Elucidating sleep disorders: a comprehensive bioinformatics analysis of functional gene sets and hub genes.

Sleep disorders (SD) are known to have a profound impact on human health and quality of life although their exact pathogenic mechanisms remain poorly understood. The study first accessed SD datasets from the GEO and identified DEGs. These DEGs were then subjected to gene set enrichment analysis. Several advanced techniques, including the RF, SVM-RFE, PPI networks, and LASSO methodologies, were utilized to identify hub genes closely associated with SD. Additionally, the ssGSEA approach was employed to analyze immune cell infiltration and functional gene set scores in SD. DEGs were also scrutinized in relation to miRNA, and the DGIdb database was used to explore potential pharmacological treatments for SD. Furthermore, in an SD murine model, the expression levels of these hub genes were confirmed through RT-qPCR and Western Blot analyses. The findings of the study indicate that DEGs are significantly enriched in functions and pathways related to immune cell activity, stress response, and neural system regulation. The analysis of immunoinfiltration demonstrated a marked elevation in the levels of Activated CD4+ T cells and CD8+ T cells in the SD cohort, accompanied by a notable rise in Central memory CD4 T cells, Central memory CD8 T cells, and Natural killer T cells. Using machine learning algorithms, the study also identified hub genes closely associated with SD, including IPO9, RAP2A, DDX17, MBNL2, PIK3AP1, and ZNF385A. Based on these genes, an SD diagnostic model was constructed and its efficacy validated across multiple datasets. In the SD murine model, the mRNA and protein expressions of these 6 hub genes were found to be consistent with the results of the bioinformatics analysis. In conclusion, this study identified 6 genes closely linked to SD, which may play pivotal roles in neural system development, the immune microenvironment, and inflammatory responses. Additionally, the key gene-based SD diagnostic model constructed in this study, validated on multiple datasets showed a high degree of reliability and accuracy, predicting its wide potential for clinical applications. However, limited by the range of data sources and sample size, this may affect the generalizability of the results.

A Randomized Controlled Trial of Topical Analgesia Post-Hemorrhoidectomy (TAPH Trial).

Postoperative pain remains the greatest problem after hemorrhoidectomy. Pain is hypothesized to arise from bacterial infection, sphincter spasm, and local inflammation. A randomized controlled factorial trial was conducted to assess the effects of metronidazole, diltiazem, and lidocaine on post-hemorrhoidectomy pain. A double blinded randomized controlled factorial trial. A multicenter trial was conducted in Auckland, New Zealand. 192 Participants were randomized (1:1:1:1) into four parallel arms. Participants were randomized into one of four groups receiving topical treatment with 10% metronidazole (M), 10% metronidazole + 2% diltiazem (MD), 10% metronidazole + 4% lidocaine (ML), or 10% metronidazole + 2% diltiazem + 4% lidocaine (MDL). Participants were instructed to apply to the anal verge 3 times daily for 7 days. The primary outcome was pain on the visual analogue scale on day 4. The secondary outcomes included analgesia usage, pain on bowel motion, and functional recovery index. There was no significant difference in the pain and recovery scores when diltiazem or lidocaine was added to metronidazole (score difference between presence and absence of D in the formulation: -3.69, 95% CI: -13.3, 5.94, p = 0.46; between presence and absence of L: -5.67, 95% CI: -15.5, 3.80, p = 0.24). The combination of MDL did not further reduce pain. Secondary analysis revealed a significant difference between the best (ML) and worst (MDL) groups in both pain and functional recovery scores. There were no significant differences in analgesic usage, complications, or return to work between the groups. No clinically important adverse events were reported. The adverse event rate did not change in the intervention groups. Topical metronidazole was utilized in the control group, rather than a pure placebo. There was no significant difference in pain when topical diltiazem or lidocaine, or both, was added to topical metronidazole. NCT04276298.

Metabolic acidosis and sexual dysfunction in chronic kidney disease in predialysis group: Cross-sectional study from a single center.

