RESUMO

PURPOSE: This study aimed at exploring SDM implementation and its influencing factors, and preferences towards SDM among parents of children with cancer in China. DESIGN AND METHODS: This cross-sectional study recruited 204 participants from 2 grade-A tertiary hospitals in Guangzhou, China. The preferences towards decision-making, the status of SDM were measured by CPS-P and SDM-Q-9. The nurse support were measure by NPST, the needs of parents were measured by Questionnaire for Needs of Parents Whose Children are in PICU, and sociodemographic and disease-related questionnaires were used to investigate general information of children and parents. Descriptive statistics, univariate analysis, and multivariable linear regression were used for data analysis. RESULTS: Of 204 participants, about half of parents (55.4 %) tended to choose SDM, however, 40.2 % of them still show passive attitudes. The mean SDM-Q-9 score was 31.07 ± 8.74, and the result showed that age (ß = 2.480, P<0.05), relapse (ß = 4.407, P<0.01), course of disease (ß = -5.213, P<0.01), relationships with doctors (ß = -4.05, P<0.05), trust in doctors (ß = -2.796, P<0.05), and communication and information support from nurses (ß = 0.651, P<0.01) were the main factors influencing SDM for parents. CONCLUSIONS: Over half of Chinese parents tended to choose SDM, but their real participation in SDM is unsatisfactory. Parents who were older, had good relationships with doctors, trusted in doctors, received more communication and information support from nurses, and whose children had shorter course of disease, suffered relapses, participated in SDM better.

RESUMO

Background: Because routine nursing quality indicators are not suitable to evaluate pediatric oncology nursing care, this study aimed to identify a set of quality indicators for pediatric oncology nursing care in mainland China. Method: This prospective investigation utilized a modified Delphi technique and an analytic hierarchy process. A survey questionnaire was developed using a literature review and semi-structured interviews. Fifteen invited experts evaluated the importance of potential indicators through three rounds of Delphi survey by email in 2018. The importance weight of each indicator was identified through analytic hierarchy process. Results: In the Delphi survey, the average authoritative coefficient was 0.93-0.96 for each round of the inquiry. After three rounds of survey, 29 quality indicators were identified as important nursing outcomes for assessing the quality of pediatric oncology nursing care in mainland China. The importance rating mean score of indicators ranged between 4.67 and 5.00 on a 5-point scale, and the variation coefficient ranged between 0 and 0.19. Expert-assigned indicator importance weight varied between 0.0040 and 0.0870. Conclusion: This study identified an indicator system with 29 nursing-sensitive quality indicators that may represent potential indicator candidates for quality assessment of pediatric oncology nursing practice in mainland China.

RESUMO

BACKGROUND: Childhood cancer survivors (CCSs) are at increased risk of chronic health conditions, which could be controlled with health behaviors. However, the health behaviors and related factors of Chinese CCSs remain unclear. OBJECTIVE: The aims of this study were to examine multiple health behaviors among Chinese CCSs and explore the individual, interpersonal, and home environmental factors affecting health behaviors. METHODS: This cross-sectional study recruited 204 participants from 3 grade-A tertiary hospitals in Guangzhou, China. Participants provided data on health behaviors (smoking, drinking, drug use, screen time, internet addiction, dietary behaviors, physical activity, and sleep behaviors) and their determining factors. Structural equation modeling was used to analyze the data. RESULTS: Chinese CCSs reported low rates of smoking, drinking, and drug use (0%-6.4%), but only 51% of survivors met screen time recommendations, and 24.5% of them had Internet addiction. Few survivors reported frequent soft-drink, sugar, and fast-food intake (2.0 to 7.4%), but many were finicky eaters (55.4%) or seldom drank milk (41.7%). In addition, 67.6% and 47.5% of survivors did not meet physical activity and sleep time recommendations. Childhood cancer survivors' health behaviors were influenced by the individual (age, education level, and time since diagnosis), interpersonal (peer and family support), and home environmental (residential location, parents' educations level, and household income) factors. CONCLUSIONS: There were suboptimal health behaviors among Chinese CCSs. Targeted interventions should consider their individual, interpersonal, and home environmental factors. IMPLICATIONS FOR PRACTICE: Knowledge of health behaviors and related factors of Chinese CCSs would help healthcare professionals develop further interventions to improve their care of this population.

