Patients with posttraumatic stress disorder (PTSD) exhibit smaller regional brain volumes in commonly reported regions including the amygdala and hippocampus, regions associated with fear and memory processing. In the current study, we have conducted a voxel-based morphometry (VBM) meta-analysis using whole-brain statistical maps with neuroimaging data from the ENIGMA-PGC PTSD working group.
Methods
T1-weighted structural neuroimaging scans from 36 cohorts (PTSD n = 1309; controls n = 2198) were processed using a standardized VBM pipeline (ENIGMA-VBM tool). We meta-analyzed the resulting statistical maps for voxel-wise differences in gray matter (GM) and white matter (WM) volumes between PTSD patients and controls, performed subgroup analyses considering the trauma exposure of the controls, and examined associations between regional brain volumes and clinical variables including PTSD (CAPS-4/5, PCL-5) and depression severity (BDI-II, PHQ-9).
Results
PTSD patients exhibited smaller GM volumes across the frontal and temporal lobes, and cerebellum, with the most significant effect in the left cerebellum (Hedges’ g = 0.22, pcorrected = .001), and smaller cerebellar WM volume (peak Hedges’ g = 0.14, pcorrected = .008). We observed similar regional differences when comparing patients to trauma-exposed controls, suggesting these structural abnormalities may be specific to PTSD. Regression analyses revealed PTSD severity was negatively associated with GM volumes within the cerebellum (pcorrected = .003), while depression severity was negatively associated with GM volumes within the cerebellum and superior frontal gyrus in patients (pcorrected = .001).
Conclusions
PTSD patients exhibited widespread, regional differences in brain volumes where greater regional deficits appeared to reflect more severe symptoms. Our findings add to the growing literature implicating the cerebellum in PTSD psychopathology.
On October 3–4, 2023 and September 30–October 1, 2024, the Memorial Sloan Kettering Cancer Center Department of Psychiatry and Behavioral Sciences and Supportive Care Service hosted the 4th and 5th Annual U.S. Celebration of World Hospice and Palliative Care Day (WHPCD) conferences, respectively. This article describes both events and lessons learned in anticipation of the 6th annual conference to be held October 6–7, 2025.
Methods
The 4th and 5th annual events, conference planning team reflection, and attendee evaluation responses are summarized.
Results
Since 2020, the conference has attracted attendees from around the world. Two primary aims continue to guide the event: community building and wisdom sharing at the intersection of art and science. Both the 2023 and 2024 events consisted of 13 unique interactive sessions addressing diverse hospice and palliative care topics delivered by interprofessional experts in palliative care (43 faculty in 2023 and 54 in 2024). Multidisciplinary registrants more than doubled from 764 in 43 countries (2023) to 1678 in 87 countries (2024). Complimentary registration for colleagues in low- and middle-income countries (LMIC), students and trainees, and individuals experiencing financial hardship remains a cornerstone of inclusion and equitable access to the event.
Significance of results
The U.S. WHPCD Conference provides a virtual platform to disseminate high-quality science, honor both clinician and patient and caregiver experiences, and celebrate hospice and palliative care delivery during substantial local and global change across practice and policy domains. We remain committed to ensuring an internationally relevant, culturally diverse, and multidisciplinary and interprofessional agenda that will draw increased participation worldwide during future annual events.
Cryptosporidium parvum is a well-established cause of gastrointestinal illness in both humans and animals and often causes outbreaks at animal contact events, despite the availability of a code of practice that provides guidance on the safe management of these events. We describe a large C. parvum outbreak following a lamb-feeding event at a commercial farm in Wales in 2024, alongside findings from a cohort study to identify high-risk exposures. Sixty-seven cases were identified, 57 were laboratory-confirmed C. parvum, with similar genotypes. Environmental investigations found a lack of adherence to established guidance. The cohort study identified 168 individuals with cryptosporidiosis-like illness from 540 exposure questionnaires (distributed via email to 790 lead bookers). Cases were more likely to have had closer contact with lambs (odds ratio (OR) kissed lambs = 2.4, 95% confidence interval (95% CI): 1.2–4.8). A multivariable analysis found cases were more likely to be under 10 years (adjusted OR (aOR) = 4.5, 95% CI: 2.0–10.0) and have had visible faeces on their person (aOR = 3.6, 95% CI: 2.1–6.2). We provide evidence that close contact at lamb-feeding events presents an increased likelihood of illness, suggesting that farms should limit animal contact at these events and that revisions to established codes of practice may be necessary. Enhancing risk awareness among farmers and visitors is needed, particularly regarding children.
