Older adult women with chronic anorexia nervosa: heterogeneous adaptation to undernutrition over time.

INTRODUCTION: Anorexia nervosa (AN) in older adult women is primarily described through reviews or case reports focusing on psychiatric traits, with no comprehensive studies evaluating their complete nutritional and hormonal profiles. This study aimed to describe a group of women with anorexia nervosa aged above 35 years old (AN35), and compare them with young women with anorexia nervosa (ANY) and normal-weight control participants. METHOD: Anthropometric, metabolic, nutritional, and psychiatric parameters were collected and compared among three groups of women: 50 AN35, 37 ANY, and 38 controls. RESULTS: AN35 exhibited a mean disease duration of 271 ± 19 months, with 94% chronic forms and 58% restrictive types. Despite having similar BMI as ANY, AN35 displayed more altered parameters, including higher liver enzymes (p = 0.007), free T3 (p = 0.0046) and leptin (p < 0.0001); and lower albumin (p = 0.0029), and white cells (p < 0.0001). AN35 showed significant heterogeneity in hormonal adaptation, such as free T3. Half of the patients aged above 51 years revealed high gonadotropin levels despite being undernourished. Additionally, AN35 groups presented with 50% of bones fractures, decreased T-scores under -2.5 (p < 0.0001 for femoral), and altered micro architectural HRPQT parameters compared to ANY. CONCLUSION: Anorexia nervosa in older adult women is predominantly chronic. Nutritional parameters changes with age suggests a significant heterogeneity and possible adaptation of energy balance and bodyweight set point for others. Complications may be severe, altering the quality of life, and sometimes potentially lethal. These findings highlight the potential adaptation of energy balance with age, and should assist clinicians in clinical practice.

Percutaneous Fixation with Internal Cemented Screws for Iliac Lytic Bone Metastases: Assessment of Pain and Quality of Life on Long Term Follow-up.

PURPOSE: To assess effectiveness on pain, quality of life and late adverse events of percutaneous fixation with internal cemented screw (FICS) among patients with iliac lytic bone metastases with or without pathological fractures. MATERIALS AND METHODS: This retrospective exploratory study analyzed FICS procedures on iliac osteolytic bone lesions with and without pathological fracture performed from July 2019 to January 2022 in one tertiary level university hospital. The procedure were performed under general anesthesia, and were CT and fluoroscopically guided. Numerical Pain Rate Score (NPRS), mean EuroQol visual analogue scale (EQ VAS), morphine consumption, walking ability, walking perimeter and presence of walking aids and the appearance of complications were evaluated. RESULTS: Nineteen procedures among 18 patients were carried out with a mean follow up time of 243.3 ± 243.2 days. The mean of the maximum NPRS decreased from 8.4 ± 1.3 to 2.2 ± 3.1 at 1 month (p < 0.01) and remained between 1.3 and 4.1 during a follow-up consultation period of 3-24 months. The mean EQ VAS rose from 42.0 ± 12.5 to 57.3 ± 13.9 at 1 month (p < 0.01) follow-up and remained between 55.8 and 62.5 thereafter. No patient scores returned to pre-procedure levels during follow-up. Mean morphine use decreased from 111.1 ± 118.1 to 57.8 ± 70.3 mg/d at 1 month (p > 0.05) follow-up. No late adverse events were reported. CONCLUSION: Percutaneous FICS is a safe procedure with fast and long-standing effect on pain, mobility and quality of life. It can be used as a complement to the known analgesic therapeutic arsenal for bone metastases.

[IPA in primary care: a new gateway to the healthcare system]. / L'IPA en soins primaires : une nouvelle porte d'entrée dans le système de santé.

In France, the supply of healthcare services remains insufficient to meet the growing needs of the population, which has prompted the legislator to authorize direct access to certain professionals, in particular advanced practice nurses (APNs) working in coordinated practice structures. This article details an innovative multi-professional pathway in a nursing home, where the APN takes direct charge of people without a general practitioner, with the aim of improving their access to care and reintegrating them into the healthcare system.

Narrative Review of Effects of Glucagon-Like Peptide-1 Receptor Agonists on Bone Health in People Living with Obesity.

