Less attention to monitoring superfluous variables and derived parameters, but a greater emphasis on attention to basics including maintaining or restoring the adequacy of organ perfusion, although with the relatively insensitive tools that we currently have available.
In the context of this Inquiry, what this episode illuminates is the adequacy (or otherwise) of the mechanism for maintaining the standards to which the press loudly asserts it adheres.
Using a vitamin D index in addition to the UV index for recommending sun exposure to achieve and/or maintain vitamin D adequacy, within the range of exposure that avoids adverse UVR effects, might be useful because the UV index is weighted by UVB and UVA wavelengths that produce erythema (sunburn), which is different from the UVB-only action spectrum for vitamin D photoproduction.
However, the optimal strategies to achieve and maintain vitamin D adequacy (sun exposure, vitamin D supplementation or both), and whether sun exposure itself has benefits over and above initiating synthesis of vitamin D, remain unclear.
Using this intervention study design, the SEDS Study will test whether advice to change the pattern of sun exposure can effectively achieve and maintain vitamin D adequacy (serum 25(OH D levels of 50 nmol/L or higher) over 12 months.
Nonetheless, only those insurers that maintain a capital adequacy ratio of 10% or above are entitled to take advantage of the new legislation, and even then they have to seek the insurance authority's approval before making any investment in bank deposits, commercial bills, bonds, money market funds and stocks.
Dairy products have a role in energy-restricted diets in helping maintaining nutritional adequacy but have no specific weight reducing properties [ 79].
The importance of genes in maintaining vitamin D adequacy is likely to be most significant in regions where UVR exposure is limited or is seasonally limited.
However, the relative contribution of genetic factors to maintaining 25(OH D adequacy is unclear, and published studies elucidating genes involved are scarce.
Firstly the study aims to assess and quantify the effect of advice to change the pattern of sun exposure in achieving and maintaining vitamin D adequacy, compared to different doses of vitamin D supplementation.
