However, research has only recently begun to investigate selfies, and little is known about selfie practices in adolescents, or the associations between these practices and well-being and body confidence. This paper aimed to address this gap and conduct a narrative review of selfie practices and the relationships with well-being and body confidence in adolescents. No studies were found reporting on selfie practices and these relationships among children. However, taking selfies appears to be common practice among adolescents, although posting selfies online is less frequent. The studies reviewed indicate that certain aspects of selfie behaviors may be more problematic than others. Specifically, viewing selfies online appears to have a negative impact on adolescents’ well-being and body confidence, at least in the short term in experimental contexts. Moreover, seeking and placing importance on feedback from others may also be a harmful aspect of selfie practices. Finally, consistent with research examining social media, social comparison has been identified in this emerging body of research as a potential mechanism which links selfie engagement to well-being and body confidence. To further advance understanding of the correlates and effects of selfie practices, research with children and with boys, and research focused on a wider range of indicators of well-being, is needed. Most importantly, prospective research is required to examine the directionality of links between selfie practices and well-being and body confidence.Keywords: selfies, social media, adolescents, well-being, body image, social comparison

Pain is common after sexual assault (SA), but etiology of pain symptoms after SA is unknown. Preclinical studies suggest that the release of endogenous opioids during stress produces delayed-onset hyperalgesia. In human studies, individuals with >=1 G allele at the [mu]-opioid receptor functional single nucleotide polymorphism A118G have been shown to have a reduced response to opioids. We hypothesized that if opioid-mediated hyperalgesia contributes to pain after SA, women SA survivors with 1 or more G alleles at A118G would experience reduced postassault pain. Among 52 European American women SA survivors presenting for care within 48 hours of SA, those with a G allele (12/52, 23%) experienced less severe pain (F[1,39] = 11.55, P = .002) and a reduced extent of pain (F[1,41] = 11.01, P = .002) during the 6 weeks after SA. These associations between the presence of 1 or more G alleles and reduced pain severity and reduced pain extent after SA remained significant in multivariable models controlling for age, income, education, reported pain prior to assault, and pain at the time of initial evaluation. PERSPECTIVE: These results suggest that endogenous opioid-mediated hyperalgesia may contribute to pain symptoms after sexual assault. Further studies examining mechanisms mediating the development of pain after sexual assault, and the potential influence of opioid-mediated hyperalgesia, are needed. [ABSTRACT FROM AUTHOR]

OBJECTIVE: To compare the momentary association between salivary cortisol levels and pain, fatigue, and stress symptoms in patients with fibromyalgia (FM), and to compare diurnal cycles of cortisol secretion in patients with FM and healthy control subjects in a naturalistic environment. METHODS: Twenty-eight patients with FM and 27 healthy control subjects completed assessments on salivary cortisol levels and pain, fatigue, and stress symptoms, 5 times a day for 2 consecutive days, while engaging in usual daily activities. Only those participants who adhered to the protocol (assessed via activity monitor) were included in the final analyses. RESULTS: Twenty FM patients and 16 healthy control subjects adhered to the protocol. There were no significant differences in cortisol levels or diurnal cortisol variation between FM patients and healthy controls. Among women with FM, a strong relationship between cortisol level and current pain symptoms was observed at the waking time point (t = 3.35, P = 0.008) and 1 hour after waking (t = 2.97, P = 0.011), but not at the later 3 time points. This association was not due to differences in age, number of symptoms of depression, or self-reported history of physical or sexual abuse. Cortisol levels alone explained 38% and 14% of the variation in pain at the waking and 1 hour time points, respectively. No relationship was observed between cortisol level and fatigue or stress symptoms at any of the 5 time points. CONCLUSION: Among women with FM, pain symptoms early in the day are associated with variations in function of the hypothalamic-pituitary-adrenal axis. [ABSTRACT FROM AUTHOR]

Purpose. Fibromyalgia (FM) and chronic widespread pain (CWP) are common, but the etiology of these disorders remains poorly understood. A large body of data indicates a neurobiological basis for these disorders, but this information has not been effectively transmitted to many medical professionals. Methods. Contemporary data on the epidemiologic characteristics of FM and CWP are reviewed, and evidence for a neurobiological basis for these disorders is presented. In addition, possible predisposing, triggering, and maintaining factors for the development of these disorders are discussed. Results. Approximately 10% of the population have CWP, and approximately 4% have FM. The tender point criteria for FM have resulted in the common misconception among health care professionals that this spectrum of disorders is limited to women with high degrees of psychological distress. A hallmark of FM is the presence of non-nociceptive, central pain. There is evidence of centrally augmented pain processing, which can be detected both with sensory testing and by more objective measures (e.g., evoked potentials, functional neuroimaging). Discussion. An appreciation of the neurobiological basis for these disorders, and an understanding of some of the abnormalities of pain processing present in patients with FM, will hopefully provide greater understanding of these patients. It may also serve to decrease the level of frustration and improve the care experience of both chronic pain patients and physicians. [ABSTRACT FROM AUTHOR]

