Should We Worry About Nutrition Of Adults With Minor Burns? An Audit Of Their Intakes.

Small burn injuries are managed in an outpatient setting by surgeons and/or nurses. Nutrition in minor burn patients is rarely investigated. This observational study aimed to quantify their nutritional intakes, and o compare them to theoretical adequate values. Their average daily food intakes since injury were evaluated by a dietician using a ten-point visual assessment of consumed portions during the last meal (SEFI tool) and a food anamnesis. Macro- and micronutrient intakes were compared to national recommended dietary allowances (RDA) for healthy subjects: intakes <66% RDA were considered inadequate. Forty-two patients with a median age of 45 (34-56) years, BMI of 25.9 (23.5-28.9) kg/m2, and burn surface area (BSA) of 2 (1-3) % were included. Energy and protein RDA were reached in 28.6 and 71.4% of the patients, respectively. Intakes of n-3 fatty acids were inadequate in 80.9% of the patients. A SEFI <7 was associated with insufficient intakes regards both energy and proteins. Inadequate intakes of different micronutrients were frequently observed, but no risk factors could be detected. Vitamin A and C were the most impacted: 71.4% of the patients had inadequate intakes. Vitamin D intake was low: 225 (56-431) UI/d. In contrast, intakes of iron, selenium and zinc were adequate in at least 61.9% of the patients. In conclusion, this audit highlighted that a majority of macronutrient and micronutrient intakes did not reach the levels recommended by the RDA. Such data should help in designing further studies aimed at assessing the impact of optimized nutrition on outcomes.

Certains patients, souffrant de brûlures mineures, sont suivis en externe par des chirurgiens et/ou des infirmières. La nutrition de tels patients est rarement étudiée. Cette étude observationnelle a pour but de quantifier leurs apports nutritionnels et de les comparer aux apports théoriques nécessaires. Leurs apports moyens depuis la brûlure ont été évalués par une diététicienne en utilisant une échelle visuelle (0 à 10) d'évaluation des portions consommées lors du dernier repas (échelle SEFI) et un historique de leurs repas. Les apports macro- et micronutritionnels réels ont été comparés aux apports recommandés aux sujets sains, un apport <66 % étant considéré comme insuffisant. Quarante deux patients d'âge médian de 45 ans (34- 56), à l'IMC de 25,9 (23,5- 28,9) kg/m² et brûlés sur 2 % (1- 3) SCT ont été inclus. Les apports en énergie et protéines étaient suffisants dans 28,6 et 71,4 % des cas. Ceux en acides gras 3 étaient insuffisants dans 80,9 % des cas. Un SEFI < 7 était associé à des apports insuffisants aussi bien en calories qu'en protéines. Des apports insuffisants en micronutriments étaient fréquemment observés, sans facteur de risque particulier, les apports en vitamines A et C étant ceux ayant été le plus souvent considérés comme insuffisants (dans 71,4 % des cas). Les apports de vitamine D (225- 56/431) UI/j étaient faibles eux aussi. À l'opposé, les apports en Fe, Se et Zn étaient considérés comme satisfaisants chez au moins 61,9 % des patients. En conclusion, cette étude montre que les patients, dans leurs majorité, n'ingèrent pas les quantités de macro- et micronutriments recommandés. Elle peut servir de point de départ à des études évaluant l'impact d'une optimisation nutritionnelle dans cette situation.

Assessment of Cardiovascular Safety of Anti-Osteoporosis Drugs.

The incidence of osteoporosis and cardiovascular disease increases with age, and there are potentially shared mechanistic associations between the two conditions. It is therefore highly relevant to understand the cardiovascular implications of osteoporosis medications. These are presented in this narrative review. Calcium supplementation could theoretically cause atheroma formation via calcium deposition, and in one study was found to be associated with myocardial infarction, but this has not been replicated. Vitamin D supplementation has been extensively investigated for cardiac benefit, but no consistent effect has been found. Despite findings in the early 21st century that menopausal hormone therapy was associated with coronary artery disease and venous thromboembolism (VTE), this therapy is now thought to be potentially safe (from a cardiac perspective) if started within the first 10 years of the menopause. Selective estrogen receptor modulators (SERMs) are associated with increased risk of VTE and may be related to fatal strokes (a subset of total strokes). Bisphosphonates could theoretically provide protection against atheroma. However, data from randomised trials and observational studies have neither robustly supported this nor consistently demonstrated the potential association with atrial fibrillation. Denosumab does not appear to be associated with cardiovascular disease and, although parathyroid hormone analogues are associated with palpitations and dizziness, no association with a defined cardiovascular pathology has been demonstrated. Finally, romosozumab has been shown to have a possible cardiovascular signal, and therefore post-market surveillance of this therapy will be vital.

