    Abstract Opinion statement: Inflammatory breast cancer (IBC) is a rare but aggressive subtype of breast cancer that has a propensity for locoregional recurrence and distant metastasis and is associated with a disproportionately high percentage of breast cancer deaths. IBC is not resectable at initial diagnosis and trimodality therapy is considered the standard treatment for IBC. This includes systemic therapy upfront, followed by modified radical mastectomy and comprehensive chest wall and regional node radiation. Despite this aggressive multi-modal treatment strategy, the prognosis remains worse in IBC when compared with non-inflammatory locally advanced breast cancers. For patients presenting with de novo stage IV IBC, treatment recommendations vary depending on tumor burden, cancer subtype, and presence of comorbidities. Efforts to improve outcomes in IBC are currently underway; however, progress has been affected by the low incidence of disease and limited number of dedicated studies in this population. Improvements in systemic therapies in breast cancer in general are likely to lead to improvements in IBC as well. More dedicated trials are needed to identify additional treatment strategies that may help to improve prognosis for these patients. Additionally, better frameworks for diagnosis, risk stratification based upon factors such as molecular subtype and response to neoadjuvant therapy, will be important to make further progress in IBC.

    Abstract Objective: To assess the incidence of vascular events in patients with head and neck cancer.
    Review methods: Primary studies identified through April 2023. Meta-analysis was performed.
    Results: There were 146 studies included in the systematic review. Rates of events were collected in the overall group, those with chemoprophylaxis, and those that underwent surgery, radiation, or chemotherapy. Of 1 184 160 patients, 4.3% had a vascular event. Radiation therapy had highest risk of overall events and stroke when compared to surgery and chemotherapy. Chemotherapy had a higher risk of stroke and overall events when compared to surgery.
    Conclusions: Vascular events occur in 4%-5% of patients with head and neck cancer. Our data does not support the use of routine anticoagulation. Patients undergoing radiation therapy had the highest frequency of events.

    Abstract During the past three decades, the ability of guanidinium arenesulfonate host frameworks to encapsulate a wide range of guests has been amply demonstrated, with more than 700 inclusion compounds realized. Herein, we report crystalline inclusion compounds based on a new aliphatic host, guanidinium cyclohexanemonosulfonate, which surprisingly exhibits four heretofore unobserved architectures, as described by the projection topologies of the organosulfonate residues above and below hydrogen-bonded guanidinium sulfonate sheets. The inclusion compounds adopt a layer motif of guanidinium sulfonate sheets interleaved with guest molecules, resembling a mille-feuille pastry. The aliphatic character of this remarkably simple host, combined with access to greater architectural diversity and adaptability, enables the host framework to accommodate a wide range of guests and promises to expand the utility of guanidinium organosulfonate hosts.

    Abstract An 11-y-old hembra alpaca was admitted because of cerebellar and vestibular signs, dysphagia, and aspiration pneumonia; without clinical improvement following empirical therapy, the patient was euthanized. On autopsy, a neoplasm was found incorporating the right vestibulocochlear nerve at the level of the acoustic meatus. Histologically, the mass was composed of a multiphasic primitive cell population associated with a dense fibrous stroma and enveloping a remnant ganglion and nerve bundles. Patterns included dense ribbons and cords of embryonal neuroepithelial cells admixed with loosely defined interlacing spindle cells. The embryonal cells had angular cell profiles with variable amounts of lightly basophilic cytoplasm, ovoid-to-irregular nuclei, and an open chromatin pattern with a typically inapparent nucleolus. Necrosis was not evident, and there was 1 mitotic figure per 2.37 mm

    Abstract Background and objectives: The Centers for Medicare & Medicaid Services implemented federal requirements on January 1, 2021, under the Public Health Service Act that require hospitals to provide a list of payer-negotiated prices or "standard charges" in a machine-readable file and in a patient-friendly online estimator for standard services. We sought to assess compliance by United States hospitals associated with neurosurgical training programs with these federal requirements for 11 common neurosurgical procedures.
    Methods: We performed a cross-sectional analysis in March 2023 of 116 United States hospitals associated with a neurosurgical training program to assess compliance with the new federal requirements to have a machine-readable, downloadable file with standard charges and a patient-friendly online estimator for two spinal procedures.
    Results: A total of 110/114 (96.5%) hospitals were compliant with the requirement for a machine-readable file with payer-negotiated prices. A total of 47/110 hospitals (42.7%) were compliant with downloadable machine-readable files and reported at least one payer-negotiated price for 1 of the 11 common neurosurgical procedures. A total of 45/110 (40.9%) used bundled Diagnosis-Related Group codes, and 18/110 (16.4%) did not contain any price information for neurosurgical procedures. For neurosurgical procedures, the percent difference between the average negotiated private insurance and Medicare price per procedure ranged from 17.5% to 77.6%. Medicare and private insurance data for each procedure were available on average for 10.3 states (SD = 3.8) and 15.6 states (SD = 4.8), respectively.
    Conclusion: While hospital compliance with federal requirements for machine-readable files with payer-negotiated prices was high, availability of payer-negotiated prices for 4 major insurance types across 11 common neurosurgical procedures based on Current Procedural Terminology codes was sparce. Consequently, meaningful conclusions on procedure-related charges for elective procedures are difficult for patients to make because of the unintelligible format of data and a lack of reporting of charges per Current Procedural Terminology code in a comprehensive manner.

