BACKGROUND: Familial long QT syndrome (LQTS) is a primary arrhythmogenic disorder caused by mutations in ion channel genes. The phenotype ranges from asymptomatic individuals to sudden cardiac arrest and death. LQTS is a rare but significant health problem for which global data should exist. This study sought to provide the first clinical and genetic description of Australian families with LQTS. METHODS: We performed a cross-sectional study to evaluate clinical and genetic features of families with LQTS...

Spinocerebellar degeneration (SCD) is a neurodegenerative disease characterized by progressive cerebellar ataxia. SCD has a wide range of clinical, pathological, and genetic features, including whether the disease is sporadic or hereditary, and whether it manifests as purely cerebellar or affects multiple systems. Therefore, the classification of SCD has been complicated and has changed over time. Recent advances in genetic testing have shed light on the classification of hereditary SCD. In contrast, the classification of sporadic SCD remains chaotic and there exist nomenclature discrepancies in sporadic SCD between Japanese and English literature...

BACKGROUND/PURPOSE: Patients with hypertrophic cardiomyopathy (HCM) have elevated risk for sudden cardiac death (SCD). Our study aimed to quantitatively characterize microvolt T-wave alternans (TWA), a potential arrhythmia risk stratification tool, in this HCM patient population. METHODS: TWA was analyzed with the quantitative modified moving average (MMA) in 132 HCM patients undergoing treadmill exercise testing, grouped according to Maron score risk factors as high-risk (H-Risk, n=67,), or low-risk (L-Risk, n=65, without these risk factors)...

Sickle cell disease (SCD) is an inherited haemoglobin disorder, associated with recurrent painful episodes, ongoing haemolytic anaemia and progressive multi-organ damage. Until the early 1990s, survival beyond the fourth decade for a patient with SCD was considered unusual and prompted case reports. Nowadays, in countries with developed health care systems, more than 90 percent of newborns with SCD survive into adulthood. Nevertheless, their life expectancy is still shortened by more than two decades compared to the general population...

PURPOSE: Prolactin regulatory element-binding protein (PREB), a member of the WD-repeat protein family, has been recognized as a transcriptional factor that regulates prolactin promoter activity in the anterior pituitary of rats. PREB is expressed not only in the pituitary but also in various other tissues, including the adipose tissue. Previous studies have shown that PREB acts as a transcriptional regulator and suppresses the expression of the adiponectin gene in cultured 3T3L1 preadipocytes...

Since 1998, the National Institutes of Health has funded 5 randomized controlled trials (RCTs) for primary and secondary prevention of strokes in children with sickle cell anemia (SCA). In a systematic fashion, these trials have significantly advanced the care of children with SCA. In the absence of an RCT, clinicians are often compelled to make decisions at the bedside, based on experience, observational studies, and principles of hematology. We will provide an initial example that describes how a team-based, learning collaborative developed a multisite standard care protocol with a low budget (<$10 000 per year) to overcome the intrinsic limitations of advancing the care of neurologic complications in sickle cell disease (SCD)...

Blood transfusion remains an important therapeutic intervention in patients with sickle cell disease (SCD), aiming to both increase the oxygen carrying capacity of blood and to reduce the complications of vaso-occlusion. Simple, manual exchange and automated exchange can be effective in reducing the acute and chronic complications of SCD, and the advantages and disadvantages of each methodology mean they all have a role in different situations. Evidence for the role of emergency transfusion in the management of the acute complications of SCD, including acute pain and acute chest syndrome, comes from observational data...

Red blood cell (RBC) transfusions are critical for treatment and prevention of complications of sickle cell disease (SCD), and most SCD patients will receive 1 or more transfusions by age 20. However, SCD alloimmunization remains a serious complication of transfusions that can lead to life-threatening acute and delayed transfusion reactions. Alloimmunization rates are higher in SCD patients most likely due to RBC antigenic differences between largely white donors vs mainly African-American recipients and frequency of transfusions...

BACKGROUND: Many older people worry about cognitive decline. Early cognitive screening in an anonymous and easily accessible manner may reassure older people who are unnecessarily worried about normal cognitive aging while it may also expedite help seeking in case of suspicious cognitive decline. OBJECTIVE: To develop and validate online and telephone-based automated self-tests of cognitive function. METHODS: We examined the feasibility and validity of the self-tests in a prospective study of 117 participants of whom 34 had subjective cognitive decline (SCD), 30 had mild cognitive impairment (MCI), and 53 had dementia...

