La implantación de una prótesis total de cadera (PTC) es un procedimiento habitual en cirugía ortopédica, que frecuentemente precisa reposición hemática en el postoperatorio inmediato. El porcentaje de pacientes protetizados que recibe una transfusión homóloga oscila en torno al 60% (1). Sin embargo, esta práctica no está exenta de riesgos; se asocia a un riesgo de transmisión de enfermedades infeccionas, riesgo de aloinmunización, reacciones hemolíticas o febriles por aloanticuerpos, reacciones injerto contra huésped y se le atribuye mayor incidencia de infecciones y una estancia hospitalaria más prolongada (1,2). Además, es un recurso caro y no siempre disponible. Con objeto de minimizar las necesidades de transfusión homóloga en pacientes que iban a ser intervenidos de prótesis total de cadera se diseñó un programa de ahorro de sangre basado en la autodonación prequirúrgica en pacientes que cumplieran los criterios de selección. Entre 1996 y 2001 se incluyeron en este programa 220 pacientes, consiguiéndose

South Africa has the world's fourth highest number of deaths associated with asthma among people ... more South Africa has the world's fourth highest number of deaths associated with asthma among people between 5 and 35 years of age. Asthma is a condition characterized a physiological response that results in the blockade of the pulmonary airways through triggers of bronchoconstriction and mucous secretion. This observational study aimed to investigate the prevalence of asthma among Pearson Institute of Higher Education students on a single campus and to assess the related patterns of use of prescription medicines. Data were collected in the form of an electronic survey through the My Learning Management System (myLMS) platform to better reach the study population. Descriptive statistics, bar charts and histograms were generated with Excel version 2016 in Microsoft Windows. The results showed that clinically diagnosed asthmatic students predominantly used inhalers containing beta subtype two (β2-) adrenergic agonists. Findings indicated a 45% chance of ashtmatic students complying with their treatment regimen and an 18% chance of these students co-using other drug treatments. Researchers concluded that the pattern of usage of asthma medicines by affected students increases the risk for asthma attacks. Tertiary institutions need to ensure they are equipped and prepared to respond to these incidents when they occur. Asthma is a chronic respiratory condition that is characterised by the narrowing of the airway or complete airflow obstruction due to inflammation and mucus secretion. Factors that trigger asthma include exposure to allergens or other environmental irritants [1], and exercise may exacerbate the condition [2]. Smoking and the use of alcohol has shown to affect asthma negatively, in that smoking may cause a decline in lung function and alcohol is associated with a change in the characteristics of airway mucus, smooth muscle regulation of airways diameter, and in bronchial blood flow [3]. The severity of the condition influences the frequency and seriousness of the general symptoms that patients experience during an asthma attack, which include coughing, wheezing, chest tight-(2014): 429-434.
