Introduction: Preventive self-care behaviors such as home quarantine are very important in preventing COVID-19. The aim of this study was to explore the factors of non-compliance with home quarantine during the outbreak of COVID-19. Methods: This study was conducted with a qualitative content analysis approach in 2020 in Iran. In order to collect information, 24 samples were selected by purposive sampling method and semi-structured interviews were conducted with them. Interviews were recorded, transcribed and the collected data were analyzed using the contractual content analysis approach using Elo and Kingas method. Results: Analyzing the data revealed in six main themes and fourteen main categories, including: necessities for everyday activities and living (with subthemes providing the necessities of life, forced by work/job insecurity, need for fun/entertainment, sports), mental instability in adults/children (with subthemes of mental states, restlessness of children), spiritual and religious beliefs (with subthemes of belief in fate and immunity/disease immunity, right to know death), managerial problems/confusion (with subthemes of government mismanagement, expectations from the government, economic turmoil), marital incompatibility (with subthemes domestic violence), adherence to socio-cultural patterns (with the subthemes of sociocultural factors). Conclusion: According to the results, it should be noted that several factors are contributing to non-compliance with home quarantine that it is necessary for the relevant authorities to take measures to remove these obstacles and provide the necessary facilities.

Background: Infection with hepatitis C virus (HCV) is increasingly recognized as a major global health problem. Objectives: The aim of this study was to measure the prevalence of HCV infection and determine the risk factors associated with HCV among male people who inject drugs (PWID) in Kermanshah, Iran. Methods: In this cross sectional study, the samples were recruited from 2 drop-in centers and related community outreach sites, using snowball sampling. The questionnaire consisted of 3 sections, including demographics, drug use patterns, and risky behaviors. HCV infection was tested in venous blood samples, collected from the participants, using the ABON rapid test kit. Logistic regression analysis was used to determine the association between HCV status and the associated factors, reported as odds ratio (OR) and 95% confidence interval (CI). Results: The mean age of the participants was 36.7 ± 8.5 years (range, 18 - 65 years). Over half of the participants (54.8%) tested positive for HCV antibodies; in other words, they had been exposed to the virus. Adjusted OR for people reporting shared equipments within the past month was 3.36 times higher than the OR of people who reported no shared equipments (P = 0.000). The adjusted OR of positive HCV among those who injected twice or more per day was 4.33 (P = 0.000), compared to those who injected only once a day (or less). With over half the participants having evidence of HCV exposure, there is a need to increase the coverage of harmreduction programs, especially sterile injection equipment programs. Moreover, increasing access to harm-reduction programs and HCV treatment can ultimately reduce the opportunities for HCV transmission.

Introduction: Communication skills are a set of behaviours through which aperson communicate with others in such a way leading to positive responses and the avoidance of negative responses. This study aims to predict the determinants of interpersonal communication skills among healthcare providers of Ahvaz city based on the extended theory of reasoned action. Methods: This cross-sectional descriptive study was condcuted on 160 healthcare providers of Ahvaz city in 2021using random sampling. Data collection tool was a researcher-made questionnaire. The data were analyzed by SPSS version 24 and AMOSS version 22 software, using correlation tests, regression analysis, independent samples t-test and paired t-test. Results: The mean age and work experience of the participants was 35.76± 6.55 and 10.31± 6.79 years, respectively. The results of Pearson correlation indicated a direct and significant correlation between attitude (r = 0.527), subjective norm (r = 0.243), and self-efficacy (r = 0.630) together and with behavioral intention. Among the constructs of the extended theory of reasoned action, self-efficacy (r = 0.630) and subjective norm (r = 0.243) had the highest and lowest correlation with behavioral intention of health care providers, respectively. Furthermore, this theory predicted 0.22 variance of attitude, 0.02 variance of subjective norm and 0.49 variance of self-efficacy. Self-efficacy was the strongest and subjective norms was the weakestpredictors of communications skills behavior, respectively. Conclusion: According to the results, it seems that in planning to implement behavioural interventions to promote interpersonal communication skills in healthcare providers, more emphasis should be placed on strategies related to increasing attitude, self-efficacy, and behavioural intention.

