Sequencing by avidity enables high accuracy with low reagent consumption.

We present avidity sequencing, a sequencing chemistry that separately optimizes the processes of stepping along a DNA template and that of identifying each nucleotide within the template. Nucleotide identification uses multivalent nucleotide ligands on dye-labeled cores to form polymerase-polymer-nucleotide complexes bound to clonal copies of DNA targets. These polymer-nucleotide substrates, termed avidites, decrease the required concentration of reporting nucleotides from micromolar to nanomolar and yield negligible dissociation rates. Avidity sequencing achieves high accuracy, with 96.2% and 85.4% of base calls having an average of one error per 1,000 and 10,000 base pairs, respectively. We show that the average error rate of avidity sequencing remained stable following a long homopolymer.

Selective internal radiation therapy with yttrium-90 resin microspheres followed by anatomical hepatectomy: A potential curative strategy in advanced hepatocellular carcinoma.

About 80% of hepatocellular carcinoma (HCC) patients are in advanced stages and ineligible for curative surgery. Palliative treatments just maintained limited survival, thus an effective downstaging therapy is badly needed. Here we report an initially unresectable patient who underwent radical hepatectomy after successful downstaging with selective internal radiation therapy (SIRT). A 34-year-old man was diagnosed with China Liver Cancer Staging (CNLC) IIIa HCC. Due to insufficient future liver remnant and vascular involvement, the patient was suggested to be unresectable. SIRT with yttrium-90 resin microspheres was given. At three months post-SIRT, a complete response was achieved. The tumor was downstaged to CNLC Ia stage. The patient underwent anatomical hepatectomy 5 months after SIRT. Histopathological examination of the resected specimen showed 4% viable tumor cells inside a necrotic mass. To our knowledge, this is the first case who underwent SIRT with yttrium-90 resin microspheres in China mainland. The success of the downstaging in this case renders a possible cure to be achieved in an initially unresectable patient. In addition, the nearly complete tumor necrosis in the resected specimen indicates a good prognosis post-surgery. This is the first case who underwent SIRT with yttrium-90 resin microspheres in China mainland. SIRT followed by anatomical hepatectomy is a potentially curative strategy for unresectable HCC, which deserves a confirmative trial in the future.

Implantation of a toric intraocular lens after repeated radial keratotomy procedures: A case report.

Corneal alterations due to radial keratotomy (RK) complicate intraocular lens calculations, which may explain why there have been few reports of toric intraocular lens (TIOL) implantation after excessive or multiple operations. A 71-year-old male with a history of repeated RKs and at least 30 corneal incisions in each eye was referred for cataract surgery. Preoperatively, the best-corrected distance visual acuity was 0.7 decimal (0.15 logMAR) in the right eye and 0.9 decimal (0.05 logMAR) in the left eye. The refractive errors were -8.00 -3.00 × 80 and -6.00 -3.50 × 80, respectively. The total corneal cylindrical powers (real power; anterior and posterior) were, respectively, -0.90 D and -3.60 D at 9 a.m., compared to -1.60 D and -3.80 D at 1 p.m. Corneal astigmatism in the left eye was considered symmetric and diurnally stable; therefore, an XY1AT6 TIOL (Hoya, Tokyo, Japan; cylindrical power at the plane, +3.75 D) was implanted. A non-toric intraocular lens, the XY1 (Hoya), was implanted in the right eye. Six-month postoperative best-corrected distance visual acuities were 1.2 decimal (-0.08 logMAR) and 1.0 decimal (0.00 logMAR) in the right and left eyes, respectively. Post-operative manifest refractions were +0.00 -3.00 × 70 and -1.00 -2.00 × 85, respectively. The TIOL reduced refractive astigmatism in the left eye; therefore, we believe that even after multiple RKs, the TIOL can be a suitable candidate to correct astigmatism if the corneal astigmatism is diurnally stable and symmetric.

NULISA: a proteomic liquid biopsy platform with attomolar sensitivity and high multiplexing.

