RESUMEN
OBJECTIVE: Various therapeutic treatments have been prescribed for decreasing the bilirubin level. Massage therapy is one of the neonate treatments for jaundice. The aim of this study is to investigate the effects of combined massage therapy and phototherapy on neonatal jaundice. STUDY DESIGN: This study was performed at Shahid Madani Hospital in the city of Khorramabad in 2016, where 83 healthy full-term infants were enrolled. They were selected through convenience sampling and then were randomly assigned to the intervention and control groups. The control group (n = 43) received phototherapy, whereas infants in the intervention group (n = 40) received 4 days of massage and phototherapy. The serum bilirubin level, frequency of stooling and amount of urination, duration of hospitalization, and feeding frequency were analyzed using SPSS by descriptive and analytical statistics (mixed regression models). RESULTS: Baseline levels of bilirubin were similar between the two groups (p > 0.05). The bilirubin level was measured as 13.4 ± 0.7 mg/dL in the intervention group on day 1. It stood at 14.4 ± 1.5 mg/dL in the control group, which was not statistically significantly different. However, the mean bilirubin level was decreased on day 4 of hospitalization to 7.4 ± 0.56 mg/dL and 9.0 ± 2.3 mg/dL, showing a significant difference decrease in the intervention and control group (p < 0.05), respectively. CONCLUSION: Intervention had a significant role in decreasing the bilirubin level, amount of urination, and duration of hospitalization of full-term infants suffering from hyperbilirubinemia.
RESUMEN
Introduction: Children with intellectual disability (ID) often face challenges in maintaining proper oral hygiene due to their motor, sensory, and intellectual impairments, which can lead to compromised oral health; therefore, there is a need to enhance the oral health status of these populations and establish an effective system for administering preventive interventions. Here, we aimed to evaluate the prevalence of Entamoeba gingivalis and Trichomonas tenax among children with ID in Lorestan province, in Western Iran through parasitological and molecular methods. Methods: The current descriptive investigation involved 215 in children with ID and 215 healthy children (non-ID) who were referred to health facilities in Lorestan province, Iran between October 2022 and March 2024. The prevalence of protozoa in the oral cavity was found through the utilization of both microscopic analysis and conventional polymerase chain reaction (PCR) techniques. Results: The total prevalence of the E. gingivalis and T. tenax in children with ID was found to be 87 (40.5%) and 92 (42.8%) through microscopic and PCR methods, respectively. Among the positive samples, 57 (61.9%) and 35 (38.1%) children tested positive for E. gingivalis and T. tenax, respectively. In contrast, among the 215 non-ID children in the control group, 39 (18.1%) and 42 (19.5%) tested positive by microscopic and PCR methods, respectively. Among positive samples in non-ID children, 23 (54.7%) and 19 (45.3%) children were positive for E. gingivalis and T. tenax, respectively. Multiple logistic regression analysis indicated that residing in urban areas, parental education, monthly family income, and tooth brushing p<0.001) were identified as independent risk factors for oral cavity parasites. Conclusion: This study identified a notable prevalence of oral cavity parasites in children with ID in Lorestan province, Western Iran. It is imperative to recognize the primary risk factors associated with these parasites, particularly inadequate teeth brushing, in order to enhance public and oral health strategies for children with ID. Therefore, pediatric dental professionals should remain vigilant regarding these risk factors to effectively recognize and address oral health issues in this population, thereby mitigating the occurrence of oral diseases and infections.

