Advanced Multi-Layer Watertight Closure versus Conventional Closure in Total Hip and Knee Replacement Surgery.

Background: In total joint replacement procedures, surgeons have increasingly adopted advanced multi-layer, watertight closure. The objective of the study was to compare the clinical and economic outcomes for advanced multi-layer, watertight closure patients to those with conventional closure with sutures and skin staples.

Methods: Patients aged ≥18 years were included in the study if they underwent total joint arthroplasty of the hip or knee as an elective, primary, inpatient procedure between January 2014 and March 2019.

Robotic-assisted total knee arthroplasty reduces soft-tissue releases which improves functional outcomes: A retrospective study.

Background: There is increasing use of Robotic-Assisted (RA) and personalized alignment techniques in total knee arthroplasty (TKA). The hypothesis of this study was that RA TKA would result in fewer soft-tissue releases, and that fewer soft-tissue releases would be associated with improved clinical outcomes.

Methods: A retrospective review of an internal company registry was conducted for all primary TKAs performed from Jan 1, 2014, through a database extract date of Nov 4, 2022.

Five-Year Survivorship of Total Hip Arthroplasty With a Proximally Coated, Medially Collared, Triple-Tapered Femoral Stem: A Retrospective, Multicenter Registry Review.

Background The anterior approach for total hip arthroplasty (THA) has gained popularity in recent years. Some surgeons have been hesitant to adopt the approach due to concerns over increased complications such as intraoperative fracture, stem loosening, and stem revision. This study aims to evaluate the all-cause revision rate and survivorship of a collared, triple-tapered stem that was designed specifically for use with the anterior approach in THA to enhance outcomes and reduce adverse events.

Material Flow Analysis and Occupational Exposure Assessment in Additive Manufacturing End-of-Life Material Management.

Additive manufacturing (AM) offers a variety of material manufacturing techniques for a wide range of applications across many industries. Most efforts at process optimization and exposure assessment for AM are centered around the manufacturing process. However, identifying the material allocation and potentially harmful exposures in end-of-life (EoL) management is equally crucial to mitigating environmental releases and occupational health impacts within the AM supply chain.

Sulforaphane Bioavailability in Healthy Subjects Fed a Single Serving of Fresh Broccoli Microgreens.

Cruciferous vegetable consumption is associated with numerous health benefits attributed to the phytochemical sulforaphane (SFN) that exerts antioxidant and chemopreventive properties, among other bioactive compounds. Broccoli sprouts, rich in SFN precursor glucoraphanin (GRN), have been investigated in numerous clinical trials. Broccoli microgreens are similarly rich in GRN but have remained largely unexplored.

Review of generic scenario environmental release and occupational exposure models used in chemical risk assessment.

Under the Toxic Substances Control Act (TSCA), the United States Environmental Protection Agency (USEPA) is required to determine whether a new chemical substance poses an unreasonable risk to human health or the environment before the chemical is manufactured in or imported into the United States. This manuscript provides a review of the process used to evaluate the risk associated with a chemical based on the scenarios and models used in the evaluation. Specifically, the Generic Scenarios and Emission Scenario Documents developed by the USEPA were reviewed, along with background documentation prepared by USEPA to identify the core elements of the environmental release and occupational exposure scenarios used to assess the risk of the chemical being evaluated.

Sunrise of PFAS Replacements: A Perspective on Fluorine-Free Foams.

One type of firefighting foam, referred to as aqueous filmforming foams (AFFF), is known to contain per- and polyfluoroalkyl substances (PFAS). The concerns raised with PFAS, and their potential environmental and health impacts, have led to a surge in research on fluorine-free alternatives both in the United States and globally. Particularly, in January 2023, a new military specification (MIL-PRF-32725) for fluorine-free foam was released in accordance with Congressional requirements for the U.

Distribution and Frequency of Salivary Gland Tumours: An International Multicenter Study.

Background: Salivary gland tumours (SGT) are a relatively rare group of neoplasms with a wide range of histopathological appearance and clinical features. To date, most of the epidemiological studies on salivary gland tumours are limited for a variety of reason including being out of date, extrapolated from either a single centre or country studies, or investigating either major or minor glands only.

Methods: This study aimed to mitigate these shortcomings by analysing epidemiological data including demographic, anatomical location and histological diagnoses of SGT from multiple centres across the world.

A phase I/II trial of concurrent immunotherapy with chemoradiation in locally advanced larynx cancer.

Objectives: Cisplatin-based chemoradiation is an established organ-preserving strategy for locally advanced laryngeal cancer, but long-term survival remains suboptimal. Immunotherapy has been studied in the metastatic and unresectable recurrent settings. However, additional data are needed to assess its role in organ preservation for locally advanced laryngeal cancer.

Consensus Statement on Proton Therapy for Prostate Cancer.

