Objective To evaluate the transition rules of normal body mass index(BMI),overweight and metabolic syndrome(MetS)in patients with major depressive disorder(MDD).Methods Patients with MDD who had multiple admission records between Jan 2016 and Nov 2021 in Beijing Anding Hospital,Capital Medical University were included.Based on the overweight and metabolic syndrome status assessed at each admission,the patients were categorized into three states:normal BMI,overweight and metabolic syndrome.A multi-state Markov model was used to analyze the transition intensity and transition frequency between three states and the influence of covariates on transitions.Results A total of 892 records of 398 subjects were included,with a median age of 56 years old and 31.4% males.The median follow-up period was 40 months.The multi-state model showed that there were 494 transitions between the three states,of which 5.1% moved from normal BMI to overweight and 5.5% moved from overweight to MetS.The intensity of transition was the highest from overweight to MetS,9.52 times greater than overweight to normal BMI.After 48.53 months,MDD patients with normal BMI began to transition to MetS.For overweight MDD patients,the transition to MetS started after 8.77 months.MDD patients with normal BMI or overweight had 31.4% and 50.4% probabilities of developing Mets after 36 months.For MDD patients comorbid with MetS,the probability of staying at MetS was 51.2% after 36 months.Multivariate analysis showed that being unmarried was a risk factor against developing overweight in normal BMI MDD patients,while a higher level of education was a protective factor against developing MetS in overweight MDD patients.Conclusion MDD patients exhibited a higher intensity and risk of developing MetS,and it is not easy to reverse MetS,suggesting that BMI management and MetS intervention should be strengthened in MDD patients.

Objective To investigate the longitudinal clinical manifestations of acute radiation dermatitis(ARD)induced by particle therapy in nasopharyngeal carcinoma patients and to analyze associated risk factors.Methods A longitudinal study design was employed,encompassing nasopharyngeal carcinoma patients who underwent particle therapy at the Shanghai Proton and Heavy Ion Center from Mar to Sept 2023.Participants were assessed weekly(1-12 weeks)following the commencement of radiotherapy and at baseline,prior to the start of treatment.Data collection included the patient demographic questionnaire,the Radiation Therapy Oncology Group(RTOG)grading criteria for acute radiation injury,and the radiation-induced skin reaction assessment scale(RISRAS).Photographic documentation was utilized to capture changes in the irradiated skin area.The enrolled patients with nasopharyngeal carcinoma were grouped according to different particle therapy regimens.Survival data were analyzed by Log-rank and Cox regression methods,while a linear mixed-effects model was applied to repeated measures data.Results A total of 119 patients with nasopharyngeal carcinoma were enrolled.The overall incidence of ARD was 89.1%,which included 39.5%of grade 1,45.4%of grade 2 and 4.2%of grade 3.With the extension of time,the severity of ARD peaked at week 7(RISRAS=13.26±4.512),then began to decrease,ultimately reaching a lower level.Multiple Cox proportional hazards models were constructed,revealing that proton/heavy ion radiotherapy was associated with a lower risk of ARD compared to photon/proton plus heavy ion radiotherapy(HR=0.19,95%CI:0.04-0.92,P=0.039).Additionally,concurrent cisplatin/nedaplatin chemotherapy was identified as a risk factor for the development of ARD.Least squares(LS)mean differences were calculated at different time points,and the results demonstrated that the RISRAS scores of the photon/proton plus heavy ion group were consistently and significantly higher from week 5 to week 7 compared with the proton plus heavy ion group,and despite a decrease by week 8,statistical differences remained(week 5:LS mean difference 3.35,95%CI:0.94-5.76,P=0.007;week 6:LS mean difference 5.23,95%CI:2.20-8.26,P=0.001;week 7:LS mean difference 7.13,95%CI:3.67-10.59,P<0.001;week 8:LS mean difference 4.04,95%CI:0.74-7.34,P=0.017).Patients undergoing concurrent cisplatin chemotherapy had higher RISRAS scores from week 7 to week 8 of radiotherapy compared with those not receiving chemotherapy[week 7:adjusted mean difference(Adj.MD)4.20,95%CI:1.96-6.57,P=0.006;week 8:Adj.MD 2.79,95%CI 0.55-5.03,P=0.015].Similarly,patients on concurrent nedaplatin chemotherapy had higher RISRAS scores from weeks 6 to 7 compared with those not on chemotherapy(week 6:Adj.MD 3.75,95%CI:1.54-5.96,P=0.001;week 7:Adj.MD 4.41,95%CI:2.12-6.70,P<0.001).Skin care measures during treatment and accompanying symptoms such as weight loss were not statistically associated with the development of ARD.Conclusion Proton/heavy ion radiotherapy has a lower risk of ARD,while concurrent cisplatin/nedaplatin chemotherapy is a risk factor for ARD.
