RESUMEN
Pancreatic cancer (PC) remains one of the most aggressive tumors with an increasing incidence rate and reduced survival. Although surgical resection is the only potentially curative treatment for PC, only 15-20% of patients are resectable at diagnosis. To select the most appropriate treatment and thus improve outcomes, the diagnostic and therapeutic strategy for each patient with PC should be discussed within a multidisciplinary expert team. Clinical decision-making should be evidence-based, considering the staging of the tumor, the performance status and preferences of the patient. The aim of this guideline is to provide practical and evidence-based recommendations for the management of PC.

INTRODUCTION: Vitamin D deficiency produces inadequate bone mineralization, proximal muscle weakness, abnormal gait and increased risk of falls and fractures. Moreover, in epidemiological studies, has been associated with increased risk of cancer, autoimmune diseases, type 1 and 2 diabetes, rheumatoid arthritis, multiple sclerosis, infectious diseases, cardiovascular diseases and depression. When synthesis through the skin by sun exposure is not possible and the patient can not eat by mouth, as in the advanced stages of various neurological diseases, the supply of vitamin D has to be done by enteral nutrition. OBJECTIVES: The aim of this study is to review the role of vitamin D in a common group of neurological conditions that often require artificial nutrition and analyze whether the vitamin D of different enteral nutrition formulas is adequate to meet the needs of this group of patients. RESULTS: Numerous studies have shown the association between vitamin D deficiency and increased incidence of dementia, stroke and other neurodegenerative diseases. Interventions aimed to increase levels of vit. D and its effects on functional (falls, pain, quality of life) and cardiovascular goals (cardiovascular death, stroke, myocardial infarction, cardiovascular risk factors) have obtained as highlight data a clear reduction of falls and fractures, while the evidence for the other parameters studied is still limited and inconsistent. The content of calcium and vitamin D of enteral formulas is legislated in our country. The total amount of vitamin D for a daily intake of 1,500-2,000 kcal ranges between 300 and 1,600 IU/d (mean ± SD: 32.9 ± 8.5 mg/100 kcal) in the complete formulas for enteral nutrition most commonly used. 50% of the diets studied, for an intake of 2,000 kcal/d, and 90% for an intake of 1,500 kcal/d, provide less than 600 IU/d of vitamin D. DISCUSSION: Some revised recently guidelines published recommendations of daily intake of vitamin D. The document published by the U.S. Institute of Medicine recommended for adults between 19 and 70 years, 600 IU/d and up from 70, proposes 800 IU/d of vitamin D. These amounts are deemed insufficient by other scientific societies to state that to achieve blood levels of 25 (OH) D equal or greater than 30 ng/ml may be required a daily intake of 1,500-2,000 IU and a number two or three times higher if previous deficiency exists. CONCLUSIONS: Further controlled studies are needed to ascertain which is the appropriate dose of vitamin D in advanced stages of neurological disease, where sun exposure is difficult and unlikely. We suggest that the vitamin D content should probably be reconsidered in enteral nutrition formulas, which, in light of recent publications appear as clearly insufficient for standard energy intakes (1,500-2,000 kcal).

We report the case of a patient with recurrent severe hypocalcemia, secondary to hypomagnesaemia, and prerenal renal failure, due to ileostomy losses after a colectomy, who needed several admissions to the hospital through more than one year. Finally, he was successfully treated by self-administered subcutaneous magnesium: he reached and maintained normal levels of serum calcium, magnesium and PTH, no more hospital admission were needed and he resumed a normal life.

Artificial nutrition support forms part of the basic care of critical patients. Enteral feeding has been shown to be better than total parenteral nutrition at improving morbidity (infectious complications) and reducing the length of hospital stays, number of days with mechanical ventilation, and costs. As with any other treatment, enteral feeding has associated complications and side effects which should be understood and treated in order to obtain the greatest benefit from it and reduce possible adverse effects. In this review, we attempt to provide a practical summary of the use of enteral feeding in critical patients. We cover the management of the most frequent associated complications, based on new studies and current scientific evidence. The review is intended to serve as a practice guide for the routine care of severely ill patients.

