BACKGROUND Recently, the ImmuKnow assay (Cylex Inc., Columbia, Md) has been reported to be a global immune monitoring tool for organ transplants recipients. We assessed whether immunKnow ATP values predicted infectious syndromes. METHODS We prospectively enrolled 71 kidney transplant patients between September 2008 and May 2011. lmmuKnow assay monitoring was performed at one dav before as well as 4, 8, 12, 16, 20, 24, 36, and 52 weeks after the operation. ImmuKnow assay values were compared as well as BK viral infection pre-infection(PI), at first detection of infectious syndrome (DI), 4 weeks there after (4W), 8 weeks there after (8W) and 12 weeks there after (12W) and pre-recovery (PR), recovery (R) times. RESULTS Serial ImmuKnow assays showed significant differences over time and BK viral infectious state (P =.026). Interestingly, PI was significantly lower than DI and PR but PR significant greater than PI, 8W and 12W. However, we did not observe an adequate or absolute cutoff value of ImmuKnow by ROC curve: 377 ng/mL ImmuKnow showed 0.471 of AUC and 57.1% and 56.2%, of sensitivity and specificity. CONCLUSION Longitudinal evaluation and adjustment of the value of ImmuKnow assay seemed to be a favorable modality to monitor infectious syndromes especially those involving BK virus.

Three single nucleotide polymorphisms (SNPs) in the porcine MYOD1 gene were used for association analysis and haplotype construction to evaluate the effects of their substitution. Four hundred and three pigs of Yorkshire and Berkshire breeds were used. The mRNA expression levels of MYOD1 were examined. The g.489C>T and g.1264C>A SNPs were significantly associated with several muscle fiber characteristics, the loin eye area, and lightness. Particularly, animals having hetero-genotypes of both sites showed good performance both in lean meat production and meat quality traits. The results of haplotype substitution were similar to the associations of individual SNPs. Moreover, the 2 SNPs had significant effects on mRNA expression. Therefore, the g.489C>T and g.1264C>A SNPs in MYOD1 may be meaningful DNA markers that can be used for improving important porcine economic traits.

OBJECTIVE: To investigate the association among religiosity and depression, anxiety, and quality of life in women with breast cancer. METHOD: The sample consisted of 284 patients with breast cancer who were undergoing surgery. They were assessed with the following instruments at baseline and at 1 year after surgery: the Duke Religious Index (DRI), the Montgomery-Asberg Depression Rating Scale, the Hospital Anxiety Depression Scale, and the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire Core 30. Depression was diagnosed with the Mini International Neuropsychiatric Interview. RESULTS: The prevalence of depression at baseline and at 1 year was 22.5% and 16.5%, respectively. The religious groups did not differ significantly with respect to the prevalence of depression or scores on psychiatric measures at either baseline or at 1 year. The prevalence of depression significantly decreased only in the Protestant group, from 30.1% to 15.7%. Scores on the DRI were significantly negatively correlated with scores on all of the anxiety and depression scales at 1 year after surgery in this group. In contrast, scores on the religious activity subscale of the DRI were significantly positively correlated with scores on the Hospital Anxiety Depression Scale at baseline or at 1 year among Catholic participants. The DRI scores of Protestant respondents were significantly positively correlated with scores on the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire Core 30 at 1 year after surgery. CONCLUSION: Religiosity plays an important role in the emotional state and quality of life of Korean women with breast cancer. However, its clinical meaning may differ according to the type of religious affiliation and the stage of illness. Copyright © 2012 John Wiley & Sons, Ltd.

PURPOSE Emergency operations for perforated peptic ulcer are associated with a high incidence of postoperative complications. While several studies have investigated the impact of perioperative risk factors and underlying diseases on the postoperative morbidity after abdominal surgery, only a few have analyzed their role in perforated peptic ulcer disease. The purpose of this study was to determine any possible associations between postoperative morbidity and comorbid disease or perioperative risk factors in perforated peptic ulcer. MATERIALS AND METHODS In total, 142 consecutive patients, who underwent surgery for perforated peptic ulcer, at a single institution, between January 2005 and October 2010 were included in this study. The clinical data concerning the patient characteristics, operative methods, and complications were collected retrospectively. RESULTS The postoperative morbidity rate associated with perforated peptic ulcer operations was 36.6%(52/142). Univariate analysis revealed that a long operating time, the open surgical method, age (≥60), sex (female), high American Society of Anesthesiologists (ASA) score and presence of preoperative shock were significant perioperative risk factors for postoperative morbidity. Significant comorbid risk factors included hypertension, diabetes mellitus and pulmonary disease. Multivariate analysis revealed a long operating time, the open surgical method, high ASA score and the presence of preoperative shock were all independent risk factors for the postoperative morbidity in perforated peptic ulcer. CONCLUSIONS A high ASA score, preoperative shock, open surgery and long operating time of more than 150 minutes are high risk factors for morbidity. However, there is no association between postoperative morbidity and comorbid disease in patients with a perforated peptic ulcer.

