IntechOpen and Knowledge Unlatched formed a partnership to support researchers working in engineering sciences by enabling an easier approach to publishing Open Access content. Using the Knowledge Unlatched crowdfunding model to raise the publishing costs through libraries around the world, Open Access Publishing Fee (OAPF) was not required from the authors.
\n\nInitially, the partnership supported engineering research, but it soon grew to include physical and life sciences, attracting more researchers to the advantages of Open Access publishing.

Vitamin K is an important fat-soluble vitamin. The discovery of vitamin K was in Germany in 1929 by Henrik Dam in his research on sterol metabolism, and he suggested the name vitamin K on the basis of its role in coagulation (koagulation in German spelling).
\nThe exact function of vitamin K in the human body was discovered in the 1970s with the discovery of γ-carboxyglutamic acid (Gla), an amino acid found in all vitamin K proteins [1].
\nGamma glutamyl carboxylase is an enzyme that located in the endoplasmic reticulum and mediates the posttranslational conversion of glutamyl to γ-carboxyglutamyl residues in vitamin K-dependent proteins; this enzyme needs vitamin K as a cofactor for this conversion; thus the important role of vitamin K appears in tissues that contain vitamin K-dependent protein to make them a functional protein [2].
\nDuring the last two decades, the researches have focused on the role of vitamin K in osteoporosis [3], cardiovascular disease [4], diabetes [5], and cancer [6] besides its role on coagulation [7].
\nIn the liver there are several vitamin K-dependent proteins which all play a role in hemostasis. In addition to the hepatic tissue, bone tissue contains vitamin K-dependent proteins such as osteocalcin (bone Gla protein) and matrix Gla protein (MGP). Mineral binding capacity of osteocalcin needs vitamin K for adding mineral to the bone matrix in normal bone growth and development [8].
\nStudies have reported that vitamin K plays a role in bone metabolism in other mechanisms. There is an evidence that vitamin K positively affects calcium balance and increase of calcium retention [9]. Vitamins K and D work synergistically on bone metabolism, the form of osteocalcin that osteoblasts produce is undercarboxylated osteocalcin, and this process is upregulated by vitamin D, while carboxylation of osteocalcin is mediated by vitamin K [10].
\nVitamin K is shown to decrease bone resorption by osteoclasts and inhibits production of bone-resorbing agents such as interleukin-6 [11] and prostaglandin E2 [12].
\nOsteoporosis is a metabolic bone disease of reduced bone density, fragile bone, and elevated susceptibility to fracture. Genetic factors, age, sex, race, general health, exercise, cigarette smoking, alcohol abuse, hormone replacement therapy, and nutrition are some of the factors that influence an individual’s risk of osteoporosis [13].
\nThe aim of the present paper is to summarize the present knowledge on vitamin K and bone metabolism, emphasize the role of vitamin K in bone health, and evaluate vitamin K as a diagnostic and therapeutic marker in osteoporosis.
\nVitamin K refers to a family of compounds with a common chemical structure of 2-methyl-1,4-naphthoquinone (Figure 1) [14].
\nStructure of the main forms of vitamin K.
These compounds include:
Vitamin K1 (phylloquinone)
Vitamin K2 (menaquinones)
Vitamin K3 (menadione) [7]
Vitamin K1 (phylloquinone) comes from vegetables, especially green leafy vegetables such as spinach, vegetable oils, broccoli, and some fruits [1].
\nVitamin K2 (menaquinone) forms a subfamily in which it has an unsaturated isoprenyl side chain (may range from 1 to 13 isoprene residues). The various menaquinones are generally denoted as MK-n, where n symbolizes the number of isoprene residues in the side chain and is designated as MK-4 through MK-13, established upon the length of their side chain. The most well-studied menaquinones are MK-4, MK-7, MK-8, MK-9, and MK-10 that all occur in the human diet.