This study aimed to investigate the prevalence of sexual disorders in stage 2 - 5 chronic kidney disease (CKD) during predialysis and its relationship with laboratory parameters. This cross-sectional study included 110 predialysis patients and 110 healthy controls admitted to clinics. The International Index of Erectile Function (IIEF) and Female Sexual Function Index (FSFI) were used. Sexual dysfunction was detected in 76% of female patients and 31.4% of the control group, and the FSFI total and subscale scores of the patients were significantly lower than those of the control group. The frequency of erectile dysfunction in male patients and controls was 56.7% and 33.3%, respectively. The erectile function, sexual satisfaction, and overall satisfaction scores on the IIEF scale were significantly lower than those in the control group. Low glomerular filtration rate, high calcium levels, increased C-reactive protein, anemia, and metabolic acidosis in male and female patients, and testosterone deficiency in male patients were associated with sexual dysfunction. In multiple regression analysis, eGFR was the only independent variable associated with sexual dysfunction. Luteinizing hormone (LH) and prolactin levels increased as the disease progressed in men and women with sexual dysfunction, while testosterone levels decreased in male patients. Low testosterone levels were related to erectile dysfunction. The increase in parathormone and prolactin levels was related to loss of libido in the male and female patient groups. Metabolic acidosis and low eGFR appear to be the most important risk factors contributing to sexual disorders in patients with CKD.

Resection arthroplasty versus dual mobility prosthesis in the treatment of trapeziometacarpal joint osteoarthritis: A 3 year non-randomized prospective study

PurposeResection arthroplasty (RA) is still the most common surgical intervention for the treatment of symptomatic trapeziometacarpal (TMC) joint osteoarthritis. The implantation of a dual mobility prosthesis may represent a joint function preserving alternative. The aim of the presented study is to prospectively compare the outcomes of RA with dual mobility prosthesis. MethodsIn this 2-center non-randomized prospective study, we compared results of RA (n = 22) with implantation of a dual mobility prosthesis (n = 49) (Touch®) at a minimum of 3-year follow-up. The patients underwent preoperative assessments and postoperative follow-up at 6 weeks, 3, 6, 12, 24, and 36 months. Comparisons were conducted, covering pain assessment via the visual analogue scale (VAS), thumb range of motion (ROM), pinch and grip strength, as well as functional scores and radiological examinations. ResultsThe time intervals from surgery until absence of pain on the VAS (3 months: 3 vs 1, p = 0.0001), recovery of ROM in radial (3 months: 33° vs 42°, p = 0.0001), and palmar abduction (3 months: 33° vs 48°, p = 0.0001), were significantly longer for the RA group compared with the prosthesis group. At 3-year follow-up there was no significant difference in absence of pain, ROM and grip strength between both groups. Key pinch strength was significantly weaker in the RA group compared to prosthesis group at 3 months (2.6 kg vs 4.6 kg, p = 0.001), to 3-year follow-up (3.1 kg vs 5.7 kg, p = 0.0001). The final mean DASH (15.5 vs 13.2, p = 0.01) and MHQ scores (78 vs 82, p = 0.01) were significantly better in the prosthesis group. ConclusionBoth techniques show high patient satisfaction in mid-term follow-up. Dual mobility TMC joint arthroplasty seems to be associated with a superior pinch strength and shorter time of recovery as compared to patients after RA.

THE TEN-YEAR PATIENT-REPORTED AND CLINICAL OUTCOMES OF A SERIES OF 156 MOBILE-BEARING TOTAL ANKLE ARTHROPLASTIES AND THE EFFECTS OF PATIENT AGE

BackgroundTotal Ankle Replacement (TAR) is an established treatment option for end-stage ankle arthritis. We analysed at minimum, 10-year patient-reported and clinical outcomes of 156 TARs from a single centre. We specifically compared outcomes between patients under 60 and over 60 at time of surgery.MethodsData was collected retrospectively from our departmental patient database. It included all patients who underwent a TAR by a single surgeon between 2006 and 2010 and patients were divided into those under 60 and those over 60 at the time of surgery. Patient reported outcomes (PROMs), including WOMAC, SF-36 and patient satisfaction scores and complications were analysed preoperatively and at one, two, five and over 10 years postoperatively.ResultsThere were 156 patients included in this analysis, 61 were under 60 (mean age 50.29) and 95 were over 60 (mean age 69.12). A total of 12 patients had revision surgery, (nine in the under 60 group) and 52 patients were deceased at the time of analysis (10 in the under 60 group). At one year the over 60 group had less pain and better functional scores (p=0.02, p=0.017). At two, five and ten years there was no statistical difference in pain and function between groups. At two years the over 60s reported less stiffness and quicker return to activities of daily living (p=0.007, p=0.001). However, at five and 10 years there was no statistical difference in any domain.ConclusionsThis study demonstrates that age does not correlate with a significant difference in pain or functional outcomes in patients who have TAR, at over 10 years follow up. The higher revision rates in the younger group may correlate with higher functional demand and lower mortality rate.