The sinking skin flap syndrome is a rare complication after a large craniectomy. It consists of a sunken skin above the bone defect with neurological symptoms such as severe headache, mental changes, focal deficits, or seizures. In patient with sinking skin flap syndrome, cerebral blood flow and cerebral metabolism are decreased by sinking skin flap syndrome, and it may cause the deterioration of autoregulation of brain. We report a case of a patient with sinking skin flap syndrome who suffered from reperfusion injury after cranioplasty with review of pertinent literature.

Although biphasic head-shaking nystagmus (HSN) is a basic response to head shaking in patients with unilateral vestibular loss, monophasic HSN is commonly seen in patients with dizziness of undetermined etiology. Since the clinical significance of HSN remains unclear, we sought to characterize different types of HSN in patients with vestibular neuritis (VN) during the acute stage (within 7 days after the onset of vertigo) and at follow-up (about 2 months after the onset of vertigo), and to compare HSN and caloric responses. We analyzed HSN, spontaneous nystagmus and caloric tests in 66 patients with VN. Overall, HSN showed high abnormal rates (94 and 89%) during the acute and follow-up stages and could detect vestibular hypofunction even when canal paresis (CP) had normalized at follow-up. All patients in the acute stage and most patients at follow-up showed HSN with the slow phase to the lesioned side (paretic). Biphasic HSN was common at follow-up, and many patients with a monophasic paretic pattern during the acute stage had evolved to a biphasic paretic pattern at follow-up. Initial slow-phase eye velocities (SPVs) in biphasic HSN were larger than those in monophasic HSN at follow-up. Absence of HSN or reversal of its direction was closely related to normalized caloric responses, but SPVs of HSN did not correlate with the severity of CP. These findings indicate that the HSN test is a sensitive detector of vestibular hypofunction upon 2-Hz head rotation. HSN may reveal previous vestibular hypofunction in the 2-Hz frequency range even at follow-up, when caloric responses detecting vestibular hypofunction in the low-frequency range had normalized. The two tests utilize different mechanisms to assess vestibular hypofunction and are complementary. Biphasic paretic HSN is the most common pattern at follow-up and occurs when the initial SPVs induced by head rotation are large enough to induce the adaptation of primary vestibular afferent activity. Monophasic HSN, which is commonly found in dizzy patients, indicates less severe vestibular hypofunction than biphasic HSN in the 2-Hz frequency range, and the caloric tests can provide further information about the side and presence of vestibular hypofunction at lower frequencies.

BACKGROUND End-stage renal disease is associated with severe abnormalities in reproductive function. However, the abnormalities are reversed by successful kidney transplantation. The aim of the present study was to compare hormonal levels between recipients with successful kidney transplantations and healthy women with the same gynecologic conditions. METHODS The study group consisted of 31 women of reproductive age with end-stage renal disease who underwent successful kidney transplantation. The ratio of the control group, composed of healthy woman, to the study group was 3:1 matched for age and symptoms. RESULTS Abnormal bleeding (n = 14) and infertility were the most common gynecologic conditions in kidney transplant recipients. The levels of estrogen (E2) and follicle-stimulating hormone (FSH) in the study group were higher than in the control group, but the levels of progesterone (P4) and luteinizing hormone (LH) were lower in the study group than in the control group. There were no significant differences in prolactin and thyroid-stimulating hormone between the two groups. The incidence of infertility in patients who receive steroid was higher than those with no steroid use (P =.007). CONCLUSIONS Compared with healthy age- and symptom-matched women, female kidney transplant recipients have increased levels of E2 and FSH and decreased levels of P4 and LH. These differences in hormone profiles may predispose kidney transplant recipients to increased risk of gynecologic pathologies.