\nMenaquinones (except MK-4) are of microbial origin, and relatively high concentrations are only found in a few food items. Natto (a traditional Japanese food made from fermented soybeans) has high amounts of menaquinones (almost exclusively MK-7). Other fermented foods, such as cheese, also contain menaquinones. However, the forms and amounts of vitamin K in these foods likely vary relying on the strains of bacteria utilized to make the foods.
\nBacteria in the human gut produce most of the menaquinones, especially the long-chain menaquinones; the amount of vitamin K that the body acquires in this manner is unclear.
\nMenadione is a synthetic form of vitamin K. It has increased toxic risk, so it is not a commonly supplemented form of vitamin K [1, 15].
\nIn the intestine vitamin K is incorporated into mixed micelles, and it is absorbed by enterocytes. From there, vitamin K is combined into chylomicrons, released into the lymphatic capillaries, transported to the liver, and then packed again into very-low-density lipoproteins. In the circulation, vitamin K is carried mainly in lipoproteins [16].
\nThe AI for vitamin K1 is 120 mcg/day for men and 90 mcg/day for women as it was determined by the Institute of Medicine in the United States in 2001 [17].
\nThese current AI values are established upon the hepatic vitamin K demanded for activation of coagulation factor and absence of abnormal bleeding. There was not any DRI for vitamin K2 or an upper limit intake level for vitamin K1 at that time. Clinical trials have used vitamin K supplements at doses much higher than the DRI levels (10 mg for vitamin K1 and 45 mg for vitamin K2) and found no evidence of toxic effects. However, trials which have used supplements of 45 mg/day of MK-4 demonstrate incidences of skin appendage lesions [18, 19].
\nVitamin K is being absorbed via chylomicrons; in addition it is distributed via lipoproteins. The menaquinones with longer side chain are partitioned into LDL, whereas others including vitamin K1 are in the triglyceride rich fragment [20]. Vitamin K does appear to bioaccumulate in various tissues following oral ingestion, and it appears to have a relatively short time in the body prior to being excreted in comparison with the fat-soluble vitamins [16].
\nThe major form of vitamin K in serum is vitamin K1, and it has a relative rapid half-life relative to MK-4, whereas MK-7 and other long-chain menaquinones have a very extended half-life and greater bioactivity [21].
\nThe normal range of circulating concentrations of vitamin K1 is 05–2.5 nM/L (0.22–1.22 ng/ml) without taking any supplements [22]. However the range of vitamin K1 in patients and healthy adults was 0,22–8.88 nM/L (0.09–3.96 ng/ml) as reported in several clinical studies [23].
\nOsteoblasts appear to take vitamin K which is transported via lipoproteins, and this uptake is facilitated by the LDL receptor which is expressed on these bone cells (LRP1 and, to a fewer degree, VLDLR) with the competence of the triglyceride fraction in giving its phylloquinone being greater than HDL but less than LDL, and the uptake is relying on ApoE. Hence it is thought that genetic variations in ApoE can affect vitamin K status. This region contains several Gla proteins such as matrix Gla protein and osteocalcin which need vitamin K to be effective [24].
\nDelivery of vitamin K to the bone tends to be less than in the liver, as in instances where vitamin K-dependent proteins (Gla) are totally γ-carboxylated in the liver, while they are not in the bone [20].
\nVitamin K plays a biological role as a cofactor of gamma glutamyl carboxylase, which mediates γ- carboxylation of glutamic acid residues (Glu) to γ-carboxyglutamic acid (Gla) on vitamin K-dependent protein. The Ƴ-carboxylation of the vitamin K-dependent proteins Gla proteins is essential for their function.
\nGla proteins or vitamin K-dependent proteins are a group of proteins that have calcium-binding characteristics and are existing in the extracellular matrix or in body fluids.
\nThese proteins are included in blood clotting, bone mineralization, cartilage, and other soft tissues; and they have an important role in supporting the health of bones, joints, and blood vessels [3]. Some studies have suggested that vitamin K has anticancer [6], anti-inflammatory, and antioxidant characteristics [25].
