Exploring the characteristics and antecedents of clinically significant long COVID: A longitudinal cohort study.

BACKGROUND: A significant number of coronavirus disease 2019 (COVID-19) survivors are experiencing long COVID, with symptoms lasting beyond three months. While diverse long COVID symptoms are established, there are gaps in understanding its long-term trends, intensity, and risk factors, requiring further investigation. AIMS: This study aimed to investigate the long COVID characteristics and associated factors by following COVID-19 survivors for one year post-infection and comparing them with healthy counterparts. MAIN METHODS: In this longitudinal, correlational study, COVID-19 survivors diagnosed between November 2021 and February 2023 were monitored every three months for a year. Participants aged ≥18 years who had reported a positive COVID-19 test were recruited via social media and healthcare provider referrals. KEY FINDINGS: Out of 182 survivors who initially agreed to participate, 176 completed the study. The mean age was 47.56 years (SD = 16.2), and 51.1 % were female. There was a clinically significant decline in cognitive function and health-related quality of life over time, with symptoms like shortness of breath, reduced physical fitness, and increased health concerns. Those with severe acute COVID-19 symptoms experienced greater cognitive and physical declines and more shortness of breath a year later. Lower financial status was linked to poorer health-related quality of life and increased health concerns. SIGNIFICANCE: A year post-infection, COVID-19's impact on cognitive function and health-related quality of life remains significant, affecting individuals and communities. Survivors with severe initial symptoms and economic disadvantages need more attention. Future research should identify additional predictors of severe long COVID.

Nurses' knowledge of and attitude toward postoperative patient-controlled analgesia (PCA) and the associated factors.

BACKGROUND: Postoperative pain control is pivotal for surgical care; it facilitates patient recovery. Although patient-controlled analgesia (PCA) has been available for decades, inadequate pain control remains. Nurses' knowledge of and attitude toward PCA may influence the efficacy on clinic application. PURPOSE: The purpose of this study is to evaluate nurses' knowledge of and attitude toward postoperative PCA and investigate the associated factors. METHODS: This is a cross-sectional study. We enrolled registered nurses from a 2200-bed medical center in northern Taiwan within one year. The participants completed an anonymous self-reported PCA knowledge inventory and PCA attitude inventory. Data were analyzed descriptively and associated were tested using logistic regression. RESULTS: With 303 participants enrolled, we discovered that nurses had limited knowledge of and a negative attitude toward PCA. Under half of the participants know how to set up a bolus dose and lockout intervals. The majority held misconceptions regarding side effect management for opioids. The minority agree to increase the dose when a patient experienced persistent pain or suggested the use of PCA. Surprisingly, participants with a bachelor's or master's degree had lower knowledge scores than those with a junior college degree. Those with 6-10 years of work experience also are lower than those with under 5 years of experience. However, the participants with experience of using PCA for patient care had higher knowledge scores and a more positive attitude. CONCLUSIONS: Although postoperative PCA has been available for decades and education programs are routinely provided, nurses had limited knowledge of and a negative attitude toward PCA. A higher education level and longer work experience were not associated with more knowledge. The current education programs on PCA should be revised to enhance their efficacy in delivering up-to-date knowledge and situation training which may convey supportive attitude toward clinical application of PCA.

Factors Associated With Levels of Public Engagement in Protective Behaviors During the Early COVID-19 Pandemic: Causal-Comparative Study Based on the Health Belief Model.

BACKGROUND: While the challenges of COVID-19 are still unfolding, the enhancement of protective behavior remains a top priority in global health care. However, current behavior-promoting strategies may be inefficient without first identifying the individuals with lower engagement in protective behavior and the associating factors. OBJECTIVE: This study aimed to identify individuals with and potential contributing factors to low engagement in protective behavior during the COVID-19 pandemic. METHODS: This is a causal-comparative study. A theory-based web-based survey was used to investigate individuals' protective behavior and potential associating factors. During June 2020, the distribution of the survey was targeted to 3 areas: Taiwan, Japan, and North America. Based on the theory of the health belief model (HBM), the survey collected participants' various perceptions toward COVID-19 and a collection of protective behaviors. In addition to the descriptive analysis, cluster analysis, ANOVA, and Fisher exact and chi-square tests were used. RESULTS: A total of 384 responses were analyzed. More than half of the respondents lived in Taiwan, followed by Japan, then North America. The respondents were grouped into 3 clusters according to their engagement level in all protective behaviors. These 3 clusters were significantly different from each other in terms of the participants' sex, residency, perceived barriers, self-efficacy, and cues of action. CONCLUSIONS: This study used an HBM-based questionnaire to assess protective behaviors against COVID-19 and the associated factors across multiple countries. The findings indicate significant differences in various HBM concepts among individuals with varying levels of behavioral engagement.

