RESUMO

OBJECTIVE: The present study aimed to elucidate mechanisms of liothyronine on the treatment of ischemic stroke (IS). METHODS: Differential analysis based on R limma package was used to identify differentially expressed genes, which were then mapped into the connectivity map database for identification of liothyronine associated with IS. Tumor necrosis factor (TNF) signaling pathway was verified through pathway enrichment analysis via Enrichr online. Ischemia stroke mouse model was built up for further analysis. Infarct area and regional cerebral blood flow (rCBF) were measured by 2, 3, 5-triphenyltetrazolium chloride and laser Doppler flowmetry, respectively. Light microscope was used for the evaluation of body weight and dark neurons. Serum TXB2 , 6-Keto-PGF1a , TNF-α, and interleukin-6 (IL-6) levels in mice were measured using enzyme-linked immuno sorbent assay. In addition, relative protein expression levels of brain-derived neurotrophic factor, nestin, and Sox2 were detected by Western blot analysis. RESULTS: Liothyronine with a negative connectivity was identified as one promising treatment for IS through TNF signaling pathway. The experimental results showed that liothyronine treatment significantly meliorated infarct area and the number of dark neurons in IS mice. Liothyronine greatly ameliorated the expression levels of TXB2 and 6-Keto-PGF1a . Besides, rCBF and body weight change of IS mice were increased gradually with increase of drug concentration. Based on pathway enrichment analysis, anti-inflammatory response (TNF-α and IL-6) relevant to TNF signaling pathway was identified, which was further validated in vitro. Furthermore, proteins as neural stem cell markers made a difference with liothyronine treatment. CONCLUSION: Liothyronine may be a novel therapeutic component to exploit an effective medicine for the treatment of IS.

RESUMO

OBJECTIVES: To investigate the utilization of mobility device, whether age and gender-related use disparities exist, and whether falls can further explain use disparities over time among Chinese older adults in need of devices. METHODS: Community-dwelling older adults who needed mobility devices and completed four waves of the China Health and Retirement Survey 2011-2018 were included (N = 1,302). A categorical variable was created to represent respondents' intersectionality of age (50-64, 65-74, and ≥75 years) and gender (men vs. women). RESULTS: The baseline prevalence of device use was 18.2 % (n = 237). Overall, the device use increased over time. Intersectionality-wise, oldest-old women were 1.53 times more likely than youngest-old men to use devices over time. Respondents with falls were more likely to use devices over time. CONCLUSIONS: Older adults with mobility impairment, especially the oldest-old women and those with falls, lag in mobility devices utilization, suggesting future tailored interventions to support these populations.

RESUMO

BACKGROUND: Pain and falls are significant disabling health conditions which cause substantial economic burdens on older adults and their families. Physical functioning (both subjective and objective) might play a significant role in older adults' pain and falls. In this study we aimed to examine: (1) the relationship between pain and falls among Chinese older adults; (2) pain-fall status (i.e., comorbid pain-fall, pain-only, fall-only, and neither-pain-nor-fall) in relation to healthcare utilization; and (3) whether physical functioning measured either subjectively or objectively would contribute differently to the pain intensity and to the occurrence of falls. METHODS: We used a nationally-representative sample of older adults from the 2011-2012 baseline survey of the China Health and Retirement Longitudinal Study (N = 4,461, aged 60-95 years). Logistic, linear, and negative binomial models adjusted for demographic variables were used in the analysis. RESULTS: Overall, 36% of older adults reported pain, 20% had fall occurrences, and 11% had comorbid pain and falls. Pain intensity was significantly associated with falls. Individuals in groups of pain-only, fall-only, and comorbid pain-fall reported significantly higher healthcare utilization, that is, more frequent inpatient care and doctor visits than those in the neither-pain-nor-fall group. Subjective, not objective, physical functioning was associated with pain and falls. CONCLUSION: Pain and falls are significantly associated with each other, and both can lead to increased healthcare utilization. Compared to objective physical functioning, subjective physical functioning is more likely to correlate with pain and falls, suggesting that self-reported physical status should be considered when designing pain-fall preventive strategies.

