Review Meta AnalysisInconclusive evidence for non-inferior immunogenicity of two- compared with three-dose HPV immunization schedules in preadolescent girls: A systematic review and meta-analysis.
The European Medicines Agency (EMA) recently approved two-dose immunization schedules for bivalent (HPV 16/18) and quadrivalent (HPV 6/11/16/18) human papillomavirus (HPV) vaccines in nine to fourteen and thirteen year-old-girls, respectively. Registration was based on trials comparing immunogenicity of two-dose schedules in girls 9-14 years to three-dose schedules in young women 15-26 years. We evaluate comparability of antibody levels between and within age groups and discuss potential implications for monitoring the effectiveness of HPV vaccination. ⋯ Two-dose immunization of girls has non-inferior immunogenicity compared to a three-dose schedule among young women. However, non-inferior immunogenicity of two- compared with three-dose schedules within girls has not been shown at all time points. Due to this inconclusive evidence, implementation of two-dose HPV vaccination needs to be monitored closely.

Observational StudyMicrobiology and outcomes of community acquired pneumonia in non cystic-fibrosis bronchiectasis patients.
It is general belief that Non-cystic fibrosis bronchiectasis (NCFB) is characterized by frequent community-acquired pneumonia. Nonetheless, the knowledge on clinical characteristics of CAP in NCFBE is poor and no specific recommendations are available. We aim to investigate clinical and microbiological characteristics of NCFBE patients with CAP. ⋯ NCFBE-CAP patients are usually older and have more comorbidities but similar outcomes than general CAP population. Usual CAP pathogens, such as S. pneumoniae, are also involved in NCFBE-CAP but P. aeruginosa and other Enterobacteriaceae were globally more frequent than in CAP. Therefore, a wide microbiological investigation should be recommended in all NCFBE-CAP cases as well as routine pneumococcal vaccination for prevention of pneumonia.

ReviewEarly-onset pneumonia after out-of-hospital cardiac arrest.
Early-onset pneumonia (EOP) is a common complication after successful cardiopulmonary resuscitation. Currently, EOP diagnosis is difficult because usual diagnostic tools are blunted by the features of post-cardiac arrest syndrome and therapeutic hypothermia itself. When the diagnosis of EOP is suspected, empiric antimicrobial therapy should be considered following bronchopulmonary sampling. ⋯ Therapeutic hypothermia has been recognized as an independent risk factor for this infectious complication. All together, these observations underline the need for future prospective clinical trials to better delineate pathogens and risk factors associated with EOP. In addition, there is a need for diagnostic approaches serving the accurate diagnosis of EOP.

The context in which a sepsis guideline is to be used is important and to a large extent determines whether it will be implemented successfully. Factors such as lack of time and resources, lack of reimbursement and organizational constraints may also preclude adoption of guidelines. ⋯ A holistic approach is necessary to address all issues that may be impediments to guideline adoption and adherence. This approach would include a rigorous transparent method to craft the guideline, which includes both clinicians and policy makers and addresses cultural and resource issues.