One of the main factors that causes health effects in humans such as hospital admissions for cardiovascular disease (HACVD), respiratory disease (RD), lung function, cardiovascular mortality (MCVD), lung cancer, and increased mortality is air pollution especially particulate matter (PM). This a systematic review and meta-analysis aims to investigate the effects of particulate matter on the occurrence of cardiovascular disease and mortality. A systematic review and meta-analysis of the literature was done from 2011 to 2021 based on various databases. Based on the result of this study, subgroup analysis based on temperature conditions showed a different estimation in cold cities (6.24, UR (4.36–8.12)), moderate cities (4.86, UR (3.57–6.15)) and warm cities (8.96, UR (7.06–10.86)). Test of group differences showed a significant difference (Q=12.22, p-value

Eye care is one of the most critical tasks of intensive care unit (ICU) nurses. Patients in this unit are exposed to potential ocular problems due to critical conditions. This study aimed to establish a new eye care protocol for preventing ocular surface disorders in patients admitted to ICU. This was a clinical trial study performed on patients admitted to ICU in 2019. The data gathering tools included the demographic questionnaire, the Schirmer test for dry eye, fluorescein staining and slit lamp manual for examining corneal ulcers, and slit lamp manual to check keratitis and conjunctivitis. A type of eye care protocol was performed on the patient's eyes. After five consecutive days of executing the protocol, the data were analyzed using SPSS software version 18. The use of eye care protocol reduced the risk of keratitis (P=0.027), conjunctivitis (P=0.012), eye dryness (P=0.001), and corneal ulcer (P=0.003) in patients admitted to ICU in the intervention group compared to the control group. Ophthalmology protocols reduced the incidence of keratitis, conjunctivitis, dry eye, and corneal ulcers in ICU patients. Therefore, using this method in ICU patients can improve nursing care.

Background and aims: Injection drug use is considered as an international public health threat that can lead to serious health-related outcomes. The aim of this study was to obtain a profile of injection drug users (IDUs) in Kermanshah, Iran, in 2017. Methods: This cross-sectional study was carried out on 606 male IDUs who were recruited from 2 drop-in centers in Kermanshah using a snowball sampling method. Continuous and categorical variables are expressed as the mean and standard deviation, as well as frequency and percentage, respectively. Results: The mean age of participants in this study was 36.7±8.51 years and at first drug injection was 29.35±8.04 years. In addition, the highest frequency of injection drugs belonged to heroin (99.00%), methamphetamine (86.00%), and opium (85.00%), respectively. However, the lowest injection drugs were opium syrup (0.50%), ecstasy (0.50%), and amphorphine (0.20%). Conclusion: Based on the findings of this study, heroin, methamphetamine, and opium had the highest frequency injection among male IDUs in Kermanshah, and the age of the first drug injection was low among these individuals. Accordingly, wider coverage prevention programs are highly recommended, including harm reduction programs, counseling centers with improved quality of services, treatment programs, and greater attention to human resource development-based counseling and education.

Background Managing the amount of use of sedatives due to their high side effects in the intensive care unit is essential. Sedation-agitation protocols may play an important role in this regard. However, they have not been practically applied in Iran. Aims This study aimed to evaluate the effect of using the Richmond agitation and sedation scale on hospital stay duration and dependency rate on the intensive care unit ventilator system in Ahwaz City, Iran, in 2016–2017. Methods This randomised clinical trial was conducted on 74 patients. The subjects were selected by a stratified sampling method and divided into the experimental ( n = 32) and control ( n = 32) groups. Sedation and agitation levels were managed by the Richmond agitation and sedation scale as soon as the samples were anxious and agitated, and every 6 hours in the intervention group. However, the control group received routine care. The data obtained were analysed by the Statistical Package for the Social Sciences (SPSS). Results There was no significant difference between the two groups in terms of demographic variables, such as age, gender, admission diagnosis and Glasgow coma scale scores on admission. However, they differed in terms of hospital stay duration and ventilator connection ( P Conclusions Based on the results of this study, as well as the approval of validation and reliability of the Richmond agitation and sedation scale in different studies, this protocol can be very effective in optimising the use of sedatives in the intensive care unit.

Background Non-alcoholic fatty liver disease (NAFLD) is a prevalent chronic liver diseases. The aim of this study was to evaluate the effect of combined weight loss diet and cranberry supplementation on inflammatory, antioxidant and apoptosis biomarkers in patients with NAFLD. Methods In this randomized, double-blinded, controlled clinical trial, 41 NAFLD patients were supplemented with either a 288-mg cranberry tablet or a placebo tablet for 12 weeks. Both groups followed a diet of 500–1000 calories less than the estimated energy requirements. Serum levels of Total antioxidant capacity (TAC), Malondialdehyde (MDA), Cytokeratin 18-M30 (CK-18 M30), Chemokine C-C motif ligand 2 (CCL2) and Tumour necrosis factor alpha (TNF-α) were measured at both baseline and the end of the study. Results Significant improvements in TAC were observed in the cranberry group and between the two groups (p = 0.006 and p = 0.011 respectively), but the changes in the placebo group were not significant (p = 0.325). There were no statistically significant differences in the serum levels of MDA, CK-18 M30, CCL2 and TNF-α between the cranberry and the placebo groups (p > 0.05). Conclusions It seems that daily consumption of cranberry supplement would be beneficial in increasing serum levels of TAC. Further studies are needed to investigate the effects of anti-inflammatory and antioxidant properties of cranberry on NAFLD.

