Perceived health status and satisfaction with healthcare services of detained male individuals: a survey in Italy.

OBJECTIVES: This study investigated the perceived health status and satisfaction with prison healthcare services of detained male individuals in Italy. STUDY DESIGN: A cross-sectional study was performed between March and June 2021. METHODS: Of 800 male detained individuals who were invited to participate in the study, 632 returned the self-administered questionnaire, resulting in a response rate of 79%. RESULTS: Overall, 72.8% of participants reported that they were moderately or completely satisfied with their health status, and 27.2% stated that they were not at all satisfied. Moreover, 66.2% of participants reported that they had at least one health problem or disease, compared with 34% at the time of incarceration, with 35% reporting multiple health problems/diseases. In total, 10.1% of participants requested healthcare when a health problem occurred, and 12.4% were always satisfied with the healthcare that they received. Significant determinants of dissatisfaction with health status were older age, reported health problems/diseases, suicide attempts, emotional problems and no working activity in prison. Significant determinants of dissatisfaction with healthcare services were younger age, health problems at incarceration, suicide attempts and multiple experiences of incarceration. CONCLUSIONS: This study shows that detained male individuals have multiple and frequently unmet health needs. Some of the reported health problems or diseases were present at the time of incarceration, but these often worsened and/or increased during detention. This study highlights the need to promote evidence-based intervention to strengthen the role of healthcare services provided in prisons.

Large-scale phylogenomic analysis reveals the phylogenetic position of the problematic taxon Protocruzia and unravels the deep phylogenetic affinities of the ciliate lineages.

The Ciliophora is one of the most studied protist lineages because of its important ecological role in the microbial loop. While there is an abundance of molecular data for many ciliate groups, it is commonly limited to the 18S ribosomal RNA locus. There is a paucity of data when it comes to availability of protein-coding genes especially for taxa that do not belong to the class Oligohymenophorea. To address this gap, we have sequenced EST libraries for 11 ciliate species. A supermatrix was constructed for phylogenomic analysis based on 158 genes and 42,158 characters and included 16 ciliates, four dinoflagellates and nine apicomplexans. This is the first multigene-based analysis focusing on the phylum Ciliophora. Our analyses reveal two robust superclades within the Intramacronucleata; one composed of the classes Spirotrichea, Armophorea and Litostomatea (SAL) and another with Colpodea and Oligohymenophorea. Furthermore, we provide corroborative evidence for removing the ambiguous taxon Protocruzia from the class Spirotrichea and placing it as incertae sedis in the phylum Ciliophora.

Einstein-Podolsky-Rosen spatial entanglement in ordered and anderson photonic lattices.

We demonstrate quantum walks of a photon pair in a spatially extended Einstein-Podolsky-Rosen state coupled into an on-chip multiport photonic lattice. By varying the degree of entanglement we observe Anderson localization for pairs in a separable state and Anderson colocalization for pairs in an Einstein-Podolsky-Rosen entangled state. In the former case, each photon localizes independently, while in the latter neither photon localizes, but the pair colocalizes--revealing unexpected survival of the spatial correlations through strong disorder.

Human papillomavirus and vaccination: knowledge, attitudes, and behavioural intention in adolescents and young women in Italy.

This study assesses knowledge, attitudes, and behavioural intention towards human papillomavirus (HPV) infection and vaccination in a random sample of 1348 adolescents and young women aged 14-24 years in Italy. A self-administered anonymous questionnaire covered demographics; knowledge about HPV infection, cervical cancer, and HPV vaccine; the perceived risk for contracting HPV infection and/or for developing cervical cancer, the perceived benefits of a vaccination to prevent cervical cancer, and willingness to receive an HPV vaccine. Only 23.3% have heard that HPV is an infection of the genital mucosa and about cervical cancer. Those older, with at least one parent who is a health care professional, with personal, familiar, or friendly history of cervical cancer, and having underwent a health checkup in the last year with information about HPV vaccination were significantly more knowledgeable. Risk perception scores (range: 1-10) of contracting HPV infection and of developing cervical cancer were 5.8 and 6.5. Older age, not having a parent who is a health care professional, having had a personal, familiar, or friendly history of cervical cancer, and need of additional information were predictors of the perceived susceptibility of developing cervical cancer. The vast majority professed intent to receive an HPV vaccine and the significant predictors were having at least one parent who is a health care professional, a high perceived risk of contracting HPV infection and of developing cervical cancer, and a high belief towards the utility of a vaccination for preventing cervical cancer. Knowledge about HPV infection and cervical cancer should be improved with more attention to the benefit of HPV vaccination.

Amyand's hernia: case report and review of the literature.

The authors report a case of gangrenous acute appendicitis in the sac of an inguinal hernia (Amyand's hernia). After a review of the literature, they emphasise the extreme rarity of the case reported, they underline how the clinical picture is highly similar to that of a strangulated inguinal hernia. They affirm that appendicectomy and hernioplasty may be performed at the same time, since the repair of the hernia should be performed without prosthesis implantation due to the contamination of the operating field.

[Surgery of inguinal hernia in the elderly]. / La chirurgia dell'ernia inguinale nel paziente geriatrico.

The authors report their 14 years experiences with inguinal hernia repair in elderly. The result were compared with young (< 75 years old), and confirmed that there were no significant differences between the 2 groups. The study confirmed the safety and effectiveness of the "tension-free" technique under local anaesthesia, which is proposed as the treatment of choice in elderly.

Experimental inhibition of decoherence on flying qubits via "bang-bang" control.