Alternative and complementary therapies in osteoarthritis and cartilage repair.

Osteoarthritis (OA) is the most common joint condition and, with a burgeoning ageing population, is due to increase in prevalence. Beyond conventional medical and surgical interventions, there are an increasing number of 'alternative' therapies. These alternative therapies may have a limited evidence base and, for this reason, are often only afforded brief reference (or completely excluded) from current OA guidelines. Thus, the aim of this review was to synthesize the current evidence regarding autologous chondrocyte implantation (ACI), mesenchymal stem cell (MSC) therapy, platelet-rich plasma (PRP), vitamin D and other alternative therapies. The majority of studies were in knee OA or chondral defects. Matrix-assisted ACI has demonstrated exceedingly limited, symptomatic improvements in the treatment of cartilage defects of the knee and is not supported for the treatment of knee OA. There is some evidence to suggest symptomatic improvement with MSC injection in knee OA, with the suggestion of minimal structural improvement demonstrated on MRI and there are positive signals that PRP may also lead to symptomatic improvement, though variation in preparation makes inter-study comparison difficult. There is variability in findings with vitamin D supplementation in OA, and the only recommendation which can be made, at this time, is for replacement when vitamin D is deplete. Other alternative therapies reviewed have some evidence (though from small, poor-quality studies) to support improvement in symptoms and again there is often a wide variation in dosage and regimens. For all these therapeutic modalities, although controlled studies have been undertaken to evaluate effectiveness in OA, these have often been of small size, limited statistical power, uncertain blindness and using various methodologies. These deficiencies must leave the question as to whether they have been validated as effective therapies in OA (or chondral defects). The conclusions of this review are that all alternative interventions definitely require clinical trials with robust methodology, to assess their efficacy and safety in the treatment of OA beyond contextual and placebo effects.

Impact of frailty status on the cost of drugs and dietary supplements prescribed to nursing home residents: the SENIOR cohort.

BACKGROUND: The financial impact associated with drug consumption has been poorly investigated among frail subjects and, specifically, in nursing home settings. AIMS: To determine the association of the average monthly cost of the drugs and dietary supplements consumed by nursing home residents with their frailty status. METHODS: This is an analysis of the first follow-up year of the SENIOR cohort. All participants were classified into "frail" or "non-frail" categories according to Fried's criteria at baseline. Monthly bills from the pharmacy were analysed to determine the association between the average monthly cost of the drugs and dietary supplements consumed and frailty status. RESULTS: A sample of 87 residents (83.8 ± 9.33 years and 75.9% women) from the SENIOR cohort was included. The prevalence of frailty was 28%. The median number of medications consumed each day was 9 (6-12) (no difference between frail and non-frail subjects; p = 0.15). The overall median monthly cost was € 109.6, of which 49% was covered by Belgian social security and the remaining balance was paid by the patient. When comparing the drug expenses of the frail subjects and the non-frail subjects, the overall average monthly cost did not differ between the 2 groups (p = 0.057). Nevertheless, the expenditure remaining to be paid by the residents, after the Belgian social security intervention, was significantly higher among the frail residents (€ 65.7) than among the non-frail residents (€ 47.6; p = 0.017). CONCLUSIONS: Frailty status has an impact on the expenditures related to the consumption of drugs.

[Vitamin D deficiency during pregnancy : what's the local situation ?] / Prévalence de l'hypovitaminose D chez la femme enceinte : quelle est la situation en région liégeoise ?