\nThere are seven different vitamin K-dependent proteins which all regulate coagulation; prothrombin (Factor II) is the most well-known target protein which was the first protein to be discovered to be γ-carboxylated by vitamin K. Afterwards factors VII, IX, and X as well as proteins C, S, and Z were discovered [8].
\nThere are not enough studies to determine a limit or threshold for concentration of vitamin K in serum that indicate deficiency or insufficiency [24].
\nVitamin K deficiency is rare among adults, and it is determined clinically by bleeding because of low activation of coagulation proteins and is often estimated by measurement of undercarboxylated prothrombin concentration in serum released from the liver. Its concentration increases with the degree of severity of vitamin K deficiency [26].
\nVitamin K deficiency is usually limited to people with liver and pancreas disease, cystic fibrosis, digestive disorders, disorders of fat malabsorption, chronic malnutrition, and alcohol dependency or those taking drugs that interfere with vitamin K metabolism such as vitamin K antagonist anticoagulants, bile acid sequestrants, certain types of antibiotics, and anticonvulsants [27].
\nThe more common condition is subclinical vitamin K deficiency that results in increased levels of undercarboxylated or even uncarboxylated Gla proteins in serum. This occurs when serum vitamin K concentration is ≤0.5 nM/L [28] or serum undercarboxylated osteocalcin is ≥4.0 ng/mL [26].
\nGla proteins that are not fully carboxylated are not activated and do not execute their role in the bone, cartilage, and soft tissue mineralization. Low vitamin K intake and low serum vitamin K concentrations are associated with increased risk of osteoporosis, cancer, and aortic calcification as observed by several studies [27, 28, 29].
\nSeveral vitamin K-dependent proteins have been verified. Some of them exist in the skeleton and cartilage such as osteocalcin, matrix Gla protein, Gla-rich protein, protein S, and gas 6 [30].
\nOsteocalcin is the first Gla protein discovered that originated from extrahepatic tissues. It is mainly produced by osteoblasts and has been suggested to affect bone metabolism by regulating osteoblast activity and bone mineralization [31].
\nOsteocalcin has three glutamic acid (Gla) residues which undergo gamma carboxylation by a process dependent on vitamin K; the Ƴ-carboxylation of osteocalcin is necessary for its function. Ƴ-carboxylated osteocalcin shows a high affinity to hydroxyapatite and bone matrix, contributing to bone formation. It has been shown that decarboxylated osteocalcin cannot bind calcium, thus emphasizing the importance role of vitamin K in the activation protein [32].
\nThe percentage of overall osteocalcin that remained uncarboxylated (% ucOC) is a biomarker of vitamin K status (more carboxylation indicates a better status, less carboxylation indicates a worse status), and osteocalcin continually gets carboxylated up until a daily intake of around 1000mcg phylloquinone. Dietary recommendations (120 μg/day for men, 90 μg/day for women) are based on saturation of the coagulation system. Requirements to maintain bone Gla protein function and bone formation might be higher [33, 34].
\nSome studies have demonstrated that elevated concentration of undercarboxylated osteocalcin in serum is a predictor of fractures [35, 36].
\nMGP is included in the organic matrix and mobilization of calcium in the skeleton. It is mainly synthesized in the bone, cartilage, dentine, and soft tissues, including blood vessels, and is also found in the brain, heart, kidney, liver, lung, and spleen [37, 38].
\nStudies also reported that vitamin K prevents bone resorption through a mechanism totally different from that of Ƴ-carboxylation. Vitamin K is shown to improve bone mineralization and decrease bone resorption by osteoclasts [39]. Other vitamin K roles have also been reported such as it can promote fracture reparation by stimulating bone formation and decrease calcium excretion by urine [3]. These results confirm the significant role of vitamin K in bone metabolism.
\nVitamin K also functions as a ligand of steroid and xenobiotic receptor (SXR) and its murine homolog, pregnane X receptor (PXR), which after heterodimerization with the vitamin A receptor (RXR) induces the target genes including tsukushi (
\n
It has been reported that osteoporosis is linked with oxidative stress. Moreover, supplementation of vitamin K as an antioxidant vitamin could effectively reduce levels of oxidative stress, with possibly advantageous influence on bone, as displayed in several experimental models [27].