The blood proteome holds great promise for precision medicine but poses substantial challenges due to the low abundance of most plasma proteins and the vast dynamic range of the plasma proteome. Here we address these challenges with NUcleic acid Linked Immuno-Sandwich Assay (NULISA™), which improves the sensitivity of traditional proximity ligation assays by ~10,000-fold to attomolar level, by suppressing assay background via a dual capture and release mechanism built into oligonucleotide-conjugated antibodies. Highly multiplexed quantification of both low- and high-abundance proteins spanning a wide dynamic range is achieved by attenuating signals from abundant targets with unconjugated antibodies and next-generation sequencing of barcoded reporter DNA. A 200-plex NULISA containing 124 cytokines and chemokines and other proteins demonstrates superior sensitivity to a proximity extension assay in detecting biologically important low-abundance biomarkers in patients with autoimmune diseases and COVID-19. Fully automated NULISA makes broad and in-depth proteomic analysis easily accessible for research and diagnostic applications.

Diagnosis of Alzheimer's disease via resting-state EEG: integration of spectrum, complexity, and synchronization signal features.

Background: Alzheimer's disease (AD) is the most common neurogenerative disorder, making up 70% of total dementia cases with a prevalence of more than 55 million people. Electroencephalogram (EEG) has become a suitable, accurate, and highly sensitive biomarker for the identification and diagnosis of AD. Methods: In this study, a public database of EEG resting state-closed eye recordings containing 36 AD subjects and 29 normal subjects was used. And then, three types of signal features of resting-state EEG, i.e., spectrum, complexity, and synchronization, were performed by applying various signal processing and statistical methods, to obtain a total of 18 features for each signal epoch. Next, the supervised machine learning classification algorithms of decision trees, random forests, and support vector machine (SVM) were compared in categorizing processed EEG signal features of AD and normal cases with leave-one-person-out cross-validation. Results: The results showed that compared to normal cases, the major change in EEG characteristics in AD cases was an EEG slowing, a reduced complexity, and a decrease in synchrony. The proposed methodology achieved a relatively high classification accuracy of 95.65, 95.86, and 88.54% between AD and normal cases for decision trees, random forests, and SVM, respectively, showing that the integration of spectrum, complexity, and synchronization features for EEG signals can enhance the performance of identifying AD and normal subjects. Conclusion: This study recommended the integration of EEG features of spectrum, complexity, and synchronization for aiding the diagnosis of AD.

NULISA: a novel proteomic liquid biopsy platform with attomolar sensitivity and high multiplexing.

The blood proteome holds great promise for precision medicine but poses substantial challenges due to the low abundance of most plasma proteins and the vast dynamic range across the proteome. We report a novel proteomic technology - NUcleic acid Linked Immuno-Sandwich Assay (NULISA™) - that incorporates a dual capture and release mechanism to suppress the assay background and improves the sensitivity of the proximity ligation assay by over 10,000-fold to the attomolar level. It utilizes pairs of antibodies conjugated to DNA oligonucleotides that enable immunocomplex purification and generate reporter DNA containing target- and sample-specific barcodes for a next-generation sequencing-based, highly multiplexed readout. A 200-plex NULISA targeting 124 cytokines and chemokines and 80 other immune response-related proteins demonstrated superior sensitivity for detecting low-abundance proteins and high concordance with other immunoassays. The ultrahigh sensitivity allowed the detection of previously difficult-to-detect, but biologically important, low-abundance biomarkers in patients with autoimmune diseases and COVID-19. Fully automated NULISA addresses longstanding challenges in proteomic analysis of liquid biopsies and makes broad and in-depth proteomic analysis accessible to the general research community and future diagnostic applications.

Development of an Electronic Medical Tool to Facilitate Allocation of Limited Resources in Times of Crisis.

The COVID-19 pandemic has made decisions about resource allocation and reallocation real possibilities even in high-resource settings. In April 2020, in preparation for such an eventuality, Atlantic Health System began to develop a real-time instrument built into the EMR to assist with such decisions. The instrument calculated the modified Sequential Organ Failure Assessment for all patients admitted, in real time, to assist triage teams make decisions if crisis standards of care were declared. A pilot assessment of the instrument was performed using retrospective data by nine members of the triage teams, who were asked to identify the six patients at highest risk of reallocation. Agreement about which patients were at highest risk of resource reallocation was good, but not perfect. All raters agreed on five of the six patients, but only seven of nine agreed on the final patient. Among the six consensus selections for reallocation, five died prior to hospital discharge. All patients at highest risk of reallocation had a predicted life expectancy of less than 1 year. In conclusion, the instrument was easy to use, and the concordance among raters was good but not perfect. Predicted life expectance was a major determinant of the triage score.

