Contemporary Management Strategies in VAD Infection

AbstractPurpose of ReviewThe use of durable ventricular assist devices (VAD) to manage end-stage heart failure is increasing, but infection remains a leading cause of morbidity and mortality among patients with VAD. In this review, we synthesize recent data pertaining to the epidemiology, diagnosis, management, and prevention of VAD infections, discuss transplant considerations in patients with VAD infections, and highlight remaining knowledge gaps. We also present a conceptual framework for treating clinicians to approach these infections that draws on the same principles that guide the treatment of analogous infections that occur in patients without VAD.Recent FindingsDespite advances in device design, surgical techniques, and preventative interventions, more than a third of VAD recipients still experience infection as an adverse outcome. Positron emission tomography has emerged as a promising modality for identifying and characterizing VAD infections. High-quality data to support many of the routine therapeutic strategies currently used for VAD infections —including suppressive antibiotic therapy, surgical debridement/device exchange, and novel antimicrobials for emerging multidrug-resistant organisms—remain limited. Although pre-transplant VAD infection may impact some early transplant outcomes, transplantation remains a viable option for patien ts with most types of VAD infection.SummaryStandardized definitions of VAD infection applied to large registry datas...

The original version of this article, published on 10 February 2019, unfortunately contained a mistake. The axes of the graphs in Fig.  3 are incorrect. The correct figure is given below. Therefore, the last two sentences in “Results,” section “Noise,” should read: “The peak frequency of the HR and SHR was0.21 lp/mm. For the NR mode and the MDCT, the peak frequencies were0.17 lp/mm and0.21 lp/mm, respectively. ”

AbstractObjectivesResults after trans-arterial radioembolisation (TARE) for intrahepatic cholangiocarcinoma (iCC) depend on the architecture of the tumour. This latter can be quantified through computed tomography (CT) texture analysis. The aims of the present study were to analyse relationships between CT textural features prior to TARE and objective response (OR), progression-free survival (PFS), and overall survival (OS).MethodsTexture analysis was retrospectively applied to 55 pre-TARE CT scans of iCCs, focusing attention on the histogram-based features and the grey-level co-occurrence matrix (GLCM). Texture features w...

NEW BRUNSWICK, NJ, May 27, 2020 — The Janssen Pharmaceutical Companies of Johnson &Johnson today announced that the U.S. Food and Drug Administration (FDA) has granted approval for a new pediatric formulation of SIRTURO® (bedaquiline). SIRTURO® is now indicated for use as part of combination therapy in the treatment of adult and pediatric patients (5 years and older and weighing at least 15 kg) with pulmonary multidrug-resistant tuberculosis (MDR‑TB). In the U.S., the medicine should be reserved for use when an effective treatment regimen cannot otherwise be provided. This indication received accelera...

CONCLUSIONS: Pectoralis muscle flaps are the workhorse for complex sternal wound coverage, but complications following flap reconstruction for DSWIs remain high. In particular, end-stage renal disease, VRAM reconstruction and MDR infection may predict a complicated post-operative course in these patients. PMID: 31982440 [PubMed - as supplied by publisher]

ConclusionsIn HF patients, the autonomic vasomotor response to postural stress is abnormal, more pronounced with increasing disease severity, and frequently associated with overt postural hypotension. These phenomena appear related to the cardiac condition rather than treatment.

Abstract Left ventricular assist devices improve survival prospects in patients with end-stage heart failure; however, infection complicates up to 59% of implantation cases. How many of these infections are caused by multidrug-resistant organisms is unknown. We sought to identify the incidence, risk factors, and outcomes of multidrug-resistant organism infection in patients who have left ventricular assist devices. We retrospectively evaluated the incidence of multidrug-resistant organisms and the independent risk factors associated with them in 57 patients who had permanent left ventricular assist devices implant...

Conclusions: Among patients with Pa-NP the presence of infection with a MDR strain is associated with increased in-hospital mortality. Identification of patients at risk of MDR Pa-NP could facilitate appropriate empiric antibiotic decisions that in turn could lead to improved hospital survival.