Background: Urinary tract infection is one of the most common bacterial infections in children. Zinc is the second most abundant mineral in the body involved in the growth, cell division, and regulation of immune system activity. In studies, zinc administration has been effective in improving pneumonia and gastroenteritis in children, and today, zinc is used to treat acute gastroenteritis in children. Due to the increasing use of various supplements in children and the importance of urinary tract infection and its complications in children. Objectives: This study was performed to compare serum zinc levels between children with febrile urinary tract infection and healthy children. Methods: In this case-control study, serum zinc was measured in 60 healthy children and 60 children with febrile urinary tract infection, without any underlying disease, by an Auto analyzer. Data were analyzed by SPSS version 22 software. Results: The difference in serum zinc levels between the two groups was not statistically significant. There was no statistically significant difference in zinc deficiency between the groups. Serum zinc levels were not associated with sex, age, frequency of urinary tract infection, the severity of leukocytosis, the severity of ESR increase, CRP, and length of hospitalization. In the age group of 24 - 72 months, a significant linear relationship was observed between serum zinc levels and weight. The incidence of urinary tract infections was higher in girls, and this difference was statistically significant in all groups, except in age groups 6 - 12 months and above 72 months. Conclusions: This study showed that low serum zinc levels did not increase the risk of febrile urinary tract infection in children. Therefore, prescribing zinc supplements to treat or prevent urinary tract infections requires further studies.

Background: Blood exchange transfusion (ECT) therapy is an essential part of the modern health care for high-risk icteric neonates. Objectives: Therefore, this study sought to examine the effectiveness of monitoring sodium disorders and the required interventions indicating the overall state of health of hospitalized jaundiced neonates. Methods: This prospective analytic study was performed on 49 neonates diagnosed with severe jaundice undergoing screened exchange blood transfusion from November 2018 to May 2019. Serum sodium ion concentrations testing was performed before the exchange, then 1 - 3 hours later, and again 24 hours after receiving ECT, using a sensitive ELISA kit in a laboratory. Using the newest version of SPSS 24 software program, the association between different numerical variables was calculated by a repeated-measure ANOVA test. P < 0.05 criterion was set as the threshold of significance. Results: Out of the total 49 neonates, 24 (48.5%) were girls and 25 (51.5%) were boys, of which 93.9% and 6.1% were term and preterm-born neonates, respectively. The average birth weight was 2843 ± 267/510 g and the mean period of hospital stay was 4.55 ± 2.399 days. The various causes of severe neonatal jaundice of all the hospitalized cases were 45% unknown, 43% combined ABO and Rh incompatibility, 10% breastfeeding pattern, and 2% G6PD deficiency. A continual fall in serum sodium was observed following banked blood exchange (P < 0.05). However, these reversible changes were outside the expected normal range. Despite a diminished sodium concentration, the mean sodium levels were within the laboratory reference range of serum (137 - 142 mEq/L) in all the three measured duration times. Moreover, variation in the amount of serum sodium was associated with an unknown underlying cause that led to neonatal jaundice (P = 0.04) and this difference did not reach statistical significance in terms of birth weight, gestational age, and other causes accounting for high bilirubin (P > 0.05). Conclusions: Given these facts, it was concluded that neonatal jaundice was significantly associated with post-exchange serum sodium changes within the laboratory reference range of serum.

Objective: Although comorbidity of psychotic disorders and substance use can lead to increase in mortality, less is known about the outbreak and predictors. Psychotic patients tend to be overlooked during assessment; hence, the possibility of an undertreated or missed condition such as increasing substance use. This investigation aimed to measure the prevalence of substance use in psychotic patients and to survey the powerful predictors. Method: In a 1-year cross-sectional study, 311 psychotic patients were assessed using the Structured Interview Based on DSM-5 for diagnostic confirmation as well as questions surveying prevalence and possible predictors of substance use. Results: Prevalence of substance use among psychotic patients was 37.9%. Several variables were identified as factors associated with drug abuse among the psychotic patients. These included male gender, younger age, being currently homeless, a history of imprisonment, and having family history of drug use. The strongest predictors of substance use, however, were family history of drug use, male gender, and being currently homelessness. Conclusion: Policymakers should note the importance of substance use among psychotic patients. Developing active screening strategies and comprehensive preventive plans, especially in the high-risk population, is suggested.

