Purpose: This study explored the impact of Next Generation NCLEX (NGN)-style case studies on baccalaureate nursing students' self-confidence and anxiety with clinical decision-making.

Methods: Seventy-six second-year baccalaureate nursing students participated in this 1-group convergent mixed-methods study.

The Arduous Path Toward Equitable Access to Endocrinology Care.

Multiple factors contribute to the widening gap between supply and demand of endocrinology services. In addition to the inadequate growth of the workforce, the inefficient utilization of endocrinologists' expertise coupled with the rising prevalence of endocrine conditions has generated a crisis in access to specialty care. This mismatch is magnified in underserved communities and among certain racial/ethnic groups that carry a disproportionate burden of chronic diseases, like diabetes and osteoporosis, thus perpetuating the cycle of health disparities in vulnerable populations.

Exercise training and cold exposure trigger distinct molecular adaptations to inguinal white adipose tissue.

Exercise training and cold exposure both improve systemic metabolism, but the mechanisms are not well established. Here, we tested the hypothesis that inguinal white adipose tissue (iWAT) adaptations are critical for these beneficial effects and determined the impact of exercise-trained and cold-exposed iWAT on systemic glucose metabolism and the iWAT proteome and secretome. Transplanting trained iWAT into sedentary mice improves glucose tolerance, while cold-exposed iWAT transplantation shows no such benefit.

Sexual dimorphism and the multi-omic response to exercise training in rat subcutaneous white adipose tissue.

Subcutaneous white adipose tissue (scWAT) is a dynamic storage and secretory organ that regulates systemic homeostasis, yet the impact of endurance exercise training (ExT) and sex on its molecular landscape is not fully established. Utilizing an integrative multi-omics approach, and leveraging data generated by the Molecular Transducers of Physical Activity Consortium (MoTrPAC), we show profound sexual dimorphism in the scWAT of sedentary rats and in the dynamic response of this tissue to ExT. Specifically, the scWAT of sedentary females displays -omic signatures related to insulin signaling and adipogenesis, whereas the scWAT of sedentary males is enriched in terms related to aerobic metabolism.

SMYD3: a new regulator of adipocyte precursor proliferation at the early steps of differentiation.

Background: In obesity, adipose tissue undergoes a remodeling process characterized by increased adipocyte size (hypertrophia) and number (hyperplasia). The ability to tip the balance toward the hyperplastic growth, with recruitment of new fat cells through adipogenesis, seems to be critical for a healthy adipose tissue expansion, as opposed to a hypertrophic growth that is accompanied by the development of inflammation and metabolic dysfunction. However, the molecular mechanisms underlying the fine-tuned regulation of adipose tissue expansion are far from being understood.

Epidemiology of limb trauma interventions in France: Current state and future projections.

Context: The distributions and projections of trauma, treated according to the anatomical region, have not been studied in France. The objectives of this study were to obtain French epidemiological data specific to trauma procedures in orthopedic surgery, as well as to establish a statistical trend on the evolution of medical and surgical procedures resulting from this, since 2013 and over the years to come. Our hypothesis was that an increasing trend in trauma procedures since 2013 exists, with an epidemiological forecast of a continuing increase over 50 years, mainly in the context of the management of osteoporotic fractures related to the ageing French population.

Development of High-Loading Trastuzumab PLGA Nanoparticles: A Powerful Tool Against HER2 Positive Breast Cancer Cells.

Background: Trastuzumab, a therapeutic monoclonal antibody directed against HER2, is routinely used to treat HER2-positive breast cancer with a good response rate. However, concerns have arisen in the clinical practice due to adverse side effects. One way to overcome these limitations is to encapsulate trastuzumab in nanoparticles to improve cytotoxic activity, increase intracellular drug concentrations, escape the immune system and avoid systemic degradation of the drug in vivo.

Exercise Training and Cold Exposure Trigger Distinct Molecular Adaptations to Inguinal White Adipose Tissue.

Exercise training and cold exposure both improve systemic metabolism, but the mechanisms are not well-established. We tested the hypothesis that adaptations to inguinal white adipose tissue (iWAT) are critical for these beneficial effects by determining the impact of exercise-trained and cold-exposed iWAT on systemic glucose metabolism and the iWAT proteome and secretome. Transplanting trained iWAT into sedentary mice improved glucose tolerance, while cold-exposed iWAT transplantation showed no such benefit.

Sorafenib-Loaded PLGA Carriers for Enhanced Drug Delivery and Cellular Uptake in Liver Cancer Cells.

Introduction: Currently, conventional treatments of hepatocellular carcinoma (HCC) are not selective enough for tumor tissue and lead to multidrug resistance and drug toxicity. Although sorafenib (SOR) is the standard first-line systemic therapy approved for the clinical treatment of HCC, its poor aqueous solubility and rapid clearance result in low absorption efficiency and severely limit its use for local treatment.

