CircRNA_30032 promotes renal fibrosis in UUO model mice via miRNA-96-5p/HBEGF/KRAS axis.

In this study, we investigated the role of circular RNA_30032 (circRNA_30032) in renal fibrosis and the underlying mechanisms. The study was carried out using TGF-β1-induced BUMPT cells and unilateral ureteral obstruction (UUO)-induced mice, respectively, as and models. CircRNA_30032 expression was significantly increased by 9.

MBD2 Mediates Septic AKI through Activation of PKCη/p38MAPK and the ERK1/2 Axis.

Our previous study demonstrated that the methyl-CpG-binding domain protein 2 (MBD2) mediates vancomycin (VAN)-induced acute kidney injury (AKI). However, the role and regulation of MBD2 in septic AKI are unknown. Herein, MBD2 was induced by lipopolysaccharide (LPS) in Boston University mouse proximal tubules (BUMPTs) and mice.

The Biomarker TCONS_00016233 Drives Septic AKI by Targeting the miR-22-3p/AIFM1 Signaling Axis.

The prediction of mortality for septic acute kidney injury (AKI) has been assessed by a number of potential biomarkers, including long noncoding RNAs (lncRNAs). However, the validation of lncRNAs as biomarkers, particularly for the early stages of septic AKI, is still warranted. Our results indicate that the lncRNA TCONS_00016233 is upregulated in plasma of sepsis-associated non-AKI and AKI patients, but a higher cutoff threshold (9.

EGFR drives the progression of AKI to CKD through HIPK2 overexpression.

The molecular mechanism underlying the transition of acute kidney injury (AKI) to chronic kidney disease (CKD) induced by vancomycin (VAN) remains largely unknown. : The mice model of VAN drives AKI to CKD was developed to investigate the role and molecular mechanism of epidermal growth factor receptor (EGFR). The EGF receptor mutant (Wa-2) mice and gefitinib were used to inactivation of EGFR.

Insurance Companies Fighting the Peer Review Empire without any Validity: the Case for Addiction and Pain Modalities in the face of an American Drug Epidemic.

The United States are amid an opioid overdose epidemic; we are challenged to provide non-addicting/non-pharmacological alternatives to assist in pain attenuation. There are proven strategies available to manage chronic pain effectively without opioids. Utilization review providers for insurance companies often ignore medicine based scientific peer-reviewed studies that warn against the chronic use of opioid medications, as well as the lack of evidence to support long-term use of opioids for pain.

MBD2 upregulates miR-301a-5p to induce kidney cell apoptosis during vancomycin-induced AKI.

Despite DNA methylation occurred in acute kidney injury (AKI), how it influenced progression of AKI remains unclear. Methyl-CpG-binding domain protein 2 (MBD2), a protein readers of methylation, was used to analyze the impact of DNA methylation on vancomycin (VAN)-induced AKI. Here, in cultured human kidney tubular epithelial cells (HK-2), we show that knockdown of MBD2 by siRNA attenuated VAN-induced apoptosis, caspase activity, and the expression of BAX and cleaved caspase 3.

ACR Appropriateness Criteria Chronic Back Pain Suspected Sacroiliitis-Spondyloarthropathy.

Inflammatory sacroiliitis or the seronegative axial spondyloarthropathies often presents as back pain or sacroiliac joint pain of more than 3-month duration with inflammatory symptoms and typically in patients younger than 45 years of age. Imaging plays an important role in diagnosis and disease monitoring. This article addresses the appropriate sequence of initial imaging for evaluation of a suspected spondyloarthropathy, the imaging follow-up of treatment response and the special considerations for imaging of trauma in patients with ankylosis of the spine.

ACR Appropriateness Criteria Suspected Osteomyelitis, Septic Arthritis, or Soft Tissue Infection (Excluding Spine and Diabetic Foot).

Infection of the musculoskeletal system is a common clinical problem. Differentiating soft tissue from osseous infection often determines the appropriate clinical therapeutic course. Radiographs are the recommend initial imaging examination, and although often not diagnostic in acute osteomyelitis, can provide anatomic evaluation and alternative diagnoses influencing subsequent imaging selection and interpretation.

ACR Appropriateness Criteria Stress (Fatigue/Insufficiency) Fracture, Including Sacrum, Excluding Other Vertebrae.

Stress fractures, including both fatigue and insufficiency types, are frequently encountered in clinical practice as a source of pain in both athletes and patients with predisposing conditions. Radiography is the imaging modality of choice for baseline diagnosis. MRI has greatly improved our ability to diagnose radiographically occult stress fractures.

p53 activates miR-192-5p to mediate vancomycin induced AKI.

Pathogenic role of p53 in AKI remains controversial and the underlying mechanism is unclear. Here, we tested whether the inhibition of p53 may ameliorate vancomycin (VAN) induced acute kidney injury (AKI). Mice with p53 knock out (p53-KO) were resistant to VAN induced AKI, indicated by the analysis of renal function, histology, and apoptosis.

Can Residents Assess Other Providers' Infant Lumbar Puncture Skills?: Validity Evidence for a Global Rating Scale and Subcomponent Skills Checklist.

