Response of mid-lactation primiparous Holstein cows to the supplementation of rumen-protected methionine during the summer

by Caio R. Monteiro, Victor Augusto de Oliveira, Rabeche Schmith, João Pedro A. Rezende, Tales L. Resende, João A. Negrão, Marina A. C. Danés

This study aimed to evaluate the effects of rumen-protected methionine (RPM) supplementation on productive and physiological responses of primiparous Holstein cows during summer. We hypothesized that RPM supplementation would maintain or improve milk yield and composition due to beneficial physiological, redox, and inflammatory responses in cows exposed to summer heat. The trial was conducted in a randomized block design during nine weeks in Brazil using 80 primiparous cows (182 ± 64 DIM; 42.9 ± 4.7 kg/d milk). Cows were blocked by milk yield and DIM and assigned to a control diet (CON; no added RPM) or the same diet supplemented with RPM (Mepron®, Evonik) at 0.75 g/kg diet dry matter, targeting 20 g/cow/day (product contains 62% metabolizable methionine) to the average cow. Milk yield and composition, vaginal temperature, respiratory rate, and plasma samples were collected in weeks 3, 6, and 9. Data were analyzed using mixed models including treatment, week, and their interaction as fixed effects, and block and cow as random effects. Cows were maintained under naturally occurring summer conditions. Environmental monitoring during weeks 3, 6, and 9 indicated elevated temperature–humidity index (THI) values, with values remaining above the heat-stress threshold (THI > 68) for 68.3% of the monitored hours (mean THI = 70.6; range 61.0–84.4). Overall (least squares mean across weeks 3, 6, and 9), RPM increased milk yield by 2.0 kg/d (44.9 vs. 42.9 kg/d), protein yield by 50 g/d (1,464 vs. 1,414 g/d), lactose yield by 108 g/d (2,109 vs. 2,001 g/d), and total solids yield by 176 g/d (5,331 vs. 5,155 g/d). Lactose concentration was lower in RPM (4.71 vs. 4.76%). Fat yield was unaffected, but a treatment × week interaction was observed for fat content. Milk fatty acid (FA) profile was unchanged, although treatment × week interactions were observed for individual fatty acids (C16:0, C18:0, C18:1, and preformed FA). Plasma glucose was lower, and insulin was higher in RPM than in CON cows (39.3 vs. 43.2 mg/dL and 0.52 vs. 0.35 ng/mL, respectively). Antioxidant capacity improved, with RPM cows having greater ferric reducing antioxidant power (32.9 vs. 28.5 µM) and lower malondialdehyde (2.48 vs. 2.78 nmol/mL). Other biochemical, inflammatory, and immune markers were unaffected. Respiratory rate was slightly higher in RPM than in CON cows (55 vs. 50 breaths/min). Mean vaginal temperature did not differ between treatments; however, a treatment × time × hour interaction was observed. Supplementation with RPM improved milk and solids yield, and enhanced antioxidant capacity and insulin levels, supporting its use to improve metabolic resilience under warm conditions.

Impact of postoperative macular comorbidity on visual outcomes after Descemet’s membrane endothelial keratoplasty: A multicenter analysis

by Naoya Nakagawa, Ami Igarashi, Hideaki Yokogawa, Akira Kobayashi, Tomomi Higashide, Satoru Yamagami, Takahiko Hayashi

The aim of this study was to identify the clinical factors associated with postoperative visual acuity following Descemet’s membrane endothelial keratoplasty (DMEK), with emphasis on the impact of macular diseases. This retrospective multicenter study included consecutive eyes that underwent DMEK between March 1, 2011, and June 30, 2022, and had available optical coherence tomography findings. Eyes with other ocular diseases causing visual loss were excluded. Overall, 77 eyes of 66 patients were included in the study. Univariable and multivariable regression analyses were performed to identify the predictors of best-corrected visual acuity (BCVA) at the final follow-up. Worse preoperative visual acuity and macular comorbidity were identified as independent predictors of poorer postoperative BCVA. Among macular pathologies, cystoid macular edema was most strongly correlated with reduced vision in the univariable analysis (β = 0.195; p = 0.016). In the subgroup analysis, worse preoperative visual acuity and macular comorbidity remained significant predictors (p

Identification and validation of genes encoding humoral specificity for the chemical allergen toluene diisocyanate

