Date seed extract as preservatives

The increasing demand for minimally-processed. extended shelflife foods and rcpons of ehemical preservatives as having potential toxicity demands food manufacturers to find altcrnative snurccs of anTimicrobial compounds. Food infection and into.~ication are considered as the most common causes of foodborne dir.eases worldwide.

Involved-site radiation therapy by volumetric modulated arc therapy versus 3D- conformal radiotherapy for treatment of stages I and II supra-diaphragmatic Hodgkin’s lymphoma

Purpose: Based on the observation that recurrences of Hodgkin's lymphoma (HL) typically occur in sites of initial nodal involvement the need to concise radiotherapy to only involved nodes that was termed as involved nodal radiotherapy (INRT) or of involved site lymph nodes, involved-site radiation therapy (ISRT) is starting to be widely accepted to use in early stage HL. We aimed in our study to compare between volumetric modulated arc therapy (VMAT) and 3D-conformal radiotherapy (3D-CRT) in radiation of early stage supra-diaphragmatic HL.Methods: The clinical and dosimetric data of 34 patients affected with stages I and II supra-diaphragmatic HL, treated between January 2011 and September 2015 with combined modalities therapy in a single institution were analyzed. Patients received 2-8 cycles of combination chemotherapy ABVD (Adriamycin, Bleomycin, Vinblastine &amp; Dacarbazine) on days 1 and 15 repeated every 28 days. The clinical target volume (CTV) was contoured based on the pre-chemotherapy CT and PET-CT scans. Modification of the CTV was done according to post-chemotherapy anatomical changes. The radiation dose given was 30 Gy/15 fractions.Results: After a median follow up period of 30 months, the progression free survival (PFS) and overall survival (OS) in both groups were 100%. Oropharengeal mucositis was the commonest toxicity in both groups. There was no statistically significant deference between the acute radiation toxicities in both groups. The Dmean valuefor lung was higher in 3D-CRT than VMAT (12.0 ± 6.1 Gy vs. 9.9 Gy ± 8.6 Gy). For the breasts volume, the V5Gy was slightly higher for 3D-CRT compared with VMAT at, 7.6% and 6.5% respectively. For the heart, V5Gy and V10Gy valueswere higher for the RA than for 3D-CRT accounting for (51.9 ± 28.9%) and (41.0 ± 24.6%) versus (40.0 ± 25.9% and 30.7 ± 22.5%) respectively. Thyroid gland mean dose was lower for VMAT (21.8 ± 7.7 Gy) than for 3D-CRT (26.8 Gy ± 4.1 Gy) but did not reach statistically significant value (P = 0.06).Conclusion: Involved-site VMAT technique is safe and effective in term of providing excellent local control and survival following ABVD-based chemotherapy

Gender Differences in Presentation, Management, and In-Hospital Outcomes for Patients with AMI in a Lower-Middle Income Country: Evidence from Egypt

BACKGROUND: Many studies in high-income countries have investigated gender differences in the care and outcomes of patients hospitalized with acute myocardial infarction (AMI). However, little evidence exists on gender differences among patients with AMI in lower-middle-income countries, where the proportion deaths stemming from cardiovascular disease is projected to increase dramatically. This study examines gender differences in patients in the lower-middle-income country of Egypt to determine if female patients with AMI have a different presentation, management, or outcome compared with men. METHODS AND FINDINGS: Using registry data collected over 18 months from 5 Egyptian hospitals, we considered 1204 patients (253 females, 951 males) with a confirmed diagnosis of AMI. We examined gender differences in initial presentation, clinical management, and in-hospital outcomes using t-tests and χ(2) tests. Additionally, we explored gender differences in in-hospital death using multivariate logistic regression to adjust for age and other differences in initial presentation. We found that women were older than men, had higher BMI, and were more likely to have hypertension, diabetes mellitus, dyslipidemia, heart failure, and atrial fibrillation. Women were less likely to receive aspirin upon admission (p<0.01) or aspirin or statins at discharge (p = 0.001 and p<0.05, respectively), although the magnitude of these differences was small. While unadjusted in-hospital mortality was significantly higher for women (OR: 2.10; 95% CI: 1.54 to 2.87), this difference did not persist in the fully adjusted model (OR: 1.18; 95% CI: 0.55 to 2.55). CONCLUSIONS: We found that female patients had a different profile than men at the time of presentation. Clinical management of men and women with AMI was similar, though there are small but significant differences in some areas. These gender differences did not translate into differences in in-hospital outcome, but highlight differences in quality of care and represent important opportunities for improvement