Glucagon-like peptide-1 Receptor agonists (GLP-1Ras) such as liraglutide and semaglutide have been recently approved as medications for chronic weight management in people living with obesity (PwO); GLP-1 may enhance bone metabolism and improve bone quality. However, the effects of GLP-1Ras on skeletal health remain to be determined and that's the purpose of this narrative review. Nevertheless, bone consequences of intentional weight loss interventions in PwO are well known: (i) significant weight loss induced by caloric restriction and bariatric surgery results in accelerated bone turnover and bone loss, and (ii) unlike caloric restriction interventions, PwO experience a substantial deterioration in bone microarchitecture and strength associated with an increased risk of fracture after bariatric surgery especially malabsorptive procedures. Liraglutide seems to have a positive effect on bone material properties despite significant weight loss in several rodent models. However, most of positive effects on bone mineral density and microarchitecture were observed at concentration much higher than approved for obesity care in humans. No data have been reported in preclinical models with semaglutide. The current evidence of the effects of GLP-1Ra on bone health in PwO is limited. Indeed, studies on the use of GLP-1Ra mostly included patients with diabetes who were administered a dose used in this condition, did not have adequate bone parameters as primary endpoints, and had short follow-up periods. Further studies are needed to investigate the bone impact of GLP-1Ra, dual- and triple-receptor agonists for GLP-1, glucose-dependent insulin releasing polypeptide (GIP), and glucagon in PwO.

Dietary supplementation with nacre reduces cortical bone loss in aged female mice.

Aging is associated with detrimental bone loss leading to fragility fractures in both men and women. Notably, a majority of bone loss with aging is cortical, as well as a large number of fractures are non-vertebral and at the non-hip sites. Nacre is a product of mollusks composed of calcium carbonate embedded in organic components. As our previous study demonstrated the protective effect of nacre supplementation on trabecular bone loss in ovariectomized rats, we sought to evaluate the effect of dietary nacre on bone loss related to aging in female mice which do not suffer true menopause as observed in women. The current study compared the effect of a 90-day long nacre-supplemented diet to that of Standard or CaCO3 diets on both bone mass and strength in 16-month-old C57BL/6 female mice. Multiple approaches were performed to assess the microarchitecture and mechanical properties of long bones, analyze trabecular histomorphometry, and measure bone cell-related gene expressions, and bone turnover markers. In the cortex, dietary nacre improved cortical bone strength in line with lower expression levels of genes reflecting osteoclasts activity compared to Standard or CaCO3 diets (p < 0.05). In the trabeculae, nacre-fed mice were characterized by a bone remodeling process more active than the other groups as shown by greater histomorphometric parameters and osteoblast-related gene expressions (p < 0.05). But these differences were not exhibited at the level of the trabecular microarchitecture at this age. Collectively, these data suggest that dietary nacre should be a potential candidate for reducing aging-associated cortical bone loss in the elderly.

Advanced practice nurse management in multiple myeloma treated with oral therapy.

INTRODUCTION: Therapeutic approaches in Multiple Myeloma (MM) have considerably changed over the last few years, with effective oral chemotherapy and continuous treatment. In this context, the objective of this study was to examine the circuitry of an advanced practitioner nurse (APN)-led intervention that provided supportive care for MM patients treated with oral chemotherapy. METHODS: This population-based study was conducted at the hematology department - Institut de Cancérologie Lucien Neuwirth (ICLN, Saint-Priest-en-Jarez), from April 2017 to September 2020. A follow-up program was established with a specialized APN in oncology. RESULTS: All APN interventions were recorded, representing 1240 phone calls and 162 consultations for 42 MM patients. Eighty-two calls were referred to the physician with 45 consultations triggered. Most of the calls were frequent within the few first months, with a high request for information and reassurance, especially for treatment-naive or relapsed patients. In our study, the APN was able to manage multiple side effects through care organization (i.e., hospitalizations, transfusions) and a careful coordination between the primary care team and the hospital. DISCUSSION: In order to respond to the high need for care pathway and safety improvement, especially in elderly population, we have initiated an original follow-up by an APN for MM patients treated with oral chemotherapy. While the role of APN has become prominent in the oncology field in recent years, its holistic approach has to be emphasized in further studies to bring a comprehensive perspective to health care coordination in the future.

Proteomics analyses of human plasma reveal triosephosphate isomerase as a potential blood marker of methotrexate resistance in rheumatoid arthritis.

OBJECTIVES: To assess differentially expressed blood proteins between patients with active rheumatoid arthritis (RA) and patients in remission after methotrexate (MTX) treatment, with the aim of identifying a biomarker of methotrexate resistance (MTXR). METHODS: Two populations of RA patients treated with a stable dose of subcutaneous MTX for at least 3 months were constituted according to the DAS28: remission (DAS28 < 2.6; n = 24) and active disease (DAS28 > 3.2; n = 32). The two groups of RA patients were homogeneous regarding their epidemiological characteristics, except for the duration of treatment which was longer in the remission group. After collection of a blood sample, plasma protein digestion was performed, followed by untargeted proteomics analysis. Then, a targeted analysis was performed to confirm the results of the untargeted approach. RESULTS: Untargeted proteomics analysis revealed 8 plasma proteins differentially expressed between the two groups of patients. Among them, triosephosphate isomerase (TPI-1) and glucose-6-phosphate isomerase (GPI), which are main actors of glycolysis, were found down-regulated in the active group. This result was confirmed for TPI-1 in the targeted proteomics analysis. CONCLUSIONS: A first step was achieved in the search for biomarker of MTXR with identification of two actors of glycolysis (TPI-1 and GPI). The next step will be to confirm these results in a larger cohort, including samples from treatment-naive patients, to assess the predictive potential of these protein markers.