Pulmonary artery capacitance is a relatively novel measurement associated with adverse outcomes in pulmonary arterial hypertension. We sought to determine if preoperative indexed pulmonary artery capacitance was related to outcomes in paediatric heart transplant recipients, describe the changes in indexed pulmonary artery capacitance after transplantation, and compare its discriminatory ability to predict outcomes as compared to conventional predictors.
Methods:
This was a retrospective study of paediatric patients who underwent heart transplant at our centre from July 2014 to May 2022. Variables from preoperative and postoperative clinical, catheterisation, and echo evaluations were recorded. The primary composite outcome measure included postoperative mortality, postoperative length of stay in the top quartile, and/or evidence of end organ dysfunction.
Results:
Of the 23 patients included in the analysis, 11 met the composite outcome. There was no statistical difference between indexed pulmonary artery capacitance values in patients who met the composite outcome [1.8 ml/mmHg/m2 (interquartile 0.8, 2.4)] and those who did not [1.4 (interquartile 0.9, 1.7)], p = 0.17. There were no significant signs of post-operative right heart failure in either group. There was no significant difference between pre-transplant and post-transplant indexed pulmonary artery capacitance or indexed pulmonary vascular resistance.
Conclusions:
Preoperative pulmonary artery capacitance was not associated with our composite outcome in paediatric heart transplant recipients. It did not appear to be additive to pulmonary vascular resistance in paediatric heart transplant patients. Pulmonary vascular disease did not appear to drive outcomes in this group.
Historically, it has been proposed that functional neurological symptoms occur more frequently on the left side of the body due to a distinct body representation and emotional processing of the right hemisphere, yet objective imaging data to support this are lacking. We aimed to investigate whether patients with acute left-sided symptoms (right hemisphere) suspected of having a minor stroke are more likely to show negative diffusion-weighted imaging (DWI) compared to those with right-sided symptoms.
Methods:
Data are from the SpecTRA (Spectrometry for Transient Ischemic Attack Rapid Assessment) multicenter prospective cohort study conducted between 2013 and 2017. Patients with mild persistent unilateral hemiparesis and/or hemisensory symptoms (National Institute of Health Stroke Scale ≤ 3) and available DWI were included. The primary outcome was the proportion of patients with a negative DWI.
Results:
Of 1731 patients, 584 (30.8%) were included. Of these, 310 (53.1%) patients presented with left-sided symptoms and 274 (46.9%) with right-sided symptoms. Overall, 214 (36.6%) patients had a negative DWI, 126 (58.9%) with left-sided symptoms and 88 (41.1%) with right-sided symptoms: risk ratio (RR) 1.27 (95% CI = 1.02–1.57). Left-sided hemiparesis was associated with negative DWI (RR 1.42 [95% CI = 1.08–1.87]), while left-sided hemisensory symptoms were not (RR 1.11 [95% CI = 0.87–1.41]). There was no effect modification by age or sex on this association (Pinteraction 0.787 and 0.057, respectively).
Conclusions:
Unilateral left-sided neurological symptoms were more frequently associated with negative DWI compared to right-sided symptoms in suspected minor stroke patients. This observation is exploratory, as the final diagnosis in DWI-negative cases was not established.
Recent changes to US research funding are having far-reaching consequences that imperil the integrity of science and the provision of care to vulnerable populations. Resisting these changes, the BJPsych Portfolio reaffirms its commitment to publishing mental science and advancing psychiatric knowledge that improves the mental health of one and all.
Posttraumatic stress disorder (PTSD) has been associated with advanced epigenetic age cross-sectionally, but the association between these variables over time is unclear. This study conducted meta-analyses to test whether new-onset PTSD diagnosis and changes in PTSD symptom severity over time were associated with changes in two metrics of epigenetic aging over two time points.
