Systemic thrombolysis in patients with acute stroke and active cancer: a systematic review and meta-analysis.

Cancer patients frequently have concomitant cerebrovascular diseases, which significantly worsen their prognosis. Prospective studies validating intravenous thrombolysis (IVT) safety profile in patients with acute ischemic stroke and active cancer are still lacking. Therefore, we aimed to evaluate IVT's efficacy and safety profile in acute ischemic stroke patients with comorbid active cancer.

Fetal brain biometry and cortical development in congenital heart disease: A prospective cross sectional study.

Objective: To evaluate brain biometry and cortical development by neurosonography in fetuses with congenital heart defect (CHD) and evaluate differences among different type of CHD.

Methods: In a prospective cross sectional study singleton fetus with CHD were matched with controls and grouped into two categories according to the predicted severity of cerebral arterial oxygen deficit induced by the CHD: Group A mildly reduced or normal and Group B moderately to severely reduced. Neurosonography was done at 30-33 weeks to obtain measurements of corpus callosum (CC), cerebellar vermis (CV), Sylvian fissure (SF) insula, parieto-occipital fissure (POF), and calcarine sulci fissures (CSF).

A novel experimental chamber for the characterization of free-falling particles in volcanic plumes.

Volcanic plumes pose a hazard to health and society and a particular risk for aviation. Hazard mitigation relies on forecasting plume dispersion within the atmosphere over time. The accuracy of forecasts depends on our understanding of particle dispersion and sedimentation processes, as well as on the accuracy of model input parameters, such as the initial particle size distribution and concentrations of volcanic particles (i.

The Hard Lessons Learned by the COVID-19 Epidemic in Italy: Rethinking the Role of the National Health Care Service?

The dramatic events precipitated by the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) virus pandemic have highlighted the limitations and contradictions of our country's current health care delivery model plagued by the closure of healthcare delivery structures, staff reductions, privatizations and inadequate funding which have been affecting the Italian National Health System during the past 10 years. The COVID-19 epidemic has a hefty bill: thousands of deaths - mainly elderly, hospitals overwhelmed, residential assistance structures reaching their limits, sick people left alone and uncared in homes, the disruption in life habits and an altered daily way of living never experienced before; all have contributed into making the ongoing tragedy even more painful. Herewith, we present and discuss the information and reflections from our experiences and postulate the rethinking of the established socio-health policies not only in Italy but also in other western countries which have failed to curtail the epidemic via conventional management approaches.

Clinical outcome with different doses of low-molecular-weight heparin in patients hospitalized for COVID-19.

A pro-thrombotic milieu and a higher risk of thrombotic events were observed in patients with CoronaVirus disease-19 (COVID-19). Accordingly, recent data suggested a beneficial role of low molecular weight heparin (LMWH), but the optimal dosage of this treatment is unknown. We evaluated the association between prophylactic vs.

Performance evaluation of hybrid crowdsensing systems with stateful CrowdSenSim 2.0 simulator.

Mobile crowdsensing (MCS) has become a popular paradigm for data collection in urban environments. In MCS systems, a crowd supplies sensing information for monitoring phenomena through mobile devices. Depending on the degree of involvement of users, MCS systems can be participatory, opportunistic or hybrid, which combines strengths of above approaches.

A novel experimental apparatus for investigating bubbly flows in a slot geometry.

Bubbly flows occur in a wide variety of industrial and environmental settings. While there is a broad literature that describes bubbly flow behavior in pipes and channels, flow in a high aspect ratio slot has received little attention. We describe the design and construction of a new experimental apparatus to investigate the processes associated with bubbly flows in a slot geometry.

The Impact of a New "Inverted Arch" Prosthetic Annuloplasty Ring on the Mitral Valve's 3-D Motion: An Experimental Ex-Vivo Study.

This experimental study aimed to evaluate the ex-vivo three-dimensional (3-D) motion of the Inverted Arch Ring (IAR), an innovative new design concept for a flexible incomplete annuloplasty prosthesis with an incorporated stabilizing rigid arch that can be used in correcting mitral valve regurgitation. Twenty explanted porcine hearts were placed in a circulation simulation system. Ultrasonometry transducers implanted in the mitral annulus were used to measure the 3-D valvular motion during a simulated cardiac cycle.

Acute decompensated heart failure in the emergency department: Identification of early predictors of outcome.

Identification of clinical factors that can predict mortality and hospital early readmission in acute decompensated heart failure (ADHF) patients can help emergency department (ED) physician optimize the care-path and resource utilization.We conducted a retrospective observational study of 530 ADHF patients evaluated in the ED of an Italian academic hospital in 2013.Median age was 82 years, females were 55%; 31.

