Mid-regional pro-adrenomedullin: A rapid sepsis biomarker for diagnosing spontaneous bacterial peritonitis in cirrhosis.

Background: Spontaneous bacterial peritonitis (SBP) is a frequent and life-threatening complication of cirrhosis, contributing to considerable morbidity and mortality.

Methods: A cross-sectional derivation study was conducted to assess the diagnostic accuracy of two sepsis-related calcitonin peptide family biomarkers, mid-regional pro-adrenomedullin (MR-pro-ADM) and procalcitonin, in ascitic fluid for identifying bacteriologically confirmed SBP (BC-SBP). In a subsequent validation study, the diagnostic performance of the 'SBP score' was evaluated in an independent patient cohort using an absolute polymorphonuclear (PMN) leukocyte count threshold of ≥250 cells/mm as the diagnostic benchmark for diagnosing SBP.

Thalamic Deep Brain Stimulation Versus Magnetic Resonance-Guided Focused Ultrasound in Tremor Patients: A Retrospective Single-Surgeon Comparison.

Background: Bilateral deep brain stimulation (DBS) and unilateral magnetic resonance-guided focused ultrasound (MRgFUS), with potential future second-side treatment targeting the thalamic ventral intermediate nucleus (VIM), are currently the two best-established interventions for pharmaco-resistant tremors, but treatment selection is hampered by the lack of comparative evidence.

Objective: To provide the first direct within-center and within-surgeon comparison between bilateral VIM-DBS and unilateral VIM-MRgFUS, applying consistently timed and elaborated efficacy and safety assessements.

Methods: In this retrospective study, we included patients having received bilateral VIM-DBS (n = 30) or unilateral VIM-MRgFUS (n = 52) performed by one single neurosurgeon between 2014 and 2022.

Fluo-Cast-Bright: a deep learning pipeline for the non-invasive prediction of chromatin structure and developmental potential in live oocytes.

In mammalian oocytes, large-scale chromatin organization regulates transcription, nuclear architecture, and maintenance of chromosome stability in preparation for meiosis onset. Pre-ovulatory oocytes with distinct chromatin configurations exhibit profound differences in metabolic and transcriptional profiles that ultimately determine meiotic competence and developmental potential. Here, we developed a deep learning pipeline for the non-invasive prediction of chromatin structure and developmental potential in live mouse oocytes.

PEARL: Protein Eluting Alginate with Recombinant Lactobacilli.

Engineered living materials (ELMs) made of bacteria in hydrogels have shown considerable promise for therapeutic applications through controlled and sustained release of complex biopharmaceuticals at low costs and with reduced wastage. While most therapeutic ELMs use E. coli due to its large genetic toolbox, most live biotherapeutic bacteria in development are lactic acid bacteria due to native health benefits they offer.

[Sexuality of the couple during pregnancy after assisted reproductive technology: A comparative study].

Objective: To study the sexuality of pregnant women after assisted reproductive technology (ART).

Methods: This was a prospective multicenter study based on two questionnaires: the Female Sexual Function Index (FSFI) and the Couple Satisfaction Index 32 (CSI 32). Two groups were compared: pregnancies following ART and spontaneous pregnancies.

Painful vision loss during air travel after vitrectomy with air tamponade: a case report.

Background: While the potentially hazardous effects of intraocular perfluorocarbon gases during air travel have been recognized, the equivalent risk of intraocular air tamponade is less known and has, to the best of our knowledge, not been reported yet.

Case Presentation: A 52-year-old white female experienced a complete loss of vision and pain in her left eye during air travel following pars plana vitrectomy with air tamponade. Clinical and multimodal imaging findings only a few hours after emergency landing indicated a transient central retinal artery occlusion due to a significant increase in intraocular pressure during the flight.

Brain Hypertrophy in Patients With Mesial Temporal Lobe Epilepsy With Hippocampal Sclerosis and Its Clinical Correlates.

Background And Objectives: Mesial temporal lobe epilepsy (mTLE) is generally associated with focal brain atrophy, but little knowledge exists on possible disease-related hypertrophy of brain structures. We hypothesized that repeated seizures or adaptive plasticity may lead to focal brain hypertrophy and aimed to investigate associated clinical correlates.

Methods: In this cohort study, we included patients with mTLE undergoing detailed epilepsy evaluations and matched healthy volunteers (HVs) from 2 tertiary centers (discovery and validation cohorts).

Perioperative severity of acute appendicitis during the confinement related to SARS COVID-19: a retrospective comparative cohort.

Objective: To evaluate the perioperative severity of acute appendicitis during the COVID-19 pandemic compared to the same periods in 2018 and 2019 in the Nancy-Metz region, France. Acute appendicitis is a common surgical emergency that can lead to severe complications if not treated promptly. The COVID-19 pandemic and subsequent lockdowns resulted in reduced hospital visits, potentially delaying treatment for appendicitis and increasing perioperative severity.

Beyond risk preferences in sequential decision-making: How probability representation, sequential structure and choice perseverance bias optimal search.

