Abstract
Abstract
Background
HIV-infected patients display an increased risk of cardiovascular events. HIV and antiretroviral therapy (ART) have both been suggested to increase the risk of cardiovascular events but their specific role remains unclear.
Purpose
The aim of this study was to analyse the metabolomic profile in a cohort of HIV-free, ART experienced and naïve HIV-infected patients and to identify the metabolite associated with atherosclerosis development and endothelial dysfunction. The impact of ART on inflammatory and autoimmune biomarkers known to underlie atherosclerosis burden was also investigated.
Methods
144 participants from a South African cohort were divided in three groups: HIV-free (n=50), HIV-infected/ART experienced (n=50) and HIV-infected/ART naïve (n=44). Targeted metabolomic analyses were performed using standard operating procedures. Atherosclerosis development was evaluated using coronary intima-media thickness (CITM) and endothelial dysfunction by flow-mediated dilation (FMD). Inflammatory biomarkers were measured with the Meso Scale Discovery® platform. The levels of autoantibodies against apolipoprotein A1 (anti-apoA1 IgG) and its specific C-terminal domain (anti-F3L1) levels were assessed by homemade ELISA assays.
Results
257 endogenous metabolites were identified in the 144 samples. Regarding the association of metabolites with the vascular markers, eight metabolites were found to be associated with FMD and eleven with CIMT. Among these metabolites, cytosine was negatively correlated with FMD (r=−0.22, p=0.009), while positively with CIMT (r=0.20, p=0.026). Interestingly, from the list of these 18 metabolites, ART-experienced patients displayed an increase in kynurenine (p=0.0007) and 3–2-hydroxyphenyl-propanoate (p=0.0009) levels and a decrease in itaconate (p=0.021) levels compared to ART-naïve patients. HIV-infected patients displayed a more proatherogenic profile compared to HIV-free subjects. Inflammatory markers (IFNg, IL-6, IL-10, TNFα, CRP all p<0.05), circulating adhesion molecules (ICAM-1 and VCAM-1, p<0.05), anti-apoA1 IgG and anti-F3L1 (p<0.05) and CIMT (p=0.05) were increased while FMD (p=0.054) was decreased in HIV-infected patients compared to HIV-free participants. While ART treatment significantly reduced IFNg, IL-10, TNFα, VCAM-1, anti-apoA1 IgG and anti-F3L1, no significant differences were observed in other biomarkers between ART-experienced and naïve participants.
Conclusion
Metabolomic analysis identified metabolites that were differentially expressed in the 3 groups. 18 metabolites were significantly correlated with FMD or CITM, among which the levels of kynurenine, 3–2-hydroxyphenyl-propanoate and itaconate were modulated by ART. HIV patients displayed increased levels of inflammatory markers, circulating adhesion molecules and anti-apoA1 IgG which was downregulated by ART.

Abstract
Abstract
Aims
Autoantibodies against apolipoprotein A-1 (anti-apoA-1 IgGs) have emerged as an independent biomarker for cardiovascular disease and mortality in humans, promote death in ApoE−/− mice, and seem to be preferentially oriented against the c-terminal part of apoA-1 (cterA1). Corresponding specific mimetic peptides were shown to reverse anti-apoA-1 IgG pro-inflammatory effects in vitro. We evaluated the association of IgG against c-terminus apoA-1 (anti-cterA1 IgGs) with all-cause mortality in the community and tested the ability of two cterA1 mimetic peptides to reverse the anti-apoA-1 IgG-induced inflammation in vitro and mortality in ApoE−/− mice.
Methods
Anti-cterA1 IgGs were measured on serum samples of 5220 consecutive participants included in the CoLaus study with median follow-up duration of 5.6 years. The primary study outcome was all-cause mortality. Two chemically engineered optimized cterA1 mimetic peptides were tested i) on HEK cells to modulate interleukin-8 (IL-8) and tumor necrosis-alpha (TNF-α) production, and ii) in apoE−/− mice exposed to 16 weeks of anti-apoA-1 IgG passive immunisation.
Results
Anti-cterA1 IgG independently predicted all-cause mortality, each standard deviation of anti-cterA1 IgG being associated with a 18% increase in mortality risk (Hazard Ratio:1.18, 95%confidence intervals:1.04–1.33; p=0.009). Both cterA1 mimetic peptides reduced the anti-apoA-1 IgG-induced inflammation in a dose-dependent manner in vitro, but did not rescue the anti-apoA-1 IgG-associated mortality in mice.
Conclusions
Anti-cterA1 IgG independently predict all-cause mortality in the general population. By failing to reverse the anti-apoA-1 IgG-induced mortality in mice, our data do not support the hypothesis that these autoantibodies could be actionable through cognate peptides immunomodulation.

