Background: Cryptosporidium species are coccidian parasites that cause gastrointestinal disorders in humans and other animals worldwide. Objective: The aim of this study was to demonstrate the rate of contamination with Cryptosporidium spp. oocysts in soils collected from public parks, primary schools, green areas, kindergartens, suburban areas, streets, residential complexes, backyards and a passenger terminal in Yazd, central Iran. Materials and Methods: This cross-sectional study was conducted from September 2014 to February 2015, and the samples were collected from 9 different study sites and 56 regions. Soil samples were investigated by flotation technique and modified Ziehl–Neelsen staining for Cryptosporidium spp. oocysts. Finally, the slides were examined with a light microscope. The data were analyzed using SPSS software version 20.0 and chi-square statistical test. Results: Of a total of 220 soil samples, 47 (21.36%) were found to contain Cryptosporidium spp. oocysts. Statistical analysis showed that there was no significant difference between the contamination rate and different study sites in Yazd, central Iran (P>0.05). The highest contamination rate was observed in public parks (38.3%) and the lowest in passenger terminal, kindergartens and streets (4.25%) (P=0.934). Conclusion: The results of the present study show that the contamination of soil with Cryptosporidium spp. can be considered a serious problem in Yazd, central Iran. It should be considered particularly in public parks.

ABSTRACT Introduction Epidemiological data on gingivitis in children are important for understanding the natural course of the disease, identifying its risk factors, and predicting its time trends. The objective of this study was to evaluate the prevalence and severity of gingivitis among 6- and 12-year-old school children in Dhamar city, Yemen. Materials and methods A total of 663 children (310 children of 6 years old and 353 children of 12 years old) were examined from 10 public primary schools. Gingival health status was assessed using the plaque index (PI), calculus index (CI), and gingival index (GI) on the six Ramfjord teeth. The latter index was used to categorize gingivitis severity at the subject level. Data were analyzed using independent t-test, chi-squared test, and Spearman's correlation. A p-value of < 0.05 was considered significant. Results Both age groups had high mean of PI and GI with nonsignificant difference. The 12-year-old children had calculus deposits much higher than the 6-year-old group with significant difference. There was a significant correlation between age and gender of the whole sample with CI [(odds ratio, OR = 1.65, p = 0.003) and (OR = 0.74, p = 0.05) respectively]. Most of the participants presented with gingival inflammation, which was less in 12-year-old females. Conclusion Poor oral hygiene and mild gingivitis were highly prevalent among Yemeni school children. Clinical significance The early assessment and intervention of gingivitis and periodontitis will minimize the chance of tooth loss. It has been reported that marginal gingivitis begins early in childhood, increases in prevalence and severity at puberty, and then subsides slightly to the remainder of the second decade of life.

Objective:The objective of the present study was to find the prevalence of attention deficit hyperactivity (ADH) symptoms in a highly consanguineous community.Design:A cross sectional study was conducted during October 2006 - January 2007.Subjects and methods:A total of 2500 primary school students, aged 6-12 years were randomly selected from the government primary schools and 1869 students (74.8%) gave consent to participate in this study.Results:Of the students surveyed, 50.7% were boys and 49.3% girls. The data revealed that 158 boys [16.7%; 95%CI (14.4-19.2] and 50 girls [5.4%;95%CI (4.1-7.1)] scored above the cut-off (≥15) for ADH symptoms, thus giving an overall prevalence of [11.1%; 95%CI (9.7-12.6)]. The Children who had higher score for ADH symptoms were in the age group 6-9 years. Children who had higher score for ADH symptoms had school performance poorer than those with lower scores (P=0.002). 200 children (96.2%) with ADH were disobedient, 60.6% noisy and hyperactive, 36.5% very cranky, 37.5% troublesome and 37.9% nervous. The logistic regression identified in our study that socio-economic condition, number of children, school performance and poor relationship between parents were the main contributors for ADH. This shows that the consanguinity has no impact on ADH children.Conclusion:The study revealed that ADH symptoms are found to be a common problem among the school children in Qatar. A significant difference was found between children with and without ADHD for their behaviour.

