Critical evaluation of the questionnaires assessing adherence to the Mediterranean diet that are based on servings.

BACKGROUND AND AIMS: The Mediterranean Diet (MD) is characterized by a high intake of vegetables, fruit, legumes, nuts, and olive oil, and moderate fish, dairy, and wine intake. A high adherence to MD has been associated with numerous health benefits, including reduced risk of chronic diseases such as cardiovascular disease, cancer, and type 2 diabetes. The clinical assessment of MD adherence is complicated by the absence of a univocally accepted tool and by the abundance of questionnaires developed to determine adherence, whose reliability and validity is uncertain. In this inter-associative document, we critically evaluated servings-based questionnaires for the assessment of MD adherence, aiming to identify the most valuable tool for the use in clinical practice. METHODS AND RESULTS: For each questionnaire, we analyzed the structure, evidence on health-related outcomes and agreement with the recommendations of MD. We found that most questionnaires do not accurately reflect the principles of MD in terms of the food groups and their optimal consumption frequency. Additionally, the comparison of questionnaires revealed low agreement and some concerns with regard to the scoring assumptions. CONCLUSIONS: Among the available questionnaires, we suggest the use of the 15-Items Pyramid based Mediterranean Diet Score (PyrMDS), which is the one with fewer flaws and a strong supporting body of theoretical and scientific evidence. The use of the PyrMDS may facilitate the assessment of MD adherence in clinical practice, which is instrumental in reducing the risk of non-communicable chronic diseases.

[Chronic pain in the obese: a quali-quantitative observational study]. / Dolore cronico nell'obesità: studio osservazionale quali-quantitativo.

INTRODUCTION: Obesity (Ob) is one of the major issues for the public health care system with a constantly increasing prevalence. Chronic Pain (CP), on the other hand, is a pathological condition as severe and prevalent as the former. Ob and CP are not only pathological conditions, they also are important factors of risk for the onset of a number of morbid conditions. MATERIALS AND METHODS: In our study we have enrolled 182 patients with Ob, to whom we have asked to fill a brief questionnaire with the purpose of evaluating prevalence and characteristics of CP, therapeutic attitude and its results, as well as the knowledge of the Law n. 38 - 15/03/2010. RESULTS: From the analysis of gathered data, CP is present in the 39% of subjects with Ob (73.2% of females and 23.9% of males) and proportionally increases as BMI increases. The majority of patients (48%) shows pain at articular level, and a "pin" and a "gripping" pain are the two types of pain that are mostly described. Almost all the subjects enrolled (90%) suffer of a pain reported at a moderate to intense level. 15% circa of the patients do not take any therapy, while FANS have resulted to be the most used drugs among them (over 50% of the patients) and the 45% of the subjects have currently reported not to have a good control over the pain. The Law n. 38 has been reported unknown by the 8.2% of the investigated sample. CONCLUSIONS: The study has demonstrated a substantial association between the Ob and CP, particularly in the female gender, the clinical relevance of pain, its BMI-dependent tendency, the inadequacy of the therapy and the widespread lack of awareness and attention to the themes and issues of pain.

[Chronic pain in the diabetic patient: a quali-quantitative observational study]. / Dolore e diabete mellito: studio osservazionale quali-quantitativo.

AIM: The purpose of this study is to evaluate the prevalence and characteristics of pain in subjects affected by Diabetes Mellitus (DM), to assess approach and therapeutically valid outcomes as well as the knowledge of the Law n. 38/15/03/2010 of the Italian Government ("Dispositions to guarantee the access to the Palliative Cares and Pain Therapy"). MATERIALS AND METHODS: We have enrolled 462 patients affected by DM [242 (52.4%) males, 209 (42.5%) females; while in 11 (5.1%) cases the gender has not been specified], with characteristics as follows: 62 patients (13.4%) affected by T1DM (37 males and 25 females) e 400 patients (86.6%) affected by T2DM (224 males e 176 females). The average age was of 65.2 years old (range 20-91). All the patients have been presented with an original questionnaires based on 10 questions. RESULTS: 221 subjects (48%) have claimed to have experienced pain; 60% within the females, 38% within the males (p<0.001). 31% of these are to be included among the patients with T1DM, 50.5% among those with T2DM (p<0.01). The presence of chronic pain has been acknowledged by 162 subjects (35%). As per chronic pain, this has been described as articular pain by 128 patients (80%), while 63 (38%) located the pain through the spine and 29 (18%) throughout the muscles. Chronic pain was described as moderate by 73 subjects (45%), intense by 59 (36%), feeble by 15 (9%), utterly intense by 5 (3%), moderate/intense by 1 (1%). The drugs for treating the chronic pain used by the patients have been enlisted as follows: FANS (41%), paracetamol (30%), glucocorticoids (3%), weak opioids (2%); 27% of subjects have received no therapy. As for the Law 38/2010, only 8% have said they have had news of it. CONCLUSIONS: The data gathered in this study have drawn attention on the fact that the presence of pain is higher in female gender, with a prevalence of 60% compared to the 38% of the male gender. It has been observed no relation with the age range, in particular no proportional increase level of pain has been observed, although the higher peak of prevalence has been experienced in the age range between 70-79, both for pain in general and for chronic pain. Speaking about efficacy of the treatment, almost 50% of the subjects have received no improvement from the therapy.

