Abstract
Abstract
Background
Non-small-cell lung cancer (NSCLC) is the first cause of cancer-related death among men and the second among women worldwide. It also poses an economic threat to the sustainability of healthcare services. This study estimates the direct costs of care for patients with NSCLC by stage at diagnosis and management phase of pathway recommended in local and international guidelines.
Methods
Based on the most up-to-date guidelines we developed a detailed “whole-disease” model that lists the probabilities of all potentially necessary diagnostic and therapeutic actions involved in the management of each stage of NSCLC. Then we assigned the cost sustained by the public authorities to each procedure, obtaining an estimate of the total and average per-patient costs of each stage of the disease and management phase in Veneto Region, Italy.
Results
The mean expected cost of a patient with NSCLC is 22,968 € in the first year: 20,222 € in stage I, 23,935 € in stage II, 23,027 € in stage III, 22,915 € in stage IV and 31,749 € for Pancoast's tumors. In the second year the mean per patient-costs patient ranged from 2,722 €, for a patient with stage I disease, to 13,396 € for a patient with stage IV, with an overall average cost of 8,307 €. In the early stages, the main cost was due to surgery, whereas in the more advanced stages radiotherapy, medical therapy, treatment for progressions and supportive care become variously more important.
Conclusions
Our study enabled a prediction of the direct costs and outcomes for patients diagnosed with NSCLC on a two-year timeline after the diagnosis. An estimation of the direct costs of NSCLC, and in general for cancer, appears fundamental to predict the burden of new oncological therapies and treatments on healthcare services, and, in our opinion, our model could represent a useful tool for policy-makers in the optimization of resources allocation.
Key messages
Whole disease model allows an economic evaluation of a clinical pathway. The model is able to estimate direct costs of NSCLC by disease stage and management phase within a time horizon of two years. High cost-surgery makes the early stages no less expensive than advanced stages during the first year. In the second year, an advanced stage case costs almost five times more than an early stage case.

Abstract
Seizure threshold 2 (SZT2) gene mutations have been associated with developmental and epileptic encephalopathies (DEEs). Following a literature review, we collected 22 patients and identified the main clinical features related to SZT2 variants that are epilepsy with onset within the first years of life, intellectual disability (ID), macrocephaly with dysmorphic facial features, corpus callosum (CC) shape abnormalities, and cortical migration disorders. Moreover, we identified the c.7825T>G homozygous missense variant in SZT2 in two female siblings presenting with focal seizures, mild-moderate ID, behavioral disturbances, and facial dysmorphisms. Interictal Electroencephalogram (EEG) and ictal EEG were both informative and revealed, respectively, temporal bilateral asynchronous slow and epileptiform abnormalities and a focal onset in both of them. Neuroimaging study revealed a thick and abnormally shaped CC. Seizure threshold 2 has been identified as a component of the KICSTOR complex, a newly recognized protein complex involved in the mammalian target of rapamycin (mTOR) pathway. mTOR signaling dysregulation represents common pathogenetic mechanisms that can explain the presence of both epileptogenesis and ID. Even if few cases had been reported, a new clinical phenotype is emerging, and recent hypothesis of hyperactivation of mTORC1 signaling might also open to targeted treatments, challenging an early diagnosis as of paramount importance.

