This study explores the integration of Raman spectroscopy (RS) with machine learning for the early detection and subtyping of breast cancer using blood plasma samples. We performed detailed spectral analyses, identifying significant spectral patterns associated with cancer biomarkers. Our findings demonstrate the potential for classifying the four major subtypes of breast cancer at stage Ia with an average sensitivity and specificity of 90% and 95%, respectively, and a cross-validated macro-averaged area under the curve (AUC) of 0.

Assessing the fate of contaminants in the environment requires a deep understanding of intrinsic adsorption mechanisms on natural minerals such as Fe-oxyhydroxides. In this study, we proposed an innovative approach to probe site heterogeneities on the goethite surface by comparing the adsorption behavior of rare earth elements (REEs, including Sc, Y, and all lanthanides; Ln) except Pm, as well as Th and U. A surface loading-dependent adsorption of Ln and Y was observed, with a shift from (i) preferential middle to heavy REE adsorption and (ii) limited to substantial fractionation between Y and Ho as the loading increased.

Cumulative effects assessments are often expected to include an analysis of environmental and social effects despite a relative lack of clarity around how include a broad spectrum of social and cultural impacts. In Canda, these expectations are evolving in part in response to the need to consider the impacts of development on Indigenous communities, and the emergence of Indigenous-led Led Impact Assessment. Led by a team from the Tŝilhqot'in National Government and the University of British Columbia's Centre for Environmental Assessment Research, this project explored how to improve processes for assessing cumulative effects drawing from an Indigenous-led approach.

Per- and polyfluoroalkyl substances (PFAS) are ubiquitous environmental contaminants that often co-occur with heavy metals. Despite their prevalence, the mobility of PFAS in complex, multicomponent systems, particularly at the molecular scale, remains poorly understood. The vast diversity of PFAS and their low concentrations alongside anthropogenic and natural substances underscore the need for integrating mechanistic insights into the sorption models.

Article Synopsis
  • A systematic review was conducted to explore the issue of misdiagnosis in dementia, particularly focusing on rarer subtypes that may struggle more with accurate diagnosis compared to common types like Alzheimer's.
  • The review included 20 studies and identified four main themes: factors contributing to misdiagnosis, challenges in the diagnostic process, economic implications, and personal experiences of individuals facing delayed diagnoses.
  • There is a critical need for further research on the emotional and monetary effects of dementia misdiagnosis on patients, caregivers, and the healthcare system to improve clinical practices.

Background: Improvements in surgical techniques and perioperative care as well as increased patient life expectancies have led cardiothoracic surgeons to perform more complex operations, including reoperative open-heart surgeries. However, there is debate as to which patients are appropriate operative candidates for reoperative procedures.

Methods: This is a retrospective, single-center study of patients who underwent reoperative open-heart surgery via median sternotomy or thoracotomy over a 10-year period.

Oral cancer survival rates have seen little improvement over the past few decades. This is mainly due to late detection and a lack of reliable markers to predict disease progression in oral potentially malignant disorders (OPMDs). There is a need for highly specific and sensitive screening tools to enable early detection of malignant transformation.

Importance: Nudges have been increasingly studied as a tool for facilitating behavior change and may represent a novel way to modify the electronic health record (EHR) to encourage evidence-based care.

Objective: To evaluate the association between EHR nudges and health care outcomes in primary care settings and describe implementation facilitators and barriers.

Evidence Review: On June 9, 2023, an electronic search was performed in PubMed, Embase, PsycINFO, CINAHL, and Web of Science for all articles about clinician-facing EHR nudges.

Communication is an essential aspect of care for all patients but is especially important for individuals with Alzheimer's disease or other forms of dementia. Nurses who care for persons living with dementia (PwD), as well as family members and caregivers, need understanding of verbal and nonverbal communication techniques and approaches that are effective throughout the stages of dementia. Spiritual assessment and care also are critical.

Article Synopsis
  • Understanding how contaminants move through unsaturated soils is complex due to various physical and chemical processes influenced by water levels.
  • Experiments showed that the sand type and saturation levels affected how well birnessite (MnO) removed the antibiotic tetracycline (TTC), with moderate saturation in fine sand creating conditions that improved removal rates.
  • The study's findings contribute to better predictions of how redox-active contaminants behave in unsaturated environments by using transport models that account for adsorption and changes in water saturation.

Article Synopsis
  • The study investigates how freezing temperatures enhance the formation of soluble manganese(III) complexes from manganese(II) and manganese(IV) oxides in natural waters, focusing on the reactions occurring at ice boundaries.
  • It reveals that low salt conditions favor Mn(III) yields while high salt concentrations can affect the process differently by promoting complexation but ultimately reducing yield due to dehydration effects.
  • Repeated freeze-thaw cycles significantly increase dissolved Mn(III) concentrations, achieving up to 80% conversion after seven cycles, highlighting the importance of these reactions in high-latitude environments affected by freeze-thaw conditions.

Background: In this study, two fibrin sealant products, Fibrin Sealant Grifols (FS Grifols 80 mg/mL fibrinogen; 500 IU/mL thrombin) and Evicel (fibrinogen 55-85 mg/mL; thrombin 800-1200 IU/mL) were studied for efficacy in achieving hemostasis at a targeted bleeding site (TBS) on parenchymous or soft tissue in pediatric surgeries.

Methods: This phase 3, single-blind, active comparator, non-inferiority trial compared the number of patients achieving hemostasis at a TBS at four (T - primary endpoint), seven (T) and 10 (T) minutes after application, Safety and tolerability were assessed by recording adverse events during and after procedures. Eligible patients were <18 years old undergoing elective, open, non-cardiac thoracic, abdominal or pelvic surgeries.

This study investigates soil washing as a viable strategy to remove poly- and perfluoroalkyl substances (PFAS) from contaminated soils using various washing agents including water, methanol, ethanol, and cyclodextrin ((2-Hydroxypropyl)-β-cyclodextrin HPCD)). Water was less effective (removing only 30 % of PFAS), especially for long-chain hydrophobic PFAS. Methanol (50 % v/v) or HPCD (10 mg g soil) achieved > 95 % PFAS removal regardless of PFAS type, soil size fraction (0-400 µm or 400-800 µm), or experimental setups (batch or column, at liquid/solid (L/S) = 1).
