Abstract
BACKGROUND Kawasaki disease (KD) is a type of vasculitis in which giant coronary artery aneurysms (CAAs) can occur. There are no specific guidelines for managing giant CAAs that develop quickly and are at risk of rupture. Regarding cardiovascular drugs, only beta-blockers are formally recommended in the acute phase of KD. CASE PRESENTATION A 6-month-old male patient with multiresistant Kawasaki disease and giant CAAs that continued to enlarge after controlling systemic inflammation was examined. The patient required three doses of intravenous immunoglobulin, methylprednisolone pulses, and anakinra and infliximab to normalize systemic inflammation. Due to the rapid increment of aneurysms' dimensions and the risk of rupture, we introduced anticoagulant therapy and propranolol plus captopril, and titration doses were introduced according to a tolerated decrease in heart rate and arterial pressure. CAAs increment stabilized and slowly reduced their dimensions. CONCLUSIONS The authors describe an atypical case of multiresistant KD with giant rapidly increasing CAAs even after controlling systemic inflammation. The introduction of a beta-blocker and an angiotensin-converting enzyme (ACE) inhibitor was demonstrated to be useful for stabilizing giant CAAs growth and reducing the potential risk of rupture.

Assessing the Genotoxicity of Cellulose Nanomaterials in a Co-Culture of Human Lung Epithelial Cells and Monocyte-Derived Macrophages. Bioengineering (Basel) 2023; 10:986. [PMID: 37627871 PMCID: PMC10452089 DOI: 10.3390/bioengineering10080986] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Revised: 08/16/2023] [Accepted: 08/17/2023] [Indexed: 08/27/2023] Open
Abstract
Cellulose micro/nanomaterials (CMNMs) are innovative materials with a wide spectrum of industrial and biomedical applications. Although cellulose has been recognized as a safe material, the unique properties of its nanosized forms have raised concerns about their safety for human health. Genotoxicity is an endpoint that must be assessed to ensure that no carcinogenic risks are associated with exposure to nanomaterials. In this study, we evaluated the genotoxicity of two types of cellulose micro/nanofibrils (CMF and CNF) and one sample of cellulose nanocrystals (CNC), obtained from industrial bleached Eucalyptus globulus kraft pulp. For that, we exposed co-cultures of human alveolar epithelial A549 cells and THP-1 monocyte-derived macrophages to a concentration range of each CMNM and used the micronucleus (MN) and comet assays. Our results showed that only the lowest concentrations of the CMF sample were able to induce DNA strand breaks (FPG-comet assay). However, none of the three CMNMs produced significant chromosomal alterations (MN assay). These findings, together with results from previous in vitro studies using monocultures of A549 cells, indicate that the tested CNF and CNC are not genotoxic under the conditions tested, while the CMF display a low genotoxic potential.

Abstract
Abstract
Background
Despite recent advances, surgical aortic valve replacement (SAVR) remains the gold standard for most of the patients with aortic valve stenosis. The ageing population, with increased comorbidities and the rising of minimally invasive techniques, led to the development of new prosthetic devices of easier and faster implantation.
Purpose
This study aimed to analyse short and long-term outcomes of SAVR with rapid-deployment (RD) aortic bioprosthesis for isolated aortic valve stenosis
Method
Singe center, retrospective longitudinal cohort study of patients with isolated aortic valve stenosis who underwent elective aortic valve replacement using RD devices between 2014 and December 2021.
Continuous variables are presented with median (IQR) and were analyzed using Mann-Whitney test. Categorical variables are presented in percentage or frequency and were analyzed using chi-square test. Kaplan-Meyer survival curve was constructed base on collected data from national registry.
Results
A RD device was implanted in 358 patients with a median age of 75,8 years and Euroscore II of 2,3. Median cross clamp and extracorporeal circulation time were 27,4 and 36,7 min, respectively. No significant paravalvular leaks.
Intensive care unit (ICU) length of stay was 3 days with acute renal lesion (any stage-53,2%; Dialysis-2,5%), need for hemodynamic support (63,1%) and new onset atrial fibrillation (33,6%) being the most frequent post-operative complications. Stroke occurred in 0,6% of cases and mortality was 1,1%. Pacemaker implementation rate of 11%.
The mean follow-up time was 6,7 years with 90% 5-years survival rate. Mean gradients of 11,2±4,8 mmHg at 6 months
Conclusion
Surgical treatment of aortic valve stenosis using RD devices is safe, with a low mortality rate. ICU length of stay and hospital length of stay are reduced. Follow-up shows an excellent long-term survival and hemodynamic performance.

Adverse Outcome Pathways Associated with the Ingestion of Titanium Dioxide Nanoparticles-A Systematic Review. NANOMATERIALS (BASEL, SWITZERLAND) 2022; 12:nano12193275. [PMID: 36234403 PMCID: PMC9565478 DOI: 10.3390/nano12193275] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/17/2022] [Revised: 09/12/2022] [Accepted: 09/13/2022] [Indexed: 05/15/2023]
Abstract
Titanium dioxide nanoparticles (TiO2-NPs) are widely used, and humans are exposed through food (E171), cosmetics (e.g., toothpaste), and pharmaceuticals. The oral and gastrointestinal (GIT) tract are the first contact sites, but it may be systemically distributed. However, a robust adverse outcome pathway (AOP) has not been developed upon GIT exposure to TiO2-NPs. The aim of this review was to provide an integrative analysis of the published data on cellular and molecular mechanisms triggered after the ingestion of TiO2-NPs, proposing plausible AOPs that may drive policy decisions. A systematic review according to Prisma Methodology was performed in three databases of peer-reviewed literature: Pubmed, Scopus, and Web of Science. A total of 787 records were identified, screened in title/abstract, being 185 used for data extraction. The main endpoints identified were oxidative stress, cytotoxicity/apoptosis/cell death, inflammation, cellular and systemic uptake, genotoxicity, and carcinogenicity. From the results, AOPs were proposed where colorectal cancer, liver injury, reproductive toxicity, cardiac and kidney damage, as well as hematological effects stand out as possible adverse outcomes. The recent transgenerational studies also point to concerns with regard to population effects. Overall, the findings further support a limitation of the use of TiO2-NPs in food, announced by the European Food Safety Authority (EFSA).