Sequential decision-making, where choices are made one after the other, is an important aspect of our daily lives. For example, when searching for a job, an apartment, or deciding when to buy or sell a stock, people often have to make decisions without knowing what future opportunities might arise. These situations, which are known as optimal stopping problems, involve a risk associated with the decision to either stop or continue searching.

Rational use of immunoglobulins (IVIgs and SCIgs) in secondary antibody deficiencies.

Immunoglobulins for intravenous use (IVIgs) and subcutaneous use (SCIgs) can prevent recurrent and severe infections in patients with secondary antibody deficiencies that are frequently linked to haematological/oncological malignancies as well as other clinical conditions and their respective treatments. Even so, as IVIgs and SCIgs are costly and their supply is limited, their clinical use must be optimised. The aim of this position paper is to provide structured practical guidance on the optimal use of IVIgs and SCIgs in secondary antibody deficiencies, particularly in haematological and oncological practice.

Mechanistic insights into uptake, transfer and exchange of metal ions by the three-metal clusters of a metalloprotein.

Metallothioneins (MTs) are small proteins that coordinate d-block metal ions in sulfur-metal clusters to control metal ion concentrations within the cell. Here we study metal cluster formation in the MT of the periwinkle Littorina littorea (LlMT) by nuclear magnetic resonance (NMR). We demonstrate that the three Cd ions in each domain are taken up highly cooperatively, that is, in an all-or-none fashion, with a four- to six-fold higher affinity for the C-terminal domain.

OPTICAL COHERENCE TOMOGRAPHY FEATURES ASSOCIATED WITH VITREOMACULAR TRACTION RELEASE AND MACULAR HOLE SIZE PROGRESSION FOLLOWING TREATMENT WITH OCRIPLASMIN.

Purpose: To evaluate OCT features for vitreomacular traction (VMT) release and change in macular hole (MH) size after treatment with ocriplasmin.

Methods: Patients who had undergone treatment with ocriplasmin for VMT with or without MH ≤400 µm were included. The main outcomes were VMT release and changes in minimum linear diameter MH size at 4 weeks in MHs that persisted.

Synthesis of colicin Ia neoglycoproteins: tools towards glyco-engineering of bacterial cell surfaces.

Colicins are antimicrobial proteins produced by certain strains of that function as offensive weapons against closely-related competitor strains. Their bactericidal properties and narrow bacterial targeting range has made them of therapeutic interest. Furthermore, the applications of engineered non-bactericidal colicins are of interest as a cell surface-directed protein anchor for decorating with biomolecules.

Novel murine closed-loop auditory stimulation paradigm elicits macrostructural sleep benefits in neurodegeneration.

Boosting slow-wave activity (SWA) by modulating slow waves through closed-loop auditory stimulation (CLAS) might provide a powerful non-pharmacological tool to investigate the link between sleep and neurodegeneration. Here, we established mouse CLAS (mCLAS)-mediated SWA enhancement and explored its effects on sleep deficits in neurodegeneration, by targeting the up-phase of slow waves in mouse models of Alzheimer's disease (AD, Tg2576) and Parkinson's disease (PD, M83). We found that tracking a 2 Hz component of slow waves leads to highest precision of non-rapid eye movement (NREM) sleep detection in mice, and that its combination with a 30° up-phase target produces a significant 15-30% SWA increase from baseline in wild-type (WT) and transgenic (TG) mice versus a mock stimulation group.

Neurofeedback-enabled beta power control with a fully implanted DBS system in patients with Parkinson's disease.

Objective: Parkinsonian motor symptoms are linked to pathologically increased beta oscillations in the basal ganglia. Studies with externalised deep brain stimulation electrodes showed that Parkinson patients were able to rapidly gain control over these pathological basal ganglia signals through neurofeedback. Studies with fully implanted deep brain stimulation systems duplicating these promising results are required to grant transferability to daily application.

Mannose-Presenting "Glyco-Colicins" Convert the Bacterial Cell Surface into a Multivalent Adsorption Site for Adherent Bacteria.

Biofilm formation is integral to the pathogenesis of numerous adherent bacteria and contributes to antimicrobial resistance (AMR). The rising threat of AMR means the need to develop novel nonbactericidal antiadhesion approaches against such bacteria is more urgent than ever. Both adherent-invasive (AIEC, implicated in inflammatory bowel disease) and uropathogenic (UPEC, responsible for ∼80% of urinary tract infections) adhere to terminal mannose sugars on epithelial glycoproteins through the FimH adhesin on their type 1 pilus.

Exploring the local field potential signal from the subthalamic nucleus for phase-targeted auditory stimulation in Parkinson's disease.

Background: Enhancing slow waves, the electrophysiological (EEG) manifestation of non-rapid eye movement (NREM) sleep, could potentially benefit patients with Parkinson's disease (PD) by improving sleep quality and slowing disease progression. Phase-targeted auditory stimulation (PTAS) is an approach to enhance slow waves, which are detected in real-time in the surface EEG signal.

Objective: We aimed to test whether the local-field potential of the subthalamic nucleus (STN-LFP) can be used to detect frontal slow waves and assess the electrophysiological changes related to PTAS.
