Comparing Outcomes of Thrombectomy Versus Intravenous Thrombolysis Based on Middle Cerebral Artery M2 Occlusion Features.

BACKGROUND: Current evidence provides limited support for the superiority of endovascular thrombectomy (EVT) in patients with M2 segment middle cerebral artery occlusion. We aim to investigate whether imaging features of M2 segment occlusion impact the effectiveness of EVT. METHODS: We conducted a retrospective cohort study from January 2017 to January 2022, drawing data from the CASE II registry (Computer-Based Online Database of Acute Stroke Patients for Stroke Management Quality Evaluation), which specifically documented patients with acute ischemic stroke presenting with M2 segment occlusion undergoing reperfusion therapy. Patients were stratified into the intravenous thrombolysis (IVT) group (IVT alone) and EVT group (IVT plus EVT or EVT alone). The primary outcome was a modified Rankin Scale score 0 to 2 at 90 days. Secondary outcomes included additional thresholds and distribution of modified Rankin Scale scores, 24-hour recanalization, early neurological deterioration, and relevant complications during hospitalization. Safety outcomes encompassed intracranial hemorrhagic events at 24 hours and mortality at 90 days. Binary logistic regression analyses with propensity score matching were used. Subgroup analyses were performed based on the anatomic site of occlusion, including right versus left, proximal versus distal, dominant/co-dominant versus nondominant, single versus double/triple branch(es), and anterior versus central/posterior branch. RESULTS: Among 734 patients (43.3% were females; median age, 73 years) with M2 segment occlusion, 342 (46.6%) were in the EVT group. Propensity score matching analysis revealed no statistical difference in the primary outcome (odds ratio, 0.860 [95% CI, 0.611-1.209]; P=0.385) between the EVT group and IVT group. However, EVT was associated with a higher incidence of subarachnoid hemorrhage (odds ratio, 6.655 [95% CI, 1.487-29.788]; P=0.004) and pneumonia (odds ratio, 2.015 [95% CI, 1.364-2.977]; P<0.001). Subgroup analyses indicated that patients in the IVT group achieved better outcomes when presenting with right, distal, or nondominant branch occlusion (Pall interaction<0.05). CONCLUSIONS: Our study showed similar efficiency of EVT versus IVT alone in acute M2 segment middle cerebral artery occlusion. This suggested that only specific patient subpopulations might have a potentially higher benefit of EVT over IVT alone. REGISTRATION: URL: https://clinicaltrials.gov; Unique identifier: NCT04487340.

Nursing Workloads and Lower Urinary Tract Symptoms Among Chinese Female Nurses: The Mediating Role of Delayed Voiding Behaviors.

PURPOSE: Lower urinary tract symptoms (LUTS) are a challenge to the healthy nursing workforce. Nurses confront various objective and subjective nursing workloads which contribute to their LUTS, but less is known about how nursing workloads influence their LUTS. This study is designed to test hypotheses that delayed voiding behaviors mediate the relationships between nursing workloads and LUTS in female nurses. MATERIALS AND METHODS: This study analyzed the baseline data collected from an ongoing cohort study named Nurse Urinary Related Health Study in China. LUTS of nurses in 20 tertiary hospitals were assessed with the International Consultation on Incontinence Questionnaire‒Female Lower Urinary Tract Symptoms. Objective nursing workloads including working environment, working hours, and working schedule were collected, and perceived stress, the proxy of the subjective nursing workload, was assessed with the Perceived Stress Scale. Delayed voiding behaviors were assessed with 3 questions adapted from the Taiwan Nurse Bladder Survey. Structural equation modeling was used to run the mediation model. RESULTS: More than half (51%) of 13,191 female nurses had LUTS. Median age was 31 years (IQR 27-37). When delayed voiding behaviors served as a mediator, the direct effects of subjective nursing workload rather than objective nursing workloads on LUTS were significant. CONCLUSIONS: Nursing workloads influence nurses' LUTS via delayed voiding behaviors. Strategies tailored to delayed voiding behaviors should be developed, and these may work with stress-reducing strategies as the gatekeepers for nurses' bladder health.

Relationship between fear of falling and quality of life in nursing home residents: The role of activity restriction.

