Vitamin D(VD)is a fat-soluble vitamin closely related to bone health and calcium and phosphorus metabolism.VD deficiency in humans has become a global public health problem,especially in pregnant women as it affects maternal health and fetal growth,develo-pment,and susceptibility to many diseases.Recent studies have shown that adequate cord blood VD levels are associated with a reduced incidence of eczema in infants aged<1 year.With the increasing annual incidence of eczema in infants,its association with VD nutritional status has begun to receive attention.However,few epidemiological studies have investigated the association between VD levels during pregnancy and infantile eczema,and the results have been inconsistent.Therefore,this study reviews the association between VD nutri-tional status during pregnancy and infantile eczema,which may provide a theoretical basis for further exploring the role of VD nutritional status in the development of infantile eczema and taking targeted preventive and curative measures.

OBJECTIVE:To systematically evaluate the efficacy of transcranial direct current stimulation on the motor function of patients with Parkinson's disease,and to compare the efficacy of transcranial direct current stimulation at different targets on the motor function of patients with Parkinson's disease,so as to provide a theoretical basis for the target selection of transcranial direct current stimulation in clinical practice. METHODS:Cochrane Library,PubMed,Web of Science,CNKI,VIP,WanFang Data were retrieved for randomized controlled trials on the improvement of motor function in patients with Parkinson's disease by transcranial direct current stimulation published from the database inception to January 2023.The keywords were"Parkinson,transcranial direct current stimulation"in English and Chinese.The quality of the included studies was evaluated using the Cochrane 5.1.0 risk of bias assessment tool and the PEDro scale.Meta-analysis of outcome indicators was performed using RevMan 5.4 and Stata 17.0 software. RESULTS:Fifteen randomized controlled trials were finally included,and the PEDro scale showed that all were high-quality or very high-quality studies.Meta-analysis showed that transcranial direct current stimulation significantly improved Unified-Parkinson Disease Rating Scale part III score[mean difference(MD)=-2.49,95%confidence interval(CI):-4.42 to-0.55,P<0.05),step frequency score(MD=0.07,95%CI:0.03-0.11,P<0.05)and step speed score(MD=0.02,95%CI:0.00-0.05,P<0.05),but not for Berg Balance Scale scores(MD=2.57,95%CI:-0.74 to 5.87,P>0.05).Network Meta-analysis probability ranking:In terms of Unified-Parkinson Disease Rating Scale part III scores,the probability ranking results of target stimulation efficacy were dorsal lateral prefrontal cortex(52.4%)>primary motor cortex(45.8%)>central point of the brain(1.8%)>conventional rehabilitation(0%);in terms of gait frequency scores,the probability probability ranking results of target stimulation efficacy were cerebellum(50.1%)>central point of the brain(45.8%)>dorsal lateral prefrontal cortex(3.9%)>primary motor cortex(0.2%)>conventional rehabilitation(0%);in terms of gait speed scores,the probability ranking results of target stimulation efficacy were cerebellum(64.8%)>dorsal lateral prefrontal cortex(23.8%)>central point of the brain(9.4%)>primary motor cortex(1.7%)>conventional rehabilitation(0.4%);in terms of Berg Balance Scale scores,the probability ranking results of target stimulation efficacy were cerebellum(77.4%)>dorsal lateral prefrontal cortex(20.7%)>central point of the brain(0.7%)>conventional rehabilitation(0.2%). CONCLUSION:Transcranial direct current stimulation significantly improves motor function of patients with Parkinson's disease,with better motor coordination in the dorsolateral prefrontal cortex and better walking and balance in the cerebellum.

The correlation between hearing loss (HL) and physical performance in patients receiving maintenance hemodialysis (MHD) remains poorly investigated. This study explored the association between HL and physical performance in patients on MHD. Methods: This multicenter cross-sectional study was conducted between July 2020 and April 2021 in seven hemodialysis centers in Shanghai and Suzhou, China. The hearing assessment was performed using pure-tone average (PTA). Physical performance was assessed using the Timed Up and Go Test (TUGT), handgrip strength, and gait speed. Results: Finally, 838 adult patients (male, 516 [61.6%]; 61.2 ± 2.6 years) were enrolled. Among them, 423 (50.5%) had mild to profound HL (male, 48.6% and female, 53.4%). Patients with HL had poorer physical performance than patients without HL (p < 0.001). TUGT was positively correlated with PTA (r = 0.265, p < 0.001), while handgrip strength and gait speed were negatively correlated with PTA (r = –0.356, p < 0.001 and r = –0.342, p < 0.001, respectively). Physical performance in patients aged <60 years showed significant dose-response relationships with HL. After adjusting for confounders, the odds ratios (95% confidence intervals) for HL across the TUGT quartiles (lowest to highest) were 1.00 (reference), 1.15 (0.73–1.81), 1.69 (1.07–2.70), and 2.87 (1.69–4.88) (p for trend = 0.005). Conclusion: Lower prevalence of HL was associated with a faster TUGT and a stronger handgrip strength in patients on MHD.