Background: Due to the variations in tooth anatomy and size among different populations, this study aimed to compare the mesiodistal width of primary second molars in Iraqi children with the mesiodistal width of stainless-steel crowns from different companies. Materials and Methods: This cross-sectional study was conducted on 220 intact maxillary and mandibular primary second molars selected from boys and girls’ Iraqi children aged 8-9 years collected from different primary schools in Baghdad city. The mesiodistal dimensions of the selected teeth and the available maxillary and mandibular stainless-steel crowns from three different companies were measured by using a 3-D scanner, and then the whole measurements were calculated using 3 shape Ortho-analyzer software program. Results: Data were analyzed statistically via SPSS V 26 software and the results showed that there’s non-significant difference between the MD measurements of second primary molars between right and left sides, and high significant difference were recorded with higher mean values for boys than girls. When comparing the same mesiodistal measurement between molars with that of stainless-steel crowns, only limited sizes of stainless steel crowns were found to be fitted to the molars of Iraqi children. Conclusion: more studies need to be applied using other stainless steel crown companies to find the relation in the mesiodistal measurement of Iraqi populations.

Objectives: Our objective in this study was to establish the relationships among active and inactive physical activity, HRQoL, and weight stigma in children. Additionally, we investigated weight stigma as a mediator of the relationship between physical activity and HRQoL.Methods: This cross-sectional study was conducted in Hong Kong (June 2017-July 2018). Participants were 437 children in elementary school (2 primary schools and 2 non-governmental organizations) and their parents (dyads). Participants completed questionnaires containing items assessing demographic characteristics, physical activity level, and several HRQoL measures.Results: We found a statistically significant difference between a higher physically activity group (exercise > 2 hours/week) in all measures of HRQoL. Weight stigma had a significant mediating effect on the relationship between physical activity and child-rated HRQoL (Coefficient = -0.37; SE=0.05; t = 8.21; p < .001), parent-rated HRQoL (Coefficient = -0.16; SE = 0.04; t = 4.21; p < .001), and child-rated weight-related QoL (Coefficient = -0.56; SE = 0.04; t = 14.92; p < .001). Conclusions: Physical activity was associated with better HRQoL and lower weight stigma. Weight stigma appears to affect how physical activity is related to better HRQoL, but the association is somewhat weak.

Purpose The aims of this study were to characterize hearing symptoms, habits, and sound pressure levels (SPLs) of personal audio system (PAS) used by young adults; estimate the risk of developing hearing loss and assess whether instructions given to users led to behavioral changes; and propose recommendations for PAS users. Method A cross-sectional study was performed in 50 subjects with normal hearing. Procedures included questionnaire and measurement of PAS SPLs (real ear and manikin) through the users' own headphones and devices while they listened to four songs. After 1 year, 30 subjects answered questions about their usage habits. For the statistical analysis, one-way analysis of variance, Tukey's post hoc test, Lin and Spearman coefficients, the chi-square test, and logistic regression were used. Results Most subjects listened to music every day, usually in noisy environments. Sixty percent of the subjects reported hearing symptoms after using a PAS. Substantial variability in the equivalent music listening level (Leq) was noted ( M = 84.7 dBA; min = 65.1 dBA, max = 97.5 dBA). A significant difference was found only in the 4-kHz band when comparing the real-ear and manikin techniques. Based on the Leq, 38% of the individuals exceeded the maximum daily time allowance. Comparison of the subjects according to the maximum allowed daily exposure time revealed a higher number of hearing complaints from people with greater exposure. After 1 year, 43% of the subjects reduced their usage time, and 70% reduced the volume. A volume not exceeding 80% was recommended, and at this volume, the maximum usage time should be 160 min. Conclusions The habit of listening to music at high intensities on a daily basis seems to cause hearing symptoms, even in individuals with normal hearing. The real-ear and manikin techniques produced similar results. Providing instructions on this topic combined with measuring PAS SPLs may be an appropriate strategy for raising the awareness of people who are at risk.

Background: This study aims to determine and compare the levels of trace elements copper, zinc, selenium and chromium in GCF and serum of patients with periodontitis and healthy individuals. Methods: This cross sectional study includes 24 study subjects recruited from the patients reporting to the Department of Periodontics , Tagore Dental College Chennai. All the selected patients were subjected to a clinical examination done by a single examiner. The estimation of trace elements Copper, Zinc, Selenium and Chromium in GCF and serum is performed using Perkin Elmer optima 5300 Inductively Coupled Plasma Emission Spectrometer (ICPOES). Results: GCF and serum copper levels showed no significant difference in both periodontitis and healthy groups . Selenium levels tend to be the same in both groups. Serum zinc levels are more in periodontitis patients than healthy subjects (p less than 0.01). GCF chromium levels are found to be more in patients with periodontitis than healthy. Conclusions : More research is therefore needed to monitor the role of these trace elements C with an increased sample size to ascertain whether they are associated with a reduced risk of periodontitis.