Abstract
Funding Acknowledgements Type of funding sources: None. Background Cardiorespiratory fitness (CRF) is a powerful predictor of all-cause mortality among individuals with coronary artery disease (CAD). A structured community-based phase III cardiac rehabilitation (CR) is very important in lifelong maintenance of phase II CRF and health gains. During the COVID-19 pandemic, CR programs had to adapt, mainly using new technologies and remote follow-up. The CRF impact in patients (Ps) who kept going their phase III program, during this troubled era is still unknown. Purpose Assess the variation in CRF and prognostic parameters in Ps with CAD who maintain high adherence levels in their phase III CR before and during the COVID-19 pandemic. Methods A cohort of Ps enrolled in a community-based phase 3 CR program, with active participation at the end of 2019, was included in this retrospective study. The inclusion criteria for this study were high levels of attendance (>80%) to the CR program before and during COVID-19 and high levels of physical activity with more than 150 mins of moderate to vigorous physical activity (MVPA). All Ps were evaluated with transthoracic echocardiography (TTE) and a cardiorespiratory exercise test (CPET) in a cycloergometer in 2019 and between october and november of 2021. All Ps had used accelerometers to measure their physical activity levels and dual-energy absorptiometry (DEXA) scan to evaluate their body composition. Between 2020 and 2021, Ps had online (in lockdown periods) and face to face exercise training sessions, 3xtimes per week, 60 mins each exercise session. A t-test paired two sample for means was used to compare CPET variables before the beginning of the first COVID lockdown (end of 2019) and after the removal of the majority of restrictions (end of 2021). Results A total of 30 Ps with high levels of adherence were included (99.6% male, 65 ± 9 years old). In this cohort, the majority had history of an ACS before the referral to the CR program (73.3%) and 55.6 ± 10.4% of left ventricular ejection fraction. There was no significant difference in body mass index (27.9 ± 3.2 kg/m2 vs 28.1 ± 3.6 kg/m2, p=0.493 but there was a significant increase in the percentage of body fat mass (30.1 ± 5.7% vs 31.0 ± 6.6%, p= 0.042). There was a maintenance on MVPA levels (352 ± 137 minutes/week vs 313 ± 194 minutes/week, p = 0.106) during this period. When comparing the 2 CPET results, Ps achieved higher exercise loads in the 2021 test (175 ± 51W vs 185 ± 52W, p=0.005), higher VO2 peak (25.3 ± 6.9 ml/kg/min vs 21.5 ± 6.3 ml/kg/min, p =0.001) and higher percentage of predicted VO2max (78.8 ± 16.8% vs 95.27 ± 20.8%, p = 0.001). Conclusion In spite of all the difficulties in maintaining a phase III CR program during the COVID-19 pandemic, we observed that in physically active CAD Ps, with the aid of new technologies and remote follow-up (during the lockdown periods) and face to face exercise sessions, it is still possible to have functional gains and improvements in CRF.

Abstract
(1) Background: Nanocellulose is an innovative engineered nanomaterial with an enormous potential for use in a wide array of industrial and biomedical applications and with fast growing economic value. The expanding production of nanocellulose is leading to an increased human exposure, raising concerns about their potential health effects. This study was aimed at assessing the potential toxic and genotoxic effects of different nanocelluloses in two mammalian cell lines; (2) Methods: Two micro/nanocelluloses, produced with a TEMPO oxidation pre-treatment (CNFs) and an enzymatic pre-treatment (CMFs), and cellulose nanocrystals (CNCs) were tested in osteoblastic-like human cells (MG-63) and Chinese hamster lung fibroblasts (V79) using the MTT and clonogenic assays to analyse cytotoxicity, and the micronucleus assay to test genotoxicity; (3) Results: cytotoxicity was observed by the clonogenic assay in V79 cells, particularly for CNCs, but not by the MTT assay; CNF induced micronuclei in both cell lines and nucleoplasmic bridges in MG-63 cells; CMF and CNC induced micronuclei and nucleoplasmic bridges in MG-63 cells, but not in V79 cells; (4) Conclusions: All nanocelluloses revealed cytotoxicity and genotoxicity, although at different concentrations, that may be related to their physicochemical differences and availability for cell uptake, and to differences in the DNA damage response of the cell model.

Introduction
Transcatheter aortic valve implantation (TAVI) is currently the recommended treatment for aortic stenosis (AS) in high or intermediate-risk or inoperable patients. Balloon-expandable valve (BEV) and self-expanding valve (SEV) are the two major types of transcatheter heart valves (TTHV). Despite major diferences, both designs are recomended, however, there are only limited data available for the comparison of newer generation BEV and SEV.
Purpose
Compare echocardiographic and clinical parameters, during 1 year of follow-up of a balloon-expandable (BS) versus self-expanding (SE) transcatheter aortic valve implantantation, with emphasis on the composite endpoits proposed by uptade Valve Academic Researc Consortium (VARC-2).
Methods
Retrospective, comparative study in patients with symptomatic severe AS with a high operative risk, who implanted BEV or SEV between January 2016 and December 2019. All patients underwent echocardiographic study before an after the procedure (on the day , 6 months and 1 year of follow up), clinical data were collected. The following ecocardiographic parameters were evaluated: transvalvular and prosthetic aortic gradientes and paravalvular leak (PVL).
Results
We studied 106 patients (81 ± 8 years, 60% female) with severe AS (mean gradient of 49 ± 12 mmHg), who were threated with BE or SE transcatheter aortic valve. Comparative analysis between BEV vs SEV, showed: there were no statistically significant in mean transprosthetic gradients (9.5 ± 4.8 vs 10 ±6.2; p = 0.49). There were no statistically significant differences between BE and SE valves in the cumulative incidence of death from any cause (21% vs. 28%; p = 0.49), death from cardiovascular causes (3.3% vs. 0%; p= 0.26), all strokes (1.6% vs. 1.6%; p = 0.85), pacemaker implatation (18% vs. 15% p = 0.79); major bleeding (3.3% vs 6.5%; p = 0.18) and renal injury (1.6% vs. 2.1%: p = 0.67). There were statistically significant differences between BE and SE valves in the cumulative incidence of moderate or severe PVL (5% vs. 23.9%; p = 0.009) and repeat hospitalization (11.6% vs. 28%;p = 0.04). Device sucess was achieved in 97 % for BEV vs 91% for SEV (p = 0,39). The early safety at 30 days was observed in 5% for BVE vs. 4.3% for SVE (p = 0.87). The clinical efficacy after 30 days was achieved in 1,6% for BVE vs. 4.3% for SVE (p = 0.03), with higher incidence of moderate or severe PVL. The composite endpoint valve safety occured in 3,3 % for BVE vs 26% for SVE (p < 0,001), with moderate or severe PVL in 23%.
Conclusion(s): In patients with symptomatic severe aortic stenosis who implanted BEV or SEV transcatheter aortic valve there was a significant improvement in the hemodynamic status. The present study suggests that use of SEV was associated with a higher risk of PVL and repeat hospitalization, with a endpoint clinical efficacy after 30 days (4,3%) and time-related valve safety (26%).

