Appetite disorders in cancer patients: Impact on nutritional status and quality of life.

Cancer patients are at high risk of malnutrition due to several symptoms such as lack of appetite. The aim of this study was to determine the prevalence of different appetite disorders in cancer patients and their influence on dietary intake, nutritional status, and quality of life. We conducted a cross-sectional study of cancer patients at risk of malnutrition. Nutritional status was studied using Subjective Global Assessment, anthropometry, and grip strength. Dietary intake was evaluated with a 24-h recall, and patients were questioned about the presence of changes in appetite (none, anorexia, early satiety, or both). Quality of life was measured using EORTC-QLQ-C30. Multivariate analysis was performed using linear regression. 128 patients were evaluated. 61.7% experienced changes in appetite: 31% anorexia, 13.3% early satiety, and 17.2% both. Appetite disorders were more common in women and with the presence of cachexia. The combination of anorexia and satiety resulted in a lower weight and BMI. However, there were no significant effects on energy or macronutrient intake among different appetite alterations. Patients with a combination of anorexia and early satiety had worse overall health perception, role function, and fatigue. Appetite disorders are highly prevalent among cancer patients at risk of malnutrition. They have a significant impact on nutritional status and quality of life, especially when anorexia and early satiety are combined.

Long-term outcome of multimodal therapy for giant prolactinomas

Giant prolactinomas are rare tumors characterized by their large size, compressive symptoms, and extremely high prolactin secretion. The aim of this study is to describe our experience with a series of 16 giant prolactinomas cases in terms of clinical presentation, therapeutic decisions, and final outcomes. Retrospective analysis of adult patients diagnosed with giant prolactinomas at the endocrine departments of three university tertiary hospitals. We included 16 patients (43.7 % women); mean age at diagnosis: 42.1 ± 21 years. The most frequent presentation was compressive symptoms. The delay in diagnosis was higher in women (median of 150 months vs. 12 in men; p = 0.09). The mean maximum tumor diameter at diagnosis was 56.9 ± 15.5 mm, and mean prolactin levels were 10,995.9 ± 12,157.8 ng/mL. Dopamine agonists were the first-line treatment in 11 patients (mean maximum dose: 3.9 ± 3.2 mg/week). Surgery was the initial treatment in five patients and the second-line treatment in six. Radiotherapy was used in four cases. All patients but one, are still with dopamine agonists. After a mean follow-up of 9 years, prolactin normalized in 7/16 patients (43.7 %) and 13 patients (81 %) reached prolactin levels lower than twice the upper limit of normal. Mean prolactin level at last visit: 79.5 ± 143 ng/mL. Tumor volume was decreased by 93.8 ± 11.3 %, and final maximum tumor diameter was 18.4 ± 18.8 mm. Three patients are actually tumor free. Giant prolactinomas are characterized by a large tumor volume and extreme prolactin hypersecretion. Multimodal treatment is frequently required to obtain biochemical and tumor control.

Beneficios de la terapia con infusión subcutánea continua de insulina en pacientes diabéticos tipo 1 que presentan gran variabilidad glucémica

BACKGROUND Hypoglycemia limits the efficacy of intensive insulin therapy, especially in patients with great glucose variability. The extent to which continuous subcutaneous insulin infusion (CSII) overcomes this limitation is unclear. Our aim was to determine whether CSII is helpful for decreasing glucose variability and hypoglycemia, mainly in patients with the greatest variability. METHOD Twenty-four patients with type 1 diabetes wore a continuous glucose monitoring system sensor for three days before starting therapy with CSII and 6 months later. Glucose variability (SD, MAGE, M) and hypoglycemia duration (area under the curve (AUC) <70mg/dL) were compared in all patients and in those with the greatest MAGE (highest quartile). RESULTS At 6 months, a decreased glucose variability was seen, as measured by MAGE, M, and SD (median: -28mg/dL (interquartile range, -48 to 1), p=0.03; -22(-40 to 0), p=0.04; -11(-23 to 0), p=0.009; respectively). Patients with the greatest initial glucose variability (MAGE quartile 4) showed a greater decrease in both MAGE (-47mg/dL (-103 to -34) vs -20 (-36 to 17), p=0.01) and AUC <70 (-10.7mg/dL x day (-15 to 0) vs -1.1 (-4.7 to 3.8), p=0.03) as compared to all others. Patients with longer initial hypoglycemia (AUC quartile 4) achieved a greater reduction in AUC <70 (-9.7mg/dL x day(-15 to -6.5) vs -0.08 (-2.9 to 3.8), p=0.003). A correlation was found between ΔMAGE-ΔAUC (r 0.4, p=0.03). CONCLUSIONS During CSII, glucose variability significantly decreased, especially in patients with the greatest initial variability. Hypoglycemia was also markedly less in patients with greater variability, with the greatest reduction occurring in those who experienced more marked hypoglycemia with CSII.

