28, SE = 0.04, p < .001). Childhood maltreatment also had a significant indirect effect on PTSD via cognitive reappraisal (β = 0.01, CI 95 % ), but not through thought suppression, although (β = 0.01, CI 95 % ) thought suppression was significantly positively associated with PTSD symptoms (β = 0.21, SE = 0.04, p < .001).
The present study sheds light on the effect of childhood maltreatment and two commonly used emotion regulation strategies on PTSD symptoms.

It is becoming increasingly clear that the bacterial enteric community highly influences the phenotype. Eukaryotic viruses represent a sparsely investigated member of the enteric microbiome that might also affect the phenotype. We here investigated the presence of enteric eukaryotic DNA viruses (EDVs) in specific pathogen-free (SPF) C57BL/6N mice purchased from three vendors upon arrival and after being fed a low-fat diet (LFD) or high-fat diet (HFD). We detected genetic fragments of EDVs belonging to the viral families of Herpes-, Mimi-, Baculo- and Phycodnaviridae represented by two genera; Chlorovirus and Prasinovirus. The EDVs were detected in the mice upon arrival and persisted for 13 weeks. However, these signals of EDVs were only detected at notable levels in mice fed LFD from 2 out of 3 vendors, which suggested that the enteric composition of these EDVs were affected by both vendor (p less then 0.003) and different dietary regimes (p less then 0.013). This highlights the need of additional studies assessing the potential function of these EDVs that may influence the mouse phenotype and the reproducibility of animal studies using this C57BL/6N substrain.
Neuroendocrine tumor (NET) metastasis localized to the liver is an accepted indication for liver transplantation as such tumors have a low biological aggressiveness in terms of malignancy and are slow growing.
The long-term results are comparable with and in some cases even better than those of transplantations performed for primary liver cancer. However, compared with nonmalignant conditions, neuroendocrine liver metastasis (NELM) may result in an inferior outcome of transplantation. In the face of the scarcity of donated organs and recent improved results of non-surgical treatment for NELM, controversy over patient selection and timing for liver transplantation continues.
In this review, we provide an overview of the diagnostic work-up and selection criteria of patients with NELM being considered for liver transplantation. Thereafter, we provide a critical analysis of the reported outcomes of OLT.

The uptake of low- and high-density lipoproteins (LDL and HDL) through the LDL receptor (LDLR) and the scavenger receptor class B type I (SR-BI) mediates maternal to fetal cholesterol transfer in syncytiotrophoblast (STB) cells. STB cells deliver cholesterol via cholesterol efflux through the ATP-binding cassette transporters A1 (ABCA1, to ApoA-I), G1 (ABCG1, to HDL), and SR-BI (to HDL). In the human placenta, these proteins are localized in the apical (LDLR, SR-BI, ABCA1) and basal (SR-BI, ABCA1, ABCG1) membrane of STB cells. However, whether these proteins in polarized primary culture models of STB show a similar localization to those in the human placenta is currently unknown.
Primary human trophoblasts (PHT) were isolated from normal placentas and cultured in Transwells® with Matrigel to obtain a polarized STB monolayer, proteins were determined by immunofluorescence and cholesterol efflux determined to different acceptors.
At day 5, LDLR and ABCA1 localized mainly in the apical membrane, ABCG1 in the basal membrane, and SR-BI in both. Cholesterol efflux towards the apical compartment was higher to adult and neonatal HDL compared to ApoA-I. When acceptors were added in the basal compartment, cholesterol was retained in the Matrigel.
Polarized STB monolayers express LDLR, SR-BI, ABCA1 and ABCG1, and their apical/basal localization resembles the one described in human placental tissue. This study confirms the high physiological value and suitability of this model for use in functional studies. Our findings also suggest that ABCA1 and SR-BI participate in cholesterol efflux to the maternal side of the cells.

While it has disproportionately caused severe illness in the elderly and older adult population, many children have also been infected with the virus and some have become critically ill. It is important to recognize COVID-19 may present differently in children; specifically, those under twelve months of age. We report a case of COVID-19 infection in an infant characterized by a bulging anterior fontanelle without any additional symptoms.
Human herpesvirus 6 (HHV-6) can reactivate with immunosuppression and cause central nervous system (CNS) dysfunction. Much of the literature describes cases after hematopoietic stem cell transplantation (HSCT), ranging from encephalitis to a post-transplant acute limbic encephalitis syndrome (PALE). Outside of HSCT, studies of HHV-6 encephalitis are limited to case reports.
This study was designed to review HHV-6 CNS infection, and evaluate all patients admitted to MD Anderson Cancer Center between March 2016 and December 2018 with detectable HHV-6 DNA in the cerebrospinal fluid (CSF).
Patients with HHV-6 DNA detected in the CSF using the Viracor or Biofire® Meningitis Encephalitis Panel platforms and no other identified etiology were identified and demographic features, known risk factors, imaging findings, CSF analysis, treatments and patient outcomes were extracted from medical records.
725 patients underwent HHV-6 testing during the study timeframe, with 19 cases (2.6 %) of HHV-6 mediated CNS disease identified.
