Stem Cell Origin of Cancer: Clinical Implications beyond Immunotherapy for Drug versus Therapy Development in Cancer Care.

Although immunotherapy has revolutionized cancer care, there is still an urgent need to enhance its efficacy and ensure its safety. A correct cancer theory and proper scientific method empower pertinent cancer research and enable effective and efficient drug versus therapy development for patient care. In this perspective, we revisit the concept of immune privilege in a cancer cell versus normal cell, as well as in a cancer stem cell versus normal stem cell.

Molecular Simulations of Hydrogen Sorption in Semicrystalline High-Density Polyethylene: The Impact of the Surface Fraction of Tie-Chains.

The modeling of the barrier properties of semicrystalline polymers has gained interest following the possible application of such materials as protective liners for the safe supply of pressurized hydrogen. The mass transport in such systems is intimately related to the complex intercalation between the crystal and amorphous phases, which was approached in this work through an all-atom representation of high-density polyethylene structures with a tailored fraction of amorphous-crystalline connections (tie-chains). Simulations of the polymer pressure-volume-temperature data and hydrogen sorption were performed by means of molecular dynamics and the Widom test particle insertion method.

Erythrocyte PIG-A mutant frequencies in cancer patients receiving cisplatin.

Background: Cisplatin is a primary chemotherapy choice for various solid tumors. DNA damage caused by cisplatin results in apoptosis of tumor cells. Cisplatin-induced DNA damage, however, may also result in mutations in normal cells and the initiation of secondary malignancies.

An advanced molecular medicine case report of a rare human tumor using genomics, pathomics, and radiomics.

Pulmonary Sclerosing Pneumocytoma (PSP) is a rare tumor of the lung with a low malignant potential that primarily affects females. Initial studies of PSP focused primarily on analyzing features uncovered using conventional X-ray or CT imaging. In recent years, because of the widespread use of next-generation sequencing (NGS), the study of PSP at the molecular-level has emerged.

Supporting the Health and Well-Being of Indigenous Communities: A Position Paper From the American College of Physicians.

Indigenous peoples in the United States experience many health disparities and barriers to accessing health care services. In addition, Indigenous communities experience poor social drivers of health, including disproportionately high rates of food insecurity, violence, and poverty, among others. These challenges are unsurprising, given historical societal discrimination toward Indigenous peoples and government policies of violence, forced relocation with loss of ancestral home, and erasure of cultures and traditions.

Stem Cell Theory of Cancer: Implications for Translational Research from Bedside to Bench.

A stem cell theory of cancer considers genetic makeup in the proper cellular context. It is a unified theory of cancer that unites the genome with the epigenome, links the intracellular with the extracellular, and connects the cellular constituents and compartments with the microenvironment. Although it allies with genomic medicine, it is better aligned with integrated medicine.

Long-Term Services and Supports for Older Adults: A Position Paper From the American College of Physicians.

The number of Americans aged 65 years or older is expected to increase in the coming decades. Because the risk for disability increases with age, more persons will need long-term services and supports (LTSS) to help with bathing, eating, dressing, and other everyday tasks. Long-term services and supports are delivered in nursing homes, assisted living facilities, the person's home, and other settings.

Strengthening Food and Nutrition Security to Promote Public Health in the United States: A Position Paper From the American College of Physicians.

Food insecurity functions as a social driver of health, directly negatively impacting health status and outcomes, which can further negatively impact employment and income and increase medical expenditures-all of which exacerbates food insecurity. Progress in meaningfully reducing the food-insecurity rate has stalled in recent years. Although rates have decreased since their peak during the Great Recession, these gains have been reversed by the economic implications of the COVID-19 pandemic.

Health Care for Our Nation's Veterans: A Policy Paper From the American College of Physicians.

The Veterans Health Administration (VHA) is the United States' largest integrated health care delivery system, serving over 9 million enrollees at nearly 1300 health care facilities. In addition to providing health care to the nation's military veterans, the VHA has a research and development program, trains thousands of medical residents and other health care professionals, and conducts emergency preparedness and response activities. The VHA has been celebrated for delivering high-quality care to veterans, early adoption of electronic medical records, and high patient satisfaction.

Financial Profit in Medicine: A Position Paper From the American College of Physicians.

The steady growth of corporate interest and influence in the health care sector over the past few decades has created a more business-oriented health care system in the United States, helping to spur for-profit and private equity investment. Proponents say that this trend makes the health care system more efficient, encourages innovation, and provides financial stability to ensure access and improve care. Critics counter that such moves favor profit over care and erode the patient-physician relationship.

A Case of Metastatic Pancreatic Adenocarcinoma in Complete Remission Using Chemotherapy and Immunotherapy.

Among the various types of cancer, pancreatic cancer is considered to have a particularly grim prognosis. Treatment includes surgery, chemotherapy, or both. While the role of immunotherapy is well-studied in many types of cancer, such is not the case with pancreatic cancer.

