A meta-analysis of previous falls and subsequent fracture risk in cohort studies.

The relationship between self-reported falls and fracture risk was estimated in an international meta-analysis of individual-level data from 46 prospective cohorts. Previous falls were associated with an increased fracture risk in women and men and should be considered as an additional risk factor in the FRAX® algorithm. INTRODUCTION: Previous falls are a well-documented risk factor for subsequent fracture but have not yet been incorporated into the FRAX algorithm. The aim of this study was to evaluate, in an international meta-analysis, the association between previous falls and subsequent fracture risk and its relation to sex, age, duration of follow-up, and bone mineral density (BMD). METHODS: The resource comprised 906,359 women and men (66.9% female) from 46 prospective cohorts. Previous falls were uniformly defined as any fall occurring during the previous year in 43 cohorts; the remaining three cohorts had a different question construct. The association between previous falls and fracture risk (any clinical fracture, osteoporotic fracture, major osteoporotic fracture, and hip fracture) was examined using an extension of the Poisson regression model in each cohort and each sex, followed by random-effects meta-analyses of the weighted beta coefficients. RESULTS: Falls in the past year were reported in 21.4% of individuals. During a follow-up of 9,102,207 person-years, 87,352 fractures occurred of which 19,509 were hip fractures. A previous fall was associated with a significantly increased risk of any clinical fracture both in women (hazard ratio (HR) 1.42, 95% confidence interval (CI) 1.33-1.51) and men (HR 1.53, 95% CI 1.41-1.67). The HRs were of similar magnitude for osteoporotic, major osteoporotic fracture, and hip fracture. Sex significantly modified the association between previous fall and fracture risk, with predictive values being higher in men than in women (e.g., for major osteoporotic fracture, HR 1.53 (95% CI 1.27-1.84) in men vs. HR 1.32 (95% CI 1.20-1.45) in women, P for interaction = 0.013). The HRs associated with previous falls decreased with age in women and with duration of follow-up in men and women for most fracture outcomes. There was no evidence of an interaction between falls and BMD for fracture risk. Subsequent risk for a major osteoporotic fracture increased with each additional previous fall in women and men. CONCLUSIONS: A previous self-reported fall confers an increased risk of fracture that is largely independent of BMD. Previous falls should be considered as an additional risk factor in future iterations of FRAX to improve fracture risk prediction.

[Amyotrophic lateral sclerosis (ALS) from the perspective of Primary Care. Epidemiology and clinical-care characteristics]. / La esclerosis lateral amiotrófica (ELA) desde la Atención Primaria. Epidemiología y características clínico-asistenciales.

Amyotrophic Lateral Sclerosis (ALS) is a rare disease in primary care (PC), it represents a challenge for the family doctor, especially in home care. OBJECTIVE: To know the incidence and prevalence of ALS in an area of ??PA management, the clinical characteristics and use of health resources. DESIGN: Observational study. LOCATION: PC-Direction Costa de Ponent, South Metropolitan Health Region, Barcelona, Catalonia, Spain. PARTICIPANTS: Patients with ALS ≥18 years diagnosed until 03/01/2017. Main measurements Age, sex, characteristics: form of appearance (spinal, bulbar, others), interval between onset of symptoms and diagnosis, percutaneous gastrostomy carriers, ventilation non-invasive or invasive. Identification in PC as a Complex Chronic Patient or with palliative needs (CCP). Inclusion in home care programs (PAD). Model of attention hospitable. RESULTS: 81 patients, mean age 65.6 years (± 11.7), men 49.4%. Shape of onset: spinal 69%, bulbar 21%, another 4%. Interval between the onset of symptoms and diagnosis 12 months. Identified as a CCP 13.6%, 29 patients (35.8%) included in PAD. Attended in comprehensive hospital model 79 patients (97.5%). Prevalence 6.1/100,000 inhabitants in 2017. Annual incidence between 1.2 cases/100,000 inhabitants/year in 2012 and 3.5 cases/100,000 inhabitants/year in 2016. CONCLUSIONS: The use of percutaneous gastrostomy in ALS favors the identification as CCP or with palliative needs and inclusion in PAD. The use of non-invasive ventilation favors inclusion in PAD. The incidence and prevalence data for ALS are higher than those described above in the same area. Early identification is necessary of these patients in the chronic care models in PC teams.

