Granulomatosis With Polyangiitis (Wegener's) Nasal Reconstruction: Improved Outcomes With No Surgical Delay.

Granulomatosis with polyangiitis (Wegener's) causes progressive nasal collapse, nasal obstruction, and central face deformity. It is not known whether cartilaginous nasal reconstruction should be performed immediately or delayed (after disease 'burn-out'). For Wegener's nasal collapse to: (1) Assess the functional and aesthetic outcomes following immediate versus delayed nasal reconstruction; (2) Measure the impact of psychosocial well-being (anxiety, depression, social isolation) in immediate versus delayed nasal reconstruction. Wegener's patients were compared with either 1) immediate or 2) delayed nasal surgery (n = 61). Functional and aesthetic severity were compared with the validated Standard Cosmesis and Health Nasal Outcome Survey (SCHNOS) score (student's t-test). In addition, Patient-Reported Outcomes Measurement Information System (PROMIS) perioperative/1-year follow-up surveys were analyzed. At initial consultation, SCHNOS score severity types were similar for each group (Immediate vs Delayed): Mild (15% vs. 15%), Moderate (59% vs. 60%), and Severe (26% vs. 25%). Over a 30 ± 4 month wait, Delayed Surgery patients' conditions deteriorated with a shift from mild to more severe SCHNOS scores: Initial consultation vs. Prior to surgery (25 to 85). PROMIS scores at presentation were high compared to the general public; by the time of Delayed Surgery, patients significantly worsened: Anxiety (28 to 73), Depression (18 to 62), and Social Isolation (20 to 80). Although both immediate and delayed groups improved after surgery in functional and psychosocial scores, the immediate group was superior. Data showed superior functional/aesthetic scores, and superior psychosocial indicators with immediate cartilaginous nasal reconstruction compared to waiting until disease 'burn-out'.

Functional Oral Intake in Primary Versus Salvage Laryngectomy.

Advanced-stage laryngeal squamous cell carcinomais treated with primary surgery or chemoradiation. We aim to determine if there are differences in postoperative functional oral intake in primary (PL) versus salvage laryngectomees (SL). Retrospective cohort study. Patients who underwent laryngectomy between 2011 and 2021. We examined demographic, diagnostic, treatment, and swallow function data pre- and postoperatively. A follow-up survey was distributed to assess current swallow status. One hundred twenty-five patients were included. Preoperatively, 68.8% of patients reported dysphagia. Median functional oral intake score (FOIS) was 4.0 [interquartile range, IQR: 1.0-6.75]. The SL group had lower preop FOIS [2.0; IQR: 1.0-4.75] that did not reach significance compared to the PL group [4.5; IQR: 1.0-7.0] (P = .052). 73.4% of patients had a feeding tube. The PL group was more likely to have the tube removed [odds ratio, OR: 2.4; confidence interval, CI: 1.0-5.7]. The SL group was more likely to require feeding tube placement more than 6 months postop [OR: 6.9; CI: 1.65-32.6]. SL FOIS scores improved by 3 months postop to 5 (SL ΔFOIS = 3, P = .0150). PL scores improved to 7 [PL ΔFOIS = 2, P = .0005] at 12 to 15 months. Sixty-nine patients were contacted for a follow-up survey and 16 completed this survey. 30.4% patients reported dietary restrictions (mean 4.4 years postop). Patients undergoing SL appear to obtain similar swallow outcomes compared to PL at 3 to 6 months postlaryngectomy, but plateau. The PL group continues to improve up to 1 year postoperatively. Fifty percent of patients report on-going dysphagia after 5 years.

The Multifaceted Burden of Respiratory Syncytial Virus (RSV) Infections in Young Children on the Family: A European Study.

