Total hip arthroplasty (THA), hemiarthroplasty (HA), and open reduction internal fixation (ORIF) are treatment options for femoral neck fractures. However, the optimal surgical treatment remains unclear. The present study aimed to describe the 30-d postoperative outcomes of THA, HA, and ORIF among patients aged ≥65 y with femoral neck fractures within a national surgical database. ⋯ No differences were found in the 30-d mortality rates among the ORIF, HA, and THA groups. ORIF and HA resulted in a lower likelihood of developing respiratory complications than THA.

This study tested the hypothesis that blockade of the pH-regulatory protein, Na+/H+ exchanger (NHE1) during prolonged hemorrhagic shock can protect against whole-body ischemia-reperfusion injury, resulting in improved neurological outcomes. ⋯ In this study, NHE1 inhibition with BIIB513 improved vital organ blood flow, prevented the development of metabolic acidosis during prolonged hypovolemia, and facilitated the hemodynamic response to fluid resuscitation, resulting in increased survival and normal neurological outcomes.

Comparative Study
Agreement of cardiac output measurement between pulse contour analysis and thermodilution in various body positions: a porcine study.
We elucidated the effects of various body positions on the agreement of cardiac output (CO) measurement between pulse contour analysis with the PiCCO monitor and thermodilution with pulmonary artery catheterization. ⋯ The mean CO measured by pulse contour analysis and thermodilution did not agree well in various body positions. Moreover, the measurements tended to trend differently in response to positional changes. For paired CO ≤6 L/min, however, the between-methods agreement and the trending ability improved significantly.

The optimal management of colon injury patients requiring damage control laparotomy (DCL) is controversial. The objective of this study was to assess the safety of colonic resection and anastomosis versus fecal diversion in trauma patients requiring DCL. ⋯ Outcomes after colonic injury in the setting of DCL were similar regardless of the surgical management strategy. Based on these findings, a strategy of diversion over anastomosis cannot be strongly recommended.

We assessed the short-term outcomes and predictors of 30-d mortality in patients requiring temporary, peripheral extracorporeal membrane oxygenation (ECMO) for postcardiotomy cardiac failure. ⋯ ECMO therapy provides a valuable therapeutic strategy for postcardiotomy myocardial failure but is still limited by high complication rates with fewer than 30% of patients discharged from the hospital. Patient age appears to be an essential preoperative predictor for mortality, and the blood lactate level is a relevant marker for the assessment of efficient ECMO support.
