Self-reported adherence to diet and preferences towards type of meal plan in patient with type 2 diabetes mellitus. A cross-sectional study.

BACKGROUND AND AIMS: Few studies have evaluated the attitudes of patients with type 2 diabetes mellitus (T2DM) towards the given dietary plans. In this study, we aimed to evaluate: i) the self-reported adherence of T2DM patients to the prescribed diets; ii) the use of other types of diet schemes; iii) the patients' preferences towards the type of meal plans. METHODS AND RESULTS: A 16 multiple-choice items questionnaire was administered to 500 T2DM patients; 71.2% (356/500) of them had the perception of having received a dietary plan; only 163/356 declared to be fully adherent. The latter had lower BMI (25.8 ± 4.5 vs 29.1 ± 4.5 kg/m2, p < 0.001) than patients who were partly adherent. Among patients not following the given diet, 61.8% was eating in accordance to a self-made diet and 20.9% did not follow any diet. Only a few patients (2.4%) had tried a popular diet/commercial program. Most patients preferred either a "sufficiently free" (201/500) or a "free" (218/500) scheme. The use of supplements attracted younger, obese individuals, with higher education, and most managers. In a multinomial regression model, age and diabetes duration were inversely associated with the choice of a "rigid" scheme, diabetes duration and glycated hemoglobin levels were inversely correlated with a "free" diet choice, obesity was associated with a "strategic" scheme choice, while lower education (inversely) and obesity (directly) correlated with the preference for "supplement use". CONCLUSIONS: Socio-cultural/individual factors could affect attitudes and preferences of T2DM patients towards diet. These factors should be considered in order to draw an individually tailored dietary plan.

Nutritional Care Needs in Elderly Residents of Long-Term Care Institutions: Potential Implications for Policies.

OBJECTIVES: To collect information on actual nutritional intervention requirements in long-term care institutions and on the role of institutional factors in nutritional care. DESIGN: A cross-sectional analysis of baseline data (collected between September 2011 and September 2013) within the context of a multicenter prospective cohort study. SETTING: Nineteen long-term care institutions. PARTICIPANTS: Thirteen hundred and ninety-four resident elderly (age ≥60 years). MEASUREMENTS: The prevalence of nutritional derangements (MNA-Short Form) and the need to introduce nutritional interventions on the residents. RESULTS: Prevalence of malnutrition and risk of malnutrition were 35.2% [95%CI, 32.8-37.8] and 52.6% [95%CI, 50.0-55.2], respectively. Malnutrition was more frequent upon admission and in larger institutions (≥50 beds). Overall, 50% of the residents requiring an individualized nutritional care plan (any type) were not receiving it. Oral diet, the use of fluid thickeners and oral nutritional supplements had to be introduced in 306 (22.5%), 201 (15%) and 175 (13%) residents, respectively. The need to implement the oral diet was mainly due to inadequacy of texture according to chewing and swallowing capabilities. In gender and age-adjusted multivariable logistic regression models, nutritional interventions were associated with worse nutritional status (P<0.001 for all). Moreover, while the duration of stay was unrelated to the need for nutritional interventions, we observed that residents living in larger long-term care institutions (≥50 beds) were more likely to require improvement in nutrition care. CONCLUSIONS: In long-term care elderly residents nutritional derangements are very common, underdiagnosed and undertreated. Nutritional screening should be part of routine care. However, also the systematic involvement of a nutritional care specialist appears to be an urgent need, particularly in larger institutions where the standards of care are likely to be lower.

Use of a lipid-lowering food supplement in patients on hormone therapy following breast cancer.

AIM: The aim of this paper was to determine the activity of a natural nutraceuticals combination (AP=Berberine+Red Yeast Rice) on dyslipidemia which frequently persists after life style changes in patients on hormone-therapy following breast cancer (HT-BC). METHODS: Twenty-one HT-BC patients, free of tumor, mean age 59.9 years, BMI 28,9 kg/m2, waist circumference 95.9 cm, with altered lipid profile (total cholesterol 269.0 mg/dL, high-density lipoprotein (HDL) cholesterol 54.9 mg/dL, low-density lipoprotein (LDL) cholesterol 184.0 mg/dL, and triglycerides 263.3 mg/dL) were recruited. They were recommended a 3-month period of diet followed by a 3-month period of treatment with AP 1 tablet/day. AP tablets contain berberine 500 mg, red yeast rice extract 200 mg (equivalent to 3 mg monacolins), policosanol 10 mg, folic acid 0.2 mg, coenzyme Q10 2 mg, and asthaxantin 0.5 mg. RESULTS: The lipid profile was significantly improved by AP vs. diet: 1.8% decrease in total cholesterol on diet and a further 15.3% decrease with AP vs. diet (P<0.001); a 3.1% decrease in LDL cholesterol after diet and an 18.9% decrease after AP treatment vs diet alone (P<0.01); a 2.3% decrease in triglycerides after diet alone and a 36.5% decrease after AP vs. diet (P<0.05). CONCLUSION: Adequate life style therapy is effective in reducing, but not in normalizing, the lipid profile in patients on hormone-therapy following breast cancer. The use of natural nutraceuticals as AP, combined with diet, leads to a good therapeutic response and optimal acceptance by the patients.

