    Objectives: Evidence on the effects of the SARS-CoV-2 Omicron variant on vaccinated and unvaccinated pregnant women is sparse. This study aimed to compare maternal and perinatal outcomes of women infected with SARS-CoV-2 during the Omicron wave in Italy, according to their vaccine protection.Methods: This national prospective cohort study enrolled pregnant women with a positive SARS-CoV-2 nasopharyngeal swab within 7 days of hospital admission between 1 January and 31 May, 2022. Women who received at least one dose of vaccine during pregnancy and those who completed the vaccine cycle with the first booster were considered protected against moderate or severe COVID-19 (MSCD). A multivariable logistic regression model evaluated the association between vaccine protection and disease severity. Maternal age, educational level, citizenship, area of birth, previous comorbidities, and obesity were analysed as potential risk factors. Results: MSCD was rare (41/2147, 1.9%; 95% CI, 1.4-2.6), and the odds of developing it were significantly higher among unprotected women (OR, 2.78; 95% CI, 1.39-5.57). Compared with protected women (n = 1069), the unprotected (n = 1078) were more often younger, with lower educational degrees, and foreigners. A higher probability of MSCD was found among women with previous comorbidities (OR, 2.86; 95% CI, 1.34-6.12) and those born in Asian countries (OR, 3.05; 95% CI, 1.23-7.56). The percentage of preterm birth was higher among women with MSCD compared with milder cases (32.0% [8/25] versus 8.4% [161/1917], p < 0.001) as well as the percentage of caesarean section (52.0% [13/25] versus 31.6% [606/1919], p 0.029). Discussion: Although severe maternal and perinatal outcomes were rare, their prevalence was significantly higher among women without vaccine protection. Vaccination during pregnancy has the potential to protect both the mother and the baby, and it is therefore strongly recommended.

    Background: Despite the growing importance given to ensuring high-quality childbirth, perinatal good practices have been rapidly disrupted by SARS-CoV-2 pandemic. This study aimed at describing the childbirth care provided to infected women during two years of COVID-19 emergency in Italy. Methods: A prospective cohort study enrolling all women who gave birth with a confirmed SARS-CoV-2 infection within 7 days from hospital admission in the 218 maternity units active in Italy during the periods February 25, 2020-June 30, 2021, and January 1-May 31, 2022. Perinatal care was assessed by evaluating the prevalence of the following indicators during the pandemic: presence of a labour companion; skin-to-skin; no mother-child separation at birth; rooming-in; breastfeeding. Logistic regression models including women' socio-demographic, obstetric and medical characteristics, were used to assess the association between the adherence to perinatal practices and different pandemic phases. Results: During the study period, 5,360 SARS-CoV-2 positive women were enrolled. Overall, among those who had a vaginal delivery (n = 3,574; 66.8%), 37.5% had a labour companion, 70.5% of newborns were not separated from their mothers at birth, 88.1% were roomed-in, and 88.0% breastfed. These four indicators showed similar variations in the study period with a negative peak between September 2020 and January 2021 and a gradual increase during the Alpha and Omicron waves. Skin-to-skin (mean value 66.2%) had its lowest level at the beginning of the pandemic and gradually increased throughout the study period. Among women who had a caesarean section (n = 1,777; 33.2%), all the indicators showed notably worse outcomes with similar variations in the study period. Multiple logistic regression analyses confirm the observed variations during the pandemic and show a lower adherence to good practices in southern regions and in maternity units with a higher annual number of births. Conclusions: Despite the rising trend in the studied indicators, we observed concerning substandard childbirth care during the SARS-CoV-2 pandemic. Continued efforts are necessary to underscore the significance of the experience of care as a vital component in enhancing the quality of family-centred care policies

