The contribution of an X chromosome QTL to non-Mendelian inheritance and unequal chromosomal segregation in Auanema freiburgense.

Auanema freiburgense is a nematode with males, females, and selfing hermaphrodites. When XO males mate with XX females, they typically produce a low proportion of XO offspring because they eliminate nullo-X spermatids. This process ensures that most sperm carry an X chromosome, increasing the likelihood of X chromosome transmission compared to random segregation. This occurs because of an unequal distribution of essential cellular organelles during sperm formation, likely dependent on the X chromosome. Some sperm components are selectively segregated into the X chromosome's daughter cell, while others are discarded with the nullo-X daughter cell. Intriguingly, the interbreeding of 2 A. freiburgense strains results in hybrid males capable of producing viable nullo-X sperm. Consequently, when these hybrid males mate with females, they yield a high percentage of male offspring. To uncover the genetic basis of nullo-spermatid elimination and X chromosome drive, we generated a genome assembly for A. freiburgense and genotyped the intercrossed lines. This analysis identified a quantitative trait locus spanning several X chromosome genes linked to the non-Mendelian inheritance patterns observed in A. freiburgense. This finding provides valuable clues to the underlying factors involved in asymmetric organelle partitioning during male meiotic division and thus non-Mendelian transmission of the X chromosome and sex ratios.

Course and outcome in individuals with atypical anorexia nervosa: Findings from the Study of Refeeding to Optimize iNpatient Gains (StRONG).

OBJECTIVE: We previously reported that participants with atypical anorexia nervosa (atypical AN) had higher historical and admission weights, greater eating disorder psychopathology, but similar rates of amenorrhea and weight suppression at baseline as compared to anorexia nervosa (AN); here, we compare 1-year outcomes. METHOD: Weight, % median body mass index (%mBMI), Eating Disorder Examination Questionnaire (EDE-Q) scores, resumption of menses, and rehospitalizations were examined at 3, 6, and 12 months post-discharge. Analyses (N = 111) compared changes in %mBMI, weight suppression, and EDE-Q scores over time between atypical AN and AN. RESULTS: Among the participants (48 atypical AN, 63 AN), both groups gained weight but those with atypical AN had lower gains than those with AN in %mBMI (p = .02) and greater weight suppression (p = .002) over time. EDE-Q scores improved over time, independent of weight suppression, with no significant difference between atypical AN and AN. Groups did not differ by rates of resumption of menses (80% atypical AN, 76.9% AN) or rehospitalization (29.2% atypical AN, 37.9% AN). Greater weight suppression predicted longer time to restore menses and more days of rehospitalization. DISCUSSION: Individuals with atypical AN regained a smaller proportion of body mass and were more weight suppressed over time. Change in eating disorder cognitions, resumption of menses, and rehospitalization rates at 1-year follow-up did not differ between groups. There was no significant difference in weight suppression between groups for those who were psychologically improved at 12 months. Findings highlight limitations in our understanding of weight recovery in atypical AN. New metrics for recovery are urgently needed. PUBLIC SIGNIFICANCE: Little is known about outcome in atypical anorexia nervosa (atypical AN). We examined recovery metrics in young people with atypical AN and anorexia nervosa (AN) 1 year after medical hospitalization. Individuals with atypical AN showed slower weight gain and remained further from their pre-illness weight. There were no differences in the rates of psychological recovery, resumption of menses, or rehospitalization. New metrics are needed to assess recovery in atypical AN.

From the international tobacco control arena to the local context: a qualitative study on the tobacco advertising, promotion and sponsorship legislative environment in Sudan and the challenges characterising it.