RESUMO

BACKGROUND: The association between iron supplementation and gestational diabetes mellitus (GDM) is still inconclusive, and this association has not been extensively studied in relation to plasma ferritin in the early second trimester. OBJECTIVES: We aimed to prospectively examine the independent and combined associations of plasma ferritin concentrations and iron supplement use with GDM. METHODS: We studied 2117 women from the Tongji Maternal and Child Health Cohort in Wuhan, China. Plasma ferritin around 16 weeks' gestation was measured by ELISA kits and information on iron supplement use was collected by questionnaires. GDM was diagnosed by a 75-g oral-glucose-tolerance test (OGTT) at 24-28 weeks' gestation. A log-Poisson regression model was used to estimate the RR of GDM associated with plasma ferritin and iron supplementation. RESULTS: The median and IQR of plasma ferritin was 52.1 (29.6-89.9) ng/mL, and 863 (40.8%) participants reported use of iron supplements during the second trimester. A total of 219 (10.3%) participants developed GDM. Adjusted RRs (95% CIs) for GDM across increasing quartiles of plasma ferritin were 1.00 (reference), 2.14 (1.37, 3.34), 2.03 (1.30, 3.19), and 2.72 (1.76, 4.21), respectively. After adjustment, supplemental iron ≥60 mg/d during the second trimester was associated with an increased risk of GDM compared with nonusers (RR: 1.37; 95% CI: 1.02, 1.84). CONCLUSIONS: Both elevated plasma ferritin concentrations in the early second trimester and use of ≥60 mg/d of supplemental iron during pregnancy are independently associated with increased risk of GDM. Further clinical trials with precision nutrition approaches considering both baseline iron status and supplement use are needed to evaluate the benefits and risks of iron supplementation during pregnancy.

RESUMO

BACKGROUND & AIMS: Emerging evidence has shown the inverse association between dietary polyphenols intake and type 2 diabetes mellitus risk, however, few studies focus on the prospective effects of polyphenols on gestational diabetes mellitus (GDM). Thus, the aim was to evaluate whether higher polyphenols intake and the intake from fruits and vegetables was correlated to a lower risk of GDM. METHODS: Dietary intake of polyphenols of women with a singleton pregnancy and without any history of diabetes were obtained by a validated food frequency questionnaire from Tongji Maternal and Child Health Cohort study. Oral glucose tolerance tests were conducted at 24-28 weeks to screen for GDM. Logistic regression models were used to evaluate the association between dietary intake of polyphenols, and the results were presented as odds ratios (ORs) with 95% confidence interval (CIs). Generalized linear models were adopted to determine the association of polyphenols intake with blood glucose concentrations, and the results were presented as coefficients (ß) with 95% CIs. RESULTS: 185 (8.3%) of 2231 pregnant women were diagnosed with GDM. The intake of total polyphenols was 319.9 (217.8-427.0) mg/d, and the intake from fruits and vegetables was 201.6 (115.3-281.8) mg/d and 63.2 (41.1-92.7) mg/d, respectively. Compared with the lowest quartile, the adjusted ORs (95% CIs) of GDM risk for women with the highest quartile of total polyphenols and flavonoids intake was 0.55 (0.30, 0.99), and 0.57 (0.32, 0.99). The adjusted ORs (95% CIs) of GDM risk was 0.55 0.51 (0.30, 0.87) (Pfor trend = 0.017) for polyphenols from fruits, 0.58 (0.34, 0.99) (Pfor trend = 0.038) for flavonoids from fruits, and 0.62 (0.38, 1.00) (Pfor trend = 0.065) for anthocyanidins from fruits comparing the highest versus lowest quartile. In addition, each 100 mg increase of total polyphenols and polyphenols from fruits was associated with 0.054 (0.008, 0.096) (P = 0.021) and 0.061 (0.012, 0.109) (P = 0.015) decrease in 2-h post-load blood glucose. No significant association was found between total polyphenols from vegetables intake and the risk of GDM. CONCLUSIONS: Higher dietary intake of total polyphenols and flavonoids and the intake from fruits was associated with lower GDM risk. This study was registered at clinicaltrials.gov as NCT03099837.