Introduction
Regression of left ventricular mass (LVM) after transcatheter aortic valve implantation (TAVI) is an important parameter of left ventricular reverse remodeling and is associated with less hospitalizations 1year after TAVI. The association between LVM índex (LVMi) at 6 months and outcome 1 year after TAVI is unclear.
Purpose
Evaluate and compare LVMi, before TAVI and 6 months after, and determine the association between LVMi regression and clinical outcomes at 1-year follow-up.
Methods
Retrospective, comparative study in patients with symptomatic severe aortic stenosis with a high operative risk, after TAVI. All patients underwent echocardiographic study before TAVI and 6 months of follow-up, the LVMi (by the Devereux formula) was evaluated. Associations between LVMi regression (percent change between baseline and 6 months after TAVI), rehospitalization rate and death at 1 year of follow-up were examined.
Results
We studied 50 patients, 82% with moderade or severe LVMi before TAVI. Comparative analysis between ecocardiography study before and 6 months after TAVI, showed there was statistically significant decrease in LVMi (150,7 ± 38 g/m2 vs 132 ± 36 g/m2; p = 0.03). LVMi moderate or severe (between 130 and 154 g/m2) at 6 months was associated with biggest hospitalization rate (p = 0,03).Comparative analysis between regression of LVMi (before and 6 months after TAVI) and death, showed: decrease of 5% and 10% in LVMi was independently associated with death at 1 year (p = 0,77 vs p = 0,4).
Conclusions
Patients with severe symptomatic aortic stenosis treated with TAVI who had a significant decrease of LVMi after 6 months of follow-up had lower hospitalization rates, but decrease of LVMi is independently associated with death at 1 year of follow-up.

Abstract
Abstract
Introduction
Medical, surgical, and technological advances over the past decades increased the life expectancy of congenital heart disease (CHD) patients (pts), with >90% reaching adulthood. Nonetheless, mortality for adults with CHD (ACHD) is still higher than for the general population.
Purpose
To analyse trends in mortality and causes of death of ACHD.
Methods
Retrospective analysis of pts followed in an ACHD outpatient clinic, in one tertiary center, who died between 1980 and December 2020. Data relating to the cardiac diagnosis, symptoms, interventions, comorbidities, and causes of death were analysed.
Results
During a median follow-up of 8.9 years (IQR 2.2–17), 251 pts of 3725 (6.7%) died during the study period: 127 males (51%), mean age at death 44.9±18.1 years, 54% with severe CHD. The majority of these death was CHD-related (171 pts – 68.1%) with no statistically significant differences over the years vs non-cardiovascular death (Table 1). However, a paradigm shift was noticed: in the first years the main cardiac cause was sudden-death that was replaced by heart failure in the last decade. Also, the mean age at death increased over the years (33±14.9 years until 2000 vs 52.3±17 years after the year 2010, p<0.001) as the number of implantable devices (4 vs 20, p=0.05).
Conclusion
Causes of death of ACHD patients are in the majority still CHD-related. However, in the last decade, according to the increase in life expectancy, heart failure became the leading cause of death.

Abstract
Abstract
Introduction
Women with tetralogy of Fallot (TOF) have an increased risk of adverse cardiac and neonatal events during pregnancy. The aim was to assess fetal and maternal outcomes in patients (pts) with uncorrected and corrected TOF.
Methods
Retrospective analysis of cardiological and obstetric data in women with TOF followed at our institution. Pregnancy and neonatal outcomes were compared in patients (pts) submitted to corrective surgery vs pts with no previous intervention and in pts with or without cyanosis.
Results
51 women (median age 27 years; median number of previous interventions of 2), 22% with cyanosis, who experienced 126 pregnancies resulting in 73 live births A previous corrective surgery was found in 78% (40 pts), while 4% (2 pts) had previous palliative surgery and 18% (9 pts) no previous procedure. We found that women that were not submitted to previous intervention had a significant higher incidence of preterm birth (56% vs 17.5%, p=0.029), spontaneous abortion (56% vs 10%, p=0.006) and stillbirth (22% vs 0%). No difference was found for obstetric complications between groups. Cyanotic pts also demonstrated higher incidence of low birth weight (LBW) (36% vs 7.5%, p=0.031), preterm birth (54% vs 17.5%, p=0.021), spontaneous abortion (55% vs 10%, p=0.004) and stillbirth (18% vs 0%). There were no cardiac complications during pregnancy nor evident deterioration on cardiac status. Congenital heart disease was reported in 2 infants (3% of live births).
Conclusions
Pregnancy is well tolerated in pts with TOF. In our population, even in uncorrected TOF and in pts with cyanosis, there were no cardiac complications during pregnancy, although those pts had worse fetal outcomes. An explanation for the low incidence of cardiac events may be less severe forms of the disease, allowing survival into adulthood without intervention.

