    Análisis de la prescripción de medicamentos en una comunidad geriátrica Argentina
    (Sociedad Médica de Santiago, 2013-02) Marzi, Marta Mónica; Diruscio, Valeriana Alejandra; Núñez, Mariano H.; Pires, Miryam Susana; Quaglia, Nora Beatríz
    Background: Although polypharmacy may bejustified in elderly patients with multiple diseases, it may be dangerous, especially when it includes potentially inappropriate medications (PIM). Aim: To identify inappropriate medication and factors associated with the most relevant prescriptions among older people. Material and Methods: Cross-sectional observational analysis of drugs prescribed during the first trimester of 2010 to 179 older adults aged 77 ± 8 years (98 women), living in a geriatric reference hospital in Argentina. The use of potentially inappropriate medications (PIM) in elderly patients was analyzed using Beers Criteria updated to 2012. Results: The mean number of drugs prescribed per individual was 6.1 ± 2.7. The most commonly used drugs were anti-ulcer agents (58.1%), agents acting on the renin-angiotensin system (54.2%), antithrombotic medications (50.8%) and benzodiazepines (50.8 %). The use of antacids and anti-ulcer agents, psychotropic drugs and PIM was significantly higher among patients using six or more drugs daily, compared to the less medicated group (odds ratio (OR) = 6.8, 95% confidence intervals (CI) 3.5-13.2; OR=15.0, 95%CI 5.9-38.4; OR=5.0; 95%IC 2.6-9.8, respectively). Thirty one percent of participants using non-steroidal anti-inflammatory drugs, were not receiving medications for gastric protection. One to four drugs included in the Beers list were prescribed to 66% of participants. Conclusions: Despite the high prevalence of use of antacids and anti-ulcer agents, these drugs were not prescribed to a significant proportion of patients using non-steroidal anti-inflammatory drugs. Strategies to optimize pharmacotherapy in the elderly population are urgently required.

    Seedling emergence and herbage yield of summer-active tall fescue sown at different times and sowing depths
    (Wiley, 2025-03-06) Beribe, María José; Barletta, Pablo; Scheneiter, Jorge Omar; https://orcid.org/0000-0002-3445-1219
    Background: Tall fescue is sensitive to sowing depth and, in the Pampas region of Argentina, its sowing is often delayed from autumn (average air temperature 18.5°C) to winter (average air temperature 10.0°C). Since tall fescue is sensitive to the sowing depth, and temperature determines the emergence period, this study aimed to evaluate the effect of sowing depth at different times on seedling emergence and herbage yield. Methods: Two field experiments were carried out in Pergamino, Buenos Aires province, Argentina, to evaluate a summer-active tall fescue at two sowing times and five sowing depths. The emergence of seedlings and the herbage yield in the year of sowing were determined. Results: Seedling emergence was maximal when sown at 1.2–1.5 cm depth and at 230 growing degree days (GDD) in early autumn and 257 GDD in winter. In both years and sowing seasons, herbage yield was positively related to the number of seedlings at maximum emergence. Conclusions: No differences in seedling emergence were observed between the autumn and winter sowings, and the emergence of tall fescue was well explained by the thermal time. The concept of “critical depth” was determined as the sowing depth at which the greatest seedling emergence and forage yield are achieved.
