CONSORT statement adherence and risk of bias in randomized controlled trials on deep caries management: a meta-research.

BACKGROUND: Recently, trials have supported changes in deep caries management. However, reporting might lack details, affecting interpretation and implementation. Thus, we aimed to evaluate the adherence to the CONSORT statement and the risk of bias of randomized controlled trials (RCTs) on deep caries management published in pediatric dental journals. METHODS: We searched PubMed for RCTs in six pediatric dental journals between 2010 and 2022, focusing on deep caries lesion management. Adherence to the CONSORT guideline and the risk of bias were assessed using a modified tool with 19 items; each scored from 0 to 2 (maximum of 38 points), and the Cochrane risk-of-bias (RoB 2) tool. We performed descriptive and regression analyses (α = 5%). RESULTS: We analyzed 127 RCTs. The mean (standard deviation) CONSORT adherence score was 21.1 (6.7). Notably, 96.1% of the studies received a score of 2 for the "intervention" item, whereas 83.5% scored 0 for the "estimated effect size". The risk of bias assessment revealed that 40.2% of the RCTs were at high risk, 59% were at low risk, and 0.8% were at low risk. RCTs with a high risk of bias had lower CONSORT scores (p<0.001) than those with low or some concerns. RCTs published in journals without the endorsement of the CONSORT statement had lower scores than those in journals with the endorsement of the CONSORT statement. Older RCTs (6-10 years old and more than 10 years old) showed significantly lower CONSORT statement compliance than trials published recently within 5 years. CONCLUSION: Adherence to the CONSORT was relatively low among the investigated RCTs. Moreover, lower adherence to the CONSORT was associated with a higher risk of bias. TRIAL REGISTRATION: This study protocol was prospectively registered on the Open Science Framework - DOI ( 10.17605/OSF.IO/V6SYZ ).

Decision-making on peri-implant mucositis management and treatment approaches.

Peri-implant mucositis is characterised by inflammation of soft tissues surrounding a dental implant without associated bone loss beyond initial remodelling. Early detection and timely intervention are critical to prevent its progression to peri-implantitis. This paper focuses on various treatment options for treating peri-implant mucositis. The cornerstone of professional treatment lies in the mechanical disruption and removal of microbial biofilms around the implant. This can be achieved through careful use of manual or powered instruments, such as ultrasonic scalers or air polishing devices. However, there is a need for further research to determine the most effective single approach for treating peri-implant mucositis. Current evidence does not support the combination of mechanical debridement with locally administered antibiotics. Contrarily, evidence strongly supports the removal, cleaning, and modifications of prostheses to improve both self-performance and professional cleanability. The use of adjunctive therapies like photodynamic therapy and diode laser, in conjunction with mechanical instrumentation, is not currently recommended due to the limited strength of available evidence. Preventive measures emphasise the importance of comprehensive oral hygiene care, encompassing professional guidance and at-home practices, to manage biofilms effectively. This encompasses oral hygiene instruction, regular debridement, and maintenance care. Supporting peri-implant therapy is also vital for ongoing implant monitoring, preventing the recurrence of mucositis, and halting its progression to peri-implantitis. This multifaceted approach is key to effectively managing and treating peri-implant mucositis.

Sit less and move more! A cross-sectional study of the associations between physical activity and sedentary behaviors with inhibitory control in Brazilian adults.

