RESUMEN
Clinical practice guidelines (CPGs) are intended to support clinical decisions and should be based on high-quality evidence. The objective of the study was to evaluate the quality of evidence supporting the recommendations issued in CPGs for therapy, diagnosis, and prevention of hospital-acquired and ventilator-associated pneumonia (HAP/VAP). CPGs released by international scientific societies after year 2000, using the Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) methodology, were analyzed. Number and strength of recommendations and quality of evidence (high, moderate, low, and very low) were extracted and indexed in the aforementioned sections. High-quality evidence was based on randomized control trials (RCT) without important limitations and exceptionally on rigorous observational studies. Eighty recommendations were assessed, with 7 (8.7%), 24 (30.0%), 29 (36.3%), and 20 (25.0%) being supported by high, moderate, low, and very low-quality evidence, respectively. Highest evidence degree was reported for 26 prevention recommendations, with 7 (26.9%) supported by high-quality evidence and no recommendation based on very low-quality evidence. In contrast, among 9 recommendations for diagnosis and 45 for therapy, none was supported by high-quality evidence, in spite of being recommended as strong in 33.3% and 46.7%, respectively. Among HAP/VAP diagnosis recommendations, the majority of evidence was rated as low or very low-quality (55.6% and 22.2%, respectively) whereas among HAP/VAP therapy recommendations, 4/5 were rated as low and very low-quality (40% each). In conclusion, among HAP/VAP international guidelines, most recommendations, particularly in therapy, remain supported by observational studies, case reports, and expert opinion. Well-designed RCTs are urgently needed.

Invasive aspergillosis (IA) is a severe life-threatening infection with challenges in therapy. The aim was to evaluate the level of evidence (LOE) supporting recommendations in clinical practice guidelines (CPGs) of IA and changes over time. Search on CPG on IA released between 2000 and 2019 was done. Last versions were evaluated and compared with previous versions. Recommendations were classified by LOE as A (multiple randomized controlled trial (RCT) or meta-analysis), B (data from a single RCT or observational studies), or C (observational studies with limitations, case series, or expert opinion). Diagnosis recommendations were excluded. Five CPG from three groups of scientific societies were identified: the 2016 Infectious Diseases Society of America/American Thoracic Society (IDSA/ATS), 2017 European Society of Clinical Microbiology Infectious Diseases/European Confederation of Medical Mycology/European Respiratory Society (ESCMID/ECMM/ERS), 2018 Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC) CPGs, and their previous versions (2008 IDSA/ATS and 2011 GEMICOMED/SEIMC). ECMID/ECMM/ERS have not published any previous version. From 511 recommendations analyzed, 80 were classified as LOE A (15.7%), 223 LOE B (43.6%), and 208 LOE C (40.7%). Among 238 strong recommendations, only 57 (24.0%) were supported by LOE A. When comparing recent CPGs with previous versions, the proportion of recommendations supported by LOE A did not significantly increase over time (IDSA/ATS: 13.3% [2016] vs. 14.8% [2008], p = 0.798; and SEIMC: 22.6% [2018] vs. 19% [2011], p = 0.568). In conclusion, IA is a condition with an urgent unmet clinical need for more high-quality randomized trials.

Optimal clinical decisions should be supported by clinical practice guidelines (CPG) based on evidence generated from randomized clinical trials (RCT). We aimed to evaluate the class and level of evidence (LOE) supporting the international community-acquired pneumonia (CAP) guidelines and their variation over time. The 2019 Infectious Diseases Society of America/American Thoracic Society (IDSA/ATS) and the 2011 European Respiratory Society/European Society Clinical Microbiology Infectious Diseases (ERS/ESCMID) CPG and its immediate predecessors (2007 and 2005) were evaluated. The number of recommendations and distribution as LOE A (supported by multiple RCT or a single, large RCT), B (supported by data from a single RCT or observational studies) and C (expert opinion, case studies, or standard of care) was identified. Overall, recommendations for diagnosis, management, and prevention were graded as strong in 51.4%, 62.9%, and 23.5% in spite that they were supported by LOE A in 5.7%, 11.1%, and 52.9%, respectively. In the 2019 ATS/IDSA guidelines (39 recommendations), 7.7% (n = 3) recommendations were classified as LOE A, 30.8% (n = 12) as LOE B, and 61.5% (24%) as LOE C. Across the 2011 ERS/ESCMID guidelines (68 recommendations), 21.2% (n = 14) recommendations were classified as LOE A, 4.6% (n = 3) as LOE B, and 74.2% (n = 49) as LOE C. When comparing with prior versions, the proportion of recommendations that were LOE A did not significantly increase in ERS/ESCMID (21.2% vs 20%) and decreased in ATS/IDSA (7.7% vs 32.0%). In conclusion, large randomized trials or network meta-analysis including comparison of regimens to identify high probability of best cure and mortality is an unmet clinical need on CAP.

