Universal screening or a universal risk assessment combined with risk-based screening for multidrug-resistant microorganisms upon admission:Comparing strategies

OBJECTIVE: Timely identification of patients who carry multidrug-resistant microorganisms (MDRO) is needed to prevent nosocomial spread to other patients and to the hospital environment. We aimed to compare the yield of a universal screening strategy upon admission to the currently installed universal risk assessment combined with risk-based screening upon admission. METHODS: This observational study was conducted within a prospective cohort study. From January 1, 2018, until September 1, 2019, patients admitted to our hospital were asked to participate. Nasal and perianal samples were taken upon admission and checked for the presence of MDRO. The results of the universal risk assessment and risk-based screening were collected retrospectively from electronic health records. RESULTS: In total, 1017 patients with 1069 separate hospital admissions participated in the study. Universal screening identified 38 (3.6%) unknown MDRO carriers upon admission (37 individual patients), all carrying extended-spectrum beta-lactamase-producing Enterobacterales. For 946 of 1069 (88.5%) patients, both the universal risk assessment and universal screening were performed. For 19 (2.0%) admissions, ≥1 risk factor was identified. The universal risk assessment identified one (0.1%) unknown carrier, compared to 37 out of 946 carriers for the universal screening (P&lt;0.001). Of the 37 carriers identified through the universal screening, 35 (94.6%) reported no risk factors. CONCLUSIONS: Our results show that in our low endemic setting, a universal screening strategy identified significantly more MDRO carriers than the currently implemented universal risk-assessment. When implementing a universal risk-assessment, risk factors should be carefully selected to be able to identify ESBL-E carriers. While the universal screening identified more MDRO carriers, further research is needed to determine the cost-effectiveness of this strategy.</p

Acquisition of multidrug-resistant Enterobacterales during international travel: A systematic review of clinical and microbiological characteristics and meta-analyses of risk factors

Background: International tourism increased from 25 million tourist arrivals in 1950 to over 1.3 billion in 2017. These travelers can be exposed to (multi) resistant microorganisms, may become colonized, and bring them back home. This systematic review aims to identify the carriage rates of multidrug-resistant Enterobacterales (MDR-E) among returning travelers, to identify microbiological methods used, and to identify the leading risk factors for acquiring MDR-E during international travel. Methods: Articles related to our research question were identified through a literature search in multiple databases (until June 18, 2019)-Embase, Medline Ovid, Cochrane, Scopus, Cinahl, Web of Science, and Google Scholar. Results: Out of 3211 potentially relevant articles, we included 22 studies in the systematic review, and 12 studies in 7 random-effects meta-analyses. Highest carriage rates of MDR-E were observed after travel to Southern Asia (median 71%), followed by travel to Northern Africa (median 42%). Carbapenemase-producing Enterobacterales (CPE) were identified in 5 out of 22 studies, from a few patients. However, in only eight out of 22 studies (36.4%) the initial laboratory method targeted detection of the presence of CPE in the original samples. The risk factor with the highest pooled odds ratio (OR) for MDR-E was travel to Southern Asia (pooled OR = 14.16, 95% confidence interval [CI] = 5.50 to 36.45), followed by antibiotic use during travel (pooled OR = 2.78, 95% CI = 1.76 to 4.39). Conclusions: Risk of acquiring MDR-E while travelling increases depending on travel destination and if antibiotics are used during travel. This information is useful for the development of guidelines for healthcare facilities with low MDR-E prevalence rates to prevent admission of carriers without appropriate measures. The impact of such guidelines should be assessed

Dynamics of Staphylococcus aureus in patients and the hospital environment in a tertiary care hospital in the Netherlands

Background: The dynamics of Staphylococcus aureus in patients and the hospital environment are relatively unknown. We studied these dynamics in a tertiary care hospital in the Netherlands. Methods: Nasal samples were taken from adult patients at admission and discharge. Isolates cultured from clinical samples taken before and during hospitalization from these patients were included. Environmental samples of patient rooms were taken over a three-year period. Finally, isolates from clinical samples from patients with an epidemiological link to S. aureus positive rooms were included. Staphylococcal protein A (spa) typing was performed. Results: Nasal samples were taken from 673 patients. One hundred eighteen (17.5%) were positive at admission and discharge, 15 (2.2%) patients acquired S. aureus during hospitalization. Nineteen patients had a positive clinical sample during hospitalization, 15.9% of the S. aureus were considered as from an exogenous source. One hundred and forty (2.8%) environmental samples were S. aureus positive. No persistent contamination of surfaces was observed. Isolates were highly diverse: spa typing was performed for 893 isolates, identifying 278 different spa types, 161 of these spa types were observed only once. Conclusion: Limited transmission could be identified between patients and the hospital environment, and from patient-to-patient. Exogenous acquisition was assumed to occur in 15% of clinical samples. Environmental contamination was infrequent, temporarily, and coincided with the strain from the patient admitted to the room at that time. MRSA was rare and not found in the environment.</p

