Malnutrition as assessed by nutritional risk index is associated with worse outcome in patients admitted with acute decompensated heart failure: an ACAP-HF data analysis

Malnutrition is common at hospital admission and tends to worsen during hospitalization. This controlled population study aimed to determine if serum albumin or moderate and severe nutritional depletion by Nutritional Risk Index (NRI) at hospital admission are associated with increased length of hospital stay (LOS) in patients admitted with acute decompensated heart failure (ADHF). Serum albumin levels and lymphocyte counts were retrospectively determined at hospital admission in 1740 consecutive patients admitted with primary and secondary diagnosis of ADHF. The Nutrition Risk Score (NRI) developed originally in AIDS and cancer populations was derived from the serum albumin concentration and the ratio of actual to usual weight, as follows: NRI = (1.519 × serum albumin, g/dL) + {41.7 × present weight (kg)/ideal body weight(kg)}. Patients were classified into four groups as no, mild, moderate or severe risk by NRI. Multiple logistic regressions were used to determine the association between nutritional risk category and LOS

Regeneración de árboles tropicales e implicaciones para el manejo de bosques naturales

El reclutamiento exitoso desde semillas en bosques neotropicales implica una secuencia de etapas. La disponibilidad del polen y recursos consumibles por los árboles maternales puede limitar el número de semillas producidas. La dispersión de semillas a un sitio determinado puede ser limitada por la densidad o la dispersión de árboles frutales, o por el agrupamiento impuesto por los procesos de dispersión de semillas. El establecimiento de semillas dispersadas puede ser limitado por la mortalidad debida a enemigos naturales, por ejemplo depredadores de semillas y herbivoros, o por factores abióticos tales como la disponibilidad de agua, nutrientes y luz. Como la limitación impuesta por estas etapas puede verse afectada por la explotación forestal selectiva, es necesario investigar el efecto de las prácticas selvícolas sobre cada etapa en la dinámica del bosque

The incidence and possible relevance of Bence-Jones protein in the sera of patients with multiple myeloma

We present results showing that the detectable incidence of Bence-Jones protein in the sera of patients with multiple myeloma is equivalent to the highest detectable incidence of Bence-Jones protein in highly concentrated urine when tested by immuno-isoelectric focusing. In a series of 25 multiple myeloma patients, immuno-isoelectric focusing showed the incidence of Bence-Jones proteinemia to be 68% compared with a detectable incidence of Bence-Jones proteinuria of 32-64% by immunoelectrophoresis and immuno-isoelectric focusing depending upon the urine concentration factor. In view of the variability of factors governing urinary Bence-Jones protein levels, such as renal catabolism, reabsorption and losses during concentration, we suggest that monitoring of serum Bence-Jones protein by immuno-isoelectric focusing should be carried out in conjunction with measurements of urinary Bence-Jones protein in multiple myeloma
