To guide transfusion practice in critically ill children who often need plasma and platelet transfusions, the Transfusion and Anemia Expertise Initiative-Control/Avoidance of Bleeding (TAXI-CAB) developed Recommendations and Expert Consensus for Plasma and Platelet Transfusion Practice in Critically Ill Children. This guideline addresses 53 recommendations related to plasma and platelet transfusion in critically ill children with 8 kinds of diseases, laboratory testing, selection/treatment of plasma and platelet components, and research priorities. This paper introduces the specific methods and results of the recommendation formation of the guideline.

BackgroundAs a high prevalence disorder， schizophrenia has caused significant burden to family and society due to the impairment of occupational and social function. Currently， the dominant vocational training model in China follows a paternalistic， clinician-led decision-making approach. Although it improves patients' social function to some extent， it undermines their autonomy and treatment adherence. Therefore， it is urgently necessary to explore a new intervention method to enhance treatment compliance and social function in patients. ObjectiveTo explore the impact of shared decision-making oriented vocational training on social function in hospitalized schizophrenia patients， so as to provide references for rehabilitation interventions. MethodsA total of 68 patients diagnosed with schizophrenia according to the International Classification of Diseases， tenth edition （ICD-10） criteria were consecutively enrolled from January to June 2024 at The Third People's Hospital of Wenjiang Distric， Chengdu. Participants were randomly allocated into the research group （n=34） and the control group （n=34） using a random number table method. Both groups received routine rehabilitation training， while the research group received shared decision-making oriented vocational training for 12 weeks， 2 times a week for 2 hours each time. Before and at the 4^th and 12^th week of intervention， two groups were evaluated by General Self-Efficacy Scale （GSES）， Stigma Scale for Mental Illness （SSMI）， Scale of Social function of Psychosis Inpatients （SSFPI） and Inpatient Psychiatric Rehabilitation Outcome Scale （IPROS）. ResultsA total of 63 participants completed the study， with 30 cases in the research group and 33 cases in the control group. Repeated measures ANOVA revealed statistically significant time effects and interaction effects in both groups for GSES， SSMI， SSFPI and IPROS scores （F=20.451， 16.022； 26.193， 12.944； 23.957， 5.023； 11.776， 3.985， P<0.05 or 0.01）， while no significant group effects were observed （F=0.188， 0.742， 1.878， 0.474， P>0.05）. At the 12^th week of intervention， there were statistically significant differences in GSES， SSMI， SSFPI and IPROS scores between the two groups. ConclusionShared decision-making oriented vocational training may help to improve social function in patients with schizophrenia. ［Funded by 2023 Chengdu Medical Research Project （number， 2023468）］

ObjectiveTo explore the construction of a risk assessment indicator system for common infectious diseases in Shanghai’s childcare institutions, and to provide a reference standard for the prevention and control of infectious diseases, staff training and system construction in childcare institutions. MethodsBy combining the Delphi method with the literature review and expert consultation, the hierarchical dimensions and items at all levels of the risk assessment indicator system for common infectious diseases in Shanghai’s childcare institutions were constructed, and the weighting coefficients were determined by analytic hierarchy process. ResultsA total of 14 experts from the field of childcare institutions, infectious disease control, child healthcare and health supervision participated in the Delphi consultation. The system consisted of four core dimensions: organizational management, team building, hardware equipment, and infectious disease surveillance and disposal, with the weighting coefficients of 0.285 9, 0.261 6, 0.204 3 and 0.248 2, respectively. The evaluation indicator system consisted of 4 primary indicators, 15 secondary indicators and 45 tertiary items. The positivity coefficients of the two rounds of Delphi consultation were 0.93 and 1.00, the authority coefficients were both 0.81, and the Kendall’s coefficient of concordance were 0.44 and 0.49, respectively (P<0.01). ConclusionThe high expert engagement and coordination indicate that organizational management and team building remain the critical priorities for infectious disease prevention and control in Shanghai’s childcare institutions. It is recommended to strengthen financial investment, improve institutional mechanisms, and enhance personnel reserves and capacity building for healthcare teachers, thereby systematically upgrading the infectious disease control capabilities of childcare institutions.