Severe hypertension and hypokalemia as first clinical manifestations in ectopic Cushing's syndrome

Ectopic ACTH production occurs in about 10% of all cases of Cushings syndrome, and about 25% of cases of ACTH-dependent Cushings syndrome. Diverse tumor types are able to produce ACTH ectopically, including small cell lung carcinoma. Ectopic ACTH secretion by malignant neoplasm has been reported to have earlier and more aggressive metabolic effects. We report a 59-year-old male patient with severe hypertension, metabolic alkalosis and hypokalemia as the first clinical manifestations of an ACTH-secreting small cell lung carcinoma, although the typical phenotypic features of Cushings syndrome were not present. Ectopic Cushings syndrome should always be ruled out in patients with severe hypertension and hypokalemia.

Consumption of Low-Fat Dairy Products and Energy and Protein Intake in Cancer Patients at Risk of Malnutrition

Current nutritional guidelines encourage the reduction of fat intake from animal sources like dairy products. The aim was to determine whether the consumption of low-fat dairy is related to poorer dietary intake and nutritional status in cancer patients at risk of malnutrition. This cross-sectional included patients with solid or hematological malignancies at risk of malnutrition. Nutritional status was studied using Subjective Global Assessment, anthropometry, and grip strength. Dietary intake was evaluated with a 24-h recall and dairy consumption with a structured questionnaire. Seventy-four patients were recruited; 71.6% males of 64.8 yr, most with gastrointestinal malignancies. Only 37.8% consumed whole milk, and 61.4% consumed whole yogurt. Reasons for consumption of low-fat dairies were healthy diet (58.0%), hypercholesterolemia (20.0%), and digestive intolerance (10.0%). There were similar rates of malnutrition according the type of dairy (whole 60.9% vs. low-fat 66.7%, P = 0.640). Low-fat dairies were related to a reduction in energy (whole 1980.1 kcal vs. low-fat 1480.9, P = 0.007) and protein intake (whole 86.0 g vs. low-fat 63.0 g, P = 0.030).

ECONOMIC BURDEN OF HOME ARTIFICIAL NUTRITION IN THE HEALTH AREA OF SANTIAGO DE COMPOSTELA.

INTRODUCTION home artificial nutrition (HAN) is a growing therapy, but the absence of obligatory registries complicates the calculation of its real economic burden. The aim of this study was to assess the state and economic impact of HAN in our health area. METHODS an observational, prospective study was designed to calculate the cost of nutritional formulas and materials in patients who initiated HAN in the nutrition unit during a year. RESULTS we included 573 new patients with HAN during the study period, 60% of whom were treated with oral supplements. The median daily cost of oral HAN was 3.65 (IQR 18.63) euros compared to a cost of 8.86 (IQR 20.02) euros for enteral-access HAN. The daily expenditure per 1 000 kcal of diet was higher for patients on oral HAN than for patients with tubes (5.13 vs. 4.52 euros, p < 0.001). The median cost of the complete HAN treatments during the study period was also calculated (186.60 euros and 531.99 euros for oral and tube HAN, respectively). The total estimated cost for all patients who initiated HAN in the study period was around one million euros. CONCLUSIONS HAN represented an important economic burden in our health area, but the estimated daily cost of HAN was moderate, probably because of the high frequency of oral HAN, the adjusted treatments, and the centralized dispensation by the hospital pharmacy.

Spontaneous remission of acromegaly: apoplexy mimicking meningitis or meningitis as a cause of apoplexy?

Pituitary apoplexy is a rare but potentially life-threatening clinical syndrome characterized by ischemic infarction or hemorrhage into a pituitary tumor. The diagnosis of pituitary tumor apoplexy is frequently complicated because of the nonspecific nature of its signs and symptoms, which can mimic different neurological processes, including meningitis. Several factors have been associated with apoplexy, such as dopamine agonists, radiotherapy, or head trauma, but meningitis is a rarely reported cause. We describe the case of a 51-year-old woman with acromegaly due to a pituitary macroadenoma. Before surgical treatment, she arrived at Emergency with fever, nausea, vomiting and meningismus. Symptoms and laboratory tests suggested bacterial meningitis, and antibiotic therapy was initiated, with quick improvement. A computerized tomography (CT) scan at admission did not reveal any change in pituitary adenoma, but a few weeks later, magnetic resonance imaging (MRI) showed data of pituitary apoplexy with complete disappearance of the adenoma. Currently, her acromegaly is cured, but she developed hypopituitarism and diabetes insipidus following apoplexy. We question whether she really experienced meningitis leading to apoplexy or whether apoplexy was misinterpreted as meningitis. In conclusion, the relationship between meningitis and pituitary apoplexy may be bidirectional. Apoplexy can mimic viral or bacterial meningitis, but meningitis might cause apoplexy, as well. This fact highlights the importance of differential diagnosis when evaluating patients with pituitary adenomas and acute neurological symptoms.

