Safety and practicality study of using an exoskeleton in acute neurosurgery patients.

Introduction: Early mobilization is key in neurologically impaired persons, limiting complications and improving long-term recovery. Self-balanced exoskeletons are used in rehabilitation departments to help patients stand and walk. We report the first case series of exoskeleton use in acute neurosurgery and intensive care patients, evaluating safety, clinical feasibility and patients' satisfaction.

Distinct metabolic responses to heme in inflammatory human and mouse macrophages - Role of nitric oxide.

Activation of inflammation is tightly associated with metabolic reprogramming in macrophages. The iron-containing tetrapyrrole heme can induce pro-oxidant and pro-inflammatory effects in murine macrophages, but has been associated with polarization towards an anti-inflammatory phenotype in human macrophages. In the current study, we compared the regulatory responses to heme and the prototypical Toll-like receptor (TLR)4 ligand lipopolysaccharide (LPS) in human and mouse macrophages with a particular focus on alterations of cellular bioenergetics.

Modelling daisy quorum drive: A short-term bridge across engineered fitness valleys.

Engineered gene-drive techniques for population modification and/or suppression have the potential for tackling complex challenges, including reducing the spread of diseases and invasive species. Gene-drive systems with low threshold frequencies for invasion, such as homing-based gene drive, require initially few transgenic individuals to spread and are therefore easy to introduce. The self-propelled behavior of such drives presents a double-edged sword, however, as the low threshold can allow transgenic elements to expand beyond a target population.

Solid Organ Transplant Litigation at One of Europe's Largest University Hospitals.

Due to its intrinsic complexity and the principle of collective solidarity that governs it, solid organ transplantation (SOT) seems to have been spared from the increase in litigation related to medical activity. Litigation relating to solid organ transplantation that took place in the 29 units of the Assistance Publique-Hôpitaux de Paris and was the subject of a judicial decision between 2015 and 2022 was studied. A total of 52 cases of SOT were recorded, all in adults, representing 1.

Morphological, Microstructural, and In Situ Chemical Characteristics of Siderite Produced by Iron-Reducing Bacteria.

Dissimilatory iron-reducing bacteria (DIRB) oxidize organic matter or hydrogen and reduce ferric iron to form Fe(II)-bearing minerals, such as magnetite and siderite. However, compared with magnetite, which was extensively studied, the mineralization process and mechanisms of siderite remain unclear. Here, with the combination of advanced electron microscopy and synchrotron-based scanning transmission X-ray microscopy (STXM) approaches, we studied in detail the morphological, structural, and chemical features of biogenic siderite via a growth experiment with MR-4.

Enhancing Agency in Posttraumatic Stress Disorder Therapies Through Sensorimotor Technologies.

Posttraumatic stress disorder (PTSD) is a significant public health concern, with only a third of patients recovering within a year of treatment. While PTSD often disrupts the sense of body ownership and sense of agency (SA), attention to the SA in trauma has been lacking. This perspective paper explores the loss of the SA in PTSD and its relevance in the development of symptoms.

Sun exposure and protection habits: Self-reported attitudes, knowledge and behaviours.

Background: As exposure to UV radiation is the primary modifiable environmental risk factor associated with skin cancer, it remains the principal focus of most prevention strategies. Numerous sun protection campaigns have been implemented worldwide; however, their impact on the actual incidence and mortality rates of skin cancer seems to be limited. To create successful skin cancer prevention campaigns, it is important to have a comprehensive understanding of individuals' attitudes and behaviours regarding sun protection.

Impact of Medical Education in Middle School, Directed by a Science Teacher and a Healthcare Professional, on Self-Medication and Care System Literacy. A Comparative Prospective Cohort Study.

