  • Giant Spin Hall Effect in Cu-Tb Alloy Thin Films. [Journal Article]
    ACS Appl Mater Interfaces. 2020 Jul 01 [Online ahead of print]Xu Z, Wong GDH, … Lew WS
  • We report the giant spin-current generation in CuTb alloys arising from the spin Hall effect. The maximum spin Hall angle from our CuTb-based magnetic heterostructures was found to be -0.35±0.02 for Cu0.39Tb0.61. We find that the contribution of skew scattering is larger than side jump for lower Tb concentrations (<14.9%), while the converse is true for higher Tb concentrations. Additionally, we …
  • Serological and molecular prevalence of Hepatitis E Virus (HEV) among blood donors from Uruguay. [Journal Article]
    J Med Virol. 2020 Jun 27 [Online ahead of print]Bangueses F, Abin-Carriquiry JA, … Mirazo S
  • Hepatitis E virus (HEV) infection is considered a neglected disease of major concern in developed countries. Clinically, HEV occurs as an acute and self-limited disease, though chronic cases mostly associated to HEV-3 are now being commonly reported in immunocompromised individuals and solid organ transplant (SOT) recipients. Transmission of HEV through blood and derivates have been increasingly …
  • Effect of Mental Fatigue on Postural Sway in Healthy Older Adults and Stroke Populations. [Journal Article]

  • The aim of this study was to examine the effect of mental fatigue on postural sway under different sensory conditions in healthy older adults and in persons with chronic stroke (PwCS). Thirty healthy older adults (> 60 years old), randomly separated into experimental and control groups, as well as 15 PwCS participated in this study. Experimental groups were asked to stand on a force platform wear…
  • Persistent hypogammaglobulinemia in pediatric solid organ transplant recipients. [Journal Article]
    Clin Transplant. 2020 Jun 23 [Online ahead of print]Pellett Madan R, Penkert RR, … Hurwitz JL
  • CONCLUSIONS: Hypogammaglobulinemia was prevalent and persistent among pediatric SOT recipients and may be secondary to immunosuppressive medications, as well as loss of thymus tissue and CD45RA+CD4+ T cells in heart recipients. Limitations of our study include but are not limited to small sample size from a single center, lack of samples for all participants at every time point, and lack of peripheral blood mononuclear cell samples for the non-transplanted cohort.
  • T-cell responses following Natural Influenza Infection or Vaccination in Solid Organ Transplant Recipients. [Journal Article]
    Sci Rep. 2020 Jun 22; 10(1):10104.L'Huillier AG, Ferreira VH, … Kumar D
  • Little is known about cell-mediated immune responses to natural influenza infection in solid organ transplant (SOT) patients. The aim of our study was to evaluate the CD4+ and CD8+ responses to influenza A and B infection in a cohort of SOT patients. We collected peripheral blood mononuclear cells at influenza diagnosis and four weeks later from 31 SOT patients during the 2017-2018 influenza seas…
  • Universal molecular Clostridioides difficile screening and overtreatment in solid organ transplant recipients. [Journal Article]
    Transpl Infect Dis. 2020 Jun 22 [Online ahead of print]McCort MN, Oehler C, … Pisano J
  • CONCLUSIONS: Solid organ transplant recipients were more likely to have CD colonization detected by peri-rectal screening than the general inpatient population. SOT and non-SOT patients were treated with oral vancomycin at similar rates in response to the positive screen. Nearly half of the oral vancomycin use in SOT recipients was likely overtreatment, but this finding is limited by the low number of patients in this cohort.
  • Brachybacterium nesterenkovii isolated from a human blood culture-a first report. [Journal Article]
    New Microbes New Infect. 2020 Jul; 36:100699.Brummaier T, Hinfothong P, … Ling C
  • Brachybacterium is a genus of Gram-positive bacteria that rarely causes infections in humans. Here we report the case of an 8-month-old infant who presented with an acute febrile illness. During the diagnostic process, a blood culture was positive with Gram-positive cocci that were identified as Brachybacterium nesterenkovii by MALDI-TOF. As a result of the unclear clinical significance of this i…
  • Invasive Fungal Diseases in Kidney Transplant Recipients: Risk Factors for Mortality. [Journal Article]
    J Clin Med. 2020 Jun 11; 9(6)Seok H, Huh K, … Peck KR
  • CONCLUSIONS: A total of 50% of IFD cases occurred six months or later after transplantation. The IFD-related mortality rate was high in kidney transplant recipients despite the low incidence. DM and acute rejection were associated with high mortality, as well as IFD development. As old age, deceased donor transplantation, lymphocyte-depleting antibody usage, and concomitant bacterial infection are risk factors for IFD-related mortality, efforts for its early diagnosis and appropriate treatment are required.
  • Postural stability and dynamic balance in adult spinal deformity: prospective pilot study. [Journal Article]
    World Neurosurg. 2020 Jun 11 [Online ahead of print]Godzik J, Frames CW, … Turner JD
  • CONCLUSIONS: ASD patients demonstrated impaired postural stability, diminished sensory integration, and delayed response to external perturbations compared with normal control data. Postural stability and quality of life metrics correlated with self-reported falls. These findings suggest that ASD patients have abnormal postural stability and may be at elevated risk of falls.
  • Combining Ag and γ-Fe2O3 properties to produce effective antibacterial nanocomposites. [Journal Article]
    Colloids Surf B Biointerfaces. 2020 Jun 04; 194:111178.Luengo Y, Sot B, Salas G
  • The antibacterial activity of hybrid γ-Fe2O3/Ag nanocomposites against the bacterial pathogens E. coli (Gram-negative) and S. aureus (Gram-positive) has been studied. Silver is a well-known bactericidal agent and γ-Fe2O3 nanoparticles release heat when they are exposed to alternating magnetic fields. The combination of both properties to fight infections has not been previously explored. The nano…

  • The CD4+ T Cell Response to Human Cytomegalovirus in Healthy and Immunocompromised People. [Review]
    Front Cell Infect Microbiol. 2020; 10:202.Lim EY, Jackson SE, Wills MR
  • While CD8+ T cells specific for human cytomegalovirus (HCMV) have been extensively studied in both healthy HCMV seropositive carriers and patients undergoing immunosuppression, studies on the CD4+ T cell response to HCMV had lagged behind. However, over the last few years there has been a significant advance in our understanding of the importance and contribution that CMV-specific CD4+ T cells ma…
  • Acute kidney injury and chronic kidney disease after non-kidney solid organ transplantation. [Journal Article]
    Pediatr Transplant. 2020 Jun 04 [Online ahead of print]Menon S, Pollack AH, … Smith J
  • CONCLUSIONS: pAKI and CKD are common after NKSOT. Incidence of CKD is higher in those with pAKI. AKI episodes are associated with a drop in eGFR during follow-up. Identifying patients who have had AKI is an important first step in identifying those at risk of repeated AKI episodes. These patients would benefit from closer monitoring for CKD, lower nephrotoxic drug use, and follow-up with nephrology.
