Screening for atrial fibrillation within a South Asian community setting using single-lead ECG
No full textTimely detection and treatment of AF is amongst the Government’s cardiovascular priorities. Several initiatives have demonstrated the potential of AF detection using single-lead electrocardiogram (SLECG) technology in primary care settings, such as general practitioners’ (GP) surgeries. Unfortunately, some AF patients, including those from ethnic minorities, may not routinely engage with main-stream healthcare and may go undetected. Compared to White British, South Asians have a higher prevalence of cardiovascular risk factors, however fewer are diagnosed with AF. This study aimed to ascertain the feasibility of opportunistic AF screening within a South Asian community delivered by supervised pharmacy undergraduates using SL-ECG devices
Clinical predictors of atrial fibrillation recurrence in the Gruppo Italiano per lo Studio della Sopravvivenza nell'Infarto Miocardico-Atrial Fibrillation (GISSI-AF) trial
No full textBackground - Atrial fibrillation (AF) is a common arrhythmia that frequently recurs after restoration of sinus rhythm (SR). Identifying risk factors for recurrence may help define the best strategy for secondary prevention. Methods - The GISSI-AF trial enrolled 1,442 patients in SR with at least 2 documented AF episodes in the previous 6 months or after cardioversion in the last 2 weeks. Patients were randomized to valsartan or placebo; all other treatments for AF or underlying heart diseases were allowed. Primary end points were time to first recurrence of AF and proportion of patients with >1 AF episode during 1-year follow-up. We evaluated clinical and electrocardiographic baseline characteristics of all patients to identify independent predictors for AF recurrence using a Cox multivariable model. Results - Risk factors for AF recurrence were a history of 2 or more AF episodes in the previous 6 months, independent of the modality of SR restoration, spontaneous (HR 1.42, 95% CI 1.14-1.77, P = .002), or by cardioversion (HR 1.19, 95% CI 1.01-1.40, P = .038), and a lower heart rate during SR (HR 0.99, 95% CI 0.99-1.00, P = .052). The risk factors were the same for > 1 AF recurrence. Patients treated with amiodarone had a lower risk for both end points (P < .0001 and P = .017), whereas those on diuretics had a greater risk (P = .009 and P = .003). Conclusions - In the GISSI-AF study population, AF history had significant prognostic value independent of the modality of SR restoration. Amiodarone and diuretic treatment affected the rate of AF recurrence
Pharmacists detecting atrial fibrillation (PDAF) in primary care during the influenza vaccination season: a multi-site, cross sectional feasibility pilot study
No full textReducing AF-related stroke risk is both clinically and economically important, with AF-related illness costing the NHS over £2 billion per annum. Despite this, there is no national screening programme for AF. Growing medical consensus backed by public health policy, agrees that there is an unmet need to improve diagnosis and that primary care is an appropriate setting. This model is likely to be convenient for patients and cost effective, but with the current shortage of GPs and nurses, and increasing GP workloads, it is unlikely to succeed. Huge investment by NHS England to introduce new work role models to GP practices, could mean, by 2021, that over 34 million patients will have access to the expertise of a clinical pharmacist, making clinical pharmacists a viable option for such screening initiatives. AIM: To determine whether clinical pharmacists based within GP practices, were able to accurately and effectively screen and diagnose patients for AF, using pulse palpation and a single-lead ECG device (AliveCor Kardia Mobile®) during the influenza vaccination season

An illness-specific version of the Revised Illness Perception Questionnaire in patients with atrial fibrillation (AF IPQ-R): Unpacking beliefs about treatment control, personal control and symptom triggers
No full textThis study modified the Revised Illness Perception Questionnaire (IPQ-R) in patients with persistent Atrial Fibrillation (AF). Qualitative interviews and think-aloud techniques informed modification of the IPQ-R to be specific to AF patients. Confirmatory Factor Analysis (CFA) (n=198) examined the validity of the modified IPQ-R (AF-IPQ-R). Exploratory Factor Analysis (EFA) examined the new AF-triggers scale. Construct validity examined associations between the AF-IPQ-R, quality of life (QoL) and beliefs about medicines. Test-retest and internal reliability were examined. Interviews indicated that patients viewed triggers of AF rather than initial causes of illness as more applicable. Patients believed specific behaviours such as rest could control AF. Treatment control beliefs related to pharmacological and procedural treatments. These data were used to modify the IPQ-R subscales and to develop a triggers of AF scale. CFA indicated good model fit. EFA of the triggers scale indicated 3 factors: emotional; health behaviours; and over-exertion triggers. Expected correlations were found between the AF-IPQ-R, QoL and treatment beliefs, evidencing good construct validity. The AF-IPQ-R showed sound psychometric properties. It provides more detailed specification than the IPQ-R of beliefs that may help to understand poor QoL in AF patients, and guidance for future interventions in this area

Surgical treatment for metastatic pathological fractures.
No full textPathological fractures of the long bones occur in 10–29% of patients with bone metastases. The occurrence of these fractures may alter management and prognosis, decrease quality of life and jeopardize survival [1–4]. The fracture hematoma may contaminate the adjacent soft tissue, nerves, vessels and joint, and damage to the microcirculation may favor distant hematogenous dissemination of the tumor [5]

In spite of, the somali language problem is recognisable in some others factors: lack of state that usually chooses somali language as official language, extinction of many terms in disuse and also the strong influence of English.Cabdirashid M.
