Refeeding syndrome(RFS)has a high incidence among critically ill patients and significantly impacts the re-covery and prognosis of the patients.In this paper,we reviewed the literature on the risk factors and risk prediction models for RFS,finding the risk factors of RFS included patient-related,treatment-related factors and disease-related factors and the risk prediction models encompassed risk stratification model,risk score models and the Logistic regression models.It was concluded from the review that early assessment was crucial to preventing the occurrence of RFS.However,there was still a lack of reliable RFS risk prediction models with good predictive performance.It was found as well that it was crucial for the prevention of RFS to attach importance to nutritional and serological indicators and other factors.It was expected to be a necessity to conduct prospec-tive and multicenter studies to develop a risk prediction model for predicting RFS for ICU patients.Our review provides a refer-ence for early assessment and intervention for critically ill patients with RFS.

Objective To clarify and analyze the concept and connotation of the reflective practice in nurses.Methods CNKI,Wanfang,CBM,PubMed,Embase,Scopus,CIHNAL database were searched in relation to reflective practice in nurses.The retrieval period was from the inception to Dec.2022.Walker and Avant's concept analysis method was used to analyze the connotation.Results A total of 43 articles were retrieved.6 attributes of reflective practice in nurses were identified,including active engagement,critical thinking,openness and acceptance,making connections with previous knowledge or experiences,extemal support,dynamic and continuity.Antecedents included internal and extemal drivers.The reflective practice in nurses ultimately had a vital impact on themselves,patients and organizations.In recent years Reflective Practice Questionnaire has been one of the most commonly used data collection tools to measure the reflective practice in nurses.Conclusion The concept attributes of reflective practice in nurses were identified by concept analysis method,which provides references for nursing educators to cultivate reflective practice ability of nurses.In future research,researchers can combine the connotations of reflective practice for nurses to develop specific assessment tools for testing the level of reflective practice of nurses and construct the local reflective practice intervention scheme for nurses,so as to promote the development of reflective practice in nursing field in China.

Objective In the context of expanding in size and improving the quality of medical consumables,the"one product,one policy"approach has brought challenges to the management of consumables in public hospitals.This study investi-gated the potential management problems in the process of centralized procurement with volume of medical consumables in a pub-lic tertiary hospital in Guangdong Province,and accordingly worked out the corresponding management countermeasures and then assessed their implementation effects.Methods The fishbone diagrams was applied to systematically analyze the potential prob-lems in the implementation process of centralized procurement with volume of medical consumables.Targeted measures were worked out from May to July 2023 in the hospital.The time series data of centralized procurement of coronary stents,pacemak-ers,tubular/end-to-end anastomoses,and spinal products from December 2022 to December 2023 were analyzed.Changes in the monthly implementation rate and contract completion volume pre-and post-intervention were measured to evaluate the effectiveness of the intervention.Results The fishbone diagrams analysis revealed that the primary factors impeding procurement implementa-tion were internal system flaws,personnel management inadequacy,supply issues,and an absence of an information system.Post-intervention,the monthly implementation rate(t=-4.19,P＜0.05)and contract completion(t=-2.38,P＜0.05)significantly improved.Conclusion The implementation of intervention management for centralized procurement with volume of medical consumables can effectively promote the related implementation effect in the department.In the context of centralized pro-curement,clinical and health management personnel need to bolster their professionalism to ensure the procurement management efficiency and quality.It is crucial to deepen policy understanding and implementation,enhance production and distribution process supervision and disciplinary mechanisms,ensure multi-departmental coordination for supply security,and improve hospi-tal information systems and procurement platforms.

Effective cost control and structure optimization of medical consumables in public hospitals can facilitate a shift from extensive cost control to scientific and refine management.On the premise of ensuring medical quality,reducing the burden of patients'diagnosis and treatment and meeting the actual needs of hospital management,this approach aims to realize valuable healthcare outcomes.This study was conducted in a tertiary hospital,which balanced both the medical and economic val-ue of medical consumables.Using an integrated approach to specialty capacity building and disease structure optimization,the hospital restructured the use of medical consumables in Transcatheter Arterial Embolization(TAE)procedures.It developed standardized pathways and usage protocols tailored to specific diseases and surgical requirements.A targeted consumable usage policy framework was introduced,comprising"one department,one policy;one surgery type,one policy;and one consumable,one policy."This included initiatives such as validating the use of drug-loaded embolic microspheres,conducting multi-depart-mental review meetings,strictly regulating indications for these microspheres,limiting personnel involvement,and negotiating re-duced pricing on imported microspheres.Following implementation,the average case-mix index(CMI)for discharged patients undergoing TAE increased from 2.23 to 2.34(P＜0.001),while the average per-case cost of consumables decreased from 19 600 to 15 600(P＜0.001).These measures offer valuable decision-making and operational reference for hospitals nation-wide,supporting efficient,quality-focused consumables management.

