Carbapenemase-producing Enterobacteriaceae (CPE) are a serious public health concern and represent a major threat to immunocompromised hosts, including solid organ (SOT) and stem cell transplant (HSCT) recipients. Transplant patients are at particular risk of developing CPE colonization and/or infection due to their frequent exposure to prolonged courses of broad-spectrum antibiotics, altered immunocompetence and exposure to invasive procedures and immunosuppressive drugs. Gut colonization with CPE, in particular carbapenem-resistant Klebsiella pneumoniae, may occur before or after SOT in 2%-27% of patients and among 2%-9% of HSCT and has been associated with increased risk of developing CPE infections. In endemic areas, CPE infections occur in up to 18% of SOT, and HSCT patients can account for 5%-18% of all patients with CPE bacteraemia. Mortality rates up to 70% have been associated with CPE infections in both patient populations. The rapid initiation of an active therapy against CPE is advocated in these infections. Therapeutic options, however, are limited by the paucity of novel compounds that are currently available and by potential antibiotic-associated toxicities. EGFR phosphorylation Therefore, a multidisciplinary approach involving infection control and antimicrobial stewardship programmes still represents the mainstay for the management of CPE infections among transplant patients. The evidence for the use of prevention strategies such as CPE-targeted perioperative prophylaxis or gut decolonization is still scarce. Large, multicentre trials are required to better define prevention strategies and to guide the management of CPE infections in the transplant setting.
The worldwide spread of carbapenemase-producing Gram-negative bacteria (GNB) in healthcare settings is worrying. Of particular concern is the occurrence of Klebsiella pneumoniae carbapenemase (KPC)-producing Klebsiella pneumoniae (KP). In recent years, several guidelines and recommendations have focused on the control of carbapenem-resistant GNB. It remains, however, unknown to what extent individual infection control measures are effective. link2 Our aim was to critically review the recent evidence regarding the effectiveness of measures to control KPC-KP spread in healthcare settings.

Critical review of the literature aiming to evaluate, in accordance with published recommendations, all available studies reporting infection control (IC) measures to control KPC-KP published in the past 5 years.

Among 11 included studies, the majority consisted of outbreak reports, where application of measures was reported in the absence of control groups. link3 Variability was observed related to the frequency of application of rjor healthcare problem worldwide.Antimicrobial stewardship programmes are widely considered to be a core component of the response to the antimicrobial resistance threat. However, a positive impact of these interventions in terms of microbiological outcomes remains difficult to demonstrate, especially when focusing on specific resistant phenotypes. EGFR phosphorylation The first part of this review aims to explore the complex relationship between antibiotic exposure and resistance development in KPC-producing Klebsiella pneumoniae. In the second part we aim to summarize published examples of antimicrobial stewardship interventions intended to impact on the epidemiology of KPC-producing K. pneumoniae. For this purpose, a literature search was performed and seven studies were included in the review. Both restrictive and non-restrictive interventions were associated with an overall reduction in antibiotic consumption, and a decrease in carbapenem resistance rates was observed in five studies. The overall quality of the evidence was low, mainly due to the poor reporting of microbiological outcomes, lack of a control group and suboptimal study design. Although the link between antibiotic use and resistance development is supported by strong evidence, demonstrating the impact of antimicrobial stewardship interventions on microbiological outcomes remains difficult. Studies with adequate design and appropriate outcome measures are needed to further promote antimicrobial stewardship and elucidate which interventions are more successful for controlling the spread of KPC-producing K. pneumoniae.KPC-producing Klebsiella pneumoniae (KPC-Kp) raises major concerns in the context of intensive care, owing to limited treatment options and the ability to cause outbreaks in this specific setting. The objectives of this review are to give an overview of the burden of KPC-Kp in ICU patients and to discuss methodological issues and limitations regarding the quality of data available. Robust and reliable assessment of the KPC-Kp impact in the ICU should take into consideration not only characteristics of the individuals, but also of the health systems including length of stay, costs and hospital organization issues. Estimates of mortality reported in the current literature are weakened by the poor quality of adjustment for age-specific risks, co-morbidities, and appropriateness of therapy. All these confounding factors should be taken into account in models, with consideration of control groups and competing risks that is currently lacking in the published literature. Since development of antibiotic resistance is an unstoppable phenomenon and economic and human resources are facing progressive limitations due to budget constraints, cost-saving strategies targeted to avoid ICU closure, temporary limitation of admissions or delayed hospital discharge are necessary. The early identification of KPC-Kp-colonized patients through active screening strategies is likely to be the cornerstone of such a cost-saving strategy. However, there are still many open issues concerning which of these strategies are the most effective. Owing to extreme heterogeneity and several methodological flaws in current publications, future studies investigating the long-term sequelae and economic impact of KPC-Kp in the ICU are urgently needed.The aim of the current study was to investigate trends in frailty and its relationship with mortality among older adults aged 64-84 years across a period of 21 years. Data from 1995 to 2016 were used from the Longitudinal Aging Study Amsterdam. A total of 7,742 observations of 2,874 respondents in the same age range (64-84 years) across six measurement waves were included. Frailty was measured with a 32-item frailty index, with a cut-point of ≥0.25 to indicate frailty. The outcome measure was 4-year mortality. Generalized Estimating Equation analyses showed that among older adults aged 64-84 years the 4-year mortality rate declined between 1995 and 2016, while the prevalence of frailty increased. Across all measurement waves, frailty was associated with 4-year mortality (Odds Ratio 2.79, 95% Confidence Interval 2.39, 3.26). There was no statistically significant interaction effect between frailty and time on 4-year mortality, indicating a stable association between frailty and mortality. link= EGFR phosphorylation In more recent generations of older adults, frailty prevalence rates were higher, while excess mortality rates of frailty remained the same. This is important information for health policy makers and clinical practice, as it shows that continued efforts are needed to reduce frailty and its negative health consequences.
Thyroid hormones (THs) influence hepatic lipid homeostasis through multiple pathways, suggesting that THs may predict the risk of non-alcoholic fatty liver disease (NAFLD). However, prospective studies on the association between THs levels and incident NAFLD in euthyroid subjects are limited. link2 This prospective cohort study aimed to explore whether THs were associated with the development of NAFLD in middle-aged and elderly euthyroid subjects.

