Abstract

Abstract Human genetic studies have revealed rare missense and protein-truncating variants in GRIN2A, encoding for the GluN2A subunit of the NMDA receptors, that confer significant risk for schizophrenia (SCZ). Mutations in GRIN2A are also associated with epilepsy and developmental delay/intellectual disability (DD/ID). However, it remains enigmatic how alterations to the same protein can result in diverse clinical phenotypes. Here, we performed functional characterization of human GluN1/GluN2A heteromeric NMDA receptors that contain SCZ-linked GluN2A variants, and compared them to NMDA receptors with GluN2A variants associated with epilepsy or DD/ID. Our findings demonstrate that SCZ-associated GRIN2A variants were predominantly loss-of-function (LoF), whereas epilepsy and DD/ID-associated variants resulted in both gain- and loss-of-function phenotypes. We additionally show that M653I and S809R, LoF GRIN2A variants associated with DD/ID, exert a dominant-negative effect when co-expressed with a wild-type GluN2A, whereas E58Ter and Y698C, SCZ-linked LoF variants, and A727T, an epilepsy-linked LoF variant, do not. These data offer a potential mechanism by which SCZ/epilepsy and DD/ID-linked variants can cause different effects on receptor function and therefore result in divergent pathological outcomes.

Abstract

IntroductionThere is a lack of comprehensive and uniform data on head and neck paragangliomas (HNPGLs), and research is challenging due to its rarity and the involvement of multiple medical specialties. To improve current research data collection, we initiated the Head and Neck Paraganglioma Registry (HNPGL Registry). The aim of the HNPGL Registry is to a) collect extensive data on all HNPGL patients through a predefined protocol, b) give insight in the long term outcomes using patient reported outcome measures (PROMs), c) create uniformity in the diagnostic and clinical management of these conditions, and thereby d) help provide content for future (randomized) research.Methods and analysisThe HNPGL Registry is designed as a prospective longitudinal observational registry for data collection on HNPGL patients and carriers of (likely) pathogenic variants causative of HNPGLs. All patients, regardless of the received treatment modality, can be included in the registry after informed consent is obtained. All relevant data regarding the initial presentation, diagnostics, treatment, and follow-up will be collected prospectively in an electronic case report form. In addition a survey containing the EuroQol 5D-5L (EQ-5D-5L), European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), Modified Fatigue Impact Scale (MFIS), Short QUestionnaire to Assess Health-enhancing physical activity (SQUASH), Cancer Worry Scale (CWS) and Hospital Anxiety and Depression Scale (HADS) will be sent periodically. The registry protocol was approved by the Medical Ethical Review Board of the University Medical Center Utrecht.ConclusionThe HNPGL Registry data will be used to further establish the optimal management for HNPGL patients and lay the foundation for guideline recommendations and the outline of future research.

Abstract

BackgroundAcute rejection (AR) after kidney transplantation is an important allograft complication. To reduce the risk of post-transplant AR, determination of kidney transplant donor-recipient mismatching focuses on blood type and human leukocyte antigens (HLA), while it remains unclear whether non-HLA genetic mismatching is related to post-transplant complications.MethodsWe carried out a genome-wide scan (HLA and non-HLA regions) on AR with a large kidney transplant cohort of 784 living donor-recipient pairs of European ancestry. An AR polygenic risk score (PRS) was constructed with the non-HLA single nucleotide polymorphisms (SNPs) filtered by independence (r2 < 0.2) and P-value (< 1×10-3) criteria. The PRS was validated in an independent cohort of 352 living donor-recipient pairs.ResultsBy the genome-wide scan, we identified one significant SNP rs6749137 with HR = 2.49 and P-value = 2.15×10-8. 1,307 non-HLA PRS SNPs passed the clumping plus thresholding and the PRS exhibited significant association with the AR in the validation cohort (HR = 1.54, 95% CI = (1.07, 2.22), p = 0.019). Further pathway analysis attributed the PRS genes into 13 categories, and the over-representation test identified 42 significant biological processes, the most significant of which is the cell morphogenesis (GO:0000902), with 4.08 fold of the percentage from homo species reference and FDR-adjusted P-value = 8.6×10-4.ConclusionsOur results show the importance of donor-recipient mismatching in non-HLA regions. Additional work will be needed to understand the role of SNPs included in the PRS and to further improve donor-recipient genetic matching algorithms. Trial registry: Deterioration of Kidney Allograft Function Genomics (NCT00270712) and Genomics of Kidney Transplantation (NCT01714440) are registered on ClinicalTrials.gov.

Abstract

Abstract The oceanic South Atlantic Convergence Zone (SACZ) has played a major role during South America’s 2021/2022 summer extreme rainy season, being responsible for more than 90% of the precipitation in some regions of Southeast Brazil and in some regions of the Southwestern Atlantic Ocean (SWA). The summer of 2021/2022 was unique and rare and considered an abnormally humid season as verified by official Brazilian Institutes. First, the unusual number of cases of SACZ episodes (seven), was the highest recorded in the last decade. Second, all the cases that occurred were oceanic SACZ that assumed characteristics of an Atmospheric River and produced an excessively anomalous amount of precipitation during this period. Excess precipitation along with the regions located in mountainous and very uneven relief, which by orographic effects favors high precipitation volumes, were responsible for amplifying the observed impacts, such as landslides and floods that caused several losses to society. We also showed the main effects of coupling and interaction between the waters of the surface layer of the SWA and the atmosphere. Our learning from this study ends with the unprecedented results of how the marine atmospheric boundary layer (MABL) is locally modulated by the sea surface temperature (SST) that lies just below it. Until the present moment, we emphasize that this important mechanism has not been widely highlighted in the literature, showing that even though the ocean is colder than before oceanic SACZ is established, it is still warmer than the overlying air, thus, the ocean continues to be an active source of heat and moisture for the atmosphere and enhances the MABL instability process.

Abstract

An in silico study of Aspergillus flavus genome stability uncovered significant variations in both coding and non-coding regions. The non-coding insertions uniformly consisted of AT-rich sequences that are evolutionarily maintained, albeit distributed at widely different sites in an array of A. flavus strains. A survey of ≥ 2kb AT-rich elements (AT ≥ 70%; ATEs) in non-centromeric regions uncovered two major categories of ATEs. The first category is composed of homologous insertions at ectopic, non-allelic sites that contain homology to transposable elements (TEs; Classes B, C, D, and E). Strains differed significantly in frequency, position, and TE type, but displayed a common enrichment in subtelomeric regions. The TEs were heavily mutated, with patterns consistent with the ancestral activity of repeat-induced point mutations (RIP). The second category consists of a conserved set of novel subtelomeric ATE repeats (Classes A, G, G, H, I and J) which lack discernible TEs and, unlike TEs, display a constant polarity relative to the telomere. Members of one of these classes are derivatives of a progenitor ATE that is predicted to have undergone extensive homologous recombination during evolution. A third category of ATEs consists of ~100 kb regions at each centromere. Centromeric ATEs and TE clusters within these centromeres display a high level of sequence identity between strains. These studies suggest that transposition and RIP are forces in the evolution of subtelomeric and centromeric structure and function.

Abstract

Muscle weakness and wasting are defining features of cancer-induced cachexia. Mitochondrial stress occurs before atrophy in certain muscles, but the possibility of heterogeneous responses between muscles and across time remains unclear. Using mice inoculated with Colon-26 cancer, we demonstrate that specific force production was reduced in quadriceps and diaphragm at 2 weeks in the absence of atrophy. At this time, pyruvate-supported mitochondrial respiration was lower in quadriceps while mitochondrial H2O2 emission was elevated in diaphragm. By 4 weeks, atrophy occurred in both muscles, but specific force production increased to control levels in quadriceps such that reductions in absolute force were due entirely to atrophy. Specific force production remained reduced in diaphragm. Mitochondrial respiration increased and H2O2 emission was unchanged in both muscles versus control while mitochondrial creatine sensitivity was reduced in quadriceps. These findings indicate muscle weakness precedes atrophy and is linked to heterogeneous mitochondrial alterations that could involve adaptive responses to metabolic stress. Eventual muscle-specific restorations in specific force and bioenergetics highlight how the effects of cancer on one muscle do not predict the response in another muscle. Exploring heterogeneous responses of muscle to cancer may reveal new mechanisms underlying distinct sensitivities, or resistance, to cancer cachexia.

