The opportunity costs of caring for people with dementia in Southern Spain

Objective

The aim of this paper is to study the opportunity costs (OC) that are involved in being a caregiver and to compare them with the direct costs assumed by the State and the families. We evaluate direct cost (those that imply a payment-out-of-pocket) and indirect cost (those that imply a dedication in time). We hypothesized that costs increase with the severity of the dementia, with the educational level and active occupational situation of caregiver. They are greater if the caregiver is male, but if the patient and caregiver cohabit they are reduced.

Utility of the PFA-100 as a screening test of platelet function: an audit of haemostasis laboratories in Australia and New Zealand.

The PFA-100 is a relatively new laboratory instrument, first described in 1995. There have since been numerous studies assessing its utility as a screening tool for platelet dysfunction and/or von Willebrand's disease (VWD). The PFA-100 displays variable sensitivity to different types of platelet disorders, as well as to antiplatelet medication (e.g. aspirin), with similar caveats for monitoring of primary haemostasis-promoting therapies in platelet dysfunction. There is therefore considerable uncertainty regarding its utility within this context, and we have accordingly performed an audit of usage among participants of the Royal College of Pathologists of Australasia Quality Assurance Program. Of 105 laboratories surveyed, 40 responded that they performed platelet function testing, with 26 (65%) further indicating they utilized the PFA-100. We report a wide variety of laboratory usage among these users, including numbers of tests performed [annual median (range) = 270 (15-6000)], sources of requests (clinical sources and localities), testing criteria and follow-up action. Most tests were completed within 4 h of collection, as recommended by the manufacturer, and most tests were performed as a replacement, or as a preliminary screen of platelet function (i.e. classical aggregation). Most abnormal findings, however, were attributed to antiplatelet medication such as aspirin.     

Adjuvant chemotherapy in completely resected non-small-cell lung cancer.

Surgery alone has long been the standard treatment for patients with operable non-small-cell lung cancer (NSCLC). However, despite complete resection, 5-year survival rates have been disappointing, with about 50% of patients eventually suffering relapse and death from disease. Randomized trials conducted in the 1980s hinted at a survival benefit for postoperative cisplatin-based regimens, but they were underpowered. A meta-analysis published in 1995 found a nonsignificant 13% reduction in the risk of death associated with cisplatin-based chemotherapy, with an increase of survival of 5% at 5 years. This led to renewed interest in adjuvant chemotherapy in resected NSCLC. Thousands of patients have been included in a new generation of randomized trials in the last 10 years. Most of these recent studies have now been reported and several have demonstrated a clear survival advantage for patients treated with platin-based adjuvant therapy. These results also suggest a greater benefit with modern two-drug regimens. In view of the most recent data, postoperative platin-based chemotherapy can now be considered the standard of care for completely resected NSCLC patients with good performance status.
