Published: May 2020

AbstractIn three studies we examined the associations between resource sharing (RS) and attachment, and the enhancement of RS using attachment security primes. In Study 1, we showed that attachment avoidance was negatively associated with RS. We also identified differences and similarities between RS and pro‐sociality. In Studies 2 and 3, we showed that research participants were more likely to share their monetary resources after they were primed with attachment security. Study 3 further revealed that security priming affected mainly people low on state attachment anxiety. Our findings extend previous work on pro‐sociality into the specific realm of RS, provide behavioral evidence, and tie attachment and close relationships in with game theory and research on economic decision making.

AbstractPPCA has historically been considered detrimental to donor quality in LT, but transplantation of grafts from this group of donors is now routine. Our study aims to evaluate the outcomes associated with use of donors with a history of PPCA in the pediatric population. This study is a single‐center retrospective analysis of all pediatric LTs performed over an 18‐year period. Donors and recipients were stratified by the presence and length of donor PPCA time. Preprocurement donor and post‐transplant recipient laboratory values were collected to assess the degree of ischemic liver injury associated with each donor group. Cox regression analysis was used to compare survival. The records for 130 deceased pediatric LT donors and corresponding recipients were reviewed. There were 73 (56%) non‐PPCA donors and 57 (44%) PPCA donors. Donors that experienced a PPCA event demonstrated a higher median, pretransplant peak alanine aminotransferase (ALT) level (P < .001). When comparing post‐transplant recipient median ALT levels, donors with any PPCA had lower median peak ALT (P = .15) and day 3 ALT (P = .43) levels than the non‐PPCA group. Rates of early graft loss did not differ. The PPCA group with >40 minutes of ischemia had markedly lower survival at 10 years, but this finding did not reach statistical significance. Liver grafts from donors with or without PPCA demonstrated no statistically significant differences in function or survival. A history of donor PPCA alone should not be used as an exclusionary criterion in pediatric liver transplantation.

AbstractPost‐transplant lymphoproliferative disorders (PTLD) are the main malignancy seen after pediatric heart transplant and are a significant cause of morbidity and mortality. Prior to the development of detailed guidelines, we sought to identify trends in screening, diagnosis, and treatment of pediatric PTLD. All Pediatric Heart Transplant Society (PHTS) institutions were surveyed. No identifiable patient information was shared. From 56 PHTS centers, 22 responses were received (39.3%). 100% agree PTLD cannot be diagnosed solely based on elevated Epstein‐Barr virus (EBV) load. All respondents routinely screen for EBV by blood PCR, but frequency of screening varies. There was intermediate consensus regarding the use of computed tomography (CT) and/or positron emission tomography (PET) in surveillance management for PTLD. Most centers require a diagnostic biopsy before initiating new treatment for PTLD (14 of 18, 77.8%), but many reduce immune suppression based on elevated EBV without pathologic PTLD (16 of 22, 72.7%). Beyond immune modulation, rituximab is most commonly used (9 of 13, 69.2%). Consultation with oncology is common (17 of 17, 100%), but timing varies widely. Our survey highlights significant elements of agreement and significant practice variation among PHTS institutions regarding pediatric PTLD. Reduction of immune suppression prior to pathologic diagnosis of PTLD is a common management strategy. When this fails, rituximab is used, but is most often reserved until after confirmation of the diagnosis. Oncology subspecialists are commonly involved in these cases. Our findings highlight the need to develop improved guidelines for evaluation and treatment of pediatric PTLD.

