Abstract
BACKGROUND Mitral annulus calcification (MAC) represents a degenerative process resulting in calcium deposition in the mitral valve apparatus. Mitral annulus calcification is associated with adverse clinical outcomes. We sought to examine the long-term significance of mild MAC and its relationship to subsequent mitral valve dysfunction (MVD) and mortality in patients without MVD on the initial echocardiogram. METHODS A total of 1,420 patients with mild MAC and no MVD at baseline and 1 or more follow-up echocardiograms at least 1 year after the baseline echocardiogram were included in the analysis. For patients with >1 echocardiogram during follow-up, the last echocardiogram was used. The same criteria were used to identify 6,496 patients without MAC. Mitral valve dysfunction was defined as mitral regurgitation (MR) and/or mitral stenosis (MS) of moderate or greater severity. Mixed disease was defined as the concurrent presence of both moderate or greater MS and MR. The primary end point was development of MVD, and the secondary end point was all-cause mortality. RESULTS For patients with mild MAC, age was 74 ± 10 years and 528 (37%) were female. Over a median follow-up of 4.7 (interquartile range, 2.7-6.9) years, 215 patients with mild MAC developed MVD, including MR in 170 (79%), MS in 37 (17%), and mixed disease in 8 (4%). In a multivariable regression model compared to patients without MAC, the presence of mild MAC was independently associated with increased mortality (hazard ratio = 1.43; 95% CI 1.24, 1.66; P < .001). Kaplan-Meier 4-year survival rates were 80% and 90% for patients with mild MAC and no MAC, respectively. CONCLUSIONS Mild MAC observed on transthoracic echocardiography is an important clinical finding with prognostic implications for both valvular function and mortality.

Abstract
Hypertrophic cardiomyopathy (HCM), the most common inherited cardiomyopathy, exhibits left ventricular hypertrophy not secondary to other causes, with varied phenotypic expression. Enhanced actin-myosin interaction underlies excessive myocardial contraction, frequently resulting in dynamic obstruction within the left ventricle. Left ventricular outflow tract obstruction, occurring at rest or with provocation in 75% of HCM patients, portends adverse prognosis, contributes to symptoms, and is frequently a therapeutic target. Transthoracic echocardiography plays a crucial role in the screening, initial diagnosis, management, and risk stratification of HCM. Herein, we explore echocardiographic evaluation of HCM, emphasizing Doppler assessment for obstruction. Echocardiography informs management strategies through noninvasive hemodynamic assessment, which is frequently obtained with various provocative maneuvers. Recognition of obstructive HCM phenotypes and associated anatomical abnormalities guides therapeutic decision-making. Doppler echocardiography allows monitoring of therapeutic responses, whether it be medical therapies (including cardiac myosin inhibitor therapy) or septal reduction therapies, including surgical myectomy and alcohol septal ablation. This article discusses the hemodynamics of obstruction and practical application of Doppler assessment in HCM. In addition, it provides a visual atlas of obstruction in HCM, including high-quality figures and complementary videos that illustrate the many facets of dynamic obstruction.