RESUMO

OBJECTIVE: To examine the dietary behaviours, physical activity (PA) and quality of life (QoL) of childhood cancer survivors (CCS) in Mainland China and explore the relationships between these behaviours and QoL. METHODS: This cross-sectional study recruited 181 CCS from three Grade-A tertiary hospitals in Guangzhou. Survivors completed questionnaires assessing their dietary behaviours, PA and QoL. RESULTS: Only 2.2%, 7.7% and 2.2% of CCS reported frequent soft drinks, sugar and fast food intake, which were lower compared to CCS in Western studies. Most survivors (72.9%) failed to drink milk daily, and many (54.7%) were picky eating. Sixty percent of CCS reported less moderate-to-vigorous physical activity (MVPA) time than 60 min/day recommended by WHO. Picky eating was significantly associated with lower overall (p < 0.001), physical (p < 0.001) and psychosocial (p < 0.001) QoL. MVPA was significantly positively associated with overall (p < 0.05) and psychosocial (p < 0.01) QoL. CONCLUSIONS: Chinese CCS engaged better dietary behaviours of less soft drinks, sugar and fast food consumption, but many were picky eaters and did not meet milk intake and PA recommendations. Early behavioural interventions aimed at increasing the dietary diversity and MVPA level of this population should be taken to improve their QoL.

RESUMO

BACKGROUND: Catheter-related thrombosis may lead to catheter infections and failure, further deep venous thrombosis, and pulmonary embolism. Recognizing the risk factors for catheter-related thrombosis is extremely important to inform the development of catheter care guidelines. METHODS: Data were collected from a total of 1,532 patients who had undergone venous catheterization, including indwelling catheterization from 19 March 2019 to 30 March 2019 in the Sun Yat-sen Memorial Hospital. The factors for which data were to be collected included the patients' physical characteristics, catheter-related factors, and catheter care-related factors. Logistic regression analysis, the chi-squared test, Fisher's exact test, and the t-test were used to analyze the data. RESULTS: Of the 1,532 patients studied, 28 developed intraductal thrombi, and of the factors analyzed, malignancy, a catheterization history, a history of thrombophilia, surgery during the week before catheterization, the catheterization duration, and anticoagulant therapy were significant risk factors associated with catheter-related thrombosis (all p < 0.05). There were no significant associations between the catheter brand, the number of lumens, the insertion direction, or the factors associated with catheter care and catheter-related thrombosis (all p > 0.05). CONCLUSION: Our study incorporated clear and systematic risk factors associated with catheter-related thrombosis. Malignancy, history of thrombophilia, history of catheterization, surgery during the week before catheterization, and catheterization duration were associated with increased risks of catheter-related thrombosis. Prophylactic anticoagulation was effective for preventing and treating catheter-related thrombosis.

RESUMO

AIMS: To examine the effects of a group-based physical activity intervention on improvement in physical activity and mitigation of symptom distress among pediatric patients with cancer. METHODS: Based on convenience sampling, 57 pediatric patients with cancer admitted to the cancer center were included in the intervention group. The control group included 57 pediatric patients with cancer from two other hospitals matched to the patients in the intervention group by age, sex, and diagnosis. A group-based physical activity program was implemented among the children in the intervention group, whereas the children in the control group received standard care. Physical activity and symptoms were measured using the Children's Leisure Time Activities Study Survey-Chinese and using the Memorial Symptom Assessment Scale 10-18 at baseline and after the 12th exercise session in both the intervention and control groups. RESULTS: The repeated-measures analysis of variance showed that the main intervention effects on the decrease in light-intensity physical activity and increase in moderate-to-vigorous physical activity were significant between the two groups (P < .001). The group-based physical activity intervention could decrease the scores of psychological symptoms (P < .001), Global Distress Index (P < .001), and physical symptoms (P = .01) when comparing the difference between the two groups before and after the intervention. There was no significant difference in the number of symptoms or the total symptom experience score between the two groups. CONCLUSION: These findings suggest that a group-based physical activity intervention can promote physical activity and relieve psychological and physical symptom distress among pediatric patients with cancer.

