Abstract
Increasing evidence support the association between the oral microbiome and human systemic diseases. This association may be attributed to the ability of many oral microbes to influence the inflammatory microenvironment. Herein, we focused our attention on the bidirectional relationship between periodontitis and type 2 diabetes using high-resolution whole metagenomic shotgun analysis to explore the composition and functional profile of the subgingival microbiome in diabetics and non-diabetics subjects with different periodontal conditions. In the present study, the abundance of metabolic pathways encoded by oral microbes was reconstructed from the metagenome, and we identified a set of dysregulated metabolic pathways significantly enriched in the periodontitis and/or diabetic patients. These pathways were mainly involved in branched and aromatic amino acids metabolism, fatty acid biosynthesis and adipocytokine signaling pathways, ferroptosis and iron homeostasis, nucleotide metabolism, and finally in the peptidoglycan and lipopolysaccharides synthesis. Overall, the results of the present study provide evidence in favor of the hypothesis that during the primary inflammatory challenge, regardless of whether it is induced by periodontitis or diabetes, endotoxemia and/or the release of inflammatory cytokines cause a change in precursor and/or in circulating innate immune cells. Dysbiosis and inflammation, also via oral-gut microbiome axis or adipose tissue, reduce the efficacy of the host immune response, while fueling inflammation and can induce that metabolic/epigenetic reprogramming of chromatin accessibility of genes related to the immune response. Moreover, the presence of an enhanced ferroptosis and an imbalance in purine/pyrimidine metabolism provides new insights into the role of ferroptotic death in this comorbidity.

Abstract
PURPOSE To comparatively evaluate transcrestal sinus floor elevation (tSFE) and lateral sinus floor elevation (lSFE) at sites with different residual bone heights (RBHs). MATERIALS AND METHODS A re-analysis of data from a parallel-arm, randomized trial comparatively evaluating tSFE and lSFE was performed. Within each RBH interval (< 4 mm or ≥ 4 mm), tSFE and lSFE groups were compared for chair time, surgery-related costs, morbidity, and radiographic parameters (including the proportion of the implant surface in direct contact with the radiopaque area [totCON%]). RESULTS The intention-to-treat (ITT) population consisted of 29 and 28 patients in the tSFE and lSFE groups, respectively. Irrespective of RBH, both tSFE and lSFE lead to a median totCON% of 100%. At sites with RBH < 4 mm, pain severity was significantly higher at days 0 and 1 in the tSFE group, with no intergroup difference in the dose of analgesics. LSFE was associated with a significantly higher frequency of bruising and greater cost. At sites with RBH ≥ 4 mm, a significantly lower frequency of postoperative signs/symptoms, less chair time, and lower costs were observed in the tSFE group. CONCLUSIONS The selection of tSFE or lSFE within the investigated RBH intervals seems to be supported by differences in chair time, costs, and morbidity between the two techniques. At sites with RBH < 4 mm, clinicians preferring tSFE should encourage the administration of analgesics according to a predefined plan in the early postoperative phase. At sites with RBH ≥ 4 mm, tSFE should be preferred to lSFE due to reduced chair time, costs, and morbidity.

Abstract
BACKGROUND Recently, a composite outcome measure (COM) was proposed to describe the short-term results of periodontal regenerative treatment. The present retrospective study aimed at evaluating the prognostic value of COM on clinical attachment level (CAL) change over a 4-year period of supportive periodontal care (SPC). METHODS Seventy-four intraosseous defects in 59 patients were evaluated at 6 months and 4 years following regenerative treatment. Based on 6-month CAL change and probing depth (PD), defects were classified as: COM1 (CAL gain ≥3 mm, PD ≤4 mm); COM2 (CAL gain <3 mm, PD ≤4 mm); COM3 (CAL gain ≥3 mm, PD >4 mm); or COM4 (CAL gain <3 mm, PD >4 mm). COM groups were compared for "stability" (i.e., CAL gain, no change in CAL or CAL loss <1 mm) at 4 years. Also, groups were compared for mean change in PD and CAL, need for surgical retreatment, and tooth survival. RESULTS At 4 years, the proportion of stable defects in COM1, COM2, COM3, and COM4 group was 69.2%, 75%, 50%, and 28.6%, respectively, with a substantially higher probability for a defect to show stability for COM1, COM2, and COM3 compared with COM4 (odds ratio 4.6, 9.1, and 2.4, respectively). Although higher prevalence of surgical reinterventions and lower tooth survival were observed in COM4, no significant differences were detected among COM groups. CONCLUSIONS COM may be of value in predicting CAL change at sites undergoing SPC following periodontal regenerative surgery. Studies on larger cohorts, however, are needed to substantiate the present findings.

Abstract
OBJECTIVES To comparatively evaluate the 6-year outcomes of transcrestal and lateral sinus floor elevation (tSFE and lSFE, respectively). METHODS The 54 patients representing the per-protocol population of a randomized trial comparing implant placement with simultaneous tSFE versus lSFE at sites with a residual bone height of 3-6 mm were invited to participate in the 6-year follow-up visit. Study assessments included: peri-implant marginal bone level at the mesial (mMBL) and distal (dMBL) aspects of the implant, proportion of the entire implant surface in direct contact with the radiopaque area (totCON%), probing depth, bleeding on probing, suppuration on probing, and modified plaque index. Also, the conditions of the peri-implant tissues at 6-year visit were diagnosed according to the case definitions of peri-implant health, mucositis, and peri-implantitis from the 2017 World Workshop. RESULTS Forty-three patients (21 treated with tSFE and 22 treated with lSFE) participated in the 6-year visit. Implant survival was 100%. At 6 years, totCON% was 96% (IR: 88%-100%) in tSFE group and 100% (IR: 98%-100%) in lSFE group (p = .036). No significant intergroup difference in patient distribution according to the diagnosis of peri-implant health/disease was observed. Median dMBL was 0.3 mm in tSFE group and 0 mm in lSFE group (p = .024). CONCLUSIONS At 6 years following placement concomitantly with tSFE and lSFE, implants showed similar conditions of peri-implant health. Peri-implant bone support was high in both groups and was slightly but significantly lower in tSFE group.

