High depressive symptomatology reduces emotional reactions to pictures of social interaction.

Individuals with severe depressive symptoms present diminished facial expressions compared to healthy individuals. This reduced facial expression, which occurs in most depressive patients could impair social relationships. The current study sought to investigate whether pictures with social interaction cues could elicit different modulations of facial expressions and mood states in individuals with depressive symptoms compared to healthy individuals. A total of 85 individuals were divided into depressive and non-depressive groups based on their beck depression inventory scores. Participants viewed pictures containing neutral (objects), affiliative (people interacting socially), and control (people not interacting) scenes. Electromyographic signals were collected during the entire period of visualization of the blocks, and emotional questionnaires were evaluated after each block to assess sociability and altruism (prosocial states). In non-depressed individuals, affiliative pictures increased the activity of the zygomatic muscle compared to both neutral and control pictures and reduced fear of rejection compared to neutral pictures. During the visualization of the affiliative block, zygomatic major muscle activation was higher and fear of rejection was lower in the non-depressive individuals than in the depressive. These effects reflected the low expressions of smiling and sociability to affiliative pictures in depressive individuals. These findings highlight the importance of smiling and prosocial states in social interactions, especially in these individuals.

Parents with periodontitis drive the early acquisition of dysbiotic microbiomes in their offspring.

AIM: To evaluate the microbial colonization in different dentition phases on individuals from 0 to 18 years of age belonging to families with a history of periodontitis compared to descendants of periodontally healthy parents. MATERIALS AND METHODS: The offspring of subjects with periodontitis ('Perio' group) and the offspring of periodontally healthy subjects ('Healthy' group), matched for gender and age, were included in this cross-sectional study and divided according to the dentition phase: pre-dentate, primary, mixed and permanent. The patients were clinically assessed, and their saliva was collected. DNA was extracted, and V1-V3 and V4-V5 regions of the 16S rRNA gene were sequenced. RESULTS: Fifty children of parents with periodontitis and 50 from healthy parents were included in the study and divided according to the dentition phase: pre-dentate (n = 5/group), primary dentition (n = 15/group), mixed dentition (n = 15/group) and permanent dentition (n = 15/group) in each group. The microbiome composition was different between dentitions for both groups. Children of the Perio group presented a microbial diversity different from that of the Healthy group in mixed and permanent dentitions. The more intense shift in the community occurred between primary and mixed dentition in the Perio group, while the transition between mixed and permanent dentition was the period with greater changes in the microbiome for the Healthy group. Furthermore, a pathogen-rich environment-higher prevalence and abundance of periodontitis-associated species such as Prevotella spp., Selenomonas spp., Leptotrichia spp., Filifactor alocis, Prevotella intermedia, Treponema denticola and Tannerella forsythia- was observed in the Perio group. CONCLUSIONS: The parents' periodontal status significantly affects the microbiome composition of their offspring from an early age. The mixed dentition was the phase associated with establishing a dysbiotic and pathogen-rich microbiome in descendants of parents with periodontitis.

Salivary annexin A1: A candidate biomarker for periodontitis.

AIM: To compare the salivary proteomic profile of periodontitis-affected (PA) parents and their offspring to periodontally healthy (PH) dyads in the pursuit of possible biomarkers for early diagnosis of this disease. MATERIALS AND METHODS: Unstimulated saliva samples collected from 17 pairs of PA or PH individuals and their children were submitted to mass spectrometric analyses followed by proteomic analyses. Primary PA fibroblasts were triggered towards having an inflammatory response, and an immunoenzymatic assay of its supernatant was performed to validate the obtained data. RESULTS: ANXA1, KRT4, GSTP1, HPX, A2M and KRT13 were lower in PA parents and their children, and IGHG1, CSTB, KRT9, SMR3B, IGHG4 and SERPINA1 were higher. ANXA1 presented the highest fold change, 7.1 times less produced in children of PA parents, and was selected as a potential biomarker for periodontitis. The in vitro assay also showed lower ANXA1 production by cells of PA patients. CONCLUSION: Before any clinical sign of periodontal loss, descendants of PA patients have an altered proteomic profile compared to PH individuals, presenting a lower abundance of ANXA1. This protein is suggested as a potential biomarker for periodontitis.

