RGD-Based Fluorescence to Assess Placental Angiogenesis.

Methods Mol Biol

November 2023

Institut National de la Santé et de la Recherche Médicale, Inserm U1292, Biosanté, Grenoble, France.

Article Synopsis
  • Normal fetal growth and placental development require active blood vessel formation (angiogenesis) at the mother-baby interface during pregnancy.
  • Researchers have developed a new, noninvasive method to measure placental blood vessel growth in pregnant mice using a fluorescent molecule, Angiostamp700, that targets specific proteins found in developing blood vessels.
  • This method allows for the quantification of angiogenic activity and provides insights into pregnancy outcomes without harming the mother or fetus.

Background: European national disparities in the integration of data linkage (ie, being able to match patient data between databases) into routine public health activities were recently highlighted. In France, the claims database covers almost the whole population from birth to death, offering a great research potential for data linkage. As the use of a common unique identifier to directly link personal data is often limited, linkage with a set of indirect key identifiers has been developed, which is associated with the linkage quality challenge to minimize errors in linked data.

NLRP7 Enhances Choriocarcinoma Cell Survival and Camouflage in an Inflammasome Independent Pathway.

Cells

March 2023

Institut National de la Santé et de la Recherche Médicale U1292, Biologie et Biotechnologie pour la Santé, 38043 Grenoble, France.

Article Synopsis
  • Gestational choriocarcinoma (GC) is a serious tumor connected to hydatidiform moles, with NLRP7 being a key gene linked to its development and immune response.
  • *Research shows that NLRP7 can operate through different pathways, significantly influencing cancer cell survival and aggressive traits in tumor cells compared to non-tumor cells.
  • *Finding that NLRP7 plays a crucial role in GC growth suggests it could be a valuable target for new treatment strategies for resistant patients.

The purpose of immune checkpoint inhibitor (ICI)-based therapies is to help the patient's immune system to combat tumors by restoring the immune response mediated by CD8+ cytotoxic T cells. Despite impressive clinical responses, most patients do not respond to ICIs. Therapeutic vaccines with autologous professional antigen-presenting cells, including dendritic cells, do not show yet significant clinical benefit.

Article Synopsis
  • Optimal management of community-acquired intra-abdominal infections (IAI) involves quick surgical intervention and proper antibiotic treatment, with a focus on how timing affects patient outcomes.
  • Conducted across 13 teaching hospitals in France with 205 adult patients, the study measured factors like hospital stay length and mortality rates related to treatment timings.
  • Key findings indicated that delays in surgical source control, higher severity scores, and older age significantly influenced both longer hospital stays and increased risk of 28-day mortality.

Article Synopsis
  • Fetal growth restriction (FGR) is linked to placental insufficiency and inflammation, with poorly understood mechanisms involving inflammasomes.
  • A study analyzed inflammasome gene expression in placental tissues from FGR and control pregnancies, revealing increased expression of NLRP3 and specific caspases and decreased IL-10 in FGR cases.
  • Experiments showed that LPS-induced inflammation raised NLRP3 levels in trophoblast models but could be mitigated by targeting NLRP3 with siRNA, suggesting its significant role in inflammation-related trophoblast dysfunction contributing to FGR.

Role of NLRP7 in Normal and Malignant Trophoblast Cells.

Biomedicines

January 2022

Institut National de la Santé et de la Recherche Médicale U1292, Biologie et Biotechnologie pour la Santé, 38054 Grenoble, France.

Article Synopsis
  • Gestational choriocarcinoma (CC) is a serious type of cancer linked to abnormal pregnancies, often leading to metastasis and maternal mortality.
  • Recent research indicates a connection between recurrent hydatidiform moles and mutations in the NLRP7 gene, which is involved in immune responses.
  • NLRP7 is found to be overexpressed in CC cells, promoting immune tolerance and affecting cell behavior, which may contribute to both normal placentation and the aggressiveness of choriocarcinoma.

Biomedicines

October 2021

French Center for Trophoblastic Diseases, University Hospital Lyon Sud, 165 Chemin du Grand Revoyet, 69495 Pierre Bénite, France.

Article Synopsis
  • The human placenta exhibits some characteristics similar to tumors, such as rapid growth and immune evasion, but the transition from benign to malignant conditions is not well understood.
  • A study using a 730-gene panel discovered 33 genes that differed between hydatidiform moles and postmolar choriocarcinoma, highlighting the dysregulation of the TGF-β pathway.
  • The findings suggest that the TGF-β pathway plays a significant role in placental cancer progression, and further research could explore its potential as a biomarker and treatment target.

Background: Optimal management of severe trauma patients with active hemorrhage relies on adequate initial resuscitation. Early administration of coagulation factors improves post-traumatic coagulation disorders, and four-factor prothrombin complex concentrate (PCC) might be useful in this context. Our main hypothesis is that four-factor PCC in addition to a massive transfusion protocol decreases blood product consumption at day 1 in severe trauma patients with major bleeding.

MALDI-TOF MS in a Medical Mycology Laboratory: On Stage and Backstage.

Microorganisms

June 2021

Translational Innovation in Medicine and Complexity, Centre National de la Recherche Scientifique, Centre Hospitalo-Universitaire Grenoble Alpes, Grenoble Alpes University, 38000 Grenoble, France.

The implementation of MALDI-TOF MS in medical microbiology laboratories has revolutionized practices and significantly reduced turnaround times of identification processes. However, although bacteriology quickly benefited from the contributions of this technique, adjustments were necessary to accommodate the specific characteristics of fungi. MALDI-TOF MS is now an indispensable tool in clinical mycology laboratories, both for the identification of yeasts and filamentous fungi, and other innovative uses are gradually emerging.

Article Synopsis
  • * Researchers employed clinical analysis of placentas and sera, in vitro studies on tumor growth, and in vivo mouse models to study NLRP7's impact on CC.
  • * Findings revealed that NLRP7 promotes tumor cell proliferation and organization, while its absence in pregnant mice led to stronger maternal immune responses and reduced tumor growth and metastasis, highlighting its role in creating an immunosuppressive environment that aids CC progression.

Older adults, especially men and/or those with diabetes, hypertension, and/or obesity, are prone to severe COVID-19. In some countries, older adults, particularly those residing in nursing homes, have been prioritized to receive COVID-19 vaccines due to high risk of death. In very rare instances, the COVID-19 vaccines can induce anaphylaxis, and the management of anaphylaxis in older people should be considered carefully.

COVID-19 vaccines: Frequently asked questions and updated answers.

June 2021

Service des maladies infectieuses, centre hospitalo-universitaire Grenoble Alpes, Grenoble, France, CIC 1406 Inserm, Grenoble, France.

At the end of December 2019, China notified the World Health Organization about a viral pneumonia epidemic soon to be named COVID-19, of which the infectious agent, SARS-CoV-2, was rapidly identified. Less than one year later, published phase 3 clinical trials underlined the effectiveness of vaccines utilizing hitherto unusual technology consisting in injection of the messenger RNA (m-RNA) of a viral protein. In the meantime, numerous clinical trials had failed to identify a maximally effective antiviral treatment, and mass vaccination came to be considered as the strategy most likely to put an end to the pandemic.

Background: Since 2009, numerous tools have been developed to detect structural variants using short read technologies. Insertions >50 bp are one of the hardest type to discover and are drastically underrepresented in gold standard variant callsets. The advent of long read technologies has completely changed the situation.