Vitamin D deficiency is a worldwide health problem, also during pregnancy. Inadequate maternal vitamin D status in pregnancy is associated with poor fetal growth, impaired bone development and rickets in infants after birth. Furthermore, higher rates of preeclampsia and gestational diabetes are associated with low maternal vitamin D status during pregnancy. Toxicity of vitamin D is rare. Most countries recommend vitamin D supplementation during pregnancy but guidelines are controversial and inadequate compared to real mother's and child's needs. Wath's the best strategy to follow and supplement mother during pregnancy? In a study carried out at the maternity clinic Notre-Dame des Bruyères (CHU Liège), we studied for a year the vitamin D concentrations of young women at start of pregnancy and of others after delivery to evaluate the local situation and management of vitamin D status during pregnancy. We did not collect the cord blood samples in this study. However, this is a project we would like to achieve soon. This would allow us to compare the vitamin D results of the mother at the time of delivery, to those of the cord blood of their respective child.

Les déficiences en vitamine D sont très répandues dans la population générale liégeoise, mais aussi chez la femme enceinte. Les ressources en vitamine D du nouveau-né sont complètement dépendantes de celles de sa mère. Les déficiences maternelles sont associées à un risque accru de rachitisme, de faible minéralisation osseuse, de naissance avant terme et de faible poids à la naissance chez l'enfant et de pré-éclampsie, de diabète gestationnel et d'accouchement par césarienne chez la mère. Les recommandations de supplémentation en vitamine D durant la grossesse sont très variées et semblent insuffisantes pour couvrir les besoins réels de la mère et de l'enfant. Quelle stratégie adopter pour un suivi correct et une supplémentation suffisante pendant la grossesse ? Dans une étude réalisée à la maternité de la clinique Notre-Dame des Bruyères (CHU Liège), nous avons étudié, pendant une année, les concentrations en vitamine D chez des jeunes femmes en début de grossesse et chez d'autres en fin de grossesse afin d'évaluer la situation locale et la prise en charge du statut en vitamine D pendant la grossesse. Nous n'avons pas récolté les échantillons de sang de cordon dans cette étude. Il s'agit cependant d'un projet que nous souhaiterions réaliser prochainement, ce qui nous permettrait de comparer les résultats en Vitamine D de la mère au moment de l'accouchement, à ceux du sang du cordon de leur enfant respectif.

Effects of Protein, Essential Amino Acids, B-Hydroxy B-Methylbutyrate, Creatine, Dehydroepiandrosterone and Fatty Acid Supplementation on Muscle Mass, Muscle Strength and Physical Performance in Older People Aged 60 Years and Over. A Systematic Review on the Literature.

OBJECTIVES: The objective of this study was to perform a systematic review to investigate the effects protein, essential amino acids (EAA), ß-hydroxy ß-methylbutyrate (HMB), creatine, dehydroepiandrosterone (DHEA) and fatty acid supplementation on muscle mass, muscle strength and physical performance of elderly subjects. METHODS: Using the electronic databases MEDLINE and EMBASE we identified RCTs published until February 2016 which assessed the effects of these nutrient supplementation on muscle strength, muscle mass or physical performance. Study selection and data extraction were performed by two independent reviewers. RESULTS: Search strategy allowed us to identify 23 RCTs. Among them, four used proteins as nutritional supplement, seven EAAs, six creatine, four DHEA and finally, two HMB. From our systematic review, it seems that the effects of these supplementations on muscle health are rather limited. Only consistent effects of EAA supplementation on physical performance (3 out of the 4 RCTs using EAA supplementation found significant effect of this supplementation on physical performance) and HMB supplementation on muscle mass (all the 2 identified RCTs using HMB supplementation found significant effect of this supplementation on muscle mass) have been found across studies. No consistent effects were found for the other types of dietary supplementation. Because of the important limitations in study design, inconsistency and lack of directness, the overall quality of the evidence was judged to be low or very low using the GRADE system. CONCLUSION: This systematic review showed a limited effect of nutritional supplementation on muscle mass, muscle power and physical function. Inconsistent positive effects were observed for some specific supplementations but the results only concerned one aspect of the muscle. Well designed and appropriately powered RCTs are needed to provide evidence for appropriate clinical recommendations.

Does nutrition play a role in the prevention and management of sarcopenia?

