Ruiz-Botella M, Manrique S, Gomez J, Bodí M. Advancing ICU patient care with a Real-Time predictive model for mechanical Power to mitigate VILI. Int J Med Inform 2024; 189:105511. [PMID: 38851133 DOI: 10.1016/j.ijmedinf.2024.105511] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2024] [Revised: 05/24/2024] [Accepted: 05/29/2024] [Indexed: 06/10/2024]
Abstract
BACKGROUND Invasive Mechanical Ventilation (IMV) in Intensive Care Units (ICU) significantly increases the risk of Ventilator-Induced Lung Injury (VILI), necessitating careful management of mechanical power (MP). This study aims to develop a real-time predictive model of MP utilizing Artificial Intelligence to mitigate VILI. METHODOLOGY A retrospective observational study was conducted, extracting patient data from Clinical Information Systems from 2018 to 2022. Patients over 18 years old with more than 6 h of IMV were selected. Continuous data on IMV variables, laboratory data, monitoring, procedures, demographic data, type of admission, reason for admission, and APACHE II at admission were extracted. The variables with the highest correlation to MP were used for prediction and IMV data was grouped in 15-minute intervals using the mean. A mixed neural network model was developed to forecast MP 15 min in advance, using IMV data from 6 h before the prediction and current patient status. The model's ability to predict future MP was analyzed and compared to a baseline model predicting the future value of MP as equal to the current value. RESULTS The cohort consisted of 1967 patients after applying inclusion criteria, with a median age of 63 years and 66.9 % male. The deep learning model achieved a mean squared error of 2.79 in the test set, indicating a 20 % improvement over the baseline model. It demonstrated high accuracy (94 %) in predicting whether MP would exceed a critical threshold of 18 J/min, which correlates with increased mortality. The integration of this model into a web platform allows clinicians real-time access to MP predictions, facilitating timely adjustments to ventilation settings. CONCLUSIONS The study successfully developed and integrated in clinical practice a predictive model for MP. This model will assist clinicians allowing for the adjustment of ventilatory parameters before lung damage occurs.

Abstract
The electromagnetic form factors of the proton and neutron encode information on the spatial structure of their charge and magnetization distributions. While measurements of the proton are relatively straightforward, the lack of a free neutron target makes measurements of the neutron's electromagnetic structure more challenging and more sensitive to experimental or model-dependent uncertainties. Various experiments have attempted to extract the neutron form factors from scattering from the neutron in deuterium, with different techniques providing different, and sometimes large, systematic uncertainties. We present results from a novel measurement of the neutron magnetic form factor using quasielastic scattering from the mirror nuclei ^{3}H and ^{3}He, where the nuclear effects are larger than for deuterium but expected to largely cancel in the cross-section ratios. We extracted values of the neutron magnetic form factor for low-to-modest momentum transfer, 0.6

Abstract
Suicide by firearm remains one of the leading causes of violence-related injury death in the United States each year. The mortality rate from these injuries is high, resulting in a paucity of outcome data in the literature regarding injuries to the maxillofacial region. This has largely been attributed to a lack of funding for research in this area compared to other leading causes of mortality in the United States. The aim of this study was to detail the authors' experience and approach to complex maxillofacial reconstruction using both local reconstructive methods and microvascular free tissue transfer. A retrospective cohort study was designed, including patients who sustained self-inflicted gunshot wounds to the maxillofacial region between January 1, 2012 and May 1, 2020. Forty-one patients met the inclusion criteria. The majority of the patients were male (87.8%). Mean patient age was 44.2 ± 16.6 years. Alcohol or drugs, and a psychiatric history were present in a majority of the cases. The most involved anatomical region was the midface (75.6% of cases). Seven patients required free tissue transfer for reconstruction, with many needing multiple flaps. Self-inflicted gunshot wounds represent challenging reconstruction scenarios, often in the setting of severe psychological trauma, and require a multidisciplinary team to ensure the optimal outcome.