Abstract
Background:Most autoimmune diseases are more prevalent in women. Symptom severity, disease progression, response to therapy and overall survival differ between males and females with rheumatic diseases.Objectives:To identify the characteristics of autoimmune diseases presentation and treatment between male and female population using information from the Mexican Adverse Events Registry (BIOBADAMEX).Methods:BIOBADAMEX is a Mexican ongoing cohort that collects the information of patients using biologic and biosimilar drugs since 2016. For this study we included all patients enrolled in the registry and compared baseline clinical and disease characteristics, treatment and presence of adverse events between genders. We used logistic regression to analyze univariable associations.Results:A total of 655 participants were analysed, of which 82% were female (Table 1). We found women were older with a median of 53 years compared to 46 years in men (OR 1.02, CI 1.0-1.1). Smoking was higher in men (16%) compared to women (5%), (OR 0.3, CI 0.2-0.6). Women had longer disease duration, 9 years compared to 7 years in men (OR 1, CI 1.0-1.1). Rheumatoid arthritis (RA) was more prevalent in women (OR 2.7, CI 1-6.9), while ankylosing spondylitis (AS) and psoriatic arthritis (PsA) were more prevalent in men (OR 0.2, CI 0.1-0.4, and OR 0.3, CI 0.1-0.9 respectively). Women had more comorbidities than men (OR 1.8, CI 1.1-2.8) and used steroids more frequently (OR 1.7, CI 1.1-2.7). Differences in disease activity were not found, however we noticed high activity scores among participants.Table 1.Baseline characteristics in the cohort by sexWomenn=532 (82%)Menn=123 (18%)UnivariableaOR(95%CI)Age, median (IQR)53 (44-60)47 (34-55)1.02 (1.0-1.1)*Body Mass Index, median (IQR)27 (23-31)26 (23-30)1.0 (0.9-1.1)Smoking, n(%)28 (5)18 (16)0.3 (0.2- 0.6)*Disease duration, median (IQR)9 (4-16)7 (2-13)1.0 (1.0-1.1)*Diagnosis, n(%): RA414 (78)37 (30)2.4 (1.0-5.7)* AIJ12 (2)5 (4)0.5 (0.1-1.9) AS37 (7)56 (46)0.1 (0.1-0.4)* PsA19 (4)15 (12)0.3 (0.1-0.8)* SLE17 (3)3 (2)1.2 (0.3-5.2) Others33 (6)7 (6)1Disease Activity indexes, median (IQR) DAS28a4.9 (3.6-5.9)4.9 (3.0-5.9)1.1 (0.9-1.3) BASDAIb4.8 (2.9-8)5.3 (2.8-7.5)0.9 (0.8- 1.1) ASDASc3.2 (1.9-4.5)3.9 (2.5-4.7)0.8 (0.6-1.2) SLEDAId14.5 (5.0-19.5)25 (25.0-31.0)0.6 (0.4-1.1)High blood pressure, n(%)77 (15)14 (12)1.3 (0.7-2.4)Diabetes mellitus, n(%)46 (9)7 (6)1.5 (0.7-3.5)High cholesterol, n(%)41 (8)8 (7)1.2 (0.4-2.6)Other comorbidities, n(%):173 (33)26 (21)1.8 (1.1 -2.8)*Use of previous biologic, n(%):216 (40)44 (36)1.2 (0.8- 1.8)Use of steroids, n(%):215 (42)34 (29)1.7 (1.1 -2.7)*Use of DMARD, n(%):418 (79)89 (72)1.4 (0.9-2.2)Adverse eventsb, n(%):69 (13)14 (11)1.2 (0.7-2.1) Severeb, n(%):12 (17)3 (21)0.8 (0.2-3.1)Univariable logistic regression analysis. *p<0.05.an=469,bn=99,cn=71,dn=19,Table 1.Analysis of association between change (Δ) in FMD and relevant parameters by univariate and multivariate linear regression analysis.UnivariateRho (p)MultivariateBeta (p)Δ FMD (%)(r2=0.30)ChangeADMA (µmol/l)-0.63 (<0.001)-0.25 (0.01)MDA (nmol/ml)-0.58 (<0.001)-0.18 (0.02)SOD (U/ml)0.48 (<0.001)NSGSH (U/ml)0.02 (0.75)NSHOMA-0.21 (0.001)NSeGFR (ml/min/ 1.73 m2)-0.03 (0.62)NShsCRP (mg/l)-0.45 (<0.001)NSPTX3 (ng/ml)-0.49 (<0.001)-0.21 (0.01)SBP (mmHg)-0.26 (<0.001)NSDBP (mmHg)-0.11 (0.12)NSHemoglobin (g/dl)0.07 (0.32)NSTotal Cholesterol (mg/dl)-0.05 (0.49)NSTriglyceride (mg/dl)-0.11 (0.12)NSLDL (mg/dl)-0.12 (0.07)NSHDL (mg/dl)0.02 (0.82)NSHbA1c (%)-0.26 (<0.001)NSFigure 1.Scatter-plot graphs between FMD and ADMA, MDA, CuZn-SOD, PTX-3.Conclusion:In our study we found sex differences regarding age and disease duration, being higher in women.