Sudden cardiac death (SCD) is a tragic event affecting millions of individuals worldwide. Although several studies have investigated the epidemiology of SCD, these studies may have been affected by reporting and referral biases, which are reflected in the very different incidence rates and causes of deaths that have previously been reported. Among SCD victims aged < 36 years, inherited cardiac diseases are well known to play an important role. However, the extent to which inherited cardiac diseases also play a role in SCD victims aged < 50 years has not been completely described...

After the success story of implantable cardioverter/defibrillator systems, prevention of sudden cardiac death (SCD) remains one of the main duties in cardiology. For patients with unkown or transient risk profile for SCD, a wearable cardioverter/defibrillator (WCD) has been established for temporary and effective prevention of sudden arrhythmic death. Several studies have shown safety and efficacy of the WCD, even though randomized studies proving a mortality benefit are still lacking. This review provides an overview of actual WCD data and usage, special indications and possible risks and complications...

Priv- Doz, Dr Johannes Sperzel
Wearable cardioverter defibrillators (WCD), initially available in 2002, have recently experienced more routine use in many institutions as a means of preventing sudden cardiac death (SCD) prior to implantable cardioverter defibrillator (ICD) evaluation or implantation. WCD differ from ICD by their noninvasive nature, making them well suited for patient populations who have a chance for significant cardiac recovery (such as after an acute myocardial infarction). Despite their noninvasive nature, WCD treatment of sustained ventricular tachyarrhythmias is highly successful...

Sickle cell disease (SCD) is an increasing global health burden. This inherited disease is characterised by a remarkable phenotypic heterogeneity, which can only partly be explained by genetic factors. Environmental factors are likely to play an important role but studies of their impact on disease severity are limited and their results are often inconsistent. This study investigated associations between a range of environmental factors and hospital admissions of young patients with SCD in London and in Paris between 2008 and 2012...

BACKGROUND: Transition from pediatric to adult care is a vulnerable time for young adults with sickle cell disease (SCD); however, improvements in transition are limited by a lack of quality indicators. The purpose of this study was to establish quality indicators for transition in SCD and to determine the optimal timing between the final pediatric visit and the first adult provider visit. PROCEDURE: We conducted a modified Delphi survey to reach a consensus on which quality indicators are most important for a successful transition...

Overt ischaemic stroke is one of the most devastating complications in children with sickle cell disease (SCD). The compensatory response to anaemia in SCD includes an increase in cerebral blood flow (CBF) by accessing cerebrovascular dilatory reserve. Exhaustion of dilatory reserve secondary to anaemic stress may lead to cerebral ischaemia. The purpose of this study was to investigate CBF and cerebrovascular reactivity (CVR) using magnetic resonance imaging (MRI) in children with SCD and to correlate these with haematological markers of anaemia...

With improvements in the care of patients with sickle hemoglobinopathies, sickle cell disease (SCD) has evolved from a disease that was fatal in childhood into one in which most survive past their 5th decade and some into old age. As a result, the renal complications of sickle hemoglobinopathies, which are age dependent, have emerged as a common and serious complication of SCD. Approximately 14 - 18% of mortality in SCD is attributed to chronic kidney disease (CKD), which develops in 1/3 of individuals with SCD and progresses to end-stage renal disease in 4 - 18% of them...

Sudden cardiac death (SCD) from ventricular fibrillation (VF) during coronary artery disease (CAD) is a leading cause of total and cardiovascular mortality, and in more than half of SCD cases VF occurs as the first symptom of CAD. Several epidemiological studies have shown that sudden death of a family member is a risk factor for SCD and VF during acute myocardial infarction (MI), independent of traditional risk factors including family history of MI, suggesting a genetic component in the susceptibility to VF...

BACKGROUND: Complications related to sickle cell disease (SCD) result in significant declines in health-related quality of life (HRQOL). While hydroxyurea reduces SCD complications, adherence remains suboptimal. The study's objectives were to assess the feasibility of Internet-based electronic assessment of HRQOL in SCD clinic and to examine the relationship between HRQOL and hydroxyurea adherence in adolescents and young adults (AYAs) with SCD. PROCEDURE: A cross-sectional survey was administered on tablets to 34 AYAs (12-22 years old) in a SCD clinic from January through December 2015...

Spinocerebellar degeneration (SCD) is a group of disorders characterized by progressive ataxia caused by dysfunction and atrophy of the cerebellum or its projections. Approximately one-third of SCD cases are familial SCD, the majority of which are attributed to CAG triplet repeat expansions including spinocerebellar ataxia (SCA)1, SCA2, Machado-Joseph disease (MJD)/SCA3, SCA6, SCA8, SCA12, SCA17, and dentate-rubro-pallido-luysian atrophy (DRPLA). The triplet repeat number of the alleles representing complete penetrance varies among diseases...
