RESUMEN

BACKGROUND: Influenza vaccination is the key to prevent influenza-related disease, especially among high-risk populations. However, influenza vaccine uptake in China is low. This secondary analysis of a quasi-experimental trial aimed to understand factors associated with influenza vaccine uptake among children and older people stratified by funding context. METHODS: A total of 225 children (aged 0.5-8 years) and 225 older people (aged 60 years or above) were recruited from three clinics (rural, suburban and urban) in Guangdong Province. Participants were allocated into two groups based on funding contexts: a self-paid group (N = 150, 75 children and 75 older adults) in which participants paid full price for their vaccination; and a subsidized group (N = 300, 150 children and 150 older adults) in which varying levels of financial support was provided. Univariate and multivariable logistic regressions were conducted stratified by funding contexts. RESULTS: Overall, 75.0% (225/300) of participants in the subsidized group and 36.7% (55/150) in the self-paid group got vaccinated. Older adults had lower vaccination rates than children in both funding groups, while both age groups showed much higher uptake in the subsidized group than in the self-paid group (aOR = 5.96, 95% CI: 3.77-9.42, p = 0.001). In the self-paid group, having prior influenza vaccination history of children (aOR:2.61, 95%CI: 1.06-6.42) or older people (aOR:4.76, 95%CI: 1.08-20.90) was associated with increased influenza vaccine uptake compared to those who had no prior vaccination experiences in the family. While in the subsidized group, participants who got married or lived with partners (aOR = 0.32, 0.10-0.98) had lower vaccination uptake than single ones. Trust in providers' advice (aOR = 4.95, 95%CI:1.99, 12.43), perceived effectiveness of the vaccine (aOR: 12.18, 95%CI: 5.21-28.50), and experienced influenza-like illnesses in the family in the past year (aOR = 46.52, 4.10, 533.78) were associated with higher vaccine uptake. CONCLUSIONS: Older people had suboptimal vaccine uptake compared to children in both contexts and need more attention to enhance influenza vaccination. Tailoring interventions to different vaccine funding contexts may help improve influenza vaccination: In self-paid context, motivating people to accept their first ever influenza vaccination may be a promising strategy. In subsidized context, improving public confidence in vaccine effectiveness and providers' advice would be useful.

RESUMEN

BACKGROUND: Human papillomavirus (HPV) vaccination could prevent cervical and other HPV-associated cancers attributable to vaccine-associated HPV types. However, HPV vaccination coverage among women aged 9-18 years old is low in China. Common barriers include poor financial affordability, minimal public engagement, and low confidence in domestically produced HPV vaccines. Pay-it-forward offers an individual a free or subsidized service then an opportunity to voluntarily donate and/or create a postcard message to support future people. This study aims to assess the effectiveness of pay-it-forward as compared to standard-of-care self-paid vaccination to improve HPV vaccine uptake among adolescent girls aged 15-18 years, who are left out in the current pilot free HPV vaccination task force in some parts of China. METHODS: This is a two-arm randomized controlled trial in Chengdu, China. Eligible adolescent girls (via caregivers) will be randomly selected and recruited through four community health centers (one in the most developed urban areas, one in higher middle-income and one in lower middle-income suburban areas, and one in the least developed rural areas) using the resident registration list. A total of 320 participants will be randomized into two study arms (user-paid versus pay-it-forward vaccination) in a 1:1 ratio. The intervention assignment will be blinded to recruiters and participants using envelop concealment until the research assistants open the envelop to determine which treatment to deliver to each individual. The primary outcome of the study will be HPV vaccine uptake by administrative data. Secondary outcomes include costs, vaccine hesitancy, and the completion rates of the 3-dose HPV vaccination series. DISCUSSION: This study will investigate an innovative pay-it-forward strategy's effectiveness and economic costs to improve HPV vaccination among 15-18-year-old adolescent girls. Study findings will have implications for increasing HPV vaccine uptake in places where HPV vaccines are provided for a fee.