There is a growing body of evidence that links nutrition to muscle mass, strength and function in older adults, suggesting that it has an important role to play both in the prevention and management of sarcopenia. This review summarises the discussions of a working group [ESCEO working group meeting 8th September 2016] that met to review current evidence and to consider its implications for preventive and treatment strategies. The review points to the importance of 'healthier' dietary patterns that are adequate in quality in older age, to ensure sufficient intakes of protein, vitamin D, antioxidant nutrients and long-chain polyunsaturated fatty acids. In particular, there is substantial evidence to support the roles of dietary protein and physical activity as key anabolic stimuli for muscle protein synthesis. However, much of the evidence is observational and from high-income countries. Further high-quality trials, particularly from more diverse populations, are needed to enable an understanding of dose and duration effects of individual nutrients on function, to elucidate mechanistic links, and to define optimal profiles and patterns of nutrient intake for older adults.

Nutrition and physical activity in the prevention and treatment of sarcopenia: systematic review.

This systematic review summarizes the effect of combined exercise and nutrition intervention on muscle mass and muscle function. A total of 37 RCTs were identified. Results indicate that physical exercise has a positive impact on muscle mass and muscle function in subjects aged 65 years and older. However, any interactive effect of dietary supplementation appears to be limited. INTRODUCTION: In 2013, Denison et al. conducted a systematic review including 17 randomized controlled trials (RCTs) to explore the effect of combined exercise and nutrition intervention to improve muscle mass, muscle strength, or physical performance in older people. They concluded that further studies were needed to provide evidence upon which public health and clinical recommendations could be based. The purpose of the present work was to update the prior systematic review and include studies published up to October 2015. METHODS: Using the electronic databases MEDLINE and EMBASE, we identified RCTs which assessed the combined effect of exercise training and nutritional supplementation on muscle strength, muscle mass, or physical performance in subjects aged 60 years and over. Study selection and data extraction were performed by two independent reviewers. RESULTS: The search strategy identified 21 additional RCTs giving a total of 37 RCTs. Studies were heterogeneous in terms of protocols for physical exercise and dietary supplementation (proteins, essential amino acids, creatine, ß-hydroxy-ß-methylbuthyrate, vitamin D, multi-nutrients, or other). In 79% of the studies (27/34 RCTs), muscle mass increased with exercise but an additional effect of nutrition was only found in 8 RCTs (23.5%). Muscle strength increased in 82.8% of the studies (29/35 RCTs) following exercise intervention, and dietary supplementation showed additional benefits in only a small number of studies (8/35 RCTS, 22.8%). Finally, the majority of studies showed an increase of physical performance following exercise intervention (26/28 RCTs, 92.8%) but interaction with nutrition supplementation was only found in 14.3% of these studies (4/28 RCTs). CONCLUSION: Physical exercise has a positive impact on muscle mass and muscle function in healthy subjects aged 60 years and older. The biggest effect of exercise intervention, of any type, has been seen on physical performance (gait speed, chair rising test, balance, SPPB test, etc.). We observed huge variations in regard to the dietary supplementation protocols. Based on the included studies, mainly performed on well-nourished subjects, the interactive effect of dietary supplementation on muscle function appears limited.

The internet as a source of information used by women after childbirth to meet their need for information: A web-based survey.

OBJECTIVE: the aims of this survey were: (a) to evaluate the need of information after childbirth and what questions do 'new' mothers ask themselves; (b) to assess why and how women use the Internet to meet their need of information; (c) to describe how the respondents evaluate the reliability of the information found; (d) to understand how the information found on the Internet affects women's decision-making; and (e) to appreciate how health professionals react to the information found by the women. DESIGN: this study used a large web-based survey that was widely broadcasted on various websites and social networks. SETTING AND PARTICIPANTS: belgian women who had a child under 2 years old and who agreed to participate were included in the study. FINDINGS: 349 questionnaires were valid for analyses. After childbirth, 90.5% of women admitted to using the Internet to seek information about themselves or about their baby, regardless of socioeconomic status or age. There were various reasons for seeking information on the Internet, but the most frequent reason the women expressed was to find information 'on their own' (88.1%). The most searched for topic was breastfeeding. The women believed that the information was quite useful (82.7%) but they assigned an average score of 5.3 out of 10 for the quality of the information they found on the Internet. Approximately 80% of the women felt that the Internet helped them control a decision that they made 'a little', 'often' or 'very often'. Professionals are not always willing to talk about information found on the Internet with mothers. Therefore, many women believed that health professionals should suggest reliable Internet websites for new mothers. CONCLUSIONS: the integration of the Internet and new technologies could be a useful tool during postpartum management.

