Relationship between muscular mass, inflammatory status, tumor metabolic activity and oral intake in head and neck cancer at the outset of management.

Background And Aims: Patients with head and neck cancer (HNC) are often malnourished with a low muscular mass at the outset of management. This is thought to be mainly due to poor nutritional intake. The aim of this study was to assess the correlation between tumor metabolic activity, inflammatory status and body composition in HNC patients.

Modifiable risk factors for culture positivity after primary Latarjet procedure. Should we change any practice?

Background: The prevalence of positive cultures in primarily operated shoulders represents a growing concern. Previous studies have documented high rates of culture positivity in primary prosthetic shoulder surgery, yet the Latarjet procedure has not been specifically explored in this context. The aim of this study was to identify the rate of culture positivity in patients treated with a primary Latarjet procedure, and to identify risk factors for culture positivity.

Latest clinical frontiers related to autism diagnostic strategies.

The diagnosis of autism is currently based on the developmental history, direct observation of behavior, and reported symptoms, supplemented by rating scales/interviews/structured observational evaluations-which is influenced by the clinician's knowledge and experience-with no established diagnostic biomarkers. A growing body of research has been conducted over the past decades to improve diagnostic accuracy. Here, we provide an overview of the current diagnostic assessment process as well as of recent and ongoing developments to support diagnosis in terms of genetic evaluation, telemedicine, digital technologies, use of machine learning/artificial intelligence, and research on candidate diagnostic biomarkers.

Extracellular volume expansion drives vertebrate axis elongation.

The vertebrate bauplan is primarily established via the formation of embryonic tissues in a head-to-tail progression. The mechanics of this elongation, which requires the presomitic mesoderm (PSM), remain poorly understood. Here, we find that avian PSM explants can elongate autonomously when physically confined in vitro, producing a pushing force promoting posterior elongation of the embryo.

On-site recurrence risk after parenchymal R1 liver resection for colorectal metastases.

Background: Histologic microscopic positive resection margin is a debated prognostic factor in patients resected for colorectal liver metastases. This study aimed to assess whether patients with R1 resection experience recurrence at the site of the resection (on-site recurrence) and to identify predictive factors for recurrence profiles in patients with R1 margins after resection of colorectal liver metastases.

Methods: All surgical colorectal liver metastasis resection cases with R1 parenchymal margin from September 2014 to March 2020 in our center were retrospectively included.

Artificial intelligence for diagnosis and predictive biomarkers in Non-Small cell lung cancer Patients: New promises but also new hurdles for the pathologist.

The rapid development of artificial intelligence (AI) based tools in pathology laboratories has brought forward unlimited opportunities for pathologists. Promising AI applications used for accomplishing diagnostic, prognostic and predictive tasks are being developed at a high pace. This is notably true in thoracic oncology, given the significant and rapid therapeutic progress made recently for lung cancer patients.

Mucinous ovarian carcinoma: Impact of ovarian stimulation, hormonal contraception, and hormone replacement therapy.

Unlike high-grade serous carcinoma (HGSC), which mainly affects postmenopausal women, mucinous ovarian carcinoma (MOC) affects younger patients, with a median age at diagnosis of 53 years, and is rare among premenopausal women. After they receive anticancer treatment, these women encounter specific issues involving fertility preservation (FP) and/or pregnancy, which potentially require assisted reproductive technology (ART) as well as the prescription of hormonal contraception (HC) or hormone replacement therapy (HRT). We reviewed the available literature in PubMed/Medline concerning the risks of the development of ovarian cancer (OC), including MOC, associated with ART, HC and HRT, and literature on the impact of ovarian stimulation in the context of FP and/or ART, HC and HRT in women previously treated for OC, including MOC.

Safety and efficacy of tamoxifen in non-ambulant patients with Duchenne muscular dystrophy: a multicentre, randomised, double-blind, placebo-controlled, phase 3 trial (TAMDMD Group B).

Most patients with Duchenne muscular dystrophy (DMD) are non-ambulant. Preserving proximal motor function is crucial, rarely studied. Tamoxifen, a selective oestrogen receptor modulator, reduced signs of muscular pathology in a DMD mouse model.

Digital Representation of Patients as Medical Digital Twins: Data-Centric Viewpoint.

Precision medicine involves a paradigm shift toward personalized data-driven clinical decisions. The concept of a medical "digital twin" has recently become popular to designate digital representations of patients as a support for a wide range of data science applications. However, the concept is ambiguous when it comes to practical implementations.

Medical management pathways for Cushing's disease in pituitary tumors centers of excellence (PTCOEs).

Purpose: A recent update of consensus guidelines for the management of Cushing's disease (CD) included indications for medical therapy. However, there is limited evidence regarding their implementation in clinical practice. This study aimed to evaluate current medical therapy approaches by expert pituitary centers through an audit conducted to validate the criteria of Pituitary Tumors Centers of Excellence (PTCOEs) and provide an initial standard of medical care for CD.