[The role of food in the workplace for health promotion and education to the future]. / Il ruolo dell'alimentazione sui luoghi di lavoro per la promozione del benessere organizzativo e l'educazione al futuro.

Health promotion and education to the future and sustainability are a new potential approach in order to try to reduce diet- and lifestyle-related diseases (cancer, metabolic disorders, obesity, neurodegenerative diseases). Inclusion of educational pathways associated to food consumption out of the home, especially in the workplace, may represent a brand new strategy of intervention, an alternative to the disappointing results of more traditional information-educational strategies implemented so far.

[The team approach]. / La conduzione in team.

Teamwork is emerging like a model of prevailing reference in many working fields: the interaction and, above all, integration between several persons can be an instrument to empower the individual skills, allowing to reach different and higher levels of creativity and efficiency than the sum of the single members' capacities. However, the capacity of interaction, tolerance, and focusing on the problem is required to the members who also need training for this way of working. After a brief historical summary of some ''creative groups'' experiences in the fields of literature, science and arts, a vast review of theoretical model references is presented. Starting from specific North-American guidelines, a hypothesis of nutritional teamwork is introduced. This hypothesis aims at optimizing therapeutic interventions, at the critical review of the provided services and at a greater care for the cost-benefit ratio.

[Postoperative fistulas after gastrectomy: risk factors in relation to incidence and mortality]. / Fistole postoperatorie dopo gastrectomia: fattori di rischio in relazione ad incidenza e mortalità.

The relations between incidence and prognosis of postoperative fistulas after gastrectomy and some different variables were analysed in the present retrospective study. Thirteen digestive fistulas of 113 patients (11.9%) submitted to gastrectomy during the period 1989-1994 represent the study population. The incidence of postoperative fistulas was compared to the kind of gastric pathology, to the extension of gastrectomy, to different nutritional (serum haemoglobin, albumin and transferrin level, weight loss) and immunological factors (serum lymphocytes) and, for oncological patients, to the stage of the disease. Incidence was directly related to the extension of gastrectomy, to serum albumin and haemoglobin level, and to weight loss rate. The results were not statistically significant at Kruskal-Wallis and ANOVA tests. No relation was found between incidence of fistulas and serum transferrin level, number of lymphocytes and adoption of early postoperative enteral nutrition. Six patients had spontaneous closure of the fistula with conservative therapy. Seven patients required reoperation because of abdominal sepsis (53.8%). Three patients died (23%). Although spontaneous closure, reoperation and mortality were related to nutritional and immunological state, no examined variables showed a statistically significative relation. The adoption of early postoperative enteral nutrition was not related to the prognosis, unlike the stage of the disease: patients submitted to reoperation had a TNM III or IV stage; dead patients had a TNM IV stage. Treatment of metabolic-nutritional unbalance can prevent anastomotic failure and fistula after gastrectomy and improve the prognosis. The relation between early postoperative enteral nutrition and incidence and prognosis of postoperative fistulas remains unclear.

[Total parenteral nutrition in critical patients. The metabolic-nutritional aspects and effects on immune function of 2 different isocaloric-isonitrogenous regimens]. / Nutrizione parenterale totale (NPT) in pazienti critici. Aspetti metabolico-nutrizionali ed effetti sulla funzione immunitaria di due differenti apporti isocalorici-isoazotati.

