ABSTRACT

CDOM, an important ocean colour product, accounts for 90% of non-water UV absorption in the upper ocean. CDOM absorption triggers photochemical reactions resulting in the release of greenhouse gases and alters microbial bioavailability of organic matter. The three different approaches for retrieving a_dg(λ) from satellite data were validated using a_CDOM(λ) generated from OC-CCI-derived remote sensing reflectance (R_rs) and in situ measured a_CDOM(λ). The multiple linear regression (MLR) model performed better than the two exponential decay models in quantifying CDOM in the UV region. The better performance of R_rs-based algorithms indicated that absorption-based algorithms need considerable improvement when compared to algorithms based on the combined absorption by detrital matter and CDOM (a_dg(λ)). As a result, the absorption-based algorithm was modified as the ASCDOM algorithm, which demonstrated improved retrieval at 275, 355, 38 and 412 nm for a_CDOM(λ). The ASCDOM algorithm’s strong statistical performance highlights its accuracy in retrieving satellite products for water quality evaluations and ocean colour monitoring.

ABSTRACT

BACKGROUND: Digital vaccination campaigns are increasingly used to address declining vaccine confidence, yet evidence from large-scale, real-world interventions in middle-income countries is limited. Meta’s Brand Lift Studies (BLS), which use randomized test-control exposure, provide Bayesian esti-mates of attitudinal shifts resulting from digital content. Mexico, with over 88.6 million active internet users, provides a setting to evaluate the impact of targeted campaigns on vaccine atti-tudes.

OBJECTIVE: This study evaluated the impact of five digital vaccination campaigns implemented by the Aso-ciación Mexicana de Vacunología (@Vacunologia) on Facebook and Instagram in Mexico be-tween 2021 and 2022 on key attitudinal constructs related to COVID-19 vaccine confidence.

METHODS: This study used a retrospective ecological design, we analyzed aggregated BLS results for five campaigns targeting different audiences and vaccination themes. Measured outcomes included standard ad recall, perceived importance, perceived safety, perceived efficacy, and concerns about side effects. Statistical significance within the BLS framework was defined as an incre-mental lift of ≥2 percentage points with ≥90% posterior probability of replication-a threshold consistent with Meta’s operational Bayesian approach. Exploratory comparisons across cam-paigns were conducted using one-way analysis of variance (ANOVA), unpaired t-tests, and Fish-er’s Exact Tests.

RESULTS: Campaigns reached 84.9 million accounts and generated 179.4 million impressions with a total investment of USD 215,600. All campaigns produced statistically significant improvements in at least one attitudinal outcome (Bayesian threshold ≥90%). Standard ad recall increased in four campaigns (ANOVA, P < .001), and concerns about side effects decreased in two campaigns (t-test, P = .049; P = .006). Perceived safety, importance, and efficacy improved in selected audi-ences, with stronger effects observed among younger users and women (ANOVA, P = .005). No direct behavioral outcomes (eg, vaccination uptake) were measured; therefore, the findings reflect attitudinal rather than behavioral change. However, these constructs are recognized as proximal predictors of vaccine decision-making and constitute health-related outcomes.

CONCLUSIONS: Large-scale digital vaccination campaigns can meaningfully strengthen attitudinal determinants of vaccine confidence in a middle-income context. This social media advertising campaigns effec-tively increased standard ad recall and improved perceptions of vaccine importance and safety, particularly among younger audiences and women in urban areas. However, changes in efficacy perceptions and concerns about side effects were limited. The innovation and implications of this study lie in evaluating large-scale, real-world digital vaccine campaigns in Latin America using experimental BLS data. Findings highlight that audience segmentation yield stronger perceptual shifts, suggesting that tailored digital strategies can complement traditional public health com-munication. While BLS does not measure behavioral endpoints, the observed attitudinal im-provements represent foundational steps toward influencing vaccine-related behaviors. Future work should link digital attitudinal metrics with vaccination and epidemiological data to assess real-world health impact.

ABSTRACT

PURPOSE: To evaluate the safety and effectiveness of microfibrillar collagen paste (MCP), coils, and coils combined with gelatin sponge for transhepatic access tract embolization following portal vein islet cell transplant.

