RESUMO
BACKGROUND: Despite the presence of evidence that establishes a strong correlation between oxidative stress and thyroid cancer, there exists a scarcity of research that investigates the specific role of glutathione as an important antioxidant in this particular context. The objective of this study was to assess the altered balance of oxidative stress in cases of thyroid cancer, which includes both papillary thyroid carcinoma (PTC) and micro PTC (mPTC), by examining and comparing the total antioxidant capacity (TAC), total oxidant status (TOS), oxidative stress index (OSI), reduced glutathione (GSH), oxidized glutathione (GSSG), and GSSG/GSH ratio with those of individuals diagnosed with multinodular goiter (MNG) as well as Healthy subjects. MATERIALS AND METHODS: Plasma samples were collected from 92 patients (23 mPTC, 23 PTC, 23 MNG, 23 Healthy). The levels of TAC, TOS, GSH, and GSSG were measured using a commercial assay kits, and the OSI and GSSG/GSH ratio were calculated for each sample. Statistical analyses were performed to compare the oxidative stress between the groups. RESULTS: The plasma levels of TOS were significantly higher in the mPTC, PTC, and MNG groups compared to the Healthy individuals (p < 0.05). The OSI in the mPTC and PTC groups showed a significant increase compared to the Healthy group (p < 0.05). The levels of GSH in mPTC and PTC were markedly lower compared to the Healthy subjects (p < 0.01). Interestingly, the concentration of GSH in mPTC was found to be considerably lower than in PTC and MNG patients (p < 0.01). CONCLUSION: These findings indicate that GSH may be a useful biomarker for evaluating oxidative stress and antioxidant system status in patients with PTC, especially mPTC. Low levels of GSH may indicate increased levels of oxidative stress, which may contribute to the development and progression of mPTC to PTC.
RESUMO
AIM: This study aimed to explore food insecurity prevalence and experiences of adults with severe mental illness living in Northern England. METHODS: This mixed-methods cross-sectional study took place between March and October 2022. Participants were adults with self-reported severe mental illness living in Northern England. The survey included demographic, health, and financial questions. Food insecurity was measured using the US Department of Agriculture Adult Food Security measure. Quantitative data were analysed using descriptive statistics and binary logistic regression; and qualitative data using content analysis. RESULTS: In total, 135 participants completed the survey, with a mean age of 44.7 years (SD: 14.1, range: 18-75 years). Participants were predominantly male (53.3%), white (88%) and from Yorkshire (50.4%). The food insecurity prevalence was 50.4% (n = 68). There was statistical significance in food insecurity status by region (p = 0.001); impacts of severe mental illness on activities of daily living (p = 0.02); and the Covid pandemic on food access (p < 0.001). The North West had the highest prevalence of food insecurity (73.3%); followed by the Humber and North East regions (66.7%); and Yorkshire (33.8%). In multivariable binary logistic regression, severe mental illness' impact on daily living was the only predictive variable for food insecurity (odds ratio = 4.618, 95% confidence interval: 1.071-19.924, p = 0.04). CONCLUSION: The prevalence of food insecurity in this study is higher than is reported in similar studies (41%). Mental health practitioners should routinely assess and monitor food insecurity in people living with severe mental illness. Further research should focus on food insecurity interventions in this population.
RESUMO
The CRISPR system is a revolutionary genome editing tool that has the potential to revolutionize the field of cancer research and therapy. The ability to precisely target and edit specific genetic mutations that drive the growth and spread of tumors has opened up new possibilities for the development of more effective and personalized cancer treatments. In this review, we will discuss the different CRISPR-based strategies that have been proposed for cancer therapy, including inactivating genes that drive tumor growth, enhancing the immune response to cancer cells, repairing genetic mutations that cause cancer, and delivering cancer-killing molecules directly to tumor cells. We will also summarize the current state of preclinical studies and clinical trials of CRISPR-based cancer therapy, highlighting the most promising results and the challenges that still need to be overcome. Safety and delivery are also important challenges for CRISPR-based cancer therapy to become a viable clinical option. We will discuss the challenges and limitations that need to be overcome, such as off-target effects, safety, and delivery to the tumor site. Finally, we will provide an overview of the current challenges and opportunities in the field of CRISPR-based cancer therapy and discuss future directions for research and development. The CRISPR system has the potential to change the landscape of cancer research, and this review aims to provide an overview of the current state of the field and the challenges that need to be overcome to realize this potential.

