Plate Osteosynthesis of Proximal Humerus Fracture is Associated with Significant Complications and Poor Functional Score for Patients Older than 45 Years Old: A Cohort Study

BackgroundDespite the introduction of new implants and biomechanical improvements for proximal humerus fractures (PHF), the complication rate remains significant, particularly in older adults. This study aimed to identify risk factors for complications and failure following plate osteosynthesis for PHF and discuss an age cut-off that surgeons should consider for complications. MethodsAdults with PHF treated with the proximal humerus internal locking system (PHILOS) at our large tertiary academic referral center between 2015 and 2020 were retrospectively identified. Univariate analysis was used to compare patients with and without complications. Then, a multivariate regression analysis was conducted to assess the possible complication risk factors. The receiver operating characteristic (ROC) curve of age was drawn to predict complication-free and favorable functional outcomes at the most recent follow-up. Oxford Shoulder Score (OSS) was considered favorable if OSS<10. ResultsA total of 135 patients were identified, with a mean age of 44 years (range 18-85 years) and a mean follow-up duration of 4.6 years (range 2-8 years). Complications were observed in 19 cases (14.1%), namely nonunion (n=5), avascular necrosis (n=1), infection (n=1), intra-articular screw perforation (n=1), arthritic changes (n=5), and superior humeral head migration (n=5). Eight patients (5.9%) needed revision surgery. Older age (OR=1.09) and Neer IV class (OR= 8.3) were associated with an increased likelihood of complication (P<0.001, P=0.02, respectively) in logistic multinominal regression analysis. The ROC curve for age in predicting complication-free cases had an area under the curve (AUC) of 0.829, indicating age as a significant predictor of ORIF outcomes in PHF (P<0.05). The optimalcut-off for age was 44 years, which yielded a sensitivity of 100% and a specificity of 65.7. The age ROC curve for predicting favorable OSS (OSS<10) had an of 0.829, indicating that age could predict the favorable OSS outcomes of ORIF in PHF. The optimal age cut-off was 46 years, yielding a sensitivity of 70.0% and a specificity of 78.6%. ConclusionThe outcomes of ORIF for PHF in patients older than 45 years are associated with significantly higher complication rates and poorer functional outcomes. Surgeons should possibly consider other treatment options for PHF in each older patient individually, especially with Neer type IV fractures.

The influence of healthy eating index on cognitive function in older adults: chain mediation by psychological balance and depressive symptoms

BackgroundThis study aims to investigate the relationships between the Chinese Healthy Eating Index (CHEI), psychological balance, depressive symptoms, and cognitive function in the rural older population. Additionally, it examines the impact of CHEI on cognitive function and the potential chain mediating roles of psychological balance and depressive symptoms.MethodsThe study utilized data from 2,552 rural older adults aged 65 and above, drawn from the Chinese Longitudinal Healthy Longevity Study (CLHLS). The CHEI was self-reported, with scores ranging from 0 to 50, representing adherence to healthy eating habits. Psychological balance was assessed using status and personality-emotion characteristics recorded in the database, with scores ranging from 6 to 30. Cognitive function was measured using the Mini-Mental State Examination (MMSE), with scores ranging from 0 to 30; higher scores indicated better cognitive function. Depressive symptoms were evaluated using the 10-item Center for Epidemiologic Studies Depression Scale (CESD-10), with scores ranging from 0 to 30, where higher scores reflected more severe depressive symptoms.ResultsThe median CHEI score was 40.0 (IQR: 34.0–45.0), reflecting moderate adherence to healthy dietary practices. The median Psychological Balance score was 19.0 (IQR: 17.0–21.0), and the median Depressive Symptoms score was 13.0 (IQR: 10.0–15.0), indicating mild depressive symptoms among participants. Additionally, the median Cognitive Function score was 28.0 (IQR: 27.0–29.0), suggesting relatively stable cognitive abilities within the sample. Correlational analysis revealed the following: (1) Depressive symptoms were negatively correlated with both cognitive function (rs = -0.100, p < 0.001) and CHEI (rs = -0.206, p < 0.001), as well as with psychological balance (rs = -0.142, p < 0.001). (2) CHEI was positively correlated with both cognitive function (rs = 0.144, p < 0.001) and psychological balance (rs = 0.131, p < 0.001). (3) Cognitive function was also positively correlated with psychological balance (rs = 0.096, p < 0.001). Mediation analysis demonstrated that both psychological balance and depressive symptoms partially mediated the relationship between CHEI and cognitive function, forming a chain-mediating effect.ConclusionThe Chinese Healthy Eating Index was found to have a direct positive impact on cognitive function in rural older adults. Furthermore, it exerted an indirect effect through the independent and chain-mediating roles of psychological balance and depressive symptoms. These findings suggest that dietary adherence can influence cognitive health not only directly but also by improving psychological well-being and reducing depressive symptoms.