This study investigates the mediating role of activity restriction in the relationship between the fear of falling and health outcomes. This was a cross-sectional study with convenience sampling of 316 nursing home residents. Generalized structural equation modeling was conducted to test the mediating role. The results showed that residents with fear of falling were more likely to restrict their activities and residents who often or always restricted activities reported lower levels of quality of life and higher levels of depression. Severe activity restriction accounted for 75 % of the total effect of fear of falling on quality of life and 69 % of the total effect of fear of falling on depression. Fall prevention efforts should focus on strategies or interventions to reduce residents' excessive fear of falling and promote activity engagement. Physical and social activities will not only prevent future falls but also improve residents' quality of life and mental health.

Safety of early antiplatelet therapy for non-cardioembolic mild stroke patients with thrombocytopenia. / åˆå¹¶è¡€å°æ¿å‡å°‘ç—‡çš„éžå¿ƒæºæ€§è½»åž‹è„‘å’ä¸­æ‚£è€ æ—©æœŸæŠ—è¡€å°æ¿æ²»ç–—çš„å®‰å ¨æ€§ç ”ç©¶.

OBJECTIVES: To investigate the safety of early antiplatelet therapy for non-cardioembolic mild stroke patients with thrombocytopenia. METHODS: Data of acute ischemic stroke patients with baseline National Institutes of Health Stroke Scale (NIHSS) score ≤3 and a platelet count <100×109/L were obtained from a multicenter register. Those who required anticoagulation or had other contraindications to antiplatelet therapy were excluded. Short-term safety outcomes were in-hospital bleeding events, while the long-term safety outcome was a 1-year all-cause death. The short-term neurological outcomes were evaluated by modified Rankin scale (mRS) score at discharge. RESULTS: A total of 1868 non-cardioembolic mild stroke patients with thrombocytopenia were enrolled. Multivariate regression analyses showed that mono-antiplatelet therapy significantly increased the proportion of mRS score of 0-1 at discharge (OR=1.657, 95%CI: 1.253-2.192, P<0.01) and did not increase the risk of intracranial hemorrhage (OR=2.359, 95%CI: 0.301-18.503, P>0.05), compared with those without antiplatelet therapy. However, dual-antiplatelet therapy did not bring more neurological benefits (OR=0.923, 95%CI: 0.690-1.234, P>0.05), but increased the risk of gastrointestinal bleeding (OR=2.837, 95%CI: 1.311-6.136, P<0.01) compared with those with mono-antiplatelet therapy. For patients with platelet counts ≤75×109/L and >90×109/L, antiplatelet therapy significantly improved neurological functional outcomes (both P<0.05). For those with platelet counts (>75-90)×109/L, antiplatelet therapy resulted in a significant improvement of 1-year survival (P<0.05). For patients even with concurrent coagulation abnormalities, mono-antiplatelet therapy did not increase the risk of various types of bleeding (all P>0.05) but improved neurological functional outcomes (all P<0.01). There was no significant difference in the occurrence of bleeding events, 1-year all-cause mortality risk, and neurological functional outcomes between aspirin and clopidogrel (all P>0.05). CONCLUSIONS: For non-cardioembolic mild stroke patients with thrombocytopenia, antiplatelet therapy remains a reasonable choice. Mono-antiplatelet therapy has the same efficiency as dual-antiplatelet therapy in neurological outcome improvement with lower risk of gastrointestinal bleeding.

The sleep patterns and their associations with mental health among nursing home residents: a latent profile approach.

BACKGROUND: Nursing home residents commonly experience poor sleep conditions. However, few studies have explored the potential sleep patterns among nursing home residents. This study aimed to identify the sleep patterns in nursing home residents, compare residents' characteristics across sleep patterns, and examine the relationships between sleep patterns and residents' mental health (i.e., depressive and anxiety symptoms). METHODS: This cross-sectional study was conducted in 27 nursing homes in Jinan, China, from March to June 2018. In total, 353 participants were recruited via convenience sampling, and of which, 326 completed the survey. A latent profile analysis was performed to identify sleep patterns based on the seven dimensions of the Pittsburgh Sleep Quality Index. Bivariate analyses were conducted to compare residents' characteristics among the sleep patterns. Mixed-effects logistic regression analyses were adopted to investigate the relationships between sleep patterns and residents' mental health. RESULTS: Three sleep patterns were identified, including 'good sleepers', 'poor sleepers without hypnotic use', and 'poor sleepers with hypnotic use'. Residents' gender, education, pain, instrumental activities of daily living, and number of chronic conditions were significantly differentiated across the sleep patterns. Compared with 'good sleepers', 'poor sleepers without hypnotic use' were significantly associated with more depressive symptoms (OR = 3.73, 95% CI = 2.09, 6.65, p < 0.001), but not with anxiety symptoms (OR = 2.04, 95% CI = 0.97, 4.29, p = 0.062); whereas 'poor sleepers with hypnotic use' had significantly more depressive (OR = 5.24, 95% CI = 2.54, 10.79, p < 0.001) and anxiety symptoms (OR = 5.02, 95% CI = 2.13, 11.83, p < 0.001). CONCLUSIONS: This study reveals three distinct sleep patterns in nursing home residents and their significant associations with residents' mental health. These findings can inform future research to develop appropriate and tailored intervention strategies for improving sleep and promoting mental health for nursing home residents.