Objective:To evaluate the efficacy and safety of mitoxantrone hydrochloride liposome injection in the treatment of peripheral T-cell lymphoma (PTCL) in a real-world setting.Methods:This was a real-world ambispective cohort study (MOMENT study) (Chinese clinical trial registry number: ChiCTR2200062067). Clinical data were collected from 198 patients who received mitoxantrone hydrochloride liposome injection as monotherapy or combination therapy at 37 hospitals from January 2022 to January 2023, including 166 patients in the retrospective cohort and 32 patients in the prospective cohort; 10 patients in the treatment-na?ve group and 188 patients in the relapsed/refractory group. Clinical characteristics, efficacy and adverse events were summarized, and the overall survival (OS) and progression-free survival (PFS) were analyzed.Results:All 198 patients were treated with mitoxantrone hydrochloride liposome injection for a median of 3 cycles (range 1-7 cycles); 28 cases were treated with mitoxantrone hydrochloride liposome injection as monotherapy, and 170 cases were treated with the combination regimen. Among 188 relapsed/refractory patients, 45 cases (23.9%) were in complete remission (CR), 82 cases (43.6%) were in partial remission (PR), and 28 cases (14.9%) were in disease stabilization (SD), and 33 cases (17.6%) were in disease progression (PD), with an objective remission rate (ORR) of 67.6% (127/188). Among 10 treatment-na?ve patients, 4 cases (40.0%) were in CR, 5 cases (50.0%) were in PR, and 1 case (10.0%) was in PD, with an ORR of 90.0% (9/10). The median follow-up time was 2.9 months (95% CI 2.4-3.7 months), and the median PFS and OS of patients in relapsed/refractory and treatment-na?ve groups were not reached. In relapsed/refractory patients, the difference in ORR between patients with different number of treatment lines of mitoxantrone hydrochloride liposome injection [ORR of the second-line, the third-line and ≥the forth-line treatment was 74.4% (67/90), 73.9% (34/46) and 50.0% (26/52)] was statistically significant ( P = 0.008). Of the 198 PTCL patients, 182 cases (91.9%) experienced at least 1 time of treatment-related adverse events, and the incidence rate of ≥grade 3 adverse events was 66.7% (132/198), which was mainly characterized by hematologic adverse events. The ≥ grade 3 hematologic adverse events mainly included decreased lymphocyte count, decreased neutrophil count, decreased white blood cell count, and anemia; non-hematologic adverse events were mostly grade 1-2, mainly including pigmentation disorders and upper respiratory tract infection. Conclusions:The use of mitoxantrone hydrochloride liposome injection-containing regimen in the treatment of PTCL has definite efficacy and is well tolerated, and it is a new therapeutic option for PTCL patients.

BACKGROUND: Reports on the prevalence of psoriatic arthritis (PsA) among Chinese patients with psoriasis are very limited. This study, conducted by rheumatologists, estimated the prevalence of PsA in a large number of Chinese patients with psoriasis. METHODS: Consecutive patients with a confirmed diagnosis of psoriasis attending nine dermatology clinics in five hospitals were recruited. All psoriasis patients were asked to complete a questionnaire comprising 16 questions to identify possible cases of PsA. All patients with one or more positive answers to the questionnaire were evaluated by two experienced rheumatologists. RESULTS: A total of 2434 psoriasis patients, including 1561 males and 873 females, were enrolled. Both the questionnaire and rheumatologists' examinations were completed in the dermatology clinics. The results identified 252 patients with PsA, comprising 168 males and 84 females. The overall prevalence of PsA among psoriasis patients was 10.4% (95% confidence interval [95% CI], 9.1%-11.7%). By sex, the prevalence was 10.8% (95% CI, 9.2%-12.5%) for males and 9.6% (95% CI, 7.7%-11.9%) for females and there was no significant sex difference in the prevalence of PsA (P = 0.38). Of the 252 PsA patients, 125 (49.6%, 95% CI, 41.3%-59.1%) were newly diagnosed by rheumatologists. Consequently, the prevalence of undiagnosed PsA among psoriasis patients was 5.2% (95% CI, 4.4%-6.2%). CONCLUSION The prevalence of PsA in the Chinese population with psoriasis is about 10.4%, which is almost double that of previous reports in the Chinese population, but lower than that in Caucasians.

