Background: The Bosniak classification for cystic renal masses has undergone refinements since its inception. The 2019 version provides more objective criteria to enhance interrater agreement but needs validation. This study compares the interrater agreement of the 2005 and 2019 Bosniak classifications for cystic renal masses.

Chronic β3-AR stimulation activates distinct thermogenic mechanisms in brown and white adipose tissue and improves systemic metabolism in aged mice.

Adipose thermogenesis has been actively investigated as a therapeutic target for improving metabolic dysfunction in obesity. However, its applicability to middle-aged and older populations, which bear the highest obesity prevalence in the United States (approximately 40%), remains uncertain due to age-related decline in thermogenic responses. In this study, we investigated the effects of chronic thermogenic stimulation using the β3-adrenergic (AR) agonist CL316,243 (CL) on systemic metabolism and adipose function in aged (18-month-old) C57BL/6JN mice.

Citrulline and ADI-PEG20 reduce inflammation in a juvenile porcine model of acute endotoxemia.

Background: Arginine is a conditionally essential amino acid that is depleted in critically ill or surgical patients. In pediatric and adult patients, sepsis results in an arginine-deficient state, and the depletion of plasma arginine is associated with greater mortality. However, direct supplementation of arginine can result in the excessive production of nitric oxide (NO), which can contribute to the hypotension and macrovascular hypo-reactivity observed in septic shock.

The role of NOS3-rs1799983 and NOS3- rs2070744 SNP in occurrence of avascular necrosis as a post COVID-19 complication.

Avascular necrosis (AVN) is a debilitating condition characterized by bone tissue death due to inadequate blood supply, leading to joint dysfunction and collapse. This study investigates the potential association between AVN and COVID-19, focusing on genetic factors such as NOS3 polymorphisms. A total of 180 individuals were included, comprising 120 COVID-19 patients and 60 healthy controls.

Nasal Septum Deviation in Patients with Acute Invasive Fungal Rhinosinusitis in a Tertiary Care Hospital: A Cross-Sectional Study.

This is a retrospective study exploring the demographics and the role of nasal septum deviation in acute invasive fungal rhinosinusitis (AIFS); and if this deviation contributes to the laterality predilection of this opportunistic infection. Fifty-six craniofacial CT scans were evaluated by two radiologists blinded to the clinical data and outcome for laterality of the disease; and nasal septal deviation (NSD). NSD was graded based on the measured septal angle of deviation into mild, moderate, and severe and furtherly classified into one of seven types based on Mladina's classification.

The metabolic benefits of thermogenic stimulation are preserved in aging.

Adipose thermogenesis has been actively investigated as a therapeutic target for improving metabolic dysfunction in obesity. However, its applicability to middle-aged and older populations, which bear the highest obesity prevalence in the US (approximately 40%), remains uncertain due to age-related decline in thermogenic responses. In this study, we investigated the effects of chronic thermogenic stimulation using the β3-adrenergic (AR) agonist CL316,243 (CL) on systemic metabolism and adipose function in aged (18-month-old) C57BL/6JN mice.

Quality and Readability of Online Health Information on Common Urologic Cancers: Assessing Barriers to Health Literacy in Urologic Oncology.

Introduction: A growing number of Americans search online for health information related to urologic oncologic care each year. The American Medical Association recommends that medical information be written at a maximum sixth-grade level in order to be comprehensible by the majority of patients. As such, it is important to assess the quality and readability of online patient education material that patients are being exposed to.

Effects of improved amino acid balance diet on lysine mammary utilization, whole body protein turnover and muscle protein breakdown on lactating sows.

Background: The study objective was to test the hypothesis that low crude protein (CP) diet with crystalline amino acids (CAA) supplementation improves Lys utilization efficiency for milk production and reduces protein turnover and muscle protein breakdown. Eighteen lactating multiparous Yorkshire sows were allotted to 1 of 2 isocaloric diets (10.80 MJ/kg net energy): control (CON; 19.

Endoscopic Assisted Caldwell-Luc Approach for Total Excision of an Extensive Aneurysmal Bony Cyst of the Maxillary Sinus.

Aneurysmal bone cysts (ABCs) are uncommon lesions in head and neck area that could be primary or secondary in origin. The main problem with the traditional curettage and debridement is the high rates of recurrence, and cosmetic disfigurement with the open approach. In this article, we describe the use of a combined endoscopic sinus surgery and endoscopic assisted Caldwell approach to achieve a complete surgical excision of left maxillary sinus ABC extending to the left infratemporal fossa, and to avoid facial disfigurement in a 13-year-old female patient presented to our hospital with diplopia, facial pain, and headache.

