Objectives Our study aimed to investigate the relationship between the severity of frailty and the long-term care (LTC) needs of older adults from Chinese communities.Design A cross-sectional study.Setting Three Chinese community health centres. All data were collected by trained researchers through face-to-face collection.Participants We surveyed a total of 540 older residents who aged 60 or older from community in Guangzhou, China.Measures The Chinese version of the Tilburg frailty indicator was used to assess the frailty status of participants. LTC needs was evaluated by Integrated Home Care Services Questionnaire. Using non-adjusted and multivariate adjusted logistic regression analysis to evaluate frailty and LTC needs, then smoothed plots, threshold effect analysis and P for trend were used to further investigate the relationship between them.Results The prevalence of frailty was 45.2% among the 540 older adults enrolled (aged 70.4±8.3 years; 65.7% females). 27% had higher LTC needs, which increased to 65.1% for individuals with frailty. Logistic regression analysis showed that frailty was strongly associated with LTC needs (OR 3.06, 95% CI 2.06 to 4.55, p

In a single UAV-assisted mobile edge computing system, in order to enable the UAV to serve all user devices in a large area, the large area can be divided into a plurality of sub-areas and the UAV can be set to fly between the sub-areas with a fixed route to provide computing services for the user devices. Considering the scarcity of computational resources for user devices and the fact that users outside the coverage area of the UAV may choose to move to the coverage area for task offloading in order to maximize their own utility, the partial offloading problem of user devices can be transformed into the problem of maximizing the utility of each user device. The mixed-strategy game and the submodular game are used to determine the movement probability of user devices and the amount of offloaded data, so as to derive the optimal offloading strategy, and the existence of mixed-strategy Nash equilibrium and pure-strategy Nash equilibrium is proved, respectively. Simulation results show that the proposed scheme can effectively improve the utility of user device compared with classical schemes such as MBO (Binary Offloading Based on Mixed Strategy Game), and its convergence and stability are verified.

In the title compound, C11H8ClN3O4, the dihedral angle between benzene and isoxazole rings is 9.92 (1) °. The nitro group is almost coplanar with the benzene ring with an O—N—C—C torsion angle of 8.4 (3)°. The molecular conformation is stabilized by an intramolecular N—H...O hydrogen bond, closing a six-membered ring.

Abstract Background Pulmonary infection is a frequent complication among stroke patients and adversely affects clinical outcomes, increases the length of hospitalization stay and costs, and aggravates the financial burden of the national medical health system. Early identification and management of high-risk patients are necessary and imperative to reduce the incidence of stroke-associated pneumonia (SAP). Aim The evidence-based practice project evaluated the effectiveness of a standard care bundle intervention in preventing the occurrence of SAP. Methods The project was conducted in a neurology department of a teaching hospital. Given the variation in assessment and management standards, evidence-based practice (EBP) methodology was used to establish a process for quality improvement. A thorough literature search was conducted to identify evidence-based interventions to manage and prevent SAP. Thorough critiques of the literature and synthesis of the evidence were completed. A systematic management flow and care bundle interventions were established. The care bundle included interventions, such as the utilization of tools for SAP risk screening; dysphagia screening and rehabilitation; feeding modification, oral care, airway management, position management, and the nursing techniques of traditional Chinese medicine. Results A significant improvement was observed in preventing SAP in patients in the postimplementation group compared with those in the preimplementation group (14.0% vs. 37.2%, p = 0.025). In addition, significantly lower duration of hospitalization, lower rate of aspiration, and improvements in albumin and oral hygiene were found after the implementation of the care bundle. Conclusions Evidence-based care bundles successfully empower nurses to reduce the incidence of SAP. The management flow of SAP prevention could be promoted to other units of the neurology department in the future. The results of the project reflect positively on the capacity to implement EBP in an acute care setting for stroke. The EBP methodology can be utilized to solve other clinical problems.

Abstract Background Dysphagia is common after stroke. Patients with dysphagia have a higher risk of stroke-associated pneumonia (SAP) and poor outcomes. Early detection of dysphagia is necessary to identify and manage patients at high risk of aspiration. The aim of the study was to assess the impact of the systematic administration of the volume-viscosity swallow test (V-VST) in patients with acute ischaemic stroke. Methods This was a retrospective observational study that enrolled patients with acute ischaemic stroke in two consecutive time periods: pre-V-VST, when the 30-mL water-swallowing test (WST) was systematically administered, and V-VST, when all patients underwent the WST and the V-VST test was systematically administered if the patient failed the WST. Results Two hundred and 42 patients were enrolled. The mean age of the participants was 68.8 ± 10.88 years, 61.2% were male, and the median National Institutes of Health Stroke Scale score was 3 (IQR, 1–6). A total of 147 patients were enrolled during the pre-V-VST period and 95 were enrolled during the V-VST period. There was a significant difference in the occurrence of SAP (21.8% vs. 10.5%, p = 0.024) and the rate of nasogastric tube feeding (25.9% vs. 14.7%, p = 0.040) between the two groups, and no differences were found in the length of hospital stay (p = 0.277) or the total cost of hospitalization (p = 0.846). Conclusions The V-VST was a better clinical screening tool, and it can also provide detailed suggestions regarding dietary modifications to prevent aspiration and SAP.

Abstract Background Gestational diabetes mellitus (GDM) is a risk factor for diabetes mellitus. The 75-g, 2-h oral glucose tolerance test is recommended for mothers with a history of GDM to screen for diabetes in the postnatal period. The aim of this study was to investigate the rate of glucose screening within 6 months postpartum among Chinese mothers with a history of GDM, and to identify its predictors. Methods A prospective cohort study was conducted in a regional teaching hospital in Guangzhou, China, between July 2016 and June 2017. The participants were Chinese mothers (n = 237) who were diagnosed with GDM, were aged 18 years or older with no serious physical or mental disease and had not been diagnosed with type 1 or type 2 diabetes prior to their pregnancy. The revised Chinese version of the Champion’s Health Belief Model Scale and social-demographic and perinatal characteristics factors were collected and used to predict postpartum glucose screening (yes or no). Adjust odds ratio (AOR) and 95% confidence interval (95% CI) were calculated. Results The mean age of the 237 mothers was 32.70 years (range from 22 to 44). Almost half of the mothers (45.6%) were college graduates or higher. Chinese mothers reported a high level of perceived benefits, self-efficacy, and health motivation towards postpartum glucose screening, with a mean score above 3.5. Chinese mothers were more likely to undertake postpartum glucose screening if they were a first-time mother [AOR 2.618 (95% CI: 1.398–4.901)], had a high perceived susceptibility score [AOR 2.173 (95% CI: 1.076–4.389)], a high perceived seriousness score [AOR 1.988 (95%CI: 1.020–3.875)] and high perceived benefits score [AOR 2.978 (95%CI: 1.540–5.759)]. Conclusion The results of this study will lead to better identification of mothers with a history of GDM who may not screen for postpartum glucose abnormality. Health care professionals should be cognizant of issues that may affect postpartum glucose screening among mothers with a history of GDM, including parity, perceived susceptibility, perceived seriousness and perceived benefits.