Stroke outcome of early antiplatelet in post-thrombolysis haemorrhagic infarction.

BACKGROUND AND PURPOSE: Initiation of early antiplatelet (EA) therapy after acute ischaemic stroke (AIS) is essential. We aimed to investigate the safety and effectiveness of EA therapy in patients who had an AIS with haemorrhagic infarction (HI) after intravenous thrombolysis (IVT). METHODS: Based on a multicentre stroke registry database, patients who had an AIS with post-thrombolysis HI at 24 hours were identified. EA users and non-EA users were defined as patients with HI who received or did not receive antiplatelet therapy between 24 and 48 hours after IVT. Primary outcome was favourable outcome defined as modified Rankin Scale scores 0-2 at 3 months. Secondary outcomes were early neurological deterioration (END) and haemorrhagic transformation expansion. RESULTS: A total of 842 patients with HI were identified from 24 061 thrombolytic patients within 4.5 hours, and 341 (40.5%) received EA therapy. EA users were more likely to have a favourable outcome (55.7% vs 39.5%, OR 1.565; 95% CI 1.122 to 2.182; p=0.008) and lower rate of END (12.6% vs 21.4%, OR 0.585; 95% CI 0.391 to 0.875; p=0.009) compared with non-EA users. EA therapy was not associated with haemorrhagic transformation expansion (p=0.125). After propensity score matching, EA therapy was still independently associated with favourable outcome (54.3% vs 46.3%, OR 1.495; 95% CI 1.031 to 2.167; p=0.038) and lower risk of END (13.5% vs 21.2%, OR 0.544; 95% CI 0.350 to 0.845; p=0.007). CONCLUSIONS: Antiplatelet therapy can be safely used between 24 and 48 hours when HI occurs after IVT, and such therapy is associated with reduced risk of END and improved neurological outcome in patients who had an AIS.

Post-COVID-19 Epidemic: Allostatic Load among Medical and Nonmedical Workers in China.

BACKGROUND: As the fight against the COVID-19 epidemic continues, medical workers may have allostatic load. OBJECTIVE: During the reopening of society, medical and nonmedical workers were compared in terms of allostatic load. METHODS: An online study was performed; 3,590 Chinese subjects were analyzed. Socio-demographic variables, allostatic load, stress, abnormal illness behavior, global well-being, mental status, and social support were assessed. RESULTS: There was no difference in allostatic load in medical workers compared to nonmedical workers (15.8 vs. 17.8%; p = 0.22). Multivariate conditional logistic regression revealed that anxiety (OR = 1.24; 95% CI 1.18-1.31; p < 0.01), depression (OR = 1.23; 95% CI 1.17-1.29; p < 0.01), somatization (OR = 1.20; 95% CI 1.14-1.25; p < 0.01), hostility (OR = 1.24; 95% CI 1.18-1.30; p < 0.01), and abnormal illness behavior (OR = 1.49; 95% CI 1.34-1.66; p < 0.01) were positively associated with allostatic load, while objective support (OR = 0.84; 95% CI 0.78-0.89; p < 0.01), subjective support (OR = 0.84; 95% CI 0.80-0.88; p < 0.01), utilization of support (OR = 0.80; 95% CI 0.72-0.88; p < 0.01), social support (OR = 0.90; 95% CI 0.87-0.93; p < 0.01), and global well-being (OR = 0.30; 95% CI 0.22-0.41; p < 0.01) were negatively associated. CONCLUSIONS: In the post-COVID-19 epidemic time, medical and nonmedical workers had similar allostatic load. Psychological distress and abnormal illness behavior were risk factors for it, while social support could relieve it.

Longitudinal trajectories of physical functioning among Chinese older adults: the role of depressive symptoms, cognitive functioning and subjective memory.