RESUMEN

Tomato powdery mildew, caused by Oidium neolycopersici, is a destructive fungal disease that damages almost all of the aerial parts of tomato, causing devastating losses in tomato production worldwide. WRKY transcription factors are key regulators of plant immunity, but the roles of ShWRKYs in wild tomato Solanum habrochaites LA1777 against O. neolycopersici still remain to be uncovered. Here, we show that ShWRKY81 is an important WRKY transcription factor from wild tomato Solanum habrochaites LA1777, contributing to plant resistance against O. neolycopersici. ShWRKY81 was isolated and identified to positively modulate tomato resistance against On-Lz. The transient overexpression of the ShWRKY81-GFP (green fluorescent protein) fusion protein in Nicotiana benthamiana cells revealed that ShWRKY81 was localized in the nucleus. ShWRKY81 responded differentially to abiotic and biotic stimuli, with ShWRKY81 mRNA accumulation in LA1777 seedlings upon On-Lz infection. The virus-induced gene silencing of ShWRKY81 led to host susceptibility to On-Lz in LA1777, and a loss of H2O2 formation and hypersensitive response (HR) induction. Furthermore, the transcripts of ShWRKY81 were induced by salicylic acid (SA), and ShWRKY81-silenced LA1777 seedlings displayed decreased levels of the defense hormone SA and SA-dependent PRs gene expression upon On-Lz infection. Together, these results demonstrate that ShWRKY81 acts as a positive player in tomato powdery mildew resistance.

RESUMEN

BACKGROUND: Lenvatinib is regarded as the first-line therapy for patients with unresectable hepatocellular carcinoma (HCC). This study assessed the efficacy and safety of lenvatinib with or without immune checkpoint inhibitors (ICIs) in patients with unresectable HCC. METHODS: In this multicentric retrospective study, patients with unresectable HCC who treated with lenvatinib with or without ICIs would be enrolled. Overall survival, progression-free survival, objective response rate, and disease control rate were calculated to assess the antitumor response. RESULTS: Between January 2019 and August 2020, 65 patients received lenvatinib plus ICIs while other 45 patients received lenvatinib. The baseline characteristics were comparable between the two groups. Lenvatinib plus ICIs provided significantly higher overall survival (hazard ratio = 0.47, 95% CI 0.26-0.85; p = 0.013) and progression-free survival (hazard ratio = 0.35, 95% CI 0.20-0.63; p < 0.001) than lenvatinib monotherapy. Moreover, patients with lenvatinib plus ICIs had significantly higher objective response rate (41.5% vs 20.0%, p = 0.023) and disease control rate (72.3% vs 46.7%, p = 0.009) per RECIST v1.1 than those with lenvatinib. No treatment-related deaths were observed. Grade 3 or greater adverse events occurring in 10% or more of patients in either treatment group were hypertension [13 (20.0%) of 65 patients treated with lenvatinib plus ICIs vs 8 (17.8%) of 45 patients treated with lenvatinib], and palmar-plantar erythrodysesthesia [seven (10.8%) vs two (4.4%)]. CONCLUSIONS: In this real-world study, lenvatinib combined with ICIs showed significantly promising efficacy and manageable safety than lenvatinib alone in patients with unresectable HCC.

RESUMEN

BACKGROUND & AIMS: The multiplicity of hepatocellular carcinoma (HCC) recurrence patterns is the most important determinant of patients' postsurgical survival. A systematic HCC recurrence classification is needed to help prevent and treat postoperative HCC recurrence in the era of precision medicine. METHODS: A total of 1319 patients with recurrent HCC from four hospitals were enrolled and divided into a development cohort (n = 916), internal validation cohort (n = 225) and external validation cohort (n = 178). A comprehensive study of patients' clinicopathological factors and biological features was conducted. RESULTS: Four subtypes of recurrence were identified, which integrated recurrence features, survival, effects on systemic and liver function and potential therapeutics after recurrence: type I (solitary-intrahepatic oligorecurrence); type II (multi-intrahepatic oligorecurrence); type III (progression recurrence) and type IV (hyper-progression recurrence). Type III~IV recurrence indicated exceptionally poor prognosis. Subsequently, two nomogram models were established for type III~IV recurrence prediction, and both demonstrated excellent predictive performance and applicability of pre and postoperative strategy formulation. Multiple biological analyses revealed that HCC cases with type III~IV recurrence were characterized by enrichment in p53 mutations, CCND1 amplification, high proliferation/metastasis potential, inactive metabolism and immune exhaustion features. Over-expression of high mobility group protein 2 (HMGA2) enhanced the highly malignant behaviour of HCC through multiple molecular pathways, making it a potential prognostic predictor and therapeutic target. CONCLUSIONS: This 'recurrent HCC classification' has important potential value in identifying patients with surgical benefit, predicting postsurgical survival and guiding treatment strategies. Multidimensional biological insights also increased knowledge of factors associated with HCC recurrence.

