Background: Breast cancer is the most common malignancy affecting the Iraqi population and the leading cause of cancer related mortality among Iraqi women. It has been well documented that prognosis of patients depends largely upon the hormone receptor contents and HER-2 over expression of their neoplasm. Recent studies suggest that Triple Positive (TP) tumors, bearing the three markers, tend to exhibit a relatively favorable clinical behavior in which overtreatment is not recommended. Aim: To document the different frequencies of ER/PR/HER2 breast cancer molecular subtypes focusing on the Triple Positive pattern; correlating those with the corresponding clinico-pathological characteristics among a sample of Iraqi patients diagnosed with the disease. Patients and Methods: This retrospective study involved 570 female patients diagnosed with breast cancer who visited the Main Referral Center for Early Detection of Breast Cancer and the National Cancer Research Center. The requested data was mainly extracted from an established information system database, developed by the principal author over a 4-years period from 2012 to 2016. The registered information comprised data related to clinical presentation, diagnostic and pathologic findings. ER, PR and HER2 status were analyzed immunohistochemically and the detected profiles were correlated with the corresponding clinico-pathological characteristics. Results: The rates of ER (+), PR (+) and HER-2 (+) tumors were 66.8%, 64% and 29.3% respectively. The tumor marker expression status was documented in eight subtypes; 83 cases (14.6%) of the examined breast carcinomas were categorized as ER+/PR+/HER2+ (Triple Positive/Luminal B), 89 cases (15.6%) were ER-/PR-/HER2- (Triple Negative), 241 (42.2%) were ER+/PR-/HER2- (Luminal A) while 67 (11.8%) showed ER-/PR-/HER2+ expression (HER-2 variant). No significant variations were noted when comparing age, menopausal status and tumor grade of Luminal B pattern to Luminal A and the rest of the studied subtypes. Although our data revealed a statistical difference with respect to the distribution of tumor types; where infiltrative ductal carcinoma constituted the major histology among patients with Triple Positive/Luminal B subtype (86.7% as compared to 67.6% in Luminal A), nevertheless, more than two third of those patients (67.4%) were diagnosed at earlier stages (I and II) compared to 55.2% of those in the remaining groups. Conclusions and Recommendations: Our findings support the hypothesis that the Triple Positive subtype might be driven primarily by the hormone receptor status. Further comprehensive surveys are recommended to focus on the intrinsic interactions and tumor cell heterogeneity of that pattern to avoid overtreatment and predict accurate response to therapy.

Objectives:
To evaluate mothers’ attitudes toward readiness for discharge care at home for a premature baby in Intensive Care Unit at teaching hospitals in Medical City Complex and to find out the relationship between mothers’ attitudes and their socio-demographic characteristics.
Methodology: A quasi-experimental study design was carried out through the period of 6th January 2020 to 2021 to 11th March 2021, to evaluate mother’s attitude toward discharge care plan for premature babies. The study carried out in Welfare Teaching Hospital, Nursing Home Hospital and Baghdad Teaching Hospital at Medical City Complex in Baghdad City on 30 mother of premature babies in neonatal intensive care units using the nonprobability sampling

Background: With the increasing demands for adult orthodontics, a growing need arises to bond attachments to porcelain surfaces. Optimal adhesion to porcelain surface should allow orthodontic treatment without bond failure but not jeopardize porcelain integrity after debonding.The present study was carried out to compare the shear bond strength of metal bracket bonded to porcelain surface prepared by two mechanical treatments and by using different etching systems (Hydrofluoric acid 9% and acidulated phosphate fluoride 1.23%). Materials and Methods: The samples were comprised of 60 models (28mm *15mm*28mm) of metal fused to porcelain (feldspathic porcelain). They were divided as the following: group I (control): the porcelain surface left u

The first depends on the oxidative coupling of eugenol with p-amino-N,N-dimethylaniline (PADA) in the presence of K3[Fe(CN)6]. A linear regression calibration plot for eugenol was constructed at 600 nm, within a concentration range of 0.25-2.50 μg.mL–1 and a correlation coefficient (r) value of 0.9988. The limits of detection (LOD) and quantitation (LOQ) were 0.086 and 0.284 μg.mL–1, respectively. The second method is based on the dispersive liquid-liquid microextraction of the derivatized oxidative coupling product of eugenol with PADA. Under the optimized extraction procedure, the extracted colored product was determined spectrophotometrically at 618 nm. A l