A COMPARISON OF FUNCTIONAL OUTCOME SCORES FOR PRIMARY AND REVISION ANKLE ARTHROPLASTIES

BackgroundPatients who undergo either primary or revision total ankle replacement (TAR) expect improvements in pain, function and quality of life. The goal of this study was to measure the functional outcome improvements and the difference in patient-reported outcomes in patients undergoing primary total ankle replacements compared to revision TAR.MethodsA single-center prospective cohort study was undertaken between 2016 and 2022. All patients were followed up for a minimum of 6 months. Patients undertook the Manchester Oxford Foot Questionnaire (MoxFQ) and EQ-5D health quality questionnaires pre-operatively, at 6 months and yearly for life. The Mann Whitney test was undertaken for statistical analysis.ResultsA total of 165 primary and 71 revision ankle replacements were performed between 2016 and 2022. The mean age was 71 years for primary replacements and 69 years for revisions. The INFINITY was utilized in the majority of primary total ankle replacements. Revision replacements were either the INBONE II or INVISION and they were most often revising the MOBILITY implant. The main indication for revision was aseptic loosening (83%). Other causes included infection, malalignment and insert wear. The overall MoxFQ improved by a mean of 46.5 for primaries and 40.2 for revisions. The EQ-5D score also showed overall improvements with the mean difference in mobility increasing by 1.6.ConclusionBoth primary and revision ankle replacements result in improved functional scores at 6 months, 1 year and 2 years. In this cohort with the implants used, both primary and revision ankle replacements demonstrate similar improvements in functional scores.

Comparison of the Efficacy of Different Combined Therapies Based on Modified Core Decompression for the Treatment of Early-stage Nontraumatic Osteonecrosis of the Femoral Head: A Retrospective Clinical Study.

Osteonecrosis of the femoral head (ONFH) is a severe orthopedic disease, which may cause severe hip dysfunction in later stage. Therefore, it is necessary to treat nontraumatic ONFH during the early stages. The aim of this study was to evaluate the clinical efficacy and survival rates of different combined therapies based on modified core decompression (CD) for early-stage nontraumatic ONFH. This retrospective cohort study assessed 397 hips with ONFH who underwent different combined therapies based on modified CD in our institution between January 2010 and December 2017. Patients were classified into six groups based on treatment modalities, and were followed up at 1 year and 5 years postoperatively. Clinical outcomes, including Harris hip score (HHS) and Western Ontario and McMaster Universities osteoarthritis index (WOMAC), were compared to evaluate the hip function and quick rehabilitation effect. Radiographic progression of ONFH and the incidence of total hip arthroplasty were analyzed to evaluate the survival rate of ONFH postoperatively. Statistical analyses were mainly performed with Kruskal-Wallis test, chi-square test and Kaplan-Meier method. HHS increased significantly in all groups but showed no significant differences among the six groups in the first years. The nonvascularized allogeneic fibula with bone grafting (NVAF + BG) and percutaneous femoral neck-head fenestration with bone grafting via the direct anterior approach (DAA + BG) groups had significantly higher HHS (p = 0.010; p = 0.025) and WOMAC function score (p < 0.001; p = 0.012) than the CD group 5 years postoperatively. Compared with the CD group, all the other groups showed statistically significant differences in radiographic progression (p < 0.001) and a higher survival rate with no significant difference (p = 0.569). Our study demonstrates the potential use of NVAF + BG and DAA + BG, may serve as a promising combined therapy for the treatment of early-stage nontraumatic ONFH.

Upper extremity vascular injuries: Etiology, management and outcome

BACKGROUND Vascular injuries of the upper extremities are considered relatively rare injuries affecting mostly the young population. They often are complex injuries accompanied by other musculoskeletal trauma or trauma in other anatomic locations. Their management is challenging since they can lead to disabilities with major socioeconomic effects. AIM To analyze data about the mechanism of injury, the management algorithm and functional outcomes of vascular injuries of the upper extremity. METHODS One hundred and fifteen patients (96 males and 19 females) with arterial injuries of the upper extremity treated in a tertiary trauma center from January 2003 to December 2022 was conducted. Mean patients’ age was 33.7 years and the mean follow up time was 7.4 years. Patients with Mangled Extremity Severity Score ≥ 7 and Injury Severity Score ≥ 20, previous upper limb surgery or major trauma and any neuromuscular or psychiatric disease were excluded, from the study. RESULTS A penetrating trauma was the most common cause of injury. The radial artery was the artery injured in most of the cases (37.4%) followed by the ulnar (29.5%), the brachial (12.1%) and the axillary (6%). A simultaneous injury of both of the forearm’s arteries was in 15.6% of the cases. In 93% of the cases there were other concomitant musculoskeletal injuries of the extremity. Tendon lacerations were the most common, followed by nerve injuries. The postoperative functional scores (full Disabilities of the Arm, Shoulder, and Hand and VAS) had very satisfactory values. CONCLUSION Although vascular injuries of the upper extremity are rare, they may occur in the context of major combined musculoskeletal trauma. Although a multidisciplinary approach is essential to optimize outcome, the ability of trained hand surgeons to repair all injuries in combined vascular and musculoskeletal upper extremity trauma, excluding isolated vascular injuries, ensures shorter operative times and better functional outcomes.

