitorum superficialis (FDS), flexor carpi radialis (FCR), extensor carpi ulnaris (ECU), extensor carpi radialis (ECR), biceps, triceps, and deltoid anterior muscles. EMG changes were evaluated as the difference in muscle activity between vibration and no-vibration (0 Hz) conditions. Muscle activity was induced under vibration conditions in both vertical and horizontal (p < 0.05) directions. At 45 Hz, FDS and FCR activities increased during horizontal vibrations, compared with those during vertical vibrations. ECU activity significantly increased under 15-Hz vertical vibrations compared with that during horizontal vibrations. Vibrations from the handheld vibrator significantly induced upper-limb muscle activity. The maximum muscle activations for FDS, ECR, ECU, biceps, and triceps were induced by 45-Hz horizontal vibration. The 60-Hz vertical and 30-Hz horizontal vibrations facilitated maximum muscle activations for the FCR and deltoid anterior, respectively.

ABSTRACT

We developed a new probe, Gd-DO3A-Am-PBA, for imaging tumors. Our results showed active targeting of Gd-DO3A-Am-PBA to sialic acid (SA) moieties, with increased cellular labeling in vitro and enhanced tumor accumulation and retention in vivo, compared to the commercial Gadovist. The effectiveness of our newly synthesized probe lies in its adequate retention phase, which is expected to provide a suitable time window for tumor diagnosis and a faster renal clearance, which will reduce toxicity risks when translated to clinics. Hence, this study can be extended to other tumor types that express SA on their surface. Targeting and MR imaging of any type of tumors can also be achieved by conjugating the newly synthesized contrast agent with specific antibodies. This study thus opens new avenues for drug delivery and tumor diagnosis via imaging.

ABSTRACT

Exercise is fundamentally important in managing chronic diseases and improving health-related quality of life (HRQL). However, whether intradialytic exercise is safe through assessment of changes in dialytic parameters and has a positive impact on HRQL and depression status of hemodialysis patients requires further research with diverse racial and cultural populations to identify. This study aimed to evaluate the effects of intradialytic exercise on dialytic parameters, HRQL, and depression status in hemodialysis patients. A randomized controlled trial was conducted at a medical center in Northern Taiwan. Sixty-four hemodialysis patients were recruited using stratified random sampling. Participants were randomized into an experimental group (EG, n = 32) or a control group (CG, n = 32). The EG received a 12-week intradialytic exercise program while the CG maintained their usual lifestyles. Dialytic parameters, HRQL, and depression status were collected at baseline and at 12 weeks. The results indicated no differences in the dialytic parameters from the baseline between both groups. However, the EG had increased HRQL (ß = 22.6, p < 0.001) and reduced depression status (ß = -7.5, p = 0.02) at 12 weeks compared to the CG. Therefore, a 12-week intradialytic exercise regime is safe and effective in improving HRQL and reducing depression status for hemodialysis patients.

ABSTRACT

A previous study from our group reported that monocyte adhesion to glioblastoma (GBM) promoted tumor growth and invasion activity and increased tumor-associated macrophages (TAMs) proliferation and inflammatory mediator secretion as well. The present study showed that prescribed psychotropic medicine paliperidone reduced GBM growth and immune checkpoint protein programmed death ligand (PD-L)1 expression and increased survival in an intracranial xenograft mouse model. An analysis of the database of patients with glioma showed that the levels of PD-L1 and dopamine receptor D (DRD)2 were higher in the GBM group than in the low grade astrocytoma and non-tumor groups. In addition, GFP expressing GBM (GBM-GFP) cells co-cultured with monocytes-differentiated macrophage enhanced PD-L1 expression in GBM cells. The enhancement of PD-L1 in GBM was antagonized by paliperidone and risperidone as well as DRD2 selective inhibitor L741426. The expression of CD206 (M2 phenotype marker) was observed to be markedly increased in bone marrow-derived macrophages (BMDMs) co-cultured with GBM. Importantly, treatment with paliperidone effectively decreased CD206 and also dramatically increased CD80 (M1 phenotype marker) in BMDMs. We have previously established a PD-L1 GBM-GFP cell line that stably expresses PD-L1. Experiments showed that the expressions of CD206 was increased and CD80 was mildly decreased in the BMDMs co-cultured with PD-L1 GBM-GFP cells. On the other hands, knockdown of DRD2 expression in GBM cells dramatically decreased the expression of CD206 but markedly increased CD80 expressions in BMDMs. The present study suggests that DRD2 may be involved in regulating the PD-L1 expression in GBM and the microenvironment of GBM. Our results provide a valuable therapeutic strategy and indicate that treatments combining DRD2 antagonist paliperidone with standard immunotherapy may be beneficial for GBM treatment.

