Prognostic impact of high-intensity lipid-lowering therapy under-prescription after acute myocardial infarction in women.

Aims: Women are less likely to receive lipid-lowering therapy (LLT) after acute myocardial infarction (AMI). We analysed whether this under-prescription currently persists and has an impact on long-term outcomes.

Methods And Results: The FAST-MI programme consists of nationwide registries including all patients admitted for AMI ≤ 48 h from onset over a 1 month period in 2005, 2010, and 2015, with long-term follow-up.

Three-Year Outcomes With Fractional Flow Reserve-Guided or Angiography-Guided Multivessel Percutaneous Coronary Intervention for Myocardial Infarction.

Background: In patients with multivessel disease with successful primary percutaneous coronary intervention for ST-segment-elevation myocardial infarction, the FLOWER-MI trial (Flow Evaluation to Guide Revascularization in Multivessel ST-Elevation Myocardial Infarction) showed that a fractional flow reserve (FFR)-guided strategy was not superior to an angiography-guided strategy for treatment of noninfarct-related artery lesions regarding the 1-year risk of death from any cause, myocardial infarction, or unplanned hospitalization leading to urgent revascularization. The extension phase of the trial was planned using the same primary outcome to determine whether a difference in outcomes would be observed with a longer follow-up.

Methods: In this multicenter trial, we randomly assigned patients with ST-segment-elevation myocardial infarction and multivessel disease with successful percutaneous coronary intervention of the infarct-related artery to receive complete revascularization guided by either FFR (n=586) or angiography (n=577).

Analysis of Ag-DP25/PET plasmonic nano-composites as a visible-light photocatalyst for wastewater treatment: Experimental/theoretical studies, and the DFT-MB degradation mechanism.

The development of polymeric-composites Agx%DP25-PET (x = 0,1,2,3) may significantly boost the potential application of Agx%DP25 (x = 0,1,2,3) photocatalytic powders. Producing large-scale nano-composites with hybrid-surfaces, that are also flexible materials and easy to employ in a variety of environments. A set of photocatalytic nan-composites embedded with the polymeric binder poly (acrylonitrile-co-butadiene)-dicarboxy terminated (C7H9N) were performed and evaluated for wastewater treatment applications.

Rationale and design of the direct oral anticoagulants for prevention of left ventricular thrombus after anterior acute myocardial infarction (APERITIF) trial.

Background: Anterior acute myocardial infarction (AMI) is associated with an increased risk of left ventricular (LV) thrombus formation. We hypothesized that adding low-dose oral rivaroxaban to the usual antiplatelet regimen would reduce the risk of LV thrombus in patients with large AMI.

Study Design: APERITIF is an investigator-initiated, multicenter randomized open-label, blinded end-point (PROBE) trial, nested in the ongoing "FRENCHIE" registry, a French multicenter prospective observational study, in which all consecutive patients admitted within 48 hours of symptom onset in a cardiac Intensive Care Unit (ICU) for AMI are included (NCT04050956).

The biological sample collection of the OFSEP French MS registry: An essential tool dedicated to researchers.

Today's medicine strives to be personalized, preventive, predictive and participatory. This implies to have access to multimodal data to better characterize patients groups and to combine clinical and imaging data with high-quality biological samples. Collecting such data is one of the objectives of the Observatoire français de la sclérose en plaques (OFSEP), the French MS registry.

Very long-term outcomes after acute myocardial infarction in young men and women: Insights from the FAST-MI program.

Aims: Conflicting data exists about long-term outcomes in young women and men experiencing acute myocardial infarction (AMI).

Methods: The FAST-MI program consists of three nationwide French surveys carried out 5years apart from 2005 to 2015, including consecutive patients with AMI over a 1-month period with up to 10-year follow-up. The present analysis focused on adults≤50 yo according to their gender.

[F]DPA-714: Effect of co-medications, age, sex, BMI and TSPO polymorphism on the human plasma input function.

Purpose: We aimed to assess the effect of concomitant medication, age, sex, body mass index and 18-kDa translocator protein (TSPO) binding affinity status on the metabolism and plasma pharmacokinetics of [F]DPA-714 and their influence on the plasma input function in a large cohort of 201 subjects who underwent brain and whole-body PET imaging to investigate the role of neuroinflammation in neurological diseases.

Methods: The non-metabolized fraction of [F]DPA-714 was estimated in venous plasma of 138 patients and 63 healthy controls (HCs; including additional arterial sampling in 16 subjects) during the 90 min brain PET acquisition using a direct solid-phase extraction method. The mean fraction between 70 and 90 min post-injection ([F]DPA-714) and corresponding normalized plasma concentration (SUV) were correlated with all factors using a multiple linear regression model.

Multi-population genome-wide association study implicates immune and non-immune factors in pediatric steroid-sensitive nephrotic syndrome.

Pediatric steroid-sensitive nephrotic syndrome (pSSNS) is the most common childhood glomerular disease. Previous genome-wide association studies (GWAS) identified a risk locus in the HLA Class II region and three additional independent risk loci. But the genetic architecture of pSSNS, and its genetically driven pathobiology, is largely unknown.

Therapies for obsessive-compulsive disorder: Current state of the art and perspectives for approaching treatment-resistant patients.

Even though obsessive compulsive disorder (OCD) is one of the ten most disabling diseases according to the WHO, only 30-40% of patients suffering from OCD seek specialized treatment. The currently available psychotherapeutic and pharmacological approaches, when properly applied, prove ineffective in about 10% of cases. The use of neuromodulation techniques, especially Deep Brain Stimulation, is highly promising for these clinical pictures and knowledge in this domain is constantly evolving.

Investigating the Long-term Effect of Pregnancy on the Course of Multiple Sclerosis Using Causal Inference.