Factors associated with COVID-19 severity in patients with spondyloarthritis: Results of the French RMD COVID-19 cohort.

OBJECTIVES: The objective of the current study was to evaluate the severity of COVID-19 and identify factors associated with severe disease outcomes in patients with spondyloarthritis (SpA), a chronic inflammatory rheumatic and musculoskeletal disease (RMD). METHODS: We utilized patient data from the French national multicenter RMD COVID-19 cohort (NCT04353609). The primary outcome was to describe COVID-19 characteristics in patients with SpA based on disease severity of COVID-19 (mild, moderate or severe) with serious infection including moderate and severe cases. The secondary outcome was to identify the factors associated with serious COVID-19 classification. RESULTS: Among the 626 patients with SpA (56% female, mean age 49±14 years) from the French RMD cohort, COVID-19 severity was mild in 508 (81%), moderate in 93 (15%), and severe in 25 (4%) patients. Clinical signs and symptoms of COVID-19 were reported in 587 (94%) patients, with the most frequent presented symptom of fever (63%) and cough (62%), followed by flu-like symptoms (53%), agueusia (39%), anosmia (37%), dyspnea (32%) and diarrhea (19.9%). COVID-19 severity was associated with corticosteroid therapy (OR=3.08 [95% CI: 1.44-6.58], P=0.004) and age (OR=1.06 [95% CI: 1.04-1.08], P<0.001) while use of tumor necrosis factor inhibitor (TNFi, OR=0.27 [95% CI: 0.09-0.78], P=0.01) was associated with less severe disease. We did not identify an association between NSAID use and COVID-19 severity. CONCLUSIONS: In this study, the majority of patients with SpA had a favorable COVID-19 outcome. We confirmed age and corticosteroids therapy had a negative impact on disease outcomes while TNFi use was protective.

Fracture risk reduction and safety by osteoporosis treatment compared with placebo or active comparator in postmenopausal women: systematic review, network meta-analysis, and meta-regression analysis of randomised clinical trials.

OBJECTIVE: To review the comparative effectiveness of osteoporosis treatments, including the bone anabolic agents, abaloparatide and romosozumab, on reducing the risk of fractures in postmenopausal women, and to characterise the effect of antiosteoporosis drug treatments on the risk of fractures according to baseline risk factors. DESIGN: Systematic review, network meta-analysis, and meta-regression analysis of randomised clinical trials. DATA SOURCES: Medline, Embase, and Cochrane Library to identify randomised controlled trials published between 1 January 1996 and 24 November 2021 that examined the effect of bisphosphonates, denosumab, selective oestrogen receptor modulators, parathyroid hormone receptor agonists, and romosozumab compared with placebo or active comparator. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Randomised controlled trials that included non-Asian postmenopausal women with no restriction on age, when interventions looked at bone quality in a broad perspective. The primary outcome was clinical fractures. Secondary outcomes were vertebral, non-vertebral, hip, and major osteoporotic fractures, all cause mortality, adverse events, and serious cardiovascular adverse events. RESULTS: The results were based on 69 trials (>80 000 patients). For clinical fractures, synthesis of the results showed a protective effect of bisphosphonates, parathyroid hormone receptor agonists, and romosozumab compared with placebo. Compared with parathyroid hormone receptor agonists, bisphosphonates were less effective in reducing clinical fractures (odds ratio 1.49, 95% confidence interval 1.12 to 2.00). Compared with parathyroid hormone receptor agonists and romosozumab, denosumab was less effective in reducing clinical fractures (odds ratio 1.85, 1.18 to 2.92 for denosumab v parathyroid hormone receptor agonists and 1.56, 1.02 to 2.39 for denosumab v romosozumab). An effect of all treatments on vertebral fractures compared with placebo was found. In the active treatment comparisons, denosumab, parathyroid hormone receptor agonists, and romosozumab were more effective than oral bisphosphonates in preventing vertebral fractures. The effect of all treatments was unaffected by baseline risk indicators, except for antiresorptive treatments that showed a greater reduction of clinical fractures compared with placebo with increasing mean age (number of studies=17; ß=0.98, 95% confidence interval 0.96 to 0.99). No harm outcomes were seen. The certainty in the effect estimates was moderate to low for all individual outcomes, mainly because of limitations in reporting, nominally indicating a serious risk of bias and imprecision. CONCLUSIONS: The evidence indicated a benefit of a range of treatments for osteoporosis in postmenopausal women for clinical and vertebral fractures. Bone anabolic treatments were more effective than bisphosphonates in the prevention of clinical and vertebral fractures, irrespective of baseline risk indicators. Hence this analysis provided no clinical evidence for restricting the use of anabolic treatment to patients with a very high risk of fractures.

