RESUMO

Cholangiocarcinoma (CCA), caused mainly by Opisthorchis viverrini (OV) infection, is a public health issue. Health literacy can play a significant role in preventing OV and CCA and adopting preventive behaviors. Therefore, this study aimed to evaluate, summarize, and synthesize the current evidence on health literacy programs for preventing OV and CCA.A systematic literature search, with Thai and English languages, was performed using electronic databases through PubMed, Google Scholar, ThaiJo, ThaiLis, and Embase to identify studies examining health literacy programs to prevent OV and CCA. We followed PRISMA 2020 guidelines. In addition, we used the RevMan software to perform a meta-analysis to analyze effect sizes using a fixed-effects model and measures of heterogeneity using Cochran's Q and I2. This meta-analysis included seven studies that met the criteria. The results showed that the people who received a program had an increased health literacy overall and in each aspect with a statistically significant (p < 0.001). So, health literacy programs can assist people in understanding their health and gaining access to health information and services. Additionally, the effect of programs (communication abilities, self-management, media and information literacy, and decision-making in practice) can help prevent OV and CCA. As a result, multi-disciplinary healthcare teams are crucial to developing preventive programs to prevent OV and CCA. Further studies need to be done and applied to these programs to modify behavior to avoid other diseases.

RESUMO

We are experiencing a revolution in regenerative medicine. Recent developments in organoid technology have provided unique opportunities for studying human biology and diseases. Indeed, organoid models have revolutionized the in vitro culture tools for biomedical research by creating robust three-dimensional (3D) architecture to recapitulate the primary tissues' cellular heterogeneity, structure, and functions. Such organoid technology enables researchers to re-create human organs and diseases model in a culture dish. It thus holds excellent promises for many translational applications such as regenerative medicine, drug discovery, and precision medicine. This review summarizes the current knowledge on the progression and promotion of organoid models, particularly with the heart disease approach. We discuss the usefulness of clinical applications of cardiac organoids and ultimately highlight the currently advanced therapeutic strategies in vitro model of organoids aimed at personalizing heart disease treatment.

RESUMO

The serious problems of conventional breast cancer therapy strategies such as drug resistance, severe side effects, and lack of selectivity prompted the development of various cold atmospheric plasma (CAP) devices. Due to its advanced technology, CAP can produce a unique environment rich in reactive oxygen and nitrogen species (RONS), photons, charged ions, and an electric field, making it a promising revolutionary platform for cancer therapy. Despite substantial technological successes, CAP-based therapeutic systems are encounter with distinct limitations, including low control of the generated RONS, poor knowledge about its anticancer mechanisms, and challenges concerning designing, manufacturing, clinical translation, and commercialization, which must be resolved. The latest developments in CAP-based therapeutic systems for breast cancer treatment are discussed in this review. More significantly, the integration of CAP-based medicine approaches with other breast cancer therapies, including chemo- and nanotherapy is thoroughly addressed.

RESUMO

PURPOSE: This study investigated the effect of oral melatonin as a premedication before cataract surgery on pain score, anxiety, surgical conditions, and intraocular pressure (IOP) during cataract surgery with phacoemulsification under topical anesthesia. DESIGN: This randomized, double-blind prospective study was conducted among 120 patients aged 50 to 80. METHODS: Patients were randomly assigned to receive either sublingual melatonin 3 mg or placebo 60 min before surgery. Verbal anxiety and pain scores, heart rate, systolic and diastolic blood pressure, intraocular pressure, and quality of surgical conditions were recorded. The results were analyzed using SPSS 23 software, and statistical analysis consisted of χ2 test and t-test, and a P value less than .05 was considered significant. FINDINGS: There was a significant difference between the two groups regarding pain after the surgery before being discharged from the recovery room. The mean pain score in the melatonin group was lower than the placebo group in T4 (in the postoperative ward) (P < .05). The anxiety score of patients was lower in the melatonin group in T3 and T4 (during surgery and in the postoperative ward, respectively) (P < .05). IOP was significantly lower in the case group at the end of the surgery after receiving premedication (P = .021). CONCLUSIONS: This study showed that 3 mg Sublingual melatonin premedication for patients undergoing cataract surgery under topical anesthesia reduced patients' anxiety scores, pain score, and IOP.

