Life activity choices by people with aphasia: repeated interviews and proxy agreement

Background: Person-centered rehabilitation requires that meaningful life activities are identified on a case-by-case basis, but the discovery process can be inaccessible for clients with aphasia. Card-sorting methodology addresses core barriers and help clients communicate their preferences.

Aims: To characterize life activities that people with aphasia want to do, to estimate consistency in selections over time, and to replicate previous findings about the ability of family members and friends to identify their loved ones’ activity preferences.

Methods & Procedures: We administered the Life Interests and Values (LIV) Cards to 26 people with aphasia, asking them which of 95 depicted life activities they wanted to do more in their lives. Half the activity cards were presented again one to ten weeks later. Twenty family members or friends responded as proxies by selecting from a questionnaire with the same items.

Outcomes & Results: Participants with aphasia selected diverse activities, though as a group they identified significantly more activities from the “social” activity category than from the “home and community”, “creative and relaxing”, or “physical” categories. Across the repeated interviews, they selected identical activities on average 78% of the time. Item-to-item agreement between people with aphasia and their proxy responders was significantly lower at 69%.

Conclusions: People with aphasia have diverse activity interests and are reliable informants about their preferences. Because significant others have limited ability to predict these choices, their impressions are inadequate substitutes for direct interviews.

Recurrent respiratory papillomatosis in northern Sweden: Clinical characteristics and practical guidance

Conclusion: Recurrent respiratory papillomatosis (RRP) patients with high surgical treatment frequency (≥ 1/year, HF) were significantly younger and had a more widespread laryngeal disease compared to a low frequency treated group (< 1 treatment/year, LF). This study confirms the existence of a clinical RRP group, not primarily related to HPV sub-type, but more care-intensive and in need of more vigilant follow-up. Objectives: RRP is associated with high morbidity due to its influence on breathing and voice. The purpose of this study was to characterize RRP patients in northern Sweden and investigate possible predictor factors affecting therapeutic needs. Method: Patients from the regional referral area (northern Sweden) were categorized for age, disease duration, juvenile or adult onset, profile of disease development, number of surgical sessions in relation to disease duration, laryngeal deposition of papilloma, gender, and HPV sub-types, in order to identify patients with increased need for frequent surgical treatment. Results: The median age of the RRP patients (n = 48) was 44.5 years; 34 (71%) were males and 14 (29%) females, most were infected with HPV 6. Patients with high surgical treatment frequency/year were significantly younger and showed more widespread papillomatous vegetation in the larynx, compared to the low frequency treated group.     

Central nervous system-infiltrated immune cells induce calcium increase in astrocytes via astroglial purinergic signaling

Interaction between autoreactive immune cells and astroglia is an important part of the pathologic processes that fuel neurodegeneration in multiple sclerosis. In this inflammatory disease, immune cells enter into the central nervous system (CNS) and they spread through CNS parenchyma, but the impact of these autoreactive immune cells on the activity pattern of astrocytes has not been defined. By exploiting naïve astrocytes in culture and CNS-infiltrated immune cells (CNS IICs) isolated from rat with experimental autoimmune encephalomyelitis (EAE), here we demonstrate previously unrecognized properties of immune cell–astrocyte interaction. We show that CNS IICs but not the peripheral immune cell application, evokes a rapid and vigorous intracellular Ca²⁺ increase in astrocytes by promoting glial release of ATP. ATP propagated Ca²⁺ elevation through glial purinergic P2X7 receptor activation by the hemichannel-dependent nucleotide release mechanism. Astrocyte Ca²⁺ increase is specifically triggered by the autoreactive CD4⁺ T-cell application and these two cell types exhibit close spatial interaction in EAE. Therefore, Ca²⁺ signals may mediate a rapid astroglial response to the autoreactive immune cells in their local environment. This property of immune cell–astrocyte interaction may be important to consider in studies interrogating CNS autoimmune disease.