5D CNS+ Software for Automatically Imaging Axial, Sagittal, and Coronal Planes of Normal and Abnormal Second-Trimester Fetal Brains.

The purpose of this study was to test new 5D CNS+ software (Samsung Medison Co, Ltd, Seoul, Korea), which is designed to image axial, sagittal, and coronal planes of the fetal brain from volumes obtained by 3-dimensional sonography. The study consisted of 2 different steps. First in a prospective study, 3-dimensional fetal brain volumes were acquired in 183 normal consecutive singleton pregnancies undergoing routine sonographic examinations at 18 to 24 weeks' gestation.

Immunomodulating treatment with low dose interleukin-4, interleukin-10 and interleukin-11 in psoriasis vulgaris.

Psoriasis is a chronic inflammatory skin disease affecting approximately 2-3 percent of the world population; it is characterised by hyperproliferation and hyperplasia of the superficial layers of the epidermis. Inappropriate signals released by the immune system determine an altered keratinocyte differentiation, resulting in the formation of desquamating, thickened, inflamed and erythematous plaques. The aim of this investigation was to study the pharmacological activity and safety of three low dose cytokines, Guna-Interleukin 4, Guna-Interleukin 10 and Guna-Interleukin 11 at the concentration of 10 fg/ml in patients affected by moderate to slight psoriasis vulgaris.

Uterine artery Doppler evaluation in twin pregnancies at 11 + 0 to 13 + 6 weeks of gestation.

Objectives: To compare uterine artery pulsatility index (PI) obtained at 11 + 0 to 13 + 6 weeks of gestation in singleton and twin pregnancies and to evaluate changes in PI values of twin pregnancies developing pre-eclampsia (PE) or small-for-gestational age (SGA) of either one or both fetuses.

Methods: Uterine artery PI was measured in 421 twin pregnancies (384 dichorionic and 37 monochorionic) and in 500 singleton pregnancies. The measured mean and lowest uterine artery PI values were converted to multiples of the expected normal median (MoM) after correction for maternal body mass index, ethnicity and gestational age.

Role of intramitochondrial arachidonic acid and acyl-CoA synthetase 4 in angiotensin II-regulated aldosterone synthesis in NCI-H295R adrenocortical cell line.

Although the role of arachidonic acid (AA) in angiotensin II (ANG II)- and potassium-stimulated steroid production in zona glomerulosa cells is well documented, the mechanism responsible for AA release is not fully described. In this study we evaluated the mechanism involved in the release of intramitochondrial AA and its role in the regulation of aldosterone synthesis by ANG II in glomerulosa cells. We show that ANG II and potassium induce the expression of acyl-coenzyme A (CoA) thioesterase 2 and acyl-CoA synthetase 4, two enzymes involved in intramitochondrial AA generation/export system well characterized in other steroidogenic systems.

First trimester placental volume and three dimensional power doppler ultrasonography in type I diabetic pregnancies.

Objective: This study aimed to investigate the placental volume and three dimensional (3D) power Doppler vascularization in type I diabetic pregnancies during the first trimester

Methods: 3D-power Doppler ultrasonography of the placenta was performed at 11+0-13+6 weeks in 32 pregnancies complicated by type I diabetes. Placental volume, vascularization index (VI), flow index (FI), and vascularization flow index (VFI) were calculated using a standardized setting.

Results: In nine pregnancies, a poor first trimester glycemic control was present as expressed by HbA1c levels  ≥ 7%, whereas in the remaining 23 mothers, the HbA1c concentrations were <7%.

Combined treatment with etanercept 50 mg once weekly and narrow-band ultraviolet B phototherapy in chronic plaque psoriasis.

The combination of etanercept, a tumour necrosis factor α inhibitor, with narrow-band ultraviolet B (NB-UVB) phototherapy has recently been reported to be effective in moderate-to-severe plaque psoriasis, yielding better results than either monotherapy. To assess the efficacy and safety of this combined treatment using the lower approved etanercept dosage. In this single-arm open-label study patients received etanercept 50 mg once weekly combined with NB-UVB phototherapy three times weekly for 8 weeks, followed by etanercept alone until week 12.

An algorithm based on OmniView technology to reconstruct sagittal and coronal planes of the fetal brain from volume datasets acquired by three-dimensional ultrasound.

Objective: To describe a novel algorithm, based on the new display technology 'OmniView', developed to visualize diagnostic sagittal and coronal planes of the fetal brain from volumes obtained by three-dimensional (3D) ultrasonography.

Methods: We developed an algorithm to image standard neurosonographic planes by drawing dissecting lines through the axial transventricular view of 3D volume datasets acquired transabdominally. The algorithm was tested on 106 normal fetuses at 18-24 weeks of gestation and the visualization rates of brain diagnostic planes were evaluated by two independent reviewers.
