Daily phytate intake increases adiponectin levels among patients with diabetes type 2: a randomized crossover trial.

AIM: Adiponectin, a major adipokine secreted by adipose tissue, has been shown to improve insulin sensitivity. Myo-inositol hexaphosphate (phytate; InsP6) is a natural compound that is abundant in cereals, legumes, and nuts that has demonstrated to have different beneficial properties in patients with diabetes type 2. METHODS: We performed a randomized crossover trial to investigate the impact of daily consumption of InsP6 on serum levels of adiponectin, TNF-alpha, IL-6, and IL-1beta in patients with type 2 diabetes mellitus (T2DM; n = 39). Thus, we measure serum levels of these inflammatory markers, classic vascular risk factors, and urinary InsP6 at baseline and at the end of the intervention period. RESULTS: Patients who consumed InsP6 supplements for 3 months had higher levels of adiponectin and lower HbA1c than those who did not consume InsP6. No differences were found in TNF-alpha, IL-6, and IL-1beta. CONCLUSION: This is the first report to show that consumption of InsP6 increases plasma adiponectin concentration in patients with T2DM. Consequently, our findings indicate that following a phytate-rich diet has beneficial effects on adiponectin and HbA1c concentrations and it could help to prevent or minimize diabetic-related complications.

The effects of chronic back pain on self-management, clinical and psychological outcomes among patients with type 2 diabetes.

BACKGROUND: Chronic back pain (CBP) in patients with type 2 diabetes (T2DM) is twice as high among age-and-gender-matched controls. The presence of both conditions impacts negatively on both quality of life and physical function, which might negatively affect mood. METHODS: We aimed to determine the prevalence of CBP among patients with T2DM by using the Lattinen Index (LI) and to assess whether the presence of CBP had any influence on clinical or psychological outcomes. RESULTS: 13.5% out of 299 patients had significant CBP. The percentage of patients with less than 150 minutes per 1 week of exercise was higher in the group of patients with significant CBP (70% vs 51.4%; p= 0.04). The proportion of patients who met criteria for food addiction was greater among subjects with CBP (47.5% vs 26.6%; p=0.009). The percentage of patients with criteria for depression was higher among the CBP group (82.5% vs 29.7%; p<0.0001), as well as the prescription of antidepressants (45% vs 17.4%; p<0.0001). However, no significant differences were seen regarding glycemic control or the frequency of complications related to T2DM. CONCLUSIONS: CBP is prevalent among subjects with T2DM and it constitutes an important limiting factor of both self-care behaviors and psychological well-being.

Long-Term Prevalence of Food Addiction Among Bariatric Surgery Patients: Influence on Metabolic and Psychological Outcomes.

Background: We wanted to assess the prevalence of individuals with food addiction (FA) among bariatric surgery (BS) patients at long term and to determine if there was any relationship between FA and both clinical and psychological outcomes at the time of the evaluation. Methods: Participants were evaluated for the presence of FA with the Yale Food Addiction Scale 2.0. Results: Of 134 subjects, 32 (23.9%) included met criteria for FA. The frequency of patients with depression at the time of the evaluation was greater among subjects with FA (34.4% vs. 11.8%; P = 0.006). The score obtained with the Beck Depression Inventory at the time of the evaluation was greater among subjects with FA (14.8 ± 11.5 vs. 6 ± 6.5; P < 0.0001). The frequency of subjects with FA who had criteria for binge eating disorder at the time of the evaluation was significantly greater (56.3% vs. 20.5%; P < 0.001). Patients with FA scored higher in the Lattinen index for chronic pain at the time of the evaluation (8.7 ± 5.9 vs. 5.8 ± 5.4; P = 0.014). However, clinical outcomes were similar between the two groups. Conclusions: Routine screening for FA at long term postoperatively should be recommended to improve psychological outcomes of BS.

Role of Advanced Glycation End Products on Aortic Calcification in Patients with Type 2 Diabetes Mellitus.

The aim of this study was to evaluate the relationship between serum levels of advanced glycation end products (AGEs) and abdominal aortic calcification (AAC) in patients with type 2 diabetes mellitus (DM2). This was a prospective cross-sectional study. One-hundred and four consecutive patients with DM2 were given lateral lumbar X-rays in order to quantify abdominal aortic calcification (AAC). Circulating levels of AGEs and classical cardiovascular risk factors were determined. Clinical history was also registered. Patients with higher AGEs values had higher grades of aortic calcification and higher numbers of diabetic-related complications. Multivariate logistic regression analysis showed that being older, male and having high levels of AGEs and triglycerides were the independent risk factors associated to moderate-severe AAC when compared to no-mild AAC. Our results suggest that AGEs plays a role in the pathogenesis of aortic calcifications. In addition, the measurement of AGEs levels may be useful for assessing the severity of AAC in the setting of diabetic complications.

