Could cleaved embryo morphology and morphokinetics be associated with prenatal and neonatal outcomes?

Purpose: To evaluate if morphology and morphokinetics of cleaved embryos affect prenatal and perinatal outcomes.

Methods: This retrospective cohort study included 734 single fresh embryo transfer (SET) from ICSI from January 2014 to December 2020 at the Dijon University Hospital. Using time-lapse technology, embryos were defined as TOP or non-TOP according to morphological/morphokinetic criteria.

Major role of dolutegravir in the emergence of the S147G integrase resistance mutation.

Background: The S147G mutation is associated with high-level resistance to the integrase strand transfer inhibitor (INSTI) elvitegravir. In several poorly documented cases, it was also selected in patients on dolutegravir. Given the widespread use of dolutegravir, further studies of S147G are required.

Weak non-linearities of amorphous polymer under creep in the vicinity of the glass transition.

The creep behavior of an amorphous poly(etherimide) polymer is investigated in the vicinity of its glass transition in a weakly non linear regime where the acceleration of the creep response is driven by local configurational rearrangements. From the time shifts of the creep compliance curves under stresses from 1 to 15 MPa and in the temperature range between and , where is the glass transition temperature, we determine a macroscopic acceleration factor. The macroscopic acceleration is shown to vary as temperature with , where is the macroscopic stress and Y is a decreasing function of compliance.

Resting-State Cortico-Cerebellar Connectivity Correlates with Post-Stroke Motor Recovery - A Prospective Functional MRI Study.

Cerebellar functional and structural connectivity are likely related to motor function after stroke. Less is known about motor recovery, which is defined as a gain of function between two time points, and about the involvement of the cerebellum. Fifteen patients who were hospitalized between 2018 and 2020 for a first cerebral ischemic event with persistent upper limb deficits were assessed by resting-state functional MRI (rsfMRI) and clinical motor score measurements at 3, 9 and 15 weeks after stroke.

Single-stage surgical repair of a pre-coarctation aortic arch aneurysm and arteria lusoria.

Managing an adult patient with aortic coarctation and associated anomalies presents a significant surgical challenge. We present a case of an adult male with aortic coarctation, pre-coarctation distal arch 7-cm aneurysm involving the origin of the left subclavian artery, and aberrant (lusoria) right subclavian artery. He was managed with one surgical approach, consisting of right carotid-subclavian bypass, exclusion of the right subclavian artery, proximal descending aortic replacement and reinsertion of left subclavian artery, using partial cardiopulmonary bypass.

Mechanism of syncope: role of ambulatory blood pressure monitoring and cardiovascular autonomic function assessment.

Background And Aims: Identifying the haemodynamic mechanism of autonomic syncope is the essential pre-requisite for effective and personalized therapy aimed at preventing recurrences. The present study assessed the diagnostic efficacy of a two-step assessment.

Methods: Multicentre prospective, cross-sectional, observational study.

Major Depressive Disorder and Driving Behavior Among Older Adults.

Importance: Depression and antidepressant use are independently associated with crash risk among older drivers. However, it is unclear what factors impact daily driving that increase safety risk for drivers with depression.

Objective: To examine differences in naturalistic driving behavior and safety between older adults with and without major depressive disorder (MDD).

Odronextamab monotherapy in R/R DLBCL after progression with CAR T-cell therapy: Primary analysis of the ELM-1 study.

Patients with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL) progressing after chimeric antigen receptor T-cell therapy (CAR T) have dismal outcomes. The prespecified post-CAR T expansion cohort of the ELM-1 study investigated the efficacy and safety of odronextamab, a CD20×CD3 bispecific antibody, in patients with disease progression after CAR T. Sixty patients received IV odronextamab weekly for 4 cycles followed by maintenance until progression.

Genetic subtypes of B-cell acute lymphoblastic leukemia in adults.

B-cell acute lymphoblastic leukemia (B-ALL) is a rare malignancy in adults with outcomes remaining poor, especially compared to children. Over the past two decades, extensive whole-genome studies have identified numerous genetic alterations driving leukemia, leading to the recognition of more than 20 distinct subtypes which are closely associated with treatment response and prognosis. In pediatric B-ALL, large correlation studies have made genetic classification a central component of risk-adapted treatment strategies.

Exploring the Tomato Root Protein Network Exploited by Core Type 3 Effectors from the Species Complex.

Proteomics has become a powerful approach for the identification and characterization of type III effectors (T3Es). Members of the species complex (RSSC) deploy T3Es to manipulate host cells and to promote root infection of, among others, a wide range of solanaceous plants such as tomato, potato, and tobacco. Here, we used TurboID-mediated proximity labeling (PL) in tomato hairy root cultures to explore the proxeomes of the core RSSC T3Es RipU, RipD, and RipB.

Conservation benefits of a large marine protected area network that spans multiple ecosystems.

