RESUMEN
BACKGROUND AND PURPOSE: Low socio-economic status of individuals has been reported to be associated with a higher incidence of stroke and influence the diagnosis after revascularization. However, whether it is associated with poorer acute stroke management is less clear. To determine whether social deprivation was associated with a poorer access to reperfusion therapy, either intravenous thrombolysis (IVT) and/or endovascular thrombectomy (EVT) in a population-based cohort. METHODS: Over a 14-month period, all consecutive adult patients admitted to any emergency department or a comprehensive or primary stroke center (CSC/PSC) of the Rhône county with a confirmed ischemic stroke were included. The socioeconomic status of each patient was measured using the European Deprivation Index (EDI). The association between EDI and access to reperfusion therapy was assessed in univariate and multivariate logistic regression analyses. RESULTS: Among the 1226 consecutive IS patients, 316 (25%) were admitted directly in a PSC or CSC, 241 (19.7%) received a reperfusion therapy; 155 IVT alone, 20 EVT alone, and 66 both therapies. Median age was 79 years, 1030 patients had an EDI level of 1 to 4, and 196 an EDI of 5 (the most deprived group). The most deprived patients (EDI level 5) did not have a poorer access to reperfusion therapy compared to all other patients in univariate (OR 1.22, 95%CI [0.85; 1.77]) nor in multivariate analyses (adjOR 0.97, 95%CI [0.57; 1.66]). CONCLUSIONS: We did not find any significant association between socioeconomic deprivation and access to reperfusion therapy. This suggests that the implementation of EVT was not associated with increased access inequities.

BACKGROUND: We aimed to describe and discuss the algorithms used to identify chronic inflammatory rheumatisms and psoriasis in medico-administrative databases. METHODS: We performed a literature review on the Medline database of articles published up to 31 January 2018. Our inclusion criteria were: original articles using medico-administrative databases in accordance with the International Classification of Diseases, version 10 (ICD-10) and concerning rheumatoid arthritis (RA) or ankylosing spondylitis (AS) or psoriatic arthritis (PsoA) or Psoriasis (Pso). Our exclusion criteria were: letters to the editor, commentaries on published articles, studies using codes other than those of the ICD or a previous version. RESULTS: Out of the 590 articles identified, 37 studies were included. Concerning RA (n=10), all studies used the M05 code, associated with the M06 code in six studies. The remaining four studies specifically targeted codes M06.0, M06.2, M06.3, M06.8, M06.9, and two of them also used code M12.3. For AS (n=8), 7 studies used the M45 code, while only one study used M45.9, M46.1 or M46.8. For Pso (n=17), all studies used the L40 code and/or at least two dispensations of vitamin D. Concerning PsoA (n=13), all studies used the same codes: M07.0, M07.1, M07.2, M07.3. CONCLUSION: We recommend using codes M05 and M06 rather than M06.1 and M06.4 for RA, M45 for AS, the algorithm L40 and/or two dispensations of topical vitamin D for psoriasis, and codes M070 to M073 to identify PsoA patients in medico-administrative databases.

