Clinical and Safety Concerns With Replacing Central Venous Catheters With Midline Cathers.

OpenAI’s GPT-5 demonstration showed a patient uploading pathology reports to guide treatment decisions, though privacy implications were not addressed. We evaluated GPT-5 against 100 gastrointestinal oncology cases with tumor-board validation and found identical 85% concordance to GPT-4o, contradicting superiority claims. We recommend mandatory accuracy disclosures and regulatory oversight for AI health demonstrations to protect patient safety and privacy.

Transcranial direct current stimulation (tDCS) is a widely-used tool to induce neuroplasticity and modulate cortical function by applying weak direct current over the scalp. In this review, we first introduce the underlying mechanism of action, the brief history from discovery to clinical scientific research, electrode positioning and montages, and parameter setup of tDCS. Then, we review tDCS application in clinical samples including people with drug addiction, major depression disorder, Alzheimer's disease, as well as in children. This review covers the typical characteristics and the underlying neural mechanisms of tDCS treatment in such studies. This is followed by a discussion of safety, especially when the current intensity is increased or the stimulation duration is prolonged. Given such concerns, we provide detailed suggestions regarding safety procedures for tDCS operation. Lastly, future research directions are discussed. They include foci on the development of multi-tech combination with tDCS such as with TMS and fMRI; long-term behavioral and morphological changes; possible applications in other research domains, and more animal research to deepen the understanding of the biological and physiological mechanisms of tDCS stimulation.

Navigating the Long-Term Use of Proton Pump Inhibitors: Clinical Efficacy and Safety Concerns

To determine the basis for cardiac consultations for pediatric patients in an academic hospital setting. The activities of the cardiology consultation service were tabulated for 12 months, from July 2001 to June 2002. Patients were identified from 4 sources, ie, a monthly log of patient encounters maintained by the consultation service, encounter forms submitted to the billing office, consultation notes maintained in a central file, and a departmental list of echocardiography studies. Patients who required clearance for noncardiac surgical procedures were generally evaluated in the cardiology clinic and not by the consultation service. Patient data were obtained from consultation and echocardiography reports and from hospital computer-based records for discharge summaries for inpatient admissions, emergency department encounter summaries, and laboratory reports. For each patient, consultations were tabulated as separate encounters if they occurred on different days in the emergency department, during separate admissions, or for different clinical concerns during a single admission. A total of 2071 consultations were performed for 1724 patients. The age at the time of consultation was 6.6 +/- 9.3 years (median: 1.2 years; range: 1 day to 60.6 years). A total of 1507 patients (87.4%) had a single consultation; 217 patients (12.6%) had multiple encounters, ranging from 2 to 9, accounting for 564 consultations (27.2%). Clinical concerns included murmurs (18.5%), cardiac function (12.7%), arrhythmias (12.7%), intercurrent illnesses among cardiac patients (11.3%), cyanosis (6.3%), syndromes (5.7%), chest pain (5.2%), syncope/dizziness (4.5%), subacute endocarditis (4.4%), follow-up evaluations of fetal diagnoses (4.3%), Kawasaki disease (3.4%), cor pulmonale (3%), recent cardiac surgery or catheterization (1.6%), cerebrovascular accidents (1.2%), and miscellaneous conditions. Four diagnoses accounted for 91% of murmur evaluations, ie, patent ductus arteriosus, ventricular septal defects, innocent murmurs, and pulmonary branch murmur of infancy. The most common murmur diagnosis in the neonatal intensive care unit was patent ductus arteriosus (68%), in the well-child nursery was ventricular septal defect (64%), and on the medical ward was innocent murmur (62%). The most common basis for evaluation of function was oncologic disease. Among patients evaluated for function, there were 3 new diagnoses of structural congenital heart disease, all involving neonates with aortic arch obstruction. Approximately two-thirds of arrhythmias were supraventricular in origin. The most common arrhythmias requiring treatment were supraventricular tachycardia and atrial flutter/fibrillation, the latter occurring mainly among older patients with structural heart disease. Diagnoses made with fetal echocardiography accounted for 14.3% of newborn consultations and included 83% of patients with cyanotic cardiac disease. Three syndromes accounted for 57% of consultations for this indication, ie, VACTERL association (vertebral anomalies, anal atresia, congenital heart disease, tracheoesophageal fistula, renal abnormality, and limb anomalies), trisomy 21, and infant of diabetic mother. Chest pain and syncope/dizziness were frequently evaluated in the emergency department and, in this setting, accounted for 13 and 10% of all evaluations and 19 and 25% of evaluations for new patients, respectively. For patients evaluated for chest pain, the most common basis was musculoskeletal/costochondritic (42%) or idiopathic (22%). There was a cardiac or pericardial basis in 11% of cases; these patients either had known heart disease associated with this complication or systemic symptoms, abnormal cardiac auscultatory findings, and electrocardiographic features of pericarditis. Syncope/dizziness most commonly had a vasovagal (50.5%) or orthostatic (24.7%) basis. There was a cardiac basis in 5.4% of cases; these patients were more likely to have symptoms associated with exercise. Although endocarditis was a frequent clinical concern (91 patients), only 3 cases were identified, involving 2 patients with structural heart disease and 1 neonate with an indwelling intracardiac catheter. Two other patients had central venous lines, intravascular thrombus, and fungemia. Kawasaki disease was the most common acquired condition leading to consultation. Cor pulmonale was most commonly screened among patients with congenital diaphragmatic hernia, chronic lung disease of prematurity, pneumonitis, reactive airway disease, or cystic fibrosis. Patients with recent cardiac surgery or cardiac catheterization typically had postpericardiotomy syndrome or complications associated with vascular access. Approximately 20% of cases of cerebrovascular accidents had a cardiac basis. Although a variety of conditions were assessed, some were encountered more frequently. Future educational curricula developed for cardiac training of pediatric residents should appropriately emphasize conditions necessitating consultation.