OBJECTIVES: The aim of the study was to assess the Sudanese tobacco advertising, promotion and sponsorship (TAPS) legislative environment and the challenges characterising it. We formulated three research questions: What is the TAPS policy context in Sudan? What circumstances led to the development of the current legislative text? Finally, what was the involvement of the different actors in these events? DESIGN: We conducted a qualitative analysis using the Health Policy Triangle model to frame the collection and extraction of publicly available information from academic literature search engines, news media databases or websites of national and international organisations, as published by February 2021. The thematic framework approach was employed to code and analyse the textual data and the generated themes were used to map connections across the data and to explore relationships among the generated subthemes and themes. SETTING: Sudan. DATA: Using a combination of the keywords "Sudan" and "tobacco advertising" (or "tobacco marketing" or "tobacco promotion"), we collected publicly available documents in the English language. We included 29 documents in the analysis. RESULTS: Three themes underpin the Sudanese legislative environment on TAPS: (1) limited and outdated TAPS data, (2) stakeholder involvement and tobacco industry interference and (3) TAPS legislation not aligned with the WHO Framework Convention on Tobacco Control Secretariat recommendations. CONCLUSIONS: Findings from this qualitative analysis suggest that recommendations to move forward in Sudan should include the systematic and periodic collection of TAPS surveillance data, addressing any remaining legislative content loopholes and protecting policy-making from tobacco industry interference. In addition, best practices from other low-income and middle-income countries with good TAPS monitoring systems, such as Egypt, Bangladesh and Indonesia, or with protective provisions against tobacco industry interference, such as Thailand and the Philippines, could be considered for adaptation and implementation.

Adolescents' Receipt of Care in a Medical Home: Results From a National Survey.

PURPOSE: Despite long-term emphasis on the medical home for children, little research focuses on adolescents. This study examines adolescent past-year attainment of medical home, its components, and subgroup differences among demographic and mental/physical health condition categories. METHODS: Utilizing the 2020-21 National Survey of Children's Health (NSCH), ages 10-17 (N = 42,930), we determined medical home attainment and its 5 components and subgroup differences utilizing multivariable logistic regression: sex; race/ethnicity; income; caregiver education; insurance; language spoken at home; region; and health conditions: physical, mental, both, or none. RESULTS: Forty-five percent had a medical home with lower rates among those who were as follows: not White non-Hispanic; lower income; uninsured; in non-English-speaking households; adolescents whose caregivers lacked a college degree; and adolescents with mental health conditions (p range = .01-<.0001). Differences for medical home components were similar. DISCUSSION: Given low medical home rates, ongoing differences and high mental illness rates, efforts are needed to improve adolescent medical home access.

Achieving a tobacco-free Bangladesh by 2040: a qualitative analysis of the tobacco advertising environment and prohibitions in Bangladesh.

OBJECTIVES: This paper explores the Bangladeshi tobacco advertising, promotion and sponsorship (TAPS) legislative environment, to highlight any potential policy loopholes and to facilitate the identification of additional provisions for inclusion. The study also aimed to identify valuable lessons applicable to other low-income and middle-income countries (LMICs). METHODS: We conducted a qualitative health policy analysis using the health policy triangle model to frame the collection and extraction of publicly available information from academic literature search engines, news media databases and websites of national and international organisations, published up until December 2020. We coded and analysed textual data using the thematic framework approach to identify themes, relationships and connections. RESULTS: Four themes underpin the Bangladesh legislative environment on TAPS: (1) engaging international actor interest in TAPS policies, (2) the incremental approach to TAPS policy-making, (3) time-sensitive TAPS monitoring data and (4) innovative TAPS monitoring and policy enforcement system. The findings highlight the role of international actors (such as multinational organisations and donors), tobacco control advocates and the tobacco industry in the policy-making process and the competing agendas they bring. We also outline the chronology of TAPS policy-making in Bangladesh and the existing loopholes and policy changes over time. Lastly, we describe the innovative approaches to TAPS monitoring and policy enforcement in Bangladesh to combat the tobacco industry marketing strategies. CONCLUSION: This study highlights the role of tobacco control advocates as crucial in TAPS policy-making, monitoring and enforcement in LMICs, and identifies good practices for the sustainability of tobacco control programmes. However, it also points out that tobacco industry interference, coupled with increasing pressure on advocates and legislators, may block progress in tobacco endgame approaches.

High potency cannabis use, mental health symptoms and cannabis dependence: Triangulating the evidence.

