RESUMEN
BACKGROUND: Cambodia's health sector faces significant challenges exacerbated by aid fragmentation, where development aid is dispersed among numerous small, uncoordinated projects. This study examines the distribution of health sector aid among Cambodia's principal donors to identify priorities, overlaps, and potential collaboration opportunities, addressing the urgent need for aid efficiency and alignment with national health priorities. METHODS: Utilizing OECD datasets and the Herfindahl-Hirschman Index (HHI) for the years 2010-2021, this study quantifies aid fragmentation within Cambodia's health sector. It analyzes aid allocations from the top five donors-United States, Australia, South Korea, Japan, and Germany-across various health projects and initiatives, evaluating the extent of fragmentation and identifying areas for potential donor collaboration. RESULTS: This study's findings highlight a pervasive issue of aid fragmentation within Cambodia's health sector, evident through the sector's low HHI score. This indicates a widespread distribution of aid across numerous small-scale initiatives, rather than targeted, unified efforts. A notable example includes Japan and Korea, which exhibit lower HHI scores, indicating a more pronounced fragmentation in their aid allocation. These countries' contributions are spread across various sectors without a dominant focus, contrasting with the United States' significant dedication to infectious disease control. However, beyond this specific area, the US's aid distribution across other priority health areas shows signs of fragmentation. This scattered approach to aid allocation, even amidst instances of focused support, illustrates the overarching challenge of aligning donor contributions with the holistic needs of Cambodia's health infrastructure. CONCLUSIONS: This investigation highlights the critical need for enhanced collaboration and strategic harmonization among international donors to mitigate aid fragmentation in Cambodia's health sector. It underscores the importance of adopting integrated and priority-aligned aid strategies to improve the efficiency and impact of health aid. By fostering synergistic partnerships and harmonizing donor efforts, there is a potential to create a more cohesive support framework that resonates with Cambodia's comprehensive health requirements and contributes to sustainable health outcomes. Such harmonization not only aligns with Sustainable Development Goal 3 by optimizing health services and outcomes but also strengthens global partnerships under Sustainable Development Goal 17, fostering a unified approach to international development.

There are unacceptable racial inequities in perinatal outcomes in the United States. Social determinants of health (SDOH) are associated with health outcomes and contribute to disparities in maternal and newborn health. In this article, we (1) review the literature on SDOH improvement in the perinatal space, (2) describe the SDOH work facilitated by the Illinois Perinatal Quality Collaborative (ILPQC) in the Birth Equity quality improvement initiative, (3) detail a hospital's experience with implementing strategies to improve SDOH screening and linkage to needed resources and services and (4) outline a framework for success for addressing SDOH locally. A state-based quality improvement initiative can facilitate implementation of strategies to increase screening for SDOH. Engaging patients and communities with specific actionable strategies is key to increase linkage to needed SDOH resources and services.

Obesity requires treatment to mitigate the potential development of further metabolic disorders, including diabetes, hyperlipidemia, tumor growth, and non-alcoholic fatty liver disease. We investigated the anti-obesity effect of a 30% ethanol extract of Eisenia bicyclis (Kjellman) Setchell (EEB) on 3T3-L1 preadipocytes and high-fat diet (HFD)-induced obese C57BL/6 mice. Adipogenesis transcription factors including peroxisome proliferator-activated receptor (PPAR)γ, CCAAT/enhancer-binding protein-alpha (C/EBPα), and sterol regulatory element-binding protein-1 (SREBP-1) were ameliorated through the AMP-activated protein kinase (AMPK) pathway by EEB treatment in differentiated 3T3-L1 cells. EEB attenuated mitotic clonal expansion by upregulating cyclin-dependent kinase inhibitors (CDKIs) while downregulating cyclins and CDKs. In HFD-fed mice, EEB significantly decreased the total body weight, fat tissue weight, and fat in the tissue. The protein expression of PPARγ, C/EBPα, and SREBP-1 was increased in the subcutaneous fat and liver tissues, while EEB decreased the expression levels of these transcription factors. EEB also inhibited lipogenesis by downregulating acetyl-CoA carboxylase (ACC) and fatty acid synthase (FAS) expression in the subcutaneous fat and liver tissues. Moreover, the phosphorylation of AMPK and ACC was downregulated in the HFD-induced mouse group, whereas the administration of EEB improved AMPK and ACC phosphorylation; thus, EEB treatment may be related to the AMPK pathway. Histological analysis showed that EEB reduced the adipocyte size and fat accumulation in subcutaneous fat and liver tissues, respectively. EEB promotes thermogenesis in brown adipose tissue and improves insulin and leptin levels and blood lipid profiles. Our results suggest that EEB could be used as a potential agent to prevent obesity.

