RESUMEN
BACKGROUND: This paper examined whether distinct life-course trajectories of psychological distress from adolescence to midlife were associated with poorer mental health outcomes during the pandemic. METHODS: We present a secondary analysis of two nationally representative British birth cohorts, the 1958 National Child Development Study (NCDS) and 1970 British Cohort Study (BCS70). We used latent variable mixture models to identify pre-pandemic longitudinal trajectories of psychological distress and a modified Poisson model with robust standard errors to estimate associations with psychological distress, life satisfaction and loneliness at different points during the pandemic. RESULTS: Our analysis identified five distinct pre-pandemic trajectories of psychological distress in both cohorts. All trajectories with prior symptoms of psychological distress irrespective of age of onset, severity and chronicity were associated with a greater relative risk of poorer mental health outcomes during the pandemic and the probability of poorer mental health associated with psychological distress trajectories remained fairly constant. The relationship was not fully attenuated when most recent pre-pandemic psychological distress and other midlife factors were controlled for. CONCLUSIONS: Whilst life-course trajectories with any prior symptoms of psychological distress put individuals at greater risk of poor mental health outcomes during the pandemic, those with chronic and more recent occurrences were at highest risk. In addition, prior poor mental health during the adult life-course may mean individuals are less resilient to shocks, such as pandemics. Our findings show the importance of considering heterogeneous mental health trajectories across the life-course in the general population in addition to population average trends.
RESUMEN
Stress can have long-lasting impacts on plants. Here we report the long-term effects of the stress hormone jasmonic acid (JA) on the defence phenotype, transcriptome and DNA methylome of Arabidopsis. Three weeks after transient JA signalling, 5-week-old plants retained induced resistance (IR) against herbivory but showed increased susceptibility to pathogens. Transcriptome analysis revealed long-term priming and/or upregulation of JA-dependent defence genes but repression of ethylene- and salicylic acid-dependent genes. Long-term JA-IR was associated with shifts in glucosinolate composition and required MYC2/3/4 transcription factors, RNA-directed DNA methylation, the DNA demethylase ROS1 and the small RNA (sRNA)-binding protein AGO1. Although methylome analysis did not reveal consistent changes in DNA methylation near MYC2/3/4-controlled genes, JA-treated plants were specifically enriched with hypomethylated ATREP2 transposable elements (TEs). Epigenomic characterization of mutants and transgenic lines revealed that ATREP2 TEs are regulated by RdDM and ROS1 and produce 21 nt sRNAs that bind to nuclear AGO1. Since ATREP2 TEs are enriched with sequences from IR-related defence genes, our results suggest that AGO1-associated sRNAs from hypomethylated ATREP2 TEs trans-regulate long-lasting memory of JA-dependent immunity.

BACKGROUND: To assess the feasibility and acceptability of conducting a trial of the clinical effectiveness and cost-effectiveness of a new case-management intervention to facilitate the return to work of health care workers, on sick leave, having a common mental disorder (CMD). METHODS: A mixed methods feasibility study. RESULTS: Systematic review examined 40 articles and 2 guidelines. Forty-nine National Health Service Occupational Health (OH) providers completed a usual care survey. We trained six OH nurses as case managers and established six recruitment sites. Forty-two out of 1938 staff on sick leave with a CMD were screened for eligibility, and 24 participants were recruited. Out of them, 94% were female. Eleven participants received the intervention and 13 received usual care. Engagement with most intervention components was excellent. Return-to-work self-efficacy improved more in the intervention group than in the usual care group. Qualitative feedback showed the intervention was acceptable. CONCLUSIONS: The intervention was acceptable, feasible and low cost to deliver, but it was not considered feasible to recommend a large-scale effectiveness trial unless an effective method could be devised to improve the early OH referral of staff sick with CMD. Alternatively, the intervention could be trialled as a new stand-alone OH intervention initiated at the time of usual OH referral.

