Profiling daptomycin resistance among diverse methicillin-resistant Staphylococcus aureus lineages in China

ABSTRACT Daptomycin (DAP) is effective against methicillin-resistant Staphylococcus aureus (MRSA). However, reduced susceptibility to DAP in MRSA may lead to treatment failures. We aim to determine the distribution of DAP minimum inhibitory concentrations (MICs) and DAP heteroresistance (hDAP) among MRSA lineages in China. A total of 472 clinical MRSA isolates collected from 2015 to 2017 in China were examined for DAP susceptibility. All isolates (n = 472) were found to be DAP susceptible, but 35.17% (166/472) of them exhibited a high DAP MIC (MIC >0.5 µg/mL). The high DAP MIC group contained a larger proportion of isolates with a higher vancomycin or teicoplanin MIC (>1.5 µg/mL) than the low DAP MIC group (19.3% vs 7.8%, P < 0.001; 22.3% vs 8.2%, P < 0.001). We compared the clonal complex (CC) distributions and clinical characteristics in MRSA isolates stratified by DAP MIC. CC5 isolates were less susceptible to DAP (MIC50 = 1 µg/mL) than CC59 isolates (MIC50 = 0.5 µg/mL, P < 0.001). Population analysis profiling revealed that 5 of 10 ST5 and ST59 DAP-susceptible MRSA isolates investigated exhibited hDAP. The results also showed that CC5 MRSA with an agrA mutation (I238K) had a higher DAP MIC than those with a wild-type agrA (P < 0.001). The agrA-I238K mutation was found to be associated with agr dysfunction as indicated by the loss of δ-hemolysin production. In addition, agr/psmα defectiveness was associated with hDAP in MRSA. Whole-genome sequencing analysis revealed mutations in mprF and walR/walK in DAP-resistant subpopulations, and most DAP-resistant subpopulations (6/8, 75%) were stable. Our study suggests that the increased DAP resistance and hDAP in MRSA may threaten the effectiveness against MRSA infections.
Transient response of an atmospheric GCM to North Atlantic SST anomalies

Abstract A high-resolution atmospheric general circulation model (GCM) is used to evaluate the atmospheric response to North Atlantic sea surface temperature (SST) anomalies. The transient evolution of the response is studied in detail. The linear and nonlinear effects can thus be contrasted and separated by their different time scales. Baroclinic patterns related directly to the surface anomalies quickly reach their maximum manifestation. However, barotropic patterns related to the mid- and upper troposphere eddy vorticity fluxes have longer time scales with much more important amplitude, able to gradually replace the initial baroclinic response. This study thus provides an evolutional picture of the two types of response in a GCM.
Acute hypoxia impairs posterior cerebral bioenergetics and memory in man

Hypoxia has the potential to impair cognitive function; however, it is still uncertain which cognitive domains are adversely affected. We examined the effects of acute hypoxia (∼7 h) on central executive (Go/No‐Go) and non‐executive (memory) tasks and the extent to which impairment was potentially related to regional cerebral blood flow and oxygen delivery (CDO2). Twelve male participants performed cognitive tasks following 0, 2, 4 and 6 h of passive exposure to both normoxia and hypoxia (12% O2), in a randomized block cross‐over single‐blinded design. Middle cerebral artery (MCA) and posterior cerebral artery (PCA) blood velocities and corresponding CDO2 were determined using bilateral transcranial Doppler ultrasound. In hypoxia, MCA DO2 was reduced during the Go/No‐Go task (P = 0.010 vs. normoxia, main effect), and PCA DO2 was attenuated during memorization (P = 0.005 vs. normoxia) and recall components (P = 0.002 vs. normoxia) in the memory task. The accuracy of the memory task was also impaired in hypoxia (P = 0.049 vs. normoxia). In contrast, hypoxia failed to alter reaction time (P = 0.19 vs. normoxia) or accuracy (P = 0.20 vs. normoxia) during the Go/No‐Go task, indicating that selective attention and response inhibition were preserved. Hypoxia did not affect cerebral blood flow or corresponding CDO2 responses to cognitive activity (P > 0.05 vs. normoxia). Collectively, these findings highlight the differential sensitivity of cognitive domains, with memory being selectively vulnerable in hypoxia.
Amazonian colonization from the Atlantic Forest: New perspectives on the connections of South American tropical forests

