With the accelerating trend of population aging, the number of elderly patients with lung cancer continues to rise, and the disease burden is becoming increasingly heavy. The clinical management of these patients faces severe challenges due to their decreased physiological reserve, complex comorbidities, and significant individual heterogeneity. Consequently, under traditional diagnosis and treatment models, doctors often struggle to identify the individualized risks of elderly patients in a timely and comprehensive manner, which can easily lead to decision biases such as undertreatment or overtreatment. In view of this, this study advocates for the establishment of an umbrella decision-making model specifically tailored for elderly lung cancer patients. Grounded in a multidisciplinary team (MDT) platform, this model deeply integrates oncological indicators with the comprehensive geriatric assessment (CGA) system. By holistically considering multidimensional variables including tumor burden, organ function, frailty index, cognitive status, and social support, the model establishes an operational mechanism characterized by "single entry, precise stratification, and targeted selection". Accordingly, patients can be scientifically triaged into distinct intervention tiers, such as active surveillance, minimally invasive surgery, drug therapy, radiotherapy, and best supportive care, thereby achieving real-time alignment between treatment intensity and patient fitness. This article elaborates on the construction logic and key operational procedures of this novel decision-making framework, aiming to guide clinical practice beyond the limitations of a tumor-centric perspective toward a holistic, dynamic, whole-course management strategy. This transition seeks to ensure optimal quality of life and clinical net benefit for elderly patients alongside survival prolongation.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

As global greenhouse gases continue rising, the urgency of more ambitious action is clearer than ever before. China is the world's biggest emitter of greenhouse gases and one of the countries affected most by climate change. The evidence about the impacts of climate change on the environment and human health may encourage China to take more decisive action to mitigate greenhouse gas emissions and adapt to climate impacts. This article aimed to review the evidence of environmental damages and health risks posed by climate change and to provide a new science-based perspective for the delivery of sustainable development goals. Over recent decades, China has experienced a strong warming pattern with a growing frequency of extreme weather events, and the impacts of climate change on China's environment and human health have been consistently observed, with increasing O ₃ air pollution, decreases in water resources and availability, land degradation, and increased risks for both communicable and non-communicable diseases. Therefore, China's climate policy should target the key factors driving climate change and scale up strategic measures to curb carbon emissions and adapt to inevitable increasing climate impacts. It provides new insights for not only China but also other countries, particularly developing and emerging economies, to ensure climate and environmental sustainability whilst pursuing economic growth.

Background and purpose:As one of the first-line treatment methods for differentiated thyroid cancer(DTC),131I treatment is an important therapeutic approach for most patients with medium-high recurrence risk DTC after total or near-total thyroidectomy.Risk stratification and real-time dynamic assessment before 131I treatment after surgery are important steps in deciding on 131I treatment,enabling individualized treatment.This retrospective study aimed to explore the role of diagnostic whole body scan(DxWBS)in the decision-making of treatment for DTC after surgery and before 131I therapy.Methods:DTC patients who underwent pre-ablation evaluation were included.Patients were divided into low,medium and high sTg groups based on their pre-131I treatment stimulated thyroglobulin(sTg)levels(＜1 ng/mL,1 ng/mL≤sTg＜10 ng/mL,sTg≥10 ng/mL).The concordance rates of DxWBS and post treatment whole body scan(RxWBS)in each patient of the whole cohort were compared.The lesion detection rate between DxWBS and RxWBS in different sTg level groups was also explored.The"thyroid stunning effect"by DxWBS was evaluated by RxWBS.Through these analyses,the role of DxWBS in 131I treatment decision-making and its predicting treatment objectives were assessed.This study was approved by the Ethics Committee of Peking Union Medical College Hospital,Peking Union Medical College,Chinese Academy of Medical Sciences(ethics number:JS-2151).Results:A total of 91 patients were included.The low,medium and high sTg groups accounted for 15.4%(14/91),34.1%(31/91)and 50.5%(46/91)of the patients,respectively.Comparison of DxWBS and RxWBS results in the same patients in each sTg group showed no evidence of a stunning effect on 131I treatment.The overall concordance rate between DxWBS and RxWBS was 89.0%(81/91);In different sTg level groups was 100.0%(14/14),90.3%(28/31),84.8%(39/46)respectively.Taking sTg levels into consideration,DxWBS accurately predicted the need for total thyroidectomy,with a 100%(20/20)agreement with RxWBS.Among the 71 patients who received adjuvant therapy and/or remnant ablation due to suspected elevated Tg or high recurrence risk stratification or the iodine-avid metastatic lesions identified by DxWBS,87.5%(63/71)showed only residual thyroid tissue by DxWBS;Through the purpose verification by RxWBS and single photon emission computed tomography(SPECT)/CT,only 12.7%(9/71)of cases were verified as adjuvant or tumoricidal treatment due to iodine-avid cervical lymph node and/or lung metastasis identified by RxWBS,87.3%(62/71)were residual thyroid ablation.In the medium and high sTg group,the overall detection rate of functional cervical lymph node metastasis by DxWBS and RxWBS was 5.5%(5/91).For the detection of functional lung metastases,the overall detection rate of DxWBS was slightly lower than that of RxWBS(3.3%vs 5.5%).This indicates that DxWBS can be used to accurately pre-judge the purposes of 131I treatment,particularly for thyroid ablation and adjuvant therapy.Conclusion:DxWBS did not induce"thyroid stunning"effect.Integrating DxWBS as a theranostic tool into the real-time decision-making and evaluation system of 131I treatment,as well as with sTg and other biochemical indicators,may help to bridge the limitations of static evaluations based on pathology and clinical data,and provides a clear understanding and more precise objectives of 131I treatment.

