BackgroundMigraine is a common chronic neurological disease， and patent foramen ovale （PFO） has been closely associated with migraine. Current research primarily focuses on the pathological mechanism and the therapeutic effects of interventional closure， with limited attention paid to the impact of PFO on sleep quality in migraine patients. ObjectiveTo compare the difference in sleep quality between PFO-positive and PFO-negative migraine patients， and to analyzes influencing factors of sleep quality in PFO-positive migraine patients， so as to provide references for clinical interventions to improve sleep quality in PFO-positive migraine patients. MethodsA total of 673 migraine patients who met the diagnostic criteria of migraine in the International Classification of Headache Disorders， third edition （ICHD-3）， and all patients underwent contrast-enhanced transcranial Doppler （c-TCD） and transthoracic echocardiographic right heart contrast echocardiography （cTTE） in the Third Hospital of Mianyang from January 2020 to October 2024. Basic demographic data were collected using a self-designed questionnaire， headache severity was assessed with the Visual Analogue Scale （VAS）， and sleep quality was invaluated using the Pittsburgh Sleep Quality Index （PSQI）. PFO patients was diagnosed through c-TCD combined with c-TTE. Binary logistic regression analysis was employed to examine the influencing factors of sleep quality in PFO-positive migraine patients. ResultsA total of 673 （100.00%） migraine patients were enrolled， including 223 PFO-positive cases （33.14%） and 450 PFO-negative cases（66.86%）. The PFO-positive group showed significantly more severe headache severity （χ²=15.799， P<0.01） and poorer sleep quality （χ²=14.377， P<0.01） compared with PFO-negative group. PFO-positive patients demonstrated significantly higher barrier factor scores of sleep quality， sleep latency， sleep efficiency， sleep disturbance， hypnotic medication use， and daytime dysfunction compared with PFO-negative counterparts （t=3.634， 3.269， 2.785， 3.428， 2.907， 3.637， Bonferroni adjust P<0.05/7=0.007）.By contrast， no significant difference was noted in sleep duration scores between the two groups（t=2.349， Bonferroni adjust P>0.05/7=0.007）.The Binary Logistic regression analysis revealed that age （OR=1.021， 95% CI： 1.001~1.041）， headache severity （OR=6.030， 95% CI： 4.085~8.901）， and PFO grade （OR=1.893，95% CI： 1.288~2.784）were significant influencing factors for sleep quality in migraine patients with PFO. ConclusionMigraine patients with PFO-positive exhibited poorer sleep quality compared wtih PFO-negative patients. Older age， higher headache servity， and more severe PFO grade are identified as risk factors for impaired sleep quality in PFO-positive migraine patients.

Objective To explore the technical advantages and applicable scenarios of surgical robot-assisted versus conventional freehand minimally invasive surgery for pelvic fractures by comparing clinical indicators,thereby providing evidence for clinical decision-making.Methods A retrospective case-control study was conducted on 59 patients with pelvic fractures treated with minimally invasive internal fixation between January 2022 and December 2024.Patients were divided into a conventional group(26 cases)and a robot-assisted navigation group(33 cases)based on the surgical technique.Pre-and postoperative pelvic computed tomography(CT)scans were performed,and anteroposterior,outlet,and inlet view radiographs were obtained.The maximum residual displacement after pelvic reduction and screw placement accuracy were measured based on radiographic and CT imaging.Intraoperative fluoroscopy frequency,radiation dose,operative time,blood loss,number of implanted screws,maximum residual displacement after reduction,and screw accuracy were recorded.Results No significant differences were observed between the two groups in age,gender,injury mechanism,or fracture classification,indicating comparability.Blood loss and fracture reduction quality showed no significant differences.The operative time was 52.5(30.8,62.3)min in the conventional group and 60(50,82.5)min in the robot-assisted group.Intraoperative fluoroscopy frequency and radiation dose were(19.1±5.4)times and 33.1(27.5,43.9)mGy in the conventional group,compared to(12.1±4.9)times and 123.1(101.1,131.4)mGy in the robot-assisted group.The robot-assisted group demonstrated superior screw placement accuracy,increased utilization of anterior column screws,and shorter postoperative ambulation time.Conclusion Robot-assisted minimally invasive surgery for pelvic fractures significantly outperforms conventional freehand techniques in improving screw placement accuracy and reducing radiation exposure for surgeons.It represents a preferable option for treating unstable pelvic fractures.

