Patients with end-stage heart failure often present with concomitant end-stage renal or end-stage liver disease requiring transplantation. There are limited data regarding the risks, benefits and long-term outcomes of heart-kidney (HKT) and heart-liver transplantation (HLT), and guidelines are mainly limited to expert consensus statements.The incidence of HKT and HLT has steadily increased in recent years with favourable outcomes. Both single-centre and large database studies have shown benefits of HKT/HLT through improved survival, freedom from dialysis and lower rates of rejection and coronary allograft vasculopathy. Current guidelines are institution dependent and controversial due to the ethical considerations surrounding multiorgan transplantation (MOT).MOT is an effective and necessary option for patients with end-stage heart and kidney/liver failure. MOT is ethically permissible, and efforts should be made to consider eligible patients as early as possible to limit morbidity and mortality. Further research is needed regarding appropriate listing criteria and long-term outcomes.

Cardiopulmonary resuscitation (CPR) is a first-line therapy for sudden cardiac arrest, while extracorporeal membrane oxygenation (ECMO) has traditionally been used as a means of countering circulatory failure. However, new advances dictate that CPR and ECMO could be complementary for support after cardiac arrest. This review details the emerging science, technology, and clinical application that are enabling the new paradigm of these iconic circulatory support modalities in the setting of cardiac arrest.

BACKGROUND Electronic health records (EHRs) have become a standard in the health care setting. In an effort to improve health literacy, foster doctor-patient communication, and ease the transition from adolescent to adult care, our institution created a policy that allows patients aged between 13 and 17 years to have EHR portal access. A literature review revealed predictable differences in portal registration among different ethnicities and socioeconomic statuses. Consequently, a cross-sectional survey was developed to investigate barriers to EHR portal access in a sample of culturally diverse adolescents. OBJECTIVE The aim of this study was to assess for barriers to EHR portal access in a culturally diverse adolescent population. METHODS A 42-item anonymous survey was completed by 97 adolescents aged between 13 and 18 years, attending general pediatrics clinics. The results were analyzed using descriptive statistics and t tests. RESULTS The average participant age was 15.5 (SD 1.5) years with 60% (58/97) male and 40% (39/97) female. Participants were 44% (43/97) black, 41% (40/97) Hispanic, 9% (9/97) Caucasian, 3% (3/97) Asian, and 2% (2/97) others. There were statistically significant differences in perceptions of confidentiality in age (13 to 15 years vs 16 to 18 years; P=.001) and insurance status (government vs private; P=.012) but not in gender, ethnicity, or parental education level. Younger adolescents with governmental insurance were more confident in the level of confidentiality with their physician. A total of 94% of participants had heard of the term EHR, but only 55% were familiar with its function. Furthermore, 77% of patients primarily accessed the internet through phones, and 50% of participants knew that patients aged under 18 years could obtain care for mental health, substance abuse, sexual health, and pregnancy. CONCLUSIONS This research has identified gaps in EHR technology with regard to the pediatric patient population. The results of our survey show that adolescents may have misconceptions regarding the doctor-patient relationship, their ability to obtain care, and the modalities present in an EHR. As technology progresses, it is essential to have a deeper understanding of adolescents’ perceptions of confidentiality, technology, and available resources to design an EHR system that encourages patient education and communication while limiting barriers to care.

Background Left ventricular assist devices (LVAD) provide a lifesaving bridge to cardiac transplant. Utilization of these devices is increasing in the United States. When a patient undergoes cardiac transplant, the left ventricular device is surgically removed and the driveline is extracted or left tunneled in the subcutaneous tissue. Our group encountered a rare and previously unreported complication of this device: intraperitoneal infiltration of a retained driveline after cardiac transplant causing a small bowel obstruction. Case presentation A 62 year old male with a past medical history of non-ischemic cardiomyopathy induced heart failure, status post bridging left ventricular assist device and orthotopic heart transplant presented with abdominal distention, tenderness, and leukocytosis six days post-transplant. CT abdomen and pelvis revealed dilated loops of bowel, air-fluid levels and a transition point in the proximal small bowel. The patient was diagnosed with small bowel obstruction and taken for exploratory laparotomy. He was found to have a retained intraabdominal LVAD driveline strangulating a loop of small bowel in the left upper quadrant. The driveline was removed and the section of bowel released with return of perfusion. Conclusions We had encountered a rare complication of retained left ventricular assist device driveline after cardiac transplant: inadvertent penetration into the peritoneal cavity resulting in strangulation of small bowel. This complication, though uncommon, provides substantial risk to patients previously treated with left ventricular assist devices. Meticulous care must be taken to ensure proper device insertion and extraction, as well as consideration of this etiology when patients present with bowel obstruction after cardiac transplant.

Background Interventional radiology and cardiology procedures contribute significantly to the collective dose of radiation exposure from medical interventions. Recent and dedicated studies comparing directly these procedures in term of patient radiation exposure are lacking. Our aim was to compare radiation exposure among different interventional procedures performed under fluoroscopic guidance. Methods The RODEO study (NCT: 02972736) is an international observational retrospective multicenter study enrolling all patients undergoing diagnostic or interventional procedures performed by different interventional operators (i.e. radiologists, interventional cardiologists or electrophysiologists) in 6 centers, without exclusion criteria. The primary end-point of the study was the comparison of dose area product (DAP) among interventional cardiology, electrophysiology or interventional radiology procedures. Results A total of 17,711 procedures were included in the study: 13,522 interventional cardiology, 2352 electrophysiology and 1864 interventional radiology procedures. The highest DAP values were observed for interventional radiology procedures (74Gy∗cm 2 [Interquartile range 27–178Gy∗cm 2 ]), followed by interventional cardiology (40Gy∗cm 2 [22–78Gy∗cm 2 ]) and electrophysiology procedures (13Gy∗cm 2 [4–44Gy∗cm 2 ], p 2 [51–260Gy∗cm 2 ]) whereas the lowest DAP values in pacemaker insertion (11Gy∗cm 2 [4–28Gy∗cm 2 ]). Conclusion In this large multicenter study, the highest radiation exposure was observed in procedures performed by interventional radiologists. However, among specific procedures, structural or valvular cardiac procedures were associated with the highest radiation exposure.

Plasmacytoid Dendritic Cells (pDCs) represent a key immune cell population in the defense against viruses. pDCs detect viral pathogen associated molecular patterns (PAMPs) through pattern recognition receptors (PRR). PRR/PAMP interactions trigger signaling events that induce interferon (IFN) production to initiate local and systemic responses. pDCs produce Type I and Type III (IFNL) IFNs in response to HCV RNA. Extracellular HCV core protein (Core) is found in the circulation in chronic infection. This study defined how Core modulates PRR signaling in pDCs. Type I and III IFN expression and production following exposure to recombinant Core or β-galactosiade was assessed in human GEN2.2 cells, a pDC cell line. Core suppressed type I and III IFN production in response to TLR agonists and the HCV PAMP agonist of RIG-I. Core suppression of IFN induction was linked with decreased IRF-7 protein levels and increased non-phosphorylated STAT1 protein. Circulating Core protein interferes with PRR signaling by pDCs to suppress IFN production. Strategies to define and target Core effects on pDCs may serve to enhance IFN production and antiviral actions against HCV.
