Guidelines on the management of osteoporosis do not make recommendations that relate to people with CKD cheap 160 mg super p-force oral jelly visa erectile dysfunction and prostate cancer. It is then hydroxylated in the liver to form 25-hydroxyvitamin D (calcidiol) and then hydroxylated 160 13 Specific complications of CKD – renal bone disease in the kidney to 1 purchase super p-force oral jelly 160 mg on line erectile dysfunction causes cancer,25-dihydroxyvitamin D (calcitriol), which is the most active form. Vitamin D deficiency can therefore occur as a result of decreased intake or absorption, reduced sun exposure, increased hepatic catabolism, or decreased endogenous synthesis (via 25-hydroxylation in the liver and subsequent 1-hydroxylation in the kidney). Active vitamin D has a variety of actions on calcium, phosphate, and bone metabolism. By increasing intestinal calcium and phosphate reabsorption and increasing the effect of parathyroid hormone (PTH) on bone, in health vitamin D has the net effect of increasing the serum calcium and phosphate concentrations. Vitamin D deficiency or resistance interferes with these processes, sometimes causing hypocalcaemia and hypophosphataemia. Since hypocalcaemia stimulates the release of PTH, however, the development of hypocalcaemia is often masked. The secondary hyperparathyroidism, via its actions on bone and the kidney, partially corrects the hypocalcaemia but enhances urinary phosphate excretion, thereby contributing to the development of hypophosphataemia. In people with CKD the kidney component of this loop is increasingly compromised as CKD advances. As renal function declines, the hydroxylating activity of renal 1α-hydroxylase on 25-hydroxy- vitamin D3 also decreases, resulting in decreased production of active vitamin D (1,25-dihydroxy- vitamin D3) and decreased intestinal absorption of calcium. The decrease in calcium and active vitamin D3 alleviates the repression of parathyroid hormone (PTH) production, resulting in hyperproliferation of parathyroid cells. High PTH levels cause an increase in bone remodelling, leading to high bone-turnover (osteitis fibrosa), loss of bone density and structure. This excess bone remodelling liberates calcium and phosphorus from bone, resulting in hypercalcaemia and hyperphosphataemia and increasing the risk for vascular calcification. Vitamin D supplementation in people with CKD should therefore be driven by the underlying metabolic abnormality. This in turn will depend on the stage of CKD but is complicated by the fact that in the population with the highest prevalence of CKD, the older population, vitamin D deficiency is common. Cutaneous vitamin D production and vitamin D stores decline with age coupled with the fact that intake is often low in older subjects. Furthermore, even in those with adequate vitamin D intake, achlorhydria, which is common in older people, limits vitamin D absorption. Nutritional forms of vitamin D include ergocalciferol and cholecalciferol; active forms of vitamin D include alfacalcidol, calcitriol and paricalcitol. Elderly patients are likely to be vitamin D deficient from diet, lack of sunlight and poor absorption for which they will need nutritional vitamin D. However as CKD progresses (particularly in stages 4 and 5), renal function is impaired to such a degree that active vitamin D may also be required. Outcomes of interest included adverse events, fractures, changes in serum calcium, phosphorus, PTH, osteocalcin, alkaline phosphatase, GFR, and bone mineral density. All of these studies are limited by small sample sizes (N=25–220), and very few presented intention to treat analyses. There were no studies of acceptable methodological quality that compared different vitamin D metabolites head-to-head. Two of these RCTs titrated the dose of calcitriol from 0. One RCT compared 6 months of treatment with calcitrol (N=8, 1 µg/day) or calcidiol (N=9, 4000 IU/day) in people with chronic renal failure. Two RCTs investigated the effects of treatment with alfacalcidol (1-α-hydroxycholecalciferol) compared to placebo in people with mild to moderate CKD (creatinine clearance 10–60 ml/min). RCT (N=89 alfacalcidol and N=87 placebo, 24 months follow-up) titrated the dose of alfacalcidol from 0. Most of the participants had abnormal bone histology at baseline (NS difference between the trial arms). A pooled analysis of 3 RCTs with identical inclusion/exclusion criteria and different dosing regimens (3 times weekly or once daily) compared paricalcitol (N=107, 6 months follow-up, mean dose was 1. Although this study was not a systematic review, it was included as an RCT (albeit pooled) due to lack of studies of non-dialysis CKD populations. Serum calcium One RCT showed that serum calcium significantly increased with calcitrol (0.