An open and dry vegetation belt separates Amazonia (AM) and the Atlantic Forest (AF). Evidence from palaeoclimatic and phylogenetic studies suggests past connections between these forests during cycles of increased humidity through the formation of forest corridors. The distinctive northern AF avifauna is known to have affinities both with AM and the southern AF. Still, the extent of how these two regions contributed to the assemblage of this avifauna remains poorly understood. Using historical demographic analyses and comparative phylogeography based on sub‐genomic genetic sampling, we assessed how past connections between AM and AF led to shared vicariance and colonization events in four avian AF endemic taxa. Our results supported the occurrence of humid forest corridors promoting the contact between AF and AM populations and suggested two vicariant events and two colonization events from AF to AM. Population divergences were mostly non‐synchronous and occurred multiple times during the Pleistocene. Historical gene flow was prevalent across study groups, supporting migration flows after the initial separation between AM and AF – a pattern previously unknown in birds between these regions. Idiosyncratic histories and divergent demographic syndromes suggest that organisms' responses to climate‐driven habitat shifts broadly depend on their ecological attributes. This study strengthened our knowledge of past connections between AM and AF and provided demographic scenarios amenable for testing in other groups of co‐distributed organisms.
Repeatability and Agreement of Chord Mu between Scheimpflug Tomography and Swept-Source Optical Coherence Tomography

Purpose To evaluate repeatability and agreement of chord mu between Scheimpflug tomography (Pentacam HR) and swept-source optical coherence tomography–based optical biometer (IOLMaster 700). Methods In this retrospective study, 63 eyes from 33 patients were included. Chord mu, X and Y Cartesian distances between the corneal vertex and the pupil center (Px and Py), and the pupil diameter were compared using two instruments. Repeatability was evaluated using intraclass correlation coefficient (ICC), coefficient of variation (CoV), and within-subject standard deviation (Sw). Interdevice agreement was evaluated using paired t-tests and Bland-Altman plots. Results Although Sw values for all parameters were similar between the two devices, CoV values of chord mu and pupil diameter were lower, and ICC values of those parameters were higher, in the IOLMaster 700 than in the Pentacam HR. Chord mu and pupil diameter values were higher in IOLMaster 700 than Pentacam HR (p < 0.01). The width of the 95% limit of agreement was wide for all parameters. Conclusions IOLMaster 700 showed better repeatability than Pentacam HR in chord mu, Px, Py, and pupil diameter values. Because there were statistically significant differences and a low level of agreement in chord mu and pupil diameter values between the two devices, they cannot be used interchangeably.
The use and access to contraception in Sweden during the COVID-19 pandemic period

Abstract Purpose Explore perceived access to, the need for, use of, and satisfaction with telemedicine services for contraceptive counselling and prescription-renewal-only during the COVID-19 pandemic, and the impact of the COVID-19 pandemic period on the choice and use of contraceptives. Materials and methods Internet-based e-survey of Swedish women of fertile age, 16–49 years. Results In total, 1016 participants completed the survey. Most participants (69.7%) rated their access to contraceptive services ‘as usual’. Among the remaining participants, a higher proportion rated their access as deteriorated (73.4%) compared to improved (26.6%; p < 0.001). In total, 38.0% reported a need for contraceptive counselling, whereof 14.0% had used telemedicine for counselling and reported high satisfaction. Telemedicine for prescription-renewal-only was used by 15.1% of the total population. Two per cent reported use of another contraceptive than their intended, whereof long-acting reversible contraceptives were the most common intended method. The proportion of current contraceptive users was lower than in 2017 (62.4% vs 71.1%, p < 0.001), and current users of long-acting reversible contraception decreased from 30.6% to 19.3% (p < 0.001). Conclusions During the COVID-19 pandemic period, most women found their access to contraceptive services unaffected, but more women felt that it had deteriorated than improved. The use of telemedicine was low, and the use of contraception overall fell. Efforts are needed to raise awareness of available services, and TM-provided interventions for maintained quality of care and informed decision-making remain to be evaluated. SHORT CONDENSATION The COVID-19 period imposed a change in contraceptive service provision, and efforts are needed to raise awareness of available services, including telemedicine. Access to all contraceptives, including LARCs, is crucial and telemedicine-provided interventions need evaluation.
Relative Risks for Dementia among Individuals with Glaucoma: A Meta-Analysis of Observational Cohort Studies