Abstract

Objectives: Both, Human Immunodeficiency Virus (HIV) infection and malnutrition are major challenges in pregnancy and postpartum in low-resource settings and the respective cytokine levels remain poorly described. The main objectives of this study were to find immune markers that are associated with HIV infection and malnutrition in pregnant women and to determine how these would change at 14 weeks postpartum. Method: Pregnant women of at least 20 weeks gestational age were enrolled into this longitudinal observational single centre pilot study at 4 primary health clinics in high-density areas around Harare, Zimbabwe. Socio-demographic and clinical data including plasma samples were collected in pregnancy and 14 weeks postpartum (PP). Mid-upper-arm circumference (MUAC) ≤23 cm was used as an indicator for malnourishment. Fifty-six cytokines and chemokines were assayed in plasma using the Mesoscale multiplex assay. We determined cytokine/chemokine levels including markers for vascular injury in HIV-infection and malnutrition. Associations remaining significant after multiple test correction were confirmed in multivariable analyses after controlling for confounders. Results: Ninety-seven pregnant women were recruited for this study and from these, 44 were randomly selected for cytokine assaying of which 20 HIV infected, 15 malnourished, and 9 well-nourished HIV uninfected participants. HIV infection was associated with significantly higher interleukin (IL)-4 ( q < 0.05) and IL-10 ( q < 0.001) in pregnancy. Longitudinally, IL-4 ( q < 0.01) and IL-10 ( q < 0.001) significantly increased in HIV uninfected women whilst in the HIV-infected both were non-significantly decreased. IL-8 (q < 0.05) levels significantly increased in HIV-infected women from pregnancy to 14 weeks PP. Vascular Cell Adhesion Molecule 1 (VCAM-1) ( q < 0.05) and interleukin-1 receptor antagonist (IL-1RA) ( q < 0.05) were significantly lower in malnourished women in pregnancy and 14 weeks PP, respectively. Conclusions: IL-4, IL-8, IL-10, and VCAM-1 are potential biomarkers for monitoring immune functioning in HIV-infected pregnant women and malnutrition. However, studies with larger sample size are warranted to confirm these findings.

Abstract

Introduction Nowadays, two predominant methods for detecting sentinel lymph nodes (SLNs) in cervical cancer are in use. The most conventional method is a combination of a radiotracer, technetium-99m (99mTc) and blue dye. More recently, another method for SLN mapping using indocyanine green (ICG) is becoming widely accepted. ICG is a fluorescent dye, visualised intraoperatively with near-infrared (NIR) fluorescence imaging, providing real-time visual navigation. The presumed advantages of ICG over 99mTc, that is, being cheaper, non-radioactive and logistically more attractive, are only valuable if its detection rate proves to be at least non-inferior. Before omitting the well-functioning and evidence-based combined approach of 99mTc and blue dye, we aim to provide prospective evidence on the non-inferiority of ICG with NIR fluorescence imaging.Methods and analysis We initiated a prospective non-inferiority study with a paired comparison of both SLN methods in a single sample of 101 patients with International Federation of Gynecology and Obstetrics (FIGO) stage IA–IB2 or IIA1 cervical cancer receiving primary surgical treatment. All patients undergo SLN mapping with ICG and NIR fluorescence imaging in adjunct to mapping with 99mTc (including single photon emission computed tomography with X-ray computed tomography (SPECT/CT)) and blue dye. Surgeons start SLN detection with ICG while being blinded for the preoperative outcome of SPECT/CT to avoid biased detection with ICG. Primary endpoint of this study is bilateral SLN detection rate of both methods (ie, detection of at least one SLN in each hemipelvis). Since we compare strategies for SLN mapping that are already applied in current daily practice for different types of cancer, no additional risks or burdens are expected from these study procedures.Ethics and dissemination The current study is approved by the Medical Ethics Research Committee Utrecht (reference number 21–014). Findings arising from this study will be disseminated in peer-reviewed journals, academic conferences and through patient organisations.Trial registration number NL9011 and EudraCT 2020-005134-15.

Abstract

Abstract Molecular markers are suggested to improve the diagnostic and prognostic accuracy in patients with coronary artery disease (CAD) beyond current clinical scores based on age, gender, symptoms and traditional risk factors. In this context, plasma lipids are emerging as predictors of both plaque composition and risk of future events. We aim to identify plasma lipid biomarkers associated to CAD indexes of stenosis severity, plaque lipid content and a comprensive score of CAD extent and its risk. We used a simple high performance liquid chromatography-tandem mass spectrometry method to identify 69 plasma lipids in 132 subjects referred to Coronary Computed Tomography Angiography (CCTA) for suspected CAD, all under statin treatment. Patients were stratified in groups using three different CCTA-based annotations: CTA-risk score, lipid plaque prevalence (LPP) ratio and the coronary artery disease-reporting and data system (CAD-RADS). We identified a common set of lipid biomarkers composed of 7 sphingomyelins and 3 phosphatidylethanolamines, which discriminates between high risk CAD patients and controls regardless of the CAD annotations used (CTA score, LPP ratio, or CAD-RADS). These results highlight the potential of circulating lipids as biomarkers of stenosis severity, non calcified plaque composition and overall plaque risk of events.

Abstract

Abstract Sea surface temperature (SST) anomalies caused by a warm core eddy (WCE) in the Southwestern Atlantic Ocean (SWA) rendered a crucial influence on modifying the marine atmospheric boundary layer (MABL). During the first cruise to support the Antarctic Modeling and Observation System (ATMOS) project, a WCE that was shed from the Brazil Current was sampled. Apart from traditional meteorological measurements, we used the Eddy Covariance method to directly measure the ocean–atmosphere sensible heat, latent heat, momentum, and carbon dioxide (CO2) fluxes. The mechanisms of pressure adjustment and vertical mixing that can make the MABL unstable were both identified. The WCE also acted to increase the surface winds and heat fluxes from the ocean to the atmosphere. Oceanic regions at middle and high latitudes are expected to absorb atmospheric CO2, and are thereby considered as sinks, due to their cold waters. Instead, the presence of this WCE in midlatitudes, surrounded by predominantly cold waters, caused the ocean to locally act as a CO2 source. The contribution to the atmosphere was estimated as 0.3 ± 0.04 mmol m−2 day−1, averaged over the sampling period. The CO2 transfer velocity coefficient (K) was determined using a quadratic fit and showed an adequate representation of ocean–atmosphere fluxes. The ocean–atmosphere CO2, momentum, and heat fluxes were each closely correlated with the SST. The increase of SST inside the WCE clearly resulted in larger magnitudes of all of the ocean–atmosphere fluxes studied here. This study adds to our understanding of how oceanic mesoscale structures, such as this WCE, affect the overlying atmosphere.

Abstract

Abstract The ability to identify specific cell–cell contact in the highly heterogeneous mammalian body is crucial to revealing precise control of the body plan and correct function. To visualize local connections, we previously developed a genetically encoded fluorescent indicator, GRAPHIC, which labels cell–cell contacts by restricting the reconstituted green fluorescent protein (GFP) signal to the contact site. Here, we modify GRAPHIC to give the reconstituted GFP motility within the membrane, to detect cells that make contact with other specific cells. Removal of leucine zipper domains, located between the split GFP fragment and glycophosphatidylinositol anchor domain, allowed GFP reconstituted at the contact site to diffuse throughout the entire plasma membrane, revealing cell morphology. Further, depending on the structural spacers employed, the reconstituted GFP could be selectively targeted to N terminal (NT)- or C terminal (CT)-probe-expressing cells. Using these novel constructs, we demonstrated that we can specifically label NT-probe-expressing cells that made contact with CT-probe-expressing cells in an epithelial cell culture and in Xenopus 8-cell-stage blastomeres. Moreover, we showed that diffusible GRAPHIC (dGRAPHIC) can be used in neuronal circuits to trace neurons that make contact to reveal a connection map. Finally, application in the developing brain demonstrated that the dGRAPHIC signal remained on neurons that had transient contacts during circuit development to reveal the contact history. Altogether, dGRAPHIC is a unique probe that can visualize cells that made specific cell–cell contact.

Abstract

There is mounting evidence that microbes residing in the human intestine contribute to diverse alcohol-associated liver diseases (ALD) including the most deadly form known as alcohol-associated hepatitis (AH). However, mechanisms by which gut microbes synergize with excessive alcohol intake to promote liver injury are poorly understood. Furthermore, whether drugs that selectively target gut microbial metabolism can improve ALD has never been tested. We used liquid chromatography tandem mass spectrometry to quantify the levels of microbe and host choline co-metabolites in healthy controls and AH patients, finding elevated levels of the microbial metabolite trimethylamine (TMA) in AH. In subsequent studies, we treated mice with non-lethal bacterial choline TMA lyase (CutC/D) inhibitors to blunt gut microbe-dependent production of TMA in the context of chronic ethanol administration. Indices of liver injury were quantified by complementary RNA sequencing, biochemical, and histological approaches. In addition, we examined the impact of ethanol consumption and TMA lyase inhibition on gut microbiome structure via 16S rRNA sequencing. We show the gut microbial choline metabolite TMA is elevated in AH patients and correlates with reduced hepatic expression of the TMA oxygenase flavin-containing monooxygenase 3 (FMO3). Provocatively, we find that small molecule inhibition of gut microbial CutC/D activity protects mice from ethanol-induced liver injury. CutC/D inhibitor-driven improvement in ethanol-induced liver injury is associated with distinct reorganization of the gut microbiome and host liver transcriptome. The microbial metabolite TMA is elevated in patients with AH, and inhibition of TMA production from gut microbes can protect mice from ethanol-induced liver injury.

