Engaging with change: Information and communication technology professionals' perspectives on change in the context of the 'Brexit' vote.
Information and Communication Technology (ICT) has been a key agent of change in the 21st century. Given the role of ICT in changing society this research sought to explore the responses and attitudes to change from ICT professionals and ICT academics in dealing with the potentially far reaching political challenge triggered by the UK's 2016 European Union Referendum and its decision to leave the European Union (referred to as Brexit). Whilst the vote was a UK based decision its ramifications have global implications and as such the research was not confined to the UK. ⋯ Data was collected through a survey launched on the first working day after the Brexit referendum vote to leave the EU and kept open for four weeks. The survey contained qualitative and quantitative questions. It sought to understand the opportunities and threats that would exist post-Brexit for ICT professionals and academics triggered by the decision. The research captured a complex rich picture on ICT professionals' responses to the potential challenge of change triggered by the Brexit vote. Immediately after the Brexit decision the research reveals uncertainties amongst ICT professionals regarding what the decision would mean, with just under half of the participants not identifying any opportunities or threats. For those who did, threats outweighed opportunities by just more than double. Whilst understanding the global possibilities and dangers, participants saw their position from national and organizational perspectives. The highest frequency coded threats related to areas outside the participants' control and the highest frequency opportunities related to areas where there was the potential for ICT interventions. This survey is part of longitudinal piece of research. Using the same methodological approach two further surveys are planned. The second survey will be one year after Article 50 was triggered on 29 March 2017. The final survey will be one year after the UK exit from the EU, assuming this occurs.

Unpredictable forces which perturb balance are frequently applied to the body through interaction between the upper limb and the environment. Lower limb muscles respond rapidly to these postural disturbances in a highly specific manner. We have shown that the muscle activation patterns of lower limb muscles are organized in a direction specific manner which changes with lower limb stability. ⋯ However, neither the latency nor the magnitude of the response is affected by stiffening the arm even though this alters the magnitude and timing of motion of the body segments. Based on the short latency, insensitivity of the change in ankle muscle activation to motion of the body segments but sensitivity to perturbation direction we reason that changes in ankle muscle activation are most likely triggered by sensory signals originating from cutaneous receptors in the hand. Furthermore, evidence that the latency of changes in ankle muscle activation depends on the number of perturbation directions suggests that the neural pathway is not confined to the spinal cord.

Ethnic differences in non-invasive measurements of carotid atherosclerosis are being increasingly reported, but the association between carotid atherosclerosis and different subtypes of hypertension in adult populations is not fully understood in different ethnicities. We aimed to investigate the association of carotid atherosclerosis with different subtypes of hypertension in different ethnicities in Xinjiang, a northwestern province in China. ⋯ There was an ethnic difference in the prevalence of abnormal CIMT in Xinjiang, a northwestern province in China. The associations between abnormal CIMT and the subtypes of hypertension varied among the different ethnic groups. Among the studied populations, Han participants with SDH, Uygur participants with SDH and ISH, and Kazakh with IDH were more likely to suffer carotid atherosclerosis than those with other subtypes of hypertension. Participants with different ethnic backgrounds had different sets of risk factors for abnormal CIMT.

To evaluate the cost-effectiveness of a quality improvement intervention aimed at reducing maternal and fetal mortality in Accra, Ghana. ⋯ QI interventions to reduce maternal and fetal mortality in low resource settings can be highly cost effective. Cost-effectiveness analysis is feasible and should regularly be conducted to encourage fiscal responsibility in the pursuit of improved maternal and child health.

Dual renin angiotensin system (RAS) blockade using angiotensin-receptor blockers (ARBs) in combination with angiotensin converting enzyme inhibitors (ACEIs) is reported to improve proteinuria in both diabetic and non-diabetic patients. However, its renoprotective effect and safety remain uncertain in patients with advanced chronic kidney disease (CKD). From January 1, 2000 through June 30, 2009, we enrolled 14,117 pre-dialytic stage 5 CKD patients with serum creatinine >6mg/dL and hematocrit <28% under the treatment with erythropoiesis stimulating agents and RAS blockade. ⋯ In comparison with the ARB-only users, dual blockade with ACEIs and ARBs was associated with a significantly higher risk of (1) death in all CKD patients (HR = 1.49, [95%CI, 1.30-1.71]; P = 0.02) and in diabetic subgroup (HR = 1.58, [95%CI, 1.34-1.86]; P = 0.02); (2) composite endpoint of long-term dialysis or death in diabetic subgroup (HR = 1.10, [95%CI, 1.01-1.20]; P = 0.04); (3) hyperkalemia-associated hospitalization in non-diabetic subgroup (HR, 2.74, [95%CI, 1.05-7.15]; P = 0.04). However, ACEIs users were associated with higher mortality than ARBs users in all CKD patients (HR = 1.17, [95%CI, 1.07-1.27]; P = 0.03) and in diabetic subgroup (HR = 1.32, [95%CI, 1.18-1.48]; P = 0.03). Monotherapy of RAS blockade, especially ARB, is more effective and safer than dual RAS blockade in pre-dialytic stage 5 CKD patients.