BACKGROUND: The aim was to identify the causing organisms and assess the association of procalcitonin (PCT) with bacterial pneumonia within 24 hours of intensive care unit admission (ICU-A) among lung transplant (LT) adult recipients. METHODS: Secondary analysis from a prospective cohort study. All LT adults admitted to ICU for acute respiratory failure (ARF) over 5 years were included. Patients were followed until hospital discharge or death. RESULTS: Fifty-eight consecutive LT patients were enrolled. The most important cause of ICU-A due to ARF was pneumonia 29 (50%) followed by acute rejection 3 (5.2%) and bronchiolitis obliterans syndrome exacerbation 3 (5.2%). Microorganisms were isolated from 22/29 cases with pneumonia (75.9%): 17 (77.2%) bacterial, 4 (18.2%) viral, 1 (4.5%) Aspergillus fumigates, with Pseudomonas aeruginosa being the most common cause (45.5%) of pneumonia, with 10 patients presenting chronic colonization by P aeruginosa. Median [Interquartile range (IQR)] PCT levels within 24 hours after admission were higher in pneumonia (1.5 µg/L; IQR:0.3-22.0), than in non-pneumonia cases (0.2 µg/L; IQR:0.1-0.7) (P = .019) and PCT levels within 24 hours helped to discriminate bacterial pneumonia (8.2 µg/L; IQR:0.2-43.0) from viral pneumonia and non-pneumonia cases (0.2 µg/L; IQR:0.1-0.7). The overall negative predictive value for bacterial pneumonia was 85.1%, increasing to 91.6% among episodes after 6 months of LT. CONCLUSIONS: Causes of severe pneumonia in LT are changing, with predominant role of P aeruginosa and respiratory viruses. PCT ≤ 0.5 µg/L within 24 hours helps to exclude bacterial pneumonia diagnosis in LT adults requiring ICU-A. A negative PCT test allows antimicrobial de-escalation and requires an alternative diagnostic to bacterial pneumonia.

PURPOSE: The aim of this document was to develop standardized research definitions of invasive fungal diseases (IFD) in non-neutropenic, adult patients without classical host factors for IFD, admitted to intensive care units (ICUs). METHODS: After a systematic assessment of the diagnostic performance for IFD in the target population of already existing definitions and laboratory tests, consensus definitions were developed by a panel of experts using the RAND/UCLA appropriateness method. RESULTS: Standardized research definitions were developed for proven invasive candidiasis, probable deep-seated candidiasis, proven invasive aspergillosis, probable invasive pulmonary aspergillosis, and probable tracheobronchial aspergillosis. The limited evidence on the performance of existing definitions and laboratory tests for the diagnosis of IFD other than candidiasis and aspergillosis precluded the development of dedicated definitions, at least pending further data. The standardized definitions provided in the present document are aimed to speed-up the design, and increase the feasibility, of future comparative research studies.