OBJECTIVE: To investigate the independent and joint associations between sedentary behaviors (SB) and physical activity (PA) with inhibitory control (IC) in adults. METHODS: A total of 111 participants (median age = 30 years; 60% women), completed the Stroop Color-Words test to assess IC. They also wore accelerometers for seven days to measure SB, light PA, moderate-to-vigorous PA (MVPA), and daily steps. We previously set cutoff points for SB and PA measurements and tested them to determine their association with IC. All analyses were adjusted for potential confounding factors including age, gender, post-secondary education, income, body mass index, and accelerometer wear time. RESULTS: Low SB, high MVPA, and high daily steps were independently associated with a better IC compared to their respective counterparts. Adults with low levels of SB and light PA demonstrated better IC performance (ß = -227.67, 95%CI = -434.14 to -21.20) compared to those with high SB and low light PA. Conversely, individuals with high SB and high light PA exhibited worse performance (ß = 126.80, 95%CI = 2.11 to 251.50) than those in the high SB and low light PA group. Furthermore, the joint association of low SB with high MVPA (ß = -491.12, 95%CI = -689.23 to -293.01) or low SB with high daily steps (ß = -254.29, 95%CI = -416.41 to -92.16) demonstrated better IC performance compared to those with high SB and low MVPA or low daily steps. CONCLUSION: Our findings highlight independent and joint associations between low SB, high MVPA, and high daily steps with enhanced IC in adults.

Vitamin D levels in patients attending a tertiary care hospital in Mogadishu, Somalia: a retrospective review of 28,125 cases.

OBJECTIVE: The objective of this study was to identify the prevalence and risk factors for vitamin D deficiency among patients attending a tertiary hospital in Mogadishu, Somalia. METHODS: This retrospective study examined the results of serum 25-hydroxy-vitamin D tests of 28,125 patients admitted to Somalia Mogadishu-Turkey Training and Research Hospital between January 2017 and December 2021. Vitamin D insufficiency is defined as 20-30 ng/mL, deficiency as 10-19 ng/mL, and severe deficiency as <10 ng/mL. RESULTS: A total of 28,125 patients with a mean age of 44.27±20.4 years were included in the study. The majority of patients were in the age group of 19-40 years. The mean serum level of 25-hydroxy-vitamin D was 28.42±15.34 ng/mL. Of the patients included in the study, 5.8% (1,618/28,125) had vitamin D sufficiency, 6.5% (1,826/28,125) had vitamin D insufficiency, 41.8% (11,761/28,125) had vitamin D deficiency, and 45.9% (12,920/28,125) had severe vitamin D deficiency. The mean serum 25-hydroxy-vitamin D levels were lower in females than in males (p<0.001). CONCLUSION: The study indicated a high prevalence of vitamin deficiency among patients attending the largest tertiary care hospital, particularly female patients and older people. It is recommended to develop educational and awareness programs, and campaigns to reduce vitamin D deficiency in the population, especially those at high risk.

Automatic processes moderate the association between reflective processes and movement behavior: A cross-sectional study.

Dual-process theories postulate that both reflective and automatic processes regulate health behavior. Further research is required to test the basic postulates of dual-process theories. We investigated the direct associations and moderating effect between automatic processes and multiple indicators of reflective processes on various levels of physical activity and sedentary behavior assessed using accelerometry in adults who were not participating in regular physical exercise programs. This cross-sectional study included 257 adults. Each participant completed a computerized test for automatic associations, a set of questions assessing reflective processes, a seven-day assessment using accelerometers to determine their levels of physical activity and sedentary behavior. The results showed a direct relationship between perceived benefits (B = 15.90, p = 0.043), perceived cons (B = -12.81, p = 0.034), decisional intention (B = -0.07, p = 0.049) with light physical activity, and self-efficacy with daily steps (B = 485.71, p = 0.008). There was a positive association between intention strength and daily steps when implicit associations favored physical activity (b = 623.36, LLCI = 79.09, ULCI = 1167.62, p = 0.025); a negative association between self-efficacy and sedentary behavior when implicit associations favored sedentary behavior (b = -25.73, LLCI = -49.77, ULCI = -1.70, p = 0.035); and a positive association between intention strength and sedentary behavior when implicit associations favored physical activity (b = 34.18, LLCI = 8.81, ULCI = 59.56, p = 0.008). These findings underscore the importance of considering the interplay between reflective and automatic processes in shaping movement behavior.

The effect of a multicomponent oral care regimen on gingival inflammation: A randomized controlled clinical trial.