Nanoparticle albumin-bound paclitaxel with cetuximab and carboplatin as first-line therapy for recurrent or metastatic head and neck cancer: A single-arm, multicenter, phase 2 trial.

Objectives: Macropinocytosis promotes internalization of albumin into cells to serve as a nutrient supply and is constitutively driven by signaling pathways frequently hyperactivated in head and neck squamous-cell carcinoma (HNSCC). In this way, drugs bound to albumin may selectively target HNSCC. nab-paclitaxel is a nanoparticle albumin-bound formulation of paclitaxel that improves drug delivery into tumor compared to paclitaxel.

A Comprehensive Policy Framework to Understand and Address Disparities and Discrimination in Health and Health Care: A Policy Paper From the American College of Physicians.

Racial and ethnic minority populations in the United States experience disparities in their health and health care that arise from a combination of interacting factors, including racism and discrimination, social drivers of health, health care access and quality, individual behavior, and biology. To ameliorate these disparities, the American College of Physicians (ACP) proposes a comprehensive policy framework that recognizes and confronts the many elements of U.S.

Pembrolizumab-Induced Cold Agglutinin Disease.

BACKGROUND The introduction of immunotherapy in the management of metastatic lung cancer appears to be changing their natural history. Most patients tolerate immunotherapy without any significant adverse events. Nevertheless, a significant number of patients still experience adverse effects.

Racism and Health in the United States: A Policy Statement From the American College of Physicians.

Racial minorities in the United States have reported experiencing widespread racism throughout all aspects of life, from housing to education to employment. Existing research has examined the role of racism, discrimination, and violence in one's interaction with the health care system and their association with poorer mental and physical health. Systemic racism that underlies the fabric of society often manifests itself in prominent institutions, such as law enforcement agencies, regardless of individual intent.

An assessment of Oxford Nanopore sequencing for human gut metagenome profiling: A pilot study of head and neck cancer patients.

Gut metagenome profiling using the Oxford Nanopore Technologies (ONT) sequencer was assessed in a pilot-sized study of 10 subjects. The taxonomic abundance of gut microbiota derived from ONT was comparable with Illumina Technology (IT) for the high-abundance species. IT better detected low-abundance species through amplification, when material was limited.

A Unique Case of Severe Anemia Secondary to Copper Deficiency in an Adult Patient.

Anemia is a frequently encountered problem in the healthcare system. Common causes of anemia include blood loss, followed by impaired red blood cell production and red blood cell destruction. This case demonstrates the need for cognizance of the less frequent causes of anemia.

The Role of Immunotherapy and Radiation Therapy in Tumor Chemosensitivity in Advanced Head and Neck Cancer.

BACKGROUND Cancer is the second leading cause of death internationally, resulting in millions of deaths each year. While treatment in the past has heavily relied on surgery and radiotherapy, chemotherapy and immunotherapy are being increasingly utilized depending on disease presentation. CASE REPORT A 56-year-old male presented to the Emergency Department with a 3-week history of a rapidly enlarging left supraclavicular neck mass.

An assessment of benefits and harms of hepatocellular carcinoma surveillance in patients with cirrhosis.

Unlabelled: Although surveillance ultrasound and alpha fetoprotein (AFP) tests have minimal direct harm, downstream harms from follow-up tests must be weighed against surveillance benefits when determining the value of hepatocellular carcinoma (HCC) screening programs. Our study's aims were to characterize prevalence and correlates of surveillance benefits and harms in cirrhosis patients undergoing HCC surveillance. We conducted a retrospective cohort study among patients with cirrhosis followed at a safety-net health system between July 2010 and July 2013.

Efficacy and safety of endoscopic gallbladder drainage in acute cholecystitis: Is it better than percutaneous gallbladder drainage?

Background And Aims: The efficacy and safety of endoscopic gallbladder drainage (EGBD) performed via endoscopic retrograde cholangiography (ERC)-based transpapillary stenting or EUS-based transmural stenting are unknown. We aimed to conduct a proportion meta-analysis to evaluate the cumulative efficacy and safety of these procedures and to compare them with percutaneous gallbladder drainage (PGBD).

Methods: We searched several databases from inception through December 10, 2015 to identify studies (with 10 or more patients) reporting technical success and postprocedure adverse events of EGBD.

Drug-induced fatty liver disease: An overview of pathogenesis and management.

Over the past decades, many drugs have been identified, that can potentially induce steatohepatitis in the predisposed individual. Classically this has been incriminated to amiodarone, perhexiline, and 4,4'-diethylaminoethoxyhexestrol (DH), all of which have been found to independently induce the histologic picture of non-alcoholic steatohepatitis (NASH). Pathogenetic mechanisms of hepatotoxicity although still evolving, demonstrate that mitochondrial dysfunction, deranged ATP production and fatty acid catabolism likely play an important role.