Utility of Transjugular Intrahepatic Portosystemic Shunt Placement for Maintaining Portal Vein Patency in Candidates on Wait Lists Who Develop Thrombus.

OBJECTIVES: Although no longer a contraindication to liver transplant, portal vein thrombosis may lead to longer operative time and complexities in venous reconstruction. Strategies to maintain preoperative patency include systemic anticoagulation and/or transjugular intrahepatic portosystemic shunt placement. The former may not be ideal in cirrhotic patients prone to luminal gastrointestinal tract bleeding, and factors that predict improvements in portal vein thrombosis with the latter have not been well defined. Our goal was to evaluate the effectiveness of transjugular intrahepatic portosystemic shunt placement as monotherapy to improve and/or resolve portal vein thrombosis in otherwise eligible liver transplant candidates with partial or complete portal vein thrombosis and to identify factors predicting success. MATERIALS AND METHODS: We identified 30 patients from 2010 to 2015 who had transjugular intrahepatic portosystemic shunt placementfor primary indication to maintain portal vein patency. RESULTS: The main portal vein was completely thrombosed in 5 of 30 (16.6%), nearly completely thrombosed in 9 of 30 (30%), and partially thrombosed in 16 patients (53.3%). Twenty-four patients (80%) had improvement and/or resolution of portal vein thrombosis after transjugular intrahepatic portosystemic shunt placement, with 18 of these (75%) having complete resolution. All 5 patients (20.8%) with complete thrombosis had improvement/resolution of portal vein thrombosis. Nine patients (30%) required hospitalization within 3 months for hepatic encephalopathy. There were 3 deaths (10%) not related to transjugular intrahepatic portosystemic shunt placement (10%). Nine patients underwent liver transplant after shunt placement (median 2.9 mo; range, 0.3-32 mo); all 9 received endto-end anastomosis without need for intraoperative thrombectomy. CONCLUSIONS: Transjugular intrahepatic portosystemic shunt placement may be effective as monotherapy for maintaining or restoring portal vein patency in selected livertransplant candidates, even in those with complete portal vein thrombosis. Further studies are needed to define potential responders to this approach.

Race and Gradient Difference Are Associated with Increased Risk of Hepatic Encephalopathy Hospital Admission After Transjugular Intrahepatic Portosystemic Shunt Placement.

BACKGROUND/AIMS: Hepatic encephalopathy (HE) is a well-recognized complication of transjugular intrahepatic portosystemic shunt (TIPS) placement. The aim of this investigation was to evaluate incidence and predictors of post-TIPS HE necessitating hospital admission in a non-clinical trial setting. METHODS: We performed a retrospective cohort study identifying 273 consecutive patients undergoing TIPS from 2010 to 2015 for any indication; 210 met inclusion/exclusion criteria. The primary endpoint was incidence of post-TIPS HE defined as encephalopathy with no other identifiable cause requiring hospitalization within 90 days of TIPS. Clinical demographics and procedural variables were collected and analyzed to determine predictors of readmission for post-TIPS HE. Categorical variables were analyzed using Fisher's exact test; continuous variables were compared using Levene's t-test and student's t-test; P < 0.05, significant. RESULTS: Forty-two of 210 patients (20%) developed post-TIPS HE requiring hospitalization within 90 days. On analysis of cohorts (post-TIPS HE vs. no post-TIPS HE): non-white race (31.0% vs. 17.5%, P = 0.022) and increased hepatic venous pressure gradient (HVPG) difference during TIPS (10.5 vs. 8.9 mmHg, P = 0.030) were associated with an increased incidence of HE requiring readmission within 90 days. CONCLUSIONS: HE remains a common complication of TIPS. Non-Caucasian race is a significant clinical demographic associated with increased risk for readmission. Independent of initial or final HVPG, HVPG difference appears to be a significant modifiable technical risk factor. In the absence of clear preventative strategies for post-TIPS encephalopathy, non-Caucasians with HVPG reductions >9 mmHg may require targeted follow up evaluation to prevent hospital readmission.

Refractory Hepatic Encephalopathy After Elective Transjugular Intrahepatic Portosystemic Shunt: Risk Factors and Outcomes with Revision.