Rationale of the Spanish FRAX model in decision-making for predicting osteoporotic fractures: an update of FRIDEX cohort of Spanish women.

BACKGROUND: The FRAX® tool estimates the risk of a fragility fracture among the population and many countries have been evaluating its performance among their populations since its creation in 2007. The purpose of this study is to update the first FRIDEX cohort analysis comparing FRAX with the bone mineral density (BMD) model, and its predictive abilities. METHODS: The discriminatory ability of the FRAX was assessed using the 'area under curve' of the receiver operating characteristic (AUC-ROC). Predictive ability was assessed by comparing estimated risk fractures with incidence fractures after a 10-year follow up period. RESULTS: One thousand three hundred eight women ≥ 40 and ≤ 90 years followed up during a 10-year period. The AUC for major osteoporotic fractures using FRAX without DXA was 0.686 (95 % CI 0.630-0.742) and using FN T-score of DXA 0.714 (95 % CI 0.661-0.767). Using only the traditional parameters of DXA (FN T-score), the AUC was 0.706 (95 % CI 0.652-0.760). The AUC for hip osteoporotic fracture was 0.883 (95 % CI 0.827-0.938), 0.857 (95 % CI 0.773-0.941), and 0.814 (95 % CI 0.712-0.916) respectively. For major osteoporotic fractures, the overall predictive value using the ratio Observed fractures/Expected fractures calculated with FRAX without T-score of DXA was 2.29 and for hip fractures 2.28 and with the inclusion of the T-score 2.01 and 1.83 respectively. However, for hip fracture in women < 65 years was 1.53 and 1.24 respectively. CONCLUSIONS: The FRAX tool has been found to show a good discriminatory capacity for detecting women at high risk of fragility fracture, and is better for hip fracture than major fracture. The test of sensibility shows that it is, at least, not inferior than when using BMD model alone. The predictive capacity of FRAX tool needs some adjustment. This capacity is better for hip fracture prediction and better for women < 65 years. Further studies in Catalonia and other regions of Spain are needed to fine tune the FRAX tool's predictive capability.

[Prevalence of non-alcoholic fatty liver disease in a population with elevated transaminases and level of accuracy of the diagnosis in Primary Care]. / Prevalencia de la esteatosis hepática no alcohólica en población con hipertransaminasemia y grado de adecuación del diagnóstico registrado en atención primaria.

UNLABELLED: Nonalcoholic fatty liver disease (NAFLD) is the most common cause of elevated transaminases in adults. AIM: Determine the prevalence of NASH in patients with sustained hypertransaminasemia, and Know the adequacy of the registered in Primary Care (AP) diagnosis. MATERIAL AND METHODS: 1) Cross-sectional study with a random sample of patients with elevated alanine aminotransferase (ALT) held (ALT> 32 for ≥6 months), ruling out other causes of liver disease, according to clinical, laboratory and ultrasound scan criteria in AP and 2) cross-sectional description of all cases diagnosed with NASH recorded (K76 - ICD10) with diagnostic adequacy analysis according to standard criteria. RESULTS: 290 patients were analyzed: 76 were diagnosed as NASH (26.1%), 44 women (57.9%). Multivariate analysis adjusted for age and sex showed no association between NASH and male gender (OR: 0.5; CI95%: 0.3-0.9), diabetes mellitus (DM) (OR: 2.42; CI95%: 1.2-4.9) and hypertension blood pressure (HBP) (OR: 3.07; CI 95% 1.6-5.6). Of the 209 diagnosed with NASH record: 51 (24.4%) met the criteria for NASH. The rest had insufficient records. HIGHLIGHTS: 53.1% lacked sustained hypertransaminasemia; 48% of viral serology; 11% supported and 53.1% abdominal ultrasound registration of alcohol. CONCLUSIONS: Severe NASH is frequent among patients with sustained hypertransaminasemia. The DM and hypertension significantly increase the risk of NASH. The diagnosis of NASH is recorded without considering all criteria and mainly NASH made by ultrasonography. They should unify diagnostic criteria in the register of NASH.