Abstract
Background Primary cardiac soft tissue sarcomas (CSTS) affect young adults, with dismal outcomes. Objectives The aim of this study was to investigate the clinical outcomes of patients with CSTS receiving immune checkpoint inhibitors (ICIs). Methods A retrospective, multi-institutional cohort study was conducted among patients with CSTS between 2015 and 2022. The patients were treated with ICI-based regimens. The Kaplan-Meier method was used to estimate overall survival (OS) and progression-free survival (PFS). Objective response rates were determined according to Response Evaluation Criteria in Solid Tumors version 1.1. Treatment-related adverse events were graded per the Common Terminology Criteria for Adverse Events version 5.0. Results Among 24 patients with CSTS, 17 (70.8%) were White, and 13 (54.2%) were male. Eight patients (33.3%) had angiosarcoma. At the time of ICI treatment, 18 patients (75.0%) had metastatic CSTS, and 4 (16.7%) had locally advanced disease. ICIs were administered as the first-line therapy in 6 patients (25.0%) and as the second-line therapy or beyond in 18 patients (75.0%). For the 18 patients with available response data, objective response rate was 11.1% (n = 2 of 18). The median PFS and median OS in advanced and metastatic CSTS (n = 22) were 5.7 months (95% CI: 2.8-13.3 months) and 14.9 months (95% CI: 5.7-23.7 months), respectively. The median PFS and OS were significantly shorter in patients with cardiac angiosarcomas than in those with nonangiosarcoma CSTS: median PFS was 1.7 vs 11 months, respectively (P < 0.0001), and median OS was 3.0 vs 24.0 months, respectively (P = 0.008). Any grade treatment-related adverse events occurred exclusively in the 15 patients with nonangiosarcoma CSTS (n = 7 [46.7%]), of which 6 (40.0%) were grade ≥3. Conclusions Although ICIs demonstrate modest activity in CSTS, durable benefit was observed in a subset of patients with nonangiosarcoma, albeit with higher toxicity.

Abstract
BACKGROUND Amyloidosis is a common comorbidity in elderly patients with aortic stenosis (AS) referred for transcatheter aortic valve replacement (TAVR). This study aims to assess the impact of amyloidosis on the clinical outcomes of TAVR. METHODS This is a retrospective study of the National Inpatient Sample database that identified adult patients (≥18 years) with AS hospitalized for TAVR from 2016 through 2020 to compare outcomes in those with versus without amyloidosis. Our primary outcome was in-hospital mortality. Secondary outcomes included procedural complications, hospital length of stay (LOS), and total costs. TAVR trends in both cohorts were also evaluated. RESULTS The total cohort included 304,710 patients with AS undergoing TAVR, of whom 410 had amyloidosis. Over the study period, TAVR trends increased significantly in patients with and without amyloidosis (both ptrend < 0.01). Patients with amyloidosis were more likely to be older males with atrial fibrillation/flutter, congestive heart failure, renal disease, and dementia compared to non-amyloidosis patients. After adjustment for baseline characteristics, patients with amyloidosis had similar odds of in-hospital mortality (adjusted odds ratio [aOR] 1.66, 95 % confidence interval [CI] 0.34-3.63), heart block (aOR 1.33, 95 % CI 0.84-2.10), permanent pacemaker insertion (aOR 0.67, 95 % CI 0.27-1.66), stroke (aOR 0.90, 95 % CI 0.32-3.13), acute kidney injury, major bleeding, blood transfusion, vascular complications, in addition to similar LOS (p = 0.21) and total costs (p = 0.18) compared to patients without amyloidosis. CONCLUSION In patients with AS undergoing TAVR, comorbid amyloidosis is associated with similar in-hospital mortality and procedural complications compared to patients without amyloidosis.

Abstract
An experiment was conducted to evaluate the effect of copper oxide (Cu2O) and potentiated zinc oxide (ZnO) on performance, intestinal morphology, oocyst excretion, coccidial lesion scores, and antioxidant properties in broilers during an Eimeria spp. challenge. A total of 288 1-day-old male broiler chickens (Ross 308) were divided into 18 treatments. Treatments included three levels of Cu (0, 15, or 150 mg/kg) from Cu2O and three levels of Zn (0, 80, or 160 mg/kg) from potentiated ZnO which were added to the basal diet and fed to broilers with or without challenge, using a completely randomized design in a factorial arrangement for 42 days. Live body weight, feed intake, mortality, and the cause of death were recorded weekly and histomorphology of jejunum was measured at the end of the experiment. Results showed that birds fed Cu and Zn linearly decreased (P < 0.0001) oocyst shedding. The number of excreted oocysts was reduced eight times in broilers fed a diet containing 150 mg/kg copper from Cu2O and 160 mg/kg zinc from potentiated ZnO, compared to the infected group without Cu and Zn supplementation (P < 0.0001). Microscopic features of both non-challenged and challenged broiler jejunum revealed significant improvement along with increased Cu2O and potentiated ZnO doses. Supplementation of Cu2O and potentiated ZnO decreased the jejunum structure damages and intestinal lesion score (P < 0.002). Eimeria caused a decrease (P < 0.006) in total antioxidant capacity. Superoxide dismutase increased by dietary zinc supplementation (P < 0.05). Results suggested that a combination of Cu2O and potentiated ZnO could exhibit efficient anticoccidial activity.

