RESUMEN

Online resources such as YouTube® can serve as the go-to resource for patients and their caregivers after a life-changing diagnosis of pancreatic cancer. There is a need to analyze the content and educational value of these videos for patients with pancreatic cancer. The top 100 most viewed videos on pancreatic cancer on YouTube® were assessed and data were collected on various variables such as views, likes, dislikes, and comments. Videos categorized as patient educational videos were further analyzed for their content, source, and educational value. Videos uploaded by patients were the most discussed (p = 0.014) and liked (p = 0.0028) videos on YouTube®. The content of the videos (personal experience, advertisement, patient education, medical professional education, alternative treatments, and increased pancreatic cancer awareness) varied depending on the uploader (patients, healthcare providers, professional societies, media) of the videos (p = 0.0007). Patient education videos were poor in being comprehensive on their education of pancreatic cancer based on our rubric (mean score of 7.67 ± 2.63 of 20 possible points). The current study shows that the educational values of YouTube® videos related to pancreatic cancer remain limited. There is significant room for healthcare providers to use the platform to develop and share comprehensive videos that can be used as more effective sources of patient education.

RESUMEN

INTRODUCTION: Despite several therapeutic advancements, the proportion of patients with advanced biliary tract cancers (BTC) surviving 5 years from diagnosis remains dismal. The increasing recognition of targetable genetic alterations in BTCs has ushered in a new era in the treatment of these patients. Newer therapeutic agents targeting mutations such as isocitrate dehydrogenase (IDH), fibroblastic growth factor receptor (FGFR), human epidermal growth factor receptor (HER), and so on have established a new standard of care for treatment upon progression on frontline therapy in patients with disease harboring these mutations. AREAS COVERED: The current review aims to concisely summarize progress with various targeted therapy options for BTC. We also briefly discuss future directions in clinical and translational research for the adoption of a personalized approach for the treatment of unresectable or advanced BTC. EXPERT OPINION: Several new agents continue to emerge as feasible treatment options for patients with advanced BTC harboring targetable mutations. There is a growing need to identify mechanisms to conquer primary and acquired resistance to these agents. The identification of potential biomarkers that predict response to targeted therapy may be helpful in adopting a more tailored approach. All patients receiving treatment for advanced BTC should undergo tissue genomic profiling at diagnosis.

RESUMEN

ABSTRACT: Venous thromboembolic events are significant contributors to morbidity and mortality in patients with stroke. Neutrophils are among the first cells in the blood to respond to stroke and are known to promote deep vein thrombosis (DVT). Integrin α9 is a transmembrane glycoprotein highly expressed on neutrophils and stabilizes neutrophil adhesion to activated endothelium via vascular cell adhesion molecule 1 (VCAM-1). Nevertheless, the causative role of neutrophil integrin α9 in poststroke DVT remains unknown. Here, we found higher neutrophil integrin α9 and plasma VCAM-1 levels in humans and mice with stroke. Using mice with embolic stroke, we observed enhanced DVT severity in a novel model of poststroke DVT. Neutrophil-specific integrin α9-deficient mice (α9fl/flMrp8Cre+/-) exhibited a significant reduction in poststroke DVT severity along with decreased neutrophils and citrullinated histone H3 in thrombi. Unbiased transcriptomics indicated that α9/VCAM-1 interactions induced pathways related to neutrophil inflammation, exocytosis, NF-κB signaling, and chemotaxis. Mechanistic studies revealed that integrin α9/VCAM-1 interactions mediate neutrophil adhesion at the venous shear rate, promote neutrophil hyperactivation, increase phosphorylation of extracellular signal-regulated kinase, and induce endothelial cell apoptosis. Using pharmacogenomic profiling, virtual screening, and in vitro assays, we identified macitentan as a potent inhibitor of integrin α9/VCAM-1 interactions and neutrophil adhesion to activated endothelial cells. Macitentan reduced DVT severity in control mice with and without stroke, but not in α9fl/flMrp8Cre+/- mice, suggesting that macitentan improves DVT outcomes by inhibiting neutrophil integrin α9. Collectively, we uncovered a previously unrecognized and critical pathway involving the α9/VCAM-1 axis in neutrophil hyperactivation and DVT.