Buyang Huanwu Decoction restores the balance of mitochondrial dynamics after cerebral ischemia-reperfusion through calcium overload reduction by the PKCε-Nampt-Sirt5 axis

Ethnopharmacological relevanceStroke is a common condition that poses a significant threat to human health. Buyang Huanwu Decoction (BYHWD) is a traditional treatment used for stroke management. However, the exact mechanism by which BYHWD mitigates cerebral ischemia-reperfusion by regulating calcium overload and restoring mitochondrial function is not yet fully understood. AimThe objective of this research was to examine the neuroprotective properties of BYHWD in reducing the damage produced by cerebral ischemia/reperfusion (I/R) injury via the modulation of calcium overload and mitochondrial dynamics (MD). MethodsMCAO/R model success was evaluated via PSI laser scatter flowmetry. The neurological function scores were assessed. The cerebral infarct (CI) volume was detected via TTC staining. NeuN expression was detected via immunohistochemistry, and degenerated neurons were observed via FJC staining. The mitochondrial permeability transition pore (mPTP), the mitochondrial membrane potential (MMP), and ATP were detected. The reactive oxygen species (ROS) content and the NAD+/NADH ratio were determined. The glutamate (Glu) and glutamine (Gln) contents as well as the Ca2+ concentration were determined. The expression of PKCε, p-PKCε, namely, Sirt5, GLS, Drp1, p-Drp1 616, Fis1, Opa1, and Mfn2 was determined via Western blotting. Immunohistochemistry was used to detect p-PKCε, which is expressed at high levels. Immunofluorescence was used to detect p-Drp1 616, Opa1 and Sirt5 fluorescence intensity. ResultsBYHWD treatment enhanced neurological function, decreased the amount of CI, mitigated neuronal damage, decreased mPTP opening, restored the MMP, increased ATP synthesis, and decreased the ROS content after brain I/R. It also increased PKCε, p-PKCε, Sirt5, GLS, Opa1 and Mfn2 expression; downregulated p-Drp1 616, Drp1 and Fis1 expression; elevated the NAD+/NADH ratio and Gln content; and decreased the Glu content and Ca2+ concentration. The effects of BYHWD were reversed by the administration of the PKCε inhibitor εV1-2. BYHWD administration led to increased PKCε mRNA expression. ConclusionsBYHWD modulates MD by diminishing calcium overload through the PKCε-Nampt-Sirt5 axis, which restores mitochondrial function and mitigates brain I/R damage.

Decision regret and satisfaction with shared decision-making in pancreatic surgery

BackgroundPancreatic surgery often does not provide long-term survival in patients with cancer or consistently improve symptoms in benign disease. This study aimed to assess decision regret and satisfaction with the decision-making process among patients who underwent pancreatectomy. MethodsThis study administered the Brehaut Decision Regret Scale (DRS), 9-Item Shared Decision-Making Questionnaire (SDM-Q-9), and the European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30) to all patients who underwent elective pancreatectomies from 2021 to 2023. Decision regret was defined as a DRS of >25. In addition, this study evaluated SDM-Q-9 responses in patients with and without regret. ResultsA total of 143 patients were included in this study, of whom 71 patients (49.6%) completed the distributed surveys. Demographics, pathology, and major complication rates were similar between responders and nonresponders. The indications for surgery were malignancy (67.6%) and benign disease (32.4%). Decision regret after pancreatic surgery was reported in 18.3% of patients. Patients who experienced regret were younger (50.8 ± 18.7 years [younger group] vs 62.0 ± 14.9 years [older group]; P = .03), more likely to have benign disease (39.1% [benign disease] vs 8.3% [malignant disease]; P < .01), underwent a distal pancreatectomy (34.5% [distal pancreatectomy] vs 7.7% [pancreaticoduodenectomy]; P = .02), or experienced a major complication (36.8% [major complication] vs 11.5% [no major complication]; P = .03). Patients with regret had lower global health (57.1 ± 20.1 [patients with regret] vs 76.2 ± 22.2 [patients without regret]; P < .01) and social function scores (61.5 ± 31.5 [patients with regret] vs 77.6 ± 22.0 [patients without regret]; P = .03) on the EORTC QLQ-C30. Patients with regret were less satisfied with the shared decision-making process. ConclusionStrong decision regret was reported in 18% of patients who underwent pancreatectomy. Younger age, distal pancreatectomy, benign indications, and major postoperative complications were associated with regret. Data from the SDM-9 highlight areas for potential improvement to help patients make decisions aligned with their goals of care.

Loganin attenuates the inflammation, oxidative stress, and apoptosis through the JAK2/STAT3 pathway in cerebral ischemia-reperfusion injury