BACKGROUND: Oral care regimens can be explored to improve oral health in patients with gingivitis. This study aimed to evaluate the efficacy of a multicomponent oral care regimen with a dual zinc plus arginine (DZA) toothpaste and cetylpyridinium chloride with zinc lactate (CPC + Zn) mouthwash in reducing gingival bleeding in patients with gingivitis. METHODS: This randomized clinical trial included 94 participants with gingivitis who were randomized into two groups: the DZA/CPC + Zn group, which used a 1450-ppm fluoride toothpaste containing 0.96% zinc plus 1.5% arginine and a fluoride-containing mouthwash with 0.075% CPC and 0.28% zinc lactate, and the control group, which used a 1450-ppm fluoride toothpaste and a placebo mouthwash for 6 months. All participants were examined by a blinded examiner who measured the gingival index, plaque index, and gingival severity index. Data were analyzed using paired t test, independent t test, and analysis of covariance (ANCOVA). RESULTS: Both groups presented statistically significant reductions in all clinical parameters compared to baseline. The DZA/CPC + Zn group exhibited significantly greater reductions in gingival index, gingival severity index, proximal gingival index, plaque index and proximal plaque index compared to the control group at 1, 3, and 6 months. Furthermore, DZA/CPC + Zn significantly decreased the percentage of patients with generalized gingivitis over a 6-month follow-up period. However, differences between the DZA/CPC + Zn and the control groups were not maintained after both groups established similar regimens with fluoride toothpaste. CONCLUSION: The multicomponent oral care regimen consisting of DZA toothpaste and CPC + Zn mouthwash is effective in reducing gingival inflammation and supragingival biofilm in patients with gingivitis.

Intensity-Dependent Influence of Interoceptive Accuracy on Psychophysiological Responses During Aerobic Exercise in Physically Inactive Men.

We aimed to investigate the influence of interoceptive accuracy on affective valence, arousal, and ratings of perceived exertion (RPE) during 20 minutes of aerobic exercise at both moderate and heavy intensity among physically inactive men. We divided our participant sample into men with poor heartbeat perception (PHP, n = 13) and good heartbeat perception (GHP, n = 15), based on their cardioceptive accuracy. We measured their heart rate reserve (%HRreserve), perceived affective valence (Feeling Scale; +5/-5), perceived arousal (Felt Arousal Scale, 0-6), and ratings of perceived effort (RPE; Borg scale 6-20) every five minutes during an exercise session on a bicycle ergometer. During moderate-intensity aerobic exercise, the GHP group presented a greater decline in affective valence (p = 0.010; d = 1.06) and a greater increase in RPE (p = 0.004; d = 1.20) compared to the PHP group, with no group differences in %HRreserve (p = 0.590) and arousal (p = 0.629). Psychophysiological and physiological responses to the heavy-intensity aerobic exercise were not different between groups. We concluded that the influence of interoceptive accuracy on psychophysiological responses during submaximal fixed-intensity aerobic exercise was intensity-dependent in these physically inactive men.

Effect of magnesium sulfate with ketamine infusions on intraoperative and postoperative analgesia in cancer breast surgeries: a randomized double-blind trial