BACKGROUND AND AIMS: Hepatic encephalopathy (HE) is a common complication of elective transjugular intrahepatic portosystemic shunt (TIPS) placement and is often successfully medically managed. Risk factors for refractory hepatic encephalopathy (RHE) necessitating revision of TIPS are not well defined. We evaluated the incidence, predictors, and outcomes of post-TIPS RHE necessitating TIPS revision. METHODS: In a retrospective cohort study of 174 consecutive patients undergoing elective TIPS placement (2010-2015), we evaluated the incidence of post-TIPS RHE. Clinical demographics and procedural variables were collected. 1-year outcomes after revision were collected. RESULTS: Ten of 174 patients (5.7%) developed post-TIPS RHE requiring revision. Significant differences between RHE and non-refractory groups were shunt size > 8 versus ≤ 8 mm (18.5 vs. 3.4%, p = 0.001), history of HE (14 vs. 2%, p = 0.007), and serum albumin levels ≤ 2.5 versus > 2.5 g/dL (13.1 vs. 3.1%, p = 0.020). On multivariate analysis, shunt size > 8 mm (p = 0.001), history of HE prior to TIPS (p = 0.006), and low serum albumin (≤ 2.5 g/dL) (p = 0.022) remained independent predictors of RHE, controlling for age and Model for End-Stage Liver Disease score. RHE improved in 8 of 10 patients but survival at 1 year without liver transplantation (LT) was only 10%. CONCLUSION: While TIPS revision successfully improves RHE in most cases, 1-year mortality rates are high, limiting the value of revision in non-LT candidates. Patients with previous history of HE and low serum albumin levels prior to TIPS may benefit most from the use of shunt sizes < 8 mm to mitigate the risk of RHE. LEVEL OF EVIDENCE: Level 4, case series.

Hepatitis C Virus Subverts Human Choline Kinase-α To Bridge Phosphatidylinositol-4-Kinase IIIα (PI4KIIIα) and NS5A and Upregulates PI4KIIIα Activation, Thereby Promoting the Translocation of the Ternary Complex to the Endoplasmic Reticulum for Viral Replication.

In this study, we elucidated the mechanism by which human choline kinase-α (hCKα) interacts with nonstructural protein 5A (NS5A) and phosphatidylinositol-4-kinase IIIα (PI4KIIIα), the lipid kinase crucial for maintaining the integrity of virus-induced membranous webs, and modulates hepatitis C virus (HCV) replication. hCKα activity positively modulated phosphatidylinositol-4-phosphate (PI4P) levels in HCV-expressing cells, and hCKα-mediated PI4P accumulation was abolished by AL-9, a PI4KIIIα-specific inhibitor. hCKα colocalized with NS5A and PI4KIIIα or PI4P; NS5A expression increased hCKα and PI4KIIIα colocalization; and hCKα formed a ternary complex with PI4KIIIα and NS5A, supporting the functional interplay of hCKα with PI4KIIIα and NS5A. PI4KIIIα inactivation by AL-9 or hCKα inactivation by CK37, a specific hCKα inhibitor, impaired the endoplasmic reticulum (ER) localization and colocalization of these three molecules. Interestingly, hCKα knockdown or inactivation inhibited PI4KIIIα-NS5A binding. In an in vitro PI4KIIIα activity assay, hCKα activity slightly increased PI4KIIIα basal activity but greatly augmented NS5A-induced PI4KIIIα activity, supporting the essential role of ternary complex formation in robust PI4KIIIα activation. Concurring with the upregulation of PI4P production and viral replication, overexpression of active hCKα-R (but not the D288A mutant) restored PI4KIIIα and NS5A translocation to the ER in hCKα stable knockdown cells. Furthermore, active PI4KIIIα overexpression restored PI4P production, PI4KIIIα and NS5A translocation to the ER, and viral replication in CK37-treated cells. Based on our results, hCKα functions as an indispensable regulator that bridges PI4KIIIα and NS5A and potentiates NS5A-stimulated PI4KIIIα activity, which then facilitates the targeting of the ternary complex to the ER for viral replication.IMPORTANCE The mechanisms by which hCKα activity modulates the transport of the hCKα-NS5A complex to the ER are not understood. In the present study, we investigated how hCKα interacts with PI4KIIIα (a key element that maintains the integrity of the "membranous web" structure) and NS5A to regulate viral replication. We demonstrated that HCV hijacks hCKα to bridge PI4KIIIα and NS5A, forming a ternary complex, which then stimulates PI4KIIIα activity to produce PI4P. Pronounced PI4P synthesis then redirects the translocation of the ternary complex to the ER-derived, PI4P-enriched membrane for assembly of the viral replication complex and viral replication. Our study provides novel insights into the indispensable modulatory role of hCKα in the recruitment of PI4KIIIα to NS5A and in NS5A-stimulated PI4P production and reveals a new perspective for understanding the impact of profound PI4KIIIα activation on the targeting of PI4KIIIα and NS5A to the PI4P-enriched membrane for viral replication complex formation.

