Post-polio syndrome--polio's legacy

Growing older with post-polio syndrome: Social and quality-of-life implications

Objectives

To understand the quality-of-life implications for post-polio syndrome survivors.

Methods

For this qualitative study, a focus group methodology, with a case study design, was used. The data were analyzed for themes using a social ecological conceptual framework.

Results

Three focus groups were conducted with a total of 24 participants (N = 24). Participants defined quality of life as being able to engage in meaningful activities of daily living. Participants shared experiences of adapting to declining physical health and embracing new activities of daily living. They expressed hope and shared stories that demonstrated resiliency.

Conclusion

The literature states that individuals aging with post-polio syndrome express concern that health providers often know little about their disability condition. The participants in this study reflected this experience by sharing feelings of misunderstanding from the medical community and expressing a desire to have more dynamic education for health providers.

A Patient as Art: Andrew Wyeth's Portrayal of Christina Olson's Neurologic Disorder in Christina's World

In Christina's World, one of the most beloved works of American art, Andrew Wyeth painted Christina Olson crawling crablike across the field below her house, raised on emaciated arms, with a swollen knob for an elbow, and hands clenched and gnarled. The significance of these physical abnormalities, and the message Wyeth endeavored to convey via the portrait, are considered here in light of Christina's medical history and the disorder it most likely signifies.

Public awareness regarding children vaccination in Jordan

Immunization can contribute to a dramatic reduction in number of vaccine-preventable diseases among children. The aim of this study is to investigate mothers' awareness about child vaccines and vaccination in Jordan. This study was a community-based, cross-sectional study that was performed at public places in Irbid City. Data was collected from 506 mothers. After verbal approval, mothers were interviewed to assess their knowledge, attitudes, and practice toward vaccination. Results show that majority of mothers had acceptable knowledge and positive attitude toward vaccination. Most of mothers (94.7-86.8%) were able to identify vaccines that are mandatory as per the national vaccination program. Lower knowledge was observed among mothers (71.6%) for HIB vaccination being mandatory. Most mothers (97.2%) had vaccination card for their baby form the national vaccination programs. Vaccination delay was reported by about 36.6% of mothers and was shown to be associated with significantly (P = 0.001) lower vaccination knowledge/attitude score. Additionally, mothers who reported to be regularly offered information about vaccination during visits and those who identified medical staff members as their major information source had significantly higher vaccination knowledge/attitude score (P = 0.002). In conclusion, vaccination coverage rate is high; however, some aspects of knowledge, attitudes, and practice of vaccination need to be improved. Knowledge and attitudes of mothers were directly associated with their practice of vaccination. Medical staff education about vaccination during each visit seems to be the most effective tool that directly reflects on better practice of vaccination such as reducing the possibility for vaccination delay.

Human astrocytic cells support persistent coxsackievirus B3 infection

Enteroviruses can frequently target the human central nervous system to induce a variety of neurological diseases. Although enteroviruses are highly cytolytic, emerging evidence has shown that these viruses can establish persistent infections both in vivo and in vitro. Here, we investigated the susceptibility of three human brain cell lines, CCF-STTG1, T98G, and SK-N-SH, to infection with three enterovirus serotypes: coxsackievirus B3 (CVB3), enterovirus 71, and coxsackievirus A9. Persistent infection was observed in CVB3-infected CCF-STTG1 cells, as evidenced by prolonged detection of infectious virions, viral RNA, and viral antigens. Of note, infected CCF-STTG1 cells expressed the nonfunctional canonical viral receptors coxsackievirus-adenovirus receptor and decay-accelerating factor, while removal of cell surface chondroitin sulfate from CCF-STTG1 cells inhibited the replication of CVB3, suggesting that receptor usage was one of the major limiting factors in CVB3 persistence. In addition, CVB3 curtailed the induction of beta interferon in infected CCF-STTG1 cells, which likely contributed to the initiation of persistence. Furthermore, proinflammatory chemokines and cytokines, such as vascular cell adhesion molecule 1, interleukin-8 (IL-8), and IL-6, were upregulated in CVB3-infected CCF-STTG1 cells and human progenitor-derived astrocytes. Our data together demonstrate the potential of CCF-STTG1 cells to be a novel cell model for studying CVB3-central nervous system interactions, providing the basis toward a better understanding of CVB3-induced chronic neuropathogenesis.