Abstract
Currently, periodontal risk assessment finds application at first visit (to identify individuals at high risk of either disease incidence, if still healthy, or disease progression, if already diseased) as well as at patient monitoring after active treatment and enrolment in a supportive periodontal care program. Although the current case definition of periodontitis embeds a prognostic determination (ie, periodontitis grade) that showed a predictive value for periodontitis-related tooth loss, some limitations of periodontitis grade call for the implementation of different risk assessment tools in clinical practice. For some of these, significantly higher accuracy in predicting tooth loss during supportive periodontal care was reported compared with periodontitis grade. Validated periodontal risk assessment tools may be functional to obtain greater adherence to the suggested preventive and treatment protocols, improve oral hygiene performance, and tailor supportive periodontal care. Interestingly, periodontal risk can also be informative of the risk of peri-implantitis in patients programmed for implant placement or rehabilitated with dental implants. A critical appraisal on the rationale behind risk assessment and the balance between the advantages and limitations of exercising risk assessment in periodontology is presented.

Abstract
BACKGROUND A recent systematic review failed to identify one approach for alveolar ridge preservation with superior outcomes. The present case series aimed to evaluate the dimensional changes of sites undergoing Biologically-oriented Alveolar Ridge Preservation (BARP). METHODS The sockets were filled with a collagen sponge up to 4-5 mm from the most coronal extensions of the crest. Xenograft particles were placed to fill the coronal part. In cases with a compromised buccal/lingual bone, an additional collagen sponge was interposed between the residual cortical bone plate and the mucoperiosteal flap. A collagen sponge was placed to cover the graft. RESULTS The study population consisted in 10 extraction sites. Mean change in bone width and vertical ridge position as observed from BARP to re-entry for implant placement were 1.3 mm (14.4%) and 0.6 mm, respectively. The mean distance between buccal and lingual flap healing by secondary intention shifted from 4.9 mm immediately after BARP to 1.8 mm at 2 weeks. No marked differences in the dimensional changes of alveolar ridge were observed between sites with intact or deficient buccal bone plate. All implants were successfully loaded at 2-3 months after placement. In one case, bone augmentation was required. CONCLUSIONS The stratification of materials proposed in BARP-technique and the additional use of a resorbable device to stabilize graft particles at the buccal aspect provided the conditions for maintaining the ridge dimensions following tooth extraction comparable to the other technique of ARP, restricting the use of graft material to the most coronal portion of the socket.

Abstract
The presence of a peri-implant bone dehiscence (BD) or fenestration (BF) is a common finding after implant placement in a crest with a reduced bucco-lingual bone dimension. The presence of a residual BD is associated with a relevant incidence of peri-implant biological complications over time. Guided bone regeneration (GBR), performed at implant placement, is the most validated treatment to correct a BD. In the present systematic review, the evidence evaluating factors which could reduce the invasiveness of a GBR procedure with respect to patient-reported outcomes, intra- and post- surgical complications, was summarized. Factors included were: technical aspects, regenerative materials for GBR, and peri- and post-operative pharmacological regimens. The available evidence seems to indicate that the use of membrane fixation and flap passivation by means of a double flap incision technique may reduce the incidence of post-surgical complications. When feasible, the coronal advancement of the lingual flap is suggested. The use of a non-cross linked resorbable membrane positively impacts on patient discomfort. The adjunctive use of autogenous bone to a xenograft seems not to improve BD correction, but could increase patient discomfort. Systemic antibiotic administration after a GBR procedure does not seem to be justified in systemically healthy patients.

Abstract
The modern approach to regenerative treatment of periodontal intraosseous defects should aim at maximizing the clinical outcomes while minimizing the invasiveness (pain, complications, aesthetic impairment, chair time, and costs) of the procedure. The present systematic review evaluated the effect of flap design, regenerative technology, and perioperative and postoperative adjunctive protocols on invasiveness. Overall, the results of the 13 included trials indicate that: (a) the elevation of a single (buccal or lingual) flap positively influences the intensity of postoperative pain and improves the quality of early wound healing compared with double flaps; (b) while the adjunctive use of a membrane is associated with significantly longer surgery-related chair time and higher postoperative pain, the adjunctive use of enamel matrix derivative at sites receiving a graft significantly reduces postoperative pain; also, graft materials showed no significant impact on invasiveness; (c) open flap debridement performed through the elevation of a single flap may lead to substantial clinical improvements of the lesion with reduced surgery-related chair time and costs, thus representing a promising alternative to regenerative treatment. However, for such an approach, a histological evaluation of the nature of the reconstructed tissues is still lacking, and the presurgery conditions (eg, probing depth, defect severity, and defect morphology), which may benefit in terms of invasiveness, have not yet been defined; and (d) intraoperative and postoperative low-level laser biostimulation of the defect site may favorably modulate the postoperative course.