In total, 33 pieces of best evidence were obtained from 8 dimensions, including intracranial pressure related threshold, assessment and monitoring, respiratory care, circulation care, analgesic and sedative care, temperature care, nutrition care and cerebrospinal fluid care.Conclusions:This study summarizes the evidence-based basis of intracranial hypertension nursing in adult patients with severe brain injury, which provides a basis for the standardized construction of clinical nursing strategies and empirical research.

OBJECTIVE: To report on a case of Smith-Magenis syndrome (SMS) due to a rare small-scale deletion. METHODS: Muscle samples from the the third fetus was collected after the in Medical history and clinical data of the patient were collected. The child and his parents were subjected to chromosome karyotyping analysis, multiplex ligation-dependent probe amplification (MLPA) and copy number variation sequencing (CNV-seq). RESULTS: The child was found to have a normal karyotype. MLPA and CNV-seq detection showed that he has harbored a 1.22 Mb deletion and a 0.3 Mb duplication in the 17p11.2 region. Neither of his parents was found to have similar deletion or duplication. CONCLUSION The child was diagnosed with SMS due to a rare 1.22 Mb deletion in the 17p11.2 region, which is among the smallest deletions associated with this syndrome.

Objective:To study the expression of phosphates signal transducer and activator of transcription 3 (pSTAT3) and programmed death ligand-1 (PD-L1) in extranodal NK/T cell lymphomas (ENKTCL) and the relationships of pSTAT3 and PD-L1 expression with the clinicopathological characteristics and prognosis of ENKTCL.Methods:Fifty-one cases of ENKTCL diagnosed at Guangdong Provincial People′s Hospital from June 2015 to February 2019 were included in the study. The expression of pSTAT3 and PD-L1 was examined using immunohistochemistry.Results:There were 35 males and 16 females, ranging from 18 to 85 years old with a median age of 47 years. The positive rates of pSTAT3 and PD-L1 expression were 68.6% (35/51) and 76.5% (39/51), respectively. pSTAT3 expression was correlated with PD-L1 expression ( P=0.033, R=0.322), while there were no associations of pSTAT3 and PD-L1 expression with the clinicopathological characteristics of ENKTCL, including age, sex, clinical site, B symptom, Ann Arbor stage, LDH value, EBV DNA load of peripheral blood and international proliferation index score. Kaplan-Meier survival analysis showed the prognoses of the pSTAT3 and PD-L1 positive groups were slightly better than the respective negative groups, but the differences were not significantly ( P>0.05). Conclusions:pSTAT3 is highly expressed in extranodal NK/T cell lymphoma and related to the expression of PD-L1, which provides a potential target and rationale for combinations of targeted therapies and immune checkpoint blockade inhibitors in the treatment of ENKTCL.

Objective:To investigate the clinicopathological features, treatment and prognosis of fibrin-associated diffuse large B cell lymphoma (DLBCL) arising within concurrent atrial myxoma.Methods:Six cases of fibrin-associated DLBCL arising within concurrent atrial myxoma diagnosed at the Department of Pathology, Guangdong General Hospital, from 2006 to 2019 were included. The histology, immunophenotype, treatment and prognoses were analyzed.Results:The patients′ age ranged from 46 to 78 years (mean 59 years). There were 3 males and 3 females. The tumors were all discovered incidentally on histological examination of surgical pathology specimens excised for atrial myxoma. All patients appeared to have morphological features of DLBCL, B lineage immunophenotype, high proliferative index and latency type III of Epstein-Barr viral infection. They had complete tumor resections without adjuvant chemotherapy and were healthy at 5- to 120-month follow-ups.Conclusions:Fibrin-associated DLBCL arising within concurrent atrial myxoma is an unusual form of DLBCL associated with chronic inflammation, and its clinical outcome is indolent. The findings suggest that this type of lymphoma does not warrant excessive or unnecessary treatments after complete resection.
