Evaluation of a Decentralized Donor-Derived Cell-Free DNA Assay for Kidney Allograft Rejection Monitoring.

Donor-derived cell-free DNA (dd-cfDNA) is an emerging non-invasive biomarker for allograft injury detection. This study aimed to evaluate a new, decentralized dd-cfDNA testing kit against a centralized dd-cfDNA testing service broadly utilized in the United States. Kidney transplant recipients with decentralized and centralized dd-cfDNA measurements and concomitant kidney allograft biopsies were included in the study.

Immune response after pig-to-human kidney xenotransplantation: a multimodal phenotyping study.

Background: Cross-species immunological incompatibilities have hampered pig-to-human xenotransplantation, but porcine genome engineering recently enabled the first successful experiments. However, little is known about the immune response after the transplantation of pig kidneys to human recipients. We aimed to precisely characterise the early immune responses to the xenotransplantation using a multimodal deep phenotyping approach.

To what extent do people living with HIV, people on pre-exposure prophylaxis, doctors and pharmacists endorse 90-day dispensing of antiretroviral therapy in France?

Justification: The WHO 95-95-95 targets for 2030 do not imply that people living with HIV (PLHIV) achieve a good quality of life. The current 30-day dispensing interval for antiretroviral (ART) burdens the healthcare system. Lengthening dispensing intervals could alleviate this burden as well as enhance patient well-being.

FIBER-ML, an Open-Source Supervised Machine Learning Tool for Quantification of Fibrosis in Tissue Sections.

Pathologic fibrosis is a major hallmark of tissue insult in many chronic diseases. Although the amount of fibrosis is recognized as a direct indicator of the extent of disease, there is no consentaneous method for its quantification in tissue sections. This study tested FIBER-ML, a semi-automated, open-source freeware that uses a machine-learning approach to quantify fibrosis automatically after a short user-controlled learning phase.

The BMS-LM ontology for biomedical data reporting throughout the lifecycle of a research study: From data model to ontology.

Biomedical research data reuse and sharing is essential for fostering research progress. To this aim, data producers need to master data management and reporting through standard and rich metadata, as encouraged by open data initiatives such as the FAIR (Findable, Accessible, Interoperable, Reusable) guidelines. This helps data re-users to understand and reuse the shared data with confidence.

Impact of the COVID-19 pandemic on publication dynamics and non-COVID-19 research production.

Background: The COVID-19 pandemic has severely affected health systems and medical research worldwide but its impact on the global publication dynamics and non-COVID-19 research has not been measured. We hypothesized that the COVID-19 pandemic may have impacted the scientific production of non-COVID-19 research.

Methods: We conducted a comprehensive meta-research on studies (original articles, research letters and case reports) published between 01/01/2019 and 01/01/2021 in 10 high-impact medical and infectious disease journals (New England Journal of Medicine, Lancet, Journal of the American Medical Association, Nature Medicine, British Medical Journal, Annals of Internal Medicine, Lancet Global Health, Lancet Public Health, Lancet Infectious Disease and Clinical Infectious Disease).

Increase in lamin B1 promotes telomere instability by disrupting the shelterin complex in human cells.

Telomere maintenance is essential to preserve genomic stability and involves telomere-specific proteins, DNA replication and repair proteins. Lamins are key components of the nuclear envelope and play numerous roles, including maintenance of the nuclear integrity, regulation of transcription, and DNA replication. Elevated levels of lamin B1, one of the major lamins, have been observed in some human pathologies and several cancers.

Sunitinib-induced cardiac hypertrophy and the endothelin axis.

Anti-angiogenics drugs in clinical use for cancer treatment induce cardiotoxic side effects. The endothelin axis is involved in hypertension and cardiac remodelling, and addition of an endothelin receptor antagonist to the anti-angiogenic sunitinib was shown to reduce cardiotoxicity of sunitinib in mice. Here, we explored further the antidote effect of the endothelin receptor antagonist macitentan in sunitinib-treated animals on cardiac remodeling.

Pharmacist's role in HIV care in France. Implication for clinical improvement of people living with HIV worldwide.

In France, antiretroviral (ARV) treatment can be dispensed by hospital and/or community pharmacies. Since January 2016, an online patient medication file can be used to optimize dispensing, but medication interviews have not yet been incorporated into this system. To understand both people living with HIV (PLHIV) and their pharmacists' habits and expectations of patient medication file and interviews, two consecutive national surveys were organized.

This article presents the results of a qualitative research on practices of dispensing antiretroviral medication concerning requests for greater than one month, for departure abroad. In spite of a strict regulation, a cartography shows a heterogeneity of its application leading to a great diversity of dispensing practices. This qualitative research with 22 pharmacies across the territory reveals relational and regulatory logics that contribute to this non-uniformity of practices.

[Training and conditions improving the integration of patients in the co-facilitation of collective sessions of therapeutic education].

Unlabelled: Purpose of research: The purpose of this research was to promote the involvement and intervention of patient-partners (PPs) in collective sessions of therapeutic patient education (TPE), including training and support for the implementation of these sessions, in co-facilitation with a health professional (HP). Therefore, the matter was to co-construct a training model, to experiment with its implementation and to define favorable conditions for this collaboration.