Background and Aims: Hypertension is the third leading cause of death in the world and is estimated to be increased by about 60% by 2025. Beliefs about hypertension can predict patient adherence to hypertension treatment. This study aims to investigate the perceptions of hypertension and adherence to hypertension treatment among patients in Khorramabad, Iran. Methods: This is a descriptive/analytical study with a cross-sectional design. Participants were 265 patients with a history of hypertension referred to a hospital in Khorramabad, Lorestan Province in western Iran in 2020, who were selected using a convenience sampling method. A demographic form, the brief illness perception questionnaire-revised (BIPQ-R), and Morisky medication adherence scale (MMAS-8) were used for collecting data. The collected data were analyzed in SPSS v.22 software using descriptive statistics, Pearson's correlation test, independent t-test, one-way ANOVA, and regression analysis. Results: The mean scores of BIPQ-R and MMAS-8 were 49.05 ± 15.45 (out of 80) and 3.69 ± 1.62 (out of 8), respectively. There was a significant relationship between the mean scores of MMAS-8 and BIPQ-R in total (p < 0.001). Perceptions of illness consequences (B = 4.59, p = 0.005), personal control (B = 0.190, p = 0.047), and symptoms (B = 1.77, p = 0.005) could significantly predict treatment adherence of patients. In illness perception, there were significant differences among patients with different places of residence (p = 0.032), educational levels (p = 0.001), and employment status (p = 0.010). In treatment adherence, there were significant differences among patients with different places of residence (p = 0.042) and educational levels (p = 0.045). Conclusion: Treatment adherence of hypertensive patients in western Iran is at a low level, while their perception of hypertension is at a moderate level. Clinical physicians are recommended to pay attention to the perception of illness in these patients (especially unemployed and less educated patients living in rural areas) to improve their adherence to treatment and blood pressure control.
RESUMEN
Background: This survey was designed to study the molecular epidemiology and risk factors of Entamoeba gingivalis and Trichomonas tenax in children with underlying malignancies and those on chemotherapy in Lorestan province, West of Iran. Methods: The present cross-sectional descriptive study was performed on children who suffering from different types of malignancies or receiving treatment by chemotherapy referring to oncology section of hospitals of Lorestan Province, Iran during May 2021 to April 2022. The frequency of oral cavity protozoa was investigated using microscopic and conventional polymerase chain reaction (PCR). Results: E. gingivalis and T. tenax parasites were found in 23 (25.5%) by microscopic method and 28 (31.1%) using PCR in children with malignancy. Among positive samples, 20 (71.4%) were infected with E. gingivalis; whereas 8 (28.6%) of the participants were positive for T. tenax. In the multivariate model, living in rural regions (OR= 3.437; 95% CI= 1.22-9.63; p=0.019) and using mouthwash (OR= 0.082; 95% CI= 0.018-0.37; p<0.001) were significantly related with the frequency of oral cavity parasites. Conclusion: Our results showed the high frequency of oral cavity parasites in children who suffering malignancies or receiving treatment by chemotherapy in Lorestan province, Iran. The awareness of the main risk factors for oral cavity parasites particularly using mouthwash is necessary in improving public and oral health strategies in children with cancer. Consequently, oncologist and dental practitioners must be aware to identify and manage oral health concerns in in children who suffering from different types of malignancies to prevent the oral diseases and infections.
RESUMEN
Renal disorders are able to make patients more susceptible to infections, including those caused oral cavity infections. Today, it has been proven that during end stage renal failure, hemodialysis results in acquired immune response defects through failings of humoral and cell-mediated immune. This survey was intended to assess the molecular epidemiology and associated risk factors of Entamoeba gingivalis and Trichomonas tenax as the main oral cavity protozoa in hemodialysis patients in Lorestan Province, western Iran. The investigation was performed on 73 hemodialysis patients referring to hemodialysis centers of Lorestan Province, Iran during May 2021 to February 2022. The frequency of oral cavity protozoa was investigated using microscopic and conventional polymerase chain reaction (PCR). A provided questionnaire with a number of demographical information and related risk factors was completed for each patient. The results showed that E. gingivalis and T. tenax parasites were found in 18 (24.6%) and 20 (27.4%) of the hemodialysis participants by microscopic and PCR test, respectively. Among samples, 13 (17.8%) of the hemodialysis participants were infected with E. gingivalis; whereas 7 (9.6%) of the participants were positive for T. tenax. No significant association was reported between gender, age, education, flossing, use of mouthwash, and prevalence of oral protozoa in hemodialysis participants. However, a significant correlation was observed among between living in rural regions (OR = 13.16; 95% CI = 2.64-56.81; p = 0.002), brushing teeth (OR = 8.51; 95% CI = 1.71-42.3; p = 0.009) and prevalence of oral protozoa in hemodialysis participants. The findings of these epidemiological study clearly showed the high frequency of oral cavity parasites in hemodialysis patients in Lorestan Province, Western Iran. Awareness of the main risk factors for oral cavity parasites particularly teeth brushing is necessary in refining public and oral health policies in hemodialysis patients. Consequently, dental practitioners, nephrologist, and urologist must be alert of these risk factors to carefully identify and achieve oral health concerns in hemodialysis patients to prevent the oral diseases and infections.
