Purpose: To report central nervous system involvement after varicella zoster virus infection.
Methods: We evaluated the frequency and type of neurological complications in patients initially presenting with ophthalmic herpes zoster at an ophthalmological department in a Danish university hospital, over a 7-year period.
Results: Of the 110 immunocompetent patients who presented with initial ophthalmic zoster, six (5.5%) suffered from neurological complications other than post-herpetic neuralgia. Four experienced isolated cranial motor nerve palsies, one patient had meningitis with a favourable outcome and one patient had severe encephalitis with a poor clinical outcome.
Conclusions: Central nervous system involvement after varicella zoster virus infection is an uncommon, but potentially life-threatening, complication. Early recognition of neurological complications prompts acute, appropriate antiviral treatment.

Perivascular adipose tissue (PVAT) is a dynamic tissue that affects vascular function and cardiovascular health. The connection between PVAT, the immune system, obesity, and vascular disease is complex and plays a pivotal role in the pathogenesis of vascular diseases such as atherosclerosis, hypertension, and vascular inflammation. In cardiometabolic diseases, PVAT becomes a significant source of proflammatory adipokines, leading to increased infiltration of immune cells, in cardiometabolic diseases, PVAT becomes a significant source of proinflammatory adipokines, leading to increased infiltration of immune cells, promoting vascular smooth muscle cell proliferation and migrationpromoting vascular smooth muscle cell proliferation and migration.

Diverse macrophage populations inhabit the rodent and human central nervous system (CNS), including microglia in the parenchyma and border-associated macrophages (BAMs) in the meninges, choroid plexus, and perivascular spaces. These innate immune phagocytes are essential in brain development and maintaining homeostasis, but they also play diverse roles in neurological diseases. In this review, we highlight the emerging roles of CNS macrophages in regulating vascular function in health and disease.

Multiple sclerosis (MS) is a chronic autoimmune disease that affects the central nervous system (CNS). The etiology of MS remains elusive, with a complex interplay of genetic and environmental factors contributing to its pathogenesis. Recent studies showed mitochondrial DNA (mtDNA) as a potential player in the development and progression of MS.

Background: Half of people post pulmonary embolism (PE) experience ongoing symptoms such as dyspnoea, anxiety and depression, exercise limitation and fatigue. These symptoms can reduce their quality of life (QoL), psychological wellbeing, and functional capacity. The efficacy of rehabilitation interventions to prevent and manage these symptoms has not been established.
