Abstract The current study aims to improve the quality of wastewater collected from the secondary sedimentation tank of Hamdan sewage water treatment plant, Basrah, Iraq, using C. demersum L. for phytoremediation potential in the laboratory experiment. The experiments were also designed to establish some toxicological effects of wastewater on plant physiology as a response to wastewater stresses. The selected physio-chemical parameters of wastewater were conducted. Plant analyses were also measured before and after 21st day of exposure. The results showed the efficiency of the plant in improving the water quality in a different ratio. The dilution 1:3 (T3) was the most efficient with a significant difference (p<0.05) between treatment and control for most of the measured parameters. The result showed the efficiency of Ceratophyllum demersum in removing the Total hardness, Ca+2, Mg+2, BOD5, COD, NO3-2, PO4-2, Na+ and Cl- in 1:3 dilution (55.88, 13.27, 89.55, 90, 47.37, 50.65, 48.51, 16.28 and 40.24)% compared with (17.65, 5.42, 27.31, 50, 15.79, 16.30, 13.86, 6.73 and 15.77 )% in control respectively. The Ceratophyllum demersum plant has proven to be effective in improving the quality of wastewater, and therefore it can be considered an effective candidate in phytoremediation technology.

Abstract Background The consequences of obstetric fistula on affected women are more than the medical condition. It has extensive physical, psychological, social, and economic consequences on them. Obstetric fistula affects the entire health and entire life of women. Women suffering from obstetric fistula are often abandoned by her partner, relatives, and the community. This study aimed to determine the quality of life of obstetrics fistula patients before and after surgical repair. Methods Institutional-based prospective, before and after study design was conducted in the Jimma University Medical Center from November 1, 2019–October 30, 2020. A face-to-face interview was conducted with fistula patients who visited Jimma University Medical center, fistula clinic during the study period. All fistula patients were included in the study. Accordingly, 78 women who underwent surgical repair were interviewed. The means and the standard deviation were computed using conventional statistics formulas. The unpaired t-test was used to compare two independent means, and one-way analysis of variance (ANOVA) was used to compare the quality of life before repair and after a successful repair. Linear regression analysis was done for identifying determinants of quality of life. A P value of 0.05 will be considered statistical significance. Result The overall quality of life of women was 58.17 ± 7.2 before the surgical repair and 71.20 ± 10.79 after surgical repair. The result indicates there is a significant difference in the mean value of pre and post-operative (P < 0.001). The overall satisfaction of women with their health status before the surgical repair was 22.5 ± 1.30and it has increased to 53.0 ± .90after surgical repair. The physical health dimension score was 16.51 ± 5.27 before the surgical repair while it has increased to 21.77 ± 5.38 after the surgical repair. The score of the social domain before the surgical repair was 5.19 ± 1.34 and it has increased to 7.13 ± 3.67 after the surgical repair. The score of the environmental health domain was 17.41 ± 2.89 before the surgery while it also increased to 21.65 ± 4.04 after the surgical repair. The results have shown there was a significant difference in the mean values of pre and post-operatives in both social and environmental scores (P < 0.001). The score of the psychological health domain before the surgery was 19.06 ± 1.46 and it was increased to 19.84 ± 3.21 after the surgical repair. The result showed there is a significant difference in mean value pre and post-operative (P = 0.048), though it is a slight improvement compared to other domains. Conclusion The overall quality of life of the patient with fistula was improved after successful surgical repair. Although all domains of quality of life had shown significant improvement after successful surgical repair, the psychological domain showed slight improvement.

Background/aims Workers engaged in vehicle spray painting are at a risk of developing respiratory problems because of the solvents in the spray paints. Changes in respiratory functions and functional capacities caused by spray painting can be improved with respiratory exercises. The aim of this study was to examine the effects of respiratory exercises on the respiratory functions, functional capacity and quality of life in vehicle spray painters. Methods A total of 70 volunteers with similar characteristics participated in the study. The groups were divided into two groups randomly (35 study group, 35 control group). Respiratory functions (value of forced expiratory volume percentage in 1 second [FEV1]), forced vital capacity percentage [FVC], FEV1/FVC percentage, peak expiratory flow percentage [PEF (%)] and maximum voluntary ventilation percentage [MVV (%)]), functional capacity (6-Minute Walk Test) and quality of life (Short Form Health Survey [SF-36]) were evaluated. The study group undertook supervised breathing exercises 3 days a week for 6 weeks. The same exercises were given to the control group as a home programme. Home programmes were followed up by telephone calls. Evaluations were performed again after 6 weeks. Results In the study group, FEV1 (%) increased more than in the control group (P<0.05). The increase in PEF (%) was similar in both groups (P>0.05). In the study group, FEV1/FVC (%) and MVV (%) were significantly different before and after the intervention (P<0.05), but there was no difference in the control group (P>0.05). There was a greater increase in the study group than in the control group (P<0.05). 6-Minute Walk Test distance (m) before and after the intervention in both groups were similar (P>0.05). Before and after the intervention, a significant difference was found in the vitality and the social function domains of the SF-36 in the study group. In the comparisons of groups, a significant difference was found in the study group in the role-emotional, social function and bodily pain domains of the SF-36 after the intervention (P<0.05). Conclusions Breathing exercises can be recommended for vehicle spray painters to avoid an increase in respiratory resistance and to improve their quality of life.

Background: Thalassemia is the most common autosomal abnormality in Syria. Its complications have an important effect on education; time off school; sport; difference from friends/ siblings; social interactions; and stigmatization. Knowledge of factors associated with quality of life in thalassemia patients is necessary for forming appropriate clinical programs, social support, and improving treatment outcomes. Purpose: The study was to assess the effects of Patients' and Care-givers' Knowledge, Attitude, & Practice (KAP) with Quality of Life among Thalassemia Major Patients' in Syria. Methods: Cross-sectional descriptive analytical design was conducted at the national thalassemia center in Damascus. WHOQOL-BREF and a questionnaire developed by the researcher were used to measure the participants’ knowledge, attitudes and practices of thalassemia. Results: Total of 238 thalassemia patients participated in the study. A statistical significance was found regarding improvement of skill and knowledge scores among caregivers and thalassemia patients before and after receiving the teaching guide from 12.52±1.77 to 14.07±1.01, t=11.447, p=0.000 and from 34.12±4.50 to 37.43±4.61, t=-8.58, p= .000 respectively. Stigmatization was significantly noticed among families caring for thalassemic patients. There were a significant differences in the mean score regarding nutritional status before and after teaching guide paired t test= 12.11, p= 0.000. A statistical significance was found in females regarding social domain p=0.04. However, mean scores for overall quality of life were better in females rather than males, but these mean scores were statistically insignificant p>0.05. A statistical significant difference in ferritin levels and patient’s age was found. Results also revealed that no statistical significant differences was observed between overall quality of life of the four domains in relation to the two treatment groups (subcutaneous vs oral) and age groups. Conclusion: Thalassemia is a socio-economic problem. The most efficient way to reduce risks of having affected patients is by increasing the knowledge through training of parents regarding the disease. Our findings highlighted that there was lack in patients’ knowledge and skills regarding the disease, but a remarkable improvement in both knowledge and performance was found after patients received the teaching guide, which lead to an increase in overall patient's quality of life.