Bariatric Surgery for Patients with Overweight/Obesity. A Comprehensive Grading Methodology and Network Metanalysis of Randomized Controlled Trials on Weight Loss Outcomes and Adverse Events.

This study aims to compare different types of metabolic bariatric surgery (MBS) with lifestyle intervention/medical therapy (LSI/MT) for the treatment of overweight/obesity. The present and network meta-analysis (NMA) includes randomized trials. MBS was associated with a reduction of BMI, body weight, and percent weight loss, when compared to LSI/MT, and also with a significant reduction of HbA1c and a higher remission of diabetes. Meta-regression analyses revealed that BMI, a higher proportion of women, and a longer duration of trial were associated with greater effects of MBS. The NMA showed that all surgical procedures included (except greater curvature plication) were associated with a reduction of BMI. MBS is an effective option for the treatment of obesity. The choice of BMI thresholds for eligibility for surgery of patients with different complications should be performed making an evaluation of risks and benefits in each BMI category.

Apple polyphenol extracts prevent aspirin-induced damage to the rat gastric mucosa.

Aspirin causes gastroduodenal ulcers and complications. Food bioactive compounds could exert beneficial effects in the gastrointestinal tract. We evaluated whether apple polyphenol extract (APE) reduced aspirin-induced injury to the rat gastric mucosa. Rats were treated with APE (10(-4) m catechin equivalent) before oral aspirin (200 mg/kg). Cyclo-oxygenase-2 (COX-2), transforming growth factor-alpha (TGF alpha) and heparin-binding epidermal-growth-factor-like growth factor (HB-EGF) mRNA and protein expression were assessed by RT-PCR and Western blot analysis, respectively; malondialdehyde (MDA) was determined by HPLC; gastric secretion was evaluated in pylorus-ligated rats. APE decreased acute and chronic aspirin injury both macroscopically and microscopically (approximately 50 % decrease in lesion score; P < 0.05). Aspirin up-regulated mRNA and protein expression of COX-2 and HB-EGF, but not of TGF alpha; APE reduced aspirin-induced mRNA and protein over-expression of COX-2 and HB-EGF; aspirin significantly increased gastric MDA and this effect was counteracted by APE pre-treatment. APE did not significantly affect gastric acid secretion. In conclusion, APE reduces aspirin-induced gastric injury independently of acid inhibition. We speculate that APE might be of therapeutic use in the prophylaxis of aspirin-related gastropathy.

Overactivity of the intestinal endocannabinoid system in celiac disease and in methotrexate-treated rats.

