A 3 MHz Low-Error Adaptive Howland Current Source for High-Frequency Bioimpedance Applications.

Bioimpedance is a diagnostic sensing method used in medical applications, ranging from body composition assessment to detecting skin cancer. Commonly, discrete-component (and at times integrated) circuit variants of the Howland Current Source (HCS) topology are employed for injection of an AC current. Ideally, its amplitude should remain within 1% of its nominal value across a frequency range, and that nominal value should be programmable.

Multi-Modal Spectroscopic Assessment of Skin Hydration.

Human skin acts as a protective barrier, preserving bodily functions and regulating water loss. Disruption to the skin barrier can lead to skin conditions and diseases, emphasizing the need for skin hydration monitoring. The gold-standard sensing method for assessing skin hydration is the Corneometer, monitoring the skin's electrical properties.

Relationship between Glycemic Levels and Treatment Outcome among Critically Ill Children admitted into Emergency Room in Enugu.

Background: Critically ill children are those in need of immediate attention on arrival to an emergency room. The importance of glycemic level measurement as well as maintaining the patency of the airway, effective breathing and circulation cannot be overemphasied. It has been highlighted that the peak hyperglycemia and hypoglycemia predict poor prognosis, longer lengths of hospital stay and higher mortality.

Danger Signs of Childhood Pneumonia: Caregiver Awareness and Care Seeking Behavior in a Developing Country.

Background. Efforts to reduce child mortality especially in Africa must as a necessity aim to decrease mortality due to pneumonia. To achieve this, preventive strategies such as expanding vaccination coverage are key.

Delays in healthcare delivery to sick neonates in Enugu South-East Nigeria: an analysis of causes and effects.

Background: In most parts of the world, neonatal mortality rates have shown a slower decline when compared with under-5 mortality decline. A sick newborn can die within minutes if there is a delay in presentation, thus early diagnosis and treatment are essential for the survival of a critically ill newborn. This study investigated factors responsible for delays in healthcare services for the sick newborn and maternal socio-demographic variables that influence these delays in Enugu, South-East Nigeria.