Food insecurity means that a person does not have access to sufficient nutritious food for normal growth and health. Food insecurity can lead to many health problems such as obesity, heart disease, diabetes, and other long term health conditions. People living with a severe mental illness are more likely to experience food insecurity than people without mental illness. Peer-led in-depth interviews were conducted with adults with severe mental illness from Northern England, during which their experiences of food insecurity and strategies to tackle food insecurity were discussed. Interviews took place between March and December 2022, with interviews being transcribed and analysed using deductive and inductive thematic analysis. Thirteen interviews were conducted, finding that food insecurity in adults with severe mental illness was often a long-standing issue. Unemployment, the cost-of-living crisis and fuel poverty impacted on experiences of food insecurity. Difficulties accessing food banks such as transport, stigma, and the limited selection of available food was also discussed. Strategies to tackle food insecurity centred on making food banks more accessible and improving the quality of available food. Future research should aim to eradicate food insecurity for adults with severe mental illness, as limited research and action focuses on this population group over and above 'mental illness' or 'poor mental health'. Removing barriers to accessing food such as lack of transport, and providing food which is of adequate nutritional quality, should be prioritised, as well as tackling the stigma and accessibility issues surrounding food banks use.
RESUMO
BACKGROUND: People living with severe mental illness experience premature mortality from diet-related preventable illnesses. Yet, little research focuses on food insecurity with adults with severe mental illness. This coproduced study aimed to understand the experiences of adults with severe mental illness and food insecurity and strategies to help. METHODS: Following a pragmatism philosophical foundation, we undertook a mixed-methods study involving a survey (online and paper versions) and one-to-one semi-structured interviews (online and telephone) during March 7 to Dec 16, 2022. We recruited participants via existing severe mental illness service user groups and social media in Northern England. Eligible participants were adults (≥18 years) self-reporting a diagnosis of severe mental illness. Ethics approval was obtained from Teesside University and the Health Research Authority (Reference: 22/NR/0010; IRAS ID: 306281), with informed consent given. The target sample size, accounting for a typical survey response rate for people with severe mental illness of 10-20%, was 135. A target sample of 20 interviews was agreed to capture a range of views. Food insecurity was defined as the lack of financial resources needed to ensure someone has reliable access to enough food to meet their dietary, nutritional, and social needs. It is sometimes called food poverty. Quantitative data were analysed using descriptive statistics and binary logistic regression and qualitative data using thematic analysis. FINDINGS: 135 participants completed the survey (mean age 44·67 years [SD 14·1]). Participants were predominantly male (53%, n=72), white (87%, n=117), and from the Yorkshire region (50%, n=68). Overall, prevalence of food insecurity was 50·4% (n=68). Discussion across 13 interviews found food insecurity being a long-rooted experience, including familial and intergenerational experiences of food insecurity: "I grew up with this insecurity around food" (P002). Recommendations for tackling food insecurity centred on food banks, increasing accessibility, and reducing stigma: "I would like to get more information on where the centres are..." (P006) and "I was referred to, erm, a foodbank but it's still the stigma that's attached to it." (P002). INTERPRETATION: We found a higher prevalence of food insecurity in this study than in the general population (being 15%), yet limited research with adults with severe mental illness perpetuates food insecurity intergenerational injustices. Food insecurity should be eliminated. However, in the meanwhile, there should be widespread easy access to food banks offering nutritional foods. Limitations of this research include not reaching target sample size and a lack of ethnic diversity. FUNDING: National Institute of Health and Care Research (NIHR) Research for Patient Benefit.