BackgroundLoganin, a monoterpene iridoid glycoside derived from Cornus officinalis Sieb. Et Zucc, has been reported to have anti-inflammatory and antioxidant activity. Nevertheless, the potential role and molecular mechanism of loganin in cerebral ischemia-reperfusion (I/R) injury are not well-understood. The purpose of the study was to explore the functional role of loganin in the inflammation, oxidative stress, and apoptosis in cerebral I/R injury in rats Materials and methodsFollowing middle cerebral artery occlusion (MCAO), 80 mg/kg of loganin was intragastrically administered for 7 consecutive days. Neuromotor function scores were performed 24 h after the last administration, and the cerebral infarction volume was determined by TTC straining. The expressions of IL-6, IL-1β, and TNF-α in the brain tissues of MCAO rats were detected by ELISA assay. The activities of ROS, SOD, and MDA were measured by ELISA assay as well. Cell apoptosis were was tested by TUNEL straining. Western blot assay was applied for measuring the protein levels ResultsWe observed that the expressions of IL-6, IL-1β, and TNF-α were amplitude markedly elevated in the rats following MCAO. Treatment with loganin obviously reduced these expressions in the brain tissues of MCAO rats. ELISA assay showed that ROS generation and MDA activity were increased in MCAO group and it was decreased after treatment with loganin. However, loganin increased the SOD activity, which was reduced by MCAO operation. Moreover, loganin promoted neurological function improvement and inhibited cell apoptosis in the rats after MCAO. Mechanically, loganin triggered JAK2/STAT3 phosphorylation in the rats following MCAO, and activation of JAK2/STAT3 pathway rescued the inhibition effects of loganin on the inflammation, oxidative stress, and apoptosis ConclusionsThese results provide evidence that loganin may alleviate the inflammation, oxidative stress, and apoptosis through the JAK2/STAT3 pathway in MCAO rats.

Metabolite Alterations in the Left Dorsolateral Prefrontal Cortex and its Association with Cognitive Assessments in Amyotrophic Lateral Sclerosis: A Longitudinal Magnetic Resonance Spectroscopy Study.

To characterize the longitudinal metabolite profile of the left dorsolateral prefrontal cortex (DLPFC) in amyotrophic lateral sclerosis (ALS) using magnetic resonance spectroscopy (MRS) and to examine its correlation with cognitive assessments. Thirteen patients at baseline and ten at follow-up, along with 14 age-, sex-, and handedness-matched healthy controls (HCs), were recruited. Three Tesla with a 64-channel coil, Point-RESolved Spectroscopy (PRESS) sequence (TR=1500 ms and TE=140 ms) was used. Metabolites in the left DLPFC were quantified using LCModel. Cognitive performance and functional impairment were assessed using the Edinburgh Cognitive and Behavioral ALS Screen (ECAS) and Revised ALS Functional Rating Scale (ALSFRS-R), respectively. Group comparisons were adjusted for multiple comparisons (p < 0.05, Bonferroni correction). The links between the brain metabolites and cognitive function were investigated using relevant correlation tests (Pearson's or Spearman's). Our analysis revealed a significant difference in the choline-to-creatine ratio (tCho/tCr) among the three groups. Baseline ALS patients showed a higher tCho/tCr ratio than HCs (p = 0.033, Bonferroni-corrected). Interestingly, the total N-acetyl aspartate (tNAA)/tCr ratio, a marker of neuronal health, was strongly positively correlated with visuospatial cognitive scores at baseline and follow-up. Furthermore, at follow-up, tNAA/tCr was positively correlated with the total scores and specific sub-scores on the ECAS, encompassing both ALS-specific and non-specific cognitive domains. At follow-up, positive correlations emerged between tNAA/tCr and the total language and executive function scores. Metabolite alterations and correlations with cognition were observed in the left DLPFC of ALS patients, supporting extra-motor involvement and its association with cognitive decline.

The effectiveness and safety of botulinum toxin injections for managing motor disorders of patients with Parkinson's disease: A meta-analysis of randomized controlled trials.

This study aimed to assess the effectiveness and safety of botulinum toxin (BTX) injections for managing motor disorders in patients with Parkinson's disease (PD). An electronic search was conducted based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Data from available randomized controlled trials (RCTs) assessing BTX injections for motor disorders in PD patients were extracted for meta-analysis. Ultimately, 215 patients from eight RCTs were enrolled. Pooled analyses indicated that BTX was more effective than placebo in improving tremor (standardized mean difference [SMD] = 0.96, 95% CI [0.34, 1.58], p < 0.01), whereas no notable differences were observed between BTX and placebo regarding freezing of gait (SMD = 0.66, 95% CI [-0.26, 1.58], p = 0.162), United Parkinson's Disease Rate Scale (UPDRS) III score (SMD = -0.20, 95% CI [-1.17, 0.76], p = 0.68) and clinical global impression (CGI) score (SMD = 0.84, 95% CI [-0.74, 2.42], p = 0.298). Adverse events related to BTX injections were comparable to placebo (OR = 1.74, 95% CI [0.59, 5.14], p = 0.32). The current evidence suggests that BTX is effective and safe in treating PD tremor but fails to provide therapeutic benefits for freezing of gait and motor functional scores in PD patients. Furthermore, the limited number of included studies and heterogeneity in BTX intervention protocols suggest more research is needed, with additional standardized RCTs, to better understand and optimize BTX injections for motor disorders in PD.