Abstract Background Persistent musculoskeletal pain and psychological sequelae following minor motor vehicle collision (MVC) are common problems with a large economic cost. Prospective studies of pain following MVC have demonstrated that demographic characteristics, including female gender and low education level, and psychological characteristics, including high pre-collision anxiety, are independent predictors of persistent pain. These results have contributed to the psychological and social components of a biopsychosocial model of post-MVC pain pathogenesis, but the biological contributors to the model remain poorly defined. Recent experimental studies indicate that genetic variations in adrenergic system function influence the vulnerability to post-traumatic pain, but no studies have examined the contribution of genetic factors to existing predictive models of vulnerability to persistent pain. Methods/Design The Project CRASH study is a federally supported, multicenter, prospective study designed to determine whether variations in genes affecting synaptic catecholamine levels and alpha and beta adrenergic receptor function augment social and psychological factors in a predictive model of persistent musculoskeletal pain and posttraumatic stress disorder (PTSD) following minor MVC. The Project CRASH study will assess pain, pain interference and PTSD symptoms at 6 weeks, 6 months, and 1 year in approximately 1,000 patients enrolled from 8 Emergency Departments in four states with no-fault accident laws. Discussion The results from this study will provide insights into the pathophysiology of persistent pain and PTSD following MVC and may serve to improve the ability of clinicians and researchers to identify individuals at high risk for adverse outcomes following minor MVC.

STUDY DESIGN: Nonsystematic review and discussion of the etiological processes involved in whiplash-associated disorders (WAD). OBJECTIVE: To summarize the research and identify priorities for future research. SUMMARY OF BACKGROUND DATA: Although there is convergent evidence of a peripheral lesion in some individuals after whiplash injury, in the majority of injured people, a lesion cannot be established with current imaging technology. Therefore, it is important to consider processes that underlie the initiation and maintenance of whiplash pain as this may allow for the development and testing of interventions to target these processes and improve outcomes. METHODS: A nonsystematic review was performed to summarize current knowledge regarding potential etiological processes involved in the initiation and maintenance of WAD and to identify future research priorities. RESULTS: There are several etiological processes potentially involved in the initiation and maintenance of WAD. These include augmented nociceptive processing, stress system responses, and psychosocial and sociocultural factors. Recent findings also indicate that morphological changes in the neck muscles of injured people show some association with poor recovery, but the mechanisms underlying these changes are not clear. Preliminary evidence indicates associations between these processes. Future research priorities include the following: more sophisticated investigation and analysis of interactions between the various processes; whether the modification of these processes is achievable and if modification can improve health outcomes; and to clarify factors involved in the initiation of whiplash pain versus those involved in symptom maintenance. CONCLUSION: Research to date indicates that there are several physiological and psychological etiological processes that may underlie the initiation and maintenance of whiplash-related pain and disability. Further research is required to determine relationships and interactions between these factors and to determine whether their modification is possible and will improve outcomes after injury.

Adverse posttraumatic neuropsychiatric sequelae (APNS) are common after traumatic events. We examined whether wrist-wearable devices could provide heart rate variability (HRV) biomarkers for recovery after traumatic stress exposure in a large socioeconomically disadvantaged cohort. Participants were enrolled in the emergency department within 72 hours after a traumatic event as part of the AURORA (Advancing Understanding of RecOvery afteR traumA) multicenter prospective observational cohort study and followed over 6 months. HRV biomarkers were derived and validated for associations with specific APNS symptoms at a point in time and changes in symptom severity over time. Sixty-four HRV characteristics were derived and validated as cross-sectional biomarkers of APNS symptoms, including pain (26), re-experiencing (8), somatic (7), avoidance (7), concentration difficulty (6), hyperarousal (5), nightmares (1), anxiety (1), and sleep disturbance (3). Changes in 22 HRV characteristics were derived and validated as biomarkers identifying changes in APNS symptoms, including reexperiencing (11), somatic (3), avoidance (2), concentration difficulty (1), hyperarousal (1), and sleep disturbance (4). Changes in HRV variables over time predicted symptom improvement (PPV 0.68-0.87) and symptom worsening (NPV 0.71-0.90). HRV biomarkers collected from wrist-wearable devices may have utility as screening tools for APNS symptoms that occur after traumatic stress exposure in high-risk populations., Competing Interests: Declaration of competing interest Dr. Neylan has received research support from NIH, VA, and Rainwater Charitable Foundation, and consulting income from Jazz Pharmaceuticals.

