Coronavirus–associated enteritis in a quail farm
An enteric syndrome observed in semi-intensively reared quails is described. The affected birds showed depression, severe diarrhoea and dehydration. The mortality occurred particularly in young birds. At necropsy, the prominent lesion was catarrhal enteritis. Laboratory investigations demonstrated the presence of coronavirus in the gut of dead animals. No additional pathogens were detected. To our knowledge, this is the first evidence for the presence of CoVs in quail with enteritis
Chemotherapy-free treatments: are we ready for prime time?
Epithelial ovarian cancer (EOC) is most frequently diagnosed at
an advanced stage and, despite high response rates to initial
taxane-platinum-based chemotherapy, more than 70% of
patients will develop recurrent disease and will receive several
chemotherapy treatments. At present, the 5-year overall survival
(OS) for women diagnosed with stage III–IV disease is 46% and
patients with genetic impairments of DNA repair pathways
[BRCA mutations and in general homologous recombination deficiency (HRD)] live longer and possibly will receive even more
lines of chemotherapy
Hyaluronic Acid Fillers Enriched with Glycine and Proline in Eyebrow Augmentation Procedure
Background: The eyebrow area is a clinically critical district due to the anatomical complexity and the propensity to aging-related atrophy. Hyaluronic acid fillers have been proposed to recover the dermal volume of the facial and lips regions.
Aim: The aim of the present investigation was to evaluate hyaluronic acid fillers enriched with glycine and proline for the treatment of eyebrow augmentation.
Methods: A total of 15 healthy patients were treated with eyebrow augmentation procedure. The distance between mid-bipupil to lateral eyebrow and mid-eyebrow to the medial eyebrow was measured before, immediately after treatment and at follow-up of 6 months.
Results: The healing period was uneventful, and no evidence of inflammation or swelling associated with the treatment was reported. No macroscopical alteration was reported in the surrounding tissues with no evidences of visible wheals or lumps in the treated sites at the follow-up. Before treatment, the angle was equal to 9.32 ± 0.2°, while after treatment it was 11.21 ± 0.4° (p < 0.01); after three and 6 weeks, it was, respectively, 10.66 ± 0.2° (p<0.05) and 10.02 ± 0.3°(p > 0.05).
Conclusions: The study results suggest that the hyaluronic acid fillers enriched with glycine and proline treatment resulted as being a useful procedure for augmentation, contour and volume definition and elevation of the eyebrow region with a high-level aesthetic result
Survival Rate of Zygomatic Implants for Fixed Oral Maxillary Rehabilitations: A Systematic Review and Meta-Analysis Comparing Outcomes between Zygomatic and Regular Implants
Background: Zygomatic implants have been proposed alone or in combination with premaxillary conventional implants for severe resorbed maxillary atrophy rehabilitation. The aim of the present investigation was to evaluate through a qualitative systematic review and metaanalysis the survival rate of zygomatic implants in conjunction with regular fixtures for maxillary rehabilitation.
Methods: The article screening was conducted on the PubMed/Medline and EMBASE electronic databases according to the “Preferred Reporting Items for Systematic Reviews and Meta-Analyses” (PRISMA) guidelines. The scientific papers were included for qualitative analysis and risk-of-bias evaluation. Only the papers that included rehabilitation with zygomatic implants in combination with regular implants were considered for the meta-analysis comparative evaluation of the implant survival rate.
Results: The paper search screened a total of 137 papers. After the initial screening, a total of 32 articles were considered for the qualitative analysis. There was a similar implant survival rate between zygomatic and premaxilla regular implants (p = 0.02; Z: 2.26).
