What You Are Hiding Could Be Hurting You: Autistic Masking in Relation to Mental Health, Interpersonal Trauma, Authenticity, and Self-Esteem.

Background: Autistic masking refers to some autistic individuals' tendency to hide, suppress, or camouflage their autistic traits, autistic identity, or autism diagnosis. Autistic masking also may include unconscious or conscious attempts to mimic the behavioral, cognitive, or sensory styles of nonautistic neurotypical people and to suppress natural forms of autistic behavior, cognition, and reactions to sensory experiences. Since autistic people are a stigmatized minority in many neurotypical dominated societies, passing as nonautistic through autistic masking may be an attempt to avoid autism stigma and a reaction to previous interpersonal trauma. Increased autistic masking behaviors are associated with reports of increased depression, anxiety, burnout, and exhaustion in autistic people, and thus, exploring the roots and impact of autistic masking is an important mental health topic. Methods: This study investigated the relationships between autistic masking and depression, anxiety, gender identity, sexual orientation, interpersonal trauma, self-esteem, authenticity, and autistic community involvement. Participants were autistic adults (n = 342) recruited through autistic social media groups. Results: This study found that higher self-reported autistic masking behaviors were associated with higher reports of past interpersonal trauma, greater anxiety and depression symptoms, lower self-esteem, lower authenticity, and lower participation within the autistic community. Autistic masking was not associated with gender identity or sexual orientation. Conclusions: The results of this study highlight the relationship between autistic masking and past interpersonal trauma, finding that autistic masking behavior is associated with mental health, self-esteem, and authenticity risks for autistic adults. We call into question the teaching of autistic masking strategies in therapies and education programs for autistic people based on the negative associations with autistic masking presented in this study and other research in this field.

Why is this an important issue? Autistic masking refers to autistic people suppressing their natural autistic traits, responses, and behaviors, in an attempt, consciously or unconsciously, to hide or reduce the visibility of their autistic traits, autistic identity, or autism diagnosis. High levels of autistic masking are associated with negative mental health, authenticity challenges, and burnout for autistic people. Interpersonal pressuring, past traumatic social experiences, and autism stigma potentially fuel autistic masking. What is the purpose of this study? This study aimed to investigate relationship between autistic masking and depression, anxiety, interpersonal trauma, self-esteem, authenticity, autistic community involvement, gender identity, and sexual orientation. What did the researchers do? We recruited 342 autistic adult participants through autistic social media groups on Facebook to complete a 30-minute anonymous survey online comprising validated scales to measure autistic masking, depression, anxiety, interpersonal trauma, self-esteem, and authenticity. Additional questions were asked about demographic factors, such as gender identity and sexual orientation, and we asked open-ended questions about past social trauma and intersectional issues. What were the results of the study? We found that higher self-reported autistic masking behaviors were associated with higher reports of past interpersonal trauma, specifically being shamed and teased about autistic traits, and broader experiences of emotional and physical abuse. Masking was also associated with greater anxiety and more depression symptoms, lower self-esteem, lower authentic living, greater accepting of external influence, higher self-alienation, and lower participation within the autistic community. Autistic masking was not found to be associated with gender identity or sexual orientation. Participants who reported involvement in previous applied behavior analysis therapy reported higher past interpersonal trauma than participants involved in some other forms of therapy such as cognitive behavior therapy. What do the findings add to what was already known? This study supports previous research associating autistic masking with depression and anxiety symptoms, and lower reported authenticity, such as autistic people feeling they were not being true to themselves, or revealing their genuine selves to others. This study is the first to quantitatively investigate relationships between autistic masking and past interpersonal traumas, self-esteem, authenticity, and autistic community involvement. What are potential weaknesses in the study? Our sample is not representative of the U.S. population when it comes to race, educational level, gender, and sexual orientation. It was very White, highly educated, had few cisgender men, and sixty three percent were members of sexual minority groups. The majority of participants reported late diagnosis of autism. This sample potentially contained an overrepresentation of people with high levels of autistic masking or who more recently realized they were autistic masking in comparison with the general autistic population. We did not analyze differences between early-diagnosed and late-diagnosed cohorts. How will these findings help autistic adults now or in the future? This research calls into question the teaching of autistic masking strategies in parenting, education, and therapy programs for autistic people based on the negative associations of autistic masking. Our findings should be utilized as a strong call to action to push back against practices that encourage autistic masking and autistic trait shaming. Instead we advocate for promoting forms of parenting, education, and therapy that respect autistic people's traits, communication styles, sensory needs, and autistic identity.