Obesity related to metabolic syndrome: comparison of obesity indicators in an older french population.

OBJECTIVES: Metabolic syndrome (MS) represents a cluster of metabolic abnormalities. Insulin resistance is a major component of the syndrome. We analyze in this study the relationship between body fat composition and MS in comparison to usual obesity indicators in an older adult population. DESIGN: The PROgnostic indicator OF cardiovascular and cerebrovascular events (PROOF) study is a prospective longitudinal community cohort study among the inhabitants of Saint-Etienne, France. METHODS: The study is a cohort study of 1011 subjects, mean age 65.6 ± 0.8 years old at inclusion, recruited from the electoral list of the town in 2000. Among them, 806 subjects realized a Dual-energy X-ray absorptiometry (DXA) used to evaluate body fat and lean mass repartition. We evaluate biological metabolic parameters according to usual techniques. The indices of obesity were calculated according to standard formula. MS presence and its components were simultaneously evaluated. RESULTS: All obesity parameters were significantly higher (p < 0.0001) in subjects suffering metabolic syndrome as compared to those without. Body fat index (BFI) presented a stronger correlation to total fat mass, trunk fat mass and body adiposity index (BAI). The correlations between body indices and metabolic components showed that body mass index (BMI) and waist circumference were more strongly associated with BFI as compared to BAI and total fat mass. According to logistic regression analysis, only the waist-hip ratio (WHR) demonstrated a significant association with MS severity (p < 0.0001). CONCLUSIONS: Among the obesity indices, BFI and BAI represented the best indicators to characterize global obesity while WHR only is highly predictive of metabolic syndrome presence and severity. The BAI indicator is an alternative for measuring obesity. Comparison of long-term impact of such markers on cardiovascular morbidity and mortality is now questioned.

Does Adjunction of Autologous Osteoblastic Cells Improve the Results of Core Decompression in Early-stage Femoral Head Osteonecrosis? A Double-blind, Randomized Trial.

BACKGROUND: Osteonecrosis of the femoral head (ONFH) is a disabling disease that can ultimately progress to collapse of the femoral head, often resulting in THA. Core decompression of the femoral head combined with cell therapies have shown beneficial effects in previous clinical studies in patients with early-stage (Association Research Circulation Osseous [ARCO] Stage I and II) ONFH. However, high-quality evidence confirming the efficacy of this treatment modality is still lacking. QUESTIONS/PURPOSES: (1) Is core decompression combined with autologous osteoblastic cell transplantation superior to core decompression with placebo implantation in relieving disease-associated pain and preventing radiologic ONFH progression in patients with nontraumatic early-stage ONFH? (2) What adverse events occurred in the treatment and control groups? METHODS: This study was a Phase III, multicenter, randomized, double-blind, controlled study conducted from 2011 to 2019 (ClinicalTrails.gov registry number: NCT01529008). Adult patients with ARCO Stage I and II ONFH were randomized (1:1) to receive either core decompression with osteoblastic cell transplantation (5 mL with 20 x 10 6 cells/mL in the study group) or core decompression with placebo (5 mL of solution without cells in the control group) implantation. Thirty percent (68 of 230) of the screened patients were eligible for inclusion in the study; of these, 94% (64 of 68) underwent a bone marrow harvest or sham procedure (extended safety set) and 79% (54 of 68) were treated (study group: 25 patients; control group: 29). Forty-nine patients were included in the efficacy analyses. Similar proportions of patients in each group completed the study at 24 months of follow-up (study group: 44% [11 of 25]; control: 41% [12 of 29]). The study and control groups were comparable in important ways; for example, in the study and control groups, most patients were men (79% [27 of 34] and 87% [26 of 30], respectively) and had ARCO Stage II ONFH (76% [19 of 25] and 83% [24 of 29], respectively); the mean age was 46 and 45 years in the study and control groups, respectively. The follow-up period was 24 months post-treatment. The primary efficacy endpoint was the composite treatment response at 24 months, comprising the clinical response (clinically important improvement in pain from baseline using the WOMAC VA3.1 pain subscale, defined as 10 mm on a 100-mm scale) and radiologic response (the absence of progression to fracture stage [≥ ARCO Stage III], as assessed by conventional radiography and MRI of the hips). Secondary efficacy endpoints included the percentages of patients achieving a composite treatment response, clinical response, and radiologic response at 12 months, and the percentage of patients undergoing THA at 24 months. We maintained a continuous reporting system for adverse events and serious adverse events related to the study treatment, bone marrow aspiration and sham procedure, or other study procedures throughout the study. A planned, unblinded interim analysis of efficacy and adverse events was completed at 12 months. The study was discontinued because our data safety monitoring board recommended terminating the study for futility based on preselected futility stopping rules: conditional power below 0.20 and p = 0.01 to detect an effect size of 10 mm on the 100-mm WOMAC VA3.1 pain subscale (improvement in pain) and the absence of progression to fracture (≥ ARCO Stage III) observed on radiologic assessment, reflecting the unlikelihood that statistically beneficial results would be reached at 24 months after the treatment. RESULTS: There was no difference between the study and control groups in the proportion of patients who achieved a composite treatment response at 24 months (61% [14 of 23] versus 69% [18 of 26]; p = 0.54). There was no difference in the proportion of patients with a treatment response at 12 months between the study and control groups (14 of 21 versus 15 of 23; p = 0.92), clinical response (17 of 21 versus 16 of 23; p = 0.38), and radiologic response (16 of 21 versus 18 of 23; p = 0.87). With the numbers available, at 24 months, there was no difference in the proportion of patients who underwent THA between the study and control groups (24% [six of 25] versus 14% [four of 29]). There were no serious adverse events related to the study treatment, and only one serious adverse event (procedural pain in the study group) was related to bone marrow aspiration. Nonserious adverse events related to the treatment were rare in the study and control groups (4% [one of 25] versus 14% [four of 29]). Nonserious adverse events related to bone marrow or sham aspiration were reported by 15% (five of 34) of patients in the study group and 7% (two of 30) of patients in the control group. CONCLUSION: Our study did not show any advantage of autologous osteoblastic cells to improve the results of core decompression in early-stage (precollapse) ONFH. Adverse events related to treatment were rare and generally mild in both groups, although there might have been a potential risk associated with cell expansion. Based on our findings, we do not recommend the combination of osteoblastic cells and core decompression in patients with early-stage ONFH. Further, well-designed studies should be conducted to explore whether other treatment modalities involving a biological approach could improve the overall results of core decompression. LEVEL OF EVIDENCE: Level II, therapeutic study.

