Long-term follow-up of continuous flow left ventricular assist devices: complications and predisposing risk factors.

Purpose: To assess LVAD complications and their overall effect on mortality and determine factors associated with development of early and long-term complications.

Methods: A retrospective cohort study of patients who underwent continuous flow LVAD placement between January 1, 2000 and November 30, 2013 was performed. The incidence of complications (sepsis or bacteremia, driveline infections, gastrointestinal bleeding, pump thrombosis, cerebrovascular accidents and anemia requiring transfusion) was collected and logistic regression and Cox proportional hazards analyses were performed.

Impact of sequencing of postmastectomy radiotherapy and breast reconstruction on timing and rate of complications and patient satisfaction.

Purpose: There are few long-term studies of how the sequencing of postmastectomy radiotherapy (PMRT) and breast reconstruction (BR) affects the time to development of complications or patient satisfaction with BR. We therefore studied this issue.

Methods And Materials: One hundred thirteen women who underwent BR at Beth Israel Deaconess Medical Center (Boston, MA) from 1999-2006 and also received PMRT were included.

Postmastectomy radiation therapy and breast reconstruction: an analysis of complications and patient satisfaction.

The indications for postmastectomy radiotherapy (PMRT) have expanded over the past decade. This study examines PMRT and reconstruction compared with a control group without radiotherapy. There were 919 reconstructed breasts identified (1999-2006) and separated into 3 groups: mastectomy with PMRT before reconstruction (n = 57), immediate reconstruction then PMRT (n = 59), and reconstruction without PMRT (n = 665).

2-Chloro-3-(4-chloro-benzamido)-1,4-naphthoquinone.

The naphthoquinone ring is almost perpendicular [dihedral angle 71.02 (3)°] to the phenyl group of the title compound, C(17)H(9)Cl(2)NO(3), while the dihedral angle between the amide group and the 4-chloro-phenyl ring is 21.9 (2)°.

N-(3-Bromo-1,4-dioxo-1,4-dihydro-2-naphth-yl)-2-chloro-N-(2-chloro-benzoyl)benzamide.

The title compound, C(24)H(12)BrCl(2)NO(4), was synthesized from 2-amino-3-bromo-1,4-naphthoquinone and 2-chloro-benzoyl chloride. The crystal structure shows that each of the chloro-phenyl rings is inclined at about 60° to the naphthoquinone ring system. The two chloro-phenyl rings adopt a conformation that ensures that chlorine substituents are anti so as to reduce electronic repulsion.
