Purpose: Over the last two decades, increasing attention has been paid to environmental toxins and their effects on the female reproductive system. Endocrine disrupting chemicals (EDCs) are exogenous substances or mixtures that can mimic the action of steroid hormones and interfere with their metabolism. Advanced glycation end products (AGEs) are proinflammatory molecules that can interact with cell surface receptors and mediate the triggering of proinflammatory pathways and oxidative stress. ⋯ They favor PCOS/OC development through different mechanisms that finally lead to hormonal and metabolic disruption and epigenetic modifications. Conclusions: Environmental toxin exposure in PCOS women could favor neoplastic transformation by exacerbating and potentiating some PCOS features. Further research, although difficult, is needed in order to prevent further diffusion of these substances in the environment, or at least to provide adequate information to the population considered at risk.

Multicenter Study Observational Study
Patient-reported outcomes in elderly patients with type 2 diabetes mellitus treated with dual oral therapy: a multicenter, observational study from Italy.
Objective: To assess patient-reported outcomes after two years of use of dual oral anti-diabetes drug (OAD) therapy in elderly people (≥65 years) with type 2 diabetes mellitus (T2DM) from Italy under real-life settings. Methods: 3-AGE was a prospective, non-interventional study in elderly people with T2DM inadequately controlled on metformin monotherapy (defined as glycated hemoglobin [HbA1c] 7.0-9.0%), in whom a second OAD was prescribed. Primary endpoint was to assess the physical and psychological symptoms associated with T2DM from baseline to 24 months using the Diabetes Symptom Check List revised (DSC-R) questionnaire. ⋯ Physicians expressed good satisfaction with patients' treatment (across efficacy, tolerability and compliance domains) at Month 12. Overall, 32 adverse reactions (in 24 patients) and four hypoglycemic episodes were reported during the 24 months. Conclusion: Addition of a second OAD improved physical and psychological symptoms associated with T2DM and was well tolerated in elderly people under real-life settings.

The mirogabalin ALDAY phase 3 program in pain associated with fibromyalgia: the lessons learned.
Aims: The main aim of this work was to identify and to share the lessons learned from the negative outcome of the mirogabalin ALDAY phase 3 clinical program in pain associated with fibromyalgia. These lessons are important to improve planning and design of future phase 3 programs in fibromyalgia. Methods: A systematic review from Cochrane Library, Medline, Embase, clinicaltrials.gov, pharmaceutical companies, and regulatory agencies' websites, was carried out starting from the development of gabapentin, the first α2δ ligand studied for the treatment of neuropathic pain and ending with the mirogabalin program. ⋯ Outcome: In terms of main lessons learned from ALDAY, the first was the need for a comprehensive patient-focused strategy to preliminarily identify the challenges of fibromyalgia based on patient perspective and study complexity. Second, there was a need for a harmonized, truly patient-centric, global regulatory guidance accepted by regulatory agencies. Third, ALDAY proved that a phase 2 proof of concept, dose ranging study is necessary before commencing any phase 3 program in fibromyalgia.

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.
