We present the first detailed analysis of H3+ nightside emission from Jupiter, using Visual and Infrared Mapping Spectrometer (VIMS) data from the Cassini flyby in 2000–2001, producing the first ...Jovian maps of nightside H3+ emission, temperature, and column density. Using these, we identify and characterize regions of H3+ nightside emission, compared against past observations of H3+ emission on the dayside. We focus our investigation on the region previously described as “mid‐to‐low latitude emission,” the source for which has been controversial. We find that the brightest of this emission is generated at Jovigraphic latitudes similar to the most equatorward extent of the main auroral emission but concentrated at longitudes eastward of this emission. The emission is produced by enhanced H3+ density, with temperatures dropping away in this region. This emission has a loose association with the predicted location of diffuse aurora produced by pitch angle scattering in the north, but not in the south. This emission also lays in the path of subrotating winds flowing from the aurora, suggesting a transport origin. Some differences are seen between dayside and nightside subauroral emissions, with dayside emission extending more equatorward, perhaps caused by the lack of sunlight ionization on the nightside, and unmeasured changes in temperature. Ionospheric temperatures are hotter in the polar region (~1100–1500 K), dropping away toward the equator (as low as 750 K), broadly similar to values on the dayside, highlighting the dominance of auroral effects in the polar region. No equatorial emission is observed, suggesting that very little particle precipitation occurs away from the polar regions.
Key Points
Jupiter's nightside auroral ionosphere is similar to the dayside
Sub‐auroral emission is concentrated close to the aurora, at eastward longitudes T
This emission is best explained by sub‐rotating winds flowing from the aurora
Objective: To review the literature on the experiences of boys and men exposed to childhood sexual abuse, and to assess the implications of this literature for trials of interventions and tailored ...services for this population. Method: We conducted a narrative review of papers pertaining to boys and men exposed to childhood sexual abuse. Implications of this literature for treatment were critically appraised. Results: Boys and men suffer the negative sequelae of childhood sexual abuse to the same (and sometimes greater) extent as girls and women. Boys and men also experience a number of unique challenges, as the abuse experience may undermine masculine identities and relations. This conflict may contribute to the underreporting of childhood sexual abuse among boys and men. Boys and men are less likely to disclose their abuse experience and wait longer to disclose compared to girls and women. Existing estimates therefore likely underestimate the prevalence of childhood sexual abuse among boys and men. Additionally, to date, intervention trials for individuals exposed to childhood sexual abuse have included a disproportionately low number of boys and men, even based on existing prevalence estimates. Conclusions: Further investigation into the treatment needs of boys and men exposed to childhood sexual abuse is critically important. To facilitate a better understanding of their needs, intervention studies for this cohort should include a greater proportion of boys and men. Studies should also assess the influence of boys' and men's alignments to masculine norms for moderating treatment outcomes as a means to guide gender-sensitive treatments.
Clinical Impact Statement
This narrative review found that reported rates of boys and men exposed to childhood sexual abuse may be underestimated. Additionally, boys and men are underrepresented in studies evaluating psychological treatments for survivors of childhood sexual abuse. Taken together, these findings indicate a pressing need for studies to actively seek out and include a greater proportion of boys and men.

We estimate parameters of a general isolation-with-migration model using resequence data from mitochondrial DNA (mtDNA), the Y chromosome, and two loci on the X chromosome in samples of 25-50 ...individuals from each of 10 human populations. Application of a coalescent-based Markov chain Monte Carlo technique allows simultaneous inference of divergence times, rates of gene flow, as well as changes in effective population size. Results from comparisons between sub-Saharan African and Eurasian populations estimate that 1500 individuals founded the ancestral Eurasian population approximately 40 thousand years ago (KYA). Furthermore, these small Eurasian founding populations appear to have grown much more dramatically than either African or Oceanian populations. Analyses of sub-Saharan African populations provide little evidence for a history of population bottlenecks and suggest that they began diverging from one another upward of 50 KYA. We surmise that ancestral African populations had already been geographically structured prior to the founding of ancestral Eurasian populations. African populations are shown to experience low levels of mitochondrial DNA gene flow, but high levels of Y chromosome gene flow. In particular, Y chromosome gene flow appears to be asymmetric, i.e., from the Bantu-speaking population into other African populations. Conversely, mitochondrial gene flow is more extensive between non-African populations, but appears to be absent between European and Asian populations.