Methods: Herein, we present the synthesis of biodegradable polymeric Poly (D, L-Lactide-co-glycolide) (PLGA) particles loaded with SOR (PS) by emulsion-solvent evaporation process.

Partial-Length Treatment With Brachytherapy in Patients With Endometrial Cancer With High-Risk Features Is as Effective as Full-Length Vaginal Brachytherapy but With Reduced Toxicity.

Purpose: Full-length vaginal (FLV) brachytherapy for patients with endometrial cancer and high-risk features should be considered as per the American Brachytherapy Society to reduce distal vaginal recurrence in patients with endometrial cancers with papillary serous/clear cell histologies, grade 3 status, or extensive lymphovascular invasion. We sought to investigate this patient population and report outcomes of treatment with high-dose-rate (HDR) brachytherapy in women treated with FLV brachytherapy versus partial-length vaginal (PLV) brachytherapy.

Methods And Materials: With institutional review board approval, we identified patients with endometrial cancer meeting American Brachytherapy Society criteria of high-risk features treated with adjuvant HDR between 2004 and 2010.

Exercise training remodels inguinal white adipose tissue through adaptations in innervation, vascularization, and the extracellular matrix.

Inguinal white adipose tissue (iWAT) is essential for the beneficial effects of exercise training on metabolic health. The underlying mechanisms for these effects are not fully understood, and here, we test the hypothesis that exercise training results in a more favorable iWAT structural phenotype. Using biochemical, imaging, and multi-omics analyses, we find that 11 days of wheel running in male mice causes profound iWAT remodeling including decreased extracellular matrix (ECM) deposition and increased vascularization and innervation.

Sexual dimorphism and the multi-omic response to exercise training in rat subcutaneous white adipose tissue.

Subcutaneous white adipose tissue (scWAT) is a dynamic storage and secretory organ that regulates systemic homeostasis, yet the impact of endurance exercise training and sex on its molecular landscape has not been fully established. Utilizing an integrative multi-omics approach with data generated by the Molecular Transducers of Physical Activity Consortium (MoTrPAC), we identified profound sexual dimorphism in the dynamic response of rat scWAT to endurance exercise training. Despite similar cardiorespiratory improvements, only male rats reduced whole-body adiposity, scWAT adipocyte size, and total scWAT triglyceride abundance with training.

Male nursing students' experiences during prelicensure education: An integrative review.

Background: Males represent less than 10 % of the global nursing workforce. To increase the recruitment and representation of male nurses, their experiences in prelicensure nursing education must be understood.

Objectives: The purpose of this integrative review was to explore literature related to male nursing students' experiences during prelicensure education.

Hydrogel Microparticles for Fluorescence Detection of miRNA in Mix-Read Bioassay.

Herein we describe the development of a mix-read bioassay based on a three-dimensional (3D) poly ethylene glycol-(PEG)-hydrogel microparticles for the detection of oligonucleotides in complex media. The key steps of hydrogels synthesis and molecular recognition in a 3D polymer network are elucidated. The design of the DNA probes and their density in polymer network were opportunely optimized.

Human Serum Albumin Nanoparticles as a Carrier for On-Demand Sorafenib Delivery.

Background: Drug delivery systems based on Human Serum Albumin (HSA) have been widely investigated due to their capability to interact with several molecules together with their nontoxicity, non-immunogenicity and biocompatibility. Sorafenib (SOR) is a kinase inhibitor used as the firstline treatment in hepatic cancer. However, because of its several intrinsic drawbacks (low solubility and bioavailability), there is a growing need for discovering new carriers able to overcome the current limitations.

Small Oligonucleotides Detection in Three-Dimensional Polymer Network of DNA-PEG Hydrogels.

The control of the three-dimensional (3D) polymer network structure is important for permselective materials when specific biomolecule detection is needed. Here we investigate conditions to obtain a tailored hydrogel network that combines both molecular filtering and molecular capture capabilities for biosensing applications. Along this line, short oligonucleotide detection in a displacement assay is set within PEGDA hydrogels synthetized by UV radical photopolymerization.

Surveillance Only for High-risk FIGO Stage IA/IB Malignant Ovarian Germ Cell Tumors: Results From a National Cancer Database.

Objectives: Investigate the use and outcomes of a surveillance only strategy for patients with high-risk stage I malignant ovarian germ cell tumors.

Methods: Patients with International Federation of Gynecology and Obstetrics stage IA/IB grade 2 or 3 immature teratoma, yolk sac, or mixed germ cell tumor diagnosed between 2004 and 2014 who had at least 1 month of follow-up were drawn from the National Cancer Database. Overall survival (OS) was evaluated for each histologic subtype using Kaplan-Meier curves, and compared with the log-rank test.