Immune response characterization of primary gingival fibroblasts from Grade C periodontitis patients.

BACKGROUND: Grade C, Stage 3-4 Periodontitis (Perio4C) is a rapidly destructive disease caused by an unequilibrated immune response that starts after the primary contact of the periodontopathogens with the gingival tissue. However, it is still unclear how this imbalanced response initiates and what is the role of the connective tissue cells in the progression of this disease. Thus, this study aims to assess the local immune response of Perio4C patients through the exposure of primary gingival fibroblast cells (GFs) with Aggregatibacter actinomycetemcomitans protein extract (AaPE) and the quantification of the inflammatory cytokines interleukin (IL)-4, IL-17, tumor necrosis factor (TNF)-α, IL-1ß, interferon (IFN)-γ, and IL-10 super-family members (IL-10, IL-19, and IL-24) secreted by them. METHODS: Gingival biopsies from nine periodontally health (PH) and eight Perio4C patients were harvested, and the primary culture of GFs was obtained. The cells were exposed to AaPE (5 and 20 µg/ml) and 12-myristate 13-phorbol acetate and ionomycin - calcium salt (PMA). The supernatant was collected after 1.5 and 3 h, and a cytokine panel was evaluated. RESULTS: Clustering analysis indicated dissimilar and stimuli-dependent cytokine production between Perio4C and PH subjects. Perio4C GFs presented lower production of IL-4, TNF-α, IFN-γ, IL-17, IL-10, IL-24, and IL-19, while IL-1ß levels were similar to the PH group, leading to a disruption in the pro-/anti-inflammatory cytokine ratio (p < 0.05). IL-1ß and IL-10 super-family were the most discriminative representants for PH and Perio4C, respectively. CONCLUSION: GFs from individuals with Perio4C tended to hypo-respond to stimulation with AaPE, producing lower concentrations of some pro- and anti-inflammatory molecules, trending to develop a pro-inflammatory extracellular environment.

Long-term benefits of heart rate variability biofeedback training in older adults with different levels of social interaction: a pilot study.

To test whether heart rate variability (HRV) biofeedback training benefits older adults with different social interaction levels. METHODS: 32 older adults (16 were institutionalized and 16 were not). Both groups received 14 sessions, 15 min, 3 times a week, with half of the individuals receiving HRV biofeedback training and the other half receiving control training. The following parameters were assessed immediately before and after training, and 4.5 weeks after the last session (follow-up period): aerobic conditioning, anthropometric data, emotional scores, and HRV components. RESULTS: Before the training, the institutionalized individuals had higher scores of loneliness (p < 0.01) and depression (p < 0.0001) and lower social touches (p < 0.0001), body mass (p = 0.04), and body fat percentage (p = 0.002) than the non-institutionalized individuals. HRV biofeedback improved symptoms of depression in both groups. HRV improved only in the non-institutionalized group, and loneliness only in the institutionalized group. Lastly, all changes persisted after the follow-up period. CONCLUSIONS: HRV biofeedback training was effective in improving symptoms of depression in older adults. Improvement of HRV and loneliness was dependent on the level of social interaction.

Decreased self-reported receiving of social touch and social support predict loneliness in healthy adults.

Loneliness has emerged as a public health concern. Previous research has reported its deleterious effects on physical and mental health; however, some specific psychophysiological mechanisms in healthy adults remain to be elucidated. The aim of the current study is to investigate whether self-reported social support and social touch (giving and receiving social touch), as well as resting heart rate variability (HRV), are significant negative predictors of loneliness in healthy adults. The study sample consists of 120 healthy students (50% female) with a mean age of 21.85 years old (DP= 2.21). The students were asked to complete a psychiatric screening questionnaire utilizing loneliness, social support, and social touch scales. HRV was derived from an electrocardiographic signal recorded for 15 min, with the participant relaxed in a supine position. Linear regression analyses were conducted to evaluate loneliness as a function of social support, social touch (giving or receiving touch), and resting HRV. The results show that social support (p< 0.001) and social touch, specifically receiving touch (p< 0.002), accounted for a significant proportion of the variance in loneliness. However, neither giving touch nor resting HRV was a significant predictor of loneliness. The current study highlights specific psychosocial factors in healthy adults that should be considered as promising pathways in order to reduce or work toward preventing loneliness, thus promoting better health and well-being.