The endocannabinoid system is upregulated in both human inflammatory bowel diseases and experimental models of colitis. In this study, we investigated whether this upregulation is a marker also of celiac disease-induced atrophy. The levels of the cannabinoid CB(1) receptor, of the endocannabinoids, anandamide, and 2-arachidonoyl-glycerol (2-AG), and of the anti-inflammatory mediator palmitoylethanolamide (PEA) were analyzed in bioptic samples from the duodenal mucosa of celiac patients at first diagnosis assessed by the determination of antiendomysial antibodies and histological examination. Samples were analyzed during the active phase of atrophy and after remission and compared to control samples from non-celiac patients. The levels of anandamide and PEA were significantly elevated (approx. 2- and 1.8-fold, respectively) in active celiac patients and so were those of CB(1) receptors. Anandamide levels returned to normal after remission with a gluten-free diet. We also analyzed endocannabinoid and PEA levels in the jejunum of rats 2, 3, and 7 days after treatment with methotrexate, which causes inflammatory features (assessed by histopathological analyses and myeloperoxidase activity) similar to those of celiac patients. In both muscle/serosa and mucosa layers, the levels of anandamide, 2-AG, and PEA peaked 3 days after treatment and returned to basal levels at remission, 7 days after treatment. Thus, intestinal endocannabinoid levels peak with atrophy and regress with remission in both celiac patients and methotrexate-treated rats. The latter might be used as a model to study the role of the endocannabinoid system in celiac disease.

Impact of Insulin Degludec in Hospitalized Patients With and Without Type 2 Diabetes Requiring Parenteral/Enteral Nutrition: An Observational Study.

INTRODUCTION: Hyperglycemia in inpatients is a major problem, especially when nutritional support is required. This study aims to assess the impact of treatment with insulin degludec (IDeg) on mean blood glucose (BG) and glycemic variability in noncritical hospitalized patients with and without type 2 diabetes (T2DM) receiving enteral and/or parenteral nutrition (EN, PN). METHODS: Mean BG and glycemic variability from admission up to 7 days of hospitalization were evaluated in consecutive cases with and without T2DM. Percentage of coefficient of variation (CV) for glucose was used to express glycemic variability. RESULTS: Overall, 26 patients (13 with and 13 without T2DM) were admitted to the hospital for any cause. Subjects were 65.4% men and they were mainly elderly (mean age 66.3 ± 13.4 years). PN was administered in 88.5% of patients and EN in 19.2%. At admission, mean HbA1c level was 5.9 ± 0.7% in patients without diabetes and 9.1 ± 2.5% in patients with T2DM. During hospitalization, mean daily BG levels changed from 151 ± 47.3 mg/dl (day 1) to 157 ± 66.7 mg/dl (day 7) in patients without diabetes and from 210 ± 66.5 mg/dl to 192 ± 48.6 mg/dl in patients with T2DM. CV decreased from 14% (day 1) to 11% (day 7) in patients without diabetes and from 20% (day 1) to 9% (day 7) in patients with T2DM. No symptomatic or severe hypoglycemia occurred. CONCLUSIONS: Despite the small sample size and the lack of control group, this study represents the first proof-of-concept that IDeg in hospitalized patients with or without T2DM who require nutritional support has the potential to maintain stable levels of BG and reduce glycemic variability.

Rationale and design of the Early Sleeve gastrectomy In New Onset Diabetic Obese Patients (ESINODOP) trial.

No randomized clinical trials (RCTs) have yet evaluated the bariatric surgery's efficacy and safety in patients newly diagnosed with type 2 diabetes mellitus (T2DM). The aim of this multicenter RCT is to compare bariatric surgery, particularly laparoscopic sleeve gastrectomy (LSG), with conventional medical therapy (CMT) in obese patients (body mass index between 30 and 42 kg/m2) newly diagnosed with T2DM and without any diabetes-related complications at any stage. A total of 100 eligible patients will be randomized at a 1:1 ratio to undergo one of the two planned treatments and will be followed for at least 6 years after randomization. The main objective of the ESINODOP trial is to investigate the efficacy of LSG compared with CMT alone in inducing and maintaining a remission of T2DM (defined as HbA1c levels ≤6.0 %, without active pharmacologic therapy after 1 year). The remission of T2DM will also be evaluated with the criteria provided by the American Diabetes Association (ADA), and the additional parameters such as adverse event rates, micro- and macrovascular complications, weight loss, gastrointestinal hormones, and quality of life will be compared. The study started on September 2015 and the planned recruitment period is 3 years. Patient recruitment and follow-up take place in the two diabetology and nutrition centers participating in the study, which are performed on a national basis. The ESINODOP trial is designed with the intent of comparing the efficacy of CMT alone to that of CMT in conjunction with LSG performed at the time of diabetes diagnosis in mildly obese diabetic patients. Currently, patients with these characteristics are not eligible for bariatric/metabolic surgery.

Long-term medical complications after malabsorptive procedures: effects of a late clinical nutritional intervention.

