ABSTRACT

BACKGROUND: The timed up and go (TUG) test assesses balance and mobility performance. AIM: This study aims to investigate the association between TUG time and mortality in Japanese older persons and to clarify possible moderation effects on mortality and TUG time. METHODS: In all, 874 participants who were ≥ 65 years of age completed the TUG test and had their anthropometric parameters and physical functions measured. We investigated the association between all-cause mortality and TUG using a Cox regression model that included confounders, and explored the time associated with mortality using a restricted cubic spline. We also performed subgroup analyses to explore whether age, sex, and body mass index (BMI) affected the relationship between TUG time and mortality. RESULTS: The median age and mean follow-up period were 74 and 8.5 years, respectively. Median TUG time was 7.4 s and the prevalence of mortality was 25.7%. TUG time in one second was positively associated with an increased risk of total mortality [hazard ratio (HR): 1.054 (1.016-1.093); P = 0.005] in the Cox regression model. The positive association of mortality and TUG time was present when the TUG was over 10.5 s in the restricted cubic spline curve. Older age (75 years or older) moderated the relationship between TUG time and mortality [Pinteraction = 0.096]. CONCLUSION: This study demonstrates that TUG time is associated with all-cause mortality in Japanese older adults.

ABSTRACT

BACKGROUND AND AIM: Disability is an important health problem among older individuals, prompting the need for long-term care. Age-related disability is usually associated with mobility; however, little is known about the association between mobility and long-term care. Therefore, this study aimed to clarify the association between the timed up and go (TUG) test measuring mobility and long-term care eligibility. PATIENTS AND METHODS: We analyzed follow-up data of 489 community-dwelling healthy older adults (≥ 65 years) who participated in a prospective observational study. They were divided into certified (59 participants) and uncertified (430 participants) groups based on long-term care eligibility. Anthropometric and physical functioning measures included the TUG test and hand grip strength (HGS), among others. These measures were compared between groups and a multivariate logistic regression analysis evaluated the association between the TUG test times and long-term care eligibility. RESULTS: Participants' minimum follow-up period was 4 years. TUG times were significantly slower (median time: 7.4 vs. 8.3 s, p < 0.001) and HGS and knee-extension strength significantly lower in the certified group than in the uncertified group. The logistic regression analysis showed that TUG times were significantly associated with long-term care eligibility after adjusting for potential covariates. In addition, mediation analysis showed that 53.1% of the association between HGS and long-term care eligibility was mediated through TUG times. CONCLUSION: The TUG test was associated with long-term care eligibility among healthy older adults, implying that the test may be helpful as a predictor for the early determination of dependence in old age.

ABSTRACT

Emphysematous prostatic abscess is a rare clinical entity of uncomplicated urinary tract infections with high mortality rate. Here we report a case of hypermucoviscous Klebsiella pneumoniae causing emphysematous prostatic abscess, emphysematous cystitis, and renal abscess simultaneously in a 75-year-old Japanese male with diabetes mellitus and advanced gastric cancer. The patient was successfully treated with prolonged intravenous antimicrobial agents.

ABSTRACT

OBJECTIVES: Corynebacterium spp. are becoming recognized as pathogens that potentially cause various infections. We aimed to evaluate the clinical characteristics associated with Corynebacterium spp. bacteremia. PATIENTS AND METHODS: We retrospectively reviewed the medical records of all adult patients who had positive blood cultures for Corynebacterium spp. in a single university hospital between January 2014 and December 2016. Patients were divided into a bacteremia group and a contamination group based on microbiological test results and clinical characteristics. Patients' characteristics, antimicrobial susceptibility of isolated species, antimicrobials administered, and patient outcomes were evaluated. RESULTS: Corynebacterium spp. were isolated from blood samples of 63 patients; Corynebacterium striatum was the predominant isolate. Twenty-eight patients were determined to have bacteremia. Younger age (p=0.023), shorter time to positivity (p=0.006), longer hospital stay (p=0.009), and presence of an indwelling vascular catheter (p=0.002) were observed more often in the bacteremia group compared to the contamination group. The source of infection in most patients with bacteremia was an intravenous catheter. All tested strains were susceptible to vancomycin. Four of the 27 patients with bacteremia died, despite administration of appropriate antimicrobial therapy. CONCLUSIONS: We found that younger age, shorter time to positivity, and presence of an indwelling catheter were related to bacteremia caused by Corynebacterium spp. Appropriate antimicrobials should be administered once Corynebacterium spp. are isolated from the blood and bacteremia is suspected.

