BackgroundSARS-CoV-2, the causative virus of the COVID-19 global pandemic, leads to a wide variety of responses among patients. Some of them present a very severe phenotype, while others only experience mild symptoms or are even asymptomatic. This differential prognosis is tightly related to the inflammatory status of the patient. Although WHO declared the end of the emergency, the pandemic caused a great socio-sanitary impact in all countries. Thus, the possible outbreak of new biological diseases in the future makes it necessary to deepen the knowledge of this uncontrolled immune response and look for reliable biomarkers to help us predict its potential health impact. Specialized pro-resolving lipid mediators (SPMs) as lipoxins are endogenous mediators synthesized from arachidonic acid in the resolution stage of any inflammatory process. These lipids have pro-resolving actions in several pathological models, including reducing NF-κB-mediated inflammation, and inducing the antioxidant response through the Nrf-2 pathway. Thus, although a potential relationship has already been suggested between low levels of SPMs and COVID-19 severity, their true role as a predictive biomarker is still unknown.Methods and resultsIn this study, we have analyzed by ELISA the serum levels of lipoxin A4 (LXA4) in a representative Spanish cohort. We found reduced levels in deceased patients when compared to mild or severe patients, concomitant with a decrease in the LXA4 biosynthetic pathway and an increase in its degradation pathway. Furthermore, we have studied the correlation between the levels of this SPM and several pathology indicators, finding a significant correlation between increased LXA4 levels and a better prognosis of the patients.ConclusionWe propose to measure systemic LXA4 as a new promising biomarker to predict the survival in patients affected by SARS-CoV-2 and presumably to other viruses that can affect humanity in the future.

BackgroundAsthma exacerbation significantly contribute to disease mortality and result in heightened health care expenditures. This study was aimed at gaining important new insights into the heterogeneity of epithelial and immune cells and elucidating key regulatory genes involved in the pathogenesis of asthma exacerbation.MethodsFunctional enrichment, pseudotime, metabolism and cell-cell communication analyses of epithelial cells and immune cells in single-cell RNA sequencing (scRNA-seq) dataset were applied. Immune infiltration analysis was performed in bulk RNA sequencing (bulk RNA-seq) dataset. Key regulatory genes were obtained by taking the intersection of the differentially expressed genes (DEGs) between control and asthma group in epithelial cells, immune cells and bulk RNA-seq data. Asthma animal and in vitro cell line models were established to verify the key regulatory genes expression by employing quantitative reverse transcription polymerase chain reaction (qRT-PCR).ResultsScRNA-seq analysis identified 7 epithelial subpopulations and 14 distinct immune cell types based on gene expression profiles. Further analysis demonstrated that these cells manifested high heterogeneity at the levels of functional variations, dynamics, communication patterns and metabolic changes. Notably, TMPRSS11A, TUBA1A, SCEL, ICAM4, TMPRSS11B, IGFBP2, CLC, NFAM1 and F13A1 were identified as key regulatory genes of asthma. The results of the qRT-PCR demonstrated that the 9 key regulatory genes were involved in asthma.ConclusionsWe systematically explored epithelial and immune characteristics in asthma exacerbation and identified 9 key regulatory genes underlying asthma occurrence and progression, which may be valuable for providing new insights into the cellular and molecular mechanisms driving asthma exacerbations.

BackgroundMedical simulations have emerged as a valuable tool in anatomical-medical training, allowing healthcare professionals to gain hands-on experience in a controlled and safe environment. One such simulation platform is SimLife®, which uses the Pulse for Practice (P4P) system to enable realistic restoration of airflow (“re-ventilation”) and blood flow (“revascularization”) in bodies donated to science.ObjectiveThis study aimed to evaluate the feasibility of introducing SimLife® technology in Italy. Additionally, it assessed the impact of this technology across various medical specialties, utilizing a minimal number of donated bodies.MethodsThe study utilized the existing body donation program and dissection rooms at the Anatomy Center of the University of Bologna. 62 participants from 13 medical specialties performed simulations using the SimLife® P4P platform. Post-simulation, structured interviews were used to collect data on the interventions performed, participant perceptions of the technology’s usefulness, enjoyment, and willingness to repeat the experience, as well as critical issues encountered.ResultsKey findings include that 86% of participants rated SimLife® technology as extremely useful for post-lauream training, while 84% found it highly beneficial for team-building activities. A total of 31 interventions were successfully performed across various anatomical regions, with participants reporting high satisfaction and a strong willingness to repeat the simulation experience.ConclusionThe findings support the effectiveness of SimLife® technology for body donor re-ventilation and revascularization, reinforcing its value for medical training across various specialties.