Objective To investigate the association between birth weight and dementia risk and the mediating roles of chronic diseases,and to assess potential biological pathways underlying the birth weight-associated dementia risk based on large-scale proteomics.Methods We used data from 279 743 participants aged 40 to 69 years enrolled in the UK Biobank.Birth weight was categorized into low birth weight(≤2 500 g),normal birth weight(2 500-3 999 g),and macrosomia(≥4 000 g).Multivariable Cox proportional hazards regression models were used to assess the associations between birth weight categories and all-cause dementia and its subtypes(Alzheimer's disease and vascular dementia).Proteomics analyses were conducted to identify proteins and the potential pathways involved.Results Low birth weight was associated with higher risks for all-cause dementia and its subtypes.The hazard ratios were 1.18(95%CI,1.08-1.30)for all-cause dementia,1.14(95%CI,1.00-1.31)for Alzheimer's disease,and 1.22(95%CI,1.01-1.48)for vascular dementia.A non-linear relationship was observed between birth weight and dementia risk(P for nonlinearity<0.001).Certain cardiometabolic diseases in middle-aged adults,such as diabetes,stroke,hypertension,and dyslipidemia,played a significant mediating role in the relationship between low birth weight and dementia risk,with the mediation proportion being 6.3%to 15.8%.Proteomic analyses identified 21 proteins linked to both low birth weight and all-cause dementia risk,which were significantly enriched in the pathways for viral protein interaction with cytokines and cytokine receptors,adipocytokine signaling,and cytokine-cytokine receptor interaction.Conclusion Low birth weight is positively associated with dementia risk.Cardiometabolic diseases in middle-aged adults may mediate the relationship between low birth weight and dementia risk.A number of proteins and the associated pathways underscore the relationship between low birth weight and dementia risk.

Objective:To explore the effects of adjuvant therapy by hyperbaric oxygen for high-energy lower limb fractures.Methods:This prospective case-control study enrolled the patients with high-energy lower extremity fracture who had been admitted to Department of Orthopaedics, Beijing Luhe Hospital, Capital Medical University from January 2021 to December 2022. Their fracture types included tibial plateau ones, pilon ones, ankle ones complicated with dislocation, and calcaneal ones. The patients were randomly divided into a control group receiving routine orthopedic treatment and a trial group receiving adjuvant therapy by hyperbaric oxygen in addition to routine orthopedic treatment using a random number table. The first adjuvant therapy by hyperbaric oxygen was conducted in the trial group within 48 h after injury before the timing for surgery was decided according to the soft tissue swelling at the affected limb. Follow-up was conducted until one year after surgery. The early and late wound complications, time from injury to surgery, and hospital stay were compared between the 2 groups.Results:A total of 160 patients with high-energy lower extremity fracture were enrolled in this study. Eventually, 7 patients were excluded, 72 patients [48 males and 24 females, with an age of (46.3±12.5) years] included in the trial group and 81 patients [61 males and 20 females, with an age of (47.8±13.4) years] in the control group. There was no significant difference in the preoperative general data between the 2 groups, indicating comparability ( P>0.05). The incidence of early wound complications in the trial group was 5.6% (4/72), significantly lower than that in the control group [18.5% (15/81)] ( P<0.05). The incidences of late wound complications in the trial and control groups were 12.5% (9/72) and 9.9% (8/81) respectively, showing no statistically significant difference ( P>0.05). The time from admission to surgery was respectively 4 (2, 8) days and 4 (2, 6) days, and the hospital stay respectively 10 (7, 14) days and 9 (6, 12) days for the trial and control groups, showing no statistically significant differences between the 2 groups ( P>0.05). Conclusion:In the treatment of high-energy lower extremity fractures, adjuvant therapy by hyperbaric oxygen can reduce the incidence of early wound complications without increasing the hospital stay, but it does not reduce the incidence of late wound complications or shorten the preoperative waiting time.
