Consenso sobre criterios y conjunto mínimo de datos para la derivación de pacientes candidatos a teleconsulta de nutrición enteral domiciliaria: proyecto TElENUT / Consensus on criteria and minimum data set for the referral of candidate patients for home enteral nutrition teleconsultation: TELENUT project

Introducción: la teleconsulta es una herramienta asistencial útil en el manejo multidisciplinar de pacientes con indicación de nutrición enteral domiciliaria (NED). El empleo de diferentes herramientas de teleconsulta de NED, como ocurre en el Sistema Andaluz de Salud (SAS), conlleva heterogeneidad en los procesos de derivación entre los servicios de Atención Primaria (AP) y hospitalaria en una misma región. Objetivos: consensuar perfiles de pacientes y conjunto de datos mínimos necesarios para garantizar una derivación adecuada a la teleconsulta de NED, independientemente de la herramienta existente. Estos aspectos consensuados en Andalucía pueden servir de referencia en otras regiones. Métodos: se siguieron tres pasos consecutivos: a) revisión no sistemática de la literatura indexada sobre la teleconsulta en nutrición clínica en España; b) encuesta para conocer la implementación y las necesidades no satisfechas de las herramientas de teleconsulta en los hospitales públicos andaluces; y c) reuniones de trabajo y consenso de 14 profesionales sanitarios de AP (n = 4) y endocrinología y nutrición clínica hospitalaria (n = 10). Resultados: se consensuaron tres formularios de derivación en los que se definieron tres perfiles de pacientes, con el correspondiente conjunto mínimo de datos necesario para solicitar la teleconsulta de NED. El equipo de AP debe proporcionar este conjunto mínimo de datos al especialista en nutrición clínica a través de una herramienta de teleconsulta, implementada en el SAS. Conclusiones: tres formularios consensuados entre profesionales sanitarios involucrados en el proceso de derivación sirven para estandarizar la solicitud de teleconsulta de NED entre equipos asistenciales en función de perfiles de pacientes.(AU)

Introduction: teleconsultation is a useful healthcare tool in the multidisciplinary management of patients with indications of home enteral nutrition (HEN). The use of different teleconsultation platforms, as it happens in the Andalusian Health System (SAS), results in heterogeneous referral processes between Primary Care and hospital services in the same region. Objectives: to establish a consensus on patient profiles and the minimum data set necessary to guarantee an adequate referral to NED teleconsultation regardless of the existing platform. These agreed aspects in Andalusia can serve as a reference in other regions. Methods: three consecutive steps were followed: a) non-systematic review of the indexed literature on teleconsultation in clinical nutrition in Spain; b) survey to know the implementation and unmet needs of teleconsultation platforms in Andalusian public hospitals; and c) working meetings and consensus of 14 health professionals of Primary Care (n = 4) and endocrinology and hospital clinical nutrition (n = 10). Results: three referral forms were agreed in which three patient profiles were defined, with the corresponding minimum set of data necessary to request NED teleconsultation. The Primary Care team should provide this set of data to the clinical nutrition specialist via a teleconsultation platform, implemented in the SAS. Conclusions: three agreed forms between healthcare professionals involved in the referral process serve to standardize the request for teleconsultation of NED between healthcare teams based on patient profiles.(AU)

Prognostic value of bioelectrical impedance analysis in head and neck cancer patients undergoing radiotherapy: a VALOR® study.

Introduction: Bioelectrical impedance analysis (BIA) serves as a method to estimate body composition. Parameters such as phase angle (PA), standardized phase angle (SPA), body mass cell (BCM), BCM index (BCMI), and fat-free mass (FFM) might significantly impact the prognosis of head and neck cancer (HNC) patients. The present study aimed to investigate whether bioelectrical parameters can be used to predict survival in the HNC population and establish the optimal cutoff points for predictive accuracy. Methods: A multicenter observational study was performed across 12 tertiary hospitals in Andalusia (a region from the south of Spain). A total of 494 patients diagnosed with HNC between 2020 and 2022 at different stages were included in this study, with a minimum follow-up period of 12 months. The BIA assessment was carried out during the first 2 weeks of radical radiotherapy treatment with chemotherapy or other systemic treatments. A multivariate logistic regression analysis of overall survival, complications, hospital admission, and palliative care and its relationship with BIA nutritional assessment was performed. Results: Significant prognostic factors identified in the multivariable analysis encompassed phase angle (PA), standardized phase angle (SPA), body cell mass (BCM), and BCM index (BCMI). Lower PA and BCM values were significantly associated with adverse clinical outcomes. A BCM threshold above 17 kg/m2 was the most significant predictor for predicting survival within the overall HNC population. The PA values of <5.1° in male and <4.8° in female patients showed the best predictive potential for mortality. Increased PA (as a continuous variable) demonstrated a significantly reduced risk for mortality (OR, 0.64; 95% CI, 0.43-0.94; p < 0.05) and a decreased likelihood of hospital admission (OR, 0.75; 95% CI, 0.52-1.07; p < 0.05). Higher BCM correlated with a lower risk of mortality (OR, 0.88; 95% CI, 0.80-0.96; p < 0.01) and a diminished probability of hospital admission (OR, 0.91; 95% CI, 0.83-0.99; p < 0.05). Conclusion: BIA is a crucial tool in the nutritional assessment of HNC patients. BCM and PA are the main bioelectrical parameters used to predict clinical outcomes in this population. Future studies are needed to validate BIA variables in a large cohort to ensure whether early intensification of nutritional treatment would improve survival.

