Background: Quality of life (QoL) is an important tool for evaluating the effect of a disease as well as effects of treatment interventions. The present study is aimed to investigate QoL of the patients with various prevalent chronic diseases in Iran. Methods: In a cross-sectional study, 625 patients with one of the prevalent chronic diseases were assessed. Participants were recruited via convenient sampling method in special clinics of chronic diseases in three educational hospitals in Qazvin, Iran, from May to December 2016. Data were collected using WHOQOL-BREF and demographic questionnaire through interview. Data were analyzed using independent t-test, ANOVA, Pearson's correlation coefficient, and multiple linear regression method. Results: Significant difference in QoL scores was found in different chronic disease; patients with diabetes and hypertension had higher scores and patients with asthma and chronic obstructive pulmonary disease (COPD) had the lowest scores. Multivariate analysis showed that age, economic status, and type of disease were among the significant variables in predicting the QoL of the patients with chronic diseases. Conclusions: Some patients, such as those with asthma and COPD, had less QoL than other patients and should be prioritized while planning for the promotion of healthcare services. Due to the negative effects of economic status on QoL, the financial support programs should be among the major priorities of the patients' QoL improvement programs. [ABSTRACT FROM AUTHOR]

Objective To evaluate the possible involvement of programmed cell death strategy in hydatid cyst protoscolices following treatment with Myrtus communis ( M. communis ) as an herbal medicine. Methods Protoscolices were aseptically collected from sheep liver hydatid cysts. Evaluating the effect of M. communis extract on programmed cell death and increased activity of caspases 3, 8, and 9 in hydatid cyst protoscolices was conducted by treating the protoscolices with different concentration (5, 50, and 100 mg/mL) of M. communis extract at 37 °C and 5% CO 2 for 4 h by using the Bradford test and ELISA commercial kits. Results The extract of M. communis at all concentrations led to initiation of programmed cell death in protoscolices and this effect, was only significant at 50 and 100 mg/mL concentrations, compared to the negative control ( P < 0.05). Also, the activity of caspases 3, 8, and 9 in hydatid cyst protoscolices, was shown that the extract at all 3 concentrations could only increase the activity of caspases 3 and 9. Moreover, a significant increase in the activity of caspase 3 was only observed at concentrations 50 and 100 mg/mL by 37.00% and 66.19% while a significant increase in the activity of caspase 9 at the same concentrations was observed by 20.89% and 63.67%, respectively ( P < 0.05). Conclusions The extract of M. communis at different concentrations could increase the activity of caspases 3 and 9 and caused programmed cell death in hydatid cyst protoscolices however, this effect was significant at high concentrations of the extract.

Objective To evaluate the scolicidal and immunomodulatory effect of the Ziziphora tenuior ( Z. tenuior ) extract and its fractions. Methods Protoscolices were treated with six concentrations (3, 5, 10, 25, 50, and 100 mg/mL) of Z. tenuior extract and its fractions (ethanol, petroleum ether, ethyl acetate and chloroform) in periods of 10, 20, 30, 40, 50 and 60 min, and viability of protoscolices was evaluated using the 1.0% eosin. To examine the immunomodulatory effects of Ziziphora and its fractions on macrophage cells, the non-toxic concentration of extract and different fractions determined by MTT assay, and the Griess reaction was used to measure the level of nitrite as an indicator of nitric oxide by the macrophage cells in 10, 100 and 200 μg/mL in 24 h at 37 °C. Results In this study, the Z. tenuior extract at 10 mg/mL concentration was able to kill all protoscolices during 20 min. By increasing the concentration to 25 mg/mL, the scolicidal time reduced to 10 min. Regarding the effect of different fractions of Z. tenuior , the ethanolic fraction showed the highest scolicidal activity. The extract demonstrated an inhibitory effect on the activity of macrophages and reduced nitric oxide production. Although the petroleum ether and ethanolic fractions of the extract reduced nitric oxide production, nevertheless, this effect was only significant at 10 and 100 μg/mL concentrations ( P < 0.05). Conclusion The Z. tenuior extract and its fractions were effective against protoscolices yet the effect of total extract was considerable. Our findings indicates that the extract and its ethanolic and petroleum ether fractions could have anti-inflammatory properties. [ABSTRACT FROM AUTHOR]
