Article Synopsis
  • Cetuximab is a standard treatment for head and neck squamous cell carcinoma (HNSCC), but resistance can occur due to activation of certain receptor tyrosine kinases; cabozantinib is an inhibitor that shows promise in overcoming this resistance.
  • A phase I trial tested the safety and efficacy of combining cetuximab with cabozantinib in patients with recurrent/metastatic HNSCC, establishing the maximally tolerated dose of cabozantinib at 60 mg without dose-limiting toxicities.
  • The trial reported a 20% overall response rate, a 75% disease control rate, and manageable toxicity, suggesting that this treatment combination is worth further study, especially in patients who have

Purpose: Evidence suggests that oncology patients are satisfied with and sometimes prefer telemedicine compared with in-person visits; however, data are scarce on when telemedicine is appropriate for specific cancer populations. In this study, we aim to identify factors that influence patient experience and appropriateness of telemedicine use among a head and neck cancer (HNC) population.

Methods: We performed a mixed-methods study at a multisite cancer center.

Article Synopsis
  • The study investigates oncology patients' engagement in virtual mind-body therapies, especially accelerated by the COVID-19 pandemic.
  • A survey of 148 patients revealed that engagement varied, with higher participation from females, non-White individuals, and retirees, who attended an average of 4.23 classes per week.
  • The analysis identified three engagement subgroups, highlighting the interest in meditation and Tai Chi videos, suggesting the importance of providing both live and recorded programming to cater to different patient needs.

The most common cancer caused by human papillomavirus (HPV) infection in the United States is oropharyngeal cancer (OPC), and its incidence has been rising since the turn of the century. Because of substantial long-term morbidities with chemoradiation and the favorable prognosis of HPV-positive OPC, identifying the optimal deintensification strategy for this group has been a keystone of academic head-and-neck surgery, radiation oncology, and medical oncology for over the past decade. However, the first generation of randomized chemotherapy deintensification trials failed to change the standard of care, triggering concern over the feasibility of de-escalation.

Importance: Xerostomia and reduced mouth opening are negatively associated with quality of life after radiation therapy (RT) for head and neck cancer. Studies comparing objective measures of function with patient-reported outcomes (PROs) have not revealed a clear association.

Objective: To determine how much of the variation in PROs is explained by objective measures of salivary gland and oral cavity functions (salivary flow and maximal interincisal opening).

Pain and insomnia often co-occur and impair the quality of life in cancer survivors. This study evaluated the effect of acupuncture versus cognitive behavioral therapy for insomnia (CBT-I) on pain severity among cancer survivors with comorbid pain and insomnia. Using data from the CHOICE trial that compared acupuncture versus CBT-I for insomnia among cancer survivors, we analyzed the effect of interventions on pain outcomes in 70 patients with moderate to severe baseline pain.

Our understanding of human papillomavirus (HPV)-related oropharyngeal cancer (OPC) and its molecular basis continues to evolve and produce important insights into customized therapeutic strategies. Novel therapeutics exploiting HPV-related targets are being evaluated in the incurable setting, while the favorable prognosis of locoregionally advanced disease has stimulated investigation into de-escalation strategies. There is much opportunity for better personalization of standard therapy according to HPV status.

Purpose: ChemoPalRx is a novel provider order entry mobile application for chemotherapy. This study aims to evaluate the accuracy of prescribing chemotherapy using ChemoPalRx versus handwritten orders at a safety-net hospital in Los Angeles.

Methods: In a cross-sectional study from October 2019 to December 2019, we evaluated all outpatient chemotherapy orders for accuracy.

Obesity is best understood as a multifactorial metabolic imbalances disorder. In a cross-sectional study, we aimed to explore sociodemographic and dietary determinants of obesity in relation to brain-gut homeostasis among overweight and obese individuals. Multivariate logistic regression models were used to examine obesity and its association with sociodemographic and dietary factors.

Objective: In response to the national opioid crisis, governmental and medical organizations have called for broader insurance coverage of acupuncture to improve access to nonpharmacologic pain therapies, especially in cancer populations, where undertreatment of pain is prevalent. We evaluated whether cancer patients would be willing to use insurance-covered acupuncture for pain.

Design And Setting: We conducted a cross-sectional survey of cancer patients with pain at one academic center and 11 community hospitals.

Droplet-based microfluidic techniques can form and process micrometer scale droplets at thousands per second. Each droplet can house an individual biochemical reaction, allowing millions of reactions to be performed in minutes with small amounts of total reagent. This versatile approach has been used for engineering enzymes, quantifying concentrations of DNA in solution, and screening protein crystallization conditions.

Necrotizing fasciitis is a life-threatening soft tissue infection that results in rapid local tissue destruction. Type 1 necrotizing fasciitis is characterized by polymicrobial, synergistic infections that are caused by non-Group A streptococci, aerobic and anaerobic organisms. Type 2 necrotizing fasciitis involves Group A Streptococcus (GAS) with or without a coexisting staphylococcal infection.

Adding reagents to drops is one of the most important functions in droplet-based microfluidic systems; however, a robust technique to accomplish this does not exist. Here, we introduce the picoinjector, a robust device to add controlled volumes of reagent using electro-microfluidics at kilohertz rates. It can also perform multiple injections for serial and combinatorial additions.

Among mutations in human Runx1/AML1 transcription factors, the t(8;21)(q22;q22) genomic translocation that creates an AML1-ETO fusion protein is implicated in etiology of the acute myeloid leukemia. To identify genes and components associated with this oncogene we used Drosophila as a genetic model. Expression of AML1-ETO caused an expansion of hematopoietic precursors in Drosophila, which expressed high levels of reactive oxygen species (ROS).

Using a large consortium of undergraduate students in an organized program at the University of California, Los Angeles (UCLA), we have undertaken a functional genomic screen in the Drosophila eye. In addition to the educational value of discovery-based learning, this article presents the first comprehensive genomewide analysis of essential genes involved in eye development. The data reveal the surprising result that the X chromosome has almost twice the frequency of essential genes involved in eye development as that found on the autosomes.

Purpose Of Review: This review assesses the relative effect of fat versus carbohydrate and the differences between fatty acids and types of carbohydrate on insulin resistance and associated risk factors for diabetes and cardiovascular disease.

Recent Findings: The debate continues over whether high-carbohydrate or high-fat diets have the more deleterious metabolic effects. Large randomized controlled trials have shown that a reduction of fat intake as part of a healthy lifestyle combined with weight reduction and exercise reduce the risk of type 2 diabetes.