Open and all-inside arthroscopic Brostrom-Gould for chronic lateral ankle instability: a comparative analysis of surgical outcomes and learning curves

ObjectiveThe purpose of this study was to investigate and compare the learning curve and clinical outcomes of all-inside arthroscopic and open techniques in the treatment of chronic lateral ankle instability (CLAI). MethodThis was a retrospective cohort analysis of 100 consecutive patients who received all-inside arthroscopic or open Brostrom-Gould surgery. These patients with CLAI were all surgically treated by the same surgeon. We applied the CUSUM analysis to assess the surgeons' learning curves, determine the cut-off point, and subsequently divide the patients into learning and proficiency groups. We recorded and compared baseline data, the preoperative and postoperative clinical function scores (AOFAS, K-P, and Tegner scores), VAS scores, time to full weight-bearing, surgery-related parameters (operation time, and postoperative hospital stays), and complications for both surgical methods during their learning and proficiency phases. ResultThe CUSUM analysis identified a learning curve cutoff at 12 cases for open surgery and 22 cases for arthroscopic surgery. In the open surgery group, significant differences were observed in operation time between the learning and proficiency phases (P<0.05). However, no significant differences were found in clinical function scores and postoperative full weight-bearing time. Similar trends were seen in the arthroscopic surgery group, with significant improvements in operation timeand postoperative hospitalization time in the proficiency phase compared to the learning phase (P<0.05). However, no significant differences were found in clinical function scores between either surgical method's learning and proficiency stages. Additionally, when comparing the two surgical approaches at the same stage, significant differences emerged in VAS scores, postoperative full weight-bearing time, operation timeand postoperative hospitalization time (P<0.05), with the arthroscopic technique showing advantages in reduced postoperative discomfort and faster recovery times. ConclusionAlthough arthroscopic surgery takes longer to achieve proficiency, it offers the advantages of reduced postoperative discomfort and faster recovery times during both the learning and proficiency phases while achieving comparable clinical outcomes.

Shengji ointment combined with bromelain promotes granulation of exposed tendons in diabetic foot ulcers: A multicenter, randomized, positive-controlled clinical trial

BackgroundExposed, infected and necrotic tendons often occur in the middle and late stages of diabetic foot ulcers (DFUs). The exposed tendon is both a potential source and route of infection, which prolongs the treatment period and affects recovery, leading to amputation and even death. Therefore, management of the exposed tendon in patients with DFU is the key to treatment. This study aimed to evaluate the clinical efficacy of Shengji ointment combined with bromelain in the treatment of DFU with tendon exposure and to provide clinical treatment options and evidence-based medicine. MethodsThis study was a multicenter, nonblinded, randomized, positive controlled clinical trial involving 180 patients with DFU with tendon exposure at four tertiary-grade A-class hospitals. The included patients were randomly assigned 1:1 to an observation group (n = 90) that received Shengji ointment combined with bromelain and a control group (n = 90) that received hydrocolloid dressing, with dressing changes once daily for 4 weeks. Patients in both groups continued with conventional treatments, such as blood glucose and blood pressure medication, lipid regulation, and antiplatelets. The primary outcome measure was wound coverage with granulation tissue. The secondary outcome measures included the wound healing rate, time to granulation, Maryland foot score, time to debridement of necrotic tendon tissue, and granulation tissue score. We performed measurements before enrollment and after the end of treatment for comparison. ResultsThere was no significant difference in the baseline data between the two groups before treatment (P > 0.05). After treatment, the primary outcome indicators of the two groups were compared, and the wound granulation tissue coverage rate of the treatment group was greater than that of the control group (P = 0.003). For the secondary outcome outcomes, the wound healing rate, time to granulation, Maryland foot function score, time to debridement of necrotic tendon tissue, and granulation tissue score in the treatment group were significantly better than those in the control group (P < 0.05). There was no significant difference in the incidence of adverse reactions between the two groups (P = 0.444). ConclusionsShengji ointment combined with bromelain effectively promotes the removal of exposed necrotic tendons in patients with DFU, promotes the regeneration of healthy granulation tissue, accelerates wound healing, and protects the limb and its function. It also appears to be safe as an intervention for the treatment of patients with DFU. Trial registrationThe study protocol was registered in the Chinese Clinical Trial Registry (ChiCTR) under the code ChiCTR2000039327 on October 23, 2020. The public title is “Study on evidence-based evaluation and therapeutic mechanism of integrated Chinese and Western medicine for treatment of diabetic foot - An evidence-based evaluation of The combination of Rubber Shengji Paste and compound bromelain to promote the healing of the exposed wound of diabetic foot tendon”.

Comparison of the MIPPO technique and the modified Stoppa approach in the treatment of unstable anterior pelvic ring injuries: a retrospective cohort study

