Chinese and Belgian pediatricians' perspectives toward pediatric palliative care: an online survey.

BACKGROUND: As pediatricians play a vital role in pediatric palliative care (PPC), understanding their perspectives toward PPC is important. PPC is established for a long time in Belgium, but has a shorter tradition in China, although it is growing in the last decade. Sampling and comparing the perspectives of these pediatricians could be insightful for both countries. Therefore, we sampled and compared perspectives of pediatricians in China and Belgium toward PPC, and explored factors influencing their perspectives. METHODS: We conducted a cross-sectional online survey using the validated Pediatric Palliative Care Attitude Scale (PPCAS). Over a five-month period, we recruited pediatricians practicing in China (C) and Flanders (F), Belgium. Convenience sampling and snowballing were used. We analyzed data with descriptive statistics, and evaluated group differences with univariate, multivariate and correlation tests. RESULTS: 440 complete surveys were analyzed (F: 115; C: 325). Pediatricians in both regions had limited PPC experience (F: 2.92 ± 0.94; C: 2.76 ± 0.92). Compared to Flemish pediatricians, Chinese pediatricians perceived receiving less unit support (F: 3.42 ± 0.86; C: 2.80 ± 0.89); perceived PPC less important (F: 4.70 ± 0.79; C: 4.18 ± 0.94); and faced more personal obstacles while practicing PPC (F: 3.50 ± 0.76; C: 2.25 ± 0.58). Also, select socio-demographic characteristics (e.g., experiences caring for children with life-threatening condition and providing PPC) influenced pediatricians' perspectives. Correlational analyses revealed that pediatricians' PPC experiences significantly correlated with perceived unit support (ρF = 0.454; ρC=0.661). CONCLUSIONS: Chinese pediatricians faced more barriers in practicing PPC. Expanding PPC experiences can influence pediatricians' perspectives positively, which may be beneficial for the child and their family.

Physicians' attitudes and experiences about withholding/withdrawing life-sustaining treatments in pediatrics: a systematic review of quantitative evidence.

BACKGROUND: One of the most important and ethically challenging decisions made for children with life-limiting conditions is withholding/withdrawing life-sustaining treatments (LST). As important (co-)decision-makers in this process, physicians are expected to have deeply and broadly developed views. However, their attitudes and experiences in this area remain difficult to understand because of the diversity of the studies. Hence, the aim of this paper is to describe physicians' attitudes and experiences about withholding/withdrawing LST in pediatrics and to identify the influencing factors. METHODS: We systematically searched Pubmed, Cinahl®, Embase®, Scopus®, and Web of Science™ in early 2021 and updated the search results in late 2021. Eligible articles were published in English, reported on investigations of physicians' attitudes and experiences about withholding/withdrawing LST for children, and were quantitative. RESULTS: In 23 included articles, overall, physicians stated that withholding/withdrawing LST can be ethically legitimate for children with life-limiting conditions. Physicians tended to follow parents' and parents-patient's wishes about withholding/withdrawing or continuing LST when they specified treatment preferences. Although most physicians agreed to share decision-making with parents and/or children, they nonetheless reported experiencing both negative and positive feelings during the decision-making process. Moderating factors were identified, including barriers to and facilitators of withholding/withdrawing LST. In general, there was only a limited number of quantitative studies to support the hypothesis that some factors can influence physicians' attitudes and experiences toward LST. CONCLUSION: Overall, physicians agreed to withhold/withdraw LST in dying patients, followed parent-patients' wishes, and involved them in decision-making. Barriers and facilitators relevant to the decision-making regarding withholding/withdrawing LST were identified. Future studies should explore children's involvement in decision-making and consider barriers that hinder implementation of decisions about withholding/withdrawing LST.

Effects of Hydrogen Peroxide-Induced Oxidative Stress on Intestinal Morphology, Redox Status, and Related Molecules in Squabs.