    Riassunto Obiettivi Questo lavoro descrive l\u2019approccio multidisciplinare (ortodonticorestaurativo) al trattamento di una paziente con diagnosi ortodontica di III Classe dentoscheletrica in completa inversione dentale anteriore in occlusione centrica. La diagnosi restaurativa evidenziava una marcata microdonzia con morfologia dentaria alterata, assenza di punti di contatto e faccette di usura conseguenti alla malocclusione. Materiali e metodi La paziente manifestava notevoli aspettative estetiche, ma non era intenzionata a sottoporsi a intervento di chirurgia ortognatica. \uc8 stato pertanto intrapreso un trattamento ortodontico fisso di camouflage con utilizzo di minimpianti ortodontici e successivamente l\u2019applicazione di faccette adesive in ceramica integrale. Risultati I trattamenti hanno permesso un ripristino funzionale ed estetico che ha soddisfatto le aspettative del team odontoiatrico e della paziente. Conclusioni Questo caso esemplifica ed enfatizza come l\u2019approccio multidisciplinare rivesta fondamentale importanza e rappresenti l\u2019unica modalit\ue0 per ottenere risultati di eccellenza in pazienti con estetica compromessa.Objectives A multidisciplinary treatment (orthodontics-restorative) performed on a patient with dental and skeletal Class III malocclusion with anterior complete cross bite in centric occlusion is described. The restorative diagnosis showed an important microdontia with altered dental morphology, absence of contact points and abrasions on teeth due to malocclusion. Materials and methods The patient had relevant aesthetic demand but she did not want to undergo orthognatic surgery. So, a fixed orthodontic treatment and ceramic veneers has been chosen. Results Treatment restored the function and aesthetics and met the expectations of both the dental team and the patient. Conclusions This case report stresses the fact that a multidisciplinary approach is necessary to obtain the best results in patients with poor aesthetics

    Marginal fit of full-coverage crowns is a major requirement for long term success of this kind of restorations. The purpose of the study was to verify the marginal adaptation of computer assisted design (CAD)/computer assisted manufacturing (CAM) crowns on prepared teeth and on plaster dies. Within the limitations of this study, it was concluded that marginal fit of CAD/CAM restoration is within the limits considered clinically acceptable by ADA specification #8. From the results of this in vitro study, it can be stated that CAD/CAM crowns produced with DCS system show a marginal adaptation within the limits of ADA specific #8, therefore milled CAD/CAM crowns can be considered a good alternative to more traditional waxing-investing-casting techniqu

    BACKGROUND: Pancreatic adenocarcinomas are among the most aggressive types of cancer with an extremely poor diagnosis. Since this type of cancer is not well amenable to chemo- and radiotherapy or immunotherapy, surgical resection remains the only feasible treatment to date. Transforming Growth Factor (TGF)-beta and Interleukin (IL)-10 are potent immunomodulators that have been shown to suppress several aspects of the immune response. Vascular Endothelial Growth Factor (VEGF) is a powerful angiogenic factor, recently thought to be involved in neoangiogenesis and metastasis spreading. Therefore the three cytokines may contribute, by different pathways, to immune escape and growth of tumor. This study was conducted to determine the possible significance of TGF-beta1, IL-10 and VEGF as markers for monitoring the clinical course of pancreatic adenocarcinoma patients. METHODS: Cytokine serum levels were measured in 30 pancreatic cancer patients and in 30 age and sex-matched healthy subjects. RESULTS: In comparison to serum concentrations in controls, TGF-beta1, IL-10 and VEGF levels were significantly elevated in all patients. Where the patients were divided by groups on the basis of the clinical stage of the disease, no differences were observed in TGF-beta1 levels among the groups. On the contrary, IL-10 and VEGF were more represented in stage IV patients than in stage II and III patients. In addition, the 14 patients who underwent surgical resection had postoperative cytokine serum levels markedly lower than those observed at diagnosis. CONCLUSIONS: Overall, the results suggest the importance of these markers in predicting the biological activity of the disease and suggest new targets for future rational therapies

    Vascular endothelial growth factor. From basic research to clinical application

    There is increasing evidence to support the concept that growth and metastasis of solid tumors, including those of gastrointestinal tract, is facilitated by neoangiogenesis. Vascular Endothelial Growth Factor (VEGF) is one of the most powerful known inducer of endothelial cell growth. Therefore, VEGF is likely to contribute to tumor growth by promoting angiogenesis and stroma formation both directly, through its neovascularization inducing activity, and indirectly, by increasing vascular permeability. In addition, VEGF facilitates tumor diffusion favouring metastatic spread of cancer cells. In view of these implications, it is important to understand the physiopathological role played by this factor. In this review the authors present the accumulating body of data on the biological and functional properties of VEGF, paying special reference to new evidence on its contribution in tumor immune escape, through a marked inhibition of differentiation and activity of the professional antigen presenting cells (APC), namely dendritic cells (DC). As the molecular and cellular events that underlie the functional role of VEGF in tumor angiogenesis and immune suppression become better defined, rational pharmacological and/or gene therapies can be derived in order to treat those neoplasms, such as pancreatic adenocarcinoma, not well amenable to chemo- and radiotherapy or immunotherapy