Unfortunately, survivors of traumatic stress exposure (TSE) frequently develop adverse posttraumatic neuropsychiatric sequelae (APNS) such as chronic pain and stress/depressive symptoms. Increasing evidence indicates that there is a 'window of opportunity' following TSE in which therapeutic interventions are most effective against APNS, yet mechanisms accounting for this observation are poorly understood. Here, we aimed to better understand such mechanisms by generating snapshots of the transcriptional landscape in the early aftermath of TSE across tissues and time. Adult rats were exposed to a TSE model, single prolonged stress (SPS). Then, eight tissues (hypothalamus, left and right hippocampus, amygdala, dorsal root ganglia, spinal cord, heart, and muscle) were isolated from these animals at 2, 24, and 72 hours after SPS and in unexposed controls (n=6 per group). mRNA expression from deep sequencing was used to identify differentially expressed genes (DEGs) and biological pathways enriched over time. In all tissues except the amygdala, the highest number of DEGs was observed 2-hours post-SPS, but DEGs were detected at all timepoints and in all tissues. Some transcripts were differentially expressed in a consistent manner across multiple tissues at a time point (e.g. Fkbp5, 2 hours post-SPS), while others had tissue- or region-specific expression patterns. Stress system pathways were most represented at 2-hours post-SPS, then stress/circadian/inflammatory pathways at 24-hours, and inflammatory pathways at 72-hours. Together these findings provide insights into post-TSE transcriptional landscape dynamics and suggest specific intervention windows of opportunity. Future validation is needed across sex, age, stressor, and cell type.

Squamoid eccrine ductal carcinoma is a rare infiltrative tumor with morphologic features intermediate between squamous cell carcinoma (SCC) and sweat gland carcinomas such as microcystic adnexal carcinoma. Although currently classified as a sweat gland carcinoma, it has been debated whether squamoid eccrine ductal carcinoma is better classified as a variant of SCC. Furthermore, therapeutic options for patients with advanced disease are lacking. Here, we describe clinicopathologic features of a cohort of 15 squamoid eccrine ductal carcinomas from 14 unique patients, with next-generation sequencing DNA profiling for 12 cases. UV signature mutations were the dominant signature in the majority of cases. TP53 mutations were the most highly recurrent specific gene alteration, followed by mutations in NOTCH genes. Recurrent mutations in driver oncogenes were not identified. By unsupervised comparison of global transcriptome profiles in squamoid eccrine ductal carcinoma (n = 7) to SCC (n = 10), porocarcinoma (n = 4), and microcystic adnexal carcinoma (n = 4), squamoid eccrine ductal carcinomas displayed an intermediate phenotype between SCC and sweat gland tumors. Squamoid eccrine ductal carcinoma displayed significantly higher expression of 364 genes (including certain eccrine markers) and significantly lower expression of 525 genes compared with other groups. Our findings support the classification of squamoid eccrine ductal carcinoma as a carcinoma with intermediate features between SCC and sweat gland carcinoma., (Copyright © 2024 United States & Canadian Academy of Pathology.

Research has revealed an important role for appearance-focused, and in particular photo-based, social media in the development of body image and eating pathology. Social media literacy is a multifaceted construct involving purposeful selection and exposure to social media content and use of protective filtering (deliberately screening and interpreting information in a protective manner), as well as implementing critical skills related to understanding the unrealistic nature of social media content, limiting appearance comparisons with images, and contributing to social media (comments and images) in ways that limit the pursuit of appearance ideals. Previous work has provided partial support for these facets as related to lower levels of body image and eating concerns. However, additional conceptual and measurement work is needed to advance understanding of this protective role and how to foster social media literacy. Although data are scarce, targeting social media literacy in prevention and intervention programs may also be valuable. In this perspective piece, key features that we identify as priorities for future prevention and intervention efforts include developing interventions that target the implementation of social media skills beyond their acquisition. In addition, leveraging social media user generated content for prevention purposes would likely be useful, as would embedding micro-skill delivery within platforms.