The purpose of this study was to evaluate the potential effect of oxidative stress on the intestine of squabs, and to explore the molecular mechanisms. A total of 360 1-day-old squabs were divided evenly into five different groups (n = 72/group): control, negative control, low, medium, and high dose groups. On the 3rd, 5th, and 7th days, squabs in the control group were not effectively treated and the negative control group were intraperitoneally injected with normal saline, whereas the H2O2 group was injected with H2O2 of 2.0, 2.5, and 3.0 mmol/kg BW respectively. On the 21st day, the serum and duodenum were collected for further analysis. The results indicated that, compared with the control group, H2O2 caused squabs weight loss and intestinal morphology damage, and these effects were enhanced with an increase in dose. Further examination revealed that the contents of oxidative stress markers in both the serum and duodenum of the H2O2 group were significantly enhanced as the dose was increased. In addition, H2O2 exposure also resulted in the lower mRNA expression of Occludin, ZO-1, Beclin1, Atg5, and Caspase-3, but the expression of Claudin2 and Bcl-2 was decreased in comparison to the control group. These findings suggested that duodenal oxidative damage was accompanied by weight loss, changes in intestinal morphology, redox status imbalance, apoptosis as well as autophagy of intestinal cells, with, effects of 3.0 mmol/kg BW of H2O2 being the most severe.

Effect of tea polyphenols supplement on growth performance, antioxidation, and gut microbiota in squabs.

Early life nutritional supplementation can significantly improve pigeon health. Both the nutritional crops of parental pigeons and the intestinal development of squabs play key roles in the growth rate of squabs. Tea polyphenols (TPs), as natural plant extracts, exhibit potential biological activities. However, the impact of TPs on the intestinal function of squabs is not known. This study evaluated the effects of TPs on growth performance, immunity, antioxidation, and intestinal function in squabs. A total of 432 young pigeons (1 day old) were divided into four groups: a control group (fed a basic diet) and three treatment groups (low, medium, and high dose groups; 100, 200, and 400 mg/kg TPs, respectively). On the 28th day, samples of serum, mucosal tissue, and digests from the ileum of squabs were collected for analysis. The results revealed that TP supplementation significantly reduced the feed-to-meat ratio and improved the feed utilization rate and serum biochemical indices in squabs. Additionally, it enhanced the intestinal barrier function of birds by promoting intestinal development and integrity of tight junctions and regulating digestive enzyme activities and intestinal flora. Mechanistically, TPs activated the Nrf2-ARE signaling pathway, which may be associated with improved antioxidant and immune responses, correlating with an increased abundance of Candida arthritis and Corynebacterium in the ileum.

Development of the Simplified Chinese version of neonatal palliative care attitude scale.

Background: The provision of palliative care for neonates who are not expected to survive has been slow in mainland China, and this model of care remains in its early stages. Evaluating nurses' attitudes toward neonatal palliative care (NPC) has the potential to provide valuable insight into barriers impeding NPC implementation. This study aimed to translate and adapt the traditional Chinese version of the Neonatal Palliative Care Attitude Scale (NiPCAS) into Simplified Chinese to assess its psychometric properties. Methods: The NiPCAS is a valid and reliable instrument to measure nurses' attitudes for evidence-based practice. To date, the scale has not been used largely in mainland China. With translation and cultural adaptation, the traditional Chinese version of the NiPCAS was developed into a Simplified Chinese version. Its reliability was tested using internal consistency and test-retest reliability, and its validity was measured using the content validity index and exploratory factor analysis. Results: A total of 595 neonatal nurses from mainland China were recruited. Twenty-six items in the scale were translated into Simplified Chinese. The scale demonstrated excellent reliability with a Cronbach's α coefficient of 0.87 and a test-retest reliability of 0.88. To support the Simplified Chinese version of NiPCAS, the scale content validity score was 0.98, and the exploratory factor analysis revealed five factors representing the conceptual dimensions of the scale. Conclusion: This study demonstrated the psychometric properties of the Simplified Chinese version of NiPCAS, validated its use as a viable tool for measuring neonatal nurses' attitudes toward NPC, and identified facilitators and barriers to NPC adoption. Our findings suggested supported clinical application in the context of mainland China. A confirmatory factor-analysis approach with a different sample of neonatal nurses is required for further testing of the instrument in the future.

Facilitators and Barriers Affecting Implementation of Neonatal Palliative Care by Nurses in Mainland China.

Neonatal nurses in mainland China encounter various challenges when it comes to delivering palliative care to neonates. The aim of this study was to determine the barriers and facilitators of neonatal nurses' attitudes to palliative care for neonates in mainland China. A simplified Chinese version of the Neonatal Palliative Care Attitude Scale was piloted, administered, and analyzed using survey methods. Nurses in neonatal intensive care units in mainland China regardless of experience in the field were invited to take part in. Over a five-month period in 2019, we surveyed neonatal nurses from 40 hospitals in five provinces of China. The response rate was 92.5% (N = 550). This study identified eight facilitators and four barriers to neonatal palliative care implementation. In terms of nurses' attitudes on providing palliative care, younger and older nurses were more positive, whereas middle-aged nurses were less so. Nurses' emotional wellbeing was rarely impacted by neonatal death. They considered neonatal palliative care, particularly pain management, to be just as important as curative treatment. Parents were invited to participate in decision-making by nurses. Nurses reported having access to professional counseling and talking about their concerns with other healthcare professionals. The following barriers to neonatal palliative care were identified in this study that were not observed in the original English version scale research in 2009: a lack of clinicians, time, clinical skills, systematic education, neonatal palliative care experience, and social acceptance. Future research is required to investigate each barrier in order to improve the implementation of neonatal palliative care in mainland China.