Due to practical difficulties in quantifying fluoride exposure in populations, practical and accurate biomarkers can play a major role in the surveillance of fluoride. Among different fluoride biomarkers, spot urine and nail clippings have gained more attention due to their ease of acquisition. However, there is no robust consensus about the accuracy of these biomarkers for the estimation of fluoride exposure. This systematic review and meta-analysis aimed to synthesise evidence on the association between fluoride exposure and the fluoride concentration of spot urine and nail clippings. This review was conducted and reported using the PRISMA Statement. Nine databases (Medline, CINAHL, Web of Science, Scopus, ScienceDirect, Sage Journals Online, Campbell Collaboration, Cochrane Collaboration, and Embase); search engines (Google and Google Scholar); and grey literature were searched up to September 2022. All screening, data extraction, and quality assessments were conducted in duplicate. All experimental and observational research studies that reported the correlation between fluoride exposure and fluoride concentrations of spot urine and/or nail clippings were included. The Mixed-Methods Appraisal tool was used to assess the methodological quality of the included studies. A random effect meta-analysis was carried out to determine the relationship between fluoride exposure and fluoride concentration of biomarkers (i.e., spot urine and nail clippings). Forty-four studies met the inclusion criteria. A total of 694,578 participants were included in this review. Twenty-five studies were included in the meta-analysis. The primary meta-analysis showed a moderate correlation of 0.674 (95% confidence interval [CI]: 0.623-0.725, n = 25) between fluoride intake and fluoride concentration of spot urine and a strong correlation of 0.938 (95% CI: 0.520-1.355, n = 11) between fluoride intake and the fluoride concentration of nail clippings in all age groups. The findings of secondary meta-analyses showed a strong positive correlation between fluoride intake and fluoride/creatinine ratio of spot urine in children (0.929; 95% CI: 0.502-0.991; n = 2). In conclusion, spot urine and nail clippings have the potential to be employed as non-invasively obtained biomarkers in populations. However, due to the scarcity of high quality, relevant studies, more research is needed to establish the validity of these biomarkers.

BACKGROUND: Labor pain and fear of childbirth increase anxiety and stress in pregnant women. Therefore, the present study was conducted with the aim of determining the effect of Swedish massage with chamomile oil on pain and anxiety in a clinical trial. MATERIALS AND METHODS: The present study is a clinical trial on 159 women who were referred to 22 Bahman Hospital in Masjid Sulaiman City in 2021. The samples were randomly divided into three groups (Swedish massage with and without chamomile oil and control group). Pain intensity was assessed using the McGill Pain Scale and anxiety was assessed using the Vandenberg Anxiety Questionnaire. The data were analyzed with SPSS-20 software at a significance level of 0.05. Descriptive statistics (frequency, percentage, mean, and standard deviation) and inferential statistics (Chi-square, Fisher's exact, analysis of variance, and paired t) were used for data analysis. RESULTS: There were no significant statistical differences between the three groups in terms of obstetric and demographic information (P > 0.05). There was no significant relationship between the studied groups before the intervention in terms of labor pain intensity (P = 0.9) and anxiety (P-value = 0.426). After the intervention, the intensity of labor pain and mother's anxiety was significantly lower in the two intervention groups compared to the control group, and it was lower in the Swedish massage group with chamomile oil than the other two groups (P < 0.001). CONCLUSION: In the present study, Swedish massage with and without chamomile oil led to a decrease in pain intensity and anxiety. As a result, this method can be used as an effective method to reduce the intensity of pain and anxiety of pregnant mothers.
RESUMO
BACKGROUND: Mesenchymal stem cells (MSCs) are utilized as a carrier of anti-tumor agents in targeted anti-cancer therapy. Despite the improvements in this area, there are still some unsolved issues in determining the appropriate dose, method of administration and biodistribution of MSCs. The current study aimed to determine the influence of toll-like receptor 3 (TLR3) stimulation on the potential of MSCs migration to the neoplasm environment in the mouse melanoma model. METHODS AND RESULTS: Adipose-derived MSCs (ADMSCs) were isolated from the GFP+ transgenic C57BL/6 mouse and treated with different doses (1 µg/ml and 10 µg/ml) of polyinosinic-polycytidylic acid, the related TLR3 agonist, at various time points (1 and 4 h). Following the treatment, the expression of targeted genes such as α4, α5, and ß1 integrins and TGF-ß and IL-10 anti-inflammatory cytokines was determined using real-time PCR. In vivo live imaging evaluated the migration index of the intraperitoneally (IP) injected treated ADMSCs in a lung tumor-bearing mouse (C57BL/6) melanoma model (n = 5). The presented findings demonstrated that TLR3 stimulation enhanced both migration of ADMSCs to the tumor area compared with control group (n = 5) and expression of α4, α5, and ß1 integrins. It was also detected that the engagement of TLR3 resulted in the anti-inflammatory behavior of the cells, which might influence the directed movement of ADMSCs. CONCLUSION: This research identified that TLR3 activation might improve the migration via the stimulation of stress response in the cells and depending on the agonist concentration and time exposure, this activated pathway drives the migratory behavior of MSCs.