Background And Objectives: The question of the long-term safety of pregnancy is a major concern in patients with multiple sclerosis (MS), but its study is biased by reverse causation (women with higher disability are less likely to experience pregnancy). Using a causal inference approach, we aimed to estimate the unbiased long-term effects of pregnancy on disability and relapse risk in patients with MS and secondarily the short-term effects (during the perpartum and postpartum years) and delayed effects (occurring beyond 1 year after delivery).

Methods: We conducted an observational cohort study with data from patients with MS followed in the Observatoire Français de la Sclérose en Plaques registry between 1990 and 2020.

High Dose Pharmaceutical Grade Biotin (MD1003) Accelerates Differentiation of Murine and Grafted Human Oligodendrocyte Progenitor Cells In Vivo.

Accumulating evidences suggest a strong correlation between metabolic changes and neurodegeneration in CNS demyelinating diseases such as multiple sclerosis (MS). Biotin, an essential cofactor for five carboxylases, is expressed by oligodendrocytes and involved in fatty acid synthesis and energy production. The metabolic effect of biotin or high-dose-biotin (MD1003) has been reported on rodent oligodendrocytes in vitro, and in neurodegenerative or demyelinating animal models.

Highly asymmetrical distribution of muscle wasting correlates to the heteroplasmy in a patient carrying a large-scale mitochondrial DNA deletion: a novel pathophysiological mechanism for explaining asymmetry in mitochondrial myopathies.

Mitochondrial diseases are a heterogeneous group of pathologies, caused by missense mutations, sporadic large-scale deletions of mitochondrial DNA (mtDNA) or mutations of nuclear maintenance genes. We report the case of a patient in whom extended muscle pathology, biochemical and genetic mtDNA analyses have proven to be essential to elucidate a unique asymmetrical myopathic presentation. From the age of 34 years on, the patient has presented with oculomotor disorders, right facial peripheral palsy and predominantly left upper limb muscle weakness and atrophy.

Chemical characterization of inks in skin reactions to tattoo.

Skin reactions are well described complications of tattooing, usually provoked by red inks. Chemical characterizations of these inks are usually based on limited subjects and techniques. This study aimed to determine the organic and inorganic composition of inks using X-ray fluorescence spectroscopy (XRF), X-ray absorption spectroscopy (XANES) and Raman spectroscopy, in a cohort of patients with cutaneous hypersensitivity reactions to tattoo.

Multimorbidity, functional impairment, and mortality in older patients stable after prior acute myocardial infarction: Insights from the TIGRIS registry.

Background: Data on the association of multimorbidity and functional impairment with cardiovascular (CV) and non-CV outcomes among older myocardial infarction (MI) patients are limited.

Hypothesis: Multimorbidity and functional impairment among older MI patients are associated with CV and non-CV mortality.

Methods: Patients aged ≥65 years, 1-3 years post-MI, and enrolled between June 2013 and Novemeber 2014 from 349 sites in 25 countries in the global TIGRIS registry were categorized by age, number of comorbidities, and presence and degree of functional impairment.

Immediate versus staged complete myocardial revascularization in patients with ST-segment elevation myocardial infarction and multivessel disease: A post hoc analysis of the randomized FLOWER-MI trial.

Background: In patients with ST-segment elevation myocardial infarction and multivessel disease, percutaneous coronary intervention for non-culprit lesions is superior to treatment of the culprit lesion alone. The optimal timing for non-infarct-related artery revascularization - immediate versus staged - has not been investigated adequately.

Aim: We aimed to assess clinical outcomes at 1 year in patients with ST-segment elevation myocardial infarction with multivessel disease using immediate versus staged non-infarct-related artery revascularization.

Time-series incubations in a coastal environment illuminates the importance of early colonizers and the complexity of bacterial biofilm dynamics on marine plastics.

The problematic of microplastics pollution in the marine environment is tightly linked to their colonization by a wide diversity of microorganisms, the so-called plastisphere. The composition of the plastisphere relies on a complex combination of multiple factors including the surrounding environment, the time of incubation along with the polymer type, making it difficult to understand how the biofilm evolves during the microplastic lifetime over the oceans. To better define bacterial community assembly processes on plastics, we performed a 5 months spatio-temporal survey of the plastisphere in an oyster farming area in the Bay of Brest (France).

The success of the bloom-forming cyanobacteria Planktothrix: Genotypes variability supports variable responses to light and temperature stress.

Cyanobacterial blooms can modify the dynamic of aquatic ecosystems and have harmful consequences for human activities. Moreover, cyanobacteria can produce a variety of cyanotoxins, including microcystins, but little is known about the role of environmental factors on the prevalence of microcystin producers in the cyanobacterial bloom dynamics. This study aimed to better understand the success of Planktothrix in various environments by unveiling the variety of strategies governing cell responses to sudden changes in light intensity and temperature.

Phage-host coevolution in natural populations.

Coevolution between bacteriophages (phages) and their bacterial hosts occurs through changes in resistance and counter-resistance mechanisms. To assess phage-host evolution in wild populations, we isolated 195 Vibrio crassostreae strains and 243 vibriophages during a 5-month time series from an oyster farm and combined these isolates with existing V. crassostreae and phage isolates.

HIRA Supports Hepatitis B Virus Minichromosome Establishment and Transcriptional Activity in Infected Hepatocytes.

Background & Aims: Upon hepatitis B virus (HBV) infection, partially double-stranded viral DNA converts into a covalently closed circular chromatinized episomal structure (cccDNA). This form represents the long-lived genomic reservoir responsible for viral persistence in the infected liver. Although the involvement of host cell DNA damage response in cccDNA formation has been established, this work investigated the yet-to-be-identified histone dynamics on cccDNA during early phases of infection in human hepatocytes.