Associations of food addiction with metabolic control, medical complications and depression among patients with type 2 diabetes.

AIMS: Food addiction (FA) is conceptualized as a behavioral pattern that is similar in some ways to addictions to alcohol and other substances. This disorder has not been well studied among patients with type 2 diabetes (T2DM). We aimed to analyze if there is any relationship between FA and clinical or psychological variables among patients with T2DM. METHODS: Three hundred patients with T2DM were analyzed cross-sectionally. Participants were evaluated for the presence of FA by completing the Yale Food Addiction Scale 2.0 questionnaire. RESULTS: 29.3% of patients screened positive for FA. Patients with FA had a greater BMI (33.41 ± 7.5 vs. 31.6 ± 5.9 kg/m2; p = 0.04). HbA1c was higher among individuals with FA (7.9 ± 4.4 vs. 7.6 ± 1.4%, p = 0.008). The proportion of subjects with diabetic retinopathy, neuropathy and nephropathy was greater among patients with criteria for FA compared with patients without this condition (25% vs. 13.2%, 29.5% vs. 21.8% and 32% vs. 22.3%; p = 0.03, p = 0.05 and p = 0.05, respectively). The percentage of patients with FA with significant depressive symptoms was also greater (36.4% vs. 18.5%; p = 0.002). CONCLUSIONS: The presence of FA among T2DM patients implied a worse glycaemic control. Microvascular complications and depressive symptoms were higher among these patients.

A Pilot Randomized Crossover Trial Assessing the Safety and Short-Term Effects of Walnut Consumption by Patients with Chronic Kidney Disease.

The aim of this study of patients with chronic kidney disease (CKD) is to assess the safety of daily consumption of walnuts on the physiological levels of phosphorous, potassium, parathyroid hormone (PTH), and fibroblast growth factor 23 (FGF23), and to assess the short-term benefits of this intervention on risk factors associated with cardiovascular events. This led us to perform a prospective, randomized, crossover, pilot clinical trial examined 13 patients with CKD. Subjects were randomly assigned to a diet of 30 g of walnuts per day or the control diet. After 30 days, each group was given a 30-day washout period, and then switched to the alternate diet for 30 days. Urinary and serum levels of phosphorous and potassium, multiple vascular risk factors, and urinary inositol phosphates (InsPs) were measured at baseline and at the end of the intervention period. Our results showed that the walnut dietary supplement led to reduced blood pressure, LDL cholesterol, and albumin excretion, but had no effect on the physiological levels of phosphorous, potassium, PTH, and FGF23. This is the first report to show that daily consumption of walnuts by patients with CKD does not alter their physiological levels of phosphorous, potassium, PTH, and FGF23 when included in a sodium-, protein-, phosphate-, and potassium-controlled diet, and it could be an effective strategy for reducing cardiovascular risk in patients with CKD.

Phytate Decreases Formation of Advanced Glycation End-Products in Patients with Type II Diabetes: Randomized Crossover Trial.

Myo-inositol hexaphosphate (phytate; IP6) is a natural compound that is abundant in cereals, legumes, and nuts and it has the ability to chelate metal cations. The binding of IP6 to transition metals suggests that it could be used for the treatment of metal-catalyzed protein glycation, which appears to trigger diabetes-related diseases. Our in vitro studies showed that IP6 reduced the formation of Fe3+-catalyzed advanced glycation end-products (AGEs). This led us to perform a randomized cross-over trial to investigate the impact of the daily consumption IP6 on protein glycation in patients with type 2 diabetes mellitus (T2DM; n = 33). Thus, we measured AGEs, glycated hemoglobin (HbA1c), several vascular risk factors, and urinary IP6 at baseline and at the end of the intervention period. Patients who consumed IP6 supplements for 3 months had lower levels of circulating AGEs and HbA1c than those who did not consume IP6. This is the first report to show that consumption of IP6 inhibits protein glycation in patients with T2DM. Considering that AGEs contribute to microvascular and macrovascular complications in T2DM, our data indicates that dietary supplementation with IP6 should be considered as a therapy to prevent the formation of AGEs and therefore, the development of diabetes-related diseases in patients with T2DM.

Effects of depressive symptoms on clinical outcomes, inflammatory markers and quality of life after a significant weight loss in a bariatric surgery sample.