BACKGROUND: There is an increased interest in identifying practical and accurate biomarkers for fluoride exposure. Due to the narrow 'dose-gap' between the benefit of caries reduction and the risk of dental fluorosis, monitoring of fluoride exposure is vital when introducing any fluoridation programme for the prevention of dental caries. This scoping review aimed to ascertain the nature and extent of the available evidence on how spot urine and nail clippings are used to measure fluoride intake/exposure, by using a unique approach of mapping the studies according to population, setting, type of study design, methodology and analytical approach in community prevention programmes. METHODS: Multiple relevant databases were searched up to July 2021 for any study designs, including randomised controlled studies, quasi-experimental studies, surveys, retrospective and prospective cohort studies, case studies, phenomenological studies, and expert opinions. RESULTS: The search retrieved 9,222 studies of which 155 met the inclusion criteria. A high proportion of the studies (25.2%) originated from Latin America and the Caribbean continent subregion. However, per country, China recorded the highest number, followed by India and Mexico. The majority (62.6%) employed a cross-sectional study design, and 65.8% combined participants from different age groups. Of the included studies, 82.6% used spot urine samples as a biomarker for assessing fluoride intake/exposure. Water fluoride concentration was reported in 66.5% of the studies with 46.6% of all included studies reporting a water fluoride concentration of > 1.2 mg/L. The methods used in assessing oral hygiene and dietary intake were not reported in 72.3% and 71.0% of the included studies, respectively. Only 35.5% of the included studies assessed the relationship between fluoride exposure and excretion. CONCLUSIONS: This review revealed a large variability in the way in which spot urine samples and/or nail clippings are used to measure fluoride exposure in different settings and situations. Particularly, there are inconsistencies in the methodologies and the analytical approaches used in assessing fluoride exposure. Therefore, there is a need for more rigorous primary research studies using standardised approaches to determine the suitability of spot urine samples and nail clipping as biomarkers for monitoring fluoride exposure.

PURPOSE OF STUDY: Massage is widely used as a traditional technique during labor and delivery. The aim of this study was to evaluate the effect of Swedish massage with and without chamomile oil on delivery outcomes. METHODS: The present study was a randomized clinical trial on 154 primiparous pregnant women who were selected by random sampling method and divided into 3 groups: massage with chamomile oil (n = 53), massage without chamomile oil (n = 51), and control group (n = 50). Data collection tools included demographic and delivery information questionnaire, Visual Analogue Scale (VAS), maternal satisfaction with delivery scale, and Partograph form. In the two intervention groups, Swedish massage techniques (i.e., Effleurage, Petrissage, Vibration, and Superficial stroke) were performed with and without the use of chamomile oil since the active phase of labor (5 cm dilatation), while the control group received only routine labor care during labor. RESULTS: Swedish massage with chamomile oil significantly reduced the labor pain score, reduced the length of active phase and the second stage of labor, and increased the score of maternal satisfaction with the labor process (P < 0.001). In addition, there was a significant relationship between the type of study groups and the type of delivery (P < 0.043). CONCLUSION: The results of the study showed that using Swedish massage techniques with or without chamomile oil can improve labor outcomes. Swedish massage using chamomile oil was associated with better results compared to the same massage without using chamomile oil. Clinical trial code IRCT20200513047430N1.

Obesity remains a serious public health concern in rich countries and the current obesogenic food environments and food insecurity are predictors of this disease. The impact of these variables on rising obesity trends is, however, mixed and inconsistent, due to measurement issues and cross-sectional study designs. To further the work in this area, this review aimed to summarize quantitative and qualitative data on the relationship between these variables, among adults and children across high-income countries. A mixed-method systematic review was conducted using 13 electronic databases, up to August 2021. Two authors independently extracted data and evaluated quality of publications. Random-effects meta-analysis was used to estimate the odds ratio (OR) for the association between food insecurity and obesity. Where statistical pooling for extracted statistics related to food environments was not possible due to heterogeneity, a narrative synthesis was performed. Meta-analysis of 36,113 adults and children showed statistically significant associations between food insecurity and obesity (OR: 1.503, 95% confidence interval: 1.432-1.577, p < .05). Narrative synthesis showed association between different types of food environments and obesity. Findings from qualitative studies regarding a reliance on energy-dense, nutrient-poor foods owing to their affordability and accessibility aligned with findings from quantitative studies. Results from both qualitative and quantitative studies regarding the potential links between increased body weight and participation in food assistance programs such as food banks were supportive of weight gain. To address obesity among individuals experiencing food insecurity, wide-reaching approaches are required, especially among those surrounded by unhealthy food environments which could potentially influence food choice.
