Dietary Habits, Physical Activity and Body Mass Index in Transgender and Gender Diverse Adults in Italy: A Voluntary Sampling Observational Study.

Transgender and gender-diverse (TGD) individuals continue to experience harassment and discrimination across various aspects of life, significantly impacting their physical and mental health. The scarcity of data on their general health, particularly regarding dietary habits, remains a challenge in developing effective healthcare strategies for this population. To address this gap, we analyzed selected dietary habits, physical activity (PA), and body mass index (BMI) among Italian TGD adults compared to the Italian general population (IGP). An online anonymous survey was conducted via the Computer Assisted Web Interviewing technique from June 2020 to June 2021. Participants were enrolled through clinical centers and TGD organizations. Data from 959 TGD adults were analyzed using chi-squared tests and logistic regression models. Key findings indicated that approximately 70% of TGD individuals consumed fewer servings of fruit and vegetables (FV) than recommended (five or more servings per day). Although red meat consumption was lower overall, a greater percentage of TGD individuals reported consuming more than three servings per week. Additionally, 58% of TGD participants indicated that they did not engage in any PA, compared to 36% of the IGP. Notably, significant differences in BMI were identified, with higher rates of overweight and obesity among TGD individuals assigned female at birth. These results underscore the urgent need for tailored nutritional guidelines and inclusive public health strategies to meet the specific health needs of the Italian TGD population. Expanding access to targeted interventions could contribute to improving overall well-being in this marginalized group.

Fractional-order poromechanics for a fully saturated biological tissue: Biomechanics of meniscus.

Biomechanics of biological fibrous tissues as the meniscus are strongly influenced by past histories of strains involving the so-called material hereditariness. In this paper, a three-axial model of linear hereditariness that makes use of fractional-order calculus is used to describe the constitutive behavior of the tissue. Fluid flow across meniscus' pores is modeled in this paper with Darcy relation yielding a novel model of fractional-order poromechanics, describing the evolution of the diffusion phenomenon in the meniscus. A numerical application involving an 1D confined compression test is reported to show the effect of the material hereditariness on the pressure drop evolution.

Carotid Artery Disease in the Era of Biomarkers: A Pilot Study.

The intima-media thickness (IMT) and its irregularities or ulcerations in the common carotid artery (CCA) are useful tools as sentinel biomarkers for the integrity of the cardiovascular system. Total homocysteine and lipoprotein levels are the most commonly used elements in cardiovascular risk stratification. Duplex ultrasound (DUS), associated with serum biomarkers, can be used simply to assess the degree of atherosclerotic disease and cardiovascular risk. This study highlights the role of different kinds of biomarkers, showing their usefulness and potentiality in multi-district atherosclerotic patients, especially for early diagnosis and therapy effectiveness monitoring. A retrospective analysis performed from September 2021 to August 2022, of patients with carotid artery disease, was performed. A total of 341 patients with a mean age of 53.8 years were included in the study. The outcomes showed an increased risk of stroke in patients with significative carotid artery disease, nonresponsive to therapy, monitored through a series of serum biomarkers (homocysteine, C-reactive protein, and oxidized LDL). In this reported experience, the systematic use of DUS in association with the multiple biomarkers approach was effective for the early identification of patients at higher risk of disease progression or inefficient therapy.

Natural distemper infection in stone martens (Martes foina): From infection to neutralizing antibodies.

We report an outbreak of canine distemper virus (CDV) among stone martens (Martes foina) in Italy. After being rescued in Northern Italy between April and June 2018, six subjects were kept in a wildlife and exotic animal rescue center in Bologna province. Subjects have been monitored for 15 months in captivity. Within this time-lapse, two subjects died, while among the remaining four, only one showed clinical symptoms referable to distemper. Surviving subjects have been regularly tested for CDV by means of reverse transcriptase-PCR from conjunctival and oropharyngeal swabs for eleven months. The identified viruses belonged to the Wildlife-Europe CDV genetic subgroup. Neutralizing antibodies were detected at the end of the eleven months, when all subjects tested reverse transcriptase-PCR negative. Our findings confirm the circulation of the Wildlife-Europe CDV genetic subgroup (Europe 1/South America 1 lineage) within the Italian wildlife, and improve knowledge on viral infection in stone martens.

How preconditioning and pretensioning of grafts used in ACLigaments surgical reconstruction are influenced by their mechanical time-dependent characteristics: Can we optimize their initial loading state?

PURPOSE: Consensus about a pre-implant preparation protocol adaptable to any graft used in Anterior Cruciate Ligament reconstruction is still lacking. In fact, there is not agreement on reliable metrics that consider both specific graft dimensional characteristics, such as its diameter, and the inherent properties of its constitutive material, i.e. ligaments or tendons. Aim of the present study was to investigate and propose the applied engineering stress as a possible metrics. METHODS: Preconditioning and pretensioning protocol involved groups of grafts with different section (10 or 32 mm2) and materials (i.e. human patellar and hamstring tendons, and synthetic grafts). A 140 N load was applied to the grafts and maintained for 100 s. Initial stress and following stress-relaxation (a mechanical characteristic that can be related to knee laxity) were specifically analysed. FINDINGS: Initial stress, ranging between 4 and 12 MPa, was affected primarily by the graft cross-section area and secondarily by the choice of the graft material. In terms of loss of the initial stress, stress-relaxation behaviour varied instead on a narrower range, namely 13-17%. INTERPRETATION: Engineering stress can be identified as the correct metrics to optimize the initial state of each graft to avoid excessive stiffness, laxity or fatigue rupture phenomena.

