Kidney function and bone mineral density in chronic kidney disease patients.

Background: Bone mineral density (BMD) predicts fracture risk in patients with chronic kidney disease (CKD) and in the general population. However, few studies have investigated risk factors for bone loss in patients with CKD. The aim of this study was to investigate whether renal function is associated with the rate of BMD decline.

Successful management of catheter injury or refractory infection by partial replantation of peritoneal dialysis catheters: a retrospective observational study.

Background: The revised 2023 guidelines from the International Society for Peritoneal Dialysis (ISPD) emphasize salvage methods for treating refractory catheter-related infections, or mechanical catheter damage. This approach preserves the existing catheter by manipulating only the outer cuff above the peritoneum, avoiding hemodialysis transfer. We investigated the effectiveness of the partial replantation technique.

Elucidating early proton irradiation effects in metal halide perovskites via photoluminescence spectroscopy.

Metal halide perovskite (MHP) solar cells are promising aerospace power sources given their potential as inexpensive, lightweight, and resilient solar electricity generators. Herein, the intrinsic radiation tolerance of unencapsulated methylammonium lead iodide/chloride (CHNHPbICl) films was isolated. Spatially resolved photoluminescence (PL) spectroscopy and confocal microscopy revealed the fundamental defect physics through optical changes as films were irradiated with 4.

Use of Aspirin and Initial Cardiovascular and Bleeding Risk in Patients with Chronic Kidney Disease.

Key Points: The association between aspirin use and risk of the first cardiovascular event was NS in patients with CKD. Compared with nonusers, aspirin users had an increased risk of significant bleeding events. Aspirin prescription for the primary prevention of cardiovascular disease in patients with CKD needs careful consideration.

Paramedian Unilateral 'Bitubular' Endoscopic Access for a Far Lateral Disc Herniation: A Novel Approach for Far Lateral Lumbar Pathologies.

We present a novel technique to approach far lateral lumbar pathologies using a bitubular, biportal endoscopic system and a paramedian approach. Background: Conventional approaches for lumbar far lateral discectomy range from open approaches to newer minimally invasive approaches such as tubular discectomy and single portal endoscopic discectomy. We present a case of a patient suffering with a left L3-4 and left L4-5 extraforaminal disc herniation who was treated successfully with a left sided bitubular, biportal endoscopic 2 level far lateral discectomy.

Medication Burden and Adverse Cardiovascular Events and Death in Patients Treated with Maintenance Hemodialysis: A Nationwide Cohort Study.

Key Points: A higher medication burden was associated with a higher risk of adverse events in patients receiving maintenance hemodialysis. Medication burden can serve as a clinically relevant risk indicator for cardiovascular events and all-cause death in patients on maintenance hemodialysis.

Background: A high medication burden is associated with adverse outcomes.

Frequent complications of deficient patellae after component removal in 1.5-stage exchange arthroplasty for periprosthetic joint infection.

Purpose: To compare the complication rates between deficient patellae (remnant patellae after component removal) and non-resurfaced patellae after 1.5-stage exchange arthroplasty for periprosthetic joint infection and identify risk factors for complications of deficient patellae.

Methods: Complications in 76 deficient patellae (group D) and 41 non-resurfaced patellae (group N), with a minimum follow-up of 2 years after 1.

Freely suspended nematic and smectic films and free-standing smectic filaments in the ferroelectric nematic realm.

We show that stable, freely suspended liquid crystal films can be made from the ferroelectric nematic (N) phase and from the recently discovered polar, lamellar SmZ and SmA phases. The N films display two-dimensional, smectic-like parabolic focal conic textures comprising director/polarization bend that are a manifestation of the electrostatic suppression of director splay in the film plane. In the SmZ and SmA phases, the smectic layers orient preferentially normal to the film surfaces, a condition never found in typical thermotropic or lyotropic lamellar LC phases, with the SmZ films exhibiting focal-conic fan textures mimicking the appearance of typical smectics in glass cells when the layers are oriented normal to the plates, and the SmA films showing a texture of plaquettes of uniform in-plane orientation where both bend and splay are suppressed, separated by grain boundaries.