COVID-19 presentation and outcomes in patients with inflammatory rheumatic and musculoskeletal diseases receiving IL6-receptor antagonists prior to SARS-CoV-2 infection.

Objective: COVID-19 outcome may be less favourable in patients with inflammatory rheumatic and musculoskeletal diseases (RMD) receiving immunosuppressive therapy. We aimed to investigate whether RMD patients on anti-IL6 therapy prior to SARS-CoV-2 infection have less severe disease and better outcomes of COVID-19. Methods: We conducted a retrospective national, multicentre cohort study using data from the French RMD COVID-19 cohort. We compared the severity and outcome of highly suspected or confirmed COVID-19 infection in RMD patients previously treated with tocilizumab or sarilumab (anti-IL6 group) with patients who did not receive anti-IL6 therapy (no anti-IL6 group). Results: Data were collected for 1883 patients with mean age of 55.2 years [SD 16.7] and 1256 (66.7%) female. Two hundred ten (11.1%) developed severe COVID-19 and 115 (6.4%) died. After adjusting for potential confounding factors, severe COVID-19 was less frequent in the anti-IL6 group compared with the no anti-IL6 group (aOR for moderate vs. mild severity, 0.23 [95% CI, 0.10 to 0.54], p ≤ 0.01 and aOR for severe vs. mild, 0.29 [95% CI, 0.10 to 0.81], p ≤ 0.01). No significant differences were found for the evolution of COVID-19 between the anti-IL6 group and the no anti-IL6 group (aOR for recovery with sequelae vs recovery without sequelae, 0.78 [95% CI, 0.41 to 1.48] and aOR for death vs recovery without sequelae, 0.29 [95% CI, 0.07 to 1.30]). Conclusion: RMD patients receiving anti-IL6 therapy prior to SARS-CoV-2 infection have less severe forms of COVID-19. No difference was observed in COVID-19 evolution, i.e., sequelae or death, between the groups.

Dietary recommendations in the prevention and treatment of osteoporosis.