PURPOSE Proteinuria in the nontransplant population is a progressive renal disease. We analyzed the prevalence and clinical significance of proteinuria as well as factors related to its degree at posttransplant year 1 among kidney transplant recipients. METHODS We measured protein in a 24-hour urine among 644 recipients from January 1996 to December 2010. RESULTS Among 372 male and 272 female recipients, the mean amount of urinary protein was 424.4 ± 1010 mg/d (range, 13.88-8691) including 388 (60.2%) subjects with microproteinuria and the other 256 (39.8%) with overt proteinuria. Nephrotic range proteinuria was observed in 17 (2.6%) and nonnephritic range proteinuria, in 239 (37.1%) recipients. The latter cohort was categorized into low-grade proteinuria (n = 224; 34.8%) and high-grade proteinuria (n = 15; 2.3%). Proteinuria at posttransplant 1 year highly correlated with serum creatinine values at posttransplant years 1 and 2 as well as estimated glomerular filtration rate but not creatinine clearance at postoperative year 2. A greater incidence of graft loss was observed among recipients with more severe proteinuria. Males, recipients with anti-hepatitis C virus antibody, unrelated donors, anti-thymocyte immunoglobulin at the time of reperfusion, maintenance immunosuppression with cyclosporine or without mycophenolate mofetil were strongly associated with the amount of proteinuria. CONCLUSION This study demonstrated the prevalence of proteinuria in kidney transplant recipient to be high. The presence as well as level of proteinuria were predictive markers for inferior allograft function.

Background. This study investigated the acute effects of ethanol and acetaldehyde on physiological responses in healthy men according to ALDH2 genotype by measuring them directly in human blood. Methods. Twenty-four men, 12 with the ALDH2*1/*1 genotype and 12 with the ALDH2*1/*2 genotype, were selected. In a double-blind placebo-controlled crossover design, each subject was administered one of three doses of ethanol (0.25, 0.5 or 0.75 g/kg) or a placebo on four separate occasions. The blood ethanol concentration (BEC), blood acetaldehyde concentration (BAAC) and physiological responses including facial redness, pulse rate and systolic and diastolic blood pressures were assessed. Results. Significant differences were observed in the physiological responses between the ALDH2*1/*2 and ALDH2*1/*1 groups. Significant gene effects were observed for pulse rate and facial flushing (F-values = 62.344; p values < 0.001 and F-values = 7.062; p values = 0.010, respectively, by repeated-measures analysis of variance), which were significantly greater in subjects with the ALDH2*1/*2 genotype. In a linear regression analysis, BAAC significantly predicted increased facial redness at 30 minutes (adjusted R( 2 ): 0.209; p values < 0.001) and pulse rate at 30, 60, 90 and 120 minutes (adjusted R( 2 ): 0.454, 0.490, 0.428 and 0.193, respectively; all p values < 0.001), whereas BEC was not associated with any physiological response measure at any time. Conclusions. Facial redness and pulse rate after ethanol ingestion were significantly higher in the ALDH2*1/*2 genotype, and were significantly associated with blood acetaldehyde concentrations. The acute effects of ethanol on the physiological responses were mediated mainly by acetaldehyde, the active metabolite of ethanol, rather than by ethanol itself.

Epithelial-mesenchymal transition (EMT) is characterized by the loss of epithelial cell junction proteins and the gain of mesenchymal markers. The aim of this study was to analyze the associations between the EMT-related markers vimentin, E-cadherin, β-catenin, slug, snail, and twist1 and clinicopathologic parameters as well as epidermal growth factor receptor (EGFR) gene copy number and protein expression in non-small cell lung carcinoma (NSCLC). Fifty-nine squamous cell carcinomas (SCC) and 43 adenocarcinomas (AD) were immunohistochemically examined for respective EMT markers and for EGFR, using the EGFR PharmDx kit (Dako) for protein expression and automated silver enhanced in situ hybridization (SISH) for copy number. Vimentin expression in tumor epithelia was significantly higher in AD samples than in SCC samples (P=0.015). Among AD samples, vimentin expression was positively correlated with histologic grade (2 vs. 3; P=0.021) and exhibited a tendency toward a positive correlation with pTNM stage (I vs. II-IV; P=0.052). EGFR gene copy number was positively correlated with EGFR protein expression among both AD samples (P=0.008) and SCC samples (P=0.042), with EGFR protein expression being significantly higher in SCC samples compared with AD (P=0.038). Among AD samples, EGFR protein expression was associated with higher cytoplasmic expression of β-catenin (P=0.031). Among SCC samples, EGFR protein expression was negatively correlated with nuclear expression of β-catenin (P=0.033) but positively with nuclear slug (P=0.021). The expression pattern of EMT markers in AD suggests that vimentin is a possible immunohistochemical predictor of tumor progression.