BACKGROUND: Cannabis potency (concentration of Δ-9-Tetrahydrocannabinol) has been associated with risks of adverse mental health outcomes and addiction but no studies have triangulated evidence from self-report and objective measures of cannabis potency. We hypothesised that users of high potency cannabis would have higher levels of (a) anxiety, (b) depression and (c) psychosis-like symptoms (d) cannabis dependence than users of lower potency cannabis. METHODS: A cross-sectional study of 410 participants donated a sample of cannabis for analysis of THC concentration and reported their cannabis potency preference. These two exposure measures were investigated for their association with cannabis dependence, depression, anxiety, and psychosis-like symptoms in separate linear/logistic regression models. RESULTS: High potency cannabis preference was associated with a slight increased risk of cannabis dependence after adjusting for confounding, with the exception of cannabis use frequency (OR = 1.16, 95% CI 1.04-1.28). No association was found between THC concentration in cannabis and cannabis dependence. There was weak evidence of a small association between cannabis potency and depression and anxiety. There was no association between high potency cannabis preference or THC concentration in cannabis and psychosis-like symptoms. CONCLUSIONS: Users of cannabis who preferred high potency types might be at increased risk of problematic cannabis use. This should be considered with caution as we were not able to triangulate these results with an objective measure of cannabis potency. More research is needed to understand the association between high potency cannabis use and depression and anxiety.

Hospital-based higher calorie refeeding and mealtime distress in adolescents and young adults with anorexia nervosa or atypical anorexia nervosa.

OBJECTIVE: The StRONG study demonstrated that higher calorie refeeding (HCR) restored medical stability faster in patients hospitalized with anorexia nervosa (AN) and atypical AN (AAN), with no increased safety events compared with standard-of-care lower calorie refeeding (LCR). However, some clinicians have expressed concern about potential unintended consequences of HCR (e.g., greater mealtime distress). The purpose of this study was to examine patient treatment preference and compare mealtime distress, food refusal, and affective states between treatments. METHOD: Participants (N = 111) in this multisite randomized clinical trial were ages 12-24 years, with AN or AAN, admitted to hospital with medical instability who received assigned study treatment (HCR or LCR). Treatment preference was assessed prior to randomization in the full sample. In a subset of participants (n = 45), linear mixed effect models were used to analyze momentary ratings of mealtime distress (pre, during, and post-meals) and daily affective state during the hospitalization. RESULTS: About half (55%) of participants reported a preference for LCR. Treatment assignment was not associated with food refusal, mealtime distress, or affective states in the subsample. Food refusal increased significantly over the course of refeeding (p = .018). Individuals with greater depression experienced more negative affect (p = .033), with worsening negative affect over time for individuals with higher eating disorder psychopathology (p = .023). DISCUSSION: Despite understandable concerns about potential unintended consequences of HCR, we found no evidence that treatment acceptability for HCR differed from LCR for adolescents and young adults with AN and AAN. PUBLIC SIGNIFICANCE: The efficacy and safety of higher calorie refeeding in hospitalized patients with anorexia nervosa has been demonstrated. However, it is not known whether higher calorie refeeding (HCR) increases meal-time distress. This study demonstrated that HCR was not associated with increased mealtime distress, food refusal, or affective states, as compared with lower calorie refeeding. These data support HCR treatment acceptability for adolescents/young adults with anorexia nervosa and atypical anorexia nervosa.

Tobacco advertising, promotion, and sponsorship ban adoption: A pilot study of the reporting challenges faced by low- and middle-income countries.

INTRODUCTION: The WHO Framework Convention for Tobacco Control (FCTC) Secretariat has identified issues with Article 13 (Tobacco Advertising, Promotion and Sponsorship) Party policy progress reporting, whilst some researchers remain skeptical of the completeness and accuracy of the data collected as part of the required reporting questionnaire. Gaining a deeper understanding of the challenges encountered when completing these questionnaires could provide insights to improve WHO FCTC progress reporting. METHODS: Qualitative semi-structured interviews were conducted between January and June 2021, with nine national tobacco control focal point (NFP) individuals (designates who report on WHO FCTC implementation on the Party's behalf) from low- and middle-income countries. The study analysis used a thematic framework approach involving data familiarization, thematic framework construction, indexing and refining, mapping and interpretation of the results. RESULTS: The analysis generated four themes: 1) use of different resources, 2) presence of compounding complexities, 3) use of supporting mechanisms employed for tackling the challenges, and 4) recommendations for refinements within the questionnaire and for those completing it. CONCLUSIONS: The WHO FCTC reporting questionnaire needs improvements that could be piloted and discussed between the Convention Secretariat and the Parties prior to wide scale implementation.