Pediatric palliative care utilization by decedent children: A nationwide population-based study, 2002-2017.

PURPOSE: This study aimed (1) to describe how trends in pediatric palliative care (PPC) utilization changed from 2002 to 2017, and (2) to examine factors predicting PPC utilization among decedent children in Taiwan. DESIGN: This retrospective, correlational study retrieved 2002-2017 data from three national claims databases in Taiwan. METHODS: Children aged 1 through 18 years who died between January 2002 and December 2017 were included. Pediatric palliative care utilization was defined as PPC enrollment and PPC duration, with enrollment described by frequency (n) and percentage (%) and duration described by mean and standard deviation (SD). Logistic regression was used to examine the associations of various demographic characteristics with PPC enrollment; generalized linear regression was used to examine associations of the demographic characteristics with PPC duration. FINDINGS: Across the 16-year study period, PPC enrollment increased sharply (15.49 times), while PPC duration decreased smoothly (by 29.41%). Cause of death was a continuous predictor of both PPC enrollment and PPC duration. The children less likely to be enrolled in PPC services were those aged 1 to 6 years, boys, living in poverty, living in rural areas, and diagnosed with life-threatening noncancer diseases. CONCLUSION: This study used nationwide databases to investigate PPC enrollment and PPC duration among a large sample of deceased children from 2002 to 2017. The findings not only delineate trends and predictors of PPC enrollment and PPC duration but also highlight great progress in PPC as well as the areas still understudied and underserved. This information could help the pediatric healthcare system achieve the core value of family-centered care for children with life-threatening diseases and their families. CLINICAL RELEVANCE: Pediatric palliative care should be widely and continuously implemented in routine pediatric clinical practice to enhance quality of life for children and their families at the end of life.

Examining the Role of Resilience, Posttraumatic Growth, and Quality of Life in Women with Breast Cancer: A Serial Multiple Mediator Model Approach.

OBJECTIVES: It is unclear how resilience and posttraumatic growth help women with breast cancer face cancer-related symptom distress. This study included both resilience and posttraumatic growth as mediators in a serial multiple mediator model to examine changes in the relationship between symptom distress and quality of life among women with breast cancer. DATA SOURCES: We conducted the descriptive, cross-sectional study in Taiwan. Data were collected using a survey that assessed symptom distress, resilience, posttraumatic growth, and quality of life. A serial multiple mediator model examined one direct and three specific indirect effects of symptom distress on quality of life through resilience and posttraumatic growth. All 91 participants reported the presence of symptom distress and moderate levels of resilience. Quality of life was significantly associated with symptom distress (b = -1.04), resilience (b = 0.18), and posttraumatic growth (b = 0.09). The indirect effect of symptom distress on quality of life through resilience alone was statistically significant (b = -0.23, 95% CI -0.44 to -0.07) and statistically greater than the specific indirect effect through resilience and posttraumatic growth combined (b = -0.21, 95% CI -0.40 to -0.05). CONCLUSION: Resilience plays a unique role in reducing the impact of symptom distress on the quality of life among women with breast cancer. IMPLICATIONS FOR NURSING PRACTICE: Given the importance of resilience to quality of life, oncology nurses can assess the resilience of women with breast cancer and help identify available internal, external, and existential resources to strengthen their resilience.

Scale Validation of the Mandarin-Language Supportive Care Needs Survey-Adolescent Form.

