The effectiveness of training mothers with regard to pediculosis preventive behavior among school students: A Protection Motivation Theory study.

BACKGROUND OBJECTIVES: Lice infestation is considered as a reemerging problem as well as a health challenge. Based on Protection Motivation Theory, the present study was conducted to investigate the effectiveness of training mothers in regard to pediculosis preventive behavior among school students. METHODS: In a critical trial, 180 mothers of primary school daughters were assessed in two study groups in the Iranian city of Qom in 2021. They received training intervention in a course of four ninety-minute sessions during four weeks. After six months, the post-test questionnaire and the checklist were completed by them. The data were gathered using a valid and reliable questionnaire. Finally, data analysis was performed using SPSS 20. RESULTS: After the training intervention, a significant difference was observed within the intervention group in scores of the prevention motivation constructs (P<0.001). Besides, there was a significant difference between the mean scores of the preventive behavior of the mothers and daughters in the intervention group before the training intervention and six months after it (P<0.001). However, no significant difference was seen before and after the intervention in the control group (P>0.05). Additionally, no significant differences were observed between the intervention and control groups (P<0.001) in terms of comparing the mean score differences of all the constructs of protection motivation theory, the mothers' behavior and the daughters' behavior checklist. INTERPRETATION CONCLUSION: The results indicate the effectiveness of training mothers based on Protection Motivation Theory in regard to pediculosis. Therefore, it seems that in developing training programs, utilizing this theory could prove useful to bring about changes in the individuals' behavior regarding the prevention of pediculosis.

Evaluation of the prevalence of Aeromonas spp., Campylobacter spp., and Clostridioides difficile in immunocompromised children with diarrhea.

AIM: Diarrhea is a common disease in immunocompromised patients and can be associated with greater morbidity and even mortality. Therefore, the present study was designed to determine the prevalence of Aeromonas spp., Campylobacter spp., and C. difficile among immunocompromised children. METHODS: This study was conducted on 130 stool samples from patients with diarrhea who had defects in the immune system and were referred to Hazrat Masoumeh Children's Hospital in Qom. Demographic information, clinical symptoms, immune status, and duration of chemotherapy were also recorded for each child. DNAs were extracted from the stool, and then direct PCR assays were done by specific primers for the detection of Aeromonas spp., Campylobacter spp., and toxigenic C. difficile, including tcdA/B and cdtA/B genes. Co-infection in patients was also evaluated. RESULTS: 60.8% and 39.2% were male and female, respectively, with a m ± SD age of 56.72 ± 40.49 months. Most cases of immunocompromised states were related to Acute Lymphocytic Leukemia (77.7%) and Non-Hodgkin Lymphoma (14.6%). 93.1% of patients were undergoing chemotherapy during the study. Among patients, most clinical symptoms were related to bloody diarrhea (98.5%) and fever (92.3%). Based on PCR, 14.6, 9.2, and 1.5% were positive for Aeromonas spp., C. difficile, and C. jejuni, respectively. Among the C. difficile-positive cases, the tcdA gene was only detected in one patient. In total, three co-infections were identified, which included Aeromonas spp./C. difficile (tcdA+), C. jejuni/C. difficile, and C. jejuni/Aeromonas spp. CONCLUSIONS: This is the first study in Iran to investigate the simultaneous prevalence of some pathogens in immunocompromised children with diarrhea. Because Aeromonas spp., Campylobacter spp., and C. difficile are not routinely detected in some laboratories, infections caused by them are underappreciated in the clinic. Our results showed that these pathogens are present in our region and can cause gastroenteritis in children, especially those with underlying diseases. Therefore, increasing the level of hygiene in some areas and controlling bacterial diarrheal diseases should be given more attention by health officials.

Monitoring the utilization and effectiveness of Iron and Vitamin D supplementations program and its predictive factors in high schools' girls in Qom, Iran.

