Identifying counties at risk of high overdose mortality burden during the emerging fentanyl epidemic in the USA: a predictive statistical modelling study.

Lancet Public Health 2021 Jun 9. Epub 2021 Jun 9.

Department of Medicine, University of California, San Diego, CA, USA.

Background: The emergence of fentanyl around 2013 represented a new, deadly stage of the opioid epidemic in the USA.

Clinicopathological and immunophenotypic features of early T cell precursor acute lymphoblastic leukaemia: A flow cytometry score for the initial diagnosis.

Int J Lab Hematol 2021 Jun 11. Epub 2021 Jun 11.

Department of Hematology, SGPGIMS, Lucknow, India.

Objective: To assess the prevalence of early T precursor-acute lymphoblastic leukaemia (ETP-ALL), study its clinicopathological features and devise a 'flow score' based on immunophenotypic profiles.

Subarachnoid Hemorrhage in Mechanical Thrombectomy for Acute Ischemic Stroke: Analysis of the STRATIS Registry, Systematic Review, and Meta-Analysis.

Front Neurol 2021 25;12:663058. Epub 2021 May 25.

Division of Neuroradiology, Joint Department of Medical Imaging, Toronto Western Hospital, Toronto, ON, Canada.

The indications for mechanical thrombectomy in acute ischemic stroke continue to broaden, leading neurointerventionalists to treat vessel occlusions at increasingly distal locations farther in time from stroke onset. Accessing these smaller vessels raises the concern of iatrogenic subarachnoid hemorrhage (SAH) owing to increasing complexity in device navigation and retrieval. This study aims to determine the prevalence of SAH following mechanical thrombectomy, associated predictors, and resulting functional outcomes using a multicenter registry and compare this with a systematic review and meta-analysis of the literature.

Development and implementation of a perioperative management guide for patients with hip fracture: Health management and clinical impact.

Rev Esp Cir Ortop Traumatol 2021 Jul-Aug;65(4):294-304

Facultativo especialista de Área de Anestesiología y Reanimación, Hospital Universitario Puerta de Hierro, Majadahonda Madrid, Spain.

Introduction: Hip fracture (HF) in the elderly has a high prevalence and risk of morbidity and mortality in the short and long term. It can reduce life expectancy by almost 2 years, and require permanent socio-sanitary assistance in one in 5 patients. Its management as a process where the patient takes priority over the activities of the organisation can bring new perspectives, optimisation tools and redesign of the workflow to make it more efficient.
