Patients with lupus anticoagulant and anticardiolipin antibodies are at risk of throm boem bolic events, including renal graft vein or artery throm bosis. These patients m ay require anticoagulation therapy, or platelet inhibi- tion with aspirin.

N ineteen cases of de novo or recurrent M CGN after transplantation have been described in patients with Clinical: hepatitis C virus (HCV). Almost all had nephrosis and exhibited Proteinuria sym ptom s 2 to 120 m onths after transplantation. Eight patients had dem onstrable cryoglobulin, nine had hypocom plem entem ia, Nephrotic syndrome and m ost had norm al liver function test results.

Prognosis in these patients was poor, with persistent heavy proteinuria and declining renal function. The overall recurrence rate is approximately 20% to 30% [1,4,31]. These numbers, however, may be an underestimate because of biopsy sampling errors. Patients Risk factor Recurrence rate, % at high risk for recurrence can be identified, particularly children with rapid evolution of their original disease and mesangial expansion Age <5 y 50 on biopsy [1,32]. Recurrence m anifests with proteinuria (often Age < 15 y with progression to end-stage renal disease 80–100 10–40 g/d), developing hours to weeks after transplantation. In within 3 y children the m ean tim e to recurrence is 14 days.

What do universal health coverage and social protection mean for people afected by tuberculosis? Tuberculosis (TB) is a disease of poverty that drives people deeper into poverty (22). In recognition of this fact, TB diagnosis and treatment are free of charge for patients in most countries. The cost of TB treatment, provided as a public service, is covered by domestic health-care budgets, often supplemented by international grants or loans (23). This helps to reduce the financial barriers to accessing and adhering to treatment. However, free public health services are often not entirely free, and patients always face other expenses. Payments are made for medical tests, medicines, consultation fees and transport, and there are indirect costs of illness due to lost earnings. For patients, therefore, the total cost of an episode of TB is often large in relation to their income (24). The aver- age total cost incurred by TB patients in low- and middle-income countries has been estimated at between 20% and 40% of annual family income, and the relative cost is higher in the lower socioeconomic groups (25–32). The poorest patients become indebted: 40−70% of them according to three studies carried out in Africa and Asia (26, 28, 29). A large part of the cost of TB treatment is incurred during the diagnostic phase before treatment starts in a subsidized TB programme. Costs are especially high for diagnosis and treatment by private doctors, with whom many of the very poorest seek care first (28, 29, 33, 34). Financial costs are commonly compounded by adverse social consequences – such as rejection by family and friends, divorce, expulsion from school and loss of employment – which affect women in particular (35–37). The research behind these findings has been essential for documenting the obstacles to the use of health services and the financial vulnerability of families affected by TB. It has helped to pinpoint where improved services, health insurance coverage and social protection can safeguard against the consequences of potentially fatal and financially catastrophic illness (38). The results have begun to inform national policy on social protection for people with TB (39, 40). Beyond free diagnosis and treatment, a full package of measures for social protection requires the following: ■ Universal health care, free of cost, or heavily subsidized. People do not enter the health-care system as TB patients eligible for free treatment; they typically enter as patients with a respiratory illness. The journey to correct diagnosis and the start of treatment often takes weeks or months. Out-of-pocket expenses need to be minimized across the health system (23). For example, these may include travel vouchers, food packages, or cash transfers, as well as psychosocial support. Poverty-reduction strate- gies and financial safety nets help prevent TB on many levels. Most important for TB prevention are good living and working conditions and good nutrition. Basic education supports universal health coverage by enabling healthy lifestyle choices and informing health-care decisions. While disease-specific solutions can help partly and tempo- rarily, universal health coverage, including social protection, is vital for sustained and effective TB control. Disease control programmes need to ensure that the patients they serve are eligible for, and actually receive, support from the general health services and not only from TB control programmes. TB has close links with poverty and social vulnerability, and is one of the conditions that can function as a tracer for universal coverage. However, national TB control programmes need to add measures of financial risk protection to existing indicators of service coverage.

However, a recent study found that although PPT porin can be used to destroy the cholinergic innervation of 8 Neuropsychopharmacology: The Fifth Generation of Progress conditioning but impairments in discrete cue (trace) condi- tioning (69). Both sets of data may suggest that the atten- tional processing of discrete stimuli is disrupted following cholinergic depletion from posterior cortical regions. It is possible, however, that the depletion of ACh from caudal or rostral cortical regions alone may be insufficient to impair performance of some tasks, whereas combined depletions may have more than additive effects (70). Other investigators have further argued that the choliner- gic innervation of rostral (e. Direct pharmacologic manipulation of basal forebrain neurons has been used to alter activated cholinergic efflux in the frontal cortex and performance of tasks related to stimulus process- ing or detection (72). Selective excitotoxic lesions or phar- macologic manipulation of the nucleus basalis has also been reported to impair performance in a five-choice serial reac- tion task that requires animals to detect and respond to brief visual stimuli (73). Interestingly, the observation that appetitive pavlovian learning for a discrete cue is enhanced after nucleus basalis lesions (74) suggests that attentional processing of discrete cues may not be affected by depletion of ACh from the rostral neocortex except when divided attention is required. The findings of these latter studies are also bolstered by advances in the measurement of ACh FIGURE 1. Acetylcholinesterase staining of the nucleus basalis magnocellularis after infusion of saline solution or AMPA to de- transmission in vivo, which allows investigators to quantify stroy cholinergic neurons preferentially. Low concentrations of directly the extent of the lesions produced by the toxins for the glutamatergic agonist AMPA selectively destroy cholinergic the first time (75). Taken together, the available data seem neurons (measured by acetylcholinesterase staining) and spare -aminobutyric acid (GABA) neurons (left). In contrast, control to suggest that basal forebrain cholinergic neurons are capa- sections show robust acetylcholinesterase staining after infusion ble of regulating the cortical processing of sensory stimuli of saline solution (right). This process allows more specific cholin- within a variety of domains, which may be explained by a ergic lesions to be generated, so that the function of the neurons role for basal forebrain ACh in the regulation of cortical in behavioral processes can be clarified.