BackgroundAnterior pelvic ring injuries have gradually become common. Using a minimally invasive technique to treat this injury may be feasible if the reduction and stability can be effectively achieved. We describe a percutaneous technique, minimally invasive percutaneous plate osteosynthesis (MIPPO), to fixate the anterior pelvis via establishing a subperiosteal tunnel between two limited incisions over the iliac crest(s) and pubic ramus in this research.MethodsA retrospective cohort study comparing the MIPPO technique (n = 60) versus the modified Stoppa approach (n = 53) for anterior pelvic ring injuries with posterior ring instability was performed from September 2016 to January 2023. The relative surgery variables, follow-up function evaluation, and complications were compared in two groups. The reduction quality of fracture was assessed according to the Matta criterion, and the functional score was evaluated using the Majeed score.ResultsAll patients completed follow-up, with an average interval of 39.90 ± 17.53 months (range 12–78). In the MIPPO technique group, the surgery interval and blood losses were lower compared to the modified Stoppa approach group (P<0.05). The mean procedure times and intraoperative blood losses were 69.56 ± 14.04 min/side (range 50–110) and 156.23 ± 49.75 mL/side (range 90–250) for unilateral anterior ring MIPPO fixation separately. All patients got a satisfactory reduction of the fracture. In the follow-up, earlier ambulation, shorter postoperative hospital stays, and lower complication rates were observed for patients using the MIPPO technique compared to the modified Stoppa approach (P<0.05). However, there is no statistical difference in these indicators including fracture union interval, full load time, the Majeed score, patient satisfaction level, and return to pre-injured work rate between the two groups.ConclusionThis clinical experience gives support for the use of the MIPPO technique to stabilize the anterior pelvis. This minimally invasive technique was an effective and safe surgery method and could obtain satisfactory function results, particularly fitting to part of patients with resistance using the modified Stoppa approach.

Predict the musculoskeletal injuries in young skaters using Functional Movement Screen (FMSTM)

Background. Skating is a great way to improve heart rate, coordination, and strengthen the muscles, and burn calories. It works on the muscles of the legs, gluteus, and core and causes 50% less stress to the joints than running, along with improving flexibility and endurance. The FMS™ is a clinical screening tool used to assess seven fundamental movement patterns. It consists of overhead deep squats, hurdle steps, inline lunges, straight leg raises, trunk stability pushups, shoulder mobility, and rotary stability. Injuries are more common in sports, especially skating, where balance and coordination are required. A study like this is necessary to screen skaters, help predict injuries, and train them accordingly to prevent injuries. Objective. The objective is to predict musculoskeletal injuries in young skaters using the Functional Movement Screen (FMS™). Methodology. This is an observational cross-sectional study. Sixty-four skaters of both genders, aged between 6 and 18 years, were conveniently selected based on the inclusion and exclusion criteria and were assessed using FMS™. Outcome measures. Functional Movement Screening scores. Results. 31.3% of young skaters scored between 0 and 13 and are at high risk for musculoskeletal injuries, while 68.8% are at a low risk of injury with FMS™ scores ranging from 14 to 21. Conclusion. This study concluded that 31.3% of young skaters have a high risk for musculoskeletal injuries according to the Functional Movement Screen.

MCL augmentation using a peroneus longus split tendon autograft satisfactorily restores knee stability with no impairment in foot function and with a low failure rate for concurrent ACL reconstruction.

Addressing grade 2 and 3 medial-sided instabilities during anterior cruciate ligament (ACL) reconstruction is crucial to reduce the risk of ACL graft failure. This study introduced a minimally invasive, medial collateral ligament (MCL) augmentation technique using a peroneus longus split tendon autograft, which was fixed to the femoral deep MCL insertion and tibial superficial MCL insertion. This prospective, longitudinal, single-centre case series included patients who underwent MCL augmentation concurrent with primary or revision ACL reconstruction due to anteromedial instability. Preoperatively and at 1-year follow-up, clinical examinations, such as rolimeter test of anterior tibial translation and medial instability, knee (International Knee Documentation Committee subjective knee form [IKDC], Lsyholm, Knee Injury and Osteoarthritis Outcome Score [KOOS]) and foot function scores (American Orthopaedic Foot and Ankle Society score [AOFAS]) and complications, were analyzed. Thirty-one patients with a mean follow-up of 13.5 ± 2.6 months and a mean age of 27.8 ± 9.6 years were included. The side-to-side difference for anterior tibial translation significantly improved from preoperative to 1-year follow-up with an ACL reconstruction failure rate of 6.5%. No patient retained a grade 2 or 3 medial instability on valgus stress testing with 30° flexion. Significant improvements from preoperative to 1-year postoperative follow-up were observed in knee function scores: IKDC (48.9 ± 26.9- 71.3 ± 11.5, p < 0.001) and Lysholm (59.9 ± 28.5-80.5 ± 11.2, p = 0.002) as well as KOOS pain, ADL, sport and QoL, each reaching the respective minimal clinically important difference values. The foot function score AOFAS showed no significant impairment (100 ± 0-99.3 ± 2.5, p = 0.250). Complications included cyclops lesions of ACL reconstruction in three patients. At 1-year follow-up, MCL augmentation using a peroneus longus split tendon autograft for patients simultaneously undergoing ACL reconstruction satisfactorily restores knee stability, has a low ACL reconstruction failure rate and does not significantly impair foot function. Level IV therapeutic study; case series.

