Access to acute stroke unit (ASU) care is known to vary worldwide. We aimed to quantify regional variations in the various components of ASU care.
Secondary analysis of the Head Positioning in acute Stroke Trial (HeadPoST), an international, multicentre, cluster crossover trial of head-up versus head-down positioning in 11,093 acute stroke patients at 114 hospitals in 9 countries. Patients characteristics and 11 standard components of processes of care were described according to ASU admission within and across four economically-defined regional groups (Australia/UK, China [includes Taiwan], India/Sri Lanka, and South America [Brazil/Chile/Colombia]). Variations in process of ASU care estimates were obtained in hierarchical mixed models, with adjustment for study design and potential patient- and hospital-level confounders.
Of 11,086 patients included in analyses, 59.7% (n=6620) had an ASU admission. In China, India/Sri Lanka and South America, ASU patients were older, had greater neurological severity and more premorbid conditions than non-ASU patients. ASU patients were more likely to receive reperfusion therapy and multidisciplinary care within regions, but the components of care varied across regions. With Australia/UK as reference, patients in other regions had a lower probability of receiving reperfusion therapy, especially in India/Sri Lanka (adjusted odds ratio [aOR] 0.27, 95% confidence interval [CI] 0.12-0.63) and multidisciplinary care (mainly in formal dysphagia assessment, physiotherapy and occupational therapy).
There is significant variation in the components of stroke care across economically-defined regions of the world. Ongoing efforts are required to reduce disparities and optimise health outcomes, especially in resource poor areas.

The supplementary motor area (SMA) is involved in several aspects of motor control and its can be associated to a contralateral motor deficit and speech disorders. After the resection of low-grade gliomas, this syndrome is diffusely reported but it is rarely investigated in high-grade gliomas. SMA deficits may resolve completely or with minor sequelae within weeks. Whether this condition of transient deficit affects survival, was not previously investigated, and is not currently understood.
The study aimed to perform an accurate investigation concerning the real clinical and prognostic impact of the postoperative SMA syndrome in order to shed light over its relationship to survival parameters and postoperative functional status of the patients.
We performed a retrospective review of a series of 176 surgically treated patients suffering from Glioblastomas. Tumors classified as Group A Involving the SMA and Group B Lesion located outside and distal to the SMA but in anatomical relationship to primary motor cortices (PM1) or corticospinal tract (CST), in order to investigate differences concerning immunohistochemical and molecular profiles in regard to the survival parameters.
Although lesions involving SMA demonstrated a significantly higher volume in respect to their general counterparts they did not significantly differ in concerns to the molecular patterns, pre and postoperative KPS scores and in PFS and OS findings.
In our cohort SMA-syndrome is reversible and therefore guarantees a satisfactory functional status at follow-up, apparently not compromising survival when compared to other lesions affecting the primary or cortical motor area -spinal tract.

Preterm infants often require assisted ventilation, however ventilation when applied to the immature lung can initiate ventilator-induced lung injury (VILI). The biotrauma which underscores VILI is largely undefined, and is likely to involve vascular injury responses, including hemostasis. We aimed to use a ventilated, preterm lamb model to (1) characterize regional alterations in hemostatic mediators within the lung and (2) assess the functional impact of protein alterations on hemostasis by analyzing temporal thrombin generation.
Preterm lambs delivered at 124 to 127days gestation received 90min of mechanical ventilation (positive end-expiratory pressure=8cm H
O, V
=6-8ml/kg) and were compared with unventilated control lambs. At study completion, lung tissue was taken from standardized nondependent and gravity-dependent regions, and Orbitrap-mass spectrometry and KEGG were used to identify and map regional alterations in hemostasis pathway members. Temporal alterations in plasma thrombin generation were assessed.
Ventilation was distributed towards the nondependent lung. Significant changes in hemostatic protein abundance, were detected at a two-fold higher rate in the nondependent lung when compared with the gravity-dependent lung. Seven proteins were uniquely altered in non-dependent lung (SERPINA1, MYL12A, RAP1B, RHOA, ITGB1, A2M, GNAI2), compared with a single proteins in gravity-dependent lung (COL1A2). Four proteins were altered in both regions (VTN, FGG, FGA, and ACTB). read more Tissue protein alterations were mirrored by plasma hypocoagulability at 90-minutes of ventilation.
We observed regionally specific, hemostatic alterations within the preterm lung together with disturbed fibrinolysis following a short period of mechanical ventilation.

The underlying mechanisms have not yet been fully understood. Hypothalamic-pituitary-adrenal (HPA) axis, as the central stress response system, regulates cardiometabolic homeostasis and is implicated in the progression of various adverse health effects caused by inhalational airborne pollutant exposure. In this study, we investigated whether ambient PM2.5 exposure activates HPA axis and its effect mediating PM2.5-induced pulmonary inflammation. C57Bl/6 J mice were intratracheally instilled with different concentrations of diesel exhaust PM2.5 (DEP), and plasma was harvested at different times. Assessments of plasma stress hormones revealed that DEP instillation dose- and time-dependently increased mouse circulating corticosterone and adrenocorticotropic hormone (ACTH) levels, strongly supporting that DEP instillation activates HPA axis. To determine which components of DEP activate HPA axis, C57Bl/6J mice were intratracheally instilled with water-soluble and -insoluble fractions of DEP.
