Objective: To estimate the prevalence and economic burden of hyperkalemia in the United States (US) Medicare population. Methods: Patients were selected from a 5% random sample of Medicare beneficiaries (01 January 2010-31 December 2014) to estimate the prevalence and economic burden of hyperkalemia. The prevalence for each calendar year was calculated as the number of patients with hyperkalemia divided by the total number of eligible patients per year. ⋯ Patients with hyperkalemia incurred on average $7208 higher 30-day costs ($8894 vs. $1685) and $19,348 higher 1-year costs ($34,362 vs. $15,013) than controls (both p < .001). Among patients with CKD and/or heart failure, the 30-day and 1-year total cost differences between cohorts were $7726 ($9906 vs. $2180) and $21,577 ($41,416 vs. $19,839), respectively (both p < .001). Conclusions: Hyperkalemia had an estimated prevalence of 2.6-2.7% in the Medicare population and was associated with markedly high healthcare costs.

Breast cancer is the most frequent cancer amongst women worldwide including in Asia where the incidence rate is rapidly increasing. Even with treatment, around 30% of patients with early breast cancer progress to metastatic disease, with hormone receptor positive (HR+) and human epidermal growth factor receptor 2 negative (HER2-) breast cancer the most common phenotype. First-line endocrine therapy targeting the estrogen receptor signaling pathway provides a median progression-free survival or time to progression of 6-15 months in HR + HER2- metastatic breast cancer. ⋯ Consequently, the proportion of premenopausal women with metastatic breast cancer is higher in Asian compared with Western populations. While CDK4/6 inhibitors have been approved in the USA (FDA) since 2015, experience with them in Asia is more limited. We review the experience with the CDK4/6 inhibitor palbociclib in Asian patients with HR + HER2- metastatic breast cancer and provide guidance on the use of palbociclib in these patients.

Comparative Study
FDA Approved vs. Pharmacy Compounded 17-OHPC - Current Issues for Obstetricians to Consider in Reducing Recurrent Preterm Birth.
17α-hydroxyprogesterone caproate (17-OHPC; MAKENA and generic equivalents) is the only FDA-approved medicine available to reduce the risk of preterm birth (PTB) in pregnant women with a singleton pregnancy who have a history of singleton spontaneous PTB. The FDA held an Advisory Committee meeting in October 2019 to review conflicting data between one positive U. S.-based study and one international study that failed to confirm the benefit. ⋯ Compounded drugs may be associated with significant safety risks, as poor compounding practices have resulted in serious problems with drug quality (lack of sterility or stability) and potency. Given the markedly higher rates of PTB in the U. S. compared with other industrialized nations, it is imperative that FDA-approved, GMP-produced 17-OHPC (FDA-approved brand and generic formulations) is available while additional research on its optimal use is conducted, without providers and patients resorting to pharmacist-compounded formulations for their high-risk pregnant patients.

Objective: To determine how results from a prognostic 40-gene expression profiling (40-GEP) test would impact clinician management decisions and how their choices would align with a National Comprehensive Cancer Network (NCCN) compliant, risk-directed management plan for high-risk cutaneous squamous cell carcinoma (cSCC). Methods: Clinicians attending a national dermatology conference were presented with 40-GEP test validation data. They were asked to rate clinicopathological features and molecular test results to assess their opinion of how concerning each is to cSCC prognosis. ⋯ Specifically, there was significant reduction in the recommendations for sentinel lymph node biopsy, adjuvant radiation or chemotherapy, follow-up time, and nodal imaging. By comparison, when a 40-GEP result indicated an increased risk of metastasis (Class 2B), significant risk-appropriate increases in management intensity was observed for the aforementioned clinical decisions. Conclusion: Integration of 40-GEP results impacted management decisions in a significant and risk-appropriate manner for high-risk cSCC patient scenarios, while remaining aligned with national guidelines for patient management.

Objective: To evaluate the effect of individual lower urinary tract symptoms (LUTS) and LUTS-specific bother on daily/leisure activities, work productivity and treatment behaviors and satisfaction in a Brazilian population reporting symptoms of the overactive bladder (OAB) syndrome. Methods: Secondary analysis of Brazil LUTS study data, including individuals ≥40 years old with a possible diagnosis of OAB, based on a score of ≥8 on the OAB-V8 questionnaire. Participants used a 5-point Likert scale to rate occurrence of LUTS during the previous month. ⋯ Treatment seeking for OAB was low among men and women overall (35.1 and 43.6%, respectively), with highest rates among individuals in the 60-69 age group. Conclusions: LUTS of all categories impacted all domains studied. These results highlight the importance of comprehensive LUTS assessment in OAB patients, including voiding, storage and post-micturition symptoms.
