Abstract
OBJECTIVE The aim of this preclinical study was to compare the ability of tapered and cylindrical bristles to penetrate the peri-implant sulcus. METHODS A full mandibular dental arch was reproduced in plaster cast. In site #3.6 a hollow glass cylinder was positioned simulating a 4 mm diameter implant and the gingival component was recreated by using dedicated silicone. A Bass brushing technique was performed from the vestibular side in humid environment. During it, the penetration of the bristles between the gum and the implant was recorded by mean of an optic fibre fixed inside the cylinder. The protocol included 5 toothbrushes per group and 10 tests per toothbrush, for a total of 50 assessments for each of the two groups. A scale of 5 grades for bristle penetration was defined: grade 0 (× < 2 mm), grade 1 (2 ≤ × < 3 mm), grade 2 (3 ≤ × < 4 mm), grade 3 (4 ≤ × < 5 mm) and grade 4 (5 ≤ × < 8 mm). From the video recordings the highest value of penetration was identified for each test. RESULTS The tapered bristles showed an 8 times greater penetration capacity (p = 0.001) in respect to the cylindrical bristles (multilevel analysis). The percentage of tests reaching depths ≥3 mm was 86% for tapered group and 28% for the cylindrical group. CONCLUSION This preclinical study shows a clear and superior penetration capacity of the tapered bristles in respect to traditional cylindrical ones. For tapered bristles, a potentially greater hygienic efficacy around dental implants is suggested.

Abstract
BACKGROUND The microbial contamination of a respirator can be evaluated through a count of the number of bacteria living on a non-sterilized surface (bioburden). This preliminary study investigated the external contamination of two different FFP2s over time by studying the bioburden values in increasing exposure times. METHODS FFP2 respirators of two different brands were used during routine clinical settings and examined through the bioburden test; for each brand, three devices were tested at 8, 16, and 30 h. RESULTS No significant differences were observed between mask brands (p = 0.113). There were only significant CFU differences between each mask and its control (p = 0.027 and p = 0.004). CONCLUSIONS Both brands of respirators were found to be contaminated and this contamination increased with the increase in exposure time. Further studies are needed to investigate the exact amount of contamination that could be considered acceptable before discarding each used mask.

Abstract
Purpose The aim of this study was to compare the prevalence and bacterial load of 6 main periodontal pathogens between pairs of periodontal patients with and without type 2 diabetes mellitus. Porphyromonas gingivalis and Aggregatibacter actinomycetemcomitans genotypes were also investigated. Methods Twenty patients affected by chronic periodontitis and type 2 diabetes were retrospectively selected and matched to 20 patients without diabetes on the basis of the degree and severity of periodontal disease. Microbiological data of subgingival biofilms were analysed and compared for the examined pathogens: A. actinomycetemcomitans, P. gingivalis, Prevotella intermedia, Treponema denticola, Fusobacterium nucleatum, and Tannerella forsythia. Results The pairs were balanced in terms of demographic and clinical parameters, except for bleeding on probing and suppuration. In the microbiological test sites (4 for each patient), the mean probing pocket depth was 6.34±1.63 mm in patients with diabetes and 6.41±1.78 mm in patients without diabetes. No significant difference between pairs in the prevalence of P. gingivalis or the distribution of its genotypes was recorded. Patients with diabetes had a significantly greater amount of total bacterial load, P. gingivalis, T. denticola, T. forsythia, and F. nucleatum (P<0.05). Moreover, patients with diabetes had a higher number of sites with a greater cell count than patients without diabetes. When compared to the total bacterial load, only T. forsythia maintained its relative load in patients with diabetes (P=0.001). Conclusions This retrospective matched study supports the hypothesis that microbiological differences exist among periodontal patients with and without diabetes mellitus. Trial Registration ClinicalTrials.gov Identifier: NCT03786133