RESUMEN

Household surveys remain an essential method for estimating vaccine coverage in developing countries. However, the resulting estimates have inevitable and currently unmeasurable information biases due to inaccuracies in recall, low retention of home-based records (HBRs; i.e., vaccination cards), and inaccurate recording of vaccination on HBRs. We developed an innovative method with which to overcome these biases, enhance the validity of survey results, and estimate true vaccine coverage using nested serological assessments of immune markers. We enrolled children aged 12-23 months in vaccine coverage surveys in Karachi, Pakistan, from January to December 2016. Vaccination history was collected through verbal recall by the caregiver and, when available, by HBR. One-third of survey participants were randomly enrolled for serological testing for anti-measles virus immunoglobulin G antibody. We applied Bayesian latent class models to evaluate the misalignment among measles vaccination histories derived by recall, HBRs, and measles serology and estimated true measles vaccine coverage. The model-based estimate of true measles vaccine coverage was 61.1% (95% credible interval: 53.5, 69.4) among all survey participants. The standard estimate of 73.2% (95% confidence interval: 71.3, 75.1) defined by positive recall or HBR documentation substantially overestimated the vaccine coverage. Researchers can correct for information biases using serological assessments in a subsample of survey participants and latent class analytical approaches.

RESUMEN

Intelligent fault diagnosis methods based on deep learning becomes a research hotspot in the fault diagnosis field. Automatically and accurately identifying the incipient micro-fault of rotating machinery, especially for fault orientations and severity degree, is still a major challenge in the field of intelligent fault diagnosis. The traditional fault diagnosis methods rely on the manual feature extraction of engineers with prior knowledge. To effectively identify an incipient fault in rotating machinery, this paper proposes a novel method, namely improved the convolutional neural network-support vector machine (CNN-SVM) method. This method improves the traditional convolutional neural network (CNN) model structure by introducing the global average pooling technology and SVM. Firstly, the temporal and spatial multichannel raw data from multiple sensors is directly input into the improved CNN-Softmax model for the training of the CNN model. Secondly, the improved CNN are used for extracting representative features from the raw fault data. Finally, the extracted sparse representative feature vectors are input into SVM for fault classification. The proposed method is applied to the diagnosis multichannel vibration signal monitoring data of a rolling bearing. The results confirm that the proposed method is more effective than other existing intelligence diagnosis methods including SVM, K-nearest neighbor, back-propagation neural network, deep BP neural network, and traditional CNN.

RESUMEN

Antibodies targeting PD-1 have been demonstrated durable anti-cancer activity in certain cancer types. However, the anti-PD-1 antibodies are less or not efficacious in many situations, which might be attributed to co-expression of multiple inhibitory receptors or presence of immunosuppressive cells in the tumor microenvironment. Most of the anti-PD-1 antibodies used in clinical studies are of IgG4 isotype with the S228P mutation (IgG4S228P). The functional impact by the interaction of anti-PD-1 IgG4S228P antibody with Fc gamma receptors (FcγRs) is poorly understood. To assess the effects, we generated a pair of anti-PD-1 antibodies: BGB-A317/IgG4S228P and BGB-A317/IgG4-variant (abbreviated as BGB-A317), with the same variable regions but two different IgG4 Fc-hinge sequences. There was no significant difference between these two antibodies in binding to PD-1. However, BGB-A317/IgG4S228P binds to human FcγRI with high affinity and mediates crosslinking between PD-1 and FcγRI. In contrast, BGB-A317 does neither. Further cell-based assays showed that such crosslinking could reverse the function of an anti-PD-1 antibody from blocking to activating. More importantly, the crosslinking induces FcγRI+ macrophages to phagocytose PD-1+ T cells. In a mouse model transplanted with allogeneic human cancer cells and PBMCs, BGB-A317 showed significant tumor growth inhibition, whereas BGB-A317/IgG4S228P had no such inhibition. Immunohistochemistry study revealed an inverse correlation between FcγRI+ murine macrophage infiltration and the density of CD8+PD-1+ human T cells within tumors in the BGB-A317/IgG4S228P-treated group. These evidences suggested that FcγRI+ binding and crosslinking had negative impact on the anti-PD-1 antibody-mediated anti-cancer activity.

