Bacterial biofilms represent a formidable challenge in the treatment of chronic wounds, largely because of their resistance to conventional antibiotics. The emergence of multidrug-resistant (MDR) bacterial strains exacerbates this issue, necessitating a shift towards exploring alternative therapeutic approaches. In response to this urgent need, there has been a surge in research efforts aimed at identifying effective non-antibiotic treatments.

CABG Should Be a Subspecialty.

Semin Thorac Cardiovasc Surg

December 2024

University of California Davis, Sacramento, CA, 2 University of Maryland, Baltimore, MD.

Subspecialization in surgery is increasingly common and for great reasons. Over the past twenty years, there is evidence in support of link between sub-specialization in the disciplines of orthopedic surgery, general, thoracic surgery, neurosurgery, and in interventional cardiology and better patient outcomes and technical advances in their respective fields. In addition, studies suggest increased hospital and surgeon volume throughout surgery may lead to improved surgical outcomes.

Conscientious objection: a global health perspective.

BMJ Glob Health

December 2024

Global Bioethics Collaborative, Los Angeles, California, USA.

Conscientious objection is a critical topic that has been sparsely discussed from a global health perspective, despite its special relevance to our inherently diverse field. In this Analysis paper, we argue that blanket prohibitions of a specific type of non-discriminatory conscientious objection are unjustified in the global health context. We begin both by introducing a nuanced account of conscience that is grounded in moral psychology and by providing an overview of discriminatory and non-discriminatory forms of objection.

Dilute Povidone-Iodine Irrigation: The Science of Molecular Iodine (I2) Kinetics and Its Antimicrobial Activity.

J Am Acad Orthop Surg

January 2025

From the UC Davis Department of Orthopaedic Surgery, Sacramento, CA.

Dilute povidone-iodine (polyvinylpyrrolidone iodine [PVP-I]) irrigation in spine surgery and total joint arthroplasty has seen a rapid and substantial increase in its use during the past decade. Yet, most surgeons do not know the chemistry and biochemistry that explain its efficacy in preventing infections. PVP-I forms a complex with molecular iodine (I2), facilitating the delivery of I2 to the membrane of the infectious organism.

Neoadjuvant therapy (NAT) has been studied in clinically localized prostate cancer (PCa) to improve the outcomes from radical prostatectomy (RP) by 'debulking' of high-risk PCa; however, using androgen deprivation therapy (ADT) at this point risks castration resistant PCa (CRPC) clonal proliferation. Our goal is to identify alternative NAT that reduce hormone sensitive PCa (HSPC) without affecting androgen receptor (AR) transcriptional activity. PCa is associated with increased expression and activation of the epidermal growth factor receptor (EGFR) family, including HER2 and ErbB3.

Bioreactor contamination monitoring using off-gassed volatile organic compounds (VOCs).

Anal Bioanal Chem

December 2024

Division of Pulmonary, Critical Care and Sleep Medicine, University of California, Davis, Sacramento, CA, USA.

Metabolically active cells emit volatile organic compounds (VOCs) that can be used in real time to non-invasively monitor the health of cell cultures. We utilized these naturally occurring VOCs in an adapted culture method to detect differences in culturing Chinese hamster ovary (CHO) cells with and without Staphylococcus epidermidis and Aspergillus fumigatus contaminations. The VOC emissions from the cell cultures were extracted and measured from the culture flask headspace using polydimethylsiloxane (PDMS)-coated Twisters, which were subjected to thermal desorption-gas chromatography-mass spectrometry (TD-GC-MS) analysis.

As demanding as dancing en pointe is, no universal standard exists to determine when a ballet dancer is ready to advance to this next level. The goal of this study was to provide preliminarily tested and reliable guidelines for a screening tool that can be used to determine (1) if a dancer is ready for pointe, (2) reasons why a dancer may not be ready, and (3) areas for improvement to guide training and preparation. Seventeen dancers aged 9 to 17 years with a minimum 4 years of ballet and who were either possibly ready for pointe or had been in pointe class less than 3 months participated in this study.