Many Ghanaians identify their country's most enduring female initiation rite as a risk factor for early sexual debut, claiming that initiates interpret the rite as a normative starting point for sexual activity as was standard in the past. However, the assumption that African initiation rites may hasten sexual debut has not been statistically substantiated. This study explores this association using three waves of longitudinal data collected between 2010 to 2013 from 690 girls and young women aged 12-19, about half of whom had participated in the rite. The results suggest that initiates typically participate in the rite at age 11 and begin having sex around age 16, about six months earlier than non-initiates. Results from survival analyses correspondingly indicate that initiates are 50% more likely to report sexual debut than their non-initiated counterparts. This relationship remains robust when accounting for confounding variables and reverse causality and is not moderated by socioeconomic status. Findings suggest that initiation rites should be understood as having potentially meaningful implications for adolescent sexual debut and sexual and reproductive health outcomes in sub-Saharan Africa. Capitalising on initiation rites for their role in sexual socialisation may be a valuable opportunity to promote sexual and reproductive health among youth.

OBJECTIVE: This study aimed to investigate the use of the head and neck cancer risk calculator version 2 in a primary care setting and to evaluate the impact of the risk calculator on the number of referrals stratified by urgency and cancer yield. METHOD: Referrals between April 2019 and August 2019, April 2020 and July 2020 (pre-risk calculator) and August 2020 and July 2021 (post-risk calculator) were analysed. Referral urgency, head and neck cancer risk calculator version 2 score, cancer diagnosis, cancer type and further investigations were recorded. RESULTS: The 2023 patient encounters were analysed; there were 1110 (55 per cent) referrals before head and neck cancer risk calculator version 2 use and 913 (45 per cent) after head and neck cancer risk calculator version 2 use. A higher proportion of older (p < 0.001) and male (p < 0.013) patients were seen post-head and neck cancer risk calculator version 2 use. All cancer cases were seen on the urgent suspicion of cancer pathway post-head and neck cancer risk calculator version 2 use; however, a higher proportion of patients were seen as urgent suspicion of cancer (51.1 vs 83.5 per cent; p < 0.001). Overall, the cancer diagnosis rate increased from 2.7 to 4.1 per cent. CONCLUSION: The head and neck cancer risk calculator version 2 had high sensitivity in cancer diagnosis. More studies are required to optimise the predicted versus actual cancer probability gap.

INTRODUCTION: The thermoneutral zone (TNZ) defines the range of ambient temperatures at which resting metabolic rate is at a minimum without sensible dry heat loss; the body not needing to defend its core temperature. The TNZ has been defined in a number of species yet surprisingly, in humans only its lower limit has been well characterised; indeed, it is not yet clear if there is an upper limit at which metabolic rate increases. AIM: To evaluate the evidence for a metabolic upper critical temperature to the thermoneutral zone in humans. METHODS: We synthesised current evidence about an upper limit to the human TNZ, highlighting the contradictions in the literature, and then discussed likely explanations for those contradictions. RESULTS: The data from relevant studies differ in terms of whether they indicate that the TNZ has an upper limit, and this was related to the fundamental type of heat exposure protocol employed. Those studies showing evidence for an upper limit associated that limit with a wide range of temperatures. CONCLUSIONS: We offer suggestions for future studies that should clarify the presence/absence of an upper limit to the TNZ and if present, where it lies.

The need for a workforce able to address the health care needs of older adults has been well established. Individuals with kidney disease experience an extensive number of transitions of care across health care settings related to the kidney disease process and the number of health care providers involved in their care. Kidney disease is multifactorial, and the prevention of progression of disease and poor outcomes are key to improving the health of individuals with kidney disease. Nurses and nurse practitioners can improve the outcomes for individuals with complex comorbid conditions and kidney disease especially during the transitions of care.

