“You have to wait for a diagnosis first”: Barriers to preventive mental health support and early interventions for children and young people in Sweden

by Karin Törnbom, Dominique Hange, Eva-Lisa Petersson, Irene Svenningsson

Background

Despite increasing attention to youth mental health, children and adolescents in Sweden experience fragmented, inequitable care with regional variation. Delays in diagnosis, limited preventive interventions, and poor inter-sectoral collaboration contribute to significant unmet needs. This study investigates system-level challenges and stakeholder perspectives on opportunities to enhance care pathways.

Methods

We conducted a qualitative study in the Västra Götaland region, Sweden. Fourteen purposively selected participants – including senior executives, healthcare professionals, and parents took part in semi-structured interviews. We used systematic text condensation, according to Malterud, and the four steps involved in this method for analysing the interviews.

Results

A central theme across interviews was the requirement for a formal diagnosis before children can access mental health support, particularly in school and primary care settings. Participants described this as a major barrier that delays early intervention and leaves children and young people with complex or atypical presentations without adequate support. Primary care professionals reported increasing mental health caseloads without corresponding increases in staffing or funding, limiting preventive work. Child and adolescent psychiatry (BUP) was described as overwhelmed, with long waiting times and limited continuity of care. A care manager within primary care was proposed as a way to help families navigate fragmented services and improve collaboration, although participants emphasised that such a role would need to be part of broader structural reform.

Conclusions

Our findings highlight persistent systemic issues in mental health care for children and young people, including inequitable access, insufficient prevention, and fragmented collaboration across sectors. Strengthening primary prevention, reallocating resources to primary and school-based mental health care and implementing well-defined care coordination roles within broader restructuring may improve continuity and equity in service delivery. Comprehensive policy reform is needed to support person-centred, integrated care pathways for children and young people with mental health needs.

by Agatha Ribeiro Kalthof, Nikolas Dresch Ferreira, Caio Mateus Silva, Iuri Cordeiro Valadão, Iguaracy Pinheiro de Sousa, Ester Riserio Matos Bertoldi, Vanessa Morais Lima, Lauro Thiago Turaca, Ana Beatriz Ruiz Afonso Barbosa, Miriam Helena Fonseca-Alaniz, Jean-Paul Concordet, Elida Adalgisa Neri, Jose E. Krieger

Generating mature human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) remains a major obstacle to accurate disease modeling and cardiac repair. As the transcription factor Irx3 is a key determinant of ventricular conduction system fate in mice, we hypothesized that suppressing IRX3 expression accelerates human working cardiomyocyte differentiation. Here, we demonstrate that depleting IRX3 enhances hiPSC-CM differentiation. IRX3-knockout (KO) hiPSCs generated a greater number of cardiomyocytes with elevated expression of TNNI1 and CX43. Notably, IRX3-KO cardiomyocytes exhibited improved electrophysiological properties, more uniform mitochondrial distribution, better sarcomere organization, and enhanced intercellular connectivity. We observed that IRX3 expression peaks during the early stages of cardiomyocyte differentiation, whereas IRX3-KO cardiac progenitors have increased expression of GATA4, NKX2–5, and TBX5, as well as enhanced cell proliferation. These integrative analyses indicate that IRX3 influences cardiomyocyte differentiation by modulating the gene regulatory networks driven by GATA4, NKX2–5, and TBX5, providing functional evidence linking gene regulatory networks to the structural and electrophysiological development of cardiomyocytes. Collectively, these findings identify IRX3 as a key regulator of early cardiac commitment and highlight the potential of IRX3 suppression to enhance the molecular and functional phenotype of hiPSC-derived cardiomyocytes.

Revisiting the role of structural connectivity-based parcellation in thalamic nuclei segmentation: Benchmarking against recent state-of-the-art methods

by Daniel H. Nguyen, Debottama Das, Ali Bilgin, Dianne Patterson, Matthew Hook, Chris Butson, Alberto Cacciola, Vinod Kumar Jangir, Manojkumar Saranathan

Leveraging diffusion tractography, connectivity-based parcellation (CBP) is one of the oldest methods for thalamic nuclei segmentation. The goal of this work was to reassess CBP using higher spatial resolution diffusion MRI data and reconstruction algorithms, and to compare it with recent state-of-the-art methods for thalamic nuclei segmentation. Furthermore, these methods were systematically evaluated against three histological atlases and one functional MRI–based atlas to examine their relative anatomical similarities and differences. High resolution diffusion and T1-weighted MRI data from 67 healthy individuals in the Human Connectome Project Young Adult database were analyzed. CBP was performed using probabilistic tractography with cortical targets derived from combining labels of the Human Connectome Project Multi-Modal Parcellation 1.0 atlas into 8, 11, and 23 regions. Results were compared against three recent methods: orientation distribution function clustering (ODF), track density imaging (TDI), and structural MRI-based segmentation. Group level analyses were conducted in the Montreal Neurological Institute space, and Dice overlap coefficients were calculated using four atlases (three histological, one functional). CBP results using newer data and methods were still remarkably similar to the original CBP parcellation results. Across atlases, a consistent hierarchy was observed: HIPS-THOMAS performed best, followed by TDI, ODF, and CBP (Kendall’s W = 1.00, p = 0.007). Histological atlases showed strong mutual agreement (Pearson r = 0.71–0.85), whereas the Zhang atlas demonstrated lower concordance (Pearson r = 0.51–0.63). Despite methodological advances, CBP remains constrained in its ability to delineate thalamic nuclei with histological accuracy. By contrast, structural and diffusion microstructural approaches provided better nuclear localization. These findings highlight the need for hybrid workflows that integrate structural and diffusion-based information to enable more reliable thalamic segmentation for neuroscience research.