Since the majority of hospitalisations due to RSV occur in young children, the illness profoundly influences the entire family. However, comprehensive evidence regarding its overall effects remains limited. The ResQ Family study aims to investigate the burden of RSV-induced pediatric hospitalisation on affected families. Spanning the 2022-2023 RSV season, an interdisciplinary, observational study was conducted in Germany, France, Italy and Sweden. Using an online questionnaire, parents and caregivers of children (< 24months of age) with an RSV-induced hospitalisation were recruited. Information was gathered on topics related to RSV and parental health-related quality of life (HRQoL) during the acute infection phase (t0) and 6weeks later (t1). Descriptive evaluations of the data set were performed during t0 and regarding a potential change over the observation period (t0 vs. t1). Subgroup analysis aimed to further identify differences across the countries. A total set of 138 affected parents/caregivers were included in the study, with 59 participants responding to the follow-up survey (t1). Particularly during the acute infection phase, parental HRQoL was shown to be negatively influenced by the child's RSV infection [total score (p < 0.001, d = 0.54), parent HRQoL summary score (p < 0.001, d = 0.67) and family functioning summary score (p = 0.007, d = 0.33)]. Significant disparities in disease awareness and support structures were observed across Europe, with France and Sweden showing notably higher levels. The ResQ Family study provides convincing evidence that RSV-associated hospitalisations in young children across Europe generate a multifaced burden for the entire family, partly even beyond the acute infection phase. Standardised approaches for disease prevention at societal, educational and policy levels are needed to guarantee every newborn the best possible start into life.

Mediation of White Matter Alterations in the Association Between Ventricular Dilation and Cognitive Decline in Hydrocephalus Patients: An MRI Study.

Cognitive impairment is commonly observed in hydrocephalus patients. Ventricular enlargement compresses brain parenchyma, especially the white matter (WM). To investigate whether the relationship between ventricular dilation and cognitive decline in hydrocephalus patients is mediated by WM alterations. Retrospective. 51 communicating hydrocephalus patients (median age, 54 years), 50 obstructive hydrocephalus patients (median age, 49 years), and 53 control subjects (median age, 50 years). Diffusion tensors imaging, 3D T1 BRAVO, 3D FIESTA, CUBE T2, and FLAIR sequences at 3T. DTI parameters (skeletonized fractional anisotropy (FA), skeletonized mean diffusivity (MD), and peak width of skeletonized mean diffusivity p(PSMD)) were extracted using FSL software. Global, periventricular, and deep white matter hyperintensity (WMH) volumes, degree of ventricular enlargement (Evans index), and other conventional imaging markers (number of lacunes and perivascular spaces, intracranial and brain volume) were extracted using united imaging intelligence. Cognitive tests included Montreal cognitive assessment (MoCA), clock drawing test (CDT), and vocabulary fluency test (VFT). Multivariable linear regression analysis, mediation analyses, and dominance analysis. P-value <0.05 was considered significant. The degree of ventricular dilation, DTI parameters, and cognitive function scores were interrelated. The skeletonized FA values (β = -0.0917, 95% confidence interval (CI): -0.205, -0.024) and normalized global WMH volume (β = -0.0635, 95% CI: -0.13, -0.0005) together mediated 37.2% of the association between Evans index and MoCA. A comparable causal pathway was found for periventricular WMHs but not for deep WMHs. Dominance analysis indicated skeletonized FA values had a greater impact on cognition than WMH volume. The skeletonized FA values also mediated the association between Evans index and CDT (β = -0.0897, 95% CI: -0.165, -0.026) and VFT (β = -0.1589, 95% CI: -0.27, -0.083). WM alterations were causal mediators between ventricular dilation and cognitive decline in hydrocephalus patients. 3. Stage 3.

Surgical management and functional outcomes of perilunate dislocations and fracture dislocations through the dorsal approach.

Perilunate dislocations and perilunate fracture dislocations (PLD/PLFDs) are rare injuries of the wrist, with surgical management leading to acceptable functional results. The purpose of this study was to assess the functional outcomes of the patients of our department who were treated with surgical management of PLDs/PLFDs through dorsal approach, as well as to report any complications on their follow-up. In this retrospective study, 52 patients with PLD/PLFD, fulfilling the inclusion and exclusion criteria of the study, underwent surgical management of their injury. All patients were followed up at 6weeks, 12weeks, 6months, 1year postoperatively with radiographic imaging as well as functional scores measured with the modified mayo wrist score and the QuickDASH questionnaire. The mean postoperative modified Mayo score was 76.8 ± 8.8 and the mean QuickDASH score was 1.52 ± 2.18. Of the 52 cases, 20% had excellent results, 42% had good results, 29% had fair results and 9% had poor results as per the modified Mayo wrist score. No patient signed any symptoms of median nerve neuropathy. In conclusion, open reduction and internal fixation through dorsal approach is a reliable technique to manage perilunate injuries in spite of radiological evidence of wrist arthritis, as it also provides consistently good results in terms of functional outcomes. Retrospective case series study.

