Safety profile and outcome after ultrasound-guided suprainguinal fascia iliaca catheters for hip fracture: a single-centre propensity-matched historical cohort study.

Purpose: Peripheral nerve blocks improve analgesia following hip fracture; however, there are little published data on safety and outcomes of continuous regional anesthetic techniques. Our institution offers pre- and perioperative, anesthesiologist-delivered ultrasound-guided suprainguinal fascia iliaca catheters (FICs) to patients with hip fracture. We aimed to document the safety profile of this technique and establish whether there are any significant clinical benefits in outcomes measured by the UK National Hip Fracture Database.

Microbial perchlorate reduction with elemental sulfur and other inorganic electron donors.

ClO(4)(-) has recently been recognized as a widespread contaminant of surface and ground water. This research investigated chemolithotrophic perchlorate reduction by bacteria in soils and sludges utilizing inorganic electron-donating substrates such as hydrogen, elemental iron, and elemental sulfur. The bioassays were performed in anaerobic serum bottles with various inocula from anaerobic or aerobic environments.

Chemolithotrophic perchlorate reduction linked to the oxidation of elemental sulfur.

Perchlorate (ClO(4)(-)) contamination of ground and surface water has been recently recognized as a widespread environmental problem. Biological methods offer promising perspectives of perchlorate remediation. Facultative anaerobic bacteria couple the oxidation of organic and inorganic electron-donating substrates to the reduction of perchlorate as a terminal electron acceptor, converting it completely to the benign end-product, chloride.

In-flight transfusion of packed red blood cells on a combat search and rescue mission: a case report from operation enduring freedom.

Injuries on the battlefield can occur far from the nearest medical treatment facility. This is especially likely for downed pilots and special operations personnel. Some of these injuries lead to significant blood loss requiring transfusion.
