In a recent study, the WaveOne Gold Glider (WOGG) glide-path file system demonstrated a lower incidence of postoperative pain compared to alternative systems. The ProGlider (PG) group exhibited elevated rates of abscess formation and analgesic consumption in contrast to the other groups. Women were found to experience greater postoperative pain than men. These study findings were published in the Journal of Endodontics.

This randomized clinical trial included a total of 78 patients with asymptomatic apical periodontitis in their maxillary and mandibular molars. These patients were then randomly allocated into three groups: control group (n = 26), PG group (n = 26), and WOGG group (n = 26). Postoperative pain levels were monitored using a numerical rating scale at specific time intervals (6, 12, 18, 24, 48, and 72 hours), while the use of analgesics and abscess formation were also documented. Statistical analyses were conducted using the Mann-Whitney U, Bonferroni Dunn, Chi-square, Friedman, and Fisher exact tests.

The WOGG group demonstrated lower levels of postoperative pain at 12 and 18 hours compared to the other groups (P < .05). Women experienced higher postoperative pain scores at 6 and 24 hours in comparison to men (P < .05). Notably, the most intense postoperative pain scores were recorded at 6 hours (P < .05).

It can be concluded that the WOGG glide-path file system was linked to a reduced occurrence of postoperative pain when compared to alternative systems. In contrast to the other groups, the PG group displayed higher rates of abscess formation and analgesic consumption and women experienced greater postoperative pain than men.

A recent study showed that the use of respiratory distress symptom intervention (RDSI) has shown to be an effective and low-risk intervention in aiding the management of the respiratory distress symptom cluster in individuals diagnosed with lung cancer. This study’s findings were published in the journal, BMJ Supportive & Palliative Care.

A total of 263 patients diagnosed with lung cancer were enrolled in this clinical trial, with 132 patients assigned to receive RDSI and 131 patients assigned to receive standard care. To be eligible for the trial, participants had to self-report experiencing adverse effects in their daily lives from at least two out of the three symptoms, in any combination. The outcomes measured were the changes in each symptom within the cluster, namely Dyspnoea-12 (D-12), Functional Assessment of Chronic Illness-Fatigue, and Manchester Cough in Lung Cancer (MCLC) at the 12-week mark.

Nearly 60% of the participants reported experiencing all three symptoms at the baseline. By the end of the trial, there was a total attrition of 109 participants (41.4%). When compared to the control group, the RDSI group demonstrated a statistically significant improvement in D-12 (p=0.007) and MCLC (p<0.001). Each outcome reached the minimal clinically important difference (MCID): MCLC -5.49 (MCID >3), D-12 -4.13 (MCID >3), and FACIT-F 4.91 (MCID >4).

Thus, RDSI has proven its effectiveness and safety in supporting the management of the respiratory distress symptom cluster in patients with lung cancer. However, it is important to consider the significant attrition observed in the study while interpreting these findings.

According to a recent study, the universal adhesive with mesoporous bioactive glass (MBG) provided relief from dentin hypersensitivity, with effectiveness that is identical with or even superior to that of specific desensitizing agents. It can be utilized as an efficient in-office treatment for dentin hypersensitivity relief. This study’s findings were published in the journal, Scientific Reports.

This randomized study included 225 teeth from 39 patients to evaluate the effectiveness of a desensitizing agent with oxalate/resin polymer and a universal adhesive containing MBG for relieving dentin hypersensitivity. The assessment of efficacy was done using Schiff sensitivity score (SSS) and visual analog scale (VAS). The teeth with dentin hypersensitivity in split quadrants were treated with either MS Coat ONE or Hi-Bond Universal with MBG as the functional additive. Standardized stimulus protocols including air, cold, and acid were used for assessments at baseline, immediately after application, and at 1- and 2-week follow-ups. The primary outcome of the study was the SSS difference, whereas the VAS difference was the secondary outcome.

