Background: The persistent neurological symptoms seen in long COVID survivors are attributed to immune system dysfunctions and changes in the microbiome induced by SARS-CoV-2 infection. In addition to the initial respiratory manifestations, a significant portion of COVID-19 patients present with neurodegenerative symptoms. Our hypothesis suggests that disruptions in inflammatory signals and alterations in the gut microbiome post-COVID-19 play pivotal roles in the development of neurodegenerative complications among individuals experiencing prolonged effects of the disease.

Vagus nerve stimulation in treatment-resistant depression: A one-year, randomized, sham-controlled trial.

Background: Few treatments are available for individuals with marked treatment-resistant depression (TRD).

Objective: Evaluate the safety and effectiveness of FDA-approved adjunctive vagus nerve stimulation (VNS) in patients with marked TRD.

Methods: This 12-month, multicenter, double-blind, sham-controlled trial included 493 adults with marked treatment-resistant major depression who were randomized to active or no-stimulation sham VNS for 12 months.

Effects of vagus nerve stimulation on daily function and quality of life in markedly treatment-resistant major depression: Findings from a one-year, randomized, sham-controlled trial.

Background: Depression treatments aim to minimize symptom burden and optimize quality of life (QoL) and psychosocial function.

Objective: Compare the effects of adjunctive versus sham vagus nerve stimulation (VNS) on QoL and function in markedly treatment-resistant depression (TRD).

Methods: In this multicenter, double-blind, sham-controlled trial, 493 adults with TRD and ≥4 adequate but unsuccessful antidepressant treatment trials (current episode) were randomized to active (n = 249) or sham (n = 244) VNS (plus treatment as usual) over a 12-month observation period.

Draft genome sequences of sp. MMG031 and sp. MMG032 isolated from the dinoflagellate .

Here, we report the draft genome sequences of sp. MMG031 and sp. MMG032, isolated from coral-associated dinoflagellate , assembled and analyzed by undergraduate students participating in a Marine Microbial Genomics (MMG) course.

Biomarkers Unveiling the Interplay of Mind, Nervous System, and Immunity.

The field of psychoneuroimmunology has significantly expanded in the last few decades and so has our understanding of the bidirectional communications between the immune and central nervous systems (CNS). There is a preponderance of evidence supporting the fact that immunological pathways and neuroinflammation are involved in the pathophysiology of multiple neurological and mental health conditions. In this chapter, we have explored various neuroimmunological biomarkers involved in these pathways, responsible for developing and perpetuating different neuropsychiatric disorders.

Understanding stakeholders' perception on developing seagrass-associated tourism: Evidence from marine protected areas of Bintan Island, Indonesia.

Seagrass ecosystems provide vital services but face increasing threats from human activities. Marine protected areas (MPAs) aim to mitigate these threats, but inadequate funding and management hinder effective conservation. Seagrass-associated tourism presents an opportunity to fund conservation efforts, enhance MPA implementation, and improve local livelihoods.

Eating Disorder Risks Associated with Time Spent Using Social Media at an AMREC Population in the Coal Mining Region of Santa Catarina.

Comparing one's appearance to other people's and believing in an ideal body shape can negatively impact an individual. The probability of developing ED in individuals with high body dissatisfaction is higher than in the general population, leading to long-term emotional and metabolic damage. Populational studies on the prevalence of ED in Brazil are scarce in the literature.

Effects of paradoxical sleep deprivation on oxidative parameters in the serum and brain of mice submitted to the animal model of hyperglycemia.

The present study aimed to investigate the effects of paradoxical sleep deprivation (PSD) on behavioral and oxidative stress parameters in the brain and serum of mice submitted to the animal model of hyperglycemia induced by alloxan, mimicking the main symptom of diabetes mellitus (DM). Adults C57BL/6 male and female mice received an injection of alloxan, and ten days later, the animals were submitted to the PSD for 36 h. The animals' behavioral parameters were evaluated in the open-field test.

Clinical characteristics and treatment exposure of patients with marked treatment-resistant unipolar major depressive disorder: A RECOVER trial report.

Background: RECOVER is a randomized sham-controlled trial of vagus nerve stimulation and the largest such trial conducted with a psychiatric neuromodulation intervention.

Objective: To describe pre-implantation baseline clinical characteristics and treatment history of patients with unipolar, major depressive disorder (MDD), overall and as a function of exposure to interventional psychiatric treatments (INTs), including electroconvulsive therapy, transcranial magnetic stimulation, and esketamine.

Methods: Medical, psychiatric, and treatment records were reviewed by study investigators and an independent Study Eligibility Committee prior to study qualification.

Anti-manic effect of deep brain stimulation of the ventral tegmental area in an animal model of mania induced by methamphetamine.

Background: Treatment of refractory bipolar disorder (BD) is extremely challenging. Deep brain stimulation (DBS) holds promise as an effective treatment intervention. However, we still understand very little about the mechanisms of DBS and its application on BD.

Impact of COVID-19 on patients undergoing scheduled procedures for chronic venous disease.

Objective: The COVID-19 pandemic has drastically altered the medical landscape. Various strategies have been employed to preserve hospital beds, personal protective equipment, and other resources to accommodate the surges of COVID-19 positive patients, hospital overcapacities, and staffing shortages. This has had a dramatic effect on vascular surgical practice.

Opportunities and challenges for the use of deep brain stimulation in the treatment of refractory major depression.

Major Depressive Disorder continues to remain one of the most prevalent psychiatric diseases globally. Despite multiple trials of conventional therapies, a subset of patients fail to have adequate benefit to treatment. Deep brain stimulation (DBS) is a promising treatment in this difficult to treat population and has shown strong antidepressant effects across multiple cohorts.