RESUMEN
Background/purpose: Due to the importance of social support in pregnant women, especially those with gestational diabetes that cause anxiety and stress in them and requires effective and enough attention, this study aims to assess perceived social support of pregnant women with gestational diabetes in western Iran compared to healthy controls and its relationship with their perceived anxiety. Methods: This is a descriptive/analytical study with a cross-sectional design conducted on 180 pregnant women with gestational diabetes (n = 89) and without gestational diabetes (n = 91) referred to the obstetrics and gynecology clinics of two hospitals (Asalian and Shahid Rahimi) in Khorramabad, western Iran. Data collection tools were a demographic checklist, the Multidimensional Scale of Perceived Social Support (MSPSS), and the Beck Anxiety Inventory (BAI). Collected data were analyzed in SPSS v.20 software using chi square test, independent t-test, one-way ANOVA, and Pearson correlation test. Results: The difference between the two groups was significant in terms of perceived support from family (p = 0.001), perceived support from friends (p = 0.006), and anxiety (p = 0.047). Pearson correlation test results showed a significant negative relationship between the scores of MSPSS and BAI in patients (r= -0.329, p = 0.001) and controls (r=-0.204, p = 0.006). There was a significant difference in the MSPSS score among diabetic women in terms of having fetal macrosomia (p = 0.005), occupation (p = 0.003), education (p = 0.001), and frequency of pregnancy (p = 0.010). Conclusions: The perceived social support level is higher in diabetic pregnant women compared to healthy peers in western Iran. Improvement of social support from family and friends can reduce the anxiety of pregnant women with/without diabetes.
RESUMEN
BACKGROUND: Health-promoting behaviors can affect the psychological and physical consequences of hypertension. For the prevention and control of hypertension, lifestyle modification has been recommended. This study aimed to investigate the health-promoting behaviors of patients with hypertensive heart disease in Iran and compare them with those of healthy people. MATERIALS AND METHODS: This was a descriptive comparative study with cross-sectional design. Participants were 141 patients with hypertensive heart disease (mean age = 39 ± 10.2 years) referred to the cardiac clinic of Madani Hospital in Khorramabad, Iran, and 141 healthy people selected from those referred to the hospital. The Persian version of the revised Health-Promoting Lifestyle Profile-II (HPLP-II) was used to evaluate the health-promoting behaviors of participants. After collecting data, they were analyzed in SPSS v. 22 software using descriptive statistics and statistical tests including independent t-test and one-way ANOVA. RESULTS: The overall HPLP-II score was 142.34 ± 30.48 in patients and 150.52 ± 37.07 in controls. The highest and lowest HPLP-II dimension scores in both groups were related to health responsibility and stress management dimensions. There was a significant difference between groups only in dimensions of nutrition (P = 0.017) and physical activity (P = 0.016), and in the overall score (P = 0.044), whose scores were lower in patients compared to controls. The difference in HPLP-II score of patients with different demographic characteristics (marital status, place of residence, gender, age, educational level, and occupation) was not statistically significant. CONCLUSION: Patients with heart disease caused by high blood pressure in Iran have poorer diet and physical activity compared to healthy people. Educational interventions with a focus on the importance of dietary regime and exercise are recommended for them.