Background: Iron and Vitamin D3 deficiency is one of the major global health problems in teenagers and adolescent population. This study was aimed to monitor the utilization and predictive factors of Iron and Vitamin D Supplementations Program (IVDSP) in high schools' girls. Methods: In a cross sectional study, the pattern of Iron and D3 consumption based on IVDSP on 400 high schools' girl in Qom, Iran assesses. Data collection was used by a reliable and standard researcher based questionnaire and daily, weekly, monthly and seasonally consumption of complementary minerals in schools were gathered. Data analysis conducted using SPSS version 20 (SPSS Inc., Chicago, IL, USA) by chi square, independent t-test and multivariate logistic regression. Results: The mean age of subjects was 15.14 ± 1.52 years and ranged from 12 to 18 years old. The total weekly prevalence of D3 and Iron consumption in high schools' girls was calculated 36.73% and the weekly prevalence of Iron and monthly prevalence of Vitamin D3 consumption was 33.75% and 40.5%, respectively. The most common causes of non-consumption were bad taste 49.31%, Iranian made drug 20.27%, drug sensitivity 19.82% and drug interaction 10.60%, respectively. Conclusions: The inadequate and incomplete rate of IVDSP in Qom was high and more than 60% of distributed supplementations have been wasted. Results showed that students who were participated in educational orientation classes were more successful and eager in Iron and Vitamin D3 consumption. Therefore, more educational explanatory interventions for both students and her parents recommended to increase the efficiency of the program.

Comparison of the Effects of Govarcin Herbal Capsule and Metoclopramide for Alleviating Gastrointestinal Symptoms in Patients with Functional Dyspepsia: A Randomized Double-blind Clinical Trial.

BACKGROUND: Functional dyspepsia (FD) is felt as a discomfort or pain on the center line or upper abdomen. In this study, we aimed to compare the effects of Govarcin herbal capsule and Metoclopramide for alleviating gastrointestinal symptoms in patients with FD. METHODS: Totally, 106 patients enrolled in a double-blind, clinical trial study. The participants had FD and were divided into two groups receiving Govarcin and Metoclopramide by block randomization. The patients were treated for four weeks, taking one Govarcin capsule or Metoclopramide tablet after each meal. The rate of improvement in patients was assessed by mitigation of clinical symptoms, including epigastric pain, fullness, discomfort, nausea, vomiting and heartburn. Also, before and after intervention, we used Nepin questionnaire and ROME III. SPSS statistics 25 software was used for data analyzing. RESULTS: Clinical symptom score changes between Govarcin and Metoclopramide patients' groups showed that there was no significant difference in any of the clinical symptom scores (except for heartburn, p-value=0.012) between the study groups. Nepean score in Govarcin group before and after treatment were 19.3±4.8 and 8.9±2.8, respectively (p-value<0.001). For Metoclopramide group, these values were 19.8±3.5 and 9.4±2.1 respectively (p-value<0.001). No significant difference was found in terms of Nepean score between the Govarcin and Metoclopramide groups (p-value=0.995). CONCLUSION: Govarcin herbal capsule can be used to remedy symptoms in patients with FD. It seems that Govarcin is as effective as Metoclopramide in fighting symptoms of FD as no significant difference in efficacy has been demonstrated between them.

Severe Acute Respiratory Syndrome Coronavirus 2 Infection Symptoms in Pregnancy and Maternal and Neonatal Complications Due to COVID-19: A Systematic Review.

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in pregnant women is associated with severe maternal and neonatal complications including maternal and newborn death. Aims: This review aimed to assess the SARS-CoV-2 infection symptoms during pregnancy as well as maternal and neonatal complications in Iran. Settings and Design: A developing and low-income country and a systematic review. Materials and Methods: International scientific databases including PubMed, Web of Science, Scopus and Google Scholar were searched in a systematic review manner. Two independent researchers were checked and identified articles from September 2019 to September 2022 based on eligibility criteria and quality appraisal. The results of review were reported in two sections including maternal and neonatal outcomes. Statistical Analysis Used: Descriptive statistics was used for statistical analysis. Results: Seventeen studies including 870 pregnant mothers with COVID-19 met the eligibility criteria and were reviewed. The main maternal consequences of COVID-19 were intensive care unit (ICU) admission, pre-term delivery, maternal death, pre-mature rupture of membranes, pre-eclampsia, intrauterine growth retardation and stillbirth. Neonatal ICU admission, newborn death, neonatal sepsis, low birth weight and respiratory distress syndrome, tachypnoea, asphyxia and pneumothorax were the most common outcomes of COVID-19 infection in offspring of pregnant subjects. Conclusion: Pregnant mothers with COVID-19 infection are at higher risk of being admitted to the ICU and mechanical ventilation and consequently maternal and neonatal death. Comparing the maternal and foetal consequences in different ethnicities, regions and countries may be related to the socioeconomic status of people and should be considered with respect to different determines. Moreover, the maternal and neonatal complications due to COVID-19 infection in Iran and other developing countries seem to be higher than other countries.