\nIt is possible that higher levels of vitamin K suppress IL-6 secretion from inflammatory stressors, although the mechanisms underlying this are not currently known [11]. In addition, vitamin K also represses osteoclast activity, therefore averting the breakdown of bone [40].
\nOsteoporosis is a metabolic bone disease of reduced bone density, fragile bone, and elevated susceptibility to fracture [41]. Risk factors for osteoporosis contain genetic, nutrition, and hormone [3].
\nIt is a common disease affecting 1 in 3 women and 1 in 12 men, resulting in substantial morbidity, excess mortality, and health and social services spending. It is therefore important to improve strategies for prevention and treatment osteoporosis in both men and women [42].
\nSome studies showed that the administration of vitamin K led to an increase of bone mineral density (BMD) in osteoporotic patients (Vermeer et al. [43]). In addition, administration of vitamin K was found to prevent bone loss and reduce the incidence of fractures (Shiraki et al. [44]).
\nA survey investigating vitamin K intake data from the fifth Korea National Health and Nutrition Examination Survey reported that low dietary vitamin K intake was related to low bone mineral density in subjects who were included (2785 men, 4307 women aged over 19 years). In addition, there was a reduction in risk for osteoporosis as vitamin K intake increased in women, but this effect was not continued after adjusting factors. This survey recommended increasing the dietary VK intakes for preserving BMD [45].
\nA study by Fujita et al. [46] observed that high intake of natto, fermented soybean high in phylloquinone, and MK-7 was associated with higher BMD, which was also demonstrated in a study by Ikeda et al. [47].
\nA cross-sectional study (3199 middle-aged Scottish females included) reported that females in the highest quartile of dietary intake of vitamin K1 (162 mcg/day) have a significantly higher lumbar spine (L2–L4) BMD and left femoral neck BMD against the lowest quartile (59 mcg/day) [48]. In vitro experiments by Hara et al. showed that vitamin K inhibits bone resorption induced by IL-la, PGE, PTH, and vitamin D3 in a dose-dependent manner [12].
\nSeveral studies have shown the relation between vitamin K and bone mineral density; a study by Kanai et al. reported that postmenopausal women with decreased bone mineral density (mean BMD, 0.73 g/cm2) had significantly lower levels of vitamin K1 and MK-7 than women with normal bone density (mean BMD, 0.99 g/cm2) [49].
\nIn our study we found that serum vitamin K1 level was significantly lower in the postmenopausal osteoporotic women group than in the normal control group, the mean serum vitamin k1 level was significantly lower in the postmenopausal osteoporotic women group than in the normal control group (mean = 0.794 vs. 3.61 ng/ml, P < 0.0001), and serum vitamin k1 concentration was positively correlated with lumbar spine BMD among postmenopausal osteoporotic women (R = 0.533, p = 0.009) and in postmenopausal healthy control (R = 0.563, p = 0.02). Diagnostic sensitivity and specificity of vitamin k1 for osteoporosis were 90 and 98%, respectively (cutoff value: 0.853 ng/ml). The area under the ROC curve (AUC) value for vitamin k1 was 0.984; the odd ratio result was 18.66 [50]. The same result was reported also by Heiss et al. [51].
\nThese findings may suggest a role of vitamin K in bone metabolism. And therefore it has been thought that it might be effective for treating osteoporosis. Furthermore, Booth et al. [52] found that low plasma vitamin K1 concentrations were associated with low spine BMD among postmenopausal women not using estrogen replacement. These findings suggest a protective role of vitamin K in the skeleton in women. In addition, poor vitamin K nutritional status (low plasma phylloquinone concentrations and high serum %ucOC) was correlated with low BMD at the hip among men.
