Abstract The work reported in this paper addresses the iodine nutritional deficiency that still affects a large number of people. For this purpose, we analyzed the possibility to use, as iodine vehicle, a hard typical ewe cheese, called Canestrato d'Abruzzo, derived from milk of ewes fed with an iodine-fortified diet. Both in the milk and the cheese of these animals, the iodine level was higher than that measured in sheep with a normal diet. An increase in the lactoferrin and iron content was evident in the whey derived from milk of the iodine group. Furthermore, in derived cheese, the caseins seemed more efficiently transformed in small peptides making the product more digestible and, for this reason, particularly suitable for feeding the elderly. In conclusion, the dairy products obtained from ewes fed with iodine diet contain more bioactive compounds so that they represent a useful food to prevent iodine and iron deficiency in lamb and humans.

Aged Subjects

Iron deficiency (ID) is the most frequent nutritional deficiency in the whole population worldwide, and the second most common cause of anemia in the elderly. The prevalence of anemia is expecting to rise shortly, because of an ageing population. Even though WHO criteria define anemia as a hemoglobin serum concentration <12 g/dL in women and <13 g/dL in men, several authors propose different and specific cut-off values for the elderly. Anemia in aged subjects impacts health and quality of life, and it is associated with several negative outcomes, such as longer time of hospitalization and a higher risk of disability. Furthermore, it is an independent risk factor of increased morbidity and mortality. Even though iron deficiency anemia is a common disorder in older adults, it should be not considered as a normal ageing consequence, but a sign of underlying dysfunction. Relating to the molecular mechanism in Iron Deficiency Anemia (IDA), hepcidin has a key role in iron homeostasis. It downregulates the iron exporter ferroportin, inhibiting both iron absorption and release. IDA is frequently dependent on blood loss, especially caused by gastrointestinal lesions. Thus, a diagnostic algorithm for IDA should include invasive investigation such as endoscopic procedures. The treatment choice is influenced by the severity of anemia, underlying conditions, comorbidities, and the clinical state of the patient. Correction of anemia and iron supplementation should be associated with the treatment of the causal disease.

Prevalence Of Anemia

Objective. To describe de prevalence of iron deficiency (ID) and anemia in a sample of Mexican elderly population from the National Health and Nutrition Survey (Ensanut) 2012. Materials and methods. 1 920 subjects ≥60 years of age were included. Hemoglobin, serum concentrations of ferritin and CRP were measured. The risk for ID and anemia adjusted for potential confounders was assessed in logistic regression models. Results. The overall prevalence of anemia was 13.9%, 15.2% in males and 12.8% females. For ID,overall it was 4.2%, males 4.0% and females 4.3%. The greatest prevalence of ID was found in males and females over 80 years old (6.9 and 7.0%, respectively). ID was present in 1.5 of 10 Mexican elders with anemia. Conclusion. The prevalence of anemia was high in the elderly, however the prevalence of ID was low; there is a need to further investigate the causes of anemia in this age group.

<p class="abstract"><strong>Background:</strong> The elderly have limited regenerative abilities thus predisposing them to various diseases. Measuring both serum ferritin and transferrin serve as biomarkers of iron deficiency. This study, using enzyme-linked immunosorbent assay (ELISA) determined the serum levels of ferritin and transferrin in the elderly. Full blood count was also done and correlated with serum ferritin and transferrin levels of every participant.</p><p class="abstract"><strong>Methods:</strong> This was a cross-sectional study at the Geriatric Clinic of Lagos State University Teaching Hospital (LASUTH). Following receipt of written consents from ninety (90) elderly participants, venous samples were drawn for full blood count (FBC) and samples for serum ferritin and transferrin ELISA assay collected and stored at -40<sup>o</sup>C until the required sample size was obtained. Data were analyzed using SPSS version 23.0 (Statistical Package for Social Sciences, Inc., Chicago, Ill). The Pearson chi-square test was used for statistical analysis. P value was considered to be statistically significant when &lt;0.05.  </p><p class="abstract"><strong>Results:</strong> Participants consisted of 50 (55.6%) females and 40 (44.4%) males. The mean age of all participants was 71.31±7.38 years. The Majority, 90% (36 of 40) of the males had haemoglobin values lower than 13 gm/dl, while 66% (33 of 50) of females had haemoglobin values lower than 12 gm/dl. The mean ferritin concentration of all participants was 196.19 ±121.21ng/ml. The overall mean serum transferrin was 0.187±0.157 ng/ml with a minimum of 0.03 ng/ml and a maximum of 1.18 ng/ml.</p><p class="abstract"><strong>Conclusions:</strong> Anaemia in the elderly is very common using the World Health Organization (WHO) haemoglobin cut-off values, however, iron deficiency anaemia prevalence is low.</p>
