Effect of a novel low-concentration hydrogen peroxide bleaching gel containing nano-sized sodium trimetaphosphate and fluoride.

OBJECTIVES: To evaluate in vitro the effects of nano-sized sodium trimetaphosphate (TMPnano) and sodium fluoride (F) added to a 17.5 % hydrogen peroxide (H2O2) bleaching gel on the color change, enamel mechanical and morphological properties, and H2O2 transamelodentinal diffusion. MATERIALS AND METHODS: Bovine enamel/dentin discs (n = 180) were divided according to the bleaching gel: 17.5 % H2O2 (17.5 % HP); 17.5 % H2O2 + 0.1 % F (HP/F); 17.5 % H2O2 + 1 % TMPnano (HP/TMPnano); 17.5 % H2O2 + 0.1 % F + 1 % TMPnano (HP/F/TMPnano) and 35 % H2O2 (35 % HP). The gels were applied for 40 min on three sessions, each session spaced 7 days apart. The total color change (ΔE*ab) according to the Commission Internationale de l'Eclairage (CIE) L*a*b* color change measured by CIEDE2000 (ΔE00), whitening index (ΔWID), surface hardness (SH), surface roughness (Ra), cross-sectional hardness (ΔKHN), and transamelodentinal diffusion were assessed. Enamel surfaces were examined using Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray (EDS) analysis. The data were analyzed using ANOVA, followed by the Student-Newman-Keuls test (p < 0.05). RESULTS: ΔE*ab, ΔE00, and ΔWID values were comparable among the gels that produced a bleaching effect post-treatment (p < 0.001). The HP/F/TMPnano group exhibited lower mineral loss (SH and ΔKHN), Ra, and H2O2 diffusion compared to the 17.5 % HP and 35 % HP groups, which had the highest values (p < 0.001). SEM/EDS analysis revealed surface changes in all bleached groups, though these changes were less pronounced with F/TMPnano. CONCLUSIONS: The 17.5 % HP gel containing F/TMPnano maintains the bleaching effect while reducing enamel demineralization, roughness, H2O2 diffusion, and enamel morphological changes. CLINICAL RELEVANCE: Low-Concentration H2O2 bleaching gel containing F/TMPnano can be used as a novel approach to enhance safety and maintain the performance of aesthetic effects.

Cardiovascular and Renal Effects Induced by Alpha-Lipoic Acid Treatment in Two-Kidney-One-Clip Hypertensive Rats.

α-Lipoic acid (LA) is an antioxidant of endogenous production, also obtained exogenously. Oxidative stress is closely associated with hypertension, which causes kidney injury and endothelial dysfunction. Here, we evaluated the cardiovascular and renal effects of LA in the two-kidney-one-clip (2K1C) hypertension model. The rats were divided into four groups: Sham surgery (Sham), the two-kidneys-one-clip (2K1C) group, and groups treated with LA for 14 days (Sham-LA and 2K1C-LA). No changes were observed in the pattern of food, water intake, and urinary volume. The left/right kidney weight LKw/RKw ratio was significantly higher in 2K1C animals. LA treatment did not reverse the increase in cardiac mass. In relation to vascular reactivity, there was an increase in the potency of phenylephrine (PHE) curve in the hypertensive animals treated with LA compared to the 2K1C group and also compared to the Sham group. Vasorelaxation induced by acetylcholine (Ach) and sodium nitroprusside (SNP) were not improved by treatment with LA. Urea and creatinine levels were not altered by the LA treatment. In conclusion, the morphological changes in the aorta and heart were not reversed; however, the treatment with LA mitigated the contraction increase induced by the 2K1C hypertension.

Antimicrobial photodynamic therapy in the nonsurgical treatment of periodontitis in patients with HIV infection: a systematic review and meta-analysis.

The aim of this systematic review and meta-analysis (SRM) was to evaluate the effectiveness of the adjunctive use of antimicrobial photodynamic therapy (aPDT) in non-surgical periodontal treatment (NSPT) in subjects with Human Immunodeficiency Virus (HIV) and periodontitis. This SRM was registered in PROSPERO (CRD42023410180) and followed the guidelines of PRISMA 2020. Searches were performed in different electronic databases. Risk of bias was performed using the Cochrane Risk of Bias tool (RoB 2.0) for randomized clinical trials (RCT). Meta-analysis was performed using Rev Man software. The mean difference (MD) measure of effect was calculated, the random effect model was applied with a 95% confidence interval, and heterogeneity was tested by the I2 index. The certainty of the evidence was rated using GRADE. A total of 1118 records were screened, and four studies were included. There was a greater reduction in the microbial load of periodontopathogens after NSPT with aPDT. Meta-analysis showed that probing depth (post 3 and 6 months) and clinical attachment loss (post 6 months) were lower for the aPDT-treated group than the NSPT alone: MD -0.39 [-0.74; -0.05], p = 0.02; MD -0.70 [-0.99; -0.41], p < 0.0001; MD -0.84 [-1,34; -0.34], p = 0.0001, respectively. Overall, the studies had a low risk of bias and, the certainty of evidence was rated as moderate. It is suggested that aPDT is a promising adjuvant therapy, showing efficacy in the reduction of the microbial load and in some clinical parameters of individuals with periodontitis and HIV.