RESUMO

Although studies have extensively discussed the effects of COVID-19 on global health behaviors, little is known about the extent of COVID-19 preventive behaviors and their negative effects on the working-age population of Bangkok, Thailand. Therefore, this study aimed to examine health-risk behaviors, COVID-19 preventive behaviors, and the impact of the COVID-19 pandemic among the Thai working-age population. An online cross-sectional survey was conducted among working-age adults through a self-administered questionnaire. Data were analyzed with descriptive statistics and stepwise multiple regression. Of the 313 Thai participants (227 females, 72.5%), 84.0% had high levels of health-risk behaviors for preventing COVID-19 infection, most respondents (89.1%) had high levels of knowledge about COVID-19, and most respondents (61.7%) had high levels of overall COVID-19 preventive behaviors. Stepwise multiple regression revealed that health-risk behaviors (ß = 0.445), knowledge of COVID-19 (ß = 0.148), gender (ß = 0.145), and age (ß = 0.133) were predictive of COVID-19 preventive behaviors. Additionally, most respondents (48.9%) had moderate overall effects from COVID-19. Based on our findings, these factors must be considered when implementing public policies to improve COVID-19 preventive behaviors among the currently employed working-age population. In addition, appropriate interventions must be established and evaluated for the pandemic's long-term effects.

RESUMO

Background: The societal challenges presented by fear related to the coronavirus disease (COVID-19) pandemic may present unique challenges for an individual's mental health. However, the moderating role of compassion in the relationship between fear of COVID-19 and mental health has not been well-studied. The present study aimed to explore the association between fear of COVID-19 and mental health, as well as test the buffering role of compassion in this relationship. Methods: The participants in this study were 325 Iranian undergraduate students (228 females), aged 18-25 years, who completed questionnaires posted on social networks via a web-based platform. Results: The results showed that fear of COVID-19 was positively related with physical symptoms, social function, depressive symptoms, and anxiety symptoms. The results also showed that compassion was negatively associated with physical symptoms, social function, depressive symptoms, and anxiety symptoms. The interaction-moderation analysis revealed that compassion moderated the relationship between fear of COVID-19 and subscale of mental health. Conclusion: Results highlight the important role of compassion in diminishing the effect of fear of COVID-19 on the mental health (physical symptoms, social function, depressive symptoms, and anxiety symptoms) of undergraduate students.

RESUMO

BACKGROUND: Dancing is a type of physical activity that has been associated with physical benefits in older adults. Regular dancing can help maintain physical function and improve the quality of life in this population. This review evaluated randomized control trials (RCTs) of the effectiveness of dance programs on the physical function of healthy older adults. METHODS: We systematically searched four databases (PubMed, Google Scholar, Embase, and ThaiLis) through December 2021 for primary studies evaluating dance programs in healthy older adults aged 60 years and over. The meta-analysis used a random-effects model to compute the effect sizes using a forest plot and Cochran's Q and I2 statistics as heterogeneity measures. RESULTS: Eight types of dance programs showed significantly improved physical function. Muscle strength was assessed using the five times sit-to-stand test (I2=89%; p=0.003), chair-sit-to-stand-30S test (I2=75%; p=0.006), and 30-s arm curl test (I2=22%; p=0.260). Static balance was evaluated using the Berg-balance scales test (I2=0%; p=0.620) and the one-leg-stand test (I2=32%; p=0.220). Dynamic balance was tested based on the time up-and-go and eight-foot up-and-go tests (I2=51%; p=0.110). Flexibility was assessed based on the back-scratch (I2=56%; p=0.130) and sit-and-reach test (I2=0%; p=0.930). CONCLUSION: Dance exercise programs improved muscle strength, balance, and flexibility. Such programs are effective and safe for healthy older adults for use as daily exercise to promote health. Therefore, researchers, healthcare providers, and policymakers should establish properly organized dance interventions to improve physical function in healthy older adults.

RESUMO

INTRODUCTION/OBJECTIVE: This review aimed to summarize articles describing caregiver burden and the relationship between health outcomes as well as describing interventions focusing on this population. METHODS: The review used the PRISMA statement and Whittemore and Knafl guidelines. The search engines Scopus, PubMed, Ovid (PsycINFO), and CINAHL were searched for articles published in English. RESULTS: This review included 30 studies that met the criteria. Physical, psychological, and social factors were associated with HF caregiver burden. HF caregiver interventions included health education, post-discharge home visits, phone calls, counseling, and support groups that demonstrated some potential to reduce the caregivers' burden. DISCUSSION: Healthcare provider team should screen for caregiver burden and promote healthy behaviors, and strategies to improve quality of life. Further studies should include caregivers as care team members and embed social networking in the interventions for reducing HF caregiver burden. The caregivers' burden could influence the poor outcomes of care, including physical, psychological, societal, and functional dimensions. Future interventions should develop to alleviate HF caregiver burden.