Network meta-analysis of His bundle, biventricular, or right ventricular pacing as a primary strategy for advanced atrioventricular conduction disease with normal or mildly reduced ejection fraction. J Cardiovasc Electrophysiol 2020; 31:1482-1492.

Abstract
INTRODUCTION Although right ventricular pacing (RVP) may impair ventricular function, it is commonly used for advanced atrioventricular block (AVB) and normal or mildly reduced ejection fraction (EF). We aimed to compare His bundle pacing (HBP), biventricular pacing (BiVP), and RVP for advanced AVB in patients with normal or mildly reduced EF. METHODS AND RESULTS MEDLINE, Embase, Cochrane CENTRAL, ClinicalTrials.gov, Scopus, and Web of Science were searched. Outcomes were all-cause death, heart failure hospitalizations (HFH), EF, left ventricular volumes, 6-minute walk test, and QRS duration. HBP or BiVP was compared with RVP. Subsequently, network meta-analysis compared the three pacing options. Our protocol was registered in PROSPERO (CRD42018094132). Six studies compared BiVP and RVP (704 vs 614 patients) and four compared HBP and RVP (463 vs 568 patients). Follow-up was 6 months to 5 years. There was significantly lower mortality and HFH with HBP or BiVP as compared with RVP (odds ratio [OR], 0.66, [0.51-0.85], P = .002; OR, 0.61 [0.45-0.82], P < .001, respectively]. HBP or BiVP also showed significant increase in EF and decrease in QRS duration (mean difference [MD], 5.27 [3.86-6.69], P < .001; MD -42.2 [-51.2 to -33.3], P < .001, respectively). In network meta-analysis, HBP and BiVP were associated with significantly improved survival compared to RVP, with surface under the cumulative ranking curve (SUCRA) probability of 79.4%, 69.4%, and 1.2% for HBP, BiVP, and RVP, respectively. For HFH, SUCRA probability was 91.5%, 57.2%, and 1.3%, respectively. CONCLUSION HBP or BiVP were the superior strategies to reduce all-cause death and HFH for advanced AVB with normal or mildly reduced EF, with no significant difference between BiVP and HBP.

Abstract
IntroductionPsychotherapy is one of the most widely investigated and practiced forms of treatment used in the treatment of different mental health problems. However, there are some barriers in delivering this treatment, including long waiting lists, therapist shortage and lack of access to therapists in remote areas. Therefore, using alternative methods to overcome these barriers seems necessary.MethodThe division of psychiatry at Queen's university provides different psychotherapy groups for individuals suffering from different kinds of mental health problem. We gave the participants the opportunity to choose online psychotherapy through an online clinic or the live group sessions. All the patients were assessed by different questionnaires for evaluation of the efficacy of the treatment. The online clinic was designed to facilitate the communication between patients and clinicians and the material was delivered in PowerPoint format through the online platform. All user activities were logged for security purposes.ResultsStatistical analysis showed that this method of delivering psychotherapy significantly reduced patients’ symptoms and also decreased the number of people on the waiting list and increased the amount of compliance in patient's taking part in psychotherapy and number of people who were able to receive psychotherapy.ConclusionDespite the proven short and long-term efficacy of psychotherapy, there are some barriers in delivering this treatment. It is an unequivocal public health needs to overcome these barriers through alternative methods of therapy. With Internet use ever rising, developing an online clinic could be a new way in delivering different kinds of psychotherapy.

