Network analysis of trauma-related mental health comorbidities under continuous traumatic stress: a comparative study of South African and Ukrainian adolescents

BackgroundAdolescents living under conditions of continuous traumatic stress (CTS) are exposed to ongoing, persistent, unpredictable threats that differ from past discrete traumatic events and are associated with high levels of CTS symptoms, posttraumatic stress disorder (PTSD), depression, and anxiety. Despite growing evidence that CTS functions as a risk factor for trauma-related disorders, little is known about how specific CTS symptoms are embedded within broader psychopathology networks across diverse contexts of chronic violence.AimThis study applied item-level network analysis to examine the structural role of individual CTS symptoms within PTSD, depression, and anxiety symptom networks among adolescents exposed to CTS in South Africa (n = 600) and Ukraine (n = 485).MethodAdolescents (aged 12 to 18 years) completed standardised measures of CTS, PTSD, depression, and anxiety symptoms. Item-level network models were used to examine within- and cross-domain symptom associations, identify central and bridging CTS symptoms, assess their predictive value for overall symptom severity, and test network invariance across countries.ResultsIn both samples, strong within-domain clustering was observed alongside robust cross-domain connections linking CTS symptoms with PTSD, depression, and anxiety symptoms. In Ukraine, CTS symptoms were represented by symptoms reflecting loss of meaning, intense fear or horror, and episodes of rage, while in South Africa, CTS symptoms were represented by difficulty controlling emotions, feelings of betrayal, and perceived life threat. The findings also suggest that CTS symptoms were more tightly interconnected and more evenly distributed across PTSD, depression, and anxiety symptoms in the Ukrainian sample, whereas the South African sample demonstrated a broader and more diffuse symptom pattern, with anxiety-related symptoms appearing to be more prominently expressed.ConclusionFindings suggest that CTS symptoms may potentially operate as a transdiagnostic process – cutting across, and contributing to shared variance in PTSD, depression, and anxiety symptoms – among adolescents exposed to ongoing violence. Interventions targeting core CTS bridge symptoms may reduce comorbidity and improve mental health outcomes in chronically threatened youth across diverse conflict settings.

Which classroom anxiety experience should teachers target first? A network-simulation study of foreign language classroom anxiety and enjoyment

BackgroundForeign language classroom anxiety and enjoyment are moderately negatively related, but this relationship has been examined almost entirely at the total score level, and to our knowledge, no published study has asked which specific anxiety experiences are most closely coupled to enjoyment.MethodsUsing item-level psychological network analysis and the GGMNIRA simulated node-manipulation framework, we estimated the joint network of eight anxiety items and nine enjoyment items in 3,957 Chinese non-English-major college students and simulated the alleviation of each anxiety node in turn.ResultsRank-based stability was high (case-dropping correlation stability coefficient ≥ 0.75 for EI, BEI, and the KL rankings). The highest expected influence nodes were shared jokes and topics and teacher support; among anxiety items, panic without preparation speaking ranked highest. The simulations applied two complementary criteria that answer different questions: panic without preparation produced the largest distributional reconfiguration of the enjoyment construct, whereas alleviating nervousness when speaking predicted the largest signed enjoyment gain, the largest model-implied gain among the eight anxiety items. The highest bridge-centrality anxiety node showed negligible simulated effects.ConclusionsSpeaking-related anxiety, particularly the fear of speaking without preparation, is the anxiety experience most closely coupled to enjoyment. Simulated conditioning offers a principled, model-implied complement to centrality when researchers generate hypotheses about which anxiety experiences classroom practice might target first.