Abstract
Abstract
Background
Early diagnosis and prognostic stratification of hereditary transthyretin amyloidosis (ATTR) are crucial. Previous findings suggested that 99mTc-3,3-diphosphono-1,2-propanodicarboxylic acid (DPD) scintigraphy presents suboptimal accuracy to detect ATTR cardiomyopathy caused by V30M mutation, particularly in patients with onset of symptoms under 50 years of age. Furthermore, its prognostic value has never been evaluated in ATTR caused by this mutation.
Purpose
To assess the diagnostic value of DPD scintigraphy to detect cardiomyopathy in a large cohort of patients with ATTR-V30M mutation and to explore its prognostic value regarding mortality.
Methods
Of the 305 ATTR-V30M mutation carriers followed prospectively and who underwent DPD scintigraphy, 288 individuals [median age 46 (39–56); 49% male] without myocardial thickening attributable to other causes were enrolled in the study. Amyloid cardiomyopathy was defined by septal thickness ≥13mm not attributable to other causes plus at least one of the following criteria: (1) late heart-to-mediastinum (H/M) 123I-metaiodobenzylguanidine (MIBG) ratio <1.60; (2) electrical heart disease (arrhythmia or cardiac conduction defect); or (3) amyloid infiltration documented in biopsy.
Results
Amyloid cardiomyopathy was identified in 41 (14.2%) patients and 44 (15.3%) individuals presented abnormal cardiac DPD uptake. Individuals with cardiac DPD retention had 27-fold higher likelihood of having amyloid cardiomyopathy (OR: 27.4; 95% CI 11.6–65.0; P<0.001). However, DPD scintigraphy presented suboptimal accuracy to detect ATTR cardiomyopathy (89.9%) with limitations in sensitivity (56.1%), specificity (95.6%), positive predictive value (67.7%) and negative predictive value (92.9%).
During a mean follow-up 33.6±1.2 months, 16 patients died (5.6%). Mortality was 14 times higher in patients with amyloid cardiomyopathy (HR: 14.1; 95% CI 4.9–40.7; P<0.001), 13 times higher in those with abnormal cardiac DPD uptake (HR: 12.59; 95% CI % 4.56–34.72; P<0.001) and 10 times higher in those with H/M MIBG ratio <1.60 (HR: 10.40; 95% CI 2.95–36.69; P<0.001). The prognostic value of ventricular thickness and cardiac DPD uptake was additive: patients without septal thickening and no cardiac DPD retention had excellent prognosis (5-year mortality of 0.75%), while those with septal thickening and/or abnormal DPD retention presented 5-year mortality rates ranging from 39.9 to 53.3%.
Conclusions
DPD scintigraphy is valuable in the evaluation of ATTR-V30M mutation carriers, particularly for prognostic stratification purposes, identifying patients at higher risk of death.

Progress in pediatric cardiology and cardiac surgery has dramatically raised the number of women with severe complex congenital heart disease (SC-CHD) that reach reproductive age. Pregnancy (P) in this group of women has an increased risk of adverse cardiac and neonatal events and its predictive factors are not fully defined. Our purpose was to assess the experience of our center regarding P and neonatal outcomes in women with SC-CHD.
Methods
Retrospective analysis of obstetric data in women with CHD followed at our institution. P and neonatal outcomes were evaluated regarding patients presenting SC-CHD and mild and moderate complexity CHD (MMC-CHD), according to ESC guidelines CHD complexity classification.
Results
The study enrolled 680 women with CHD (median age, 27.2 years) who experienced 1262 pregnancies, resulting in 998 live births. A previous corrective procedure was found in 334 women (49.1%). CHD complexity was considered mild, moderate and severe in 263 (38.7%), 359 (52.8%) and 58 (8.5%), respectively. SC-CHD included 38 women with cyanotic CHD and 18 with pulmonary vascular disease. The most common heart defect in SC-CHD pts was cyanotic tetralogy of Fallot (19.0%), followed by dextro-transposition of the great arteries with atrial switch /palliative procedure (13.8%) – Figure 1.
Pts with SC-CHD had successful deliveries in 56.1% comparing with 82.1% in MMC-CHD. Women with SC-CHD had significantly higher incidence of preterm birth (24.6% vs 7.4%, p<0.001), spontaneous abortion (26.3% vs 12.3%, p=0.004) and neonatal mortality (10.3% vs 2.3%) comparing with MMC-CHD. Low birth weight was also extremely more frequent in the SC-CHD group (44.7% vs 8.5%, p<0.001). No difference was found relating to the presence of CHD in infants from SC-CHD mothers compared to off-spring from MMC-CHD (8.4 vs 5.3%, p=0.407). Cesarian deliveries had similar rates independently of increased CHD complexity (34.2% vs 32.1%). Overall, pregnancy was quite well tolerated, although cardiac complications were more common in SC-CHD P (0.4% vs 4.3%, p 0.013). Only one maternal death was registered, during 1st trimester, in a woman with a large unrepaired ventricular septal defect and cyanosis.
Conclusion
Severe complex CHD remains a challenging condition for pregnancy with increased maternal and neonatal morbimortality. This emphasizes the importance of extensive prepregnancy counselling and centralization of care to address specific risks and requirements of the condition.

