Background: Childhood maltreatment is a major risk factor for the development of depression, as well as for imbalances in the immune system, including chronic low-grade inflammation. Less is known about potential immune imbalances in adolescent depression and the role of childhood maltreatment. Furthermore, accelerated epigenetic aging may contribute to the development of inflammation, but has never been examined in the context of adolescent depression.

Around 10% of the Western population is diagnosed with asthma, and this percentage is only expected to increase in the coming years. Allergic asthma often develops during early infancy and is characterized by chronic pulmonary type 2 inflammation and airway hyperresponsiveness. Severe viral infections in early life are thought to be a risk factor for allergic asthma.

Immune fitness refers to the body's ability to respond to health challenges by activating an appropriate immune response. Perceived immune fitness can be assessed using a single-item scale ranging from 0 (very poor) to 10 (excellent). The aim of the current study (n = 29 healthy volunteers) was to evaluate the relationship between perceived immune fitness and immune biomarker concentrations in saliva.

Introduction: Food allergies, like cow's milk allergy, significantly impact children, with sensitization often beginning during the first year of life. Human milk oligosaccharides (HMOs) may influence this process, as specific HMOs differentially affect mucosal immune responses . Given the distinct HMO profiles of secretor (Se+) and non-secretor (Se-) milk, we investigate how the full HMO profiles from Se+ and Se- milk affect immune responses in the absence or presence of a cow's milk allergen.

Several factors are linked to the pathophysiology of autism spectrum disorders (ASD); however, the molecular mechanisms of the condition remain unknown. As intestinal problems and gut microbiota dysbiosis are associated with ASD development and severity, recent studies have focused on elucidating the microbiota-gut-brain axis' involvement. This study aims to explore mechanisms through which gut microbiota might influence ASD.

Objective: Given that Parkinson's disease is a progressive disorder, with symptoms that worsen over time, our goal is to enhance the diagnosis of Parkinson's disease by utilizing machine learning techniques and microbiome analysis. The primary objective is to identify specific microbiome signatures that can reproducibly differentiate patients with Parkinson's disease from healthy controls.

Methods: We used four Parkinson-related datasets from the NCBI repository, focusing on stool samples.

Article Synopsis
  • - The study investigates how synbiotic supplements can help reduce allergic asthma symptoms in offspring exposed to environmental cigarette smoke and house-dust mites.
  • - Researchers found that pups from mothers exposed to cigarette smoke had increased lung resistance and elevated immune markers, indicating worse asthma symptoms, but synbiotics helped improve these conditions.
  • - By promoting healthy gut bacteria, synbiotic intervention in early life showed promise in reducing allergic reactions and suggests a potential strategy for preventing allergies in children affected by pollution.

Article Synopsis
  • Newborns have an underdeveloped immune system, making them vulnerable to infections like rotavirus (RV), which is a major cause of child mortality, especially in developing countries.
  • Maternal immunity plays a crucial role in providing protection against RV through pregnancy and breastfeeding, and this study investigates how enhancing maternal diet can boost newborn immunity.
  • Pregnant rats receiving a specific synbiotic showed pups with reduced RV infection severity and elevated levels of immune-related antibodies, indicating that this dietary intervention improves the pups' ability to fight off infections.

Degenerative joint disease osteoarthritis (OA) is characterized by the degeneration of cartilage, synovial inflammation and low-grade systemic inflammation in association with microbial dysbiosis and intestinal barrier defects. Butyrate is known for its anti-inflammatory and barrier protective effects and might benefit OA patients. In a double-blind placebo-controlled randomized trial, the effects of four to five weeks of oral treatment with sustained-release (SR) butyrate tablets (600 mg/day) on systemic inflammation and immune function were studied in hand OA patients.

Article Synopsis
  • - Early-life nutrition, particularly the inclusion of prebiotics like galacto-oligosaccharides and human milk oligosaccharides, can improve vaccine responses in infants, as shown in a study with mice.
  • - Mice on a specific diet (combination of GOS/lcFOS and HMOS) exhibited stronger immune responses, evidenced by increased ear swelling (a measure of delayed-type hypersensitivity) and higher levels of specific antibodies (IgG1).
  • - The diet enhanced the activation of immune cells, particularly memory B lymphocytes and Th1 cells, indicating that incorporating these prebiotics into infant formulas could lead to better immune development and vaccine efficacy in infants.

Quality of life (QoL) is traditionally assessed using multiple-item questionnaires. These can be either general, global assessments of QoL or disease-specific questionnaires. However, the use of single-item QoL scales is becoming increasingly popular, as these are more time- and cost-effective, with a readily available and easy-to-interpret outcome.

In many parts of the world, goat milk has been part of the human diet for millennia. Allergy to goat's milk, not associated with allergy to cow's milk, is a rare disorder, although some cases have been described. Goat milk proteins have substantial homology with cow's milk proteins and even show cross-reactivity; therefore, they are not advised as an alternative to cow's milk for infants with IgE-mediated cow's milk allergies.

After esophagectomy, an imbalanced inflammatory response increases the risk of postoperative morbidity. The vagus nerve modulates local and systemic inflammatory responses, but its pulmonary branches are transected during esophagectomy as part of the oncological resection, which may account for the high incidence of postoperative (pulmonary) complications. This study investigated the effect of electrical vagus nerve stimulation (VNS) on lipopolysaccharide (LPS)-induced lung injury in rats.

The alcohol hangover is a combination of negative mental and physical symptoms which can be experienced after a single episode of alcohol consumption, starting when blood alcohol concentration (BAC) approaches zero. A popular theory suggests that dehydration is the primary cause of alcohol hangover and that the consumption of water could alleviate hangover symptoms. Here, the current evidence on the relationship between hangover severity, thirst, and water consumption is summarized.