Abstract
Osteoid osteomas are benign but painful bone-forming tumors usually involving long bones, with localization at the spine in 10-20% of the cases. The most common symptom is back pain responding to nonsteroidal anti-inflammatory drugs, but in some cases, also radicular pain can be present. For years, surgical excision has been considered the best choice of treatment for cases with unresponsive pain and has been practiced with a high percentage of success but also a high rate of fusion with instrumentation. In the last years, percutaneous radiofrequency ablation has been proposed as a new mini-invasive technique for the treatment of osteoid osteomas.

Abstract
AIM The aim of this review is to quantify the prevalence and type of malocclusion among children and adolescents during the different stages of dentition worldwide. MATERIALS AND METHODS Recent studies (from 2009 to 2019), published in Medline, Web of Science and Embase and orthodontic text-books have been comprehensively reviewed herein. The methodological quality of the included studies was assessed using STROBE criteria. RESULTS After screening 450 records and analysing 284 relevant full-text publications, 77 studies were included in this review. A good degree of evidence was obtained due to the medium-high methodological quality level of included studies. The worldwide prevalence of malocclusion was 56% (95% CI: 11-99), without differences in gender. The highest prevalence was in Africa (81%) and Europe (72%), followed by America (53%) and Asia (48%). The malocclusion prevalence score did not change from primary to permanent dentition with a common score of 54%. Malocclusion traits such as Angle's classes, overjet, overbite, and asymmetrical midline shift essentially did not change their prevalence during different dentitions. Conversely, traits such as cross-bite and diastema reduced their prevalence during permanent dentition, while scissor-bite and dental crowding increased their scores. CONCLUSION The worldwide high prevalence of malocclusion and its early onset during childhood should induce policymakers as well as paediatric physicians and dentists to devise policies and adopt clinical strategies for preventing malocclusion since younger children's ages.

Abstract
AIM Caries lesions begin with enamel acid demineralisation mediated by microorganisms. Lasers with sub-ablative energy might act as a prophylactic intervention to reinforce enamel against lesions caused by acid. MATERIALS AND METHODS A systematic review of the literature was performed evaluating only in vitro studies published from 2010 to 2018. The research was performed using the following databases: Medline, Embase and the Web Of Science. A further search was performed consulting the list of references of the included studies as well as book chapters which dealt with this topic. RESULTS A total of 347 records were retrieved and, after their evaluation, 36 studies were included. CO2 lasers were the most described and effective device in preventing acid demineralisation. This type of laser was unique in improving the already positive results obtained with fluoride-based interventions. Er,Cr:YSGG (with fluencies > 8.5J/cm2), diode and argon lasers also improved enamel acid resistance (p-values ranging from 0.05 to 0.001) producing similar effects with fluoride-based interventions. Regarding the sealant retention outcome, the Er:YAG laser was able to perform an enamel etching which was as effective as the traditional acid etching with the advantage of being easier and usually well accepted by low-compliant patients (i.e. younger children). Nd:YAG presented the worst results. The most common structural changes after the laser irradiation were water and carbonate reduction in the enamel combined with a phosphate and calcium enamel content increase. Moreover, the calcium/phosphate ratio was found to reach the 1.67 ideal ratio. CONCLUSION The in vitro studies that examined the prophylactic use of lasers for increasing enamel acid resistance presented interesting results that are enough to support a further in vivo experiment. This would entail the use of a clinical laser as an alternative or in combination with fluoride-based interventions.