Signature cytokine-associated transcriptome analysis of effector γδ T cells identifies subset-specific regulators of peripheral activation.

γδ T cells producing either interleukin-17A (γδ cells) or interferon-γ (γδ cells) are generated in the mouse thymus, but the molecular regulators of their peripheral functions are not fully characterized. Here we established an Il17a-GFP:Ifng-YFP double-reporter mouse strain to analyze at unprecedented depth the transcriptomes of pure γδ cell versus γδ cell populations from peripheral lymph nodes. Within a very high fraction of differentially expressed genes, we identify a panel of 20 new signature genes in steady-state γδ cells versus γδ cells, which we further validate in models of experimental autoimmune encephalomyelitis and cerebral malaria, respectively.

The Ronne Ice Shelf survived the last interglacial.

The fate of the West Antarctic Ice Sheet (WAIS) is the largest cause of uncertainty in long-term sea-level projections. In the last interglacial (LIG) around 125,000 years ago, data suggest that sea level was several metres higher than today, and required a significant contribution from Antarctic ice loss, with WAIS usually implicated. Antarctica and the Southern Ocean were warmer than today, by amounts comparable to those expected by 2100 under moderate to high future warming scenarios.

Convergent evidence for the temperature-dependent emergence of silicification in terrestrial plants.

Research on silicon (Si) biogeochemistry and its beneficial effects for plants has received significant attention over several decades, but the reasons for the emergence of high-Si plants remain unclear. Here, we combine experimentation, field studies and analysis of existing databases to test the role of temperature on the expression and emergence of silicification in terrestrial plants. We first show that Si is beneficial for rice under high temperature (40 °C), but harmful under low temperature (0 °C), whilst a 2 °C increase results in a 37% increase in leaf Si concentrations.

CODE-ACCORD: A Corpus of building regulatory data for rule generation towards automatic compliance checking.

Automatic Compliance Checking (ACC) within the Architecture, Engineering, and Construction (AEC) sector necessitates automating the interpretation of building regulations to achieve its full potential. Converting textual rules into machine-readable formats is challenging due to the complexities of natural language and the scarcity of resources for advanced Machine Learning (ML). Addressing these challenges, we introduce CODE-ACCORD, a dataset of 862 sentences from the building regulations of England and Finland.

Diffusion-driven transient hydrogenation in metal superhydrides at extreme conditions.

In recent years, metal hydride research has become one of the driving forces of the high-pressure community, as it is believed to hold the key to superconductivity close to ambient temperature. While numerous novel metal hydride compounds have been reported and extensively investigated for their superconducting properties, little attention has been focused on the atomic and electronic states of hydrogen, the main ingredient in these novel compounds. Here, we present combined H- and La-NMR data on lanthanum superhydrides, LaH, (x = 10.

[Total nasal reconstruction by folded forearm radial flap: Technical note].

Total nasal reconstruction represents a complex challenge, requiring restoration of all three anatomical planes while preserving respiratory function. This procedure has significant therapeutic, aesthetic, social and professional implications for patients. We share our academic experience of reconstruction using a folded microanastomosed radial forearm flap (FRFF) combined with a paramedian forehead flap, using the technique of F.

Evolution of different forearm flap designs in phalloplasty.

Phalloplasty is one of the most complex procedures in plastic surgery. The criteria for an ideal neophallus include an aesthetic and erogenous phallus that allows for sexual intercourse, with a functional neo-urethra enabling standing urination. The free forearm flap has become the gold standard for phallic reconstruction.

Contribution of rat insular cortex to stimulus-guided action.

Anticipating rewards is fundamental for decision-making. Animals often use cues to assess reward availability and to make predictions about future outcomes. The gustatory region of the insular cortex (IC), the so-called gustatory cortex, has a well-established role in the representation of predictive cues, such that IC neurons encode both a general form of outcome expectation as well as anticipatory outcome-specific knowledge.

New Artisse intrasaccular device for intracranial aneurysm treatment: short term clinical and angiographic result from the prospective registry INSPIRE-A.

Background: Intrasaccular devices have broadened treatment options for wide necked aneurysms. This study presents the preliminary experience with the Artisse 2.0 device.

Biodegradation study in FBS media of polycaprolactone patch as a potential prenatal treatment for myelomeningocele.

Myelomeningocele (MMC) is a congenital defect of the spine characterized by meningeal and spinal cord protrusion through open vertebral archs, and its exposure to the amniotic fluid. Given that the progression of neuronal loss begins early in fetal life, an early coverage of the defect is required to improve the neurological outcomes. Several studies have proposed patches as an alternative to full surgical repair, to achieve an early protection of the spine and possibly reduce the rate of complications of current prenatal surgical procedures.