Impact of kitchen organization on oral intake of malnourished inpatients: A two-center study

AIM To determine the impact of the type of hospital kitchen on the dietary intake of patients. METHODS A cross-sectional, two-centre study, of cooking in a traditional kitchen (TK) and in a chilled kitchen (CK). Subjective global assessment (SGA) was used for nutritional diagnosis. Before study start, a dietician performed a nutritional assessment of the menus of each hospital. All dishes were weighed upon arrival to the ward and at the end of the meal. RESULTS 201 and 41 patients from the centres with TK and CK respectively were evaluated. Prevalence of malnutrition risk was 50.2% at the hospital with TK and 48.8% at the hospital with CK (p=0.328). Forty-eight and 56 dishes were nutritionally evaluated at the hospitals with TK and CK respectively. Intake analysis consisted of 1993 and 846 evaluations in the hospitals with TK and CK respectively. Median food consumption was 76.83% at the hospital with TK (IQR 45.76%) and 83.43% (IQR 40.49%) at the hospital with CK (p<0.001). Based on the prevalence of malnutrition, a higher protein and energy intake was seen in malnourished patients from the CK as compared to the TK hospital, but differences were not significant after adjustment for other factors. CONCLUSIONS Cooking in a chilled kitchen, as compared to a traditional kitchen, may increase energy and protein intake in hospitalized patients, which is particularly beneficial for malnourished patients.

Abordaje nutricional del enfermo oncohematológico: best-practice en España

Los datos del estudio PREDYCES® nos revelaron que en Espana la desnutricion relacionada con la enfermedad (DRE) afecta a uno de cada cuatro pacientes hospitalizados. Esta cifra aumenta hasta el 36,8% en los pacientes hematologicos. Se calcula que un 20% de los pacientes oncologicos muere por complicaciones relacionadas con la DRE. Nuestro grupo se planteo en 2011 comenzar la implantacion de un cribado nutricional en los servicios con mayor riesgo de DRE. La presente revision trata de describir todo el proceso que hemos seguido para mejorar la situacion nutricional en los pacientes ingresados en el Servicio de Hematologia del Complejo Asistencial Universitario de Leon (CAULE), mayoritariamente con diagnostico de neoplasias hematologicas. En un primer estudio piloto, detectamos una alta prevalencia de desnutricion, que tendio a aumentar durante la hospitalizacion. Ademas, solo el 8,3% los enfermos valorados recibieron algun tipo de soporte nutricional y no se estaban cubriendo sus necesidades ni caloricas ni proteicas, lo que se asociaba a un peor pronostico. Por este motivo, nos decidimos a implantar de manera sistematica un cribado y una intervencion nutricional adecuada, que comenzo en 2011 y que ha recibido el reconocimiento como Buena Practica del Sistema Nacional de Salud.

A short nutritional intervention in a cohort of hematological inpatients improves energy and protein intake and stabilizes nutritional status.

INTRODUCTION Oncohematological diseases are associated with an important prevalence of malnutrition. AIM Our aim is to determine if early recognition and treatment of malnourished hematological inpatients can improve their oral intake, nutritional status and reduce the length of hospital stay. METHODS Prospective 2-year study conducted in a cohort of hematology inpatients. Malnutrition Screening Tool (MST) was carried out on the first day of admission. Patients with a positive screening were recruited to have a complete nutritional evaluation and intervention, following usual clinical practice. Nutritional evaluation was repeated after one week. RESULTS Six hundred and seventeen hematological patients were screened (37.8% with positive screening). After one week, median diet intake increased from 80% to 90% (p < 0.001), and an increase of 407.36 Kcal (SD 679.37) and 17.58 g of protein (SD 31.97) was also achieved. More patients reached their energy and protein requirements (41.6 vs.% 63.3%, p = 0.009) and nutritional parameters remained stable. A trend to a lower stay (3.5 to 4.5 days less) was detected in the groups of patients who covered their needs. CONCLUSIONS The implementation of early malnutrition screening and short nutritional interventions improved energy and protein intake, increasing the percentage of patients who meet their requirements and avoiding deterioration of nutritional status.