Importance: Research on resilience after trauma has often focused on individual-level factors (eg, ability to cope with adversity) and overlooked influential neighborhood-level factors that may help mitigate the development of posttraumatic stress disorder (PTSD)., Objective: To investigate whether an interaction between residential greenspace and self-reported individual resources was associated with a resilient PTSD trajectory (ie, low/no symptoms) and to test if the association between greenspace and PTSD trajectory was mediated by neural reactivity to reward., Design, Setting, and Participants: As part of a longitudinal cohort study, trauma survivors were recruited from emergency departments across the US. Two weeks after trauma, a subset of participants underwent functional magnetic resonance imaging during a monetary reward task. Study data were analyzed from January to November 2023., Exposures: Residential greenspace within a 100-m buffer of each participant's home address was derived from satellite imagery and quantified using the Normalized Difference Vegetation Index and perceived individual resources measured by the Connor-Davidson Resilience Scale (CD-RISC)., Main Outcome and Measures: PTSD symptom severity measured at 2 weeks, 8 weeks, 3 months, and 6 months after trauma. Neural responses to monetary reward in reward-related regions (ie, amygdala, nucleus accumbens, orbitofrontal cortex) was a secondary outcome. Covariates included both geocoded (eg, area deprivation index) and self-reported characteristics (eg, childhood maltreatment, income)., Results: In 2597 trauma survivors (mean [SD] age, 36.5 [13.4] years; 1637 female [63%]; 1304 non-Hispanic Black [50.2%], 289 Hispanic [11.1%], 901 non-Hispanic White [34.7%], 93 non-Hispanic other race [3.6%], and 10 missing/unreported [0.4%]), 6 PTSD trajectories (resilient, nonremitting high, nonremitting moderate, slow recovery, rapid recovery, delayed) were identified through latent-class mixed-effect modeling. Multinominal logistic regressions revealed that for individuals with higher CD-RISC scores, greenspace was associated with a greater likelihood of assignment in a resilient trajectory compared with nonremitting high (Wald z test = -3.92; P < .001), nonremitting moderate (Wald z test = -2.24; P = .03), or slow recovery (Wald z test = -2.27; P = .02) classes. Greenspace was also associated with greater neural reactivity to reward in the amygdala (n = 288; t277 = 2.83; adjusted P value = 0.02); however, reward reactivity did not differ by PTSD trajectory., Conclusions and Relevance: In this cohort study, greenspace and self-reported individual resources were significantly associated with PTSD trajectories. These findings suggest that factors at multiple ecological levels may contribute to the likelihood of resiliency to PTSD after trauma.

Objective: A minority of individuals with eating disorders seek help from health professionals qualified to provide eating disorder care. This review assessed the proportion of individuals with eating disorders who had sought help or received treatment, as an update to an earlier review conducted more than a decade ago., Method: Three databases were searched for studies that: (1) included a community sample of help-seekers and non-help seekers, (2) used a standardized eating disorder screening instrument, and (3) assessed the percentage of participants who had sought help specifically for eating disorder concerns., Results: Of 972 articles, 21 studies met inclusion criteria, representing 37,423 participants. The pooled proportion reporting help-seeking from any source (e.g., helpline, support groups, chat rooms as well as health professionals) was 30% and the pooled proportion reporting formal treatment seeking from health professionals (e.g., psychologist) specifically for eating disorder concerns was 32%. However, there was evidence of publication bias across studies., Discussion: These rates suggest little to no improvement in the unmet need for treatment since the last review with studies continuing to focus on white adult women. Help-seeking rates among other populations remain unclear and there is an urgent need to understand reasons for overall low help-seeking rates. Clear definitions and measures of help-seeking with appropriate distinctions between sources of help are needed to improve our understanding of help-seeking pathways and identify solutions to facilitate help-seeking. Better visibility of health professionals qualified to provide safe and effective eating disorder care could help reduce the substantial treatment gap., (© 2024 Wiley Periodicals LLC.)

Objectives: To determine the relative 5-year overall survival (OS) and 5-year recurrence-free survival (RFS) outcomes for adjuvant interferon therapy in the treatment of head and neck cutaneous melanoma (HNCM) with parotid gland involvement., Methods: A retrospective cohort study was conducted at a single tertiary care institution to analyze patients undergoing parotidectomy for cutaneous head and neck melanoma involving the parotid gland from 2000 to 2014. Time-to-event analyses were performed using Kaplan-Meier curves with log-rank p-values and Cox proportional hazards models., Results: The sample consisted of 82 patients who underwent surgical resection of stage III HNCM with parotid involvement. The mean follow-up was 67.8 months (SD 65) after diagnosis. Twenty-one patients received adjuvant interferon therapy, 12 patients received adjuvant radiation therapy, and 49 patients received no adjuvant therapy. Crude 5-year OS rates were 95.0% for interferon therapy, 33.3% for adjuvant RT, and 40.4% for no adjuvant therapy. Crude 5-year RFS rates were 75.2%, 19.5%, and 40.8% respectively. In the fully adjusted model, adjuvant interferon therapy was associated with improved 5-year OS compared to adjuvant RT (HR 0.10, 95% CI 0.011-0.837; p = 0.034). There was no significant association between adjuvant interferon therapy and 5-year RFS in the fully adjusted model., Conclusion: Adjuvant interferon therapy for surgically resected stage III cutaneous melanoma with parotid gland involvement may be associated with improved survival outcomes. These findings support the growing evidence for the use of immunotherapy in melanoma, and potentially a unique role for when melanoma involves the lymphatic-rich parotid gland., Level of Evidence: 3 Laryngoscope, 2024., (© 2024 The Author(s).