To assess the immediate and six-month follow-up effects of medical education simultaneously provided by a practitioner and a science teacher on middle school students regarding self-medication and knowledge of the healthcare system. Two groups were constituted: the learning group (L group), with students receiving an interactive medical education, and the control group (C group), which included students without medical education. Both groups were evaluated by using a six-multiple choice question (MCQ) evaluation form: three times for L group - just before the medical workshop (T0), immediately after the medical workshop (T1) and at six-month follow-up after the medical workshop (T2) - and only the evaluation at T0 for students in C group.

Urgent considerations for booster vaccination strategies against Ebola virus disease.

With two endorsed and prophylactic vaccines against Zaire ebolavirus (referred to hereafter as EBOV), the number of individuals vaccinated against EBOV worldwide is estimated to range between 500 000 and 1 000 000 individuals, increasing with every renewed EBOV threat and vaccination campaign. Therefore, re-exposure of previously vaccinated health-care workers, and possibly community members, could become more frequent. In the absence of long-term data on vaccine efficacy and duration of protection, we urgently need to understand revaccination strategies that could maximise the level of protection.

Long-term Outcome of Risankizumab in Crohn's Disease: a Real-world GETAID Study.

Background & Aims: The aim of this study was to assess the long-term effectiveness and safety of risankizumab maintenance treatment in a large real-world cohort of patients with Crohn's Disease (CD).

Methods: From May 2021 to August 2023, all consecutive patients with CD treated with risankizumab in 25 GETAID centers have been retrospectively included. The primary endpoint was steroid-free clinical remission (Harvey Bradshaw Index [HBI] <5) at 52 weeks.

A practical approach to the modern diagnosis and classification of T- and NK-cell lymphomas.

T- and natural killer (NK)-cell lymphomas are neoplasms derived from immature T cells (lymphoblastic lymphomas), or more commonly, from mature T and NK cells (peripheral T-cell lymphomas, PTCLs). PTCLs are rare but show marked biological and clinical diversity. They are usually aggressive and may present in lymph nodes, blood, bone marrow, or other organs.

Oxidative stress promotes liver fibrosis by modulating the microRNA-144 and SIN3A-p38 pathways in hepatic stellate cells.

: Reactive oxygen species (ROS) act as modulators triggering cellular dysfunctions and organ damage including liver fibrosis in which hepatic stellate cell (HSC) activation plays a key role. Previous studies suggest that microRNA-144 (miR-144) acts as a pro-oxidant molecule; however, whether and how miR-144 affects HSC activation and liver fibrosis remain unknown. Carbon tetrachloride (CCl) and bile duct ligation (BDL)-induced experimental liver fibrosis models were used.

Functional connectivity of the amygdala subnuclei in various mood states of bipolar disorder.

Amygdala functional dysconnectivity lies at the heart of the pathophysiology of bipolar disorder (BD). Recent preclinical studies suggest that the amygdala is a heterogeneous group of nuclei, whose specific connectivity could drive positive or negative emotional valence. We investigated functional connectivity (FC) changes within these circuits emerging from each amygdala's subdivision in 127 patients with BD in different mood states and 131 healthy controls (HC), who underwent resting-state functional MRI.

The contribution of cannabis use to the increased psychosis risk among minority ethnic groups in Europe.

Background: We examined whether cannabis use contributes to the increased risk of psychotic disorder for non-western minorities in Europe.

Methods: We used data from the EU-GEI study (collected at sites in Spain, Italy, France, the United Kingdom, and the Netherlands) on 825 first-episode patients and 1026 controls. We estimated the odds ratio (OR) of psychotic disorder for several groups of migrants compared with the local reference population, without and with adjustment for measures of cannabis use.

Complement Terminal Pathway Activation and Intrarenal Immune Response in C3 Glomerulopathy.

Key Points: We evidenced terminal pathway activation (C5b-9 deposits) in most of the glomeruli on kidney biopsy of C3 glomerulopathy. The amount of C5b-9 deposits correlated with disease prognosis in C3 glomerulopathy. Increased terminal pathway activation was found predominantly in a subgroup exhibiting an immuno-fibroblastic signature.