BACKGROUND: Respiratory microbiome composition depends on an intricate balance between host characteristics, diet, and environmental factors. Some studies indicate a bidirectional relationship between respiratory microbiota and disease. Air pollution is consistently associated with increased respiratory morbidity and mortality in different populations and across different ages. The aim of this review was to report a summary of the evidence regarding the impact of air pollution on the upper and lower respiratory tract microbiome. METHODS: A literature search from interaction between air pollution and respiratory microbiome was performed (2010-2022). RESULTS: Sixteen studies demonstrated changes in microbiome with both environmental and household air pollution. Increasing levels of air pollutants are associated with lower relative abundance of Corynebacterium and increasing levels of pathogen colonization, such as Haemophilus influenzae, Moraxella catarrhalis, Streptococcus pneumoniae and Pseudomonas aeruginosa and Acinetobacter baumannii, altering the incidence and clinical course of respiratory infections. This ultimately leads to an excess of morbidity and mortality due to antimicrobial resistance. CONCLUSION: Changes of air pollution on the respiratory microbiome may influence respiratory infections in critical care. Use of probiotics may restore the diversity of baseline microbiome, preventing infections by resistant organisms in the critical care setting. Using protective equipment decreased the effect of air pollutants on increasing potentially pathogenic microorganisms.

BACKGROUND: Sex disparities are related to biological differences, which may have significant impact on patient and allograft outcomes. The aim was to investigate the impact of sex on clinical and safety outcomes after solid organ transplantation (SOT). METHODS: A systematic review and meta-analysis was performed. Observational studies comparing females vs. males after SOT were considered for inclusion after a systematic search of the Pubmed, Cochrane Library, and Web of Science databases conducted from 2016 to 2021. Primary outcome was mortality. PROSPERO register number: CRD42021282615. RESULTS: After retrieving 1103 studies, 22 observational studies (1,045,380 subjects) were finally deemed eligible for inclusion. Females accounted 36.3% of SOT recipients, but presented significantly lower mortality (odds ratio (OR): 0.87, 95% confidence interval (CI): 0.83-0.92, I2=78%). In subgroup analyses, mortality was significantly lower in females undergoing liver (OR: 0.89 95%CI: 0.86-0.92, I2=0%) or kidney transplantation (OR: 0.82 95%CI: 0.76-0.89, I2=72%). Male sex was consistently reported as a protective factor against hospital readmission. Among the outcomes, allograft dysfunction was influenced by a combination of donor-recipient sex and age. Data on overall infections were inconclusive. Several reports suggest a higher risk of malignancy among males. CONCLUSIONS: Females represent one-third of SOT recipients but have higher survival rates than males after liver and kidney transplantation. The impact on graft dysfunction was heterogeneous. While further research is warranted, our findings should encourage clinicians and researchers to consider sex as a factor when taking decisions regarding SOT management.

Background: Ventilator-associated pneumonia (VAP) represents a common hospital-acquired infection among mechanically ventilated patients. We summarized evidence concerning ventilator care bundles to prevent VAP. Methods: A systematic review and meta-analysis were performed. Randomized controlled trials and controlled observational studies of adults undergoing mechanical ventilation (MV) for at least 48 h were considered for inclusion. Outcomes of interest were the number of VAP episodes, duration of MV, hospital and intensive care unit (ICU) length of stay, and mortality. A systematic search was conducted in the MEDLINE, the Cochrane Library, and the Web of Science between 1985 and 2022. Results are reported as odds ratio (OR) or mean difference (MD) with 95% confidence intervals (CI). The PROSPERO registration number is CRD42022341780. Results: Thirty-six studies including 116,873 MV participants met the inclusion criteria. A total of 84,031 participants underwent care bundles for VAP prevention. The most reported component of the ventilator bundle was head-of-bed elevation (n=83,146), followed by oral care (n=80,787). A reduction in the number of VAP episodes was observed among those receiving ventilator care bundles, compared with the non-care bundle group (OR=0.42, 95% CI: 0.33, 0.54). Additionally, the implementation of care bundles decreased the duration of MV (MD=-0.59, 95% CI: -1.03, -0.15) and hospital length of stay (MD=-1.24, 95% CI: -2.30, -0.18) in studies where educational activities were part of the bundle. Data regarding mortality were inconclusive. Conclusions: The implementation of ventilator care bundles reduced the number of VAP episodes and the duration of MV in adult ICUs. Their application in combination with educational activities seemed to improve clinical outcomes.
RESUMEN
INTRODUCTION: The aim of this article is to summarize published information on systemic infective complications of tattoos to gain an update of the current picture. METHODS: A literature search was performed in PubMed database (2009-2019), and compared with a search without year restriction. Eligibility criteria were studies on systemic tattoo-related infections, including case reports, case series, outbreak investigations, reviews, and systematic reviews. RESULTS: We identified 17 manuscripts with systemic infections between 2009 and 2019, with one reported fatality. In contrast to the historical records, no reports of systemic tuberculosis, syphilis or viral (hepatitis or HIV) infections were reported within the study period. A few sporadic cases or Mycobacterium leprae (India) or regional lymphadenopathy associated with skin lesions in non-tuberculosis mycobacteria were identified. Persistent fever with rigour was common in bacterial bloodstream infections. One episode of staphylococcal toxic shock syndrome and several episodes of septic shock were reported, associated with cellulitis or necrotizing fasciitis within two weeks of the procedure, predominantly caused by pyogenic bacteria (S. aureus or streptococcus). Identification of lung or systemic embolisms in the absence of local symptoms, was indicative of (right or left) infective endocarditis. CONCLUSIONS: Bacterial bloodstream infections should be considered in subjects developing fever and rigour after tattoos, regardless of local symptoms. A shift in causative organisms has been documented, when comparing with historical reports. NTM are emerging organisms causing lymphadenopathy. Strict hygiene conditions are essential when performing a tattoo.

