Dietary Ruminant and Industrial Trans-Fatty Acids Intake and Colorectal Cancer Risk
No full textAs colorectal cancer (CRC) is largely due to modifiable lifestyle habits, the awareness on its risk factors is highly important. Dietary fatty acids have been linked to CRC risk. We explored the association between dietary trans fatty acids (TFAs) intake and CRC risk. We analyzed 865 CRC cases (434 in colon and 404 in rectum) and 3206 controls of the IROPICAN study, with data collected by trained interviewers using validated questionnaires. TFAs intake (industrial and ruminant types) was categorized into quartiles. Multivariate logistic regression models were built to calculate the odds ratios (OR) for the association between CRC and TFAs. We observed a positive association between industrial TFAs and colon cancer (OR for highest vs lowest quartile [ORQ4vsQ1] = 1.28, 95% confidence interval 1.07–1.54). A higher association was observed between industrial TFAs and CRC, occurring after 50 years of age. In addition, elaidic acid was associated with an increased risk of colon (ORQ4vsQ1 = 1.58, 1.24–2.02) and specifically of proximal colon cancer (OR Q4vsQ1 = 2.12, 1.40–3.20), as well as of rectum cancer (ORQ4vsQ1 = 1.40, 1.07–1.83). An inverse association was observed between ruminant TFAs intake and colon cancer risk (ORQ4vsQ1 = 0.80, 0.67–0.97). Industrial TFAs, such as semisolid/solid hydrogenated oils, may increase the risk of CRC, especially colon and proximal colon cancer. In contrast, ruminant TFAs do not appear to be associated with CRC. Awareness programs and regulatory actions regarding hydrogenated oils are warranted, given their high consumption through ultra-processed foods in more developed and less developed countries
The Role of Islamic Architecture in Promoting the Quality of Life
No full textAll religions and schools of thought represent their specific ideas about nature, natural elements and its relationship with man in such a way that studying them can help explain their influences on shaping the environmental surroundings. Recent debates prove that majority of discussions are focused in protection and conservation of nature and it is implying that man’s need is restricted to elimination of pollutions. In other words, solving his problems, related to nature seems to be the only concern while it is necessary to pay attention to the quality and quantity of life equally. In Islamic culture, deliberation on the nature and discovering the dominant rules, play a vital role as nature and its components are considered as divine symbols to guide man toward recognition of nature and also a mutual relationship between man and nature can be used to construct a suitable environment in harmony with existed regularity in nature. This research is based qualitative method and gathering date by library studies and collecting information. The conclusion of this research show that in Islamic civilization specially visual art, architecture and urbanism, naturalistic motivation are investigated to present manifestation of Islamic art and natural aesthetic, this cycle is eternal and can help a man to recognize the nature
Outcome of single-piece intraocular lens sulcus implantation following posterior capsular rupture during phacoemulsification
No full textPurpose: To assess the safety and outcome of single-piece posterior chamber intraocular lens (PC-IOL) implantation in the ciliary sulcus following posterior capsular rupture during cataract surgery.
Methods: Patients with posterior capsular rupture during cataract surgery with a single-piece acrylic IOL implanted into the ciliary sulcus were studied. complete ocular examinations were performed after 6 months postoperatively.
Results: Twenty-four eyes were included. Mean follow-up duration was 8.33 ± 2.33 months. There was no significant difference between preoperative and postoperative keratometric cylinder or intraocular pressure. Visual acuity of 87.50% of patients was ≥20/40 after surgery. complications included foveopathy (10 eyes), iris transillumination defect (4 eyes), iris chafing (2 eyes), pigmented keratic precipitate (KP) (4 eyes), clinical IOL tilt (6 eyes), endothelial pigment dusting (14 eyes), IOL pigment dusting (17 eyes), iris bowing (6 eyes), IOL decentration (4 eyes), and IOL tilt detected with ultrasonography biomicroscopy (UBM) (4 eyes). IOL pigment dusting was significantly higher in eyes with short axial lengths, high IOL power, small sulcus-to-sulcus (STS) diameter, large STS IOL diameter mismatch, and small anterior chamber depth and angle. Significant relationships were observed between pigmented KP with small STS diameter and large STS IOL diameter mismatch, UBM and clinical IOL tilt with large anterior chamber depth and between iris transillumination defect and STS IOL diameter mismatch.
Conclusion: This implantation is associated with higher incidence of complications. Single-piece acrylic IOLs are not designed for sulcus implantation. However, they may be used in eyes with longer axial length if the 3-piece IOL is not available

No full textFactors related to women's childbirth satisfaction in physiologic and routine childbirth groups
No full textBackground: Women's satisfaction with childbirth is an important measure of the quality of maternity care services. This study aims to address factors related to women's childbirth satisfaction in physiological and routine childbirth groups. Materials and Methods: This descriptive-analytical study was conducted among 340 women in physiological and routine childbirth groups in 2012. Women were selected through convenience sampling method in the routine group and by census in the physiological group. Data were collected using a 5-part questionnaire composed of demographic and obstetrics details, Mackey's Childbirth Satisfaction Rating Scale (CSRS), satisfied with birth setting, Labor Agentry Scale (LAS), and Visual Analogue Scale (VAS), which was completed by interview 24 hours after childbirth. Data were analyzed using the Statistical Package for the Social Sciences version 18 software using Pearson correlation test, independent t-test, analysis of variance, and linear, multivariate regression model at the significant level of P 0.05). Conclusions: Improved physical structure and setting of birth room, nonmedical pain relief, mothers' involvement in the process of labor, and sense of being in control are associated with mothers' satisfaction
