Decreased timing to vasospasm prophylaxis improves outcomes among patients with aneurysmal subarachnoid hemorrhage (aSAH) on prehospital CCBs, ARBs, or ACE-inhibitors.

Introduction: Aneurysmal subarachnoid hemorrhage (aSAH) patients are given calcium channel blockers (CCBs) to prevent brain vessel vasospasm. We hypothesized that preinjury antihypertensive use may protect against vasospasm. It remains unclear whether the timing of in-hospital CCB initiation affects the vasospasm risk in this population.

Blood Lead Levels and Their Association with Iron Deficiency and Anemia in Children.

Lead is a ubiquitous and neurotoxic heavy metal particularly harmful to children, who are more susceptible than adults to its toxic effects. The prevalence of lead poisoning and iron deficiency (ID) is high in socioeconomically vulnerable child populations, negatively affecting neurocognitive development in children. Although numerous studies have shown the association between blood lead levels (BLL) and ID, the issue remains controversial.

Leptin receptor expression in blood mononuclear cells of lactating women is associated with infant body weight: Potential role as a molecular biomarker.

Background: Molecular biomarkers of maternal leptin resistance associated with infant weight are needed.

Objectives: To evaluate gene expression of leptin receptor (LEPR), suppressor of cytokine signalling 3 (SOCS3) and insulin receptor in peripheral blood mononuclear cells (PBMCs) of lactating women and their relationship with infant body weight and adiposity.

Methods: At day 10 postpartum, maternal gene expression in PBMCs as well as leptin and insulin concentrations in plasma and milk were assessed (n = 68).

Oxidation‑reduction potential parameters worsen following intraarterial therapy in patients with reduced collateral circulation and middle cerebral artery occlusions.

Collateral circulation is important for cerebral perfusion in acute ischemic strokes. Monitoring the oxidation-reduction potential (ORP) may be useful to assess collateral status or treatment efficacy. The objectives of the present study were to determine if the ORP was associated with collateral circulation status in middle cerebral artery (MCA) occlusions and to identify patterns in the ORP and the collateral circulation status among patients treated with intraarterial therapy (IAT) over time.

Effectiveness of weekly and daily iron administration for the prevention of iron deficiency anemia in infants.

Introduction. Iron deficiency (ID) is the most prevalent nutritional deficiency and the main cause of anemia in infants. There is consensus on daily iron supplementation as a preventive strategy; and weekly iron supplementation has also been shown to be effective, but evidence in infants is scarce.
