De-Escalation of Nodal Surgery in Clinically Node-Positive Breast Cancer.

JAMA Surg

January 2025

Breast Unit, Department of General Surgery, Istanbul Faculty of Medicine, Istanbul University, Istanbul, Türkiye.

Importance: Increasing evidence supports the oncologic safety of de-escalating axillary surgery for patients with breast cancer after neoadjuvant chemotherapy (NAC).

Objective: To evaluate the oncologic outcomes of de-escalating axillary surgery among patients with clinically node (cN)-positive breast cancer and patients whose disease became cN negative after NAC (ycN negative).

Design, Setting, And Participants: In the NEOSENTITURK MF-1803 prospective cohort registry trial, patients from 37 centers with cT1-4N1-3M0 disease treated with sentinel lymph node biopsy (SLNB) or targeted axillary dissection (TAD) alone or with ypN-negative or ypN-positive disease after NAC were recruited between February 15, 2019, and January 1, 2023, and evaluated.

Importance: Facial synkinesis refers to pathologic cocontraction and baseline hypertonicity of muscles innervated by the facial nerve, commonly attributed to the aberrant regeneration of nerve fibers following injury. The pathomechanism and optimal treatment of facial synkinesis remain unclear. The goal of this review is to highlight current understanding of the epidemiology, pathophysiology, clinical presentation, assessment, and treatment of facial synkinesis.

We aimed to explore the role of Amino acid metabolism (AAM) and identify biomarkers for prognosis management and treatment of lung adenocarcinoma. Differentially expressed genes (DEGs) associated with AAM in lung adenocarcinoma were selected from public databases. Samples were clustered into varying subtypes using ConsensusClusterPlus based on gene levels.

Objectives: A recent coronavirus-related factory shutdown led to a global shortage of iodinated contrast. The authors evaluated how the contrast shortage impacted percutaneous coronary interventions (PCI).

Methods: Using a statewide database incorporating CathPCI registry data from 19 hospitals, the authors evaluated 2 time periods: pre-shortage (May 1, 2021 - April 30, 2022) and during the shortage (May 1, 2022 - October 31, 2022).

Importance: While urban counties maintain higher densities of ophthalmologists than rural counties, the geographic distribution of ophthalmic surgical subspecialists has not yet been elucidated. A potential workforce discrepancy may impact the burden of care faced by rural surgeons.

Objective: To assess the geographic distribution of the ophthalmic subspecialist surgeon workforce and evaluate factors associated with practicing in rural areas.

Importance: Evolving breast cancer treatments have led to improved outcomes but carry a substantial financial burden. The association of treatment costs with the cost-effectiveness of screening mammography is unknown.

Objective: To determine the cost-effectiveness of population-based breast cancer screening in the context of current treatment standards.

Importance: Cardiovascular disease (CVD) and cancer are the leading causes of mortality in the US. Large-scale population-based and mechanistic studies support a direct effect of CVD on accelerated tumor growth and spread, specifically in breast cancer.

Objective: To assess whether individuals presenting with advanced breast cancers are more likely to have prevalent CVD compared with those with early-stage breast cancers at the time of diagnosis.

Importance: Growing trends in private equity acquisition of acute care hospitals in the US have motivated investigations into quality of care delivered at these health centers. While some studies have explored comparative outcomes for high-acuity medical conditions, care trends and outcomes of complex surgical procedures, such as esophagectomy, at private equity-acquired hospitals is unknown.

Objective: To compare structural characteristics and postoperative outcomes following esophagectomy between private equity-acquired and nonacquired health centers.

Background: Radiation segmentectomy (RS) is an alternative potential local curative treatment for selected colorectal liver metastases (CLMs) not amenable to ablation or limited resection.

Purpose: The aim of this study was to evaluate the dosimetric response of low volume CLMs to RS in heavily pretreated patients who are not candidates for resection or percutaneous ablation.

Patients And Methods: This single-center retrospective study evaluated CLMs patients treated with RS (prescribed tumor dose >190 Gy) from 2015 to 2023.

Background: Noncompressible truncal hemorrhage is a major contributor to preventable deaths in trauma patients and, despite advances in emergency care, still poses a big challenge.

Objectives: This study aimed to assess the clinical efficacy of trauma resuscitation care incorporating Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) compared to standard care for managing uncontrolled torso or lower body hemorrhage.

Methods: This study utilized a target trial design with a matched case-control methodology, emulating randomized 1 : 1 allocation for patients receiving trauma resuscitation care with or without the use of REBOA.

Purpose: The main objective of this study was to conduct a radioanatomical study of the osteo-myo-cutaneous scapulo-dorsal pedicled flap.

Methods: A radiological study was performed to study the anatomical variations of the dorsal scapular pedicle (origin, course of the deep branch of the dorsal scapular artery (DSA) in relation to the medial border of the scapula, perforators from the superficial branch of the DSA). Perforators from the superficial branch of the DSA were also identified on anatomical subjects, and their cutaneous vascular territory was determined.

Re-arranging the Cis-regulatory Modules of Hox Complex in Drosophila via FLP-FRT and CRISPR/Cas9.

Methods Mol Biol

January 2025

Department of Plastic and Reconstructive Surgery, Johns Hopkins University, Baltimore, MD, USA.

FLP-FRT, a well-established technique for genome manipulation, and the revolutionary CRISPR/Cas9, known for its targeted indels, are combined in a novel approach. This unique method is applied to the Hox genes in the Drosophila melanogaster bithorax complex, which are closely located to the cis-regulatory modules that define their spatial-temporal regulation. The number and position of these genes are directly correlated to their expression pattern.

This study aimed to test age-related changes in sternal fusion and sternal-rib cartilage ossification on multi-slice computed tomography (MSCT) images of the Croatian population. The additional aim was to develop models to estimate age and provide an interface for the model's application and validation. This retrospective study was conducted on 144 MSCT images of the sternal region, and the developed models were tested on 36 MSCT images.

Purpose: A novel theranostic radiopharmaceutical targeting prostate-specific membrane antigen (PSMA), [Ga]Ga/[Lu]Lu-NYM032, was developed and its diagnostic and therapeutic potential in the treatment of prostate cancer (PCa) was preliminarily evaluated.

Methods: The diagnostic efficacy of the PET tracer [Ga]Ga-NYM032 was first evaluated in PSMA-positive xenograft-bearing models (LNCaP models), followed by evaluation in 10 PCa patients using [Ga]Ga-PSMA617 a comparator. Finally, the therapeutic potential of [Lu]Lu-NYM032 was evaluated in LNCaP models.
