Consolidation of health care providers, and vertical integration of physicians with hospitals and/or payers has accelerated over the past 15 years. Although there is potential for consolidation to improve patient care, efficiencies and reduce overhead costs, participants in our conference identified that almost all research on consolidation has shown increased cost without improvement in outcomes or the experience of care. To provide a framework for considering the impact of consolidation, future research and analysis we offer 4 themes: (1) to move forward, we need to look back at historical drivers, value creation, and unintended consequences; (2) not all consolidation is created equally; (3) real-time, continuous evaluation is critical for improvement; and (4) a policy blueprint is desperately needed.

Impaired insight into illness occurs in up to 98% of patients with schizophrenia, depending on the stage of illness, and leads to negative clinical outcomes. Previous neuroimaging studies suggest that impaired insight in patients with schizophrenia may be related to structural and functional anomalies in frontoparietal brain regions. To date, limited studies have investigated the association between regional cerebral blood flow (CBF) and impaired insight in schizophrenia.

Neutrophils are the most abundant cell type in the airways of tuberculosis patients. Mycobacterium tuberculosis (Mtb) infection induces the release of neutrophil extracellular traps (NETs); however, the molecular regulation and impact of NET release on Mtb pathogenesis are unknown. We find that during Mtb infection in neutrophils, PAD4 citrullinates histones to decondense chromatin that gets released as NETs in a manner that can maintain neutrophil viability and promote Mtb replication.

The research explored the chemical characteristics of essential oils (EOs) extracted from the peels of four citrus fruits grown in northeastern Peru (lime, sweet lemon, mandarin and orange). The essential oils were extracted by hydrodistillation using a green solvent, and subsequently, their physicochemical profile, bioactive, heat capacity, and RAMAN mapping were determined; in addition, the volatile composition was determined by gas chromatography (GC-MS), and the main phenols by liquid chromatography (UHPLC). The results evidenced that sweet lemon and mandarin essential oils had higher antioxidant activity (1592.