Por: Adam V. Wisnewski · Jian Liu — Febrero 26th 2026 at 15:00

by Adam V. Wisnewski, Jian Liu

A panel of hybridomas specific for different isomers of toluene diisocyanate (TDI), a cross‑linking chemical used in polyurethane production, has been previously described. These hybridomas were originally developed by researchers at the USA’s National Institute for Occupational Safety and Health (NIOSH). We sought to determine the DNA sequence encoding these TDI-specific monoclonal antibodies, enabling identification of germline gene rearrangement resulting in chemical specificity as well as production of the mAbs recombinantly. B cell receptor sequencing (BCR-seq) of hybridoma RNA readily identified productive heavy and light chain antibody sequences. The productive light chains of all 7 hybridomas showed strong identity with different genomic variable (V) and joining (J) region sequences with few changes from germline configuration. However, the productive heavy chains contained more substantial changes in their genomic V and J-region sequences consistent with antigen-driven affinity maturation, as well as N- and P- nucleotide additions comprising their complementarity-determining region 3 (CDR3). The hybridoma-defined TDI-specific mAbs were subsequently produced recombinantly in a human embryonic kidney cell line expression system, purified, and tested for their binding capacity against albumin derivatized with TDI, related diisocyanates, and control antigen. The recombinant versions of the TDI-specific mAbs demonstrated binding capacity for different isomers (2,4 and 2,6) of TDI consistent with that previously reported for the hybridoma secreted clones; one specific for 2,4-TDI, one specific for 2,6-TDI, three that bind both 2,4- and 2,6-TDI, and two that show cross-reactivity with 4,4′‑methylene diphenyl diisocyanate (MDI). None of the recombinant mAbs bound to aliphatic hexamethylene diisocyanate (HDI), its oligomer, or control antigen. Additional recombinant versions of the TDI mAbs, with identical V-regions, but different C-regions, demonstrated the dependence of antigen specificity on the V-region, but also highlighted the potential for C-region sequence to affect their detection in ELISA assays. The DNA sequences defined herein may be useful to other investigators wishing to generate recombinant TDI-specific mAbs as detection reagents for research or as standards for clinical serology tests.

Cultural and linguistic responsiveness in long-term care: A scoping review protocol on programs for residents and staff

Por: Wenting Yan · Carmel L. Montgomery · Liz Dennett · Stephanie A. Chamberlain — Febrero 26th 2026 at 15:00

by Wenting Yan, Carmel L. Montgomery, Liz Dennett, Stephanie A. Chamberlain

Background

The demographic landscape of Western countries has shifted to a more diverse one. Along with the trend of an aging population, a new problem has emerged, which is the increased linguistic diversity in the aging population in these countries. As people age and their care needs increase, they may not receive optimal care if they don’t speak the same language as their caregivers in long-term care facilities. Culturally and linguistically responsive long-term care services are important to ensure the best care for an aging population, but there is limited evidence in the literature on the scope and practice of these services. The objective of this scoping review is to map out the types of CLR programs in LTC settings and examine their core components and target populations.

Methods

The Arksey and O’Malley framework, further developed by Levac and colleagues, will be employed in this scoping review. The research question was framed using the PCC framework. A comprehensive systematic search was developed with an experienced librarian and will be conducted in Scopus, CINAHL, Embase, Medline, PsycINFO, and Academic Search Complete. All primary study designs, including quantitative, qualitative, and mixed methods, will be included. Studies must focus on culturally and linguistically responsive care programs used or implemented in long-term care services. There will be no date or language limitations. Findings will be thematically synthesized to answer the research question.

Conclusion

This review protocol provides a transparent process for how it will be conducted. We aim to contribute to a better understanding of what culturally and linguistically responsive care programs exist, how cultural and linguistic responsiveness is currently addressed across diverse care environments, and what gaps remain in long-term care.

A pilot study on the acoustic effects of a pseudo-palatal plate on speech: Implications for articulatory rehabilitation devices

Por: Seong Tak Woo · Sungdae Na — Febrero 26th 2026 at 15:00

by Seong Tak Woo, Sungdae Na

Intraoral palatal plates used in electropalatography (EPG) and tongue-interface systems are designed to monitor articulatory movement with minimal disruption to speech. However, their presence may subtly influence acoustic characteristics by altering tongue mobility and intraoral airflow. This study examines the acoustic effects of a pseudo-palatal plate during the articulation of consonants and vowels. Speech samples from healthy adults were recorded with and without the plate and analyzed using spectral and phonatory measures, including Mel-frequency cepstral coefficients (MFCCs), second formant (F2) slope, jitter, shimmer, harmonics-to-noise ratio (HNR), and quadrilateral vowel space area (qVSA). MFCC-based correlation coefficients and F2 slopes remained highly consistent across conditions, indicating minimal impact on consonant articulation. Shimmer (−0.72%), HNR (+2.5 dB), and qVSA (−24.1%) exhibited directionally consistent changes, with qVSA trending toward reduction; however, overall variation was limited. Vowel formant structures and consonant production were preserved mainly, suggesting that the palatal plate did not significantly impair vocal function. These findings support the interpretation that observed acoustic shifts are more consistent with filter-level effects than with changes at the glottal source. Although palatal plates may introduce minor acoustic variations, their impact on speech production appears minimal, reinforcing their suitability for therapeutic and assistive use, provided that acoustic considerations are addressed during design and clinical implementation.

The association between epicardial adipose tissue thickness and diabetes mellitus, hyperlipidemia, hepatosteatosis, pancreatic steatosis and pancreatitis

Por: Ece Zengin · Aybuke Ucgun · Mehmet Emir Çevik · Sehnaz Evrimler · Ihsaniye Suer Dogan — Febrero 26th 2026 at 15:00

by Ece Zengin, Aybuke Ucgun, Mehmet Emir Çevik, Sehnaz Evrimler, Ihsaniye Suer Dogan

Background

Epicardial adipose tissue (EAT) is associated with cardiometabolic disorders such as diabetes mellitus (DM), hyperlipidemia, and nonalcoholic fatty liver disease. However, its potential relationship with pancreatic steatosis and pancreatitis remains unclear, and existing studies offer inconsistent findings. Therefore, a clearer understanding of whether EAT reflects broader systemic ectopic fat burden or inflammatory processes is needed.This study evaluated the relationships between EAT thickness and DM, hyperlipidemia, hepatosteatosis, pancreatic steatosis, and pancreatitis.