ABSTRACT

BACKGROUND & PROBLEMS: Early rehabilitation exercise has been shown to reduce the onset of disability in patients following acute stroke. However, the clinical execution rate of early rehabilitation exercise for those patients remains low. Our medical team developed an early rehabilitation care plan for patients with acute stroke in 2013, at which time the execution rate of early rehabilitation exercise for these patients in our hospital was only 37.1%. The survey found that patients and caregivers had insufficient awareness of early rehabilitation exercise; hospital staffs lacked appropriate assistive devices, rehabilitation equipment, nursing guidance tools, and handover records; and new nursing staffs were insufficiently aware of the importance of early rehabilitation exercise. This care plan was developed to improve the execution rate of early rehabilitation exercise in patients with acute stroke to slow the progression of their disability. PURPOSE: The project was designed to improve the knowledge of new nursing staffs regarding early rehabilitation care and the early rehabilitation exercise completion rate of nursing staffs to raise the execution rate of early rehabilitation exercise in patients with acute stroke. RESOLUTION: After completing the cause analysis, multiple strategies were pursued: (1) nursing education sheets with texts, illustrations, video, and posters were used; (2) group in-service educational training was organized; (3) an innovative transfer belt was designed; (4) facilities were set up to deliver virtual-reality (VR) training; (5) standard procedures on early rehabilitation exercise in patients with acute stroke were revised and implemented; (6) nursing handover procedures were revised; and (7) education courses on early rehabilitation exercise for post-stroke patients were developed. RESULTS: The accuracy of knowledge related to early rehabilitation exercise among new nursing staff improved from 31.3% to 80%; the completion rate for nursing education increased from 53.6% to 98%; and the early rehabilitation exercise execution rate increased from 37.1% to 82.8%. CONCLUSIONS: This project successfully increased the motivation and confidence of patients in rehabilitation and the rate of exercise program execution, which may be expected to impact positively on patients' quality of life.

ABSTRACT

The presence of multimorbidity in middle-aged and older adults, which reduces their physical activity and quality of life, is a global health challenge. Exercise is one of the most important health behaviors that individuals can engage in. Previous studies have revealed that aerobic exercise training is beneficial for healthy middle-aged and older adults and those with various chronic diseases, but few studies have designed individualized aerobic exercise training for individuals with multimorbidity. Although individuals with multimorbidity are considerably less adherent to physical activity interventions, telephone-based motivational interviewing may help in strengthening motivation and promoting behavioral change for increasing physical activity and health-related physical fitness. This study aimed to examine whether a 12-week individualized aerobic exercise training in a rehabilitation center combined with telephone-based motivational interviewing is effective in promoting physical activity and health-related physical fitness among middle-aged and older adults with multimorbidity. A randomized controlled trial was conducted. Forty-three participants (aged > 40) were recruited and randomly assigned to the intervention group, comparison group, or control group. The participants' physical activity and health-related physical fitness were assessed at baseline and at 12 weeks. The results indicated that after individualized aerobic exercise training combined with telephone-based motivational interviewing, the participants reported increased total physical activity (Fin = 481.3, p = 0.011), vigorous-intensity physical activity (Fin= 298.9, p = 0.007), dominant and nondominant hand grip (kg) (Fin = 1.96, p = 0.019; Fin = 2.19, p = 0.027, respectively), FEV1/FVC (Fin = 0.045, p = 0.043), VO2 max (ml/kg/min) (Fin = 5.30, p = 0.001), VO2 max predicted (%) (Fin = 21.6, p = 0.001), work (watts) (Fin = 22.5, p = 0.001), and anaerobic threshold (L/min) (Fin = 0.165, p = 0.011). Twelve weeks of individualized aerobic exercise training in the rehabilitation center combined with telephone-based motivational interviewing can increase the total physical activity, vigorous physical activity, and cardiorespiratory fitness of middle-aged and older adults with multimorbidity.