The impact of comorbidity status on knee function 1 year after total knee arthroplasty: a population-based cohort study.

Few studies have examined the impact of comorbidity on functional and clinical knee scores after primary total knee arthroplasty (TKA). We compared the effect of having a high Charlson Comorbidity Index (CCI), relative to a low CCI, on changes in the American Knee Society Score (AKSS) functional and clinical scores from baseline to week 52 after TKA in patients with knee osteoarthritis (OA). This population-based cohort study included 22,533 patients identified in the Danish Knee Arthroplasty Register from 1997 to 2021. Patients were classified as having low, medium, or high comorbidity based on CCI. The outcome was defined as the mean change (from preoperative to 1-year post-TKA) in functional and clinical knee scores measured by the AKSS (0-100). The association was analyzed using multiple linear regression by calculating mean change scores adjusting for sex, age, weight, cohabiting status, and baseline AKSS. The prevalence of patients with low, medium, and high comorbidity was 75%, 21%, and 4%, respectively. The mean change score in functional AKSS for patients with high comorbidity was -6 points (95% confidence interval [CI] -7 to -5) compared with low comorbidity. The mean change score in clinical AKSS for patients with high comorbidity was -1 point (CI -2 to 0) compared with low comorbidity. Patients with knee OA and medium or high comorbidity can expect similar improvements in functional and clinical AKSS after TKA to patients with low comorbidity.

The Impact of Virtual Reality Training Combined with Traditional Chinese Medicine Health Preservation Therapy on Cognitive Function, Neurological Function, and Physical Function of Stroke Patients.

The aim of this study was to investigate the effects of virtual reality training combined with traditional Chinese medicine health preservation therapy on cognitive function, neurological function, and physical function of stroke patients. The patients were randomly divided into an experimental group (receiving virtual reality training combined with traditional Chinese medicine health preservation therapy) and a control group (receiving conventional rehabilitation treatment combined with traditional Chinese medicine health preservation therapy). A series of cognitive, neurological, and physical function assessments were conducted to collect and analyze data from both groups before treatment, after treatment, and during follow-up. The application of traditional Chinese medicine health preservation concepts was also explored. After treatment, the experimental group had significantly higher scores in the Mini-Mental State Examination (MMSE) compared to the control group. The overall effective rate of neurological function in the experimental group was higher than that in the control group. The Fugl-Meyer Assessment (FMA) scores for upper limb function in the experimental group were significantly higher than those in the control group. The degree of improvement in the Modified Barthel Index scores after treatment was significantly better in the experimental group compared to the control group (all P < 0.05). The results of this study demonstrate that virtual reality training combined with traditional Chinese medicine health preservation therapy significantly improves cognitive function, neurological function, and physical function in stroke patients. This approach provides new insights and methods for stroke rehabilitation therapy and is worthy of promotion.

The influence of mindfulness meditation combined with progressive muscle relaxation training on the clinical efficacy and quality of life of patients with sarcopenia receiving haemodialysis: a randomised controlled trial

