Indications for the addition of a patellofemoral joint arthroplasty following a previous unicondylar knee arthroplasty- a literature review and Delphi consensus.

Introduction: The aim of this study was to establish an international consensus statement on the indications for the addition of a patellofemoral joint arthroplasty (PFJA) in patients with a unicondylar knee arthroplasty (UKA) and symptomatic progression of patellofemoral compartment osteoarthritis.

Materials And Methods: A systematic review of the literature was conducted, and the results used to inform the development of a statement by an expert working group. This was then evaluated and modified, using a Delphi process, by members of the European Knee Society (EKS).

h-CMD: An efficient hybrid fast centroid and quasi-centroid molecular dynamics method for the simulation of vibrational spectra.

Developing efficient path integral (PI) methods for atomistic simulations of vibrational spectra in heterogeneous condensed phases and interfaces has long been a challenging task. Here, we present the h-CMD method, short for hybrid centroid molecular dynamics, which combines the recently introduced fast quasi-CMD (f-QCMD) method with fast CMD (f-CMD). In this scheme, molecules that are believed to suffer more seriously from the curvature problem of CMD, e.

Covalent Proximity Inducers.

Molecules that are able to induce proximity between two proteins are finding ever increasing applications in chemical biology and drug discovery. The ability to introduce an electrophile and make such proximity inducers covalent can offer improved properties such as selectivity, potency, duration of action, and reduced molecular size. This concept has been heavily explored in the context of targeted degradation in particular for bivalent molecules, but recently, additional applications are reported in other contexts, as well as for monovalent molecular glues.

Characterization of Somatostatin Receptor 2 Gene Expression and Immune Landscape in Sinonasal Malignancies.

Olfactory neuroblastoma (ONB), sinonasal undifferentiated carcinoma (SNUC), and sinonasal neuroendocrine carcinoma (SNEC) are rare malignancies arising from the sinonasal tract with limited therapeutic options. The expression of the somatostatin receptor 2 gene (), which is expressed in other neuroendocrine neoplasms and is therapeutically actionable, has been reported in these tumors. Here, we analyzed gene expression and its associations with genomic features, established biomarkers predicting of immune response, and the tumor immune microenvironment in a cohort of ONB, SNUC, and SNEC tumor samples (26, 13, and 8 samples, respectively) from a real-world database.

Peri-operative complications following endoscopic-assisted transoral resection of parapharyngeal space tumors: retrospective analysis of 100 patients.

Purpose: A transoral surgical corridor can provide adequate exposure for extirpation of benign tumors arising from the parapharyngeal space (PPS). However, peri-operative complications following a transoral approach to the PPS have not been sufficiently described. This study retrospectively reviewed patients with PPS tumor extirpated via an endoscopic-assisted transoral approach, aiming to evaluate the safety of this approach and summarize the peri-operative complications.

Clinical Use of Home OCT Data to Manage Neovascular Age-Related Macular Degeneration.

To investigate how home optical coherence tomography (OCT) influences the clinical decision-making of retina specialists for the management of neovascular age-related macular degeneration (nAMD). In this retrospective imaging review, 15 retina specialists each evaluated 10 home OCT data segments from 29 eyes being treated for nAMD. Based on OCT data, indications were identified for when eyes should be treated, which antivascular endothelial growth factor should be used, and the specific retinal fluid and time thresholds for notification.

Lower survival for surgical treatment of HPV-related oropharynx cancer at community cancer centers.

Background: The rate of primary surgery for human papillomavirus-related oropharynx cancer (HPVOPC) has recently declined, while utilization of transoral robotic surgery (TORS) has lagged at community cancer centers (CCs). We hypothesize that differences in overall survival (OS) exist between patients undergoing surgery for HPVOPC at CCs and low (<15 TORS/year; LVACs) and high (≥15 TORS/year; HVACS) TORS volume academic centers.

Methods: Cases from the US National Cancer Database with a diagnosis of HPVOPC from 2010-2019 that underwent primary surgical treatment were included.

Dual targeting of histone deacetylases and MYC as potential treatment strategy for H3-K27M pediatric gliomas.

Diffuse midline gliomas (DMGs) are aggressive and fatal pediatric tumors of the central nervous system that are highly resistant to treatments. Lysine to methionine substitution of residue 27 on histone H3 (H3-K27M) is a driver mutation in DMGs, reshaping the epigenetic landscape of these cells to promote tumorigenesis. H3-K27M gliomas are characterized by deregulation of histone acetylation and methylation pathways, as well as the oncogenic MYC pathway.

Molecular patterns and mechanisms of tumorigenesis in HPV-associated and HPV-independent sinonasal squamous cell carcinoma.

