Supportive care needs of patients who had a stroke: a scoping review protocol.

INTRODUCTION: Incidences of stroke are on the rise and approximately 80 million stroke survivors worldwide live with disabilities. Supportive care needs of stroke survivors are not adequately defined, and the assessment tools to help care service providers identify these needs are unclear. The overall aim of this scoping review will be to map the supportive care needs of stroke survivors against the Supportive Care Needs Framework. METHODS AND ANALYSIS: This scoping review will be conducted following Arksey and O'Malley's methodological framework and Joanna Briggs Institute (JBI) updated methodological guidance for scoping review. This review will mainly use Arksey and O'Malley's methodological framework as the basic framework. The review will also follow JBI's updated methodological guidance for scoping reviews to optimise the review. For the search strategy, the three-step method recommended by the JBI will be used in the study. The review will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews. Six English databases, including PubMed, CINAHL, Web of Science, Embase, Cochrane Library and PsycInfo, and four Chinese databases, including CNKI, Wanfang, VIP and China Biomedical Literature Database will be systematically searched from inception to the present. Studies published in English and Chinese will be included. ETHICS AND DISSEMINATION: Ethical approval is not required as this scoping review does not involve human participants. The findings shall be disseminated at scientific conferences and published in a peer-reviewed journal.

Effectiveness of acceptance and commitment therapy in patients who had a stroke: a systematic review protocol.

INTRODUCTION: Stroke is a common chronic disease with high rates of morbidity and disability and a great burden on patients. As a result, it affects daily activities of patients and causes negative emotions, which seriously affect their quality of life. As a new type of cognitive-behavioural therapy, acceptance and commitment therapy (ACT) may be useful to improve the mental health of patients who had a stroke. This study aimed to systematically evaluate the intervention effect of ACT in patients who had a stroke, which may provide further clinical evidence. METHODS AND ANALYSIS: A systematic search of databases, including CNKI, WanFang Data, VIP, CBM, PubMed, Embase, Cochrane Library, CINAHL and APA PsycArticles, will be conducted from their inception to 31 October 2022. All randomised controlled trials, quasi-experiments and case studies relevant to ACT will be included in English and Chinese. Two independent reviewers will conduct the review, with data extraction and quality evaluation. Review Manager V.5.4 will be used to assess the risk of bias and meta-analysis. ETHICS AND DISSEMINATION: This systematic review does not require formal ethical approval, because all data will be analysed anonymously. The results will provide an overall review and evidence of the efficacy of ACT in patients who had a stroke. These findings will be disseminated through peer-reviewed publications. PROSPERO REGISTRATION NUMBER: CRD42022355629.

[Assessment of the Spatial-temporal Distribution Characteristics and Main Affecting Factors of Chromophoric Dissolved Organic Matter in Spring and Summer at the Changjiang Estuary and Adjacent Areas].

The composition and distribution characteristics of chromophoric dissolved organic matter(CDOM) of Changjiang Estuary and its adjacent waters in spring (March 2015) and summer (July 2015) were evaluated by excitation-emission matrix spectroscopy (EEMs) in combination with parallel factor(PARAFAC) analysis. Three humic-like components[C1(370/495 nm),C2(330/405 nm),C3(365/440 nm)] and one protein-like component[C4(295/345 nm)] were identified. The distribution patterns of the four components in spring and summer were almost the same, showing a decreasing trend from Changjiang Estuary to adjacent waters. In spring, the high value areas of three humic-like components were located inside of Changjiang Estuary, and the high value areas of the protein-like component were located in the South Passage of Changjiang Estuary. In the surface layer, the CDOM was mainly from terrestrial input and human activities; the influence of terrestrial weakened in the middle layer because of the lower fluorescence intensity values; and in the bottom layer the fluorescence values were higher than those in the middle layer, which was caused by sediment resuspension. There were high value areas in the Daishan Island, which were related to human activities. In summer, the high value areas of CDOM were almost the same as those in spring, and all layers had similar fluorescence intensity values, which indicated that they were mixed evenly. CDOM in spring and summer had high humification index (HIX) values in the Changjiang Estuary, whereas for biological index (BIX), its high values appeared in the adjacent waters. Four components (C1-C4), a355 and DOC, TN, TP, DO, Chl-a, Salinity were evaluated by redundancy analysis (RDA), which indicated that C1-C4 and TN, TP were mainly affected by terrestrial input and human activities, and DOC was affected by terrestrial and marine source together. The use of EEMs-PARAFAC in combination with multivariate analysis to parse the composition of CDOM revealed the source of CDOM and main influencing factors in Changjiang Estuary and adjacent waters, and plays an important role in the biogeochemical research of biogenic elements in estuarine waters.

[Distribution Characteristics of Chromophoric Dissolved Organic Matter and Nutrients from the Yellow Sea and Bohai Sea in Autumn].

