Efficacy of curcumin for amelioration of radiotherapy-induced oral mucositis: a preliminary randomized controlled clinical trial.

BACKGROUND: Oral mucositis (OM) is one of the main problems in almost all patients undergoing head and neck radiotherapy (RT). Owning to the antioxidant and anti-inflammatory properties of curcumin, the effect of both oral and topical formulations of curcumin was assessed on radiation-induced OM (ROM) in this study. METHODS: The safety and efficacy of curcumin mouthwash 0.1% (w/v) and curcumin-nanocapsule were evaluated in ameliorating severity and pain/burning associated with OM during RT. The current randomized, placebo-controlled trial was conducted on 37 patients with head and neck cancers. Patients with grades 1 to 3 of ROM were randomized to receive one of the three interventions: curcumin mouthwash (0.1% w/v); Sinacurcumin soft gel containing 40 mg curcuminoids as nano-micelles (SinaCurcumin®40); or placebo mouthwash with a similar transparent appearance to curcumin mouthwash for 1 min three times daily during RT. Study evaluations were conducted at baseline and weekly thereafter for up to 3 weeks using the Numeric rating scale (NRS) and world health organization (WHO) scale. RESULTS: Among the 45 patients randomized, 37 (mean (SD) age of 53.36 (15.99) years; 14 [37.8%] women) completed the treatment according to the protocol. Patients treated with either oral or topical curcumin showed a significantly reduced severity and burning related to OM during the first 3 weeks after administration (P-Value < 0.001) as compared with the placebo. At study termination, more than 33% of subjects utilizing curcumin mouthwash and 15% of patients utilizing curcumin-nanocapsule remained ulcer free while all of the placebo-receiving subjects had OM. The reduction of NRS and WHO scale between curcumin groups was comparable without significant differences. CONCLUSION: Both curcumin mouthwash and nanocapsule were effective, safe, and well-tolerated in the treatment of radiation-induced OM. Higher doses of curcumin and larger sample sizes can be used for further investigation in future studies. TRIAL REGISTRATION: https://irct.ir/ IRCT20190810044500N17 (13/08/2021).

Effect of online solution-focused counseling on the sexual quality of life of women with a history of breast cancer: a clinical trial.

BACKGROUND: Breast cancer, as the most prevalent malignancy among women globally and in Iran, affects important aspects of the lives of the survivors of this condition, especially the quality of sexual life. Solution-focused brief therapy is one of the therapeutic counseling approaches used in various fields, including sexual function problems. In recent years, online and internet-mediated counseling methods have received more attention. OBJECTIVE: This study investigated the effect of online counseling based on a solution-focused approach in improving the sexual quality of life (SQL) of women with breast cancer. MATERIALS & METHODS: In this clinical trial, the research population consisted of women with a history of breast cancer with a recorded file in Shahid Ramazanzadeh Radiation Oncology Center in Yazd and at least 6 months had elapsed since the end of their treatment. After selecting 80 samples based on the random numbers table, they were assigned into two groups of 40, i.e., active control and intervention, using random allocation software. Participants in the intervention group were given online counseling through the Skyroom space with a solution-focused approach. Eight weekly sessions were held each lasting 60-90 min. The active control group received an educational file to improve the SQL. All participants in two groups completed the SQL questionnaire at the beginning of the study, at the end of the study, and 1 month after the study. Data were analyzed with SPSS18 using descriptive and inferential statistics. RESULTS: Finally, the data of 33 participants in the intervention group and 32 participants in the active control group were analyzed. The mean score of the SQL in the intervention group increased from 68.57 ± 18.63 before the intervention to 78.84 ± 12.7 immediately after the intervention (P = 0.015), and to 79.60 ± 19.88 1 month after the intervention (P = 0.012). The mean score of the SQL in the active control group increased from 64.45 ± 22.76 before the intervention to 67.20 ± 20.29 immediately after the intervention (P = 0.33), and to 68.70 ± 20.76 1 month after the intervention (P = 0.62). The difference in the mean score of the SQL before and after the intervention between the two groups was statistically significant (P = 0.007). CONCLUSION: It seems that the use of counseling with a solution-focused approach in women with a history of breast cancer improves the SQL. Thus, considering the effectiveness of this type of training, it is recommended that this method be used as a sexual health counseling method in medical centers. TRIAL REGISTRATION: This clinical trial is registered in Iranian registry center of clinical trials (IRCT) by registration code of IRCT20201221049784N1 in 06/03/2021.

Effects of topical timolol for the prevention of radiation-induced dermatitis in breast cancer: a pilot triple-blind, placebo-controlled trial.