Abstract
Patients with influenza infection are at increased risk of acute myocardial infarction (AMI). There are limited data on the short-term prognosis and management of patients with AMI and concomitant influenza. We examined the National Inpatient Sample from 2010 to 2014 for adult patients with a diagnosis of AMI. Patients were stratified into those with or without concomitant influenza. In-hospital therapies and outcomes were compared between groups in unadjusted and adjusted analyses. Standardized differences of >10% and p values <0.05 were considered significant. Propensity matching was performed using a caliper radius of 0.01*sigma. Of 4,285,641 patients with a discharge diagnosis of AMI, 12,830 had concomitant influenza. Patients with influenza were older, had a higher burden of co-morbidities, and more often presented with non-ST elevation AMI (90% vs 74%) as compared with those without influenza. Coronary angiography (23% vs 54%) and revascularization (11% vs 41%) were less often pursued in AMI patients with influenza. Patients with AMI and influenza had elevated in-hospital mortality (14%) and multiorgan failure (33%). In a propensity-matched analysis of 23,415 patients, in-hospital mortality (odds ratio [OR] 1.26; p = 0.01), acute kidney injury (OR 1.36; p <0.01), multiorgan failure (OR 1.81; p <0.01), length-of-stay, and hospital costs were significantly higher in those with influenza. In conclusion, patients with AMI and concomitant influenza have an adverse in-hospital prognosis as compared with those without influenza.

Abstract
In contrast with the conventionally observed mechanism of stochastic resonance (SR) wherein the level of additive noise is systematically varied with a fixed set-point parameter, in this work we report the emergence of the SR phenomena in an electrochemical system maintaining the same level of noise and varying the parametric distance from a homoclinic bifurcation inherent to the system. The experimental system involves the corrosion of a metal disk in an acidic medium under potentiostatic conditions. The applied potential is used as a control parameter and the anodic current generated during the electrodissolution of the metal is the accessible system variable. In the presence of noise, it was observed that the system was able to enhance its output's fidelity with a weak subthreshold input signal when the set point was kept at an optimal parametric distance from the bifurcation. Numerical simulations were performed on a model for this system to corroborate the experimental observations. This type of SR may be critical in scenarios where a biological entity has control only on its sensory parameters and not on the environmental noise amplitude.

Abstract
Abstract
Background
Medical therapy could improve the prognosis of real-life patients discharged after a heart failure (HF) hospitalization.
Purpose
We aimed to determine the impact of discharge HF treatment on mortality and readmissions in different left ventricular ejection fraction (LVEF) groups.
Methods
Multicentre prospective registry in 20 Spanish hospitals. Patients were enrolled after a HF hospitalization.
Results
A total of 1831 patients were included (583 [31.8%] HF with reduced ejection fraction [HFrEF]; 227 [12.4%] HF with midrange ejection fraction [HFmrEF]; 610 [33.3%] HF with preserved ejection fraction [HFpEF], and 411 [22.4%] with unknown LVEF. Angiotensin-converting enzyme (ACE) inhibitors/Angiotensin II receptor blockers (ARB) at discharge were independently associated with a reduction in: i) all-cause mortality: hazard ratio (HR) 0.55, 95% confidence interval (CI) 0.41–0.74, P<0.001, with a similar effect in the four groups; ii) mortality due to refractory HF HR 0.45, 95% CI 0.29–0.64, P<0.001, with a similar effect in the three groups with known LVEF; iii) mortality/HF admissions (HR 0.61; 95% CI: 0.50–0.74), more evident in HFrEF (HR 0.54; 95% CI: 0.38–0.78) compared to HRmEF (HR 0.64; 95% CI 0.40–1.02), orHFpEF (HR 0.70; 95% CI 0.53–0.92).Inpatients with HFrEFtriple therapy (ACE inhibitor/ARB+ betablocker+ mineralocorticoid receptor antagonist) was associated with the lowest mortality risk (HR 0.21; 95% CI: 0.08–0.57, P=0.002) compared to patients that received none of these drugs.

