Purpose Of Review: Sickle cell anemia (SCA) is an autosomal recessive inherited hemoglobinopathy that results in a high risk of stroke. SCA primarily affects an underserved minority population of children who are frequently not receiving effective, multi-disciplinary, preventative care. This article reviews primary and secondary stroke prevention and treatment for children with SCA for the general adult and pediatric neurologist, who may play an important role in providing critical neurologic evaluation and care to these children.

It is often poor compared with other chronic medical conditions or measured as a multidomain disease-specific construct. We previously reported outcomes in the Start Healing in Patients with Hydroxyurea (SHIP-HU) randomized controlled trial in adolescents and adults with SCD at six clinical sites.

The aim of the Sickle Cell Disease Treatment with Arginine Therapy (STArT) Trial is to provide definitive evidence regarding the efficacy of intravenous arginine as a treatment for acute SCD-VOE among children, adolescents, and young adults.
Methods: STArT is a double-blind, placebo-controlled, randomized, phase 3, multicenter trial of intravenous arginine therapy in 360 children, adolescents, and young adults who present with SCD-VOE.
In a cross-sectional analysis of baseline data from a randomized clinical trial, we studied 198 adolescents and adults aged 15+ with sickle cell disease. Interest was in assessing the relative strengths of the relationship of vaso-occlusive crisis (VOC) pain domains of intensity, frequency, and duration, with health-related quality of life (HRQOL). Variation in psychosocial, physical function, and pain expression domains of HRQOL was partially explained by frequency, intensity, and duration of VOC pain, separately and together, over and above differences in age, sex, genotype, and organ system damage.

Due to a lack of multicenter emergency department (ED) return visit rate data, the return visit rate following ED discharge for pediatric SCD pain treatment is currently unknown.
Procedure: A seven-site retrospective cohort study of discharged ED visits for pain by children with SCD was conducted using the Pediatric Emergency Care Applied Research Network Registry.
The study was conducted to examine prevalence of pulmonary embolism in children with sickle cell disease (SCD) and identify potential risk factors associated with pulmonary embolism in a single tertiary paediatric centre. Children with SCD between 0 and 21 years of age from January 2010 to January 2021 were included. Pulmonary embolism was initially identified using International Classification of Diseases (ICD)-9 or 10 codes and confirmed with manual chart review of identified cases.

Identification of risk factors influencing the duration of carriage of multidrug-resistant Gram-negative bacilli (MDR-GNB) may be useful for infection control. The aim of this study is to estimate the impact of several factors collected for routine hospital surveillance on the duration of carriage of selected MDR-GNB. From January 2015 to July 2021, patients with at least two clinical/surveillance samples positive for MDR-GNB different from ESBL-producing E.

Studies examining risk of pulmonary embolism (PE) in children with SCD are lacking. This study was conducted in children with SCD between 0-21 years of age using a nationwide administrative database in the United States- Pediatric Health Information System (PHIS) from January 2010 to June 2021.

We hypothesized that as hydroxyurea gained widespread use, surgical splenectomy among pediatric patients with SCD occurred at a higher rate and older age among those taking hydroxyurea.
Methods: In this retrospective cross-sectional study, the Pediatric Health Information System was queried for all SCD International Classification of Diseases 9/10 diagnosis codes and splenectomy procedure codes from January 1, 2005, to December 31, 2020.
A lack of adult sickle cell providers has long been blamed for poor satisfaction and access to specialty care for adults with sickle cell disease (SCD). We were interested in comparing how adolescent and adult patients already in established SCD centers perceived access and quality of care. Hydroxyurea-eligible patients aged 15 years and older were enrolled in the Start Healing in Patients with Hydroxyurea trial, which required them to be affiliated with a SCD specialist.

Dementia was one of the conditions focused on in an EU (European Union) project called "PARADISE" (Psychosocial fActors Relevant to brAin DISorders in Europe) that later produced a measure called PARADISE 24, developed within the biopsychosocial model proposed in the International Classification of Functioning Disability and Health (ICF). The aims of this study are to validate PARADISE 24 on a wider sample of patients with mild to moderate dementia to expand PARADISE 24 by defining a more specific scale for dementia, by adding 18 questions specifically selected for dementia, which eventually should be reduced to 12. We enrolled 123 persons with dementia, recruited between July 2017 and July 2019 in home care and long-term care facilities, in Italy, and 80 participants were recruited in Warsaw between January and July 2012 as part of a previous cross-sectional study.

Case management is an evidence-based health management strategy and in this regard patient navigators (PNs) may provide case management for SCA. We hypothesised that HU-eligible patients exposed to PNs would have improved indicators of starting HU and HU adherence.

Traditional use of disinfection challenge microorganisms and testing techniques, although widely used and applicable for chemical disinfection studies, do not provide as robust a challenge for testing the efficacy of a thermal disinfection process. Considerable research has been established in the literature to demonstrate the relationship between the thermal resistance of microorganisms to inactivation and the A0 method formula.

Less is known about the outcomes following robotic-assisted splenectomy (RS) for this indication. Our aim was to describe outcomes of RS to LS in pediatric patients with hematologic disorders in our institution.

Liver transplant resulted in resolution of liver dysfunction, decreased need for blood transfusions and eligibility for bone marrow transplantation. This case represents the third reported patient in the literature with severe PK deficiency who successfully underwent liver transplant as a result of profound cholestasis and liver failure.

We previously described a first-in-class CFTR modulator that functions as an amplifier to selectively increase CFTR expression and function. The amplifier mechanism is distinct from and complementary to corrector and potentiator classes of CFTR modulators.

While left ventricular outflow tract (LVOT) obstruction is relatively frequent in TTC patients, this complication has not been reported in the setting of rTTC yet. We describe the case of a female patient with rTTC complicated by LVOT obstruction and systolic anterior motion of mitral valve: the onset of these findings coincided with the regression of wall motion abnormalities.

Spinal cord injury (SCI) is a complicated neuropathological condition that results in functional dysfunction and paralysis. Various treatments have been proposed including drugs, biological factors and cells administered in several ways. Stem cell therapy offers a potentially revolutionary mode to repair the damaged spinal cord after injury.

Here, we demonstrate that patients bearing the rare mutation: c.3700 A>G, causing protein misprocessing and altered channel function-similar to ΔF508-CFTR, are unlikely to yield a robust Orkambi response.

Currently exercise training is a class I intervention as part of a multifactorial long-term process that includes: clinical assistance, assessment of global cardiovascular risk, identification of specific objective for each cardiovascular risk factor, formulation of an individual treatment plan with multiple intervention aimed at reduction of the risk, educational programs, planning of long term follow-up. This paper reviews the evidences of benefit of exercise in the most common heart diseases and describes the role of exercise training in the cardiac rehabilitation programs.