Abstract
The 1990s saw the rapid reemergence of malaria in Amazonia, where it remains an important public health priority in South America. The Amazonian International Center of Excellence in Malaria Research (ICEMR) was designed to take a multidisciplinary approach toward identifying novel malaria control and elimination strategies. Based on geographically and epidemiologically distinct sites in the Northeastern Peruvian and Western Brazilian Amazon regions, synergistic projects integrate malaria epidemiology, vector biology, and immunology. The Amazonian ICEMR's overarching goal is to understand how human behavior and other sociodemographic features of human reservoirs of transmission-predominantly asymptomatically parasitemic people-interact with the major Amazonian malaria vector, Nyssorhynchus (formerly Anopheles) darlingi, and with human immune responses to maintain malaria resilience and continued endemicity in a hypoendemic setting. Here, we will review Amazonian ICEMR's achievements on the synergies among malaria epidemiology, Plasmodium-vector interactions, and immune response, and how those provide a roadmap for further research, and, most importantly, point toward how to achieve malaria control and elimination in the Americas.

Abstract
Abstract
Background
Myocardial dysfunction is well established in systemic sclerosis (SSc). The utility of standard echocardiography is limited to detect the onset of myocardial dysfunction. Speckle tracking echocardiography (STE) and strain imaging has emerged as a useful technique to quantify left ventricle hemodynamics and myocardial function in early stages of myocardial dysfunction. We aimed to systematically analyze the existing literature on the application of STE and strain analysis in identifying SSc associated myocardial dysfunction
Methods
PubMed, Cochrane, and Google Scholar were queried for studies from the inception of the databases to 2022. Case control studies that used 2D STE for assessment of strain in SSc patients and controls, were included for the analysis. PRISMA guidelines were followed for selections of studies. Two independent reviewers extracted data. Analysis was done using Cochrane Review Manager 5.0.
Results
Total of 19 studies were included in the analysis that compared strain analysis in SSc patient's vs healthy controls. Of the 16 studies that reported left ventricular (LV) global longitudinal strain, we found significantly lower LV global longitudinal strain in SSc patients (mean difference 1.92; 95% CI 0.98–2.87). Six studies reported LV circumferential strain which was noted to be lower in SSc patients compared to healthy controls (mean difference 3.55; 95% CI 1.60–5.51). Five studies reported LV global radial strain with a similar decrease in radial strain among SSc patients compared to controls (mean difference 4.39; 95% CI −6.95 to −1.83). 10 studies reported right ventricular longitudinal strain with a decrease in longitudinal strain in SSc patient's vs controls (mean difference 2.57; 95% CI 2.03–3.12).
Conclusions
SSc patients have lower strain values compared to controls, which is suggestive of an impaired myocardial function in left and right ventricle. Strain analysis by STE could help with early detection of myocardial dysfunction.

Abstract
Introduction Herein, we tested the hypothesis that Asymptomatic P. vivax (Pv) infected individuals (Asym) feature different epidemiological, clinical and biochemical characteristics, as well as hematological parameters, potentially predictive of clinical immunity in comparison to symptomatic Pv infected individuals (Sym). Methodology Between 2018 - 2021, we conducted 11 population screenings (PS, Day 0 (D0)) in 13 different riverine communities around Iquitos city, in the Peruvian Amazon, to identify Pv Sym and Asym individuals. A group of these individuals agreed to participate in a nested case - control study to evaluate biochemical and hematological parameters. Pv Asym individuals did not present common malaria symptoms (fever, headache, and chills), had a positive/negative microscopy result, a positive qPCR result, reported no history of antimalarial treatment during the last month, and were followed-up weekly until Day 21 (D21). Control individuals, had a negative malaria microscopy and qPCR result, no history of antimalarial treatment or malaria infections during the last three years, and no history of comorbidities or chronic infections. Results From the 2159 individuals screened during PS, data revealed a low but heterogeneous Pv prevalence across the communities (11.4%), where most infections were Asym (66.7%) and submicroscopic (82.9%). A total of 29 Asym, 49 Sym, and 30 control individuals participated in the nested case - control study (n=78). Ten of the individuals that were initially Asym at D0, experienced malaria symptoms during follow up and therefore, were included in the Sym group. 29 individuals remained Asym throughout all follow-ups. High levels of eosinophils were found in Asym individuals in comparison to Sym and controls. Conclusion For the first-time, key epidemiological, hematological, and biochemical features are reported from Pv Asym infections from the Peruvian Amazon. These results should be considered for the design and reshaping of malaria control measures as the country moves toward malaria elimination.