Nutritional and microbial profiles of ripened plant-based cheese analogs collected from the European market.

Plant-based cheese analogs have emerged as a novel global market trend driven by sustainability concerns for our planet. This study examines eleven soft ripened plant-based cheese analogs produced in Europe, primarily with bloomy rinds and cashew nuts as the main ingredient. First, we focused on exploring the macronutrients and salt content stated on the labels, as well a detailed fatty acid analysis of the samples. Compared to dairy cheeses, plant-based cheeses share similarities in lipid content, but their fatty acid profiles diverge significantly, with higher ratio of mono- and polyunsaturated fatty acids such as oleic and linoleic acids. We also investigated the microbiota of these analog products, employing a culture-dependent and -independent approaches. We identified a variety of microorganisms in the plant-based cheeses, with Lactococcus lactis and Leuconostoc mesenteroides being the dominant bacterial species, and Geotrichum candidum and Penicillium camemberti the dominant fungal species. Most of the species characterized are similar to those present in dairy cheeses, suggesting that they have been inoculated as culture starters to contribute to the sensorial acceptance of plant-based cheeses. However, we also identify several species that are possibly intrinsic to plant matrices or originate from the production environment, such as Pediococcus pentosaceus and Enterococcus spp. This coexistence of typical dairy-associated organisms with plant associated species highlights the potential microbial dynamics inherent in the production of plant-based cheese. These findings will contribute to a better understanding of plant-based cheese alternatives, enable the development of sustainable products, and pave the way for future research exploring the use of plant-based substrates in the production of cheese analogues.

Novel misos shape distinct microbial ecologies: opportunities for flavourful sustainable food innovation.

Fermentation is resurgent around the world as people seek healthier, more sustainable, and tasty food options. This study explores the microbial ecology of miso, a traditional Japanese fermented paste, made with novel regional substrates to develop new plant-based foods. Eight novel miso varieties were developed using different protein-rich substrates: yellow peas, Gotland lentils, and fava beans (each with two treatments: standard and nixtamalisation), as well as rye bread and soybeans. The misos were produced at Noma, a restaurant in Copenhagen, Denmark. Samples were analysed with biological and technical triplicates at the beginning and end of fermentation. We also incorporated in this study six samples of novel misos produced following the same recipe at Inua, a former affiliate restaurant of Noma in Tokyo, Japan. To analyse microbial community structure and diversity, metabarcoding (16S and ITS) and shotgun metagenomic analyses were performed. The misos contain a greater range of microbes than is currently described for miso in the literature. The composition of the novel yellow pea misos was notably similar to the traditional soybean ones, suggesting they are a good alternative, which supports our culinary collaborators' sensory conclusions. For bacteria, we found that overall substrate had the strongest effect, followed by time, treatment (nixtamalisation), and geography. For fungi, there was a slightly stronger effect of geography and a mild effect of substrate, and no significant effects for treatment or time. Based on an analysis of metagenome-assembled genomes (MAGs), strains of Staphylococccus epidermidis differentiated according to substrate. Carotenoid biosynthesis genes in these MAGs appeared in strains from Japan but not from Denmark, suggesting a possible gene-level geographical effect. The benign and possibly functional presence of S. epidermidis in these misos, a species typically associated with the human skin microbiome, suggests possible adaptation to the miso niche, and the flow of microbes between bodies and foods in certain fermentation as more common than is currently recognised. This study improves our understanding of miso ecology, highlights the potential for developing novel misos using diverse local ingredients, and suggests how fermentation innovation can contribute to studies of microbial ecology and evolution.

