RESUMO
Background and objectives: Dengue is one of the most common epidemic infections around the world. Dengue infections in older adults are related to an atypical presentation and a high mortality. Frailty is associated with poor recovery from hospitalization due to infection. However, few studies describe frailty and functional decline after dengue infection. The current case series study aims to investigate the baseline frailty status, functional decline, and time to recovery in older adults after dengue infection. Method: We studied seven patients with post-dengue frailty who had been admitted to the geriatric ward in one tertiary medical center in Taiwan during the 2023 dengue fever outbreak. Result: The mean age was 82 years old. The clinical frailty scale worsened from a mean of 4.7 at baseline to 6.3 at dengue diagnosis. The mean Katz Index of independence in activities of daily living decreased from 10.6 at baseline to 4.7 with dengue, and it recovered to 6.7 one month after discharge. Conclusions: Our preliminary data suggest that there is indeed an increase in frailty in older adults due to dengue. Post-dengue frailty and functional decline might be profound and persistent. Acute geriatric care intervention rehabilitation for frailty after dengue may benefit this population.

To understand the global changes in non-susceptibility rates of Streptococcus pneumoniae to ceftriaxone, we conducted a study using the Antimicrobial Testing Leadership and Surveillance database. A total of 15,717 S. pneumoniae isolates were collected from 2016 to 2021. The minimum inhibitory concentrations (MICs) were determined using broth microdilution. The overall susceptibility rates of S. pneumoniae isolates to penicillin, ceftriaxone and ceftaroline were 63.4%, 94.0% and 99.6%, respectively. The geometric mean of MICs and MIC50/MIC90 values of ceftriaxone were higher in Asia than in other continents. China (33.9%), South Korea (33.8%) and Taiwan (27.6%) had the highest ceftriaxone non-susceptibility rates, followed by Turkey, India, Brazil, Malaysia, South Africa and Colombia, with rates between 10% and 20%. During the study period from 2020 to 2021, Asia had the highest MIC90 value (4 mg/L) for ceftriaxone in S. pneumoniae isolates, and the geometric mean of MICs increased from 0.25 mg/L in 2016-2017 to 0.39 mg/L in 2020-2021. Both Asia (from 83.4% to 75.1%) and Latin America (from 94.2% to 86.3%) showed a decreasing trend in ceftriaxone susceptibility rates from 2016 to 2021. In North America, Europe and Oceania, the susceptibility rate was higher than 95%, and there was no obvious change in the rate during the 6 y. Further analysis of the data from Asia revealed that individuals younger than 6 y of age had a lower susceptibility rate to ceftriaxone (71.6% vs. 81.7%, P < 0.05) than patients ≥6 y. The higher non-susceptibility rates of ceftriaxone in S. pneumoniae in Asia may lead to therapeutic challenges in community-acquired pneumonia.

OBJECTIVES: Trends in the susceptibility to ceftazidime-avibactam (CZA) and tigecycline (TGC) among Enterobacter species from different geographic areas are unknown.This study aimed to analyse the trends in CZA and TGC susceptibility changes across different continents from 2014 to 2021 utilizing Antimicrobial Testing Leadership and Surveillance (ATLAS) data. METHODS: A total of 23 669 isolates of Enterobacter species were collected over an 8-y period. RESULTS: The overall non-susceptibility rate of Enterobacter isolates to both CZA and TGC was 3.2%. India (16.5%), Guatemala (15.4%), and the Philippines (13.1%) exhibited the highest resistance to CZA. The increase in CZA resistance rates was particularly evident in Asia, with an increase from 4.0% to 8.3%, and in Latin America, from 1.5% to 5%. The non-susceptibility rate for TGC mildly increased in Africa/Middle East but decreased in other continents during the study period. The overall rate of carbapenem resistance increased from 2.9% in 2014-2017 to 4.3% in 2018-2021. Among carbapenem-resistant Enterobacter isolates, the CZA resistance rate was highest in Asia (87.4%), followed by Europe (69.2%) and Africa/Middle East (60.8%). Among the 380 Enterobacter isolates resistant to CZA and carbapenem, the most common genotype of carbapenemase genes was blaNDM (59.2%), followed by blaVIM (24.2%), blaOXA (4.2%), blaIMP (1.1%), and blaKPC (1.1%). The susceptibility of carbapenem-resistant Enterobacter to TGC remained high, with an overall susceptibility rate of 90%. CONCLUSIONS: The heterogeneous distribution of CZA resistance rates among different geographical regions highlights the divergent therapeutic options for drug-resistant Enterobacter species.