Physician decision-making process about withholding/withdrawing life-sustaining treatments in paediatric patients: a systematic review of qualitative evidence.

BACKGROUND: With paediatric patients, deciding whether to withhold/withdraw life-sustaining treatments (LST) at the end of life is difficult and ethically sensitive. Little is understood about how and why physicians decide on withholding/withdrawing LST at the end of life in paediatric patients. In this study, we aimed to synthesise results from the literature on physicians' perceptions about decision-making when dealing with withholding/withdrawing life-sustaining treatments in paediatric patients. METHODS: We conducted a systematic review of empirical qualitative studies. Five electronic databases (Pubmed, Cinahl®, Embase®, Scopus®, Web of Science™) were exhaustively searched in order to identify articles published in English from inception through March 17, 2021. Analysis and synthesis were guided by the Qualitative Analysis Guide of Leuven. RESULTS: Thirty publications met our criteria and were included for analysis. Overall, we found that physicians agreed to involve parents, and to a lesser extent, children in the decision-making process about withholding/withdrawing LST. Our analysis to identify conceptual schemes revealed that physicians divided their decision-making into three stages: (1) early preparation via advance care planning, (2) information giving and receiving, and (3) arriving at the final decision. Physicians considered advocating for the best interests of the child and of the parents as their major focus. We also identified moderating factors of decision-making, such as facilitators and barriers, specifically those related to physicians and parents that influenced physicians' decision-making. CONCLUSIONS: By focusing on stakeholders, structure of the decision-making process, ethical values, and influencing factors, our analysis showed that physicians generally agreed to share the decision-making with parents and the child, especially for adolescents. Further research is required to better understand how to minimise the negative impact of barriers on the decision-making process (e.g., difficult involvement of children, lack of paediatric palliative care expertise, conflict with parents).

Association between workplace bullying and nurses' professional quality of life: The mediating role of resilience.

AIM: We aim to determine workplace bullying in relation to the professional quality of life of nurses and the mediating role of resilience between workplace bullying and the professional quality of life. BACKGROUND: Workplace bullying is an increasingly serious problem worldwide and deleteriously affects the occupational health and quality of life of nurses. However, it has not attracted adequate managerial attention. METHOD: A cross-sectional study was conducted using a sample of 493 clinical nurses from two tertiary grade A hospitals in Guangzhou, China. Data were collected through an online questionnaire survey in July 2020 and analysed with structural equation modelling. RESULTS: Workplace bullying had negative and direct effects on the professional quality of life of nurses. Resilience mediated the relationship between workplace bullying and the professional quality of life. CONCLUSION: Resilience is a protective factor that helps nurses cope with workplace bullying. Managers can improve the professional quality of life of nurses by reducing workplace bullying and strengthening the resilience of nurses. IMPLICATIONS FOR NURSING MANAGEMENT: Managers must take measures to prevent the workplace bullying of nurses. In addition, nurse supervisors should pay attention to the resilience of nurses and strengthen resilience training to help nurses withstand the pressure of workplace bullying and improve their professional quality of life.

Effectiveness of electroacupuncture for female stress urinary incontinence: a systematic review and Meta-analysis.

OBJECTIVE: To evaluate the effectiveness of electroacupuncture (EA) for female stress urinary incontinence (SUI). METHODS: We searched 12 databases electronically from inception to November 2018 without language restrictions. We included randomized controlled trials (RCTs) involving women with SUI, but excludd other types of urinary incontinence or studies that were not RCTs. Two independent reviewers extracted study characteristics, with disagreements resolved by consensus. Data were pooled and expressed as mean difference (MD) for continuous outcomes and relative risk (RR) for dichotomous outcomes, with 95% confidence intervals (CI). This study was registered with the International Prospective Register of Systematic Reviews (number CRD42018089734). RESULTS: We found very low to high level evidence that EA improved the effective rate (RR = 2.03, 95%CI: 1.40, 2.95; P = 0.0002) and reduced urine leakage as measured by the 1-hour pad test (MD = 3.33, 95%CI: 0.89, 5.77; P = 0.008), International Consultation on Incontinence Questionnaire Short Form score (MD = 3.14, 95%CI: 2.42, 3.85; P < 0.00001), and 72-hour incontinence episodes (MD = 1.17, 95%CI: 0.56, 1.78; P = 0.0002) compared with sham electroacupuncture (SA), pelvic floor muscle training, and medication. CONCLUSION: The effectiveness and safety of EA for key outcomes for women with SUI are statistically significantly better than those of SA, but most available evidence is very low or low quality. More well-designed RCTs are needed to confirm these findings.