PPARγ Gene as a Possible Link between Acquired and Congenital Lipodystrophy and its Modulation by Dietary Fatty Acids.

Lipodystrophy syndromes are rare diseases that could be of genetic or acquired origin. The main complication of lipodystrophy is the dysfunction of adipose tissue, which leads to an ectopic accumulation of triglycerides in tissues such as the liver, pancreas and skeletal muscle. This abnormal fat distribution is associated with hypertriglyceridemia, insulin resistance, liver steatosis, cardiomyopathies and chronic inflammation. Although the origin of acquired lipodystrophies remains unclear, patients show alterations in genes related to genetic lipodystrophy, suggesting that this disease could be improved or aggravated by orchestrating gene activity, for example by diet. Nowadays, the main reason for adipose tissue dysfunction is an imbalance in metabolism, caused in other pathologies associated with adipose tissue dysfunction by high-fat diets. However, not all dietary fats have the same health implications. Therefore, this article aims to summarize the main genes involved in the pathophysiology of lipodystrophy, identify connections between them and provide a systematic review of studies published between January 2017 and January 2022 of the dietary fats that can modulate the development of lipodystrophy through transcriptional regulation or the regulation of protein expression in adipocytes.

Association between low bone mineral density and periodontitis in generally healthy perimenopausal women.

BACKGROUND: The association between low bone mineral density (BMD) and periodontitis in perimenopausal women is controversial. The purpose of this study was to determine whether osteoporosis or osteopenia is associated with periodontal disease in a population of adult women. METHODS: A sample of over-45-year-old women with or without low BMD underwent lumbar spine and hip bone densitometry and a complete periodontal examination. The extent/severity or absence of periodontal disease was noted using two different case definitions. Data were gathered on socio-economic status, medication history, systemic co-morbidities, alcohol or tobacco use as well as serum levels of calcium and vitamin D. RESULTS: One hundred seventy three women aged between 45 and 72 years old were recruited with a mean age of 57.8 years. One hundred and three had decreased BMD (61 with osteoporosis and 42 with osteopenia) and 70 were healthy. Moderate or severe periodontitis was present in 52.6% of the women. Multivariate analysis showed a clear association between low BMD and periodontitis, but only in women above 58 years old and independent of tobacco consumption or oral hygiene. CONCLUSION: In this sample of generally healthy perimenopausal women, low BMD was associated with clinical attachment level (CAL). Women over 58 years old with decreased BMD presented with a higher mean percentage of sites with CAL ≥ 4 mm as well as CAL ≥ 6 mm when compared to controls, independent of active smoking status or poor oral hygiene.

25-hydroxyvitamin D levels in the early healing of osteoporotic hip fracture and their relationship with clinical outcome / Niveles de 25-hidroxivitamina D en la fase precoz de la fractura osteoporótica de cadera y su relación con los resultados clínicos

