The spectrum of quality-of-life impairments in recurrent geriatric depression

BACKGROUND: Although recurrent major depression in elderly individuals is a disabling condition, only a few studies have systematically examined the magnitude and specificity of quality-of-life (QOL) impairments in such patients in comparison with matched controls or the elderly population. METHODS: We examined the variations in QOL scores of 100 elderly (age range 60-88 years) patients with moderate to severe recurrent major depression and compared them with published elderly population norms. Disease-specific Quality of Life in Depression Scale (QLDS) and generic Medical Outcomes Short Form-36 Health Survey (SF-36) QOL ratings obtained at baseline were analyzed. RESULTS: Compared with published elderly population norms, depressed subjects showed significant QOL impairments in five of eight baseline SF-36 items (p <.01). Women rated their QOL as worse than men on physical functioning and role physical (p <.01) and showed similar trends on all other QOL items. Compared with younger subjects, subjects aged older than 70 years reported lower QOL on the summary physical component (p <.01) and a trend for higher QOL on the summary mental component (p <.05) of the SF-36. Depression symptom ratings were correlated with some QOL measures, but accounted for less than 10% of the variance. CONCLUSIONS: Despite limitations, such as a cross-sectional design and indirect comparisons with norms generated from another study, our findings confirm the disabling nature of recurrent late-life depression and the importance of targeting both depressive symptoms and broader QOL outcomes in intervention trials.     

Anacetrapib lowers LDL by increasing ApoB clearance in mildly hypercholesterolemic subjects

BACKGROUND. Individuals treated with the cholesteryl ester transfer protein (CETP) inhibitor anacetrapib exhibit a reduction in both LDL cholesterol and apolipoprotein B (ApoB) in response to monotherapy or combination therapy with a statin. It is not clear how anacetrapib exerts these effects; therefore, the goal of this study was to determine the kinetic mechanism responsible for the reduction in LDL and ApoB in response to anacetrapib.METHODS. We performed a trial of the effects of anacetrapib on ApoB kinetics. Mildly hypercholesterolemic subjects were randomized to background treatment of either placebo (n = 10) or 20 mg atorvastatin (ATV) (n = 29) for 4 weeks. All subjects then added 100 mg anacetrapib to background treatment for 8 weeks. Following each study period, subjects underwent a metabolic study to determine the LDL-ApoB-100 and proprotein convertase subtilisin/kexin type 9 (PCSK9) production rate (PR) and fractional catabolic rate (FCR).RESULTS. Anacetrapib markedly reduced the LDL-ApoB-100 pool size (PS) in both the placebo and ATV groups. These changes in PS resulted from substantial increases in LDL-ApoB-100 FCRs in both groups. Anacetrapib had no effect on LDL-ApoB-100 PRs in either treatment group. Moreover, there were no changes in the PCSK9 PS, FCR, or PR in either group. Anacetrapib treatment was associated with considerable increases in the LDL triglyceride/cholesterol ratio and LDL size by NMR.CONCLUSION. These data indicate that anacetrapib, given alone or in combination with a statin, reduces LDL-ApoB-100 levels by increasing the rate of ApoB-100 fractional clearance.TRIAL REGISTRATION.

Radiology of the hand

This is an overview of radiological imaging of the hand highlighting the various imaging modalities used in the work-up and diagnosis of a range of orthopaedic and rheumatological disorders. The biomechanics and anatomy of the human hand is extremely complex, and a good understanding is required to diagnose pathology. In this article we explain the anatomy and highlight pathology of the hand from a radiological perspective with respect to plain film, CT, ultrasound and MR imaging. Trauma of the hand is extremely common and radiology plays an important role in the diagnosis of treatable injuries including fractures, dislocations and ligament tears. Plain radiography and CT are excellent at evaluating bony injury (e.g. Rolondo or Bennett's fracture) whereas ultrasound and MR are better at evaluating soft tissue injury (e.g. Stener lesion). The hands are a common location for degenerate and inflammatory arthropathies which all have hallmark radiological features. Radiology also plays an important role in the diagnosis and work-up of bone lesions in the hand including enchondromas, osteoid osteomas and chondrosarcomas.
