Disease-Free Survival of Patients With Muscle-Invasive Bladder Cancer Treated With Radical Cystectomy Versus Bladder-Preserving Therapy: A Nationwide Study

PURPOSE

Although level I evidence is lacking that radical cystectomy (RC) is superior to bladder-preserving therapy (BPT), RC is still advocated as the recommended treatment in patients with nonmetastatic muscle-invasive bladder cancer (MIBC). This study sought to compare the survival of patients with MIBC treated with BPT versus those treated with RC.

METHODS AND MATERIALS

All patients with nonmetastatic MIBC diagnoses were identified via the population-based Netherlands Cancer Registry. Only patients treated with BPT or RC were included. The primary endpoint was 2-year disease-free survival (DFS), defined as time from start of treatment until locoregional recurrence, distant metastasis, or death. The secondary endpoint was overall survival (OS). Inverse propensity treatment weighting (IPTW) was used based on propensity scores to adjust for baseline differences between treatment groups. Survival was analyzed with Kaplan-Meier and Cox proportional hazards models.

RESULTS

A total of 1432 patients were included, of whom 1101 underwent RC and 331, BPT. Median follow-up was 39 months (range, 27-51 months). The IPTW-adjusted 2-year DFS was 61.5% (95% CI, 53.5%-69.6%) with BPT and 55.3% (95% CI, 51.6%-59.1%) with RC, with an adjusted hazard ratio of 0.84 (95% CI, 0.69-1.05). The adjusted 2-year OS for patients treated with BPT versus RC was 74.0% (95% CI, 67.0%-80.9%) versus 66.0% (95% CI, 62.7%-68.8%), respectively, with an adjusted hazard ratio of 0.80 (95% CI, 0.64-0.98).

CONCLUSIONS

There was no statistically significant difference between the 2-year DFS of patients treated with BPT and RC. We propose that both RC and BPT should be offered as a curative treatment option to eligible patients with nonmetastatic MIBC.

Body attention, ignorance and awareness scale: assessing relevant concepts for physical and psychological functioning in psoriasis

A certain level of attention to bodily signals may be adaptive in the management of chronic skin conditions, as a lack of attention may lead to inadequate self-care behaviour and, consequently, may affect functioning and treatment outcomes. The purpose of this study was to develop a body awareness questionnaire and to investigate its psychometric properties and physical and psychological correlates in a cross-sectional study in patients with psoriasis (n = 475). The 16-item Body Attention, Ignorance and Awareness Scale demonstrated a 3-factor structure that could be interpreted as body ignorance, body attention, and body awareness (Cronbach's α of 0.73, 0.74, and 0.68, respectively). Higher body ignorance was significantly related to more physical symptoms and worse psychological functioning. Body attention and body awareness showed small significant correlations with coping and personality. Given the negative influence of impaired psychological functioning on treatment outcomes, it may be clinically important to screen for theses constructs of body awareness in chronic skin conditions.

Reliability, responsiveness and validity of Scalpdex in children with scalp psoriasis: the Dutch study

This aim of this study was to validate the Scalpdex, a quality of life questionnaire for adults with scalp dermatitis, in children with scalp psoriasis. The reliability, responsiveness and validity of the 3 scales (symptoms, functioning and emotions) of this 22-item questionnaire were analysed in a cohort of children with scalp psoriasis (age range 6-18 years). A total of 94 children completed the questionnaire once, and 53 children a second time, after treatment of their scalp psoriasis. The Children's Scalpdex in Psoriasis (CSP) demonstrated reliability with internal consistency (Cronbach's α, 0.69-0.91). The CSP scales proved sensitive to change in the expected direction for children whose scalp psoriasis improved. Moderate effect sizes were observed between both visits for all 3 scales of the CSP (Cohen's d, 0.44-0.58). In conclusion, the CSP is a reliable, responsive and valid questionnaire, which is the first to illustrate the specific influence of scalp psoriasis on quality of life in children.

Prediction of bacterial meningitis in children with meningeal signs: reduction of lumbar punctures

Physicians often have to perform a lumbar puncture to ascertain the diagnosis in patients with meningeal signs, because of the serious consequences of missing bacterial meningitis. The aim of this study was to derive and validate a clinical rule to predict bacterial meningitis in children with meningeal signs, to guide decisions on the performance of lumbar punctures. Information was collected from records of patients (aged 1 mo to 15 y) consulting the emergency department of the Sophia Children's Hospital between 1988 and 1998 with meningeal signs. Bacterial meningitis was defined as cerebrospinal fluid (CSF) leucocyte count >5 cells microl(-1) with a positive bacterial culture of CSF or blood. The diagnostic value of predictors was judged using multivariate logistic modelling and area under the receiver operating characteristic curves (ROC area). In the derivation set (286 patients, years 1988-1995) the duration of the main complaint, vomiting, meningeal irritation, cyanosis, petechiae and disturbed consciousness were independent clinical predictors of bacterial meningitis. The ROC area of this model was 0.92. The only independent predictor from subsequent laboratory tests was the serum C-reactive protein concentration, increasing the ROC area to 0.95. Without missing a single case, this final model identified 99 patients (35%) without bacterial meningitis. Validation on 74 consecutive patients in 3 subsequent years (1996-1998) yielded similar results.