Impact of a Unilateral High Tibial Osteotomy With a Large Correction on Functional Lateral Acetabular Coverage of the Hip Joint.

Background: Changes in limb length and coronal pelvic tilt, which occur along with changes in limb alignment, may affect the functional lateral acetabular coverage of the hip joint under weightbearing conditions.

Purpose: To analyze the functional lateral acetabular coverage after unilateral closed-wedge and open-wedge high tibial osteotomies with a large wedge correction of ≥10 mm.

Study Design: Cohort study; Level of evidence, 3.

Resistance of Boron Nitride Nanotubes to Radiation-Induced Oxidation.

We present unprecedented results on the damage thresholds and pathways for boron nitride nanotubes (BNNT) under the influence of energetic electrons in an oxidative gas environment, using an environmental aberration-corrected electron microscope over a range of oxygen pressures. We observe a damage cascade process that resists damage until a higher electron dose, compared with carbon nanotubes, initiating at defect-free BNNT sidewalls and proceeding through the conversion from crystalline nanotubes to amorphous boron nitride (BN), resisting oxidation throughout. We compare with prior results on the oxidation of carbon nanotubes and present a model that attributes the onset of damage in both cases to a physisorbed oxygen layer that reduces the threshold for damage onset.

THOC1 complexes with SIN3A to regulate R-loops and promote glioblastoma progression.

Glioblastoma (GBM), the most common and aggressive malignant brain tumor in adults, has a median survival of 21 months. To identify drivers of GBM proliferation, we conducted a CRISPR-knockout screen, which revealed THO Complex 1 (THOC1) as a key driver. Knocking down THOC1 significantly reduced GBM cell viability across patient-derived xenograft (PDX) lines, enhancing survival (p<0.

Non-Alcoholic Fatty Liver Disease and Its Association with Kidney and Cardiovascular Outcomes in Moderate to Advanced Chronic Kidney Disease.

Introduction: Non-alcoholic fatty liver disease (NAFLD) has emerged as a potential indicator for cardio-metabolic risk. However, clinical implications of NAFLD in patients with chronic kidney disease (CKD) are still elusive. We investigated to explore the association between NAFLD and adverse clinical outcomes among patients with CKD.

Placental growth factor deficiency initiates obesity- and aging-associated metabolic syndrome.

Obesity often leads to inadequate angiogenesis in expanding adipose tissue, resulting in inflammation and insulin resistance. We explored the role of placental growth factor (PlGF) in metabolic syndrome (MS) using mice models of type 2 diabetes, high-fat diet, or aging. Reduced serum PlGF levels were associated with decreased insulin sensitivity and development of MS features.

Biportal endoscopic en bloc removal of the ligamentum flavum for spinal stenosis: nuances for the "butterfly" technique.

The introduction of endoscopic spine surgery has led to a paradigm shift in the treatment of spinal disorders. In particular, biportal endoscopic surgery has gained traction for its wider visual field and improved the maneuverability of instruments, familiar anatomy, and costeffectiveness. In this study, we describe our en bloc removal of the ligamentum flavum using a "butterfly" technique.

Differential inducibility of transmembrane peptidoglycan recognition proteins (PGRPs) by bacterial challenges in the earthworm, Eisenia andrei.

Peptidoglycan recognition proteins (PGRPs) and Toll-like receptors (TLRs) are highly conserved pattern recognition receptors (PRRs). Earthworms possess genes encoding TLRs that specifically respond to Gram-positive bacteria. In addition, several PGRPs have been recently identified, which are predicted to exhibit amidase activity but lack receptor function.

Monolithic DNApatite: An Elastic Apatite with Sub-Nanometer Scale Organo-Inorganic Structures.

Hydroxyapatite (HA) exhibits outstanding biocompatibility, bioactivity, osteoconductivity, and natural anti-inflammatory properties. Pure HA, ion-doped HA, and HA-polymer composites are investigated, but critical limitations such as brittleness remain; numerous efforts are being made to address them. Herein, the novel self-crystallization of a polymeric single-stranded deoxyribonucleic acid (ssDNA) without additional phosphate ions for synthesizing deoxyribonucleic apatite (DNApatite) is presented.