Abstract
Introducción y objetivos Nuestro objetivo fue evaluar el impacto de la enfermedad del coronavirus de 2019 (COVID-19) en los ingresos en los servicios de urgencias (SU), las hospitalizaciones y el manejo clínico de los pacientes con urolitiasis. Pacientes y métodos Realizamos un análisis retrospectivo multicéntrico de las admisiones en los servicios de urgencias de tres departamentos de urología de gran volumen (uno directamente implicado en el tratamiento de los pacientes de COVID-19 y dos no implicados) en Roma (Italia) entre marzo y abril de 2020 y en el mismo período de 2019. Se realizó un análisis estadístico del número de admisiones por urolitiasis, la tasa de complicaciones, hospitalización y el tipo de tratamiento recibido. Resultados Fueron incluidos 304 pacientes en el análisis. Se observó una reducción significativa en el número global de pacientes ingresados en urgencias por urolitiasis entre 2019 y 2020 (48,8%). Además, con respecto a la elección del tratamiento de los pacientes hospitalizados, se informó un aumento estadísticamente significativo de los procedimientos de extracción de cálculos en comparación con el drenaje urinario en 2020 (p = 0,015). Conclusiones Durante la pandemia de la COVID-19 en Roma ha habido una reducción significativa de los ingresos en urgencias por urolitiasis. Los pacientes ingresados en el SU tuvieron más complicaciones, necesitaron hospitalización con más frecuencia y en cuanto al manejo clínico, se prefirió la extracción temprana de los cálculos, en vez del drenaje urinario. Todos los urólogos deben ser conscientes de que en los próximos meses podrían enfrentar un mayor número de admisiones por urolitiasis y un manejo de casos más complicados.

Abstract
Abstract
Background
Percutaneous Patent Foramen Ovale (pPFO) closure benefits for secondary prevention after cardio-embolic stroke have recently been proved. With the increasing number of cases and procedures, a concern with new onset atrial fibrillation (NOAF) has been raised.
Purpose
To evaluate long-term outcome regarding NOAF rate and to identify its predictors and clinical impact, in a real population submitted to pPFO closure.
Methods
From 2000 to 2017, consecutive patients (P) submitted to pPFO closure in a tertiary centre were prospectively enrolled. The primary endpoint was NOAF rate and secondary endpoints were all-cause, neurologic and cardiac mortality rates and recurrent ischemic events. Previous and follow-up electrocardiographic, echocardiographic and 24-hour heart rhythm monitoring data were analysed. Follow-up was performed through medical visits, medical charts consultation and a phone call based system, in order to assess clinical status, on-going treatment and events.
Results
496 patients were submitted to pPFO. Immediate success was achieved in 98.8% and 9.1% presented a residual shunt on the 1st year TEE. Mean age was 45.0±11.2 years-old with 50.2% of males. The prevalence of hypertension, hypercholesterolemia and atrial septum aneurysm (ASA) was 25.7%, 45.0% and 46.3%, respectively. Pre-procedural mean left atrial (LA) diameter was 36.0±5.3 mm. FU data was available for 490 (98.6%), for a mean FU time of 7.41±3.51 years. 34 P (6.9%) presented ischemic events recurrence (26 strokes and 8 TIA). The primary endpoint was observed in 21 P (4.3%) during the FU period.
Median time to 1st AF episode since PFO closure was 5.90±5.53 years. 11 P (52.3%) initiated oral anticoagulation. In univariate analysis, age (44.6±11.3 vs 51.8±6.0 years, p=0.005) and hypertension (24.7% vs 47.6%, p=0.019) were predictors of NOAF in this population. In multivariated analysis, only age remained a predictor of NOAF (OR 1.05 (1.007–1.101), p=0.025). LA pre pPFO closure dimensions, ASA, device type or size and the presence of residual shunt in TEE were not determinants of AF occurrence. The incidence of NOAF was associated with the need for hospitalization due to cardiac causes (19% vs 3.2%, p=0.001) and a trend towards higher rate of recurrent stroke (4.9% vs 14.3%, p=0.06).
Conclusion
Despite being a highly successful and safe procedure in most patients, pPFO closure was associated with a non-negligenciable rate of NOAF during long-term follow-up. NOAF predictors were related with classical cardiovascular risk factors, such as age and hypertension. None of the procedure or device features were associated with NOAF. Yet, a clinical impact was attributed to NOAF, with more hospitalizations and a trend towards ischemic events recurrence.
As young patients submitted to pPFO closure grow older, prevention strategies to diagnose and treat NOAF should be endeavoured.

Introduction
Cardiac sympathetic activation and inflammatory response are involved in chronic heart failure (HF) pathophysiology. The severity of autonomic dysfunction and inflammation might be responsible for different responses to HF treatment.
Aim
To evaluate the impact of cardiac autonomic dysfunction, and it´s association with systemic inflammation, on cardiac resynchronization therapy (CRT) response in severe HF patients.
Methods
Single centre, prospective, longitudinal study, including consecutive patients, referred to CRT. Demographic data, HF aetiology and NYHA class were evaluated. Left ventricular (LV) function data (LV ejection fraction - LVEF) by echocardiography, heart to mediastinum early ratio (HMRe) by 123I-MIBG cardiac scintigraphy, and plasmatic TNF-α levels (pg/mL) were determined, at baseline and 4 months after CRT implantation. CRT response was defined by an absolute increase of at least 5% in LVEF at 4 months evaluation after CRT. Patients were divided in 4 groups according to HMRe and TNF-α cut-points: Group I (TNF-α > 2.0 pg/ml + HMRe ≥ 1.6), Group II (TNF-α > 2.0 pg/ml + HMRe < 1.6), Group III (TNF-α ≤ 2.0 pg/ml + HMRe ≥ 1.6) and Group IV (TNF-α ≤ 2.0 pg/ml + HMRe < 1.6). Data was analyzed using descriptive statistics and groups were compared by Fisher"s exact test.
Results
A total of 95 patients were included (age 68.6 ± 10.2 years), 67.4% male and 32.6% female, 40% with diabetes mellitus, 30.5% with ischemic cardiomyopathy, 23.2% in NYHA III/IV, baseline LVEF - 26 ± 7%. At 4 months, LVEF was 40 ± 11%. In total, 73.7% were responders and 26.3% were non-responders to CRT. There were 28 patients (29.5%) with HMRe ≥ 1.6, with 25 responders (89.3%) and 48 patients (50.5%) with TNF-α ≤ 2.0 pg/ml, with 38 responders (79.2%). Group I had 16 patients (16.8%), with 81.2% responders; Group II had 31 patients (32.7%), with 61.3% responders; Group III had 12 patients (12.6%), with 100% responders, and Group IV had 36 patients (37.9%), with 72.2% responders. Conclusion: In patients with severe HF submitted to CRT, combining cardiac autonomic dysfunction and inflammation, associated to high rate of CRT non response. Contrarily, those with preserved cardiac autonomic function and no increased levels of inflammation identified most significantly CRT responders.

