Induction of HIV-1-specific mucosal immune responses following intramuscular recombinant adenovirus serotype 26 HIV-1 vaccination of humans.

Background: Defining mucosal immune responses and inflammation to candidate human immunodeficiency virus type 1 (HIV-1) vaccines represents a current research priority for the HIV-1 vaccine field. In particular, it is unclear whether intramuscular immunization can elicit immune responses at mucosal surfaces in humans.

Methods: In this double-blind, randomized, placebo-controlled clinical trial, we evaluated systemic and mucosal immune responses to a candidate adenovirus serotype 26 (Ad26) vectored HIV-1 envelop (Env) vaccine in baseline Ad26-seronegative and Ad26-seropositive healthy volunteers.

Serologic response to hepatitis B vaccination among lung transplantation candidates.

Background: Optimal hepatitis B (HBV) vaccination strategies for lung transplantation (LT) candidates are not well established.

Methods: LT candidates with negative anti-HBs and anti-HBc antibody titers at baseline who received standard-dose HBV vaccination (Recombivax-HB 10 mcg/mL or Engerix-B 20 mcg/mL) administered at months 0, 1, and 6 or an accelerated vaccination schedule on days 0, 7 to 14, and 21 to 28 between June 1988 and October 2012 were studied. Patients who were more likely to undergo LT within 6 months of evaluation received the accelerated vaccination schedule starting in August 2009.

First-in-human evaluation of a hexon chimeric adenovirus vector expressing HIV-1 Env (IPCAVD 002).

Background: We report the first-in-human safety and immunogenicity assessment of a prototype hexon chimeric adenovirus (Ad) serotype 5 (Ad5) vector containing the hexon hypervariable regions of Ad serotype 48 (Ad48) and expressing human immunodeficiency virus (HIV) type 1 EnvA.

Methods: Forty-eight Ad5 and Ad48 seronegative, HIV-uninfected subjects were enrolled in a randomized, double-blind, placebo-controlled, dose escalation phase 1 study. Four groups of 12 subjects received 10(9) to 10(11) viral particles (vp) of the Ad5HVR48.

Femoral artery percutaneous revascularization for patients with critical limb ischemia: outcomes compared to patients with claudication over 2.5 years.

Patients with critical limb ischemia have higher rates of death and amputation after revascularization compared to patients with intermittent claudication. However, the differences in patency after percutaneous revascularization of the superficial femoral artery are uncertain and impact the long-term risk of amputation and function in critical limb ischemia. We identified 171 limbs from 136 consecutive patients who had angioplasty and/or stenting for superficial femoral artery stenoses or occlusions from July 2003 through June 2007.

Percutaneous revascularization of long femoral artery lesions for claudication: patency over 2.5 years and impact of systematic surveillance.

Background: Angioplasty and stenting are preferred treatments for revascularizing femoral artery lesions up to 100 mm, but surgical bypass is recommended for longer lesions. We assessed long-term patency after percutaneous revascularization of long femoral artery lesions for claudication with intensive out-patient surveillance.

Methods: We followed a cohort of 111 consecutive patients receiving angioplasty or stenting in 142 limbs in two institutions.