DBnorm as an R package for the comparison and selection of appropriate statistical methods for batch effect correction in metabolomic studies.

As a powerful phenotyping technology, metabolomics provides new opportunities in biomarker discovery through metabolome-wide association studies (MWAS) and the identification of metabolites having a regulatory effect in various biological processes. While mass spectrometry-based (MS) metabolomics assays are endowed with high throughput and sensitivity, MWAS are doomed to long-term data acquisition generating an overtime-analytical signal drift that can hinder the uncovering of real biologically relevant changes. We developed "dbnorm", a package in the R environment, which allows for an easy comparison of the model performance of advanced statistical tools commonly used in metabolomics to remove batch effects from large metabolomics datasets.

Clinicopathologic features of endometrial cancer with mismatch repair deficiency.

The inclusion of DNA mismatch repair (MMR) evaluation as a standard of care for endometrial cancer management will result in a growing population of patients with MMR deficiency and negative germline Lynch syndrome testing (MMR-deficient). In this systematic review and study, the clinicopathologic features of endometrial cancer in patients with MMR-intact, MLH1 methylation positive, MMR-deficient or Lynch syndrome are evaluated. A systematic search of online databases between 1990 and 2018 identified studies of endometrial cancer patients with tumour testing (MMR protein immunohistochemistry or microsatellite instability) and germline assessment for Lynch syndrome.

Is hysterectomy necessary for the treatment of preinvasive stratified mucin producing intraepithelial lesions of the cervix?

Objectives: Stratified mucin producing intraepithelial lesion (SMILE) is an uncommon premalignant cervical intraepithelial lesion, characterized by histopathologic features resembling those observed in high grade squamous intraepithelial lesions and adenocarcinoma in situ of the cervix. Its hybrid morphology poses a pathologic challenge with no specific management guidelines. The goal of this study was to review the natural history of SMILE and treatment based outcomes.

Outcomes of minimally invasive surgery for patients with endometrial carcinoma involving the cervix.

Objective: Most studies evaluating the oncologic safety of minimally invasive surgery for endometrial cancer focus on patients with stage I disease. The aim of this study was to investigate the outcomes of minimally invasive surgery for patients with endometrial carcinoma involving the cervix.

Methods: Patients diagnosed between January 2010 and December 2015, with clinical stage II endometrial carcinoma, who underwent hysterectomy with lymphadenectomy, were drawn from the National Cancer Database.

Anti-adipogenic signals at the onset of obesity-related inflammation in white adipose tissue.

Chronic inflammation that affects primarily metabolic organs, such as white adipose tissue (WAT), is considered as a major cause of human obesity-associated co-morbidities. However, the molecular mechanisms initiating this inflammation in WAT are poorly understood. By combining transcriptomics, ChIP-seq and modeling approaches, we studied the global early and late responses to a high-fat diet (HFD) in visceral (vWAT) and subcutaneous (scWAT) AT, the first being more prone to obesity-induced inflammation.

Primary total hip replacement in Ficat-Arlet stage 3 and 4 osteonecrosis: a retrospective study at a minimum 12-year follow-up.

Introduction: Results of total hip replacement (THR) for aseptic osteonecrosis are controversial and conflicting according to implant type and generation. The present study consisted in a retrospective assessment of implant survival in primary THR for aseptic osteonecrosis, using a cemented stem, standard polyethylene press-fit acetabular component, and metal-metal bearing. The study hypothesis was that THR results are equivalent between aseptic osteonecrosis and osteoarthritis of the hip.

Low-grade serous ovarian cancer: State of the science.

In January 2019, a group of basic, translational, and clinical investigators and patient advocates assembled in Miami, Florida, to discuss the current state of the science of low-grade serous carcinoma of the ovary or peritoneum-a rare ovarian cancer subtype that may arise de novo or following a diagnosis of serous borderline tumor. The purpose of the conference was to review current knowledge, discuss ongoing research by established researchers, and frame critical questions or issues for future directions. Following presentations and discussions, the primary objective was to initiate future collaborations, uniform database platforms, laboratory studies, and clinical trials to better understand this disease and to advance clinical care outside the boundaries of single academic institutions.

Primary malignant ovarian carcinoid; management and outcomes.

Objective: To investigate the clinicopathological characteristics and survival of patients with malignant ovarian carcinoid tumor (OC).

Materials And Methods: The National Cancer Database was accessed and patients diagnosed between 2004 and 2015 with a OC who did not have a personal history of a tumor at another site were selected. Overall survival (OS) was assessed for patients who had ≥1 month of follow-up.