Enhanced In Situ Availability of Aphanizomenon Flos-Aquae Constituents Entrapped in Buccal Films for the Treatment of Oxidative Stress-Related Oral Diseases: Biomechanical Characterization and In Vitro/Ex Vivo Evaluation.

In recent years, the key role of oxidative stress in pathogenesis of oral diseases has been emphasized and the use of antioxidant agents has been encouraged. Aphanizomenon flos-aquae (AFA) is a unicellular blue-green alga with antioxidant and anti-inflammatory properties. The aim of this study was the formulation and characterization of mucoadhesive thin layer films loaded with AFA, finalized to the treatment of oxidative stress (OS)-related oral diseases. First, to enhance the bioavailability of AFA constituents, the raw food grade material was appropriately treated by a high frequency homogenization able to disrupt cell walls. Thus, Eudragit® E100-based buccal films were produced by the solvent casting method, containing 7% and 18% of AFA. The films, characterized by uniformity in thickness, weight, and drug content, showed low swelling degree, good muco-adhesiveness and controlled drug release. The mechanical tests showed elastic moduli of films of almost 5 MPa that is well-suitable for human buccal applications without discomfort, besides biaxial tests highlighted a marked material isotropy. Permeation studies through porcine mucosae demonstrated the ability of films to promote AFA penetration in the tissues, and when sublingually administered, they produced a drug flux up to six-fold higher than an AFA solution. The new formulations represent an interesting alternative for the development of cosmetics and nutraceuticals with a functional appeal containing plant extracts.

Multifibrillar bundles of a self-assembling hyaluronic acid derivative obtained through a microfluidic technique for aortic smooth muscle cell orientation and differentiation.

A hyaluronic acid derivative that is able to physically crosslink in a saline aqueous environment was employed for the production of fibers with a mean diameter of 50 µm using a microfluidic technique. The microfibers were collected in a tailored rotating collector and assembled to form multifibrillar bundles. The orientation of the microfibers on the collected bundles was evaluated by microCT analysis. The bundles were biofunctionalized by physical addition of fibronectin or chemical tethering of a cyRGDC peptide to achieve control of Aortic Smooth Muscle Cell (AoSMC) attachment, elongation and alignment. The mechanical performances of these bundles were evaluated by elongation tests, related to the kind of biological functionalization and compared to non-functionalized samples. The alignment and differentiation of AoSMCs on single fibers and on the bundles were evaluated by microscopy and histochemical analyses.

[Characteristics of unconventional medicine users and their households in Italy]. / Caratteristiche individuali e familiari degli utilizzatori di terapie non convenzionali in Italia.

The results presented in this paper are part of the largest survey on unconventional medicine conducted so far (more than 140 000 people). Families with high socio-economical levels had the highest probability of choosing unconventional medicine. The use is strongly related to geographic area probably due to different availability of structures able to provide these therapies. At individual level the choice to use unconventional medicine seems a "cultural" trend associated with healthy life styles, and with positive attitudes towards prevention. It is interesting also to underline that the use of unconventional medicine is more frequent among women. Almost all users of unconventional medicine (80%) declare to be in good health, and this can indicate that unconventional therapies are mostly used for not serious and self limited conditions. Furthermore, use of unconventional medicine is often associated with a greater use of conventional drugs and with a greater frequency of check-up. This suggests a "complementary", more than "alternative" use of this kind of therapies.

Use of unconventional medicine in Italy: a nation-wide survey.

OBJECTIVE: To investigate the prevalence of use of unconventional therapies in Italy, the main health problems associated with and the motivations for use of these therapies. METHODS: Questions about the use of unconventional therapies were inserted in a nation-wide survey conducted by face-to-face interviews with all members of sampled families by the National Institute of Statistics during four quarters of the years 1999-2000. Data presented here are based on the results of the first two quarters of the survey (September and December 1999) during which a representative sample of 30,000 Italian families (70,898 individuals) was interviewed. RESULTS: Almost 9 million people (15.6% of the Italian population) used at least one unconventional therapy during the period 1997-1999. Homeopathy was the most frequently used (8.2% of the population), followed by manual treatments (7%), herbal medicine (4.8%) and acupuncture (2.9%). Homeopathy was also quite commonly used by children (7.7% of Italian children). The main reason for use was concern about potential toxicity of "conventional medicine". The health problem most frequently treated with all kinds of unconventional therapies was pain. CONCLUSIONS: Use of unconventional therapies has almost doubled since 1991. However, with 15.6% of the Italian population (9 million people) using at least one therapy, Italy ranks among the "light" users compared with other European countries. Homeopathy is the most frequently used therapy. The typical user is, as in other western countries, a highly educated woman aged 35-44 years and resident in the richest part of the country (north-eastern Italy).