Abstract
AIM Recently, the application of restorative materials containing metacrilate monomers in the conservative and paediatric dentistry has focused on the possible negative effects due to the use of these composites. In particular the release of monomers from reconstructions as a result of an insufficient polymerisation, can spread along the mucosal and dental tissues with potential immunological ed cytotoxic effects. Regarding to the importance of this issue, the aim of this study is to provide a descriptive review of the literature on potential local and systemic interactions of metacrylic and acrylic monomers with the immune system, both in vitro and in vivo. RESULTS The most highly used monomers in composite materials applied in conservative dentistry include: 2-hydroessietil- methacrylate (HEMA), triethylene glycol-dimethacrylate (TEGDMA), bisphenol A glycidyl-methacrylate (BisGMA) and urethane- dimethacrylate (UDMA). Different investigations have been performed for better understanding of the potential side effects of metacrylic monomers on immune system cells. Different factors such as cell population, exposure time and parameters more strictly connected to these materials, such as molecular weight, chemical composition and mechanical characteristics, seem to be directly involved in these reactions.

Abstract
Abstract
Background
With the access to antiretroviral therapy (ART), the mortality related to the human immunodeficiency virus (HIV) has dropped, shifting the clinical challenges towards chronic disease management, including cardiovascular disease (CVD) risk assessment. Factors that potentially contribute to the physiopathology of HIV-related CVD include the HI-virus itself, adverse effects of ART, and processes such as dyslipidemia, inflammation, immune/autoimmune activation and endothelial injury. Among autoantibodies of possible cardiovascular relevance, those directed against apolipoprotein A-1 (anti-apoA-1 IgG) were shown to predict major adverse cardiovascular events and promote atherogenesis.
Purpose
The aim of the study was to evaluate the prevalence of anti-apoA1 IgG in HIV-free and ART experienced and naïve HIV-infected patients as well as the association between anti-apoA1 IgG levels and, indices of viral suppression, clinical parameters (10 year Framingham Risk Score (FRS)) and inflammatory biomarkers, known to underlie atherosclerosis burden in these patients.
Methods
Anti-apoA1 IgG serum levels were assessed by a homemade ELISA assay in 144 participants from a South African cohort divided in three groups: HIV-free (n=50), HIV-infected/ART experienced (n=50) and HIV-infected/ART naïve (n=44). Inflammatory biomarkers were measured.
Results
HIV-infected patients displayed an increased pro-atherogenic biomarker profile compared to HIV-free subjects, but not difference in the FRS was observed between these two groups. Regarding anti-apoA1 IgG, 24% of HIV-free patients tested positive compared to 40% and 70% in HIV-infected/ART experienced and naïve groups, respectively. HIV-infected, anti-apoA1 IgG positive patients showed a significant decrease in CD4+ counts (p=0.003) and a significant increase in viremia (p=0.0130), mean heart rate (p=0.0243), albuminuria (p=0.0155), pro-inflammatory biomarkers (IFNγ, IL-10, TNFα, MIPα; all p<0.05), circulating levels of intercellular adhesion molecule (ICAM-1) (p=0.0217) and vascular cell adhesion molecule (VCAM-1) (p=0.003) compared to anti-apoA1 IgG negative ones. Of note, while this profile was maintained in HIV-infected/ART experienced, these significant differences were lost in HIV-infected/ART naïve patients. No significant difference in FRS was observed between anti-apoA1 IgG positive vs negative individuals in all groups.
Conclusions
HIV-infected patients presented with an increased prevalence of anti-apoA1 IgG compared to HIV-free subjects. In HIV-infected/ART experienced patients, anti-apoA1 IgG levels were associated with low CD4+ counts, levels of adhesion molecules and pro-inflammatory responses, features associated with increased cardiovascular events. ART highlighted pro-atherogenic differences between HIV-infected anti-apoA1 IgG negative and positive patients.

