We then explored the impact of scaling this effect to the magnitude of the pooled mean reduction in PWV (1 cholesterol levels when to take medication crestor 10 mg low cost. We also explored the impact of applying it to the all-cause mortality rate in the model normal cholesterol levels nz buy genuine crestor. These analyses should be treated with caution cholesterol kit cvs crestor 20 mg order free shipping, as they rely on cross-sectional associative evidence from an observational study to inform possible effects of bioimpedance monitoring. It should be further noted that the pooled estimate for the effect of bioimpedance monitoring on PWV is non-significant and based on results from only two trials, showing inconsistent results (see Figure 7). However, the point estimate is applied in the base-case model and the uncertainty surrounding it is 40 NIHR Journals Library www. Furthermore, the negative interaction between increasing AAC tertiles and the effect of baseline PWV on mortality and CV event-related hospitalisation, suggests that the relative effect of reductions in PWV may be greater in lower-risk groups (with lower AAC scores). On the other hand, evidence for an interaction in the prognostic value of baseline measures of these two variables does not necessarily mean that the AAC score would modify the effect of an intervention-induced reduction in PWV. Therefore, this model could potentially over- or underestimate the likely effects of the estimated reduction in PWV on final health outcomes. Better evidence on the effects of intervention-induced reductions in PWV are required to inform this issue. As an alternative approach to indirectly estimate possible effects of bioimpedance-guided fluid management on mortality and CV event-related hospitalisation, we considered linking the estimated pooled reduction in SBP (2. Assuming a log-linear relationship between SBP reduction and the relative risk of events, these effects can be rescaled to the mean reduction in SBP across included BCM trials (2. These effects are substantially larger than the estimated effects using PWV above, and suggest a potentially larger effect on CV events than on all-cause mortality. However, it is uncertain if effects on SBP induced by blood pressure medication can be generalised to potential reductions in SBP induced by the management of fluid status, that is, some blood pressure medications are thought to have effects on CV events that are independent of their blood pressure-lowering effects. Nevertheless, the effect of bioimpedance-guided fluid management on SBP (bordering on significance), suggests a possible beneficial effect on both CV events and mortality. Therefore, we explored the impact of applying larger and differential relative effects on these outcomes in further scenario analyses.

ASSESSMENT OF COST-EFFECTIVENESS Finally, we also explored the impact of using associations between overhydration and all-cause mortality and hospitalisation rates to drive effects in the model. This analysis assumed that for everyone who is moved from the overhydrated (relative fluid overload > 15%) to the normally hydrated state, the increased risks associated with overhydration are completely reversed. This was an optimistic assumption, as, again, cross-sectional associations between baseline measures and final outcomes were used to drive the effects of bioimpedance-guided fluid management in the model. The increased risk associated with baseline overhydration may not be fully reversible for those that can be returned to normal hydration status (≤ 15%). A further problem with this approach is the lack of reporting in the RCTs on the effect of bioimpedance- guided fluid management on the proportion of patients with pre-dialysis ROH of > 15% at baseline and follow-up. Yet, the study did demonstrate a significant effect on PWV and mortality, leading the authors to speculate that the mechanism for effect may be as much a result of the avoidance of chronic underhydration as overhydration. We used these data to approximate percentage reductions in ROH of > 15% (absolute overhydration of > 2. This yielded plausible percentage reductions in ROH of > 15% from 28% to 38% with bioimpedance-guided management relative to control. These were applied in model scenarios utilising the change in ROH status to drive effects on all-cause mortality and all-cause hospitalisation. Further hypothesised benefits of bioimpedance-guided fluid management that were not incorporated in the main analyses included changes in quality of life (independent of effects on hospitalisation and CV events), maintenance of residual renal function and effects on dialysis requirements (number and duration of sessions). None of the identified BCM trials reported on health-related quality of life, and only one included any patient-reported outcomes. This showed that reductions in absolute overhydration (per litre) between baseline and 12 months were associated with improvements in the physical component score (1. These analyses were adjusted for various potential confounders, including age, sex, dialysis vintage, haemoglobin level, baseline overhydration status and comorbidities (as measured by the Charlson Comorbidity Index). Although this study suggests that use of the BCM could lead to improvements in heath-related quality of life (independent of effects on adverse events), it is not clear how generalisable the reported changes are to the UK population.

The impact of universal coverage schemes in the developing world: a review of the existing evidence. Key points ■ Chapter 1 considered ways of measuring the gap between the present coverage and universal coverage of health services. The question of how to fill that gap is a target for research in every country. Research for universal health coverage, underpinned by research for health, is the body of methods and results used to find new ways of providing the health care needed by everyone. They come from both within the health sector and beyond it and will flourish wherever they are permitted and encouraged to do so. The growth is uneven, but most countries now have the foundations on which to build effective research programmes. One example is new thinking to break the mould of traditional research and development (R&D), where more products are being created through partnerships between universities, governments, international organizations and the private sector. All nations therefore need to be producers of research as well as consumers of it. All nations will benefit from taking a systematic approach to the monitoring and evaluation of research investments, practices, outputs and applications.

Linas otassium, the most abundant cation in the human body, regu- lates intracellular enzyme function and neuromuscular tissue Pexcitability. Serum potassium is normally maintained within the narrow range of 3. The intracellular-extracellular potassium ratio (Ki/Ke) largely determ ines neurom uscular tissue excitability. Because only a small portion of potassium is extracel- lular, neuromuscular tissue excitability is markedly affected by small changes in extracellular potassium. Thus, the body has developed elaborate regulatory mechanisms to maintain potassium homeostasis. Because dietary potassium intake is sporadic and it cannot be rapidly excreted renally, short-term potassium homeostasis occurs via trans- cellular potassium shifts. Ultimately, long-term maintenance of potassium balance depends on renal excretion of ingested potassium. The illustrations in this chapter review normal transcellular potassium homeostasis as well as mechanisms of renal potassium excretion. W ith an understanding of normal potassium balance, disorders of potassium metabolism can be grouped into those that are due to altered intake, altered excretion, and abnormal transcellular distribu- tion. The diagnostic algorithms that follow allow the reader to limit the potential causes of hyperkalemia and hypokalemia and to reach a diagnosis as efficiently as possible. Finally, clinical manifestations of disorders of potassium metabolism are reviewed, and treatment algo- rithms for hypokalemia and hyperkalemia are offered. Recently, the m olecular defects responsible for a variety of diseases associated with disordered potassium m etabolism have been discov- C H A P T ER ered [3–8].

Schematic representation of the cellular mechanisms by which insulin and -adrenergic stimulation promote potassium uptake by extrarenal tissues. Insulin binding to its receptor results in hyperpo- larization of cell membranes (1), which facilitates potassium uptake. After binding to its receptor, insulin also activates Na+-K+-ATPase pumps, resulting in cellular uptake of potassium (2). The second messenger that mediates this effect has not yet been identified. Catecholamines stimulate cellular potassium uptake via the 2 adren- ergic receptor ( 2R). The generation of cyclic adenosine monophos- phate (3 , 5 cAM P) activates Na+-K+-ATPase pumps (3), causing an influx of potassium in exchange for sodium. By inhibiting the degradation of cyclic AM P, theophylline potentiates catecholamine- stimulated potassium uptake, resulting in hypokalemia (4).