IMPORTANCE: Enhanced Recovery After Surgery (ERAS) guidelines and the World Health Organization Surgical Safety Checklist (SSC) are 2 well-established tools for optimizing patient outcomes ...perioperatively. OBJECTIVE: To integrate the 2 tools to facilitate key perioperative decision-making. EVIDENCE REVIEW: Snowball sampling recruited international ERAS users from multiple clinical specialties. A 3-round modified Delphi consensus model was used to evaluate 27 colorectal or gynecologic oncology ERAS recommendations for appropriateness to include in an ERAS SSC. Items attaining potential consensus (65%-69% agreement) or consensus (≥70% agreement) were used to develop ERAS-specific SSC prompts. These proposed prompts were evaluated in a second round by the panelists with regard to inclusion, modification, or exclusion. A final round of interactive discussion using quantitative consensus and qualitative comments was used to produce an ERAS-specific SSC. The panel of ERAS experts included surgeons, anesthesiologists, and nurses within diverse practice settings from 19 countries. Final analysis was conducted in May 2022. FINDINGS: Round 1 was completed by 105 experts from 18 countries. Eleven ERAS components met criteria for development into an SSC prompt. Round 2 was completed by 88 experts. There was universal consensus (≥70% agreement) to include all 37 proposed prompts within the 3-part ERAS-specific SSC (used prior to induction of anesthesia, skin incision, and leaving the operating theater). A third round of qualitative comment review and expert discussion was used to produce a final ERAS-specific SSC that expands on the current WHO SSC to include discussion of analgesia strategies, nausea prevention, appropriate fasting, fluid management, anesthetic protocols, appropriate skin preparation, deep vein thrombosis prophylaxis, hypothermia prevention, use of foley catheters, and surgical access. The final products of this work included an ERAS-specific SSC ready for implementation and a set of recommendations to integrate ERAS elements into existing SSCs. CONCLUSIONS AND RELEVANCE: The SSC could be modified to align with ERAS recommendations for patients undergoing major surgery within an ERAS protocol. The stakeholder- and expert-generated ERAS SSC could be adopted directly, or the recommendations for modification could be applied to an existing institutional SSC to facilitate implementation.
The long-chain n-3 PUFA, EPA, is believed to be important for skin health, including roles in the modulation of inflammation and protection from photodamage. FFQ and blood levels are used as ...non-invasive proxies for assessing skin PUFA levels, but studies examining how well these proxies reflect target organ content are lacking. In seventy-eight healthy women (mean age 42·8, range 21–60 years) residing in Greater Manchester, we performed a quantitative analysis of long-chain n-3 PUFA nutrition estimated from a self-reported FFQ (n 75) and correlated this with n-3 PUFA concentrations in erythrocytes (n 72) and dermis (n 39). Linear associations between the three n-3 PUFA measurements were assessed by Spearman correlation coefficients and agreement between these measurements was estimated. Average total dietary content of the principal long-chain n-3 PUFA EPA and DHA was 171 (sd 168) and 236 (sd 248) mg/d, respectively. EPA showed significant correlations between FFQ assessments and both erythrocyte (r 0·57, P< 0·0001) and dermal (r 0·33, P= 0·05) levels, as well as between erythrocytes and dermis (r 0·45, P= 0·008). FFQ intake of DHA and the sum of n-3 PUFA also correlated well with erythrocyte concentrations (r 0·50, P< 0·0001; r 0·27, P= 0·03). Agreement between ranked thirds of dietary intake, blood and dermis approached 50 % for EPA and DHA, though gross misclassification was lower for EPA. Thus, FFQ estimates and circulating levels of the dietary long-chain n-3 PUFA, EPA, may be utilised as well-correlated measures of its dermal bioavailability.