Purpose To investigate the relative risks (RRs) for dementia among individuals with glaucoma. Methods We conducted a search of PubMed, Web of Science, Scopus, and Cochrane databases for observational cohort studies examining the association between glaucoma and dementia until March 2023. Two authors independently screened all titles and abstracts according to predefined inclusion and exclusion criteria. Pooled RR and 95% confidence intervals (CIs) were generated using random-effect models. Results The meta-analysis included 18 cohort studies conducted in eight countries and involving 4,975,325 individuals. The pooled RR for the association between glaucoma and all-cause dementia was 1.314 (95% CI, 1.099–1.572; I2 = 95%). The pooled RRs for the associations of open-angle glaucoma with Alzheimer dementia and Parkinson disease were 1.287 (95% CI, 1.007–1.646; I2 = 96%) and 1.233 (95% CI, 0.677–2.243; I2 = 73%), respectively. The pooled RRs for the associations of angle-closure glaucoma with all-cause dementia and Alzheimer dementia were 0.978 (95% CI, 0.750–1.277; I2 = 17%) and 0.838 (95% CI, 0.421–1.669; I2 = 16%), respectively. No evidence of publication bias was detected in the Begg-Mazumdar adjusted rank correlation test (p = 0.47). Conclusions Based on current observational cohort studies, there is evidence supporting that glaucoma is a risk factor for dementia in the adult population.
Vascular Age Assessed From an Uncalibrated, Noninvasive Pressure Waveform by Using a Deep Learning Approach: The AI-VascularAge Model

BACKGROUND: Aortic stiffness, assessed as carotid-femoral pulse wave velocity, provides a measure of vascular age and risk for adverse cardiovascular disease outcomes, but it is difficult to measure. The shape of arterial pressure waveforms conveys information regarding aortic stiffness; however, the best methods to extract and interpret waveform features remain controversial. METHODS: We trained a convolutional neural network with fixed-scale (time and amplitude) brachial, radial, and carotid tonometry waveforms as input and negative inverse carotid-femoral pulse wave velocity as label. Models were trained with data from 2 community-based Icelandic samples (N=10 452 participants with 31 126 waveforms) and validated in the community-based Framingham Heart Study (N=7208 participants, 21 624 waveforms). Linear regression rescaled predicted negative inverse carotid-femoral pulse wave velocity to equivalent artificial intelligence vascular age (AI-VA). RESULTS: The AI-VascularAge model predicted negative inverse carotid-femoral pulse wave velocity with R2=0.64 in a randomly reserved Icelandic test group (n=5061, 16%) and R2=0.60 in the Framingham Heart Study. In the Framingham Heart Study (up to 18 years of follow-up; 479 cardiovascular disease, 200 coronary heart disease, and 213 heart failure events), brachial AI-VA was associated with incident cardiovascular disease adjusted for age and sex (model 1; hazard ratio, 1.79 [95% CI, 1.50–2.40] per SD; P<0.0001) or adjusted for age, sex, systolic blood pressure, total cholesterol, high-density lipoprotein cholesterol, prevalent diabetes, hypertension treatment, and current smoking (model 2; hazard ratio, 1.50 [95% CI, 1.24–1.82] per SD; P<0.0001). Similar hazard ratios were demonstrated for incident coronary heart disease and heart failure events and for AI-VA values estimated from carotid or radial waveforms. CONCLUSIONS: Our results demonstrate that convolutional neural network–derived AI-VA is a powerful indicator of vascular health and cardiovascular disease risk in a broad community-based sample.
Decisions regarding antibiotic prescribing for acute sinusitis in Norwegian general practice. A qualitative focus group study