Methods

This retrospective, single-center study included 200 patients who underwent abdominal CT between 2022 and 2024. EAT thickness was measured at the mid-RCA and LAD levels, and subcutaneous fat was measured at the umbilical level. Liver and pancreatic steatosis were assessed with CT or MRI. Demographic and clinical data (age, gender, LDL cholesterol, diabetes, and history of pancreatitis) were collected. Mann-Whitney U, Spearman correlation, and logistic regression were used in analyses; p  Results

Of the 200 patients, 31.4% had diabetes, 42% had hepatosteatosis, and 73.5% had a history of pancreatitis. EAT and subcutaneous fat were significantly higher in women at all levels (p  Conclusions

EAT thickness is significantly associated with DM, LDL cholesterol, pancreatitis history, and age, supporting its role as a potential imaging biomarker of cardiometabolic risk. These findings suggest that EAT may serve as an imaging marker of broader metabolic and inflammatory burden, supporting its relevance for cardiometabolic risk assessment.

MEPs elicited by multidirectional rotational-field TMS show marked differences compared to unidirectional Figure-of-8 and H7 coils

by Orit Wonderman Bar Sela, Shay Ofir Geva, Gaby S. Pell, Yiftach Roth, Jason Friedman, Afnan Muhana, Silvi Frenkel-Toledo, Nachum Soroker

Unidirectional transcranial magnetic stimulation (udTMS; e.g., via Figure-of-8 coil) depolarizes mainly neurons whose axonal orientation aligns with the direction of the induced electric field. A novel dual H-coil (T360°) TMS system (BrainsWayTM, Israel) generates a rotational magnetic field aimed to recruit a larger neuronal population by induction of a multidirectional electric field (rfTMS). This study aimed to comparatively assess the neurophysiological properties of motor evoked potentials (MEPs) elicited from the first dorsal interosseous (FDI) muscle following udTMS (via Figure-of-8 and H7 coils) vs. multidirectional rfTMS. In this study, 10 healthy adult subjects received TMS via the three coil configurations in a random order. The results showed that rfTMS elicited larger MEPs at a lower resting motor threshold (rMT) compared to the unidirectional coils. These findings suggest that rfTMS is likely to recruit larger populations of neurons compared to conventional udTMS coil configurations. This may be advantageous in efforts to enhance motor recovery following brain damage by treatments using TMS.

Exploring the drivers of price variation in orthopaedic radical bone tumor resection: A nationwide database study

by Devika A. Shenoy, William C. Cruz, Shamik Bhat, Katelyn Parsons, Aaron D. Therien, Kevin A. Wu, Christian A. Pean, William C. Eward

Background

Radical resection of bone tumors is a clinically effective but costly procedure. Despite the implementation of federal price transparency mandates, little is known about the nationwide variation in negotiated prices for these specialized oncologic surgeries. This study aimed to quantify the variation in negotiated rates for radical resection of the humerus and femur/knee and identify associated hospital, payor, and state-policy drivers.

Methods

This cross-sectional study analyzed hospital-negotiated payor rates from the Turquoise Health database for current procedural terminology (CPT) codes 24150 (humerus resection) and 27365 (femur/knee resection). Multivariate linear regression was used to determine the associations between hospital size and type, payor class, and state-level policies (Medicaid expansion, Certificate of Need [CoN] laws, All-Payer Claims Database [APCD] mandates, and Nurse Practitioner [NP] scope of practice) on negotiated payor rates.

Results

A total of 285,857 negotiated rates were analyzed. Significant price variation was observed across all factors. Large hospitals (>1000 beds) and Critical Access Hospitals (for femur/knee resection only) had significantly higher rates. CoN laws were associated with higher prices for both procedures (+$348.25 and +$667.98, respectively), as were APCD mandates for femur/knee resections (+$1231.24). Medicare Advantage plans paid inconsistently compared to commercial plans, paying more for humerus but substantially less for femur/knee resections.

Discussion

Negotiated prices for radical bone tumor resection are highly variable and influenced by a complex interplay of market dynamics, challenging the assumption that price transparency alone can standardize healthcare costs for specialized care.

Spatial heterogeneity and spatially varying determinants of childhood stunting in Northern Rwanda: A cross-sectional study to inform targeted interventions

by Clarisse Kagoyire, Albert Ndagijimana, Gilbert Nduwayezu, Jean Nepo Utumatwishima, Jean Pierre Mpatswenumugabo, Marie Anne Mukasafari, Diane Rinda, Vedaste Ndahindwa, Kristina Elfving, Gunilla Krantz, Torbjörn Lind, Ali Mansourian, Renée Båge, Ewa Wredle, Elias Nyandwi, Aline Umubyeyi, Jean Baptiste Ndahetuye, Petter Pilesjö