Abstract
In the attempt to reduce the invasiveness of a transcrestal sinus floor elevation procedure, different aspects must be considered; that is, the minimization of intra- and postsurgery morbidity, the reduction of treatment time, and the simplification/elimination of the reconstructive technology. Within this context, a systematic literature search was performed for controlled clinical trials evaluating the impact of one or more of these aspects on transcrestal sinus floor elevation invasiveness. Nineteen articles (15 studies) were included. Overall, the results confirmed that transcrestal sinus floor elevation is a minimally invasive and effective option for bone augmentation in the edentulous, atrophic posterior maxilla. By using powered instruments rather than manual osteotomes and hand mallet, the invasiveness of transcrestal sinus floor elevation can be further reduced without affecting its clinical effectiveness. To impact effectively on morbidity, the key elements to consider when selecting instruments for transcrestal sinus floor elevation are (a) their availability as a standardized sequence, to be adapted on predetermined residual bone height, and (b) the possibility to control pressure (eg, with screwable osteotomes) and/or instrument excursion (eg, with stop devices) to fracture the maxillary sinus floor. Among powered instruments, a standardized sequence of drills incorporating a trephine drill seem to be particularly indicated, due to reduced chair time, high tolerability for the patient, and the possibility to isolate a bone core to implement histomorphometric outcomes. At molar extraction sites with an interradicular septum characterized by a height of at least 4 mm, immediate transcrestal sinus floor elevation and implant placement can be considered a valid option to shorten treatment time.

Abstract
Purpose The aim of the present systematic review was to evaluate the effect of different lateral bone augmentation (LBA) procedures on the complete correction of a peri‐implant bone dehiscence (BD) or fenestration (BF) from implant placement to implant surgical uncovering. Methods Electronic (Medline, Scopus, and Cochrane databases) and hand literature searches were performed for studies including at least one treatment arm where any LBA had been applied to correct a BD/BF at implant placement (T0). Studies where BD/BF was left untreated were also retrieved as negative control. Data from 24 selected articles were used to perform a network meta‐analysis. Based on the proportion of nonresolved BD/BF at implant surgical uncovering (T1), a hierarchy of LBA procedures, and was determined. Spontaneous healing (i.e., exposed implant surface covered by a full‐thickness flap; SELF) was also included in the hierarchy. Resorbable membrane + bone graft (RM + BG) was used as reference group. An analysis on the effect of nonhuman (NHBS) vs human (HBS) derived bone substitutes was also performed. NHBS was used as the reference group. Results No statistically significant differences were found among treatments for the proportion of nonresolved BD/BF. SELF performed substantially worse compared to RM + BG (OR: 5.78 × 10, CI: 4.83 × 10 – 1.3 × 1086). Treatment based on a combination of a graft material and membrane/periosteum appeared to perform slightly better than treatments using graft material or membrane alone. NHBS appeared to perform better than HBS. SELF had the worst effect among all treatments for both BD/BF height reduction (BDH) and BD/BF width reduction (BDW). Nonresorbable membrane (NRM) and patient's own periosteum (PERI) + BG showed greater increases in buccal bone thickness than RM + BG. Conclusion Reconstructive treatment (including use of graft alone, membrane alone, or combinations of grafts and either membrane or patient's own periosteum) of a BD/BF at implant placement favorably and significantly impacts on the probability to obtain complete correction of the BD/BF at implant uncovering when compared to full‐thickness flap repositioning on the BD/BF. When using a bone substitute, a nonhuman derived one may be suggested.

Abstract
AIM To assess the efficacy of a commercially available adjunctive phototherapy protocol ("Perio-1") in treatment of periodontitis. MATERIALS AND METHODS In an examiner-blind, randomized, controlled, split-mouth, multicentre study, 60 periodontitis patients received root surface debridement (RSD) in sextants either alone (control sextants) or with the adjunctive phototherapy protocol (test sextants). Re-evaluation was performed at 6, 12 and 24 weeks. RESULTS No statistically significant differences in mean (± standard deviation) clinical attachment level (CAL) change from baseline to week 24 were observed between test (-1.00 ± 1.16 mm) and control sextants (-0.87 ± 0.79 mm) at sites with probing pocket depths (PPDs) ≥5 mm ("deep sites") at baseline (p = .212). Comparisons between test and control sextants for all other parameters (CAL change at all sites, PPD change at deep sites/all sites, bleeding on probing, plaque scores), and for all change intervals, failed to identify any statistically significant differences. CONCLUSIONS The phototherapy protocol did not provide any additional clinical benefits over those achieved by RSD alone. (German Clinical Trials Register DRKS00011229).

Abstract
AIM to comparatively evaluate costs and specific aspects of oral-health related quality of life (OhRQoL) related to the period between the surgery phase of transcrestal and lateral sinus floor elevation (tSFE and lSFE, respectively) and 6 months after delivery of implant-supported prosthesis. METHODS A bi-center, parallel-arm, randomized trial comparatively evaluating tSFE and lSFE when applied concomitantly with implant placement was conducted. At 6 months after prosthesis delivery, data on cost-associated items related to the post-surgery period and selected aspects of OhRQoL were collected. RESULTS Analyses of costs and quality of life was conducted on 56 patients (tSFE: 28; lSFE: 28) and 54 patients (tSFE: 26; lSFE: 28), respectively. Significantly lower dose of anesthetic (2 vs 3 vials), amount of xenograft (420 mg vs 1975 mg), and duration of surgery (54' vs 86') were observed for tSFE compared to lSFE. No significant differences in the number of additional surgical sessions, postoperative exams, specialist consultations and drug consumption were found between groups. In a limited fraction of patients in both groups, improvements were observed for pain (tSFE: 3.8%; lSFE: 7.4%), comfort in eating any food (tSFE: 11.5%; lSFE: 3.6%), self-consciousness (tSFE: 19.2%; lSFE: 14.3%), and satisfaction about life (tSFE: 19.2%; lSFE: 10.7%). CONCLUSIONS The surgery phase of maxillary sinus floor elevation is characterized by more favorable cost-associated items for tSFE compared to lSFE. Differently, tSFE and lSFE do not differ for either costs related to the post-surgery phases or impact of the implant-supported rehabilitation on specific aspects of OhRQoL.