ObjectiveTo study the effect of mindfulness meditation combined with progressive muscle relaxation training on the clinical efficacy and quality of life in patients with sarcopenia receiving maintenance haemodialysis (MHD).MethodsEligible patients with sarcopenia in our hospital were randomly assigned to a control group (n = 24) and an intervention group (n = 25). The control group received conventional dialysis treatment, while the intervention group underwent mindfulness meditation combined with progressive muscle relaxation training during the interdialysis period in addition to conventional dialysis treatment. The effect of the intervention was evaluated after 12 weeks.ResultsThere were no significant differences in the baseline values of various parameters between the two groups. Exercise capacity (sit-to-stand test,handgrip,time to 10 sit-ups) significantly improved in the intervention group after 12 weeks (32.68 ± 8.32 vs 26.50 ± 6.83; 37.42 ± 10.12 vs 28.12 ± 8.51; 19.8 ± 5.40 vs 25.29 ± 7.18) (p < 0.05). In terms of the kidney disease quality of life (KDQOLTM) score, all other dimensions except sexual function, social functioning, burden of kidney disease and work status dimensions showed significant improvement compared to the baseline (p < 0.05). In the control group, only the dialysis staff encouragement (DSE) and patient satisfaction (PS) dimensions showed slight improvements compared to the baseline (p > 0.05). When compared with the control group, the intervention group showed significant improvements in 10 dimensions of exercise capacity and KDQOLTM scores for physical function, role-physical, general health, energy, symptom/problem list, sleep, DSE, pain, cognitive function, emotional well-being and patient PS after 12 weeks (61.30 ± 5.38 vs 42.98 ± 5.73; 57.50 ± 3.55 vs 50.70 ± 3.62) (p < 0.05). Some inflammatory markers, such as the levels of interleukin-6 and high-sensitivity C-reactive protein (30.29 ± 2.96 vs 17.65 ± 3.22; 8.93 ± 0.99 vs 3.02 ± 0.34), showed a decrease during the intervention, while albumin and prealbumin levels were significantly increased compared with the baseline (30.62 ± 1.65 vs 35.60 ± 1.68; 0.32 ± 0.05 vs 0.44 ± 0.07) (p < 0.05).ConclusionCombined intervention training can improve the motor ability and quality of life of patients with sarcopenia within a short period of time.

Influence of continuous 4C nursing on quality of life and self-care ability of patients with diabetes retinopathy: An observational study.

This study aims to investigate the impact of continuous 4C nursing on patients with diabetes retinopathy (DR) and its influence on self-care ability. A total of 100 DR patients admitted to our hospital from October 2020 to October 2022 were randomly divided into a control group and an observation group, with 50 cases in each group. The control group received routine care, while the observation group received continuous 4C care. The nursing effects of both groups were compared. After nursing, the observation group showed a lower self-rating anxiety scale score and a higher self-care ability scale score compared to the control group (P < .05). The SQQL-VI scores for all social activities were also higher in the observation group (P < .05). Additionally, the observation group had lower levels of fasting blood glucose, 2-hour postprandial blood glucose, and glycated hemoglobin than the control group (P < .05). Moreover, the observation group had higher visual acuity and lower intraocular pressure than the control group (P < .05). The visual impairment rate was lower and the overall compliance rate was higher in the observation group compared to the control group (P < .05). After nursing, both groups showed improvements in symptoms, visual function, physical function, psychological and social activity scores, visual acuity, and patient satisfaction scores. The observation group showed greater improvements compared to the control group (P < .05). The application of continuous 4C nursing in DR patients has shown positive effects, including improved patient compliance and satisfaction, enhanced patient quality of life and visual acuity. These findings suggest that continuous 4C nursing should be widely promoted and applied in clinical practice.

Comparison of 2 different fixation techniques of comminuted acetabular quadrilateral surface fractures using square bracket-shaped tubular plate or interfragmentary screws in addition to supra/infrapectineal plate fixation: An observational study.

The management of comminuted quadrilateral fractures remains challenging, and treatment options are constantly evolving. The purpose of the present study was to examine the outcomes of 2 different fixation techniques in the management of comminuted quadrilateral fractures. Twenty-two patients with comminuted quadrilateral acetabular fractures were surgically treated with interfragmentary lag screw (group 1) and square bracket-shaped tubular (SBST) plate technique (group 2), in addition to suprapectineal and infrapectineal pelvic reconstruction plate fixation between January 2016 and July 2019 at our clinic. 2 years follow-up control data of each group were compared in terms of radiological and functional results, and complications. According to the functional score comparison, the mean Merle d'Aubigne Postel scoring system (MAP) score was 15.2/15.6 (P = .632), and the mean Harris hip scoring (HHS) system score was 74.65/77.3 (P = .664) in groups 1 and 2, respectively. Radiological comparison was performed according to matta radiological criteria (MRC), and 2 excellent, 6 good, 2 poor, 4 excellent, 4 good, and 4 poor radiological results were observed in groups 1 and 2, respectively. intraarticular screw penetration was detected in 3 patients in group 1, while there was no articular implant penetration in group 2 (P = .001). We believe that satisfactory results can be obtained with the SBST plate technique, offering functional and clinical outcomes that are similar to those of the interfragmentary screw technique. The SBST plate technique is superior in terms of avoiding intraarticular screw penetration and related revision surgery.