Methods
We conducted meta-analyses of the association between change in PTSD diagnosis and symptom severity and change in epigenetic age acceleration/deceleration (age-adjusted DNA methylation age residuals as per the Horvath and GrimAge metrics) using data from 7 military and civilian cohorts participating in the Psychiatric Genomics Consortium PTSD Epigenetics Workgroup (total N = 1,367).
Results
Meta-analysis revealed that the interaction between Time 1 (T1) Horvath age residuals and new-onset PTSD over time was significantly associated with Horvath age residuals at T2 (meta β = 0.16, meta p = 0.02, p-adj = 0.03). The interaction between T1 Horvath age residuals and changes in PTSD symptom severity over time was significantly related to Horvath age residuals at T2 (meta β = 0.24, meta p = 0.05). No associations were observed for GrimAge residuals.
Conclusions
Results indicated that individuals who developed new-onset PTSD or showed increased PTSD symptom severity over time evidenced greater epigenetic age acceleration at follow-up than would be expected based on baseline age acceleration. This suggests that PTSD may accelerate biological aging over time and highlights the need for intervention studies to determine if PTSD treatment has a beneficial effect on the aging methylome.
Objectives/Goals: Magnetic resonance imaging (MRI) reports are stored as unstructured text in the electronic health record (EHR), rendering the data inaccessible. Large language models (LLM) are a new tool for analyzing and generating unstructured text. We aimed to evaluate how well an LLM extracts data from MRI reports compared to manually abstracted data. Methods/Study Population: The University of California, San Francisco has deployed a HIPAA-compliant internal LLM tool utilizing GPT-4 technology and approved for PHI use. We developed a detailed prompt instructing the LLM to extract data elements from prostate MRI reports and to output the results in a structured, computer-readable format. A data pipeline was built using the OpenAI Application Programming Interface (API) to automatically extract distinct data elements from the MRI report that are important in prostate cancer care. Each prompt was executed five times and data were compared with the modal responses to determine variability of responses. Accuracy was also assessed. Results/Anticipated Results: Across 424 prostate MRI reports, GPT-4 response accuracy was consistently above 95% for most parameters. Individual field accuracies were 98.3% (96.3–99.3%) for PSA density, 97.4% (95.4–98.7%) for extracapsular extension, 98.1% (96.3–99.2%) for TNM Stage, had an overall median of 98.1% (96.3–99.2%), a mean of 97.2% (95.2–98.3%), and a range of 99.8% (98.7–100.0%) to 87.7% (84.2–90.7%). Response variability over five repeated runs ranged from 0.14% to 3.61%, differed based on the data element extracted (p Discussion/Significance of Impact: GPT-4 was highly accurate in extracting data points from prostate cancer MRI reports with low upfront programming requirements. This represents an effective tool to expedite medical data extraction for clinical and research use cases.
Objectives/Goals: Early childhood obesity is a major concern for Latin American children in the U.S., with gut barrier dysfunction as a key risk factor. Diet plays a role in gut development, but few studies have focused on Latin American infants. Our objective is to identify culturally relevant introductory foods that promote in vitro gut barrier development and function. Methods/Study Population: Pooled human milk (2.5 mL) from 6-month postpartum Hispanic mothers was combined with fruit and vegetable baby food products (2.5 g) and subjected to a 3-phase in vitro digestion system that simulates oral, gastric, and intestinal digestion. Digesta products were then anaerobically fermented for 24-hours using human stool inoculum, centrifuged, and filter sterilized. Intestinal epithelial cells (Caco-2, ATCC) were grown to confluence on 0.4 μm polystyrene transwell inserts using a DMEM + 10% FBS medium and allowed to differentiate for 21-days. Highly differentiated monolayers were treated with a 1:4 dilution of fermenta with medium in triplicate. The cell experiment was conducted twice. Cell layer integrity was measured using transepithelial electrical resistance (TEER) 24- and 48-hours after treatment. Results/Anticipated Results: Dietary intake data from the What We Eat in America database indicated that the top 3 fruit and vegetable exposures for infants with Mexican or Hispanic ethnicity were banana, apple, and carrot. Commercial baby food purees of these fruits and vegetables, in addition to baby foods with blueberry and spinach (Natural for Baby, Gerber Products Company) were acquired for digestion and fermentation experiments. Caco-2 cell experiments with these foods are ongoing. We expect Caco-2 monolayer incubated with fermenta from human milk and fruit or vegetables will have greater TEER values due to increased integrity of the cell layer as compared to those with breast milk alone. We also expect that exposure to fruit and vegetable fermenta will increase gene expression of tight junctions compared to exposure to media and human milk. Discussion/Significance of Impact: Using an in vitro digestion and fermentation system coupled with cell culture studies, we are identifying cellular mechanisms that link individual fruits and vegetables to gut barrier function. This will support translational work focused on mitigating obesity development in vulnerable populations.