Abstract
The ratio of the nucleon F_{2} structure functions, F_{2}^{n}/F_{2}^{p}, is determined by the MARATHON experiment from measurements of deep inelastic scattering of electrons from ^{3}H and ^{3}He nuclei. The experiment was performed in the Hall A Facility of Jefferson Lab using two high-resolution spectrometers for electron detection, and a cryogenic target system which included a low-activity tritium cell. The data analysis used a novel technique exploiting the mirror symmetry of the two nuclei, which essentially eliminates many theoretical uncertainties in the extraction of the ratio. The results, which cover the Bjorken scaling variable range 0.19<x<0.83, represent a significant improvement compared to previous SLAC and Jefferson Lab measurements for the ratio. They are compared to recent theoretical calculations and empirical determinations of the F_{2}^{n}/F_{2}^{p} ratio.

Abstract
Missing-mass spectroscopy with the 3H(e, e′K+) reaction was carried out at Jefferson Lab’s (JLab) Hall A in Oct–Nov, 2018. The differential cross section for the 3H(γ∗, K+)Λnn was deduced at ω = Ee − Ee′ = 2.102 GeV and at the forward K+-scattering angle (0° ≤ θγ∗K ≤ 5°) in the laboratory frame. Given typical predicted energies and decay widths, which are (BΛ, Γ) = (−0.25, 0.8) and (−0.55, 4.7) MeV, the cross sections were found to be 11.2 ± 4.8(stat.)+4.1−2.1(sys.) and 18.1 ± 6.8(stat.)+4.2−2.9(sys.) nb/sr, respectively. The obtained result would impose a constraint for interaction models particularly between Λ and neutron by comparing to theoretical calculations.

Abstract
We performed an experiment using tritium and hydrogen cryogenic gas targets at Thomas Jefferson National Accelerator Facility (JLab) in 2018 (E12-17-003)[1, 2]. In this article, we discuss the Λ/Σ0 hyperon electroproduction from hydrogen target. Elementary Λ/Σ0 hyperon production processes are important not only for an absolute mass scale calibration in our experiment, but also for the study of the electroproduction mechanisms themselves. In this article, we reported the results of the differential cross section for the p(e, e’K+)Λ/Σ0 reaction at Q2 ∼ 0.5 (GeV/c)2.

Abstract
BACKGROUND The goal of this study was to evaluate hard tissue response following guided bone regeneration using commercially available bovine bone grafts and collagen membranes; bilayer collagen membrane and porcine pericardium-based membrane, by means of a non-destructive three-dimensional (3D) computerized volumetric analysis following microtomography reconstruction. MATERIAL AND METHODS Bone regenerative properties of various bovine bone graft materials were evaluated in the Göttingen minipig model. Two standardized intraosseous defects (15mm x 8mm x 8mm) were created bilaterally of the mandible of eighteen animals (n=72 defects). Groups were nested within the same subject and randomly distributed among the sites: (i) negative control (no graft and membrane), (ii) bovine bone graft/bilayer collagen membrane (BOB) (iii) Bio-Oss® bone graft/porcine pericardium-based membrane (BOJ) and (iv) cerabone® bone graft/porcine pericardium-based membrane (CJ). Samples were harvested at 4, 8, and 12-week time points (n=6 animal/time point). Segments were scanned using computerized microtomography (μCT) and three dimensionally reconstructed utilizing volumetric reconstruction software. Statistical analyses were performed using IBM SPSS with a significance level of 5%. RESULTS From a temporal perspective, tridimensional evaluation revealed gradual bone ingrowth with the presence of particulate bone grafts bridging the defect walls, and mandibular architecture preservation over time. Volumetric analysis demonstrated no significant difference between all groups at 4 weeks (p>0.127). At 8 and 12 weeks there was a higher percentage of new bone formation for control and CJ groups when compared to BOB and BOJ groups (p<0.039). The natural bovine bone graft group showed more potential for graft resorption over time relative to bovine bone graft, significantly different between 4 and 8 weeks (p<0.003). CONCLUSIONS Volumetric analysis yielded a favorable mandible shape with respect to time through the beneficial balance between graft resorption/bone regenerative capacity for the natural bovine bone graft.

