Background: Wearable electrocardiography (ECG) devices such as smartwatches offer a novel means for detecting cardiac arrhythmias, particularly atrial fibrillation (AF), and ST-segment abnormalities. Their role in complementing or replacing traditional ECG methods is being increasingly investigated. Objective: To evaluate the diagnostic performance (sensitivity, specificity) of wearable ECG devices in detecting AF and ST-segment changes, compared to 12-lead ECG as the gold standard. Methods: A systematic search was performed in PubMed, Scopus, and additionally, the SpringerLink platform was consulted up to June 2025, targeting open-access, English-language clinical studies from the last five years. Inclusion criteria: adult population, use of a wearable ECG device, 12-lead ECG comparator, and diagnostic accuracy reporting. Out of 145 records, 5 studies met the inclusion criteria. The systematic review protocol was not prospectively registered in PROSPERO due to the limited number of available studies and the exploratory nature of the topic, which focused on the most recent clinical evaluations of wearable ECG devices. However, the review strictly adhered to the PRISMA 2020 guidelines for systematic reviews to ensure methodological transparency and reproducibility. Results: Five studies encompassing a total of 1133 participants were incorporated into the analysis. Devices evaluated included Apple Watch (Series 4–6), KardiaMobile 6L, FibriCheck, Preventicus, and HUAMI dynamic ECG. Sensitivity ranged from 83% to 100%, and specificity from 79% to 100%. Algorithm improvements and repeated measurements significantly reduced inconclusive recordings. Multichannel ECG methods using smartwatches showed high agreement with 12-lead ECG in ST-elevation myocardial infarction detection. Conclusions: Wearable ECG devices demonstrate high diagnostic performance for AF and ST-segment abnormalities, especially in supervised environments. However, inconclusive recordings and algorithm limitations remain barriers to widespread clinical use. Real-world validation and algorithm refinement are needed for broader adoption.

Background: Venous blood collection in pediatric patients is a critical procedure for diagnostic and monitoring purposes, yet it remains considerably more challenging than in adults. Factors such as small vein size, limited cooperation, and heightened sensitivity to pain contribute to technical difficulties and increased error rates. Objectives: This mini-review aims to provide a concise synthesis of current clinical practices and emerging technologies that support safer, more efficient venipuncture in children. Results: Key findings include the anatomical and procedural considerations relevant to pediatric venipuncture, age-specific recommendations for technique and positioning, as well as evidence-based strategies to reduce pain and anxiety. Common preanalytical errors, particularly hemolysis and insufficient sample volumes, are also addressed, along with their implications for clinical outcomes. Recent advances in medical digitalization, including the use of venous ultrasound, near-infrared projection, and transillumination, offer valuable support in overcoming procedural challenges. These technologies are not meant to replace human expertise but to complement it, improving vein visualization and increasing first-attempt success rates when integrated into a child-centered approach. Conclusions: Venous blood collection in pediatric patients requires a delicate balance between technical proficiency and human-centered care. Emphasis is placed on the importance of a child-centered approach, combining technical skill with empathy and clear communication. Enhancing the quality and safety of venous sampling in children requires not only training and standardization, but also a deeper understanding of the psychological dimensions involved in pediatric care.

Background and Objectives: The incidence and prevalence of cancers are increasing worldwide, with special emphasis placed on prevention, early detection, and the development of new therapeutic strategies that strongly impact patient outcomes. Limited data are available about emergency care’s role in treating patients with cancer. This study aims to determine the burden of end-stage and first-time diagnosis of cancer on emergency care in a high-turnover emergency care center. Materials and Methods: A retrospective observational study was conducted to identify patients requesting emergent aid for cancer-related symptoms in the Emergency Department of “St. Spiridon” Hospital from Iasi (Romania) between 1 October 2022 and 30 September 2023. The proportion and demographic characteristics of end-stage patients and those who received a first-time diagnosis during the emergency visit were evaluated. Risk analysis was performed to understand these patients’ care needs (such as medical care, surgical care, specialty consults, intensive care, ward admission, and other hospital transfers) and immediate care outcomes (such as in-hospital mortality and home discharge). Results: 2318 patients with cancer requested emergent care (patient presentation rate of 3.08%), of which 444 (19.15%) were diagnosed for the first time, and 616 (26.57%) were at the end-stage. First-time diagnosed patients had a significantly different distribution of cancer types (p < 0.001), were more likely to need any form of medical care, to require a specialty consultation, or to be admitted to a ward (OR 2.65, 95% CI: 2.12–3.32; p < 0.001; OR 3.28, 95% CI: 2.48–4.35, p < 0.001; OR 2.09, 95% CI: 1.70–2.59; p < 0.001, respectively) but were less severe, while end-stage patients were more likely to address repeatedly to the emergency room (OR 1.86, 95% CI: 1.32–2.59; p = 0.001) and had higher odds of needing intensive care, assisted ventilation and death (OR-4.63, 95% CI: 1.10–19.45, p = 0.04; OR 2.59, 95% CI: 1.57–4.28; p < 0.001, and OR 4.06, 95% CI: 1.73–9.54; p = 0.001, respectively). Conclusions: The emergency department often carries the weight of diagnosing patients with cancer and treating patients with end-stage disease. These data highlight the importance of prehospital care, particularly for cancer screening and palliative care, and the importance of fostering multidisciplinary collaboration in the emergency room with oncologists, geriatricians, and palliative care specialists to improve patient outcomes.

Background and Objectives: The incidence and prevalence of cancers are increasing worldwide, with special emphasis placed on prevention, early detection, and the development of new therapeutic strategies that strongly impact patient outcomes. Limited data is available about emergency care's role in diagnosing cancer patients. This study aims to determine the prevalence of novel cancer diagnoses in the emergency department and identify their therapeutic needs. Materials and Methods: A retrospective observational study was conducted to identify patients diagnosed with cancer in the Emergency Department of “St. Spiridon” Hospital between 1st October 2022 and 30th September 2023. The percentage of patients who received a first-time diagnosis during an emergency visit was determined. Clinical factors, such as gender, age, localization of cancer, and the need for hospitalization, were evaluated in relation to the emergency presentation. Results: The rate of cancer presentations to the emergency department was 3.08%. 2318 patients with cancer requested emergent care in the evaluated period, of which 444 (19.15%) were diagnosed for the first time. These patients had a significantly different distribution of cancer types (p<0.001), were more likely to need any form of medical care, to require a specialty consultation, or to be admitted to a ward (OR 2.65, 95% CI: 2.12-3.32; P < 0.001, P < 0.001; OR 3.28, 95% CI: 2.48-4.35, P < 0.001; OR 2.09, 95% CI: 1.70-2.59, respectively). There was a slight increase in the odds of death for de novo cases (OR-1.01, 95% CI 1.01-1.02, p = 0.01). Conclusions: A significant number of patients receive a first-time cancer diagnosis in the emergency department. Neoplasms can present symptoms similar to those of other conditions, making diagnosis challenging in the busy and resource-limited environment of the emergency department, where time constraints can limit thorough patient evaluation. A multidisciplinary approach is needed to manage these cases.
