BACKGROUND Injury is a major public health problem in many developing countries. Due to limitations of vital registry and health service data, surveys are an important tool to obtain information about injury in these countries. The value of such surveys can be limited by incomplete recall. The most appropriate recall period to use in surveys on injury in developing countries has not been well a...

Spectrophotometric observations of the gravitationally microlensed quasar Q2237+0305 during a High Magnification Event (HME) is potentially a very powerful tool for probing the structure of the quasars accretion disc on scales of ∼ 10 arc seconds. In cases where the HME is produced by a single caustic (SHME), microlensing induced changes in the spectrum during the event may be used to directly ...

Calcified seaweed (CS) based products have been proposed as an alternative ruminal pH buffer to sodium bicarbonate. It has reported that magnesium can aid in control too, especially those natural marine forms. We assessed the rumen capacity and milk production composition of two CS: Acid Buf (AB) compared with M12 (a enriched CS) on grazing dairy cows a replicated Latin Square design involving ...

Extreme weather events are related to low birth weight. Monitoring this relationship in the context of climate change has a wide range of public health implications, as birth weight is a key indicator of many life course health outcomes, and climate change increases both frequency and intensity of extreme weather events. However, most birth weight data are not available with sufficient spatial ...

Although monitoring of vascular accesses by physical examination is nearly as sensitive as surveillance measurements by vascular access pressure when performed by examiners, the frequency of examinations is limited by time. We developed intravascular access pressure surveillance as a surrogate to physical examination. Using real-time data from hemodialysis machines, we derived intravascular acc...