Abstract

In this study we sought to explore the association between preschool instructional approach and health and well-being at age 35 for a large sample of low-income children. Participants included 989 low-income, minority children who attended Child-Parent Center preschools as part of the Chicago Longitudinal Study from 1983 to 1985. Preschool curriculum was obtained from teacher reports and validated by program evaluators. These data were categorized by raters as: high teacher-directed and child-initiated; low teacher-directed and child-initiated; low teacher-directed and high child-initiated; or high teacher-directed and low child-initiated. Data on adult outcomes were obtained through surveys and administrative records. Those in preschool classrooms with high teacher-directed and child-initiated instruction had increased odds of having a livable wage (Odds Ratio(OR) = 2.02, p = 0.001), and decreased odds of felony arrest (OR = 0.39; p

Abstract

Simple Summary: In the past decades, the survival of ovarian malignant tumors has been largely unchanged. Treatment usually consists of a combination of systemic and surgical therapy. However, when recurrence occurs, treatment options are limited. When repeated surgery is no longer possible and chemotherapy is no longer effective, theranostics, a newly developing approach, might be of value. Theranostics will diagnose and destroy malignant tissue by binding radioactive isotopes to targets on malignant cells. To develop this approach, selection and validation of a target is necessary. For the selection of a target in ovarian tumors, the follicle-stimulating hormone (FSH) receptor appears to be suitable because it is primarily expressed in ovarian tissue, and expression is reported in malignant tumors. This review seeks to determine whether the follicle-stimulating hormone receptor is expressed in ovarian tumor types and, therefore, is suitable as a target in a future theranostic approach. Ovarian cancer mortality rates have not decreased significantly in the past years. As most women are still diagnosed in an advanced stage, there is a need for new treatment strategies for recurrent disease. A potentially new developing targeted approach, theranostics, combines diagnostics and treatment using radiopharmaceuticals. Through target receptors, imaging and treatment of malignant tissue can be achieved. For ovarian malignancy, the follicle-stimulating hormone (FSH) receptor may serve as a possible target since expression appears to be limited to ovarian cells. In this systematic review, we aim to gather all available literature on the expression of the FSH receptor in ovarian tumors. Pubmed, Embase and the Cochrane databases were searched until December 2023 for eligible studies. The search yielded 41 studies, mostly regarding serous carcinomas, sex cord–stromal tumors (SCSTs) and cell lines of serous and SCSTs. Various techniques were used to analyze the expression of the FSH receptor. For serous carcinomas, conflicting results on the expression of the FSH receptor were found. Studies on SCSTs, mainly studying the subtype of granulosa cell tumors, all showed positive expression of the FSH receptor. In the cell lines studies, the KGN cell line derived from a granulosa cell tumor shows positive expression in all studies. Available studies show that SCSTs express the FSH receptor. A theranostic approach targeting the FSH receptor may, therefore, provide a useful new approach for this malignancy with limited therapeutic options in recurrent disease. [ABSTRACT FROM AUTHOR]

Abstract

Hepatocellular death contributes to progression of alcohol–associated (ALD-associated) and non–alcohol-associated (NAFL/NASH) liver diseases. However, receptor-interaction protein kinase 3 (RIP3), an intermediate in necroptotic cell death, contributes to injury in murine models of ALD but not NAFL/NASH. We show here that a differential role for mixed-lineage kinase domain–like protein (MLKL), the downstream effector of RIP3, in murine models of ALD versus NAFL/NASH and that RIP1-RIP3-MLKL can be used as biomarkers to distinguish alcohol-associated hepatitis (AH) from NASH. Phospho-MLKL was higher in livers of patients with NASH compared with AH or healthy controls (HCs). MLKL expression, phosphorylation, oligomerization, and translocation to plasma membrane were induced in WT mice fed diets high in fat, fructose, and cholesterol but not in response to Gao-binge (acute on chronic) ethanol exposure. Mlkl–/– mice were not protected from ethanol-induced hepatocellular injury, which was associated with increased expression of chemokines and neutrophil recruitment. Circulating concentrations of RIP1 and RIP3, but not MLKL, distinguished patients with AH from HCs or patients with NASH. Taken together, these data indicate that MLKL is differentially activated in ALD/AH compared with NAFL/NASH in both murine models and patients. Furthermore, plasma RIP1 and RIP3 may be promising biomarkers for distinguishing AH and NASH.

Abstract

Tuta absoluta is one of the most damaging pests of tomato crops worldwide. Damage due to larvae may cause up to 100% loss of tomato production. Use of natural enemies to control the pest, notably predatory mirids such as Nesidiocoris tenuis and Macrolophus pygmaeus, is increasingly being promoted. However, considering the potential damage caused to tomatoes by these omnivorous predators in the absence of T. absoluta, an alternative solution could be required to reduce tomato damage and improve the predators' performance. The use of companion plants can be an innovative solution to cope with these issues. The present study aimed to determine the influence of companion plants and alternative preys on the predators' performance in controlling T. absoluta and protecting tomato plants. We evaluated the effect of predators (alone or combined) and a companion plant (sesame (Sesamum indicum)) on T. absoluta egg predation and crop damage caused by N. tenuis. The influence of an alternative prey (Ephestia kuehniella eggs) on the spatial distribution of predators was also evaluated by caging them in the prey presence or absence, either on tomato or sesame plants or on both. We found that the presence of sesame did not reduce the efficacy of N. tenuis or M. pygmaeus in consuming T. absoluta eggs; hatched egg proportion decreased when N. tenuis, M. pygmaeus, or both predators were present. More specifically, this proportion was more strongly reduced when both predators were combined. Sesame presence also reduced necrotic rings caused by N. tenuis on tomato plants. Nesidiocoris tenuis preferred sesame over tomato plants (except when food was provided only on the tomato plant) and the upper part of the plants, whereas M. pygmaeus preferred tomato to sesame plants (except when food was provided only on the sesame plant) and had no preference for a plant part. Combination of predators N. tenuis and M. pygmaeus allows for better coverage of cultivated plants in terms of occupation of different plant parts and better regulation of T. absoluta populations. Sesamum indicum is a potential companion plant that can be used to significantly reduce N. tenuis damage to tomatoes.

Abstract

Filoviruses (Family Filoviridae genera Ebolavirus and Marburgvirus) are negative-stranded RNA viruses that cause severe health effects in humans and non-human primates, including death. Except in outbreak settings, vaccines and other medical countermeasures against Ebola virus (EBOV) will require testing under the FDA Animal Rule. Multiple vaccine candidates have been evaluated using cynomolgus monkeys (CM) exposed to EBOV Kikwit strain. To the best of our knowledge, however, animal model development data supporting the use of CM in vaccine research have not been submitted to the FDA. This study describes a large CM database (122 CM, 62 female and 60 male, age 2 to 9 years) and demonstrates the consistency of the CM model through time to death models and descriptive statistics. CMs were exposed to EBOV doses of 0.1 to 100,000 PFU in 33 studies conducted at three Animal Biosafety Level 4 facilities, by three exposure routes. Time to death was modeled using Cox proportional hazards models with a frailty term that incorporated study-to-study variability. Despite significant differences attributed to exposure variables, all CMs exposed to the 100 to 1,000 pfu doses commonly used in vaccine studies died or met euthanasia criteria within 21 days of exposure, median 7 days, 93% between 5 and 12 days of exposure. Moderate clinical signs were observed 4 to 5 days after exposure and preceded death or euthanasia by approximately one day. Viremia was detected within a few days of infection. Hematology indices were indicative of viremia and the propensity for hemorrhage with progression of Ebola viremia. Changes associated with coagulation parameters and platelets were consistent with coagulation disruption. Changes in leukocyte profiles were indicative of an acute inflammatory response. Increased liver enzymes were observed shortly after exposure. Taken together, these factors suggest that the cynomolgus monkey is a reliable animal model for human disease.