Conclusions: Zygomatic and conventional implants showed a high long-term survival rate for fixed maxillary rehabilitations, but few included studies reported the marginal bone loss after loading. Further studies are necessary to evaluate the pattern of marginal bone loss between zygomatic and conventional implants after long-term functional loading
End-User Development for Artificial Intelligence: A Systematic Literature Review
In recent years, Artificial Intelligence has become more and more relevant in
our society. Creating AI systems is almost always the prerogative of IT and AI
experts. However, users may need to create intelligent solutions tailored to
their specific needs. In this way, AI systems can be enhanced if new approaches
are devised to allow non-technical users to be directly involved in the
definition and personalization of AI technologies. End-User Development (EUD)
can provide a solution to these problems, allowing people to create, customize,
or adapt AI-based systems to their own needs. This paper presents a systematic
literature review that aims to shed the light on the current landscape of EUD
for AI systems, i.e., how users, even without skills in AI and/or programming,
can customize the AI behavior to their needs. This study also discusses the
current challenges of EUD for AI, the potential benefits, and the future
implications of integrating EUD into the overall AI development process.Comment: This version did not undergo peer-review. A corrected version is

Microbiota of the Tongue and Systemic Connections: The Examination of the Tongue as an Integrated Approach in Oral Medicine
The tongue is able to quickly reflect the state of health or disease of the human body. Tongue inspection is an important diagnostic approach. It is a unique method that allows to explore the pathogenesis of diseases based on the guiding principles of the holistic concept that involves the observation of changes in the lining of the tongue in order to understand the physiological functions and pathological changes of the body. It is a potential method of screening and early detection of cancer. However, the subjective inspection of the tongue has a low reliability index, and therefore computerized systems of acquisition of diagnostic bioinformation have been developed to analyze the lining of the tongue. Next-generation sequencing technology is used to determine the V2–V4 hypervariable regions of 16S rRNA to study the microbiota. A lot of neoplasms are identified only at an advanced phase, while in the early stages, many subjects remain in an asymptomatic form. On the contrary, the early diagnosis is able to increase the prognosis of cancer and improve the survival rates of subjects. Evidently, it is necessary to develop new strategies in oral medicine for the early diagnosis of diseases, and the diagnosis of the tongue as a minimally invasive method is certainly one of them
Static Crow’s Feet Treated with Voltaic Arc Dermabrasion (Atmospheric Plasma): Post-Operative Pain Assessment by Thermal Infrared Imaging
Background: In the literature, several strategies have been described for the treatment of unaesthetic marks on the face resulting from the aging processes. The atmospheric plasma procedure is a non-invasive, inexpensive technique proposed for the rejuvenation of facial tissues. The aim of this study was to evaluate the performance of voltaic arc dermabrasion (VAD) for the treatment of static crow’s feet of the periorbital area. Methods: The crow’s feet of 135 patients (127 female and 8 male) were treated using the VAD technique. The perioperative skin temperature measurement was assessed using an Infrared Temperature sensor. The pain was measured using the Visual Analogic Score (VAS) at 1 week, 1 month and 1 year. The patient’s and surgeon’s satisfaction were assessed using the Global Aesthetic Improvement Scale (GAIS) at 1 month and 1 year from the procedure. The severity of the crow’s feet was rated using the Crow’s Feet Grading Scale (CFGS). Results: A complete epidermal healing of all the subjects treated was evident at 7 days. The atmospheric plasma technique showed an efficient treatment for the removal of the crow’s feet, with a good aesthetic outcome, high surgeon and patient satisfaction, without clinical complications. Conclusions: The atmospheric plasma technique can be a useful modality in the cosmetic as well as therapeutic treatment of crow’s feet
Effects of polluted air-masses advection on atmospheric particles in a semi-rural site in south Italy by SEM-EDX analysis
The variation of aerosol properties under polluted air masses advection was studied in a semi-rural site in South Italy, by means of SEM-EDX analysis performed on particles collected on 13-stages impactor filters. Radiometric measurements, HYSPLIT back-trajectories and NAAPS maps helped to choose four measurement days of polluted air mass circulation, two of them collected in the warm season (31 July 2008, 16 September 2010) and two in the cold one (16 April 2009, 18 March 2010). Polluted aerosol characteristics were compared to those under background (BG) conditions (8 February 2011), highlighting differences in the particles chemical and morphological properties. One of the signatures of the air mass transport in the coarse fraction was the higher content of particles containing S, i.e., S-reacted, (27.5% on average) in comparison with BG conditions (1%). Two main sources of transported aerosols were identified: industrial processes and biomass burning, with fly ash, metal and S-rich particles in the first case, and K-salts and nitrate-coated Ca-bearingparticles in the second. Single particle analysis on the coarse fraction allowed large agglomerates of soot to be identified, with inclusions of silicate particles rich in Cu and Zn, Ca-S, fly ash and metals particles that are a clear indication of extensive modifications of aerosol size, chemical composition and, likely, radiative properties. In finer stages (EAD ≤ 0.94 μm) concurrent collection of organic and inorganic particles originated an agglomerate state matter mainly characterized by K and S for polluted conditions and by K only for BG
Synthetic Scaffold/Dental Pulp Stem Cell (DPSC) Tissue Engineering Constructs for Bone Defect Treatment: An Animal Studies Literature Review
Background: Recently a greater interest in tissue engineering for the treatment of large bone defect has been reported. The aim of the present systematic review and meta-analysis was to investigate the effectiveness of dental pulp stem cells and synthetic block complexes for bone defect treatment in preclinical in vivo articles.
