Characteristics of nursing homes with high rates of invasive methicillin-resistant Staphylococcus aureus infections.

Background: Nursing home residents experience a large burden of invasive methicillin-resistant Staphylococcus aureus (MRSA) infections. Data are limited regarding nursing home characteristics associated with differences in facility-level invasive MRSA rates.

Methods: We analyzed 2011-2015 data from CDC's Emerging Infections Program (EIP) active population- and laboratory-based surveillance for invasive MRSA cases within seven states.

Prediction of post-treatment recurrence in early-stage breast cancer using deep-learning with mid-infrared chemical histopathological imaging.

Predicting long-term recurrence of disease in breast cancer (BC) patients remains a significant challenge for patients with early stage disease who are at low to intermediate risk of relapse as determined using current clinical tools. Prognostic assays which utilize bulk transcriptomics ignore the spatial context of the cellular material and are, therefore, of limited value in the development of mechanistic models. In this study, Fourier-transform infrared (FTIR) chemical images of BC tissue were used to train deep learning models to predict future disease recurrence.

Soluble CD52 mediates immune suppression by human seminal fluid.

Seminal fluid provides for the carriage and nutrition of sperm, but also modulates immunity to prevent allo-rejection of sperm by the female. Immune suppression by seminal fluid has been associated with extracellular vesicles, originally termed prostasomes, which contain CD52, a glycosylated glycophosphoinositol-anchored peptide released from testicular epithelial cells. Previously, we reported that human T cell-derived CD52, bound to the danger-associated molecular pattern protein, high mobility group box 1 (HMGB1), suppresses T cell function via the inhibitory sialic acid-binding immunoglobulin-like lectin-10 (Siglec-10) receptor.

Therapeutic Persistence in the Management of Familial Hypercholesterolemia: A Case of Acquired PCSK9 Inhibitor Nonresponse.

Familial hypercholesterolemia (FH) is an inherited disorder of lipid metabolism that causes marked elevations in low-density lipoprotein cholesterol and is associated with premature atherosclerotic cardiovascular disease. A 71-year-old woman with FH, established atherosclerotic cardiovascular disease, and statin intolerance presents to the cardiology clinic to discuss lipid management. Despite having failed combinations of statins, ezetimibe, and 2 proprotein convertase subtilisin/kexin type 9 inhibitors that use monoclonal antibodies, she was able to achieve low-risk low-density lipoprotein cholesterol levels using a novel way to lower proprotein convertase subtilisin/kexin type 9 levels with inclisiran.

Validation and Performance of Quantitative BRCA1 and RAD51C Promoter Hypermethylation Testing in Breast and Ovarian Cancers.

Poly (adenosine diphosphate-ribose) polymerase (PARP) inhibitors represent a significant advancement in the treatment of epithelial ovarian cancer, triple-negative breast cancer, pancreatic cancer, and castrate-resistant prostate cancer, and they are poised to improve treatment in an increasing number of other cancer types. PARP inhibitor efficacy as monotherapy has been primarily observed in tumors with deleterious genetic variants in genes involved in the homologous recombination repair pathway. Tumors without these variants have also been shown to respond; notably, those with hypermethylation at all alleles of the BRCA1 or RAD51C promoter can respond to PARP inhibitors.

Top 10 Tips for Using Statins in Clinical Practice.

Statins are the mainstay of cholesterol treatment to prevent atherosclerotic cardiovascular disease. However, significant barriers, including physician and patient factors, prevent the optimal use of this drug class. In this article, we provide 10 clear and simple tips for clinicians when prescribing statins.

Optimising Shifted Excitation Raman Difference Spectroscopy (SERDS) for application in highly fluorescent biological samples, using fibre optic probes.

Fibre optic probe based Raman spectroscopy can deliver molecular compositional analysis of a range of diseases. However, some biological tissues exhibit high levels of fluorescence which limit the utility of the technique, particularly when the fluorescence induces CCD etaloning, which can be particulalry hard to remove in subsequent analysis. Furthermore, use of fibre probes can result in silica signals superimposed on the biological Raman signals.

Strengthening Academic Public Health Programs and Workforce Development Through Fieldwork: Insights From a Novel Partnership Between New Mexico's Two Major Universities.

Our collaboration to strengthen applied practice in public health training between two public universities in New Mexico has offered us insight into the types of institutional, administrative, and programmatic support beneficial for navigating work with limited resources and varying geographic considerations. We share some lessons from this burgeoning partnership between University of New Mexico's (UNM) College of Population Health and New Mexico State University's (NMSU) Department of Public Health Sciences which began in 2022. The main areas of learning focus on exchanging resources to extend relationships with fieldwork sites and site supervisors, engage and support students in their planning and implementation of their fieldwork, and identify institutional resources to maintain and grow programmatic quality.

UK guidelines for the investigation and management of eosinophilia in returning travellers and migrants.

Eosinophilia is a common finding in returning travellers, migrants and other travelling groups. In this setting it often indicates an underlying helminth infection. Infections associated with eosinophilia are frequently either asymptomatic or associated with non-specific symptoms but some can cause severe disease.

System transferability of Raman-based oesophageal tissue classification using modern machine learning to support multi-centre clinical diagnostics.

Background: The clinical potential of Raman spectroscopy is well established but has yet to become established in routine oncology workflows. One barrier slowing clinical adoption is a lack of evidence demonstrating that data taken on one spectrometer transfers across to data taken on another spectrometer to provide consistent diagnoses.

Methods: We investigated multi-centre transferability using human oesophageal tissue.

Enhanced Extreme Mass Ratio Inspiral Rates and Intermediate Mass Black Holes.

Extreme mass ratio inspirals (EMRIs) occur when stellar-mass compact objects begin a gravitational wave (GW) driven inspiral into massive black holes. EMRI waveforms can precisely map the surrounding spacetime, making them a key target for future space-based GW interferometers such as LISA, but their event rates and parameters are massively uncertain. One of the largest uncertainties is the ratio of true EMRIs (which spend at least thousands of orbits in the LISA band) and direct plunges, which are in-band for at most a handful of orbits and are not detectable in practice.

Identification of tauopathy-associated lipid signatures in Alzheimer's disease mouse brain using label-free chemical imaging.

There is cumulative evidence that lipid metabolism plays a key role in the pathogenesis of various neurodegenerative disorders including Alzheimer's disease (AD). Visualising lipid content in a non-destructive label-free manner can aid in elucidating the AD phenotypes towards a better understanding of the disease. In this study, we combined multiple optical molecular-specific methods, Fourier transform infrared (FTIR) spectroscopic imaging, synchrotron radiation-infrared (SR-IR) microscopy, Raman and stimulated Raman scattering (SRS) microscopy, and optical-photothermal infrared (O-PTIR) microscopy with multivariate data analysis, to investigate the biochemistry of brain hippocampus in situ using a mouse model of tauopathy (rTg4510).