Abstract
Abstract
Introduction
Pulmonary vein isolation (PVI) is the central element in the ablation of atrial fibrillation (AF), and can be obtained with different ablation modalities. The duty-cycled circular multi-pole catheter PVAC® (Medtronic) allows linear application of radiofrequency energy, with the production of circumferential lesions. Conceptually, it can make ablation simpler and faster in patients with favorable anatomy.
Objectives
To evaluate the safety and efficacy of ablation with a PVAC® catheter and to compare it with the conventional technique point-by-point (PbP) with irrigated catheter.
Methods
Clinical trial with single-blinded patients with AF refractory to antiarrhythmic therapy, randomized (1: 1) for ablation with PVAC® or PbP. The ablation strategy consisted of PVI, complemented with ablation of the cavo-tricuspid isthmus in patients with history of concomitant flutter. Monitoring was performed with a 7-day event loop recorder at 3, 6 and 12 months and annually from the 2nd year. Success was defined by AF-free survival or any maintained supraventricular tachycardia (duration > 30seconds).
Results
354 patients (67.5% males, 58 ± 12 years, PbP: 175, PVAC: 179) were included, of which 59.1% had paroxysmal, 26.2% short-standing persistent and 14.7% had long-standing persistent AF. Baseline characteristics were similar between groups. Among patients treated with PVAC, 93.1% of the pulmonary veins were isolated (620/666), similar to the 98.3% immediate success of the PbP group (697/709). Although the complication rate was similar in both groups (PVAC: 4.9% vs. PbP: 7.8%; P = NS), the risk of hemopericardium was lower with PVAC (0% vs. 4.6%; P = 0.013). Two patients treated with PVAC developed stroke (1.13% vs. 0%; P = NS). The duration of the procedure was lower among the patients treated with PVAC [136 (100-180) vs. 230 (188-270) min; P <0.001], with no difference in fluoroscopy time [24.4 (14.5-36.8) vs. 27.1 (17.0-45.0) min]. The success rate after 1st ablation at 36 months was 68%, with no differences between groups. The success rate after multiple ablations increased to 85.8%, with no differences between groups.
Conclusion
The multipolar PVAC catheter can represent an added value in AF ablation, making the procedure simpler and faster, ensuring similar efficacy to the conventional technique and with a lower risk of cardiac tamponade. The present trial suggests the need for clinically manifested stroke risk surveillance, which may be increased with this technique.

Abstract
OBJECTIVE Sudden cardiac death is common in the adult congenital heart disease (ACHD) population. Knowledge and experience about the use of implantable cardioverter defibrillators (ICD) in ACHD patients is very limited. We aimed to characterize a cohort of patients with ACHD and ICDs. DESIGN Thirty consecutive ACHD patients submitted to an ICD implantation in a single tertiary center were evaluated. Data on baseline clinical features, heart defect, indication for ICD, type of device, appropriate therapies, ICD-related complication, and mortality during follow-up were collected. RESULTS Of the 30 patients, 56.7% received appropriate therapies due to ventricular tachycardia (VT) or ventricular fibrillation (VF). The rate of inappropriate therapies and device-related complications was 33.3%. Secondary prevention and primary prevention patients with class I indications for ICD had more appropriate therapies than complication, but this relationship was reversed for patients with class II indications. Remote monitoring played an important role in diagnosing new atrial arrhythmias before scheduled visits in 46.2% of patients, leading to a change in medication. VT/VF episodes were associated with a composite of death, cardiac transplantation, and hospital admission (OR 13.0; 95% CI: 2.1-81.5). CONCLUSION ICDs are not only useful in preventing SCD, but also have a major role in diagnosing atrial tachyarrhythmias ahead of scheduled visits. Although improvements in ICD technology might reduce complications and inappropriate therapies, adequate selection of candidates for primary prevention still remains difficult because of the lack of clear indications.

Abstract
Blends of rice waste streams were submitted to co-gasification assays. The resulting chars (G1C and G2C) were characterized and used in Cr(III) removal assays from a synthetic solution. A Commercial Activated Carbon (CAC) was used for comparison purposes. The chars were non-porous materials mainly composed by ashes (68.3-92.6% w/w). The influences of adsorbent loading (solid/liquid ratio - S/L) and initial pH in Cr(III) removal were tested. G2C at a S/L of 5 mg L-1 and an initial pH of 4.50 presented an uptake capacity significantly higher than CAC (7.29 and 2.59 mg g-1, respectively). G2C was used in Cr(III) removal assays from an industrial wastewater with Cr(III) concentrations of 50, 100 and 200 mg L-1. Cr(III) removal by precipitation (uptake capacity ranging from 11.1 to 14.9 mg g-1) was more effective in G2C, while adsorption (uptake capacity of 16.1 mg g-1) was the main removal mechanism in CAC.

Abstract
INTRODUCTION The present work presents data on research into adolescents who committed sex offenses, carried out in the Apulia Region of southern Italy and focused in particular on the perpetrators' perception of the peculiar profile of the criminal act committed. MATERIALS AND METHODS Three University sections of the School of Medicine, Bari University, took part in this research: Criminology and Forensic Psychopathology, Psychiatry and Juvenile Neuropsichiatry, working in collaboration with the Department for Juvenile Justice and the Community, and the Center for Juvenile Justice in Apulia. In total, 31 subjects were included in the study, all Juvenile Sex Offenders. A detailed questionnaire was employed to obtain all the relevant information of criminological concern. DISCUSSION Among most of the minors considered, a very poor awareness emerged of the peculiar type of offense committed, and of its consequences on the victims and the social context. RESULTS This finding highlights an evident contradiction and confusion between legislative provisions in the area of sex offenses and rape, and the perspectives of juveniles and adolescents. CONSLUSIONS There is an evident need for legislative norms to adopt registers that are more accessible to the complex juvenile world, that cannot be assimilated to the adult world.

