RESUMO

BACKGROUND: Milk products fortified with vitamin D may constitute an alternative to pharmacological supplements for reaching the optimal levels of serum 25-hydroxyvitamin D [25(OH)D]. Our aim was to analyze the response of serum 25(OH)D and its predictive factors in postmenopausal healthy women after a dietary intervention with a milk fortified with vitamin D and calcium. METHODS: We designed a prospective study including 305 healthy postmenopausal women who consumed a fortified milk with calcium (900 mg/500 mL) and vitamin D3 (600 IU/500 mL) daily for 24 months. RESULTS: The 25(OH)D concentrations at 24 months were correlated to weight, to body mass index, to the percentage of fat, triglycerides and to baseline 25(OH)D levels. We found significant differences in the levels of 25(OH)D at 24 months according to baseline 25(OH)D levels (p < 0.001) and body mass index (p = 0.019) expressed at quartiles. Multivariate analysis showed an association between levels of 25(OH)D after the intervention and at baseline 25(OH)D (Beta = 0.47, p < 0.001) and percentage of body fat (Beta = -0.227, p = 0.049), regardless of the body mass index. CONCLUSIONS: In healthy postmenopausal women, the improvement in 25(OH)D after an intervention with a fortified milk for 24 months depends mainly on the baseline levels of serum 25(OH)D and on the percentage of body fat.

RESUMO

Objetivo: El tratamiento de la diabetes tipo 2 (DM2) es complejo y su propósito es reducir la morbimortalidad, por lo que su manejo tiene que incluir: un control glucémico individualizado precoz (mediante una adecuada educación diabetológica, modificaciones del estilo de vida y tratamiento farmacológico), el control de los factores de riesgo cardiovascular (CV), la detección y tratamiento precoz de las complicaciones y la evaluación de las comorbilidades asociadas. El objetivo fue elaborar un documento para unificar los aspectos necesarios para el abordaje integral de las personas con DM2. Participantes: Miembros del Grupo de trabajo de Diabetes Mellitus de la Sociedad Española de Endocrinología y Nutrición. Métodos: Se realizó una revisión de la evidencia disponible relativa a cada aspecto del manejo de la diabetes: objetivos de control glucémico, dieta y ejercicio, tratamiento farmacológico, tratamiento y control de factores de riesgo, detección de complicaciones y manejo del paciente frágil con DM2. Las recomendaciones se formularon según los grados de evidencia recogidos en los Standards of Medical Care in Diabetes 2018. Tras la formulación de las recomendaciones el documento fue consensuado por los miembros del Grupo de trabajo de Diabetes Mellitus de la Sociedad Española de Endocrinología y Nutrición. Conclusiones: El objetivo de este documento es proporcionar, desde el punto de vista del endocrinólogo clínico, unas recomendaciones prácticas basadas en la evidencia acerca de todos los aspectos necesarios para el abordaje integral de la DM2

RESUMO

AIMS: To analyze the trends on diabetes mellitus (DM) healthcare management in Spain. METHODS: Retrospective observational study between January 1st 2007 and 31th December 2015 with DM as the principal diagnosis. The main clinical outcome measures were all-cause, in-hospital mortality and 30-day readmissions. We also analyze three Prevention Quality Indicators (PQI) for DM. RESULTS: The number of hospitalization episodes decreased significantly as well as the frequentation rate and average length of stay (Incidence Rate Ratio [IRR] = 0.963, p < 0.001; 0.91, p < 0.001 and 0.986, p < 0.001, respectively). Crude in-hospital mortality and readmissions rates and risk-standardized in-hospital mortality rates (RSMR), however, remained stable (IRR = 0.988, p = 0.073; IRR = 1.003, p = 0.334 and IRR = 0.997, p = 0.116, respectively). A relevant variability in RSMR, both at hospital (Median Odds Ratio 1.49) and regional level, was found. High volume hospitals (≥105 DM discharges at year) showed better outcomes. High variability was also found in PQI indicators al regional level. CONCLUSION: The present analysis shows an improvement in hospitalizations related to DM in Spain in the period 2007-2015. There was also a decrease in the frequentation rate and in the average length of stay. These findings are probably explained by quality improvements in the healthcare management of the DM at the ambulatory level. However, there were important differences in the management of diabetic inpatients both at the hospital and the regional level.