Open flap debridement compared to repeated applications of photodynamic therapy in the treatment of residual pockets: A randomized clinical trial.

BACKGROUND: The aim of the present study was to compare repeated applications of antimicrobial photodynamic therapy (aPDT) to open flap debridement (OFD) in the treatment of residual periodontal pockets in non-furcation sites. METHODS: Forty-six subjects with a diagnosis of Stage III or IV Grade C periodontitis, that had been previously treated, participated in the study.  Residual pockets were divided between two groups: (1) aPDT group: received ultrasonic periodontal debridement followed by immediate application of aPDT, and repeated on1st, 2nd, 7th, and 14th days; and (2) OFD group: treated by modified papilla preservation technique, where granulation tissue and visible calculus were removed with hand curettes and an ultrasonic device. Clinical, immunological, and microbiological parameters were evaluated before and after treatment. RESULTS: Both treatments were effective reducing clinical parameters of disease. OFD resulted in a greater mean probing pocket depths (PPD) reduction in deep pockets (p = 0.001). However, aPDT resulted in a lower occurrence of gingival recession (GR), dentin hypersensitivity (DH) and analgesic intake. Reduction in Porphyromonas gingivalis was observed in both groups. Only the OFD group had a significant reduction in Aggregatibacter actinomycetemcomitans. aPDT group had greater increase in interleukin 10 (IL-10) levels and a greater reduction of interleukin 1 beta (IL-1ß) at 14 days when compared to the OFD group (p < 0.05). CONCLUSION: OFD was superior in reducing PPD in deep pockets compared to the aPDT. However, OFD resulted in greater GR.  Both treatments lowered P. gingivalis levels but only OFD reduced levels of A. actinomycemtemcomitans.

Childhood Hypophosphatasia Associated with a Novel Biallelic ALPL Variant at the TNSALP Dimer Interface.

The goal of this study was to perform a clinical and molecular investigation in an eight-year-old female child diagnosed with hypophosphatasia (HPP). The proband and her family were evaluated by medical and dental histories, biochemical analyses, radiographic imaging, and genetic analysis of the tissue-nonspecific alkaline phosphatase (ALPL) gene. A bioinformatic analysis was performed to predict the structural and functional impact of the point mutations in the tissue-nonspecific alkaline phosphatase (TNSALP) molecule and to define their potential contribution to the phenotype. We identified a novel combination of heterozygous ALPL missense variants in the proband, p.Ala33Val and p.Asn47His, compatible with an autosomal recessive mode of inheritance and resulting in skeletal and dental phenotypes. Computational modeling showed that the affected Asn47 residue is located in the coil structure close to the N-terminal α-helix, whereas the affected Ala33 residue is localized in the N-terminal α-helix. Both affected residues are located close to the homodimer interface, suggesting they may impair TNSALP dimer formation and stability. Clinical and biochemical follow-up revealed improvements after six years of ERT. Reporting this novel combination of ALPL variants in childhood HPP provides new insights into genotype-phenotype associations for HPP and specific sites within the TNSALP molecule potentially related to a childhood-onset HPP and skeletal and dental manifestations. Beneficial effects of ERT are implicated in skeletal and dental tissues.

Clinical, radiographic, and patient-centered outcomes after use of enamel matrix proteins for the treatment of intrabony defects in patients with aggressive periodontitis: A 12-month multicenter clinical trial.