CONCLUSION

This prediction rule identifies about 35% of the patients with meningeal signs in whom a lumbar puncture can be withheld without missing a single case of bacterial meningitis. For the individual patient this prediction rule is valuable in deciding whether or not to perform a lumbar puncture.

Do postnatal glucocorticoids and retinopathy of prematurity relate?

To study a possible relation between the use of postnatal glucocorticoids and the incidence and severity of retinopathy of prematurity (ROP), we conducted a retrospective study over a 4-year period that compared data of 161 preterm infants treated with hydrocortisone for bronchopulmonary dysplasia (BPD) with the data of 253 controls. The incidence of overall ROP was 62.7% in the hydrocortisone group and 21.3% in the control group. The incidence of severe ROP (stages 3-5) was 5% in the treatment group and 0.4% in the control group. Using logistic regression, postnatal hydrocortisone therapy was not associated with an increased risk for ROP or severe ROP (OR 1.387, 95% confidence interval 0.773-2.489, p = 0.272 and OR 4.112, 95% C.I. 0.44-38.37, p = 0.16, respectively). Also, in a subgroup of extremely low-birth-weight infants (<1000 g), postnatal hydrocortisone had no influence on the incidence of (severe) ROP. In the infants with ROP (n = 155), only prolonged use of postnatal hydrocortisone was associated with an increased risk for severe ROP (OR 1.02, 95% C.I. 1.00-1.03, p = 0.03). In this study postnatal use of hydrocortisone was not associated with an increased risk for (severe) ROP. However, in infants already suffering from ROP, prolonged treatment with hydrocortisone concurred with an increased risk for severe ROP.

New developments in neonatology: less severe retinopathy of prematurity?

PURPOSE

To determine the effects of surfactant replacement therapy (SRT), high-frequency oscillatory ventilation (HFOV), and general improvements in quality of care on the incidence of severe retinopathy of prematurity (ROP).

METHODS

Retrospective comparison of the incidence and severity of ROP in two groups of preterm infants admitted to our neonatal intensive care unit (NICU) in two consecutive 5-year periods (1986-1995) and screened for ROP. During the second study period, natural surfactant was introduced in the treatment of respiratory distress syndrome (RDS) and HFOV was used for treatment of respiratory insufficiency of any origin. The effects of these developments and general improvements on the incidence of severe ROP were analyzed with stepwise logistic regression.

RESULTS

The overall incidence of ROP from 1986-1990 was not significantly different from the incidence of ROP from 1991-1995. The incidence of severe ROP (ROP stage 3 or greater) was significantly lower in the second period (15.7% versus 6.4%, P=.015). For infants <1000 g, the incidence of overall ROP was increased significantly during the second study period (47.6% versus 60.1 %, P=.045), although the incidence of severe ROP remained unchanged. Only SRT was associated with a decreased risk for severe ROP; HFOV and general improvements in quality of care had no influence on the outcome. In patients with RDS, the incidence of severe ROP decreased significantly during the second period.

CONCLUSION

Of the recent new developments in neonatology, only SRT was associated with a decreased risk for severe ROP.

[Many chronic problems in CVA patients at home]

OBJECTIVE

To find out what the late implications of a stroke were for patients and relatives and whether specific requests for help existed.

DESIGN

Cross sectional study.

SETTING

Academic Hospital Nijmegen, department of Neurology and Sint Maartenskliniek (rehabilitation centre), The Netherlands.

METHOD

Patients who had sustained a cerebrovascular accident (CVA) in the last five years were asked, using the sickness impact profile (SIP), about their subjective functioning and the effect of the CVA on daily life. They were also asked about the degree to which they experienced their complaints as a problem, and whether they needed help.

RESULTS

In this study 165 patients and their close relatives filled out the SIP. Stroke had a very high impact on everyday functioning as indicated by a total SIP score of 20. The results further showed that psychosocial problems arise independently of the degree of physical problems, that these problems were chronic, and that psychosocial problems hindered 52% of the patients often to always. The physical problems hindered 60% of them often to always. A third of the patients wanted help for their physical problems, a quarter for their psychosocial problems.

CONCLUSION

The impact of stroke on both patients and their relatives was extensive and appeared chronic. There was need for physical and psychosocial help in a third or quarter of the cases.