INTRODUCTION: This article presents the initial recommendations of the French Rheumatology Society (Société Française de Rhumatologie - SFR) and the Osteoporosis Research and Information Group (Groupe de Recherche et d'Informations sur les Ostéoporoses - GRIO) on the role of diet in the prevention and treatment of osteoporosis. METHODS: The recommendations were produced by a working group composed of rheumatologists, physician nutrition specialists and a geriatrician. Fifteen (15) questions pertaining to "daily practices" were preselected by the working group. For the literature review, the working group focussed mainly on the effects of diet on bone mineral density (BMD) and fractures, and primarily on meta-analyses of longitudinal studies and dietary intervention studies. RESULTS: A Mediterranean-type diet and the daily consumption of 2 to 3 dairy products are recommended. Together, these provide the calcium and "high quality" protein required to maintain a normal calcium-phosphorus balance and bone metabolism, and are associated with lower fracture risk. Conversely, unbalanced Western diets, vegan diets, weight-loss diets in non-overweight individuals, alcohol consumption and daily consumption of sodas are advised against. In terms of the beneficial effects on bone mineral density and fracture risk, current scientific data are either insufficient or too divergent to recommend increasing or restricting the consumption of tea or coffee, vitamins other than vitamin D, vitamin D-enriched or phytoestrogen-rich foods, calcium-enriched plant-based beverages, oral nutritional supplements, or dietary sources of prebiotics and probiotics. CONCLUSIONS: These are the first set of recommendations addressing the role of diet in the prevention and treatment of osteoporosis. More research is necessary to direct and support guidelines.

An experience- and preference-based EQ-5D-3L value set derived using 18 months of longitudinal data in patients who sustained a fracture: results from the ICUROS.

INTRODUCTION: EQ-5D-3L preference-based value sets are predominately based on hypothetical health states and derived in cross-sectional settings. Therefore, we derived an experience-based value set from a prospective observational study. METHODS: The International Costs and Utilities Related to Osteoporotic fractures Study (ICUROS) was a multinational study on fragility fractures, prospectively collecting EQ-5D-3L and Time trade-off (TTO) within two weeks after fracture (including pre-fracture recall), and at 4, 12, and 18 months thereafter. We derived an EQ-5D-3L value set by regressing the TTO values on the ten impairment levels in the EQ-5D-3L. We explored the potential for response shift and whether preferences for domains vary systematically with prior impairment in that domain. Finally, we compared the value set to 25 other EQ-5D-3L preference-based value sets. RESULTS: TTO data were available for 12,954 EQ-5D-3L health states in 4683 patients. All coefficients in the value set had the expected sign, were statistically significant, and increased monotonically with severity of impairment. We found evidence for response shift in mobility, self-care, and usual activities. The value set had good agreement with the only other experience- and preference-based value set, but poor agreement with all hypothetical value sets. CONCLUSIONS: We present an experience- and preference-based value set with high face validity. The study indicates that response shift may be important to account for when deriving value sets. Furthermore, the study suggests that perspective (experienced versus hypothetical) is more important than country setting or demographics for valuation of EQ-5D-3L health states.

Pregnancy outcomes in women with primary Sjögren's syndrome: an analysis of data from the multicentre, prospective, GR2 study.

BACKGROUND: Adverse pregnancy outcomes in women with primary Sjögren's syndrome have only been evaluated retrospectively using heterogeneous methods and with contradictory results. We aimed to describe adverse pregnancy, delivery, and birth outcome risks in pregnant women with primary Sjögren's syndrome compared with those of a matched general population in France, and to identify factors predictive of disease flares or adverse pregnancy outcomes. METHODS: We conducted a multicentre, prospective, cohort study in France using the GR2 (Groupe de Recherche sur la Grossesse et les Maladies Rares) registry. Women from the GR2 study were eligible if they had conceived before March, 2021, had primary Sjögren's syndrome according to the American College of Rheumatology and European Alliance of Associations for Rheumatology (EULAR) 2016 classification criteria, and had an ongoing pregnancy at 12 weeks of gestation. In women who entered in the registry with pregnancies before 18 weeks of gestation, we sought to identify factors associated with primary Sjögren's syndrome flare (≥3-point increase in EULAR Sjögren's Syndrome Disease Activity Index [ESSDAI] score) or adverse pregnancy outcomes (fetal or neonatal death, placental insufficiency leading to a preterm delivery [<37 weeks of gestation], or small-for-gestational-age birthweight). A matched controlled study compared adverse pregnancy, delivery, and birth outcome rates between pregnant women with primary Sjögren's syndrome from the GR2 registry and matched controls from the general population included in the last French perinatal survey (Enquête Nationale Périnatale 2016). FINDINGS: 1944 pregnancies were identified in the GR2 cohort, of which 106 pregnancies in 96 women with primary Sjögren's syndrome were included in this analysis. The median age at pregnancy onset was 33 years (IQR 31-36). 87 (83%) of 105 pregnancies (with ethnicity data) were in White women, 18 (17%) were in Black women; 92 (90%) of 102 had previous systemic activity (ESSDAI score of ≥1; data missing in four pregnancies), and 48 (45%) of 106 had systemic activity at inclusion. Of 93 pregnancies included at week 18 of gestation or earlier, primary Sjögren's syndrome flares occurred in 12 (13%). No baseline parameters were associated with primary Sjögren's syndrome flare. Four twin pregnancies and one medical termination were excluded from the adverse pregnancy outcome analysis; of the remaining 88, adverse pregnancy outcomes occurred in six (7%). Among pregnancies in women with data for antiphospholipid antibodies (n=55), antiphospholipid antibody positivity was more frequent among pregnancies with adverse outcomes (two [50%] of four pregnancies) compared with those without adverse outcomes (two [4%] of 51 pregnancies; p=0·023). Anti-RNP antibody positivity was also more frequent among pregnancies with adverse outcomes than those without, although this was not statistically significant. In the matched controlled study, adverse pregnancy outcomes occurred in nine (9%) of 105 pregnancies in women with primary Sjögren's syndrome and 28 (7%) of the 420 matched control pregnancies; adverse pregnancy outcomes were not significantly associated with primary Sjögren's syndrome (odds ratio 1·31, 95% CI 0·53-2·98; p=0·52). INTERPRETATION: Pregnancies in women with primary Sjögren's syndrome had very good prognoses for mothers and fetuses, with no overall increase in adverse pregnancy outcome risk compared with the general population. Women with antiphospholipid antibodies or anti-RNP antibodies require close monitoring, because these factors might be associated with a higher risk of adverse pregnancy outcomes.

