The case report that is the subject of this Commentary describes a 27-year-old woman, who, 3 months after a devastating low cervical myelitis, underwent intrathecal mesenchymal stem cell (MSC) infusions. Six hours after the third infusion, she became unconscious, febrile and cerebral MRI showed acute bitemporal and left cerebellar lesions, consistent with an acute disseminated encephalomyelitis. It is likely that this is the first reported patient with neuroinflammatory exacerbation after MSC therapy. This case suggests that, in addition to their malignant potential, autologous MSC expanded in vitro can exhibit immune-activating properties leading to autoimmune exacerbation.

Deficient neutrophil responses early in influenza infection promote viral replication and pulmonary inflammation.

Neutrophils play key protective roles in influenza infections, yet excessive neutrophilic inflammation is a hallmark of acute lung injury during severe infections. Phenotypic heterogeneity is increasingly recognized in neutrophil populations; however, how functional variation in neutrophils between individuals determine the diverse outcomes of influenza remains unclear. To examine immunologic responses that may drive varying outcomes in influenza, we infected C57BL/6 (B6) and A/J mice with mouse-adapted influenza A virus A/PR/8/34 H1N1.

Background: Disseminated intravascular coagulation (DIC) is a common complication in sepsis patients which exacerbates patient outcomes. The prevalence and outcomes of DIC in sepsis is wide-ranging and highly depends on the severity of the disease and diagnostic approaches utilized. Varied diagnostic criteria of DIC have been developed and their performance in diagnosis and prognosis is not consistent.

While studies have explored the incidence and prevalence of PSS, little is known about how early PSS develops and how many stroke survivors develop 'problematic' PSS that would benefit from pharmacological treatment.
Methods And Analysis: EPITOME is a prospective, international, observational, epidemiological study of participants (aged 18-90 years) who develop paresis within days 3-14 of a first-ever stroke that occurred within the past 4 weeks.
Introduction: Delirium is a common acute cognitive impairment characterised by confusion, disorientation and attention deficits, particularly prevalent in intensive care unit (ICU) settings. Given its significant impact on patients, caregivers and healthcare resources, preventing delirium in patients in the ICU is of paramount importance. This is the first randomised-controlled trial designed to evaluate the effects of a virtual reality-based sensory stimulation intervention on preventing delirium in ICU patients.

Introduction: Individuals with higher neurological levels of spinal cord injury (SCI) at or above the sixth thoracic segment (≥T6), exhibit impaired resting cardiovascular control and responses during upper-body exercise. Over time, impaired cardiovascular control predisposes individuals to lower cardiorespiratory fitness and thus a greater risk for cardiovascular disease and mortality. Non-invasive transcutaneous spinal cord stimulation (TSCS) has been shown to modulate cardiovascular responses at rest in individuals with SCI, yet its effectiveness to enhance exercise performance acutely, or promote superior physiological adaptations to exercise following an intervention, in an adequately powered cohort is unknown.
