The connection between human avian-origin influenza A (H7N9) virus infection and environmental sources of the virus were determined based on clinical data, epidemiology, and virological characteristics of the three early H7N9-infected cases in Hangzhou, Zhejiang Province, China. These H7N9 influenza virus sequences show genomic sequence diversity and key amino acid substitutions, including the novel mammalian-signature substitution Q226I, which is related to human adaptation. This study will be published on Science China Life Sciences 2013, No.6. http://medicalxpress.com/news/2013-05-evidence-host-avian-origin-influenza-virus.html Diseases, Conditions, Syndromes Wed, 15 May 2013 03:05:21 EST news287805662 The most common cause of lower respiratory tract infections in infants and young children, respiratory syncytial virus (RSV), can be transferred during pregnancy to an unborn baby, according to Cleveland Clinic Children's Hospital research published online this week in the journal PLOS ONE. http://medicalxpress.com/news/2013-04-transmission-respiratory-viruses-utero.html Diseases, Conditions, Syndromes Thu, 18 Apr 2013 17:31:44 EST news285525096 A new and deadly virus that has killed 11 of the 17 patients treated for it in the Middle East and Britain appears to cause an infection deep in the lungs, researchers said Wednesday. http://medicalxpress.com/news/2013-04-scientists-monkey-coronavirus-infection.html Diseases, Conditions, Syndromes Wed, 03 Apr 2013 17:00:10 EST news284226711 Among patients with the lung disorder non-cystic fibrosis bronchiectasis, treatment with the antibiotic azithromycin resulted in improvement in symptoms but also increased the risk of antibiotic resistance, according to a study appearing in the March 27 issue of JAMA. http://medicalxpress.com/news/2013-03-azithromycin-benefit-treatment-respiratory-disorder.html Diseases, Conditions, Syndromes Tue, 26 Mar 2013 16:00:11 EST news283523037 The antibiotic clarithromycin – widely used for treating lower respiratory tract infections like pneumonia and acute exacerbations (sudden worsening) of chronic obstructive pulmonary disease (COPD) – may be associated with an increased risk of heart problems, finds a study published in the BMJ today. http://medicalxpress.com/news/2013-03-common-antibiotic-linked-heart-problems.html Medications Thu, 21 Mar 2013 18:30:03 EST news283105043 An important predictor of the severity of respiratory syncytial virus (RSV) in infants may be what their mothers ate during pregnancy, according to a Vanderbilt study published in the American Journal of Respiratory and Critical Care Medicine. http://medicalxpress.com/news/2013-03-maternal-diet-important-predictor-severity.html Diseases, Conditions, Syndromes Mon, 04 Mar 2013 10:04:32 EST news281613862 Pneumonia cannot be accurately diagnosed solely on a doctor's analysis of symptoms and patient history, according to new findings. http://medicalxpress.com/news/2013-01-gp-judgement-accurately-cases-pneumonia.html Diseases, Conditions, Syndromes Wed, 23 Jan 2013 19:00:01 EST news278184257 (HealthDay)—Klebsiella pneumoniae (K. pneumoniae) isolates from U.S. inpatients are becoming increasingly resistant to antimicrobial agents, according to a study published in the January issue of Emerging Infectious Diseases. http://medicalxpress.com/news/2012-12-antimicrobial-resistance-pneumoniae-isolates.html Diseases, Conditions, Syndromes Thu, 20 Dec 2012 12:40:01 EST news275228930 The antibiotic amoxicillin, that doctors typically prescribe for common lower respiratory tract infections (LRTI) such as cough and bronchitis, is no more effective at relieving symptoms than the use of no medication, even in older patients.