The association between HIV infection, disability and lifestyle activity among middle-aged and older adults: an analytical cross-sectional study in Ivory Coast (the VIRAGE study)

IntroductionPeople living with HIV (PLWH) live longer and face new health challenges resulting from the confluence of chronic HIV infection and the natural effect of aging and comorbidities. However, there is a dearth of information on the long-term impact of HIV infection on the health and wellbeing of PLWH in sub-Saharan Africa. This research aimed to fill this gap by reporting on physical, functional and social outcomes among PLWH treated at a referral center in Abidjan, Ivory Coast, and comparing them with those of a control group.MethodsBody composition, functional capacity, sarcopenia, limitations in daily activities and social participation were assessed among 300 PLWH (aged ≥ 30 years) and 200 uninfected adults of similar age and sex. The associations between these outcomes and participants’ socioeconomic characteristics, HIV history and physical activity level were assessed using generalized additive models adjusted for age and sex.ResultsThe median age was 51 years, and the median antiretroviral therapy duration was 15 years. Compared to controls, PLWH reported higher levels of physical activity (p < 0.0001). They had a lower muscle index (adjusted p < 0.0001) and grip strength (adjusted p < 0.0001) but achieved similar performance on the 6-min walk test (6MWT, p = 0.2). Among PLWH, physical activity level was positively associated with better performance in the 6MWT (p = 0.006) and greater hand grip strength (p = 0.04). The difference in physical performance according to the level of physical activity appeared mainly after the age of 60. PLWH reported similar rates of activity limitations (p = 0.8), lower depression levels and greater scores for social functioning (p = 0.02).ConclusionIn this study, PLWH achieved high levels of physical activity, which may explain why they maintained good physical performance and social functioning despite having a higher risk of sarcopenia. These results have important implications for resource-limited health systems and show avenues for chronic care models.Trial registrationThis study was registered on the ClinicalTrials.gov website (NCT05199831, first registration the 20/01/2022).

Functional independence measure, sequelae, and comorbidities in individuals with COVID-19: a cross-sectional study

Objective: to verify whether there is loss of functionality and association between sequelae, comorbidities and between the Functional Independence Measure with sociodemographic data and clinical aspects in individuals affected by COVID-19. Method: this is a cross-sectional, descriptive, exploratory and quantitative study. Participants were contacted by telephone and answered a questionnaire covering sociodemographic and clinical aspects; post-COVID-19 sequelae, presence of comorbidities and Functional Independence Measure Scale. Results: 172 individuals participated with an average age of 41.42±14.21 years, 54.7% were female, 34.9% had comorbidities, 80.2% had post-COVID sequelae, 90.1% did not require hospitalization and 93.6% were vaccinated. The total Functional Independence Measure score was 120.73±11.3, corresponding to complete independence. There was an association between the cognitive domain and female sex (p=0.022) and white individuals (p=0.025), and between the motor domain, age between 18 and 59 years (p=0.014) and not being vaccinated against COVID-19 (p=0.046). Conclusion: comorbidities are associated with post-COVID-19 sequelae. Non-vaccinated individuals, when infected with COVID-19, may present impairment in the motor domain.

Factors associated with changes in the quality of life and family functioning scores of primary caregivers of children and young people with primary brain tumors in Karachi, Pakistan: a prospective cohort study