BACKGROUND: Maternal deaths resulting from opioid use disorder have been increasing across the United States. Opioid use disorder among pregnant persons is associated with adverse pregnancy outcomes, including preterm birth, along with racial disparities in optimal opioid use disorder care. OBJECTIVE: This study aimed to evaluate whether the Illinois Perinatal Quality Collaborative implementation of the Mothers and Newborns affected by Opioids - Obstetric quality improvement initiative was associated with improvement in opioid use disorder identification, provision of optimal opioid use disorder care for birthing patients, and reduction in racial gaps in optimal opioid use disorder care. STUDY DESIGN: Using a prospective cohort design, hospitals reported monthly key measures for all patients with opioid use disorder at delivery between July 2018 and December 2020. The Illinois Perinatal Quality Collaborative facilitates collaborative learning opportunities, rapid response data, and quality improvement support. Generalized linear mixed-effects regression models were used to evaluate improvement in optimal opioid use disorder care, including increases in linkages to medication-assisted treatment, recovery treatment services, and naloxone counseling across time, and to determine whether optimal opioid use disorder care was associated with positive outcomes, such as lower odds of preterm birth. RESULTS: A total of 91 hospitals submitted data on 2095 pregnant persons with opioid use disorder. For the primary outcomes, the rates of patients receiving medication-assisted treatment and recovery treatment services improved across the initiative from 41% to 78% and 48% to 67%, respectively. For the secondary outcomes, the receipt of recovery treatment services and both recovery treatment services and medication-assisted treatment provided prenatally before delivery admission was associated with lower odds of preterm birth (adjusted odds ratio: 0.67 [95% confidence interval, 0.50-0.91] and 0.49 [95% confidence interval, 0.31-0.75], respectively). During the first quarter of the initiative, Black patients with opioid use disorder were less likely to be linked to medication-assisted treatment than White patients (23% vs 48%, respectively); however, an increase in medication-assisted treatment rates across the initiative occurred for all patients, with the greatest improvement for Black patients with an associated reduction in this disparity gap with >70% of both Black and White patients linked to medication-assisted treatment. CONCLUSION: The Mothers and Newborns affected by Opioids - Obstetric initiative was associated with improvement in optimal opioid use disorder care for pregnant patients across Illinois hospitals, additionally racial disparities in opioid use disorder care was reduced across the initiative. Our findings implicate how optimal opioid use disorder care can improve pregnancy outcomes and close persistent racial gaps for pregnant individuals with opioid use disorder.
RESUMEN
Ni-rich layered oxides have received significant attention as promising cathode materials for Li-ion batteries due to their high reversible capacity. However, intergranular and intragranular cracks form at high state-of-charge (SOC) levels exceeding 4.2 V (vs. Li/Li+), representing a prominent failure mechanism of Ni-rich layered oxides. The nanoscale crack formation at high SOC levels is attributed to a significant volume change resulting from a phase transition between the H2 and H3 phases. Herein, in contrast to the electrochemical crack formation at high SOC levels, another mechanism of chemical crack and pit formation on a nanoscale is directly evidenced in fully lithiated Ni-rich layered oxides (low SOC levels). This mechanism is associated with intergranular stress corrosion cracking, driven by chemical corrosion at elevated temperatures. The nanoscopic chemical corrosion behavior of Ni-rich layered oxides during aging at elevated temperatures is investigated using high-resolution transmission electron microscopy, revealing that microcracks can develop through two distinct mechanisms: electrochemical cycling and chemical corrosion. Notably, chemical corrosion cracks can occur even in a fully discharged state (low SOC levels), whereas electrochemical cracks are observed only at high SOC levels. This finding provides a comprehensive understanding of the complex failure mechanisms of Ni-rich layered oxides and provides an opportunity to improve their electrochemical performance.
RESUMEN
Dietary fiber intake and physical fitness are independently associated with high-sensitivity C-reactive protein (hs-CRP) levels. Nevertheless, the association between dietary fiber intake, measures of physical fitness, and hs-CRP levels has not yet been fully evaluated. We investigated the influence of a combination of dietary fiber intake and measures of physical fitness, including hand grip strength, resistance training, and metabolic equivalents of tasks, on hs-CRP levels. Data collected from the Korea National Health and Nutrition Examination Survey (KNHANES) spanning 2015 to 2018 were used in this study. A total of 16,934 participants (7434 men and 9500 women aged ≥19 years) were included in this study. After adjusting for confounding factors (age, education, income, marital status, smoking status, drinking habits, total energy intake, and aerobic physical activity), we employed a multivariable logistic model to examine the association of dietary fiber intake and measures of physical fitness with hs-CRP levels. Among women, the odds of high hs-CRP levels were lower in those with the highest dietary fiber intake and superior grip strength compared to in women with the lowest dietary fiber intake and weaker grip strength (odds ratio [OR] = 0.40, 95% confidence interval [CI] = 0.24-0.68). The highest dietary fiber intake who participated in resistance exercise at least three times per week had a reduced odds of high hs-CRP levels compared with those with the lowest dietary fiber intake who did not engage in resistance exercise in both men and women (OR = 0.53, 95% CI = 0.32-0.89; OR = 0.40, 95% CI = 0.19-0.84, respectively). Our findings indicate that dietary fiber intake and high levels of physical fitness were associated with reduced odds of elevated hs-CRP levels.