INTRODUCTION: Obesity is linked to a low-grade chronic systemic inflammation that improves after weight loss. Depressive disorder has been suggested to be associated with systemic inflammation up regulation. OBJECTIVE: We aimed to explore whether, after a significant weight loss, the presence of depressive symptoms was associated with differences in terms of inflammatory markers and quality of life. METHODS: Sixty patients (78.3%♀, age 46.4 ± 9.9) who underwent bariatric surgery, with a minimum follow up of 18 months, were evaluated. For the screening of depression, the Beck Depression Inventory (BDI) was administered. RESULTS: Ten subjects (16.6%) had a positive screening for depressive disorder. The percentage of patients with weight regain was greater among subjects with symptoms of depression (70% vs. 32%; p = 0.024), although no differences were seen regarding BMI prior to surgery and current BMI. Acute phase reactants were higher among subjects with symptoms of depression: platelets (319 ± 15 x 10^12/L vs. 232 ± 47 x 10 ^ 12/L; p = 0.001), erythrocyte sedimentation rate (24.7 ± 11.3 mm vs.17 ± 10 mm; p = 0.03), fibrinogen (486 ± 107 mg/dL vs. 406 ± 66 mg/dL; p = 0.003), ferritin (106 ± 180 ng/ml vs. 34 ± 44 ng/ml; p = 0.014) and ultrasensitive C-reactive protein (0.96 ± 1.84 mg/dL vs. 0.24 ± 0.26 mg/dL; p = 0.008). All domains of quality of life were significantly lower in the depressive group. CONCLUSIONS: Despite a significant weight loss, inflammatory markers are greater and quality of life lower when associated with depressive symptoms.

Introducción: la obesidad se asocia a una inflamación crónica de bajo grado que mejora tras la pérdida de peso. El trastorno depresivo también se ha asociado a una inflamación sistémica. Objetivo: determinar si, tras una pérdida de peso significativa, la presencia de síntomas depresivos se asocia a diferencias en los marcadores inflamatorios y la calidad de vida. Métodos: sesenta pacientes (78,3% ♀, edad 46,4 ± 9.9) sometidos a cirugía bariátrica, con un seguimiento mínimo de 18 meses, fueron evaluados. Se autoadministró el test de depresión de Beck (BDI) para el screening de depresión. Resultados: diez sujetos (16,6%) tenían un screening positivo para depresión. El porcentaje de pacientes que ganaron peso fue superior en el grupo de pacientes con síntomas depresivos (70% vs. 32%; p = 0,024), aunque no se evidenciaron diferencias en cuanto al IMC antes de la cirugía ni al IMC actual. Los reactantes de fase aguda fueron mayores entre los sujetos con síntomas depresivos: plaquetas (319 ± 15 x 10

Electro-acupuncture for treatment of knee pain from osteoarthritis and the possible endocrinology changes: a study protocol for a randomized controlled trial.

BACKGROUND: Osteoarthritis of the knee is a major cause of disability among adults. Electro-acupuncture is considered a potentially useful treatment for osteoarthritis. The purpose of this study is to assess the efficacy of electro-acupuncture on pain control, pain perception, plasma cortisol and beta-endorphin levels, patient-perceived quality of life, and pain medication use in patients with chronic knee pain. METHODS/DESIGN: This study is a placebo-controlled, randomized, double-blind, parallel design trial. One hundred sixty out-patients who are more than 50 years old and who have osteoarthritis of the knee will be recruited from the island of Mallorca, Spain. Each participant will be randomly placed into one of two groups: (sham) electro-acupuncture non-insertion technique and real electro-acupuncture. Acupuncture treatments will be the Traditional Chinese Medicine type. The patients will be evaluated after a period of 1 month (with two weekly sessions), 3 months (with one monthly session), 6 months (with one session every 45 days), and 1 year later with follow-up sessions at the end of the study (with one session every 2 months). The primary outcomes will be based on the observed changes from the baseline of the visual analogue scale (VAS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) for pain measured at 12 weeks after the end of treatment. Also to be included in the study are the possible changes in the secondary efficacy variables from baseline as assessed by the Short Form 36 version 2 health survey (patient-perceived quality of life), patient plasma cortisol and beta-endorphin levels at the different treatment stages, the Goldberg Anxiety and Depression Scale, pain medication use, functional capacity and stiffness (WOMAC subscales), and a VAS. These variables will be assessed at 1 month, 3 months, 6 months, and 1 year after study commencement. DISCUSSION: The findings from this study will help to determine whether electro-acupuncture is effective for chronic knee pain management in older people and whether electro-acupuncture can deliver results for the improvement of pain relief, stiffness, and disability. The study will therefore be a major step toward understanding the roles of the hypothalamic-pituitary-adrenal axis and the endogenous opioid system in the effectiveness of electro-acupuncture for chronic pain. TRIAL REGISTRATION: ClinicalTrials.gov identifier NCT02299713 (11 Nov. 2014).

