SO2, silicate clouds, but no CH4 detected in a warm Neptune.

WASP-107b is a warm (approximately 740 K) transiting planet with a Neptune-like mass of roughly 30.5 M⊕ and Jupiter-like radius of about 0.94 RJ (refs. 1,2), whose extended atmosphere is eroding3. Previous observations showed evidence for water vapour and a thick, high-altitude condensate layer in the atmosphere of WASP-107b (refs. 4,5). Recently, photochemically produced sulfur dioxide (SO2) was detected in the atmosphere of a hot (about 1,200 K) Saturn-mass planet from transmission spectroscopy near 4.05 µm (refs. 6,7), but for temperatures below about 1,000 K, sulfur is predicted to preferably form sulfur allotropes instead of SO2 (refs. 8-10). Here we report the 9σ detection of two fundamental vibration bands of SO2, at 7.35 µm and 8.69 µm, in the transmission spectrum of WASP-107b using the Mid-Infrared Instrument (MIRI) of JWST. This discovery establishes WASP-107b as the second irradiated exoplanet with confirmed photochemistry, extending the temperature range of exoplanets exhibiting detected photochemistry from about 1,200 K down to about 740 K. Furthermore, our spectral analysis reveals the presence of silicate clouds, which are strongly favoured (around 7σ) over simpler cloud set-ups. Furthermore, water is detected (around 12σ) but methane is not. These findings provide evidence of disequilibrium chemistry and indicate a dynamically active atmosphere with a super-solar metallicity.

15NH3 in the atmosphere of a cool brown dwarf.

Brown dwarfs serve as ideal laboratories for studying the atmospheres of giant exoplanets on wide orbits, as the governing physical and chemical processes within them are nearly identical1,2. Understanding the formation of gas-giant planets is challenging, often involving the endeavour to link atmospheric abundance ratios, such as the carbon-to-oxygen (C/O) ratio, to formation scenarios3. However, the complexity of planet formation requires further tracers, as the unambiguous interpretation of the measured C/O ratio is fraught with complexity4. Isotope ratios, such as deuterium to hydrogen and 14N/15N, offer a promising avenue to gain further insight into this formation process, mirroring their use within the Solar System5-7. For exoplanets, only a handful of constraints on 12C/13C exist, pointing to the accretion of 13C-rich ice from beyond the CO iceline of the disks8,9. Here we report on the mid-infrared detection of the 14NH3 and 15NH3 isotopologues in the atmosphere of a cool brown dwarf with an effective temperature of 380 K in a spectrum taken with the Mid-Infrared Instrument (MIRI) of JWST. As expected, our results reveal a 14N/15N value consistent with star-like formation by gravitational collapse, demonstrating that this ratio can be accurately constrained. Because young stars and their planets should be more strongly enriched in the 15N isotope10, we expect that 15NH3 will be detectable in several cold, wide-separation exoplanets.

The Craniofacial Collaboration UK: Developmental Outcomes in 7- and 10-Year-Old Children With Metopic Synostosis.

The Craniofacial Collaboration (CC-UK) is a shared initiative across the Psychology teams attached to 4 highly specialized craniofacial centers in the United Kingdom. The CC-UK aims to address key limitations in the existing craniofacial literature by analyzing data for homogenous samples of children with craniosynostosis. This article presents the fifth wave of CC-UK data collection, focused on 7- and 10-year olds who have undergone primary corrective surgery for metopic synostosis (MS). Data for children with sagittal synostosis and MS have previously been presented at 3 and 5 years. This paper continues to build on this with consideration to older age groups, presenting the first CC-UK analysis of cognitive assessment data using the Wechsler Abbreviated Scale of Intelligence-Second Edition. Results show that the majority of children with MS fall within the average ranges across behavioral and neurodevelopmental domains. However, several domains indicated a trend of heightened concern when compared with normative data, particularly for parent-reported outcomes, suggesting that there may be some subtle difficulties for children with MS. Consideration of how these findings compare with that of previous CC-UK analyses is explored. Further, implications for clinical practice and future research are considered, with the need for longitudinal analyses, as well as data from multiple perspectives (eg, school, parents, and self) at older age points to establish patterns over time. Through collaboration across the highly specialized craniofacial centers, the CC-UK hopes to work toward this goal moving forward.

The chemical inventory of the inner regions of planet-forming disks - the JWST/MINDS program.

The understanding of planet formation has changed recently, embracing the new idea of pebble accretion. This means that the influx of pebbles from the outer regions of planet-forming disks to their inner zones could determine the composition of planets and their atmospheres. The solid and molecular components delivered to the planet-forming region can be best characterized by mid-infrared spectroscopy. With Spitzer low-resolution (R = 100, 600) spectroscopy, this approach was limited to the detection of abundant molecules, such as H2O, C2H2, HCN and CO2. This contribution will present the first results of the MINDS (MIRI mid-INfrared Disk Survey, PI:Th Henning) project. Due do the sensitivity and spectral resolution provided by the James Webb Space Telescope (JWST), we now have a unique tool to obtain the full inventory of chemistry in the inner disks of solar-type stars and brown dwarfs, including also less-abundant hydrocarbons and isotopologues. The Integral Field Unit (IFU) capabilities will enable at the same time spatial studies of the continuum and line emission in extended sources such as debris disks, the flying saucer and also the search for mid-IR signatures of forming planets in systems such as PDS 70. These JWST observations are complementary to ALMA and NOEMA observations of outer-disk chemistry; together these datasets will provide an integral view of the processes occurring during the planet-formation phase.

