What is Trip?

Trip is a clinical search engine designed to allow users to quickly and easily find and use high-quality research evidence to support their practice and/or care.

Trip has been online since 1997 and in that time has developed into the internet’s premier source of evidence-based content. Our motto is ‘Find evidence fast’ and this is something we aim to deliver for every single search.

As well as research evidence we also allow clinicians to search across other content types including images, videos, patient information leaflets, educational courses and news.

121. H1N1 Influenza Induced Acute Respiratory Distress Syndrome Rescued by Extracorporeal Membrane Oxygenation: a Case Report (PubMed)

H1N1 Influenza Induced Acute Respiratory Distress Syndrome Rescued by Extracorporeal Membrane Oxygenation: a Case Report Extracorporeal Membrane Oxygenation (ECMO) is now a recognized revolutionary technology, which has emerged as a life-saving therapeutic option for patients with potentially reversible severe respiratory failure who fail to respond positively with the conventional ventilation therapy. Severe acute respiratory distress syndrome (ARDS) is associated with high morbidity (...) and mortality, and ECMO has been proven to increase the survival rates in these patients by improving the gas exchange and thus preventing the further hypoxia and catecholamine induced multi-organ damage. The authors present a case of H1N1 influenza related severe ARDS who was successfully rescued by the early use of ECMO. The authors recommend the early use of ECMO to be incorporated in the management of severe refractory ARDS caused due to a potentially reversible cause.

122. Blockage of regulatory T cells augments induction of protective immune responses by influenza virus-like particles in aged mice (PubMed)

Blockage of regulatory T cells augments induction of protective immune responses by influenza virus-like particles in aged mice Elderly humans over 65 years old are at great risk to pathogenesis by influenza virus infection. However, although influenza vaccines provide effective protection in healthy young adults, protection of elderly adults is substantially lower even with a good match between the vaccine and the circulating influenza virus. To gain insight of the underlying mechanism (...) for the reduced immunogenicity of influenza vaccines in the aged population, we investigated immunogenicity of influenza virus-like particle vaccines in aged mice, which represent a useful model for studying aging associated impairment in immune responses. Specifically, we investigated the effect of inhibiting regulatory T cells in aged mice on induction of protective immune responses by influenza vaccines. Our results showed that injecting anti-CD25 antibodies could down-regulate CD25 on the surface

Influenza Vaccine Effectiveness in the United States during the 2015-2016 Season. The A(H1N1)pdm09 virus strain used in the live attenuated influenza vaccine was changed for the 2015-2016 influenza season because of its lack of effectiveness in young children in 2013-2014. The Influenza Vaccine Effectiveness Network evaluated the effect of this change as part of its estimates of influenza vaccine effectiveness in 2015-2016.We enrolled patients 6 months of age or older who presented with acute (...) respiratory illness at ambulatory care clinics in geographically diverse U.S. sites. Using a test-negative design, we estimated vaccine effectiveness as (1-OR)×100, in which OR is the odds ratio for testing positive for influenza virus among vaccinated versus unvaccinated participants.

Despite the effective treatment available against influenza, it still contributes to significant (...) morbidity and mortality. Currently circulating influenza strains in humans include influenza A (H1N1)pdm09, influenza A (H3N2) and influenza B viruses, (B/Victoria and B/Yamagata).

Haemophilus influenzae oral vaccination for preventing acute exacerbations of chronic bronchitis and chronic obstructive pulmonary disease. Chronic bronchitis and chronic obstructive pulmonary disease (COPD) are serious conditions in which patients are predisposed to viral and bacterial infections resulting in potentially fatal acute exacerbations. Chronic obstructive pulmonary disease is defined as a lung disease characterised by obstruction to lung airflow that interferes with normal (...) breathing. Antibiotic therapy has not been particularly useful in eradicating bacteria such as non-typeable Haemophilus influenzae (NTHi) because they are naturally occurring flora of the upper respiratory tract in many people.

Synergistic effects of influenza and 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) can be eliminated by the use of influenza therapeutics: experimental evidence for the multi-hit hypothesis Central Nervous System inflammation has been implicated in neurodegenerative disorders including Parkinson's disease (Ransohoff, Science 353: 777-783, 2016; Kannarkat et al.

Pulmonary immune cells and inflammatory cytokine dysregulation are associated with mortality of IL-1R1-/-mice infected with influenza virus (H1N1) Respirovirus infection can cause viral pneumonia and acute lung injury (ALI). The interleukin-1 (IL-1) family consists of proinflammatory cytokines that play essential roles in regulating immune and inflammatory responses in vivo. IL-1 signaling is associated with protection against respiratory influenza virus infection by mediation of the pulmonary (...) reduced neutrophil generation in bone marrow and neutrophil recruitment to the inflamed lung. Together, these results suggest that IL-1 signaling is associated with pulmonary anti-influenza immune response and inflammatory lung injury, particularly via the influence on neutrophil mobilization and inflammatory cytokine/chemokine production.