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.

Compositional and functional alterations of gut microbiota in patients with stroke.

BACKGROUND AND AIMS: There is accumulating evidence that gut microbiota plays a key role in cardiovascular diseases. Gut bacteria can transform dietary choline, l-carnitine, and trimethylamine N-oxide (TMAO) into trimethylamine, which can be oxidized into TMAO again in the liver. However, the alterations of the gut microbiota in large artery atherosclerotic (LAA) stroke and cardioembolic (CE) stroke have been less studied. METHODS AND RESULTS: We performed a case-control study in patients with LAA and CE types of strokes. We profiled the gut microbiome using Illumina sequencing of the 16S ribosomal RNA gene (V4-V5 regions), and TMAO was determined via liquid chromatography-tandem mass spectrometry. Our results showed that the TMAO levels in the plasma of patients with LAA and CE strokes were significantly higher than those in controls (LAA stroke, 2931 ± 456.4 ng/mL; CE stroke, 4220 ± 577.6 ng/mL; healthy control, 1663 ± 117.8 ng/mL; adjusted p < 0.05). The TMAO level in the plasma of patients with LAA stroke was positively correlated with the carotid plaque area (rho = 0.333, 95% CI = 0.08-0.55, p = 0.0093). Notably, the composition and the function of gut microbiota in the LAA stroke group were significantly different from those in the control group (FDR-adjusted p-value < 0.05). There was no significant association between gut microbiota and CE stroke in our study. CONCLUSION: This study provides evidence for significant compositional and functional alterations of the gut microbiome in patients with LAA stroke. Gut microbiota might serve as a potential biomarker for patients with LAA stroke.

A Comparison of Voice Recognition Program and Traditional Keyboard Charting for Nurse Documentation.

The purposes of this study are threefold: (1) compare the document times between a voice recognition system and keyboard charting, (2) compare the number of errors between the two methods, and (3) identify factors influencing documentation time. Voice recognition systems are considered a potential solution to decrease documentation time. However, little is known to what extent voice recognition systems can save nurses' documentation time. A pilot, simulation study was conducted using a voice recognition system and keyboard charting with 15 acute care nurses. A crossover method with repeated measures was utilized. Each nurse was given two simple and two complex assessment scenarios, assigned in random order, to document using both methods. Paired t-tests and multivariate linear regression models were used for data analysis. The voice recognition method saved the nurses 2.3 minutes (simple scenario) and 6.1 minutes (complex scenario) on average and was statistically significant (P < .001). There were no significant differences in errors or factors identified influencing documentation times. Eighty percent reported a preference of using voice recognition systems, and 87% agreed this method helped speed up charting. This study can show how a voice recognition system can improve documentation times compared with keyboard charting while still having thorough documentation.

Obesity and Hair Cortisol: Relationships Varied Between Low-Income Preschoolers and Mothers.

PURPOSE: Literature on the relationship between hair cortisol concentration (HCC) and body mass index (BMI) is scarce and inconsistent in both preschoolers and parents. Thus, the study aimed to examine the relationships among HCC, perceived distress, coping, and BMI among low-income Head Start preschoolers and mothers. METHODS: A cross-sectional, correlational study was conducted with a non-random sample of 35 mother-preschooler dyads. Height and weight were measured using a ShorrBoard Stadiometer and a Seca portable electronic scale, respectively. HCC was extracted using the enzyme immunoassay approach. Mothers' perceived distress and coping were assessed by Cohen's Perceived Stress Scale. RESULTS: Mothers' mean age was 29.74 years, and preschoolers' mean age was 4.69 years. The sample included 17% Hispanic, 54% Black, and 60% single mothers; and 23% Hispanic and 60% Black preschoolers. Compared to mothers in low HCC group (< 4.1 pg/mg), mothers in high HCC group (≥ 4.1 pg/mg) had lower BMI (B = - 4.62, p = .049). The indirect effects of mothers' HCC on BMI via perceived distress and coping was 15% of the total effects. Preschoolers with mothers in high HCC group had significantly lower BMI z-score than those with mothers in low HCC group (B = - 0.94, p = .043). Preschoolers' HCC had a small positive correlation with their BMI z-score (B = 0.01, p = .112). CONCLUSIONS: Relationships between HCC and BMI varied between low-income mothers and preschoolers. A stress management component may need to be integrated into future obesity interventions. Given the limitation of small sample size and cross-sectional study design, the findings need to be interpreted with caution, and further investigation is warranted.