INTRODUCTION: vitamin D is involved in recovery after an osteoporotic hip fracture (OHF). Previous studies have reported decreased serum vitamin D levels during fracture healing. OBJECTIVES: our aim was to evaluate: a) serum 25-hydroxyvitamin D3 (25OHD3) levels in patients with OHF at hospital admission and 8 days post-admission, and b) the relationship between 25OHD levels and clinical outcomes. METHODS: a prospective study including 66 patients aged over 65 years hospitalized for OHF. We gathered data on baseline demographic characteristics, medical history, Mini Mental State (MMS) assessment, Activities of Daily Living (ADL) results, nutritional assessment, and type of fracture and surgery. Laboratory results were collected on bone biomarkers, albumin, 25OHD3, and IL6. Clinical outcomes included length of stay, complications, and mortality. In the statistical analysis, a t-test was used for continuous variables and a chi-square test for qualitative variables. Linear regression models were used for the multivariate analysis, adjusted for covariates. RESULTS: our study population had low serum vitamin D levels at admission, with a mean [(standard error of the mean (SEM)] of 12.04 (1.03) ng/mL. Both 25OHD3 and interleukin 6 (IL-6) levels significantly declined (p < 0.001) during the early post-fracture phase. A greater decline in 25OHD3 levels was significantly associated with longer hospital stay (p = 0.042, multivariate analysis). Serum 25OHD3 levels were also associated with cognitive status as assessed using the MMS exam. CONCLUSIONS: 25OHD3 levels were reduced in OHF patients at admission, and significantly decreased during the first 8 days post-admission. 25OHD3 levels were associated with MMS-assessed cognitive status. A greater decline in serum 25OHD3 was associated with a longer hospital stay

INTRODUCCIÓN: la vitamina D se ha relacionado con la recuperación tras la fractura osteoporótica de cadera (FOC). Estudios previos muestran un descenso de los niveles de vitamina D en la fase precoz tras la fractura. OBJETIVOS: evaluar: a) los niveles séricos de 25-hidroxivitamina D3 (25OHD3) al ingreso y a los 8 días del ingreso en hospitalizados por FOC; b) la relación de los niveles de 25OHD3 con los resultados clínicos, así como con el nivel cognitivo y funcional. MÉTODOS: estudio prospectivo de 66 pacientes (> 65 años) ingresados por FOC. Se estudiaron las características demográficas, los antecedentes personales, la valoración nutricional, el test Mini Mental State (MMS), el cuestionario Activities of Daily Living (ADL), el tipo de fractura y de cirugía, y parámetros bioquímicos del metabolismo óseo, la 25OHD3, la albúmina y la interleuquina 6. Como resultados clínicos se analizaron: estancia hospitalaria, complicaciones y mortalidad durante el ingreso. El análisis estadístico consistió en: a) prueba de la t para las variables continuas y χ2 para las cualitativas; b) análisis multivariable utilizando modelos de regresión lineal ajustados según el análisis de la covarianza. RESULTADOS: la población estudiada muestra niveles bajos de 25OHD3 al ingreso: media [± error estándar de la media (EEM)] = 12,04 (1,03) ng/mL. Durante el ingreso, 25OHD3 e interleuquina 6 decrecen significativamente (p < 0,001). El descenso de 25OHD3 se asocia con la estancia hospitalaria (p = 0,042 en análisis multivariable). Los valores disminuidos de 25OHD3 se asocian a un bajo nivel cognitivo (p = 0,042). CONCLUSIONES: los pacientes ingresados por fractura osteoporótica de cadera tienen niveles bajos de 25OHD3 que decrecen significativamente tras 8 días de ingreso. El descenso de 25OHD3 se asocia significativamente a la estancia hospitalaria. Los niveles disminuidos de 25OHD3 se asocian a un peor estado cognitivo evaluado mediante el MMS

Effects of Probiotics on Metabolic Syndrome: A Systematic Review of Randomized Clinical Trials.

The aim of this systematic review is to evaluate whether the use of probiotics has any effect on the components of metabolic syndrome (MetS) before patients develop type 2 diabetes. A qualitative systematic review, following the Cochrane methodology, and a comprehensive literature search of randomized controlled trials (RCTs) were conducted in PubMed and Scopus from inception until 4 July 2019. According to our inclusion criteria, nine clinical studies were finally analyzed, corresponding to six RCTs. Probiotics intake in patients with MetS resulted in improvements in body mass index, blood pressure, glucose metabolism, and lipid profile in some studies. Regarding inflammatory biomarkers, probiotics also positively affected the soluble vascular cell adhesion molecule 1 (sVCAM-1), interleukine-6 (IL-6), tumor necrosis factor α (TNF-α), vascular endothelial growth factor (VEGF), and thrombomodulin. Despite the diversity of the published studies, the intake of probiotics for patients with MetS may offer a discrete improvement in some of the clinical characteristics of the MetS and a decrease in inflammatory biomarkers. Nevertheless, these beneficial effects seem to be marginal compared to drug therapy and a healthy lifestyle and clinically non-relevant.

