Zero-Strain Sodium Nickel Ferrocyanide as Cathode Material for Sodium-Ion Batteries with Ultra-Long Lifespan.

Prussian blue analogues are recognized as one of the most promising cathode materials for sodium-ion batteries (SIBs) owing to the open 3D framework structure with large interstitial sites and developed Na-ion diffusion channels. However, high content of anion vacancy and poor structural stability have hampered the prospect of their application. In this work, sodium nickel ferrocyanide (NaNi[Fe(CN)], NNHCF) is proposed as cathode material for SIBs.

Integrated bioinformatics analysis and experimental validation to understand tryptophan metabolism-related genes in hepatocellular carcinoma.

Tryptophan (Trp) metabolism is closely related to tumor immunity, and its disorder can cause an immunosuppressive microenvironment, promoting the occurrence and development of hepatocellular carcinoma (HCC). The aim of this study is to explore and validate the independent prognostic genes in patients suffered from HCC. The transcriptome data of GSE87630 from GEO database were downloaded to analyze differentially expressed genes (DECs) which were intersected with the gene sets of Trp metabolism from MsigDB database.

Ultra-stable dendrite-free Na and Li metal anodes enabled by tin selenide host material.

Lithium/sodium metal anodes are considered promising candidates to realize high-energy-density batteries because of their high theoretical specific capacity and low potential. However, their cycling stability are hindered by uncontrolled dendrites growth. Herein, SnSe nanoparticles are tightly anchored on the fiber of carbon cloth (CC) to construct SnSe@CC host material in order to control Li/Na nucleation behavior and restrain dendrites growth.

Single-port robotic-assisted ureteral reconstruction for management of strictures after renal transplantation.

Ureteral strictures are a common and often challenging complication of renal transplantation. The use of single-port (SP) robotic-assisted laparoscopic surgery is a novel approach in the management of these patients. Here we describe 3 patients with stricture of the transplant ureter causing hydronephrosis and allograft dysfunction, whose ureteral reconstructions were successfully performed using the SP robotic-assisted laparoscopic approach.

3D Reconstruction of Carotid Artery from Ultrasound Images.

3D reconstruction is an important area in computer vision, which can be applied to assist in medical diagnosis. Compared to observing 2D ultrasound images, 3D models are more suitable for diagnostic interpretation. In this paper, we describe an approach for 3D reconstruction of the carotid artery utilizing ultrasound images from the transverse and longitudinal views.

Graphene/Silver Nanowires/Graphene Sandwich Composite for Stretchable Transparent Electrodes and Its Fracture Mechanism.

Polycrystalline graphene grown by chemical vapor deposition (CVD) is characterized by line defects and disruptions at the grain boundaries and nucleation sites. This adversely affects the stretchability and conductivity of graphene, which limits its applications in the field of flexible, stretchable, and transparent electrodes. We demonstrate a composite electrode comprised of a graphene/silver nanowires (AgNWs)/graphene sandwich structure on a polydimethylsiloxane substrate to overcome this limitation.

Contemporary National Trends and Variations of Pelvic Lymph Node Dissection in Patients Undergoing Robot-Assisted Radical Prostatectomy.

Introduction: Previous studies showed suboptimal adherence to clinical practice guidelines for pelvic lymph node dissection (PLND) during radical prostatectomy (RP). Robot-assisted RP (RARP) has become the predominant surgical management for localized prostate cancer in the United States but contemporary national data on PLND adherence during RARP are still lacking.

Methods: RARPs for clinically localized (cT1-2N0M0) intermediate-risk and high-risk prostate cancer diagnosed between 2010 and 2016 in National Cancer Database were identified.

Second opinion pathologic review in the management of prostate cancer.

Unlabelled: INTRODUCTION Inter-institutional re-review of prostate needle biopsy (PNBx) material is required at many institutions before definitive treatment, but adds time and cost and may not significantly alter urologic management. We aim to determine the utility of universal PNBx re-review on influencing the decision to recommend definitive local therapy for patients with prostate cancer.

Materials And Methods: From 2017-2020, 590 prostate biopsy specimens from outside institutions were re-reviewed at our center for patients considering prostatectomy.

Extended Experience with a Dynamic, Data-Driven Selective Drain Management Protocol in Pancreaticoduodenectomy: Progressive Risk Stratification for Better Practice.

Background: Intraoperative drain use for pancreaticoduodenectomy has been practiced in an unconditional, binary manner (placement/no placement). Alternatively, dynamic drain management has been introduced, incorporating the Fistula Risk Score (FRS) and drain fluid amylase (DFA) analysis, to mitigate clinically relevant postoperative pancreatic fistula (CR-POPF).

Study Design: An extended experience with dynamic drain management was used at a single institution for 400 consecutive pancreaticoduodenectomies (2014 to 2019).

Long-term Functional, Psychological, Emotional, and Social Outcomes in Survivors of Firearm Injuries.

Importance: The outcomes of firearm injuries in the United States are devastating. Although firearm mortality and costs have been investigated, the long-term outcomes after surviving a gunshot wound (GSW) remain unstudied.

Objective: To determine the long-term functional, psychological, emotional, and social outcomes among survivors of firearm injuries.

Defining the Safety Profile for Performing Pancreatoduodenectomy in the Setting of Hyperbilirubinemia.

Background: Hyperbilirubinemia is commonly observed in patients requiring pancreatoduodenectomy (PD). Thus far, literature regarding the danger of operating in the setting of hyperbilirubinemia is equivocal. What remains undefined is at what specific level of bilirubin there is an adverse safety profile for undergoing PD.

Decoding Grade B Pancreatic Fistula: A Clinical and Economical Analysis and Subclassification Proposal.

Objective: The aim of this study was to describe characteristics and management approaches for grade B pancreatic fistula (B-POPF) and investigate whether it segregates into distinct subclasses.

Background: The 2016 ISGPS refined definition of B-POPF is predicated on various postoperative management approaches, ranging from prolonged drainage to interventional procedures, but the spectrum of clinical severity within this entity is yet undefined.

Methods: Pancreatectomies performed at 2 institutions from 2007 to 2016 were reviewed to identify B-POPFs and their treatment strategies.

Identification of an Optimal Cut-off for Drain Fluid Amylase on Postoperative Day 1 for Predicting Clinically Relevant Fistula After Distal Pancreatectomy: A Multi-institutional Analysis and External Validation.

Objective: The aim of this study was to investigate the relationship between drain fluid amylase value on the first postoperative day (DFA1) and clinically relevant fistula (CR-POPF) after distal pancreatectomy (DP), and to identify the cut-off of DFA1 that optimizes CR-POPF prediction.

Background: DFA1 is a well-recognized predictor of CR-POPF after pancreatoduodenectomy, but its role in DP is largely unexplored.

Methods: DFA1 levels were correlated with CR-POPF in 2 independent multi-institutional sets of DP patients: developmental (n = 338; years 2012 to 2017) and validation cohort (n = 166; years 2006 to 2016).