CONCLUSIONS: the plurality of functions in the same device reflects the search for optimizing resources and the concern with comprehensive care.

Effects of whey protein supplementation on gut microbiota of Wistar rats with valproic acid-induced autism symptoms.

Aim: To evaluate the effects of whey protein (WP) supplementation (1.24 mg/g, 24 days) in rats with autism spectrum disorder (ASD) induced by valproic acid (400 mg/kg, single dose). Materials & methods: Wistar rats (14 days old) were divided into four groups: control, ASD, ASD plus WP and WP. Results: WP increased bacterial diversity and the number of colonies. Bacteria from the Firmicutes phylum were predominantly found in the supplemented groups (p < 0.05). WP also improved the animals' memory in the Y-maze test and decreased the time that male animals spent in the 'solitary chamber' (p < 0.05). Conclusion: WP supplementation positively influenced gut microbiota, along with memory.

Thousands of bacteria live in the human intestine. These bacteria help with many functions in the body and are so important that they can communicate with the brain. When the types and abundance of these bacteria change, brain activity can also change. This may be the case in some children with autism spectrum disorder (ASD), who may have an increase in harmful types of bacteria and a decrease in beneficial types of bacteria in the gut. Whey protein is a commonly used protein supplement for muscle growth. However, many studies have shown its benefits for gut bacteria. The authors investigated the effects of whey protein in animals with symptoms of ASD and showed that supplementation with whey protein increased the number of beneficial bacteria. In addition, the rats given whey protein had better memory. ASD-induced rats were less sociable, spending more time by themselves. However, male animals treated with whey protein spent less time alone. Supplementation with whey protein was beneficial for gut bacteria and memory in rats.

Effects of Beetroot-Based Supplements on Muscular Endurance and Strength in Healthy Male Individuals: A Systematic Review and Meta-Analysis.

The aim of this study was to systematically review the current literature and analyze the effects of beetroot-based supplements (BRS) on muscular performance. Randomized controlled trials that assessed the acute or short-term effects of BRS administration on muscular endurance and/or strength in healthy male individuals were retrieved from PubMed, EMBASE, CENTRAL, and Web of Science databases from inception to February 20th, 2023. In addition, we also searched preprint papers in medRxiv.org, bibRxiv.org; thesis and dissertations included in oatd.org; and clinical trials published in ClinicalTrials.gov. Data extraction, risk of bias, and study quality were assessed by 2 authors. Meta-analyses and subgroup analyses of standardized mean differences (SMD) were performed using a random-effects model. A total of 1486 records were identified in the databases and 2 were obtained by manual search in the reference list. Of those, 27 studies attended eligibility criteria and composed this systematic review. BRS administration resulted in a positive effect on muscular endurance (SMD: 0.31; 95% confidence interval (CI): 0.10 to 0.51; p < 0.01; n = 16 studies). There was an overall significative effect for muscular strength (SMD: 0.26; 95% CI: 0.03 to 0.48; p < 0.05; n = 18 studies), but a subgroup analysis showed that significant effects were found when strength was measured in a fatigued (SMD: 0.64; 95% CI: 0.25 to 1.03; p < 0.01), but not resting state. BRS administration have a small ergogenic effect on muscular endurance and attenuate the decline in muscular strength in a fatigued state in healthy male individuals.

Beetroot-based supplements can improve muscular endurance and attenuates the decline in muscular strength. These effects are attributed to the inorganic nitrate contained in these products, which ranged from 316­985 mg/day, ingested 2­3 hours before exercise.Beetroot-based supplements administration can generate a modest increase in the number of repetitions performed to failure or in exercise time to exhaustion, which may contribute to the performance and optimization of the results of people involved in isotonic exercises (e.g., resistance training).Beetroot-based supplements ingestion can improve muscular strength, particularly it aids in the recovery of muscular strength after a fatiguing task.

Effects of Water Deficit on Growth and Productivity in Tomato Crops Irrigated with Water Treated with Very Low-Frequency Electromagnetic Resonance Fields.

