Trans-arterial omental flap protection for infected femoral artery aneurysm in a patient with Parkes-Weber syndrome.

We report a case of a 75-year-old man diagnosed with Parkes-Weber syndrome with an infected common femoral artery aneurysm secondary to chronic venous ulcers and groin infection. Given the symptomatic and rapid enlargement of the aneurysm, emergency aneurysmectomy and crossover femoro-femoral bypass were performed with an omental flap routed intraluminally through the aneurysm of the ipsilateral external iliac artery. The transarterial route enabled the short-cutting of the omental flap and the potential prevention of infection in the adjacent external iliac artery.

Pivotal role of venous blood gas analysis in the detection of metabolic acidosis due to laxative abuse in an anorexia nervosa patient: A case report.

Background: Anorexia nervosa has the highest mortality rate of any psychiatric disorder, and purging behaviors can cause a fatal electrolyte and acid-base imbalance. Routine laboratory testing during inpatient care is essential because these patients often provide inaccurate information about their diet and purging behaviors. However, blood gas analysis for an acid-base evaluation is rarely performed in the psychiatric setting because psychiatrists are not accustomed to evaluating the results.

Functional Improvements by Controlled Suture Tension in Arthroscopic Rotator Cuff Repair.

Background: Although a certain degree of tension in bridging sutures is required for proper tendon healing following suture-bridge rotator cuff repair, excessive suture tension may be detrimental to tendon healing. This study aimed to investigate the effects of bridging suture tension on clinical outcomes and tendon healing. We hypothesized that fixed, low tension of the bridging sutures would improve the tendon healing rate and clinical outcomes compared with maximum manual tensioning.

Effect of Ripasudil on the Change Rates of the Circumpapillary Retinal Nerve Fiber Layer Thickness in Patients With Primary Open-Angle Glaucoma.

The effect of the Rho-kinase inhibitor ripasudil on the retinal optic nerve fiber layer (RNFL) remains unclear. We aimed to determine this effect in patients with primary open-angle glaucoma (POAG) using optical coherence tomography (OCT) measurements and linear mixed analysis. This study prospectively included outpatients from a single center with POAG without a history of vitreoretinal or glaucoma surgery from December 2014 to June 2020, in whom the circumpapillary RNFL thickness (cpRNFLT) was measured more than three times before and after ripasudil initiation, without additional medication or surgery during the period.

Multidetector-row Computed Tomography Analysis of the Radial Midpalmar Flap: A Retrospective Anatomical Study.

Background: Soft tissue defects on the palm side of the thumb can be effectively covered by using the radial midpalmar (RMP) flap, which is usually harvested as a pedicled flap. However, previous anatomical studies on this flap are limited. We analyzed multidetector-row computed tomography angiograms of the radial midpalm of hands to more precisely characterize the 3-dimensional anatomical structure of the perforators in living patients.

Activity-Regulated Cytoskeleton-Associated Protein Gene Expression Is Associated With High Infiltration of Stromal Cells and Immune Cells, but With Less Cancer Cell Proliferation and Better Overall Survival in Estrogen Receptor-Positive/Human Epidermal Growth Factor Receptor 2-Negative Breast Cancers.

Background: Peritumoral lidocaine infiltration prior to excision is associated with better survival in breast cancer (BC), which led us to hypothesize that innervation to the tumor affects its biology and patient survival. Activity-regulated cytoskeleton-associated protein (ARC) gene expression is known to be regulated by neuronal activity. Therefore, we studied the clinical relevance of ARC gene expression as a surrogate of neuronal activity in BC.

Gene Expression in Breast Cancer Is Associated With Worse Prognosis, but Better Response to Chemotherapy and Immunotherapy.

Background: Vascular endothelial growth factor-A (VEGFA) is a key inducer of angiogenesis, responsible for generating new blood vessels in the tumor microenvironment (TME) and facilitating metastasis. Notably, Avastin, which targets VEGFA, failed to demonstrate any significant benefit in clinical trials for breast cancer (BC). This study aimed to investigate the clinical relevance of gene expression in BC.

Introduction: Atrial fibrillation (AF) significantly detracts from health-related quality of life (HRQoL). Despite the promotion of exercise interventions for managing AF, the effectiveness of different exercise modalities remains to be clearly defined. This systematic review and network meta-analysis aims to evaluate the comparative effectiveness of various modes of exercise interventions on HRQoL in AF patients.

Adenosine deficiency facilitates CA1 synaptic hyperexcitability in the presymptomatic phase of a knockin mouse model of Alzheimer disease.

The disease's trajectory of Alzheimer disease (AD) is associated with and negatively correlated to hippocampal hyperexcitability. Here, we show that during the asymptomatic stage in a knockin (KI) mouse model of Alzheimer disease (APP; APPKI), hippocampal hyperactivity occurs at the synaptic compartment, propagates to the soma, and is manifesting at low frequencies of stimulation. We show that this aberrant excitability is associated with a deficient adenosine tone, an inhibitory neuromodulator, driven by reduced levels of CD39/73 enzymes, responsible for the extracellular ATP-to-adenosine conversion.

Raman signatures of type A and B influenza viruses: molecular origin of the "" inactivation mechanism mediated by micrometric silicon nitride powder.

A multiomic study of the structural characteristics of type A and B influenza viruses by means of highly spectrally resolved Raman spectroscopy is presented. Three virus strains, A H1N1, A H3N2, and B98, were selected because of their known structural variety and because they have co-circulated with variable relative prevalence within the human population since the re-emergence of the H1N1 subtype in 1977. Raman signatures of protein side chains tyrosine, tryptophan, and histidine revealed unequivocal and consistent differences for pH characteristics at the virion surface, while different conformations of two C-S bond configurations in and methionine rotamers provided distinct low-wavenumber fingerprints for different virus lineages/subtypes.

Impacts of Calculation Grid Spacing and Statistical Uncertainty of Monte Carlo Algorithm on Stereotactic Radiosurgery Planning With Volumetric-Modulated Arcs for Single Brain Metastases Using the Monaco® System.

Purpose In linac-based stereotactic radiosurgery (SRS) utilizing a multileaf collimator (MLC) for brain metastases (BMs), a volumetric-modulated arc (VMA) technique is indispensable for generating a suitable dose distribution with efficient planning and delivery. However, the optimal calculation grid spacing (GS) and statistical uncertainty (SU) of the Monte Carlo algorithm for VMA optimization have yet to be determined. This planning study aimed to examine the impacts of GS and GU settings on VMA-based SRS planning and to find the optimal combination for templating.

Evolutionary patterns and research frontiers in autophagy in podocytopathies: a bibliometric analysis.

Introduction: Podocytopathies are a uniquely renal disease syndrome, in which direct or indirect podocyte injury leads to proteinuria or nephrotic syndrome. Of the many factors that contribute to podocytopathies, the abnormal regulation of autophagy, such insufficient or excessive autophagy levels, have been proposed to play a significant role in the occurrence and development of podocytopathies. However, there still has been a lack of systematic and comparative research to elucidate exact role of autophagy in podocytopathies and its current research status.