Longitudinal reference data for the German D-AMI in major depression and healthy controls: implications for future ECT research

BackgroundElectroconvulsive therapy (ECT) is an effective treatment for major depressive disorder (MDD). Retrograde autobiographical memory impairment is considered one of the clinically relevant adverse effects of ECT; however, no validated German instrument is available to assess autobiographical memory. Although longitudinal autobiographical memory data are available from previous studies of patients with depression not receiving ECT, corresponding reference data for the German-language AMI-SF have not been established. This study evaluated the feasibility and interrater reliability of the German Autobiographical Memory Interview-Short Form (D-AMI) and established longitudinal reference data in MDD and healthy controls.MethodsSixty participants (30 patients with MDD and 30 healthy controls), none of whom received ECT during the observation period, completed the D-AMI at baseline and after a 6-week interval. Feasibility was assessed by completion rates and missing data. Interrater reliability was evaluated in a subset (n = 10) using a two-way random-effects intraclass correlation coefficient (ICC). Longitudinal performance was quantified using D-AMI score change and its baseline-normalized expression, retrieval consistency. Associations between autobiographical memory measures and depressive symptom severity were explored.ResultsThe D-AMI demonstrated a 100% completion rate with no missing data. Interrater reliability was ICC[2,1] = 0.71 (95% CI = 0.17-0.92), indicating considerable uncertainty. The magnitude of longitudinal inconsistency was greater in patients with MDD than in healthy controls, although this between-group difference should be interpreted cautiously because study site and rater were confounded with group.ConclusionsThe D-AMI is a feasible instrument for assessing autobiographical memory in German-speaking populations, while the preliminary interrater reliability estimate requires confirmation in larger samples. The observed magnitude of longitudinal D-AMI inconsistency provides reference information for repeated assessments in the absence of ECT; however, the between-group difference requires cautious interpretation because group, site, and rater effects could not be separated. These findings provide the first longitudinal reference data for the German D-AMI and indicate that changes in autobiographical memory scores should not automatically be interpreted as evidence of ECT-related memory impairment. Rather, such changes should be considered in the context of test-retest variability and retrieval consistency.

Efficacy of stem cell-derived extracellular vesicles in animal models of autism spectrum disorder: a systematic review and meta-analysis

BackgroundAutism spectrum disorder (ASD) is a complicated neurodevelopmental condition that currently lacks a targeted therapy. Although stem cell-derived extracellular vesicles (EVs) represent a potential therapeutic approach for neurological disorders, their efficacy in ASD remains unclear. The objective of this study was to investigate the efficacy of stem cell-derived EVs on autistic-like behaviors in animal models of ASD and to explore the underlying mechanisms.MethodsRelevant studies published up to April 20, 2026 were searched across five databases. Data were pooled using Review Manager 5.4. Outcome measures included behavioral tests and inflammatory cytokine levels.ResultsOut of 1,165 initially retrieved articles, five animal studies met the inclusion criteria. Pooled analyses demonstrated that EV treatment improved autistic-like behaviors in the self-grooming test, three-chamber social interaction test, and marble burying test, and decreased levels of proinflammatory cytokines IL-6 and IL-1β (all P < 0.05). No notable enhancements were observed for the open field test, Morris Water Maze, TNF-α or IL-10 (all P > 0.05).ConclusionStem cell-derived EV therapy may improve repetitive behaviors and social deficits in ASD animal models, with observed associations with reduced IL-6 and IL-1β levels. These preclinical findings suggest promising translational potential of EV-based therapy for ASD.Systematic Review Registrationhttps://osf.io/c78xm, identifier 10.17605/OSF.IO/C78XM.

Rethinking childhood-onset schizophrenia: neurodevelopmental comorbidities shape the psychopathological profile