INTRODUCTION: Respiratory syncytial virus (RSV)-associated diseases have caused an estimated 1.8 million hospital admissions and 40,000 deaths among children. RSV can cause lower respiratory tract infections (LRTIs) in all age groups, adults with comorbidities, and immunocompromised patients. The aim was to summarize the evidence concerning efficacy and safety of ribavirin in subjects diagnosed with RSV associated with LRTI. METHODS: A systematic review and meta-analysis were performed. Eligible studies were observational (> 10 subjects) and randomized-controlled trials of subjects with aerosol/oral ribavirin for RSV-LRTI. Comparator was supportive care or placebo. Systematic search on PubMed, Cochrane Library, and Web of Science databases was conducted between January 2001 and January 2022. PROSPERO register number: CRD42022308147. RESULTS: After retrieving 907 studies, 10 observational studies and 1 randomized controlled trial were included (4/11 high quality of evidence). Seven studies included subjects with haematological malignancy/stem cell transplant, two lung transplants, and two healthy individuals. A total of 788 subjects diagnosed with RSV infection were included; 14.3% of them presented with only LRTI. Among 445 subjects treated with ribavirin, 195 (43.8%) received an aerosolized formulation. Pooled meta-analysis showed no differences in mortality [risk ratio (RR): 0.63; 95% confidence interval (CI): 0.28-1.42] in all subjects treated with aerosol/oral ribavirin compared to supportive care. In subgroup analysis, mortality was significantly lower in haematological subjects (RR: 0.32; 95% CI: 0.14-0.71), but did not differ significantly in lung transplant recipients (RR: 0.89; 95% CI 0.31-2.56). Oral ribavirin (vs. supportive care) was associated with increased viral clearance (RR: 2.60; 95% CI: 1.35-4.99). Seventeen adverse events were reported among 119 subjects, but none were severe. CONCLUSION: Ribavirin should be considered for treatment of RSV-LRTI in haematological subjects. There is a lack of evidence to support its use in lung transplant recipients. Oral formulation appears to be an easier, safe, and cost-effective alternative to aerosolized ribavirin. Further advances needs to focus on newer antivirals.