The role of calcium supplementation in healthy musculoskeletal ageing : An expert consensus meeting of the European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO) and the International Foundation for Osteoporosis (IOF).

The place of calcium supplementation, with or without concomitant vitamin D supplementation, has been much debated in terms of both efficacy and safety. There have been numerous trials and meta-analyses of supplementation for fracture reduction, and associations with risk of myocardial infarction have been suggested in recent years. In this report, the product of an expert consensus meeting of the European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO) and the International Foundation for Osteoporosis (IOF), we review the evidence for the value of calcium supplementation, with or without vitamin D supplementation, for healthy musculoskeletal ageing. We conclude that (1) calcium and vitamin D supplementation leads to a modest reduction in fracture risk, although population-level intervention has not been shown to be an effective public health strategy; (2) supplementation with calcium alone for fracture reduction is not supported by the literature; (3) side effects of calcium supplementation include renal stones and gastrointestinal symptoms; (4) vitamin D supplementation, rather than calcium supplementation, may reduce falls risk; and (5) assertions of increased cardiovascular risk consequent to calcium supplementation are not convincingly supported by current evidence. In conclusion, we recommend, on the basis of the current evidence, that calcium supplementation, with concomitant vitamin D supplementation, is supported for patients at high risk of calcium and vitamin D insufficiency, and in those who are receiving treatment for osteoporosis.

Determinants of vitamin D supplementation prescription in nursing homes: a survey among general practitioners.

SUMMARY: A total of 119 GPs participated to a survey aimed to assess the profile and determinants of vitamin D supplementation prescription in nursing homes. Among the respondent GPs, 65 (54.6%) systematically prescribe vitamin D to their institutionalized patients and the 54 (45.4%) others prescribe only sometimes. INTRODUCTION: The aim of this study is to assess the profile and determinants of vitamin D supplementation prescription in nursing homes. METHODS: General practitioners (GPs) having at least one patient in a nursing home in Liège, Belgium, were asked to complete the survey. RESULTS: A total of 119 GPs participated in the survey. Among the respondent GPs, 65 (54.6 %) systematically prescribe vitamin D to their institutionalized patients and the 54 (45.4%) others prescribe only sometimes. The main reasons for prescribing vitamin D cited by GPs who do so systematically are as follows: because they believe nursing home residents are mostly deficient in vitamin D status (92.1%), because they believe that vitamin D supplementation prevents osteoporotic fractures (77.8%), and because vitamin D supplementation is recommended by various scientific societies (38.1%). GPs who only prescribe vitamin D supplementation in some patients mainly do so following a diagnosis of osteoporosis (82.4%), on the basis the 25(OH)D level (78.4%), in the case of history of fracture (54.9%) or after a recent fracture (43.4%). Surprisingly, 16 physicians (31.4%) only prescribe vitamin D when they think of it. Interestingly, while 40.7% of GPs always prescribe the same dose of vitamin D, the remaining 59.3% prescribe a dose that will mainly depend on the results of the 25(OH)D level (94.0%), the patient's bone health (49.3%), or history of fracture (43.3%). CONCLUSIONS: More than half of GPs systematically prescribe vitamin D to their patients living in nursing homes. The other GPs usually prescribe vitamin D following the result of the vitamin D status or after a diagnosis of osteoporosis.

Recommendations for an update of the 2010 European regulatory guideline on clinical investigation of medicinal products used in the treatment of osteoarthritis and reflections about related clinically relevant outcomes: expert consensus statement.