PURPOSE: To evaluate the usefulness of ridge augmentation using a customized titanium mesh (CTM) that was preformed by trimming and bending the commercial titanium mesh on a virtually reconstructed 3D acrylic resin model using clinical, radiologic, histologic, and histomorphometric analyses. MATERIALS AND METHODS: This study was designed prospectively for patients who required vertical ridge augmentation using a staged approach before implant surgery. After installation of the CTM, grafting was performed using deproteinized porcine bone mineral covered with an absorbable membrane. Computed tomography was performed preoperatively and 6 months after simultaneous/staged guided bone regeneration to measure planned, reconstructed, and lacking bone volume, and the reconstruction rate was calculated based on these values. Clinical complications were also recorded, particularly the mesh exposure rate. At re-entry, the bone core was obtained using a trephine bur, and histologic and histomorphometric analyses were performed. RESULTS: A total of 10 sites in eight patients were used for the study analysis. The mean planned bone volume was 1.15 cm3 (range: 0.78 to 1.56 cm3), mean lacking bone volume was 0.13 cm3 (range: 0 to 0.59 cm3), and mean reconstructed bone volume was 1.02 cm3 (range: 0.56 to 1.43 cm3). The exposure rate was 30% (3 out of 10 sites). The reconstruction rate was over 80%, except for one case that showed suppuration. From histomorphometric analysis, 27.52% ± 16.87% of new bone, 7.62% ± 5.19% of residual graft, and 64.86% ± 23.76% of connective tissue were observed. The core biopsy samples demonstrated different pseudoperiosteum layer appearances based on the healing stage of the augmented sites. In the premature bone, the inner osteogenic layer consisted of multiple layers of osteoblast cells with adjacent large blood vessels. However, in the mature augmented site, there was no specific inner osteogenic layer, and the outer fibrous layer was dominant. CONCLUSIONS: The fabrication of CTM based on the application of the 3D-printing technique makes vertical ridge augmentation easier and can reduce complications and achieve target bone acquisition. In addition, it is expected that quantitative analysis of the pseudoperiosteum layer will be facilitated using the CTM.

BACKGROUND: Mpox is a viral illness with a characteristic skin rash caused by the monkeypox virus. In 2022, Mpox spread throughout the world, and an epidemic through domestic transmission started in South Korea in early 2023. This study aimed to summarize the clinical features of Mpox patients in South Korea. METHODS: This is a multicenter retrospective study conducted at four hospitals in South Korea. All adult patients diagnosed with Mpox who were admitted to the study hospitals between June 1, 2022 and May 26, 2023 and were discharged by June 30, 2023 were reviewed. RESULTS: Sixty patients were included, accounting for 65.9% of Mpox cases reported in South Korea during the study period. Median age was 32 years and 97% (58/60) of patients were male. In total, 85% (51/60) of patients reported their sexual orientation as homosexual or bisexual. The most common route of transmission was sexual or close contact (55/60). Every patient had a skin rash and 88% (53/60) had constitutional symptoms. In total, 42% (25/60) of patients had human immunodeficiency virus and 25% (15/60) had concomitant sexually transmitted infections. Severe manifestations of Mpox were identified in only two patients. CONCLUSION: Mpox patients in South Korea were mainly young adult males and were infected through sexual contact. The clinical outcomes were favorable.