Abstract
Aim To comparatively evaluate the clinical effectiveness of the single flap approach (SFA) with and without enamel matrix derivative (EMD) in the treatment of supraosseous defects (SDs) associated with deep pockets. Materials and methods Twenty patients, each contributing one SD associated with a deep (≥ 6 mm) pocket and treated with buccal SFA either alone (SFA group; n = 10) or in combination with EMD (SFA+EMD group; n =10), were retrospectively selected. Clinical parameters (probing depth, PD; clinical attachment level, CAL; gingival recession, REC) had been assessed at pre-surgery and 12 months post-surgery. Results Complete wound closure was observed in 70% and 80% of defects treated with SFA and SFA+EMD, respectively. Treatments resulted in a significant PD reduction of 3.1±1.0 mm (p=0.005). In SFA+EMD group, 100% of closed pockets was obtained, while 90% of closed pockets was observed in SFA group. Both treatments resulted in a significant CAL gain of 2.1±0.9 mm and 1.9±1.7 mm in SFA and SFA+EMD group, respectively (p= 0.465). In both groups, REC significantly increased 1.0±1.1 mm in SFA group and 1.1±1.1 mm in SFA+EMD group (p= 0.722). Conclusions Within their limits, the findings of present study suggest that SFA may represent a valuable option for the surgical treatment of SDs associated with deep pockets. EMD did not result in a significant clinical benefit to the procedure. Clinical relevance SFA may represent a valuable option in obtaining pocket closure when treating SDs associated with deep residual pockets.

Abstract
The study presents results of toxicological analysis performed on seized material in Neapolitan area in the period from 2013 to 2018. A constancy in THC and heroin percentages is evidenced (%THC ~10% and ~11.5% for marijuana and hashish; heroine: 20-24%), with mean values exceeding the European data. Data on cocaine revealed a constant increment of active principle percentage over the studied period (from 40% in 2013 to ~65% in 2018), with peak of 70% in 2017; also, number of samples exceeding the mean value increased over years. Active principles contents resulted higher than the ones reported in other Italian area ever the same period; marijuana was prevalent on hashish, confirming an Italian trend different from other European countries. A map of the Campania region evidenced two main "storage" districts, one corresponding to the city center and the second located in the northern part. If compared with literature data on the presence of local mafia, these areas are perfectly superimposable to those with the highest risk of homicides, thus confirming the degree of radicalization of local organizations and the relative weight of proceeds from drugs sale. Moreover, such radicalization within the territory seems to be the main reason of the absence of new psychoactive substances among the seized material.

Abstract
INTRODUCTION The efficacy of surgical regenerative procedures to treat peri-implantitis lesions has been extensively reviewed. Regenerative treatment showed a variable rate of success, in terms of pocket reduction, gain in bone support, and elimination of signs of infection/inflammation. The aim of the present case report is to illustrate the use of the sub-periosteal peri-implant augmented layer (SPAL) technique to correct peri-implantitis defects CASE PRESENTATION: Surgical treatment of three class Ib and one class Ic peri-implantitis lesions in three patients was performed by means of the SPAL technique. A partial-thickness flap was elevated, leaving the periosteal layer on the buccal cortical bone plate. The periosteal layer was in turn elevated to create a pouch, which was used to stabilize a bovine-derived xenograft (deproteinized bovine bone mineral) at the peri-implant buccal bone defect. No barrier membrane was used. In case of insufficient dimensions of peri-implant mucosa, a connective tissue graft (CTG) was buccally positioned at the most coronal portion of the implant. Treatment resulted in substantial reconstruction of peri-implant support associated with reduced probing depth and absence of inflammation. CONCLUSIONS SPAL technique with or without additional CTG may be a suitable option to obtain clinical remission of peri-implantitis defects associated with buccal bone dehiscence.

Abstract
INTRODUCTION A recent systematic review failed to identify one approach for alveolar ridge preservation (ARP) with superior outcomes compared with the others. The present case report presents a novel, simplified technique for ARP, namely the Biologically-oriented Alveolar Ridge Preservation (BARP), based on socket grafting and sealing. CASE PRESENTATION After extraction of tooth #19, the socket was filled with a collagen sponge up to 4-5 mm from the most coronal extension of the bone crest (deep collagen layer). A bovine-derived xenograft was placed on top of the collagen sponge to fill the coronal part of the socket (graft layer). Socket sealing was then performed by placing a collagen sponge over the exposed portion of the graft (superficial collagen layer), and the wound healed by secondary intention. At implant insertion (4 months after ARP), limited reduction in bone width and no vertical change in ridge height were observed. Histological analysis of a biopsy specimen retrieved during implant site preparation showed a gradient ranging from interconnected trabeculae of mature, lamellar bone in the apical portion to cancellous bone incorporating a modest number of remodeled graft granules in the central portion. In the coronal portion, non-mineralized tissue with sparse isles of newly formed cancellous bone and residual graft granules was found. CONCLUSION The present case report indicates that BARP might provide ideal conditions for preserving the pre-existing alveolar ridge dimensions following tooth extraction while restricting any potential interference of the graft biomaterial with bone healing dynamics to the coronal part of the socket.