OBJECTIVES: To (1) modify the Mandarin-language 34-item Supportive Care Needs Survey-Adult Form into the Adolescent Form and (2) examine the psychometric properties of the Adolescent Form. DATA SOURCES: A multiphase, iterative scale validation process was used in this methodological study. Participants who were 13 to 18 years old and receiving cancer treatment in inpatient or outpatient settings, or receiving follow-up care in outpatient settings, were recruited using a convenience sampling method. Confirmatory factor analysis demonstrated good fitness of indices, and all factor loadings for the 18-item Adolescent Form were >0.50, which supported the scale's construct validity. The Adolescent Form score was significantly correlated with the symptom distress score (r = 0.56, P < .01) and quality of life score (r = -0.65, P < .01), which indicated the scale's convergent validity. The correlated item-total correlations (0.30-0.78), Cronbach's alpha (.93), and test-retest reliability coefficient (0.79) confirmed the scale's stability. CONCLUSION: This study successfully modified the 34-item Adult Form into the 18-item Adolescent Form. Given its adequate psychometric properties, this concise scale has great promise as a useful, feasible, and age-appropriate tool for evaluating care needs among adolescents with cancer who speak Mandarin. IMPLICATIONS FOR NURSING PRACTICE: This scale can screen for unmet care needs in busy pediatric oncology settings or large-scale clinical trials. It allows for cross-sectional comparison of unmet care needs between adolescent and adult populations and for longitudinal follow-up into how unmet care needs change from adolescence into adulthood.

Medical clowning influences the emotions of parents of children undergoing cancer treatment: A quasi-experimental study.

BACKGROUND: Medical clowning for children has been found to be effective at enhancing parents' psychological well-being during preoperative preparation, but has not been found during cancer treatment. This study aimed to examine whether and how medical clowning influenced the emotions of parents of children undergoing cancer treatment. METHODS: In this quasi-experimental study, 96 parents of children receiving inpatient cancer treatment were recruited, from June 2018 through April 2020. A demographic questionnaire measuring characteristics of parent and dyadic child, Brief Symptom Rating Scale measuring psychological distress of the parent, and Mood Assessment Scale measuring emotional status of parent and child were administered 1 day before a clowning service. The day after the clowning service, the Mood Assessment Scale again collected emotional status for parent and child. Descriptive analysis, bivariate analysis, and structural equation modeling to fit the actor-partner, cross-lagged model were used. FINDINGS: Parents experienced a low degree of psychological distress that called for emotional management. The indirect effect of medical clowning on parents' emotions through children's emotions was significant, as were the direct effect and total effect of medical clowning on parents' emotions. DISCUSSION: Parents experienced psychological distress during their child's inpatient cancer treatment. Medical clowning can directly improve children's emotions and through this pathway indirectly improve their parents' emotions. APPLICATION TO PRACTICE: There is need to monitor psychological distress and provide interventions for parents of children undergoing cancer treatment. Medical clowns should continue to serve parent-child dyads in pediatric oncology practice and become members of multidisciplinary health care teams.

The impacts of the scope of benefits expansion on hospice care among adult decedents: a nationwide longitudinal observational study.

OBJECTIVES: Compared to aggressive treatment for patients at the end stage of life, hospice care might be more likely to satisfy such patients' need and benefits and improve their dignity and quality of life. Whether the reimbursement policy expansion affect the use of hospice care among various demographics characteristics and health status was unknown. Therefore, the purpose of this study was to explore the impacts of reimbursement policy expansion on hospice care use, and to investigate the effects on people with various demographics characteristics and health status. METHODS: We used the 2001-2017 Taiwan NHI claims data, Death Registry, and Cancer Registry in this study, and we included people who died between 2002 and 2017. The study period was divided into 4 sub-periods. hospice care use and the initiation time of 1st hospice care use were used as dependent variables; demographic characteristics and health status were also collected. RESULTS: There were 2,445,781 people who died in Taiwan during the study period. The results show that the trend of hospice care use increased over time, going steeply upward after the scope of benefits expansion, but the initiation time of 1st hospice care use did not increase after the scope of benefits expansion. The results also show that the effects of expansion varied among patients by demographic characteristics. CONCLUSION: The scope of benefits expansion might induce people's needs in hospice care, but the effects varied by demographic characteristics. Understanding the reasons for the variations in all populations would be the next step for Taiwan's health authorities.

The Moderated Mediating Effects of Nutrition and Physical Activity Between Fatigue and Quality of Life in Childhood Cancer Survivors.