Toward a fully wireless endovascular neural interface: Evaluating power transfer efficacy

by Yi-De Tai, Joel Villalobos, Nima Wickramasinghe, Bryce Widdicombe, Ranjith R. Unnithan, David B. Grayden, Sam E. John

Background

Endovascular neural interfaces (ENIs) offer a minimally invasive approach for neural stimulation and recording without the need for open brain surgery. However, current generation devices have long transvascular wires from the implant site to the chest. Eliminating these wires will unlock clinical usability, including lowering infection risk from transvascular wires, reducing the risk of thrombosis from altered hemodynamics, and improving mechanical reliability. However, removing these transvascular wires would require efficient power transfer across the skull and tissue while meeting specific absorption rate (SAR) limits, which is a significant challenge in the field.

Objective

This work designed and evaluated endovascular receiver (Rx) and transmitter (Tx) coils within endovascular geometric and biological constraints to maximize wireless power transfer.

Methods

This study evaluated the optimal operating frequencies, quantified coupling, coil quality factors, power transfer efficiency, and SAR using computational modeling, benchtop, and in-vivo testing. The study also assessed the tolerance to coil misalignment and load mismatch. We evaluated each case with and without ferrites with measurements in air, sheep tissue, and in vivo in sheep.

Results

The results showed that inductive power transfer delivered power to endovascular geometry devices at clinically relevant depths. The maximum power transfer efficiency (PTE) reached 11% at 15 mm and 2% at 30 mm, with up to 72 mW delivered at 30 mm under SAR safety limits. The rectangular planar coil pair performed best at ≤15 mm, whereas the ferrite-core flux-pipe Tx with a helical Rx outperformed beyond ~20 mm and was more tolerant to misalignment.

Conclusion

This study demonstrated the feasibility of wirelessly powering multichannel ENIs using coils that can be placed inside a blood vessel and powered inductively. Making an endovascular neural interface fully wireless has the potential to transform the technology by improving both safety and reliability.

Victim framing shapes attitudes across diverse contexts

by Stephen J. Flusberg, Asher Donnelly, J. D. Jarolimek, Esmé Nix, Lili B. Davis, Boshang Yin, Lindsey Anderson, Dylan Ciolfi, Kevin J. Holmes

A person accused of victimizing others may be described as the “real” victim by their defenders to garner empathy and mitigate blame. Recent research shows that this rhetorical strategy, known as “victim framing,” can increase support for a man accused of sexually assaulting a woman. Little is known, however, about its effects in other contexts. Across five experiments (N = 2,941), we investigated whether victim framing generalizes beyond prototypical sexual assault cases. Participants read fictionalized news reports where one party was labeled the victim (or neither was) and expressed support for the individuals involved. We found significant framing effects across diverse scenarios: (a) a man accused of sexual assault who self-described as the victim; (b) a woman accused of sexually assaulting a man; (c) same-sex assault allegations involving men or women; (d) a celebrity or stranger accused of physically assaulting his girlfriend; and (e) a police officer who shot an unarmed civilian. As in prior work, only participants who explicitly cited the victim-related language as influencing their evaluations showed robust and reliable framing effects. Multiple observer characteristics (e.g., gender, political ideology) predicted attitudes in expected ways, yet victim framing effects persisted when controlling for these individual differences. Taken together, these findings are consistent with a social-pragmatic account of victim framing: many people treat a victim label as communicating relevant information and adjust their evaluations accordingly, while others either do not draw this inference or weigh other information more strongly. Our findings highlight the power and limits of explicit forms of linguistic framing.

Religious ceremonies and the ethical development of medical sciences students: A qualitative study on participation barriers and perceived value

by Amir Hossin Moradpour Dehnavi, Abolfazl Alavi, Amin Beigzadeh, Ali Reza Yusefi