Cancer resilience in parents of children with cancer; the role of general health and self-efficacy on resiliency.

Introduction: Cancer in children affect their parents to some stress and worries during treatment process. This study aimed to assess the parental adjustment on the resiliency of parents of children with cancer and its relationship with social support, self-efficacy, and general health. Materials and Methods: In a cross-sectional study, 107 parents of children with cancer were selected by convenience sampling method from the Oncology Departments of Qom Hospitals, Iran. Standard questionnaires including Phillips Social Support, Corner Davidson Resilience, Sheerer Self-Efficacy Inventory, and General Health Questionnaire (GHQ-28) were used for data collection. Pearson's correlation coefficient, Chi-square test, t-test, and multivariate linear regression were used for data analysis in SPSS software. Results: A significant correlation was observed between cancer resilience and social support score (r = 0.285). Multivariate regression model Showed that social support was the most important predictor of cancer resilience (ß =0.723, P = 0.045). In addition, self efficacy (ß =0.356, P = 0.005) showed a direct relationship with cancer resilience. Nevertheless, an inverse association (ß = -0.351, P = 0.025) was observed between GHQ score and cancer resilience in parents of children with cancer. Conclusion: Cancer resilience in families of children with cancer is significantly associated with higher social support, more self-efficacy, and better general health. Interventional programs aimed at increasing family resilience and reducing stress by increasing the social support and self-efficacy in patients' families are helpful and necessary.

Measles Elimination Successful and Its Relevant Challenges in Iran.

Measles is an infectious childhood disease with some death annually. The expansion of the coverage of vaccination plan has significantly reduced the mortality rate of this disease. Given that the endemic measles virus is not transmitted in the country and based on Regional Verification Commission (RVC) for Measles and Rubella Elimination has declared that measles and rubella have been eliminated in three countries of Eastern Mediterranean Region including Islamic Republic of Iran, Bahrain, and Oman. Therefore, to continue and preventing from reemerging of measles in Iran, it is essential to maintaining the immunization programs, diagnose, and investigate all suspicious cases and outbreaks. This article investigates the challenges facing to measles after elimination declaration in Iran. However, the elimination of these diseases to be sustainable needs a vigorous case identification protocol and contact follow up.

Prevalence and association of temporomandibular disorders with malocclusion and anxiety in children and adolescents: a cross-sectional observational study.

The aims of this study were to evaluate the prevalence of temporomandibular disorders (TMDs) in children between 6 and 12 years of age in the city of Qom, Iran, and explore the associations between TMDs and both malocclusion and anxiety. This study was conducted in 193 children who were assessed via interview, clinical examination, and the parent version of the Spence Children's Anxiety Scale. Clinical examinations consisted of assessment of asymmetry, joint sounds, jaw movements (functional shift, temporomandibular joint pain on opening, limitations on mouth opening, and mandibular deviation from midline on mouth opening), and masticatory muscles (sensitivity of masseter and temporalis muscles on palpation and dysfunction of pterygoid muscles). The presence of malocclusion and parafunctional habits were also evaluated. The data were analyzed using chi-square and independent t tests. The associations between anxiety and the quantitative variables of the study were analyzed with the Pearson correlation coefficient. The total prevalence of TMDs in this sample was 17.1%. Most children with TMDs had a moderate anxiety level, and the anxiety score had a significant correlation with the presence of TMDs (P = 0.000). There was a significant relationship between Class II malocclusion and TMDs as well as between Class III malocclusion and TMDs. The most common oral habit was placing a pencil or other objects between the teeth. No significant relationships were observed between the prevalence of TMDs and the sex and age groups. This study showed significant relationships between TMDs and anxiety, malocclusion, and parafunctional habits.

Does the Serum Expression Level of High-Mobility Group Box 1 (HMGB1) in Multiple Sclerosis Patients have a Relationship with Physical and Psychological Status? A 12-Month Follow-Up Study on Newly Diagnosed MS Patients.