Methods: Collaborative research oriented by the design, led by a steering committee representative of different categories of stakeholders, which has been spread over 2 years, in Paris area and Montpellier, in 4 phases: 1/ exploration (bibliographic review and investigation); 2/ recruitment of PPs affected by different pathologies; 3/ implementation and evaluation of PPs training in inter-pathology; 4/ implementation and evaluation of co-facilitated group sessions.

Concurrent imaging of vascularization and metabolism in a mouse model of paraganglioma under anti-angiogenic treatment.

: Deregulation of metabolism and induction of vascularization are major hallmarks of cancer. Using a new multimodal preclinical imaging instrument, we explored a sequence of events leading to sunitinib-induced resistance in a murine model of paraganglioma (PGL) invalidated for the expression of succinate dehydrogenase subunit B (). : Two groups of tumors bearing mice were treated with sunitinib (6 weeks) or vehicle (3 weeks).

Long-Term Evaluation of Biliary Reflux on Esogastric Mucosae after One-Anastomosis Gastric Bypass and Esojejunostomy in Rats.

Background: One-anastomosis gastric bypass/mini-gastric bypass (OAGB/MGB) remains controversial because it may cause chronic biliary reflux (BR). The risk of developing esogastric cancer due to BR after OAGB/MGB is based on the results of experimental rat studies using esojejunostomy (EJ). The aim of this study was to analyze the potential long-term consequences of BR on the esogastric mucosae in OAGB/MGB-operated rats and to compare these results to those from the use of EJ.

Budget impact of antiretroviral therapy in a French clinic cohort.

Objectives: In this study, we first assessed costs associated with the use of antiretroviral therapy (ART) in an infectious diseases University Hospital Clinic; second, we evaluated characteristics associated with these costs and finally simulated the impact on the overall ART budget of switching first-line and second-line regimens to less-costly regimens (as effective and well tolerated).

Design: Cohort analysis including persons living with HIV (PLHIV) aged at least 18 years on ART to estimate ART costs during 2014.

Methods: The current study was conducted in the Bichat-Claude Bernard University Hospital Clinic in Paris, France, where 4501 PLHIV consulted in 2014.

Ballistic effects on the copper precipitation and re-dissolution kinetics in an ion irradiated and thermally annealed Fe-Cu alloy.

Studies of solute precipitation and precipitate phase stability in nuclear structural materials under concurrent irradiation and heat often lead to contradictory results due to the complex nature of the phenomena which is far from well understood. Here, we present a comprehensive atomistically based continuum model for the copper precipitation and re-dissolution kinetics in an ion irradiated and thermally annealed Fe-0.78 at.

[Galenic forms for oral medication].

Galenic science is interested in the art and the way of formulating an active principle with an excipient in order for it to be administered to the patient. The pharmaceutical forms envisage different administration routes, including by mouth. Nurses need to handle and sometimes modify the pharmaceutical form of a drug to make it easier for the patient to take.

Phase II study of cetuximab as first-line single-drug therapy in patients with unresectable squamous cell carcinoma of the skin.

Purpose: To evaluate the efficacy and safety of cetuximab, a monoclonal antibody that inhibits the epidermal growth factor receptor (EGFR), as a first-line monotherapy in patients with unresectable squamous cell carcinoma of the skin (SCCS).

Patients And Methods: Thirty-six patients received cetuximab (initial dose of 400 mg/m(2) followed by subsequent weekly doses of 250 mg/m(2)) for at least 6 weeks with a 48-week follow-up. The primary end point was the disease control rate (DCR) at 6 weeks (according to Response Evaluation Criteria in Solid Tumors [RECIST] criteria).

Lamivudine and indinavir/ritonavir maintenance therapy in highly pretreated HIV-infected patients (Vista ANRS 109).

Objective: In patients with extensive HIV resistance, one option is to delay salvage therapy until new drugs become available. We hypothesized that this delay period could be based on a simplified treatment, which would reduce drug toxicity, stabilize resistance, and prevent resurgence of wild-type virus.

Methods: A prospective 24-week treatment simplification study in HIV-1-infected patients having failed several lines of antiretroviral therapy, with CD4+ T-cell counts > or = 100 cells/ml, plasma HIV RNA (viral load [VL]) > or = 4 log10 copies/ml and a resistance genotype predicting less than two active drugs.

Nevirapine or lamivudine plus stavudine and indinavir: examples of 2-class versus 3-class regimens for the treatment of human immunodeficiency virus type 1.

We compared use of a 3-class regimen (nevirapine [Nvp], stavudine [d4T], and indinavir [Idv; 1000 mg 3 times daily]) with use of a 2-class regimen (lamivudine [3TC], d4T, and Idv [800 mg 3 times daily]) for 145 patients infected with human immunodeficiency virus type 1 (HIV-1). At week 72, the plasma HIV-1 RNA level was undetectable in 52% of Nvp recipients versus 79% of 3TC recipients (P<.001).