PURPOSE: The aim of this study was to investigate the associations between nutrition, physical activity, fatigue, and quality of life (QoL) among childhood cancer survivors. The specific purpose was to examine whether nutrition mediated and physical activity moderated the relationship between fatigue and QoL in this population. METHODS: A pooled sample of 120 childhood cancer survivors was recruited at pediatric oncology wards and ambulatory settings between August 2020 and May 2021. We collected data on participants' demographic characteristics, fatigue, nutritional status, physical activity, and QoL. We then adapted Hayes Process Macro to examine the mediating and moderating effects of nutrition and physical activity on the relationship between fatigue and QoL. RESULTS: In models adjusted for age and sex, (1) the simple mediation analysis identified the mediating effect of nutrition on the relationship between fatigue and QoL; and (2) the mediation and moderation analysis identified that the direct effect of nutrition between fatigue and QoL was significant when adding (a) physical activity and (b) fatigue × physical activity. There were significantly decreasing trends in physical activity at 1 standard deviation below the mean and at the mean, but not at 1 standard deviation above the mean. CONCLUSIONS: Our findings demonstrate that nutrition mediated and physical activity moderated the relationship between fatigue and QoL. This highlights an opportunity to enhance QoL among childhood cancer survivors through healthy lifestyle interventions. To ensure that future interventions address children's needs and promote the greatest impact, such interventions should include nutrition and physical activity components that involve nurses, pediatric oncology physicians, nutritionists, and physical therapists.

Sleep changes in Taiwanese first graders before and after school closure during the COVID-19 pandemic.

PURPOSE: The objective of this study was (1) to examine sleep changes in first graders before and after school closure and (2) to examine the association between parental work rearrangement and children's sleep change during the coronavirus disease 2019 (COVID-19) pandemic. DESIGN AND METHODS: This was an observational study. The children's sleep habit questionnaire was completed by 103 parents of first-graders before and after school closure. Paired t-test and the general linear model were applied to data analysis. RESULTS: Children delayed their bedtime and rising time, but total sleep duration increased. Moreover, parents who rearranged their work during the pandemic perceived more child parasomnia symptoms (p = .029) and less delayed sleep-wake patterns in their children. PRACTICAL IMPLICATION: Sleep is an indicator that reflects children's behavioral changes in response to the COVID-19 pandemic. As routine changes, parents should be aware of child's parasomnia symptoms. Nursing interventions could aim at promoting sufficient external cues in the daytime during home confinement.

Factors associated with walking performance among adolescents undergoing cancer treatment: A correlational study.

This study aimed to describe and compare the differences in walking performance between adolescent patients in inpatient wards and outpatient units, and to identify factors that influence walking performance among adolescents receiving cancer treatment. The cross-sectional study with correlational research design recruited 32 adolescents with cancer between February 2015 and March 2017 in two teaching hospitals in Taiwan. Descriptive, bivariate, and multivariate regression analyses were used. Participants' age, treatment setting, and symptom distress were significantly associated with number of walking steps. All independent variables in the model together accounted for 82.1% of variance. This study addresses a gap in the existing literature to identify associated factors that affected walking performance among adolescents undergoing cancer treatment. Our findings represent a pathway toward generating knowledge to enhance well-being for this unique population.

Conceptualizing Health Communication and its Impact on Patient Outcomes in Oncology Outpatient Settings: A Mixed-Methods Study.

OBJECTIVES: Informed by the dual process theory of supportive message, the aim of this study is to systematically describe symptom communication, including its relationship with patient outcomes. DATA SOURCES: This is a mixed-methods study with an exploratory design. By examining symptom communication that occurred in oncology and hospice outpatient clinics, the qualitative phase employed conversation analysis to validate a typology of interaction patterns. The subsequent quantitative phase examined the relationship between interaction patterns and patient outcomes. CONCLUSION: A total of 52 cancer patients' outpatient communications with their health care providers were included in the analysis. Ten unique interaction patterns were identified and defined. Among the 10 interaction patterns, some patterns are significantly associated with critical patient outcomes, including satisfaction, health communication self-efficacy, and symptom agreement between patients and their health care providers. This study represents one of the few mixed-methods studies to examine the patterns of real outpatient symptom communications and link them to concrete patient outcomes. IMPLICATIONS FOR NURSING PRACTICE: Our results present various interaction patterns that are commonly used in medical encounters and suggest that using some patterns affects critical patient outcomes.