Effectiveness of Mental Health Warnings on Tobacco Packaging in People With and Without Common Mental Health Conditions: An Online Randomised Experiment.

Background: Health warning labels on tobacco packaging are a cost-effective means of health risk communication. However, while an extensive range of physical health risks are well-portrayed via current tobacco health warnings in the UK, there are none that currently portray the negative impact of smoking on mental health. Aims: (i) develop novel mental health warning labels for tobacco packaging and (ii) test perceptions of these warnings in smokers and non-smokers, with and without mental health problems. Methods: Six mental health warning labels were developed with a consultancy focus group. These warning labels were tested in an online randomised experiment, where respondents (N = 687) rated six Mental Health Warning Labels (MHWLs) and six Physical Health Warning Labels (PHWLs) on measures of perceived effectiveness, believability, arousal, valence, acceptability, reactance and novelty of information. Results: MHWLs were perceived as low to moderately effective (mean = 4.02, SD = 2.40), but less effective than PHWLs (mean = 5.78, SD = 2.55, p < 0.001, η p 2 = 0.63). MHWLs were perceived as less believable, arousing, unpleasant, and acceptable than PHWLs. MHWLs evoked more reactance and were rated as more novel. Perceptions of MHWLs did not differ in people with and without mental health problems except for reactance and acceptability, but consistent with the PHWL literature, perceptions of MHWLs differed between non-smokers and smokers. Conclusion: MHWLs could be an effective means to communicate novel information about the effects of smoking on mental health. MHWLs are perceived as less effective, believable, arousing, unpleasant, and acceptable than PHWLs, but MHWLs evoke more reactance and are rated as more novel.

Association of cannabis potency with mental ill health and addiction: a systematic review.

Cannabis potency, defined as the concentration of Δ9-tetrahydrocannabinol (THC), has increased internationally, which could increase the risk of adverse health outcomes for cannabis users. We present, to our knowledge, the first systematic review of the association of cannabis potency with mental health and addiction (PROSPERO, CRD42021226447). We searched Embase, PsycINFO, and MEDLINE (from database inception to Jan 14, 2021). Included studies were observational studies of human participants comparing the association of high-potency cannabis (products with a higher concentration of THC) and low-potency cannabis (products with a lower concentration of THC), as defined by the studies included, with depression, anxiety, psychosis, or cannabis use disorder (CUD). Of 4171 articles screened, 20 met the eligibility criteria: eight studies focused on psychosis, eight on anxiety, seven on depression, and six on CUD. Overall, use of higher potency cannabis, relative to lower potency cannabis, was associated with an increased risk of psychosis and CUD. Evidence varied for depression and anxiety. The association of cannabis potency with CUD and psychosis highlights its relevance in health-care settings, and for public health guidelines and policies on cannabis sales. Standardisation of exposure measures and longitudinal designs are needed to strengthen the evidence of this association.

Cross-sectional online survey of the impact of new tobacco health warnings in Colombia.

OBJECTIVES: This study aimed to explore the impact of a new set of six pictorial warnings introduced in 2018. DESIGN AND SETTING: Using a cross-sectional design, we examined awareness of the new warnings among Colombian smokers across two time points of data collection. PARTICIPANTS: Adult smokers (≥18 years of age), defined as having smoked at least 100 cigarettes in their lifetime and currently smoking at least one cigarette per week participated at time 1, prior to the introduction of the new health warnings in Colombia in 2018 (n=1985, 72% male), and at time 2, 12 months post introduction (n=1572, 69% male). PRIMARY OUTCOMES: At each time, we examined smokers' responses to warnings on packs (negative affect, thinking about warning messages and cognitive elaboration), attitudes toward smoking (perceived likelihood and severity of harm, self-efficacy, response efficacy and quit intentions), knowledge of the health risks of smoking and responses to the new warnings (negative affect, believability, thinking about the harms, reactance and perceived message effectiveness). RESULTS: Awareness of the warnings was low, with only 59% of smokers reporting having seen them at time 2. Between times, we observed a reduction in negative affect toward current warnings (p<0.001), reduced thinking about (p<0.001) and cognitive elaboration of the warning message (p<0.001), and an increase in perceived severity of warnings (p<0.001). When asked about the six new health warnings, we found a reduction in negative affect (p<0.07), cognitions related to harm (p<0.01), believability (p<0.03), reactance (p<0.01) and perceived message effectiveness (p<0.02) between times. CONCLUSIONS: Our data indicate that effectiveness was low prior to the introduction of the new health warnings and at 12 months post introduction. Tobacco control policy should seek to improve exposure to and noticeability of tobacco health warnings in Colombia.