The Early Minimally Invasive Removal of Intracerebral Hemorrhage (ENRICH) trial demonstrated that minimally invasive surgery to treat spontaneous lobar intracerebral hemorrhage (ICH) improved functional outcomes. We aimed to explore current management trends for spontaneous lobar ICH in Canada to assess practice patterns and determine whether further randomized controlled trials are needed to clarify the role of surgical intervention.
Methods:
Neurologists, neurosurgeons, physiatrists and trainees in these specialties were invited to complete a 16-question survey exploring three areas: (1) current management for spontaneous lobar ICH at their institution, (2) perceived influence of ENRICH on their practice and (3) perceived need for additional clinical trial data. Standard descriptive statistics were used to report categorical variables. The χ2 test was used to compare responses across specialties and career stages.
Results:
The survey was sent to 433 physicians, and 101 (23.3%) responded. Sixty-eight percent of participants reported that prior to publication of the ENRICH trial, spontaneous lobar ICH was primarily managed conservatively, with surgery reserved for life-threatening situations. Forty-three percent of participants did not foresee a significant increase in surgical intervention at their institution. Of neurosurgical respondents, 33% remained hesitant to offer surgical intervention beyond lifesaving operations. Only 5% reported routinely using specifically designed technologies to evacuate ICH. Seventy percent reported that another randomized controlled trial comparing nonsurgical to surgical management for spontaneous lobar ICH is needed.
Conclusions:
There is significant practice variability in the management of spontaneous lobar ICH across Canadian institutions, stressing the need for additional clinical trial data to determine the role of surgical intervention.
Ultrasound-guided wire localisation may improve intra-operative identification and outcomes of non-palpable cervical lymphadenopathy in a previously treated neck. We undertook a literature search and present our case series to determine the safety and efficacy of ultrasound-guided wire localisation.
Methods
A search of databases up to 29 April 2024 was performed. At our tertiary centre, ultrasound-guided wire localisation was utilised for 20 patients with cervical lymphadenopathy between February 2021 and April 2024.
Results
Seventeen studies with a combined total of 92 patients were identified, with one complication reported. Within our case series, all 20 patients had accurate lesion localisation using ultrasound-guided wire localisation and none required repeat operations.
Conclusion
Ultrasound-guided wire localisation is a safe and cost-effective technique for lesions in an otherwise difficult area to operate, providing confidence to the multidisciplinary team, particularly where histopathology indicates benignity. Surgical outcomes do not appear worse than outcomes without ultrasound-guided wire localisation. We advocate its use provided appropriate patient selection is considered.
This paper analyzes playful activities within protests against the 2020 Tokyo Olympics. It examines their relationship with contested urban space and the legacy of Heiseiera social movements in Japan as well as other anti-Olympics activism. It argues that these practices represent a creative, cultural dimension of the opposition to 2020.
This paper examines protests that have taken place against the 2020 Tokyo Olympics, focusing on the activities of one group and analyzing them as a form of “play” and cultural creativity contesting urban spaces. In this way, the paper highlights an aspect of the protests that links to earlier social movements in Japan as well as a style of protest that transcends the negativity often associated with anti-Olympics activism.
Almost every one or two weeks a large envelope arrives in my mailbox. Opening it up invariably reveals a flier, newsletter or newspaper, often accompanied by a handwritten note with a tailored message. At the risk of sounding facetious, only my mobile phone provider is as punctual and frequent. But the deliveries are not from any commercial service. They are from a prisoner support group.
The proscription of organisations has long been a central feature of legal regimes aimed at the suppression of terrorism. Australia is no exception. Going back many decades, the Commonwealth government has sought to meet the threat of political violence through the proscription of related organisations. In the wake of the September 11 terrorist strikes against New York and Washington, renewed efforts were made for the proscription of organisations in many national jurisdictions (for example, the United Kingdom, United States and Canada) as well as at the international level (for example, through the United Nations and the European Union.