INTRODUCTION: Radiation therapy is one of the standard methods in the treatment of breast cancer. Radiotherapy-induced dermatitis (RID) is a common complication of radiotherapy (RT) resulting in less tolerance in RT and even discontinuation of treatment. Timolol is a ß-adrenergic receptor antagonist that presents the best wound healing effects on both chronic and incurable wound healing. Topical forms of timolol could be effective in the prevention of RID due to the role of ß-adrenergic receptors in skin cells and keratinocyte migration, as well as the anti-inflammatory effect of timolol. However, no placebo-controlled randomized trial is available to confirm its role. The current trial aimed to evaluate the efficacy of topical timolol 0.5% (w/w) on the RID severity and patients' quality of life (QOL). METHOD: Patients aged older than 18 years with positive histology confirmed the diagnosis of invasive and localized breast cancer were included. Patients were randomized based on the random number table to receive each of the interventions of timolol 0.5% (w/w) or placebo topical gels from the first day of initiation of RT and for 6 weeks, a thin layer of gel twice daily. Patients were asked to use a thin layer of gel for at least two hours before and after radiation therapy. Primary outcomes were acute radiation dermatitis (ARD) grade using Radiation Therapy Oncology Group and the European Organization for Research and Treatment of Cancer (RTOG/EORTC) scale and severity of desquamation based on Common Terminology Criteria for Adverse Events (CTCAE), version 5.0. Secondary outcomes were QOL based on Skindex16 (SD-16), maximum grade of ARD, and time of initial RD occurrence. RESULTS: A total of 64 female patients with an age range of 33 to 79 years were included. The means (SD) of age were 53.88 (11.02) and 54.88 (12.48) in the control and timolol groups, respectively. Considering the RTOG/EORTC and CTCAE scores the difference between groups was insignificant (P-Value = 0.182 and P-Value = 0.182, respectively). In addition, the mean (SD) of time of initial RID occurrence in placebo and timolol groups were 4.09 (0.588) and 4.53 (0.983) weeks, respectively (P-Value = 0.035). The maximum grade of RID over time was significantly lower in the timolol group. During the study period, 75.0% of patients in placebo groups had grade 2 of ARD while in the timolol group it was 31.3% (P-Value = 0.002). QoL was not significantly different between groups (P-Value = 0.148). CONCLUSION: Although the topical formulation of timolol, 0.5% (w/w), was found to reduce the average maximum grade of ARD and increase the mean (SD) time of initial RID occurrence, it showed no effect on ARD, severity, and QOL. However, future clinical trials should be performed to assess timolol gel formulation in larger study populations. TRIAL REGISTRATION: https://irct.ir/ IRCT20190810044500N11 (17/03/2021).

European trends in radiology: investigating factors affecting the number of examinations and the effective dose.

The advances in technology have led to a growing trend in population exposure to radiation emerging from the invention of high-dose procedures. It is, for example, estimated that annually 1.2% of cancers are induced by radiological scans in Norway. This study aims to investigate and discuss the frequency and dose trends of radiological examinations in Europe. European Commission (EC) launched projects to gain information for medical exposures in 2004 and 2011. In this study, the European Commission Radiation Protection (RP) reports No. 154 and 180 have been reviewed. The RP 154 countries' data were extracted from both reports, and the average variation trend of the number of examinations and effective doses were studied. According to the results, plain radiography and fluoroscopy witnessed a reduction in the frequency and effective dose per examination. Nevertheless, European collective dose encountered an average increase of 23%, which resulted from a growing tendency for implementation of high-dose procedures such as CT scans and interventional examinations. It is worth noting that most of the CT procedures have undergone an increase in effective dose per examination. Although demand and dose per examination in some radiological procedures (such as intravenous urography (IVU) have been reduced, population collective dose is still rising due to the increasing demand for CT scan procedures. Even though the individual risks are not considerable, it can, in a large scale, threaten the health of the people at the present time. Due to this fact, better justification should be addressed so as to reduce population exposure.

Psychometric properties of the COVID-19 safety measures questionnaire in the employees of the radiation therapy center.

