Advanced reconstructive techniques following orbital exenteration: The role of LCFA free flaps.

Background: Orbital exenteration is a severe and disabling surgical procedure that involves the removal of all orbital contents. Effective reconstruction is crucial to managing the resulting defects. This study aims to propose a reconstructive algorithm utilizing free flaps derived from the lateral circumflex femoral artery (LCFA) system for orbital exenteration defects, based on our clinical experience.

Ectopic olfactory neuroblastoma is associated with increased frequency of syndrome of inappropriate antidiuretic hormone secretion and reduced disease control: Case series with systematic review and pooled analysis.

Introduction: Olfactory neuroblastoma (ONB) is a rare malignant tumor originating from the olfactory neuroepithelium, typically within the sinonasal cavity. Cases of ONB originating outside of the olfactory cleft area are extremely rare and are referred to as "ectopic" (eONB), in contrast to "orthotopic" tumors (oONB). ONB has been associated with paraneoplastic syndromes (PNSs), including the syndrome of inappropriate antidiuretic hormone secretion (SIADH).

Probabilistic weather forecasting with machine learning.

Weather forecasts are fundamentally uncertain, so predicting the range of probable weather scenarios is crucial for important decisions, from warning the public about hazardous weather to planning renewable energy use. Traditionally, weather forecasts have been based on numerical weather prediction (NWP), which relies on physics-based simulations of the atmosphere. Recent advances in machine learning (ML)-based weather prediction (MLWP) have produced ML-based models with less forecast error than single NWP simulations.

First evidence of microplastic ingestion by the European grayling, Thymallus thymallus, in sub-Arctic regions: Insights on plastic pollution and preliminary risk assessment in the Teno River (Finland).

Marine litter pollution affects even remote environments such as the Arctic regions and their biodiversity. However, due to the inaccessibility and difficulty of regular observations in these environments, further studies are needed to fill the knowledge gaps. In this regard, the present investigation provides new insights on microplastic contamination levels in Arctic riverfish by analyzing, for the first time, plastic ingestion by the European grayling Thymallus thymallus from the Teno River (northern Finland), an important fishery resource and vulnerable species; and performing a preliminary ecological risk assessment of microplastics in the Finnish river using the European grayling.
