Background: Advanced cardiovascular life support (ACLS) for cardiac arrest is a cornerstone of emergency care and yet remains poorly studied in low- and middle-income countries. We characterised the clinical epidemiology and outcomes of cardiac arrest and ACLS in an ED in central Haiti, a lower middle-income country with a nascent emergency care system.
Methods: We conducted a prospective observational study of adult and paediatric patients who suffered cardiac arrest in an academic hospital ED in central Haiti from January 2019 to August 2020.
Background: The placement of breast implants in a prepectoral plane has become increasingly popular in breast reconstruction, although data on how this affects radiation delivery in women with breast cancer are limited. This study aimed to assess the dosimetric differences in radiation plans for immediate breast reconstruction between prepectoral and subpectoral implants.
Methods: In this study, a retrospective review and dosimetric analysis of patients with breast cancer who underwent immediate implant-based reconstruction and postmastectomy radiation therapy (PMRT) were performed.
The Particle Time of Flight (PTOF) diagnostic is a chemical vapor deposition diamond-based detector and is the only diagnostic for measuring nuclear bang times of low yield (<1013) shots on the National Ignition Facility. Recently, a comprehensive study of detector impulse responses revealed certain detectors with very fast and consistent impulse responses with a rise time of <50 ps, enabling low yield burn history measurements. At the current standoff of 50 cm, this measurement is possible with fast 14 MeV neutrons from deuterium-tritium (DT) fusion plasmas.

The objective of this study was to evaluate the effect of allogeneic haematopoietic stem-cell transplantation (HSCT) in a cohort of children with sJIA-LD.
Methods: This international, retrospective cohort study was performed in nine hospitals across the USA and Europe in children with sJIA-LD who had received allogeneic HSCT.
Article Synopsis
- The syndrome of undifferentiated recurrent fevers (SURF) is marked by recurring fevers and inflammation without a clear hereditary cause, differing from PFAPA syndrome.
- A study involving 46 patients highlighted that those with SURF often exhibited more skin rashes and joint pain, while having fewer cases of throat infections and swollen lymph nodes compared to PFAPA patients.
- The results also indicated that patients with SURF showed higher levels of pro-inflammatory cytokines and frequently needed biologic treatments, suggesting distinct clinical features and potential genetic factors that warrant further investigation.
