Interest of the POSPOM score in estimating postoperative complication risk after radical cystectomy.

Introduction: Identifying patients at risk after cystectomy for cancer is essential. The POSPOM score is a non-specific urological surgery score for estimating postoperative hospital mortality. This study sought to validate the POSPOM score for predicting postoperative morbidity and mortality after cystectomy.

Pancreatic Allograft Thrombosis: Implementation of the CPAT-Grading System in a Retrospective Series of Simultaneous Pancreas-Kidney Transplantation.

Pancreatic graft thrombosis (PAT) is a major surgical complication, potentially leading to graft loss. The recently proposed Cambridge Pancreas Allograft Thrombosis (CPAT) grading system provides diagnostic, prognostic and therapeutic recommendations. The aim of the present study was to retrospectively assess computed tomography angiography (CTA) examinations performed routinely in simultaneous pancreas-kidney (SPK) recipients to implement the CPAT grading system and to study its association with the recipients' outcomes.

Focused low-intensity pulsed ultrasound alleviates osteoarthritis via restoring impaired FUNDC1-mediated mitophagy.

Mitophagy is critical for maintaining proper cellular functions, and it contributes to the onset and progression of osteoarthritis (OA). A recent study showed that focused low-intensity pulsed ultrasound (FLIPUS) could activate mitophagy, but the molecular mechanism remains unclear. This study aimed to elucidate the chondroprotective effects of FLIPUS in OA and the regulatory effects on FUN14-domain containing 1 (FUNDC1-mediated mitophagy.

Facilitation of axonal transcriptome analysis with quantitative microfluidic devices.

Microfluidic chambers are powerful tools for studying axonal mRNA localization and translation in neurons. In addition to specific manipulation and measurements of axons, microfluidic chambers are used for collecting axonal materials to perform axonal transcriptome analysis. However, traditional bipartite and tripartite chambers have limitations either in purity or quantity of collected axons.

A nomogram based on platelet-to-lymphocyte ratio for predicting pathological complete response of breast cancer after neoadjuvant chemotherapy.

Objective: To investigate the role of platelet-to-lymphocyte ratio (PLR) in complete pathological response (pCR) of breast cancer (BC) patients after neoadjuvant chemotherapy (NAC), as well as to establish and validate a nomogram for predicting pCR.

Methods: BC patients diagnosed and treated in the First Affiliated Hospital of Xi'an Jiaotong University from January 2019 to June 2022 were included. The correlation between pCR and clinicopathological characteristics was analyzed by Chi-square test.

Fabrication of Porous Tantalum with Low Elastic Modulus and Tunable Pore Size for Bone Repair.

Porous tantalum (Ta) is a potential bone substitute due to its excellent biocompatibility and desirable mechanical properties. In this work, a series of porous Ta materials with interconnected micropores and varying pore sizes from 23 to 210 μm were fabricated using spark plasma sintering. The porous structure was formed by thermal decomposition of ammonium bicarbonate powder premixed in the Ta powder.

Knockdown of RSPH14 inhibits proliferation, migration, and invasion and promotes apoptosis of hepatocellular carcinoma via RelA.

Background: High RSPH14 expression appears to be related to poor prognosis of hepatocellular carcinoma (HCC). This study aimed to investigate the possible roles of RSPH14 in the proliferation, apoptosis, and invasion of HCC cells.

Methods: The UALCAN database and Kaplan-Meier Plotter were used to evaluate the expression level and prognostic role of RSPH14 in HCC.

The Synergy of Topographical Micropatterning and Ta|TaCu Bilayered Thin Film on Titanium Implants Enables Dual-Functions of Enhanced Osteogenesis and Anti-Infection.

Poor osteogenesis and implant-associated infection are the two leading causes of failure for dental and orthopedic implants. Surface design with enhanced osteogenesis often fails in antibacterial activity, or vice versa. Herein, a surface design strategy, which overcomes this trade-off via the synergistic effects of topographical micropatterning and a bilayered nanostructured metallic thin film is presented.

Engineering High-Resolution Micropatterns Directly onto Titanium with Optimized Contact Guidance to Promote Osteogenic Differentiation and Bone Regeneration.

Topographical cues play an important role in directing cell behavior, and thus, extensive research efforts have been devoted to fabrication of surface patterns and exploring the contact guidance effect. However, engineering high-resolution micropatterns directly onto metallic implants remains a grand challenge. Moreover, there still lacks evidence that allows translation of in vitro screening to in vivo tissue response.

Cancellous-Bone-like Porous Iron Scaffold Coated with Strontium Incorporated Octacalcium Phosphate Nanowhiskers for Bone Regeneration.

The repair of large bone defects poses a grand challenge in tissue engineering. Thus, developing biocompatible scaffolds with mechanical and structural similarity to human cancellous bone is in great demand. Herein, we fabricated a three-dimensional (3D) porous iron (Fe) scaffold with interconnected pores via a template-assisted electrodeposition method.

Effectiveness and Complications of the AMS AdVance™ Male Sling System for the Treatment of Stress Urinary Incontinence: A Prospective Multicenter Study.

Objective: To evaluate the effectiveness and tolerance of the AdVance Male Sling System for the treatment of male stress urinary incontinence in patients after prostatic surgery.

Methods: An international, observational, prospective, multicenter study was conducted on male patients with urinary incontinence after prostatic surgery. Patients underwent a 24-hour pad test with a threshold at 250 g.

Implementing Cognitive Training Into a Surgical Skill Course: A Pilot Study on Laparoscopic Suturing and Knot Tying.

Mini-invasive surgery-for example, laparoscopy-has challenged surgeons' skills by extending their usual haptic space and displaying indirect visual feedback through a screen. This may require new mental abilities, including spatial orientation and mental representation. This study aimed to test the effect of cognitive training based on motor imagery (MI) and action observation (AO) on surgical skills.

Visible-light-controllable drug release from multilayer-coated microneedles.

A method for the generation of visible-light-controllable drug release polyelectrolyte multilayers on poly(l-lactide) (PLLA) microneedles is developed by host-guest chemistry. In response to visible light irradiation, model drugs encapsulated on polyelectrolyte multilayers transfer into the skin following brief microneedle application.

Clinical-psychological characteristics of refractory globus patients in China.

Background: Refractory globus is not rare in clinical practice, but little research about it.

Aims: To investigate the clinical-psychological characteristics of patients with refractory globus.

Methods: Six hundred and nineteen globus patients were divided into the refractory globus group (n=149) and the non-refractory globus group (n=470).

Distribution profiles of transient receptor potential melastatin- and vanilloid-related channels in rat spermatogenic cells and sperm.

In the present study, we aimed to investigate the expression and distribution of transient receptor potential melastatin (TRPM)- and vanilloid (TRPV)- related channels in rat spermatogenic cells and spermatozoa. Spermatogenic cells and spermatozoa were obtained from male Sprague-Dawley rats. Reverse transcription polymerase chain reaction (RT-PCR) were used to detect the expression of all TRPM and TRPV channel members with specific primers.