METHODS: A retrospective review was conducted at a single institution between January 2008 and October 2024, including 20, 28, and 21 consecutive islet cell transplant procedures requiring transhepatic access embolization with MCP, coils, and coil plus gelatin sponge, respectively. All procedures were performed via a right portal vein branch. MCP was performed using Avitene (BD). The average number of coils required in the coil plus gelatin sponge and coil-only groups were 1.8 and 1.6 coils per procedure, respectively. All patients were placed on therapeutic anticoagulation during the procedure and for at least two weeks post-transplant. Medical records were reviewed to compare laboratory results, portal venous pressures, post-procedure liver ultrasounds, and 30-day hemorrhagic events across the three groups.

RESULTS: All procedures were technically successful. However, one instance of coil migration into a portal vein branch occurred in the coil plus gelatin sponge group (1/28, 3.5%). Baseline hemoglobin, platelet counts, and partial thromboplastin time did not differ significantly between groups (p > 0.05). A statistically significant lower international normalized ratio (INR) was observed in the MCP group compared to the gelatin sponge and coil-only groups (1.0 vs. 1.1 vs. 1.1, p = 0.0036 and 0.004). No statistically significant differences were found in hemoglobin changes, post-transplant portal venous pressures, or post-embolization hemorrhagic events (p > 0.05). One patient in the coil plus gelatin sponge group developed a large subcapsular hematoma (1/27, 3.7%), while another in the MCP group experienced a large right hemothorax (1/20, 5.0%).

CONCLUSION: MCP, coils, and coil plus gelatin sponge are similarly effective for transhepatic access closure following islet cell transplant in anticoagulated patients. However, coil embolization may require multiple coils and carries a risk of migration.

ABSTRACT

Clinical practice guidelines on the optimal thromboprophylaxis duration following total hip and knee arthroplasty (THA and TKA) and hip fracture surgery are inconsistent. The aim of this meta-analysis is to investigate the effect of pharmacological prophylaxis duration on postoperative venous thromboembolism (VTE) in these patients. The primary outcome was the incidence of symptomatic and confirmed VTE at three months following surgery. A systematic search was performed in MEDLINE Complete (EBSCO), Embase, CINAHL complete (EBSCO), Web of Science and in CENTRAL databases, for randomised controlled trials comparing extended (minimum 28 days for THA and 10 days for TKA) vs. shorter duration thromboprophylaxis or placebo following these operations. Fifteen trials with a total of 26,580 participants were identified. Compared to shorter prophylaxis, extended thromboprophylaxis reduced 90-day symptomatic and confirmed VTE (OR: 0.43; 95% CI: 0.26-0.72; P = 0.001, I² = 0%; P = 0.75, respectively), significant only in the THA subgroup (P = 0.002). Beneficial effects were also observed with 30-day deep venous thrombosis (DVT) (OR: 0.32; 95% CI: 0.20-0.50; P < 0.001) and proximal DVT incidence (OR: 0.22; 95% CI: 0.12-0.41; P < 0.001) following THA. There were insufficient data to support extended prophylaxis for hip fracture surgery or TKA. Extending thromboprophylaxis up to 25-35 days appeared to reduce the incidence of 90-day symptomatic and confirmed VTE, particularly after THA. However, contemporary perioperative protocols, including early mobilisation and risk stratification, must be considered in determining optimal prophylaxis duration.

ABSTRACT

Despite ongoing efforts to reduce health disparities, substantial mortality differences persist across and within European countries. Avoidable mortality, i.e. deaths preventable through timely medical care or effective public health measures, provides a useful framework for assessing these inequalities. While previous studies largely focus on national differences, this study examines spatial differences and trends in avoidable mortality at the district level. We analysed official cause-of-death statistics for 581 districts across 10 European countries from 2002 to 2019, using age-standardised death rates (SDR) as the primary outcome. Spatiotemporal clusters were identified using emerging hotspot analysis. Our results show that SDRs for avoidable mortality declined across most districts for both sexes, yet marked disparities persist between men and women and between amenable and preventable mortality. Districts in Central and Eastern Europe consistently exhibited higher SDRs than those in Western and Southern Europe, while Germany occupies an intermediate position with particularly high rates for amenable mortality. Spatiotemporal hotspot analysis confirmed these patterns and showed that persistent high-mortality (hotspots) and low-mortality (coldspots) clusters persist, reflecting both substantial within-country inequalities and cohesive cross-border mortality patterns. These findings suggest that national boundaries are not always the most meaningful lines for explaining health outcomes. Instead, local socioeconomic and structural determinants of health play a central role. Persistent hotspots highlight areas where targeted interventions are urgently needed, while coldspots may offer lessons for best practices. Addressing these inequalities requires targeted, place-based, and transnational strategies to effectively reduce health inequalities in Europe.