Recruitment and baseline data of the Aging and Cognitive Health Evaluation in Elders (ACHIEVE) study: A randomized trial of a hearing loss intervention for reducing cognitive decline.

INTRODUCTION: Hearing loss is highly prevalent among older adults and independently associated with cognitive decline. The Aging and Cognitive Health Evaluation in Elders (ACHIEVE) study is a multicenter randomized control trial (partially nested within the infrastructure of an observational cohort study, the Atherosclerosis Risk in Communities [ARIC] study) to determine the efficacy of best-practice hearing treatment to reduce cognitive decline over 3 years. The goal of this paper is to describe the recruitment process and baseline results. METHODS: Multiple strategies were used to recruit community-dwelling 70-84-year-old participants with adult-onset hearing loss who were free of substantial cognitive impairment from the parent ARIC study and de novo from the surrounding communities into the trial. Participants completed telephone screening, an in-person hearing, vision, and cognitive screening, and a comprehensive hearing assessment to determine eligibility. RESULTS: Over a 24-month period, 3004 telephone screenings resulted in 2344 in-person hearing, vision, and cognition screenings and 1294 comprehensive hearing screenings. Among 1102 eligible, 977 were randomized into the trial (median age = 76.4 years; 53.5% female; 87.8% White; 53.3% held a Bachelor's degree or higher). Participants recruited through the ARIC study were recruited much earlier and were less likely to report hearing loss interfered with their quality of life relative to participants recruited de novo from the community. Minor differences in baseline hearing or health characteristics were found by recruitment route (i.e., ARIC study or de novo) and by study site. DISCUSSION: The ACHIEVE study successfully completed enrollment over 2 years that met originally projected rates of recruitment. Substantial operational and scientific efficiencies during study startup were achieved through embedding this trial within the infrastructure of a longstanding and well-established observational study. Highlights: The ACHIEVE study tests the effect of hearing intervention on cognitive decline.The study is partially nested within an existing cohort study.Over 2 years, 977 participants recruited and enrolled.Eligibility assessed by telephone and in-person for hearing, vision, and cognitive screening.The ACHIEVE study findings will have significant public health implications.

Designing 3D multicomponent self-assembling systems with signal-passing building blocks.

We introduce an allostery-mimetic building block model for the self-assembly of 3D structures. We represent the building blocks as patchy particles, where each binding site (patch) can be irreversibly activated or deactivated by binding of the particle's other controlling patches to another particle. We show that these allostery-mimetic systems can be designed to increase yields of target structures by disallowing misassembled states and can further decrease the smallest number of distinct species needed to assemble a target structure. Next, we show applications to design a programmable nanoparticle swarm for multifarious assembly: a system of particles that stores multiple possible target structures and a particular structure is recalled by presenting an external trigger signal. Finally, we outline a possible pathway for realization of such structures at nanoscale using DNA nanotechnology devices.

Exploring the microbial diversity of novel misos with metagenomics.

Interest in fermented foods, especially plant-based ones, has increased considerably in the last decade. Miso-a Japanese paste traditionally fermented with soybeans, salt, and koji (Aspergillus oryzae grown on grains or beans)-has gained attention among chefs for its rich flavour and versatility. Some chefs have even been experimenting with making novel misos with untraditional substrates to create new flavours. Such novel fermented foods also offer new scientific opportunities. To explore the microbial diversity of these new traditional foods, we sampled six misos made by the team at a leading restaurant called Noma in Copenhagen (Denmark), using yellow peas (including a nixtamalised treatment), lupin seeds, Swedish Vreta peas, grey peas, and Gotland lentils as substrates. All misos were made with the same recipe and fermented for 3 months at 28 °C. Samples were collected at the end of fermentation for subsequent shotgun metagenomic sequencing and a genome-resolved metagenomic analysis. The taxonomic profile of the samples revealed the presence of koji mould (A. oryzae) and Bacillus amyloliquefaciens in all misos. Various species of the genera Latilactobacillus, Lactiplantibacillus, Pediococcus and Staphylococcus were also detected. The Metagenome-Assembled Genomes (MAGs) revealed genomic sequences belonging to 12 different species and functional analyses of these MAGs were performed. Notably, we detected the presence of Exiguobacterium-the first reported instance of the genus in miso-and Average Nucleotide Identity (ANI) analyses suggest a potentially new species. We hope these results will improve the scientific literature on misos and contribute to developing novel fermented plant-based foods.