RESUMO
This novel and mixed-method study investigated food poverty conversations at the beginning of the COVID-19 pandemic and the subsequent national lockdown on the social media platform Twitter. NodeXL Pro software was used to collect tweets using the terms 'food' and 'poverty' in any order somewhere in a tweet sent on selected days between April 5 and May 23, 2020. The data obtained from NodeXL Pro were cleaned. Social network analysis tools were used to analyse and visualise our data. Using this method, sentiment-related words (positive or negative words), the top (the most mentioned) 10 hashtags, top words and top word pairs were identified. The patterns of word pairs communicated in our network were visualised based on each word pair's frequency. This also enabled us to carry out a content analysis to create coding of the word pairs' data. A total of 81 249 tweets were identified that contained the terms 'food' and 'poverty'. Our findings revealed that individuals' tweets overwhelmingly contained views about the increase in hunger, food poverty and food insecurity due to the COVID-19 pandemic. Twitter users perceived that when the pandemic measures began, many food-secure families were pushed into food insecurity due to a rapid rise in unemployment and rising poverty due to the quarantine and stay-at-home instructions in place at the time. They also addressed the sharp rise in food poverty being driven by panic buying, food shortages, food affordability and disruptions in food supply and food systems. Our analysis of this data suggests that to mitigate food poverty or to prevent a 'hunger pandemic' for future pandemic emergencies, comprehensive and longer term policy responses and economic supports are needed to strengthen the resilience of food systems. However, the highlighted limitations of this study must be considered.

BACKGROUND: The immunomodulatory properties of mesenchymal stem cells (MSCs) have made them a prospective treatment option for inflammatory and autoimmune disorders. Recent studies have found an association between the immunomodulatory function of MSCs and Toll-like receptors (TLRs). Here, we investigated the effect of priming with lipopolysaccharide (LPS) as TLR4 ligand or polyinosinic:polycytidylic acid (poly I:C) as TLR3 ligand on the immunomodulatory function of adipose-derived MSCs (ADMSCs) in vitro and for the first time in an adjuvant-induced arthritis model (AIA). METHODS: ADMSCs were treated with LPS or poly I:C for 1 h. Splenocyte proliferation in the presence of primed ADMSCs was assessed in vitro using an MTT assay. Next, we investigated the therapeutic effect of primed ADMSCs in vivo. Male Wistar rats were infused with complete Freund's adjuvant (CFA) to develop arthritis and then intraperitoneally treated with not-primed, poly I:C- or LPS-primed ADMSCs. Clinical signs, histopathological alteration, and serum and spleen cytokine levels were analyzed. RESULTS: Poly I:C-primed ADMSCs significantly reduced splenocytes proliferation, while ADMSCs primed with LPS increased splenocytes proliferation. Furthermore, poly I:C-primed ADMSCs significantly alleviated the clinical and histopathological severity and the secretion of inflammatory cytokines associated with Th17/Th1 such as IL-17 and IFN-γ. Poly I:C-primed ADMSCs also increased cytokines IL-10 and TGF-ß. TNF-α and IL-6 Levels were also markedly diminished in the serum of AIA animals treated with poly I:C-primed ADMSCs. In contrast, priming ADMSCs with LPS significantly reduced the therapeutic effect of ADMSCs in AIA animals. CONCLUSION: As a result of these findings, poly I:C priming may be a new technique for improving the therapeutic effects of MSCs in arthritic disorders.

The main objective of this study is to evaluate the quality of nurses' work lives and mental health during outbreaks. We also use the General Health Questionnaire-28 and Walton's QWL technique to assess the association between these two and their dimensions with demographic variables and each other. First, 165 nurses from COVID-19 medical centers in Iran filled surveys for this research. In an SPSS program, the data were examined. There was a strong link between mental health and age-related demographic factors. There was no evidence of a link between the quality of nurses' work life and their psychological health. However, there was a strong link between somatic symptoms and fair and appropriate compensation, as well as constitutionalism. The worst situations for work life quality were linked to the whole living area dimension. In contrast, the worst conditions for mental health were linked to the somatic symptoms dimension.