AbstractBK virus encephalitis after HSCT is uncommon. Several reports of native kidney BKVN in patients with HSCT, hematologic malignancies, human immunodeficiency virus infection, and non‐renal solid organ transplantation have been described. However, an uncommon combination of BK encephalitis and ESRD of native kidneys secondary to BK virus in a child with HSCT has not been described. We report a 10‐year‐old boy who presented with a gradually rising serum creatinine during treatment for severe autoimmune hemolytic anemia, which he developed 9 months after receiving an allogeneic HSCT for aplastic anemia. There was no proteinuria or hematuria present. Serum BK virus load was 5 × 106 copies/mL. A renal biopsy showed evidence of BKVN. He developed fever, seizures, and confusion, and the (CSF) showed significant presence of the BK virus (1 × 106 copies/mL) along with biochemical evidence of viral encephalitis. Cerebrospinal fluid cultures were negative. Despite significant clinical symptoms and presence of BK virus in CSF, the magnetic resonance brain imaging findings were minimal. With reduction of immunosuppression, there was resolution of BK encephalitis but BKVN remained resistant to multiple anti‐BK virus agents, including leflunomide and cidofovir. He eventually became dialysis‐dependent and, 6 years later, received a renal transplant from his mother. This case illustrates that BK virus in severely immunocompromised HSCT recipient may lead to BK encephalitis and BKVN of native kidneys, even without hemorrhagic cystitis, leading to ESRD. Knowledge of such is important for appropriate timely evaluation and management.

AbstractError‐monitoring processes may be affected by transdiagnostic dimensions of psychopathology symptoms including trait anxiety, worry, and severity of depressive symptoms. We tested the relationship between continuous measures of anxiety and depressive symptomology and neural correlates of error‐monitoring as measured by time‐frequency domain delta and theta oscillatory power and time‐domain error‐related negativity (ERN) amplitude extracted from the electroencephalogram (EEG). Secondary analyses tested for diagnostic group differences in error‐related neural responses in individuals with generalized anxiety disorder (GAD), major depressive disorder (MDD), and comorbid psychiatric disorders. About 178 participants (104 female, M[SD]age = 21.7[4.6]) with a wide range of psychopathology symptoms completed a modified version of the Eriksen flanker task and symptom questionnaires. Residualized difference values between correct and error trials for delta/theta power and error/correct ERN amplitude were used as dependent variables. Linear regression analyses adjusted for age, sex, and task accuracy showed nonsignificant associations of symptom dimension measures with error‐related residualized delta/theta power or residualized ERN amplitude. Subset analyses on those with confirmed psychopathology diagnoses also did not predict residualized error‐related delta/theta power nor residualized ERN amplitude (nGAD = 14, nMDD = 28, nComorbid = 19, nControl = 85). Taken in the context of the previous literature, results suggest a heterogeneous relationship between depressive and anxiety symptom dimensions and neurophysiological indices of error‐monitoring.

Published: May 2020

AbstractOur aim is to describe a family with a nonsyndromic form of hereditary gingival fibromatosis (HGF) and discuss genetic characteristics of this rare disease by reviewing reported cases.A mother and three descendants were diagnosed with HGF. There was marked variable expressivity: from severe generalized gingival overgrowth in a 16‐year‐old boy (the proband) to minimal manifestations in the mother. The proband was submitted to gingivectomy and gingivoplasty. In younger siblings, the disease remained stable for 5 years, suggesting that clinical surveillance is a good option. The diagnosis was supported by histopathological examination.Analysis of this family and literature‐reported cases supports that HGF most frequently shows an autosomal dominant inheritance with high penetrance and variable expressivity. Neomutations and gonadal mosaicism do not seem to be a rare event. Although five loci have been mapped by linkage analysis, only two genes, SOS1 and REST, were identified in four families.

AbstractCoronavirus disease 2019 (COVID‐19) has been a pandemic worldwide. The data about COVID‐19 in renal transplant recipient are deficiency. Herein, we report two COVID‐19 cases in renal transplant recipients. Both cases were discharged following a treatment regimen including discontinued immunosuppressant and low‐dose methylprednisolone‐based therapy. There were no signs of rejection during the treatment. These successfully treated cases can provide helpful information about the management of COVID‐19 in renal transplant recipients.