OBJECTIVE: Functional constipation (FC) and Gastroesophageal Reflux Disease (GERD) are common gastrointestinal disorders in children. The aim of this study is to investigate the correlation between functional constipation and GERD in children. METHODS: In this cross-sectional study, a total of 82 children aged <16 years who referred to the pediatric gastroenterology clinic of (XXX) and were diagnosed with functional constipation according to ROME III criteria, and gastroesophageal reflux disease according to clinical history and DeMeester Score. Questionnaire was used to obtain the data regarding age, sex, cause of the visit, presence or absence of any symptom was noted, clinical examinations and difficulty in defecation. RESULTS: Of the 82 children with FC and GERD, 45 were boys and 37 were girls. Among children with FC and GERD, FC was reported in 50 (61%) cases prior to the onset of GERD, whereas 32 (39%) of the children had reflux before FC. The mean age of participants presented with FC was 5.66 ± 3.52 and that of GERD was 5.24 ± 2.83. The difference in mean age was not statistically significant. Of the children with gastroesophageal reflux disease, there were 13 (40.6%) males and 19 females while 32 (64%) males and 18 females had FC and the gender-based difference was statistically significant between the 2 groups. CONCLUSION: The prevalence of functional constipation in children was higher than gastroesophageal reflux disease. Gastroesophageal reflux disease and functional constipation should be simultaneously considered for therapeutic interventions and patients with functional digestive diseases should be monitored and followed-up.
RESUMEN
Background: We aimed to study the frequency and risk factors of oral cavity protozoa (Trichomonas tenax and Entamoeba gingivalis) in pregnant women in Lorestan province, western Iran. Methods: The current cross-sectional descriptive work was performed on 200 pregnant women referring to health centers of Lorestan Province, Iran during August 2021 to February 2022. Two specimens were obtained from each women by means of sterile swabs from saliva and dental plaques. The frequency of oral cavity protozoa was investigated using microscopic and conventional polymerase chain reaction (PCR). Results: E. gingivalis and T. tenax parasites were found in 41 (20.5%) and 46 (23%) of the pregnant women by microscopic and PCR test, respectively. Among positive samples, 29 (63.1%) of the pregnant women were infected with E. gingivalis; whereas 19 (36.9%) of the participants were positive for T. tenax. In the multivariate model, living in rural regions (p < 0.001) and brushing teeth (p = 0.021) were considerably linked with the prevalence of oral cavity parasites. Conclusion: The current study evidently exhibited the high frequency of oral cavity parasites (E. gingivalis and T. tenax) in pregnant women in Lorestan province, Western Iran. Awareness of the main risk factors for oral cavity parasites especially teeth brushing is necessary in refining public and oral health approaches in pregnant women. Thus, dental practitioners and gynecologists must be alert of these risk factors to carefully identify and manage oral health concerns in pregnant women to prevent the oral diseases and infections.
RESUMEN
OBJECTIVES: This study aimed to compare home visits and telephone follow-up effectiveness on patients' self-efficacy undergoing Coro-nary Artery Bypass Graft Surgery -CABG- and caregivers' burden. METHODS: In this randomized clinical trial, 114 patients undergoing CABG were assigned to the three groups of home visits, telephone follow-up, and control based on the stratified block randomization. The self-management program of the home visit group included four face-to-face 60-minute training sessions once a week, and for the telephone follow-up group, four 30-minute telephone counseling sessions twice each week for a month. The control group received routine care. Data were collected using the cardiac rehabilitation self-efficacy questionnaire and the caregiver burden scale before and after the interven-tion. RESULTS: Before the study, there were no statistically significant differences between the three groups in terms of the means of self-efficacy and caregiver burden scores. However, there was a statistically significant difference between the home visit and control groups (p<0.001) and between the telephone follow-up and control groups (p<0.001) after the intervention, with in-creased self-efficacy and reduced caregiver burden reported. In contrast, there was no significant difference between the home visit and telephone follow-up groups regarding self-efficacy and caregiver burden scores. CONCLUSIONS: Both methods of self-management education have similar effectiveness in increasing self-efficacy and reducing the care-giver burden after discharge for patients who have undergone CABG.