BACKGROUND: Solid-organ transplantation (SOT) from SARS-CoV-2 positive donors could be a life-saving opportunity worth grasping. We perform a systematic review to evaluate the recipient outcomes of SOT from donors with recent or current SARS-CoV-2 infection. METHODS: Search strategy was performed in PubMed, Cochrane COVID-19 Study Register, and Web of Science databases from the 1st of January 2019 to the 31st of December 2021. SOT adult recipients from a donor with past or current SARS-CoV-2 infection were elegible for inclusion. Outcomes were viral transmission, COVID-19 symptoms, mortality, hospital stay, and complications. PROSPERO Register Number: CRD42022303242 FINDINGS: Sixty-nine recipients received 48 kidneys, 18 livers and 3 hearts from 57 donors. Six additional transplants from positive lungs were identified. IgG+ anti-SARS-CoV-2 titers were detected among 10/16 recipients; only 4% (3/69) recipients were vaccinated. Non-lung transplant recipients received organs from 10/57 (17.5%) donors with persistent COVID-19. In 18/57 donors, SARS-CoV-2 RNA was detected (median 32 Cycle threshold [Ct]) at procurement. Among non-lung transplant recipients, SARS-CoV-2 viral transmission was not documented. Four patients presented delayed graft dysfunction, two patients acute rejection, and two patients died of septic shock. The median (IQR) hospital stay was 18 (11-28) days in recipients from symptomatic donors. Viral transmission occurred from three lung donors to their recipients, who developed COVID-19 symptoms. One of the recipients subsequently died. CONCLUSION: Use of non-lung (kidney, liver and heart) organs from SARS-CoV-2 positive donors seem to be a safe practice, with a low risk of transmission irrespective of the presence of symptoms at the time of procurement. Low viral replication (Ct > 30) was safe among non-lung donors, even if persistently symptomatic at procurement.

OBJECTIVES: To evaluate the evidence concerning the effectiveness of antiseptic barrier caps vs. manual disinfection in preventing central line-associated bloodstream infection (CLABSI). METHODS: The protocol of this systematic review and meta-analysis was pre-registered in PROSPERO (CRD42021259582). PubMed, Cochrane Library and Web of Science databases were searched from 2011 to 2021. Randomized-controlled trials (RCT) and observational studies on hospitalized patients of any age were included. RESULTS: Fourteen studies were included. Compared with manual disinfection, antiseptic barrier caps significantly reduced CLABSI rate per 1000 line-days (Standardized Mean Difference [SMD]: -0.02; 95%CI: -0.03 to -0.01) and number of CLABSI per patient (RR: 0.60; 95%CI: 0.41-0.89). Subgroup analysis showed that antiseptic barrier caps were more effective in reducing CLABSI rate per 1000 line-days in ICU (SMD: -0.02; 95%CI: -0.03 to -0.01) and non-ICU patients (SMD: -0.03; 95%CI: -0.05 to -0.01), adults (SMD: -0.02; 95%CI: -0.04 to -0.01), as in observational studies (SMD: -0.02; 95%CI: -0.02 to -0.01). Antiseptic barrier caps also significantly reduce CLABSI risk in ICU patients (RR: 0.65, 95%CI: 0.42-1.00), adults (RR: 0.50, 95%CI: 0.29-0.86), and observational studies (RR: 0.54; 95%CI: 0.32-0.91). No differences were found when only children or RCTs were taken into account. Median cost savings amongst studies were $21,890 [IQR 16,350-45,000] per CLABSI. CONCLUSIONS: Antiseptic barrier caps appear to be effective in reducing CLABSI. The real-world impact needs to be confirmed by RCTs.

BACKGROUND: Guidelines aim to standardize and optimize diagnosis and management. We evaluated the quality of evidence supporting recommendations from different international adult guidelines on bronchiectasis, and classified with the GRADE system. METHODS: Quality of eligible clinical practice guidelines was assessed for six domains using the AGREE II tool, with ≥ 80% rating as excellent. RESULTS: Seven guidelines (283 recommendations) were analyzed, and four of them were considered "recommended for use" (three reported after 2017 as excellent). Overall, 144 (50.9%) recommendations were based on low-quality evidence, representing 81.5% in diagnosis and 36.2% in therapy. In contrast, 5/92 (5.4%) and 40/191 (20.9%) recommendations regarding diagnostic and treatment (respectively) were based on high-quality evidence. Quality agreement ratings were significantly (p< 0.05) higher for guidelines delivered after 2015, progressing from 27.7% to 58.3%, qualifying as excellent. Highest scores were documented in the domains of "scope and purpose" followed by "clarifying of presentation" and "editorial independence". CONCLUSION: Updated guidelines reported after 2017 improved quality, although well-designed randomized clinical trials remain an unmet need. AGREE II quality assessment identified four guidelines qualified as recommended for use. Improvements are required in stakeholder involvement and applicability.