BACKGROUND: Optimizing access to recanalization therapies in acute ischemic stroke patients is crucial. Our aim was to measure the short and long term effectiveness, at the acute phase and 1 year after stroke, of four sets of actions implemented in the Rhône County. METHODS: The four multilevel actions were 1) increase in stroke units bed capacity and development of endovascular therapy; 2) improvement in knowledge and skills of healthcare providers involved in acute stroke management using a bottom-up approach; 3) development and implementation of new organizations (transportation routes, pre-notification, coordination by the emergency call center physician dispatcher); and 4) launch of regional public awareness campaigns in addition to national campaigns. A before-and-after study was conducted with two identical population-based cohort studies in 2006-7 and 2015-16 in all adult ischemic stroke patients admitted to any emergency department or stroke unit of the Rhône County. The primary outcome criterion was in-hospital management times, and the main secondary outcome criteria were access to reperfusion therapy (either intravenous thrombolysis or endovascular treatment) and pre-hospital management times in the short term, and 12-month prognosis measured by the modified Rankin Scale (mRS) in the long term. RESULTS: Between 2015-16 and 2006-7 periods ischemic stroke patients increased from 696 to 717, access to reperfusion therapy increased from 9 to 23% (p < 0.0001), calls to emergency call-center from 40 to 68% (p < 0.0001), first admission in stroke unit from 8 to 30% (p < 0.0001), and MRI within 24 h from 18 to 42% (p < 0.0001). Onset-to-reperfusion time significantly decreased from 3h16mn [2 h54-4 h05] to 2h35mn [2 h05-3 h19] (p < 0.0001), mainly related to a decrease in delay from admission to imaging. A significant decrease of disability was observed, as patients with mild disability (mRS [0-2]) at 12 months increased from 48 to 61% (p < 0.0001). Pre-hospital times, however, did not change significantly. CONCLUSIONS: We observed significant improvement in access to reperfusion therapy, mainly through a strong decrease of in-hospital management times, and in 12-month disability after the implementation of four sets of actions between 2006 and 2016 in the Rhône County. Reducing pre-hospital times remains a challenge.

BACKGROUND AND PURPOSE: Large societal costs of stroke should not be ignored. We aimed to estimate patients' productivity losses and informal care costs during the first year after ischemic stroke. METHODS: A cross-sectional survey was performed within the STROKE69 regional population-based cohort study. At 1 year post-stroke, each patient and the corresponding main informal caregiver received questionnaires followed by a telephone interview if necessary. Time losses were valued using the human capital approach and proxy good method for patients with and without a professional activity, respectively. RESULTS: Among the 222 patients with ischemic stroke (58% men; mean age 68 years; and 86% with a modified Rankin Scale (mRS) score of <3 at 3 months), 54%, 32%, and 25% received informal, formal, and both cares, respectively. Among the 108 main informal caregivers, 63% were women, 74% lived with the patient, and 57% were retired or unemployed. The mean cost of productivity losses was estimated at 7589 ± 12 305 per patient in the first post-stroke year with 5.4%, 71.2%, and 23.4% of these being attributed to presenteeism, absenteeism, and leisure time, respectively. Informal care was given at an average of 25 h/week. The annual mean estimated total cost of informal care was 10 635 per caregiver. CONCLUSIONS: Informal care and productivity losses of patients with ischemic stroke during the first post-stroke year represent a significant economic burden for society comparable to direct costs. These costs should be included in economic evaluations with the adoption of a societal perspective to avoid underestimating the societal stroke economic burden.

BACKGROUND: Acute telestroke is the use of telemedicine to improve acute stroke care. It has demonstrated to be a safe and effective medical practice. Since 2011, acute telestroke has been promoted by the Ministry of Health in France, and in 2018 many regions were in the process or completion of implementing telestroke. The objective of this study was to describe acute telestroke implementation in France. METHODS: A systematic review was conducted using PubMed and ScienceDirect databases. Articles and abstracts in English and French, published between January 1st, 2000 to April 30th, 2018 were used. Studies conducted in France and that had presented an outcome evaluation of a regional acute telestroke activity were included. No meta-analysis was conducted. RESULTS: A total of 24 studies (14 in French, 10 in English) were included, with 13 published articles (7 indexed on PubMed) and 11 abstracts. Among the 13 published articles, there were seven observational retrospective studies, one quasi-experimental before-after study, one experimental randomised controlled trial, and four medico-economic studies. All telestroke network models of care were drip-and-ship with hub and spoke organisation. The case-control studies did not show a difference with or without telemedicine. The territorial thrombolysis rate was measured in two regions, with an increase in Franche-Comté from 0.2% (2004) to 9.9% (2015), and a relative increase of 76% in Nord-Pas-de-Calais between 2009-2010 and 2012. CONCLUSION: Implementation of acute telestroke in France had a positive clinical and public health impact but the evaluation remained limited and needs to be supported.

