A continuous-time Markov model approach for modeling myelodysplastic syndromes progression from cross-sectional data.

The integration of both genomics and clinical data to model disease progression is now possible, thanks to the increasing availability of molecular patients' profiles. This may lead to the definition of novel decision support tools, able to tailor therapeutic interventions on the basis of a "precise" patients' risk stratification, given their health status evolution. However, longitudinal analysis requires long-term data collection and curation, which can be time demanding, expensive and sometimes unfeasible.

Healthy Eating, Physical Activity, and Sleep Hygiene (HEPAS) as the Winning Triad for Sustaining Physical and Mental Health in Patients at Risk for or with Neuropsychiatric Disorders: Considerations for Clinical Practice.

Neuropsychiatric disorders stem from gene-environment interaction and their development can be, at least in some cases, prevented by the adoption of healthy and protective lifestyles. Once full blown, neuropsychiatric disorders are prevalent conditions that patients live with a great burden of disability. Indeed, the determinants that increase the affliction of neuropsychiatric disorders are various, with unhealthy lifestyles providing a significant contribution in the interplay between genetic, epigenetic, and environmental factors that ultimately represent the pathophysiological basis of these impairing conditions.

Laparoscopic Clipping of the Inferior Mesenteric Artery and Intraoperative Indocyanine Green Angiography for Type II Endoleak Following Endovascular Aneurysm Repair.

Type II endoleaks from a patent inferior mesenteric artery (IMA) occur in up to one-third of patients undergoing endovascular repair of abdominal aortic aneurysms. In the majority of patients, retrograde flow in the aneurysmal sac outside the endograft will seal over time and is rarely associated with sac enlargement or aortic rupture. Intervention is generally recommended in patients with progressively enlarging endoleaks, especially when the sac diameter increases >10 mm during the follow-up, and endovascular IMA embolization has a high rate of treatment failure.

Influence of the number of orientational domains on avalanche criticality in ferroelastic transitions.

We study the relationship between avalanche criticality and the number of orientational domains in ferroelastic transitions. To this end, we use a general Ginzburg-Landau model appropriate for displacive transitions of the square lattice. The model includes disorder as a quenched distribution of local transition temperatures.

Why Miss the Chance? Incidental Findings while Telescreening for Diabetic Retinopathy.

Purpose: To report on incidental pathological findings met while screening for Diabetic Retinopathy (DR) in Diabetes Clinics (DC) by ophthalmologist-graded digital fundus imaging.

Methods: At the DC of Pescara (central Italy), for 3,859 eyes of 1,930 consecutive patients having not undergone fundus examination in the last year, two mydriatic fundus digital images, taken with a CenterVue DRS Digital Retinal Camera, were sent along with Best Corrected Visual Acuity, on a "store-and-forward" basis, to an ophthalmologist trained in DR screening, and graded according to the UK Diabetic Eye Screening Programme. Incidental fundus abnormalities other than DR were reported.

Concentration-Dependent Effects of N-3 Long-Chain Fatty Acids on Na,K-ATPase Activity in Human Endothelial Cells.

N-3 eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) seem to prevent endothelial dysfunction, a crucial step in atherogenesis, by modulating the levels of vasoactive molecules and by influencing Na,K-ATPase activity of vascular myocytes. The activity of endothelial Na,K-ATPase controls the ionic homeostasis of the neighboring cells, as well as cell function. However, controversy exists with respect to the vascular protective effect of EPA and DHA.

Does variability in motor output at individual joints predict stride time variability in gait? Influences of age, sex, and plane of motion.

Old age is associated with variability in gait motor output, particularly in females, and is linked to fall risk. However, little is known about how older age and sex affect variability in the outputs of individual joints, and how these variabilities contribute to the collective gait output. Healthy adults aged 18-99 years (N = 102, 57 females) completed six trials of straight walking at self-selected speed.

