ABSTRACT

The lack of effective treatments for dementia has led to explore the potential of antidiabetic agents as a possible approach. This cross-sectional and population-based study aimed to investigate the relationship between each antidiabetic drug and their defined daily doses (DDDs) and the use of anti-Alzheimer's disease (AD) drugs in order to establish new possible hypotheses about the role of antidiabetic drugs in AD. For that purpose, a database containing information on medications prescribed to 233183 patients aged 50 years or older between 2018 and 2020 was used. DDDs were calculated according to the ATC/DDD index 2023. Statistical analyses, with logistic regression, were carried out to assess antidiabetic and anti-AD drugs consumption. A total of 91836 patients who were prescribed at least one antihypertensive, antidiabetic, or lipid-modifying agent were included in the study; specifically, 29260 patients were prescribed antidiabetic medication. Among the antidiabetic agents, glucagon-like peptide-1 analogs (GLP-1) DDDs were likely to have a positive association with anti-AD drugs in people aged between 70 and 80 years. Additionally, sodium-glucose cotransporter 2 inhibitors (SGLT2i) were prone to have a positive association with anti-AD drug usage across almost every age. However, insulin usage was associated with an increased usage of anti-AD agents. In conclusion, there is evidence suggesting a correlation between certain antidiabetic agents and dementia. Specifically, GLP-1 and SGLT2i might be associated with lower odds of anti-AD drugs usage, while insulins might be linked to higher odds of using anti-AD drugs.

ABSTRACT

The purpose of this paper is to verify whether the concentrations of caffeine in saliva are comparable to serum concentrations in preterm infants who are treated with caffeine for apnea of prematurity. This is a prospective observational study. Eligible participants were newborn infants < 37 weeks of gestational age treated with oral or intravenous caffeine for apnea of prematurity. Two paired samples of saliva and blood were collected per patient. Tube solid-phase microextraction coupled online to capillary liquid chromatography with diode array detection was used for analysis. A total of 47 infants with a median gestational age of 28 [26-30] weeks and a mean of 1.11 ± 0.4 kg of birth weight. Median postmenstrual age, when samples were collected, was 31 [29-33] weeks. Serum caffeine median levels of 19.30 µg/mL [1.9-53.90] and salivary caffeine median levels of 16.36 µg/mL [2.20-56.90] were obtained. There was a strong positive Pearson's correlation between the two variables r = 0.83 (p < 0.001). CONCLUSION: The measurement of salivary caffeine concentrations after intravenous or oral administration offers an alternative to serum caffeine monitoring in apnea of prematurity. Measurement of salivary concentration minimizes blood draws, improves blood conservation, and subsequently minimizes painful procedures in premature infants. WHAT IS KNOWN: • Salivary sampling may be useful when is applied to extremely low birth weight infant, in whom blood sampling must be severely restricted. WHAT IS NEW: • The measurement of caffeine salivary concentrations after intravenous or oral administration offers an alternative to serum caffeine monitoring in apnoea of prematurity. • Salivary sampling may be a valid non-invasive alternative that could be used to individualize and optimize caffeine dose.
