There is limited evidence of the potential benefits of the use of high-flow nasal cannula (HFNC) for the management of bronchiolitis in the ward. Our aim is to describe the ventilation trends for bronchiolitis in our hospital along with the introduction of an HFNC ward protocol and to determine the need for respiratory support escalation and transfer to an intensive care unit (ICU). A retrospective analytical observational study of children < 12 months old requiring admission for a first RSV bronchiolitis episode in a single centre from January 2009 to December 2018. The sample was divided into four groups according to the type of respiratory support that would ensure the clinical stability of the infants on admission. A total of 502 infants were recruited. The total number and percentage of patients admitted in the ward grew progressively over time. Simultaneously, there was an increase in HFNC and, paradoxically, an increase in ICU transfers. The risk of failure was higher for those who required HFNC or CPAP for clinical stabilisation in the first 12 h after admission. Moreover, the risk of failure was also higher in children with standard oxygen therapy promptly escalated to HFNC, especially if they had atelectasis/viral pneumonia, coinfections or a history of prematurity. Despite the limitations of a retrospective analysis, our study reflects usual clinical practice and no correlation was found between the usage of HFNC and a shorter length of hospital stay or less time spent on oxygen therapy.

(1) Background: Endometriosis and chronic endometritis (CE) are pathologies that are positively correlated and have similar paracrine and immunological alterations. This leads us to wonder whether their interrelationship plays a role in the etiopathogenesis or progression of endometriosis. The purpose of this study is to evaluate whether patients with endometriosis and CE have a more advanced stage of the disease, higher rates of pain, a poorer response to treatment, and a greater association with other pathologies compared to women with endometriosis without CE. (2) Methods: This is a cross-sectional pilot design study of 37 women with endometriosis who underwent endometrial aspiration for the diagnosis of CE and were followed up at the Puerta de Hierro Hospital. (3) Results: All patients with CE in this study had adenomyosis (p = 0.004). There was a relatively homogeneous distribution of CE in the different endometriosis phenotypes. The group of patients with endometriosis and CE indicated higher rates of pain during ovulation and less pain during defecation and sexual intercourse. (4) Conclusions: A high prevalence of CE was observed in patients with endometriosis, as well as a trend suggesting a relationship between CE and adenomyosis that should be studied. The following article attempts to reflect a link found between endometriosis and chronic endometritis, which would be important when prescribing personalized medicine, as it forces us to look for a specific disease in a specific patient profile.