Background: Trauma is a risk factor for developing maladaptive alcohol use. Preclinical research has shown that stress alters the processing of midbrain and striatal reward and incentive signals. However, little research has been conducted on alterations in reward-related neurocircuitry post-trauma in humans. Neuroimaging markers may be particularly useful as they can provide insight into the mechanisms that may make an individual vulnerable to developing trauma-related psychopathologies. This study aimed to identify reward-related neural correlates associated with changes in alcohol use after trauma exposure., Methods: Participants were recruited from U.S. emergency departments for the AURORA study (N=286, 178 female). Trauma-related change in alcohol use at 8 weeks post-trauma relative to pre-trauma was quantified as a change in 30-day total drinking per the PhenX Toolkit Alcohol 30-Day Quantity and Frequency Measure. Reward-related neurocircuitry activation and functional connectivity (FC) were assessed 2 weeks post-trauma using fMRI during a monetary reward task using region of interest and whole-brain voxelwise analyses., Results: Greater increase in alcohol use from pre-trauma to 8 weeks post-trauma was predicted by (1) greater ventral tegmental area (VTA) and (2) greater cerebellum activation during Gain>Loss trials measured 2 weeks post-trauma and (3) greater seed-based FC between the VTA and lateral occipital cortex and precuneus., Conclusions: Altered VTA activation and FC early post-trauma may be associated with reward-seeking and processing, contributing to greater alcohol use post-trauma. These data provide novel evidence of neural correlates that underlie increased alcohol use early post-trauma that may be targeted via early interventions to prevent the development of maladaptive alcohol use., (Copyright © 2024.

Objective: Compare full-thickness skin grafts versus split-thickness skin grafts in scalp reconstruction., Study Design: Retrospective chart review of patients who underwent scalp reconstruction with skin grafts performed at a single institution from 2011 to 2016., Methods: χ 2 or Fisher exact tests were used to compare graft integration and complication rates. The effects of graft type, defect type, graft size, and patient comorbidities on the likelihood of graft success and complications were analyzed using multivariate logistic regression., Results: A hundred and twenty-five full-thickness and 93 split-thickness grafts were performed in 200 patients, including 68 defects (31.2%) with exposed calvarium. Full-thickness grafts required fewer average reconstructions (P = 0.002). A 92.8% of full-thickness grafts had complete graft integration compared with 78.5% of split-thickness grafts (P = 0.002). This difference was more evident in defects with exposed calvarium (87.2% vs. 47.6%, P ≤ 0.001). Despite higher rates of minor debridement, full-thickness grafts had less postoperative bone exposure and wound breakdown than split-thickness grafts on intact pericranium and exposed calvarium defects. Preoperative radiation, immunosuppression, and increased graft sizes were significant predictors of graft outcomes., Conclusions: Skin grafts, especially full-thickness, provide a versatile, reliable, and simple approach for reconstructing medium to large scalp defects in the appropriate patient. Even on defects with bare calvarium, full-thickness grafts can succeed when a vascularized recipient bed is prepared. Defects with exposed bone, larger graft sizes, preoperative radiation, and immunosuppression may result in decreased graft take and increased complications., Level of Evidence: 3b., Competing Interests: Declaration of Competing Interest None of the contributing authors have any financial disclosures or conflicts of interest., (Copyright © 2024.