RESUMO

BACKGROUND: Subjective memory complaints are considered an early sign of cognitive decline. Recent evidence shows that grip strength is an important predictor of cognitive function. However, few studies have compared whether one condition is uniquely associated with cognitive function when another condition is controlled for. AIMS: To explore the longitudinal associations of cognitive function with subjective memory complaints and grip strength in middle-aged and older adults, with a particular focus on whether one condition is uniquely associated with cognitive function when another condition is considered. METHODS: A total of 3,877 middle-aged and older adults (aged 45-92 years) from the China Health and Retirement Longitudinal Study reported on their demographic and health status and completed measures of grip strength and subjective memory complaints, as well as a series of cognitive tests, every two years between 2011 and 2015. Generalized estimating equation models were used to assess the relationships between grip strength, subjective memory complaints, and cognitive function. RESULTS: Grip strength was longitudinally associated with cognitive function (ß = 0.021, 95% confidence interval [CI]: 0.011, 0.030, P < 0.001) independent of subjective memory complaints. In contrast, changes in the subjective memory complaints were not related to cognitive function over time (ß = 0.107, 95% CI: - 0.025, 0.238, P = 0.112). Only at baseline subjective memory complaints were associated with poorer cognitive function (ß = - 1.142, 95% CI: - 1.309, - 0.975, P < 0.001). CONCLUSIONS: Grip strength might be a more important clinical correlate of cognitive function decline over time than subjective memory complaints. DISCUSSION: Regular assessment and close monitoring of grip strength might help identify individuals who might be at high risk for cognitive impairment.

RESUMO

AIMS AND OBJECTIVES: To (1) describe the socio-demographic and behavioural characteristics of older adults who use wearable devices for physical activity monitoring and (2) explore whether wearable device use increases the possibilities of meeting physical activity guideline recommendations among older adults and older adults with known cardiovascular disease or risk. BACKGROUND: Finding ways to increase physical activity and reduce cardiovascular disease risk among older adults is a public health priority. Wearable technology has great potential for promoting physical activity among older adults. DESIGN: A secondary analysis of the national data. METHODS: A nationally representative sample of older adults aged 65 years and older (mean age = 73.79 years, N = 1484) and a subsample of older adults with known cardiovascular disease or cardiovascular disease risk (mean = 74.32 years, N = 1098) was used in the analysis. All analyses were weighted to account for the complex survey design. This study was reported according to the STROBE checklist. RESULTS: The overall prevalence of wearable device use among older adults and older adults with cardiovascular disease risk was 16% and 14%, respectively. Older adults with higher household incomes, better self-rated health, and greater exercise enjoyment were more likely to use wearable devices. Compared with non-users, older adult users were more likely to meet the recommended levels of moderate (55% vs. 31%) and strengthening activity guidelines (46% vs. 25%), but not of the sedentary behaviour guideline (69% vs. 62%). Similar findings were also seen in older adults with known cardiovascular disease or risk. CONCLUSION: The uptake of wearable devices in older adults, particularly those with known cardiovascular disease or risk is still low. The use of wearable devices is an important facilitator of physical activity. It is critical to provide individualised support for their engagement. RELEVANCE TO CLINICAL PRACTICE: Age-friendly design and individualised support are recommended to increase older adults' adoption of wearable devices to improve their physical health. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution was involved in this study since we used publicly available data.

RESUMO

Purpose: To describe cancer survivors' use of electronic communication (e-communication) with clinicians and identify factors associated with their use, including the COVID-19 pandemic. Methods: Secondary analysis included cancer survivors (N = 1,482) from the combined Health Information National Trends Survey HINTS 5 Cycle 3 and Cycle 4. Survivors' use of e-communication was defined by at least one of four e-communication use behaviors in the past 12 months. Bivariate analysis and logistic regression were conducted to examine factors associated with e-communication use. All analyses considered the complex survey design using the jackknife replication method. Results: The prevalence of e-communication use was 64% among cancer survivors. The overall e-communication use slightly increased after the start of the COVID-19 pandemic (63% vs. 64%, p = 0.79). Older adults (≥65 years old) were less likely to use e-communication (odds ratio [OR] = 0.55; 95% confidence interval [CI], 0.36-0.86); survivors who were white (OR = 2.30; 95% CI, 1.36-3.86), living in a metro area (OR = 2.47; 95% CI, 1.44-4.27), diagnosed with breast cancer (OR = 2.03; 95% CI, 1.06-3.88), seeking cancer-related information previously (OR = 2.89; 95% CI, 1.83-4.58), or having a regular health care provider (OR = 2.07,; 95% CI, 1.10-3.88) were more likely to use e-communication. The start of the COVID-19 pandemic was marginally associated with the increased e-communication use (p = 0.053) when other variables were controlled. Conclusion: This nationally representative survey analysis has identified disparities in e-communication use among cancer survivors and revealed the potential increase in e-communication use under the impact of the COVID-19 pandemic. Additional support is clearly warranted for those older, nonwhite, living in rural areas, or without a regular provider, to promote their e-communication use for the delivery of optimal and high-quality cancer care.