RATIONALE AND OBJECTIVES: Virtual residency interviews have become crucial in maintaining CDC-recommended precautionary measures throughout the ongoing COVID-era. However, scant literature exists regarding the direct impact the pandemic has had on the radiology program selection process, including preferred modalities of residency interviews and social media utilization. This survey aimed to understand how radiology programs adapted to changes in the 2020-2021 virtual application cycle. MATERIALS AND METHODS: A 32-question survey was distributed to 194 residency programs between July and August of 2021. Data were analyzed primarily by using descriptive statistics and Paired Student's T-testing. RESULTS: A total of 31 programs completed the survey, yielding a response rate of 16%. When queried about the perceived success of virtual interviews during the 2020-2021 application cycle, 21 programs (68%) said the new interview format was very successful. Twenty-seven of the programs (87%) believed they were able to adequately gauge applicants through virtual interviews. However, when surveyed about personal preferences for interviews, the responses were more evenly distributed between virtual (11/31, 35%) and in-person (14/31, 45%). Pre-COVID, the top three criteria programs used to rank candidates were USMLE Step 1 score (20/31, 65%), letters of recommendation (17/31, 55%), and MSPE (12/31, 39%). Within the virtual, COVID-19 era, these criteria remained statistically unchanged (p = 0.22): USMLE Step 1 score (21/31, 68%), letters of recommendation (17/31, 55%), and MSPE (14/31, 45%). About half of programs who had not previously utilized social media (12 of 23, 52%) created accounts, mostly via Twitter or Instagram. CONCLUSION: The primary findings indicate that programs perceived success with virtually interviewing and ranking applicants, the criteria to rank applicants remain unchanged despite the virtual environment, and programs' social media utilization increased.

Dropout events are dramatic decreases in radiation belt electron populations that can occur in as little as 30 minutes. Loss to magnetopause due to a combination of magnetopause shadowing and outward radial transport plays a significant role in these events. We examine the dropout of relativistic electron populations during the October 2012 geomagnetic storm using simulated electron phase space density, evaluating the contribution of different processes to losses across the magnetopause. We compare loss contribution from outward transport calculated using a standard empirical radial diffusion model that assumes a dipolar geomagnetic field to an event-specific radial diffusion model evaluated with a non-dipolar geomagnetic field. We additionally evaluate the contribution of Shabansky type 1 particles, which bounce along magnetic field lines with local equatorial maxima, to the loss calculated during this event. We find that the empirical radial diffusion model with a dipolar background field underestimates the contribution of radial diffusion to this dropout event by up to 10% when compared to the event-specific, non-dipolar radial diffusion model. We additionally find that including Shabansky type 1 particles in the initial electron phase space density, that is, allowing some magnetic field lines distorted from the typical single-minima configuration in drift shell construction, increases the calculated loss by an average of 0.75%. This shows that the treatment of the geomagnetic field significantly impacts the calculation of electron losses to the magnetopause during dropout events, with the non-dipolar treatment of radial diffusion being essential to accurately quantify the loss of outer radiation belt populations.
RESUMEN
BACKGROUND: Meaningful, valid and reliable self-report measures can facilitate the identification of important parent-infant-relationship factors, relevant intervention development and subsequent evaluation in community and clinical contexts. We aimed at identifying all available parent-report measures of the parent-infant-relationship or bond and to appraise their psychometric and clinimetric properties. METHOD: A systematic review (PROSPERO: CRD42017078512) was conducted using the, 2018 COSMIN criteria. Eight electronic databases were searched. Papers describing the development of self-report measures of the parent-infant-bond, attachment or relationship from pregnancy until two years postpartum or the assessment of their psychometric properties were included. RESULTS: Sixty-five articles evaluating 17 original measures and 13 modified versions were identified and reviewed. The studies' methodological quality (risk of bias) varied between 'very good' and 'inadequate' depending on the measurement property assessed; however, scale development studies were mostly of 'inadequate' quality. Although most measures had good clinical utility, the psychometric evaluation of their properties was largely poor. The original or modified versions of the Postpartum Bonding Questionnaire collectively received the strongest psychometric evaluation ratings with high quality of evidence. CONCLUSIONS: This novel review revealed that only a few antenatal and postnatal measures demonstrated adequate psychometric properties. Further studies are needed to determine the most robust perinatal measures for researchers and clinicians.

