Analysis of Chlorhexidine Modified Cement in Orthodontic Patients: A Double-Blinded, Randomized, Controlled Trial

Abstract Objectives The aim of this study was to evaluate the microbiological and mechanical properties of glass ionomer cement (GIC) modified by chlorhexidine (CLX) for the purpose of cementing bands to the teeth of orthodontic patients. Materials and Methods Ten patients, between the ages of 19 and 33 years, in the initial stage of orthodontic treatment, were randomly designated to two groups using the split-mouth design (n = 10). One group (GICEX) had bands cemented with GIC modified by CLX and a Control group (GIC), evaluated at time intervals before (T0), 3 months (T3), and 6 months (T6) after cementation. Total microbiological counts were performed, and color stability of tooth enamel, salivary pH, and the adhesive remnant index (ARI) were evaluated. Statistical Analysis The Friedman and Dunn’s tests, Mann–Whitney, one-way analysis of variance, and Tukey, and paired and non-paired t-tests (p< 0.05) were used. Results In T3, there was evidence of significant reduction in the quantity of colony forming unit (CFU) in GICEX group in comparison with the Control (p = 0.041). In T6, the quantity of CFU was similar to the quantity in T3 and significantly different to control (p = 0.045); Control group demonstrated a similar quantity of CFU between the experimental time intervals (p = 0.066). Salivary pH demonstrated significant difference only between the time intervals T0 and T6 (p = 0.022). The tooth enamel color (p = 0.366) and ARI (p = 0.343) values demonstrated no significant changes. Conclusion The incorporation of CLX into GIC demonstrated effective antibacterial action, allowed a good bond of the cement to the enamel, a high rate of survival of the bands, did not change the color of the tooth enamel, and maintained the salivary pH at physiological levels.

Pendahuluan: Derajat keasaman (pH) saliva merupakan faktor kunci utama keseimbangan demineralisasi dan remineralisasi gigi. Demineralisasi email terjadi pada keadaan pH <5,5 dan terjadi dalam waktu beberapa menit setelah asupan sukrosa. Saliva memiliki peran signifikan dalam proses meningkatkan pH rongga mulut sehubungan dengan kemampuan buffering, yaitu kandungan bikarbonat yang dapat menetralkan pH sehingga mencegah enamel gigi dari demineralisasi. Tujuan penelitian ini untuk mengukur atau menilai peranan keju Brie dalam menaikan pH saliva. Metode: Penelitian ini merupakan eksperimental semu bersifat komparatif. Jumlah subjek penelitian adalah 32 orang yang dibagi menjadi kelompok perlakuan, yaitu mengonsumsi keju Brie dan kelompok kontrol, yaitu tidak mengonsumsi keju Brie. Subjek penelitian diukur nilai pH saliva awal dan akhir menggunakan pH test strip. Hasil: Rerata selisih nilai pH awal dan akhir pada kelompok perlakuan adalah sebesar 0,48 dan pada kelompok kontrol adalah sebesar -0,29. Rerata selisih pH saliva pada kelompok perlakuan, yaitu mengonsumsi keju Brie, lebih besar dibandingkan dengan kelompok kontrol, dengan perbedaan yang signifikan (p<0,05). Simpulan: Mengonsumsi keju Brie efektif dalam meningkatkan pH saliva.Kata kunci: Efektivitas, keju Brie, pH saliva ABSTRACTIntroduction: Salivary acidity degree (pH) is the main key factor in the balance of tooth demineralisation and remineralisation. Enamel demineralisation occurs at the pH < 5.5 and occurs within minutes after sucrose intake. Saliva has a significant role in the process of pH increase in the oral cavity due to the buffering ability, which is the bicarbonate content which able to neutralise the pH value to prevent tooth enamel demineralisation. The purpose of this study was to measure or assess the effect of Brie cheese consumption in raising the salivary pH. Methods: This study is a quasi-experimental comparative. The number of research subjects was 32 people who were divided into treatment groups which consumed Brie cheese, and the control group which did not consume Brie cheese. Each research subject was measured the initial and final salivary pH values using a pH test strip. Results: The average difference in the initial and final pH values of the treatment group was 0.48, and in the control group was -0.29. The average difference of the salivary pH in the treatment group, which was consuming Brie cheese, was higher than the control group, with a significant difference (p < 0.05). Conclusion: Consuming Brie cheese is effective in increasing the salivary pH.Keywords: Effectiveness, Brie cheese, salivary pH