RESUMO

BACKGROUND: Falls and depressive symptoms are prevalent and costly. Although they are frequently interrelated, the nature of interrelationships between them was not well understood. Therefore, using longitudinal data, we aimed to explore whether there is a longitudinal bidirectional relationship between falls and depressive symptoms among older Chinese and whether this is different for men and women. METHODS: Older adults aged 60 years+ who completed all 2011, 2013, 2015 waves of data from the China Health and Retirement Longitudinal Study on falls and depressive symptoms were included (N=2,203). Random intercept multilevel models were used to analyze data. RESULTS: Significant bidirectional associations at between-person (b=0.09, SE=0.01, p<0.001) and within-person levels (b=0.05, SE=0.02, p=0.005) were observed between depressive symptoms and falls. When participants reported falls, they reported higher levels of depressive symptoms. However, no gender differs in these relationships. CONCLUSIONS: Regardless of gender, there are significant bidirectional associations between falls and depressive symptoms.

RESUMO

Family caregivers play an important role in coping with older adult falls; however, their perspectives on fear of older adult falling are lacking from the falls prevention literature. A mixed-method design (N=25 dyads) with interview and survey data examined linguistic characteristics and coping strategies used by older adult and family caregiver dyads to manage fear of older adult falling. Fear of older adult falling consisted of both affective (e.g., worry) and cognitive (e.g., cautious) properties. Family caregivers more frequently used affective words and first-person plural pronouns ("we" language) when talking about fear of older adult falling, while older adults more frequently used cognitive and first-and-second person singular pronouns ("I", "you"). The concept of "being careful" was shared within dyads. However, dyad partners differed in their perspectives of what constituted "being careful" and the possibilities of future falling. Findings suggest that the need for family-centered interventions to prevent falls are needed.

RESUMO

BACKGROUND: Due to changes in family policy in China, pregnancy at advanced age (30 years old or above) is prevalent. Advanced maternal age is known to be related to a variety of negative health outcomes, including antenatal depression. Family relationship quality might be an important factor for antenatal depressive symptoms among Chinese women with advanced maternal age. However, the underlying mechanisms in which family relationship quality can affect antenatal depressive symptoms among this population and how positive psychological capital (PsyCap) intervenes in this impact are not clear. OBJECTIVES: To describe the prevalence and demographic characteristics of antenatal depressive symptoms among Chinese pregnant women with advanced maternal age, and to explore the mediation effect of PsyCap in the associations between family relationship quality and antenatal depressive symptoms. METHODS: We conducted a cross-sectional survey at a tertiary hospital in China. A total of 192 women with maternal age of 30 years or older completed the questionnaires. Data on antenatal depressive symptoms, PsyCap, family relationship quality and demographic characteristics were collected. The multiple mediation models in SPSS's PROCESS macro were used to test whether PsyCap mediated the relationship between family relationship quality and antenatal depressive symptoms. RESULTS: Approximately 28.6% of participants had antenatal depressive symptoms and 6.8% reported poor family relationship quality. Participants with higher education (p = .02) and better family relationship quality (p = .00) were less likely to have antenatal depressive symptoms. PsyCap collectively (ß = 1.14, p < .05), or more specifically resilience (ß = 0.61, p < .05) significantly mediated the relationship between poor family relationship quality and antenatal depressive symptoms. DISCUSSION: The relationship between family relationship quality and antenatal depressive symptoms can be mediated by PsyCap collectively or via resilience specifically. It is important to screen antenatal depressive symptoms among pregnant women with advanced age, especially those who have poor family relationship quality. Counseling and psychotherapy initiatives for resilience-enhancing training for pregnant women at advanced age may provide a promising target to break the link between poor family relationship quality and antenatal depressive symptoms.