Postoperative grazing as a risk factor for negative outcomes after bariatric surgery.

INTRODUCTION/PURPOSE: After bariatric surgery, de novo eating patterns can develop, such as grazing. Although grazing has been associated with poorer weight loss, it has received minimal attention. We aimed to assess the influence of grazing in clinical, biochemical and psychological outcomes in a bariatric surgery sample. MATERIALS AND METHODS: Sixty patients (78.3%♀, age 46.35±9.89, months since BS 46.28±18.1) who underwent BS were evaluated cross-sectionally. Clinical, biochemical and psychological parameters were recorded. A pattern of grazing was assessed in this group of patients through interview. RESULTS: 41.7% met criteria for grazing. Mean time since BS was greater in the group with grazing (57.64±23.7months vs 38.8±26.44months; p=0.008). Although there were no differences in initial and current BMI, the percentage of patients with weight regain was greater among patients with grazing (72% vs 11.7%; p<0.0001) and the percentage of excess weight loss was lower (28.15±6.96% vs 33.35±11.9%; p=0.05). There were more difficulties in following the standardized visits according to our hospital's protocol (17.6% vs 56%; p=0.009). No significant differences were found when assessing presurgical psychiatric comorbidity among patients with a grazing pattern and individuals without this condition (68% vs 55.9%; p=0.423). When assessing quality of life only mental health was lower among patients with grazing (49.6±22.7 vs 64.2±23.3; p=0.02). CONCLUSION: Development of grazing is frequent after BS, especially when weight loss has reached a plateau. Due to its potential association with weight regain, systematic screening of grazing after BS is warranted.

Eating disorders are frequent among type 2 diabetic patients and are associated with worse metabolic and psychological outcomes: results from a cross-sectional study in primary and secondary care settings.

AIMS: Data regarding the prevalence of eating disorders (ED) and their influence on clinical outcomes among patients with type 2 diabetes (T2DM) are scarce. Our aim is to investigate the frequency of positive screening for ED, specifically binge eating disorder (BED), in a T2DM sample and analyze whether there are any differences among T2DM subjects with a positive screening for ED or BED. METHODS: Three hundred and twenty subjects with T2DM were recruited randomly. All participants were evaluated for the presence of ED by completing the "Eating Attitudes Test-26" (EAT-26). In addition, the "Questionnaire of Eating and Weight Patterns-Revised" (QEWP-R) for the screening of BED was also implemented. Sociodemographic, clinical and biochemical parameters were also recorded. RESULTS: According to EAT-26, 14 % of subjects screened positive for ED. Regarding QEWP-R, 16 % had a positive screening for ED, with BED having a frequency of 12.2 %, being the most prevalent one. There was a positive correlation between the scores obtained with the EAT-26 and the Beck Depression Inventory (p = 0.0014). Patients with BED were younger (57.5 ± 11.1 vs 63.3 ± 10.3 years; p = 0.004), with a lesser T2DM duration (8.5 ± 6.1 vs 12.1 ± 9.6 years; p = 0.002). Weight and BMI among subjects with BED were greater (89.1 ± 1.3 vs 82.4 ± 16.7 kg; p = 0.04 and 39.4 ± 10.3 vs 30.7 ± 5.5 kg/m(2); p = 0.01). The frequency of subjects with one admission related to T2DM or any other condition during the last year was higher (10 vs 3 %; p = 0.04 and 33 vs 21 %; p = 0.01). CONCLUSIONS: ED among T2DM are frequent. Due to their deleterious effect on different metabolic and psychological outcomes, they should be diagnosed promptly, especially BED.

Are subjects with criteria for adult attention-deficit/ hyperactivity disorder doing worse after bariatric surgery? A case-control study / ¿Tienen peores resultados los individuos con criterios para trastorno por déficit de atención/ hiperactividad tras la cirugía bariátrica? Estudio de casos y controles