Abstract
BackgroundDermatomyositis (DM) patients have fewer risks of COVID-19 infection compared to the general population, however, certain subgroups with DM have worse outcomes. Men. African Americans, those with interstitial lung disease, exhibited higher risks of severe COVID-19. DMARD and glucocorticoid use was associated with frequent hospitalisations and severe sepsis.ObjectivesRheumatic diseases (RDs) like DM, are previously known to be vulnerable towards various types of infections due to its aggressive activity mandating high dose immunosuppressive therapy. The severity of COVID-19 in RDs is limited in literature due to the heterogeneous nature of the condition. Therefore, specific details on mortality is essential to navigate any precautions required in the treatment.MethodsRetrospective data of individuals with DM and COVID-19 and the general population with COVID-19 between January 2020 to August 2020 was retrieved from the TriNetX database. A one-to-one matched COVID-19 positive control was selected using propensity score (PS) matching. We assessed COVID-19 outcomes such as mortality, hospitalisation, ICU admission, severe COVID-19, mechanical ventilation (MV), acute kidney injury (AKI), venous thromboembolism (VTE), ischemic stroke, acute respiratory distress syndrome (ARDS), renal replacement therapy (RRT) and sepsis. Subgroup analyses included gender, race, ILD, cancer patients, disease-modifying rheumatic drugs (DMARDs) use, and glucocorticoids (GC) use (Figure 1).Figure 1.Overview of studyResultsWe identified 5,574 DM patients with COVID-19, and 5,574 general population with COVID-19 (controls).

Abstract
The current trial was conducted by using the 288 Japanese quails to evaluate the effects of a zinc-deficient diet supplemented with nano and micro zinc oxide on performance, fertility, hatchability, and egg quality characteristics. In this experiment, birds were randomly allocated to 9 dietary treatments includes diets supplemented with nano or micro particles of zinc oxide (amount of ZnO supplement for each treatment) to supply 49, 74, 99, and 124 mg zinc per kilogram of diet in a factorial arrangement (2 × 4) and a control non supplemented diet (24 mg/kg) with four replicates of eight birds (six females and two males) in each pen. Birds were fed the experimental diets from 47 to 75 days of age and had free access to water and feed during the experimental period. Results showed that Zn supplementation, regardless of particle size, improved the eggshell thickness (P < 0.01). A significant (P < 0.05) interaction was observed between zinc level and ZnO particle size for Shell breaking strength. Quails fed diets supplement with ZnO showed significantly higher egg weight and eggshell surface (P < 0.05) as compared with birds fed a non-supplemented control diet. Results obtained here showed that supplementation of nano ZnO enhanced fertility considerably. Application of non-linear quadratic models showed that the maximum egg production percentage was achieved when 67 or 72 mg/kg of dietary zinc was supplied from nano and micro ZnO, respectively. This result indicated that nano ZnO could reduce the zinc requirement in laying Japanese quail.