Applying a drain bias to a strongly gate-coupled semiconductor influences the carrier density of the channel. However, practical applications of this drain-bias-induced effect in the advancement of switching electronics have remained elusive due to the limited capabilities of its current modulation known to date. Here, we show strategies to largely control the current by utilizing drain-bias-induced carrier type switching in an ambipolar molybdenum disulfide (MoS2) field-effect transistor with Pt bottom contacts. Our CMOS-compatible device architecture, incorporating a partially gate-coupled p-n junction, achieves multifunctionality. The ambipolar MoS2 device operates as an ambipolar transistor (on/off ratios exceeding 107 for both NMOS and PMOS), a rectifier (rectification ratio of â¼3 × 106), a reversible negative breakdown diode with an adjustable breakdown voltage (on/off ratio exceeding 109 with a maximum current as high as 10-4 A), and a photodetector. Finally, we demonstrate a complementary inverter (gain of â¼24 at Vdd = 1.5 V), which is highly facile to fabricate without the need for complex heterostructures and doping processes. Our study provides strategies to achieve high-performance ambipolar MoS2 devices and to effectively utilize drain bias for electrical switching.
RESUMEN
C/EBP homologous protein (CHOP) is a key regulator in ER stress-mediated signaling pathway via PERK-dependent unfolded protein response. It has been known that microRNA-616 (miR-616) is produced from the intron of the human DDIT3 gene encoding CHOP and increased by ER stress. However, the role of miR-616 and its targets are not fully addressed yet. Here we try to identify a novel target of miR-616 in human lung epithelial cells. Microarray analysis showed that CXCL5 is the most downregulated gene by miR-616 overexpression in A549 cells. We also found that CXCL5 mRNA and protein levels were significantly reduced by miR-616 mimic in the presence or absence of TNFα, while anti-miR-616 enhanced CXCL5 expression. In addition, miR-616-3p targeting sequence in 3'UTR of CXCL5 was confirmed by luciferase reporter assay suggesting that miR-616-3p directly binds to 3'UTR of CXCL5 and inhibits CXCL5 expression. Finally, we confirmed that conditioned medium from A549 cells treated with TNFα or Streptococcus pneumoniae lysates increased intra-alveolar neutrophil infiltration in a mouse model of pulmonary inflammation, while this induction was significantly reduced in a conditioned medium from cells transfected with miR-616-3p. These results suggest that miR-616-3p can alleviate CXCL5-induced pulmonary inflammatory response via targeting 3'UTR of CXCL5 gene.

Background: Methyl lucidone (ML), a methyl derivative of lucidone, has anti-inflammatory properties. However, the molecular mechanisms that reduce the inflammatory effect of ML in human lung epithelial cells remain unkown. This study aimed to elucidate the molecular mechanisms underlying the anti-inflammatory effect of ML. Methods: Four compounds (ML, methyl linderone, kanakugiol, and linderone) from Lindera erythrocarpa Makino were evaluated for their ability to reduce MUC5AC secretion levels in phorbol-12-myristate-13-acetate (PMA)-stimulated NCI-H292 cells using ELISA. The expression and secretion levels of inflammatory response-related proteins were analyzed using quantitative reverse transcription-PCR, ELISA, and western blotting. To determine whether ML directly regulates TGF-ß-activated kinase 1 (TAK1), we performed an in vitro kinase assay. Results: ML treatment effectively reduced the levels of inflammatory cytokines, including interleukin-1ß and TNF-α, increased by stimulation. Furthermore, ML downregulated the pathway cascade of both IκB kinase (IKK)/NF-κB and p38 mitogen-activated protein (MAP) kinase/CREB by inhibiting the upstream kinase TAK1. An in vitro kinase analysis confirmed that ML treatment significantly reduced the kinase activity of TAK1. Conclusion: ML pretreatment repressed the PMA-stimulated inflammation reaction by reducing the TAK1-mediated IKK/NF-κB and p38 MAP kinase/CREB signaling. These findings suggest that ML may improve respiratory health and can be used as a dietary supplement or functional food to prevent inflammatory lung diseases.
RESUMEN
OBJECTIVE: This study examines improvement in birth certificate accuracy during a statewide quality improvement initiative. STUDY DESIGN: Participating hospitals systematically sampled 10 delivery medical records per month and compared them to corresponding birth certificates for accuracy. Accuracy was computed before implementing the initiative (Aug-Oct 2014), end of phase 1 (July 2015) and end of phase 2 (Nov-Dec 2015). Accuracy data was aggregated and compared across time points using a linear mixed model and by hospital characteristics. RESULTS: 105 hospitals participated. Birth certificate accuracy increased between baseline (89.59%) and end of phase 2 (97.00%, p < 0.001). Percent accuracy at baseline was lowest in hospitals serving at-risk populations (p < 0.01). These hospitals showed relatively greater increases in overall accuracy with no difference in accuracy by the end of the initiative. CONCLUSIONS: A statewide QI effort contributed to improvements in birth certificate accuracy. Hospitals serving at-risk populations exhibited the greatest benefit and improvement.