Religious ceremonies can play a pivotal role in shaping ethical values among medical sciences students. However, participation in such ceremonies is often influenced by multiple academic, social, and cultural factors. This study aimed to explore the perceived value of religious ceremonies and the barriers affecting student participation in these practices within the context of their ethical development. This qualitative study was conducted at Sirjan School of Medical Sciences in southern Iran from March to July 2025, using a latent content analysis approach grounded in the interpretivist paradigm. Semi-structured, in-depth interviews were conducted with 33 students from diverse academic programs and backgrounds. Data were analyzed inductively based on Graneheim and Lundman’s framework using MAXQDA 2022 software. Trustworthiness was ensured through Lincoln and Guba’s criteria including credibility, confirmability, dependability, and transferability. Seven main themes and twenty- four subthemes emerged. The themes included: (1) Time and Academic Pressure (e.g., course overload, exam clashes); (2) Perceived Irrelevance (e.g., disconnection from professional goals); (3) Cultural and Personal Beliefs (e.g., secular upbringing, concerns about religious imposition); (4) Social Dynamics (e.g., fear of judgment, peer influence); (5) Institutional Support (e.g., lack of promotion, insufficient facilities); (6) Perceived Ethical Value (e.g., development of professionalism and compassion); and (7) Emotional and Community Benefits (e.g., stress relief, sense of belonging, spiritual recharge). While religious ceremonies hold perceived ethical and emotional value for many students, numerous academic, institutional, and cultural barriers limit participation. Integrating religious practices into educational contexts in a more inclusive, flexible, and voluntary manner could enhance students’ moral development without alienating diverse beliefs.

Deep learning-based arterial waveform analysis for predicting postoperative cerebrovascular events in pediatric patients with Moyamoya disease

by Jung-Bin Park, Youmin Shin, Jihun Kim, Yoon Jung Kim, Seung-Bo Lee, Eun-Hee Kim, Joo Whan Kim, Seung-Ki Kim, Hee-Soo Kim, Young-Gon Kim

Background

Postoperative cerebrovascular events, including transient ischemic attacks, infarctions, and hemorrhages, remain a significant concern in pediatric patients with Moyamoya disease (MMD)undergoing surgical revascularization. This study aimed to develop an explainable deep learning-based classification model using intraoperative arterial blood pressure (ABP) waveform analysis for postoperative cerebrovascular events in pediatric patients undergoing surgery for MMD, with exploratory analysis of associated waveform-derived physiologic features.

Methods

This retrospective study included 181 pediatric patients (≤18 years) who underwent revascularization surgery for MMD, with an independent temporal holdout cohort of 79 patients reserved for validation. ABP signals were preprocessed using detrending, pulse segmentation, and normalization, then converted into image representations for deep learning classification. Various convolutional neural network (CNN) models, including ResNet50, ResNet34, DenseNet121, VGG16, and VGG19, were evaluated against Vision Transformer (ViT) architectures. Multiple image transformation methods were tested, and Grad-CAM analysis and statistical comparisons of waveform-derived physiologic features were conducted between patients with and without postoperative cerebrovascular events.

Results

The optimal model configuration achieved the best performance using raw pulse waveforms with three consecutive pulses per image. CNN-based models outperformed ViT-based models, with the highest internal classification performance observed using raw pulse waveforms (AUROC = 0.772, SD = 0.070).In the independent temporal validation cohort, the model achieved an AUROC of 0.738 ± 0.011 at the patient level. Grad-CAM visualization highlighted the diastolic runoff phase as a region of interest for classification. Four waveform-derived features related to arterial compliance were significantly associated with postoperative cerebrovascular events (p  Conclusions

In this study, CNN-based deep learning models demonstrated the feasibility of predicting postoperative cerebrovascular events from intraoperative ABP waveforms, with diastolic runoff dynamics emerging as a potentially relevant physiologic pattern. These findings are exploratory and require prospective multi-center validation before clinical application.

Trends in the burden of sickle cell disorders in Sierra Leone, 1990–2023: An analysis of Global Burden of Disease Study 2023 estimates

by Monalisa M. J. Faulkner, Fatima Jalloh, Foray Mohamed Foray, Sahr L. Gborie, Mohamed B. Jalloh

Background

Sickle cell disease is a major cause of childhood mortality in sub-Saharan Africa, yet country-specific burden estimates for high-prevalence settings in West Africa remain limited.

Objective

To describe Global Burden of Disease (GBD) 2023 modeled estimates of sickle cell disorders burden in Sierra Leone from 1990 through 2023, including temporal trends, age and sex patterns, and demographic contributors to mortality change.

Methods

We analyzed GBD 2023 modeled estimates for sickle cell disorders in Sierra Leone, including prevalence, deaths, years lived with disability (YLDs), years of life lost (YLLs), and disability-adjusted life-years (DALYs) as absolute counts and age-standardized rates. Temporal trends in age-standardized rates were assessed using log-linear regression. The Kitagawa-Das Gupta decomposition partitioned the change in estimated deaths into population growth, age-structure change, and age-specific mortality-rate changes.

Results

Estimated prevalent cases increased from 48,689 (95% UI, 42,588−56,140) in 1990–90,498 (78,126−105,815) in 2023. Estimated deaths increased from 408 (288−579) to 635 (438−862), while the estimated age-standardized mortality rate declined from 10.2 to 7.9 per 100,000 (APC, −0.46%; 95% CI, −0.64 to −0.29). Decomposition attributed 159.6% of the net increase in deaths to population growth, −7.8% to age-structure change, and −51.8% to lower modeled age-specific rates. In 2023, an estimated 49.5% of deaths occurred before age 20. Point estimates suggested possible higher male mortality, but uncertainty intervals were wide and compatible with no clear sex difference.