Renal Function in Patients Hospitalized With Anorexia Nervosa Undergoing Refeeding: Findings From the Study of Refeeding to Optimize Inpatient Gains.

PURPOSE: Among complications of malnutrition secondary to anorexia nervosa (AN) or atypical anorexia nervosa (AAN), renal impairment remains poorly elucidated. Evaluating renal function in hospitalized pediatric patients with AN and AAN undergoing refeeding will yield important information to guide clinicians in screening and managing renal dysfunction in this population. METHODS: This is a secondary analysis of data from the Study of Refeeding to Optimize Inpatient Gains trial, a multicenter randomized clinical trial comparing higher calorie refeeding versus lower calorie refeeding in 120 adolescents and young adults hospitalized with medical instability secondary to AN or AAN. Baseline disease characteristics were obtained. Vital sign measurements, weight, electrolytes, and fluid status were evaluated daily to ascertain medical stability. Renal function on admission and throughout hospitalization was quantified using daily creatinine measurement and calculation of the estimated glomerular filtration rate (eGFR) using the modified Schwartz equation. Regression analysis and mixed linear models were utilized to evaluate factors associated with eGFR. RESULTS: Of the 111 participants who completed treatment protocol, 33% had a baseline eGFR less than 90, suggesting renal impairment. Patients who experienced more rapid weight loss and more severe bradycardia were more likely to have low admission eGFR. While eGFR improved during refeeding, eGFR change by day based on refeeding treatment assignment did not reach statistical significance (95% confidence interval, -1.61, 0.15]; p = .095). DISCUSSION: Renal impairment is evident on admission in a significant number of adolescents and young adults hospitalized with AN and AAN. We demonstrate that short-term medical refeeding yields improvement in renal function.

Sexual morph specialisation in a trioecious nematode balances opposing selective forces.

The coexistence of different mating strategies, whereby a species can reproduce both by selfing and outcrossing, is an evolutionary enigma. Theory predicts two predominant stable mating states: outcrossing with strong inbreeding depression or selfing with weak inbreeding depression. As these two mating strategies are subject to opposing selective forces, mixed breeding systems are thought to be a rare transitory state yet can persist even after multiple speciation events. We hypothesise that if each mating strategy plays a distinctive role during some part of the species life history, opposing selective pressures could be balanced, permitting the stable co-existence of selfing and outcrossing sexual morphs. In this scenario, we would expect each morph to be specialised in their respective roles. Here we show, using behavioural, physiological and gene expression studies, that the selfing (hermaphrodite) and outcrossing (female) sexual morphs of the trioecious nematode Auanema freiburgensis have distinct adaptations optimised for their different roles during the life cycle. A. freiburgensis hermaphrodites are known to be produced under stressful conditions and are specialised for dispersal to new habitat patches. Here we show that they exhibit metabolic and intestinal changes enabling them to meet the cost of dispersal and reproduction. In contrast, A. freiburgensis females are produced in favourable conditions and facilitate rapid population growth. We found that females compensate for the lack of reproductive assurance by reallocating resources from intestinal development to mate-finding behaviour. The specialisation of each mating system for its role in the life cycle could balance opposing selective forces allowing the stable maintenance of both mating systems in A. freiburgensis.

Young Adult Anxiety or Depressive Symptoms and Mental Health Service Utilization During the COVID-19 Pandemic.