We present a new type of torsional soft morphing actuator designed and fabricated by twisted shape memory alloy (SMA) wires embedded in polydimethylsiloxane matrix. The design and fabrication process of the proposed soft morphing actuator are presented with investigations of its working mechanism. Actuation performance was evaluated with respect to the temporal response, the maximum torsional deformation under an applied electric current, and various design parameters including the twist direction, wire diameter, helical pitch of the SMA wire, and the actuator's thickness and length. We demonstrate potential applications of the proposed soft morphing actuator as a soft morphing wing and airfoil. The proposed actuator will aid in the development of soft actuators, soft robotics, and other relevant scientific and engineering applications.
RESUMEN
Ischemia/reperfusion (IR) injury is an inevitable pathological event occurring when blood is resupplied to the tissues after a period of ischemia. One of major causes of IR injury is the overproduction of reactive oxygen species (ROS) including hydrogen peroxide (H2O2), which mediates the expression of various inflammatory cytokines to exacerbate tissue damages. The overproduced H2O2 could therefore serve as a diagnostic and therapeutic biomarker of IR injury. In this study, poly(boronated methacrylate) (pBMA) nanoparticles were developed as nanotheranostic agents for renal IR injury, which not only generate CO2 bubbles to enhance the ultrasound contrast but also provide potent preventive effects in a H2O2-triggered manner. The surface of pBMA nanoparticles was decorated with taurodeoxycholic acid (TUDCA) that binds P-selectin overexpressed in inflamed tissues. In the mouse model of renal IR injury, TUDCA-coated pBMA (T-pBMA) nanoparticles preferentially accumulated in the injured kidney and markedly enhanced the ultrasound contrast. T-pBMA nanoparticles also effectively prevented renal IR injury by scavenging H2O2 and suppressing the expression of inflammatory cytokines. Treatment progress of IR injury could be also monitored by echogenic T-pBMA nanoparticles. Given their targeting ability, excellent H2O2-responsiveness, anti-inflammatory activity and H2O2-triggered echogenicity, T-pBMA nanoparticles have excellent translational potential for the management of various H2O2-related diseases including IR injury.

Measuring, recording and analyzing spectral information of materials as its unique finger print using a ubiquitous smartphone has been desired by scientists and consumers. We demonstrated it as drug classification by chemical components with smartphone Raman spectrometer. The Raman spectrometer is based on the CMOS image sensor of the smartphone with a periodic array of band pass filters, capturing 2D Raman spectral intensity map, newly defined as spectral barcode in this work. Here we show 11 major components of drugs are classified with high accuracy, 99.0%, with the aid of convolutional neural network (CNN). The beneficial of spectral barcodes is that even brand name of drug is distinguishable and major component of unknown drugs can be identified. Combining spectral barcode with information obtained by red, green and blue (RGB) imaging system or applying image recognition techniques, this inherent property based labeling system will facilitate fundamental research and business opportunities.

