Effectiveness of a Meningococcal Group B Vaccine (4CMenB) in Children.

Background: In September 2015, the four-component, protein-based meningococcal serogroup B vaccine (4CMenB; Bexsero) became available for private purchase in Spain.

Methods: We conducted a nationwide matched case-control study to assess the effectiveness of 4CMenB in preventing invasive meningococcal disease in children. The study included all laboratory-confirmed cases of invasive meningococcal disease in children younger than 60 months of age between October 5, 2015, and October 6, 2019, in Spain.

The COPD Comorbidome in the Light of the Degree of Dyspnea and Risk of Exacerbation.

The BODE group designed a bubble chart, analogous to the solar system, which depicts the prevalence of each disease and its association with mortality and called it a "comorbidome". Although this graph was used to represent mortality and, later, the risk of needing hospital admission, it was not applied to visualize the association between a set of comorbidities and the categories of the GOLD 2017 guidelines, neither according to the degree of dyspnea nor to the risk of exacerbation. For the purpose of knowing to which extent each comorbidity associates with each of the two conditions-most symptomatic group (groups B and D) and highest risk of exacerbation (groups C and D)-we performed a analysis based on the comorbidome.

Health Status in Patients with COPD According to GOLD 2017 Classification: Use of the COMCOLD Score in Routine Clinical Practice.

The COMCOLD score was developed to quantify the impact of comorbidities on health status in patients with chronic obstructive pulmonary disease (COPD). The objective of this study is to evaluate the association between health status in outpatients with COPD according to COMCOLD score and the GOLD 2017 groups according to symptoms (B and D vs. A and C) and exacerbations (C and D vs.