The aim of this investigation was to compare, in a randomized short-term study the effects on some parameters evaluating lipid metabolism, nutritional status and immune function of two different patients. Particularly, the influence of the intravenous (i.v.) infusion of a fat emulsion on above-mentioned parameters was evaluated. The two regimens (G and GL) were isocaloric (about 30 kcal.kg-1.d-1 non protein energy) and isonitrogenous (about 0.27 g.kg-1.d-1 nitrogen); the only difference was the source of non-protein calories administered. Regimen G consisted of glucose-based TPN (100% of non-protein energy as glucose) whereas, in regimen GL (glucose-lipid-based TPN), the 55% of non-protein caloric supply was given as glucose and 45% as lipids. 9 of the patients were randomly assigned to receive regimen GL (group GL) and 8 to receive regimen G (group G). TPN was delivered through a central vein catheter for 8 days; during this period no hepatic or metabolic complications have been observed. Clinical and laboratory tests were performed at day 0 (enrollment), at day 4 (after 4 days of TPN) and at day 8 (at the end of TPN). Both regimens of TPN were able to induce an improvement of the nutritional status and serum prealbumin (TBPA) significantly increased in all patients (p < 0.05). The results of the immune measurements showed that no significant change in immune function during the administration of either regimen occurred. However, in group GL, we observed a slight, non significant change in the percentage numbers of T-cells subpopulations that resulted in a decrease in the ratio of helper to suppressor T-cells (H:S). Serum lipids and lipoprotein profile didn't change significantly in group GL. On the contrary, in group G, we observed a significant decrease in serum concentrations of HDL cholesterol (p < 0.05), LDL cholesterol and apo A1 (p < 0.01) while total cholesterol remained unchanged; a non significant rise in serum triglyceride also occurred, These results show that the two regimens had a similar impact on nutritional status in both groups. The i.v. infusion of the fat emulsion didn't alter lipid profile and was not associated with an impairment of some aspects of the immune function. In conclusion, our results confirm that fat emulsions represent an important component of i.v. nutritional support regimens and should continue to be used when and where indicated in short-term TPN. However, long-term effects of i.v. infusion of fat emulsions on the immune systems should be further investigated, in a more substantial number of patients.

[Percutaneous endoscopic gastrostomy]. / Gastrostomia endoscopica percutanea.

Surgical gastrostomies were first performed in the middle of the 19th century and modified during the following years, but the most important technical improvement was percutaneous endoscopic placement (PEG), in 1980 by Ponsky and Gauderer. This technique doesn't require anesthesia and it in possible also in patients with contraindications to surgical gastrostomy. The simple procedure involves a shorter hospitalization, lower risks and reduced costs. Many authors already reported the good results of this new technique, that can be performed on a day-hospital regimen as well. The main indications are head and neck cancers, neurologic diseases involving food intake capacity, cancer cachexia, obstruction of the GI tract when there is enough space for an endoscopic procedure. Every disease that can compromise food intake for a period longer than 60 days can find an indication in placing a percutaneous gastrostomy. The advantage for the patient is a much better psychological tolerance compared with a naso-gastric tube. Also the incidence of mechanical complications of a PEG is much lower. In our experience from October '90 to July '92 we followed 34 patients with PEG, 22 males and 12 females, with mean age of 69 years (range 41-88). We used 9-French tube placed using the pull-method technique. All patients received antibiotic therapy for 5 days. About 12 hours after PEG placement all patients began using the gastrostomy, initially with the administration of electrolyte solutions and later with enteral polymeric formulas. The constant increase led all patients to a 1500 non protein calories daily intake in 3-4 days.(ABSTRACT TRUNCATED AT 250 WORDS)

[Possibilities and limitations of nutritional support in Crohn disease]. / Possibilità e limiti del supporto nutrizionale nella malattia di Crohn.

Crohn's disease involves a great risk of malnutrition. Malabsorption, bacterial contamination, frequent abdominal surgery, meal-related pain, protein loss through the damaged mucosa contribute to creating nutritional problems. Malnutrition can worsen the outcome, both in medical and surgical patients, and deteriorate an often already altered immune response. Weight loss, low levels of blood protein, electrolytes, micronutrients and vitamins are usually related to the extension of the mucosal damage. Nutritional assessment can be difficult due to oedema and bleeding, who interfere with both clinical and laboratory evaluation. The exact amount of nitrogen, lipids, minerals stool loss can be useful. It is widely accepted the use of nutritional support in Crohn's disease, but many Authors do not agree concerning the route (enteral or parenteral) and the kind of nutrient to be used. Still controversial is the role of nutrition: just support or real therapy? Most recent hypothesis concerning the pathogenesis of Crohn's disease indicate food and/or bacterial antigens as involved in determining the pathology. The "bowel rest", considered for many years as a fasting period necessarily supported by parenteral nutrition, can also be obtained by the temporarily reduction or stop in presenting those antigens to the bowel mucosa. This new concept can be achieved not only by parenteral nutrition, but with an enteral elemental diet as well. The elemental diet contains all nutrients in the simplest way and thus succeeds in lowering or eliminating the antigenic power. The reported results seem to indicate an equivalence of enteral and parenteral nutrition; anyway enteral is advisable when feasible, being more physiological and less expensive and involving a lower risk of serious complications.(ABSTRACT TRUNCATED AT 250 WORDS)

[Role of nutritional support and physical exercise in the dyslipidemia of renal transplantation]. / Ruolo dell'apporto nutrizionale e dell'esercizio fisico nella dislipidemia del trapianto di rene.