Abstract

Levels of protein translation by ribosomes are governed both by features of the translation machinery as well as sequence properties of the mRNAs themselves. We focus here on a striking three-nucleotide periodicity, characterized by overrepresentation of GCN codons and underrepresentation of G at the second position of codons, that is observed in Open Reading Frames (ORFs) of mRNAs. Our examination of mRNA sequences in Saccharomyces cerevisiae revealed that this periodicity is particularly pronounced in the initial codons—the ramp region—of ORFs of genes with high protein expression. It is also found in mRNA sequences immediately following non-standard AUG start sites, located upstream or downstream of the standard annotated start sites of genes. To explore the possible influences of the ramp GCN periodicity on translation efficiency, we tested edited ramps with accentuated or depressed periodicity in two test genes, SKN7 and HMT1. Greater conformance to (GCN)n was found to significantly depress translation, whereas disrupting conformance had neutral or positive effects on translation. Our recent Molecular Dynamics analysis of a subsystem of translocating ribosomes in yeast revealed an interaction surface that H-bonds to the +1 codon that is about to enter the ribosome decoding center A site. The surface, comprised of 16S/18S rRNA C1054 and A1196 (E. coli numbering) and R146 of ribosomal protein Rps3, preferentially interacts with GCN codons, and we hypothesize that modulation of this mRNA-ribosome interaction may underlie GCN-mediated regulation of protein translation. Integration of our expression studies with large-scale reporter studies of ramp sequence variants suggests a model in which the C1054-A1196-R146 (CAR) interaction surface can act as both an accelerator and braking system for ribosome translation.

Abstract

Modulation of gene activity by creating mutations has contributed significantly to the understanding of protein functions. Oftentimes, however, mutational analyses use overexpression studies, in which proteins are taken out of their normal contexts and stoichiometries. In the present work, we sought to develop an approach to simultaneously use the CRISPR/Cas9 and Cre-Lox techniques to modify the endogenous SAT1 gene to introduce mutant forms of the protein while still under the control of its natural gene promoter. We cloned the C-terminal portion of wild type (WT) SAT1, through the transcriptional stop elements, and flanked by LoxP sites in front of an identical version of SAT1 containing point mutations in critical binding sites. The construct was inserted into the endogenous SAT1 locus by Non-Homologous End Joining (NHEJ) after a CRISPR/Cas9 induced DNA double strand break. After validating that normal function of SAT1 was not altered by the insertional event, we were then able to assess the impact of point mutations by introduction of Cre recombinase. The system thus enables generation of cells in which endogenous WT SAT1 can be conditionally modified, and allow investigation of the functional consequences of site specific mutations in the context of the normal promoter and chromatin regulation.

Abstract

Abstract Ebola virus (EBOV) is a negative-strand RNA virus that replicates in the cytoplasm and causes an often-fatal hemorrhagic fever. EBOV, like other viruses, can reportedly encode its own microRNAs (miRNAs) to subvert host immune defenses. miRNAs are short noncoding RNAs that can regulate gene expression by hybridizing to multiple mRNAs, and viral miRNAs can enhance viral replication and infectivity by regulating host or viral genes. To date, only one EBOV miRNA has been examined in human infection. Here, we assayed mouse, rhesus macaque, cynomolgus macaque, and human samples infected with three EBOV variants for twelve computationally predicted viral miRNAs using RT-qPCR. Ten miRNAs aligned to EBOV variants and were detectable in the four species during disease with several viral miRNAs showing presymptomatic amplification in animal models. miRNA abundances in both the mouse and nonhuman primate models mirrored the human cohort, with miR-1-5p, miR-1-3p, and miR-T3-3p consistently at the highest levels. These striking similarities in the most abundant miRNAs during infection with different EBOV variants and hosts indicate that these miRNAs are potential valuable diagnostic markers and key effectors of EBOV pathogenesis.

Abstract

Abstract Single, double and triple doses of the synthetic insulins glargine and degludec currently used in patient therapy are characterised using macromolecular hydrodynamic techniques (dynamic light scattering and analytical ultracentrifugation) in an attempt to provide the basis for improved personalised insulin profiling in patients with diabetes. Using dynamic light scattering and sedimentation velocity in the analytical ultracentrifuge glargine was shown to be primarily dimeric under solvent conditions used in current formulations whereas degludec behaved as a dihexamer with evidence of further association of the hexamers (“multi-hexamerisation”). Further analysis by sedimentation equilibrium showed that degludec exhibited reversible interaction between mono- and-di-hexamer forms. Unlike glargine, degludec showed strong thermodynamic non-ideality, but this was suppressed by the addition of salt. With such large injectable doses of synthetic insulins remaining in the physiological system for extended periods of time, in some case 24–40 hours, double and triple dose insulins may impact adversely on personalised insulin profiling in patients with diabetes.

Abstract

Background Rotator cuff repair (RCR) is one of the most common elective orthopedic procedures with predictable indications, technique, and outcomes. As a result, this surgery is an ideal choice for studying value. The purpose of this study was to utilize Patient-level value-analysis (PLVA) within the setting of RCR over the one-year episode-of-care. Methods Included patients (n=396) underwent RCR between 2009 and 2016 at a single outpatient orthopedic surgery center. The episode-of-care was defined as one-year following surgery. The Western Ontario Rotator Cuff (WORC) index was collected at both the initial preoperative baseline and the one-year postoperative mark. The total cost-of-care was determined using time-driven activity-based costing (TDABC). Both patient (PLVA) and provider-level value-analysis (pLVA) were performed. Results The average TDABC cost-of-care was derived at $5413.78 ± $727.41 [$5341.92, $5485.64]. At the patient-level, arthroscopic isolated supraspinatus tears yielded the highest value coefficient, 0.82 (ANOVA F-Test, p=0.01). There was a poor correlation between the change in one-year WORC score and the TDABC cost-of-care (r2=0.03). Provider-level value demonstrated significant variation between the 8 evaluated providers (p Conclusion RCR is one of the most common orthopedic procedures, yet the correlations between cost-of-care and patient outcomes is unknown. PLVA quantifies the ratio of functional improvement to the TDABC estimated cost-of-care at the patient-level. This is the first study to apply patient-level value analysis over the first-year episode-of-care. With healthcare transitioning towards value-based delivery, PLVA offers a quantitative tool to measure the value of individual patient care delivery over the entire episode-of-care.

Abstract

Many kidney donor candidates with impaired fasting glucose (IFG) and all candidates with diabetes are currently excluded from kidney donation, fearing the development of an accelerated course of diabetic kidney disease in the remaining kidney.We studied mortality, proteinuria, and end-stage kidney disease (ESKD) in 8280 donors who donated between 1963 and 2007 according to donation fasting plasma glucose (FPG):100 mg/dL (n = 6204), 100-125 mg/dL (n = 1826), and ≥126 mg/dL (n = 250).Donors with IFG and those with FPG ≥126 mg/dL were older, less likely to be non-Hispanic White, had a higher body mass index, and were more likely to be related to their recipient. After 15.7 ± 10.5 y from donation to study close, 4.4% died, 29.4% developed hypertension, 13.8% developed proteinuria, and 41 (0.5%) developed ESKD. In both the logistic and Cox models, IFG was associated with a higher diabetes risk (adjusted hazard ratio [aHR], 1.65; 95% confidence interval [CI], 1.18-2.30) and hypertension (aHR, 1.35; 95% CI, 1.10-1.65; P = 0.003 for both), but not higher risk of proteinuria or ESKD. The multivariable risk of mortality in donors with ≥126 mg/dL was higher than the 2 other groups, but risks of proteinuria, cardiovascular disease, and reduced estimated glomerular filtration rate were similar to those with FPG126 mg/dL. Three cases of ESKD developed in the 250 donors with FPG ≥126 mg/dL at 18.6 ± 10.3 y after donation (aHR, 5.36; 95% CI, 1.0-27.01; P = 0.04).Donors with IFG and the majority of donors with ≥126 mg/dL do well and perhaps should not be routinely excluded from donation.

Abstract

Purpose The aim of this study was to examine current practice patterns in pediatric total body irradiation (TBI) techniques among COG member institutions. Methods and Materials Between November 2019 and February 2020, a questionnaire containing 52 questions related to the technical aspects of TBI was sent to medical physicists at 152 COG institutions. The questions were designed to obtain technical information on commonly used TBI treatment techniques. Another set of 9 questions related to the clinical management of patients undergoing TBI was sent to 152 COG member radiation oncologists at the same institutions. Results Twelve institutions were excluded because TBI was not performed in their institutions. A total of 88 physicists from 88 institutions (63% response rate) and 96 radiation oncologists from 96 institutions (69% response rate) responded. The anterior-posterior/posterior-anterior (AP/PA) technique was the most common technique reported (49 institutions [56%]); 44 institutions (50%) used the lateral technique, and 14 (16%) used volumetric modulated arc therapy or tomotherapy. Midplane dose rates of 6 to 15 cGy/min were most commonly used. The most common specification for lung dose was the midlung dose for both AP/PA techniques (71%) and lateral techniques (63%). Almost all physician responders agreed with the need to refine current TBI techniques, and 79% supported the investigation of new TBI techniques to further lower the lung dose. Conclusions There was no consistency in the practice patterns, methods for dose measurement, and reporting of TBI doses among COG institutions. The lack of standardization precludes meaningful correlation between TBI doses and clinical outcomes including disease control and normal tissue toxicity. The COG radiation oncology discipline is currently undertaking several steps to standardize the practice and dose reporting of pediatric TBI using detailed questionnaires and phantom-based credentialing for all COG centers.