Osteoporosis (OP) is a major public health concern, but still OP care does not meet guidelines. Interventions have been developed to improve appropriate OP management. The objective of the present study was to systematically review the current literature to ascertain the efficacy of interventions to improve OP care and characterize interventions taking into account elements related to their potential cost and feasibility. Studies published from 2003 to 2018 were retrieved from PubMed/MEDLINE, Science Direct, Web of Science, Cochrane, and Wiley Online Library databases. Screening of references and quality assessment were independently performed by two reviewers. We classified interventions into three types according to the target of the intervention: health system (structural interventions), healthcare professional (HCP), and patient. Meta-analysis was performed by type of intervention and their effect on two outcomes: prescription of BMD measurement and prescription of OP therapy. A total of 4268 records were screened; 32 studies were included in the qualitative analysis and 29 studies in the quantitative analysis. Structural interventions strongly and significantly improved prescription of BMD measurement (OR = 9.99, 95% CI 2.05; 48.59) and treatment prescription (OR = 3.82, 95% CI 2.16; 6.75). The impact of HCP-centered interventions on BMD measurement prescription did not reach statistical significance (OR = 2.19, 95% CI 0.84; 5.73) but significantly improved treatment prescription (OR = 3.82, 95% CI 2.16; 6.75). Interventions involving patients significantly improved the prescription of BMD measurement (OR = 2.16, 95% CI 1.62; 2.89) and treatment prescription (OR = 1.70, 95% CI 1.35; 2.14). Interventions to improve OP management had a significant positive impact on prescription of BMD measurement but a more limited impact on treatment prescription.

BACKGROUND: The establishment of a common pragmatic terminology represents the first step in structuring patient engagement initiatives in healthcare facilities. However, none is currently available in French. As part of the deployment of patient engagement within a French University Hospital Center, we propose a terminology of patient engagement. METHODS: We conducted a scoping review of the international literature that aimed at identifying the main conceptual and terminological frameworks for the engagement of patients, users and citizens in the healthcare system until 2019 in the PubMed and Cairn.info databases for English and French language articles. Additionally, we identified concepts and practices in the leading organizations of countries where this approach was implemented (United States, Canada and especially the province of Quebec, United Kingdom) and completed this approach by close exchanges and reflections with the team that developed the Montreal model. RESULTS: In total, 75 references and Internet resources were consulted. Patient, interaction, patient experience, experiential knowledge, patient engagement, patient partner and its variations as a resource patient, peer-supporter, trainer, researcher and coach have been defined. CONCLUSION: This terminology of patient engagement proposes an initial stabilization of the vocabulary, using a pragmatic approach. This contribution is a first step aiming at promoting the development of a new model of care and more broadly of healthcare system management, involving scientific and experiential knowledge.

OBJECTIVES: To determine the cost-effectiveness of stent retriever thrombectomy (SRT) added to standard of care (SOC) in large vessel occlusion (LVO) strokes, adopting the French societal perspective given the lack of published studies with such perspective. METHODS: We developed an hybrid model (decision tree until one year post-stroke followed by a Markov model from one year onward). The time horizon was 20 years. We calculated transition probabilities across the modified Rankin Scale (mRS) based on a published meta-analysis. The main outcome measure was quality adjusted life-years (QALYs) gained. Resources and input costs were derived from a literature search. We calculated the incremental cost-effectiveness ratio (ICER) expressed as cost/QALY. We used 1-way deterministic and probabilistic sensitivity analysis (PSA) to evaluate the model uncertainty. RESULTS: In the base-case, adding SRT to SOC resulted in increased effectiveness of 0.73 QALY while total costs were reduced by 3,874 (ICER of -5,400/QALY). In the scenario analysis adopting the French healthcare system perspective, the ICER was 4,901/QALY. Parameters the most influential were the relative risks of SRT over SOC for 90-days mortality and for 90-days mRS 0-2, and the time horizon. PSA showed the 95% confidence interval of the ICER was -21,324 to 4,591/QALY, with SRT having 85.5% chance to be dominant and 100% to be cost-effective at a threshold of 50,000/QALY. CONCLUSION: SRT was dominant from a French societal perspective, from 9 years post-stroke onwards. Cost-effectiveness of SRT added to SOC becomes undisputable with evidences from payer and societal viewpoints.