"Doing What We Can with What We Have": Examining the Role of Local Government in Poverty Management during the COVID-19 Pandemic.

With the dawn of the COVID-19 pandemic and concern regarding the subsequent vulnerabilities of houseless populations, countries have sought to adapt and enhance emergency housing policies with a view of better protecting this population. Drawing on the poverty management perspective, this article focuses on local government and its role in managing houselessness during the COVID-19 pandemic. It achieves this by treating local council meetings as sites of problematization, in which the management of houselessness is rationalized and solutions negotiated. We transcribed local council meetings in Bristol, England and Edmonton, Canada, for an 18-month period from March 2020. Our analysis found that a common set of 'problem spaces' - systems, strategic opportunism and power - were evoked by municipal officials in both cities. Under the umbrella of 'doing what we can', local councils: conceptualized houselessness as complex and systemic; identified what does and does not work; discussed jurisdictional limitations and their impact; and defended new forms of accommodation. Significantly, despite the discursive desire to 'build back better', and a slightly rebalanced poverty management landscape in terms of care and control, local governments alone were unable to end houselessness within the post-COVID city.

Critical Hypophosphatemia in a Special Operations Combat Dive Candidate: A Case Report.

In contrast to shallow water (hypoxic) blackout and swimming-induced pulmonary edema (SIPE), acute electrolyte disturbance secondary to acute respiratory alkalosis is not considered a common Combat Swimmer injury but has the potential to be life-threatening. We present the case of a 28-year-old Special Operations Dive Candidate who presented to the Emergency Department after a near-drowning incident with altered mental status, generalized weakness, respiratory distress, and tetany. He was found to have severe symptomatic hypophosphatemia (1.00mg/dL) and mild hypocalcemia secondary to intentional hyperventilation between subsurface "cross-overs," causing subsequent acute respiratory alkalosis. This is a unique presentation of a common electrolyte abnormality in a highly specialized population that is self-limiting when caused by acute respiratory alkalosis but poses a significant danger to Combat Swimmers if rescue personnel are not able to respond quickly.

Bilateral Above the Knee Amputation in Afghanistan.

Prolonged Casualty Care (PCC) has become an essential component to Special Operations Forces (SOF) pre-mission training. However, it has not regularly been required in recent combat operations with the availability of medical evacuation (MEDEVAC) support. Poor weather conditions at an austere SOF outpost created an emergency unreachable by aeromedical evacuation. Herein, we report a case of an emergency bilateral above-the-knee amputation procedure performed by three Special Forces Medical Sergeants (18D(a), 18D(b), and 18D(c)) and supporting Army medics with minimal telemedicine consult and guidance.

Chemistry-Informed Machine Learning Enables Discovery of DNA-Stabilized Silver Nanoclusters with Near-Infrared Fluorescence.

DNA can stabilize silver nanoclusters (AgN-DNAs) whose atomic sizes and diverse fluorescence colors are selected by nucleobase sequence. These programmable nanoclusters hold promise for sensing, bioimaging, and nanophononics. However, DNA's vast sequence space challenges the design and discovery of AgN-DNAs with tailored properties. In particular, AgN-DNAs with bright near-infrared luminescence above 800 nm remain rare, placing limits on their applications for bioimaging in the tissue transparency windows. Here, we present a design method for near-infrared emissive AgN-DNAs. By combining high-throughput experimentation and machine learning with fundamental information from AgN-DNA crystal structures, we distill the salient DNA sequence features that determine AgN-DNA color, for the entire known spectral range of these nanoclusters. A succinct set of nucleobase staple features are predictive of AgN-DNA color. By representing DNA sequences in terms of these motifs, our machine learning models increase the design success for near-infrared emissive AgN-DNAs by 12.3 times as compared to training data, nearly doubling the number of known AgN-DNAs with bright near-infrared luminescence above 800 nm. These results demonstrate how incorporating known structure-property relationships into machine learning models can enhance materials study and design, even for sparse and imbalanced training data.