An increased rate of falling leads to a rise in fracture risk in postmenopausal women with self-reported osteoarthritis: a prospective multinational cohort study (GLOW).

OBJECTIVES: Patients with osteoarthritis have increased bone mass but no decrease in fractures. The association between self-reported osteoarthritis and incident falls and fractures was studied in postmenopausal women. METHODS: The Global Longitudinal Study of Osteoporosis in Women is a prospective multinational cohort of 60,393 non-institutionalised women aged ≥55 years who had visited primary care practices within the previous 2 years. Questionnaires were mailed at yearly intervals. Patients were classified as having osteoarthritis if they answered yes to the question, 'Has a doctor or other health provider ever said that you had osteoarthritis or degenerative joint disease?', and this was validated against primary care records in a subsample. Information on incident falls, fractures and covariates was self-reported. Cox and Poisson models were used for incident fractures and number of falls, respectively, to compute hazard ratios (HRs) and rate ratios (RRs) for baseline osteoarthritis status. RESULTS: Of 51 386 women followed for a median of 2.9 years (interquartile range 2.1-3.0), 20 409 (40%) reported osteoarthritis. The adjusted HR for osteoarthritis predicting fracture was 1.21 (95% CI 1.13 to 1.30; p<0.0001) and the adjusted RR for falls was 1.24 (95% CI 1.22 to 1.26; p<0.0001). However, the association between osteoarthritis and fracture was not significant after adjustment for incident falls (HR 1.06 (95% CI 0.98 to 1.15; p=0.13)). CONCLUSIONS: Postmenopausal women with self-reported osteoarthritis have a 20% increased risk of fracture and experience 25% more falls than those without osteoarthritis. These data suggest that increased falls are the causal pathway of the association between osteoarthritis and fractures.

FRAX® tool, the WHO algorithm to predict osteoporotic fractures: the first analysis of its discriminative and predictive ability in the Spanish FRIDEX cohort.

BACKGROUND: The WHO has recently published the FRAX® tool to determine the absolute risk of osteoporotic fracture at 10 years. This tool has not yet been validated in Spain. METHODS/DESIGN: A prospective observational study was undertaken in women in the FRIDEX cohort (Barcelona) not receiving bone active drugs at baseline. Baseline measurements: known risk factors including those of FRAX® and a DXA. Follow up data on self-reported incident major fractures (hip, spine, humerus and wrist) and verified against patient records. The calculation of absolute risk of major fracture and hip fracture was by FRAX® website. This work follows the guidelines of the STROBE initiative for cohort studies. The discriminative capacity of FRAX® was analyzed by the Area Under Curve (AUC), Receiver Operating Characteristics (ROC) and the Hosmer-Lemeshow goodness-of-fit test. The predictive capacity was determined using the ratio of observed fractures/expected fractures by FRAX® (ObsFx/ExpFx). RESULTS: The study subjects were 770 women from 40 to 90 years of age in the FRIDEX cohort. The mean age was 56.8 ± 8 years. The fractures were determined by structured telephone questionnaire and subsequent testing in medical records at 10 years. Sixty-five (8.4%) women presented major fractures (17 hip fractures). Women with fractures were older, had more previous fractures, more cases of rheumatoid arthritis and also more osteoporosis on the baseline DXA. The AUC ROC of FRAX® for major fracture without bone mineral density (BMD) was 0.693 (CI 95%; 0.622-0.763), with T-score of femoral neck (FN) 0.716 (CI 95%; 0.646-0.786), being 0.888 (CI 95%; 0.824-0.952) and 0.849 (CI 95%; 0.737-0.962), respectively for hip fracture. In the model with BMD alone was 0.661 (CI 95%; 0.583-0.739) and 0.779 (CI 95%; 0.631-0.929). In the model with age alone was 0.668 (CI 95%; 0.603-0.733) and 0.882 (CI 95%; 0.832-0.936). In both cases there are not significant differences against FRAX® model. The overall predictive value for major fracture by ObsFx/ExpFx ratio was 2.4 and 2.8 for hip fracture without BMD. With BMD was 2.2 and 2.3 respectively. Sensitivity of the four was always less than 50%. The Hosmer-Lemeshow test showed a good correlation only after calibration with ObsFx/ExpFx ratio. CONCLUSIONS: The current version of FRAX® for Spanish women without BMD analysed by the AUC ROC demonstrate a poor discriminative capacity to predict major fractures but a good discriminative capacity for hip fractures. Its predictive capacity does not adjust well because leading to underdiagnosis for both predictions major and hip fractures. Simple models based only on age or BMD alone similarly predicted that more complex FRAX® models.