\nHigh incidence of vertebral fractures has reported to be contrarily correlated with BMD of lumbar spine and vitamin k1 concentration in the study on 379 Japanese women of 30–88 years to 4 years [53].
\nVitamin K was found to increase bone mineral density in an in vivo osteoporosis model. A study by Hodges et al. deduced that osteoporotic patients had decreased levels of vitamin K and increased levels of non Ƴ-carboxylated osteocalcin [54].
\nThe relations between vitamin K intake and bone mineral density are not coherent in observational studies [27].
\nFang et al. showed that vitamin K supplements did not have influence on BMD at the femoral neck, but there was an increase in mean lumbar spine BMD by 1.3% (95% CI: 0.5–2.1) after supplementation for 6–36 months.
\nIn this meta-analysis, seven studies utilized vitamin K1 with portions ranging from 0.2 to 10 mg/day. Ten studies utilized vitamin K2 (eight used MK-4 with portions of 15–45 mg/day, and two studies utilized MK-7 with portions of 0.2–3.6 mg/day), and after studies with high risk of bias have been excluded, the writer deduced that supplementation with vitamin K did not have significant effect on lumbar spine BMD in their subgroup analysis; they found that supplementation with vitamin K2 increased mean lumber spine BMD by 1.8% (95% CI, 0.9–2.8). No such influence was realized for studies with vitamin K1 supplementation [19].
\nIt has been reported that osteoporosis is related to oxidative stress. Moreover, supplementation of vitamin K, as an antioxidant vitamin, could effectively decrease levels of oxidative stress, with possibly beneficial effect on the bone, as displayed in several experimental models [55].
\nVitamin K is necessary for bone health. In fact, low vitamin K intake, low vitamin K circulating levels, and high undercarboxylated osteocalcin levels are all related with excessive hip fractures risk in observational studies [15].
\nMore studies are required regarding the influences of vitamin K on diagnosis and management of osteoporosis and similarly on BMD.
\nStudies suggest that vitamin K has a role in bone metabolism and it may contribute in maintaining BMD and diagnosing osteoporosis. Studies have demonstrated that in the healthy population, all clotting factors are synthesized in their active form, whereas the synthesis of other Gla proteins is sub-optimal in non-supplemented subjects. Prolonged subclinical vitamin K deficiency is a risk factor for osteoporosis. Present recommendations for dietary intake are based on the daily dose required to prevent bleeding. Scientific data suggests that new, higher recommendations for vitamin K intake should be formulated.

The advantage of non-pharmacological treatments is that they are relatively inexpensive and safe.",book:{id:"7289",slug:"pain-management-in-special-circumstances",title:"Pain Management in Special Circumstances",fullTitle:"Pain Management in Special Circumstances"},signatures:"Ahmed El Geziry, Yasser Toble, Fathi Al Kadhi, Muhammad Pervaiz\nand Mohammad Al Nobani",authors:null},{id:"73348",title:"The Role of Cupping Therapy in Pain Management: A Literature Review",slug:"the-role-of-cupping-therapy-in-pain-management-a-literature-review",totalDownloads:978,totalCrossrefCites:0,totalDimensionsCites:0,abstract:"Cupping therapy is an ancient method which has been used for centuries for various painful conditions. It is performed by applying cups to selected skin points most commonly in the back aiming to create areas of sub-atmospheric pressure. It has been classified as either dry or wet type of therapy. Its mechanism of action is not well understood but several proposed mechanisms are described in the literature. It is relatively safe with a few reported side effects which include scar formation and skin infection. In this paper, a review of the literature will be presented to determine its potential benefits in pain management particularly in musculo-skeletal conditions such as low back and neck pain.",book:{id:"9483",slug:"pain-management-practices-novel-therapies-and-bioactives",title:"Pain Management",fullTitle:"Pain Management - Practices, Novel Therapies and Bioactives"},signatures:"Asma Al-Shidhani and