ABSTRACT

Edwardsiella tarda is commonly isolated from aquatic environments and a variety of animals. We present the first case of E. tarda bacteremia with psoas and epidural abscess. The patient was a 65-year-old woman with recurrent gastric cancer who had frequently consumed raw fish and grilled eel. She was successfully treated with antimicrobials and surgery. We also review reports published in English regarding E. tarda bacteremia in Japan and the experience at our hospital. On the basis of this review, we conclude that the major underlying disease leading to E. tarda bacteremia is malignancy and that the gastrointestinal tract is the most commonly affected organ. The overall mortality rate due to E. tarda bacteremia in our review was 38.1% (8/21). Although E. tarda bacteremia is rare, clinicians should be aware of this fatal food-borne infection.

ABSTRACT

BACKGROUND: Inappropriate antimicrobial therapy often leads to poor outcomes. This study aimed to evaluate the impact of an antimicrobial stewardship program (ASP) team on appropriate therapy, in patients with bacteremic urinary tract infection (UTI). PATIENTS AND METHODS: We retrospectively reviewed the interventions by the ASP team in 807 patients with bacteremic UTI. Interventions were divided into 3 groups: group A (conventional report), group B (conventional report and written alert on the chart), and group C (conventional report and oral recommendation with/without written alert). The appropriateness of antimicrobial therapy was assessed at 2 time points, based on blood culture results. RESULTS: The ASP team estimated that 166 and 576 patients received inappropriate antimicrobial therapy based on the results of Gram staining, and final report, respectively. Appropriate therapy after intervention was administered to 53.2% of group A, 63.5% of group B, and 89.3% of group C patients, respectively. Mortality was significantly lower in patients of de-escalation than in those with no antimicrobial changes, without prolonged hospital stay. CONCLUSION: This study provides one plausible benchmark for appropriate antimicrobial therapy by ASP, while observer bias and survivor treatment selection bias exist, and further studies including evaluation for severity are needed.

ABSTRACT

A 39-year-old pet shop employee who sustained a bite from one of his store's rats developed fever and arthritis. Streptobacillus moniliformis was cultured from the patient's blood, confirming a diagnosis of rat-bite fever. Treatment with standard antibiotics was successful. Although rat-bite fever is commonly considered a zoonosis transmitted by wild or laboratory rats, our case emphasizes that it may be transmitted by pet animals as well.

ABSTRACT

Poor dentition and/or dental infection due to insufficient oral care are presumed to be risk factors for infective endocarditis (IE). We present a case of endocarditis caused by Granulicatella adiacens and Sjögren's syndrome (SS) with oral complications diagnosed simultaneously. A 67-year-old woman was admitted to our hospital with fever, general fatigue, arthralgia, and back pain. She was diagnosed with primary SS according to the criteria of the American-European Consensus Group. Transthoracic echocardiography carried out to examine her persistent fever revealed vegetation formation (14 × 5 mm) on the aortic valve and her blood cultures were positive for G. adiacens. According to modified Duke's criteria, she was also diagnosed with IE. She underwent aortic valve replacement and was administered ampicillin with gentamicin for 6 weeks following surgery. G. adiacens, which is formerly known as one of the nutritionally variant streptococci, is found as part of the normal microbiota of the oral cavity. The patient had chronic periodontitis associated with SS that likely predisposed to G. adiacens bacteremia and subsequent seeding of the aortic valve. Patients with SS may be at risk of IE because of the increased risk of bacteremia from oral complications such as dental caries or periodontal disease. An association between SS and IE has not yet been reported. Our case indicates that SS may be the underlying pathology in patients with IE due to an oral bacterium.

ABSTRACT

Streptococcus agalactiae (S. agalactiae) is a major cause of invasive disease in neonates and pregnant women, but has also recently been observed among non-pregnant adults, especially elderly persons or persons with underlying chronic disease. S. agalactiae is also a rare cause of infective endocarditis, and most cases require early surgery. We report the case of a 43-year-old previously healthy man who experienced rapid progressive culture-negative infective endocarditis with aortic valve vegetation and severe aortic regurgitation, which was complicated by lumbar spondylodiscitis. Emergency aortic valve replacement was performed on the day of his admission, which revealed a congenital bicuspid aortic valve was ruptured by the vegetation. The resected aortic valve specimen was submitted for 16S ribosomal RNA gene sequencing, which revealed that the pathogen was S. agalactiae. Therefore, S. agalactiae should be considered a potentially causative pathogen in cases of rapid progressive infective endocarditis, even if it occurs in a non-pregnant immunocompetent adult.