Conclusions

GBD estimates suggest that Sierra Leone’s absolute burden of sickle cell disorders increased substantially between 1990 and 2023, while modeled rates declined. These modeled estimates highlight a growing absolute burden and persistent early-life mortality, supporting the need for improved surveillance, newborn screening, infection prophylaxis, hydroxyurea access, and longitudinal care systems.

Evaluation of non-invasive hemoglobin measurement in blood donors at a tertiary care hospital, Bangkok, Thailand

by Ratinan Dangwilailert, Somboon Lekmak, Duangtida Promlee, Tanyaporn Pongkunakorn, Parichart Permpikul

Background

Hemoglobin (Hb) assessment is crucial to prevent blood donation from anemic donors. Most measurements are invasive and painful; however, an alternative, non-invasive hemoglobin measurement is available. This study aimed to compare non-invasive and point-of-care invasive hemoglobin test results with those from an automated blood analyzer in blood donors.

Methods

Qualified blood donors were enrolled at a tertiary care hospital in Bangkok, Thailand. Hemoglobin was initially measured by the non-invasive device (Rad-67 Pulse CO-Oximeter) and a point-of-care invasive hemoglobin screening device (Mission HemoPro). Participants with point-of-care invasive hemoglobin ≥ 12.5 g/dL were eligible to donate, and during donation, standard hemoglobin measurements were obtained using an automated analyzer, XN-550. Those who were ineligible with point-of-care invasive hemoglobin  Results

Of 300 participants, 295 had complete data. Of these, 169 were male (57.28%). Average non-invasive, point-of-care, and automated hemoglobin levels were 14.38 ± 1.12 g/dL, 13.65 ± 0.70 g/dL, and 13.90 ± 1.16 g/dL, respectively. The ICC between non-invasive, point-of-care, and automated hemoglobin measurement was 0.600 (95% CI: 0.522–0.668) and 0.897 (95% CI: 0.872–0.957). The sensitivity of the non-invasive Hb measurement was poor for detecting anemic donors when the Hb cut-off was set at 12.5 g/dL. This method received significantly higher satisfaction than the routinely used invasive device.

Conclusion

The non-invasive Hb measurement in blood donors showed moderate agreement with the standard test, but the sensitivity was poor when the cut-off hemoglobin was set at 12.5 g/dl. Since donor satisfaction was higher, this method may be used as an alternative screening tool, provided a higher Hb cut-off value is used.

Mass casualty incident preparedness and response: A desk review of the Code Orange Plan and Assessment of Healthcare Workers’ Knowledge, Attitudes, and Practices in a Lebanese Tertiary Government Hospital

by Linda Abou-Abbas, Rima Kashash, Mustapha Khalife, Mohamad Shafic Ramadan

Background

Effective preparedness and response to mass casualty incidents (MCI) are essential for hospital safety, operational efficiency, and the delivery of timely, high-quality patient care during emergencies. This study assessed a tertiary government hospital in Lebanon’s Code Orange plan by reviewing documentation for alignment with international guidelines and evaluating staff knowledge, attitudes, and practices (KAP) regarding MCI preparedness.

Methods

Documents reviewed at Rafik Hariri University Hospital (RHUH) included the current Code Orange plan, relevant policies, and international guidelines. A comprehensive evaluation framework was used, focusing on preparedness, incident command systems, communication, and management. A comparison with established standards was conducted to identify gaps. Complementing this, a cross-sectional study was conducted using a convenient sample of medical and non-medical healthcare workers to evaluate their KAP regarding MCI preparedness.

Results

The desk review of the RHUH Code Orange plan identified both strengths and significant gaps in MCI preparedness. While the plan defines staff roles and resources for emergency response, it lacks detailed procedures for activation strategies, surge capacity, continuity of essential services, and triage processes. Additionally, post-event recovery protocols are insufficient or absent, and the importance of regular drills is not adequately emphasized. The KAP study revealed significant differences between medical and non-medical staff in terms of MCI knowledge, involvement, and training engagement, with medical staff reporting higher levels of familiarity and desire for participation.

Conclusion

The findings underscore the need to bridge knowledge and engagement gaps between medical and non-medical staff to enhance MCI response. Key actions include interdisciplinary training to build coordination, clear communication protocols to streamline information flow, and routine drills with defined roles to strengthen preparedness. Additionally, implementing performance monitoring during drills and real MCIs, along with conducting regular evaluations, will allow for continuous refinement of response strategies.