Primary Retroperitoneal Lymph Node Dissection for Stage II Seminoma: Is Surgery the New Path Forward?

Purpose: On the basis of National Comprehensive Cancer Network guidelines, clinical stage (CS) II seminoma is treated with radiotherapy or chemotherapy. Primary retroperitoneal lymph node dissection (RPLND) demonstrated recent success as first-line therapy for RP-only disease. Our aim was to confirm surgical efficacy and evaluate recurrences after primary RPLND for CS IIA/IIB seminoma to determine if various clinical factors could predict recurrences.

Endoscopic Transnasal Transmaxillary Approach to Orbital Apex through the Meningo-Orbital Band: A Cadaveric Feasibility Study.

Background: Extradural transcranial release of the meningo-orbital band occupying the lateral part of the superior orbital fissure is used to approach the orbital apex and middle cranial fossa. The authors tested the feasibility of the release of the meningo-orbital band via an endonasal transmaxillary approach.

Materials And Methods: Five injected cadaveric heads were assessed for dimensions of superior orbital fissure by computerized tomography.

MYCN-driven fatty acid uptake is a metabolic vulnerability in neuroblastoma.

Neuroblastoma (NB) is a childhood cancer arising from sympatho-adrenal neural crest cells. MYCN amplification is found in half of high-risk NB patients; however, no available therapies directly target MYCN. Using multi-dimensional metabolic profiling in MYCN expression systems and primary patient tumors, we comprehensively characterized the metabolic landscape driven by MYCN in NB.

Primary Retroperitoneal Lymph Node Dissection for Patients With Pathologic Stage II Nonseminomatous Germ Cell Tumor-N1, N2, and N3 Disease: Is Adjuvant Chemotherapy Necessary?

Purpose: According to National Comprehensive Cancer Network guidelines, adjuvant chemotherapy (AC) has been advocated after primary retroperitoneal lymph node dissection (RPLND) to reduce the risk of relapse in pathologic nodal (pN) stage pN2 or pN3, whereas surveillance is preferred for pN1. We sought to explore the oncologic efficacy of primary RPLND alone for pathologic stage II in nonseminomatous germ cell tumors (NSGCTs) to reduce overtreatment with chemotherapy.

Methods: Patients with pathologic stage II NSGCT after primary RPLND between 2007 and 2017 were identified.

Does pathological sub stratification of T2 bladder cancer predict outcome in a contemporary pure urothelial carcinoma cohort?

Introduction: Studies evaluating outcomes in bladder cancer sub stratified into T2a and T2b pathologic staging have demonstrated inconsistent results. Survival outcomes in a cohort of pure urothelial carcinoma patient undergoing radical cystectomy were evaluated to determine the prognostic value of T2 sub staging.

Methods: Using our prospectively maintained institutional cystectomy database, we identified patients with pure urothelial carcinoma of the bladder, either pT2aN0 or pT2bN0.

Morphometric comparison of Fisch type A and endoscopic endonasal far-medial supracondylar approaches to the jugular foramen.

Objective: The jugular foramen (JF) is one of the most complex and challenging skull base regions to approach surgically. The extreme medial approach to access the JF provides the approach angle from an anterior direction and does not require dissection and sacrifice of the jugular bulb (JB) to reach the pars nervosa. The authors compared the Fisch type A approach to the extreme medial approach to access the JF and evaluated the usefulness of the extreme medial approach.

Correcting for sparsity and interdependence in glycomics by accounting for glycan biosynthesis.

Glycans are fundamental cellular building blocks, involved in many organismal functions. Advances in glycomics are elucidating the essential roles of glycans. Still, it remains challenging to properly analyze large glycomics datasets, since the abundance of each glycan is dependent on many other glycans that share many intermediate biosynthetic steps.

Restoration of the molecular clock is tumor suppressive in neuroblastoma.

MYCN activation is a hallmark of advanced neuroblastoma (NB) and a known master regulator of metabolic reprogramming, favoring NB adaptation to its microenvironment. We found that the expression of the main regulators of the molecular clock loops is profoundly disrupted in MYCN-amplified NB patients, and this disruption independently predicts poor clinical outcome. MYCN induces the expression of clock repressors and downregulates the one of clock activators by directly binding to their promoters.