BACKGROUND: The advent of effective adjuvant therapies for patients with resected melanoma has highlighted the need to stratify patients based on risk of relapse given the cost and toxicities associated with treatment. Here we assessed circulating tumor DNA (ctDNA) to predict and monitor relapse in resected stage III melanoma. PATIENTS AND METHODS: Somatic mutations were identified in 99/133 (74%) patients through tumor tissue sequencing. Personalized droplet digital PCR (ddPCR) assays were used to detect known mutations in 315 prospectively collected plasma samples from mutation-positive patients. External validation was performed in a prospective independent cohort (n = 29). RESULTS: ctDNA was detected in 37 of 99 (37%) individuals. In 81 patients who did not receive adjuvant therapy, 90% of patients with ctDNA detected at baseline and 100% of patients with ctDNA detected at the postoperative timepoint relapsed at a median follow up of 20 months. ctDNA detection predicted patients at high risk of relapse at baseline [relapse-free survival (RFS) hazard ratio (HR) 2.9; 95% confidence interval (CI) 1.5-5.6; P = 0.002] and postoperatively (HR 10; 95% CI 4.3-24; P < 0.001). ctDNA detection at baseline [HR 2.9; 95% CI 1.3-5.7; P = 0.003 and postoperatively (HR 11; 95% CI 4.3-27; P < 0.001] was also associated with inferior distant metastasis-free survival (DMFS). These findings were validated in the independent cohort. ctDNA detection remained an independent predictor of RFS and DMFS in multivariate analyses after adjustment for disease stage and BRAF mutation status. CONCLUSION: Baseline and postoperative ctDNA detection in two independent prospective cohorts identified stage III melanoma patients at highest risk of relapse and has potential to inform adjuvant therapy decisions.

BACKGROUND: The opioid prescribing patterns of orthopedic surgeons have been shown to play a role in exacerbating rates of opioid misuse among post-surgical patients. Demonstrable success has been appreciated by combining policy-level approaches and clinical education-based strategies to inform patients of alternative modalities of post-operative analgesia. QUESTIONS/PURPOSES: The purpose of this review was to address two questions: What are the most substantiated measures orthopedic surgeons can take to limit opioid misuse or addiction among their patients? What advantages are gained in orthopedic surgeons' collaborating with other healthcare professionals with influence over patients' post-operative opioid exposure? METHODS: We searched two databases for articles on multidisciplinary policy-based solutions to mitigating the opioid overdose crisis among musculoskeletal patients. Articles produced from the search were searched for further evidence supporting the use of standardized clinical and administrative protocols in mitigating opioid misuse within this patient population. Successful approaches to mitigating misuse of opioids in this demographic were synthesized from recurring themes in the studies. RESULTS: Multiple articles support orthopedic surgeons being aware of the risk factors for chronic opioid use among their patients, as well as multidisciplinary strategies involving orthopedic surgeons and other healthcare/governmental professionals to address the burden of the opioid crisis on surgical patients. CONCLUSIONS: Addressing the misuse of opioids among orthopedic patients requires appropriate prescribing practices and long-term support of patients. Collaboration between surgeons and policymaking entities is recognized as an effective population-wide approach to preventing opioid dependence, misuse, and addiction.
RESUMEN
OBJECTIVE: Successful healthcare integration demands an understanding of current service utilisation by people with comorbidity. Physical illness may impact on mental health service use (MHSU), but longitudinal studies of comorbidity and MHSU are rare. This study 1) estimated associations between mental-physical comorbidity and longitudinal MHSU patterns; 2) tested whether associations between comorbidity and continuous MHSU are driven by "need". METHODS: Survey data from a South East London community cohort were used (Nâ¯=â¯1052). Common mental disorder symptoms (CMDS) were measured using the Clinical Interview Schedule Revised and self-report of long-standing disorders. A checklist of common conditions measured chronic physical conditions. MHSU captured self-reported use of mental health services in the past year at two time points. "Need" indicators included CMDS at follow-up, suicidal ideation, somatic symptom severity, self-rated health, daily functioning problems and perceived functioning limitations due to emotional health. Analyses used logistic and multinomial regression. RESULTS: Continuous MHSU (at both time-points) was twice as commonly reported by those with comorbidity than those without physical comorbidity (30.9% vs 12.3%). CMDS at follow-up, suicidal ideation, and perceived functioning limitations due to emotional health only partially explained the association between CMDS-physical comorbidity and continuous MHSU. In the adjusted model, comorbidity remained associated with continuous MHSU (RRRâ¯=â¯3.23, 95% CI: 1.39-7.51; pâ¯=â¯.002), while the association for non-comorbid CMDS was fully attenuated (RRRâ¯=â¯1.08, 95% CI: 0.40-2.93; pâ¯=â¯.85). CONCLUSION: CMDS-physical comorbidity was strongly associated with continuous MHSU, and "need" did not account for this association, suggesting that comorbidity itself represents a "need" indicator.

