RESUMEN
Objective:To investigate the effect of multiple medications on the risk of small intestinal bacterial overgrowth(SIBO)in the elderly.Methods:Clinical data of 85 inpatients in the Department of Geriatrics, the First Hospital of Lanzhou University undergone HMBT from August 2017 to April 2021 were retrospectively analyzed.According to the HMBT results, they were divided into a SIBO(+ )group and a SIBO(-)group.Polypharmacy was defined as ≥ 5 types of medications.We analyzed the difference in the rate of polypharmacy between the two groups.Results:A total of 85 hospitalized elderly patients were included in the study.Of these patients, 38(44.71%)tested positive for SIBO.Polypharmacy occurred in 41 patients(48.24%). There were significant differences in types of drugs and polypharmacy between the SIBO(+ )group and the SIBO(-)group( t=3.01 and χ2=14.33, P<0.05 for both). Moreover, polypharmacy was a risk factor for SIBO( P=0.017, OR=10.85, 95% CI: 1.52-77.29). Among 14 commonly used drugs, gastrointestinal motility drugs were closely related to SIBO.There was a positive correlation between polypharmacy and the change in hydrogen levels at 90 min( P=0.040, r=0.22, 95% CI: 0.01-0.42). Conclusions:Polypharmacy is correlated with SIBO in the elderly, is a risk factor for SIBO and is helpful in clinical practice to assess the risk of SIBO and decide further examinations, contributing to early diagnosis and early treatment.
RESUMEN
Objective: To investigate the inlfuence of different blood pressure (BP) circadian rhythm on cardiac function in hypertensive patients. Methods: A total of 180 hypertensive patients with well controlled day-time blood pressure were divided into 3 groups. Dipper group, n=30, Non-dipper group, n=99 and Reverse dipper group, n=51. The relationship between cardiac function, relevant clinical index and blood pressure circadian rhythm were analyzed. Results: The mean systolic and diastolic BP, BP classiifcation and the antihypertensive medication were similar among 3 groups.①The ratio of peak mitral E wave to peak mitral annulus E' wave (E/E') increased accordingly from Dipper group, Non-dipper group and Reverse-dipper group as (8.1 ± 2.4), (8.6 ± 2.5) and (9.6 ± 3.2), P Conclusion: Abnormal blood pressure circadian rhythm was associated with the cardiac injury in hypertensive patients. The cardiac injury increased accordingly from Non-dipper group to Reverse-dipper group and the main damage was in diastolic function.