Background Although comorbidity of substance use and psychotic disorders can lead to increase in morbidity and mortality, less is known about the prevalence and predictors. Patients with psychosis tend to be overlooked during clinical assessment, therefore, the possibility of a missed or undertreated condition such as substance use increases. This study aims to measure the prevalence of substance use in patients with psychosis and to assess the strongest predictors.Method In a 1 year observational study (October 2017- November 2018), 311 patients with psychosis who were admitted to Razi Psychiatry Hospital; Tehran; Iran were surveyed through The Structured Interview Based on DSM-5 (SCID) for diagnostic confirmation as well as questions assessing prevalence and possible predictors of substance use.Results Prevalence of Substance Use among Psychiatric Patients with Psychosis was 37.9%. In bivariate analysis, several variables were identified as factors correlated with drug abuse among the participants. These included younger age, male gender, being currently homeless, having family history of drug use, and a history of imprisonment. The most powerful predictor of substance use, however, were male gender, Family history of drug use and being currently homelessness.Conclusion The prevalence of substance use was high among all psychotic disorders, therefore, it is suggested that professionals note the importance of substance use among psychotic patients. The most powerful predictors were male gender, history of imprisonment, and family history of drug use. Active investigation and comprehensive preventive plans are suggested in all patients with psychosis especially among high risk population.

In this study, the therapeutic efficacy of quercetin in combination with remdesivir and favipiravir, were evaluated in severe hospitalized COVID-19 patients. Our main objective was to assess the ability of quercetin for preventing the progression of the disease into critical phase, and reducing the levels of inflammatory markers related to SARS-Cov-2 pathogenesis. Through an open-label clinical trial, 60 severe cases were randomly divided into control and intervention groups. During a 7-day period, patients in the control group received antivirals, i.e., remdesivir or favipiravir, while the intervention group was treated with 1000 mg of quercetin daily in addition to the antiviral drugs. According to the results, taking quercetin was significantly associated with partial earlier discharge and reduced serum levels of ALP, q-CRP, and LDH in the intervention group. Furthermore, although the values were in normal range, the statistical outputs showed significant increase in hemoglobin level and respiratory rate in patients who were taking quercetin. Based on our observations, quercetin is safe and effective in lowering the serum levels of ALP, q-CRP, and LDH as critical markers involved in COVID-19 severity. However, according to the non-significant borderline results in comparing the mortality, the ICU-admission rate, and the duration of ICU-admission, further studies can be helpful to compensate the limitations of our study and clarify the therapeutic potential of quercetin in COVID-19 treatments.

Background: The basic reproduction number (R 0 ) is an important concept in infectious disease epidemiology and the most important parameter to determine the transmissibility of a pathogen. This study aimed to estimate the nine-month trend of time-varying R of COVID-19 epidemic using the serial interval (SI) and Markov Chain Monte Carlo in Lorestan, west of Iran. Study design: Descriptive study. Methods: This study was conducted based on a cross-sectional method. The SI distribution was extracted from data and log-normal, Weibull, and Gamma models were fitted. The estimation of time-varying R 0 , a likelihood-based model was applied, which uses pairs of cases to estimate relative likelihood. Results: In this study, R t was estimated for SI 7-day and 14-day time-lapses from 27 February-14 November 2020. To check the robustness of the R 0 estimations, sensitivity analysis was performed using different SI distributions to estimate the reproduction number in 7-day and 14-day time-lapses. The R 0 ranged from 0.56 to 4.97 and 0.76 to 2.47 for 7-day and 14-day time-lapses. The doubling time was estimated to be 75.51 days (95% CI: 70.41, 81.41). Conclusions: Low R 0 of COVID-19 in some periods in Lorestan, west of Iran, could be an indication of preventive interventions, namely quarantine and isolation. To control the spread of the disease, the reproduction number should be reduced by decreasing the transmission and contact rates and shortening the infectious period.