Paediatric hospital-associated venous thromboembolism is a leading quality and safety concern at children's hospitals. The aim of this study was to determine risk factors for hospital-associated venous thromboembolism in critically ill children following cardiothoracic surgery or therapeutic cardiac catheterisation. We conducted a retrospective, case-control study of children admitted to the cardiovascular intensive care unit at Johns Hopkins All Children's Hospital (St. Petersburg, Florida, United States of America) from 2006 to 2013. Hospital-associated venous thromboembolism cases were identified based on ICD-9 discharge codes and validated using radiological record review. We randomly selected two contemporaneous cardiovascular intensive care unit controls without hospital-associated venous thromboembolism for each hospital-associated venous thromboembolism case, and limited the study population to patients who had undergone cardiothoracic surgery or therapeutic cardiac catheterisation. Odds ratios and 95% confidence intervals for associations between putative risk factors and hospital-associated venous thromboembolism were determined using univariate and multivariate logistic regression. Among 2718 admissions to the cardiovascular intensive care unit during the study period, 65 met the criteria for hospital-associated venous thromboembolism (occurrence rate, 2%). Restriction to cases and controls having undergone the procedures of interest yielded a final study population of 57 hospital-associated venous thromboembolism cases and 76 controls. In a multiple logistic regression model, major infection (odds ratio=5.77, 95% confidence interval=1.06-31.4), age ⩽1 year (odds ratio=6.75, 95% confidence interval=1.13-160), and central venous catheterisation (odds ratio=7.36, 95% confidence interval=1.13-47.8) were found to be statistically significant independent risk factors for hospital-associated venous thromboembolism in these children. Patients with all three factors had a markedly increased post-test probability of having hospital-associated venous thromboembolism. Major infection, infancy, and central venous catheterisation are independent risk factors for hospital-associated venous thromboembolism in critically ill children following cardiothoracic surgery or cardiac catheter-based intervention, which, in combination, define a high-risk group for hospital-associated venous thromboembolism.

Hospital-acquired infections (HAI) reflect as a major global safety concern for both patients and health-care professionals. These infections could be in the form of cross-infection, endogenous infection and environmental Infection. Over 80% of these infections are related to devices’ utilization needed for patients’ life support. Methods show this is an observational and cross-sectional study, to identify the microorganism and determine the potential source of transmitting of hospital acquired infection by routine devices in adult ICU. The samples were collected using Amies transport media; three swabs were taken from the surfaces of indwelling urinary catheter, mechanical ventilation device and central venous catheter used from every twelve patients. The samples were cultured and analyzed by using microbiologic technique. Finally, all samples analyzed by MicroScan WalkAway 96 pulse. Results showing the most bacteria isolated are “Klebsiella pneumonia” (18.37%), “Acinetobacter baumannii” (11.48%), “Staphylococcus epidermidis” (4.59%), “Staphylococcus haemolyticus” (4.59%), “E. coli” (4.59%), “Serratia marcescens” (2.3%), “Pseudomonas luteola” (2.3%), “Kocurio kristinae” (2.3%) and “Photorhabdus luminscens” (2.3%). This study detects a high contamination of routine devices and resistant organisms. In the end it is recommended that effective infection control practices and effective strategies to control antibiotic-resistant bacteria should be applied.