BACKGROUND: Due to the effect of coronavirus disease 2019 (COVID-19) outbreak on the continuation, schedule, and efficiency of radiation therapy, this study aimed to investigate the reliability and validity of the COVID-19 Safety Measures (CSM) questionnaire at the radiation therapy center. MATERIALS AND METHODS: In this analytical cross-sectional study, which all personnel of the radiation therapy center (20 people) participated, the validity and reliability of the 16-item CSM questionnaire were investigated. Cultural adaptation, face validity, content validity, test-retest reliability, and internal consistency were evaluated. For face and content validity, impact score, content validity ratio, and content validity index (CVR and CVI) were calculated, respectively. Also, internal consistency and stability reliability were calculated with Kuder-Richardson (KR20) alpha and Pearson correlation coefficient and intraclass correlation (ICC), respectively. Data analysis was performed using Statistical Package for the Social Sciences (SPSS) 24 with a significant level of 5%. RESULTS: Out of 20 employees, 70% (14 people) were female, 75% (15 people) were married and the mean age (SD) was 32.4 (6.35) years. Scale-based Kuder-Richardson alpha, S-CVI, ICC, and confidence interval were 0.79, 0.97, 0.68, and 0.38-0.89, respectively. CONCLUSION: The validity and reliability of the 16-item CSM questionnaire were confirmed. Therefore, the application of this scale is recommended.

Effectiveness of motion graphic-based narrative therapy with a cognitive-behavioral approach in reducing fluoride varnish therapy anxiety for six-year-old children.

BACKGROUND: Fluoride varnish therapy (FVT) is a dental caries preventive service that its effectiveness has been well documented. A lot of children, especially the five-year-old and six-year-old ones, are suffering with anxiety during this service and do not readily allow it. The present study aimed to cast light on the effect of motion graphic-based narrative story with a cognitive-behavioral approach in reducing FVT anxiety among six-year-old children. MATERIALS AND METHODS: This study was an intervention trial type that was conducted in Ardabil city and among school students. Five children suffering from FVT anxiety were randomly selected for the intervention. First, Venham and Gaulin-Kremer's anxiety scale was completed for them. The motion graphic-based narrative therapy was implemented for six weeks. Session 1 was assigned to filling the questionnaire and collecting data. The motion graphic-based narrative therapy started from the second session. The anxiety scale was filled for the children every ten days for a total of four times. The results were analyzed by Blanchard and Schwarz's progress formula and control charts. The intervention sessions included gathering information, watching motion graphics, relaxation skills, watching the process of performing fluoride varnish therapy, teaching the advantages of fluoride varnish therapy, and in the last session performing fluoride varnish therapy with the technique of attention diversion while watching motion graphics. RESULTS: The motion graphic-based narrative therapy by the cognitive-behavioral approach proved effective in reducing anxiety. At the end of the intervention sessions, the level of anxiety decreased from 8 to 2.2 and the statistical control chart of the process shows that the intervention process is stable and the stability in order to reduce anxiety and the results are within the control limits. CONCLUSION: The results show that motion graphic-based narrative therapy can be a psychotherapy method for reducing the symptoms of dental anxiety among children.

Effectiveness of telephone-based screening and triage during COVID-19 outbreak in the promoted primary healthcare system: a case study in Ardabil province, Iran.

Aims: Screening services for early detection of patients is one of the important capabilities of the health system with a proper referral system. In the crisis of respiratory infection of Covid-19, screening based on symptoms is one of the key measures. The aim of the current study was to evaluate the telephone-based screening and triage services in the promoted primary healthcare system with regard to the Covid-19 outbreak, in terms of reducing unnecessary referrals to the hospital. Methods: This is a descriptive cross-sectional study conducted in two stages on 1,406,635 households during March/April 2020 in Ardabil province for screening and early detection of Covid-19 disease. In the first stage, conducted by trained healthcare providers through telephone, individuals suspected of Covid-19 were identified. In the second stage, the individuals were referred to the second level of service in comprehensive healthcare centers (16- or 24-h centers) for clinical evaluation by a physician. Results: The results showed that before establishing a screening and triage system for patients in comprehensive healthcare centers, all patients were referred directly to the hospital, while after the implementation of the program, a significant reduction in hospital visits was observed and a large number of patients undertook the care and triage services in comprehensive healthcare centers. Conclusion: The use of a grading system in referring patients with suspected cases, triage of patients according to symptoms at the comprehensive health centers, and activation of home isolation were the most important factors in reducing the burden of unnecessary referrals of patients to the hospital.

Multifunctional PEGylated Niosomal Nanoparticle-Loaded Herbal Drugs as a Novel Nano-Radiosensitizer and Stimuli-Sensitive Nanocarrier for Synergistic Cancer Therapy.