Exome functional risk score and brain connectivity can predict social adaptability outcome of children with autism spectrum disorder in 4 years' follow up.

Autism Spectrum Disorder (ASD) is a common neurodevelopmental disorder emerging in early childhood, with heterogeneous clinical outcomes across individuals. This study aims to recognize neuroimaging genetic factors associated with outcomes of ASD after a 4-year follow-up. A total of 104 ASD children were included in this study; they underwent clinical assessments, MRI data acquisition, and the whole exome sequencing (WES). Exome functional risk score (EFRS) was calculated based on WES; and two modalities of brain connectivity were constructed based on MRI data, that is functional connectivity (FC) for functional MRI (fMRI), and individual differential structural covariance network (IDSCN) for structural MRI (sMRI), to explore the neuroimaging genetic biomarker of outcomes of ASD children. Regression analysis found EFRS predicts social adaptability at the 4-year follow-up (Y = -0.013X + 9.29, p = 0.003). We identified 19 pairs of FC associated with autism symptoms severity at follow-up, 10 pairs of FC and 4 pairs of IDSCN associated with social adaptability at follow-up, and 10 pairs of FC associated with ASD EFRS by support vector regression (SVR). Related brain regions with prognostic predictive effects are mainly distributed in superior frontal gyrus, occipital cortex, temporal cortex, parietal cortex, paracentral lobule, pallidum, and amygdala for FC, and temporal cortex, thalamus, and hippocampus for IDSCN. Mediation model showed that ASD EFRS affects the social communication of ASD children through the mediation of FC between left middle occipital gyrus and left pallidum (RMSEA=0.126, CMIN=80.66, DF=42, p< 0.001, CFI=0.867, AIC=152). Our findings underscore that both EFRS and brain connectivity can predict social adaptability, and that brain connectivity serving as mediator in the relationship of EFRS and behaviors of ASD, suggesting the intervention targets in the future clinical application.

Examination of Pain, Quality of Life, Disability, and Anxiety in Patients Undergoing Lumbar Disc Surgery with and without COVID-19

Aim: This study aims to examine pain, disability, anxiety, and quality of life in patients undergoing lumbar disc herniation (LDH) surgery with and without COVID-19. Material and Method: Eighty patients who were diagnosed with LDH and planned surgery between March and September 2023 were included in the study. 50% of the patients were diagnosed with COVID-19 for at most six months, according to the positive polymerase chain reaction (PCR) test. 50% of the patients had no symptoms of COVID-19, ranging from mild to severe, and the PCR test was negative (-). The patients' pain level, disability, anxiety, and quality of life were evaluated and compared between the groups with and without COVID. Results: The mean scores of physical roles, physical function, mental health, body pain, and social function on the SF-36 quality of life scale in the LDH+COVID-19 (+) patient group were significantly lower than those in LDH+COVID-19 (-) (p

Nonlinear modeling of oral glucose tolerance test response to evaluate associations with aging outcomes.

As people age, their ability to maintain homeostasis in response to stressors diminishes. Physical frailty, a syndrome characterized by loss of resilience to stressors, is thought to emerge due to dysregulation of and breakdowns in communication among key physiological systems. Dynamical systems modeling of these physiological systems aims to model the underlying processes that govern response to stressors. We hypothesize that dynamical systems model summaries are predictive of age-related declines in health and function. In this study, we analyze data obtained during 75-gram oral-glucose tolerance tests (OGTT) on 1,120 adults older than 50 years of age from the Baltimore Longitudinal Study on Aging. We adopt a two-stage modeling approach. First, we fit OGTT curves with the Ackerman model-a nonlinear, parametric model of the glucose-insulin system-and with functional principal components analysis. We then fit linear and Cox proportional hazards models to evaluate whether usual gait speed and survival are associated with the stage-one model summaries. We also develop recommendations for identifying inadequately-fitting nonlinear model fits in a cohort setting with numerous heterogeneous response curves. These recommendations include: (1) defining a constrained parameter space that ensures biologically plausible model fits, (2) evaluating the relative discrepancy between predicted and observed responses of biological interest, and (3) identifying model fits that have notably poor model fit summary measures, such as [Formula: see text], relative to other fits in the cohort. The Ackerman model was unable to adequately fit 36% of the OGTT curves. The stage-two regression analyses found no associations between Ackerman model summaries and usual gait speed, nor with survival. The second functional principal component score was associated with faster gait speed (p<0.01) and improved survival (p<0.01).