BackgroundThere are limited data available, particularly in low- and middle-income countries (LMICs), on the long-term quality of life (QoL) and family functioning of primary caregivers of children and young people (CYPs) affected by primary brain tumors (PBTs). This study aimed to assess the factors associated with the mean change in QoL and family functioning scores of primary caregivers of CYP patients with PBTs 12 months posttreatment.MethodsThis prospective cohort study enrolled CYPs aged 5–21 years with newly diagnosed PBTs and their primary caregivers. The study was carried out between November 2020 and July 2023. The primary caregivers of CYPs were recruited from two major tertiary care centers in Karachi, Pakistan. The primary caregivers QoL were assessed by the Pediatric Quality of Life Inventory (PedsQL) Family Impact Module. The assessment was undertaken by a psychologist at the time of diagnosis and 12 months posttreatment. The data were analyzed with STATA version 12.ResultsForty-eight CYPs with newly diagnosed PBTs and their primary caregivers (46 mothers and 2 fathers) were enrolled. At 12 months posttreatment, 25 (52%) CYPs and their primary caregivers (mothers) were reassessed, and 23 (48%) were lost to follow-up. On multivariable analysis, a significant decrease in mothers’ mean 12-month posttreatment QoL and family functioning scores was associated with CYP having posttreatment seizures (beta= -10.2; 95% CI: -18.4 to -2.0) and with the financial burden associated with the CYP’s illness (beta= -0.3; 95% CI: -0.4 to -0.1). However, in those cases where CYP had higher posttreatment quality of life scores (beta = 0.4; 95% CI = 0.1, 0.6) and posttreatment higher verbal intelligence scores (beta = 0.1; 95% CI = 0.01, 0.3), the mothers’ QoL and family functioning scores were significantly greater.ConclusionWe found a significant decrease in QoL of mothers who had a high financial burden and whose CYP had posttreatment seizures. However, those whose CYPs had higher posttreatment verbal intelligence scores and quality of life scores had significantly greater QoL scores. Identification of the factors that influence primary caregivers QoL has the potential to aid in the development of targeted strategies to alleviate stressors and improve the overall quality of life for primary caregivers and their children who are at high risk.

Leukocyte filtration and leukocyte modulation therapy during extracorporeal cardiopulmonary resuscitation in a porcine model of prolonged cardiac arrest

Extracorporeal cardiopulmonary resuscitation (ECPR) is emerging as a feasible and effective rescue strategy for prolonged cardiac arrest (CA). However, prolonged total body ischemia and reperfusion can cause microvascular occlusion that prevents organ reperfusion and recovery of function. One hypothesized mechanism of microvascular “no-reflow” is leukocyte adhesion and formation of neutrophil extracellular traps. In this study we tested the hypothesis that a leukocyte filter (LF) or leukocyte modulation device (L-MOD) could reduce NETosis and improve recovery of heart and brain function in a swine model of prolonged cardiac arrest treated with ECPR. Thirty-six swine (45.5 ± 2.5 kg, evenly distributed sex) underwent 8 min of untreated ventricular fibrillation CA followed by 30 min of mechanical CPR with subsequent 8 h of ECPR. Two females were later excluded from analysis due to CPR complications. Swine were randomized to standard care (Control group), LF, or L-MOD at the onset of CPR. NET formation was quantified by serum dsDNA and citrullinated histone as well as immunofluorescence staining of the heart and brain for citrullinated histone in the microvasculature. Primary outcomes included recovery of cardiac function based on cardiac resuscitability score (CRS) and recovery of neurologic function based on the somatosensory evoked potential (SSEP) N20 cortical response. In this model of prolonged CA treated with ECPR we observed significant increases in serum biomarkers of NETosis and immunohistochemical evidence of microvascular NET formation in the heart and brain that were not reduced by LF or L-MOD therapy. Correspondingly, there were no significant differences in CRS and SSEP recovery between Control, LF, and L-MOD groups 8 h after ECPR onset (CRS = 3.1 ± 2.7, 3.7 ± 2.6, and 2.6 ± 2.6 respectively; p = 0.606; and SSEP = 27.9 ± 13.0%, 36.7 ± 10.5%, and 31.2 ± 9.8% respectively, p = 0.194). In this model of prolonged CA treated with ECPR, the use of LF or L-MOD therapy during ECPR did not reduce microvascular NETosis or improve recovery of myocardial or brain function. The causal relationship between microvascular NETosis, no-reflow, and recovery of organ function after prolonged cardiac arrest treated with ECPR requires further investigation.

Analysis of the Effect of Minimally Invasive Locking Plate Internal Fixation on Fracture Healing and Functional Recovery in Patients with Proximal Humerus Fractures