Despite national progress, stunting remains prevalent in specific regions of Rwanda, highlighting the limitations of coarse-resolution data for effective mapping and intervention planning. This study explored optimal spatial resolution and analytical approach to capture localised dynamics and the multifactorial nature of stunting. A cross-sectional, population-based study was conducted in the Northern Province of Rwanda, focusing on children aged 1–36 months. Data were collected using structured questionnaires covering socio-demographic, economic, health, childcare, livestock factors and anthropometric measurements. Environmental characteristics were obtained from national datasets, while household geographic coordinates were captured using a customized mobile geodata platform (emGeo). After data cleaning, predictors were analysed using univariable and multivariable logistic regression as well as geographically weighted logistic regression (GWLR) to account for spatial heterogeneity. Among 601 children, stunting prevalence was 27% (boys 33.8%; girls 20.9%). GWLR improved model fit, increasing adjusted deviance explained from 34% to 39%. Significant predictors included child age (adjusted OR = 2.46; 95% CI: 1.78–3.39), male sex (OR = 2.83; 95% CI: 1.65–4.86), birthweight (OR = 0.71; 95% CI: 0.54–0.94), maternal autonomy (ability to refuse sexual intercourse; OR = 0.48; 95% CI: 0.27–0.86), inconsistent maternal social support (OR = 2.30; 95% CI: 1.20–4.42), household electricity access (OR = 0.48; 95% CI: 0.27–0.84) and handwashing facilities (OR = 0.21; 95% CI: 0.07–0.67). GWLR revealed substantial spatial heterogeneity in these factors, delineating areas where each factor matters most. This household-level, spatially explicit analysis reveals localised risk patterns often masked by aggregated national data. Prioritising context-specific interventions (such as electrification, hygiene promotion, and enhanced maternal social support), can enhance effectiveness. The proposed analytical workflow provides a model for addressing persistent stunting in other resource-limited settings.

Evaluation of usability and acceptability of a Peruvian telemental health service for early assessment among vulnerable occupational workers: Mixed-method study with a user-centered design approach

by Jimmy Andreyvan Cainamarks-Alejandro, Liliana Cruz-Ausejo, Miguel Angel Burgos-Flores, Jaime Rosales-Rimache, Jonh Astete-Cornejo, David Villarreal-Zegarra

Background

The COVID-19 pandemic marked an increase in depressive, anxiety, and post-traumatic stress disorder symptoms, more specifically among healthcare workers, teachers, and police officers. These workers face external and occupational factors which had a significant impact on mental health, significant increase in workload and direct exposure to the virus, shortage of personnel protective equipment, and instances of abuse, including discrimination. Mental health care in primary care requires a process of early identification and timely referral of complex cases. Telehealth emerges as an effective alternative for addressing challenges in mental health care, although its implementation encounters obstacles.

Objective

To design a telehealth service that facilitates screening, initial management, and timely referral for mental health diagnoses in workers with prior SARS-CoV-2 infection, and to evaluate usability, acceptability, and user satisfaction.

Methods

Mixed-method study with a user-centered design approach involving key external and internal service users in three sequential stages (pre-design, co-design, and post-design). The study phases lasted 6 months, involving a total of 23 participants in the pre-design phase (contextual inquiry and preparation and training), 12 participants in the co-design phase (framing the issue, generative design, and sharing design), and in the post-design phase, 4 participants were involved in service implementation, and 81 participants—drawn from the subgroup of 134 users who received psychoeducation—were included in the efficacy assessment.

Results

The proposal included the development and evaluation of a service model guide and a telehealth software platform. First, the participants took part in a series of workshops (Pre-design, Co-design) where they provided ideas for meeting the product requirements, based on the Design Thinking methodology framework. The telehealth service model was named TelePsico CENSOPAS. It comprised four processes: a) Service promotion; b) User pre-identification; c) Appointment management; d) Psychoeducation counseling and referral. The Telehealth platform was designed through three cycles of an iterative process and integrated a proprietary development platform with third-party service technologies for communication support and information exchange. During post-design, the pilot test involved 698 screened patients; 193 were identified with mental health risks, and 134 of them received psychoeducation sessions. In addition to user acceptance, the usability score of the platform was 86.1 ± 16.9 SD, satisfaction dimensions of the service was 45.1 ± 7.2 SD for satisfaction with care processes, and 36.7 ± 5.2 SD satisfaction with psychological care.

Conclusion

The proposal for mental health telehealth services and its supporting platform was successfully developed and accepted by both internal and external users, particularly within well-structured occupational health services in workplaces serving vulnerable occupational groups. In addition, it achieved higher satisfaction and usability scores than Peru’s outpatient care services. These findings support the replicability of user-centered design frameworks—such as design thinking—within the occupational health sphere.

Por: Yaosen Du · Yiyong Yang · Xiaolong Wu · Pengju Gao · Hanchen Ma — Febrero 26th 2026 at 15:00

by Yaosen Du, Yiyong Yang, Xiaolong Wu, Pengju Gao, Hanchen Ma

To enhance the efficiency, safety, and data accuracy of drilling engineering, this study developed an integrated business management platform for drilling engineering grassroots units based on the Business Model Driven (BMD) approach. The platform is built on a “five horizontal, three vertical” cloud computing architecture, establishing a five-layer system from the infrastructure layer to the user layer horizontally, and supported by standard specifications, safety, and maintenance systems vertically, enabling collaboration across multiple business scenarios and data integration. Currently, four major modules with over 20 functionalities have been developed, supporting applications such as task coordination, engineering supervision, data analysis, and accident handling. Operational results demonstrate that the platform effectively promotes integrated management of drilling engineering through real-time data sharing, full-process quality control, and intelligent decision-making, thereby enhancing operational quality and safety, reducing accident risks, and providing critical technological support for the digital transformation and upgrading of the drilling industry.

