Salute orale del figlio disabile in età evolutiva e sintomatologia depressiva della madre

Relationships between oral health status in children with disability and their mothers’ depressive symptoms Aim. The purpose of the present study was to evaluate the relationships between oral health status in children with chronic medical conditions and their mothers’ depressive symptoms. Methods. Fifty-one children (25 male and 26 female, ranging from 2 to 18 years) affected by chronic systemic diseases followed at the Sant’Orsola-Malpighi Hospital in Bologna, ,and, were referred with their mothers at the Dental Department of Bologna. Children were subclassified in 3 groups according to the ASA classification and orally examined for hygiene status, gingival condition and dental caries. The indexes used were O’Leary plaque Index (PI), bleeding on probing index (BOP), dmft/DMFT. Mothers were interviewed on knowledge about oral diseases prevention for their children and daily management (hygiene habits, sugared aliments consumption). Statistical analysis was performed through the use of linear regression. Results. The relationships between ASA and IP as well as between ASA and BOP are statistically significant (α = 0,01). Seventy percent of patients and their relatives in ASA groups 3 and 4 never received information on oral health and prevention of oral diseases by paediatricians and/or dentists. The 53% of mothers present depressive symptoms. The relationships between degree of depressive symptoms and dmft/DMFt as well as between degree of depressive symptoms and sugared aliments daily consumption are statistically significant (α = 0,05). Conclusion. Our results give support to the hypothesis of an association between degree of systemic disease and oral hygiene status. The psychological mothers condition seams to play a role on the oral conditions of their sons. Our analysis shows the needs for an interdisciplinar approach in order to promote the oral health of children with disability.

Studio osservazionale sulle complicanze della fibrillazione atriale nell'area di Bologna.

Premesse: Gli eventi ischemici (EI) e le emorragie cerebrali (EIC) sono le più temute complicanze della fibrillazione atriale (FA) e della profilassi antitrombotica. Metodi: in 6 mesi sono stati valutati prospetticamente i pazienti ammessi in uno dei PS dell’area di Bologna con FA associata ad EI (ictus o embolia periferica) o ad EIC. Risultati: sono stati arruolati 178 pazienti (60 maschi, età mediana 85 anni) con EI. Il trattamento antitrombotico in corso era: a) antagonisti della vitamina K (AVK) in 31 (17.4%), INR all’ingresso: <2 in 16, in range (2.0-3.0) in 13, >3 in 2; b) aspirina (ASA) in 107 (60.1%); c) nessun trattamento in 40 (22.5%), soprattutto in FA di nuova insorgenza. Nei 20 pazienti (8 maschi; età mediana 82) con EIC il trattamento era: a)AVK in 13 (65%), INR in range in 11 pazienti, > 3 in 2, b) ASA in 6 (30%). La maggior parte degli EI (88%) ed EIC (95%) si sono verificati in pazienti con età > 70 anni. Abbiamo valutato l’incidenza annuale di eventi nei soggetti con età > 70 anni seguiti neo centri della terapia anticoagulante (TAO) e nei soggetti con FA stimata non seguiti nei centri TAO. L’incidenza annuale di EI è risultata 12% (95%CI 10.7-13.3) nei pazienti non seguiti nei centri TAO, 0.57% (95% CI 0.42-0.76) nei pazienti dei centri TAO ( RRA 11.4%, RRR 95%, p<0.0001). Per le EIC l’incidenza annuale è risultata 0.63% (95% CI 0.34-1.04) e 0.30% (95% CI 0.19-0.44) nei due gruppi ( RRA di 0.33%/anno, RRR del 52%/anno, p=0.040). Conclusioni: gli EI si sono verificati soprattutto in pazienti anziani in trattamento con ASA o senza trattamento. La metà dei pazienti in AVK avevano un INR sub terapeutico. L’approccio terapeutico negli anziani con FA deve prevedere un’ adeguata gestione della profilassi antitrombotica.

Outcomes of global coagulation assays in patients with Philadelphia-negative myeloproliferative neoplasms with respect to genetic determinants of clonal progression

Classical myeloproliferative neoplasms (MPNs) are hematopoietic stem cell disorders that manifest with inflammation, promotion of atherosclerosis, hypercoagulability, fibrosis, and clonal evolution. The complex biological background lends itself to multi-omics studies. We have previously shown that reduced platelet fibrinogen receptor (PFR) expression may follow hyperactivation of plasma-dependent mechanisms, such as tissue factor (TF) release, unbalanced thrombin generation, involvement of protease-activated receptors (PARs). Acetylsalicylic acid (ASA) helped to restore the expression of PFRs. In this study, we enrolled 53 MPN patients, subjecting them to advanced genetic testing (panel of 30 genes in NGS), global coagulation testing (Rotational Thromboelastometry - ROTEM) and cytofluorometric determination of PFRs. ROTEM parameters appear to differ considerably depending on the type of pathology under investigation, cell count, and selected mutations. Essential thrombocythemia (ET) and CALR mutation appear to correlate with increased efficiency of both classical coagulation pathways, with significantly more contracted clot formation times (CFTs). In contrast, primary myelofibrosis (PMF) and polycythemia vera (PV) show greater imbalances in the hemostatic system. PV, probably due to its peculiar hematological features, shows a lengthening of the CFT and, at the same time, a selective contraction of parameters in INTEM with the increase of platelets and white blood cells. PMF - in contrast - seems to exploit the extrinsic pathway more to increase cell numbers. The presence of DNMT3A mutations is associated with reduced clotting time (CT) in EXTEM, while ASXL1 causes reduced maximal lysis (ML). EZH2 could be responsible for the elongation of CFT in INTEM assay. In addition, increased PFR expression is associated with history of hemorrhage and sustained CT time in FIBTEM under ASA prophylaxis. Our findings corroborate the existing models on the connection between fibrosis, genetic complexity, clonal progression, and hypercoagulability. Global coagulation assays and PFR expression are potentially useful tools for dynamic evaluation of treatments’ outcomes.

Development of a porcine lactation model for the evaluation of mammary transfer of exogenous molecules - A contribution from the conception project

Around 5 million women give birth each year in Europe and, while breastfeeding, the majority of them may need to take medications, either occasionally or continuously. Unfortunately, there is often scarce evidence of trustworthy information about how a specific molecule might affect the physiology of lactation. This is the reason that brought a European public-private partnership to fund the development of a reliable platform to provide women and health-care professionals a helpful instrument to reduce uncertainty about the effects of medication used during breastfeeding. On April 1st 2019, the ConcePTION project (Grant Agreement n°821520) started to develop such envisaged platform. The 3rd Work Package was in charge of the validation of in vitro, in vivo and in silico lactation models. Between the numerous species currently used in preclinical studies, pigs’ similarities with humans’ anatomy, physiology and genomics make them extremely useful as translational models, when proper veterinary expertise is applied. The ASA team from the University of Bologna, went first to characterize the translational lactation model using the swine species, chosen upon literature review. The aim of this work was to lay the foundations of a porcine lactation model that could be suitable for application within pharmaceutical tests, to study drug transfer through milk prior approval and commercialization. The obtained results highlighted both strengths and critical points of the study design, allowing a significant improvement in the knowledge of pharmacokinetic physiology in lactating mammals. Lastly, this project allowed the assessment of microbial changes in gut resident bacteria of newborns through an innovative in vitro colonic model. Indeed, even if there were no evident adverse effects determined by drug residues in milk, possible alterations in the delicate microbial ecology of newborns’ gastrointestinal tract was considered pivotal, giving its possible impact on the individual health and growth.
