Background: Measurement of home blood pressure is an important tool for the management of hypertension. However, the validity of home devices is of concern. The Recommended Blood Pressure Devices Program of Hypertension Canada reviews and recommends blood pressure devices using international validation standards. We sought to determine the proportion of Hypertension Canada-recommended devices available for purchase in pharmacies and online.

Methods: We visited 16 community pharmacies in the Edmonton area to record the blood pressure devices they sold. We also reviewed the 50 most popular devices from online retailers (Amazon, Walmart, Best Buy, and Canadian Tire). All devices were referenced against the Recommended Blood Pressure Device Program of Hypertension Canada (www.hypertension.ca/bpdevices) to determine if the models were recommended.

Results: We reviewed 170 devices. Of those sold in pharmacies, 61 of 68 (89.7%) were Hypertension Canada-recommended devices, whereas online retailers had only 46 of 102 (45.1%) recommended devices; < 0.001.

Conclusions: Most blood pressure devices sold in pharmacies are Hypertension Canada recommended, in contrast to less than one-half from online retailers. The lack of validation of many home blood pressure devices could have important clinical implications, leading to over- or undertreatment of hypertension. Clinicians should advise patients on the importance of home blood pressure device validation and direct them to resources such as Hypertension Canada (https://hypertension.ca/public/recommended-devices) for guidance.

Is Intracranial Pressure Monitoring After Open Cranial Procedures Associated With Outcome?

J Surg Res

January 2025

Division of Trauma and Critical Care, Department of Surgery, Reading Hospital, West Reading, Pennsylvania. Electronic address:

Introduction: It is unclear if intracranial pressure monitoring (ICPM) after open cranial procedures (craniotomy or craniectomy) (OC) for traumatic brain injury is associated with mortality. We hypothesized that ICPM placed early after OC was associated with lower mortality compared to no ICPM or delayed ICPM placement.

Methods: Using 2020-2021 data from the American College of Surgeons Trauma Quality Improvement Program, patients ≥16 y from level 1 and 2 trauma centers who underwent OC were divided into two groups: ICPM placed within 72 h of OC (early) and no ICPM or ICPM placed after 72 h (none/delayed).

Rare Indocyanine-Induced Anaphylactic Shock During Deep Inferior Epigastric Artery Perforator Breast Reconstruction: A Case Report.

Ann Plast Surg

February 2025

From the Department of Plastic and Reconstructive Surgery, Ewha Womans University College of Medicine, Mokdong Hospital, Seoul, Republic of Korea.

Indocyanine green (ICG) is a water-soluble green substance that is detectable through infrared cameras and emits greenish light. Approved for medical use in the 1950s, ICG has gained prominence as a real-time visualization tool. Widely recognized as a generally safe substance, ICG is applied in diverse fields.

Background: Propofol is commonly used for pediatric MRIs to minimize patient movement. At our institution, intensivists typically administer a prophylactic 20 ml/kg saline bolus to maintain blood pressure (BP) during propofol sedation. This quality improvement project assessed whether a 10 ml/kg and a completely eliminated saline bolus are as effective as the standard 20 ml/kg bolus in completing pediatric propofol sedation and maintaining Mean Arterial Pressure (MAP).

Diagnostic properties of differing BP thresholds for adverse pregnancy outcomes in standard-risk nulliparous women: A secondary analysis of SCOPE cohort data.

PLoS Med

January 2025

Department of Women and Children's Health, School of Life Course and Population Sciences, Faculty of Life Sciences and Medicine, King's College London, London, United Kingdom.

Background: In 2017, the American College of Cardiology and American Heart Association (ACC/AHA) lowered blood pressure (BP) thresholds to define hypertension in adults outside pregnancy. If used in pregnancy, these lower thresholds may identify women at increased risk of adverse outcomes, which would be particularly useful to risk-stratify nulliparous women. In this secondary analysis of the SCOPE cohort, we asked whether, among standard-risk nulliparous women, the ACC/AHA BP categories could identify women at increased risk for adverse outcomes.
