The Brussels consensus for non-invasive ICP monitoring when invasive systems are not available in the care of TBI patients (the B-ICONIC consensus, recommendations, and management algorithm).

Background: Invasive systems are commonly used for monitoring intracranial pressure (ICP) in traumatic brain injury (TBI) and are considered the gold standard. The availability of invasive ICP monitoring is heterogeneous, and in low- and middle-income settings, these systems are not routinely employed due to high cost or limited accessibility. The aim of this consensus was to develop recommendations to guide monitoring and ICP-driven therapies in TBI using non-invasive ICP (nICP) systems.

Ovarian clear cell carcinoma: open questions on the management and treatment algorithm.

Ovarian clear cell carcinoma (OCCC) accounts for ~10% of all epithelial ovarian cancers and is considered a different entity from the more common high-grade serous ovarian carcinoma (HGSC), with distinct clinical presentations, different risk, and prognostic factors, and specific molecular features. Most OCCCs are diagnosed at an early stage and show favorable outcomes, in contrast to those diagnosed at advanced stages, which exhibit intrinsic resistance to platinum-based chemotherapy regimens and a very poor prognosis. The standard treatment of advanced OCCC is currently based on primary debulking surgery followed by platinum-based chemotherapy according to recent international guidelines.

Tangential Versus Segmental Portomesenteric Venous Resection During Pancreatoduodenectomy for Pancreatic Cancer: An International Multicenter Cohort Study on Surgical and Oncological Outcome.

Objective: To investigate whether tangential versus segmental portomesenteric venous resection (PVR) impacts surgical and oncological outcome in patients undergoing pancreatoduodenectomy for pancreatic cancer with portomesenteric vein (PMV) involvement.

Summary Background Data: Current comparative studies on tangential versus segmental PVR as part of pancreatoduodenectomy for pancreatic cancer include all degrees of PMV involvement, including cases where tangential PVR may not be a feasible approach, limiting the clinical applicability.

Methods: International retrospective study in 10 centers from 5 countries, including all consecutive patients after pancreatoduodenectomy with PVR for pancreatic cancer with ≤180° PMV involvement on cross-sectional imaging at diagnosis (2014-2020).

Construction and Development of an Enhanced Recovery After Surgery Program for the Surgical Management of Patients With Spinal Metastasis: A Modified Delphi Study.

Objective: As an effective treatment for spinal metastasis (SM), ERAS protocol can significantly reduce the length of hospital stay and complications in patients. Establishing an ERAS program for perioperative care after SM surgery is a clinical problem that needs to be addressed urgently. We aimed to develop an Enhanced Recovery After Surgery (ERAS) program and Surgical Safety Checklist (SSC) that conferred clinical benefit to patients with SM and made it relatively easy to manage the condition.

Oncological Feasibility of Limited Neck Dissection in cN0 Supraglottic Laryngeal Cancer.

Background: Supraglottic squamous cell carcinoma (SCC) is a significant portion of head and neck cancers, with the management of clinically negative necks (cN0) through selective neck dissection (SND) being debated due to potential morbidities and low metastasis rates in levels IIb and IV.

Methods: This study is a retrospective, multicenter examination of the potential feasibility of limited neck dissection (LND), including only levels IIa and III in cN0 supraglottic SCC patients. It analyzed occult metastasis rates and explored relapse occurrences alongside potential predictors of lymph node metastasis.

Receptor discordance after nipple-sparing mastectomy.

Background: Recent studies have shown that receptor status of breast cancer change between primary tumor and recurrence, which may influence treatment strategy and prognosis, but there are few reports on receptor discordance between primary tumors and local recurrence (LR) after nipple-sparing mastectomy (NSM).

Patients And Methods: We collected 74 patients who had LR after NSM for newly diagnosed stages 0 to 3 breast cancer between 2008 and 2016 at 14 institutions. We classified into 4 subtypes based on hormone receptor (HR) and human epidermal growth factor receptor 2 (HER2).

Surgical risks and care trends: A cross sectional study of people experiencing homelessness presenting at a free clinic care in Miami-Dade County.

Background: The effects of housing insecurity on surgical care are under researched and largely unknown. Thus far, studies on surgery outcomes of people experiencing homelessness either focus on shelter-based patients or do not differentiate whether patients are sheltered or unsheltered, despite significant differences in care needs and health risks. Herein we provide the first report on surgical care trends of people experiencing unsheltered homelessness.