OBJECTIVE: The European Society on Clinical and Economic aspects of Osteoporosis and Osteoarthritis (ESCEO) organised a working group to evaluate the need for updating the current European guideline on clinical investigation of drugs used in the treatment of osteoarthritis (OA). DESIGN: Areas of potential attention were identified and the need for modifications, update or clarification was examined. Proposals were then developed based on literature reviews and through a consensus process. RESULTS: It was agreed that the current guideline overall still reflects the current knowledge in OA, although two possible modifications were identified. The first relates to the number and timing of measurements required as primary endpoints during clinical trials of symptom-relieving drugs, either drugs with rapid onset of action or slow acting drugs. The suggested modifications are intended to take into consideration the time related clinical need and expected time response to these drugs - i.e., a more early effect for the first category in addition to the maintenance of effect, a more continuous benefit over the long-term for the latter - in the timing of assessments. Secondly, values above which a benefit over placebo should be considered clinically relevant were considered. Based on literature reviews, the most consensual values were determined for primary endpoints of both symptom-relieving drugs (i.e., pain intensity on a visual analogue scale (VAS)) and disease-modifying drugs (i.e., radiographic joint-space narrowing). CONCLUSIONS: This working document might be considered by the European regulatory authorities in a future update of the guideline for the registration of drugs in OA.

[Treatment of post-menopausic osteoporosis: what's new in 2014?]. / Traitement de l'ostéoporose post-ménopausique: quoi de neuf en 2014?

Management of osteoporosis involves both non pharmacological approaches, including changes in lifestyle and dietary habits combined, in patients at high risk of fracture or presenting with an established osteoporosis, to the use of drugs. Besides supplementation in calcium and vitamin D (at daily doses of 1 gr and 800 IU) in patients whose dietary intakes do not cover the recommended daily allowances, medications to be used for the management of osteoporosis may include inhibitors of bone resorption (bisphosphonates, denosumab and selective estrogen receptor modulators), stimulators of bone formation (teriparatide) or chemical entities decreasing bone resorption and stimulating bone formation (strontium ranelate). The selection of a particular medication, for a single individual patient, will depend on the severity of the disease as well as on the patient's believes and expectations. Local, skeletal and systemic tolerance of the various drugs should also be taken into account.

Management of osteoporosis of the oldest old.

UNLABELLED: This consensus article reviews the diagnosis and treatment of osteoporosis in geriatric populations. Specifically, it reviews the risk assessment and intervention thresholds, the impact of nutritional deficiencies, fall prevention strategies, pharmacological treatments and their safety considerations, the risks of sub-optimal treatment adherence and strategies for its improvement. INTRODUCTION: This consensus article reviews the therapeutic strategies and management options for the treatment of osteoporosis of the oldest old. This vulnerable segment (persons over 80 years of age) stands to gain substantially from effective anti-osteoporosis treatment, but the under-prescription of these treatments is frequent. METHODS: This report is the result of an ESCEO (European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis) expert working group, which explores some of the reasons for this and presents the arguments to counter these beliefs. The risk assessment of older individuals is briefly reviewed along with the differences between some intervention guidelines. The current evidence on the impact of nutritional deficiencies (i.e. calcium, protein and vitamin D) is presented, as are strategies to prevent falls. One possible reason for the under-prescription of pharmacological treatments for osteoporosis in the oldest old is the perception that anti-fracture efficacy requires long-term treatment. However, a review of the data shows convincing anti-fracture efficacy already by 12 months. RESULTS: The safety profiles of these pharmacological agents are generally satisfactory in this patient segment provided a few precautions are followed. CONCLUSION: These patients should be considered for particular consultation/follow-up procedures in the effort to convince on the benefits of treatment and to allay fears of adverse drug reactions, since poor adherence is a major problem for the success of a strategy for osteoporosis and limits cost-effectiveness.

Vitamin D supplementation in elderly or postmenopausal women: a 2013 update of the 2008 recommendations from the European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis (ESCEO).