Abstract
Background and Purpose- The optimal antithrombotic strategy to balance thromboembolic and bleeding events, especially acute stroke, for patients with atrial fibrillation following coronary stenting remains a matter of debate. We conducted a network meta-analysis to identify the antithrombotic regimen associated with the lowest rate of bleeding and thromboembolic events in atrial fibrillation after coronary stenting. Methods- PubMed, Scopus, and Cochrane Central were searched for randomized controlled trials and observational studies of patients with atrial fibrillation after coronary stenting. The outcomes of interest were stroke, myocardial infarction, major adverse cardiac events, mortality, and major bleeding. A network meta-analysis was performed comparing the available antithrombotic regimens in the literature. Results- Three randomized and 15 observational studies were included, with a total of 23 478 participants. Median follow-up was 2 years. Network meta-analysis demonstrated that vitamin K antagonist plus single antiplatelet therapy or direct-acting oral anticoagulant plus single antiplatelet therapy were the most effective regimens in preventing stroke. Direct-acting oral anticoagulant regimens were associated with lower major bleeding rates than vitamin K antagonist regimens. Regimens with dual antiplatelet therapy were associated with lower rates of myocardial infarction. Vitamin K antagonist plus dual antiplatelet therapy was associated with a lower mortality and low-dose direct-acting oral anticoagulants with decreased major cardiovascular adverse events. Conclusions- Direct-acting oral anticoagulant regimens were associated with less major bleeding and major cardiovascular adverse events, but vitamin K antagonists were associated with decreased mortality and stroke. These results suggest that the decision of antithrombotic therapy in patients with atrial fibrillation after percutaneous coronary intervention needs to be individualized.

Abstract
We report experimental results indicating entrainment of aperiodic and periodic oscillatory dynamics in the Mercury Beating Heart (MBH) system under the influence of superimposed periodic forcing. Aperiodic oscillations in MBH were controlled to generate stable topological modes, namely, circle, ellipse, and triangle, evolving in a periodic fashion at different parameters of the forcing signal. These periodic dynamics show 1:1 entrainment for circular and elliptical modes, and additionally the controlled system exhibits 1:2 entrainment for elliptical and triangular modes at a different set of parameters. The external periodic forcing of the periodic MBH system reveals the existence of domains of entrainment (1:1, 1:2, 1:3, and 1:4) represented in the Arnold tongue structures. Moreover, Devil's staircase is obtained when the amplitude-frequency space of parameters of the applied signal is scanned.

Abstract
Background:
Coronary atherosclerosis is a dynamic disease with sudden and unpredictable bouts of progression. According to the most recent appropriateness use criteria (AUC), repeat testing within 2-years of a normal MPI is rarely appropriate for asymptomatic patients or in those with stable symptoms. Nonetheless, numerous patients with or without symptoms undergo repeat testing. Predictors of reversible ischemia on MPI within 2-years of a normal study has not been evaluated.
Methods:
After IRB approval, records from veterans who underwent multiple MPI stress testing within 2-years of a negative MPI, between 2013 and 2016, at our VA Medical Center were accessed and variables of interest collected. A multivariate logistic regression analysis was performed to determine predictors of reversible ischemia on repeat MPI.
Results:
We identified a total of 239 veterans with repeat stress MPI within 2-years of a prior negative MPI. The median age was 65, with 35% (83 of 239) having a history of clinical ASCVD. The median interval between tests was 14 months [IQR, 10 to 18]. Nearly 17% (41 of 239) of repeat tests were positive. Multivariate regression analysis failed to find an association between reversible ischemia on repeat MPI and our variables of interest as displayed in Table 1.
Conclusion:
Our study was unable to find a relationship between any traditional risk factors for ASCVD, including new symptoms, and the development of reversible perfusion defects on MPI within 2-years of a normal study. Further studies are needed to help identify those patients who would most benefit from a repeat MPI.