RESUMO

PURPOSE: To explore how Chinese families cope with children's hospitalization for cancer treatment. DESIGN AND METHODS: A descriptive qualitative inquiry was employed. Semi-structured interview was conducted in four pediatric oncology departments in four hospitals from November 2017 to June 2018. The interviews focused on how families cope with the challenges resulting from their children's hospitalization for cancer treatment. Twenty one parents participated into the study. RESULTS: Four categories related to family coping strategies emerged from the data, including increasing family strength, maintaining optimistic thoughts, seeking external support, and not disclosing the unfavorable information. CONCLUSIONS: Families had adopted multiple coping strategies to handle the challenges caused by children's hospitalization for cancer treatment. The influences of Chinese culture on family coping should be taken into consideration during family-centered interventions development. Further studies could analyze whether the spouse perspectives are independent from one another and whether the coping strategies change as the time of hospitalization. PRACTICE IMPLICATIONS: This study has reminded nurses' to become more concerned about the influences of culture on families' coping strategies during this challenging period. Other nurses in the world could understand how to enhance family coping strategies of Chinese clients.

RESUMO

Phlorotannins are polyphenolic metabolites of marine brown algae that have been shown to possess health-beneficial biological activities. An efficient approach using a combination of high-speed counter-current chromatography (HSCCC) and size exclusion chromatography with a Sephadex LH-20 has been successfully developed for the isolation and purification of a neuroprotective phlorotannin, eckmaxol, from leaves of the marine brown algae, Ecklonia maxima. The phlorotannin of interest, eckmaxol, was isolated with purity >95% by HSCCC using an optimized solvent system composed of n-hexane-ethyl acetate-methanol-water (2:8:3:7, v/v/v/v) after Sephadex LH-20 size exclusion chromatography. This compound was successfully purified in the quantity of 5.2 mg from 0.3 kg of the E. maxima crude organic extract. The structure of eckmaxol was identified and assigned by NMR spectroscopic and mass spectrometric analyses. The purification method developed for eckmaxol will facilitate the further investigation and development of this neuroprotective agent as a drug lead or pharmacological probe. Furthermore, it is suggested that the combination of HSCCC and size exclusion chromatography could be more widely applied for the isolation and purification of phlorotannins from marine algae.

RESUMO

BACKGROUND: Postoperative hyperglycaemia has been shown to have adverse effects on patients after coronary artery bypass grafting surgery (CABG). However, whether glucose variability has an effect on patients' outcomes is still uncertain. The aim of this study is to explore the effects of glucose variability on short-term outcomes in non-diabetic patients undergoing coronary artery bypass grafting. METHODS: This is a retrospective observational study utilising data collected after patients had left the hospital. This study was performed on 137 non-diabetic patients undergoing coronary artery bypass grafting from January 2011 to June 2013. Blood glucose at 72hours post operation was obtained and glucose variability was measured by mean postoperative blood glucose and mean of daily difference (MODD). Short-term outcomes included duration of intensive care unit (ICU) stay, mechanical ventilation time, length of hospital stay, and occurrence of arrhythmia. Patients with mean postoperative blood glucose ≥7.00mmol/L were defined as hyperglycaemic, and patients with MODD ≥1.40mmol/L were considered to be abnormal. Outcome variables were compared between patients in euglycaemic and hyperglycaemic groups, and between patients in normal and abnormal groups. RESULTS: In our study, patients with hyperglycaemia spent more time staying in ICU (p<0.01), and patients with large glucose variability (abnormal MODD) had higher incidences of arrhythmia (23% vs 4.2%, p<0.05). Regression analysis showed that MODD can affect occurrence of arrhythmia (p=0.004) and that mean postoperative blood glucose levels can affect duration of ICU stay (p<0.001). CONCLUSIONS: Patients' postoperative glucose variability after CABG is an important predictor of the negative outcomes regarding duration of ICU stay and occurrence of arrhythmia. Large glucose variability can have negative effects on short-term outcomes in patients.

