Simple Nutritional and Inflammatory Markers Associated with Bed Sores in Elderly Stroke People

Advances in Aging Research 2016年第2期5卷 58-69页

作者： Mohammed Zein Abdulwadood safaa hussein ali Geriatrics and Gerontology Department Faculty of Medicine Ain Shams University Cairo Egypt

Background: Bed sores are major burden to hospital care and usually associated with worse prognosis and longer hospital stay. Aims: To evaluate whether simple biochemical inflammatory and nutritional markers would differ between those with bedsores and those without in elderly stroke patients and if there is a distinction between recent bed sore stroke patients and old bed sore stroke patients as regard these biomarkers. Methods: 80 Stroke elderly patients were enrolled and divided into four groups: patients with recent stroke who developed bedsores, patients with recent stroke who did not develop bedsores, patients with old stroke who developed bedsores and patients with old stroke who did not develop bedsores. Nutritional markers (albumin, total protein, magnesium, iron, total iron binding capacity (TIBC), hemoglobin and cholesterol) and inflammatory markers (total leucocyte count, neutrophil to lymphocyte ratio and ferritin) were compared between the four groups. Results: Concerning nutritional markers, albumin (P =< 0.001), Alb/Pr ratio (P =< 0.001), TIBC (P =< 0.001) and cholesterol (P = 0.005) are lower in the acute stroke with bed sore patients versus acute stroke without bed sore. Lower albumin (P =< 0.001) is only found in comparison between chronic stroke with bed sore patients and chronic without bed sore patients. There is a difference between acute stroke with bed sore and chronic stroke with bed sore concerning albumin (P =< 0.001), TIBC (P =< 0.001) and TG (p =< 0.001). Albumin is lower while TG and TIBC are higher in those with acute stroke with bed sores. Regarding inflammatory markers, high neutrophil and ferritin (p =< 0.001) were found in acute stroke with bed sore patients versus acute stroke without bed sore. No difference was found between chronic stroke with bed sore patients and chronic stroke without bed sore patients. Acute stroke with bed sore group has higher TLC, neutrophil, neut/lymph ratio and ferritin (p =< 0.001) than chronic stroke

Frontiers of Nursing 2018年第4期5卷 277-284页

作者： Manal Hamed Mahmoud safaa hussein Mohammad Medical-Surgical Nursing Faculty of Nursing Benha University Medical-Surgical Nursing Faculty of Nursing Zagazig University

Objective: Ileus usually occurs after abdominal surgery and is allied with complication and delays recovery. It is hypothesized that chewing gum reduces postoperative ileus by improving early recovery of gastrointestinal function. This study aimed to explore whether chewing gum after appendectomy accelerates the recovery of gastrointestinal ***: Randomized control trial was used in this study. This study was conducted in the General Surgery Department at Zagazig University Hospital. A total of 240 patients undergoing appendectomy were involved in this study; they were divided into the chewing sugar-free gum group(120) and the control group(120). Two tools were utilized in this study. Tool I: Structured Interviewing Schedule: part 1: assessment of personnel characteristics. Part 2: assessment of anthropometric measurements of the studied subjects as well as pre-and intraoperative indicators of them. Tool II: postoperative assessment sheet: assessed postoperative parameters of the intestinal function, occurrence of postoperative ileus, and related symptoms were assessed among studied ***: There were highly significant statistical differences in the time of resumption of gastrointestinal functions and postoperative ileus symptoms between the two groups(Palization of gastrointestinal function. Chewing sugar-free gum after abdominal surgery is recommended to be added to the protocol of nursing care in the surgery units as well as its involvement in the nursing curriculum.

Based on current voltage（I-Vg） and capacitance voltage（C-Vg） measurements,a reliable procedure is proposed to determine the effective surface potential Vd（Vg） in Schottky *** the framework of thermionic emission,our analysis includes both the effect of the series resistance and the ideality factor,even voltage dependent. This technique is applied to n-type indium phosphide（n-InP） Schottky diodes with and without an interfacial layer and allows us to provide an interpretation of the observed peak on the C-Vg *** study clearly shows that the depletion width and the flat band barrier height deduced from C-Vg,which are important parameters directly related to the surface potential in the semiconductor,should be estimated within our approach to obtain more reliable information.