Abstract
Purpose Coronavirus Disease 19 (COVID-19) is a novel cause of end-stage fibrotic lung disease. Data has been limited to case series and single center reports with regards to outcomes in this unique cohort of patients. We sought to investigate the largest experience to date in patients with COVID-19 fibrosis (CVF) who underwent lung transplantation. Methods The United Network for Organ Sharing (UNOS) database was queried for all adult patients (≥18 years old) who underwent isolated lung transplantation between 2018 and July 2021. Recipients diagnosed with CVF were identified and compared to those with idiopathic pulmonary fibrosis (IPF). The IPF cohort included recipients from 2018, in the pre-COVID era. Baseline demographics, perioperative factors, and 30-day outcomes were examined. Results A total of 931 recipients were included in this study, 868 (93.2%) and 63 (6.8%) were IPF and CVF, respectively. IPF recipients were on average older (65 vs. 56 years, p<0.001), white race (83% vs. 51%, p<0.001), and less likely to be male (73% vs. 86%, p=0.04). BMI was similar between the IPF and CVF, 27.6 and 27.2 kg/m2, as was the mean PAP 24 and 21 mmHg. The CVF cohort had lower predicted FVC (32% vs. 47%, p=0.01), and had less tobacco use (36% vs 61%, p<0.001). Mean creatinine level was clinically similar, though statistically higher in the IPF cohort, (0.83 vs 0.64, p<0.001). CVF recipients were on the waitlist for a shorter median duration (10 vs 32 days, p<0.001) with a higher LAS (85 vs 41, p<0.001). Notably, more CVF recipient were be on ECMO at time of listing (29% vs 2%, p<0.001) and require ventilatory support (27% vs. 2%, p<0.001). CVF recipients were more likely to receive a double lung transplantation compared to IPF (83% vs 64%, p=0.002), with similar ischemia times, 5.5 vs 5.1 hrs (p=0.17). Mortality at 30 days was comparable between CVF and IPF (7.0% vs. 2.3%, p=0.09), though 20 patients in the CVF cohort had missing data. Conclusion Patients with end-stage lung disease secondary to CVF are higher acuity, and more likely to require ECMO and ventilatory support as a bridge to lung transplantation. Early mortality, while comparable to non-COVID related fibrotic lung disease, remains almost 3 times higher with CVF. In the era of publicly reported survival outcomes, the transplant community may need to reconsider how we approach this new and devastating diagnosis of CVF.

Abstract
Endovascular treatment of aneurysms with flow diverters or coiling is sometimes complicated by intraprocedural or postprocedural thrombosis along or within the devices. Thrombus composition and structure associated with such complications may provide insights into mechanisms of thrombus formation and clinical strategies to remove the thrombus. We present a retrospective histopathologic study of 4 patients who underwent mechanical thrombectomy due to acute occlusion of either implanted flow diverter devices or along coils during the treatment of intracranial aneurysm.

Abstract
BACKGROUND AND PURPOSE Aspiration thrombectomy has become a preferred approach to recanalize large-vessel occlusion in stroke with a growing trend toward using larger-bore catheters and stronger vacuum pumps. However, the mechanical response of the delicate cerebral arteries to aspiration force has not been evaluated. Here, we provide preclinical and clinical evidence of intracranial arterial collapse in aspiration thrombectomy. MATERIALS AND METHODS We presented a clinical case of arterial collapse with previously implanted flow diverters. We then evaluated the effect of vacuum with conventional aspiration catheters (with and without stent retrievers) in a rabbit model (n = 3) using fluoroscopy and intravascular optical coherence tomography. Then, in a validated human cadaveric brain model, we conducted 168 tests of direct aspiration thrombectomy following an experimental design modifying the catheter inner diameter (0.064 inch, 0.068 inch, and 0.070 inch), cerebral perfusion pressures (mean around 60 and 90 mm Hg), and anterior-versus-posterior circulation. Arterial wall response was recorded and graded via direct transluminal observation. RESULTS Arterial collapse was observed in both the patient and preclinical experimental models. In the human brain model, arterial collapse was observed in 98% of cases in the M2 and in all the cases with complete proximal flow arrest. A larger bore size of the aspiration catheter, a lower cerebral perfusion pressure, and the posterior circulation in comparison with the anterior circulation were associated with a higher probability of arterial collapse. CONCLUSIONS Arterial collapse does occur during aspiration thrombectomy and is more likely to happen with larger catheters, lower perfusion pressure, and smaller arteries.