A 2.4-kb stretch within the RRM2P4 region of the X chromosome, previously sequenced in a sample of 41 globally distributed humans, displayed both an ancient time to the most recent common ancestor ...(e.g., a TMRCA of approximately 2 million years) and a basal clade composed entirely of Asian sequences. This pattern was interpreted to reflect a history of introgressive hybridization from archaic hominins (most likely Asian Homo erectus) into the anatomically modern human genome. Here, we address this hypothesis by resequencing the 2.4-kb RRM2P4 region in 131 African and 122 non-African individuals and by extending the length of sequence in a window of 16.5 kb encompassing the RRM2P4 pseudogene in a subset of 90 individuals. We find that both the ancient TMRCA and the skew in non-African representation in one of the basal clades are essentially limited to the central 2.4-kb region. We define a new summary statistic called the minimum clade proportion (pmc), which quantifies the proportion of individuals from a specified geographic region in each of the two basal clades of a binary gene tree, and then employ coalescent simulations to assess the likelihood of the observed central RRM2P4 genealogy under two alternative views of human evolutionary history: recent African replacement (RAR) and archaic admixture (AA). A molecular-clock-based TMRCA estimate of 2.33 million years is a statistical outlier under the RAR model; however, the large variance associated with this estimate makes it difficult to distinguish the predictions of the human origins models tested here. The pmc summary statistic, which has improved power with larger samples of chromosomes, yields values that are significantly unlikely under the RAR model and fit expectations better under a range of archaic admixture scenarios.

Abstract
The objective of this guideline is to provide up-to-date, evidence-based recommendations for the management of SLE that builds upon the existing treatment guideline for adults living with ...SLE published in 2017. This will incorporate advances in the assessment, diagnosis, monitoring, non-pharmacological and pharmacological management of SLE. General approaches to management as well as organ-specific treatment, including lupus nephritis and cutaneous lupus, will be covered. This will be the first guideline in SLE using a whole life course approach from childhood through adolescence and adulthood. The guideline will be developed with people with SLE as an important target audience in addition to healthcare professionals. It will include guidance related to emerging approved therapies and account for National Institute for Health and Care Excellence Technology Appraisals, National Health Service England clinical commissioning policies and national guidance relevant to SLE. The guideline will be developed using the methods and rigorous processes outlined in ‘Creating Clinical Guidelines: Our Protocol’ by the British Society for Rheumatology.
Lay Summary
Systemic lupus erythematosus (SLE) is a lifelong condition in which the immune system damages the body’s own tissues, causing various symptoms including rashes, hair loss, mouth ulcers, joint pain and overwhelming tiredness. It can also affect major organs including the kidneys, heart, lungs and brain. SLE can present during childhood, but most commonly affects young and middle-aged females. It is approximately nine times more common in females than males. The disease can lead to disability, poor quality of life and even death in severe cases. Treatments can often be difficult to tolerate and can cause both short- and long-term side effects. Guidelines developed by the British Society for Rheumatology aim to provide guidance for diagnosing and treating people with SLE. This is necessary to ensure that the most up-to-date approach is followed, utilising the safest and most effective treatments. This article describes the plan for a guideline in SLE that is being updated to cover new evidence that has been published since 2017 relating to the treatment and management of SLE. The guideline will take a whole life course approach, from childhood to adulthood, and is being undertaken by a working group consisting of paediatric and adult rheumatologists and nephrologists, SLE experts, general practitioners, specialist nurses and other healthcare professionals, together with people with SLE and representatives from patient organizations. The guideline will be developed using the methods and processes outlined in the British Society for Rheumatology document ‘Creating Clinical Guidelines: Our Protocol’.