A barrier to research with sexual assault survivors is the concern that research participation might be a negative experience for participants. We report the experiences with research of adult women sexual assault survivors participating in a large-scale, multi-site, prospective observational study that enrolled participants at the time of presentation for emergency care. Participants (n = 706, M = 28 years of age; 57% white, 15% Black) self-reported their experience with research 1 week, 6 weeks, 6 months, and 1 year post-assault. The vast majority rated the research experience as positive (95-97%), reported no drawbacks (84-89%), and felt that participating was worth it (93-95%). Positive experiences with research remained stable across the year, were generally consistent across demographic and clinical groups, and were reflected in qualitative comments. Given the tremendous morbidity experienced by sexual assault survivors and lack of progress in developing improved treatments for this population, ethically-conducted research with sexual assault survivors receiving emergency care should be encouraged., Competing Interests: Declaration of competing interest Dr. Short received grant funding from the National Institute on Drug Abuse for a separate study.

While much research has explored the impacts of social media use, less is known about what factors drive use. The present study examined the relationships between potential drivers of social media use; namely social media literacy, motivations, and internalisation of appearance ideals, and determined whether they work in combination or individually to predict a range of social media uses and behaviours over time, including intensity, frequency, exposure to fitness and celebrity content, photo editing, appearance comparisons, and types of use. Australian adolescent girls (n = 704) and boys (n = 938) aged 11-16 years completed online surveys at baseline and 6-month follow-up. Bivariate correlations and multiple regressions were performed separately by gender. Results revealed weak associations between drivers and found they uniquely contributed to social media behaviours, though this was dependent on use outcome. Thin- and muscular-internalisation were related to some appearance-focused use (e.g., comparisons, following celebrity and fitness accounts) among girls and boys, respectively. Critical thinking was associated with lower Snapchat use among boys and motivations were related to intensity and type of use (i.e., viewing, posting). These findings suggest multicomponent holistic interventions targeting numerous drivers may be most appropriate in modifying social media behaviours among adolescents., Competing Interests: Declaration of Competing Interest The authors have no known conflict of interests to disclose., (Copyright © 2024 The Authors.

Abstract: Chronic posttraumatic pain (CPTP) is common after traumatic stress exposure (TSE) and disproportionately burdens women. We previously showed across 3 independent longitudinal cohort studies that, in women, increased peritraumatic 17β-estradiol (E2) levels were associated with substantially lower CPTP over 1 year. Here, we assessed this relationship in a fourth longitudinal cohort and also assessed the relationship between E2 and CPTP at additional time points post-TSE. Furthermore, we used a well-validated animal model of TSE to determine whether exogenous E2 administration protects against mechanical hypersensitivity. Using nested samples and data from the Advancing Understanding of RecOvery afteR traumA study (n = 543 samples, 389 participants), an emergency department-based prospective study of TSE survivors, we assessed the relationship between circulating E2 levels and CPTP in women and men using multivariate repeated-measures mixed modeling. Male and ovariectomized female Sprague Dawley rats were exposed to TSE and administered E2 either immediately after or 3 days post-TSE. Consistent with previous results, we observed an inverse relationship between peritraumatic E2 and longitudinal CPTP in women only (β = -0.137, P = 0.033). In animals, E2 protected against mechanical hypersensitivity in female ovariectomized rats only if administered immediately post-TSE. In conclusion, peritraumatic E2 levels, but not those at post-TSE time points, predict CPTP in women TSE survivors. Administration of E2 immediately post TSE protects against mechanical hypersensitivity in female rats. Together with previous findings, these data indicate that increased peritraumatic E2 levels in women have protective effects against CPTP development and suggest that immediate post-TSE E2 administration in women could be a promising therapeutic strategy for reducing risk of CPTP., (Copyright © 2024 International Association for the Study of Pain.)

Background: Large full-thickness lip defects present a reconstructive challenge., Objective: To describe the impact on clinical outcomes and institutional cost of the depressor anguli oris myocutaneous (DAOM) flap as an axial pattern transposition flap for reconstruction of large, full-thickness lip defects., Methods: A multicenter retrospective cohort study of adults with large full-thickness lip defects who underwent DAOM flap reconstruction from 2011 to 2018 was conducted. DAOM flap anatomy and surgical technique were reviewed. The primary outcome of flap viability as well as additional clinical outcomes of postoperative complications and functional results were documented with follow-up ranging up to 11 years. Median length of stay and average institutional cost of care were analyzed., Results: A total of 12 patients underwent DAOM flap reconstruction for large full-thickness lip defects. There was 100% flap survival with no episodes of reoperation or readmission. All patients reported maintenance of distinct oral commissures, wide oral opening and full gingivolabial sulcus, excellent oral competence, and intelligible speech. Mean case length was 144 ± 11.5 min with a mean length of stay of 1.6 ± 0.5 days and estimated mean institutional cost of $3766.67 ± $1167.06., Conclusions: The DAOM flap is an excellent reconstructive option for large full-thickness lip defects with strong functional results and limited donor site morbidity and institutional cost of care., Competing Interests: Declaration of Competing Interest None declared., (Copyright © 2023.

