Ischemia-reperfusion (IR) is a leading cause of acute kidney injury (AKI), and pigs are commonly used in preclinical AKI models. However, existing models often vary in the methods used to induce ischemia, and the resulting AKI tends to be mild-to-moderate. Moreover, follow-up is often performed under volatile anesthesia, which, in contrast to total intravenous anesthesia (TIVA), can induce malignant hyperthermia and cause hemodynamic instability.

Metastatic uveal melanoma (UM) patients often initially present with limited symptoms despite a poor prognosis, complicating communication with patients and caregivers. Early Together (NCT04728113) is a randomized Phase III trial that integrates early palliative care through systematic joint visits involving the palliative care team and the medical oncologist, compared with standard oncological care, in 162 metastatic UM patients beginning systemic treatment. This collaboration aims to enhance patient functioning, improve quality of life and facilitate coping mechanisms.

The evolution of information and communication technologies has affected all fields of science, including health sciences. However, the rate of technological innovation adoption by the healthcare sector has been historically slow, compared to other industrial sectors. Innovation in computer modeling and simulation approaches has changed the landscape in biomedical applications and biomedicine, paving the way for their potential contribution in reducing, refining, and partially replacing animal and human clinical trials.

Introduction: The importance of body composition and sarcopenia is well-recognized in cancer patient outcomes and treatment tolerance, yet routine evaluations are rare due to their time-intensive nature. While CT scans provide accurate measurements, they depend on manual processes. We developed and validated a deep learning algorithm to automatically select and segment abdominal muscles [SM], visceral fat [VAT], and subcutaneous fat [SAT] on CT scans.

Article Synopsis
  • The study evaluates the prevalence and progression of malnutrition and sarcopenia in patients with metastatic breast cancer, revealing that both conditions are common and often overlap.
  • It identifies risk factors, noting that patients over 60 are more likely to experience solitary malnutrition and its combinations, but not solitary sarcopenia.
  • The findings indicate that solitary malnutrition is linked to poorer overall survival, while solitary sarcopenia and combined malnutrition/sarcopenia do not show the same association.

Dogs are the main source of animal and human cystic echinococcosis caused by the Cestode parasite Echinococcus granulosus. Dog vaccination seems to be a good strategy to control this parasitic disease. Here we present the development of a polymeric nanoparticle-based oral vaccine for dogs against Echinococcus granulosus delivered in enteric-coated capsules.

The European Society for Clinical Nutrition and Metabolism (ESPEN) guidelines, shortened in 2021, are widely used for providing the most suitable nutrition support to patients with cancer. However, there is a lack of specialized guidelines for different cancer types. In 2020, members of the French medical and surgical societies involved in digestive oncology, nutrition and supportive care developed the Thésaurus National de Cancérologie Digestive (TNCD) practice guidelines which are specific nutritional and physical activity guidelines for patients with digestive cancers.

Netrin-1 is a member of the laminin superfamily, and is known to interact with specific receptors, called dependence receptors. While upon netrin-1 binding these receptors initiate positive signaling, in absence of netrin-1, these receptors trigger apoptosis. Tumor cells can avoid apoptosis by inactivating these receptors or by gaining ligand expression.

In Silico Trials methodologies will play a growing and fundamental role in the development and de-risking of new medical devices in the future. While the regulatory pathway for Digital Patient and Personal Health Forecasting solutions is clear, it is more complex for In Silico Trials solutions, and therefore deserves a deeper analysis. In this position paper, we investigate the current state of the art towards the regulatory system for in silico trials applied to medical devices while exploring the European regulatory system toward this topic.

Malnutrition is associated with a greater risk of morbidity and mortality and lower tolerance to chemotherapy. Our purpose was to study the association between nutritional status and the efficiency and tolerance of immunotherapy in non-small cell lung cancer (NSCLC). Nutritional and oncological data were reported at 2 months (M2) and 4 months (M4) after the initiation of immunotherapy (M0).

Objectives: In managing patients with cancer in the COVID-19 era, clinical oncologists and palliative care practitioners had to face new, disrupting and complex medical situations, challenging the quality of the shared decision-making process. During the first lockdown in France, we developed an onco-palliative ethics meeting to enhance the quality of the decision-making process for patients with advanced cancer treated for COVID-19.

Methods: A least one of the institutional ethics committee members was present along with oncologists, palliative care teams, psycho-oncologists, radiologists and intensive care specialists.

Background: Team-based and timely integrated palliative care is a gold standard of care in oncology, but issues concerning its optimal organization remain. Palliative Care in Day-Hospital (PCDH) could be one of the most efficient service model of palliative care to deliver interdisciplinary and multidimensional care addressing the complex supportive care needs of patients with advanced cancer. We hypothesize that, compared to conventional outpatient palliative care, PCDH allows the clinical benefits of palliative care to be enhanced.

Canine cutaneous histiocytoma (CCH) is a noninfectious tumor that spontaneously regresses. It is suggested that this regression is due to tumor cell maturation, which is responsible for CD8 lymphocyte activation and tumor cell destruction. Nevertheless, the possible role of the immune microenvironment in tumor regression has not been investigated to date.

Within a time span of only a few months, the SARS-CoV-2 virus has managed to spread across the world. This virus can spread by close contact, which includes large droplet spray and inhalation of microscopic droplets, and by indirect contact via contaminated objects. While in most countries, supermarkets have remained open, due to the COVID-19 pandemic, authorities have ordered many other shops, restaurants, bars, music theaters and indoor sports centers to be closed.

Enterohaemorrhagic (EHEC) are bacterial pathogens responsible for life-threatening diseases in humans such as bloody diarrhoea and the hemolytic and uremic syndrome. To date, no specific therapy is available and treatments remain essentially symptomatic. In recent years, we demonstrated that nitric oxide (NO), a major mediator of the intestinal immune response, strongly represses the synthesis of the two cardinal virulence factors in EHEC, namely Shiga toxins (Stx) and the type III secretion system, suggesting NO has a great potential to protect against EHEC infection.