Naoxintong Capsule for Secondary Prevention of Ischemic Stroke: A Multicenter, Randomized, and Placebo-Controlled Trial.

OBJECTIVE: To examine whether the combination of Naoxintong Capsule with standard care could further reduce the recurrence of ischemic stroke without increasing the risk of severe bleeding. METHODS: A total of 23 Chinese medical centers participated in this trial. Adult patients with a history of ischemic stroke were randomly assigned in a 1:1 ratio using a block design to receive either Naoxintong Capsule (1.2 g orally, twice a day) or placebo in addition to standard care. The primary endpoint was recurrence of ischemic stroke within 2 years. Secondary outcomes included myocardial infarction, death due to recurrent ischemic stroke, and all-cause mortality. The safety of drugs was monitored. Results were analyzed using the intention-to-treat principle. RESULTS: A total of 2,200 patients were enrolled from March 2015 to March 2016, of whom 143 and 158 in the Naoxintong and placebo groups were lost to follow-up, respectively. Compared with the placebo group, the recurrence rate of ischemic stroke within 2 years was significantly lower in the Naoxintong group [6.5% vs. 9.5%, hazard ratio (HR): 0.665, 95% confidence interval (CI): 0.492-0.899, P=0.008]. The two groups showed no significant differences in the secondary outcomes and safety, including rates of severe hemorrhage, cerebral hemorrhage and subarachnoid hemorrhage (P>0.05). CONCLUSION: The combination of Naoxintong Capsule with standard care reduced the 2-year stroke recurrence rate in patients with ischemic stroke without increasing the risk of severe hemorrhage in high-risk patients. (Trial registration No. NCT02334969).

The effect of a multidisciplinary lifestyle modification program for obese and overweight children.

BACKGROUND/PURPOSE: The increasing prevalence of overweight and obese children and adolescents has been recognized as a public health threat worldwide. This study aimed to assess the effect of a stepwise lifestyle intervention in children and adolescents. METHODS: We developed a multidisciplinary clinic aimed at providing lifestyle interventions for obese children and adolescents. The program comprised three stages with stepwise goals: knowledge building (the first 4 weeks), habit consolidation (5-12 weeks), and self-monitoring (13-20 weeks). RESULTS: Of the 63 participants (age 11.6 ± 3.2 years) who entered the first stage of the program, 48, 22, and 15 completed the first, second and third stages (4, 12, and 20 weeks), respectively. In the first stage, significant improvement was noted in body weight, body mass index (BMI), BMI z-score, and waist circumference. Improvements in physical fitness performance were observed at 4 weeks in 3/5 items and at 12 weeks in 4/5 items. The decreases in body weight, BMI and BMI z-score were most prominent in the first two stages. In the third stage, participants maintained a stable body weight. In the 15 subjects who completed the whole program, BMI decreased from 29.3 ± 6.9 to 27.8 ± 6.1 (P = 0.001), and BMI z-score decreased from 3.06 ± 0.96 to 2.69 ± 0.91(P = 0.001). CONCLUSION: We developed a feasible multidisciplinary program based on knowledge education and individualized training. BMI and physical fitness scores can be used as early indicators of lifestyle change for obese children and adolescents.

Sleep pattern regularity and measures of infant weight and length during the first 6 months.

PURPOSE: To examine the association between sleep pattern regularity and measures of weight and length in infants. DESIGN AND METHODS: This was a prospective observational study conducted in a university-affiliated children's hospital in northern Taiwan. A total of 316 healthy infants recruited during their 6-month well-child checkups had their weight and recumbent length measured, and wore an actigraph on the ankle for a week. Based on average weekday, weekend, and all-week sleep durations, infants were categorized into 3 groups: regular sleep, weekend catch-up sleep, and weekend sleep curtailment. General linear model analyses were performed with the 3 sleep regularity groups as the primary predictor variable of interest and infant anthropometry as the dependent variable. RESULTS: At risk of overweight, overweight, and obese was present in a total of 62 (19.6%) infants. In both unadjusted and adjusted models, infants in the weekend catch-up sleep group (30.4%) and those in the weekend sleep curtailment group (34.5%) had significantly higher weight-to-length ratios, body mass index, weight-for-age z-scores, and weight velocity of 6-month increments z-scores when compared with infants in the regular sleep group (35.1%, all p < 0.05). CONCLUSIONS: Differences in weekday-weekend sleep exist as early as in the first 6 months of life, and both catch-up sleep and sleep curtailment over the weekend is associated with higher measures of weight and length in infants. PRACTICE IMPLICATIONS: Sleep assessments in well-child checkups should include not only global assessments of average sleep duration but also address sleep patterns and their regularity.