It remains unknown whether the type of aerosol generating device is affecting efficacy and safety among non-cystic fibrosis bronchiectasis (NCFB) adults. The proposal of this network meta-analysis (NMA) is to evaluate effectiveness and safety of inhaled antibiotics administered via dry powder inhaler (DPI) and via nebulizers (SVN) among adult patients with NCFB. Inclusion criteria were randomized-controlled trials, adults (≥18 years) with NCFB, and inhaled antibiotics administered via DPI as intervention. Search strategy was performed in PubMed, Web of Science, and Cochrane Library from 2000 to 2019. Sixteen trials (2870 patients) were included. Three trials (all ciprofloxacin) used DPIs and thirteen used SVN (three ciprofloxacin). Both DPI and SVN devices achieved similar safety outcomes (adverse events, antibiotic discontinuation, severe adverse events, and bronchospasm). Administration of ciprofloxacin via DPI significantly improved time to first exacerbation (87 days, 95% CI 34.3-139.7) and quality of life (MD -7.52; 95% CI -13.06 to -1.98) when compared with via SVN. No other significant differences were documented in clinical efficacy (at least one exacerbation, FEV1% predicted) and microbiologic response (bacterial eradication, emergence of new potential pathogens, and emergence of antimicrobial resistance) when comparing devices. Our NMA documented that time to first exacerbation and quality of life, were more favorable for DPIs. Decisions on the choice of devices should incorporate these findings plus other criteria, such as simplicity, costs or maintenance requirements.
RESUMEN
INTRODUCTION: Varicella zoster virus (VZV) reactivation has been reported following vaccination for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), but the real extent remains unknown. METHODS: We conducted a systematic review to summarize evidence of VZV reactivation or infection following SARS-CoV-2 vaccination. Episodes after coronavirus disease-2019 (COVID-19) were also identified. Related articles were identified in PubMed and EMBASE databases till December 31, 2021 using the terms "varicella zoster" and "COVID-19â³. PROSPERO Register Number: CRD42021289399. RESULTS: The search revealed 314 articles, of which 55 met the inclusion criteria. VZV manifestations were documented in 179 (82.1%) subjects following SARS-CoV-2 vaccination and in 39 (17.9%) patients with COVID-19. Among the vaccinated, median (IQR) age was 56.5 (42-70) years, and 56.8% were female. Twenty-one (16.8%) were immunosuppressed. The median (IQR) latency time after vaccination was 6 (3-10) days, and 84.4% received mRNA vaccines. VZV reactivation occurred following a first dose (68.2%), a second dose (12.8%) or a booster (0.6%). The most important VZV manifestation was dermatome herpes zoster rash, which accounted for 86.4% of events in vaccinated subjects. Twenty patients (11.3%) presented serious VZV events after vaccination, with Herpes Zoster ophthalmicus (5.6%) and post-herpetic neuralgia (3.4%) predominating. No VZV pneumonia or deaths were recorded. Antiviral prescriptions were made in 96.2% of vaccinated subjects. No significant differences between vaccinated and infected subjects were found. CONCLUSION: This study indicates that the occurrence of VZV reactivation is clinically relevant. However, our findings suggest that COVID-19 vaccination is safe, and remains strongly recommended.