PURPOSE: Young adult anxiety/depression (mental health) symptoms have increased from prior to the COVID-19 pandemic. This study assessed young adult (aged 18-25 years) anxiety/depressive symptoms, mental health care utilization (prescription drug use, counseling, and/or either), and unmet counseling/therapy needs utilizing the national Household Pulse Survey data from June to July 2021. METHODS: Young adult (n = 2,809) rates and subgroup differences in mental health symptoms (Generalized Anxiety Disorder-2 and/or Patient Health Questionnaire-2) were assessed, as were mental health care utilization and unmet counseling/therapy needs. RESULTS: In total, 48% of young adults had mental health symptoms. Among those, 39% received treatment and 36% reported unmet mental health counseling/therapy needs. DISCUSSION: These findings highlight young adults' ongoing mental health needs and low services receipt. Interventions and further research to reduce barriers to seeking and utilizing mental health care and to increase the capacity of providers to deliver culturally appropriate mental health care are needed.

Investigating the prevalence of anxiety and depression during the first COVID-19 lockdown in the United Kingdom: Systematic review and meta-analyses.

BACKGROUND: The COVID-19 pandemic has had a significant impact on mental health. Specifically, the stringent lockdown restrictions have heightened anxiety and depression. Therefore, monitoring and supporting the mental health of the population during these unprecedented times is an immediate priority. METHODS: In this systematic review and meta-analyses, articles that explored the prevalence of anxiety and depression during the first COVID-19 lockdown in the United Kingdom were included. We searched the databases Embase, Medline (PubMed), Web of Science, and PsycINFO for cross-sectional studies. We conducted meta-analyses of prevalence rates using a random-effects model, and the heterogeneity of studies was examined using the I2 index. RESULTS: Fourteen studies involving 46,158 participants were included in the review. The studies use clinical cut-off scores on anxiety and depression measures to define cases. While the prevalence of anxiety was 31.00% (95% CI = 26.00 to 35.00), the prevalence of depression was 32.00% (95% CI = 29.00 to 35.00). The prevalence of anxiety pre-pandemic was 4.65%, indicating a 26.35% increase. Whereas the prevalence of depression pre-pandemic was 4.12%, indicating a 27.88% increase. Moreover, participants experienced a slightly greater prevalence of depression than anxiety by 1.00%. CONCLUSIONS: To conclude, the first COVID-19 lockdown in the United Kingdom increased the prevalence of anxiety and depression among the general population, compared to pre-pandemic data. Hence, it is vital that policymakers and mental health services maximize their efforts to monitor mental health and provide interventions to support those in need. PRACTITIONER POINTS: Clinical implications Awareness of the high prevalence of anxiety and depression during the first lockdown in the United Kingdom can inform policy development that substantial effort, time, and funding of mental health services are required to support those in need. Similarly, awareness of the prevalence of anxiety and depression in the United Kingdom can contribute to the development of nation-specific interventions and initiatives. Limitations The current review focuses on the UK general population which does not allow the findings to be generalized to the global population. The indirect comparison of the current prevalence rates with the corresponding pre-pandemic prevalence rates obtained from a different study sample increases individual differences, weakening the reliability of the findings.

Adolescent Technology-use Rules and Sleep in a Large Representative Sample.

PURPOSE: This study investigated the prevalence of technology-use rules, typical sleep habits, and associations between rules and sleep using the representative 2017-2018 California Health Interview Survey adolescent sample. METHODS: Adolescents aged 12-17 years completed the California Health Interview Survey, including queries of (1) rules at home regarding times to turn off or put away electronics and (2) school-night bedtime and rise time. Rates of rules and associations between rules and sleep were investigated using descriptive statistics and bivariate and multivariable analyses. RESULTS: Seventy-two percent reported technology-use rules. Rates were comparable across subgroups. Rules and sleep were not significantly associated after adjusting for covariates. Reported time in bed fell below National Sleep Foundation guidelines for 38% of participants. CONCLUSIONS: Most adolescents reported technology-use rules at home. Associations between rules and bedtime were mixed, suggesting that further exploration of contextual and developmental factors is needed. Many reported inadequate sleep duration, supporting sleep as a key topic in adolescent health.

Adapting Drug and Alcohol Therapies for Autistic Adults.

