Structural characterization of the ACDC domain from ApiAP2 proteins, a potential molecular target against apicomplexan parasites.

The apicomplexan AP2 (ApiAP2) proteins are the best characterized family of DNA-binding proteins in Plasmodium spp. malaria parasites. Apart from the AP2 DNA-binding domain, there is little sequence similarity between ApiAP2 proteins.

Validation and safety of AmbuLatory care for transient ischemic attack from emergency department (VALID study).

Background: Transient Ischemic Attacks (TIAs) are a common reason for Emergency Department (ED) visits and represent a significant public health issue. Patients experiencing TIAs often face significant delays in undergoing various tests due to ED overcrowding and limited availability of neurologists. Emergency physicians (EPs) and neurologists have identified several criteria for allowing outpatient management.

Darolutamide in Combination With Androgen-Deprivation Therapy in Patients With Metastatic Hormone-Sensitive Prostate Cancer From the Phase III ARANOTE Trial.

Purpose: For patients with metastatic hormone-sensitive prostate cancer (mHSPC), delaying progression to castration-resistant disease is important not only for overall survival (OS) but also for patients' quality of life. Darolutamide plus androgen-deprivation therapy (ADT) with docetaxel improved OS versus ADT and docetaxel in patients with mHSPC. The ARANOTE trial evaluated darolutamide and ADT without chemotherapy in patients with mHSPC.

Oxygenation management during veno-arterial ECMO support for cardiogenic shock: a multicentric retrospective cohort study.

Backgound: Hyperoxemia is common and associated with poor outcome during veno-arterial extracorporeal membrane oxygenation (VA ECMO) support for cardiogenic shock. However, little is known about practical daily management of oxygenation. Then, we aim to describe sweep gas oxygen fraction (FO), postoxygenator oxygen partial pressure (PO), inspired oxygen fraction (FO), and right radial arterial oxygen partial pressure (PO) between day 1 and day 7 of peripheral VA ECMO support.

A versatile high-throughput assay based on 3D ring-shaped cardiac tissues generated from human induced pluripotent stem cell-derived cardiomyocytes.

We developed a 96-well plate assay which allows fast, reproducible, and high-throughput generation of 3D cardiac rings around a deformable optically transparent hydrogel (polyethylene glycol [PEG]) pillar of known stiffness. Human induced pluripotent stem cell-derived cardiomyocytes, mixed with normal human adult dermal fibroblasts in an optimized 3:1 ratio, self-organized to form ring-shaped cardiac constructs. Immunostaining showed that the fibroblasts form a basal layer in contact with the glass, stabilizing the muscular fiber above.

Purpose: This cross-sectional descriptive study describes available pelvic floor physiotherapy (PT) services for older women with urinary incontinence (UI) in Quebec, Canada, and identifies possible affordability barriers.

Methods: From September to December 2019, Quebec physiotherapists practising pelvic floor PT were invited to complete a survey on their clinical practice and perceptions of the affordability of UI treatment for older women.

Results: Eighty-four of the 225 registered pelvic floor physiotherapists (37.

Extended Safety and Tolerability of Darolutamide for Nonmetastatic Castration-Resistant Prostate Cancer and Adverse Event Time Course in ARAMIS.

Background: Patients with nonmetastatic castration-resistant prostate cancer (nmCRPC) are usually asymptomatic and seek treatments that improve survival but have a low risk of adverse events. Darolutamide, a structurally distinct androgen receptor inhibitor (ARi), significantly reduced the risk of metastasis and death versus placebo in ARAMIS. We assessed the extended safety and tolerability of darolutamide and the time-course profile of treatment-emergent adverse events (TEAEs) related to ARis and androgen-suppressive treatment.

Structural characterization of the ACDC domain from ApiAP2 proteins of the malaria parasite.

The Apicomplexan AP2 (ApiAP2) proteins are the best characterized family of DNA-binding proteins in the malaria parasite. Apart from the AP2 DNA-binding domain, there is little sequence similarity between ApiAP2 proteins and no other functional domains have been extensively characterized. One protein domain, which is present in a subset of the ApiAP2 proteins, is the conserved AP2-coincident domain mostly at the C-terminus (ACDC domain).

