Exertional Heat Illness-From Identifying Heat Rash to Treating Heat Stroke.

Heat-related illness commonly affects adolescent patients, especially as summer approaches and global temperature extremes worsen. Basic counseling on sunburn prevention can decrease the risk for future malignancies, and rapidly preventing, identifying, and treating heat stroke can prevent severe morbidity and mortality. This article will review the epidemiology of exertional heat-related illness and the variations in presentations and pathology, from heat rash and sunburn to heat exhaustion and heat stroke.

The wrist is not the brain: Estimation of sleep by clinical and consumer wearable actigraphy devices is impacted by multiple patient- and device-specific factors.

Clinical actigraphy devices provide adequate estimates of some sleep measures across large groups. In practice, providers are asked to apply clinical or consumer wearable data to individual patient assessments. Inter-individual variability in device performance will impact such patient-specific interpretation.

A decade of countering bioterrorism: incremental progress, fundamental failings.

The fear and disruption caused by the 2001 anthrax attacks understandably led Americans to seek enhanced biodefenses. However, the path followed since those attacks has left the country inadequately prepared to face further risks from biological attacks. Why has security against these threats been only partially achieved? This article suggests that our responses over the past decade can be sorted into 4 levels in order of increasing difficulty.

Lidars: a key component of urban biodefense.

A biological aerosol attack in a city could infect tens of thousands of people. In the absence of announcements by the attacker or detection by present point detection systems, victims would be unaware of their exposure prior to developing symptoms. Since infections are most effectively countered before the onset of symptoms, detection technologies that provide early awareness of an attack should be given high priority.