Cocirculation of multiple human papillomavirus (HPV) infections with low, probably high, and high-risk genotypes are to be associated with various grades of infections and cancer progression. The oncogenic high-risk HPVs are distributed and cocirculated throughout the world. This study was investigated to identify HPV genotypes related to genital disorders in unvaccinated women. The subjects were referred from clinics to a molecular lab for HPV testing in Iran as a low-coverage vaccinated country. HPVs DNAs of cervical scrapping and genital tissue specimens of 1,133 un-vaccinated women were genotyped using an in vitro diagnostic line probe (reverse hybridization) assay. In addition, phylogenetic trees were constructed on 100 MY09/MY11 polymerase chain reaction (PCR) amplicons of common genotypes of HPV L1 gene by Sanger sequencing. The mean age of the population study was 32.7 ± 8.0 and the mean age of HPV-positive cases was 31.6 ± 7.8. HPV DNA was detected in 57.8% (655/1133) of women subjects and 42.2% (478/1133) of cases were undetected. Among 655 HPV-positive cases, 639 subjects (56.4%) were related to defined genotypes and 16 subjects (1.4%) were untypeable. The highest prevalence rate of HPV genotypes was identified in the 25-34 years. The top 6 dominant HPVs in single and multiple genotypes were HPV6 (284/655 [43.4%]), HPV16 (111/655 [16.9%]), HPV31 (72/655 [11%]), HPV53 (67/655 [10.2%]), HPV11 (62/655 [9.5%]), and HPV52 (62/655 [9.5%]). Moreover, single, multiple and untypeable HPV genotypes were diagnosed as follows: 1 type (318/655 [48.5%]), 2 types (162/655 [24.8%]), 3 types (83/655 [12.7%]), 4 types (42/655 [6.5%]), more than 5 types (34/655 [5.3%]), and 1.4% un-typeable subjects. The sequenced partial L1 gene of HPV genotypes (GenBank databases under the accession numbers: MH253467-MH253566) confirmed and determined the cocirculated HPV genotypes' origins and addressed helpful insights into the future viral epidemiology investigations. Multiple HPV infections and cocirculation of various oncogenic HPV genotypes among the normal population (women and men) with asymptomatic forms are still challenging in unvaccinated communities. The preventive and organized surveillance programs for HPV screening are needed to be considered and compiled by health policy makers of low or unvaccinated countries.

BACKGROUND: Research indicates that food parcels provided by food banks are nutritionally poor. Food insecurity and the use of food banks are both rising, with detrimental effects on the dietary intake and health of users. This mixed-method systematic review aims to investigate the current nutritional adequacy of pre-packaged food parcels and whether using food banks reduces the food insecurity and improves the dietary intake of their users. METHODS: A mixed-method systematic literature review, restricted to articles published from 2015, was conducted using eight electronic databases, four grey literature databases and eight relevant websites. Quantitative findings, investigating the nutritional quality of food parcels and/or their impact on dietary intake or food insecurity, were presented narratively. Qualitative findings reporting the views of food bank users regarding food from food banks underwent thematic synthesis. These independent syntheses were integrated using configurative analysis and presented narratively. RESULTS: Of 2189 articles, 11 quantitative and 10 qualitative were included. Food parcels were inconsistent at meeting nutritional requirements and often failed to meet individual needs, including cultural and health preferences. Using food banks improved food security and dietary quality of users, allowing otherwise unachievable access to food. However, food insecurity remained, and is explained by limited food variety, quality and choice. The mixed-method findings support interventions to ensure consistent, adequate nutrition at food banks, including catering for individual needs. CONCLUSIONS: Food banks are a lifeline for those severely food insecure. However when used alone, food banks struggle to eliminate the heightened food insecurity of their users. Efforts to improve the nutritional quality of food parcels could improve the experiences and diet-related outcomes of those requiring food banks.