BACKGROUND AND PURPOSE: Motoric cognitive risk syndrome (MCR), which is the juncture of subjective cognitive complaint and slow gait speed, is a pre-dementia stage. The aims of the study are (i) to compare characteristics between individuals who have MCR defined using slow walking speed and/or increased five-times-sit-to-stand (FTSS) time as its motor component(s); and (ii) to characterize the association of MCR and its various motor components with incident dementia including Alzheimer disease and non-Alzheimer dementia in the participants of the Epidémiologie de l'Ostéoporose (EPIDOS) study. METHODS: This prospective and observational cohort study selected 651 participants recruited from the EPIDOS study in Toulouse (France). MCR was defined as the association of subjective cognitive complaint and slow gait speed and/or increased FTSS time in participants without either dementia and mobility disabilities at baseline. Individuals with dementia were prospectively diagnosed during the physical and neuropsychological assessments included in the 7-year follow-up. RESULTS: The prevalence of MCR was around 7% when using an exclusive motor criterion, either slow gait speed or increased FTSS time, and was 20.9% when MCR subgroups were pooled. MCR was positively associated with incident dementia regardless of its type, and with Alzheimer disease in the slow gait speed MCR subgroup [odds ratio (OR) > 2.18 with P ≤ 0.037] but not with non-Alzheimer dementia. No significant association between incident dementia and MCR defined using increased FTSS time was shown. CONCLUSIONS: Our findings confirm that MCR is associated with incident dementia and that slow gait speed is the appropriate motor criterion for detecting dementia risk.

BACKGROUND AND PURPOSE: Cognitive impairment, slow walking speed and motoric cognitive risk syndrome (MCR) have separately been associated with an increased risk for mortality in the short term. The aim of the study was to examine the association of MCR and its components [i.e. subjective cognitive complaint (SCC) and slow walking speed] with short-, medium- and long-term mortality in older community-dwellers. METHODS: In all, 3778 participants from the Epidémiologie de l'Ostéoporose (EPIDOS) study were selected. MCR was defined as the combination of slow walking speed and SCC in participants without major neurocognitive disorders. Deaths were prospectively recorded using mail, phone calls, questionnaires and/or the French national death registry at 5, 10, 15 and 19 (end of follow-up period) years. RESULTS: Over the follow-up of 19 years, 80.5% (n = 3043) participants died. Slow walking speed and MCR were associated with mortality [hazard ratio (HR) 1.20 with P = 0.004 for slow walking speed and HR = 1.26 with P = 0.002 for MCR at 10 years; HR = 1.27 with P ≤ 0.001 for slow walking speed and HR = 1.22 with P = 0.001 for MCR at 15 years; HR = 1.41 with P ≤ 0.001 at 19 years for slow walking speed and MCR]. There was no association between SCC and mortality. Kaplan-Meier distributions of mortality showed that participants with MCR and slow walking speed died earlier compared to healthy participants and those with SCC (P < 0.001). CONCLUSIONS: Slow walking speed and MCR were associated with an increased risk for mortality at the medium and long term, whereas no association was found with SCC.