Abstract
The T-box transcription factor Brachyury has been considered a cancer-specific marker and a novel oncotarget in solid tumors. Brachyury overexpression has been described in various cancers, being associated with epithelial-mesenchymal transition, metastasis, and poor prognosis. However, its clinical association with testicular germ cell tumor is unknown. We analyzed the expression of Brachyury by immunohistochemistry in a series of well-characterized testicular germ cell tumor samples and at transcript level by in silico analysis. Additionally, we aimed to investigate the clinical significance of Brachyury in testicular germ cell tumor. Brachyury cytoplasm immunostaining was present in 89.6% (86/96) of cases with nuclear staining observed in 24% (23/96) of testicular germ cell tumor. Bioinformatics microarray expression analysis of two independent cohorts of testicular germ cell tumors showed similar results with increased levels of Brachyury in testicular germ cell tumors and metastasis compared with normal testis. Clinically, Brachyury nuclear staining was statistically associated with lower event-free survival (p = 0.04) and overall survival (p = 0.01) in intermediate/high-risk testicular germ cell tumors. Univariate analysis showed that Brachyury nuclear subcellular localization was a predictor of poor prognosis (p = 0.02), while a tendency was observed by multivariate analysis (HR: 3.56, p = 0.06). In conclusion, these results indicate that Brachyury plays an oncogenic role in testicular germ cell tumors and its subcellular localization in the nucleus may constitute a novel biomarker of poor prognosis and a putative oncotarget for intermediate/high-risk testicular germ cell tumor patients.

Abstract
Background Overactive bladder is a high prevalent and quality of life affecting disease. The mainstay of the medical therapy is represented by antimuscarinic drugs, but their side effects markedly affect patient compliance and prompt studies on novel investigational drugs. Methods A systematic literature search of peer-reviewed papers and meeting abstracts published by December 2008 was performed. PubMed databank was searched for original English articles, by using the following search terms: “overactive bladder” or “detrusor overactivity” or “urinary incontinence” and “treatment”, alone and linked to any potential molecular target or novel drug cited in the literature. Results Effective alternative pharmacological treatments are currently scarce, but many new promising compounds are emerging which target key molecular pathways involved in micturition control. The most promising potential therapeutic targets include central nervous system GABAergic inhibitory pathway, dopaminergic and serotoninergic systems, b-adrenoceptors and cAMP metabolism, nonadrenergic-noncholinergic mechanisms such as purinergic and neuropeptidergic systems, vanilloid receptor, bladder sensory nervous terminals, nonneuronal bladder signalling systems including urothelium and interstitial cells, prostanoids, Rho-kinase and different subtypes of potassium and calcium channels. Conclusions Despite the enormous amount of new biologic insight, very few novel pharmacological therapies seems to have passed the proof-of-concept clinical stage. The ultimate clinical utility of new drugs will depend on the ability to exploit tissue-specific differences and disease-related changes in molecular expression/function and to improve storage phase dysfunctions without interfering with the emptying phase. Further preclinical investigations and controlled clinical trials are urgently needed in this challenging field.

Abstract
In the last decades a growing interest has been dedicated to prevention, diagnosis and therapy of male genital pathologies, such as varicocele, infertility and erectile dysfunction in the population involved in sport activities. High incidence (up to 30%) of varicocele has been reported in a population of athletes and up to 60–80% in the subgroup of body-builders. The incidence of varicocele specifically increases with hours of training, in a linear model. Controversial data come from literature about the effects of physical activity on fertility, with prevalence of trials demonstrating worsening of seminal parameters. Furthermore, it has been demonstrated that physical stress in healthy male athletes can interfere with LH levels. Bicycling is one of the major risk factors for erectile dysfunction, with incidence of 13–24%. This is due to the prolonged compression of perineal arteries leading to reduced chronic penile perfusion. Bioengineering studies have been the basis for industry to produce specifically shaped saddles that significantly reduce and minimize compressive effects. Finally, high frequency of lower urinary tract symptoms (LUTS) in cyclists has been related to increased incidence of erectile dysfunction in comparison with normal population.

Abstract
Introduction Statistical data referring to sports-related traumas of the urinary tract are quite scarce; nevertheless, it is possible to draw general data on the relationship between sports and urological traumas. Methods Literature review of peer-reviewed articles published by May 2009. Results Urological traumas account for about 10% of all traumas, and about 13% of them is sports-related. Genitourinary traumas are among the most common cause of abdominal injuries in sports. Blunt injuries are more common than penetrating ones and renal injuries are by far the most common, followed by testicular injuries; ureters, bladder and penis injuries are much more infrequent. Considering chronic microtraumas, injuries of bulbar urethra are also common in sports that involve riding. Overall, the incidence of genitourinary trauma due to sports is low. Renal traumas in sports injuries usually consist of grade 1–11 lesions and usually do not require surgical treatment. Cycling is the sporting activity most commonly associated with genitourinary injuries, followed by winter sports, horse riding and contact/collision sports. Literature data suggest that significant injuries are rare also in athletes with only one testicle or kidney. General preventive measures against sport-related injuries, along with the use of protective cups for male external genitalia, are generally sufficient to reduce the incidence of urogenital trauma. Conclusions Overall, studies show that urogenital injuries are uncommon in team and individual sports, and that most of them are low-grade injuries. Participation in sports that involve the potential for contact or collision needs to be carefully assessed in the athletes with only one testicle or kidney, even though urogenital injuries should not preclude sports participation to an appropriately informed and counseled patient. Further research is needed to acquire more knowledge on genitourinary injuries according to age, sports type and technical skill.