Abstract
OBJECTIVES To assess peri-implant tissue conditions on the short term in patients receiving the Sub-periosteal Peri-implant Augmented Layer (SPAL) technique and in patients with adequate thickness (≥2 mm) of the peri-implant buccal bone plate (PBBP) at placement. METHODS Patients where either a dehiscence defect or thin PBBP at implant placement was corrected by SPAL technique (SPALdehiscence and SPALthin groups, respectively) and patients presenting a residual PBBP thickness ≥2 mm at implant placement (control group) were retrospectively selected. The number of peri-implant sites positive to bleeding on probing (BoP) at 6 months following prosthetic loading was the primary outcome. Also, height of keratinized mucosa, marginal soft tissue level, Plaque Index, peri-implant probing depth, suppuration on probing, and interproximal radiographic bone level (RBL) were evaluated. RESULTS Thirty-four patients (11 in the SPALdehiscence group, 11 in the SPALthin group, and 12 in the control group) were included. In each SPAL group, 10 patients (90.9%) showed peri-implant tissue thickness ≥2 mm at the most coronal portion of the implant at uncovering. The prevalence (number) of BoP-positive sites was 2, 1, and 0 in the SPALdehiscence , SPALthin , and control groups, respectively. RBL amounted to 0.3 mm in the SPALdehiscence group, 0.2 mm in the SPALthin group, and 0 mm in the control group. CONCLUSION After 6 months of prosthetic loading, patients treated with SPAL technique show limited peri-implant mucosal inflammation in association with shallow PD and adequate KM. At implants receiving SPAL technique, however, interproximal RBL was found apical to its ideal position.

Abstract
Tumor-associated macrophages (TAM) are regulators of extracellular matrix (ECM) remodeling and metastatic progression, the main cause of cancer-associated death. We found that disabled homolog 2 mitogen-responsive phosphoprotein (DAB2) is highly expressed in tumor-infiltrating TAMs and that its genetic ablation significantly impairs lung metastasis formation. DAB2-expressing TAMs, mainly localized along the tumor-invasive front, participate in integrin recycling, ECM remodeling, and directional migration in a tridimensional matrix. DAB2+ macrophages escort the invasive dissemination of cancer cells by a mechanosensing pathway requiring the transcription factor YAP. In human lobular breast and gastric carcinomas, DAB2+ TAMs correlated with a poor clinical outcome, identifying DAB2 as potential prognostic biomarker for stratification of patients with cancer. DAB2 is therefore central for the prometastatic activity of TAMs. SIGNIFICANCE: DAB2 expression in macrophages is essential for metastasis formation but not primary tumor growth. Mechanosensing cues, activating the complex YAP-TAZ, regulate DAB2 in macrophages, which in turn controls integrin recycling and ECM remodeling in 3-D tissue matrix. The presence of DAB2+ TAMs in patients with cancer correlates with worse prognosis.This article is highlighted in the In This Issue feature, p. 1611.

Abstract
Objective: To systematically review the literature addressing the focused question: What is the effectiveness of different surgical and nonsurgical procedures combined with enamel matrix derivative (EMD) on clinical, radiographic, and patient-centered outcomes in intraosseous defects? Methods: Electronic (Medline, Scopus, and Cochrane databases) and hand literature searches were performed for studies including at least 1 treatment arm where EMD had been applied according to 1 of the following procedures: modified Widman flap; papilla preservation variants (PPVs), including papilla preservation technique, modified papilla preservation technique, and simplified papilla preservation technique; minimally invasive variants, including minimally invasive surgical approach and minimally invasive surgical technique; single-flap variants (SFVs), including single-flap approach and modified minimally invasive surgical technique; or nonsurgical application (flapless approach). Data from 42 selected articles were used to perform a network meta-analysis, and a hierarchy of surgical and nonsurgical applications of EMD was built separately for EMD and EMD + graft based on 6- to 12-mo clinical and radiographic outcomes. Results: Among surgical approaches, EMD was associated with best regenerative outcomes when applied through SFVs, with a mean clinical attachment level gain of 3.93 mm and a reduction in the intrabony component of the defect of 3.35 mm. For EMD + graft, limited differences in regenerative outcomes were observed among surgical procedures. PPVs were associated with the highest residual probing depth for EMD (4.08 mm) and EMD + graft (4.32 mm). Conclusions: In the treatment of periodontal intraosseous defects, 1) SFVs appear to optimize the regenerative outcomes of EMD; 2) substantial regenerative outcomes can be obtained with SFVs and conservative double flaps (i.e., PPVs and minimally invasive variants) when EMD is combined with a graft; and 3) residual probing depth was higher following PPVs for EMD and EMD + graft. Knowledge Transfer Statement: The results of the present systematic review and meta-analysis can be used by clinicians to identify the most effective surgical or nonsurgical procedure to treat an intraosseous defect with EMD or EMD + graft. The main findings indicate that when EMD application is indicated, surgical access based on a single flap seems the most appropriate to optimize clinical outcomes. The application of EMD + graft can be effectively combined with single flaps and conservative double flaps.

Abstract
Hair, larvae and cardiac muscle, the only biological samples present on a skeletonized human body found in a rural area, were used for forensic toxicological analyses in order to determine possible causes of death. Since no information about the victim or the circumstances of death was available (except for the place where the corpse was found, known to be a gathering place for drug addicts), the first approach for the analysis of non-conventional matrices involved the screening of different classes of active principles, using a chemiluminescence-based screening assay designed for whole blood. The immunoassay test results showed positivity to amphetamines, cocaine and opiates on water/methanol extract from cardiac tissue, larvae and hair samples. Gas chromatography-mass spectrometry (GC/MS) analyses confirmed the immunoassay results, except for amphetamines. The minimal sample preparation (hydration and extraction in an ultrasonic bath), the reduced sample volume required for the analyses, together with the correctness of results as confirmed by GC/MS, showed the suitability of the screening test for forensic applications on non-conventional matrices. Quantitative analyses in GC/MS allowed the cause of death to be ascertained on the basis of the ratio between parent drugs and metabolites.

Abstract
The present study was performed to evaluate the impact of smoking status on 6-month clinical outcomes of a regenerative procedure based on enamel matrix derivative and deproteinized bovine bone mineral in the treatment of intraosseous defects accessed with buccal single flap approach. A total of 22 defects were selected in smoking (n = 11) and nonsmoking (n = 11) patients. Regenerative treatment resulted in similar clinical attachment level (CAL) gain in both smokers and nonsmokers. A trend toward lower 6-month CAL gain and probing depth reduction was observed in patients smoking 11 to 20 cigarettes per day compared to those smoking 1 to 10 cigarettes per day.