RESUMEN

Chronic myeloproliferative neoplasms (MPN) include polycythemia vera (PV), primary myelofibrosis, essential thrombocythemia (ET) and chronic myeloid leukemia (CML). Overlapping MPNs are rare; however, they can occur in the same individual. The present case report describes a patient with both triple-negative ET and CML. A 64-year-old woman was followed-up at our hematology clinic at Feist Weiller Cancer Center, Louisiana State University Health Shreveport (Shreveport, LA, USA) since 2000 after she was diagnosed with JAK2V617F-negative ET. The patient remained stable on hydroxyurea until 2012, when they underwent a bone marrow biopsy for progressively increasing white blood cell counts, and the pathology was consistent with CML; PCR for BCR-ABL was positive for both P210 and P190 transcripts. The patient was then initiated on dasatinib. After dasatinib, they were given a trial of imatinib, and were later transitioned to nilotinib and finally to bosutinib (2019) due to unchanged thrombocytosis. Next-generation sequencing from a bone marrow biopsy in 2019 demonstrated an EZH2 mutation that may be associated with triple-negative ET. CML was in major molecular response at that time. The patient was continued on bosutinib with hydroxyurea, after which hydroxyurea was changed to anagrelide due to worsening anemia and persistent thrombocytosis. However, bosutinib and anagrelide were discontinued due to worsening pulmonary hypertension. The patient was noted to have peripheral blasts of 14% by flow cytometry, after which they underwent a repeat bone marrow biopsy in 2022, which showed extensive myelofibrosis. BCR-ABL transcripts were undetectable. Given their accelerated myelofibrosis, the patient was started on a hypomethylating agent, decitabine/cedazuridine, along with darbepoetin for anemia in June 2022. Given their persistent thrombocytosis, the patient was also started on peginterferon α. Most studies reporting two clonal processes in the same patient have been for PV and CML. To the best of our knowledge, this is the first reported case of triple-negative ET with double transcript CML in the same individual.

RESUMEN

This case report presents a rare and challenging manifestation of polyostotic fibrous dysplasia (FD), a skeletal developmental anomaly characterized by the proliferation of fibrous connective tissue intermingled with irregular bony trabeculae. While monostotic FD is more common, polyostotic FD can occur in the context of McCune-Albright syndrome, a multisystem developmental disorder. Our patient, a 55-year-old female with a history of diabetes, hypothyroidism, and dyslipidemia, presented with progressively worsening dysphagia, sternal pain, and swelling over three years. Clinical examination revealed a tender and hard swelling in the upper sternal area, prompting further evaluation. Laboratory results, including bone turnover markers, were unremarkable. Imaging studies unveiled a sizable anterior mediastinal lesion with heterogeneous enhancement and coarse calcifications, initially raising concerns of malignancy. Subsequent positron emission tomography scan findings confirmed FD involvement in both the sternum and right femur. Histopathology of the mediastinal mass revealed a spindle cell neoplasm with bony metaplasia, consistent with FD, supported by immunohistochemistry. A multidisciplinary team affirmed the diagnosis of polyostotic FD, and follow-up imaging after one year demonstrated no significant change in lesion size, confirming a benign etiology. While bisphosphonate therapy was planned, regrettably, the patient was lost to follow-up. This case underscores the importance of a comprehensive, multidisciplinary approach in diagnosing and managing complex presentations of FD, ultimately contributing to improved patient care and outcomes in such instances.