RESUMO

A new approach has been developed for environmentally friendly C-C cross-coupling reactions using bi-functional Pd(ii)-salen complex-embedded cellulose filter paper (FP@Si-PdII-Salen-[IM]OH). A Pd(ii)-salen complex bearing imidazolium [OH]-moieties was covalently embedded into a plain filter paper, then used as an efficient portable catalyst for the Heck, Suzuki, and Sonogashira cross-coupling reactions under environmentally friendly conditions via the filtration method. The catalytic filter paper properties were studied by EDX, XPS, TGA, ATR, XRD, and FESEM analyses. The reactions were catalyzed during reactants' filtration over the catalytic filter paper. The modified filter paper was set up over a funnel and the reactants were passed through the catalytic filter paper several times. The effect of reaction parameters including loading of Pd(ii)-salen complex, temperature, solvent, and contact time were carefully studied and also the optimal model of conditions was presented by the design expert software. High to excellent yields were obtained for all C-C coupling types with 5 to 8 filtration times. Under optimal conditions, all coupling reactions showed high selectivity and efficiency. Another advantage of the modified filter paper was its stability and reusability for several times with preservation of catalytic activity and swellability.

RESUMO

The coronavirus disease 2019 (COVID-19) pandemic has affected the health behaviors of older adults. Thus, the factors predicting the COVID-19 preventive behaviors of older adults during the COVID-19 outbreak should be examined. Therefore, this study aimed to assess the COVID-19 preventive behaviors of older adults and explore the factors predicting these. A cross-sectional study was performed with 400 older adults who were selected using the cluster sampling technique. The associations of all variables in preventing COVID-19 infection with COVID-19 preventive behaviors were examined using stepwise multiple regression. The study results revealed that 70.8% of the study participants had high levels of COVID-19 preventive behaviors. Among these, self-efficacy in preventing COVID-19 infection (ß = 0.224) showed the highest ability to predict COVID-19 preventive behaviors, followed by COVID-19 response efficacy (ß = 0.171), knowledge about COVID-19 (ß = 0.110), and gender (ß = -0.102). Older adults adopted protective behaviors at the beginning of the COVID-19 pandemic. The predictors of these behaviors should be considered while designing and developing appropriate COVID-19 preventive behavior interventions, aimed at inducing behavioral modifications to reduce further infection with and spread of COVID-19.

RESUMO

INTRODUCTION/OBJECTIVE: To examine the effects of applying social marketing and Health Belief Model (HBM) in preventing cholangiocarcinoma (CCA) in high-risk areas of Thailand. METHODS: About 2 randomized high-risk areas of CCA from multiple-stage sampling were assigned as study areas. The 150 participants were allocated to the experimental group, which received a 12-week health education program that applied social marketing and HBM. The comparison group received the usual services. Data were collected by a questionnaire created by the researchers. We employed descriptive, inferential statistics (paired t-test and independent t-test) for normal distribution, while Analysis of Covariance (ANCOVA) was used for mean scores differing before the experiment. RESULTS: After the experiment, the mean scores of the perceived risk of CCA, perceived severity of CCA, perceived benefits of CCA prevention, perceived barriers to CCA prevention, and correct behaviors of CCA prevention in the experimental group were significantly higher than those before the experiment the .05 level. They were also considerably higher than those of the comparison group at the .05 level. CONCLUSION: This is the first study to integrate social marketing and HBM for CCA prevention. Therefore, formulating policies or measures to prevent disease through public communication will form a model to avoid CCA and create a channel for distributing useful information to the general public.

