Management of Clostridioides difficile infection: Diagnosis, Treatment, and Future Perspectives.
Clostridioides difficile infection is the most common healthcare-associated infection in the United States, with potential life-threatening complications and a significant impact on the costs of care. Antibiotic stewardship as well as discontinuation of chronic acid suppressive therapy are key for its prevention and treatment. Effective infection management requires appropriate interpretation of diagnostic tests, as well as the use of vancomycin and fidaxomicin as first-line treatment. Novel treatments such as Bezlotoxumab, fecal microbiota transplant, and live biotherapeutic products are proven effective in recurrent C. difficile infection and address dysbiosis.

Fever of unknown origin and inflammation of unknown origin are highly challenging diagnostic conditions. The current practice for evaluating patients is to conduct a positron emission tomography-computed tomography (PET-CT) scan as either a first- or a second-line modality. We aimed to assess the contributory effect of PET-CT to the diagnosis and compare it with the contributory effect of CT alone. ⋯ PET-CT has a contributory effect of 75% for the diagnosis of fever of unknown origin and inflammation of unknown origin. PET-CT had superior sensitivity and inferior specificity vs the CT scan.

Calculated Medicine: Seven Decades of Accelerating Growth.
The field of Calculated Medicine has grown substantially over the last 7 decades. Comprised of objective, evidence-based medical decision tools, Calculated Medicine has broad application in medical practice, medical research, and health care management. This article reviews the history and varied methodologies of Calculated Medicine, starting with the 1953 Apgar score and concluding with a look into modern computational tools of the field: machine learning, natural language processing, artificial intelligence, and in silico research techniques. ⋯ Using natural language processing, we examine and analyze this burgeoning database. Lastly, we examine an important new direction of Calculated Medicine: self-reflection on its potential effect on racial and ethnic disparities in health care. Our field is making great strides promoting health care egality, and some of the most prominent contributions will be reviewed.

Primary care in the United States is undergoing bursts of evolution in response to health system stresses, changing demographics, and expansion of risk and value-based reimbursement structures. The impact of primary care remains substantive and associated with improved population health. ⋯ Evolutionary bursts yield new traits and in primary care, they are spawning new care models with significant implications for general internal medicine, internal medicine/pediatrics trained individuals and medicine subspecialties given the focus of these models on Medicare Advantage. Ultimately, changes in reimbursement and creative incentives will be two factors among many that will solidify the next stage of primary care in the United States.