Abdulaziz Al-Mahrezi",authors:[{id:"248467",title:"Dr.",name:"Abdulaziz",middleName:null,surname:"Al-Mahrezi",slug:"abdulaziz-al-mahrezi",fullName:"Abdulaziz Al-Mahrezi"},{id:"322652",title:"Dr.",name:"Asma",middleName:null,surname:"Al-Shidhani",slug:"asma-al-shidhani",fullName:"Asma Al-Shidhani"}]},{id:"63560",title:"Pain Management for the Sickle Cell Patient",slug:"pain-management-for-the-sickle-cell-patient",totalDownloads:1138,totalCrossrefCites:0,totalDimensionsCites:0,abstract:"Sickle cell disease (SCD) is a condition very common in the United States of America and its most common presenting symptom is pain related to vaso-occlusive events (VOE). The cost associated with healthcare for the sickle cell population exceeds 1 billion $USD yearly, and the majority of this cost is associated with admission related to vaso-occlusive events. With the increase longevity of patients with SCD, due to new therapies and vaccination against common infection related to SCD, the prevalence of older individuals experiencing VOE will likely increase. The psychological impact inflicted on patients with SCD can further complicate adequate care of patients experiencing acute or chronic pain and the latter must be taken into consideration when planning an optimal treatment regimen. This chapter reviews the short- and long-term management options of pain related to VOE, their limitations as well proposed regimen that could pave the way for the future of pain management of SCD.",book:{id:"7289",slug:"pain-management-in-special-circumstances",title:"Pain Management in Special Circumstances",fullTitle:"Pain Management in Special Circumstances"},signatures:"Thomas Zouki, Armen Haroutunian and Tennison Malcolm",authors:null},{id:"62009",title:"Acute Pain Management in Intensive Care Patients: Facts and Figures",slug:"acute-pain-management-in-intensive-care-patients-facts-and-figures",totalDownloads:1720,totalCrossrefCites:4,totalDimensionsCites:3,abstract:"Pain is an unpleasant experience for all patients including intensive care patients; if it is not treated properly, it has deleterious effects on patients’ acute and chronic well-beings. In ICU patients, it causes sympathetic stimulation leading to adverse hemodynamic effects and after discharge, these patients are at the higher risk for developing chronic pain and post-traumatic stress disorders. Apart from racial and regional factors, sleep deprivation, anxiety, and delirium increase the pain perceptions. Pain assessment is a prerequisite for adequate pain management. The ICU patients are sedated and ventilated, and assessment scales differ depending on whether the patient is able to communicate. There are different pain assessment scales for both groups of patients. The preferred mode of delivery of analgesic medication is intravenous route as intramuscular and subcutaneous route are not reliable for drug delivery in these patients. Patient and nurse controlled analgesia gives better sense of pain control. In the treatment of pain, opioids are the commonly used medications, but paracetamol, dexmedetomidine, and gabapentin are increasingly used. Newer trends are multimodal analgesia, where the combinations of analgesic medications with different mechanism of action are used. Another trend is increasing use of analgosedation; they not only control the pain but also relieve anxiety.",book:{id:"7289",slug:"pain-management-in-special-circumstances",title:"Pain Management in Special Circumstances",fullTitle:"Pain Management in Special Circumstances"},signatures:"Nissar Shaikh, Saher Tahseen, Qazi Zeesan Ul Haq, Gamal Al-Ameri,\nAdel Ganaw, Arshed Chanda, Muhammed Zubair Labathkhan and\nTariq Kazi",authors:[{id:"107703",title:"Dr.",name:"Nissar",middleName:null,surname:"Shaikh",slug:"nissar-shaikh",fullName:"Nissar Shaikh"}]},{id:"66349",title:"Food-Derived Opioids: Production and the Effects of Opioids on Human Health",slug:"food-derived-opioids-production-and-the-effects-of-opioids-on-human-health",totalDownloads:1370,totalCrossrefCites:3,totalDimensionsCites:3,abstract:"Traditional opioids have been used for the people who suffer from cancer, burns, surgery, HIV/AIDS, and other serious illness pains for years.
