Objective:To systematically evaluate studies validating the performance of the Global Leadership Initiative on Malnutrition (GLIM) in diagnosing malnutrition.Methods:Seven Chinese and English databases including Embase, Web of Science (WOS), PubMed, CINAHL, Cochrane Library, SinoMed, CNKI, Wanfang Data, and VIP Database were searched for articles on the validation of GLIM criteria published between September 2018 and September 2024. Two researchers independently performed literature screening and data extraction. The concurrent and predictive validity of the criteria was analyzed.Results:A total of 136 papers were included for analysis. The GLIM criteria for diagnosing malnutrition had a sensitivity of 77%, a specificity of 87%, and an area under the curve (AUC) of 0.90. Malnutrition diagnosed by the GLIM criteria predicted prolonged hospital and intensive care unit (ICU) stays, increased readmission and complication rates (both overall and infectious), reduced survivals (median, overall, and disease-free), and increased in-hospital and follow-up mortalities. Both moderate and severe malnutrition predicted decreased overall survival. However, only three studies analyzed the impact of nutritional therapy on the clinical outcomes of malnourished patients.Conclusions:The GLIM criteria accurately differentiate malnutrition and are a valid predictive tool of clinical outcomes. However, the validity criteria in these validation studies were questionable, along with high methodological heterogeneity. Furthermore, there is a lack of studies validating the role of nutritional therapy in improving the clinical outcomes of malnourished patients.

Pain modulation encompasses a complex neurobiological process, in which the lateral habenula (LHb) plays a crucial role in integrating, regulating and modulating pain signals. It is also involved in pain-related memory functions associated with perception, transmission and regulation of pain. Furthermore, the LHb collaborates with structures such as the spinal dorsal horn, forebrain, and amygdala to form an essential neural circuit that contributes to sensitization, development of tolerance, and adaptation processes related to pain. However, there remains limited understanding regarding the specific roles and interactions among different neuron subtypes within the LHb concerning pain regulation. Additionally, further investigation is warranted to explore functional changes and plasticity within both the LHb and its associated neural circuits in chronic pain models. Future research endeavors should utilize advanced neuroimaging techniques alongside optogenetics and gene editing technologies to elucidate intricate neural circuits, cellular architecture, and molecular mechanisms governing LHb function in pain regulation. In conclusion, this paper aims to comprehensively review existing literature on the involvement of the LHb and its neural circuits in modulating pain, thereby enhancing our understanding of their neurobiological mechanisms while providing novel targets for precise therapeutic strategies aimed at alleviating pain.

【Objective】 To explore the effect of intraoperative cell salvage on allogeneic blood transfusion requirements, coagulation function and electrolytes in postpartum hemorrhage patients. 【Methods】 A study on postpartum hemorrhage patients undergoing cesarean section in the Third Affiliated Hospital of Guangxi Medical University form September 2016 to May 2022 was conducted retrospectively. A total of 137 patients were enrolled and divided into experimental group (n=70) and control group (n=67) according to whether intraoperative cell salvage was used during operation. The blood loss, proportion and volume of allogeneic red blood cells (RBCs) and coagulation component transfusion, hemoglobin (Hb) level, coagulation function, electrolyte, the incidence of complications, proportion of ICU admission, ICU stay and in-hospital stay were compared between the two groups. 【Results】 The proportion of patients receiving allogeneic RBCs in the experimental group and in the control group was 31.4% vs 100.0% (P<0.05). The experimental group also had lower use of plasma (31.4% vs 53.7%, P<0.05). The postoperative 24 h of activated partial thromboplastin time (APTT) and prothrombin time (PT) in the two groups was longer than preoperative, and APTT in the control group did not recover at discharge (P<0.05). Fibrinogen (Fib) decreased postoperative 24 h in the two groups (P<0.05). The blood calcium in the two groups decreased 30 minutes after operation, but the decrease in the experimental group was slight, and two groups did not recover 24 h after operation (P<0.05). There was no statically significant difference in blood loss, volume of allogeneic RBCs and coagulation component transfusion, Hb level, incidence of complications, the proportion of ICU admission, ICU stay and in-hospital stay (P>0.05). 【Conclusion】 This study demonstrated that intraoperative cell salvage could reduce the requirement for allogeneic RBCs without compromising coagulation function in postpartum hemorrhage patients undergoing cesarean section, but the changes of calcium need to be concerned after transfusion.