The effectiveness of a medical clowning program on improving emotional status among hospitalized children undergoing cancer treatment: A quasi-experimental study.

PURPOSE: To examine the effectiveness of one-time medical clowning on improving short-term positive emotions among hospitalized children undergoing cancer treatment, and to analyze whether age moderates this effect. DESIGN: In this quasi-experimental research study, we recruited a pooled sample of 96 children who were undergoing cancer treatment in pediatric oncology/hematology wards at three university-affiliated medical centers in Taiwan from June 2018 through April 2020. METHODS: Children's demographic characteristics, symptom distress, quality of life, and pretest emotional status were collected at T1. At T2, we collected only posttest emotional status. We adapted generalized estimating equation models to evaluate the effectiveness of medical clowning on enhancing positive emotions. FINDINGS: Changes in the probabilities of positive emotion were significantly different across groups (51.84% for the experimental group, 15.76% for the control group; Δ = 36.08, p = 0.001), and the change was more than two times larger for the experimental group (effect ratio = 3.28, p < 0.05) than for the control group. When evaluating the moderating effect of age on the intervention, none of the coefficients reached the significant (p < 0.05) levels, suggesting that age may not moderate the intervention effect. CONCLUSION: This study demonstrates the core value of medical clowning in child-friendly health care. Our findings clearly support the benefit of the one-time medical clowning program on enhancing short-term emotional well-being across age groups of children. Medical clowning programs should be strongly encouraged and supported in pediatric oncology wards. CLINICAL RELEVANCE: Medical clowning programs should be widely and continuously implemented in pediatric oncology wards as a routine clinical practice for enhancing emotional well-being among children receiving cancer treatment. Nurses need to be aware of medical clowning's equal effectiveness across age groups, not only or better for younger children.

Associations Between Fatigue, Sleep Disturbance, Physical Activity, and Quality of Life for Children With Cancer: A Correlational Study.

BACKGROUND: Fatigue, sleep disturbance, and physical inactivity have been increasingly recognized as health issues that negatively affect quality of life (QoL) for children with cancer. Existing studies focus either on children receiving treatment or in survivorship, but not on both populations in a study. This causes difficulty in examining differences of these issues between treatment statuses and identifying associations of these issues with QoL. OBJECTIVE: The aims of this study were to examine differences in fatigue, sleep disturbance, physical activity, and QoL between on- and off-treatment children and to identify their associations with QoL. METHODS: The correlational study was conducted with 100 children with cancer 7 to 12 years old. Descriptive, bivariate, and multivariate regression analyses were used. RESULTS: Participants undergoing treatment had higher degrees of fatigue ( P = .002), physical inactivity ( P = .004), and QoL distress ( P = .001) than those in survivorship. Mean sums (SDs) of sleep disturbance were 47.15 (8.23) and 48.48 (7.13) in the on- and off-treatment groups. Age ( P = .000), sex ( P = .023), fatigue ( P = .000), and sleep disturbance ( P = .004) were significantly associated with QoL distress. CONCLUSIONS: This study is unique in that a frame of reference is addressed to gain insight into the distinct developmental issues of school-aged children undergoing cancer treatment and in survivorship. More studies are needed. IMPLICATIONS FOR PRACTICE: Interventions to increase QoL should target children who are younger, male, and have higher levels of fatigue and sleep disturbance. Diagnosis and treatment of sleep disturbance should be considered as part of routine activities.

Leukoaraiosis is associated with clinical symptom severity, poor neurological function prognosis and stroke recurrence in mild intracerebral hemorrhage: a prospective multi-center cohort study.