The tomato crop is very sensitive to stress conditions. A water deficit is defined as when precipitation is less than the evapotranspiration (ETc) of the crop in a given period, and in this scenario of climate change, it is identified as responsible for global productivity losses. The use of potential technologies for better irrigation management, such as electromagnetically treated water, remains controversial. Thus, the objective of the present work was to investigate the effects of very low-frequency electromagnetic resonance field treatment on water for tomato crops submitted to different irrigation rates. For this, an experiment was carried out under controlled conditions with different types of water: electromagnetically treated water (WTVLF) and untreated water (UNW), as well as four water replacement rates: 40, 60, 80, and 100% ETc. The electromagnetic treatment of the water was carried out using the commercial equipment AQUA4D®. The experiment was carried out in pots with five replications per treatment. Lower activity of SOD, POD, CAT, and APX enzymes was observed in plants irrigated with water treated with very low-frequency electromagnetic resonance fields (WTVLF), indicating less oxidative stress caused by water deficit. Water deficit reduced chlorophyll content, but the effects were less harmful with WTVLF water. The water deficit resulted in less accumulation of dry matter and less productivity in a linear relationship. However, plants irrigated with WTVLF showed increments of about 20% in dry matter accumulation and 20% in fruit production concerning plants irrigated with untreated water, independent of the irrigation rates. We can conclude that irrigation with WTVLF can be a solution to reduce the damage caused by water deficits and increase the productivity of tomato crops.

Influence of bleaching gels formulated with nano-sized sodium trimetaphosphate and fluoride on the physicochemical, mechanical, and morphological properties of dental enamel.

OBJECTIVES: To evaluate in vitro the effects of sodium fluoride (F) and nano-sized sodium trimetaphosphate (TMPnano) added to a 35% hydrogen peroxide (H2O2) bleaching gel on the color alteration, enamel mechanical and morphological properties, and H2O2 transamelodentinal diffusion. MATERIALS AND METHODS: Bovine enamel/dentin discs (n = 180) were divided according to the bleaching gel: 35% H2O2 (HP); 35% H2O2 + 0.1% F (HP/F); 35% H2O2 + 1% TMPnano (HP/TMPnano); 35% H2O2 + 0.1% F + 1% TMPnano (HP/F/TMPnano) and 35% H2O2 + 2% calcium gluconate (HP/Ca). The gels were applied 3 times by 40 min; once each 7-day. The Commission Internationale de l'Eclairage (CIE) L*a*b* total color alteration (ΔE), color alteration by CIEDE2000 (ΔE00), whitening index (ΔWID), surface (SH) and cross-sectional hardness (ΔKHN), surface roughness (Ra), and transamelodentinal diffusion were determined. Enamel surfaces were evaluated by Scanning Electron Microscopy (SEM) and X-ray Dispersive Energy (EDX). Data were submitted to ANOVA, followed by the Student-Newman-Keuls test (p <0.05). RESULTS: ΔE, ΔE00, and ΔWID were similar among the gels that promoted a bleaching effect after treatment (p <0.001). Mineral loss (SH and ΔKHN), Ra, and H2O2 diffusion were lower for HP/F/TMPnano; the HP and HP/Ca groups presented the highest values (p <0.001). For SEM/EDX, surface changes were observed in all bleached groups, but less intense with TMPnano. CONCLUSIONS: Gels containing F/TMPnano do not interfere with the bleaching effect and reduce enamel demineralization, roughness, H2O2 diffusion, and morphological changes. CLINICAL RELEVANCE: Whitening gels containing F/TMPnano can be used as a new strategy to increase safety and maintain clinical performance.

Serum il-18 and rs187238 single nucleotide polymorphism are associated with high-density lipoprotein changes in covid-19 outpatients.

AIM: COVID-19 is an inflammatory disease and its prognosis is associated with cardiovascular risk, which can be associated with changes in lipoprotein metabolism. The single nucleotide polymorphism (SNP) rs187238 of Interleukin (IL)-18 is extensively reported in association with worsening inflammatory and cardiovascular disease (CVD). This study evaluated the association of IL-18 levels and its SNP rs187238 with lipoprotein profile changes in COVID-19 outpatients. METHODS: Observational, analytical, cross-sectional study that evaluated 250 patients with respiratory syndrome, 36% (n = 90) with COVID-19. Serum total cholesterol (TC), high-density lipoprotein cholesterol (HDL-c), low-density lipoprotein cholesterol (LDL-c), triglycerides (TG), apolipoproteins A-I and B (Apo A-I and Apo B) and IL-18 levels were determined. Polymorphism genotyping was done by real-time polymerase chain reaction (qPCR). The significance level was p < 0.05. RESULTS: Patients with COVID-19 showed a reduction in TC and HDL-c, without difference in IL-18. HDL-c and LDL-c had a high frequency outside the reference values. There was a negative correlation of IL-18 with HDL-c and a positive correlation with Apo B/Apo A-I ratio. The frequencies of the C (wild) and G (polymorphic) alleles between patients with and without COVID-19 followed the Hardy-Weinberg equilibrium. However, COVID-19 was associated with reduced HDL-c and Apo A-I values in patients with the CC genotype. CONCLUSION: IL-18 levels and its SNP rs187238 were associated with decreased HDL-c and Apo A-I in COVID-19 outpatients.