Abstract Background Acute sinusitis is a frequent reason for primary care visits. Most patients recover within two weeks without antibiotic treatment. Despite this, about 50% of patients with acute sinusitis in Norwegian general practice are still prescribed antibiotics. We do not know the reason behind this discrepancy. Aim To explore the clinical decision-making process and reasons for treatment with antibiotics for acute sinusitis among Norwegian general practitioners (GPs). Methods Five focus group interviews were conducted (N = 25) in different parts of Norway, including GPs of various age, gender, and experience. The interviews were analysed using Systematic Text Condensation. Results The results showed a very diverse management of acute sinusitis among GPs, with decisions regarding antibiotics not always aligning with guideline recommendations. Many of the GPs did not agree with the Norwegian guidelines for antibiotics and chose something other than phenoxymethylpenicillin as their first choice. Clinical predictors emphasized in decision-making were pain complaints and patient exhaustion. Pragmatic factors such as weekday, travel plans, or a full waiting room could also influence the decision. Conclusion GPs found it difficult to identify when patients would benefit from antibiotic treatment for acute sinusitis, and different strategies were used to make prescribing decisions. For several GPs the degree of pain was one of the decisive reasons for antibiotic prescribing, however the guidelines for antibiotics do not give sufficient advice regarding pain treatment. These results suggest a need for revaluation of guideline contents and the way they are communicated to GPs. Key Points We know that antibiotics are often overused in the treatment of acute sinusitis, but there is lack of knowledge about the reasons behind GPs decision to prescribe them. There were considerable variations in clinical decision-making regarding the treatment of acute sinusitis among Norwegian GPs. The patients’ pain level, as well as pragmatic factors, were important deciding factors in the prescription of antibiotics. Guidelines for treatment regarding acute sinusitis may include more emphasis on pain management.
Outcomes and cost analysis of single-embryo transfer versus double-embryo transfer

Background: Studies had compared single-embryo transfer to double-embryo transfer with cleavage stage embryos and found that while single-embryo transfer was less costly, it was also associated with a lower live birth rate than double-embryo transfer. A single blastocyst transfer has been shown to improve the live birth rate per cycle compared to single-embryo transfer at cleavage stage. Objectives: To compare live birth rates and real costs of elective single-embryo transfer to double-embryo transfer and to determine the incremental cost-effectiveness ratio of these two strategies in an unselected pool of women in a single center. Design: Retrospective study. Methods: We analyzed data of 4232 women who underwent their first fresh in vitro fertilization/intra-cytoplasmic sperm injection cycles with at least two embryos available for transfer in KK Women’s and Children’s Hospital from 2010 to 2017. Results: Five hundred and sixty-four women underwent elective single-embryo transfer and 3668 women underwent double-embryo transfer. One hundred and fifty-six women who failed to achieve a live birth in their fresh elective single-embryo transfer cycle underwent a sequential thaw single-embryo transfer cycle. Live birth rate of fresh elective single-embryo transfer was significantly higher at 41.3% than that of double-embryo transfer at 32.6%. Cumulative live birth rate for sequential elective single-embryo transfer (fresh elective single-embryo transfer + thaw single-embryo transfer) was 47.9%. After accounting for variables which may affect live birth rates such as age and stage of embryo transfer, the odds of achieving a live birth from double-embryo transfer was 24% lower than that from sequential single-embryo transfer, although not statistically significant. For every live birth gained from an elective single-embryo transfer compared to double-embryo transfer, cost savings were S$20,172 per woman. If a woman had to have a sequential single-embryo transfer after a failed single-embryo transfer in her fresh cycle, cost savings were reduced to S$1476 per woman. Conclusion: Single-embryo transfer is a dominant strategy in an unselected population and adopting it in assisted reproductive treatments (ART) can produce cost savings without compromising on live birth rates.
Prediction of liver and lung metastases in patients with early‐onset colorectal cancer by nomograms based on heterogeneous and homogenous risk factors

