Medicosurgical management of deep wound infections after thoracolumbar instrumentation: risk factors of poor outcomes.

Background: Surgical site infection (SSI) after thoracolumbar osteosynthesis is a common complication. Its management relies on surgical revision and antibiotic therapy, but treatment failure is not uncommon. The aim of our study was to assess the frequency of SSI management failure and its risk factors.

Patient-centeredness to anticipate and organize an end-of-life project for patients receiving at-home palliative care: a phenomenological study.

Background: The development of end-of-life primary care is a socio-medical and ethical challenge. However, general practitioners (GPs) face many difficulties when initiating appropriate discussion on proactive shared palliative care. Anticipating palliative care is increasingly important given the ageing population and is an aim shared by many countries.

Influence of Obesity on Access-Related Complications During Anterior Lumbar Spine Interbody Fusion.

Objective: The anterior lumbar spine approach has gained in popularity in recent years, but the associated access-related complications for obese patients have not been clearly established. This study aimed to analyze the relationship between obesity or overweight and the safety of the anterior lumbar spine approach.

Methods: Eighty-four consecutive patients admitted for lumbar spine surgery by anterior approach between 2011 and 2014 were included.

Flavor preference conditioning as a function of fat source.

Rats learn to prefer foods based, in part, on postingestive nutrient actions. This study compared the effectiveness of intragastric (IG) infusions of fat emulsions which varied in their fatty acid composition (chain length and saturation) to condition preferences for flavored saccharin solutions. In Experiment 1, food-restricted rats were trained (30 min/day) with one flavor (CS+CO) paired with IG corn oil (CO) and a second flavor (CS+MCT) paired with IG medium chain triglyceride (MCT); the fats were prepared as isocaloric emulsions.

Effects of exogenous ammonia or free amino acids on proteolytic activity and protein breakdown products in Streptococcus bovis, Prevotella albensis, and Butyrivibrio fibrisolvens.

We studied in details the ammonia or free amino acids (AA) effects on proteolytic activity of three ruminal bacteria: enzymatic activities and protein breakdown products were measured at the end of the exponential growth phase. In Streptococcus bovis the simultaneous uptake of ammonia and probably small peptides induced a decline in total proteolytic activity as a result of changes in endopeptidasic activities. With free AA, the tendency for the endopeptidasic activities to specialise was more evident and the total proteolytic activity decreased too.