Light Microscopy and Proteomic Patterns of Ovulation in Cervical Mucus.

There is an increasing number of couples interested in identifying the fertile window for the purpose of conceiving. From what has been published so far, it can be concluded that there are no reliable methods to predict ovulation, and, therefore, to predict the fertile window. Proteins of the cervical mucus (CM) could behave as biomarkers to allow the early and precise identification of ovulation. CM samples were collected from the lumen of the cervical canal from women of reproductive age, on three different days of the same menstrual cycle. Samples were first analyzed and classified by light microscopy. High-resolution mass spectrometry and bioinformatic analysis were performed afterwards to determine the in vivo changes of CM protein composition. CM underwent cyclical changes in its biophysical composition, which were evidenced by changes in the crystallographic patterns observed under the light microscope. The proteomic analysis revealed changes in the protein composition of CM along the cycle. Twenty-five out of the forty-eight total proteins identified could become potential biomarkers of ovulation. The coordinated changes in the composition of the CM around the time of ovulation could be happening to specifically grant access to a foreign body, such as the sperm might be.

Measuring health-related quality of life in men with osteoporosis or osteoporotic fracture.

BACKGROUND: Osteoporosis is a serious health problem that worsens the quality of life and the survival rate of individuals with this disease on account the osteoporotic fractures. Studies have long focused on women, and its presence in men has been underestimated. While many studies conducted in different countries mainly assess health-related quality of life and identify fracture risks factors in women, few data are available on a Spanish male population. METHODS/DESIGN: Observational study. STUDY POPULATION: Men ≥ 40 years of age with/without diagnosed osteoporosis and with/without osteoporotic fracture included by their family doctor. MEASUREMENTS: The relationship between customary clinical risk factors for osteoporotic fracture and health-related quality of life in a Spanish male population. A telephone questionnaire on health-related quality of life is made. STATISTICAL ANALYSIS: The association between qualitative variables will be assessed by the Chi-square test. The distribution of quantitative variables by Student's t-test. If the conditions for using this test are not met, the non-parametric Mann-Whitney's U test will be used.The validation of the results obtained by the FRAX™ tool will be performed by way of the Hosmer-Lemeshow test and by calculating the area under the Receiver Operating Characteristic (ROC) curve (AUC). All tests will be performed with a confidence intervals set at 95%. DISCUSSION: The applicability and usefulness of Health-related quality of life (HRQOL) studies are well documented in many countries. These studies allow implementing cost-effective measures in cases of a given disease and reducing the costly consequences derived therefrom. This study attempts to provide objective data on how quality of life is affected by the clinical aspects involved in osteoporosis in a Spanish male population and can be useful as well in cost utility analyses conducted by health authorities.The sample selected is not based on a high fracture risk group. Rather, it is composed of men in the general population, and accordingly comparisons should not lead to erroneous interpretations.A possible bias correction will be ensured by checking reported fractures against healthcare reports and X-rays, or by consulting health care centers as applicable.

Prediction of absolute risk of fragility fracture at 10 years in a Spanish population: validation of the WHO FRAX ™ tool in Spain.

