Communication Disability in Fiji:Community Cultural Beliefs and Attitudes

Purpose: Beliefs about communication disability vary according to the cultural context, and influence people’s attitudes and help-seeking behaviour. Little is known about Fijians with communication disability or the communities in which they live, and specialist services for people with communication disability are yet to be established in Fiji. An understanding of Fijian beliefs about the causes of communication disability and attitudes towards people with communication disability may inform future service development. Method: An interpretivist qualitative research paradigm and the International Classification of Functioning, Disability and Health (ICF) framework informed this project’s design. Scenarios of adults and children with communication disability were presented to 144 participants, randomly sampled across multiple public spaces in two Fiji cities. Thematic analysis of responses to 15 survey questions revealed participant beliefs about the causes and attitudes towards people with communication disability. Results: Three clusters describing perceived causes emerged from the analysis - internal, external, and supernatural. Major clusters across child and adult scenarios were similar; however, response categories within the scenarios differed. Community attitudes to people with communication disability were predominantly negative. These community attitudes influenced individual participants’ beliefs about educational and employment opportunities for Fijians with communication disability. Conclusion: Determination and acknowledgement of individuals’ belief systems informs development of culturally appropriate intervention programmes and health promotion activities. Implications: Speech-language pathologists and other professionals working with Fijian communities should acknowledge community belief systems and develop culturally-specific health promotion activities, assessments, and interventions

Spectrum of mutational signatures in T-cell lymphoma reveals a key role for UV radiation in cutaneous T-cell lymphoma

We performed a meta-analysis of whole exome sequencing data from 403 patients with eight subtypes of T-cell non-Hodgkin’s lymphoma to identify mutational signatures and associated recurrent gene mutations. Signature 1, indicative of age-related deamination, was prevalent across all T-cell lymphomas, reflecting the derivation of these malignancies from memory T-cells. Adult T-cell leukemia-lymphoma was specifically associated with signature 17, which was found to correlate with the IRF4 K59R mutation that is exclusive to Adult T-cell leukemia-lymphoma. Signature 7, implicating UV exposure was uniquely identified in cutaneous T-cell lymphoma (CTCL), contributing 52% of the mutational burden in mycosis fungoides and 23% in Sezary syndrome. Importantly this UV signature was observed in CD4 + T-cells isolated from the blood of Sezary syndrome patients suggesting extensive re-circulation of these T-cells through skin and blood. Analysis of non-Hodgkin’s T-cell lymphoma cases submitted to the national 100,000 WGS project confirmed that signature 7 was only identified in CTCL strongly implicating UV radiation in the pathogenesis of cutaneous T-cell lymphoma

Higher arm versus lower arm systolic blood pressure and cardiovascular outcomes: a meta-analysis of individual participant data from the INTERPRESS-IPD collaboration

Background: Guidelines recommend measuring blood pressure (BP) in both arms, adopting the higher arm readings for diagnosis and management. Data to support this recommendation are lacking. We evaluated associations of higher and lower arm systolic BPs with diagnostic and treatment thresholds, and prognosis in hypertension, using data from the Inter-arm Blood Pressure Difference—Individual Participant Data Collaboration. Methods: One-stage multivariable Cox regression models, stratified by study, were used to examine associations of higher or lower reading arm BPs with cardiovascular mortality, all-cause mortality, and cardiovascular events, in individual participant data meta-analyses pooled from 23 cohorts. Cardiovascular events were modelled for Framingham and atherosclerotic cardiovascular disease risk scores. Model fit was compared throughout using Akaike information criteria. Proportions reclassified across guideline recommended intervention thresholds were also compared. Results: We analyzed 53 172 participants: mean age 60 years; 48% female. Higher arm BP, compared with lower arm, reclassified 12% of participants at either 130 or 140 mm Hg systolic BP thresholds (both P<0.001). Higher arm BP models fitted better for all-cause mortality, cardiovascular mortality, and cardiovascular events (all P<0.001). Higher arm BP models better predicted cardiovascular events with Framingham and atherosclerotic cardiovascular disease risk scores (both P<0.001) and reclassified 4.6% and 3.5% of participants respectively to higher risk categories compared with lower arm BPs). Conclusions: Using BP from higher instead of lower reading arms reclassified 12% of people over thresholds used to diagnose hypertension. All prediction models performed better when using the higher arm BP. Both arms should be measured for accurate diagnosis and management of hypertension.