ABSTRACT

Robotic surgery enables automated capture of objective performance indicators (OPIs), which reflect gestures at the surgeon consoles as well as activity at the patient cart. This systematic review evaluated associations between OPIs and clinical outcomes from robotic surgery. Across nine studies, OPIs were associated with various intra-operative and post-operative outcomes, including estimated blood loss, operative time, hospital stay, continence recovery, quality of life, and positive surgical margins. Studies involving predictive models demonstrated improved outcome prediction when combining OPIs with patient and disease characteristics compared to using clinical variables alone. These findings suggest that OPIs provide meaningful data in regard to surgical quality and patient outcomes. Further multicenter research across surgical specialties and robotic platforms is needed to validate the potential utility of OPIs in surgical training, benchmarking, and quality assessment.

ABSTRACT

BACKGROUND: Glioma is the most common primary brain tumor in adults, malignant progression and recurrence are inevitable. Although mechanisms of glioma development and progression have been demonstrated, the underlying driver pathway activation and the related therapeutic targets of recurrent gliomas, notably recurrent isocitrate dehydrogenase (IDH) wild-type gliomas, are rudimentary.

METHODS: We analyzed the differential expression genes (DEGs) between two subgroups of 80 IDH wild-type recurrent gliomas from the Chinese Glioma Genome Atlas (CGGA). We then constructed and validated an 11-gene signature based on cell cycle-related DEGs. SPSS and R languages ​​were used for statistical analysis and graphical work.

RESULTS: We proposed a molecular classification based on gene expression profiles and divided them into two subtypes that differed in their biological features and prognoses. We then constructed and validated an 11-gene signature based on cell cycle-related DEGs to better explore the association between cell cycle and tumor malignant progression. Additionally, the risk score could predict the sensitivity of patients to radiotherapy or chemotherapy. Functional analysis demonstrated that genes associated with the high-risk group were involved in various aspects of glioma cell cycle regulation. Moreover, the knockdown of SYCE2 blocked cell proliferation and improved cell sensitivity to temozolomide (TMZ).

CONCLUSION: This study developed a cell cycle-related signature for predicting the prognosis of recurrent IDH wild-type glioma, and identified a novel biomarker SYCE2, which could be used to assess the response of patients to TMZ.

ABSTRACT

Cancer-related fatigue is a common problem among colorectal cancer (CRC) survivors even after completion of treatment. In a randomized trial, we assessed the effect of a person-centred lifestyle program on cancer-related fatigue among CRC survivors who completed treatment.Survivors who completed treatment at least six months but no longer than five years ago, and who were experiencing cancer-related fatigue were randomized to intervention or control group. The intervention group worked with a lifestyle coach for six months during 12 sessions, to stepwise increase adherence to the World Cancer Research Fund/American Institute of Cancer Research cancer prevention guidelines on healthy diet and physical activity. Control group did not receive lifestyle coaching. Changes in cancer-related fatigue from baseline to six months were assessed with the FACIT-Fatigue Scale. As secondary outcome, we assessed changes in health-related quality of life (HRQoL). Higher scores indicate less fatigue and better HRQoL.80 participants were randomized to the intervention group; 81 to the control group. Baseline characteristics were similar: mean age 64.1±10.9 years, 55.3% women, 72% had colon cancer. There were favourable changes in dietary behaviours and physical activity in the intervention group; the control group did not show changes to the same extent. The program did not result in statistically significant differential changes over time between intervention and control group in cancer-related fatigue (0.8; 95%CI -1.6,3.2) or HRQoL (1.3; 95%CI -2.2,4.8).A person-centred lifestyle program improved lifestyle of CRC survivors, but the program was not effective in reducing cancer-related fatigue or in improving HRQoL.