Leukoaraiosis (LA) results from ischemic injury in small cerebral vessels, which may be attributable to decreased vascular density, reduced cerebrovascular angiogenesis, decreased cerebral blood flow, or microcirculatory dysfunction in the brain. In this study, we enrolled 357 patients with mild intracerebral hemorrhage (ICH) from five hospitals in China and analyzed the relationships between LA and clinical symptom severity at admission, neurological function prognosis at 3 months, and 1-year stroke recurrence. Patients were divided into groups based on Fazekas scale scores: no LA (n = 83), mild LA (n = 64), moderate LA (n = 98) and severe LA (n = 112). More severe LA, larger hematoma volume, and higher blood glucose level at admission were associated with more severe neurological deficit. More severe LA, older age and larger hematoma volume were associated with worse neurological function prognosis at 3 months. In addition, moderate-to-severe LA, admission glucose and symptom-free cerebral infarction were associated with 1-year stroke recurrence. These findings suggest that LA severity may be a potential marker of individual ICH vulnerability, which can be characterized by poor tolerance to intracerebral attack or poor recovery ability after ICH. Evaluating LA severity in patients with mild ICH may help neurologists to optimize treatment protocols. This study was approved by the Ethics Committee of Ruijin Hospital Affiliated to Shanghai Jiao Tong University (approval No. 12) on March 10, 2011.

Explore the correlation between cerebral vessel characteristics with cognitive impairment among elder individuals: a community study from China.

BACKGROUND: Brain Magnetic Resonance Imaging (MRI) examination of cerebral small vessel disease (CSVD) may help screen vascular cognitive impairment. A recently estimated CSVD score system was suggested to capture the overall CSVD burden. The study aimed to detect the association between systemic evaluation score of cerebral vascular imaging parameters with cognitive functions. METHODS: This was a cross-sectional study in community settings. From October 2017 to September 2018, elder (≧60) residents were recruited through on-site visit in 6 communities from Shanghai, China. The participants underwent brain MRI, carotid ultrasound, laboratory tests of blood and urine samples. Cognitive function was evaluated using Mini-Mental State Examination (MMSE). MRI score of CSVD was calculated according to the 2012 standard for the evaluation of statistical changes in imaging. RESULTS: Total 171 subjects completed survey and examinations. There were 55 participants diagnosed with cognitive impairment, with a total percentage of 32.2%. Participants with and without cognitive impairment showed significant differences in age, BMI and education level. Cognitive impaired participant had more disease history/comorbidity of hypertension and chronic renal insufficiency, higher level of creatinine, as well as lower level of full blood count (FBC) and alanine aminotransferase (ALT). A significant difference was detected in CSVD score between participants with and without cognitive impairment. Results of linear regression analysis showed significant negative correlations between MMSE score and both left and right carotid artery peak systolic velocity (PSV), however the CSVD score was only borderline (P = 0.0566) positively correlated with MMSE. Multivariate linear correlation analysis including all collected risk factor data showed that left carotid artery PSV score was among the independent negative correlated factors of MMSE. Multivariate binary logistic analysis showed that age, education and history of hypertension were the only statistically associated factors of cognitive impairment. CONCLUSIONS: The current study identified high prevalence of cognitive impairment in a Chinese community. In addition, correlations between cerebral vascular disease imaging status and cognitive functions were confirmed although the sample size limited the possibility of screening cognitive impairment with imaging technique.

Factors influencing the protective behavior of individuals during COVID-19: a transnational survey.

To slow the spread of infectious disease, it is crucial to understand the engagement of protective behavior among individuals. The purpose of this study was to systematically examine individuals' protective behaviors and the associated factors across countries during COVID-19. This causal-comparative study used a self-developed online survey to assess individuals' level of engagement with six protective behaviors. Analysis of variance and McNemar's test were employed for data analysis. Three hundred and eighty-four responses were analyzed. The majority of participants lived in three areas: Taiwan, Japan, and North America. Overall, the participants reported a high level of engagement in protective behaviors. However, engagement levels varied according to several demographic variables. Hand hygiene and cleaning/ventilation are two independent behaviors that differ from almost all other protective behaviors. There is a need to target the population at risk, which demonstrates low compliance. Different strategies are needed to promote specific protective behaviors.
