Prognostic value of MIB-1 score, p53, EGFr, mitotic index and papillary status in primary superficial (Stage pTa/T1) bladder cancer: a prospective comparative study. The Finnbladder Group.

OBJECTIVE: A prospective randomized study was undertaken to determine whether cell proliferation indices (M/V index, MIB1), papillary status, the expression of p53 and epidermal growth factor receptor (EGFr) have prognostic value in superficial (pTa-pT1) bladder cancer (SBC). METHODS: 207 patients with primary SBC were followed up over a period of 4.9 (range 3.7-6.0) years. M/V index and papillary status were assessed by light microscopy, and expression of MIB1, p53 and EGFr was assessed by immunohistochemistry. The results of histopathological analyses were related to the survival data of the patients. RESULTS: Using univariate analysis, stage (p < 0.001), grade (p < 0.001), papillary status (p < 0.001), MIB1 (p < 0.001), M/V index (p < 0.001), EGFr (p < 0.001) and p53 (p = 0.002) were significant predictors of progression. Using multivariate analysis, MIB-1 score and papillary status were independent predictors of progressive disease and cancer-specific survival. Tumor grade was the only independent predictor of recurrence. CONCLUSION: Evaluation of tumor cell proliferation rate by M/V index or by MIB1 immunohistochemistry and assessment of papillary status by light microscopy are useful prognostic tools in tailoring treatment and follow-up schedule of patients with SBC.     

Relationship of life satisfaction to impairment, disability, and handicap among persons with spinal cord injury living in the community.

The level and correlates of the life satisfaction of persons with spinal cord injury who are residing in the community were investigated. One hundred men and 40 women were chosen randomly from a cohort of 640 persons with spinal cord injury residing in a 13-county area in southeast Texas. The mean Life Satisfaction Index-A (LSIA-A) was lower than reported previously for persons in the general population. The LSIA-A was not correlated significantly with chronologic variables, the ASIA Total Motor Index Score, or a self-report version of the Functional Independence Measure. The LSIA-A was associated positively with self-assessed health, perceived control, and social support, as well as with the Social Integration, Occupation, and Mobility dimensions of the Craig Handicap Assessment and Reporting Technique. From the standpoint of an augmented version of the World Health Organization model of disablement, the life satisfaction of persons with spinal cord injury appears to be influenced, albeit indirectly, by selective aspects of their social role performance (handicap), but not by their degree of impairment or disability.     

Predicting consistency of pain over a 10-year period in persons with spinal cord injury

This longitudinal study was designed to test the hypothesis that persons who consistently report pain at three (women) or four (men) measurement points across 10 years (1988 to 1998) are different both physically and psychologically from those who inconsistently or never report pain. Participants were 96 persons with spinal cord injury (SCI) living in the community who participated at every measurement point. Measures included consistency of reports of pain (i.e., reported having had problems with pain in the 12 months prior to all, some, or no measurement points); demographic and injury-related data; and measures of physical and psychological health, function, and social support. Of the 96 participants, approximately half of the men and three-fourths of the women consistently reported pain at each point. Phase 1 predictors of the consistency of pain reports for men were being less impaired, being more independent, experiencing more stress, and receiving less social support. Women consistently reporting pain had more stress at Phase 1 than women inconsistently reporting pain. Persons with SCI at risk for chronic pain should be identified and referred to a multidisciplinary pain management program.     

Predictive value of N-terminal pro-brain natriuretic peptide in severe sepsis and septic shock

OBJECTIVE: The aim of this study was to evaluate the predictive value of N-terminal pro-brain natriuretic peptide (NT-proBNP) on mortality in a large, unselected patient population with severe sepsis and septic shock. DESIGN AND SETTING: Prospective observational cohort study about incidence and prognosis of sepsis in 24 intensive care units in Finland (the FINNSEPSIS study). PATIENTS: A total of 254 patients with severe sepsis or septic shock. MEASUREMENTS: After informed consent, the blood tests for NT-proBNP analyses were drawn on the day of admission and 72 hrs thereafter. Patients' demographic data were collected, and intensive care unit and hospital mortality and basic hemodynamic and laboratory data were recorded daily. MAIN RESULTS: NT-proBNP levels at admission were significantly higher in hospital nonsurvivors (median, 7908 pg/mL) compared with survivors (median, 3479 pg/mL; p = .002), and the difference remained after 72 hrs (p = .002). The receiver operating characteristic curves of admission and 72-hr NT-proBNP levels for hospital mortality resulted in area under the curve values of 0.631 (95% confidence interval, 0.549-0.712; p = .002) and 0.648 (95% confidence interval, 0.554-0.741; p = .002), respectively. In logistic regression analyses, NT-proBNP values at 72 hrs after inclusion and Simplified Acute Physiology Score for the first 24 hrs were independent predictors of hospital mortality. Pulmonary artery occlusion pressure (p < .001), plasma creatinine clearance (p = .001), platelet count (p = .03), and positive blood culture (p = .04) had an independent effect on first-day NT-proBNP values, whereas after 72 hrs, only plasma creatinine clearance (p < .001) was significant in linear regression analysis. CONCLUSION: NT-proBNP values are frequently increased in severe sepsis and septic shock. Values are significantly higher in nonsurvivors than survivors. NT-proBNP on day 3 in the intensive care unit is an independent prognostic marker of mortality in severe sepsis.     