A prospective study explored the heterogeneous nature of metastatic melanoma using Multiplex immunohistochemistry (IHC) and flow cytometry (FACS). Multiplex IHC data quantitated immune subset number present intra-tumoral (IT) vs the tumor stroma, plus distance of immune subsets from the tumor margin (TM). In addition, mIHC showed a close association between the presence of IT CD8+ T cells and PDL1 expression in melanoma, which was more prevalent on macrophages than on melanoma cells. In contrast, FACS provided more detailed information regarding the T cell subset differentiation, their activation status and expression of immune checkpoint molecules. Interestingly, mIHC detected significantly higher Treg numbers than FACS and showed preferential CD4+ T cell distribution in the tumor stroma. Based on the mIHC and FACS data, we provide a model which defines metastatic melanoma immune context into four categories using the presence or absence of PDL1+ melanoma cells and/or macrophages, and their location within the tumor or on the periphery, combined with the presence or absence of IT CD8+ T cells. This model interprets melanoma immune context as a spectrum of tumor escape from immune control, and provides a snapshot upon which interpretation of checkpoint blockade inhibitor (CBI) therapy responses can be built.

Background: As early detection of recurrent melanoma maximizes treatment options, patients usually undergo post-operative imaging surveillance, increasingly with FDG-PET/CT (PET). To assess this, we evaluated stage 3 melanoma patients who underwent prospectively applied and sub-stage-specific schedules of PET surveillance. Patients and methods: From 2009, patients with stage 3 melanoma routinely underwent PET +/- MRI brain scans via defined schedules based on sub-stage-specific relapse probabilities. Data were collected regarding patient characteristics and outcomes. Contingency analyses were carried out of imaging outcomes. Results: One hundred and seventy patients (stage 3A: 34; 3B: 93; 3C: 43) underwent radiological surveillance. Relapses were identified in 65 (38%) patients, of which 45 (69%) were asymptomatic. False-positive imaging findings occurred in 7%, and 6% had treatable second (non-melanoma) malignancies. Positive predictive values (PPV) of individual scans were 56%-83%. Negative scans had predictive values of 89%-96% for true non-recurrence [negative predictive values (NPV)] until the next scan. A negative PET at 18 months had NPVs of 80%-84% for true non-recurrence at any time in the 47-month (median) follow-up period. Sensitivity and specificity of the overall approach of sub-stage-specific PET surveillance were 70% and 87%, respectively. Of relapsed patients, 33 (52%) underwent potentially curative resection and 10 (16%) remained disease-free after 24 months (median). Conclusions: Application of sub-stage-specific PET in stage 3 melanoma enables asymptomatic detection of most recurrences, has high NPVs that may provide patient reassurance, and is associated with a high rate of detection of resectable and potentially curable disease at relapse.