RESUMEN

BACKGROUND.: Chest radiographs (CXRs) are a valuable diagnostic tool in epidemiologic studies of pneumonia. The World Health Organization (WHO) methodology for the interpretation of pediatric CXRs has not been evaluated beyond its intended application as an endpoint measure for bacterial vaccine trials. METHODS.: The Pneumonia Etiology Research for Child Health (PERCH) study enrolled children aged 1-59 months hospitalized with WHO-defined severe and very severe pneumonia from 7 low- and middle-income countries. An interpretation process categorized each CXR into 1 of 5 conclusions: consolidation, other infiltrate, both consolidation and other infiltrate, normal, or uninterpretable. Two members of a 14-person reading panel, who had undertaken training and standardization in CXR interpretation, interpreted each CXR. Two members of an arbitration panel provided additional independent reviews of CXRs with discordant interpretations at the primary reading, blinded to previous reports. Further discordance was resolved with consensus discussion. RESULTS.: A total of 4172 CXRs were obtained from 4232 cases. Observed agreement for detecting consolidation (with or without other infiltrate) between primary readers was 78% (κ = 0.50) and between arbitrators was 84% (κ = 0.61); agreement for primary readers and arbitrators across 5 conclusion categories was 43.5% (κ = 0.25) and 48.5% (κ = 0.32), respectively. Disagreement was most frequent between conclusions of other infiltrate and normal for both the reading panel and the arbitration panel (32% and 30% of discordant CXRs, respectively). CONCLUSIONS.: Agreement was similar to that of previous evaluations using the WHO methodology for detecting consolidation, but poor for other infiltrates despite attempts at a rigorous standardization process.

RESUMEN

Official guidelines group together all cases of solitary hepatocellular carcinoma (HCC) without macroscopic vascular invasion, regardless of tumor size. Here, we examined whether this is justified based on overall survival (OS) after hepatic resection (HR). Patients with newly diagnosed solitary HCC treated by initial HR from January 2004 to October 2013 were classified into six groups based on tumor size (in 2-cm increments). Combining adjacent categories with similar OS led to three groups: ≤5 cm (n = 426), >5 and ≤8 cm (n = 229), and >8 cm (n = 202). Among all patients, median survival time was 62 months, and OS was 95 % at 1 year, 73 % at 3 years, and 54 % at 5 years. Patients in the ≤5 cm group showed significantly higher OS (P < 0.001) and lower tumor recurrence (P = 0.004) than those in the >5 and ≤8 cm group, who in turn showed significantly higher OS (P = 0.003) and lower tumor recurrence (P = 0.021) than those in the >8 cm group. Our results suggest that patients with solitary HCC should be subclassified based on tumor size for more accurate prognosis. We propose defining solitary HCC tumors >5 and ≤8 cm as "large" and tumors >8 cm as "huge".

RESUMEN

AIM: The suitability of hepatic resection for older patients remains controversial. This study aimed to investigate whether age influences overall survival of patients with hepatocellular carcinoma (HCC) after resection. METHODS: Records of 1,132 patients with HCC after hepatic resection were retrospectively reviewed. Overall survival (OS) was compared between younger and older patients based on five cut-off ages (30, 40, 50, 60, and 70 years). RESULTS: Across all patients, OS was 89.7% at 1 year, 67.7% at 3 years, and 47.7% at 5 years. OS was similar between younger and older patients at all cut-off ages (all P > 0.1), but OS was marginally lower among patients >70 years old than those ≤70 (P = 0.090). Multivariate analyses identified several risk factors for lower OS: preoperative serum albumin <35 g/L, alanine aminotransferase >80 U/L, α-fetoprotein ≥400 ng/ml, presence of esophagogastric varices or macrovascular invasion, incomplete/absent tumor capsule, tumor size >10 cm, tumor number ≥3, and major hepatectomy. CONCLUSION: Age does not influence the prognosis of patients with HCC after hepatic resection. Older patients should be considered for curative resection if remnant liver volume and liver function are adequate. J. Surg. Oncol. 2016;114:966-970. © 2016 Wiley Periodicals, Inc.

