Cell Fate: What's Evolution Got to Do With It?

Theoretical frameworks concerning cell fate typically center on proximate causes to explain how cells know what type they are meant to become. While major advances in cell fate theory have been achieved by these mechanism-focused frameworks, there are some aspects of cell decision-making that require an evolutionary interpretation. While mechanistic biologists sometimes turn to evolutionary theory to gain insights about cell fate (cancer is a good example), it is not entirely clear in cell fate theory what insights evolutionary theory can add, and why in some cases it is required for understanding cell fate.

Job Satisfaction for Caregivers and Other Employees in Innovative Long-Term Care Homes for Residents With Cognitive Problems.

New housing models have emerged in Europe, Australia, the United States, and Canada. Intended for individuals with neurocognitive disorders, these models are characterized by a philosophy centered on the person, self-determination, liberty of choice, flexibility of care, acceptance of risk, and autonomy. Work and care are organized according to the pace and preferences of residents.

The OptimaMed intervention to reduce medication burden in nursing home residents with severe dementia: results from a pragmatic, controlled study.

Background: Nursing home (NH) residents with severe dementia use many medications, sometimes inappropriately within a comfort care approach. Medications should be regularly reviewed and eventually deprescribed. This pragmatic, controlled trial assessed the effect of an interprofessional knowledge exchange (KE) intervention to decrease medication load and the use of medications of questionable benefit among these residents.

Using a SPATIAL INS/GNSS MEMS Unit to Detect Local Gravity Variations in Static and Mobile Experiments: First Results.

In this study, we present the feasibility of using gravity measurements made with a small inertial navigation system (INS) during in situ experiments, and also mounted on an unmanned aerial vehicle (UAV), to recover local gravity field variations. The INS operated is the SPATIAL one developed by Advanced Navigation, which has three-axis accelerometers. When the temperature bias is corrected, these types of INS are powerful enough to present the periodic signal corresponding to the solid Earth tides.

COVID-19 and Vaccination: Knowledge, Attitudes and Practices of People Working on Illegal Gold Mining Sites in French Guiana.

Introduction: French Guiana is a French territory bordering Brazil and Suriname where the COVID-19 pandemic has severely strained the French Guianese health system. The people working on illegal gold mining sites in French Guiana, also known as garimpeiros, are mainly of Brazilian origin. Their health conditions are precarious, they live under the radar of the surveillance system and therefore, assessment of their health is quite challenging.

The concepts and origins of cell mortality.

Organismal death is foundational to the evolution of life, and many biological concepts such as natural selection and life history strategy are so fashioned only because individuals are mortal. Organisms, irrespective of their organization, are composed of basic functional units-cells-and it is our understanding of cell death that lies at the heart of most general explanatory frameworks for organismal mortality. Cell death can be exogenous, arising from transmissible diseases, predation, or other misfortunes, but there are also endogenous forms of death that are sometimes the result of adaptive evolution.

Shared Decision-Making Training for Home Care Teams to Engage Frail Older Adults and Caregivers in Housing Decisions: Stepped-Wedge Cluster Randomized Trial.

Background: Frail older adults and caregivers need support from their home care teams in making difficult housing decisions, such as whether to remain at home, with or without assistance, or move into residential care. However, home care teams are often understaffed and busy, and shared decision-making training is costly. Nevertheless, overall awareness of shared decision-making is increasing.

A meteorological dataset of the West African monsoon during the 2016 DACCIWA campaign.

As part of the Dynamics-Aerosol-Chemistry-Cloud Interactions in West Africa (DACCIWA) project, extensive in-situ measurements of the southern West African atmospheric boundary layer (ABL) have been performed at three supersites Kumasi (Ghana), Savè (Benin) and Ile-Ife (Nigeria) during the 2016 monsoon period (June and July). The measurements were designed to provide data for advancing our understanding of the relevant processes governing the formation, persistence and dissolution of nocturnal low-level stratus clouds and their influence on the daytime ABL in southern West Africa. An extensive low-level cloud deck often forms during the night and persists long into the following day strongly influencing the ABL diurnal cycle.

