Persons who have experienced a prior myocardial infarction (MI) are at a greater risk of experiencing a secondary event. External factors, such as stress, can cause transient hypertension, further increasing cardiovascular disease risk. However, challenges to monitoring stress-induced hypertension include obtrusiveness of monitoring devices, unknown validity in high-risk populations, and unsubstantiated sensitivity in stressful environments.

Department of Regeneration and Medicine, Research Institute for Radiation Biology and Medicine, Hiroshima University, Hiroshima, Japan.
Article Synopsis
- First-degree atrioventricular block (AVB) is common in ECG findings and has been linked to vascular dysfunction, however, its specific relationship with vascular function was unclear.
- The study analyzed the PR interval's association with vascular function in 2220 participants, comparing 106 with first-degree AVB and 1241 with normal PR intervals.
- Results showed that individuals with AVB had significantly lower endothelium-dependent vasodilation (FMD) but not endothelium-independent vasodilation (NID), suggesting that first-degree AVB may indicate impaired vascular health rather than just being an ECG anomaly.
Iatrogenic nerve injury during upper limb surgery (excluding the hand).

Nerve injury is the most feared complication of upper limb surgery. In about 17% of cases, the injury is iatrogenic and the potential for recovery is poor. In this context, patients file for compensation in about a quarter of cases.

Article Synopsis
- Traumatic brachial plexus injury severely affects arm function, but myoelectric exoskeletons can help restore elbow flexion.
- The study assessed whether adults with these injuries, who have undergone surgical reconstruction of elbow flexors, can effectively control myoelectric exoskeletons using their muscle signals.
- Results show that while a single activation threshold for controlling the exoskeleton is feasible, individual signal variability and a necessary 'settle-time' after muscle contraction must be considered for effective operation.
Common sports-related nerve injuries seen by the electrodiagnostic medical consultant.
Muscle Nerve
November 2024
Department of Medicine, Division of Physical Medicine and Rehabilitation, University of Toronto, Toronto, Ontario, Canada.
The high physiologic demands of sports create dynamic stress on joints, soft tissues, and nerves which may lead to injuries in the athlete. Electrodiagnostic (EDx) assessment is essential to identify the correct diagnosis, localization, and prognosis, to guide management of sports-related neuropathies. A comprehensive review was performed to provide the EDx medical consultant with a practical approach to the common peripheral nerve disorders seen in athletes.
