Changes in Quality of Life after 3 months of Usual Care in a Large Sample of Patients with Noncancer Pain: The “QOOL: Quality of Life and Pain” Study

Large‐scale observational studies can provide useful information on changes in health outcomes over time. The aim of this study was to investigate the effect of 3 months of usual care on quality of life (QOL) and pain outcomes in noncancer chronic pain patients managed by pain specialists and to examine factors associated with changes in QOL. This was assessed using the EQ‐5D and pain outcomes using the Brief Pain Inventory (BPI). Changes in QOL and pain were studied for the overall sample and in subgroups defined by baseline pain severity. Multivariate regression was used to investigate factors associated with change on EQ‐5D. Three thousand and twenty‐nine patients were included for analysis. After 3 months of usual care, a mean of 40.9% of patients showed improvement on individual EQ‐5D dimensions, with the highest rates of improvement seen on the pain/discomfort (50.8%) and anxiety/depression (48.3%) dimensions. The EQ‐5D Index increased from a mean (SD) of 0.35 (0.2) to 0.58 (0.21) points between baseline and month 3, and the thermometer from 41.5 (19.4) to 58.7 (17.8), indicating a large effect. Improvements in QOL were larger in those with severe baseline pain. The BPI severity summary score improved from a mean (SD) of 6.5 (1.4) to 4.1 (1.7) and the interference summary score from 6.6 (1.5) to 4.2 (1.9). Changes on the BPI severity and interference scores were associated with changes in the EQ‐5D Index and thermometer. In conclusion, 3 months of usual care in noncancer pain patients led to substantial improvements in QOL and pain outcomes.     

Prosthetic joint infection

Total joint replacement has been one of the most remarkable successes of modern medical technology. Once John Charnley had solved the problems of implant design, choice of materials, implant fixation, and infection (initial rates of infection were approximately 10%), the way was clear for the widespread use of this valuable treatment, which is highly effective at removing pain and restoring function. Unfortunately, infection still remains an important, though less common, problem. It is associated with serious morbidity (pain, loss of function, wound breakdown, wound discharge, implant failure) and sometimes mortality. It may be impossible to eradicate or suppress infection in the long term without removal of the prosthesis, and most clinicians would consider it unwise to re-implant a new prosthesis in the presence of infection. Hence, patients with infected prosthetic joints generally require multiple additional operations and prolonged periods of antibiotic therapy. Even radical attempts at cure may fail (in 10% to 15% of cases in most series), requiring further cycles of treatment with progressively deteriorating function. Thus, the treatment of prosthetic joint infection is arduous for the patient and the health care team, with no guarantee of success.     

The friction of explanted hip prostheses

Charnley prostheses, retrieved at revision surgery, were studied to assess the effects of friction on the total hip replacement procedure. Frictional resistance was measured using the Durham hip function simulator under both dry and lubricated conditions. The friction factor values (f) for the explanted prostheses were found to have a non- Gaussian distribution with medians of 0.13 [inter-quartile range (IQR) 0.10-0.16] and 0.06 (IQR 0.005-0.08) for dry and lubricated (n = 0.01 Pa s) regimes, respectively. New Charnley prostheses had values of f equal to 0.11 +/- 0.025 and 0.04 +/- 0.01 under the same conditions, and showed no large deviation from a Gaussian distribution. There was found to be a statistically significant difference in the medians of the friction factors for new and retrieved prostheses in the lubricated regime. Ingression of cement into the worn region of the cup was found to increase the friction factor significantly under dry conditions. There was no evidence of an increase in the friction factor or torque for those joints that had a loose socket with respect to those that were fixed at revision. A decrease in the frictional torque against number of cycles undergone by the joint in vivo may indicate that a fatigue-type process may have a role in the loosening of the socket. However, this relationship was found not to be significant for friction measured under lubricated conditions and it seems unlikely that the frictional torque generated in this type of prosthesis will contribute significantly to the long-term loosening of the socket.      

Maintaining dignity for residents of care homes: A qualitative study of the views of care home staff,community nurses,residents and their families

This study uses the Framework approach to qualitative analysis to explore and compare the views of residents in care homes for older people, their families and care providers on maintaining dignity. We interviewed 33 care home managers, 29 care assistants, 18 care home nurses, 10 community nurses, 16 residents and 15 members of residents' families. The most prevalent themes were: “independence,” and “privacy”; followed by “comfort and care,” “individuality,” “respect,” “communication,” “physical appearance” and “being seen as human.” Residents and their families sometimes described incidents where a resident's dignity had been compromised. How to help residents maintain dignity and focusing on fostering dignity, can be a starting point for improving the quality of care and quality of life of residents. It is, however, important to remove the gap between the rhetoric of dignity conserving care and the reality experienced by residents in these and other care settings.     

Echocardiographic Screening for Subclinical Rheumatic Heart Disease Remains a Research Tool Pending Studies of Impact on Prognosis

Paravalvular regurgitation (PVR) is a symptomatic or asymptomatic complication after surgical valve replacement. It may be related to calcification, infection or tissue friability and occurs in 5 % to 17 % of surgical implanted heart valves. Reoperation is associated with a higher morbidity and mortality than the index procedure. Percutaneous closure of PVR can be an effective and lower risk alternative to reoperation. However, feasibility for percutaneous closure has to be assessed by defining the shape, size and location of the defect. Echocardiography with three-dimensional defect reconstruction is a cornerstone for guiding percutaneous PVR closure. Access for aortic PVR is usually retrograde via the femoral artery and access to mitral PVR either retrograde from the aorta, transvenous-transseptal or transapical. Meticulous planning and prudent procedural execution by experienced operators ensuring no impingement of the prosthetic leaflets leads to a high success rate of percutaneous PVR repair.     

The Pan-African Society of Cardiology (PASCAR) in 2013 and beyond

Abstract

The biennial Congress of the Pan-African Society of Cardiology (PASCAR) was held in Dakar from 16 to 19 May 2013 under the patronage of his Excellency, Macky Sall, president of the Republic of Senegal. This meeting was remarkable in the diversity of its 700 participants from English-, French- and Portuguese-speaking Africa. Important aspects of cardiovascular disease in Africa were presented in 195 abstracts and numerous talks; the topics were hypertension, obesity, diabetes, heart failure, cardiomyopathies, coronary heart disease, stroke and rheumatic heart disease. The general assembly meeting was marked by the review and adoption of a new constitution and elections of a new PASCAR governing council that will be in office for the next four years. The new leadership of PASCAR has committed itself to strengthening the administrative infrastructure of the organisation, developing programmes to address education and training needs of African cardiovascular practitioners, developing a pan-African multi-national research platform, and ensuring that ministries of health implement national programmes for the prevention and control of cardiovascular and other non-communicable diseases.