Difficulties with health self-management by older adults: The role of well-being.

The purpose of this study was to investigate the association between three aspects of well-being (positive and negative affect, self-realization, and self-efficacy and resilience) and disease self-management or difficulties in managing care. Logistic regression models were used to analyze data from a sample of community-dwelling Medicare beneficiaries 65-years or older who participated in the National Health and Aging Trends Study and responded to well-being and engagement in health care questions (n = 1663). All three aspects of well-being were significantly associated with reduced difficulties in care management for both the participants and their family and friends who assist them. Self-efficacy and resilience had the strongest association; older adults with higher levels of self-efficacy and resilience were more likely to handle care by self. Our findings highlight the importance of incorporating strategies to enhance well-being of older adults to reduce the difficulties of managing activities necessary to stay healthy.

Development of a quality of life questionnaire for nursing home residents in mainland China.

OBJECTIVE: To develop and validate a quality of life (QOL) questionnaire for nursing home (NH) residents in mainland China. METHODS: A cross-sectional study including a development sample (n = 176) and validation sample (n = 371) of NH residents aged 60 and older was conducted between 2015 and 2016 in Jinan, Shandong Province, China. Resident interviews, literature reviews, expert panels, and pilot studies were used to identify QOL domains and items pertinent to NH life. Exploratory and confirmatory factor analysis were used to develop and validate a QOL questionnaire. Reliability (internal consistency, spilt-half reliability, and test-retest reliability) and validity (construct and criterion validity) were evaluated for the questionnaire. RESULTS: The self-report Chinese NH QOL questionnaire had 9 domains and 38 items including physical health (4 items), food enjoyment (6 items), security (3 items), environmental comfort (5 items), autonomy (2 items), meaningful activity (3 items), interrelationship (6 items), family relationships (3 items), and mood (6 items). The nine-factor model was confirmed with the following fit indices: χ2/df = 1.872, root mean square error of approximation = 0.049, comparative fit index = 0.913, and Tucker-Lewis index = 0.903. The 38-item NH QOL questionnaire showed satisfactory construct validity, criterion validity, internal consistency (Cronbach's alpha = 0.89, spilt-half reliability = 0.73, test-retest reliability = 0.76). CONCLUSIONS: The NH QOL questionnaire appears to be a reliable and valid instrument and should be incorporated into a set of quality measures for use with NH residents in mainland China.

Relationships among occupational stress, toileting behaviors, and overactive bladder in nurses: A multiple mediator model.

AIMS: To investigate: (a) the prevalence of overactive bladder among male and female operating room nurses; (b) the unhealthy toileting behaviours that nurses adopt to void their bladders; and (c) the mediating roles that different toileting behaviours play in the relationship between occupational stress and overactive bladder. DESIGN: A cross-sectional design was used. METHODS: This study was conducted from July - September 2016 in Jinan, China. Four hundred eligible operating room nurses in five hospitals were recruited. Data were collected through survey questionnaires including the nurse job stress scale, the toileting behaviours scale and the overactive bladder symptom score questionnaire. Multivariate linear or logistic regression models, as appropriate, were used to test the mediation effect of each toileting behaviour on the relationship between occupational stress and overactive bladder. RESULTS: Overactive bladder was highly prevalent in both male and female nurses working in operating rooms. Approximately one of three nurses reported experiencing an overactive bladder. The most common unhealthy toileting behaviour was delayed voiding. Unhealthy toileting behaviours mediated the relationship between occupational stress and overactive bladder. With high levels of occupational stress, nurses tended to adopt unhealthy toileting behaviours to empty their bladders. The more the nurses engaged in unhealthy toileting behaviours (e.g. delayed voiding and straining to void), the greater the likelihood of having overactive bladders. CONCLUSIONS: This study highlights the mediating role of toileting behaviours on occupational stress and overactive bladder. To accommodate occupational stress, nurses engaged in unhealthy toileting behaviours that were detrimental to their bladder health.

[Effects of emergency medical service on prognosis of ischemic stroke patients treated with intravenous thrombolysis].

