Attentional selectivity,automaticity, and self-efficacy predict simulator-acquired skill transfer to the clinical environment

Introduction

Several studies demonstrated that simulator-acquired skill transfer to the operating room is incomplete. Our objective was to identify trainee characteristics that predict the transfer of simulator-acquired skill to the operating room.

Postoperative development of sarcopenia is a strong predictor of a poor prognosis in patients with adenocarcinoma of the esophagogastric junction and upper gastric cancer

Background

There were few studies assessed the postoperative sarcopenia in patients with cancers. The objective of present study was to assess whether postoperative development of sarcopenia could predict a poor prognosis in patients with adenocarcinoma of esophagogastric junction, (AEG) and upper gastric cancer (UGC).

Influence of SNPs in cytokine-related genes on the severity of food allergy and atopic eczema in children

Although many single nucleotide polymorphism (SNP) studies have reported an association of atopy, allergic diseases and total serum immunoglobulin E (IgE) levels, almost all of these studies sought risk factors for the onset of these allergic diseases. Furthermore, many studies have analyzed a single gene and hardly any have analyzed environmental factors. In these analyses, the results could be masked and the effects of other genes and environmental factors may be decreased. Here, we described the correlation between four genes [interleukin (IL)-4 (C-590T), IL-4 receptor (A1652G), FCER1B (G6842A) and STAT6 (G2964A)] in connection with IgE production; the role of IL-10 (C-627A) as a regulatory cytokine of allergy; and the severity of food allergy (FA) and atopic eczema (AE) in 220 Japanese allergic children. In addition to these SNPs, environmental factors, i.e., patient's attitude, indoor environment, and so on, were also investigated in this study. Our study was retrospective, and the correlation was analyzed by our defined clinical scores divided into three terms: worst symptoms, recent symptoms and general amelioration at the most recent examination during the disease course. Our results indicated that IL-10 AA, the genotype with lower IL-10 production, is associated with higher IgE levels in the serum (p < 0.0001, estimate; 0.912). Marginal liver abnormalities were observed in the subject group with both FA and AE (p < 0.1191, estimate; 0.1490). Our defined clinical scores enabled evaluation of various aspects of disease severity. Based on the scores, while no single SNP selected in this study determined severity, the combination of the SNP with laboratory data and environmental factors appeared to determine severity.     

A case report: Severe bone marrow suppression caused by 6-mercaptopurin in Crohn's disease patient]

A 23-year-old man was admitted for treatment of acute exacerbation of ileitis and perianal abscess caused by Crohn's disease. After incision and drainage of the abscess, coupled with antibiotic therapy, 6-mercaptopurine (6-MP) was commenced. His white blood cell (WBC) count on day 12 after initiation of 6-MP was not decreased. However, on day 24 he was re-admitted because of severe myelosuppression (WBC: 300/microl), which was complicated by the recurrence of the perianal abscess. Myelosuppression was prolonged and required the administration of granulocyte colony stimulating factor (G-CSF). G-CSF was continued for 17 days to achieve recovery of his WBC count to a normal level.     

Beta2-glycoprotein I-dependent anticardiolipin antibody in early recurrent spontaneous abortion

The objective of this study was to assess the clinical significance of autoimmune anticardiolipin antibody that can react with cardiolipin only in the presence of beta2-glycoprotein I (beta2-glycoprotein I- dependent anticardiolipin antibody) in the pathogenesis of early recurrent abortion. A total of 72 early recurrent spontaneous aborters and 175 normal healthy women were analysed for the occurrence of beta2- glycoprotein I-dependent anticardiolipin antibody in serum samples by an enzyme-linked immunosorbent assay specific for the detection of beta2-glycoprotein I-dependent anticardiolipin antibody. The incidence of beta2-glycoprotein I-dependent anticardiolipin antibody in the early recurrent spontaneous aborters was essentially the same as that of normal women. Thus, the beta2-glycoprotein I-dependent anticardiolipin antibody seemed to have little, if any, implication in the pathogenesis of early recurrent spontaneous abortion.      

Approach to early diagnosis of acute mesenteric ischemia: evaluation in canine model

The high mortality rate of patients with acute mesenteric ischemia may be mainly due to the difficulty of making an early diagnosis. Many clinical and experimental studies have been attempted to make an early diagnosis in the view of history, physical examination, laboratory data, X-rays and angiographies. This study was undertaken to estimate the diagnostic value of twenty one laboratory parameters and three clinical parameters measured after superior mesenteric artery occlusion (SMAO) in the mongrel dogs. Consequently, the valuable diagnostic indicators of SMAO that statistically had significant difference were serum CPK isoenzyme-BB, serum CPK isoenzyme-MB, serum inorganic phosphate, serum calcium and base excess of arterial blood gas analysis. In these indicators, serum CPK isoenzyme-BB, serum inorganic phosphate and serum calcium were especially valuable indicators of its early diagnosis, because they showed significant change in the early phase after SMAO. However, other indicators showed significant change within eighteen hours after SMAO. Therefore, if these indicators are able to be examined in a case of abdominal emergency, they are considered to play a valuable role in the diagnosis of acute mesenteric ischemia.     

Ultrasonographic study on kidneys in patients with acute renal failure]

Ultrasonotomograms of 22 kidneys were obtained in 11 patients with renal-acute renal failure (renal-ARF). The underlying diseases of renal-ARF were acute tubular necrosis in 8 patients and acute on-set chronic glomerulonephritis in 3 patients. They were treated by hemodialysis in 10 patients and intermittent peritoneal dialysis in 1 patient. Ultrasonic measurement of the size of kidneys revealed that the thickness (anterior-posterior diameter) and the ratio of thickness to length (T/L) were greater in patients with ARF than in those with chronic renal failure and normal renal function. The patients with a low value of T/L (under 0.60) had a significantly greater urine volume than those with high a value of T/L (0.60 or more). The sonographic features of renal-ARF kidneys were marked increase in parenchymal echogenicity and appearance of hypoechoic swollen renal pyramids with sharpness of the corticomedullary border. In the course of ARF, these sonographic changes gradually disappeared when the patients had recovered from ARF. However, the prognosis was poor in patients with severer sonographic findings. We believe that repeated ultrasonic examination of the kidneys in patients with renal-ARF is useful for not only differential diagnosis of post-renal urinary obstruction but evaluating the course of ARF.