Does robotic surgical assistant (ROSA) functionally aligned TKA lead to higher satisfaction than conventional mechanically aligned TKA: A propensity-matched pair analysis

ObjectivesTotal knee arthroplasty (TKA) is the established treatment for severe knee osteoarthritis, with robotic-assisted TKA (rTKA) proposed to enhance surgical precision and potentially improve outcomes. This study investigates whether functionally-aligned rTKA using the ROSA Knee System results in superior functional outcomes and patient satisfaction compared to conventional mechanically aligned TKA (mTKA). MethodsWe conducted a retrospective, propensity-score matched cohort study including 154 patients (46 rTKA, 108 mTKA) who underwent primary TKA by a single surgeon from October 2020 to October 2023. Functionally-aligned (FA) rTKA was performed using the ROSA Knee System. Patients were assessed using the Short-Form 36 (SF36), Knee Society Knee Score (KSKS), Knee Society Function Score (KSFS), and Oxford Knee Score (OKS) preoperatively and at 6 months postoperatively. Immediate postoperative outcomes such as pain at rest and movement, ambulation distance, and range of motion were measured. Statistical analysis evaluated results at a 95 % confidence interval, with significance at P < 0.05. ResultsNo significant differences were observed in immediate postoperative pain at rest (P = 0.988), pain during movement (P = 0.634), ambulation distance (P = 0.243), and range of motion (P = 0.752) between the groups. At 6 months, there were no significant differences between rTKA and mTKA in achieving the minimal clinically important difference for SF36 (P = 0.996), KSKS (P = 0.150), KSFS (P = 0.091), and OKS (P = 0.949). No significant differences were noted for satisfaction levels (P = 0.315) and fulfilled expectations (P = 0.557) between both groups. ConclusionsAt 6 months postoperatively, FA rTKA demonstrated equivalent outcomes and satisfaction levels compared to mTKA. Future research should focus on examining longer-term follow-up outcomes, quantifying gap balance in MA mTKA to allow direct comparison with rTKA and studying alternative personalised alignment rTKA strategies to enhance patient outcomes.

Association between CD20+ T lymphocytes and neuropsychological findings in multiple sclerosis.

CD20+ T lymphocytes are a subset of circulating T cells presenting the CD20+ receptor, a molecular marker of B lineage. CD20+ T lymphocytes are thought to play a pivotal role in multiple sclerosis (MS) pathology, especially at progressive stages. We aimed to investigate the correlation between CD20+ T lymphocytes and neuropsychological features (i.e., cognition, depression, anxiety, fatigue, and sleep quality) in MS patients. We enrolled 90 MS patients. Each patient underwent cognitive assessment (Brief International Cognitive Assessment for Multiple Sclerosis) and psychometric assessment (modified Fatigue Impact Scale, Beck Anxiety Inventory, Beck Depression Inventory, Pittsburgh Sleep Quality Index). Cognitive status was defined through the cerebral functional score. Forty-four of 90 patients were relapsing-remitting (49%) and 46 were progressive patients (51%). Seventy patients (18.9%) showed CD20+ T lymphocytes in peripheral blood with a mean level of 0.38 ± 1.2%. Patients with CD20+ T lymphocytes were more likely to be at progressive phases (76.5% vs. 23.5%, p = 0.02) and showed a higher Expanded Disability Status Scale score (median [range] = 6.0 [1.5-7.5] vs. 3.5 [1-7.5], p = 0.001). Moreover, patients with CD20+ T lymphocytes showed worse cognitive functioning (p = 0.004), higher global fatigue symptoms (p = 0.02), higher cognitive fatigue (p = 0.01), higher psychosocial fatigue (p = 0.005), and a trend toward worse sleep quality (p = 0.06). The presence of CD20+ T lymphocytes in the peripheral blood of MS patients was associated with worse neuropsychological functioning and progressive disease stages. Peripheral CD20+ T lymphocytes could potentially serve as markers for both disease progression and development of fatigue in MS patients.

Assessment of health-related quality of life of children with idiopathic nephrotic syndrome and their caregivers in China

AimsThe primary aim of this study was to characterize the health-related quality of life (HRQoL) and identify the associated factors among children aged 2 to 18 in China diagnosed with idiopathic nephrotic syndrome (INS). Additionally, the study aimed to evaluate the HRQoL and caregiving burden of their caregivers and investigate the correlation between the HRQoL of the children and that of their caregivers.MethodsThis study recruited 181 children diagnosed with INS from Children’s Hospital, Zhejiang University School of Medicine in China. The proxy-reported PedsQL Generic Core Module (PedsQL™ 4.0 GCM) was used to measure the HRQoL of children, and the EuroQol five-dimensional questionnaire, five-level version (EQ-5D-5L) was applied to measure caregivers’ HRQoL. Differences in scale scores and total scores of PedsQL™ 4.0 GCM were assessed using t-tests and one-way ANOVA. Multivariate linear regression analysis was used to identify the factors associated with children’s HRQoL. Pearson correlation analysis evaluated the correlation between children’s HRQoL and caregiver’s HRQoL.ResultsHRQoL of Children with INS declines with increasing age, and children aged 5-18 had lower scores in physical functioning, emotional functioning, school functioning, psychosocial health summary score, and total PedsQL™ 4.0 GCM score compared to healthy children. Various factors, including the mother filling out the questionnaire, the father being unemployed, and the use of other medications except for steroids, were associated with worse HRQoL of children (p values < 0.05). Additionally, a correlation exists between children’s HRQoL and their caregivers’ HRQoL.ConclusionThis study evaluated the HRQoL of children aged 2-18 years diagnosed with INS in China, along with the HRQoL of their caregivers. Multiple factors potentially influence the HRQoL of children. A significant correlation was observed between the HRQoL of children and their caregivers, who frequently experienced varying levels of caregiving burden. Therefore, it is recommended that healthcare professionals prioritize optimizing HRQoL for children with INS and their caregivers.