OBJECTIVE: To investigate the effect of emergency medical service (EMS) on the prognosis of ischemic stroke patients treated with intravenous thrombolysis. METHODS: Clinical data of 2123 ischemic stroke patients treated with intravenous thrombolysis in 70 hospitals in Zhejiang province were retrospectively analyzed. There were 808 patients sent to the hospital by ambulance (EMS group) and 1315 patients by other transportations (non-EMS group). Good outcome was defined as modified Rankin Scale (mRS) ≤ 2 at 3-month. The onset to needle time (ONT), onset to door time (ODT), door to needle time (DNT) and outcome were compared between EMS group and non-EMS group. Binary logistic regression was used to explore the influencing factors for the outcome at 3-month. RESULTS: Compared with the non-EMS group, patients in the EMS group were older, with higher baseline National Institute of Health Sroke Scale (NIHSS) score, and had a higher proportion of atrial fibrillation (all P<0.05), but there were no significant differences in ONT, ODT and DNT between two groups (all P>0.05). Binary logistic regression showed that EMS was not independently associated with good outcome (OR=0.856, 95%CI:0.664-1.103, P>0.05). CONCLUSIONS: EMS had not improve the outcome of patients receiving intravenous thrombolysis in Zhejiang province.

[Advanced treatment time improves outcomes of patients with ischemic stroke undergoing reperfusion therapy].

OBJECTIVE: To investigate the effect of treatment time on the outcome of patients with ischemic stroke undergoing reperfusion therapy. METHODS: The clinical data of 3229 ischemic stroke patients who received intravenous thrombolysis with or without arterial thrombolysis from 71 hospitals in Zhejiang province from June 2017 to September 2018 were retrospectively reviewed. The good outcome was defined as modified Rankin Scale (mRS) ≤ 2. Binary logistic regression analysis was used to investigate the association of door to needle time (DNT), or door to reperfusion time (DRT) with the outcomes in patients treated by intravenous thrombolysis or bridging arterial thrombolysis, respectively. RESULTS: Binary logistic regression showed that DNT (OR=0.994, 95%CI:0.991-0.997, P<0.01) or DRT (OR=0.989, 95%CI:0.983-0.995, P<0.01) were independently associated with good outcomes, respectively. Every hour decreases in DNT resulted in a 4.7%increased probability of functional independence (mRS 0-2) in patients treated by intravenous thrombolysis; Every hour decreases in DRT was associated with a 11.4%increased probability of functional independence in patients treated by intravenous thrombolysis with arterial thrombolysis. CONCLUSIONS: Good outcomes are associated with lower DNT in ischemic stroke patients treated by intravenous thrombolysis or lower DRT in patients treated by intravenous thrombolysis bridging arterial thrombolysis.

[Analysis of intravenous thrombolysis time and prognosis in patients with in-hospital stroke].

OBJECTIVE: To compare the time delay between in-hospital stroke and out-of-hospital stroke patients, and to explore the influence factors for the prognosis of in-hospital stroke patients treated by intravenous thrombolysis. METHODS: Clinical data of 3050 patients with ischemic stroke who received intravenous thrombolysis in 71 hospitals in Zhejiang province from June 2017 to September 2018 were analyzed. Differences of time delay including door to imaging time (DIT), imaging to needle time (INT) and door to needle time (DNT) between in-hospital stroke (n=101) and out-of-hospital stroke (n=2949) were observed. The influencing factors for the outcome at 3 month after intravenous thrombolysis in patients with in-hospital stroke were analyzed using binary logistic regression analysis. RESULTS: Patients with in-hospital stroke had longer DIT[53.5 (32.0-79.8) min vs. 20.0 (14.0-28.0) min, P<0.01], longer IDT[47.5(27.3-64.0)min vs. 36.0(24.0-53.0)min, P<0.01], and longer DNT[99.0 (70.5-140.5) min vs. 55.0 (41.0-74.0) min, P<0.01], compared with patients with out-of-hospital stroke; patients in comprehensive stroke center had longer DIT[59.5(44.5-83.3) min vs. 37.5(16.5-63.5) min, P<0.01], longer DNT[110.0(77.0-145.0) min vs. 88.0 (53.8-124.3) min, P<0.05], but shorter INT[36.5(23.8-60.3)min vs. 53.5 (34.3-64.8) min, P<0.05], compared with patients in primary stroke center. Age (OR=0.934, 95%CI: 0.882-0.989, P<0.05) and baseline National Institute of Health Stroke Scale score (OR=0.912, 95%CI: 0.855-0.973, P<0.01) were independent risk factors for prognosis of in-hospital stroke patients. CONCLUSIONS: In-hospital stroke had longer DIT and DNT than out-of-hospital stroke, which suggests that a more smooth thrombolysis process of in-hospital stroke should be established.