Mapping of sex work hotspots to guide targeted HIV prevention: Evidence from eight Ukrainian cities

Por: Oksana Kovtun · Olga Cheshun · Oksana Pashchuk · Kostyantyn Dumchev — Febrero 26th 2026 at 15:00

by Oksana Kovtun, Olga Cheshun, Oksana Pashchuk, Kostyantyn Dumchev

Background

Ukraine’s HIV epidemic remains concentrated among key populations, with sex workers (SWs) facing overlapping vulnerabilities, including a history of injection drug use. Although overall HIV prevalence has declined, prevention coverage remains below national and global targets. Accurate mapping of sex work hotspots is essential for effective outreach, yet existing data are fragmented and incomplete, especially in privatized and digitally mediated environments. This study aimed to systematically identify and characterize sex work venues across eight Ukrainian cities and assess their coverage by HIV prevention services.

Methods

In 2021, we conducted a two-stage, multi-informant mapping study across eight Ukrainian cities, interviewing 1,212 secondary and 2,277 primary key informants, including SWs. Hotspots were characterized by type, perceived safety, access modality, operating schedule, and presence of SW subgroups. We used descriptive statistics, exploratory factor analysis, and multivariable mixed-effects regression to identify factors associated with HIV prevention service coverage.

Results

Of 2,581 identified hotspots, 2,118 (82.1%) were validated as active. Apartments (43.2%), virtual platforms (11.7%), and street-based sites (11.1%) were the most common. Only 13.7% of hotspots were registered in the national HIV service registry, while 34.1% received prevention service delivery and 18.9% were reached by mobile vans. Coverage was highest at street-based and office-type venues and consistently lowest in private, virtual, and pimp-mediated settings. Service coverage was positively associated with 24/7 or daytime operation, higher perceived safety, open access, and the presence of SWs who inject drugs.

Conclusions

This study provides comprehensive mapping of sex work hotspots in Ukraine, revealing persistent gaps in HIV prevention for less visible and harder-to-reach SWs. Community-led mapping achieved high validation rates (86.8%) and identified substantial unmet needs in digital and concealed hotspots. Routine hotspot mapping, combined with engagement with SW communities, is essential for data-driven, equitable, and adaptive HIV responses in rapidly changing contexts.

Purpose

This study outlines the changes in the age- and sex-specific burden of motor neuron disease (MND) in China from 1990 to 2021, focusing on the prevalence, incidence, number of disability-adjusted life years and mortality. Additionally, these trends are evaluated in comparison to the Global Burden of Disease data.

Methods

Public data from the Global Burden of Disease database covering the period from 1990 to 2021 were analyzed to explore the burden of motor neuron disease in China and worldwide. Trends in prevalence, incidence, disability-adjusted life years (DALYs) and mortality were examined in the analysis. The average annual percentage change was calculated using Joinpoint, and the relevant 95% confidence intervals (95% CIs) were examined to identify changes in the MND burden over time. Additionally, a thorough comparative analysis was performed to investigate the differences in the MND burden between China and other regions worldwide, considering factors such as age, sex, and time periods.

Results

From 1990 to 2021, the age-standardized incidence rate (ASIR) of motor neuron disease (MND) in China declined from 0.65 per 100,000 to 0.46 per 100,000, whereas the global ASIR decreased slightly from 0.81 per 100,000 to 0.77 per 100,000. In contrast, the age-standardized prevalence rate (ASPR) in China increased from 2.131 per 100,000 to 2.298 per 100,000, whereas the global ASPR decreased slightly from 3.356 per 100,000 to 3.31 per 100,000. The age-standardized mortality rate (ASMR) in China increased from 0.151 per 100,000 to 0.181 per 100,000; the global ASMR also increased from 0.38 per 100,000 to 0.46 per 100,000 during this period. Moreover, the age-standardized disability-adjusted life year (ASDR) rate in China decreased slightly from 7.995 per 100,000 to 7.672 per 100,000, whereas the global ASDR increased from 11.221 per 100,000 to 12.167 per 100,000. The average annual percentage changes (AAPCs) for the ASPR, ASIR, ASDR, and ASMR in China were −1.10%, 0.25%, 0.57%, and −0.14%, respectively. In contrast, the global AAPCs were −0.16%, −0.04%, 0.58%, and 0.26%, respectively. Age and sex played distinct roles in shaping MND burden. The ASIR of MND decreased but then increased for both sexes, remaining higher for males. Its ASPR trends differed: a slight increase in males versus an increase then decrease in females. While the ASMR was consistently higher for males, the DALYs for males started to decrease but surpassed those for females. Global MND rates have remained stable.

Conclusion

The prevalence, incidence, DALYs and mortality of motor neuron disease in China decreased between 1990 and 2021, suggesting a relative decrease in the total burden of MND in the country. Age influences the burden of MND, with a higher occurrence incidence in children and middle-aged individuals; the prevalence of MND is highest in the younger population, whereas MND-related mortality is the highest within the middle-aged and senior populations. Compared with females, males are more likely to be affected by MND and have a greater likelihood of death. Given the rapid population aging in China, MND is expected to remain a significant public health issue.