An instant decrease in DH was observed following exposure to air stimuli, showing a significant reduction in Group HB compared to Group MS (p = 0.017). The reduction in response to cold stimuli showed a gradual cumulative effect, consistently resulting in larger reductions in Group HB than in Group MS (p ≤ 0.037). Both groups effectively handled acidic stimuli, with no significant variances (p > 0.05). The VAS scores gradually decreased throughout the follow-up duration (p < 0.0001).

The above study showed that dentin hypersensitivity was successfully relieved by the mesoporous bioactive glass containing universal adhesive.

A recent study demonstrated that folic acid (FA) and vitamin B12 (B12) supplementation improved arsenic methylation in children, leading to a decrease in monomethyl- (MMAs) and an increase in dimethyl- (DMAs) in both blood and urine. Implementing nutritional interventions could enhance arsenic methylation and elimination in children, thereby reducing arsenic toxicity and improving their nutritional status. This study’s results were published in the Environment International journal.

This double-blind, placebo-controlled trial involved 240 participants aged 8-11 years, who were consuming water from wells with arsenic levels exceeding 50 μg/L. They were advised to switch to wells with lower arsenic levels and were randomly assigned to receive either 400 μg FA + 5 μg B12 or a placebo daily for a period of 12 weeks. Samples of urine and blood were taken at the baseline, week 1 (urine only), and week 12. Generalized estimated equation (GEE) models were utilized to evaluate the impact of the treatment on arsenic levels in both blood and urine.

At the baseline, the mean ± SD total urinary and blood arsenic levels were measured as 91.2 ± 89.5 μg/L and 5.3 ± 2.9 μg/L, respectively. After the follow-up period, there was an overall decrease of 11.7% in total blood arsenic and 17.6% in urinary arsenic. In comparison to the placebo group, the supplementation group showed a notable increase in blood DMAs concentration by of 14.0% and blood secondary methylation index (DMAs/MMAs) by 0.19 at 12 weeks. Additionally, the supplementation group had a significantly higher urinary %DMAs (1.62%) and a significantly lower urinary %MMAs (-1.10%) compared to the placebo group after 1 week. The effects of the treatment were stronger in individuals with higher baseline blood arsenic levels. These results remained consistent across both males and females, as well as participants with varying folate and B12 status at baseline.

Thus, it can be concluded that FA and B12 supplementation resulted in improved arsenic methylation in children, resulting in a reduction in MMAs and an elevation in DMAs in both blood and urine.

According to a recent study, Single Bond Universal, Xeno V+ (seventh-generation dentin bonding agents), and Bifluorid 12 exhibit equal effectiveness in reducing dentin hypersensitivity (DH), with no clear superiority observed over a one-month period. These findings underscore the potential of fluoride varnishes as a cost-effective and less technique-sensitive treatment option for DH. This study’s results were published in the BMC Oral Health.

In this parallel-group, single-center, double-blind, controlled randomized clinical trial, a total of 105 patients with DH were included. The patients were divided into three groups: one group received Single Bond Universal by 3 M ESPE, another group received Xeno-V+ by Dentsply, and the control group received fluoride varnish (Bifluorid 12 by Voco). This study assessed the Discomfort Interval Scale scores and Schiff Cold Air Sensitivity Scale scores at baseline, immediately after the treatment, after 1 week, and after 1 month.

Treatment with all the materials demonstrated a significant reduction in discomfort and sensitivity (DIS scores p-value 0.01) observed immediately after one week and sustained over one month compared to baseline scores. None of the materials showed superiority during the one-month observation period. The study also provided insights into dental hygiene practices, indicating that the majority of participants used a toothbrush. Cold stimuli were identified as the most prevalent cause of sensitivity.

The above study demonstrated that Single Bond Universal, Xeno V+, and Bifluorid 12 are equally effective in reducing dentin hypersensitivity for one month. These results underscore the potential of fluoride varnishes as a cost-effective and less technique-sensitive treatment option for DH.

According to a recent study, thymus vulgaris (TV) syrup may be an effective adjunctive therapy in the management of asthma exacerbations in children. This study’s results were published in the journal, Allergologia et Immunopathologia.