RESUMO

BACKGROUND: Although there is a general trend of functional decline with age, there lacks an understanding of how cancer diagnosis and other factors may contribute to this trend. This study aimed to examine functional limitation trajectories among adults with and without cancer, and before versus after the cancer diagnosis, and to explore potential contributing factors associated with functional trajectories among cancer survivors. METHODS: The sample were middle-aged and older Chinese adults who participated in all 3 waves of the China Health and Retirement Longitudinal Study (CHARLS, 2011-2015). Ordinary and multiphase growth curve analyses were conducted to examine (1) differences in functional trajectories between participants with (n = 139) and without cancer (n = 7,313), (2) pre-and post-cancer diagnosis changes in functional limitations among those who reported a cancer diagnosis over the 4-year timeframe, and (3) contributing factors associated with functional trajectories among cancer survivors, guided by the Disablement Process Models, including psychological (depressive symptoms), physical (pain and falls), cognitive (self-reported memory problems), and environmental (social contact and available support) factors. RESULTS: There was a trend of increased functional limitations among all participants over time (unstandardized ß = 0.17, p < .0001). However, participants with cancer did not differ from non-cancer participants in neither the level (unstandardized ß = 0.77, p = .08) nor the rate of functional decline (unstandardized ß = -0.43, p = .07). Functional limitation trajectories were different pre- versus post-cancer diagnosis, although not in expected directions (unstandardized ß = -0.48, p < .05). Cancer survivors with greater pain had higher levels of functional limitations which were sustained over time compared to those with less pain (unstandardized ß = 0.93, p < .001). CONCLUSIONS: The study confirmed that Chinese middle-aged and older adults had overall decreased functional decline over time. A novel finding that cancer survivors experienced less rapidly functional decline after the cancer diagnosis suggested that cancer diagnosis might serve as an inflection point at which early intervention is promising to slow the functional decline. In addition, findings that within-person contributing factors, such as pain, can be influential in functional limitation trajectories suggested that more attention is needed to pay to patients with cancer-pain. These findings demonstrated the heterogeneity of functional limitation trajectories and needs for person-centered interventions among Chinese cancer survivors.

RESUMO

BACKGROUND: Electronic communication (e-communication), referring to communication through electronic platforms such as the web, patient portal, or mobile phone, has become increasingly important, as it extends traditional in-person communication with fewer limitations of timing and locations. However, little is known about the current status of patients' use of e-communication with clinicians and whether the use is related to the better patient-perceived quality of care at the population level. OBJECTIVE: The aim of this study was to explore the prevalence of and the factors associated with e-communication use and the association of e-communication use with patient-perceived quality of care by using the nationally representative sample of the 2019 Health Information National Trends Survey 5 (HINTS 5)-Cycle 3. METHODS: Data from 5438 adult responders (mean age 49.04 years, range 18-98 years) were included in this analysis. Multiple logistic and linear regressions were conducted to explore responders' personal characteristics related to their use of e-communication with clinicians in the past 12 months and how their use was related to perceived quality of care. Descriptive analyses for e-communication use according to age groups were also performed. All analyses considered the complex survey design using the jackknife replication method. RESULTS: The overall prevalence of e-communication use was 60.3%, with a significantly lower prevalence in older adults (16.6%) than that in <45-year-old adults (41%) and 45-65-year-old adults (42.4%). All percentages are weighted; therefore, absolute values are not shown. American adults who used e-communication were more likely to be high school graduates (odds ratio [OR] 1.95, 95% CI 1.14-3.34; P=.02), some college degree holders (OR 3.34, 95% CI 1.84-6.05; P<.001), and college graduates or more (OR 4.89, 95% CI 2.67-8.95; P<.001). Further, people who were females (OR 1.47, 95% CI 1.18-1.82; P=.001), with a household income ≥US $50,000 (OR 1.63, 95% CI 1.23-2.16; P=.001), with more comorbidities (OR 1.22, 95% CI 1.07-1.40; P=.004), or having a regular health care provider (OR 2.62, 95% CI 1.98-3.47; P<.001), were more likely to use e-communication. In contrast, those who resided in rural areas (OR 0.61, 95% CI 0.43-0.88; P=.009) were less likely to use e-communication. After controlling for the sociodemographics, the number of comorbidities, and relationship factors (ie, having a regular provider and trusting a doctor), e-communication use was found to be significantly associated with better perceived quality of care (ß=.12, 95% CI 0.02-0.22; P=.02). CONCLUSIONS: This study confirmed the positive association between e-communication use and patient-perceived quality of care and suggested that policy-level attention should be raised to engage the socially disadvantaged (ie, those with lower levels of education and income, without a regular health care provider, and living in rural areas) to maximize e-communication use and to support better patient-perceived quality of care among American adults.

