BackgroundInnovative care models such as public-private partnerships (PPPs) may help meet the challenge of providing cost-effective high-quality care for the steadily growing and complex chronic kidney disease population since they combine the expertise and efficiency of a specialized dialysis provider with the population care approach of a public entity. We report the five-years main clinical outcomes of a population of patients treated on hemodialysis within a PPP-care model in Italy.MethodsThis descriptive retrospective cohort study consisted of all consecutive hemodialysis patients treated in the NephroCare-operated Nephrology and Dialysis unit of the Seriate Hospital in 2012–2016, which exercises a PPP-care model. Clinical and treatment information was obtained from the European Clinical Database. Hospitalization outcomes and cumulative all-cause mortality incidences that accounted for competing risks were calculated.ResultsWe included 401 hemodialysis patients (197 prevalent and 204 incident patients) in our study. The mean cohort age and age-adjusted Charlson Comorbidity Index were 67.0 years and 6.7, respectively. Patients were treated with online high-volume hemodiafiltration or high-flux hemodialysis. Parameters of treatment efficiency were above the recommended targets throughout the study period. Patients in the PPP experienced benefits in terms of hospitalization (average number of hospital admissions/patient-year: 0.79 and 1.13 for prevalent and incident patients, respectively; average length of hospitalization: 8.9 days for both groups) and had low cumulative all-cause mortality rates (12 months: 10.6 and 7.8%, 5 years: 42.0 and 35.9%, for prevalent and incident patients, respectively).ConclusionsResults of our descriptive study suggest that hemodialysis patients treated within a PPP-care model framework received care complying with recommended treatment targets and may benefit in terms of hospitalization and mortality outcomes.Electronic supplementary materialThe online version of this article (10.1186/s12882-019-1224-2) contains supplementary material, which is available to authorized users.

<b><i>Introduction:</i></b> Cognitive deficits and metabolic disturbances are among the main determinants of functional impairment and reduced life expectancy in patients with schizophrenia, and they may share underlying biological mechanisms. Among these, interleukin-1β (IL-1β), a key mediator of inflammatory response, is of particular interest. IL-1β C-511T polymorphism has been associated with neuropsychiatric conditions and, in the general population, with cognitive and metabolic alterations. This study aims to evaluate the effects of the IL-1β C-511T polymorphism on both cognition and metabolic syndrome in a sample of patients affected by schizophrenia, with a focus on sex differences. <b><i>Methods:</i></b> 138 patients with schizophrenia were assessed for metabolic parameters and neurocognitive measures by means of the Brief Assessment of Cognition Scale. The effects of IL-1β C-511T polymorphism on cognition and metabolic syndrome were evaluated in the context of general linear models. <b><i>Results:</i></b> The analysis showed a significant interaction between IL-1β genotype and sex on 2 core cognitive domains. In detail, among CC homozygous, females outperformed males on processing speed, while among T carriers, males outperformed females on executive functions. A significant interaction also emerged between metabolic syndrome, sex, and IL-1β genotype for executive functions, with worse performance for T carrier females with metabolic syndrome. No significant direct effect was observed for metabolic syndrome on cognition. <b><i>Conclusion:</i></b> These findings support the hypothesis that IL-1β polymorphism could play a key role in mediating the complex and refined relationship between metabolic syndrome and cognitive performance.

Background: Cognitive deficits are associated with schizophrenia and show a progressive worsening, often being unresponsive to treatment. New antipsychotic molecules acting as antagonist at the serotoninergic 5-hydroxytryptamine receptor 7 (e.g. lurasidone) or partial agonists at dopamine D3 receptor (e.g. cariprazine) could have an impact on cognition in this patient group. Objective: The aim of the systematic review is to explore the efficacy of lurasidone and cariprazine in improving cognition in both animal models and human studies. Methods: The following terms: (lurasidone AND cognit*) OR (cariprazine AND cognit*) were searched in Web of Science from inception to December 2021. We included all studies that assessed changes in cognitive function after treatment with cariprazine or lurasidone. Results: Of 201 selected articles, 36 were included. Twenty-four articles used animal models (rats, mice and marmosets), five evaluating the effects of cariprazine and 19 the effects of lurasidone. Twelve articles were clinical studies (cariprazine n = 2; lurasidone n = 10). In both animal and human studies lurasidone showed a greater efficacy on cognitive performance compared to placebo, quetiap- ine, ziprasidone or treatment-as-usual. Cariprazine was superior to other antipsychotics in improving cognitive functions in both animal and human studies. Conclusion: The cognitive effect of lurasidone could be explained by its potent antagonism at the 5- HT7 receptors combined with partial agonism at 5-HT1A receptors. The pro-cognitive effect of cariprazine is probably explained by its very high affinity for D3 receptors. Head-to-head studies com- paring lurasidone and cariprazine are needed to establish the “first-choice” treatment for cognitive dys- function associated with schizophrenia.