Abstract
AbstractHuman factors are one of the main reasons for structural damage as they decrease the bearing capacity and also lead to an inaccurate estimation of the structure. Previous studies show that the use of CFRP in the damaged structures can significantly increase their bending and shear capacity. This study examines the capacity and cracks distribution in eight RC (reinforced concrete) beams (210 × 250 × 250 cm), each of which was rehabilitated with seven CFRP (carbon fiber-reinforced polymer) strips using the strip method. Each beam, except for the control specimen, experiences different types of concrete and rebar damages, which are finally compared with those of the control specimen. The results indicated that rebar damage in all the beams was significant and the effects of concrete damage were minimized by CFRP strips. Moreover, the force–displacement diagrams indicate the greatest force for the control specimen. Other specimens reached up to 80% of the force experienced by the control specimen. Finally, the parametric study showed that the influence of the crack width on decreasing the bearing capacity was more significant compared with the other parameters.

Abstract
BACKGROUND AND PURPOSE Hydrophilic polymers and polytetrafluoroethylene liners, commonly used in the construction of endovascular devices, occasionally separate from devices with subsequent embolization. We determined the frequency of such materials in thrombus specimens retrieved by mechanical thrombectomy in patients with stroke. MATERIALS AND METHODS We retrospectively reviewed H&E-stained thrombus sections for presence and types of foreign materials. We identified 4 types of foreign materials-Type I: material was light green with refraction and had a homogeneous texture; type II: material was light gray and/or dark gray, thin, and loose or attenuated in texture; type III: material was light green with refraction, solitary in texture, irregular in shape, and was often associated with round or oval bubblelike particles and/or diffuse black particles; and type IV: material had homogeneous texture and was light pink or red. In addition, polymer materials from different layers of used mechanical thrombectomy catheters were compared with the foreign materials found in thrombus specimens. RESULTS A total of 101 thrombi were evaluated. Foreign materials were found in 53 (52.5%) thrombus samples. The most common type was type I (92%), followed by type II (30%). The histopathologic features of the polymer materials from mechanical thrombectomy catheters were similar to the foreign materials found in thrombus specimens. The inner polytetrafluoroethylene liner and coating layer of catheters resembled type I and type II of the foreign materials, respectively. CONCLUSIONS Foreign polymer materials are present in approximately half of retrieved thrombi, most commonly polytetrafluoroethylene from catheter liners and less from hydrophilic coatings.

Abstract
BACKGROUND AND PURPOSE Previous studies have successfully created blood clot analogs for in vitro endovascular device testing using animal blood of various species. Blood components vary greatly among species; therefore, creating clot analogs from human blood is likely a more accurate representation of thrombi formed in the human vasculature. MATERIALS AND METHODS Following approval from the Mayo Clinic institutional review board, human whole-blood and platelet donations were obtained from the blood transfusion service. Twelve clot analogs were created by combining different ratios of red blood cells + buffy coat, plasma, and platelets. Thrombin and calcium chloride were added to stimulate coagulation. Clot composition was assessed using histologic and immunohistochemical staining. To assess the similarities of mechanical properties to patient clots, 3 types of clot analogs (soft, elastic, and stiff) were selected for in vitro thrombectomy testing. RESULTS The range of histopathologic compositions produced is representative of clots removed during thrombectomy procedures. The red blood cell composition ranged from 8.9% to 91.4%, and fibrin composition ranged from 3.1% to 53.4%. Platelets (CD42b) and von Willebrand Factor ranged from 0.5% to 47.1% and 1.0% to 63.4%, respectively. The soft clots had the highest first-pass effect and successful revascularization rates followed by the elastic and stiff clots. Distal embolization events were observed when clot ingestion could not be achieved, requiring device pullback. The incidence rate of distal embolization was the highest for the stiff clots due to the weak clot/device integration. CONCLUSIONS Red blood cell-rich, fibrin-rich, and platelet-rich clot analogs that mimic clots retrieved from patients with acute ischemic stroke were created in vitro. Differing retrieval outcomes were confirmed using in vitro thrombectomy testing in a subset of clots.