Published: January 2025

ObjectiveThis study aims to discuss the dose-response relationship between the Life's Essential 8 (LE8) score and chronic obstructive pulmonary disease (COPD).MethodsWe screened data from the National Health and Nutrition Examination Survey (NHANES) database for the years 2007–2018. Logistics regression analysis and subgroup analysis were used to explore the relationship between cardiovascular health (CVH) and COPD based on the LE8 score. Additionally, restricted cubic spline (RCS) plots were drawn to visually display the dose-response relationship.ResultsA total of 12,517 participants were included, of which 835 had COPD. After multivariable adjustment, the LE8 score was found to be linearly and inversely associated with the risk of developing COPD. A similar relationship was observed in the scores for health behavior factors, whereas the relationship was weaker for health factors. The RCS plots visually demonstrated the aforementioned dose-response relationship. Moreover, subgroup analyses showed that this relationship remained robust across different groups.ConclusionLE8 scores are inversely and linearly associated with the risk of developing COPD. Higher LE8 scores can reduce the risk of developing COPD in individuals over 40 years old, especially concerning health behavior factors.

Published: January 2025

IntroductionPlants detect the invasion of microbial pathogens through pathogen-associated molecular patterns (PAMPs). Cold shock proteins (CSPs) are a class of PAMPs specifically recognized by Solanales plants. While peptide inoculation studies have revealed the effects of CSPs, their in vivo roles remain poorly understood.MethodsA model system involving the interactions between Pseudomonas fluorescens and P. syringae pv. tomato DC3000 with Nicotiana benthamiana has been widely used to investigate the molecular mechanism of plant-microbe interactions. Here, we employed this model system to explore the in vivo roles of CSPs in modulating plant immunity by multiple genetic approaches.ResultsOur findings revealed that three highly-conserved CSPs were identified in Pseudomonas strains. Transient expression of these CSPs neither induced reactive oxygen species (ROS) production nor suppressed the hypersensitive response (HR) in N. benthamiana, however, it restricted bacterial effector translocation. Genetic analysis revealed that these CSPs did not contribute to the ROS burst or HR inhibition in vivo but were functionally redundant in suppressing effector translocation in a flagellin (FliC)-independent manner. Furthermore, we demonstrated that the suppression of effector translocation mediated by CSPs was less pronounced compared to that triggered by FliC. Additionally, inoculation with csp15 and csp22 epitopes triggered the pattern-triggered immunity-associated suppression of effector translocations.DiscussionThis study revealed the redundant roles of CSPs in suppressing bacterial effector translocation in vivo, providing deep insights into the PTI elicited by cytoplasmic bacterial proteins.

Published: January 2025

BackgroundGlomerular diseases significantly impact global health. This study investigated public interest in five common glomerular diseases.MethodsGoogle Trends™ were used to analyze search activity from January 2004 to December 2024 for IgA nephropathy (IgAN), membranous glomerulonephritis (MN), focal segmental glomerulosclerosis (FSGS), lupus nephritis (LN), and diabetic nephropathy (DN). Data were retrieved both globally and in English-speaking countries, including the United States. Monthly and yearly relative search activity were assessed and compared.ResultsGlobally, IgAN had the highest average relative search activity, followed by DN, FSGS, LN, and MN. Both IgAN and FSGS exhibited declining trends, while LN showed an upward pattern. MN and DN experienced a modest decline before 2016, preceded by a slight increase. Among English-speaking countries, search interest was predominantly concentrated in five countries, primarily including the United States, United Kingdom, Canada, and Australia, with the United States consistently ranking as the leading country. For IgAN, LN, and MN, the trends observed in the United States appeared to align with global data. In contrast, search interest for FSGS exceeded global levels, while interest in DN was slightly lower than global activity. In the United States, IgAN, FSGS, and LN were most prominent in North Dakota, Massachusetts, and Delaware, respectively, while DN and MN saw peak activity in West Virginia.ConclusionPublic engagement with glomerular diseases has not uniformly grown, at least in English-speaking countries, emphasizing the need for enhanced awareness efforts. Future analysis should prioritize search terms in the predominant language of each country.