Necrosis was not evident, and there was 1 mitotic figure per 2.37 mm². The entire mass was infiltrated by small numbers of lymphocytes and plasma cells. Immunohistochemistry (IHC) revealed strong and diffuse cytoplasmic immunolabeling for vimentin, microtubule-associated protein-2, protein gene product 9.5, and synaptophysin; ~50% immunolabeling for cytokeratin AE1/3; sporadic OLIG2 and S100 immunolabeling; and absent glial fibrillary acidic protein immunolabeling. Based on the histologic pattern and the IHC results, our diagnosis was a poorly differentiated embryonal tumor with ependymal differentiation associated with the vestibulocochlear nerve.

    Abstract Ancillary services, such as spinning reserves, can provide grid reliability and contribute to profitability of an energy resource. We exercise an existing dispatch optimization model to estimate the profitability of a concentrating solar power plant by incorporating the sale of spinning reserves in the ancillary service market using the National Renewable Energy Laboratory’s System Advisor Model to simulate operations within a 72-h rolling horizon framework. Assuming a price-taker approach with day-ahead energy and spinning reserve prices from both the California Independent System Operator and the Electricity Reliability Council of Texas, we find that selling spinning reserves in addition to electric energy increases plant profitability by up to 7% with perfect knowledge of day-ahead pricing and solar resource availability. This finding suggests that spinning reserve markets provide significant value streams to concentrating solar power plants that can leverage thermal energy storage to offer reliable production in the short-to-medium term.

    Abstract Since 2016, the United States has experienced a resurgence in the number of hepatitis A virus (HAV) cases and outbreaks. These outbreaks have been sustained by person-to-person transmission with cases occurring predominantly in high-risk populations including intravenous drug users, individuals experiencing homelessness, and men who have sex with men. To investigate HAV transmission, a molecular-surveillance system consisting of real-time RT-PCR (rRT-PCR) for detection, and a conventional RT-PCR assay for genotyping of HAV, was established in New York State (NYS) in 2019. Since then, a total of 271 HAV-positive serum samples collected from cases across NYS between 2019 and 2021 were identified by rRT-PCR. To rapidly and efficiently generate HAV whole-genome sequences, a custom AmpliSeq™ panel was designed in collaboration with Thermo Fisher. To streamline the process, sample preparation was performed on an Ion Chef and sequencing on an Ion S5XL. Of the 271 HAV-positive samples, the whole-genome sequencing (WGS) assay successfully generated 134 near-complete, high-quality HAV sequences. Phylogenetic analysis of the VP1-2A region identified 216 IB, 48 IA, and 2 IIIA genotypes, while 5 were unable to be typed due to poor sequence in this key region. The HAV whole-genome sequencing approach provided a more efficient and streamlined approach for genotyping HAV compared to previous methods and resulted in phylogenetic trees with enhanced resolution compared to the HAV VP1-2A region alone.

    Abstract In patients receiving treatment for head and neck cancer (HNC), there is a correlation between quality of life (QoL) scores and treatment outcomes. Higher QoL scores have been associated with improved survival. Despite this, the assessment of QoL in clinical trials varies considerably. Three databases (Scopus, PubMed, and Cinahl) were queried for articles published in English between 2006 and 2022. Two reviewers (SRS and ANT) performed study screening, data extraction, and risk of bias assessment. The authors identified 21 articles that met the inclusion criteria. A total of 5961 patients were evaluated. QoL was reported as average scores for specific variables across five different surveys in 12 included articles. Supplemental QoL data were available in 10 included studies. Critical appraisal of studies indicated a high risk of bias due to the inclusion of trials. There is no standard method for reporting QoL data in clinical trials for HNC patients undergoing treatment with anti-EGFR inhibitors. Future clinical trials should standardize their method for assessing and reporting quality-of-life data to increase patient-centered care and refine treatment choices to optimize survival.
