El estudio realizado fue de tipo descriptivo retrospectivo, con el propósito de determinar la recurrencia de las hernias inguinales de acuerdo a las técnicas de reparación quirúrgica en los pacientes postoperados en el Servicio de Cirugía General de adultos del Hospital Regional de Zacapa entre enero de 2013 a diciembre de 2017. La información obtenida fue por medio de la ficha recolección datos, que ayudó a determinar una alta prevalencia de recurrencia de hernia inguinal con un 7% (10) de 137 casos que fueron intervenidos por hernia inguinal, con un predominio en el sexo masculino con un 90% (9), la edad dominante fue rango de ˃60 años con 60% (6), según su cronología tiene predominio en un 100% (10) para recurrencia tardía. Según escala de Campanellí la mayor frecuencia fue de R2 con un total de 60% (6) de tipo ind...

Raulin, a student of Louis Pasteur, reported that Zn was required for growth of the fungus Aspergillus niger (Raulin, 1869). A half-century later, Mazé reported that Zea mays (maize) plants required Zn for growth (Mazé, 1914). However, this finding was questioned for inconsistent reproducibility. Fortunately, those results stimulated investigations to obtain more conclusive evidence. In 1926, Zn became generally recognised as essential for higher plants, after Sommer and Lipman showed the effects of Zn deficiency in Hordeum vulgare (barley) and Helianthus annuus (sunflower), which were grown hydroponically (Sommer and Lipman, 1926). In 1934, Zn was established as essential for higher animals by Todd, Elvehjem and Hart (Todd et al., 1980). In 1961, it was documented that Zn was essential for humans, after Prasad studied cases of Zn deficiency in Iran and Egypt (Prasad et al., 1963). Zinc deficiency An adult human body contains an average of 2.5 grams of Zn, and a person should consume 8 to 15 mg of Zn per day in the diet (Royal Society of Chemistry; U.S. Department of Health & Human Services). Zinc deficiency affects two billion people in the world (Prasad, 2003; Müller and Krawinkel, 2005). Around 2800 human proteins contain zinc-binding domains, corresponding to 10% of the human proteome, 40% of them are transcription factors and the Chapter 1 9 rest are mainly enzymes (Andreini et al., 2006). Zinc is involved in a multitude of biochemical processes associated with immunity, wound healing, growth, communication among cells, such as cells in the salivary gland or neurons (Roohani et al., 2013). Zn deficiency causes a broad range of symptoms, depending upon the severity of the condition. Mild Zn deficiency is the most important numerically (Roohani et al., 2013), and its symptoms are growth retardation, impaired immunity, cognitive impairment, neurological disorders, and delayed wound healing (Prasad, 2012). Zinc deficiency increases young children's risks to suffer diarrhoeal disease, pneumonia, and malaria (Caulfield and Black, 2004; Black et al., 2008), which accounts for 29% of all deaths of children under five years old (World Health Organisation; Global Health Observatory data). One of the strategies to improve Zn status in vulnerable human populations is through biofortification of crops. This strategy aims to increase the nutrients content of staple food through agronomical practices and genetic improvement (Roohani et al., 2013). In low-and middleincome regions the population diet relies on staple food, such as cereals, if these crops are grown on Zn deficient soils, their edible parts will be Zn deficient, as well. Thus, in low-and middleincome regions, Zn deficiency in humans is strongly correlated with Zn deficiency in soils.