RESUMO

AIM: To explore the mediating role of fear and resilience on the relationship between clinical nurses' reporting of skin lesions and their anxiety and depression during the coronavirus disease 2019 (COVID-19) pandemic. BACKGROUND: Prolonged personal protective equipment wearing may cause severe skin lesions among clinical nurses. The possible relationship between clinical nurses' reporting of skin lesions and their anxiety and depression remains unknown. Moreover, little is known about what factors could mediate such a relationship. METHODS: This is a cross-sectional online survey. CHERRIES was used to report results. RESULTS: Of 2014 participants, 94.8% (n = 1910) reported skin lesions. Skin lesions were positively related to anxiety (p < .001, ß = .228, SE = .099) and depression (p < .001, ß = .187, SE = .093). Fear activated while resilience buffered the relationship between clinical nurses' reporting of skin lesions and anxiety and between skin lesions and depression. CONCLUSION: Reduced fear and enhanced resilience level were related to decreased levels of anxiety and depression among clinical nurses. IMPLICATIONS FOR NURSING MANAGEMENT: Nurse managers should evaluate the occurrence and severity of clinical nurses' skin lesions, arrange reasonable working duration to relieve skin lesions, provide appropriate psychological support to reduce clinical nurses' fear and implement various strategies to enhance their resilience, thereby decreasing their anxiety and depression.

RESUMO

BACKGROUND AND OBJECTIVE: Maintaining physical functioning (i.e. mobility, activities of daily living [ADLs], instrumental activities of daily living [IADLs]) in older adults is essential for independent living. However, little is known about how longitudinal trajectories of physical functioning differ by varying levels of depressive symptoms, subjective memory impairment and cognitive functioning. We aimed to examine whether, and to what degree, the rate of change in physical functioning over time was associated with depressive symptoms, subjective memory and cognitive functioning. DESIGN: A correlational longitudinal design. METHODS: The sample included 5,519 older adults (mean age = 68.13 years) from the China Health and Retirement Longitudinal Study (three waves: 2011-15) who self-reported their depressive symptoms, subjective memory impairment and physical functioning. Cognitive functioning was assessed through interview-based tests. RESULTS: There were significant increases in mobility impairment (ß = 0.27, P < 0.001), ADLs impairment (ß = 0.05, P < 0.001) and IADLs impairment (ß = 0.03, P = 0.006) over time. Compared with the mean score at baseline in 2011, the mobility, ADLs and IADLs impairment increased by 13.32, 10.57 and 4.34% for every 2 years, respectively. Those with high depressive symptoms had accelerated rates of mobility (ß = 0.212, P < 0.001), ADLs (ß = 0.104, P < 0.001) and IADLs impairment (ß = 0.076, P = 0.002). Those with poorer cognitive functioning had more rapid rates of mobility impairment. In contrast, those with differing levels of subjective memory impairment did not experience different physical functioning trajectories. CONCLUSIONS: High depressive symptoms and poor cognitive functioning may be precursors to rapid declines in physical functioning. Proactive screening for these precursors may attenuate physical decline among Chinese older adults.

RESUMO

Data science skills are increasingly needed by informatics nurses and nurse scientists, but techniques such as machine learning can be daunting for those with clinical, rather than computer science or technical, backgrounds. With the increasing quantity of publicly available population-level datasets, identification of factors that predict clinical outcomes is possible using machine learning algorithms. This study demonstrates how to apply a machine learning approach to nursing-relevant questions, specifically an approach to predict falls among community-dwelling older adults, based on data from the 2014 Behavioral Risk Factor Surveillance System. A random forest algorithm, a common approach to machine learning, was compared to a logistic regression model. Explanations of how to interpret the models and their associated performance characteristics are included to serve as a tutorial to readers. Machine learning methods constitute an increasingly important approach for nursing as population-level data are increasingly being made available to the public.