RESUMEN

AIM: Conventional transarterial chemoembolization (cTACE) is widely used for treating patients with inoperable hepatocellular carcinoma (HCC). A variation on the technique based on drug-eluting beads (DEB-TACE) has recently entered the clinic, but trials of its safety and efficacy have given conflicting results. This systematic review aimed to gain a current, comprehensive picture of how DEB-TACE compares with cTACE. METHODS: MEDLINE, EMBASE, the Cochrane Library, the Chinese National Knowledge Infrastructure database and clinical trial registries were searched through June 2014. Risk ratios (RR), hazard ratios (HR) and 95% confidence intervals (CI) were calculated. RESULTS: The analysis included four randomized controlled trials, one uncontrolled prospective study and one prospective case-control study, altogether involving 652 patients. Overall survival benefit was similar between cTACE and DEB-TACE patients (HR = 1.07, 95% CI = 0.82-1.40, P = 0.875). However, DEB-TACE was associated with a significantly higher objective tumor response rate (RR = 1.14, 95% CI = 1.01-1.29, P = 0.03) and a slightly lower incidence of adverse events. CONCLUSION: Though the available evidence suggests that although DEB-TACE is associated with better tumor response and potentially fewer adverse events, it does not provide greater survival benefit than cTACE. These results need to be validated in high-quality trials with large sample size.

RESUMEN

OBJECTIVE: The efficacy and safety of hepatic resection (HR) to treat patients with Barcelona Clinic Liver Cancer (BCLC) stage B and C hepatocellular carcinoma (HCC) was retrospectively assessed. BACKGROUND: Although guidelines from the European Association for the Study of Liver Disease and the American Association for the Study of Liver Disease do not recommend HR for treating BCLC stage B/C HCC, several Asian and European studies have come to the opposite conclusions. METHODS: A consecutive sample of 1259 patients with BCLC stage B/C HCC who underwent HR (n = 908) or transarterial chemoembolization (TACE, n = 351) were included. Moreover, propensity score-matched patients were analyzed to adjust for any baseline differences. In parallel with this retrospective clinical study, the MEDLINE database was searched for studies evaluating the efficacy and safety of HR for BCLC stage B/C HCC. RESULTS: Among our patient sample, the 90-day mortality rate in the HR group was 3.1%. HR provided a survival benefit over TACE at 1, 3, and 5 years (88% vs 81%, 62% vs 33%, and 39% vs 16%, respectively; all P < 0.001). Propensity scoring and subgroup analyses based on tumor size, tumor number, presence or absence of macrovascular invasion, and portal hypertension (PHT) also showed that HR was associated with better long-term survival than TACE. All 36 studies identified in our literature search reported that HR is associated with good long-term survival and low morbidity. Multivariate analyses revealed that alpha-fetoprotein more than or equal to 400 ng/mL, diabetes mellitus, macrovascular invasion, and PHT are independent predictors of poor prognosis in patients with BCLC stage B/C HCC. CONCLUSIONS: Our clinical and literature analyses suggest that in patients with HCC with preserved liver function, the presence of large, solitary tumors, multinodular tumors, macrovascular invasion, or PHT are not contraindications for HR.

RESUMEN

Breast cancer may be caused by several factors, including polymorphisms in the microsomal epoxide hydrolase (mEH) gene. Previous work suggested an association between mEH polymorphism and risk of breast cancer, but the results have been inconsistent. PubMed, EMBASE, Google Scholar, and the Chinese National Knowledge Infrastructure database were systematically searched to identify relevant studies. A meta-analysis was performed to examine the association between Tyr113His and His139Arg mEH polymorphisms and susceptibility to breast cancer. Odds ratios (ORs) with 95 % confidence intervals (CIs) were calculated to assess the strength of the association. Seven studies involving 6,357 cases and 8,089 controls were included in this study. The Tyr113His mEH polymorphism did not affect breast cancer risk in the allelic contrast model (OR = 0.99, 95 % CI = 0.94-1.04, P = 0.58), the dominant genetic model (OR = 1.14, 95 % CI = 0.88-1.48, P = 0.33), or the recessive genetic model (OR = 1.03, 95 % CI = 0.96-1.10, P = 0.43). Similarly, the His139Arg mEH polymorphism was not associated with breast cancer risk in the allelic contrast model (OR = 0.97, 95 % CI = 0.91-1.04, P = 0.44), the dominant genetic model (OR = 1.01, 95 % CI = 0.84-1.21, P = 0.94), or the recessive genetic model (OR = 1.04, 95 % CI = 0.96-1.12, P = 0.35). The mEH polymorphisms Tyr113His and His139Arg are not risk factors for breast cancer. Further, large and well-designed studies are required to confirm this conclusion.