INTRODUCTION: The creation of a Nutrition Unit (NU), with a specialized professional establishing homogenous criteria and standardized proceedings for the use of parenteral nutrition (PN) may improve the clinical course of the patients and decrease the number of technique-related complications. OBJECTIVES: To describe the clinical characteristics of the patients submitted to PN at our Center. To assess the effect that the implementation of a NU has on the patients clinical course, and to know the frequency of mortality and hospital stay duration after the implementation of the NU at the University Hospital Complex of Albacete. MATERIAL AND METHODS: We reviewed the clinical charts of the patients receiving PN during the two years before and the two years after the creation of the NU by means of a two-period cohort study. RESULTS: Of the 390 patients, 100 belonged to the cohort before the NU and 290 to the following cohort. 61.3% of the patients were admitted at the surgery department. 25% of the patients had a personal history of digestive pathology. Among the reasons for ordering PN to the NU, surgical complications were the most common (66.7%). Oncologic abdominal surgery was the most common category (39.3%) out of the six in which the patients have been categorized. The mortality rate for the first cohort was 29% and for the second cohort 12.8% (p < 0,00). The average of stay days for the first cohort was 29.53 days and 27.67 days for the second one (p = 0.41). CONCLUSIONS: The implementation of a NU has a positive impact on the clinical course of hospitalized patients submitted to PN.

Obesity-induced chronic inflammation leads to activation of the immune system that causes alterations of iron homeostasis including hypoferraemia, iron-restricted erythropoiesis, and finally mild-to-moderate anaemia. Thus, preoperative anaemia and iron deficiency are common among obese patients scheduled for bariatric surgery (BS). Assessment of patients should include a complete haematological and biochemical laboratory work-up, including measurement of iron stores, vitamin B12 and folate. In addition, gastrointestinal evaluation is recommended for most patients with iron-deficiency anaemia. On the other hand, BS is a long-lasting inflammatory stimulus in itself and entails a reduction of the gastric capacity and/or exclusion from the gastrointestinal tract which impair nutrients absorption, including dietary iron. Chronic gastrointestinal blood loss and iron-losingenteropathy may also contribute to iron deficiency after BS. Perioperative anaemia has been linked to increased postoperative morbidity and mortality and decreased quality of life after major surgery, whereas treatment of perioperative anaemia, and even haematinic deficiency without anaemia, has been shown to improve patient outcomes and quality of life. However, long-term follow-up data in regard to prevalence, severity, and causes of anaemia after BS are mostly absent. Iron supplements should be administered to patients after BS, but compliance with oral iron is no good. In addition, once iron deficiency has developed, it may prove refractory to oral treatment. In these situations, IV iron (which can circumvent the iron blockade at enterocytes and macrophages) has emerged as a safe and effective alternative for perioperative anaemia management. Monitoring should continue indefinitely even after the initial iron repletion and anaemia resolution, and maintenance IV iron treatment should be provided as required. New IV preparations, such ferric carboxymaltose, are safe, easy to use and up to 1000 mg can be given in a single session, thus providing an excellent tool to avoid or treat iron deficiency in this patient population.

The pancreas is a retroperitoneal organ that releases water, bicarbonate and digestive enzymes by the main pancreatic duct (MPD) into the duodenum. Chronic pancreatitis (CP) is typically caused, in adults, by chronic alcohol abuse and, less frequently hypertriglyceridemia, primary hyperparathyroidism or cystic fibrosis. Exocrine dysfunction results in malabsorption of fat and subsequent steatorrhea. Damage to pancreatic endocrine function is a late finding in CP and results in hyperglycaemia or overt diabetes mellitus. Care of patients with CP principally involves management of pain. A significant change in the pain pattern or the sudden onset of persistent symptoms suggests the need to rule out other potential etiologies, including peptic ulcer disease, biliary obstruction, pseudocysts, pancreatic carcinoma, and pancreatic duct stricture or stones, then is important to establish a secure diagnosis. Management of pain should then proceed in a judicious stepwise approach avoiding opioids dependence. Patients should be advised to stop alcohol intake. Fat malabsorption and other complications may also arise. Management of steatorrhea should begin with small meals and restriction in fat intake. Pancreatic enzyme supplements can relieve symptoms and reduce malabsorption in patients who do not respond to dietary restriction. Enzymes at high doses should be used with meals. Treatment with acid suppression to reduce inactivation of the enzymes from gastric acid are recommended. Supplementation with medium chain triglycerides and fat soluble vitamin replacement may be required. Management of other complications (such as pseudocysts, bile duct or duodenal obstruction, pancreatic ascites, splenic vein thrombosis and pseudoaneurysms) often requires aggressive approach with the patient kept on total parenteral nutrition to minimize pancreatic stimulation.

