A scoping review investigating the perspectives of people with mild to moderate intellectual disabilities on experiences of cyberbullying victimisation and its subtypes.

This scoping review examines cyberbullying victimisation in people with mild to moderate intellectual disabilities, focusing on specific types of cyberbullying behaviours, such as flaming, harassment, and stalking. A five-stage review of empirical research was conducted using 15 electronic databases, covering publications from October 1969 to January 2024. Twelve studies were selected, reporting cyberbullying victimisation rates ranging from 5% to 64%. Harassment was the most common behaviour experienced. However, flaming, cyber-stalking, griefing, and shaming have not been thoroughly investigated. The impact and coping strategies, including support mechanisms, also lack research. Further investigation is needed to understand the various types of cyberbullying experienced by people with intellectual disabilities and to develop coping and resilience strategies. Recommendations for future research and practice are provided.

Prescribing an automated external defibrillator for children at increased risk of sudden arrhythmic death.

BACKGROUND: Automated external defibrillators can be life-saving in out-of-hospital cardiac arrest. OBJECTIVE: Our aim was to review our experience of prescribing automated external defibrillators for children at increased risk of sudden arrhythmic death. METHODS: We reviewed all automated external defibrillators issued by the Scottish Paediatric Cardiac Electrophysiology Service from 2005 to 2015. All parents were given resuscitation training according to the Paediatric Resuscitation Guidelines, including the use of the automated external defibrillator. RESULTS: A total of 36 automated external defibrillators were issued to 36 families for 44 children (27 male). The mean age at issue was 8.8 years. Diagnoses at issue included long QT syndrome (50%), broad complex tachycardia (14%), hypertrophic cardiomyopathy (11%), and catecholaminergic polymorphic ventricular tachycardia (9%). During the study period, the automated external defibrillator was used in four (9%) children, and in all four the automated external defibrillator correctly discriminated between a shockable rhythm - polymorphic ventricular tachycardia/ventricular fibrillation in three patients with one or more shocks delivered - and non-shockable rhythm - sinus rhythm in one patient. Of the three children, two of them who received one or more shocks for ventricular fibrillation/polymorphic ventricular tachycardia survived, but one died as a result of recurrent torsades de pointes. There were no other deaths. CONCLUSION: Parents can be taught to recognise cardiac arrest, apply resuscitation skills, and use an automated external defibrillator. Prescribing an automated external defibrillator should be considered for children at increased risk of sudden arrhythmic death, especially where the risk/benefit ratio of an implantable defibrillator is unclear or delay to defibrillator implantation is deemed necessary.

Association of leukocyte-depleted blood transfusions with infectious complications after cardiac surgery.

BACKGROUND: To test the hypothesis that leukocyte-mediated immunosuppression may contribute to postoperative infections after blood transfusions, we compared the incidence of postoperative infections in patients undergoing elective coronary artery bypass graft (CABG) surgery who received either leukocyte-depleted (LD-RBCC) or non-LD transfusions of red blood cell concentrates (RBCC) within 48 h of surgery. MATERIALS AND METHODS: Data for all primary elective CABG patients between 1995 and 1998 who received allogeneic RBCC transfusions in the first 48 h after surgery were collected. Patients were divided into two groups (group LD: LD-RBCC transfusions only; group non-LD: non-LD-RBCC transfusions only were excluded). Patients who received a combination of LD and non-LD-RBCC transfusions, or any blood products other than RBCC were excluded. Infectious complications recorded included pneumonia, acute respiratory distress syndrome, mediastinitis, leg wound/sternal wound infection, nosocomial infection, catheter-related infection, urinary tract infection, decubitus ulcers, and bacteremia/fungemia. RESULTS: One hundred forty-two patients received only LD-RBCC transfusions, and 1,765 patients received only non-LD-RBCC transfusions. Power analysis demonstrated that the sample size attained 80% power to detect an odds ratio of 2.1 at a significance level of p < 0.05. Infection rates were not significantly different between the non-LD and LD groups (7.57% vs. 9.52%, p = 0.40). Leukocyte depletion status of RBCC transfusions was not a predictor of infectious complications (p = 0.73). However, total units of RBCC received was highly associated with increased infection (p = 0.0001). CONCLUSIONS: No association between postoperative infections and the use of leukocyte-depleted blood was identified. However, an increased incidence of postoperative infections was observed to be associated with blood transfusions in general.

The association of patent foramen ovale and atrial fibrillation after coronary artery bypass graft surgery.

UNLABELLED: Atrial fibrillation (AF) is associated with considerable morbidity and increased resource utilization after coronary artery bypass graft surgery. In this study, we sought to determine whether patent foramen ovale (PFO) and atrial septal aneurysm are associated with an increased risk of postoperative AF in this patient population. We performed a database study on 1008 patients undergoing primary coronary artery bypass graft surgery. All patients were assessed for the development of postoperative AF from the day of surgery to hospital discharge. Atrial septal defects were identified during comprehensive intraoperative transesophageal echocardiographic examination. Postoperative AF was present in 124 (12.3%) patients. Patients with AF were significantly older and had a more frequent incidence of preoperative congestive heart failure, longer cross-clamp time, and prolonged hospital length of stay. PFO was present in 72 (7.1%) and atrial septal aneurysm in 23 (2.3%) patients. In these patients, postoperative AF was present in 14 (19.4%) patients with PFO and 8 (34.8%) patients with atrial septal aneurysm. Multivariate logistic regression analysis identified that PFO (odds ratio [OR], 1.95; 1.007-3.778; P = 0.047), age (OR, 1.03; 1.015-1.053; P = 0.0004), and history of congestive heart failure (OR, 2.55; 1.671-3.900; P < 0.0001) were predictive of postoperative AF. IMPLICATIONS: The presence of patent foramen ovale is associated with new-onset postoperative atrial fibrillation after coronary artery bypass graft surgery. This finding requires further validation in future prospective trials.

Predictors of inotrope use during separation from cardiopulmonary bypass.

OBJECTIVE: To identify the demographic, clinical, and echocardiographic features that predict the use of inotropic support at separation from cardiopulmonary bypass (CPB). DESIGN: Retrospective study of consecutive patients undergoing coronary artery bypass graft (CABG) surgery. SETTING: Referral center for cardiothoracic surgery at a university hospital. PARTICIPANTS: One thousand nine patients undergoing either CABG or combined CABG and valve surgery with CPB in whom an intraoperative transesophageal echocardiography (TEE) examination was performed. INTERVENTIONS: Inotropic support was defined as the use of dopamine >/=5 microg/kg/min; any dose of epinephrine, norepinephrine, dobutamine, and milrinone; or the insertion of an IABP during separation from CPB. Support was implemented by the anesthesia care team as clinically indicated. Comprehensive TEE examinations were conducted before CPB in all patients according to published guidelines and subsequently reviewed by a single, independent operator. MEASUREMENTS AND MAIN RESULTS: Inotropic support was used in a total of 394 patients (39%) at separation from CPB. The study identified 6 significant, independent predictors of inotrope use: (1) Wall Motion Score Index, (2) combined CABG and mitral valve repair or replacement surgery, (3) left ventricular ejection fraction <35%, (4) reoperation, (5) moderate-to-severe mitral regurgitation, and (6) aortic cross-clamp time. CONCLUSIONS: Incorporating data from a comprehensive intraoperative TEE examination, the authors identified 6 reproducible factors that independently predict the use of inotropic support at separation from CPB.