The neurocardiac circuit is integral to physiological regulation of threat and trauma-related responses. However, few direct investigations of brain-behavior associations with replicable physiological markers of PTSD have been conducted. The current study probed the neurocardiac circuit by examining associations among its core regions in the brain (e.g., insula, hypothalamus) and the periphery (heart rate [HR], high frequency heart rate variability [HF-HRV], and blood pressure [BP]). We sought to characterize these associations and to determine whether there were differences by PTSD status. Participants were N = 315 (64.1 % female) trauma-exposed adults enrolled from emergency departments as part of the prospective AURORA study. Participants completed a deep phenotyping session (e.g., fear conditioning, magnetic resonance imaging) two weeks after emergency department admission. Voxelwise analyses revealed several significant interactions between PTSD severity 8-weeks posttrauma and psychophysiological recordings on hypothalamic connectivity to the prefrontal cortex (PFC), insula, superior temporal sulcus, and temporoparietaloccipital junction. Among those with PTSD, diastolic BP was directly correlated with right insula-hypothalamic connectivity, whereas the reverse was found for those without PTSD. PTSD status moderated the association between systolic BP, HR, and HF-HRV and hypothalamic connectivity in the same direction. While preliminary, our findings may suggest that individuals with higher PTSD severity exhibit compensatory neural mechanisms to down-regulate autonomic imbalance. Additional study is warranted to determine how underlying mechanisms (e.g., inflammation) may disrupt the neurocardiac circuit and increase cardiometabolic disease risk in PTSD., Competing Interests: Declaration of competing interest Dr. Neylan reports consultation for Jazz Pharmaceuticals; Dr. Rauch reports royalties from Oxford University Press, the American Psychiatric Publishing Inc., and Springer Publishing royalties; Dr. McLean reports consultation for Walter Reed Army Institute for Research and for Arbor Medical Innovations; Dr. Kessler reports consultation for Cambridge Health Alliance, Canandaigua VA Medical Center, Holmusk, Partners Healthcare, INC Mirah, PYM, and Roga Sciences; Dr. Koenen reports royalties from Guilford Press and Oxford University Press; Dr. Ressler reports consultation for Bioxcel, Bionomics, Acer, and Jazz Pharma; All other authors report no biomedical financial interests or potential conflicts of interest., (Copyright © 2024 Elsevier Ltd.

Background: The occurrence of post-traumatic stress disorder (PTSD) following a traumatic event is associated with biological differences that can represent the susceptibility to PTSD, the impact of trauma, or the sequelae of PTSD itself. These effects include differences in DNA methylation (DNAm), an important form of epigenetic gene regulation, at multiple CpG loci across the genome. Moreover, these effects can be shared or specific to both central and peripheral tissues. Here, we aim to identify blood DNAm differences associated with PTSD and characterize the underlying biological mechanisms by examining the extent to which they mirror associations across multiple brain regions., Methods: As the Psychiatric Genomics Consortium (PGC) PTSD Epigenetics Workgroup, we conducted the largest cross-sectional meta-analysis of epigenome-wide association studies (EWASs) of PTSD to date, involving 5077 participants (2156 PTSD cases and 2921 trauma-exposed controls) from 23 civilian and military studies. PTSD diagnosis assessments were harmonized following the standardized guidelines established by the PGC-PTSD Workgroup. DNAm was assayed from blood using either Illumina HumanMethylation450 or MethylationEPIC (850K) BeadChips. A common QC pipeline was applied. Within each cohort, DNA methylation was regressed on PTSD, sex (if applicable), age, blood cell proportions, and ancestry. An inverse variance-weighted meta-analysis was performed. We conducted replication analyses in tissue from multiple brain regions, neuronal nuclei, and a cellular model of prolonged stress., Results: We identified 11 CpG sites associated with PTSD in the overall meta-analysis (1.44e-09 < p < 5.30e-08), as well as 14 associated in analyses of specific strata (military vs civilian cohort, sex, and ancestry), including CpGs in AHRR and CDC42BPB . Many of these loci exhibit blood-brain correlation in methylation levels and cross-tissue associations with PTSD in multiple brain regions. Methylation at most CpGs correlated with their annotated gene expression levels., Conclusions: This study identifies 11 PTSD-associated CpGs, also leverages data from postmortem brain samples, GWAS, and genome-wide expression data to interpret the biology underlying these associations and prioritize genes whose regulation differs in those with PTSD., Competing Interests: Competing interests CYC is an employee of Biogen.