BACKGROUND: Vitamin D insufficiency has deleterious consequences on health outcomes. In elderly or postmenopausal women, it may exacerbate osteoporosis. SCOPE: There is currently no clear consensus on definitions of vitamin D insufficiency or minimal targets for vitamin D concentrations and proposed targets vary with the population. In view of the potential confusion for practitioners on when to treat and what to achieve, the European Society for Clinical and Economic Aspects of Osteoporosis and Osteoarthritis (ESCEO) convened a meeting to provide recommendations for clinical practice, to ensure the optimal management of elderly and postmenopausal women with regard to vitamin D supplementation. FINDINGS: Vitamin D has both skeletal and extra-skeletal benefits. Patients with serum 25-hydroxyvitamin D (25-(OH)D) levels <50 nmol/L have increased bone turnover, bone loss, and possibly mineralization defects compared with patients with levels >50 nmol/L. Similar relationships have been reported for frailty, nonvertebral and hip fracture, and all-cause mortality, with poorer outcomes at <50 nmol/L. CONCLUSION: The ESCEO recommends that 50 nmol/L (i.e. 20 ng/mL) should be the minimal serum 25-(OH)D concentration at the population level and in patients with osteoporosis to ensure optimal bone health. Below this threshold, supplementation is recommended at 800 to 1000 IU/day. Vitamin D supplementation is safe up to 10,000 IU/day (upper limit of safety) resulting in an upper limit of adequacy of 125 nmol/L 25-(OH)D. Daily consumption of calcium- and vitamin-D-fortified food products (e.g. yoghurt or milk) can help improve vitamin D intake. Above the threshold of 50 nmol/L, there is no clear evidence for additional benefits of supplementation. On the other hand, in fragile elderly subjects who are at elevated risk for falls and fracture, the ESCEO recommends a minimal serum 25-(OH)D level of 75 nmol/L (i.e. 30 ng/mL), for the greatest impact on fracture.

Perception, knowledge, and use by general practitioners of Belgium of a new WHO tool (FRAX) to assess the 10-year probability of fracture.

The FRAX tool that calculates the 10-year probability of having a fracture has recently been validated for Belgium. Little is known about the perception and knowledge that GPs have about this tool in their daily practice. A survey has been conducted as part of a screening campaign for various diseases. The primary objective of the present study was to assess the perception and the knowledge of the FRAX tool by GPs. The secondary objective was to assess the impact of an information brochure about the FRAX tool on these outcomes. The survey was sent to a sample of 700 GPs after only half of them had received the information brochure. The survey results show that, out of the 193 doctors who responded to the survey, one-third know the FRAX tool but less than 20 % use it in their daily clinical practice. Among those who use it, the FRAX tool is largely seen as a complementary but not as an essential tool in the diagnosis or in the management of osteoporosis. It appears that the brochure could improve the knowledge of the FRAX tool but it would not be more efficient on its use in daily practice than the other sources of information. At present, the use of the FRAX tool in Belgium is limited but an information brochure could have a positive impact on the knowledge of the FRAX tool.

Effect of collagen hydrolysate in articular pain: a 6-month randomized, double-blind, placebo controlled study.

OBJECTIVE: Evaluation of the efficacy and safety of a food supplement made of collagen hydrolysate 1200 mg/day versus placebo during 6 months, in subjects with joint pain at the lower or upper limbs or at the lumbar spine. DESIGN: Comparative double-blind randomized multicenter study in parallel groups. SETTING: 200 patients of both genders of at least 50 years old with joint pain assessed as ≥30 mm on a visual analogical scale (VAS). INTERVENTION: Collagen hydrolysate 1200 mg/day or placebo during 6 months. MAIN OUTCOME MEASURE: Comparison of the percentage of clinical responder between the active collagen hydrolysate group and the placebo group after 6 months of study. A responder subject was defined as a subject experiencing a clinically significant improvement (i.e. by 20% or more) in the most painful joint using the VAS score. All analyses were performed using an intent-to-treat procedure. RESULTS: At 6 months, the proportion of clinical responders to the treatment, according to VAS scores, was significantly higher in the collagen hydrolysate (CH) group 51.6%, compared to the placebo group 36.5% (p<0.05). However, there was no significant difference between groups at 3 months (44.1% vs. 39.6%, p=0.53). No significant difference in terms of security and tolerability was observed between the two groups. CONCLUSIONS: This study suggests that collagen hydrolysate 1200 mg/day could increase the number of clinical responders (i.e. improvement of at least 20% on the VAS) compared to placebo. More studies are needed to confirm the clinical interest of this food supplement.

Health claims assessment in the field of joint and cartilage: a consensus viewpoint of the Group for the Respect of Ethics and Excellence in Science.