Outcomes of intestinal failure—a comparison between children with short bowel and dysmotile intestine

Background

We investigated whether mortality, intestinal adaptation, and liver function differ between intestinal failure (IF) patients with either short bowel (SB) or bowel dysmotility (DM).

Patients and methods

Twenty-six consecutive patients with SB (n = 20) or DM (n = 6) treated between 2000 and 2007 were retrospectively assessed. Intestinal failure was defined as less than 25% of age-adjusted small intestinal length or dependence on parenteral nutrition (PN) more than 6 months.

Results

Median age-adjusted small intestinal length (17% vs 45%) and gestational age (35 vs 40 weeks) were (P < .05) shorter, whereas proportion of the remaining colon (86% vs 0%) was (P < .05) higher in the SB group relative to the DM group. Overall survival was 92%. Median peak serum bilirubin (80 vs 25 μmol/L) and rate of cholestasis (11/20 vs 0/6) were higher (P < .05) in the SB group. Short bowel rather than DM as an etiology of IF predicted weaning off PN (RR, 39.3; 95% confidence interval [CI], 1.43-526; P < .01) and development of cholestasis (risk ration [RR], 18.3; 95% CI, 0.658-127; P < .05). Three SB children developed liver failure and two died, whereas neither of these occurred in the DM group.

Conclusions

Children with SB are more likely to wean off PN but more prone to cholestatic liver disease than those with DM as an etiology of IF.     

A novel mutation of the GAA gene in a Finnish late‐onset pompe disease patient: Clinical phenotype and follow‐up with enzyme replacement therapy

Pompe disease is a rare, progressive disease leading to skeletal muscle weakness due to deficiency of the acid α‐glucosidase (GAA) enzyme. Herein we report the first diagnosed Finnish patient with a phenotype compatible with the late‐onset form of Pompe disease. Molecular genetic analysis of the GAA gene revealed a novel missense mutation, 1725C>A (Y575X), combined with a previously reported mutation, 1634C>T (P545L). Human recombinant α‐glucosidase enzyme (alglucosidase‐α) treatment was initiated for this patient at age 20 years. After 12 months she was no longer fully wheelchair‐bound, and muscle strength had improved. No disease progression was visible on muscle magnetic resonance imaging of the lower limbs, and the energy state of the muscle cells increased by 46% on phosphorus magnetic resonance spectroscopy. Overall, our findings suggest that enzyme replacement therapy is indicated, even in patients with late‐onset Pompe disease, to halt disease progression and improve the quality of daily life.

Sentinel Node Biopsy in Breast Cancer Patients with Large or Multifocal Tumors

Background  The axillary recurrence (AR) rate after negative sentinel node biopsy (SNB) in patients with high risk of axillary metastases is largely unknown. The aim of this study was to analyze the risk factors for isolated AR after negative SNB with special interest in large or multifocal tumors. Methods  A prospective SNB registry was analyzed for 2,408 invasive breast cancer patients operated between 2001 and 2007. No axillary clearance was performed in 1,309 cases with a negative SNB, including 1,138 small unifocal tumors, 121 small multifocal tumors, 48 large unifocal tumors, and 2 large multifocal tumors. Results  Six (0.5%) isolated AR were observed during a median follow-up of 43 months. Four (0.4%) patients with small unifocal tumors and two (1.6%) with small multifocal tumors had isolated AR (p = 0.179). None of the patients with large unifocal or multifocal tumors had isolated AR. Instead of tumor size and multifocality, estrogen receptor negativity (p < 0.001), nuclear grade III (p < 0.001), Her-2 status (p = 0.002), no radiotherapy (p = 0.005), and mastectomy (p = 0.005) were found to be associated with AR. Conclusions  A remarkable proportion of patients with large unifocal tumors and small multifocal tumors may avoid unnecessary AC due to tumor negative SNB, without an excessive risk of AR.