Abstract Background Opioids are the cornerstone in managing postoperative pain; however, they have many side effects. Ketamine and Magnesium (Mg) are NMDA receptor antagonists used as adjuvant analgesics to decrease postoperative opioid consumption. Objective We assumed that adding Mg to ketamine infusion can improve the intraoperative and postoperative analgesic efficacy of ketamine infusion alone in cancer breast surgeries. Methods Ninety patients aged between 18 and 65 years and undergoing elective cancer breast surgery were included in this prospective randomized, double-blind study. Group K received ketamine 0.5 mg.kg-1 bolus then 0.12 mg.kg-1.h-1 infusion for the first 24 hours postoperatively. Group KM: received ketamine 0.5 mg.kg-1 and Mg sulfate 50 mg.kg-1, then ketamine 0.12 mg.kg-1.h-1 and Mg sulfate 8 mg.kg-1.h-1 infusions for the first 24 hours postoperative. The primary outcome was the morphine consumption in the first 24 hours postoperative, while the secondary outcomes were: intraoperative fentanyl consumption, NRS, side effects, and chronic postoperative pain. Results Group KM had less postoperative opioid consumption (14.12 ± 5.11 mg) than Group K (19.43 ± 6.8 mg). Also, Group KM had less intraoperative fentanyl consumption. Both groups were similar in postoperative NRS scores, the incidence of side effects related to opioids, and chronic neuropathic pain. Conclusion Adding Mg to ketamine infusion can safely improve intraoperative and postoperative analgesia with opioid-sparing effect in cancer breast surgery.

The influence of smoking on the incidence of peri-implantitis: A systematic review and meta-analysis.

OBJECTIVE: The aim of this study was to systematically analyze the influence of smoking on the incidence of peri-implantitis. MATERIALS AND METHODS: The search was performed in the National Library of Medicine (MEDLINE-PubMed), SCOPUS, EMBASE, and ISI Web of Science databases (finished on November 30, 2022). Systematic review and meta-analysis were conducted according to PRISMA statement. Prospective cohort studies that evaluate the incidence of peri-implantitis in smokers and non-smokers were included. Two authors independently searched for eligible studies, screened titles, and abstracts, did the full-text analysis, extracted data, and performed the risk-of-bias assessment. The results were summarized through random-effects meta-analyses. The GRADE method was used to determine the certainty of evidence. RESULTS: A total of 7 studies with 702 patients and 1959 implants were included for analysis. The meta-analysis revealed a significant difference between smokers and non-smokers for the risk of peri-implantitis in the implant-based (p < .0001) and patient-based analysis (p = .003). A strong association between smoking and the risk for peri-implantitis was verified at the implant level (RR: 2.04, 95% CI: 1.46-1.85) and the patient level (RR: 2.79, 95% CI: 1.42-5.50). CONCLUSIONS: Moderate certainty evidence suggests that smoking is associated with peri-implantitis compared to non-smoking at the patient and implant levels.

Group KM: received ketamine 0.5.ßmg.kg...1 and Mg sulfate 50.ßmg.kg...1, then ketamine 0.12.ßmg.kg...1.h...1 and Mg sulfate 8.ßmg.kg...1.h...1 infusions for the first 24.ßhours postoperative. The primary outcome was the morphine consumption in the first 24.ßhours postoperative, while the secondary outcomes were: intraoperative fentanyl consumption, NRS, side effects, and chronic postoperative pain. RESULTS: Group KM had less postoperative opioid consumption (14.12.ß...ß5.11.ßmg) than Group K (19.43.ß...ß6.8.ßmg). Also, Group KM had less intraoperative fentanyl consumption. Both groups were similar in postoperative NRS scores, the incidence of side effects related to opioids, and chronic neuropathic pain. CONCLUSION: Adding Mg to ketamine infusion can safely improve intraoperative and postoperative analgesia with opioid-sparing effect in cancer breast surgery.

Effects of antimicrobial mouthwashes on the human oral microbiome: Systematic review of controlled clinical trials.