Percutaneous hollow nail internal fixation treatment for fractures of the pubic symphysis and its adjacent areas.

To explore the percutaneous minimally invasive treatment of pubic symphysis and its adjacent fractures. Since May 2021, 13 cases of fractures involving the pubic symphysis and its adjacent parts were treated with x-ray fluoroscopic localization and percutaneous cannulated screw fixation across the symphysis pubis, the guide pin pierced the symphysis pubis and the fracture end and stopped at the inner edge of the acetabulum. Visual analogue scale (VAS) was used to evaluate the effect of the operation, and the patients were followed up. The screw insertion operation time was 25-40 min, with an average of 31.45 min; The number of perspectives is 20-40, with an average of 28.75. The average intraoperative blood loss was 10 ml, and there were no puncture complications such as nerve or vascular damage. The initial stability of the fractured end of the patient after surgery was good. The VAS score decreased from preoperative 8-10 points to postoperative 1-2 points (average of 1.5 points). The follow-up time was 3-25 months, with an average of 8.5 months. At the last follow-up, the excellent and good rate of pelvic function according to Majeed pelvic function scoring system was 100%. One patient had screws removed 1.5 years after surgery, while the remaining twelve patients did not have screws removed. All patients did not experience any discomfort symptoms caused by pubic symphysis fixation. Percutaneous hollow nail internal fixation is an effective method for treating fractures of the pubic symphysis and its adjacent parts.

New evidence on patella resurfacing in modern total knee arthroplasty for all inflammatory arthritis in a mixed Asian population

BackgroundTraditional teaching advocates for routine patella resurfacing (PR) during total knee arthroplasty (TKA) in patients with inflammatory arthritis. However, evidence on this topic remains limited in the Asian population. This study aims to evaluate the postoperative outcomes and complication of patella resurfacing (PR) during primary total knee arthroplasty (TKA) in Asian patients with inflammatory arthritis. MethodsA retrospective analysis was conducted using registry data from our institution. Patients with inflammatory arthritis who underwent primary TKA from August 2017 to December 2021 were included in the study. Patients were divided into two groups - patella resurfaced (PR, n = 25) and non-resurfaced patella (PNR, n = 31) groups. Demographics, operative data, patient reported outcome measures, and complications were compared. ResultsPreoperative range of motion (ROM) (PR:95.3 ± 23.6° vs PNR:105 ± 19.5°, p = 0.106), Knee Society Scoring System Knee score (KS-KS) (PR:44.6 ± 17.4 vs PNR:49.3 ± 17.7, p = 0.331) and Knee Society Function Score (KS-FS) (PR:40.9 ± 27.3 vs PNR:47.7 ± 27.0, p = 0.325) and Oxford Knee Score (OKS) (PR:25.0 ± 7.8 vs PNR:23.3 ± 10.3, p = 0.525) were similar in both groups. Outcomes between PR and PNR groups at the one-year mark in terms of ROM (PR:112.7 ± 18.1 vs PNR:114.6 ± 16.5, p = 0.455), OKS (PR:41.5 ± 3.9 vs PNR:41 ± 4.7, p = 0.954), KS-KS (PR:84.5 ± 13.2 vs PNR:89.2 ± 9.3, p = 0.095) and KS-FS (PR:73.6 ± 18.3 vs PNR:78.7 ± 19.3, p = 0.173) were also similar. Intraoperative complication (PR:0/25 vs PNR: 3/31 (9.6 %), p = 0.245) and re-operation rates (PR: 1/25 (4 %) vs PNR: 1/31 (3.2 %), p = 0.877) were also similar in both groups. ConclusionThis study conducted on a mixed Asian population with inflammatory arthritis demonstrated that the one-year postoperative ROM and functional outcomes, complication, and re-operation rates between PR and PNR groups were similar. Hence, routine patella resurfacing on all Asian patients with inflammatory arthritis undergoing TKA may not be necessary.

Analysis of the Status Quo and Influencing Factors of Advanced Lung Cancer Patients’ Quality of Life

Objective: To investigate the quality of life and related influencing factors of patients with advanced lung cancer. Methods: A cross-sectional survey was conducted on 51 patients with advanced lung cancer who were hospitalized in the Department of Oncology from January 2023 to December 2023, and the influencing factors of patients’ quality of life were analyzed. Results: Among the five functional scales (physical, role, cognitive, emotional, and social functioning) of the QLQ-C30 scale, the social and emotional function scores were the lowest, respectively 16.7 (IQR: 0, 33.3) points, and 16.7 (IQR: 8.3, 25), and among the three symptom scales (fatigue, pain, nausea and vomiting), the fatigue symptom score was the highest: 77.7 (IQR: 66.7, 88.9) points. The results of Spearman correlation analysis showed that the anxiety score of patients with advanced lung cancer was positively correlated with depression score (P &lt; 0.01), while the quality of life of patients with advanced lung cancer was not correlated with anxiety and depression score (P &gt; 0.1). The self-care ability, the nature of the disease, and whether the patient was treated for chemotherapy were the independent influencing factors of the patient’s quality of life, and the difference was statistically significant (P &lt; 0.001). Conclusion: Patients with advanced lung cancer have different degrees of anxiety and depression, and their quality of life is affected by many factors, which are mainly related to the patient’s self-care ability, the nature of the disease, and whether they received chemotherapy.

