ABSTRACT

PURPOSE: Hidden blood loss (HBL) during the perioperative period significantly impacts postoperative recovery and complications, yet it is frequently disregarded. This study aimed to investigate the effects of tip-apex distance (TAD) and calcar-referenced tip-apex distance (calTAD) on HBL in the treatment of intertrochanteric fractures utilizing proximal femoral nail antirotation (PFNA). The study also seeks to evaluate the possible decrease in HBL subsequent to PFNA treatment by optimizing nail positioning.

METHOD: A historical cohort study was conducted from January 2020 to December 2022. Patients diagnosed with unilateral acute closed femoral intertrochanteric fracture and who underwent PFNA internal fixation surgery met the inclusion criteria, and were grouped according to the value of calTAD and TAD. The participants were divided into low TAD group (TAD<20 mm) and high TAD group (TAD≥20 mm); low calTAD group (calTAD<7.625 mm) and high calTAD group (calTAD≥7.625 mm), respectively. The primary outcome measures were intraoperative blood loss (including HBL, overt blood loss, and total blood loss). Continuous data were analyzed using an independent sample t-test or Mann-Whitney U test, and categorical data were analyzed using the Pearson Chi-square test. Univariate analysis was used to evaluate the association between various indicators and perioperative HBL. A stepwise multiple linear regression analysis model was used to determine the independent factors affecting perioperative HBL. A p value less than 0.05 was considered statistically significant.

RESULTS: A total of 131 patients were initially included, of which 80 were assigned to the calTAD group (with 61 in the high calTAD group and 19 in the low calTAD group), and 80 were assigned to the TAD group (with 34 in the high TAD group and 46 in the low TAD group). The average HBL for the low TAD group was 772.85 mL, whereas for the high TAD group it was 919.68 mL (p>0.05). The average HBL for the low calTAD group was 611.42 mL, whereas for the high calTAD group it was 904.97 mL (p<0.05). Subsequent analysis revealed that the patient’s height, preoperative hemoglobin levels, changes in hemoglobin and hematocrit levels from pre- to post-surgery, and calTAD are independent risk factors influencing HBL.

CONCLUSION: In summary, our investigation revealed a significant correlation between the positioning of nails in PFNA and HBL during the perioperative period. By optimizing the placement of the cephalic nail, specifically by ensuring a calTAD of less than 7.625 mm, a significant decrease in HBL can be attained. Additionally, we identified that height, preoperative hemoglobin, differences in preoperative and postoperative hemoglobin and hematocrit, and the positioning of the cephalic nail were independent risk factors for HBL.

ABSTRACT

BACKGROUND: Tumor-infiltrating lymphocytes (TILs), assessed by visual examination (VE), are prognostic and predictive in early-stage triple-negative breast cancer (TNBC). Computational assessment (CA) may provide a complementary approach. We evaluated the prognostic value of TILs by VE and CA.

METHODS: TBCRC 030 was a randomized phase II trial enrolling patients with BRCA1/2-proficient stage I-III TNBC to receive preoperative cisplatin or paclitaxel. The primary endpoint was pathologic response at surgery. TILs were visually scored on digitized pre-treatment biopsies per International TILs Working Group recommendations. CA used the 4D QPOR platform to generate TILs, immune heterogeneity index (IHI), and a combined immune/cell cycle biomarker (CmbI). Predictive performance for residual cancer burden (RCB) 0/1 was assessed using ROC curves and odds ratios (ORs) with 95% CIs; all statistical tests were two-sided.

RESULTS: Of 139 response-evaluable patients, 121 had matched VE and CA data (59 cisplatin, 62 paclitaxel). Median VE TILs were higher in responders (40.0% vs. 10.0%, p = .002) and predicted response (OR 1.86, 95% CI 1.24-2.87, AUC 0.69, 95% CI 0.57-0.80). CA CmbI differed by response group and predicted RCB 0/1 (OR 3.20, 1.05-11.07; AUC 0.62, 0.51-0.73). CA TILs and IHI were not predictive. VE TILs and CA CmbI predicted response to paclitaxel (OR 2.91, 1.56-6.14; OR 9.17, 2.01-66.39, respectively), but not to cisplatin.

CONCLUSION: VE TILs and CA CmbI were each associated with response to NAC in TNBC in the overall cohort and the paclitaxel arm. CA CmbI did not outperform visual assessment. Further validation is needed before clinical implementation of computational approaches.