Published: January 2025

ObjectiveThe cause of late-onset first epileptic seizures (LOFES) in older age is often not readily evident. In absence of probable causes, it has been suggested that cerebral small vessel disease (CSVD), which is common with increasing age, may be crucial. We aimed to further investigate the impact of white matter lesion (WML) burden and distribution pattern on LOFES.MethodsWe retrospectively compared structural MRI of LOFES patients (n = 39) aged 60 years or older to controls with a transient ischemic attack (TIA, n = 38) and to patient controls (n = 35). WML segmentation was performed on FLAIR images using the SPM based automated lesion prediction algorithm of the LST toolbox and careful manual adjustment. Further, a dichotomization of WML was achieved by use of the BIANCA masking function. A voxel-based morphometry (VBM) analysis was additionally performed on T1 weighted sequences using the automated SPM12 based CAT12 software.ResultsComparing intrapersonal volume ratios adjusted for the effects of gender and age, we found that the WML distribution was shifted to the juxtacortical compartment in LOFES patients. Among several influencing variables a path analysis could additionally show that this juxtacortical weighting of WML was a significant predictor for LOFES (β = 0.509, p &lt; 0.001). With regard to total WML volume, LOFES and TIA patients did not differ significantly. Compared to TIA group, LOFES patients gray matter volume was regionally decreased in the right pre- and postcentral gyrus.SignificanceBy using algorithm-based automated lesion segmentation software tools and VBM analysis we could highlight that a juxtacortical weighting of WML distribution and regionally decreased gray matter volume distinguished LOFES from TIA and PC groups in our sample.

BackgroundBeta-hydroxy-beta-methylbutyrate (HMB) is beneficial for restoring muscle mass. However, the evidence supporting its use in critically ill patients remains unclear. We conducted a systematic review and meta-analysis of HMB in this population to ascertain its effects.MethodsWe searched PubMed, Embase, China National Knowledge Infrastructure, Wanfang, and the Cochrane database for articles focusing on adult patients receiving HMB compared to controls. The primary outcome was mortality. To explore potential heterogeneity, we assessed study quality and performed subgroup analysis, sensitivity analysis, and quality of evidence.ResultsNine randomized controlled trials were included. There were some differences in the study design, HMB protocols, and muscle measurements among these trials. Overall, there were no significant differences in mortality between the HMB and the control groups (risk ratio = 0.96; 95% CI, 0.44–2.08; P = 0.92). This finding was confirmed by the subgroup and sensitivity analyzes. Patients in the HMB group had similar durations of MV [mean difference (MD), –0.40; 95% CI, –0.91 to 0.12; P = 0.13], ICU stay (MD, –0.61 days; 95% CI, –3.59 to 2.38; P = 0.69), and hospital stay (MD, 1.52 days; 95% CI, –1.18 to 4.22; P = 0.27). In addition, HMB did not affect changes in body weight (P = 0.53), body mass index (P = 0.56), or quadriceps thickness (P = 0.74). The outcomes of changes in skeletal muscle area (P = 0.95) and muscle loss (P = 0.16) were similar between the two groups.ConclusionBeta-hydroxy-beta-methylbutyrate (HMB) did not improve the mortality or other clinical outcomes in critically ill patients. This may be because of the different HMB strategies used in the included trials. Our findings provide insights into future research designs that explore the clinical efficacy of HMB in this patient population.

Published: January 2025

BackgroundNonalcoholic fatty liver disease (NAFLD) has emerged as a significant global health concern, with advanced fibrosis increasing mortality risks. Despite the abundance of dietary guidelines for managing NAFLD, the precise impact of diet quality on mortality among individuals with advanced fibrosis remains elusive. This study aims to explore the influence of five dietary quality indexes on mortality among NAFLD patients and advanced fibrosis patients.MethodsThis study utilized data from the National Health and Nutrition Examination Survey (NHANES) spanning from 2005 to 2018 to assess dietary quality based on the Alternate Mediterranean Diet (aMED), Healthy Eating Index-2020 (HEI-2020), Dietary Approach to Stop Hypertension (DASH), Alternate Healthy Eating Index (AHEI), and Dietary Inflammatory Index (DII). Weighted Cox proportional hazard regression models along with restricted cubic splines and subgroup analyses were employed in this study.ResultsThe analysis encompassed 3,634 NAFLD patients. After a median follow-up of 89 months, it was found that higher scores on the aMED (HR 0.814, 95% CI 0.681–0.972), HEI-2020 (HR 0.984, 95% CI 0.972–0.997), DASH (HR 0.930, 95% CI 0.883–0.979), and AHEI (HR 0.980, 95% CI 0.966–0.995) were associated with lower mortality risks, while DII scores (HR 1.280, 95% CI 1.098–1.493) indicated an increased risk of mortality. Additionally, a nonlinear relationship was identified solely between AHEI scores and all-cause mortality in NAFLD patients. Notably, among patients with advanced fibrosis, HEI-2020 as a categorical variable (T3: HR 0.519, 95% CI 0.280–0.964), DASH as a continuous variable (continuous: HR 0.921, 95% CI 0.849–0.999), AHEI (continuous: HR 0.971, 95% CI 0.945–0.997; T2: HR 0.545, 95% CI 0.310–0.960; T3: HR 0.444, 95% CI 0.245–0.804), and DII (continuous: HR 1.311, 95% CI 1.121–1.534; T3: HR 2.772, 95% CI 1.477–5.202) exhibited significant associations with all-cause mortality. Subgroup analyses revealed an interaction between AHEI scores and sex among NAFLD patients, where higher AHEI scores correlated with lower all-cause mortality in females, but no such association was observed in males. For other dietary quality, subgroup analyses indicated that their relationships with mortality were robust.ConclusionOur study suggests that a high-quality diet could potentially mitigate mortality risk in both NAFLD and advanced fibrosis patients.