Abstract
OBJECTIVES To evaluate the postsurgery gingival healing as well as plaque, gingival inflammation and staining levels following the use of a 0.2% chlorhexidine (CHX) solution with or without antidiscoloration system (ADS) and 0.2% hyaluronic acid (HA). METHODS Patients undergoing flap surgery at sites with an intact or reduced but healthy periodontium participated in a parallel-arm RCT. After surgery, patients used the assigned mouthrinse (CHX + HA + ADS or CHX) for 21 days. At days 7 and 21, the healing process was evaluated at experimental teeth using a composite index, namely the Gingival Healing Index (GHI). GHI score was obtained as the sum of the scores related to the severity of wound dehiscence (score 1-3) and the profile of the buccal and oral aspects of the papilla (score 1-3). Therefore, GHI ranged from 2 (worst quality of healing) to 6 (optimal quality of healing). Plaque Index (PlI), Gingival Index (GI), angulated bleeding score (AngBS), and tooth and tongue staining were also assessed. RESULTS In both groups, GHI assumed values of 5 or 6 at both days 7 and 21 in ≥50% of patients, and low median values of PlI, GI, AngBS and staining were observed during the 21-day period. Except for a significantly lower GI in CHX group at day 7, no other significant intergroup differences were found. CONCLUSIONS Postsurgery plaque control based on either CHX or CHX + HA + ADS mouthrinses results in optimal plaque control and quality of early gingival healing along with limited tooth and tongue staining.

Abstract
Gyroscopes IN GEneral Relativity (GINGER) is a proposed experiment with the aim of measuring in a ground laboratory the gravitoelectric and gravitomagnetic effects foreseen by general relativity through an array of ring laser gyroscopes. GINGERINO is a square ring-laser prototype that has been built to investigate the level of noise inside the Gran Sasso underground laboratory. GINGERINO has shown the advantage of the underground location. Now it provides suitable data for geophysics and seismology. Since May 2017, it has continuously acquired data. The analysis of the first 90 days shows that the duty cycle is higher than 95%, and the quantum shot noise limit is of the order of 10-10(rad/s)/Hz. It is located in a seismically active area, and it recorded part of the central Italy earthquakes. Its high sensitivity in the frequency band of fraction of hertz makes it suitable for seismology studies. The main purpose of the present analysis is to investigate the long-term response of the apparatus. Simple and fast routines to suppress the disturbances coming from the laser have been developed. The Allan deviation of the raw data reaches some 10-6 after about 106 s of integration time, while the processed data show an improvement of 1 order of magnitude. Disturbances at the daily time scale are present in the processed data, and the expected signal induced by polar motion and solid Earth tides is covered by those disturbances.

Abstract
Maternal depression represents an important social/environmental factor in early childhood; however, its effect on children's motor development may vary depending on the role of infants' dispositional variables. The objective of this study is to investigate the effect of the interaction between maternal depressive symptoms in the first two years of a child's life and the child's temperamental negative emotionality on motor development during this time. Using a cross-sectional study, we assessed 272 infants aged 0 to 24 months old and their mothers. We measured the following variables: maternal depression, infant's negative emotionality, and motor development. A three-way interaction effect highlights that negative emotionality in infants and maternal depression together affect children's overall motor growth trajectory. Infants with low negative emotionality display no effect of maternal depression on motor development. Conversely, infants with high negative emotionality seem to be more susceptible to the effect of maternal depression. Specifically, high maternal depression tends to foster the negative effect of infant's negativity on motor development across time, albeit not significantly. Finally, the absence of maternal depression significantly buffers negative temperament in infants. Findings highlighted the importance of integrating different perspectives when describing early motor growth. In fact, only when considering the interdependence of potential predictors their effect on the motor growth significantly emerges. Screening for early temperamental vulnerability might help in tailoring interventions to prevent maternal depression from affecting infants' motor development.

Abstract
Background: The Childhood Attachment and Relational Trauma Screen (CARTS) is a computer-administered survey designed to assess retrospectively the socio-ecological context in which instances of child abuse may have occurred. To date, studies supporting the validity of the CARTS have only been undertaken in English-speaking North American populations. Validation projects in other countries and cross-cultural comparisons are therefore warranted. Objective: Develop and preliminarily evaluate the psychometric properties of an Italian version of the CARTS on college students and compare such observations to data acquired from Canadian students. Method: Seventy-nine undergraduate students from the University of Padua (Italy) completed an Italian translation of the CARTS as well as measures of childhood experiences, mental health and attachment, responses to which were compared to those obtained in 288 Canadian students who completed the CARTS in English. Results: Internal consistency and convergent validity with the Childhood Trauma Questionnaire and Parental Bonding Instrument were found to be acceptable for the Italian translation. Within the Italian sample, correlation analyses suggested that CARTS Mother ratings referring to attachment and abuse were associated with romantic attachment, whereas CARTS Father ratings were significantly correlated to PTSD symptoms and other symptoms of psychopathology-distress. Significant differences between Italian and Canadian students across the relationship types for the CARTS abuse and attachment scales were found, indicating that Italian students rated their mothers and fathers as simultaneously less abusive, but also less as a source of secure attachment. Conclusions: The results of this preliminary study seem to suggest convergent validity of the Italian CARTS and the association between childhood attachment-related experiences and romantic attachment. Cultural variations were identified between Canadian and Italian students in both attachment and abuse scales. Future studies to investigate cross-cultural variations in the relational context of childhood abuse and in order to boost Italian CARTS psychometric features are warranted.