The Economic Burden of Severe Osteoporotic Fractures in the French Healthcare Database: The FRACTOS Study.

Osteoporosis carries a high medical, economic, and societal burden principally because of the risk of severe fractures. The objective of this cost-of-illness study was to describe health resource utilization and associated costs in all patients aged ≥50 years hospitalized for a severe osteoporotic fracture over a 6-year period (2009 to 2014) in France. Data were extracted from the French national healthcare database (SNDS) on all health care resource utilization between the index date (date of hospitalization for first fracture during the enrollment period) and study end (December 31, 2016) or until the patient died. Costing was restricted to direct costs and determined from the payer perspective. Variables related to costs were identified through multivariate logistic regression analysis. A total of 356,895 patients were included (median follow-up 39.1 months). In the year after the index fracture, 36,622 patients (10.5%) were rehospitalized for a fracture-related reason. Only 18,474 (5.3%) underwent bone densitometry and 58,220 (16.7%) received a specific treatment. The total annual per capita osteoporosis-related cost in the year after the index severe osteoporotic fracture was €18,040 (from €8598 for multiple ribs to €21,085 for hip fracture) of which €17,905 was incurred by fracture-related costs. The cost incurred by management of osteoporosis was €135. Over years 2 to 5, the mean annual per capita costs of fracture treatment (€806, mostly attributable to the treatment of refractures) continued to dominate those of osteoporosis management (€99). Total annual cost of care was €1260 million (year 2014). Variables associated with higher cost were older age, male sex, site of fracture, a history of prior osteoporotic fracture, and the number of refracture events. The 5-year cost of severe osteoporotic fractures to the French health care system is high and mostly attributable to the treatment of refractures. Improved fracture prevention measures in patients with osteoporosis is crucial to reduce the economic burden of the disease. © 2022 The Authors.

Role of vitamin D supplementation in the management of musculoskeletal diseases: update from an European Society of Clinical and Economical Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO) working group.

Vitamin D is a key component for optimal growth and for calcium-phosphate homeostasis. Skin photosynthesis is the main source of vitamin D. Limited sun exposure and insufficient dietary vitamin D supply justify vitamin D supplementation in certain age groups. In older adults, recommended doses for vitamin D supplementation vary between 200 and 2000 IU/day, to achieve a goal of circulating 25-hydroxyvitamin D (calcifediol) of at least 50 nmol/L. The target level depends on the population being supplemented, the assessed system, and the outcome. Several recent large randomized trials with oral vitamin D regimens varying between 2000 and 100,000 IU/month and mostly conducted in vitamin D-replete and healthy individuals have failed to detect any efficacy of these approaches for the prevention of fracture and falls. Considering the well-recognized major musculoskeletal disorders associated with severe vitamin D deficiency and taking into account a possible biphasic effects of vitamin D on fracture and fall risks, an European Society for Clinical and Economic Aspects of Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (ESCEO) working group convened, carefully reviewed, and analyzed the meta-analyses of randomized controlled trials on the effects of vitamin D on fracture risk, falls or osteoarthritis, and came to the conclusion that 1000 IU daily should be recommended in patients at increased risk of vitamin D deficiency. The group also addressed the identification of patients possibly benefitting from a vitamin D loading dose to achieve early 25-hydroxyvitamin D therapeutic level or from calcifediol administration.