Military Medicine Interest Groups in U.S. Medical Schools.

Medical student interest groups are organizations that help expose students to different medical specialties and fields of medicine while in medical school. Military medicine interest groups (MMIGs) are a particular type of interest group that spreads information about military medicine, fosters mentorship, and camaraderie between students and military faculty, and increases the opportunities for leadership while in medical school. Surveys were sent to all U.S. medical schools to determine how many schools had an MMIG. If a medical school had a group, a second survey was sent to the student leader to determine more information about how their group operated (such as type of participants, funding sources, activities, faculty involvement, military health care provider involvement, etc.). Fifty-six percent of U.S. medical schools who responded were found to have an MMIG and most participants were students in the Health Professions Scholarship Program. Information about military medicine was found to be the biggest impact of having a group at a medical school and student leaders expressed they wished to have more military health care provider involvement. The results of this study could help start MMIGs at other medical schools, as well as give ideas to current MMIGs on how other groups operate.

Human Choline Kinase-α Promotes Hepatitis C Virus RNA Replication through Modulation of Membranous Viral Replication Complex Formation.

UNLABELLED: Hepatitis C virus (HCV) infection reorganizes cellular membranes to create an active viral replication site named the membranous web (MW). The role that human choline kinase-α (hCKα) plays in HCV replication remains elusive. Here, we first showed that hCKα activity, not the CDP-choline pathway, promoted viral RNA replication. Confocal microscopy and subcellular fractionation of HCV-infected cells revealed that a small fraction of hCKα colocalized with the viral replication complex (RC) on the endoplasmic reticulum (ER) and that HCV infection increased hCKα localization to the ER. In the pTM-NS3-NS5B model, NS3-NS5B expression increased the localization of the wild-type, not the inactive D288A mutant, hCKα on the ER, and hCKα activity was required for effective trafficking of hCKα and NS5A to the ER. Coimmunoprecipitation showed that hCKα was recruited onto the viral RC presumably through its binding to NS5A domain 1 (D1). hCKα silencing or treatment with CK37, an hCKα activity inhibitor, abolished HCV-induced MW formation. In addition, hCKα depletion hindered NS5A localization on the ER, interfered with NS5A and NS5B colocalization, and mitigated NS5A-NS5B interactions but had no apparent effect on NS5A-NS4B and NS4B-NS5B interactions. Nevertheless, hCKα activity was not essential for the binding of NS5A to hCKα or NS5B. These findings demonstrate that hCKα forms a complex with NS5A and that hCKα activity enhances the targeting of the complex to the ER, where hCKα protein, not activity, mediates NS5A binding to NS5B, thereby promoting functional membranous viral RC assembly and viral RNA replication. IMPORTANCE: HCV infection reorganizes the cellular membrane to create an active viral replication site named the membranous web (MW). Here, we report that human choline kinase-α (hCKα) acts as an essential host factor for HCV RNA replication. A fraction of hCKα colocalizes with the viral replication complex (RC) on the endoplasmic reticulum (ER) in HCV-infected cells. NS3-NS5B expression increases ER localization of wild-type, but not D288A mutant, hCKα, and hCKα activity facilitates the transport of itself and NS5A to the ER. Silencing or inactivation of hCKα abrogates MW formation. Moreover, hCKα is recruited by NS5A independent of hCKα activity, presumably through binding to NS5A D1. hCKα activity then mediates the ER targeting of the hCKα-NS5A complex. On the ER membrane, hCKα protein, per se, induces NS5A binding to NS5B, thereby promoting membranous RC formation and viral RNA replication. Our study may benefit the development of hCKα-targeted anti-HCV therapeutics.

