The Diameter Distribution of the Stem Villi Arteries Does Not Discriminate between Normal and Intra Uterine Growth Restricted Placentas

The distribution of the stem villi arteries and arterioles diameter was evaluated on histological sections from 6 normal (control) and 8 Intrauterine Growth Restricted (IUGR) placentas. No significant difference between the diameter distributions was found. This result can be due either to a similar pattern in vascularization or to the inadequacy of the diameter distribution in showing existing differences. Further investigation is needed to make a distinction between these two hypotheses. A multiparametric model is proposed, which predicts the diameter distribution that is expected when a few parameters (describing the vessel geometry and the tree branching structure) are varied in their normal range. The diameter distribution is shown to slightly change or not to change at all when important parameters, such as the vessel asymmetry, are changed. We conclude thatthe diameter distribution is insensitive to variation in certain placental structural parameters. A reliable analysis of the stem villi vasculature in normal and TUGR placentas cannot be based on the comparison of the respective diameter distributions alone

Progressive fibrosing interstitial lung diseases: A current perspective

Interstitial lung diseases (ILDs) are a large and diverse group of rare and chronic respiratory disorders, with idiopathic pulmonary fibrosis (IPF) being the most common and best-studied member. Increasing interest in fibrosis as a therapeutic target and the appreciation that fibrotic mechanisms may be a treatable target of IPF prompted the development and subsequent approval of the antifibrotics, pirfenidone and nintedanib. The management of ILDs has changed considerably following an understanding that IPF and some ILDs share similar disease behavior of progressive fibrosis, termed “progressive fibrosing phenotype”. Indeed, antifibrotic treatment has shown to be beneficial in ILDs characterized by the progressive fibrosing phenotype. This narrative review summarizes current knowledge in the field of progressive fibrosing ILDs. Here, we discuss the clinical characteristics and pathogenesis of lung fibrosis and highlight relevant literature concerning the mechanisms underlying progressive fibrosing ILDs. We also summarize current diagnostic approaches and the available treatments of progressive fibrosing ILDs and address the optimization of treating progressive fibrosing ILDs with antifibrotics in clinical practice

Non-Invasive Estimation of Right Atrial Pressure Using a Semi-Automated Echocardiographic Tool for Inferior Vena Cava Edge-Tracking

The non-invasive estimation of right atrial pressure (RAP) would be a key advancement in several clinical scenarios, in which the knowledge of central venous filling pressure is vital for patients’ management. The echocardiographic estimation of RAP proposed by Guidelines, based on inferior vena cava (IVC) size and respirophasic collapsibility, is exposed to operator and patient dependent variability. We propose novel methods, based on semi-automated edge-tracking of IVC size and cardiac collapsibility (cardiac caval index—CCI), tested in a monocentric retrospective cohort of patients undergoing echocardiography and right heart catheterization (RHC) within 24 h in condition of clinical and therapeutic stability (170 patients, age 64 ± 14, male 45%, with pulmonary arterial hypertension, heart failure, valvular heart disease, dyspnea, or other pathologies). IVC size and CCI were integrated with other standard echocardiographic features, selected by backward feature selection and included in a linear model (LM) and a support vector machine (SVM), which were cross-validated. Three RAP classes (low 10 mmHg) were generated and RHC values used as comparator. LM and SVM showed a higher accuracy than Guidelines (63%, 71%, and 61% for LM, SVM, and Guidelines, respectively), promoting the integration of IVC and echocardiographic features for an improved non-invasive estimation of RAP

Fiber-reinforced lightweight foamed concrete panels suitable for 3D printing applications