ABSTRACT

BACKGROUND: Melasma is a common chronic hyperpigmentation disorder that substantially impairs patients’ quality of life. With the rapid growth of short-video platforms such as TikTok and Bilibili, an increasing number of patients are turning to these media for health-related information. This study aimed to evaluate the quality and reliability of melasma-related videos available on TikTok and Bilibili.

METHODS: Between August 17 and 19, 2025, we searched Douyin (the Chinese version of TikTok) and Bilibili using the Chinese keyword “” (“melasma”), and included the top 150 videos under each platform’s default comprehensive ranking. The search and analysis were conducted in Chinese, reflecting the linguistic and geographical context of mainland China. Video characteristics and engagement metrics were recorded. The quality and reliability of the videos were independently evaluated by two researchers using the Global Quality Score (GQS) and the modified DISCERN (mDISCERN) instrument.

RESULTS: A total of 237 videos were included in this study. Content was dominated by clinical manifestations (46.8%), etiology (44.3%), and diagnosis (40.1%), whereas treatment-related content was markedly underrepresented (9.7%). The median video length was 127.00 s (70.75-270.50) on Bilibili and 47.00 s (35.00-96.00) on TikTok. TikTok videos achieved significantly higher engagement than Bilibili (p < 0.05). Overall video quality was moderate, with both GQS and mDISCERN showing a median score of 3.00 (IQR: 2.00-4.00). The mDISCERN score of Bilibili videos was 3.00 (3.00-4.00), significantly higher than TikTok (p < 0.05). Videos uploaded by healthcare professionals scored 3.00 (3.00-4.00) on GQS and 3.00 (2.00-4.00) on mDISCERN, both significantly higher than those uploaded by non-healthcare professionals (p < 0.05).

CONCLUSIONS: This study found that melasma-related short videos presented an incomplete content structure, with treatment-related information being markedly underrepresented. The overall quality of the videos was moderate, whereas those produced by healthcare professionals demonstrated higher quality and reliability. Future efforts should encourage greater participation from healthcare professionals and the implementation of refined content strategies, with the aim of improving both the quality and educational value of dermatology-related short video resources.

ABSTRACT

Schizothorax richardsonii (Gray, 1832), commonly known as snow trout, is a widely consumed food fish in the cold-water drainages of the Himalayas and serves as a significant source of animal protein for communities living along the riverbanks. This study examined morphological and genetic variations in six stocks of S. richardsonii from the Ganga and Chenab river systems in the Central and Western Indian Himalayas, utilizing the truss network analysis and mitochondrial COX1 gene marker. A total of 268 fish samples were collected for morphometric analysis, of which 34 were used for genetic study, from six distinct locations between August 2021 and July 2022. Various statistical analyses were performed, including univariate analysis of variance (ANOVA), multivariate analysis of variance (MANOVA), principal component analysis (PCA), discriminant analysis of principal components (DAPC), canonical discriminant function analysis (CDFA) and boxplot analysis. Seventy-one morphometric measurements of fish showed statistically significant variations (p < 0.01) among six locations of the two river basins forming six different fish stocks. The origins of the dorsal, pectoral fins and eye diameter were found to be important parameters in morphological discrimination. Furthermore, sequencing and analysis of the mitochondrial COX1 gene of 34 specimens of S. richardsonii revealed the highest haplotype (0.80000) and nucleotide (0.00265) diversities in the Pindar River. A newly emerged haplotype, Hap_7, was identified in the Rajouri Tawi. Phylogenetic analysis showed clear geographical divergence among the populations. Canonical correspondence analysis (CCA) identified morphometric variations that were attributed to differences in water velocity and transparency of the selected drainages, whereas genetic variations were associated with differences in water temperature, prolonged geographical isolation, geological changes and reproductive isolation between populations. Our study provides a comprehensive understanding of the morphometric and genetic population structure and evolutionary dynamics, which will help resolve the taxonomic ambiguity and suggest potential population structure and indicate possible management units for this vulnerable species.