Abstract

Radiation pneumonitis is a rare but possibly fatal side effect of Yttrium-90 (90Y) radioembolization. It may occur 1 to 6 months after therapy, in case a significant part of the 90Y microspheres shunt to the lungs. In current clinical practice, a predicted value of lung dose greater than 30Gy is considered a criterion to exclude patients from treatment. However, contrasting findings regarding the occurrence of radiation pneumonitis and lung dose were previously reported in literature. In this study, the relationship between the lung dose value and the eventual occurrence of radiation pneumonitis after 90Y radioembolization was investigated. Methods: A total of 317 90Y liver radioembolization procedures performed during an 8-years period (Feb.2012-Sep.2020) were retrospectively analyzed. Predicted lung mean dose using 99mTc-MAA planar scintigraphy (LMDMAA) acquired during the planning phase and left lung mean dose (LMDY-90) using the 90Y PET/CT acquired after the treatment were calculated. For the lung dose computation, it was chosen to use the left lung as representative lung volume, to compensate for the scatter from the liver moving in the cranial-caudal direction due to breathing and mainly affecting the right lung. Results: Two hundred and seventy-two patients underwent 90Y procedures, of which 63% performed with glass microspheres and 37% with resin microspheres. Median injected activity was 1974MBq (range: 242-9538MBq). Median LMDMAA was 3.5Gy (range: 0.2-89.0Gy). For 14 procedures LMDMAA was >30Gy. Median LMDY-90 was 1Gy (range: 0.0-22.1Gy). No patients had a LMDY-90 >30Gy. Of the three patients with a LMDY-90 >12Gy, two patients (LMDY-90 = 22.1Gy, LMDMAA = 89Gy and LMDY-90 = 17.7Gy, LMDMAA = 34.1Gy, respectively) developed radiation pneumonitis and consequently died. A third patient with a LMDY-90 equal to 18.4Gy (LMDMAA = 29.1Gy) died 2 months after treatment, before imaging evaluation, due to progressive disease. Conclusion: The occurrence of radiation pneumonitis as a consequence of lung shunt following 90Y radioembolization is rare (

Abstract

Women with valvular heart disease may be more likely to have adverse obstetric and cardiovascular complications during pregnancy. Most current recommendations focus on stenotic lesions with less guidance regarding regurgitant lesions. We aimed to compare adverse events at delivery for women with various stenotic and regurgitant valvular diseases. We used the 2016 to 2018 National Inpatient Sample data to compare demographics, comorbidities, and obstetric and cardiovascular complications during delivery hospitalizations. After adjusting for clinical and socioeconomic factors, logistic regression was performed to investigate associations between valvular disease and outcomes. Among >11.2 million deliveries, 20,349 were in women with valvular disease. Women with valvular disease were older, had longer length of stays, and higher costs associated with delivery. They had higher prevalence of underlying cardiovascular comorbidities compared with women without valvular disease (hypertension: 5.1 vs 0.25%; pulmonary hypertension: 7.0 vs

Abstract

Accumulating evidence now shows that supplemental antioxidants including vitamin C, vitamin E and N-Acetylcysteine consumption can suppress adaptations to endurance-type exercise by attenuating reactive oxygen and nitrogen species (RONS) formation within skeletal muscle. This emerging evidence points to the importance of pro-oxidation as an important stimulus for endurance-training adaptations, including mitochondrial biogenesis, endogenous antioxidant production, insulin signalling, angiogenesis and growth factor signaling. Although sustained oxidative distress is associated with many chronic diseases, athletes have, on average, elevated levels of certain endogenous antioxidants to maintain redox homeostasis. As a result, trained athletes may have a better capacity to buffer oxidants during and after exercise, resulting in a reduced oxidative eustress stimulus for adaptations. Thus, higher levels of RONS input and exercise-induced oxidative stress may benefit athletes in the pursuit of continuous endurance training redox adaptations. This review addresses why athletes should be looking to enhance exercise-induced oxidative stress and how it can be accomplished. Methods covered include high-intensity interval training, hyperthermia and heat stress, dietary antioxidant restriction and modified antioxidant timing, dietary antioxidants and polyphenols as adjuncts to exercise, and vitamin C as a pro-oxidant.

Abstract

Objective To evaluate intravenous scleral and intracameral aqueous angiography in normotensive (n = 4) and hypertensive glaucomatous (n = 6) ADAMTS10-mutant canine eyes. Animals studied Ten ADAMTS10-mutant dogs were used in this study. Procedures Dogs were sedated and one eye from each dog underwent scleral angiography following intravenous injection of 0.25% indocyanine green (ICG). After a 24-h recovery period, the same eye underwent aqueous angiography via intracameral administration of ICG. Imaging of identical scleral sectors from the same eye was performed using a Heidelberg Spectralis® Confocal Scanning Laser Ophthalmoscope. Intrascleral vessel depth and lumen diameters were measured using Heidelberg Spectralis® optical coherence tomography and computer software. Results Scleral angiography permitted visualization of vascular components associated with conventional aqueous humor outflow pathways with an average time from injection to fluorescence of 35.8 ± 10.6 s (mean ± SD). Two normotensive eyes (2/10;20%) demonstrated turbulent dye movement, while 4 hypertensive eyes (4/10;40%) exhibited laminar flow. Aqueous angiography demonstrated dye fluorescence within the post-trabecular conventional aqueous humor outflow pathways in all 10 eyes at 34.3 ± 11.0 s post-injection. Sectoral and dynamic outflow patterns were observed primarily within the superotemporal sector in nine eyes (9/10; 90%). Seven eyes (7/10; 70%) demonstrated pulsatile dye movement and five eyes (5/10; 50%) exhibited laminar flow. The degree of laminar movement of dye was greatest in hypertensive eyes. Vessel lumen diameters measured 133.85 ± 28.36 µm and 161.18 ± 6.02 µm in hypertensive and normotensive eyes, respectively. Conclusions Aqueous angiography allowed for visualization of fluorescent dye in the superotemporal sclera. Laminar flow and smaller lumen vessels were observed mainly in hypertensive eyes.

Abstract

Inverse dynamics is a technique in which measured kinematics and, possibly, external forces are used to calculate net joint torques in a rigid body linked segment model. However, kinematics and forces are usually not consistent due to incorrect modelling assumptions and measurement errors. This is commonly resolved by introducing 'residual forces and torques' which compensate for this problem, but do not exist in reality. In this study a constrained optimization algorithm is proposed that finds the kinematics that are mechanically consistent with measured external forces and mimic the measured kinematics as closely as possible. The algorithm was tested on datasets containing planar kinematics and ground reaction forces obtained during human walking at three velocities (0.8 m/s, 1.25 and 1.8 m/s). Before optimization, the residual force and torque were calculated for a typical example. Both showed substantial values, indicating the necessity of developing a mechanically consistent algorithm. The proposed optimization algorithm converged to a solution in which the residual forces and torques were zero, without changing the ground reaction forces and with only minor changes to the measured kinematics. When using a rigid body approach, our algorithm ensures a consistent description of forces and kinematics, thereby improving the validity of calculated net joint torque and power values.

