Transplantation of donor-derived allogeneic hematopoietic cells causes increased survival in patients suffering from various blood cancers and other hematologic and immunologic diseases. However, this health benefit is limited to certain patients. One major complication is graft-versus-host disease (GVHD) that occurs when donor-derived immune cells recognize host cells/tissues as foreign and perpetrate subsequent destruction. Cytokines are a major class of effector molecules that are involved in GVHD pathogenesis...

Vascular changes during spontaneous headache attacks have been studied over the last 30 years. The interest in cerebral vessels in headache research was initially due to the hypothesis of cerebral vessels as the pain source. Here, we review the knowledge gained by measuring the cerebral vasculature during spontaneous primary headache attacks with the use of single photon emission tomography (SPECT), positron emission tomography (PET), magnetic resonance imaging (MRA) and transcranial Doppler (TCD). Furthermore, the use of near-infrared spectroscopy in headache research is reviewed...

To investigate the effects of fluid resuscitation on cerebral hemodynamics in sepsis, the following set of transcranial Doppler (TCD) parameters was used: maximal change in flow velocity (FV) during stroke onset (acc), maximal FV during first (sys1) or second (sys2) phase of systole and mean diastolic FV (dias@560). We aim to evaluate changes in cerebral hemodynamics that result from (i) sepsis and (ii) adequate fluid resuscitation in critically ill septic patients. In the majority of 16 septic patients sys2 was initially absent but reappeared during the period of fluid resuscitation; whereas sys2 absence was never seen in healthy controls...

Transcranial Doppler (TCD) is able to detect cerebral hemodynamic changes in real-time. Impairment of cerebral blood flow during veno-arterial (VA) extracorporeal membrane oxygenation (ECMO) treatment is referred to in the literature. Several cerebrovascular complications can affect VA ECMO patients, eventually leading to brain death (BD). Transcranial Doppler is a worldwide accepted technique for cerebral circulatory arrest (CCA) diagnosis for BD confirmation, and in Italy, it is mandatory in certain clinical conditions...

Stroke is one of the most severe complications to affect children with sickle cell anaemia (SCA). Transcranial doppler (TCD) is an accurate and non-invasive method to determine stroke risk. Randomised controlled trials have demonstrated the efficacy of chronic transfusion therapy in stroke prevention based on risk stratification determined by TCD velocities. This has led to the regular use of TCD monitoring for children with SCA in order to determine stroke risk. Significant resource allocation is necessary to facilitate training, quality assurance and failsafe arrangements for non-attenders...

INTRODUCTION: The most important parameter needed for appropriate management of pregnant women is accurate Gestational Age (GA). Routine sonographic estimation of GA by using Biparietal Diameter (BPD), Femur Length (FL), Abdominal Circumference (AC) and Head Circumference (HC) assumed important role in management of pregnancy. However, these parameters have limitations. BPD and HC are not reliable in case of moulding of foetal head in third trimester. Similarly, femur length is shortened in cases of achondroplasia...

Sickle cell disease (SCD) is a common cause of cerebrovascular disease in childhood. Primary stroke prevention is effective using transcranial Doppler (TCD) scans to measure intracranial blood velocities, and regular blood transfusions or hydroxycarbamide when these are abnormal. Inadequate TCD scans occur when it is not possible to measure velocities in all the main arteries. We have investigated the prevalence and significance of this in a retrospective audit of 3915 TCD scans in 1191 children, performed between 2008 and 2015...

T cell-depleted (TCD) allogeneic hematopoietic stem cell transplantation (HSCT) is curative treatment for hematologic malignancies in adults, shown to reduce graft-versus-host disease (GVHD) without increased relapse. We retrospectively reviewed a single-center, 11-year experience of 214 patients aged ≥ 55 years to determine tolerability and efficacy in the older adult. Most patients (70%) had myeloid diseases, and most acute leukemias were in remission. Median age was 61 years, with related and unrelated donors >8/10 HLA matched...

The threshold velocity ≥200 cm/s at transcranial Doppler (TCD) evaluation is a useful cut-off for preventing the stroke (STOP trial) in pediatric patients with sickle cell disease (SCD), term including different types of sickle genotypes. Scanty data are available for adult SCD patients. We compared intracranial blood flow velocities between adult SCD patients and controls using transcranial color Doppler (TCCD), measuring the peak of systolic velocity (PSV) with the insonation angle correction and the pulsatility index (PI), an indicator of endothelial elasticity...

Non-enzymatic browning (NEB) in canned peach halves in syrup during storage was investigated. Absorbance at 420 nm (A420), colorimetric parameters (CIELab, TCD and La/b), fructose, glucose and sucrose, total sugar, organic acids, ascorbic acid (AA), dehydroascorbic acid, and 2,3-diketogulonic acid were used to estimate the extent of NEB during 1 year of storage at 30 °C and the relationships between each of these parameters and A420 were established. The investigation was carried out to explore the possibility of replacing the E330 commonly used as acidifier by turbid or clarified lemon juice (TLJ or CLJ) to obtain a product having good nutrition with better retention of quality...