Unlabelled: Mechanisms of tumorigenesis in sinonasal squamous cell carcinoma (SNSCC) remain poorly described due to its rare nature. A subset of SNSCC are associated with the human papillomavirus (HPV); however, it is unknown whether HPV is a driver of HPV-associated SNSCC tumorigenesis or merely a neutral bystander. We hypothesized that performing the first large high-throughput sequencing study of SNSCC would reveal molecular mechanisms of tumorigenesis driving HPV-associated and HPV-independent SNSCC and identify targetable pathways.

Mean-Field Ring Polymer Rates Using a Population Dividing Surface.

Mean-field ring polymer molecular dynamics offers a computationally efficient method for the simulation of reaction rates in multilevel systems. Previous work has established that, to model a nonadiabatic state-to-state reaction accurately, it is necessary to ensure reactive trajectories form kinked ring polymer configurations at the dividing surface. Building on this idea, we introduce a population difference coordinate and a reactive flux expression modified to only include contributions from kinked configurations.

Anti-VEGF Pharmaceutical Prior Authorization in Retina Practices.

Importance: Anti-vascular endothelial growth factor (VEGF) intravitreal injections, a mainstay of treatment for many retinal diseases to optimize visual outcomes, have been included in prior authorization (PA) initiatives. However, if clinicians are extremely accurate in their use of anti-VEGF medications, such administrative burdens may need reconsideration.

Objective: To quantify PA for anti-VEGF medications (aflibercept, ranibizumab, and bevacizumab) that were approved and determine associated administrative burdens experienced by retina practices.

Epidemiologic Trends in Human Papillomavirus-Associated Sinonasal Squamous Cell Carcinoma.

Importance: Sinonasal squamous cell carcinoma (SNSCC) is the most commonly encountered cancer within the sinonasal cavity. Ongoing research has sought to ascertain the potential role of human papillomavirus (HPV) in the pathogenesis of SNSCC.

Objective: To assess trends in HPV-associated and HPV-independent SNSCC over time, including assessment of clinical demographics, treatment patterns, and survival.

Air pollution, genetic factors, and chronic rhinosinusitis: A prospective study in the UK Biobank.

Background: Chronic rhinosinusitis (CRS) is a prevalent upper respiratory condition that manifests in two primary subtypes: CRS with nasal polyps (CRSwNP) and CRS without nasal polyps (CRSsNP). While previous studies indicate a correlation between air pollution and CRS, the role of genetic predisposition in this relationship remains largely unexplored. We hypothesized that higher air pollution exposure would lead to the development of CRS, and that genetic susceptibility might modify this association.

Augmentation of tumor expression of HLA-DR, CXCL9, and CXCL10 may improve olfactory neuroblastoma immunotherapeutic responses.

Background: Olfactory neuroblastoma is a rare malignancy of the anterior skull base typically treated with surgery and adjuvant radiation. Although outcomes are fair for low-grade disease, patients with high-grade, recurrent, or metastatic disease oftentimes respond poorly to standard treatment methods. We hypothesized that an in-depth evaluation of the olfactory neuroblastoma tumor immune microenvironment would identify mechanisms of immune evasion in high-grade olfactory neuroblastoma as well as rational targetable mechanisms for future translational immunotherapeutic approaches.

Chordoma cancer stem cell subpopulation characterization may guide targeted immunotherapy approaches to reduce disease recurrence.

Introduction: Cancer stem cells (CSCs), a group of tumor-initiating and tumor-maintaining cells, may be major players in the treatment resistance and recurrence distinctive of chordoma. Characterizing CSCs is crucial to better targeting this subpopulation.

Methods: Using flow cytometry, six chordoma cell lines were evaluated for CSC composition.

Higher order aberrations in keratoconus‏.

Introduction: Keratoconus is a progressive disorder of the cornea that causes thinning (Sedaghat et al. in Sci Rep 11(1):11971, 2021), ectasia, and irregular astigmatism, resulting in poor visual acuity that cannot be corrected with standard sphero-cylindrical spectacle lenses. One feature distinguishing keratoconic corneas is ocular aberrations, manifesting up to five or six times the amount of higher-order aberrations than a normal, healthy eye.

Targeting sinonasal undifferentiated carcinoma with a combinatory immunotherapy approach.

Purpose: Sinonasal undifferentiated carcinoma (SNUC) is a rare, aggressive malignancy of the sinonasal cavity with poor prognosis and limited treatment options. To investigate the potential for SNUC sensitivity to combinatory immunotherapy, we performed in vitro studies with SNUC cell lines and used multi-spectral immunofluorescence to characterize the in vivo patient SNUC tumor immune microenvironment (TIME).

Experimental Design: Human-derived SNUC cell lines were used for in vitro studies of tumor cell susceptibility to natural killer (NK) cell-based immunotherapeutic strategies.