A total of 6,462 subjects without baseline NAFLD were included in the cohort study (~6-year follow-up period, median 4.2 years). Chemiluminescence immunoassay was used to measure serum free triiodothyronine (FT3), free thyroxine (FT4), and thyroid-stimulating hormone (TSH), and NAFLD was diagnosed by abdominal ultrasonography. Multivariable Cox proportional hazards regression models were used to assess the association between baseline THs, TSH, and the risk of NAFLD.

During the follow-up period, 1,675 subjects developed NAFLD. The incidence rate of NAFLD was 85.0 per 1000 person-years. Compared with the lowest FT3, FT4, and TSH quartiles, the multivariable-adjusted hazard ratios (95% confidence interval) of incident NAFLD for highest quartiles were 1.30 (1.12, 1.51), 1.07 (0.93, 1.23), 0.82 (0.71, 0.95) (P <0.001, =0.56, =0.01, respectively), respectively.

In middle-aged and elderly euthyroid subjects, high-normal FT3 and low-normal TSH are independently associated with a higher incidence of NAFLD.

This cross-sectional study used data from the Study of Cardiovascular Risk Factors in Adolescents (ERICA), conducted in 36,956 adolescents in 2013/2014. The relationship between food consumption away from home and each target outcome (hypertriglyceridemia, hypercholesterolemia, hyperglycemia, high glycated hemoglobin, and hyperinsulinemia) was tested with logistic regression models adjusted for age, school system (public versus private), physical activity, and screen time. Data on food consumption were obtained with a 24-hour diet recall (24HR), analyzing consumption of energy, added sugar, sodium, potassium, fiber, fruits, vegetables, rice, beans, sandwiches, cakes, dessert, chocolates, and sodas. The results showed that 53.2% of adolescents consumed foods away from home. Eating away from home showed an inverse relationship with hyperinsulinemia (OR = 0.65; 95%CI 0.46-0.92) and hyperglycemia (OR = 0.46; 95%CI 0.30-0.71) in boys and hypertension (OR = 0.71; 95%CI 0.55-0.92) and hyperglycemia (OR = 0.57; 95%CI 0.34-0.96) in girls. link3 However, the consumption of calories, added sugar, sandwiches, desserts, and sodas was higher in adolescents that consumed foods away from home. The protective role of eating away from home, as measured by biochemical indicators in adolescents, may be a function of higher consumption of school meals, which was more frequent among adolescents that consumed food away from home, thus highlighting the importance of encouraging consumption of school meals.Sensitive assay of EGFR T790M, a circulating tumor DNA marker in non-small-cell carcinoma, provides critical information for the decision of clinical treatments, evaluation of radiotherapy effect, and monitoring the progress of recurrence and metastasis. In this report, a novel flow cytometry-based sensing method is proposed for detecting T790M. The toehold-sequence hybridizes with the biotin-labeled initiator sequence and forms IT-dsDNA. The presence of a target induces the displacement of initiator-sequence from IT-dsDNA. The targets are continuously set free with the aid of a helper hairpin sequence for the next cycle. In tandem, the free initiator sequence starts the hybridization chain reaction, which binds the serial of fluorescence-labeled probe sequences. The products of the hybridization chain reaction are captured and separated by magnetic beads, which are finally assayed via flow cytometry. The capability to distinguish single-nucleotide polymorphism and the tolerance of complex matrix in blood serum indicate that this strategy has the promising potential to be applied in the liquid biopsy of clinical samples.