Abstract
Clinical effectiveness of botulinum toxin (BTX) in the treatment of both neurogenic and idiopathic detrusor overactivity has been demonstrated in several studies. However, different protocols and techniques have been used by authors. Methods. Literature review on intradetrusor injection of BTX for detrusor overactivity. Results. The greatest clinical experience reports the use of 200 and 300 U Botox®. Available data suggest that clinical efficacy, duration, and the side effect profile is similar at these doses. Very few data, on the other hand, are available regarding the clinical outcomes using the Dysport® preparation; isolated reports support that efficacy is similar when using a dosing range of 500 to 1000 SU with increased risk of systemic side effects using 1000 SU. A variety of injection volumes was used, demonstrating similar efficacy and tolerability profile. Clinical effect duration extends six to ten months in the majority of studies. Data suggest that a repeated injection scheme proves successful in the vast majority of initial responders. Conclusions. Safety, effectiveness, specificity and reversibility make BTX a new attractive treatment modality for overactive bladder syndrome. However, more experience is needed to standardize the injection protocol with respect to therapeutic outcomes and adverse effects.

Abstract
Introduction Prostatitis-like syndromes are high prevalent health problems and frequently considered by patients and physicians as strictly correlated to sports causing perineal compression. These syndromes and their relationships with sporting activities have been discussed in this report. Methods We reviewed peer-reviewed scientific articles published by May 2009 and searched according to the following term selection: prostatitis, pudendal nerve, sport, cycling. Results Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a major healthcare burden heavily affecting patients’ Quality of Life. No clear evidence of any direct etiologic relationship has been found in literature between prostatitis, either bacterial or non-bacterial, and sports activities. On the other hand, some types of sport causing perineal compression, such as cycling, can exacerbate symptoms of acute and chronic prostatitis; a temporary sport discontinuation is justified in these patients. CP/CPPS may be often caused by pudendal nerve entrapment (PNE). Prostatitis-like urogenital neuropathic pain together with voiding and sexual dysfunctions are the hallmark of PNE. A common feature is that flexion activities of the hip, such as climbing, squatting, cycling provoke or worsen urogenital pain or pelvic pain. Many of the patients with PNE are cyclists, played American football, lifted weights, or wrestled as teenagers and young adults. PNE represents the most common bicycling associated urogenital problems. Conclusions Overall, studies show that no causal relationship has been demonstrated between prostatitis and sporting activities. Conversely, urologists should be aware that sports involving vigorous hip flexion activities or prolonged perineal compression are a potential and not an infrequent cause of uroand rological symptoms caused by pudendal nerve entrapment.

Abstract
Bladder cancer is among the top eight most frequent cancers. Its natural history is related to a combination of factors that impact on its aggressiveness. Cystoscopy and urine cytology are the currently used techniques for the diagnosis and surveillance of non-invasive bladder tumors. The sensitivity of urine cytology for diagnosis is not high, particularly in low-grade tumors. The combination of voided urine cytology and new diagnostic urine tests would be ideal for the diagnosis and follow-up of bladder cancer. However, in order to have some clinical utility, new diagnostic and/or prognostic markers should achieve better predictive capacity that the currently used diagnostic tools. None of the markers evaluated over the last years showed remarkable sensitivity or specificity for the identification of any of the diverse types of bladder cancer in clinical practice. The limitations of the known prognostic markers have led to the research of new molecular markers for early detection of bladder cancer. This research focused in particular on the discovery of biomarkers capable of reducing the need for periodic cystoscopies or, ideally, offering a non-invasive examination instead. In this review, we will examine various new markers of bladder cancer and their value in the diagnosis and follow-up of non-muscle-invasive bladder cancer. When compared with urine cytology, which showed the highest specificity, most of these markers demonstrated an increased sensitivity.

Abstract
Aorto-left ventricular tunnel is a rare congenital cardiac anomaly, consisting of a short abnormal pathway, usually from a sinus of Valsalva into the left ventricular cavity. It is usually diagnosed with echocardiography. We report a case of a newborn presenting with heart murmur and rapid progression to heart failure and left ventricular enlargement due to an aorto-left ventricular tunnel. Despite successful closure of the tunnel, the patient required a Ross procedure due to progressive aortic disease.

Properties of chars from the gasification and pyrolysis of rice waste streams towards their valorisation as adsorbent materials. WASTE MANAGEMENT (NEW YORK, N.Y.) 2017; 65:186-194. [PMID: 28400156 DOI: 10.1016/j.wasman.2017.04.011] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/29/2017] [Revised: 03/21/2017] [Accepted: 04/03/2017] [Indexed: 06/07/2023]
Abstract
Rice straw (RS), rice husk (RH) and polyethylene (PE) were blended and submitted to gasification and pyrolysis processes. The chars obtained were submitted to textural, chemical, and ecotoxic characterisations, towards their possible valorisation. Gasification chars were mainly composed of ashes (73.4-89.8wt%), while pyrolysis chars were mainly composed of carbon (53.0-57.6wt%). Silicon (Si) was the major mineral element in all chars followed by alkaline and alkaline-earth metal species (AAEMs). In the pyrolysis chars, titanium (Ti) was also a major element, as the feedstock blends contained high fractions of PE which was the main source of Ti. Gasification chars showed higher surface areas (26.9-62.9m2g-1) and some microporosity, attributed to porous silica. On the contrary, pyrolysis chars did not present a porous matrix, mainly due to their high volatile matter content. The gasification bed char produced with 100% RH, at 850°C, with O2 as gasification agent, was selected for further characterization. This char presented the higher potential to be valorised as adsorbent material (higher surface area, higher content of metal cations with exchangeable capacity, and lowest concentrations of toxic heavy metals). The char was submitted to an aqueous leaching test to assess the mobility of chemical species and the ecotoxic level for V. fischeri. It was observed that metallic elements were significantly retained in the char, which was attributed mainly to its alkaline character. This alkaline condition promoted some ecotoxicity level on the char eluate that was eliminated after the pH correction.