Objective:The effect of three-dimensional(3D)printed bone-attached guide plate assisted cannulated screw fixation of pelvic fracture is reliable,but extensive soft tissue dissection is still required when installing the guide plate.This study aims to compare the efficacy of posterior pelvic ring fracture fixation with iliosacral screw insertion between the assistance of modified percutaneous patient specific 3D printed guide template and conventional fluoroscopy. Methods:From May,2019 and September 2021,28 patients sustained posterior pelvic ring fractures were randomized into 2 groups:A guide template group,in which the iliosacral screw was inserted for fixation of the posterior pelvic ring fracture with the assistance of modified percutaneous patient specific 3D printed guide template,and a fluoroscopy group,in which the iliosacral screw was inserted under the guidance of conventional fluoroscopy.The operation time,fluoroscopic frequency,intraoperative blood loss,and incision length were recorded for each screw insertion.Fracture reduction was evaluated according to the Matta criteria.The screw position was evaluated according to the modified Gras classification,and the functional outcome was evaluated according to Majeed score.The parameters of both groups were compared,and statistical analysis was performed. Results:All the 28 patients were followed up for 12-24 months.Of them,15 iliosacral screws were inserted in 14 patients in the guide template group,and 14 iliosacral screws were inserted in 14 patients in the fluoroscopy group.The operation time,fluoroscopic frequency,screw deviation,incision length,and blood loss in the guide template group were 20-30(25.8±2.8)min,9-15(12.2±1.9),2-4(2.6±0.7)mm,4-5(4.6±0.5)cm,and 5-10(7.8±1.7)mL,respectively,whereas those in the fluoroscopy group were 30-60(48.1±7.5)min,40-96(64.7±16.3),3-6(4.2±0.9)mm,0.8-1.2(1.0±0.1)cm,and 2-5(3.1±1.3)mL,respectively,and there were statistical significance(all P<0.001).Fracture reduction was evaluated according to the Matta criteria,and all the patients reached excellence and good(P=0.584)in the 2 groups.According to modified Gras classification,there were 12 Grade Ⅰ screws,3 Grade Ⅱ screws,and 0 Grade Ⅲ screws in the guide template group,and 10 Grade Ⅰ screws,3 Grade Ⅱ screws,and 1 Grade Ⅲ screw in the fluoroscopy group,with no statistical significance(P=0.334).The functional outcome was evaluated according to Majeed score at the last follow-up,without significant difference between the guide template group and the fluoroscopy group(P=0.908). Conclusion:Compared with the conventional fluoroscopy,it would cost less operation time,less fluoroscopic frequency and increase more accurate screw insertion to fixate the posterior pelvic ring fracture with the assistance of modified percutaneous patient specific 3D printed guide template.

Background Occupational stress and depressive symptoms of disease prevention and control personnel are serious. Objective To investigate the relationship between occupational stress, psychological capital, and depressive symptoms of disease prevention and control personnel, and analyze the potential mediating effect of psychological capital on the relationship between occupational stress and depressive symptoms. Methods From July to September 2020, a cluster random sampling method was used to select 2201 employees from 21 centers for disease control and prevention as study subjects covering all levels of administrative divisions in Jiangsu Province. A total of 2036 valid questionnaires were collected with a recovery rate of 92.5%. The Core Occupational Stress Scale, Patient Health Questionnaire, and Psychological Capital Questionnaire were used to investigate their occupational stress, depressive symptoms, and psychological capital. Stratified regression analysis was used to explore the effects of occupational stress and psychological capital on depressive symptoms. A mediating effect model was used to analyze and verify the potential mediating effect of psychological capital on the relationship between occupational stress and depressive symptoms. Results The total scores in M (P₂₅, P₇₅) of occupational stress, depressive symptoms, and psychological capital in the target population were 42.0 (37.0, 48.0), 8.0 (4.0, 9.0), and 4.6 (4.0, 5.0) respectively. The positive rate of occupational stress was 31.0% (631/2036), and the positive rate of depressive symptoms was 22.0% (448/2036). The dimensional scores of organization and reward, and demand and effort of occupational stress were positively correlated with the total score of depressive symptoms [Spearman correlation coefficients (r_s) were 0.371 and 0.269, P<0.05]. The dimensional scores of social support and autonomy of occupational stress and the score of psychological capital were negatively correlated with the total score of depressive symptoms (r_s=−0.373, −0.112, −0.494, P<0.05). The organization and reward, and demand and effort had positive effects on depressive symptoms (b=0.188, 0.177, P<0.05), while social support and autonomy had negative effects on depressive symptoms (b=−0.290, −0.078, P<0.05), and associated with a 22.5% increase of explanatory variance. Psychological capital had a negative effect on depressive symptoms (b=−0.368, P<0.05), and associated with an 11.0% increase of explanatory variance. Psychological capital had mediating effects on the associations of social support, organization and reward, and autonomy with depressive symptoms, and the mediating effect values were −0.210 (95%CI: −0.253-−0.171), 0.096 (95%CI: 0.071-0.122), and −0.164 (95%CI: −0.229-−0.103), respectively. The corresponding mediating effect percentages were 40.23%, 26.97%, and 45.56%, respectively. Conclusion Occupational stress of disease prevention and control personnel can directly affect depressive symptoms, but also indirectly through psychological capital. Psychological capital plays a partial mediating role in the associations of social support, organization and reward, and autonomy of occupational stress with depressive symptoms. The occurrence of depressive symptoms can be reduced by decreasing occupational stress and increasing psychological capital.