Objective To investigate programmed death including necroptosis,apoptosis,autophagy,ferroptosis,and pyroptosis in bone marrow megakaryocytes of mice during sepsis and its impact on platelet production capacity and coagulation function in mice.Methods C57BL/6J mice were randomly divided into a sham operation group(sham group)and a sepsis model group(CLP group).Peripheral blood platelets and coagulation function were measured by abdominal aortic blood sampling at 24 h postoperatively in both sham and CLP groups.After the mice were sacrificed,long bones of both lower limbs were taken,and bone marrow megakaryocytes were extracted using megakaryocyte separation solution and immunomagnetic bead separation.Laser confocal microscopy was used to observe the activation of programmed death-related marker molecules in mouse bone marrow megakaryocytes.Flow cytometry was used to detect programmed death rate,platelet production phenotype,and platelet surface markers(CD41,CD42b,CD61)of megakaryocytes.Western blotting was used to detect the expression of programmed death-related proteins in megakaryocytes.Results Compared with the sham group,the CLP group showed significant decreases in the number of platelets during acute sepsis(24 h)(P<0.000 1),significant increases in platelet distri-bution width(PDW)and mean platelet volume(MPV)(P<0.01),significant prolonging of thrombin time(TT),prothrombin time(PT),and activated partial thromboplastin time(APTT)(P<0.000 1,P<0.001,P<0.01),and significant reduction in fibrinogen(Fib)(P<0.000 1).Compared with the Con/sham group,the LPS/CLP group exhibited significant increases in the platelet production phenotype of megakaryocyte,the number of PLP in the supernatant,and the expression levels of platelet surface markers(CD41,CD42b,CD61).The rates of megakaryocyte necroptosis/apoptosis,pyroptosis,and ferroptosis were significantly elevated at 24 h post-CLP surgery.Laser confo-cal microscopy showed significant activation of LC3,P-MLKL,Caspase-1,and Fe2+in megakaryocytes of mice after CLP surgery.Western blotting results revealed that the CLP group exhibited a significant increase in the activa-tion rate of necroptosis-related protein P-MLKL(P<0.001),a significant increase in the cleavage of pyroptosis-related proteins GSDMD and GSDMD-N(P<0.01,P<0.001,respectively),a significant increase in the expres-sion of ferroptosis-related protein ACSL4(P<0.01),and a significant decrease in the expression of GPX4(P<0.01)compared to the sham group.Additionally,the CLP group demonstrated significant increases in the expression of apoptosis-related protein Bax,the cleavage of autophagy-related protein LC3B-Ⅱ,and the expression of P62(P<0.05,P<0.001,P<0.001,respectively).Inhibition of apoptosis with programmed cell death inhibitors decreased platelet production function of megakaryocyte,while inhibition of necroptosis and pyroptosis had limited effects on platelet production function of megakaryocyte.Inhibition of ferroptosis and autophagy enhanced platelet production function of megakaryocyte.Conclusion Significant programmed death of megakaryocytes was observed during the acute phase of sepsis(24 h).Among those megakaryocytes,apoptosis is an important mechanism for the differentia-tion of platelet production phenotype and increased platelet production capacity of megakaryocyte.Overactive autophagy and ferroptosis in megakaryocytes lead to megakaryocyte dysfunction,which is an important mechanism for coagulation abnormalities in sepsis.

Objective:To explore the relationships among psychological resilience,spiritual health,and illness uncertainty in cancer patients,and to analyze the mediating role of disease uncertainty.Methods:The cancer patients were selected by convenience sampling method from Feb 2024 to May 2024 in the Department of Oncology of a Grade Ⅲ-A general hospital in Wuhu City.Data were collected using a general information questionnaire,the Mishel Uncertainty in Illness Scale(MUIS),the Functional Assessment of Chronic Illness Therapy-Spiritual Well-being Scale(FACIT-SP-12,Chinese version),and the Connor-Davidson Resilience Scale(CD-RISC-10).Pearson correlation analysis was conducted to assess the relationships among psychological resilience,illness uncertainty,and spiritual health.The mediating effect of illness uncertainty was tested using Hayes'PROCESS Model 4 and the Bootstrap method.Results:The total scores of spiritual health,psychological resilience and illness uncertainty of cancer patients was(25.11±7.19),(24.36±6.75)and(67.75±13.06),respectively.The spiritual health was positively correlated with psychological resilience(r=0.415,P＜0.01)and negatively correlated with illness uncertainty(r=-0.398,P＜0.01).The psychological resilience was negatively correlated with illness uncertainty(r=-0.668,P＜0.01).Illness uncertainty partially mediated the relationship between psychological resilience and spiritual health,accounting for 35.29%of the total effect.Conclusions:The spiritual health of cancer patients is at a moderate level.Enhancing psychological resilience and reducing illness uncertainty can alleviate psychological burden and improve spiritual health,thereby promoting overall quality of life.