Delivery Outcomes and Postpartum Readmissions Associated with Ehlers-Danlos Syndrome.

OBJECTIVE: Given that updated estimates of Ehlers-Danlos syndrome and risks for obstetric complications including postpartum readmission may be of public health significance, we sought to analyze associated obstetric trends and outcomes in a nationally representative population. STUDY DESIGN: The 2016 to 2020 Nationwide Readmissions Database was used for this retrospective cohort study. Delivery hospitalizations to women aged 15 to 54 with and without Ehlers-Danlos syndrome were identified. Temporal trends in Ehlers-Danlos syndrome diagnoses during delivery hospitalizations were analyzed using joinpoint regression to estimate the average annual percent change with 95% confidence intervals (CIs). To determine whether adverse obstetric outcomes during the delivery were associated with Ehlers-Danlos syndrome, unadjusted and adjusted logistic regression models were fit with unadjusted (odds ratio [OR]) and adjusted ORs with 95% CIs as measures of association. In addition to analyzing adverse delivery outcomes, risk for 60-day postpartum readmission was analyzed. RESULTS: An estimated 18,214,542 delivery hospitalizations were included of which 7,378 (4.1 per 10,000) had an associated diagnosis of Ehlers-Danlos syndrome. Ehlers-Danlos syndrome diagnosis increased from 2.7 to 5.2 per 10,000 delivery hospitalization from 2016 to 2020 (average annual percent change increase of 16.1%, 95% CI: 9.4%, 23.1%). Ehlers-Danlos syndrome was associated with increased odds of nontransfusion severe maternal morbidity (OR: 1.84, 95% CI: 1.38, 2.45), cervical insufficiency (OR: 2.14, 95% CI: 1.46, 3.13), postpartum hemorrhage (OR: 1.41, 95% CI: 1.17, 1.68), cesarean delivery (OR: 1.26, 95% CI: 1.17, 1.36), and preterm delivery (OR: 1.35, 95% CI: 1.16, 1.56). Estimates for transfusion, placental abruption, and placenta previa did not differ significantly. Risk for 60-day postpartum readmission was 3.0% among deliveries with Ehlers-Danlos (OR: 1.76, 95% CI: 1.37, 2.25). CONCLUSION: Ehlers-Danlos syndrome diagnoses approximately doubled over the 5-year study period and was associated with a range of adverse obstetric outcomes and complications during delivery hospitalizations as well as risk for postpartum readmission. KEY POINTS: · Ehlers-Danlos syndrome diagnoses approximately doubled over the 5-year study period.. · Ehlers-Danlos was associated with a range of adverse obstetric outcomes.. · Ehlers-Danlos was associated with increased readmission risk..

The Craniofacial Collaboration UK: Developmental Outcomes in 5-Year-Old Children With Metopic Synostosis.

The Craniofacial Collaboration (CC-UK) was setup in 2015 as a joint initiative between the Psychology teams attached to the 4 highly specialized craniofacial centers in the United Kingdom. The CC-UK aims to address key limitations in the existing craniofacial literature by applying strict exclusion criteria and collating clinical data on a homogenous sample of children. This article reports the fourth wave of data collection from the CC-UK, with the analysis of developmental and behavioral outcomes for children with metopic synostosis at 5 years old. Previous data for sagittal synostosis at 3 and 5 years, and metopic synostosis at 3 years, have been presented. This paper offers the first analysis of developmental and behavioral parent-report measures at school age for metopic synostosis. All children in the current data set had primary corrective surgery. Findings highlight similar patterns to that of previous research among children with single-suture craniosynostosis, as well as earlier CC-UK analyses, with the majority falling within 1 standard deviation of the normative mean. However, differences across key behavioral and emotional domains, with some areas reporting heightened concerns compared with those detected among sagittal groups, may suggest that subtle differences between individual diagnostic groups are present. This further highlights the importance of utilizing homogenous samples within the field of craniofacial research. To further build upon this work, and to provide a greater understanding of how these difficulties and concerns may develop, or diminish, over time, further consideration to longitudinal outcomes is needed for individual diagnostic groups. Through this collaboration, the authors seek to achieve this goal in their future work.

Lessons in "Slow" Engagement From Staff and Administrators at a Prebooking Jail Diversion Program.