Effects of tacrolimus treatment on the gut microbiota and metabolites in liver transplant recipients

Por: Guohui Wang · Lu Liu · Hanshu Zhang · Panpan Mao · Saijuan Lu · Xiaofang Zhang · Xingde Li · Cangsang Song — Febrero 26th 2026 at 15:00

by Guohui Wang, Lu Liu, Hanshu Zhang, Panpan Mao, Saijuan Lu, Xiaofang Zhang, Xingde Li, Cangsang Song

Background

Liver transplantation (LT) is an effective treatment for patients with end-stage liver disease. In recent years, more and more evidence has supported the association between gut microbiota dysbiosis and the pathogenesis and progression of liver diseases.

Methods

The study included 36 patients who received tacrolimus treatment after liver transplantation. Patients were stratified into subgroups according to three key variables: tacrolimus treatment duration, whole-blood tacrolimus concentration, and tacrolimus concentration-to-dose (C/D) ratio. Fecal samples and whole-blood specimens were collected from all participants. The Illumina HiSeq X platform was used to detect the gut metagenome, analyzing the composition and characteristics of the gut microbiota. Liquid chromatography-tandem mass spectrometry (LC-MS/MS) technology was employed to detect metabolites of the gut microbiota, revealing their metabolic profiles.

Results

As the duration of tacrolimus use increased, the diversity of the gut microbiota also increased, and the abundance of Escherichia coli_D and Bacteroides stercoris rose. Additionally, the abundance of Brunovirus and Uetakevirus tended to decrease. The abundance of gene functions related to chemical carcinogenesis and bacterial invasion of epithelial cells significantly decreased. In the gut microbiota metabolites, 16 substances like Astragaloside A and Acetyl-L-carnitine significantly increased, while 108 substances like Capsaicin and TLK significantly decreased. Within a certain range, as the concentration of tacrolimus in whole blood increased, the diversity of the gut microbiota increased. The abundance of Phocaeicola and Klebsiella increased, and the abundance of Peduovirus among viruses also rose. However, excessively high concentrations may lead to a decrease in the diversity of the gut microbiota and a decrease in the abundance of Phocaeicola. With respect to the C/D ratio, increased ratios were linked to significantly higher levels of 57 fecal metabolites (e.g., PC 34:2, 5-Methyl-2’-deoxycytidine), whereas 13 metabolites (e.g., FAHFA 2:0/16:0) showed substantial declines.

Conclusions

Tacrolimus treatment is associated with distinct alterations in gut microbiota and metabolites among LT recipients. These findings provide a preliminary framework for future investigations aimed at optimizing immunosuppressive regimens, although their clinical translational potential requires validation in larger-scale, prospective cohort studies.

Attenuating effects of inflammatory pathway by prolonged left ventricular unloading after myocardial infarction in male rats

Por: Jingwen Gao · Yasushige Shingu · Ryota Azuma · Satoru Wakasa — Febrero 26th 2026 at 15:00

by Jingwen Gao, Yasushige Shingu, Ryota Azuma, Satoru Wakasa

Background

Inflammatory response plays a pivotal role in myocardial injury and post-infarction remodeling after acute myocardial infarction (AMI). Mechanical unloading (UL) of the left ventricle (LV) has been proposed as a potential therapeutic strategy to preserve cardiac function; however, its effects on myocardial inflammation remain incompletely understood.

Methods

We employed a rat model of partial UL using heterotopic heart-lung transplantation following AMI. RNA sequencing (RNA-seq) was performed to evaluate transcriptomic changes, with a specific focus on inflammatory pathways in the non-infarcted remote area. Immune cell abundance was estimated using deconvolution analysis (QUANTISEQ). Quantitative PCR was performed to analyze some inflammatory cytokines, and macrophage polarization was evaluated by immunohistochemistry.

Results

AMI significantly impaired cardiac function, which was mitigated by UL. RNA-seq analysis revealed marked activation of inflammatory pathways and identified several hub genes involved in cytokine signaling following AMI, while these transcriptional changes were not significantly altered in UL groups after AMI. Immune cell profiling demonstrated an increase in M2 macrophages after AMI, while UL preserved M2 macrophage levels. Histological analysis further supported UL’s modulatory effect on macrophage polarization. Pro-inflammatory cytokines TNFα and IL1β were upregulated after AMI but showed attenuation with UL.

Conclusion

Partial UL potentially attenuates cardiac functional deterioration after AMI while exerting substantial effects on inflammatory gene expression and macrophage polarization. These findings suggest that the cardioprotective effects of UL may be correlated with the modulation of inflammatory pathways in the remote area after AMI.

Factors associated with low levels of resilience among French university students during COVID-19 lockdown: results of the cross-sectional PIMS-CoV19 survey

Por: Todorovic · A. · Baumann · C. · Tarquinio · C. · Rotonda · C. · Rousseau · H. · Bourion-Bedes · S. — Febrero 26th 2026 at 13:47
Objectives

To identify the factors associated with low psychological resilience among university students in the Grand Est region of France at the end of the first national COVID-19 lockdown.

Design

A cross-sectional online survey was conducted (May 2020) among students at the University of Lorraine using the LimeSurvey platform and institutional mailing lists.