Water samples were collected from the Yellow and Bohai seas during November 2013 and the chromophoric dissolved organic matter (CDOM) and nutrients concentrations were investigated, including their composition, source and distribution characteristics. CDOM was analyzed by excitation-emission matrix spectroscopy (EEMS) in combination with a parallel factor analysis (PARAFAC). Three terrestrial humic-like substances (C1, C2, and C3) and one protein-like (C4) substances were identified. The three terrestrial humic-like components had a similar horizontal distribution, decreasing from inshore to offshore. The protein-like component, showed higher values for both inshore and offshore areas in the Yellow Sea at the surface layer and the middle layer of the Bohai Sea, while in other layers it had a similar distribution pattern as the terrestrial humic-like components. In the Bohai Sea, the dissolved inorganic nitrogen (DIN) concentration showed a decreasing trend from inshore to offshore areas and the concentration of dissolved inorganic phosphorus (DIP) gradually decreased from the Caofeidian coastal and central areas to other adjacent areas. The dissolved organic nitrogen (DON) showed an increasing from inshore to the central area of the Bohai Sea. DIN and DON were higher in surface layer than in the bottom layer and for DIP this was the opposite in the Bohai Sea. In the Yellow Sea, DON concentrations showed a decreasing trend from inshore to offshore areas. DIN and DIP had higher concentrations at inshore areas in the surface and middle layers, while in the bottom layer they had higher concentrations in offshore areas. The vertical distribution of the DIN and DIP showed higher values in the bottom layer than surface layers and for DON this was the opposite. These results also showed that the concentrations of DIN, DON, and DIP in the Bohai sea were overall higher than the Yellow Sea. A discriminant analysis was performed through redundancy analysis (RAD) of these water quality parameters, including the four fluorescent components, an absorption coefficient (a355), chlorophyll a concentration, conductivity, dissolved oxygen (DO), dissolved organic carbon (DOC), DIN, DON, and DIP. The RDA indicated that the four fluorescent components are mainly affected by terrestrial inputs. DOC was affected by both terrestrial and marine sources but terrestrial inputs were the major contributor. It was also indicated that the DIN concentration was affected by terrestrial inputs in the Bohai Sea area and by both terrestrial and marine sources in the Yellow Sea. DON concentrations were mainly affected by marine sources in the Bohai Sea and terrestrial inputs in the Yellow Sea. DIP concentrations were affected by both terrestrial and marine sources in the studied areas.

[Impact of metabolic syndrome on cardio-cerebral vascular events in pre-hypertensive population].

OBJECTIVE: This study investigated the impact of metabolic syndrome on the development of cardio-cerebral vascular (CVD) events in a pre-hypertensive population. METHODS: The data used in this prospective study was derived from the Kailuan study cohort (n = 101 510). Prehypertension was diagnosed in 29 968 (mean age: 50 ± 9 years and 23 744 males) individuals by the JNC VII criteria and these subjects were further classified into metabolic syndrome positive (MS+, n = 3447) and MS negative (MS-, n = 26 521) groups according to the modified 2004 Chinese Diabetes Society criteria. Subjects were followed up for 38 - 53 (mean 47 ± 5) months and first-ever CVD events were recorded. Baseline anthropometric and laboratory features were obtained by physical examination from June 2006 to October 2007 and the last follow-up day was December 31, 2010. Multivariable Cox proportional hazards regression models were used to analyze the risk factors of first-ever CVD events. RESULTS: There were 354 CVD events during follow up. The incidences of CVD events (1.80% vs. 1.28%) and cerebral infarction (1.10% vs. 0.57%) were significantly higher in the MS+ group than in the MS- group (all P < 0.05). After adjustment for other established CVD risk factors, the hazards ratio was 1.45 (95%CI: 1.10 - 1.92) for total CVD events and 1.84 (95%CI: 1.27 - 2.67) for cerebral infarction events in MS+ group. CONCLUSIONS: In this cohort, metabolic syndrome is linked with increased risk for CVD events.

[Association between preterm low birth weight and maternal cytokine levels of saliva and gingival crevicular fluid].

OBJECTIVE: To examine the hypothesis that periodontitis was one of the sources of inflammation in preterm low birth weight (PLBW) mothers and investigate the relationship between PLBW and inflammatory factors. METHODS: The samples of saliva and gingival crevicular fluid (GCF) were collected from 83 PLBW mothers (PLBW group) and 44 normal birth weight (NBW) mothers (NBW group). The levels of IL-1beta and IL-6 were analyzed by enzyme-linked immunosorbent assay. The concentrations of cytokines in saliva and GCF were compared between the two groups. RESULTS: IL-1beta level in saliva of PLBW group was higher than which of NBW group significantly [(78.32+/-11.81) ng/L vs. (39.66+/-11.89) ng/L, P<0.05]. There was no statistically significant difference on IL-6 level in saliva [(17.45+/-3.13) ng/L vs. (16.28+/-0.66) ng/L], IL-1beta level in GCF [(93.58+/-13.22) ng/L vs. (81.38+/-9.28) ng/L] and IL-6 level in GCF [(15.35+/-0.28) ng/L vs. (14.87+/-0.37) ng/L) between two groups, but those of PLBW group were higher than NBW group. Significant negative correlations existed between gestational age at delivery and probing depth. It was also found significant negative correlations between gestational age at delivery and IL-6 (r=-0.274, P<0.01), between the weight of the new born infants and IL-6 levels in saliva (r=-0.424, P<0.01), IL-1beta level in GCF (r=-0.231, P<0.01). CONCLUSIONS: There was a tendency presenting the higher inflammatory cytokine in GCF and saliva, the shorter gestation period and the lower birth weight. The levels of cytokine in saliva and GCF were higher in PLBW mothers. The correlation may be exist between maternal periodontitis and PLBW.