BACKGROUND: The aim of this study was to evaluate the clinical, radiographic and patient-centered results of enamel matrix derivative (EMD) therapy in intrabony defects in aggressive periodontitis (AgP) patients and compare them with those in chronic periodontitis (CP) patients. METHODS: Sixty intrabony defects in AgP and CP patients associated with ≥ 6 mm residual probing pocket depth (PPD) were included and randomly assigned to one of three groups: AgP+CS (conservative surgery) (n = 20); AgP+CS/EMD (n = 20); CP+CS/EMD (n  =  20). Clinical parameters were measured at baseline and after 6 and 12 months. Defect resolution (DR) and bone filling (BF) were used for radiographic analysis. The quality of life was recorded at baseline and 6 months using OHIP-14 and VAS scale in the early post-therapy period. RESULTS: PPD and relative clinical attachment level (rCAL) improved for all groups during follow-up (P ≤ 0.05), and AgP+CS/EMD presented a higher rCAL gain (2.4 ± 1.0 mm) when compared to AgP control patients (1.6 ± 1.6 mm, P ≤ 0.05) after 12 months. No difference was observed between AgP+CS/EMD and CP+CS/EMD groups (P > 0.05). No radiographic differences were observed among groups at any time point (P > 0.05). All the groups reported a positive impact on OHIP-14 total score, without differences among them. CONCLUSIONS: EMD therapy of intrabony defects promotes additional benefits in AgP patients, presenting a similar regeneration rate compared to CP patients, and has proven to be a viable therapy for the treatment of individuals with AgP.

Omega-3 Fatty Acids and Low-Dose Aspirin in the Treatment of Periodontitis and Metabolic Syndrome: Case Report.

AIMS: To investigate the use of ω-3 fatty acids and low-dose aspirin as adjuncts to periodontal debridement in a patient with periodontitis and metabolic syndrome. METHODS: Periodontal and systemic parameters were assessed at baseline and 6 months. Gingival crevicular fluid was analyzed for interleukin (IL)-1ß, IL-6 and interferon (IFN)-γ levels by multiplex ELISA at baseline, 3 and 6 months. RESULTS: The treatment was effective in reducing probing depth, clinical attachment level, bleeding on probing and plaque index, and glycated hemoglobin, triglycerides IL-1ß, IL-6 and IFN-γ levels over time. CONCLUSIONS: The adjunctive use of ω-3 and low-dose aspirin to periodontal debridement might have potential benefits in the treatment of periodontitis in a patient with metabolic syndrome.

Omega-3 PUFA and aspirin as adjuncts to periodontal debridement in patients with periodontitis and type 2 diabetes mellitus: Randomized clinical trial.

BACKGROUND: Supplementation with omega-3 polyunsaturated fatty acids (ω-3 PUFA) and low-dose aspirin (ASA) have been proposed as a host modulation regimen to control chronic inflammatory diseases. The aim of this study was to investigate the clinical and immunological impact of orally administered ω-3 PUFA and ASA as adjuncts to periodontal debridement for the treatment of periodontitis in patients type 2 diabetes. METHODS: Seventy-five patients (n = 25/group) were randomly assigned to receive placebo and periodontal debridement (CG), ω-3 PUFA + ASA (3 g of fish oil/d + 100 mg ASA/d for 2 months) after periodontal debridement (test group [TG]1), or ω-3 PUFA + ASA (3 g of fish oil/d + 100 mg ASA/d for 2 months) before periodontal debridement (TG2). Periodontal parameters and GCF were collected at baseline (t0), 3 months after periodontal debridement and ω-3 PUFA + ASA or placebo for TG1 and CG (t1), after ω-3 PUFA + ASA (before periodontal debridement) for TG2 (t1), and 6 months after periodontal debridement (all groups) (t2). GCF was analyzed for cytokine levels by multiplex ELISA. RESULTS: Ten patients (40%) in TG1 and nine patients (36%) in TG2 achieved the clinical endpoint for treatment (less than or equal to four sites with probing depth ≥ 5 mm), as opposed to four (16%) in CG. There was clinical attachment gain in moderate and deep pockets for TG1. IFN-γ and interleukin (IL)-8 levels decreased over time for both test groups. IL-6 levels were lower for TG1. HbA1c levels reduced for TG1. CONCLUSION: Adjunctive ω-3 and ASA after periodontal debridement provides clinical and immunological benefits to the treatment of periodontitis in patients with type 2 diabetes.

Novel rare frameshift variation in aggressive periodontitis: Exomic and familial-screening analysis.