OBJECTIVES: This review aimed to assess the impact of mouthwashes on the composition of the human oral microbiome. METHOD: An electronic search algorithm was adapted to MEDLINE-PubMed, Scopus, Embase and ISI Web of Science, and reference lists of relevant sources were manually searched. Inclusion criteria were controlled clinical trials published in English whose population were adult individuals who rinse with antimicrobial mouthwashes and that analysed changes in the oral microbiome by metataxonomy, metagenomics or phylogenetic microarray. Identified studies were screened and assessed following the PRISMA guidelines, and results were compiled into qualitative synthesis of the evidence. RESULTS: Five controlled clinical studies were included. These studies found associations between the daily use of mouthwashes and changes in the oral microbiome, but the nature of the effect varied according to the mouthwash. Chlorhexidine (CHX) rinses lowered microbial diversity. While 7-day use of CHX led to increases in the abundance of Neisseria, Streptococcus and Granulicatella and a decrease in the abundance of Actinomyces, its prolonged use led to widespread reductions in several genera and species. Cetylpyridinium chloride-containing mouthwashes specifically lowered the abundance of gingivitis-associated genera. In contrast, N-acetyl cysteine-based mouthwashes did not promote changes in the oral microbiome. CONCLUSIONS: Despite substantial heterogeneity, we found evidence to support the hypothesis that CHX and CPC mouthwashes promote changes in oral microbial structure and/or reductions in community diversity that favour the resolution of dysbiosis. However, future large population-based studies of adequate duration are needed to fully understand the extent to which antimicrobial mouthwashes modulate the microbiome.

Reliability of the Heartbeat Tracking Task to Assess Interoception.

Interoception refers to the competence in perceiving and interpreting internal sensations emerging from the body. The most common approach to assess interoception is through cardiac interoceptive tests like the heartbeat tracking task (HTT), which measures the accuracy on perceive and counting heartbeats during a period. However, the literature is scarce in providing adequate reliability evidence for this measure so that the interoception assessment may be threaten. In addition to HTT accuracy, it is possible to determine sensibility (self-reported confidence) and interoceptive awareness (correspondence between accuracy and sensibility). Thus, we measured the test-retest reliability of HTT and also investigated the behavior of HTT outcomes along the task. Therefore, 31 healthy adults (16 males) with 27.8 (9.4) years old performed two consecutive HTT interspersed by one day. Intraclass correlation coefficient (ICC), standard error of measurement (SEM) and minimal detectable difference (MD) analyzes showed 'Good' relative reliability for interoceptive accuracy (ICC = 0.880; SEM = 0.263; MD = 0.728; p < 0.001) and 'Moderate' for sensibility (ICC = 0.617; SEM = 0.648; MD = 1.797; p < 0.001) and awareness (ICC = 0.593; SEM = 0.227; MD = 0.628; p < 0.001). The absolute reliability shows low threshold values for observing true effects in HTT outcomes. The results also showed that reducing the number of HTT blocks did not impact the outcomes. The HTT showed to be reliable in determine the interoceptive competences in healthy adults.

Knowledge about recommendations for physical activity and personal practices of primary health care professionals / Conhecimento sobre as recomendações de atividades física e prática pessoal de profissionais da atenção primária em saúde

ABSTRACT Since the recommendations of moderate-to vigorous physical activity (PA) for health constitute important information to be shared in counseling practice, the present study was aimed to evaluate the level of knowledge of health professionals about the international PA recommendations for adults and elderly and to verify if there are associations between PA motivation with leisure time PA, readiness to change behavior and body mass index (BMI) of these professionals. In 2021, a questionnaire was applied remotely with health professionals from Brazilian health system. The survey had 34 participants, who answered sociodemographic and health questions, knowledge about international PA recommendations for adults and the elderly, PA duration, behavioral stage and motivations for PA practice. Of the five questions that assessed the knowledge of professionals, three had the highest prevalence of wrong answers, and professionals who have a more internal motivation to practice PA showed a significant association with reaching the minimum PA and eutrophic BMI recommendations. Professional qualification is important, together with encouragement to practice PA, through contents that consider internal motivations.