Abstract
AIM The aim of this paper was to review the published scientific literature to quantify the prevalence and mean score of dental fear/anxiety (DFA) in children/adolescents and its variation according to several variables. MATERIALS AND METHODS Cross- sectional and cohort studies published from 2000 to 2014, that measured DFA in children /adolescents (aged 0-19 years), in the general population, or visiting private or public dental services (general or pediatric) or attending school and kindergarten, were searched, with specific terms, in 3 electronic databases (Medline, Embase, Web Of Science). Primary data, collected with specific questionnaires of demonstrated reliability and/or validity, were extracted. RESULTS After screening 743 abstracts and evaluating 164 full-text publications, 36 articles were selected. Dental fear/anxiety prevalence rates were 12.2%, 10.0%, 12.2%,11.0% and 20.0% for the CFSS-DS, DAS, MDAS, DFS, and DFSS-SF scores, respectively. In the studies that used MCDAS Dental fear/prevalence rates varied from 13.3% to 29.3%. In the studies that used CFSS-DS ratings, the prevalence and the mean score of dental fear/anxiety was lower in Northern Europe than the remaining countries, the prevalence decreased with increasing age and the frequency was higher in females than males. CONCLUSIONS Dental fear/anxiety is a common problem in children/adolescents worldwide, therefore, new strategies to overcome this relevant children/adolescent condition should be encouraged.

Abstract
Two-dimensional electron gases (2DEGs) formed at oxide interfaces show a large variety of functional properties of major physical interest. Here, the peculiar electric transport behavior of the 2DEG formed at the LGO/STO oxide interface is studied under the application of light pulses of different amplitude, duration, and repetition rate, and by varying the sample temperature from 8 to 300 K. The experimental results evidence a persistent photoconductivity, intimately related to the complex physics of this system. These findings suggest the possibility of using the oxide interfaces for advanced applications as, for example, energy conversion or information storage.

Abstract
OBJECTIVE Periprosthetic joint infections (PJI) are one of the most dangerous complications in hip surgery. "Two-stage" revision surgery is the treatment of choice. Nevertheless, 5-10% of failures are reported. The aim of this study is to evaluate which factors determine the failure of the two-stage revision in patients affected by hip PJI. PATIENTS AND METHODS We retrospectively enrolled 21 patients treated for hip PJI who had undergone two-stage revision surgery. The diagnosis had been made using criteria established by the Musculoskeletal Infection Society (MSIS) and readapted by the Philadelphia Consensus Conference group. The patients underwent periodic clinical and laboratory controls after the surgical procedure. The two-stage revision treatment was considered unsuccessful in the event of re-infection or in case of severe complications occurring within one year from the treatment. RESULTS At a mean follow-up of 23.8 months 57% healed with no complications. The reinfection rate was 19% and, after the 3rd stage, the final failure rate was 9.5%. The study has shown, with statistical significance, that a greater number of previous surgical procedures (p<0.05, OR=22) and BMI>25 (p<0.05, OR=4) represent increased risk factors in predicting the failure of two-stage revision surgery. Age, CRP, ESR and a shorter lapse (<60 days) between 1st and 2nd stage were recorded in the failure cases, and have to be considered, even if not statistically significant. CONCLUSIONS Knowing the factors responsible for the increased failure of two-stage revision could lead to closer monitoring and more aggressive management in those patients expected to be at greater risk of reinfection. Obesity and multiple surgeries are risk factors for failure.