We conducted a qualitative study with French men and women in order to provide insight into individuals' experiences, behaviors, and perceptions about osteoporosis (OP) and OP care. The data showed that both sexes, but especially men, were unfamiliar with OP, did not always feel concerned, and mistrusted pharmacological treatments. INTRODUCTION: To engage actively in osteoporosis (OP) prevention, people need to have basic knowledge about the disease. The aim of this qualitative study was to explore knowledge and representations of OP care and prevention among both men and women. METHODS: Focus groups were conducted in the Rhône-Alpes Region, France, with women aged 50-85 years and men aged 60-85 years, with or without a history of fragility fracture and/or an OP diagnosis (respectively referred to as "aware" or "unaware"). A total of 45 women (23 "aware" and 22 "unaware" in 5 and 4 focus groups, respectively) and 53 men (19 "aware" and 34 "unaware" in 3 and 4 focus groups, respectively) were included. A thematic analysis of transcripts was performed to explore knowledge and representations about OP, risk factors, prevention, and treatment. RESULTS: The data showed that both sexes, but especially men, had limited knowledge of OP and considered it as a natural aging process not related to fragility fractures. They generally did not feel concerned by OP and no important difference was observed between "aware" and "unaware" patients. Women expressed their fear of the disease, associated with aging and the end of life, while men considered it to be a women's disease only. Both sexes were aware of OP risk factors, but were suspicious towards treatments because of the associated side effects. CONCLUSION: Understanding people's representation of OP might help to provide patients with relevant information in order to optimize their preventive behavior and decrease the burden of the disease.

BACKGROUND AND PURPOSE: Endovascular thrombectomy has become the reference therapy for patients with large vessel occlusion (LVO). However, no meta-analysis including the THRACE Trial has yet been reported. Thus, the present review assessed the outcomes of stent retriever thrombectomy added to medical care compared with medical care alone in LVO patients. MATERIALS AND METHODS: A systematic review was conducted of all randomized controlled trials (RCTs) examining stent retrievers added to medical care vs medical care alone in the MEDLINE, Embase and Web of Science databases. Meta-analyses of 90-day functional outcomes and mortality, and the occurrence of symptomatic intracranial hemorrhage (sICH), with thrombectomy plus medical care vs medical care alone were performed. RESULTS: Six multicenter RCTs involving 1673 patients were included. Successful recanalization (modified thrombolysis in cerebral ischemia grades 2b-3) was seen in 71% of patients (95% CI: 62-79%) after thrombectomy. These patients also had significantly higher rates of 90-day functional independence (mRS scores 0-2) compared with those receiving medical care only (OR: 2.14, 95% CI: 1.72-2.67; P<0.00001), as well as excellent outcomes (mRS scores 0-1, OR: 2.05, 95% CI: 1.58-2.67; P<0.00001). Also, the rate of functional independence was higher (OR: 2.39, 95% CI: 1.88-3.04; P<0.00001) in the subgroup analysis without the THRACE Trial. The effect of endovascular therapy on 90-day mortality was inconclusive (OR: 0.82, 95% CI: 0.62-1.07; P=0.15), and there was no increased occurrence of sICH (OR: 1.11, 95% CI: 0.66-1.88; P=0.70). CONCLUSION: Stent retriever thrombectomy added to medical care improved 90-day functional outcomes compared with medical care alone with no impact on mortality and risk of sICH in LVO patients.

BACKGROUND: Vitamin D affects physical performance in older adults. Its effects on muscles, notably on muscle strength, remain unclear. The objective of this cross-sectional study was to determine whether hypovitaminosis D is associated with triceps brachii muscle fatigability in community-dwelling older women. METHODS: A randomized subset of 744 women aged ≥75years from the EPIDOS cohort was categorized into two groups according to triceps brachii muscle fatigability, defined as loss of strength >5% between two consecutive maximal isometric voluntary contractions. Hypovitaminosis D was defined using consensual threshold values (i.e., serum 25-hydroxyvitamin D concentration [25OHD] ≤10â¯ng/mL, ≤20â¯ng/mL, and ≤30â¯ng/mL). Age, body mass index, comorbidities, use psychoactive drugs, physical activity, first triceps strength measure, hyperparathyroidism, serum concentrations of calcium, albumin and creatinine, season and study centers were used as potential confounders. RESULTS: The prevalence of hypovitaminosis Dâ¯≤â¯30â¯ng/mL was greater among women with muscle fatigability compared with the others (Pâ¯=â¯.009). There was no between-group difference using the other definitions of hypovitaminosis D. The serum 25OHD concentration was inversely associated with the between-test change in triceps strength (adjusted ßâ¯=â¯-0.09â¯N, Pâ¯=â¯.04). Hypovitaminosis Dâ¯≤â¯30â¯ng/mL was positively associated with triceps fatigability (adjusted ORâ¯=â¯3.15, Pâ¯=â¯.02). CONCLUSIONS: Vitamin D concentration was inversely associated with the ability to maintain strength over time in this cohort of community-dwelling older women. This is a relevant new orientation of research toward understanding the involvement of vitamin D in muscle function.