BACKGROUND: Age-related bone loss is asymptomatic, and the morbidity of osteoporosis is secondary to the fractures that occur. Common sites of fracture include the spine, hip, forearm and proximal humerus. Fractures at the hip incur the greatest morbidity and mortality and give rise to the highest direct costs for health services. Their incidence increases exponentially with age.Independently changes in population demography, the age - and sex- specific incidence of osteoporotic fractures appears to be increasing in developing and developed countries. This could mean more than double the expected burden of osteoporotic fractures in the next 50 years. METHODS/DESIGN: To assess the predictive power of the WHO FRAX™ tool to identify the subjects with the highest absolute risk of fragility fracture at 10 years in a Spanish population, a predictive validation study of the tool will be carried out. For this purpose, the participants recruited by 1999 will be assessed. These were referred to scan-DXA Department from primary healthcare centres, non hospital and hospital consultations. STUDY POPULATION: Patients attended in the national health services integrated into a FRIDEX cohort with at least one Dual-energy X-ray absorptiometry (DXA) measurement and one extensive questionnaire related to fracture risk factors. MEASUREMENTS: At baseline bone mineral density measurement using DXA, clinical fracture risk factors questionnaire, dietary calcium intake assessment, history of previous fractures, and related drugs. Follow up by telephone interview to know fragility fractures in the 10 years with verification in electronic medical records and also to know the number of falls in the last year. The absolute risk of fracture will be estimated using the FRAX™ tool from the official web site. DISCUSSION: Since more than 10 years ago numerous publications have recognised the importance of other risk factors for new osteoporotic fractures in addition to low BMD. The extension of a method for calculating the risk (probability) of fractures using the FRAX™ tool is foreseeable in Spain and this would justify a study such as this to allow the necessary adjustments in calibration of the parameters included in the logarithmic formula constituted by FRAX™.

[Coordination between primary and specialized care in gastroenterology is insufficient. A survey of gastroenterologists and general practitioners]. / La coordinación entre atención primaria y especializada de digestivo es insuficiente. Resultados de una encuesta realizada a gastroenterólogos y médicos de familia.

BACKGROUND AND OBJECTIVES: Collaboration between general practitioners (GPs) and specialists is considered crucial to provide high-quality healthcare. The objective of this study was to analyze the relationship between gastroenterologists and GPs in regional hospitals and their referring primary care centers in Catalonia (Spain). MATERIALS AND METHODS: A descriptive, observational, cross-sectional study was carried out using anonymous questionnaires between January and April 2008. RESULTS: A total of 314 surveys were administered (261 GPs and 53 gastroenterologists). The overall relationship was considered highly deficient or insufficient by 62.3% of gastroenterologists (95% CI, 47.9-74.9) and by 55.6% of GPs (95% CI, 49.3-61.7). More than half (56.6%) of the gastroenterologists did not know any GPs, or only a very few, and the situation was the same for 80.4% of GPs. Sixty-four percent of gastroenterologists considered that the quality of care for digestive diseases in primary care was highly deficient or insufficient while 21.1% of GPs considered that the care provided by gastroenterologists was highly deficient or insufficient. The perception of healthcare in both primary and specialized settings was substantially better when there was good interaction between gastroenterologists and GPs. CONCLUSIONS: Practitioners acknowledge that the degree of interaction between different levels of healthcare is insufficient. Moreover, gastroenterologists consider that the management of digestive diseases in primary care is deficient. Establishing a personal relationship between the two types of practitioners substantially improves mutual assessment.

High Effectiveness of a 14-Day Concomitant Therapy for Helicobacter pylori Treatment in Primary Care. An Observational Multicenter Study.

