Incident Stroke After First-Time TIA According to ABCD Score: A Nationwide Cohort Study.

Background And Objectives: Transient ischemic attack (TIA) is associated with a higher short-term incidence of stroke. However, long-term data on this association are lacking. Therefore, this study aimed to determine the long-term incidence of ischemic stroke after TIA according to ABCD score and to identify factors associated with stroke after TIA.

Long-term risk of heart failure in patients with postoperative atrial fibrillation following non-cardiac surgery: Insights from a nationwide cohort.

Aims: Atrial fibrillation (AF) is associated with heart failure (HF). However, it is unclear if postoperative AF (POAF) following non-cardiac surgery differs from non-surgical AF in terms of the risk of HF. We compared the long-term rate of incident HF in patients developing new-onset POAF following non-cardiac surgery with patients who did not develop POAF following non-cardiac surgery and patients with non-surgical non-valvular AF (NVAF).

Multimodality Imaging in Cardiomyopathies.

Cardiomyopathy, which is shortly defined as a disease of the myocardium, has a broad definition that includes many different diagnoses. Recent advances in cardiac imaging techniques, including basic and advanced echocardiography, computed tomography, nuclear medicine, and cardiac magnetic resonance, allow for a more accurate evaluation of volumes and thickness of cardiac chambers, systolic and diastolic function of the ventricules, and tissue structure. Multimodality imaging often provides the first clinical suspicion for specific etiologies, especially when the medical and family history is unclear, by identification of red flags of underlying systemic diseases.

Background: The present study aims to evaluate possible cardiac involvement in juvenile dermatomyositis (JDM) patients by conventional methods and cardiac magnetic resonance imaging (MRI) along with a systematic review of the literature on cardiac features in JDM.

Methods: The study group consisted of JDM patients who underwent cardiac MRI. We conducted a systematic review of the published literature involving JDM patients with cardiac involvement.

The effect of maternal weight on neonatal cardiac functions following diabetic and non-diabetic pregnancies.

Objective: We aimed to study myocardial functions of infants appropriate and large for gestational age (IDM-AGA, IDM-LGA) of diabetic mothers (IDM) and AGA and LGA infants of non-diabetic mothers comparatively.

Methods: Newborns were assessed between 24 and 72 h. M-Mode, pulsed wave, and tissue Doppler echocardiography were performed.

Validation of the newly developed Sleep Screening Questionnaire Children and Adolescents (SSQ-CA) with objective sleep measures.

Objectives: Objectively validated pediatric sleep questionnaires covering a broader age range and different sleep disturbances are lacking, therefore we developed the Sleep Screening Questionnaire Children and Adolescents (SSQ-CA) and compared it with objective sleep parameters.

Methods: This child-reported questionnaire was developed by a multidisciplinary panel and face validated. In a cross-sectional prospective design, participants aged 6-17, answered the questionnaire twice with 21-28 days in between, wore actigraphy (AG) and kept a sleep diary for seven nights and home-polysomnography (PSG) for one of these nights.

Probing the Influence of Novel Organometallic Copper(II) Complexes on Spinach PSII Photochemistry Using OJIP Fluorescence Transient Measurements.

Modern agricultural cultivation relies heavily on genetically modified plants that survive after exposure to herbicides that kill weeds. Despite this biotechnology, there is a growing need for new sustainable, environmentally friendly, and biodegradable herbicides. We developed a novel [CuL]Br complex (L = bis{4H-1,3,5-triazino[2,1-b]benzothiazole-2-amine,4-(2-imidazole) that is active on PSII by inhibiting photosynthetic oxygen evolution on the micromolar level.

Effects of Novel Photosynthetic Inhibitor [CuL]Br Complex on Photosystem II Activity in Spinach.

The effects of the novel [CuL]Br complex (L = bis{4H-1,3,5-triazino [2,1-b]benzothiazole-2-amine,4-(2-imidazole)}copper(II) bromide complex) on the photosystem II (PSII) activity of PSII membranes isolated from spinach were studied. The absence of photosynthetic oxygen evolution by PSII membranes without artificial electron acceptors, but in the presence of [CuL]Br, has shown that it is not able to act as a PSII electron acceptor. In the presence of artificial electron acceptors, [CuL]Br inhibits photosynthetic oxygen evolution.

Identification of a Phage Display-Derived Peptide Interacting with the N-Terminal Region of Factor VII Activating Protease (FSAP) Enables Characterization of Zymogen Activation.

Factor VII Activating protease (FSAP) has a protective effect in diverse disease conditions as inferred from studies in FSAP mice and humans deficient in FSAP activity due to single-nucleotide polymorphism. The zymogen form of FSAP in plasma is activated by extracellular histones that are released during tissue injury or inflammation or by positively charged surfaces. However, it is not clear whether this activation mechanism is specific and amenable to manipulation.

Cardiac involvement in multisystem inflammatory syndrome in children: single-centre experience.

Background: This study aimed to evaluate electrocardiographic and echocardiographic findings, Holter recordings of the multisystem inflammatory syndrome in children, and to identify prognostic factors for cardiac involvement.

A rare case of acute rheumatic fever with three different types of atrioventricular blocks in the same patient.

Acute rheumatic fever (ARF) is a systemic autoimmune disease that results from abnormal immune response to group A streptococcus pharyngitis. Although first-degree atrioventricular (AV) block is the most common rhythm problem associated with the disease, other conduction abnormalities also could be seen. We reported three different types of conduction defects (first-degree AV block, second-degree AV block, and complete AV block) in a 15-year-old case diagnosed with ARF.

Respiratory ß-2-Microglobulin exerts pH dependent antimicrobial activity.

The respiratory tract is a major entry site for microbial pathogens. To combat bacterial infections, the immune system has various defense mechanisms at its disposal, including antimicrobial peptides (AMPs). To search for novel AMPs from the respiratory tract, a peptide library from human broncho-alveolar-lavage (BAL) fluid was screened for antimicrobial activity by radial diffusion assays allowing the efficient detection of antibacterial activity within a small sample size.

Treatment of Permanent Junctional Reciprocating Tachycardia in a Preterm Neonate: Case Report.

Permanent junctional reciprocating tachycardia (PJRT) is most often observed in infants and children and can lead to incessant tachycardia. PJRT is usually refractory to medical treatment. Tachycardia may infrequently occur in the fetus in which case fetal tachycardia transplacental treatment should be started immediately.

Metformin decreases testicular damages following ischaemia/reperfusion injury in rats.

The effects of metformin on a testicular torsion injury in adolescent rat testis after I/R were evaluated in the present study. Forty adolescent rats were divided into five groups with eight rats per group: a control group; a sham-operated group; an ischaemia group, where torsion was applied for 4 hr and testis was examined immediately after detorsion; an I/R group, where torsion was applied for 4 hr and the testis was examined 4 hr after detorsion; and an I/R + M group, where the metformin (300 mg/kg) administration was added to the identical procedures used for the I/R group. Spermatogenesis, basal membrane integrity and cleaved caspase-3 expression were assessed.

Validation of a smartphone-based electrocardiography in the screening of QT intervals in children.

Objective: A 12-lead electrocardiography is a critical component for the screening of long QT syndrome; however, besides, an electrocardiograph, trained personnel are also necessary which limits the screening capability of conventional electrocardiographs. The development of smartphone electrocardiography technologies provides a potential alternative platform for electrocardiography screening for selective purposes such as arrhythmias and QT interval abnormalities. The aim of this pilot study was to assess the reliability of a smartphone-based electrocardiography device in the measurement of QT and corrected QT intervals in children.