This research synthesis examined HIV/AIDS surveillance and health care financing data and reviewed relevant research literature to describe HIV epidemiology, outcomes, funding, and contributing factors to the HIV epidemic in the Southern USA with particular focus on a group of Southern states with similar demographic and disease characteristics and comparable HIV epidemics (Alabama, Georgia, Florida, Los Angeles, Mississippi, North Carolina, South Carolina, Tennessee, and Texas). These states are hereafter referred to as "targeted Southern states." Eight of the 10 states with the highest HIV diagnosis rates in 2011 were in the Southern USA; six were targeted states. Forty-nine percent of HIV diagnoses were in the South in 2011, which contains only 37% of the US population. The targeted states region had the highest HIV diagnosis rate than any other US region in 2011. The South was also found to have the highest HIV-related mortality and morbidity rates in the USA. The high levels of poverty, HIV-related stigma, and STDs found in the South, particularly in the targeted Southern states, likely contribute to greater HIV incidence and mortality. The disproportionate impact of HIV in the South, particularly among targeted states, demonstrates a critical need to improve HIV prevention and care and address factors that contribute to HIV disease in this region.

RESUMEN

This study was designed to test the feasibility and child clinical outcomes for group-based trauma-focused cognitive behavior therapy (TF-CBT) for orphaned children in Tanzania. There were 64 children with at least mild symptoms of grief and/or traumatic stress and their guardians who participated in this open trial. The TF-CBT for Child Traumatic Grief protocol was adapted for use with a group, resulting in 12 weekly sessions for children and guardians separately with conjoint activities and 3 individual visits with child and guardian. Using a task-sharing approach, the intervention was delivered by lay counselors with no prior mental health experience. Primary child outcomes assessed were symptoms of grief and posttraumatic stress (PTS); secondary outcomes included symptoms of depression and overall behavioral adjustment. All assessments were conducted pretreatment, posttreatment, and 3 and 12 months after the end of treatment. Results showed improved scores on all outcomes posttreatment, sustained at 3 and 12 months. Effect sizes (Cohen's d) for baseline to posttreatment were 1.36 for child reported grief symptoms, 1.87 for child-reported PTS, and 1.15 for guardian report of child PTS.

RESUMEN

Aims: Rabson-Mendenhall syndrome (RMS) is a rare autosomal, recessive disorder characterized by severe insulin resistance due to mutations in the insulin receptor (INSR) gene. This study aims to analyze the clinical features and gene mutations in RMS, which have not been extensively studied. Methods: PubMed, Embase, the China National Knowledge Infrastructure, and Wanfang were searched for "Rabson-Mendenhall syndrome" or "Black acanthosis hirsutism insulin resistance syndrome." Results: A total of 42 cases from 33 articles were included. The body mass index ranged from 18.50 to 20.00 kg/m2 with an average of 16.00 kg/m2. There were no overweight (25.00∼29.90 kg/m2) or obese (≥30.00 kg/m2) patients. Acanthosis was present in 29 cases (29/42, 69.05%); growth retardation in 25 cases (25/42, 59.52%); dental anomalies including absence of teeth, crowding, and malocclusion in 23 cases (23/42, 54.76%); and hirsutism in 17 cases (17/42, 40.48%). The average glycosylated hemoglobin was 9.35%, and the average fasting blood-glucose was 8.44 mmol/L; the mean fasting insulin was 349.96 µIU/mL, and the average fasting C-peptide was 6.00 ng/mL. Diabetes was reported in 25 cases (25/33, 75.76%) all of which were diagnosed before 23 years old. All 42 patients had recorded gene mutations, with 22 patients (22/42, 52.38%) having ≥ 2 mutations and 20 cases (20/42, 47.62%) having only 1 mutation. No statistical differences were found in clinical features and laboratory parameters between patients with different mutations. Conclusion: The study indicates that RMS should be considered in young patients with hyperinsulinemia, hyperglycemia with low weight, acanthosis nigricans, growth retardation, dental anomalies, and hirsutism.

