Brain science accelerates the study of intelligence and behavior, contributes fundamental insights into human cognition, and offers prospective treatments for brain disease. Faced with the challenges posed by imaging technologies and deep learning computational models, big data and high-performance computing (HPC) play essential roles in studying brain function, brain diseases, and large-scale brain models or connectomes. We review the driving forces behind big data and HPC methods applied to brain science, including deep learning, powerful data analysis capabilities, and computational performance solutions, each of which can be used to improve diagnostic accuracy and research output. This work reinforces predictions that big data and HPC will continue to improve brain science by making ultrahigh-performance analysis possible, by improving data standardization and sharing, and by providing new neuromorphic insights.

Objective:To systematically evaluate and integrate qualitative research on the real experience of moral distress among Intensive Care Unit (ICU) nurses.Methods:Qualitative researches on the moral distress of ICU nurses were searched through computers in PubMed, Cochrane Library, Web of Science, Embase, China National Knowledge Infrastructure, WanFang Database, VIP, and China Biology Medicine disc. The search period was from the establishment of the database to April 15, 2023. The quality evaluation of the included studies was conducted using the quality evaluation criteria for qualitative research of the Joanna Briggs Institute Evidence-Based Health Care Center (2017) in Australian. The aggregation integration method was used to integrate the results.Results:A total of 13 articles were included, and 42 main results were extracted and categorized into 9 categories. Three integrated results were synthesized, namely the generation and experience of moral distress among ICU nurses, the impact of moral distress on ICU nurses, and the coping styles to moral distress among ICU nurses.Conclusions:Nursing managers should attach importance to the moral distress experience of ICU nurses, reduce the negative impact of moral distress on ICU nurses, and enhance their moral resilience.

Objective:To evaluate the methodological quality and measurement characteristics of children's needs assessment tools.Methods:Literature on children's needs assessment tools was searched in Cochrane Library, PubMed, Embase, Web of Science, CINAHL, China National Knowledge Infrastructure (CNKI), WanFang Data, VIP, and China Biology Medicine disc. The search period was from database establishment to April 2, 2023. The Consensus-based Standards for the Selection of Health Measurement Instruments (COSMIN) guideline was used to evaluate the methodological quality and measurement characteristics of assessment tools, and integrate the evaluation results to form recommendations.Results:Six studies were included in total. The recommended opinions for the two evaluation tools (Needs of Children Questionnaire and Male Adolescent Health Needs-Assessment Scale) were A level. The recommended opinions for the four evaluation tools were B level. The Male Adolescent Health Needs-Assessment Scale had high cultural specificity.Conclusions:The evidence quality of the Needs of Children Questionnaire is relatively high and can be temporarily recommended for use, but other measurement characteristics still need further verification.

OBJECTIVE:
To improve the surgical outcome of pituitary adenomas by identifying and preserving the pituitary stalk and the gland during surgery.
METHODS:
From October 2010 to September 2012, the author from the Department of Neurosurgery of Xiangya Hospital, Central South University operated on 51 patients with pituitary adenoma. During the operations, we carefully identified the normal adenohypophysis, pituitary stalk, neurohypophysis and the abnormal tissues either by direct observation or by medical images, aiming to excise the tumor thoroughly, protect the pituitary function and reduce the postoperative complications.
RESULTS:
Totally 37 patients (72.5%, 37/51) had total resection of the tumor, 12 (23.5%, 12/51) had subtotal tumor resection and the other 2 had major removal. The gland and the pituitary stalk were well identified and reserved. Detection of hormone content proved that the operation had little effect on the free triiodothyronine (FT3) and adrenocorticotropic hormone (ACTH), while for free tetraiodothyronine (FT4) and thyroid stimulating hormone (TSH) and postoperative followup significant alleviation was found. There was no significant fluctuation for the testosterone in the men preoperatively and postoperatively (all the above results were obtained without hormone replacement therapy). The main postoperative complications were as follows: temporary diabetes insipidus in 5 patients (9.8%, 5/51); electrolyte disorder (the appearance of hyponatremia) in 17 (33.3%, 17/51); and cerebrospinal fluid rhinorrhea and postoperative intracranial infection in 1 (2%, 1/51). No one died during the perioperation period.
CONCLUSION
Microscopic transsphenoidal surgery is effective for pituitary adenomas including tumors violating the cavernous sinus. Accurate identification of the pituitary stalk, the gland and the abnormal tissue during the microscopic transsphenoidal operation plays a critical role in preserving the pituitary function and promoting postoperative rehabilitation.

Objective To systematically evaluate qualitative studies on the experience of transition from adolescent to adult medical care for patients with congenital heart disease(CHD),and to provide a reference for exploring CHD transition management options and developing intervention strategies.Methods A computerized search of PubMed,Embase,Web of Science,Cochrane Library,EBSCO,CINAHL,China Knowledge Network,Wanfang database,Vipshop database,and China Biomedical Literature Database for qualitative studies on the transition experience of CHD patients from adolescence to adult medical care was conducted for the period from the establishment of the database to April 2023.The quality of the literature was evaluated using the Joanna Briggs Institute(JBI)Australian Centre for Evidence-Based Health Care Quality Assessment Criteria for Qualitative Research(2016),and the results were integrated using meta-integration methods.Results A total of 9 studies were included,and 49 research results were extracted,and 11 categories were summarized.The final synthesis included 4 integrated results:①Complex attitudes towards healthcare transition,with both attachment and expectation:attachment to paediatric healthcare providers,expectation of transition to adult healthcare providers.(2)Facing multiple healthcare transition challenges:lack of adequate preparation for healthcare transition,parents withdrawing from the role of disease manager,large differences in services between paediatric and adult healthcare providers.③Expect to receive multiple supports:expect to receive comprehensive health education from healthcare personnel,expect healthcare institutions to set up healthcare transition counselling clinics and achieve handover of illness,expect to receive companionship and support from parents,expect to receive understanding and help from peers.④ Per-ceived benefits of medical transition:increased ability to manage illness,role change and personal growth.Conclusion Adolescents with CHD have a complex experience of transitioning to adult healthcare,and healthcare professionals should be attentive to their feelings,encourage them to deal with challenges positively,and provide adequate information and joint parental and peer support to facilitate a smooth transition to adult healthcare for adolescents.