Background and Aims: Primiparous women experience high levels of anxiety before cesarean section. Therefore, this research aimed to investigate the effects of the Benson Relaxation Technique (BRT) and Music Therapy (MT) on the anxiety of primiparous women prior to cesarean section. Methods: A randomized controlled trial was carried out on 105 women scheduled for cesarean section. They were randomly assigned into three groups: BRT, MT, and control (n = 35 per group). The women in the BRT and MT groups performed exercises and listened to music, respectively, for 20 minutes prior to cesarean section. The State Anxiety Inventory was used to measure the women's anxiety in the groups before and after the intervention. Results: Within-group comparisons showed that the women in the BRT (t = 5.61, p < 0.001, effect size (Cohen's d) = 0.94) and MT (t = 3.83, p = 0.001, d = 0.64) groups had significantly lower anxiety after the interventions compared to before the interventions. Also, between-group comparisons revealed that anxiety after the intervention was significantly lower in the BRT and MT groups compared to the control group (p = 0.007). Conclusions: Although both of the BRT and MT helped with the reduction of anxiety among primiparous women before cesarean section, the BRT was shown more effective. These nonpharmacologic methods are safe and cost-effective and can improve well-being among women undergoing this invasive procedure. They can be used along with pharmacologic methods for reducing overreliance on medications.
RESUMO
AIMS/INTRODUCTION: To examine the incidence rate of severe non-proliferative and proliferative diabetic retinopathy (severe-NPDR/PDR) and determine its potential risk factors. MATERIALS AND METHODS: The study consisted of 1,169 participants (675 women) with type 2 diabetes mellitus, aged ≥20 years. A trained interviewer collected information about the history of pan-retinal photocoagulation as a result of diabetic retinopathy. Multivariable Cox proportional hazards regression models were applied. RESULTS: We found 187 cases (126 women) of severe-NPDR/PDR during a median follow-up period of 12.7 years; the corresponding incidence rate was 13.6 per 1,000 person-years. Being overweight (hazard ratio [HR], 95% confidence interval [CI] 0.60, 0.39-0.92) and obese (HR 0.48, 95% CI 0.27-0.83) were associated with lower risk, whereas being smoker (HR 1.75, 95% CI 1.12-2.74), having fasting plasma glucose levels 7.22-10.0 mmol/L (HR 2.81, 95% CI 1.70-4.62), fasting plasma glucose ≥10 mmol/L (HR 5.87, 95% CI 3.67-9.41), taking glucose-lowering medications (HR 2.58, 95% CI 1.87-3.56), prehypertension status (HR 1.65, 95% CI 1.05-2.58) and newly diagnosed hypertension (HR 1.96, 95% CI 1.06-3.65) increased the risk of severe-NPDR/PDR. Among newly diagnosed diabetes patients, being male was associated with a 59% lower risk of severe-NPDR/PDR (HR 0.41, 95% CI 0.21-0.79). Furthermore, patients who had an intermediate level of education (6-12 years) had a higher risk of developing PDR (HR 1.86, 95% CI 1.05-3.30) compared with those who had <6 years of education. CONCLUSIONS: Among Iranians with type 2 diabetes mellitus, 1.36% developed severe-NPDR/PDR annually. Normal bodyweight, being a smoker, out of target fasting plasma glucose level, prehypertension and newly diagnosed hypertension status were independent risk factors of severe-NPDR/PDR. Regarding the sight-threatening entity of advanced diabetic retinopathy, the multicomponent strategy to control diabetes, abstinence of smoking and tight control of blood pressure should be considered.

BACKGROUND: Considering the prevalence of mental health problems in older adults, this study aims to investigate the effect of inhalation aromatherapy using lavender and chamomile essential oils on depression, anxiety, and stress of community-dwelling older people. METHODS: A three-armed, parallel, randomized, and controlled trial design was used in this study. 183 participants were enrolled and randomly assigned to three groups (n = 61): the lavender, chamomile, and control groups. The participants in the experimental groups inhaled three drops of 1.5% lavender and chamomile essential oils for 30 nights. The participants in the control group inhaled only distilled water in a similar fashion. Data were collected using the Depression, Anxiety, and Stress-Scale (DASS) at baseline, immediately after the intervention, and one month after the intervention. Chi-square, Fisher's exact, one-way ANOVA, and repeated measures ANOVA were used for data analysis. RESULTS: Statistically significant improvement occurred in depression, anxiety, and stress levels immediately and one month after the intervention in lavender and chamomile groups compared to the control group (p < 0.01). CONCLUSION: Inhalation aromatherapy with both lavender and chamomile essential oils helped decrease depression, anxiety, and stress levels in community-dwelling older adults.