ObjectivesChildhood-onset schizophrenia (COS), defined by the onset of psychotic symptoms before the age of 13 years, is a rare and severe form of schizophrenia. Despite growing interest, little is known about how neurodevelopmental comorbidities shape its clinical presentation. This study aimed to examine whether COS with comorbid neurodevelopmental disorders differs in psychopathological profile from COS with psychiatric comorbidities and from COS without comorbidities.MethodsSixty-one children diagnosed with COS and evaluated at symptom onset in a specialized early psychosis service were included and classified into three subgroups: COS with neurodevelopmental comorbidities, COS with psychiatric comorbidities, and COS without comorbidities. Psychopathological dimensions were assessed using the Kiddie Schedule for Affective Disorders and Schizophrenia for School-Aged Children – Present and Lifetime Version and the Structured Interview for Psychosis-Risk Syndromes and the Scale of Prodromal Symptoms (SIPS/SOPS). Group differences were examined using MANOVA and mixed-design repeated-measures ANOVA, repeated with IQ as a covariate, with False Discovery Rate correction across all SIPS measures. A secondary analysis separated intellectual disability from autism spectrum disorder and/or attention-deficit/hyperactivity disorder.ResultsChildren with COS and neurodevelopmental comorbidities showed an earlier age at onset, lower IQ, greater bizarre thinking and less social anhedonia. In contrast, COS with psychiatric comorbidity and COS without comorbidities exhibited largely overlapping profiles, marked by greater severity of negative symptoms and more organized thought processes. Within the neurodevelopmental group, the symptom pattern did not appear to be driven by specific diagnoses.ConclusionsThese preliminary findings are consistent with variation in the configuration of psychopathological features within COS along a continuum, and highlight the relevance of neurodevelopmental trajectories in shaping symptom expression. Accounting for neurodevelopmental comorbidities may be crucial for improving early diagnostic characterization and informing targeted therapeutic strategies in pediatric schizophrenia.

Development of a messenger RNA therapy for schizophrenia

Few gene-disease associations identified by human genetic studies lead to new drugs that advance to first-in-human trials. Schizophrenia exemplifies this translational gap: thousands of gene-disease associations have been reported, but antipsychotics act via mechanisms introduced in the 1950s. To close the gap, clinical research strategies are needed that generalize across genes and diseases.

Reporter’s Notebook: Cell and Gene Therapy’s Success Lies Beyond the Bespoke (Part 1)

PHOENIX, AZ — In my fifth year attending the Cell and Gene Meeting on the Mesa, I’ve seen a handful of trends trudge forward, stop dead in their tracks, and, in some cases, reverse course. 

Two years ago, cell and gene therapy (CGT) seemed like an untapped oil reserve waiting to power a new medical era. Casgevy, the first approved CRISPR medicine, had launched a new commercial era for gene editing, while CGT poster child CAR T-cell therapy was just one month shy of its seventh anniversary on the market, with seven approved therapies to match. All seven CAR T-cell therapies, along with Casgevy, were autologous.

An entire cell therapy industry formed around the autologous model, spawning and attracting a supersaturation of contract development and manufacturing organizations (CDMOs). To get a piece of the cell therapy commercialization pie, some CDMOs took up niches in preclinical development or clinical trial production at the requisite Current Good Manufacturing Practice (cGMP) standards. Other CDMOs specialized in the digital infrastructure needed to track cells on their “vein-to-vein” journey, and a select few even ventured into the realm of developing instruments for customers to bring production in-house. 

Few cell manufacturing concepts attracted as much attention as Cellares, touting a new generation of CDMOs—an automated “Industry 4.0” CDMO model dubbed “intelligent development and manufacturing organization” (IDMO). Co-founder and CEO Fabian Gerlinghaus preached that the platform would be an autologous cell therapy “kingmaker.” That claim didn’t seem overconfident after Cellares bolstered its position in April 2024, signing a deal worth up to $380 million with Bristol Myers Squibb (BMS) to manufacture selected CAR T-cell therapies globally. 

On the genetic medicine side, a few dozen gene therapies had been approved, and in vivo gene editing appeared imminent. Novartis’s Zolgensma, the standout, had generated roughly $1.2–1.4 billion annually since 2021 and had treated several thousand patients globally, while Sarepta’s Elevidys ramped much faster, from $200 million in 2023 to $821 million in 2024 and $899 million in 2025. 