Online Group-based Pelvic Floor Muscle Training for Urinary Incontinence in Older Women: a Pilot Study.

Introduction And Hypothesis: Urinary incontinence (UI) is prevalent among older women, but conservative treatment rates remain low due to limited accessibility, despite evidence supporting pelvic floor muscle training (PFMT) efficacy. Group-based approaches, including online options, could offer cost-effective alternatives. Recent evidence supports the feasibility of online group-based PFMT for treating UI in older women.

Telemedicine in the primary care of older adults: a systematic mixed studies review.

Background: Family physicians had to deliver care remotely during the COVID-19 pandemic. Their efforts highlighted the importance of developing a primary care telemedicine (TM) model. TM has the potential to provide a high-quality option for primary care delivery.

Group-Based Pelvic Floor Telerehabilitation to Treat Urinary Incontinence in Older Women: A Feasibility Study.

Less than half of women with urinary incontinence (UI) receive treatment, despite the high prevalence and negative impact of UI and the evidence supporting the efficacy of pelvic floor muscle training (PFMT). A non-inferiority randomized controlled trial aiming to support healthcare systems in delivering continence care showed that group-based PFMT was non-inferior and more cost-effective than individual PFMT to treat UI in older women. Recently, the COVID-19 pandemic highlighted the importance of providing online treatment options.

A new multiplex SARS-CoV-2 antigen microarray showed correlation of IgG, IgA, and IgM antibodies from patients with COVID-19 disease severity and maintenance of relative IgA and IgM antigen binding over time.

Zoonotic spillover of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) to humans in December 2019 caused the coronavirus disease 2019 (COVID-19) pandemic. Serological monitoring is critical for detailed understanding of individual immune responses to infection and protection to guide clinical therapeutic and vaccine strategies. We developed a high throughput multiplexed SARS-CoV-2 antigen microarray incorporating spike (S) and nucleocapsid protein (NP) and fragments expressed in various hosts which allowed simultaneous assessment of serum IgG, IgA, and IgM responses.

Lectin microarray profiling demonstrates equivalent global glycosylation for whey protein ingredients enriched with α-lactalbumin and milk fat globule membrane.

Human milk fat globule membrane (MFGM) and whey proteins are nutritionally and functionally valuable, with many beneficial bioactivities associated with their glycosylation. However glycosylation of milk components other than free milk oligosaccharides are underinvestigated. Whey protein concentrate (WPC) ingredients with various enrichments or depletions are used in infant formula (IF) formulations to contribute to human milk equivalence and bioactivity benefits, but their overall or global glycosylation has not been compared.

Rural and urban differences in quality of dementia care of persons with dementia and caregivers across all domains: a systematic review.

Background: There are challenges in healthcare service delivery in rural areas, and this may be especially true for persons with dementia, who have higher needs to access to the healthcare system, and may have difficulties to commute easily and safely to these services. There is a growing body of literature regarding geographical disparities, but there is no comprehensive systematic review of geographical differences in persons with dementia across all domains of care quality. Therefore, the objective of this study is to conduct a systematic review of the literature on rural and urban differences in quality of dementia care outcomes of persons with dementia across all quality-of-care domains.

Feasibility, acceptability and effects of a group pelvic floor muscle telerehabilitation program to treat urinary incontinence in older women.

Introduction: Urinary incontinence (UI) is one of the most prevalent health concerns in women age 65 and over. The recommended first-line treatment for UI is individual pelvic floor muscle training (PFMT). However, healthcare systems worldwide are unable to meet the demand for this resource-intensive approach.

Efficacy and Safety of Darolutamide in Patients with Nonmetastatic Castration-resistant Prostate Cancer Stratified by Prostate-specific Antigen Doubling Time: Planned Subgroup Analysis of the Phase 3 ARAMIS Trial.

Background: Patients with nonmetastatic castration-resistant prostate cancer (nmCRPC) have a high risk of progression to metastatic disease, particularly if their prostate-specific antigen doubling time (PSADT) is ≤6 mo. However, patients remain at a high risk with a PSADT of >6 mo.