In this triple blinded, randomized clinical trial, a total of 60 children aged between 5 and 12, who were experiencing asthma exacerbations, were divided into two groups. The intervention group, consisting of 30 children, received TV powder in syrup form at a dosage of 20 mg/kg every 8 hours, in addition to their regular medical treatment, for a duration of one week. On the other hand, the control group, also comprising 30 children, received a placebo syrup along with their regular medical treatment. At the end of the week, clinical and laboratory symptoms, as well as spirometry data, were recorded again for both groups.

Following the intervention, there was a decrease in activity-induced cough, with a statistically significant difference observed between the two groups (p = 0.042). Analysis of spirometry data revealed a significant variance in forced expiratory volume in 1 second (FEV1) between the two groups post-intervention (p = 0.048).

Thus, it can be concluded that TV syrup may be a beneficial supplementary treatment in the control of asthma exacerbations among children.

A recent study has shown that the use of oral adhesive bandages were more effective compared to cotton balls and gauze, leading to better hemostatic and comfort outcomes for extraction wounds. This study’s findings were published in the journal, Clinical Oral Investigations.

This randomized controlled clinical study involved 120 patients who were randomly allocated to either the study group or the control group. The control group used gauze and cotton balls, while the study group received oral adhesive bandages for wound dressing. Comfort, hemorrhage, and healing levels were assessed at 1 hour, 24 hours, and 7 days postoperatively. The duration of adhesion for the oral adhesive bandages was also monitored.

The oral adhesive bandages exhibited an average adhesion time of 26.6 hours. The hemostatic levels in the oral adhesive bandage group were significantly higher than those in the control group at both postoperative 1 and 24 hours. Additionally, the oral adhesive bandage group reported significantly higher comfort scores compared to the control group. Both groups demonstrated similar levels of healing and side effects, with a slightly higher mean score for wound healing observed in the oral adhesive bandage group.

The above study demonstrated that oral adhesive bandages are more effective than gauze and cotton balls, resulting in superior hemostatic and comfort outcomes for extraction wounds.

According to a recent study, erenumab (140 mg) demonstrated long-lasting effectiveness over a period of 3 years in individuals with episodic migraine (EM) who had 2-4 unsuccessful attempts at preventive treatment. This study’s findings were published in the journal, Neurology.

Following the 12-week double-blind treatment phase (DBTP) of the LIBERTY study, 240/246 (97.6%) participants entered the Open-Label Extension Phase (OLEP) and received a monthly dosage of 140 mg of erenumab for a period of 3 years. The main outcomes of this study included determining the percentage of participants who achieved a reduction of 50% or more in monthly migraine days (MMDs), analyzing the mean change in MMDs from the baseline, and assessing the tolerability and safety of the treatment.

At week 168, a total of 79 out of 151 participants (52.3%) in the overall population, who had valid data points, achieved a reduction of at least 50% in MMDs and were considered responders. In the continuous erenumab group, 35 out of 117 participants (29.9%) were ≥50% responders at week 12 of the double-blind treatment period, and 26 out of 35 (74.3%) remained responders in at least half of the visits during the open-label extension period. Among the 82 out of 117 participants (70.1%) in the continuous erenumab group who did not achieve responder status at week 12, 17 out of 82 (20.7%) converted to ≥50% responders in at least half of the open-label extension phase visits. In the placebo-erenumab group, out of the 103 out of 120 participants (85.8%) who did not achieve responder status at week 12, 42 out of 103 (40.8%) converted to ≥50% responders in at least half of the open-label extension phase visits after switching to erenumab treatment. The mean (SD) change in MMD from baseline over 3 years showed a sustained improvement of -4.4 [3.9] days at week 168. The safety and tolerability profile remained consistent with previous studies.

The above study demonstrated that in individuals with episodic migraine (EM) who had previously encountered 2-4 unsuccessful preventive treatment attempts experienced long-lasting efficacy with erenumab (140 mg) over a period of 3 years.