ABSTRACT

MOTIVATION: Differential expression analysis plays a vital role in omics research enabling precise identification of features that associate with different phenotypes. This process is critical for uncovering biological differences between conditions, such as disease versus healthy states. In proteomics, several statistical methods have been used, ranging from simple t-tests to more advanced methods like DEqMS, limma and ROTS. However, a flexible method for reproducibility-optimized statistics tailored for clinical omics data has been lacking.

RESULTS: In this study, we developed LimROTS, a hybrid method that integrates a linear regression model and the empirical Bayes approach with the Reproducibility-Optimized Statistics, to create a novel moderated ranking statistic, for robust and flexible analysis of proteomics data. We validated its performance using twenty-one proteomics gold standard spike-in datasets with different protein mixtures, MS instruments, and techniques for benchmarking. This hybrid approach improves accuracy and reproducibility of complex proteomics data, making LimROTS a powerful tool for high-dimensional omics data analysis.

AVAILABILITY: LimROTS has been implemented as an R/Bioconductor package, available at https://bioconductor.org/packages/LimROTS/. Additionally, the code used in this study is available in GitHub repository https://github.com/AliYoussef96/LimROTSmanuscript.

ABSTRACT

MOTIVATION: Understanding the genetic basis of drug-induced toxicity is crucial for drug development. In-silico analysis of toxicogenomics datasets facilitates early detection of toxicity biomarkers. However, existing tools struggle with the complex interdependencies among hierarchically structured variables, leading to inaccurate biomarker identification. To address this limitation, we developed a Hierarchical Linear Model (HLM) and implemented it in the R package ToxAssay, offering extensive functionality for comprehensive toxicity assessment.

RESULTS: ToxAssay outperforms existing methods by improving biomarker detection and computational efficiency. Applied to glutathione depletion-induced toxicity, it prioritized 71 key genes and identified 26 core genes with high discriminative accuracy (AUC = 0.97) and strong cross-correlation (Pearson’s r = 0.88) with external datasets. Additionally, our advance outcome pathway (AOP) analysis algorithm uncovered disease outcomes linked to glutathione depletion. These findings provide precise insights into the molecular mechanisms driving drug-induced toxicity.

AVAILABILITY: ToxAssay is available as an open-source R package at https://github.com/Fun-Gene/toxassay.

ABSTRACT

INTRODUCTION/OBJECTIVE: Respiratory muscle function may be impaired in axial spondyloarthritis (axSpA) due to mechanical limitations of the thoracic spine and chest wall. However, the extent of respiratory muscle weakness and its clinical associations remain largely underexplored.

METHODS: This comparative cross-sectional study included 51 patients with radiographic axSpA (r-axSpA) and 52 healthy controls. Maximal inspiratory (PI_max) and expiratory (PE_max) pressures were measured using standardized protocols. Patients with r-axSpA also underwent assessments of pulmonary functions (forced vital capacity (FVC), forced expiratory volume in the first second (FEV₁)), spinal pain, disease activity, spinal mobility, functional status, physical performance, quality of life, anxiety/depression, and fatigue. Subgroup analyses were performed based on the presence of respiratory muscle weakness (< 80% of predicted PI_max and PE_max), and stepwise multiple regression was used to identify clinical predictors of PI_max.

RESULTS: Although the PI_max (mean difference: – 8.6% [95% CI: – 21.7% to 4.6%]) and PE_max (mean difference: – 4.6% [95% CI: – 16.7% to 7.5%]) were lower in the r-axSpA group, the differences were not statistically significant (p > 0.05). Seventeen patients (33.3% of the total sample) with r-axSpA exhibited inspiratory muscle weakness. This subgroup demonstrated significantly poorer FVC, spinal pain at rest, spinal mobility, and quality of life (p < 0.05). Regression analysis revealed that pain at rest (β = – 0.317, p = 0.013) and FVC (β = 0.296, p = 0.022) independently predicted 19.2% of the variance in PI_max.

CONCLUSION: Although respiratory muscle strength was mostly preserved in r-axSpA, a substantial subgroup exhibited inspiratory muscle weakness associated with adverse clinical outcomes. Identifying these patients may guide tailored interventions for optimal care.

