Children with sickle cell anaemia (SCA) and conditional transcranial Doppler (TCD) flow velocities (conditional 170-199 cm/s; normal less then 170 cm/s) have an increased risk of stroke. The Sickle Cell Clinical Research and Intervention Program (SCCRIP), a lifetime observational study, assessed the influence of haematological markers on TCD velocities. In children (≤16 years) with SCA (HbSS/HbSβ0 -thalassaemia) and conditional TCD velocities (n = 32), increases in haemoglobin and in fetal haemoglobin after hydroxyurea initiation were significantly associated with decreases in TCD velocities. The benefit of pharmacological intervention to increase haemoglobin and fetal haemoglobin and normalise TCD velocities was demonstrated in this real-world dataset.Diabetes is a chronic metabolic disorder associated with the accelerated development of macrovascular (atherosclerosis and coronary artery disease) and microvascular complications (nephropathy, retinopathy and neuropathy), which remain the principal cause of mortality and morbidity in this population. Current understanding of cellular and molecular pathways of diabetes-driven vascular complications, as well as therapeutic interventions has arisen from studying disease pathogenesis in animal models. Diabetes-associated vascular complications are multi-faceted, involving the interaction between various cellular and molecular pathways. Thus, the choice of an appropriate animal model to study vascular pathogenesis is important in our quest to identify innovative and mechanism-based targeted therapies to reduce the burden of diabetic complications. Herein, we provide up-to-date information on available mouse models of both Type 1 and Type 2 diabetic vascular complications as well as experimental analysis and research outputs.
To estimate the direct economic burden of tuberculous meningitis (TBM) in China for the first time.

Patients who were first diagnosed with TBM from December 2015 to December 2018 in Western China Hospital were enrolled. We retrospectively collected data on demographic and clinical features, resource utilization, costs, and long-term outcomes. The patients were followed up for 15-53months. We performed a cost-of-illness study and analyzed the cost contributors with a generalized linear model.

In total, the cases of 154 TBM patients (95 males, 59 females, aged 14-82years) were reviewed. The average total direct cost per person was USD (United States dollars) 9,484 (range 1,822-67,285), with a mean direct medical cost of USD 8,901 (range 1,189-67,049). The average inpatient cost and drug cost after discharge were USD 6,837 (range 845-52,921) and USD 1,967 (range 0-60,423), respectively. The mean direct nonmedical cost was USD 583 (range 33-3,817), which accounted for 6.2% of the total direct cost. The average length of stay (LOS) in hospital was 25.0days (range 6-152). A total of 117 of the patients (76.0%) had good outcomes (mRS=0-2). There was no significant difference in the costs, LOS, or outcomes between rural and urban patients. Contributors to total direct cost were definite TBM, fever, coma, seizures, multidrug resistance, hydrocephalus, and poor long-term outcome.

Although the accessibility of medical resources in remote and rural regions has significantly improved in China, the cost of TBM imposes a catastrophic burden on patients.

Although the pathogenesis of idiopathic intracranial hypertension (IIH) is still poorly understood, the contribution of inflammatory mechanisms has been proposed in its pathophysiology.

This study aimed to measure serum tumor necrosis factor-α (TNF-α) levels in patients with IIH and to examine its relationship with clinical and ophthalmological parameters and cerebrospinal fluid (CSF) opening pressure.

Thirty-six IIH patients and 30healthy subjects were enrolled in the study. Patients were subjected to complete neurological, general, and ophthalmological assessments. Pemrametostat molecular weight Serum TNF-α levels were measured for patients and controls using the enzyme-linked immunosorbent assay.

Serum TNF-α levels were significantly higher in IIH patients compared to healthy controls (p value <.001). Serum TNF-α level was significantly negatively correlated with grade of perimetry and CSF opening pressure (r=-.36, p value=.02), (r=-.37, p value=.02) respectively. However, serum TNF-α was not significantly correlated either with age at onset, disease duration, BMI, headache severity, relapse rate, visual acuity, or papilloedema grade. Serum TNF-α was found to be a significant predictor of the severity of the visual field affection in IIH patients, as one-grade increase of the perimetric grading was associated with a decrease in serum TNF-α by 13.96ng/ml.

Altered serum TNF-α levels may suggest the potential involvement of pro-inflammatory mechanisms in the pathogenesis of IIH. Serum TNF-α level may be an indicator of the severity of the visual field affection in IIH.

Some disease-modifying and curative therapies have increased haemoglobin (Hb) levels to exceed 100 g/l, a threshold above which complications from red blood cell (RBC) transfusions have occurred, raising concern about whole-blood viscosity-related complications with these therapies. Here we discuss the rationale behind this limit, the effect of viscosity on blood flow and the applicability of this Hb threshold to therapies for SCD beyond RBC transfusions.There is limited understanding of the impact of frailty on clinical outcomes in patients with myelofibrosis (MF). In this retrospective cohort study on 439 chronic phase MF patients [mean age 68·7 ± 12 years; median follow-up 3·4 years (IQR 0·4-8·6)] from 2004 till 2018, we used a 35-variable frailty index (FI) to categorise patient's frailty status as fit (FI less then 0·2, reference), prefrail (FI 0·2-0·29) or frail (FI ≥ 0·3). The association of frailty with overall survival (OS) and cumulative JAK inhibitor (JAKi) therapy failure was measured using hazard ratio (HR, 95% CI). In multivariable analysis, prefrail (HR 1·7, 1·1-2·5) and frail patients (HR 2·9, 1·6-5·5), those with higher DIPSS score (HR 2·5, 1·6-3·9) and transfusion dependency (HR 1·9, 1·3-2·9) had shorter OS. In a subset analysis of patients on JAKi treatment (n = 222), frail patients (HR 2·5, 1·1-5·7), patients with higher DIPSS score (HR 1·7, 1·0-3·1) and transfusion dependence (HR 1·7, 1·1-2·7) had higher cumulative incidence of JAKi failure.
