Long-term assessment of skeletal and dental asymmetry after conventional and mini-implant-assisted rapid palatal expansion.

Introduction: This study aimed to evaluate the short-term and long-term skeletal and dental asymmetry with miniscrew-assisted rapid palatal expansion (MARPE), rapid palatal expansion (RPE), and control group using cone-beam computed tomography (CBCT) analysis.

Methods: A total of 180 CBCT scans were analyzed for 60 patients divided into 3 groups: MARPE (mean age 13.7 ± 1.

Outcomes of a novel double-stapled anastomotic technique in esophagectomy.

The double-stapled () anastomotic technique associates with lower odds of anastomotic leak and stricture. , Single posterior stapled.

Nutrient-driven histone code determines exhausted CD8 T cell fates.

Exhausted T cells (TEX) in cancer and chronic viral infections undergo metabolic and epigenetic remodeling, impairing their protective capabilities. However, the impact of nutrient metabolism on epigenetic modifications that control TEX differentiation remains unclear. We showed that TEX cells shifted from acetate to citrate metabolism by downregulating acetyl-CoA synthetase 2 (ACSS2) while maintaining ATP-citrate lyase (ACLY) activity.

Imaging Findings and Management Strategies for Liver Masses in Children with Predisposition Disorders: A Review by the Pediatric LI-RADS Group.

Liver masses in children with underlying systemic disease or a predisposing syndrome can be benign or malignant, ranging from focal fat to hepatocellular carcinoma (HCC). Knowledge of the underlying condition, the pathophysiologic effect on the liver, and the development of liver disease and specific liver lesions allows radiologists to guide imaging with regard to modality and frequency and give recommendations for biopsy when appropriate. In some predisposition disorders, such as Beckwith Wiedemann spectrum, familial adenomatous polyposis syndrome, and tuberous sclerosis complex, established guidelines for imaging screening exist.

Sinusitis and rhinitis among US veterans deployed to Southwest Asia and Afghanistan after September 11, 2001.

Background: Post-9/11 veterans were exposed to environmental and occupational pollutants during deployment.

Objective: Our aim was to determine associations between deployment-related exposures and sinusitis and rhinitis.

Methods: Between April 2018 and March 2020, veterans with land-based deployment after 9/11 who were living within 25 miles of 6 Department of Veteran Affairs medical centers were randomly chosen by using a Defense Manpower Data Center roster.

Surveillance, Epidemiology, and End Results Data Show Increasing Rates of Distant-Stage Breast Cancer at Presentation in U.S. Women.

Background The incidence of distant-stage (metastatic) breast cancer at initial presentation has increased significantly in U.S. women under 40 years of age, but no clear trend in older women has been reported.

The QIBA Profile for Dynamic Susceptibility Contrast MRI Quantitative Imaging Biomarkers for Assessing Gliomas.

The dynamic susceptibility contrast (DSC) MRI measures of relative cerebral blood volume (rCBV) play a central role in monitoring therapeutic response and disease progression in patients with gliomas. Previous investigations have demonstrated promise of using rCBV in classifying tumor grade, elucidating tumor viability after therapy, and differentiating pseudoprogression and pseudoresponse. However, the quantification and reproducibility of rCBV measurements across patients, devices, and software remain a critical barrier to routine or clinical trial use of longitudinal DSC MRI in patients with gliomas.

Ferroptosis exacerbates the clonal deletion of virus-specific exhausted CD8 T cells.

During chronic infection or tumorigenesis, persistent antigen stimulation contributes to the exhaustion of CD8 T cells. Nevertheless, exhausted CD8 T (T) cells still preserve certain effector function, and maintaining a reservoir of exhausted cells is of vital importance for virus elimination and tumor eradiation. Despite considerable work interrogating the rejuvenation of T cells, mechanisms underpinning the clonal deletion of T cells remain largely unexplored over the past decade.

Review/Perspective: Incidence and treatment of CSF leaks/dural tears (DT) occurring during anterior cervical surgery.

Background: The incidence of cerebrospinal fluid (CSF) leaks/dural tears (DT) occurring during anterior cervical diskectomy and fusion (ACDF) are typically relatively low. However, this frequency markedly increases when anterior corpectomy and fusion (ACF) are performed to address ossification of the posterior longitudinal ligament (OPLL).

Methods: The reported frequencies of CSF leaks/DT occurring during elective ACDF (i.

LI-RADS US Surveillance Version 2024 for Surveillance of Hepatocellular Carcinoma: An Update to the American College of Radiology US LI-RADS.

In 2017, the American College of Radiology introduced the US Liver Imaging Reporting and Data System (LI-RADS) as a framework for US surveillance of patients at risk for developing hepatocellular carcinoma. This has aided in the standardization of technique, clinical reporting, patient management, data collection, and research. Emerging evidence has helped inform changes to the algorithm, now released as LI-RADS US Surveillance version 2024.

Inborn errors of immunity reveal molecular requirements for generation and maintenance of human CD4 IL-9-expressing cells.

Background: CD4 T cells play essential roles in adaptive immunity. Distinct CD4 T-cell subsets-T1, T2, T17, T22, T follicular helper, and regulatory T cells-have been identified, and their contributions to host defense and immune regulation are increasingly well defined. IL-9-producing T9 cells were first described in 2008 and appear to play both protective and pathogenic roles in human immunity.