Phosphoproteomics Identified an NS5A Phosphorylation Site Involved in Hepatitis C Virus Replication.

The non-structural protein 5A (NS5A) is a hepatitis C virus (HCV) protein indispensable for the viral life cycle. Many prior papers have pinpointed several serine residues in the low complexity sequence I region of NS5A responsible for NS5A phosphorylation; however, the functions of specific phosphorylation sites remained obscure. Using phosphoproteomics, we identified three phosphorylation sites (serines 222, 235, and 238) in the NS5A low complexity sequence I region. Reporter virus and replicon assays using phosphorylation-ablated alanine mutants of these sites showed that Ser-235 dominated over Ser-222 and Ser-238 in HCV replication. Immunoblotting using an Ser-235 phosphorylation-specific antibody showed a time-dependent increase in Ser-235 phosphorylation that correlated with the viral replication activity. Ser-235 phosphorylated NS5A co-localized with double-stranded RNA, consistent with its role in HCV replication. Mechanistically, Ser-235 phosphorylation probably promotes the replication complex formation via increasing NS5A interaction with the human homologue of the 33-kDa vesicle-associated membrane protein-associated protein. Casein kinase Iα (CKIα) directly phosphorylated Ser-235 in vitro. Inhibition of CKIα reduced Ser-235 phosphorylation and the HCV RNA levels in the infected cells. We concluded that NS5A Ser-235 phosphorylated by CKIα probably promotes HCV replication via increasing NS5A interaction with the 33-kDa vesicle-associated membrane protein-associated protein.

Emerging roles of interferon-stimulated genes in the innate immune response to hepatitis C virus infection.

Infection with hepatitis C virus (HCV), a major viral cause of chronic liver disease, frequently progresses to steatosis and cirrhosis, which can lead to hepatocellular carcinoma. HCV infection strongly induces host responses, such as the activation of the unfolded protein response, autophagy and the innate immune response. Upon HCV infection, the host induces the interferon (IFN)-mediated frontline defense to limit virus replication. Conversely, HCV employs diverse strategies to escape host innate immune surveillance. Type I IFN elicits its antiviral actions by inducing a wide array of IFN-stimulated genes (ISGs). Nevertheless, the mechanisms by which these ISGs participate in IFN-mediated anti-HCV actions remain largely unknown. In this review, we first outline the signaling pathways known to be involved in the production of type I IFN and ISGs and the tactics that HCV uses to subvert innate immunity. Then, we summarize the effector mechanisms of scaffold ISGs known to modulate IFN function in HCV replication. We also highlight the potential functions of emerging ISGs, which were identified from genome-wide siRNA screens, in HCV replication. Finally, we discuss the functions of several cellular determinants critical for regulating host immunity in HCV replication. This review will provide a basis for understanding the complexity and functionality of the pleiotropic IFN system in HCV infection. Elucidation of the specificity and the mode of action of these emerging ISGs will also help to identify novel cellular targets against which effective HCV therapeutics can be developed.

Resolving complex research data management issues in biomedical laboratories: Qualitative study of an industry-academia collaboration.

This paper describes a distributed collaborative effort between industry and academia to systematize data management in an academic biomedical laboratory. Heterogeneous and voluminous nature of research data created in biomedical laboratories make information management difficult and research unproductive. One such collaborative effort was evaluated over a period of four years using data collection methods including ethnographic observations, semi-structured interviews, web-based surveys, progress reports, conference call summaries, and face-to-face group discussions. Data were analyzed using qualitative methods of data analysis to (1) characterize specific problems faced by biomedical researchers with traditional information management practices, (2) identify intervention areas to introduce a new research information management system called Labmatrix, and finally to (3) evaluate and delineate important general collaboration (intervention) characteristics that can optimize outcomes of an implementation process in biomedical laboratories. Results emphasize the importance of end user perseverance, human-centric interoperability evaluation, and demonstration of return on investment of effort and time of laboratory members and industry personnel for success of implementation process. In addition, there is an intrinsic learning component associated with the implementation process of an information management system. Technology transfer experience in a complex environment such as the biomedical laboratory can be eased with use of information systems that support human and cognitive interoperability. Such informatics features can also contribute to successful collaboration and hopefully to scientific productivity.