The dangers of the rabbit hole: Reflections on social media as a portal into a distorted world of edited bodies and eating disorder risk and the role of algorithms.

The relationship between social media usage and body image has been well-established in the literature; however, social media companies' use of algorithms may intensify this association, as algorithms provide viewers with personalized content that is often more extreme, less monitored, and designed to keep users engaged for longer periods of time. This article details the recent media coverage of algorithms, revelations by former social media employees regarding the problematic usage of algorithms, and revelations that social media companies are aware of the harm posed by their implementation of algorithms, particularly for young, vulnerable users. We provide recommendations for influencers, educators, researchers, clinicians, parents, and users, and conclude that it is ultimately the responsibility of the social media corporations to protect and enhance the well-being of their users.

Latent TB Infection in USSOF: A Refresher and Update.

Tuberculosis (TB) causes approximately 2 million deaths annually worldwide, with 2 billion persons estimated to be actively infected with TB. While rates of active TB disease in the US military are low, military service in TB-endemic countries remains an uncommon, but important source of infection. United States Special Operations Forces (USSOF) and enablers often operate in TB-endemic countries and, as an inherent risk of their mission sets, are more likely to have high-risk exposure to TB disease. Military medical authorities have provided excellent diagnostic guidance; the Centers for Disease Control and Prevention (CDC) recently updated preferred regimens for the treatment of latent TB infection (LTBI). This review serves as a refresher and update to the management of LTBI in USSOF to optimize medical readiness through targeted testing and short treatment regimens.

"Our Home Is a Muddy Structure": Perceptions of Housing and Health Risks Among Older Adults in Contrasting Neighborhoods in Ghana.

Aging occurs in a variety of social and physical environmental settings that affect health. However, despite their rapidly growing populations, public health research in sub-Saharan Africa has yet to address the role of residential environments in the health and well-being of older adults. In this study, we utilized an ethnographic research methodology to explore barriers and facilitators to health among older adults residing in two contrasting neighborhoods in Accra, Ghana. Our specific objective was to identify patterns of health risks among older adults in the two neighborhoods. Data were collected through qualitative interviews with a purposive sample of health workers (n = 5), community leaders (n = 2), and older adults residing in a slum and non-slum neighborhood (n = 30). Our thematic data analysis revealed that, despite different underlying drivers, health barriers across the slum and non-slum were largely similar. The harmful effects of these health barriers - poor built environments, housing precariousness, unsanitary living conditions, defective public services, and social incivilities - were mitigated by several facilitators to health, including affordable housing and social supports in the slum and better housing and appealing doors in the non-slum. Our study contributes to a more nuanced understanding of the ways in which aging and urban environments intersect to influence population health in resource poor settings. In particular, rather than the commonly referenced dichotomy of poor and non-poor settlements in discourses of neighborhood health, our findings point to convergence of health vulnerabilities that are broadly linked to urban poverty and governmental neglect of the elderly.

A descriptive pilot study of structural and functional social network ties among women in the women's health initiative (WHI) study.

Few studies examine the network structure and function of older women's health discussion networks. We sought to assess the feasibility and acceptability of collecting social network data via telephone from 72 women from the Women's Health Initiative study and to describe structural and functional characteristics. Women were socially connected and had dense networks. Women were emotionally close to network members, but their networks were not used to facilitate communication with health-care providers. One-third of network members was not influential on health-related decision-making. Collecting social network data via telephone is feasible and an acceptable, though un-preferred, mode of data collection.

Relative expression analysis of light-harvesting genes in the freshwater alga Lympha mucosa (Batrachospermales, Rhodophyta).