Introduction: There is an increasing awareness of the strong associations between obesity and adult attention-deficit/hyperactivity disorder (ADHD), with high rates of ADHD (26-61%) in patients seeking weight loss. Aims: To determine the frequency of ADHD in a bariatric surgery (BS) sample and investigate whether there were any differences among clinical, analytical and psychological parameters in individuals with criteria for ADHD. Methods: Sixty patients (78.3% female, age 46.3±9.8, months since BS 46.28±18.1) who underwent BS, with a minimum follow-up of 18 months, were evaluated cross-sectionally. Initial and current BMI, eating patterns, comorbidity, socio-demographic and biochemical parameters were recorded. For the screening of ADHD, ADHD self rating scale-v1.1 was administered. Results: Nineteen individuals (31.6%) had a positive screening for ADHD. This group had higher levels of HDL-cholesterol (62.8±17.3mg/dl vs 53.5±9.9mg/dl; p=0.011) and Apo-A (177.7±28.4mg/dl vs 154.9±34.7mg/ dl; p=0.015), and an increased consumption of lipids (42.2±7.1% vs 36.7±8.3%; p=0.019). Subjects with ADHD symptoms had more difficulties in following visits after BS (52.6% vs 24.3%; p= 0.011).We could not find any differences in achieved BMI, depressive symptoms or quality of life. Conclusions: Patients who met criteria for ADHD face significant difficulties with compliance in follow-up, but we could not find differences in major clinical outcomes. Surprisingly, these patients could have a protective lipid profile (AU)

Introducción: Hay una creciente concienciación de la fuerte asociación entre la obesidad y el trastorno por déficit de atención/hiperactividad del adulto (TDAH), con elevadas tasas de TDAH (26-61%) en los pacientes que consultan por pérdida ponderal. Objetivos: conocer la frecuencia del TDAH en una muestra de sujetos sometidos a cirugía bariátrica (CB) e investigar si existen diferencias clínicas, analíticas y psicológicas en estos sujetos. Métodos: Sesenta pacientes (78.3% mujeres, edad 46.3±9.8, meses desde la CB 46.28±18.1) sometidos a CB, con un seguimiento mínimo desde ésta de 18 meses, fueron evaluados transversalmente. Se recogieron y analizaron el IMC inicial y en el momento de la evaluación, patrones alimentarios, comorbilidades, y parámetros sociodemográficos y bioquímicos. Para el screening del TDAH se administró la versión española del 'ADHD self-rating scale v 1.1'. Resultados: Diecinueve individuos (31.6%) tenían un screening positivo para TDAH. Estos sujetos tenían niveles superiores de HDL colesterol (62.8±17.3mg/dl vs 53.5±9.9mg/dl; p=0.011) y Apo-A (177.7±28.4mg/dl vs 154.9±34.7mg/dl; p=0.015), y un consumo mayor de lípidos en la dieta (42.2±7.1% vs 36.7±8.3%; p=0.019). Estos sujetos tenían más dificultades en seguir las visitas protocolizadas tras la CB (52.6% vs 24.3%; p= 0.011). No se evidenciaron diferencias en el IMC alcanzado, síntomas depresivos o calidad de vida. Conclusiones: Los pacientes sometidos a CB con criterios para TDAH presentan más dificultades en la adherencia al seguimiento, pero no se evidenciaron diferencias en resultados clínicos relevantes. Curiosamente, estos sujetos podrían presentar un perfil lipídico protector (AU)

Cardiovascular risk profile in Mediterranean patients submitted to bariatric surgery and intensive lifestyle intervention: impact of both interventions after 1 year of follow-up.

BACKGROUND: The aim was to compare obesity-related cardiovascular (CV) risk factors (classic and emerging) and the estimated CV risk at 10 years (calculated by REGICOR) in obese Mediterranean patients submitted to bariatric surgery and intensive lifestyle intervention at baseline and after 1 year of follow-up. METHODS: Patients submitted to bariatric surgery (n = 108) and standardized program of therapeutic changes in lifestyle (n = 90) were retrospectively included. Clinical history, physical examination, and laboratory analysis were routinely determined before weight loss intervention and at 1 year follow-up. RESULTS: Seventy-five percent of the surgery patients had a CV risk lower than 5 % and not one patient had a 10-year CV risk higher than 15 %. The percentage of patients with comorbidities (diabetes and sleep apnea syndrome) was higher in the surgery group. Seventeen of the surgery patients had no comorbidities. The improvement in CV risk profile was significant higher in the surgery group. CV risk benefit of both intervention groups was related to baseline higher CV risk, with type 2 diabetes with poor metabolic control and high cholesterol levels being the most important predictors for surgery patients. Neither body mass index nor excess of weight loss was related to CV risk improvement. CONCLUSIONS: Mediterranean patients undergoing a weight loss intervention have a low CV risk. In comparison with lifestyle intervention, surgery induces a better improvement of CV risk. This benefit is related to estimated CV risk, presence of diabetes, and cholesterol levels at baseline. These observations should be taken into account in order to optimize health resources.