RESUMEN
BACKGROUND: In recent years, magnetic nanoparticles (NMP) as novel materials have been widely used for biomedical, diagnostic and therapeutic purposes like microbial infection therapy. The purpose of this study is to synthesize PO coated iron oxide magnetic nanoparticles (Fe3O4@PO NPs) and their anti-leishmanial effects in vitro and in vivo against cutaneous leishmaniasis. METHODS: Fe3O4 magnetic nanoparticles were synthesized by the coprecipitation of Fe2 + and Fe3 + ions and used as a nanocarrier for the production of Fe3O4@PO NPs. The in vitro antileishmanial effects of PO-coated Fe3O4 NPs and Fe3O4 NPs (10-200 µg/mL) was determined against the intracellular amastigotes of Leishmania major (MRHO/IR/75/ER) and, then, examined on cutaneous leishmaniasis induced in male BALB/c mice by L. major. The rate of infectivity, production of nitric oxide (NO), and cytotoxic activates of Fe3O4 NPs and Fe3O4@PO NPs on J774-A1 macrophage cells were determined. RESULTS: The size scattering of the Fe3O4 NPs and Fe3O4@PO NPs were in the range among 1-40 and 5-55 nm, respectively. The obtained IC50 values were 62.3 ± 2.15 µg/mL, 31.3 ± 2.26 µg/mL, and 52.6 ± 2.15 µg/mL for the Fe3O4 NPs and Fe3O4@PO NPs, and MA, respectively. The results revealed that the mean number of parasites and the mean diameter of the lesions was considerably (p < 0.05) decreased in the infected mice treated with Fe3O4 NPs and Fe3O4@PO NPs. The Fe3O4 NPs and Fe3O4@PO NPs significantly (p < 0.05) prompted the production of NO as a dose-dependent manner. The promastigotes pre-incubated in Fe3O4 NPs and Fe3O4@PO NPs at the concentration of 5 µg/mL had the ability to infect only 41.7% and 28.3% of the macrophages cells. The selectivity index of greater than 10 for Fe3O4 NPs and Fe3O4@PO NPs showed its safety to the J774-A1 macrophage cells and specificity to the parasite. CONCLUSION: The results of this survey indicated the high potency of Fe3O4@PO NPs to inhibit the growth of amastigote forms of L. major as well as recovery and improvement CL induced by L. major in BALB/c mice without significant cytotoxicity. The results also indicated that, although the possible anti-leishmanial mechanisms of Fe3O4@PO NPs have not been clearly understood, however, the triggering of NO may be considered as one of the possible anti-leishmanial mechanisms of these nanoparticles. However, additional studies, in particular in clinical contexts, are mandatory.

BACKGROUND: The current chemotherapy agents against various forms of leishmaniasis have some problems and side effects, including high toxicity, high cost, and the emergence of resistant strains. Here, we aimed to review the preclinical studies (in vitro and in vivo) on the anti-leishmanial activity of chitosan and chitosan-based particles against Leishmania spp. METHODS: This study was conducted based on the 06-PRISMA guidelines and registered in the CAMARADES-NC3Rs Preclinical Systematic Review and Meta-Analysis Facility (SyRF) database. Various English databases such as PubMed, Google Scholar, Web of Science, EBSCO, ScienceDirect, and Scopus were used to find the publications related to the anti-leishmanial effects of chitosan and its derivatives and other pharmaceutical formulations, without a date limitation, to find all the published articles. The keywords included "chitosan", "chitosan nanoparticles", "anti-leishmanial", "Leishmania", "leishmaniasis", "cutaneous leishmaniasis", "visceral leishmaniasis", "in vitro", and "in vivo". The language for data collection were limited to English. RESULTS: Of 2669 papers, 25 papers, including 7 in vitro (28.0%), 7 in vivo (28.0%), and 11 in vitro/in vivo (44.0%) studies conducted up to 2020 met the inclusion criteria for discussion in this systematic review. The most common species of Leishmania used in these studies were L. major (12, 48.0%), L. donovani (7, 28.0%), and L. amazonensis (4, 16.80%). In vivo, the most used animals were BALB/c mice (11, 61.1%) followed by hamsters (6, 33.3%) and Wistar rats (1, 5.5%), respectively. In vitro, the most used Leishmania form was amastigote (8, 44.4%), followed by promastigote (4, 22.2%), and both forms promastigote/amastigote (6, 33.3%). CONCLUSION: According to the literature, different types of drugs based on chitosan and their derivatives demonstrated considerable in vitro and in vivo anti-leishmanial activity against various Leishmania spp. Based on the findings of this review study, chitosan and its derivatives could be considered as an alternative and complementary source of valuable components against leishmaniasis with a high safety index. Nevertheless, more investigations are required to elaborate on this result, mainly in clinical settings.