The purpose of the study is to evaluate the effect of diet and physical exercise on the dyslipemia of renal transplant (RT) patients 52 pts, transplanted between 12/85 and 4/87, subdivided into 2 groups (A and B), were studied. Characteristics of the diet adopted in patients in group A are: low carbohydrates, moderate animal protein, unsaturated and polyunsaturated fat in high rate. The second group had a lower animal protein and more fiber rich diet than the first one and a program of PE. By comparing A and B1 we noticed and increase in body weight, more slight in the group B, at the 24 months (56 +/- 8 59 +/- 10 vs 59 +/- 10 61 +/- 10). The study of lipid behaviour has showed a trend to normalization of triglycerides at 24 months in A (189 +/- 88 106 +/- 33) and in B1 (173 +/- 81 103 +/- 40), more evident normalization of cholesterol in group B1 (195 +/- 72 185 +/- 42), and increase of CT-HDL in A (42 +/- 12 63 +/- 17) and in B1 (44 +/- 10 61 +/- 14, p less than 0.05). It should be noted that CT-LDL increase in A (100 +/- 34 131 +/- 40) but not in B1 (103 +/- 35 111 +/- 33). With the aim of this program we obtained a positive effect on DL with a slight increase in body weight, a significant increase in CT-HDL without variation of total CT and CT-LDL levels.

[Nutritional support in non-Hodgkin's lymphoma treated with polychemotherapy MACOP-B cycle]. / Supporto nutrizionale nel linfoma non-Hodgkin in trattamento con ciclo polichemioterapico MACOP-B.

The collateral effects of antineoplastic therapy often lead to a deterioration of the cachectic condition induced by the presence of the tumour itself. This study analysed the effects of a programme of dietary surveillance/support in patients with non-Hodgkin's lymphoma undergoing a cycle of MACOP-B polychemotherapy. During the entire course of therapy patients were followed weekly by a nutritional specialist and a dietician in order to assess and if necessary modify food intake, also in relation to the onset of collateral effects. Using this programme it was observed that a satisfactory nutritional state was maintained during the entire cycle, with an increased food intake compared to the start of the cycle and to conditions of good health.

[The role of the intestine in the pathogenesis and treatment of multiple organ failure]. / Il ruolo dell'intestino nella patogenesi e nel trattamento della "multiple organ failure".

Infection and sepsis remain major causes of death in medical and surgical services, despite the availability of potent antibiotics, aggressive surgery and close monitoring of patients in intensive-care units. Actually the terminology to define this type of events in multiple organ failure: we considered the role of intestine in its pathogenesis and its management.

[The role of early protein restriction in patients with initial renal insufficiency]. / Il ruolo di una precoce restrizione proteica in pazienti affetti da insufficienza renale iniziale.

The effect of early protein restriction (0.6 g:kg/p.i./die) in patients suffering from initial kidney failure for a period of two years has been studied. The hypoprotein diet proved effective in slowing development of kidney damage in so far as a stabilization was observed in renal function parameters during the hypoprotein diet period compared to the non-diet period.

[Influence of coffee on plasma lipids]. / Influenza del caffè sui lipidi plasmatici.

The influence of coffee on plasma lipids has been largely investigated during the last twenty years, but still many doubts remain about this subject. For this reason the influence of the assumption of coffee on plasma lipids, in healthy people, during six weeks has been studied. The coffee was prepared with an Italian coffee-machine (moka). No relationship was found between coffee assumption and increase of hematic cholesterol.

[Role of diet in the treatment of constipation. Review of the literature]. / Ruolo della dieta nel trattamento della stipsi. Revisione della letteratura.

Constipation represents a common social phenomenon today, correlated with the habits of diet and life. Many studies have shown the lack of alimentary fiber as a cause of constipation. In analyzing the different types, the characteristics, the physical and metabolical action of fiber, it has been shown that it is necessary to introduce fiber into the everyday diet to be able to prevent or cure constipation. In addition, it has been seen that there has been a reduction in the consumption of fiber in many nations and some reasons have been investigated.