Intravitreal anti-VEGF agents and cardiovascular risk.

Antagonists of Vascular Endothelial Growth Factor (Anti-VEGF) are widely administered by intravitreal injection for the treatment of ocular pathologies such as Age-related Macular Degeneration, Diabetic Macular Edema, Proliferative Diabetic Retinopathy and occlusion of retinal vessels. Anti-VEGF agents, in particular bevacizumab, were introduced in oncology to inhibit tumor-induced angiogenesis feeding neoplastic tissues. Subsequently, other specific agents were developed for intraocular administration.

Na/H exchanger isoform 1 activity in AQP2-expressing cells can be either proliferative or anti-proliferative depending on extracellular pH.

We have previously shown in renal cells that expression of the water channel Aquaporin-2 increases cell proliferation by a regulatory volume mechanism involving Na/H exchanger isoform 2. Here, we investigated if Aquaporin-2 (AQP2) also modulates Na/H exchanger isoform 1-dependent cell proliferation. We use two AQP2-expressing cortical collecting duct models: one constitutive (WT or AQP2-transfected RCCD cell line) and one inducible (control or vasopressin-induced mpkCCD cell line).

CD56 as a marker of an ILC1-like population with NK cell properties that is functionally impaired in AML.

An understanding of natural killer (NK) cell physiology in acute myeloid leukemia (AML) has led to the use of NK cell transfer in patients, demonstrating promising clinical results. However, AML is still characterized by a high relapse rate and poor overall survival. In addition to conventional NKs that can be considered the innate counterparts of CD8 T cells, another family of innate lymphocytes has been recently described with phenotypes and functions mirroring those of helper CD4 T cells.

Diabetic retinopathy, diabetic macular edema, and cardiovascular risk: the importance of a long-term perspective and a multidisciplinary approach to optimal intravitreal therapy.

Diabetic retinopathy (DR), diabetic macular edema (DME), and cardiovascular disease (CVD) resulting from vascular damage from persistently elevated blood glucose levels are among the serious secondary pathologies associated with long-standing diabetes mellitus. The established link between DR and CVD suggests the need for appropriate and early management of patients with diabetes to minimize CV risk. This is of particular importance in patients with recent, or a history of, major CV events.

Exploring circannual rhythms and chronotype effect in patients with Obsessive-Compulsive Tic Disorder (OCTD): A pilot study.

Background: The aim of this study was to test, through a chronobiologic approach, the existence of a significant circannual rhythm of tics and obsessive-compulsive symptoms in patients with Obsessive-Compulsive Tic Disorder (OCTD). The chronotype effect on tics and OC symptoms during seasons was also studied.

Methods: Patients with a diagnosis of OCTD (N = 37; mean age = 18.

Thiamine transporter 2 is involved in high glucose-induced damage and altered thiamine availability in cell models of diabetic retinopathy.

Thiamine prevents high glucose-induced damage in microvasculature, and progression of retinopathy and nephropathy in diabetic animals. Impaired thiamine availability causes renal damage in diabetic patients. Two single-nucleotide polymorphisms in locus encoding for thiamine transporter 2 are associated with absent/minimal diabetic retinopathy and nephropathy despite long-term type 1 diabetes.

Scientists' opinions and attitudes towards citizens' understanding of science and their role in public engagement activities.

The increasing perception that public communication in science and technology is an important tool to create a knowledge society is encouraging numerous public engagement activities. However, too little is known about scientists' opinions of and attitudes towards the public with whom they interact during these activities, especially in southern European countries such as Spain. If we want to establish an effective dialogue between science and society, we need to be aware of the opinions and perceptions that both parties have of each other.

Pretransplant active disease status and HLA class II mismatching are associated with increased incidence and severity of cytokine release syndrome after haploidentical transplantation with posttransplant cyclophosphamide.