Gut microbiome alterations among Ghanaian children with asymptomatic malaria infections

by Amma Aboagyewa Larbi, Moses Etsey, Obed Brew, Bismark Koduah, Rosemond Enam Mawuenyega, Emmanuel Kobla Atsu Amewu, Nehemiah Kweku Essilfie, Solomon Wireko, Alexander Kwarteng, Ben Adu Gyan

The human gut microbiome, consisting of bacteria, archaea, fungi, and viruses, influences various physiological processes of the body. The gut microbiome composition is shaped by factors such as diet, geography, and antibiotic use. Malaria has been a global health challenge over the years, especially in low- and middle-income countries. This study investigated how asymptomatic malaria infection altered gut microbial communities in Ghanaian children, offering insights for novel malaria control strategies. Standard aseptic phlebotomy procedures were employed to collect venous blood samples for Plasmodium species detection. The gut microbial community was profiled by sequencing the 16S rRNA V4 region, and sequence data were processed using the DADA2 pipeline in R. Asymptomatic malaria infections were predominantly mixed with P. falciparum and P. malariae. Microbiome analysis revealed that Firmicutes and Bacteroidetes comprised nearly 70% of the total microbial population. Asymptomatic individuals showed a decrease in Firmicutes abundance from 52.5% to 44.0% and an increase in Bacteroidetes from 34.7% to 45.6%. There was also a slight increase in the abundance of Proteobacteria from 3.0% to 4.8%. At the genus level, Prevotella_9 was the most abundant and exhibited the highest variability in the infected groups. The Alloprevotella and Streptococcus genera increased in both infected groups, but Escherichia-Shigella was significantly elevated in only those with mixed infections. Faecalibacterium significantly declined in asymptomatic malaria-infected individuals compared to healthy controls, with variability further reduced in mixed infections. Beta-diversity analysis indicated a significant effect of malaria status on microbial composition (PERMANOVA, p 

Factors affecting feeding choices in infants and toddlers in northern Jordan: A cross-sectional study

by Wajdi Amayreh, Mohammad Al-Magableh, Jomana Alsulaiman, Mahdi Alshboul, Maan Amayreh, Ahmad Al-Maqableh, Razan Qasem, Tamara Al-Nemrat

Background

Breastfeeding is a key determinant of infant health and survival; however, exclusive breastfeeding (EBF) rates remain low worldwide. Various maternal, infant, and socioeconomic factors influence the feeding practices.

Objective

The main objective of this study was to identify maternal, infant, and socioeconomic determinants of infant feeding practices during the first six months of life among mothers in northern Jordan.

Methods

A prospective cross-sectional study was conducted at Princess Rahma and Prince Rashid Hospitals in Irbid City, northern Jordan, from December 2023 to February 2024. Mothers of healthy infants aged 6–24 months participated in a survey that gathered information on their demographics, feeding practices, and other infant-related details. Statistical analyses were performed to identify the associations and key predictors of feeding type.

Results

Among the 508 mothers who participated in this study, 29.9% were exclusively breastfeeding, 46.5% used mixed feeding, and 23.6% opted for formula feeding. The key factors influencing these choices include maternal health issues, work hours, and infant birth weight. Maternal illness was identified as the strongest predictor of exclusive artificial feeding (AOR = 12.72; 95% CI: 4.10–39.45; P  Conclusion

This study highlighted the low exclusive breastfeeding rate, emphasizing the need for improved support systems to encourage breastfeeding in the form of workplace accommodations and healthcare counseling to address barriers to its practice.

Prevalence and associated factors of meconium aspiration syndrome among neonates admitted to Neonatal Intensive Care Units in Public Hospitals of Harari Region, Eastern Ethiopia

by Jabir Aman, Bikila Balis, Naol Oda, Dawit Tamiru, Tadesse Gure Eticha, Dawit Firdisa, Aboma Motuma

Background

Meconium aspiration syndrome is a life-threatening respiratory disease affecting around 5% of neonates worldwide. Although several studies have been conducted in developed countries, data on meconium aspiration syndrome and its associated factors remain limited in low-resource settings, including Ethiopia. Therefore, this study aimed to determine the meconium aspiration syndrome and associated factors among neonates admitted to the neonatal intensive care unit at public hospitals in Harari region, Eastern Ethiopia.

Method

A retrospective hospital-based cross-sectional study design was conducted among all neonates admitted from January 1 to December 30, 2023 and data were extracted from patient charts during April 1–30, 2025. A simple random sampling technique was employed to select 417 charts of neonates admitted to the neonatal intensive care unit. The data were collected by a data extraction checklist via Kobo Toolbox. Descriptive statistics and binary logistic regression were used in SPSS version 25 (IBM Corp., Armonk, NY, USA) for the analysis. Adjusted odds ratios with 95% confidence intervals were used to declare statistical significance at a p-value ≤ 0.05.

Results

The prevalence of meconium aspiration syndrome among neonates admitted to the neonatal intensive care unit was 24.2% [95% CI, 20.2–28.6]. Factors significantly associated with meconium aspiration syndrome were post-term gestation [AOR = 9.05, 95% CI 2.38–34.41], antepartum hemorrhage [AOR = 3.34, 95% CI 1.31–8.60], prolonged labor [AOR = 3.06, 95% CI 1.27–7.36], premature rupture of membranes [AOR = 3.65, 95% CI 1.28–10.45], low Apgar scores at 5th minute [AOR = 11.27, 95% CI 3.44–36.92] and intrapartum thick meconium passage [AOR = 5.98, 95% CI 2.6–13.6].