Citrus cultivars have remarkable health benefits, but only the anti-inflammatory activities of the major varieties have been studied. This study investigated the anti-inflammatory effects of various citrus cultivars and their active anti-inflammatory components. The essential oils of 21 citrus peels were extracted via hydrodistillation using a Clevenger-type apparatus, and the chemical compositions of the essential oils were analyzed. D-Limonene was the most abundant constituent. To evaluate the anti-inflammatory effects of the citrus cultivars, the gene expression levels of an inflammatory mediator and proinflammatory cytokines were investigated. Among the 21 essential oils, those extracted from C. japonica and C. maxima exhibited superior anti-inflammatory activities, being able to inhibit the expression of the inflammatory mediators and proinflammatory cytokines in lipopolysaccharide-stimulated RAW 264.7 cells. The essential oils of C. japonica and C. maxima were distinguished into seven distinct constituents, α-pinene, myrcene, D-limonene, ß-ocimene, linalool, linalool oxide, and α-terpineol, compared with other essential oils. The anti-inflammatory activities of the seven single compounds significantly inhibited the levels of inflammation-related factors. In particular, α-terpineol exhibited a superior anti-inflammatory effect. This study showed that the essential oils from C. japonica and C. maxima exhibit high anti-inflammatory activity. In addition, α-terpineol is an active anti-inflammatory compound that contributes to inflammatory responses.
RESUMEN
Waning vaccine-induced immunity, coupled with the emergence of SARS-CoV-2 variants, has inspired the widespread implementation of COVID-19 booster vaccinations. Here, we evaluated the potential of the GX-19N DNA vaccine as a heterologous booster to enhance the protective immune response to SARS-CoV-2 in mice primed with either an inactivated virus particle (VP) or an mRNA vaccine. We found that in the VP-primed condition, GX-19N enhanced the response of both vaccine-specific antibodies and cross-reactive T Cells to the SARS-CoV-2 variant of concern (VOC), compared to the homologous VP vaccine prime-boost. Under the mRNA-primed condition, GX-19N induced higher vaccine-induced T Cell responses but lower antibody responses than the homologous mRNA vaccine prime-boost. Furthermore, the heterologous GX-19N boost induced higher S-specific polyfunctional CD4+ and CD8+ T cell responses than the homologous VP or mRNA prime-boost vaccinations. Our results provide new insights into booster vaccination strategies for the management of novel COVID-19 variants.

Although drugs such as acetaminophen, opioids, and nonsteroidal anti-inflammatory drugs (NSAIDs), are commonly used for pain management, the side effects of these drugs such as hepatotoxicity, nephrotoxicity, nausea, and vomiting, can not be neglected. Therefore, combinations of analgesics with different mechanisms raise the possibility of developing novel analgesics. Therefore, the aim of the present study was to evaluate whether DW-1021, the ionic complex of pelubiprofen (NSAID) and tramadol (opioid), has synergic antinociceptive and anti-inflammatory effects in nociceptive as well as inflammation-induced nociceptive models compared to pelubiprofen- or tramadol-only administration. Strong synergistic antinociceptive efficacy of DW-1021 was observed in the mouse writhing test and von Frey paw withdrawal threshold test in the carrageenan-induced rats. The hot plate test in mice and the Randall-Selitto mechanical paw pressure test in carrageenan-induced rats revealed that DW-1021 had a preferable effect on relieving pain to pelubiprofen, but not as much as tramadol. In the carrageenan-induced rats, DW-1021 had a more potent effect on reducing paw inflammation (paw volume, width, and thickness) via the suppression of PGE2 production than tramadol, but less than that of pelubiprofen. Taken together, our results suggest that the administration of DW-1021, a combination of pelubiprofen and tramadol, exerted a potent effect and can be used as a potential therapeutic agent for relieving pain and inflammation.

Accurate prediction of the prognoses of cancer patients and identification of prognostic biomarkers are both important for the improved treatment of cancer patients, in addition to enhanced anticancer drugs. Many previous bioinformatic studies have been carried out to achieve this goal; however, there remains room for improvement in terms of accuracy. In this study, we demonstrated that patient-specific cancer driver genes could be used to predict cancer prognoses more accurately. To identify patient-specific cancer driver genes, we first generated patient-specific gene networks before using modified PageRank to generate feature vectors that represented the impacts genes had on the patient-specific gene network. Subsequently, the feature vectors of the good and poor prognosis groups were used to train the deep feedforward network. For the 11 cancer types in the TCGA data, the proposed method showed a significantly better prediction performance than the existing state-of-the-art methods for three cancer types (BRCA, CESC and PAAD), better performance for five cancer types (COAD, ESCA, HNSC, KIRC and STAD), and a similar or slightly worse performance for the remaining three cancer types (BLCA, LIHC and LUAD). Furthermore, the case study for the identified breast cancer and cervical squamous cell carcinoma prognostic genes and their subnetworks included several pathways associated with the progression of breast cancer and cervical squamous cell carcinoma. These results suggested that heterogeneous cancer driver information may be associated with cancer prognosis.