Decoherence may significantly affect the polarization state of optical pulses propagating in dispersive media because of the unavoidable presence of more than a single frequency in the envelope of the pulse. Here we report on the suppression of polarization decoherence in a ring cavity obtained by properly retooling for photonic qubits the "bang-bang" protection technique already employed for nuclear spins and nuclear-quadrupole qubits. Our results show that bang-bang control can be profitably extended to quantum information processes involving flying polarization qubits.

Cytotoxic effects and apoptotic signalling mechanisms of the sesquiterpenoid euplotin C, a secondary metabolite of the marine ciliate Euplotes crassus, in tumour cells.

Most antitumour agents with cytotoxic properties induce apoptosis. The lipophilic compound euplotin C, isolated from the ciliate Euplotes crassus, is toxic to a number of different opportunistic or pathogenic microorganisms, although its mechanism of action is currently unknown. We report here that euplotin C is a powerful cytotoxic and pro-apoptotic agent in mouse AtT-20 and rat PC12 tumour-derived cell lines. In addition, we provide evidence that euplotin C treatment results in rapid activation of ryanodine receptors, depletion of Ca2+ stores in the endoplasmic reticulum (ER), the release of cytochrome c from the mitochondria, activation of caspase-12, and activation of caspase-3, leading to apoptosis. Intracellular Ca2+ overload is an early event which induces apoptosis and is parallelled by ER stress and the release of cytochrome c, whereas caspase-12 may be activated by euplotin C at a later stage in the apoptosis pathway. These events, either independently or concomitantly, lead to the activation of the caspase-3 and its downstream effectors, triggering the cell to undergo apoptosis. These results demonstrate that euplotin C may be considered for the design of cytotoxic and pro-apoptotic new drugs.

Glycogen phosphorylase activity in the liver of the frog Rana esculenta.

1. Phosphorylase activity has been assayed in liver extracts of the frog, Rana esculenta, during the winter period. In native conditions, most of the phosphorylase is present as AMP-independent activity and shows properties similar to those of the a form of the liver enzyme from other vertebrates. 2. It is suggested that regulation of phosphorylase activity is through interconversion between a and b forms operated by endogenous phosphorylase kinase and phosphatase. 3. Kinetic studies show hyperbolic saturation curves for glycogen with apparent Km of 2.91 mM and 9.67 mM for a and b forms, respectively. 4. A hyperbolic saturation curve is also observed for glucose 1-P in the case of phosphorylase a, with an apparent Km of 3.95 mM, whereas a sigmoidal kinetic is shown by the b form for the same substrate; from Hill plots an S0.5 of 24.2 mM was derived. 5. Hyperbolic responses were observed in the case of AMP, and Ka of 70 microM and 0.31 mM were calculated for phosphorylase a and b, respectively.

Multiparticle quantum superposition and stimulated entanglement by parity selective amplification of entangled states.

We report the creation of an entangled multiphoton quantum superposition by quantum injection of entangled 2-photon states into a parity selective parametric amplifier. The information preserving property of the state transformation suggests for these macrostates the name of large qubits. They are ideal objects for investigating the emergence of the classical world in complex quantum systems and have relevant new applications in quantum information.

Molecular cloning of the gene encoding an acidic ribosomal protein of the P2 family from the ciliate Euplotes raikovi.

We have characterized a macronuclear gene of the ciliate protozoan Euplotes raikovi, which encodes an acidic ribosomal protein of the P protein family. This gene shows the typical organization of the hypotrich ciliate macronuclear "gene-sized" molecules with Euplotes telomeres at the ends. The longest open reading frame encodes a conceptual protein of 113 amino acid residues, with a molecular mass and pI value of 11.45 kDa and 3.97, respectively. By using sequence homology analysis, the protein was found to belong to the ribosomal P2 protein family and was named Er P2, where Er stands for Euplotes raikovi. These proteins, generally called A (acidic/alanine rich) proteins in prokaryotes and P (phosphorylated) proteins in eukaryotes, in which they are divided into P1 and P2 families, play a role in the elongation step of protein synthesis. Approximately 40% amino acid sequence identity was found between the cloned protein and other known protozoan ribosomal P2 proteins. Within its N-terminal half, this protein contains several potential kinase phosphorylation sites. Protein Er P2 differs markedly from the consensus P protein sequence in its C-terminal region, usually highly conserved among eukaryotic ribosomal P proteins, and shows similarities with the C-terminus of the archaebacterial ribosomal A proteins. To our knowledge, this E. raikovi protein represents the first demonstration of a ribosome-associated protein of the P2 family in a ciliate protozoan.

Identification of the tubulin gene family and sequence determination of one beta-tubulin gene in a cold-poikilotherm protozoan, the antarctic ciliate Euplotes focardii.

Four different tubulin genes were identified in the somatic nucleus (macronucleus) of Euplotes focardii, a strictly cold-adapted, Antarctic ciliate: one of 1,800 bp for alpha-tubulin and three of 2,150, 1,900, and 1,600 bp, respectively, for beta-tubulin. Preliminarily analysed for restriction fragment length polymorphisms, these genes showed remarkable differences in organisation from tubulin genes of other ciliates which live in temperate areas and were analysed in parallel with E. focardii. The complete coding sequence of the 1,600 bp beta-tubulin gene was then determined and shown to contain unique structural features of potential importance for E. focardii microtubule organization and activity. Of eight unique substitutions detected, seven were concentrated in the large amino terminal domain of the molecule that directly interacts with the carboxy terminal region of alpha-tubulin for heterodimer formation. Sequence analysis of the cloned gene revealed, in addition, a potential new exception in the use of the genetic code by ciliates. A TAG codon was aligned in correspondence with Trp-21 which is strictly conserved in every tubulin sequence so far determined.
