Objective: To estimate the avoided costs associated with reductions in end-stage kidney disease (ESKD), certain CV events (non-fatal myocardial infarction [MI], non-fatal stroke, hospitalization for heart failure [HHF]), and renal and CV death for patients treated with canagliflozin versus placebo, based on CREDENCE trial results. Methods: Renal (including ESKD) and CV events averted, based on the differences in adjusted rates of events between the canagliflozin and placebo arms in CREDENCE, were projected to the proportion of the members of a managed care organization (MCO) fitting the inclusion criteria in CREDENCE (i.e. diabetic nephropathy, at least 30 years old). The number of events averted for the population was multiplied by the unit-cost of the event, extracted from a targeted literature review, to obtain costs avoided per member per year (PMPY). ⋯ Costs avoided PMPY were $0.54 (-$0.28-$1.16) for non-fatal MI, $0.30 (-$0.22-$0.65) for non-fatal stroke, $1.56 ($0.80-$2.11) for HHF, $0.06 ($0.05-$0.07) for renal death, and $0.51 ($0.00-$0.91) for CV death. For non-fatal MI and non-fatal stroke, the lower bound of the range is interpreted as an incremental cost. Conclusions: Positive costs avoided for each of the outcomes considered were predicted in the main analysis, with ESKD as the outcome predicted to have the greatest costs avoided at $2.92 PMPY.

Observational Study
Reasons for discontinuation of novel oral anticoagulant therapy in patients with atrial fibrillation.
Aims: We sought to investigate the reasons for, and rates of, novel oral anticoagulant (DOAC) therapy discontinuation. Methods: This was an observational cohort study of patients with atrial fibrillation (AF) referred to a regional DOAC outpatient clinic between February 2013 and October 2017. The study population consisted of 875 consecutive patients with AF who visited the DOAC outpatient unit to initiate treatment with apixaban (N = 303), dabigatran (N = 267) or rivaroxaban (N = 305) for long-term ischemic stroke prophylaxis. ⋯ Limitation: This was a retrospective and non-randomized study, and our results should be interpreted in light of these observations. Conclusion: DOAC discontinuation rates varied significantly and appeared related to drug-specific side effects, patient-initiated discontinuation and bleeding. We observed longer-term administration of apixaban, suggesting that this drug is better tolerated than dabigatran or rivaroxaban.

Background: Blood purification therapy has not been applied in the detoxification of germanium compounds. This report described a case of germanium poisoning with renal failure, liver dysfunction, and acute pancreatitis which was successfully treated by continuous venovenous hemodiafiltration (CVVHDF) combined with plasmapheresis. Case report: A 58-year-old male was admitted to a local hospital due to polydipsia, polyuria, and weight loss for 2 months. ⋯ However, the urinary germanium concentration exceeded the normal level after three months, indicating an accumulation of germanium in the organs and tissues. The patient's clinical symptoms ameliorated and the functions of kidney, liver and pancreatitis gradually recovered. Conclusion: Combined CVVHDF with plasmapheresis is an effective treatment for germanium poisoning and the associated multiple organ dysfunctions.

Pragmatic Clinical Trial
Validation of Spanish version of the human papilloma virus impact profile (HIP).
Objective: To examine the construct validity and reliability of the Spanish version of the HPV Impact Profile scale (HIP) among women in Medellin, Colombia. Methods: We conducted a nested analysis of data from the pragmatic randomized controlled trial "Evaluation of Strategies for Optimal Clinical Management of Women with Atypical Squamous Cells of Undetermined Significance" (ASCUS-COL; NCT02067468). Women with Atypical Squamous Cells of Undetermined Significance (ASCUS) were randomly assigned to one of three triage strategies (Pap smear, colposcopy, HPV). ⋯ The factor structure was similar among the tree measures and the model preserved acceptable goodness of fit (RMSEA = 0.079, CFI:0.86). The Cronbach's alpha for the total score was 0.91, with the lowest score for sexual impact (0.49) and the highest score for worries and concerns (0.90). Conclusions: The Spanish version of the HIP had adequate reliability and construct validity, and its use could be considered in clinic and research settings.

Objective: Atrial fibrillation (AF) is present in up to 17% of patients in skilled nursing facilities (SNFs). This study compared healthcare resource utilization (HRU) and costs between AF patients initiating rivaroxaban or warfarin in SNFs. Methods: Using de-identified claims from Optum Clinformatics Extended Data Mart (1 January 2013 to 31 December 2017), this retrospective cohort study indexed AF patients with first SNF admission during which rivaroxaban or warfarin was initiated within 3 days of admission. ⋯ Total all-cause healthcare costs 100 days post-index SNF were $8746 lower with rivaroxaban versus warfarin (p < .0001). Conclusions: In the SNF setting, AF patients treated with rivaroxaban had 5-day shorter length of stay, lower HRU, and lower all-cause total and medical costs compared to warfarin, despite higher treatment costs. These findings may help inform clinical decision-making to reduce economic burden.