RESUMO

PURPOSE: The focus of this paper is to identify the unmet family needs during children's hospitalization for cancer treatment. DESIGN AND METHODS: Qualitative interviews were carried out with five fathers and fourteen mothers purposively sampled from four pediatric oncology departments in Mainland China from September 2013 to March 2014. Audiotaped interviews were transcribed verbatim, and data in transcripts were coded and analyzed by qualitative content analysis. RESULTS: The identified unmet family needs pertaining to healthcare service during a child's hospitalization for cancer treatment were unmet need for warm and supportive attitudes; competent care; adequate information; a comfortable environment; and catering support. CONCLUSIONS: The results showed that families with children hospitalized for cancer treatment have a variety of unmet needs related to healthcare service. These identified unmet family needs have already shed light on areas for healthcare service improvement. PRACTICE IMPLICATIONS: This study have reminded nurses' to become more concerned about unmet family needs instead of only focusing on the hospitalized child in clinical settings. Healthcare professionals can assist in promoting family adaptation to children's hospitalization by satisfying their unmet family needs.

RESUMO

We present the genome sequence of Saccharospirillum mangrovi HK-33T, isolated from a mangrove sediment sample in Haikou, China. The complete genome of S. mangrovi HK-33T consisted of a single-circular chromosome with the size of 3,686,911 bp as well as an average G + C content of 57.37%, and contained 3,383 protein-coding genes, 4 operons of 16S-23S-5S rRNA genes, and 52 tRNA genes. Genomic annotation indicated that the genome of S. mangrovi HK-33T had many genes related to oligosaccharide and polysaccharide degradation and utilization of polyhydroxyalkanoate. For nitrogen cycle, genes encoding nitrate and nitrite reductase, glutamate dehydrogenase, glutamate synthase, and glutamine synthetase could be found. For phosphorus cycle, genes related to polyphosphate kinases (ppk1 and ppk2), the high-affinity phosphate-specific transport (Pst) system, and the low-affinity inorganic phosphate transporter (pitA) were predicted. For sulfur cycle, cysteine synthase and type III acyl coenzyme A transferase (dddD) coding genes were searched out. This study provides evidence about carbon, nitrogen, phosphorus, and sulfur metabolic patterns of S. mangrovi HK-33T and broadens our understandings about ecological roles of this bacterium in the mangrove sediment environment.

RESUMO

OBJECTIVES: To examine the relationship between poor sleep quality during pregnancy and the risk of gestational diabetes mellitus (GDM). METHODS: A total of 4066 singleton pregnant women from the Tongji Maternal and Child Health Cohort (TMCHC) without overt diabetes before pregnancy were analyzed. Sleep quality and duration during early pregnancy were self-reported by enrolled women at their first antenatal care visit before 16 weeks of gestation. Gestational diabetes mellitus (GDM) was assessed with a 75-g, 2-h oral glucose tolerance test at 24-28 weeks of gestation. Information about self-reported sleep quality and duration in mid-pregnancy were also collected at this time. Odds ratios (OR) and 95% CIs were calculated by multivariable logistic regression models, and adjusted for potential confounders to estimate the effect of poor sleep quality and the interaction between sleep quality and duration on the development of GDM. Stratified analyses were performed according to age, parity, family history of diabetes and napping. RESULTS: A total of 335 (8.2%) participants were diagnosed with GDM. Poor sleep quality was reported in 259 (6.4%) women during early pregnancy and 248 (6.1%) in mid-pregnancy. The risk of GDM was increased in women with poor sleep quality during early pregnancy (OR 1.77, 95% CI 1.20-2.61). No association was found between poor sleep quality during mid-pregnancy and the risk of GDM. The risk of GDM was highest in women with poor sleep and longer nighttime sleep duration during early pregnancy (OR 2.27, 95% CI 1.20-4.29) when compared with those who reported good sleep and 7.0-8.5 h of sleep duration per night. Stratified analysis found that the association between poor sleep quality in early pregnancy and the risk of GDM was stronger among women aged ≥30 years (OR 2.35, 95% CI 1.35-4.09) and those with a family history of diabetes (OR 4.02, 95% CI 1.54-10.48). CONCLUSIONS: Poor sleep quality during early pregnancy was associated with an increased risk of GDM. Screening for and treating sleep problems in early pregnancy could potentially reduce the risk of GDM.

