The Relationship

The gut microbiome (GMB) plays an important role in developmental processes and has been implicated in the etiology of psychiatric disorders. However, the relationship between GMB and schizophrenia remains unclear. In this article, we review the existing evidence surrounding the gut microbiome in schizophrenia and the potential for antipsychotics to cause adverse metabolic events by altering the gut microbiome. We also evaluate the current evidence for the clinical use of probiotic and prebiotic treatment in schizophrenia. The current data on microbiome alteration in schizophrenia remain conflicting. Longitudinal and larger studies will help elucidate the confounding effect on the microbiome. Current studies help lay the groundwork for further investigations into the role of the GMB in the development, presentation, progression and potential treatment of schizophrenia.

: Cryptogenic stroke and its relation to the Patent Foramen Ovale (PFO) is a long-debated topic. Recent clinical trials have unequivocally established the relationship between cryptogenic strokes and paradoxical embolism across the PFO. This slit-like communication exists in everyone before birth, but most often closes shortly after birth. PFO may persist as a narrow channel of communication between the right and left atria in approximately 25-27% of adults. : In this review, we examine the clinical relevance of the PFO with analysis of the latest trials evaluating catheter-based closure of PFO’s for cryptogenic stroke. We also review the current evidence examining the use of antiplatelet medications versus anticoagulants for stroke prevention in those patients with PFO who do not qualify for closure per current guidelines.

This chapter examines the relationship between entrepreneurs and the communities in which they are embedded. It argues that the actions of entrepreneurs and their firms are contextually situated in specific geographies that make their actions endogenous in the development of place and define a place-specific institutional logic. This argument is at odds with the view that industry clustering is due to the role of incumbent firms. This chapter reconciles these views by adopting a temporal view, allowing both incumbents and geography to co-occur and influence clustering. It then considers the current evidence of entrepreneurs’ effects on regional resources and capacity, and concludes with suggestions for future research.

The Relationship

The burden of cognitive disorders is huge and still growing, however the etiology and the degree of cognitive impairment vary considerably. Neurodegenerative and vascular mechanisms were most frequently assessed in patients with dementia. Recent studies have shown the possible involvement of triglycerides levels in cognitive function through putative mechanisms such as brain blood barrier dysfunction or amyloid metabolism imbalance, but not all research in the field found this association. Several clinical studies evaluated the relationship between different forms of cognitive decline and levels of serum triglycerides, independent of other cardiovascular risk factors. This review focuses on the role of triglycerides in cognitive decline, cerebral amyloidosis and vascular impairment. Considering that the management of hypertriglyceridemia benefits from lifestyle modification, diet, and specific drug therapy, future studies are requested to appraise the triglycerides–cognitive impairment relationship.

Studies suggest that the bidirectional relationship existent between the gut microbiome (GM) and the central nervous system (CNS), or so-called the microbiome–gut–brain axis (MGBA), is involved in diverse neuropsychiatric diseases in children and adults. In pediatric age, most studies have focused on patients with autism. However, evidence of the role played by the MGBA in attention deficit/hyperactivity disorder (ADHD), the most common neurodevelopmental disorder in childhood, is still scanty and heterogeneous. This review aims to provide the current evidence on the functioning of the MGBA in pediatric patients with ADHD and the specific role of omega-3 polyunsaturated fatty acids (ω-3 PUFAs) in this interaction, as well as the potential of the GM as a therapeutic target for ADHD. We will explore: (1) the diverse communication pathways between the GM and the CNS; (2) changes in the GM composition in children and adolescents with ADHD and association with ADHD pathophysiology; (3) influence of the GM on the ω-3 PUFA imbalance characteristically found in ADHD; (4) interaction between the GM and circadian rhythm regulation, as sleep disorders are frequently comorbid with ADHD; (5) finally, we will evaluate the most recent studies on the use of probiotics in pediatric patients with ADHD.

Adolescents are spending more time interacting with peers online than in person, evidencing the need to examine this shift’s implications for adolescent loneliness and mental health. The current review examines research documenting an association between social media use and mental health, and highlights several specific areas that should be further explored as mechanisms within this relationship. Overall, it appears that frequency of social media use, the kind of social media use, the social environment, the platform used, and the potential for adverse events are especially important in understanding the relationship between social media use and adolescent mental health.