Based on systematic review and consensus meetings of international multidisciplinary experts, the Transfusion and Anemia Expert Initiative—Control/Avoidance of Bleeding (TAXI-CAB) project team developed management strategies for platelet and plasma transfusion in critically ill children. This consensus presents five expert consensus statements and two recommendations addressing two key questions: 1) What Laboratory Tests and Physiologic Triggers Should Guide the Decision to Administer a Platelet or Plasma Transfusion in Critically ill Children? 2) What Product Attributes Are Optimal to Guide Specific Product Selection? This consensus provides guidance for decision-making regarding plasma and platelet transfusion in critically ill children in two aspects: relevant laboratory testing indicators and additional special properties of blood components. This article explains the rationale behind the recommendations in this part of the guideline, aiming to emphasize the need for clinicians to develop transfusion strategies based on multidimensional assessment, while calling for enhanced interdisciplinary collaboration and evidence-based research to optimize blood management in critically ill children, reducing the risk of over-transfusion and improving treatment outcomes. Furthermore, there remains an urgent need for further research to explore laboratory indicators associated with bleeding risk to guide transfusion therapy.

Objective: Recent studies indicate that 3 morphological types of atlanto-occipital joint (AOJ) exist in the craniovertebral junction and are associated with type II basilar invagination (BI) and atlanto-occipital instability. However, the actual biomechanical effects remain unclear. This study aims to investigate biomechanical differences among AOJ types I, II, and III, and provide further evidence of atlanto-occipital instability in type II BI. Methods: Models of bilateral AOJ containing various AOJ types were created, including I-I, I-II, II-II, II-III, and III-III models, with increasing AOJ dysplasia across models. Then, 1.5 Nm torque simulated cervical motions. The range of motion (ROM), ligament and joint stress, and basion-dental interval (BDI) were analyzed. Results: The C0–1 ROM and accompanying rotational ROM increased progressively from model I-I to model III-III, with the ROM of model III-III showing increases between 27.3% and 123.8% indicating ultra-mobility and instability. In contrast, the C1–2 ROM changes were minimal. Meanwhile, the stress distribution pattern was disrupted; in particular, the C1 superior facet stress was concentrated centrally and decreased substantially across the models. The stress on the C0–1 capsule ligament decreased during cervical flexion and increased during bending and rotating loading. In addition, BDI gradually decreased across the models. Further analysis revealed that the dens showed an increase of 110.1% superiorly and 11.4% posteriorly, indicating an increased risk of spinal cord impingement. Conclusion Progressive AOJ incongruity critically disrupts supportive tissue loading, enabling incremental atlanto-occipital instability. AOJ dysplasia plays a key biomechanical role in the pathogenesis of type II BI.

The application of digital technology in teaching and clinical practice has been hindered by the lack of integrity,consis-tency and accuracy in current digital models.Despite the efforts of domestic and international scholars,the localization,refining and standardization of model data for digital dental models remain inadequate,which limits the promotion and application of digital dental models.A preliminergly produced precise,standardized and multi-form applicable 3D dental-cranio-cervical digital model based on Chinese anatomical data is reported in this paper.The further improvement,application and promotion of this model are expected to contribute to the improvement of the quality of dental education and clinical efficiency.