RESUMO

OBJECTIVE: The aim of this study is to develop guidance on the use of intravitreal dexamethasone implants in the treatment of diabetic macular edema. METHOD: The study was performed using the modified Delphi method to obtain a consensus among a panel of experts on management of patients with diabetic macular edema and use of intravitreal dexamethasone implants in clinical practice. Thirty-seven panel members, experts on retina, from different Spanish centers were invited to participate. Individual and anonymous opinions were asked by answering a 76-item questionnaire across 11 topic areas (two rounds were done). Level of agreement was assessed using a Likert-type scale of 9 points. RESULTS: Agreement on "consensus" was reached during the first round in 63 items. The 13 remaining items underwent a second round of voting. After the second round, agreement on "consensus" was reached on five items. Finally, eight items remained without consensus. CONCLUSION: Intravitreal dexamethasone implants are useful in the treatment of patients with diabetic macular edema with different profiles, for example, pseudophakic, poor-adherents, vitrectomized, candidates for cataract surgery, patients with high inflammatory component, and with a history of cardiovascular events. The use of intravitreal dexamethasone reduces the number of visits and facilitates compliance. Experts thought that the switch from anti-vascular endothelial growth factor therapy to intravitreal dexamethasone implants should be done preferably after three injections. Also, pro re nata treatment provides better results in diabetic macular edema patients as it helps to prevent undertreatment. Finally, experts concluded that clinical guidelines and treatment protocols for diabetic macular edema need to be updated.

RESUMO

BACKGROUND: Postmenopausal osteoporosis (PMO) is associated with other comorbidities such as impaired glucose homeostasis and cardiovascular disease. Vitamin D insufficiency is highly prevalent and may be a common link between these disorders. However, the relationship between circulating 25-hydroxyvitamin D [25(OH)D] and insulin resistance in women with PMO has not been well evaluated. The aim of this study was to assess the relationship between circulating levels of 25(OH)D and parameters of glucose homeostasis in a cohort of women with PMO to establish a serum concentration threshold of 25(OH)D for improved glycemic parameters. MATERIALS AND METHODS: This cross-sectional study included 40 women with PMO. We measured 25(OH)D serum levels and glucose homeostasis parameters (glucose and insulin levels, insulin sensitivity, and ß-secretion index HOMA2-%S and HOMA2-%B, respectively). Anthropometric, biochemical, and clinical parameters and bone markers were also evaluated. RESULTS: Circulating levels of 25(OH)D were related to glucose parameters (negatively with HOMA2-%B and insulin levels and positively with HOMA2-%S) in women with PMO, resulting in an indicator of insulin sensitivity independent of age, body mass index, percent body fat, and undercarboxylated osteocalcin. Patients with serum 25(OH)D ≥45 ng/mL showed lower HOMA2-%B values and insulinemia and greater HOMA2-%S. CONCLUSIONS: Our results support the hypothesis that circulating 25(OH)D levels are related to improved glucose homeostasis in women with PMO. However, this relationship was apparent only in the presence of high circulating levels of 25(OH)D.

RESUMO

OBJECTIVE: HIV infection is associated with an increased risk of cardiovascular disease. Irisin is a miokyne secreted by skeletal muscle, which may influence insulin homeostasis, nonalcoholic fatty liver disease (NAFLD) and atherosclerosis. Our objective was to evaluate the relationships between serum irisin, insulin homeostasis, NAFLD and subclinical atherosclerosis in HIV-infected males. DESIGN: Cross-sectional study in a cohort of HIV-infected patients. PATIENTS: Inclusion criteria: men older than 18 years; antiretroviral therapy (ART) -naïve or on effective ART (<50 HIV-1 RNA copies/mL) without changes in the previous 6 months; no diabetes or hepatitis C. MEASUREMENTS: Irisin was measured by enzymatic immunoassay (Phoenix Pharmaceuticals), insulin sensitivity by homeostasis model assessment of insulin resistance (HOMA-IR), as well as the 2-hour continuous infusion of glucose with model assessment (CIGMA-HOMA). Hepatic steatosis was measured by 1-H magnetic resonance spectroscopy, subclinical atherosclerosis by evaluation of carotid intima-media thickness (C-IMT), measured by Ultrasonography. RESULTS: Eight nine men (age 42.0 ± 8.3 years, duration of HIV infection 7.9 ± 5.6 years, CD4 count 547 ± 279 cells/mL) were included. Circulating irisin was positively related to HOMA-IR and CIGMA-HOMA, hepatic triglyceride content, and to VAT/SAT ratio. Higher irisin concentrations were associated with higher C-IMT, although this association did not persist in multivariate analysis. Lipodystrophy and a higher baseline PAI-1 concentration were independently associated with C-IMT. CONCLUSIONS: In male HIV patients without diabetes, higher irisin concentrations are positively associated with insulin resistance, NAFLD and subclinical atherosclerosis. However, waist-hip-ratio is the main determinant of insulin resistance, and PAI-1 and lipodystrophy were the strongest determinants of IMT in this population.