RESUMO

This systematic review and meta-analysis aimed to estimate the pooled prevalence of (intimate partner violence) IPV against pregnant women in the COVID-19 pandemic. A literature search was conducted in PubMed, Web of Science, and Scopus for observational studies regarding the prevalence of IPV against pregnant women during the COVID-19 pandemic. The search was performed with the following keywords: intimate partner violence, domestic violence, battered women, wife assault, partner assault, wife abuse, partner abuse, femicide, domestic homicide, pregnancy, gestation, pregnant women, COVID-19, SARS-CoV-2, 2019-nCoV, Coronavirus Disease-19, 2019 Novel Coronavirus, Wuhan Coronavirus, SARS Coronavirus 2, Wuhan Seafood Market Pneumonia Virus. Heterogeneity between the studies was assessed using Cochran's Q test and I2 index. In addition, a random-effects model was used to estimate the prevalence of IPV. Data analysis was performed in Stata software version 16. Six articles met our inclusion criteria, which were conducted on 2213 pregnant women. The pooled prevalence of total IPV was estimated at 22 percent (95 percent Confidence Interval [CI]: 4-40 percent). Moreover, the pooled prevalence of psychological, physical, and sexual violence was reported to be 24 percent (95 percent CI: 13-35 percent), 14 percent (95 percent CI: 7-20 percent), and 6 percent (95 percent CI: 4-9 percent), respectively. Publication bias was significant (P = .01). According to the results, IPV against pregnant women has been relatively prevalent during the COVID-19 pandemic. Therefore, identifying the women who are at the risk of IPV is essential to preventing the consequences of maternal-fetal abuse and designing strategies to facilitate the reporting of violence during pandemics.

RESUMO

Reflective functioning is the process of reflecting on the thoughts and feelings of oneself and others and is foundational to healthy human relationships. The 54-item Reflective Function Questionnaire (RFQ) is a self-report measure that assesses reflective functioning, initially developed while studying individuals with borderline personality disorder (BPD) . The purpose of the present study was to translate the RFQ from English to Persian and evaluate its reliability and validity among Iranian prisoners. The sample of this study included 509 (455 men and 54 women) Iranian prisoners. Findings confirm the translated measure had acceptable face and content validity. A confirmatory factor analysis (CFA) confirmed two dimensions of certainty (RFQ-c) and uncertainty (RFQ-u) of reflective functioning. The correlation analysis showed positive relationships between the dimensions of the RFQ and the borderline personality symptoms questionnaire and the emotional dissatisfaction questionnaire. Correlation analysis also showed negative associations between the dimensions of the RFQ and the Toronto Basic Empathy Scale (BES) and the Kentucky Inventory of Mindfulness Skills (KIMS) questionnaire, confirming the concurrent validity of the RFQ. The Cronbach's alphas of the RFQ-c and RFQ-u subscales were .69 and .7 respectively, which demonstrated relatively acceptable internal consistency. The results of the analysis demonstrated that the translated RFQ had desirable psychometric properties for evaluating reflective function among Iranian prisoners.

RESUMO

Despite substantial developments in conventional treatments such as surgery, chemotherapy, radiotherapy, endocrine therapy, and molecular-targeted therapy, breast cancer remains the leading cause of cancer mortality in women. Currently, chimeric antigen receptor (CAR)-redirected immune cell therapy has emerged as an innovative immunotherapeutic approach to ameliorate survival rates of breast cancer patients by eliciting cytotoxic activity against cognate tumour-associated antigens expressing tumour cells. As a crucial component of adaptive immunity, T cells and NK cells, as the central innate immune cells, are two types of pivotal candidates for CAR engineering in treating solid malignancies. However, the biological distinctions between NK cells- and T cells lead to differences in cancer immunotherapy outcomes. Likewise, optimal breast cancer removal via CAR-redirected immune cells requires detecting safe target antigens, improving CAR structure for ideal immune cell functions, promoting CAR-redirected immune cells filtration to the tumour microenvironment (TME), and increasing the ability of these engineered cells to persist and retain within the immunosuppressive TME. This review provides a concise overview of breast cancer pathogenesis and its hostile TME. We focus on the CAR-T and CAR-NK cells and discuss their significant differences. Finally, we deliver a summary based on recent advancements in the therapeutic capability of CAR-T and CAR-NK cells in treating breast cancer.