Background: Postpartum depression with a different incidence of 40- 45% in different societies, which it has adverse effects on the health of mothers and their child, given the negative effects of maternal depression and its harmful effects on the baby and the quality of family life. So, this study was performed with the aim to determine postpartum depression and its associated factors in Bandar Abbas city. Materials and Methods: A descriptive cross-sectional study was conducted in 2015 after obtaining consent from mothers by the census. A total of 343 mothers was examined for depression who referred to Bandar Abbas health centers in the 2nd and 4th months after childbirth. The data collection tools included demographic information and Postpartum Depression Edinburgh questionnaires. Finally, the statistical analyses were performed using SPSS (version 22.0) software and data were analyzed using the Independent t-test, Mann Whitney, Chi-square, and Fisher exact tests.Result: Totally, 68 (19.8%) of samples were in the second month and 54 (15.7%) in the fourth month after delivery had postpartum depression. The incidence of depression in the four months was 6.6%. There was a significant difference between depression and income, parental education, father’s use of cigarette and abnormalities of the infant (P <0.001). There was no significant difference between other factors such as gestational age, infant sex, birth weight, unwanted pregnancy, and type of delivery. Conclusion: Regarding the prevalence of this disorder, it seems that postpartum depression screening planning should be considered during child routine care as an essential component, especially for vulnerable groups.

Background: There has been a rapid rise in cases of COVID-19 infection and its mortality rate since the first case reported in February 2020. This led to the rampant dissemination of misinformation and rumors about the disease among the public. Objectives: To investigate the scale of public misinformation about COVID-19 in Basrah, Iraq. Methods: A cross-sectional study based on a 22-item questionnaire to assess public knowledge and understanding of information related to the COVID-19 infection. Results: A total of 483 individuals completed the questionnaire. The most frequent age group was 26–35 years (28.2%); there were 280 (58%) males and 203 (42%) females. Of the participants, 282 (58.4%) were with an education level below the Bachelor’s degree, 342 (70.8%) were married, and 311 (64%) were living in districts in Basra other than the central district. Overall, 50.8% (11.8/ 22 * 100%) of individuals had the correct information regarding COVID-19. There was a significant association between the level of COVID-19 related misinformation and participants’ educational levels and occupation (p <0.05). However, there was no significant difference found across sex, age group, marital state, and area of residence. Conclusions: Misinformation related to COVID-19 is widely spread and has to be addressed in order to control the pandemic. Keywords: COVID-19, misinformation, knowledge, Iraq

Background: Tamoxifen (TAM) is a frequently used hormonal prodrug for patients with breast cancer that needs to be activated by cytochrome P450 2D6 (CYP2D6) into Zusammen-endoxifen (Z-END). Objective: The purpose of the study was to determine the association between CYP2D6*10 (c.100C>T) genotype and attainment of the plasma steady-state Z-END minimal threshold concentration (MTC) in Indonesian women with breast cancer. Methods: A cross-sectional study was performed in 125 ambulatory patients with breast cancer consuming TAM at 20 mg/day for at least 4 months. The frequency distribution of CYP2D6*10 (c.100C>T) genotypes (C/C: wild type; C/T: heterozygous mutant; T/T: homozygous mutant) was detected using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), the results of which were subsequently confirmed by sequencing. The genotypes were categorized into plasma Z- END concentrations of <5.9 ng/mL and ≥5.9 ng/mL, which were measured using ultra performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS). Results: Percentages of C/C, CT, and T/T genotypes were 22.4%, 29.6%, and 48.8%, respectively. Median (25-75%) Z-END concentrations in C/C, C/T, and T/T genotypes were 9.58 (0.7-6.0), 9.86 (0.7-26.6), and 3.76 (0.9-26.6) ng/mL, respectively. Statistical analysis showed a significant difference in median Z-END concentration between patients with T/T genotype and those with C/C or C/T genotypes (p<0.001). There was a significant association between CYP2D6*10 (c.100C>T) genotypes and attainment of plasma steady-state Z-END MTC (p<0.001). Conclusion: There was a significant association between CYP2D6*10 (c.100C>T) and attainment of plasma steady-state Z-END MTC in Indonesian breast cancer patients receiving TAM at a dose of 20 mg/day.
