Article Abstract
Neuro-inflammation and blood-brain barrier (BBB) dysfunction are associated with depression. Evidence shows that adipokines enter the brain from the circulation, which regulates depressive behaviors. Omentin-1 is a newly identified adipocytokine that has anti-inflammatory effects, but little is known about its role in neuro-inflammation and mood-relevant behavior. Our results showed omentin-1 knockout mice (Omentin-1) increased susceptibility to anxiety and depressive-like behaviors, which are associated with abnormalities of cerebral blood flow (CBF) and impaired BBB permeability. Moreover, omentin-1 depletion significantly increased hippocampal pro-inflammatory cytokines (IL-1β, TNFα, IL-6), caused microglial activation, inhibited hippocampus neurogenesis, and resulted in autophagy impairment by dysregulating ATG genes. Omentin-1 deficiency also sensitized mice to the behavioral changes induced by lipopolysaccharide (LPS), suggesting that omentin-1 could rescue neuro-inflammation by acting as an anti-depressant. Our in vitro microglia cell culture data confirmed that recombinant omentin-1 suppresses microglial activation and pro-inflammatory cytokine expression induced by LPS. Our study suggests that omentin-1 can be used as a promising therapeutic agent for the prevention or treatment of depression by providing a barrier-promoting effect and an endogenous anti-inflammatory balance to downregulate the proinflammatory cytokines.

Characteristics and Clinical Outcomes of Women with Polycystic Ovary Syndrome After Bariatric Surgery.

Center for Health Policy and Health Services Research, Henry Ford Health System, Detroit, MI, USA.
Background: Polycystic ovary syndrome (PCOS) commonly co-occurs with obesity, medical comorbidities, and psychiatric symptoms. Bariatric surgery is an effective treatment for co-occurring obesity and PCOS. While the incidence of PCOS declines substantially after bariatric surgery, the condition is still present for a subset of women.

Background: Anxiety commonly affects older individuals with negative consequences on various physical and motor performances such as balance. When coupled with age-related muscular strength loss, the effects on the ability to perform daily tasks could be particularly detrimental, particularly in older women who are more susceptible to anxiety, muscular strength losses and falls. The study aimed to verify the effects of anxiety on balance performance in relation to muscular strength level in healthy older women.

The COVID-19 pandemic prompted governments worldwide to introduce social distancing measures, including school closures and restrictions on in-person socialising. However, adherence to social distancing was challenging for many - particularly adolescents, for whom social interaction is crucial for development. The current study aimed to identify individual-level influences on adherence to social distancing in a longitudinal sample of adolescents aged 11-20 years in England, who took part in a randomised controlled trial.

Article Synopsis
- The study investigates the neurobiological factors that make individuals susceptible to fatigue after a mild COVID-19 infection, aiming to understand the link between brain structure and post-COVID neuropsychiatric symptoms.
- Researchers used neuropsychiatric assessments and MRI scans on individuals who had COVID-19 and a control group to analyze brain regions related to fatigue.
- Results indicate that specific brain areas, particularly the right dorsolateral prefrontal cortex, are linked to fatigue severity and can predict ongoing fatigue symptoms months after the infection, shedding light on the neural underpinnings of post-COVID conditions.
Polycystic Ovary Syndrome and Eating Disorders-A Literature Review.
J Clin Med
December 2024
Clinical Department of Gynecologic Surgery and Oncology, Wroclaw Medical University, Borowska 213, 50-556 Wroclaw, Poland.
Polycystic ovary syndrome (PCOS) is a complex endocrine disorder that affects women of reproductive age and is characterized by hyperandrogenism, ovulatory dysfunction and polycystic ovarian morphology. PCOS is often associated with hormonal imbalances, metabolic dysfunction and comorbid psychiatric disorders, including eating disorders (EDs). The review identifies key hormonal factors-serotonin, leptin, insulin, ghrelin, kisspeptin and cortisol-and their roles in the pathophysiology of PCOS and associated psychiatric symptoms.
