nitive declines. These findings provide the clinical evidence that CSF and blood exosomes Ng can be used as a cognitive biomarker for AD and MCI-AD, and further studies are needed to define the specific range of Ng values for diagnosis at the different stages of AD.According to the World Health Organization cardiovascular disease risk charts, the mortality rate of cardiovascular diseases in people is still high. The medical expenses caused by cardiovascular diseases are increasing daily, and the medical burden is becoming heavier; as such, it is imperative to prevent and cure cardiovascular diseases. A large number of scholars are analyzing the pathogenesis of cardiovascular diseases from various perspectives. Recent findings suggest that N6-methyladenosine (m6A) plays a multifaceted role in the cardiovascular system. m6A is a methylated modification product on RNA molecules and exists on various RNA molecules. It is one of the most common epigenetic modifications discovered to date. It regulates the expression of genes and subsequent responses. The amount of m6A is determined by methylases (writers) and demethylases (erasers). The third type of proteins, readers, selectively bind to m6A to regulate RNA stability and gene expression. In this paper, the relationship between m6A and related enzymes and cardiovascular structure and function was reviewed based on recent research results regarding the cardiovascular system.BACKGROUND Incomplete closure of the neural tube results in congenital anomalies called neural tube defects (NTD). These defects are rarely multiple, and are characterized by loss of central nervous system soft tissue and bony coverings, along with herniation of the involved part of the CNS through the defect. CASE REPORT A newborn female infant was delivered through planned cesarean section due to large occipital encephalocele diagnosed antenatally. The pregnancy was unplanned and the mother did not take folic acid prior to conception. Birth weight was 3.41 Kg. Upon delivery, the newborn was healthy, with an Apgar score of 8. The physical examination revealed 2 large pouches; one was over the occiput, and the other swelling was located over the nape of the neck. Brain MRI revealed large occipital encephalocele and cervical myelomeningocele. The 2 defects were repaired separately, with an uneventful postoperative course. CONCLUSIONS We report the rare occurrence of multiple NTD. Early repair, either as single or multiple procedures, is mandatory to avoid dramatic complications.BACKGROUND Despite the rapidly increasing attention being given to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection, more commonly known as coronavirus disease 2019 (COVID-19), the relationship between cardiovascular disease and COVID-19 has not been fully described.Methods and ResultsA systematic review was undertaken to summarize the important aspects of COVID-19 for cardiologists. Protection both for patients and healthcare providers, indication for treatments, collaboration with other departments and hospitals, and regular update of information are essentials to front COVID-19 patients. CONCLUSIONS Because the chief manifestations of COVID-19 infection are respiratory and acute respiratory distress syndrome, cardiologists do not see infected patients directly. Cardiologists need to be better prepared regarding standard disinfection procedures, and be aware of the indications for extracorporeal membrane oxygenation and its use in the critical care setting.BACKGROUND The excessive volume of contrast needed is a significant limitation of optical coherence tomography (OCT)-guided percutaneous coronary intervention (PCI). Low-molecular-weight dextran (LMWD) has been used for OCT image acquisition instead of contrast media. This study compared the effects of OCT-guided PCI using LMWD on renal function and clinical outcomes to those of intravascular ultrasound (IVUS)-guided PCI.Methods and ResultsIn all, 1,183 consecutive patients who underwent intracoronary imaging-guided PCI were enrolled in this single-center, retrospective, observational study. After propensity score matching, 133 pairs of patients were assigned to undergo either OCT-guided PCI using LMWD or IVUS-guided PCI. There was no significant change from baseline in the primary endpoint, serum creatinine concentrations, after the procedure in either group. There were no significant differences between the OCT and IVUS groups in the volume of contrast medium, the incidence of contrast-induced nephropathy (1.5% vs. 2.3%; P=0.65), and major adverse cardiovascular events (MACE) at 30 days (2.3% vs. 6.0%; P=0.12) and 12 months (2.3% vs. 3.0%; P=0.70) after the procedure. Kaplan-Meier analysis at the 12-month follow-up revealed no significant difference in the incidence of MACE between the 2 groups (P=0.75). buy Importazole CONCLUSIONS OCT-guided PCI using LMWD did not negatively affect renal function and achieved similar short- and long-term clinical outcomes to IVUS-guided PCI.Catheter ablation (CA) is considered first-line treatment for many patients with symptomatic arrhythmias. Indications for CA are constantly increasing, as is the number of procedures. Although CA is nowadays regarded a safe procedure, there is a risk of complications, including both bleeding- and thrombosis-related events. Several factors contribute to periprocedural risk; of these, patient coagulation status is of considerable clinical relevance. In this context, even a simple procedure poses a considerable challenge in a patient with coagulation disorder. However, the level of evidence regarding CA in patients with coagulation disorders is very low. Neither experts’ recommendations nor clinical guidelines have been presented so far. The aim of this article is to analyze potential procedure-related risks and provide clinicians with useful information and practical suggestions regarding optimization of procedural safety in patients with coagulation disorders.BACKGROUND Despite many effective strategies for the prevention of recurrent stroke, individuals who survive an initial stroke have been shown to be at high risk of recurrent stroke. The aim of this study was to investigate the current status of stroke recurrence after first-ever stroke using a population-based stroke registry in Japan.Methods and ResultsAs part of the Shiga Stroke and Heart Attack Registry, the Shiga Stroke Registry is an ongoing population-based stroke registry study that covers approximately 1.4 million residents of Shiga Prefecture, Japan. A total of 1,883 first-ever stroke survivors at 28 days was registered in 2011 and followed-up until the end of 2013. Recurrence was defined as any type of stroke after 28 days from the onset of an index event. Two-year cumulative recurrence rates were estimated using cumulative incidence function methods. Over a mean 2.1-year follow-up period, 120 patients experienced recurrent stroke and 389 patients died without recurrence. The 2-year cumulative recurrence rate was higher in patients with index ischemic stroke (6.