Glucagon-like peptide 1 and Glucagon-like peptide 2 in relation to osteoporosis in non-diabetic postmenopausal women.

Osteoporosis results from an imbalance in bone remodeling, which is known to follow a circadian rhythm determined by a functional relationship between intestine and bone tissue. Specific intestinal peptides have been identified as mediators. Glucagon-like peptide 1 and glucagon-like peptide 2, have been associated with bone health. Our main objective was to determine whether postprandial plasma levels of glucagon-like peptide 1, glucagon-like peptide 2 and dipeptidyl-peptidase 4 activity, are associated with osteoporosis in non-diabetic postmenopausal women. We studied non-diabetic postmenopausal women with osteoporosis diagnosed by dual-energy X-ray absorptiometry (cases, n = 43) and age-matched (±1 yr) controls without osteoporosis or a history of osteoporotic fracture (n = 43). We measured postprandial plasma levels of glucagon-like peptide 1, glucagon-like peptide 2, and dipeptidyl-peptidase 4 activity, bone mineral density, and baseline levels of bone remodeling markers and analyzed the food intake using a food-frequency questionnaire. Postprandial glucagon-like peptide 1 values were lower (p < 0.001) in cases, µ (SEM) = 116.25 (2.68), than in controls, µ (SEM) = 126.79 (2.68). Glucagon-like peptide 1 was associated with reduced osteoporosis risk in the crude logistic regression analysis [OR (95% CI) = 0.724 (0.53-0.97), p = 0.031] and adjusted analysis [OR = 0.603 (0.38-0.94), p = 0.027]. We found no association of glucagon-like peptide 2, or dipeptidyl-peptidase 4 activity with osteoporosis. Postprandial glucagon-like peptide 1 levels are related to osteoporosis and osteoporosis risk in non-diabetic postmenopausal women. Further studies are required to verify these findings.

Oral and dental health status in patients with eating disorders in Madrid, Spain

Background: The aim of the present study was to describe and compare the oral and dental health status of two groups, one diagnosed with eating disorders (EDs), and another group without this pathology, assessing the fol-lowing oral manifestations: dental alterations, periodontal disorders, soft tissue disorders, non-stimulated salivary flow, and oral pH. Material and Methods: This comparative transversal epidemiological study included 179 participants, of whom 59 were diagnosed with EDs (Eating Disorder Group: EDG) and 120 had no antecedents of EDs (No Eating Disor-der Group: NEDG). All patients fulfilled the following inclusion criteria: women aged over 18 years, diagnosed with an ED by a specialist, patients who had undergone at least 1 year monitoring by the Clinical Nutrition Unit, and had not received any periodontal treatment during the previous 6 months. Both groups were homogeneous in terms of sex, age, education, and socioeconomic level. Oral exploration was performed, registering clinical variables, as well as sociodemographic and socioeconomic data, oral hygiene habits, and smoking. Statistical significance was established as p<0.05 (confidence level > 95%).Results: The dental erosion (DE) was the most significative feature of dental alterations. The degree of DE was significantly greater in the EDG (p<0.001). A significant association between soft tissue lesions and EDs was found (p<0.001) A notable difference in non-stimulated salivary flow was found between the groups (p<0.001) No significant differences between the groups were found for periodontal status, dental caries, or oral hygiene prac-tices. Conclusions: On the basis of the results obtained, it is necessary to carry out oral/dental examination as soon as an ED is diagnosed with regular check-ups thereafter

Lactobacillus reuteri V3401 Reduces Inflammatory Biomarkers and Modifies the Gastrointestinal Microbiome in Adults with Metabolic Syndrome: The PROSIR Study.

Previous studies have reported that probiotics may improve clinical and inflammatory parameters in patients with obesity and metabolic syndrome (MetS). Lactobacillus (L.) reuteri V3401 has shown promising results on the components of MetS in animal studies. We aimed to evaluate the effects of L. reuteri V3401 together with healthy lifestyle recommendations on adult patients with MetS. METHODS: We carried out a randomized, crossover, placebo-controlled, single-center trial in which we included 53 adult patients newly diagnosed with MetS. Patients were block randomly allocated by body mass index (BMI) and sex to receive a capsule containing either the probiotic L. reuteri V3401 (5 × 109 colony-forming units) or a placebo once daily for 12 weeks. Anthropometric variables, biochemical and inflammatory biomarkers, as well as the gastrointestinal microbiome composition were determined. RESULTS: There were no differences between groups in the clinical characteristics of MetS. However, we found that interleukin-6 (IL-6) and soluble vascular cell adhesion molecule 1 (sVCAM-1) diminished by effect of the treatment with L. reuteri V3401. Analysis of the gastrointestinal microbiome revealed a rise in the proportion of Verrucomicrobia. CONCLUSIONS: Consumption of L. reuteri V3401 improved selected inflammatory parameters and modified the gastrointestinal microbiome. Further studies are needed to ascertain additional beneficial effects of other probiotic strains in MetS as well as the mechanisms by which such effects are exerted.

