Blood Conservation in Total Hip Arthroplasty: Interim Analysis of the Tranexamic Acid Comparison in Hip Replacement (TeACH-R) Trial
Intravenous tranexamic acid (TEA) is used in total hip arthroplasty (THA) to reduce blood loss. Concern of increased thromboembolic risk has prompted the search for treatment alternatives. The Tranexamic Acid Comparison in Hip Replacement (TeACH-R) trial is a prospective randomized controlled trial comparing the efficacy of intravenous and topical TEA in reducing perioperative blood loss. For interim data analysis, 52 of the planned 144 participants had completed the initial phase of the TeACH-R trial. No significant differences were identified between the intravenous and topical TEA treatment arms for delta-hemoglobin (ΔHgb; 34.81±13.78 vs. 35.65±15.54 mg/dL; p=0.840), calculated blood loss (1548±509 vs. 1521±693 mL; p=0.873), or length of stay (55.0±11.44 vs. 54.5±20.1 hours; p=0.912). No participant required a blood transfusion or had a thromboembolic event postoperatively. Promising initial results support the use of topical TEA in THA, although therapeutic decisions should be made only once all data has been analyzed

Discovery of the Widest Very Low Mass Binary
We report the discovery of a very low mass binary system (primary mass <0.1
Msol) with a projected separation of ~5100 AU, more than twice that of the
widest previously known system. A spectrum covering the 1-2.5 microns
wavelength interval at R ~1700 is presented for each component. Analysis of the
spectra indicates spectral types of M6.5V and M8V, and the photometric distance
of the system is ~62 pc. Given that previous studies have established that no
more than 1% of very low mass binary systems have orbits larger than 20 AU, the
existence of such a wide system has a bearing on very low mass star formation
and evolution models.Comment: accepted ApJL, 4 page
Single Leptoquark Production at and Colliders
We consider single production of leptoquarks (LQ's) at and
colliders, for two values of the centre-of-mass energy,
GeV and 1 TeV. We find that LQ's which couple within the first
generation are observable for LQ masses almost up to the kinematic limit, both
at and colliders, for the LQ coupling strength equal to
. The cross sections for single production of - and
-generation LQ's at colliders are too small to be observable.
In collisions, on the other hand, -generation LQ's with
masses much larger than can be detected. However,
-generation LQ's can be seen at colliders only for
masses at most , making their observation more probable via the
pair production mechanism.Comment: plain TeX, 14 pages, 6 figures (not included but available on