RESUMO

OBJECTIVE: To determine the effect of the daily intake of calcium and vitamin D-enriched milk (with or without fructooligosaccharides [FOS]) on vitamin D, bone metabolism, and cardiovascular risk factors. MATERIALS AND METHODS: Two-year randomized controlled study, including 500 healthy postmenopausal women, assigned to 500 mL/day of skimmed milk to one of three groups: Low-dose (L): (120 mg/100 mL calcium, vitamin D3 30 UI/100 mL), group A: calcium and vitamin D (180 mg/100 mL and 120 UI/100 mL), and group B: calcium and vitamin D (180 mg/100 mL and 120 UI/100 mL) and FOS (5 g/L). We evaluated serum 25(OH)D, bone mineral density (BMD) by Dual Energy X-ray Absorptiometry, and biochemical data of glucose and lipid metabolism. RESULTS: After 24 months, vitamin D concentrations did not change in the control group, but increased in group A and group B, p < 0.001. We observed an increase in femoral neck BMD and an improvement in fasting plasma glucose, HbA1c, total cholesterol, low-density lipoprotein cholesterol, and apolipoprotein B 100. CONCLUSIONS: Daily intake of milk enriched with calcium and vitamin D in postmenopausal healthy women induces a significant improvement in vitamin D status, a significant increase in BMD at femoral neck, and also favorable effects on glucose and lipid profile.

RESUMO

The relationship between glycaemia, arrhythmia and changes in electrocardiogram (ECG) has been addressed showing mixed results. The objective of this study was to evaluate the changes in ECG, evaluated by Holter monitoring, induced by clinical hypoglycaemia in patients with type 1 diabetes (T1DM) and type 2 diabetes (T2DM), aged 50 or older, with high cardiovascular risk. Five-lead Holter monitoring (BL-900 Braemar, Inc, Norav Medical NH301-2.4.5 software), and blinded interstitial continuous glucose monitoring (CGM) (Dexcom G4-Platinum, range 40-400 mg/dl) was performed with time synchronization. In the Holter registry, in patients with hypoglycemic episodes, mean QTc during hypoglycaemia was longer compared to mean QTc in total group (+4.6 ms, p = 0.037) and T1DM patients (+5.5 ms, p = 0.048) but not in T2DM patients (+3 ms, p = 0.459). During hypoglycaemia, non-clinical significant disturbances in heart rhythm were observed. In conclusion, we observed a prolongation in QTc during hypoglycemia, mainly in T1DM. However, our study does not show a relationship between episodes of hypoglycaemia and clinical arrhythmias, at least in T1DM and T2DM patients with high cardiovascular risk.