OBJECTIVE: To assess the carotenoid status in young type I diabetic patients and its relationship to the glycaemic control of the disease. DESIGN: A follow-up study. SETTING: Hospital Universitario Puerta de Hierro, Health Area VI of Madrid (Spain). SUBJECTS: Forty-seven type I diabetic patients, followed for 2.5 years. INTERVENTIONS: Coinciding with physical examination and laboratory tests, serum levels of carotenoids were analysed by HPLC, and dietary intake of carotenoids was evaluated by a semiquantitative food frequency questionnaire and 3-day prospective dietary records. RESULTS: In type I diabetic patients, average intake, serum levels and correlations between diet and serum levels of carotenoids were comparable to those in reference non-diabetic groups. Between-subjects seasonal variations were observed for beta-cryptoxanthin intake and serum levels (higher in winter) and serum lycopene (higher in summer). Significant within-subjects seasonal changes were shown for dietary and serum beta-cryptoxanthin and serum beta-carotene. Serum carotenoids were unrelated to glycaemic control markers. Subjects with clinically acceptable glycaemic control showed lower lycopene intake than those with unacceptable control. Intake of carotenoids did not explain variance in insulin dose, fasting glycaemia, fructosamine or HbA1c. With the exception of lycopene, serum carotenoids were predicted by dietary intake, but in no case by fasting glycaemia, HbA1c or fructosamine. CONCLUSION: In type I diabetic patients, serum carotenoid concentrations and their variance are determined by dietary intake patterns, and are unrelated to the glycaemic control of the disease, as assessed by biochemical markers.

Laryngeal cancer constitutes and important problem from the nutritional point of view, both due to the effect of the tumor itself as due to the aggressive treatment to which the majority of these patients are subjected. To evaluate the incidence of nutritional support on the morbid-mortality and on the number of hospitalization days, we compare a group A of 61 patients diagnosed with laryngeal squamous cell carcinoma, who received treatment from the Department of Nutrition, with another, similar group B, who received a standard diet. a complete evaluation of the nutritional status was done (anthropometric biochemical and immunological parameters) one day prior to the surgery and two weeks after. The differences of age (61 vs 63 years), cigarette smoking (31 vs 34), excessive alcohol ingestion (34 vs 29), location of the tumor and type of surgery, were not significant. The nutritional treatment used in group A was enteral nutrition by means of a 12-F polyurethane naso-gastric tube, while in group B it was the ground up culinary diet through a large caliber naso-gastric tube. There were no significant differences in the mortality (1/0) or in the surgical complications (9/10); nevertheless, the average number of hospital days was clearly lower in group A (18 days) compared to group B (24 days) (p < 0.005). The evolution of the evaluation parameters of the nutritional status was analyzed, as well as the administered dietary formulae, added medication, and the complications of the technique. Regulated nutritional support may contribute to the decrease of the hospitalization period of patients operated on for laryngeal cancer.

The objective of the present study is to evaluate the effects of peripheral parenteral nutrition (PNN) in a homogeneous group of patients who had not had surgery, and to determine whether the deterioration of the nutritional state can be avoided while keeping the advantages of the administration of a peripheral route. We have included 7 patients (4 male and 3 female) with an acute episode of inflammatory bowel disease (IBD). Each received 1780 kcal/day (1500 non-protein kcal 66% as fats, and 33% as glucose), with a kcal/g of N ratio of 160 by means of the preparation technique of "all in one". The anthropometric parameters: initial and final weight (58.5 +/- 12 vs. 57.3 +/- 11); triceps skin fold (14.1 +/- 4 vs. 14.1 +/- 4), and mean circumference of the arm (25.1 +/- 3 vs. 25.0 +/- 3), did not give any significant differences during the treatment period. In the biochemical data there were no significant differences either, except for the final level of serum albumin (3.44 +/- 0.28), which was significantly higher than the initial value (3.11 +/- 0.38) (p < 0.05). The mean duration of the treatment was 12 days (range 6-18). There was no case of phlebitis.(ABSTRACT TRUNCATED AT 250 WORDS)