INTRODUCTION: In 2006, the European Parliament and Council issued a regulation (No. 1924/2006) for the nutrition and health claims made on foods, including food supplements. According to the regulation, the use of nutrition and health claims shall only be permitted if the substance in respect of which the claim is made has been shown to have a beneficial nutritional or physiological effect. In the field of joint and cartilage health, there is no clear scientific-based definition of the nature of such a beneficial nutritional or physiological effect. The objective of this paper is to scientifically define the possible content of health claims related to joint and cartilage health and to provide scientific guidelines for the design of clinical studies which need to be adopted to substantiate such health claims. METHODS: Literature review up to September 2011 followed by a consensus expert discussion organized by the Group for the Respect of Ethics and Excellence in Science (GREES). RESULTS: In line with the general principles of the PASSCLAIM and the Codex recommendations, the GREES identified four acceptable health claims related to joint and cartilage health based on the effects on discomfort, joint and cartilage structural integrity or risk factors for joint and cartilage diseases. The GREES considers that randomized controlled trials on a relevant outcome is the best design to assess health claims. Moreover, animal studies could also be of interest to substantiate some health claims, to assess the clinical relevance of endpoints used in human studies or to extrapolate data obtained in patients to the target (apparently) healthy population. CONCLUSION: According to the methodology and biomarkers used in the study and whether or not additional animal studies are provided to support the claim, various health claims can be acceptable in the field of joint and cartilage health.

Non-pharmacological management of osteoporosis: a consensus of the Belgian Bone Club.

This consensus article reviews the various aspects of the non-pharmacological management of osteoporosis, including the effects of nutriments, physical exercise, lifestyle, fall prevention, and hip protectors. Vertebroplasty is also briefly reviewed. Non-pharmacological management of osteoporosis is a broad concept. It must be viewed as an essential part of the prevention of fractures from childhood through adulthood and the old age. The topic also includes surgical procedures for the treatment of peripheral and vertebral fractures and the post-fracture rehabilitation. The present document is the result of a consensus, based on a systematic review and a critical appraisal of the literature. Diets deficient in calcium, proteins or vitamin D impair skeletal integrity. The effect of other nutriments is less clear, although an excessive consumption of sodium, caffeine, or fibres exerts negative effects on calcium balance. The deleterious effects of tobacco, excessive alcohol consumption and a low BMI are well accepted. Physical activity is of primary importance to reach optimal peak bone mass but, if numerous studies have shown the beneficial effects of various types of exercise on bone mass, fracture data as an endpoint are scanty. Fall prevention strategies are especially efficient in the community setting, but less evidence is available about their effectiveness in preventing fall-related injuries and fractures. The efficacy of hip protectors remains controversial. This is also true for vertebroplasty and kyphoplasty. Several randomized controlled studies had reported a short-term advantage of vertebroplasty over medical treatment for pain relief, but these findings have been questioned by recent sham-controlled randomized clinical studies.

Relationship between bone mineral density changes and risk of fractures among patients receiving calcium with or without vitamin D supplementation: a meta-regression.

UNLABELLED: Surrogate measures of fracture risk, such as effects on bone mineral density, may be of great interest to assess the efficacy of available osteoporosis treatments.Our results suggest that bone mineral density (BMD)changes cannot be used as a surrogate of anti-fracture efficacy, among patients receiving calcium, with or without vitamin D. INTRODUCTION: The purpose of this study is to examine the association between changes in bone mineral density with reduction in the risk of fractures in patients receiving calcium with or without vitamin D. METHODS: We selected all randomized placebo-controlled clinical trials of calcium with or without vitamin D supplementation. To be included in this analysis, the studies were required to report both BMD (hip/proximal femur and/or lumbar spine) and the incidence of fractures. Meta-regression analyses were used to examine the associations of changes in BMD with reduction in risk of fracture over the duration of each study. The change in BMD was the difference between changes (from baseline) observed in the active treatment group and placebo group. RESULTS: A total of 15 randomized trials (n=47,365) were identified, most of whom (77%) came from the Women's Health Initiative trial. Results show that larger increases in BMD at the lumbar spine were not associated with greater reduction in fracture risk. Concerning hip BMD changes,we found a statistically significant relationship between hip BMD changes and reduction in risk. However, results were not quite significant after excluding the both largest studies, in which BMD changes were measured in very small subset of patients. These points may have largely biased our results. CONCLUSIONS: In conclusion, there was no evidence of a relationship between BMD changes and reduction in risk of fractures among patients receiving calcium with or without vitamin D supplementation. Calcium and/or Vitamin D may reduce fracture rates through a mechanism independent of bone density.
