ABP 501 is a biosimilar to the anti-tumor necrosis factor-alfa monoclonal antibody adalimumab and despite its effectiveness and safety in the treatment of psoriasis was demonstrated in randomized clinical trials, no real-life data are available, in particular in patients undergoing non-medical switch from originator to biosimilar. ⋯ AB- 501 is an effective treatment for plaque-type psoriasis and psoriatic arthritis regardless if patients are originator-naïve or if they were switched from the reference product.

Those invested in the outcome of specific decisions may seek to inform the decision-maker by generating relevant evidence. With multiple decision-makers, the evidence generator benefits from understanding whether their needs differ. This was explored using relevant stakeholders' preferences on quality indicators (QIs) of rare disease patient registries (RDRs), a common vehicle for generating evidence, to support the adoption of new medicines. ⋯ A multiple stakeholder approach for generating real-world evidence can be justified. The potential mismatch of 54.9% between pharma and non-pharma stakeholders indicates a critical misalignment between generator and consumer of its RWE. Pharmaceutical SHG's were highlighted for greater alignment with Patients and Payor (non-pharma) groups.

Methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism is the main genetic modulator of homocysteine. Data suggest a potential association of homozygosity for the TT MTHFR genotype with premature myocardial infarction (MI). We explored whether TT homozygosity is associated with long-term prognosis in patients with premature ST-segment elevation MI (STEMI). ⋯ Homozygosity for the TT MTHFR is an independent long-term predictor of cardiac death in patients with premature STEMI.

To evaluate geographic variation in the prevalence of autosomal dominant polycystic kidney disease (ADPKD) in the US, including ADPKD at risk of rapid progression. ⋯ This estimate for ADPKD prevalence is consistent with previously reported national estimates, with regional variation suggesting that ADPKD might be under-diagnosed in rural areas with more limited access to care. More than one-third of ADPKD patients presented risk factors associated with rapid progression, highlighting the need for timely identification, as disease-modifying therapy may delay progression to end-stage renal disease.