BACKGROUND: The current cure rates with triple therapy combining a proton-pump inhibitor, amoxicillin and clarithromycin are unacceptably low. AIMS: To evaluate the efficacy of a 14-day concomitant therapy as an empirical first-line treatment for curing Helicobacter pylori (Hp) infection in primary care. METHODS: Patients from six primary care centers in Catalonia -Spain- were included consecutively. Hp status pre and post treatment was assessed according to local clinical practice protocol. A 14-day concomitant therapy (amoxicillin 1 g, clarithromycin 500 mg and metronidazole 500 mg plus omeprazole 20 mg, all drugs administered twice daily) was prescribed. Adherence to therapy and adverse events were assessed by personal interview. RESULTS: 112 patients were enrolled. Mean age was 46.7 ± 16.1 years. Main indication for treatment was non-investigated dyspepsia (83%). Hp eradication was achieved in 100 of the 112 patients. Eradication rates were 89.3% (95% CI: 81.7-94.1) by intention-to-treat (ITT) analysis and 91.7% (95% CI; 84.6-95.9) per protocol (PP). No major side effects were reported; 104 (92.8%) patients complete the treatment. Forty-seven patients (42%) complained of mild side effects (metallic taste, nausea). Low adherence to treatment (p = 0.004) and significant adverse events (p = 0.004) were the variables associated with treatment failure. CONCLUSIONS: In primary care, a 14-day concomitant therapy is highly effective and well tolerated.

Effectiveness of the Epley manoeuvre in posterior canal benign paroxysmal positional vertigo: a randomised clinical trial in primary care.

BACKGROUND: Evidence on the effectiveness of the Epley manoeuvre in primary care is scarce. AIM: To evaluate effectiveness at 1 week, 1 month, and 1 year of a single Epley manoeuvre versus a sham manoeuvre in primary care. DESIGN AND SETTING: Multicentre, double-blind randomised controlled trial in two primary care practices in Spain from November 2012 to January 2015. METHOD: Patients were ≥18 years diagnosed with subjective or objective posterior benign paroxysmal positional vertigo (vertigo only, or vertigo and nystagmus after a Dix-Hallpike test [DHT]). The intervention group received the Epley manoeuvre, and the control group received a sham manoeuvre. Betahistine was prescribed following the same regimen in both groups. The main outcome measures were the DHT result classified as negative (neither vertigo nor nystagmus) or positive. Positive results were further divided into a positive result for both vertigo and nystagmus (positive DHT with nystagmus), and a positive result for vertigo only (positive DHT without nystagmus); self-reported resolution of vertigo; and self-reported severity of vertigo evaluated on a 10-point Likert scale (10 = worst imaginable vertigo). RESULTS: In total, 134 patients were randomised to either the intervention group (n = 66) or the sham group (n = 68). The intervention group showed better results in the unadjusted analyses at 1 week, with a lower rate of positive DHT with nystagmus (P = 0.022). A positive baseline DHT with nystagmus was associated with a reduction in vertigo severity (marginal effect for 10-point Likert-like question -1.73, 95% confidence interval [CI] = -2.95 to -0.51) and better positive DHT rates in the intervention group (adjusted odds ratio 0.09, 95% CI = 0.01 to 0.92) in the multivariate analyses. CONCLUSION: A single Epley manoeuvre performed in primary care is an effective treatment for reversing a positive DHT and reducing vertigo severity in patients with baseline nystagmus in the DHT.

[Management of Helicobacter pylori infection in primary care in Spain]. / Manejo de la infección por Helicobacter pylori en atención primaria en España.

OBJECTIVE: The indications on when and how to diagnose and treat ulcerative disease and Helicobacter pylori infection are reasonably clear. The aim of this study was to evaluate the management of H. pylori infection and access to diagnostic tests in primary care. MATERIAL AND METHODS: We performed an observational, cross-sectional study. An anonymous questionnaire was sent to Spanish primary care physicians throughout Spain. Compliance with the major consensus conference recommendations on H. pylori treatment was evaluated. RESULTS: The questionnaire was completed by 991 primary care physicians. A total of 87.7% of respondents reported they had indicated eradication therapy at least once during the previous year: 79.9% for duodenal ulcer, 75.3% for gastric ulcer, and 18.3% for gastroesophageal reflux disease. The treatment schedule was correct according to the consensus in 74.7% of the responses. However, 29% prescribed 14-day therapy, which is longer than the recommended duration. Sixty-seven per cent of practitioners maintained continuous or intermittent anti-secretory treatment in asymptomatic ulcerous patients and did not indicate H. pylori eradication therapy. The availability of different tests was as follows: 64.7% of respondents had access to endoscopy, 67.4% to urea breath test, 59.6% to serology, and 11.9% to the H. pylori stool antigen test. There were substantial regional variations in access to diagnostic tests. CONCLUSIONS: Management of H. pylori infection is reasonably well adapted to consensus recommendations. Nevertheless, there is marked geographic variation and substantial restrictions in access to diagnostic tests, which hampers application of the recommendations.