However, between 2024 and 2026, there have been major setbacks across CGT. Elevidys was poised to surpass Zolgensma, but safety concerns and label restrictions halted its growth in 2025 after three Sarepta gene therapy-induced acute liver failure deaths. In August 2026, BMS walked away from the manufacturing deal, claiming Cellares’s offering failed to meet “the necessary requirements to make commercial Breyanzi.” 

Yet the tone at the 2026 Cell and Gene Meeting on the Mesa was anything but woeful or beaten down. Instead of personalizing every CGT, commercialization is pushing developers to broaden the patient pool for each program. These caught my eye at the Alliance for Regenerative Medicine (ARM) annual meeting.

Searching for the sweet spot 

Jodi Cook, PhD, CEO of Skylark Bio, is a gene therapy veteran. She has been to all fifteen Cell and Gene Therapy Meeting on the Mesa conferences and told Inside Precision Medicine a pragmatic field is emerging. “The industry exploded on new money for a while,” Cook said. “Money was flowing everywhere, not just into gene therapy, and then it stopped. Now, we’re back to being mission-focused with sound business fundamentals to drive products forward.” 

Instead of raising successive rounds around incremental milestones, Cook believes that companies need enough capital to reach the clinic and compelling data to unlock the next investment. “Now, it’s more like you raise one large round of funding to get into first-in-human trials,” Cook said. “That makes it increasingly important to establish the commercial opportunity much earlier.” 

According to Cook, Skylark, a clinical-stage gene therapy company targeting inherited hearing loss and CNS disorders, prioritized commercialization and de-risking from the outset, advancing preclinical studies from mice to NHPs and then minipigs, whose inner ears closely approximate human size. “I tell my investors that we’ve de-risked everything we can externally,” said Cook. “Now the risk that’s left is execution, and I can control that.” Cook added, “All of the preclinical work and science line up. If you get it into the right cells, which we are, that should, over time, improve these children’s hearing, we did everything we could.” 

Skylark’s lead program illustrates one way to balance precision with scale. It targets GJB2-associated hearing loss, which accounts for 15% to 30% of all inherited hearing impairment. But rather than developing treatments for individual mutations, Skylark delivers a functional copy of the entire GJB2 gene. “There are multiple different mutations within the GJB2 gene,” Cook said. “We’re replacing the whole gene, so we don’t have to slice and dice to personalize it to you.” 

Skylark is applying the “doing more with less” approach throughout the pipeline. While each program requires a tailored payload, promoter, and regulatory elements, Cook is pushing for Skylark to get as close as possible to a “plug-and-play” model, reusing its capsid, manufacturing process, and much of its analytical infrastructure. That reuse could compress development timelines: what took three and a half years for Skylark’s first indication took about 18 months for its second. 

The goal, Cook said, is to finally make good on a longstanding gene therapy promise: “The business model can work if you can reuse or reapply the platform instead of doing something completely different for every individual.”

The “other kind” of optogenetics 

One striking, out-of-the-box example of broadening a single gene therapy’s clinical applicability came from Nanoscope Therapeutics’ gene therapy solution to restore vision. Inherited retinal dystrophies (IRDs) are a diverse group of progressive genetic eye disorders characterized by the dysfunction and degeneration of photoreceptors (rods and cones) and the retinal pigment epithelium (RPE). Nanoscope’s strategy, however, has nothing to do with correcting the underlying congenital mutations that cause blindness. “If you don’t have functional photoreceptors, it may not matter which disease caused it, and there are dozens of them,” Samarendra Mohanty, PhD, Nanoscope’s president, CSO, and co-founder, said to Inside Precision Medicine. 

Nanoscope’s MOGENRY (sonpiretigene isteparvovec) delivers an engineered chimeric multi-characteristic opsin (MCO) to surviving bipolar cells that critically transduce light-gated photoreceptor activity. COO Paul Hallen said, “We’re essentially hijacking the bipolar cells to make them de facto photoreceptors. If your photoreceptors are dying and your bipolar cells remain intact, and there are roughly 10 million of them, that creates an opportunity.”