Protective Effect on Bone of Nacre Supplementation in Ovariectomized Rats.

Nacre has emerged as a beneficial natural product for bone cells and tissues, but its effect was only studied by gavage in the ovariectomized mouse model. We sought to assess the antiosteoporotic effect of nacre through a nutritional supplementation in the ovariectomized rat model. Sixteen-week-old female Wistar rats were either Sham-operated or bilateral ovariectomized (OVX) and then fed with standard diet (Sham and OVX groups) or standard diet supplemented with either 0.25% CaCO3 or nacre (OVX CaCO3 and OVX Nacre group, respectively) for 28 days (n = 10/group). The bone microarchitecture was assessed at appendicular and axial bones by micro-computed tomography (µCT). Histomorphometric analysis was performed to determine cellular and dynamic bone parameters. Bone metabolism was also evaluated by biochemical markers and gene expression levels. Nacre-based diet prevented the OVX-induced bone loss better than that of the CaCO3 supplement, given the significant changes in trabecular bone volume fraction (BV/TV) both at the femoral distal metaphysis (difference, 35%; p = 0.004) and at the second lumbar spine (difference, 11%; p = 0.01). Trabecular osteoclast surfaces (Oc.S/BS) were also 1.5-fold lower at the tibial proximal metaphysis in OVX Nacre group compared with OVX CaCO3 group (p = 0.02). By principal component analysis (PCA), OVX Nacre group formed a cluster away from OVX group and with a trend closest to Sham group. These data were consistent with biological measurements demonstrating a positive profile related to nacre supplementation, which blunted an increase in serum CTX level and enhanced serum P1NP secretion 14 days post-OVX compared with CaCO3 supplementation. Bmp2 mRNA expression in OVX Nacre group was +1.76-fold (p = 0.004) and +1.30-fold (p = 0.20) compared with OVX and OVX CaCO3 groups, respectively. We conclude that supplementation with nacre could effectively limit bone loss induced by estrogen deficiency just after OVX in rats by modulating the negative imbalance of bone turnover. © 2022 The Authors.

The effects of combined amplitude and high-frequency vibration on physically inactive osteopenic postmenopausal women.

Purpose: To evaluate whole-body vibration (WBV) osteogenic potential in physically inactive postmenopausal women using high-frequency and combined amplitude stimuli. Methods: Two-hundred fifty-five physically inactive postmenopausal women (55-75 years) with 10-year major osteoporotic fracture risk (3%-35%) participated in this 18-month study. For the first 12 months, the vibration group experienced progressive 20-min WBV sessions (up to 3 sessions/week) with rest periods (30-60 s) between exercises. Frequencies (30-50 Hz), with low (0.2-0.4 mm) and high (0.6-0.8 mm) amplitude stimuli were delivered via PowerPlate Pro5 platforms producing accelerations of (0.75-7.04 g). The last 6 months for the treatment group were a follow-up period similar to control. Serum bone remodelling markers [C-terminal crosslinked telopeptide of type-1 collagen (CTX), procollagen type-1 N-terminal propeptide (P1NP), bone alkaline phosphatase (BAP) and sclerostin] were measured at fasting. CTX and P1NP were determined by automated chemiluminescence immunoassay, bone alkaline phosphatase (BAP) by automated spectrophotometric immunoassay, and sclerostin by an enzyme-immunoassay. Bone mineral density (BMD) of the whole-body, proximal femur and lumbar vertebrae was measured by dual-energy X-ray absorptiometry (DXA). Bone microarchitecture of the distal non-dominant radius and tibia was measured by high-resolution peripheral quantitative computed tomography (HR-pQCT). Results: Femoral neck (p = 0.520) and spine BMD (p = 0.444) failed to improve after 12 months of WBV. Bone macro and microstructural parameters were not impacted by WBV, as well as estimated failure load at the distal radius (p = 0.354) and tibia (p = 0.813). As expected, most DXA and HR-pQCT parameters displayed age-related degradation in this postmenopausal population. BAP and CTX increased over time in both groups, with CTX more marginally elevated in the vibration group when comparing baseline changes to month-12 (480.80 pmol/L; p = 0.039) and month-18 (492.78 pmol/L; p = 0.075). However, no differences were found when comparing group concentrations only at month-12 (506.35 pmol/L; p = 0.415) and month-18 (518.33 pmol/L; p = 0.480), indicating differences below the threshold of clinical significance. Overall, HR-pQCT, DXA bone parameters and bone turnover markers remained unaffected. Conclusion: Combined amplitude and high-frequency training for one year had no ameliorating effect on DXA and HR-pQCT bone parameters in physically inactive postmenopausal women. Serum analysis did not display any significant improvement in formation and resorption markers and also failed to alter sclerostin concentrations between groups.