RESUMEN
BACKGROUND: In recent years, the focus on nanotechnological methods in medicine, especially in the treatment of microbial infections, has increased rapidly. AIM: The present study aims to evaluate in vitro and in vivo antileishmanial effects of copper nanoparticles (CuNPs) green synthesized by Capparis spinosa fruit extract alone and combined with meglumine antimoniate (MA). METHODS: CuNPs were green synthesized by C. spinosa methanolic extract. The in vitro antileishmanial activity of CuNPs (10-200 µg/mL) or MA alone (10-200 µg/mL), and various concentrations of MA (10-200 µg/mL) along with 20 µg/mL of CuNPs, was assessed against the Leishmania major (MRHO/IR/75/ER) amastigote forms and, then tested on cutaneous leishmaniasis induced in male BALB/c mice by L. major. Moreover, infectivity rate, nitric oxide (NO) production, and cytotoxic effects of CuNPs on J774-A1 cells were evaluated. RESULTS: Scanning electron microscopy showed that the particle size of CuNPs was 17 to 41 nm. The results demonstrated that CuNPs, especially combined with MA, significantly (p < 0.001) inhibited the growth rate of L. major amastigotes and triggered the production of NO (p < 0.05) in a dose-dependent manner. CuNPs also had no significant cytotoxicity in J774 cells. The mean number of parasites was significantly (p < 0.05) reduced in the infected mice treated with CuNPs, especially combined with MA in a dose-dependent response. The mean diameter of the lesions decreased by 43 and 58 mm after the treatment with concentrations of 100 and 200 mg/mL of CuNPs, respectively. CONCLUSION: The findings of the present study demonstrated the high potency and synergistic effect of CuNPs alone and combined with MA in inhibiting the growth of amastigote forms of L. major, as well as recovery and improving cutaneous leishmaniasis (CL) induced by L. major in BALB/c mice. Additionally, supplementary studies, especially in clinical settings, are required.
RESUMEN
BACKGROUND/AIM: Adolescent girls' concerns about their body images can negatively affect their social and academic performance. This study aimed to determine the prevalence of body image concern (BIC) in adolescent schoolgirls in Iran and its risk factors. PATIENTS AND METHODS: This epidemiological study with cross-sectional design was conducted in 2018 on 396 middle schoolgirls aged 12-17 years (mean age = 14 years) living in Khorramabad, Iran. For screening BIC, the Persian version of BIC inventory (BICI) was used. Their birth order, school grade, school type, father's education, and household income were also recorded. Collected data were analyzed in SPSS v. 18 software using descriptive statistics and Chi-square test. RESULTS: Of 396 girls, 106 (26.8%) had BIC, 89 (84%) reported moderate BIC, and 17 (16%) severe BIC. Their mean BICI score was 40.84 ± 12.93 (out of 42). Most of them reported to spend a significant amount of time checking their appearance in the mirror (n = 81, 20.5%) and examining flaws in their appearance (n = 74, 18.7%). A few of them were embarrassed to leave the house because of the appearance and avoided from looking at the appearance in the mirror (n = 6, 1.5%). There was no significant difference in BIC severity in terms of birth order, school grade, school type, father's education, and household income factors (P > 0.05). CONCLUSION: The prevalence of BIC among schoolgirls in Iran is high. Appropriate therapeutic interventions should be carried out to improve their quality of life, mental health, and self-esteem to reduce the BIC prevalence.
