Occurrence and determinants of poor response to short-term pre-operative erythropoietin treatment.
This study aimed to explore the occurrence and determinants of poor response to short-term pre-operative erythropoietin treatment and the effect of such poor response on transfusion in total hip arthroplasty patients. ⋯ Use of angiotensin II receptor antagonists and vitamin K antagonists, and having a high BMI were determinants of poor response to short-term pre-operative erythropoietin treatment in total hip arthroplasty patients. Poor responders had a higher risk for perioperative blood transfusion.

ReviewNew hypothesis of chronic back pain: low pH promotes nerve ingrowth into damaged intervertebral disks.
The pathogenesis of low back pain is still elusive. Here, we proposed a new hypothesis that low pH is a possible cause of the development and progression of low back pain. ⋯ The inflammation response, evoked by the dorsal root ganglia, changes the delicate nutrient balance in the nucleus, resulting in a vicious cycle and leading to choronic back pain. Our hypothesis may explain many of the available clinical and experimental data on low back pain, thus it may help elucidate the pathogenesis of low back pain and improve clinical management.

What determines immediate use of invasive ventilation in patients with COPD?
The choice between non-invasive ventilation (NIV) and invasive ventilation in patients with an acute exacerbation of chronic obstructive pulmonary disease (AECOPD) may be irrational. The aim of this study was to examine those patient characteristics, and circumstances deemed important in the choice made between NIV and invasive ventilation in the intensive care unit (ICU). ⋯ Factors other than those deemed most important in guidelines appear to have an inappropriate influence on the choice between NIV and immediate intubation in AECOPD in the ICU. These factors must be identified to further increase the appropriate use of NIV.

Case ReportsCardiac arrest during sulprostone administration--a case report.
Sulprostone, a synthetic prostaglandin analogue with potent uterotonic action, has been shown to have a low complication rate in a large series. We present a case of cardiac arrest in a parturient after Caesarean section during continuous infusion of intravenous sulprostone administered for atonic post-partum haemorrhage. She had cardiopulmonary resuscitation for 25 min before spontaneous circulation returned. The sequence of events, the results of investigations carried out during the intensive care unit stay, and the presence of multiple cardiovascular risk factors, suggest that sulprostone caused coronary spasm, bradycardia, and subsequent asystole, similar to other cases described in the literature.

An inhaled tumor necrosis factor-alpha-derived TIP peptide improves the pulmonary function in experimental lung injury.
The lectin-like domain of TNF-α enhances the fluid clearance across the alveolar barrier. For experimental purposes, the lectin-like domain can be mimicked by a synthetic peptide representing the TIP-motif of TNF-α. The present study aims to assess the acute effect of TIP on the pulmonary function in a porcine model of acute respiratory distress syndrome (ARDS). ⋯ The inhalation of TIP induces an amelioration of clinical surrogate parameters of the lung function in a porcine lung injury model. By mimicking the lectin-like domain, the synthetic TIP peptide AP301 is an innovative approach as supportive therapy in ARDS.