Methods: The electronic database and manual search was conducted on Pubmed, Scopus, and EMBASE. The papers identified were submitted for risk-of-bias assessment and classified according to new bone formation, bone graft characteristics, dental pulp stem cells (DPSCs) culture passages and amount of experimental data. The meta-analysis assessment was conducted to assess new bone formation in test sites with DPSCs/synthetic blocks vs. synthetic block alone.
Results: The database search identified a total of 348 papers. After the initial screening, 30 studies were included, according to the different animal models: 19 papers on rats, 3 articles on rabbits, 2 manuscripts on sheep and 4 papers on swine. The meta-analysis evaluation showed a significantly increase in new bone formation in favor of DPSCs/synthetic scaffold complexes, if compared to the control at 4 weeks (Mean Diff: 17.09%, 95% CI: 15.16–18.91%, p < 0.01) and at 8 weeks (Mean Diff: 14.86%, 95% CI: 1.82–27.91%, p < 0.01) in rats calvaria bone defects.
Conclusion: The synthetic scaffolds in association of DPSCs used for the treatment of bone defects showed encouraging results of early new bone formation in preclinical animal studies and could represent a useful resource for regenerative bone augmentation procedure
Protective Face Masks: Effect on the Oxygenation and Heart Rate Status of Oral Surgeons during Surgery
Background: Safety in medical work requires eye protection, such as glasses, and protective facial masks (PFM) during clinical practice to prevent viral respiratory infections. The use of facial masks and other full personal protective equipment increases air flow resistance, facial skin temperature and physical discomfort. The aim of the present study was to measure surgeons’ oxygenation status and discomfort before and after their daily routine activities of oral interventions. Methods: 10 male voluntary dentists, specializing in oral surgery, and 10 male voluntary doctors in dentistry, participating in master’s courses in oral surgery in the Department of Oral Surgery of the University of Chieti, with mean age 29 ± 6 (27–35), were enrolled. This study was undertaken to investigate the effects of wearing a PFM on oxygenation status while the oral surgeons were actively working. Disposable sterile one-way surgical paper masks (Surgical Face Mask, Euronda, Italy) and FFP2 (Surgical Face Mask, Euronda, Italy) were used and the mask position covering the nose did not vary during the procedures. The FFP2 was covered by a surgical mask during surgical treatment. A pulse oximeter was used to measure the blood oximetry saturation during the study. Results: In all 20 surgeons wearing FFP2 covered by surgical masks, a reduction in arterial O2 saturation from around 97.5% before surgery to 94% after surgery was recorded with increase of heart rates. A shortness of breath and light-headedness/headaches were also noted. Conclusions: In conclusion, wearing an FFP2 covered by a surgical mask induces a reduction in circulating O2 concentrations without clinical relevance, while an increase of heart frequency and a sensation of shortness of breath, light-headedness/headaches were recorded