RESUMO Visto que as recomendações de atividade física (AF) moderadas e vigorosas para a saúde se constituem como uma importante informação a ser compartilhada no aconselhamento sobre AF, o presente estudo teve como objetivos avaliar o nível de conhecimento de profissionais da saúde sobre as recomendações internacionais de AF para adultos e idosos e verificar se existem associações entre a motivação para a prática de AF com o tempo de AF no lazer, o estágio de prontidão à mudança de comportamento e o índice de massa corporal (IMC) destes profissionais. Para isso, em 2021 foi aplicado, de maneira remota, um questionário com profissionais de saúde. A pesquisa contou com 34 participantes, que responderam questões sociodemográficas, de saúde, conhecimento sobre as recomendações internacionais de AF para adultos e idosos, tempo de AF, estágio comportamental e motivações para a prática de AF. Das cinco questões que avaliaram o conhecimento dos profissionais, três tiveram a maior prevalência de respostas erradas e, os profissionais que possuem uma motivação mais interna para a prática de AF apresentaram associação significativa com atingir as recomendações mínimas de AF e IMC eutrófico. É importante a qualificação profissional aliada ao incentivo à prática de AF, por meio de conteúdos que considerem motivações internas.

Positive Implicit Associations for Physical Activity Predict Physical Activity and Affective Responses During Exercise.

The purpose of this study was to investigate the relationships of implicit associations and explicit evaluations with affective responses during an aerobic exercise session, physical activity, and sedentary behavior in adults. Fifty adults (70% women; median age = 31 years; 25th, 75th percentiles: 24.50, 40.50 years old; body mass index = 25.29 ± 4.97 kg/m2) not engaged in regular physical activity completed an implicit association test and a questionnaire of explicit evaluations and wore an accelerometer for 7 days. After the 7-day period, the participants performed 30 min of moderate-intensity aerobic exercise. Every 5 min, the affective response and the perception of effort were recorded. Participants who had more positive implicit associations toward physical activity (vs. sedentary behavior) reported higher affective responses during exercise and engaged in more moderate to vigorous physical activity. Encouraging pleasant physical activity may act to partially improve future physical activity through automatic motivational processes.

Mental Fatigue Prior to Aerobic Exercise Reduces Exercise Pleasure and Negatively Affects Implicit Attitudes Toward Future Exercise.

We investigated the effects of mental fatigue (MF) on affective responses during an aerobic exercise session at moderate intensity. We submitted 12 insufficiently active adults (50% women; M age = 24.9 years, SD = 3.0; M BMI = 24.3 kg/m2; SD = 2.6) to two 30-minute pre-exercise conditions: an MF condition (Stroop Color-Word task) and a control condition (watching a documentary) prior to their performance of 20 minutes of aerobic treadmill exercise at 40-59% of heart rate reserve. The minimum washout interval between conditions was two days. Perceived MF and motivation to perform physical exercise were assessed before and after conditions with a visual analog scale of 100 mm. We assessed participants' affective and exertion responses with the Feeling Scale, Rating of Perceived Exertion (RPE) and heart rate during every two minutes of physical exercise. Implicit attitudes toward physical exercise were assessed by the Implicit Association Test before the MF and control conditions and after the physical exercise session. The participants in the MF condition reported lower pleasure (M difference = -1.57, 95% CI = -2.64 to -0.50, d = 0.93, p = .008) and higher exertion (RPE) (M difference = 1.16, 95% CI = 0.04 to 2.27, d = 0.66, p = .043) compared to those in the control condition. Participants who experienced MF also reported a more negative implicit attitude toward physical exercise than in the control condition (ß = -0.47, 95% CI= -0.73 to -0.21, d = 1.41, p < .001). While these findings should be cross-validated in subsequent research with a larger and more diverse participant sample, there appears to be value in minimizing pre-exercise mental fatigue to avoid negative MF effects on the exercisers' affective experience.

Should We Trust Perceived Effort for Loading Control and Resistance Exercise Prescription After ACL Reconstruction?