BACKGROUND: Aggressive periodontitis (AgP), currently periodontitis grade C, presents early onset, rapid progression, and a poorly established genetic association. Thus, this study aimed to identify genetic variants associated with AgP via whole exome sequencing (WES) through a familial screening approach. METHODS: WES was performed in two nuclear families, including a proband and a parent affected by AgP and an unaffected parent and sibling. Common variants among affected individuals, excluding those common to healthy people, from each family, composed the data set associated with AgP. In silico analysis evaluated the impact of each variant on protein structure and protein-protein interactions. Moreover, identified deleterious variants were validated in a populational analysis (n = 96). RESULTS: The missense single nucleotide variations (SNVs) rs142548867 in EEFSEC (c.668C>T), rs574301770 in ZNF136 (c.466C>G), and rs72821893 in KRT25 (c.800G>A) and the frameshift indels rs37146475 in GPRC6A (c.2323-2324insT) and c.1366_1372insGGAGCAG in ELN were identified in AgP and have a predicted functional impact on proteins. In silico analysis indicated that the indel in GPRC6A generates a loss of the C-terminal tail of the Gprca protein. Furthermore, this SNV was significantly associated with AgP in a population-based investigation. CONCLUSION: Novel frameshift variation in GPRC6A (c.2323-2324insT) was identified as a potential genetic alteration associated with AgP occurrence.

Avaliação da suplementação diária de ácidos graxos poli-insaturados de ômega-3 e aspirina em baixa dosagem no tratamento de periodontite agressiva generalizada: estudos clínicos controlados randomizados / Evaluation of omega-3 polyunsaturated fatty acids daily supplementation plus low-dose aspirin to treat generalized aggressive periodontitis: randomized controlled clinical trials

A destruição periodontal resulta principalmente da resposta inflamatória exacerbada do hospedeiro frente ao desafio bacteriano. Por isso, pesquisas envolvendo a modulação da resposta do hospedeiro têm sido desenvolvidas com o objetivo de facilitar a resolução da inflamação, bem como promover reparação tecidual e estabilidade periodontal. Recentemente, o uso de ácidos graxos poli-insaturados de ômega-3 (AGP Ω-3) e ácido acetilsalicílico (AAS) foi relacionado à produção de mediadores lipídicos mais bioativos e à melhores resultados clínicos no tratamento de periodontite crônica. Desse modo, pesquisas envolvendo modulação das respostas inflamatórias de portadores de periodontite agressiva (PAg) podem ser de grande valia. Assim, o objetivo dos presentes estudos clínicos controlados randomizados foi avaliar a utilização da suplementação de 900 mg AGP Ω-3 e 100 mg de AAS por 180 dias como adjuvantes ao tratamento de PAg generalizada (PAgG). (1) Selecionou-se 38 pacientes com PAgG os quais receberam debridamento subgengival associado a AGP Ω-3 e AAS (n=19) ou placebo (n=19). Ambos os grupos apresentaram diminuição (p<0,05) em todos os parâmetros clínicos avaliados, bem como em IL-1ß, sem diferença entre os tratamentos (p>0,05). O nível de TIMP-2 diminuiu significantemente no grupo controle, porém se manteve estável no grupo teste. Concluiu-se que a nova terapia proposta não trouxe benefícios clínicos no tratamento não-cirúrgico de PAgG. (2) Selecionou-se 34 pacientes com PAgG previamente submetidos à terapia básica que apresentavam bolsas residuais e foram submetidos à cirurgia de acesso para raspagem e alisamento radicular associado a AGP Ω-3 e AAS (n=17) ou placebo (n=17). Após 6 meses, ambos os grupos obtiveram diminuição na PS (p<0,05), porém somente o grupo teste obteve ganho no NIC na comparação intergrupo (p=0,02), assim como apresentou menor recessão gengival (p=0,03), diminuição da hipersensibilidade dentinária (p=0,01), menor consumo de analgésicos (p=0,02) e diminuição intragrupo de IL-10 (p<0,05). Concluiu-se que a nova terapia proposta trouxe benefícios clínicos no tratamento de bolsas residuais de pacientes com PAgG(AU)

