Intranasal insulin for the treatment of olfactory dysfunction: a protocol for a systematic review and meta-analysis.

Introduction: Olfactory dysfunction (OD) is a prevalent nasal affliction that has detrimental effects on the patients' quality of life and safety. Conventional therapeutic strategies have various limitations such as high costs, prolonged treatment durations and adverse side effects. Intranasal insulin is a novel intervention for the management of OD.

Sex-related differences in clinical outcomes and predictive factors in the very elderly patients with ACS undergoing PCI.

Background: As shown in previous studies, there may be sex-related differences in clinical outcomes in patients with acute coronary syndromes (ACS) after percutaneous coronary intervention (PCI). However, the benefits of PCI in very elderly ACS patients and the gender differences were poorly described and understood. We investigated the clinical characteristics and outcomes after PCI by sex stratification, and the predictive factors of major adverse cardiovascular and cerebrovascular events (MACCE) in this very elderly ACS cohort.
