[Prevalence of malnutrition and influence of oral nutritional supplementation on nutritional status in institutionalized elderly]. / Prevalencia de desnutrición e influencia de la suplementación nutricional oral sobre el estado nutricional en ancianos institucionalizados.

BACKGROUND: Nutritional supplementation might be an effective strategy for improving the nutritional status and the quality of life of institutionalized fragile elderly. OBJECTIVES: The prevalence of malnutrition and its relation with disease, and the influence of dietary supplementation by means of oral formulas on the nutritional status of elderly nursing home residents were assessed. METHODS: Two studies were carried out, one a cross-sectional survey in 31 subjects and the other a longitudinal-sectional survey in 19 subjects, both groups living in a public nursing home in the city of Murcia (SE Spain). Body mass index (BMI), serum albumin concentration (ALB) and geriatric nutritional risk index (GNRI) were assessed as markers of potential malnutrition. Illnesses were ascertained from medical records. RESULTS AND DISCUSSION: The prevalence of malnutrition of the total collective was high (39%), and especially in the fragile subjects (50%). The administration of oral nutritional supplements in the usual diet for 12 months significantly increased ALB and GNRI, and had no effect on body weigh and BMI. Jointly, these effects decreased the in the number of subjects at high nutritional risk and increased the number of subjects with a low or zero risk of malnutrition. CONCLUSION: The administration of oral nutritional supplements in the usual diet of this elderly collective is an effective clinical strategy in nutritional therapy.

[Epidemiology and burden of acute otitis media in Valencia (Spain)]. / Epidemiología e impacto de la otitis media aguda en la Comunidad Valenciana.

OBJECTIVE: To assess the burden (incidence, treatment and complications) of acute otitis media (AOM) and otitis media with effusion (OME) in children younger than 5 years of age from Valencia, Spain. SUBJECT AND METHODS: We performed a retrospective cohort study of 1,399 children followed-up for the first 5 years of life. Seventeen pediatricians reviewed the medical records of their patients born in 1995 and 1996 and followed-up from birth until the age of 5 years. For each child, the number of otitis episodes, treatment, complications, and surgical interventions was obtained. RESULTS: There were 2,961 episodes of AOM in the first 5 years of life (2.23 cases/child). Four hundred seventy-six cases (16.1 %) occurred before 1 year of age and 1,346 between the first and second year of life (45.5 %). By the third year of life, 59.8 % had had at least one episode. In most children (80.9 %), diagnosis was made in primary care and required a median of 1.81 visits/episode for follow-up. A total of 94.5 % were treated with antibiotics (amoxicillin-clavulanate 38.8 %, cefuroxime 14.3 %, clarithromycin 8.2 % and amoxicillin 5.9 %) and 8.5 % required a change of antibiotic therapy. Two hundred seventeen children (15.2 %) had at least one episode of OME. Twenty-six patients (1.8 %, 95 % CI: 1.2-2.7 %) required insertion of ventilation tubes. Twenty-four patients (1.7 %) had secondary hypoacusis. There was one case of meningitis and two cases of chronic otorrhea. No cases of mastoiditis were recorded. CONCLUSIONS: The incidence of AOM in Valencia is 40,014 episodes/100,000 children younger than 5 years/year (95 % CI: 39,700-40,300). It represents a significant burden due to the large number of visits, antibiotic use, associated surgical procedures and need for auditory rehabilitation.