RESUMEN
AIM: This study aimed to investigate the prevalence of thyroid disease (TD) in untreated CD patients and to evaluate the effect of gender and age on its prevalence. BACKGROUND: Celiac disease (CD) is a form of intestinal malabsorption syndrome which is closely related to endocrine disorders, especially autoimmune thyroid disease and diabetes. The prevalence of TD is possibly high among patients with CD which necessitates the need for screening for TD among them. METHODS: This comparative cross-sectional study was conducted on 288 consecutive untreated patients with CD (mean age, 27.9±14) and 250 controls (mean age, 29.01±13.15) referred for endoscopy in a hospital located in Iran. Thyroid function was evaluated by measuring T3, T4, and TSH levels using ELISA technique, and testing anti-thyroperoxidase (anti-TPO) antibodies through electrochemiluminescence method. Data analysis was conducted in SPSS v.22 software using descriptive statistics and chi-squared test. RESULTS: Thyroid disease prevalence was 4-fold higher in patients than in controls (13.6% vs. 3.2%, p<0.05). Hypothyroidism was diagnosed in 30 patients and 7 controls, while hyperthyroidism was observed in 9 patients and in one control. Chi-squared test results reported a significant difference in TD prevalence between patients and controls based on gender and age (p<0.05). In both groups, women were signiï¬cantly more affected than men, and the TD prevalence was higher in younger patients compared to adults. CONCLUSION: There was a strong association between thyroid dysfunction and CD. In this regard, it is necessary to screen patients for TD.
RESUMEN
PURPOSE: Colorectal cancer is the third-most commonly occurring cancer in developed countries. Hydroxytyrosol is a potent antioxidant that has several activities, such as oxidative-stress control, inhibition of cell proliferation, and induction of apoptosis. In this study, the effect of hydroxytyrosol on the expression of genes effective in apoptosis - BAX, BCL2, CASP3, P53, PPAR G, and NFE2L2 - and antioxidant-enzyme activity in LS180 cells of human colorectal cancer was investigated. METHODS: The human colorectal cancer cell line LS180 was treated with different concentrations of hydroxytyrosol for 24 hours. Expression of BAX, BCL2, CASP3, NFE2L2, PPAR G, and P53 was investigated using real-time PCR. The activity of antioxidant and malondialdehyde enzymes was measured by calorimetric methods. RESULTS: Analysis of gene expression showed that hydroxytyrosol significantly increased the expression of CASP3 and the BAX:BCL2 ratio in treatment groups compared to the control (P<0.05). Also, hydroxytyrosol significantly reduced the expression of the NFE2L2 gene (P<0.05). Calorimetric analysis showed that hydroxytyrosol increased activity of the antioxidant enzymes catalase, superoxide dismutase, and glutathione peroxidase in treatment groups significantly more than the control group and reduced thiobarbituric acid-reactive substances on an oxidative stress index (P<0.05). CONCLUSION: Hydroxytyrosol may induce apoptosis in colorectal cancer cells by increasing the expression of CASP3 gene and increasing the BAX:BCL2 ratio. Also, hydroxytyrosol may increase the activity of antioxidant enzymes and reduce the proliferation of LS180 cells by changing the antioxidant-defense system in cancer cells.
