To measure the association of leader–member exchange and team–member exchange with nurses' innovative behaviours through social exchange theory.
The field of nursing is actively advocating innovation. Other fields have proven that leader–member exchange and team–member exchange can promote innovative behaviour, but such an association is not clear in nursing.
A cross-sectional study.
A total of 560 nurses were selected from five tertiary hospitals in Henan Province (China) by multistage sampling. Data were collected from a self-report questionnaire. Thirty nurses in the pre-survey were used to verify the validity of the questionnaire. SPSS PROCESS macro was used to verify the association of leader–member exchange and team–member exchange with nurses' innovative behaviours.
Leader–member exchange and team–member exchange were significantly associated with nurses' innovative behaviours, and team–member exchange had a mediating effect on the relationship between leader–member exchange and innovative behaviour.
Leader–member exchange and team–member exchange positively affect nurses' innovative behaviours. Leader–member exchange can promote nurses' innovative behaviours through the mediating role of team–member exchange.
This study indicated that leader–member exchange and team–member exchange should be given more attention in promoting nurses' innovative behaviours. This finding has implications for the promotion of innovative behaviours in nurses. Leaders need to focus on the innovative needs of nurses and offer support. Meanwhile, leadership training programs are necessary for managers to create positive team relationships.

To examine the prevalence and associated factors of chemotherapy-related cognitive impairment (CRCI) in older breast cancer survivors (BCS).
Systematic review.
We searched EMBASE, PubMed, PsychInfo, CINAHL, Cochrance Library, Web of Science, CNKI and SinoMed, without language restrictions, for studies published from the establishment of the database to September 2022.
Two researchers independently examined the full texts, data extraction and quality assessment, and any discrepancies were resolved through discussion with a third reviewer. Quality of evidence was assessed using the Newcastle-Ottawa Scale and the Agency for Healthcare Research and Quality Scale.
The seven included studies showed that the estimated prevalence of CRCI in older BCS ranged from 18.6% to 27% on objective neuropsychological tests and from 7.6% to 49% on subjective cognitive assessments. The areas most affected were attention, memory, executive functioning and processing speed. CRCI was associated with 10 factors in six categories, including sociodemographic (e.g. age, education level), physiological (e.g. sleep disorders, fatigue and comorbidities), psychological (e.g. anxiety, depression), treatment modalities (e.g. chemotherapy cycles, chemotherapy regimens), genetic (e.g. APOE2, APOE4) and lifestyle factor (e.g. physical inactivity).
CRCI is multifactorial and has a relatively high prevalence. However, the results of subjective and objective cognitive examinations were inconsistent, possibly due to variations in tools used to evaluate different definitions of CRCI. Nevertheless, as there are few published studies of older BCS, this conclusion still require verification by well-designed studies in the future.
We found that the prevalence of CRCI in older adults is relatively high and multifactorial, providing evidence for further health care for this population.