An outbreak of ST307 extended-spectrum beta-lactamase (ESBL)-producing Klebsiella pneumoniae in a rehabilitation center: An unusual source and route of transmission

Objective: Nosocomial outbreaks due to multidrug-resistant microorganisms in rehabilitation centers have rarely been reported. We report an outbreak of extended-spectrum beta-lactamase (ESBL)-producing Klebsiella pneumoniae (ESBL-K. pneumoniae) on a single ward in a rehabilitation center in Rotterdam, The Netherlands.Design: Outbreak description.Setting: A 40-bed ward of a rehabilitation center in the Netherlands.Methods: In October 2016, 2 patients were found to be colonized by genetically indistinguishable ESBL-K. pneumoniae isolates. Therefore, an outbreak management team was installed, by whom a contact tracing plan was made. In addition to general outbreak measures, specific measures were formulated to allow continuation of the rehabilitation process. Also, environmental cultures were taken. Multiple-locus variable-number tandem-repeat analysis and amplification fragment-length polymorphism were used to determine strain relatedness. Selected isolates were subjected to whole-genome multilocus sequence typing.Results: The outbreak lasted 8 weeks. In total, 14 patients were colonized with an ESBL-K. pneumoniae, of whom 11 patients had an isolate belonging to

Timing and risk factors for clinical fractures among postmenopausal women: a 5-year prospective study

BACKGROUND: Many risk factors for fractures have been documented, including low bone-mineral density (BMD) and a history of fractures. However, little is known about the short-term absolute risk (AR) of fractures and the timing of clinical fractures. Therefore, we assessed the risk and timing of incident clinical fractures, expressed as 5-year AR, in postmenopausal women. METHODS: In total, 10 general practice centres participated in this population-based prospective study. Five years after a baseline assessment, which included clinical risk factor evaluation and BMD measurement, 759 postmenopausal women aged between 50 and 80 years, were re-examined, including undergoing an evaluation of clinical fractures after menopause. Risk factors for incident fractures at baseline that were significant in univariate analyses were included in a multivariate Cox survival regression analysis. The significant determinants were used to construct algorithms. RESULTS: In the total group, 12.5% (95% confidence interval (CI) 10.1–14.9) of the women experienced a new clinical fracture. A previous clinical fracture after menopause and a low BMD (T-score <-1.0) were retained as significant predictors with significant interaction. Women with a recent previous fracture (during the past 5 years) had an AR of 50.1% (95% CI 42.0–58.1) versus 21.2% (95% CI 20.7–21.6) if the previous fracture had occurred earlier. In women without a fracture history, the AR was 13.8% (95% CI 10.9–16.6) if BMD was low and 7.0% (95% CI 5.5–8.5) if BMD was normal. CONCLUSION: In postmenopausal women, clinical fractures cluster in time. One in two women with a recent clinical fracture had a new clinical fracture within 5 years, regardless of BMD. The 5-year AR for a first clinical fracture was much lower and depended on BMD

Two shades of Green? The electorates of GreenLeft and the Party for the Animals

The Netherlands has two electorally significant parties that might be considered to be part of the Green' family: GreenLeft and the Party for the Animals. These two parties appeal to different niches of the Green electorate, identified on the basis of issue dimensions, demographics, and their trust in government. GreenLeft tends to attract voters from the traditional Green niche: those with egalitarian, cosmopolitan, environmentalist, and libertarian values. The Party for the Animals attracts another type of Green voter: significantly less cosmopolitan and evincing lower levels of political trust.</p