OBJECTIVE: The growing prevalence of severe obesity, combined with the failure of conservative treatments, has led to a significant spread of bariatric surgical procedures. The aim of this study was to emphasize the need of adequate presurgery patient selection and close follow-up after malabsorptive procedures for bariatric surgery. METHODS: The study retrospectively evaluated 25 (20 F, 5 M; mean age 43 ± 13 y) obese patients (mean weight before intervention 134 ± 30.7 kg, body mass index 50.7 ± 10.1 kg/m(2)) attending our outpatient clinical nutrition unit for severe malabsorption and secondary malnutrition after surgical intervention that had been performed outside the regional area. RESULTS: All patients received personalized dietetic indications; in 12 of 25 (48%) cases integrated by oral protein supplements and in 5 of 25 (20%) by medium chain triglycerides. According to screening exams, patients were prescribed oral/parenteral iron, vitamins A, B group, D, and folate supplementation. In 14 of 25 (56%) patients, parenteral hydration and in 4 of 25 (16%), long-term parenteral nutrition was required. Five patients required hospitalization for severely complicated protein-energy malnutrition. CONCLUSION: Nutritional deficiencies are common after malabsorptive procedures for bariatric surgery; these can be present or latent before surgery, frequently going unrecognized and/or inadequately treated particularly when patients are not strictly followed up by the operating center. Despite the adequate-even intensive-intervention, clinical nutritional status moderately improved in all patients.

Butyrylcholinesterase as a prognostic marker: a review of the literature.

BACKGROUND: Butyrylcholinesterase (BChE) is an α-glycoprotein synthesized in the liver. Its serum level decreases in many clinical conditions such as acute and chronic liver damage, inflammation, injury and infections, and malnutrition. METHODS AND RESULTS: This review collects the main evidence on the emerging role of butyrylcholinesterase as a prognostic marker of liver and nonliver diseases as well as a marker of protein-energy malnutrition and obesity. In fact, serum concentrations and BChE activity seem to accurately reflect the availability of amino acidic substrates and/or derangement in protein synthesis due to hepatocellular damage. In cancer, with or without liver impairment, serum BChE levels serve as an accurate functional and prognostic indicator, useful for monitoring clinical and therapeutic interventions according to patients' prognosis. In the absence of inflammation, BChE could also serve as an index of the effectiveness of nutritional support. CONCLUSIONS: Serum BChE assessment should be included in routine clinical diagnostic procedures to evaluate patient clinical conditions, in particular in cases of inflammation and/or protein-energy malnutrition.

Effects of laparoscopic sleeve gastrectomy in patients with morbid obesity and metabolic disorders.

PURPOSES: Obesity and its correlation with other pathological conditions determine the onset of the metabolic syndrome, which exposes the patient to a higher risk of major cardiovascular complications. Laparoscopic sleeve gastrectomy (LSG) is a bariatric surgical procedure that appears to influence both the reduction of fat mass and the action of some gastrointestinal hormones. PATIENTS AND METHODS: Between January 2011 and July 2013, 23 patients with morbid obesity underwent LSG and follow-up. In the evaluation of patients, the criteria for metabolic syndrome given by the International Diabetes Federation were followed. A multidisciplinary team of experts evaluated patients before surgery and in subsequent scheduled postoperative visits at 7, 30, 60, and 90 days and 4, 5, 6, 9, and 12 months. Anthropometric and metabolic parameters were analyzed. RESULTS: The mean excess weight loss was 8.57±3.02%, 17.65±6.40%, 25.47±7.90%, 33.76±9.27%, 41.83±10.71%, 46.02±13.90%, 52.60±14.05%, 58.48±16.07%, and 62.59±21.29% at 7, 30, 60, and 90 days and 4, 5, 6, 9, and 12 months, respectively. In the same observational period there was an excellent improvement of metabolic indices. None of the patients previously taking prescribed hypoglycemic drugs restarted therapy. Mean fasting plasma glucose significantly decreased compared with the preoperative values. Blood pressure had a statistically significant improvement. Modification in the lipid profile was more variable. During the period of observation 22 of 23 patients reported in this study did not fit the criteria for metabolic syndrome. CONCLUSIONS: Morbid obesity and related diseases may benefit from a surgical approach in selected patients. Randomized controlled trials are needed to evaluate the role of LSG.
