The purpose of this study was to investigate the differences between pre- and postoperative pituitary hormone levels in patients undergoing surgical resection of pituitary adenoma and to identify factors associated with preoperative hypopituitarism. Data from 81 patients with histologically confirmed functioning and non-functioning pituitary adenomas (NFPA) who underwent transsphenoidal resecti...

Objective: To investigate the relationship between immune function and perioperative sepsis in HIVpositive patients. Methods: Retrospective analysis of 144 HIV-positive patients surgically treated from Oct 2008 to Dec 2010 in Shanghai Public Health Clinical Center. The patients were divided into four groups based on their CD4T cells counts in preoperative period: group A (0 99 cell/ul), group B...

many of injured children will require surgical treatment with involvement of the anesthesiologist. the anesthesia providers may have to take care of pediatric patients on following occasions: 1- initial stabilization in the emergency department 2- providing sedation and monitoring for imaging 3- preoperative management of emergent surgical procedures such as laparotomy or craniotomy 4- manageme...

Elective Coronary Artery Bypass Graft (CABG) surgery using cardiopulmonary bypass techniques following preoperative transfusions to increase the hemoglobin A levels to above 60%, in a male patient with sickle cell disease [SCD] is described. Avoidance of hypoxia and acidosis lead to an uneventful perioperative period. Our institutional protocol for preoperative transfusions is highlighted.

Although dual-task interference is ubiquitous in a variety of task domains, stop-signal studies suggest that response inhibition is not subject to such interference. Nevertheless, no study has directly examined stop-signal performance in a dual-task setting. In two experiments, stop-signal performance was examined in a psychological refractory period task, in which subjects inhibited one respon...

The standard bottleneck model of the psychological refractory period (PRP) assumes that the selection of the second response is postponed until the first response has been selected. Accordingly, dual-task interference is attributed to a single central-processing bottleneck involving decision and response selection, but not the execution of the response itself. In order to critically examine the...

We generalize the classical Cayley-Dickson doubling process starting with a quaternion algebra over a field F by allowing the scalar in the doubling to be an invertible element in the algebra. We investigate the resulting eight-dimensional algebras over F and show that they are division algebras for all scalars chosen in D outside of the base field F , if D is a division algebra.

The hypothesis that episodic memory retrieval can occur in parallel with other cognitive processes was tested in 2 experiments. Participants memorized words and then performed speeded cued recall (Experiment 1) or speeded yes-no recognition (Experiment 2) in a dual-task situation. The psychological refractory period design was used: The participant was presented with a single test item at vario...

OBJECTIVE to examine the association between preoperative body weight, adherence to postsurgical nutritional follow-up, length of postoperative period, and weight loss during the first 18 months among adults who have undergone bariatric surgery. METHODS a retrospective cohort study was conducted on 241 consecutive patients who underwent open Roux-en-Y gastric bypass (RYGBP) from January 2006 ...

BACKGROUND Post-operative atrial fibrillation is an important complication after coronary bypass surgery. As inflammation and oxidative stress were makedly encountered in the etiology, high cholesterol was also defined to provoke atrial fibrillation. In this present study, the relationship between postoperative atrial fibrillation and preoperative serum lipid levels were evaluated. METHODS A ...
