Seroprevalence of neutralizing antibodies against respiratory syncytial virus in healthy adults

alexandrossfakianakis shared this article with you from Inoreader Seroprevalence of neutralizing antibodies against respiratory syncytial virus in healthy adults in Guangzhou, southern China Via Journal of Medical Virology Abstract Respiratory syncytial virus (RSV) is the major cause of pneumonia and bronchiolitis in infants and young children, and mediates substantial morbidity and mortality in the elderly and immunocompromised globally. Development a safe and effective RSV vaccine and an optimized neutralizing antibody (NAb) with strong virus-neutralizing activity is appealing. To gain some detailed knowledge on the humoral immune response to RSV subgroup A (RSV-A) and RSV-B, we investigated the seroprevalence of pre-existing NAbs by using the microneutralization assay in healthy adult from Guangzhou, southern China. We found that the overall seropositive rate was 84.86% for anti-RSV NAbs. Furthermore, the seropositive rates were 68.47% and 73.61% for anti-RSV-A NAbs and anti-RSV-B NAbs, respectively. In addition, although the seropositive rates and NAb levels were not associated with the blood type, type AB individuals displaying higher seropositive rates for anti-RSV-A NAbs with hi gh titer (≥ 288) and anti-RSV-B NAbs, especially those with moderate titer (≥ 72-< 288). The seropositive rates and titers were comparable between anti-RSV-A NAbs and anti-RSV-B NAbs in the AB blood type group. Interestingly, only when the NAb titer of the serum to RSV-A was not less than 288, was it not less than 18 to RSV-B, and vice versa. These results would be helpful for a better understanding of the human serum NAb responses to RSV-A and RSV-B. This article is protected by copyright. All rights reserved. View on the web Inoreader.

Usability Experience of a Personal Sleep Monitoring Device to Self-manage Sleep Among Persons 65 Years or Older With Self-reported Sleep Disturbances

alexandrossfakianakis shared this article with you from Inoreader Usability Experience of a Personal Sleep Monitoring Device to Self-manage Sleep Among Persons 65 Years or Older With Self-reported Sleep Disturbances Via Computers Informatics Nursing - Published Ahead-of-Print Increasingly, persons with self-reported health symptoms are using mobile health technologies to better understand, validate, and manage their symptoms. These off-the-shelf devices primarily utilize actigraphy to estimate sleep and activity. The purpose of this study was to describe qualitatively the experience of using a personal sleep monitoring device for sleep self-management in adults 65 years or older with self-reported sleep disturbances. This study followed a hybrid qualitative design using deductive and emergent coding derived from open-ended interviews (n = 25) after a period of 4 weeks using a wearable personal sleep monitoring device. Results expanded existing theoretical models on usability with the theme of personal meaning in the interaction between health and self-monitoring technology that were associated with age and technology use, privacy, and capability. Future studies for sleep health self-management and personally tailored interventions using personal sleep monitoring devices should continue to collect qualitative information in extending the understanding of user experience across different symptom clusters, such as sleep disturbances, that manifest more commonly in older age populations. This research is important for application in the use of mobile health technologies for nursing led health self-management interventions. View on the web Inoreader.