Abstract
We report the first measurement of the (e,e^{'}p) three-body breakup reaction cross sections in helium-3 (^{3}He) and tritium (^{3}H) at large momentum transfer [⟨Q^{2}⟩≈1.9 (GeV/c)^{2}] and x_{B}>1 kinematics, where the cross section should be sensitive to quasielastic (QE) scattering from single nucleons. The data cover missing momenta 40≤p_{miss}≤500 MeV/c that, in the QE limit with no rescattering, equals the initial momentum of the probed nucleon. The measured cross sections are compared with state-of-the-art ab initio calculations. Overall good agreement, within ±20%, is observed between data and calculations for the full p_{miss} range for ^{3}H and for 100≤p_{miss}≤350 MeV/c for ^{3}He. Including the effects of rescattering of the outgoing nucleon improves agreement with the data at p_{miss}>250 MeV/c and suggests contributions from charge-exchange (SCX) rescattering. The isoscalar sum of ^{3}He plus ^{3}H, which is largely insensitive to SCX, is described by calculations to within the accuracy of the data over the entire p_{miss} range. This validates current models of the ground state of the three-nucleon system up to very high initial nucleon momenta of 500 MeV/c.

Abstract
Abstract
Background In Arizona, female breast cancer has the highest incidence rate and the second highest death rate compared to all other cancers. This ongoing single arm intervention study investigates non-adherence with recommended annual mammography or follow-up breast imaging. Data collected for this study is both retrospective, using the university Electronic Health Record (EHR) system (January 1, 2014 to September 30, 2017), and prospective, implementing a questionnaire during the intervention phase. Potential study participants were identified using EHR and categorized by BI-RADS (Breast Imaging-Reporting and Data System) 0 to 5. With IRB approval from University of Arizona, we designed a questionnaire to measure barriers to adherence and we navigate participants to schedule and attend follow-up appointments. This study's overall specific aims are to increase first time mammography screening by 25% among women in Southern Arizona; increase adherence or repeat screening rate by 20% among women lost to follow-up; establish the framework for a community- academic partnership in ethnically diverse areas. Women, age 40 and older who are not compliant with recommended annual mammograms or recommended follow-up screenings after a suspicious finding are eligible to participate in this study. Men and children, as well as women for whom breast imaging is not recommended are excluded from participating in this study. Results Patient's age was summarized by mean ± standard deviation for continuous variables and frequency and the associated percentage for categorical variables. BI-RADS scores were classified into Negative, Benign, Possible Malignancy and Proven Malignancy and compared between ethnic and racial groups using Fisher's exact test. Of 8823 non-compliant woman over nearly 4 years of data, 0.2% are BI-RADS 4 and 5, 2.2% are BI-RADS 3, 96% are BI-RADS 1 and 2, and 0.3% are BI-RADS 0. The mean age is 61.59 years, with 25% reporting as Hispanic, 66% reporting as non-Hispanic women (NHW), and 10% preferring to receive care in Spanish. Initial data shows only .24% with proven malignancies. Further, the data reveals that Hispanics have a slightly higher rate of possible malignancy (.36%) than NHW (.18%); however, NHW show a slightly higher rate of proven malignancy (.27% compared to .18%, respectively). Discussion These data provide valuable information for the direction of this study; in particular, understanding the disparity between Hispanic and NHW malignancies and developing culturally competent interventions and education materials to increase compliance with breast cancer screening recommendations. Further, these data indicate our focus should be on screening compliance for BI-RADS 1 and 2. These data also point to a possible high non-compliance issue. Comparing non-compliance data from other regional clinics will continue to shape this study's direction. The target sample size for this study is 300 participants. We accept a 95% confidence level and a 5% margin of error. Out of 420 recruitment letters mailed, the navigators have reached 152 potential participants by phone and have a 26% study recruitment rate (n=40).

Abstract
The Spin Asymmetries of the Nucleon Experiment measured two double spin asymmetries using a polarized proton target and polarized electron beam at two beam energies, 4.7 and 5.9 GeV. A large-acceptance open-configuration detector package identified scattered electrons at 40° and covered a wide range in Bjorken x (0.3<x<0.8). Proportional to an average color Lorentz force, the twist-3 matrix element, d[over ˜]_{2}^{p}, was extracted from the measured asymmetries at Q^{2} values ranging from 2.0 to 6.0 GeV^{2}. The data display the opposite sign compared to most quark models, including the lattice QCD result, and an unexpected scale dependence. Furthermore, when combined with the neutron data in the same Q^{2} range the results suggest a flavor independent average color Lorentz force.