RESUMEN
Since there is no potential, effective vaccine available, treatment is the only controlling option against hydatid cyst or cystic echinococcosis (CE). This study was designed to systematically review the in vitro, in vivo, and ex vivo effects of nanoparticles against hydatid cyst. The study was carried out based on the 06- PRISMA guideline and registered in the CAMARADES-NC3Rs Preclinical Systematic Review and Meta-analysis Facility (SyRF) database. The search was performed in five English databases, including Scopus, PubMed, Web of Science, EMBASE, and Google Scholar without time limitation for publications around the world about the protoscolicdal effects of all the organic and inorganic nanoparticles without date limitation in order to identify all the published articles (in vitro, in vivo, and ex vivo). The searched words and terms were: "nanoparticles", "hydatid cyst", "protoscoleces", "cystic echinococcosis", "metal nanoparticles", "organic nanoparticles", "inorganic nanoparticles, "in vitro", ex vivo", "in vivo". Out of 925 papers, 29 papers including 15 in vitro (51.7%), 6 in vivo (20.7%), ex vivo 2 (6.9%), and 6 in vitro/in vivo (20.7%) up to 2020 met the inclusion criteria for discussion in this systematic review. The results demonstrated the most widely used nanoparticles in the studies were metal nanoparticles such as selenium, silver, gold, zinc, copper, iron nanoparticles (n = 8, 28.6%), and metal oxide nanoparticles such as zinc oxide, titanium dioxide, cerium oxide, zirconium dioxide, and silicon dioxide (n = 8, 28.6%), followed by polymeric nanoparticles such as chitosan and chitosan-based nanoparticles (n = 7, 25.0%). The results of this review showed the high efficacy of a wide range of organic and inorganic NPs against CE, indicating that nanoparticles could be considered as an alternative and complementary resource for CE treatment. The results demonstrated that the most widely used nanoparticles for hydatid cyst treatment were metal nanoparticles and metal oxide nanoparticles, followed by polymeric nanoparticles. We found that the most compatible drugs with nanoparticles were albendazole, followed by praziquantel and flubendazole, indicating a deeper understanding about the synergistic effects of nanoparticles and the present anti-parasitic drugs for treating hydatid cysts. The important point about using these nanoparticles is their toxicity; therefore, cytotoxicity as well as acute and chronic toxicities of these nanoparticles should be considered in particular. As a limitation, in the present study, although most of the studies have been performed in vitro, more studies are needed to confirm the effect of these nanoparticles as well as their exact mechanisms in the hydatid cyst treatment, especially in animal models and clinical settings.
RESUMEN
BACKGROUND: One of the major problems in wound healing is scar formation; however, there are few ways to prevent or treat it. Different species of Achillea are used to treat wounds in folk medicine from the past but there are few studies on the effect of it on wound healing and inhibition of scar formation. The aim of this study was to investigate the effect of Achillea biebersteinii Afan hydroethanolic extract on the expression of TGFß1 and bFGF as effective growth factors of wound healing in mouse embryonic fibroblast cells. METHODS: Mouse embryonic fibroblast cells were exposed to different concentrations of Achillea extract at two different time (12 and 24 hr); the expression of TGFß1 and bFGF was performed by real-time-PCR and ELISA at the level of gene and protein. RESULTS: It was observed that the plant extract at 5 and 10 µg/ml downregulated the expression of TGFß1 and upregulated the expression of bFGF at the level of gene and protein. CONCLUSION: The results showed that the pattern of changes in the expression of TGFß1 and bFGF by Achillea biebersteinni Afan extract may inhibit scar formation.

BACKGROUND/AIM: Parents have an important role to play in supporting adolescents with type 1 diabetes mellitus (T1DM). Their education and occupation are important factors for the management of this disease. This study aimed to investigate the parental support that Iranian adolescents with T1DM experience and to examine the effect of parents' education and occupation on adolescents' perceived the parental support and metabolic control. METHODS: This is a cross-sectional survey. The participants were 98 adolescents (aged 11-18 years) with T1DM referred to Endocrinology Clinics of Shahid Rahimi and Shahid Madani hospitals in Khorramabad, Iran, in 2016. For evaluating the adolescents' perceptions of parental support, the family version of Diabetes Social Support Questionnaire was employed. It measures in five diabetic care areas (insulin administration, blood testing, meal planning, exercise, and emotional support). Data were analyzed in SPSS version 22 software using descriptive statistics and inferential tests including Pearson correlation test, ANOVA, and independent t-test. RESULTS: The parents' educational level had a significant relationship with adolescents' perceived parental support and hemoglobin A1c (HbA1c) level (P < 0.05). Occupation of father had no significant influence on his supportive behavior and HbA1c level in adolescents, but mother's occupation significantly influenced them (P < 0.05). In adolescents with higher perceived parental support, the mean HbA1c was lower. CONCLUSIONS: Parents with higher educational level can improve the metabolic control and provide better meal planning in adolescents with T1DM.