Abstract

BACKGROUND Glomerular size in renal allografts is impacted by donor-recipient factors and response to injury. In serial biopsies of patients with well-functioning grafts, increased glomerular size correlates with better survival. However, no previous study has addressed the association of glomerular size at the time of a for-cause biopsy and clinical/histopathologic markers of injury, or effect on long-term graft outcome. METHODS Two cohorts of kidney transplant recipients enrolled in the Deterioration of Kidney Allograft Function study were evaluated. The prospective cohort (PC, n = 581): patients undergoing first for-cause kidney biopsy 1.7 ± 1.4 (mean ± SD) y posttransplant; and the cross-sectional cohort (CSC, n = 446): patients developing new-onset renal function deterioration 7.7 ± 5.6 y posttransplant. Glomerular planar surface area and diameter were measured on all glomeruli containing a vascular pole. Kidney biopsy was read centrally in a blinded fashion according to the Banff criteria. RESULTS Glomerular area was significantly higher in the CSC than the PC; time from transplant to indication biopsy was associated with glomerular area in both cohorts (P values ≤ 0.001). Glomerular area was associated with indices of microvascular inflammation (glomerulitis, peritubular capillary infiltrates; P values ≤ 0.001) and segmental glomerulosclerosis (P value < 0.0001). In the CSC, higher glomerular area was associated with higher estimated glomerular filtration rate (P value ≤ 0.001) and increased graft survival after accounting for microvascular inflammation (adjusted hazard ratio = 0.967; 95% confidence interval: 0.948-0.986; hazard ratio in biopsies without evidence of diabetes or antibody mediated rejection = 0.919, 95% confidence interval: 0.856-0.987). CONCLUSIONS Glomerular size is associated with histopathologic features present at the time of indication biopsy and with increased graft survival in the CSC.

Abstract

INTRODUCTION The digital age and global pandemic have transformed the way patients select their plastic surgeon. However, as more patients turn to online resources, there is little information on the digital presence of academic plastic surgeons. METHODS We identified all academic faculty from integrated and independent plastic surgery residency programs. Using a Google-based custom search, the top 10 search results for each surgeon were extracted and categorized as surgeon noncontrolled (eg, physician rating websites) or controlled (eg, social media, institutional, and research profiles). RESULTS Eight hundred four academic plastic surgeons were included. Most search results were surgeon-noncontrolled sites (57%, n = 4547). Being male (odds ratio [OR], 0.60, P = 0.0020) and holding a higher academic rank (OR = 0.61, P < 0.0001) significantly decreased the prevalence of physician rating websites, whereas career length was significantly associated with a greater number of rating websites (OR = 1.04, P < 0.0001). Surgeon-controlled websites were significantly influenced by academic rank and years in practice; higher academic rank was associated with more social media platforms (OR = 1.42, P = 0.0008), institutional webpages (OR = 1.57, P < 0.0001), and research profiles (OR = 1.62, P = 0.0008). Conversely, longer career duration was a predictor for fewer social media platforms (OR = 0.95, P < 0.0001) and institutional webpages (OR = 0.95, P < 0.0001). CONCLUSIONS Academic plastic surgeons do not hold control of the majority of their search results. However, digitally savvy plastic surgeons can focus attention by building on certain areas to optimize their digital footprint. This study can serve as a guide for academic plastic surgeons wishing to control their online presence.

Abstract

Background There are limited data regarding the factors associated with hepatocellular carcinoma (HCC) in non-alcoholic fatty liver disease (NAFLD) patients without cirrhosis. We sought to determine the prevalence and factors associated with HCC in NAFLD patients with or without cirrhosis. Methods Adults with NAFLD (June 2015 to May 2020) were identified using the electronic health record database (Explorys Inc, Cleveland, OH) from 26 major integrated US healthcare systems. The prevalence of HCC was calculated. Multivariable analyses adjusting for covariates were performed to evaluate the associated risk factors and the presence of HCC. Results A total of 392,800 NAFLD patients were identified. Among 1110 patients with HCC, 170 (15.3%) had no cirrhosis. The prevalence of HCC in non-cirrhotic and cirrhotic NAFLD patients was 4.6/10,000 persons (95% CI 3.9–5.3), and 374.4/10,000 persons (95% CI 350.9–398.8), respectively. Age > 65 years (adjusted OR; 3.37, 95% CI 2.47–4.59), ever had elevated alanine aminotransferase (2.69; 2.14–3.37), male gender (2.57; 1.88–3.49), smoker (1.75; 1.23–2.49), and diabetes (1.56; 1.15–2.11) were associated with HCC in non-cirrhotic NAFLD (all P 65 years, male gender, Hispanic race, elevated alanine aminotransferase, diabetes and smoker (all P Conclusions These data identified the major risk factors for the development of HCC in NAFLD patients. In the non-cirrhotics, older male patients with smoking history, diabetes and an elevated alanine aminotransferase had highest risk and may need increased judicious monitoring.

Abstract

The intervertebral disc (IVD) annulus fibrosus (AF) is composed of concentric lamellae with alternating right- and left-handed helically oriented collagen fiber bundles. This arrangement results in anisotropic material properties, which depend on local fiber orientations. Prior measurements of fiber inclination angles in human lumbar and bovine caudal IVDs found a significantly higher inclination angle in the inner AF than outer, though it is currently unknown if this pattern is conserved in smaller mammalian species. Additionally, the physical mechanism behind this pattern remains un-determined. In this study, AF fiber angles were measured histologically in murine caudal IVDs and compared to previously published values from bovine caudal IVDs. Fiber angles were also predicted using three theoretical models, including two based on adaptation to internal swelling pressure and one based on vertebral body growth. Fiber angle was found to significantly decrease from 49.5 ± 3.8° in the inner AF to 34.5 ± 6.6° in the outer AF. While steeper than in bovine discs at all locations, the trend with radial position was comparable between species. This trend was best fit by growth-based model and opposite of that predicted by the pressure vessel models. Trends in AF fiber orientation are conserved between mammalian species. Modeling results suggest that the AF tissue microstructure is more likely to be driven by adjacent vertebral body growth than adapted for optimal mechanical performance.

Abstract

Severe maternal morbidity and mortality continue to increase in the United States, largely owing to chronic and newly diagnosed medical comorbidities. Interconception care, or care and management of medical conditions between pregnancies, can improve chronic disease control before, during, and after pregnancy. It is a crucial and time-sensitive intervention that can decrease maternal morbidity and mortality and improve overall health. Despite these potential benefits, interconception care has not been well implemented by the primary care community. Furthermore, there is a lack of guidelines for optimizing preconception chronic disease, risk stratifying postpartum chronic diseases, and recommending general collaborative management principles for reproductive-age patients in the period between pregnancies. As a result, many primary care providers, especially those without obstetric training, are unclear about their specific role in interconception care and may be unsure of effective methods for collaborating with obstetric care providers. In particular, internal medicine physicians, the largest group of primary care physicians, may lack sufficient clinical exposure to medical conditions in the obstetric population during their residency training and may feel uncomfortable in caring for these patients in their subsequent practice. The objective of this article is to review concepts around interconception care, focusing specifically on preconception care for patients with chronic medical conditions (eg, chronic hypertension, chronic diabetes mellitus, chronic kidney disease, venous thromboembolism, and obesity) and postpartum care for those with medically complicated pregnancies (eg, hypertensive disorders of pregnancy, gestational diabetes mellitus, excessive gestational weight gain, peripartum cardiomyopathy, and peripartum mood disorders). We also provide a pragmatic checklist for preconception and postpartum management.

Abstract

Purpose To review the current published literature on the use of OCT angiography (OCTA) to help detect changes associated with the diagnosis of primary open-angle glaucoma. Methods Searches of the peer-reviewed literature were conducted in March 2018, June 2018, April 2019, December 2019, and June 2020 in the PubMed and Cochrane Library databases. Abstracts of 459 articles were examined to exclude reviews and non-English articles. After inclusion and exclusion criteria were applied, 75 articles were selected and the panel methodologist rated them for strength of evidence. Three articles were rated level I and 57 articles were rated level II. The 15 level III articles were excluded. Results OCT angiography can detect decreased capillary vessel density within the peripapillary nerve fiber layer (level II) and macula (level I and II) in patients with suspected glaucoma, preperimetric glaucoma, and perimetric glaucoma. The degree of vessel density loss correlates significantly with glaucoma severity both overall and topographically (level II) as well as longitudinally (level I). For differentiating glaucomatous from healthy eyes, some studies found that peripapillary and macular vessel density measurements by OCTA show a diagnostic ability (area under the receiver operating characteristic curve) that is comparable with structural OCT retinal nerve fiber and ganglion cell thickness measurements, whereas other studies found that structural OCT measurements perform better. Choroidal or deep-layer microvasculature dropout as measured by OCTA is also associated with glaucoma damage (level I and II). Lower peripapillary and macular vessel density and choroidal microvasculature dropout are associated with faster rates of disease progression (level I and II). Conclusions Vessel density loss associated with glaucoma can be detected by OCTA. Peripapillary, macular, and choroidal vessel density parameters may complement visual field and structural OCT measurements in the diagnosis of glaucoma.