Abstract
Cardiotoxicity is a well-established complication of multiple cancer therapeutics, and the one of the most prominent effects that limits the use of these agents is in the form of left ventricular dysfunction, otherwise known as chemotherapy-induced cardiomyopathy (CIMP). Because CIMP can worsen patient outcomes and interfere with a patient's life-saving cancer treatments, it is important to implement a monitoring strategy for patients undergoing potentially cardiotoxic treatments. Efforts have been made by multiple societies to provide recommendations for screening and monitoring for CIMP in at-risk patients, with slight variations between guideline documents and expert consensuses. Most of the recommendations for monitoring for CIMP are specific to anthracyclines and the human epidermal growth factor receptor 2-antagonist trastuzumab, with very limited guidance for other cardiotoxic agents such as Tyr kinase inhibitors and proteasome inhibitors, which we cover in this article. Echocardiography remains the mainstay for imaging surveillance because of its safety profile and widespread availability, but the accuracy of cardiac magnetic resonance imaging (CMR) makes it an important modality when there are discrepancies in left ventricular ejection fraction assessment. Subclinical cardiotoxicity may be detected using laboratory biomarkers such as cardiac troponin and brain natriuretic peptide as well as myocardial deformation (strain) imaging by echocardiography or CMR. Specific recommendations for timing and frequency of laboratory biomarker assessment remain up for debate, but myocardial deformation imaging should be performed with every echocardiogram or CMR assessment. Future studies are needed to evaluate the efficacy of established surveillance recommendations and to develop specific recommendations for novel cancer therapeutics.

Abstract
Recent quantitative approaches for studying several aspects of urban life and infrastructure have shown that scale properties allow the understanding of many features of urban infrastructure and of human activity in cities. In this paper, we show that COVID-19 virus contamination follows a similar pattern in different regions of the world. The superlinear power-law behavior for the number of contamination cases as a function of the city population, with exponent β of the order of 1.15 is always obtained. Due to the strong indication that scaling is a determinant feature of covid-19 spread, we propose an epidemiological model that embodies a fractal structure, allowing a more detailed description of the observed data about the virus spread in different countries and regions. The hypothesis that fractal structures can be formed in cities as well as in larger networks is tested, indicating that indeed self-similarity may be found in networks connecting several cities.