Background: There is a strong need to identify simple and cost-effective biomarkers for multiple sclerosis (MS). Objectives: To evaluate the serum levels of receptor for advanced glycation end products (RAGE) ligand, the high-mobility group box (HMGB) 1 and its correlation with changes in the physical and psychological indicators in MS patients. Methods: During the 12-month follow-up, the serum level of HMGB1, expanded disability status scale (EDSS) score, rate of clinical relapse, quality of life, and other psychological indicators were assessed at baseline, after 6 months, and after 12 months and compared between 60 newly diagnosed MS patients with 60 healthy controls (HCs). Data were analyzed using t-test and Mann-Whitney U test, two-way repeated measures analysis of variance (ANOVA) and Spearman's rank correlation coefficient. Results: A significant decrease was observed in the EDSS score (P < 0.001) and a significant increase in the serum level of HMGB1 in all MS patients (P = 0.009). The serum level of HMGB1 was higher in MS patients, compared with HCs (baseline: 65.8%, P = 0.007; six-month follow-up: 73.9%, P = 0.004; and 12-month follow-up: 77.6%, P = 0.021). There were significant positive correlations between the serum level of HMGB1 and scores of MS impact scale-psychological subscale (MSIS-PS) (r = 0.59, P < 0.001), Beck depression inventory (BDI) (r = 0.491, P = 0.031), and Pittsburgh sleep quality index (PSQI) (r = 0.471, P = 0.035). Conclusion: The serum level of HMGB1 could predict the patients' psychiatric status better than their physical status.

Smear grading at initial treatment association with treatment outcomes among new smear positive pulmonary tuberculosis patients: A retrospective study.

Introduction: Tuberculosis (TB) is one of the most challenging diseases in diagnosis, treatment and control. We aimed to assess the association of the initial grading of Mycobacterium Sputum Smear (MSS) on the outcomes of TB treatment. Materials and methods: In a retrospective study, data of 418 positive pulmonary smear patients were retrieved from the TB registration system in Iran during 2014 to 2021. Patients' data included demographic, laboratory and clinical information and were recorded in our checklist. The grading of Mycobacterium Sputum Smear (MSS) at the initial treatment was assessed based on World Health Organization (WHO) guidelines. Chi-square test was used to assess the relationship between tuberculosis treatment outcomes and Mycobacterium grade at initial treatment in SPSS. Results: The mean age of cases was 51.19 ± 22.29 years old and varied between 14 and 95 years. Laboratory results showed that the rate of 1-9, 1+,2+ and 3+ Mycobacterium tuberculosis was 17.7%, 44.3%, 19.4% and 18.7%, respectively. The rate of cure, death and treatment failure in patients was 87.1%, 6.9%, and 1.2%, respectively. The highest mortality rate (11.5%) occurred in patients with 3+ and the lower rate of cure was 79.5% in this group. Moreover, by increasing the Mycobacterium grade the rate of transferred out and lost to follow up from treatment increased (p = 0.024). Conclusion: High smear grading of sputum is inversely associated with lower curing and on-time treatment. Moreover, by increasing the Mycobacterium grade at initial treatment, treatment failure and lost to follow up increased Therefore, improvement the health system and patient-diagnosis and screening programs is necessary to on-time diagnosis and facilitate the treatment process.

Efficacy of Common Bile Duct Stenting on the Reduction in Gallstone Migration and Symptoms Recurrence in Patients with Biliary Pancreatitis Who Were Candidates for Delayed Cholecystectomy.

BACKGROUND: In patients with severe biliary pancreatitis, delayed cholecystectomy associated with a high risk of recurrence is recommended. The current study aimed to evaluate the effect of common bile duct (CBD) stenting on reducing gallstones migration and recurrence of symptoms in patients with pancreatitis and delayed cholecystectomy candidates. METHODS: To this purpose, the randomized, controlled clinical trial was performed on 40 patients with biliary pancreatitis who were candidates for delayed cholecystectomy. Patients were randomly divided into two groups of A and B that underwent CBD stenting after ERCP and received endoscopic treatment without stenting, respectively. A checklist recorded demographics and complications. Group A was followed up after four weeks to remove the stent and record the complications. Group B underwent MRCP to examine the migration of new gallstones as well as the complications. RESULTS: Of the 40 patients, 20 subjects (11 males and 9 females) were allocated to each group, matched for demographic variables. In the one-month follow-up, only one subject in group A manifested symptoms of gallstone migration and recurrence, while in group B, recurrence was observed in 6 patients (P = 0.037). There was no significant difference in the success rate of ERCP and the incidence of complications between the two groups. CONCLUSION: CBD stenting in patients with biliary pancreatitis and gallstone could reduce the risk of recurrence and remigration of gallstones in delayed cholecystectomy cases.

