This study investigates the relationship between ADHD symptom severity, metacognition, problematic social media use, and cyberbullying/cybervictimization in treatment-naïve adolescents. Understanding these relationships is vital for enhancing ADHD intervention strategies. Using a cross-sectional design, 97 adolescents meeting DSM-5 criteria for ADHD without any comorbidity and 97 healthy controls were assessed.

It catalyzes two chemical reactions: water oxidation to molecular oxygen and plastoquinone reduction. Coupling of electron and proton transfer is crucial for efficiency; however, the molecular basis of these processes remains speculative owing to uncertain water binding sites and the lack of experimentally determined hydrogen positions.

Previous studies have shown that PASC impacts 10% of SARS-CoV-2 infected patients of which 50-70% are hospitalised. It has also been shown that 10-12% of those vaccinated against COVID-19 were affected by PASC and its complications.

Child abuse and neglect includes any behavior that harms the child or hinders the child's development. The aim of this study was to determine the demographic and clinical characteristics of patients with suspected child abuse or neglect in the pediatric emergency department. Between July 2017 and July 2022, patients admitted to our pediatric emergency department and consulted to the medical social services unit with a preliminary diagnosis of neglect and/or abuse were retrospectively scanned through the registry system.

The ongoing identification of the binding sites and modes of the two water-derived substrate oxygens ('substrate waters') in the various intermediates (S states, i = 0, 1, 2, 3, 4) that the water-splitting tetra-manganese calcium penta-oxygen (MnCaO) cluster attains during the reaction cycle provides central information towards resolving the unique chemistry of biological water oxidation. Mass spectrometric measurements of single- and double-labeled dioxygen species after various incubation times of PSII with HO provide insight into the substrate binding modes and sites via determination of exchange rates.

Mindfulness was found to directly impact the severity of depressive symptoms, by recognizing negative cognitions and dysfunctional reactions. The aims of this study were to compare ER and mindfulness levels between MDD patients and healthy controls (HCs), as well as to examine whether ER and mindfulness are related to symptom severity in MDD patients.

Methods: Patients aged one month to 18 years who underwent neuroimaging with a preliminary diagnosis of intracranial pathology requiring emergency surgery and symptom duration less than one month were included in the study. Patients were divided into three groups according to their definitive diagnosis as neurosurgical emergencies, neurological emergencies, and nonurgents.
Background: Disrupted metacognition is implicated in development and maintenance of negative symptoms, but more fine-grained analyses would inform precise treatment targeting for individual negative symptoms.
Aims: This systematic review identifies and examines datasets that test whether specific metacognitive capacities distinctly influence negative symptoms.
Materials & Methods: PsycINFO, EMBASE, Medline and Cochrane Library databases plus hand searching of relevant articles, journals and grey literature identified quantitative research investigating negative symptoms and metacognition in adults aged 16+ with psychosis.
Introduction: Cardiological emergencies are reported to constitute almost 15% of all emergency department visits. This study aimed to characterize the main signs and symptoms of the infants that necessitated pediatric cardiology consultation and to analyze the characteristics of patients diagnosed with a cardiological disorder.
Material And Methods: Patients aged 1 month to 1 year who were consulted to the pediatric cardiology service during a 4-year period were retrospectively evaluated.
Background: Mexiletine, a class IB antiarrhythmic, is a structural analog of lidocaine. Our knowledge of mexiletine overdose is based on lidocaine overdose reports. Only a few cases of mexiletine overdose have been reported, including fatal overdoses.

The reaction takes place in photosystem II, where the MnCaO cluster first stores four oxidizing equivalents, the S to S intermediate states in the Kok cycle, sequentially generated by photochemical charge separations in the reaction center and then catalyzes the O-O bond formation chemistry. Here, we report room temperature snapshots by serial femtosecond X-ray crystallography to provide structural insights into the final reaction step of Kok's photosynthetic water oxidation cycle, the S→[S]→S transition where O is formed and Kok's water oxidation clock is reset.

Recent studies have shown a growing vulnerability for cyberbullying and cybervictimization, particularly in the adolescent population. We argue that dysfunctional metacognitions, which have been found to be prominent in various psychiatric disorders, may also play a role in predicting cyberbullying and cybervictimization over and above a variety of established factors including daily Internet use, social media use, depression and anxiety.

Method: Patients with a history of balance and gait coordination disorder and clinically diagnosed as acute ataxia in pediatric emergency department were included in the study. As a result of final diagnosis, the characteristics of patients with and without clinically urgent neurological pathology (CUNP) were compared.
The problematic use of social networking sites (SNS) is associated with several psychiatric disorders. This behavior closely resembles addiction in terms of neurological basis and behavioral patterns. Nevertheless, successful intervention strategies and the etiology of problematic SNS use are not yet thoroughly investigated.

Methods: Patients with ICD-10 code W54 (contact with dog) and W55 (contact with other mammals) between March 1, 2017, and July 1, 2021, were included in the study. Demographic characteristics of the patients, type of contacted animal, wound characteristics (muscle involvement, soft tissue defect, vascular injury, type of nerve injury, and Lackmann's classification), wound care measurements, tetanus prophylaxis, administration of rabies immunoglobulin and antibiotics, location of the injury, existing fractures, suturing, splinting, surgical consultations and hospitalization status were recorded.
Objectives: Foreign body aspiration (FBA) has a wide clinical spectrum, patients may be asymptomatic or present with cardiopulmonary arrest. Radiological imaging methods are used in addition to history and physical examination findings for certain diagnosis. Lung ultrasonography (LUS), whose usage area is increasing year by year, can be included in these.

The prognostic value of systemic immune-inflammatory index (SII), an innovate biomarker of inflammation, in fulminant myocarditis in children has not been assessed. This study aims to (1) determine the effect of SII and other inflammatory markers on the prognosis of patients with myocarditis, and (2) characterize other factors affecting adverse outcomes in myocarditis.

Materials And Methods: We conducted a retrospective analysis of 7648 injury-related pediatric emergency department visits between March 11 and June 30, 2018, 2019, and 2020, and com- pared the total number of visits, triage levels, distributions of injury mechanisms, and admission rates during the pandemic in 2020 to the same period in 2018 and 2019.
Aim: SARS-CoV-2 infection in children is generally asymptomatic or mild; however, it can lead to a life-threatening clinical condition, multisystem inflammatory syndrome in children (MIS-C), days or weeks after the infection. Increased intestinal permeability isa possible triggering factor at the onset of the hyperinflammation associated with MIS-C. Zonulin and claudin-5 are involved in intestinal permeability.