Objective: To evaluate the efficacy and safety of darolutamide versus placebo in patients stratified by PSADT >6 or ≤6 mo.

Is self-image, in reference to the gravitational vertical, altered in adolescent idiopathic scoliosis? A multicenter, single-blind, case-control study.

Purpose: Adolescent idiopathic scoliosis (AIS) is associated with perturbation of orthostatic postural control. In humans, orthostatic postural control is organized around the gravitational vertical (GV). Perception of the GV involves a bottom-up process (central integration of multisensorial information) and a top-down process that uses cognitive mechanisms relying on body image.

Improving dementia care: insights from audit and feedback in interdisciplinary primary care sites.

Background: Many primary care sites have implemented models to improve detection, diagnosis, and management of dementia, as per Canadian guidelines. The aim of this study is to describe the responses of clinicians, managers, and staff of sites that have implemented these models when presented with audit results, their insights on the factors that explain their results, their proposed solutions for improvement and how these align to one another.

Methods: One audit and feedback cycle was carried out in eight purposefully sampled sites in Ontario, Canada, that had previously implemented dementia care models.

Preparation and Fluorescent Labeling of Cell-Derived Micelles and Profiling on Glycan Microarrays.

Mammalian cell surface lectins mediate many important biological interactions which regulate physiological processes and therefore profiling mammalian cells on glycan microarray is of interest. However, many whole mammalian cells are not compatible with glycomics microarray formats and instead cell-derived micelles are prepared and profiled instead of whole cells as they can accurately represent the parental cell glycome. In this chapter, we describe the preparation of cell-derived micelles from mammalian cells, their labeling using a membrane-incorporating dye, and their profiling on a glycan microarray platform.

Mucin Purification and Printing Natural Mucin Microarrays.

Mucin glycosylation is the key facilitator of microbial attachment and nutrition and it varies according to biological location, health and disease status, microbiome composition, infection, and multiple other factors. Mucin glycans have also been reported to attenuate pathogen virulence and mediate biofilm dispersal. With the labor intensive and time-consuming purification required for natural mucins and their low quantitative yield from biological sources, natural mucin microarrays provide a convenient and multiplexed platform to study mucin glycosylation and interactions.

Calculating Half Maximal Inhibitory Concentration (IC) Values from Glycomics Microarray Data Using GraphPad Prism.

Half maximal inhibitory concentration (IC) is a measurement often used to compare the efficiency of various carbohydrates and their derivatives for inhibition of lectin binding to particular ligands. IC values can be calculated using experimental data from various platforms including enzyme-linked immunosorbent assay- (ELISA-)type microtiter plate assays, isothermal titration calorimetry (ITC), or glycan microarrays. In this chapter, we describe methods to fluorescently label a lectin, to carry out a lectin binding inhibition experiment on glycan microarrays, and to calculate the IC value of a binding inhibitory molecule using GraphPad Prism software.

Neoglycoprotein and Glycoprotein Printing on a Hydrogel Functionalized Microarray Surface and Incubation with Labeled Lectins.

Glycan microarrays are widely used to elucidate carbohydrate binding specificity and affinity of various analytes including proteins, microorganisms, cells, and tissues. Glycan microarrays comprise a wide variety of platforms, differing in surface chemistry, presentation of carbohydrates, carbohydrate valency, and detection strategies, all of which impact on analyte performance. This chapter describes detailed methods for printing neoglycoprotein and glycoprotein microarrays on hydrogel-coated slides and incubation of these glycan microarrays with fluorescently labeled lectins.

Randomness and Irreversiblity in Quantum Mechanics: A Worked Example for a Statistical Theory.

The randomness of some irreversible quantum phenomena is a central question because irreversible phenomena break quantum coherence and thus yield an irreversible loss of information. The case of quantum jumps observed in the fluorescence of a single two-level atom illuminated by a quasi-resonant laser beam is a worked example where statistical interpretations of quantum mechanics still meet some difficulties because the basic equations are fully deterministic and unitary. In such a problem with two different time scales, the atom makes coherent optical Rabi oscillations between the two states, interrupted by random emissions (quasi-instantaneous) of photons where coherence is lost.