KEY POINTS: A substantial proportion of patients with radiographic axSpA demonstrate inspiratory muscle weakness despite preserved average respiratory pressures. Patients with inspiratory muscle weakness exhibit diminished lung volumes, decreased spinal mobility, higher pain levels, and poorer quality of life compared to those without weakness. Inspiratory muscle strength is independently predicted by spinal pain at rest and forced vital capacity.

ABSTRACT

OBJECTIVE: Axial spondyloarthritis (AxSpA) and Behçet’s disease (BD) have clinical and HLA locus overlap and have been grouped under MHC-I-opathy. This study aimed to identify overlapping loci between AxSpA and BD to help elucidate MHC-I-opathy pathogenesis.

METHODS: Association clustering methods, such as OASIS, reduce the multiple-testing burden and are more powerful than single variant analysis for identifying modest genetic effects. Two large publicly available genome-wide association studies (GWAS) of AxSpA (921 cases, 907 controls) and BD (1215 cases and 1278 healthy controls) from Turkiÿe were subjected to OASIS meta-analyses to identify common non-HLA loci. Statistics used to identify significant loci included the novel OASIS locus index (OLI). Expression analysis was performed using GEO datasets, GSE181364 for AxSpA and GSE209567 for BD. STRING network analysis was performed.

RESULTS: GWAS for both diseases had the highest significance at the HLA-I locus. Of the 234 independent modestly significant non-HLA loci, there were 15 loci common to both AxSpA and BD. These included known MHC-I-opathy loci, 1p31.3 for IL23R (P = 5.37 × 10^-6, OLI = 52.7) and 13q14.11 for LACC1 (P = 7.41 × 10^-6, OLI = 65.3). A novel locus identified in this study is 3p21.31 containing CXCR6 (P = 2.46 × 10^-5, OLI = 25.8). The locus 3p22.3 had the highest overall OLI (81.3), and the most significant SNP at this locus (rs2291897; P = 1.82 × 10^-5) is an intronic variant in the gene FBXL2. However, this association was specific for BD only.

CONCLUSION: Several loci containing pathologically relevant genes for MHC-I-opathy were identified here, using a cluster-based approach in AxSpA and BD GWAS, with CXCR6 being a novel target. Key Points • MHC-I-opathy immunopathogenesis is incompletely understood and challenged by risk genes of modest effect. • This meta-analysis identified 15 loci common to both AxSpA and BD that may provide diagnostic and therapeutic targets for MHC-I-opathy. • Major candidate genes for MHC-I-opathy identified here are IL23R, LACC1, and CXCR6. • FBXL2 was associated strongly with BD by OASIS analysis.

ABSTRACT

Minimally invasive neurosurgery presents specific challenges due to the limited operative space and complex cranial anatomy, requiring highly precise and safe surgical guidance. Augmented Reality (AR) technology offers the potential to improve surgical accuracy and safety by overlaying critical digital information onto real-world surgical environments. In this study, we present a study that aims to compare four AR visualization methods-2D flat display, smart tablet, head-mounted display (HMD), and 3D autostereoscopic display-in guiding minimally invasive neurosurgical procedures, specifically focusing on ventriculocentesis. The effectiveness of the AR methods was evaluated through comprehensive user studies involving 32 participants (including 11 experienced surgeons), with assessment focused on critical performance metrics including accuracy, completion time, usability, and cognitive workload during simulated surgical procedures. Results demonstrated that 3D visualization methods significantly outperformed traditional 2D approaches in terms of puncture accuracy and angular precision. Specifically, surgeons showed a statistically significant improvement in localization accuracy, with mean error reduced from 2.69 mm to 1.67 mm, and angular deviation from 5.62° to 1.54°. In comparing the two 3D visualization systems, the HMD exhibited superior task completion efficiency, while the 3D autostereoscopic display demonstrated higher usability scores and lower perceived workload ratings. Notably, the 3D systems effectively reduced the performance disparity between novice and experienced practitioners, suggesting their potential to accelerate the learning curve for less experienced users. We conclude that AR holds significant potential to enhance performance and decision-making in minimally invasive neurosurgical guidance.

ABSTRACT

PURPOSE: This study evaluated the feasibility, acceptability, usability, and HPV vaccine completion rate of the Now I Know (NIK) mHealth intervention to promote HPV vaccine completion among minority and low-income young women.