Evaluation of the effect of Lactobacillus reuteri V3401 on biomarkers of inflammation, cardiovascular risk and liver steatosis in obese adults with metabolic syndrome: a randomized clinical trial (PROSIR).

BACKGROUND: Obesity is characterized by increased fat mass and is associated with the development of insulin resistance syndrome (IRS), usually known as metabolic syndrome. The alteration of the intestinal microbiota composition has a role in the development of IRS associated with obesity, and probiotics, which are live microorganisms that confer a health benefit to the host, contribute to restore intestinal microbiota homeostasis and lower peripheral tissue insulin resistance. We aim to evaluate the effects of the probiotic strain Lactobacillus reuteri (L. reuteri) V3401 on the composition of intestinal microbiota, markers of insulin resistance and biomarkers of inflammation, cardiovascular risk, and hepatic steatosis in patients with overweight and obesity exhibiting IRS. METHODS/DESIGN: We describe a randomized, double-blind, crossover, placebo-controlled, and single-centre trial. Sixty participants (aged 18 to 65 years) diagnosed with IRS will be randomized in a 1:1 ratio to receive either a daily dose of placebo or 5 × 109 colony-forming units of L. reuteri V3401. The study will consist of two intervention periods of 12 weeks separated by a washout period of 6 weeks and preceded by another washout period of 2 weeks. The primary outcome will be the change in plasma lipopolysaccharide (LPS) levels at 12 weeks. Secondary outcomes will include anthropometric parameters, lipid profile, glucose metabolism, microbiota composition, hepatic steatosis, and inflammatory and cardiovascular biomarkers. Blood and stool samples will be collected at baseline, at the midpoint (only stool samples) and immediately after each intervention period. Luminex technology will be used to measure interleukins. For statistical analysis, a mixed ANOVA model will be employed to calculate changes in the outcome variables. DISCUSSION: This is the first time that L. reuteri V3401 will be evaluated in patients with IRS. Therefore, this study will provide valuable scientific information about the effects of this strain in metabolic syndrome patients. TRIAL REGISTRATION: The trial has been retrospectively registered in ClinicalTrials.gov on the 23rd November 2016 (ID: NCT02972567 ), during the recruitment phase.

OBJECTIVE: To communicate HPN data obtained from the HPN registry of the NADYA-SENPE group (www.nadya-senpe.com) for the year 2016. MATERIAL AND METHODS: Descriptive analysis of the data collected from adult and pediatric patients with HPN in the NADYA-SENPE group registry from January 1st, 2016 to December 31st, 2016. RESULTS: There were 286 patients from 42 Spanish hospitals (54.2% women), 34 children and 252 adults, with 294 episodes, which represent a prevalence rate of 6.16 patients / million inhabitants / year 2016. The most frequent diagnosis in adults was "palliative cancer" (25.8%), followed by "others". In children it was "motility alterations" with 6 cases (17.6%), Hirschsprung's disease and necrotising enterocolitis, both with 5 children (14.7%). The first indication was short bowel syndrome in both children (64.7%) and adults (37.3%), followed by intestinal obstruction in 28.6% adults and 14.7% in children. The most frequently used type of catheter was tunnelled in both children (70.6%) and adults (37.9%). The most frequent complication in adults was infection related to the catheter, which presented a rate of 0.48 infections / 1,000 days of NPD. During this period, 71 episodes ended in adults and the main cause was death (57.7%) followed by resuming the oral route (31%). CONCLUSIONS: There is a progressive increase of centers and professional collaborators in the registry who report patients receiving parenteral nutrition at home. The main indications of HPN and the motive for ending have remained stable.