Conclusions and recommendations

These findings indicate a high prevalence of meconium aspiration syndrome, and to reduce its impact, targeted clinical interventions should be implemented. Pregnancies reaching 42 weeks of gestation, prolonged labor, and high-risk conditions such as antepartum hemorrhage, premature rupture of membranes, or the presence of thick meconium are important factors to consider. Careful monitoring and appropriate management may be warranted in these cases.

Analyzing the collaborative development needs of grassroots centers for disease control and prevention using the Kano model: A case study of China’s Chengdu–Chongqing Economic Circle

by Yang Tong, Huang Qianzhen, Tan Bo, Hu Bin, Zhang Min

Background

Advancing the development of centers for disease control and prevention (CDCs) has become a priority within global public health governance. However, public health governance capacity varies significantly among CDCs across different countries and regions, grassroots CDCs face particular disadvantages. Establishing stable, efficient collaborative development mechanisms among CDCs across diverse regions to maximize overall effectiveness and ensure sustainable development represents a critical public health science issue.

Objective

This study aims to provide scientific references and a theoretical foundation for the coordinated development of grassroots CDCs within the Chengdu–Chongqing Economic Circle (CCEC) and the construction of public health systems.

Methods

A questionnaire for collaborative development needs indicators in grassroots CDCs, comprising 4 primary needs and 13 secondary needs, was developed through literature review, the Delphi expert consultation method, and the Kano model. Analysis focused on questionnaires collected from eight grassroots CDCs within the CCEC. The importance of needs was ranked using the better–worse coefficient and satisfaction sensitivity analysis.

Results

Analysis of the 110 valid questionnaires showed that for the must-be attribute, satisfaction sensitivity ranked as follows: performance compensation (0.883)> talent exchange and scientific research and innovation cooperation (0.824)> public health emergency rescue mechanism (emergency material reserve and cross-regional material mobilization; 0.817)> cross-regional case monitoring, investigation, and tracking (0.775). Regarding the one-dimensional attribute, the satisfaction sensitivity ranking was joint risk assessment and emergency command (0.937)> business archive co-construction and sharing mechanism (emergency response plan, and technical scheme) (0.909)> regional co-construction and sharing between the university and the local area (0.832). For the attractive attribute, the satisfaction sensitivity ranking was regional monitoring and early-warning information management system (0.922)> community chronic disease prevention and service (0.804)> coordinated transfer and diversion diagnosis and treatment of patient with infectious diseases within the region (0.734). However, the collaborative release and interaction mechanism of social integrated media information, public health collaborative governance entities, and the construction of a cross-regional expert database constitute indifferent attributes.

Conclusions

This study provides preliminary scientific evidence for the precise allocation of public health resources and the establishment of localized collaborative development mechanisms. Simultaneously, the research methodology and analytical framework offer new theoretical references for similar studies in other regions globally.

Rhinovirus/enterovirus contribution to respiratory-associated hospitalizations in adults during respiratory seasons in Spain: A 6-year prospective study

by Sandra S. Chaves, Valérie Bosch Castells, Ainara Mira-Iglesias, Joan Puig-Barberà, F. Xavier López-Labrador, Miguel Tortajada-Girbés, Mario Carballido-Fernández, Joan Mollar-Maseres, Germán Schwarz-Chávarri, Javier Díez-Domingo, Alejandro Orrico-Sánchez, Valencia Hospital Network for the Study of Influenza and other Respiratory Viruses (VAHNSI)

Background

Understanding the burden of acute viral respiratory infection-related hospitalizations is crucial for guiding research and development. Unlike influenza, respiratory syncytial virus (RSV), or severe acute respiratory syndrome coronavirus 2, no pharmaceutical interventions exist for other respiratory viruses; therefore, their impact remains poorly characterized. This study aimed to investigate the association of current non-vaccine-preventable respiratory viruses, especially rhinovirus/enterovirus (RV/EV), on hospitalizations during the respiratory seasons.

Methods

Data from a prospective study that used multiplex polymerase chain reaction to conduct long-term surveillance on respiratory viruses in Valencia, Spain were analyzed. Patients aged ≥50 years hospitalized due to respiratory illness from 2014–15–2019–20 were included.

Results

Respiratory viruses were detected in 35.2% (3,755/10,675) of hospitalized patients with acute respiratory illness. Influenza and RSV accounted for 22.1% of hospitalizations, RV/EV for 7.6%, and other non-vaccine-preventable viruses for 5.4%. Adults ≥75 years had average seasonal hospitalization incidence rates more than twice those aged 65–74 years and eight times those aged 50–64-year-olds. No significant differences in severity markers were observed among patients with or without virus identified, those aged ≥75 years had a 2–3 times higher mortality rate compared to younger age groups.