[Association of atrial fibrillation with hemorrhagic transformation after intravenous thrombolysis in patients with ischemic stroke].

OBJECTIVE: To investigate the association of atrial fibrillation (AF) with hemorrhagic transformation (HT) in patients with ischemic stroke treated by intravenous thrombolysis. METHODS: Clinical data of 3272 patients treated by intravenous thrombolysis from 71 hospitals in Zhejiang Province during June 2017 and December 2018 were retrospectively reviewed. Intracranial HT was defined as intracranial hemorrhage suggested by imaging examination 24 hours after intravenous thrombolysis. Patients were dichotomized into HT group (n=533) and non-HT group (n=2739). The association of AF and HT was analyzed by univariate analysis and binary logistic regression. RESULTS: Compared with the non-HT group, the HT group were older, had longer onset to needle time (ONT), higher baseline National Institute of Health Stroke Scale (NIHSS) score, higher baseline glucose level, and higher AF rate (P<0.05 or P<0.01). Binary logistic regression analysis revealed that AF was independently associated with HT (OR=2.527, 95%CI:2.030-3.146, P<0.01). CONCLUSIONS: AF is independently associated with the occurrence of HT in ischemic stroke patients treated with intravenous thrombolysis.

[Effect of different working time on the prognosis of ischemic stroke patients undergoing intravenous thrombolysis].

OBJECTIVE: To investigate the effect of working time on the prognosis of patients with ischemic stroke undergoing intravenous thrombolysis. METHODS: Clinical data of 3050 patients with ischemic stroke received intravenous thrombolysis from 71 hospitals in Zhejiang Province during June 2017 and September 2018 were retrospective analyzed. Whole day of Saturday and Sunday were defined as weekend; whole day of Monday to Friday were defined as weekdays; Monday to Friday 8:00-17:00 were defined as daytime of weekdays; Monday to Friday 17:01-07:59 on next day were defined as nights of weekdays; unconventional working time were defined as weekend and nights of weekdays. Good outcome was defined as mRS 0-2 at 3 months. Univariate analyses of baseline and prognostic variables in group of weekend and weekdays, nights of weekdays and daytime of weekdays, unconventional working time and daytime of weekdays were performed. Binary logistic regression was used to investigate whether weekend, nights of weekdays and unconventional working time were independent predicting factors of outcome after intravenous thrombolysis, respectively. RESULTS: There was no difference in 7-day mortality, 3-month mortality and good outcome at 3-month between weekend group and weekdays group, nights of weekdays group and daytime of weekdays group, unconventional working time group and daytime of weekdays group (all P>0.05). Binary logistic regression results showed that weekends, nights of weekdays and unconventional working time were not independent predicting factors for outcome after intravenous thrombolysis (all P>0.05). CONCLUSIONS: The working time has not affected the outcomes of patients with ischemic stroke undergoing intravenous thrombolysis in studied hospitals of Zhejiang province.

Overactive bladder symptom severity, bother, help-seeking behavior, and quality of life in patients with type 2 diabetes: a path analysis.

BACKGROUND: This study aimed to investigate the relationships among overactive bladder (OAB) symptom severity, bother, help-seeking behavior, and quality of life (QOL) in patients with type 2 diabetes. METHODS: A total of 127 diabetic patients, aged at least 18 years, with overactive bladder from a hospital in Shandong Province, China, were recruited for this study. Symptom severity, bother, and quality of life were assessed using the Overactive Bladder Symptom Score (OABSS), Patient Perception of Bladder Condition (PPBC), and Overactive Bladder Questionnaire Short Form (OAB-q SF), respectively. Help-seeking behavior was assessed by asking patients whether they consulted health care professionals or received treatment for their bladder problems. A two-step path analysis was performed to analyze the data. RESULTS: OAB symptom severity was directly associated with lower levels of QOL, and the strength of this association was no longer significant when taking bother and help-seeking behavior into account. Bother increased with OAB symptom severity, and patients with bothersome OAB tended to have lower levels of QOL. Moreover, bother increased help-seeking behavior; however, patients who sought help tended to have lower levels of QOL. CONCLUSIONS: Our findings highlight the role of bother and help-seeking behavior in the relationship between OAB symptom severity and QOL. To improve a patient's QOL, health care providers should focus not only on symptom bother but also on dysfunctional help-seeking patterns.