Abstract
AIM The aim of this study was to verify whether socioeconomic determinants, such as parents' educational level, family income and dental service attendance by children, are associated with the presence of caries among an Italian population of children. MATERIALS AND METHODS An observational retrospective study was carried out in a population of children aged 4-14 years who visited the Paediatric Dentistry Department of the University of Perugia, Italy. Children were stratified according to familial socioeconomic level (father's and mother's educational level, family income) and dental service attendance of children. Age- and sex- adjusted odds ratios (ORs) with 95% confidence intervals (95% CIs) were calculated by means of multivariate logistic regression models. RESULTS A sample of 231 children (mean age 8.1 yrs, SD 2.6; 127 males, 104 females) was recruited. One hundred and sixty three (70.46%) children in the study had caries. Caries presence in children was higher in children where the mothers' educational level was lower (OR =6.1; 95% CI = 3.1 to 12.7), in children where the fathers' educational level was lower (OR =2.9; 95% CI =1.6 to 5.5) and in children with lower family income (OR = 9.9; 95% 95% CI = 5.1 to 20.1). No statistically significant difference were observed in terms of caries presence between the children who were visited at least once by a dentist and children who were not previously seen by a dental practitioner (OR = 0.8; 95% CI = 0.4 to 1.6). CONCLUSION Socioeconomic level was an important predictor of caries presence among children. Both low income and low parental educational level were related to an increased presence of caries, whereas previous dental visits experience did not affect caries presence in children.

Abstract
Vortices are topological defects accounting for many important effects in superconductivity, superfluidity, and magnetism. Here we address the stability of a small number of such excitations driven by strong external forces. We focus on Abrikosov-Josephson vortex that appears in lateral superconducting S/S'/S weak links with suppressed superconductivity in S'. In such a system the vortex is nucleated and confined in the narrow S' region by means of a small magnetic field and moves under the effect of a force proportional to an applied electrical current with a velocity proportional to the measured voltage. Our numerical simulations show that when a slow moving Abrikosov-Josephson vortex is driven by a strong constant current it becomes unstable with respect to a faster moving excitation: the Josephon-like vortex. Such a current-driven transition explains the structured dissipative branches that we observe in the voltage-current curve of the weak link. When vortex matter is strongly confined phenomena as magnetoresistance oscillations and reentrance of superconductivity can possibly occur. We experimentally observe these phenomena in our weak links.

Abstract
Since 1992, the Spanish and Portuguese-Speaking Working Group of the ISFG (GHEP-ISFG) has been organizing annual Intercomparison Exercises (IEs) coordinated by the Quality Service at the National Institute of Toxicology and Forensic Sciences (INTCF) from Madrid, aiming to provide proficiency tests for forensic DNA laboratories. Each annual exercise comprises a Basic (recently accredited under ISO/IEC 17043: 2010) and an Advanced Level, both including a kinship and a forensic module. Here, we show the results for both autosomal and sex-chromosomal STRs, and for mitochondrial DNA (mtDNA) in two samples included in the forensic modules, namely a mixture 2:1 (v/v) saliva/blood (M4) and a mixture 4:1 (v/v) saliva/semen (M8) out of the five items provided in the 2014 GHEP-ISFG IE. Discrepancies, other than typos or nomenclature errors (over the total allele calls), represented 6.5% (M4) and 4.7% (M8) for autosomal STRs, 15.4% (M4) and 7.8% (M8) for X-STRs, and 1.2% (M4) and 0.0% (M8) for Y-STRs. Drop-out and drop-in alleles were the main cause of errors, with laboratories using different criteria regarding inclusion of minor peaks and stutter bands. Commonly used commercial kits yielded different results for a micro-variant detected at locus D12S391. In addition, the analysis of electropherograms revealed that the proportions of the contributors detected in the mixtures varied among the participants. In regards to mtDNA analysis, besides important discrepancies in reporting heteroplasmies, there was no agreement for the results of sample M4. Thus, while some laboratories documented a single control region haplotype, a few reported unexpected profiles (suggesting contamination problems). For M8, most laboratories detected only the haplotype corresponding to the saliva. Although the GHEP-ISFG has already a large experience in IEs, the present multi-centric study revealed challenges that still exist related to DNA mixtures interpretation. Overall, the results emphasize the need for further research and training actions in order to improve the analysis of mixtures among the forensic practitioners.