Prioritization of indicators of the quality of care provided to older adults with frailty by key stakeholders from five canadian provinces.

Background: To meet the needs of older adults with frailty better, it is essential to understand which aspects of care are important from their perspective. We therefore sought to assess the importance of a set of quality indicators (QI) for monitoring outcomes in this population.

Methods: In this mixed-method study, key stakeholders completed a survey on the importance of 36 QIs, and then explained their ratings in a semi-structured interview.

The Ancient Origins of Death Domains Support the 'Original Sin' Hypothesis for the Evolution of Programmed Cell Death.

The discovery of caspase homologs in bacteria highlighted the relationship between programmed cell death (PCD) evolution and eukaryogenesis. However, the origin of PCD genes in prokaryotes themselves (bacteria and archaea) is poorly understood and a source of controversy. Whether archaea also contain C14 peptidase enzymes and other death domains is largely unknown because of a historical dearth of genomic data.

Family Medicine Supervisors' Preferences for Improving Their Teaching Skills in Senior Care.

Background And Objectives: Many clinical supervisors in family medicine feel ill-equipped to teach senior care to their family medicine residents (trainees). We therefore sought to explore their preferred learning strategies for improving their clinical and teaching skills with regard to senior care.

Methods: In this qualitative study, we conducted focus groups and interviews with supervisors from four family medicine clinics, to explore their preferred educational strategies.

Programmed cell death as a black queen in microbial communities.

Programmed cell death (PCD) in unicellular organisms is in some instances an altruistic trait. When the beneficiaries are clones or close kin, kin selection theory may be used to explain the evolution of the trait, and when the trait evolves in groups of distantly related individuals, group or multilevel selection theory is invoked. In mixed microbial communities, the benefits are also available to unrelated taxa.

Assessing the Quality of Care Provided to Older Persons with Frailty in Five Canadian Provinces, Using Administrative Data.

Nous avons examiné la qualité des soins fournis aux personnes âgées fragiles dans cinq provinces canadiennes à partir de données administratives sur la santé. Dans chaque province, nous avons considéré les personnes âgées fragiles en fonction de deux cohortes : les personnes décédées et les personnes vivantes. Des règles de décision ont été utilisées pour déterminer quelles personnes étaient frêles, soit celles résidant en établissement de soins de longue durée, qui étaient en phase terminale ou dont le profil correspondait à deux des sept domaines identifiés.

Cell Death in Evolutionary Transitions in Individuality.

Programmed cell death (PCD) in cell groups and microbial communities affects population structures, nutrient recycling, and sociobiological interactions. A less explored area is the role played by PCD in the emergence of higher-level individuals. Here, we examine how cell death impacted evolutionary transitions in individuality (ETIs).

A computerized and innovative tool to guide interdisciplinary assessment: Exploring the feasibility of the implementation of the Competency Assessment Tool (CAT).

Unlabelled: An electronic tool, the Competency Assessment Tool (CAT), was developed in order to guide interdisciplinary teams through clinical competency assessment.

Objectives: To support the implementation and perpetuation of the CAT, the objectives were: 1) document health and social service professionals' needs in order to support the use of the CAT; 2) identify the facilitating factors and those hindering the implementation of the CAT in a healthcare establishment; 3) identify strategies favoring the use of the CAT.

Participants: Health and social service professionals and doctors were recruited.

Engaging Caregivers in Health-Related Housing Decisions for Older Adults With Cognitive Impairment: A Cluster Randomized Trial.

Background And Objectives: Informal caregivers are rarely as involved as they want to be in the housing decisions of cognitively impaired older adults. Lack of awareness of available options and their benefits and risks may lead to decisions that do not reflect older adults' preferences, and to guilt and regret. We assessed the effect of training home care teams in interprofessional shared decision-making (SDM) on the proportion of caregivers who report being active in this decision.

