Disease Risk Comorbidity Index for Patients Receiving Haploidentical Allogeneic Hematopoietic Transplantation

We aimed to develop a disease risk comorbidity index(DRCI)based on disease risk index(DRI)and Hematopoietic Cell Transplantation-Specific Comorbidity Index(HCT-CI)in patients receiving haploidentical hematopoietic stem cell transplantation(haplo-HSCT).We identified the prognostic factors of disease-free survival(DFS)in a training subset(n=593),then assigned a weighted score using these factors to the remaining patients(validation subset;n=296).The multivariable model identified two independent predictors of DFS:DRI and HCT-CI before transplantation.In this scoring system,we assigned a weighted score of 2 to very high-risk DRI,and assigned a weighted score of 1 to high-risk DRI and intermediate-and high-risk HCT-CI(i.e.,haplo-DRCI).In the validation cohort,the three-year DFS rate was 65.2%(95%confidence interval(CI),58.2%–72.2%),55.8%(95%CI,44.9%–66.7%),and 32.0%(95%CI,5.8%–58.2%)for the low-,intermediate-,and high-risk group,respectively(P=0.005).Haplo-DRCI can also predict DFS in disease-specific subgroups,particularly in acute leukemia patients.Increasing score was also significantly predictive of increased relapse,increased non-relapse mortality(NRM),decreased DFS,and decreased overall survival(OS)in an independent historical cohort(n=526).These data confirmed that haplo-DRCI could effectively risk stratify haplo-HSCT recipients and provide a tool to better predict who will best benefit from haplo-HSCT.

Extreme Obesity Treated with Integrated Traditional Chinese and Western Medicine and Construction of an Innovative Obesity Diagnosis and Treatment Model: A Case Report

Background:The incidence of obesity is increasing each year,and is often accompanied by multi-system metabolic disorders,typically chronic diseases and multi-disease superposition disease states.Metabolic surgery is an important treatment option for patients with extreme obesity;however,surgical difficulties and perioperative complications are more serious in these patients.Therefore,there is an urgent need for a new comprehensive diagnosis and treatment model to reduce the weight of patients prior to surgery,subsequently reducing the risks of surgery.Case summary:This model combines traditional Chinese medicine(TCM),external TCM treatment,and health management with western technique of metabolic surgery.Obesity is recognized and treated by multidisciplinary,multi-channel,and multi-means,constituting an innovative diagnosis and treatment model of obesity in integrated traditional Chinese and Western medicine.The application of this model in the treatment of a patient with extreme obesity having multiple systemic diseases is described herein.Conclusion:The integrated traditional Chinese and Western medicine obesity diagnosis and treatment model can be used for precise syndrome differentiation,individualized treatment,and follow-up management of patients with extreme obesity,with strong scalability and significant clinical efficacy.

Graphdiyne(C_(n)H_(2n-2))as an"electron transfer bridge"boosting photocatalytic hydrogen evolution over Zn_(0.5)Co_(0.5)S/MoS_(2)S-scheme heterojunction

In the process of photocatalytic water cracking,the migration rate and utilization rate of photogenerated charges determine the hydrogen evolution performance of the catalyst.In this paper,a carbon isotope superconducting material graphdiyne(GDY)is prepared by mechanical ball milling and introduced into the S-scheme heterojunction Zn_(0.5)Co_(0.5)S/MoS_(2)inorganic system.In terms of hydrogen evolution kinetics,GDY acts as an electron bridge,not only accelerating the migration of photogenerated carriers but also improving the utilization of photogenerated charges.Morphologically,the large twodimensional layer provides more loading and anchoring points for Zn_(0.5)Co_(0.5)S/MoS_(2),which increases the number of active sites.The ternary composite catalyst 20%GDY/Zn_(0.5)Co_(0.5)S/MoS_(2)(20-GCSM)generates 69.94μmol of hydrogen(5 h)in triethanolamine solution.It is 2.97 and1.80 times higher than Zn_(0.5)Co_(0.5)S and Zn_(0.5)Co_(0.5)S/MoS_(2),respectively.After the cyclic experiment,it still has stable hydrogen evolution performance after standing for24 h(under dark conditions).In addition,the potential mechanism of photocatalytic hydrogen evolution is demonstrated through in-situ X-ray photoelectron spectroscopy.This work provides a reference for further research in the field of introducing carbon materials into photocatalytic systems and improving the utilization of photogenerated charges.

Successful hematopoietic stem cell transplantation with haploidentical donors and non-irradiation conditioning in patients with Fanconi anemia

To the Editor:Allogeneic hematopoietic stem cell transplantation(HSCT)is the only curative option for bone marrow(BM)abnormalities in Fanconi anemia(FA).However,patients with FA cannot tolerate the toxicity of the therapeutic regimen for acquired aplastic anemia,which mainly contains 200 mg/kg cyclophosphamide(CTX),and low-dose CTX regimens are considered more suitable.Some centers have also added different doses of irradiation to the conditioning regimen.[1]Due to their side effects on growth and development and the possibility of developing a secondary malignant disease,some trials have replaced the irradiation with fludarabine.Moreover,data on transplants from haploidentical donors are scarce.