Background: Autistic people may be at a higher risk of drug and alcohol misuse than the general population. Autistic people, however, are under-represented within drug and alcohol support services. This is the first survey of drug and alcohol therapists' perceptions of current service provision for autistic clients and recommendations for reasonable adjustments that therapists can make to enhance successful outcomes. Methods: We conducted an online survey of 122 drug and alcohol therapists, exploring therapists' demographics, training and experience with autistic clients, approaches and adaptations used with autistic clients, and therapists' confidence with autistic clients. Within two focus groups, 11 members of the autistic and broader autism (e.g., family members, professionals) communities reflected on the reasonable adjustments reported by therapists. Results: Most therapists had autistic clients and most therapists had received no autism-specific training. Alcohol misuse was the most common presenting issue, and most therapists reported that treatment outcomes were less favorable for autistic clients than for other groups. Therapists perceived that barriers to successful outcomes were (1) a lack of autism-specific training, (2) a need to adapt therapy for autistic clients, and (3) a lack of shared perspective between the therapist and the autistic client. Previous research has identified a range of reasonable adaptations and, when asked, therapists were moderately confident in their ability to deliver these. Members of the autistic and broader autism communities coproduced guidance detailing how therapists can best adapt their practice for autistic clients including how to structure sessions and the language to use within sessions. Conclusion: This study highlights a need for practical and theoretical training for drug and alcohol therapists to support successful adaptation to current service provision for autistic clients and to develop a shared perspective on the desired aims and outcomes of the therapeutic process.

Why was this study done?: Autistic adults may be at greater risk for consuming drugs and alcohol to harmful levels compared with nonautistic adults. Autistic adults seeking support for drug and alcohol use report that treatment programs for reducing drug and alcohol use do not meet their needs. What was the purpose of this study?: This study aimed to look at the skills, experience, and confidence of drug and alcohol therapists in working with autistic adults and what adaptions they are making to support autistic service users. What did the researchers do?: Through an online questionnaire, the researchers asked 122 drug and alcohol therapists about their experiences with autistic clients (such as what issues they presented with), their autism training, and any perceived barriers or adaptations made to their service. Researchers also asked the therapists how confident they were to work with autistic clients and how successful their treatment was when compared with other client groups. Through two focus groups, the researchers then asked members of the autistic and broader autism (e.g., family members, professionals) communities to reflect how the reasonable adaptions reported by the therapist could be most effective for the autistic community. What were the results of the study?: Most therapists had autistic clients and most therapists had received no autism-specific training. Alcohol was the most reported misused substance that therapists working with autistic adults encountered. Most therapists also reported that treatment outcomes were less favorable for autistic clients than for other groups. Therapists identified lack of training as a barrier to providing support for autistic adults. Therapists suggested that a one-size-fits-all approach was not helpful for this group and most were moderately confident that they would be able to deliver adapted therapy to autistic clients. Members of the autistic and broader autism communities developed guidance for therapists to implement effective adaptations for autistic clients. What do these findings add to what was already known?: This was the first survey of drug and alcohol therapists regarding their service provision for autistic clients. The findings highlight the need for therapists to be trained in how to adapt support and treatment to meet the individual needs of autistic clients. What are potential weaknesses in the study?: One limitation of this study is the convenience sample. This may limit how we can generalize the findings. By asking specifically about autistic clients, we may have biased responses from therapists who have worked with autistic adults. How will these findings help autistic adults now or in the future?: The findings from this study highlight that treatment programs for drug and alcohol misuse do not consider the needs of autistic adults. However, they also suggest that various approaches and adaptions can be made to support autistic clients. In addition to supporting adaptions made by therapists, the guidance developed could be a useful framework for autistic clients to discuss their session-support needs with therapists. Future research should look at the effectiveness of these adaptions in improving treatment outcomes for autistic clients.

De Novo Genome Assembly of Auanema Melissensis, a Trioecious Free-Living Nematode.

Nematodes of the genus Auanema are interesting models for studying sex determination mechanisms because their populations consist of three sexual morphs (males, females, and hermaphrodites) and produce skewed sex ratios. Here, we introduce a new undescribed species of this genus, Auanema melissensis n. sp., together with its draft nuclear genome. This species is also trioecious and does not cross with the other described species A. rhodensis or A. freiburgensis. Similar to A. freiburgensis, A. melissensis' maternal environment influences the hermaphrodite versus female sex determination of the offspring. The genome of A. melissensis is ~60 Mb, containing 11,040 protein-coding genes and 8.07% of repeat sequences. Using the estimated ancestral chromosomal gene content (Nigon elements), it was possible to identify putative X chromosome scaffolds.