Abstract
BACKGROUND Very preterm birth (VPT; <32 weeks of gestation) has been associated with impairments in emotion regulation, social competence and communicative skills. However, the neuroanatomical mechanisms underlying such impairments have not been systematically studied. Here we investigated the functional integrity of the amygdala connectivity network in relation to the ability to recognize emotions from facial expressions in VPT adults. METHOD Thirty-six VPT-born adults and 38 age-matched controls were scanned at rest in a 3-T MRI scanner. Resting-state functional connectivity (rs-fc) was assessed with SPM8. A seed-based analysis focusing on three amygdalar subregions (centro-medial/latero-basal/superficial) was performed. Participants' ability to recognize emotions was assessed using dynamic stimuli of human faces expressing six emotions at different intensities with the Emotion Recognition Task (ERT). RESULTS VPT individuals compared to controls showed reduced rs-fc between the superficial subregion of the left amygdala, and the right posterior cingulate cortex (p = 0.017) and the left precuneus (p = 0.002). The VPT group further showed elevated rs-fc between the left superficial amygdala and the superior temporal sulcus (p = 0.008). Performance on the ERT showed that the VPT group was less able than controls to recognize anger at low levels of intensity. Anger scores were significantly associated with rs-fc between the superficial amygdala and the posterior cingulate cortex in controls but not in VPT individuals. CONCLUSIONS These findings suggest that alterations in rs-fc between the amygdala, parietal and temporal cortices could represent the mechanism linking VPT birth and deficits in emotion processing.

Abstract
Tomato cultivation farms of Southern Italy were investigated in order to evaluate the general working conditions and the levels of exposure of farm workers to pesticides, during the mixing/loading and the application of pesticides on fields. Information on working modalities, personal protective equipment, etc. was collected using a questionnaire. Inhaling and cutaneous exposure levels were measured, and the estimated pesticide total absorbed dose was compared with Admissible Daily Intakes (ADIs). Field treatments were mainly carried out by using sprayers with open cab tractors, and, in 57.9% of cases, the pesticide mixture was manually prepared by mixing pesticides in a pail, often without using gloves (59.5%). The estimated pesticides absorbed doses varied in the range 0.56–2630.31 mg (mean value, 46.9 mg), and 20% of the measured absorbed doses exceeded ADIs. The findings obtained in the 18 examined farms show a worrying situation, suggesting the investigation of many more farms, so that a statistically significant picture of tomato cultivations in Southern Italy could be formed. Besides, the planning of training courses aimed to increase workers consciousness about health risks and how they can be prevented is advisable.

Abstract
Agricultural working contexts are characterized by numerous and heterogeneous working activities, leading to a noteworthy variety of risks for workers' healthcare. Safety and health risks vary according to each specific working activity, following seasonal cycles and productive process's phases. In particular, here the attention has been focused on the main risks factors present in large farms for fruit crops production, greenhouses and silos. Preventive measures for risks management are indicated in relation to each working activity step. Together with injury risks, essentially due to work equipment and machinery, unfavourable microclimatic conditions and hazards related to the manual handling of loads are often present, as well as chemical and biological risk agents adopted during the sterilization, disinfection and fertilization of grounds, plants and storage places. The reported findings highlight the necessity of increasing the risk consciousness of agricultural operators in order to facilitate the adoption of indispensable preventive and protective measures.

Abstract
AIM Cigarette smoking is a risk factor for periodontitis incidence and progression. Contrasting results were obtained when the impact of cigarette smoking on the clinical outcomes of non-surgical periodontal therapy (NSPT) was evaluated. The present study was designed to evaluate the smoking status as outcome determinant of NSPT. METHODS Two groups of patients with different smoking status (smoker group, S, and non-smoker group, NS) were retrospectively selected from a pool of patients seeking care for periodontitis. The effectiveness of NSPT was assessed by evaluating the changes in 1) the prevalence of sites with different pocket probing depth (PPD), and 2) the patient- and site-specific bleeding. RESULTS Group S comprised of 65 patients (mean age: 45.6+/-8.7 years; 24 males and 41 females) and group NS comprised of 66 patients (mean age: 46.8+/-11.7 years; 17 males and 49 females). A statistically significant increase in the prevalence of sites with PPD< or =3 mm (P<0.000), as well as a significant decrease in the prevalence of sites with PPD 4/6 mm (P<0.000) and PPD> or =7 mm (P< or =0.01) was detected at re-evaluation. BoP scores were significantly reduced for the entire dentition (P<0.000) as well as for sites with PPD< or =3 mm (P<0.01) and PPD 4/6 mm (P<0.000) in both group S and group NS. No statistically significant differences in the post treatment change of PPD and BoP scores were detected between groups. CONCLUSION Our results seem to suggest that smoking status has a limited, if any, effect on the clinical outcomes of NSPT.

Abstract
We examined the biological reactivity in vitro of nanoparticles of organic compounds (NOC) with diameters, d = 1-3 nm, a class of combustion-generated particulate relatively unstudied compared to larger more graphitic soot particles because of their small size even though they may contribute significantly to the organic fraction of PM sampled from vehicle exhausts and urban atmospheres. We tested NOC samples collected from 2004 model vehicle emissions and laboratory flames. NOC produced a dose dependent mutagenic response in Salmonella bacteria, suggesting that NOC may add significantly to the overall mutagenicity of vehicle emissions. Incubation with peptides caused agglomeration and precipitate of the otherwise stable NOC suspension, but the chemical and/or physical nature of the NOC-peptide interactions could not be resolved. A significant cytotoxic response was measured above a critical dose of NOC in mouse embryo fibroblasts NIH3T3 cells along with possible evidence of cellular uptake by optical and confocal microscopy. The toxicological assays showed that NOC collected from flames and vehicle exhausts effectively interacted in vitro with both prokaryotic and eukaryotic cells. Differences in mutagenic potencies observed for various Salmonella strains with and without metabolic activation indicate differences in the chemical composition of NOC collected from different vehicles and flames.