Integrated, person-centred care for patients with complex cardiovascular disease, diabetes mellitus and chronic kidney disease; a randomized trial

Abstract Background Patients with cardiovascular disease (CVD), diabetes mellitus (DM), and chronic kidney disease (CKD) often experience fragmented care, which negatively impacts outcomes and health-related quality of life (HRQoL). This study assessed whether multidisciplinary, person-centred care at an integrated clinic improves clinical outcomes and HRQoL. Methods This prospective, open, blinded-endpoint trial (CareHND; NCT03362983) included 131 patients with CVD, DM, and CKD stages 3–4, most of whom were enrolled during or shortly after acute hospitalization. The intervention group received person-centred care from cardiologists, nephrologists, endocrinologists, and specialist nurses at an integrated clinic; the control group received traditional care from separate specialists. Primary disease progression outcome was the composite of major adverse renal and cardiovascular events (MARCE) including death, heart failure (HF) readmission, myocardial infarction, PCI/CABG, acute or end-stage kidney failure, or TIA/stroke at 2 years. Co-primary person-centred outcomes was self-reported HRQoL by RAND-36. Results In a pre-specified interim analysis, patients randomized to integrated care had lower eGFR and higher NT-proBNP than traditional care. Follow-up ranged from 2.0 to 5.7 years. Kaplan-Meier analysis showed no difference in MARCE between groups. Cox-regression adjusting for baseline differences, indicated a trend towards reduced HF hospitalisations for integrated care (HR 0.53; CI 0.28–1.01; P = 0.054). Integrated care improved Role Physical and Social Function scores, and self-rated health (P = 0.021, P = 0.019, and P = 0.011, respectively). Conclusions Integrated care improved several dimensions of HRQoL but did not improve MARCE compared to traditional care in this small trial. We observed a trend towards reduced HF hospitalizations. Overall, integrated care presents a promising alternative.

Quantitative myocardial blood flow distribution derived from CCTA and determination of myocardium at risk in the FAST TRACK CABG trial

Abstract Background In the anatomic SYNTAX score derived from invasive coronary angiography, the ischemic impact of each stenotic coronary segment is weighed with a fixed score based on the severity of luminal diameter narrowing and the theoretical amount of blood flow supplied to the myocardium(1). This method neither accounts for individual variation nor reflects the true extent of myocardium ischemia. Purpose We aim to provide a quantitative CT SYNTAX score derived from coronary computed tomography angiography (CCTA) with customized percent blood flow distribution to the myocardium supplied by each stenotic coronary segment to determine the myocardium at risk of ischemia. Methods Patients with 3VD and/or left main coronary artery disease (CAD) were included in the first-in-human FAST TRACK CABG trial and received surgical revascularization guided solely by CCTA and fractional flow reserve derived from CCTA (FFRCT). The recently reported anatomic CT-SYNTAX score was calculated for all cases. The FFRCT value and percent myocardial blood flow distribution(%MBF) were computed for all 16 SYNTAX score segments using the validated method of Keulards et al(2). On the pre-CABG CCTA, the segments located distal to the site where the FFRCT value dropped below 0.80 were considered at risk of ischemia, and the individual weight point per segment was calculated as 6×%MBF for each segment. The SYNTAX score derived from %MBF is compared to the anatomic and functional CT-SYNTAX score. Results Out of 114 patients enrolled, FFRCT and %MBF were analyzable in 106 patients. After excluding vessels with total occlusion, the coronary flow distribution between the right and left coronary systems was 20.5% vs 79.5%, respectively, similar to the 1:5 ratio in the anatomic SYNTAX score. The anatomic and functional CT-SYNTAX scores were 43.6 and 41.1, respectively. The average total %MBF per patient was 72.0(19.1)%, and the average SYNTAX score derived from %MBF was 38.0. There is a strong correlation between functional SYNTAX score and SYNTAX score derived from %MBF (Peason’s R=0.93). Passing-Bablock regression trends showed that the functional SYNTAX score slightly overestimated the SYNTAX score derived from %MBF (Figure 1). The coronary segment weight varied significantly per individual, especially in the presence of total occlusion. Overall, the fixed weight of the anatomic SYNTAX score is a good surrogate for the individualized weighing based on %MBF (Figure 2). Conclusion CCTA-derived %MBF enabled clinicians to quantify the individualized myocardium at risk of ischemia or injury in patients with severe CAD. Retrospectively, the fixed weight score used in the anatomical SYNTAX score appeared to be a robust surrogate for myocardial blood flow distribution.Figure 1Figure 2
