A prospective randomized study was performed to evaluate the use of a urinary luteinizing hormone (LH) detection kit with 1 insemination as compared with 2 alternate day inseminations with timing ...based on previous cycle length and basal body temperature changes. The study involved 60 patients who underwent a total of 264 therapeutic donor insemination cycles using cryopreserved semen specimens. Patients alternated LH-kit timed cycles with cycles timed by non-LH methods for a total of 6 cycles or until pregnancy was achieved. Fecundability rates were 12.3% for LH-kit cycles and 5.3% for non-LH method cycles. The difference in outcome was not statistically significant. However, when the LH kit plus 1 insemination was compared with 2 inseminations timed by conventional methods, there appeared to be a distinct monetary and time expenditure advantage. These findings suggest that sufficient advantage may be derived from use of an LH kit to recommend its use on a routine basis for the timing of therapeutic donor insemination.
A 69-year-old man developed an embolus to his right femoral artery 24 h following the insertion of an implantable cardioverter defibrillator (ICD), with multiple shocks administered in the early ...postoperative period. He had nonobstructive hypertrophic cardiomyopathy with normal left ventricular function and no evidence of left atrial or ventricular thrombus seen on pre- or postoperative transthoracic echocardiography. There was no evidence of atrial fibrillation documented before or after implantation of the device. He had no other known risk factors for thromboembolic disease. Thromboembolic phenomena as a complication of ICD use have been described but arterial emboli believed related to ICD shocks have not been reported in patients without impaired systolic function.
Stunned by the implications of Colage's analysis of the cultural activation of the brain's Visual Word Form Area and the potential role of cultural neural reuse in the evolution of biology and ...culture, the authors build on his work in proposing a context for the first rudimentary hominin moral systems. They cross-reference six domains: neuroscience on sleep, creativity, plasticity, and the Left Hemisphere Interpreter; palaeobiology; cognitive science; philosophy; traditional archaeology; and cognitive archaeology's theories on sleep changes in Homo erectus and consequences for later humans. The authors hypothesize that the human genome, when analyzed with findings from neuroscience and cognitive science, will confirm the evolutionary timing of an internal running monologue and other neural components that constitute moral decision making. The authors rely on practical modern philosophers to identify continuities with earlier primates, and one major discontinuitysome bright white moral line that may have been crossed more than once during the long and successful tenure of Homo erectus on Earth.

A 35-year-old woman had infective endocarditis and an aneurysm of the anterior mitral leaflet. The patient was managed conservatively and the mitral valve aneurysm remained stable over 3 years. ...Two-dimensional, color flow Doppler, and magnetic resonance images of the aneurysm are presented and features of mitral valve aneurysms are discussed. Conservative management of mitral valve aneurysms with careful follow-up is an acceptable approach.