Members of the freshwater red algal order Batrachospermales are often described as shade-adapted. Nevertheless, recent ecophysiological studies have demonstrated species-level differences in acclimation to a range of irradiances. Lympha mucosa occurs in open and shaded portions of temperate streams and is abundant during summer months, suggesting it tolerates high and low irradiances. Specimens of L. mucosa were collected from open (sun-acclimated) or shaded (shade-acclimated) sites and exposed to low (<20 µmol photons · m-2 · s-1 ) or high (220 µmol photon · m-2 · s-1 ) light for 72 h to examine mechanisms of photoacclimation at the transcriptional level. High-throughput sequence data were used to design specific primers for genes involved with light harvesting and these were quantified with qPCR. The greatest significant difference in transcript abundances was observed in the psaA gene (Photosystem I P700 apoprotein), and site-type had an effect on these responses. Shade-acclimated thalli were 22-fold down-regulated at high light, whereas sun-acclimated thalli were only 5-fold down-regulated. Another gene involved with Photosystem I (petF ferredoxin) was down-regulated at high light, but only individuals from the shaded site were significantly different (4-fold). In thalli from both sites, cpeA (Phycoerythrin alpha chain) was down-regulated at high light. Although not statistically significant, patterns consistent with previous physiological and transcriptomic studies were uncovered, namely the inverse response of transcriptional activity in genes that encode phycobiliproteins. In support of previous ecophysiological studies of freshwater red algae, these data indicate significant transcriptional changes involving Photosystem I and phycobiliprotein synthesis are required to tolerate and grow at various irradiances.

DROIDS 3.0-Detecting Genetic and Drug Class Variant Impact on Conserved Protein Binding Dynamics.

The application of statistical methods to comparatively framed questions about the molecular dynamics (MD) of proteins can potentially enable investigations of biomolecular function beyond the current sequence and structural methods in bioinformatics. However, the chaotic behavior in single MD trajectories requires statistical inference that is derived from large ensembles of simulations representing the comparative functional states of a protein under investigation. Meaningful interpretation of such complex forms of big data poses serious challenges to users of MD. Here, we announce Detecting Relative Outlier Impacts from Molecular Dynamic Simulation (DROIDS) 3.0, a method and software package for comparative protein dynamics that includes maxDemon 1.0, a multimethod machine learning application that trains on large ensemble comparisons of concerted protein motions in opposing functional states generated by DROIDS and deploys learned classifications of these states onto newly generated MD simulations. Local canonical correlations in learning patterns generated from independent, yet identically prepared, MD validation runs are used to identify regions of functionally conserved protein dynamics. The subsequent impacts of genetic and/or drug class variants on conserved dynamics can also be analyzed by deploying the classifiers on variant MD simulations and quantifying how often these altered protein systems display opposing functional states. Here, we present several case studies of complex changes in functional protein dynamics caused by temperature, genetic mutation, and binding interactions with nucleic acids and small molecules. We demonstrate that our machine learning algorithm can properly identify regions of functionally conserved dynamics in ubiquitin and TATA-binding protein (TBP). We quantify the impact of genetic variation in TBP and drug class variation targeting the ATP-binding region of Hsp90 on conserved dynamics. We identify regions of conserved dynamics in Hsp90 that connect the ATP binding pocket to other functional regions. We also demonstrate that dynamic impacts of various Hsp90 inhibitors rank accordingly with how closely they mimic natural ATP binding.

On the outside looking in: Finding a place for managed alcohol programs in the harm reduction movement.

Alcohol policy in North America is dominated by moderation and abstinence-based modalities that focus on controlling population-level alcohol consumption and modifying individual consumption patterns to prevent and reduce alcohol-related harms. However, conventional alcohol policies and interventions do not adequately address harms associated with high-risk drinking among individuals experiencing severe alcohol use disorder (AUD) and structural vulnerability such as poverty and homelessness. In this commentary we address this gap in alcohol harm reduction, and highlight the lack of, and distinct need for, alcohol-specific harm reduction for people experiencing structural vulnerability and severe AUD. These individuals, doubly impacted by structural oppression and severe AUD, engage in various high-risk drinking practices that contribute to a unique set of harms that conventional abstinence-based treatments and interventions fail to adequately attend to. Managed alcohol programs (MAPs) have been established to address these multiple intersecting harms, and though gaining momentum across Canada, have had a hard time finding their place within the harm reduction movement. We illustrate how MAPs play a crucial role in the harm reduction movement in their ability to not only address high-risk drinking practices among structurally marginalized individuals, but to respond to harms associated with broader structural inequities such as poverty and homelessness.