IntroductionHuman papillomavirus (HPV) vaccination and intentions, their correlates, and barriers among age-eligible parents and their children living in very economically disadvantaged communities were assessed.MethodsParents (N=198; 45% Black, 42% Latine, 57% educated &lt;=high school [HS], 74% income &lt;$60k annually) with children ages 10-17 from Washington, DC and Hackensack, NJ were intercepted at community events and surveyed.ResultsAmong age-eligible parents, 20% were vaccinated against HPV. Comparing vaccinated to unvaccinated parents, those who were non-white (OR=5.5, 95% CI=3.5, 9.4, p&lt;0.001) and with unvaccinated children (OR=8.9, 95% CI=3.7, 23.3, p&lt;0.001) were less likely to be vaccinated themselves. Among children, 37% were vaccinated. Unvaccinated children were more likely to have parents who were non-white (OR=2.7, 95% CI=2.6, 2.8, p&lt;.01), with a &lt;=HS education (OR=3.0, 95% CI=1.52, 6.25, p&lt;.01), and were unvaccinated themselves (OR=10.2, 95% CI=4.01, 28.61, p&lt;.001). Nearly two-thirds (63%) of parents with unvaccinated children expressed an intention to vaccinate within the next year: 48% confirmed receiving advice from a healthcare provider to do so. Common HPV vaccine barriers included lack of information (35%), safety concerns (16%), and perceptions of sexual inactivity (13%). An adjusted model revealed an interaction between parent education and medical mistrust (B=.35, SE=.13, 95% CI=0.09, 0.61, p&lt;.01). For parents with &lt;=HS education, when levels of provider trust were strong, they were more open to vaccinating their children.ConclusionsHPV vaccine prevalence was low among parents and children living in disadvantaged communities. Comprehensive education and intervention to build trust are warranted to prevent the spread of HPV-linked cancers and reduce cancer disparities.
A comparative analysis and survival analysis of open versus minimally invasive radical antegrade modular pancreatosplenectomy for pancreatic cancer: a systematic review and meta-analysis
Authors: Zhou Yating , Xue Fei 
Published: January 2025

BackgroundPancreatic ductal adenocarcinoma (PDAC) is a major public health concern, ranking as the fourth leading cause of cancer-related mortality in the United States. Traditional surgical approaches often yield suboptimal outcomes, highlighting the need for innovative surgical strategies. Radical antegrade modular pancreatosplenectomy (RAMPS) has demonstrated improvements in surgical visualization and oncological outcomes. Recently, laparoscopic RAMPS (L-RAMPS) has been introduced as a minimally invasive alternative.ObjectivesThis meta-analysis aims to compare the safety and efficacy of open RAMPS (O-RAMPS) versus L-RAMPS, focusing on operative outcomes, minimally invasive outcomes, intra-abdominal outcomes, overall postoperative outcomes, and oncologic outcomes.MethodsA systematic review and meta-analysis were conducted following PRISMA guidelines. Eligible studies included prospective or retrospective cohort studies and randomized controlled trials comparing L-RAMPS with O-RAMPS. Data were extracted from EMBASE, PubMed, and the Cochrane Library databases through September 16, 2023. The ROBINS-I tool was used to assess the risk of bias. Statistical analyses included odds ratios (OR), risk differences (RD), mean differences (MD), and survival analyses.ResultsEight studies involving 588 patients were included. O-RAMPS was associated with longer operative times (MD = 39.39 minutes, 95% CI = 22.93 to 55.84) and greater blood loss (MD = -231.84 mL, 95% CI = -312.00 to -151.69). No significant differences were observed in blood transfusion rates, pancreatic fistula rates, delayed gastric emptying, or length of hospital stay. L-RAMPS demonstrated a shorter time to oral feeding (MD = -0.79 days, 95% CI = -1.35 to -0.22). Survival analysis suggested a potentially improved long-term prognosis for L-RAMPS.ConclusionL-RAMPS offers advantages over O-RAMPS in terms of reduced blood loss, faster time to oral feeding, and potentially better long-term prognosis. Further research is warranted, particularly regarding the learning curve of L-RAMPS and its broader applicability.Systematic review registrationhttps://www.crd.york.ac.uk/prospero, identifier CRD42024498383.