To do so, Nanoscope doesn’t insert functional human opsins but rather a synthesized, Frankenstein-esque opsin that is far from naturally occurring or human. “There is no single molecule or opsin in nature that is broadband-sensitive, fast, and highly sensitive,” said Jared Stephens, Nanoscope’s vice president of strategy and business development. 

The MCO combines components derived from two algae and a sea anemone to respond rapidly across ordinary ambient light, making it suitable for restoring real-world vision without blur. “Here, we’re expressing a protein that is not only non-mammalian but derived from three different non-mammalian organisms,” Mohanty added. “This may be the most synthetic protein or gene sequence ever expressed in a human.” 

Nanoscope and other vision-loss companies call their tech optogenetics, which was intriguing after the 2026 Nobel Prize in Physiology or Medicine announcement. Mohanty mentioned Nanoscope’s optogenetic approach but, unprovoked, clarified the differences between their MCO and the work of newly minted Nobel laureates Karl Deisseroth, MD, PhD, Peter Hegemann, PhD, and Georg Nagel, PhD. 

“In optogenetics research, if you’re trying to probe 100 different types of cells in the brain, the goal has primarily been to stimulate each with a single wavelength of light,” Mohanty said. “You want zero crosstalk: blue responds to blue, green to green, red to red, etc. Our goal was the opposite.” 

Regardless, regulators are seeing the broad potential of Nanoscope’s MCOs. The PMDA—Japan’s FDA equivalent—recently accepted MOGENRY for priority review for IRDs, supported by data in retinitis pigmentosa and Stargardt disease.

But what about gene editing? 

For Allen Reine, MD, CEO of Prime Medicine, the key to CGT is to nail down differentiated products and platforms. “I don’t think we want to be another company simply doing another PCSK9 therapy,” said Reine. “Are we solving a problem that others can’t by doing that? Probably not. The question is, where is prime editing differentiated, and where is it a unique approach to solving a problem?” 

The answer for Reine lies in addressing an unmet need with a differentiated therapy/approach that will make a meaningful difference to patients. “We have to check those boxes,” said Reine, who was an investor for 15 years before coming onto the operational side. “If all of those things are true, then there is likely a commercial opportunity. Then what we’re doing is good for patients and good for investors. When those two things align, that’s a great place for a company to be.” 

Reine thinks their Wilson’s disease program qualifies, and on day 1 of the conference, Prime Medicine announced the first dose of PM577a, an investigational in vivo prime editor for H1069Q-mutated Wilson disease, in its global Phase I/II study. 

Prime’s Alpha-1 Antitrypsin Deficiency (AATD) program trails close behind. Even though it’s a competitive space, Prime’s AATD program meets Reine’s criteria, who explained, “With alpha-1, it’s a competitive space, in part because the vast majority—95%, maybe 98%—of patients have one mutation. That makes it a very attractive target for gene-editing and RNA-editing therapies.” 

Reine expects clinical results for the Wilson and AATD liver programs in 2027, which will prove useful for advancing programs targeting other cell types. Prime has shown promising preclinical data in various tissues and indications, including the lung and cystic fibrosis, which Reine believes is highly translatable and profitable. “I strongly believe we can ultimately show that there are good business models behind these therapies in many cases,” said Reine. “That’s where we’re going to see important inflection points. To me, that means more dollars flowing into the space, more dollars being spent on programs and drugs that ultimately get to patients, and more patients who can potentially be cured of disease.”

Automated autologous cell therapies  

Though disappointed in BMS’ withdrawal from Cellares’ manufacturing agreement, Gerlinghaus believes the company will stay on course. “Losing BMS was a setback, but BMS does not define the company,” Gerlinghaus told Inside Precision Medicine. Two weeks before the termination and reduction in force became public, he was visiting customers nationwide. Their response, he said, ranged from “We’re with you. This doesn’t change things for us” to asking whether Cellares could accelerate existing projects or take on additional trials. “One decision from one customer doesn’t change the vote of confidence we’ve gotten from a dozen other customers in the industry.” 