BACKGROUND: The World Health Organization refers to stroke, the second most frequent cause of death in the world, in terms of pandemic. Present treatments are only effective within precise time windows. Only 10% of thrombolysis patients are eligible. Late assessment of the patient resulting from admission and lack of knowledge of the symptoms is the main explanation of lack of eligibility. METHODS: The aim is the measurement of the time of access to treatment facilities for stroke victims, using ambulances (firemen ambulances or EMS ambulances) and private car. The method proposed analyses the potential geographic accessibility of stroke care infrastructure in different scenarios. The study allows better considering of the issues inherent to an area: difficult weather conditions, traffic congestion and failure to respect the distance limits of emergency transport. RESULTS: Depending on the scenario, access times vary considerably within the same commune. For example, between the first and the second scenario for cities in the north of Rhône county, there is a 10 min difference to the nearest Primary Stroke Center (PSC). For the first scenario, 90% of the population is 20 min away of the PSC and 96% for the second scenario. Likewise, depending on the modal vector (fire brigade or emergency medical service), overall accessibility from the emergency call to admission to a Comprehensive Stroke Center (CSC) can vary by as much as 15 min. CONCLUSIONS: The setting up of the various scenarios and modal comparison based on the calculation of overall accessibility makes this a new method for calculating potential access to care facilities. It is important to take into account the specific pathological features and the availability of care facilities for modelling. This method is innovative and recommendable for measuring accessibility in the field of health care. This study makes possible to highlight the patients' extension of care delays. Thus, this can impact the improvement of patient care and rethink the healthcare organization. Stroke is addressed here but it is applicable to other pathologies.

BACKGROUND: Osteoporotic hip fractures (OHF) are associated with significant morbidity and mortality. The French medico-administrative database (SNIIRAM) offers an interesting opportunity to improve the management of OHF. However, the validity of studies conducted with this database relies heavily on the quality of the algorithm used to detect OHF. The aim of the REDSIAM network is to facilitate the use of the SNIIRAM database. The main objective of this study was to present and discuss several OHF-detection algorithms that could be used with this database. METHODS: A non-systematic literature search was performed. The Medline database was explored during the period January 2005-August 2016. Furthermore, a snowball search was then carried out from the articles included and field experts were contacted. The extraction was conducted using the chart developed by the REDSIAM network's "Methodology" task force. RESULTS: The ICD-10 codes used to detect OHF are mainly S72.0, S72.1, and S72.2. The performance of these algorithms is at best partially validated. Complementary use of medical and surgical procedure codes would affect their performance. Finally, few studies described how they dealt with fractures of non-osteoporotic origin, re-hospitalization, and potential contralateral fracture cases. CONCLUSIONS: Authors in the literature encourage the use of ICD-10 codes S72.0 to S72.2 to develop algorithms for OHF detection. These are the codes most frequently used for OHF in France. Depending on the study objectives, other ICD10 codes and medical and surgical procedures could be usefully discussed for inclusion in the algorithm. Detection and management of duplicates and non-osteoporotic fractures should be considered in the process. Finally, when a study is based on such an algorithm, all these points should be precisely described in the publication.