Setting

Higher education setting in north-eastern France, involving students from the University of Lorraine (multicampus public university) and Sciences Po Nancy, a political science institute in the same region.

Participants

A total of 3708 students fully completed the online questionnaire, including the Brief Resilience Scale (BRS), resulting in an estimated response rate of 7.1%. All students enrolled at the University of Lorraine and Sciences Po Nancy during the 2019–2020 academic year were eligible to participate.

Primary and secondary outcome measures

The primary outcome was psychological resilience, measured using the BRS. Secondary measures included perceived social support assessed with the Multidimensional Scale of Perceived Social Support, quality of interpersonal relationships evaluated using the Quality of Interpersonal Relationships Scale (Échelle de la Qualité des Relations Interpersonnelles, EQRI) and frequency of positive and negative thoughts measured with the Thermometer of Thoughts Tool. Factors associated with low resilience were analysed using bivariable and multivariable logistic regression.

Results

Among 3708 students included in the sample, corresponding to a response rate of approximately 7.1%, 50.6% had normal resilience, while 37.3% reported low resilience. Female gender (OR=2.1, 95% CI: 1.8 to 2.6) and low social support (OR=1.7, 95% CI: 1.1 to 2.6) were the factors associated most strongly with low resilience. Negative thoughts (OR=1.4, 95% CI: 1.4 to 1.5), lower quality of relationships with people in general (OR=1.5, 95% CI: 1.3 to 1.8) and studying arts, humanities or languages (OR=1.4, 95% CI: 1.0 to 1.8) were identified as factors associated with low resilience. Increased age (OR=0.9, 95% CI: 0.9 to 1.0) and flat sharing (OR=0.6, 95% CI: 0.4 to 0.9) were inversely associated with low resilience levels.

Conclusions

Resilience seems to be impacted primarily by internal and micro-environmental factors. Consolidating levels of individual resilience of at-risk populations by acting on these factors could be the key to improving their mental health.

Study protocol for a randomised controlled trial to evaluate the prophylactic efficacy of combined intense pulsed light (IPL) and low-level light therapy (LLLT) in preventing laser corneal refractive surgery-induced dry eye: the Treat Eye Before Laser ind

Por: Kerkouri · S. · Garcin · T. · Cochener · B. — Febrero 26th 2026 at 13:47
Introduction

Laser corneal refractive surgery is a widely adopted approach for correcting refractive errors, but postoperative dry eye remains a common side effect. Intense pulsed light (IPL) and low-level light therapy (LLLT) are two emerging treatments that have shown potential in managing dry eye disease. However, their role as a prophylactic treatment in patients without pre-existing symptomatic dry eye undergoing refractive surgery has not been explored.

Methods and analysis

This is a single-blind, randomised controlled trial comparing the prophylactic efficacy of combined IPL and LLLT treatment versus standard care in preventing dry eye after laser corneal refractive surgery (FS-LASIK, SMILE or PRK). Eligible patients aged 18 or older scheduled for surgery will be randomly assigned in a 1:1 ratio to either the treatment or control group. The primary endpoint is the French version of Ocular Surface Disease Index score at 1 month postoperatively. Secondary outcomes include Fluorescein Break-Up Time, Schirmer I test, Oxford score and Meibomian Gland Dropout. Data will be analysed using a mixed-effects linear model adjusted for surgery type and baseline dry eye parameters. The study started in June 2023 and end in April 2025 but data have not been yet analysed.

Ethics and dissemination

The study has been approved by the Institutional Review Board Est III, France, and registered on ClinicalTrials.gov (NCT05803798). All participants will provide written informed consent. Results will be disseminated through peer-reviewed publications and presentations at scientific conferences.

Trial registration number

NCT05803798.

Relationship between the urinary albumin-to-creatinine ratio and cardiovascular adverse outcomes in the Beijing community population: a prospective cohort study

Por: Liu · S. · Jia · J. · Huo · Y. · Fan · F. · Zhang · Y. — Febrero 26th 2026 at 13:47
Objectives

To investigate the correlation between the urinary albumin-to-creatinine ratio (UACR) and adverse cardiovascular outcomes in the Beijing community population.

Design

Prospective cohort study.

Setting

Beijing, China, from May 2014 to December 2021.

Participants

Recruited from a survey conducted as part of an ongoing atherosclerosis cohort study in the communities of Gucheng and Pingguoyuan, Shijingshan District in Beijing, China. Excluded participants who already had a history of stroke or myocardial infarction at baseline. Finally, 3627 eligible participants were included in this analysis.

Exposure

The participants were divided into three groups on the basis of baseline UACR: the normal group (UACR

Primary and secondary outcome measures

The primary endpoint was a composite endpoint (major adverse cardiovascular event, MACE) of cardiovascular death, first acute myocardial infarction or first stroke, whereas secondary endpoints included cardiovascular death, first acute myocardial infarction, first stroke or all-cause death.

