Many Internet of Things (IoT) applications are emerging and evolving rapidly thanks to widespread open-source hardware platforms. Most of the high-end open-source IoT platforms include built-in peripherals, such as the universal asynchronous receiver and transmitter (UART), pulse width modulation (PWM), general purpose input output (GPIO) ports and timers, and have enough computation power to run embedded operating systems such as Linux. However, each IoT platform has its own way of configuring peripherals, and it is difficult for programmers or users to configure the same peripheral on a different platform.

Fire hazard monitoring and evacuation for building environments is a novel application area for the deployment of wireless sensor networks. In this context, adaptive routing is essential in order to ensure safe and timely data delivery in building evacuation and fire fighting resource applications. Existing routing mechanisms for wireless sensor networks are not well suited for building fires, especially as they do not consider critical and dynamic network scenarios.

Objective: We investigated factors associated with isolated mental delay in infants weighing < 1250 g at birth.

Study Design: With a case-control design, matching variables for 40 cases included gestation, birth weight, sex, grade of intraventricular hemorrhage, and socioeconomic status. Case subjects had a mental developmental index < 70, and controls had a mental developmental index > or = 85, according to the Bayley Scales of Infant Development II at 18 months' corrected age.

Apnea of prematurity (AOP) is frequently managed with nasal continuous positive airway pressure (NCPAP). Nasal cannula (NC) are used at low flows (<0.5 L/min) to deliver supplemental oxygen to neonates.

Despite widespread immunization against Bordetella pertussis, whooping cough remains potentially fatal in susceptible populations such as neonates. A case of neonatal pertussis with severe pulmonary hypertension (PH) requiring extracorporal membrane oxygenation (ECMO) is described. PH associated with pertussis severe enough to require ECMO is frequently irreversible and associated with a poor prognosis.