RESUMO

Background: Uncertainty intolerance (IU), the tendency to think or react negatively toward uncertain events may have implication on individuals' mental health and psychological wellbeing. The Intolerance of Uncertainty Scale-12 (IU-12) is commonly used across the globe to measure IU, however, its' psychometric properties are yet to be evaluated in Iran with a Persian-speaking population. Therefore, the purpose of this research was to translate and validate the IU-12 among Iranian undergraduate students. Materials and Methods: The multi-stage cluster random sampling was employed to recruit 410 Iranian undergraduate students (260 females) from the Azad University to complete the IU-12, the Depression Anxiety Stress Scale-2, and the Penn State Worry Questionnaire in a cross-sectional design. In this study, face validity, content validity, construct validity, and concurrent validity were measured and Construct Reliability (CR) and Cronbach's alpha were used to measure reliability. Results: The impact score of the translated IU-12 indicated acceptable face validity (value of impact score was greater than 1.5). The value of Content Validity Index (CVI) and the value of Content Validity Ratio (CVR) were above 0.7 and 0.78, respectively. The values of CVI and CVR indicated the items had acceptable content validity and were deemed essential to the measure. The measurement model analysis showed the measure with two subscales had good fit indices (CMIN/df = 2.75, p < 0.01, RMSEA = 0.07, TLI = 0.94, CFI = 0.95, GFI = 0.94). A Confirmatory Factor Analysis (CFA) indicated the scale was composed of the two subscales found in the English-version of the scale (prospective anxiety and inhibitory anxiety), and no items were removed from the scale. The values of CR (0.86) and Cronbach's alphas (0.89) showed the measure had appropriate internal consistency. Conclusion: The findings support the psychometric properties of the Persian version of the IU-12. This scale could be used to reliably and accurately measure uncertainty intolerance among undergraduate students in Iran.

RESUMO

Ovarian cancer (OV) is the second most mortal gynecological malignancy. The oncomarker CA125 has been used as the main ovarian cancer marker for diagnosing and screening ovarian cancer in stages I and II. Therefore, sensitive and real-time detection of CA 125 is critical in ovarian cancer monitoring. Various tests are used to diagnose the CA 125. In recent years, modern methods such as biosensor technology have replaced the old tests for rapid, sensitive and specific detection of CA 125. Various types of biosensors are being developed, among which Surface Plasmon resonance (SPR) biosensors are one of the most important and remarkable types. Considering the importance of SPR biosensors in the diagnosis of enocomarker CA 125, the main focus of the present study is to consolidate the research work from the past two decade to the present. Also, the advantages and challenges in SPR biosensors development have been considered in the detection of CA 125 oncomarker.

RESUMO

BACKGROUND & AIMS: Recent trial studies have found that conjugated linoleic acid (CLA) supplementation beneficially reduces oxidative stress markers but, there is no definitive consensus on this context. The present systematic review and meta-analysis aimed to investigate the effect of CLA supplementation on oxidative stress parameters. METHODS: We searched PubMed, Web of Science, Scopus, Cochrane Library, and Google Scholar databases until September 2021 to identify randomized controlled trials (RCTs) assessing CLA supplementation effects on oxidative markers including malondialdehyde (MDA), 8-isoprostanesF2α (8-iso-PGF2α), and glutathione peroxidase (GPx). Summary estimates and corresponding 95% confidence intervals (CI) were derived via the DerSimonian and Laird method using a random-effects model. RESULTS: A total of 11 RCTs were included. The obtained results show that CLA supplementation caused a significant decrease in MDA concentrations (Hedges's: -0.35; 95% CI: -0.70 to -0.01, P = 0.04, I2 = 62.1%, n = 7), and also significantly increased 8-iso-PGF2α levels (Hedges's: 1.45; 95% CI: 0.98 to 1.91, P˂0.001, I2 = 42.9%, n = 4). However, the results showed that supplementation with CLA did not significantly change the concentrations of GPx (Hedges's: 0.30; 95% CI: -0.04 to 0.64, P = 0.08, I2 = 0.0%, n = 3). CONCLUSION: It seems this supplement can be used as a dietary supplement to improve oxidative stress parameters. However, further studies are required to demonstrate present results.

RESUMO

Leukemia often initiates following dysfunctions in hematopoietic stem cells lineages. Various types of leukemia, including acute lymphoblastic leukemia (ALL), chronic myelogenous leukemia (CML), acute promyelocytic leukemia (APL), and human T-cell leukemia/lymphoma virus type 1 (HTLV-1) can thus call for different diagnosis and treatment options. One of the most important subjects in leukemia is the early detection of the disease for effective therapeutic purposes. In this respect, biosensors detecting the molecules of deoxyribonucleic acid (DNA) as analytes are called genosensors or DNA biosensors. Electrochemical sensors, as the most significant approach, also involve reacting of chemical solutions with sensors to generate electrical signals proportional to analyte concentrations. Biosensors can further help detect cancer cells in the early stages of the disease. Moreover, electrochemical biosensors, developed based on various nanomaterials (NMs), can increase sensitivity to the detection of leukemia-related genes, e.g., BCR/ABL as a fusion gene and promyelocytic leukemia/retinoic acid receptor alpha (PML/RARα). Therefore, the present review reflects on previous studies recruiting different NMs for leukemia detection.