Objective: To investigate the effect of minimally invasive locking plate internal fixation on fracture healing and functional recovery in patients with proximal humerus fractures. Methods: 98 patients with proximal humerus fractures admitted to the hospital from August 2021 to July 2023 were selected and divided into the control group (n = 49) and the observation group (n = 49) according to the lottery method. The control group implemented conventional treatment, and the observation group implemented minimally invasive locking plate internal fixation. The treatment effect and complications, surgery-related indexes, and functional recovery of the shoulder joint in the two groups were compared. Results: Compared with the control group, the observation group (97.96%) had a better therapeutic effect than the control group (73.47%) (χ2 = 12.000, P &lt; 0.05); the complication rate of the observation group (2.04%) was lower than that of the control group (18.37%) (χ2 = 7.127, P &lt; 0.05); the fracture healing rate of the observation group (97.96%) was higher than that of the control group (81.63%) (χ2 = 7.127, P &lt; 0.05). The operation time of the observation group (74.25 ± 10.30 minutes) was shorter than that of the control group (115.63 ± 20.30 minutes) (t = 12.725, P &lt; 0.05), the intraoperative bleeding of the observation group (177.30 ± 19.63 ml) was less than that of the control group (306.63 ± 30.62 ml) (t = 24.890, P &lt; 0.05). The fracture healing time was shorter in the observation group (12.30 ± 2.30 weeks) than in the control group (16.23 ± 2.66 weeks) (t = 7.823, P &lt; 0.05), and the hospitalization time was shorter in the observation group (9.30 ± 0.99 days) than in the control group (12.66 ± 2.20 days) (t = 9.749, P &lt; 0.05). Compared with the control group, the pain, muscle strength, activity function, and activity score of the observation group were significantly different (t = 6.398, 12.817, 8.386, 7.892, P &lt; 0.05); compared with the control group, the observation group’s abduction, forward flexion, external rotation, internal rotation, and posterior rotation were significantly different (t = 3.042, 2.843, 3.633, 4.669, 9.176, P &lt; 0.05). Conclusion: Minimally invasive locking plate internal fixation for proximal humerus fracture can adjust its surgery-related indexes, increase the patients’ shoulder joint mobility, enhance the shoulder joint function, improve the fracture healing rate and therapeutic effect, and reduce the complications, which is worth recommending in clinical practice.

Comparative study of percutaneous endoscopic lumbar decompression and traditional revision surgery in the treatment of symptomatic adjacent segment degeneration

ObjectiveThe objective of this study is to evaluate and compare the surgical outcomes and complications of Percutaneous Endoscopic Lumbar Decompression (PELD) and traditional revision surgery in treating symptomatic Adjacent Segment Degeneration (ASD). This comparison aims to delineate the advantages and disadvantages of these methods, assisting spine surgeons in making informed surgical decisions.Methods66 patients with symptomatic ASD who failed conservative treatment for more than 1 month and received repeated lumbar surgery were retrospectively collected in the study from January 2015 to November 2018, with the average age of 65.86 ± 11.04 years old. According to the type of surgery they received, all the patients were divided in 2 groups, including 32 patients replaced the prior rod in Group A and 34 patients received PELD at the adjacent level in Group B. Patients were followed up routinely and received clinical and radiological evaluation at 3, 6, 12 months and yearly postoperatively. Complications and hospital costs were recorded through chart reviews.ResultsThe majority of patients experienced positive surgical outcomes. However, three cases encountered complications. Notably, Group B patients demonstrated superior pain relief and improved postoperative functional scores throughout the follow-up period, alongside reduced hospital costs (P < 0.05). Additionally, significant reductions in average operative time, blood loss, and hospital stay were observed in Group B (P < 0.05). Notwithstanding these benefits, three patients in Group B experienced disc re-herniation and underwent subsequent revision surgeries.ConclusionsWhile PELD offers several advantages over traditional revision surgery, such as reduced operative time, blood loss, and hospital stay, it also presents a higher likelihood of requiring subsequent revision surgeries. Future studies involving a larger cohort and extended follow-up periods are essential to fully assess the relative benefits and drawbacks of these surgical approaches for ASD.

Adhesive capsulitis: the importance of early diagnosis and treatment

Abstract Background Adhesive capsulitis (AC), more commonly known as "frozen shoulder”, is a painful shoulder condition. The illness progresses through three phases: freezing, frozen and thawing. A gold standard treatment for adhesive capsulitis is not defined. The goal of any treatment is to reduce pain and restore shoulder movement. Objective Objective of the present study is to evaluate the efficacy of gleno-humeral hydrodistension associated with physical therapy in patients with diagnosed adhesive capsulitis comparing the outcomes in term of pain and range of motion in patients with a phase 1 and a phase 2 disease. Method Between January 2022 and April 2023, We evaluated 87 patients with adhesive capsulitis, 47 were excluded for others concomitant pathologies, finally 40 patients were enrolled for the study, of whom 23 had capsulitis in stage 1 and 17 in stage 2. Patients were evaluated at baseline and at 2, 4 and 6 months after infiltration recording range of motion in all planes, pain and functionality scores. Results A significant improvement was recorded in shoulder range of motion in all planes with the except of extension in both groups. Phase 2 patients were able to regain shoulder range of motion in all planes except internal rotation which was recovered with more difficulty. Pain and functionality scores improved significantly between baseline and follow-up visits. Conclusion Ultrasound-assisted hydrodistention of the glenohumeral joint combined with targeted exercise has been successful in improving pain relief, reducing disability, and increasing range of motion in subjects with stage 1 and 2 adhesive capsulitis, especially if diagnosed before phase 2 (when the range of motion is completely reduced).