The Impact

Scientific research into the reduction of stigmatization, particularly related to specific problems such as Obsessive-Compulsive Disorder (OCD), is scarce. In the present study, we examine the impact of a video-based antistigma intervention program for OCD in a pretest-posttest control group research. After being randomly assigned to either an intervention (n= 101) or control group (n= 96), the participants reported their attitudes on a hypothetical case vignette before and after OCD vs. Multiple Sclerosis (MS) videos, and again six months later as a follow up assessment. The mixed design analyses for the group comparisons indicated that although there was no significant difference in the measures of the control group, the participants watching the anti-stigma OCD video, in which the focus was psychoeducation and interaction strategies, reported significantly lower scores on social distances and negative beliefs for the case vignettes they read, and this difference was maintained six months later. Then, the present results indicate the effectiveness of our anti-stigma intervention program for OCD. Interventions to reduce stigmatization can also be viewed as effective tools for changing the attitudes of people toward OCD, although further research and applications are needed related to specific disorders if a longlasting impact is to be achieved.

Mother-infant attachment is an intimate, lasting and satisfying relationship that leads to better cognitive, emotional and social growth of the infant. The aim of this study was to determine the effects of breastfeeding training by role-play on mother-infant attachment behaviours. This research was a randomised clinical trial (parallel design). Inclusion criteria were: no history of mental disorders; ability to read and write the Persian language to complete the questionnaire; no history of drug and tobacco intake in primigravida women. The sample comprised 100 pregnant women (in 2 groups), selected through simple random sampling at healthcare centres. The researcher reviewed prenatal care registries of selected healthcare centres and extracted the names of pregnant women in their early third trimester. The data were imported into randomisation software. The control group received routine breastfeeding training, while the intervention group received routine training together with training through role-play. The data collection tool was the Maternal Behaviour Inventory Questionnaire. Consequently 75 samples were analysed in SPSS16. Independent t-tests and chi-square tests were used to examine the difference between the two groups. Results showed that the mean score of mother-infant attachment one week after delivery was significantly higher in the intervention group in comparison to that in the control group (p<0.001). No significant difference was observed between the two groups in maternal age, age of marriage, neonatal gender, maternal employment and education, number of parity, and number of abortions (P>0.05). Since breastfeeding training through role-play could affect mother-infant attachment, it is suggested that this type of training should be provided for pregnant women to promote mother-infant attachment and exclusive breastfeeding.

Background: Pain control is considered as the key issue in modern midwifery. Along with medical painkillers, reflexology is viewed as a non-medical and noninvasive method. Hence, we aimed to investigate the effect of reflexology on the intensity of pain and length of labor. Materials and Methods: In this clinical trial, participants included 240 Iranian primiparous women with term and singleton pregnancy. Having a 3-4 cm cervical dilatation once they visited the hospital. Through a convenient sampling method, they were selected and then randomly divided into two groups. In the intervention group, reflexology was performed, and the intensity of pain during the active phase of labor along with the length of labor in the active phase was measured by visual analog scale (VAS) and compared with the control group. Data were analyzed using descriptive statistics, t-test, and Mann-Whitney U-test. Result: Data analysis showed a statistically significant difference between the intensity of pain in the 5-7 and 8-10 cm dilatation in the two groups (P=0.01). Moreover, the labor length in the active phase was found to be significantly shorter in the intervention group (P<0.001). Conclusion: It appears that reflexology can lead to a reduction in the pain and length of labor. Therefore, through instructing this technique, a goal of midwifery, which is reducing labor pain and its length can be achieved. Keywords: Reflexology, Labor Pain, Labor Length, Primiparous Women