Objective:To analyze the therapeutic effect and safety of simultaneous integrated boost intensity-modulated radiotherapy for lung cancer brain metastases.Methods:A total of 300 patients with lung cancer brain metastases admitted to the Department of Oncology, Qingdao Municipal Hospital from March 2021 to March 2023 were selected as the study objects. The patients were divided into control group ( n=150) and study group ( n=150) by random number table method. The control group received sequential three-dimensional conformal radiotherapy, while the study group received simultaneous integrated boost intensity-modulated radiotherapy. The short-term and medium-term efficacy, target dose, and adverse reactions were compared between the two groups. Results:The short-term and medium-term total effective rates of the study group were 73.33% (110/150) and 88.67% (133/150), respectively, which were higher than those of the control group [51.33% (77/150) and 71.33% (107/150) ] ( χ2=15.46, P<0.001; χ2=14.08, P<0.001). The D min in gross tumor planning target volume and whole brain clinical planning target volume of the study group were (23.78±1.11) and (58.46±0.55) Gy, respectively, which were higher than those in the control group [ (16.67±1.08) and (53.44±0.74) Gy], with statistically significant differences ( t=56.22, P<0.001; t=66.68, P<0.001). The D mean in gross tumor planning target volume and whole brain clinical planning target volume of the study group were (44.12±0.87) and (62.19±0.57) Gy, respectively, which were higher than those in the control group [ (37.55±0.89) and (57.78±0.82) Gy], with statistically significant differences ( t=64.65, P<0.001; t=54.08, P<0.001). The total incidence of adverse reactions was 30.67% (46/150) in the study group and 36.67% (55/150) in the control group, with no significantly significant difference ( χ2=1.20, P=0.271) . Conclusion:Compared with sequential three-dimensional conformal radiotherapy, simultaneous integrated boost intensity-modulated radiotherapy has better short-term and medium-term efficacy in patients with lung cancer brain metastases. Target dose can be increased without increasing adverse reactions.

Background Organic phosphate flame retardants are emerging environmental pollutants. While there have been multiple toxicities reported following organic phosphate flame retardants exposure, few studies focus on their potential developmental toxicities. It is necessary to elucidate these developmental toxicological effects and underlying mechanisms to improve risk assessments and better protect sensitive populations. Objective To evaluate potential developmental toxicities in early chicken embryos following exposure to triphenyl phosphate (TPhP) or cresyl diphenyl phosphate (CDP), to reveal TPhP and CDP’s capabilities to activate peroxisome proliferator-activated receptor γ (PPARγ) in vivo in an established chicken embryo gene reporter system, and to investigate the roles of PPARγ in TPhP/CDP-induced developmental toxicities with lentivirus-mediated in vivo gene silencing. Methods Firstly, diverse doses of TPhP and CDP were injected into the air sacs of fertilized eggs to assess the development of chicken embryos after 6 d of incubation, and an optimal dose was chosen for subsequent experiments. Subsequently, the report gene system was employed to evaluate the intraembryonic activation of PPARγ by TPhP and CDP. Eventually, PPARγ was silenced using lentivirus, and the embryos were co-treated with TPhP and CDP to further disclose the roles of PPARγ in the observed developmental toxicity. Results Following developmental exposure to TPhP or CDP, significantly lower chicken embryo weights (normalized with egg weights) were observed in the 6 d embryos (10, 30 mg·kg⁻¹ TPhP and 3, 10, 30 mg·kg⁻¹ CDP), indicating that both chemicals have general developmental toxicities and CDP is more potent. Additionally, exposure to CDP also resulted in remarkably increased sagittal brain area (normalized to embryo weights) and decreased sagittal eye area (normalized to embryo weights) (P<0.05), suggesting that CDP has specific developmental neurotoxicity and ocular toxicity. The PPARγ reporter gene experiment results revealed that rosiglitazone (positive control), TPhP, and CDP all significantly activated PPARγ relative to control (P<0.05). The potency order was rosiglitazone > CDP > TPhP. The lentivirus microinjection successfully achieved in vivo silencing of PPARγ in developing chicken embryos, and the estimated silencing efficacy was approximately 55% according to the real-time quantitative polymerase chain reaction (qRT-PCR) results. The in vivo silencing of PPARγ effectively alleviated TPhP or CDP-induced decrease of embryo weights (P<0.05), as well as CDP-induced increase of brain areas and decrease of eye areas (P<0.05). Conclusions Both TPhP and CDP can induce general developmental toxicities in early chicken embryos, and CDP is more potent than TPhP. Meanwhile, CDP can induce specific enlarged brain area and decreased eye area. The observed toxicities are associated with in vivo activation of PPARγ.