Effects of Iranian Polyherbal Syrup (Zufa syrup) on oxygen saturation and clinical symptoms in suspected patients with COVID-19: a triple-blinded, randomized, placebo-controlled trial.

Coronavirus disease 2019 (COVID-19) pandemic has caused an urgent need for investigating potential treatments. Traditional medicine offers many potential remedies that have been historically used and have the advantage of bypassing the cultural obstacles in the practice of medicine. We aimed to investigate the efficacy of Zufa syrup in the treatment of suspected patients with mild to moderate symptoms of COVID-19. This triple-blind randomized controlled trial recruited patients with evidence of COVID-19 on chest computed tomography without an indication of hospital admission from March 2020 until April 2020. Participants were assessed by a physician and completed a pre-specified form to assess the duration and severity of symptoms. Patients were randomized to receive Zufa syrup (a combination of herbal medicines: Nepetabracteata, Ziziphus jujube, Glycyrrhizaglabra, Ficuscarica, Cordia myxa, Papaver somniferum, Fennel, Adiantumcapillus-veneris, Viola, Viper's-buglosses, Lavender, Iris, and sugar) or identical-looking placebo syrup at a dose of 7.5 mL (one tablespoon) every 4 hours for 10 days. After applying the eligibility criteria, 116 patients (49.1% male) were randomized to trial arms with a mean age of 44.3. During the follow-up, Cough, dyspnea, headache, myalgia, anorexia, anxiety, and insomnia improved gradually in both groups, and showed no difference between Zufa syrup and placebo. Oxygen saturation and pulse rate had stable trends throughout the follow-up and were similar between study arms. No patient required hospital admission or supplemental oxygen therapy during the study period. To conclude, in patients with mild to moderate symptoms of COVID-19, Zufa syrup did not show any difference in symptomatology over a 10 days' period when compared with placebo. Due to potential effects of medicinal plants in the treatment of respiratory infections, further studies are warranted to clarify their role in COVID-19. The study was approved by the Ethics Committee of the Qom University of Medical Science (Ethics committee reference number IR.MUQ.REC.1398.165) on March 10, 2020 and was registered in Iranian Clinical Trial Center (approval ID: IRCT20200404046934N1) on April 13, 2020.

CIRCULATING GHRELIN LEVELS AND SUSCEPTIBILITY TO COLORECTAL CÂNCER.

BACKGROUND AND OBJECTIVE: Considering the association between colorectal cancer (CRC) and both insulin resistance and obesity, and the prominent role of ghrelin in these metabolic disorders, we explored whether plasma levels of ghrelin were associated with CRC. Moreover, in the patients with CRC the possible correlations between ghrelin and insulin, insulin resistance, and body mass index (BMI) as an indicator of obesity were examined. METHODS: A total of 170 subjects, including 82 cases with CRC and 88 controls were enrolled in this study. Plasma levels of ghrelin, insulin, and glucose were measured in all the subjects using ELISA and glucose oxidase methods. Furthermore, insulin resistance was assessed by calculating HOMA-IR index. RESULTS: The cases with CRC had decreased ghrelin levels (P<0.001) and a higher HOMA-IR index (P<0.001) than controls. Interestingly, when CRC patients were stratified based on tumor site, lower ghrelin levels and a higher HOMA-IR index were observed in the patients with either colon or rectal cancer vs. controls too. Additionally, there were an age and BMI-independent negative correlation between ghrelin levels and HOMA-IR (r=-0.365, P<0.05), and an age-independent negative correlation between ghrelin levels and BMI (r=-0.335, P<0.05) in the rectal subgroup. CONCLUSION: Our findings support a role for ghrelin in connection with insulin resistance and obesity in CRC susceptibility; however, it needs to be corroborated by further studies.

