Pharmacokinetics and pharmacodynamics of piperacillin/tazobactam during high volume haemodiafiltration in patients with septic shock.
The purpose of the study was to evaluate the pharmacokinetics (PK) and pharmacodynamics (PD) of piperacillin and tazobactam during high-volume haemodiafiltration (HVHDF). ⋯ For bactericidal PK/PD target attainment piperacillin/tazobactam doses of 4/0.5 g every 8 h appear appropriate in septic shock patients with minimal residual renal function during HVHDF.

Review[Prehospitale analgesia in adults].
After securing vital function, treatment of pain is an important aspect in emergency medical care. Irrespective of the underlying disease or injury, pain is an important warning symptom of the body and the most common reason for an emergency alert notification. A patient assesses quality of care and success of prehospital care using the criteria of the extent of pain relief he experiences. ⋯ Above a grade of 4, therapeutic intervention should be initiated with the goal of reducing pain to reach a value of <4, or at least to achieve a reduction by 3 points. The choice of analgesics that can be meaningfully used in pre-hospital emergency medicine is limited. The emergency physician should be aware of available drugs and administration routes.

The Mechanism of Mitral Regurgitation Influences the Temporal Dynamics of the Vena Contracta Area as Measured with Color Flow Doppler.
In patients with mitral regurgitation (MR), the effective regurgitant orifice area can be estimated by measuring the vena contracta area (VCA). We hypothesize that the VCA has characteristic temporal dynamics related to the underlying mechanism of functional mitral regurgitation (FMR) versus degenerative mitral valve disease (DMVD). ⋯ VCA dynamics are governed by the mechanism of MR and are observed in FMR patients primarily as a biphasic temporal pattern compared with a monophasic temporal pattern in patients with DMVD.

Glucocorticoid receptor expression and binding capacity in patients with burn injury.
Burn injuries are associated with strong inflammation and risk of secondary sepsis which both may affect the function of the glucocorticoid receptor (GR). The aim of this study was to determine GR expression and binding capacity in leucocytes from patients admitted to a tertiary burn center. ⋯ GR expression and binding capacity are increased in most types of circulating leucocytes of severely burned patients on their admission to specialized burn care. If sepsis is present after 1 week, it is associated with higher GR expression in T lymphocytes and NK cells.

Pain can be modulated by contextual stimuli, such as emotions, social factors, or specific bodily perceptions. We presented painful laser stimuli together with body-related masochistic visual stimuli to persons with and without preferred masochistic sexual behavior and used neutral, positive, and negative pictures with and without painful stimuli as control. Masochists reported substantially reduced pain intensity and unpleasantness in the masochistic context compared with controls but had unaltered pain perception in the other conditions. ⋯ Masochists additionally showed negative correlations between the duration of interest in masochistic activities and activation of areas involved in motor activity and affective processing. We propose that the parietal operculum serves as an important relay station that attenuates the affective-motivational aspects of pain in masochists. This novel mechanism of pain modulation might be related to multisensory integration and has important implications for the assessment and treatment of pain.
