Impact of the introduction of the pneumococcal conjugate vaccine in the Brazilian routine childhood national immunization program. Vaccine. 2016 Apr 22; Authors: Moreira M, Cintra O, Harriague J, Hausdorff WP, Hoet B Abstract Brazil introduced the 10-valent pneumococcal non-typeable Haemophilus influenzae protein D conjugate vaccine (PHiD-CV, Synflorix™, GSK Vaccines) in the routine childhood immunization program in 2010 with a 3+1 schedule (with catch-up for children
New Zealand says it will ease its virus measures. Lockdowns return as Europe faces a second wave.
Ontario doctors warn of an "imminent crisis in influenza vaccination" at a time when it's more important that ever that children be immunized.
Authors: Polistina GE, Simioli F, Imitazione P, Lanza M, Annunziata A, Fiorentino G Abstract The coronavirus disease 2019 (COVID-19) is a recent pandemic that affected more than 5 million people worldwide. Chest high resolution computed tomography (HRCT) is an essential tool in diagnosis and management of the disease. Pulmonary parenchymal opacity is a typical sign of the disease, but not the only one. Pneumothorax, pneumomediastinum, bronchiectasis and cysts are probably underrated complications of COVID-19 that can worsen prognosis, in terms of prolonged hospitalization and need of oxygen therapy. In our single c...
Authors: Salvamani S, Tan HZ, Thang WJ, Ter HC, Wa MS, Gunasekaran B, Rhodes A Abstract The COVID-19 disease is caused by the recently identified SARS-CoV-2 virus, thought to have originated in bats (Rhinolophus affinis), the virus being highly infective within the human population and spread by respiratory droplets, contaminated surfaces and close person-to-person contact. The virus is now pandemic and widely disseminated to almost every continent and nation with globally over twenty-seven million infections and over ninety-thousand reported deaths attributed to the COVID-19 disease. SARS-CoV-2 is a single strande...
In this study, we determined the relationship between binding of IgG or IgM and the bacterial survival in normal human serum for 267 invasive H. influenzae strains from Spain, Portugal, and the Netherlands, of which the majority (200 [75%]) were NTHi. NTHi bacteria opsonized with high levels of IgM had the lowest survival in human serum. IgM binding to the bacterial surface, but not IgG binding, was shown to be associated with complement-mediated killing of NTHi strains. We conclude that evasion of IgM binding by NTHi strains increases survival in blood, thereby potentially contributing to their ability to cause severe invasive diseases.
ConclusionsAny difference in price between PHiD-CV and PCV13 is expected to be the key driver of vaccine choice for preventing childhood pneumococcal disease in Turkey. At price parity, PHiD-CV use is likely to be a dominant strategy over the use of PCV13.
CONCLUSION: The results from this study suggest that our NTHi AOM coinfection model is useful for assessing protein vaccines. PMID: 30136923 [PubMed - as supplied by publisher]
CONCLUSION: Non-typeable H. influenzae (NTHi), mostly derived from pneumonia and AOM, were genetically diverse, in contrast to the predominance of H. influenzae type b (Hib) among meningitis cases. The associations between certain STs and β-lactam resistance among NTHi were confirmed. PMID: 29595417 [PubMed - as supplied by publisher]
Authors: K L Ç H, Akyol S, Parkan ÕM, Dinç G, Sav H, Aydemir G Abstract Haemophilus influenzae can cause invasive and severe infections in both adults and children such as otitis media, sinusitis, pneumonia, meningitis and bacteremia. The emerging antibiotic resistance in recent years against ampicillin and several other antibiotics among strains of H. influenzae gives cause for serious concern. Here, we investigate ß-lactamase (BL) activity in clinical isolates of H. influenzae, profile their resistance to antibiotics, and characterize the clonal relationship of the isolates. Antibiotic ...