METHODS: This quasi-experimental pilot study recruited 35 women aged 18-26 at two federally supported outpatient clinics in a large city in the Northeastern United States. Participants were allocated to two groups: 24 received the NIK intervention plus usual care and 11 received usual care only. After completing a baseline assessment, intervention group participants launched the NIK mobile app, which entailed HPV vaccine education, self-managed vaccine record & reminder, and Q&A features. Follow-up visits were conducted at 2 and 6 months. Feasibility was assessed through screening, recruitment, fidelity, and retention. Acceptability and usability were evaluated via survey and exit interview. The primary outcome-HPV vaccine 3-dose series completion-was analyzed using descriptive statistics.

RESULTS: This study demonstrated feasibility by reaching the recruitment target (n = 35) and high retention rate (89%). Participants reported the app was acceptable, appreciating reliable information, convenient access, providing a personal touch, and raising awareness. Regarding usability, users found the app easy to navigate, accessible, well organized, and user-friendly. The HPV vaccine completion rate was higher in the intervention group (55%) than in the usual care group (45.5%).

CONCLUSION: Findings showed improved vaccination completion among those using the Now I Know mHealth intervention (compared to usual care), acceptability of the intervention, and feasibility of recruiting, retaining, and delivering the intervention to promote HPV vaccine completion among young women in federally subsidized healthcare settings.

ABSTRACT

OBJECTIVES: This study evaluated the mechanical and surface characteristics of the transition zone of multilayered translucent zirconia (TZ) after aging and analyzed the correlation between the 4-point bending flexural strength (4PBFS) and biaxial flexural strength (BFS) in each zone.

METHODS: Traditional (3Y-TZP of LT; L, 4Y-TZP of MT; M) and multilayered TZ (5Y-TZP of MT Multi; T, 3Y/5Y-TZP of Prime; P, 4Y/5Y-TZP of Prime esthetic; E) IPS E.max ZirCAD blocks were used to fabricate 525 disk-shaped and 300 bar-shaped specimens. Specimens were separated into three groups, aged in an autoclave at 134 °C under 0.2 MPa for 0 h, 5 h, and 10 h. The mechanical and surface characteristics of the transition zone in multilayered TZ were analyzed, following statistical analyses (α = 0.05).

RESULTS: L showed the highest 4PBFS and BFS, irrespective of aging. Consistent correlations between the 4PBFS and BFS were found in all groups. L showed the highest Weibull characteristic strength under all conditions. T showed the highest nanoindentation hardness and Young’s modulus, and the Vickers hardness of L and P were lower than other groups. Aging led to surface uplifts and microcracks caused by phase transformation, particularly in L and P.

CONCLUSIONS: The flexural strength of 3Y/5Y-TZP and 4Y/5Y-TZP was comparable to that of 3Y-TZP and 4Y, 5Y-TZP respectively, regardless of aging. Surface roughness showed a marked increase after aging in 3Y-TZP and 3Y/5Y-TZP. Furthermore, the interaction between yttria content and aging was evident across all mechanical and surface characteristics, except for flexural strength.

ABSTRACT

Global population aging is increasing the demand for Long-Term Care Facilities to support older adults with complex health needs. The Prescription Day LTCFs project is a national multicenter point-prevalence study, conducted by the Italian Society of Gerontology and Geriatrics in collaboration with the ANASTE Humanitas Foundation, investigated medication prescription patterns and administration practices in 3,400 residents across 82 facilities in Italy. Participants had a mean age of 84.7 years, with a high prevalence of frailty (49.7%) and polypharmacy (84.8% taking five or more medications). Common chronic conditions included hypertension, dementia, and dysphagia. The study highlighted the complexity of pharmacological regimens, emphasizing risks related to potentially inappropriate medications, drug-drug interactions, and frequent modifications of solid oral dosage forms to facilitate administration in residents with swallowing difficulties or cognitive impairment. These complexities contribute to increased nursing workload. Despite advances in deprescribing research, polypharmacy remains highly prevalent, underlining the need for tailored prescribing guidelines. Variability among Long Term Care Facilities reflects differences in organization and regional healthcare frameworks. The findings provide a valuable foundation for developing strategies to optimize medication management, enhance safety, and improve quality of care in Italian Long Term Care Facilities. This study also offers insights to inform healthcare policies and best practices in pharmacological care for older adults in Long Term Care settings.