Emerging evidence suggests there is a gut-joint axis in spondyloarthritis (SpA). In a study, subclinical gut inflammation occurred in nearly 50% of SpA. Chronic gut inflammation also correlated with disease activity in SpA. Trillions of microorganisms reside in the human gut and interact with the human immune system. Dysbiosis affects gut immune homeostasis and triggers different autoimmune diseases including SpA. The absence of arthritis in HLA-B27 germ-free mice and the development of arthritis after the introduction of commensal bacteria to HLA-B27 germ-free mice proved to be the important role of gut bacteria in shaping SpA, other than the genetic factor. The recent advance in gene sequencing technology promotes the identification of microorganisms. In this review, we highlighted current evidence supporting the link between gut and axial SpA (axSpA). We also summarized available findings of gut microbiota and its interaction with the immune system in axSpA. Future research may explore the way to modulate gut microorganisms in axSpA and bring gut microbiome discoveries towards application.

Abstract Food is a vital need for everyone. Today, there is food for all, but the world still suffers from under- and over-nutrition and risk of cancer development and chronic diseases can follow both cases. Worldwide, cancer is a leading cause of mortality after cardiovascular disease; it is considered the second reason for death globally. Role of nutritional habits, the quality of food, the consumption of canned foods, genetically modified fruits and vegetables and exposed food to certain pesticides and carcinogens agents, and unhealthy lifestyle behaviours such as smoking, alcohol, obesity, and fast-foods consumption may be at risk to the development of some cancers. In recent decades, researchers have carried out attention in this field to improve the quality of life and to limit nutrition problems. Thus, this study aims to summarize current evidence on the relationship between nutritional factors and cancer expansion, how nutrition can be a heal and a source of fatal illness leading to death. In detail, this review will highlight the influence of specific foodstuffs on the threat of cancer incidence and recurrence by providing some examples of most carcinogenic compounds.

Abstract Background: Lithocholic acid are essential signaling molecules that mediate the relationship between the gut microbiome and liver function by regulating inflammation. The purpose of this study is to investigate the role of lithocholic acid in liver fibrosis. Methods: A liver fibrosis mouse model was induced by carbon tetrachloride followed by gavage of lithocholic acid, and the effects of lithocholic acid were evaluated by serum biochemical analysis and liver histology. Plasma cytokine levels and the number of immune cells were determined by cytometric bead array and flow cytometry, respectively. Results: Lithocholic acid treatment increased the recruitment of NK cells and reduced the activation of NKT cells, and reduced M1 macrophages differentiation and increased M2 macrophages differentiation. Furthermore, the lithocholic acid prevented inflammatory liver disease by reducing TNF-α and IL-22 secretion. However, the effect of lithocholic acid disappeared when the host gut microbiome was treated with antibiotics. Conclusions: It showed that the activation of lithocholic acid-mediated signaling was linked to the inhibition of inflammation and improvement of liver fibrosis. The role of lithocholic acid in liver fibrosis is mediated by the gut microbiome. The association between the gut microbiome, lithocholic acid, and liver function can serve as a therapeutic target for liver fibrosis.

Diabetes mellitus is one of the most common chronic medical conditions in the world. Increasing evidence suggests that chronic hyperglycemia can cause excessive production of free radicals, particularly reactive oxygen species (ROS). Free radicals play important roles in tissue damage in diabetes. The relationship between exposure to nanoparticles (NPs) and diabetes has been reported in many previous studies. Evaluation of the potential benefits and toxic effects of NPs on diabetic disorders is of importance. This review highlights studies on the relationship between NPs and oxidative stress (OS) as well as the possible mechanisms in diabetic animal models and humans.

ABSTRACT The discovery of immune checkpoint inhibitors (ICIs) has revolutionized the care of cancer patients. However, the response to ICI therapy exhibits substantial interindividual variability. Efforts have been directed to identify biomarkers that predict the clinical response to ICIs. In recent years, the gut microbiome has emerged as a critical player that influences the efficacy of immunotherapy. An increasing number of studies have suggested that the baseline composition of a patient's gut microbiota and its dysbiosis are correlated with the outcome of cancer immunotherapy. This review tackles the rapidly growing body of evidence evaluating the relationship between the gut microbiome and the response to ICI therapy. Additionally, this review highlights the impact of antibiotic-induced dysbiosis on ICI efficacy and discusses the possible therapeutic interventions to optimize the gut microbiota composition to augment immunotherapy efficacy.