Abstract
Objective Recent SARS-COV2 pandemic put Healthcare System in severe overload. It is well demonstrated that malnutrition is related to worse outcomes in acute and chronic diseases. During this sanitary emergency the Clinical Nutrition Unit in Bologna developed an early nutrition protocol for hospital ad home COVID-19 patients. Methods and procedures Recently published recommendations regarding nutritional needs in COVID-19 patients and general Clinical Nutrition Guidelines were searched on PubMed. Results The hospital algorithm considered three different steps: oral feeding, enteral feeding and parenteral nutrition, recommending early nutrition therapy (within 24-48 hours of hospitalization). We arranged a modified oral "COVID diet" consisting in soft or creamy hypercaloric-hyperproteic meals in disposable packages . As far as artificial nutrition is concerned we chose hypercaloric, high-protein Oral Nutrition Supplements (ONS), enteral formulas and parenteral formulas, all enriched with EPA and DHA. Due to high micronutrients requirements each patient was recommended high-dose uniparenteral vitamin D and thiamine. For home COVID-19 patients screening using NRS-2003 was recommended: for those at low nutritional risk we provided general nutritional advice; for those at intermediate risk we suggested a dietitian consultation for personalized nutritional plan or ONS prescription. For those at high nutritional risk the nutritionist physician evaluation was suggested for disease-specific ONS or artificial nutrition prescription. All patients were suggested vitamin D 2000 IU / day and a multivitamin supplement. Conclusion During COVID-19 pandemic continuous clinical updating and adaptation to new clinical settings helped to develop an Early Nutrition Protocol for fast nutritional assessment and treatment in a large number of patients and emergency conditions.

Abstract
PURPOSE The aim of this preclinical study was to evaluate whether implant flossing could leave floss residues in three different implant-prosthetic conditions. MATERIALS AND METHODS Using an anatomical model, three different conditions were studied: correct connection between the implant and abutment and complete insertion of the implant threads into the plaster (control group); misfit of approximately 220 to 230 μm between the implant platform and abutment in the absence of any thread exposure (misfit group); partial exposure of implant threads but absence of misfit (thread group). Twenty-one microstructured tapered threaded implants were divided among the three groups. Each sample was subjected to a flossing procedure using spongy floss, standardized in terms of movement, frequency, time, and pressure. Subsequently, a stereomicroscope examination with a standardized magnification of 10× was performed in order to highlight the possible presence of floss residues on the implant surface. RESULTS No floss residue was ever detected for the control group. Both misfit and thread groups showed floss residues that were discernible in two different types: microfilaments and amorphous particles. Statistical analysis showed a significant difference for the presence of floss remnants between the control group and the other two experimental groups (P = .005). No difference was observed between the misfit and thread groups. CONCLUSION This study shows that exposed threads and misfit can induce the release of floss residues during maintenance procedures.

Abstract
AIMS The evaluation of the patient with chest pain in the emergency department is one of the most common situations that the doctor has to face. The diagnostic procedure supposes an observation period of at least 6-12 hours, a well organized medical facilities and the identification of all SCA cases to reduce inappropriate admission. MATERIALS AND METHODS In our study we have estimated the utility of the marker assay that is associated to the use of risk scores (TIMI and GRACE risk score) to obtain indication about the most appropriate assistance level. In particular, we used the assay of necrosis markers to highlight the damage along with the assay of natriuretic peptides for their role in the diagnosis and in the monitoring of the patients with cardiac damage. RESULTS Also PCR has an important role such as marker of plaque stability and of inflammation. These markers associated to the necrosis markers could give important clinical information of independent nature. DISCUSSION The sensibility of laboratory markers, without important necrosis, is low and it is not possible to exclude in a few time a SCA There is now an alternative strategy: a precocious risk stratification. Using clinical criteria it is possible to do a first evaluation of the probability of SCA and the complications.