RESUMEN

INTRODUCTION: Colorectal cancer (CRC) is the second leading cause of cancer-related deaths in the United States (US), however racial disparities in outcomes persist. We sought to assess the correlation of availability of primary care physicians (PCPs) and racial disparities in CRC-related mortality. METHODS: We studied the correlation between age-adjusted incidence and mortality rates of CRC among all 50 states and the District of Columbia (D.C.) from the Center for Disease Control (CDC) Wide-Ranging Online Data for Epidemiologic Research (WONDER) with the number of actively practicing PCPs in all 50 states and D.C. from the Association of American Medical Colleges (AAMC) State Physician Workforce Data Report. Pearson's coefficient was used to study correlations and the two-sample t test was used for comparing state-level PCP/CRC ratios between the two groups. Statistical analysis was performed using VassarStats. RESULTS: The mean AAMR per 100,000 population for CRC was significantly higher among AA versus White populations (t = 5.79, p < 0.001). Higher state-wide PCP per CRC case ratio correlated with lower state-wide CRCrelated mortality (r = -0.36, p = 0.011). The mean PCP per CRC case ratio was significantly lower among AA compared to White populations (t = -15.95, p < 0.0001). Higher PCP per CRC case ratio correlated with lower CRC-related mortality among both White (r = -0.64, p < 0.0001) and AA (r = -0.57, p = 0.0002) populations. CONCLUSIONS: These findings suggest that racial disparities in CRC-related mortality may at least in part be related to lower availability of PCPs. Efforts focused on the development of strategies focused on improving access to primary care may help bridge racial disparities in CRC-related outcomes.

RESUMEN

Colorectal cancer is the second leading cause of cancer-related death in the United States, with a rising incidence, especially in young adults. Care for patients with colorectal cancer is associated with significant healthcare costs and expenditures. We retrospectively interrogated the National Inpatient Sample for admissions in patients with colorectal cancer from 2007 to 2017. A total of 1,962,705 admissions were identified: 50.2% were men, 64.4% were white, and the median age was 68. Most admissions (47.8%) that were coded for anatomical location of malignancy were for ascending colon cancer. The average in-hospital mortality was 4.9%, with a lower mortality in admissions with ascending colon cancer (2.9, P < 0.001). The median length of stay was 5 days, with a longer stay in admissions with transverse colon cancer (9 days, P < 0.0001). The median cost of hospitalization was $12,295 and was significantly higher for patients with descending colon malignancy ($16,369, P < 0.0001). The number of annual hospitalizations stayed steady overall but increased by 98.6% for rectosigmoid cancer. Our findings highlight the high costs of hospitalization and the overall economic burden associated with inpatient admissions among patients with colorectal cancer.

RESUMEN

Background: The novel corona virus has changed the way individuals interact with each other and society. In the medical sector, this has affected the residents and fellows who spend the majority of their time on the front lines. Methods: We conducted a cross-sectional survey to assess the impact of the COVID-19 pandemic on the lives and training of house-staff across the USA. Respondents in our survey reported feeling significantly overwhelmed by the ongoing pandemic. Results: The majority of house-staff were significantly concerned about the lack of protective equipment, inability to safeguard themselves from infection and inability to look after their families. Concerns regarding contracting the infection and transmitting it to their loved ones were reported as a cause of mental distress among resident physicians. Increasing patient load, lack of protective equipment, and disruption of educational and academic activities during the COVID-19 pandemic have all reportedly affected the training and overall well-being of resident physicians. Conslusion: Our study adds further support for measures to safeguard house-staff with proper protective equipment and ensure adequate support for both mental and physical well-being during these challenging times.

RESUMEN

INTRODUCTION: Over the last few years, improved outcomes in patients with chronic lymphocytic leukemia (CLL) have been credited to the introduction of novel agents for its treatment. However, the overall cardiovascular safety profile of these agents has not been studied adequately. METHODS: We searched the Food and Drug Administration Adverse Event Reporting System (FAERS) database for adverse events reported for several of these novel agents: ibrutinib, acalabrutinib, venetoclax, and idelalisib. RESULTS: A total of 6074 cardiac adverse events were identified; ibrutinib (4832/36581; 13.2%) was found to have the highest risk of cardiac adverse events. The frequency of atrial fibrillation was highest (41.5%) in the ibrutinib group, while the idelalisib and acalabrutinib groups had the highest reported frequencies of heart failure (25.1%) and myocardial infarction (13.6%), respectively. Hypertension was noted to be relatively higher in the acalabrutinib (25.6%) and venetoclax (11.8%) groups. Overall reported mortality associated with cardiac events was highest in the venetoclax (29.4%) and idelalisib (27.1%) groups. CONCLUSION: Novel agents in the CLL armamentarium have been associated with several cardiovascular adverse events. Further studies are needed to identify high-risk groups that would benefit from robust cardiovascular surveillance after initiation of treatment with these novel agents.