We conducted a multicenter, randomized controlled trial to evaluate the impact of a population-based patient-centered post-fracture care program with a dedicated case manager, PREVention of OSTeoporosis (PREVOST), on appropriate post-fracture osteoporosis management. We showed that, compared to usual care, BMD investigation post-fracture was significantly improved (+20%) by our intervention program. INTRODUCTION: Our study aims to evaluate the impact of a population-based patient-centered post-fracture care program, PREVOST, on appropriate post-fracture care. METHODS: Multicenter, randomized controlled trial enrolling 436 women aged 50 to 85 years and attending a French hospital, for a low-energy fracture of the wrist or humerus. Randomization was stratified by age, hospital department, and site of fracture. The intervention was performed by a trained case manager who interacted only with the patients, with repeated oral and written information about fragility fractures and osteoporosis management, and prompting them to visit their primary care physicians. Control group received usual care. The primary outcome was the initiation of an appropriate post-fracture care defined by Bone Mineral Density (BMD) and/or anti-osteoporotic treatment prescription at 6 months. RESULTS: At 6 months, 53% of women in intervention group initiated a post-fracture care versus 33% for usual care (adjOR 2.35, 95%CI [1.58-3.50], p < 0.001). Post-fracture care was more frequent after wrist than humerus fracture (adjOR 1.93, 95%CI [1.14-3.30], p = 0.015) and decreased with age (adjOR for 10 years increase 0.76, 95%CI [0.61-0.96], p = 0.02). The intervention resulted in BMD prescription in 50% of patients (adjOR 2.10, 95%CI [1.41-3.11], p < 0.001) and in BMD performance in 41% of patients (adjOR 2.12, 95%CI [1.40-3.20], p < 0.001) versus 33 and 25% for usual care, respectively. Having performed a BMD increased treatment prescription; however, only 46% of women with a low BMD requiring a treatment according to the French guidelines received a prescription. CONCLUSION: A patient-centered care program with a dedicated case manager can significantly improve post-fracture BMD investigation.

Assessing morphological, perfusion and metabolic brain changes preceding or associated with neuropsychiatric symptoms (NPSs) will help in the understanding of pathophysiological underlying processes in Alzheimer's disease (AD). This review aimed to highlight the main findings on significant associations between neuroimaging and NPSs, the pathophysiology to elucidate possible underlying mechanisms, and methodological issues to aid future research. Research papers published from January 1990 to October 2015 were identified in the databases PsycInfo, Embase, PubMed and Medline, using key words related to NPSs and imaging techniques. In addition to a semi-systematic search in the databases, we also performed hand searches based on reported citations identified to be of interest. Delusions, apathy and depression symptoms were particularly associated with brain changes in AD. The majority of studies disclosed an association between frontal lobe structural and/or metabolic changes and NPSs, implicating, interestingly, for all 12 NPSs studied, the anterior cingulate cortex although temporal, subcortical and parietal regions, and insula were also involved. Given the high degree of connectivity of these brain areas, frontal change correlates of NPSs may help in the understanding of neural network participation. This review also highlights crucial methodological issues that may reduce the heterogeneity of results to enable progress on the pathophysiological mechanisms and aid research on NPS treatments in AD. Based on a broad review of the current literature, a global brain pattern to support the huge heterogeneity of neuroimaging correlates of NPSs in AD and methodological strategies are suggested to help direct future research.

OBJECTIVE: Concerning death-rates were reported following prostate biopsy but the lack of contexts in which event occurred makes it difficult to take any position. Therefore, we aimed to determine the 120-day post-biopsy mortality rate. MATERIAL AND METHODS: Between 2000 and 2011, 8804 men underwent prostate biopsy in the hospice civils de Lyon. We studied retrospectively, the mortality rate after each of the 11,816 procedures. Biopsies imputability was assessed by examining all medical records. Dates of death were extracted from our local patient management database, which is updated trimestrially with death notifications from the French National Institute for Statistics and Economic Studies. RESULTS: In our study 42 deaths occurred within 120days after 11,816 prostate biopsies (0.36%). Of the 42 records: 9 were lost to follow-up, 3 had no identifiable cause of death, 28 had an intercurrent event ruling out prostate biopsy as a cause of death. Only 2 deaths could be linked to biopsy. CONCLUSIONS: We reported at most 2 deaths possibly related to prostate biopsy over 11,816 procedures (0.02%). We confirmed the fact that prostate biopsies can be lethal but this rare outcome should not be considered as an argument against prostate screening given the circumstances in which it occurs. LEVEL OF EVIDENCE: 5.

