Rapid eye movement dependency is associated with increased inflammatory activity in obstructive sleep apnea syndrome

REM-dependent OSAS has some typical characteristics that distinguish it from stage-independent OSAS. These include a preference for younger age, female gender, and milder disease severity. Although these features suggest a benign course for this phenotype, recent literature shows that it is also associated with various cardiometabolic consequences. In our retrospective study, we found that PDW and SII, two accessible blood parameters, indicate an increased inflammatory status in this subtype. Our results highlight the need for close follow-up in patients with REM-dependent OSAS, as increased systemic inflammation can have negative consequences.

Assistive tools for classifying neurological disorders using fMRI and deep learning: A guide and example

In this article, we provide a guide to assistive tools that can simplify and increase the accessibility of fMRI and deep-learning methods for neurological disease diagnoses. We also detail an example of one such pipeline that can semiautonomously classify autism spectrum disorder.

Olfactory dysfunction as an early predictor for post-COVID condition at 1-year follow-up

Olfactory dysfunction as an early predictor for post-COVID condition at 1-year follow-up

Objectively assessed olfactory dysfunction at one to three months after COVID-19, but not subjective olfactory symptoms, predicted post-COVID condition (PCC) at one year. We propose that olfactory screening in the early post-acute phase of COVID-19 infection might identify individuals that are at higher risk of developing long-term health sequalae.

Topological differences of striato-thalamo-cortical circuit in functional brain network between premature ejaculation patients with and without depression

Topological differences of striato-thalamo-cortical circuit in functional brain network between premature ejaculation patients with and without depression

Premature ejaculation (PE) is often accompanied by abnormal psychological factors, such as depression. We collected resting-state fMRI data of PE patients with and without depression, as well as healthy controls. Graph theory analysis of functional brain networks underlined the topological changes of pallidum and thalamus as a neuroimaging phenotype for depressive PE.

Modulation of habenular and nucleus accumbens functional connectivity by ketamine in major depression

Modulation of habenular and nucleus accumbens functional connectivity by ketamine in major depression

We investigated how ketamine treatment perturbs static and dynamic functional connectivity from reward circuitry in treatment resistant depression. We found that ketamine produces functional connectivity changes between the habenula and visual cortex, and changes in dynamic functional connectivity between the habenula, nucleus accumbens, visual cortex, and posterior cingulate cortex were associated with greater treatment response.

Task-induced deactivation dysfunction during reward processing is associated with low self-esteem in a possible subtype of major depression

Task-induced deactivation dysfunction during reward processing is associated with low self-esteem in a possible subtype of major depression

Self-esteem in patients with major depressive disorder (MDD) correlated negatively with reward-related activity changes in the pregenual anterior cingulate cortex (pgACC) and the ventral striatum. This suggests that a previously described MDD subtype with reward-related overactivations in pgACC and ventral striatum is clinically characterized by low self-esteem.

Episodic memory network characteristics in patients with amnestic mild cognitive impairment accompanied by executive function impairment

The study found that amnestic mild cognitive impairment (aMCI) patients with lower executive function (aMCI-lowEF) exhibit more severe cognitive impairment, decreased cerebral glucose metabolism, and elevated AV45 levels compared to those with higher executive function (aMCI-highEF). Significant increased functional connectivity in the left superior temporal gyrus of the episodic memory network (EMN) were observed in aMCI-lowEF group. These findings underscore the impact of executive function on EMN alterations in aMCI patients.

Low triiodothyronine (T3) levels predict worse outcomes in autoimmune encephalitis—A meta-analysis of current literature

The findings of our study suggest that low fT3 levels might be related to a more severe disease state, implying the significance of thyroid hormones in Autoimmune Encephalitis pathogenesis. This finding is crucial in not only improving the early diagnosis of severe autoimmune encephalitis but also in the efficient management of the disease.

Contrast-enhanced transcranial Doppler for the detection of right-to-left shunt: A new provocation method with a syringe-modified Valsalva maneuver

A new provocation method with a syringe-modified Valsalva maneuver (sm-VM) during Contrast-enhanced transcranial Doppler (cTCD) was proposed in this study. Compared to cTCD detected at resting state and with conventional Valsalva maneuver, cTCD with sm-VM could further increase the positive detection rate of RLS. These findings support the use of this method in clinical practice.