Surgical treatment outcomes of acetabular posterior wall and posterior column fractures using 3D printing technology and individualized custom-made metal plates: a retrospective study

BackgroundFractures involving the posterior acetabulum with its rich vascular and neural supply present challenges in trauma orthopedics. This study evaluates the effectiveness of 3D printing technology with the use of custom-made metal plates in the treatment of posterior wall and column acetabular fractures.MethodsA retrospective analysis included 31 patients undergoing surgical fixation for posterior wall and column fractures of the acetabulum (16 in the 3D printing group, utilizing 3D printing for a 1:1 pelvic model and custom-made plates based on preoperative simulation; 15 in the traditional group, using conventional methods). Surgical and instrument operation times, intraoperative fluoroscopy frequency, intraoperative blood loss, fracture reduction quality, fracture healing time, preoperative and 12-month postoperative pain scores (Numeric Rating Scale, NRS), hip joint function at 6 and 12 months (Harris scores), and complications were compared.ResultsThe surgical and instrument operation times were significantly shorter in the 3D printing group (p < 0.001). The 3D printing group exhibited significantly lower intraoperative fluoroscopy frequency and blood loss (p = 0.001 and p < 0.001, respectively). No significant differences were observed between the two groups in terms of fracture reduction quality, fracture healing time, preoperative pain scores (NRS scores), and 6-month hip joint function (Harris scores) (p > 0.05). However, at 12 months, hip joint function and pain scores were significantly better in the 3D printing group (p < 0.05). Although the incidence of complications was lower in the 3D printing group (18.8% vs. 33.3%), the difference did not reach statistical significance (p = 0.433).ConclusionCombining 3D printing with individualized custom-made metal plates for acetabular posterior wall and column fractures reduces surgery and instrument time, minimizes intraoperative procedures and blood loss, enhancing long-term hip joint function recovery.Clinical Trial Registration12/04/2023;Trial Registration No. ChiCTR2300070438; http://www.chictr.org.cn.

Diagnosis and Management of Periprosthetic Joint Infections After Total Ankle Arthroplasty.

Periprosthetic joint infection (PJI) after total ankle arthroplasty (TAA) is a dreaded complication that may lead to catastrophic outcomes. Risk factors include a history of surgery on the operated ankle, low preoperative function scores, diabetes, extended surgical time, and postoperative wound-healing problems. Clinical presentation varies and may include increasing ankle pain and swelling, high temperature, local erythema, wound drainage, and dehiscence. The initial diagnostic evaluation should include plain radiographs, erythrocyte sedimentation rate, C-reactive protein levels, and leukocyte count. In suspected cases with elevated erythrocyte sedimentation rate and C-reactive protein, aspiration of the ankle joint for synovial fluid analysis, Gram staining, and culture should be performed. Antibiotic therapy should be based on the pathogen identified, and the surgical strategy should be determined based on the time lines of PJI. Early PJI can be treated with irrigation and débridement with polyethylene exchange. The surgical treatment of choice for late PJI is two-stage revision arthroplasty, which includes removal of the implant, insertion of an antibiotic spacer, and reimplantation of a TAA. In certain chronic PJI cases, permanent articulating antibiotic spacers can be left in place or an ankle arthrodesis can be performed. Below-knee amputation is considered as the final option after limb-sparing procedures have failed.

Effects of extracellular vesicles for ischemic stroke: A meta‑analysis of preclinical studies.

