ABSTRACT
La detección de la desnutrición hospitalaria continúa de plena actualidad en la literatura médica y, a pesar de que desde hace dos décadas dejó de ser un tema novedoso, constituye un elemento recurrente en la bibliografía y motivo de abordajes monográficos en congresos y reuniones científicas.

BACKGROUND: The consumption of orange juice may lead to reduced oxidative stress and may enhance the antioxidant defense system. OBJECTIVE: The aim was to evaluate the effects of the intake of orange juice containing either normal (NPJ) or high (HPJ) concentrations of polyphenols (299 and 745 mg/d, respectively) on the antioxidant defense system, oxidative stress biomarkers, and clinical signs of metabolic syndrome in 100 nonsmoking subjects who were either overweight or obese. METHODS: A randomized, double-blind crossover study was conducted over two 12-wk periods with a 7-wk washout period. The effects on enzymatic and nonenzymatic blood antioxidant defense systems, urinary and plasma oxidative stress biomarkers, and clinical signs of metabolic syndrome were evaluated before and after an intervention with both of the orange juices. Paired t tests and linear mixed-effects models were used to evaluate the effects of juice, time, and interactions. RESULTS: The intake of either NPJ or HPJ led to a decrease in urinary 8-hydroxy-2'-deoxyguanosine (NPJ: 935 ± 134 to 298 ± 19 ng/mg creatinine; HPJ: 749 ± 84 to 285 ± 17 ng/mg creatinine), 8-iso-prostaglandin F2α (NPJ: 437 ± 68 to 156 ± 14 ng/mg creatinine; HPJ: 347 ± 43 to 154 ± 13 ng/mg creatinine), erythrocyte catalase, and glutathione reductase activities. A decrease was also observed in body mass index, waist circumference, and leptin (all P < 0.05). The NPJ intervention decreased systolic and diastolic blood pressures (systolic blood pressure: 128 ± 1 to 124 ± 2 mm Hg; diastolic blood pressure: 79 ± 1 to 76 ± 1 mm Hg), whereas the HPJ intervention increased erythrocyte superoxide dismutase (SOD) activity (17.7 ± 1.5 to 23.1 ± 1.7 U/mg hemoglobin). CONCLUSIONS: Our results show that the consumption of either NPJ or HPJ protected against DNA damage and lipid peroxidation, modified several antioxidant enzymes, and reduced body weight in overweight or obese nonsmoking adults. Only blood pressure and SOD activity were influenced differently by the different flavanone supplementations. This trial was registered at clinicaltrials.gov as NCT01290250.

Home parenteral nutrition (HPN) improves the quality of life of the patients although it has complications. Catheter-related infections and mechanical complications are the most frequent ones. We report the case of endocarditis over catheter in a man suffering from short bowel and receiving HPN. The special features of the case are firstly the catheter was a remaining fragment on the right atrial and secondly the infection was caused by Trichoderma longibrachiatum, an isolated fact regarding this pathology so far. Conventional surgery was applied to take the catheter out. Staphylococcus epidermidis, Ochrobactrum anthropi and Trichoderma longibrachiatum were isolated from the surgical specimen. The extraction of the infected catheter along with antibiotic therapy led to the complete recovery of the subject. Ochrobactrum anthropi and Trichoderma longibrachiatum are unusual microorganisms but they are acquiring more relevance. Although there is no agreement about intravascular retained catheter management, the most recommended approach consists on monitoring them and removing the device in case of complications.
La modalidad domiciliaria de la nutrición parenteral (NPD) mejora la calidad de vida de los pacientes, pero tiene complicaciones como infecciones asociadas a catéter (IAC) y complicaciones mecánicas. Presentamos el caso de un paciente con NPD por intestino corto que desarrolla una endocarditis sobre catéter con matices especiales: asentar sobre un catéter abandonado en aurícula derecha y tratarse de una infección con participación de un microorganismo no descrito hasta el momento en esta patología, Trichoderma longibrachiatum. El catéter se extrajo mediante cirugía convencional. En la pieza quirúrgica se aislaron Staphylococcus epidermidis, Ochrobactrum anthropi y Trichoderma longibrachiatum. Combinando el tratamiento antibiótico y la eliminación del foco infeccioso se consiguió la recuperación completa. Ochrobactrum anthropi y Trichoderma longibrachiatum son microorganismos poco habituales, pero que cada vez adquieren mayor relevancia. Aunque no existe acuerdo en el manejo de los catéteres intravasculares "abandonados", es recomendable el seguimiento y eliminarlos en caso de complicación.