In Australia, the Commonwealth looked directly to the justifications offered by the United Kingdom’s Lord Lloyd of Berwick and Paul Wilkinson just a few years before. In their major Inquiry into Legislation Against Terrorism, Lord Lloyd and Wilkinson presented three principal rationales to explain the role of proscription in the prevention of terrorism: ease of proof; providing a basis for the criminalisation of fundraising and other activities of terrorist groups; and as a clear symbol of ‘public revulsion and reassurance that severe measures [are] being taken’.
Williams v Commonwealth of Australia is a landmark decision of the High Court on the scope of federal executive power in s 61 of the Constitution. The decision is also important for the interpretive methodology adopted by the Court. Notably, each judge based their understanding of s 61 upon federal readings of the Constitution. This methodology raises fresh questions about how the Constitution is to be interpreted, and whether Williams marks a break from orthodox understandings of that task. This article assesses the significance of Williams for constitutional interpretation in Australia, and whether it lays the foundation for a more robust protection of state interests by the High Court.
Medicines routinely funded for use in Wales undergo health technology appraisal by the All Wales Medicines Strategy Group (AWMSG) or the National Institute for Health and Care Excellence (NICE). This includes pediatric license extensions (PLE) notwithstanding any existing advice in adults. A review of the PLE process was conducted with the aim of providing faster access to children’s medicines in Wales.
Methods
Data were collected for PLE appraisals of medicines previously approved for adults by the AWMSG or NICE that subsequently went through the original PLE process between January 2010 and December 2020, or a simplified PLE process between January 2021 and March 2023. Data were analyzed using descriptive statistics and a two-tailed t-test (unequal variance) to test the null hypothesis that the difference between the two means was zero. An alpha of less than 0.05 was considered significant. Feedback was obtained from relevant stakeholders including the Association of the British Pharmaceutical Industry (Wales) and the Royal College of Paediatrics and Child Health.
Results
The AWMSG issued positive recommendations for all PLE appraisals included in the data collected, and these were endorsed by the Welsh Government. Appraisals that went through the original PLE process (n=56) took a mean 229.8 days (standard deviation 55.6), whereas those that went through the simplified PLE process (n=15) took a mean 102.6 days (standard deviation 48.1; p < 0.0001). The rapid access to children’s medicines was welcomed by the Association of the British Pharmaceutical Industry and the Royal College of Paediatrics and Child Health.
Conclusions
Review of the 2020 and 2023 PLE processes facilitated faster access to clinically effective and cost-effective medicines for children in Wales. In March 2023, the AWMSG and the Welsh Government reviewed these results and agreed that because all PLE medicines were approved for use within Wales irrespective of the process used, the AWMSG would no longer be required to routinely appraise PLEs.
An Australian Offensive Cyberspace Operations (OCO) capability has emerged as an important sub-component of national power. While significant academic literature exists concerning OCO’s place within the international law of armed conflict, and international law in general, literature regarding domestic law is scarce. Nevertheless, an understanding of the domestic law governing the Australian Defence Force’s (ADF’s) authority to conduct OCO is necessary as the gap in the research potentially exposes the Government and individuals to legal risks that are not well understood. The aim of this article is to analyse the proprietary and constitutional implications of ADF OCO to inspire further research at a time when the Comprehensive review of the legal framework governing the National Intelligence Community is underway. The qualitative research analyses statutory and case law authorities to argue that Australian proprietary and constitutional law creates important implications for ADF OCO. The analysis suggests that these implications oblige the Commonwealth to be careful in balancing its legislative and executive power to provide the ADF with the legal authority to conduct OCO. The research finds that OCO impinges upon the proprietary rights of others, requiring legal authority which, if created under statute, generates an obligation to compensate proprietors under just terms. However, if the authority arises under the executive power, then the obligation to compensate may not apply. Further, such executive powers may exist under a royal war prerogative. As a corollary, we suggest that in an escalated conflict environment, the ADF may be able to conduct OCO without any legislative amendments to the criminal law although express immunities would be preferred.