Identification of an inflammatory response-related gene prognostic signature and immune microenvironment for cervical cancer.

Background: Cervical cancer (CC) is the fourth most common cancer among women worldwide. As part of the brisk cross-talk between the host and the tumor, prognosis can be affected through inflammatory responses or the tumor microenvironment. However, further exploration of the inflammatory response-related genes that have prognostic value, microenvironment infiltration, and chemotherapeutic therapies in CC is needed. Methods: The clinical data and mRNA expression profiles of CC patients were downloaded from a public database for this study. In the TCGA cohort, a multigene prognostic signature was constructed by least absolute shrinkage and selection operator (LASSO) and Cox analyses. CC patients from the GEO cohort were used for validation. K‒M analysis was used to compare overall survival (OS) between the high- and low-risk groups. Univariate and multivariate Cox analyses were applied to determine the independent predictors of OS. The immune cell infiltration and immune-related functional score were calculated by single-sample gene set enrichment analysis (GSEA). Immunohistochemistry was utilized to validate the protein expression of prognostic genes in CC tissues. Results: A genetic signature model associated with the inflammatory response was built by LASSO Cox regression analysis. Patients in the high-risk group had a significantly lower OS rate. The predictive ability of the prognostic genes was evaluated by means of receiver operating characteristic (ROC) curve analysis. The risk score was confirmed to be an independent predictor of OS by univariate and multivariate Cox analyses. The immune status differed between the high-risk and low-risk groups, and the cancer-related pathways were enriched in the high-risk group according to functional analysis. The risk score was significantly related to tumor stage and immune infiltration type. The expression levels of five prognostic genes (LCK, GCH1, TNFRSF9, ITGA5, and SLC7A1) were positively related to sensitivity to antitumor drugs. Additionally, the expression of prognostic genes was significantly different between CC tissues and myoma patient cervix (non-tumorous) tissues in the separate sample cohort. Conclusion: A model consisting of 5 inflammation-related genes can be used to predict prognosis and influence immune status in CC patients. Furthermore, the inhibition or enhancement of these genes may become a novel alternative therapy.

Quality of life gains in frail and intermediate-fit patients with multiple Myeloma: Findings from the prospective HOVON123 clinical trial

BackgroundFrailty in newly-diagnosed multiple myeloma (NDMM) patients is associated with treatment-related toxicity, which negatively affects health-related quality of life (HRQoL). Currently, data on changes in HRQoL of frail and intermediate-fit MM patients during active treatment and post-treatment follow-up are absent. MethodsThe HOVON123 study (NTR4244) was a phase II trial in which NDMM patients ≥ 75 years were treated with nine dose-adjusted cycles of Melphalan-Prednisone-Bortezomib (MPV). Two HRQoL instruments (EORTC QLQ-C30 and -MY20) were obtained before start of treatment, after 3 and 9 months of treatment and 6 and 12 months after treatment for patients who did not yet start second-line treatment. HRQoL changes and/or differences in frail and intermediate-fit patients (IMWG frailty score) were reported only when both statistically significant (p < 0.005) and clinically relevant (>MID). Results137 frail and 71 intermediate-fit patients were included in the analysis. Compliance was high and comparable in both groups. At baseline, frail patients reported lower global health status, lower physical functioning scores and more fatigue and pain compared to intermediate-fit patients. Both groups improved in global health status and future perspective; polyneuropathy complaints worsened over time. Frail patients improved over time in physical functioning, fatigue and pain. Improvement in global health status occurred earlier than in intermediate-fit patients. ConclusionHRQoL improved during anti-myeloma treatment in both intermediate-fit and frail MM patients. In frail patients, improvement occurred faster and, in more domains, which was retained during follow-up. This implies that physicians should not withhold safe and effective therapies from frail patients in fear of HRQoL deterioration.