Acceptability of the Patient Centred Assessment Method intervention for nurses For nurses cheap 160mg super p-force oral jelly with visa erectile dysfunction statistics by age, the PCAM was fairly easily integrated into a consultation discount super p-force oral jelly 160mg mastercard icd 9 code for erectile dysfunction due to medication, although some participants reflected that the process of integration took some time and support. The nurse participants perceived this to be beneficial for both the patient and the nurse, both in relation to the quality of the relationship and the quality of the care provided. Nurses found the resource pack very useful and had been active in signposting patients to various sources of support. This seemed to be accompanied by an approach that involved helping patients to access support for themselves and to address what their own priorities were, rather than focusing on fixing purely clinical issues. Long-term adoption of the PCAM appears likely for some of the nurse participants involved in this research, beyond the research project itself. Acceptability of the Patient Centred Assessment Method intervention for patients The patient participants who were interviewed did not notice any apparent difference to their annual review post PCAM implementation. However, patients did describe talking with their nurse about their lives and their broader concerns during reviews, and described welcoming these conversations with their nurse. PCAM implementation did not have a negative or obstructive impact on the consultation. Process evaluation There needs to be flexibility in how training and support is delivered. Brief training, followed by nurse reflection on the PCAM, alongside testing small areas of the PCAM and building up to its full use, can be interspersed with training/support sessions as nurses become more familiar and confident with the process or need to come back and ask questions. Training needs to include more on boundaries and how to deal with complex issues over a number of reviews. When this was emphasised in later training sessions, it helped the PNs to see that it was not designed to solve all problems. The resource pack is an integral part of the PCAM intervention for ensuring that nurses feel confident that they can do something about the issues raised during consultations. Practices need to identify a resource champion who can keep the resource list up to date. In some cases, the practice manager saw this as a role they could fulfil. Overall, there were few adaptations required to the PCAM intervention beyond flexibility in delivery of training. Dedicated researcher support is needed to support data collection in both phases, especially for the first couple of clinics or until researchers are confident that research processes are operating as required.

SCIENTIFIC SUMMARY More exploratory work is needed into acceptable methods for monitoring adherence/fidelity to the PCAM by nurses, and understanding nurse reluctance towards consultation recording. Conclusions The PCAM has been shown to be feasible and acceptable for use in primary care in the UK. In addition, it has been shown that the PCAM does indeed have the potential to change the ways in which nurses engage with patients with LTCs in the context of LTC reviews, resulting in more attention being paid to the mental well-being and social care needs of patients. The PCAM is more likely to be feasible when nurses see the asking of these questions as part of the role of nursing, view their role as facilitating links to information or resources that can address concerns (rather than feeling that they have to address the concerns themselves) and have the information about resources available to them, and when there is a whole-practice commitment to the approach. Any future study of implementing or testing of the PCAM in primary care would require these conditions to be met. Recommendations The PCAM intervention warrants further exploration as an effective mechanism for improving the quality of care for people with LTCs in primary care, particularly in the holistic review of patient needs by primary care nurses. A full-scale cluster randomised trial is not recommended within the current climate of primary care research participation in Scotland. This may also include the rest of UK general practice, and a brief survey by primary care research networks in England may determine whether or not this is also the case in England. Research should explore nurse reluctance towards having their consultations recorded in order to assess whether or not this is still a potential mechanism for assessing fidelity to the PCAM.