BACKGROUND Cancer is a chronic disease with an incident worldwide had been 24.5 million and 9.6 million deaths in 2017. Lung and colorectal cancer are the most common cancer for both sexes and according to national and international recommendations platinum-based chemotherapy is the reference adjuvant treatment. This chemotherapy can be moderately to highly emetogenic. Despite antiemetic therapy, chemotherapy-induced nausea and vomiting may persist. Moreover, cancer patient are increasingly interested in alternative and complementary medicines and express the desire that non-pharmacological treatments be used in hospitals. Among alternative and complementary medicines, foot reflexology decreases significantly the severity of chemotherapy-induced nausea and vomiting in breast cancer patients. OBJECTIVE The primary objective of the present study was to assess the benefits of foot reflexology as a complement to conventional treatments on severity of acute chemotherapy-induced nausea and vomiting in digestive or lung cancer patients. The secondary objectives assessed were the frequency and severity of delayed chemotherapy-induced nausea and vomiting, quality of life, anxiety, and self-esteem. METHODS The present study was conducted between April 2018 and April 2020 in French University Hospital. This is an open-label randomized controlled trial. Participants are randomized into two groups: 40 to interventional group (conventional care with foot reflexology) and 40 to control group (conventional care without foot reflexology). Foot reflexology sessions (30 minutes) are performed on an outpatient or inpatient. Eligible participants are patients with a lung or digestive cancer with indication for platinum-based chemotherapy. RESULTS The severity of acute nausea and vomiting was assessed with a visual analogue scale during the second cycle of chemotherapy. A significant increase of at least 2 points was observed for control group (20.6%, P = 0.01). Across all cycle, the foot reflexology group showed a trend towards less frequent delayed nausea (P=0.28), a significantly less frequent consumption of antiemetic drugs (P=0.04), and no significant difference for vomiting (P=0.99); there was a trend towards a perception of stronger severity for delayed nausea in the control group (P=0.39). According to quality of life and anxiety, there was no significant difference between the interventional group and the control group (P=0.32 and P=0.53 respectively). CONCLUSIONS In conclusion, the present study results indicated that foot reflexology decreased significantly the severity of acute nausea and consumption of antiemetic drugs in lung and digestive cancer patients. No side effects from foot reflexology have been noted. In order to better respond to a desire of patients for non-pharmacological treatments and CAMs to be used in hospitals to improve their care, the results of this study showed that foot reflexology seems to be a promising complement to conventional antiemetic drugs. To assess the performance of this intervention in routine practice, a larger study with several health care centers would be relevant with a cluster RCT.

Background and aim: Hypotension during cesarean section (CS) under spinal anesthesia has been a subject of scientific study for more than 50 years and the search for the most effective strategy to achieve hemodynamic stability remains challenging. Aim: The study was carried out to apply leg wrapping technique for the prevention of spinal-induced hypotension (SIH) during CS.Methods: Randomized Controlled Trial design was utilized at cesarean delivery operating room Mansoura General Hospital in El-Mansoura City during the period from May 2018 to November 2018. A purposive sample of 88 pregnant women, assigned randomly to an intervention group (n = 44) in which their legs wrapped with elastic crepe bandage and control group (n = 44) in which no wrapping was done. Data collected for maternal, neonatal hemodynamic and signs of hypotension, the feasibility of application and cost analysis.Results: There was a statistically significant difference in the incidence of SIH and Ephedrine use among both groups (18.20% in leg wrapping group whereas 75% in control group). In addition, neonatal acidosis and NICU admission were less among leg wrapping group (11.40%, 9.10% respectively). Economically, leg wrapping technique was cost effective compared to the cost of the hospital regimen for treating SIH and admission to (NICU).Conclusion and recommendations: Leg wrapping technique was cost effective and an efficient method for decreasing SIH, neonatal acidosis and Ephedrine administration. It is recommended to apply leg wrapping technique in maternal hospitals' protocol of care for decreasing SIH during CS.

Objective Plasma is formed by creating a high-density energy field within an electrically conductive fluid such as saline. Sometimes ablated bits of tissue get stuck between the electrodes of the wand, obstructing the suction channel. The purpose of this study is to investigate the effect of cooling the irrigating saline during ablation of the hypertrophied tongue base in patients with obstructive sleep apnea. Study Design Prospective randomized controlled trial. Setting An otorhinolaryngology department in Main University hospitals. Methods Sixty adult patients with obstructive sleep apnea and tongue base hypertrophy underwent tongue base ablation surgery. Patients were randomly divided into 2 groups of 30 patients each: cooled saline and room temperature saline. The Coblation wand used was the EVac 70 Xtra HP (Smith & Nephew). Results In this study, a significant difference in operative time (mean ± SD) was seen between groups: 21.2 ± 5.5 minutes in the cold group and 47 ± 9.5 minutes in the control group ( P = .001). The wands in the cold group did not obstruct, while all the wands in the control group were obstructed by tissue clogs with variable degrees, hence wasting more time to clean the wands’ tips. Conclusion Cooling the irrigating saline overcame the problem of wand clogs, and the wand tip did not occlude at all during the procedures, thus saving time lost in wand cleaning and demonstrating a faster and safer surgical procedure. Further studies are needed to identify the hemostatic effect of the cooled saline over the regular one.