OVLI-TA: An Unmanned Aerial System for Measuring Profiles and Turbulence in the Atmospheric Boundary Layer.

In recent years, we developed a small, unmanned aerial system (UAS) called OVLI-TA (Objet Volant Leger Instrumenté⁻Turbulence Atmosphérique) dedicated to atmospheric boundary layer research, in Toulouse (France). The device has a wingspan of 2.60 m and weighed 3.

Key stakeholders' views on the quality of care and services available to frail seniors in Canada.

Background: Frail seniors often receive ineffective care, which does not meet their needs. It is still unclear how healthcare systems should be redesigned to be more sensitive to the needs and values of frail seniors and their caregivers. We thus aimed to describe key stakeholders' perspectives on the current healthcare and services available to frail seniors.

The OptimaMed intervention to reduce inappropriate medications in nursing home residents with severe dementia: results from a quasi-experimental feasibility pilot study.

Background: Medication regimens in nursing home (NH) residents with severe dementia should be frequently reviewed to avoid inappropriate medication, overtreatment and adverse drug events, within a comfort care approach. This study aimed at testing the feasibility of an interdisciplinary knowledge exchange (KE) intervention using a medication review guidance tool categorizing medications as either "generally", "sometimes" or "exceptionally" appropriate for NH residents with severe dementia.

Methods: A quasi-experimental feasibility pilot study with 44 participating residents aged 65 years or over with severe dementia was carried out in three NH in Quebec City, Canada.

"Please listen to me": A cross-sectional study of experiences of seniors and their caregivers making housing decisions.

Background: Little is known about the decision-making experiences of seniors and informal caregivers facing decisions about seniors' housing decisions when objective decision making measures are used.

Objectives: To report on seniors' and caregivers' experiences of housing decisions.

Design: A cross-sectional study with a quantitative approach supplemented by qualitative data.

Gendered Pathways to Burnout: Results from the SALVEO Study.

Aim: Burnout is a pervasive mental health problem in the workforce, with mounting evidence suggesting ties with occupational and safety outcomes such as work injuries, critical events and musculoskeletal disorders. While environmental [work and non-work, work-to-family conflict (WFC)] and individual (personality) pathways to burnout are well documented, little is known about how gender comes to influence such associative patterns. The aim of the study consisted in examining gendered pathways to burnout.

What Do Clinical Supervisors Require to Teach Residents in Family Medicine How to Care for Seniors?

We assessed clinicians' continuing professional development (CPD) needs at family practice teaching clinics in the province of Quebec. Our mixed methodology design comprised an environmental scan of training programs at four family medicine departments, an expert panel to determine priority clinical situations for senior care, a supervisors survey to assess their perceived CPD needs, and interviews to help understand the rationale behind their needs. From the environmental scan, the expert panel selected 13 priority situations.

The 4-Celled Tetrabaena socialis Nuclear Genome Reveals the Essential Components for Genetic Control of Cell Number at the Origin of Multicellularity in the Volvocine Lineage.

Multicellularity is the premier example of a major evolutionary transition in individuality and was a foundational event in the evolution of macroscopic biodiversity. The volvocine chlorophyte lineage is well suited for studying this process. Extant members span unicellular, simple colonial, and obligate multicellular taxa with germ-soma differentiation.

Evolution of cytokinesis-related protein localization during the emergence of multicellularity in volvocine green algae.

Background: The volvocine lineage, containing unicellular Chlamydomonas reinhardtii and differentiated multicellular Volvox carteri, is a powerful model for comparative studies aiming at understanding emergence of multicellularity. Tetrabaena socialis is the simplest multicellular volvocine alga and belongs to the family Tetrabaenaceae that is sister to more complex multicellular volvocine families, Goniaceae and Volvocaceae. Thus, T.