Abstract
IntroductionAlthough spiritual care is commonly regarded as a nursing task, in practice, it is often provided inadequately.ObjectiveThe purpose of this study was to examine relationship between attitude toward spirituality and the attitude and performance of spiritual care among nurses who working in hospitals of Iran university of medical sciences.MethodsThis was a correlative-descriptive study. Spiritual Perspective Scale (SPS) and Nursing Spiritual Care Perspective Scale (NSCPS) were used to gather the data. A number of 166 nurses participated in this study.ResultsFindings showed that of nurses’ spirituality attitude score was 4.98 ± 1.1 which indicated high attitude toward spirituality. The total average of nurses’ attitude about spiritual practices was 3.67 ± 0.51, which signified the positive attitude of nurses about spiritual practices. Findings revealed that positive spiritual attitude had a significant correlation with 6 out of 12 expressed spiritual interventions. In addition, spiritual attitude generally had a significant positive correlation with spiritual interventions. The positive spiritual attitude had a significant correlation with only 3 items out of 11 for the attitude toward spiritual practices. There was no correlation between spiritual attitude and the attitude toward spiritual practices.ConclusionIn spite of the positive attitude, nurses did not perform half of the spiritual interventions which most of them were in line with fulfilling the patients’ religious needs. Establishment of in-service education program regarding spiritual care practice by role play and modeling methods are recommended.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
OBJECTIVE Diagnostic accuracy of myocardial perfusion imaging (MPI) is not optimal to predict the result of angiography. The current study aimed at investigating the application of artificial neural network (ANN) to integrate the clinical data with the result and quantification of MPI. METHODS Out of 923 patients with MPI, 93 who underwent angiography were recruited. The clinical data including the cardiac risk factors were collected and the results of MPI and coronary angiography were recorded. The quantification of MPI polar plots (i.e. the counts of 20 segments of each stress and rest polar plots) and the Gensini score of angiographies were calculated. Feed-forward ANN was designed integrating clinical and quantification data to predict the result of angiography (normal vs. abnormal), non-obstructive or obstructive coronary artery disease (CAD), and Gensini score (≥10 and <10). The ANNs were designed to predict the results of angiography using different combinations of data as follows: reports of MPI, the counts of 40 segments of stress and rest polar plots, and the count of these 40 segments in addition to age, gender, and the number of risk factors. The diagnostic performance of MPI with different ANNs was compared. RESULTS The accuracy of MPI to predict the result of angiography, obstructive CAD, and Gensini score increased from 81.7% to 92.9%, 65.0% to 85.7%, and 50.5% to 92.9%, respectively by ANN using counts and clinical risk factors. CONCLUSION The diagnostic accuracy of MPI could be improved by ANN, using clinical and quantification data.

Abstract
The study of the standard formation enthalpy, entropy, and heat capacity for key species relevant to the low-temperature combustion of cyclohexane has been performed by applying the group additivity method of Benson. The properties of 18 Benson groups (8 of them for the first time), and 10 ring correction factors for cyclic species were estimated through different empirical and semi-empirical methods. The method validation proceeded through comparison of predicted values for certain number of newly estimated groups and available literature data derived from quantum chemistry estimations. Further validations of the estimated properties of groups have been provided by comparing estimated properties of test species with data in literature and kinetic databases. Also the standard deviation between prediction and reported values has been evaluated for each validation case. A similar approach has been applied for validation of the estimated ring correction groups. For selected well-studied cyclic molecules the predicted values and the literature data have been compared with each other, and the standard deviations have been also reported. The evaluated properties of the cyclohexane relevant species were also compared with similar ones available in other kinetic models and in databases. At the end the estimated properties have been presented in a tabulated form of NASA polynomial coefficients with extrapolation up to 3500 K.

Abstract
OBJECTIVES Given the increasing threats of communicable and non-communicable diseases, it is necessary for policy-makers and public health (PH) professionals to address ethical issues in health policies and plans. This study aimed to develop a practical framework for the ethical evaluation of PH programs. STUDY DESIGN A multidisciplinary team developed an ethical framework to evaluate PH plans from 2015 to 2017. METHODS In this study, the multi-method approach was used. First, a list of moral norms in PH policy and practice was drafted and completed in two interactive sessions. Then, the Delphi method was used for consensus about the structural components to be adopted in the framework. After developing the framework, its efficiency was assessed by evaluating Iran's Fourth Strategic Plan for HIV/AIDS Prevention and Control. RESULTS The framework was developed in the following three sections: (i) determination of the general moral norms in PH practice and policy; (ii) five steps of evaluation; and (iii) a procedural evaluation step to ensure fair decision-making. The ratio of the ethical points of the PH plan increased by 46% after implementation of the framework, and the frequency of ethical points increased significantly after applying the framework (P = 0.001). CONCLUSION The application of the framework for the ethical evaluation of various PH programs ensures a comprehensive and scientific-deliberative decision-making process, while also contributing to the development of the framework.