Abstract Background A peer-led exercise program is one way to empower people sharing similar characteristics to encourage others to be active, but there is a lack of evidence that these programs have physical function and other benefits when delivered to ageing adults. Methods This randomized controlled trial lasting 12 weeks proposed an exercise peer-led program offered to 31 adults aged 50 and above, twice a week, by a trained leader of the same age from March to May 2019. The program was offered for free with limited space and equipment. Valid tests of physical function (e.g., 30-s chair stand, 6-min walk test) were used to assess the functional benefits. Psychosocial outcomes were assessed using self-reported questionnaires and metabolic outcomes via a fasted blood draw. Results A significant difference was found between pre-and post-values in most physical function tests in the intervention group (all p < 0.05). When adjusted for potential confounders, the intervention group was significantly associated with a more significant improvement on the chair stand test (ß = .26; p < 0.001; r2 = 0.26), the arm curl (ß = .29; p < 0.001; r2 = 0.49), as well as the 6-min walk test (ß = -.14; p < 0.001; r2 = 0.62) compared with the control group. Using repetitive measures generalized linear model, the interaction between the changes and the group was significant for all three tests. Benefits were also observed for participants’ stress level and perceived health in the intervention group compared to the control. Finally, no significant difference was observed between groups for metabolic health. Conclusions The current work suggests that a 12-week peer-led exercise program can improve physical function for adults age 50 and above.

AbstractObjectivesObjective of the study is to investigate whether Soft tissue mobilization (STM) can assist with static stretching to improve hamstring flexibly.MethodsThe design of the study was repeated measure design. The study was conducted at the physical therapy laboratory of Jamia Hamdard University, New Delhi. Participants included 78 healthy males with hamstring tightness, randomly assigned to either the control group (static stretching) or the experimental group (STM and static stretching). The experimental group received five sets of four different STM techniques, followed by two sets of 30-s static stretches 3 days per week over the course of 12 weeks. The control group received 5 min of sham ultrasound with an inactive probe prior to static stretching. Active knee extension test (AKE) was the outcome measure.ResultsBoth groups showed significant improvement in AKE compared with the baseline measurements. With ingroup analysis showed a significant difference in AKE across all measured time periods (weeks 4, 8, and 12) with pre-test in both groups (p<0.05). No significant difference in AKE improvement was found between groups (p>0.05).ConclusionThe results of this study show that STM prior to static stretching does not significantly improve hamstring flexibility among healthy individuals. Although this study cannot be generalized, the results may be useful for evidence-based practice in the management of hamstring tightness.

Abstract Background Although almost a year has passed since the Coronavirus disease 2019 (COVID-19) outbreak and promising reports of vaccines have been presented, we still have a long way until these measures are available for all. Furthermore, the most appropriate corticosteroid and dose in the treatment of COVID-19 have remained uncertain. We conducted a study to assess the effectiveness of methylprednisolone treatment versus dexamethasone for hospitalized COVID-19 patients. Methods In this prospective triple-blinded randomized controlled trial, we enrolled 86 hospitalized COVID-19 patients from August to November 2020, in Shiraz, Iran. The patients were randomly allocated into two groups to receive either methylprednisolone (2 mg/kg/day; intervention group) or dexamethasone (6 mg/kg/day; control group). Data were assessed based on a 9-point WHO ordinal scale extending from uninfected (point 0) to death (point 8). Results There were no significant differences between the groups on admission. However, the intervention group demonstrated significantly better clinical status compared to the control group at day 5 (4.02 vs. 5.21, p = 0.002) and day 10 (2.90 vs. 4.71, p = 0.001) of admission. There was also a significant difference in the overall mean score between the intervention group and the control group, (3.909 vs. 4.873 respectively, p = 0.004). The mean length of hospital stay was 7.43 ± 3.64 and 10.52 ± 5.47 days in the intervention and control groups, respectively (p = 0.015). The need for a ventilator was significantly lower in the intervention group than in the control group (18.2% vs 38.1% p = 0.040). Conclusion In hospitalized hypoxic COVID-19 patients, methylprednisolone demonstrated better results compared to dexamethasone. Trial registration The trial was registered with IRCT.IR (08/04/2020-No. IRCT20200204046369N1).