RESUMO

BACKGROUND AND OBJECTIVE: older adults have increased risk of social isolation, loneliness and cognitive functioning impairment, but the relationships among these factors are not conclusive. We investigated the potential mediation mechanism of loneliness on the association between social isolation and cognitive functioning among Chinese older adults within their cultural context. DESIGN: secondary analysis of the baseline wave (2011-12) of the harmonised China Health and Retirement Longitudinal Study. SETTING AND SUBJECTS: community-dwelling older adults in China (N = 7,410 participants aged 60-101 years). METHODS: we applied a multiple indicator multiple cause approach to determine whether the construct of social isolation is well defined by four indicators (social activity engagement, weekly adult children contact, caregiving for grandchildren and living alone) and used structural equation modelling to examine the direct and indirect effects among variables of interest. RESULTS: the results demonstrated that social activity engagement, weekly adult children contact and caregiving for grandchildren were significantly related to social isolation (ß = -0.26 to -0.28) (Living alone was fixed to 1 for model identification.) The indirect effect of social isolation on cognitive functioning through loneliness was significant (ß = -0.15), indicating loneliness was an important mediator. However, the direct effect of social isolation on cognitive functioning also remained significant (ß = -0.83), suggesting a partial mediation effect. CONCLUSIONS: our study highlights the mediation role of loneliness in the relationship between social isolation and cognitive functioning among Chinese older adults. The findings support the beneficial effects of maintaining social relations and coping with feelings of loneliness on older adults' cognitive functioning.

AIMS: (1) Determine the content validity of the Fear of Older Adult Falling Questionnaire-Caregivers using a panel of gerontological experts and a target sample of family caregivers (Stage 1) and (2) Examine the response patterns of the Fear of Older Adult Falling Questionnaire-Caregivers and compare it with older adult version of Fear of Falling Questionnaire Revised using graded-response modelling (Stage 2). DESIGN: Cross-sectional mixed-method design. METHODS: Five content experts and 10 family caregivers were involved in the Stage 1 study and 53 family caregiver-older adult dyads (N = 106) were included in the Stage 2 study. The content-validity index and graded-response modelling were used to analyse data. RESULTS: Among experts, the Fear of Older Adult Falling Questionnaire-Caregivers content-validity index for relevancy, importance, and clarity of individual items and total scale ranged from 0.60-1.00 and from 0.77-0.87, respectively. Among family caregivers, the ratings of the item and scale level content-validity index for relevancy, importance, and clarity ranged from 0.90-1.00 and from 0.95-0.97, respectively. Combining feedback from both groups, we revised one item. Subsequently, the graded-response modelling revealed that a 1-factor, 3-item version of the Fear of Older Adult Falling Questionnaire-Caregivers had acceptable psychometric properties. CONCLUSIONS: The brief 3-item version of the Fear of Older Adult Falling Questionnaire-Caregivers is promising for assessing caregivers' fear of their older adult care recipient falling. IMPACT: A significant concern for family caregivers is fearing that older adult care recipients will fall, but a lack of validated measures limits the study of this phenomena. A 3-item version of the Fear of Older Adult Falling Questionnaire-Caregivers has the potential to identify family caregivers with high fear of older adult falling so that fall risk can be appropriately assessed and addressed.

RESUMO

Falls, which are prevalent among older adults, may not only cause severe physical injuries, but also lead to low fall self-efficacy (FSE). Low FSE is associated with restricted activity, which putatively increases risk of future falls. However, emerging studies have failed to confirm this association. Furthermore, the interplay between age, gender, and fall history with falls has not been adequately addressed in adults aged 70 years or older. The aims of this secondary analysis were to: (1) prospectively explore the association of FSE and fall events considering age, gender, and fall history, and (2) examine the characteristics of fall events and fall-related outcomes. Forty-seven community-dwelling adults over 70 years of age were followed for about 12 months. During the follow-up, 22 participants with low FSE experienced 119 fall events whereas 25 participants with high FSE reported 106 fall events. Among fallers, 72.3% (n = 34) experienced recurrent fall events. About 15.0% (n = 34) of 225 fall events resulted in injuries and 4.0% of injuries required medical care. FSE was a statistically significant predictor of future fall events (incident rate ratio = 0.96, p = .013) regardless of age, gender, and fall history. Participants with low FSE were more likely than those with high FSE to fall more frequently without noticeable prodromal symptoms and apparent reasons. These findings suggest that FSE is an important protective factor against future fall events. However, interpretation of these results requires caution given the small sample size and effect size.