Abstract
BACKGROUND Management of chronic kidney disease (CKD) patients includes efforts directed toward modifying traditional cardiovascular risk factors. Such efforts include optimal management of hypertension together with the initiation of statin therapy. METHODS In this observational study, we determine the modifying effect of statins on the relationship of systolic blood pressure (SBP) goal with mortality and other outcomes in patients with CKD participating in a clinical trial. At baseline, 2,646 CKD patients (estimated glomerular filtration rate < 60 mL/min/1.73 m2) were randomized to an intensive SBP goal < 120 mm Hg or standard SBP goal <140 mm Hg. One thousand two hundred and seventy-three were not on statin, 1,354 were on a statin, and in 19 the use of statin was unknown. The 2 primary outcomes were all-cause mortality and cardiovascular disease (CVD) mortality. RESULTS The relationships of SBP goal with all-cause mortality (interaction p = 0.009) and cardiovascular (CV) mortality (interaction p = 0.021) were modified by the use of statin after adjusting for age, gender, race, CVD history, smoking, aspirin use, and blood pressure at baseline. In the statin group, targeting SBP to < 120 mm Hg compared to SBP < 140 mm Hg significantly reduced the risk of all-cause mortality (adjusted hazard ratio [aHR] 0.44 [0.28-0.71]; event rates 1.16 vs. 2.5 per 100 patient-years) and CV mortality (aHR 0.29 [0.12-0.74]; event rates 0.28 vs. 0.92 per 100 patient-years) after a median follow-up of 3.26 years. In the non-statin group, the risk of all-cause mortality (aHR 1.07 [0.69-1.66]; event rates 2.01 vs. 1.94 per 100 patient-years) and CV mortality (aHR 1.42 [0.56-3.59]; event rates 0.52 vs. 0.41 per 100 patient-years) were not significantly different in both SBP goal arms. CONCLUSION The combination of statin therapy and intensive SBP management leads to improved survival in hypertensive patients with CKD.

Abstract
OBJECTIVES To evaluate whether the levels of some molecules implicated in nucleocytoplasmic transport in human cardiomyocytes are related to the severity of heart failure (HF) in patients on the heart transplantation (HT) waiting list, and to determine whether there is a differential pattern of molecular alteration between ischemic cardiomyopathy (ICM) and non-ischemic dilated cardiomyopathy (DCM). METHODS Sixty-three blood samples collected before HT were analyzed to identify the levels of IMPORTIN5 (IMP5); IMPORTINalpha2; ATPaseCaTransp (ATPCa); NUCLEOPORIN153kDa (Nup153); NUCLEOPORIN160kDa (Nup160); RANGTPaseAP1 (RanGAP1) and EXPORTIN4 (EXP4). These data were then compared between patients with advanced HF with or without the need for ventricular support with extracorporeal membrane oxygenation (ECMO) as a bridge for HT, as well as between patients with non-ischemic DCM and patients with ICM. RESULTS Thirty-three patients had ICM, 26 had non-ischemic DCM, and 4 had heart disease. Seventeen patients required ventricular assistance as a bridge to HT. The levels of ATPCa, RanGAP1, and IMP5 were significantly higher in patients with ECMO, while EXP4 was significantly higher in patients without ECMO. Patients with DCM showed higher levels of IMP5, RanGAP1, and Nup153 than those with ICM. CONCLUSION Patients with advanced HF in critical condition (with ECMO as a bridge for HT) presented with significantly higher levels of ATPCa, RanGAP1, and IMP5, while patients with DCM had significantly higher levels of RanGAP1, IMP5, and Nup153. It remains to be clarified whether the determination of these molecules would facilitate the early identification of this group or if their alteration occurs as consequence of circulatory support with ECMO.