RESUMO CONTEXTO E OBJETIVO: Considerando a associação entre câncer colorretal (CCR), a resistência à insulina, à obesidade e o papel proeminente da grelina nessas doenças metabólicas, foi explorado se os níveis plasmáticos de grelina estavam associados ao CCR. Além disso, nos pacientes com CCR foram pesquisadas as possíveis correlações entre a grelina, insulina, resistência insulínica e índice de massa corporal (IMC) como indicadores de obesidade. MÉTODOS: Foram incluídos neste estudo 170 indivíduos, sendo 82 com CRC e 88 controles. Os níveis plasmáticos de grelina, insulina e glicose foram medidos em todos os sujeitos utilizando métodos ELISA e glicose oxidase. Além disso, a resistência à insulina foi avaliada pelo cálculo do índice HOMA-IR. RESULTADOS: Os pacientes com CRC apresentaram redução dos níveis de grelina (P<0,001) e maior índice HOMA-IR (P<0.001) do que os controles. Curiosamente, quando os pacientes com CRC foram estratificados com base no local do tumor, níveis mais baixos de grelina e maior índice de HOMA-IR foram observados nos indivíduos com câncer de cólon ou retal versus controles também. Além disso, houve uma correlação negativa entre idade e IMC independente entre os níveis de grelina e HOMA-IR (r=-0,365, P<0,05) e uma correlação negativa independente da idade entre os níveis de grelina e IMC (r=-0,335, P<0,05) no subgrupo retal. CONCLUSÃO: Nossos achados apoiam o papel da grelina em relação à resistência à insulina e à obesidade na suscetibilidade do CRC; no entanto, ela precisa ser corroborada por estudos posteriores.

The effect of peer group education on anxiety, stress, and depression in older adults living in nursing homes.

BACKGROUND: The effects of peer education have been addressed in different populations, but this method of education has not been applied in the elderly population of Iran, and its effect has not been studied. The present study investigated the effects of peer group education on anxiety, stress, and depression of the older adults living in nursing homes. MATERIALS AND METHODS: This research is a quasi-experimental study with an intervention and control group and it was conducted on 70 elderly citizens living in Qom nursing homes in July 2017. For the intervention group, a relaxation and stress reduction program was trained through the peer group. The control group received routine care. Data were collected using a Demographic information questionnaire and Depression Anxiety Stress Scale-21 (DASS-21). Data were collected at the beginning, 10 and 30 days after the intervention. Data analysis was performed using SPSS 19, descriptive statistics, and repeated measure analysis of variance. RESULTS: The results of the study showed no significant difference between any of the demographic variables at the beginning of the study (p > 0.05). The statistical test showed that the effects of time (p < 0.001) and group (p < 0.011) were significant on anxiety, stress, and depression. CONCLUSIONS: The results of this study showed that peer education could decrease anxiety, stress, and depression in the elderly. Therefore, this educational method can be used by nurses to promote various health education programs, e.g., to health promotion and prevent disease especially in the elderly community.

Sexual and Reproductive Health Challenges in Temporary Marriage: A Systematic Review.

BACKGROUND: Temporary marriage is a legal form of marriage in Shia Islam allowing a man and a woman to become married in a fixed period of time. This review was conducted to identify the potential effects of temporary marriage on the sexual and reproductive health of women. STUDY DESIGN: A systematic review . METHODS: Electronic databases, including Web of Knowledge, Embase, PubMed, Scopus, ScienceDirect, PsycINFO, ProQuest, IranMedex, Scientific Information Database (SID), and Magiran, were searched up to October 2020 to identify the studies carried out on sexual and reproductive health challenges in temporary marriage. All the selected articles were assessed for eligibility according to their titles and abstracts. RESULTS: During the search on articles published within 1995 to October 2020, 1,802 relevant records were identified, and after evaluation 30 full-text papers were included in the present systematic review. Out of the 34,085 study participants in the selected studies, 3,547 subjects had temporary marriage who were studied under six different categories, namely (1) sexually transmitted infections (STIs)/human immunodeficiency viruses, (2) early child marriage, (3) unplanned pregnancy and induced abortion, (4) violence, (5) psychosocial disorders, and (6) other issues. Individuals with temporary marriage are vulnerable and need to have easy access to health education and sexual and reproductive health services in a safe and unprejudiced environment. Ignoring the aforementioned facts will cause serious public health problems, especially for women from a lower socioeconomic background. CONCLUSION: In the current situation with under-reporting of temporary marriage-related events due to social stigma and absence of quality services in sexual and reproductive health, women with temporary marriage are under the additional risk of STIs, unwanted pregnancy, abortion, and violence.