Abstract

The purpose of our study was to evaluate the factors that influence the timing of definitive fixation in the management of bilateral femoral shaft fractures and the outcomes for patients with these injuries.Patients with bilateral femur fractures treated between 1998 to 2019 at ten level-1 trauma centers were retrospectively reviewed. Patients were grouped into early or delayed fixation, which was defined as definitive fixation of both femurs within or greater than 24 hours from injury, respectively. Statistical analysis included reversed logistic odds regression to predict which variable(s) was most likely to determine timing to definitive fixation. The outcomes included age, sex, high-volume institution, ISS, GCS, admission lactate, and admission base deficit.Three hundred twenty-eight patients were included; 164 patients were included in the early fixation group and 164 patients in the delayed fixation group. Patients managed with delayed fixation had a higher Injury Severity Score (26.8 vs 22.4; p0.01), higher admission lactate (4.4 and 3.0; p0.01), and a lower Glasgow Coma Scale (10.7 vs 13; p0.01). High-volume institution was the most reliable influencer for time to definitive fixation, successfully determining 78.6% of patients, followed by admission lactate, 64.4%. When all variables were evaluated in conjunction, high-volume institution remained the strongest contributor (XIn this study, high-volume institution was the strongest predictor of timing to definitive fixation in patients with bilateral femur fractures. This study demonstrates an opportunity to create a standardized care pathway for patients with these injuries.Level III.

Abstract

Soft tissue wounds in the scalp are a common occurrence after trauma or resection of a malignancy. The reconstructive surgeon should strive to use the simplest reconstructive technique while optimizing aesthetic outcomes. In general, large defects with infection, previous irradiation (or require postoperative radiation), or with calvarial defects usually require reconstruction with vascularized tissue (ie, microvascular free tissue transfer). Smaller defects greater than 3 cm that are not amenable to primary closure can be treated with local flap reconstruction. In all cases, the reconstruction method will need be tailored to the patient's health status, desires, and aesthetic considerations.

Abstract

PurposeTo assess the feasibility of needle arthroscopy for management of suspected bacterial arthritis in native joints.MethodsDuring a pilot period, patients presenting with symptoms suggestive of native joint bacterial arthritis were eligible for initial management with needle arthroscopy. Procedures were performed in the operating theatre or at the patient bedside in the emergency department or inpatient ward. As our primary outcome measure, it was assessed whether needle arthroscopic lavage resulted in a clear joint. In addition, the need for conversion to standard arthroscopy or arthrotomy, the need for conversion from local to general anaesthesia, complications and the need for additional surgical intervention at follow-up during admission were recorded.ResultsEleven joints in 10 patients (four males, age range 35 – 77) were managed with needle arthroscopy. Needle arthroscopic lavage resulted in a clear joint in all cases. Conversion to standard arthroscopy or arthrotomy was not needed. Seven procedures were performed at the patient bedside using local anaesthesia. These procedures were well tolerated and conversion to general or spinal anaesthesia was not required. There were no procedure complications. One patient received multiple needle arthroscopic lavages. No further surgical interventions beside the initial needle arthroscopic lavage were required for successful management in other cases.ConclusionsNeedle arthroscopy can be a feasible tool in the initial management of complaints suggestive for native joint bacterial arthritis, providing an effective, quick and well-tolerable intervention in the operating theatre or at the patient bedside, with the potential to relief health systems from need for scarce operating theatre time.

Abstract

Summary The objective of this study was to review the antifungal susceptibility of clinical mould isolates performed by the New Zealand Mycology Reference Laboratory. Isolates were either local or referred for testing from other New Zealand laboratories. All isolates were tested by the broth colorimetric microdilution method, Sensititre YeastOne (SYO). Epidemiological cut-off values (ECVs) derived from either the Clinical and Laboratory Standards Institute (CLSI) method or SYO were used to determine the proportion of non-wild type (non-WT) isolates, i.e., those with an increased likelihood to harbour acquired mechanisms of resistance. A total of 614 isolates were tested. Most isolates (55%) were from the respiratory tract followed by musculoskeletal tissue (17%), eye (10%) and abdomen (5%). The azoles had similar activity except for voriconazole which was less active against the Mucorales. The echinocandins had good activity against Aspergillus spp., other hyaline moulds and dematiaceous isolates but were inactive against Fusarium spp., Lomentospora prolificans and the Mucorales. Amphotericin B had best activity against the Mucorales. The two least susceptible groups were Fusarium spp. and L. prolificans isolates. Three Aspergillus isolates were non-WT for amphotericin B, and four non-WT for azoles. Non-WT were not encountered for caspofungin. Non-Aspergillus isolates in New Zealand have susceptibility patterns similar to those reported elsewhere. In contrast to a growing number of other countries, azole resistance was rare in A. fumigatus sensu stricto. Non-WT isolates were uncommon. The results provide a baseline for monitoring emerging antifungal resistance in New Zealand and support current Australasian treatment guidelines for invasive fungal infections.

Abstract

Women with pregnancy-induced hypertension, defined as gestational hypertension and preeclampsia/eclampsia, are at increased risk of long-term cardiovascular disease, but less is known about the spectrum of acute cardiovascular outcomes, especially across racial/ethnic groups. We evaluated the risk of cardiovascular events at delivery associated with gestational hypertension and preeclampsia/eclampsia, compared with no pregnancy-induced hypertension, overall and by race/ethnicity. We used the 2016 to 2018 National Inpatient Sample data.International Classification of Diseases,Tenth Revision, Clinical Modification codes identified delivery hospitalizations and clinical diagnoses. Using survey weights, cardiovascular events were examined using logistic regression by pregnancy-induced hypertension status, with subsequent stratification by race/ethnicity. Among 11 304 996 deliveries in 2016 to 2018, gestational hypertension occurred in 614 995 (5.4%) and preeclampsia in 593 516 (5.2%). Black women had higher odds for preeclampsia independent of underlying comorbidities (adjusted odds ratio, 1.45 [95% CI, 1.42–1.49]) and had the highest rates for several complications (peripartum cardiomyopathy, 506; heart failure, 660; acute renal failure, 953; and arrhythmias, 418 per 100 000 deliveries). After adjustment for socioeconomic factors and comorbidities, preeclampsia/eclampsia was associated with increased risk of cardiovascular events in women of all races/ethnicities. However, risk was highest among Asian/Pacific Islander women and lowest among Black women. In sum, while Black women were the most likely to experience preeclampsia, Asian/Pacific women were the most at risk for acute cardiovascular complications during delivery hospitalization.

Abstract

Background Epithelial ovarian cancer (EOC) is often diagnosed late, with a 5-year relative survival of 30.2% for patients with metastatic disease. Residual disease following cytoreductive surgery is an important predictor for poor survival. EOC is characterized by diffuse peritoneal metastases and depositions of small size, challenging a complete resection. Targeted fluorescence imaging is a technique to enhance tumor visualization and can be performed intraoperatively. Folate receptor alpha (FRα) and human epidermal growth factor receptor 2 (HER2) are overexpressed in EOC in 80% and 20% of the cases, respectively, and have been previously studied as a target for intraoperative imaging. Objective To systematically review the literature on the feasibility of FRα and HER2 targeted fluorescence-guided cytoreductive surgery (FGCS) in women with EOC. Methods PubMed and Embase were searched for human and animal studies on FGCS targeting either HER2 or FRα in either women with EOC or animal models of EOC. Risk of bias and methodological quality were assessed with the SYRCLE and MINORS tool, respectively. Results All animal studies targeting either FRα or HER2 were able to detect tumor deposits using intraoperative fluorescence imaging. One animal study targeting HER2 compared conventional cytoreductive surgery (CCS) to FGCS and concluded that FGCS, either without or following CCS, resulted in statistically significant less residual disease compared to CCS alone. Human studies on FGCS showed an increased detection rate of tumor deposits. True positives ranged between 75%–77% and false positives between 10%–25%. Lymph nodes were the main source of false positive results. Sensitivity was 85.9%, though only reported by one human study. Conclusion FGCS targeting either HER2 or FRα appears to be feasible in both EOC animal models and patients with EOC. FGCS is a promising technique, but further research is warranted to validate these results and particularly study the survival benefit.