OBJECTIVE: To understand the global changes in the nonsusceptibility rates of Escherichia coli to meropenem and ceftazidime-avibactam (CZA), we conducted a study using the Antimicrobial Testing Leadership and Surveillance database. METHODS: A total of 49 394 E. coli isolates were collected during the 8-year study period. RESULT: The countries with the highest nonsusceptible rates for meropenem were India (16.6%), followed by Pakistan (6.7%), Ukraine (5.4%), Qatar (5.3%), and Guatemala (3.2%). For CZA, the nonsusceptible rate was highest in India (15.6%), followed by Qatar (4.0%), Guatemala (3.9%), China (2.6%), and Thailand (2.5%). During the study period, the nonsusceptible rates of meropenem and CZA in E. coli increased in Asia, Latin America, and Africa/Middle East. Isolates from the medical ICU (odds ratio [OR], 4.62) and surgical ICU (OR, 3.98) were associated with a higher risk of CZA nonsusceptible rates. Compared to intestinal specimens, respiratory and genitourinary specimens had the highest OR (2.32 and 2.17) associated with CZA resistance. Further analysis of carbapenemase distribution showed an increase in the percentage of blaNDM-positive isolates and a decrease in blaKPC-positive isolates worldwide, especially in Latin America. Additionally, we observed a gradual decline in the prevalence of blaOXA-positive E. coli without concomitant carriage of metallo-ß-lactamase genes in the worldwide surveillance. CONCLUSIONS: Further surveillance is necessary to determine whether blaNDM -positive E. coli (i.e., CZA-resistant isolates) is increasing and leading to more superbugs spreading worldwide.

OBJECTIVE: This study aimed to clarify the relationship between oral frailty and oral dysbiosis among hospitalized patients aged ≥ 50 years. METHODS: A prospective observational study was conducted. Number of teeth, masticatory ability, articulatory oral motor skill, tongue pressure, swallowing pressure, and choking were used to assess oral frailty. Saliva samples were collected from the oral cavity for bacterial culture. RESULTS: A total 103 in patients enrolled and 53.4% suffered from oral frailty. Oral frailty was found to have a 3.07-fold correlation with the presence of Enterobacterales in the oral cavity (p = 0.037), especially in poor articulatory oral motor skill, which showed at greater risk of Enterobacterales isolated from the oral cavity by 5.58-fold (p = 0.01). CONCLUSION: Half of hospitalized patients was found to have oral frailty that was related to more Enterobacterales in the oral cavity. This evidence suggests that the enhancement of articulatory oral motor skills may serve as a potential strategy for mitigating the presence of Enterobacterales within the oral cavity.

AIM: To evaluate oral frailty features present in hospitalized older patients with aspiration pneumonia. METHODS: We enrolled hospitalized patients aged ≥50 years and classified them into three groups: the community-acquired, aspiration, and non-community-acquired pneumonia groups. Oral frailty was defined as meeting three or more criteria from the following: choking, and decreased occlusal force, masticatory function, tongue-lip motor function, tongue pressure, and tongue pressure during swallowing. RESULTS: Of 168 patients enrolled, the incidence of aspiration pneumonia was 23.9% (17/71) in patients admitted with pneumonia as the primary diagnosis. The occlusal force and masticatory function were significantly poorer and tongue pressure and tongue pressure during swallowing were significantly lower in the aspiration pneumonia group than in the other two groups. A higher number of chronic comorbidities, poor oral health, and lower tongue pressure during swallowing were significantly associated with aspiration pneumonia. A tongue pressure during swallowing of <10.32 kPa might be a cutoff point for predicting the risk of aspiration pneumonia. CONCLUSIONS: Hospitalized patients aged ≥50 years with multiple comorbidities, poor oral hygiene, and oral frailty during swallowing are at a higher risk of developing aspiration pneumonia, especially when their tongue pressure during swallowing is <10.32 kPa. Aspiration pneumonia is a preventable disease. Healthcare professionals should incorporate tongue pressure measurements or other screening tools into routine clinical practice to facilitate the early detection of this condition and intervention.

INTRODUCTION AND OBJECTIVES: Functional decline frequently occurs in older adults in hospitals. The aim of this project was to promote evidence-based strategies for physical activity to prevent functional decline in hospitalized older adults in a medical center in southern Taiwan. METHODS: This project was guided by the JBI Evidence Implementation Framework. Seven audit criteria were derived from a JBI evidence summary and a baseline audit involving 25 nurses and 30 hospitalized older adults was conducted to compare current practice with best practice recommendations. The JBI Getting Research into Practice (GRiP) approach was used to identify barriers to implementation, and strategies were developed to overcome those barriers. A follow-up audit was conducted to measure any changes in compliance. RESULTS: After implementing the strategies, the pass rate of nursing staff improved in the physical activity knowledge test, rising from 56% to 88%. Compliance of nursing staff with providing physical activity instructions using evidence-based guidelines to hospitalized older adults reached 80%. The incidence of functional decline among hospitalized older adults decreased from 36.7% to 20%. CONCLUSIONS: The results of this best practice implementation project suggest that initiating physical activity as early as possible for hospitalized older adults once their medical condition has stabilized can help prevent functional decline.