Nowadays, radiotherapy is one of the most effective treatments for breast cancer. In order to overcome the radioresistance of cancer cells, radio-sensitizing agents can be used combined with irradiation to increase the therapeutic efficiency. Curcumin can enhance the radiosensitivity of cancer cells and decrease their viability by the accumulation of these cells in the G2 phase. The encapsulation of curcumin in a nanoniosomal delivery system increases aqueous solubility and bioavailability, resulting in increased radio sensitivity. The present study aimed to enhance the radio-sensitizing effect of the curcumin-containing nanoniosome (Cur-Nio) when combined with irradiation. Thus, curcumin (0.5 mg ml-1) was loaded on a PEGylated nanoniosome containing Tween 60, cholesterol, DOTAP, and 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-poly(ethylene glycol) (DSPE-PEG) (at ratios of 70:30:10:5, respectively) by the thin-film hydration method. The particle size, zeta potential, entrapment efficiency, and drug-release rate of formulated nanoniosomes were determined. In order to assess cytotoxicity and apoptosis, different doses of irradiation along with various concentrations of free curcumin and Cur-Nio (single or in combination with irradiation) were treated with breast cancer cells. The particle size and zeta potential of Cur-Nio were reported to be 117.5 nm and -15.1 mV, respectively. The entrapment efficiency (EE%) and loading capacities were 72.3% and 6.68%, respectively. The drug-release rate during 6 h was 65.9%. Cell survival in the presence of curcumin at doses of 1 and 3 Gy showed a significant reduction compared with cells irradiated at 48 h and 72 h (p < 0.000). Also, the rate of cytotoxicity and apoptosis was significantly higher in cells treated with the combination of curcumin-containing nanoniosomes and irradiation in comparison with those treated with free curcumin. These findings indicate that the efficacy of pre-treatment with Cur-Nio as a radiosensitizer during radiotherapy enhances irradiation-induced breast cancer cell apoptosis and is a useful strategy to increase the effectiveness of breast cancer therapy.

The effectiveness of home-use photobiomodulation toothbrush for treating dentin hypersensitivity: A pilot study.

BACKGROUND AND AIMS: Dentin hypersensitivity is a frequent oral condition among patients suffering from gingival recession. Recent studies have suggested that photobiomodulation has the potential to reduce inflammation and relieve pain. The present study aims to assess the effectiveness of a new design of photobiomodulation toothbrush with specific irradiation parameters as a homecare device in treating dentin hypersensitivity and to compare its therapeutic effect with that of fluoride varnish. MATERIALS AND METHODS: Thirty patients with gingival recession and dentin hypersensitivity were selected and randomly assigned to three groups of equal size: fluoride varnish, photobiomodulation, and the combination. Dentin pain and hypersensitivity were measured using visual analog scale (VAS) by two distinct tests: the contact test with a periodontal probe and the air blast test on the areas of gingival recession and denuded root; once at baseline and again one month after the initial application of treatments. Laser irradiation was carried out at the wavelength of 660 nm in CW with an output power of 40 mW for 30 seconds per spot (1.2 J per spot, 6 J/cm2 energy density, and 200 mW/cm2 power density), perpendicularly to denuded root surfaces in non-contact mode. RESULTS: A significant reduction in dentin pain and hypersensitivity was observed in all three groups. However, the reduction was significantly greater in the combination group. CONCLUSION: At-home treatment of dentin hypersensitivity with photobiomodulation toothbrush is a convenient, safe, and effective method for the management of dentin hypersensitivity.

Malignant myopericytoma is exceedingly rare. A 15-year old girl presented with slowly progressive mass over left shoulder region. Histopathology and immunohistochemistry after complete excision revealed it as malignant myopericytoma.

Radiation-induced hypopituitarism in children with acute lymphoblastic leukemia.

BACKGROUND: Acute Lymphoblastic Leukemia (ALL) is the most common malignancy among children for whom radiotherapy and chemotherapy are used for treatment. When hypothalamus-pituitary axis is exposed to radiotherapy, children's hormone level and quality of life are influenced. The aim of this study is to determine late effects of radiotherapy on hormonal level in these patients. MATERIALS AND METHODS: In this study 27 children with ALL, who have been referred to Shahid Ramezanzadeh Radiation Oncology Center in Yazd-Iran and received 18-24 Gy whole brain radiation with Cobalt 60 or 9 MV linear accelerator, were assessed. These patient's basic weight, height and hormonal levels were measured before radiotherapy and also after different periods of time. RESULTS: GHD (growth hormone deficiency) after clonidine stimulation test was observed in 44% (n=12) and that in 50% of them (n=6), less than 1 year, had been passed from their radiation therapy. None of these patients demonstrated hormone deficiency in other axes. CONCLUSIONS: This study showed that even application of a 18-24 Gy radiation dose might influence growth hormone levels; therefore, we recommend reduction of radiotherapy dose in such patients whenever possible.