Periodontal destruction results mainly from the exacerbated host inflammatory response to the bacterial challenge. For this reason, research involving the modulation of host response has been developed aiming to facilitate the resolution of inflammation, as well as to promote tissue repair and periodontal stability. Recently, the use of omega-3 polyunsaturated fatty acids (Ω-3 PUFA) and low-dose acetylsalicylic acid (ASA) was related to the production of enhanced lipidic mediators and to better clinical outcomes in the treatment of chronic periodontitis. Thus, the aim of the present randomized controlled clinical trials was to evaluate the use of 900 mg Ω-3PUFA and 100 mg ASA for 180 days as adjuvants to the treatment of generalized aggressive periodontitis (GAgP). (1) Thirty-eight GAgP patients were submitted to subgingival debridement associated with Ω-3 PUFA and ASA (n=19) or placebo (n=19). Both groups showed a statistically significant decrease (p<0.05) in all clinical parameters, as well as a decrease in IL-1ß, with no difference between treatments (p>0.05). The TIMP-2 level significantly decreased in the control group and remained stable in the test group. It was concluded that the proposed new therapy did not bring clinical benefits in the non-surgical treatment (NST) of GAgP. (2) Thirty-four GAgP patients previously submitted to NST with residual pockets were selected and underwent open flap debridement associated with Ω-3 PUFA 3 and ASA (n=17) or placebo (n=17). After 6 months, both therapies led to decreased PD (p>0.05), but only the test group had CAL gain in the intergroup comparison (p=0,02), as well as presented less gingival recession (p=0,03), decreased dentin hypersensitivity (p=0,01), lower consumption of analgesics (p=0,02) and significant intragroup reduction of IL-10 (p<0.05). It was concluded that the proposed new therapy brought clinical benefits in the surgical treatment of GAgP patient(AU)

Two different antibiotic protocols as adjuncts to one-stage full-mouth ultrasonic debridement to treat generalized aggressive periodontitis: A pilot randomized controlled clinical trial.

BACKGROUND: To assess the clinical and microbiological responses of amoxicillin + metronidazole (AMX + MET) versus clarithromycin (CLM) as adjuncts to one-stage full-mouth ultrasonic debridement (FMUD) in the treatment of generalized aggressive periodontitis (GAgP). METHODS: For this parallel, double-masked, pilot randomized clinical trial, 46 patients with GAgP were selected and randomly assigned into two groups: AMX+MET group (n = 23): FMUD associated with AMX (500 mg three times a day) and MET (400 mg three times a day) for 7 days; and CLM group (n = 23): FMUD associated with CLM (500 mg twice a day) for 7 days. Clinical parameters were evaluated at baseline, 3, and 6 months post-treatment. The levels of Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, and Fusobacterium nucleatum from subgingival biofilm were determined by quantitative polymerase chain reaction. RESULTS: Both treatments significantly improved all clinical parameters compared with baseline and promoted a significant reduction of A. actinomycetemcomitans and P. gingivalis counts (P > 0.05). CLM succeeded in decreasing T. forsythia at 6 months (P < 0.05), but no antibiotic was able to reduce F. nucleatum. There was no difference between the two protocols regarding the reported adverse effects (P > 0.05). CONCLUSIONS: The results suggest that CLM is not superior than AMX + MET in the treatment of GAgP. However, this antibiotic led to good clinical outcomes and may be a possible alternative to AMX+MET in the treatment of severe periodontitis in young patients. Future studies with larger sample sizes are needed to confirm this statement (NCT02969928).