Results

The study included 3627 participants. According to the multivariable Cox model, compared with those in the normal group, the risks of MACE (HR=1.47; 95% CI 1.06 to 2.06; p=0.023), cardiovascular death (HR=3.03; 95% CI 1.56 to 5.88; p=0.001) and all-cause mortality (HR=1.91; 95% CI 1.23 to 2.97; p=0.004) were significantly greater in the microalbuminuria group. The risk of MACE (HR=3.65; 95% CI 2.14 to 6.23; p

Conclusions

This study indicates that an elevated UACR is a significant risk factor for adverse cardiovascular outcomes within the community population. This association remains consistent in individuals with low-grade albuminuria.

Disparities in adverse event perception between patients and healthcare providers in gynaecologic anticancer therapy: results from an observational web-based study in Japan

Por: Hashimoto · H. · Soejima · A. · Nishimura · Y. · Ike · A. · Sugawara · M. · Shimada · M. · Abe · M. — Febrero 26th 2026 at 13:47
Objective

To explore patients’ perceptions of managing adverse events (AEs) from anticancer drugs for gynaecological cancer, focusing on AEs they want to avoid, views on dose adjustments and communication with healthcare professionals.

Design

Observational study using a web-based questionnaire.

Participants

Women in Japan who had received chemotherapy for endometrial or ovarian/fallopian tube cancer were enrolled. Healthcare professionals, including obstetrics and gynaecology physicians, nurses and pharmacists, who administered chemotherapy to these patients, were also enrolled.

Outcome measures

AEs that patients wished to avoid or found distressing; varied perceptions of AEs before and after treatment; discrepancies in the communication of AEs between patients and healthcare professionals; administration time and intervals between hospital visits patients found distressing; patient awareness of dose adjustment (reduction, interruption or discontinuation) to suppress AEs.

Results

Participants comprised 153 physicians, 166 nurses, 154 pharmacists and 154 patients. Nausea/vomiting (28.6%), alopecia (18.2%) and peripheral neuropathy (9.1%) were the most distressing AEs overall. Physicians rated nausea/vomiting lower (15.4%) and alopecia higher (38.2%) than patients, while pharmacists emphasised peripheral neuropathy (25.7%). Many patients found AEs, including peripheral neuropathy (53/99), fatigue (52/105) and alopecia (46/120), to be more severe than expected. Communication patterns revealed that 49.4% of patients reported all symptoms, even uncertain ones, but younger patients tended to communicate fewer symptoms. Physicians (54.2%), nurses (92.2%) and pharmacists (85.7%) preferred full disclosure of symptoms. While 28.6% of patients wished to avoid dose reductions because of fears of disease progression, 18.2% preferred dose reduction or discontinuation when AEs became intolerable. Drug administration times and visit intervals influenced patient distress. Treatment administration of over 3 hours (19.5%) and visits occurring more frequently than once every 3 weeks (27.3%) were the most distressing.

Conclusions

This study highlights discrepancies in AE perceptions and communication between patients and healthcare professionals, emphasising the need for tailored communication strategies and shared decision-making to improve cancer treatment experiences and outcomes.

Bridging the stroke care gap: development and validation of CaknaStrok Education Package (CEP) for caregivers of stroke survivors in Malaysia

Por: Sidek · N. N. · Kamalakannan · S. · Musa · K. I. · Long Tuan Kechik · T. S. M. · Hamzah · N. · Abd Hamid · R. I. · Darus · D. · Ibrahim · K. A. · Seman · N. · Ahamad Fouzi · L. · Abdul Hamid · F. · Ismail · T. A. T. — Febrero 26th 2026 at 13:47
Background

Stroke is one of the top causes of disability in Malaysia, yet caregivers have limited access to structured, culturally tailored education to support poststroke care.

Objectives

To develop and validate the CaknaStrok Education Package (CEP), a blended learning intervention comprising a printed guidebook and a trilingual mobile health application for informal stroke caregivers in Malaysia.

Design

Methodological study involving the development and validation of a caregiver education programme guided by the Analyse, Design, Develop, Implement, Evaluate (ADDIE) instructional design framework.

Setting

Development and validation were conducted in Malaysia between January 2022 and December 2023. Both experts and caregivers were recruited from two tertiary hospitals on the East Coast of Malaysia, with caregivers identified from inpatient wards and outpatient clinics at these hospitals.

Participants

Content validation involved 10 multidisciplinary experts. Face validation involved 14 informal stroke caregivers who met eligibility criteria, and all completed the study.

Methods

CEP was developed based on prior needs assessment and expert input. Content validation was undertaken using the Content Validity Index (CVI) and face validation using the Face Validity Index (FVI), both assessed on a four-point Likert scale. Qualitative feedback was also obtained from the participants.

Results

CEP consists of six modules delivered via a printed guidebook and a trilingual app with videos, assessment tools and local resources. Experts rated the content highly valid (Scale-level (S)-CVI/the average method (Ave): 0.97–0.99 across domains). Caregivers reported strong acceptability (S-FVI/Ave: 0.95–0.99). Qualitative feedback from experts and caregivers informed refinements to content clarity, usability and presentation, including improved navigation, consistent language use and enhanced visual design. Suggestions requiring substantial structural changes were documented for future iterations.

Conclusions

The CEP shows strong content and face validity as a blended caregiver education tool. By combining printed and digital formats, CEP addresses cultural and access challenges and provides a scalable model for stroke caregiver education in Malaysia. Further pilot or feasibility studies are warranted to evaluate usability, engagement and implementation in real-world settings prior to effectiveness evaluation.
