Stress can influence epilepsy in multiple ways. A relation between stress and seizures is often experienced by patients with epilepsy. Numerous questionnaire and diary studies have shown that stress is the most often reported seizure-precipitating factor in epilepsy. Acute stress can provoke epileptic seizures, and chronic stress increases seizure frequency. In addition to its effects on seizure susceptibility in patients with epilepsy, stress might also increase the risk of epilepsy development, especially when the stressors are severe, prolonged, or experienced early in life. Although the latter has not been fully resolved in humans, various preclinical epilepsy models have shown increased seizure susceptibility in naïve rodents after prenatal and early postnatal stress exposure. In the current review, we first provide an overview of the effects of stress on the brain. Thereafter, we discuss human as well as preclinical studies evaluating the relation between stress, epileptic seizures, and epileptogenesis, focusing on the epileptogenic effects of early life stress. Increased knowledge on the interaction between early life stress, seizures, and epileptogenesis could improve patient care and provide a basis for new treatment strategies for epilepsy.

Early childhood stress and amygdala structure in children and adolescents with neurodevelopmental disorders.

Children and adolescents with neurodevelopmental disorders such as autism spectrum disorder (ASD) and attention deficit hyperactivity disorder (ADHD) may be more susceptible to early life stress compared to their neurotypical peers. This increased susceptibility may be linked to regionally-specific changes in the striatum and amygdala, brain regions sensitive to stress and critical for shaping maladaptive behavioural responses. This study examined early life stress and its impact on striatal and amygdala development in 62 children and adolescents (35 males, mean age = 10.

Nutritional Epidemiology Group, School of Food Science and Nutrition, University of Leeds, Leeds, UK.
Purpose: The first 1000 days of life are critical for long-term health outcomes, and there is increasing concern about the suitability of commercial food products for infants, toddlers, and children. This study evaluates the compliance of UK commercial baby food products with WHO Nutrient and Promotion Profile Model (NPPM) guidelines.
Methods: Between February and April 2023, data on 469 baby food products marketed for infants and children under 36 months were collected from the online platforms of four major UK supermarkets.
Variability in Vaccine Response and Trajectory in Early Childhood and Association with Demographic Variables, Antibiotic Exposure and Infection Proneness.

Introduction: We sought to explore the variability of antibody responses to multiple vaccines during early life in individual children, assess the trajectory of each child longitudinally, determine the associations of demographic variables and antibiotic exposures with vaccine-induced immunity, and link vaccine responsiveness to infection proneness.
Methods: In 357 prospectively-recruited children, age six through 36 months, antibody levels to 13 routine vaccine antigens were measured in sera at multiple time points and normalized to their respective protective thresholds to categorize children into four groups: very low, low, normal, and high vaccine responder. Demographic variables and frequency of antibiotic exposure data were collected.
An innovative multicomponent compression system in a single bandage for venous leg ulcer and/or oedema treatment: a real-life study in 343 patients.

Department of Dermatology, Venereology, and Allergology of Katholisches Klinikum Bochum, Bochum, Germany.
Objective: This study aimed to evaluate the performance of an innovative multicomponent compression system in a single bandage (UrgoK1, Laboratoires Urgo, France) in the treatment of patients with venous leg ulcers (VLUs) and/or lower limb oedema in everyday practice.
Method: A prospective, observational, clinical study with the evaluated compression system was conducted in 39 centres in Germany between March 2022 and July 2023. Main outcomes included a description of the treated patients, changes in wound healing and oedema progression, local tolerance and acceptability of the compression system.
Hepatincolaceae (Alphaproteobacteria) are Distinct From Holosporales and Independently Evolved to Associate With Ecdysozoa.

Department of Biology and Biotechnology, University of Pavia, Pavia, Italy.
The Hepatincolaceae (Alphaproteobacteria) are a group of bacteria that inhabit the gut of arthropods and other ecdysozoans, associating extracellularly with microvilli. Previous phylogenetic studies, primarily single-gene analyses, suggested their relationship to the Holosporales, which includes intracellular bacteria in protist hosts. However, the genomics of Hepatincolaceae is still in its early stages.
