Background: Survival after hospital admission has been evaluated as a possible risk factor for long-term mortality in selected classes of diseases. The aim of this study was to evaluate survival after hospital admission in all patients admitted as in-patients in a general hospital of Milano, Italy. Methods: 2,580 consecutive patients admitted at Ospedale San Paolo, July1-December 31, 2012, for several classes of diseases (internal medicine, cancer, infectious diseases, trauma and surgery, pneumonia, and heart diseases) were studied; age, total diseases, type of admission, length of admission, age-adjusted Charlson index, prognostic nutritional index (PNI), and full blood count were evaluated. Results: At univariate analysis, all investigated variables, except sex and lymphocytes, were associated with death of patients. At stepwise regression analysis, Charlson index or age plus total diseases, type of admission, number of admissions, and PNI were significant risk factors in the whole sample and in the majority of classes of diseases. Conclusion: Pre-existing conditions and nutritional state represent the major risk factor for mortality in most classes of disease, and possibly influence other predictors, such as type of admission, length of stay. This suggests that the current model of hospital admission might be improved, for instance through comprehensive care at home, instead of hospital admission, or before admission.

A sequence biostratigraphic analysis has been done for the Upper Cretaceous-Lower Paleogene sedimentary outcrops at Wadi Raha, Sudr El-Hetan and Wadi El-Giddi areas in west-central Sinai. The sequences are subdivided into four carbonate rock units; from base to top: the Wata, Themed, Sudr and Waseiyit formations. The biostratigraphic analysis of the studied samples led to the identification of two main planktonic foraminiferal zones, three benthic foraminiferal zones with the ammonite zone. Eleven microfacies associations are recorded in the rock units. Nine constitutes a limestone facies with one constitutes a dolostone facies and one a claystone facies. The stratigraphic data, and the facies study support the identification of three major breaks (sequence boundaries) and four depositional sequences. The depositional sequences are subdivided into four supercycles and seven cycles of 3rd order. The oldest break (∼90-88.5Ma.) exists at the top of the Wata Formation coincides with the intra Turonian drop in the global sea level with the initiation of the Syrian Arc inversion phase. The second major break (85 - ∼75Ma.) coincides with the major inversion phase and the evolution of the doubly plunging anticlines. The third major break (∼68 through ∼53Ma.) represents the last phase of the Syrian Arc inversion and complete the missing of Paleocene sequences.