Abstract

BACKGROUND: Among patients with stable coronary disease and moderate or severe ischemia, whether clinical outcomes are better in those who receive an invasive intervention plus medical therapy than in those who receive medical therapy alone is uncertain. METHODS: We randomly assigned 5179 patients with moderate or severe ischemia to an initial invasive strategy (angiography and revascularization when feasible) and medical therapy or to an initial conservative strategy of medical therapy alone and angiography if medical therapy failed. The primary outcome was a composite of death from cardiovascular causes, myocardial infarction, or hospitalization for unstable angina, heart failure, or resuscitated cardiac arrest. A key secondary outcome was death from cardiovascular causes or myocardial infarction. RESULTS: Over a median of 3.2 years, 318 primary outcome events occurred in the invasive-strategy group and 352 occurred in the conservative-strategy group. At 6 months, the cumulative event rate was 5.3% in the invasive-strategy group and 3.4% in the conservative-strategy group (difference, 1.9 percentage points; 95% confidence interval [CI], 0.8 to 3.0); at 5 years, the cumulative event rate was 16.4% and 18.2%, respectively (difference, -1.8 percentage points; 95% CI, -4.7 to 1.0). Results were similar with respect to the key secondary outcome. The incidence of the primary outcome was sensitive to the definition of myocardial infarction; a secondary analysis yielded more procedural myocardial infarctions of uncertain clinical importance. There were 145 deaths in the invasive-strategy group and 144 deaths in the conservative-strategy group (hazard ratio, 1.05; 95% CI, 0.83 to 1.32). CONCLUSIONS: Among patients with stable coronary disease and moderate or severe ischemia, we did not find evidence that an initial invasive strategy, as compared with an initial conservative strategy, reduced the risk of ischemic cardiovascular events or death from any cause over a median of 3.2 years. The trial findings were sensitive to the definition of myocardial infarction that was used.

Abstract

There are several choices for induction immunosuppression in kidney-after-liver transplantation. We examined the impact of induction type on kidney graft and patient survival in kidney-after-liver recipients. We utilized the Scientific Registry of Transplant Recipients (SRTR) database and included patients transplanted between 1/1/2000 and 7/31/2017 to study kidney graft and patient outcomes of all kidney-after-liver transplant recipients in the United States. We only included those who were discharged on tacrolimus and mycophenolate with or without steroids and who had a negative crossmatch prior to kidney engraftment. We grouped recipients by kidney induction type into three groups: depletional (N=550), non-depletional (n=434), and no antibody induction (n=144). We studied patient and kidney allograft survival using Cox PH regression, with transplant center included as a random effect. Models were adjusted for liver induction regimen, recipient and donor age, gender, Human Leukocyte Antigen (HLA) mismatches, payor type, live-donor kidney transplant, dialysis status, time from liver engraftment, hepatitis C status, and the presence of diabetes mellitus at time of kidney transplant and transplant year. Six-month and one-year rejection rates did not differ between groups. In the multivariable models, as compared to no induction, neither depletional nor non-depletional induction was associated with improved recipient or graft survival. Depletional induction at the time of liver transplantation was associated with worse patient survival after kidney transplant [HR 1.71, 95%C.I. (1.09, 2.67), P 0.02]. Live-donor kidney transplantation was associated with a 48.1% improved graft survival [HR 0.52, 95%C.I. (0.33, 0.82), P 0.00]. In conclusion, in the settings of a negative crossmatch and maintenance with tacrolimus and mycophenolate, induction use was not associated with a patient or graft survival benefit in kidney after liver transplants.

Abstract

Background : : Five to ten percent of all patients undergoing radiofrequency ablation (RFA), which is the most established technique for Barrett's esophagus (BE) ablation-develop strictures. Hybrid-argon plasma coagulation (APC) combines APC with submucosal saline injection that was recently developed to tackle this problem. The aims of this pilot study were to evaluate the feasibility, tolerance, safety and long-term efficacy of hybrid-APC for the treatment of BE. Methods : : Patients with histological proven BE were selected for hybrid-APC. Prior to APC thermal ablation the mucosa was lifted using a submucosal high-pressure water jet injection system (Erbejet 2; Erbe, Tuebingen, Germany). Short-term (< 48 hours) and long-term (> 48 hours) safety were evaluated. Efficacy of ablation was measured at 3, 6, 12 and 24 months at follow-up endoscopy by evidence of macroscopically complete resolution of BE mucosa and/or histologically complete resolution of intestinal metaplasia (CRIM). Results : : Eleven patients were included in the study (average age, 68.2 years; male 72.7%). Eight patients (72.7%) were treatment naive, 9.1% (n = 1) had prior RFA and 18.2% (n = 2) had prior endoscopic mucosal resection. Two patients were excluded from the study. Nine patients (100%) had macroscopic remission and 88.9% (n = 8) had macroscopic remission and microscopic CRIM at 24 months after hybrid-APC ablation. No treatment-related stricture or other major complications were observed, 1 patient (11.1%) reported minor adverse effects. Conclusion : : In this prospective pilot study, hybrid-APC appears safe, feasible and effective after 24 months, which has not been evaluated so far. Further large, multi-centre trials are warranted to confirm the present results.

Abstract

OBJECTIVES To evaluate neurodevelopmental and mental disorders after PICU hospitalization in children requiring invasive mechanical ventilation for severe respiratory illness. DESIGN Retrospective longitudinal observational cohort. SETTING Texas Medicaid Analytic eXtract data from 1999 to 2012. PATIENTS Texas Medicaid-enrolled children greater than or equal to 28 days old to less than 18 years old hospitalized for a primary respiratory illness, without major chronic conditions predictive of abnormal neurodevelopment. INTERVENTIONS We examined rates of International Classification of Diseases, 9th revision-coded mental disorder diagnoses and psychotropic medication use following discharge among children requiring invasive mechanical ventilation for severe respiratory illness, compared with general hospital patients propensity score matched on sociodemographic and clinical characteristics prior to admission. Children admitted to the PICU for respiratory illness not necessitating invasive mechanical ventilation were also compared with matched general hospital patients as a negative control exposure. MEASUREMENTS AND MAIN RESULTS Of 115,335 eligible children, 1,351 required invasive mechanical ventilation and were matched to 6,755 general hospital patients. Compared with general hospital patients, children requiring invasive mechanical ventilation had increased mental disorder diagnoses (hazard ratio, 1.43 [95% CI, 1.26-1.64]; p < 0.0001) and psychotropic medication use (hazard ratio, 1.67 [1.34-2.08]; p < 0.0001) following discharge. Seven-thousand seven-hundred eighty children admitted to the PICU without invasive mechanical ventilation were matched to 38,900 general hospital patients and had increased mental disorder diagnoses (hazard ratio, 1.08 [1.02-1.15]; p = 0.01) and psychotropic medication use (hazard ratio, 1.11 [1.00-1.22]; p = 0.049). CONCLUSIONS Children without major comorbidity requiring invasive mechanical ventilation for severe respiratory illness had a 43% higher incidence of subsequent mental disorder diagnoses and a 67% higher incidence of psychotropic medication use. Both increases were substantially higher than in PICU patients with respiratory illness not necessitating invasive mechanical ventilation. Invasive mechanical ventilation is a life-saving therapy, and its application is interwoven with underlying health, illness severity, and PICU management decisions. Further research is required to determine which factors related to invasive mechanical ventilation and severe respiratory illness are associated with abnormal neurodevelopment. Given the increased risk in these children, identification of strategies for prevention, neurodevelopmental surveillance, and intervention after discharge may be warranted.

Abstract

BACKGROUND & AIMS: Benign biliary strictures (BBS) are complications of chronic pancreatitis (CP). Endotherapy using multiple plastic stents (MPS) or a fully covered self-expanding metal stent (FCSEMS) are acceptable treatment options for biliary obstructive symptoms in these patients. METHODS: Patients with symptomatic CP-associated BBS enrolled in a multicenter randomized noninferiority trial comparing 12-month treatment with MPS vs FCSEMS. Primary outcome was stricture resolution status at 24 months, defined as absence of restenting and 24-month serum alkaline phosphatase not exceeding twice the level at stenting completion. Secondary outcomes included crossover rate, numbers of endoscopic retrograde cholangiopancreatography (ERCPs) and stents, and stent- or procedure-related serious adverse events. RESULTS: Eighty-four patients were randomized to MPS and 80 to FCSEMS. Baseline technical success was 97.6% for MPS and 98.6% for FCSEMS. Eleven patients crossed over from MPS to FCSEMS, and 10 from FCSEMS to MPS. For MPS vs FCSEMS, respectively, stricture resolution status at 24 months was 77.1% (54/70) vs 75.8% (47/62) (P = .008 for noninferiority intention-to-treat analysis), mean number of ERCPs was 3.9 ± 1.3 vs 2.6 ± 1.3 (P < .001, intention-to-treat), and mean number of stents placed was 7.0 ± 4.4 vs 1.3 ± .6 (P < .001, as-treated). Serious adverse events occurred in 16 (19.0%) MPS and 19 (23.8%) FCSEMS patients (P = .568), including cholangitis/fever/jaundice (9 vs 7 patients respectively), abdominal pain (5 vs 5), cholecystitis (1 vs 3) and post-ERCP pancreatitis (0 vs 2). No stent- or procedure-related deaths occurred. CONCLUSIONS: Endotherapy of CP-associated BBS has similar efficacy and safety for 12-month treatment using MPS compared with a single FCSEMS, with FCSEMS requiring fewer ERCPs over 2 years.