Analysis of patent records related to the prevention and signaling of falls in Brazil.

OBJECTIVE: To analyze patent records aimed at preventing and signaling falls in a Brazilian database. METHOD: Electronic documentary research carried out in the database of the Instituto Nacional da Propriedade Industrial using the word "fall" in the search resource. Patent records related to the prevention and signaling of falls at home and in care environment applied from 2000 to 2021 were included. Tabulated data were evaluated using absolute/relative frequencies. RESULTS: From the 45 patents, 91% were published starting from 2011, with an average of 1214 days between application and publication, 11% of applicants were from public universities and 9% of the inventors were nurses, physician or physical therapists. CONCLUSION: There was a delay in the publication of the patents and small participation of researchers linked to the academic area and health professionals, revealing the need to equip universities and health services in order to guarantee the development of innovations.

Murici (Byrsonima crassifolia (L.) Kunth and verbascifolia (L.)) and Tapereba (Spondias mombin) Improve Hepatic and Inflammatory Biomarkers in High-Fat-Diet Rats.

The present study investigated the effects of murici and tapereba on improving hepatic and inflammatory biomarkers in high-fat-diet rats. Female Wistar rats were divided into five groups (n = 10/group): control (CON), high-fat diet (HF), murici drink + high-fat diet (Mu-HF), tapereba drink + high-fat diet (Tap-HF), and murici and tapereba blend drink + high-fat diet (MT-HF). Drinks were offered daily for 60 days, following which body and liver weights, hepatosomatic indexes, serum parameters, inflammatory profile, and antioxidant activity (DPPH and ORAC) were analyzed. The cell death of hepatic cells was evaluated using flow cytometry. It was observed that weight gain was similar among the groups, while glycemia was lower in the MT-HF group. A high-fat diet increased the concentration of cholesterol total, ALT, IL-1ß (in plasma and liver), and TNF-α (in the liver), and this was reduced by treatment with the fruit-based beverages. The other evaluated parameters showed no statistically significant difference. Compared to the CON and HF groups, the groups that received the drinks had higher cellular antioxidant activity and reduced oxidative stress, lipid oxidation, and development of pro-inflammatory cytokines, such as IL-1ß. A high-fat diet induced higher cell death in hepatic tissue, which was prevented by the murici, tapereba, and the fruit-blend drinks. The consumption of murici, tapereba, and fruit-blend-based beverages showed beneficial effects on liver metabolism; therefore, they may serve as a nutritional approach for preventing and treating non-alcoholic liver disease.

The overall CVI values of the 39-item instrument were: Clarity (0.91) and Relevance (0.95). The final version was obtained through 19 knowledge, 10 attitude, and 10 practice questions on caries, diet, oral hygiene, fluoride, breastfeeding, artificial feeding, milk teeth, and the need to take the baby to the dentist. The instrument produced can be used because it has the potential for use depending on the more global assessment of its psychometric properties.

Association of serum lipoproteins and inflammatory parameters derived from the blood test with renal function in COVID-19 outpatients

Abstract Changes in lipoprotein metabolism are among the main causes of hemodynamic impairment in renal function. COVID-19 is an multisystemic inflammatory disease, aggravating this situation. This cross-sectional study investigated the relationship of serum lipoprotein profile with inflammatory parameters and renal function in 95 COVID-19 outpatients in comparison with 173 with flu-like symptoms. Serum samples were collected for the determination of total cholesterol and fractions, apolipoproteins (Apo A-I and Apo B), urea (sUr) and creatinine (sCr). The glomerular filtration rate (eGFR) was calculated. Neutrophil/lymphocyte (NLR) and platelet/lymphocyte (PLR) ratios were calculated as inflammatory parameters derived from the blood tests. COVID-19 patients presented lower high-density lipoprotein cholesterol (HDL-c) (47.90 ± 1.543 vs. 51.40 ± 0.992) and higher PLR (190.9 ± 9.410 vs. 137.6 ± 5.534) and NLR (3.40 ± 0.22 vs. 2.80 ± 0.15). Both NLR and PLR correlated with each other (r = 0.639). Furthermore, the Apo B/Apo A-I ratio was correlated with PLR (r = 0.5818) and eGFR (r = -0.2630). COVID-19 patients classified as at high risk of developing acute myocardial infarction based on the Apo B/ Apo A-I ratio had higher values for sUr/sCr. Thus, serum apolipoproteins, PLR, and NLR could be related to renal dysfunction in COVID-19.