UNLABELLED: We performed a cost-effectiveness analysis of four vitamin D supplementation strategies for primary prevention of hip fracture among the elderly population and found that the most cost-effective strategy was screening for vitamin D insufficiency followed by adequate treatment to attain a minimum 25(OH) serum level. INTRODUCTION: Vitamin D supplementation has a demonstrated ability to reduce the incidence of hip fractures. The efficiency of lifetime supplementation has not yet been assessed in the population over 65 years without previous hip fracture. The objective was to analyze the efficiency of various vitamin D supplementation strategies for that population. METHODS: A Markov micro-simulation model was built with data extracted from published studies and from the French reimbursement schedule. Four vitamin D supplementation strategies were evaluated on our study population: (1) no treatment, (2) supplementation without any serum level check; (3) supplementation with a serum level check 3 months after initiation and subsequent treatment adaptation; (4) population screening for vitamin D insufficiency followed by treatment based on the vitamin D serum level. RESULTS: "Treat, then check" and "screen and treat" were two cost-effective strategies and dominated "treat without check" with incremental cost-effectiveness ratios of 5,219/quality-adjusted life-years (QALY) and 9,104/QALY, respectively. The acceptability curves showed that over 6,000/QALY, the "screen and treat" strategy had the greatest probability of being cost-effective, and the "no treatment" strategy would never be cost-effective if society were willing to spend over 8,000/QALY. The sensitivity analysis showed that among all parameters varying within realistic ranges, the cost of vitamin D treatment had the greatest effect and yet remained below the WHO cost-effectiveness thresholds. CONCLUSIONS: Population screening for vitamin D insufficiency followed by treatment based on the vitamin D serum level is the most cost-effective strategy for preventing hip fracture occurrence in the population over 65 years old.

OBJECTIVE: High arterial pulse pressure is a predictor of cardiovascular morbimortality. Mineral metabolism has been associated with blood pressure regulation. Our objective was to determine which variable among serum calcium, parathyroid hormone and 25-hydroxyvitamin D concentrations, was associated with pulse pressure among older adults. DESIGN: Cross-sectional study corresponding to the baseline assessment of the EPIDOS study. SETTING: Five French cities including Amiens, Lyon, Montpellier, Paris and Toulouse. PARTICIPANTS: Randomized sample of 610 community-dwelling older women (mean age 80.2±3.5years) using no antihypertensive drugs. MEASUREMENTS: Serum calcium, parathyroid hormone and 25-hydroxyvitamin D concentrations; supine pulse pressure after 15 minutes of rest (hypertension defined as pulse pressure >50mmHg). Age, body mass index, the number of morbidities and of drugs daily taken, diabetes mellitus, dysthyroidy, the use of estrogenic drugs, smoking, alcohol consumption, practice of a regular physical activity, creatinine clearance, and the effects of season and study centers were used as potential confounders. RESULTS: Hypertensive participants (n=539) had higher calcium concentrations than normotensive ones (94.33±4.12mg/L versus 93.28±3.36mg/L respectively, P=0.040). There were no between-group differences for serum parathyroid hormone and 25-hydroxyvitamin D concentrations. The multiple logistic regressions examining the serum calcium, parathyroid hormone and 25-hydroxyvitamin D concentrations as predictors of hypertension found an association only with calcium (adjusted odds ratio=1.19, P=0.015), but not with parathyroid hormone (adjusted OR=1.01, P=0.349) or 25-hydroxyvitamin D concentration (adjusted OR=0.99, P=0.971). CONCLUSION: Increased serum calcium concentration was independently and positively associated with high pulse pressure in our study, possibly due to increased arterial stiffness. Interventions aimed at normalizing calcaemia may be attractive to prevent hypertension and cardiovascular risk in older adults.
