Myelodysplastic syndromes (MDS) are a group of heterogeneous hematologic diseases. Chromosomal aberrations are important for the initiation, development, and progression of MDS. Detection of chromosomal abnormalities in MDS is important for categorization, risk stratification, therapeutic selection, and prognosis evaluation of the disease. Recent progress of multiple techniques has brought powerful molecular cytogenetic information to reveal copy number variation, uniparental disomy, and complex chromosomal aberrations in MDS...

BACKGROUND: Due to loss of hormonal protective effects, postmenopausal women have an increased cardiovascular (CV) risk. Chronic kidney disease (CKD) is a well-established risk factor for CV disease, but little is known whether mild-to-moderate kidney dysfunction is associated with atherosclerosis burden in the postmenopausal asymptomatic women. MATERIALS AND METHODS: Subclinical atherosclerosis was evaluated in 125 postmenopausal women with no clinical form of atherosclerosis, by carotid and femoral ultrasonography, ankle-brachial index (ABI), and flow-mediated dilation (FMD)...

Incidence of ischemic stroke and transient ischemic attack in young adults is rising. However, etiology remains unknown in 30-40% of these patients when current classification systems designed for the elderly are used. Our aim was to identify risk factors according to a pediatric approach, which might lead to both better identification of risk factors and provide a stepping stone for the understanding of disease mechanism, particularly in patients currently classified as "unknown etiology". Risk factors of 656 young stroke patients (aged 18-50) of the FUTURE study were categorized according to the "International Pediatric Stroke Study" (IPSS), with stratification on gender, age and stroke of "unknown etiology"...

Infections are one of the main causes of morbidity and mortality in the population. The choice of empirical treatment is one of the most common decisions facing the physician. This first decision has consequences in the prognosis of the patient and the costs associated with the process. This review attempts to summarize the aspects that can lead to failure of antibiotic treatment by considering microbiological and pharmacological aspects, patient profile and infectious focus control. In addition, a series of recommendations are established to minimize this risk, from the point of view of diagnostic accuracy, adequate severity stratification of the patient, knowledge of the pharmacokinetic and pharmacodynamic aspects of antibiotics and control of the infectious focus...

Large randomized controlled trials (RCTs) in preterm infants offer unique opportunities for mechanistic evaluation of the risk factors leading to serious diseases, as well as the actions of interventions designed to prevent them. Necrotizing enterocolitis (NEC) a serious inflammatory gut condition and late-onset sepsis (LOS) are common feeding and nutrition-related problems that may cause death or serious long-term morbidity and are key outcomes in two current UK National Institutes for Health Research (NIHR) trials...

Inpatient delirium improves with multicomponent interventions by hospital staff, though the resources needed are often limited. Risk-stratification to predict delirium is a useful first step to help triage resources, but the performance of risk-stratification as part of a functioning multicomponent pathway has not been assessed. We retrospectively studied the performance of a validated delirium prediction rule, the AWOL score, as a part of a multicomponent delirium care pathway in practice on a university hospital ward...

INTRODUCTION: Bone fractures fail to heal and form nonunions in roughly 5% of cases, with little expectation of spontaneous healing thereafter. We present a systematic review and meta-analysis of published papers that describe nonunions treated with low-intensity pulsed ultrasound (LIPUS). METHODS: Articles in PubMed, Ovid MEDLINE, CINAHL, AMED, EMBASE, Cochrane Library, and Scopus databases were searched, using an approach recommended by the Methodological Index for Non-Randomized Studies (MINORS), with a Level of Evidence rating by two reviewers independently...

Impaired left atrial emptying fraction (LAEF) is an important predictor of mortality in patients with heart failure. As it may reflect increased LV wall stress, it might predict ventricular arrhythmia (VA) specifically. This study evaluated the predictive value of LAEF assessed with cardiovascular magnetic resonance (CMR) imaging with respect to appropriate device therapy (ADT) for VA and compared its role with CMR assessed scar size and other risk factors. In total, 229 patients (68% male, 63 ± 10 years, 61% ischemic cardiomyopathy) with LV ejection fraction ≤35% who underwent CMR and implantable cardioverter defibrillator (ICD) implantation for primary prevention in 2005 to 2012 were included...

Co-morbidities increase markedly with aging, and they often negatively affect its prognosis. Although mortality with transcatheter mitral valve repair (TMVr) is significantly less than for open mitral valve surgery in patients at high surgical risk, it remains a concern to identify which patients will benefit from this treatment. Some prognostic metrics have been reported to guide better patient selection; however, universal risk stratification measures have not been established. This study aimed to determine if age-adjusted Charlson co-morbidity index (CCI) could predict mortality in patients who underwent TMVr and to assess its discriminatory performance in long-term outcomes...

Sudden cardiac death (SCD) has a strong familial component; however, our understanding of its genetic basis varies significantly according to the underlying causes. When coronary artery disease is involved, the predisposing genetic background is complex and despite some interesting findings it remains largely unknown. Quite different is the case of monogenic structural and non-structural heart diseases, in which a number of disease-causing genes have been established and are being used in clinical practice...

Raveendran A V, Abdul Hamid Zargar
For diabetic patients, fasting during Ramadan, the ninth month of the Islamic calendar, can cause wide fluctuations in blood sugar levels, posing a medical challenge for patients and physicians and increasing the risk of acute metabolic complications including hypoglycemia, hyperglycemia, diabetic ketoacidosis, dehydration, and thrombosis. Proper patient education, risk stratification, and modification of antidiabetic medications can reduce the risk of complications.

Dysregulated microRNA (miRNA) expression is observed during type 2 diabetes (T2D), although the consistency of miRNA expression across measurement platform and biological source is uncertain. Here we report miRNA profiling in the whole blood and serum of South African women with different levels of glucose tolerance, using next generation sequencing (NGS) and quantitative real time PCR (qRT-PCR). Whole blood-derived miRNAs from women with newly diagnosed T2D (n = 4), impaired glucose tolerance (IGT) (n = 4), and normal glucose tolerance (NGT) (n = 4) were subjected to NGS, whereafter transcript levels of selected miRNAs were quantified in the whole blood and serum of these women using qRT-PCR...