The More Doctors Program and the rearrangement of medical residency education focused on Family and Community Medicine / O Programa Mais Médicos e o reordenamento da formação da residência médica com enfoque na Medicina de Família e Comunidade / El Programa Más Médicos y la reorganización de la formación de residencia médica con enfoque en Medicina de Familia y Comunidad

Abstract The More Doctors Program (PMM) was created in 2013 to address problems such as the insufficient number and unequal distribution of doctors, and their inadequate education profile to fulfill the population needs. Among other axes, it proposes changes in medical education, including the rearrangement and expansion of residency, suggesting one seat for every medical course graduate. This study reflects upon the elements that were essential to propose and implement changes in medical residency through PMM. The following advances were identified: better distribution of residency seats across Brazil; diversification of universalization strategies; regulations for residency seats focused on Family and Community Medicine; and preceptorship qualification. The conclusion section presents the challenges faced by the required institutional effort to maintain PMM's actions in order to regulate residency and expand actions to other professions.(AU)

Evaluation of the local effect of nonsurgical periodontal treatment with and without systemic antibiotic and photodynamic therapy in generalized aggressive periodontitis. A randomized clinical trial.

BACKGROUND: This study's aim was to evaluate the local effect of clarithromycin associated with antimicrobial photodynamic therapy (aPDT) in the treatment of generalized aggressive periodontitis. MATERIALS AND METHODS: The study sample comprised 72 periodontal pockets on single-rooted teeth in multiple quadrants, with both probing depth and clinical attachment level ≥5 mm, and with bleeding on probing. The pockets were randomly distributed into four groups (n = 18 each) that received ultrasonic periodontal debridement in addition to placebo (the UPD group), systemic clarithromycin (the UPD + CLM group), aPDT (the UPD + aPDT group), or both systemic clarithromycin and aPDT (the UPD + CLM + aPDT group). The measurements were performed prior to treatment (baseline) and at 3 and 6 months postoperatively. The following parameters were evaluated: plaque index, bleeding on probing, probing depth, gingival recession, and clinical attachment level. A 5% significance level was used in the statistical analysis. RESULTS: At 3 months, UPD + aPDT, UPD + CLM, and UPD + CLM + aPDT groups all exhibited reduced probing depths relative to the UPD group (p < 0.05). However, at 6 months, the reduction in mean probing depth was greater in the antibiotic groups (UPD+CLM and UPD+CLM+aPDT) than in the UPD and UPD+aPDT groups (p < 0.05). Regarding clinical attachment level, only the UPD+CLM+aPDT group presented a significant gain relative to the UPD and UPD + PDT groups (p < 0.05). CONCLUSIONS: Ultrasonic periodontal debridement has greater clinical advantages when associated with clarithromycin than with associated with aPDT. However, the joint application of aPDT and clarithromycin did not present additional benefits.

Bonding Pictures: Affective Ratings Are Specifically Associated to Loneliness But Not to Empathy.

Responding to pro-social cues plays an important adaptive role in humans. Our aims were (i) to create a catalog of bonding and matched-control pictures to compare the emotional reports of valence and arousal with the International Affective Picture System (IAPS) pictures; (ii) to verify sex influence on the valence and arousal of bonding and matched-control pictures; (iii) to investigate if empathy and loneliness traits exert a specific influence on emotional reports for the bonding pictures. To provide a finer tool for social interaction studies, the present work defined two new sets of pictures consisting of "interacting dyads" (Bonding: N = 70) and matched controls "non-interacting dyads" (Controls: N = 70). The dyads could be either a child and an adult, or two children. Participants (N = 283, 182 women) were divided in 10 groups for the experimental sessions. The task was to rate the hedonic valence and emotional arousal of bonding and controls; and of pleasant, neutral, and unpleasant pictures from the IAPS. Effects of social-related traits, empathy and loneliness, on affective ratings were tested. Participants rated bonding pictures as more pleasant and arousing than control ones. Ratings did not differentiate bonding from IAPS pleasant pictures. Control pictures showed lower ratings than pleasant but higher ratings than neutral IAPS pictures. Women rated bonding and control pictures as more positive than men. There was no sex difference for arousal ratings. High empathic participants rated bonding and control pictures higher than low empathic participants. Also, they rated pleasant IAPS pictures more positive and arousing; and unpleasant pictures more negative and arousing than the less empathic ones. Loneliness trait, on the other hand, affected very specifically the ratings of bonding pictures; lonelier participants rated them less pleasant and less arousing than less lonely. Loneliness trait did not modulate ratings of other categories. In conclusion, high empathy seems related to emotional strength in general, while high loneliness seems to weaken the engagement in social interaction cues.