Cytokine release syndrome (CRS) represents a life-threatening side effect after haploidentical stem cell transplantation (Haplo-SCT) with posttransplant cyclophosphamide (PT-Cy). Factors predictive of CRS development is still a matter of debate. We retrospectively analyzed 102 consecutive patients receiving a bone marrow (BM) (n = 42) or peripheral blood stem cells (PBSC) (n = 60) Haplo-SCT with PT-Cy.

Second primary malignancies in ruxolitinib-treated myelofibrosis: real-world evidence from 219 consecutive patients.

We present real-world data on all ruxolitinib-treated myelofibrosis patients in a 10-million-resident region, with a follow-up of 2 years. We found no evidence of an increased risk of developing lymphomas.

Is There Any Relationship between Upper and Lower Limb Impairments in People with Multiple Sclerosis? A Kinematic Quantitative Analysis.

Background: In people with multiple sclerosis (pwMS), disability is generally assessed on the basis of ambulation abilities, whereas upper limb motor dysfunctions are less frequently considered. Nevertheless, they can severely affect the quality of life of pwMS. To date, it remains mostly unknown whether a relationship exists between upper and lower limb impairments.

Age-Related Changes in Smoothness of Gait of Healthy Children and Early Adolescents.

In this study, we acquired and processed trunk accelerations during level walking in 85 children aged 8-13 years to calculate spatio-temporal parameters and Harmonic Ratio (HR), which is a metrics representative of gait smoothness and step-to-step symmetry. The results show that while spatio-temporal parameters remain unchanged once normalized considering individuals' anthropometry, significantly higher values of HR for both the antero-posterior and vertical directions were found in participants aged 12-13 with respect to those of 8-9. This indicates an improvement of gait symmetry, which suggests that the gait maturation process is still ongoing for the age ranges tested here.

Endoscopic submucosal dissection for superficial premalignant and malignant epithelial neoplasms of the digestive tract: a real-life experience in Italy.

Objective: Endoscopic submucosal dissection (ESD) is a technique for en bloc resection of neoplastic lesions of the digestive tract. Endoscopic submucosal dissection was developed in Asia, and data from Western countries are scarce. Our study aimed to assess the efficacy and safety of ESD for resection of superficial premalignant and malignant epithelial neoplasms in a tertiary center in Italy.

Age and growth of stocked juvenile Shoal Bass in a tailwater: Environmental variation and accuracy of daily age estimates.

Otolith microanalysis is often used to assess population age structure and growth of fishes during their early stages. Shoal Bass Micropterus cataractae is a recently described species of conservation concern and little is known regarding factors affecting their recruitment. In 2004, Georgia Department of Natural Resources (GADNR) and the US National Park Service (NPS) stocked Shoal Bass marked with oxytetracycline (OTC) in the Chattahoochee River near Atlanta, Georgia in an effort to restore this population, creating known-age fish to examine the effect of environment on daily age accuracy.

Vision-related quality of life and locus of control in type 1 diabetes: a multicenter observational study.

Aims: Diabetic retinopathy remains asymptomatic until its late stages but remains a leading cause of vision impairment and blindness. We studied quality of life and the ability to deal with the discomfort deriving from the presence of a chronic disease in patients with type 1 diabetes and different stages of retinopathy.

Methods: Multicenter collaborative observational study involving nine centers screening for retinopathy in different areas of Italy.

Improved Repeatability of the Estimation of Pulsatility of Inferior Vena Cava.

The inferior vena cava (IVC) shows variations of cross section over time (pulsatility) induced by different stimulations (e.g., breathing and heartbeats).

Sex-independent and dependent effects of older age on cycle-to-cycle variability of muscle activation during gait.

Background: Older age is associated with higher stride time variability in female and male gait, which may have a neuromuscular origin. We sought to determine how older age and sex affect muscle activation variability during gait, and how these patterns relate to stride time variability.

Methods: Ninety-three adults (51 females; aged 20-82 years) completed six gait trials at their self-selected speed.