Understanding and increasing awareness on individual risk for HIV infection as well as HIV risk perception’s effects on different behavioral outcomes for people who inject drugs (PWID) is important for policymaking and planning purposes. The objectives of the present study were to determine whether HIV risk perception was associated with greater injection and sexual risk-taking behaviors among PWIDs. We surveyed 460 PWID in Kermanshah regarding their demographic characteristics, sexual risk behaviors, HIV risk perception, and drug-related risk behaviors in the month prior to the study. Three classes of HIV risk perception were identified using ordinal regression to determine factors associated with HIV risk perception. Study participants were categorized as follows: “low” (n = 100, 22%), “moderate” (n = 150, 32%), and “high” (n = 210, 46%) risk perception for becoming infected with HIV. The odds of categorizing as “high” risk for HIV was significantly greater in PWID that reported unprotected sex (adjusted odds ratio (AOR) 2.4, p value 0.02), receptive syringe sharing (AOR 1.8, p value 0.01), and multiple sex partners (AOR 1.4, p value 0.03). PWID who reported unprotected sex had 2.7 times the odds of “high” risk perception when compared to PWID with “low” risk perception. Findings show that PWID could rate their HIV risk with acceptable accuracy. Additionally, perceived HIV risk was associated with many risk factors for transmission of HIV, emphasizing the importance of developing targeted prevention and harm reduction programs for all domains of risk behaviors, both sexual and drug-related use.

Introduction: Due to the complexity of the situation and rapid changes in patients' clinical status in intensive care units, it is necessary to teach decision-making skills to nurses, alongside critical thinking. The aim of this study was to evaluate critical thinking training by using critical thinking cards on clinical decision-making of nurses in cardiac care units (CCU). Methods: In this quasi-experimental study, 74 CCU nurses from the selected hospitals affiliated to Ahvaz and Dezful Universities of Medical Sciences were selected based on the inclusion criteria and were assigned to either the intervention or the control group by using permuted block randomization. The data were entered into SPSS V22 and analyzed. Results: There was no statistically significant difference between the demographic characteristics of the two groups (P < 0.05). The mean total score of nurses' clinical decision-making before training sessions in the intervention group was calculated to be 141.59 ± 10.76, which was lower compared to a score of 148.56 ± 10.95 in the control group (P = 0.011). Therefore, covariance analysis was used to modify the results. The mean total score of nurses' clinical decision-making after the training in the intervention group was calculated as 163.82 ± 8.83, indicating a significant increase compared to a score of 154.50 ± 11.25 in the control group (P < 0.001). Conclusion: The findings of the present study show that the education of critical thinking by using the critical card tool leads to improved clinical decision-making in CCU nurses.

In this study, the influence of the applied magnetic field is investigated for magneto-micropolar fluid flow through an inclined channel of parallel porous plates with constant pressure gradient. The lower plate is maintained at constant temperature and the upper plate at a constant heat flux. The governing motion and energy equations are coupled while the effect of the applied magnetic field is taken into account, adding complexity to the already highly correlated set of differential equations. The governing equations are solved numerically by explicit Runge–Kutta. The velocity, microrotation, and temperature results are used to evaluate second law analysis. The effects of characteristic and dominate parameters such as Brinkman number, Hartmann Number, Reynolds number, and micropolar viscosity parameter are discussed on velocity, temperature, microrotation, entropy generation, and Bejan number in different diagrams. The results depicted that the entropy generation number rises with the increase in Brinkman number and decays with the increase in Hartmann Number, Reynolds number, and micropolar viscosity parameter. The application of the magnetic field induces resistive force acting in the opposite direction of the flow, thus causing its deceleration. Moreover, the presence of magnetic field tends to increase the contribution of fluid friction entropy generation to the overall entropy generation; in other words, the irreversibilities caused by heat transfer reduced. Therefore, to minimize entropy, Brinkman number and Hartmann Number need to be controlled.

Background The transition from non-injection to injection drug use dramatically increases the risk of transmitting HIV and other blood borne infections including hepatitis B virus (HBV) and hepatitis C virus (HCV). The aim of this study was to explore factors associated with the transition from first illicit drug use to first injection among drug users. Methods Using snowball sampling and convenience sampling through needle and syringe programmes (NSPs), we recruited 500 people who inject drugs (PWID) in Kermanshah, between September and December 2014. Trained interviewers collected data on socio-demographic characteristics, HIV testing and drug-related risk behaviors over the last month prior to interview using a structured questionnaire. Our main outcome variable was first illicit drug use to first injection (TIJ). TIJ was calculated by subtracting age at first drug injection from age of first illicit drug use. Results Overall, the average age at first drug use and injection were 21.4 [standard deviation (SD 5.6)] and 22.8 (SD 8.9), respectively. The average duration of injection was 6.0 (SD 4.6) years. Overall, the mean of TIJ for participants was 1.4 (IQR = 2, 4) years. Age of first injecting drug use negatively correlated with TIJ (R 2 = 0.219, p = 0.001). Education level and socioeconomic status (SES), and negatively correlated with TIJ. Conclusion Some demographic factors and drug use characteristics including educational level, SES, knowledge of HIV status, age of initiating drug use, being a poly drug user and using methamphetamine were predictors of the time to transition.