Marine protected areas (MPAs) are widely implemented tools for long-term ocean conservation and resource management. Assessments of MPA performance have largely focused on specific ecosystems individually and have rarely evaluated performance across multiple ecosystems either in an individual MPA or across an MPA network. We evaluated the conservation performance of 59 MPAs in California's large MPA network, which encompasses 4 primary ecosystems (surf zone, kelp forest, shallow reef, deep reef) and 4 bioregions, and identified MPA attributes that best explain performance.

Biomarkers.

Background: Speech abnormalities are increasingly recognized as a manifestation of cognitive deficits in Alzheimer's disease (AD) and its preclinical and prodromal stages. Here, we investigated whether MRI measures of brain atrophy, specifically in the basal forebrain and cortical language areas, can predict cognitive decline and speech difficulties in older adults within the AD spectrum.

Method: The ongoing Prospect-AD study aims to develop an algorithm to automatically identify speech biomarkers in individuals with early signs of AD.

Biomarkers.

Background: Spectral power of slow rhythms in resting-state EEG increases along Alzheimer's disease (AD) continuum. Besides, recent studies have revealed 1) the importance of analyzing the aperiodic component of an EEG power spectrum and 2) the intrusions of sleep-like slow waves identifiable in wake EEG of animals and young adults. Importantly, the occurrence of these wake slow waves is known i) to increase after sleep deprivation, ii) to be associated with markers of sleepiness, and iii) to predict behavioral errors at different tasks.

Biomarkers.

Background: Alzheimer's disease (AD) is a complex disorder with a strong genetic component, yet many genetic risk factors remain unknown. Integrating genome-wide association studies (GWAS) and high-throughput proteomic platforms is a useful strategy to evaluate protein quantitative trait loci (pQTLs) and to detect candidate genes and pathways involved in AD. Due to the novelty of these techniques, the identification of reliable protein measures through a comprehensive quality control is mandatory.

Biomarkers.

Background: Increasing evidence supports the use of plasma biomarkers of amyloid, tau, neurodegeneration and neuroinflammation for diagnosis of dementia. However, their performance for positive and differential diagnosis of dementia with Lewy bodies (DLB) in clinical settings is still uncertain.

Method: We conducted a retrospective biomarker study in two tertiary memory centers, Paris Lariboisière and CM2RR Strasbourg, France, enrolling patients with DLB (n=104), Alzheimer's disease (AD, n=76) and neurological controls (NC, n=27).

Biomarkers.

Background: Brain MRI segmentation is required for quantitative PET analysis, in order to derive regional uptake and calculate uptake ratio relative to reference regions. FreeSurfer has been a popular method but is being supplanted by faster and more robust AI-driven methods. The objective of this work is to confirm that the use of Clario's novel AI segmentation method, whose impact was assessed towards various MRI endpoints, is also valid in the context of PET quantification.

Biomarkers.

Background: Education has been associated with reserve mechanisms and lower dementia risk, but the literature shows inconsistent results on the association between education and brain outcomes across the lifespan. Considering that both dementia risk and education are likely to differ between sexes, our study aims at understanding the association between education and brain outcomes across the lifespan and whether it differs by sex.

Method: In 207 healthy individuals (110women) aged 19-84 years old (47.

Biomarkers.

Background: Sleep disturbances have been identified as a risk factor for developing dementia. The hypothalamus is involved in sleep regulation and may be affected early by neurodegeneration. Our aim was to investigate the relationship between subjective sleep and hypothalamic structure in adults at higher risk of developing dementia.

Biomarkers.

White matter hyperintensities (WMH) are highly prevalent in aging and Alzheimer's disease (AD) and typically attributed to vascular damage and cerebral small vessel disease. Yet, several lines of evidence from the literature emphasize the heterogeneity in the mechanisms leading to WMH, notably in AD, suggesting that WMH may be partly attributable to AD. Thus, firstly, neuropathological studies demonstrate heterogeneity in WMH histology, with indications of a link between tau pathology, Wallerian degeneration, and WMH severity.

A phase I clinical trial of intrahepatic artery delivery of TG6002 in combination with oral 5-fluorocytosine in patients with liver-dominant metastatic colorectal cancer.

Background: Effective treatment for patients with metastatic cancer is limited, particularly for colorectal cancer patients with metastatic liver lesions (mCRC), where accessibility to numerous tumours is essential for favourable clinical outcomes. Oncolytic viruses (OVs) selectively replicate in cancer cells; however, direct targeting of inaccessible lesions is limited when using conventional intravenous or intratumoural administration routes.

Methods: We conducted a multi-centre, dose-escalation, phase I study of vaccinia virus, TG6002, via intrahepatic artery (IHA) delivery in combination with the oral pro-drug 5-fluorocytosine to fifteen mCRC patients.

Biomarkers.

Background: Neuropsychiatric symptoms (NPS), including depression and circadian rhythm disruptions, are early non-cognitive markers along the Alzheimer's Disease (AD) continuum. These pathological states are thought to resemble AD pathogenesis, both of which are characterized by a marked decline in adult hippocampal neurogenesis.

Method: 96 elderly participants divided into three groups based on the global depression scale, neuropsychiatric inventory, clinical dementia rating, and mini-mental status examination.
