The article presents a study which examined the hypothesis that airway mucus viscoelastic properties, as measured by rheology in critically ill patients who are receiving invasive mechanical ventilation correlates with its clinical mucus classification score. Topics discussed include clinical assessment of mucus properties, how rheologic properties are determined, and correlation between clinical mucus assessment and mucus rheology.

Respiratory syncytial virus (RSV) bronchiolitis is a leading cause of global child morbidity and mortality. Every year, seasonal RSV outbreaks put high pressure on paediatric intensive care units (PICUs) worldwide, including in the Netherlands, and this burden appears to be increasing. Weather conditions have a strong influence on RSV activity, and climate change has been proposed as a potential important determinant of future RSV-related health care utilisation. In this national study spanning a total of 13 years with 2161 PICU admissions for RSV bronchiolitis, we aimed (1) to identify meteorological variables that were associated with the number of PICU admissions for RSV bronchiolitis in the Netherlands and (2) to determine if longitudinal changes in these variables occurred over time as a possible explanation for the observed increase in PICU burden. Poisson regression modelling was used to identify weather variables (aggregated in months and weeks) that predicted PICU admissions, and linear regression analysis was used to assess changes in the weather over time. Maximum temperature and global radiation best predicted PICU admissions, with global radiation showing the most stable strength of effect in both month and week data. However, we did not observe a significant change in these weather variables over the 13-year time period. Based on our study, we could not identify changing weather conditions as a potential contributing factor to the increased RSV-related PICU burden in the Netherlands. [ABSTRACT FROM AUTHOR]

Viral bronchiolitis, which is most commonly caused by an infection with the respiratory syncytial virus (RSV), can lead to respiratory difficulties in young children which may require hospitalization. Despite years of research and medical trials, the mainstay of bronchiolitis treatment remains supportive only. This review provides an overview of the history of different treatments for bronchiolitis, including those that failed, as well as new therapies that are under study. Future studies for the treatment of bronchiolitis should consider different age-groups, important subgroups (i.e., those with a prior history of wheezing, those with a family history of asthma and those with non-RSV viral etiologies) whose response to treatment may differ from that of the composite group., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: MSS: Participates on the speaker’s bureau for Sanofi Pasteur.

Background: In 2010, we published an often-cited case report describing smoking cessation and substantial weight loss after deep brain stimulation (DBS) for obsessive-compulsive disorder (OCD) in an obese patient. To test whether this single observation was also observed in the treated population at large, the weight changes of a larger cohort of patients who underwent DBS for OCD or major depressive disorder (MDD) were studied., Results: Data were available for 46 patients (30 OCD and 16 MDD patients; mean age 46.2 years, SD 10.9) with an average baseline body mass index (BMI) of 28.0 (SD 7.3), 26 of whom (57%) were overweight (n = 11), obese (n = 12), or morbidly obese (n = 3). Mean follow-up was 3.8 years (range 10 months to 8.7 years, SD 2.3), after which the average BMI was 28.1 (SD 7.0), not significantly different from baseline. The average BMI of the 15 patients with (morbid) obesity at baseline decreased from 36.8 to 34.6 (ns), while the average BMI of the 31 normal or "only" overweight patients at baseline increased from 23.8 to 25.0 (ns)., Conclusion: There was no significant change in body weight on group level after DBS for either OCD or MDD., (© 2017 The Author(s) Published by S.