This contribution presents a set of experimental results on fiber-reinforced innovative lightweight panels (FRIL-panels) having thickness of 12mm. These panels are prepared with a peculiar foamed concrete that has a high viscosity and cohesion in the fresh state, which makes it particularly suitable for 3D printing applications. The FRIL-panels can be used for internal partitions, external infills, and suspended ceilings of buildings as more effective solutions than conventional plasterboard ones, with better thermal insulation and acoustic absorption properties due to the internal air-void microstructure. The aim of this work is to investigate the out-of-plane resistance of FRIL-panels, prepared with a density of 800kg/m3, under displacement-controlled three-point bending tests. In view of potential use in the precast industry, the FRIL-panels were placed into an accelerated concrete curing tank so as to speed up the overall production process. Modulus of rupture, ultimate deflection and collapse mode of FRIL-panels are critically analysed and discussed

Valutazione Del Benessere Psico-Fisico Nell'aderenza Terapeutica Nelle Donne Con Malattia Renale Policistica Autosomica Dominante: Uno Studio Osservazionale

Evaluation Of The Psychophysical Well-Being In The Compliance Of Women With Autosomal Dominant Policystic Kidney Disease: An Observational Study BACKGROUND: Autosomal dominant polycystic kidney disease is the most common inherited renal disease and affects less than 1 every 400-1,000 people. There are many effective treatments, including blood pressure management, physical activity, low sodium diet and hydration. Therapeutic education is part of a patient's care and treatment. This approach is an essential strategy in order to face the current healthcare scenario, in which the number of people affected by chronic diseases is progressively increasing. OBJECTIVES: This article aims to analyze the effect of therapeutic education in patients with ADPKD, the level of adherence to pharmacological therapy and their compliance to dietetic and lifestyle recommendations as part of a nursing-led education. METHODS: This is a prospective, longitudinal, observational pilot study. The following measurements were used: Kidney Disease Quality of life - Short Form, Hospital Anxiety and Depression Scale, Body Uneasiness Test. At the T0 visit, a nurse selected patients and carried out a personalized educational intervention with the aims of adhering to drug therapies, monitoring blood pressure and dietary behavior (physical activity and water intake). At the T1 visit, patients performed psychological tests. At the T2 visit, the following evaluations were performed: a psychological interview together with the delivery and evaluation of the tests performed, an interview with the nurse to evaluate the adherence to the prescriptions, and a control of parameters such as physical activity, diet, water intake, drug therapy, and blood pressure. RESULTS: Therapeutic education can have a positive impact on patients' health by improving adherence to the pharmacological therapy, diet and lifestyle. CONCLUSIONS: Therapeutic education improve the patient's knowledge, treatments and correct behaviors as well as promotes an independent management of the disease. Through an educational intervention, the patient acquires the ability and the awareness to modify the wrong behaviors and to guarantee a balance between his needs and the pathology, thus improving the quality of life

Countering the Australian 'ndrangheta: The criminalisation of mafia behaviour in Australia between national and comparative criminal law

Mafia-type criminal groups belonging to, or originated from, the Calabrian ‘ndrangheta from Southern Italy, have been object of recent academic research and media attention in Australia. The Australian ‘ndrangheta, as qualified form of organised crime, poses new challenges for law enforcement in the country. This paper briefly looks at the strategies to fight organised crime in Australia, with specific focus on anti-association laws. By using a comparative approach, the paper will look at the criminalisation of mafias as qualified forms of organised crime in other two jurisdictions, Italy and the USA, to advocate for an effective mafia criminalisation in Australia. In conclusion, this paper will argue that, in order to also fight mafia phenomena, criminal law in Australia should focus on behaviours of organised crime groups rather than only on the criminalisation of proscribed associations and their illegal activities

Widening the Antimafia Net. Mafia Behaviour, Cultural Transmission and Children Protection in Calabrian mafia families

This article explores proceedings by the Youth Tribunal of Reggio Calabria, Southern Italy, aimed at the protection of children in families where one or both parents are investigated for mafia offences. The findings show that preventing the transmission of mafia (‘ndrangheta) culture in the local context has become an essential part of child protection measures. This article will argue that when discussing child protection in criminal families, it is necessary (a) to question the nature of the bonds of these families with the socio-cultural context, and (b) to concretely assess the way this context wishes to affect the family’s criminality