RESUMO

OBJECTIVE: Nutritional strategies can be effective for the prevention of menopause-related diseases, such as osteoporosis and cardiovascular disease. Our aim was to evaluate the effects of a dairy product enriched in polyunsaturated fatty acids, calcium, oleic acid, and vitamins on cardiovascular markers and bone metabolism in postmenopausal women with moderate cardiovascular risk. METHODS: One hundred seventeen healthy postmenopausal women (aged 45 ± 7.7 years) were allocated to 2 groups: the intervention group (IG; n = 63), who consumed 0.5 L/day of a low-lactose skimmed milk enriched with 40 mg/100 mL of eicosapentaenoic acid (EPA) + docosahexaenoic acid (DHA), 0.54 g/100 mL oleic acid, and vitamins, and the control group (CG; n = 54), who consumed 0.5 L/day of semiskimmed milk 0.5 L/day enriched with vitamins A and D. RESULTS: After 12 months, in the IG there was an improvement in lipid profile: a -5.78% decrease in total cholesterol (p = 0.010), -9.79% (p = 0.004) in low-density lipoprotein (LDL) cholesterol, -9.56% (p < 0.001) in total cholesterol (TC)/high-density lipoprotein (HDL) ratio, and -3.38% in LDL/HDL ratio (p < 0.001). No changes were observed in the CG. In the IG we observed a decrease of -28.20% in high-sensitivity C-reactive protein (hs-CRP; p = 0.012). There was no effect on bone turnover markers or serum osteoprotegerin (OPG) in either of the study groups. In the IG, receptor activator of nuclear factor κB ligand (RANKL) was reduced -17.64% (p = 0.003), with no effect in the CG. CONCLUSION: In postmenopausal women with moderate cardiovascular risk, dietary supplementation with a dairy drink enriched with fatty acids (EPA+DHA), oleic acid, minerals, and vitamins induces a positive effect on cardiovascular risk and parameters of bone metabolism. Its regular consumption may be a useful nutritional support for postmenopausal women.

RESUMO

Myostatin and irisin are two myokines related to energy metabolism, acting on skeletal muscle and recently suggested on adipose tissue in mice. However, the exact role of these myokines in humans has not been fully established. Our aim was to evaluate the relationship between serum levels of myostatin and irisin in type 2 diabetes mellitus patients and non-diabetic controls and to explore its links with metabolic parameters. Case-control study including 73 type 2 diabetes mellitus patients and 55 non-diabetic subjects as control group. Circulating myostatin and irisin levels were measured by enzyme-linked immunosorbent assays. Type 2 diabetes mellitus patients showed significantly lower myostatin levels (p = 0.001) and higher irisin levels (p = 0.036) than controls. An inverse relationship was observed between myostatin and irisin levels (p = 0.002). Moreover, in type 2 diabetes mellitus patients, after adjusting by confounder factors, myostatin was negatively related to fasting plasma glucose (p = 0.005) and to triglyceride levels (p = 0.028) while irisin showed a positive association with these variables (p = 0.017 and p = 0.006 respectively). A linear regression analysis showed that irisin and fasting plasma glucose levels were independently associated to myostatin levels and that myostatin and triglyceride levels were independently associated to irisin concentrations in type 2 diabetes mellitus patients. Our results suggest that serum levels of myostatin and irisin are related in patients with type 2 diabetes. Triglyceride and glucose levels could modulate myostatin and irisin concentrations as a compensatory mechanism to improve the metabolic state in these patients although further studies are needed to elucidate whether the action of these myokines represents an adaptative response.

RESUMO

INTRODUCTION: The biological mechanisms associated with an inadequate response to treatment with bisphosphonates are not well known. This study investigates the association between circulating levels of sclerostin and estradiol with an inadequate clinical outcome to bisphosphonate therapy in women with postmenopausal osteoporosis. METHODS: This case-control study is based on 120 Spanish women with postmenopausal osteoporosis being treated with oral bisphosphonates. Patients were classified as adequate responders (ARs, n=66, mean age 68.2±8 years) without incident fractures during 5 years of treatment, or inadequate responders (IRs, n=54, mean age 67±9 years), with incident fractures between 1 and 5 years of treatment. Bone mineral density (DXA), structural analysis of the proximal femur and structural/fractal analysis of the distal radius were assessed. Sclerostin concentrations were measured by ELISA and 17ß-estradiol levels by radioimmunoassay based on ultrasensitive methods. RESULTS: In the ARs group, sclerostin serum levels were significantly lower (p=0.02) and estradiol concentrations significantly higher (p=0.023) than in the IRs group. A logistic regression analysis was performed, including as independent variables in the original model femoral fracture load, 25 hydroxyvitamin D, previus history of fragility fracture, sclerostin and estradiol. Only previous history of fragility fracture (OR 14.04, 95% CI 2.38-82.79, p=0.004) and sclerostin levels (OR 1.11, 95% CI 1.02-1.20, p=0.011), both adjusted by estradiol levels remained associated with IRs. Also, sclerostin concentrations were associated with the index of resistance to compression (IRC) in the fractal analysis of the distal radius, a parameter on bone microstructure.