Ischemic stroke is a common occurrence worldwide, posing a severe threat to human health and leading to negative financial impacts. Currently available treatments still have numerous limitations. As research progresses, extracellular vesicles are being found to have therapeutic potential in ischemic stroke. In the present study, the literature on extracellular vesicle therapy in animal studies of ischemic stroke was screened by searching databases, including PubMed, Embase, Medline, Web of Science and the Cochrane Library. The main outcomes of the present study were the neurological function score, apoptotic rate and infarct volumes. The secondary outcomes were pro-inflammatory factors, including tumor necrosis factor-α (TNF-α), interleukin (IL)-1β and IL-6. The study quality was assessed using the CAMARADES Checklist. Subgroup analyses were performed to evaluate factors influencing extracellular vesicle therapy. Review Man3ager5.3 was used for data analysis. A total of 20 relevant articles were included in the present meta-analysis. The comprehensive analysis revealed that extracellular vesicles exerted a significant beneficial effect on neurobehavioral function, reducing the infarct volume and decreasing the apoptotic rate. Moreover, extracellular vesicles were found to promote nerve recovery by inhibiting pro-inflammatory factors (TNF-α, IL-1β and IL-6). On the whole, the present meta-analysis examined the combined effects of extracellular vesicles on nerve function, infarct volume, apoptosis and inflammation, which provides a foundation for the clinical study of extracellular vesicles.

Periosteal wrapping of the hamstring tendon autograft improves graft healing and prevents tunnel widening after anterior cruciate ligament anatomic reconstruction.

The periosteum is a readily available tissue at the hamstring harvest site that could be utilized to enhance graft healing and prevent tunnel widening without additional cost or morbidity. This study aimed to compare graft healing using magnetic resonance imaging (MRI) and functional clinical outcome scores in a matched cohort of patients who underwent anterior cruciate ligament (ACL) reconstruction with hamstring autografts with or without periosteal augmentation. Forty-eight patients who underwent ACL reconstruction (ACLR) were prospectively enrolled: 25 with standard ACLR (ST-ACLR) and 23 with periosteal augmented grafts (PA-ACLR). The same surgical techniques, fixation methods, and postoperative protocol were used in both groups. Signal-to-noise quotient (SNQ), graft healing at the bone-graft interface, graft signal according to the Howell scale, and femoral tunnel widening were evaluated using MRI after 1 year of follow-up. International knee documentation score (IKDC), Lysholm, Tegner activity scale, and visual analog scale for pain were used for functional evaluation at a minimum of 2years postoperative. The mean SNQ of the proximal part of the graft was 9.6 ± 9.2 and 2.9 ± 3.3 for the ST-ACLR and PA-ACLR groups, respectively (P = 0.005). The mean femoral tunnel widening was 30.3% ± 18.3 and 2.3% ± 9.9 for the ST-ACLR, PA-ACLR groups, respectively (P < 0.001). Complete graft tunnel healing was observed in 65% and 28% of cases in the PA-ACLR and ST-ACLR groups, respectively. Both groups showed marked improvements in functional scores, with no statistically significant differences. Periosteal wrapping of hamstring tendon autografts is associated with better graft healing and maturation and lower incidence of femoral tunnel widening based on MRI analysis 1year after ACL reconstruction. However, patient-reported outcomes and measured laxity were similar between the two groups at 2years follow up.

Quality of life and sleep, depression, family functioning, and marital adjustment in patients on hemodialysis and peritoneal dialysis.

End-stage renal disease is different from other chronic diseases that the treatment method is as difficult. Our aim in this study was to compare marital adjustment, sexual functions and family functioning between hemodialysis (HD) and peritoneal dialysis (PD) patient. A total of 21 HD and 27 PD patients were included. Beck Depression Inventory (BDI), Short Form-36 (SF-36), Pittsburgh Sleep Quality Index (PSQI), Arizona Sexual Experiences Scale (ASEX), Golombok-Rust Inventory for Sexual Satisfaction (GRISS), Marital Adjustment Test (MAT) and Family Assessment Device (FAD) were applied. BDI scores were significantly higher in HD patients (p < 0.001). According to FAD problem solving (p < 0.001), communication (p = 0.00) and general functioning scores (p = 0.04) were higher in PD. The rate of poor sleep quality was 44.4% in the PD group, and 66.7% in HD group (p = 0.12). General health (p = 0.04), vitality (p < 0.001), mental health (p = 0.00) and social functioning (p = 0.00) scores were lower in HD patients. HD patients are at high risk for psychiatric disorders due to the treatment modality. These patients should be monitored carefully and consultation-liaison services should be increased.