RESUMO

PURPOSE: To examine the influence of parents' screen viewing (SV) duration and self-efficacy in limiting SV on their adolescents' loneliness, and to explore the influence of adolescents' SV duration and self-efficacy in limiting SV on parents' loneliness. DESIGN AND METHODS: A cross-sectional survey with 1573 adolescent-parent dyads from the Family Life, Activity, Sun, Health, and Eating Study were included in this study. The actor-partner interdependence models were used to examine the effect of each dyadic partner's SV duration and self-efficacy in limiting SV on their own and their dyadic partner's loneliness within adolescent-parent dyads. RESULTS: There were no significant actor and partner effects of SV duration on loneliness for both parents and adolescents (all ps > 0.05). Adolescents' self-efficacy in limiting SV was associated with less loneliness of their own (adolescents' actor effect: ß = -0.35, SE = 0.04, p < .01) and that of their parents (adolescents' partner effect: ß = -0.15, SE = 0.04, p = .001). Parents' self-efficacy in limiting SV was negatively associated with their own loneliness (parents' actor effect: ß = -0.25, SE = 0.05, p < .01), but not with their adolescents' loneliness (parents' partner effect: ß = -0.06, SE = 0.05, p = .189). CONCLUSIONS: Adolescents' own self-efficacy in limiting SV has a significant impact on their parents' loneliness. Parents' self-efficacy in limiting SV, however, did not influence their adolescents' loneliness. PRACTICE IMPLICATIONS: Our results highlight the importance of providers screening for loneliness as part of the plan of care for adolescents and parents who might have excessive SV, with close attention given to those who possess less self-efficacy in controlling their SV.

RESUMO

BACKGROUND: Precision health calls for collecting and analyzing large amounts of data to capture an individual's unique behavior, lifestyle, genetics, and environmental context. The diffusion of digital tools has led to a significant growth of patient generated health data (PGHD), defined as health-related data created, gathered or inferred by or from patients and for which the patient controls data collection and data sharing. PURPOSE: We assessed the current evidence of the impact of PGHD use in clinical practice and provide recommendations for the formal integration of PGHD in clinical care. METHODS: We searched PubMed, Ovid, Embase, CINAHL, Web of Science, and Scopus up to May 2018. Inclusion criteria were applied and four reviewers screened titles and abstracts and consequently full articles. FINDINGS: Our systematic literature review identified 21 studies that examined the use of PGHD in clinical settings. Integration of PGHD into electronic records was extremely limited, and decision support capabilities were for the most part basic. DISCUSSION: PGHD and other types of patient-reported data will be part of the health care system narrative and we must continue efforts to understand its impact on health outcomes, costs, and patient satisfaction. Nursing scientists need to lead the process of defining the role of PGHD in the era of precision health.

RESUMO

Health professions trainees' performance in teams is rarely evaluated, but increasingly important as the healthcare delivery systems in which they will practice move towards team-based care. Effective management of care transitions is an important aspect of interprofessional teamwork. This mixed-methods study used a crossover design to randomise health professions trainees to work as individuals and as teams to formulate written care transition plans. Experienced external raters assessed the quality of the written care transition plans as well as both the quality of team process and overall team performance. Written care transition plan quality did not vary between individuals and teams (21.8 vs. 24.4, respectively, p = 0.42). The quality of team process did not correlate with the quality of the team-generated written care transition plans (r = -0.172, p = 0.659). However, there was a significant correlation between the quality of team process and overall team performance (r = 0.692, p = 0.039). Teams with highly engaged recorders, performing an internal team debrief, had higher-quality care transition plans. These results suggest that high-quality interprofessional care transition plans may require advance instruction as well as teamwork in finalising the plan.