SummaryThe architecture of endosperm cell walls in Hordeum vulgare (barley) differs remarkably from that of other grass species and is affected by germination or malting. Here, the cell wall microstructure is investigated using (bio)chemical analyses, cryogenic scanning electron microscopy (cryo‐SEM) and confocal laser scanning microscopy (CLSM) as the main techniques. The relative proportions of β‐glucan, arabinoxylan and pectin in cell walls were 61, 34 and 5%, respectively. The average thickness of a single endosperm cell wall was 0.30 µm, as estimated by the cryo‐SEM analysis of barley seeds, which was reduced to 0.16 µm after malting. After fluorescent staining, 3D confocal multiphoton microscopy (multiphoton CLSM) imaging revealed the complex cell wall architecture. The endosperm cell wall is composed of a structure in which arabinoxylan and pectin are colocalized on the outside, with β‐glucan depositions on the inside. During germination, arabinoxylan and β‐glucan are hydrolysed, but unlike β‐glucan, arabinoxylan remains present in defined cell walls in malt. Integrating the results, an enhanced model for the endosperm cell walls in barley is proposed.

AbstractThe green fluorescent protein (GFP) from Aequorea victoria has been engineered extensively in the past to generate variants suitable for protein tagging. Early efforts produced the enhanced variant EGFP and its monomeric derivative mEGFP, which have useful photophysical properties, as well as superfolder GFP, which folds efficiently under adverse conditions. We previously generated msGFP, a monomeric superfolder derivative of EGFP. Unfortunately, compared to EGFP, msGFP and other superfolder GFP variants show faster photobleaching. We now describe msGFP2, which retains monomeric superfolder properties while being as photostable as EGFP. msGFP2 contains modified N‐ and C‐terminal peptides that are expected to reduce nonspecific interactions. Compared to EGFP and mEGFP, msGFP2 is less prone to disturbing the functions of certain partner proteins. For general‐purpose protein tagging, msGFP2 may be the best available derivative of A. victoria GFP.

BACKGROUNDPlatelet transfusion is associated with logistical problems with the national storage guidelines of platelets. This results in decreased function in vivo as a result of the platelet storage lesion, and complications such as allergic or hemolytic reactions and thrombosis. We evaluated a new, freshly prepared platelet modified lysate (PML) product designed to be more procoagulant than fresh and stored platelets.METHODSFresh platelets were concentrated, sonicated, and centrifuged to produce PML. Samples of both washed and unwashed PML were evaluated for particle size, concentration, and activity, and then tested for clot kinetics and thrombin generation. PML samples were also stored at various temperatures for durations up to 6 months and evaluated for clot kinetics and thrombin generation throughout.RESULTSPML showed significantly higher concentration of platelet microparticles, increased procoagulant properties, and increased thrombin generation as compared to fresh and stored platelets. In addition, PML maintained its clot kinetics over a 6‐month storage period with variable storage conditions.CONCLUSIONSThe newly proposed PML product is more procoagulant, stable, and has additional potential applications than currently available platelet products. Further studies will be performed to assess its functions in vivo and to assess thrombotic potential.

AbstractObjectiveTo provide an updated overview of feline orbital neoplasia, to compare diagnostic utility of cytology and histopathology, and to evaluate minimally invasive sampling modalities.ProceduresA medical records search was performed to identify cats with orbital neoplasia. Data were collected regarding signalment, diagnosis, vision status, imaging modalities, and sample collection methods. A reference population with orbital neoplasia was also identified via literature search for comparison with regard to final diagnosis.ResultsEighty‐one cats met selection criteria and 140 cases were identified in the literature. In the study and reference populations, respectively, diagnoses were grouped as follows: round cell tumors 47% and 24%, epithelial tumors 38% and 40%, mesenchymal tumors 14% and 34%, and neurologic origin tumors 1% and 2%. The most common diagnoses in both groups were lymphoma and squamous cell carcinoma (SCC). Feline restrictive orbital myofibroblastic sarcoma (FROMS) was common in the reference population but not diagnosed in the study population. Cytology results were available for 41 cats; histopathology results were available for 65 cats. Both cytology and histopathology results were available for 25 cats, in 44% of which cytologic results were overturned. No significant complications were associated with any sampling method. Lack of cats with multiple samples available for histopathology limited comparison between tissue sampling methods.ConclusionsOrbital neoplasia is common in cats, with round cell and epithelial tumors diagnosed most commonly in the study population. Histopathology is superior to cytology in providing a definitive diagnosis. Minimally invasive tissue biopsy techniques appear to be safe and effective.