Conclusions

The potential impact of respiratory viruses on hospitalization rates among older adults, particularly those aged ≥75 years, highlights the need for targeted interventions to reduce healthcare system burden. Enhanced diagnostic capabilities and the development of next-generation preventive strategies, including vaccines and therapeutics, could improve patient outcomes and strengthen the resilience of the healthcare system during respiratory virus seasons.

Extensive intraoperative peritoneal lavage (EIPL) for gastric cancer with positive peritoneal lavage and/or stamp cytology: An exploratory phase II study

by Gen Tsujio, Masakazu Yashiro, Yuichiro Miki, Kohei Matsuoka, Koji Maruo, Mami Yoshii, Tatsuro Tamura, Katsunobu Sakurai, Takahiro Toyokawa, Naoshi Kubo, Shigeru Lee, Tomohisa Okuno, Kishu Kitayama, Go Masuda, Masaichi Ohira, Kiyoshi Maeda

Background

Our group revealed that the combination of intra-operative stamp cytology and peritoneal lavage cytology (CY) improved the identification of individuals with high risk of peritoneal metastasis. In this exploratory Phase II study, we aimed to evaluate the effect on relapse-free survival (RFS) of extensive intraoperative peritoneal lavage (EIPL) for gastric cancer with positive peritoneal cytology (CY1) and/or stamp cytology positive (stamp+).

Materials and methods

This study was a single arm, multi-institutional, exploratory phase 2 trial to assess the effects of EIPL after open gastrectomy for gastric cancer with CY1 and/ or stamp+. The primary endpoint was RFS. Secondary endpoints were overall survival (OS), postoperative recurrence site and incidence of postoperative adverse events.

Results

Between 2017 and 2021, 13 patients from 2 institutions were enrolled in this study. Because of the recent decline in open abdominal surgery, the number of cases did not increase and the trial was closed due to lack of applicants at 13 cases. Median 3-year RFS was 14.5 months (95% CI 5.4-NA), median 3-year OS was not reached (95% CI 14.5-NA) and median3-year peritoneal RFS was 16.0 months (95% CI 5.4-NA). Median 3-year peritoneal RFS rate was 83% in CY0 and stamp+ cases (n=6), and 0% in CY1 and stamp+/- cases (n=7). (Log-rank p=0.015).

Conclusion

Because of the slow accrual pace and early stop of the trial, we were not able to evaluate the prespecified endpoints thoroughly. However, EIPL might be effective to prevent perineal recurrence, especially in CY0 and stamp+ case.

Complications and mortality following percutaneous and laparoscopic liver biopsy: A multicenter study in a resource‑limited healthcare system

by Nadieh Abdallah, Ahed Almahdi, Diana Shella, Rasha Al-Masri, Iyad Maqboul, Mohammad Jaber, Ramzi Shawahna

This study was conducted to assess the incidence and types of complications and mortality following liver biopsy, and to identify independently associated factors that can inform clinical practice in a resource‑limited healthcare system. A retrospective multicenter study was conducted across six major hospitals between January 2020 and December 2025. Medical records of 218 patients undergoing percutaneous and laparoscopic liver biopsies were reviewed. Demographic, clinical, laboratory, procedural, and outcome variables were extracted using a validated data collection form. Inferential analyses were conducted using chi‑square, Fisher’s exact, and Mann‑Whitney U tests, while multivariate logistic regression models were employed to identify factors independently associated with complications and mortality. The most common types of complications were infection (n = 7, 3.2%) and hemorrhage (n = 6, 2.8%), followed by pulmonary complications (n = 4, 1.8%), metabolic disturbances (n = 3, 1.4%), and acute kidney injury (n = 2, 0.9%). Mortality was recorded in 6 patients (2.8%). Higher pre-operative white blood cell count was independently associated with infections (OR: 1.28, 95% CI: 1.02–1.62, p = 0.036). Older age was independently associated with mortality (OR: 1.07 per year increase, 95% CI: 1.01–1.15, p = 0.035). Hemorrhage and pulmonary complications were more frequent after laparoscopic biopsy and under general anesthesia, although these associations did not remain significant in adjusted models. This study provides the first systematic evidence on liver biopsy safety in Palestine, a resource‑limited healthcare system, thereby filling a critical gap in the regional literature. The study identified pre-operative increases in white blood cell count as a predictor of infection and older age as a predictor of mortality. These simple, pragmatic markers can guide monitoring and risk stratification in constrained environments, offering actionable insights for clinicians and policymakers. Future studies should be conducted to evaluate whether these markers can help reduce complications and mortality.

Background

The neonatal period is the most vulnerable time for an infant’s survival, particularly for preterm neonates. Preterm birth is among the leading causes of neonatal mortality. Many neonatal complications can be prevented, but preterm birth remains a leading cause of admission, death, and long-term complications, highlighting the need for further research on outcome and survival disparities across populations and settings. Therefore, this study aimed to assess survival status and predictors of mortality among preterm neonates admitted to neonatal intensive care units at public hospitals in the Harari region and Dire Dawa administration, Eastern Ethiopia, from November 1, 2021 to October 30, 2024.