RESUMEN

INTRODUCTION: A Chinese clinical trial has demonstrated that a prosocial pay-it-forward intervention that offered subsidized vaccination and postcard messages effectively increased influenza vaccine uptake and vaccine confidence. This secondary analysis explored the potential mediating role of vaccine confidence on the association between a pay-it-forward intervention and influenza vaccine uptake, and how this might vary by individual annual income levels. METHODS: Data from 300 participants (150 standard-of-care and 150 pay-it-forward participants) were included in the analysis. We conducted descriptive analysis of demographic and vaccine confidence variables. Multivariable regression and mediation analysis on interventions, vaccine confidence and vaccine uptake were conducted. A sub-group analysis was conducted to further understand whether associations between these variables vary by income levels (<=$1860 or >$1860). RESULTS: The pay-it-forward intervention was significantly associated with greater levels of perceived influenza vaccine importance (adjusted odds ratio (aOR) = 3.60, 95 %CI: 1.77-7.32), effectiveness (aOR = 3.37, 95 %CI: 1.75-6.52) and safety (aOR = 2.20, 95 %CI: 1.17-4.15). Greater perceived influenza vaccine importance was associated with increased vaccine uptake (aOR = 8.51, 95 %CI: 3.04-23.86). The indirect effect of the pay-it-forward intervention on vaccination was significant through improved perceived influenza vaccine importance (indirect effect1 = 0.07, 95 %CI: 0.02-0.11). This study further revealed that, irrespective of the individual income level, the pay-it-forward intervention was associated with increased vaccine uptake when compared to the standard-of-care approach. CONCLUSIONS: Pay-it-forward intervention may be a promising strategy to improve influenza vaccine uptake. Perceived confidence in vaccine importance appears to be a potential mediator of the association between pay-it-forward and vaccine uptake.

RESUMEN

BACKGROUND: Despite the increasing focus on strengthening One Health capacity building on global level, challenges remain in devising and implementing real-world interventions particularly in the Asia-Pacific region. Recognizing these gaps, the One Health Action Commission (OHAC) was established as an academic community for One Health action with an emphasis on research agenda setting to identify actions for highest impact. MAIN TEXT: This viewpoint describes the agenda of, and motivation for, the recently formed OHAC. Recognizing the urgent need for evidence to support the formulation of necessary action plans, OHAC advocates the adoption of both bottom-up and top-down approaches to identify the current gaps in combating zoonoses, antimicrobial resistance, addressing food safety, and to enhance capacity building for context-sensitive One Health implementation. CONCLUSIONS: By promoting broader engagement and connection of multidisciplinary stakeholders, OHAC envisions a collaborative global platform for the generation of innovative One Health knowledge, distilled practical experience and actionable policy advice, guided by strong ethical principles of One Health.

RESUMEN

BACKGROUND: Hepatocellular carcinoma (HCC) patients with clinically significant portal hypertension (CSPH) and beyond the Milan criteria undergoing hepatectomy were previously considered to be at high risk and to have a poor prognosis, especially for major hepatectomy. The aim of this study was to investigate the safety and efficacy of hepatectomy in those patients. METHODS: Data were collected on HCC patients with CSPH treated at a single centre from January 2010 to October 2021. Propensity score-matched (PSM) analysis was used to balance the bias between groups. RESULTS: Of the included patients, 556 underwent hepatectomy and 172 underwent transcatheter arterial chemoembolization (TACE). Comparison of patients beyond the Milan criteria and those with Milan criteria underwent hepatectomy, the 90-day mortality and complication rates were similar in the two groups. However, the overall survival (OS) and recurrence-free survival (RFS) of patients within the Milan criteria were significantly better than those beyond the Milan criteria (p < 0.001). In HCC patients beyond the Milan criteria, OS of performing hepatectomy was significantly longer than TACE (p < 0.001). Within HCC patients beyond the Milan criteria underwent hepatectomy, there was no significant difference in 90-day mortality and complications between minor and major hepatectomy in patients beyond the Milan criteria and no significant difference in RFS and OS after PSM. CONCLUSIONS: Hepatectomy for HCC patients with CSPH and beyond the Milan criteria is safe and feasible, with an acceptable prognosis and no significant difference between minor and major hepatectomy.
