Summary. X-chromosome-linked ichthyosis is caused by mutation or deletion of the STS gene associated with a deficiency of the enzyme steroid sulphatase, located in the distal part of the short arm of the X chromosome (Xp22.3-pter), close to the pseudo-autosomal region. Depending on its size, it can present as an isolated entity or combined with a syndrome caused by neighbouring genes, thus associating itself with other monogenic diseases as well as other mental disorders. The most relevant findings from the literature review are the importance of the Xp22.3-pter region and the higher incidence of neurological disorders among males (attention deficit hyperactivity disorder, autism and X-linked mental retardation). The role and implication of these genes in the disease are discussed and the authors suggest a possible contribution of the gene PNPLA4, which was originally described as GS2 and codes for calcium-independent phospholipase A2 beta, involved in lipoprotein metabolism, as one of the causes of autism. Improvements have been observed following treatment with citicoline, thanks to the role this nootropic plays in the biosynthesis of structural phospholipids involved in the formation and repair of the neuronal membrane. © 2012 Revista de Neurología.

Platelets | Year: 2016

Abstract: Background: Mean platelet volume (MPV) is a simple and reliable indicator of platelet size that correlates with platelet activation and their ability to aggregate. We studied the predictive value of MPV in patients with non-ST-segment elevation myocardial infarction (NSTEMI) treated with percutaneous coronary intervention (PCI). Methods: We analyzed the consecutive records of 1001 patients who were hospitalized due to NSTEMI at our center. The primary end point was a composite end point that included the rates of all-cause death, non-fatal myocardial infarction, and acute coronary syndrome (ACS) driven revascularization at 12 months. The enrolled patients were stratified according to the quartile of the MPV level at admission. Results: Along with the increasing quartile of MPV, the 12-month composite end point increased significantly (p = 0.010), and this association remained significant after the risk-adjusted analyses (per 1 fL higher MPV; adjusted hazard ratio [HR] 1.13; 95% confidence interval [CI] 1.02–1.27; p = 0.026). In the multivariate analysis, the MPV was also an independent factor of all-cause mortality (per 1 fL increase; adjusted HR 1.34; 95% CI 1.12–1.61; p = 0.0014) and death or non-fatal myocardial infarction (per 1 fL increase; adjusted HR 1.16; 95% CI 1.03–1.31; p = 0.017). Conclusion: In patients with NSTEMI treated with PCI, a high MPV value was associated with a significantly increased incidence of long-term adverse events, particularly for all-cause mortality. © 2016 Taylor & Francis.

INTRODUCTION: Previous studies have shown that an elevated neutrophil-to-lymphocyte ratio (NLR) was associated with a poorer long-term prognosis in patients with heart failure (HF). Objectives We aimed to study the predictive value of the NLR in patients with left ventricular ejection fraction of 35% or lower. The second objective was to establish whether the NLR has the same prognostic value in patients with ischemic and nonischemic HF. PATIENTS AND METHODS: The study group consisted of a cohort of patients with HF (1387 men, 347 women; median age, 61 years) from the prospective COMMIT-HF registry. The primary endpoint was all-cause mortality. Patients were divided into tertiles based on the NLR values on admission. The first (low), second (medium), and third (high) tertiles were defined as NLR ≤2.04 (n = 578), NLR 2.05.3.1 (n = 578) and NLR >3.1 (n = 578), respectively. RESULTS: During long-term follow-up, 443 deaths were reported. The 12-month mortality in patients in the third NLR tertile was almost 3-fold higher compared with those in the first tertile (7.61% vs 20.07%; P <0.001). In a multivariate analysis, the NLR was an independent factor of mortality (hazard ratio [HR], 2.31; 95% confidence interval [CI], 1.82.2.92; P <0.0001). In addition, the multivariate analysis revealed that the third NLR tertile in the ischemic HF group was an independent factor related to longterm mortality (HR, 1.51; 95% CI, 1.11.2.04; P = 0.008). In the nonischemic HF group, the influence of the NLR on long-term survival was not confirmed. CONCLUSIONS: The association between the NLR and the risk of death in long-term follow-up was confirmed only in the subgroup of patients with ischemic HF.

Purpose The renin-angiotensin-aldosterone system may influence in-stent restenosis (ISR) via angiotensin II, which stimulates the production of growth factors for smooth muscle cells. The aim of this work is to assess the influence of the rs1799752 polymorphism of the angiotensin-converting enzyme (ACE) gene and the rs699 polymorphism of the angiotensinogen (AGT) gene on the ISR in Polish patients with stable coronary artery disease (SCAD) who underwent stent implantation. Material/methods Two hundred and sixty-five patients with SCAD were included in the study. All patients underwent stent implantation upon admission to the hospital and had subsequent coronary angiography performed. The patients were divided into two groups - those with significant ISR (n = 53) and those without ISR (n = 212). The ACE polymorphism was assessed using the classical PCR method and the AGT polymorphism was determined using the TaqMan method for SNP genotyping. Results No difference in the frequency of angiographically significant ISR occurrence associated with the different ACE and AGT gene polymorphisms was observed. In a multivariable analysis, after correction for clinical variables, the relationship between the ACE and AGT genotypes within the scope of the analyzed polymorphisms and the process of restenosis was not found using a dominant, recessive and log-additive model. Late lumen loss was also independent of the genotypes of the polymorphisms before and after correction with angiographic variables. Conclusions The rs1799752 polymorphism and the rs699 polymorphism had no relationship with the occurrence of angiographically significant ISR and late lumen loss in a group of Polish patients who underwent metal stent implantation. © 2016 Medical University of Bialystok.

Microarray experiments are affected by several sources of variability. The paper demonstrates the major role of the day-to-day variability, it underlines the importance of a randomized block design when processing replicates over several days to avoid systematic biases and it proposes a simple algorithm that minimizes the day dependence. © 2006 IEEE.