Infant mortality in mid-19th century Amsterdam:Religion, social class, and space

This study uses a unique historical GIS dataset compiled from birth, death, and population register records for infants born in the city of Amsterdam in 1851 linked to micro‐level spatial data on housing, infrastructure, and health care. Cox's proportional hazards models and the concept of egocentric neighbourhoods were used to analyse the effects of various sociodemographic characteristics, residential environment, water supply, and health‐care variables on infant mortality and stillbirth. The analyses confirm the favourable position of the Jewish population with respect to infant mortality as found in other studies and show the unfavourable position of orthodox Protestant minorities. Infant mortality rate differences are much smaller between social classes than between religions. The exact role of housing and neighbourhood conditions vis‐a‐vis infant mortality is still unclear; however, we ascertained that effects of environmental conditions are more pronounced in later stages of infancy and less important in the early stages of infancy

Psychological determinants of pregnancy-related lumbo- pelvic pain: a prospective cohort study

Abstract Objective. To study whether pregnancy-related lumbopelvic pain outcomes at 36 weeks of gestation can be predicted by psychological determinants earlier in pregnancy. Design. Prospective cohort study. Setting. Nine midwifery practices in different regions of the Netherlands. Population. A cohort of 223 low-risk pregnant women in the Netherlands was followed from week 12 of gestation until 36 weeks of gestation. Methods. Both psychological determinants and lumbopelvic pain symptoms were investigated with a set of questionnaires at 12, 24 and 36 weeks of gestation. Psychological determinants were measured with the Perceived Stress Scale (PSS), the Symptom Checklist-90-Revised (SCL-90), the Pregnancy-related Anxiety Questionnaire (PRAQ), and the Utrecht Coping List (UCL). Lumbopelvic pain outcomes were measured with the Pregnancy Mobility Index (PMI) and the Overall Complaints Index (OCI). Main outcome measures. Lumbopelvic pain symptoms and their impact at 36 weeks of gestation. Results. There was a significant increase in scores on both the PMI and OCI across the three sampling occasions in pregnancy. Lumbopelvic pain outcomes showed significant associations with the psychological determinants perceived stress and recently perceived psychological and physical distress at all three times during pregnancy. Pregnancy-related anxiety was not a significant predictor of lumbopelvic pain outcomes, neither was coping. Conclusions. Lumbopelvic pain symptoms and their impact on daily activities at 36 weeks of gestation can be predicted by psychological determinants earlier in pregnancy; the combination of perceived stress and physical disability at 24 weeks of pregnancy seems to be the best predictor of disability in later pregnancy

Effect of novel endoscope cleaning brush on duodenoscope contamination

Background and aims:Current duodenoscope reprocessing protocols are insufficient to prevent contamination and require adaptations to prevent endoscopy-associated infections (EAI). This study aimed to investigate the effect of a new endoscope cleaning brush on the contamination rate of ready-to-use duodenoscopes. Methods:This retrospective before-and-after intervention study collected duodenoscope surveillance culture results from March 2018 to June 2022. Contamination was defined as ≥1 colony-forming units of gastrointestinal or oral microorganisms (MGO). In December 2020, an endoscope cleaning brush with a sweeper design was introduced as the intervention in the manual cleaning of duodenoscopes. A logistic mixed effects model was used to study the effects of the intervention. Results:Data were collected from 176 culture sets before the new brush's introduction and 81 culture sets after. Pre-introduction, culture sets positive with MGO comprised 45.5% (95% CI: 38.3%-52.8%, 80/176), decreasing to 17.3% (95% CI: 10.6%-26.9%, 14/81) after implementing the new brush. Compared to the former brush, duodenoscopes cleaned with the new brush had lower odds of contamination with MGO (aOR=0.25, 95% CI: 0.11-0.58, p=0.001).Conclusions:Use of the new brush in manual cleaning reduced contamination with MGO and is expected to prevent EAIs. These findings should be confirmed in future prospective randomized studies.</p

What works for irregular migrants in the Netherlands?</

This contribution provides an overview of the extent to which rehabilitation instruments and opportunities are accessible for irregular migrants who are serving a criminal sanction in the Netherlands. It shows that irregular migrants are largely excluded from criminal sanctions that have rehabilitation as a central aim and from rehabilitation opportunities that are provided during the implementation of criminal sanctions. These findings raise questions concerning the legal legitimacy of largely excluding irregular migrants from rehabilitation opportunities and the way in which irregular migrants prepare themselves for their return to society in practice