Cellares has since leaned harder into a portfolio strategy, more than doubling its customer base since the beginning of the year and aiming to build a portfolio of 30 to 40 active autologous ex vivo programs. “I don’t see us slowing down. I actually see us accelerating,” Gerlinghaus said. The main consequence of losing BMS, he argued, is timing: “It’ll just take about a year longer to get to commercial manufacturing than it otherwise would have.” 

There are successes for Cellares to report, including being one of eight companies picked for the FDA PreCheck program, which received over eighty applications. Similar to TSA PreCheck, the selection provides accelerated facility inspections for new domestic human drug and biological product manufacturing facilities ahead of commercial launch. Cellares was chosen alongside Eli Lilly, Regeneron, Amneal, Fujifilm Biotechnologies, Kriya Therapeutics, and Kyowa Kirin. 

The setback also tempered some of Gerlinghaus’ swagger. Asked whether he still stood by his previous description of Cellares as a potential “kingmaker,” Gerlinghaus replied: “As I get older, I get more humble.” After years of seemingly uninterrupted milestones, he acknowledged, “Now we’ve had a setback. But show me one company that never had a setback.” 

No company, field, product, or market has ever grown without setbacks. The key is to stay afloat until the stars align for a breakthrough. 

 

In Part 2 of this two-part series, Tim Hunt, CEO of the Alliance for Regenerative Medicine (ARM), and Karim Mikhail, the new director at the Center for Biologics Evaluation and Research (CBER), explain existing and developing frameworks for growing a sustainable cell and gene therapy industry.

Experts’ Needs Assessment and Evaluation of Mobile Apps for Children of Parents With Mental Illness: Mixed Methods Study

Background: Children of parents with mental health illness (COPMI) have the right to receive preventive interventions to avoid developing their own mental health and socioeconomic problems. However, access to interventions varies widely within health care and social services depending on their geographical location in Sweden. In this regard, mobile health (mHealth) interventions for COPMI provide a pathway for more equitable and sustainable preventive support. Objective: This project aims to (1) map and assess the quality of available mHealth apps relevant to COPMI; (2) investigate experts’ perceptions of COPMI needs for digital health solutions (particularly mHealth) by consulting and collaborating with an interdisciplinary reference group (scholars, child rights organizations, and IT professionals); and (3) explore the prerequisites for development, implementation, and sustainable access to future digital solutions for COPMI. Methods: We collaborated with a reference group through a series of meetings and workshops, identifying and assessing the quality of 9 free, highly ranked apps (ie, using the well-known Mobile App Rating Scale [MARS]). All the workshop sessions were recorded and transcribed for further qualitative analysis, allowing us to document and derive our main findings. Results: Three out of 9 apps received high scores across the MARS dimensions of aesthetics, perceived functionality, information, and engagement in the expert heuristic evaluation using recorded demonstrations of the apps, indicating a significant lack of high-quality apps relevant to COPMI. Further findings were derived, such as the experts’ preference for more general apps that are not specifically targeted to COPMI, as these could promote self-identification and reduce stigmatization. Regarding the third aim, the results showed that it was important to find an app that protected users’ privacy by allowing anonymous access to digital support and that mobile apps should be complemented (or replaced) by web-based applications to improve accessibility for children who may not be allowed to download apps without parental permission. Conclusions: The sustainability of digital solutions (web applications or mobile apps) for COPMI is the biggest challenge for future developments. Long-term impact requires stable funding, continuous maintenance, and partnering with established organizations that already possess the infrastructure, expertise, and reach necessary to provide ongoing support. To address the limitations in the study design and deployment issues, it is important to actively involve children through participatory and co-creational approaches when designing and developing mHealth solutions. Also, future evaluations should include privacy and data security assessments such as app permissions, privacy-policy presence, and third-party sharing.
