RESUMEN
In chronic kidney disease (CKD), the design of the parenteral nutrition (PN) regimen becomes more challenging where only individualized PN is appropriate, coupled with the increased risk of unintended interactions with diuretic therapy. In an effort to ensure safe therapy in the home, we assessed the physical stability of bespoke PN formulations intended for use in CKD in the simultaneous presence of Y-site compatibility of furosemide and torasemide. The patient's daily needs were determined based on both metabolic demands as well as the demand for fluids.Complete admixtures were subjected to physical stability analysis consisting of visual inspection, a validated light microscope method, pH measurement, zeta potential measurement, and characterization of oily globule size distribution. Y-site compatibility of furosemide and torasemide with the formulated admixtures was also performed.The total parenteral admixture was stable over 7 days at +4°C and 24âh at +25°C and compatible via the Y-line together with furosemide and torasemide over 12âh at +25°C.The stability assessment guarantees the safety and efficiency of home PN with loop diuretics therapy in CKD patients. This means that these patients do not need long hospitalization and they can be safely treated at home. Furthermore, this study proved that torasemide is the same safety diuretic as furosemide, which has a great impact on clinical practice.

La desnutrición es un problema médico frecuente de los pacientes oncológicos que impacta de forma negativa en la calidad de vida. El objetivo de este trabajo es analizar y dar respuesta a diferentes cuestiones relacionadas con el manejo nutricional de un paciente oncológico en la práctica clínica. Un grupo multidisciplinar de expertos en Oncología Médica, Endocrinología y Nutrición y Farmacia elaboró una lista de temas relacionados con el estado nutricional del paciente oncológico agrupados en 3 bloques: soporte nutricional, nutrición parenteral (NP) y NP domiciliaria (NPD). Se realizó una revisión de la literatura que incluyó artículos publicados en español, inglés y francés hasta abril de 2017. Este consenso destaca diferentes elementos clave que ayudarán a los médicos a normalizar el manejo del estado nutricional del paciente oncológico en la práctica clínica, estableciendo pautas comunes de indicación, monitorización, requerimientos nutricionales y vías de acceso a la NP
Malnutrition is a common medical problem in cancer patients with a negative impact on quality of life. The aim of this study was to address different issues related to nutritional management of cancer patients in clinical practice. A multidisciplinary group of experts in Medical Oncology, Pharmacy, and Endocrinology and Nutrition prepared a list of topics related to the nutritional status of cancer patients and grouped them into three blocks: nutritional support, parenteral nutrition (PN), and home PN (HPN). A literature review was made of articles published in Spanish, English and French until April 2017. This consensus emphasizes several key elements that help physicians standardize management of the nutritional status of cancer patients in clinical practice, and establishes common guidelines for indication, monitoring, nutritional requirements, and access routes to PN

BACKGROUND: Vitamin K supplementation improves bone health, and its absence might be associated with low bone mineral density (BMD). The authors aim to assess vitamin K supplementation practices in Canadian home parenteral nutrition (HPN) programs and their relationship with BMD. METHODS: This is a cross-sectional study of 189 patients from the Canadian HPN registry. RESULTS: All 189 patients studied received M.V.I.-12, which does not contain vitamin K. Of those, 41.3% were supplemented with 10 mg of intravenous vitamin K (VK+) weekly, whereas the others did not receive vitamin K except via lipid emulsion (VK-). Short bowel syndrome accounted for 69% of VK+ and 46% of VK- patients. On univariate analysis, VK+ patients had substantially lower body mass index (BMI) and received lower bisphosphonate infusion than did VK-patients. There were no statistically significant differences in HPN calcium or lipid content, liver function test results, age, sex, or reason for HPN between the 2 groups. Patients who were VK+ had higher lumbar spine T scores and hip T scores than did VK-patients. General linear modeling analysis, adjusted for BMI, age, PN magnesium, PN phosphate, PN calcium, and bisphosphonate as possible predictors of BMD, showed a trend toward better hip T scores (P = .063) for VK+ patients compared with VK- patients. CONCLUSION: In HPN patients supplemented with vitamin K, the trend toward a better hip BMD compared with no supplementation suggests a role for vitamin K in preserving BMD. This requires further study.

Intestinal failure is characterised by inability of the intestine to absorb sufficient nutrients to maintain the integrity and function of the body. This can be caused by malabsorption due to too short an intestine or an abnormality of the mucosa, or by a severe motility disorder. In addition to dietary measures, the prescription of total parental nutrition (TPN) at home is sometimes necessary. This treatment is a burden on the patient and the risk of complications must be reduced to a minimum. The risks of long-term parenteral nutrition can be limited and the quality of the provision of services can be increased if the co-ordination is in the hands of a centre for home parenteral nutrition. In the Netherlands there are two centres for home-TPN: the St Radboud University Medical Centre in Nijmegen and the University Medical Centre (AMC) in Amsterdam. In both children and adults, the most common indications are the short bowel syndrome and motility disorders. However, the syndromes that cause this are clearly different in the different age groups. Parenteral nutrition can be given for long periods of time. A large variety of complications can occur, related especially to the equipment or the nutrients. When the nutrition is given via a central venous catheter, then sepsis is a serious and possibly life-threatening complication. In case of administration via an arteriovenous shunt, thrombosis of the shunt is the most frequent problem. If the treatment by means of home-TPN fails, then transplantation of the small intestine should be considered.

The administration of a single mixture of the components of total parenteral nutrition (TPN) constitutes total nutritional admixture (TNA), the safety and efficacy of which in a variety of clinical settings have been confirmed by controlled trials. According to the nitrogen balance and stable isotope methods, TNA is as efficacious as the old system of three bottles with piggyback intravenous fat emulsion in maintaining body nitrogen mass, visceral protein, and liver function. Also, serum concentrations of electrolytes, trace elements, and vitamins can be maintained adequately using the TNA system. The other advantages are the timesaving to the nursing staff, with its hidden savings in cost; the avoidance of a peripheral catheter solely for the infusion of lipid emulsion in addition to the central catheter for TPN in hospitalized patients; and the facility of use in home nutrition programs. The ease of home use has resulted in a greater degree of patient compliance; thus patients receive a mixed-fuel system while avoiding the hazards of a piggyback infusion, with all its potential complications. Among the perceived disadvantages of TNA are a supposed higher frequency of catheter-related sepsis, a view based on in vitro studies that is not borne out by in vivo studies; catheter occlusion by precipitation of calcium salts; and enhanced ability to clear fat and thus fat tolerance with continuous infusion of lipids. Numerous studies have shown that these concerns are unwarranted.