AbstractObjectiveTo describe perioperative characteristics and outcomes of dogs surgically treated for intestinal intussusception.Study designMulti‐institutional, retrospective study.AnimalsOne hundred fifty‐three client‐owned dogs with intestinal intussusception.MethodsDogs were included when they had undergone surgical treatment of a confirmed intestinal intussusception. Medical records were reviewed for demographics and clinical data, including surgical complications (graded 1‐4). Follow‐up was obtained via telephone interview with owners and referring veterinarians.ResultsDogs had a median age of 10 months (range, 2‐156), and the most common location for intussusception was ileocolic (66/153 [43%]). Most cases had no identifiable cause (104/155 [67%]). Intestinal resection and anastomosis (IRA) was performed in 129 of 153 (84%) dogs; enteroplication was performed in 28 of 153 (18%) dogs, including 13 with and 15 without IRA. Intraoperative complications occurred in 10 of 153 (7%) dogs, all involving intestinal damage during attempted manual reduction. The median duration of follow‐up after discharge was 334 days (interquartile range, 15‐990; range, 1‐3302). Postoperative complications occurred in 53 of 153 (35%) dogs, including 22 of 153 (14%) with severe (grade 3 or 4) events. Diarrhea, regurgitation, and septic peritonitis were the most common postoperative complications; intussusception recurred in four of 153 (3%) dogs, all within 72 hours postoperatively. Fourteen‐day postoperative mortality rate was 6%.ConclusionSurgical treatment of intestinal intussusception was curative in most dogs, even when an underlying cause was not identified. Surgical complications were common, including a 14% risk of life‐threatening short‐term complications.Clinical significanceSurgical treatment of intestinal intussusception offers an excellent prognosis, but the potential life‐threatening complications should be considered.
An experimental study on reactive filter bed for aluminium removal from water
Authors: Chowdhury Saidur Rahman , Yanful Ernest K. 
Published: May 2020

AbstractIn this study, batch and column experiments were conducted to adsorb Aluminium (Al3+) from aqueous solution. The study examined the possibility of using proposed reactive filter bed media (packed with hematite or hematite sand mixture) for contaminated water treatment. Batch experiments were carried out at pH 7 ± 0.5 and initial Al3+ concentration of 1.5 mg/L. Adsorption equilibrium was achieved in more than 2 hours for hematite and 1 hour for hematite coated sand while conducting batch experiment and the maximum adsorption qm was found to be 3.38 mg/g for hematite mixture sand. From column experiment, the maximum Al adsorption capacity from four different columns was calculated to be approximately 2.2 mg/g and it was found in columns 1 and 3 packed with hematite sand mixture particles. The results indicated that both electrostatic attraction and chemical sorption could be the mechanism for Al3+ removal by hematite sand mixture particles from aqueous solution. Redox values (250 to 300 mV) inside column 3 suggested oxidizing condition during column operation. The continuous changes in redox potential (Eh) and pH indicated the occurrence of redox reactions between Al3+ and reactive media under the prevailing experimental conditions.
Relative water quality index (ReWQI) – a new method for aggregate water quality assessment
Authors: Pham Ho Ngoc 
Published: May 2020

AbstractWater quality index (WQI) is used for aggregate assessment of water pollution level. The method is used in the United States of America (USA) and some other countries including Vietnam, but it has several limitations: the weight of a parameter is subjectively defined by the experts' criteria; the hierarchical rating scale is self‐regulated and fixed; the individual index of WQI is calculated based on the segmented linear function, which are not convenient to apply in reality when expanding to an arbitrary number of selected survey parameters. In addition, in some cases, WQI results in ambiguity and eclipse (collectively called ‘Virtual effect’). To overcome these disadvantages, the author proposes Relative Water Quality Index (ReWQI). ReWQI's calculation is simple and it does not encounter ‘Virtual effect’. Results of ReWQI have been compared with results of the traditional method used by Department of Natural Resources and Environment of Hai Duong in 2016–2018.