Identifying the risk factors for distant metastasis in early‐onset colorectal cancer (EOCRC) is crucial for elucidating its etiology and facilitating preventive treatment. This study aims to characterize the variability in EOCRC incidence and discern both heterogeneous and homogeneous risk factors associated with synchronous liver, lung, and hepato‐lung metastases.
Dignity and the Importance of Acknowledgement of Personhood for People With Disability

Exploring the intricate relationship between individual and collective experiences, this study explores dignity from the perspectives of people with disability. Using an extreme citizen science approach, we engaged people with disability as active partners in gathering data through qualitative surveys and focus groups. Framework Analysis was employed to ensure the validity of findings while privileging the voices of people with lived experience of disability. Dignity was contingent on the acknowledgement of personhood and the delivery of human rights. Our research identified five key aspects to maintain and protect dignity: (1) acknowledging personhood; (2) recognising people with disability as decision-makers of their lives; (3) realising the right to access information; (4) maintaining the right to privacy; and (5) eliminating or minimising barriers to accessibility and inclusion. Undignified experiences that resulted from a lack of acknowledgement negatively affected participants’ wellbeing, and healthcare settings were identified as particularly challenging environments for dignity. These findings have significant implications for healthcare systems and services within an international and interdisciplinary context. They emphasise the need for adaptable, flexible services, co-designed with people with lived experience of disability. Addressing organisational constraints, resource limitations, and expectations is paramount to ensuring dignity is maintained through the acknowledgement of personhood and safeguarding of human rights.
Recursive solution to the multichannel filtering problem

Systems made up of arrays of sensors (seismographs, hydrophones, antennas, meteorological stations) receive geophysical data on a number of channels. Such multichannel data can be processed by means of a multichannel least-squares (Wiener) digital filter; the filter is determined by requiring that the sum of the mean-square errors between the desired outputs and the actual outputs for each channel be minimized. This requirement leads to a set of simultaneous linear equations, called the normal equations, where each element is itself a square matrix. The coefficients of the digital filter are given by the solution of these normal equations. An exact recursive procedure is derived for the numerical solution of the normal equations. In this recursive procedure advantage is taken of the fact that the matrix of the normal equations is an autocorrelation matrix, and hence is in the form of a Toeplitz matrix, namely one with equal elements along any diagonal. A set of auxiliary coefficients that are generated in the recursive procedure are the coefficients of matrix-valued polynomials which are the counterparts of the classical (scalar-valued) polynomials orthogonal on the unit circle. This set of auxiliary coefficients may also be used for a sideward recursion that corresponds to shifting the time index of the right-hand side of the normal equations. This sideward recursion is valuable in applications because it represents a relatively inexpensive way of determining the filter that incorporates the optimum time delay between the multichannel input signal and the multichannel output signal. The machine time required to solve the normal equations for a filter with m (matrix-valued) coefficients is proportional to m2 for the proposed recursive procedure, as compared with m3 for conventional techniques for the solution of simultaneous equations. Another advantage of using the recursive procedure is that it only requires computer storage space proportional to m, rather than to m2 as in the case of the conventional techniques.
Serum neurofilament light chain and cognition decline in US elderly: A cross‐sectional study

Early identification of cognitive impairment in neurodegenerative diseases like Alzheimer's disease (AD) is crucial. Neurofilament, a potential biomarker for neurological disorders, has gained attention. Our study aims to investigate the relationship between serum neurofilament light (sNfL) levels and cognitive function in elderly individuals in the United States.