In this study, the hydrodynamic characteristics are investigated for magneto-micropolar fluid flow through an inclined channel of parallel plates with constant pressure gradient. The lower plate is maintained at constant temperature and upper plate at a constant heat flux. The governing equations which are continuity, momentum and energy are are solved numerically by Explicit Runge-Kutta. The effect of characteristic parameters is discussed on velocity and microrotation in different diagrams. The nonlinear parameter affected the velocity microrotation diagrams. An increase in the value of Hartmann number slows down the movement of the fluid in the channel. The application of the magnetic field induces resistive force acting in the opposite direction of the flow, thus causing its deceleration. Also the effect of pressure gradient is investigated on velocity and microrotation in different diagrams.

Background: Infection with hepatitis C virus (HCV) is increasingly recognized as a major global health problem. Objectives: The aim of this study was to measure the prevalence of HCV infection and determine the risk factors associated with HCV among male people who inject drugs (PWID) in Kermanshah, Iran. Methods: In this cross sectional study, the samples were recruited from 2 drop-in centers and related community outreach sites, using snowball sampling. The questionnaire consisted of 3 sections, including demographics, drug use patterns, and risky behaviors. HCV infection was tested in venous blood samples, collected from the participants, using the ABON rapid test kit. Logistic regression analysis was used to determine the association between HCV status and the associated factors, reported as odds ratio (OR) and 95% confidence interval (CI). Results: The mean age of the participants was 36.7 ± 8.5 years (range, 18 - 65 years). Over half of the participants (54.8%) tested positive for HCV antibodies; in other words, they had been exposed to the virus. Adjusted OR for people reporting shared equipments within the past month was 3.36 times higher than the OR of people who reported no shared equipments (P = 0.000). The adjusted OR of positive HCV among those who injected twice or more per day was 4.33 (P = 0.000), compared to those who injected only once a day (or less). With over half the participants having evidence of HCV exposure, there is a need to increase the coverage of harm-reduction programs, especially sterile injection equipment programs. Moreover, increasing access to harm-reduction programs and HCV treatment can ultimately reduce the opportunities for HCV transmission.

Burn is the most common pediatric injuries all over the world. The aim of this study was to study the epidemiology of burn in under 15-year-old Iranian children by applying a systematic review. The related articles published before 2016 have been gathered from international databases by using the keywords in term of pediatric burns such as ScienceDirect, PubMed, Iranmedex, Google Scholar, Embase, Magiran, and SID. The checklists of STROBE have been applied to evaluate the quality of the reviewed data. A total of 35 relevant studies were extracted and evaluated. In most studies, the incidence of pediatric burns in male patients was more than female patients by 9.5 to 50 cases in 100,000 per children. Mortality rate of pediatric burn was between 1.7 and 18.5%. The most common cause of pediatric burn was hot water or other hot liquids. Pediatric burn in urban areas was higher and the highest number of pediatric burns occurred at home. Burn is considered as one of the major incidents related to children's health that required planning to reduce its incidence, especially in the lower age groups as well as male patients who are more active and susceptible to burn.

Radiation therapy in breast cancer patients has been shown to reduce local recurrence and improve survival rates. Nevertheless, recent concerns have been raised regarding an increase in cardiac mortality, especially in patients who had been treated with radiation for left-sided breast tumors. Hence, the aim of this study is to estimate doses of irradiation to the heart, LAD coronary artery, and lungs in 2D (SAD) and 3D conformal radio therapy techniques, and to compare the two. Out of 32, 18 to 75 years old females with a diagnosis of non-metastatic breast cancer, who referred from surgery department, went through irradiation in the conventional 2D (SAD) and then 3DCRT using multi-slice CT scans to contour vital organ. Nearly all of the dosimetrical indexes were higher in 3DCRT method. This shows that 2D technique lacks a decent scale to measure cardiac toxicity since its mid-plane CT slice did not give a reliable assessment of cardiac irradiation.