Abstract
The risk evaluation related to the occupational exposure to hazardous substances can be performed either by analytical data coming from environmental and/or biological monitoring or by using models and mathematical algorithms. Models are often considered economically more advantageous, nevertheless, in order to assure their reliability, they need to be validated by objective monitoring data. A predictive model for the evaluation of risks due to the exposure to pesticides in agriculture was elaborated, and, for model validations, 20 tomato farms were examined. For each farm, information necessary to the risk evaluation by using the elaborated algorithm were collected and, simultaneously, an environmental monitoring for the evaluation of inhaling and cutaneous exposure was carried out. The potential risk was estimated by comparing analytical data from environmental monitoring with respect to ADI (Admissible Daily Intake) values, for each investigated pesticide. Then, the accordance between the potential risk and the risk given by the elaborated model was evaluated and an agreement of 85.6% was found, showing a substantial reliability of the proposed model.

Abstract
The direct HPLC enantioseparation of five pairs of new chiral pyrazole derivatives on coated cellulose- and amylose-based chiral stationary phases (Chiralpak AD, Chiralcel OJ and Chiralcel OJ-RH) and new immobilised amylose-based Chiralpak IA CSP was performed. Very high enantioselectivity factor (alpha) values were achieved in polar organic and reversed-phase conditions by using OJ-RH as CSP. Chiralpak IA exhibited an excellent chiral resolving ability in normal-phase mode and it allowed the enantioseparation of analytes investigated with resolution factors (Rs) >20. Due to its bonded nature, it was successfully employed at analytical and semipreparative scale in combination with normal-phase eluents containing "non-standards" solvents such as acetone.

Abstract
Nanoparticles of organic carbon (NOC) are formed in combustion of hydrocarbon-rich fuels and have been detected in vehicle exhausts, suggesting their presence in urban atmospheres. Epidemiological studies showed that some causal relationships exist between particle concentration in the air and a wide range of health effects, but no toxicological studies are reported on the potential health risk of particles smaller than 4 nm. The present study investigated the mutagenicity and the reactivity of NOC collected in water samples from the exhausts of diesel and gasoline engines. Mutagenicity was tested following the Ames Test, with and without metabolic activation. Reactivity was investigated by using a new approach aimed to identify electrophilic agents present in the sample material, which if introduced into the organism, could interact with nucleophilic sites of biological macromolecules (DNA and proteins), forming adducts. Given the large number of nucleophilc sites within biological macromolecules, the complexity of NOC, and the inexact knowledge of its chemical structure, this approach was simplified by examining in vitro interactions between NOC particles and model peptides through LCIMS analyses of incubation mixtures The results indicate a high reactivity and, in several cases, the mutagenicity of NOCs, thus calling for suitable biomarkers assess NOC exposure associated with vehicle emissions.

Abstract
Hospital personnel involved in antineoplastic drug preparation and administration to patients are exposed to large amounts of these drugs. Labour legislation indicates the necessity of planning monitoring strategies aimed at prevention and/or reduction of drug exposure. Monitoring strategies consist of quantitative determinations of indicators, present in environmental and biological matrices. Among the antineoplastic drugs widely used, cyclophosphamide (CP) has been identified as a suitable indicator of potential exposure to mixtures of antineoplastic drugs. Many literature methods for quantitative analysis of CP involve either liquid (LC) or gas chromatography (GC) with mass spectrometry (MS), both of which require use of a suitable internal standard. The present work focuses on the synthesis of mono- and diiodocyclophosphamide (CPI and CPI(2)) to be used as internal standard. These compounds were analyzed by GC/EI-MS/MS and LC/ESI-MS(n) using ion trap mass spectrometry. The product ion mass spectra are interpreted in terms of proposed structures of fragment ions. Iodine-chlorine substitution resulted in a weakening of the carbon-halogen bond with a noteworthy influence on the ion fragmentation processes. The proposed suitability of CPI and CPI(2) as internal standards was based on similarities to CP as regards ionization and fragmentation processes. The results obtained suggest that CPI could be used as internal standard for CP quantification by LC/ESI-MS/MS, and CPI(2) for GC/EI-MS/MS analyses.

Abstract
Biliopancreatic diversion (BPD) has made reacceptable the malabsorptive approach to the surgical treatment of obesity. The procedure, in a series of 2241 patients operated on during a 21-year period, caused a mean permanent reduction of about 75% of the initial excess weight. The indefinite weight maintenance appears to be due to the existence of a threshold absorption capacity for fat and starch, and thus energy, and the weight loss is partly due to increased resting energy expenditure. Beneficial effects other than those consequent to weight loss or reduced nutrient absorption included permanent normalization of serum glucose and cholesterol without any medication and on totally free diet in 100% of cases, both phenomena being due to a specific action of the operation. Operative mortality was less than 0.5%. Specific late complications included anemia, less than 5% with adequate iron or folate supplementation (or both); stomal ulcer, reduced to 3.2% by oral H2-blocker prophylaxis; bone demineralization, increasing up to the fourth year and tending to decrease thereafter, with need of calcium and vitamin D supplementation; neurologic complications, totally avoidable by prompt vitamin B administration to patients at risk; protein malnutrition, which was reduced to a minimum of 3% with 1.3% recurrence, in exchange with a smaller weight loss, by adapting the volume of the gastric remnant and the length of the alimentary limb to the patient's individual characteristics. It is concluded that the correct use of BPD, based on the knowledge of its mechanisms of action, can make the procedure an effective, safe one in all hands.