Background: Females are more likely to develop posttraumatic stress disorder (PTSD) than males. Impaired inhibition has been identified as a mechanism for PTSD development, but studies on potential sex differences in this neurobiological mechanism and how it relates to PTSD severity and progression are relatively rare. Here, we examined sex differences in neural activation during response inhibition and PTSD following recent trauma., Methods: Participants (n = 205, 138 female sex assigned at birth) were recruited from emergency departments within 72 hours of a traumatic event. PTSD symptoms were assessed 2 weeks and 6 months posttrauma. A Go/NoGo task was performed 2 weeks posttrauma in a 3T magnetic resonance imaging scanner to measure neural activity during response inhibition in the ventromedial prefrontal cortex, right inferior frontal gyrus, and bilateral hippocampus. General linear models were used to examine the interaction effect of sex on the relationship between our regions of interest and the whole brain, PTSD symptoms at 6 months, and symptom progression between 2 weeks and 6 months., Results: Lower response inhibition-related ventromedial prefrontal cortex activation 2 weeks posttrauma predicted more PTSD symptoms at 6 months in females but not in males, while greater response inhibition-related right inferior frontal gyrus activation predicted lower PTSD symptom progression in males but not females. Whole-brain interaction effects were observed in the medial temporal gyrus and left precentral gyrus., Conclusions: There are sex differences in the relationship between inhibition-related brain activation and PTSD symptom severity and progression. These findings suggest that sex differences should be assessed in future PTSD studies and reveal potential targets for sex-specific interventions., (Copyright © 2024 Society of Biological Psychiatry.

In the United States, 8,000,000 people seek emergency care for traumatic injury annually. Motor vehicle collisions (MVCs) and sexual assault are two common sources of trauma, with evidence that reduced neighborhood-level socioeconomic characteristics increase posttraumatic pain and stress after an MVC. We evaluated whether neighborhood disadvantage was also associated with physical and mental posttrauma outcomes after sexual assault in a sample of adult women (N = 656) who presented for emergency care at facilities in the United States following sexual assault and were followed for 1 year. Neighborhood characteristics were assessed via the Area Deprivation Index, and self-reported pain, anxiety, depression, and posttraumatic stress disorder (PTSD) symptoms were collected at 6 weeks posttrauma. Adjusted log-binomial regression models examined the association between each clinical outcome and neighborhood disadvantage. Women in more disadvantaged neighborhoods were more likely to be non-White and have lower annual incomes. At 6 weeks posttrauma, the prevalence of clinically significant pain, anxiety, and depressive symptoms more than doubled from baseline (41.7% vs. 18.8%, 62.4% vs. 23.9%, and 55.2% vs. 22.7%, respectively); 40.7% of women also reported PTSD symptoms. Black, Hispanic, and lower-income participants were more likely to report pre- and postassault pain, anxiety, and depression. After adjusting for race, ethnicity, and income, no significant association existed between neighborhood disadvantage and any outcome, ps = .197 - .859. Although neighborhood disadvantage was not associated with posttrauma outcomes, these findings highlight the need for continued research in diverse populations at high risk of adverse physical and mental health symptoms following sexual assault., (© 2024 International Society for Traumatic Stress Studies.)

There are significant challenges to identifying which individuals require intervention following exposure to trauma, and a need for strategies to identify and provide individuals at risk for developing PTSD with timely interventions. The present study seeks to identify a minimal set of trauma-related symptoms, assessed during the weeks following traumatic exposure, that can accurately predict PTSD. Participants were 2185 adults (Mean age=36.4 years; 64% women; 50% Black) presenting for emergency care following traumatic exposure. Participants received a 'flash survey' with 6-8 varying symptoms (from a pool of 26 trauma symptoms) several times per week for eight weeks following the trauma exposure (each symptom assessed ∼6 times). Features (mean, sd, last, worst, peak-end scores) from the repeatedly assessed symptoms were included as candidate variables in a CART machine learning analysis to develop a pragmatic predictive algorithm. PTSD (PCL-5 ≥38) was present for 669 (31%) participants at the 8-week follow-up. A classification tree with three splits, based on mean scores of nervousness, rehashing, and fatigue, predicted PTSD with an Area Under the Curve of 0.836. Findings suggest feasibility for a 3-item assessment protocol, delivered once per week, following traumatic exposure to assess and potentially facilitate follow-up care for those at risk., Competing Interests: Declaration of Competing Interest Dr. Neylan has received research support from NIH, VA, and Rainwater Charitable Foundation, and consulting income from Jazz Pharmaceuticals.