Methods

The hospital-based retrospective cohort study was conducted among preterm neonates admitted to the neonatal intensive care unit at public hospitals of the Harari region and Dire Dawa administration, Eastern Ethiopia. A simple random sampling technique was used, and data were extracted from neonates’ medical records and registration formats using a structured checklist prepared in English. Descriptive statistics, life table, Kaplan-Meier curves, and Log-rank test were used to estimate and compare survival time. Predictors of mortality were identified using the Cox Proportional Hazard model.

Results

Out of 612 preterm neonates, 205 (33.5%; 95% CI: 29.76–37.39) died, corresponding to an incidence rate of 52.76 deaths per 1,000 preterm neonate-days (95% CI: 46.01–60.50), with a median survival time of 18 days. As multivariable cox-regression result,  ≥ 4 antenatal care contact (AHR = 0.56; 95% CI: 0.36–0.89), receiving KMC (AHR = 0.16; 95% CI: 0.09–0.27), 5th minute APGAR score Conclusion

The incidence of preterm neonatal mortality was high in this study. Adequate Antenatal care (ANC) and kangaroo mother care (KMC) significantly improved preterm survival, while low APGAR score, resuscitation with bag and mask, neonatal sepsis, PNA, and RDS were major predictors of preterm neonatal death. Emphasis should be placed on strengthening antenatal and perinatal care, along with early detection and management of identified neonatal complications.

Mycoplasma iowae is an economically significant pathogen that causes reduced hatchability, late embryo mortality and leg deformities, chondrodystrophy and skeletal lesions in poults. While prevention is essential in the control of infection, the appropriate administration of antibiotics may reduce economic losses during outbreaks. As a first step in the exploration of antimicrobial resistance mechanisms in M. iowae, target modification and efflux pump activity were examined in the present study. Point mutations were analyzed in previously described antibiotic binding sites in the whole genome sequences of 99 M. iowae strains. Mismatch amplification mutation assays (MAMAs) were designed and validated for the differentiation of mutations corresponding to elevated minimum inhibitory concentration (MIC) values for fluoroquinolones. Broth microdilution assays were performed to evaluate the effect of efflux pump inhibitors. In the presence of orthovanadate (OV), MIC values were significantly lower than in the absence of OV for spiramycin, tilmicosin, tylosin and oxytetracycline, which may indicate the presence of an active efflux system in M. iowae. Putative promoter regions of efflux-related genes were predicted and characterized. Genetic mutations, previously described in other bacteria, were described to be associated with elevated fluoroquinolone, macrolide and lincomycin MICs in M. iowae, although certain resistant phenotypes remained unexplained, promoting future examinations for deeper insights. The developed MAMAs may support rapid identification of M. iowae strains with elevated MIC values for fluoroquinolones. The better understanding of the efflux pump mechanisms enables the development of alternative methods for the support of therapy against this pathogen.

Utilization of the posterior iliac line for visualizing posterior column screws in obturator oblique view

by Hongtao Li, Li Xu, Longxin An, Xiaojing Li, Linjing Zhang, Jun Liu, Kaili Zhai, Xuecheng Sun, Naibo Feng

Purpose

To evaluate whether posterior column screws penetrate the posterior cortical surface of the acetabulum when assessed using obturator oblique radiographic imaging.

Methods

Computed tomography (CT) scans were performed on the right acetabulum of 50 healthy adults to measure the angle (α) between the posterior wall of the acetabulum and the sagittal plane at the level of the femoral head’s maximal diameter. In addition, five cadaveric pelvises were subjected to C-arm fluoroscopic imaging. A 6 cm long, 1.5 mm Kirschner wire was positioned along the posterior surface of the acetabular posterior column, aligned with the greater sciatic notch, and imaged in both the 45° and α-degree obturator oblique views. The radiographic line visualized from the Kirschner wire in the obturator oblique view was defined as the posterior iliac line, and its anatomical relationship with the posterior surface of the posterior column was analyzed. Subsequently, a 2.5 mm Kirschner wire was inserted into the posterior column at the standard entry point for screw placement using an electric drill, with the wire tip intentionally positioned between the posterior iliac line and the posterior rim in the 45° obturator oblique view. The trajectory of the wire was assessed under both 45° and α-degree obturator oblique views to determine its relation to the osseous corridor.

Results

The measured angle between the posterior surface of the acetabular posterior column and the sagittal plane was (60.2 ± 2.5)°. In the 45° obturator oblique view, the posterior iliac line corresponded with the outer edge of the iliac crest superiorly and the outer edge of the ischium inferiorly, while the posterior wall was projected posterior to the midpoint of the posterior iliac line. In the α° obturator oblique view, the posterior iliac line maintained this alignment but intersected centrally with the posterior acetabular wall. The 2.5 mm Kirschner wire remained within the osseous corridor under the 45° view but potentially extended beyond it under the α° view.

Conclusion

When the posterior column screw is visualized posterior to the posterior iliac line in the 45° obturator oblique view, further assessment using a α° view is necessary. If the screw appears anterior to the posterior iliac line in the α° view, it indicates that the posterior cortical surface has not been breached.