BACKGROUND: The Centres for Disease Control and Prevention (CDC) broadened the focus of surveillance from ventilator-associated pneumonia to ventilator-associated event (VAE) for quality purposes. No paediatric definition of VAE (PaedVAE) has been accurately validated. We aimed to analyse the incidence and impact on patient outcomes resulting from the application of the adult and two paediatric VAE (PaedVAE) criteria. SECONDARY OBJECTIVE: to evaluate VAE/PaedVAE as factors associated with increased duration of mechanical ventilation (MV) and Paediatric Intensive Care Unit (PICU) stay. METHODS: Multicentre observational prospective cohort study in 15 PICUs in Spain. VAEs were assessed using the 2013/2015 CDC classification. PaedVAE were assessed using the CDC definition based on mean airway pressure (MAP-PaedVAE) versus a paediatric definition based on positive end-expiratory pressure (PEEP-PaedVAE). Children who underwent MV ≥ 48 h were included. RESULTS: A total of 3626 ventilator-days in 391 patients were analysed. The incidence of VAE, MAP-PaedVAE and PEEP-PaedVAE was 8.55, 5.24 and 20.96 per 1000 ventilator-days, respectively. The median time [IQR] for VAE, MAP-PaedVAE and PEEP-PaedVAE development from the MV onset was 4 [3-12.5], 4 [3-14], and 5 [3-7.75] days, respectively. Among survivors, all three were associated with increased MV duration (> 7 days) and PICU stay (> 10 days) at univariate analysis. Multivariate analysis showed that PEEP-PaedVAE was the only definition independently associated with MV above 7 days [OR = 4.86, 95% CI (2.41-10.11)] and PICU stay [OR = 3.49, 95% CI (1.68-7.80)] above ten days, respectively. CONCLUSIONS: A VAE definition based on slight PEEP increases should be preferred for VAE surveillance in children.

BACKGROUND: There is scarce evidence verifying the impact of neuraminidase inhibitors (NAIs) in reducing influenza complications. The aim was to evaluate the available evidence from randomized-controlled trials (RCT) regarding the efficacy and safety of NAIs in reducing influenza complications. METHODS: A systematic search of the literature was performed in the Cochrane Library, PubMed and Web of Science databases (2006-2019). Eligibility criteria were RCT that enrolled patients of any age or clinical severity with seasonal influenza (H1N1, H3N2, or B) or influenza-like syndrome and receiving NAIs comparing to placebo therapy. RESULTS: Eighteen RCTs (9004 patients) were included: nine focused on oral oseltamivir, six on inhaled zanamivir, and three on intravenous peramivir. Administration of NAIs therapy significantly decreased the time to clinical resolution (median difference: -17.7 hours; and total influenza-related complications (OR: 0.64, 95%CI: 0.51-0.82). In addition, NAIs significantly decreased acute otitis media complication (OR: 0.50, 95%CI: 0.31-0.82) and need for antibiotic treatment (OR: 0.64, 95%CI: 0.46-0.90); and showed a trend towards a reduced occurrence of pneumonia (OR: 0.44, 95%CI: 0.10-2.00), bronchitis (OR: 0.80, 95%CI: 0.43-1.48), sinusitis (OR: 0.73, 95%CI: 0.40-1.32), asthma exacerbations (OR: 0.57, 95%CI: 0.28-1.16), and hospitalizations (OR: 0.57, 95%CI: 0.24-1.38). The overall proportion of AEs tend to increase with NAIs treatment (OR: 1.16, 95%CI: 0.92-1.47). Use of NAIs was associated with a significant increase of nausea and vomiting (OR: 1.61, 95%CI: 1.04-2.50) and a decrease on diarrhea (OR: 0.81, 95%CI: 0.65-1.00). CONCLUSIONS: NAIs are effective in reducing time to clinical resolution, total influenza-related complications, otitis media, and need of antibiotic administration. Reductions on mortality, pneumonia, asthma exacerbations or hospitalization rates only did demonstrate a trend benefit in favor of NAIs. The only significant AE is the increased occurrence of nausea and vomiting.