Awareness and Performance towards Proper Use of Disinfectants to Prevent COVID-19: The Case of Iran.

This study aimed to assess the awareness and performance of Qom citizens towards using disinfectants and compared its relationship with geographical distribution of COVID-19 outbreak in Qom, Iran. The study was conducted by a researcher-made questionnaire during April and May, 2020. COVID-19 incidence data for each district of city was obtained from health department of Qom province. Data were analyzed using Excel, SPSS and ArcView (GIS) softwares. It was found that the highest level of citizens' awareness (52%) was in the weak range while their performance (56%) was in the good range. According to Spearman's correlation analysis, there was a strong correlation (rho 0.95) between the total mean of awareness and performance (p < 0.01). The highest incidence rate of COVID-19 was in district 7 which had the lowest mean score in both awareness and performance. In addition, the results of ANOVA (LSD-least significant difference) showed that there was a significant difference (p < 0.05) between district 7-with lower mean scores in awareness and performance-and other districts. Overall, it is concluded that citizens' awareness level was lower than that of their performance. This conclusion not only calls for more training programs to be implemented in public places, schools, universities and governmental offices, but it also necessitates maintaining a proper and timely training about using disinfectants.

The effect of dexmedetomidine on decrease of cough, hemodynamic parameters and Ramsay score versus lidocaine during general anesthesia: a randomized clinical trial.

Physiological responses remain common during anesthesia emergence and endotracheal extubation, causing some complications. We aimed to address the effect of dexmedetomidine (DEX) on decrease of cough, hemodynamic parameters and Ramsay score in comparing to lidocaine (LID) during anesthesia. In this double-blinded randomized clinical trial 120 hospitalized patients undergoing general anesthesia were enrolled after obtaining written consent. Block random allocation was used to assign patients into three groups including DEX (intravenous injection; 0.5 µg/kg), LID (1.5 mg/kg), and PBO (10 mL normal saline) at 10 minutes before anesthesia. No statistical significance was uncovered among three groups in blood pressure, oxygen saturation, frequency of laryngospasm and duration of surgery amongst the groups (P > 0.05), but DEX having lower heart rate and cough frequency (P < 0.05). Moreover, the mean of Ramsay score was statistically higher in DEX and LID groups than PBO except at the 50th and 60th minutes after extubation (P < 0.05). Since the mean of Ramsay score was higher in DEX vs. LID groups and reduced heart rate and cough frequency demonstrates in DEX, it seems that DEX could be an appropriate drug on suppressing cough during anesthesia without side effects.

Epidemiological features of brucellosis and factors affecting its treatment failure and relapse in Qom Province, Iran.

Background: Brucellosis is one of the major health problems in many areas of the world, especially in the Mediterranean and the Middle East regions. Objective: To determine the epidemiological characteristics, clinical signs, and risk factors of relapse rate in patients with brucellosis, Qom Province, Iran. Methods: A descriptive-analytic study was conducted on 410 confirmed brucellosis cases in Qom Province, central Iran, from 2015 to 2019, based on epidemiological checklists and according to the Iran Ministry of Health and Medical Education (MOHME). Univariate and multiple logistic regression analyses were conducted using Stata software version 14. Results: The relapse rate of brucellosis was 6.6% until nine months after starting the treatment, and all recurrent cases were infected by Brucella melitensis. Based on univariate logistic regression analysis, the delayed treatment and type species of Brucella were significant factors affecting the relapse of brucellosis. The relapse rates were 5.4%, 6.2%, and 20.0% in patients whose delayed treatments were <50, 51-150, and >151days, respectively. Based on the multiple logistic regression, it was observed that delayed treatment >50 days increased the rate of relapse more than four times. Conclusion: The delayed initiation of treatment was a significant factor influencing the relapse of brucellosis; therefore, it is necessary to provide enough diagnostic and laboratory facilities, and people need to be educated about the signs and symptoms of the disease.