Prognostic factors of nonsurgical intervention outcomes for patients with frozen shoulder: a retrospective study

Purpose This study aimed to investigate the correlation between mental and physical health-related quality of life and the outcomes of conservative treatment in patients with frozen shoulder (FS). Methods This was a two-center retrospective study. It included 84 consecutive patients who underwent a 3-month treatment comprising education, physical therapy, and corticosteroid-anesthetic injections. Changes in range of motion (ROM) and Shoulder Pain and Disability Index (SPADI) scores, measured at baseline and after 3 months, were selected as dependent variables. Data on age, sex, Body Mass Index, duration of symptoms, dominant affected limb, and Short Form-36 (SF-36) subscales were gathered at baseline and investigated as prognostic factors. Backward stepwise regression models were used to identify significant associations. Results At 3-month follow-up, all the patients showed significant improvement. Higher SF-36 General Health, Mental Health and Social Functioning scores at baseline were associated with a greater beneficial change in ROM and SPADI. In contrast, lower SF-36 Bodily Pain and Role Emotional scores were found to be associated with greater improvement. Conclusion The study findings indicate that the self-perceived mental and physical health of patients have a significant impact on both subjective and objective clinical outcomes and healthcare professionals should take these aspects into account.

Increased Cellular Dosage of Bone Marrow Aspiration Concentrate Does Not Translate to Increased Clinical Effectiveness in Knee Osteoarthritis: A Phase I Dose Escalation Study.

Knee osteoarthritis (KOA), a chronic degenerative disease, significantly impairs quality of life due to pain and mobility limitations. Traditional treatments focus on symptom management without addressing the underlying disease progression, leading to a growing interest in regenerative medicine approaches. Bone marrow aspirate concentrate (BMAC), rich in mesenchymal stem cells and growth factors, has shown potential for cartilage repair and symptom relief in KOA. Despite promising outcomes, the optimal BMAC dosage for knee OA treatment remains undetermined. This study aims to evaluate the clinical efficacy and safety of varying BMAC dosages in knee OA treatment. This prospective controlled dose-escalation study involved 75 patients with early-stage knee OA, categorized into three groups based on BMAC dosage administered 10 × 106 cells (low-dose group), 50 × 106 cells (medium-dose group), or 100 × 106 cells (high-dose group). All the patients underwent a single intra-articular injection of BMAC and were monitored over a year. The primary outcomes include Visual Analog Scale (VAS) for pain and the Knee Injury and Osteoarthritis Outcome Score (KOOS) for joint function recorded at baseline, 1, 3, 6, and 12months post-intervention. Adverse events were also documented. Significant clinical improvements in VAS and KOOS scores were noted across all groups at all time points compared to the baseline. However, these improvements did not significantly differ between dosage groups throughout the follow-up period. Adverse effects were minimal and primarily consisted of transient post-injection pain and effusion, with no dose-dependent increase in complications. BMAC treatment for knee OA is safe and demonstrates potential for significant pain relief and functional improvement, irrespective of the dosage administered within the tested range. The lack of significant differences among varying dosages suggests a plateau in therapeutic efficacy beyond a certain threshold. Further research is necessary on the long-term outcomes to optimize the dosing strategy.

Abnormalities of cortical stimulation strength-duration time constant in amyotrophic lateral sclerosis

ObjectivesStrength-duration time constant (SDTC) may now be determined for cortical motor neurones, with activity mediated by transient Na+ conductances. The present study determined whether cortical SDTC is abnormal and linked to the pathogenesis of amyotrophic lateral sclerosis. MethodsCortical SDTC and rheobase were estimated from 17 ALS patients using a controllable pulse parameter transcranial magnetic stimulation (cTMS) device. Resting motor thresholds (RMTs) were determined at pulse widths (PW) of 30, 45, 60, 90 and 120 µs and M−ratio of 0.1, using a figure-of-eight coil applied to the primary motor cortex. ResultsSDTC was significantly reduced in ALS patients (150.58 ± 9.98 µs; controls 205.94 ± 13.7 µs, P < 0.01). The reduced SDTC correlated with a rate of disease progression (Rho = -0.440, P < 0.05), ALS functional rating score (ALSFRS-R) score (Rho = 0.446, P < 0.05), and disease duration (R = 0.428, P < 0.05). The degree of change in SDTC was greater in patients with cognitive abnormalities as manifested by an abnormal total Edinburgh Cognitive ALS Screen score (140.5 ± 28.7 µs, P < 0.001) and ALS-specific subscore (141.7 ± 33.2 µs, P = 0.003). ConclusionsCortical SDTC reduction was associated with a more aggressive ALS phenotype, or with more prominent cognitive impairment. SignificanceAn increase in transient Na+ conductances may account for the reduction in SDTC, linked to the pathogenesis of ALS.
