Annually, 1 December is not only known for World AIDS Day celebrations but, for most South Africans, it is time to start preparing for a long-awaited summer break. The year 2012 was marked by quite a few major successes on the nursing front. We as nurses can be proud of the work that the Ministerial Task Team (MTT) completed, and 2013 will be the year of implementing the outcomes of the MTT.

Iron, one of the most abundant metals on earth, is essential to most life forms and to normal human physiology. Iron is an integral part of many proteins and enzymes that maintain good health. A deficiency of iron limits oxygen delivery to cells, resulting in fatigue, poor work performance and decreased immunity. Iron deficiency is the most common form of malnutrition in the world. Iron-deficiency anaemia (inadequate number of red blood cells caused by lack of iron) is highly prevalent in less developed countries, but also remains a problem in developed countries where other forms of malnutrition have already been virtually eliminated. While iron deficiency is not the only cause of anaemia, where anaemia is prevalent, iron deficiency is usually the most common cause.

Pulmonary hypertension refers to a group of diseases that is characterised by high pressure in the pulmonary artery, and pulmonary vascular resistance. Persistent pulmonary hypertension in the newborn is a condition in which the pulmonary artery pressure does not decrease after birth. It may occur in as many as 6.8 in 1 000 live births. Phosphodiesterase type 5 (PDE5) is the predominant phosphodiesterase isoform that metabolises cyclic guanosine monophosphate (cGMP) in the lung. It is upregulated in conditions that are associated with pulmonary hypertension. Thus, by selectively inhibiting PDE5, the accumulation of intracellular cGMP is promoted by sildenafil citrate. The nitric oxide-mediated vasodilatation is also enhanced. It is recommended that more large-scale randomised, controlled clinical trials should be carried out to confirm the efficacy, safety and optimal dosage of sildenafil in the treatment of pulmonary hypertension in neonates and paediatric patients.
Basic nutrition and additional requirements for children who are diagnosed with attention-deficit hyperactivity disorder : paediatricsSource: Professional Nursing Today 16, pp 16 –18 (2012)More Less
Recent research highlights several areas of nutritional concern for children who are 2-8 years of age. These include high intakes of fat and sugar, low intake of fruits and vegetables, limited exposure to a variety of foods, increased fast food consumption and decreased physical activity. These factors contribute to an increased prevalence of overweight and the risk of diabetes and other chronic diseases. Furthermore, the link between artificial food colourings and attention-deficit hyperactivity disorder symptoms has been confirmed.