Proteomic Markers in Cervical Mucus.

BACKGROUND: Cervical Mucus (CM) is a viscous fluid produced by the secretory cells of the cervical crypts. The CM undergoes modifications throughout the cycle that make it have different biochemical and biophysical characteristics, becoming a crucial element for the identification of ovulation. Since CM is rich in secreted proteins, it may represent moreover a source of biomarkers for female reproductive tract diseases. OBJECTIVE: This review is an attempt to collect relevant knowledge about the physicochemical properties and functions of the cervical mucus, including its important role as a clinical marker of female fertility, and draws attention to CM as a source of potential proteomic biomarkers. FINDINGS: All the assessed studies evidenced that the observation of the CM allows the identification of the days with the highest probability of pregnancy. CM proteome changes throughout the menstrual cycle have been revealed. Few proteomic studies on the constitutive protein composition of CM of fertile women have been conducted to date. In the CM of patients affected by endometriosis have been identified some proteins that could represent potential biomarkers of the disease. CONCLUSION: There is still limited knowledge about the physicochemical properties and functions of the CM and how these undergo to changes during menstrual cycle. CM is a reliable predictor of fertility. Further characterization of CM proteins would contribute to a better understanding of the key role they have on fertility, reproduction and biological regulation. CM may represent moreover a source of biomarkers for gynecological diseases.

[FRAX® thresholds to identify people with high or low risk of osteoporotic fracture in Spanish female population]. / Umbrales de FRAX(®) para identificar personas con alto o bajo riesgo de fractura osteoporótica en población femenina española.

BACKGROUND AND OBJECTIVE: To detect FRAX(®) threshold levels that identify groups of the population that are at high/low risk of osteoporotic fracture in the Spanish female population using a cost-effective assessment. PATIENTS AND METHODS: This is a cohort study. Eight hundred and sixteen women 40-90 years old selected from the FRIDEX cohort with densitometry and risk factors for fracture at baseline who received no treatment for osteoporosis during the 10 year follow-up period and were stratified into 3 groups/levels of fracture risk (low<10%, 10-20% intermediate and high>20%) according to the real fracture incidence. RESULTS: The thresholds of FRAX(®) baseline for major osteoporotic fracture were: low risk<5; intermediate ≥ 5 to <7.5 and high ≥ 7.5. The incidence of fracture with these values was: low risk (3.6%; 95% CI 2.2-5.9), intermediate risk (13.7%; 95% CI 7.1-24.2) and high risk (21.4%; 95% CI12.9-33.2). The most cost-effective option was to refer to dual energy X-ray absorptiometry (DXA-scan) for FRAX(®)≥ 5 (Intermediate and high risk) to reclassify by FRAX(®) with DXA-scan at high/low risk. These thresholds select 17.5% of women for DXA-scan and 10% for treatment. With these thresholds of FRAX(®), compared with the strategy of opportunistic case finding isolated risk factors, would improve the predictive parameters and reduce 82.5% the DXA-scan, 35.4% osteoporosis prescriptions and 28.7% cost to detect the same number of women who suffer fractures. CONCLUSIONS: The use of FRAX ® thresholds identified as high/low risk of osteoporotic fracture in this calibration (FRIDEX model) improve predictive parameters in Spanish women and in a more cost-effective than the traditional model based on the T-score ≤ -2.5 of DXA scan.