Definición de los rangos de referencia de T4 libre, TSH y tiroglobulina en sujetos sanos del Distrito Sanitario de Jaén / Definition of reference ranges for free T4, TSH, and thyroglobulin levels in healthy subjects of the Jaén Health District

Antecedentes y objetivos: Las guías de tratamiento de disfunción tiroidea recomiendan definir los intervalos de referencia de las hormonas tiroideas de cada área mediante la evaluación de datos de población local considerando el grado de nutrición yódica de la misma. El objetivo de este estudio fue definir los rangos de referencia de la tiroxina libre (T4L), TSH y tiroglobulina en población general de Jaén, área con un nivel de nutrición yódica adecuado, y si estos estaban afectados por la yoduria. Material y métodos: Estudio descriptivo transversal realizado en 1.003 sujetos de población general en el Distrito Sanitario de Jaén. El yodo urinario, T4L, TSH, tiroglobulina y los anticuerpos antitiroperoxidasa (anti-TPO) fueron analizados en función de la edad y el sexo. Resultados: La mediana de yoduria fue 110,59μg/l y la media 130,11μg/l. La mediana de TSH fue 1,83μUI/ml (p2,5=0,56μUI/ml, p97,5=4,66μUI/ml). La mediana de T4L fue 0,84ng/dl (p2,5=0,62ng/dl, p97,5=1,18ng/dl). El 5,7% de los sujetos tenían anticuerpos anti-TPO positivos. No existía correlación entre los valores de T4L, TSH ni los anticuerpos anti-TPO con los niveles de yoduria. Los sujetos con anticuerpos anti-TPO positivos tenían una TSH más elevada (3,34μUI/ml frente 2,14μUI/ml; p=0,001; odds ratio=2,42). Conclusiones: El yodo urinario en Jaén está dentro de los valores recomendados por la Organización Mundial de la Salud. Los rangos de referencia de T4L, TSH y tiroglobulina no son diferentes a lo descrito en la literatura y no difieren según la yoduria. La prevalencia de anticuerpos anti-TPO positivos es semejante a la descrita en otras poblaciones de España (AU)

Background and objectives: The treatment guidelines for thyroid dysfunction recommend defining reference ranges for thyroid hormones in each area through assessment of local population data considering the iodine nutritional status. The aim of this study was to define the reference ranges of free thyroxine (FT4), TSH, and thyroglobulin levels in a general population from Jaen, an area of southern Spain with an adequate iodine nutritional status, and whether they were associated with urinary iodine levels. Patients and methods: A cross-sectional study was conducted in 1,003 subjects of the general population of the Jaen Health District. Levels of urinary iodine, FT4, TSH, thyroglobulin, and thyroid peroxidase (TPO) antibodies were measured according to age and sex. Results: Median and mean urinary iodine levels were 110.59μg/L and 130.11μg/L respectively. Median TSH level was 1.83μIU/mL (p2.5=0.56μIU/mL, p97.5=4.66μIU/mL). Median FT4 level was 0.84ng/dL (p2.5=0.62ng/dL, p97.5=1.18ng/dL). TPO antibodies were detected in 5.7% of subjects. There was no correlation between urinary iodine levels and FT4, TSH or TPO antibodies. Subjects with positive TPO antibodies had higher TSH levels (3.34μIU/L versus 2.14μIU/mL, P=.001; odds ratio=2.42). Conclusions: Urinary iodine levels in Jaen are optimal according to World Health Organization standards. Reference ranges of FT4, TSH, and thyroglobulin do not differ from those reported in the literature and are no associated to urinary iodine levels. The prevalence of positive TPO antibodies was similar to that reported in other Spanish areas (AU)

Protein intake and fracture risk in elderly people: a case-control study.

BACKGROUND & AIMS: We investigated whether protein intake (PI) is related to osteoporotic fractures (OP) in the elderly by analyzing vegetable protein intake (VPI), animal protein intake (API), and animal/vegetable protein intake ratio (AVR) and by calcium intake (CaI). METHODS: A 1:1 matched by age and sex case-control study with 167 cases was carried out at the Hospital of Jaen (Spain). Cases were patients aged ≥65 years with a low-energy fracture. Controls were people without previous fractures. Diet was assessed by a food frequency questionnaire. Multivariable analyses were fitted using analysis of covariance (for comparison of adjusted means) and conditional logistic regression (estimating adjusted odds ratios [ORs]). RESULTS: The control-group showed a higher API (p = 0.046) even when CaI was <800 mg/day (p = 0.041). ORs for AVR were 0.68 (0.38-1.19) and 0.38 (0.15-0.98), respectively with a p for trend = 0.046. A PI<15% of the total energy intake showed an OR of 2.86 (1.10-7.43). CONCLUSIONS: Patients with fracture history have lower API suggesting that high API reduce the occurrence of OP in elderly even if CaI is <800 mg/day. A PI<15% of total calories were associated with an increased risk of OP in elderly.