CONTEXT: The rating of perceived effort (RPE) is a common method used in clinical practice for monitoring, loading control, and resistance training prescription during rehabilitation after rupture and anterior cruciate ligament reconstruction (ACLR). It is suggested that the RPE results from the integration of the afferent feedback and corollary discharge in the motor and somatosensory cortex, and from the activation of brain areas related to emotions, affect, memory, and pain (eg, posterior cingulate cortex, precuneus, and prefrontal cortex). Recent studies have shown that rupture and ACLR induce neural adaptations in the brain commonly associated with the RPE. Therefore, we hypothesize that RPE could be affected because of neural adaptations induced by rupture and ACLR. STUDY DESIGN: Clinical review. LEVEL OF EVIDENCE: Level 5. RESULTS: RPE could be directly altered by changes in the activation of motor cortex, posterior cingulate cortex, and prefrontal cortex. These neural adaptations may be induced by indirect mechanisms, such as the afferent feedback deficit, pain, and fear of movement (kinesiophobia) that patients may feel after rupture and ACLR. CONCLUSION: Using only RPE for monitoring, loading control, and resistance training prescription in patients who had undergone ACLR could lead to under- or overdosing resistance exercise, and therefore, impair the rehabilitation process. STRENGTH-OF-RECOMMENDATION TAXONOMY: 3C.

Effects of 12 weeks of high-intensity interval, moderate-intensity continuous and self-selected intensity exercise training protocols on cognitive inhibitory control in overweight/obese adults: A randomized trial.

Growing evidence shows that aerobic exercise improves cognitive function. However, it is unclear how exercising at different exercise intensities affects cognitive inhibitory control in overweight/obese adults. Herein we compared the effects of 12 weeks of high-intensity interval training (HIIT), moderate-intensity continuous training (MICT), and self-selected intensity training (SSIT) on cognitive inhibitory control in overweight/obese adults. A total of 64 adults (59.4% women, 31.3 ± 7.1 years, 29 ± 2.5 kg/m²) were randomized into three walking/running groups: HIIT, MICT and SSIT. All groups performed three exercise sessions per week on an outdoor running track for 12 weeks. Cognitive inhibitory control was assessed at baseline and after the exercising programs using a computerized version of the Stroop Color-Words test. The HIIT and SSIT resulted in a faster Stroop effect (i.e. enhanced performance) when compared to MICT (p=.018; p= .026), however, there were no significant differences between the HIIT and SSIT groups (p> .05). The enhanced Stroop effect was correlated with increases in cardiorespiratory fitness after HIIT (r= -.521, p= .018) and decreases in body fat after MICT (r= .671, p= .001). These findings may suggest that overweight/obese adults performing exercise interventions at higher intensities or self-selected intensity may enhance their cognitive ability to inhibit automated behavioral responses.Highlights HIIT and/or SSIT are more effective than MICT in improving cognitive inhibitory control after 12-weeks in overweight/obese adults.Increases in cardiorespiratory fitness and decreases in body fat after HIIT and MICT were correlated with improvements in cognitive inhibitory control.Our study highlights the possibility of performing different exercise programs in an outdoor environment to improve cognitive function in overweight/obese adults.

A comparative evaluation of the sealing ability of two calcium silicate based sealers and a resin epoxy-based sealer through scanning electron microscopy and bond strength: an in vitro study

Aim: this study aimed to compare the sealing ability of two types of commercially available calcium silicate bioceramic based root canal sealers and a resin based root canal sealer. Methods: Twenty one single-rooted teeth were used, samples (n= 21) were randomly divided into three groups according to the sealer used (group A; ADSEAL, group B; Wellroot, group C; Ceraseal). Roots were then cleaved longitudinally in the labiolingual direction; all samples were then sectioned at three, six, and nine mm from the root tip. The penetration of sealers into the dentinal tubules was examined at 1000x with a scanning electron microscope. Data were tested for normality using Shapiro Wilk test. ANOVA test was used for analyzing normally distributed data followed by Bonferroni post hoc test for pair-wise comparison. Significance level p≤0.001. Results: groups B and C showed better sealing ability than group A in all the three sections. The coronal section showed higher sealing ability than the middle section followed by the apical section in the three tested groups. Conclusion: it can be concluded that both calcium silicate-based sealers had better sealing ability and higher bond strength than the resin epoxy- based sealer