Acupuncture in improving endometrial receptivity: a systematic review and meta-analysis.

BACKGROUND: This systematic review aimed at summarizing and evaluating the evidence of randomized controlled trials (RCTs) using acupuncture to improve endometrial receptivity (ER). METHODS: We searched 12 databases electronically through August 2018 without language restrictions. We included RCTs of women of infertility due to low ER, and excluded infertility caused by other reasons or non-RCTs. Two independent reviewers extracted the characteristics of studies and resolved the differences through consensus. Data were pooled and expressed as standard mean difference (SMD) or mean difference (MD) for continuous outcomes and risk ratio (RR) for dichotomous outcomes, with 95% confidence interval (CI). RESULTS: We found very low to moderate level of evidence that acupuncture may improve pregnancy rate (RR = 1.23 95%CI[1.13, 1.34] P < 0.00001) and embryo transfer rate (RR = 2.04 95%CI[1.13, 3.70] P = 0.02), increase trilinear endometrium (RR = 1.47 95%CI [1.27, 1.70] P < 0.00001), thicken endometrium (SMD = 0.41 95% CI [0.11, 0.72] P = 0.008), reduce resistive index (RI) (MD = -0.08 95% CI [- 0.15, - 0.02] P = 0.01), pulse index (PI) (SMD = -2.39 95% CI [- 3.85, - 0.93] P = 0.001) and peak systolic velocity/ end-diastolic blood velocity (S/D) (SMD = -0.60 95% CI [- 0.89, - 0.30] P < 0.0001), compared with medication, sham acupuncture or physiotherapy. Acupuncture was statistically significant as a treatment approach. CONCLUSION: The efficacy and safety of acupuncture on key outcomes in women with low ER is statistically significant, but the level of most evidence was very low or low. More large-scale, long-term RCTs with rigorous methodologies are needed.

Electroacupuncture for Postoperative Urinary Retention: A Systematic Review and Meta-Analysis.

BACKGROUND: This systematic review aimed at summarizing and evaluating the evidence from randomized controlled trials (RCTs) which used electroacupuncture (EA) to treat postoperative urinary retention (PUR). METHODS: We searched thirteen databases electronically through April 2018 without language restrictions. We included RCTs of women with PUR; other types of urinary retention or not-RCTs were excluded. Two independent reviewers extracted studies' characteristics, and disagreements were resolved by consensus. Data were pooled and expressed as standard mean difference (SMD) for continuous outcomes and odds ratio (OR) for dichotomous outcomes, with 95% confidence interval (CI). RESULTS: We found very low to moderate level of evidence that effects of less than or equal to a week were statistically significant: therapeutic effect improved (OR=4.21; 95%CI [3.04, 5.83]; P<0.00001), residual urine volume decreased (SMD=-13.24; 95%CI [-15.70, -10.78]; P<0.00001), bladder capacity increased (SMD=0.56; 95%CI [0.30, 0.83]; P<0.0001), and urinary flow rate improved (SMD=0.91; 95%CI [0.64, 1.18]; P<0.00001). Effect over a week was statistically significant as well. Therapeutic effect improved (OR=8.29; 95%CI [2.91, 24.25]; P<0.0001), residual urine volume decreased (SMD=-1.78; 95%CI [-2.66, -0.89]; P<0.0001), bladder capacity (SMD=0.92; 95%CI [0.61, 1.23]; P<0.00001) and urinary flow rate (SMD=1.69; 95%CI [0.59, 2.79]; P=0.003) increased, and first urination after surgery was earlier (SMD=-0.92; 95%CI [-1.37, -0.46]; P<0.0001), compared with physical exercise, medication, or no treatment. CONCLUSION: The efficacy and safety of EA on key outcomes in women with PUR are statistically significant, but the level of most evidence was very low or low. More large-scale, long-term RCTs with rigorous methodological quality are needed.