Proton therapy is a promising but controversial treatment in the management of prostate cancer. Despite its dosimetric advantages when compared with photon radiation therapy, its increased cost to patients and insurers has raised questions regarding its value. Multiple prospective and retrospective studies have been published documenting the efficacy and safety of proton therapy for patients with localized prostate cancer and for patients requiring adjuvant or salvage pelvic radiation after surgery.

Microsecretory Adenocarcinoma of Salivary Glands: An Expanded Series of 24 Cases.

Microsecretory adenocarcinoma (MSA) is a recently described salivary gland tumor with a characteristic histologic and immunophenotypic profile and recurrent MEF2C-SS18 fusions. Because only six cases of MSA have been published, its complete clinicopathologic spectrum is unclear, and its biologic behavior has not been documented. Here, we present an updated and expanded experience of 24 MSA cases.

Ultra-long-term toxicity of prostate brachytherapy.

Purpose: The true long-term toxicity associated with most radiation treatments is unknown. Prostate cancer patients survive decades after prostate cancer brachytherapy, with unclear long-term toxicity profiles. We therefore evaluated prostate cancer patients who had received I-125 brachytherapy treatment (14,400 cGy) 14-24 years prior and assessed their long-term quality of life based on urinary, bowel, and sexual function.

A complex resistance locus in Solanum americanum recognizes a conserved Phytophthora effector.

Late blight caused by Phytophthora infestans greatly constrains potato production. Many Resistance (R) genes were cloned from wild Solanum species and/or introduced into potato cultivars by breeding. However, individual R genes have been overcome by P.

Ketamine: a versatile tool for anesthesia and analgesia.

Purpose Of Review: Ketamine has been used for decades for a variety of indications. Beyond the historical benefits and effects of ketamine, newer developments have occurred worthy of an update. This review will discuss common uses and indications for ketamine in the perioperative setting, as well as highlight newer indications in recent years.

The Impact of a Multidisciplinary Third-Year Oncology Elective Rotation on Decisions to Pursue Oncologic Careers and Oncology Exposure.

Purpose: The majority of oncologic care is provided in the outpatient setting, yet at many medical schools, the dominant means of exposure to oncology occurs during inpatient rotations. Given the multidisciplinary nature of the specialty, radiation oncology departments are well positioned to lead outpatient oncology rotations within medical schools. Since 1992, the University of Cincinnati's Department of Radiation Oncology has administered a 2-week, third-year clinical oncology elective.

Linking Molecular Structure via Functional Group to Chemical Literature for Establishing a Reaction Lineage for Application to Alternatives Assessment.

The evaluation of potential alternatives for chemicals of concern (CoC) requires an understanding of their potential human health and environmental impacts during the manufacture, use, recycle and disposal life stages. During the manufacturing phase, the processes used to produce a desired chemical are defined based on the sequence of chemical reactions and unit operations required to produce the molecule and separate it from other materials used or produced during its manufacture. This paper introduces and demonstrates a tool that links a chemical's structure to information about its synthesis route and the manufacturing process for that chemical.

Validation of NRG oncology/RTOG-0129 risk groups for HPV-positive and HPV-negative oropharyngeal squamous cell cancer: Implications for risk-based therapeutic intensity trials.

Background: Radiation Therapy Oncology Group (RTOG)-0129 recursive partitioning analysis was the basis for risk-based therapeutic intensification trials for oropharyngeal cancer (OPC). To the authors' knowledge, the question of whether RTOG-0129 overall survival (OS) estimates for low-risk, intermediate-risk, and high-risk groups are similar in other data sets or applicable to progression-free survival (PFS) is unknown. Therefore, the authors evaluated whether survival differences between RTOG-0129 risk groups persist at 5 years, are reproducible in an independent clinical trial, and are applicable to PFS, and whether toxicities differ across risk groups.

Prospective, Randomized Study of Direct Anterior Approach vs Posterolateral Approach Total Hip Arthroplasty: A Concise 5-Year Follow-Up Evaluation.

Background: Interest in direct anterior approach (DAA) has increased over the last decade. In our previously published study comparing DAA to posterolateral approach (PA), early 3-month benefits were noted in terms of pain and function. There was no difference noted at 6 or 12 months.

Purpose-Driven Reconciliation of Approaches to Estimate Chemical Releases.

A framework is presented to address the toolbox of chemical release estimation methods available for manufacturing processes. Although scientists and engineers often strive for increased accuracy, the development of fit-for-purpose release estimates can speed results that could otherwise delay decisions important to protecting human health and the environment. A number of release estimation approaches are presented, with the newest using decision trees for regression and prediction.

Enhanced phosphatidylserine-selective cancer therapy with irradiation and SapC-DOPS nanovesicles.

Normal living cells exhibit phosphatidylserine (PS) primarily within the intracellular leaflet of the plasma membrane. In contrast, viable cancer cells have high levels of PS on the external surface, and exhibit a broad range of surface PS, even within specific types of cancer. Agents that target surface PS have recently been developed to treat tumors and are expected to be more effective with higher surface PS levels.