Objectives: The aims of this study were to provide validity evidence for infant lumbar puncture (ILP) checklist and global rating scale (GRS) instruments when used by residents to assess simulated ILP performances and to compare these metrics to previously obtained attending rater data.

Methods: In 2009, the International Network for Simulation-based Pediatric Innovation, Research, and Education (INSPIRE) developed checklist and GRS scoring instruments, which were previously validated among attending raters when used to assess simulated ILP performances. Video recordings of 60 subjects performing an LP on an infant simulator were collected; 20 performed by subjects in 3 categories (beginner, intermediate, and expert).

Mitochondrial dysfunction in obesity-related kidney disease: a novel therapeutic target.

Lipid accumulation in renal cells has been implicated in the pathogenesis of obesity-related kidney disease, but the underlying mechanism is poorly understood. Szeto et al. now unravel a central role of mitochondrial dysfunction in a high fat diet-induced glomerulopathy and proximal tubular injury.

Blepharochalasis: something to cry about.

Blepharochalasis is a rare disorder of unknown etiology defined by loose, atrophic periorbital skin following recurrent episodes of eyelid edema. Characteristic histopathology shows complete absence of elastic fibers. The current case progressed after multiple episodes of crying, which may be related to matrix metalloproteinase dysregulation.

Computational analysis of swallowing mechanics underlying impaired epiglottic inversion.

Objectives/hypothesis: Determine swallowing mechanics associated with the first and second epiglottic movements, that is, movement to horizontal and full inversion, respectively, to provide a clinical interpretation of impaired epiglottic function.

Neurocognitive and behavioral profiles of children with Landau-Kleffner syndrome.

This is a retrospective study of 14 cases of children with Landau-Kleffner syndrome (LKS), the most prominent feature of which is acquired aphasia. These children were followed at a tertiary care pediatric epilepsy center. From the research data base, all LKS cases with neuropsychological evaluation were extracted.

The Pretreatment Neutrophil/Lymphocyte Ratio Is Associated with All-Cause Mortality in Black and White Patients with Non-metastatic Breast Cancer.

The pretreatment neutrophil/lymphocyte ratio (NLR), derived from differential white blood cell counts, has been previously associated with poor prognosis in breast cancer. Little data exist, however, concerning this association in Black patients, who are known to have lower neutrophil counts than other racial groups. We conducted a retrospective cohort study of 236 Black and 225 non-Hispanic White breast cancer patients treated at a single institution.

Head and neck chondrosarcomas: Analysis of the Surveillance, Epidemiology, and End Results database.

Background: Chondrosarcoma is a rare tumor of the head and neck. Because of the limited clinical data, no studies have conducted a thorough comparison between head and neck chondrosarcomas and those arising at other body sites.

Methods: Using the Surveillance, Epidemiology, and End Results (SEER) database, we compared 682 patients with chondrosarcomas of the head and neck with 4757 patients with non-head and neck chondrosarcomas, evaluating disease-specific survival (DSS) and overall survival (OS) based on tumor location, histology, grade, stage, and treatment.

Dietary Patterns and Fractures in Postmenopausal Women: Results From the Women's Health Initiative.

Importance: Considerable efforts have been undertaken to relate single nutrients to bone health. To this point, results are inconsistent. Suboptimal single nutrient intake does not occur in isolation but rather reflects a poor diet quality.

Impaired swallowing mechanics of post radiation therapy head and neck cancer patients: A retrospective videofluoroscopic study.

Aim: To determine swallowing outcomes and hyolaryngeal mechanics associated with post radiation therapy head and neck cancer (rtHNC) patients using videofluoroscopic swallow studies.

Methods: In this retrospective cohort study, videofluoroscopic images of rtHNC patients (n = 21) were compared with age and gender matched controls (n = 21). Penetration-aspiration of the bolus and bolus residue were measured as swallowing outcome variables.

Leptin Induces Hypertension and Endothelial Dysfunction via Aldosterone-Dependent Mechanisms in Obese Female Mice.

Obesity is a major risk factor for cardiovascular disease in males and females. Whether obesity triggers cardiovascular disease via similar mechanisms in both the sexes is, however, unknown. In males, the adipokine leptin highly contributes to obesity-related cardiovascular disease by increasing sympathetic activity.

Ptp1b deletion in pro-opiomelanocortin neurons increases energy expenditure and impairs endothelial function via TNF-α dependent mechanisms.

Protein tyrosine phosphatase 1b (Ptp1b) is a negative regulator of leptin and insulin-signalling pathways. Its targeted deletion in proopiomelanocortin (POMC) neurons protects mice from obesity and diabetes by increasing energy expenditure. Inflammation accompanies increased energy expenditure.

Barriers to outpatient stress testing follow-up for low-risk chest pain patients presenting to an ED chest pain unit.

Introduction: Outpatient stress testing (OST) after evaluation in the emergency department (ED) is an acceptable evaluation method for patients presenting to the ED with low-risk chest pain (CP). However, not all patients return for OST. Barriers to follow-up evaluation exist and are poorly understood.