Accounting for context: Social enterprises and meaningful employment for people with mental illness.

BACKGROUND: Many people living with mental illness want paid work, but finding and maintaining mainstream employment remains challenging. In recent decades, social enterprises have emerged as one alternative site for paid employment. Existing research has examined the experiences of people with mental illness working in social enterprises, but less is known about the organizational character of these workplaces. OBJECTIVE: The objective of this paper is to develop a better understanding of social enterprises as organizational contexts for workers with mental illness. METHODS: The research employed a qualitative methodology, conducting semi-structured interviews with executive directors and managers at 42 organizations operating 67 social enterprises across CanadaRESULTS:While there are strong similarities in organizational mandate to create meaningful employment there are also important variations between social enterprises. These include variations in size, economic activity and organizational structure, as well as differences in hours of work, rates of pay and the nature and extent of workplace accommodation. These variations reflect both immediate organizational contexts as well as broader economic constraints that enterprises confront. CONCLUSIONS: Understanding the varied nature of social enterprises is important for thinking about future enterprise development, and the capacity of such organizations to create meaningful employment for people living with mental illness.

Community managed alcohol programs in Canada: Overview of key dimensions and implementation.

INTRODUCTION AND AIMS: People with severe alcohol dependence and unstable housing are vulnerable to multiple harms related to drinking and homelessness. Managed Alcohol Programs (MAP) aim to reduce harms of severe alcohol use without expecting cessation of use. There is promising evidence that MAPs reduce acute and social harms associated with alcohol dependence. The aim of this paper is to describe MAPs in Canada including key dimensions and implementation issues. DESIGN AND METHODS: Thirteen Canadian MAPs were identified through the Canadian Managed Alcohol Program Study. Nine key informant interviews were conducted and analysed alongside program documents and reports to create individual case reports. Inductive content analysis and cross case comparisons were employed to identify six key dimensions of MAPs. RESULTS: Community based MAPs have a common goal of preserving dignity and reducing harms of drinking while increasing access to housing, health and social services. MAPs are offered as both residential and day programs with differences in six key dimensions including program goals and eligibility, food and accomodation, alcohol dispensing and administration, funding and money management, primary care services and clinical monitoring, and social and cultural connections. DISCUSSION AND CONCLUSIONS: MAPs consist of four pillars with the alcohol intervention provided alongside housing interventions, primary care services, social and cultural interventions. Availability of permanent housing and re-establishing social and cultural connections are central to recovery and healing goals of MAPs. Additional research regarding Indigenous and gendered approaches to program development as well as outcomes related to chronic harms and differences in alcohol management are needed.

Ottia meiospora (Ottiaceae, Rhodophyta), a new genus and family endophytic within the thallus of Nothocladus (Batrachospermales, Rhodophyta).

A new genus, Ottia, and family, Ottiaceae, are proposed within the Acrochaetiales to accommodate the uniseriate red algal endophyte of batrachspermalean taxa previously named Balbiania meiospora. Prior to this study, Balbiania investiens was transferred to its own family and order (Balbianiales) based on comparative DNA sequence data and a distinctive reproductive morphology. However, the second species described in this genus, B. meiospora, continued to be treated as a species of Audouinella (A. meiospora) pending further investigation. Phylogenetic analyses of sequence data confirmed only a distant relationship between the two endophytes, and a closer alliance of B. meiospora to Acrochaetiales. The data also showed that Ottia meiospora was the deepest diverging lineage in the Acrochaetiales, sister to all of the currently recognized genera and families. In this study, we review the classification of what we now call O. meiospora - reported from Australia, New Zealand and Brazil - based on sequence and morphological data. Morphological observations provided little clarity around the reproductive morphology or the life cycle of this endophyte of Nothocladus s. lat. found commonly in mainland Australia but, to date, less so in New Zealand.
