Merkel Cell Polyomavirus DNA in Respiratory Specimens from Children and Adults
Merkel cell polyomavirus (MCPyV) DNA was detected in 7 (1.3%) of 526 respiratory tract samples from patients in Australia with upper or lower respiratory tract symptoms. Partial T antigen and major capsid protein sequences of MCPyV identified in respiratory secretions showed high homology (99%–100%) to those found in Merkel cell carcinoma
Novel Respiratory Virus Infections in Children, Brazil
Recently discovered respiratory viruses were detected in 19 (9.2%) of 205 nasal swab specimens from children in Brazil with respiratory illnesses. Five each were positive for human metapneumovirus (HMPV) alone and human bocavirus (HBoV) alone, 3 for human coronaviruses (HCoV-HKU1 or -NL63) alone, and 6 for more than 1 recently discovered virus
Adapted cardiac rehabilitation programme to improve uptake in patients of Moroccan and Turkish origin in The Netherlands:a qualitative study
Aim. To explore the treatment experiences in patients of Moroccan and Turkish origin and their rehabilitation therapists regarding an adapted outpatient cardiac rehabilitation programme. Background. Non-native patients who participated in a cardiac rehabilitation programme at a Dutch rehabilitation centre had more difficulties to achieve the treatment aims than native Dutch patients. Therefore, an adapted programme for non-native patients, lacking proficiency in Dutch, has been instigated. The programme contains six adapted treatment modules and additional strategies: adapted education regarding (1) the heart and the vascular system and (2) the use of healthy food, with use the of (audio) visual educational materials, (3) adapted physical exercise module with explicit involvement of the patients relatives, (4) standard use of professional interpreters, (5) increase in the number and length of consultations and (6) individual treatment instead of a group programme. Design. Qualitative study. Method. Semi-structured, face-to-face interviews were conducted with eight patients of Moroccan and Turkish origin and five native Dutch rehabilitation therapists. By comparison, three native Dutch patients were interviewed regarding the regular programme. Results. The results indicate that the patients disease symptoms reduced and that patients adopted lifestyle changes. Therapists experienced that the number and length of the consultations, the structural use of interpreters and (audio) visual educational materials contributed to the achievement of the treatment aims. Conclusion. An adapted cardiac rehabilitation programme with separate modules and additional strategies for non-native patients appears to lead to satisfied patients who adopted lifestyle changes. Relevance to clinical practice. The findings of this study are important as the study highlights the practical actions that may be taken by physicians and healthworkers to adjust rehabilitation treatment to the needs of patients of non-native origin
Comparison of test specificities of commercial antigen-based assays and in-house PCR methods for detection of rotavirus in stool specimens
Seven commercial rotavirus antigen assays were compared with in-house PCR methods for detecting rotavirus in stool specimens. The assay sensitivities were 80% to 100%, while the specificities were 54.3% for one commercial immunochromatographic (ICT) method and 99.4% to 100% for other assays. Thus, except for one commercial ICT, all the assays were generally reliable for rotavirus detection
Symptom complexes in patients with seropositive arthralgia and in patients newly diagnosed with rheumatoid arthritis: a qualitative exploration of symptom development
Objective: The aim of this study was to explore symptoms and symptom development during the earliest phases of rheumatoid arthritis (RA) in patients with seropositive arthralgia and patients newly diagnosed with RA
Evidence of false-positive results in a commercially available rotavirus assay in the vaccine era, Australia, 2011 to 2012
Concerns were raised about specificity of the VIKIA Rota-Adeno immunochromatographic kit. Only 28-37% of samples positive with the VIKIA kit could be confirmed using two real-time RT-PCR assays and three ELISA kits. On re-analysis of a subset of the positive samples, 86% remained positive with the VIKIA kit, however, 90% remained negative in the other assays. In a highly vaccinated population we found a high number of false-positive rotavirus tests with a widely-used commercial kit
Usefulness of Published PCR Primers in Detecting Human Rhinovirus Infection
We conducted a preliminary comparison of the relative sensitivity of a cross-section of published human rhinovirus (HRV)–specific PCR primer pairs, varying the oligonucleotides and annealing temperature. None of the pairs could detect all HRVs in 2 panels of genotyped clinical specimens; >1 PCR is required for accurate description of HRV epidemiology
Viruses causing lower respiratory symptoms in young children: Findings from the ORChID birth cohort
© 2018 Article author(s). Introduction Viral acute respiratory infections (ARIs) cause substantial child morbidity. Sensitive molecular-based assays aid virus detection, but the clinical significance of positive tests remains uncertain as some viruses may be found in both acutely ill and healthy children. We describe disease-pathogen associations of respiratory viruses and quantify virus-specific attributable risk of ARIs in healthy children during the first 2 years of life. Methods One hundred fifty-eight term newborn babies in Brisbane, Australia, were recruited progressively into a longitudinal, community-based, birth cohort study conducted between September 2010 and October 2014. A daily tick-box diary captured predefined respiratory symptoms from birth until their second birthday. Weekly parent-collected nasal swabs were batch-tested for 17 respiratory viruses by PCR assays, allowing calculation of virus-specific attributable fractions in the exposed (AFE) to determine the proportion of virus-positive children whose ARI symptoms could be attributed to that particular virus. Results Of 8100 nasal swabs analysed, 2646 (32.7%) were virus-positive (275 virus codetections, 3.4%), with human rhinoviruses accounting for 2058/2646 (77.8%) positive swabs. Viruses were detected in 1154/1530 (75.4%) ARI episodes and in 984/4308 (22.8%) swabs from asymptomatic periods. Respiratory syncytial virus (AFE: 68% (95% CI 45% to 82%)) and human metapneumovirus (AFE: 69% (95% CI 43% to 83%)) were strongly associated with higher risk of lower respiratory symptoms. Discussion The strong association of respiratory syncytial virus and human metapneumovirus with ARIs and lower respiratory symptoms in young children managed within the community indicates successful development of vaccines against these two viruses should provide substantial health benefits