BACKGROUND: Scarce evidence verifying the clinical impact of baloxavir on influenza complications is found. METHODS: PubMed, Cochrane Library, and Web of Science databases were searched through December 2020. Randomized-controlled trials (RCT) that enrolled patients with laboratory-confirmed influenza receiving neuraminidase inhibitors (NAI) or baloxavir comparing to placebo were assessed. PROSPERO Registration-number: CRD42021226854. RESULTS: Twenty-one RCTs (11,697 patients) were included. Antiviral administration significantly reduced time to clinical resolution (mean difference: -21.3 hours) and total influenza-related complications (OR:0.55, 95%CI: 0.42-0.73). Specifically, antivirals significantly decreased bronchitis (OR:0.54, 95%CI: 0.38-0.75), sinusitis (OR:0.51, 95%CI: 0.33-0.78), acute otitis media (OR:0.48, 95%CI: 0.30-0.77), and antibiotic prescription (OR:0.62; 95%CI: 0.48-0.80). A positive trend favored antivirals administration to reduce pneumonia (OR:0.47, 95%CI: 0.16-1.33), or hospitalization rates (OR:0.65; 95%CI: 0.34-1.24) compared to placebo, but did not reach statistical significance. Adverse events (AE) were reported in 11%, 8.9%, and 5.1% of NAIs, placebo and baloxavir recipients, respectively. Compared with NAIs, administration of baloxavir showed non-significantly reduced AEs (OR:0.74, 95%CI: 0.53-1.04). CONCLUSIONS: Single-dose baloxavir and NAIs were superior to placebo to reduce complications in uncomplicated influenza, with 40% significant reduction in antibiotic prescription. Safety and efficacy of single-dose baloxavir were non-inferior to NAIs.

BACKGROUND: Inhaled antibiotics (IA) in non-cystic fibrosis bronchiectasis (NCFB) are recommended by some clinical practice guidelines for prevention or treatment of NCFB exacerbations. METHODS: We performed a systematic review and meta-analysis to evaluate the efficacy and safety of IA use for treatment of adults with NCFB and Pseudomonas aeruginosa chronic bronchial infection. The search was performed in the Cochrane Library, PubMed, and Web of Science databases from 2000 to 2019. Studies of IA for treatment of stable or exacerbated NCFB adults (≥18 years) with P. aeruginosa infection were considered eligible. PROSPERO Registration number: CRD42019136154. RESULTS: Twelve trials (2476 participants) were included. IA therapy increased P. aeruginosa eradication from sputum in patients with exacerbations (OR: 3.19, 95%CI: 1.70-5.99) with similar effects on stable patients (OR: 7.22, 95%CI: 2.81-18.59), and a trend to reduced emergence of new respiratory pathogens (OR: 0.58, 95%CI: 0.28-1.18). IA achieved significant reduced exacerbation rates (RR: 0.90; 95%CI: 0.82-0.98) in stable patients, with a number needed to treat (NNT) of 59, but no significant changes in FEV1, mortality, hospitalizations or quality of life were identified. In stable patients, IA use increased antimicrobial resistance (RR: 2.10, 95%CI: 1.35-3.27) at the end of therapy, with a number needed to treat of 6. CONCLUSIONS: IA therapy achieved a statistically significant eradication of P. aeruginosa from sputum, with a 10% reduction of exacerbations in stable patients. This effect has to be balanced with significant increases in antimicrobial resistance. Our meta-analysis failed to show a significant benefit in terms of patient-centered outcomes.

The Fungal Infections Definitions in Intensive Care Unit (ICU) patients (FUNDICU) project aims to provide standard sets of definitions for invasive fungal diseases (IFDs) in critically ill, adult patients, including invasive aspergillosis (IA), invasive candidiasis (IC), Pneumocystis jirovecii pneumonia (PJP), and other non-IA, non-IC IFDs. The first step of the project was the conduction of separated systematic reviews of the characteristics and applicability to critically ill, adult patients outside classical populations at risk (hematology patients, solid organ transplant recipients) of available definitions and diagnostic tests for IFDs. We report here the results of two systematic reviews exploring the performance of available definitions and tests, for PJP and for other non-IA, non-IC IFDs. Starting from 2585 and 4584 records for PJP and other IFDs, respectively, 89 and 61 studies were deemed as eligible for full-text evaluation. However, only two studies for PJP and no studies for other IFDs met the FUNDICU protocol criteria for inclusion in qualitative synthesis. Currently, there is no sufficient solid data for directly evaluating the performance of existing definitions and laboratory tests for the diagnosis of PJP and other non-IA, non-IC IFDs in critically ill adult patients outside classical populations at risk.
