ABSTRACT

BACKGROUND: Although swallowing exercises are a fundamental treatment for dysphagia, few studies have evaluated the effectiveness of swallowing training in patients with Alzheimer's disease. METHODS: We recruited 93 patients with Alzheimer's disease from three hospitals in Guangdong, China. This was a parallel armed randomized controlled trial that randomly assigned patients to intervention (n = 48) and control (n = 45) groups. The intervention group adopted systematic stepwise swallowing training for four weeks based on routine dysphagia care. The control group implemented routine dysphagia care, including diet and posture management and health education about swallowing dysfunction. The swallowing function was the primary outcome, which was assessed using the Water Swallowing Test and Standard Swallowing Assessment. An abnormal eating behavior questionnaire was used to assess the incidence of aberrant eating behavior in patients with Alzheimer's disease. The Mini-Nutritional Assessment Short Form and Barthel index were adopted to evaluate the nutritional status and ability to carry out daily activities between groups. SPSS software was used to perform the chi-square test, t-test, and generalized estimation equation for data analysis. RESULTS: We analyzed the effects of the stepwise swallowing training program using the generalized estimating equation method. The intervention group exhibited greater improvements in their swallowing function (Water Swallowing Test: ß = -3.133, 95 % CI: -4.113, -2.154, P < 0.001; Standard Swallowing Assessment: ß = -5.813, 95 % CI: -7.782, -3.844, P < 0.001), abnormal eating behaviors (abnormal eating behavior questionnaire: ß = -13.324, 95 % CI: -21.643, -5.005, P = 0.002), daily function (Barthel index: ß = 11.280, 95 % CI: 4.021, 18.540, P = 0.002), and nutritional status (Mini-Nutritional Assessment Short Form: ß = 2.402, 95 % CI: 1.313, 3.490, P < 0.001) over time than the routine-care group in the fourth week. CONCLUSIONS: Stepwise swallowing training is a safe and effective intervention for managing dysphagia and other related symptoms in patients with Alzheimer's disease.

ABSTRACT

The occurrence and characterization of carbapenemase-producing Enterobacteriaceae from companion animals in Guangzhou, China, are investigated. Six isolates (2.3%, 6/257) were positive for blaNDM-5, that is, one Enterobacter cloacae, one Citrobacter freundii, and four Escherichia coli. Three E. coli isolates obtained from the same animal hospital were ST410 and showed identical pulse field gel electrophoresis pattern, resistance profiles, and resistance genes. blaNDM-5 was located on IncX3 (n = 5) and IncK2 (n = 1) plasmid, respectively. The presence of carbapenemase-producing Enterobacteriaceae among companion animals needs continued surveillance.

ABSTRACT

The purpose of this study was to investigate the occurrence of plasmid-mediated colistin resistance gene mcr-1 in Enterobacteriaceae isolates from companion animals in Guangzhou, China. Enterobacteriaceae isolated from 180 samples collected from cats and dogs were screened for mcr-1 by PCR and sequencing. MCR-1-producing isolates were further characterized by multilocus sequence typing and pulsed-field gel electrophoresis (PFGE). Plasmid characterization was performed by conjugation, replicon typing, S1-PFGE, and Southern blot hybridization. Plasmid pHN6DS2 as a representative IncN1-IncHI2/ST3 plasmid from ST93 E. coli was fully sequenced. pHN6DS2-like plasmids were screened by PCR-mapping and sequencing. The mcr-1 gene was detected in 6.25% (8/128) Escherichia coli isolates, of which, five belonged to E. coli ST93 and had identical PFGE patterns, resistance profiles and resistance genes. mcr-1 genes were located on ∼244.4 kb plasmids (n = 6), ∼70 kb plasmids, and ∼60 kb plasmids, respectively. Among them, five mcr-1-carrying plasmids were successfully transferred to recipient by conjugation experiments, and were classified as IncN1-IncHI2/ST3 (∼244.4 kb, n = 4, all obtained from E. coli ST93), and IncI2 (∼70 kb, n = 1), respectively. Plasmid pHN6DS2 contained a typical IncHI2-type backbone, with IncN1 segment (ΔrepA-Iterons I-gshB-ΔIS1294) inserted into the multiresistance region, and was similar to other mcr-1-carrying IncHI2/ST3 plasmids from Enterobacteriaceae isolates of various origins in China. The remaining five mcr-1-bearing plasmids with sizes of ∼244.4 kb were identified to be pHN6DS2-like plasmids. In conclusion, clonal spread of ST93 E. coli isolates was occurred in companion animals in Guangzhou, China.