Objective: In this study, the authors elicited the perspectives of criminal justice and mental health stakeholders about a prebooking jail diversion program, the Judge Ed Emmett Mental Health Diversion Center, serving primarily individuals experiencing chronic homelessness and diagnosed as having a serious mental illness. Methods: The authors analyzed semistructured interviews with 19 participants and observational fieldnotes from 60 hours of ethnographic fieldwork, conducted from January to July 2020 and including five administrative-level meetings. They used qualitative coding to develop themes. Administrative data were also reviewed. Results: Engagement of clients in the program was a major theme. Barriers to engagement included clients' fear of police involvement and strict rules around smoking. Facilitators to engagement included "slow" engagement, or gradual, gentle microengagements over time and across multiple visits, ideally with peer counselors. Conclusions: To promote client use of services at this critical point of care, jail diversion programs might consider ongoing negotiations with clients to balance expectations between the criminal justice and mental health systems of care by using "slow" client engagement, limiting police involvement, and adopting trauma-informed and harm-reduction approaches.

Co-Produced Care in Veterinary Services: A Qualitative Study of UK Stakeholders' Perspectives.

Changes in client behaviour and expectations, and a dynamic business landscape, amplify the already complex nature of veterinary and animal health service provision. Drawing on prior experiences, veterinary clients increasingly pursue enhanced involvement in services and have expectations of relationship-centred care. Co-production as a conceptualisation of reciprocity in service provision is a fundamental offering in the services sector, including human medicine, yet the role of co-production in veterinary services has been minimally explored. Utilising a service satisfaction framework, semi-structured interviews (n = 13) were completed with three veterinary stakeholder groups, veterinarians, allied animal health practitioners, and veterinary clients. Interview transcript data were subject to the qualitative data analysis techniques, thematic analysis and grounded theory, to explore relationship-centred care and subsequently conceptualise co-production service for the sector. Six latent dimensions of service were emergent, defined as: empathy, bespoke care, professional integrity, value for money, confident relationships, and accessibility. The dimensions strongly advocate wider sector adoption of a co-produced service, and a contextualised co-production framework is presented. Pragmatic challenges associated with integration of active veterinary clients in a practitioner-client partnership are evident. However, adopting a people-centric approach to veterinary services and partnerships with clients can confer the advantages of improved client satisfaction, enhanced treatment adherence and outcomes, and business sustainability.

Decision Making About Pathways Through Care for Racially and Ethnically Diverse Young Adults With Early Psychosis.

OBJECTIVE: This study elicited factors that shaped treatment decision making for young adults and their key supporters after an initial hospitalization for psychosis to generate hypotheses about how to improve service engagement. METHODS: This prospective, longitudinal, ethnographic study (using home visits, interviews, and hospital-based fieldwork) asked what mattered to 18 young adults primarily from racial-ethnic minority groups and 19 of their self-identified key supporters (N=37) as they made decisions about treatment during the 12-week critical period after an initial hospitalization for psychosis. The analytical approach used inductive coding and constructivist grounded theory methods to analyze interview transcripts and field notes from home visits and generate hypotheses about key factors that seemed to affect treatment decision making. Factors were ranked in order of frequency across all participants (overall, young adults only, and key supporters only). RESULTS: Among the 37 total participants (young adults and key supporters), more than two-thirds were concerned with getting back to normal, the insufficient mental health care on offer, police involvement in their pathway to care, feeling worse, and needing help with repairing strained relationships. More than one-half were concerned with how young adults would be able to live independently in the future, paying for mental health care, distrusting mental health diagnoses, managing social pressure to use substances, feeling disempowered by hospitalization experiences, and managing transportation challenges. CONCLUSIONS: To better engage young adults with early psychosis in care, including those from racial-ethnic minority groups, there is a need to design services that address the specific concerns of their everyday lives in the context of the initial hospitalization and posthospitalization period.

The KIR2DS2/DL2 genotype is associated with adult persistent/chronic and relapsed immune thrombocytopenia independently of FCGR3a-158 polymorphisms.

Adult immune thrombocytopenia (ITP) is a heterogeneous disease and its immunobiology is incompletely understood. Establishing associations between candidate genes and ITP susceptibility may provide insight into pathogenesis. Previous studies have associated overrepresentation of FCGR3a-V158 allele with pediatric ITP. We prospectively accrued DNA from 102 adult patients with persistent/chronic or relapsed primary ITP identified by defined criteria. The distribution of KIR2 genes and polymorphisms of FCGR3a, both associated with autoimmunity, were compared with 105 healthy white individuals. Results were stratified by ethnicity. Carriers of the KIR2DS2/KIR2DL2 genotype [KIR2DS2/KIR2DL2 versus KIR2DS2/KIR2DL2 and KIR2DS2/KIR2DL2; odds ratio (OR) 2.51, P = 0.002] were overrepresented. In addition, frequency of the high-binding affinity FCGR3a-V/V158 genotype (VV versus VF/FF; OR = 3.05, P = 0.007) was increased, whereas that of the FCGR3a-F158 allele was reduced (OR = 2.58, P = 0.00.002). In a regression model to adjust for age, sex and the effects of the other gene, the KIR2 genotype independently conferred increased susceptibility from the FCGR3a-158 polymorphisms. In a comparison of healthy controls and a tightly defined cohort of adult ITP patients, the KIR2DS2/KIR2DL2 genotype was found to be associated with ITP independently of FCGR3a-158 polymorphisms. Further studies are required to establish the mechanistic basis for these observations and their potential impact on immune-based therapies.