Identification of necroptosis-related gene signatures for predicting the prognosis of ovarian cancer

Ovarian cancer (OC) is one of the most prevalent and fatal malignant tumors of the female reproductive system. Our research aimed to develop a prognostic model to assist inclinical treatment decision-making.Utilizing data from The Cancer Genome Atlas (TCGA) and copy number variation (CNV) data from the University of California Santa Cruz (UCSC) database, we conducted analyses of differentially expressed genes (DEGs), gene function, and tumor microenvironment (TME) scores in various clusters of OC samples.Next, we classified participants into low-risk and high-risk groups based on the median risk score, thereby dividing both the training group and the entire group accordingly. Overall survival (OS) was significantly reduced in the high-risk group, and two independent prognostic factors were identified: age and risk score. Additionally, three genes—C-X-C Motif Chemokine Ligand 10 (CXCL10), RELB, and Caspase-3 (CASP3)—emerged as potential candidates for an independent prognostic signature with acceptable prognostic value. In Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses, pathways related to immune responses and inflammatory cell chemotaxis were identified. Cellular experiments further validated the reliability and precision of our findings. In conclusion, necroptosis-related genes play critical roles in tumor immunity, and our model introduces a novel strategy for predicting the prognosis of OC patients.

Long non-coding RNA TUG1 is down-regulated in Friedreich’s ataxia

Abstract Friedreich's Ataxia (FRDA) is a neurodegenerative disorder caused by reduced frataxin (FXN) levels. It leads to motor and sensory impairments and has a median life expectancy of around 35 years. As the most common inherited form of ataxia, FRDA lacks reliable, non-invasive biomarkers, prolonging and inflating the cost of clinical trials. This study proposes TUG1, a long non-coding RNA, as a promising blood-based biomarker for FRDA, which is known to regulate various cellular processes. In a previous study using a frataxin knockdown mouse model, we observed several hallmark FRDA symptoms. Building on this, we hypothesized that a dual-source approach—comparing the data from peripheral blood samples from FRDA patients with tissue samples from affected areas in FRDA knockdown mice, tissues usually unattainable from patients—would effectively identify robust biomarkers. A comprehensive reanalysis was conducted on gene expression data from 183 age- and sex-matched peripheral blood samples of FRDA patients, carriers, and controls, and 192 tissue datasets from FRDA knockdown mice. Blood and tissue samples underwent RNA isolation and quantitative reverse transcription PCR, and frataxin knockdown was confirmed through ELISA. Tug1 RNA interaction was explored via RNA pull-down assays. Validation was performed in serum samples on an independent set of 45 controls and 45 FRDA patients, and in blood samples from 66 heterozygous carriers and 72 FRDA patients. Tug1 and Slc40a1 emerged as potential blood-based biomarkers, confirmed in the FRDA knockdown mouse model (One-way ANOVA, p ≤ 0.05). Tug1 was consistently downregulated after Fxn knockdown and correlated strongly with Fxn levels (R2 = 0.71 during depletion, R2 = 0.74 during rescue). Slc40a1 showed a similar but tissue-specific pattern. Further validation of Tug1's downstream targets strengthened its biomarker candidacy. In additional human samples, TUG1 levels were significantly downregulated in both whole blood and serum of FRDA patients compared to controls (Wilcoxon signed-rank test, p &amp;lt; 0.05). Regression analyses revealed a negative correlation between TUG1 fold-change and disease onset (p &amp;lt; 0.0037), and positive correlations with disease duration and Functional Disability Stage score (p &amp;lt; 0.04). This suggests that elevated TUG1 levels correlate with earlier onset and more severe cases. This study identifies TUG1 as a potential blood-based biomarker for FRDA, showing consistent expression variance in human and mouse tissues related to disease severity and key FRDA pathways. It correlates with frataxin levels, indicating its promise as an early, non-invasive marker. TUG1 holds potential for FRDA monitoring and therapeutic development, meriting additional research.