RESUMO

Alzheimer's disease is a progressive neurodegenerative disorder that mainly affects the elderly. Soluble ß-amyloid oligomer, which can induce neurotoxicity, is generally regarded as the main neurotoxin in Alzheimer's disease. Here we report that eckmaxol, a phlorotannin extracted from the brown alga Ecklonia maxima, could produce neuroprotective effects in SH-SY5Y cells. Eckmaxol effectively prevented but did not rescue ß-amyloid oligomer-induced neuronal apoptosis and increase of intracellular reactive oxygen species. Eckmaxol also significantly reversed the decreased expression of phospho-Ser9-glycogen synthase kinase 3ß and increased expression of phospho-extracellular signal-regulated kinase, which was induced by Aß oligomer. Moreover, both glycogen synthase kinase 3ß and mitogen activated protein kinase inhibitors produced neuroprotective effects in SH-SY5Y cells. Furthermore, eckmaxol showed favorable interaction in the ATP binding site of glycogen synthase kinase 3ß and mitogen activated protein kinase. These results suggested that eckmaxol might produce neuroprotective effects via concurrent inhibition of glycogen synthase kinase 3ß and extracellular signal-regulated kinase pathways, possibly via directly acting on glycogen synthase kinase 3ß and mitogen activated protein kinase. Based on the central role that ß-amyloid oligomers play in the pathogenesis of Alzheimer's disease and the high annual production of Ecklonia maxima for alginate and other nutritional ingredients, this report represents a new candidate for the treatment of Alzheimer's disease, and also expands the potential application of Ecklonia maxima and its constituents in the field of pharmacology.

RESUMO

OBJECTIVES: To examine the relationship between prenatal nitrogen dioxide (NO2) exposure and foetal growth in a prospective cohort of 1001 Chinese women. METHODS: The maternal NO2 exposure levels were estimated using land-use regression models based on home address. The biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), femur length (FL) and estimated foetal weight (EFW) were evaluated via ultrasonography. The multiple linear regression model was used to adjust for confounders, and the mixed-effect model was used to assess longitudinal effect. RESULTS: With a 10 µg/m3 increase in NO2 exposure, the BPD, HC, AC, FL and EFW in the second trimester decreased by 0.40 mm (95% CI -0.56 to -0.24), 1.07 mm (95% CI -1.60 to -0.54), 1.02 mm (95% CI -1.57 to -0.48), 0.24 mm (95% CI -0.37 to -0.12) and 7.84 g (95% CI -11.59 to -4.08), respectively; the BPD and HC in the third trimester decreased by 0.26 mm (95% CI -0.50 to -0.02) and 0.71 mm (95% CI -1.37 to -0.06), respectively. The longitudinal analyses showed inverse associations of NO2 exposure with BPD, HC, AC and FL (all p<0.05). The stratified analyses showed that the effects of NO2 on the HC, FL and EFW in the second trimester were stronger among female babies and that the effect of NO2 on EFW in the third trimester was stronger among smoking mothers (all p<0.05). CONCLUSIONS: In this prospective study of Chinese women, maternal NO2 exposure was inversely associated with foetal growth, and the association was stronger among female babies and smoking mothers.

RESUMO

BACKGROUND: Families with children hospitalized for cancer treatment experience multiple, serious challenges. Family coping is a crucial moderator between family stress and family adaptation. A newly developed instrument, the Hospitalization Coping Scale (HCS), measures the effectiveness of family coping during a child's hospitalization. OBJECTIVE: The aims of this study were to revise and validate the psychometric properties of the HCS for families with children hospitalized for cancer treatment in pediatric oncology departments in Mainland China. METHODS: Psychometric properties of the HCS were examined among 253 families with children hospitalized in pediatric oncology departments in 4 hospitals. Reliability, construct validity, known-group validity, and concurrent validity of the revised HCS were examined. RESULTS: The revised 15-item HCS contains 3 renamed factors: maintaining mental stability, mutual support for child care, and seeking support from external systems. Cronbach's α coefficients for the total and 3 factors were .87, .78, .83, and .79, respectively. The revised scale demonstrated sound known-group validity and concurrent validity. CONCLUSIONS: The revised 15-item HCS is a reliable and valid instrument to measure coping effectiveness of families with children hospitalized for cancer treatment. IMPLICATIONS FOR PRACTICE: The HCS can be used by pediatric oncology nurses to assess the effectiveness of family coping during a hospitalization of their child with cancer and may help pediatric oncology nurses to develop and implement realistic support strategies based on assessments of family coping effectiveness.