Abstract
In Italy one of the most common cause of access to the Emergency Departments is not traumatic chest pain, representing from the 6% to 10% of all the diagnoses. Admissions to the Emergency Department (DEA) of Policlinico Umberto I of Rome for non-traumatic chest pain, occurred between 2000 and 2008, were analyzed in this study. Out of 26,8910 admissions to the medical emergency room (PS), 21,088 (7.84%) were due to non-traumatic or precordial chest pain. Of these, 2881 (14%) patients had a diagnosis of myocardial infarction STEMI, NSTEMI and IA and 18,207 (86%) had a diagnosis of atypical chest pain, representing respectively 1.07% and 6.77% of all admissions to PS. About 27.62% of patients with atypical chest pain were discharged from the PS, 33.27% were hospitalized, 36.73% refused hospitalization, 1.68% were transferred elsewhere, and 0.7% did not uptake the visit. 85% of patients with myocardial infarction STEMI, NSTEMI and IA were hospitalized, 3.75% refused hospitalization, 8.82% were transferred elsewhere, and 1.71% died in the PS. Hospitalizations resulted often in unjustified and protracted length of hospital stays for clinical investigations, with negative repercussions for patients and costs. In the last years, the number of inappropriate hospitalizations progressively increased, partly as consequence of recourse to the court aiming at defining legal responsibility of the health board.Since avoiding inappropriate hospital admissions is an essential requirement for containing healthcare costs and improving the health service, Chest Pain Unit has been established. Its responsibility is to recognize and promptly treat patients with chest pain and acute coronary syndrome. As well, it is responsible to quickly discharge patients with chest pain at low and intermediate risk of acute coronary insufficiency, after careful clinical assessment lasting 24-36 hours.

Abstract
BACKGROUND Weight gain is a common side effect observed in women undergoing adjuvant chemotherapy for breast cancer. Among possible causes a direct effect of chemotherapy on metabolism has been proposed. Body composition variations after adjuvant chemotherapy suggest the occurrence of sarcopenic obesity, possibly due to ovarian failure. We investigated acute and chronic effects of adjuvant chemotherapy on body weight, resting energy expenditure (REE) and plasma catecholamines in a group of menopausal women. PATIENTS AND METHODS Thirty menopausal women with stage I-II breast cancer were recruited for the study. We measured REE and respiratory quotient (RQ) and body composition at the beginning and after 3 and 6 months of adjuvant cyclophosphomide, methotrexate, and 5-fluorouracil (CMF). REE, RQ, and plasma catecholamines were assessed before and after each chemotherapy session. At each session food intake was also assessed in all patients, by a food diary. Seven patients out of the group of 30 were also evaluated after a placebo infusion (saline). RESULTS A significant weight gain was observed in all women (70.5 +/- 3 v.s. 67.7 +/- 3 kg, p < 0.001), with increase in both fat-free mass (FFM) (45.2 +/- 1.5 v.s. 43.6 +/- 1.3 kg, p < 0.001) and fat-mass (FM) (25.3 +/- 1.7 v.s. 24.1 +/- 1.8 kg, p < 0.005). A decrease in REE and RQ was observed both during CMF and placebo infusion (p < 0.05). During acute CMF and placebo infusion a reduction of plasma levels of noradrenaline was observed at the first and last session. REE increased progressively during the study period. CONCLUSIONS CMF therapy apparently has no effect on REE either acutely or during a 6-month-period; the increased REE observed in the long-term is likely due to the concomitant increase in FFM. The lack of evidence of sarcopenic obesity, at variance with previous literature, is likely due to different patient selection.

Abstract
We evaluated neuropeptide Y (NPY) and galanin (GAL) immunoreactivity (IR) and mRNA in the paraventricular and arcuate nucleus, respectively, in rats that became overweight (Ov) or not (NOv) when fed a cafeteria diet. After 2 months of diet, NOv rats showed a significant increase in NPY IR, whereas Ov rats showed a significant increase in GAL mRNA levels. None of these changes was present in rats overfed for 6.5 months. These differential changes in hypothalamic GAL and NPY transmissions may contribute to the different susceptibility of the two rat subpopulations to the weight-promoting effects of the hypercaloric diet.
